In this embodiment, the fixing member 40 is provided with a connecting hole for mounting to the battery pack case. The fixing member 40 is detachably coupled to the battery pack case through the coupling hole.

The fixed bolster 100 that this embodiment provided, for single part, can the fixed pipeline 1 of centre gripping simultaneously, pencil 2 and electrically conductive row 3, compare each current functional structure (pipeline 1, pencil 2 and electrically conductive row 3) and set up corresponding fixed knot structure's design alone, can effectively reduce part quantity to in installation and dismantlement. In addition, the elastic pipe clamp 10, the elastic wire clamp 20 and the elastic plate clamp 30 are all split ring structures, and are used for detachably and elastically clamping corresponding functional structures (the pipeline 1, the wire harness 2 and the conductive bar 3), so that the assembly and disassembly are convenient. Specifically, the elastic tube clamp 10 has elasticity and an opening size smaller than the diameter of the pipe 1. During assembly, the pipe 1 is placed into the elastic tube clamp 10 through the opening of the elastic tube clamp 10, during which the elastic tube clamp 10 is elastically deformed to flare and elastically or partially returns to restrict the pipe 1 from leaving the elastic tube clamp 10 when the pipe 1 is placed into the elastic tube clamp 10.

When the wire harness 2 is placed on the elastic clip 20, the elastic clip 20 has an elastic force pressing the wire harness 2 inward. When the conductive bar 3 is placed in the elastic plate clip 30, the elastic plate clip 30 has an elastic force of pressing the conductive bar 3 inward. This arrangement allows the resilient clamp 10 to limit the axial movement of the pipe 1 and thus limit the relative movement of the pipe 1 and the resilient clamp 10.
