Riders need the backrest to provide support and protection during starting or driving to improve riding stability and safety. Therefore, while considering the flexible adjustment of the backrest, the supporting function of the backrest should also be considered. Secondly, most of the existing motorcycle rear racks with adjustable backrests have the problem of unstable cargo fixation. Most general racks only use a belt to bind the cargo, and the racks are small. When the cargo is large, the racks cannot play a good fixing effect and there is a risk of the cargo falling.

[0030] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1-4The utility model provides an embodiment: a motorcycle rear rack with an adjustable backrest, comprising a large support arm 1, the inner wall of the large support arm 1 is fixedly connected with a rotating shaft 2, the outer wall of the rotating shaft 2 is fixedly connected with a limiting structure, the outer wall of the limiting structure is fixedly connected with a small support arm 4, the outer wall of the small support arm 4 is rotatably connected to the outer wall of the rotating shaft 2, the end of the small support arm 4 is fixedly connected with a supporter 5, the outer wall of the supporter 5 is fixedly connected with a cushion 6, the inner wall of the large support arm 1 is rotatably connected with a support rod 7, the outer wall of the support rod 7 is fixedly connected with the limiting structure, the outer wall of the limiting structure is fixedly connected to the outer wall of the large support arm 1, the outer wall of the support rod 7 is fixedly connected with a plurality of connecting rods 8, the support Two connecting rods 8 are fixedly connected to the outer wall of the support rod 7, and the limiting structure is that the outer wall of the rotating shaft 2 is fixedly connected to the fixture 3, the outer wall of the small supporting arm 4 is fixedly connected to the ratchet 17, the inner wall of the ratchet 17 is rotatably connected to the outer wall of the rotating shaft 2, the outer wall of the fixture 3 is rotatably connected to the position of the ratchet 17, and the outer wall of the fixture 3 is provided with a spring sheet 19 at the position of the ratchet 18, the inner wall of the ratchet 18 is fixedly connected to the reset rod 20, the outer wall of the reset rod 20 is penetrated on the inner wall of the fixture 3, the inner wall of the fixture 3 is slidably connected to the slide rod 22, the outer wall of the slide rod 22 is fixedly connected to the spring bar 21, and the end of the spring bar 21 is fixedly connected to the inner wall of the fixture 3.

[0033] Specifically, first, the spring bar 21 is adjusted to disengage from the surface of the ratchet 17 by the sliding rod 22, and then the large support arm 1 is rotated along the outer wall of the support rod 7. The rotation of the large support arm 1 drives the ratchet 17 to rotate. When the large support arm 1 is adjusted to a suitable position, the sliding rod 22 is released, and the ratchet 17 cannot move under the action of the pawl 18 and the spring bar 21, thereby achieving a limiting effect. Then, the small support arm 4 is rotated along the rotating shaft 2 in the same manner. The rotation of the small support arm 4 drives the other ratchet 17 to rotate. When the small support arm 4 is adjusted to a suitable position, the other ratchet 17 cannot move under the action of another pawl 18 and the spring bar 21, thereby achieving a limiting effect. The rotation of the small support arm 4 drives the support device 5 to move, and the movement of the support device 5 drives the cushion 6 to move. This part of the structure mainly introduces the working principle of the limiting structure and the specific adjustment process of the adjustment structure. Compared with the previous adjustment method, this adjustment structure can support the human body in multiple directions, thereby increasing the safety effect.

[0034] The end of the support rod 7 is fixedly connected to a hydraulic rod 19, the end of the support rod 7 is fixedly connected to a hydraulic rod 2 13, the outer wall of the hydraulic rod 19 is fixedly connected to a fixing rod 10, the end of the fixing rod 10 is fixedly connected to the outer wall of the hydraulic rod 2 13, the end of the hydraulic rod 19 is fixedly connected to an adjusting rod 11, the end of the adjusting rod 11 is fixedly connected to the outer wall of the hydraulic rod 2 13, the outer wall of the adjusting rod 11 is fixedly connected to a clamp 12, the outer wall of the hydraulic rod 19 is fixedly connected to a belt box 14, the inner wall of the belt box 14 is installed with a buckle 15, and the outer wall of the hydraulic rod 2 13 is fixedly connected to a limiter 16.

[0035] Specifically, first adjust the hydraulic rod 19 and the hydraulic rod 2 13 to make the adjustment rod 11 to the appropriate position, then place the goods on the top of the hydraulic rod 19 and the hydraulic rod 2 13, and then retract the hydraulic rod 19 and the hydraulic rod 2 13 to make the adjustment rod 11 drive the clamp 12 to move, so that the clamp 12 and the large support arm 1 clamp the goods, and then pull out the buckle 15 from the belt box 14. Because the end of the buckle 15 is connected to the belt inside the belt box 14, the buckle 15 is clamped in the groove of the limiter 16 along the goods, so that the belt fixes the goods. This part of the structure mainly introduces the main working principle of the fixing structure. Different from the previous belt fixing, this fixing structure can be adjusted according to the size of the goods, making the fixation more flexible.

[0036] Working principle: first, adjust the spring strip 21 to be separated from the surface of the ratchet 17 through the slide bar 22, then rotate the large support arm 1 along the outer wall of the support rod 7, and the rotation of the large support arm 1 drives the ratchet 17 to rotate. When the large support arm 1 is adjusted to a suitable position, release the slide bar 22, and the ratchet 17 cannot move under the action of the pawl 18 and the spring strip 21, thereby achieving a limiting effect. Then, rotate the small support arm 4 along the rotating shaft 2, and the rotation of the small support arm 4 drives another ratchet 17 to rotate. When the small support arm 4 is adjusted to a suitable position, the other ratchet 17 cannot move under the action of another pawl 18 and the spring strip 21, thereby achieving a limiting effect. As a result, the small support arm 4 rotates to drive the support device 5 to move, and the support device 5 moves to drive the cushion 6 to move. Then, the hydraulic rod 19 and the hydraulic rod 2 13 are adjusted to make the adjusting rod 11 to a suitable position, and then the goods are placed on the top of the hydraulic rod 19 and the hydraulic rod 2 13, and then the hydraulic rod 19 and the hydraulic rod 2 13 are contracted to make the adjusting rod 11 drive the clamp 12 to move, so that the clamp 12 and the large support arm 1 clamp the goods, and then the buckle 15 is pulled out from the belt box 14. Because the end of the buckle 15 is connected to the belt inside the belt box 14, the buckle 15 is clamped in the groove of the limiter 16 along the goods, so that the belt fixes the goods.
