Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a wireless power supply transmitting module, receiving module, wireless function module and system. Background Technology

[0002] The Around View Monitor (AVM) system uses four fisheye cameras installed on the front, rear, left, and right sides of a commercial vehicle to acquire 360° environmental information around the vehicle. The fisheye images from the four cameras are then transmitted to a controller, where they are processed and combined to create a panoramic image of the vehicle's surroundings, which is then fed back to the driver, thus eliminating blind spots. The AVM system is also known as a 360° panoramic surround view system because it can observe the situation around the vehicle in real time, providing great convenience for parking and entering and exiting narrow roads.

[0003] Existing panoramic parking systems are usually pre-installed on vehicles. When installing cameras and controllers, automakers need to consider additional space requirements during the design phase, which adds an extra step during subsequent vehicle assembly and is not conducive to improving production speed.

[0004] Furthermore, for vehicles that do not come with an AVM system, if an AVM system needs to be configured separately, i.e., when installing an AVM in the aftermarket, considering the power supply requirements and aesthetics of the various functional modules in the AVM system, such as camera components and video receiving components, it is inevitable to disassemble some in-vehicle components to find suitable installation locations for wiring. This may result in inconvenient installation and the possibility of damaging other components. Utility Model Content

BQ51025 establishes an I / O connection with ORX1210 through path 2-3. 2 The communication link is as follows: The ORX1210 PMIC provides power to the Sensor OX01G10, Microcontroller SNCC70, Wireless Communication Interface Chip RTC6763, and Wireless Communication Gain Chip RTC6681 via paths 2-4, 2-5, 2-6, 2-7, 2-8, and 2-9. The LENS acts as a lens, inputting the surrounding conditions of the car as light into the OX01G10. The OX01G10 converts the light into electrical signals and transmits them in a specific format to the MIPI interface of the Microcontroller SNCC70 via path 2-10. The SNCC70 processes and compresses the data before transmitting it via path 2-12 to the SPI interface of the Wireless Communication Interface Chip RTC6763 for further processing. The RFOUT pin of the RTC6763 transmits the data via path 2-11 to the Wireless Communication Gain Chip RTC6681 for amplification, and then via path 2-13 to the antenna interface BF2520 for data transmission via the antenna.

BQ51025 converts the induced AC voltage into a DC voltage, which is input to the voltage input terminal of the PMIC model ORX1210 through path 3-2. BQ51025 establishes an I / O connection with ORX1210 through path 3-3. 2 The ORX1210 provides power to the microcontroller SNCC71, the wireless communication interface chip RTC6763, and the wireless communication gain chip RTC6681 via paths 3-4, 3-5, 3-6, 3-7, and 3-8. The antenna receives signals and sends them into the circuit as electrical signals through the antenna interface BF2520. These signals are then transmitted to the switch via path 3-12 and then to the input pin of the wireless communication interface chip RTC6763 via path 3-11. The RTC6763 processes the received signals and transmits them to the SPI interface of the SNCC71 via path 3-8. The SNCC71 processes the received signals and transmits them to the vehicle's LCD screen (display device) via path 3-13 for function display. Simultaneously, the SNCC71 can send data sequentially via paths 3-8, 3-9, 3-10, and 3-12.
