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

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a student seat lifting device with height memory function, including: a seat body 1; four support legs 101 sliding on the seat body 1; two locking seats 201 symmetrically welded on the seat body 1; two locking seats 201 symmetrically welded on the four support legs 101; all four locking seats 201 are concave structures; bases 202 are locked into the two lower locking seats 201; guide rods 203 are symmetrically welded to the upper surface of the bases 202. The base 202 and the force-bearing seat 204 slide on the upper part of the lifting assembly 2. The force-bearing seat 204 is engaged with the two upper engagement seats 201. The four engagement seats 201 are connected with locking seats 207. Under the locking action of the locking seats 207, the base 202 and the force-bearing seat 204 are in a limited state. When disassembling and maintaining the lifting assembly 2, the locking seat 207 can be pulled upward and pulled out directly. Then, the base 202 and the force-bearing seat 204 can be pulled to the right to complete the disassembly. The disassembly is convenient and quick, which facilitates the maintenance of the lifting assembly 2.

[0031] The base 202 has a motor 205 fixed on its upper surface. The output shaft of the motor 205 has a threaded rod 206 fixed on it. The threaded rod 206 is threadedly connected to the support seat 204. When adjusting the seat height, the motor 205 is driven to rotate. The motor 205 drives the threaded rod 206 to rotate. Under the threaded drive of the threaded rod 206, the height of the support seat 204 can be adjusted, thus satisfying the height adjustment of the seat.

[0032] Both the base 202 and the force-bearing seat 204 are "I" shaped structures. The left end faces of both the base 202 and the force-bearing seat 204 are polished. After polishing, the left end faces of both the base 202 and the force-bearing seat 204 are arc-shaped structures. When the base 202 and the force-bearing seat 204 are snapped into the snap-fit ​​seat 201, the arc-shaped part can guide the smoothness of the snap-fit ​​between the base 202 and the force-bearing seat 204 and the snap-fit ​​seat 201, thereby improving the assembly efficiency.

[0033] Each support leg 101 has an anti-slip pad 102 attached to one end below it. The anti-slip pad 102 has a rectangular box-shaped structure and is made of rubber. The anti-slip pad 102 can improve the anti-slip effect of the seat. The rectangular box-shaped structure of the anti-slip pad 102 can expand the adhesion area between the anti-slip pad 102 and the support leg 101, thereby improving the stability of their adhesion.

[0034] The seat body 1 is equipped with a touch screen 302, the motor 205 is equipped with an encoder 301, and the base 202 is fixed with a control box 3. The control box 3 is equipped with a microprocessor and a memory module, which are electrically connected. The microprocessor is also electrically connected to the encoder 301 and the touch screen 302.

[0035] Example 2, based on Example 1, such as Figures 1 to 6As shown, the lower end of the locking seat 207 is polished, and after polishing, the lower end of the locking seat 207 has an arc-shaped structure. When the locking seat 207 is inserted into the snap-fit ​​seat 201, the smoothness of the insertion between the locking seat 207 and the snap-fit ​​seat 201 can be improved under the guidance of the arc-shaped part.

[0036] The working principle of this embodiment is as follows: In use, first slide the four support legs 101 onto the seat body 1 to a suitable position, utilizing the rectangular box-shaped anti-slip pads 102 of rubber material attached below to enhance seat stability. When installing the lifting assembly 2, insert the "I"-shaped base 202 into the two lower concave locking seats 201, and simultaneously insert the force-bearing seat 204 into the two upper locking seats 201. The arc-shaped polished structure on the left end face of the base 202 and the force-bearing seat 204 guides smoother engagement. Then, insert the locking seat 207 into the four locking seats 201; its lower arc-shaped design facilitates insertion, allowing the base... The seat 202 and the force-bearing seat 204 are in a limited position. When adjusting the seat height, the touch screen 302 on the seat body 1 is operated. After receiving the instruction, the microprocessor in the control box 3 drives the motor 205 on the base 202. The motor 205 drives the threaded rod 206 to rotate, so that the force-bearing seat 204 slides along the guide rod 203 to achieve height adjustment. The encoder 301 can provide feedback on position information, and the memory module can store commonly used heights. When it is necessary to disassemble and repair the lifting component 2, the locking seat 207 can be pulled out by lifting upwards, and the base 202 and the force-bearing seat 204 can be pulled to the right for quick disassembly. The operation is convenient.
