Description

Technical Field

[0001] The present application relates to the field of electric vehicle controllers, and in particular to an electric vehicle controller with high structural strength. Background Art

[0002] The electric vehicle controller, as the main control component of the electric vehicle, generates a lot of heat during operation. In order to avoid the internal temperature of the electric vehicle controller being too high and causing damage to its components, the relevant industry often fixes its power tubes on the radiator to achieve heat dissipation. Traditionally, the power tube is directly fixed to the radiator with screws, or the spring is fixed to the radiator and then the power tube is pressed on the radiator through the spring. This part of the structure usually requires machining. However, traditional machining is more likely to produce machining errors during the machining process, and the machining cost is relatively high. Utility Model Content

[0003] In order to improve the above problems, the present application provides an electric vehicle controller with high structural strength.

[0004] The electric vehicle controller provided in this application has a high structural strength and adopts the following technical solution:

[0005] An electric vehicle controller with high structural strength comprises a die-cast shell and a plastic cover plate, wherein the die-cast shell and the plastic cover plate are formed at one time by a mold, the die-cast shell and the plastic cover plate cooperate with each other, and a reinforcing rib is provided on the side of the plastic cover plate facing the die-cast shell.

[0006] By adopting the above technical scheme, since the die-cast shell and the plastic cover are both formed at one time by the mold, the error occurring during the processing of the die-cast shell and the plastic cover is reduced, which is also beneficial to cost saving; the reinforcing ribs can reduce the possibility of deformation of the plastic cover, improve the structural strength of the plastic cover, further reduce the processing cost of the plastic cover, and improve the stability of the die-cast shell and the plastic cover after connection; when the die-cast shell and the plastic cover are matched, compared with the traditional matching structure, this scheme can reduce the possibility of glue leakage.

[0007] Preferably, a boss is provided on one side of the inner wall of the die-cast shell.

[0008] By adopting the above technical solution, the boss can limit the installation position of the spring piece, making it easier for the spring piece to be installed in the die-cast housing.

[0009] Preferably, a clearance groove is provided on the reinforcing rib, and the clearance groove is for the boss to be embedded.

[0010] By adopting the above technical solution, when the die-cast shell and the plastic cover are matched, the boss is embedded in the give way groove, which is convenient for the die-cast shell and the plastic cover to fit together. The boss also positions the plastic cover, which is convenient for the connection between the die-cast shell and the plastic cover.

[0011] Preferably, a first square push rod is fixedly connected to the reinforcing rib.

[0012] By adopting the above technical solution and setting the first side push rod, the possibility of the plastic cover plate and the reinforcing ribs sticking to the mold is reduced, which facilitates demoulding.

[0013] Preferably, a first bolt hole is formed on the plastic cover plate, and a second bolt hole is formed on the die-cast housing, and both the first bolt hole and the second bolt hole are for bolts to be screwed into.

[0014] By adopting the above technical solution, when the die-cast shell and the plastic cover need to be connected, the die-cast shell and the plastic cover are fitted together, and then the bolts are moved to screw into the first bolt hole and the second bolt hole. The bolts can limit the die-cast shell and the plastic cover, thereby realizing the connection between the die-cast shell and the plastic cover.

[0015] Preferably, an embedding groove is provided at the opening of the first bolt hole for the bolt to be embedded in, a positioning block is provided on the side of the plastic cover plate facing the die-cast shell, and a positioning groove is provided at the opening of the second bolt hole for the positioning block to be embedded in.

[0016] By adopting the above technical solution, when the bolt is screwed into the first bolt hole, the bolt is embedded in the embedding groove and abuts against the bottom of the embedding groove. At this time, the bolt will not leak out, which is convenient for gluing. When the die-cast shell and the plastic cover need to be connected, the plastic cover is moved so that the plastic cover drives the movement of the positioning block, so that the positioning block is embedded in the positioning groove. The positioning groove can limit the positioning block, thereby limiting the position of the plastic cover, which is convenient for connecting the die-cast shell and the plastic cover.

[0017] Preferably, a limiting rib is fixedly connected to one side of the die-cast housing facing the plastic cover plate, and the plastic cover plate is fitted with the inner side of the limiting rib.

[0018] By adopting the above technical solution, when the die-cast shell and the plastic cover need to be connected, the plastic cover is moved so that the plastic cover fits the inner wall of the limiting rib. The limiting rib can limit the plastic cover, which facilitates the connection between the die-cast shell and the plastic cover.
