Abstract
The utility model relates to a side key. The side key comprises a side key main body. The upper end and the lower end of the side key body are connected with a double-material-injection front shell and a double-material-injection back shell respectively through soft elastic arms; the left side of the side key main body is provided with a side-key switch; a main PCB is arranged above the side-key switch; and an inclined angle between one soft elastic arm and a bottom surface of the double-material-injection front shell and an inclined angle between the other soft elastic arm and a top surface of the double-material-injection back shell are acute angles. The side key of the utility model is advantageous in that a certain gradient is designed between one soft elastic arm and the double-material-injection front shell, between the other soft elastic arm and the double-material-injection back shell, and between two soft elastic arms and the side key main body, such that space and length are reserved for the movement of the soft elastic arms, as a result, no tensile deformation is produced in a triggered process of the side key, and a resilience force which is produced because of the stretching of the soft elastic arms can be eliminated, and therefore, the problems of hard feel and difficulty in operation of the double-material-injection pressing side key can be solved.
Description
Technical field
The utility model relates to a kind of side switch.
Background technology
Mobile phone, digital camera, the three anti-electronics devices such as MP3 and MP4 adopt double-material injection-molding to solve the problem of side switch waterproof more, by doing the elastic arm of button and housing coupling part thin, when finger presses, force stretcher strain by making flexible glue, could trigger side switch, be that side switch 1 is generally positioned between double-material injection-molding fore shell 2 and the double-material injection-molding back cover 3 (as shown in Figure 1), the flexible glue elastic arm 4 of side switch 1 is connected with the double-material injection-molding back cover with double-material injection-molding fore shell 2 respectively and is connected and vertical, when using function of side key (as shown in Figure 2), need it is pressed, side switch 1 meeting this moment is to the medial movement of double-material injection-molding fore shell 2 and double-material injection-molding back cover 3, flexible glue elastic arm 4 simultaneously stretches, promote inner side key switch 5, simultaneously control information is transferred to main PCB plate 6 to realize its function.And flexible glue elastic arm 4 itself has very strong resilience force, needing to cause the user with very large power function of side key is triggered.Because of various materials certain fatigue strength is arranged all simultaneously, thus the push button longevity of this structure is also shortened greatly, and Boardy Feeling, be difficult to operation.
The utility model content
The purpose of this utility model provides a kind of side switch, solves side switch and presses the tensile force that flexible glue elastic arm imposed deformation produces in the process, cause to press the side switch feel partially hard, the defective that useful life is short.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of side switch, comprise the side switch main body, the up and down two ends of described side switch main body are connected with the double-material injection-molding back cover with the double-material injection-molding fore shell respectively by the flexible glue elastic arm, the left side of side switch main body is provided with side key switch, the top of side key switch is provided with the main PCB plate, described flexible glue elastic arm respectively and the angle between double-material injection-molding fore shell bottom surface and the double-material injection-molding back cover end face be acute angle.
The beneficial effects of the utility model are: design certain slope respectively and between double-material injection-molding fore shell, double-material injection-molding back cover and the side switch main body by the flexible glue elastic arm, reserve space and the length of the motion of flexible glue elastic arm, make it in trigger process, not produce any stretcher strain, eliminated the resilience force that produces because of stretching flexible glue elastic arm, thereby solved the Boardy Feeling that double-material injection-molding is pressed side switch, the problem of difficult operation.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation of existing side switch;
Fig. 2 is the use state reference map of existing side switch;
Fig. 3 is the structural representation of the described side switch of the utility model embodiment;
Fig. 4 is the use state reference map of the described side switch of the utility model embodiment.
Among the figure:
1, side switch; 2, double-material injection-molding fore shell; 3, double-material injection-molding back cover; 4, flexible glue elastic arm; 5, side key switch; 6, main PCB plate; 11, side switch main body; 12, flexible glue elastic arm; 13, double-material injection-molding fore shell; 14, double-material injection-molding back cover; 15, side key switch; 16, main PCB plate.
Embodiment
As shown in Figure 3-4, the described a kind of side switch of the utility model embodiment, comprise side switch main body 11, are connected with the double-material injection-molding back cover with double-material injection-molding fore shell 13 respectively and are connected by flexible glue elastic arm 12 in the up and down two ends of described side switch main body 11, the left side of side switch main body 11 is provided with side key switch 15, the top of side key switch 15 is provided with main PCB plate 16, described flexible glue elastic arm 12 respectively and the angle between double-material injection-molding fore shell 13 bottom surfaces and double-material injection-molding back cover 14 end faces be acute angle.
During use, press side switch main body 11, side switch main body 11 promotes side key switch 15, and control information is transferred to main PCB plate 16 to realize its function.The angle between double-material injection-molding fore shell 13 bottom surfaces and the double-material injection-molding back cover 14 is identical respectively not press flexible glue elastic arm 12 in side switch main body 11 and two states pressing side switch main body 11 in this process, and press in the process whole, the stretching phenomenon does not appear in flexible glue elastic arm 12, flexible glue elastic arm 12 respectively and the angle optimum between double-material injection-molding fore shell 13 bottom surfaces and the double-material injection-molding back cover 14 be 16 °, pressing stroke (side switch main body displacement) is 0.3mm, arrange, the optimization length of glue elasticity arm 12 is 0.7mm, when being pressed state, the length of glue elasticity arm 12 also is 0.71mm, eliminated the resilience force that produces because of stretching flexible glue elastic arm, thereby solved the Boardy Feeling that double-material injection-molding is pressed side switch, the problem of difficult operation.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
