Problems solved by technology

[0002] The existing electric telescopic rod technology generally adopts a screw-screw connection mechanism. The telescopic stroke is limited by the length of the screw, and the telescopic is relatively small. The linear speed of the threaded screw with the rise and fall is relatively slow, and it cannot meet the requirements of large stroke and large telescopic ratio. Based on the above shortcomings of the threaded screw telescopic rod, this embodiment proposes a new type of large-stroke electric telescopic rod structure

Abstract

The invention mainly relates to a mechanical device of a large-stroke electric telescopic rod. The large-stroke electric telescopic rod is characterized in that the structure is simple and reliable, the stroke is large, the telescopic ratio is large, and the mechanical device is suitable for large-stroke and medium-and-small-thrust linear telescopic mechanisms. By means of the mechanical device, amotor is used for providing power, friction force provided by a friction wheel and a driven wheel is used for driving a flexible shaft to do linear motion, and the flexible shaft then drives the telescopic rod to do linear telescopic motion. By means of the mechanical device, a stroke switch is used for controlling the stroke of the telescopic rod, when the telescopic rod completes contracting orstretching, the stroke switch can be triggered, the pin level changes of the stroke switch are caused, after the level changes are obtained through a controller, the motor can be controlled to stop moving, and the telescopic rod can do normal stretching and contacting motion.

Description

technical field [0001] Embodiments of the present disclosure mainly relate to a mechanical device of a large-stroke electric telescopic rod. Background technique [0002] The existing electric telescopic rod technology generally adopts a screw-screw connection mechanism. The telescopic stroke is limited by the length of the screw, and the telescopic is relatively small. The linear speed of the threaded screw with the rise and fall is relatively slow, and it cannot meet the requirements of large stroke and large telescopic ratio. Based on the above shortcomings of the threaded screw telescopic rod, this embodiment proposes a new structure of a large-stroke electric telescopic rod. This embodiment has the advantages of large stroke ratio, simple structure, high reliability and small volume. Contents of the invention [0003] Embodiments of the present disclosure provide a mechanical structure and a control method of a large-stroke electric telescopic rod. The technical sch...
