2results about How to "Lower resonance frequency" patented technology

This utility model discloses a wireless controller with automatic magnetic pole positioning function, belonging to the field of wireless controller technology. It includes a controller and a mounting plate. The lower surface of the controller is provided with a sliding groove, and the upper surface of the mounting plate is provided with a shock-absorbing component. In this utility model, by providing the shock-absorbing component, during the movement of the controller, the travel block slides within the travel groove under the limitation of the limiting rod. Under the action of the shock-absorbing spring, the movement distance of the travel block is controlled, thereby controlling the up-and-down vibration frequency of the controller under the action of the connecting rod and the damping shock absorber. This realizes the shock-absorbing function of the wireless controller, improves the vibration reduction effect during operation, reduces the resonance frequency of the wireless controller, further reduces the possibility of loosening of internal components during operation, and improves the service life and stability of the wireless controller.

This utility model provides an automatic feeding device for steel shot production, relating to the field of automatic feeding technology. It includes: a feeding mechanism, a collecting mechanism at the top of the feeding mechanism, a support frame, a main board at the top of the support frame, a flexible hopper at the lower end of the main board, a rubber vibration damper at the front end of the main board, and a side plate on the left side of the rubber vibration damper. This utility model designs the feeding hopper as a split structure, consisting of a main board, a side plate, and a second side plate. Rubber vibration dampers are installed between the main board and the side plates, and between the side plates themselves. When the feeding hopper is severely worn by the steel shot, it is not necessary to replace the entire feeding hopper; only the severely worn parts need to be replaced individually. Furthermore, the rubber vibration dampers can reduce the resonance frequency transmitted from the main board to the side plate, and reduce the resonance frequency transmitted from the first side plate to the second side plate, thereby reducing noise.
