Technical Field

[0001] This utility model relates to the field of automatic vehicle technology, specifically to a bicycle seat structure that is easy to adjust. Background Technology

[0002] In the field of cycling, the bicycle seat, as a key component that comes into direct contact with the cyclist, is crucial for the riding experience and the cyclist's health due to its comfort and adjustability. Appropriate seat height and angle can effectively reduce fatigue during cycling and lower the risk of physical injuries caused by prolonged riding, such as knee pain and lower back discomfort.

[0003] Currently, most common bicycle seat adjustment structures on the market have limited functions, mainly focusing on adjusting the seat height. They cannot meet the personalized needs of riders for seat angle. In actual riding, different riding postures, road conditions, and the rider's physical condition may all require appropriate adjustments to the seat angle to obtain a more comfortable riding experience and better handling performance. Therefore, we propose an easily adjustable bicycle seat structure to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, the present invention provides a bicycle seat structure that is easy to adjust, thus solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] An easily adjustable bicycle seat structure includes a seat post. A support block is welded between the inner walls of both sides of the seat post. A lead screw is rotatably connected to the support block. A first gear is welded to the bottom end of the lead screw. A T-shaped rod is rotatably connected to one side of the seat post. The end of the T-shaped rod extends into the seat post and is welded to a second gear, which meshes with the first gear. A lifting column is threaded onto the lead screw. The top of the lifting column has a U-shaped groove with openings on both sides. A rotating rod is rotatably connected between the inner walls of the two sides of the U-shaped groove. The end of the rotating rod extends outside the lifting column and is welded to a knob. The knob has two locking pins. The ends of the two locking pins are welded to the same pull block. Two first springs are welded between one side of the pull block and one side of the knob. A connecting rod is welded to the rotating rod. A seat is located at the top of the connecting rod. Multiple slots are annularly formed on one side of the lifting column, and the locking pins engage with one of the multiple slots.

[0009] Furthermore, the first spring is movably sleeved on the corresponding locking pin.

[0010] Furthermore, limit grooves are provided on both the left and right inner walls of the seat tube, and limit blocks are slidably connected to the limit grooves. The limit blocks are welded to one side of the lifting column.

[0011] Furthermore, the T-shaped rod has multiple fixing grooves arranged in a ring, and a square is welded to the front side of the seat tube.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a conveniently adjustable bicycle seat structure, which has the following advantages:

[0016] This invention allows for height adjustment by rotating a T-shaped rod, which in turn drives a second gear to rotate a first gear. The first gear, via a lead screw, moves a lifting column, which in turn moves a connecting rod via a rotating rod. The connecting rod then moves the seat, allowing for height adjustment. Pulling a lever moves a locking pin and stretches a first spring, causing the locking pin to separate from one of the multiple locking slots. Rotating a knob rotates a rotating rod, which in turn rotates the connecting rod, causing the seat to rotate. After adjusting to a suitable angle, releasing the lever releases the tension on the lever, causing the first spring to return to its original position. The first spring then moves the locking pin via the lever, engaging it with another slot in the multiple locking slots. This allows for both height and angle adjustment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-5 As shown in the figure, an embodiment of this utility model proposes a conveniently adjustable bicycle seat structure, including a seat tube 1, a support block 2 welded between the inner walls of both sides of the seat tube 1, a lead screw 3 rotatably connected to the support block 2, a first gear 4 welded to the bottom end of the lead screw 3, a T-shaped rod 5 rotatably connected to one side of the seat tube 1, the end of the T-shaped rod 5 extending into the seat tube 1 and welded with a second gear 6, the second gear 6 meshing with the first gear 4, a lifting column 7 threadedly connected to the lead screw 3, and a U-shaped groove 8 with openings on both sides at the top of the lifting column 7. A rotating rod 9 is rotatably connected between the inner walls of the two sides of the groove 8. The end of the rotating rod 9 extends to the outside of the lifting column 7 and is welded with a knob 10. The knob 10 is provided with two locking pins 11. The ends of the two locking pins 11 are welded with the same pull block 12. Two first springs 13 are welded between one side of the pull block 12 and one side of the knob 10. A connecting rod 15 is welded to the rotating rod 9. The top of the connecting rod 15 is provided with a seat 16. Multiple locking slots 14 are opened in a ring on one side of the lifting column 7. The locking pin 11 is engaged with one of the multiple locking slots 14.

[0026] During use, the height of the seat 16 can be adjusted by rotating the T-shaped rod 5, and the angle of the seat 16 can be adjusted by rotating the knob 10. Thus, both the height and the angle can be adjusted.

[0027] In use, when the height of the seat 16 needs to be adjusted, pull the T-shaped lever 20. During the movement, the T-shaped lever 20 stretches the second spring 21, causing the T-shaped lever 20 to separate from one of the multiple fixing slots 18. Then, rotate the T-shaped rod 5. The T-shaped rod 5 drives the first gear 4 to rotate through the second gear 6. The first gear 4 drives the lead screw 3 to rotate. The lead screw 3 drives the lifting column 7 to move. The lifting column 7 drives the limiting block 17 to slide on the limiting slot 22. The lifting column 7 drives the connecting rod 15 to move through the rotating rod 9. The connecting rod 15 drives the seat 16 to move, thereby adjusting its height. After adjustment, release the force on the T-shaped lever 20. At this time, the second spring 21, which was in a stretched state, returns to its original position. The second spring 21 drives the T-shaped lever 20 to separate from the multiple fixing slots 18. Another fixed slot 18 in the fixed slot 18 is engaged. When the angle of the seat 16 needs to be adjusted, the pull block 12 is pulled. During the movement of the pull block 12, the first spring 13 is stretched. The pull block 12 drives the locking pin 11 to move, so that the locking pin 11 is separated from one of the multiple locking slots 14. Then, the knob 10 is turned. The knob 10 drives the rotating rod 9 to rotate. The rotating rod 9 drives the connecting rod 15 to rotate. The connecting rod 15 drives the seat 16 to rotate. After adjusting the appropriate angle, the pulling force on the pull block 12 is released. At this time, the first spring 13, which was in a stretched state, returns to its original state. The first spring 13 drives the locking pin 11 to move through the pull block 12, so that the locking pin 11 is engaged with another of the multiple locking slots 14. Thus, both the height and the angle can be adjusted.

[0028] In some embodiments, the first spring 13 is movably sleeved on the corresponding locking pin 11.

[0029] The rotating knob 10 is secured by two locking pins 11 to prevent accidental rotation of the knob 10.

[0030] In some embodiments, a limiting groove 22 is provided on both the left and right inner walls of the seat tube 1, and a limiting block 17 is slidably connected to the limiting groove 22. The limiting block 17 is welded to one side of the lifting column 7.

[0031] In some embodiments, the T-shaped rod 5 has a plurality of fixing grooves 18 arranged in a ring, and a square block 19 is welded to the front side of the seat tube 1.

[0032] The placement of block 19 serves a supporting function.

[0033] In some embodiments, the block 19 is provided with a T-shaped locking rod 20, which is engaged with one of the fixing slots 18 among a plurality of fixing slots 18.

[0034] In some embodiments, a second spring 21 is welded between one inner wall of the T-shaped lever 20 and one side of the block 19, and the second spring 21 is movably sleeved on the T-shaped lever 20.

[0035] Limiting holes are provided on block 19, so that the T-shaped lever 20 can only move up and down, thus limiting its movement.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
