A battery quick change device for a passenger car

Abstract

The invention provides a quick cell changing device for a passenger vehicle. The quick cell changing device comprises a driving cell, a fixing device, a cell plate, a vehicle body plate and a quick changing mechanism, wherein clamping and fastening structures are arranged at two opposite ends of the driving cell; the fixing device is mounted on a vehicle frame of the passenger vehicle, and comprises two lock seats which are oppositely arranged; the cell plate comprises a first supporting plate and cell positioning blocks which are arranged at two opposite ends of the first supporting plate and are connected with the driving cell in an inserting manner; the vehicle body plate comprises a second supporting plate and vehicle body positioning blocks which are arranged at two opposite ends of the second supporting plate and are connected with the lock seats in an inserting manner; the quick changing mechanism is used for changing the driving cell on the passenger vehicle. In the embodiment disclosed by the invention, the quick changing mechanism uses the vehicle body plate as an aligning device when the driving cell is changed, and besides, the vehicle body plate can be used as an application point for pushing the driving cell to enter a locking position, so that the phenomenon that the passenger vehicles move caused by directly pushing the driving cell is avoided. Besides, the cell plate and the vehicle body plate can form a relative movement effect, so that the difficulty of changing the driving cell is reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a battery positioning device for a new energy vehicle capable of rapidly replacing batteries. Background technique [0002] The driving batteries of current new energy passenger vehicles generally have two types: replaceable structure and non-replaceable structure. For the replaceable structure, it can not only be charged directly on the passenger car, but also can be replaced by replacing the fully charged driving battery, which is more flexible and convenient in use. [0003] Passenger cars with this type of structure usually use a quick-change mechanism to replace the driving battery. Currently, the driving battery is generally installed on the passenger car using a snap-fit ​​structure. This process generally includes lifting-translation- Lock the three processes. When the quick-change mechanism is installed, its force fully acts on the drive battery. Therefore, in the tra...

[0003] Passenger cars with this type of structure usually use a quick-change mechanism to replace the driving battery. Currently, the driving battery is generally installed on the passenger car using a snap-fit ​​structure. This process generally includes lifting-translation- Lock the three processes. When the quick-change mechanism is installed, its force fully acts on the drive battery. Therefore, in the translation process, its force directly acts on the passenger car, which causes the passenger car to move. This phenomenon occurs in Especially noticeable on some small cars
