Embodiment

Invention broadly provides a kind of mobile terminal and side key structure thereof, main purpose be by the inner region of the housing of mobile terminal and space outerpace completely isolated, to make it have good waterproof and dust reduction capability.It should be noted that, be all that embodiment illustrates with mobile phone in full below, but mobile terminal of the present invention is not limited to mobile phone, also comprises the mobile terminal that all have side key structure.

Below in conjunction with accompanying drawing 1 ~ 7 and embodiment, the present invention is described in detail.

Fig. 1 is the decomposing schematic representation of side key structure one embodiment of mobile terminal of the present invention.As shown in Figure 1, the side key structure of the present embodiment comprises housing 110, side switch 120 and side switch silica gel 130.

Wherein, side switch 120 comprises press section 121 and is located at the shirt rim portion 122 at edge, press section 121.

Housing 110 comprises the first housing 111 and the second housing 112, also can be described as protecgulum and bonnet, but be not limited thereto, and the sidepiece of the second housing 112 offers side switch hole 113.

Fig. 2 is the partial schematic diagram of the first housing 111 shown in Fig. 1, consults Fig. 2, the first housing 111 is provided with support portion 114, U-shaped groove 115, the first side wall 116, second sidewall 117, first reference column 118 and the second reference column 119.

Fig. 3 is the enlarged diagram of the side switch silica gel 130 shown in Fig. 1.Consult Fig. 3, side switch silica gel 130 comprise main part 131, be arranged at the first boss 132 of main part 131 both sides with the second boss 133 (see figure 1), first extension 134 vertical with main part 131 with the second extension 135, be arranged at main part 131 two ends and three extension 136 vertical with the first extension 134 and the 4th extension 137.Wherein, the present embodiment preferred side switch silica gel 130 is one-body molded.In addition, the first boss 132 and the respective magnitude setting of the second boss 133 are not limited to two shown in figure, and those skilled in the art can be arranged according to actual needs.

Fig. 4 is the side sectional view after the combination of side key structure shown in Fig. 1, and Fig. 5 is the partial enlarged drawing of side key structure shown in Fig. 4.Consult Fig. 4 and Fig. 5, in side key structure after combining, the press section 121 of side switch 120 to be inserted in side switch hole 113 and spacing by shirt rim portion 122.

The main part 131 of side switch silica gel 130 is positioned at housing 110, and is completely cut off by housing 110 for inner region A and side switch active region B.

First extension 134 extends towards side switch active region B, and the first extension 134 is held in groove 115 by the second housing 112; Second extension 135 extends towards inner region A, and support portion 114 by the second extension 135 pressure holding on the second housing 112.

Now, incorporated by reference to Fig. 2, Fig. 3 and Fig. 5,3rd extension 136, the 4th extension 137 correspondence are inserted in groove 115, and the 3rd extension 136 is tightly held between the first side wall 116 and the first reference column 118, the 4th extension 137 is tightly held between the second sidewall 117 and the second reference column 119.

For the side key structure of the mobile terminal shown in Fig. 4, because housing 110 completely cuts off for inner region A and side switch active region B by side switch silica gel 130, and side switch 120 is positioned at side switch active region B, therefore no matter how user presses side switch 120, the foreign matter such as dust and the globule only can enter side switch active region B from the gap between press section 121 and side switch hole 113, can not enter in inner region A, thus there is good waterproof and dust reduction capability, and side switch 120 and the side switch silica gel 130 of the present embodiment are not fixedly installed, be compared to the expense that prior art saves bicolor injection mould, reduce production cost.

In addition, in the side key structure after combination shown in Fig. 4, the first boss 132 is towards diaphragm switch 200, and the second boss 133 is towards side switch 120.When user presses side switch 120, first boss 132 and the second boss 133 match and conduct to for the displacement pressed by side switch 120 diaphragm switch 200 be carried on support portion 114, the conductive base (not shown) that now the first boss 132 is built-in can be electrically connected with diaphragm switch 200, the displacement pressing side switch 120 is sent to as electronic signals the treatment system of mobile terminal.

Present invention also offers a kind of mobile terminal, Fig. 6 is the decomposing schematic representation of mobile terminal of the present invention, and Fig. 7 is the schematic diagram after the combination of mobile terminal shown in Fig. 6.As shown in Figure 6 and Figure 7, this mobile terminal has the side key structure of above-described embodiment, by the inner region of housing and space outerpace completely isolated, therefore there is good waterproof and dust reduction capability equally, and side switch is separated with side switch silica gel and is fixedly installed, save the expense of bicolor injection mould in prior art, reduce production cost.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
