[0002] With the rapid development of SUVs in the automotive industry, people have increasingly higher demands for the convenience and intelligence of getting in and out of SUVs. Therefore, electric intelligent side steps have emerged on the market, which can automatically deploy and retract the side steps on the sides of the SUV chassis, offering great convenience and intelligence. However, if the controller or motor of the electric side step malfunctions, or if the wiring is broken, or if the electronic control components fail, manually resetting or pulling out the electric side step becomes very difficult due to the self-locking characteristic of the motor. Ordinary car owners often find it difficult to manually reset or pull out the side step, and in many cases, professional technicians need to use specialized tools to perform the operation, causing some inconvenience. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a transmission device for an electric side pedal that can be manually reset or pulled out.

[0004] The objective of this invention can be achieved through the following technical solution: a transmission device for an electric side pedal, comprising:

[0005] An active drive mechanism, comprising a motor and an active linkage unit, wherein the motor and the active linkage unit are drively connected;

[0006] The driven drive mechanism includes a driven linkage unit, wherein the driving linkage unit and the driven linkage unit are respectively disposed at both ends of the pedal and are fixedly connected to the pedal;

[0007] Also includes:

[0009] In the aforementioned transmission device for an electric side pedal, the connecting unit includes a connecting shaft, which is detachably connected to the output shaft of the motor, and the active linkage unit is fixedly connected to the connecting shaft.

[0010] In the above-mentioned transmission device for an electric side pedal, the connecting shaft includes a hollow shaft, which is sleeved on the output shaft of the motor and can rotate relative to the output shaft of the motor. The active linkage unit is fixed to the hollow shaft, and a locking unit is provided between the hollow shaft and the output shaft of the motor, so that the hollow shaft can rotate with the output shaft of the motor or the hollow shaft can rotate relative to the output shaft of the motor.

[0011] In the aforementioned transmission device for an electric side pedal, the locking unit includes a locking nut, and a plurality of openings are arranged circumferentially on the hollow shaft. An external thread is arranged around the opening on the hollow shaft, and the locking nut is screwed into the external thread.

[0012] In the aforementioned electric side pedal transmission device, a plurality of the openings are arranged circumferentially at the end of the hollow shaft away from the motor.

[0013] In the aforementioned transmission device for an electric side pedal, the active linkage unit includes an active bracket and a base frame.

[0024] In the diagram, there is a motor 100; a connecting shaft 200; an opening 201; a locking nut 202; an active support 300; a base frame 301; an inner connecting plate 302; an outer connecting plate 303; and a pedal 400. Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0027] like Figures 1-5 As shown, a transmission device for an electric side pedal includes:

[0028] An active drive mechanism includes a motor 100 and an active linkage unit, with the motor 100 and the active linkage unit being drivenly connected.

[0029] The driven drive mechanism includes a driven linkage unit, an active linkage unit and a driven linkage unit, which are respectively disposed at both ends of the pedal 400 and are fixedly connected to the pedal 400.

[0030] Also includes:

[0031] A connecting unit is provided between the motor 100 and the active linkage unit, which can realize the connection or disconnection between the motor 100 and the active linkage unit.

[0032] A transmission device for an electric side pedal includes an active drive mechanism and a driven drive mechanism disposed on both sides of the pedal 400 for driving the pedal 400 to automatically unfold or retract. A connection unit is provided between the active linkage unit and the motor 100, which can connect or disconnect the motor 100 and the active linkage unit. When the controller or motor 100 is damaged, or the circuit is disconnected and the electrical control part is not working, the pedal 400 can no longer automatically unfold or retract. At this time, the connection between the motor 100 and the active linkage unit can be disconnected through the connection unit to achieve manual reset or pull-out.

[0033] Preferably, the connecting unit includes a connecting shaft 200, which is detachably connected to the output shaft of the motor 100, and the active linkage unit is fixedly connected to the connecting shaft 200.

[0034] In this embodiment, the connecting unit includes a connecting shaft 200 that is detachably connected to the output shaft of the motor 100, and the active linkage unit is fixedly connected to the connecting shaft 200. Under normal use, the output shaft of the motor 100 is fixedly connected to the connecting shaft 200, and the motor 100 drives the active linkage unit to extend or retract the side pedal. When the motor 100 or the wiring is damaged, the connection between the motor 100 and the active linkage unit is disconnected, and manual reset or pull-out can be performed at this time.

[0035] Preferably, the connecting shaft 200 includes a hollow shaft, which is sleeved on the output shaft of the motor 100 and can rotate relative to the output shaft of the motor 100. The active linkage unit is fixed to the hollow shaft, and a locking unit is provided between the hollow shaft and the output shaft of the motor 100, so that the hollow shaft can rotate with the output shaft of the motor 100 or rotate relative to the output shaft of the motor 100.

[0036] In this embodiment, the connecting shaft 200 includes a hollow shaft, which is sleeved on the output shaft of the motor 100 and can rotate relative to the output shaft of the motor 100. A locking unit is provided between the hollow shaft and the output shaft of the motor 100, so that the hollow shaft can rotate with the output shaft of the motor 100 or rotate relative to the output shaft of the motor 100. Under normal use, the locking unit fixes the hollow shaft to the output shaft of the motor 100. The motor 100 drives the hollow shaft to drive the active linkage unit to realize the automatic unfolding or retraction of the pedal 400. When the motor 100 or the wiring is damaged, the connection between the hollow shaft and the output shaft of the motor 100 is disconnected through the locking unit. At this time, the side pedal can be manually unfolded or retracted, and then the locking unit can be locked to maintain the working state of the pedal 400, which is very convenient.

[0037] More preferably, the locking unit includes a locking nut 202, and a plurality of openings 201 are arranged circumferentially on the hollow shaft. An external thread is arranged around the hollow shaft at the position of the opening 201, and the locking nut 202 is screwed into the external thread.

[0038] Specifically, the multiple openings 201 arranged circumferentially on the hollow shaft are formed by cutting along the length of the hollow shaft, so that the part of the hollow shaft located at the opening 201 has a certain elasticity and can deform under the compression of the locking nut 202, thereby fixing the hollow shaft to the output shaft of the motor 100.

[0039] In this embodiment, the locking unit includes a locking nut 202. A plurality of openings 201 are arranged circumferentially on the hollow shaft. An external thread is arranged around the opening 201 on the hollow shaft. The locking nut 202 is screwed into the external thread. The hollow shaft can be fixed to the output shaft of the motor 100 by screwing the locking nut 202 into the external thread on the hollow shaft.

[0040] More preferably, a plurality of openings 201 are arranged circumferentially at the end of the hollow shaft away from the motor 100.

[0041] In this embodiment, multiple openings 201 are arranged circumferentially at the end of the hollow shaft away from the motor 100, which facilitates the locking and unlocking of the locking nut 202.

[0042] Preferably, the active linkage unit includes an active support 300 and a base frame 301. The active support 300 is fixed to the motor 100 and the vehicle, respectively. The base frame 301 is fixedly connected to the pedal 400. An inner connecting plate 302 and an outer connecting plate 303 are provided between the active support 300 and the base frame 301. Both ends of the outer connecting plate 303 are rotatably connected to the active support 300 and the base frame 301, respectively. One end of the inner connecting plate 302 is fixed to the connecting shaft 200, and the other end of the inner connecting plate 302 is rotatably connected to the base frame 301.

[0043] In this embodiment, the active linkage unit includes an active support 300 and a base frame 301. An inner connecting plate 302 and an outer connecting plate 303 are provided between the active support 300 and the base frame 301 to realize a four-bar linkage mechanism. The inner connecting plate 302 is fixedly connected to the hollow shaft. The motor 100 drives the hollow shaft to rotate, which in turn drives the inner connecting plate 302 to work. Through the mutual hinge between the inner connecting plate 302 and the outer connecting plate 303 and the active support 300 and the base frame 301 respectively, the pedal 400 is driven to automatically unfold or retract. When the motor 100 or the wiring is damaged, the connection between the hollow shaft and the output shaft of the motor 100 can be disconnected by loosening the locking nut 202. At this time, the pedal 400 can be manually unfolded or retracted, and then the locking nut 202 can be tightened to maintain the working state of the pedal 400, which is very convenient.

[0044] In this application, the structures of the driven linkage unit and the driving linkage unit are the same, and will not be described in detail here.
