[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by 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.

[0021] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0022] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Figure 1 A schematic diagram of a wireless charging parking space provided by an embodiment of the present application is shown. For ease of description, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0025] The wireless charging parking space 10 includes: a wireless charger 100 embedded in the ground, and the wireless charger 100 includes a plurality of wireless charging modules. Figure 1 As shown, exemplarily, in one embodiment, the multiple wireless charging modules of the wireless charger 100 include a wireless charging module 110a, a wireless charging module 110b, a wireless charging module 110c and a wireless charging module 110d.

[0026] Among them, at least one wireless charging module is used to charge the target vehicle on the ground with a first power, and at least one wireless charging module is used to charge the target vehicle on the ground with a second power, and the first power is not equal to the second power. For example, the wireless charging module 110a can be used to output the first power, and the wireless charging module 110b can be used to output the second power. The target vehicle can specifically be an electric vehicle.

[0027] By arranging a plurality of wireless charging modules that can output different powers on the first wireless charging parking space 10, the compatibility of the wireless charging parking space 10 can be improved to meet the wireless charging requirements of target vehicles of different models.

[0028] It can be understood that at least one of the multiple wireless charging modules can be used to charge the target vehicle with other powers that are not equal to the first power and the second power. The signal and the number of output powers of the wireless charging module can be set according to actual needs, and the embodiments of the present application do not limit it.

[0029] For example, the wireless charging module 110c can output the third power, and the wireless charging module 110d can output the fourth power. The model and output of the wireless charging module can be set according to actual needs, and the embodiment of the present application does not limit it.

[0030] In one embodiment, if Figure 2 As shown, the wireless charger 100 includes a plurality of first wireless charging modules and a plurality of second wireless charging modules, the first wireless charging modules are used to charge the target vehicle with a first power, and the second wireless charging modules are used to charge the target vehicle with a second power. Figure 2 A first wireless charging module 111a - 111c and a second wireless charging module 112a - 112c are shown.

[0031] The first wireless charging modules and the second wireless charging modules are alternately arranged in sequence along a first direction of the ground.

[0032] It should be noted that since the parking position of each target vehicle in the wireless charging parking space 10 is relatively random, and the installation positions of the modules for wireless charging of target vehicles of different models are also different, by setting multiple first wireless charging modules and multiple second wireless charging modules, and by spacing the first wireless charging module and the second wireless charging module along the first direction of the ground, the coverage area of ​​each wireless charging module can be increased, and each wireless charging module can be evenly distributed in the wireless charging parking space 10 to ensure that the target vehicle can be charged normally.

[0033] In some embodiments, the wireless charger 100 further includes other wireless charging modules for charging at other powers different from the first power and the second power. For example, the wireless charger 100 may further include a third wireless charging module and a fourth wireless charging module for charging at a third power and a fourth power. The model of the wireless charging module can be set according to actual needs, and the embodiments of the present application do not limit it.

[0034] In one embodiment, the first wireless charging module and the second wireless charging module are both in a long rectangular structure and extend along a second direction parallel to the ground. The second direction may be perpendicular to the first direction.

[0035] It can be understood that by configuring the first wireless charging module and the second wireless charging module to be long rectangular structures, the coverage area of ​​a single wireless charging module can be expanded as much as possible, thereby increasing the probability that the target vehicle can be charged normally.

[0036] In one embodiment, the second direction intersects with any side line of the planning line 200 of the wireless charging parking space 10 .

[0037] It is understandable that the wireless charging parking space 10 is usually rectangular, and the second direction intersecting with any side line of the planning line 200 of the wireless charging parking space 10 means that the first wireless charging module and the second wireless charging module are both arranged obliquely in the wireless charging parking space 10.

[0038] Exemplarily, the second direction may be parallel to one of the diagonal lines of the planning line 200 of the wireless charging parking space 10 .

[0039] It can be understood that the wireless charging module located in the middle can be set to be longer to cover a larger area. At the same time, the wireless charging module located in the middle is also the main wireless charging module used for wireless charging, which can increase the overlapping area between the wireless charging module located in the middle and the wireless charging module of the target vehicle, thereby increasing the probability of the wireless charging module successfully charging the target vehicle.

[0040] In one embodiment, each wireless charging module is buried under the ground of the wireless charging parking space 10 . Exemplarily, the first wireless charging module and the second wireless charging module are buried under the ground of the wireless charging parking space 10 .

[0041] Burying the wireless charging module below the ground of the wireless charging parking space 10 can prevent the wireless charging module from directly contacting the outside world, thereby reducing the probability of damage to the wireless charging module.

[0042] It is understandable that whether the wireless charging module is buried under the ground is determined by the wireless charging module, and when the structural strength of the wireless charging module meets the requirements, the wireless charging module can also be set on the ground. The embodiments of the present application do not limit this.

[0043] In one embodiment, the first power is greater than the second power, and the burial depth of the first wireless charging module is greater than the burial depth of the second wireless charging module.

[0044] It is understandable that the buried depth of the wireless charging module also needs to be set according to the output power of the wireless charging module. The greater the output power, the deeper the buried depth of the wireless charging module can be. The buried depth can change the upper and lower limits of the power transmission of the wireless charging module to improve the charging compatibility of the wireless charging parking space 10.

[0045] Figure 3 A schematic diagram of a parking lot provided by an embodiment of the present application is shown. For the sake of convenience, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0046] The parking lot 20 includes a plurality of wireless charging parking spaces as in any of the above embodiments. Figure 3 The parking lot 20 includes wireless charging parking spaces 10a to 10d.

[0047] In one embodiment, if Figure 4 As shown, the parking lot 20 further includes an electric energy conversion device 40 and a control device 30, the electric energy conversion device 40 is connected to the control device 30, the wireless charging module 110 of the wireless charging parking space 10 includes a radio frequency unit 120 and a charging coil 130, the radio frequency unit 120 is connected to the control device 30, and the charging coil 130 is connected to the electric energy conversion device 40. Among them, the control device 30 may include control devices such as a single-chip microcomputer and an industrial computer.

[0048] The RF unit 120 can send or receive RF signals for wireless communication with the target vehicle to obtain the charging parameters of the target vehicle. For example, the charging parameters such as the charging power and battery model of the vehicle can be obtained, and the charging parameters can be fed back to the control device 30. The control device 30 is used to control the power conversion device 40 according to the charging parameters to charge the target vehicle through the charging coil 130 of the wireless charging module 110 corresponding to the charging parameters.

[0049] Exemplarily, the radio frequency unit 120 may include at least one of a Wifi transmitter and a Bluetooth transmitter.

[0050] The control device 30 can control the power conversion device 40 to realize the direct current-alternating current (DC-AC) conversion function, and the control device 30 can control the power conversion device 40 to realize the alternating current-alternating current (AC-AC) conversion function. At the same time, the control device 30 can also control the power conversion device 40 to perform voltage conversion according to the charging parameters to provide corresponding voltage and power.

[0051] The wireless charging module 110 of each wireless charging parking space 10 may be connected to the power conversion device 40 and the control device 30 to charge the target vehicle after acquiring electric energy from the power conversion device 40 under the control of the control device 30 .

[0052] In some embodiments, the parking lot 20 also includes a communication unit, which is connected to the control device 30. The communication unit is used to connect to the corresponding server through the network to upload the operation data of the parking lot 20. It can also query the charging parameters of the target vehicle and battery when the radio frequency unit 120 only obtains the model and battery model of the target vehicle.

[0053] In one embodiment, the parking lot 20 further includes a power generation device 50 , which is connected to the electric energy conversion device 40 , and is used to provide electric energy for charging to the electric energy conversion device 40 .

[0054] The power generation device 50 includes one or more of a photovoltaic power generation device, a thermal power generation device, and a vibration power generation device. The specific type of the power generation device 50 can be set according to actual needs, and the embodiment of the present application does not limit it. It is understandable that the power conversion device 40 can be adaptively adjusted according to the specific type of the power generation device 50, so as to perform corresponding voltage and power conversion according to the charging parameters based on the power provided by the power generation device 50.

[0055] The power generation device 50 can fully utilize the energy in the environment. For example, the heat, vibration, and sound generated by the car can be fully utilized to achieve energy-saving and environmental protection effects.

[0056] In one embodiment, the parking lot 20 further includes an energy storage device 60 , which is connected to the electric energy conversion device 40 , and is used to store the electric energy provided by the electric energy conversion device 40 , and to provide the electric energy conversion device 40 with electric energy for charging.

[0057] The energy storage device 60 may include one or more of an energy storage battery and a flywheel energy storage device. The energy storage device 60 may store the electric energy generated by the power generation device 50 when the power consumption is low, so as to supply power to the electric energy conversion device 40 when a large amount of power is needed.

[0058] In some embodiments, the power conversion device 40 may also be connected to an external power source 70 , which may be a power grid. By connecting to the power grid, the power conversion device 40 may directly obtain power from the power grid.
