Description

Technical Field

[0001] This utility model relates to the field of electrical control box technology, and in particular to a metal cover for an automotive electrical control box. Background Technology

[0002] The core technologies of new energy vehicles are the drive motor, power battery, and electronic control system. New energy vehicles do not have a gearbox; they primarily rely on the electronic control system to achieve functions such as acceleration and hill climbing. Therefore, the electronic control system acts as the "gearbox," and its performance directly determines the vehicle's top speed, hill climbing ability, acceleration, and other performance characteristics. To protect critical components such as sensors, control units, and actuators in the electronic control system from damage caused by external impacts or pressure, new energy vehicles are equipped with an electronic control box to protect the system. The electronic control box mainly consists of a housing and a top cover. The instrument panel is mounted on the top cover. Currently, for airtightness, the instrument panel and top cover are generally fixed with screws and washers, which is cumbersome and inconvenient to assemble. Utility Model Content

[0003] Therefore, it is necessary to provide a metal cover for automotive electronic control boxes to address the above-mentioned problems.

[0004] A metal cover for an automotive electronic control box includes a cover plate, a mounting base, and multiple screws. The cover plate covers a housing and has multiple through holes along its periphery to accommodate fasteners. The mounting base protrudes from one side of the cover plate and has a receiving cavity to accommodate a control board. An instrument is mounted on the mounting base. One end of each screw is riveted to the mounting base, and the other end extends toward the cover plate. One end of the screw passes through the control board. One end of the screw has a first threaded hole, and the other end has a second threaded hole. The first threaded hole and the second threaded hole are not connected to each other.

[0005] In one embodiment, the cover plate includes a base plate portion and a support portion protruding from the base plate portion, the through hole is provided around the periphery of the base plate portion, and the fixing seat protrudes from the support portion.

[0006] In one embodiment, the periphery of the base plate is bent.

[0007] In one embodiment, a groove is provided on one side of the base plate, and the groove is provided corresponding to the fixing seat.

[0008] In one embodiment, the cover plate further includes a boss portion that protrudes from the support portion and is used for spraying QR codes.

[0009] In one embodiment, multiple reinforcing ribs are also included, which protrude from the support portion.

[0010] In one embodiment, the cover plate, the fixing seat, and the reinforcing rib are all formed by stamping.

[0011] In one embodiment, the screw is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The metal cover of the automotive electronic control box of this utility model is riveted to the fixing base by one end of the screw.
