Abstract

The utility model relates to a key apparatus and a keyboard, wherein the key apparatus comprises a membrane switch, the membrane switch is provided with at least one switch and a key cap membrane, above the switch there is correspondingly provided an arc bowl body, the key apparatus also comprises a key cap membrane, the key cap membrane is provided with a plurality of protruding key caps, the protruding key caps are corresponding to a first space and the arc bowl body, the first bowl body contains an actuating sheet prepared by a hard material, the plurality of protruding key caps form a second space together with each other for containing a framework, and when key caps are pressed downwards to push and press the corresponding actuating sheet, the actuating sheet touches downwards the corresponding arc bowl body, and the arc bowl body abuts against and actuates the corresponding switch. The key apparatus and the keyboard have the advantages of being low in height, light in weight and small in thickness; and if the key apparatus is used in cooperation with a touch screen, the thickness of the framework is smaller than the depth of the second space, such that the framework does not contact with the touch screen to damage the touch screen.

Description

Key device and keyboard

Technical field

The utility model is relevant for key device and keyboard, particularly about not having the low clearance key device and the keyboard of scissor support component.

Background technology

The low clearance key device is found in many consumption or information product, for example in communication handset, the mini calculator.

As far as knowing the general personage of this technology; Key device generally comprises an at least one keycap and a thin film switch, and keycap supplies the user to push, and has at least one switch on the thin film switch; And the top of switch is provided with arc bowl body, can conflict when arc bowl body is out of shape downwards and activates corresponding switch.Generally speaking, the height of key device is low more good more.

The utility model content

The technical problem that the utility model will solve is to provide a kind of utilization seldom low clearance, frivolous key device and keyboard of elements combination.

For addressing the above problem, the utility model provides a kind of key device, and it comprises: thin film switch, have at least one switch, and the top correspondence of switch is provided with arc bowl body; The keycap diaphragm has a plurality of keycaps that raise up, corresponding first space of protruding keycap, arc bowl body, and first space holds by what hard property material was constituted makes moving plate, and a plurality of keycaps that raise up form second space each other, supply to hold framework.When keycap is pressed when downward, the pairing moving plate of doing of this keycap pushing, this is made moving plate and touches pairing arc bowl body downwards, and arc bowl body is conflicted and is also activated pairing switch.

In the utility model one preferred embodiment, the keycap diaphragm is soft keycap diaphragm.

In the utility model one preferred embodiment, key device further comprises supporting bracket, is arranged at the below of thin film switch, and this frame fixation is on this supporting bracket.

In the utility model one preferred embodiment, arc bowl body is a metal arc bowl body or by macromolecule arc bowl body.

In the utility model one preferred embodiment, the thickness of framework is less than the degree of depth in this second space.

Another purpose of the utility model is to provide a kind of keyboard, and it comprises above-mentioned key device.

Key device that the utility model provides and keyboard have low clearance, frivolous benefit.Touch control type screen uses if key device is collocation, because the thickness of framework is less than the degree of depth in second space, framework also can not contact with touch control type screen and damages touch control type screen when folding.

Fig. 2 illustrates the constitutional diagram of Fig. 1 key device;

Fig. 3 illustrates the profile of Fig. 2 key device.

Embodiment

With reference to figure 1, a kind of key device of the utility model one embodiment comprises thin film switch 10, and it has at least one switch 101, and the top correspondence of switch 101 is provided with arc bowl body 103.With reference to Fig. 3; This key device comprises keycap diaphragm 20; Keycap diaphragm 20 has a plurality of keycaps that raise up 206, corresponding first space 204 of each protruding keycap 206, arc bowl body 103, and each first space 204 holds by what hard property material was constituted makes moving plate 208; These a plurality of keycaps that raise up 206 form second space 202 each other, as shown in Figure 3.Second space 202 supplies to hold framework 210.Make moving plate 208 and can use dijection moulding (doube injection molding) to be integral shape, or after separating moulding earlier, utilize glue to be fixed together again with keycap diaphragm 20.

And be pressed when downward when keycap 206 is stressed, it pushes the pairing moving plate 208 of doing, and this is made moving plate 208 and touches pairing arc bowl body 103 downwards.Arc bowl body 103 is then conflicted and is activated pairing switch 101.

According to an embodiment, keycap diaphragm 20 is to be made up of flexible material, like rubber, silica gel.Key device further comprises supporting bracket 30, is arranged at the below of thin film switch 10, and as shown in Figure 3, this framework 210 utilizes fixed leg 2101 to be fixed on this supporting bracket 30, with fixing keycap diaphragm 20.The end of fixed leg 2101 can make it become the shape of mushroom head with the heat mode of melting.

According to an embodiment, this arc bowl body 103 is to constitute by metal or by macromolecular material.The thickness of this framework 210 can be less than the degree of depth in this second space 202, as shown in Figure 3.Therefore if key device is a collocation touch control type screen (not illustrating) when using, even if key device under folded state, keycap 206 contacts with touch control type screen, framework 210 also can not contact with touch control type screen and damage touch control type screen.

With the key device that can obtain being shown in Fig. 2 after the elements combination of Fig. 1.

Be illustrated in figure 3 as the profile of the key device of Fig. 2, clear again position and the connection relationship that discloses above-mentioned each necessary element.Hence one can see that, and the utility model provides a kind of utilization seldom low clearance, frivolous key device of elements combination really.

Since the existence and the location of framework 210, the effect of generation fixed pivot, and the position when being pressed as if keycap 206 is positioned at the edge of keycap 206, still can correctly touch corresponding arc bowl body 103.

Cooperating diagram can understand the utility model by above-mentioned explanation can reach the technical problem that utility model institute desire solves really, therefore have practicality.

The utility model is described by above-mentioned related embodiment, yet the foregoing description is merely the example of implementing the utility model.Must be pointed out that the embodiment that has disclosed does not limit the scope of the utility model.On the contrary, change and the retouching in spirit that does not break away from the utility model and scope, done all belong to the scope of patent protection of the utility model.
