[0066] To more clearly illustrate the technical solutions of the embodiments in this specification, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this specification. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0067] It should be understood that the terms “system,” “device,” “unit,” and / or “module” used herein are one way to distinguish different components, elements, parts, sections, or assemblies at different levels. However, if other terms can achieve the same purpose, they may be replaced by other expressions.

[0068] As indicated in this specification and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" do not specifically refer to the singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0069] Flowcharts are used in this specification to illustrate the operations performed by the system according to embodiments of this specification. It should be understood that the preceding or following operations are not necessarily performed in exact order. Instead, the steps can be processed in reverse order or simultaneously. Furthermore, other operations can be added to these processes, or one or more steps can be removed from them.

[0070] Batteries are common components in many devices; for example, smart door locks require batteries to power them. When the battery is low, it needs to be removed and replaced, causing inconvenience for users. The emergence of photoelectric conversion modules has solved this problem of frequent battery replacements.

[0071] A photoelectric conversion module is a semiconductor device that converts light energy into electrical energy. Photoelectric conversion modules include photovoltaic cells (such as silicon-based photovoltaic cells, gallium arsenide photovoltaic cells, etc.) and photovoltaic cell arrays. A photoelectric conversion module has a photosensitive surface for receiving a charging beam. When the energy storage device connected to the photoelectric conversion module is low on power and needs recharging, a charging beam emitted by a charging beam emitting unit (e.g., a light source emitter) illuminates the photosensitive surface of the photoelectric conversion module. After receiving the charging beam from the light source emitter, the photoelectric conversion module converts the light energy into electrical energy to charge the energy storage device, thus achieving the purpose of charging.

[0072] Figure 1 is a schematic diagram of an application scenario of a wireless charging device according to some embodiments of this specification.

[0073] In some embodiments, as shown in FIG1, the wireless charging device 100 includes a receiver 10 and a transmitter 20. The transmitter includes a charging beam emitting unit. The receiver includes a photoelectric conversion module. The photoelectric conversion module is used to convert the charging beam emitted by the charging beam emitting unit into a photoelectric conversion signal.

[0074] The receiver is the component in a wireless charging device that receives light energy and converts it into electrical energy.

[0075] The receiving end can receive user commands generated by smart terminals such as mobile phones, iPads, or smart wearable devices based on user operations, and convert the user commands into instructions (such as first control instructions and / or second control instructions) recognizable by the charging beam emitting unit and / or the visible beam emitting unit, so as to control the charging beam emitting unit and / or the visible beam emitting unit to perform relevant actions. In some embodiments, the receiving end further includes a charging circuit and an energy storage device. The charging circuit can convert the photoelectric conversion signal output by the photoelectric conversion module into a charging signal that matches the energy storage device. For example, the charging signal can be charging power, charging voltage, and charging current, etc., and provide the charging signal to the energy storage device to charge the energy storage device.

[0076] In some embodiments, the receiving end may further include a power management module. The power management module is used to acquire information such as the remaining power, charging status, and temperature of the energy storage device connected to the photoelectric conversion module.

[0077] The transmitter refers to the component in a wireless charging device that emits a light beam. For example, the transmitter includes a laser, a transmitting circuit, etc. In some embodiments, as shown in Figures 20 to 24 below, the transmitter also includes a housing, a collimating lens, etc.

[0078] A charging beam emitting unit is a device capable of emitting a beam of light for energy transfer. For example, a charging beam emitting unit includes a charging beam emitter (also called a light source, such as light source 1211 shown in Figure 12), an infrared (IR) laser, an ultraviolet (UV) LED, or a laser, etc. The charging beam emitting unit is used to emit a charging beam. The charging beam can be invisible light (e.g., infrared light, ultraviolet light), a near-infrared beam, or visible light in a specific wavelength band.

[0079] Infrared light refers to light waves with wavelengths ranging from approximately 0.76 micrometers to 1000 micrometers, falling between red light (the longest wavelength of visible light is approximately 0.76 micrometers) and microwaves (wavelength > 1 mm).

[0080] In some embodiments, the charging beam emitting unit includes a charging beam emitter. Exemplarily, the charging beam emitter can be an infrared laser light source or an infrared LED light source. The charging beam emitted by the charging beam emitter is an infrared beam, and the photoelectric conversion module can convert the received infrared light signal into an electrical signal to obtain a photoelectric conversion signal. The operating wavelength range of the photoelectric conversion module matches the wavelength of the infrared beam emitted by the charging beam emitter. For example, if the charging beam emitter is an infrared laser light source, and the emitted charging beam is an infrared laser beam, then the operating wavelength range of the photoelectric conversion module covers the wavelength of that infrared laser beam.

[0081] In some embodiments, the charging beam emitting unit further includes a receiving module, a control unit, and a driving module. The receiving module can receive instructions sent by a receiving end, and the control unit can, in response to the instructions sent by the receiving end, control the current of the driving module, thereby controlling the power of the charging beam emitting unit, and / or, in response to the instructions sent by the receiving end, directly control the on / off state of the charging beam emitting unit. In some embodiments, the control unit of the charging beam emitting unit may refer to a processor disposed on the transmitting end of the wireless charging device (or disposed on the charging beam emitting unit).

[0082] For example, when the receiving module receives a second stop charging command from the receiving end, the control unit responds to the second stop charging command by turning off the charging beam emitting unit (such as a light source) or controlling the drive module to drive the charging beam emitting unit to emit a charging beam at zero power, so that the wireless charging device enters a stop charging state. When the receiving module receives a pre-charging command from the receiving end, the control unit responds to the pre-charging command by controlling the drive module to drive the charging beam emitting unit to emit a charging beam at a lower first power, so that the wireless charging device enters a pre-charging state. When the receiving module receives a charging command from the receiving end, the control unit responds to the charging command by controlling the drive module to drive the charging beam emitting unit to emit a charging beam at a higher second power, so that the wireless charging device enters a charging state.

[0083] As an example only, as shown in Figure 1, a wireless charging device is used to charge a door lock. The door lock is equipped with a receiver, which includes a photoelectric conversion module. A transmitter is installed on the ceiling of the room. After the receiver receives the light emitted by the transmitter, the photoelectric conversion module converts the light signal into electrical energy and transmits the electrical energy to an energy storage device (such as a lithium battery or a refrigerated battery).

[0084] In some embodiments, the transmitter further includes a visible beam emitting unit. In some embodiments, the visible beam emitting unit is used to emit a visible beam to adjust the relative position of the transmitter and the receiver.

[0085] A visible light beam emitting unit is a device capable of emitting a beam of light in the visible light band. The visible light band can include red, orange, yellow, green, cyan, blue, and violet light. The color of visible light can be red, green, or yellow, etc. For example, a visible light beam emitting unit includes a visible light LED, a visible light laser diode, etc. To ensure beam concentration, a laser emitter can be used in the visible light beam emitting unit. In some embodiments, a visible light beam emitting unit may include one or more visible light beam emitters.

[0086] The visible light beam emitted by the visible light beam emitting unit can form a visible light spot that is recognizable to the human eye on the surface of an object. For example, a visible light spot is a light spot of a certain area that can be seen by the human eye when the visible light beam shines on the surface of the receiving end.

[0087] The user or control system can adjust the emission angle of the charging beam emitting unit based on the position of the visible light spot, so that the emitting end can be aligned with the receiving end (or photoelectric conversion module). Alignment between the emitting and receiving ends improves the charging efficiency of the photoelectric conversion module.

[0088] When the transmitter and photoelectric conversion module (or receiver) are perfectly aligned, the photoelectric conversion module receives the most light, achieving maximum charging efficiency. For photoelectric conversion modules that use invisible light for charging, such as receivers using infrared or ultraviolet light, or energy storage devices electrically connected to the receiver, aligning the transmitter and receiver is difficult because invisible light is not visible to the naked eye. This makes it impossible to determine the location of the charging beam emitted by the transmitter, resulting in low charging efficiency for the photoelectric conversion module.

[0089] It should be understood that the wireless charging device shown in Figure 1 can also be applied to various devices that require charging, such as smart door locks, smart trash cans, and smart furniture. It should be noted that the above description of the wireless charging device is for convenience only and should not limit this specification to the scope of the illustrated embodiments. It is understood that those skilled in the art, after understanding the principle of this system, may arbitrarily combine the various modules or construct subsystems connected to other modules without departing from this principle.

[0090] Some embodiments of this specification also provide a control system for a wireless charging device. In some embodiments, the control system for a wireless charging device may include one or more processors.

[0091] Some embodiments of this specification also provide a control method for a wireless charging device.

[0092] In some embodiments, the executing entity of the control methods 200, 500, and 1700 of the wireless charging device may be a control system, control unit, processor, and / or terminal device of the wireless charging device. The following description only illustrates the steps of a processor executing any method embodiment provided in this specification.

[0093] The processor can process data, information and / or processing results obtained from other devices or system components, and execute program instructions based on such data, information and / or processing results to perform one or more functions described in this specification.

[0094] In some embodiments, the plurality of processors may include any one or more of the following: a processor disposed on a server; a processor (or control unit) disposed on the transmitter and / or receiver of a wireless charging device; and a processor disposed on a terminal device.

[0095] In some embodiments, the processor is configured to control the visible beam emitting unit to emit a visible beam based on a first control instruction until the emitting end and the receiving end are aligned.

[0096] In some embodiments, the processor is configured to control the charging beam emitting unit to emit or stop emitting a charging beam based on a second control instruction.

[0097] In some embodiments, the processor is configured to:

[0098] In response to the wireless charging device meeting the charging protection conditions, a second control command is generated to control the charging beam emitting unit to stop emitting the charging beam.

[0099] In response to the wireless charging device meeting the conditions for resuming charging, a second control command is generated to control the charging beam emitting unit to emit a charging beam at a first power.

[0100] In response to the wireless charging device meeting normal charging conditions, a second control command is generated to control the charging beam emitting unit to emit a charging beam at a second power, which is greater than the first power.

[0101] In some embodiments, the processor is configured to: when the wireless charging device meets a preset interruption condition, generate a first stop charging command through the receiver, the preset interruption condition including a stop charging condition and / or the wireless charging device being in a standby state; in response to the transmitter receiving the first stop charging command, control the transmitter to block the charging beam emitting unit through a blocking member to prevent the charging beam from illuminating the photoelectric conversion module.

[0102] For more information on this section, please refer to the descriptions in Figures 11 through 19.

[0103] The first control command is a command used to control the visible beam emitting unit. The first control command can determine whether to emit a visible beam, the brightness of the emitted visible beam, and adjust the emitting end, etc. For example, the first control command may include: a charging alignment command, an alignment completion command, and a command to turn off the visible beam emitting unit, etc. For example, adjusting the emitting end includes adjusting an angle adjustment component to adjust the relative position of the emitting end and the receiving end.

[0104] The second control command refers to the command used to control the charging beam emitting unit. The second control command may include commands to launch or stop the charging beam emitting unit, and commands to control the charging beam emitting unit to launch the charging beam based on the emission power. For example, the second control command may include: a stop charging command, a pre-charging command, a normal charging command, a charging interruption command, etc.

[0105] The second and first control commands can be issued by the processor of the wireless charging device, user input, or an external management system. For example, the processor can automatically generate the second and / or first control commands based on whether the wireless charging device meets preset conditions. As an example only, preset conditions may include charging protection conditions; the processor can automatically generate a second control command to control the charging beam emitting unit to stop emitting the charging beam in response to the wireless charging device meeting these conditions. As another example, a user can trigger operations such as "start alignment" or "start charging" via a mobile terminal or device panel, thereby triggering the second and first control commands.

[0106] For more information on the second and first control commands, please refer to other parts of this specification, such as Figures 12-21 and their related descriptions.

[0107] In some embodiments of this specification, the first control command enables efficient and precise charging alignment. The second control command provides hierarchical dynamic charging status management and multiple layers of charging safety protection. Therefore, the control method for wireless charging devices, through intelligent command management, can improve charging efficiency and charging safety.

[0108] In some embodiments, the charging beam emitting unit and the visible beam emitting unit have a preset relative positional relationship. That is, the physical installation position and / or optical path design of the visible beam emitting unit and the charging beam emitting unit are fixed, so that the visible beam and the charging beam form a fixed relative angle or pointing relationship in space. For example, when the overall emission direction of the emitting end is adjusted, the visible beam and the charging beam will move together in a predetermined relative relationship; thereby ensuring that the position of the visible light spot can accurately indicate the irradiation position of the charging beam. The preset relative positional relationship between the visible beam emitting unit and the charging beam emitting unit can be achieved through mechanical fixation, integrated optical design, etc.

[0109] In some embodiments, a visible light beam forms a visible light spot after illuminating the area where the receiver is located. The location of the visible light spot can be on the photoelectric conversion module or in an area outside the photoelectric conversion module.

[0110] For more information on the transmitter, visible beam emitting unit, etc., please refer to other parts of this specification, such as Figures 20-24 and their related descriptions.

[0111] Since the emission angles of the visible beam emitting unit and the charging beam emitting unit are related, the user or processor can adjust the emission angle of the emitting end by observing the position of the visible beam spot, thereby aligning the charging beam with the receiving end (or photoelectric conversion module).

[0112] Figure 2 is an exemplary flowchart of a control method according to some embodiments of this specification. In some embodiments, process 200 may be implemented in response to a first control command being a charging alignment command. In some embodiments, process 200 may be executed by a processor. As shown in Figure 2, process 200 includes the following steps 210 and 220.

[0113] Step 210: Control the visible beam emitting unit to emit a visible beam, and the visible beam forms a visible spot after illuminating the area where the receiving end is located.

[0114] In some embodiments, the processor can determine the first control command as a charging alignment command in various ways. For example, when the photoelectric conversion module is first started or the wireless charging device is first installed, the processor automatically generates the first control command as a charging alignment command. Another example is that the processor issues a charging alignment command at a preset frequency (e.g., monthly). Yet another example is that the user manually triggers the "charging alignment" function through the device interface or an app, thereby triggering the charging alignment command. Yet another example is that the processor triggers the charging alignment command when it detects an abnormal decrease in the intensity of the charging beam received by the photoelectric conversion module during charging; an abnormal decrease in the intensity of the received charging beam may indicate that the alignment state has shifted and realignment is required.

[0115] The processor can control the visible beam emitting unit to emit visible light at a preset emission power. Since the visible beam emitting unit is only used for charging alignment, it can be controlled to emit visible light at a preset low power. That is, the preset emission power is less than the rated power, thus reducing energy consumption. For example, the preset emission power can be 10% or 20% of the rated power.

[0116] Step 220: Adjust the transmitter until the position of the visible light spot is at a preset position, which is used to characterize the area where the photoelectric conversion module is located.

[0117] In some embodiments, the preset position is the area where the photoelectric conversion module is located or the photosensitive surface of the photoelectric conversion module. For example, the preset position may refer to the location of the photosensitive surface of the photoelectric conversion module. In other embodiments, the preset position is another location in the area where the photoelectric conversion module is located in the receiver. For example, as shown in FIG6, the preset position is the location of the visible light spot, and the photoelectric conversion module is located between two visible light spots.

[0118] The processor can determine the position of the visible light spot in several ways. For example, the processor can acquire images of the area where the receiving end is located using an image acquisition device (such as a camera), analyze the image using image processing algorithms, and identify and determine the position of the visible light spot. The image acquisition device can be located at the transmitting end. Alternatively, the user can observe the position of the visible light spot with their naked eye and manually adjust the transmitting end.

[0119] The processor can move the visible light spot by adjusting the emission angle and / or orientation of the transmitter (such as adjusting the angle adjustment component inside the transmitter).

[0120] The processor (or user) can determine whether the visible light spot is at the preset position based on the degree of matching between the real-time position of the visible light spot and the preset position; thus, it can determine whether the transmitter and receiver are aligned. If they are not aligned, the transmitter is continuously adjusted until the visible light spot is at the preset position.

[0121] It should be noted that the above description of process 200 is for illustrative purposes only and does not limit the scope of this specification. Those skilled in the art can make various modifications and changes to process 200 under the guidance of this specification. However, these modifications and changes remain within the scope of this specification.

[0122] In some embodiments, after adjusting the emitting end until the position of the visible light spot is at a preset position, the control method further includes: controlling the visible light beam emitting unit to turn off; and controlling the charging beam emitting unit to emit a charging beam at a preset power to charge the photoelectric conversion module.

[0123] For example, the preset power is the initial charging power, and the charging beam emitting unit charges the photoelectric conversion module according to the initial charging power. Alternatively, the preset power could be the rated power, etc., and there are no restrictions here.

[0124] If the visible light spot is in the preset position, there is no need to adjust the illumination angle of the transmitter.

[0125] During charging, the charging power of the charging beam emitting unit can be adjusted. For example, the charging power may include a first power and a second power. A second control command can be used to control the charging beam emitting unit to emit a charging beam at the first power or the second power. For more information on the first power and the second power, please refer to other parts of this specification, such as Figures 12-19 and their related descriptions.

[0126] In some embodiments, a charging beam forms a charging spot after illuminating the area where the receiver is located. The charging beam emitting unit and the visible beam emitting unit have a preset relative positional relationship, so that the position of the visible spot is adjacent to or at least partially overlaps with the position of the charging spot.

[0127] The charging spot refers to the invisible spot formed when the charging beam illuminates the photoelectric conversion module. The charging spot corresponds to the illumination area of ​​the electric beam emitting unit in the receiving end region.

[0128] The preset relative position relationship refers to the pre-set positional relationship between the charging beam emitting unit and the visible beam emitting unit. For example, if the charging beam emitting unit is located to the left of the visible beam emitting unit, then the charging beam will be positioned to the left of the visible light spot. The preset relative position relationship can determine whether the position of the charging beam is aligned with the photoelectric conversion module.

[0129] The illumination area of ​​the charging beam emitting unit in the receiving end region (hereinafter referred to as the illumination area of ​​the charging beam) refers to the area where the charging beam actually illuminates the receiving end. It can be understood that when the illumination area of ​​the charging beam emitting unit in the receiving end region completely covers the preset position, the charging beam can be considered to be aligned with the photoelectric conversion module.

[0130] The adjacency of the visible light spot to the illumination area of ​​the charging beam means that the visible light spot and the illumination area of ​​the charging beam are spatially adjacent. For example, when the visible light spot falls on a certain area of ​​the receiver, the illumination area of ​​the charging beam is adjacent to the visible light spot. For example, the visible light spot and the illumination area of ​​the charging beam share a portion of the boundary line (as shown in Figure 9). Another example is that when the visible light spot falls on a certain area of ​​the receiver, the illumination area of ​​the charging beam is adjacent to the visible light spot, but their boundary lines are at a certain distance, which does not exceed a set threshold (as shown in Figures 6 and 10).

[0131] The fact that the position of the visible light spot at least partially overlaps with the area illuminated by the charging beam means that the visible light spot at least partially overlaps with the area illuminated by the charging beam in space.

[0132] Figure 3 is a schematic diagram showing the positional relationship between the infrared light emitter and the collimating lens according to some embodiments of this specification.

[0133] In some embodiments, the charging beam emitting unit includes multiple charging beam emitters. The charging beam emitters can be charging light emitting lamps. In some embodiments, the emitting end is also provided with a collimating lens. A collimating lens is an optical element used to convert divergent light rays into parallel beams. For example, a collimating lens is installed at the front end of the charging beam emitter, and the focal point of the collimating lens corresponds to the charging beam emitter (as shown in Figure 3). The relative positions of the charging beam emitter and the collimating lens are fixed, and the light emitted by the charging beam emitter exits after passing through the collimating lens. The focal point of the collimating lens corresponding to the charging beam emitter means that the light emission point (or light center) of the charging beam emitter coincides with or is very close to the focal point of the collimating lens in space, so as to achieve the collimation purpose of "converting divergent light rays into parallel beams". As shown in Figures 1 to 3, taking an infrared light emitter as an example, the infrared light emitted by the infrared light emitter forms an invisible infrared light spot after passing through the collimating lens.

[0134] In some embodiments, the visible beam emitting unit may include multiple visible beam emitters; the visible beam emitters may be visible light emitting lamps. When adjusting the illumination angle of the emitting end, since the visible beam emitting unit and collimating lens are located in the emitting end, and the relative positions of the visible beam emitting unit and the charging beam emitter are fixed, the charging beam emitter and / or collimating lens also move with the emitting end. After the emitting end and the receiving end are aligned, the light emitted by the charging beam emitter can cover the photoelectric conversion module.

[0135] Figure 4 is a schematic diagram showing the positional relationship between the charging beam emitting unit and the visible beam emitting unit according to some embodiments of this specification. Figure 5 is a schematic diagram showing the positional arrangement of the charging beam emitting unit, the visible beam emitting unit, and the collimating lens according to some embodiments of this specification. Figure 6 is a schematic diagram showing the position of the light spot when the charging beam emitting unit and the visible beam emitting unit are arranged side by side according to some embodiments of this specification.

[0136] In some embodiments, as shown in Figures 4 to 6, the visible beam emitting unit includes two sets of visible beam emitting subunits, and the visible light spot includes a first light spot and a second light spot. The visible beam emitted by the first set of visible beam emitting subunits forms the first light spot. The visible beam emitted by the second set of visible beam emitting subunits forms the second light spot.

[0137] In some embodiments, the control method further includes: adjusting the transmitter to adjust the position of the first light spot and the position of the second light spot until the photoelectric conversion module is positioned between the first light spot and the second light spot. For more information on adjusting the transmitter, please refer to the preceding text.

[0138] In some embodiments, the charging beam emitting unit is disposed between the first group of visible beam emitting subunits and the second group of visible beam emitting subunits, such that when the photoelectric conversion module is located between the first light spot and the second light spot, the charging beam emitted by the charging beam emitting unit is aligned with a preset position. As shown in FIG6, since the charging beam emitting unit is disposed between the first group of visible beam emitting subunits and the second group of visible beam emitting subunits, and the relative positions of the charging beam emitting unit with the first group of visible beam emitting subunits and the second group of visible beam emitting subunits are fixed, when the preset position is located between the first light spot and the second light spot, it indicates that the charging beam emitted by the charging beam emitting unit is aligned with the preset position; such as the infrared light irradiation area shown in FIG6.

[0139] In some embodiments, the charging beam emitting unit includes two sets of charging beam emitting subunits. Each set of charging beam emitting subunits includes two charging beam emitters. The visible beam emitting unit includes two sets of visible beam emitting subunits. Each set of visible beam emitting subunits includes two visible beam emitters.

[0140] In some embodiments, as shown in FIG4, a visible beam emitter and a charging beam emitter are installed side by side. The visible beam emitter can be installed inside the charging beam emitter. Since the focal point of the collimating lens corresponds to the charging beam emitter, when the charging beam emitter and the visible beam emitter are installed side by side and the emitting end and the receiving end are aligned, the light spot formed by the light emitted by the charging beam emitter is on the receiving end (or photocell), while the light spot formed by the visible beam emitter will deviate from the photocell. The visible beam will illuminate an area outside the receiving end. For example, if the receiving end is set on a door, the visible light will illuminate an area outside a preset position on the door, such as an area outside the photoelectric conversion module on the door.

[0141] As shown in Figure 5, taking the charging beam emitter as an example of an infrared light emitter, the infrared light emitter and the visible light beam emitter are arranged side by side, with the infrared light emitter corresponding to the focal point of the collimating lens. For instance, the light-emitting area of ​​the semiconductor chip inside the infrared light emitter is placed at the geometric focal point of the collimating lens. When the transmitting and receiving ends are aligned, the visible light spot of the visible beam is outside the infrared light illumination area. As shown in Figure 4, each visible beam emitter forms one visible light spot, and there are two visible light spots for each visible beam, with the spots positioned on either side of the infrared light illumination area, as shown in Figure 6.

[0142] To ensure that the charging beam accurately illuminates the photoelectric conversion module after alignment, the charging beam emitting unit can be positioned between the first set of visible beam emitting subunits and the second set of visible beam emitting subunits. When the photoelectric conversion module is located in the center of the visible light spot, the charging beam can be precisely aligned with the photoelectric conversion module.

[0143] Figure 7 is a schematic diagram of a visible light beam emitting unit arranged around a collimating lens according to some embodiments of this specification; Figure 8 is a schematic diagram of the position of the light spot when a visible light beam emitting unit is arranged around a collimating lens according to some embodiments of this specification.

[0144] In some embodiments, the visible beam emitting unit includes a plurality of visible beam emitters arranged around the charging beam emitting unit (as shown in FIG. 7), and the visible beam spot includes a plurality of sub-spots, which are formed by the plurality of visible beam emitters. In some embodiments, adjusting the emitting end until the position of the visible beam spot is at a preset position includes: adjusting the emitting end to adjust the positions of the plurality of sub-spots until the preset position is at the center of the plurality of spot positions. The center of the plurality of spot positions may refer to the approximate geometric center of the plurality of spot positions. For example, when the plurality of sub-spots form a ring that surrounds the photoelectric conversion module in the center of the plurality of sub-spots, the preset position being at the center of the plurality of spot positions indicates that the charging beam is aligned.

[0145] For example, visible beam emitters can be positioned around the collimating lens, and the number of visible beam emitters can be set as needed. As shown in Figure 7, taking the visible beam emitter as a laser emitter as an example, four laser emitters are positioned around the collimating lens, each corresponding to a visible light spot. The power of the laser emitters can be set to a low power, such as 10% or 20% of the rated power, to ensure that it will not cause harm to the human body.

[0146] After multiple visible light emitters illuminate the receiver, multiple visible light spots are formed. By adjusting the illumination angle of the emitter and aligning the emitter and receiver, multiple visible light spots can be positioned around the photovoltaic cell, as shown in Figure 8.

[0147] Figure 9 is a schematic diagram of a visible beam emitting unit set at the geometric center of a plurality of collimating lenses according to some embodiments of this specification; Figure 10 is a schematic diagram of a visible beam emitting unit set at the geometric center of a plurality of collimating lenses according to some embodiments of this specification; Figure 11 is a schematic diagram of the beam spot position when a visible beam emitting unit is set at the geometric center of a plurality of collimating lenses according to some embodiments of this specification.

[0148] In some embodiments, adjusting the transmitter until the position of the visible light spot is at a preset position includes: adjusting the transmitter to adjust the position of the visible light spot until the position of the visible light spot is at the center of the photoelectric conversion module.

[0149] In some embodiments, the visible beam emitting unit is located at the center of the charging beam emitting unit.

[0150] For example, as shown in Figures 9 and 10, the transmitter includes multiple collimating lenses and multiple charging beam emitters. A visible beam emitter is installed at the geometric center of the transmitter, and charging beam emitters are arranged around the visible beam emitter. By adjusting the illumination angle of the transmitter, when the transmitter and receiver are aligned, the visible light spot emitted by the visible beam emitting unit is located at the center point of the photovoltaic cell, as shown in Figure 11.

[0151] In some embodiments, the transmitter is provided with a charging beam emitter, and the visible beam emitter can be located at the center of the charging beam emitter or at the center of the collimating lens. After the transmitter and receiver are aligned, the visible light spot of the visible beam emitter is located at the center of the photoelectric conversion module.

[0152] When the visible light spot is located at the center of the photoelectric conversion module, the visible light spot can directly indicate the center alignment point of the charging beam, making it convenient for users to determine whether it is aligned.

[0153] It should be noted that the above configuration of the visible beam emitting unit and the charging beam emitting unit is only an example. In actual use, the number of charging beam emitters, the number of visible beam emitters, and the location of the visible beam emitters can be selected as needed. This manual does not impose any restrictions.

[0154] In some embodiments of this specification, a visible beam emitting unit is provided on the transmitting end, and charging alignment is performed according to the position of the visible beam spot. The alignment method is simple and efficient.

[0155] Some embodiments of this specification also provide a control method for a wireless charging device. The wireless charging device includes a receiver and a transmitter. The transmitter includes a visible light beam emitting unit and a charging light beam emitting unit; the receiver includes a photovoltaic cell. The control method includes: controlling the visible light beam emitting unit of the transmitter to emit a visible light beam, which forms a visible light spot after illuminating the area where the receiver is located; adjusting the transmitter until the position of the visible light spot is at a preset position, the preset position being used to characterize the area where the photovoltaic cell is located.

[0156] In some embodiments, the visible beam emitting unit includes two sets of visible beam emitting subunits, and the visible light spot includes a first light spot and a second light spot; the visible beam emitted by the first set of visible beam emitting subunits forms the first light spot; the visible beam emitted by the second set of visible beam emitting subunits forms the second light spot.

[0157] In some embodiments, adjusting the emitting end until the position of the visible light spot is at a preset position includes: adjusting the emitting end to adjust the position of the first light spot and the position of the second light spot until the photovoltaic cell is between the first light spot and the second light spot.

[0158] In some embodiments, the visible beam emitting unit includes a plurality of visible beam emitters arranged around the charging beam emitting unit, and the visible light spot includes a plurality of sub-spots, with the plurality of visible beam emitters correspondingly forming the plurality of sub-spots. Adjusting the emitting end until the position of the visible light spot is at a preset position includes: adjusting the emitting end to adjust the position of the plurality of sub-spots until the position of the plurality of sub-spots is around the photovoltaic cell.

[0159] In some embodiments, adjusting the transmitter until the position of the visible light spot is at a preset position includes: adjusting the transmitter to adjust the position of the visible light spot until the position of the visible light spot is at the center of the photovoltaic cell.

[0160] In some embodiments, after adjusting the emitting end until the position of the visible light spot is at a preset position, the method further includes: controlling the visible light beam emitting unit to turn off; and controlling the charging light beam emitting unit to emit a light beam at a preset power to charge the photovoltaic cell.

[0161] For more information on charging photovoltaic cells, similar to that on powering the receiver and / or charging energy storage devices electrically connected to the receiver, see the preceding text.

[0162] During the recharging process of wireless charging devices (such as smart door locks), other anomalies may occur that prevent the receiver from charging. In this case, if the charging beam emitting unit continues to emit a charging beam, it will lead to unnecessary energy waste.

[0163] Figure 12 is a schematic diagram of a wireless charging device according to some embodiments of this specification. As shown in Figure 12, the wireless charging device 1200 includes a transmitter 1210 and a receiver 1220. The transmitter 1210 includes a charging beam emitting unit (e.g., a light source 1211), and the receiver 1220 includes a photoelectric conversion module 1221. For more information on the charging beam emitting unit, the receiver, and the photoelectric conversion module, please refer to other parts of this specification, such as Figures 1-10 and their related descriptions.

[0164] Figure 13 is an exemplary flowchart of a control method according to some embodiments of this specification. As shown in Figure 13, process 1300 includes steps 1310 to 1330. In some embodiments, process 1300 may be executed by a processor.

[0165] Step 1310: In response to the wireless charging device meeting the charging protection conditions, a second control command is generated to control the charging beam emitting unit to stop emitting the charging beam.

[0166] Charging protection conditions refer to preset trigger conditions for stopping or limiting charging. For example, a charging protection condition can be a single condition. For instance, a charging protection condition could be any one of the following: currently outside the charging period, a human body detected within the beam radiation area, the remaining battery power of the receiver exceeding a battery threshold, or the door lock being in the open state.

[0167] When the wireless charging device is in a charging state, the receiver determines whether the wireless charging device meets the charging protection conditions, and in response to the wireless charging device meeting the charging protection conditions, generates a second stop charging command and sends it to the charging beam emitting unit to control the charging beam emitting unit to stop emitting the charging beam.

[0168] In some embodiments, the charging protection conditions include multiple conditions, such as being outside the charging period at the current time, a human body being detected within the beam radiation area, the remaining power of the receiver being greater than a power threshold, and the door lock being in the open state. The receiver (or processor) determines whether the wireless charging device meets all the charging protection conditions, and in response to the wireless charging device meeting all the charging protection conditions in the charging state, generates a second stop charging command.

[0169] If the charging protection condition includes the current time being outside the charging period, the charging period can be preset by the user. For example, the receiving end includes a setting module, and the user sets the charging period based on the setting module, or the user sets the charging period based on the smart terminal and sends it to the receiving end. Alternatively, the charging period can be determined based on historical charging time. For example, the receiving end determines the charging period based on stored historical charging time, or the smart terminal determines the charging period based on stored historical charging time and sends the charging period to the receiving end.

[0170] If the charging protection condition includes that the remaining power of the receiver is greater than the power threshold, and the power threshold can be any value between 90% and 100%, then when the remaining power of the receiver is greater than the power threshold, the remaining power of the receiver is large, and the receiver does not need to be charged.

[0171] If the charging protection condition includes the detection of a human body within the beam radiation area, the charging beam emitting unit or receiving end includes a first sensor. The processor can determine whether a human body is detected within the beam radiation area based on the information collected by the first sensor. When a human body is detected within the beam radiation area, the risk of harm to the human body is relatively high.

[0172] For example, the first sensor can be a time-of-flight (TOF) sensor, radar sensor, or ultrasonic sensor, which can acquire the distance between the human body and the sensor. When the distance between the human body and the sensor is less than the distance between the edge of the beam's radiation area and the sensor, it is determined that a human body has been detected within the beam's radiation area. Alternatively, the first sensor can be an image sensor, which can acquire an image within the beam's radiation area; when the acquired image includes a human body, it is determined that a human body has been detected within the beam's radiation area. Or, the first sensor can be a polar infrared (PIR) sensor, which can acquire thermal radiation signals within the beam's radiation area; when thermal radiation signals are acquired, it is determined that a human body has been detected within the beam's radiation area.

[0173] If the charging protection conditions include the door lock being in the open state, the receiver cannot receive the charging beam when the door lock is in the open state, and the wireless charging device cannot charge.

[0174] In some embodiments, a wireless charging device is installed on the smart lock. The wireless charging device or the lock itself contains a second sensor (such as a Hall sensor, limit switch, micro switch, etc.), configured to detect the opening or closing state of the lock bolt or the door itself, thereby determining whether the lock is in the open state.

[0175] For example, the charging beam emitting unit includes a power supply module. When the wireless charging device is charging, the power supply module continuously supplies power to the charging beam emitting unit. In response to a second stop charging command, the processor generates a power-off control signal; in response to the power-off control signal, the wireless charging device disconnects the connection between the power supply module and the charging beam emitting unit, causing the charging beam emitting unit to stop emitting the charging beam, and the wireless charging device enters a charging stop state.

[0176] In other embodiments, the processor can send a second stop charging command to the charging beam emitting unit. The control unit in the charging beam emitting unit responds to the second stop charging command by generating a power adjustment signal and controlling the driving module to drive the charging beam emitting unit to emit a charging beam at zero power according to the power adjustment signal, so that the charging beam emitting unit stops emitting the charging beam and the wireless charging device enters a charging stop state.

[0177] Step 1320: In response to the wireless charging device meeting the conditions for resuming charging, a second control command is generated to control the charging beam emitting unit to emit a charging beam at a first power.

[0178] For example, the recharge recovery condition can be one of the following: the current time is within a charging period, no human body is detected within the beam radiation area, the door lock is closed, and the remaining battery power of the receiver is less than a preset battery power. The receiver determines whether the wireless charging device in the stopped charging state meets the recharge recovery condition, and in response to the wireless charging device meeting the recharge recovery condition, generates a pre-charge command and sends the pre-charge command to the charging beam transmitting unit to control the charging beam transmitting unit to emit a charging beam at a first power.

[0179] In some embodiments, the charging resumption conditions include multiple conditions, such as being currently within a charging period, no human body detected within the beam radiation area, the door lock being closed, and the remaining battery power of the receiver being less than a preset amount. The receiver determines whether the wireless charging device in the stopped charging state meets all the charging resumption conditions, and in response to the wireless charging device meeting all the charging resumption conditions, generates a pre-charging command.

[0180] If the conditions for resuming charging include being in a charging period at the current time and not having a human body detected within the beam radiation area, the receiver generates a pre-charging command when the wireless charging device is in a charging period at the current time and no human body is detected within the beam radiation area.

[0181] If the conditions for resuming charging include being in a charging period at the current time, no human body being detected within the beam radiation area, and the door lock being closed, the receiver generates a pre-charging command when the wireless charging device is in a charging period at the current time, no human body is detected within the beam radiation area, and the door lock is closed.

[0182] If the conditions for resuming charging include being in a charging period at the current time, no human body being detected within the beam radiation area, the door lock being closed, and the remaining power of the receiver being less than the preset power, the receiver generates a pre-charging command when the wireless charging device is currently in a charging period, no human body is detected within the beam radiation area, the door lock is closed, and the remaining power of the receiver is less than the preset power.

[0183] When the charging beam emitting unit receives the pre-charging command sent by the receiver, the control unit responds to the pre-charging command, generates a first control signal, and controls the drive module to adjust the power of the charging beam emitting unit to a first power according to the first control signal, so that the charging beam emitting unit emits a charging beam at a lower first power, and the wireless charging device enters the pre-charging state.

[0184] In some embodiments, steps 1311 and 1312 may be included before step 1320.

[0185] Step 1311: Determine the charging period based on the user's historical daily routine and travel time.

[0186] For example, the receiver can determine a user's daily routine based on indoor sound signals and / or indoor image information, and record the user's historical daily routine; it can also determine a user's travel time based on door lock opening and closing times and / or outdoor image information, and record the user's historical travel time. The receiver (or processor) can determine historical daily routines and historical travel times in various ways, such as through data statistics, machine learning models, etc.

[0187] The receiving end (or its associated smart terminal) can collect indoor sound signals, indoor image information and outdoor image information through internal or external sensors (such as indoor sound signal sensors or image acquisition devices on door locks).

[0188] The receiving end determines the charging period based on the user's historical daily routine and travel time, or it can determine a portion of the time period corresponding to the historical daily routine and travel time as the charging period.

[0189] For example, if a user's historical daily routine is 23:00-07:00 and their historical travel time is 08:30-18:00, then the charging periods can be determined to be 23:00-07:00 and 08:30-18:00, or the charging periods can be determined to be 01:00-05:00, 9:00-12:00 and 14:00-18:00.

[0190] Step 1312: Adjust the charging period based on user habits and user settings. User settings include whether to set up hourly workers and / or whether to set up a delivery service mode.

[0191] The processor can determine user habits in various ways. For example, it can confirm user habits based on user settings and through statistical methods. Alternatively, users can set their habits through their smart devices. User habits refer to those that may affect the charging times of wireless charging devices. For example, user habits include times when visitors arrive, hours when hourly workers are available, and times when delivery services are available. The processor can eliminate user habits that might affect the charging times of the wireless charging device, thereby preventing the charging beam from radiating onto the human body.

[0192] In some embodiments, user settings include whether a part-time worker is set. If the user settings indicate that a part-time worker is set, and the user's habits include the user-set part-time worker time slots, then the time slots that overlap with the part-time worker time slots in the charging time slots are removed to obtain the final charging time slots; if the user settings indicate that a part-time worker is not set, then the charging time slots are not adjusted.

[0193] For example, if the charging period is 08:30-18:00 and the hourly worker's period is 08:30-11:00, and the user has set up an hourly worker, the final charging period will be 11:00-18:00. If the user has not set up an hourly worker, the final charging period will still be 08:30-18:00.

[0194] In some embodiments, user settings include whether a delivery service mode is set. If the user settings indicate that a delivery service mode is set, and the user's habits include the user-set delivery service time period, then the time periods that overlap with the delivery service time period in the charging time period are removed to obtain the final charging time period. If the user settings indicate that a delivery service mode is not set, then the charging time period is not adjusted.

[0195] For example, if the charging period is 08:30-18:00 and the express delivery service period is 13:00-15:00, and the user has set the express delivery service mode, then the final charging period will be 08:30-13:00 and 15:00-18:00. If the user has not set the express delivery service mode, then the final charging period will still be 08:30-18:00.

[0196] In other embodiments, the user settings include whether to set hourly worker and courier service modes. If the user settings indicate that hourly worker and courier service modes are set, and the user's habits include the hourly worker and courier service time periods set by the user, then the charging time periods that overlap with the courier service and hourly worker time periods are removed to obtain the final charging time period.

[0197] If the user's settings indicate that they have set up a part-time worker but not a courier service mode, then the charging time slots that overlap with the part-time worker's time slots will be removed to obtain the final charging time slots. If the user's settings indicate that they have set up a courier service mode but not a part-time worker, then the charging time slots that overlap with the courier service's time slots will be removed to obtain the final charging time slots. If the user's settings indicate that they have not set up either a part-time worker or a courier service mode, then the charging time slots will not be adjusted.

[0198] For example, the charging period is 08:30-18:00, the hourly service period is 08:30-11:00, and the courier service period is 13:00-15:00. If the user's settings indicate that an hourly service is enabled but a courier service is not enabled, the final charging period will be 11:00-18:00. If the user's settings indicate that a courier service is enabled but an hourly service is not enabled, the final charging period will be 08:30-13:00 and 15:00-18:00. If the user's settings indicate that both an hourly service and a courier service are enabled, the final charging period will be 11:00-13:00 and 15:00-18:00. If the user's settings indicate that neither an hourly service nor a courier service is enabled, the final charging period will still be 08:30-18:00.

[0199] Step 1330: In response to the wireless charging device meeting normal charging conditions, a second control command is generated to control the charging beam emitting unit to emit a charging beam at a second power, the second power being greater than the first power.

[0200] For example, normal charging conditions include being within the charging period at the current moment, no human body being detected within the beam radiation area, the door lock being closed, and the remaining power of the receiver being less than a preset power level. The receiver determines whether the wireless charging device in the pre-charging state meets all the conditions for normal charging, and in response to the wireless charging device meeting all the conditions for normal charging, generates a first charging command and sends the first charging command to the charging beam emitting unit to control the charging beam emitting unit to emit a charging beam at a second power greater than the first power.

[0201] When the charging beam emitting unit receives the first charging command sent by the receiver, the control unit responds to the first charging command, generates a second control signal, and controls the drive module to increase the power of the charging beam emitting unit from the first power to the second power according to the second control signal, so that the charging beam emitting unit emits the charging beam at a larger second power, and the wireless charging device enters the charging state.

[0202] Thus, during the recharging process, the charging beam emitting unit first emits a charging beam at a low power, allowing the wireless charging device to pre-charge based on the low-power beam. Once the wireless charging device meets the normal charging conditions, the charging beam emitting unit then emits a charging beam at a high power, allowing the wireless charging device to charge normally based on the high-power beam.

[0203] In some embodiments of this specification, by controlling the charging beam emitting unit to stop emitting the charging beam in response to the wireless charging device meeting the charging protection condition, controlling the charging beam emitting unit to emit the charging beam at a first power in response to the wireless charging device meeting the resumption charging condition, and controlling the charging beam emitting unit to emit the charging beam at a second power greater than the first power in response to the wireless charging device meeting the normal charging condition, it is possible to charge with a low-power beam first during the resumption charging process, and then charge with a high-power beam when the wireless charging device meets the normal charging condition, which can reduce energy waste.

[0204] In some embodiments, step 1321 is included before performing step 1330.

[0205] Step 1321: Determine whether the wireless charging device meets the normal charging conditions based on whether a photoelectric conversion signal is detected at the receiving end.

[0206] For example, the photoelectric conversion signal can be an electrical signal, specifically voltage, current, or power. For instance, if the photoelectric conversion signal is voltage, the receiving end can continuously monitor the output voltage of the photoelectric conversion module. When the output voltage of the photoelectric conversion module is less than the background noise voltage, it is determined that the receiving end has not detected a photoelectric conversion signal; when the output voltage of the photoelectric conversion module is greater than the background noise voltage, it is determined that the receiving end has detected a photoelectric conversion signal.

[0207] For example, if the photoelectric conversion signal is current, the receiving end can continuously monitor the output current of the photoelectric conversion module. When the output current of the photoelectric conversion module is less than the background noise current, it is determined that the receiving end has not detected a photoelectric conversion signal; when the output current of the photoelectric conversion module is greater than the background noise current, it is determined that the receiving end has detected a photoelectric conversion signal. Similarly, if the photoelectric conversion signal is power, the receiving end can continuously monitor the output power of the photoelectric conversion module. When the output power of the photoelectric conversion module is less than the background noise power, it is determined that the receiving end has not detected a photoelectric conversion signal; when the output power of the photoelectric conversion module is greater than the background noise power, it is determined that the receiving end has detected a photoelectric conversion signal.

[0208] In some embodiments, normal charging conditions also include detecting a photoelectric conversion signal at the receiving end. When the wireless charging device is in a pre-charging state, provided that the wireless charging device is currently within the charging period, no human body is detected within the beam radiation area, the door lock is closed, and the remaining power at the receiving end is less than a preset power, if a photoelectric conversion signal is detected at the receiving end, it can be determined that the wireless charging device meets the normal charging conditions.

[0209] If no photoelectric conversion signal is detected at the receiver when the wireless charging device is in the pre-charging state, provided that the wireless charging device is currently within the charging period, no human body is detected within the beam radiation area, the door lock is closed, and the remaining power of the receiver is less than the preset power, it can be determined that the wireless charging device does not meet the normal charging conditions.

[0210] In some embodiments of this specification, by controlling the charging beam emitting unit to stop emitting the charging beam in response to the wireless charging device meeting the charging protection condition, controlling the charging beam emitting unit to emit the charging beam at a first power in response to the wireless charging device meeting the resumption charging condition, and controlling the charging beam emitting unit to emit the charging beam at a second power greater than the first power in response to the wireless charging device meeting the normal charging condition, it is possible to charge with a low-power beam first during the resumption charging process, and then charge with a high-power beam when the wireless charging device meets the normal charging condition, which can reduce energy waste.

[0211] Typically, the infrared laser emitted by the charging beam emitting unit is invisible and cannot be perceived by the human eye. Looking directly at the laser source can cause eye damage; therefore, if the laser poses a risk of harm during charging, the laser source must be switched off to prevent injury. However, frequently switching the laser source on and off can damage it, affecting its lifespan and consequently the lifespan of the wireless charging device.

[0212] Figure 14 is a schematic diagram of the wireless charging device in a stopped charging state according to some embodiments of this specification. As shown in Figure 14, the wireless charging device includes a transmitter 1410 and a receiver 1420. The transmitter 1410 includes a charging beam emitting unit 1411 and a blocking member 1412. The receiver 1420 includes a photoelectric conversion module 1421. For more information on the charging beam emitting unit, the receiver, and the photoelectric conversion module, please refer to other parts of this specification, such as Figures 1-10 and their related descriptions.

[0213] A blocking element is used to block the charging beam emitted by the charging beam emitting unit 1411. The blocking element can be disposed between the emitting end 1410 and the receiving end 1420. For example, it can be disposed in the transmission path of the charging beam. The structure of the blocking element is not limited here; for example, the blocking element can be a sliding blocking plate, a rotating blocking plate, or a flip-top blocking plate, etc. The wireless charging device is also provided with a motor, which is configured to drive the blocking element to block the charging beam emitting unit.

[0214] In some embodiments, there can be multiple blocking elements. For example, when the multiple charging beam emitting units are arranged as shown in Figure 4, two sets of blocking elements can be provided, with each set of blocking elements corresponding to one of the two sets of charging beam emitting subunits.

[0215] In some embodiments, the second control command further includes instructions to control a blocking element. For example, the second control command includes controlling one or more blocking elements to block the charging beam emitting unit via the transmitter.

[0216] For example, when the receiving module receives a first stop charging command sent by the receiving end 1420, the processor responds to the first stop charging command by controlling the blocking member 1412 to block the charging beam emitting unit 1411, so as to prevent the charging beam emitted by the charging beam emitting unit 1411 from shining on the receiving end 1420, thereby causing the wireless charging device to enter a stop charging state, as shown in FIG14. The stop charging state refers to the state in which the wireless charging device is not charging. For example, when the connection between the power supply module and the charging beam emitting unit is disconnected, or when the power of the charging beam emitting unit is reduced to a preset power (such as zero power), the wireless charging device is in a stop charging state. As another example, when the blocking member blocks the charging beam emitting unit, the wireless charging device is in a stop charging state.

[0217] Figure 15 is a schematic diagram of the wireless charging device in a charging state according to some embodiments of this specification. When the wireless charging device is in a stopped charging state, if the receiving module receives a second charging command sent by the receiving end 1420, the processor responds to the second charging command by controlling the blocking member 1412 not to block the charging beam emitting unit 1411, so that the charging beam emitted by the charging beam emitting unit 1411 illuminates the receiving end 1420, as shown in Figure 15.

[0218] Figure 16 is a flowchart illustrating a control method according to some embodiments of this specification. As shown in Figure 16, process 1600 includes steps 1610 to 1620. In some embodiments, process 1600 may be executed by a processor.

[0219] Step 1610: When the wireless charging device meets a preset interruption condition, a first stop charging command is generated by the receiver. The preset interruption condition includes a stop charging condition and / or the wireless charging device being in a standby state. A standby state refers to a low-power operating mode during which the wireless charging device (e.g., the transmitter) is inactive. In standby mode, the wireless charging device has stopped or suspended its core functions (e.g., stopped transmitting the charging beam), but remains powered on and ready to respond to other events. These other events include commands from the user or the receiver (e.g., a second control command, a first control command, etc.).

[0220] For example, the charging stop condition can be any one of the following: the current time is outside the charging period, a human body is detected within the beam radiation area, the remaining power of the receiver is greater than a preset power level, or the receiver does not detect a photoelectric conversion signal. When the wireless charging device in the charging state meets the charging stop condition, the receiver generates a first charging stop command and sends the first charging stop command to the transmitter. For more information on the charging period, the detection of a human body within the beam radiation area, the preset power level, and the photoelectric conversion signal, please refer to other parts of this specification, such as Figures 12-13 and their related descriptions.

[0221] In some embodiments, the charging stop condition includes multiple conditions. For example, the charging stop condition includes multiple conditions such as being outside the charging period at the current time, a human body being detected within the beam radiation area, the remaining power of the receiver being greater than a preset power, and the receiver not detecting a photoelectric conversion signal. When the wireless charging device in the charging state meets all the charging stop conditions, the receiver generates a first charging stop command.

[0222] If the charging stop condition includes the current time being outside the preset charging period, the preset charging period can be a charging period preset by the user, or the preset charging period can be a charging period determined based on historical charging time.

[0223] If the charging stop condition includes the remaining power of the receiver being greater than the preset power, and the preset power can be any value between 90% and 100%, then the receiver does not need to be charged when the remaining power of the receiver is greater than the preset power.

[0224] If the charging stop condition includes the detection of a human body within the beam radiation area, the transmitter or receiver includes a first sensor. Based on the information collected by the first sensor, it can be determined whether a human body is detected within the beam radiation area. When a human body is detected within the beam radiation area, the risk of injury to that person is high. For more information about the first sensor, please refer to other parts of this specification, such as Figures 12-13 and their related descriptions.

[0225] Charging may stop if the receiver does not detect a photoelectric conversion signal, or if the door lock is in the open state or there is a problem with the alignment between the transmitter and receiver.

[0226] When a wireless charging device enters standby mode while charging, the receiver will generate a first stop charging command and send it to the transmitter.

[0227] If the wireless charging device is in standby mode and the conditions for stopping charging are met, such as when the wireless charging device has been inactive for a long time and a human body is suddenly detected in the beam radiation area, the receiver generates a first stop charging command to prevent the wireless charging device from starting charging immediately after being released from standby mode, which could cause danger.

[0228] Step 1620: In response to receiving the first stop charging command, the transmitter controls the blocking device to block the charging beam emitting unit to prevent the charging beam from shining on the photoelectric conversion module.

[0229] For example, the transmitter includes a control unit and a motor. The motor is configured to move or rotate the blocking element. When the wireless charging device is charging, if the transmitter receives a first stop charging command generated by the receiver, the control unit responds to the first stop charging command by generating a fifth control signal and drives the motor to rotate in a first clockwise direction according to the fifth control signal. For example, the first clockwise direction can be clockwise or counterclockwise.

[0230] The motor is connected to the shielding component. The rotation of the motor in the first clockwise direction can drive the shielding component to move between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, thereby preventing the charging beam from shining on the receiving end, so that the wireless charging device enters the stopped charging state, as shown in Figure 14.

[0231] When the wireless charging device in the stopped charging state meets the preset charging conditions, the receiver generates a second charging command and sends the second charging command to the transmitter. In response to the second charging command, the transmitter controls the blocking member not to block the charging beam emitting unit so that the charging beam can illuminate the receiver.

[0232] For example, the preset charging condition can be one. For instance, the preset charging condition is that the current time is within the charging period, no human body is detected within the beam radiation area, the remaining power of the receiver is less than the preset charging power, and the receiver detects a photoelectric conversion signal, wherein the preset charging power is less than the preset power.

[0233] In some embodiments, the preset charging conditions include multiple conditions. For example, the preset charging conditions include being in a charging period at the current moment, no human body being detected within the beam radiation area, the remaining power of the receiver being less than a preset charging amount, and the receiver detecting a photoelectric conversion signal. When the wireless charging device in the stopped charging state meets all the preset charging conditions, the receiver generates a second charging command.

[0234] If the preset charging conditions include being in a charging period and no human body being detected within the beam's radiation area, the receiver generates a second charging command when the wireless charging device is in a charging period and no human body is detected within the beam's radiation area.

[0235] If the preset charging conditions include being in a charging period at the current time, no human body being detected within the beam radiation area, and the remaining power of the receiver being less than the preset charging power, then when the wireless charging device is in a charging period at the current time, no human body is detected within the beam radiation area, and the remaining power of the receiver is less than the preset charging power, the receiver generates a second charging command.

[0236] If the preset charging conditions include being in a charging period at the current time, no human body being detected within the beam radiation area, the remaining power of the receiver being less than the preset charging power, and the receiver detecting a photoelectric conversion signal, then the receiver generates a second charging command when the wireless charging device is currently in a charging period, no human body is detected within the beam radiation area, the remaining power of the receiver is less than the preset charging power, and the receiver detects a photoelectric conversion signal.

[0237] The control unit of the transmitter responds to the second charging command, generates a fourth control signal, and drives the motor to rotate in the second clockwise direction according to the fourth control signal, so as to remove the blocking member from the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiver, thereby ensuring that the charging beam shines on the receiver so that the wireless charging device enters the charging state, as shown in Figure 15.

[0238] The second clockwise direction is the opposite of the first clockwise direction. For example, if the first clockwise direction is clockwise, then the second clockwise direction is counterclockwise, and if the first clockwise direction is counterclockwise, then the second clockwise direction is clockwise.

[0239] In some embodiments of this specification, when the wireless charging device meets a preset interruption condition, the blocking component is controlled to block the charging beam emitting unit (e.g., block the charging beam) to prevent the charging beam emitted by the charging beam emitting unit from shining on the receiving end. This can block the charging beam in standby and charging-stop states without turning off the charging beam emitting unit, thereby reducing the switching frequency of the charging beam emitting unit and extending its service life.

[0240] In some embodiments, the plane containing the shielding member is perpendicular to the optical axis of the charging beam. The shielding member can rotate in the plane perpendicular to the optical axis. For example, the shielding member can rotate clockwise in the plane perpendicular to the optical axis, and it can also rotate counterclockwise in the plane perpendicular to the optical axis.

[0241] In some embodiments, the control unit of the transmitter may, in response to a first stop charging command, control the blocking member to rotate or translate between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the photoelectric conversion module.

[0242] For example, in response to the first stop charging command, the control unit generates a fifth control signal and drives the motor to rotate in a first clockwise direction according to the fifth control signal. The rotation of the motor in the first clockwise direction can drive the blocking member to rotate in a third clockwise direction in a plane perpendicular to the optical axis to the space between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, as shown in Figure 14. For example, the third clockwise direction can be clockwise or counterclockwise.

[0243] The control unit responds to the second charging command, generates a fourth control signal, and drives the motor to rotate in the second clockwise direction according to the fourth control signal. The rotation of the motor in the second clockwise direction can drive the blocking member to rotate and move out from between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end in the fourth clockwise direction in a plane perpendicular to the optical axis, as shown in Figure 15.

[0244] The fourth clockwise direction is the opposite of the third clockwise direction. For example, if the third clockwise direction is clockwise, then the fourth clockwise direction is counterclockwise, and vice versa.

[0245] In some embodiments, the rotation of the motor in the first clockwise direction can cause the blocking member to translate in a plane perpendicular to the optical axis to between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, as shown in Figure 14. The rotation of the motor in the second clockwise direction can cause the blocking member to translate out from between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end in a plane perpendicular to the optical axis, as shown in Figure 15.

[0246] It should be noted that Figures 14 and 15 only exemplarily show that the shield 1412 is located outside the charging beam emitting unit 1411. In actual applications, the shield 1412 can also be located inside the charging beam emitting unit 1411. This specification does not impose any specific limitations on this.

[0247] In some embodiments, the control unit may, in response to a first stop charging command, control two blocking members to move toward each other between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the photoelectric conversion module.

[0248] For example, the transmitting end includes two blocking members, which can move towards each other in a plane perpendicular to the optical axis, and can also move away from each other in a plane perpendicular to the optical axis. Rotation of the motor in a first clockwise direction controls the two blocking members to move towards each other in a plane perpendicular to the optical axis until they are between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end. Rotation of the motor in a second clockwise direction causes the two blocking members to move away from each other in a plane perpendicular to the optical axis.

[0249] In some embodiments, the plane of the shielding member is perpendicular to the optical axis of the charging beam, the shielding member is fixed between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, and the transmittance of the shielding member is adjustable.

[0250] In some embodiments, the control unit may, in response to a first stop charging command, reduce the transmittance of the obstruction located between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the photoelectric conversion module. Transmittance refers to the degree to which the obstruction allows the charging beam to pass through. Transmittance can be measured using a value between 0 and 100%. 0 indicates complete opacity, meaning the charging beam is completely blocked. 100% indicates complete transparency (i.e., no obstruction).

[0251] For example, in response to a first stop charging command, the control unit reduces the transmittance of the blocking element to reduce the light intensity received by the receiver, and in response to a second charging command, the control unit increases the transmittance of the blocking element to increase the light intensity received by the receiver.

[0252] Figure 17 is a flowchart illustrating another control method according to some embodiments of this specification. As shown in Figure 17, process 1700 includes the following steps.

[0253] Step 1710: When the wireless charging device meets the preset interruption condition, a first stop charging command is generated by the receiver. Step 1720: In response to the transmitter receiving the first stop charging command, the transmitter controls the blocking device to block the charging beam emitting unit. The contents of steps 1710 and 1720 are similar to those of steps 1610 and 1620, as described in Figure 16.

[0254] Step 1730: When the photoelectric conversion module receives the charging beam, or when the duration of the wireless charging device meeting the conditions for stopping charging exceeds a preset duration, a first stop charging command is generated through the receiver.

[0255] For example, when the wireless charging device meets the preset interruption condition, if the receiver still receives the charging beam emitted by the charging beam emitting unit and the blocking component fails to completely block the charging beam emitted by the charging beam emitting unit, then the blocking component is abnormal, that is, there is still a certain safety hazard. At this time, the receiver generates a first stop charging command.

[0256] Step 1740: In response to receiving the first stop charging command, the transmitter controls the charging beam emitting unit to shut down.

[0257] Figure 18 is a schematic diagram of the wireless charging device in a closed state according to some embodiments of this specification. Exemplarily, in response to a first stop charging command, the transmitter generates a shutdown control signal, and controls the charging beam transmitting unit to shut down according to the shutdown control signal, thereby causing the wireless charging device to enter a closed state, as shown in Figure 18.

[0258] When the wireless charging device is in the off state, the charging beam emitting unit is off and the blocking component prevents the charging beam from shining on the receiving end. The control unit, in response to the second charging command, generates a fourth control signal and a fifth control signal. Based on the fifth control signal, it controls the charging beam emitting unit to turn on, causing it to emit a charging beam. Based on the fourth control signal, it drives the motor to prevent the blocking component from blocking the charging beam emitting unit, allowing the charging beam to shine on the receiving end, thus putting the wireless charging device into charging mode.

[0259] When the charging beam emitting unit is turned on and the blocking member is located between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, the control unit can respond to the second charging command, generate a fourth control signal, and drive the motor according to the fourth control signal to control the blocking member not to block the charging beam emitting unit, so that the charging beam shines on the receiving end, and the wireless charging device enters the charging state.

[0260] In some embodiments of this specification, when the obstruction is abnormal, the receiver generates a first stop charging command, and the transmitter responds to the first stop charging command by shutting down the charging beam emitting unit, which can improve the safety of the wireless charging device.

[0261] Figure 19 is a flowchart illustrating another control method according to some embodiments of this specification. As shown in Figure 19, process 1900 includes the following steps 1910 to 1940.

[0262] Step 1910: When the wireless charging device meets the preset interruption condition, a first stop charging command is generated by the receiver. Step 1920: In response to the transmitter receiving the first stop charging command, the transmitter controls the blocking device to block the charging beam emitting unit, thereby preventing the charging beam from illuminating the photoelectric conversion module. The contents of steps 1910 and 1920 are similar to those of steps 1610 and 1620, as described in Figure 16.

[0263] Step 1930: When the duration of the wireless charging device meeting the preset interruption condition is longer than the preset duration, a first stop charging command is generated.

[0264] For example, if the duration of the wireless charging device meeting the preset interruption condition is longer than the preset duration, the wireless charging device will remain in a stopped charging state for an extended period of time. At this time, the receiving end generates a first stop charging command.

[0265] Step 1940: In response to receiving the first stop charging command from the transmitter, the connection between the power supply module and the charging beam emitting unit is disconnected by the transmitter.

[0266] For example, in response to a first stop charging command, the transmitter (such as the transmitter's control unit) generates a shutdown control signal and controls the charging beam transmitting unit to shut down according to the shutdown control signal, so that the wireless charging device enters a shutdown state, as shown in Figure 18.

[0267] When the wireless charging device is in the off state, the charging beam emitting unit is turned off and the blocking component prevents the charging beam from shining on the receiving end. When the wireless charging device is in the off state, the control unit responds to the second charging command and generates a fourth control signal and a fifth control signal. According to the fifth control signal, the control unit controls the charging beam emitting unit (e.g., charging beam transmitter) to turn on to emit the charging beam; according to the fourth control signal, the motor drives the blocking component to not block the charging beam emitting unit, so that the charging beam shines on the receiving end, and the wireless charging device enters the charging state.

[0268] When the charging beam emitting unit is turned on and the blocking member is located between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the receiving end, the control unit responds to the second charging command, generates a fourth control signal, and drives the motor according to the fourth control signal to control the blocking member not to block the charging beam emitting unit, so that the charging beam shines on the receiving end, and the wireless charging device enters the charging state.

[0269] In some embodiments of this specification, when the wireless charging device meets the preset interruption condition for an extended period of time, the receiver generates a first stop charging command, and the transmitter responds to the first stop charging command by turning off the charging beam emitting unit, which can avoid energy waste.

[0270] In some embodiments, the transmitter includes a power supply module that continuously supplies power to the charging beam emitting unit (e.g., a charging beam transmitter). When the wireless charging device meets a preset interruption condition, the shutdown control signal can be a power-off control signal or a power adjustment signal.

[0271] For example, the shutdown control signal is a power-off control signal. In response to receiving the first stop charging command from the transmitter, the control unit generates a power-off control signal and disconnects the connection between the power supply module and the charging beam transmitting unit through the transmitter to shut down the charging beam transmitting unit, thereby putting the wireless charging device into a shutdown state.

[0272] For example, the shutdown control signal is a power adjustment signal. In response to receiving the first stop charging command from the transmitter, the control unit generates a power adjustment signal and reduces the power of the charging beam emitting unit (e.g., charging beam transmitter) to a preset power through the transmitter. For example, the preset power can be 0, so as to shut down the charging beam emitting unit and make the wireless charging device enter the shutdown state.

[0273] In some embodiments of this specification, when the wireless charging device meets a preset interruption condition, a first stop charging command is generated. The preset interruption condition includes a stop charging condition and a standby state. In response to the first stop charging command, a blocking member is controlled to block the charging beam emitting unit to prevent the charging beam from shining on the receiving end. The light source can be blocked in both the standby state and the stop charging state to reduce the switching frequency of the light source and extend its service life.

[0274] For example, the working process of a wireless charging device is as follows:

[0275] In response to the first control command being a charging alignment command, such as when the photoelectric conversion module is started for the first time or when the wireless charging device is installed for the first time, the visible beam emitting unit is controlled to emit a visible beam, and the emitting end is adjusted until the position of the visible light spot is at a preset position.

[0276] After aligning the charging beam with the photoelectric conversion module, the visible beam emitting unit is turned off, and the charging beam emitting unit is controlled to emit a charging beam to charge the photoelectric conversion module.

[0277] When a wireless charging device is charging, the charging beam emitting unit can be controlled to turn on, off, or operate at a preset power based on charging protection conditions, charging recovery conditions, or normal charging conditions. For wireless charging devices with obstructions, when the device is charging, the light transmittance of the obstruction can be controlled based on preset interruption conditions, as well as the turning on, off, or operating at a preset power for the charging beam emitting unit. The priorities of multiple different conditions or commands can be preset. For example, the priority of charging protection conditions can be higher than the priority of preset interruption conditions.

[0278] Figure 20 is a structural schematic diagram of the transmitter according to some embodiments of this specification; Figure 21 is a partial structural schematic diagram of the main housing according to some embodiments of this specification; Figure 22 is a partial side view structural schematic diagram of the main housing according to some embodiments of this specification.

[0279] In some embodiments, as shown in FIG22, the wireless charging device includes a transmitter 10 and a receiver (not shown in FIG22). The transmitter 10 includes a charging beam emitting unit 13. The receiver includes a photoelectric conversion module (such as a photovoltaic cell) for converting the charging beam emitted by the charging beam emitting unit 13 into a photoelectric conversion signal.

[0280] In some embodiments, as shown in Figures 20 to 22, the transmitting end 10 further includes a visible light beam emitting unit 12.

[0281] In some embodiments, the visible beam emitting unit 12 is used to emit a visible beam to adjust the relative position of the emitting end 10 and the receiving end. The visible beam is used to form a visible light spot. The charging beam emitting unit 13 is used to form a charging light spot. The visible light spot is used to indicate the position of the charging light spot. When the emitting end 10 and the receiving end are aligned, the charging light spot illuminates the photoelectric conversion module.

[0282] In some embodiments, a charging beam forms a charging spot after illuminating the area where the receiver is located. The charging beam emitting unit and the visible beam emitting unit have a preset relative positional relationship, so that the position of the visible spot is adjacent to or at least partially overlaps with the position of the charging spot.

[0283] The visible beam emitting unit 12 and the charging beam emitting unit 13 have a preset relative positional relationship. This preset relative positional relationship indicates that the visible beam emitting unit 12 and the charging beam emitting unit 13 can move or rotate synchronously. For more information on this preset relative positional relationship, please refer to other parts of this specification, such as Figures 1-13 and their related descriptions.

[0284] In some embodiments, the transmitter 10 further includes a main housing 11 and an angle adjustment assembly 17. The visible beam emitting unit 12 and the charging beam emitting unit 13 are disposed on the main housing 11.

[0285] Angle adjustment component 17 is used to adjust the emission angle of visible beam emitting unit 12 and charging beam emitting unit 13. Angle adjustment component 17 may include a mechanism or component for adjusting the angle between the two objects. For example, angle adjustment component 17 is a gimbal disposed between visible beam emitting unit 12 and charging beam emitting unit 13.

[0286] The visible beam emitting unit 12 is used to form a visible light spot, which is used to indicate the position of the charging beam. The charging beam emitting unit can form a charging light spot (i.e., the illumination area of ​​the charging beam emitting unit in the area where the receiving end is located), and the visible light spot is used to indicate the position of the charging light spot.

[0287] The main housing 11 refers to a shell-shaped component with a certain volume. A certain space can be provided inside the main housing 11 for installing and accommodating other components. For example, other components include the visible beam emitting unit 12, the charging beam emitting unit 13, and shielding components.

[0288] For more information on the transmitter, receiver, charging beam emitting unit, and visible beam emitting unit, please refer to other parts of this specification, such as Figures 1-11 and their related descriptions.

[0289] The wireless charging device provided in some embodiments of this specification involves mounting both a visible beam emitting unit 12 and a charging beam emitting unit 13 on the main housing 11, while connecting the receiver 20 to the power-consuming device. During charging, the charging beam emitted by the charging beam emitting unit 13 illuminates a photoelectric conversion module (such as a photovoltaic cell), which converts the energy carried in the charging beam into electrical energy. Simultaneously, the main housing 11 also has a visible beam emitting unit 12, which forms a visible light spot. This visible light spot indicates the position of the charging light spot, allowing for clear and intuitive identification of its location. Furthermore, if the position of the charging light spot deviates, the angle adjustment component 17 adjusts the emission angles of the visible beam emitting unit 12 and the charging beam emitting unit 13, making alignment between the transmitter 10 and the receiver 20 easier.

[0290] In some embodiments, as shown in Figures 20 and 21, a channel 18 is provided within the main housing 11, through which the charging beam emitted by the charging beam emitting unit 13 passes. A mounting portion 14 is provided within the channel 18. The mounting portion 14 is located at the central axis of the channel 18. For example, the axis of the mounting portion 14 coincides with the axis of the channel 18. The mounting portion 14 is used to mount and fix the visible beam emitting unit 12, and the mounting portion 14 is located at the center of the cross-section of the channel 18.

[0291] Channel 18 refers to a receiving structure with a certain length. Both ends of channel 18 can be open structures. The charging beam emitting unit 13 can be located at one end of channel 18, and the charging beam emitted by the charging beam emitting unit 13 can be emitted from the other end after passing through channel 18. Mounting part 14 refers to a structure or component that can fix other objects. Mounting part 14 can be a clamping tube, clamping groove, or clamping hole, etc.

[0292] A channel 18 is provided within the main housing 11, allowing the charging beam emitted by the charging beam emitting unit 13 to pass through the channel 18 and illuminate the photoelectric conversion module, thus making the shape of the charging beam spot circular under the action of the channel 18. Simultaneously, a mounting part 14 is provided within the channel 18, located at the center of the channel 18's cross-section. The visible beam emitting unit 12 can be mounted at the center of the channel 18's cross-section via the mounting part 14, thereby positioning the visible beam spot at the center of the charging beam spot. The visible beam spot indicates the center position of the charging beam spot, making it easier to determine its location and improving alignment accuracy.

[0293] In some embodiments, as shown in FIG21, the mounting portion 14 includes an insertion cylinder portion 141. The insertion cylinder portion 141 refers to a cylindrical component with a certain length. The insertion cylinder portion 141 may have an opening at one end, or it may have openings at both ends. The visible beam emitting unit 12 is inserted into the insertion cylinder portion 141 through the opening at the end of the insertion cylinder portion 141, making the installation of the visible beam emitting unit 12 more convenient and secure.

[0294] It should be noted that a clearance opening is also provided on the side wall of the insert cylinder 141. The clearance opening is used to avoid the operating switch on the visible beam emitting unit 12, making the installation of the visible beam emitting unit 12 more convenient.

[0295] In some embodiments, as shown in Figures 21 and 22, a plurality of support members 16 are also connected between the insert cylinder 141 and the inner wall of the channel 18. The support member 16 refers to a component with a certain volume, and can be block-shaped, column-shaped, or plate-shaped, etc. By connecting the insert cylinder 141 to the inner wall of the channel 18 through multiple support members 16, the installation of the insert cylinder 141 in the channel 18 can be more secure, and also more stable and reliable.

[0296] In some embodiments, the support member 16 can be plate-shaped, arranged radially along the mounting cylinder, and parallel to the axis of the channel 18. The support member 16 being plate-shaped means that it is a component with a certain thickness. By setting the support member 16 to be plate-shaped, and simultaneously arranging it radially along the channel 18 and parallel to its axis, the support member 16 can support the insertion cylinder portion 141 while reducing its area in the direction of the charging beam, avoiding excessive obstruction of the charging beam, increasing the overall area of ​​the charging spot, and improving the charging efficiency of the wireless charging device.

[0297] Figure 23 is a partial structural schematic diagram of the main housing according to some embodiments of this specification; Figure 24 is a structural schematic diagram of the angle adjustment assembly according to some embodiments of this specification.

[0298] In some embodiments, as shown in FIG23, the visible beam emitting unit 12 includes a plurality of visible beam emitters (e.g., emitting sub-sections 121), and the plurality of visible beam emitters correspondingly form a plurality of sub-spots. The charging beam is located at the center of the plurality of sub-spots. At this time, the visible beam consists of a plurality of sub-spots. Each emitting sub-section 121 corresponds one-to-one with each sub-spot, and each sub-spot is located on the outer periphery of the charging beam. The emitting sub-section 121 refers to a component or assembly that can emit visible light, and the emitting sub-section 121 can be a laser emitter. A sub-spot refers to a beam area with a certain area.

[0299] A visible beam emitting unit 12 is composed of multiple visible beam emitters, and each emitting sub-unit 121 forms a sub-spot, so that each emitting sub-unit 121 corresponds one-to-one with each sub-spot. At the same time, each sub-spot is located on the outer periphery of the charging spot, and the outline of the charging spot can be clearly indicated by the sub-spots, making it easier to determine the position of the charging spot, thereby improving the alignment accuracy.

[0300] In some embodiments, as shown in FIG23, a channel 18 is provided inside the main housing 11, and the charging beam emitted by the charging beam emitting unit 13 passes through the channel 18. A plurality of mounting portions 14 are provided around the channel 18 on the main housing 11, and a plurality of visible beam emitters (e.g., a plurality of emitting sub-parts 121) are respectively mounted in the plurality of mounting portions 14.

[0301] By providing multiple mounting portions 14 around the channel 18 on the main housing 11, mounting positions can be provided for multiple visible beam emitters, allowing the sub-spots formed by the emitting sub-section 121 to be located on the outer periphery of the charging spot. This clearly indicates the outline of the charging spot through the sub-spots, making it easier and faster to determine the position of the charging spot, thereby improving the accuracy of alignment between the emitting end 10 and the receiving end 20.

[0302] It should be noted that the charging beam emitting unit 13 and the visible beam emitting unit 12 can also be configured in other ways, for example, as shown in Figures 2 to 10. Correspondingly, the configuration of the channel 18 and the mounting part 14 can be matched with that of the charging beam emitting unit 13 and the visible beam emitting unit 12.

[0303] In some embodiments, please refer to FIG20, the main housing 11 includes a first housing 111 and a second housing 112, the charging beam emitting unit 13 is disposed on the first housing 111, the visible beam emitting unit 12 is disposed on the second housing 112, and the second housing 112 is detachably connected to the first housing 111.

[0304] Both the first housing 111 and the second housing 112 refer to shell-shaped components with a certain volume, and the first housing 111 and the second housing 112 can be detachably connected by means of plug-in, snap-fit, or threaded connection. The charging beam emitting unit 13 is disposed on the first housing 111, and the visible beam emitting unit 12 is disposed on the second housing 112. The second housing 112 is detachably connected to the first housing 111. When alignment is required using the visible beam emitting unit 12, the first housing 111 is connected to the second housing 112. After adjustment, the first housing 111 is removed from the second housing 112 to prevent the visible beam emitting unit 12 from obstructing the charging beam.

[0305] In some embodiments, as shown in FIG20, the first housing 111 has a first connecting portion 1111, and the second housing 112 has a second connecting portion 1121, and the first connecting portion 1111 and the second connecting portion 1121 are detachably connected. For example, the first connecting portion 1111 and the second connecting portion 1121 are threadedly connected. The first connecting portion 1111 refers to a component with a certain volume, and the first connecting portion 1111 can be cylindrical or cylindrical, etc. The second connecting portion 1121 can also be a component with a certain volume. When the first connecting portion 1111 is cylindrical, the second connecting portion 1121 can be cylindrical. By having the first connecting portion 1111 on the first housing 111 and the second connecting portion 1121 on the second housing 112, and by the threaded connection between the first connecting portion 1111 and the second connecting portion 1121, a detachable connection between the first housing 111 and the second housing 112 can be achieved, making the disassembly and connection of the two more convenient.

[0306] In some embodiments, as shown in Figures 21 to 23, the second housing 112 is generally cylindrical, and the second connecting portion 1121 can be one end of the second housing 112. The first connecting portion 1111 is a columnar portion on the first housing 111, which can be fitted onto the outside of the first connecting portion 1111 on the first housing 111, and the inner wall of the second housing 112 is threadedly connected to the outer wall of the first connecting portion 1111, making it easier to connect the first housing 111 and the second housing 112.

[0307] In some embodiments, as shown in Figures 20 and 24, the angle adjustment assembly 17 includes a fixed base 171, a rotating ball 172, and a connector 173. The fixed base 171 is provided with a mounting recess 174 for accommodating the rotating ball 172. The rotating ball 172 is rotatably fitted inside the mounting recess 174. One end of the connector 173 is connected to the rotating ball 172, and the other end is connected to the main housing 11.

[0308] The mounting base 171 refers to a component with a certain volume. The mounting base 171 can be installed to a wall or other fixed location by means of plug-in, snap-in, or fastener connection. The rotating ball 172 refers to a spherical structure with a certain diameter. The mounting recess 174 refers to a mounting part 14 with a certain accommodating space. The internal shape of the mounting recess 174 matches the rotating ball 172, allowing the rotating ball 172 to rotate within the mounting recess 174. The connector 173 refers to a component with a certain length. The connector 173 can be rod-shaped, column-shaped, or plate-shaped. The connector 173 can be a separate structure from the rotating ball 172, connected by plug-in or threaded connection, or the connector 173 can be an integral structure with the rotating ball 172. The other end of the connector 173 can be connected to the main housing 11 by plug-in, snap-in, or threaded connection.

[0309] A mounting recess 174 is provided on the fixed base 171, and a rotating ball 172 is rotatably positioned within the mounting recess 174. One end of a connector 173 is connected to the rotating ball 172, and the other end is connected to the charging beam emitting unit's emitting assembly. The connector 173 is ball-connected to the fixed base 171 via the rotating ball 172. When the illumination angle of the charging beam emitting unit 13 and the visible beam emitting unit 12 needs adjustment, the illumination angle can be adjusted by rotating the connector 173.

[0310] In some embodiments, the visible beam emitted by the visible beam emitting unit 12 is a laser, and the charging beam emitted by the charging beam emitting unit 13 is infrared light. A laser is a beam with an extremely small divergence angle and high energy density. The charging beam emitted by the charging beam emitting unit 13 can also be a laser or other beams with relatively high energy density.

[0311] For more information on lasers and infrared light, please refer to other parts of this manual, such as Figures 1-10 and their related descriptions.

[0312] By using laser light as the visible beam, the visible beam can be more focused, preventing it from diverging over long distances and thus affecting the area of ​​the visible light spot. Using infrared light as the charging beam, due to its small divergence angle and good monochromaticity, allows the charging beam to carry more energy at the same power, thereby improving energy transfer efficiency.

[0313] In some embodiments, as shown in FIG20, a collimating lens 15 is also provided on the main housing 11, and the charging beam emitting unit 13 is located at the focal point of the collimating lens 15.

[0314] By providing a collimating lens 15 on the main housing 11 and placing the charging beam emitting unit 13 at the focal point of the collimating lens 15, the charging beam emitted by the charging beam emitting unit 13 is emitted after being refracted by the collimating lens 15, thereby making the divergence angle of the charging beam smaller.

[0315] It should be noted that the collimating lens 15 can be part of the first housing 111. When the collimating lens 15 is present, the second housing 112 can be cylindrical, and the second housing 112 can be fitted onto the end of the collimating lens 15. The inner wall of the second housing 112 is threadedly connected to the outer wall of the collimating lens 15, making the installation of the second housing 112 more secure.

[0316] In some embodiments, the transmitter 10 further includes a blocking member. For example, the blocking member may be disposed outside the first housing 111 and driven to the charging beam emitting unit 13 or the transmitter 10 via a driving device (such as a motor or cylinder). For instance, the blocking member may be slidable relative to the transmitter 10, capable of blocking the channel 18, thereby blocking the charging beam.

[0317] In some embodiments, the transmitter 10 further includes a motor drivenly connected to the blocking member. The motor is used to control the blocking member to rotate or translate between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the photoelectric conversion module, or to control the two blocking members to move towards each other between the light-emitting surface of the charging beam emitting unit and the photosensitive surface of the photoelectric conversion module. For more information about the blocking member and the motor, please refer to other parts of this specification, such as Figures 14-19 and their related descriptions.

[0318] In some embodiments, the wireless charging device may include a control module and a position adjustment module.

[0319] In some embodiments, the control module is used to control the visible beam emitting unit on the transmitting end to emit a visible beam, and the visible beam forms a visible light spot after illuminating the area where the receiving end is located.

[0320] In some embodiments, the position adjustment module is used to adjust the emitting end until the position of the visible light spot is at a preset position, the preset position being used to characterize the area where the photovoltaic cell is located.

[0321] In some embodiments, the visible beam emitting unit includes two sets of visible beam emitting subunits, and the visible light spot includes a first light spot and a second light spot; the visible beam emitted by the first set of visible beam emitting subunits forms the first light spot; the visible beam emitted by the second set of visible beam emitting subunits forms the second light spot; the control module can also be specifically used for:

[0322] Adjust the emitting end to adjust the position of the first light spot and the position of the second light spot until the photovoltaic cell is between the first light spot and the second light spot.

[0323] In some embodiments, the control module can also be used to: control the visible beam emitting unit to turn off; control the charging beam emitting unit in the emitting end to emit a beam at a preset power to charge the photovoltaic cell on the receiving end.

[0324] In some embodiments, the visible beam emitting unit includes a plurality of visible beam emitters arranged around the charging beam emitting unit, and the visible light spot includes a plurality of sub-spots, with the plurality of visible beam emitters corresponding to form the plurality of sub-spots; the control module may further be used to: adjust the emitting end to adjust the spot positions of the plurality of sub-spots until the spot positions of the plurality of sub-spots are around the photovoltaic cell.

[0325] In some embodiments, the control module may further be used to: adjust the transmitting end to adjust the position of the visible light spot until the position of the visible light spot is at the center of the photovoltaic cell.

[0326] This specification also provides a wireless charging device in some embodiments, which is applied in a wireless charging equipment. The wireless charging device includes a determining module and a control module.

[0327] In some embodiments, the determining module is used to determine whether the wireless charging device meets the charging protection conditions, the charging recovery conditions, and the normal charging conditions.

[0328] In some embodiments, the control module is configured to control the charging beam emitting unit to stop emitting a beam in response to the wireless charging device meeting the charging protection condition; control the charging beam emitting unit to emit a beam at a first power in response to the wireless charging device meeting the resumption charging condition; and control the charging beam emitting unit to emit a beam at a second power, wherein the second power is greater than the first power, in response to the wireless charging device meeting the normal charging condition.

[0329] In some embodiments, the conditions for resuming charging include at least one of the following: the current time is within the charging period, no human body is detected within the beam radiation area, the door lock is closed, and the remaining power of the receiver is less than a preset power level.

[0330] In some embodiments, normal charging conditions include being in a charging period at the current time, no human body being detected within the beam radiation area, the door lock being closed, and the remaining power of the receiver being less than a preset power level.

[0331] In some embodiments, the determining module is further configured to determine whether the wireless charging device meets normal charging conditions based on whether a photoelectric conversion signal is detected at the receiving end.

[0332] In some embodiments, the determining module is further configured to determine the charging period based on the user's historical work and rest schedule and historical travel time; and to adjust the charging period based on user habits and user settings information, including whether to set up hourly workers and / or whether to set up a courier service mode.

[0333] In some embodiments, the control method further includes the following steps S101 to S104.

[0334] S101, when the wireless charging system (the control system of the wireless charging device) meets the preset conditions, it receives the first stop charging command generated by the receiving end.

[0335] The preset conditions include preset charging stop conditions and standby mode.

[0336] For example, the preset charging stop condition can be one, such as any one of the following: the current time is outside the preset charging period, a human body is detected within the beam radiation area, the remaining power of the receiver is greater than a preset power, and the receiver detects a photoelectric conversion signal. When the wireless charging system in the charging state meets the preset charging stop condition, the receiver generates a first charging stop command and sends the first charging stop command to the transmitter.

[0337] In other embodiments, there can be multiple preset charging stop conditions. For example, preset charging stop conditions may include multiple conditions such as being outside a preset charging period, detecting a human body within the beam radiation area, having a remaining battery power greater than a preset battery power, and not detecting a photoelectric conversion signal at the receiver. When the wireless charging system in the charging state meets any one of the preset charging stop conditions, the receiver generates a first charging stop command.

[0338] If the preset charging stop condition includes the current time being outside the preset charging period, the preset charging period can be a user-preset charging period. For example, the receiving end includes a setting module, and the user sets the preset charging period based on the setting module, or the user sets the preset charging period based on the smart terminal and sends it to the receiving end. Alternatively, the preset charging period can be a charging period determined based on historical charging time. For example, the receiving end determines the preset charging period based on stored historical charging time, or the smart terminal determines the preset charging period based on stored historical charging time and sends the preset charging period to the receiving end.

[0339] If the preset charging stop condition includes that the remaining power of the receiver is greater than the preset power, where the preset power can be any value between 90% and 100%, then when the remaining power of the receiver is greater than the preset power, the receiver does not need to be charged.

[0340] If the preset charging stop condition includes the detection of a human body within the beam radiation area, and the transmitter or receiver includes a sensor, it can determine whether a human body is detected within the beam radiation area based on the information collected by the sensor. When a human body is detected within the beam radiation area, the risk of harm to the human body is relatively high.

[0341] For example, a distance sensor such as a time-of-flight (TOF) sensor, radar sensor, or ultrasonic sensor can measure the distance between a human body and the sensor. When the distance between the human body and the sensor is less than the distance between the edge of the beam's radiation area and the sensor, a human body is detected within the beam's radiation area. Alternatively, an image sensor can capture an image within the beam's radiation area; if the captured image includes a human body, a human body is detected within the beam's radiation area. Or, a passive infrared (PIR) sensor can collect thermal radiation signals within the beam's radiation area; when thermal radiation signals are detected, a human body is detected within the beam's radiation area.

[0342] If the preset charging stop condition includes the receiver not detecting a photoelectric conversion signal, the smart door lock is in the open state or there is a problem with the alignment between the transmitter and receiver when the receiver does not detect a photoelectric conversion signal.

[0343] When the wireless charging system enters standby mode while charging, the receiver will generate a first stop charging command and send the first stop charging command to the transmitter.

[0344] S102, in response to the first stop charging command, controls the blocking member to block the light source to prevent the light beam emitted by the light source from shining on the receiver.

[0345] For example, the transmitter includes a control module and a motor. When the wireless charging system is in a charging state, if the transmitter receives a first stop charging command generated by the receiver, the control module responds to the first stop charging command, generates a first control signal, and drives the motor to rotate in a first clockwise direction according to the first control signal. For example, the first clockwise direction can be clockwise or counterclockwise.

[0346] The motor is connected to the blocking component. The rotation of the motor in the first clockwise direction can move the blocking component between the light-emitting surface of the light source and the photosensitive surface of the receiver, thereby preventing the light beam emitted by the light source from shining on the receiver, so that the wireless charging system enters the stopped charging state, as shown in Figure 14.

[0347] When the wireless charging system in the stopped charging state meets the preset charging conditions, the receiver generates a charging command and sends the charging command to the transmitter. In response to the charging command, the transmitter controls the blocking device not to block the light source so that the light beam emitted by the light source can shine on the receiver.

[0348] For example, the preset charging condition can be one, such as the current time being within a preset charging period, no human body being detected within the beam radiation area, the remaining power of the receiver being less than the preset charging power, and the receiver detecting a photoelectric conversion signal, wherein the preset charging power is less than the preset power.

[0349] In other embodiments, there can be multiple preset charging conditions. For example, preset charging conditions include being within a preset charging period, no human body being detected within the beam radiation area, the remaining power of the receiver being less than a preset charging amount, and the receiver detecting a photoelectric conversion signal. When the wireless charging system in the stopped charging state meets all preset charging conditions, the receiver generates a charging command.

[0350] If the preset charging conditions include being within a preset charging period and no human body being detected within the beam's radiation area, the receiver generates a charging command when the current time of the wireless charging system is within the preset charging period and no human body is detected within the beam's radiation area.

[0351] If the preset charging conditions include being in a preset charging period, no human body being detected within the beam radiation area, and the remaining power of the receiver being less than the preset charging power, the receiver generates a charging command when the current time of the wireless charging system is within the preset charging period, no human body is detected within the beam radiation area, and the remaining power of the receiver is less than the preset charging power.

[0352] If the preset charging conditions include being in a preset charging period, no human body being detected within the beam radiation area, the remaining power of the receiver being less than the preset charging power, and the receiver detecting a photoelectric conversion signal, then the receiver generates a charging command when the current time of the wireless charging system is within the preset charging period, no human body is detected within the beam radiation area, the remaining power of the receiver is less than the preset charging power, and the receiver detects a photoelectric conversion signal.

[0353] The control module responds to the charging command, generates a second control signal, and drives the motor to rotate in the second clockwise direction according to the second control signal, so as to remove the blocking component from the light-emitting surface of the light source and the photosensitive surface of the receiver, thereby ensuring that the light beam emitted by the light source shines on the receiver so that the wireless charging system enters the charging state, as shown in Figure 15.

[0354] The second clockwise direction is the opposite of the first clockwise direction. For example, if the first clockwise direction is clockwise, then the second clockwise direction is counterclockwise, and if the first clockwise direction is counterclockwise, then the second clockwise direction is clockwise.

[0355] In this embodiment of the disclosure, when the wireless charging system meets preset conditions, it receives a first stop charging command generated by the receiving end. The preset conditions include preset stop charging conditions and a standby state. In response to the first stop charging command, the blocking member is controlled to block the light source to prevent the light beam emitted by the light source from shining on the receiving end. The light source can be blocked in both the standby state and the stop charging state to reduce the switching frequency of the light source and extend the service life of the light source.

[0356] Based on the above embodiments, the plane where the blocking member is located is perpendicular to the optical axis of the light beam. The blocking member can rotate in the plane perpendicular to the optical axis. For example, the blocking member can rotate clockwise in the plane perpendicular to the optical axis, and it can also rotate counterclockwise in the plane perpendicular to the optical axis.

[0357] A specific description of one possible implementation of S102 is as follows:

[0358] In response to the first stop charging command, the blocking member is controlled to rotate or translate between the light-emitting surface of the light source and the photosensitive surface of the receiver.

[0359] For example, in response to the first stop charging command, the control module generates a first control signal and drives the motor to rotate in a first clockwise direction according to the first control signal. The rotation of the motor in the first clockwise direction can drive the blocking member to rotate in a third clockwise direction in a plane perpendicular to the optical axis to the space between the light-emitting surface of the light source and the photosensitive surface of the receiving end, as shown in Figure 14. For example, the third clockwise direction can be clockwise or counterclockwise.

[0360] The control module responds to the charging command, generates a second control signal, and drives the motor to rotate in the second clockwise direction according to the second control signal. The rotation of the motor in the second clockwise direction can drive the blocking component to rotate and move out from between the light-emitting surface of the light source and the photosensitive surface of the receiving end in the fourth clockwise direction in a plane perpendicular to the optical axis, as shown in Figure 15.

[0361] The fourth clockwise direction is the opposite of the third clockwise direction. For example, if the third clockwise direction is clockwise, then the fourth clockwise direction is counterclockwise, and vice versa.

[0362] In other embodiments, the rotation of the motor in the first clockwise direction can cause the blocking member to translate in a plane perpendicular to the optical axis to between the light-emitting surface of the light source and the photosensitive surface of the receiver, as shown in Figure 14. The rotation of the motor in the second clockwise direction can cause the blocking member to translate out from between the light-emitting surface of the light source and the photosensitive surface of the receiver in a plane perpendicular to the optical axis, as shown in Figure 15.

[0363] It should be noted that Figures 14 and 15 only exemplarily show that the shielding member 120 is located outside the light source 110. In practical applications, the shielding member 120 can also be located inside the light source 110. This disclosure does not impose any specific limitations on this.

[0364] As a specific description of another possible implementation when executing S102, the following is an example:

[0365] In response to the first stop charging command, the two blocking elements are controlled to move towards each other between the light-emitting surface of the light source and the photosensitive surface of the receiver.

[0366] For example, the transmitter includes two blocking members. The two blocking members can move towards each other in a plane perpendicular to the optical axis, and can also move away from each other in a plane perpendicular to the optical axis. The rotation of the motor in a first clockwise direction can control the two blocking members to move towards each other in a plane perpendicular to the optical axis to between the light-emitting surface of the light source and the photosensitive surface of the receiver. The rotation of the motor in a second clockwise direction can drive the two blocking members to move away from each other in a plane perpendicular to the optical axis from between the light-emitting surface of the light source and the photosensitive surface of the receiver.

[0367] Based on the above embodiments, the plane where the blocking member is located is perpendicular to the optical axis of the light beam, the blocking member is fixed between the light-emitting surface of the light source and the photosensitive surface of the receiving end, and the light transmittance of the blocking member is adjustable.

[0368] As a specific description of another possible implementation when executing S102, the following is an example:

[0369] In response to the first stop charging command, the transmittance of the blocking element located between the light-emitting surface of the light source and the photosensitive surface of the receiver is reduced.

[0370] For example, in response to the first stop charging command, the control module reduces the transmittance of the blocking element to reduce the light intensity received by the receiver, and in response to the charging command, the control module increases the transmittance of the blocking element to increase the light intensity received by the receiver.

[0371] In some embodiments, the control method further includes:

[0372] S103, when the receiving end receives the light beam emitted by the light source, it receives the second stop charging command generated by the receiving end.

[0373] For example, when the wireless charging system is in a stopped charging state, if the receiver still receives the light beam emitted by the light source and the blocking component fails to completely block the light beam emitted by the light source, then the blocking component is abnormal, that is, there is still a certain safety hazard. At this time, the receiver generates a second stop charging command.

[0374] S104, in response to the second stop charging command, controls the light source to turn off.

[0375] For example, in response to the second stop charging command, the receiving end generates a shutdown control signal and controls the light source to turn off according to the shutdown control signal, so that the wireless charging system enters the shutdown state, as shown in FIG18. FIG18 is a schematic diagram of the structure of the wireless charging system in the shutdown state provided in the embodiment of the present disclosure.

[0376] When the wireless charging system is in the off state, the light source is off and the blocking component prevents the light beam emitted by the light source from shining on the receiver. The control module responds to the charging command and generates a second control signal and a third control signal. According to the third control signal, the light source is turned on so that it emits a light beam. According to the second control signal, the motor is driven to control the blocking component to not block the light source so that the light beam emitted by the light source shines on the receiver, so that the wireless charging system enters the charging state.

[0377] When the wireless charging system is in a stopped charging state, the light source is turned on and the blocking component is located between the light-emitting surface of the light source and the photosensitive surface of the receiver. The control module responds to the charging command, generates a second control signal, and drives the motor according to the second control signal to control the blocking component to not block the light source, so that the light beam emitted by the light source shines on the receiver, and the wireless charging system enters the charging state.

[0378] Thus, when the obstruction malfunctions, the receiver generates a second stop charging command, and the transmitter responds to the second stop charging command by turning off the light source, which can improve the safety of the wireless charging system.

[0379] In some embodiments, the wireless charging method (control method for a wireless charging device) further includes:

[0380] S103' When the duration for which the wireless charging system meets the preset stop charging condition is longer than the preset duration, the system receives the second stop charging command generated by the receiver.

[0381] For example, when the wireless charging system is in a stopped charging state, if the duration for which the wireless charging system meets the preset stopped charging conditions is longer than the preset duration, the wireless charging system will remain in a stopped charging state for an extended period of time. At this time, the receiving end generates a second stop charging command.

[0382] S104, in response to the second stop charging command, controls the light source to turn off.

[0383] For example, in response to the second stop charging command, the receiver generates a shutdown control signal and controls the light source to turn off according to the shutdown control signal, so that the wireless charging system enters the shutdown state, as shown in Figure 18.

[0384] When the wireless charging system is in the off state, the light source is off and the blocking component prevents the light beam emitted by the light source from shining on the receiver. The control module responds to the charging command and generates a second control signal and a third control signal. According to the third control signal, the light source is turned on so that it emits a light beam. According to the second control signal, the motor is driven to control the blocking component to not block the light source so that the light beam emitted by the light source shines on the receiver, so that the wireless charging system enters the charging state.

[0385] When the wireless charging system is in a stopped charging state, the light source is turned on and the blocking component is located between the light-emitting surface of the light source and the photosensitive surface of the receiver. The control module responds to the charging command, generates a second control signal, and drives the motor according to the second control signal to control the blocking component to not block the light source, so that the light beam emitted by the light source shines on the receiver, and the wireless charging system enters the charging state.

[0386] Thus, when the wireless charging system is in a state of not charging for a long time, the receiver generates a second stop charging command, and the transmitter responds to the second stop charging command by turning off the light source, which can avoid energy waste.

[0387] Based on the above embodiments, the transmitter includes a power supply module. When the wireless charging system is in a stopped charging state, the power supply module continuously supplies power to the light source. The shutdown control signal can be a power-off control signal or a power adjustment signal.

[0388] As a specific description of one possible implementation when executing S104, the following is an example:

[0389] In response to the second stop charging command, the connection between the power supply module and the light source is disconnected.

[0390] For example, the shutdown control signal is a power-off control signal. In response to the second stop charging command, the control module generates a power-off control signal and disconnects the connection between the power supply module and the light source according to the power-off control signal to turn off the light source, so that the wireless charging system enters the shutdown state.

[0391] As a specific description of another possible implementation when executing S104, the following is an example:

[0392] In response to the second stop charging command, the power of the control light source is reduced to a preset power.

[0393] For example, the shut-off control signal is a power adjustment signal. In response to the second stop charging command, the control module generates a power adjustment signal and reduces the power of the light source to a preset power according to the power adjustment signal. For example, the preset power can be 0, so as to turn off the light source and make the wireless charging system enter the shut-off state.

[0394] In some embodiments, the receiving module is configured to receive a first stop charging command generated by the receiving end when the wireless charging device meets preset conditions, the preset conditions including preset stop charging conditions and being in a standby state. The control module is configured to, in response to the first stop charging command, control a blocking member to block the light source to prevent the light beam emitted by the light source from shining onto the receiving end.

[0395] In some embodiments, the control module is further configured to, in response to a first stop charging command, control the blocking member to rotate or translate between the light-emitting surface of the light source and the photosensitive surface of the receiver.

[0396] In some embodiments, the control module is further configured to, in response to a first stop charging command, control two blocking members to move toward each other between the light-emitting surface of the light source and the photosensitive surface of the receiver.

[0397] In some embodiments, the control module is further configured to reduce the transmittance of the blocking member located between the light-emitting surface of the light source and the photosensitive surface of the receiver in response to a first stop charging command.

[0398] In some embodiments, the receiving module is further configured to receive a second stop charging command generated by the receiving end when the receiving end receives a light beam emitted by the light source; the control module is further configured to control the light source to turn off in response to the second stop charging command.

[0399] In some embodiments, the receiving module is further configured to receive a second stop charging command generated by the receiving end when the duration for which the wireless charging device meets the preset stop charging condition is longer than the preset duration; the control module is further configured to control the light source to turn off in response to the second stop charging command.

[0400] In some embodiments, the control module is further configured to disconnect the power supply module from the light source in response to a second stop charging command.

[0401] In some embodiments, the control module is further configured to control the power of the light source to be reduced to a preset power in response to a second stop charging command.

[0402] In some embodiments, the preset charging stop conditions include at least one of the following: the current time is outside the preset charging period, a human body is detected within the beam radiation area, the remaining power of the receiver is greater than the preset power, and the receiver does not detect a photoelectric conversion signal.

[0403] In some embodiments, the preset charging conditions include at least one of the following: the current time is within a preset charging period, no human body is detected within the beam radiation area, the remaining power of the receiver is less than the preset charging power, and the receiver detects a photoelectric conversion signal, wherein the preset charging power is less than the preset power.
