[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the vehicle door moves, the driving module drives each of the pedal supports to drive the pedal body to move horizontally in the transverse direction. When the vehicle door is opened and closed, the driving module 1 of the present invention drives the pedal body 2 to perform linear expansion and contraction in the transverse direction.

[0049] An electric pedal in an embodiment of the present invention includes a drive module, a pedal body and at least two pedal supports. When a vehicle door is opened and closed, the drive module of the present invention drives the pedal body to perform a linear motion in the lateral direction to expand and contract, thereby reducing the complexity of the expansion and contraction movements of the electric pedal. The electric pedal does not produce position changes in the height direction, thereby reducing the risk of touching obstacles under the vehicle chassis and reducing usage restrictions. At the same time, the electric pedal is completely hidden under the bottom of the vehicle body in the contracted state, and is not visible from the outside, which is more conducive to beautifying the appearance of the vehicle.

[0050] As an optional implementation, in an embodiment of the invention, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the driving module 1 is provided with a controller 11, a driving motor 12 and a transmission assembly 13. The controller 11 is provided on the vehicle body, the driving motor 12 is provided at the bottom of the vehicle body, the driving motor 12 is electrically connected to the controller 11, and the transmission assembly 13 is connected to the driving motor 12 and the pedal support 3. When the door moves, the door lock switch of the door outputs a door opening / closing signal to the controller 11, and the controller 11 obtains the door opening / closing signal. At this time, the controller 11 determines that the driver is about to get on or off the vehicle, and the controller 11 outputs an action signal to the driving motor 12, so that the driving motor 12 drives the transmission assembly 13 to drive the pedal body 2 to move laterally along the setting direction of the pedal support 3. The driving module of the embodiment of the present invention has a stable structure and high reliability.

[0051] As an optional implementation, in an embodiment of the invention, see Figure 1 As shown, the drive motor 12 is longitudinally arranged on the pedal support 3 at one end away from the pedal body 2, and the drive motor 12 is arranged parallel to the pedal body 2, which reduces the space occupied by the electric pedal in the lateral direction and is beneficial to the arrangement of the bottom components of the vehicle.

[0052] As an optional implementation, in an embodiment of the invention, see Figure 2 , Figure 3 and Figure 4As shown, the transmission assembly 13 is provided with an upper transmission part 131 and a lower transmission part 132, the upper transmission part 131 is connected to the rotor of the driving motor 12, the lower transmission part 132 is arranged inside the pedal support 3, the upper transmission part 131 is meshed with the lower transmission part 132, in the embodiment of the present invention, the driving motor 12 and its rotor are arranged in the longitudinal direction, in order to realize driving the pedal body 2 to move in the transverse direction, the upper transmission part 131 and the lower transmission part 132 are adopted in a spatially staggered manner, and the upper transmission part 131 is meshed with the lower transmission part 132, so that the rotor arranged in the longitudinal direction sequentially drives the upper transmission part 131, the lower transmission part 132 and the pedal body 2, and finally realizes driving the pedal body 2 to move in the transverse direction. The transmission is carried out by adopting the upper transmission part and the lower transmission part in a spatially staggered manner, the structure is compact, and the space occupied by the electric pedal is reduced. Compared with the traditional four-bar linkage, the space occupied by the embodiment of the present invention is reduced by 50%.

[0053] As an optional implementation, in an embodiment of the invention, see Figure 2 and Figure 3 As shown, the upper transmission part 131 is provided with a worm gear 1311, a driven rod 1312 and a screw driving tooth 1313, the worm of the worm gear 1311 is connected to the rotor of the drive motor 12, the rotor drives the worm of the worm gear 1311 to rotate, and the worm drives the worm wheel to rotate, the driven rod 1312 is arranged in the horizontal direction, the driven rod 1312 is connected to the worm wheel of the worm gear 1311, the worm wheel drives the driven rod 1312 to rotate, the screw driving tooth 1313 is connected to the driven rod 1312, and the driven rod 1312 drives the screw driving tooth 1313 to rotate back and forth, thereby the rotational motion of the drive motor 12 drives the worm gear 1311 through the rotor to reduce the motion of the rotor and convert it into the rotational motion of the driven rod 1312 crossed by 90°. The upper transmission part formed by the worm gear, the driven rod and the lead screw driving teeth in the embodiment of the present invention has a compact structure and high stability, thereby improving the transmission reduction ratio under high-speed driving of the driving motor.

The lead screw 1321 is arranged laterally inside the pedal support 3, and the lead screw driven tooth 1322 is arranged at the end of the lead screw 1321 away from the pedal body 2. The lead screw driven tooth 1322 is meshed with the lead screw driving tooth 1313. The two lead screw bearings 1323 are both arranged at one end of the lead screw 1321 close to the pedal body 2, each of the lead screw bearings 1323 is movably connected to the lead screw 1321, and each of the lead screw bearings 1323 is detachably connected to the pedal support 3. In the embodiment of the present invention, one end of the lead screw 1321 is connected to the pedal support 3 through the two lead screw bearings 1323, and the other end is installed on the support of the drive motor 12 through a fixed bearing. The rotational motion of the rotor of the drive motor 12 is further reduced by the cooperation between the lead screw driving teeth 1313 and the lead screw driven teeth 1322, and the lead screw 1321 is driven to rotate by the lead screw driven teeth 1322. When the lead screw 1321 is driven to rotate by the lead screw driven teeth 1322, the lead screw 1321 itself only performs rotational motion due to the limitation of the support of the drive motor 12. When the lead screw 1321 performs rotational motion, the thread inside the lead screw bearing 1323 that meshes with the lead screw 1321 converts the axial rotation of the lead screw bearing 1323 into the linear motion of the lead screw bearing 1323, and the linear motion is along the extension direction of the lead screw 1321. In the embodiment of the present invention, the lower transmission part has a compact structure and high transmission stability, and the transmission reduction ratio under high-speed driving of the drive motor is further improved.

[0055] As an optional implementation, in an embodiment of the invention, see Figure 4 As shown, each of the pedal supports 3 is provided with a seat plate 31 and a screw support seat 32. The seat plate 31 is laterally arranged below the pedal body 2, one end of the seat plate 31 is connected to the pedal body 2, and the screw support seat 32 is arranged in the middle part of the seat plate 31. The screw support seat 32 is adapted to the shape of the screw bearing 1323, and the screw bearing 1323 is arranged inside the screw support seat 32. When the screw bearing 1323 moves linearly along the screw 1321, it drives the screw support seat 32 and the seat plate 31 to move linearly. The seat plate and the screw support seat have stable structures, which improves the reliability of the electric pedal.

[0056] As an optional implementation, in an embodiment of the invention, see Figure 4 As shown, the screw support seat 32 is a top-opening structure, and the screw support seat 32 with a top-opening structure is convenient for timely replacement and maintenance of the internal screw bearing.

In an embodiment of the present invention, the fastener 33 is a fastening nut, and the fastener 33 fixes the pedal body 2 to the seat plate 31, which facilitates disassembly while improving the stability of the electric pedal.

[0058] An electric pedal in an embodiment of the present invention has the following working principle:

[0059] When the controller 11 obtains the signal of the door opening / closing action, the controller 11 determines the user's intention based on the current vehicle state and the current state of the pedal body 2. When the vehicle is stopped, the gear is in the P / N gear, the vehicle is unlocked, and any door is opened or closed, the controller 11 determines that the user is about to get on or off the vehicle, and the controller 11 gives a current signal to the drive motor 12. After the drive motor 12 receives the current signal, the drive motor 12 performs a rotational motion. The rotational motion of the drive motor 12 is converted into a rotational motion of a driven rod 1312 that crosses 90 degrees by driving the worm gear 1311 through the rotor. The driven rod 1312 is installed on the support of the drive motor 12, and the driven rod 1312 is integrated with a lead screw drive tooth 1313. The lead screw driving teeth 1313 and the lead screw driven teeth 1322 are in a matching meshing relationship with each other. The rotational motion of the rotor of the driving motor 12 is further decelerated by the cooperation between the lead screw driving teeth 1313 and the lead screw driven teeth 1322, and the lead screw 1321 is driven to rotate by the lead screw driven teeth 1322. A lead screw bearing 1323 is installed on the lead screw 1321, and the lead screw bearing 1323 matches the lead screw support seat 32 and is arranged in the lead screw support seat 32. When the lead screw 1321 rotates, the lead screw bearing 1323 is driven to move linearly along the axis of the lead screw 1321 through the thread between the lead screw 1321 and the lead screw bearing 1323. The lead screw bearing 1323 is fastened to the seat plate 31 of the pedal support 3 through the lead screw support seat 32 to form an integral body, so the rotation of the lead screw 1321 drives the lead screw bearing 1323 to make a linear motion along the axis of the lead screw 1321 through the thread between the lead screw 1321 and the lead screw bearing 1323, thereby driving the pedal support 3 to make a linear motion. The pedal support 3 is connected to the pedal body 2, so the rotation of the lead screw 1321 is converted into a linear motion of the pedal body 2, thereby realizing the lateral horizontal linear motion of the pedal body 2.

[0069] An electric pedal and a car in an embodiment of the present invention have the following working principles:

[0070] When the controller 11 obtains the signal of the door opening / closing action, the controller 11 determines the user's intention based on the current vehicle state and the current state of the pedal body 2. When the vehicle is stopped, the gear is in the P / N gear, the vehicle is unlocked, and any door is opened or closed, the controller 11 determines that the user is about to get on or off the vehicle, and the controller 11 gives a current signal to the drive motor 12.
