[0002] As electric vehicle charging currents increase, the specifications of high-voltage wiring harnesses are also increasing. To ensure lightweight design, more and more electric vehicles are using aluminum busbars with excellent conductivity and low density as their high-voltage wiring harnesses. During use, the aluminum busbars need to be installed and fixed to the vehicle body or chassis. Currently, the installation of aluminum busbars is similar to that of traditional copper conductor high-voltage wiring harnesses. First, the aluminum busbars are fixed to the wire clamps, and then the wire clamps are fixed to the vehicle body or chassis with screws. However, due to the relatively poor ductility of aluminum busbars and their resistance to bending, if there are misaligned holes, the existing aluminum busbar installation method is difficult to align the holes during manual installation, seriously affecting production time. At the same time, after the wire clamps are installed, the deformation stress is concentrated in a certain area and cannot be relieved, which has a certain impact on the service life of the wire clamps or vehicle body mounting points.

[0003] Therefore, there is an urgent need to provide a new aluminum bar fixing device, which is expected to facilitate the installation and connection of the aluminum bar with the vehicle body or chassis, improve assembly efficiency, and at the same time help ensure that the fixing device has a good service life.

Since the fixing seat 1 can slide with a single degree of freedom relative to the mounting seat, it can absorb a certain manufacturing tolerance and is easier to align with the mounting position on the vehicle body or chassis, which is beneficial to improving the assembly efficiency of the aluminum bar 3; at the same time, after the fixing seat 1 is fixedly installed on the vehicle body or chassis, the installation deformation stress after installation can be released to a certain extent at the sliding connection position, which is beneficial to ensure that the fixing device has a good service life, and is also beneficial to improving the durability of the vehicle body mounting point.

[0025] In this embodiment, the aluminum bar mounting position 2a includes a mounting hole 201 formed on the mounting seat 2 and conforming to the aluminum bar 3 to be installed for the aluminum bar 3 to pass through; specifically, the mounting hole 201 here is a rectangular hole. During use, the aluminum bar 3 is passed through the mounting hole 201, generally with a small interference fit. Before the whole vehicle is assembled, the mounting seat 2 is first assembled at the set position of the aluminum bar 3; this structural design is simple in structure, reliable in positioning, good in structural strength, and is also conducive to further reducing assembly.

[0026] In this embodiment, there are two mounting holes 201 arranged side by side in an upper and lower direction, where "side by side" means arranged in parallel. The design of two mounting holes 201 arranged side by side in an upper and lower direction has a compact structure, and the positive and negative aluminum bars can be installed on the mounting base 2 at the same time, which is beneficial to improving the compactness of the aluminum bar arrangement of the entire vehicle.
