Description

The two press-key structures of side direction on the handheld device

Technical field

The utility model relates to the handheld device field, and particularly handheld device side direction press-key structure field specifically is meant the two press-key structures of side direction on a kind of handheld device.

Background technology

In at present commercially available mobile phone, multimedia function is more and more abundanter, and volume is more and more compact.Accordingly the structural requirement of button is also had higher requirement.The two buttons of common side direction divide two kinds of forms according to the construction of switch difference: adopt microswitch and the structure that adopts METAL DOME, see also shown in Figure 1, the structure basically identical of its key main body 1, operation principle is: key main body 1 is placed in the casing 2 by two location notchs 3 on the casing 2, the side contacts with the contact or the DOME of microswitch 4 on one side, during work, hand pressing button, make two contact contact conducting work, after openhanded the opening, lean on microswitch 4 elastic force own that key main body 1 is backed down and reset.

Its simplified structure model sees also shown in Figure 2.Concerning the two buttons of side direction of most of button length L long (with respect to the width of finger), this structure is very easy and practical, so adopted by present most of commercially available product.

Along with compact popular of mobile phone, the length L of side direction button also shortens thereupon, when if the width of button length L and finger is suitable, at this moment as adopting said structure, might cause two buttons to connect simultaneously, do not reach user's desired operation requirement, therefore, need a kind of new version to solve such problem.

The utility model content

The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, provide a kind of can not cause the misoperation of two keys under pressing simultaneously, accurate positioning, simple in structure, easy to make, save inner space, the applicable surface two press-key structures of side direction on the handheld device comparatively widely.

In order to realize above-mentioned purpose, the two press-key structures of side direction have following formation on the handheld device of the present utility model:

The two press-key structures of side direction on this handheld device, two microswitches and the key main body that comprise housing, the enclosure interior side direction of handheld device, its main feature is, described case side to ad-hoc location have location hole, the location hole edge has location notch, described location hole middle part has a stopper, described key main body is arranged in the described location hole by location notch and stopper, it is the lever construction of axle that described key main body forms with the stopper, and this position, key main body both ends is corresponding with the contact of two microswitches respectively.

The stopper of the two press-key structures of side direction is the small cylinder with cylinder end face on this handheld device, and inboard, described key main body middle part has cylinder shape groove corresponding with it.

The outside, both ends of the key main body of the two press-key structures of side direction has convex shape on this handheld device.

The two press-key structures of side direction on the handheld device of this utility model have been adopted, guarantee that with the way that forms balance pivot two buttons can not be switched on simultaneously as stopper owing in the middle of key main body, increase support column, and the cylinder that utilizes support column to carry out key main body is located and end face is spacing, thereby make the user can not cause misoperation, action each time has only a button job; The side direction of handheld device can be utilized self structure location, spacing simultaneously, has simplified the associated shell structure, and easy to manufacture; Moreover, two press-key structures of this utility model make the microminiaturization of mobile phone side direction press-key structure, have satisfied the compact demand of mobile phone, and the scope of application is comparatively extensive, bring great convenience for people's life.

Embodiment

In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.

See also Fig. 3 and shown in Figure 4, the two press-key structures of side direction on this handheld device, the housing 11, housing 11 private sides that comprises handheld device to two microswitches 12 and key main body 13, wherein, the ad-hoc location of described housing 11 side direction has location hole, the location hole edge has location notch 14, described location hole middle part has a stopper 15, in the present embodiment, this stopper 15 is for having the small cylinder 15 of cylinder end face, and inboard, described key main body 15 middle part has cylinder shape groove corresponding with it; Described key main body 13 is arranged in the location hole of described housing 11 by location notch 14 and stopper 15, it is the lever construction of axle that described key main body 13 forms with stopper 15, and this position, key main body 13 both ends is corresponding with the contact of two microswitches 12 respectively.

Moreover, the comfortable feel when guaranteeing that the user operates this pair button, the outside, both ends of described key main body 13 also has the convex shape that matches with the finger shape, makes pressing by action of finger more accurately put in place.

In the middle of reality is used, one end of hand pressing key main body 13, because of button connects together by stopper 15 and housing 11, button rotates around balance pivot, one end is pressed to the contact on the microswitch 12, makes microswitch 12 closed conductings, and the other end and microswitch 12 disengage, thereby realize two key interlockings, guarantee to have only 12 contacts of a microswitch at every turn.After openhanded the opening, lean on microswitch 12 elastic force own that key main body 13 is backed down to reset and keep in touch.

Because the stroke of switch generally has only 0.2mm～0.3mm, therefore can not cause difficulty to the structure of shell.

By foregoing description as can be seen, key main body 13 is passed through the hole with housing 11---and the cylinder location connects together, and small cylinder 15 end faces have limited the axial location of key main body 13.During work, key main body 13 is rotated around small cylinder 15 and is realized two key switch interlockings.

Utilize above-mentioned thought simultaneously,, many different implementation methods can be arranged by suitable distortion.

The two press-key structures of side direction on the above-mentioned handheld device have been adopted, guarantee that with the way that forms balance pivot two buttons can not be switched on simultaneously as stopper 15 owing in the middle of key main body 13, increase support column, and the cylinder that utilizes support column to carry out key main body 13 is located and end face is spacing, thereby make the user can not cause misoperation, action each time has only a button job; The side direction of handheld device can be utilized self structure location, spacing simultaneously, has simplified the structure of associated shell 11, and easy to manufacture; Moreover, two press-key structures of this utility model make the microminiaturization of mobile phone side direction press-key structure, have satisfied the compact demand of mobile phone, and the scope of application is comparatively extensive, bring great convenience for people's life.

In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
