1. A lifting structure, comprising:
a lifting assembly comprising two first links, two second links, and two seats; each of two first links comprising at least one first connecting arm each having a first end and a second end, a first gear structure provided on the first end of each of the at least one first connecting arm; each of the two second links comprising at least one second connecting arm each having a third end and a fourth end, a second gear structure provided on the third end of each of the at least one second connecting arm; the first gear structure of one of the two first links engaged with the first gear structure of the other one of the two first links, the second gear structure of one of the two second links engaged with the second gear structure of the other one of the two second links;
the second end rotatably connected to the fourth end through one of the two seats; and
a driving assembly configured to drive the two seats to move toward or away from each other, thereby causing the third end to be lifted or lowered relative to the first end;
wherein the driving assembly comprises a motor, a screw bolt, and a mounting bracket; the screw bolt comprises a fifth end and a sixth end, an output shaft of the motor is connected to the fifth end through the coupling; the screw bolt passes through the two seats; the motor is configured to drive the screw bolt to rotate, thereby causing the two seats to move toward or away from each other;
wherein the mounting bracket comprises a first mounting plate, a second mounting plate, a third mounting plate, and a fourth mounting plate connected in that order; the first mounting plate and the third mounting plate are connected to two ends of the second mounting plate, the first mounting plate and the third mounting plate protrude vertically from a same surface of the second mounting plate, and are parallel to each other, the first mounting plate is located between the second mounting plate and the motor; the fourth mounting plate extends vertically from the third mounting plate away from the first mounting plate; the first mounting plate, the second mounting plate, and the third mounting plate cooperatively form a receiving cavity, the coupling is partially received in the receiving cavity; the motor is placed on a side of the first mounting plate away from the second mounting plate; the output shaft passes through a hole of the first mounting plate and further extends into the receiving cavity; the fourth mounting plate is connected to one of the seats close to the motor.
