[0046] The side pedal is installed below the door side of a medium or large vehicle to facilitate people to get on and off the vehicle. In view of the problem of insufficient stability of the existing electric side pedal, an electric side pedal with high stability and a vehicle are provided.

[0047] The high-stability electric side pedal and the vehicle of the present application will be described in detail below through the following embodiments.

[0048] Embodiment one:

[0049] As shown in the figure, the embodiment provides a high-stability electric side pedal, which comprises: a pedal body 1; two groups of telescopic assemblies 2, which are respectively located on both sides of the pedal body 1 and are used to connect the pedal body 1 with the lower side of the door of the vehicle; and a driving part 3, which is used to apply an external force to the pedal body 1 to move the pedal body 1 along the telescopic path of the telescopic assembly 2.

[0050] Among them, the driving part 3 is an electric support rod, one end of which is connected with the pedal body 1, and the other end of which is connected with the bottom of the vehicle.

[0051] The pedal body 1 is assembled on the bottom of the vehicle through the two groups of telescopic assemblies 2, and is driven by the driving part 3 to perform telescopic movement, so that the pedal body 1 can be extended outward from the bottom of the vehicle or be retracted inward. Specifically, the pedal body 1 is applied with outward pushing force or inward pulling force by the electric support rod, so that the pedal body 1 is extended outward or retracted inward. At present, the electric support rod is commonly used in the tail door of the vehicle, so that the tail door of the vehicle can be automatically opened or closed. In the present embodiment, the electric support rod is applied to the side pedal, not only realizing the automatic telescoping of the side pedal and being convenient to control, but also making the pedal body 1 more stable during movement and occupying less space in height (the electric support rod tends to be installed horizontally, while the motor needs to have a larger reserved space in the height direction), so that the installation is more convenient.

[0052] It should be noted that the electric support rod is rotatably connected with the bottom of the pedal body 1 through the ball joint thereon. In order to improve the uniformity of the stress, the electric support rod is connected with the middle part of the bottom of the pedal body 1.

[0053] It should be noted that the thrust of the electric support rod can be designed according to the actual situation, and the design range can be 1000N to 3000N. Of course, if a larger thrust is required, the electric support rod can be further optimized.

[0054] Example two:

[0055] This embodiment is a further improvement based on example one.

[0056] As shown in the figure, in this embodiment, the pedal body 1 includes: a pedal framework 11, which has a first anti-skid strip 111 extending along the length direction thereof; a front protective cover plate 12, which is arranged at the front end of the pedal framework 11 and covers part of the upper and lower surfaces of the pedal framework 11; and side protective cover plates 13, which have two, respectively arranged on both sides of the pedal framework 11 and cover both ends of the pedal framework 11.

[0057] Among them, the front protective cover plate 12 is also provided with a decorative plate 14, and the part of the decorative plate 14 above the front protective cover plate 12 forms a second anti-skid strip 141.

[0058] The pedal body 1 is the main structure of the side pedal, which mainly includes the pedal framework 11, the front protective cover plate 12 and the side protective cover plates 13. The pedal framework 11 is the main stress structure, which has a triangular cross section and can be made of high-strength plastic injection molding or aluminum alloy material processing. In order to ensure the weight of the pedal framework 11, the inside of the pedal framework 11 can be hollow. The front protective cover plate 12 is mainly used for protecting the front side of the pedal framework 11 to reduce the deformation of the pedal framework 11 after being hit. The side protective cover plates 13 are used for protecting both sides of the pedal framework 11. Since the pedal framework 11 is hollow, the side protective cover plates 13 are arranged to prevent foreign matter from entering the pedal framework 11.

[0059] In order to avoid slipping when people step on the pedal framework 11, the first anti-skid strip 111 is formed on the pedal framework 11, which protrudes upward and is integrally formed with the pedal framework 11, which not only improves the strength of the entire pedal framework 11, but also has the effect of preventing slipping. When people step on the pedal framework 11, the front protective cover plate 12 is also stepped on. In order to improve the anti-skid effect, the decorative plate 14 is also arranged, and the second anti-skid strip 141 is formed on the decorative plate 14.

[0060] It should be noted that since the side step plate gradually moves outward when it is extended outward, the front side of the step frame 11 is at risk of being hit, so the front protective cover plate 12 is arranged on the front side of the step frame 11 and covers the front side of the step frame 11. After covering, it can be fixed on the step frame 11 by bolts and the like.

[0061] Regarding the side protective cover plate 13, it can be installed on both sides of the step frame 11 in a plug-in manner, and then fixed by bolts.

[0062] In this embodiment, the first anti-skid strip 111 is optimized to have multiple strips and is arranged at intervals along the width direction of the step frame 11; the height of the second anti-skid strip 141 is lower than that of the first anti-skid strip 111. By arranging multiple first anti-skid strips 111 to improve the anti-skid effect, the first anti-skid strip 111 and the second anti-skid strip 141 are arranged to have a certain height gradient to disperse the stepping force and further improve the anti-skid performance.

[0063] In this embodiment, the first supporting pad 15 is arranged between the front protective cover and the step frame 11; the second supporting pad 16 is arranged between the front protective cover plate 12 and the decorative plate 14. The first supporting pad 15 and the second supporting pad 16 can be made of rubber material to have a certain buffering effect after being subjected to the stepping force.

[0064] Specifically, the first supporting pad 15 and the second supporting pad 16 are both in strip structure, and the front protective cover plate 12 is a sheet metal structure, the upper end of which has at least two protruding convex strips arranged at intervals, the lower ends of the two convex strips form a first concave groove, the first supporting pad 15 is installed in the first concave groove, and the depth of the first concave groove is smaller than the thickness of the first supporting pad, so that the first supporting pad still protrudes downward after being installed in the first concave groove, and the protruding part can play a role of force buffering. The second concave groove is formed between the two convex strips, and the second supporting pad 16 is installed in the second concave groove, and then the decorative plate 14 covers the second supporting pad 16. Similarly, the thickness of the second supporting pad 16 is greater than the depth of the second concave groove.

[0065] It should be noted that the two ends of the decorative plate 14 can extend out of the front protective cover plate 12, and the extended part is covered by the side protective cover plate 13. In this way, the fixing of the decorative plate is reduced. After the decorative plate is placed in the second concave groove on the front protective cover plate 12, the two side protective cover plates 13 can limit the decorative plate, and finally only the side protective cover plates 13 need to be fixed by bolts to realize the fixing of the decorative plate.

[0066] Embodiment three:

[0067] This embodiment is a further improvement based on any of the above embodiments.

[0068] As shown in the figure, in the embodiment, the telescopic assembly 2 comprises a mounting base 21 arranged at the bottom of the vehicle, two mounting side plates 211 arranged downward on both sides of the mounting base 21, a telescopic arm 22 connected to the pedal body 1 at one end, a first swing arm 23 rotatably arranged between the two mounting side plates 211 at one end and rotatably arranged with the telescopic arm 22 at the other end, and a second swing arm 24 rotatably arranged between the two mounting side plates 211 at one end and rotatably arranged with the telescopic arm 22 at the other end.

[0069] The mounting base 21, the telescopic arm 22, the first swing arm 23 and the second swing arm 24 form a four-bar mechanism, and after the pedal body 1 is subjected to an external force applied by the electric support rod, the pedal body 1 moves along the telescopic path of the four-bar mechanism.

[0070] The mounting base 21 is fixed on the bottom of the vehicle by bolts, and when the pedal body 1 is subjected to an external force of the electric support rod, the telescopic arm 22 and the pedal body 1 move synchronously, and the telescopic arm 22 and the pedal body 1 move along the set telescopic path through the first swing arm 23 and the second swing arm 24, and when the telescopic arm 22 is extended to the farthest position, the upper end surface of the pedal body 1 tends to be flat and can be slightly inclined upward by a certain angle.

[0071] In the embodiment, the telescopic arm 22 is optimized and comprises a telescopic arm body 221 connected to the pedal body 1, and two connecting arms 222 arranged on both sides of the telescopic arm body 221, and the first swing arm 23 and the second swing arm 24 are rotatably arranged between the two connecting arms 222.

[0072] The two connecting arms 222 are provided with an extension section 223 extending upward, and when the telescopic arm body 221 is in the retracted state, the lower ends of the two mounting side plates 211 abut against the upper ends of the extension sections 223 of the two connecting arms 222.

[0073] At present, when the pedal body 1 is retracted inward, the first swing arm 23 and the second swing arm 24 swing, and when they abut against each other, it indicates that the pedal body 1 is retracted to the innermost position. This design is prone to cause loosening of the first swing arm 23 and the second swing arm 24, and therefore the connecting arm 222 on the telescopic arm 22 is improved in the embodiment, and the extension section 223 extending upward is arranged on the connecting arm 222. On the one hand, the extension section 223 is limited by the abutment of the mounting side plate 211 and the extension section 223, which effectively avoids the loosening of the first swing arm 23 and the second swing arm 24. On the other hand, the design of the extension section 223 can effectively improve the strength of the connecting arm 222, so that it is not easy to break.

[0074] It should be noted that the upper end surface of the extension section 223 is inclined, and the connection between the extension section 223, the telescopic arm body 221 and the connecting arm 222 is transitioned by a circular arc.

[0075] In the embodiment, the first swing arm 23 and the second swing arm 24 are both arc-shaped plate structures, and the concave arc surface of the first swing arm 23 and the concave arc surface of the second swing arm 24 are opposite. The first swing arm 23 and the second swing arm 24 are provided in the arc-shaped plate structure, so that the first swing arm 23 and the second swing arm 24 have higher load capacity and are not easy to bend or break.

[0076] Embodiment four:

[0077] The embodiment provides a vehicle, which comprises a vehicle body and a high-stability electric side step according to any one of the above-mentioned embodiments, wherein the high-stability electric side step is arranged at the bottom side of the vehicle body.

[0078] The above has described the embodiments of the present disclosure, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles, practical application, or improvement of the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
