[0024] This utility model provides a vehicle-mounted terminal device based on UWB and BeiDou positioning, using a multi-mode fusion positioning system.

[0025] The processor in the control unit 4 processes and analyzes the positioning data collected by the UWB module 5 and the Beidou module 6 to obtain the vehicle's accurate location information. It can perform UWB positioning and Beidou positioning on the vehicle, thereby realizing multi-mode fusion positioning, which effectively improves positioning accuracy and stability. Furthermore, the lower box 1 and the upper box 2 can be quickly installed and fixed through the locking component.

[0026] As a preferred technical solution of this application, the control unit 4 also includes a 4G / 5G module, a Wi-Fi module and a Bluetooth module.

[0027] The inclusion of 4G / 5G, Wi-Fi, and Bluetooth modules enables the vehicle-mounted terminal to connect to the internet, allowing for real-time data transmission and remote monitoring.

[0028] As a preferred technical solution of this application, a hollow heat dissipation vent is provided on the upper right side of the upper box 2, and the heat dissipation vent on the upper right side of the upper box 2 is aligned with the control unit 4 inside the upper box 2.

[0029] The perforated heat dissipation vents allow the heat generated by the control unit 4 during operation to dissipate quickly, preventing damage due to overheating and improving its lifespan and stability.

[0030] As a preferred technical solution of this application, a protective cover 3 is fixedly installed on the front side of the upper box 2 by bolts, and the protective cover 3 is flush with the opening at the right end of the lower box 1.

[0031] By removing the protective cover 3 at the front end of the upper box 2, the control unit 4 can be inspected through the opening created by removing the protective cover 3 from the upper box 2 and the opening at the right end of the lower box 1, ensuring that all components can be seen and inspected in order to find and resolve any potential problems or malfunctions.

[0032] As a preferred technical solution of this application, the locking assembly includes an active rod 7, which is rotatably installed in the left end of the lower box 1. Double synchronous pulleys 8 are installed in the rear end of the active rod 7 and the right end of the lower box 1. A first synchronous belt 9 is sleeved on the two sets of double synchronous pulleys 8. A connecting rod 10 is rotatably installed in the left and right ends of the lower box 1. A single synchronous pulley 11 is fixedly installed on the two sets of connecting rods 10. Two sets of second synchronous belts 12 are sleeved on the two sets of single synchronous pulleys 11 and the two sets of double synchronous pulleys 8. A first bevel gear 13 is fixedly installed at the front and rear ends of the two sets of single synchronous pulleys 11. Two sets of second bevel gears 14 are rotatably installed at the left and right ends of the lower box 1. Insert rods 15 are threadedly inserted into the four sets of second bevel gears 14.

[0033] By rotating the drive rod 7, two sets of double synchronous pulleys 8, the first synchronous belt 9, two sets of connecting rods 10, two sets of single synchronous pulleys 11, two sets of second synchronous belts 12, four sets of first bevel gears 13 and four sets of second bevel gears 14 are driven to rotate, thereby causing four sets of insertion rods 15 to slide out. This allows the lower box 1 and the upper box 2 to be quickly locked during installation, making the installation and disassembly of the equipment more convenient and faster. It avoids the loosening or damage that may occur when using bolts for installation, and improves the stability and safety of the equipment.

[0034] As a preferred technical solution of this application, the cross-sections of the four sets of plug rods 15 at their left and right opposite ends are all square.

[0035] The square design makes the insertion rod 15 more stable when it slides out, and it is less likely to rotate or wobble, which further improves the installation stability and safety of the equipment.

[0036] Working principle: When installing the lower box 1 and the upper box 2, the active rod 7 is rotated. The rotation of the active rod 7 drives the two sets of double synchronous pulleys 8 and the first synchronous belt 9 to rotate. At the same time, the rotation of the two sets of double synchronous pulleys 8 drives the two sets of connecting rods 10, the two sets of single synchronous pulleys 11 and the two sets of second synchronous belts 12 to rotate. The rotation of the two sets of single synchronous pulleys 11 drives the four sets of first bevel gears 13 and the four sets of second bevel gears 14 to rotate. As the four sets of second bevel gears 14 rotate, the four sets of insertion rods 15 slide out from the lower box 1 and slide out from the left and right ends of the upper box 2, thereby locking the lower box 1 and the upper box 2 during installation. In use, the UWB module 5 and the Beidou module 6 on the control unit 4 receive signals to perform UWB positioning and Beidou positioning of the vehicle, thereby realizing multi-mode fusion positioning, which effectively improves positioning accuracy and stability. Furthermore, the setting of 4G / 5G module, Wi-Fi module and Bluetooth module enables the vehicle terminal device to connect to the Internet.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
