The base assembly 5 serves to support the entire seat. In order to meet the requirements of different users or the same user on different heights of the cushion assembly 1 in different states, the seat lifting assembly 3 is fixedly mounted on the base assembly 5 and is used for adjusting the height of the cushion assembly 1 in the vertical direction. As the child grows, there is a greater demand for the size of the seating surface, and thus it is necessary to adjust the front-rear position of the seat cushion assembly 2 so that the child enters a learning state in an optimal sitting posture.
The cushion driving assembly 4 comprises a motor assembly 41, a screw nut 42, a solid screw 43, a fixed pipe 44, a connecting piece 45 and a transmission connecting piece; the screw nut 42 is fixedly connected with the connecting piece 45, the connecting piece 45 is fixedly connected with the bottom of the seat cushion assembly 2, the motor assembly 41 drives the solid screw 43 to rotate through a transmission connecting piece connected with the driving end, and the solid screw 43 drives the screw nut 42 and the connecting piece 45 to linearly move. The seat cushion assembly 2 is fixedly coupled with the lead screw nut 42, and thus, when the lead screw nut 42 performs a linear motion, the seat cushion assembly 2 is moved forward and backward.
There are various ways in which the motor assembly 41 drives the solid screw 43 to rotate.
The first transmission mode is as follows: the transmission connecting piece is a worm gear box 46a, the motor assembly 41 drives the worm gear box 46a to operate, and the worm gear box 46a drives the solid screw 43 to rotate. The solid screw 43 rotates to drive the screw nut 42 to move back and forth, thereby driving the cushion assembly 2 to move back and forth.
Further, the seat cushion drive assembly 4 is detachably mounted to the seat lift assembly 3 by a seat cushion mount 31. The connecting piece 45 is in clearance fit with the fixed pipe 44; the connecting piece 45 is connected to the spindle nut 42.
