Abstract

An electronic device including a first body, a second body, a pivoting shaft, a driving module, and a light source is provided. The first body includes a first casing and a second casing movably disposed on the first casing. The second body has a pivoting part and a light reflecting part located at the pivoting part. The pivoting shaft is connected to the pivoting part. The second body is pivoted to the first body through the pivoting shaft. The pivoting shaft, the driving module, and the light source are disposed in the first body. The driving module is connected to the pivoting shaft and contacts the second casing. When the second body rotates relative to the first body, the pivoting shaft drives the driving module to push the second casing to lift to form a light emitting slit between the second casing and the pivoting part.

First claim

What is claimed is:

1. An electronic device, comprising:
a first body, comprising a first casing and a second casing movably disposed on the first casing;
a second body, having a pivoting part and a light reflecting part located at the pivoting part;
a pivoting shaft, connected with the pivoting part of the second body, wherein the second body is pivoted to the first body through the pivoting shaft, and the pivoting shaft is located in the first body;
a driving module, disposed in the first body, and contacting the second casing, wherein the driving module is connected to the pivoting shaft; and
a light source, disposed in the first body,
wherein when the second body rotates relative to the first body, the pivoting shaft drives the driving module, the driving module pushes the second casing to lift to form a light emitting slit between the second casing and the pivoting part of the second body, and light emitted from the light source is directed to the light reflecting part through the light emitting slit.

2. The electronic device according to claim 1 , wherein the driving module comprises:
a first gear, connected to the pivoting shaft;
a second gear, engaged with the first gear;
a third gear, engaged with the second gear; and
a drive member, connected to a drive member of the third gear and contacting the second casing,
wherein when the second body rotates relative to the first body, the first gear rotates synchronously with the pivoting shaft, such that the first gear drives the second gear, the second gear drives the third gear, and the drive member rotates synchronously with the third gear and pushes the second casing to lift to form the light emitting slit between the second casing and the pivoting part of the second body.

3. The electronic device according to claim 2 , wherein the drive member is coaxially disposed with the third gear.

4. The electronic device according to claim 2 , wherein the first gear is coaxially disposed with the pivoting shaft.

5. The electronic device according to claim 2 , wherein the drive member has a drive part and a support convex arc part connected to the drive part, the drive part contacts the second casing to push the second casing to rotate and lift relative to the first casing, when the second body rotates relative to the first body to an angle greater than a predetermined angle, the drive part is separated from the second casing, and the support convex arc part contacts the second casing.

6. The electronic device according to claim 5 , wherein the second casing has a guide part facing the first casing and a buffer part connected to the guide part, the drive part slidingly contacts the guide part, when the second body rotates relative to the first body to an angle greater than the predetermined angle, the drive part is separated from the guide part, and the support convex arc part contacts the buffer part.

7. The electronic device according to claim 1 , wherein the light source is disposed on the second casing corresponding to the light emitting slit, the first casing has a reflect part disposed corresponding to the light source and the light emitting slit, and the light emitted from the light source is directed to the reflect part, and then is reflected by the reflect part to the light emitting slit, and is directed to the light reflecting part through the light emitting slit.

8. The electronic device according to claim 7 , wherein the light source is lifted with the second casing, and a distance between the light source and the reflect part is increased from a first distance to a second distance.

9. The electronic device according to claim 1 , wherein the light source is disposed on the first casing corresponding to the light emitting slit, and the light emitted from the light source is directed to the light emitting slit, and is directed to the light reflecting part through the light emitting slit.

10. The electronic device according to claim 1 , wherein the second body further has a display part connected to the pivoting part, there is a gap between a reflective surface of the light reflecting part and a display surface of the display part, and a part of the light reflecting part is located in the light emitting slit.

11. The electronic device according to claim 1 , wherein the first body further comprises a third casing mounted on the first casing, the second casing has a first end pivotally connected to the third casing and a second end opposite to the first end, and the driving module contacts the second end.

12. The electronic device according to claim 11 , wherein the second casing is located between the pivoting shaft and the third casing, when the second body rotates relative to the first body, the driving module pushes the second end of the second casing, such that the first end of the second casing rotates relative to the third casing, and the second end is lifted to form the light emitting slit with the pivoting part.
