[0020] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, this embodiment provides a wiper with integrated signal light function, which includes a body controller, a wiper, a vehicle wiper control system, a dual-core LED signal light module, an LED drive control module, a music rhythm control module and a wiper light control module, which can realize two completely different functions of wiper and light;

[0022] The vehicle wiper control system is electrically connected to the wiper and is used to control the wiper action;

[0023] The body controller, vehicle wiper control system and music rhythm control module are all connected to the wiper light control module, the wiper light control module is connected to the LED drive control module, the LED drive control module is connected to the dual-core LED signal light module, and the dual-core LED signal light module is set on the wiper.

[0024] like Figure 3 As shown, the dual-core LED signal light module of this embodiment includes an LED lamp and a corresponding capacitor, and has two functions: yellow light (D1A-D19A) and white light (D1B-D19B). Each color can achieve multiple brightness levels through duty cycle control. The dual-core LED signal light module is controlled by an LED drive control module and can receive commands from the wiper light control module to achieve different lighting effects.

[0025] like Figure 2 As shown, the wiper light control module of this embodiment includes an MCU module, a first CAN transceiver and a third CAN transceiver. The first CAN transceiver and the third CAN transceiver both perform UART communication with the MCU module.

[0026] The LED drive control module includes a second CAN transceiver and an LED drive module;

[0027] The input end of the LED driver module communicates with the first CAN transceiver via the second CAN transceiver;

[0028] The output end of the LED driver module is connected to the input end of the dual-core LED signal light module.

[0029] The music rhythm control module communicates with the MCU module via UART via the third CAN transceiver.

[0030] In this embodiment, the MCU module uses the S9KEAZ128AMLH, and the LED driver module uses the E522.48. When driving in inclement weather such as dense fog and poor visibility, the driver can use the vehicle body controller to control the MCU module to issue a specific signal, causing the integrated signal light in the wiper to act as a warning light. By flashing a bright yellow light at different frequencies, it alerts drivers ahead or oncoming in the lane, thereby improving driving safety.

[0031] During daily driving and when the wiper function is not working, the signal light integrated in the wiper can act as a position light. When the vehicle turns, the body controller sends a corresponding turn signal to the MCU module, and then the MCU module sends a lighting command to the LED driver module to control the dual-core LED signal light module to perform the turn signal function and light up the yellow light.

[0032] The vehicle's music rhythm control module receives audio signals from the body controller, analyzes them, and converts them into corresponding bus signals. This bus signal is then transmitted to the MCU module, which controls the LED driver module, activating the dual-core LED signal light module to illuminate in rhythmic patterns of different colors and brightnesses. This music rhythm function enhances driver-vehicle interaction while also providing a certain social function. The music rhythm function can only be activated when the vehicle is in P gear. The MCU module receives the gear position signal from the body controller. Only when it determines that the vehicle is in P gear can it receive instructions from the music rhythm module and control the LED driver module to activate the lighting rhythm function. The body controller can select different modes, and the music rhythm function is only activated when the vehicle is in Camping Mode or Entertainment Mode.

[0033] like Figure 2 As shown, the wiper with integrated signal light function in this embodiment further includes an optical rain sensor assembly, which is connected to the vehicle wiper control system.

[0034] The optical rain sensor component collects information about the external environment's rain conditions and converts all of this information into specific signals that are transmitted to the vehicle's wiper control system. This controls the wipers to operate at a certain frequency, reducing the amount of rain on the vehicle's front and rear windshields, minimizing the impact of rain on the driver's driving, and improving driving safety.

[0035] like Figure 2 As shown, the wiper with integrated signal light function in this embodiment also includes an SBC module. The body controller communicates with the MCU module through the SBC module. The output end of the SBC module supplies power to the MCU module and the LDO module. The optical rain sensor component is powered by the SBC module after passing through the LDO module.

[0036] The working principle of this utility model is as follows:

[0037] The driver sends a signal to the wiper light control module through the vehicle body controller. Upon receiving the steering, warning, or music rhythm signals, the wiper light control module sends a lighting command to the LED driver control module, controlling the dual-core LED signal light module to perform the corresponding function and illuminate in different colors and effects. When implementing traditional wiper functions, the optical rain sensor component collects information about external rainfall and converts it into a specific signal, which is transmitted to the vehicle's wiper control system to control the wipers to operate at a certain frequency.

[0038] This new device integrates a dual-core LED signal light module into a traditional windshield wiper. Besides its normal function of clearing rain from the windows, it also utilizes the integrated signal light on its surface to create various lighting effects. It can function as a position light during normal driving and a turn signal when turning. In inclement weather such as heavy fog or rainstorms, where visibility is poor, the integrated signal light in the wiper can be used as a warning light to alert drivers ahead or oncoming traffic, thereby improving driving safety. When the vehicle is in camping mode, entertainment mode, or P gear, it can also activate a music rhythm function, enhancing driver-vehicle interaction while also achieving a certain level of social interaction.

[0039] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
