Electric push rod

Abstract

The invention discloses an electric push rod which comprises a mounting seat, a transmission assembly arranged on the mounting seat and a motor arranged on the mounting seat and in transmission connection with the transmission assembly, and the motor is electrically connected with a conductive part. In addition, the motor further comprises a rod body, one end of the rod body is connected to the mounting base, a rigid PCB is arranged in the rod body, one end of the rigid PCB extends into the mounting base, a power connection part is arranged on the rigid PCB, and the power connection part abuts against the conductive piece so that the motor can be electrically connected with the rigid PCB. Therefore, the rigid PCB is adopted to replace a traditional flexible PCB, the power connection part is arranged on the rigid PCB, and the original welding procedure between the flexible PCB and the power line is omitted; besides, when the motor is connected to the mounting seat and the mounting seat is connected to one end of the rod body, the conductive piece of the motor can abut against the power connection part on the rigid PCB, then electrical connection between the motor and the rigid PCB is achieved, the structure and process of electrical connection between the motor and the rigid PCB are simplified, and the overall structure of the electric push rod is simplified.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an electric push rod. Background technique [0002] The electric push rod is a linear drive device, which mainly uses the screw nut drive to convert the rotary motion of the motor into the linear motion of the slider. It can be used as an executive machine in various simple or complex technological processes to achieve long-distance control, centralized control or automatic control. At present, electric actuators have been widely used in electric medical beds, electric sofas, electric booth lifting rods, industrial electric lifting systems, etc. [0003] In order to supply power to the motor in the electric push rod, there are mainly two ways to achieve it: the first is to set a power cord in the motor, one end of the power cord is electrically connected to the motor, and the other end is led out through the lead wire assembly and connected to the motor.
