A vehicle operation positioning device

Abstract

The utility model discloses a vehicle operation positioning device belongs to vehicle operation management technical field, the device includes casing, apron and built -in PCB board, is equipped with positioning module and communication module on the PCB board. The innovative point lies at: casing and apron are made of engineering plastics, and its inner surface has deposited the metal conductive layer of constituting electromagnetic shield. The metal conductive layer is equipped with the hollow area of constituting antenna window in the area of directly facing antenna radiator, to solve the contradiction between full shielding and signal transmission. The metal conductive layer adopts the multilayer composite structure of nickel phosphorus alloy base layer, pure copper barrier layer and silver main body conductive layer, and combines the plasma pretreatment to plastic matrix, and the adhesion of metal layer and matrix is strengthened. The utility model has excellent electromagnetic shielding efficiency, stable wireless signal transmission capacity and excellent environmental tolerance and reliability, and is especially suitable for vehicle operation management.
