As shown in fig. 1 and 2, for the utility model discloses a key sealing structure, especially a cell-phone side volume, on & off switch's seal structure, it includes casing 10, button 20, silica gel cover 40, it presses keyway 11 to have seted up one on casing 10, this key groove 11 runs through to the surface by casing 10's internal surface, button 20 is pressed keyway 11 by the inboard embedding of casing 10 in, make button 20 can prolong the extending direction who presses keyway 11 and move for casing 10, simultaneously, be provided with stop gear between button 20 and the casing 10, this stop gear is used for preventing that button 20 from breaking away from the outside opening of button groove 11, in order to guarantee button 20's normal use. The silica gel sleeve 40 covers the inner surface of the shell 10, is connected with the inner surface of the shell 10, and the silica gel sleeve 40 is in close fit with the shell 10, the silica gel sleeve 40 can be adhered to the inner surface of the shell 10 by using the gum 30, and the gum 30 is provided with the through hole 31 avoiding the key 20, so that the silica gel sleeve 40 is kept in close fit with the shell 10 while the silica gel sleeve 40 is connected with the shell 10, and particularly, the silica gel sleeve 40 is in close fit with the silica gel sleeve 40 at the position of the periphery of the key slot 11 on the inner surface of the shell 10, namely, the inner space of the shell 10 is closely separated from the key slot 11 by using the silica gel sleeve 40; the silicone sleeve 40 is provided with a matching portion 42, the matching portion 42 abuts against the inner side of the key 20, when the key 20 is pressed, the inner side of the key 20 pushes the matching portion 42, so that the matching portion 42 triggers the key FPC located inside the housing 10, and in turn, the mobile phone is correspondingly controlled.

When the structure is installed, the key 20 is embedded into the key groove 11 from the inner side of the shell 10, the key 20 is prevented from being separated from the outer opening of the key groove 11 by the limiting mechanism, then the back adhesive 30 is attached to the inner surface of the shell 10, and finally the silica gel sleeve 40 is attached to the back adhesive 30. Because the key pressing groove 11 is covered by the silica gel sleeve 40, that is, the silica gel sleeve 40 seals and isolates the key pressing groove 11 from the inside of the shell 10, the path of dust and water entering the inside of the shell through the key pressing groove 11 is blocked, and meanwhile, the flexible silica gel sleeve 40 can be well attached to the inner surface of the shell 10, so that the silica gel sleeve 40 and the shell 10 at the outer periphery of the key pressing groove 11 have better sealing performance.

It should be noted that, the present invention can not only connect the silica gel cover 40 and the housing 10 through the above-mentioned back adhesive 30, but actually, the silica gel cover 40 and the housing 10 can also be connected by other types of adhesives or by other sealing connection methods.

In a preferred embodiment, the silicone sleeve 40 is provided with an elastic connecting arm 43 connected between the main body portion of the silicone sleeve 40 and the matching portion 42, the elastic connecting arm 43 is a structure easy to deform, when the key 20 is pressed outside the housing 10, the inner side of the key 20 presses the matching portion 42, so that the elastic connecting arm 43 deforms, that is, the elastic connecting arm 43 is easy to deform, thereby reducing resistance to the key 20 when the key 20 is pressed, and at the same time, when the external force on the key 20 is removed, the elastic stress generated after the elastic connecting arm 43 deforms is utilized to assist the key 20 to reset. The thickness of the elastic connecting arm 43 is smaller than the thickness of the main body of the silicone sleeve 40, that is, a portion with smaller thickness is disposed between the matching portion 42 and the other portions of the silicone sleeve 40 on the silicone sleeve 40 to form the elastic connecting arm 43, and when the key 20 pushes the matching portion 42 on the silicone sleeve 40 with smaller thickness, the elastic connecting arm 43 has a relatively larger deformation amount, and the main body of the silicone sleeve 40 has no deformation or small deformation, so that the silicone sleeve 40 is not easy to fall off from the inner surface of the housing 10. Specifically, a groove may be formed on each of the two faces of the silicone sleeve 40 at the periphery of the fitting portion 42, and the elastic connecting arm 43 is located between the grooves on the two faces of the silicone sleeve 40; of course, the silicone rubber cover 40 may be provided with a groove only on one surface thereof, as long as the thickness of the elastic connecting arm 43 can be reduced.

In another preferred embodiment, the present invention is provided with a shoulder 21 protruding from the periphery of the key 20, the shoulder 21 is hung on the portion of the housing 10 located at the periphery of the key slot 11, that is, the shoulder 21 and the portion of the housing 10 located at the periphery of the key slot 11 form the above-mentioned limiting mechanism to prevent the key 20 from being separated from the outside opening of the key slot 11; further, a concave position 41 is arranged on the silicone rubber sleeve 40, the convex shoulder 21 is embedded in the concave position 41, when the key 20 is pressed, the convex shoulder 21 moves in the concave position 41, that is, the concave position 41 is used for avoiding the convex shoulder 21, so that the situation that the silicone rubber sleeve 40 is pressed when the key 20 is pressed is avoided, and the connection tightness between the silicone rubber sleeve 40 and the shell 10 is further prevented from being influenced under the condition that the key 20 is pressed for multiple times.

In other embodiments, the utility model discloses be provided with a boss 22 in the inboard of button 20, corresponding, cooperation portion 42 is provided with the arch towards the one side of button 20, and the arch supports the top on boss 22, and like this, when pressing button 20, boss 22 pushes away the top arch of cooperation portion 42, has strengthened feeling when button 20 uses.

The utility model discloses an electronic equipment has included foretell key seal structure, and this electronic equipment is not only limited to foretell cell-phone, and it can also be panel computer, notebook computer, intelligent wearing equipment etc..

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
