Abstract
Description
Technical Field
[0001] This utility model relates to the field of footrest structures, and in particular to a gear-driven electric footrest assembly. Background Technology
[0002] To accommodate different people and sitting postures, car footrests need to provide the ability to swing and fold. Since the footrest supports both feet, the force is relatively large, so the requirements for its support force and swing torque are high. Currently, the relevant solutions, such as the footrest disclosed in the patent document with announcement number CN218400330U, use a crank mechanism to drive the swing, which has insufficient driving torque and the foot pedal is prone to shaking. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a gear-driven electric footrest assembly. The left and right assist torsion springs play a role in eliminating the shaking during rotation, and after reaching the designated position, they also play a role in providing a force to the foot pedal rotation shaft to suppress shaking.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a gear-driven electric footrest assembly, including a back plate, a rotating shaft, a footrest, and a torsion spring;
[0005] The back plate is rotatably fitted with the rotating shaft;
[0006] The footrest is fixed to the rotating shaft;
[0007] The rotating shaft is driven by a motor;
[0008] A torsion spring is provided between the back plate and the footrest, and the torsion spring causes the footrest to swing and close relative to the back plate.
[0009] This design uses a rotating shaft to provide a hinge between the back panel and the footrest, enabling a more stable connection between the two and smoother movement of the footrest. The footrest unfolds via a motor and automatically retracts using a torsion spring, making it very convenient to operate.
[0010] Preferably, connecting blocks are distributed on the left and right sides at the lower end of the back plate, and each connecting block is provided with a rotating hole, into which the rotating shaft rotatably engages. This provides more stable support for the rotating shaft.
[0011] Preferably, the torsion spring is sleeved on the rotating shaft, and its two ends are respectively connected to the back plate and the footrest. A torsion spring sleeved on the rotating shaft provides greater stability.
[0012] Preferably, the torsion springs are distributed to the left and right of the connecting blocks.
[0013] Preferably, a driven gear is provided at one end of the rotating shaft, the motor is provided on the back plate, and a drive gear is provided at the output end of the motor. The drive gear transmits power to the driven gear through a transition gear. The transition gear allows for more flexible setting of the relative positions of the drive gear and the driven gear, resulting in more flexible spatial arrangement.
[0014] Preferably, the transition gear is rotatably engaged with the back plate portion to provide stable transmission.
[0015] Preferably, a speed reducer is provided between the motor and the drive gear to increase the transmission torque.
[0016] Preferably, the transition gear is an eccentric gear, which operates on the lever principle to provide the transmission torque and more stably drive the swing of the footrest.
[0017] Preferably, the eccentric gear has a long, narrow structure with teeth at both ends. The shaft of the eccentric gear is eccentrically positioned and rotatably engages with the back plate. Driving the eccentric gear to oscillate significantly increases its torque.
[0018] The beneficial effects of this utility model are:
[0019] It enables more stable and smoother movement of the footrest, and utilizes eccentric gears to increase drive torque and provide stronger power. Left and right assist torsion springs eliminate wobbling during rotation and, upon reaching the designated position, also apply force to the foot pedal shaft to suppress further wobbling.

[0025] Example
[0026] like Figure 1 As shown, the gear-driven electric footrest assembly includes a back plate 1, a rotating shaft 3, a footrest 2, and a torsion spring 4; the back plate 1 is rotatably fitted with the rotating shaft 3; the footrest 2 is fixed to the rotating shaft 3; the rotating shaft 3 is driven by a motor 10; the torsion spring 4 is provided between the back plate 1 and the footrest 2, and the torsion spring 4 drives the footrest 2 to swing and close relative to the back plate 1.
[0027] This design uses a rotating shaft 3 to provide a hinge structure between the back plate 1 and the footrest 2, which enables a more stable connection between the two and a smoother movement of the footrest 2. The footrest 2 is unfolded by the motor 10 and automatically retracted by the torsion spring 4, making it very convenient to operate.
[0028] Connecting blocks 5 are distributed on the left and right sides at the lower end of the back plate 1. Each connecting block 5 is provided with a rotating hole, and the rotating shaft 3 is rotatably fitted into the rotating hole. This can provide more stable support for the rotating shaft 3.
[0029] The torsion spring 4 is sleeved on the rotating shaft 3, and its two ends are respectively connected to the back plate part 1 and the footrest part 2. The torsion spring 4 sleeved on the rotating shaft 3 provides greater stability.
[0030] The torsion springs 4 are distributed on the left and right sides corresponding to the connecting blocks 5.
[0031] One end of the rotating shaft 3 is provided with a driven gear 6, and the back plate 1 is provided with a motor 10. The output end of the motor 10 is provided with a drive gear 8, and the drive gear 8 transmits power to the driven gear 6 through a transition gear 7. The transition gear 7 allows for more flexible setting of the relative positions of the drive gear 8 and the driven gear 6, resulting in more flexible spatial arrangement.
[0032] The transition gear 7 is rotatably engaged with the back plate portion 1 to provide stable transmission.
[0033] A speed reducer 9 is provided between the motor 10 and the drive gear 8 to increase the transmission torque.
[0034] The transition gear 7 is an eccentric gear, which operates on the lever principle to provide the transmission torque and more stably drive the swing of the footrest 2.
[0035] The eccentric gear has a long, narrow structure with teeth at both ends. Its shaft is eccentrically positioned and rotatably engages with the back plate 1. Driving the eccentric gear 8 to oscillate the eccentric gear significantly increases its torque.
[0036] The beneficial effects of this utility model are:
[0037] It enables more stable and smoother swing of the footrest 2, and utilizes eccentric gears to increase drive torque and provide stronger power. The left and right assist torsion springs eliminate wobbling during rotation, and after reaching the designated position, they also provide a force to the foot pedal rotation shaft to suppress wobbling.
