Battery cover opening and closing mechanism

The invention relates to a battery cover opening and closing mechanism, in particular to a battery cover opening and closing mechanism applied to a portable electronic device such as a mobile phone and a personal digital assistant.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used, and portable electronic devices use batteries as their energy source. The batteries are mounted in the portable electronic device by a battery cover that is inserted into the casing of the portable electronic device to provide power to the portable electronic device. As the battery energy is continuously consumed, the battery of the portable electronic device must be replaced, so various battery cover structures have been designed for convenient and reliable battery replacement.

A conventional battery cover includes a top wall, a left side wall, a right side wall, and a bottom wall. The top wall has a substantially rectangular plate shape, and the left side wall and the right side wall are respectively formed by bending and extending from opposite left and right side edges of the top wall. The bottom wall is formed by bending and extending the other side wall of the top wall, and the two ends of the bottom wall are respectively connected to the left and right side walls to form a substantially rectangular concave shape, and the one end is open and the one end is closed. space. The battery cover has a protrusion extending from the open end wall of the top wall of one end of the bottom wall, and the protrusion is engageable with the groove of the mobile phone body. When assembling, firstly, the top wall, the left side wall and the right side wall of the battery cover face the mobile phone body, and the protruding portion faces the groove of the body, and then pushes the battery cover toward the protruding portion, and the protruding portion of the battery cover is stuck in the groove. With the left side The wall, the right side wall and the bottom wall are attached to the peripheral wall of the mobile phone body. The battery cover structure of this type can remove the battery cover to replace the battery. However, when the battery cover is removed, the battery cover needs to be pushed backwards, because the left side wall, the right side wall and the bottom wall are attached to the mobile phone body. The battery cover is not easy to be detached from the mobile phone body, and the disassembly and assembly is inconvenient.

In view of this, it is necessary to provide a battery cover opening and closing mechanism that is convenient to use and disassemble.

A battery cover opening and closing mechanism includes a body, a battery cover and a release device; the body has a back cover, and the battery cover is detachably mounted on the back surface of the body by the release device; At least one hook is protruded from the back surface of the body, and a gap is formed on the battery cover corresponding to the hook; the release device includes a fixing seat, an elastic member and a release member. The seat is fixedly mounted on the inner wall of the battery cover and located under the notch; the elastic member is mounted on the fixed seat corresponding to the hook; the release member is slidably mounted on the fixed seat and The release member is placed in the installation space surrounded by the notch portion and the fixing seat, and the release member abuts against the elastic member to push the elastic member to engage or separate with the hook to realize the battery cover and The body is locked or unlocked.

Compared with the prior art, the battery cover opening and closing mechanism releases or engages the elastic member of the release device with the hook on the body by pressing the release member slidably mounted on the battery cover. The battery cover and the body are disassembled and installed easily and quickly. The battery cover opening and closing mechanism has a simple structure and is convenient to operate.
