[0002] As motorcycles become more common in daily life, people's standards for the comfort and functionality of motorcycle rear seats are also rising. During riding, due to the individual differences of rear seat passengers, their requirements for backrest angles are diverse, and they all hope to get better support and enjoy a more comfortable experience. In addition, when the backrest is not in use, people also expect it to be easily folded and stored, which can save space and maintain the overall beauty of the motorcycle.

[0003] However, the existing technology of motorcycle rear seat backrests has many shortcomings. First, different passengers have completely different requirements for backrest angles, but some existing backrests can only provide fixed angles. This obviously cannot meet the personalized needs of the majority of passengers, making it difficult for passengers to obtain ideal support during the ride, greatly reducing the comfort of the ride. If you ride in this uncomfortable condition for a long time, it is easy to get tired and uncomfortable. Second, although some backrests can be adjusted in angle, multiple components of the backrest are connected by bolt assemblies. When adjusting the angle, you have to use tools such as wrenches to operate. This method is not only cumbersome and troublesome, but also extremely inconvenient. For users, it will cause many troubles in actual use. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figures 1-5 A motorcycle rear seat backrest that is convenient to fold and store includes a mounting frame 1 and a folding plate 4. The mounting frame 1 is connected to a motorcycle frame through a fixing mechanism. The fixing mechanism includes a connecting block 2 installed on the mounting frame 1. The connecting block 2 is provided with a fixing bolt. With the help of the connecting block 2 and the fixing bolt, the mounting frame 1 and the frame at the rear seat position of the motorcycle can be conveniently disassembled and assembled.

[0027] The mounting frame 1 is provided with two movable grooves 5, a toggle channel 9, a mounting channel 12 and a rotating cavity 16. The two movable grooves 5 and the rotating cavity 16 are rotated together with a double-headed screw 17, and a connecting mechanism corresponding to the mounting frame 1 is installed on the double-headed screw 17. The connecting mechanism includes a positioning rod 6 threadedly connected to the double-headed screw 17. The mounting frame 1 is provided with a positioning channel 3 corresponding to the positioning rod 6. The positioning rod 6 is in the positioning channel 3, thereby realizing the connection between the mounting frame 1 and the folding plate 4, and the disassembly can be realized by separation.

[0028] The vertical cross-section of the movable groove 5, the positioning rod 6 and the positioning channel 3 are all regular hexagons, and the inner walls of the movable groove 5 and the positioning channel 3 and the outer walls of the positioning rod 6 are polished. The regular hexagonal structure is convenient for adjusting the inclination angle of the folding plate 4, and can be overlapped with the mounting frame 1 to complete the folding storage operation.

[0029] A vertical rod 10 is provided in the toggle channel 9, and a rack frame 11 in the rotating chamber 16 is slidably penetrated on the vertical rod 10 through an elastic mechanism, and the elastic mechanism includes a first spring sleeved on the outside of the vertical rod 10, and the two ends of the first spring are respectively connected to the outer wall of the rack frame 11 and the inner wall of the toggle channel 9. The elastic potential energy provided by the first spring realizes the downward pulling operation of the rack frame 11, ensuring that the rack frame 11 can maintain a stable position without external force intervention.

[0030] The rack frame 11 is connected to the double-headed screw 17 through a rotating mechanism, and the rotating mechanism includes a gear 18 arranged on the double-headed screw 17, and the gear 18 is meshed with the rack frame 11. When the rack frame 11 moves, it will cooperate with the gear 18 to drive the double-headed screw 17 to rotate.

[0031] The installation channel 12 is provided with a disassembly frame 7, on which a plurality of waist pads 8 are arranged, and an upper top groove 14 is arranged on the disassembly frame 7. A fixing block 15 is arranged in the upper top groove 14 through a top mechanism, and a fixing channel 13 is arranged on the folding plate 4. The top mechanism includes a second spring arranged in the upper top groove 14, and the two ends of the second spring are respectively connected to the outer wall of the fixing block 15 and the inner bottom wall of the upper top groove 14. The elastic potential energy provided by the second spring realizes the top operation of the fixing block 15, and the fixing block 15 can be pushed into the fixing channel 13.

[0032] The mounting frame 1 is U-shaped in top view, and the U-shaped design facilitates the folding plate 4 to be folded into the U-shaped opening of the mounting frame 1. The disassembly frame 7 is L-shaped in vertical section, and the L-shaped design facilitates its connection with the folding plate 4.

[0033] The disassembly frame 7 and the waist support pad 8 are connected by Velcro, which is convenient for disassembly and assembly, so as to facilitate storage and replacement. An inclined section is provided on the upper end surface of the fixing block 15. The inclined section can automatically press down the fixing block 15 into the upper groove 14 when the horizontal part of the disassembly frame 7 enters the installation channel 12, and when the horizontal part of the disassembly frame 7 enters the installation channel 12, it rises and resets again to enter the fixing channel 13.

[0034] When the utility model is used, the mounting frame 1 is mounted on the frame at the rear seat position of the motorcycle through the fixing bolts on the connecting block 2, the folding plate 4 is adjusted to a suitable angle to provide back support, and the waist pad 8 realizes the protection of the waist and back.

[0035] When it is necessary to adjust the inclination angle of the folding plate 4 or perform folding and storage, pull the rack frame 11 to move it on the vertical rod 10. At this time, the rack frame 11 meshes with the gear 18, thereby driving the double-headed screw 17 to rotate. The rotation of the double-headed screw 17 causes the positioning rod 6 threadedly connected thereto to move within the movable slot 5. Immediately afterwards, the positioning rod 6 disengages from the positioning channel 3. After the disengagement, its inclination angle is adjusted. The single adjustment angle is 30 degrees. After the adjustment is completed, releasing the rack frame 11 allows the positioning rod 6 to re-enter the positioning channel 3. The adjustment of the inclination angle of the folding plate 4 is completed.

[0036] As Figure 1 shown, the folding plate 4 is in a vertical state. When it is adjusted to a horizontal state and enters the U-shaped opening of the mounting frame 1, the folding and storage operation of the folding plate 4 can be completed. Before the folding and storage of the folding plate 4, the disassembly and assembly frame 7 and the lumbar support pad 8 can be disassembled and stored. Specifically: press the fixing block 15 in the fixing channel 13, and the fixing block 15 compresses the second spring and enters the upper top groove 14 and disengages from the fixing channel 13.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
