Abstract

A touch panel assembly includes an enclosure, a touch panel, and a soft board. The enclosure includes a bottom portion. The bottom portion defines a first surface and a second surface. The enclosure further includes a first hook and a first positioning post extending from the first surface. The touch panel is attached on the second surface. The soft board defines a first securing hole and a first positioning hole. The first positioning post is received in the first positioning hole to prevent the soft board from moving along a first direction. The soft board is deformed by an external force to enable the first hook to pass through the first securing hole to engage with an edge of the first securing hole, thereby preventing the soft board from moving a second direction substantially perpendicular to the first direction.

Claims

1. A touch panel assembly comprising:

an enclosure, the enclosure comprises a bottom portion;

the bottom portion defines a first surface and a second surface; and

the enclosure further comprises a first hook and a first positioning post extending from the first surface;

a touch panel configured to be attached to the second surface; and

a soft board defines a first securing hole and a first positioning hole;

wherein the first positioning post is configured to be received in the first positioning hole to prevent the soft board from moving along a first direction; and

the soft board is configured to be deformed by external force to enable the first hook to pass through the first securing hole to engage with an edge of the first securing hole, thereby preventing the soft board from moving in a second direction substantially perpendicular to the first direction.

2. The touch panel assembly of claim 1, wherein the soft board comprises a board body, an extending portion extending from the board body and a resisting portion extending from the extending portion;

the resisting portion is configured to be deformed by external force to enable the first hook to pass through the first securing hole; and

a width of the extending portion is less than a width of the board body along a third direction substantially perpendicular to the second direction.

3. The touch panel assembly of claim 2, wherein the resisting portion is arc-shaped.

4. The touch panel assembly of claim 2, wherein the soft board further comprises a chip mounted on the board body, and the bottom portion defines an opening receiving the chip.

5. The touch panel assembly of claim 2, wherein the bottom portion defines a slot receiving the resisting portion, and the resisting portion passes through the slot to be electronically connected to the touch panel.

6. The touch panel assembly of claim 1, wherein the soft board further defines a second securing hole;

the enclosure further comprises a second hook extending from the first surface;

the second hook is configured to engage with an edge of the second securing hole to prevent the soft board from moving along the second direction.

7. The touch panel assembly of claim 1, wherein the first hook comprises a connecting portion extending from the first surface and an engaging portion extending from the connecting portion, and the engaging portion is substantially parallel to the bottom portion.

8. The touch panel assembly of claim 1, wherein the bottom portion is substantially parallel to the first direction and is substantially perpendicular to the second direction.

9. The touch panel assembly of claim 1, wherein the enclosure further comprises a second positioning post extending from the first surface;

the soft board further defines a second positioning hole configured to receive the second positioning post; and

the first hook is located between the first positioning post and the second positioning post.

10. A touch panel assembly comprising:

an enclosure, the enclosure comprises a bottom portion;

the bottom portion defines a first surface and a second surface;

the enclosure further comprises a first hook and a first positioning post extending from the first surface; and

the bottom portion defines a slot;

a touch panel, the touch panel is attached on the second surface; and

a soft board, the soft board comprises a board body, an extending portion extending from the board body, and a resisting portion extending from the extending portion;

the board body defines a first securing hole and a first positioning hole; and

the resisting portion is received in the slot to electronically contact the touch panel;

wherein the first positioning post is received in the first positioning hole to prevent the soft board from moving along a first direction;

the first hook engages with an edge of the first securing hole to prevent the soft board from moving a second direction substantially perpendicular to the first direction; and

the board body is driven by external force to be deformed to enable the first securing hole to disengage the first hook.

11. The touch panel assembly of claim 10, wherein a width of the extending portion is less than a width of board body along a third direction substantially perpendicular to the second direction.

12. The touch panel assembly of claim 10, wherein the resisting portion is arc-shaped.

13. The touch panel assembly of claim 10, wherein the soft board further comprises a chip mounted on the board body, and the bottom portion defines an opening receiving the chip.

14. The touch panel assembly of claim 10, wherein the soft board further defines a second securing hole;

the enclosure further comprises a second hook extending from the first surface;

the second hook engages with an edge of the second securing hole to prevent the soft board from moving along the second direction.

15. The touch panel assembly of claim 10, wherein the first hook comprises a connecting portion extending from the first surface and an engaging portion extending from the connecting portion, and the engaging portion is substantially parallel to the bottom portion.

16. The touch panel assembly of claim 10, wherein the bottom portion is substantially parallel to the first direction and is substantially perpendicular to the second direction.

17. The touch panel assembly of claim 10, wherein the enclosure further comprises a second positioning post extending from the first surface;

the soft board further defines a second positioning hole configured to receive the second positioning post; and

the first hook is located between the first positioning post and the second positioning post.
