Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted navigation, and particularly relates to a vehicle-mounted navigator adopting a snap-on connection. Background Art

[0002] Car Navigation is a driving assistance device designed specifically for vehicles. It can help drivers accurately locate their current location and calculate the best driving route based on the preset destination. This process mainly relies on the Global Positioning System (GPS) to obtain real-time location information. Car Navigation is usually equipped with a detailed electronic map, which provides direction guidance to the driver through screen display and voice prompts until the driver reaches the destination.

[0003] The screen and host of the existing car navigation system are generally connected by screws. The screw-fixed structure requires users to use tools to disassemble and assemble the equipment when they need to perform equipment maintenance, troubleshooting or system upgrades. This is not only cumbersome to operate, but may also cause trouble due to the loss of screws or difficulty in resetting, increasing maintenance costs and difficulty. Therefore, we hope to design a car navigation system with a new structure to solve this problem. Utility Model Content
