Abstract

A fixing sheet adapted for fixing a battery to a body of an electronic apparatus is provided. The fixing sheet includes a structure layer having a first portion, a second portion and a split line. The first portion is adapted to be adhered to the battery. The second portion is structurally connected to the first portion and adapted to be adhered to the body. The split line is located at a common border of the first portion and the second portion. The first portion is capable of being forced relative to the second portion once the battery is forced relative to the body, so as to separate the first portion and the second portion along the split line. An electronic apparatus having the fixing sheet is also provided.

Claims

1. A fixing sheet, adapted for fixing a battery to a body of an electronic apparatus, the fixing sheet comprises:

a structure layer having a first surface and a second surface opposite to the first surface, wherein the structure layer comprises a first portion, a second portion and a weak portion having weaker structural strength than the first portion and the second portion, the second portion is structurally connected to the first portion through the weak portion, the first portion, the second portion and the weak portion share the first surface, and the first portion, the second portion and the weak portion share the second surface;

a first adhesive layer disposed on the first surface of the first portion and not on the first surface of the second portion; and

a second adhesive layer disposed on the second surface of the second portion and not on the second surface of the first portion.

2. The fixing sheet of claim 1, wherein the weak portion comprises a plurality of slits successively arranged in series with a fixed interval.

3. The fixing sheet of claim 2, wherein the plurality of slits are arranged in a straight line.

4. The fixing sheet of claim 1, wherein the structure layer comprises a metal thin film, a polyethylene terephthalate film or a paper.

5. The fixing sheet of claim 1, wherein the structure layer is a copper foil.

6. The fixing sheet of claim 1, wherein the structure layer is capable of conducting heat generated by the battery to the body.

7. An electronic apparatus, comprising:

a body;

a battery disposed within the body; and

a fixing sheet disposed between the body and the battery, the fixing sheet comprises;

a structure layer having a first surface and a second surface opposite to the first surface, wherein the structure layer comprises a first portion, a second portion and a weak portion having weaker structural strength than the first portion and the second portion, the second portion is structurally connected to the first portion through the weak portion, the first portion, the second portion and the weak portion share the first surface, and the first portion, the second portion and the weak portion share the second surface;

a first adhesive layer disposed on the first surface of the first portion and not on the first surface of the second portion; and

a second adhesive layer disposed on the second surface of the second portion and not on the second surface of the first portion.

8. The electronic apparatus of claim 7, wherein the weak portion comprises a plurality of slits successively arranged in series with a fixed interval.

9. The electronic apparatus of claim 8, wherein the plurality of slits are arranged in a straight line.

10. The electronic apparatus of claim 7, wherein the structure layer comprises a metal thin film, a polyethylene terephthalate film or a paper.

11. The fixing sheet of claim 7, wherein the structure layer is a copper foil.

12. The fixing sheet of claim 7, wherein the structure layer is capable of conducing heat generated by the battery to the body.
