Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a wireless charging device and a vehicle. Background Technology

[0002] With the development of smart technology, wireless charging devices are gradually being applied to various aspects of life in order to reduce the need for users to store and organize charging cables for their devices.

[0003] Wireless charging devices are typically used to charge devices such as mobile phones, computers, or headphones. Since most mobile phone cameras nowadays are equipped with multiple lens modules, the camera protrudes from the back of the phone.

[0004] Thus, inconsistent phone back panel heights can cause gaps between the phone back panel and the charging surface when placed on a wireless charging device, affecting charging efficiency. Utility Model Content

[0005] The purpose of this application is to provide a wireless charging device and a vehicle, aiming to solve the problem of how to improve the charging efficiency of the wireless charging device.

[0006] In a first aspect, a wireless charging device is provided, comprising a housing and a charging component, wherein a receiving space is formed within the housing, the charging component is used to charge a terminal device, and the charging component is movable relative to the housing between a first position and a second position; when the charging component is in the first position, the charging component is located within the receiving space; when the charging component is in the second position, at least a portion of the charging component is located outside the receiving space for supporting the terminal device.

[0007] The charging component can move relative to the housing. When the terminal device does not need to be charged, the charging component can move to the first position. At this time, the charging component is located in the housing space. The wireless charging device can act as a storage platform for placing the user's personal belongings, thereby increasing the vehicle's storage space.

[0008] When the terminal device needs charging, the charging component moves to a second position, at least a portion of which is located outside the receiving space. In this way, the surface of the charging component can protrude from the surface of the housing, and the height difference between the charging component and the housing can counteract the protrusion in the phone's camera area. This allows the surface of the charging component to make full contact with the phone's back panel, reducing charging loss and improving the charging efficiency of the wireless charging device.

When the charging component is in the first position, the first surface is flush with the opening and the second surface is located inside the accommodating cavity. When the charging component is in the second position, the first surface is located on the side of the opening opposite to the accommodating cavity, for supporting the terminal device.

[0010] Optionally, the charging component includes a first surface and a second surface opposite to each other, the first surface being used to support the terminal device; the charging component includes a support member and a charging coil, the support member having a receiving groove recessed from the second surface toward the first surface, and the charging coil being disposed in the receiving groove.

[0011] Optionally, the support includes an end plate and a surrounding plate, the surrounding plate being connected to the end plate and defining a receiving groove with the end plate, the side surface of the end plate facing away from the surrounding plate forming a first surface, and the charging coil being disposed on the end plate.

[0014] Optionally, the wireless charging device also includes a detection component and a circuit board. The detection component is used to detect whether the terminal device is placed on or attached to the wireless charging device. The circuit board is housed in the receiving space, and the lifting component, the detection component, and the charging coil are all electrically connected to the circuit board. The circuit board is used to receive information detected by the detection component to control the lifting component to drive the charging component to move.

[0015] Optionally, the lifting assembly includes a drive component and a transmission structure. The drive component is connected to the housing, and the transmission structure is connected between the drive component and the charging assembly. The drive component drives the charging assembly to move through the transmission structure.

[0016] Optionally, the transmission structure includes a lead screw and a screw sleeve. The driving component is connected to the lead screw to drive the lead screw to rotate. The screw sleeve is connected to the charging component and is threadedly connected to the lead screw. The rotation of the lead screw can drive the screw sleeve to move along the axial direction of the lead screw.

[0034] This application provides a vehicle that can be a hybrid vehicle, a range-extended electric vehicle, a plug-in hybrid vehicle, a pure electric vehicle, etc. The vehicle can also be an engineering vehicle, a special-purpose vehicle, etc.

[0035] The vehicle may include a body and wheels. The body is used for passengers and for carrying goods, while the wheels are mounted under the body to support the body and allow it to roll on the road surface to move the vehicle.

[0036] Please refer to Figure 1 , Figure 1This is a schematic diagram of the operation of a wireless charging device 100 provided in an embodiment of this application. The vehicle may also include the wireless charging device 100, which may be installed inside the vehicle body to facilitate the charging of the terminal device 200 by the driver and passengers.

[0037] The wireless charging device 100 is usually installed on the storage panel in the cockpit. When the terminal device 200 is placed on the wireless charging device 100, the wireless charging device 100 can charge the terminal device 200. When the terminal device 200 is removed from the wireless charging device 100, the wireless charging device 100 stops discharging and can be used as a regular storage platform to place miscellaneous items.

[0038] It should be noted that the wireless charging device 100 is not limited to vehicles, but can also be used on desks, dining tables, public seats, etc., so that users can conveniently and quickly charge the terminal device 200 in various scenarios such as working, dining, and traveling.

[0039] The terminal device 200 can be a mobile phone, tablet computer, wireless headphones or smartwatch, etc. In this embodiment, the terminal device 200 is specifically described as a mobile phone.

[0040] Currently, mainstream mobile phones on the market typically feature multiple lens groups, such as wide-angle lenses and / or telephoto lenses, to enrich their functionality and practicality. Therefore, the camera area usually protrudes from the back panel of the phone. However, in the related technology of wireless charging devices 100, the charging panel is usually a flat structure. Thus, when a phone is placed on the wireless charging device 100, the phone's back panel cannot fit snugly against the panel of the wireless charging device 100, resulting in a gap between the phone and the wireless charging device 100. This increases the distance between the phone and the charging component 20, affecting charging efficiency.

[0041] Based on this, please refer to Figures 2-5 , Figure 2 for Figure 1 The diagram shown illustrates the structure of the wireless charging device 100 with the charging component 20 in the first position. Figure 3 for Figure 1 The diagram shown illustrates the structure of the wireless charging device 100 with the charging component 20 in the second position. Figure 4 for Figure 1 The cross-sectional view of the wireless charging device shown is shown. Figure 5 for Figure 1 An exploded view of the wireless charging device is shown. This application provides a wireless charging device 100, which includes a housing 10 and a charging component 20. The charging component 20 is used to charge a terminal device 200, and the charging component 20 is movable relative to the housing 10 between a first position and a second position.

[0042] The housing 10 has a receiving space 11. When the charging component 20 is in the first position, the charging component 20 is located inside the receiving space 11. When the charging component 20 is in the second position, at least a portion of the charging component 20 is located outside the receiving space 11 to support the terminal device 200.

[0043] The charging component 20 can move relative to the housing 10. When the terminal device 200 does not need to be charged, the charging component 20 can move to the first position. At this time, the charging component 20 is located in the accommodating space 11. The wireless charging device 100 can act as a storage platform for placing the user's personal belongings, thereby increasing the vehicle's storage space.

[0044] When the terminal device 200 needs charging, the charging component 20 moves to a second position, at which point at least a portion of the charging component 20 is located outside the receiving space 11. Thus, the surface of the charging component 20 can protrude from the surface of the housing 10, and the height difference between the charging component 20 and the housing 10 can counteract the protrusion in the phone's camera area, thereby ensuring sufficient contact between the surface of the charging component 20 and the phone's back panel, reducing charging loss, and improving the charging efficiency of the wireless charging device 100.

[0045] Thus, the charging component 20 is movable relative to the housing 10, which can improve the charging efficiency of the wireless charging device 100 and restore its storage function when charging stops, preventing the storage from being unstable due to uneven surfaces between the charging component 20 and the housing 10.

[0046] In some embodiments, the housing 10 may include a detachably connected upper housing 14 and a lower housing 15, which facilitates the assembly of the wireless charging device 100.

[0047] In some embodiments, the upper housing 14 can be made of insulating materials such as plastic or silicone. In this way, the upper housing 14 can insulate the circuits in the housing space 11 from the outside of the housing 10, thereby reducing the risk of leakage of the wireless charging device 100.

[0048] In some embodiments, the lower housing 15 can be housed inside the interior structure of a vehicle. Therefore, the lower housing 15 can be made of insulating materials such as plastic or silicone, or non-insulating materials such as aluminum alloy or copper. This application does not limit the specific materials used in this application.

[0049] In some embodiments of this application, the accommodating space 11 may include a accommodating cavity 12 and an opening 13 communicating with the accommodating cavity 12, and the charging assembly 20 includes a first surface 201 and a second surface opposite to each other. When the charging assembly 20 is in a first position, the first surface 201 is flush with the opening 13, and the second surface is located inside the accommodating cavity 12; when the charging assembly 20 is in a second position, the first surface 201 is located on the side of the opening 13 opposite to the accommodating cavity 12, for supporting the terminal device 200.

[0050] Since the accommodating space 11 includes an accommodating cavity 12 and an opening 13 communicating with the accommodating cavity 12, when the charging component 20 is in the first position, the charging component 20 can be located in both the accommodating cavity 12 and the opening 13. Specifically, the first surface 201 of the charging component 20 can be flush with the opening 13, and the second surface is located inside the accommodating cavity 12. In this way, the first surface 201 of the charging component 20 can be flush with the surface of the housing 10, thereby making the wireless charging device 100 stable when not in charging mode and improving the aesthetic appearance of the wireless charging device 100.

[0051] When the charging component 20 is in the second position, at least a portion of the charging component 20 is located outside the receiving space 11, that is, at least a portion of the charging component 20 can pass through the opening 13 to the outside of the housing 10. Specifically, the first surface 201 is located on the side of the opening 13 facing away from the receiving cavity 12, and the second surface can be located inside the receiving cavity 12, flush with the opening 13, or located on the side of the opening 13 facing away from the receiving cavity 12. The position of the second surface can be adjusted according to the height requirements of the terminal device 200, and this application does not specifically limit the position of the second surface.

[0052] In this way, the first surface 201 can be disposed outside the accommodating space 11 to support the terminal device 200 (such as a mobile phone), which can lift the mobile phone from the surface of the housing 10, thereby eliminating the gap between the mobile phone back panel and the charging component 20 caused by the unevenness of the mobile phone back panel surface, reducing the distance between the charging component 20 and the mobile phone back panel, and improving charging efficiency.

[0053] In some embodiments, the shape and size of the opening 13 may be consistent with the shape and size of the first surface 201 of the charging component 20. In this way, when the charging component 20 is in the first position, the charging component 20 and the opening 13 can fit together, so that the surface of the wireless charging device 100 is flat, reducing the surface depressions or gaps of the wireless charging device 100, thereby reducing the entry of dust or foreign objects into the device and enhancing the protection of electronic devices in the housing cavity 12.

[0054] In some embodiments, the shape of the opening 13 may be circular, square, polygonal, or irregular, etc., and this application does not further limit it.

[0055] In some embodiments of this application, the charging component 20 includes a first surface 201 and a second surface opposite to each other. The first surface 201 is used to support the terminal device 200. The charging component 20 includes a support member 21 and a charging coil 22. The support member 21 is provided with a receiving groove 211, which is recessed from the second surface toward the first surface 201. The charging coil 22 is disposed in the receiving groove 211.

[0056] The charging coil 22 can generate an alternating magnetic field when connected to electricity. When the terminal device 200 is placed in the alternating magnetic field, the receiving coil inside the terminal device 200 can convert the magnetic field energy into electrical energy, thereby enabling the terminal device 200 to be charged.

[0057] The support member 21 can be used to support the terminal device 200. A receiving groove 211 is provided in the support member 21, and the charging coil 22 is located in the receiving groove 211. The internal space of the support member 21 can be fully utilized, so that the charging coil 22 is close to the first surface 201, thereby shortening the distance between the charging coil 22 and the terminal device 200 and improving the charging efficiency of the wireless charging device 100.

[0058] In addition, by placing the charging coil 22 in the receiving groove 211, the support member 21 can fix and protect the charging coil 22, preventing the charging coil 22 from deforming when subjected to impact or vibration, thus affecting the performance of the wireless charging device 100.

[0059] In some embodiments, the support member 21 may include an end plate 212 and a surrounding plate 213. The surrounding plate 213 is connected to the end plate 212 and defines an accommodating groove 211 with the end plate 212. A first surface 201 is formed on the side surface of the end plate 212 opposite to the surrounding plate 213. The charging coil 22 is disposed on the end plate 212.

[0060] The enclosure 213 is connected to the end plate 212. When the charging assembly 20 is in the second position, the end plate 212 can be located outside the receiving space 11, and the enclosure 213 can be located at the opening 13, thereby enhancing the stability and support strength of the support member 21.

[0061] In addition, when the charging coil 22 is placed in the receiving groove 211 defined by the end plate 212 and the surrounding plate 213, the shape of the surrounding plate 213 or the end plate 212 can be adjusted according to the shape and size of the charging coil 22, so as to accommodate charging coils 22 of different sizes and shapes, making the layout of the wireless charging device 100 more compact.

[0062] In some embodiments of this application, the charging assembly 20 further includes a heat sink 23, at least a portion of which is located within the receiving groove 211, and the charging coil 22 is connected to the heat sink 23.

[0063] Since the charging coil 22 generates heat when powered on, overheating of the charging coil 22 may cause a decrease in the performance of the wireless charging device 100. Therefore, a heat sink 23 is connected to the charging coil 22, so that the heat from the charging coil 22 can be conducted to the heat sink 23, thereby cooling the charging coil 22 and reducing the risk of overheating.

[0064] In some embodiments, the heat sink 23 may be arranged around the charging coil 22, so that the heat of the charging coil 22 can be conducted to the heat sink 23, thereby dissipating heat from the charging coil 22.

[0065] In other embodiments, the heat sink 23 can be a planar structure, and the side surface of the charging coil 22 facing away from the first surface 201 is connected to the heat sink 23. In this way, the contact area between the heat sink 23 and the charging coil 22 can be increased, thereby further improving the heat dissipation performance of the heat sink 23.

[0066] In some other embodiments, the surface of the heat sink 23 facing the charging coil 22 may be provided with a mounting groove, and at least a portion of the charging coil 22 may be disposed within the mounting groove. This makes the connection between the charging coil 22 and the heat sink 23 more stable and prevents displacement between them. Furthermore, by disposing the charging coil 22 within the mounting groove, both one side surface and the circumference of the charging coil 22 can exchange heat with the heat sink 23, thereby further improving heat dissipation efficiency.

[0067] In some embodiments, the heat sink 23 can be made of a metal material. Since metal has good thermal conductivity, it can further improve heat dissipation efficiency. For example, the heat sink 23 can be aluminum alloy or copper, etc.

[0068] In some embodiments, the heat sink 23 can be bonded to the charging coil 22, which makes the connection between the heat sink 23 and the charging coil 22 more stable and prevents displacement due to vibration or impact.

[0069] In some embodiments, the wireless charging device 100 further includes a lifting component 30, which is disposed within the receiving space 11 and is connected to the charging component 20 via a transmission connection, for driving the charging component 20 to move between a first position and a second position.

[0070] In this way, when the wireless charging device 100 needs to charge the terminal device 200, the lifting component 30 can drive the charging component 20 to rise from the receiving space 11 and move the charging component 20 to the second position, which is in contact with the back panel of the terminal device 200, thereby improving charging efficiency; when the wireless charging device 100 does not need to charge the terminal device 200, the lifting component 30 can drive the charging component 20 to fall down until the first surface 201 is flush with the opening 13, thereby restoring the surface of the wireless charging device 100 to its storage function.

[0071] By using the lifting component 30 to control the movement of the charging component 20, the lifting operation of the charging component 20 can be made simpler, making it easier for the wireless charging device 100 to charge the terminal device 200.

[0072] In the embodiments of this application, the lifting component 30 can be a manual lifting structure to control the raising and lowering of the charging component 20, or it can be an automatic lifting device.

[0073] When the lifting assembly 30 is a manual lifting structure, the lifting assembly 30 can be a lever structure, a spring buckle structure, etc., and this application does not limit it.

[0074] For example, in some embodiments, when the lifting component 30 is a lever structure, the lever structure includes a lever and a limiting structure. The side of the housing 10 is provided with an opening 13. One end of the lever is connected to the charging component 20, and the other end of the lever extends out of the housing 10 through the opening 13. The limiting structure can limit the lever when it reaches the second position.

[0075] When the wireless charging device 100 needs to charge the terminal device 200, the lever can be manually moved to raise the charging component 20 from the receiving space 11 and move it to a second position, where it fits against the back panel of the terminal device 200. When the wireless charging device 100 does not need to charge the terminal device 200, moving the lever can lower the charging component 20 until the first surface 201 is flush with the opening 13, thereby restoring the surface of the wireless charging device 100 to its storage function.

[0076] For example, in some other embodiments, the lifting assembly 30 is a spring-loaded latch structure, which may include a limiting member, a pressing member connected to the charging assembly 20, and a spring connected between the pressing member and the housing 10.

[0077] When the charging component 20 is in the second position, the limiting member does not limit the pressing member. Under the support of the spring force, the pressing member pushes the charging component 20 out of the receiving space of the housing 10. When the charging component 20 needs to move to the first position, the charging component 20 can be pressed, causing the pressing member to compress the spring. When the charging component 20 moves to the first position, the limiting member limits the pressing member, so that the charging component 20 is stable in the first position.

[0078] When the charging component 20 needs to move from the first position to the second position, press the charging component 20 again so that the limiting member no longer limits the pressing member. Under the elastic force of the spring, the pressing member moves the charging component 20 to the second position. Specifically, the structure and cooperation of the limiting member, the pressing member, and the spring can be referred to as the pressing and lifting structure of a ballpoint pen.

[0079] When the lifting assembly 30 is an automatic lifting structure, the lifting assembly 30 can be a screw and nut structure, a cam and connecting rod structure, a gear and rack structure, an electromagnetic lifting structure, or a hydraulic lifting structure, etc., and this application does not limit it.

[0080] For example, in some embodiments, the lifting assembly 30 may include a driving member 31 and a transmission structure 32. The driving member 31 is connected to the housing 10, and the transmission structure 32 is connected between the driving member 31 and the charging assembly 20. The driving member 31 drives the charging assembly 20 to move through the transmission structure 32.

[0081] The drive component 31 is connected to the housing 10, which can reduce displacement and shaking caused by vehicle vibration, thereby improving the stability and reliability of the lifting assembly 30.

[0082] The transmission structure 32 is connected between the drive component 31 and the charging component 20. It can transmit the power of the drive component 31 to the charging component 20, thereby driving the charging component 20 to move between the first position and the second position, realizing the lifting and lowering of the charging component 20.

[0083] By setting up the drive component 31 and the transmission structure 32, the charging component 20 can be automatically raised and lowered, making operation simpler and improving the user experience.

[0084] The drive component 31 can be a motor, cylinder, or hydraulic assembly, etc., and can be specifically configured according to the requirements of the transmission structure 32.

[0085] In some embodiments, the transmission structure 32 may include a lead screw 321 and a threaded sleeve 322. The driving member 31 is connected to the lead screw 321 to drive the lead screw 321 to rotate. The threaded sleeve 322 is connected to the charging assembly 20 and is threadedly connected to the lead screw 321. The rotation of the lead screw 321 can drive the threaded sleeve 322 to move along the axial direction of the lead screw 321.

[0086] In this way, the drive unit 31 can drive the lead screw 321 to rotate, and the screw sleeve 322 can be sleeved on the lead screw 321. When the lead screw 321 rotates, the screw sleeve 322 can move along the axial direction of the lead screw 321 under the guidance of the thread. The screw sleeve 322 can be connected to the charging component 20, thereby pushing the charging component 20 to move linearly along the extension direction of the lead screw 321.

[0087] Because the lead screw and sleeve drive has a self-locking function, when the drive component 31 stops working, the sleeve 322 can remain fixed in that position to prevent the charging component 20 from sliding down due to gravity, thereby improving the reliability of the lifting component 30.

[0088] To prevent the charging component 20 from rotating along with the screw 321 along with the threaded sleeve 322, in some embodiments, the outer peripheral wall of the support member 21's enclosure 213 may be provided with either a limiting groove or a limiting protrusion, and the inner peripheral wall of the opening 13 of the housing 10 may be provided with either a limiting groove or a limiting protrusion. The limiting groove and the limiting protrusion cooperate with each other, and the limiting protrusion can move relative to the limiting groove along the axial direction of the screw 321. In this way, the rotation of the charging component 20 can be restricted, so that only linear lifting motion is performed, thereby improving the transmission efficiency of the transmission structure 32.

[0089] For example, in some other embodiments, the transmission structure 32 may further include a first link and a second link arranged in a cross configuration, with the center positions of the first link and the second link connected, and the first link and the second link being rotatable relative to each other. Along the moving direction of the charging assembly 20, the first link includes a first end and a second end, and the second link includes a third end and a fourth end. The first end is rotatably connected to the housing 10, the third end is slidably connected to the housing 10, the second end is rotatably connected to the charging assembly 20, and the fourth end is slidably connected to the charging assembly 20. That is, the first link and the second link form an X-shaped scissor-type lifting structure.

[0090] Along a direction perpendicular to the movement of the charging assembly 20, the drive member is connected to one of the third and fourth ends, and the drive member can drive the third and fourth ends to slide along the direction perpendicular to the movement of the charging assembly 20. In this way, the distance between the ends of the first and second links along the direction perpendicular to the movement of the charging assembly 20 can be increased or decreased, thereby adjusting the lifting and lowering of the charging assembly 20.

[0091] In some embodiments, the transmission structure 32 may further include a bracket 323, which is located between the threaded sleeve 322 and the charging component 20, and is fixedly connected to both the bracket 323, the threaded sleeve 322, and the charging component 20. The bracket 323 may include a supporting plane for supporting the charging component 20. This increases the contact area between the transmission structure 32 and the charging component 20, making the connection between the charging component 20 and the transmission structure 32 more stable.

[0092] The transmission structure 32 can be made of steel. Since steel has high strength, the transmission structure 32 can be more stable, thereby improving the reliability of the wireless charging device 100.

[0093] In some embodiments, the rising height of the charging component 20 can be a fixed value. For example, the rising height of the charging component 20 can be 2 to 5 mm, such as 2 mm, 4 mm, or 5 mm. In other embodiments, the rising height of the charging component 20 can be movable. Specifically, the rising height of the charger can be controlled by controlling the operation and stopping of the control drive 31 according to the user's needs.

[0094] When the height of the charging component 20 is equal to the height of the phone camera area protruding from the back panel of the phone, the first surface 201 of the charging component 20 can fit against the back panel of the phone to support the phone. At the same time, the outer surface of the housing 10 can fit against the camera area of ​​the phone to support the phone as well. In this way, the phone can be more stable and the risk of the phone falling can be reduced.

[0095] In some embodiments, the wireless charging device 100 further includes a detection component and a circuit board 40. The detection component is used to detect whether the terminal device 200 is placed on or attached to the wireless charging device 100. The circuit board 40 is housed in the receiving space 11, and the lifting component 30, the detection component, and the charging coil 22 are all electrically connected to the circuit board 40. The circuit board 40 is used to receive information detected by the detection component in order to control the lifting component 30 to drive the charging component 20 to move.

[0096] The detection component can be mounted on the housing 10 or the support 21. When the detection component detects a signal (named the first signal) indicating that the terminal device 200 has been placed on the wireless charging device 100, it sends the first signal to the circuit board 40. Upon receiving the first signal, the circuit board 40 controls the lifting component 30 to lift the charging component 20. During the lifting process of the charging component 20, the terminal device 200 is placed on the charging component 20 and rises along with it. When the detection component detects a signal (named the second signal) indicating that the terminal device 200 is in contact with the charging component 20, it sends the second signal to the circuit board 40. Upon receiving the second signal, the circuit board 40 controls the lifting component 30 to stop moving. When the detection component detects a signal (named the third signal) indicating that the terminal device 200 has left the wireless charging device 100, it sends the third signal to the circuit board 40. Upon receiving the third signal, the circuit board 40 controls the lifting component 30 to lower the charging component 20 to a first position, where the first surface 201 of the charging component 20 is flush with the opening 13 and the second surface is located within the receiving cavity 12.

[0097] In this way, users can raise and lower the charging component 20 without manually adjusting the lifting component 30 or manually controlling the start and stop of the drive component 31. The charging operation of the wireless charging device 100 is more convenient and the user experience is better.

[0098] For example, a controller may be provided on the circuit board 40, which can receive signals sent by the detection component and control the lifting component 30 to drive the charging component 20 to rise or fall.

[0099] In some embodiments of this application, the drive element 31 can be disposed on the side of the circuit board 40 away from the charging component 20. In this way, the space along the axial direction of the lead screw 321 of the transmission structure 32 can be fully utilized, making the layout more compact and saving the space requirement of the wireless charging device 100.

[0100] In addition, by placing the driver 31 on the side of the circuit board 40 away from the charging component 20, the gravitational pressure of the driver 31 on the circuit board 40 and the damage to the circuit structure caused by the vibration of the driver 31 can be avoided, thereby improving the stability and reliability of the wireless charging device 100.

[0101] In some embodiments, the wireless charging device 100 may further include a cooling fan 50 disposed within the receiving space 11. Thus, the cooling fan 50 can dissipate heat from the wireless charging device 100, preventing the device from overheating during charging and affecting its performance and lifespan.

[0102] In some embodiments, the wireless charging device 100 may further include a shielding panel 60, which is disposed on the side of the circuit board 40 facing the charging assembly 20 and is fixedly connected to the housing 10. The shielding panel 60 can protect the circuit board 40, reduce interference from external electromagnetic signals to the signals of the circuit board 40, and improve the reliability of the wireless charging device 100.

[0103] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0104] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
