Multi-purpose screw telescopic transmission mechanism with motor and magnetic encoder, and bracket thereof

A multi-purpose screw telescopic transmission mechanism with a motor and a magnetic encoder, and a bracket thereof, wherein the screw telescopic transmission mechanism comprises

• a main machine and a rotating bracket;
• the main machine is mounted on the rotating bracket and is configured to drive an external part to move back and forth, and the rotating bracket is configured to support the main machine and adjust an angle of the main machine;
• the main machine comprises a first motor, a lead screw, a nut, a mounting bracket, and sliding rods;
• a rotating shaft of the first motor is connected to one end of the lead screw through a coupling, the nut is mounted on the lead screw, the mounting bracket is mounted on the nut, a sliding rod is disposed on each of two sides of the mounting bracket, and the external part is mounted on the mounting bracket;
• a magnet is further disposed on the mounting bracket, a first Hall PCB and a second Hall PCB are further disposed on a moving path of the mounting bracket and are configured to set a starting point and an ending point respectively, and the first Hall PCB and the second Hall PCB are configured to sense a motion process of the magnet, so as to set a maximum stroke of motion of the mounting bracket;
• and
• the first motor drives the lead screw to rotate forward and backward to drive the nut to move back and forth, thereby driving the external part mounted on the mounting bracket to move back and forth.
