Description
Technical field
The utility model is meant a kind of volume that can significantly dwindle input media especially about a kind of roller structure of input media, and with portability and the power of keeping product, manual dexterity is comfortable simultaneously, can avoid a kind of roller structure of improper operation.
Background technology
Existing on the market at present many input medias with roller, for example common mouse or trace ball etc.The design of this roller only for convenience in the use of web browser, allows the user when viewing and admiring the big page originally, and intuitively the touch-control roller avoids traditional input media to click the inconvenience of control with the not intact picture that continues.Then be conceived to user's demand, roller devices is applied on the various software gradually, makes it become the indispensable important ring of modern input media.Again along with the prosperity of software, on input media, increase the mode of operating key quantity, become the trend in epoch, but because of being subject to the scope of finger activity space, input media must increase more function in the finite space, therefore roller has increased gradually again and has pressed the control function of pressing except original rolling function, and this is the control model of existing roller.
Yet along with development of times, the portability of input media has become the project that the user payes attention to.Carry the compact trend that become of input media for convenience.So, operational space significantly reduces in the input media, makes many functions and design effectively to include in.So in the input media on the market, emphasize powerful person, its volume is also huge relatively; And emphasize person easy to carry, its function is then limited greatly.Therefore, be necessary to improve again the deficiency of existing input media, the structure that has input media now reconfigured, and dwindled as far as possible, so can meet the design requirement of input media.
Traditional roller design as shown in Figure 1 and Figure 2, it includes a roller 11 in a scrambler 12, this scrambler 12 is used for understanding the rotation direction and the distance of roller 11, to export the cursor position on the specific signal decision screen.And this roller 11 connects scrambler 12 with an output shaft 13, makes its volume bigger, in any case the length of reduction output shaft 13, its spatial configuration is still greater than the width sum total of this roller 11 with scrambler 12.
And for example Fig. 3, Fig. 4 show a kind of old-fashioned optical encoding roller structure, it has a roller 21 and an optical encoder 22 structures, and different persons with Fig. 1, Fig. 2, be that its optical encoder 22 need not to connect the roller output shaft, and the graphic change on optical sensor roller 21 surfaces, use the activity pattern of differentiating this roller 21, and then understand the activity situation of this roller 21.Though the induction of these optical profile types need not the output shaft design, feasible for optical sensor, its optical encoder 22 still need be placed on outside the roller 21, causes its volume still huge, can't effectively dwindle the volume of input media.
In addition and since roller itself also have pressure by function, so feeling of stress touch-control system also is considerable design link.As 14 designs of the contact-making switch on Fig. 5 displayed map 1, the old-fashioned roller 11 of Fig. 2, this contact-making switch 14 is placed on roller output shaft 13 lower ends, and is excessive for avoiding volume, and traditional design is placed on this contact-making switch 14 other end of scrambler 12.So, when this input media is pressed by action, be fixed pivot with these scrambler 12 1 ends, this roller 11 is the point of application, stress point is then on contact-making switch 14.According to lever principle, this kind point of application is required great effort the most in the design of centre, causes pressure uncertain by work, often intensified pressure and increase the consume of part.And its pressure is a curved arc shape by direction with respect to application of force direction, and the thoughts and feelings when making its operation is nature more not, even causes the part application of force to scatter and disappear because of cross component force, so that will strengthen the application of force again, increases hand fatigue.
Figure 6 shows that the contact-making switch design of the optical encoding roller of Fig. 3, Fig. 4 for another example, because it is not to connect optical encoder 22 with hardware, so can on its roller 21 output shafts 23 1 ends, guide rails 25 be set, allow this roller output shaft 23 be limited in operation in the guide rails 25, and contact-making switch 24 is designed at output shaft 23 other ends.This method is compared to the design of Fig. 5, Fig. 6, and it there is no fixing fulcrum design, makes for the application of force major part of this roller 21 and all transfers on the contact-making switch 24, and this contact-making switch 24 is damaged easily.Simultaneously its guiding rule road 25 is too far away with distance of contact-making switch 24, is easy to generate bending moment, causes the improper damage with part of the application of force.
This shows that above-mentioned article commonly used still have many disappearances, real non-one kindhearted design, and demand urgently being improved.
Every shortcoming that the present utility model people derives in view of above-mentioned roller structure commonly used is urgently to think to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, and successfully the roller structure of the utility model input media is finished in research and development finally.
