[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present application belong to the scope of protection of the present application.

[0028] It should be noted that in the description of the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0029] In order to facilitate a clearer understanding of the embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0030] With the rapid development of science and technology, people's living standards and quality continue to improve. Cars have changed from a simple means of transportation to an indispensable "third space" in people's daily lives. This change has made smart cockpits an important consideration for future consumers when buying cars. At the same time, the popularity of consumer electronics products and the shift in scenarios have made consumers more and more accustomed to using various electronic products, indicating that consumers' preferences for in-vehicle entertainment information systems in the future may be similar to those for mobile phone applications.

[0031] Window glass, as an important part of the car, is the interface between the interior of the car and the outside world. Traditionally, window glass mainly performs basic functions such as sound insulation and light transmission. However, under the trend of intelligence, window glass is expected to become a new carrier for information display. But to realize this vision, the power supply of window glass has become a technical problem that needs to be solved urgently.

[0032] At present, there is no mature window glass power supply solution on the market. The existing window glass lifter mechanical structure does not support the layout of power cables. If the power cable is directly installed to supply power, the window glass needs to be raised and lowered frequently, and the required power cable is long, which not only increases the cost, but also may cause the power cable to be rolled into the window lifter guide rail during the lifting process and damaged, thus affecting the normal use of the window and driving safety.

[0033] In order to overcome at least some of the above-mentioned defects of the related art, the embodiments of the present application provide a power supply system and a vehicle for a vehicle window glass, which can realize wireless transmission of electric energy through the electromagnetic induction principle between a wireless charging transmitting coil installed on the vehicle to which the vehicle window glass belongs and a wireless charging receiving coil embedded in the vehicle window glass, so that the vehicle window glass can receive electric energy without the need for a physical connection based on a power cord, effectively realizing wireless power supply of the vehicle window glass, thereby helping to ensure the normal operation of various intelligent functions on the vehicle window glass, and the power supply system has a simple structure and is easy to maintain.

[0034] The following will provide an exemplary introduction to the power supply system for a vehicle window glass and the vehicle according to the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application.

[0035] Figure 1 It is a schematic structural diagram of a power supply system for a vehicle window glass provided by an embodiment of the present application. As Figure 1 shown, the power supply system includes: a wireless charging receiving coil 102 embedded in the vehicle window glass 101, a wireless charging transmitting coil 104 installed on the vehicle 103 to which the vehicle window glass 101 belongs, and an integrated circuit board 105 installed in the vehicle window glass 101 and connected to the wireless charging receiving coil 102;

[0036] The wireless charging transmitting coil 104 is connected to a low-voltage power supply circuit 106 in the vehicle 103; the low-voltage power supply circuit 106 is used to supply electrical energy to the wireless charging transmitting coil 104, so that the wireless charging transmitting coil 104 generates a changing magnetic field and transmits it to the wireless charging receiving coil 102; after the wireless charging receiving coil 102 senses the changing magnetic field through the principle of electromagnetic induction, an induced current is generated to charge the battery in the integrated circuit board 105.

[0037] It should be noted that the shapes, sizes, and specific layout positions of the wireless charging receiving coil 102 and the wireless charging transmitting coil 104 can be designed according to actual needs, and the embodiments of the present application do not make specific limitations on this.

[0038] For example, the wireless charging receiving coil 102 can be in a ring shape or a rectangular shape, etc., and be embedded at the edge or the center position of the vehicle window glass 101. The wireless charging transmitting coil 104 can be correspondingly installed at a position on the vehicle opposite to the vehicle window glass 101 to ensure the magnetic field transmission efficiency between the wireless charging receiving coil 102 and the wireless charging transmitting coil 104.

[0039] It should be noted that the low-voltage power supply circuit 106 refers to a circuit that supplies electrical energy to various electronic devices on the vehicle. These electronic devices include, but are not limited to, lighting systems, audio systems, and navigation systems, etc. The low-voltage power supply circuit 106 aims to ensure that these electronic devices can obtain stable and reliable electrical energy supply when the vehicle is running or parked. In the embodiments of the present application, connecting the wireless charging transmitting coil 104 to the low-voltage power supply circuit 106 in the vehicle can enable the low-voltage power supply circuit 106 to supply stable and reliable electrical energy to the wireless charging transmitting coil 104.

[0040] It can be understood that in the embodiments of the present application, the low-voltage power supply circuit 106 provides electrical energy for the wireless charging transmitting coil 104. When the electrical energy passes through the wireless charging transmitting coil 104, the wireless charging transmitting coil 104 generates a changing magnetic field. This magnetic field is then transmitted through the air to the wireless charging receiving coil 102, and the wireless charging receiving coil 102 senses this magnetic field through the principle of electromagnetic induction and generates an induced current. This induced current is then used to charge the battery on the integrated circuit board 105.

[0041] In some embodiments, some intelligent modules can be integrated on the integrated circuit board 105, such as environmental perception sensors, intelligent temperature control modules, and intelligent sunshade modules, etc. These modules can be powered by the battery on the integrated circuit board 105 to realize the intelligent functions of the window glass.

[0042] In some embodiments, a power conversion module can be added between the wireless charging receiving coil 102 and the integrated circuit board 105. This power conversion module can be used to convert the induced current generated by the wireless charging receiving coil 102 into a voltage and current suitable for charging the battery in the integrated circuit board 105. This can improve the charging efficiency, reduce energy loss, and protect the battery from the impact of excessive current or voltage.

[0043] In some embodiments, the power conversion module can be designed by combining circuit elements such as DC-DC converters, rectifiers, and filters. These circuit elements can be selected and configured according to actual needs to achieve efficient conversion and stable transmission of electrical energy.

[0044] In some embodiments, the power conversion module can be integrated on the integrated circuit board 105 to reduce the complexity and occupied space of the power supply system. At the same time, the power conversion module can also cooperate with other intelligent modules on the integrated circuit board 105 to achieve more intelligent power management.

[0045] It can be understood that the power supply system of the window glass provided by the embodiments of the present application realizes wireless transmission of electrical energy through the principle of electromagnetic induction between the wireless charging transmitting coil installed on the vehicle to which the window glass belongs and the wireless charging receiving coil embedded in the window glass, enabling the window glass to receive electrical energy without the need for a physical connection based on a power cord to charge the battery in the integrated circuit board, effectively realizing wireless power supply for the window glass, thereby helping to ensure the normal operation of various intelligent functions on the window glass, and the power supply system has a simple structure and is easy to maintain.

[0046] In some embodiments, the wireless charging receiving coil 102 is embedded at a first position at the bottom of the window glass 101, and the wireless charging transmitting coil 104 is installed at a second position on the inner door panel corresponding to the window glass 101. When the window glass 101 is raised and in a fully closed state, the first position and the second position can be aligned.

[0047] It should be noted that in the embodiments of the present application, the wireless charging receiving coil 102 is embedded at a first position at the bottom of the window glass 101; the wireless charging transmitting coil 104 is installed at a second position on the inner door panel corresponding to the window glass 101; the second position corresponds exactly to the first position when the window glass 101 is fully closed. The first position and the second position are designed to ensure that when the window glass 101 is raised and fully closed, the wireless charging receiving coil 102 can achieve the best alignment with the wireless charging transmitting coil 104 on the inner door panel. In this way, when the window glass 101 is raised and fully closed, a tight and stable magnetic field coupling can be formed between the wireless charging receiving coil 102 and the wireless charging transmitting coil 104, thereby achieving efficient wireless charging.

[0048] In some embodiments, the first position can be at the center of the bottom of the window glass 101 or at a position slightly offset to one side, which can maximize the coupling efficiency between the wireless charging receiving coil 102 and the wireless charging transmitting coil 104, while avoiding adverse effects on the structural strength and visual effect of the window glass 101.

[0049] Exemplarily, Figure 2 The figure is a schematic diagram of the arrangement position of a wireless charging receiving coil provided by an embodiment of the present application. As Figure 2 shown, the wireless charging receiving coil is embedded in the bottom area of the window glass.

[0050] Exemplarily, Figure 3 The figure is a schematic diagram of the arrangement position of a wireless charging transmitting coil provided by an embodiment of the present application. As Figure 3 shown, the wireless charging transmitting coil is installed on the inner door panel, and its installation position on the inner door panel corresponds to or aligns with the embedded position of the wireless charging receiving coil when the window glass is fully raised.

[0051] It can be understood that based on the power supply system of the window glass provided by the embodiments of the present application, once the window glass is completely closed and the wireless charging receiving coil is aligned with the wireless charging transmitting coil, the wireless charging process can start. At this time, the low-voltage power supply circuit provides stable electrical energy for the wireless charging transmitting coil, causing it to generate a changing magnetic field; the wireless charging receiving coil senses this changing magnetic field through the principle of electromagnetic induction and generates an induced current; this induced current is then used to charge the battery in the integrated circuit board, thereby providing a continuous power supply for various electronic devices on the window glass.

[0052] In some embodiments, the integrated circuit board 105 is installed at the third position at the bottom of the window glass 101, and when the window glass 101 is raised and in a fully closed state, the integrated circuit board 105 is still located below the inner and outer window sashes corresponding to the window glass 101.

[0053] It should be noted that the inner and outer window sashes are an important part of the automotive window system, which play a role in fixing, sealing, and protecting the window glass. The inner and outer window sashes are a sash structure composed of an inner part and an outer part. They are respectively located at the inner and outer edges of the window glass and are tightly connected to the door frame or window frame through a specific installation method. The inner and outer window sashes firmly fix the window glass to the door frame or window frame through their strong clamping force. This fixing function not only ensures the stability of the window glass during the opening and closing process but also prevents noise and safety hazards caused by the shaking of the window glass.

[0054] In the embodiments of the present application, the integrated circuit board 105 is installed at the third position at the bottom of the window glass 101 (which can be understood as a set area near the lower edge of the window glass 101), and the selection of this third position ensures that when the window glass 101 is raised and in a fully closed state, the integrated circuit board 105 is still located below the inner and outer window sashes corresponding to the window glass 101. In this way, such a design can not only avoid the integrated circuit board 105 from being squeezed or damaged by the window sashes but also ensure the stability and safety of the wireless charging process.

[0055] Exemplarily, Figure 4 FIG. is a schematic diagram of the layout position of an integrated circuit board provided by the embodiments of the present application. As Figure 4 shown, the integrated circuit board is installed in an area near the lower edge of the window glass.

[0056] It can be understood that the power supply system of the window glass provided by the embodiments of the present application, by installing the integrated circuit board at a specific position at the bottom of the window glass, effectively avoids the integrated circuit board from being squeezed or damaged by the window sashes and ensures the stability and safety of the wireless charging process.

[0057] In some embodiments, the power supply system further includes: an antenna embedded in the window glass 101; the antenna is connected to the integrated circuit board 105, and a wireless communication module is integrated on the integrated circuit board 105;

[0058] The antenna is used for signal transmission for wireless communication between the wireless communication module and a target device.

[0059] It should be noted that an antenna is a device capable of radiating and receiving electromagnetic waves, and it can convert guided waves and free space waves into each other. The antenna in the embodiments of the present application may be a microstrip antenna or a helical antenna, and these two antennas have the advantages of small volume, light weight, and easy integration.

[0060] It should be noted that the target device in the embodiments of the present application may be any electronic device capable of wireless communication inside or outside the vehicle. These devices can communicate with the antenna in the window glass through the wireless communication module to achieve data transmission and control instruction sending. Among them, in-vehicle devices are usually related to functions such as vehicle driving, entertainment, and navigation. For example, the entertainment system of the vehicle (such as an in-vehicle audio), the navigation system (such as GPS), the in-vehicle phone, the vehicle control module (such as the engine control unit, the body control module), etc. These devices can communicate with the antenna in the window glass through the wireless communication module to achieve data transmission and control instruction sending. Out-of-vehicle devices are usually located outside the vehicle but can communicate with the wireless communication module inside the vehicle. For example, personal electronic devices such as smartphones, tablets, and smartwatches; vehicle safety-related devices such as smart keys and vehicle trackers; and devices related to vehicle charging and home interconnection such as charging piles and smart home devices. These devices can also communicate with the antenna in the window glass through wireless communication to achieve functions such as remote control and data transmission.

[0061] In the embodiments of the present application, the power supply system further includes an antenna embedded in the window glass 101, and the antenna is connected to the integrated circuit board 105. Through the transmitting and receiving functions of the antenna, the wireless communication module integrated on the integrated circuit board 105 can perform data exchange with the target device to achieve the wireless communication function.

[0062] In some embodiments, the wireless communication module may include, but is not limited to, a Bluetooth module and a Wi-Fi module, etc. Bluetooth is a widely used short-range wireless communication technology suitable for communication between in-vehicle devices. It has a high data transmission rate and low power consumption, and supports connection between multiple devices. Wi-Fi is a wireless local area network technology based on the IEEE802.11 standard, suitable for communication between in-vehicle devices and out-of-vehicle devices. It has a high data transmission rate and a long communication distance, but relatively high power consumption.

[0063] It should be noted that the wireless communication module (such as the Bluetooth module and the Wi-Fi module) requires continuous power supply to maintain its normal operation. The wireless communication module needs to consume a certain amount of electrical energy to support its communication functions during operation, including signal transmission, reception and processing. Therefore, the wireless communication module usually needs to obtain a continuous power supply through a wired connection or a built-in battery. The embodiment of the present application charges the battery in the integrated circuit board 105 by using wireless charging to ensure that the battery is continuously charged, thereby continuously providing power to the wireless communication module.

[0064] It is understandable that the embodiment of the present application provides a highly integrated, intelligent and safe vehicle window glass power supply system. The system not only realizes the wireless charging function of the vehicle window glass, but also integrates wireless communication capabilities, providing users with a more convenient and intelligent vehicle experience.

[0065] In some embodiments, the target device is any vehicle-mounted device in the vehicle 103 that is capable of wireless communication.

[0066] In the embodiment of the present application, the antenna embedded in the vehicle window glass is used for signal transmission for wireless communication between the wireless communication module integrated on the integrated circuit board 105 and the vehicle-mounted device capable of wireless communication in the vehicle 103. Among them, any vehicle-mounted device capable of wireless communication in the vehicle 103 is an in-vehicle device, such as a vehicle-mounted audio system, a vehicle-mounted telephone, and a vehicle-mounted navigation system.

[0067] It can be understood that the embodiment of the present application embeds an antenna in the vehicle window glass and integrates a wireless communication module on the integrated circuit board in the vehicle window glass. The antenna can transmit signals for wireless communication between the wireless communication module integrated on the integrated circuit board and the on-board device in the vehicle that can perform wireless communication, thereby effectively realizing the interconnection between the wireless communication module and the on-board device.

[0068] In some embodiments, a charging management unit is integrated on the integrated circuit board 105;

[0069] The charging management unit is used to send a first request message to the in-vehicle infotainment system of the vehicle 103 when it is determined that the power of the battery in the integrated circuit board 105 is less than a first power threshold and the window glass 101 is not fully raised. The first request message is used to instruct the in-vehicle infotainment system to output a prompt message to raise the window glass 101 to charge the battery in the integrated circuit board 105.

[0070] In the embodiments of the present application, a charging management unit is integrated on the integrated circuit board 105. The charging management unit has the function of intelligently monitoring and managing the battery power, and can make corresponding decisions according to the current battery power and the state of the window glass, and send a request message to the vehicle's on-board infotainment system. Specifically, the charging management unit monitors the power of the battery in the integrated circuit board 105 in real time or periodically. When the power of the battery is lower than a preset first power threshold, the charging management unit starts further judgment logic. At this time, the charging management unit also detects the state of the window glass, that is, determines whether the window glass is in the fully raised state. If the window glass is not fully raised, the charging management unit sends a first request message to the on-board infotainment system of the vehicle 103. The first request message contains specific indication information for informing the on-board infotainment system that a prompt message needs to be output currently to remind the driver or passenger to raise the window glass. This prompt message can be presented through the display screen, speaker or other appropriate output devices of the on-board infotainment system. For example, the text information "Please raise the window for wireless charging" is displayed, or the corresponding voice prompt is played. After receiving this prompt message, the driver or passenger can choose whether to raise the window glass according to the actual situation. If the window glass is raised, the coupling effect between the wireless charging transmitting coil 104 and the wireless charging receiving coil 102 will be better, so that the battery in the integrated circuit board 105 can be charged more effectively.

[0071] It should be noted that the specific value of the first power threshold can be adaptively set based on actual applications, and the embodiments of the present application do not make specific limitations in this regard. For example, the first power threshold is 30%, 25% or 20%, etc.

[0072] It can be understood that by integrating the charging management unit in the power supply system of the window glass and setting the corresponding logic judgment and prompt mechanism in the embodiments of the present application, intelligent management of the battery power can be achieved.

[0073] In some embodiments, the charging management unit is further configured to:

[0074] When it is determined that the power of the battery in the integrated circuit board 105 reaches a second power threshold, a second request message is sent to the wireless charging transmitting coil 104, and the second request message is used to instruct the wireless charging transmitting coil 104 to stop generating the changing magnetic field for transmission to the wireless charging receiving coil 102.

[0075] In the embodiment of the present application, the charging management unit not only has the function of sending a first request message to the in-vehicle infotainment system when the battery power is lower than the first power threshold and the window glass 101 is not fully raised as described in the above embodiment, but also has the function of sending a second request message to the wireless charging transmitting coil 104 when the battery power reaches the second power threshold. Specifically, when the battery power in the integrated circuit board 105 is charged by the electric energy received by the wireless charging receiving coil 102 from the wireless charging transmitting coil 104 and gradually increases to the preset second power threshold, the charging management unit detects this change and generates a second request message. The second request message is a clear instruction for instructing the wireless charging transmitting coil 104 to stop generating a changing magnetic field. Because the basic principle of wireless charging is to obtain an induced current by inducing the changing magnetic field generated by the wireless charging transmitting coil 104 through the wireless charging receiving coil 102, thereby charging the battery. Therefore, when the battery is already full or nearly full, it will no longer make sense to continue to generate a changing magnetic field, but may waste energy or generate unnecessary electromagnetic interference. The charging management unit sends the second request message to the wireless charging transmitting coil 104 through a certain communication interface to instruct the wireless charging transmitting coil 104 to stop generating the changing magnetic field.

[0076] In some embodiments, when the charging management unit determines that the power level of the battery in the integrated circuit board 105 reaches the second power threshold, it can send a second request message to the control unit of the wireless charging transmitting coil 104. After receiving the second request message, the control unit will immediately stop supplying power to the wireless charging transmitting coil 104 or adjust its working state to stop generating a changing magnetic field.

[0077] It should be noted that the second power threshold can be set to a safety threshold when the battery is fully charged or nearly fully charged to ensure that the battery will not be damaged or its service life will be shortened due to overcharging. The specific value of the second power threshold can be adaptively set based on actual applications, and the embodiments of the present application do not specifically limit this. For example, the second power threshold is 80%, 90% or 95%, etc.

[0078] For example, Figure 5 A schematic diagram of a process of charging a vehicle window glass provided in an embodiment of the present application is shown in FIG. Figure 5As shown, when the power of the window glass is less than the first power threshold, it is determined whether the window glass is fully raised; if the window glass is fully raised, charging for the window glass starts, and then charging ends when the power of the window glass reaches the second power threshold; if the window glass is not fully raised, the vehicle head unit (i.e., the in-vehicle infotainment system) prompts to raise the window glass for charging; and then it is determined again whether the window glass is fully raised; if the window glass is fully raised at this time, charging for the window glass starts, and then charging ends when the power of the window glass reaches the second power threshold; if the window glass is still not fully raised, after waiting for 10 minutes (this waiting time can be customized), the vehicle head unit prompts to raise the window glass for charging again.

[0079] It should be noted that the power of the window glass in the embodiments of this application is the power of the battery in the integrated circuit board installed in the window glass.

[0080] It can be understood that in the embodiments of this application, by integrating a charging management unit with intelligent power management and charging control functions in the window glass power supply system and setting corresponding logic judgment and request message mechanisms, precise control and optimization of the battery charging process can be achieved. This not only improves the reliability and safety of the power supply system, but also helps to extend the service life of the battery and reduce maintenance costs.

[0081] In some embodiments, the charging management unit is further configured to:

[0082] When it is determined that the window glass 101 is in a fully raised state, control the power of the battery in the integrated circuit board 105 to be maintained within a target power range.

[0083] In the embodiments of this application, the charging management unit not only has the function of monitoring the battery power, but also has the ability to precisely control the battery power when the window glass is in a fully raised state.

[0084] In some embodiments, a target power range can be preset according to the characteristics of the battery in the integrated circuit board 105 (such as capacity, charge and discharge efficiency, etc.) and the vehicle usage requirements. This target power range can be set to an interval that neither brings safety hazards due to excessive power nor affects the normal operation of the integrated circuit board 105 due to too low power. For example, the target power range is 60%-80%.

[0085] In some embodiments, the charging management unit can monitor the status of the window glass in real time through the in-vehicle communication bus (such as the CAN bus) or other sensors. When it is detected that the window glass is fully raised, the charging management unit will activate the power retention mode. In this power retention mode, if the power of the battery in the integrated circuit board 105 is lower than the lower limit of the target power range, the charging management unit will instruct the wireless charging receiving coil 102 to continue receiving electrical energy from the wireless charging transmitting coil 104 to charge the battery until the battery power reaches or approaches the median of the target power range.

[0086] It can be understood that in this embodiment, by expanding the functions of the charging management unit, when the window glass is fully raised, the charging management unit automatically maintains the battery power within a safe and reasonable range. This not only improves the stability and reliability of the power supply system, but also extends the service life of the battery and reduces the vehicle maintenance cost. At the same time, the intelligent power management strategy also provides a more convenient and safe driving experience for the driver.
