Embodiment
Advantage of the present invention is set forth further 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.The sidewall of decoration 1 is provided with discharge opening 12, discharge opening 12 is in vertically arrangement, the lower end of self-chambering gadget 1 extends to the middle part of decoration 1 sidewall, in this embodiment, preferably, the quantity of discharge opening 12 is 4, can when large water gaging enters vehicle switch, ensure certain displacement, the gap 4 between decoration 1 and main casing 3 can not be caused to be filled up by water, avoid excessive water to flow to switch internal.In this embodiment, draw-in groove 11 is formed between every two discharge openings 12, this draw-in groove 11 corresponding, the main casing 3 of automobile starting switch is provided with snap fit bar 32, with reference to Fig. 4, it is the explosive view of a preferred embodiment automobile starting switch, the sidewall outside of main casing 3 is provided with the snap fit bar 32 of horizontal stripe, make the draw-in groove 11 of decoration 1 can fasten the snap fit bar 32 of main casing 3, decoration 1 is connected with main casing 3, and decoration 1 only exists this opening of discharge opening 12 of setting with the junction of main casing 3, other connecting portions are compact siro spinning technology.Correspondence arranges this draw-in groove 11 and snap fit bar 32, makes to be connected more firm between main casing 3 with decoration 2, decoration will be caused to come off because of rocking of automobile, thus ensure that the water resistance of switching device.
Please refer to Fig. 3, be the automobile starting switch birds-eye perspective of this preferred embodiment, main casing 3 sidewall is provided with vertical rib 31, for decoration described in radial support.In this embodiment, the quantity of vertical rib 31 is 4, and symmetrical about the central shaft of main casing 3, the structure of so vertical rib 31, can ensure that decoration 1 inward flange radial support balances.In the present embodiment, the contact gap 5 of described vertical rib 31 and described decoration 1 is between 0-0.1mm, and this contact gap 5 can ensure that decoration 1 and main casing 3 support diametrically mutually, and water is preferred, flows to switching device from water pouring mouth 12.
After having said structure, when installing decoration 1, first inserted downwards by decoration 1, in insertion process, the draw-in groove 11 on decoration outwards overturns, and in the draw-in groove 11 that the snap fit bar 32 of main casing 3 is inserted on decoration, completes the installation of decoration 1.
Refer to Fig. 2, it is the automobile starting switch cross-sectional view of a preferred embodiment, the main casing 3 that this automobile starting switch comprises button housing 2, is sheathed on the decoration 1 outside button housing 2 and is wrapped in decoration 1, wherein between main casing 3 outward flange and decoration 1 inward flange, there is the first gap 4, there is between button housing 2 outward flange and described decoration 1 inward flange the second gap 8, the lower end of button housing 2 is set in the upper end of main casing 3, make the overlapping at vertical direction of button housing 2 and main casing 3, thus reach waterproof effect.Preferably, in the present embodiment, the part be connected between main casing 3 with decoration 1 defines the bottom surface in the first gap 4, and this bottom surface is inclined-plane, and meanwhile, discharge opening 12 is located at the minimum point on inclined-plane; Button housing 2 surface is the arc of intermediate projections, button housing 2 part exposes the opening of decoration 1, the lower edge of button housing 2 lower than the upper edge of main casing 3, thus makes the water dropping on button housing 2 surface enter into the first gap 4 by the second gap 8 between button housing 2 and decoration 1 along button housing 2.
After there is the structure of above-described embodiment, when water is fallen on button housing 2, surface due to case housing 2 is intermediate projections, the structure that edge is recessed, the self gravitation of water in addition, the water fallen on button housing 2 will flow to button housing 2 edge, and flow into automobile starting switch from the second gap 8 between button housing 2 and decoration 1 in the middle part of button housing 2, the water entering the second gap 8, due to self gravitation, flows to the first gap 4 between decoration 1 and main casing 3.When the water yield flowing into this first gap 4 is less, due to the tension force of liquid, water will rest on the bottom surface in the first gap 4, because discharge opening 12 is located at the lowest part in the first gap 4, along with the accumulation of moisture, water will from height to low flowing, namely discharge opening 12 is flow to from bottom surface optional position, so water just flows out decoration 1 from discharge opening 12, this automobile starting switch just has water-proof function.By the structure of this gap 4, the second gap 8, first and discharge opening 12, constitute a drainage path of this vehicle switch, enter into that the water of automobile starting switch inside is inevitable discharges outside described automobile starting switch via according to through the order of the first gap 8, gap 4, second, discharge opening 12 and described drainage path.
Because discharge opening 12 is located at the lowest part in the first gap 4, make the water entering the first gap 4 can according to self gravitation natural flow, relative to the design arranging drainage pipe or flat bottom or non-inclined-plane, drainage be faster, moisture can not rest on outside the sidewall of main casing 3, ensure that 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.Simultaneously, 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 relative 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, prevents moisture from flowing between this gap.
Meanwhile, automobile starting switch also comprises pcb board 7, is positioned at institute's main casing 3 inner, touch pcb board 7 for preventing the water entering main casing 3 and cause pcb board 7 short circuit, in the present embodiment, pcb board 7 outer wrapping silica gel 6, makes pcb board 7 entirety be arranged in the internal cavity of silica gel 6.
After adopting technique scheme, enter described automobile starting switch on the surface or the water of inside be drained in gap, discharge opening then by arranging discharges described starting switch, anti-sealing enters on the pcb board in starting switch, avoid short circuit or damage, affect fail safe when user drives a vehicle.
Should be noted that, embodiments of the invention have preferably implementation, and not any type of restriction is done to the present invention, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement change or be modified to equivalent effective embodiment, in every case the content of technical solution of the present invention is not departed from, the any amendment done above embodiment according to technical spirit of the present invention or equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
