Abstract

The utility model relates to an improved structure of a contact component for a rotary operation input device, which is mainly characterized in that an electricity conducting part on the upper edge of a contact component is partitioned to a plurality of parts of lateral electrodes which are mutually independent; moreover, the outer circumference of each lateral electrode is provided with tapered bulges arrayed radially; all tapered bulges are connected with each other by wider base parts and extend outwards with tapered tip parts. Therefore, when an operating disk bears stress and inclines above the contact component, lateral electrodes in different positions can be used for sensing the direction of operation. Furthermore, effective contact areas enlarging gradually inwards generated by the outer circumference of the tapered bulges can be used for forming voltage signals approaching to linear control for output.

Therefore, it is the revolution input device that is disclosed just like TOHKEMY 2004-86437 patent case, it touches assembly and associative operation mechanism just like Fig. 1, shown in Figure 1A, mainly be to be separated into four lateral electrodes 101 of independent sectorial area separately in the copper-foil conducting electricity that a circuit board 10 (touching assembly) is gone up circle, and be provided with the central contact electrode 102 of two concentric annular in these copper-foil conducting electricity central authorities, touch the operation board 2 that assembly 10 tops are provided with a conduction in this in addition, in this operation board 2 and touch assembly 10 between then be provided with an insulator (not drawing) so that this operation board 2 be able to and touch assembly 10 between keep a minor increment; During operation, because operation board 2 is pushed angle and strength has different distortion mode and deflection with different, as the 2nd, shown in the 2A figure, when with less strength pressing operation dish 2 edges, can make operation board 2 inclinations one low-angle, at this moment, 101 of the lateral electrodes that this operation board 2 can and touch assembly 10 have a less effective projected area 201, in this operation board 2, touch assembly 10 between pass to the electric charge of opposed polarity, can form the capacitance of a correspondence, and as the 3rd, shown in the 3A figure, when with big strength pressing operation dish 2 edges, can make operation board 2 wide-angles (distortion even) that tilt, this operation board 2 and touch assembly 10 between a bigger effective projected area 202 is arranged, relatively, it also has bigger capacitance, and pressing operation dish 2 central authorities, the conductive cap (not drawing) that then can oppress a convex arc shaped is out of shape, should central authorities' contact electrode 102 with conducting, form a basic construction of switch;

Utilize this kind principle,, also can learn operator's application of force size, form and further use form according to the size of this capacitance except determining to operate the direction of control according to the direction of operation board 2 stressed inclinations.

Yet, above-mentioned this kind structure itself because each lateral electrode 101 is to be one fan-shaped, cause its operation board 2 stressed inclinations and be not be directly proportional with its stressed size (shown in the 4th figure) in touching on the assembly 10 area that effectively touches that produces, therefore, when practical application, must just can meet demand with suitable soft, its nonlinear variation of hardware modifications in addition, the puzzlement that not only forms exploitation and use also produces distortion to a certain degree.

Summary of the invention

For overcoming deficiency of the prior art, the utility model provides a kind of assembly that touches that turns round input device to improve structure, it mainly is that the current-carrying part that will touch assembly (as circuit board) shape last week is divided into some five equilibriums lateral electrode independently separately, be provided with the awl protuberance that is radial arrangement in each lateral electrode outer peripheral edges, each bores protuberance is that base portion with broad is connected, and stretch out with the point of convergent, make an operation board when this touches the stressed deflection in assembly top, it is except that can the direction by the lateral electrode sense operation of diverse location, this operation board also can be under the stressed situation of difference, generation to the lateral electrode outer peripheral edges produce move closer to linear strengthen effectively touch area, form one with the strong and weak Linear Control voltage signal output of differentiating of pressure, to promote its range of application, this is a fundamental purpose of the present utility model.

The assembly that touches of this kind revolution input device of the present utility model improves structure, it is owing to can be the big or small voltage signal of the linear output of convergence with the application of force size in when operation, for direct application, and need not in addition with its curve of output of software program correction, except that can effectively reducing the cost of development, also help to reduce the distortion that is produced when revising, this is another purpose of the present utility model.

The technical solution adopted in the utility model is: each lateral electrode outer peripheral edges is provided with the awl protuberance that is radial arrangement, and each bores protuberance is that base portion with broad is connected, and stretches out with the narrow end of convergent.

The stretching, extension angle of described each lateral electrode is not more than 90 degree.

The copper-foil conducting electricity central authorities of described all shapes are provided with the central contact electrode of two concentric annular.
