Battery cover lock structure

The invention relates to a battery cover latch structure, in particular to a battery cover latch structure applied to a portable electronic device such as a mobile phone.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used, and batteries that provide portable electronic devices have to be replaced with energy consumption, so that the battery can be easily installed. People have designed many battery cover lock structures.

The battery cover latch structure of the conventional portable electronic device is mostly clamped on the body by using a hook and a buckle structure, that is, a pair of hooks are arranged at one end of the battery cover, and a latch pin is disposed at the other end, corresponding to the body. One pair of card slots is provided at one end, and one button lock hole is provided at the other end. When installing, first insert the hook of the battery cover into the card slot of the body, and then rotate the battery cover with the card slot as the axis toward the body and press the battery cover until the card lock pin of the battery cover is locked into the lock hole of the body. .

Although the battery fixing device can firmly fix the battery in the body, once the battery cover is combined with the body, the battery cover is difficult to disassemble, which causes inconvenience in use.

In view of this, it is necessary to provide a battery fixing device that is easy to operate.

A battery cover latch structure includes a battery cover and a casing, the casing opening a concave a battery cover that is engaged in the recess, the battery cover includes a first surface facing the housing, the first surface is provided with a plurality of rotating bodies, and a protrusion is protruded from each of the rotating bodies a plurality of guiding slots corresponding to the rotating body, the housing opening a plurality of card slots engaged with the engaging portions, and a plurality of openings penetrating the card slots, the rotating body rotatably The accommodating portion is inserted into the slot by the opening, and when the engaging portion enters the card slot, the rotating body is rotated to make the engaging portion The card slot is engaged.

Compared with the prior art, after the engaging portion enters the card slot, the rotating body is rotated to engage the engaging portion with the card slot to engage the battery cover with the housing. together. When the battery cover needs to be removed, the battery cover is rotated in the opposite direction to release the engagement between the engaging portion and the card slot, and the battery cover can be taken out from the groove.

1 is an exploded view of a battery cover latch structure of a preferred embodiment of the present invention; FIG. 2 is an exploded view of the battery cover latch structure of FIG. 1; FIG. 3 is a battery cover of FIG. FIG. 4 is a schematic view showing another view of the battery cover latch structure shown in FIG. 3; FIG. 5 is a view showing the battery cover shown in FIG. FIG. 6 is a schematic view showing another view of the battery cover latch structure shown in FIG. 5.

The invention discloses a battery cover latch structure, which is suitable for a portable electronic device such as a mobile phone. In the embodiment, a mobile phone is taken as an example for description.

Referring to FIG. 1 , the battery cover latch structure 100 is used to engage a battery 10 therein. The battery cover 20 includes a battery cover 20 and a housing 30 that is engaged with the battery cover 20 .

Referring to FIG. 2 , the battery cover 20 is substantially an elliptical plate body including a first surface 22 facing the housing 30 and a second surface 24 opposite the first surface 22 . The first surface 22 is symmetrically protruded from the two circular arc-shaped rotating bodies 222. One rotating body 222 is disposed adjacent one end of the battery cover 20, and the other rotating body 222 is disposed adjacent to the other end of the battery cover 20. Each of the rotating bodies 222 protrudes outwardly from a side of the other rotating body 222 to form a square engaging portion 224 . Each of the engaging portions 224 defines a matching groove 226 having an arc-shaped cross section toward one side of the first surface 22 . A plurality of bumps 242 are respectively protruded from the second surface 24 corresponding to the rotating body 222, and the bumps 242 are used to enhance the roughness of the second surface 24.

The housing 30 is a square frame that includes a bottom wall 32 and a peripheral wall 34 disposed on the bottom wall 32. The bottom wall 32 includes an outer surface 322 and an inner surface 324. A recess 3221 is defined in the outer surface 322 corresponding to the battery cover 20 to form a slot bottom wall 3222 on the housing 30. The shape and size of the recess 3221 is comparable to the shape and size of the battery cover 20. The recess 3221 is for receiving the battery cover 20. The groove bottom wall 3222 is recessed with two curved guide grooves 3223 corresponding to the rotating body 222, so as to form two opposite guide groove side walls 3224 on the inner surface 324. A slot 3225 is formed in the side wall 3224 of the guide slot for engaging with the engaging portion 224. An opening 3226 is defined in the bottom wall 3222 of the slot, and the opening 3226 is penetrated through the slot 3225. The engaging portion 224 enters the card slot 3225 through the opening 3226. A protrusion 3242 protruding from the inner surface 324 of the housing 30 corresponding to the engaging groove 226 is formed. When the engaging portion 224 is engaged in the slot 3225, the protrusion 3242 is engaged with the protrusion 3242. The fitting groove 226 is inside. The housing 30 is recessed between the guiding slots 3223 for accommodating the battery 10 Slot 36.

Referring to FIG. 3 and FIG. 4 together, when the battery cover latch structure 100 is used, the battery 10 is first placed in the accommodating groove 36, and then the engaging portion 224 is aligned with the opening 3226. The battery cover 20 is then pressed into the recess 3221. The latching portion 224 enters the slot 3225 through the opening 3226. The rotating body 222 is located in the guiding slot 3223. And resisting the side wall of the guiding groove 3223. Next, referring to FIG. 5 and FIG. 6, the battery cover 20 is rotated until the engaging portion 224 is engaged with the slot 3225, and the protrusion 3242 is engaged with the engaging slot 226, so that the battery cover is 20 is securely engaged with the housing 30.

When the battery 10 needs to be taken out, the bump 242 is pressed to rotate the battery cover 20 in the opposite direction, so that the engagement between the protrusion 3242 and the engaging groove 226 is released. When the engaging portion 224 is aligned with the opening 3226 again, the engagement between the engaging portion 224 and the slot 3225 is also released. At this time, the battery cover 20 can be taken out from the recess 3221, and the battery 10 can be taken out. .

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and equivalent modifications or variations made by those skilled in the art in accordance with the spirit of the present invention are It should be covered by the following patent application.
