摘要
An electronic device includes a front plate, a back plate that faces away from the front plate, a display, a frame, a polymer member, and an adhesive layer. The display is disposed between the front plate and the back plate and visible through the front plate. The frame surrounds an interior space between the front plate and the back plate and formed of a metallic material. The frame includes a first metal part and a second metal part. The polymer member is coupled to the frame and contains a polymer material. The adhesive layer bonds the polymer member and the frame. The frame includes an opening formed in a first part thereof. The opening is formed through the first metal part and being formed to a specified depth through the second metal part. The polymer member forms at least part of an inner surface of the opening.

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2020-0047045, filed on Apr. 17, 2020, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein its entirety.
The disclosure relates to an electronic device including a metal housing.
A housing of an electronic device may include a metal part formed of a metallic material and a polymer part coupled to the metal part. The metal part may include a first metal part, a second metal part, and contact surfaces by which the first metal part and the second metal part are coupled. The contact surfaces may include bumpy structures. The first metal part and the second metal part may be physically coupled through the bumpy structures.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
The first metal part and the second metal part may be physically coupled through the bumpy structures. The physical coupling cannot provide a sufficient coupling force. For example, in a process of manufacturing the housing, a clearance may be generated between the first metal part and the second metal part. The clearance may cause a defect in coloring.

What is claimed is:1. An electronic device comprising:a front plate; a back plate configured to face away from the front plate; a display disposed between the front plate and the back plate, the display being visible through the front plate; a frame configured to surround an interior space between the front plate and the back plate and formed of a metallic material, the frame including a first metal part containing a first metallic material and a second metal part containing a second metallic material; a polymer member coupled to the frame, the polymer member containing a polymer material; and an adhesive layer configured to bond the polymer member and the frame, wherein the frame includes an opening formed in a first part thereof, the opening being formed through the first metal part and being formed to a specified depth through the second metal part, and wherein the polymer member forms at least part of an inner surface of the opening. 2. The electronic device of claim 1 , wherein when viewed in a direction in which the opening is formed through the first metal part and the second metal part, a first metal area formed by the first metal part, a polymer area formed by the polymer member, and a second metal area formed by the second metal part are sequentially formed on the inner surface of the opening. 3. The electronic device of claim 1 , wherein the adhesive layer includes an organic adhesive layer containing an organic material. 4. The electronic device of claim 3 , wherein the adhesive layer includes a first adhesive layer coupled with the first metal part and a second adhesive layer coupled with the second metal part,wherein the first adhesive layer contains the first metallic material, the polymer material, and the organic material, and wherein the second adhesive layer contains the second metallic material, the polymer material, and the organic material. 5. The electronic device of claim 1 , wherein the opening extends along a lengthwise direction of the frame,wherein when viewed in an extension direction of the opening, the polymer member includes a first portion adjacent to a first end portion of the opening in the extension direction and a second portion adjacent to a second end portion of the opening in the extension direction, and wherein each of the first portion and the second portion forms a portion of the inner surface of the opening. 6. The electronic device of claim 5 , wherein the polymer member further includes a third portion extending from the first portion to the second portion along the inner surface of the opening. 7. The electronic device of claim 1 , wherein the opening is formed through at least part of the polymer member. 8. The electronic device of claim 1 , further comprising:a side button structure related to a function of the electronic device, wherein at least part of the side button structure is accommodated in the opening. 9. The electronic device of claim 5 , wherein the polymer member further includes a third portion configured to face the front plate or the back plate. 10. The electronic device of claim 1 , wherein the frame includes a first surface configured to face one of the front plate or the back plate and a second surface configured to face either the front plate or the back plate, andwherein the polymer member extends from one of the first surface towards to second surface or the second surface toward other first surface. 11. The electronic device of claim 10 , wherein at least part of the polymer member is accommodated in a recess formed on the first surface or the second surface, andwherein the opening is formed through the frame so as to be connected with the recess. 12. The electronic device of claim 1 , wherein a second part of the frame includes a first contact surface included in the first metal part and directly coupled with the second metal part and a second contact surface included in the second metal part and configured to make contact with the first contact surface, andwherein a bumpy structure including recesses in a repeated or irregular pattern is formed on each of the first contact surface and the second contact surface. 13.
