Abstract

The invention relates to a pointing device of a pure mechanical structure, in particular to a vehicle pointing device based on a differential gear train. In order to provide the pointing device which is of a pure mechanical structure and high in reliability, the pointing device comprises a box body and a center shaft which stretches into the box body from the top end of the box body and is provided with a pointing mark, and a wheel A shaft and a wheel B shaft stretch into the box body from the left side and the right side of the box body respectively. A first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a fifth bevel gear, a sixth bevel gear and a planet gear are arranged in the box body; in the straight running process of the vehicle, the center shaft is stationary, and the pointing mark is stationary; when the vehicle turns, the planet wheel drives the center shaft to rotate in the opposite direction, the rotating angle is the same as the turning angle of the vehicle, the direction pointed by the mark is still unchanged, and finally the purpose of pointing in the given direction is achieved.

Description

technical field [0001] The invention relates to a pointing device with a purely mechanical structure, in particular to a vehicle pointing device based on a differential gear train. Background technique [0002] In today's life, pointing devices are closely related to daily life. The guide devices mainly used are compass and GPS positioning. Among them, the working principle of the guide device is mainly to use the geomagnetic field to complete the pointing of the north and south poles, but the guide device made by this principle has very poor stability. Because it depends too much on the earth's magnetic field, which is very unstable. Solar activity such as magnetic storms can disrupt the magnetic field and disable guidance equipment. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a vehicle pointing device based on a differential gear train. The device adopts a purely mechanical structure and has...
