Vehicle-mounted electromagnetic oscillation signal receiving device

Abstract

The invention discloses a vehicle-mounted electromagnetic oscillation signal receiving device. The device comprises magnetic rod core inductors and a substrate arranged at the bottom portion. The leftand right two ends of the substrate are signal output ports respectively. Frequency signals mainly received by the different magnetic rod core inductors in the device are different; and the receivedfrequency signals are input to vehicle-mounted communication and entertainment equipment from the signal output ports of the substrate through signal transmission lines. The device reduces use of antennas; and by designing reception of the different vehicle-mounted communication and entertainment equipment signals in one electromagnetic oscillation signal receiving device, and using the magnetic rod core inductors to receive the signals, the device is not only beautiful but also very practical.

Description

technical field [0001] The invention relates to the field of vehicle signal receiving, in particular to a vehicle electromagnetic oscillation signal receiving device. Background technique [0002] With the progress of society and the improvement of living standards, cars are becoming more and more popular, and there are more and more communication and entertainment devices (radio, telephone, Bluetooth, navigation, WIFI, TV, etc.) in the car. For equipment signal reception, most of the car roofs are equipped with one or more long pigtail antenna poles to receive the required signals, which not only affects the appearance, but also is extremely inconvenient to enter and exit the parking lot and garage. It's extremely cumbersome to screw it down and screw it back on. [0003] Later, some people used springs and iron rods to shrink or put a small piece of wire-wound PCB board into the fish-fin plastic shell to replace the long pigtail antenna rod, but this can only solve the pr...

Problems solved by technology

[0002] With the progress of society and the improvement of living standards, cars are becoming more and more popular, and there are more and more communication and entertainment devices (radio, telephone, Bluetooth, navigation, WIFI, TV, etc.) in the car. For equipment signal reception, most of the car roofs are equipped with one or more long pigtail antenna poles to receive the required signals, which not only affects the appearance, but also is extremely inconvenient to enter and exit the parking lot and garage. It's extremely cumbersome to screw it down and screw it on again.

[0003] Later, some people used springs and iron rods to shrink or put a small piece of wire-wound PCB board into the fish-fin plastic shell to replace the long pigtail antenna rod, but this can only solve the problem of entering and exiting the parking garage and car washing. , on the contrary, the signal reception effect of communication and entertainment equipment is extremely poor, which cannot meet the daily needs of car owners.
