Administrative Benchmark/Hard Core Internal Detailed Interpretation of Weilai ET7 Chassis Structure

[car home] Many people may still remember that the SkyRide· Tianxing chassis gave the industry a little pinch when Weilai ET9 was released in the middle of the year, but before the official listing of ET9, ET7 was still the flagship executive car that Weilai was currently selling. The "flagship" should naturally have the level that the flagship should have. In comparison with Mercedes-Benz E-Class and BMW 5 Series at the same level, ET7 has achieved a level that does not fall in the wind. Now we have to see if its mechanical quality and hardware level can carry the banner of brand administrative benchmarking.

■ Chassis front structure

Since entering the NT2.0 era, the improvement of the overall hardware quality of Weilai Automobile is obvious to all. As the first car with a brand-new platform of NT2.0, this (|) 100kwh executive version we shot this time is also the second top model in the car series, equipped with a front permanent magnet and a rear asynchronous dual-motor four-wheel drive system. Before the official start, we have to mention some technical details about ET7 BIW.

Home of the car

As a medium-sized and large-sized executive car with luxury and pure electricity, the curb weight of ET7 is about 2.3 tons, and the total weight of ET7′ s steel-aluminum mixed structure body-in-white is nearly 445kg, including 39.8% aluminum and 60.2% steel. Among them, high-strength steel and super-rigid steel account for 73%, and submarine-grade thermoformed steel accounts for 44% in the upper body structure. The material of the whole ET7 body frame can be described as very solid.

The front suspension of the vehicle adopts the double wishbone structure common in luxury cars, all the control arms are made of forged aluminum parts, and the upper and lower control arms are designed with double ball heads. The whole structural layout is very similar to Volkswagen’s high-end MLB Evo platform. The structural design of the virtual kingpin can further enhance the accurate driving and control experience. The virtual kingpin is formed by the intersection of the connecting lines of two independent swing arms, which changes with the rotation of the wheel during steering, and the position of the steering point can be closer to the wheel center, thus enhancing the ability to resist the fluctuation of longitudinal force, and achieving a more stable driving experience under extreme working conditions such as sharp acceleration and sharp turning. It is worth mentioning that the front lower control arm of ET7 is also equipped with a hydraulic bushing with carbon fiber subassemblies, which provides both control and comfort and greatly improves durability.

■ Chassis rear structure

Coming to the rear of the vehicle, the aluminum content of Weilai ET7 here is much higher than that of the front part. The first thing that catches the eye is the full-frame rear axle subframe made of integrated hollow cast aluminum technology, which has high strength and light weight, and can also control the total weight well with the larger rear axle asynchronous motor. In addition, hydraulic rubber sleeves with better anti-vibration performance and higher cost are used in the connection part between the subframe and the car body of the rear axle. The asynchronous motor at the rear axle is also covered with a large area of sound insulation sponge, and the thickness of the sponge is considerable.

■ Some other details

In other respects, considering that Weilai ET7 is an electric car, its chassis flatness is beyond doubt. When the chassis guard is not removed, the flatness of the whole car bottom can’t be compared with any oil car.

In addition, Weilai has also considered the battery’s protection ability very thoughtfully. This large battery cell with 100kwh is provided by Contemporary Amperex Technology Co., Limited, and the design and packaging of the battery are completed by Weilai. In order to take into account the demand for power exchange, the battery pack and the body frame have been doubly strengthened. All Weilai models adopt high-strength multi-cavity extruded aluminum doorsill, which forms a strong structure with the cross beam of the car body floor, and the lateral strength can bear 300KN pressure, covering both sides of the whole high-voltage battery module, providing the first safety guarantee.

Home of the car

The shell of the battery is also made of high-strength aluminum material, protected by double-layer aluminum plate and very strong honeycomb structure, which optimizes the mechanical structure and adds multi-channel reinforcement design. Under the condition of normal collision or hanging bottom, the internal battery cell will not catch fire or explode. At the same time, the battery pack reaches the IP69K standard, which is completely dustproof and can resist the impact of high pressure and high temperature water flow.

Home of the car

Thanks to the advantages of changing electricity, the owners of Weilai brand can minimize the safety hazards of battery packs by changing electricity. Through the power exchange system, Weilai can automatically eliminate the old batteries with low health and high safety hazards in the power exchange station, and constantly replenish new batteries to ensure that the owner can replace the batteries with double guarantees of safety and performance every time.

Home of the car

In addition, the air suspension of Weilai ET7 is standard in the whole system, providing comfort, energy saving, sports and sports+four driving modes. According to different driving modes, not only can the suspension height and hardness be adjusted actively at all times, but also the owner can choose the height individually, so as to realize the three-speed adjustment of-10 mm/0/40 mm. Thanks to the intelligent electric vehicle architecture, the electronic control functions in the chassis suspension system can be upgraded online through the FOTA of the whole vehicle, so that users can use the latest and optimized control program in the first time and constantly refresh the driving experience.

Edison Chen’s NFT record collapsed across the board? Earn 38 million, fans lose 2,000 yuan per capita?

  In terms of art itself, NFT is like a shortcut, more like a joke.

  In the era without NFTs, the threshold of art was too high to reach. Artists spent ten years carving their works, cultivating their own style and language through experience, crossing single-plank bridges, crowding into galleries, exhibitions, and limited events, gaining favor at the cost of time.

  Only when they have enough talent and are favored by capital can artists hope to rise to a higher level, write seven or eight-digit trading myths in the secondary market, and complete the incubation. The whole process is interconnected, one step at a time, and none of them are indispensable.

  NFTs have infinitely compressed this process, and art has achieved an unprecedented low threshold and high dissemination. In a sense, the emergence of the meta-universe and its derivatives, NFTs, has rewritten the laws of the market. Brands, investment institutions, and opinion leaders in the traditional consumer sector are sensitive and vicious, and they are not stingy with enthusiasm. They have started a new marketing model.

  The era breeds myths, and NFT is undoubtedly the product of the epidemic superimposed Web 3.0 period, which is unique.

  In response to the booming European and American markets, Asian and even Chinese native IP is not to be outdone.

  Taking the form of NFT promoted by a group of opinion leaders as an entry point, such as the BAYC boring ape avatar started by Chairperson Zhou and the Cryptopunk pixel series started by Yu Wenle, after paving the way for a high enough popularity of the public, they are not satisfied with continuing to "bring goods" for others, but self-develop and replay this trendy game.

  Among them, Edison Chen can be regarded as the most decisive one. From beginning to end, he has been regarded as a synonym for "not following the trend, and he is also the trend itself". By analyzing it as a sample, we can roughly glimpse the opportunities and predicaments of today’s NFTs.

  EDC first established platform 2426C to develop a series of virtual art products. The first round of products, RED NVLPE series, includes Dr. Woo, Heart NFT x Emotionally Unavailable, XIN YU, James Fauntleroy, CLOT, EDC x EGRA, Objective Collectibles, and Sandra Jockus, with a total of 8,888 artworks.

  In the field of traditional art collection, Edison Chen is not a novice, so he entered the venue with a firm and upright attitude, knowing that in NFT art, NFT is a form, and the focus is on the art itself.

  As well as tapping into different types of artists who can be distinguished, looking at completely different art combinations, claiming that his goal is "Gagosian in the field of NFT".

  Gagosian, who has handled Picasso, Mondrian, and Andy Warhol, is known as the Nasdaq of the art world – implying that he is a system of exchange, setting prices and rules. The public can know that Edison Chen’s ambitions are great, and others may be playing with tickets. They follow the trend of fashion and add an identity title, but EDC is as serious as ever.

  The fact is that he is really serious. Since the initial release of 2426C, he has personally released video tutorials, his wife and daughter appeared on the camera to promote, named other influential opinion leaders to help with platform delivery, and even empowered individual NFT holders with special rights – lifetime ownership of Clot x Nike shoes, etc., which can be said to spare no effort.

  The process is gorgeous, the ending is bleak, the NFT issued by 2426C in February was sold at 0.1888ETH, plus the handling fee was about 4724 yuan, 8888 works brought nearly 38 million yuan of income to EDC, and the most popular EDC x EGRA, that is, the thorn product designed by himself as the prototype, has both popularity and visual effect, has fallen through the issue price, the lowest touch 0.108ETH, about 2012 yuan.

  That is to say, the average investor who entered the market lost 2,162 yuan, and even the works of the other seven artists even fell to 0.03 ETH (about 558 yuan), leaving no one interested.

  No matter how you look at it, it is far from "Gagosian in the field of NFT".

  The shortcut was reflected. Bringing together these artists might have been a long project in the past, and the material and labor costs consumed in the middle were difficult to calculate. In the form of NFT, everything became very easy and full of black humor.

  In fact, Edison Chen is just one of the most extreme example, his own brand value and influence is undoubtedly a pioneer, and it has fallen to this point. Most domestic NFTs are facing the same dilemma. Zhou Dong’s Phanta Bear and Yu Wenle’s ZOMBIE are all just passable, and well-known IPs such as Leng Rabbit and Ali have also been mocked by the group.

  In the final analysis, the problems of domestic NFTs cannot escape the following basics: technical loopholes, far from the actual situation, fragmented operating methods, etc., which undoubtedly make themselves as vulnerable as a babbling baby in front of the huge NFT market in Europe and the United States.

  What does a successful NFT capture when it captures the masses?

  This form born in the meta-universe undoubtedly represents the public’s sense of identity with the Web 3.0 era environment. We aspire to become digital natives in the crypto world one day when the technology matures in the future, without any real differences in race, wealth, and social status.

  Having the same NFT brings excellent narrative and background consensus, and finally creates a "sense of community", such as BAYC Boring Ape, which tells the story of a group of apes who became rich from cryptocurrency and inevitably fell into boredom forming a club, mirroring the current situation of ordinary people getting rich quickly from cryptocurrency in the real world, representing a native era culture.

  In the Web 3.0 concept of "decentralization" and the egalitarian nature of the community, we use the simplest form – an avatar as an example, to find resonance with specific community members, while indulging in an artificially attached broad narrative to further create an immersive sense of enjoyment.

  Coincidentally, not only domestic NFTs are still struggling, but the European and American markets where the meta-universe originated are also discussing whether "NFTs have stalled" – in March 2021, Jack Dorsey, the co-founder of Twitter’s CEO at the time, sold an NFT cast in December 2020, the content of which was the world’s first tweet published in 2006.

  Then, the cryptocurrency entrepreneur Sina Estavi bought it for $2.90 million, which won the explosive traffic attention of the entire NFT form at that time. This NFT tweet was also called the "Mona Lisa of the digital age", which indirectly contributed to the rise of the entire market.

  On April 7 this year, Sina intended to sell the OpenSea platform trademark at $48 million, and received a total of 7 bids after the first round of bidding period, with a minimum of 0.0019 ETH (about $5.8) and a maximum of 0.09 ETH (about $277).

  From $2.90 million to $277, it seems like a myth died down, but behind it is the real awakening of the market: the gimmick brought by the NFT has been fooled by the public, even if the target is the "world’s first tweet", people are starting to care about the real value proposition of the NFT, that is, "I bought it, what else did I get except for it".

  "Owning a pair of sneakers will allow me to find like-minded players, owning a trendy game will allow me to meet another half with the same taste, and owning an NFT will also give me more social capital."

  A sense of belonging, a shared vision, a spontaneous voice for the group to which one belongs, eventually merged into a macro-sense "culture" – this is the same law that has never been outdated in the minds of the general public in any era.

Last night, Xu Jiayin said harshly: Do these points well, Hengda will definitely be able to pay off the debt!

Hengda, which has fallen into the crisis of the capital chain, held the "Pledge Conference of Guaranteed Building" under the leadership of Xu Jiayin in early September, but its delivery volume in September, October and November was less than 10,000 sets.

Now that there are still five days left in 2021, how is Evergrande’s "Baojiao Building" going?

On the evening of the 26th, the official account of Evergrande Group disclosed the latest situation.

Xu Jiayin said at the weekly meeting of the resumption of work and production that night that all employees of the group, with the support and care of all sectors of society,After several months of hard work, the resumption of work and production to ensure the delivery of buildings has achieved initial results.

As of December 26, Hengda Group’s national project resumption rate was 91.7%, an increase of 40% from the beginning of September; the number of people who resumed work 89,000, an increase of 31% from September.

However, Xu Jiayin said that Evergrande’s goal is not to resume work and production, but to ensure quality assurance and hand over buildings to owners. The next stage of the group’s goal is to continue to increase the number of people who resume work to improve efficiency. "In December, the group has 115 projects scheduled to be delivered. There are still five days left in this month. We must sprint to ensure that we complete the goal of handing over 39,000 buildings this month."

Evergrande also revealed a message, saying that more than 80% of the main bodies and decoration units have resumed cooperation with Evergrande, and long-term cooperative material suppliers have also resumed supply, which has played a key role in the final hardcover project of "Baojiao Building".

Xu Jiayin also emphasized one point at the meeting.That is, "no one at Evergrande will be allowed to lie down. As long as we resume work and production at all costs and do a good job in engineering construction, we will definitely be able to deliver the house to the owner, and we will definitely be able to resume sales, resume operations, and pay off debts."

On the evening of the 22nd, China Evergrande announced that in response to the risks currently facing the group, the China Evergrande Group Risk Resolution Committee is mobilizing extensive resources and will actively maintain communication with creditors to resolve group risks and safeguard the legitimate rights and interests of all parties.

On the 24th, according to the Hong Kong Stock Exchange document, Hui Jiayin’s shareholding ratio in Evergrande Property fell from 60.96% to 58.18%, involving 300 million shares. The reason for the disclosure is that "the relevant parties have taken steps to enforce the guarantee interest in the shares against you or the right to hold the shares as security".

Prior to December 6, December 7, December 8, December 9, Xu Jiayin continued to be forced to sell China Evergrande 106 million shares, 120 million shares, 51.88 million shares and 7000 shares, a total of about 277.80 million shares, eventually Xu Jiayin in China Evergrande shareholding ratio fell from 61.88% to 59.78%.

On December 3, Evergrande issued an announcement announcing that a company was unable to meet its obligation to repay a $260 million private debt, a move that could lead to an accelerated maturity of the debt.

That evening, the Guangdong provincial government interviewed Xu Jiayin and, at the request of Hengda Real Estate Group, agreed to send a working group to Hengda Real Estate to effectively defuse risks and protect the interests of all parties.

One of the group’s main tasks at present is to ensure delivery, ensuring that more than 700 projects across the country can maintain normal operation and avoid unfinished business.
