Description

Electronic devices

The present disclosure relates to an electronic device, and in particular to an electronic device having a supporting structure.

For laptops, heat dissipation has a huge impact on performance. If the laptop is overheated for a long time, it will not only cause performance degradation, but also easily damage the electronic components inside the laptop. Since most electronic components are located at the bottom of the body, in recent years, in order to avoid the user's hands from being exposed to heat for a long time due to the air inlet and outlet on the side, there has been an improvement in the method of using air inlets and outlets facing the bottom to dissipate heat.

However, this heat dissipation method requires that the bottom of the computer be kept at a proper distance from the desktop to avoid airflow obstruction and affect heat dissipation efficiency. The foot pads of existing laptops are mostly fixed in height, and in order to meet the requirements of a thin and light appearance, the height of the foot pads is mostly controlled below 5mm.

However, using a lower height footrest will also result in poor airflow due to limited airflow space, affecting heat dissipation performance. Although there are additional height-increasing stands on the market, users need to carry an extra stand when going out, which goes against the original purpose of reducing the weight and thickness of the laptop and making it thinner, and adds more burden to users.

In view of the above, the present disclosure provides, in one embodiment, an electronic device including a main body and a supporting structure. The main body includes a first electromagnetic coil and a second electromagnetic coil disposed adjacent to each other. The supporting structure is pivoted to the main body via a pivot axis, and has a first side and a second side connected to each other, and an angle is formed between the first side and the second side. The supporting structure includes a first magnet and a second magnet. The first magnet is disposed on the first side and corresponds to the first electromagnetic coil. The second magnet is disposed on the second side and corresponds to the second electromagnetic coil, and the pivot axis is located between the first magnet and the second magnet. When the second electromagnetic coil faces the second magnet, the magnetic pole generated is different from the second magnet, and the second side of the support structure contacts the main body. When the first electromagnetic coil faces the first magnet, the magnetic pole generated is different from the first magnet, and the support structure rotates around the pivot axis, and the first side of the support structure contacts the main body, and the second side is away from the main body.

Thus, the electronic device disclosed in the present invention can allow the support structure to rotate away from the main body by changing the magnetic poles of the first electromagnetic coil and the second electromagnetic coil, thereby raising the main body of the electronic device. In this way, the bottom of the main body of the electronic device can be away from the desktop, thereby increasing the heat dissipation space and improving the heat dissipation efficiency. When the electronic device is not in use or needs to be carried around, the support structure can be rotated back to be stored at the bottom of the main body for easy carrying.

The following embodiments are presented for detailed description, however, the embodiments are only used as examples and do not limit the scope of the present disclosure. In addition, some elements are omitted in the drawings in the embodiments to clearly show the technical features of the present disclosure. The same reference numerals will be used to represent the same or similar elements in all drawings.

FIG. 1 is a schematic diagram of a partially cut-away side view of the support structure of the electronic device of the first embodiment of the present disclosure when the support structure is stored. FIG. 2 is a schematic diagram of a partially cut-away side view of the electronic device of the first embodiment of the present disclosure when the support structure is rotated out of the support. As can be seen from FIG. 1 and FIG. 2, the electronic device 100 of the present embodiment includes a main body 10 and a support structure 20. The electronic device 100 can be, for example, a laptop or other portable electronic device, and the main body 10 is the host part of the laptop.

The main body 10 includes a first electromagnetic coil 11 and a second electromagnetic coil 12 which are arranged adjacent to each other. The first electromagnetic coil 11 and the second electromagnetic coil 12 can be arranged at any position of the main body 10. In this embodiment, the first electromagnetic coil 11 and the second electromagnetic coil 12 are arranged at the bottom of the accommodation space S of the main body 10 as an example. The support structure 20 is pivoted to the main body 10 via a pivot 21 and has a first side 201, a second side 202, a third side 203 and a fourth side 204 which are connected in sequence. An angle A is formed between the first side 201 and the second side 202. The support structure 20 includes a first magnet 23 and a second magnet 24. The first magnet 23 is arranged on the first side 201 of the support structure 20 and corresponds to the first electromagnetic coil 11. The second magnet 24 is disposed on the second side 202 of the supporting structure 20 and corresponds to the second electromagnetic coil 12.

As shown in FIG1 , when the magnetic pole generated by the second electromagnetic coil 12 facing the second magnet 24 is different from the second magnet 24, the second electromagnetic coil 12 attracts the second magnet 24, so that the second side 202 of the supporting structure 20 contacts the main body 10. In this embodiment, the first magnet 23 facing the main body 10 is the N pole, and the second magnet 24 facing the main body 10 is the S pole, but it is not limited to this, as long as the two magnetic poles are different. In one embodiment, the second electromagnetic coil 12 is passed through a current as shown by the arrow in FIG1 , so that the second electromagnetic coil 12 generates a magnetic pole with an S pole on the top and an N pole on the bottom. At this time, since the second electromagnetic coil 12 is facing the second magnet 24 with the N pole, which is different from the S pole of the second magnet 24 facing the main body 10, the two will produce an attraction effect. Therefore, the second side 202 of the support structure 20 will contact the main body 10 under the force of attraction. At this time, the electronic device 100 is in the normal mode under the storage state of the support structure 20, and can be easily moved and carried.

In the normal mode, the first electromagnetic coil 11 can remain non-conductive or provide a current in the direction indicated by the arrow in FIG. 1 , which will be described in detail later.

When the support structure 20 is required to support the electronic device 100 for heat dissipation, the current shown by the arrow in FIG. 2 (opposite to FIG. 1 ) can be provided to the first electromagnetic coil 11. At this time, since the magnetic pole generated by the first electromagnetic coil 11 facing the first magnet 23 is different from the first magnet 23, the support structure 20 rotates around the pivot 21, so that the first side 201 of the support structure 20 contacts the main body 10, and the second side 202 is away from the main body 10. Please refer to FIG. 2 , the first electromagnetic coil 11 is passed through the current shown in FIG. 2 , so that the first electromagnetic coil 11 generates a magnetic pole with an N pole at the top and an S pole at the bottom. At this time, since the first electromagnetic coil 11 is facing the first magnet 23 with the S pole, which is different from the N pole of the first magnet 23 facing the main body 10, the two will produce an attraction effect. Therefore, the first side 201 of the support structure 20 will contact the main body 10 under the force of attraction, and the second side 202 will be away from the main body 10 and press against the plane (such as a desktop) where the electronic device 100 is placed, producing a push-up effect, so that the electronic device 100 is lifted. At this time, the electronic device 100 is in a high-performance mode under the support structure 20, and the bottom of the main body 10 of the electronic device 100 can be far away from the plane where it is placed, increasing the heat dissipation space and improving the heat dissipation efficiency.

In addition, in this embodiment, as can be seen from FIG. 1 and FIG. 2 , the hinge 21 is disposed on the second side 202 of the supporting structure 20. Thus, when the supporting structure 20 is intended to support the electronic device 100 for heat dissipation, when the first side 201 of the supporting structure 20 contacts the main body 10, part of the second side 202 can also contact the main body 10, thereby providing a more stable support.

In the high-performance mode, the second electromagnetic coil 12 can remain non-conductive or provide a current in the direction shown in FIG. 2 , which will be described in detail later.

In addition, the current direction provided above can be changed by, for example, a connected circuit to change the power supply direction, which will not be described in detail here. In this way, the electronic device 100 of this embodiment can generate a magnetic pole in a desired state by changing the current passing through the first electromagnetic coil 11 and the second electromagnetic coil 12, so that the support structure 20 can rotate away from the main body 10 and lift the main body of the electronic device 100. In this way, the bottom of the main body 10 of the electronic device 100 can be far away from the placement plane, thereby increasing the heat dissipation space and improving the heat dissipation efficiency. When the electronic device 100 is not in use or is to be carried and moved, the support structure 20 can be rotated back to be stored at the bottom of the main body 10 to facilitate moving and carrying.

As shown in FIG. 1 and FIG. 2 , the angle A between the first side 201 and the second side 202 of the support structure 20 is a blunt angle. The blunt angle can be between 120 degrees and 150 degrees. When the angle A is a blunt angle, the first magnet 23 and the second magnet 24 can maintain a relatively appropriate distance from the first electromagnetic coil 11 and the second electromagnetic coil 12, so that the force generated by them can be sufficient to rotate the support structure 20, thereby lifting the electronic device 100 or retracting the bottom of the electronic device 100.

Furthermore, in the normal mode, when the second electromagnetic coil 12 faces the second magnet 24, the magnetic pole generated is different from the second magnet 24, and the magnetic pole generated by the first electromagnetic coil 11 facing the first magnet 23 is the same as the first magnet 23. That is, as shown in FIG1, the first electromagnetic coil 11 is passed through the current shown in FIG1, which will cause the first electromagnetic coil 11 to generate a magnetic pole with an S pole at the top and an N pole at the bottom. The first electromagnetic coil 11 faces the first magnet 23 with an N pole, which is the same as the magnetic pole of the first magnet 23, so the two will produce a repulsive effect. Due to the attraction between the second electromagnetic coil 12 and the second magnet 24 and the repulsion between the first electromagnetic coil 11 and the first magnet 23, the second side 202 of the supporting structure 20 can be brought into closer contact with the main body 10.

Similarly, in the high-performance mode, when the first electromagnetic coil 11 faces the first magnet 23, the magnetic pole generated is different from the first magnet 23, and the magnetic pole generated by the second electromagnetic coil 12 facing the second magnet 24 is the same as the second magnet 24. That is, as shown in FIG2, the second electromagnetic coil 12 is passed through the current shown in FIG2, which will cause the second electromagnetic coil 12 to generate a magnetic pole with an N pole on the top and an S pole on the bottom. The second electromagnetic coil 12 faces the second magnet 24 with an S pole, which is the same as the magnetic pole of the second magnet 24, so the two will produce a repulsive effect. Due to the attraction between the first electromagnetic coil 11 and the first magnet 23 and the repulsion between the second electromagnetic coil 12 and the second magnet 24, the first side 201 of the supporting structure 20 can be brought into closer contact with the main body 10, while the second side 202 of the supporting structure 20 is pushed outward to provide better supporting force.

Next, please refer to Figures 3 and 4 simultaneously. Figure 3 is a partially cut-away side view schematic diagram of the support structure of the electronic device of the second embodiment of the present disclosure when it is stored, and Figure 4 is a partially cut-away side view schematic diagram of the support structure of the electronic device of the second embodiment of the present disclosure when it is rotated out of the support. In this embodiment, the same components as those in the first embodiment will be represented by the same component symbols, and these components and related connection relationships will not be repeated.

As shown in FIG3 , the pivot shaft 21 may also be disposed at the intersection (i.e., at the angle A) of the first side 201 and the second side 202 of the support structure 20, and need not be located at the second side 202. The first electromagnetic coil 11 and the second electromagnetic coil 12 are electrically connected, and the first electromagnetic coil 11 is directed toward the first magnet 23 and the second electromagnetic coil 12 is directed toward the second magnet 24 to simultaneously generate the same magnetic pole. By the connection method shown in FIG3 , as long as the direction of the current conduction is changed, the first electromagnetic coil 11 and the second electromagnetic coil 12 can be simultaneously conducted to generate the required magnetic pole, without the need to provide the required current to the first electromagnetic coil 11 and the second electromagnetic coil 12 separately. For example, in the normal mode, the current direction is provided as shown by the arrow in FIG3, so that the first electromagnetic coil 11 and the second electromagnetic coil 12 generate magnetic poles with both N poles at the bottom. In the high-performance mode, the current direction is provided as shown by the arrow in FIG4, so that the first electromagnetic coil 11 and the second electromagnetic coil 12 generate magnetic poles with both S poles at the bottom.

Furthermore, in this embodiment, the electronic device 100 further includes a shaft 30, a cover 40, a third magnet 50, and a magnetically actuated switch 60. The cover 40 is pivotally connected to the main body 10 via the shaft 30 and is located on a side relative to the support structure 20. The third magnet 50 is connected to the shaft 30. The magnetically actuated switch 60 is accommodated in the main body 10 and electrically connected to the first electromagnetic coil 11 and the second electromagnetic coil 12. When the cover 40 rotates away from the main body 10 to a specific angle from the position where it covers the main body 10, the cover 40 drives the shaft 30 to rotate to the third magnet 50 corresponding to the magnetically actuated switch 60, causing the magnetically actuated switch 60 to be turned on, so that the first electromagnetic coil 11 and the second electromagnetic coil 12 are both turned on to generate magnetic poles. At this time, the current in the required direction can be provided to the first electromagnetic coil 11 and the second electromagnetic coil 12 depending on whether the user selects the normal mode or the high-performance mode.

In this embodiment, the first electromagnetic coil 11 and the second electromagnetic coil 12 can generate magnetic poles only when the user uses the electronic device 100 (that is, when the cover 40 is opened) by the action of the magnetically activated switch 60. The specific angle at which the cover 40 rotates away from the main body 10 can be set to 80 to 130 degrees, and the length of the third magnet 50 is sufficient to correspond to the magnetically activated switch 60 within the specific angle range.

In this embodiment, as shown in FIG. 3 and FIG. 4 , the electronic device 100 further includes an extended metal member 70 connected between the rotating shaft 30 and the third magnet 50. In this embodiment, the extended metal member 70 extends in a direction away from the cover 40 and rotates under the drive of the rotating shaft 30. The third magnet 50 is disposed at one end of the extended metal member 70 away from the rotating shaft 30. By disposing the extended metal member 70, the third magnet 50 can be closer to the magnetically actuated switch 60, so that it can more surely generate a force on the magnetically actuated switch 60. At the same time, a third magnet 50 with weaker magnetism can also be used to prevent the third magnet 50 from affecting other electronic components.

In addition, the fourth side 204 can be arranged parallel to the second side 202, or the third side 203 can be arranged parallel to the first side 201. In this embodiment, the third side 203 is arranged parallel to the first side 201, and the fourth side 204 is arranged parallel to the second side 202. In this way, the contact area between the third side 203 and the plane on which it is placed can be enlarged, providing better support force.

Next, please refer to FIG. 5 and FIG. 6 simultaneously. FIG. 5 is a schematic diagram of the circuit of the electronic device of the third embodiment of the present disclosure in the normal mode, and FIG. 6 is a schematic diagram of the circuit of the electronic device of the third embodiment of the present disclosure in the high-performance mode. In this embodiment, the same components as those of the second embodiment will be represented by the same component symbols, and these components and related connection relationships will not be repeated. This embodiment can be applied to the structure shown in the second embodiment. When the direction of the current provided to the first electromagnetic coil 11 and the second electromagnetic coil 12 is to be changed, it is not necessary to change the direction of the current provided, but to change the direction of the current provided by conducting different loops.

FIG5 is a normal mode, in which the direction of the current provided to the first electromagnetic coil 11 and the second electromagnetic coil 12 will cause the first electromagnetic coil 11 and the second electromagnetic coil 12 to generate magnetic poles with both N poles at the bottom. FIG6 is a high-performance mode, in which the direction of the current provided to the first electromagnetic coil 11 and the second electromagnetic coil 12 will cause the first electromagnetic coil 11 and the second electromagnetic coil 12 to generate magnetic poles with both S poles at the bottom. This switching method can be manually controlled by the user by setting a physical switching switch or using a circuit switching switch to switch according to needs.
