Vehicle-mounted navigating instrument

Abstract

The invention provides a vehicle-mounted navigating instrument, including a navigating instrument body, a base, a left supporting frame and a right supporting frame. The left supporting frame and theright supporting frame are fixedly connected with dampers in the vertical directions, the upper ends of piston rods of the dampers are connected with the upper ends of the two sides of the navigatinginstrument body through rotary dampers, the left supporting frame and the right supporting frame are fixedly connected on the base correspondingly, kinetic energy given to the navigating instrument bychange of the vehicle speed and the kinetic energy given to the navigating instrument by a vehicle bump can be absorbed and converted to gravitational potential energy of the navigating instrument body and mechanical energy of the dampers in the vertical directions and the rotary dampers by the dampers in the vertical directions and the rotary dampers to ensure whole stability of the vehicle-mounted navigating instrument, the vehicle-mounted navigating instrument is not prone to being dumped, bouncedand moved, and a safety factor in the process of driving is improved.

Description

technical field [0001] The invention belongs to the technical field of navigators, in particular to a vehicle-mounted navigator. Background technique [0002] With the development of the economy, the popularization of cars and the construction of roads, more and more people choose to buy private cars as a means of transportation. Navigation is indispensable in the driving process. However, many cars are not equipped with navigators when they leave the factory. Generally choose to refit and add a navigator or use a peripheral navigator. Refitting will change the original circuit of the car, which has potential safety hazards. The peripheral navigator is usually placed on the car workbench. When the car starts, accelerates or brakes, the navigation The navigator may fall over, or when the car is driving on a road with bad road conditions, the navigator will bounce or move with the up and down bumps of the car, etc., there are potential safety hazards in the driving process, an...
