Electronic device having detachable battery pack

1. An electronic device comprising:

a battery pack having a battery cell, a first support body, and a second support body, the first support body and the second support body provided at opposing ends of the battery cell, and the second support body including one or more seat protrusions protruding from one end of the second support body; and

a battery pack mount portion having an opening with a sheet plate disposed therein at a backside of the battery pack mount portion and one or more recesses arranged along one side of the battery pack mount portion that correspond to the one or more seat protrusions protruding from the second support body,

wherein the one or more seat protrusions of the second support body are seated within the one or more recesses of the battery pack mount portion when the battery pack is mounted to the battery pack mount portion, and

wherein concave recesses are formed on both a left side and a right side of the first support body of the battery, and wherein protrusions are formed in the battery pack mount portion, configured to fit in the concave recesses of the first support of the battery and protrude on corresponding positions of the battery pack mount portion.

2. The electronic device of claim 1 , wherein a plurality of the one or more seat protrusions comprise a plurality of seat protrusions that are arranged at a predetermined interval to an outer direction and protrude from one end of the battery pack.

3. The electronic device of claim 1 , wherein the one or more seat protrusions are formed to protrude in a rib shape from one end of the battery pack.

4. The electronic device of claim 1 , wherein the one or more seat protrusions are installed at a lower end of the battery pack, wherein the protrusions extend in lengthwise direction of the electronic device.

5. The electronic device of claim 1 , wherein the second support body is formed of an insulating synthetic resin.

6. The electronic device of claim 1 , wherein both a left and a right side of the battery pack mount portion form sidewalls around the opening in order to support both a left and a right of the battery pack.

7. The electronic device of claim 1 , wherein the sheet plate comprises one of a plastic sheet or a conductive tape minted with a case frame such that it is separable.

8. The electronic device of claim 1 , wherein the first support body is formed of an insulating synthetic resin.

9. The electronic device of claim 1 , wherein the battery pack mount portion includes a backside, and wherein the backside of the battery pack mount portion has a mount space formed under the backside of the electronic device.

10. The electronic device of claim 9 , wherein, when the battery pack is mounted in the battery pack mount portion, an upper side of the battery pack is provided under the backside of the electronic device.

11. The electronic device of claim 10 , wherein the one or more seat protrusions are configured not to protrude beyond the upper side of the battery pack or the backside of the electronic device when the one or more seat protrusions are seated in the one or more recesses.

12. The electronic device of claim 1 , wherein the battery pack mount portion further comprises a detachable cover, the detachable cover being coupled to the battery pack mount portion and forming at least a portion of the backside of the electronic device.

13. The electronic device of claim 1 , wherein the electronic device is a mobile terminal.

14. An electronic device comprising:

a case frame;

a battery pack having a battery cell, a first support body, and a second support body, the first support body and the second support body provided at opposing ends of the battery cell, and the second support body having one or more seat protrusions protruding from one end thereof; and

a battery pack mount portion formed in the case frame, the battery pack mount portion including an opening to receive the battery pack and a backside arranged therein and including one or more recesses that correspond to the one or more seat protrusions;

wherein the one or more seat protrusions of the second support body are seated within the one or more recesses of the battery pack mount portion when the battery pack is mounted on the battery pack mount portion, thus inhibiting to inhibit the battery pack from applying pressure to the backside arranged in the opening of the battery pack mount portion; and

wherein concave recesses are formed on both a left side and a right side of the first body of the battery, and wherein protrusions are formed in the battery pack mount portion, configured to fit in the concave recesses of the first support of the battery and protrude on corresponding positions of the battery pack mount portion.

15. The electronic device of claim 14 , wherein the backside comprises a sheet plate separating the backside of the battery pack mount portion from other components of the electronic device.

16. An electronic device, comprising:

a battery pack;

a case frame having an opening forming a battery pack mount portion in which the battery pack is mounted; and

a sheet plate blocking the opening at a backside of the battery pack mount portion;

wherein the battery pack comprises:

a battery cell; and

first and second support bodies supporting the battery cell on opposing ends of the battery cell;

wherein the first support body includes a recess;

wherein one or more seat protrusions protrude from the second support body to an outer direction;

wherein the battery pack mount portion comprises:

one or more seat recesses in which the one or more seat protrusions are seated;

a protrusion corresponding to the first support body recess; and

wherein when the battery pack is mounted the one or more seat protrusions are supported by the seat recesses, and the first support body recess is coupled to the corresponding protrusion.
