New energy vehicles typically have their battery packs fixedly attached to the load carrying structure of the vehicle body by supporting side rails. The support side beams are generally fixedly connected with the vehicle body through bolt assemblies, the bolt assemblies comprise a pair of mutually matched bolts and nuts, the positions of the bolt assemblies are generally called as mounting points, and the locking and fixing mode is called as mounting point support, so that the battery pack is kept stable in the running process of the whole vehicle.

When the vehicle is locked and fastened, the bolt passes through the supporting side beam and the bearing structure and then is in threaded connection with the nut, the tightening torque of the bolt is converted into positive pressure acting on the bearing structure and the supporting side beam along the axial direction of the bolt, and the positive pressure forms friction force on the vehicle body and the supporting side beam and is used for overcoming inertial force load of the supporting side beam caused by working conditions such as vibration, impact and the like in the running process of the whole vehicle. The calculation formula of positive pressure and friction force is as follows: f=μ×fn, where FN is positive pressure, μ is a friction coefficient, so in the precondition that the supporting side beam and the supporting structure are made of certain materials (i.e., μ is a constant), in order to ensure stability of the battery pack during the running process of the whole vehicle, the bolts need to form a sufficiently large positive pressure on the supporting structure and the supporting side beam, and typically, the positive pressure has a value of several tens kilonewtons to hundreds kilonewtons.

The support side sill generally includes an upper beam panel and a lower beam panel spaced above the lower beam panel for fixedly coupling the support side sill to the vehicle body. In the normal case, when in fixed connection, the upper beam plate is abutted against the lower side of the bearing structure, and the head of the whole vehicle bolt or the whole vehicle fixing nut is abutted against the lower beam plate; because the upper beam plate and the lower beam plate are both plate-shaped structures, the thicknesses of the upper beam plate and the lower beam plate are generally 1-2mm, the materials of the upper beam plate and the lower beam plate are generally aluminum materials, and the texture of the upper beam plate and the lower beam plate is softer, the lower beam plate is very easy to generate abnormal deformation due to excessive compression under the abutting of the head of a bolt, the whole car bolt is invalid, and the mounting stability of a battery pack is further affected.
