As shown in Figure 2 and Figure 3, housing 1 cross section in "
" shape, have a rectangular channel at the upper surface center of housing 1, for installing silica gel push-button 3 and preventing housing 1 and button circuit board 2 reverse side device from interfering.Be provided with the annular boss pasting foam 7 in this rectangular channel surrounding, have the annular groove storing fluid sealant 6 in this annular boss arranged outside.The degree of depth of annular groove leaves certain distance a between button circuit board 2 and housing 1 after should ensureing to install button circuit board 2 and silica gel push-button 3, and a value is the height after foam 7 compresses.
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, silica gel push-button 3 for cross section in "
" rectangular-shaped piece of shape, match with the shape of cross section structure of housing.At the upper surface of silica gel push-button 3 along uniform five rectangular boss for finger presses of horizontal center line, within one week, being provided with rectangular boss upper surface angle around rectangular boss is the skew wall of 45 °, for increasing the elasticity of silica gel push-button 3.Silica gel push-button 3 lower surface along horizontal center line uniform five for touching the inverted cone post of shell fragment 5, the axis of the rectangular boss that the axis of each circular cone post is corresponding with it respectively overlaps.Have the rectangular channel of mounting elastic sheet coherent film 4, shell fragment 5 and button circuit board 2 at the lower surface center of silica gel push-button 3, the degree of depth of rectangular channel is slightly larger than the thickness of button circuit board 2.The annular boss that can be embedded in housing 1 annular groove is provided with in the lower surface outward flange surrounding of silica gel push-button 3.
As shown in Figure 8, shell fragment coherent film 4 is gular transparent plastic film, its length and width are dimensioned slightly smaller than the length and width size of the rectangular channel of silica gel push-button 3 lower surface, two-sided standby glue, be respectively used to shell fragment coherent film 4 glued joint with silica gel push-button 3 and shell fragment 5 and bond, shell fragment coherent film 4 two ends are arranged with steam vent, avoid silica gel push-button in use procedure to play bulging phenomenon.
As shown in Fig. 1, Fig. 9, Figure 10, the sheet metal of shell fragment 5 to be vertical sections be cambered surface, the height of cambered surface is the impulse stroke of shell fragment 5, and cambered surface is upwards heaved.Shell fragment 5 and shell fragment coherent film 4 lower surface glued joint and bond, and shell fragment 5 is uniform along shell fragment coherent film 4 horizontal center line, and the quantity of shell fragment 5 is consistent with the number of keys of silica gel push-button 3, and the vertical center line of shell fragment 5 overlaps respectively with the axis of silica gel push-button 3 inverted cone post.Can contact with button circuit board when shell fragment is squeezed, automatically reset after distress resolves.
The installation process of the present embodiment is: during assembling, and foam 7 is bonded on the annular boss of housing 1, and fluid sealant 6 is coated in the annular groove of housing 1.The shell fragment coherent film 4 be bonded together and shell fragment 5 are bonded in the rectangular channel at silica gel push-button 3 lower surface center by another of shell fragment coherent film 4 for glue face again, button circuit board 2 is placed on the below of shell fragment 5, then the button circuit board 2 assembled, silica gel push-button 3, shell fragment coherent film 4, shell fragment 5 are put into together the groove of housing 1, even pressing silica gel push-button 3 upper surface also leaves standstill the suitable time, reaches the object that silica gel push-button 3 is fitted completely with housing 1.
The waterproof principle of the present embodiment is: during installation, silica gel push-button 3 applies certain pressure, make the wall of silica gel push-button lower surface outer peripheral annular boss surrounding closely be squeezed on the outer peripheral cell wall of the annular groove of housing 1, it is inner that the interference fit of silica gel push-button 3 and housing 1 makes water be difficult to enter into housing 1 along the gap between silica gel push-button 3 and housing 1.If hydraulic pressure is larger, water enters the gap between silica gel push-button 3 and housing 1, now, hydraulic pressure can extrude the wall of the outer peripheral annular boss of silica gel push-button lower surface, the pressure direction of water points to the inside of silica gel push-buttons 3 along four peripheral wall surfaces normals of this annular boss, what the inside groove wall of the annular groove of this annular boss and housing 1 will be fitted like this is tight, water can only be rested at most in the annular groove of housing 1, and this annular groove can not be crossed enter in the rectangular channel at housing 1 upper surface center, hydraulic pressure is larger, the inside groove wall of the annular boss of silica gel push-button 3 and the annular groove of housing 1 is just fitted tighter, water resistance is better, self-packing function is reached by above mode.Meanwhile, fluid sealant 6 makes silica gel push-button 3 and housing 1 fit further, reaches the effect of the second resealing.This double sealing structure, reaches the effect of effective waterproof.
The course of work of the present embodiment is: the upper surface of pressing silica gel push-button 3, the lower surface of the inverted cone post of silica gel push-button 3 contacts with shell fragment 5, and shell fragment 5 strain occurs and contacts with button circuit board 2, circuit ON, and electronic equipment is able to work.
Silica gel push-button of the present utility model is installed from electronic device exterior, is embedded in housing groove, is fixed on housing by the interference fit of silica gel push-button and housing and fluid sealant by silica gel push-button, compared with in-built silica gel push-button, take up room little, structure is simple, flexible design, installs and removes easy.
