[0034] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application are only based on the drawings of the present application, and are not specific limitations on the present application.

[0035] Referring to Figures 1-8The application discloses a wireless charger, which comprises a charging transmitting device 100 and a charging receiving device 200, the charging transmitting device comprises a shell 10, a primary coil 11 and a charging input plate 12 arranged in the shell 10, and the primary coil 11 and the charging input plate 12 are connected.

[0036] The charging receiving device comprises a fixing base 1, a charging receiving mechanism and a supporting assembly arranged on the fixing base 1, the charging receiving mechanism comprises a secondary coil 2 and a charging output plate 3 which are connected, the secondary coil 2 is arranged on the supporting assembly, the supporting assembly is movably connected with the fixing base 1, and the secondary coil 2 is driven to be close to the primary coil 11 through the supporting assembly so as to realize wireless charging.

[0037] The charging input plate 12 and the charging output plate 3 are both PCB plates.

[0038] The wireless charger comprises the charging transmitting device and the charging receiving device, and the charging of the equipment can be realized by the close of the two devices. The charging transmitting device is connected with a power supply, current is delivered to the charging input plate, energy coupling transmission is realized through the electromagnetic induction principle of the primary coil, when the primary coil is close to the secondary coil, energy is transmitted to the secondary coil, and finally delivered to the charging output plate, the charging output plate is connected with the equipment, thereby delivering electric energy to the equipment, and wireless charging is realized. The charging receiving device plays a role in electric energy transmission, as long as the charging receiving device is connected with the equipment and close to the charging transmitting device, the charging of the equipment can be realized, a power line is not needed, and the equipment does not need to be disassembled for charging, thereby bringing great convenience to the use of users. Meanwhile, the normal operation of the equipment is not affected due to the traction of the power line.

[0039] Further, as shown in the figure, Figures 2-3 The charging receiving mechanism further comprises a power management chip 4, and the secondary coil 2, the power management chip 4 and the charging output plate 3 are sequentially connected. The power management chip is a chip for the responsibility of transformation, distribution, detection and other electric energy management of electric energy, and adopts an existing technical structure, which will not be described in detail here.

[0040] Specifically, as shown in the figure, Figures 3-4 The fixing base 1 is provided with a receiving cavity 1a and an output cavity 1b which are connected in communication, the supporting assembly is arranged in the receiving cavity 1a, that is, the secondary coil 2 and the power management chip 4 are arranged in the receiving cavity 1a, and the charging output plate 3 is arranged in the output cavity 1b.

[0041] Preferably, as shown in the figure, Figures 2-3The support assembly includes a support frame 6 arranged in the receiving cavity 1a and capable of extending out of the fixing base 1. The support frame 6 is provided with a containing cavity 61 penetrating through the two end faces thereof. The secondary coil 2 and the power management chip 4 are arranged in the containing cavity 61. That is, the support frame 6 and the fixing base 1 are movably connected, and the support frame 6 can extend out of the fixing base 1. Through the movement of the support frame, the secondary coil and the power management chip can be moved together. When the charging receiving device is close to the charging transmitting device, the secondary coil is close to the charging transmitting device under the driving of the support frame, that is, close to the primary coil, so as to ensure the charging efficiency. Through the telescopic structure between the support frame and the fixing base, when the charging receiving device moves transversely to the charging transmitting device, the friction and collision can be avoided, so that the charging receiving device and the charging transmitting device cannot be completely attached, the charging cannot be achieved, or the charging effect is not ideal, and the like. For example, the charging transmitting device is installed on the frame of a window, and the charging receiving device is installed on a window sash. When the window sash is pushed leftward and rightward along the frame, the charging receiving device moves from the side of the charging transmitting device to the front. If the support frame cannot move, the support frame will collide with the charging transmitting device, which can damage the wireless charger and hinder the pushing and pulling of the window sash and damage the window. Therefore, the movable support frame can avoid the above problems.

[0042] As shown in Figure 2 , 5 , the outer end face of the support frame 6 is provided with an input port 62, and the inner end face is provided with a connecting port 63. The input port 62, the containing cavity 61, the connecting port 63 and the receiving cavity 1a are sequentially communicated. The connecting line of the power management chip passes through the connecting port from the containing cavity, and then extends to the output cavity from the receiving cavity to be connected with the charging output plate. The input port is provided with an input touch plate, and the secondary coil is arranged at the back of the input touch plate. Preferably, the input touch plate 68 is made of glass. More preferably, the glass is organic glass, which can ensure effective energy transmission. The position of the input touch plate in the support frame is the position of the secondary coil. The input touch plate needs to be attached to the corresponding position of the charging transmitting device to ensure that the secondary coil is close to the primary coil, so as to effectively ensure the effective charging.

[0043] Preferably, as shown in Figures 2-4 , the fixing base 1 is provided with a cover 5. The cover 5, the fixing base 1 and the support frame 6 form the receiving cavity 1a therebetween. The cover 5 and the fixing base 1 form the output cavity 1b therebetween. The cover can close the inside of the fixing base, so as to achieve the purposes of dustproof, waterproof and foreign matter prevention. More preferably, the inner side wall of the output cavity 1b is provided with a buckle block 1d, and the inner side wall of the cover 5 is provided with a clamping hook 55. The clamping hook 55 is clamped on the buckle block 1d. Through the cooperation of the buckle block and the clamping hook, the cover can be easily installed and fixed on the fixing base, which is simple in structure and easy to install.

[0044] Preferably, asFigures 4-5 As shown, the inner wall of the receiving cavity 1a is provided with a limit slot 1c, and the side wall of the support frame 6 is provided with a limit hook 65, which is locked in the limit slot 1c to prevent the support frame 6 from being separated from the fixed base 1. The cooperation between the limit slot and the limit hook limits the movement of the support frame, preventing the support frame from being separated from the fixed base during movement.

[0045] Preferably, if Figures 5-6 As shown, the cover 5 is provided with a first vent 53 communicating with the receiving cavity 1a, and the side wall of the support frame 6 is provided with a second vent 64 communicating with the accommodating cavity 61. The first vent and the support frame are arranged opposite each other. During the movement of the support frame, external air can enter the fixed base through the first and second vents, and air inside the fixed base can also escape through the first and second vents, thereby balancing the air pressure inside and outside the fixed base and ensuring normal movement of the support frame.

[0046] Preferably, if Figure 6 As shown, the cover 5 is provided with a light hole 56, through which the user can see the flashing of the light on the charging output plate, thereby knowing the working status of the wireless charger.

[0047] In addition, if Figure 7 As shown, the housing 10 is provided with an output touch panel 13, and the primary coil 11 is provided on the back of the output touch panel 13. During charging, the output touch panel and the input touch panel are kept as close as possible, and the distance between the primary coil and the secondary coil is shortened to ensure wireless charging.

[0048] Further, if Figures 2-3 As shown in Figures 7 and 7, the inner wall of the output touch panel 13 is provided with a first magnetic member 7, the inner wall of the cover 5 is provided with a second magnetic member 8, and the inner wall of the support frame 6 is provided with a third magnetic member 9. The suction force of the first magnetic member 7 is greater than the suction force of the second magnetic member 8, and the suction force of the second magnetic member 8 is greater than the suction force of the third magnetic member 9. The first magnetic member 7, the second magnetic member 8 and the third magnetic member 9 are all magnets. The arrangement of the first magnetic member and the third magnetic member is to use the mutual attraction force between the magnets to make the support frame close to the charging transmitter device close to the output touch panel, even if the output touch panel and the input touch panel always remain in contact, to ensure that the charging transmitter and the charging receiver are not separated and can be completely contacted during the charging process, so that the distance between the primary coil and the secondary coil is the shortest, ensuring that the wireless charging effect is in the best state.

[0049] Preferably, if Figure 7As shown, the first magnetic member 7 is fixedly installed on the inner wall of the output touch plate 13 through the fixing sleeve 14, and the first magnetic member 7 is arranged along the circumference of the output touch plate 13, that is, the first magnetic member is arranged corresponding to the third magnetic member, so as to ensure that the input touch plate and the output touch plate are effectively attracted and attached, and further ensure the reliability and effectiveness of wireless charging. More preferably, the primary coil 11 is arranged on the fixing sleeve 14.

[0050] When charging is not needed, the user can separate the charging transmitting device and the charging receiving device by moving the movable sector, and the support frame can still be in the position attached to the output touch plate, and even move outwardly from the fixed seat due to the inertia of the suction force. Thus, in the process of moving the movable sector, the support frame can be in contact with the frame body and generate friction, thereby damaging the support frame and the input touch plate. Therefore, in order to avoid the above situation, the second magnetic member is arranged on the cover and arranged opposite to the third magnetic member. After the charging transmitting device and the charging receiving device are separated, the third magnetic member is no longer subjected to the suction force of the first magnetic member, but subjected to the suction force of the second magnetic member, so as to move the support frame into the receiving cavity, and retract the support frame into the fixed seat as a whole and keep this state. In this way, in the moving process of the charging receiving device, the support frame will not move randomly, will not collide with the frame body, and will not affect the normal movement of the movable sector.

[0051] Preferably, as shown in Figures 2-3 , 6, the inner wall of the cover 5 is provided with a first installation slot 51, and the second magnetic member 8 is arranged in the first installation slot 51; the cover 5 is provided with a cover sealing member 52 fixedly connected with the cover 5, and the cover sealing member 52 covers the opening of the first installation slot 51, so as to fix the second magnetic member 8 in the first installation slot 51. The cover is provided with the first installation slot for installing the second magnetic member, and the second magnetic member is fixedly arranged in the first installation slot by the cover sealing member, so as to fix the second magnetic member on the cover. The cover and the cover sealing member are fixedly connected by fasteners. More preferably, the cover 5 is further provided with a limiting column 54, and the limiting column 54 is arranged through the cover sealing member 52, so as to facilitate the positioning of the cover sealing member on the cover, thereby facilitating the installation.

[0052] More preferably, the first ventilation hole 53 is arranged in an array, the first installation slot 51 is arranged along the circumference of the first ventilation hole 53, the cover sealing member 52 is provided with a cover through hole 521, and the first ventilation hole 53 communicates with the receiving cavity 1a through the cover through hole 521, so as to avoid the cover sealing member from blocking the first ventilation hole and ensure the smooth flow of gas.

[0053] Preferably, as shown in Figures 2-3The inner side wall of the support frame 6 is provided with a second mounting groove 66, and the third magnetic member 9 is arranged in the second mounting groove 66; the support frame 6 is provided with a frame sealing member 67 fixedly connected with the support frame 6, and the frame sealing member 67 covers the opening of the second mounting groove 66, so as to fix the third magnetic member 9 in the second mounting groove 66. The second mounting groove for mounting the third magnetic member is arranged on the support frame, and the third magnetic member is fixedly arranged in the second mounting groove by the frame sealing member, so as to fix the third magnetic member on the support frame. The support frame and the frame sealing member are fixedly connected by fasteners.

[0054] More preferably, as shown in Figure 5 The second mounting groove 66 is arranged along the circumference of the containing cavity 61, the frame sealing member 67 is provided with a frame through hole 671, and the containing cavity 61 is communicated with the receiving cavity 1a through the frame through hole 671. Therefore, the first through hole, the cover through hole, the receiving cavity, the frame through hole, the containing cavity and the second air hole are communicated in sequence, so that the gas can flow smoothly during the movement of the support frame, thereby ensuring the normal movement of the support frame.

[0055] The working principle of the wireless charger is that the charging transmitting device 100 is connected with the commercial power, that is, the charging input board 12 is connected with the commercial power, the adapter reduces and rectifies 220V alternating current into 5V direct current to be delivered to the charging input board 12, and the primary coil 11 performs energy coupling transmission through the electromagnetic induction principle. The charging transmitting device 100 and the charging receiving device 200 are close to each other, and the output contact plate 13 and the input contact plate 68 are attached. The primary coil 11 converts electric energy into magnetic energy and transmits the magnetic energy to the secondary coil 2, and the secondary coil 2 converts the received magnetic energy into electric energy, so that the energy transmission is realized. The transmitted electric energy is processed by the power management chip 4 and becomes 12V direct current output to the charging output board 3, so as to charge the charging battery of the to-be-charged mechanism 500.

[0056] It should be noted that the adapter is not shown in the drawings, and the commercial power is delivered to the charging input board after being reduced in voltage. The adapter adopts the prior art structure, and will not be described in detail here.

[0057] Correspondingly, referring to Figure 8The application further discloses a sunshade device, which comprises a frame 300, a movable fan body 400, a mechanism to be charged 500 and the wireless charger.

Generally, the solar panel is connected with the mechanism to be charged. The solar panel converts light energy into electric energy to provide electric power for the mechanism to be charged. When the light energy is insufficient, for example, on a cloudy day or rainy day, the mechanism to be charged is connected with the charging receiving device. Then, the movable fan body is moved to make the charging receiving device on the movable fan body close to the charging transmitting device, so that the output touch plate and the input touch plate are attached to each other, and the mechanism to be charged can be charged. After the charging is completed, the movable fan body is moved to separate the charging receiving device on the movable fan body from the charging transmitting device.

[0059] Specifically, the wireless charger of the application can be applied to a solar-driven electric roller shutter.
