Description

Folding cover for electronic equipment

[Technical Field]

The present invention relates to the technical field of protective cover design of electronic devices, and in particular to a folding protective cover for an electronic device.

 【Background technique】

As consumer electronics consumes more and more power, electronic devices such as mobile phones and ipads require small size and large screens. Therefore, the battery capacity of the battery is limited, and batteries with larger capacity cannot be built into the electronic device. The backup battery of an electronic device means that it can be worn around the periphery of the electronic device and can be transferred to the built-in battery of the electronic device at any time.

At present, most of the backup batteries are designed on the back of the electronic device, and the power is transferred to the built-in battery through the interface. In order to further increase the capacity of the backup battery, the folding protective cover of the electronic device is fully utilized, and a card type backup battery is packaged in the folding protective cover. With a thickness of only about 0.5 mm, this battery can be stacked and has a certain degree of softness, making it ideal for packaging on electronic folding covers. However, since the folding protective cover often needs to be flipped, even a 360° flip fit, the backup battery in the upper cover of the existing folding protective cover is electrically connected to the lower cover or the electronic device through the upper wire, and the upper cover and the lower cover. When the joint is rotated, the wire is repeatedly bent, which easily causes metal fatigue in the metal wire in the wire. For example, the metal wire breaks when the conventional wire life is only 15,000 times.
