Generalized section.Wherein, Fig. 4 B are more schematically shown as profile when press-button structure is not yet pressed with dotted line, with clearly show that pressing after
With the start of press-button structure and deformation situation before pressing.
A kind of press-button structure 2 of the present invention is arranged at the panel P of electronic installation, and electronic installation for example can be disc drives
Device, and panel P is the outer panels of CD drive.And panel P can be arc surface panel or inclined-plane panel.
The press-button structure 2 of the present invention includes press section 22, at least fixed part 24, a cantilever 26 and trigger unit 28.This reality
Example is applied by taking two cantilevers 26 as an example, and two cantilevers 26 be arranged in parallel.Press section 22 has the first side 22A and relative to the first side
The second side 22B of 22A.Distances of the distance between the side 22B of fixed part 24 and second less than the side 22A of fixed part 24 and first, and
Fixed part 24 is used for peg button structure 2 in panel P.Its fixed form may be, for example, bolt, screw lock.
First side 22A and the fixed part 24 of the connection of each cantilever 26 press section 22, in details of the words, one end of each cantilever 26 with press
First side 22A of splenium 22 is connected, and the other end of cantilever 26 is then connected with fixed part 24.In short, fixed part 24 is neighbouring
Second side 22B, side that fixed part 12 is arranged with cantilever 1 is non-conterminous.
When user presses press section 22, so that two cantilevers 26 produce a deformation（Refer to Fig. 4 B）, to absorb pressing
When press-button structure 2 torque, to improve the deflection that produces when press-button structure 2 is pressed, and stress concentration is in the problem of fixed part 24.
Trigger unit 28 is then arranged at press section 22 to trigger a switch of electronic installation（It is not shown）, trigger unit 28 exists
After press section 22 is pressed, switch is can trigger（Turn on circuit board）, electronic installation will receive enabling signal.Though drawing is illustrated
Trigger unit 28 is arranged at the first side 22A of press section 22, but can also have enforcement aspect to be arranged at arbitrary cantilever 26.
Should be specified, the cantilever 26 of the present invention is arranged at the first side that press section 22 is relatively distant from fixed part 24
22A, therefore compare known press-button structure 1（Refer to Fig. 1）The longer arm of force can be provided, it is more laborsaving.
Additionally, the press section 22 of the present invention, cantilever 26, fixed part 24 and trigger unit 28 can be to be integrated into single structure
Part.And press-button structure 2 is made by flexible materials, and flexible materials can be for example plastic cement or rubber, but not with these materials
Matter is limited.
The cantilever 26 of the present invention also includes the first cantilever portion 261 and the second cantilever portion 262, and the first cantilever portion 261 with
Second cantilever portion 262 forms the first angle β.And second cantilever portion and horizontal line form one second angle α.Wherein, drawing is illustrated
The first angle β be 90 °, and the second angle α is 30 °, and the section of each cantilever 26 about slightly rectangle, but not at this angle, cut
Face shape and sectional area are limited.
In details of the words, when user presses press section 22, first cantilever portion 261 and the second cantilever of cantilever 26 can be made
Portion 262 each produces a deformation, and the deformation of the first cantilever portion 261 can offset the anticlockwise deflection in press section 22, and second
The deformation of cantilever portion 262 can then offset the clockwise deflection in press section 22, therefore outstanding by the first cantilever portion 261 and second
Arm 262 is capable of achieving to make press section according to linear motion, and improves reduction stress concentration in the shortcoming of fixed part 24.
Then, schematic diagram is implemented please also refer to other the two of the press-button structure that Fig. 5, Fig. 6 are the present invention.
It is with previous embodiment deviation：The cantilever 36 of the press-button structure 3 of two embodiments illustrated in drawing except
Outside with the first cantilever portion 361, the second cantilever portion 362, also including the 3rd cantilever portion 363.First cantilever portion 361 and the second cantilever
Portion 362 forms 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 is then
It is to illustrate the embodiment 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 of cantilever 36 can be made
362nd, the 3rd cantilever portion 363 each produces deformation.And deflection clockwise and counterclockwise is offset jointly by those cantilever portions, with
Realization makes press section 32 according to linear motion, and improves reduction stress concentration in the shortcoming of fixed part 34.
By taking Fig. 5 as an example, the first angle β that drawing is illustrated is 90 ° and the 3rd angle theta is 90 °, and the section of cantilever 36 is square
Shape, but be not limited.And it is 120 ° that the first angle β that Fig. 6 is illustrated is 90 ° and the 3rd angle theta, the section of cantilever 36 is rough
For rectangle, but it is not limited.
Remaining other elements, interelement relation are all similar to previous embodiment, therefore will not be described in great detail.
In sum, press-button structure of the invention is by the way that cantilever to be arranged at the first side of press section, and fixed part and the
Two sides are more neighbouring, and when press section is pressed, cantilever produces deformation to absorb torque, and improves known press-button structure deflection and drop
The problem of stress concentration.
The foregoing is only illustrative, rather than for restricted.Any spirit and scope without departing from the present invention, and it is entered
Capable equivalent modifications or change, are intended to be limited solely by the protection domain that appending claims is limited.
