[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figures 1-5 As shown, a vehicle navigation device with voice recognition function includes a rear shell 1 and a mounting base 2. A front shell 3 is fixedly connected to the front end of the rear shell 1. A display screen 301 is provided on the inner side of the front shell 3. A support rod 4 is fixedly connected to the upper end of the mounting base 2. A spherical connector 5 is fixedly connected to the end of the support rod 4 away from the mounting base 2. A connecting seat 6 is fixedly connected to the rear end of the rear shell 1. The spherical connector 5 is rotatably connected to the inside of the connecting seat 6. An adjustment groove 7 is provided inside the connecting seat 6. An adjustment screw 8 is threadedly connected to the upper end of the connecting seat 6. A knob 9 is fixedly connected to one end of the adjustment screw 8. The end of the adjustment screw 8 away from the knob 9 extends through the upper end of the connecting seat 6 into the interior of the adjustment groove 7 and is rotatably connected to a push block 10. A rubber anti-slip block 11 is fixedly connected to the lower end of the push block 10. The end of the rubber anti-slip block 11 away from the push block 10 is arc-shaped and abuts against the outer surface of the spherical connector 5.

[0024] Furthermore, the display screen 301 is used to display various information from the in-vehicle navigation device, including maps, routes, and voice recognition feedback.

[0025] Furthermore, the spherical connector 5 allows the connector 6 to rotate. By rotating the connector 6, the display screen 301 can be adjusted in multiple directions to obtain the optimal viewing angle. The rubber anti-slip block 11 is used to fix the connector 6. By rotating the knob 9 to drive the adjusting screw 8 to rotate, the push block 10 can drive the rubber anti-slip block 11 to move closer to or away from the spherical connector 5. When the rubber anti-slip block 11 abuts against the outer surface of the spherical connector 5, the rotation of the connector 6 will be restricted due to the friction of the rubber anti-slip block 11, thus fixing the position of the connector 6 and ensuring that the display screen 301 will not move after the position is adjusted.

[0026] Furthermore, the rear shell 1 is internally equipped with a power module 12, a microprocessor 13, and a voice module 14. The microprocessor 13 is electrically connected to the power module 12, the display screen 301, and the voice module 14. The voice module 14 and the display screen 301 are both electrically connected to the power module 12.

[0027] Furthermore, the power module 12 provides power support for the vehicle navigation device, ensuring the normal operation of components such as the display screen 301, voice module 14, and microprocessor 13. The microprocessor 13 is the core control unit of the vehicle navigation device, responsible for processing input data and voice commands, and controlling the operation of components such as the display screen 301 and voice module 14. The voice module 14 is used to receive the user's voice commands and convert them into digital signals for processing by the microprocessor 13.

[0028] Furthermore, a sound insulation plate 22 is fixedly connected inside the rear shell 1. A through groove 15 is provided through the lower end of the rear shell 1 on the left side of the sound insulation plate 22. A microphone 16 is provided inside the through groove 15. The microphone 16 is electrically connected to the voice module 14. The microphone 16 is used to receive the voice commands of the car owner and transmit the sound signal to the voice module 14 for processing.

[0029] Furthermore, the lower end of the rear shell 1, located on the right side of the sound insulation plate 22, has several evenly distributed strip-shaped heat dissipation grooves 17. The lower end of the strip-shaped heat dissipation grooves 17 has a through-hole mounting groove 18, and the upper end of the rear shell 1 has a through-hole exhaust groove 19. The exhaust groove 19 is equipped with several evenly distributed cooling fans 20. The strip-shaped heat dissipation grooves 17 are used to introduce external air, and the cooling fans 20 are used to exhaust the hot air generated when the electronic components are working. The cooperation between the strip-shaped heat dissipation grooves 17 and the cooling fans 20 can accelerate airflow, promote the exhaust of hot air, improve heat dissipation efficiency, and prevent the device from overheating.

[0030] Furthermore, the sound insulation plate 22 has a pre-drilled wiring hole to provide a path for the connection between the microphone 16 and the voice module 14. The sound insulation plate 22 is used to separate the area where the microphone 16 is located from the area where the cooling fan 20 is located, thereby reducing the interference caused by the noise generated by the components inside the vehicle navigation device during operation on the microphone 16, which helps to improve the sound collection effect of the microphone 16 and thus improve the accuracy of voice recognition.

[0031] Furthermore, dustproof nets 21 are fixedly connected to the openings of the through slot 15, the strip heat dissipation slot 17, and the exhaust slot 19. The dustproof nets 21 are installed at the openings of the through slot 15, the strip heat dissipation slot 17, and the exhaust slot 19 to prevent dust from entering the interior of the device and protect the electronic components inside the device.

[0032] Working principle: When in use, the in-vehicle navigation device is connected to the vehicle's power supply. The power module 12 converts the vehicle's power supply into appropriate voltage and current to supply all components inside the device, including the display screen 301, voice module 14, and microprocessor 13. During navigation, the display screen 301 displays map and route information for the driver to view in real time. When the driver controls the device using voice, the microphone 16 converts the sound signal into an electrical signal and transmits it to the voice module 14. The voice module 14 converts the received audio signal into a digital signal and transmits it to the microprocessor 13. The microprocessor 13 processes the data based on the feedback voice commands, recognizes the driver's instructions, and controls the display screen accordingly. When the display screen 301 displays the corresponding feedback information and the angle of the display screen 301 needs to be adjusted, the car owner can rotate the knob 9 to make the adjusting screw 8 move the push block 10 and the rubber anti-slip block 11 away from the spherical connector 5. At this time, the connecting seat 6 can rotate, allowing the car owner to adjust the angle of the display screen 301 to obtain the best viewing position. After the display screen 301 is adjusted to a suitable angle, the knob 9 is rotated again to make the rubber anti-slip block 11 abut against the surface of the spherical connector 5. The friction of the rubber anti-slip block 11 will limit the movement of the connecting seat 6 and fix the position of the connecting seat 6, thereby fixing the position of the display screen 301 and ensuring that the display screen 301 will not move after the car owner adjusts the angle of the display screen 301.
