Vehicle-mounted apparatus with functions of positioning, tracking and collision warning

Abstract

The invention relates to a vehicle-mounted apparatus with functions of positioning, tracking and collision warning, and belongs to the electronic technical field of automobiles. Ear plates are arranged on the left and right side walls of upper and lower shells; limiting surfaces are arranged on the end parts of the front and back side walls; an acceleration sensor is arranged on the left side wall or the right side wall of the upper shell; a circuit board with an emission unit is arranged on the bottom wall of the lower shell; the upper and lower ear plates are connected through screws, and a cantilever beam type metal substrate is crimped between the upper and lower ear plates; the metal substrate, and piezoelectric wafers which are pasted on the upper and lower sides of the metal substrate form a piezoelectric vibrator; a moving magnet I and a mass block are arranged on the upper and lower sides at the free end of the metal substrate respectively; a moving magnet II is mounted at the lower end of the mass block; the moving magnet I, the mass block and the moving magnet II form an excitation arm; the width of the inner cavities of the upper and lower shells is less than that of the metal substrate, and greater than that of the piezoelectric wafers; and a fixed magnet I is mounted on the top wall of the upper shell while a fixed magnet II is mounted on the bottom wall of the lower shell. The vehicle-mounted apparatus with the functions of positioning, tracking and collision warning has the advantages and characteristics of high environmental adaptability, wide effective frequency band, high power generation capacity, and high reliability; and meanwhile, the vehicle-mounted apparatus can be used as an independent part to be embedded in a hidden place of the vehicle body, so that the vehicle-mounted apparatus is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a vehicle positioning tracking and collision alarm device. Background technique [0002] Vehicle positioning and navigation systems have been widely used in real life. However, the existing positioning device has a single function, and mainly aims at guiding the driver to the destination. From a practical point of view, the vehicle positioning and tracking system can also realize functions such as real-time monitoring and reporting of vehicle speed, automatic alarm of major traffic accidents, or tracking of vehicle theft. The positioning system will not continue to work; in addition, the existing positioning systems are all external, can be closed or destroyed artificially, and cannot be used for speed monitoring and theft tracking. Therefore, in order to expand the functions and practicability of the positioning system, it is first necessary to solve...

However, the existing positioning device has a single function, and is mainly aimed at guiding the driver to the destination.

From a practical point of view, the vehicle positioning and tracking system can also realize functions such as real-time monitoring and reporting of vehicle speed, automatic alarm of major traffic accidents, or tracking of vehicle theft. The positioning system will no longer work; in addition, the existing positioning systems are external, can be artificially turned off or destroyed, and cannot be used for speed monitoring and theft tracking, etc.
