Technical Field
[0001] This application relates to the field of electric vehicle controller technology, and in particular to a cover structure for an electric vehicle controller and an electric vehicle controller. Background Technology
[0002] Existing electric vehicle controllers consist of terminal blocks and covers. However, gaps can easily form between the cover and the terminal block, affecting waterproofing. Furthermore, they require separate manufacturing processes, impacting efficiency and cost. The placement of wire connection openings is arbitrary, resulting in messy wiring and compromising overall safety. Utility Model Content

The multiple mounting seats are recessed downward from the upper surface of the cover. Each mounting seat includes a front side wall, a rear side wall, a left side wall, a right side wall, and a bottom wall. The bottom wall has a stepped hole for placing a mounting nut.
[0005] Furthermore, a limit switch is provided on the rear side wall to allow the power supply line to pass through.
[0006] Furthermore, a through hole is provided at the junction of the bottom wall and the right side wall, and the through hole is rectangular.
[0007] Furthermore, a left clamping arm and a right clamping arm are provided below the through hole.
[0008] Furthermore, a front clamping arm and a rear clamping arm are provided below the through hole, along with a left clamping arm and a right clamping arm, forming a clamping space.
[0009] Furthermore, a left fixed wall and a right fixed wall are provided at the opening, and the left fixed wall and the right fixed wall extend upward along a line perpendicular to the surface of the cover.
[0010] Furthermore, the left and right fixed walls are triangular.
[0011] Furthermore, a support is provided between the left fixed wall and the right fixed wall.
[0012] Furthermore, the support portion includes a first arc and a second arc.
[0013] Furthermore, the mounting base extends downwards and is provided with a positioning part.
[0014] The electric vehicle controller includes the aforementioned cover structure and aluminum substrate, with the cover structure and aluminum substrate connected by screws.
[0015] The beneficial effects of this utility model are:
[0016] The top cover is a component of the controller's shape. At point 1, a nut can be pre-embedded during injection molding, or a square slot can be left in the injection molding process to hold the nut. Points 2, 3, and 4 are square slots, each consisting of three parts. The second part is where a high-current conductive busbar passes through the square slot. The third part is where the high-current conductive busbar, after passing through, forms a waterproof adhesive groove with the top cover. The fourth part is the space for the embedded cover plate (as shown in the diagram below). Point 5, along with the following five supporting structures, forms the overall support structure for the main circuit board, support pads, conductive sheets, MOS tube board, and aluminum base.
