Abstract
Disclosed is a drive device, comprising a motor assembly, a transmission assembly, a guide rail assembly and a switch assembly; the motor assembly comprises a housing and a motor provided on the housing; the transmission assembly comprises a worm and a worm nut, the worm being in transmission connection with the motor, and the worm nut being sleeved on the worm and making a linear reciprocating motion between a first limit position and a second limit position; the guide rail assembly is movably provided on the housing, and the guide rail assembly is provided with a linear guide portion for guiding the worm nut; the switch assembly comprises a first switch and a second switch, and the switch assembly is provided close to the motor and is electrically connected to the motor; when the worm nut moves to the first limit position, the first switch comes into contact with the worm nut so as to stop the operation of the motor and prevent the worm nut from exceeding the first limit position; and when the worm nut moves to the second limit position, the guide rail assembly moves in an axial direction of the worm and comes into contact with the second switch so as to stop the operation of the motor and prevent the worm nut from exceeding the second limit position.
