Problems solved by technology
During the operation of the whole vehicle, due to the bumping or twisting of the body, the connection point between the battery pack connection mechanism and the body connection mechanism will be pulled, which will easily cause damage to the connection point
In addition, the steel ball clamping battery pack connection mechanism and the vehicle body connection mechanism adopt a point connection method, the stress is too concentrated on one point, and the durability is poor
There is a problem of sliding teeth and unlocking stuck in the way of connecting the battery pack connection mechanism and the body connection mechanism by bolts

The embodiment of the invention discloses a battery pack and vehicle body connecting mechanism and a vehicle. The battery pack and vehicle body connecting mechanism comprises a shell, at least one clamping piece and a driving structure, a first containing cavity and a second containing cavity are formed in the shell, a through hole is formed between the first containing cavity and the second containing cavity, and a clamping opening is formed in the shell and communicates with the second containing cavity; the clamping piece is arranged in the second containing cavity and at least partially shields the through hole; the driving structure is arranged in the first containing cavity and comprises a first supporting base, an ejector rod and a driving assembly, the ejector rod is connected withthe first supporting base, and the driving assembly can drive the first supporting base to move up and down relative to the first containing cavity so as to drive the ejector rod to penetrate throughthe through hole to enter the second containing cavity to extrude the clamping piece, so that at least part of the clamping piece extends out of the clamping opening; or the first containing cavity is withdrawn to release the extrusion on the clamping piece, so that the clamping piece is contained in the second containing cavity. According to the invention, the contact area of the joint can be increased, and the durability can be improved.
Description
technical field [0001] The invention relates to the technical field of battery pack connection, in particular to a connection mechanism between a battery pack and a vehicle body and a vehicle. Background technique [0002] At present, there are mainly two ways to connect the battery pack and the body. One is to use bolts to push away the steel balls, so that the steel balls are stuck between the battery pack connection mechanism and the body connection mechanism to realize the connection. The other is to use bolts directly. Make a rigid connection. During the operation of the whole vehicle, due to the bumping or twisting of the body, the connection point between the battery pack connection mechanism and the body connection mechanism will be pulled, which will easily cause damage to the connection point. Moreover, the steel ball clamping battery pack connection mechanism and the vehicle body connection mechanism adopt a point connection method, the stress is too concentrated...
