The purpose of present invention is realized by the following conceptions:
A case having battery box for smart phone/tablet comprising:
a box of smart phone/tablet, which is a rectangular open box having four side walls and a bottom, a chamber of the box of smart phone/tablet is the same of the size and shape of the smart phone/tablet, a top of each side wall is bended inward to form a holding ring for the smart phone/tablet;
a battery box for containing batteries, which is a rectangular open box having a bottom which is a part bottom of the box of smart phone/tablet;
a battery electric connecting means for connecting the batteries with a power plug of the smart phone/tablet;
a cover for closing the battery box and holding the batteries in the battery box; a lock means for locking the cover with the battery box.
In another embodiment, the battery box and the box of smart phone/tablet are separated single unite, they are connected together by a connecting means.
The battery box has four side walls and a chamber for holding 8 AA or AAA batteries, each outside surface of the four side walls has a hump for locking the cover with the battery box.
The cover is an open rectangular box having four side wall and a bottom, each inside surface of the four sides walls of the cover has a concavity, which is corresponding to the hump of the battery box, the humps and the concavities consist of the lock means, during the cover being put on the battery box the humps enter the concavities respectively, thereby the cover of battery box is locked with the battery box.
the battery electric connecting means comprises eight connecting pieces and eight connecting springs, four connecting pieces and four connecting springs consist of a connecting group, in the connecting group the four connecting pieces and four connecting springs are connected in series, thereafter two connecting groups are connected in parallel and then connected with the power plug of the smart phone/tablet.
A wireless charging card is fixed on a back surface of the bottom of the cover, and the wireless charging card is connected with a switch in series then with the two connecting groups in parallel, when the wireless charging card being powered the switch on, otherwise the switch off.
The case having battery box for smart phone/tablet brings big convinces to the smart phone/tablet users. The battery box can hold eight AA or AAA sized batteries, which provide enough energy to a smart phone or tablet to work a long time. Also, the case having battery box for smart phone/tablet makes people, who travel far and long distance, such as climbers and hikers or work in open country, possible to carry enough regular AA/AAA sized dry batteries, so that in case they get lost for many days they can still utilize their additional AA/AAA batteries to call for help.
