Technical Field

[0001] This invention belongs to the field of wireless charging technology, and specifically relates to a wireless charging stand. Background Technology

[0002] Wireless charging works on the same basic principle as a transformer: the 'electricity generates magnetism, and magnetism generates electricity' principle learned in high school physics. Taking a mobile phone as an example, the charger contains a magnetic core with a coil wound around it, which converts electricity into an electromagnetic field. This electromagnetic field can propagate through space. Meanwhile, the phone also has a corresponding receiving coil. When this receiving coil comes into contact with the electromagnetic field emitted by the charger, it is processed by a certain circuit to charge the phone.

[0003] Currently, the device for wireless charging mobile phones is a wireless charging stand, which includes a container, components inside the container for wireless charging of mobile phones, and a support platform integrated into the upper wall of the container. By placing the mobile phone on the support platform, wireless charging can be performed.

[0014] Preferably, the cooling component 4 includes two pairs of annular channels 10. The annular channels 10 are formed by a pair of annular channels connected by flanges.

[0015] Preferably, the positioning component 5 includes a box 31, which is fixed to the lower wall of the cover 21. The upper wall of the box 31 is connected to the operating chamber 23 via an annular columnar air guide channel 32. A gate 3 is fixedly connected to the air guide channel 32. Three annular columnar air supply channels 33 and one air supply channel 33 are fixedly connected to the tail and head of the box 31, respectively. Insulating rock wool blocks 34 are screwed to the upper walls of the two pairs of cuboid components 7. Insulating rock wool sheets 35 are provided in the two pairs of insulating rock wool blocks 34. The insulating rock wool sheets 35 protrude from one side of the insulating rock wool blocks 34. The other side of the two pairs of insulating rock wool blocks 34 is fixedly connected to an air supply channel 36 and has an opening 38. The opening 38 is located in the air supply channel 36.

The annular columnar member 43 is located on the outer surface of the cover 21 and is formed by a pair of annular columnar channels connected by flanges. One end of the lower block 39 is connected to an air supply channel 44 equipped with a gate valve. An air supply channel 41 communicates between the lower block 39 and the passage 42, and a gate valve 5 is installed on the air supply channel 41.

[0018] The beneficial effects of this invention are as follows:

[0019] By changing the lateral span of the load-bearing components, the size of the area enclosed by the two pairs of support mechanisms is changed. Then, a pair of interlocking pieces 51 on the adjacent cuboid 7 are inserted into a pair of interlocking holes 54 on an L-shaped platform 2, positioning the two L-shaped platforms 2 at the lower bend of the cuboid shape enclosed by the two pairs of load-bearing components 3. This improves the stability between the two pairs of load-bearing components 3. Next, the phone is placed on the upper wall of the two pairs of load-bearing components 3, allowing the load-bearing components 3 to accommodate phones of different sizes, thus improving compatibility. During storage, the cuboid 7... Separating from the L-shaped platform 2, the tension screw 49 is disassembled. The motion frame 8 is then retracted into the cuboid component 7 to reduce the size of the load-bearing component 3. Next, the arch-shaped component 9 is rotated around the roller 48 to close, achieving the closure of the two pairs of load-bearing components 3, facilitating their relocation and storage. The motor of the cooling component drives the vanes in operating chamber one to rotate, causing the refrigerant in the two pairs of L-shaped platforms to surge. Simultaneously, the motor drives the vanes in operating chamber two to rotate, along with the semiconductor cooler, ensuring continuous heat transfer between the refrigerant and the lower wall of the phone, thus cooling the phone and ensuring its smooth operation. During cooling, the air in operating chamber two reaches the box, and then continues to reach the insulating rock wool sheet, thereby driving the insulation... The rock wool sheets move inward to clamp the phone, improving its stability. During cooling, air from the lower block reaches passage two, creating a pressure lower than the external atmospheric pressure within the lower block. This allows the lower block to adhere firmly to the upper wall of the container, improving the stability of the L-shaped platform and thus the phone's mounting. When removing the phone, the gate on air supply passage four is opened, allowing external air to enter the lower block, facilitating separation from the upper wall of the container. The cuboid component and L-shaped platform can disassemble, and the two pairs of support mechanisms can close. Simultaneously, both pairs of L-shaped platforms and cooling components can disassemble, as can the two pairs of positioning components and two pairs of securing components, facilitating relocation and storage. This effectively avoids the shortcomings of existing wireless charging stands, which can only support one type of phone, have poor compatibility, and limited performance. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figures 1-12 As shown, the wireless charging stand includes:

[0034] The container, components disposed inside the container for wirelessly charging a mobile phone, and a support platform for connecting to the upper wall of the container; the wireless charging components include an induction circuit board and a coil for wireless charging.

[0035] The support platform includes two pairs of hollow L-shaped platforms 2. Two pairs of support components 3 are provided on the upper wall of each L-shaped platform 2. Each L-shaped platform 2 is located on the lower wall of one end of a pair of support components 3. A cooling component 4 is provided between the two pairs of L-shaped platforms 2. A positioning component 5 is provided on the upper wall of each pair of support components 3. A fastening component 6 is provided on the lower wall of each pair of L-shaped platforms 2.

[0036] The load-bearing component 3 includes a hollow cuboid component 7, in which a pair of motion frames 8 are disposed. One end of each pair of motion frames 8 is fixedly connected to an arch-shaped component 9. The pair of arch-shaped components 9 are respectively disposed at both ends of the cuboid component 7 and are in contact with the cuboid component 7.

[0037] The motion frame 8 has a strip groove 58 on one side, and the cuboid 7 has several through holes 45 in the strip groove 58. The through holes 45 are located in the strip groove 58. One side of the cuboid 7 is screwed to a pressure plate 46, and the pressure plate 46 has several cable outlet holes 57. Both sides of the upper wall of the cuboid 7 are screwed to tension screws 50, and one end of the tension screw 50 is attached to the upper wall of the motion frame 8. The through holes 45, the strip groove 58, and the cable outlet holes 57 facilitate the passage of cables such as headphone wires from mobile phones. In addition, the mobile phone cables can be contained within the cuboid 7, improving the appearance.

[0038] A pair of guide channels 52 are formed on the lower wall of the cuboid component 7. A guide plate 53 is fixedly connected to the lower wall of the motion frame 8. The guide plate 53 is movably disposed in the guide channel 52. When the motion frame 8 moves, it pulls the guide plate 53 to run along the guide channel 52, so as to prevent the motion frame 8 and the cuboid component 7 from separating.

[0039] A transition strip 47 is provided between adjacent pairs of arch-shaped components 9. Three of the transition strips 47 are movably connected at both ends to the arch-shaped components 9 at their respective ends via rollers 48. One end of another transition strip 47 is movably connected to the arch-shaped component 9 at its other end via rollers 48. The other end of the transition strip 47 is threaded to the arch-shaped component 9 at its other end via a tensioning screw 49, which facilitates the closure and containment of the two pairs of cuboid components 7.

[0040] The lower wall of the cuboid 7 is fixed with two insert pieces 51 on both sides. The upper wall of the L-shaped platform 2 has a pair of insert holes 54. The pair of close insert pieces 51 on the adjacent pair of cuboid 7 are respectively inserted into the pair of insert holes 54 on the upper wall of the L-shaped platform 2. The pair of insert pieces 51 on the adjacent cuboid 7 are inserted into the pair of insert holes 54 on the L-shaped platform 2, so that the two pairs of L-shaped platforms 2 are located at the lower bending position of the cuboid shape formed by the two pairs of bearing components 3, thereby improving the reliability between the two pairs of bearing components 3.

[0041] In this way, unscrewing the tension screw 50 releases the connection between the cuboid 7 and the motion frame 8. Then, the motion frame 8 can be dragged outwards from the cuboid 7 to the appropriate position. Next, tighten the tension screw 50 to secure the connection between the cuboid 7 and the motion frame 8, thus changing the lateral span of the load-bearing components 3. This allows for changing the size of the area enclosed by the two pairs of load-bearing components 3. Then, insert a pair of interlocking pieces 51 on the adjacent cuboid 7 into a pair of interlocking holes 54 on an L-shaped platform 2, positioning the two L-shaped platforms 2 at the lower bend of the cuboid shape enclosed by the two pairs of load-bearing components 3, improving the stability between the two pairs of load-bearing components 3. Then, place the mobile phone on the upper wall of the two pairs of load-bearing components 3, allowing the load-bearing components 3 to accommodate mobile phones of different sizes, improving compatibility. During storage, the cuboid 7 and the L-shaped platform 2... Separate, then disassemble the tension screw 49, then retract the motion frame 8 into the cuboid part 7 to reduce the size of the load-bearing component 3, then rotate the arch-shaped part 9 around the roller 48 to close it, achieving the closure of the two pairs of load-bearing components 3, which facilitates the relocation and storage of the load-bearing components 3.

[0042] The cooling component 4 includes two pairs of annular channels 10. The annular channels 10 are formed by a pair of annular channels connected by flanges. The two pairs of annular channels 10 are located between two pairs of L-shaped platforms 2, which are connected via the two pairs of annular channels 10. A cover 21 is fixedly connected to one of the annular channels 10. The cover 21 is located on the lower wall of the two pairs of cuboid components 7. The cover 21 is divided into an operating chamber 1 23 and an operating chamber 24 by a baffle 22. The annular channels 10 and the operating chamber 1 23 are connected. A motor 25 is fixedly connected to the operating chamber 24. A rotating vane 26 is fixedly connected to the rotor of the motor 25. A pair of rotating vanes 26 are respectively located in the operating chamber 1 23 and the operating chamber 24. One side of the cover 21 is fixedly connected to... A first cylindrical passage 27 is located on one side of a first cylindrical channel 10 and communicates with a second operating chamber 24. The first cylindrical passage 27 is fixed inside an L-shaped platform 2. An assembly frame 28 is fixed to one side wall of the L-shaped platform 2. A semiconductor cooler 29 and an aluminum alloy fin 30 are fixed inside the assembly frame 28. The aluminum alloy fin 30 is located on one side of the semiconductor cooler 29 and inside the L-shaped platform 2. The first cylindrical passage 27 is located on one side of the assembly frame 28. The lower part of the first cylindrical passage 27 communicates with a second cylindrical passage 42 on which a first gate is mounted. The lower part of the second cylindrical passage 42 is fixed to a sieve plate with several sieve holes. The tail of the L-shaped platform 2 on which the assembly frame 28 is mounted is fixed to a second cylindrical channel 55. A second gate is mounted on the second cylindrical channel 55.

[0043] Thus, after the phone is placed on the two pairs of support components 3, the cooling component 4 is located on the lower wall of the phone. Refrigerant is injected into the two connected L-shaped platforms 2 through the annular cylindrical channel 2 55. Then, the power supply batteries of the motor 25 and the semiconductor cooler 29 are turned on, and the motor and the semiconductor cooler are made to run. The motor 25 drives the rotating vane 26 to rotate. The rotating vane 26 in the operating chamber 23 The rotating traction pulls the surrounding refrigerant to rotate, causing the refrigerant in the two pairs of L-shaped platforms 2 to surge. The rotating vane 26 in the second operating chamber 24 pulls the surrounding air to surge, allowing the outside air to reach the first channel 27 through the second passage 42, and then send away the heat from the heat dissipation end of the semiconductor cooler 29 and into the second operating chamber 24. The heat absorption end of the semiconductor cooler 29 is heat transferred through the aluminum alloy fins 30 and the refrigerant in the L-shaped platform 2, which facilitates heat transfer between the refrigerant and the lower wall of the mobile phone, thereby facilitating the cooling of the mobile phone and its smooth operation. In addition, because the annular columnar channel 10 can be decomposed, the two pairs of L-shaped platforms 2 can be decomposed, which facilitates the relocation and storage of the cooling component 4 and the L-shaped platform 2.

[0044] The positioning component 5 includes a box 31, which is fixed to the lower wall of the cover 21. The upper wall of the box 31 is connected to the operating chamber 23 via an annular columnar air guide channel 32. A gate 3 is fixedly connected to the air guide channel 32. Three annular columnar air supply channels 33 and one air supply channel 33 are fixedly connected to the tail and head of the box 31, respectively. Insulating rock wool blocks 34 are screwed to the upper walls of the two pairs of cuboid parts 7. Insulating rock wool sheets 35 are provided in the two pairs of insulating rock wool blocks 34. The insulating rock wool sheets 35 protrude from one side of the insulating rock wool blocks 34. The other side of the two pairs of insulating rock wool blocks 34 is fixedly connected to an air supply channel 36 and has an opening 38. The opening 38 is located on one side of the air supply channel 36. The two pairs of air supply channels 36 and the two pairs of air supply channels 33 are connected by an annular columnar plastic channel 37 via flanges.

[0045] One end of the insulating rock wool sheet 35 is embedded with a sealing rod 56, which is located inside the insulating rock wool block 34. One end of the sealing rod 56 is in contact with the inner surface of the insulating rock wool block 34, thus sealing the space between one end of the insulating rock wool sheet 35 and the inner surface of the insulating rock wool block 34.

[0046] In this way, the mobile phone mounted on the upper wall of the supporting component 3 is located inside the two pairs of thermal insulation rock wool sheets 35. The air in the second operating chamber 24 directly reaches the box 31 through the air guide channel 32. Then the air continues to reach the thermal insulation rock wool sheets 35 through the first air supply channel 33, the plastic channel 37 and the second air supply channel 36, thereby driving the thermal insulation rock wool sheets 35 to move inward, so that the two pairs of thermal insulation rock wool sheets 35 clamp the mobile phone here, improving the reliability of the mobile phone. At the same time, the air in the thermal insulation rock wool block 34 is discharged through the hole 38, maintaining the air inlet volume of the thermal insulation rock wool sheet 35 higher than the air outlet volume of the hole 38, which can constantly maintain the clamping performance of the thermal insulation rock wool sheet 35 on the mobile phone. In addition, the thermal insulation rock wool block 34 and the cuboid part 7 are screwed together so they can be separated. At the same time, the plastic channel 37 and the second air supply channel 36 and the first air supply channel 33 can be separated, which is convenient for the relocation and storage of the positioning component 5.

[0047] The fastening component 6 includes a hollow lower block 39, which is fixed to the lower wall of the L-shaped platform 2. A sheet of polypropylene material 40 is fixed to the lower wall of the lower block 39. An annular column 43 is connected between two pairs of lower blocks 39. The annular column 43 is located on the outer surface of the cover 21 and is formed by a pair of annular channels connected by flanges. One end of the lower block 39 is connected to an air supply channel 44 equipped with a gate valve. An air supply channel 41 is connected between the lower block 39 and the passage 42, and a gate valve 5 is installed on the air supply channel 41.

[0048] Thus, the L-shaped platform 2 is placed on the upper wall of the container. At this time, the lower block 39 of the bonding component 6 below the L-shaped platform 2 is located on the upper wall of the container. During cooling, air is supplied through passage two 42. At this time, the air in the lower block 39 reaches passage two 42 through air supply passage three 41. Because the two pairs of lower blocks 39 are connected by the annular column 43, a pressure lower than the external atmosphere is formed in the two pairs of lower blocks 39. Simultaneously, a sheet of polypropylene material 40 is placed between the lower block 39 and the upper wall of the container, so that the lower block 39... 9. The device is firmly attached to the upper wall of the container to improve the stability of the mounting of the platform body 2, thereby improving the stability of the mobile phone mounting. After the device is firmly mounted, the second gate on the air supply channel 3 41 is cut off. When it is about to remove the lower block 39 from the upper wall of the container, the second gate on the air supply channel 44 is opened to allow the outside air to reach the lower block 39 through the air supply channel 44. This facilitates the separation of the lower block 39 from the upper wall of the container. Also, because the annular column 43 can be disassembled, it facilitates the relocation and storage of the attached component 6. The wireless charging components include a wireless sensing circuit board and a coil.

[0049] The present invention has been described above by way of example. Those skilled in the art should understand that the present disclosure is not limited to the embodiments described above, and various changes, modifications and substitutions can be made without departing from the scope of the present invention.
