Abstract

The utility model discloses an automobile primary power supply controller including a fixed pedestal, a box cover which covers the fixed pedestal in a sealing manner and various electrical apparatus elements which are disposed inside the fixed pedestal, wherein the fixed pedestal and the box cover are prepared form plastic in a manner of injection moulding. Because the automobile primary power supply controller allows the various electrical apparatus elements to be disposed in a sealed box body and the fixed pedestal and the box cover employ an overall-plastic and dustproof design in a manner of die moulding, total weight of an integral controller is greatly reduced. In addition, the automobile primary power supply controller has a sealing dustproof effect so that internal electrical apparatus elements are free from being damaged due to an untight sealing.

Description

Automotive Main Power Controller

technical field

The utility model relates to automobile electrical spare parts, in particular to an automobile main power supply controller. the

Background technique

At present, most of the rear power controllers of city buses and tourist buses are assembled on-site from spare parts or concentrated in iron boxes. Parts assembly insurance adopts the fusible link method, and the fusible link is very ineffective as an insurance, and there is no protection for the second start, and this kind of electrical device is placed in the battery compartment without protection, and the electronic components will be electrolyzed after a long time Corrosion of the liquid, resulting in component aging, circuit failure, difficulty in starting, etc. For the controllers concentrated in the iron box, although the components are protected, the iron box is too heavy, it is inconvenient to install, and the iron box is not tightly sealed, and the electronic components will rot due to the corrosion of the electrolyte for a long time. the

A main power supply controller for an automobile, characterized in that it includes a fixing seat, a box cover sealed on the fixing seat, and various electrical components arranged inside the fixing seat, and the fixing seat and the box cover are both formed by plastic injection molding; The top surface of the surrounding walls of the fixed seat is provided with a ring groove, and a sealing ring is arranged in the ring groove; a locking buckle structure is arranged between the fixed seat and the box cover to fasten the box cover on the fixed seat; The thickness of the sealing ring is higher than the depth of the ring groove. the

The side wall of the fixing seat is provided with a buckle block, and the lid is provided with a bendable lock, and the lock buckle is bent downwards and folded on the buckle block to realize the fastening of the box cover and the fixing seat. the

The box cover is made of transparent material. the

After adopting the above scheme, the utility model has the following beneficial effects:

1. In the utility model, all electrical components of the main power supply controller of the automobile are arranged in a sealed box body, and the fixing seat and the box cover of the box body are all plastic dust-proof design formed by moulding, so the total weight of the whole controller is large In order to reduce the size, it also has the effect of sealing and dustproof, avoiding damage to internal electrical components caused by poor sealing;

2. Since the fixing seat and box cover of the main power controller of the car are made of plastic, it can prevent the cable burning phenomenon caused by the short circuit of the original metal shell power switch due to the failure of the contact shell;

3. The box cover of the automobile main power supply controller of the utility model can be made of transparent material, so that the whole box cover forms an observation window, which is convenient for observing the working conditions of the internal electrical components.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail. the

What the utility model discloses is a kind of automobile main power controller, as shown in Fig. 1 to Fig. 4, is the preferred embodiment of the utility model. The main power supply controller of the automobile comprises a fixed base 1, a box cover 2 sealed on the fixed base 1 and various electrical components 3 arranged inside the fixed base 1, wherein: the fixed base 1 and the box cover 2 are all made of plastic using mold injection molding. the

In order to realize the sealing between the fixed seat 1 and the lid 2, an annular groove 11 can be set on the top surface of the surrounding walls of the fixed seat 1, and then a sealing ring 4 is set in the annular groove 11, and then the fixed seat 1 and the The locking buckle structure provided between the box covers 2 fastens the box covers 2 on the fixing seat 1 . the

The locking buckle structure can be that a buckle block 12 is provided on the side wall of the fixed seat 1, and a bendable lock buckle 21 is arranged on the box cover 2, and the lock buckle 21 is bent downward and folded on the buckle On the block 12, the fastening of the box cover 2 and the fixing seat 1 can be realized. When the locking buckle 21 is bent outward, the buckled state of the locking buckle 21 and the buckle block 12 can be released, thereby opening the box cover 2 . the

The thickness of the sealing ring 4 can be higher than the depth of the ring groove 11, so that the lid 2 can contact the sealing ring 4 when fastened, so that the seal is tighter. However, the sealing ring 4 may be exposed outside, which affects the service life of the sealing ring. Therefore, the thickness of the sealing ring 4 can be made lower than the depth of the ring groove 11 , so that the sealing ring 4 is entirely located inside the ring groove 11 . At this time, a ring of convex edges 22 can be provided on the lower bottom surface of the box cover 2 opposite to the ring groove 11 of the fixing seat 1 . When the box cover 2 is covered on the fixed seat 1, the convex edge 22 extends into the ring groove 11 inside of the fixed seat 1 and contacts the seal ring 4, thereby making the seal tighter and preventing the seal ring 4 from being exposed. the

In addition, the box cover 2 can be made of transparent material to form an observation window to facilitate observation of the working conditions of the electrical components inside the fixing seat 1 . the

The above are only preferred embodiments of the present utility model, and are not intended to limit the technical scope of the present utility model. Therefore, any changes or modifications made according to the claims of the utility model and the specification should belong to the utility model. Within the scope covered by the utility model patent. the
