Description

Technical Field

[0001] This utility model belongs to the technical field of two-wheeled vehicle accessories, and relates to an adjustable backrest for the rear rack of a two-wheeled vehicle. Background Technology

[0002] The rear rack of a two-wheeled vehicle is an important accessory. Its main function is to provide a platform for placing and securing items. When a passenger is on the back seat, the rear rack can also act as a handrail, making the passenger more stable. To improve the comfort and safety of rear passengers, existing technology includes a structure that installs a backrest on the rear rack. The backrest supports the back of the rear passenger, making the ride more comfortable and preventing the passenger from falling off from behind.

[0003] However, existing rear rack backrests still have some shortcomings. The backrests are usually fixedly connected to the rear rack, and their height cannot be adjusted, failing to meet the needs of rear passengers. When two-wheeled vehicles need to carry large loads, the backrests can obstruct the load and make them difficult to secure. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing an adjustable backrest for the rear rack of a two-wheeled vehicle. The technical problem to be solved by this utility model is: how to make the backrest on the rear rack adjustable.

[0005] The purpose of this utility model can be achieved through the following technical solution: an adjustable backrest for a two-wheeled vehicle rear rack, including a frame, armrests on both sides of the frame, an mounting plate on the inner side of the armrests, a first mounting hole on the mounting plate, an integrally connected connecting frame at the bottom of the frame, a slot on the connecting frame, a backrest plate for snap-fit ​​connection inside the slot, a first limiting hole and a second limiting hole at the upper and lower ends of the slot, and the bottom end of the backrest plate can be snap-fit ​​connected to the first limiting hole or the second limiting hole respectively.

[0006] In this design, the mounting plate connects to the rear of the two-wheeled vehicle. Bolts pass through the first mounting hole, securing the entire rear rack to the vehicle. The armrests on both sides provide grip for rear passengers. By creating slots in the connecting frame, the backrest panel can move up and down along the slots, thus adjusting its height. In this way, the bottom of the backrest panel can engage with either the first or second limiting hole, thereby changing the backrest height to meet the different height requirements of rear passengers.

[0007] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, the bottom of the backrest panel has a countersunk hole, and the bottom of the countersunk hole has a connecting hole. An adjusting block is installed inside the countersunk hole, with one end of the adjusting block inside the connecting hole and the other end protruding from either a first or second limiting hole. When the connecting hole is aligned with the first limiting hole, inserting the adjusting block into both the connecting hole and the first limiting hole allows the backrest panel to be adjusted to a higher position. When the connecting hole is aligned with the second limiting hole, inserting the adjusting block into both the connecting hole and the second limiting hole allows the backrest panel to be adjusted to a lower position.

[0008] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, the top of the adjusting block is equipped with a knob, which is located inside a countersunk hole. The outer wall of the knob fits against the inner wall of the countersunk hole. The bottom outer wall of the adjusting block has an outwardly protruding limiting part. The top of the first limiting hole and the second limiting hole have clearance grooves, through which the limiting part can pass. The knob is used to adjust the orientation of the adjusting block. When the limiting part on the adjusting block is rotated to the top, the limiting part aligns with the clearance groove, allowing the adjusting block to be inserted into the first or second limiting hole. This facilitates the snap-fit ​​connection between the backrest and the connecting frame. Similarly, the adjusting block can be removed, the backrest adjusted to a suitable height, and then the adjusting block reinserted for convenient height adjustment. Because the limiting part is located on one side of the adjusting block, under the influence of gravity, the side with the limiting part will face the bottom during the movement of the two-wheeled vehicle, preventing the adjusting block from falling off.

[0009] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, when the bottom of the knob abuts against the bottom wall of the countersunk hole, the limiting part can protrude from the bottom of the first limiting hole or the second limiting hole. The knob and the limiting part are integrally formed with the adjusting block. After the backrest panel is engaged with the connecting frame, the bottom of the knob abuts against the bottom wall of the countersunk hole, and the upper end of the limiting part abuts against the bottom of the connecting frame, which is used to fix the position of the backrest panel. The integral forming method can improve the structural strength of the adjusting block.

[0010] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, the top of the backrest panel is provided with abutment parts that open to both sides. The abutment parts at the top can provide support for rear passengers and improve comfort.

[0011] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, the frame and the armrests on both sides are arranged horizontally. After removing the adjustment block from the first or second limiting hole, the back panel can be pulled out of the slot, avoiding interference with the back panel and allowing larger goods to be placed on the rear seat of the two-wheeled vehicle. The horizontal arrangement also improves the stability of the goods.

[0012] In the adjustable backrest of the rear rack of the aforementioned two-wheeled vehicle, the bottom of the connecting frame is provided with an integrally connected mounting platform, and the mounting platform has a second mounting hole inside. Both the mounting platform and the mounting plate are used to connect to the two-wheeled vehicle.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this solution, the bottom of the backrest can be connected to the first limiting hole or the second limiting hole respectively, thereby changing the height of the backrest to meet the needs of rear passengers for different backrest heights.

[0015] 2. In this design, the knob is used to adjust the orientation of the adjusting block. When the limiting part on the adjusting block is rotated to the top, the limiting part aligns with the clearance groove, allowing the adjusting block to be inserted into the first or second limiting hole. This facilitates the snap-fit ​​connection between the backrest and the connecting frame. Similarly, the adjusting block can be removed, the backrest adjusted to a suitable height, and then the adjusting block inserted again for convenient height adjustment. Because the limiting part is located on one side of the adjusting block, under the influence of gravity, the side with the limiting part will face the bottom during the two-wheeled vehicle's movement, preventing the adjusting block from falling off.

[0016] 3. In this solution, after the adjusting block is removed from the first or second limiting hole, the back panel can be pulled out of the slot, avoiding interference with the back panel and allowing larger cargo to be placed on the back seat of the two-wheeled vehicle.

[0024] like Figure 2 Combination Figure 3 As shown, the upper and lower ends of the slot 5a are respectively provided with a first limiting hole 5b and a second limiting hole 5c. The bottom of the countersunk hole 4a is provided with a connecting hole 4c. The countersunk hole 4a is provided with a locking adjustment block 7. One end of the adjustment block 7 is located inside the connecting hole 4c, and the other end protrudes from the first limiting hole 5b or the second limiting hole 5c. The top of the adjustment block 7 is provided with a knob 7a. The knob 7a is located inside the countersunk hole 4a. The bottom of the knob 7a abuts against the bottom wall of the countersunk hole 4a. The outer side wall of the knob 7a fits against the inner side wall of the countersunk hole 4a. The bottom outer side wall of the adjustment block 7 is provided with an outwardly protruding limiting part 7b. The top of the first limiting hole 5b and the second limiting hole 5c is provided with a relief groove 5d. The limiting part 7b can pass through the relief groove 5d. The upper end of the limiting part 7b abuts against the bottom of the connecting frame 5. The frame 1 and the handrails 2 on both sides are arranged in a horizontal state.

[0025] The working principle of this solution is as follows: Figure 1-3As shown, mounting plate 3 and mounting platform 6 are used to connect to the rear of the two-wheeled vehicle. Bolts pass through the first mounting hole 3a and the second mounting hole 6a to secure the entire rear rack to the two-wheeled vehicle. Knob 7a is used to adjust the orientation of the adjusting block 7. When the limiting part 7b on the adjusting block 7 is rotated to the top, the limiting part 7b aligns with the clearance groove 5d, allowing the adjusting block 7 to be inserted into either the first limiting hole 5b or the second limiting hole 5c. This facilitates the snap-fit ​​connection between the backrest panel 4 and the connecting frame 5. Similarly, the adjusting block 7 can be removed, the backrest panel 4 adjusted to a suitable height, and then the adjusting block 7 inserted again, allowing for convenient height adjustment of the backrest panel 4 to meet the different height requirements of rear passengers. Because the limiting part 7b is located on one side of the adjusting block 7, under the influence of gravity, the side with the limiting part 7b will face downwards during the movement of the two-wheeled vehicle, preventing the adjusting block 7 from falling off. When large items need to be transported, after the adjusting block 7 is removed from the first limiting hole 5b or the second limiting hole 5c, the back panel can be pulled out from the slot 5a to avoid interference with the back panel 4, so that the rear seat of the two-wheeled vehicle can accommodate larger goods.
