The invention belongs to the technical field of height adjustment, and discloses a height adjusting mechanism which comprises a base, a ball screw, a ball nut, a driving assembly, a controller, a first limiting switch and a second limiting switch. The ball nut is rotationally arranged in the base and arranged in the circumferential direction of the ball screw in a sleeving mode, the driving assembly is arranged on the base, the output end of the driving assembly is connected with the ball nut, the controller is arranged in the base, the controller is provided with a current protection module, and the first limiting switch and the second limiting switch are arranged at the two opposite ends of the base. The driving assembly, the first limiting switch and the second limiting switch are electrically connected with the controller. According to the height adjusting mechanism, the driving assembly can stop running when the ball screw ascends or descends to the limiting position, the situation that the ball screw is damaged due to the fact that the ball screw exceeds the adjusting range is avoided, the service life is guaranteed, the later maintenance cost is reduced, and overload damage to the driving assembly can be avoided.
本发明属于高度调节技术领域,公开了一种高度调节机构,包括基座、滚珠丝杆、滚珠丝母、驱动组件、控制器、第一限位开关以及第二限位开关,滚珠丝杆穿设在基座上且能够相对基座上升或者下降,滚珠丝母转动设置在基座内并套设在滚珠丝杆的周向上,驱动组件设置在基座上,驱动组件的输出端与滚珠丝母连接,控制器设置在基座内,控制器设置电流保护模块,第一限位开关以及第二限位开关设置在基座的相对两端,驱动组件、第一限位开关以及第二限位开关与控制器电连接。该高度调节机构,能够在滚珠丝杆上升或者下降到极限位置时停止驱动组件运行,避免滚珠丝杆超出调节范围而损坏,保证了使用寿命,减少后期维护成本,而且能够避免驱动组件过载损坏。
