[0021] 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.

[0022] A type of motorcycle pedal stand, such as Figures 1 to 4 As shown, the device includes a support body 1, and a front pedal mounting seat 2 is integrally formed at the front end of the support body 1. This can effectively enhance the structural strength of the connection between the front pedal mounting seat 2 and the support body 1, thereby effectively improving the fatigue resistance of the front pedal mounting seat 2.

[0023] In this embodiment, the front pedal mounting base 2 is U-shaped, and a front pedal mounting hole 3 is provided on the front pedal mounting base 2. The front pedal mounting hole 3 extends from one side of the front pedal mounting base 2 to the other side of the front pedal mounting base 2. The front pedal mounting hole 3 is used to cooperate with the pivot of the front pedal.

[0024] The front pedal mounting base 2 has a hollow groove 15, which can effectively reduce material consumption, reduce production costs and reduce weight. Moreover, the groove 15 structure can be used to match the corresponding structure on the frame, thereby achieving quick and accurate positioning, which facilitates the installation of the bracket body 1.

[0025] A torsion spring mounting hole 16 is provided at the bottom of the groove 15. The torsion spring mounting hole 16 passes through the front pedal mounting seat 2. That is, the end of the torsion spring is constrained and fixed through the torsion spring mounting hole 16 to ensure the stability of the torsion spring, thereby ensuring that the front pedal can be stably reset through the torsion spring.

[0026] The rear end of the support body 1 is integrally formed with a rear foot pedal mounting seat 4, which can effectively enhance the structural strength of the connection between the rear foot pedal mounting seat 4 and the support body 1, thereby effectively improving the fatigue resistance of the rear foot pedal mounting seat 4.

[0027] The bracket body 1 has a connecting hole 6, which passes through the rear pedal mounting seat 4. The rear pedal mounting seat 4 is fixedly connected to the frame by fasteners that fit into the connecting hole 6. The fasteners are preferably bolts. By connecting the frame with the frame through the connecting hole 6, the stability of the bracket body 1 can be further improved. Moreover, by using this connection point as an auxiliary fixing point for the rear pedal mounting seat 4, the load is distributed to this auxiliary fixing point when the rear pedal mounting seat 4 is under force. This avoids all the load being concentrated at the connection between the rear pedal mounting seat 4 and the bracket body 1, which would form a significant stress concentration. This improves the fatigue resistance of the rear pedal mounting seat 4 and reduces the risk of cracks and eventual breakage at the connection between the rear pedal mounting seat 4 and the bracket body 1 due to metal fatigue.

[0028] In this embodiment, the rear pedal mounting base 4 is U-shaped, and a rear pedal mounting hole 5 is provided on the rear pedal mounting base 4. The rear pedal mounting hole 5 extends from one side of the rear pedal mounting base 4 to the other side of the rear pedal mounting base 4, and is used to cooperate with the rotating shaft of the rear pedal.

[0029] The support body 1 has a weight reduction hole 13 in the middle and a weight reduction hole 14 at the rear end. By opening the weight reduction hole 13 and the weight reduction hole 14, the consumables required for the production of the support body 1 are reduced, thereby reducing the production cost of the support body 1 and reducing the weight of the support body 1.

[0030] The bracket body 1 has a fork mounting hole 7 and at least three spaced fixing holes 8. The three fixing holes 8 surround the outside of the fork mounting hole 7 and are arranged in a triangular structure. The bracket body 1 is fixedly connected to the frame by the fixing holes 8 and corresponding fasteners. The triangular structure of the three fixing holes 8 can effectively enhance the stability of the connection structure due to the stability of the triangular structure. Furthermore, since the three fixing holes 8 surround the outside of the fork mounting hole 7, the stability of the position of the fork mounting hole 7 can be further improved.

[0031] The bracket body 1 has several reinforcing protrusions 9 integrally formed, and several fixing holes 8 pass through the corresponding reinforcing protrusions 9. The bracket body 1 also has several reinforcing ribs 10 integrally formed, and the reinforcing ribs 10 extend outward from the side wall of the reinforcing protrusions 9. This not only ensures the structural strength of the area around the fixing holes 8, but also effectively improves the overall structural strength of the bracket body 1.

[0032] The front end of the bracket body 1 is provided with a reserved through hole 11. The reserved through hole 11 can be used for the rope to pass through or to install other components according to actual needs, thereby increasing the functionality of the motorcycle. The bracket body 1 is integrally formed with a reinforcing protrusion 12. The reserved through hole 11 passes through the reinforcing protrusion 12. The reinforcing protrusion 12 can effectively ensure the structural strength of the area around the reserved through hole 11, and can also effectively improve the overall structural strength of the bracket body 1.

[0033] A bushing 17 is provided inside the connection hole 6. The fastener passes through the bushing 17. The bushing 17 consists of an inner sleeve layer 171, a rubber layer 172, and an outer sleeve layer 173 from the inside to the outside.

[0034] It should be noted that when the vehicle is in motion, the pedals will be subjected to forces from different directions (pedaling force, lateral force and vibration), which will be transmitted to the bracket body 1. At this time, the middle rubber layer 172 absorbs and buffers these forces and vibrations through its own elastic deformation properties.

[0035] Furthermore, the outer sidewall of the inner sleeve 171 and the inner sidewall of the outer sleeve 173 both have positioning protrusions 174, and the inner sidewall and the outer sidewall of the rubber layer 172 both have positioning grooves 175 that are adapted to the positioning protrusions 174. The positioning protrusions 174 are located in the positioning grooves 175. Through the cooperation between the positioning protrusions 174 and the positioning grooves 175, the bond between the inner sleeve 171 and the outer sleeve 173 and the rubber layer 172 is made stronger during the vulcanization process of the inner sleeve 171 and the outer sleeve 173 and the rubber layer 172.

[0036] Both the front pedal mounting hole 3 and the rear pedal mounting hole 5 are countersunk holes. The outer edges of both the front pedal mounting hole 3 and the rear pedal mounting hole 5 are provided with arc-shaped guide surfaces 18. The countersunk step edges of both the front pedal mounting hole 3 and the rear pedal mounting hole 5 are provided with arc-shaped guide surfaces 19. Both arc-shaped guide surfaces 18 and 19 are used to guide the lubricant.

[0037] Specifically, when adding lubricant, the lubricant is dripped onto the corresponding arc-shaped guide surface 18. Guided by the arc-shaped guide surface 18, the lubricant flows to the countersunk step surface of the front pedal mounting hole 3 or the rear pedal mounting hole 5 corresponding to the arc-shaped guide surface 18. The lubricant on the countersunk step surface of the front pedal mounting hole 3 or the rear pedal mounting hole 5 continues to penetrate into the front pedal mounting hole 3 or the rear pedal mounting hole 5 under the guidance of the corresponding arc-shaped guide surface 19, so that the lubricant can effectively contact the pivot of the front pedal or the pivot of the rear pedal, thereby achieving the lubrication effect on them.

[0038] An epoxy lubricating wear-resistant coating 20 is provided on the contact surface between the front pedal mounting seat 2 and the front pedal, and on the contact surface between the rear pedal mounting seat 4 and the rear pedal, thereby further improving the wear resistance of the front pedal mounting seat 2 and the rear pedal mounting seat 4, and also reducing the possibility of the front pedal or the rear pedal getting stuck.

[0039] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
