Key device

Technical field

The present invention relates to a kind of key device, particularly a kind ofly integrate the key device that side direction key function and forward are browsed message key function.

Background technology

Along with the development of the consumption electronic products such as personal digital aid (PDA), intelligent mobile phone and palmtop computer, aspect volume not only towards light, thin, short, little design, also increasingly cheap in price, and these electronic products are also constantly released new additional function, and make simple conversation or electronic recording function of its non-past, still possess other several functions is arranged, such as supporting the multiple wireless data communication functions such as high speed Internet access, download games, wireless shopping etc., even has the function of global position system (GlobalPosition System, GPS).These electronic products not only make passing unreachable wireless telecommunications and network service become extremely easy to obtain, more will become following most of people's life and the important apparatus of working.

Yet, after the function of these electronic products is continued to increase, the integration problem at various uses interface will be accompanied by, especially each manufacturer develop successively and be used in the icon (icon) of choosing on its screen, and exactly so possess compatibility is arranged, often make the manufacturing firm of electronic product need make individually the key device of various types to measure, cause development cost to improve, and increased the assembling product difficulty.

Generally included the side direction function key and browsed the message key in the existing key device that is applied to electronic product, wherein the side direction function key is installed on the side of electronic product, adjust control in order to the size to the volume of electronic product, browsing the message key then is disposed on the electronic product, and with the periphery of electronic product one suitable spacing is arranged apart, mainly by the rotation in the front of browsing the message key is come the various messages of fast browsing from the screen of electronic product.

Existing side direction function key and to browse the message key mostly be to be made into respectively independently key-press module not only on the cost of material and mould, can't be reached and share and save cost, expends especially larger human cost in that the assembly process is installed; And quite dull in operating process, can not provide diversity to select and variation, to be improved.

Summary of the invention

The object of the present invention is to provide a kind of key device that side direction key function and forward are browsed message key function of integrating.

A kind ofly integrate the key device that side direction key function and forward are browsed message key function, comprise a circuit board, a knob, one first switch, a second switch, a wheel body and a cover cap, this knob is fixed on this circuit board; This first switch, second switch are connected in this circuit board and are positioned at the exterior circumferential place of this knob; This wheel body is set in this knob outer peripheral edges, and the outer rim of this wheel body forms respectively a plurality of protuberances; This hood section cover closes on this wheel body, and forms respectively thereon should the first switch and an elastic arm of this second switch; By rotation or the translation of this wheel body, can make these protuberances press respectively this elastic arm, and press respectively this first switch or this second switch and start by this elastic arm.

With respect to prior art, key device of the present invention is integrated with side direction key function and forward is browsed the message function, so that electronic product when assembling can utilize the present invention to replace in the past a plurality of key devices, can specifically save the cost of material, mould and assembling, simultaneously also provide key device multifarious mode of operation, increase the operation ease of electronic product.

Embodiment

Detailed description of the present invention and technology contents cooperate graphic being described as follows, and appended graphic only provide reference and explanation are not to limit the present invention.

See also Fig. 1 to shown in Figure 3, the invention provides a kind of key device 1 that side direction key function and forward are browsed message key function of integrating, this key device 1 mainly comprises a circuit board 10, a knob 20, one first switch 30, a second switch 40, a wheel body 50 and a cover cap 60.Knob 20 is installed on the circuit board 10, and with the circuit mutual conduction of circuit board 10, first and

second switch

30,40 can be respectively the assemblies such as magnetic reed switch, sensitive switch, its be configured in respectively knob 20 the exterior circumferential place and with the circuit mutual conduction of circuit board 10.

Knob 20 comprises a rotating shaft 21 and is socketed on a pad 22 of rotating shaft 21 outer peripheral edges, can control by the rotation start of rotating shaft 21 functions such as volume of an electronic product 8 (as shown in Figure 4).

Wheel body 50 is set in knob 20 outer peripheral edges, and its outer rim forms respectively the interval most protuberances 51 are set, and the protuberance 51 of present embodiment is semicolumn, obviously also can be other shape.

Cover cap 60 is by a meniscus shaped upper cover plate 61 and a pair ofly should upper cover plate 61 make the meniscus shaped lower cover 62 that cover closes and combine, this upper and

lower cover plate

61,62 part covers close on wheel body 50, and the compartment of terrain forms the elastic arm 611 of a plurality of corresponding the first switches 30 on upper cover plate 61, and lower cover 62 two ends respectively form the elastic arm 621 of a corresponding second switch 40; Lower cover 62 offers a groove 622 in elastic arm 611 positions corresponding to upper cover plate 61 in addition, passes for elastic arm 611.
