Connection assembly Technical Field The present invention relates generally to the field of connection technology, and more particularly to a connection assembly for achieving a floating connection. Background The subframe of a vehicle typically serves to connect the body and the suspension system. Currently, some vehicle sub-frames are rigidly connected to the vehicle chassis fender by bolts. When the vehicle is traveling on a rough road, the front and rear suspensions may move and vibrate. These movements and vibrations are transmitted to the chassis fender through the rigid connection between the subframe and the chassis fender, causing the chassis fender to bear large dynamic loads and to be prone to fatigue failure. This is particularly disadvantageous for chassis shields made of, for example, plastic.
