Patent attributes
A frame lifting mechanism includes a base, a motor, a lead screw, a sliding member, a lifting member and a supporting shaft. The motor is connected to the lead screw, and the lead screw is fastened onto a transmission tube, allowing the transmission tube to move forward and backward while being driven by the lead screw. The sliding member is installed on a sliding track arranged on the base and connected to the transmission tube, allowing the sliding base to actuate with the transmission tube synchronously. A rear end of the lifting base is pivotally attached onto the base for support, and the supporting member uses its two top and bottom ends to be pivotally attached onto the lifting member and the sliding member respectively, allowing the supporting shaft to utilize the movement of the sliding member to drive the lifting member to move upward and downward.
