Car radio antenna structure

Abstract

This invention relates to a car radio antenna structure, comprising a housing, a car active radio antenna, a drive mechanism, and a control unit. The housing is assembled into a vehicle; the car active radio antenna is retractable at one end of the housing; the drive mechanism is located within the housing and connected to the car active radio antenna; the control unit is signal-connected to the drive mechanism and the vehicle's car radio. Thus, when the vehicle is started or stopped, or when the car radio is turned on or off, the control unit receives relevant on / off control signals to activate the drive mechanism, causing the car active radio antenna to extend or retract within the housing. This allows the car active radio antenna to be extended or retracted according to usage requirements, achieving better ease of use and improved radio reception.

Claims

1. A vehicle radio antenna structure, comprising: a housing for assembly to a vehicle; a vehicle active radio antenna movably disposed at one end of the housing in a telescopic manner; a drive mechanism disposed within the housing and connected to the vehicle active radio antenna; and a control unit signal-connected to the vehicle active radio antenna, the drive mechanism, and a vehicle radio of the vehicle; wherein the drive mechanism includes an actuation unit, a transmission unit, a movable connector, a first switch, and a second switch; the actuation unit is disposed at the other end of the housing and signal-connected to the control unit; the transmission unit is connected to the actuation unit; the movable connector is movably disposed on the transmission unit and connected to the vehicle active radio antenna, thereby causing the vehicle active radio antenna and the transmission unit to be misaligned; the first switch is disposed at one end of the housing and signal-connected to the control unit; and the second switch is disposed at the other end of the housing and signal-connected to the control unit.
