[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] like Figure 1-2 As shown, the utility model is a height adjustment structure of a battery vehicle seat, comprising a frame 1, wherein the frame 1 is fixedly connected to a fixed tube 2, wherein the upper portion of the fixed tube 2 is communicated with a connecting tube 3, wherein a protective cover 4 is provided at the lower end of the connecting tube 3, wherein a worm 5 is provided at one side of the protective cover 4, wherein a worm wheel 6 meshing with the worm 5 is provided in the protective cover 4, wherein a movable tube 7 is inserted in the middle of the worm wheel 6, wherein the movable tube 7 is movably connected to the connecting tube 3, wherein a threaded rod 8 is inserted in the middle of the movable tube 7, wherein an inner thread matching the threaded rod 8 is provided on the inner wall of the movable tube 7 The threaded rod 8 is fixedly connected to the support rod 10 at the top, and the support rod 10 passes through the connecting tube 3 and is fixedly connected to the seat cushion 11 at the top. When the worm 5 rotates, the worm wheel 6 meshing with the worm 5 also rotates accordingly. Driven by the worm wheel 6, the movable tube 7 starts to rotate. When the movable tube 7 rotates, the threaded rod 8 can move vertically inside the connecting tube 3 through the cooperation between the internal thread 9 on the movable tube 7 and the threaded rod 8. The seat cushion 11 also moves accordingly through the transmission of the support rod 10, so that the height of the seat can be adjusted.

[0022] The support rod 10 and the seat cushion 11 are fixedly connected via a first bolt 12 .

[0023] A clamp 13 is provided above the connecting pipe 3, and a second bolt 14 is inserted into one side of the clamp 13, and a nut 15 is provided on the second bolt 14, and a push rod 16 is inserted into the end of the second bolt 14. The second bolt 14 and the nut 15 are threadedly connected, and the push rod 16 is inserted into the end of the second bolt 14. The arrangement of the push rod 16 makes it easier to rotate the second bolt 14. When the second bolt 14 and the nut 15 are fixedly connected, the clamp 13 can clamp the support rod 10, and the arrangement of the clamp 13 further increases the stability of the seat cushion 11 after it is fixed.

[0024] A connecting rod 17 is inserted into the middle part of the protective cover 4 close to the worm 5. The connecting rod 17 is fixedly connected to the worm 5. The connecting rod 17 is fixedly connected to a rotating block 18 on the side away from the worm 5. The connecting rod 17 and the protective cover 4 are movably connected. The setting of the rotating block 18 makes it easier to rotate the worm 5.

[0025] The outer side of the rotating block 18 is provided with anti-skid patterns 19 , which effectively increase the friction between the palm and the rotating block 18 , thereby making it easier to rotate the rotating block 18 .

[0026] The threaded rod 8 is located in the fixed tube 2, and one end is fixedly connected to the movable plate 20. Four guide rods 21 arranged in a matrix are inserted on the outside of the movable plate 20. Both ends of the guide rods 21 are respectively fixedly connected to the inner wall of the fixed tube 2. The guide rods 21 are movably connected to the movable plate 20. Through the mutual cooperation between the guide rods 21 and the movable plate 20, the threaded rod 8 can be limited, so that the threaded rod 8 can move stably in the vertical direction.

[0027] Specifically, in the utility model, when the rotating block 18 is rotated, the rotating block 18 drives the worm 5 to rotate through the connecting rod 17. When the worm 5 rotates, the worm wheel 6 meshing with the worm 5 also rotates accordingly. Driven by the worm wheel 6, the movable tube 7 starts to rotate. When the movable tube 7 rotates, the threaded rod 8 can move vertically inside the connecting tube 3 through the cooperation between the internal thread 9 on the movable tube 7 and the threaded rod 8. The seat cushion 11 also moves accordingly through the transmission of the support rod 10. At the same time, the internal thread 9 on the movable tube 7 can limit the threaded rod 8, thereby avoiding the displacement of the seat cushion 11 during the use of the electric vehicle. When the second bolt 14 is fixedly connected to the nut 15, the clamp 13 can clamp the support rod 10. The setting of the clamp 13 further increases the stability of the seat cushion 11 after it is fixed.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
