Description

technical field [0001] The invention relates to the field of vehicle navigation, in particular to a GPS navigator for vehicles. Background technique [0002] Car navigator is a driving auxiliary device that can help users accurately locate the current location, calculate the itinerary according to the predetermined destination, and guide the user to the destination through map display and voice prompts. [0003] Car navigators generally include a chassis for accommodating internal circuit boards and a display panel assembly. The display panel assembly is installed at the upper opening of the chassis to block the upper opening of the chassis. The orthographic projection area of ​​the display panel is larger than that of the chassis. The upper opening of the upper part is installed near the operating console of the cab, the chassis is embedded in the operating console, and the display panel assembly is exposed on the outer surface of the operating console to facilitate users t...

AI Technical Summary

Problems solved by technology

Another example is that the chassis is integrally formed, and its various boards cannot be disassembled. As a result, the circuit board needs to be removed after the display panel assembly is removed for subsequent maintenance. The circuit board is taken out and then repaired. This method greatly wastes maintenance personnel's time. time

Another example is that when the navigator is installed on the car console, it is still fixed with simple bolts, the fixation is extremely unstable, and the fixation effect is poor, etc.
