Detailed Description
The present invention will be described in further detail with reference to specific examples.
The embodiment is as follows:
as shown in fig. 1 to 3, the utility model discloses a fingerprint identification power button, by the push switch 5 of supreme laminating in proper order down, flexible circuit board 3, base 1, light guide block 2, fingerprint chip 6 and apron 4, light guide block 2 has the bellied side wall 22 that makes progress, side wall 22 encloses into one and is used for acceping push switch 5 and fingerprint chip 6 heavy platform 21, be equipped with the perforation 211 that supplies flexible circuit board 3's end to pass on heavy platform 21, it has the luminous component 7 that is used for showing different chromatic lights according to power status to accomodate in the perforation 211, flexible circuit board 3 electricity is connected in push switch 5, luminous component 7 and fingerprint chip 6. The light emitting part 7 emits light to the periphery inside the power key and can adopt an LED lamp. The push switch 5 is mechanically pushed to be turned on. After pressing apron 4, base 1 can move down, makes push switch 5 switch on circuit, and the signal of telecommunication just can be followed flexible circuit board 3 and transmitted the treater this moment, then shows corresponding suggestion colour through luminous component 7. Since the light emitting part 7 is located at the through hole 211 in the light guide block 2, the light will enter the light guide block 2 and will be scattered and then emerge from the side wall 22, which is a ring-shaped color light surrounding the cover plate 4. In order to allow a user to sense a fingerprint by the fingerprint chip 6 when pressing the cover plate 4, the thickness of the cover plate 4 is only 0.1-0.2mm. This power button can utilize fingerprint chip 6 to carry out fingerprint identification when pressing, also can utilize push switch 5 to realize the switch of power, can also utilize luminous component 7 to show the power state. The method comprises the following specific steps: according to press the switch 5 start-up after luminous component 7 can show a kind of chromatic light (like white), luminous component 7 can show second kind of chromatic light (like green) when 6 fingerprint unblocks of fingerprint chip are successful, luminous component 7 can show second kind of chromatic light (like orange) when 6 fingerprint unblocks of fingerprint chip fail, just so can show the different states of power. The power supply key integrates the functions of a power switch, fingerprint identification and state display, more functions are given in the effective space of the power supply key, redundant keys on a keyboard are reduced, and the attractiveness is improved.
As shown in fig. 3. The upper surface of the sidewall 22 faces the cover plate 4, and the cover plate 4 is transparent in the area close to the sidewall 22. Some slits are left between the cover plate 4 and the side wall 22 to complete the press start without allowing dust to easily enter the sinking platform 21. The area of the cover plate 4 close to the side wall 22 is edge-transparent, and the color can be seen through.
As shown in fig. 2, an enclosing part 11 surrounding the light guide block 2 is convexly arranged on the upper surface of the base 1, and a clearance groove 12 for the flexible circuit board 3 to horizontally penetrate through is arranged on the enclosing part 11. The surrounding portion 11 can surround and limit the light guide block 2. The flexible circuit board 3 is actually led out from the gap between the base 1 and the light guide block 2, and in order to prevent the flexible circuit board 3 from being bent, the surrounding portion 11 is provided with a clearance groove 12 as a passage through which the flexible circuit board 3 passes.
As shown in fig. 2, the through hole 211 is an elongated structure through which the flexible circuit board 3 can pass, the outer side of the sidewall 22 is provided with a protrusion 221, and the surrounding portion 11 is provided with a notch 111 for positioning the angle of the light guide block 2 in cooperation with the protrusion 221. The flexible circuit board 3 is a J-shaped bent strip-shaped component, and passes through the slender through hole 211 and also passes through the avoiding groove 12, so that the angle between the base 1 and the light guide block 2 can be positioned by the protrusion 221 and the notch 111, and the flexible circuit board 3 cannot be extruded due to relative rotation of the two after being installed, thereby avoiding circuit damage.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
