Rotating locking and unlocking device

Abstract

The invention provides a rotating locking and unlocking device. The rotating locking and unlocking device comprises a rotating unlocking body, wherein the rotating unlocking body comprises a locking and unlocking assembly, a linear driving assembly and a transmission structure, the locking and unlocking assembly is used for abutting against a locking mechanism and providing a pushing force for unlocking the locking mechanism and is used for providing torque for driving the locking mechanism to rotate, the transmission structure is used for connecting the linear driving assembly and the lockingand unlocking assembly and is used for converting linear movement into rotating movement so as to enable the linear driving assembly to drive the locking and unlocking assembly through the transmission structure to act on the locking mechanism. The rotating locking and unlocking device has the advantages that the structure is ingenious, the design is reasonable, the linear driving device is adopted as a power source, a speed reducing structure is not needed, the overall cost is effectively reduced, meanwhile, the transmission mode is accurate and reliable, the load requirement for rapid battery change of a new energy vehicle is met, and popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the field of quick battery replacement, and in particular relates to a rotation locking device. Background technique [0002] With the increasing use of various types of new energy vehicles such as electric vehicles and hybrid vehicles, technologies related to quick battery replacement have become more and more people's attention and research topics. [0003] Although a variety of power replacement methods have appeared at present, such as using the tightening gun to tighten the shaft for tightening, locking or unlocking, although the performance is reliable and the control is flexible, the servo motor is often used to cooperate with the reduction mechanism to realize the rotation drive, but the horizontal size of this type of structure is different from that of The size in the vertical direction is huge, and the price of using a small motor is high, and the output torque is limited at the same time. [0004] In this regard, t...
