Description
[technical field]
The utility model is the button that is used for portable electron device about a kind of, refers in particular to a kind of multidirectional key that is used for portable electron device.
[background technology]
The keyboard of portable electron device such as personal digital assistant, mobile phone, beep-pager and calculator all comprises multidirectional or multifunction push key usually, and multidirectional or multifunction push key comprises that upper and lower both direction or upper and lower, left and right four direction are to realize the scroll-up/down demonstration of information on the display screen or moving of screen cursor more.Described multidirectional or multifunction push key mostly is the one design, and its middle part has been provided with the projection of leverage, and when pushing a direction, slightly perk electrically contacts thereby only form on the direction of being pushed other directions owing to protruding leverage.The button that No. the 00124301.2nd, Chinese patent application and United States Patent (USP) are disclosed for the 6th, 157, No. 323 is this type of multidirectional key.
Chinese patent application has disclosed another kind of multidirectional key 99110868.X number, at the above-mentioned multidirectional key middle part of upper and lower both direction that comprises one hole is set, ccontaining one relatively independent center button in the hole is provided with the assembly of tool pivot action and the multidirectional key upper/lower terminal can be pressed respectively in the both sides at multidirectional key middle part.Like this, just formed multidirectional key with three directions in upper, middle and lower.
This type of button can be user-friendly and can be reduced button and take up space, thereby has in the industry cycle obtained using widely.But owing to need to adopt the projection of tool leverage or pivot so that braking mutually between all directions of multidirectional key, and design is restricted.Around the button of center, design the multidirectional key of three or three above directions of tool when need, then be difficult to be provided with the projection or the pivot of tool leverage, and multidirectional key is an integral body, need to adopt the flexible made of tool more, even so, still be difficult to eliminate influencing each other between all directions button fully, and easily cause misoperation, the conductive contact of button bottom the conducting simultaneously and equipment that causes linking to each other with keyboard breaks down.
[summary of the invention]
The purpose of this utility model is to provide a kind of multidirectional key that prevents misoperation.
The purpose of this utility model is achieved in that the utility model multidirectional key comprises a plurality of key bodies, elastic washer and contact layer.Separate between each key body, its bottom is provided with chamber and location notch.Elastic washer comprises that spacer ring body reaches by a plurality of elastic arms that stretch out on the spacer ring body.Contact layer comprises body and a plurality of joint portions corresponding with key body, and the top, joint portion is provided with projection.The spacer ring body of elastic washer is sheathed on the outside, joint portion, and elastic arm is placed between the joint portion.Key body places on the joint portion, and the projection of joint portion is placed in its chamber, and elastic arm is placed in its location notch.When multidirectional key was arranged at portable electron device, its top was provided with the key cover plate, and the bottom is provided with circuit board.
Compared with prior art, advantage of the present utility model is: adopt this press-key structure, multidirectional key in use because key body is separate, can influence each other fully between the key body, thereby can prevent misoperation.And this kind multidirectional key structure need not adopt projection or pivot, and is simple in structure, easily manufactured.
