Embodiment

[0021] Please refer to Figures 1-5 As shown, a two - speed tilting adjustment seat chassis integrated with a spring includes a bottom plate 2, characterized in that: an activity seat 6 is provided below the bottom plate 2, a tapered tube installation hole 12 is provided at the center of the activity seat 6, a connecting vertebral tube 11 is provided below the tapered tube installation hole 12, a long waist hole is provided on one side of the tapered tube installation hole 12, a elastic force adjustment mechanism is provided below the long waist hole, and a tilting adjustment mechanism is provided on one side inside the activity seat 6. The tilting adjustment mechanism includes an adjustment plate 19, an adjustment rod 3 is installed inside the adjustment plate 19, one end of the adjustment rod 3 passes through the bottom plate 2, the activity seat 6 and the adjustment plate 19 and cooperates with the activity seat 6. A lifting torsion spring 14 is installed on one side of the adjustment plate 19, and a control spring 17 is provided on the other side. One end of the control spring 17 is connected with a locking pin 15. This design can provide a flexible tilting adjustment function, and at the same time maintain the comfort of the seat through the elastic force adjustment mechanism. The design of the locking pin 15 ensures the stability of the seat after adjustment, avoiding unnecessary shaking or movement.

[0022] In this embodiment, the locking pin 15 is composed of a cylindrical section 20 and a square locking section 21. The cylindrical section 20 is associated with the control spring 17. A first - gear pin hole is provided on one side of the bottom plate 2, and a second - gear pin hole is provided below the first - gear pin hole. Both the first - gear pin hole and the second - gear pin hole are associated and cooperate with the locking pin 15. Both the first - gear pin hole and the second - gear pin hole are square groove holes. Through the combined use of pin holes with different shapes and the locking pin 15, a multi - gear tilting adjustment function is realized, increasing the flexibility and adaptability of use.

[0023] In this embodiment, installation grooves 22 are provided on both sides of the long waist hole of the activity seat 6. The installation grooves 22 reduce the contact surface with the compression spring 8 and reduce the overall height, thereby effectively reducing the size of the entire product.

[0024] In this embodiment, a first screw 16 is provided at the connection between the locking pin 15 and the control spring 17 and is fixed by the first screw 16. A second screw 18 is provided at the connection between the adjustment plate 19 and the adjustment rod 3 and is fixed by the second screw 18. The use of screws provides a reliable fixing method, ensuring the accuracy and long - term stability of the adjustment mechanism, and reducing the wear problem caused by long - term use.

[0025] In this embodiment, a rivet 4 is provided at the connection between the center of the movable seat 6 and the center of the bottom plate 2. A bushing 5 is provided at the connection between the rivet 4 and the movable seat 6. Both the rivet 4 and the bushing 5 are common products on the market and can be directly purchased. The use of the rivet 4 enhances the connection strength between the movable seat 6 and the bottom plate 2, while the bushing 5 plays a buffering role, reducing friction and noise during movement, and improving the service life and riding comfort of the seat.

[0026] In this embodiment, the elastic force adjusting mechanism includes an adjusting nut 10. A bowl-shaped gasket 9 is provided at the center of the inner wall of the adjusting nut 10. One end of the bowl-shaped gasket 9 is provided with a compression spring 8. A spring sheath 7 is provided outside the compression spring 8. A fixing screw 1 is provided above the bottom plate 2. One end of the fixing screw 1 sequentially passes through the compression spring 8, the bowl-shaped gasket 9, and the adjusting nut 10 and is connected to the adjusting nut 10, which can precisely control the elasticity and hardness of the seat, meet the needs of different users, and improve the overall riding experience.

[0027] The implementation principle of this embodiment is as follows: First, if the user feels that the seat is too hard or needs more support, the elastic force adjusting mechanism can be used to increase the elasticity of the seat. This involves tightening or loosening the adjusting nut 10 located below the fixing screw 1 above the bottom plate 2. Through the action of the compression spring 8 and the bowl-shaped gasket 9, the adjusting nut 10 can adjust the magnitude of the pressure, thereby changing the hardness and elasticity of the seat. To ensure the stability of the seat after adjustment, the user will use the locking pin 15 to lock the adjusted reclining angle. By manually pulling out the adjusting rod 3 outward, the adjusting rod 3 pulls the adjusting plate 19, which in turn drives the control spring 17. Then, by rotating the adjusting rod 3, the adjusting rod 3 sequentially drives the adjusting plate 19 and the lifting torsion spring 14 to rotate, thereby raising the height of the locking pin 15. Finally, by pushing the adjusting rod 3 inward, the locking pin 15 is inserted into the corresponding pin hole to complete the first or second gear reclining adjustment according to the user's selection.
