[0029] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described 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 are within the scope of protection of this application.

[0030] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "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.

[0031] The electronic device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1, which is a structural diagram of a charging device. The charging device 100 is used to charge the device 300 to be charged. The charging device 100 includes a base 110, a first support member 120 and a second support member 130. The device 300 to be charged is placed on the base 110 for wireless charging. In order to ensure charging efficiency, it is usually necessary to align the coil of the device to be charged 300 with the center position of the coil of the charging device 100. However, the coil heights of different models of devices to be charged are different. The existing method is usually to add one or more pads to the base 110 to adapt to the coil heights of different models of devices to be charged. Equipping a charging device with multiple pads will increase the user's annoyance and reduce the user experience. At the same time, its alignment accuracy is not high.

[0033] In response to the problems in the above-mentioned wireless charging process, an embodiment of the present application provides a charging device. When the device to be charged 300 is placed on the base of the charging device, the charging device can drive the coil to move according to the received height information so that the coil of the charging device is aligned with the coil in the device to be charged 300, thereby realizing automatic alignment of the coil heights of different models of devices to be charged and improving the coil alignment accuracy.

[0034] Please refer to Figure 2, which is a schematic diagram of the structure of the charging device provided in an embodiment of the present application. The charging device 200 includes: a base 210, a first support member 220, a second support member 230, a coil 240, and a drive structure 250; the base 210 is arranged on the first support member 220 for supporting the device 300 to be charged, the first support member 220 is connected to the second support member 230, and there is an angle between the first support member 220 and the second support member 230; the coil 240 is movably arranged in the first support member 220, and the drive structure 250 is arranged in the first support member 220 for driving the coil 240 to move; specifically, the first support member 220 includes a first shell 220a and a second shell 220b, and the coil 240 and the drive structure 250 are arranged in the first support member 220 composed of the first shell 220a and the second shell 220b.

[0035] When the device 300 to be charged is placed on the base 210, the drive structure 250 drives the coil 240 according to the height information received from the charging device 200. This allows the coils of different models to be automatically aligned, improving coil alignment accuracy. Furthermore, the charging device can achieve coil alignment without the need for additional height blocks, thus improving ease of use.

[0036] In a possible implementation, as shown in FIG3 , the driving structure 250 includes a first mounting position 251 and a second mounting position 252 ;

[0037] A screw shaft 251a is mounted on the first mounting position 251. A screw nut 251b is sleeved on the screw shaft 251a and adapted to the screw shaft 251a. The screw nut 251b can rotate around its own axis on the first mounting position 251.

[0038] The screw nut 251b is fixedly connected to the coil 240;

[0039] A motor assembly is installed on the second installation position 252, and the motor assembly is drivingly connected to the screw nut 251b to drive the screw nut 251b to rotate around its own axis.

[0040] In the embodiment of the present application, the motor assembly can be a stepper motor or a DC motor. The type of the motor assembly is not specifically limited herein. When the motor assembly is working, the drive screw nut 251b rotates around its own axis, causing the coil 240 to move up and down along the screw shaft 251a.

[0041] In a possible implementation, in order to ensure the stability of the movement of the coil 240 , the driving structure 250 may be mounted on the track bracket 260 , and the lead screw nut 251 b of the driving structure 250 may be fixedly connected to the coil 240 via a screw 251 c .

[0042] In one possible implementation, the charging device 200 further includes a sliding rheostat 270 having a sliding portion fixedly connected to the coil 240 and configured to slide in conjunction with the sliding portion when the coil 240 moves to change the resistance value of the sliding rheostat 270 .

[0043] The sliding rheostat 270 is connected to the driving structure 250 so that the driving structure 250 determines the movement length of the coil according to the resistance value of the sliding rheostat 270 and stops driving the coil 240 when the movement length is consistent with the height indicated by the height information.

[0044] In an embodiment of the present application, as shown in FIG4 , a limiting hole 241 can be provided at a designated location on the edge of the coil 240. By inserting the sliding portion of the sliding rheostat 270 into the limiting hole 241, a fixed connection between the sliding portion of the sliding rheostat 270 and the coil 240 is achieved. When the coil 240 moves, the sliding portion of the sliding rheostat 270 slides synchronously, and the sliding length of the sliding portion is the same as the movement length of the coil 240. In this way, when the coil 240 moves, the sliding portion slides in conjunction with the sliding portion to change the resistance value of the sliding rheostat 270, so that the drive structure 250 determines the movement length of the coil based on the resistance value of the sliding rheostat 270 and stops driving the coil 240 when the movement length matches the height indicated by the height information. In this way, the consistency of the coil movement length and the received height information can be ensured, further improving the alignment accuracy between the coil of the charging device and the coil of the device to be charged.

[0045] In one possible implementation, a monitoring device 280 is provided on the first support member 220; the monitoring device 280 includes a light-sensing glass 281 and a light-sensing device 282. The light-sensing glass 281 is provided on the contact surface between the first support member 220 and the device to be charged 300, and the light-sensing device 281 is provided on a side of the first support member 220 close to the light-sensing glass 281.

[0046] The light sensing device 281 is electrically connected to the driving structure 250 , so that the driving structure 250 determines that the device to be charged 300 is placed on the base 210 based on the light sensing information collected by the light sensing device 281 .

[0047] In an embodiment of the present application, the monitoring device 280 may be a pressure sensor, an infrared sensor, or the like, and is used to detect whether a device 300 to be charged is placed on the base 210 of the charging device 200. Optionally, the monitoring device 280 may include a light-sensing glass 281 and a light-sensing device 282. As shown in Figures 5a and 5b, the light-sensing glass 281 is disposed on the contact surface between the first support member 220 and the device 300 to be charged, specifically at the center of the contact surface. The light-sensing device 281 is disposed on a side of the first support member 220 near the light-sensing glass 281. The light-sensing device 281 collects light sensing information, such as light intensity and brightness. If the light sensing information meets a preset trigger condition, it is determined that a device 300 to be charged is placed on the base 210 of the charging device 200. The trigger condition may be that the light intensity or brightness is below a preset threshold. In this way, by sensing the placement of the device 300 to be charged on the base 210, the charging device 200 can promptly wirelessly charge the device 300 to be charged, thereby improving wireless charging efficiency.

[0048] In one possible implementation, since the device to be charged 300 may be placed horizontally on the base 210 of the charging device 200, the actual height of the coil of the horizontally placed device to be charged 300 is lower than when the device to be charged 300 is placed vertically on the base 210 of the charging device 200. Therefore, the above-mentioned coil 240 includes an upper coil and a lower coil, and the upper coil is located directly above the lower coil. When the device to be charged 300 is placed vertically on the base 210 of the charging device 200, a wireless link is formed between the upper coil and the coil of the device to be charged 300. The charging device 200 receives height information through the wireless link, and the driving structure 250 drives the upper coil to move according to the height information received by the charging device 200 to adapt to the coil height of the device to be charged 300 when it is placed vertically; when the device to be charged 300 is placed horizontally on the base 210 of the charging device 200, a wireless link is formed between the lower coil and the coil of the device to be charged 300, and the driving structure 250 drives the lower coil to move to the target height to adapt to the coil height of the device to be charged 300 when it is placed horizontally.

[0049] In one possible implementation, a fan 290 is installed inside the charging device 200 and is located below the coil 240. The fan 290 is used to blow air and / or extract heat from the coil 240. This can reduce the temperature of the coil 240 when it is in operation, thereby extending the service life of the charging device 200.

[0050] In a possible implementation, a mainboard 2100 is further provided in the second support member 230 . The mainboard 2100 is used to energize the unpowered coil when the charging device 200 is in a powered-on state.

[0051] As can be seen from the above, an embodiment of the present application provides a charging device, comprising: a base, a first support, a second support, a coil, and a drive structure; the base is arranged on the first support, for supporting the device to be charged, the first support is connected to the second support, and there is an angle between the first support and the second support, the coil is movably arranged in the first support, and the drive structure is arranged in the first support, and the drive structure is used to drive the coil to move; when the device to be charged is placed on the base, the drive structure drives the coil to move according to the height information received by the charging device. In this way, when the device to be charged is placed on the base of the charging device, the charging device can drive the coil to move according to the received height information, so that the coil of the charging device is aligned with the coil in the device to be charged, thereby realizing automatic alignment of the coil heights of different models of devices to be charged, improving the coil alignment accuracy, and at the same time, the charging device can realize coil alignment without the need for additional padding blocks, which can improve the convenience of use.

[0052] The present application also provides a wireless charging alignment method, which can be performed by the charging device 200 provided in the present application. Refer to Figure 6, which is a flow chart of the wireless charging alignment method provided in the present application. The wireless charging alignment method 600 can include the following steps:

[0053] S601: When a device to be charged is placed on a base of the charging device, if a wireless link is formed between a first coil of the charging device and a second coil of the device to be charged, height information of the second coil sent by the device to be charged is received via the wireless link;

[0054] S602: Control the driving structure of the charging device to drive the first coil of the charging device to move according to the height information.

[0055] In the embodiment of the present application, the device to be charged 300 can be a mobile phone or a tablet computer, or a smart watch or a smart bracelet, etc. The device to be charged 300 has at least a receiving coil and a wireless charging function. When the device to be charged 300 is placed on the base 210 of the charging device 200, the first coil (i.e., coil 240) of the charging device 200 is energized to generate a magnetic field. The second coil on the device to be charged 300 generates electromagnetic energy after inducing the magnetic field, forming a wireless link between the first coil and the second coil. Through this wireless link, power or data can be transmitted between the two coils, for example, power transmission is performed by electromagnetic induction, and data transmission is performed by carrier communication. The charging device 200 receives the height information of the second coil sent by the device to be charged 300 through the wireless link, so that the driving structure 250 of the charging device 200 drives the first coil (i.e., coil 240) of the charging device 200 to move according to the height information. Among them, the height information can be the height parameter of the second coil relative to the bottom edge of the device to be charged 300, or it can be the model or size parameter of the device to be charged related to the height of the second coil; the driving structure 210 can be a stepper motor, a DC motor, etc.

[0056] In a possible implementation, in step S601, it may be determined that the device to be charged is placed on the base of the charging device by:

[0057] Obtain light sensing information from a light sensor on a charging device;

[0058] When the light sensing information meets a preset trigger condition, it is determined that the device to be charged is placed on the bottom support of the charging device.

[0059] In this embodiment of the present application, the light sensing information can be light intensity or brightness, and the trigger condition can be when the light intensity or brightness falls below a preset threshold. When the mobile phone waiting for charging device 300 is placed on the base 210 of the charging device 200, the light sensor triggers the wireless charging device 200 to start operating by sensing the light intensity. This allows the wireless charging device to be charged in a timely manner, improving wireless charging efficiency.

[0060] For example, as shown in Figure 7, when a mobile phone is placed on the base 210 of the charging device 200, the infrared light sensor recognizes that an object is approaching. At this time, a wireless link is formed between the Rx coil on the mobile phone and the Tx coil on the charging device. Data and power can be transmitted through this wireless link. The mobile phone sends the position information of the Rx coil to the charging device. The charging device processes the transmitted position information of the Rx coil, determines the motor movement position parameters, and sends a driving signal through the microcontroller unit MCU to drive the motor to move the coil according to the motor movement position parameters, so that the Tx coil of the charging device is aligned with the center position of the Rx coil on the mobile phone, thereby improving the coil alignment accuracy.

[0061] In one possible implementation, the driving structure has multiple travel gears, and the first coil corresponds to different heights at different travel gears. When the device to be charged is placed on the base of the charging device, the driving structure further includes:

[0062] S603: When no wireless link is formed between the first coil and the second coil, controlling the driving structure to drive the first coil of the charging device to move to heights corresponding to the plurality of travel gears according to a preset gear sequence;

[0063] When the driving structure drives the first coil of the charging device to move to a height corresponding to the target travel gear position, the first coil stops moving;

[0064] When the first coil of the charging device is at a height corresponding to the target travel gear position, a wireless link is formed between the first coil and the second coil.

[0065] In an embodiment of the present application, if a wireless link is not formed between the first coil and the second coil, a plurality of travel gears of the drive structure 250 are obtained. The travel gear can be determined based on the moving range of the drive structure 250. For example, the moving range is evenly divided into N sections, each section corresponds to a travel gear, where N is a positive integer. The drive structure 250 is caused to traverse from travel gear 1 to travel gear N in a preset gear sequence within the moving range until a wireless link is formed between the first coil and the second coil, and the movement of the first coil is stopped, and the first coil is maintained at a height corresponding to the target travel gear. Here, travel gear 1 to travel gear N can be traversed according to the size of the travel gear, or it can be traversed in other gear sequences. The gear sequence is not limited here.

[0066] In this way, when a wireless link is not formed between the first coil and the second coil, a wireless link can be formed between the first coil and the second coil by traversing multiple travel gears of the driving structure 250, thereby receiving the height information of the second coil sent by the charging device 300 through the wireless link, realizing automatic alignment between the first coil and the second coil, and improving the coil alignment accuracy.

[0067] In a possible implementation, the method 600 further includes:

[0068] S604: When no device to be charged is placed on the bottom bracket of the charging device, a preset travel gear position among the multiple travel gear positions of the driving structure is obtained, and the driving structure drives the first coil to move to a height corresponding to the preset travel gear position.

[0069] In an embodiment of the present application, if the light sensing information of the photosensitive device cannot meet the preset trigger conditions, it is determined that the device to be charged 300 is not placed on the base 210 of the charging device 200. At this time, the preset travel gear among the multiple travel gears of the driving structure 250 is obtained, so that the driving structure 250 drives the first coil to move to the height corresponding to the preset travel gear, wherein the preset travel gear can be any one of the N travel gears of the driving structure 250. In actual applications, the preset travel gear usually defaults to gear one.

[0070] In one possible implementation, the first coil includes an upper coil and a lower coil. When a wireless link is formed between the second coil on the device to be charged 300 and the upper coil, height information of the second coil sent by the device to be charged 300 is received via the wireless link, and the driving structure 250 of the charging device 200 drives the upper coil of the charging device 200 according to the height information.

[0071] When a wireless link is formed between the second coil and the lower coil on the device to be charged 300 , the driving structure of the charging device drives the lower coil of the charging device 200 to move according to the preset target height information.

[0072] In the embodiment of the present application, since the device to be charged 300 may be placed horizontally on the base 210 of the charging device 200, the actual height of the coil of the horizontally placed device to be charged 300 is lower than when the device to be charged 300 is placed vertically on the base 210 of the charging device 200. At the same time, when different models of devices to be charged 300 are placed horizontally on the charging device 200 for charging, the height information of their coils is not much different. Therefore, when the device to be charged 300 is placed vertically on the base 210 of the charging device 200, a wireless link is formed between the upper coil and the coil of the device to be charged 300, and the charging device 200 receives height information through the wireless link. The driving structure 250 drives the upper coil to move according to the height information received by the charging device 200 to adapt to the coil height of the device to be charged 300 when it is placed vertically; when the device to be charged 300 is placed horizontally on the base 210 of the charging device 200, a wireless link is formed between the lower coil and the coil of the device to be charged 300, and the driving structure 250 drives the lower coil to move to the target height to adapt to the coil height of the device to be charged 300 when it is placed horizontally.

[0073] The following is a detailed description of the wireless charging alignment method:

[0074] As shown in Figure 8, when the charging device 200 is inserted into the charger, the charging device 200 enters the standby state from the off state, and the sensor detects whether there is an object (device to be charged) placed on the base 210. If there is no device to be charged on the base 210, the driving structure (such as a motor) drives the coil to move to the pre-set target travel gear (the default is gear one), and the charging device 200 is in the standby state.

[0075] If a device 300 to be charged is placed on the base 210 of the charging device 200, the system determines whether the charging coil is operating. Specifically, it determines whether a wireless link has been established between the coil on the charging device and the coil on the phone. This wireless link can be used to transmit power or data. If the charging coil is not operating, the system cycles through the N motor travel gears until the charging coil is operating. If the charging coil is operating, the system determines whether the upper or lower coil is operating. If the upper coil is operating, upon receiving a motor position command, the system controls the motor to drive the upper coil according to the motor position command. If the lower coil is operating, the system controls the motor to drive the lower coil according to the motor position command.

[0076] As can be seen from the above, the embodiments of the present application provide a wireless charging alignment method. When a device to be charged is placed on the base of the charging device, if a wireless link is established between the first coil of the charging device and the second coil of the device to be charged, the height information of the second coil sent by the device to be charged is received via the wireless link; the driving structure of the charging device is controlled to drive the first coil of the charging device according to the height information. In this way, the first coil of the charging device can be automatically aligned with the second coil of the device to be charged, improving the coil alignment accuracy. At the same time, the charging device can achieve coil alignment without the need for additional height blocks, which can improve the convenience of users using the charging device.

[0077] Please refer to Figure 9, which is a schematic diagram of the structure of the wireless charging alignment device provided in an embodiment of the present application. The wireless charging alignment device 900 can be applied to the charging device provided in an embodiment of the present application, including:

[0078] The receiving module 910 is configured to receive height information of the second coil on the device to be charged via the wireless link when the device to be charged is placed on the base of the charging device and a wireless link is formed between the first coil of the charging device and the second coil on the device to be charged;

[0079] The control module 920 is configured to control the driving structure of the charging device to drive the first coil of the charging device to move according to the height information.

[0080] In one possible implementation, it can be determined that the device to be charged is placed on the base of the charging device by:

[0081] Obtain light sensing information from a light sensor on a charging device;

[0082] When the light sensing information meets a preset trigger condition, it is determined that the device to be charged is placed on the bottom support of the charging device.

[0083] In one possible implementation, the drive structure has multiple travel gears, and the first coil corresponds to different heights at different travel gears. When the device to be charged is placed on the base of the charging device, the control module 920 is further configured to:

[0084] When no wireless link is formed between the first coil and the second coil, the driving structure is controlled to drive the first coil of the charging device to move to heights corresponding to the plurality of travel gears according to a preset gear sequence;

[0085] When the driving structure drives the first coil of the charging device to move to a height corresponding to the target travel gear position, the first coil stops moving;

[0086] When the first coil of the charging device is at a height corresponding to the target travel gear position, a wireless link is formed between the first coil and the second coil.

[0087] In one possible implementation, the first coil includes an upper coil and a lower coil. When a wireless link is formed between the second coil and the upper coil on the device to be charged, height information of the second coil sent by the device to be charged is received via the wireless link, and the driving structure of the charging device drives the upper coil of the charging device according to the height information.

[0088] When a wireless link is formed between the second coil and the lower coil on the device to be charged, the driving structure of the charging device drives the lower coil of the charging device to move according to the preset target height information.

[0089] As can be seen from the above, the embodiments of the present application provide a wireless charging alignment device, including a receiving module and a control module. When a device to be charged is placed on the base of the charging device, the receiving module receives height information of the second coil of the charging device via the wireless link if a wireless link is established between the first coil of the charging device and the second coil of the charging device. The control module then controls the driving structure of the charging device to drive the first coil of the charging device based on the height information. This allows the first coil of the charging device to automatically align with the second coil of the charging device, improving coil alignment accuracy. Furthermore, the charging device can achieve coil alignment without the need for additional heightening blocks, thereby enhancing user convenience in using the charging device.
