Description

Technical Field

[0001] The utility model relates to the technical field of busbar fixing frames, in particular to a copper busbar fixing frame for new energy vehicles. Background Art

[0002] In hybrid vehicles, there is a device called an "inspiration motor", which can consume the power of the power battery to output torque when assistance is needed, and can also generate electricity to charge the power battery when there is surplus power.

[0003] Among them, the Touareg and Porsche P2 architecture V141 inspired motors are three-phase brushless motors, whose stators are composed of 36 coils, 12 per phase, arranged in a circle on the stator core. The lead wires of these coils are connected to one of the three busbars in the order of U / V / W three phases, and these busbars are bent into arcs in a fixed order with the outer diameter of the circle of coil arrangement, and are put together in the order of inside, middle, and outside, and installed on the stator core. Due to space limitations, the spacing between these three copper bars can only be about 1mm, which makes it difficult to simultaneously realize the positioning, installation, fixing, and insulation functions of the three-phase busbar.

[0004] The existing installation method is to design a plastic ring with three grooves on it for embedding three busbars. However, this ring has some shortcomings in design and materials, such as unreasonable positioning, easy leakage during use, and easy brittle cracking of materials due to long-term high temperature.
