Detailed implementation manners

[0026] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in combination with specific embodiments.

[0027] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, a sliding adjustable seat structure includes a seat 1, a connecting cover plate 2 is fixedly installed at the bottom of the seat 1, the connecting cover plate 2 is composed of a mirror-symmetrical combination, and a slide rail seat 3 for connecting the bicycle body is arranged outside the connecting cover plate 2, and the slide rail seat 3 is inclined;

[0028] A plate cavity 4 is opened inside adjacent two groups of connecting cover plates 2, and moving blocks 5 are fixedly installed on both sides of the connecting cover plate 2. A rotating shaft 6 is rotatably installed inside the plate cavity 4, and a cam 7 is fixedly installed outside the rotating shaft 6. A torsion spring 8 is sleeved on the rotating shaft 6 on one side of the cam 7. Limit pins 9 are fixedly installed on both sides of the end of the cam 7 away from the rotating shaft 6, and an arc groove 10 for the limit pins 9 to penetrate through is opened inside the connecting cover plate 2;

[0029] Inside the slide rail base 3, a first - level slide groove 11 for accommodating the movement of the moving block 5 is provided. On one side of the first - level slide groove 11 and within the slide rail base 3, a second - level slide groove 13 is provided. Inside the second - level slide groove 13, a wave track 12 is fixedly installed. The second - level slide groove 13 is used to accommodate the movement of the limit pin 9. The wave track 12 divides the second - level slide groove 13 into a return slide groove 14 and an adjustment slide groove 17, and the return slide groove 14 and the adjustment slide groove 17 are connected.

[0030] In this embodiment, it is connected to the bicycle body in an overall inclined state. When it is necessary to adjust the horizontal distance and height of the seat 1, inside the wave track 12, when its first - level step enters the second - level step, pulling the connection cover plate 2 of the seat 1 to move rightward first, the limit pin 9 moves rightward simultaneously and will move upward along the upper - half arc surface of the wave track 12, while the torsion spring 8 will pull the limit pin 9 back to the initial position through the connected cam 7. Therefore, after the limit pin 9 crosses the first - level step, it will fall into the second - level step. Overall, it takes into account the differences in the height and arm span of users, adjusts the seat, and finds the most reasonable seat height and horizontal distance.

[0031] As an embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, the wave track 12 is in a stepped shape, and the inclination angle of the wave track 12 is the same as the inclination angle of the slide rail base 3. At least two sets of wave structures are provided on the wave track 12.

[0032] In this embodiment, when the seat 1 slides in the slide rail base 3, the limit pin 9 swings up and down following the shape of the adjustment slide groove 17 on one side of the wave track 12, driving the cam 7 to perform a circular motion inside the connection cover plate 2. When the cam 7 performs a circular motion up and down, the torsion spring 8 will rely on its own elasticity to pull it back to the initial position, in the middle of the arc groove 10;

[0033] The two sets of wave structures can enable different adjustment degrees of the seat 1.

[0034] As an embodiment, as Figure 3 、 Figure 4 shown, one end of the slide rail base 3 is open - ended, and the opening is connected to the return slide groove 14.

[0035] In this embodiment, the whole is connected to the bicycle body. The connection cover plate 2 at the bottom of the seat 1 is inserted into the opening inside the slide rail base 3, and the square - structured moving block 5 moves along the inside of the first - level slide groove 11, which is convenient for installation during assembly.

[0036] As an embodiment, as Figure 5 shown, a protrusion 16 is provided at the bottom end of the connection cover plate 2, and the bottom end of the first - level slide groove 11 corresponds to the protrusion 16.

[0037] In this embodiment, when the limit pin 9 moves along the return chute 14 until the end, it is snapped into the limit hole 15. At this time, the protrusion 16 of the connection cover plate 2 gradually moves along the primary chute 11 in the slide rail base 3, ensuring smooth movement.

[0038] As an embodiment, as Figure 4 shown, a limit hole 15 is provided at one end of the secondary chute 13, and the limit hole 15 is used to limit the limit pin 9.

[0039] In this embodiment, as the moving block 5 moves to the left, the limit pin 9 repeats the movement trajectory of sliding up and down in the adjustment chute 17 of the secondary chute 13. When the limit pin 9 moves along the return chute 14 to the lowest position and is snapped into the limit hole 15, the height of the seat 1 is the lowest and is located at one end. When the seat 1 is moved again, without the groove below blocking the limit pin 9, when the seat 1 is moved again, the limit pin 9 slides into the upper adjustment chute 17 and falls into the interior of the wave track 12, thus gradually rising.

[0040] As an embodiment, as Figure 1 、 Figure 2 、 Figure 3 shown, the primary chute 11 and the secondary chute 13 are both arranged symmetrically with respect to the center of the slide rail base 3, and the thickness of the primary chute 11 corresponds to the thickness of the moving block 5.

[0041] In this embodiment, through the mirror-image primary chute 11 and secondary chute 13 in the slide rail base 3, the two sides of the connection cover plate 2 at the bottom of the seat 1 move within the slide rail base 3, improving the overall support strength and preventing structural deformation.

[0042] As an embodiment, as Figure 2 、 Figure 3 、 Figure 4 shown, the moving block 5 matches the primary chute 11, and the secondary chute 13 matches the limit pin 9.

[0043] Among them, the moving block 5 has a square structure, and the limit pin 9 has a cylindrical structure.

[0044] In this embodiment, by the square-structured moving block 5 moving along the interior of the primary chute 11 and the cylindrical-structured limit pin 9 moving within the secondary chute 13, and using the wave track 12 being arranged in a stepped manner, the limit pin 9 repeats the movement trajectory of sliding up and down in the adjustment chute 17, realizing the adjustment of the height and horizontal distance of the seat 1.

[0045] Working principle: When in use, the whole body is connected to the bicycle body in an inclined state, the connecting cover plate 2 at the bottom of the seat 1 is inserted into the opening of the slide rail seat 3, and the moving block 5 with a square structure moves along the first-level slide groove 11. During the movement of the moving block 5, the limit pin 9 in the connecting cover plate 2 enters from the return slide groove 14 and moves to the bottom. After the limit pin 9 moves along the return slide groove 14 and is inserted into the limit hole 15 at the lowest point, the height of the seat 1 is the lowest and is located at one end;

[0046] Move the seat 1 again. There is no groove blocking the limit pin 9 and the bottom. After moving a certain distance, the seat 1 enters the secondary slide groove 13 along the arc surface of the wave track 12. The limit pin 9 slides into the upper adjustment slide groove 17 and falls into the inside of the wave track 12. Under the action of the torsion spring 8, the seat 1 moves upward to the inside of the adjustment slide groove 17 and enters the first step of the wave track 12, supporting the groove in the groove. If the driver sits on the seat 1 at this time, the wave track 12 and the limit pin 9 will combine to provide upward support for the seat 1 to stabilize the seat 1.

[0047] When it is necessary to adjust the horizontal distance and height of the seat 1, the first step is entered into the second step inside the wave track 12, and the connecting cover plate 2 of the seat 1 is pulled to the right first, and the limit pin 9 moves to the right at the same time, and will move upward along the upper half of the arc surface of the wave track 12, and the torsion spring 8 will pull the limit pin 9 back to the initial position through the connected cam 7. Therefore, the limit pin 9 will fall into the second step after crossing the first step and be stuck in the groove in the adjusting slide groove 17 in the wave track 12. Similarly, as the moving block 5 moves to the right, the limit pin 9 repeats the movement trajectory of sliding up and down in the adjusting slide groove 17 in the secondary slide groove 13. When the limit pin 9 is stuck in the last step, the seat 1 is at the highest point at one end of the slide rail seat 3. The seat 1 is moved again, and the limit pin falls into the return slide groove 14 again after the adjusting slide groove 17. The overall consideration is given to the differences in height and arm span of the users, and the seat 1 is adjusted in two dimensions to find the most reasonable height and horizontal distance of the seat 1.
