Technical Field
[0001] This utility model relates to the field of casing technology, and in particular to a casing with good positioning effect and easy assembly. Background Technology
[0002] In the field of modern electronic equipment and electromechanical systems, with the continuous increase in power density, heat dissipation has become a key factor restricting the improvement of equipment performance. The motor, located at the power supply end of the equipment, is one of the important considerations for its heat dissipation performance; the housing, as one of the main heat dissipation structures of the motor, cannot be ignored in terms of its heat dissipation effect; furthermore, existing housings are not effective in installing different end covers and motors, and cannot meet the needs of enterprises.
[0003] In view of the above, it is necessary to improve the existing casing structure to adapt to the current needs of casing use. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a housing with good positioning effect and easy assembly, including a housing, mounting ears symmetrically arranged on both sides of the housing, mounting holes on the mounting ears, bearing holes in the housing, mounting stops in the housing, fixing holes on the mounting ears, multiple positioning holes on the bottom of the housing, heat dissipation bosses on the bottom of the housing, and multiple positioning slot mechanisms arranged in a circumferential array on the housing. The positioning slot mechanisms are fixedly installed on the housing, and the mounting ears are fixedly installed on the housing.
[0005] As a further supplement to this technical solution, the mounting ear is also provided with a mounting inner hole for positioning the angle of the mounting end cap, and the mounting inner hole is located on the side of the mounting ear away from the mounting hole.
[0006] As a further supplement to this technical solution, the fixing hole is located on the central axis of the mounting ear.
[0007] As a further supplement to this technical solution, the bottom of the housing is also provided with multiple PIN slots for positioning the internal iron core PIN outlet device.
[0008] As a further supplement to this technical solution, heat dissipation putty is applied to the heat dissipation protrusion for heat dissipation.
[0009] As a further supplement to this technical solution, the positioning slot mechanism includes a first card block arranged symmetrically on the left and right sides, and a second card block disposed between the first card blocks on both sides, wherein the first card block and the second card block are fixedly installed on the housing.
[0010] As a further supplement to this technical solution, the cross-section of the second card block is a right-angled triangle.
[0011] As a further addition to this technical solution, the first and second card blocks are inclined inwards from below.
[0012] Its advantages include convenient and effective installation of the end cover, and the ECU protective cover can be installed well through the positioning slot mechanism. Applying heat dissipation paste to the heat dissipation protrusion can effectively help the ECU chip dissipate heat. Attached Figure Description

The positioning slot mechanisms 9 are fixedly installed on the housing 1, and the mounting ears 2 are fixedly installed on the housing 1. The mounting holes 3 are M4 threaded holes, and mounting screws are used to limit and fix the installed end caps. The fixing holes 6 are φ8.5cm in size and are used for positioning and fixing the assembly. The mounting stops 5 enable precise positioning of the assembled end caps. The bearing holes 4 facilitate subsequent assembly and fixing of the bearings. The positioning slot mechanisms 9 facilitate the subsequent installation of the ECU protective cover. The positioning holes 7 facilitate the limiting of the ECU after installation and the installation of self-tapping screws. The heat dissipation bosses 8 help dissipate heat after being combined with the ECU chip.
[0018] Among them, reinforcing blocks 12 are provided on both sides of the mounting ear 2, and the reinforcing blocks 12 are fixedly installed on the housing 1.
[0019] The mounting ear 2 is also provided with a mounting inner hole 10 for positioning the angle of the mounting end cap. The mounting inner hole 10 is located on the side of the mounting ear 2 away from the mounting hole 3 and is used to precisely position the angle of the mounting end cap. Its size is φ3.
[0020] Furthermore, the fixing hole 6 is located on the central axis of the mounting ear 2.
[0021] The bottom of the housing 1 is also provided with multiple PIN slots 11 for positioning the internal iron core PIN output device.
[0022] The heat dissipation protrusion 8 is coated with heat dissipation putty for heat dissipation, which helps the ECU chip dissipate heat after it is combined with the heat dissipation material.
