This application is a National Phase of PCT Patent Application No. PCT/CN2017/076477 having International filing date of Mar. 13, 2017, which claims the benefit of priority of Chinese Patent Application No. 201720138160.1 filed on Feb. 15, 2017. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety.
The present disclosure relates to a field of electronic technology, and more particularly to an electronic device with a detachable battery cover.
Removable battery covers used in devices, such as current mobile terminals, are basically snap-fit battery covers. Connection between a device body and a battery cover can be implemented through a buckle structure of the battery cover and a lock structure of the battery cover device body. Because the snap-fit battery cover is probably not snapped in place properly, there is a gap between the device body and the battery cover, or the snap-fit battery cover may be snapped too tight so that the battery cover is hard to be disassembled, which is inconvenient for the user.
In one issue, number of fasteners disposed on the snap-fit battery cover has to be set according to the size of the screen. As phone screens are getting larger, more fasteners for the battery cover are needed, so that producing the battery cover is more difficult. When deviation of the size of the fastener occurs, there may be an unavoidable gap after the battery cover is snapped on.
In order to solve the problem of the above-mentioned prior art, one objective of the present disclosure is to provide an electronic device with a detachable battery cover.
The present disclosure provides an electronic device with a detachable battery cover, which comprises a device body, a battery cover, at least one first attachment body, and at least one second attachment body. The first attachment body is disposed on the device body. The second attachment body is disposed on the battery cover. The first attachment body and the second attachment body are attached to each other to connect the device body and the battery cover.
Further, the device body comprises a bottom shell and a front shell fastened to the bottom shell. A first receiving groove is formed on a fastening edge of the front shell. The first attachment body is received in the first receiving groove.
Further, a through hole is opposite to the first receiving groove and formed on the bottom shell. The first attachment body passes into the through hole.
Further, a second receiving groove is opposite to the first receiving groove and formed on the battery cover. The second attachment body is disposed in the second receiving groove.
Further, the first attachment body and the second attachment body are attached to each other by magnetic attraction.
Further, the first attachment body and the second attachment body are attached to each other by vacuum attraction.
In particular, the electronic device is a smart phone or a tablet computer.
Advantageous effects of the present disclosure: the device body and the battery cover of the present disclosure are connected to each other through the first attachment body and the second attachment body so that the battery cover is firmly attached to the electronic device, and it is easy to detach the battery cover. Besides, attachment capacity of the first attachment body and the second attachment body will not be weakened with the increase in the number of detachments so that service life can be extend and quality of the electronic device can be improved.
The following description in conjunction with the accompanying drawings, the above and other aspects, features, and advantages of embodiments of the present disclosure will become more apparent from the accompanying drawings in which:
Hereinafter, the embodiments of the present disclosure are described in detail with reference to the accompanying drawings. However, it is embodied in many different forms and embodiments of the present disclosure, and the present disclosure should not be construed as limited to the particular embodiments set forth herein. Rather, these embodiments are given in order to explain the principles of the disclosure and its practical application to thereby enable others skilled in the art to understand the disclosure for various embodiments and various modifications as suited to the particular use contemplated.
The same reference numerals throughout the specification and the drawings may be used to denote like elements. It will be understood that, although the terms may be used herein “first”, “second”, etc., to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element.

In the embodiment, the first attachment body 30 and the second attachment body 40 are attached to each other by magnetic attraction. For example, the first attachment body 30 and the second attachment body 40 are magnets, and both of them use magnetic attraction with different magnetic poles. The first attachment body 30 may be a magnet, and the second attachment body 40 is made of material magnetically attracted by the magnet, such as iron. Number, shape, and size of the first attachment body 30 and the second attachment body 40 are equal, which can be arrangement according to actual needs, and is not limited by the present disclosure. In the specific implementation, the place of the first attachment body 30 and the second attachment body 40 are oppositely arranged. The first attachment body 30 of the electronic device 10 and the second attachment body 40 of the battery cover 20 are oppositely attached when the electronic device 10 connects to the battery cover 20 so that the electronic device 10 and the battery cover 20 are connected to each other.
As another embodiment of the present disclosure, the first attachment body 30 and the second attachment body 40 are attached to each other by vacuum attraction. For example, the first attachment body 30 and the second attachment body 40 can be made of silica gel or other soft colloidal material. Both of them are connected and pushed against each other to squeeze out air between them so that atmospheric pressure from outside is greater than the pressure between them, and the first attachment body 30 and the second attachment body 40 are attached to each other. It should be stated that the first attachment body 30 and the second attachment body 40 can be attached to each other according to other suitable methods.
As described above, the device body and the battery cover of the present disclosure are connect to each other through the first attachment body and the second attachment body so that the battery cover is firmly attached on the electronic device and easy to detach the battery cover. Besides, attachment capacity of the first attachment body and the second attachment body will not be weakened with the increase in the number of detachments so that service life can be extend and quality of the electronic device can be improved.
While shown already with reference to specific embodiments and described in the present invention, those skilled in the art will appreciate that, without departing from the spirit and scope of the invention being indicated by the claims and their equivalents as defined, may be made in the form here and various changes in detail.
