Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a folding electric pedal linkage mechanism with the vehicle body. Background Technology
[0002] Folding pedals are retractable pedals installed on the side skirts or chassis edges of vehicles, typically unfolded / folded electrically or mechanically. When folded, they lie flat with the vehicle body; when needed, they can be unfolded to provide foot support for passengers. These functional accessories, by flexibly extending and retracting, solve the problem of getting in and out of the vehicle, balancing convenience and vehicle maneuverability. However, existing folding electric pedals, when malfunctioning due to sudden short circuits or open circuits, lack a self-locking function, leading to missed steps and potential falls for passengers or drivers. While self-locking functions prevent missed steps, they prevent the pedal from being retracted, requiring repair at a shop, which is inconvenient. Therefore, a mechanism linking the folding electric pedal to the vehicle body is designed to solve these problems. Utility Model Content

[0023] 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.
[0024] Please see Figure 1-5This utility model provides a technical solution: a folding electric pedal and vehicle body linkage mechanism, comprising: an electric pedal 1 and a controller 2. The electric pedal 1 includes two mounting plates 11 with arc-shaped upper ends. The upper ends of the mounting plates 11 are connected to the lower end of the vehicle body by bolts. A rotating bracket 12 is fixedly connected to the lower end of the mounting plates 11. A driving rod 13 is rotatably connected to the lower end of the rear inner wall of the rotating bracket 12. A driven rod 14 is rotatably connected to the lower end of the front inner wall of the rotating bracket 12. A support frame 15 is rotatably connected to the lower ends of the driving rod 13 and the driven rod 14. A pedal 16 is bolted to the upper front end of the support frame 15. The outer rotating end of the active rod 13 extends to the outer side of the rotating bracket 12. The end of the active rod 13 is fixedly connected to the outer side of the rotating bracket 12 by a bidirectional ratchet fixing mechanism 17. A servo motor 18 is fixedly connected to the outer side of the bidirectional ratchet fixing mechanism 17. The swing end of the servo motor 18 is fixedly connected to the inner adjusting end of the bidirectional ratchet fixing mechanism 17. A rotating handle 19 is fixedly connected to the outer rotating end of the servo motor 18. A gearbox 20 is fixedly connected to the inner side of the active rod 13 on the right side. A motor 21 is fixedly connected to the rear input end of the gearbox 20. The controller 2 is electrically connected to the servo motor 18 and the motor 21. The controller 2 is electrically connected to the vehicle body control terminal.
[0025] In use, the controller 2 is installed at the lower end of the front cover and connected to the vehicle's control system. After the program is edited, the controller 2 is then connected to the servo motor 18 and the motor 21. The electric pedal 1 is installed at the lower end of the left and right sides of the vehicle body using bolts. When the door is opened, the vehicle sends an electrical signal to the controller 2, which then activates the servo motor 18 and the motor 21. The output end of the servo motor 18 rotates the adjusting end of the bidirectional ratchet fixing mechanism 17 to one side. The motor 21 drives the internal structure of the gearbox 20 to rotate, causing the drive rod 13 to rotate to one side, which in turn causes the driven rod 14 to rotate forward, and the support frame 15 extends forward. Extending outwards from the vehicle body, it can be used normally. In the event of a sudden power outage or damage, the bidirectional ratchet fixing mechanism 17 will lock the pedal 16, preventing it from retracting inwards and thus preventing the driver or passenger from stepping into empty space. When retraction is needed, simply turn the rotating handle on the outside of the servo motor 18 to adjust the bidirectional ratchet fixing mechanism 17 to the reverse direction, and then manually push the pedal 16 back. The bidirectional ratchet fixing mechanism 17 will lock the position and prevent it from falling off. In normal use, closing the door will send an electrical signal to the controller 2, causing the servo motor 18 and motor 21 to flip, and the pedal 16 will automatically retract.
[0026] like Figure 1-4 As shown in the figure, this utility model embodiment provides an implementation method. Based on the above implementation method, an RGB indicator light 22 is fixedly connected to the inside of the outer side of the pedal 16, and the RGB indicator light 22 is electrically connected to the controller 2.
[0027] Analysis of the above structure shows that when the pedal 16 is extended, the RGB indicator light 22 will be activated at the same time to mark the outline of the pedal, making it convenient for passengers to take the bus at night.
[0028] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which the upper end of the pedal 16 is at an angle of three to five degrees.
[0029] Analysis of the above structure shows that the upper end of the pedal 16 is at an angle of three to five degrees. When splashed water falls on the pedal 16, it will be left through the angle.
[0030] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the upper end of the pedal 16 is provided with guide grooves 23 in an array.
[0031] Analysis of the above structure shows that the guide groove 23 at the upper end of the pedal 16 can guide water and increase the friction between the surface and the sole of the shoe.
[0032] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a soft pressure sensor is wrapped around the outer side of the pedal 16, and the soft pressure sensor is electrically connected to the controller 2.
[0033] Analysis of the above structure shows that the soft pressure sensor is located on the upper side of the RGB indicator light 22. When the pedal 16 is extended and collides with an obstacle or a person, the soft pressure sensor will indicate the magnitude of the collision force. When the force exceeds the set pressure, the extension will stop and the pedal will retract by one to two centimeters.
[0034] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the front end of the lower surface of the pedal 16 extends to the lower front end of the support frame 15 and is connected by bolts.
[0035] Analysis of the above structure shows that the strength of the connection between the pedal 16 and the support frame 15 is increased.
[0036] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the mounting plate 11, rotating bracket 12, driving rod 13, driven rod 14, and the outer side extending to the support frame 15 are all coated with waterproof paint.
[0037] Analysis of the above structure shows that the waterproof coating applied to the mounting plate 11, rotating bracket 12, driving rod 13, driven rod 14, and the outer side extending to the support frame 15 can reduce corrosion and extend service life.
