AI Technical Summary
The existing motorcycle backrest flip structure is prone to damage to the contact surface due to excessive stress during positioning.
A flip mechanism on the backrest of the motorcycle is designed to restrict the flip of the flipped seat by cooperating with the limiting pin and the arc-shaped groove to prevent direct contact and abutment of the flipped seat from the motorcycle lifting seat.
It effectively avoids collision between the flipped seat and the motorcycle lift seat, reduces the risk of damage, and makes it less likely to cause damage during use.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of motorcycle backrests, in particular to a turning mechanism on a motorcycle backrest. Background Art
[0002] At present, motorcycles are a relatively common means of transportation. In order to facilitate the support of the rider or passengers, a backrest is generally installed at the rear of the motorcycle. The backrest is generally a flip structure. When positioning, the existing flip structure is generally positioned by the front and rear ends of the flip seat respectively abutting against the end surface of the lifting seat for positioning. This structure is prone to damage to the contact surface due to excessive force during use; therefore, it is necessary to improve it. Summary of the invention
[0003] The purpose of the utility model is to provide a turning mechanism on a motorcycle backrest in view of the above-mentioned deficiencies in the prior art, which has the characteristic of not being easily damaged during use.
[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a flip mechanism on a motorcycle backrest, including a flip seat, which is hinged to a lifting seat on the motorcycle through a pin shaft, an arc groove is opened on one side of the flip seat, and limit pins are arranged in the arc groove to position the flip seat at both ends of the arc groove when flipping; a positioning mechanism is arranged on the other side of the flip seat, and the positioning mechanism is used to lock the use state of the flip seat.
[0005] The positioning mechanism includes a positioning steel ball, a positioning spring and a positioning plate. The positioning plate is arranged on the flip seat and has a steel ball hole thereon. A portion of the positioning steel ball that is less than 1 / 2 is embedded in the steel ball hole. One end of the positioning spring abuts against the positioning steel ball, and the other end abuts against the lifting seat. There are more than two steel ball holes.
[0006] The flipping angle of the flip seat is 90°.
[0007] After adopting the above structure, the utility model has the following advantages compared with the prior art: the utility model limits and positions the flipping of the flip seat by the cooperation of the limit pin and the arc groove, thus avoiding direct contact and abutment between the flip seat and the motorcycle lifting seat, reducing the collision between the two, and making it less likely to be damaged during use.

[0011] The following description is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention. The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0012] For example, see Figures 1 to 3 As shown: a flip mechanism on a motorcycle backrest, including a flip seat 10, the flip seat 10 is hinged with a lifting seat 20 on the motorcycle through a pin shaft 11. In use, the flip seat 10 not only rotates with the pin shaft 11 as the axis, but also rises and falls in conjunction with the lifting seat 20. An arc groove 12 is provided on one side of the flip seat 10, and the flip angle of the flip seat 10 is 90°. Specifically, under normal circumstances, the angle between the center of the two ends of the arc groove 12 and the axis of the flip seat 10 is 90°. A positioning pin 13 is provided in the arc groove 12, and the other end of the positioning pin 13 is provided in the lifting seat 20, which is used to position the two ends of the arc groove 12 when the flip seat 10 flips; specifically, when the flip seat 10 is in an upright state, the limit pin 13 limits the front end of the arc groove 12, and when the flip seat 10 flips forward, the limit pin 13 can limit the rear end of the arc groove 12. During use, if riding alone, the flip seat 10 can be flipped forward so that the cushion on the flip seat 10 can abut against the rider's lower back for support. At this time, the limit pin 13 is used to limit the rear end of the arc groove 12 to prevent the flip seat 10 from continuing to flip forward. If riding with someone, the flip seat 10 can be placed in an upright state so that the cushion on it can abut against the rider's back for support. At this time, the limit pin 13 is used to limit the front end of the arc groove 12 to prevent the flip seat 10 from continuing to flip backward. A positioning mechanism is provided on the other side of the flip seat 10, and the positioning mechanism is used to lock the use state of the flip seat 10. Specifically, the positioning mechanism can cooperate with the positioning pin 13 to limit the flip seat 10; the positioning mechanism includes a positioning steel ball 16, a positioning spring 14 and a positioning plate 15. The positioning plate 15 is provided on the flip seat 10, and at least two or more steel ball holes are opened thereon. Under normal circumstances, there are four steel ball holes, and less than 1 / 2 of the positioning steel ball 16 is located in the steel ball hole so that it can be removed from the steel ball hole during flipping; one end of the positioning spring 14 abuts on the positioning steel ball 16, and the other end thereof abuts on the lifting seat 20, and the lifting seat 20 has a blind hole for inserting the positioning spring 14 therein; of course, the other end of the positioning spring 14 can also abut against the brim of the pin shaft 11, that is, a through hole can be opened on the lifting seat 20, and the positioning spring 14 passes through the through hole and abuts against the bottom surface of the brim of the pin shaft 11. During flipping, the limiting pin 13 will passively move from one side of the arc groove 12 to the other side for limiting, and the positioning steel ball 16 will fall out of the steel ball hole after being subjected to the flipping force, until the next steel ball hole reaches its position and then is inserted into it for limiting.
