When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0022] The vehicle power supply device and vehicle of various embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.
[0023] Figure 1 This application discloses a top view schematic diagram of a vehicle 100 according to one embodiment. Figure 2 A top view schematic diagram of a vehicle 100 according to another embodiment of this application is disclosed. Figure 3 Revealed Figure 2 The diagram shown is a partial three-dimensional side view of vehicle 100. Figure 4 A schematic block diagram of a vehicle 100 according to one embodiment of this application is shown. (See reference...) Figures 1 to 4 As shown, a vehicle 100 according to one embodiment of this application includes a vehicle power supply device 101, which can supply power to external electrical equipment 200 located outside the vehicle 100.
[0024] The vehicle power supply device 101 includes a transmitter module 110 installed inside the vehicle and a receiver module 120 installed outside the vehicle. The transmitter module 110 includes a power transmitting coil 111, and the receiver module 120 includes a power receiving coil 121.
[0025] A power transmitting coil 111 is mounted on the vehicle window to wirelessly transmit electrical energy to a power receiving coil 121. For example, as... Figure 3As shown, in one embodiment of this application, the power transmitting coil 111 can be installed on the inner surface of the glass of the roof 105. Of course, it is understood that the location of the power transmitting coil 111 in this application is not limited to this; it can be installed on a non-metallic material inside the vehicle, such as glass or plastic.
[0026] like Figure 3 As shown, the power receiving coil 121 is used to be installed on the external electrical device 200 to wirelessly receive electrical energy from the power transmitting coil 111, thereby powering the external electrical device 200. In some embodiments, the external electrical device 200 of this application may include a drone cabin installed on the roof 105, with the power receiving coil 121 disposed in the drone cabin. In other embodiments, the external electrical device 200 of this application may include a roof box installed on the roof 105, with the power receiving coil 121 disposed in the roof box. Of course, it is understood that the external electrical device 200 of this application is not limited to a drone cabin or a roof box.
[0027] In some embodiments, the vehicle 100 of this application is provided with a mounting bracket 106 on the roof 105, wherein a drone cabin or a roof box can be mounted on the mounting bracket 106. Thus, the drone cabin or roof box can be detachably mounted on the roof 105 via the mounting bracket 106.
[0028] The vehicle power supply device 101 of this application, by placing a power transmitting coil 111 on the vehicle window and a power receiving coil 121 on the external electrical equipment 200, realizes the wireless transmission of electrical energy from inside the vehicle to the external electrical equipment 200 through near-field wireless coupling of the power transmitting coil 111 and the power receiving coil 121, thereby realizing the power supply of the external electrical equipment 200 and solving the traditional problem of power transmission between the internal and external electrical equipment 200.
[0029] The vehicle power supply device 101 of this application eliminates the need for cable connections by adopting this wireless power supply technology that does not rely on physical connections, thus solving the complexity problem of traditional wired power supply methods and simplifying the power supply process.
[0030] The vehicle power supply device 101 of this application can achieve high-power wireless power supply of, for example, 100 to 300W by employing a power transmitting coil 111 and a power receiving coil 121, to meet the power supply needs of high-power electrical equipment outside the vehicle.
[0031] like Figure 4As shown, the vehicle 100 includes a vehicle infotainment system 103. The transmitting module 110 of this application also includes a first power supply controller 112. The power transmitting coil 111 is electrically connected to the first power supply controller 112; the first power supply controller 112 is communicatively connected to the vehicle infotainment system 103 of the vehicle 100, and the first power supply controller 112 can adjust and control the electrical energy transmitted through the power transmitting coil 111 according to the instructions of the vehicle infotainment system 103.
[0032] In one embodiment, the first power supply controller 112 in the transmitter module 110 can be directly electrically connected to the power supply inside the vehicle.
[0033] In another embodiment, the transmitting module 110 may further include a first power line 113. A first end of the first power line 113 is electrically connected to a first power supply controller 112, and a second end of the first power line 113 has a first connector 114. The first connector 114 can be plugged into the vehicle power supply interface 104. Therefore, the transmitting module 110 can be electrically connected to the vehicle power supply interface 104 in a pluggable manner through the first connector 114.
[0034] The vehicle power supply device 101 of this application configures the transmitting module 110 to be pluggably electrically connected to the in-vehicle power supply interface 104, thereby allowing the device to determine whether to connect the transmitting module 110 to the in-vehicle power supply interface 104 based on the actual power demand of the external electrical device 200. When the external electrical device 200 has no power demand, the first connector 114 of the transmitting module 110 can be disconnected from the in-vehicle power supply interface 104. When the transmitting module 110 is disconnected from the in-vehicle power supply interface 104, the wireless transmission between the power transmitting coil 111 and the power receiving coil 121 is interrupted, and the external electrical device 200 stops working due to the loss of power. When the vehicle 100 starts, the first connector 114 of the transmitting module 110 is plugged into the vehicle power supply interface 104. The transmitting module 110 is activated by the vehicle control system 103. The power transmitting coil 111 converts electrical energy into electromagnetic energy and begins to send electromagnetic waves to the external electrical equipment 200. After receiving the electromagnetic waves, the power receiving coil 121 converts them into electrical energy to supply power to the external electrical equipment 200.
[0035] In one embodiment, the transmitter module 110 can be adhered to the inner surface of the vehicle window using an adhesive. For example, the transmitter module 110 can be adhered to the inner surface of the vehicle window using glue or tape. Optionally, the transmitter module 110 can be designed as a decorative element, so that when the transmitter module 110 is adhered to the inner surface of the vehicle window, the transmitter module 110 itself can also be used as a decorative element to improve its aesthetics.
[0036] In another embodiment, the transmitter module 110 can also be detachably mounted on the inner surface of the vehicle window. For example, a suction cup device (not shown) can be provided on the transmitter module 110. Using the suction force of the suction cup device, the transmitter module 110 can be firmly attached to the inner surface of the vehicle window, thus achieving a detachable connection between the transmitter module 110 and the vehicle window. Therefore, the user can attach the transmitter module 110 to the inner surface of the vehicle window only when the external electrical device 200 needs power, and remove the transmitter module 110 from the window when the external electrical device 200 does not need power, without affecting the window.
[0037] In some embodiments, the power transmitting coil 111 and the power receiving coil 121 can be arranged orthogonally in space. In this case, the vehicle power supply device 101 of this application can achieve efficient coupling by adopting a similar magnetic resonance principle and orthogonal mode, thereby allowing the power transmitting coil 111 and the power receiving coil 121 to be offset within a reasonable range without center alignment, realizing staggered power transmission between the power transmitting coil 111 and the power receiving coil 121, and further improving the reliability of power transmission.
[0038] In some embodiments, the receiving module 120 of this application can be directly integrated into the external electrical equipment 200. The vehicle power supply device 101 can be used in conjunction with the external electrical equipment 200.
[0039] In embodiments where the external electrical equipment 200 includes a drone cabin, the receiving module 120 can be directly integrated into the drone cabin. The drone cabin also includes a second power supply controller 202 and an execution unit 203 for performing opening and closing operations. The power receiving coil 121 is electrically connected to the second power supply controller 202; the second power supply controller 202 is electrically connected to the execution unit 203, and the second power supply controller 202 can control the execution unit 203 to perform the opening and closing operations of the drone cabin.
[0040] Similarly, in embodiments where the external electrical equipment 200 includes a roof box, the receiving module 120 can be directly integrated into the roof box. The roof box includes a second power supply controller 202 and an execution unit 203 for performing opening and closing operations. The power receiving coil 121 is electrically connected to the second power supply controller 202; the second power supply controller 202 is electrically connected to the execution unit 203, and the second power supply controller 202 can control the execution unit 203 to perform the opening and closing operations of the roof box.
[0041] Considering that external electrical devices 200 typically have a power interface 201, to improve the versatility and scalability of the vehicle power supply device 101 of this application, in some embodiments, the receiving module 120 of this application may further include a second power line 123. The first end of the second power line 123 is electrically connected to the power receiving coil 121, and the second end of the second power line 123 has a second connector 124. The second connector 124 can be plugged into the power interface 201 of the external electrical device 200, thereby allowing the receiving module 120 to be electrically connected to the power interface 201 of the external electrical device 200 in a pluggable manner via the second connector 124. Therefore, as long as the external electrical device 200 is equipped with a power interface 201 that matches the second connector 124 of the receiving module 120, the vehicle power supply device 101 of this application can provide power to that external electrical device 200, thus giving the vehicle power supply device 101 wider applicability and enabling it to power various external electrical devices 200.
[0042] The vehicle power supply device 101 and vehicle 100 of this application greatly simplify the power connection of internal and external equipment through near-field wireless power supply technology, avoiding the complexity and unsightly problems of traditional cable connection.
[0043] The vehicle power supply device 101 and vehicle 100 of this application can achieve high power transmission, support high power supply of 100-300W, meet the needs of high power equipment, and have broad application prospects.
[0044] The vehicle power supply device 101 and vehicle 100 of this application eliminate the use of cables by transmitting power wirelessly, which not only improves the ease of use of the device, but also reduces the safety hazards of cable damage and overheating.
[0045] The vehicle power supply device 101 and vehicle 100 of this application are highly adaptable and can be applied to a variety of external electrical equipment 200, thus having a wide range of applicability.
