Abstract
The utility model discloses an electric automobile centralized control screen power amplifier chip fixed structure, power amplifier chip is connected through the wire with the separation of circuit board, power amplifier chip fixes through the apron and the centralized control is shielded on the interior tank wall of mainframe box. The utility model discloses a technical scheme, direct with the tank wall contact and through the tank wall heat dissipation with power amplifier chip, can realize power amplifier chip's good heat dissipation.
Description
Technical field
The utility model relates to electric automobile, particularly relates to the collection control screen mainframe box of electric automobile.
Background technology
The power amplifier chips power consumption of electric automobile collection control screen is comparatively large, heat radiation difficulty.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of electric automobile collection control screen power amplifier chips fixed structure, ensures efficiently radiates heat.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: electric automobile collection control screen power amplifier chips fixed structure, power amplifier chips is separated with circuit board and is connected by wire, and described power amplifier chips is fixed on the internal box wall of collection control screen mainframe box by cover plate.
Preferably, described cover plate comprises rectangular body, and described rectangular body is provided with self-clinching nut and controls the internal box wall shielding mainframe box fix with collection, and the width two sides of described rectangular body and one of them side of length are provided with flange.
Preferably, described cover plate is Zinc-coated steel-plated punch molding structure.
The technical solution adopted in the utility model, power amplifier chips is separated with circuit board and is connected by wire, circuit board heating amount can be reduced like this, power amplifier chips is fixed on by cover plate on the internal box wall of collection control screen mainframe box simultaneously, such power amplifier chips is directly contacted with tank wall and is dispelled the heat by tank wall, can realize the good heat radiating of power amplifier chips.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is electric automobile collection control screen mainframe box vertical view;
Fig. 2 is schematic diagram on rear side of Fig. 1;
Fig. 3 is schematic diagram on front side of Fig. 1;
Fig. 4 is the structural representation of cover plate;
Fig. 5 is the side structure schematic diagram of cover plate;
Fig. 6 is the cross-sectional configuration schematic diagram of cover plate.
Embodiment
As shown in Figure 1 to Figure 3, electric automobile collection control screen mainframe box, the circuit board comprising casing 1 and be located in casing, described circuit board is connected with splicing ear, circuit board is integrated with various chip.Described casing 1 upper cover has case lid 2, and case lid 2 surrounding is provided with lower hem 21, and lower hem 21 is fixed by screw and casing 1.
Both sides, the front and back sidewall outer wall of casing 2 is provided with fixing ear 11, fixing ear 11 is all in L-type, fixing ear first side is provided with fixing hole and is screwed with casing, and the second side of fixing ear 11 is also provided with fixing hole, and this fixing hole can be fixed by screw and support.
In addition, the front side wall of described casing 2 is provided with louvre 13, is beneficial to heat radiation.The rear wall of described casing is provided with terminal outlet 12, and splicing ear is stretched out by terminal outlet.The inner bottom surface of described casing is provided with fixing lug boss at corner location, and described board support is in fixing lug boss and be screwed.The inner bottom surface corresponding circuits plate of described casing is provided with heat radiation boss.Chip or the larger position of other caloric values directly can be contacted with the boss that dispels the heat, ensure its radiating effect.And casing and case lid are aluminum punch forming structure, not only lighter weight, and good heat dissipation effect.
Described collection control screen mainframe box is provided with power amplifier chips, because power amplifier chips caloric value is comparatively large, is therefore separated with circuit board by described power amplifier chips and is connected by wire.Can reduce circuit board heating amount like this, be fixed on the internal box wall of collection control screen mainframe box by cover plate 3 by described power amplifier chips, such power amplifier chips is directly contacted with tank wall and is dispelled the heat by tank wall, can realize the good heat radiating of power amplifier chips simultaneously.
As shown in Figures 4 to 6, described cover plate 3 comprises rectangular body, described rectangular body is provided with self-clinching nut 32 and controls with collection the internal box wall shielding mainframe box and fix, and the width two sides of described rectangular body and one of them side of length are provided with flange 31, and power amplifier chips is positioned at the space that flange surrounds.Described cover plate 3 is Zinc-coated steel-plated punch molding structure.
