Abstract

The present invention relates to a mobile terminal, and in particular to a mobile power bank and a combined terminal device formed by splicing the mobile power bank and the mobile terminal. The mobile power bank comprises a display screen, a storage battery located below the display screen, and a casing for holding the display screen and the storage battery. The mobile power bank is generally flat-plate shaped with a front surface and a back surface. Both an area of a display region of the display screen and an area of an occupied region of the storage battery are not less than 70% of the front surface area. A volume of the storage battery can be increased without changing the thickness of the storage battery, providing an extended charging service for mobile phones. In addition, the mobile power bank of the present invention has a large display screen, when the mobile power bank is connected to a mobile terminal, such as a mobile phone, the display screen and a display screen of the mobile terminal may perform display at the same time.

Claims

1. A mobile power bank with a display screen, characterized by comprising:

a display screen;

a storage battery located below said display screen; and

a casing for holding said display screen and said storage battery,

wherein said mobile power bank is generally flat-plate shaped with a front surface and a back surface;

said display screen is located on said front surface and provides at least a part of said front surface; and

both an area of a display region of said display screen and an area of an occupied region of said storage battery are not less than 70% of the area of said front surface;

said casing has a holding structure for holding a mobile terminal at said back surface; and

said holding structure comprises a rear magnetic adsorbing element arranged adjacent to said back surface, for adsorbing a corresponding rear magnetic adsorbing element arranged on said mobile terminal, so as to hold said mobile terminal at said back surface.

2. The mobile power bank according to claim 1, characterized in that said mobile power bank is generally substantially rectangular flat-plate shaped.

3. The mobile power bank according to claim 1, characterized in that the area of the display region of said display screen is not less than 75%, 80%, 85%, 90% or 95% of the area of the front surface, and/or the area of the occupied region of said storage battery is not less than 75%, 80%, 85%, 90% or 95% of the area of the front surface.

4. The mobile power bank according to claim 1, characterized in that said mobile power bank has the functions of receiving external power to charge said storage battery, supplying power for said display screen and an external device, and receiving display data from said external device for displaying on the display screen.

5. The mobile power bank according to claim 4, characterized in that said external device is a mobile terminal.

6. The mobile power bank according to claim 1, characterized by further comprising:

a first side surface and a second side surface located at two sides of said mobile power bank, wherein said first and second side surfaces are planes parallel to each other; and

a first magnetic adsorbing element provided at said first side surface and a second magnetic adsorbing element provided at said second side surface, for adsorbing a corresponding side magnetic adsorbing element arranged at a side surface of a mobile terminal, so that any side of said mobile power bank can hold said mobile terminal by adsorption.

7. The mobile power bank according to claim 6, wherein said first magnetic adsorbing element does not protrude out of said first side surface, and said second magnetic adsorbing element does not protrude out of said second side surface.

8. The mobile power bank according to claim 6, characterized by further comprising:

a first conductive contact provided at said first side surface and a second conductive contact provided at said second side surface, for mutually electrically contacting with a conductive contact correspondingly provided at the side surface of said mobile terminal held by said mobile power bank, so as to provide data transmission from said mobile terminal to said mobile power bank and discharge from said mobile power bank to said mobile terminal.

9. The mobile power bank according to claim 8, characterized in that at least one of said first conductive contact and said second conductive contact is made of an elastic material or biased by a spring so as to be able to move in a direction perpendicular to the side surface where it is located.

10. The mobile power bank according to claim 9, characterized in that said first conductive contact is composed of a plurality of bow-shaped metal sheets, and said second conductive contact is recessed into said second side surface;

and

when said first conductive contact and said second conductive contact are in mutual electrical contact with a conductive contact correspondingly provided at the side surface of said mobile terminal held by said mobile power bank, said second side surface of said mobile terminals and said side surface of said mobile terminals are bonded in alignment with each other by deforming said first conductive contact in the direction perpendicular to the side surface where it is located.

11. The mobile power bank according to claim 8, characterized in that at least one of said first conductive contact and said second conductive contact is formed as an active contact which can move between an extended position and a retracted position, wherein the active contact protrudes out of the side surface where it is located when in the extended position.

12. The mobile power bank according to claim 11, wherein the side surface where said active contact is located is provided with:

a recessed portion for accommodating said active contact, and

a detachable contact cover for sealing said recessed portion.

13. The mobile power bank according to claim 11, characterized in that said first side surface has a first groove, and the first conductive contact is rotatably connected into the first groove;

and said first conductive contact can rotate out of said first groove so as to make mutual electrical contact with a conductive contact correspondingly provided at the side surface of said mobile terminal, and said first conductive contact can rotate inwardly to said first groove so as to disconnect the electrical contact with the conductive contact correspondingly provided at the side surface of said mobile terminal.

14. A combined terminal device composed by splicing one or more mobile terminals and at least one mobile power bank as claimed in claim 1 in the width direction and/or length direction of said display screen of said mobile power bank, wherein said mobile terminal provides said mobile power bank with display data of a display screen thereof, and said storage battery of said mobile power bank supplies power for said mobile terminal.

15. The combined terminal device according to claim 14, characterized in that, in the splicing direction, said display screen of said mobile power bank has the same width or length as a display screen of said mobile terminal.
