Abstract

An electronic device includes a middle frame, a first flexible printed circuit FPC, a second FPC and a battery. Projections of the first FPC and the second FPC on the middle frame have a first overlapping region. The first overlapping region is located inside a projection of the battery on the middle frame and is far away from an edge of the battery. A first through hole is disposed on the middle frame. The first overlapping region is located in the first through hole. The electronic device provided in this application can implement reduction of an overall thickness, so that the electronic device provides better user experience.

First claim

What is claimed is:

1. An electronic device, comprising:
a middle frame having a first through hole;
a first flexible printed circuit (FPC);
a second FPC; and
a battery;
wherein a first groove and a second groove are respectively disposed on two side surfaces of the middle frame, wherein the first FPC is disposed in the first groove, and the second FPC is disposed in the second groove, wherein projections of the first FPC and the second FPC on the middle frame have a first overlapping region, wherein the first overlapping region is located inside a projection of the battery on the middle frame and is far away from an edge of the battery, and wherein the first overlapping region is located in the first through hole.

2. The electronic device according to claim 1 , wherein an avoidance hole is disposed on the first FPC, and wherein the first FPC avoids the second FPC by the avoidance hole, so that the first overlapping region is far away from the edge of the battery.

3. The electronic device according to claim 2 , wherein the first FPC and the second FPC are respectively disposed on two opposite sides of the middle frame.

4. The electronic device according to claim 3 , wherein the middle frame comprises a protrusion part, wherein a front end of the protrusion part extends into the avoidance hole, and wherein a rear end of the protrusion part forms avoidance space accommodating the second FPC.

5. The electronic device according to claim 1 , wherein the projections of the first FPC and the second FPC on the middle frame have a second overlapping region, wherein the first FPC further comprises a thinning region, wherein a thickness of the thinning region is less than a thickness of another region of the first FPC, and a projection of the thinning region on the middle frame covers the second overlapping region.

6. The electronic device according to claim 5 , wherein the first overlapping region is connected to the second overlapping region.

7. The electronic device according to claim 5 , wherein the first FPC comprises an FPC body and a functional film layer that are stacked, and wherein the FPC body and the functional film layer are thinned to form the thinning region.

8. The electronic device according to claim 7 , wherein the functional film layer comprises a protective film layer and a shielding film layer.

9. The electronic device according to claim 5 , wherein the first FPC comprises an FPC body and a functional film layer that are stacked, and wherein the FPC body is thinned to form the thinning region.

10. The electronic device according to claim 5 , wherein the first FPC comprises an FPC body and a functional film layer that are stacked, and wherein the functional film layer is thinned to form the thinning region.

11. The electronic device according to claim 1 , wherein the first FPC is a screen FPC of the electronic device, and the second FPC is a main FPC of the electronic device.

12. The electronic device according to claim 11 , wherein the first FPC is fixedly attached to an inner surface of a display of the electronic device by a first back adhesive layer, and the second FPC is fixedly attached to the middle frame by a second back adhesive layer.

13. The electronic device according to claim 12 , wherein a third groove is further disposed on the middle frame in the second groove, and wherein the second back adhesive layer is disposed in the third groove.

14. The electronic device according to claim 11 , wherein the first FPC passes through a second through hole and is electrically connected to a main board of the electronic device, wherein the second through hole is disposed on the middle frame.

15. The electronic device according to claim 1 , wherein the first FPC and the second FPC are located on two opposite sides of the middle frame.

16. The electronic device according to claim 1 , wherein contours of the first through hole and the first overlapping region overlap.

17. An electronic device, comprising:
a main board;
a middle frame having a first through hole and a second through hole;
a first flexible printed circuit (FPC) passing through the second through hole and being electrically connected to a main board;
a second FPC; and
a battery;
wherein a first groove and a second groove are respectively disposed on two side surfaces of the middle frame, wherein the first FPC is disposed in the first groove, and the second FPC is disposed in the second groove, wherein projections of the first FPC and the second FPC on the middle frame have a first overlapping region, wherein the first overlapping region is located inside a projection of the battery on the middle frame and is far away from an edge of the battery, and wherein the first overlapping region is located in the first through hole.

18. The electronic device according to claim 17 , wherein an avoidance hole is disposed on the first FPC, and wherein the first FPC avoids the second FPC by the avoidance hole, so that the first overlapping region is far away from the edge of the battery.

19. The electronic device according to claim 17 , wherein the first FPC is a screen FPC of the electronic device, and the second FPC is a main FPC of the electronic device.
