A control device for lift mechanisms

Abstract

The invention discloses a control device for a lifting mechanism, which belongs to the technical field of lifting control, and comprises a mounting box installed on the lifting mechanism, a circuit board, and a paddle assembly partially penetrated into the mounting box. The circuit board includes a control device for lifting and lowering. Elastic self-resetting lift switch, the paddle assembly is toggled to close the lift switch, the two side walls of the paddle assembly are provided with limit parts, the limit part and the switch are misplaced along the depth direction of the paddle assembly, the limit part It can move vertically with the paddle assembly, and there are stoppers on the two side walls of the installation box; the paddle assembly includes a free state and a toggle state. In the free state, the stopper vertically stops the limit portion, and the dial In the moving state, the paddle assembly rotates with the contact point of the stopper and the limiter as the fulcrum. The stopper and the stopper structure of the stopper and the limiter have higher limiter strength, better limiter effect, simple structure and easy assembly. Low precision requirements reduce processing difficulty.

Description

【Technical field】 [0001] The invention relates to the technical field of lifting control, in particular to a control device for a lifting mechanism. 【Background technique】 [0002] With the improvement of living standards, smart homes are more and more popular with the public. Automatic lifting platforms are commonly used power components in smart homes. Automatic lifting platforms generally use motors as power sources, and control mechanical equipment through control boxes to adjust the lifting platform. To enable the lifting platform to be adjusted smoothly between high and low positions, the control box is equipped with an up switch and a down switch. The adjustment principle is: touch the up switch, and the micro-control unit of the circuit board in the control box sends an "up" command to the control box , the control box controls the motor to rotate forward, and drives the mechanical equipment to do the "up" action; touch the down switch, the micro control unit of the ...

AI Technical Summary

Problems solved by technology

[0003] The existing control device includes an installation box and a paddle assembly located in the installation box. The lifting switch is touched by flipping the paddle assembly. The previous paddle shifting structure is matched by the shaft hole, so that the rotating shaft is in the shaft hole. Rotation is used to realize the shifting of the paddle, and when the paddle assembly is flipped, the limit of the rotation stroke is only realized by the shaft hole; and the shaft hole matching structure has high requirements on the matching size and surface smoothness of the shaft and the shaft hole. Both the surface of the shaft and the shaft hole need to be polished, otherwise it is easy to get stuck or loose
