[0036] In the present embodiment, as shown in Figure 1 , Figure 4 and Figure 5As shown, the base 10 comprises a support frame 100, a driving member 200, a transmission shaft 300, a lifting seat 400 and a thrust member 500. The driving member 200 comprises a driving body 210 and a housing 220, the driving body 210 is arranged in the housing 220, and the housing 220 is arranged on the support frame 100. The transmission shaft 300 is in transmission connection with the driving body 210. The lifting seat 400 is slidingly arranged on the support frame 100, and the lifting seat 400 is connected with the transmission shaft 300. The driving body 210 can drive the transmission shaft 300 to move, so that the transmission shaft 300 drives the lifting seat 400 to move up and down.

In some embodiments, the thrust member 500 can be but is not limited to a thrust bearing, a thrust washer, a check ring, a thrust ring, etc.

[0037] In operation, the driving body 210 of the driving member 200 drives the transmission shaft 300 to move, so that the transmission shaft 300 drives the lifting seat 400 to move up and down. The lifting seat 400 and the functional devices on the lifting seat 400 can be the load of the driving member 200, and the gravity of these loads directly acts on the housing 220 through the transmission shaft 300 and the thrust member 500, avoiding the load of the lifting seat 400 acting on the driving body 210 through the transmission shaft 300. The driving body 210 is arranged in the housing 220, so the load of the lifting seat 400 does not affect the driving body 210, and the service life of the driving member 200 can be prolonged.

[0038] In some embodiments, the support frame 100 is provided with a first sliding groove and a second sliding groove on two sides respectively, and the lifting seat 400 is slidingly arranged in the first sliding groove and the second sliding groove on two sides, so that the lifting seat 400 can stably slide along the support frame 100, and the stability of the entire structure is increased.

The support frame 100 is placed in a vertical direction, and the lifting seat 400 moves up and down relative to the support frame 100.

[0040] In this embodiment, please refer to Figure 2 and Figure 3The lifting seat 400 comprises a lifting support 420 and a sliding cylinder 430. The lifting support 420 is slidably arranged in the first sliding groove and the second sliding groove.

The transmission shaft 300 is arranged in the sliding cylinder 430, so that the transmission shaft 300 rotates in the sliding cylinder 430, avoiding the contact between the transmission shaft 300 and the wire and affecting the rotation of the transmission shaft 300. Moreover, the rotation of the transmission shaft 300 will not affect the wiring mode of the wire, and the risk of scratching the wire by the transmission shaft 300 can also be avoided.

[0041] It can be understood that the sliding cylinder 430 is arranged at one side of the lifting support 420. In some embodiments, the lifting support 420 is a plate structure.

[0042] In some embodiments, the driving member 200 is a motor, and the driving body 210 is a motor body. The transmission shaft 300 comprises a screw rod 310.

The transmission member 410 moves synchronously with the lifting seat 400. The output shaft drives the screw rod 310 to rotate, so as to drive the transmission member 410 and the lifting seat 400 to move up and down. Through the cooperation of the motor and the screw rod 310, the lifting seat 400 can be better driven to move up and down. The transmission member 410 can be but is not limited to a nut. In some embodiments, through the cooperation of a belt wheel and a belt, the rotary motion of the motor can also be converted into linear motion.

[0043] In some embodiments, the base 10 further comprises a coupling 600. The two ends of the coupling 600 are respectively connected with the output shaft and the screw rod 310.

The thrust bearing is arranged between the housing 220 and the coupling 600, so that the force of most of the load of the lifting seat 400 is transmitted to the housing 220 through the thrust bearing, so that the output shaft only transmits rotary torque, and the output shaft will not be subjected to radial force. During work, the force generated by the lifting seat 400 and the functional devices thereon acts on the housing 220 through the screw rod 310, the coupling 600 and the thrust member 500, avoiding that the load of the lifting seat 400 directly acts on the inside of the motor, prolonging the service life of the motor, and enabling the motor to be used in a large-load scene.
