Abstract

A hidden touch pad structure adopted for an electronic product has a plate, a touch pad arranged inside the plate, a circuit board disposed under and retained against the plate and the touch pad simultaneously, and a lighting device surrounding the touch pad and received inside the plate. The circuit board receives a pressure signal via the plate and the touch pad, and drives the lighting device to provide light. The touch pad is recognized via the lighting device surrounding thereof.

Claims

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

a plate;

a touch pad arranged inside the plate;

a circuit board disposed under and retained against the plate and the touch pad, simultaneously;

wherein the touch pad electrically connects to the circuit board, whereby the circuit board receives a pressure signal via the plate and the touch pad.

2. The hidden touch pad structure as claimed in claim 1, wherein the plate has a various thickness.

3. The hidden touch pad structure as claimed in claim 2, wherein the plate includes a recess concaved from a bottom surface thereof with a predetermined depth to make 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.

4. The hidden touch pad structure as claimed in claim 3, wherein the predetermined depth approaches a thickness of the touch pad.

5. The hidden touch pad structure as claimed in claim 3, wherein the touch pad has a top surface retained against an inner surface, being adjacent to the recess, of the plate.

6. The hidden touch pad structure as claimed in claim 1 further comprising a lighting device surrounding the touch pad and received inside the plate, when the circuit board receives the pressure signal via the plate and the touch pad, the circuit board further drives the lighting device to provide light, and the touch pad is recognized via the lighting device surrounding thereof.

7. The hidden touch pad structure as claimed in claim 6, wherein the lighting device includes a surrounding plurality of LEDs (Light Emitting Diode).

8. The hidden touch pad structure as claimed in claim 6, wherein the lighting device includes a lighting member and a guiding member connecting sequentially.

9. The hidden touch pad structure as claimed in claim 8, wherein the lighting member is an LED (Light Emitting Diode).

10. The hidden touch pad structure as claimed in claim 8, wherein the guiding member is a guide light strip.
