Description
Technical Field
The utility model relates to a shell structure, especially a vehicle control device's shell structure.
Background
The vehicle-mounted control device is an electronic control device for controlling the action of an actuating mechanism in a vehicle, generally circuit components are arranged in a casing, but the circuit components arranged in the casing in the vehicle-mounted control device can generate heat when working, especially when the vehicle-mounted control device needs to work in a high-temperature environment, the heat is more serious, and the working condition and the service life of the circuit components can be affected, but the traditional casing structure is difficult to ensure the requirement of the control device on heat dissipation performance.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple structure's vehicle mounted control device's shell structure has solved the problem that is difficult to guarantee the requirement of controlling means to the heat dispersion that exists among the prior art.
The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: including casing and apron, the apron setting is in the casing top and can dismantle with the casing and be connected, the inside holding chamber that is provided with the installation circuit board of casing, one side of casing is equipped with two and can stretches out the through opening of the waterproof electric connector socket of connecting on the circuit board, the surface interval distribution of the bottom of casing has a plurality of unequal fin of height, be provided with an at least bellying on the medial surface of apron, the upper surface in close contact with of the host system on the circuit board of bellying and installation in the casing for dispel the heat to host system.
Preferably, the inner surface of the bottom of the housing has a U-shaped base for fixedly mounting the circuit board and being in close contact with the surface of the power module provided on the circuit board for dissipating heat from the power module.
Preferably, the shell and the cover plate are made of materials which are easy to dissipate heat.
The utility model adopts the above structure, following advantage has: wholly through set up the unequal fin of a plurality of heights on casing surface, increase heat radiating area, the unequal design of height is convenient for ventilate to set up the boss and carry out the heat dissipation of contacting with the host system of circuit board on the apron through being connected with the casing, thereby utilize the heat radiation characteristic of casing and apron, improve vehicle-mounted control device's radiating effect, improved vehicle-mounted control device high reliability, high security and high adaptability under adverse circumstances.

Detailed Description
In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.
As shown in fig. 1, the whole body comprises a shell 2 and a cover plate 1, the cover plate 1 is arranged above the shell 2 and detachably connected with the shell, as shown in fig. 2 and 3, a containing cavity for installing a circuit board is arranged in the shell 2, one side of the shell 2 is provided with two through openings 4 capable of extending out of a waterproof electric connector socket connected on the circuit board, a plurality of radiating fins 5 with different heights are distributed on the outer surface of the bottom of the shell 2 at intervals, as shown in fig. 4, at least one protruding part 6 is arranged on the inner side surface of the cover plate 1, the protruding part 6 is in close contact with the upper surface of a main control module arranged on the circuit board in the shell 2 and used for radiating the main control module, the inner surface of the bottom of the shell 2 is provided with a U-shaped base 3, the U-shaped base 3 is used for fixedly installing the circuit board and is in close contact with the, the shell 2 and the cover plate 1 are made of materials which are easy to dissipate heat.
During the use, the circuit board is installed in the holding intracavity of casing 2, the bellying 6 on the apron 1 and the upper surface in close contact with of the host system on the circuit board, be used for dispelling the heat to host system, the U-shaped base 3 of the bottom of casing 2 and the surface in close contact with of the power module who sets up on the circuit board, be used for dispelling the heat to power module, the unequal fin 5 of a plurality of heights of the bottom of casing 2, increase heat radiating area, dispel the heat for the circuit board of casing 2 inside on the whole, the waterproof electric connector socket of connecting on the circuit board and external cable connection are stretched out to the through opening 4 department of casing 2.
Among them, the above-mentioned materials which are easy to dissipate heat are the prior art.
The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
