Battery cover locking structure and electronic device having the same

The invention relates to a battery cover locking structure and an electronic device having the battery cover locking structure.

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.

The conventional battery cover includes a main body, one end portion, two side walls, and a bottom end wall. The main body has a substantially rectangular plate shape, and the two side walls and one bottom end wall are respectively formed by bending the main body edge. Two hooks are protruded from the bottom end wall to engage with the recess of the mobile phone casing; two end portions of the battery cover extend from the end of the bottom end wall to cooperate with the slot of the mobile phone housing . When assembling, first align the end and the two side walls of the battery cover with the mobile phone casing, the two blocks are aligned with the card slot of the casing, and then slide the battery cover toward the two blocks, and the two cards of the battery cover are stuck on the card. In the slot, the other side wall is attached to the peripheral wall of the mobile phone casing, and the two hooks of the bottom end wall of the battery cover are engaged in the recess of the casing. When you need to remove the battery cover, slide the battery cover and reverse the above steps.

However, although the structure can be disassembled and assembled at any time, after the battery cover is mounted on the casing, the relative sliding of the battery cover and the casing is likely to occur in the sliding direction of the battery cover relative to the casing, and the locking is insufficient. stable.

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

It is also necessary to provide an electronic device having a battery cover locking structure.

A battery cover locking structure for locking a battery cover on a casing, the battery cover locking structure comprising a holding groove provided in the casing and an operating member slidably mounted on the battery cover, the operating member is provided with a sliding a button and a holding body disposed perpendicularly to a sliding direction of the sliding button. When the holding body is held in the holding groove, the battery cover is locked on the housing in a sliding direction of the housing, and when sliding the sliding button away from the battery cover The sliding button drives the retaining body away from the retaining slot to release the locking of the battery cover and the housing.

An electronic device includes a housing, a battery cover that is disposed on the housing, and a battery cover locking structure. The housing is provided with a holding slot, and the battery cover locking structure includes an operating component that is slidably mounted on the battery cover. The operating member is provided with a sliding button and a holding body disposed perpendicularly to the sliding direction of the sliding button. When the holding body is held by the holding groove, the battery cover is locked on the housing in the sliding direction of the housing, and is away from the battery. When the cover slides the slide button, the slide button drives the retaining body away from the retaining slot to release the locking of the battery cover and the housing.

The battery cover locking structure realizes the locking and dismounting of the battery cover and the housing by the clamping and unlocking of the holding body of the operating member and the holding groove on the housing, and the battery cover is relatively firm when assembled. The relative sliding phenomenon of the battery cover and the housing is not easily generated in the sliding direction of the battery cover relative to the housing.
