Embodiment
About aforementioned and other technology contents, characteristics and effect of the present utility model, in the detailed description of a following cooperation preferred embodiment with reference to the accompanying drawings, can clearly present.
Consult Fig. 3, Fig. 4, Fig. 5, the Waterproof push-button 2 of a preferred embodiment of the utility model comprises the rigid support part 23 that a keying body 21, a water proof ring 22 and are combined in keying body 21.Keying body 21 is made for for example rubber or silica gel etc. have elastic material, it comprises a cap portion 211, at least one portion 212 and one first dish portion 213 of pressing, cap portion 211 comprises that a roof 214 and down extends in the form of a ring surrounding wall 215 by roof 214, the first dish portion 213 is by the horizontal expansion outward of surrounding wall 215 root edges, in the present embodiment, the first dish portion, 213 profiles are roughly rectangular, and its bottom surface is protruded respectively along outer rim place, length limit, both sides and is formed with a flange 216, certainly, the shape and the quantity of flange 216 are not exceeded with present embodiment, the profile of visual keying body 21 and changing.Press portion 212 and be by down extending and centered on by surrounding wall 215 in roof 214 bottom surfaces.Water proof ring 22 is convexly set in the outside wall surface of surrounding wall 215 and distributes in the form of a ring, and in the present embodiment, water proof ring 22 is to be connected with keying body 21 one-body moldedly.
In the present embodiment, the mode that rigid support part 23 combines with keying body 21, can be to distinguish after forming press key body 21 and the rigid support part 23, again rigid support part 23 is combined in keying body 21 in the mode of hot pressing, or first moulding rigid support part 23, again to rigid support part 23 with in-molded mode forming press key body 21.
Waterproof push-button 2 can be for being arranged on an electronic device housing 3 for example, this electronic device housing 3 comprises that a shell wall 31 and is arranged on the perforate 32 of shell wall 31, and shell wall 31 has an inner face 311 and an outside of exposing 312, when Waterproof push-button 2 is arranged on electronic device housing 3, the first dish portion 213 of keying body 21 is attached to the inner face 311 of shell wall 31,211 in cap portion be stretch into perforate 32 and its roof 214 by perforate 32 expose to shell wall 31 outside 312 and can be for pushing, water proof ring 22 is connected to the interior peritreme of perforate 32.
When the roof 214 of cap portion 211 was pressed, the part that roof 214 is not provided with the portion of pressing 212 can produce distortion, made the portion of pressing 212 press the circuit unit 33 that puts in place in electronic device housing 3 toward intrinsic displacement.The circuit unit 33 of indication is arranged on the touch-pressure switch on the circuit board 331 herein.
It should be noted that, because keying body 21 is to be made by the rubber-like material, so setting by support portion 231, strengthened the rigidity of surrounding wall 215, and because support portion 231 to small part and water proof ring 22 overlaps, therefore, just in the time of can making water proof ring 22 be connected to the interior peritreme of perforate 32, surrounding wall 215 is not easy to be out of shape toward the direction that presses portion 212 because water proof ring 22 is connected to the relation of peritreme in the perforate 32, thereby influence the tightness degree that water proof ring 22 is connected to peritremes in the perforate 32, in other words, water proof ring 22 can be supported in support portion 231, allows water proof ring 22 more closely be connected to peritreme in the perforate 32, keeps its waterproof effect, and many more with the part that water proof ring 22 altitude range a overlap when support portion 231, its effect that can support water proof ring 22 is also good more.In addition, closely be connected to the frictional force that interior peritreme produced of perforate 32, also can avoid Waterproof push-button 2 to produce easily and break away from electronic device housing 3 with respect to the displacement of perforate 32 by making water proof ring 22.
Another effect of support portion 231 is, when cap portion 211 was subjected to pushing, because the relation of support portion 231, cap portion 211 can't whole collapse-deformation, and when pushing finger still can indistinctly feel support portion 231 the apical margin profile and the sense of touch of pushing is arranged.
In addition, in the present embodiment, because the second dish portion 232 of rigid support part 23 is the first dish portions 213 that are combined in keying body 21, when keying body 21 is arranged on electronic device housing 3, the second dish portion 232 also can increase the rigidity of the first dish portion 213 and support to arrive at shell wall 31 inner faces 311, avoids keying body 21 just to be pulled out by the direction toward shell wall 31 outsides 312 easily.
Explanation is more again, because keying body 21 is the circuit units 33 that correspond to 3 li of electronic device housings when being arranged on the perforate 32 of shell wall 31, formation by two flanges 216, then can dwindle the distance between keying body 21 and the circuit board 331, in the time of can also avoiding whole Waterproof push-button 2 to be pressed, owing to whole easily toward electronic device housing 3 intrinsic displacements with the distance of circuit board 331 keying body 21 that makes too far away.
In other enforcement aspect, if the intensity of keying body 31 first dish portions 213 is enough, rigid support part 23 also can omit the part of the second dish portion 232.
After tested, electronic device housing 3 Waterproof push-button 2 that present embodiment is set can reach the classification of waterproof of IPX7.
In sum, the utility model utilizes the setting of rigid support part 23, strengthen the waterproof effect of Waterproof push-button 2, because the structure of rigid support part 23 is simple thereby manufacturing cost is lower, and rigid support part 23 is directly to be combined in the keying body 21, its needed built-up time and required occupation space also can significantly reduce, so known compared to Fig. 1 or Fig. 2 no matter, Waterproof push-button 2 of the present utility model all has the enhancement on the effect really.
But above-described only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, be that every simple equivalent of being done according to the utility model application right claimed range and specification disclosure changes and modifies, all still belong in the scope that the utility model patent contains.
