Detailed description of the invention
Further set forth advantage of the present invention below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1, is the stereogram of the decoration of automobile starting switch in a preferred embodiment. DecorateThe sidewall of part 1 is provided with discharge opening 12, and discharge opening 12 is vertical arrangement, and extend the lower end of self-chambering gadget 1To the middle part of decoration 1 sidewall, in this embodiment, preferably, the quantity of discharge opening 12 is 4,Can, in the situation that large water gaging enters vehicle switch, ensure certain displacement, can not cause decoration 1Filled up by water with the gap 4 between main casing 3, avoid excessive water to flow to switch inside. In this embodiment,12 of every two discharge openings form draw-in groove 11, corresponding this draw-in groove 11, the main casing 3 of automobile starting switchBeing provided with snap fit bar 32, with reference to Fig. 4, is the explosive view of a preferred embodiment automobile starting switch, main casing3 sidewall outside is provided with the snap fit bar 32 of horizontal stripe, makes the draw-in groove 11 of decoration 1 can fasten main casing 3Snap fit bar 32, decoration 1 is connected with main casing 3, and the junction of decoration 1 and main casing 3Only have discharge opening 12 these openings that arrange, other connecting portions are closely to connect. Correspondence arranges this cardGroove 11 and snap fit bar 32, make to be connected more firmly between main casing 3 and decoration 2, can be because of vapourRocking of car causes decoration to come off, thereby ensured the water resistance of switching device.
Please refer to Fig. 3, is the automobile starting switch birds-eye perspective of this preferred embodiment, main casing 3 sidesWall is provided with vertical rib 31, for decoration described in radial support. In this embodiment, vertically rib 31Quantity be 4, and symmetrical about the central shaft of main casing 3, so vertical rib 31Structure, can ensure decoration 1 inward flange radial support balance. In the present embodiment, described vertical rib 31And the contact gap 5 of described decoration 1 is between 0-0.1mm, and this contact gap 5 can ensure decoration 1Mutually support diametrically with main casing 3, and water is preferred, flows to switching device from water pouring mouth 12Outward.
Have after said structure, when decoration 1 is installed, first decoration 1 is inserted to insertion process downwardsIn, the draw-in groove 11 on decoration outwards overturns, and makes the snap fit bar 32 of main casing 3 be inserted into decorationOn draw-in groove 11 in, complete the installation of decoration 1.
Referring to Fig. 2, is the automobile starting switch cross-sectional view of a preferred embodiment, and this automobile starting is openedPass comprises button housing 2, is sheathed on the decoration 1 outside button housing 2 and is wrapped in decoration 1Main casing 3, wherein has the first gap 4, button between main casing 3 outward flanges and decoration 1 inward flangeBetween housing 2 outward flanges and described decoration 1 inward flange, there is the second gap 8, the lower end of button housing 2Be set in the upper end of main casing 3, make the overlapping at vertical direction of button housing 2 and main casing 3, therebyReach waterproof effect. Preferably, in the present embodiment, the part shape being connected between main casing 3 and decoration 1Become the bottom surface in the first gap 4, this bottom surface is inclined-plane, and meanwhile, discharge opening 12 is located at inclined-planeMinimum point; Button housing 2 surfaces are the arc of intermediate projections, and button housing 2 parts are exposed decoration 1Opening, the lower edge of button housing 2, lower than the upper edge of main casing 3, is shown thereby make to drop on button housing 2The water of face enters into by the second gap 8 between button housing 2 and decoration 1 along button housing 2In one gap 4.
Have after the structure of above-described embodiment, in the time that water is fallen on button housing 2, due to case housing 2Surface be intermediate projections, the structure that edge is recessed, the self gravitation of water in addition, falls button housingWater on 2 will flow to from button housing 2 middle parts button housing 2 edges, and from button housing 2 and decorationThe second gap 8 that part is 1 flows into automobile starting switch, enters the water in the second gap 8 due to self gravitation,Flow to the first gap 4 between decoration 1 and main casing 3. When flowing into, the water yield in this first gap 4 is lessTime, due to the tension force of liquid, water is by resting on the bottom surface in the first gap 4, due to discharge opening 12Be located at the lowest part in the first gap 4, along with the accumulation of moisture, water will from height to low flow, underOptional position, bottom surface flow to discharge opening 12, so water just flows out decoration 1 from discharge opening 12, and this vapourCar starting switch just has water-proof function. By the structure of this second gap 8, the first gap 4 and discharge opening 12Make, formed a drainage path of this vehicle switch, enter into the water of automobile starting switch inside inevitable throughBy according to being that described drainage path is discharged through the order of the first gap 4, the second gap 8, discharge opening 12Outside described automobile starting switch.
Because discharge opening 12 is located at the lowest part in the first gap 4, the water that makes to enter the first gap 4 canAccording to self gravitation natural flow, with respect to the design that drainage pipe or flat bottom or non-inclined-plane are set,Drainage is faster, and moisture can not rest on outside the sidewall of main casing 3, has ensured discharge rate.
In the preferred embodiment, as shown in Figure 2, button housing parts exposes the opening of described decoration,The downward push switch of person easy to use. Meanwhile, the lower edge of button housing 2 is lower than the upper edge of main casing 3,And button housing 2 moves up and down with respect to main casing 3 only, even if button housing 2 is positioned at highest point,Button housing 2 is still mutually overlapping in vertical direction with the coupling part of main casing 3, prevent moisture fromBetween this gap, flow into.
Meanwhile, automobile starting switch also comprises pcb board 7, is positioned at institute's main casing 3 inside, for prevent intoThe water that enters main casing 3 touches pcb board 7 and causes pcb board 7 short circuits, in the present embodiment, and pcb board 7Outer wrapping silica gel 6, makes pcb board 7 entirety be arranged in the internal cavity of silica gel 6.
Adopt after technique scheme, enter on described automobile starting switch surface or inner water by drainageTo gap, then discharge described starting switch by the discharge opening arranging, anti-sealing enters into start and opensInside the Pass pcb board on, avoid short circuit or damage, the security when affecting user and driving a vehicle.
It should be noted in the discussion above that embodiments of the invention have preferably implementation, and not the present invention is appointedThe restriction of what form, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement to becomeMore or be modified to the effective embodiment being equal to, do not depart from the content of technical solution of the present invention in every case, according to thisAny amendment or equivalent variations and modification that the technical spirit of invention is done above embodiment, all still belong toIn the scope of technical solution of the present invention.
