[0002] At present, motorcycles are a common means of transportation. In order to facilitate the support of riders or passengers, a backrest is generally placed at the rear of the motorcycle. In order to adjust the height, the existing backrest is generally an adjustable structure. Its adjustment structure includes an adjustment rod, an adjustment pressure block, a return spring and a locking rod. A plurality of slots are provided on the adjustment rod. The adjustment pressure block is located on the side of the adjustment rod and connected to the locking rod. By pressing the adjustment pressure block, the locking part on the locking rod is laterally disengaged from the slot on the adjustment rod, so that the adjustment rod can be raised and lowered. After adjusting to a suitable position, the adjustment pressure block is released, and the return spring pushes the locking rod back to its position, so that the locking part of the locking rod is engaged with the slot, and the locking effect can be achieved. Since the locking part of this structure enters the locking from the side of the slot, it achieves a locking effect in the upper and lower positions after matching. However, due to the opening structure of the slot, it is not subject to force restriction in the front and rear directions, so it is easy to shake back and forth during use, and its stability is not good, so it is necessary to improve it.

[0016] 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.
[0017] Example 1, see Figures 1 to 5As shown: a motorcycle backrest, including a backrest 10, a rear seat 20 and a cushion 30, the rear seat 20 is connected to the rear of the backrest 10, and the backrest 10 can be fixed on the rear tail seat of the motorcycle during use. The cushion 30 is connected to the backrest 10 in a liftable manner, and is connected by a lifting and locking mechanism to be adjusted up and down during operation. The lifting and locking mechanism includes two parallel lifting rods 11, a lock seat 12, a push switch 13 and a return spring 14. A sliding sleeve 40 is fixed in the back plate 10. There are two lifting rods 11, which pass through the sliding sleeve 40 and are movably arranged on the back plate 10 up and down. A plurality of locking grooves 15 are provided on the lifting rods 11; the lock seat 12 is located between the two lifting rods 11, and locking blocks 16 are extended to the left and right sides thereof and are movably engaged with the locking grooves 15 on the corresponding lifting rods 11; a through hole is provided on the side of the back plate 10 and passes through the interior thereof. The push switch 13 is arranged in the through hole and is fixedly connected to the lock seat 12; one end of the return spring 14 abuts against the back plate 10, and the other end abuts against the lock seat 12. During use, when the height needs to be adjusted, the push switch 13 is pressed to compress the return spring 14. At the same time, the push switch 13 can drive the lock seat 12 to move forward, so that the locking block 16 escapes from the locking groove 15, so that the lifting rod 11 can be raised and lowered; when locking, the push switch 13 is released, and under the action of the return spring 14, the locking block 16 can be embedded and connected from the front side of the locking groove 15; in this way, while limiting the up and down positions, the front and back positions of the lifting rod 11 can also be limited to avoid the occurrence of shaking.
[0018] In order to make the lock slot 15 and the lock block 16 cooperate smoothly, the lock slot 15 is a concave structure with a wide outside and a narrow inside, and the lock block 16 is a convex structure with a narrow outside and a wide inside. The lock slot 15 and the lock block 16 cooperate with each other in a concave-convex manner, so that when locking, the lock block 16 can be inserted into the lock slot 15 more freely and smoothly. In order to facilitate the lock seat 12 to be placed in the backing plate 10, an opening for the lock seat 12 to enter is opened on the side of the backing plate 10, and the opening is sealed by a cover plate 17, and the cover plate 17 is fixed to the backing plate 10 by bolts 50.
[0019] The back cushion 30 is provided with a flip positioning mechanism, which includes a lifting seat 31, a positioning pin 32, a positioning spring 33, a positioning steel ball 34 and a positioning piece 35. The lifting seat 31 is fixedly connected to the lifting rod 11 to be lifted and lowered in linkage therewith; the back cushion 30 is provided with a flip seat 36, which is hingedly connected to the lifting seat 31; the flip seat 36 is provided with an arc groove 37, and the angle between the center of the two ends of the arc groove 37 and the axis of the flip seat 36 is 90°. The positioning pin 32 is provided on the lifting seat 31, and the end of the positioning pin 32 extends into the arc groove 37 to limit the two ends of the arc groove 37; the positioning piece 35 is provided on the flip seat 36, and four steel ball holes are opened thereon, and less than 1 / 2 of the steel ball 34 is located in the steel ball hole so that it can be removed from the steel ball hole when flipping; one end of the positioning spring 33 abuts on the steel ball 34, and the other end thereof abuts on the lifting seat 31. During flipping, the positioning pin 32 will passively move from one side of the arc groove 37 to the other side for positioning, and the steel ball 34 will fall out of the steel ball hole after receiving the flipping force, until the next steel ball hole reaches its position and then snaps into it for positioning.
[0020] Example 2, see Figure 6 The structure of Example 2 is roughly the same as that of Example 1, except that a chamber is provided at the top of the back plate 10 for the lock seat 12 to enter, a fixed seat 18 is provided in the chamber, the lock seat 12 is provided on the fixed seat 18, and a space is provided on the fixed seat 18 for the lock seat 12 to move back and forth; it can also achieve the effect of Example 1.
