Battery cover structure

The present invention relates to a battery cover structure, and more particularly to a battery cover structure applied to a portable electronic device.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used. These portable electronic devices use batteries as a source of energy. The battery of the portable electronic device is mostly a detachable battery, and is housed in a portable electronic device, and a battery cover that is inserted into the body of the casing is disposed on the battery. When the battery is low and cannot be powered or the battery is damaged, open the battery cover and replace the battery. Therefore, many battery cover structures have been designed in order to replace the battery easily and reliably.

A conventional battery cover structure includes a body, a battery cover, a button and a spring, the button is slidably mounted on the body, the spring is abutted between the button and the body, and the button is provided with a protrusion and a battery cover A groove is provided thereon, and the protrusion and the groove cooperate to engage the battery cover to the body. When the battery cover needs to be removed, a force parallel to the surface of the body and away from the battery cover is applied to the button, so that the button moves horizontally, and the protrusion is released from the groove of the battery cover, and the buckle of the battery cover is released. The battery cover structure has a complicated structure and is inconvenient to operate. In addition, the direction in which the spring is contracted is the same as the direction in which the button moves, which tends to loosen the engagement of the button with the battery cover, causing the battery cover to be stuck tightly.

In view of the above, it is necessary to provide a battery cover structure that is simple in structure, convenient in operation, and securely fastened.

A battery cover structure includes a body and a cover, the body includes a battery receiving groove, and the battery receiving groove includes two wall portions disposed in parallel; the cover is detachably mounted on the body a battery receiving groove; at least one protruding post is respectively protruded from the outer surface of the wall of the battery receiving groove; the cover body has a matching with the two wall portions of the receiving groove The inner side surfaces of the two side walls are respectively provided with elastic engaging portions that cooperate with the protruding posts, and the protruding posts and the engaging portions are elastically cooperatively contacted.

Compared with the prior art, the battery cover has fewer structural components and a relatively simple structure, and a snap portion is disposed on the inner wall of the cover body, so that the cover body can be well clamped and not easily portable. The body of the electronic device is detached. The battery cover structure is relatively simple and easy to operate when opened and closed, and is very convenient to use.

The battery cover structure of the present invention is applicable to a portable electronic device such as a mobile phone or a personal digital assistant (PDA). In the present embodiment, a mobile phone is taken as an example.
