Abstract

An electronic device includes a main body, and a battery locking apparatus. The battery locking apparatus includes a locking unit, provided between a battery cover and the main body, which locks the battery cover to the main body; and an unlocking unit, provided between the locking unit and a battery, which provides a pushing force against the battery to unlock it from the main body.

Claims

1. An electronic device, comprising:

a main body;

a battery cover detachably coupled to the main body;

a battery disposed inside the battery cover; and

a battery locking apparatus, comprising;

a push button configured to be pressed towards the main body;

a cover locking unit, provided between the battery cover and the main body, which locks the battery cover to the main body and allows the battery cover to be unlocked when the push button is pressed; and

an unlocking unit, provided between the locking unit and the battery, which provides a pushing force against the battery to unlock it from the main body, wherein the unlocking unit comprises;

a first stopping jaw formed at the battery;

a second stopping jaw formed at the main body, and configured to be engaged with the first stopping jaw; and

a rod movably mounted to the main body in a horizontal direction, and configured to allow the first stopping jaw to be disengaged from the second stopping jaw when the push button is pressed.

2. The electronic device according to claim 1, wherein the main body comprises a battery mounting part which holds the battery and has a space which allows movement of the battery.

3. The electronic device according to claim 2, further comprising an elastic connection terminal which electronically connects the battery to the electronic device when the battery is mounted to the battery mounting part.

4. The electronic device according to claim 2, further comprising a withdrawal part that pushes the battery away from the battery mounting part.

5. The electronic device according to claim 4, wherein the withdrawal part comprises:

a push rod; and

an elastic member which biases the push rod towards the battery.

6. The electronic device according to claim 1, further comprising:

a first stopping member formed on the battery cover which catches with the push button.

7. The electronic device according to claim 6, wherein the push button comprises a first hook member which catches with the first stopping member.

8. The electronic device according to claim 6, further comprising an elastic member which biases the push button outwards from the electronic device.

9. The electronic device according to claim 6, wherein the push button comprises a cam member with a sloped face that pushes the rod when the push button is pressed.

10. The electronic device according to claim 6, further comprising an elastic member which returns the rod to an initial position when the push button is released.

11. The electronic device according to claim 6, wherein the cover locking unit comprises:

a second stopping member formed on an end of the battery; and

a second hook member formed on an inner side of the battery cover which engages with the second stopping member.

12. The electronic device according to claim 1, wherein the electronic device comprises a mobile terminal.

13. An electronic device, comprising:

a main body, comprising a battery mounting part that holds a battery;

a battery cover;

a push-button that releases the battery and the battery cover from the electronic device when it is pressed;

a first stopping jaw formed at the battery;

a second stopping jaw formed at the main body, and configured to be engaged with the first stopping jaw; and

a rod movably mounted to the main body in a horizontal direction, and configured to allow the first stopping jaw to be disengaged from the second stopping jaw when the push button is pressed.

14. The electronic device according to claim 13, wherein a first stopping member is formed at an upper end of the battery cover, and a first hook member, formed at a lower end of the push button, catches the first stopping member when the battery cover is pressed against the main body.
