Patent Description:
With the development of modem science and technology, electronic products with multiple functions are increasingly favored by people. For example, a two-in-one computer is inspired by a notebook computer and a tablet computer in design and combines the advantages of the latter two. As has gradually been recognized by consumers, the two-in-one computer is suitable for both entertainment and office work due to its lightness, thinness, and portability, and it can be freely transformed into a notebook computer or a tablet computer in various occasions including an office, home, and an outdoor environment. A current two-in-one computer usually uses an air-cooled heat dissipation structure, which ensures heat dissipation performance of a product but brings problems of high noise and high energy consumption, and therefore affects user experience.

<CIT> describes a heat management apparatus for an electronic device that includes a heat spreader. The heat spreader has a top surface and a bottom surface. A first portion is coupled to the electronic device. A second portion extends away from the electronic device.

<CIT> provides an electronic device including two back covers. When one of the back covers is lifted to serve as a stand, the other back cover would be lifted simultaneously to form a gap through which heat generated by electronic elements is easily dissipated so as to enhance heat dissipation for the electronic device.

<CIT> describes a device kickstand that is rotatably attached to a mobile computing device. The kickstand can be rotated to various positions to provide support for different orientations of the computing device. Hinges are employed to attach the kickstand to the computing device.

<FIG> is a schematic diagram of a structure of an electronic device <NUM> according to an embodiment of this application. As an example instead of a limitation, in <FIG>, the electronic device <NUM> is a two-in-one computer, and includes a housing <NUM> and a display <NUM>, where the display <NUM> is disposed into the housing <NUM>, so that the electronic device <NUM> becomes a closed whole. In addition, the housing <NUM> and the display <NUM> jointly limit accommodation space in the electronic device <NUM>. The electronic device <NUM> further includes an electronic component (not shown in the figure) disposed in the accommodation space. The electronic component includes, but is not limited to, a circuit board, a processor, a sensor, a camera, a microphone, a battery, and the like.

The housing <NUM> may be a metal housing made of metals such as magnesium alloy or stainless steel. In addition, the housing <NUM> may alternatively be a plastic housing, a glass housing, a ceramic housing, or the like, but is not limited thereto.

The display <NUM> may be a light emitting diode (light emitting diode, LED) display, a liquid crystal display (liquid crystal display, LCD), an organic light-emitting diode (organic light-emitting diode, OLED) display, or the like, but is not limited thereto. The display <NUM> may alternatively be a flexible display that is foldable. In other words, the electronic device <NUM> may alternatively be a foldable electronic device, for example, a foldable tablet computer.

The electronic device <NUM> in embodiments of this application is a two-in-one computer. In other words, the electronic device <NUM> may be used as a common tablet computer or a notebook computer, to meet different use requirements. As shown in <FIG>, the electronic device <NUM> further includes a keyboard <NUM>. When the electronic device <NUM> is used as a notebook computer, the keyboard <NUM> may be connected to a processor in the housing <NUM> for communication, and can be used to enter instructions and data.

Optionally, the keyboard <NUM> is detachably connected to the housing <NUM>. When the electronic device <NUM> is used as a tablet computer, the keyboard <NUM> may be removed for convenience of a user.

Optionally, a touchpad may be further disposed on the keyboard <NUM>, so that user operation efficiency can be improved. Optionally, a card reader jack, a USB interface, a headset interface, and the like may be further disposed into a side wall of the keyboard <NUM> and/or the housing <NUM>, so that service performance of the electronic device <NUM> can be improved. Compared with a conventional two-in-one computer, the electronic device <NUM> provided by embodiments of this application enlarges a natural heat dissipation area to improve a heat dissipation capability. In this way, heat dissipation does not need to be performed in an air cooling manner, so that product performance can be improved.

<FIG> is a schematic cross-sectional view of an example of the electronic device <NUM> according to this application. As shown in <FIG>, the electronic device <NUM> provided by embodiments of this application further includes a pad-shaped cooling stand <NUM>, a heat emitting element <NUM>, and a flexible thermal pad <NUM>.

The pad-shaped cooling stand <NUM> is pivotally connected to the housing <NUM> through the rotating shaft, and is at least capable of remaining in a first position in a folded state and a second position (the position shown in <FIG>) in a standing state.

The heat emitting element <NUM> is disposed in accommodation space in the electronic device <NUM>.

The flexible thermal pad <NUM> is flexible and bendable. A first end of the flexible thermal pad <NUM> extends into the accommodation space in the electronic device <NUM> through a strip-shaped through hole disposed in the housing <NUM>. A second end (opposite to the first end) of the flexible thermal pad <NUM> is attached to the pad-shaped cooling stand <NUM>. Heat generated by the heating element <NUM> can be conducted to the pad-shaped cooling stand <NUM> through the flexible thermal pad <NUM>.

Specifically, the heat emitting element <NUM> is disposed in the accommodation space in the electronic device <NUM> in this application. The heat emitting element <NUM> can generate heat during operation, and may cause damage to the electronic device <NUM> when the heat accumulates to a specific extent. Therefore, the heat generated by the heat emitting element <NUM> needs to be dissipated to the outside of the housing <NUM> in time.

Optionally, the heat emitting element <NUM> may be a processor, for example, a central processing unit (central processing unit, CPU), a graphics processing unit (graphics processing unit, GPU), or the like.

Optionally, the heat emitting element <NUM> may alternatively be the display <NUM> or a driver of the display <NUM>. The display <NUM> or the driver of the display <NUM> also generates much heat after operating for a long time, and the heat needs to be dissipated in time as well.

Optionally, there may be more than one display <NUM>, that is, there may be a plurality of displays <NUM>. Therefore, attention should be paid to heat dissipation of an electronic device having a plurality of displays as well.

To dissipate heat of the heat emitting element <NUM>, the electronic device <NUM> in this application further includes the flexible thermal pad <NUM>. The first end of the flexible thermal pad <NUM> is disposed in the accommodation space in the electronic device <NUM>, and the second end opposite to the first end is attached to the pad-shaped cooling stand <NUM>. The flexible thermal pad <NUM> can conduct the heat generated by the heat emitting element <NUM> to the outside of the housing <NUM>, and dissipate the heat to an environment through the pad-shaped cooling stand <NUM>.

Optionally, the second end of the flexible thermal pad <NUM> is attached to the pad-shaped cooling stand through a thermally conductive adhesive, which can ensure that the second end is closely attached to the flexible thermal pad <NUM>, thereby improving heat conduction efficiency.

Optionally, as shown in <FIG>, a vapor module <NUM> may be disposed on the heat emitting element <NUM> to equalize heat. A first end of the flexible thermal pad <NUM> is attached to the vapor module <NUM>, and heat generated by the heat emitting element <NUM> is conducted to the flexible thermal pad <NUM> through the vapor module <NUM>, so that heat conduction efficiency can be improved.

Optionally, the vapor module <NUM> may be an apparatus with high thermal conductivity, for example, a heat pipe or a vapor chamber (vapor chamber, VC).

It is easy to understand that the flexible thermal pad <NUM> in this application has both high flexibility and high thermal conductivity, does not crack or break after being bent for a plurality of times, and therefore has high reliability. A material of the flexible thermal pad <NUM> is not limited in this application. Optionally, the flexible thermal pad <NUM> is any one or more of a flexible graphite sheet, a flexible thermal silicone sheet, a flexible composite sheet, or a flexible vapor chamber.

In addition, the size of the strip-shaped through hole for the flexible thermal pad <NUM> to extend through needs to match the flexible thermal pad <NUM> in width and thickness, and is not too large while ensuring that the flexible thermal pad <NUM> can extend through the strip-shaped through hole smoothly. Otherwise, dust outside the housing <NUM> may possibly enter the housing <NUM> through a gap between the flexible thermal pad <NUM> and a hole wall of the strip-shaped through hole, thereby damaging the electronic device <NUM>.

As shown in <FIG>, in this embodiment, the second end of the flexible thermal pad <NUM> is attached to an inner side of the pad-shaped cooling stand <NUM>, where the inner side is a side opposite to the housing when the pad-shaped cooling stand <NUM> is in the first position in the folded state, that is, a side that can be attached to an outer side of the housing <NUM>. The foregoing dispositions ensure heat conduction efficiency without affecting aesthetic appeal of the electronic device <NUM>, and make it not possible for a user to touch the flexible thermal pad <NUM>.

The pad-shaped cooling stand <NUM> in this application is shaped like a pad and has a large heat dissipation area and strong mechanical strength. The pad-shaped cooling stand <NUM> not only can support the housing <NUM>, but also has high heat dissipation performance, so that heat conducted by the flexible thermal pad <NUM> can be quickly dissipated to the environment.

Optionally, to improve heat dissipation performance and ensure enough mechanical strength, the pad-shaped cooling stand <NUM> may be a metal stand, for example, may be any one of a stainless steel stand, a copper stand, an aluminum alloy stand, a magnesium alloy stand, or the like.

The pad-shaped cooling stand <NUM> is pivotally connected to the housing <NUM> through the rotating shaft, and is at least capable of remaining in the first position in the folded state and the second position in the standing state.

When the electronic device <NUM> does not need to be supported (for example, the electronic device <NUM> is used as a tablet computer handheld by the user), the pad-shaped cooling stand <NUM> may be adjusted to the first position, that is, the pad-shaped cooling stand <NUM> is in the folded state. In this case, the pad-shaped cooling stand <NUM> may be attached to an outer side of the housing <NUM>, so that the user can carry and use the electronic device <NUM> in a handholding manner.

Optionally, to keep the pad-shaped cooling stand <NUM> in the first position (to keep it in the folded state), the pad-shaped cooling stand <NUM> may be configured as a metal stand (for example, a stainless steel stand), and a magnetic component (for example, a magnet, which is not shown in the figure) is disposed on the housing <NUM>. Thereby a magnetic force between the magnetic component and the metal stand is used to keep the pad-shaped cooling stand in the first position in the folded state.

Optionally, to keep the pad-shaped cooling stand <NUM> in the first position (to keep it in the folded state), a buckle (not shown in the figure) may be disposed on the pad-shaped cooling stand bracket, a slot that adapts to the buckle may be disposed in a corresponding position on the housing <NUM>, and the buckle and the slot fit each other to keep the pad-shaped cooling stand <NUM> in the first position in the folded state.

The electronic device <NUM> provided by embodiments of this application conducts heat generated by the heat emitting element <NUM> to the pad-shaped cooling stand <NUM> outside the housing <NUM> through the flexible thermal pad <NUM>, thereby enlarging a natural heat dissipation area of the electronic device <NUM> and improving heat dissipation performance of the electronic device <NUM>. No fan needs to be disposed in the electronic device <NUM> provided in embodiments of this application for heat dissipation, so that a noise problem caused by heat dissipation is avoided, and power consumption of the electronic device <NUM> is reduced. In addition, no fan disposition also facilitates a light and thin design of the electronic device <NUM>.

As shown in <FIG>, in this embodiment, no vapor module is disposed on the heat emitting element <NUM>, and a first end of the flexible thermal pad <NUM> is directly attached to the heat emitting element <NUM>. The foregoing dispositions facilitate a light and thin design of the electronic device <NUM>.

As shown in <FIG>, to enhance heat exchange, an enhanced cooling component <NUM> may be disposed on the pad-shaped cooling stand <NUM>. Further, the enhanced cooling component <NUM> may be detachably disposed on the pad-shaped cooling stand <NUM>, so that the enhanced cooling component <NUM> can be disposed on the pad-shaped cooling stand <NUM> when heat dissipation needs to be enhanced, and the enhanced cooling component <NUM> can be removed from the pad-shaped cooling stand <NUM> when heat exchange does not need to be enhanced, for the convenience of a user.

The enhanced cooling component <NUM> may be sold together with the electronic device <NUM> as an accessory of the latter, which improves product competitiveness.

Optionally, the enhanced cooling component <NUM> may be any one of a fin, a heat pipe, or a vapor chamber.

As shown in <FIG>, different from the foregoing embodiment, this embodiment replaces the pad-shaped cooling stand <NUM> in the foregoing embodiment with a stand <NUM>, and replaces the flexible thermal pad <NUM> in the foregoing embodiment with a highly thermal material layer <NUM>.

The stand <NUM> is connected to the keyboard <NUM>. The stand <NUM> is configured to support (or in other words, hold) the housing <NUM> (that is, configured to hold a main body of the electronic device <NUM>). The highly thermal material layer <NUM> is disposed on a support surface of the stand <NUM> that touches the housing <NUM>. The highly thermal material layer <NUM> can conduct heat from the housing <NUM> to the stand <NUM>, and dissipate the heat to a surrounding environment through the stand <NUM>.

Optionally, the highly thermal material layer <NUM> is further connected to the keyboard <NUM>, and can conduct heat to the keyboard <NUM>, which improves heat dissipation performance of the electronic device <NUM>.

Optionally, the highly thermal material layer <NUM> is further connected to a side surface other than the support surface of the stand <NUM>, and can conduct heat to another part of the stand <NUM>, which improves heat dissipation performance of the electronic device <NUM>.

Optionally, the stand <NUM> is a metal stand, so that a heat dissipation effect can be improved.

Optionally, the highly thermal material layer <NUM> is at least one of a thermal metal layer, a thermal silicone layer, a thermal film, a graphite layer, and the like.
