Embodiment
Hereinafter with reference to relevant drawings, press-button structure of the present invention is described, wherein identical element is illustrated with identical reference marks, and for the ease of understanding, omission is not drawn by the element relevant to non-immediate of the present invention.
Please also refer to Fig. 2, Fig. 3 A, Fig. 3 B, Fig. 4 A and Fig. 4 B, Fig. 2 is the schematic perspective view of press-button structure of the present invention.Fig. 3 A is the schematic diagram of the panel of press-button structure of the present invention collocation electronic installation.Fig. 3 B is the schematic diagram after the panel sectional of press-button structure of the present invention and electronic installation.Fig. 4 A and Fig. 4 B is the generalized section of the panel of press-button structure of the present invention collocation electronic installation.Wherein, Fig. 4 B more illustrates as profile when press-button structure is not yet pressed with dotted line, with clear display pressing start that is rear and press-button structure before pressing and deformation situation.
A kind of press-button structure 2 of the present invention is arranged at the panel P of electronic installation, and electronic installation such as can be CD drive, and panel P is the outer panels of CD drive.And panel P can be arc surface panel or inclined-plane panel.
Press-button structure 2 of the present invention comprises press section 22, fixed part 24, at least one cantilever 26 and trigger unit 28.The present embodiment is for two cantilevers 26, and two cantilevers 26 be arranged in parallel.Press section 22 has the first side 22A and the second side 22B relative to the first side 22A.Distance between fixed part 24 and the second side 22B is less than the distance of fixed part 24 and the first side 22A, and fixed part 24 for peg button structure 2 in panel P.Its fixed form can be such as bolt, screw lock.
Each cantilever 26 connects the first side 22A and the fixed part 24 of press section 22, and in details of the words, one end of each cantilever 26 is connected with the first side 22A of press section 22, and the other end of cantilever 26 is then connected with fixed part 24.In brief, the contiguous second side 22B of fixed part 24, this side that fixed part 12 and cantilever 1 are arranged is non-conterminous.
When user presses press section 22, to make two cantilevers 26 produce a deformation (can with reference to figure 4B), the torque of press-button structure 2 during to absorb pressing, to improve the deflection produced when press-button structure 2 presses, and stress concentrates on the problem of fixed part 24.
Trigger unit 28 is arranged at the switch (scheme not shown) of press section 22 in order to triggerable electronic device, and trigger unit 28, can trigger switch (making circuit board conducting) after press section 22 is pressed, and electronic installation will receive enabling signal.Though drawing illustrates the first side 22A that trigger unit 28 is arranged at press section 22, enforcement aspect also can be had for being arranged at arbitrary cantilever 26.
Should be specified, cantilever 26 of the present invention is arranged at press section 22 relatively away from the first side 22A of fixed part 24, thus compare known press-button structure 1(can with reference to figure 1) the longer arm of force can be provided, comparatively laborsaving.
In addition, press section 22 of the present invention, cantilever 26, fixed part 24 and trigger unit 28 to be integrated into solid memder.And press-button structure 2 is made by flexible materials, and flexible materials such as can be plastic cement or rubber, but is not limited with these materials.
Cantilever 26 of the present invention also comprises the first cantilever portion 261 and the second cantilever portion 262, and the first cantilever portion 261 and the second cantilever portion 262 form the first angle β.And the second cantilever portion and horizontal line form one second angle α.Wherein, the illustrative first angle β of drawing is 90 °, and the second angle α is 30 °, and the cross section of each cantilever 26 about slightly rectangle, but be not limited with this angle, cross sectional shape and sectional area.
In details of the words, when user presses press section 22, the first cantilever portion 261 of cantilever 26 and the second cantilever portion 262 can be made to produce a deformation separately, and the deformation of the first cantilever portion 261 can offset the anticlockwise deflection in press section 22, the deformation of the second cantilever portion 262 then can offset the clockwise deflection in press section 22, therefore can realize making press section according to rectilinear motion by the first cantilever portion 261 and the second cantilever portion 262, and improve the shortcoming that reduction stress concentrates on fixed part 24.
Then, please also refer to Fig. 5, Fig. 6 be press-button structure of the present invention other two implement schematic diagrames.
Be with previous embodiment deviation: the cantilever 36 of the press-button structure 3 of two embodiments illustrated in drawing, except having the first cantilever portion 361, second cantilever portion 362, also comprises the 3rd cantilever portion 363.First cantilever portion 361 and the second cantilever portion 362 form the first angle β, and the 3rd cantilever portion 363 and the second cantilever portion 362 form one the 3rd angle theta.And Fig. 5 and Fig. 6 illustrates the execution mode that fixed part 34 is arranged at the diverse location of panel P respectively.
Similarly, when user presses press section 32, the first cantilever portion 361, second cantilever portion 362 of cantilever 36 can be made, the 3rd cantilever portion 363 produces deformation separately.And jointly offset clockwise and counterclockwise deflection by those cantilever portion, to realize making press section 32 according to rectilinear motion, and improve the shortcoming that reduction stress concentrates on fixed part 34.
For Fig. 5, the illustrative first angle β of drawing is 90 ° and the 3rd angle theta is 90 °, and the cross section of cantilever 36 is rectangle, but not as limit.And the illustrative first angle β of Fig. 6 is 90 ° and the 3rd angle theta is 120 °, the cross section about slightly rectangle of cantilever 36, but not as limit.
All the other other elements, interelement relation are all similar to previous embodiment, therefore will repeat no more.
In sum, press-button structure of the present invention is by being arranged at the first side of press section by cantilever, and fixed part and the second side comparatively vicinity, when press section is pressed, cantilever produces deformation to absorb torque, and improves known press-button structure and deflect and fall the problem of stress concentration.
The foregoing is only illustrative, but not be restricted.Anyly do not depart from spirit of the present invention and category, and to its equivalent modifications of carrying out or change, all should be contained in protection range that appending claims limits.
