Electronic device having detachable battery

An electronic device includes a first cover, a double sided pressure sensitive adhesive (PSA) tape, a battery, and a second cover. The second cover is attached to the first cover. The battery is arranged between the first cover and the second cover. The second cover defines a groove. A shape of the groove is substantially same as a shape of the PSA tape. The PSA tape covers the groove. Thereby the PSA tape and the groove cooperatively form an air flowing channel having an inlet and an outlet. The battery is fixed to the second cover by the PSA tape. An adhesive force of the PSA tape applied between the battery and the second cover is decreasable by flowing air with temperature greater than a preset value through the air flowing channel so as to enable the battery to detach from the second cover.

BACKGROUND

1. Technical Field

The present disclosure relates to electronic devices, and particularly to an electronic device having a detachable battery.

2. Description of Related Art

The batteries of electronic devices such as cell phones are often stuck in the electronic device using adhesive tape. However, if the battery needs to be removed for maintenance, the battery needs to be removed from the electronic device. The battery may be damaged because the strong adhesive of the adhesive tape. Therefore, an electronic device having detachable battery is needed to resolve the above problem.

DETAILED DESCRIPTION

The embodiments of the present disclosure are described with reference to the accompanying drawings.

Referring toFIGS. 1-2, an electronic device1is shown in accordance with an exemplary embodiment. The electronic device1includes a first cover10, a double sided pressure sensitive adhesive (PSA) tape2, a battery20, and a second cover30. The first cover10is coupled to the second cover30. The first cover10and the second cover30cooperatively define a receiving space (not label). The battery20is received in the receiving space. The battery20is fixed to the second cover30using the PSA tape2. The stickiness of the PSA tape2increases as the temperature of the PSA tape2increases when the temperature of the PSA tape2is less than a preset value, and decreases as the temperature of the PSA tape2increases when the temperature of the PSA tape2is greater than the preset value.

Referring toFIGS. 3-4, the second cover30defines a number of slots311. The slots311are arranged to form a groove31. In the embodiment, the groove31includes three slots311in parallel and one slot311at each end of the parallel slots311to form a bisected rectangle. A length of the groove31formed by the slots311is less than or equal to a length of the battery20, and a width of the groove31formed by the slots311is less than or equal to a width of the battery20. A shape of the PSA tape2is substantially same as a shape of the groove31. The PSA tape2includes a number of sides21corresponding to the slots311. A width of each side21of the PSA tape2is greater than a width of the corresponding slot311of the groove31, and a length of each side21of the PSA tape2is equal to a length of the corresponding slot311of the groove31. Thus, when the PSA tape2is stuck to the groove31of the second cover30, the PSA tape2completely covers the groove31, and the PSA tape2and the groove31cooperatively form an air flowing channel having an inlet32and an outlet33.

To remove the battery20from the second cover30, air with a temperature greater than the preset value needs to be injected into the groove31from the inlet32. The injected air flows along the air flowing channel and exits from the outlet33, and heats the PSA tape2covering the groove31. Thus the adhesive force of the PSA tape2applied between the battery20and the second cover30is descreasable so as to enable the battery20to detach from the second cover30.

In an alternative embodiment, the shape of the groove31can be varied according to need. Then the shape of the PSA tape2is changed to correspond to the shape of the groove31.
