[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The following is a detailed description of the charging device and charging method provided in the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] In view of the problems in the background technology, a wireless charging technology is proposed in the prior art, which can not only realize wireless charging, but also facilitate users to use the device to be charged normally during the charging process. As the wireless charging technology becomes more and more mature, wireless charging devices will gradually be eliminated, which will cause a large number of existing wireless charging devices to be treated as electronic waste, thus leading to the technical problem of waste of resources.

[0027] Based on this, in the embodiment of the present application, by integrating the resonant wireless charging device 200 with the air-to-air charging device, the charging device can be wirelessly charged through the charging position 120 and can also be air-to-air charged through the air-to-air charging device. In this way, the existing resonant wireless charging device 200 can be utilized to avoid treating the normally usable resonant wireless charging device 200 as electronic waste. At the same time, since the charging device also includes an air-to-air charging device, during the charging process, there is no need to place the electronic device in a specific position, so that the user can use the electronic device normally during the charging process.

[0028] See also Figure 1-5 , a charging device provided in an embodiment of the present application, comprising:

[0029] A housing 100, wherein the housing 100 comprises a receiving cavity 110 and a charging position 120 disposed on an outer surface of the housing 100;

[0030] A resonant wireless charging device 200 , wherein the resonant wireless charging device 200 is disposed in the housing 100 , and a discharge end of the resonant wireless charging device 200 is located at the charging position 120 ;

[0031] A wireless charging device, the wireless charging device comprising an antenna assembly 300, wherein the antenna assembly 300 is disposed in the receiving cavity 110;

[0032] A circuit board, wherein the circuit board includes a first charging circuit and a feed source, wherein the first charging circuit is electrically connected to the resonant wireless charging device 200, and the feed source is connected to the antenna assembly 300 to achieve wireless charging.

[0033] See also Figure 2 The charging position 120 can be formed by the inclined surface 140 on the surface of the housing 100 and the support plate 130 at the bottom of the inclined surface 140, and the charging end of the resonant wireless charging device 200 is located on the inclined surface 140. In this way, when the user places an electronic device such as a mobile phone on the charging position 120, the resonant wireless charging device 200 can charge the electronic device. The resonant wireless charging device 200 can be a common resonant wireless charging device 200 in the prior art, which can specifically include a housing and a coil located in the housing.

[0034] The charging device may further include a power cord for connecting to an external power source, for example, the power cord may be a plug, and the charging device may be powered by connecting the plug to an external socket. In addition, the charging device may further include a rechargeable battery, so that the rechargeable battery can store electricity, thereby forming a portable charging device.

[0035] It is understandable that the first charging circuit can supply power to the coil in the resonant wireless charging device 200 to generate resonance, thereby realizing wireless charging of the electronic device. The feed source can output electromagnetic waves and radiate electromagnetic waves outward through the antenna assembly 300, thereby realizing wireless charging of the electronic device.

[0036] It can be understood that the resonant wireless charging device 200 and the air charging device can work simultaneously, that is, different electronic devices can be charged simultaneously by the resonant wireless charging device 200 and the air charging device.

[0037] In this embodiment, since the charging device includes a resonant wireless charging device 200 and an air charging device, both wireless charging through the charging position 120 and air charging through the air charging device can be achieved, thereby facilitating users to use electronic devices during the charging process.

[0038] Optionally, the antenna assembly 300 includes at least two radiation plates, and the radiation plate includes an array antenna layer located on the surface;

[0039] The feed source includes at least two sub-feed sources corresponding to the at least two radiation plates one by one, and one of the radiation plates is electrically connected to a corresponding one of the sub-feed sources.

[0040] In this embodiment, the antenna assembly 300 includes at least two radiating plates, and different radiating plates are respectively connected to different sub-feeders to form different antennas. In this way, the antennas formed by different radiating plates can charge different electronic devices at the same time, thereby achieving the technical effect of simultaneously charging at least two electronic devices through air.

[0041] Optionally, the radiation plate comprises a first end surface and a second end surface facing each other, and the first end surface of the radiation plate and the second end surface of the radiation plate are respectively provided with the array antenna layer.

[0042] In this embodiment, the array antenna layers are respectively provided on two opposite sides of the radiation plate, so that the array antenna layers on two opposite sides of the radiation plate can simultaneously radiate electromagnetic waves outward, thereby improving the effect of air charging. In addition, the array antenna layers on two opposite sides of the radiation plate can also form different antennas respectively to achieve simultaneous charging of different electronic devices.

[0043] Optionally, the array antenna layer includes a first sub-array antenna and a second sub-array antenna, and a polarization direction of the first sub-array antenna is perpendicular to a polarization direction of the second sub-array antenna.

[0044] In this embodiment, the polarization direction of the first subarray antenna is perpendicular to the polarization direction of the second subarray antenna, so that the array antenna layer forms a dual-polarized antenna array structure, thereby radiating electromagnetic waves in different directions to charge electronic devices located in different directions of the charging device.

[0045] Optionally, the radiation panel further includes a circularly polarized synthetic network layer and at least two scanning feed network layers with different angles, the first sub-array antenna is electrically connected to the corresponding sub-feed source through the first network layer, and the second sub-array antenna is electrically connected to the corresponding sub-feed source through the second network layer;

[0046] The first network layer and the second network layer are different network layers in the circularly polarized synthetic network layer and the at least two scanning feeding network layers with different angles.

[0047] The circularly polarized synthetic network layer and at least two scanning feed network layers with different angles can be used to change the propagation direction of the electromagnetic wave transmitted from the feed source to the array antenna layer. In this way, the array antenna layers on both sides of the same radiation board can radiate energy in different directions to realize charging of electronic devices located in different directions of the charging device.

[0048] Specifically, the at least two radiation panels may include a target radiation panel, and the target radiation panel is any radiation panel among the at least two radiation panels. The target radiation panel is electrically connected to the sub-feed corresponding to the target radiation panel through the first network layer, and the second sub-array antenna is electrically connected to the sub-feed corresponding to the target radiation panel through the second network layer.

[0049] In one embodiment of the present application, the radiation board includes: a circular polarization synthetic network layer, a 30-degree scanning feed network layer, a 45-degree scanning feed network layer, and a 60-degree scanning feed network layer. Since array antenna layers are provided on both sides of the radiation board, and each array antenna includes a first sub-array antenna and a second sub-array antenna, that is, a radiation board includes 2 groups of first sub-array antennas and 2 groups of second sub-array antennas. In this way, the 2 groups of first sub-array antennas and the 2 groups of second sub-array antennas can be electrically connected to the corresponding sub-feed sources through different network layers in the circular polarization synthetic network layer, the 30-degree scanning feed network layer, the 45-degree scanning feed network layer, and the 60-degree scanning feed network layer. The radiation board can radiate electromagnetic waves in four different directions to further improve the effect of wireless charging.

[0050] The above-mentioned charging device can charge the same electronic device wirelessly through the antennas corresponding to different network layers, and receive the charging power of the electronic device when different network layers charge the same electronic device. Then, the target network layer can be determined, wherein the target network layer is the network layer with the highest charging power of the electronic device among the antennas corresponding to the above-mentioned network layers. Then, according to the scanning angle of the network layer, the antenna assembly can be controlled to rotate to the corresponding angle to increase the charging power of the charging device to the electronic device.

[0051] Optionally, the antenna assembly 300 is slidably connected to the inner wall of the receiving cavity 110 , and the antenna assembly 300 can be switched between a retracted state and an extended state relative to the receiving cavity 110 .

[0052] It can be understood that when the antenna assembly 300 is in a retracted state, the antenna assembly 300 is accommodated in the accommodation cavity 110 , and when the antenna assembly 300 is in an extended state, the antenna assembly 300 is located outside the accommodation cavity 110 .

[0053] In this embodiment, the antenna assembly 300 is slidably connected to the receiving cavity 110 of the housing 100, so that when air charging is required through the air charging device, the antenna assembly 300 can be extended out of the receiving cavity 110, thereby improving the radiation effect of the antenna assembly 300. When the air charging device is not needed for air charging, the air charging device can be accommodated in the receiving cavity 110, which is conducive to the miniaturization design of the charging device.

[0054] Optionally, the antenna assembly 300 further includes a first slider 346 and a telescopic assembly 340, the at least two radiation plates are respectively connected to the telescopic assemblies 340, a first slideway is provided in the receiving cavity 110, the first slider 346 is slidably connected to the first slideway, and one end of the telescopic assembly 340 is fixedly connected to the first slider 346;

[0055] When the antenna assembly 300 is in the retracted state, the telescopic assembly 340 is retracted, and the at least two radiation plates are stacked;

[0056] When the antenna assembly 300 is in the extended state, the telescopic assembly 340 is extended, and the at least two radiation plates are staggered.

[0057] Specifically, see Figure 5 , the telescopic component 340 can be used to control at least two radiation plates to switch between an overlapping state and a misaligned state. In this way, when the air-to-air charging device is needed for air-to-air charging, the antenna component 300 can be extended out of the receiving cavity 110, and the telescopic component 340 can be extended to make the at least two radiation plates misaligned, thereby increasing the radiation area of ​​the antenna component 300 and improving the radiation effect. When the air-to-air charging device is not needed for air-to-air charging, the air-to-air charging device can be accommodated in the receiving cavity 110, and the telescopic component 340 can be retracted to make the at least two radiation plates stacked, which is conducive to the miniaturization design of the charging device.

[0058] Optionally, see Figure 5 In one embodiment of the present application, the at least two radiation panels include a first radiation panel 310, a second radiation panel 320 and a third radiation panel 330, and the telescopic assembly 340 includes a first strip slide rail 341, a second strip slide rail 342 and a third strip slide rail 343;

[0059] The first bar-shaped slide rail 341 includes a first slide groove 3411 and a first mounting groove 3412 which are arranged in parallel, and the first slide groove 3411 and the first mounting groove 3412 are respectively arranged along the length direction of the first bar-shaped slide rail 341, one end of the first radiation plate 310 is embedded in the first mounting groove 3412, the second bar-shaped slide rail 342 is slidably connected to the first slide groove 3411, and the second bar-shaped slide rail 342 can be extended or retracted relative to the first slide groove 3411;

[0060] The second bar-shaped slide rail 342 includes a second slide groove 3421 and a second mounting groove 3422 arranged in parallel, and the second slide groove 3421 and the second mounting groove 3422 are respectively arranged along the length direction of the second bar-shaped slide rail 342, one end of the second radiation plate 320 is embedded in the second mounting groove 3422, and the third bar-shaped slide rail 343 is slidably connected to the second slide groove 3421, and the third bar-shaped slide rail 343 can be extended or retracted relative to the second slide groove 3421;

[0061] The third strip-shaped slide rail 343 includes a third installation slot 3431 . The third installation slot 3431 is arranged along the length direction of the third strip-shaped slide rail 343 . One end of the third radiation plate 330 is embedded in the third installation slot 3431 .

[0062] Specifically, see Figure 5 When the telescopic assembly 340 needs to be extended, the second bar rail 342 is controlled to extend relative to the first slide slot 3411, and the third bar rail 343 is controlled to extend relative to the second slide slot 3421. When the telescopic assembly 340 needs to be retracted, the second bar rail 342 is controlled to retract relative to the first slide slot 3411, and the third bar rail 343 is controlled to retract relative to the second slide slot 3421.

[0063] Optionally, the first bar-shaped slide rail 341 is rotatably connected to the housing 100 , the second bar-shaped slide rail 342 is rotatably connected to the first bar-shaped slide rail 341 , and the third bar-shaped slide rail 343 is rotatably connected to the second bar-shaped slide rail 342 ;

[0064] When the antenna assembly 300 is in the extended state, the first bar rail 341 can rotate relative to the housing 100 , the second bar rail 342 can rotate relative to the first bar rail 341 , and the third bar rail 343 can rotate relative to the second bar rail 342 .

[0065] Among them, the second bar slide rail 342 and the first bar slide rail 341 can be directly rotatably connected. For example, the first slide groove 3411 of the first bar slide rail 341 can be set to be not output in the cylindrical figure. At the same time, the second bar slide rail 342 is set to be not output in the cylindrical figure, and the second bar slide rail 342 includes a first section and a second section. The second mounting groove 3422 is opened in the first section. When the first section of the second bar slide rail 342 extends out of the first slide groove 3411, the second section of the second bar slide rail 342 is located in the first slide groove 3411. At this time, the second section of the second bar slide rail 342 can rotate relative to the first slide groove 3411, thereby driving the second radiation plate 320 to rotate relative to the first bar slide rail 341, so that the radiation angle of the second radiation plate 320 can be adjusted separately.

[0066] In addition, in another embodiment of the present application, the second strip slide rail 342 and the first strip slide rail 341 can also be connected by a rotating connecting piece. For example, the second strip slide rail 342 can be connected to the first universal joint (not shown in the figure) on the side of the bottom of the accommodating cavity 110. When the second strip slide rail 342 extends out of the first slide groove 3411, the first universal joint is located in the first slide groove 3411. At this time, the second strip slide rail 342 can be freely rotated relative to the first strip slide rail 341 through the first universal joint to further facilitate the individual adjustment of the radiation angle of the second radiation plate 320.

[0067] It can be understood that the third bar slide rail 343 and the second bar slide rail 342 can be directly rotationally connected or rotationally connected via a second universal joint. The specific implementation method can refer to the implementation method of the rotational connection between the second bar slide rail 342 and the first bar slide rail 341. To avoid repetition, it will not be described here.

[0068] Correspondingly, the first bar slide rail 341 and the shell 100 can be directly rotationally connected or rotationally connected through a third universal joint. The specific implementation method can refer to the implementation method of the rotational connection between the second bar slide rail 342 and the first bar slide rail 341 mentioned above. To avoid repetition, it will not be repeated here.

[0069] Optionally, the first slider 346 is provided with a first through hole arranged along the telescopic direction of the antenna assembly 300, and the telescopic assembly 340 includes a rotating rod 344, which is passed through the first through hole, and the rotating rod 344 can rotate relative to the first slider 346 to drive the antenna assembly 300 to rotate.

[0070] Specifically, see Figure 1 In one embodiment of the present application, the first strip rail 341 includes the rotating rod 344, so that during the rotation of the rotating rod 344, the first strip rail 341 can be driven to rotate synchronously, and accordingly, the second strip rail 342 and the third strip rail 343 follow the first strip rail 341 to rotate synchronously, thereby driving at least two radiation plates to rotate, and the radiation plate can change the radiation direction while rotating. In this way, the antenna assembly 300 can be controlled to rotate to the corresponding position according to the position of the electronic device that needs to be charged wirelessly, thereby further improving the effect of wireless charging.

[0071] Optionally, the telescopic assembly 340 further includes a first damping block 345, a second damping block 347 and a washer 348, wherein the first damping block 345 is sleeved on the rotating rod 344, and the first damping block 345 is located on a side of the first slider 346 facing the telescopic assembly 340, the second damping block 347 is fixedly connected to an end surface of the first slider 346 facing the telescopic assembly 340, and the first damping block 345 abuts against the second damping block 347;

[0072] A first annular protrusion 3441 is provided on the surface of the telescopic rod, and the first annular protrusion 3441 is located on the side of the first slider 346 facing away from the telescopic assembly 340. The washer 348 is sleeved on the rotating rod 344, and the washer 348 is arranged between the first slider 346 and the first annular protrusion 3441. The first end face of the washer 348 abuts against the first slider 346, and the second end face of the washer 348 abuts against the first annular protrusion 3441.

[0073] Specifically, the first damping block 345 may be fixedly connected to the rotating rod 344. The second damping block 347 may be formed integrally with the first sliding block 346. The washer 348 may be an elastic washer 348, and the elastic washer 348 is in an elastically compressed state, so that the first damping block 345 and the second damping block 347 may be abutted against each other under the elastic force of the elastic washer 348.

[0074] In this embodiment, by making the first damping block 345 abut against the second damping block 347, when the rotating rod 344 is rotated to a specific position, due to the friction resistance between the first damping block 345 and the second damping block 347, it can be ensured that the position between the rotating rod 344 and the first slider 346 is relatively fixed, thereby achieving position locking of the radiation plate.

[0075] Optionally, the charging device also includes a first driving component and a second driving component, the first driving component and the second driving component are respectively electrically connected to the circuit board, and the first driving component is used to drive the antenna assembly 300 to switch between the retracted state and the extended state, and the second driving component is used to drive the rotating rod 344 to rotate relative to the first slider 346.

[0076] Specifically, the first driving component can be a common electric telescopic device in the prior art, for example, an electric telescopic rod, and the fixed end of the electric telescopic rod can be connected to the housing 100, and the telescopic end of the electric telescopic rod can be connected to the third strip-shaped slide rail 343, so that when the electric telescopic rod is extended, the telescopic component 340 can be extended, and the antenna component 300 can be extended from the receiving cavity 110. Correspondingly, when the electric telescopic rod is retracted, the telescopic component 340 can be shortened, and the antenna component 300 can be retracted into the receiving cavity 110.

[0077] The second driving component may be a motor. Thus, under the driving action of the motor, the rotating rod 344 may be driven to rotate relative to the first slider 346, thereby driving the radiation plate to rotate to adjust the radiation direction of the radiation plate.

[0078] In this embodiment, by setting the first driving component and the second driving component, when wireless charging is required, the antenna component 300 can be driven by the first driving component and the second driving component to move to the corresponding position to improve the effect of wireless charging.

[0079] See also Figure 6 In one embodiment of the present application, the charging device can be connected to a household power strip to achieve continuous power supply to the charging device. When the charging device senses that the first electronic device is in contact with the discharge end of the resonant wireless charging device 200, the resonant wireless charging device 200 can be controlled to wirelessly charge the first electronic device. When the second electronic device sends a wireless charging request to the charging device, the charging device can perform a TCP / IP selection action, and then call the wireless charging protocol to send a confirmation instruction to the second electronic device. After receiving the confirmation instruction, if the second electronic device receives a confirmation operation from the user, it starts the internal antenna charging signal and feeds back the confirmation information to the charging device. The charging device can wirelessly charge the second electronic device according to the power selected by the user in the confirmation information.

[0080] See also Figure 7In another embodiment of the present application, when the charging device senses that the first electronic device is in contact with the discharge end of the resonant wireless charging device 200, the resonant wireless charging device 200 can be controlled to wirelessly charge the first electronic device. When multiple second electronic devices simultaneously send wireless charging requests to the charging device, the charging device can perform a TCP / IP selection action, and then call the wireless charging protocol to send a confirmation instruction to the second electronic device. After receiving the confirmation instruction, if the second electronic device receives the user's confirmation operation, it starts the internal antenna charging signal and feeds back the confirmation information to the charging device. The charging device can simultaneously perform wireless charging on multiple second electronic devices according to the power selected by the user in the confirmation information.

[0081] See also Figure 8 , is a charging method provided in an embodiment of the present application, applied to the charging device described in the above embodiment, the method comprising:

[0082] Step S801: When it is detected that a first electronic device is placed on the charging position 120, control the resonant wireless charging device 200 to wirelessly charge the first electronic device;

[0083] Step S802: upon receiving the wireless charging status information sent by the second electronic device, controlling the wireless charging device to perform wireless charging on the second electronic device.

[0084] In this embodiment, since the charging device includes a resonant wireless charging device 200 and an air charging device, both wireless charging through the charging position 120 and air charging through the air charging device can be achieved, thereby facilitating users to use electronic devices during the charging process.

[0085] Optionally, after controlling the resonant wireless charging device 200 to wirelessly charge the first electronic device, the method further includes:

[0086] When it is detected that the first electronic device is separated from the charging position 120 and the current power of the first electronic device is lower than a preset value, the wireless charging device is controlled to perform wireless charging on the first electronic device.

[0087] Specifically, when the antenna assembly 300 is in the extended state, and it is detected that the first electronic device is separated from the charging position 120, and the current power of the first electronic device is lower than a preset value, the wireless charging device can be controlled to perform wireless charging on the first electronic device. The preset value can be 20% of the total power.

[0088] It can be understood that when the antenna assembly 300 is in a retracted state and it is detected that the first electronic device is separated from the charging position 120, and the current power of the first electronic device is lower than a preset value, the user of the first electronic device needs to actively request to establish a wireless charging connection with the charging device in order to perform wireless charging on the first electronic device.

[0089] Optionally, when receiving the wireless charging status sent by the second electronic device, controlling the wireless charging device to perform wireless charging on the second electronic device includes:

[0090] When receiving the wireless charging status sent by the second electronic device, the antenna assembly of the wireless charging device is controlled to extend relative to the receiving cavity, and the wireless charging device is controlled to perform wireless charging on the second electronic device.

[0091] Specifically, since the antenna assembly has a better radiation effect when it is extended relative to the receiving cavity, based on this, in an embodiment of the present application, when the wireless charging status sent by the second electronic device is received, the antenna assembly is controlled to extend relative to the receiving cavity, and at the same time, the wireless charging device is controlled to perform wireless charging on the second electronic device, thereby further improving the effect of the wireless charging.

[0092] Optionally, after controlling the wireless charging device to perform wireless charging on the second electronic device, the method further includes:

[0093] receiving infrared coded positioning information sent by the second electronic device, where the infrared coded positioning information is used to indicate a current location of the second electronic device;

[0094] Based on the infrared coded positioning information, the antenna assembly 300 is controlled to rotate to a position corresponding to the second electronic device.

[0095] Specifically, see Fig. 9 Since the user may carry the second electronic device with him during the wireless charging of the second electronic device, so that the relative position between the second electronic device and the charging device changes, the second electronic device can poll the charging device to send infrared coded positioning information. After receiving the infrared coded positioning information, the charging device can parse the infrared coded positioning information to determine the current position of the second electronic device, and then control the antenna assembly 300 to rotate to the corresponding position to ensure that the second electronic device always has a higher charging power, thereby further improving the charging effect of wireless charging.
