Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. It should also be noted that, in the embodiments of the present application, the features of the embodiments and the embodiments of the present application may be combined with each other to obtain new embodiments without conflict.

Embodiments of the present application provide a wireless power desk. The wireless power supply table can supply power for the notebook computer.

As shown in fig. 1, the wireless power table includes a table body 10 and a power base 20. The power supply base 20 is provided on the table body 10, and the notebook computer 100 may be provided on the power supply base 20. The power base 20 and the table body 10 may be fixed by friction only, for example, the power base 20 may be placed on the table body 10 without providing additional fixing means for fixing the power base 20 to the table body 10.

The table body 10 is used for realizing a wireless power supply table carrying function. The appearance of the table body 10 may be similar to that of a table in the related art, which is not limited in this application. As shown in fig. 2, in some embodiments, the table body 10 may include a table top 11 and a support portion 13, with the table top 11 being supported by the support portion 13. In some embodiments, the length of the support 13 may be adjustable to adjust the height of the table top 11 from the floor.

The table body 10 is provided with a wireless power transmitting terminal 12 that can be electrically connected to a power source. The power supply can provide electric energy for the wireless power supply table, and the wireless power supply table can convert the electric energy provided by the power supply into electric energy which can be used by the notebook computer 100 and transmit the electric energy to the notebook computer 100. The power source may be mains supply, a battery or a generator, etc., which is not limited in this application. The wireless power transmitting terminal 12 can convert electric energy into other forms of energy and transmit the energy, and the wireless power transmitting terminal 12 can be a coil structure.

As shown in fig. 3, the power supply base 20 is disposed on the table body 10. The power base 20 may be provided on the top surface 11 of the table body 10. The power supply base 20 can support the notebook computer 100 and be electrically connected with the notebook computer 100. The power supply base 20 is provided with a wireless power supply receiving end 21, and the wireless power supply receiving end 21 is electromagnetically coupled with the wireless power supply transmitting end 12 to receive the energy transmitted by the wireless power supply transmitting end 12 and convert the energy into electric energy. The wireless power receiving terminal 21 may be a coil structure.

In the related art, although there is a technology of wirelessly transmitting electric energy, a transmitting end and a receiving end are required for wirelessly transmitting electric energy, most of the notebook computers 100 on the market are powered by a wired mode, and the notebook computers 100 are not provided with the receiving end, and the notebook computers 100 have compact structures, and are difficult to be realized by additionally installing the receiving end in the notebook computers 100 with different brands and models.

Therefore, in the embodiment of the present application, by providing the power supply base 20 with the wireless power supply receiving end 21, the electric energy is transmitted to the power supply base 20 in a wireless transmission manner, and the power supply base 20 can be electrically connected with the notebook computer 100, so as to supply power to the notebook computer 100. The power supply base 20 may charge the battery of the notebook computer 100, or may directly supply the electric energy required for the operation of the notebook computer 100 without the battery.

The embodiment of the application provides a wireless power supply table, is provided with the power supply base 20 for notebook computer 100 power supply, realizes the wireless transmission of electric energy through electromagnetic coupling's mode between table body 10 and the power supply base 20, has avoided trompil on desktop 11, makes desktop 11 more pleasing to the eye, simultaneously, only needs comparatively succinct patch cord to realize the electricity between power supply base 20 and the notebook computer 100 and connects, has avoided desktop 11 disorder. In addition, when the wireless power supply table needs to supply power to the notebook computer 100, the power supply base 20 can be placed on the table body 10 to supply power to the notebook computer 100; when the notebook computer 100 is not required to be powered, the power supply base 20 can be removed from the table body 10, and the table body 10 of the wireless power supply table can be used as a common table.

In some embodiments, the wireless power transmitting terminal 12 and the wireless power receiving terminal 21 have the same resonance frequency, and the wireless power transmitting terminal 12 and the wireless power receiving terminal 21 perform power transmission through magnetic resonance.

It can be understood that most of the notebook computers 100 have a power of 50W-250W, and the wireless power supply method commonly used in the related art generally provides a voltage of 5V, a current of 0.2-3A, and a power of only 1-15W, which cannot meet the power supply requirement of the notebook computers 100. Therefore, in order to meet the power supply requirement of the notebook computer 100, in the present embodiment, wireless transmission of electric energy is performed by using a magnetic resonance method. The wireless transmission of electric energy is carried out by means of magnetic resonance, and 20-32V voltage and 5-10A current can be provided, so that 100-320W power is realized. At the same time, the magnetic resonance has a longer transmission distance, which facilitates the arrangement of the wireless power transmitting end 12 and the wireless power receiving end 21. Furthermore, the magnetic resonance has a certain divergence, which enables the wireless power supply to be realized without strict alignment of the wireless power supply transmitting end 12 and the wireless power supply receiving end 21, thereby making the wireless power supply more stable.

As shown in fig. 3 and 4, in some embodiments, the power base 20 includes a bottom plate 201 and a top plate 202.

The floor 201 is adapted to contact the table body 10. When the power supply base 20 is disposed on the table top 11, the soleplate 201 is in contact with the table top 11 of the table body 10 and is supported by the table top 11.

The top plate 202 is used to support the notebook computer 100. The top plate 202 is disposed opposite to the bottom plate 201, i.e., the top plate 202 and the bottom plate 201 form two opposite faces of the power supply base 20. A space capable of accommodating other components of the power supply base 20 is formed between the top plate 202 and the bottom plate 201. The wireless power supply receiving terminal 21 may be disposed in a space between the top plate 202 and the bottom plate 201.

In the present embodiment, the wireless power supply receiving terminal 21 is provided on the base plate 201. It will be appreciated that the distance between the base 201 and the table body 10 is shorter, and by disposing the wireless power receiving end 21 on the base 201, the distance between the wireless power receiving end 21 and the wireless power transmitting end 12 disposed on the table body 10 can be shortened, thereby reducing the consumption of wireless power transmission.

In some embodiments, the power supply base 20 further includes a magnetic shielding sheet 22, where the magnetic shielding sheet 22 is disposed on the top plate 202, and the magnetic shielding sheet 22 covers at least a portion of the surface of the top plate 202.

It can be understood that the wireless power supply transmits electric energy through the magnetic field, but some notebook computers 100 on the market have metal bottoms, and when the notebook computers 100 with metal bottoms are arranged on the power supply base 20, the magnetic field emitted from the wireless power supply transmitting end 12 to the wireless power supply receiving end 21 of the power supply base 20 may be absorbed by the bottom of the notebook computers 100 with metal bottoms, thereby reducing energy transmission efficiency. Therefore, in this embodiment, the magnetic isolation sheet 22 is disposed on the top plate 202, and the magnetic isolation sheet 22 can block the magnetic field generated by the wireless power supply transmitting end 12 from reaching the bottom of the notebook computer 100, thereby reducing energy loss, increasing energy transmission efficiency, and making wireless power supply more stable.

In some embodiments, the plane of top plate 202 intersects the plane of bottom plate 201, i.e., top plate 202 is disposed at an angle to bottom plate 201. Through this arrangement, when the power supply base 20 is disposed on the horizontal desktop 11, the top plate 202 can form a certain inclination angle, so that when the notebook computer 100 is disposed on the top plate 202, the keyboard and the display of the notebook computer 100 can also form a certain angle relative to the horizontal plane, and by reasonably setting the size of the included angle, the comfort level of the user when operating the notebook computer 100 can be increased.

As shown in fig. 4, in some embodiments, the top plate 202 is rotatably coupled to the bottom plate 201. It will be appreciated that the angle may be varied by different users, and that by rotatably coupling the top plate 202 to the bottom plate 201, the angle may be allowed to be adjusted by the user according to individual needs. In some embodiments, the top panel 202 may be hinged to an edge of the bottom panel 201, which may be the edge of the top panel 202 and/or bottom panel 201 that is closer to the user when the user operates the notebook computer 100. In some embodiments, one of the bottom plate 201 or the top plate 202 may form a connection portion extending from the edge toward the other of the bottom plate 201 or the top plate 202, the connection portion being hinged to the other of the bottom plate 201 or the top plate 202, the connection portion may allow sufficient space between the bottom plate 201 or the top plate 202 for accommodating other components of the power base 20.

In some embodiments, the power base 20 further includes a bracket 23 with a damped rotation shaft 231, the bracket 23 being rotatably connected to the top plate 202 and the bottom plate 201, respectively. In some embodiments, the bracket 23 may include a first connecting rod and a second connecting rod, where the first connecting rod and the second connecting rod form an included angle, one ends of the first connecting rod and the second connecting rod are hinged through a damping rotation shaft 231, and the other ends of the first connecting rod and the second connecting rod are hinged to the bottom plate 201 and the top plate 202, respectively. In other embodiments of the present application, the bracket 23 may include a greater number of connecting rods, which is not limited in this application.

By reasonably setting the damping of the damping rotation shaft 231, the damping rotation shaft 231 can support the weight of the notebook computer 100. In this embodiment, the relative positions of the top plate 202 and the bottom plate 201 are maintained by the bracket 23 with the damping rotation shaft 231, and the adjustment of the relative positions of the top plate 202 and the bottom plate 201 is realized by changing the shape of the bracket 23, so that the power supply base 20 can realize the above functions without providing a complex transmission mechanism, and the overall structure of the power supply base 20 is more compact.

In some embodiments, the power base 20 further includes a blower 24, the blower 24 being disposed on the top plate 202 and electrically connected to the wireless power receiving end 21; the blower 24 is used to blow air to the notebook computer 100 when the top plate 202 supports the notebook computer 100.

It can be understood that the notebook computer 100 generates heat during operation, and is limited by the volume thereof, and the heat dissipation capability of the notebook computer 100 is often poor, so in this embodiment, the power supply base 20 is further provided with a blower 24, and the blower 24 blows air to the notebook computer 100, so as to facilitate heat dissipation of the notebook computer 100.

As shown in fig. 4 and 5, in some embodiments, an annular sealing ring 25 is further disposed on one side of the top plate 202 for supporting the notebook computer 100, and the sealing ring 25 has a predetermined thickness, so that when the top plate 202 supports the notebook computer 100, the top plate 202, the bottom of the notebook computer 100, and the sealing ring 25 together form an air chamber for air flow. In some embodiments, the sealing ring 25 may be made of rubber to increase the friction between the notebook computer 100 and the sealing ring 25. In other embodiments of the present application, the sealing ring 25 may also be made of a material capable of being deformed greatly, such as a sponge, so as to adapt to the bottom of the notebook computer 100 with different shapes.

The top plate 202 is also provided with a blowing hole 2021, and the blowing member 24 is disposed at a position corresponding to the blowing hole 2021, so as to blow air into the air cavity through the blowing hole 2021.

It can be appreciated that in some embodiments of the present application, since the top plate 202 is provided with the magnetic isolation sheet 22, air cannot be blown to the notebook computer 100 through a large-area hole formed in the top plate 202, and most of notebook computers 100 on the market achieve heat dissipation through air outlet from the bottom air inlet side, in this embodiment, the top plate 202, the bottom of the notebook computer 100 and the sealing ring 25 together form an air cavity for air flow, meanwhile, the top plate 202 forms a blast port, the blast member 24 blows air into the air cavity through the blast port, and the air pressure in the air cavity is increased, so that air can enter the notebook computer 100 from the bottom of the notebook computer 100, and heat dissipation to the notebook computer 100 is achieved. In some embodiments, the tuyere may be provided away from the magnetism isolating sheet 22 to reduce an influence on the magnetism isolating effect of the magnetism isolating sheet 22.

In some embodiments, the power base 20 further includes a circumferential sidewall 203. The peripheral side walls 203 are connected to the edges of the top plate 202 and the bottom plate 201, respectively, and the top plate 202, the bottom plate 201, and the peripheral side walls 203 together form an enclosed space in which the blower 24 is disposed. The circumferential side wall 203 is capable of closing the gap between the corresponding edges of the top plate 202 and the bottom plate 201.

The power supply base 20 further includes air inlet holes 26, the air inlet holes 26 and the air blowing holes 2021 are respectively disposed near two opposite edges of the power supply base 20, and the air inlet holes 26 are used for introducing air into the enclosed space. The air inlet holes 26 and the air blowing holes 2021 are respectively disposed near two opposite edges of the power supply base 20, that is, the edge of the power supply base 20 where the air inlet holes 26 are closer and the edge of the power supply base 20 where the air blowing holes 2021 are closer are the opposite two edges of the power supply base 20.

For example, when a user normally uses the notebook computer 100 supported by the power supply base 20, the air inlet 26 may be provided at an edge of the power supply base 20 away from the user, e.g., the air inlet 26 may be provided on a rear circumferential side plate; and the air blowing holes 2021 may be provided at an edge of the power supply base 20 near the user, e.g., the air blowing holes 2021 may be provided near the edge of the top plate 202 near the user.

By this arrangement, air can flow from one side of the interior of the power supply base 20 to the opposite side of the interior of the power supply base 20 after entering the enclosed space through the air inlet 26, thereby achieving heat dissipation for components (such as the wireless power supply receiving end 21) in the interior of the power supply base 20.

In some embodiments, the air inlet holes 26 are provided with a filter screen 261, and the filter screen 261 can block dust in the air from entering the enclosed space. It can be appreciated that, since the top plate 202, the bottom plate 201 and the circumferential side wall 203 together form a closed space, air can only enter the interior of the power supply base 20 from the air inlet 26 and then flow through the interior of the notebook computer 100 after flowing through the interior of the power supply base 20, and therefore, the filter screen 261 is disposed at the air inlet 26, so that dust can be prevented from entering the interior of the power supply base 20 and the interior of the notebook computer 100, and the service lives of the power supply base 20 and the notebook computer 100 can be prolonged.

In some embodiments, the circumferential sidewall 203 is a flexible material. It will be appreciated that, since in some embodiments of the present application, top plate 202 is rotatably coupled to bottom plate 201, circumferential side wall 203 is provided of a flexible material in order to accommodate relative movement between top plate 202 and bottom plate 201 while forming an enclosed space. The flexible material may be natural or artificial leather, or some other polymer material, for example, which is not limited in this application. In some embodiments, the circumferential side wall 203 may be corrugated to create deformations that can accommodate different relative positions of the top plate 202 and the bottom plate 201.

As shown in fig. 6, in some embodiments, the bottom plate 201 includes a first protrusion 2011 extending from an edge of the bottom plate 201 toward the top plate 202, the air inlet 26 is disposed on the first protrusion 2011, or the top plate 202 includes a second protrusion (not shown) extending from an edge of the top plate 202 toward the bottom plate 201, and the air inlet 26 is disposed on the second protrusion.

It will be appreciated that, since in some embodiments of the present application, the circumferential side wall 203 is made of a flexible material, if the air inlet 26 is disposed on the circumferential side wall 203, the ventilation of the air inlet 26 may be affected when the circumferential side wall 203 is deformed. Therefore, in the present embodiment, the air inlet holes 26 are provided on the first protruding portion 2011 formed by the bottom plate 201 or the second protruding portion formed by the top plate 202, preventing the air inlet holes 26 from being affected by the deformation of the circumferential side wall 203. Of course, in other embodiments of the present application, for example, when the circumferential side wall 203 cannot be greatly deformed, the air inlet 26 may also be provided on the circumferential side wall 203.

As shown in fig. 7, in some embodiments, the power supply base 20 further includes a voltage and current stabilizing module 27, where the voltage and current stabilizing module 27 is electrically connected to the wireless power supply receiving end 21, and is used for stabilizing the voltage and current output by the wireless power supply receiving end 21. Since the frequency of the transmitted magnetic field has a certain fluctuation when the power is wirelessly transmitted, the current and the voltage generated by the wireless power receiving terminal 21 also have a certain fluctuation, which is difficult to be used by the notebook computer 100. Therefore, in the present embodiment, the voltage and the current output by the wireless power receiving terminal 21 are respectively stabilized by the voltage stabilizing module 27, so that the wireless power receiving terminal can be used by the notebook computer 100.

In some embodiments, the power supply base 20 further includes a multi-protocol fast charging module 28, and the multi-protocol fast charging module 28 is electrically connected to the voltage and current stabilizing module 27, so as to adjust the voltage and current output by the voltage and current stabilizing module 27, so as to realize power supply to the notebook computers 100 with different charging protocols. In order to increase universality of the wireless power desk, in this embodiment, the power supply base 20 is provided with the multi-protocol fast charging module 28, and the multi-protocol fast charging module 28 can be compatible with multiple charging protocols, and can adjust the voltage and current output by the voltage stabilizing and current stabilizing module 27, so that the power supply base 20 outputs multiple voltages and currents that can be used by the notebook computer 100.

In some embodiments, the power base 20 further includes an adjustment module that adjusts the output power of the power base 20 according to the power requirements of the notebook computer 100 by adjusting the multi-protocol fast charge module 28 to adjust the output power. For example, when the power consumption of the notebook computer 100 is low, or when the user performs high power consumption actions such as highlighting a screen, loading a web page, playing a computer game, etc., the power is increased to meet the power requirement of the notebook computer 100. When the power consumption of the notebook computer 100 is high, for example, the power consumption is more than 90%, or the screen brightness is reduced, and documents are processed, the power is reduced, so that the energy waste and the damage to the battery of the notebook computer 100 are avoided.

As shown in fig. 3, in some embodiments, the power base 20 further includes a power output 29, the power output 29 is electrically connected to the multi-protocol quick-charge module 28, and the power output 29 is electrically connected to the power interface 110 of the notebook computer 100. The power base 20 is supplied to the notebook computer 100 through the power output port 29. The power outlet 29 may be electrically connected to the power interface 110 of the notebook computer 100 through a patch cord, which may have various interfaces that may be alternatively mounted on the patch cord to accommodate different brands or different models of notebook computers 100.

In the embodiment of the present application, although the power is still transmitted between the notebook computer 100 and the power supply base 20 by a wired connection manner, the power supply base 20 and the notebook computer 100 can be electrically connected by a short patch cord due to the close distance between the power supply base 20 and the notebook computer 100; and the power supply base 20 itself has a function of adjusting current and voltage, and the power output by the power supply base 20 can be directly utilized by the notebook computer 100, so that the patch cord does not need to have a power adapter. Therefore, the patch cord is relatively compact, thereby achieving a tidy table top 11.

In some embodiments, the tabletop 11 has a receiving cavity formed therein, and the wireless power transmitting end 12 is disposed in the receiving cavity. By arranging the wireless power supply transmitting end 12 in the accommodating cavity in the tabletop 11, the whole wireless power supply table can be more concise. Of course, in other embodiments of the present application, the wireless power transmitting end 12 may also be disposed at the bottom of the desktop 11, so as to simplify the production and processing flow of the wireless power desk.

In some embodiments, the number of wireless power transmitters 12 is plural, and the plurality of wireless power transmitters 12 are disposed at different positions on the table top 11. Through setting up a plurality of wireless power supply transmitting ends 12 respectively in the different positions of desktop 11, can reduce the restriction of wireless power supply transmitting end 12's position to power supply base 20 setting position, make the position that power supply base 20 set up more nimble, in addition, to the desktop 11 that the area is great, can dispose a plurality of power supply base 20, a plurality of power supply base 20 set up respectively in a plurality of wireless power supply transmitting ends 12 corresponding positions to supply a plurality of users simultaneously to use.

In some embodiments, the area of the wireless power transmitting end 12 is larger than the area of the wireless power receiving end 21. By this arrangement, the position where the power supply base 20 is arranged can be made more flexible, and wireless power supply can be realized even if the center of the wireless power supply receiving end 21 deviates from the center of the wireless power supply transmitting end 12 by a certain distance.
