Battery cover structure

The present invention relates to a battery cover structure, and more particularly to a battery cover structure for a portable electronic device.

With the continuous updating and development of technology, portable electronic devices such as mobile phones or personal digital assitants (PDAs) are showing a trend of diversified functions, which requires a larger battery to provide sufficient working energy. Larger batteries are generally larger in size.

The battery cover for covering a battery is generally a single-type battery cover structure, which generally includes an upper wall, a left side wall, a right side wall and a bottom wall, and the battery cover extends on the upper wall of one end of the bottom wall. There is a protrusion which can be engaged with the groove of the body of the mobile phone. When assembling, firstly, the upper 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. At the same time, the left side wall, the right side wall and the bottom wall are attached to the peripheral wall of the mobile phone body. The unitary battery cover structure achieves the purpose of coating the battery by directly engaging with the body of the portable electronic device.

However, when it is required to cover a large-capacity battery having a large size, the conventional single-cell battery cover structure must be coupled to it by changing the structure of the portable electronic device body. This means redesigning and producing the portable electronic device body that has been designed in a general size, which causes a serious waste of resources and increases the overall production capacity of the portable electronic device. Cost.

In view of the above, it is necessary to provide a "two-piece" battery cover structure that can easily cover a large-capacity large-capacity battery.

A battery cover structure includes a body, a first cover body and a second cover body. The body has a battery receiving portion for accommodating a battery, and the battery portion is received in the battery receiving portion. The first cover body and the second cover body respectively comprise a side wall, a top wall connected to the side wall, and a connecting wall connecting the side wall and the top wall, the top of the first cover body and the second cover body The wall and the connecting wall are each formed into a cavity; the side wall of the second cover is provided with an elastic piece, and the first cover and the second cover are detachably mounted on the body, and the elastic piece and the body are buckled The top wall protrudes from the body, and the cavity of the first cover and the cavity of the second cover cooperate to cover a portion of the battery exposing the battery receiving portion.

Compared with the prior art, the battery cover structure adopts a "two-piece" cover design of the first cover body and the second cover body, and the first cover body and the second cover body cooperate with each other to form a large size. The battery is completely covered in the body.

The battery cover structure of the present invention is suitable for a portable electronic device such as a mobile phone or a personal digital assistant (PDA). In the present embodiment, a mobile phone will be described as an example.

The top wall 131 and the connecting wall enclose a cavity 1311 for receiving a portion of the battery 20 exposed outside the battery receiving portion 115. A resisting block 135 protrudes from a side of the end wall 134 facing one side of the cavity 1311. The resisting block 135 is for resisting the elastic latching member 119. A latch 136 is protruded from a side of the end wall 134 facing one side of the cavity 1311. The block 136 is configured to be embedded in the snap hole 1121. The two side walls 132 and 133 protrude from one side of the cavity 1311 with a positioning piece 137 having an "L" shape in section. The positioning piece 137 is disposed corresponding to the second holding groove 117. The positioning piece 137 includes an embedded portion 1371 and a resisting portion 1372 perpendicularly connected to the embedded portion 1371. The embedded portion 1371 can be embedded in the second retaining groove 117 and resist the second retaining wall 1171. An elastic piece 138 is protruded from each of the two side walls 132 and 133 facing one side of the cavity 1311 . The elastic piece 138 has a substantially rectangular sheet shape and is disposed corresponding to the first card slot 26 of the body 11. The elastic piece 138 protrudes from a side wall 1381 of the cavity 1311 to define an insertion groove 1382. The embedded groove 1382 corresponds to the bump 1182. One end of the top wall 131 away from the end wall 134 is a second mating surface 139 . The second mating surface 139 defines a plurality of rectangular blocks 1391 corresponding to the positioning holes 127 of the first cover 12 . The block 1391 is embedded in the positioning hole 127. When the second cover 13 is mounted on the body 11, its top wall 131 protrudes from the body 11.
