Technical Field

[0001] The present application relates to the technical field of fuse boxes, and more specifically to a low-pressure waterproof fuse box for an automobile. Background Art

[0002] There are many electrical components installed in the car cockpit. Among them, the fuse box is responsible for transmitting driving information to various parts of the car body. It is a key component in automotive electronic control electrical components and one of the parts with high technical content and strict process requirements in the car body.

[0003] At present, a Chinese patent with announcement number CN211350555U discloses a new type of automobile fuse box, including a box body, a mounting plate is provided in the box body, a relay mounting part, a fuse mounting part and a spare fuse mounting part are provided on the mounting plate, and the spare fuse mounting part is located between the relay mounting part and the fuse mounting part; the relay mounting part is arranged with a plurality of relays, the fuse mounting part is arranged with a plurality of fuse sockets, and the spare fuse mounting part is arranged with a plurality of spare fuse sockets.

[0004] In the prior art, a fuse box similar to the above-mentioned one includes a lower shell and an upper cover, and no waterproof structure is provided between the lower shell and the upper cover. As a result, when the fuse box comes into contact with water, water stains can easily enter the interior of the box body through the gap between the lower shell and the upper cover, which can easily cause the fuse or relay to burn out. Therefore, there is room for improvement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a low-pressure waterproof fuse box for an automobile, which has the advantage of avoiding the fuse box from burning out and prolonging the service life of the fuse box.

[0017] By adopting the above technical solution and setting the embedding groove, the contact area between the relay mounting portion and the bottom of the relay protection shell can be increased, the sealing effect is increased, and the waterproof effect is further improved.

[0018] In a preferred embodiment: the second fixing mechanism includes a clamping ring fixed to the fuse mounting portion, and clamping blocks are provided on both sides of the fuse protection shell, and the clamping blocks are matched with the clamping ring.

[0019] By adopting the above technical solution, when the fuse protection shell is covered on the fuse installation part, the clamping block can be embedded in the clamping ring, thereby fixing the fuse protection shell and the fuse installation part, thereby improving the firmness of the installation of the fuse protection shell and improving the waterproof effect.

[0020] In a preferred embodiment: an elastic section is provided in the middle portion of the clamping block, and the elastic section has resilience.

[0021] By adopting the above technical solution and setting the elastic section, the card block can be easily deformed when pressed, thereby improving the convenience of the card block entering the clamping ring.

[0022] Compared with the prior art, this application has the following beneficial effects:

[0023] 1. When in use, use the mounting base to fix the fuse box in the center console of the car. When the surface of the fuse box is exposed to water, the relay waterproof strip and the fuse waterproof strip can both play a good waterproof effect, preventing water stains from entering the relay installation part and the fuse installation part through the gap, avoiding the fuse box from burning out, and prolonging the service life of the fuse box;

[0024] 2. When the relay protection shell is covered on the top of the relay installation part, the limit block will squeeze the limit plug plate to deform it. When the limit plug plate is deformed to a certain extent, the limit block can enter the limit hole, and then the relay protection shell can be firmly fixed on the relay installation part, which increases the firmness of the connection between the relay protection shell and the relay installation part and improves the waterproof effect of the relay installation part;

[0025] 3. When the fuse protection shell is covered on the fuse installation part, the clamping block can be embedded in the clamping ring, thereby fixing the fuse protection shell and the fuse installation part, thereby improving the firmness of the installation of the fuse protection shell and improving the waterproof effect of the fuse installation part.
