In one aspect, as shown in fig. 1 and 2, the present embodiment provides a vehicle-mounted charging system 100, where the vehicle-mounted charging system 100 is adapted to perform space-apart charging on a terminal device 200 in an in-vehicle space 300.

The in-vehicle charging system 100 includes: a charge control module 1 and an execution module 2; the charging control module 1 is configured to determine power information of the vehicle power supply 400, number information of the terminal devices 200, and power information of the terminal devices 200; the charging control module 1 is electrically connected to the execution module 2, and the charging control module 1 is configured to send a charging instruction to the execution module 2 when the electric quantity of the vehicle power supply 400 is higher than a first set value, the number of the terminal devices 200 is greater than or equal to 1, and the electric quantity of the terminal devices 200 is lower than a second set value.

The execution module 2 includes an electric energy transmitting end 21 and an electric energy receiving end 22, the electric energy transmitting end 21 is electrically connected with the vehicle power supply 400, the electric energy receiving end 22 is electrically connected with the terminal device 200, and the execution module 2 is configured to perform spaced charging on the terminal device 200 through the electric energy transmitting end 21 and the electric energy receiving end 22 after receiving the charging instruction.

The vehicle-mounted charging system 100 is arranged in a vehicle and can be used for carrying out spaced charging on the terminal equipment 200 in the vehicle interior space 300, and comprises a charging control module 1 and an execution module 2, wherein the charging control module 1 is used for determining electric quantity information of a vehicle power supply 400, quantity information of the terminal equipment 200 and electric quantity information thereof, when the electric quantity of the vehicle power supply 400 is enough, the quantity of the terminal equipment 200 is greater than or equal to 1, and the electric quantity of the terminal equipment 200 is in a state of being required to be charged, the execution module 2 is started, an electric energy transmitting end 21 of the execution module 2 is used for acquiring electric energy from the vehicle power supply 400, the electric energy transmitting end 21 and an electric energy receiving end 22 are coupled in a spaced manner, and the electric energy receiving end 22 is used for transmitting the electric energy to the terminal equipment 200 by utilizing the working principles of electricity generation and magnetism generation, so that the spaced charging of the terminal equipment 200 is completed, the terminal equipment 200 in any position and in a using state can be carried out non-contact charging on the terminal equipment 200 in the vehicle interior space 300, and the terminal equipment 200 in any using state can be simultaneously charged, the convenience and the rapidness of the charging of the vehicle interior space 300 to greatly improve the charging of the terminal equipment 200 and the user experience.

The in-vehicle space 300 in the present embodiment refers to an interior space of a vehicle, which includes, but is not limited to, a passenger compartment, a cargo compartment, a trunk, and an engine compartment. Any spatial region in which the terminal device 200 powered by the battery needs to be disposed can be regarded as the in-vehicle space 300 of the present embodiment.

In this embodiment, the power transmitting terminal 21 and the power receiving terminal 22 implement spaced transmission of power by using an infinite radio frequency technology. In operation, the power transmitting terminal 21 converts power into a radio frequency signal with a certain frequency, and when the power receiving terminal 22 enters the operating area of the power transmitting terminal 21, an induced current is generated, and the induced current is used to store the power in the terminal device 200.

In some possible implementations, the power transmitting end 21 may only transmit the radio frequency signal in a specific direction, that is, in the direction in which the terminal device 200 to be charged is located, so as to increase the strength of the radio frequency signal received by the power receiving end 22, and the power receiving end 22 may output a larger induced current, thereby increasing the power of the spaced charging.

As another example, the power transmitting terminal 21 may simultaneously transmit radio frequency signals to a plurality of specific directions, thereby realizing the spaced charging of the terminal devices 200 at a plurality of different locations.

The radio frequency signal transmitting direction of the power transmitting end 21 may be fixed, for example, the radio frequency signal transmitting direction is directed to the position of the steering wheel, so that the terminal device 200 placed in front of the driver can be charged at intervals. For another example, when the emission direction of the radio frequency signal is directed to the space above the front passenger seat and the passenger of the front passenger seat holds the terminal device 200, the terminal device 200 may just be located in the emission direction of the radio frequency signal, and similarly, the emission direction of the radio frequency signal is directed to the upper side of the rear seat, so that the handheld terminal device 200 of the passenger of the rear seat may be charged at intervals. For another example, the transmitting direction of the radio frequency signal refers to the area where the rearview mirror is located in the vehicle, and auxiliary equipment such as a vehicle recorder and the like which are added or built in the rearview mirror can be charged in a spaced mode.

Alternatively, the radio frequency signal emission direction of the power emission terminal 21 may be configured and selected at the charge control module 1, for example, to emit radio frequency signals only toward the upper side of the passenger seat, or to emit radio frequency signals toward both the passenger seat and the rearview mirror area.

Alternatively, the power transmitting end 21 includes a directional transmitting antenna (Directional antenna). A directional transmitting antenna refers to an antenna that emits electromagnetic waves particularly strongly in one or more specific directions, while emitting electromagnetic waves in other directions is zero or very small. The adoption of the directional transmitting antenna can increase the effective utilization rate of the radiation power and enhance the signal strength.

Alternatively, the power transmitting end 21 includes a phased array antenna (PHASED ARRAY ANTENNA), and the directional pattern beam pointing can be changed by controlling the feeding phase of the radiating elements in the array antenna so that the beam is always pointed at the power receiving end 22, and the beam pointing adjustment can be performed according to the position adjustment of the power receiving end 22.

In some possible implementations, the vehicle power supply 400 is a vehicle battery. The first set value is 40% -70%. For example, if the first set value is 50%, the charging control module 1 will start the space charging of the terminal device 200 only when the electric quantity of the vehicle power supply 400 is higher than 50%, otherwise will not start, preventing the electric quantity of the vehicle power supply 400 from being too low, affecting the normal start of the vehicle, or the normal use of other necessary devices of the vehicle (such as a lamp system, a vehicle machine system, etc.).

In some embodiments, the power receiving end 22 is located in the terminal device 200 or is electrically connected to a charging interface of the terminal device 200. The power receiving terminal 22 in this embodiment may have various forms, and may be integrated inside the terminal device 200 or designed integrally with other antennas of the terminal device 200. The power receiving end 22 can be designed as a small and light accessory, and is plugged into the charging interface of the terminal device 200, so that the normal use of the terminal device 200 is not affected.

The charging control module 1 is in telecommunication connection with the vehicle body controller 500, so that the electric quantity of the vehicle power supply 400 can be directly obtained from the vehicle body controller 500, the charging control module 1 does not need to automatically measure, the working efficiency of the charging control module 1 is improved, and the system integration of the vehicle is improved.

KL15 is also called a cut-off power supply, and is connected to the ignition switch, and only when the ignition switch is turned on, the power is turned on. Thus, in the first charging mode, the vehicle can charge the terminal device 200 with a space without turning on the ignition switch (or key switch); in the second charging mode, the vehicle needs to charge the terminal device 200 with a space between them with the ignition switch (or key switch) turned on.
