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;

two housing edges respectively disposed at two opposite edges of the concave area;

a step disposed closer to one of the two housing edges than the other thereof;

a position pin disposed on an inner surface of the one of the two housing edges; and

a convex member disposed closer to the other of the two housing edges; and

a touch module comprising a support member, the support member comprising

a position member disposed at an edge of the support member and comprising a position hole to be engaged with the position pin; and

a hook member disposed at an opposite edge of the support member and coupled with the other of the two housing edges.

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 2, 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 surface.

5. The touch pad module assembly structure of claim 4, wherein when the hook member is coupled with the other of the two housing edges, an intersection of the second and third surface 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 other of the two housing edges, the first surface is in contact with an inner surface of the other of the two housing edges.

7. The touch pad module assembly structure of claim 1, wherein when the hook member is coupled with the other of the two housing edges, 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 1, wherein when the hook member is coupled with the other of the two housing edges, 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 comprises an opening to be inserted through by the switch to contact the convex member of the concave area.

10. The touch pad module assembly structure of claim 1, wherein the edge of the support member is in contact with the step of the concave area.

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

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