Abstract

A pressing-type pad structure and an electronic device using the same are provided. The pressing-type pad structure includes a pad component, an elastic element and a positioning element. The rotatable pad component is disposed on a housing of the electronic device and has at least two concave portions. The elastic element connects the housing and the pad component. The positioning element is elastically disposed on the housing. One end of the positioning element is leant against the pad component. When the electronic device is pressed or moved, an elastic force of the elastic element is applied to the pad component to drive the pad component to rotate. The positioning element is selectively inserted into one of the concave portions for fixing the pad component, so as to change the position of the electronic device.

Claims

1. A pressing-type pad structure for being disposed on a housing of an electronic device, the pressing-type structure comprising:

a rotatable pad component disposed on the housing and having at least two concave portions;

an elastic element connecting the housing and the pad component; and

a positioning element elastically disposed on the housing, one end of the positioning element leant against the pad component;

wherein an elastic force of the elastic element is applied to the pad component and drives the pad component to rotate when the electronic device is pressed or moved, the positioning element is selectively inserted in one of the two concave portions for fixing the pad component so as to change the position of the electronic device.

2. The pad structure according to claim 1, wherein the pad component comprises a cam.

3. The pad structure according to claim 2, wherein the pad component further comprises a soft pad covering the cam.

4. The pad structure according to claim 1, wherein the distances from the concave portions to an axle of the pad component are substantially the same.

5. The pad structure according to claim 1, wherein the two concave portions are two positioning holes.

6. The pad structure according to claim 1, wherein the positioning element comprises a positioning pin and another elastic element connected with the positioning pin and disposed on the housing, the positioning pin is able to be inserted into one of the concave portions of the pad component for fixing the pad component.

7. The pad structure according to claim 1, wherein the elastic element is a torsion spring, one end of the torsion spring is connected with the housing, and the other end of the torsion spring is connected with pad component.

8. The pad structure according to claim 7, wherein the pad component comprises an axle for connecting with the housing, the torsion spring surrounds the axle.

9. An electronic device comprising:

a housing; and

at least two pressing-type pad structures disposed on the bottom of the housing, each pressing-type pad structure comprising;

a rotatable pad component disposed on the housing and having at least two concave portions;

an elastic element connecting the housing and the pad component; and

a positioning element elastically disposed on the housing, one end of the positioning element leant against the pad component;

wherein an elastic force of the elastic element is applied to the pad component and drives the pad component to rotate when the housing is pressed or moved, the positioning element selectively inserted into one of the concave portions for fixing the pad component so as to change the position of the housing.

10. The electronic device according to claim 9, wherein the pad component comprises a cam.

11. The electronic device according to claim 10, wherein the pad component further comprises a soft pad covering the cam.

12. The electronic device according to claim 9, wherein the distances from the concave portions to an axle of the pad component are substantially the same.

13. The electronic device according to claim 9, wherein the concave portions are positioning holes.

14. The electronic device according to claim 9, wherein the positioning element comprises a positioning pin and another elastic element connected with the positioning pin and disposed on the housing, the positioning pin able to be inserted into one of the concave portions for fixing the pad component.

15. The electronic device according to claim 9, wherein the elastic element is a torsion spring, one end of the torsion spring is connected with the housing, and the other end of the torsion spring is connected with the pad component.

16. The electronic device according to claim 15, wherein the pad component comprises an axle for connecting with the housing, the torsion spring surrounds the axle.
