Abstract
The utility model relates to a structural design of a metal dome, in particular to a mobile communication terminal, a PDA, a PHS or an electric appliance remote controller which adopt metal dome key-presses. The top part arc surface of the novel metal dome is changed into a small platform. By adopting the press-key adopting the structure, under the identical metal dome travel during the pressing, the pressure of the press-key is increased, the hand feeling of the press-key is improved, and the reliability of the press-key is enhanced.
Description
Technical field
The utility model relates to the structural design of a kind of metal dome (metal clips), relates in particular to a kind of communication terminal that need to adopt metal dome button, PDA, Personal Handyphone System, electric appliance remote controller etc.
Background technology
Development along with mobile communication technology, the style of mobile communication terminal in the market is more and more abundanter, and the intelligent mobile communication terminal that wherein has qwerty keyboard (keyboard of naming according to the English alphabet arrangement mode on the keyboard) also more and more is subjected to liking of consumer.For satisfying consumer's operating handle, button must have enough strokes and actuating force, and therefore the metaldome of the keyboard of mobile communication terminal is a circular arc usually, as shown in Figure 1.The big more operating handle of the size of the vertex distance face of Metal dome can be good more; The big more operating handle of power that drives button rubber position (24 among Fig. 2) can be good more.Yet be subjected to the constraint of cell phone appearance design, the size of metal dome has the trend of further dwindling again.Under the situation of metal dome stroke limiting system, improve on the actuating force that is applied on the key and can satisfy the better operating handle of consumer.
The utility model content
At the characteristics of circular arc metal dome, in order to improve the button operation feel, the utility model proposes a kind of circular arc metal dome structure different from the past and make keyboard, the top arc shaped surface is become a chain-wales, as shown in Figure 2.The button that uses the metal dome of this structure to make can satisfy the requirement of consumer's feel, also can guarantee the button quality of mobile communication terminal simultaneously.

Embodiment
At the characteristics of circular arc metal dome, in order to improve the button operation feel, the utility model proposes a kind of circular arc metal dome structure different from the past and make keyboard, the top arc shaped surface is become a chain-wales, as shown in Figure 2.The button that uses the metal dome of this structure to make can satisfy the requirement of consumer's feel, also can guarantee the button quality of mobile communication terminal simultaneously.Structure is improved after the metaldome top is a chain-wales, after when driving keyboard, applying the situation of power F, because be that face (dome end face) is stressed with contacting of face (key_rubber face), on the tangent line of circular arc because angle be 90 the degree, force resolution is zero, thereby the assurance actuating force makes operating handle fine.
The dome structure that the utility model is mentioned can be applied to the following aspects:
(1) the metal dome as key zone is applied on the mobile communication terminal;
(2) the metal dome as key zone is applied to other digital devices and electric appliance remote controller etc.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (1)
1, the structural design of a kind of metal dome of new construction is characterized in that:
The top arc shaped surface becomes a chain-wales.
