Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, specifically to a folding sliding seat for a tricycle and a tricycle. Background Technology

[0002] As a special mode of transportation, tricycles play an indispensable role in people's lives and production. The seat, a key component of a tricycle, directly affects the comfort and safety of the rider and passengers, and occupies an important position in the overall vehicle design. The most basic function of a tricycle seat is to provide comfortable support for the rider and passengers. Most tricycle seats have fixed backrests, which cannot be adjusted to suit the needs of the rider and passengers. Different riders have different sitting postures, and changes in road conditions during travel also require different backrest angles. For example, when climbing hills, riders may prefer a steeper backrest angle for better lumbar support; when riding on flat roads, they prefer a gentler backrest angle to relax their backs. However, existing fixed backrests cannot meet these personalized needs, reducing riding comfort.

[0003] Meanwhile, application number 201922258355.1, entitled "A Three-Wheeled / Electric Three-Wheeled Vehicle Body Structure", is able to flip the seat of a single-wheeled vehicle and provide backrests for the driver and rear passengers, but it cannot switch the position of the front and rear backrests to increase the space of the seat. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned technical solutions, the purpose of this utility model is to provide a folding sliding seat for tricycles.

[0005] This utility model provides a tricycle.

[0006] The objective of this utility model is achieved through the following technical solution.

[0007] A folding sliding seat for a tricycle includes a backrest, a support rod, a sliding assembly, side guardrail tubes, and a limiting assembly. A sliding assembly is hinged to each of the left and right ends of one side of the support rod. The backrest is installed on the other side of the support rod. Each sliding assembly is slidably installed on one side guardrail tube. A limiting assembly is provided at each of the front and rear ends of each side guardrail tube. A limiting tooth matching the limiting assembly is provided at the bottom of the sliding assembly.

[0008] In the above technical solution, a cushion is installed below the two side guardrail tubes.

[0009] In the above technical solution, the length of the seat cushion is equal to or greater than the length of the side guardrail tube.

[0010] In the above technical solution, each of the limiting components includes a mounting post, a limiting hook, a torsion spring, and a limiting block. The mounting post is fixedly installed at the bottom of one end of the side guardrail tube. The limiting hook is hinged to the mounting post. The torsion spring is disposed at the hinge. The limiting block is fixedly installed on the mounting post. The bottom of the limiting block is in close contact with the limiting hook.

[0011] In the above technical solution, the limiting hook includes a horizontal rod and a hook tooth disposed at the end of the horizontal rod, forming a right-angle limiting groove between the hook tooth and the end of the horizontal rod.

[0012] In the above technical solution, a pull ring is installed at the bottom of the horizontal bar.

[0013] In the above technical solution, each of the sliding components includes a sliding sleeve, the backrest is rotatably mounted on the sliding sleeve, and two limiting teeth are fixedly installed at the bottom of the sliding sleeve. One limiting tooth matches the limiting component on the rear side of the side guardrail tube, and the other limiting tooth matches the limiting component on the front side of the side guardrail tube.

[0014] Another aspect of this utility model includes a tricycle, which includes the aforementioned folding sliding seat.

[0015] The advantages and beneficial effects of this utility model are as follows:

[0016] 1. This utility model enables the tricycle to switch the position of the front and rear backrests by setting sliding components and limiting components on the side guardrail tubes, thereby increasing the seat space and facilitating rest for the driver or rear passengers.

[0017] 2. The limiting component and limiting tooth of this utility model have a simple structure. By pushing the backrest to move on the side guardrail tube, the limiting tooth is locked in the right-angle limiting groove of the limiting component, thus limiting the backrest. When it is necessary to move the backrest, simply pull down the limiting hook through the pull ring to release the limiting and push the backrest to move. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to specific embodiments.

[0024] Example 1

[0025] like Figures 1-4 As shown, a folding sliding seat for a tricycle includes a backrest 1, a support rod 8, a sliding assembly 2, a side guardrail tube 3, and a limiting assembly 4. A sliding assembly 2 is hinged to each of the left and right ends of one side of the support rod 8. The backrest is mounted on the other side of the support rod 8. The support rod 8 rotates forward along its hinge point with the sliding assembly, serving as the backrest for the driver. The support rod 8 also rotates backward along its hinge point with the sliding assembly, serving as the backrest for the rear passenger. Each sliding assembly 2 is slidably mounted on a side guardrail tube 3. A limiting assembly 4 is provided at each of the front and rear ends of each side guardrail tube 3. A limiting tooth 16 matching the limiting assembly 4 is provided at the bottom of the sliding assembly 2 to limit the sliding of the backrest 1 to the front or rear end of the side guardrail tube 3, thereby increasing the seat space. Furthermore, the support rod does not need to be too long to allow for switching between the front and rear backrest positions, enabling the driver or rear passenger to rest adequately.

[0026] like Figure 1 As shown, a seat cushion 5 is further provided below the two side guardrail tubes 3. When the backrest 1 slides to the rear of the side guardrail tube 3, the space of the driver's seat increases, making it easier for the driver to rest. When the backrest 1 slides to the front of the side guardrail tube 3, it provides a place for the rear seat passengers to rest.

[0027] Furthermore, the length of the seat cushion 5 is equal to or greater than the length of the side guardrail tube 3.

[0028] like Figure 2 As shown, each of the limiting components 4 further includes a mounting post 6, a limiting hook 7, a torsion spring, and a limiting block 9. The mounting post 6 is fixedly installed at the bottom of one end of the side guardrail tube 3. The limiting hook 7 is hinged to the mounting post 6. The torsion spring is located at the hinge to provide an upward elastic force to the limiting hook 7, keeping the limiting hook 7 horizontal. The limiting block 9 is fixedly installed on the mounting post 6. The bottom of the limiting block 9 is in close contact with the limiting hook 7 to keep the limiting hook 7 horizontal and ensure that the limiting tooth 16 can be engaged to limit the backrest 1.

[0029] like Figure 2 As shown, the limiting hook 7 further includes a horizontal rod 11 and a hook tooth 12 disposed at the end of the horizontal rod 11. A right-angle limiting groove is formed between the hook tooth 12 and the end of the horizontal rod 11. An inclined arc surface 13 is provided on the hook tooth 12, and an inclined surface 14 is provided on the limiting tooth 16. The limiting tooth 16 presses the inclined arc surface 13 downward through the inclined surface 14 until the limiting tooth 16 enters the right-angle limiting groove, and finally limits the backrest 1 to one end of the side guardrail tube 3.

[0030] Furthermore, a pull ring 10 is installed at the bottom of the horizontal bar 11. When it is necessary to release the current limit, pull the pull ring 10 downwards and pull the backrest 1 towards the other end of the side guardrail tube 3 by hand. The limit tooth 16 disengages from the right-angle limit groove, thereby realizing the sliding of the backrest 1.

[0031] like Figure 3 As shown, each of the sliding components 2 further includes a sliding sleeve 15, and the backrest 1 is rotatably mounted on the sliding sleeve 15. Two limiting teeth 16 are fixedly installed at the bottom of the sliding sleeve 15. One limiting tooth 16 matches the limiting component 4 at the rear end of the side guardrail tube 3. When the sliding component 2 is slid backward, the limiting tooth 16 is limited between the mounting post 6 and the hook tooth 12 on the rear side, located in the right-angle limiting groove. The other limiting tooth 16 matches the limiting component 4 at the front end of the side guardrail tube 3. When the sliding component 2 is slid forward, the limiting tooth 16 is limited between the mounting post 6 and the hook tooth 12 on the front side, located in the right-angle limiting groove.

[0032] Furthermore, a support is provided at the top of the sliding sleeve 15, and the support rod 8 is hinged to the support and located outside the support, so that the bend of the support rod 8 can overlap the side guardrail tube 3 to provide support for the backrest 1.

[0033] like Figure 4 As shown, two support blocks 17 can also be set at the top of the side guardrail tube 3. When the backrest 1 is folded backward or forward, the support blocks 17 support the backrest to keep it upright, thus providing better support.
