The application discloses a manual zero-gravity skeleton with a manual leg support, which comprises a lower slide rail fixed to a vehicle body, an upper slide rail in sliding cooperation with the lower slide rail, a seat frame skeleton fixedly connected with the upper slide rail, a backrest skeleton, and an angle adjuster connecting the seat frame skeleton and the backrest skeleton. The application realizes zero-gravity adjustment through a pure mechanical structure, does not depend on a vehicle electrical system, has long service life and high stability of mechanical components, and can still adjust the seat when colliding and being powered off, thereby improving passive safety. Through linkage unlocking and pneumatic buffering, posture switching is smooth at a constant speed, and the switching is completed within 2-3 seconds, so that balance response speed and comfort are achieved. The leg support is driven by a torsional spring, is convenient and labor-saving, and supports a comprehensive leg support mechanism, the lifting power of which is provided by the torsional spring, is automatically positioned after being unlocked, reduces operation force, and realizes one-key unfolding. In cooperation with the zero-gravity posture, the application provides comprehensive support from legs to back for a passenger, and effectively disperses body pressure.

This invention belongs to the field of high-voltage connecting aluminum busbar technology, and specifically relates to a dual-conductor, dual-insulation high-voltage connecting aluminum busbar structure for electric vehicles. It includes: two sets of flat aluminum conductors arranged parallel to each other vertically; a high-temperature resistant insulating tape wrapped around the flat aluminum conductors, allowing the two sets of flat aluminum conductors to form independent positive and negative connecting wires respectively; and an outer insulating layer wrapped around the entire outer side of the positive and negative connecting wires. The manufacturing process of the high-voltage connecting aluminum busbar structure includes the following steps: aluminum busbar extrusion, insulating tape winding, outer insulating layer extrusion, cutting, 3D bending, peeling, conductor punching, labeling, and packaging. The flattened design of this invention significantly reduces vertical space occupation, making it suitable for wiring in narrow areas such as the top and side walls of the battery pack, improving the overall vehicle space utilization. Furthermore, the production process is simplified from 17 steps to 9 steps, reducing carbon emissions and aligning with green manufacturing trends.

The present application relates to a remote airbag device, comprising: a gas generator comprising a first igniter, a second igniter, a first gas outlet and a second gas outlet; an airbag body comprising a main cavity, an upper cavity and a lower cavity connected to the main cavity, wherein the upper cavity is in communication with the first gas outlet of the gas generator via a first inflation channel and the lower cavity is in communication with the second gas outlet of the gas generator via a second inflation channel, so that the upper cavity and the main cavity are inflated when the first igniter is activated, and the lower cavity and the main cavity are inflated when the second igniter is activated. Furthermore, the present application also provides a method and a control device for controlling the remote airbag device, and a vehicle equipped with the remote airbag device.
