Abstract

A touch pad module assembly structure includes a housing and a touch module. The housing includes a generally rectangular concave area, which includes a bottom surface, two housing edges, a step, a position pin and a convex member. The step is disposed closer to one of the two housing edges than the other thereof. The position pin is disposed on an inner surface of the one of the two housing edges. The convex member is disposed closer to the other of the two housing edges. The touch module includes a support member, which includes a position member and a hook member. The position member is disposed at an edge of the support member and includes a position hole to be engaged with the position pin. The hook member is disposed at an opposite edge of the support member and coupled with the other of the two housing edges.

Claims

1. A touch pad module assembly structure, comprising:

a housing comprising a generally rectangular concave area,

the concave area comprising;

a bottom surface;

a first housing edge and a second housing edge, respectively disposed at two opposite edges of the concave area;

a step disposed on the bottom surface and closer to the first housing edge than the second housing edge;

a position pin disposed on an inner surface of the first housing edge; and

a convex member disposed on the bottom surface and closer to the second housing edge than the first housing edge; and

a touch module comprising a support member,

the support member having two opposite edges as first and second support edges, comprising;

a position member disposed at the first support edge and comprising a position hole to be engaged with the position pin, the first support edge being in contact with the step of the concave area; and

a hook member disposed at the second support edge and coupled with the second housing edge.

2. The touch pad module assembly structure of claim 1, wherein the hook member comprises a generally triangular cross-section.

3. The touch pad module assembly structure of claim 1, wherein the touch module further comprises:

a circuit board disposed over the support member; and

a glass panel disposed over the circuit board.

4. The touch pad module assembly structure of claim 3, wherein the hook member comprises:

a first surface disposed generally in parallel with the glass panel;

a second surface disposed generally perpendicular to the first surface; and

a third surface interconnecting the first and second surfaces.

5. The touch pad module assembly structure of claim 4, wherein when the hook member is coupled with the second housing edge, an intersection of the second and third surfaces is in contact with the bottom surface of the concave area.

6. The touch pad module assembly structure of claim 4, wherein when the hook member is coupled with the second housing edge, the first surface is in contact with an inner surface of the second housing edge.

7. The touch pad module assembly structure of claim 1, wherein when the hook member is coupled with the second housing edge, a gap is formed between the support member and the bottom surface of the concave area.

8. The touch pad module assembly structure of claim 3, wherein when the hook member is coupled with the second housing edge, the circuit board comprises a switch to be in contact with the convex member of the concave area.

9. The touch pad module assembly structure of claim 8, wherein the support member has an opening, through which the switch is movable to contact the convex member of the concave area.

10. The touch pad module assembly structure of claim 1, wherein the support member is made from plastic materials.

11. The touch pad module assembly structure of claim 1, wherein the housing is made from metallic materials.

12. The touch pad module assembly structure of claim 8, wherein the support member is, when an edge of the touch pad module is pushed with the switch, bent to permit the switch to be pushed.

13. The touch pad module assembly structure of claim 8, wherein the support member recovers, when the switch releases from a state of pushing an edge of the touch pad, to an original position that is free of bends.

14. The touch pad module assembly structure of claim 1, wherein when the hook member is coupled with the second housing edge, the hook member is deformed and gradually engages with the second housing edge.
