[0002] With the development of economy, consumers have higher and higher requirements for the appearance of motorcycles. In order to achieve better appearance consistency and overall effect, the footrests of rear passengers on motorcycles are designed to be hidden. The footrests are hidden inside the plastic parts of the vehicle body and need to be manually operated to open when in use. However, the gap between the plastic parts of the vehicle body and the footrests is very small, and there is insufficient space for manual operation to open the footrest, making the operation difficult and very inhumane. There are also some pressing auxiliary devices provided inside the plastic parts of the vehicle body. However, when the motorcycle is traveling at high speed and encounters roads with more mud and gravel, the splashing mud and gravel are easily introduced into the auxiliary device, resulting in the failure of popping out.

Detailed implementation manners

[0022] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0023] As Figures 1 to 6 shown, a push-type footrest device includes a footrest board 3 and an ejection mechanism. The ejection mechanism includes a connecting plate 2, a sealing base 21, a moving limiting pin 8, and a pressing cap 12. One side of the connecting plate 2 is provided with a sealing base 21 and a sleeve 16. A pin hole is formed on one side of the sealing base 21 close to the sleeve 16. A moving limiting pin 8 is arranged inside the sealing base 21. A first spring 9 is arranged between one end of the moving limiting pin 8 and the inner wall of the sealing base 21. The other end of the moving limiting pin 8 passes through the pin hole and faces the side of the sleeve 16. An opening hole 8a is formed in the middle of the moving limiting pin 8. The side of the opening hole 8a close to the first spring 9 is set as a first inclined surface. A pressing through hole is formed on the outer side of the sealing base 21. A pressing cap 12 is assembled in the pressing through hole. A second spring 14 is arranged between the pressing cap 12 and the sealing base 21. The second spring 14 pushes the pressing cap 12 outwards. An ejector rod 12a is arranged inside the pressing cap 12. The side of the ejector rod 12a close to the first spring 9 is set as a second inclined surface, forming a wedge-shaped ejector rod 12a. The ejector rod 12a is opposite to the opening hole 8a. The second inclined surface of the ejector rod 12a and the first inclined surface inside the opening hole 8a are arranged oppositely. One end of the footrest board 3 is set as a mounting end 3a. A mounting through hole is formed in the mounting end 3a. The sleeve 16 is arranged in the mounting through hole. A torsion spring 7 is arranged between the sleeve 16 and the mounting through hole. A limiting groove 3b is formed on the side of the mounting end 3a away from the footrest board 3. Under the pressure of the first spring 9, the moving limiting pin 8 can pass through the pin hole and be inserted into the limiting groove 3b.

[0024] Specifically, a pressing card slot is provided outside the ejector rod 12a inside the pressing cap 12. A card spring 13 is assembled in the pressing card slot. The card spring 13 is located inside the sealing base 21. The outer diameter of the card spring 13 is greater than the inner diameter of the pressing through hole. Its function is to limit the pressing cap 12 inside the sealing base 21 when it is static, playing a limiting role. Of course, a limiting ring or a limiting post can also be provided inside the sealing base 21 to limit the card spring 13 inside it and prevent the pressing cap 12 from popping out.

[0025] Specifically, a receiving cavity 3c is provided at one end of the mounting through hole of the mounting end 3a. The torsion spring 7 is placed in the receiving cavity 3c. A first card slot 3d is provided on the side wall of the receiving cavity 3c. One end of the torsion spring 7 is inserted into the first card slot 3d. A second card slot 17a is provided on the side wall of the sleeve 17. The other end of the torsion spring is inserted into the second card slot 17a.

[0026] Specifically, it further includes a mounting bracket 1. An upper mounting plate 17 and a lower mounting plate 18 are provided on one side of the mounting bracket 1. The pop-up mechanism is assembled between the upper mounting plate 17 and the lower mounting plate 18, which is convenient for installation and can be directly replaced on some existing motorcycles.

[0027] Specifically, a first mounting hole 2a is provided on the connecting plate 2 corresponding to the position of the sleeve 16. Second mounting holes and third mounting holes are respectively provided on the upper mounting plate 17 and the lower mounting plate 18 corresponding to the position of the sleeve 16. The connecting bolts sequentially pass through the second mounting hole, the first mounting hole 2a, the through hole of the sleeve 16, and the third mounting hole, and are fixed with a self-locking nut 5, which can make the shaking amount of the outermost end of the footrest 3 up and down not exceed ±1 mm, so as to ensure that when the footrest 3 is retracted, it can be smoothly hidden into the plastic cover of the vehicle body.

[0028] Specifically, a POM gasket is provided outside the torsion spring 7 in the receiving cavity 3c. The torsion spring 7 is restricted in the receiving cavity 3c by using the lower mounting plate 17 or a bolt, ensuring that the limiting end of the torsion spring 7 does not come out of the receiving cavity 3c under any circumstances, sealing the movement space of the torsion spring 7, preventing gravel and sand particles from entering, avoiding the failure of the torsion spring 7 to operate, and avoiding the situation where the footrest 3 cannot automatically pop up.

[0029] Specifically, one side surface of the sealing base 21 is set as an opening, and a sealing cover plate 10 is provided at the opening. The sealing cover plate 10 is assembled on the wall of the sealing base 21 through a cover plate bolt 11, which is convenient for assembling the internal moving limit pin 8 and the first spring 9. While being convenient for assembly, the sealing cover plate 10 seals the sealing base 21 to protect internal components such as the first spring 9, the second spring 14, the ejector rod 12a, and the moving limit pin 8, preventing gravel and sand particles from entering during the running of the motorcycle and causing the slider to get stuck and the footrest 3 to be unable to automatically pop up.

[0030] Specifically, a rubber pad 15 is provided on one side of the sealing base 21 close to the sleeve, which greatly reduces the noise generated when the footrest 3 pops out to the use position and impacts the sealing base 21.

[0031] Specifically, a limit post 19 is provided above the connecting plate 2, and an L-shaped or C-shaped limit sliding hole 20 is provided on the side of the upper mounting plate 17 away from the bracket 1. The limit post 19 enters the limit sliding hole 20 from the opening of the limit sliding hole 20, playing a certain role in fixing and limiting, facilitating the assembly of the connecting bolt 4, and also playing a role in limiting the left and right positions during the later use process.

[0032] Its working principle is as follows: When the footrest 3 is not in use, under the elastic force of the second spring 14, the ejector rod 12a of the pressing cap is located outside the opening hole 8a of the movable limit pin 8. Under the pressure of the first spring 9, the movable limit pin 8 can pass through the pin hole and be inserted into the limit groove 3b outside the mounting end 3a of the footrest 3, restricting the elastic force of the torsion spring 7 at the mounting end, and thus restricting the position of the footrest 3.

[0033] When the footrest 3 needs to be used, a force is applied to the pressing cap 12 with the foot. The second inclined surface of the ejector rod 12a of the pressing cap 12 gradually squeezes the first inclined surface of the opening hole 8a inward, causing the movable limit pin 8 to press against the first spring 9, overcoming the pressure of the first spring 9, and moving the movable limit pin 8 from the mounting end 13a of the footrest 13. When the movable limit pin 8 leaves the limit groove 3b of the footrest 3, under the elastic force of the torsion spring 7, the footrest 3 unfolds for the use of the passenger on the rear seat of the motorcycle.

[0034] The present invention is not limited to the described embodiments. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
