[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The vehicle seat support assembly structure is installed with a seat body, a drive box, a motor, a driving shaft, a driven shaft, a driving wheel, a driven wheel, a rotating column, a lifting sleeve, a guide sleeve and a guide rod. The motor drives the driving wheel to rotate through the driving shaft. The driving wheel and the driven wheel are connected by a belt, which drives the driven wheel to rotate, so that the rotating column rotates. The outer side of the top of the rotating column is provided with an external thread, and the inner wall of the lifting sleeve is provided with an internal thread matching the external thread, so that the lifting sleeve can move up and down, thereby driving the seat body to move up and down to adjust the height to meet different riding needs.

The movable part is connected to the four corners of the bottom of the shock-absorbing support through rigid springs. When the seat body is in use, if vibration occurs, the vibration force causes the electric slide rail to press down the movable part, and the movable part squeezes the rigid spring. The rigid spring absorbs part of the vibration force through its expansion and contraction and rebound, thereby playing a role in shock absorption and buffering. The rigid spring has a large stiffness coefficient and high hardness, so that its shaking range is small and its stability is better. At the same time, the bottom of the movable part is connected to the bottom end of the shock-absorbing support through an elastic ball, and the elastic ball is made of rubber to further increase the shock absorption performance.

[0019] (3) The vehicle seat support assembly structure is installed with a fixed frame, and mounting holes are set at the four corners of the fixed frame to facilitate fixed connection with the drive box. Hollow parts are evenly set around the fixed frame to reduce the weight of the fixed frame and ensure its support. Support reinforcement ribs are fixed at the central position of the fixed frame to improve the structural strength of the fixed frame, making it not easy to break or damage, thereby extending the service life of the fixed frame.

The rigid spring 701 has a large stiffness coefficient and high hardness, so that its shaking range is small and the stability is better. At the same time, the bottom of the movable part 702 is connected to the bottom end of the shock absorbing support 7 through an elastic ball 703, and the elastic ball 703 is made of rubber to further increase the shock absorption performance;

[0030] The hollow portion 9 can reduce the weight of the fixing frame 12 while ensuring its support. The supporting reinforcement ribs 11 are convenient for improving the structural strength of the fixing frame 12, making it less likely to break or be damaged, thereby extending the service life of the fixing frame 12.

[0031] The top of the fixed frame 12 is fixed with the driving box 3, and the four corners of the fixed frame 12 are provided with mounting holes 13. The bottom of the driving box 3 is provided with reserved holes corresponding to the mounting holes 13. The inner walls of the mounting holes 13 are provided with sealing rings to facilitate the fixed installation and disassembly of the driving box 3. At the same time, the sealing rings are conducive to increasing the tightness when connecting and fixing;

[0032] A driving shaft 18 is provided at the central position inside the driving box 3, a motor 5 is fixed at the central position on the top of the driving box 3, and the output end of the motor 5 is connected to the driving shaft 18, driven shafts 17 are provided at both ends inside the driving box 3, and the top end of the driven shaft 17 passes through the driving box 3 and extends to the outside of the driving box 3, a rotating column 16 is fixed to the top end of the driven shaft 17, and a lifting sleeve 6 is provided on the upper sleeve of the rotating column 16, and the top end of the lifting sleeve 6 is fixedly connected to the bottom of the seat body 4, a driving wheel 19 is provided on the driving shaft 18, and a driven wheel 20 is provided on the driven shaft 17, and the driven wheel 20 is connected to the driving wheel 19 through a belt, the outer side of the rotating column 16 is provided with an external thread, and the inner wall of the lifting sleeve 6 is provided with an internal thread matching the external thread;

[0034] A guide sleeve 14 is fixed on the driving box 3 on one side of the lifting sleeve 6, and a guide rod 15 is arranged inside the guide sleeve 14. The top of the guide rod 15 is fixedly connected to the bottom of the seat body 4. The guide rod 15 is an inverted "T"-shaped structure, and both ends of the bottom of the guide rod 15 are provided with a limit block 21;

[0035] When the seat body 4 is raised or lowered, the guide rod 15 slides in the guide sleeve 14 to play a guiding role. Both ends of the bottom of the guide rod 15 are provided with limit blocks 21 to prevent the guide rod 15 from slipping off.

[0036] The specific model specifications of the motor 5 and the electric slide rail 2 need to be determined by selection calculation based on the specification parameters of the device. The selection calculation method is existing technology, so it will not be described in detail.

[0037] Working principle: When in use, the electric slide rail 2 is fixed in the car by installing the panel 10 and the fixing bolts 1, and then the drive box 3 is connected and fixed to the fixing frame 12. The fixing frame 12 is evenly provided with hollow parts 9 around it, which can not only reduce the weight of the fixing frame 12, but also ensure its support. A "M"-shaped support reinforcement rib 11 is fixed at the central position of the fixing frame 12, which is convenient for improving the structural strength of the fixing frame 12, making it not easy to break and damage, and extending the service life of the fixing frame 12. When the height of the seat body 4 needs to be adjusted, the motor 5 drives the driving wheel 19 to rotate through the driving shaft 18. The driving wheel 18 and the driven wheel 20 are connected by a belt, which drives the driven wheel 20 to rotate, so that the driven shaft 17 drives the rotating column 16 to rotate. The outer side of the top of the rotating column 16 is provided with an external thread, and the inner wall of the lifting sleeve 6 is provided with an internal thread matching the external thread. The lifting sleeve 6 can move up and down, thereby driving the seat body 4 to move up and down to adjust the height to meet different riding needs. When the seat body 4 is raised or lowered, the guide rod 15 slides in the guide sleeve 14 to play a guiding role. Both ends of the bottom of the guide rod 15 are provided with limit blocks 21 to prevent the guide rod 15 from slipping. When the seat body 4 is in use, if vibration occurs, the vibration force prompts the electric slide rail 2 to press down the movable part 702, and the movable part 702 squeezes the rigid spring 701. The rigid spring 701 absorbs part of the vibration force through its expansion and contraction rebound to play a shock absorbing and buffering role. The rigid spring 701 has a large stiffness coefficient and high hardness, so that its shaking range is small and the stability is better. At the same time, the bottom of the movable part 702 is connected to the bottom end of the inside of the shock absorbing support 7 through an elastic ball 703. The elastic ball 703 is made of rubber to further increase the shock absorbing performance.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
