[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 9 As shown, an electric bicycle seat adjustment device includes an adjustment seat 2, an adjustment rod 5, and a connecting seat 1. The adjustment seat 2 is fixed to the frame and is U-shaped. Adjustment grooves 21 are symmetrically arranged on both sides of the adjustment seat 2. Each adjustment groove 21 includes a sliding groove 212 and several height grooves 211 connected to the sliding groove 212 and having different heights. The several height grooves 211 with different heights allow for different height adjustments. The adjustment rod 5 is fixed to the bottom of the connecting seat 1, while the top of the connecting seat 1 is fixedly connected to the seat. The connecting seat 1 is also located inside the seat and is movably inserted into the adjustment seat 2, thus limiting the axial movement of the adjustment rod 5. The adjustment rod 5 is also movably inserted into the adjustment groove 21. The adjustment rod 5 switches between the several height grooves 211 via the sliding groove 212 to adjust the height and fore-aft position of the seat.

[0023] During adjustment, the seat cushion is pulled upwards, causing the adjusting rod 5 to move upwards from the height groove 211 and into the sliding groove 212. Then, it moves back and forth within the sliding groove 212 and moves to the corresponding height groove 211 to achieve switching between different height grooves 211. The sliding groove 212 is set in the horizontal direction, and the height groove 211 is set in the vertical direction. The height groove 211 and the sliding groove 212 are perpendicular to each other. The height groove 211 can not only adjust the height of the adjusting rod 5, but also limit the adjustment rod 5 to prevent it from moving back and forth during use.

[0024] The connecting seat 1 is L-shaped and symmetrically located at both ends of the adjusting rod 5. The connecting seat 1 has a connecting hole 13, which is connected to the nut 42 inside the seat cushion via a screw 41. The L-shaped connecting seat 1 is made of stamped steel plate, ensuring both strength and low cost.

[0025] The connecting seat 1 and the adjusting seat 2 form a slide rail structure, which can slide freely back and forth.

[0026] To prevent the adjusting rod 5 from moving freely up and down within the height groove 211, a tension spring 3 is also included. The two ends of the tension spring 3 are fixed to the adjusting seat 2 and the connecting seat 1, respectively, and the spring force presses the adjusting rod 5 firmly within the height groove 211. The tension spring 3 uses its elasticity to position the adjusting rod 5, preventing free movement of the adjusting rod 5 and the seat cushion. The adjusting seat 2 has a lower hook groove 26, and the connecting seat 1 has an upper hook groove 14. The upper hook groove 14 and the lower hook groove 26 are respectively connected to the hooks at both ends of the tension spring 3.

[0027] To increase the strength of the adjusting seat 2, a reinforcing flange 24 is provided on the adjusting seat 2, which is positioned opposite to the connecting seat 1. The reinforcing flange 24 not only increases the strength of the adjusting seat 2 but also increases the contact area between it and the connecting seat 1, making it less prone to cracking between the connecting seat 1 and the adjusting seat 2. The adjusting seat 2 is made of stamped steel plate, which is inexpensive and has high strength.

[0028] The adjusting rod 5 is equipped with retaining rings at both ends, and the retaining rings are located on the outside of the connecting seat 1, so that the adjusting rod 5 will not fall off the connecting seat 1, which facilitates the processing and installation of the adjusting rod 5.

[0029] The height and fore-aft position of the seat can be adjusted according to the user's height to improve comfort. It is also easy to adjust, has a simple structure, and is inexpensive.

[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
