Abstract
A press key structure is arranged on a shell of an electronic device. A control element of the press key structure is controlled by an elastic force of an elastic arm; the control element is electrically contacted with a conduct element arranged on one side of the shell in normal state and keeps in a state of no output signal. When the control element is detached from the conduct element by pressing, the conduct element outputs a presetting signal to the electronic device. Since the action stroke between the control element and the conduct element is short, space needed in the press key structure is greatly reduced.

Embodiment
According to the disclosed press-key structure of the utility model, for being installed on the electronic installation, wherein said electronic installation comprises but is not limited to mobile phone, digital camera, the frivolous consumer level electronic product of MP3 player equal-volume, and in following detailed description of the present utility model, will be with digital camera as most preferred embodiment of the present utility model.Yet appended diagrammatic sketch only provides reference and explanation usefulness, is not in order to restriction the utility model.
Fig. 1, Fig. 2 A, and Fig. 2 B be depicted as schematic perspective view of the present utility model and carry out the generalized section of action.As shown in the figure, press-key structure 100 of the present utility model is installed on the housing 210 of an electronic installation 200, and housing 210 1 sides offer a perforate 211, and is provided with in the accommodation space of a circuit board 220 in housing 210.Wherein, press-key structure 100 includes an electric-conductor 110 and a control piece 120, and electric-conductor 110 is arranged on the inwall of housing 210 1 sides, and be surrounded on the peripheral position place of perforate 211, and by a signal line 230 and circuit board 220 electrically connects, and control piece 120 normalities remain in the initial position that electrically contacts with electric-conductor 110, and can push control piece 120 via the application of force, and make control piece 120 and electric-conductor 110 be separated from each other, to export a default signal.
Shown in Fig. 1 to Fig. 2 B, wherein electric-conductor 110 is a silver medal pulpboard, so that have favorable conductive character between electric-conductor 110 and the control piece 120, and control piece 120 has a press section 121 that is movably set in the perforate 211, and a self-pressing portion 121 extension downwards and normality and the electric-conductor 110 electrical contact sites 122 that contact, and press section 121 is exposed to outside the housing 210, push for the user, cause contact site 122 to break away from electric-conductor 110, and electric-conductor 110 is exported a signal simultaneously to electronic installation 200, to carry out the preset function of press-key structure 100.
Please continue to consult Fig. 1 to Fig. 2 B, the disclosed press-key structure 100 of the utility model also has two elastic arms 130, wherein an end of elastic arm 130 is arranged at the opposite side of the contact site 122 of control piece 120 corresponding to electric-conductor 110, and the other end of elastic arm 130 is linked on the sidewall of housing 210, makes control piece 120 normalities remain in the initial position that electrically contacts with electric-conductor 110 so that an elastic force to be provided.In addition, the contact site 122 of control piece 120 also is provided with a metal level 1221 with respect to a side of electric-conductor 110, electrically contact in order to electric-conductor 110 with silver slurry system, and also can be conductive material, makes contact site 122 of the present utility model, so can directly electrically contact, and not need to be in contact with one another by metal level 1221 and electric-conductor 110 with electric-conductor 110.
Shown in Fig. 2 A and Fig. 2 B, wherein control piece 120 is upwards pushed against by elastic force that elastic arm 130 provided, and makes metal level 1221 normalities on the contact site 122 keep electrically contacting with electric-conductor 110, to remain on the not state of output signal.When operator's application of force is pushed the press section 121 of control piece 120, will make that elastic arm 130 is stressed and downward distortion causes contact site 122 and electric-conductor 120 to break away from mutually, electric-conductor 120 is preset signal to circuit board 220 by signal line 230 outputs one simultaneously; After the operator will discharge control piece 120 applied force roads, the elastic arm 130 of stress deformation be involution to initial position, and the contact site 122 that drives control piece 120 returns back to initial position.
It should be noted that, press-key structure output signal of the present utility model is for to break away from control piece behind electric-conductor, electric-conductor is exported a default signal immediately to electronic installation and carry out default function, with existing button must be opposite with the action of exporting default signal by electrical contact.In addition, the default signal that press-key structure is exported can be output such as the signal of carrying out function signal, selection function signal, be familiar with the default signal that this operator also can export press-key structure and change the preset function that is designed to any existing press-key structure representative, do not exceed with the disclosed embodiment of the utility model.
Fig. 3 and Figure 4 shows that press-key structure of the present utility model is applied to the schematic perspective view and the partial enlarged drawing of digital camera.As shown in the figure, because in the market must be compact to the requirement of the volume of consumer level electronic product, and press-key structure 100 of the present utility model can significantly reduce the required space of installing, therefore quite be fit to be installed in as on the consumer level electronic installations 200 such as digital camera, to reach the purpose of reduction camera body thickness.
Compare with the key switch of prior art, the press-key structure that the utility model discloses will be arranged at housing one side in order to the electric-conductor of exporting default signal, and make the control piece normality electrically contact with electric-conductor by elastic arm, and with manner of execution in contrast to the prior art button, promptly via pushing control piece, so that control piece breaks away from electric-conductor and the default signal of output, thereby significantly reduce required space of press-key structure and stroke, simultaneously can avoid the user to drop electronic installation accidentally, and cause the damage of press-key structure.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
