Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative positional relationship, movement condition and the like between components in a certain specific posture, and if the specific posture changes, the directional indications will also change accordingly. In the present application, unless otherwise specifically defined and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For ordinary skilled persons in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features.

[0041] Wireless charging is one of the future development directions of new energy vehicle charging, which can realize automatic charging without the operation of plugging and unplugging the gun, and the charging process is more convenient.

[0042] The alignment of the ground transmitting end and the vehicle receiving end not only affects the efficiency and power of wireless charging, but also affects the success probability and reliability of wireless charging.

[0043] At present, most of the wireless charging systems on the market are for the vehicle end to move to match the ground transmitting end. This mode can rely on the driver to adjust the vehicle position, so that the vehicle receiving end is aligned with the ground transmitting end, but the technical requirements for the driver are relatively high, and the driver is difficult to park in place, which brings bad user experience to the driver. With the progress of technology, this mode can also rely on the automatic parking technology of the vehicle, but the automatic parking technology is currently limited by the parking environment, and the parking environment has a great influence on the automatic driving parking accuracy. If the parking is not in place, wireless charging may not be performed.

[0044] Therefore, in the related art, when wireless charging is performed on a vehicle, there is a technical problem that the technical requirements for the driver are relatively high. The embodiments of the present application provide a wireless charging device and a wireless charging system, which can at least solve the technical problem that the technical requirements for the driver are relatively high when wireless charging is performed on a vehicle

[0045] The application will be described below with reference to the accompanying drawings and specific embodiments:

[0046] As shown in Figure 1 and Figure 2 Wireless charging device 200 is used to charge a device to be charged 2000, which includes a receiving module 2100. Wireless charging device 200 includes a transmitting module 210 and a driving assembly 220. The transmitting module 210 is installed at the output end of the driving assembly 220, and the driving assembly 220 drives the transmitting module 210 to move along the X direction, Y direction and Z direction respectively, so that the transmitting module 210 is aligned with the receiving module 2100 of the device to be charged 2000. The X direction, Y direction and Z direction are perpendicular to each other.

[0047] The device to be charged 2000 can be an electric vehicle, a two-wheeled electric vehicle, a three-wheeled electric vehicle, etc., which is not limited in the application. The driving assembly 220 can drive the transmitting module 210 to move along the X direction, or drive the transmitting module 210 to move along the Y direction, or drive the transmitting module 210 to move along the Z direction. After such design, the position of the transmitting module 210 can be adjusted in three-dimensional space, so that the transmitting module 210 can be actively aligned with the receiving module 2100 under the driving of the driving assembly 220, reducing the technical requirements for the driver when the vehicle is wirelessly charged, and providing better user experience for the driver.

[0048] In some embodiments, the wireless charging device 200 further includes a controller 240, and the driving assembly 220 and the device to be charged 2000 are electrically connected to the controller 240; the controller 240 adjusts the action of the driving assembly 220 based on the relative position difference signal sent by the device to be charged 2000, so that the driving assembly 220 drives the transmitting module 210 to align with the receiving module 2100 of the device to be charged 2000.

[0049] The device to be charged 2000 can detect the relative position difference between the receiving module 2100 and the transmitting module 210, and send the relative position difference to the controller 240. After receiving the relative position difference sent by the device to be charged 2000, the controller 240 controls the action of the driving assembly 220 based on the relative position difference, adjusts the position of the transmitting module 210 in the X direction, Y direction and Z direction, so that the transmitting module 210 and the receiving module 2100 are aligned in the X direction and Y direction, and the height difference between the transmitting module 210 and the receiving module 2100 in the Z direction meets the requirements of wireless charging. After such design, the wireless charging device 200 can not be provided with a detection device for detecting the relative position difference between the wireless charging device 200 and the receiving module 2100, which helps to reduce the cost of the wireless charging device 200.

[0050] The relative position difference can be sent to the ground receiving end by the to-be-charged device 2000 through remote communication means, such as WiFi. The implementation manners are various and known to those skilled in the art, and are not limited in the present application.

[0051] In some embodiments, the wireless charging device 200 further comprises a positioning member 230 arranged on the transmitting module 210, which is used to be detected by the to-be-charged device 2000.

[0052] The to-be-charged device 2000 can detect the position of the positioning member 230 and calculate the relative position difference between the receiving module 2100 and the transmitting module 210 according to the position of the positioning member 230. The number of the positioning member 230 can be one or more. The structure of the positioning member 230 is various, which can be in the shape of a cross or a sphere, and is not limited in the present application. It should be noted that the positioning member 230 should be arranged at a place that can be detected by the detector of the to-be-charged device 2000. In some embodiments, the positioning member 230 is arranged on the upper end face of the transmitting module 210.

[0053] In some embodiments, a plurality of positioning members 230 are arranged, which are arranged in a row.

[0054] The arrangement of a plurality of positioning members 230 on the transmitting module 210 can provide more reference points for the to-be-charged device 2000, so that the to-be-charged device 2000 can more accurately calculate the relative position difference between the receiving module 2100 and the transmitting module 210, thereby improving the alignment accuracy of the receiving module 2100 and the transmitting module 210. In addition, through the arrangement of a plurality of positioning members 230, if one of the positioning members 230 cannot be detected due to pollution, shielding or other reasons, the other positioning members 230 can still provide effective positioning information, thereby improving the reliability of the wireless charging device 200. The plurality of positioning members 230 are arranged in a row, so that these positioning members 230 are not located on the same straight line, which is helpful for the to-be-charged device 2000 to more accurately calculate the relative position difference between the receiving module 2100 and the transmitting module 210.

[0055] In some embodiments, four positioning members 230 are arranged, which are arranged at the four corners of the transmitting module 210, and the positioning member 230 is a indicator light.

[0056] In the embodiments, the transmitting module 210 is cuboid-shaped, and the four positioning members 230 are respectively located at the four corners of the transmitting module 210. The indicator light can emit light, so that after the design, the detector of the device to be charged 2000 can clearly detect the position of the transmitting module 210 in the night or in a relatively dark environment, thereby improving the accuracy and reliability of the positioning. In addition, when the driving assembly 220 of the wireless charging device 200 is damaged, the light emitted by the indicator light can also provide intuitive visual guidance for the driver, helping the driver to quickly judge the relative position of the vehicle and the transmitting module 210, simplifying the alignment operation, and improving the convenience of wireless charging and user experience.

[0057] In some embodiments, the device to be charged 2000 obtains the approximate position of the transmitting module 210 by the camera arranged on the bottom, and calculates the relative position difference between the center of the receiving module 2100 and the center of the transmitting module 210 in the X direction, the Y direction and the Z direction according to the four indicator lights.

[0058] In some embodiments, the driving assembly 220 includes a Z-direction driving mechanism 221, an X-direction driving mechanism 222 and a Y-direction driving mechanism 223. The X-direction driving mechanism 222 is installed on the output end of the Z-direction driving mechanism 221, and the Z-direction driving mechanism 221 drives the X-direction driving mechanism 222 to move along the Z direction; the Y-direction driving mechanism 223 is installed on the output end of the X-direction driving mechanism 222, and the X-direction driving mechanism 222 drives the Y-direction driving mechanism 223 to move along the X direction, and the transmitting module 210 is installed on the output end of the Y-direction driving mechanism 223, and the Y-direction driving mechanism 223 drives the transmitting module 210 to move along the Y direction.

[0059] The X-direction driving mechanism 222 is installed on the output end of the Z-direction driving mechanism 221, so that the Z-direction driving mechanism 221 can drive the X-direction driving mechanism 222 to move in the Z direction. The Y-direction driving mechanism 223 is installed on the output end of the X-direction driving mechanism 222, so that the Z-direction driving mechanism 221 can drive the Y-direction driving mechanism 223 to move in the Z direction. The transmitting module 210 is installed on the output end of the Y-direction driving mechanism 223, so that the Z-direction driving mechanism 221 can drive the transmitting module 210 to move in the Z direction, thereby adjusting the position of the transmitting module 210 in the Z direction.

[0060] The Y-direction driving mechanism 223 is installed on the output end of the X-direction driving mechanism 222, and the transmitting module 210 is installed on the output end of the Y-direction driving mechanism 223, so that the X-direction driving mechanism 222 can drive the transmitting module 210 to move in the X direction, thereby adjusting the position of the transmitting module 210 in the X direction.

[0061] The Y-direction driving mechanism 223 drives the transmitting module 210 to move along the Y direction, thereby adjusting the position of the transmitting module 210 in the Y direction.

[0062] In this way, the position of the launching module 210 in the X direction can be adjusted by controlling the X direction driving mechanism 222 to act, the position of the launching module 210 in the Y direction can be adjusted by controlling the Y direction driving mechanism 223 to act, and the position of the launching module 210 in the Z direction can be adjusted by controlling the Z direction driving mechanism 221 to act. In this way, the launching module 210 can move in only one direction or in multiple directions at the same time, the adjustment efficiency of the position of the launching module 210 is higher, the time for aligning the launching module 210 and the receiving module 2100 can be shortened, and the efficiency of wireless charging can be improved.

[0063] In some embodiments, the Z direction driving mechanism 221 comprises a base 2211, a tray 2212, a first support 2213, a second support 2214, and a Z direction driving member 2215. The base 2211 and the tray 2212 are arranged in the Z direction with a spacing, and the X direction driving mechanism 222 is installed on the tray 2212. The first support 2213 and the second support 2214 are rotationally connected at the middle part thereof. The first support 2213 has a first end and a second end arranged oppositely, the first end is rotationally connected with the base 2211, and the second end is slidingly connected with the tray 2212. The second support 2214 has a third end and a fourth end arranged oppositely, the third end is slidingly connected with the base 2211, and the fourth end is rotationally connected with the tray 2212. The Z direction driving member 2215 is installed on the base 2211 and is used to drive the third end to move towards the first end or to move away from the first end.

[0064] The Z direction driving member 2215 is electrically connected with a controller 240, and the controller 240 controls the Z direction driving member 2215 to act. The first support 2213 and the second support 2214 are rotationally connected at the middle part thereof, forming an “X” shape structure. As shown in FIG. 2, the Z direction driving member 2215 is arranged between the first support 2213 and the second support 2214. Figure 1As shown, the lower end of the first support 2213 is the first end, and the upper end is the second end. The upper end of the second support 2214 is the fourth end, and the lower end is the third end. When the Z-direction driving member 2215 drives the third end to move towards the first end, the distance between the third end and the first end gradually decreases, the angle between the first support 2213 and the second support 2214 decreases, the tray 2212 gradually rises along the Z-direction, so that the emission module 210 gradually rises along the Z-direction. When the Z-direction driving member 2215 drives the third end to move away from the first end, the distance between the third end and the first end gradually increases, the angle between the first support 2213 and the second support 2214 increases, the tray 2212 gradually lowers along the Z-direction, so that the emission module 210 gradually lowers along the Z-direction. The middle part of the first support 2213 and the second support 2214 are rotationally connected to form an "X" shape structure, so that the force acting on the tray 2212 can be evenly distributed to the two supports 129, avoiding the tray 2212 from tilting or shaking during the lifting process, and ensuring the stability of the emission module 210 during lifting. In addition, this design allows the first support 2213 and the second support 2214 to be folded towards each other when the wireless charging device 200 is not in use, reducing the space occupied by the Z-direction driving mechanism 221 in the Z-direction.

[0065] In some embodiments, the first support 2213 and the second support 2214 are both arranged between the base 2211 and the tray 2212.

[0066] In some embodiments, the Z-direction driving member 2215 is an electric push rod, and the piston rod of the electric push rod is rotationally connected to the third end.

[0067] In some embodiments, the first end and the third end are arranged along the X-direction, and the piston rod of the electric push rod is also arranged along the X-direction.

[0068] In some embodiments, the X-direction driving mechanism 222 includes an X-direction driving member 2221 and an X-direction support table 2222. The X-direction driving member 2221 is installed on the output end of the Z-direction driving mechanism 221; the X-direction support table 2222 is installed on the output end of the X-direction driving member 2221, the X-direction driving member 2221 drives the X-direction support table 2222 to move along the X-direction, and the Y-direction driving mechanism 223 is installed on the X-direction support table 2222.

[0069] The output end of the Z-direction driving mechanism 221 is a tray 2212, and the X-direction driving member 2221 is installed on the tray 2212. The X-direction driving member 2221 is electrically connected with the controller 240, and the controller 240 controls the action of the X-direction driving member 2221. The X-direction support table 2222 is installed on the output end of the X-direction driving member 2221, and the output end of the X-direction driving member 2221 drives the X-direction support table 2222 to move along the X-direction. The Y-direction driving mechanism 223 is installed on the X-direction support table 2222, and the emission module 210 is installed on the output end of the Y-direction driving mechanism 223, so that the emission module 210 can be driven to move along the X-direction.

[0070] In some embodiments, the X-direction support table 2222 is slidingly connected with the tray 2212 along the X-direction, so as to improve the stability of the movement of the X-direction support table 2222 along the X-direction.

[0071] In some embodiments, the X-direction driving member 2221 is an electric push rod, the piston rod of the electric push rod is fixedly connected with the X-direction support table 2222, and the piston rod of the electric push rod is arranged along the X-direction.

[0072] In some embodiments, the Y-direction driving mechanism 223 includes a Y-direction driving member 2231 and a Y-direction support table 2232. The Y-direction driving member 2231 is installed on the X-direction support table 2222, and the Y-direction support table 2232 is installed on the output end of the Y-direction driving member 2231. The Y-direction driving member 2231 drives the Y-direction support table 2232 to move along the Y-direction, and the emission module 210 is installed on the Y-direction support table 2232.

[0073] The Y-direction driving member 2231 is electrically connected with the controller 240, and the controller 240 controls the action of the Y-direction driving member 2231. The Y-direction driving member 2231 is installed on the X-direction support table 2222, and the Y-direction support table 2232 is installed on the Y-direction driving member 2231. Therefore, the X-direction support table 2222 can drive the Y-direction driving member 2231 to move along the X-direction, so as to drive the Y-direction support table 2232 to move along the X-direction, and drive the emission module 210 on the Y-direction support table 2232 to move along the X-direction. The Y-direction driving member 2231 drives the Y-direction support table 2232 to move along the Y-direction, so as to drive the emission module 210 on the Y-direction support table 2232 to move along the Y-direction.

[0074] In some embodiments, the Y-direction support table 2232 is slidingly connected with the X-direction support table 2222 along the Y-direction, so as to improve the stability of the movement of the Y-direction support table 2232 along the Y-direction.

[0075] In some embodiments, the Y-direction driving member 2231 is an electric push rod, the piston rod of the electric push rod is fixedly connected with the Y-direction support table 2232, and the piston rod of the electric push rod is arranged along the Y-direction.

[0076] In some embodiments, the controller 240 is installed below the tray 2212. By installing the controller 240 below the tray 2212, the space below the tray 2212 can be effectively utilized, and the space above or around the tray 2212 can be avoided, so that the overall structure of the wireless charging device 200 is more compact. The position below the tray 2212 can provide certain physical protection for the controller 240, avoid damage to the controller 240 by external collision or rainwater, and help to prolong the service life of the controller 240.

[0077] As shown in Figure 3 Based on the same inventive concept, the embodiments of the present application also provide a wireless charging system 1000, which comprises a shielding device 100 and the above-mentioned wireless charging device 200. The shielding device 100 is used to shield the wireless charging device 200. The shielding device 100 comprises a shielding member 110 and a shielding driving mechanism 120. The shielding member 110 is installed on the shielding driving mechanism 120. The shielding driving mechanism 120 drives the shielding member 110 to move, so that the shielding member 110 can be switched between a shielding position above the wireless charging device 200 and a stowed position outside the wireless charging device 200.

[0078] The shielding member 110 of the shielding device 100 is used to shield the wireless charging device 200. The shielding driving mechanism 120 is used to drive the shielding member 110 to move, so that the shielding member 110 can be located above the wireless charging device 200, thereby shielding the wireless charging device 200, and avoiding the accumulation of foreign matter such as fallen leaves and dust on the wireless charging device 200. The shielding member 110 can also be located outside the wireless charging device 200, that is, the shielding member 110 is moved to not be located above the wireless charging device 200, thereby avoiding the interference of the shielding member 110 and the foreign matter such as fallen leaves and dust thereon with the wireless charging device 200, and ensuring the charging efficiency and safety of the wireless charging device 200.

[0079] In this way, when the wireless charging device 200 is not working, the shielding driving mechanism 120 can be controlled to move, so that the shielding member 110 is located above the wireless charging device 200, shielding the wireless charging device 200, and avoiding the foreign matter such as fallen leaves and dust from falling on the wireless charging device 200 and polluting the wireless charging device 200. When the wireless charging device 200 is charging the to-be-charged device 2000, the shielding driving mechanism 120 drives the shielding member 110 to move, so that the shielding member 110 is located outside the wireless charging device 200, thereby avoiding the interference of the shielding member 110 and the foreign matter such as fallen leaves and dust thereon with the wireless charging, and ensuring the wireless charging efficiency and safety.

[0080] As shown in Figures 4 to 7As shown, in some embodiments, the shielding driving mechanism 120 drives the shielding piece 110 to be rolled up so that the shielding piece 110 is located in the storage position, and the shielding driving mechanism 120 also drives the shielding piece 110 to be unfolded so that the shielding piece 110 is located in the shielding position.

[0081] The shielding piece 110 is in the form of a sheet. When the shielding piece 110 is to be in the storage position, the shielding driving mechanism 120 drives the shielding piece 110 to be rolled up in a column shape. When the shielding piece 110 is to be in the shielding position, the shielding driving mechanism 120 drives the shielding piece 110 to be unfolded from the column shape to the sheet shape and cover the wireless charging device 200. In this way, when the shielding piece 110 is rolled up, foreign matters on the surface of the shielding piece 110 can fall off under the action of gravity, reducing the need for manual cleaning, thereby reducing the maintenance cost of the shielding device 100 and the labor intensity of personnel. At the same time, the shielding piece 110 has a reduced volume after being rolled up, and the occupied space is also reduced, so that the wireless charging device 200 can be installed and arranged in a relatively narrow space.

[0082] The structure of the shielding driving mechanism 120 for driving the shielding piece 110 to be rolled up is various. In some embodiments, the shielding driving mechanism 120 is an electric motor, one side of the shielding piece 110 is fixed to the output shaft of the electric motor, the electric motor rotates clockwise to drive the shielding piece 110 to be rolled up, and the electric motor rotates counterclockwise to drive the shielding piece 110 to be unfolded.

[0083] In some embodiments, the shielding driving mechanism 120 includes a support seat 121, a winding shaft 122, and a driving member 123. The winding shaft 122 is fixedly connected to one side of the shielding piece 110 and rotationally connected to the support seat 121. The driving member 123 is installed on the support seat 121 and transmissionally connected to the winding shaft 122 to drive the winding shaft 122 to rotate.

[0084] In this way, the driving member 123 can drive the winding shaft 122 to rotate, so as to realize the rolling up and unfolding of the shielding piece 110. When the driving member 123 drives the winding shaft 122 to rotate forward, the shielding piece 110 is wound on the winding shaft 122, so as to be rolled up to the storage position. When the driving member 123 drives the winding shaft 122 to rotate reversely, the shielding piece 110 is unfolded from the winding shaft 122, and returns to the shielding position in the form of a sheet. The forward direction can be clockwise or counterclockwise. If the forward direction is clockwise, the reverse direction is counterclockwise. If the forward direction is counterclockwise, the reverse direction is clockwise.

[0085] In some embodiments, the driving member 123 is an electric motor, and the winding shaft 122 is in the form of a cylinder. The winding shaft 122 is fixedly connected to the output shaft of the electric motor and coaxially arranged with the output shaft of the electric motor.

[0086] In some embodiments, the shielding driving mechanism 120 further comprises a guide rail 124 and a guide strip 125; the guide rail 124 is mounted on the support base 121; the guide strip 125 is connected to the other side of the shielding piece 110 and is in sliding connection with the guide rail 124.

[0087] One side of the shielding piece 110 is fixedly connected to the reel 122, and the other side is fixedly connected to the guide strip 125. The guide strip 125 and the guide rail 124 are in sliding connection, which improves the movement precision of the shielding piece 110 and helps to avoid the shielding piece 110 from deviating or twisting. At the same time, the guide strip 125 and the guide rail 124 are in sliding connection, and the shielding piece 110 is fixed to the guide strip 125, which helps to move the shielding piece 110 away from the wireless charging device 200, reduces the wear speed of the shielding piece 110, and helps to prolong the service life of the shielding piece 110. In addition, the structure of the guide rail 124 and the guide strip 125 helps to improve the carrying capacity of the shielding piece 110, so that it can cope with greater load and external force, and enhances the flexibility and reliability of the shielding device 100 in different application scenarios.

[0088] In some embodiments, the shielding piece 110 is formed by sequentially hinging a plurality of shielding plates 111.

[0089] In some embodiments, the shielding driving mechanism 120 further comprises a first gear 126, a second gear 127 and a transmission chain 128. The first gear 126 is rotatably connected to the support base 121; the second gear 127 is in transmission connection with the driving piece 123; the transmission chain 128 is sleeved on the first gear 126 and the second gear 127 and is in meshing connection with the first gear 126 and the second gear 127; the guide strip 125 is connected to the transmission chain 128.

[0090] The second gear 127 can be rotatably mounted on the support base 121 or not. The driving piece 123 can drive the second gear 127 to rotate in a manner that the driving piece 123 is directly connected to the second gear 127 through a rotating shaft, or in a manner that the driving piece 123 indirectly drives the second gear 127 to rotate by setting other transmission components such as gears, which is not limited in the present application. The rotating shafts of the first gear 126 and the second gear 127 are parallel, and the first gear 126 and the second gear 127 are arranged in parallel. The guide strip 125 is fixedly connected to the transmission chain 128.

[0091] Since the transmission chain 128 is engaged with the first gear 126 and the second gear 127 at the same time, and the second gear 127 is in transmission connection with the driving member 123, when the driving member 123 drives the reel 122 to rotate, the second gear 127 rotates accordingly, thereby driving the transmission chain 128 to move. The movement of the transmission chain 128 drives the guide strip 125 to slide along the guide rail 124, thereby realizing the synchronous unfolding or rolling up of the shielding member 110. In this way, during the unfolding of the shielding member 110, the driving member 123 not only drives the reel 122 to rotate to lower the shielding member 110, but also drives the guide strip 125 to move, so that the guide strip 125 pulls the shielding member 110 to move towards the side away from the moving reel 122, which can avoid the occurrence of wrinkles in the shielding member 110. During the rolling up of the shielding member 110, the driving member 123 not only drives the reel 122 to rotate to gradually roll the shielding member 110 into a column shape, but also drives the guide strip 125 to pull the shielding member 110 to move towards the side close to the reel 122, which can ensure the stability of the movement of the guide strip 125.

[0092] In some embodiments, the second gear 127 is coaxially arranged with the output shaft of the driving member 123 and fixedly connected thereto.

[0093] In some embodiments, the first gear 126 and the second gear 127 are arranged in a length direction of the shielding member 110.

[0094] In some embodiments, the guide rail 124 and the transmission chain 128 are arranged in a spaced manner, the shielding member 110 and the guide strip 125 are arranged between the transmission chain 128 and the guide rail 124, and one end of the guide strip 125 close to the guide rail 124 is in sliding connection with the guide rail 124, and the other end close to the transmission chain 128 is fixedly connected with the transmission chain 128.

[0095] The guide rail 124 and the transmission chain 128 are arranged on two sides of the guide strip 125, the guide strip 125 is connected with the guide rail 124 and the transmission chain 128 respectively, and the guide rail 124 and the transmission chain 128 support two ends of the guide strip 125 respectively, so that the stability of the guide strip 125 is better, and the guide strip 125 can provide more stable support for the shielding member 110 when pulling the shielding member 110 to unfold, which helps to make the unfolding and rolling up process of the shielding member 110 more stable and smooth. Moreover, in the environment of strong wind and the like, this structural design can effectively resist the influence of wind on the shielding member 110.

[0096] In some embodiments, the shielding device 100 further comprises a support 129, which is arranged between the guide rail 124 and the reel 122, and the support 129 is rotatably connected to the support seat 121. The shielding member 110 is located on the support 129, and the reel 122 is lower than the support 129.

[0097] The support 129 is rotationally connected to the support base 121, and is located below the shielding member 110 and can support the shielding member 110 on the side close to the reel 122. In this way, one side of the shielding member 110 is supported by the guide strip 125, and the other side of the shielding member 110 is supported by the reel 122, which helps to avoid the shielding member 110 from contacting the wireless charging device 200 during the rolling or unfolding process, and avoids the shielding member 110 from being scratched by the wireless charging device 200. The support 129 is rotationally connected to the support base 121, and when the shielding member 110 is unfolded or rolled up, the shielding member 110 can drive the support 129 to rotate, which helps to reduce the friction between the shielding member 110 and the support 129, and prolongs the service life of the shielding member 110. The reel 122 is lower than the support 129, so that the support 129 and the shielding member 110 on one end of the reel 122 are in a downward inclined state. In this way, during the rolling process of the shielding member 110, foreign matter on the shielding member 110 can slide along the inclined direction, thereby reducing the residual foreign matter on the shielding member 110 and keeping the shielding member 110 clean.
