Background

The controller of electric motor car is the core of whole car, and the power tube during operation on the controller circuit board can give off more heat, and the controller temperature of electric motor car can constantly rise after long-time the use to influence the life of controller. In addition, the environment for using the electric vehicle is relatively severe, and the requirements on water resistance, fire resistance and the like are also high.

In the prior art, a plastic shell or a cast aluminum shell is often adopted as a shell of an electric vehicle controller. The plastic shell has the defects of no fire resistance, high cost, poor waterproof performance, low strength, heavy weight, low production efficiency, poor aesthetic property and the like. Although the heat dissipation performance of the cast aluminum shell is improved relative to that of the plastic shell, the whole heat dissipation part is die-cast on the shell, the whole temperature is still high through the heat dissipation of the whole shell, and the service life of components in the circuit board can be influenced. In addition, the cast aluminum housing has high cost, inconvenient processing, and still not ideal waterproof performance, corrosion resistance, service life and aesthetic property.

Disclosure of Invention

The utility model discloses aim at to the defect of current mould shell and cast aluminium shell controller, provide a radiating effect is good, and waterproof performance is good, and intensity is high, the installation of being convenient for, the appearance is pleasing to the eye, and is corrosion-resistant, low in production cost, waterproof, the effectual electric vehicle controller shell that takes precautions against earthquakes.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

electric vehicle controller shell, including casing and apron, its characterized in that: the shell and the cover plate are formed by stamping metal plates, part of the shell is in contact with a power tube of a controller PCB, and aluminum radiating fins are arranged outside the part of the shell in contact with the power tube. The shell is formed by stamping a metal plate, has attractive appearance and corrosion resistance, is processed by a stamping process, is convenient to produce, has low cost and greatly reduces the weight of the shell to be lower than that of a cast aluminum shell. Set up aluminium system radiating fin in the shell department that contacts with the power tube, can directly distribute away a large amount of heats that the power tube produced through radiating fin, other positions temperature of casing is lower, and is less to other components and parts temperature influences on the PCB board in the casing, prolongs its life.

It is further characterized in that: the radiating fins are embedded and installed on the shell. The radiating fins and the shell adopt a split structure, so that the radiating fins and the shell are convenient to produce, install and replace. The radiating fins can be made of aluminum profiles, so that the radiating fins are convenient to process and low in cost.

And further: the cover plate shell is connected in a convex point buckling mode, and the cover plate and the shell are sealed through dispensing. The cover plate and the shell are connected in a buckling mode, the installation is convenient, a plurality of convex point buckles are distributed on the periphery of the shell, the cover plate and the shell are buckled more closely and flatly, and the glue dispensing sealing between the cover plate and the shell is combined, so that a better waterproof effect is achieved.

Preferably, the following components: the edge of the cover plate is provided with a flanging, and a rib groove is formed in the middle of the cover plate. The structure of turn-ups and rib groove can increase the intensity of apron, prevents that the apron atress back distortion from guaranteeing the laminating degree with the shell, ensures the whole water-proof effects of controller.

It is further characterized in that: the middle of the shell is convex, and two sides of the shell are lower; the inner side of one side shell is contacted with the power tube. The middle bulge part of the shell is used for accommodating higher components such as electrolytic capacitors and the like and ensuring a certain heat dissipation space. One side of the lower two sides is used for arranging an input/output interface, and the lower height of the other side can be directly contacted with the power tube, so that the heat transfer efficiency is improved.

Preferably: the tops of the radiating fins are flush with the middle bulge of the shell. The arrangement of the radiating fins is flush with the bulges of the shell, so that the appearance of the controller forms a whole and is more attractive.

Preferably: the section of each radiating fin is comb-shaped, and the ratio of the fin spacing to the fin height is 1:5-1:8. the cross section of the radiating fin is comb-shaped, and the radiating space between the fins is linear, so that the air circulation is facilitated. Compare conventional radiating fin, the radiating fin wing interval in the utility model is bigger, the circulation of the air of also being more convenient for. The arrangement of the radiating fins further enhances the radiating effect.

Preferably, the following components: the shell and the cover plate are made of stainless steel or galvanized plates, so that the stamping processing is convenient, and the assembled controller is attractive in appearance and corrosion-resistant.

The utility model discloses a casing and the apron of metal sheet punching press combine together with the heat dissipation fin of aluminium alloy for electric vehicle controller shell has light in weight, and intensity is high, and the processing of being convenient for, equipment, the cost of manufacture is low, and the radiating effect is good, and the appearance is pleasing to the eye, and is corrosion-resistant, waterproof, shockproof advantage such as effectual. Adopt the utility model discloses electric vehicle controller of equipment, life is longer.

Detailed Description

As shown in fig. 1-3, an electric vehicle controller housing comprises a housing 1 and a cover plate 2, wherein the housing 1 and the cover plate 2 are formed by stamping galvanized plates or stainless steel plates. The stamped metal shell 1 and the stamped cover plate 2 are attractive in appearance, corrosion-resistant, convenient to produce, low in cost and greatly lower in weight than a cast aluminum shell. The cover plate 2 is connected with the shell 1 in a convex point buckling mode, and installation is more convenient. The cover plate 2 and the shell 1 are sealed through the glue dispensing 4, and a better waterproof effect is achieved. The edge of the cover plate 2 is provided with a flanging, and a rib groove is arranged at the middle position of the cover plate for increasing the strength of the cover plate 2 and preventing the cover plate 2 from being distorted and deformed after being stressed. The middle of the shell 1 is convex, and the two sides are lower. One side is used for arranging an input/output interface, and the inner side of the shell 1 on the other side is contacted with a power tube of a controller PCB. The outer part of the contact part of the shell 1 and the power tube is provided with an aluminum radiating fin 3. One side casing 1 contacts with the power tube, can directly distribute away a large amount of heats that the power tube produced through radiating fin 3, and other positions temperature of casing 1 is lower, and is less to other components and parts temperature influences on the PCB board in the casing 1, prolongs its life. The tops of the radiating fins 2 are flush with the middle bulge of the shell 1, so that the whole appearance is attractive. The section of the radiating fin 3 is comb-shaped, and the ratio of the fin spacing to the fin height is 1:5-1:8. the heat dissipation space among the fins is linear, so that the air circulation is facilitated; the larger fin spacing is also more conducive to air circulation. The structure of the heat dissipation fins 3 further enhances the heat dissipation effect.
