This patent application claims the benefit and priority of the co-pending Chinese Patent Application No. 201210374483.2, filed on Sep. 29, 2012, by Jun HUA et al., Attorney Docket Number P12838207, which is hereby incorporated by reference in its entirety.
Heat dissipation is one of the prime reasons for limiting the development of a flat electronic device (including a tablet, a flat mobile phone such as iPhone, etc.) during the design of the flat electronic device. The housing of such flat electronic device is usually designed to be sealed for reasons that there is a need to protect the interior electronic elements and prevent dust from entering, but which causes heat accumulation in the interior of the flat electronic device. In order to prevent decreasing the life of the electronic elements (even burning down) caused by the significant heat accumulated in the flat electronic device, the processing speed of the prime heat-dissipating element (such as processor, etc.) is usually reduced, which limits the performance of the flat electronic device.
Therefore, there is a need of providing a housing, a support, and a heat-dissipating assembly (or system) for a flat electronic device to solve the above problem in the conventional art.
In order to solving the above problem, a housing for a flat electronic device is provided by an embodiment in accordance with the present invention, wherein a heat-dissipating opening is disposed on a rear cover of the housing. The heat-dissipating opening is disposed in correspondence with a heat-generating means of the flat electronic device. A covering means is also disposed on the rear cover of the housing, and the covering means is configured to enable the heat-dissipating opening to be opened and closed.
Preferably, in an embodiment, the covering means is slidably disposed on the housing. The heat-dissipating opening is open when the covering means slides to a first position, and the heat-dissipating opening is closed when the covering means slides to a second position.

Various embodiments in accordance with the present invention relate generally to heat dissipation technology, in particular, to a housing, a support, and a heat-dissipating assembly (or system) for a flat electronic device (including a tablet, a flat mobile phone such as iPhone, etc.).
Plenty of specific details are presented in the description below so as to provide a more thorough understanding of the present invention. However, the present invention may be implemented without one or more of these details, as is evident to those skilled in the art. In other examples, some of the technical features known in the art are not described so as to avoid confusion with the present invention.
According to one embodiment of the invention, a housing 100 for the flat electronic device (hereinafter referred to as the housing 100) is provided, as shown in
To increase the convenience in use, in an embodiment, a covering means 103 may also be disposed on the rear cover 101 of the housing 100, and the covering means 103 is configured to enable the heat-dissipating opening 102 to be opened and closed.
Preferably, in an embodiment, a heat-conducting component (not shown) is disposed in the heat-dissipating opening 102. In an embodiment, when the covering means 103 covers the heat-dissipating opening 102, the heat-conducting component is located inside the covering means 103. The heat-conducting component is against the heat-generating means when the housing 100 is mounted on the flat electronic device, such that the heat generated by the heat-generating means may diffuse to the outside via the heat-conducting component through the heat-dissipating opening 102. The heat-conducting component may be made of a metal with higher thermal conductivity and may be in the shape of a plane or a mesh, etc. In this case, the heat-dissipating opening 102 may expose at least a part of the heat-conducting component. Besides being able to transfer the heat of the heat-generating means, the heat-conducting component may also, to some extent, act to protect the heat-generating means. In this way, the covering means 103 may be opened even in the case that a collision could easily happen, such as movement, etc., and thus, it reduces the limit of the performance of the flat electronic device due to the heat dissipation.
As an example, in an embodiment, the covering means 103 is slidably disposed on the housing 100. The heat-dissipating opening 102 is open when the covering means 103 slides to a first position A (referring to
Preferably, in an embodiment, at least a part of the covering means 103 may be disposed inside the rear cover 101 of the housing 100 to ensure that the outer surface of the housing 100 is smooth. According to a preferred embodiment of the invention, a sliding groove 104 is disposed on the inner surface of the rear cover 101 of the housing 100. The covering means 103 comprises a cover 103A and a switch 103B, and the cover 103A is slidably disposed in the sliding groove 104. The sliding groove 104 may surround the cover 103A as illustrated in
Further, in an embodiment, the covering means 103 further comprises a position-limiting component (not shown) which is used for limiting the position of the switch 103B when the cover 103A is in the first position A (the switch 103B is in an open position) and the second position B (the switch 103B is in a closed position), respectively. That is to say, there is a need to apply an external force to remove the switch 103B from the open position or the closed position. As an example, in an embodiment, the position-limiting component may be protrusions disposed nearby the open position and the closed position of the switch 103B. When removing the cover 103A from the first position A, the user need apply an external force to the switch 103B such that it is able to pass the protrusion nearby the open position and remove it from the open position. The protrusion at the closed position may have the same arrangement as that. Of course, the position-limiting component may also have other structures, as long as it can limit the switch 103B in the open and closed positions when the cover 103A is in the first and second positions A and B, respectively.
According to another embodiment of the invention, a support 200 for the flat electronic device (hereinafter referred to as the support 200) is provided, as shown in
As an example, in an embodiment, the heat-dissipating means 201 may be a fan. As an example, in an embodiment, the heat-dissipating means 201 may also be fins. Preferably, in an embodiment, the fins are projected over the supporting surface of the support 200 which is used for supporting the flat electronic device, as shown in
Further, in an embodiment, a power interface 202 may also be disposed on the support 200, through which the flat electronic device placed on the support 200 is able to be charged. The power interface 202 may be an USB-B type interface, a mini USB interface, or a micro USB interface, etc.
According to another embodiment of the invention, a heat-dissipating assembly or system for the flat electronic device (hereinafter referred to as the heat-dissipating assembly or system) is also provided. The heat-dissipating assembly comprises any housing and any support as mentioned above. A heat-dissipating opening is disposed on the rear cover of the housing and disposed in correspondence with the heat-generating means of the flat electronic device. A covering means is also disposed on the rear cover of the housing, and the covering means is configured to enable the heat-dissipating opening to be opened and closed. A heat-dissipating means is disposed on the support, and the support is used for supporting the flat electronic device. The position of the heat-dissipating means is corresponding to the position of the heat-dissipating opening when the flat electronic device is placed on the support. In an embodiment, each component contained in the heat-dissipating assembly (or system) may refer to the description of the respective part above.
In conclusion, the housing for a flat electronic device provided by various embodiments in accordance with the present invention enables the covering means to be operated according to the heat condition of the flat electronic device, and prevents significant heat accumulation in the flat electronic device, so as to solve the problems that exist in the conventional art where the accumulated heat limits the performance of the flat electronic device.
