Battery cover locking structure

The present invention relates to a battery cover locking structure, and more particularly to a battery cover locking structure applied to an electronic device such as a mobile phone.

During the use of the portable electronic device, it is often necessary to replace the battery of the portable electronic device. Therefore, the battery cover of the conventional portable electronic device generally needs to be easily disassembled and assembled to replace the battery.

A conventional battery cover is generally in the shape of a cover and includes a body, an end portion, two side walls, and a bottom wall. The main body has a substantially rectangular plate shape, and the two side walls and a bottom wall are respectively bent by the edge of the main body. The bottom wall is convexly provided with two hooks, which can be engaged with the recesses of the mobile phone body; the battery cover extends with two latches on the end of the bottom wall to cooperate with the mobile phone body card slot. When assembling, first align the end and the two side walls of the battery cover with the mobile phone body, the second card is aligned with the card slot of the body, and then push the battery cover toward the two blocks, and the second card of the battery cover is stuck in the card slot. The other side wall is attached to the peripheral wall of the mobile phone body, and the two hooks of the bottom wall of the battery cover are engaged in the recess of the body. When you need to remove the battery cover, push the battery cover and reverse the above steps.

However, although the structure can realize the function of disassembly and assembly at any time, after the cover body is mounted on the body, the relative sliding phenomenon of the cover body and the body body is easy to occur in the installation direction of the cover body relative to the body, and the locking is not stable and reliable.

In view of the above, it is necessary to provide a battery cover lock structure that prevents the battery cover from sliding.

A battery cover locking structure for locking a battery cover on a housing, the battery cover locking structure comprising a clamping portion disposed on the housing, an operating member slidably mounted on the battery cover, and a sliding member, the sliding member The holding portion is provided with a retaining groove, and the retaining groove is provided with a sloped surface. When the sliding member is clamped in the holding groove, the battery cover is locked on the casing when the sliding operation is performed. When the piece is driven, the sliding member pulls the through groove along the inclined surface to release the holding of the battery cover and the casing.

Compared with the conventional battery cover locking structure, the battery cover locking structure realizes the locking and dismounting of the battery cover and the housing by the operation member driving the plate body of the sliding member and the clamping groove to be locked and unlocked. Moreover, the battery cover is relatively firm when assembled, and the relative sliding phenomenon of the cover body and the body body is not easily generated in the mounting direction of the cover body relative to the housing.
