Power-off automatic locking and abnormal-power-off lock preventing device for electric rotating mechanism

Abstract

The invention relates to a power-off automatic locking and abnormal-power-off lock preventing device for an electric rotating mechanism. The power-off automatic locking and abnormal-power-off lock preventing device comprises a rotating unit, a fixed unit, a brake unit, a clutch device and a lock preventing unit. The brake part is assembled on the fixed part and capable of shifting to lock and release the rotating unit; the clutch device is used for controlling shifting of the brake unit; the anti-locking unit is used for automatically preventing the brake unit from shifting when in abnormal power off of a power supply during rotation of the rotating unit. The clutch device driving the brake unit to shift is controlled to apply work through the power supply, and the brake unit is driven to shift to be separated from a fastening state and be released from the rotating unit. On the premise of normal switching operations of the power supply, security effects that the rotating unit of the rotating mechanism can be locked without rotation when the power supply is off, can rotate freely when the power supply is on, and cannot be locked without rotation until the rotation speed of the rotating part is reduced to a set rotation speed value when in abnormal power off during rotation thereof can be achieved.

Description

technical field [0001] The invention relates to an automatic power-off locking and abnormal power-off anti-locking device that can be widely used in beach vehicles, golf carts, four-wheel electric vehicles, and any electric rotating mechanism that needs to have power-off automatic locking and braking. Background technique [0002] General rotating mechanisms (such as: ATVs, golf carts, four-wheeled electric vehicles, and any electric rotating mechanisms that require automatic locking brakes when power is off) are controlled by hand brake auxiliary devices to prevent slippage after the power is turned off. However, the relevant hand brake auxiliary device must rely on the deliberate operation of personnel to produce the brake locking effect. Therefore, it often happens that personnel forget to operate the hand brake auxiliary device after the power is turned off, resulting in the risk of slipping of vehicles and implements. [0003] Therefore, how to develop a kind of by ON, ...

Problems solved by technology

[0004] At the same time, the research and development of using the ON and OFF of the power switch of the rotating mechanism to directly control the brake lock and release lock of the mechanical components of the rotating mechanism must further consider the abnormal power failure of the power supply during the operation of the rotating mechanism to ensure When abnormal power failure occurs (such as storage battery failure, power supply failure and other abnormal control power failure situations), it can prevent the running rotating mechanism from being suddenly locked and braked, and these technologies have not yet been adopted by the relevant technical fields. breakthrough
