[0034] Referring to Figure 1-8 , an electric swing arm structure for an automotive electric pedal according to an embodiment of the present utility model includes: a motor 1, a rotating shaft 7, a bottom plate 8, and a swing arm 12. Among them, the rotating shaft 7 is installed on the bottom plate 8 and is rotatably connected to the bottom plate 8; the motor 1 is installed on the top of the bottom plate 8, and the motor shaft 6 of the motor 1 cooperates with the top of the rotating shaft 7 to drive the rotating shaft 7 to rotate; the swing arm 12 is arranged at the bottom of the bottom plate 8 and is fixedly connected to the bottom of the rotating shaft 7, so that the rotating shaft 7 can drive the swing arm 12 to rotate.
[0035] The motor shaft 6 of the motor 1 has two first mounting planes 101, and the two first mounting planes 101 are arranged in parallel. The top of the rotating shaft 7 has a motor shaft mounting groove 701, and the shape of the motor shaft mounting groove 701 is adapted to the motor shaft 6 of the motor 1, so that the motor shaft 6 of the motor 1 can be inserted into the motor shaft mounting groove 701 and can drive the rotating shaft 7 to rotate. The bottom plate 8 is provided with two front and rear limit hooks corresponding to the hook positions in the extended and retracted states of the swing arm 12.
[0036] Specifically in this embodiment, the motor 1 drives the swing arm 12 to rotate through the rotating shaft 7, and the swing arm 12 can drive the electric pedal of the vehicle to expand and contract, facilitating the user to step on. The connection method between the motor 1 and the rotating shaft 7 in this embodiment is different from the prior art. The motor 1 and the rotating shaft 7 do not need to be connected by screws. During assembly, the motor shaft 6 is inserted into the motor shaft mounting groove 701. The motor shaft 6 and the motor shaft mounting groove 701 adopt planar limit fit, and the torque of the motor shaft 6 can be transmitted to the rotating shaft 7. By using this flat position insertion connection method, the process is simple, the disengagement risk is small, the production cost is low, and there is no risk of failure caused by screws.
[0037] In some embodiments, referring to Figure 7, the motor shaft mounting groove 701 has two relatively arranged planar structures and two relatively arranged arc-shaped structures. The planar structure and the arc-shaped structure are adjacent. The planar structure is adapted to the first mounting plane 101, and the arc-shaped structure is adapted to the outer cylindrical surface of the motor shaft 6 of the motor 1. The torque of the motor 1 can be transmitted through the planar fit.
[0038] In some embodiments, referring to Figure 6 , the bottom plate 8 has a rotating shaft cover for mounting the rotating shaft 7. A rotating shaft cover plate 3 is provided at the top of the rotating shaft 7. The rotating shaft cover plate 3 is fixedly installed on the bottom plate 8 to limit the axial displacement of the rotating shaft 7. The rotating shaft 7 is installed in the rotating shaft cover, and the rotating shaft cover and the rotating shaft cover plate 3 function to prevent the rotating shaft 7 from moving along its axial direction.
[0039] In some embodiments, referring to Figure 6 , a second sealing ring 4 is provided between the rotating shaft cover plate 3 and the bottom plate 8. The second sealing ring 4 functions as a seal, and the second sealing ring 4 can prevent dust and water from entering the rotating shaft 7.
[0040] In some embodiments, referring to Figure 3 , the top of the rotating shaft 7 is rotatably connected to the bottom plate 8 through a first bearing 5, and the bottom of the rotating shaft 7 is rotatably connected to the bottom plate 8 through a second bearing 9. The first bearing 5 is installed above the rotating shaft 7, and the second bearing 9 is sequentially inserted through a gasket and a second bearing 9 below. The upper and lower double bearings make the rotation of the rotating shaft 7 smoother and maintain better coaxiality.
[0041] In some embodiments, a third sealing ring 10 is provided between the bottom of the rotating shaft 7 and the bottom plate 8. The third sealing ring 10 can be a star-shaped sealing ring. The star-shaped sealing ring is installed in the groove of the rotating shaft 7 to prevent water and sand from entering the rotating mechanism from below the rotating shaft 7.
[0042] In some embodiments, referring to Figure 7 , the motor 1 is installed on the bottom plate 8 through the rotating shaft cover plate 3. A first sealing ring 2 is provided between the motor 1 and the rotating shaft cover plate 3. The motor 1 is fixed to the rotating shaft cover plate 3 by bolts. The motor 1 is installed in a hidden manner above the bottom plate 8 and is not easily damaged by collision during the driving process.
[0043] In some embodiments, referring to Figure 8, the bottom of the rotating shaft 7 has two parallel mating planes, the rocker arm 12 has a fixing groove adapted to the bottom of the rotating shaft 7, and the bottom of the rotating shaft 7 is installed in the fixing groove. Specifically, the rocker arm 12 is provided with a limiting hook to limit the positions of the extension and contraction of the rotating mechanism. There are grooves on both sides of the limiting hook for installing anti-collision rubber to reduce the limiting noise. One end of the rocker arm 12 is provided with through holes for installing two upper and lower bushings to make the rotation of the pedal bracket smoother and reduce noise. The other end of the rocker arm 12 is provided with a flat position for connecting with the rotating shaft 7. Similarly, the rotating shaft 7 and the rocker arm 12 adopt plane limit fit, which can make the rotating shaft 7 drive the rocker arm 12 to rotate synchronously. The flat position is used for plug-in connection, with simple process, small disengagement risk and low production cost.
[0044] In some embodiments, the rocker arm 12 is fixedly connected to the rotating shaft 7 by screws 11. The screws 11 pass through the middle of the rotating shaft 7, and other fixing methods can also be selected.
