Abstract

The invention discloses an electric push rod. The electric push rod comprises a DC motor, a transmission mechanism and a push rod, wherein the transmission mechanism comprises a main gear in axis connection with the DC motor and a transmission gear connected with the push rod, a plurality of wheel speed sensors are uniformly arranged on the transmission gear at interval, a signal receiver is arranged below the transmission gear, the signal receiver is connected with a controller, the controller controls and is connected with the DC motor, and the wheel speed sensors, the signal receiver and the controller coordinate with each other so as to control the DC motor and further control rotation turns and rotation angle of the transmission gear, thereby enabling the push rod to produce accurateaxial movement stroke. The wheel speed sensors and the signal receiver coordinate so as to calculate rotation turns of the transmission gear, when the transmission gear rotates to the desired turns, the controller controls the DC motor to start or stop.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an electric push rod. Background technique [0002] At present, Chinese patent literature discloses a motor push rod, application publication number (CN 207796016 U), which includes a drive mechanism, a transmission mechanism and a push rod mechanism, the output end of the drive mechanism is connected to the input end of the transmission mechanism, and the The output end of the transmission mechanism is connected to the input end of the push rod mechanism, and it is characterized in that: the input end of the push rod mechanism is a gear clutch mechanism.
