The two connecting strips 81 are connected by the movable column 91, and the fixed bearing 10 is installed at the connection point between the movable column 91 and the connecting strip 81. A folding box 11 is provided inside the seat back 2, forming a space for the movable column 91 to move up and down. The upper part of the folding box 11 is connected to the top of the seat back 2. The drive assembly also includes a transmission slide rail 12 and a motor 13. The transmission slide rail 12 is located on both sides of the folding box 11, and both ends of the movable column 91 are connected to the transmission slide rail 12. The motor 13 is connected to the upper part of the transmission slide rail 12.

[0046] In specific embodiments, multiple components need to interact and connect to achieve the desired result during implementation.

[0047] like Figure 4 This embodiment also provides a car seat back folding armrest control system, which controls the folding armrest as described above to rotate and fold along the seat back 2. The control system includes:

[0048] The position acquisition module is configured to acquire the folding or opening position data of the handrail handle 5 by the position of the transmission slide rail 12 and the movable column 91.

[0049] The IHU interaction module is configured to display the current status data of the handrail handle 5 and issue an opening request or a folding request for the folding handrail through the operator's instructions.

[0050] The CEM controller is configured to acquire the current status data of the handrail handle 5 through the motor 13 and the position acquisition module, and to feed back the current status data of the handrail handle 5 to the IHU interaction module.

[0051] The CEM controller is located inside the seat back folding armrest module 4, and the position acquisition module is located at the connection between the transmission slide rail 12 and the movable column 91.

[0052] The CEM controller and the IHU interaction module transmit data signals via a CAN controller local area network bus.

[0053] User manual implementation process

[0054] Initially, the armrest handle 5 is folded and retracted into the upper part of the seat back 2. When a user enters the vehicle, the force exerted on the armrest handle 5 while seated causes it to pull. This pull activates the connecting ring 7, which in turn drives the folding rod 8 and the connecting bar 81. The moving column 91 on the connecting bar 81 causes the folding box 11 to move up and down. As a result, the armrest handle 5 and the connecting bar 81 unfold downwards. The armrest handle 5 can be rotated via the connecting ring 7, and the force causes it to open and close mechanically. The armrest handle 5 is positioned in front of the passenger, and the folding rod 8 encircles the left and right sides of the rear passengers, thus ensuring the stability of the rear passengers.

[0055] Electrical control implementation process

[0056] Initially, the armrest handle 5 is folded up on the upper part of the seat back 2. When the user enters the vehicle, the IHU interactive module displays the current status data of the armrest handle 5. Upon command from the operator, a request to open the folding armrest is issued. The control motor 13 drives the transmission slide rail 12, which moves up and down in the folding box 11 via the movable column 91 on the connecting bar 81. This causes the armrest handle 5 and the connecting bar 81 to move downwards and unfold. The armrest handle 5 can be rotated via the connecting ring 7, and the force causes it to open and close mechanically. The armrest handle 5 is positioned in front of the passenger, and the folding rod 8 encircles the left and right sides of the rear passengers, achieving a level of stability protection for rear passengers. When it is necessary to fold it up, upon command from the operator, a request to fold the armrest is issued. The armrest handle 5 rotates to fold up, the movable column 91 moves upwards within the folding box 11, the armrest handle 5 is folded up, and the passenger leaves.

[0057] This invention also uses a mechanical transmission structure, but the structure of this application is a reconstruction to solve the related problems of seat armrests. Compared with the prior art, there is currently no folding armrest on the back of a car seat to increase the user experience of rear passengers and improve the stability of rear passenger ride.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
