Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
The embodiment of the application provides a wireless charging device and a wireless charging system. The details will be described below separately.
Referring to fig. 1 and fig. 2, fig. 1 is a block diagram illustrating a wireless charging system according to an embodiment of the present disclosure, and fig. 2 is a structural diagram illustrating the wireless charging system according to the embodiment of the present disclosure. The wireless charging device 200 includes a first wireless receiving module 210, a power storage module 220, and a first wireless transmitting module 230.
The first wireless receiving module 210 is configured to receive a first wireless charging signal through a first wireless charging manner, and convert the first wireless charging signal into electric energy to be output. The first wireless charging signal is transmitted by the wireless transmission device 100 according to the first wireless charging method.
The energy storage module 220 is connected to the first wireless receiving module 210, and the energy storage module 220 is used for storing the electric energy output by the first wireless receiving module 210. The energy storage module 220 may be a battery 320, or may be other energy storage elements, such as a large capacitor.
The first wireless transmitting module 230 is connected to the energy storage module 220, and the first wireless transmitting module 230 is configured to convert the electric energy into a second wireless charging signal and transmit the second wireless charging signal in a second wireless charging manner. The second wireless charging signal is used to charge the device 300 to be charged.
The first wireless charging signal is transmitted in a first wireless charging mode to have a first maximum effective distance, the second wireless charging signal is transmitted in a second wireless charging mode to have a second maximum effective distance, and the first maximum effective distance is larger than the second maximum effective distance.
Specifically, the first wireless charging mode may be a long-distance wireless charging mode, and the first maximum effective distance may be at least 5 meters, for example, the first maximum effective distance may be 3 meters, 4 meters, 5 meters, 8 meters, or 10 meters. The second wireless charging mode can be a short-distance wireless charging mode, and the second maximum effective distance is smaller. For example, the second maximum effective distance may be 50 cm, 30 cm, or 20 cm, etc., and may even be 10 cm, 5 cm, or 2 cm, etc.
Here, the first maximum effective distance means that a better conversion rate can be obtained within the first maximum effective distance when the wireless charging is performed by the first wireless charging method. For example, within the first maximum effective distance, a conversion rate higher than the conversion threshold may be acquired by the first wireless charging manner. The wireless transmitting device 100 sends out a first wireless charging signal with a first energy value through a first wireless charging mode, the wireless charging device 200 obtains the first wireless charging signal and converts the first wireless charging signal into electric energy with a second energy value, and a ratio of the second energy value to the first energy value can be understood as a conversion rate. The switching threshold may be 50%, 60%, 70%, 80%, or the like. If the conversion rate is too low, such as 20%, or even lower, the conversion efficiency is too low, and the practical effect is not good.
The second maximum effective distance has a similar effect to the first maximum effective distance, and is not described herein again. Because the second maximum effective distance is much smaller than the first maximum effective distance, the transition threshold corresponding to the second maximum effective distance may be larger than the transition threshold corresponding to the first maximum effective distance.
In the description of the present application, it is to be understood that the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
Thus, the wireless charging device 200 can be moved arbitrarily within a wide range, and the device 300 to be charged can move along with the wireless charging device 200 without being limited by the commercial power interface. For example, the wireless transmitting device 100 may be disposed at the top of a room, and the first maximum effective distance is 5 meters, so that the wireless charging device 200 and the device 300 to be charged may move arbitrarily within a range of 5 meters of a square circle with the wireless transmitting device 100 as a base point, and thus wireless charging may be well achieved. In the related art, the wireless charging base is connected with the mains supply interface through a cable, the wireless charging base can only be within the cable length range of the mains supply interface, and the wireless charging base also needs a placement platform (such as a desk) to further compress the selection space of the charging position. The wireless charging device 200 in the embodiment of the present application can be moved at will in a relatively large range, assuming that the indoor height is 3 meters, the wireless transmitting device 100 is located at the center of the ceiling of the room, and the first maximum effective distance is 5 meters, at least 16 square meters can be radiated, if the wireless charging device 200 is placed on furniture such as a desk, an area larger than 16 square meters can be radiated, and a room can be completely covered, so that the wireless charging device 300 can be wirelessly charged at any position in the room, which is very convenient. If a larger space such as a living room or an office is provided, a plurality of wireless transmission devices 100 may be provided to realize full coverage of the larger space, and the corresponding wireless charging device 200 and the device 300 to be charged may also move arbitrarily in the larger space.
The charging device is generally placed on an office table, a bed, a sofa, a tea table, a television cabinet or a dining frame, and the like, the wireless charging base in the related technology needs to be connected with a mains supply interface through a cable, if the wireless charging can be realized in the position, a great number of wireless charging bases need to be arranged, and the mains supply interface is arranged beside the position, so that the wireless charging base is obviously difficult to realize. In addition, some places are bigger, for example, on the bed, the wireless charging base is arranged at the head of the bed, and the wireless charging is difficult to realize at the tail of the bed and in the middle of the bed. Moreover, when moving from one location to another, a wireless charging base or a commercial power interface needs to be found again, and charging cannot be achieved in the finding process, and the wireless charging base or the commercial power interface cannot be found. The wireless charging device in the embodiment can move freely within the first maximum effective distance, so that the device to be charged can also move freely along with the wireless charging device, and wireless charging can be realized at any position on the bed like on the bed. When moving from one position to another position, wireless charging device can charge for the device of treating that charges ceaselessly, also need not change wireless charging device, also need not look for commercial power interface. As long as the wireless charging device is within the first maximum effective distance of the wireless transmitting device. In this case, the wireless charging can be performed at any position in the activity area if the plurality of wireless transmission devices can cover the entire activity area, for example, the entire residential area or the entire office area.
In some embodiments, the first wireless charging mode is a wireless optical charging mode, the first wireless charging signal is an optical signal, the second wireless charging mode is a wireless electromagnetic charging mode, and the second wireless charging signal is an electromagnetic signal.
The wireless optical charging method is that the wireless transmitting device 100 transmits an optical signal, and the wireless charging device 200 receives the optical signal and converts the optical signal into electric energy. The optical signal may be a visible light signal or an invisible light signal, and the optical signal may also be a laser signal, an infrared light signal, or the like. The wireless charging by the optical signal can realize the wireless charging at a longer distance.
The wireless electromagnetic charging mode can be a magnetic resonance wireless charging mode or an electric field coupling wireless charging mode. Currently, the mainstream wireless charging standards include QI standard, power association (PMA) standard, and wireless power association (A4 WP) standard. The QI standard and the PMA standard both adopt a magnetic coupling mode for wireless charging. The A4WP standard uses magnetic resonance for wireless charging. When the wireless electromagnetic charging mode is utilized for short-distance wireless charging, good conversion rate can be obtained.
