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 portable electronic device generally includes a recess formed in the housing of the portable electronic device and a battery cover that can cover the recess. After the battery is loaded into the recess, the battery cover is secured to the housing to confine the battery within the recess. In order to fix the battery cover to the casing, a pair of hooks are generally arranged at one end of the battery cover, and a latch pin is disposed at the other end, correspondingly, a pair of card slots are arranged at one end of the casing, and a buckle is arranged at the other end. hole. When installing, first insert the hook of the battery cover into the card slot of the housing, and then rotate the battery cover with the card slot as the axis toward the housing direction and press the battery cover until the latch pin of the battery cover is snapped into the housing. In the keyhole.

Although the battery cover latch structure can firmly fix the battery in the casing, once the battery cover is combined with the casing, the battery cover is difficult to disassemble, which causes inconvenience in use. In addition, the battery cover is engaged with the housing by the cooperation of the hook and the card slot, and the battery cover and the housing are also difficult to be The gap is not generated, and liquid such as water enters the groove, thereby deteriorating the performance of the battery.

In view of the above, it is necessary to provide a battery cover latch structure that is easy to operate and waterproof.

A battery cover latching structure includes a body and a battery cover that is engaged with the body, and a receiving cavity for accommodating the battery is disposed on the body, the battery cover latching structure further includes a first magnetic component and a second magnetic component, the first magnetic component is disposed around the entire circumference of the battery cover, the body defines a recess surrounding the accommodating cavity, and the second magnetic component is fixed in the recess, the second magnetic component The magnetic pole facing the surface of the first magnetic element is opposite to the magnetic pole of the first magnetic element facing the surface of the second magnetic element, and the attraction between the first magnetic element and the second magnetic element causes the entire battery cover The periphery is tightly coupled to the second magnetic member to close the receiving cavity.

Compared with the prior art, the entire circumference of the battery cover is tightly coupled with the second magnetic component to close the accommodating cavity, thereby effectively preventing outside water or the like from entering the accommodating cavity. When the battery cover needs to be opened, the battery cover can be opened by overcoming the attraction between the first magnetic element and the second magnetic element.

The invention discloses a battery cover latch structure, which is suitable for a portable electronic device such as a mobile phone.

Referring to FIG. 1 and FIG. 2, the battery cover latch structure 100 is used for A battery 10 is locked therein, and includes a battery cover 20, a first magnetic component 30, a second magnetic component 40, and a body 50.

The battery cover 20 is substantially a square plate-like body including a first surface 22 remote from the body 50 and a second surface 24 opposite the first surface 22. The battery cover 20 may be made of a thermoplastic resin material such as one or more of polyvinyl chloride, polycarbonate, and polystyrene.

The first magnetic element 30 is a hollow plate-like body or an annular body, and its outer contour is shaped and sized to correspond to the battery cover 20. The first magnetic component 30 is fixed to the first surface 22 in a manner of integral molding or hot melt.

The second magnetic element 40 is a hollow plate-like body having a shape and a size corresponding to the shape and size of the first magnetic element 30. A gap 42 is defined in the second magnetic component 40. The gap 42 facilitates separation of the battery cover 20 from the body 50. The specific principle will be described in detail below. The magnetic pole of the second magnetic element 40 facing the surface of the first magnetic element 30 is opposite to the magnetic pole of the first magnetic element 30 facing the surface of the second magnetic element 40. The second magnetic element 40 is fixed to the body 50.

The body 50 defines a receiving groove 52 for receiving the battery cover 20, so that a bottom wall 522 is formed on the body 50. A recess 524 for receiving the battery 10 and a recess 526 corresponding to the first magnetic component 30 are defined in the bottom wall 522 of the slot, and the recess 526 surrounds the receiving cavity 524. The shape and size of the groove 526 and the second magnetic The shape and size of the component 40 are equivalent. The second magnetic component 40 is fixed in the recess 526 in a manner of adhesive bonding or heat fusion.

One end of the body 50 defines an opening groove 54 corresponding to the notch 42 , and the opening groove 54 communicates with the groove 526 . When the battery cover 20 is fixed to the body 50, the opening groove 54 is aligned with the notch 42.

Referring to FIG. 3 , when the battery 10 latch structure 100 is assembled, the first magnetic component 30 is first fixed (eg, thermally fused) to the first surface 22 to be integrated with the battery cover 20 . The outer contour of the first magnetic component 30 is flush with the peripheral sidewall of the battery cover 20, and the first magnetic component 30 is circumferentially disposed on the entire circumference of the battery cover 20. The second magnetic element 40 is then fixed (e.g., thermally fused) within the recess 526. Next, the battery cover 20 is aligned with the accommodating groove 52. Finally, the battery cover 20 is pressed into the receiving slot 52 in the direction of the body 50. At this time, the opening slot 54 is aligned with the notch 42 and the second magnetic component 40 is attached. Attached to the second surface 24 of the battery cover 20 and aligned with the first magnetic component 30, that is, the second magnetic component 40 is also disposed around the entire circumference of the battery cover 20. Thus, the battery cover 20 is firmly fixed in the accommodating groove 52 by the attraction between the first magnetic element 30 and the second magnetic element 40. In addition, since the first magnetic element 30 and the second magnetic element 40 are attached to the entire circumference of the battery cover 20, the entire circumference of the battery cover 20 is tightly coupled with the second magnetic element 40. The accommodating cavity 524 is closed, so that water or the like from the outside is effectively prevented from entering the accommodating cavity 524.

When the battery cover 20 needs to be opened, the user's finger sequentially passes through the opening groove 54 and the notch 42 until the battery cover 20 is abutted, and then the force of the first magnetic element 30 and the second magnetic element 40 is overcome. Until the battery cover 20 is separated from the body 50, the battery cover 20 is opened.

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