Abstract
A portable electronic device includes a first body, a second body and a linkage. The first body has a first upper surface, and the second body has a second upper surface. An end of the linkage is coupled to the first body through a first pivot shaft and another end of the linkage is coupled to the second body through a second pivot shaft, in which the second body is suitable to be stacked on the first upper surface of the first body to make the portable electronic device in a retracted state. The linkage is suitable to rotate relatively to the first body so that the first body and the second body of the portable electronic device are side by side in an expanded state.
Claims18
A portable electronic device, comprising:
- a first body, having a first upper surface, a bottom surface opposite to the first upper surface, a first surface and a second surface both connecting between the first upper surface and the bottom surface, and the second surface opposite to the first surface;
- a second body, having a second upper surface;
- and
- a linkage, pivoted to the first body through a first pivot shaft and to the second body through a second pivot shaft, wherein the first pivot shaft and the second pivot shaft are substantially parallel to each other, and the second body is suitable to be stacked on the first upper surface of the first body to make the portable electronic device in a retracted state, and when the portable electronic device is in an expanded state, the second body and the first body are side by side, the second body is disposed adjacent to the second surface of the first body, and the first upper surface is substantially coplanar with the second upper surface, wherein
- when the portable electronic device is in the retracted state, an intersected point of the first surface of the first body and the bottom surface is taken as an original point, a direction extending from the original point towards the second surface along the bottom surface serves as X axis, a direction extending from the original point towards the first upper surface along the first surface serves as Y axis, coordinates of the first pivot shaft on X-Y plane are (XC1,YC1) and coordinates of the second pivot shaft on X-Y plane are (XC2,YC2), then:
- XC2=[(YC2−YC1)2+XC12−(W−XC1+δH)2]/[2(W+δH)];
- YC2=HU+YC1+δV;
- wherein W is a length of the first body on X axis direction;
- HB is a thickness of the first body on Y axis direction;
- HU is a thickness of the second body on Y axis direction;
- L is a distance between the first pivot shaft and the second pivot shaft on X-Y plane;
- δH is an interval between the first body and the second body on X axis direction when the portable electronic device is in the expanded state;
- and
- δV is an interval between the first body and the second body on Y axis direction when the portable electronic device is in the retracted state.
