Description

Battery cover structure of electronic device

The present invention relates to a battery cover structure for an electronic device, and more particularly to a battery cover structure for a rotatably open electronic device.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) use batteries as their energy source. The portable electronic devices are mostly detachable batteries, which are housed in portable electronic devices, and are disposed on the body of the casing. Plug in the battery cover. When the battery is low and cannot be charged, or when the battery is damaged, open the battery cover and replace the battery.

The lock of the battery cover and the body of the electronic device is generally engaged with the card slot by a hook. As shown in FIG. 1, a slot 12' is defined in a body 10'. One end of the slot 12' defines an opening 14' which is wider than the slot 12'. A battery cover 20' has a hook 22'. The hook 22' has a column shape and has a rod portion 222' and a spherical end portion 224' formed at one end of the rod portion 222'. The end portion 224 'The diameter of the diameter is larger than the stem portion 222'. When the battery cover 20' is attached to the body 10', the end portion 224' of the hook 22' is first loaded from the opening 14' end, and then the battery cover 20' is pushed to slide the rod portion 222' of the hook 22' into In the card slot 12', the hook 22' is engaged with the card slot 12'. When the battery cover 20' is ejected, the battery cover 20' is pushed to slide the end portion 224' of the hook 22' to the opening 14' to disengage the hook 22' from the opening 14', so that the battery cover 20' is opened.

However, in the battery cover structure, after the battery cover 20' is opened, the battery cover 20' is completely separated from the body 10'. During this process, the removed battery cover 20' may be lost due to carelessness of the user, and the battery cover 20' When the battery cover structure is disassembled, the user needs to carefully align the hook 22' with the opening 14', which is inconvenient to use.

In view of the above, it is necessary to provide a battery cover structure that facilitates opening and closing of an electronic device.

The battery cover structure of an electronic device includes a battery cover, a body and a locking device. The battery cover is hinged at one end to the body, and the other end of the battery cover is equipped with the locking device, and the locking device is passed through the locking device. The device is movably locked to the body, the locking device includes a sliding body and an elastic member, the sliding body is slidably disposed in the battery cover, and the elastic member is disposed on the sliding body and the battery cover The elastic member abuts the sliding body to lock the sliding body with the body.

Compared with the prior art, the battery cover of the electronic device of the present invention is hinged to the body at one end, and the other end of the battery cover is locked with the body by a locking device, and when the battery cover is opened or closed, the sliding body is slid by an external force. The sliding body is locked or disengaged from the body to facilitate opening and closing of the battery cover of the electronic device.
