[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] See also Figure 1 , Figure 1 Schematic diagram of an application scenario of a charging method for a mobile terminal device in a vehicle provided by an embodiment of the present application. Figure 1 As shown, the application scenario includes a vehicle 101 and a device to be charged 102 ( Figure 1In the figure, the device to be charged is a mobile phone as an example, wherein the vehicle 101 and the device to be charged 102 communicate with each other through a network. An energy transceiver is provided in the vehicle 101, and the energy transceiver includes a transmitter and a receiver.

[0049] Among them, the vehicle 101 can control the transmitter to transmit multiple positioning beams to the preset charging area, and receive multiple positioning beam feedback signals fed back by the device to be charged 102 in the preset charging area through the receiver; the preset charging area is a part of the area inside the vehicle; based on the multiple positioning beam feedback signals, determine the position of the receiving antenna array of the device to be charged 102; based on the position of the receiving antenna array and the position of the transmitting antenna array of the transmitter, determine the energy transmission direction; control the transmitter to transmit a radio frequency beam in the energy transmission direction, and the radio frequency beam is used to charge the device to be charged 102. In this way, when the energy transmission direction is determined based on the position of the receiving antenna array of the device to be charged 102 and the position of the transmitting antenna array of the transmitter, the vehicle 101 can control the transmitter to transmit the radio frequency beam to the position of the receiving antenna array of the device to be charged 102 along the energy transmission direction, so that as many radio frequency beams as possible output by the transmitter are transmitted to the receiving antenna array of the device to be charged 102, which is conducive to reducing the output range of the radio frequency beam and improving the accuracy of the output range of the radio frequency beam, so as to avoid the radio frequency beam from being transmitted to the area where the device to be charged is not located, thereby reducing energy waste.

[0050] Optionally, the device to be charged 102 may be a mobile terminal device, and the mobile terminal device mentioned here may include but is not limited to: a smart phone, a tablet computer, a laptop computer, a smart watch, etc.

[0051] The following is a detailed description of the charging method for a mobile terminal device in a vehicle provided in an embodiment of the present application.

[0052] See also Figure 2 , Figure 2 1 is a flow chart of a method for charging a mobile terminal device in a vehicle provided by an embodiment of the present application. The method can be performed by a vehicle (e.g. Figure 1 The vehicle 101 in FIG. Figure 2 As shown, the charging method of the mobile terminal device in the vehicle may include but is not limited to the following steps:

[0053] S201, controlling a transmitter to transmit a plurality of positioning beams to a preset charging area, and receiving, through a receiver, a plurality of positioning beam feedback signals fed back by a device to be charged in the preset charging area.

[0054] Among them, the preset charging area is a part of the area inside the vehicle.

[0055] The transmitter includes an energy source and a transmitting antenna array. The energy source can be used to connect to the vehicle power supply, and the transmitting antenna array can be used to convert electrical energy into millimeter waves and transmit them.

[0056] The receiver includes a receive antenna array, which is used to capture some feedback beams.

[0057] Optionally, the transmitting antenna array is a high-efficiency antenna array capable of transmitting millimeter waves, and the receiving antenna array is a high-efficiency antenna array capable of receiving millimeter waves. These antenna arrays can dynamically adjust the beam direction in three-dimensional space. Among them, millimeter waves refer to electromagnetic waves with a wavelength of 1 to 10 mm. Millimeter waves have the characteristics of large bandwidth, high rate and low latency, and have high directivity and focusing capabilities. Their disadvantages are short transmission distance and great influence by obstacles. However, since the space distance in the vehicle cabin is not large and there are few obstructions, millimeter wave technology can be used to realize wireless charging of mobile terminal devices in the vehicle.

[0058] For example, see Figure 3 , Figure 3 Schematic diagram of a beam transmission provided by an embodiment of the present application. Figure 3 As shown, the vehicle includes a transceiver 301 and a device to be charged 302, and the transceiver 301 includes a transmitter 3011 and a receiver 3012. The vehicle controls the transmitter 3011 to transmit multiple positioning beams to the preset charging area, that is, Figure 3 The vehicle also receives multiple positioning beam feedback signals emitted by the device to be charged through the receiver 3012, namely Figure 3 It should be noted that the positioning beam feedback signal transmitted by the device to be charged 302 is a feedback signal transmitted based on the positioning beam received by the receiving antenna array of the device to be charged 302. Therefore, Figure 3 In the figure, it is shown as an example that the number of positioning beams (solid line beams) received by the receiving antenna array of the device to be charged 302 is 5, and the number of corresponding positioning beam feedback signals (dashed line beams) sent is also 3.

[0059] The present application executes step 201 to control the transmitter 3011 to transmit a larger number of positioning beams in a larger range to one side of the device to be charged 302, thereby avoiding the situation where some areas of the receiving antenna array in the device to be charged 302 cannot receive the positioning beam and thus cannot feed back the corresponding positioning beam feedback signal. This is beneficial to improving the precise positioning of the position of the receiving antenna array in the device to be charged 302 based on the positioning beam emitted by the transmitter 3011.

[0060] It should be noted that the present application does not specifically limit the number of preset charging areas in the vehicle. For example, if the number of preset charging areas in the vehicle is 4, then by executing step 201, the positioning beam can be sent to the 4 preset charging areas in the vehicle at the same time, but it is also possible to choose to send the positioning beam to only one or two of the preset charging areas at a time; in addition, the present application does not limit the number of devices to be charged included in one preset charging area. For example, multiple devices to be charged in one preset charging area can be charged wirelessly at the same time, or multiple devices to be charged in multiple preset charging areas can be charged wirelessly at the same time.

[0061] S202: Determine the position of the receiving antenna array of the device to be charged based on multiple positioning beam feedback signals.

[0062] Among them, the receiving antenna array of the device to be charged is a high-efficiency antenna array capable of receiving millimeter waves.

[0063] In the case where the vehicle receives multiple positioning beam feedback signals transmitted by the device to be charged 302 based on the execution of step 201, step 202 may be further executed so that the vehicle can determine the position of the receiving antenna array of the corresponding device to be charged based on the received multiple positioning beam feedback signals. Specifically, the signal strength and phase information of each positioning beam feedback signal in the multiple positioning beam feedback signals may be determined based on the received positioning beam feedback signal; the position of the receiving antenna array of the device to be charged may be determined based on the signal strength and phase information of each positioning beam feedback signal, so that the vehicle can learn the specific spatial position information of the device to be charged that needs to be charged wirelessly relative to the charging signal transmitting end (transceiver 301).

[0064] S203: Determine the energy transmission direction based on the position of the receiving antenna array of the device to be charged and the position of the transmitting antenna array of the transmitter.

[0065] It should be noted that the position of the transceiver 301 in the vehicle is fixed, so the position of the transmitter 3011 included therein is also fixed; therefore, when executing step 203 to obtain the specific position information of the device to be charged relative to the transceiver 301, the vehicle can determine the energy transmission direction between the receiving antenna array of the device to be charged and the transmitting antenna array of the transmitter based on the position of the receiving antenna array of the device to be charged and the position of the transmitting antenna array of the transmitter, thereby facilitating the subsequent accurate charging of the corresponding device to be charged 302 through the transceiver 301. Specifically, the position of the transmitting antenna array of the transmitter is taken as the starting point, and the direction from the starting point to the position of the receiving antenna array of the device to be charged is determined as the energy transmission direction.

[0066] S204, controlling the transmitter to transmit a radio frequency beam in the direction of energy transmission, where the radio frequency beam is used to perform wireless charging on the device to be charged.

[0067] Specifically, when executing step 203 to obtain the energy transmission direction between the receiving antenna array of the device to be charged and the transmitting antenna array of the transmitter, step 204 can be further executed to control the transmitter to transmit a radio frequency beam to the corresponding device to be charged along the determined energy transmission direction, so as to realize wireless charging of the corresponding device to be charged through the radio frequency beam, thereby facilitating the user to charge the device to be charged at any location in the vehicle, improving the convenience of the charging process, and helping to improve the vehicle experience of users in the vehicle.

[0068] Optionally, the RF beam may be a millimeter wave beam.

[0069] In an optional embodiment, the vehicle controls the transmitter to transmit a radio frequency beam in the direction of energy transmission, which may include: transmitting a control signal to the transmitter, wherein the control signal is used to instruct the transmitter to transmit the radio frequency beam in the direction of energy transmission; the transmitter responds to the control signal and transmits the radio frequency beam in the direction of energy transmission.

[0070] In an embodiment of the present application, the vehicle can control the transmitter to transmit multiple positioning beams to a preset charging area, and receive multiple positioning beam feedback signals fed back by the device to be charged in the preset charging area through the receiver; determine the position of the receiving antenna array of the device to be charged based on the multiple positioning beam feedback signals; determine the energy transmission direction based on the position of the receiving antenna array and the position of the transmitting antenna array of the transmitter; control the transmitter to transmit a radio frequency beam in the energy transmission direction, and the radio frequency beam is used to perform wireless charging on the device to be charged. Using this method, the vehicle can control the transmitter to transmit a radio frequency beam in the energy transmission direction determined based on the position of the receiving antenna array of the device to be charged and the position of the transmitting antenna array of the transmitter, thereby reducing the output range of the radio frequency beam to avoid the radio frequency beam from being transmitted to areas where the device to be charged is not located, thereby reducing energy waste.

[0071] In addition, in the embodiment of the present application, since the direction of energy transmission is determined by adjusting the direction of the transmitting antenna array of the transmitter based on the position of the receiving antenna array of the device to be charged, and the radio frequency beam is emitted in the direction of energy transmission, no matter where the passengers in the vehicle move the device to be charged, the device to be charged can be charged. In other words, the method provided by the present application can support wireless charging of the device to be charged at any position in the vehicle, so that there will be no interference with the use of the device to be charged during the charging process, and the device to be charged can be used while charging, that is, the flexibility of charging mobile terminal devices in the vehicle is improved.

[0072] Therefore, the method for charging a mobile terminal device in a vehicle provided by the present application can support wireless charging of the mobile terminal device at any position within the interior space of the vehicle, so that the use of mobile phones or other mobile electronic devices will not be interfered with during the charging process, and the use of mobile terminals such as mobile phones will not be affected while charging, so that the mobile phone can be used while charging. The use of this method not only greatly improves the convenience of the charging process, but also significantly improves the overall user experience of passengers in the vehicle.

[0073] See also Figure 4 , Figure 4 1 is a flow chart of another method for charging a mobile terminal device in a vehicle provided by an embodiment of the present application. Figure 2 The method for charging a mobile terminal device in a vehicle shown differs in that: Figure 4 The method shown also describes that the vehicle dynamically adjusts the voltage of the transmitter in the direction of energy transmission. Figure 4 As shown, the charging method of the mobile terminal device in the vehicle may include but is not limited to the following steps:

[0074] S401, controlling a transmitter to transmit a plurality of positioning beams to a preset charging area, and receiving, through a receiver, a plurality of positioning beam feedback signals fed back by a device to be charged in the preset charging area.

[0075] In an optional implementation, before step S401, the vehicle may also determine a preset charging area from a plurality of pre-planned in-vehicle areas in response to the area setting operation of the client. This is beneficial for subsequent vehicles to control the transmitter to transmit positioning beams or radio frequency beams only to the preset charging area selected by the user, and not to transmit positioning beams or radio frequency beams to the preset charging area not selected by the user, thereby improving the efficiency and accuracy of radio frequency beam transmission, and further, reducing energy waste.

[0076] For example, see Figure 5 , Figure 5 Schematic diagram of the interior of a vehicle cabin provided in an embodiment of the present application. Figure 5 As shown in the figure, the vehicle cabin includes the driver area, the co-pilot area and the rear passenger area. The user can designate the right side of the co-pilot area and the rear passenger area as the commonly used charging area (i.e. Figure 5 The left side of the passenger area and rear passenger area is the unused charging area (i.e. Figure 5After that, the user may input a user operation in the user interface of the vehicle, the user operation being used to designate the preset charging areas in the vehicle as charging area 1 and charging area 2, and the preset non-charging areas as non-charging area 1 and non-charging area 2, wherein the user interface displays the information inside the vehicle cabin. In this case, the vehicle may determine the preset charging area and the preset non-charging area in the vehicle in response to the above user operation. Among them, charging area 1 and charging area 2 are the areas where the receiving antenna arrays of the device to be charged are located.

[0077] like Figure 5 As shown, the vehicle cabin also includes a transmitter. The transmitter is a transmitter based on millimeter wave transmission technology, and the transmitter is set in the middle of the vehicle cabin to transmit beams to charging area 1, charging area 2, non-charging area 1 and non-charging area 2 at the same time as much as possible, and reduce the obstruction of obstacles.

[0078] Optionally, the vehicle can also detect an adjustment operation for a preset charging area and a preset non-charging area; in response to the adjustment operation, determine an adjusted preset charging area and an adjusted preset non-charging area; wherein the adjustment operation can be determined by the user based on the number of passengers in the vehicle.

[0079] In another optional embodiment, before step S401, the user device may detect a startup operation for an application associated with the vehicle, start the application associated with the vehicle, and display a target user interface; detect a user operation for the target user interface, which is used to specify a preset charging area in the vehicle; and determine the preset charging area in response to the user operation.

[0080] S402: Determine the position of the receiving antenna array of the device to be charged based on multiple positioning beam feedback signals.

[0081] Among them, the receiving antenna array of the device to be charged is a high-efficiency antenna array capable of receiving millimeter waves.

[0082] Optionally, the vehicle may analyze multiple positioning beam feedback signals through a central processor to determine the location of a receiving antenna array of the device to be charged.

[0083] In an optional embodiment, the vehicle can also periodically control the transmitter to transmit multiple positioning beams to the preset charging area to track the position of the receiving antenna array based on the positioning beam feedback mechanism; based on the tracked position of the receiving antenna array, the direction of energy transmission is adjusted. In other words, the vehicle can update the position of the receiving antenna array of the device to be charged relative to the transceiver based on the positioning beam feedback signal received in real time. This helps the vehicle to adjust the direction of energy transmission in real time according to the updated position of the receiving antenna array, so that no matter which area of ​​the vehicle the device to be charged moves to, it can transmit a radio frequency beam in the adjusted energy transmission direction to achieve continuous charging of the device to be charged, that is, to improve the flexibility of charging mobile terminal devices in the vehicle.

[0084] S403: Determine the energy transmission direction based on the position of the receiving antenna array of the device to be charged and the position of the transmitting antenna array of the transmitter.

[0085] In an optional implementation, the relevant description of step S403 can refer to the description of the aforementioned step S202, which will not be repeated here.

[0086] S404: Periodically obtain the remaining power and temperature of the device to be charged.

[0087] S405. Based on the remaining power and temperature of the device to be charged, dynamically adjust the voltage of the transmitter in the energy transmission direction, so that the voltage decreases as the remaining power of the device to be charged increases, and decreases as the temperature of the device to be charged increases.

[0088] In an optional embodiment, the target charging power is determined by the user based on the type of device to be charged and a safety assessment; the target charging power can be a low-range charging power (e.g., 5 watts), a mid-range charging power (e.g., 10 watts), or a high-range charging power (e.g., 20 watts).

[0089] In an optional embodiment, the vehicle dynamically adjusts the voltage of the transmitter in the energy transmission direction based on the remaining power and temperature of the device to be charged, so that the voltage decreases as the remaining power of the device to be charged increases, and decreases as the temperature of the device to be charged increases, which may include: when it is determined that the remaining power of the device to be charged is in a preset low power range, and / or the temperature of the device to be charged is in a preset low temperature range, adjusting the voltage of the transmitter in the energy transmission direction to a preset high voltage; when it is determined that the remaining power of the device to be charged is in a preset medium power range, and / or the temperature of the device to be charged is in a preset medium temperature range, adjusting the voltage of the transmitter in the energy transmission direction to a preset medium voltage; when it is determined that the remaining power of the device to be charged is in a preset high power range, and / or the temperature of the device to be charged is in a preset high temperature range, adjusting the voltage of the transmitter in the energy transmission direction to a preset low voltage; when it is determined that the device to be charged has completed charging, and / or the temperature of the device to be charged is greater than a preset high temperature threshold, controlling the transmitter to stop transmitting the radio frequency beam in the energy transmission direction.

[0090] In this embodiment, the high voltage is the voltage corresponding to the preset high-level charging power (for example, 20 watts), the medium voltage is the voltage corresponding to the preset medium-level charging power (for example, 10 watts), and the low voltage is the voltage corresponding to the preset low-level charging power (for example, 5 watts). The preset charging powers of each level are determined by the user based on the type of the device to be charged and the safety assessment.

[0091] Exemplarily, assuming that the preset low power interval is [0, 20%], and the remaining power of the device to be charged is 18%, the vehicle can determine that the remaining power of the device to be charged is 18% in the preset low power interval. In this case, the vehicle can adjust the voltage of the transmitter in the energy transmission direction to a high voltage to switch to a high-speed charging power. Alternatively, assuming that the preset low temperature interval is [0, 20°C], and the temperature of the device to be charged is 17°C, the vehicle can determine that the temperature of the device to be charged is in the preset low temperature interval. In this case, the vehicle can adjust the voltage of the transmitter in the energy transmission direction to a high voltage to switch to a high-speed charging power. Alternatively, assuming that the preset low power interval is [0, 20%], the remaining power of the device to be charged is 18%, the preset low temperature interval is [0, 20°C], and the temperature of the device to be charged is 17°C, the vehicle can determine that the remaining power of the device to be charged is 18% in the preset low power interval, and determine that the temperature of the device to be charged is 17°C in the preset low temperature interval. In this case, the vehicle can adjust the voltage of the transmitter from a low voltage to a high voltage to switch to a high-speed charging power.

[0092] In an optional implementation, the vehicle may also periodically obtain the remaining battery power of the vehicle; and when it is determined that the remaining battery power of the vehicle is less than a preset vehicle battery power threshold, the transmitter is turned off.

[0093] In this embodiment, the vehicle can also adjust the voltage of the transmitter in the energy transmission direction to a medium voltage when it is determined that the remaining power of the vehicle is within a preset power range.

[0094] S406. Based on millimeter wave technology, convert the adjusted transmitter voltage into a radio frequency beam of a corresponding millimeter wave frequency.

[0095] Millimeter wave technology refers to the use of millimeter waves as a way of energy transmission. Energy transmission refers to the use of millimeter wave technology to convert electrical energy into electromagnetic waves of millimeter wave frequency for transmission, where electromagnetic waves can be used to transfer energy between transmitters and receivers.

[0096] It is understandable that if the voltage of the transmitter is different, the frequency of the RF beam of the millimeter wave frequency converted based on the millimeter wave technology will be different.

[0097] S407. Control the transmitter to transmit a radio frequency beam in the direction of energy transmission, where the radio frequency beam is used to perform wireless charging on the device to be charged.

[0098] In an optional implementation, after step S406, the vehicle may also stop sending the radio frequency beam in the energy transmission direction when it is determined that the device to be charged has completed charging, thereby further reducing energy waste.

[0099] In an embodiment of the present application, on the one hand, the vehicle can control the transmitter to transmit multiple positioning beams to a preset charging area, and receive multiple positioning beam feedback signals fed back by the device to be charged in the preset charging area through the receiver; based on the multiple positioning beam feedback signals, determine the position of the receiving antenna array of the device to be charged; based on the position of the receiving antenna array and the position of the transmitting antenna array of the transmitter, determine the energy transmission direction, which is beneficial for the vehicle to control the transmitter to transmit the radio frequency beam in the energy transmission direction determined based on the position of the receiving antenna array of the device to be charged and the position of the transmitting antenna array of the transmitter, thereby reducing the output range of the radio frequency beam, avoiding the radio frequency beam from being transmitted to areas where the device to be charged is not located, and thus reducing energy waste. On the other hand, the vehicle also dynamically adjusts the voltage of the transmitter in the energy transmission direction based on the remaining power and temperature of the device to be charged, so that the voltage decreases as the remaining power of the device to be charged increases, and as the temperature of the device to be charged increases; based on millimeter wave technology, the adjusted transmitter voltage is converted into a corresponding radio frequency beam of millimeter wave frequency; the transmitter is controlled to transmit a radio frequency beam in the energy transmission direction, and the radio frequency beam is used to perform wireless charging on the device to be charged. In this way, the vehicle dynamically adjusts the voltage of the transmitter based on the remaining power and temperature of the device to be charged, and controls the transmitter to transmit a radio frequency beam of millimeter wave frequency obtained by converting the adjusted transmitter voltage in the energy transmission direction, so that the vehicle controls the transmitter to transmit a radio frequency beam of the target millimeter wave frequency, thereby facilitating the dynamic allocation of energy in the scenario where multiple devices to be charged need to be charged at the same time, so as to efficiently charge multiple devices to be charged at the same time. In addition, by using the embodiment of the present application, in the process of charging the device to be charged, it is not necessary to insert the device to be charged into the charging port or place it in a specific position, thereby improving the convenience of charging the mobile terminal device in the vehicle.

[0100] In addition, by using the embodiments of the present application, it is possible to simultaneously support charging of a variety of different devices to be charged (such as mobile phones, tablets, etc.), thereby improving the compatibility and scalability of charging mobile terminal devices in the vehicle.

[0101] In an optional embodiment, the vehicle is executing Figure 2 or Figure 4 Before the charging method of the mobile terminal device in the vehicle shown, first confirmation information and second confirmation information can also be detected, the first confirmation information is used to indicate that the safety assessment result for the vehicle is passed, and the second confirmation information is used to indicate that the compliance certification result for the vehicle is passed.

[0102] In this embodiment, the first confirmation information can be manually detected by electromagnetic radiation in the vehicle, and input when it is determined that the detection result meets the safety standards; the second confirmation information can be manually detected by radio communication in the vehicle, and input when the detection result meets the vehicle and radio communication standards.

[0103] Optionally, the compliance certification is, for example, compliance with the Federal Communications Commission (FCC) certification or the European Conformity (CE) certification.

[0104] In an embodiment of the present application, the vehicle may execute the step of charging the mobile terminal device in the vehicle after detecting the first confirmation information and the second confirmation information, thereby improving the safety of charging the mobile terminal device in the vehicle.
