Technical Field

[0001] This utility model relates to the field of vehicle electrical box technology, and in particular to a highly wear-resistant vehicle aluminum shell that facilitates heat dissipation. Background Technology

[0002] The vehicle electrical box is an important component of the automotive electrical system. It primarily functions as an electrical circuit protection device, and is centrally installed in one or more specific locations within the vehicle, acting as a hub for the circuitry.

[0003] Because vehicles inevitably encounter bumps during operation, the internal electrical boxes rub against other components, which can lead to cracking after prolonged use, exposing and damaging the internal electrical parts. Furthermore, existing vehicle electrical boxes suffer from poor heat dissipation, making the internal components susceptible to burnout due to prolonged exposure to high temperatures. Therefore, improvements are necessary. Utility Model Content

The interior of the heat-spreading part is filled with deionized water, and the outer side of the pure copper sealing plate is tightly connected to the heat-conducting structure.

[0007] In a further technical solution, a liquid injection hole is opened on each side of the top cover. These two liquid injection holes are connected to the corresponding cell. A plug is provided on the outside of the liquid injection hole and the plug is welded to the liquid injection hole.

[0008] In a further technical solution, the heat dissipation fin structure is provided in two sets, which are symmetrically arranged on both sides of the top cover.

[0009] In a further technical solution, a sealing ring is sandwiched between the mating surfaces of the top cover and the bottom shell, and the sealing ring is sleeved on the outside of the limiting stop; the specifications of the surrounding shape of the limiting stop match the upper opening of the electrical assembly cavity, and the limiting stop and the upper opening of the electrical assembly cavity are engaged.

[0010] In a further technical solution, the inner side of the electrical assembly cavity is formed with multiple reinforcing ribs, the top ends of each reinforcing rib are respectively flush and distributed at intervals on the inner side of the electrical assembly cavity, and the limiting stop edge is limited and matched with the top ends of each reinforcing rib.

[0011] In a further technical solution, the top edge of the bottom shell is formed with multiple first connecting parts; the top cover is formed with multiple second connecting parts at its relative position, and the second connecting parts and the first connecting parts are fastened together by screws.

[0012] In a further technical solution, the side of the bottom shell is formed with at least two symmetrically arranged feet.

[0013] In a further technical solution, the wiring port is provided with a wiring kit, one side of which is formed with a screw part. The screw part is threaded with an outer nut and an inner nut. The screw part is inserted into the wiring port, and the outer nut and the inner nut are respectively clamped to the inner and outer sides of the wiring port.

[0014] In a further technical solution, a sealing ring is also fitted onto the screw section, and the sealing ring is clamped between the outer nut and the outer side of the bottom shell.
