Abstract

An electronic device includes a main body and an input body. The main body has a display unit and a first contact portion rotatably connected to the display unit. The first contact portion has a first surface and a second surface opposite to the first surface, and at least one part of the first contact portion has a thickness smaller than a thickness of the display unit. The input body includes a second contact portion with a contact surface. When the input body is detachably connected to the main body, the display unit is operable to rotate with respect to the input body, and the contact surface of the second contact portion is operable to engage with the first or second surfaces of the first contact portion by surface-to-surface contacting.

First claim

1 . An electronic device, comprising:
a main body that includes a display unit and a first contact portion rotatably connected to the display unit, wherein the first contact portion comprises a first surface and a second surface opposite to the first surface, and at least one part of the first contact portion has a thickness smaller than a thickness of the display unit; and an input body that is detachably connected to the main body and that includes a second contact portion with a contact surface, wherein, when the input body is connected to the main body, the display unit is configured to rotate with respect to the input body, and the contact surface of the second contact portion is configured to engage with the first or second surfaces of the first contact portion by surface-to-surface contact.

2 . The electronic device according to claim 1 , wherein, when the first contact portion is engaged with the second contact portion, a thickness of overlapping parts of the first and second contact portions is smaller than or equal to the thickness of the display unit.

3 . The electronic device according to claim 1 , wherein the first contact portion is connected to the display unit by a rotating connector.

4 . The electronic device according to claim 3 , wherein, in a direction perpendicular to a rotating axis of the rotating connector, the first contact portion has a length shorter than that of the display unit.

5 . The electronic device according to claim 1 , wherein, the first contact portion is configured to support the main body on a supporting platform when the input body is detached from the main body.

6 . The electronic device according to claim 1 , wherein, the input body is configured to support the electronic device on a supporting platform when the input body is assembled to the main body.

7 . The electronic device according to claim 6 , wherein, the input body is configured to rotate with respect to the main body from 0° to 360°.

8 . The electronic device according to claim 7 , wherein, when the input body is assembled to the main body, the input body is configured to rotate with respect to the main body at a predefined angle, so that the input body is lying on a supporting platform to support the electronic device, or an edge of the input body and an edge of the main body are contacting the supporting platform to support the electronic device.

9 . The electronic device according to claim 1 , wherein, a cross section of the first contact portion perpendicular to the rotating axis thereof is wedge-shaped.

10 . The electronic device according to claim 9 , wherein, the cross section of the second contact portion is wedge-shaped, the cross section of the second contact portion is a cross section cut in a direction perpendicular to a rotating axis of the first contact portion when the input body is assembled to the main body.

11 . The electronic device according to claim 10 , wherein the second contact portion is an edge portion of a housing of the input body.

12 . The electronic device according to claim 1 , further comprising a positioning hole formed on the first contact portion and a positioning projection formed on the second contact portion, the positioning projection is configured to insert into the positioning hole to fix the input body with the main body.

13 . The electronic device according to claim 12 , wherein, the positioning hole is formed as an elongated through-hole, and the positioning projection is formed into two positioning posts with adjustable spacing, the spacing between the two positioning posts is reduced so that the two positioning posts are configured to insert into the elongated through-hole, and the spacing is increased thereafter so that the two positioning posts are locked onto two ends of the elongated through-hole, respectively.

14 . The electronic device according to claim 13 , further comprising a spring attached to the positioning posts to automatically increase the spacing between the two positioning posts after the two positioning posts are inserted into the positioning hole.

15 . The electronic device according to claim 1 , wherein the main body is tablet computer.

16 . The electronic device according to claim 1 , wherein the input body is a keyboard.

17 . An electronic device having a main body that comprises:
a display unit; and a first contact portion coupled to the display unit and configured to rotate with respect to the display unit, wherein the first contact portion includes a first surface and a second surface opposite to the first surface, at least one part of the first contact portion has a thickness smaller than a thickness of the display unit; wherein the first or second surface of the first contact portion is configured to detachably engage with a contact surface of a second electronic device by surface-to-surface contacting and the first contact portion is configured to support the electronic device on a supporting platform.
