According to foreign media reports, a patent application was filed recently, in which it said that it would improve the design of the center seat of semi truck and use a suspension system on the driver's seat structure to provide additional safety for the driver. According to the patent, the seats of semi-trailer trucks and other vehicles generally adopt the scissor lift design, that is to say, the rotating feet crossing each other are included to adjust the seats. However, the patent said there would be some flaws in the architecture, especially in the event of an accident. In the event of a collision, the extension of all seat belts (ABTS) requires that "the seat frame can bear the load of passengers and distribute the load to the body. However, this scissor leg design was not originally designed for the ABTS solution, and it is not efficient in load distribution. " Therefore, the purpose of the patent is to make the seats safer and more comfortable, and to save the lives of semi truck drivers in the long run. "For drivers, it is very important to adjust the seat height to ensure driving safety. For passengers, adjusting the height can increase comfort. The truck seat equipped with scissor lifting device can be lifted and lowered by the air bag under the seat, and the scissor leg can be lengthened according to the air bag inflation. " For truck drivers, safety and comfort are very important, because many drivers need to drive trucks all over the country. Many drivers' wages depend on the number of miles they drive in a shift, which results in the need for drivers to drive for a long time, so it is very important for drivers to feel comfortable and safe at any time. According to the federal highway administration, truck drivers can drive 45000 to 100000 miles a year, so truck manufacturers must design vehicles that are comfortable enough for drivers to drive for a long time. Tesla's design can increase safety in the event of a collision, and can also be applied to drivers of different heights. When adjusting the seat, the driver can inflate or deflate the air bag to raise or lower the position. Depending on the inflation degree of the airbag, the force of the spring will change, which will lead to different results in the event of an accident. Tesla said in the background of the patent: "for the comfort of passengers, many seats adopt suspension system. In the car seat with scissor lift design, air bag can also act as spring, provide suspension system, and act as shock absorber to absorb vibration. However, since airbags are also used to control the seat height, the ride characteristics are affected by the seat height adjustment. " Tesla plans to include such a suspension system through a "multi column structure" that connects the sleeve to several sets of lift links, and Tesla plans to modify the height adjustment system to match the suspension system of the seat. Tesla wrote in the patent: "the height adjustment system includes a four-bar connection device and is placed on the top of the suspension system. The vehicle seat also includes a plate relying on the suspension system, the sleeve is coupled with the plate, and the head and tail ends of the lifting link are pivotally coupled to the plate. The multi column structure includes a column coupled to a plate for moving back and forth on the track to adjust the height of the seat. " All in all, Tesla seems to be turning its semitrailer into the safest tractor trailer on the road. Safety is the company's top priority, and developing new ways to create a safer driving experience is exactly what Tesla outlined in its recent patent application. At present, many companies seeking more environmentally friendly logistics tools have ordered Tesla's semi-trailer truck model, which will start limited production in 2020.
