Problems solved by technology

Using the plug-in charging method has the following defects: 1. The initial investment cost of the battery is relatively large, which hinders the popularization of electric vehicles to a certain extent; Compared with electric vehicles, it takes too long to recharge energy, which is very inconvenient and far from meeting people's needs
After the locking device is tightened, the unlocking parts engage with each other under the action of its own elastic parts, and it is in an anti-unlocking state, which plays the role of fastening the battery pack; if the locking device is loosened without lifting the anti-unlocking parts, it will cause Damaged locking device parts

Abstract

The invention provides an unlocking device which comprises a jacking mechanism, a screwing mechanism and a motor. The motor is used for driving the screwing mechanism, the jacking mechanism is arranged on the outer side of the screwing mechanism, the screwing mechanism is connected with a mounting plate, and an elastic piece is arranged between the jacking mechanism and the mounting plate. The jacking mechanism can axially move relative to the screwing mechanism, the jacking mechanism is provided with a jacking part, and the height of the highest point of the jacking part is larger than that of the highest point of the screwing mechanism. The unlocking device has a jacking function, can unlock the anti-unlocking device of the locking device, has a screwing function, can achieve locking andunlocking operation of the locking device after the anti-unlocking device is unlocked, also has a torque dynamic real-time detection function, and can analyze and judge the tightening and unlocking processes under the action of a torque sensor.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an unlocking device for performing locking and unlocking operations on a locking device of a battery pack of an electric vehicle. Background technique [0002] With the increasingly serious energy and environmental problems, the country's strong support for new energy, and the increasingly mature power battery technology, electric vehicles have become a new direction for the future development of the automotive industry. However, electric vehicles have the problems of small battery storage energy and unsatisfactory mileage after one charge. At present, the power supply methods of electric vehicle power batteries are generally divided into two modes: plug-in charging with the car and battery replacement, and the plug-in charging mode is further divided into two modes: slow charging and fast charging. Using the plug-in charging method has the following defects: 1. The initial ...
