Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to automotive seat parts. Background Technology

[0002] Currently, most passenger-operated footrests in ordinary sedans or commercial vehicles are manually operated, requiring rear passengers to manually open them. Some high-end and luxury models are equipped with electric footrests; however, existing electric footrests often have numerous components that reduce the space between the seat back and the rear seat, resulting in insufficient space for the footrest support structure and inadequate foot support, thus reducing the comfort of rear passengers. This improvement addresses the problem of insufficient foot support by allowing for a longer footrest support within the same space, thereby enhancing the comfort of the seat for passenger feet.

[0003] The technical problem to be solved by this application is: how to improve the problem of insufficient support length of automobile foot pedal structure. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 This utility model provides a technical solution: a vehicle foot pedal structure, including a support assembly 1, a drive assembly 2, and a backrest side panel. The support assembly 1 and the drive assembly 2 are disposed between two backrest side panels, and the drive assembly 2 drives the support assembly 1 to rotate.

[0017] The support assembly 1 includes a connecting shaft 11, an extension rod 12, a support tube 13, and a support bracket 14. The connecting shaft 11 is positioned between the backrest side panels, with both ends of the connecting shaft 11 fixedly connected to the corresponding backrest side panels. The connecting shaft 11 remains stationary relative to the backrest side panels. One end of the extension rod 12 rotates at its upper limit on the connecting shaft 11. The support tube 13 connects to the extension rod 12, with both ends of the support tube 13 fixedly connected to the corresponding extension rod 12. The two support tubes 13 and the two extension rods 12 enclose an installation space. The support bracket 14 is positioned within the installation space, with both ends of the support bracket 14 fixedly connected to the corresponding support tube 13. To balance the overall center of gravity of the support assembly 1, the support bracket 14 is connected to the center of the two support tubes 13. To enhance the support of the support assembly 1, a support wire 17 is provided between the two support tubes 13, with both ends of the support wire 17 fixedly connected to the support tube 13. The two support wires 17 are respectively positioned on both sides of the support bracket 14. During the flipping process, the support component 1 rotates around the connecting fixed axis 11 as the rotation center.

[0018] The drive assembly 2 includes a lead screw motor 21, a first connecting rod 22, and a second connecting rod 23. The fixed end of the lead screw motor 21 is fixedly connected to the support bracket 14, and the output end of the lead screw motor 21 moves in a direction away from or towards the connecting fixed shaft 11. The first end of the first connecting rod 22 is rotatably connected to the output end of the lead screw motor 21, and the second end of the first connecting rod 22 is rotatably connected to the second connecting rod 23 via a stepped bolt 24. The second connecting rod 23 is fixedly mounted on the outer wall of the connecting fixed shaft 11. That is, when the output end of the lead screw motor 21 moves, it forces a change in the distance between the first end of the first connecting rod 22 and the connecting fixed shaft 11. The first end of the first connecting rod 22 rotates around the stepped bolt 24, and the second end of the first connecting rod 22 also rotates with the output end of the lead screw motor 21, thereby causing the support assembly 1 to rotate around the connecting fixed shaft 11.

[0019] To facilitate the rotation of the support assembly 1 from the folded state to the usable state and the return of the buffer support assembly 1 to the folded state, in this embodiment, preferably, a return spring 15 and a fixed bracket 16 are provided on the outer wall of the connecting fixed shaft 11. The fixed bracket 16 is fixedly disposed on the outer peripheral surface of the connecting fixed shaft 11, and the return spring 15 is movably sleeved on the outer peripheral surface of the connecting fixed shaft 11 and disposed between the fixed bracket 16 and the extension connecting rod 12, preventing the return spring 15 from disengaging from its set position during movement. One end of the return spring 15 is fixedly connected to the extension connecting rod 12, and the other end abuts against the fixed bracket 16 when the support assembly 1 is folded.

[0020] In order to reduce the overall thickness and length of the support assembly 1, the connection end between the second link 23 and the first link 22 is located above the connecting axis 11, which is biased towards the support assembly 1.

[0021] The working principle and usage process of this utility model are as follows: When the drive screw motor 21 starts, it moves linearly inward along the screw axis, driving the first connecting rod 22. During this movement, the first connecting rod 22 rotates around the axis of the stepped bolt 24, thereby driving the support assembly 1 to rotate around the connecting fixed shaft 11. When the screw stroke reaches its maximum, the support assembly 1 is fully opened. When the drive screw motor 21 reverses electrically, it moves linearly back along the screw axis, driving the first connecting rod 22 to rotate back around the axis of the stepped bolt 24, thereby driving the entire support assembly 1 to rotate back around the connecting fixed shaft 11. When the screw stroke returns to its original position, the entire support assembly 1 is in a folded state.

[0022] By hiding the drive assembly 2 inside the foot pedal assembly, the space occupied by the drive assembly 2 between the seat back and the rear seat is reduced, saving space between the seat back and the rear seat. Moreover, the structure of the drive assembly 2 is simplified, and the assembly of the entire foot pedal structure is less difficult and has lower process requirements.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
