Description

Technical Field

[0001] This utility model relates to the field of vehicle audio equipment technology, and in particular to a vehicle audio panel with ANCS push function. Background Technology

[0002] Car audio systems are multimedia playback systems installed in cars to provide audio-visual entertainment for passengers. They are also primarily car stereos for playback and navigation. Currently, the mainstream structure for car audio displays uses a TFT module + panel structure. The advantages of this solution are: a large display area and good picture quality.

[0003] A search revealed Chinese utility model patent CN222531817U, which discloses a car audio player system belonging to the field of in-vehicle audio player technology. The system includes a third-party player, a Bluetooth module, and a car navigation system. The third-party player connects to the car navigation system via the Bluetooth module, and the car navigation system connects to a microphone to receive audio data from the microphone. This system perfectly solves the connection and control problem between the original car head unit and an external third-party high-definition player through Bluetooth, achieving bidirectional control and stable transmission of audio streaming signals. It maintains low power consumption and low cost while ensuring high-quality music transmission. The third-party player can achieve all the functions of steering wheel control without an external control panel or steering wheel controller, opening a new path for the connection and control of original car head units and external third-party players in the car audio modification industry, achieving a perfect integration of the original car head unit and the player.

[0004] While the existing car audio players can meet basic usage needs, they can only play music and make hands-free calls via Bluetooth, but cannot receive mobile phone message notifications or display mobile phone notifications on the car audio system. Only high-priced car devices that integrate Wi-Fi and Bluetooth and support mobile phone interconnection such as CarPlay, HiCar, or Android Auto can achieve this function. These devices have high production costs and are not aesthetically pleasing. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] like Figure 1-3 As shown, the car audio panel with ANCS push function includes a plastic panel body 1. The plastic panel body 1 has a watch-shaped front cover 2 and several control buttons 3. A touch screen display 4 is located at the center of the watch-shaped front cover 2. A PCB circuit board is installed inside the plastic panel body 1. The PCB circuit board includes a Bluetooth main control circuit, a Bluetooth antenna, a main control power circuit, a button touch circuit, a touch screen driver circuit, and a touch indicator light circuit. The Bluetooth antenna, main control power circuit, button touch circuit, touch screen driver circuit, and touch indicator light circuit are all electrically connected to the Bluetooth main control circuit. It can be understood that the watch-shaped front cover 2 is designed in the shape of a watch and is embedded in the front end of the plastic panel body 1. The touch screen display 4 is also embedded in the front end of the watch-shaped front cover 2. The plastic panel body 1 is made of hard plastic.

[0022] Specifically, the Bluetooth main control circuit includes a BLE Bluetooth chip U2, a crystal oscillator Y1, capacitors C14 and C15. The Bluetooth antenna, crystal oscillator Y1, capacitors C14 and C15 are all connected to the BLE Bluetooth chip U2. Understandably, the BLE Bluetooth chip U2 uses a 6603 Bluetooth chip, which establishes a communication connection with the mobile phone via the BLE protocol and ANCS function, thereby obtaining system and app notifications from the phone. This eliminates the need for expensive in-vehicle devices that integrate Wi-Fi and Bluetooth and support CarPlay, HiCar, or Android Auto. Through wireless Bluetooth connection, audio content from the phone and other devices is transmitted to the car audio system for playback. Simultaneously, the BLE ANCS function displays notifications from the phone on the car audio system, significantly reducing costs.

[0023] Specifically, the main control power supply circuit includes a power management chip U3, resistors R1 and R43, capacitors C24 and C31. Resistors R1, R43, C24, and C31 are all connected to the power management chip U3, and resistors R43 and R1 are both connected to the BLE Bluetooth chip U2. It is understood that the power management chip U3 uses a 7805 chip, which is used to connect to an external power supply and convert it into a suitable voltage to power the aforementioned circuit.

[0024] Specifically, the button touch circuit includes a button touch chip U7, resistors R5 and R103, and the BLE Bluetooth chip U2, resistors R5 and R103 are all connected to the button touch chip U7. The touch screen driver circuit includes a touch screen driver chip U5, a crystal oscillator Y2, a capacitive touch chip U6, and a touch screen interface CN1. The capacitive touch chip U6 is connected to both the touch screen interface CN1 and the touch screen driver chip U5. The touch screen interface CN1 is connected to the touch screen display. The BLE Bluetooth chip U2 and the crystal oscillator Y2 are both connected to the capacitive touch chip U6. It is understood that the button touch chip U7 can be a general-purpose touch IC chip, etc. The touch screen driver chip U5 uses the AB5682A_B chip to drive and control the display content of the touch screen display 4, and the capacitive touch chip U6 uses the CST816D chip to sense touch signals on the touch screen display 4.

[0025] Specifically, the touch indicator circuit includes indicator LEDs 23, 25, 26, 27, 28, and 29, all of which are connected to the button touch chip U7. It is understood that these indicator lights can be general-purpose light-emitting diodes (LEDs) used to emit corresponding lights.

[0026] Understandably, this utility model has a reasonable design and unique structure. By setting a touch screen 4 in the center of the watch-shaped front cover 2 on the plastic panel body 1, its appearance is more unique and beautiful. By setting a Bluetooth main control chip and Bluetooth main control circuit to connect to the mobile phone, it can obtain the mobile phone's notification messages and display them through the touch screen 4. The mobile phone message display is achieved by using only Bluetooth connection. In addition, the design of the plastic panel greatly reduces the cost from the design point of view, and the manufacturing cost is also low.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
