1. Field of the Disclosure
The present disclosure generally relates to electronic devices, and particularly, to an electronic device having a main body and a cover pivotally assembled to the main body.
2. Description of Related Art
Electronic devices, such as laptops, usually includes a main body and a cover pivotally assembled to the main body. The main body includes a lock and a power switch. The cover is arranged with a hook corresponding to the lock. The power switch is used for powering on/off the electronic device.
When the main body and the cover are folded together, the hook is forced to disengage from the lock, and the cover may then be pivotably rotated from the main body. The power switch which may have been unreachable when the cover was folded to the main body can now be pressed by the user to power on the electronic device.
This is an inconvenience because several actions such as opening the cover and pressing down the power switch should be performed by the user before the electronic device can be powered up.
Therefore, a new and improved electronic device is desired to overcome the above-described shortcomings.
An electronic device comprising: a main body including a printed circuit board, a cover body pivotally assembled to the main body, and an active member. The cover body being selectively located in a closed position, at which the cover body covers the main body, and an open position at which the cover pivotally rotates away from the main body. The active member automatically power on the electronic device when the cover body is in the open position. The active member comprising: a first driving portion mounted to the cover body, a second driving portion mounted to the main body, a power switch mounted on the printed circuit board. When the cover body is in the closed position, an attraction force is generated by the cooperation of the first and second driving portion, and the power switch power off the electronic device. When the cover body rotates from the closed position to the open position, the attraction force activates the power switch to power on the electronic device.
Other systems, methods, features, and advantages of the present electronic device will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present apparatus, and be protected by the accompanying claims.
Many aspects of the present electronic device can be better understood with reference to the following drawings. The components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present device. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Reference will now be made to the drawings to describe the exemplary embodiments of the present electronic device, in detail.

The first driving portion 21 is disposed on a front edge of the inner surface 22 of the cover body 20, and opposite to the positioning post 121 of the main body 10 when the cover body 20 is located in the closed position.
The power switch 131 is disposed on the printed circuit board 13. The power switch 131 includes a first contact 133 and a second contact 135. The two contacts 133, 135 protrudes upwardly from the printed circuit board 13 and opposite to the positioning post 121.
The conductive member 14 is located above the first contact 133 and the second contact 135. The second driving portion 15 is secured with the conductive member 14 and is larger than the conductive member 14. The conductive portion 14 is capable of being driven to move together with the second driving portion 15. The conductive portion 14 selectively presses against the power switch 131 to control the power switch 131. When the conductive portion 14 presses against the power switch 131, the conductive portion 14 electrically connects the first contact 133 with the second contact 135, thus the power switch 131 is closed. As such, the associated power circuitry for supplying power to the electrical device 100 power on the electrical device 100. When the conductive portion 14 is not in contact with the power switch 131, the first contact 133 and the second contact 135 are not electrically connected to each other and the power switch 131 is opened. As such, the power circuitry associated with the power switch 131 is opened and no power is supplied to the electrical device 100.
The elastic member 17 is disposed between the second driving portion 15 and the first driving portion 21, and is sleeved around the positioning post 121. In the exemplary embodiment, the elastic member 17 is a compression spring. When the cover body 20 is in the closed position, the elastic member 17 is compressed by the attraction force between the second driving portion 15 and the first driving portion 21. When the cover body 20 rotates from the closed position to the open position, the first driving portion 21 moves away from the second driving portion 15 and the potential energy stored in the compressed elastic member 17 is released. This release of potential energy results in the elastic member 17 expanding along the longitudinal direction of the positioning post 121, which in turn pushes the second driving portion 15 and the conductive portion 14 to contact the first contact 133 and the second contact 135 of the power switch 131 thereby turning the electrical device 100 on. In other embodiment, the elastic member 17 may be an elastic gasket.
During assembly, the printed circuit board 13 is fixed on the first housing 11; the conductive portion 14 is fixed to the second driving portion 15; and the elastic member 17 is sleeved around the positioning post 121. Then, the conductive portion 14 and the second driving portion 15 are disposed between the elastic member 17 and the power switch 131, the conductive portion 14 is disposed adjacent to the power switch 131, and the second driving portion 15 is disposed at a side near the elastic member 17. Finally, the first driving portion 21 is fixed on the inner surface 22 of the cover 20, and the position of the second driving portion 15 is opposite to the position of the first driving portion 21.

As described above, when the electronic device 100 is in use, the electronic device 100 is automatically powered on. Therefore, it is very convenience for users.
