Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In view of the problem that the convenience of the conventional wireless charging device still needs to be improved, the embodiment of the invention provides a remote wireless power supply device, method and system, which can be applied to improving the convenience of the wireless charging device.
An embodiment of the present invention provides a remote wireless power supply apparatus, referring to a schematic structural diagram of the remote wireless power supply apparatus shown in fig. 1, where the apparatus includes: the device comprises a transmitting module 11 and a transmitting control module 12, wherein the transmitting module comprises a transmitting unit 111 and an energy converging unit 112.
The emission control module 12 is configured to control a direction and/or an angle of the electromagnetic wave emitted by the emission module according to a position of the device to be charged. The transmission control module 12 is communicatively connected to the transmission module 11, and sends a control signal, such as a pulse signal, an analog signal, or a digital signal, to the transmission module, where the control signal can control the transmission direction and/or angle of the electromagnetic wave of the transmission module.
And the transmitting unit 111 is used for transmitting electromagnetic waves to the energy converging unit according to the direction and/or angle controlled by the transmitting control module. After the transmitting module 11 receives the control signal of the transmitting control module, corresponding actions (such as changing the electromagnetic wave transmitting direction or transmitting angle of the transmitting unit in the transmitting module) are executed according to the control signal, because the control signal is obtained by the transmitting control module 12 based on the position of the device to be charged, after the transmitting unit 111 executes corresponding actions according to the control signal, the energy converging unit 112 converges the electromagnetic wave transmitted by the transmitting unit 111 (such as reflecting convergence or converting the electromagnetic wave transmitted by the transmitting unit into small-angle transmission to converge the electromagnetic wave) to the device to be charged, and the device to be charged is placed at the beam converging point to receive the high-power electromagnetic wave, so that charging can be performed. The device to be charged can be an electronic device with an electromagnetic wave energy receiving antenna, such as an intelligent small household appliance, an intelligent wearable device, an electric toothbrush, an electric shaver, an implantable medical device and the like.
The energy converging unit 112 is configured to converge the received electromagnetic wave transmitted by the transmitting unit into an electromagnetic wave beam to be transmitted to the device to be charged, so as to charge the device to be charged through the electromagnetic wave beam. The energy converging unit 112 is a device (such as an electromagnetic wave reflecting surface or a device capable of converging an electromagnetic wave) capable of converging an electromagnetic wave such that the electromagnetic wave is not or little diffused in a propagation path, and the electromagnetic wave converging manner may be to reflect and converge the electromagnetic wave by using the electromagnetic wave reflecting surface, and the device may be a material capable of reflecting and converging an electromagnetic wave such as a glass surface or a metal surface, and the electromagnetic wave converging manner may be to converge the electromagnetic wave by controlling an emission angle range of the electromagnetic wave so that the electromagnetic wave becomes an electromagnetic narrow beam, thereby achieving an effect of converging the electromagnetic wave. When the energy converging unit converges the electromagnetic wave by reflecting the electromagnetic wave, the emission control module 12 controls the direction and/or angle of the electromagnetic wave emitted by the emission module, and the incident angle of the electromagnetic wave emitted from the emission unit 111 to the energy converging unit 112 changes, so as to change the reflection angle of the electromagnetic wave and reflect the electromagnetic wave to the location of the device to be charged.
The above-mentioned remote wireless power supply unit that this embodiment provided, on the one hand, assembles the electromagnetic wave through the energy unit to promote charging power, on the other hand, through making transmission control module control emission module transmission electromagnetic wave direction and/or angle, can place the optional position of battery charging outfit in the electromagnetic wave emission range and carry out wireless charging, promoted the convenience that wireless charges.
In order to increase the charging power of the remote wireless power supply apparatus, the transmitting module in the remote wireless power supply apparatus provided in this embodiment includes one or more transmitting antennas; the transmitting antenna is used for transmitting electromagnetic waves within a preset angle range. The transmitting antenna can be an electromagnetic wave with a smaller transmitting angle obtained after special treatment, namely, the preset angle range of the electromagnetic wave transmitted by the transmitting antenna is smaller, and when the preset angle range is smaller, the radiation range of the electromagnetic wave can be reduced, so that the charging power is improved.
In a specific embodiment, in order to realize the convergence of the electromagnetic waves, the electromagnetic waves may be converged by using the energy converging unit to reflect the electromagnetic waves, or converged by using the transmitting unit and the energy converging unit as a whole, that is, the transmitting antenna is used as the transmitting module 11, so that the transmitting antenna transmits electromagnetic narrow beams with a smaller angle, thereby achieving the effect of converging the electromagnetic waves. When the electromagnetic wave is converged by using the transmitting antenna as the transmitting module, the transmitting module uses the flat array antenna to transmit the electromagnetic wave with a smaller angle, see the schematic electromagnetic wave transmission diagram shown in fig. 2 and the schematic electromagnetic wave transmission diagram shown in fig. 3, where the preset angle range (transmission angle) of the electromagnetic wave transmitted in fig. 2 is a first preset angle range, and the preset angle range of the electromagnetic wave transmitted in fig. 3 is a second preset angle range, where the second preset angle range is greater than the first preset angle range, as can be seen from fig. 2 and fig. 3, when the transmission angle of the electromagnetic wave transmitted by the transmitting antenna in the transmitting module 11 is increased, the transmitted electromagnetic wave beam is wider and the electromagnetic wave is more dispersed. The emission control module can control the radiation position of the emission antenna according to the position of the device to be charged, so that the electromagnetic waves are emitted to the device to be charged, and therefore the smaller the emission angle (preset angle range) of the emission antenna is, the narrower the beam formed by converging the electromagnetic waves is, and the larger the charging power of the device to be charged is.
In a specific embodiment, the transmission frequency of the transmitting antenna can also be the medium characteristic of air, and the proper transmission frequency is selected to reduce energy attenuation. When the transmitting antenna is a plurality of transmitting antennas, the plurality of transmitting antennas may form an antenna array to improve the transmitting energy density. The distribution positions of the antennas depend on the frequency of electromagnetic waves, the frequency and the phase of the electromagnetic waves in the transmitting antennas are consistent, the directions of the transmitting antennas are uniformly controlled and adjusted by the transmitting control module, and the electromagnetic waves transmitted by the transmitting antennas are converged to the equipment to be charged to receive high-power electromagnetic waves for charging. Correspondingly, the device to be charged can also be provided with a plurality of energy receiving antennas in order to increase the received power.

The device to be charged is provided with a communication module, and the communication module can communicate with a load detector in the remote wireless power supply device. The load detector is used for communicating with a communication module of the equipment to be charged in advance so as to determine the position of the equipment to be charged. The position may also be a relative position of the device to be charged and the remote wireless power supply apparatus, such as the position of the device to be charged is directly in front of the transmitting module of the remote wireless power supply apparatus by a certain distance. The direction controller is used for controlling the electromagnetic wave transmitting directions of the plurality of transmitting antennas to turn to the equipment to be charged according to the relative position between the position of the equipment to be charged and the transmitting antennas, so that the equipment to be charged receives the electromagnetic waves transmitted by the plurality of transmitting antennas through the receiving antennas.

The direction controller is also used for controlling the emission direction of the electromagnetic wave of the emission antenna and simultaneously controlling the emission direction of the light beam of the direction indicating unit. The direction indicating unit is used for emitting a light beam to the energy converging unit in the same emitting direction as the electromagnetic wave when the emitting antenna emits the electromagnetic wave, so that the light beam indicates the beam direction of the electromagnetic wave. The light beam emission direction of the direction indicating unit is the same as the electromagnetic wave emission direction of the transmitting antenna, so that the light beam emitted by the direction indicating unit is the same as the electromagnetic wave emitted by the emitting module to indicate the electromagnetic wave emission direction. The direction indicating unit includes, but is not limited to, a laser, so that a user can find the beam direction of the electromagnetic wave conveniently. The direction indicating unit may further include other visible or invisible light emitters capable of indicating the direction of the electromagnetic wave.

The load detector is further configured to control the direction controller to stop the transmitting antenna from transmitting the electromagnetic wave when the device to be charged is absent in the preset range. When the load detector cannot communicate with the communication module of the device to be charged, it is determined that the device to be charged does not exist within the preset range, and the load detector controls the direction controller to enable the transmitting antenna to stop transmitting electromagnetic waves so as to avoid energy waste.
