Embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of housing of car-mounted terminal, with reference to Fig. 1, including for fixing the panel 1 of display screen and being fixed on panel 1
On be used for the machine box 2 of electronic device is installed, the top surface of machine box 2 offers multiple heat emission holes 3, and the aperture of heat emission hole 3 is upward.
As shown in Fig. 2, being provided with storage tank 4 annular in shape on 3 inner wall of heat emission hole, cricoid bullet is connected with storage tank 4
Property part 5, the through hole internal diameter of the elastic component 5 are gradually reduced from top to bottom.The top and bottom of elastic component 5 are interior with storage tank 4
Wall is close to keep sealing, and rounded slide plate 6 is connected with perpendicular to its axial slip with to elasticity in the through hole of elastic component 5
The through hole of part 5 is sealed, and the diameter of slide plate 6 is more than the minimum diameter of through hole, so that heat emission hole 3 keeps sealing, ensures that it is anti-
Water-based energy.
In order to ensure the heat dissipation performance of heat emission hole 3, due to there is sky between the side wall of elastic component 5 and the inner wall of storage tank 4
Between, therefore, venthole 7 being opened up in the upper and lower ends of elastic component 5, venthole 7 connects the space between elastic component 5 and storage tank 4,
Heat dissipation channel is formed, the hot-air in machine box 2 can carry out heat exchange with outside air.
Due to partition venthole 7 formed heat dissipation channel, it is necessary to elastic component 5 occur moderate finite deformation with 4 inner wall of storage tank
Close to further improve water resistance, deflection needed for reduction elastic component 5, on side wall of the elastic component 5 towards storage tank 4
Position between 7 height of venthole sets cricoid Sealing shield ring 8.After housing soaks, current enter heat emission hole 3, push away
Dynamic slide plate 6 moves down, and slide plate 6 is hard, and compressing elastic component 5 deforms, and promotes Sealing shield ring 8 to be bonded with 4 inner wall of storage tank, so that
Heat dissipation channel is separated to play the role of waterproof.
To make Sealing shield ring 8 be bonded more preferably with 4 inner wall of storage tank, on the inner wall that storage tank 4 corresponds to 8 height of Sealing shield ring
Offer the cricoid groove 12 coordinated with Sealing shield ring 8.So as to promote the inner wall of the fitting storage tank 4 of Sealing shield ring 8 when slide plate 6
When, Sealing shield ring 8 is embedded in groove 12, and water resistance is more preferable.
4 top of storage tank and bottom are both provided with inclined-plane, and top inclined-plane is downwardly inclined, and bottom bevel tilts upward.So as to
The water of heat emission hole 3 is flowed into through 3 hole wall of heat emission hole will not enter the space between storage tank 4 and elastic component 5, even if there is water inflow,
Also can be stopped by the inclined-plane of 4 bottom of storage tank without entering inside machine box 2.
The space between storage tank 4 and elastic component 5 is flowed into along 3 inner wall of heat emission hole in order to further reduce water, in slide plate 6
Upper surface sets water suction flexible dielectric material 10, and pp cottons are used in the present embodiment.And it is located at the top of storage tank 4 in heat emission hole 3
Card slot 9 is set on inner wall, and limit water suction flexible dielectric material 10 using card slot 9 moves toward heat emission hole 3 close to extraneous aperture, prevents
Only it drops from heat emission hole 3.When only a small amount of water enters in heat emission hole 3, the water on hole wall can be absorbed by pp cottons.And work as
Into the water in heat emission hole 3 it is very big when, pp cottons are saturated with water, and weight increases and glides, promote below slide plate 6 slide so that
Sealing shield ring 8 is promoted to seal heat emission hole 3.
The top of heat emission hole 3 is provided with Air Filter 11.Drop so as to be reduced using Air Filter 11 into the ash in heat emission hole 3
Dirt, prevents its from blocking venthole 7 and influencing heat dissipation performance, and reduce accumulation of the dust on slide plate 6 and cause slide plate 6 move down by
Heat emission hole 3 is shut.
The operation principle of the present embodiment is：
Offer heat emission hole 3 on the machine box 2 of housing, heat emission hole 3 passes through the venthole 7 on elastic component 5 and in communication
Storage tank 4 and keep the connection inside and outside machine box 2 so that in machine box 2 electronic component produce heat can be shifted through heat emission hole 3
To the external world, to ensure the stabilization of the environment of electronic component operation.When vehicle interior is intake and along heat emission hole 3 toward 2 inside stream of machine box
Fashionable, water is absorbed by pp cottons first, and has a small amount of water to accumulate on the slide plate 6 of lower section.The water suction gravity increase of pp cottons and along card slot 9
To downslide, compressing slide plate 6 is moved axially along the through hole of elastic component 5, since 5 through hole internal diameter of elastic component gradually decreases from top to bottom,
And slide plate 6 is hard material, therefore, slide plate 6 is oppressed elastic component 5 and is deformed, and elastic component 5 oppresses Sealing shield ring 8 and 4 fovea superior of storage tank
Groove 12 is bonded, so that elastic component 5 seals heat emission hole 3, prevents water from entering inside machine box 2.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
