Lightning protecting and lightning arresting device integrated on vehicle-mounted antenna

Abstract

The invention discloses a lightning protection and lightning protection device integrated on a vehicle-mounted antenna, which is characterized in that it comprises a vehicle-mounted antenna and a lightning protection bracket, the lightning protection bracket is fixedly arranged on the vehicle-mounted antenna, and the lightning protection bracket is provided with There are lightning protection rod sets with symmetrical distribution. The present invention is applied in the technical field of lightning protection and lightning protection of vehicle-mounted antennas on automobiles. Lightning protection brackets and symmetrically distributed lightning protection rod sleeves are installed on the vehicle-mounted antennas of automobiles through hinged rods, and connected by setting the upper and lower ends of the vehicle-mounted antennas. The head and the lower connecting head are fixed on the top of the car, and then the left and right symmetrical and interconnected lightning protection caps and connecting bending rods are arranged on the lightning protection rod sleeve. By forming an evenly distributed induction charge layer around the lightning protection cap and connecting bending rods, By forming a relatively evenly distributed electric field environment in the induced charge layer and thunderclouds, the probability of lightning strikes is significantly reduced, and the lightning protection method that induces lightning to itself is fundamentally changed to achieve the beneficial effect of effective lightning protection for the car's on-board antenna.

Description

technical field [0001] The invention relates to a lightning protection and lightning protection device integrated on a vehicle-mounted antenna, which belongs to the technical field of the automobile industry. Background technique [0002] The traditional lightning rod is installed at the highest point of the lightning protection object. When lightning occurs, this highest point and the thundercloud form an extremely unevenly distributed electric field environment, which makes the air between the thundercloud and the lightning rod easy to be broken down, and the lightning current is extremely high. Easy to discharge lightning energy to the earth through the lightning rod. In fact, this lightning protection method that discharges lightning energy by guiding the lightning to itself is more likely to cause direct lightning strikes. The traditional lightning rod that guides the lightning to itself and discharges lightning energy to the ground cannot provide protection for cars, e...

In fact, this lightning protection method that discharges lightning energy by guiding the lightning to itself is more likely to cause direct lightning strikes. The traditional lightning rod that guides the lightning to itself and discharges lightning energy to the ground cannot provide protection for cars, especially vehicle-mounted antennas.
