Abstract

A hidden touch pad structure adopted for an electronic product is provided, which discloses a touch pad; a plate covering the touch pad, the plate having a pad-recognizing portion thereon corresponding to the touch pad; and a circuit board electronically connecting to the touch pad for receiving pressure signal when pressing the pad-recognizing portion of the plate.

Claims

1. A hidden touch pad structure adopted for an electronic product, comprising:

a touch pad;

a plate covering the touch pad, the plate comprising a pad-recognizing portion thereon corresponding to the touch pad; and

a circuit board electronically connecting to the touch pad for receiving pressure signal when pressing the pad-recognizing portion of the plate.

2. The hidden touch pad structure of claim 1, wherein the pad-recognizing portion is formed with printing different colors on the plate.

3. The hidden touch pad structure of claim 1, wherein the pad-recognizing portion is formed with a concave surface of the plate.

4. The hidden touch pad structure of claim 1, wherein the pad-recognizing portion is formed with a different surface on the plate.

5. The hidden touch pad structure of claim 1, wherein the pad-recognizing portion is formed with a surrounding wall on the plate.

6. The hidden touch pad structure of claim 1, wherein the plate exposes at least a clicking bottom, and the clicking bottom electronically connecting with the circuit board.

7. The hidden touch pad structure of claim 1, wherein the plate covers at least a clicking bottom, and the clicking bottom electronically connecting with the circuit board.

8. The hidden touch pad structure of claim 7, wherein the plate further comprises a click-recognizing portion for recognizing the clicking bottom.

9. The hidden touch pad structure of claim 8, wherein the click-recognizing portion is formed with printing different color on the plate.

10. The hidden touch pad structure of claim 8, wherein the click-recognizing portion is formed with a different surface on the plate.

11. The hidden touch pad structure of claim 1, wherein the plate has a various thickness.

12. The hidden touch pad structure of claim 11, wherein the plate comprises a recess concaved from a bottom surface thereof with a predetermined depth to form the various thickness thereof the recess is formed on the plate integrally in one piece, and the touch pad is disposed in the recess of the plate.

13. The hidden touch pad structure of claim 12, wherein the predetermined depth is substantially equal to a thickness of the touch pad.

14. The hidden touch pad structure of claim 12, wherein the touch pad has a top surface retained against an inner surface, being adjacent to the recess, of the plate.

15. The hidden touch pad structure of claim 1 further comprising a lighting device around the touch pad and received inside the plate;

whereby the circuit board receives the pressure signal, the circuit board further drives the lighting device to provide light, and the touch pad is recognized by the lighting device.

16. The hidden touch pad structure of claim 15, wherein the lighting device comprises a plurality of LEDs (Light Emitting Diodes).

17. The hidden touch pad structure of claim 16, further comprising a guiding member disposed between the plate and the LEDs, and the guiding member electronically connecting with the circuit board for obtaining uniformly light of the LEDs.

18. The hidden touch pad structure of claim 17, wherein the guiding member is a guide light strip.

19. A portable computer comprises the hidden touch pad structure of claim 1.
