Portable electronic device and battery cover structure thereof

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

With the development of science and technology, various electronic devices have been filled in daily life and become an indispensable tool for modern people. For example, the popularity of mobile phones has changed the mode of communication among modern people. Users can now contact distant relatives and friends at any time and any place. The mobile phone has evolved from a single call function to a multimedia device that integrates various functions such as audio-visual playback, video capture, and data transmission.

Mobile phones, which are common on the market today, use a battery cover to cover, protect the battery, and to maintain the appearance integrity of the mobile phone. Generally, in order to allow the battery cover to be firmly connected to the body, a plurality of hooks and card slots are provided around the battery cover and the battery compartment of the body. The user must align the hook with the card slot and apply force to engage the hook in the card slot to connect the battery cover to the body.

However, this way of applying the hook and the card slot structure takes up action. The internal space of the telephone makes it impossible to use the internal space of the mobile phone more effectively. Moreover, the structure of the plurality of hooks and the card slot increases the complexity of the structure of the body and the battery cover, thereby causing difficulty in mold design. In addition, the use of the hook and the card slot to engage the battery cover and the body may cause inconvenience in use. For example, the user must align the hooks with the card slots to apply force to engage the hooks in the card slots. This action is not only time-consuming, but also causes the hooks to break when the force is applied. In addition, after repeatedly disassembling the battery cover for a long time, the hooks and the card slots are prone to material wear, so that the hooks cannot be tightly engaged with the card slots, causing the battery cover to loosen or even fall off.

Therefore, the present invention provides a battery cover structure for a portable electronic device. The magnetic body between the ferromagnetic component of the portable electronic device body and the ferromagnetic component of the battery cover structure is used to adsorb and connect the cover body to the body. .

According to an aspect of the invention, a battery cover structure for a portable electronic device includes a cover body and at least one second ferromagnetic element. The cover body has a second contact surface, and the second ferromagnetic element is disposed on the second contact surface. The cover system is coupled to one of the portable electronic devices by magnetic attraction between the second ferromagnetic component and the at least one first ferromagnetic component of the portable electronic device.

According to another aspect of the present invention, a portable electronic device is provided, including a body, at least a first ferromagnetic element, and a battery cover structure. The body has a first contact surface and a battery slot. The first ferromagnetic component is disposed on The first contact surface, the battery slot is for accommodating a battery. The battery cover structure includes a cover and at least one second ferromagnetic element. The second ferromagnetic element is disposed on the second contact surface, and the cover system is coupled to the body by magnetic attraction between the second ferromagnetic element and the first ferromagnetic element. When the cover is attached to the body, the second contact surface contacts the first contact surface, and the cover system covers the battery slot.

The battery cover structure of the portable electronic device of the present invention uses magnetic force to connect the cover body to the body, which simplifies the structural design of the cover body and the body, saves the internal space of the portable electronic device, and reduces the complexity of the mold opening. In turn, the cost is reduced.
