Abstract

The present disclosure provides a housing assembly for an electronic device and an electronic device. The housing assembly includes a first housing, a second housing and a reinforcing column. The second housing and the first housing collectively define a receptacle, and at least a part of the reinforcing column is embedded in at least one of the first housing and the second housing. For the housing assembly according to the present disclosure, by embedding the reinforcing column in at least one of the first housing and the second housing, structural strength of the first housing or the second housing can be enhanced, and hence overall structural strength of the housing assembly can be enhanced, thereby improving bending resistance of the housing assembly and facilitating a lightweight and thin design of the electronic device.

First claim

What is claimed is:

1 . A housing assembly for an electronic device, comprising:
a first housing; a second housing, the second housing and the first housing collectively defining a receptacle capable of receiving a battery; and two reinforcing features, spaced apart from each other, each of the two reinforcing features having at least a part embedded in at least one of the first housing and the second housing, and axes of the two reinforcing features being flush with a central axis of the receptacle.

2 . The housing assembly according to claim 1 , wherein the two reinforcing features extend along a length direction or a width direction of the receptacle.

3 . The housing assembly according to claim 1 , wherein each of the two reinforcing features has a circular or polygonal cross section.

4 . The housing assembly according to claim 1 , wherein the first housing or the second housing, in which the two reinforcing features are embedded, is an injection molded part.

5 . The housing assembly according to claim 1 , wherein the first housing or the second housing is an aluminum-magnesium alloy piece or an aluminum alloy piece.

6 . The housing assembly according to claim 1 , wherein the two reinforcing features are stainless steel pieces.

7 . The housing assembly according to claim 1 , wherein hardness of the two reinforcing features is greater than hardness of the first housing or the second housing.

8 . The housing assembly according to claim 1 , wherein each of the two reinforcing features is a reinforcing column.

9 . The housing assembly according to claim 8 , wherein one of the reinforcing columns is close to a first end of the receptacle, and the other one of the reinforcing columns is close to a second end of the receptacle.

10 . An electronic device, comprising a housing assembly, a battery and a display unit, the housing assembly comprising a battery cover, a front cover and two reinforcing columns, the two reinforcing columns being arranged at two sides of the battery, axes of the two reinforcing columns being flush with a central axis of the battery, and the display unit being embedded in the housing assembly.

11 . The electronic device according to claim 10 , wherein each of the two reinforcing columns has a polygonal cross section.

12 . The electronic device according to claim 10 , wherein the battery cover and the front cover define a cavity, and the battery and the two reinforcing columns are arranged in the cavity.

13 . The electronic device according to claim 12 , wherein the two reinforcing columns are partially embedded in the front cover.

14 . The electronic device according to claim 10 , wherein the battery cover is made of aluminum-magnesium alloy.

15 . The electronic device according to claim 10 , wherein the display unit is embedded in a front face of the front cover.

16 . The electronic device according to claim 10 , wherein the front cover is an injection molded part, the two reinforcing columns are made of stainless steel bars, and hardness of the two reinforcing columns is greater than that of the front cover.

17 . A housing assembly for an electronic device, defining a receptacle and comprising two reinforcing columns, at least a part of each of the two reinforcing columns being embedded in the housing assembly and close to the receptacle, and axes of the two reinforcing columns being flush with a central axis of the receptacle.

18 . The housing assembly according to claim 17 , wherein the reinforcing column is partially exposed outside the housing assembly.

19 . The housing assembly according to claim 17 , wherein the reinforcing column is completely embedded in the housing assembly.

20 . The housing assembly according to claim 17 , wherein two reinforcing column are provided, one reinforcing column is located at a first side wall of the housing assembly while the other reinforcing column is located at a second side wall of the housing assembly opposite to the first side wall.
