Car radio antenna structure

Abstract

This invention relates to a car radio antenna structure, comprising a base, a control unit, a servo unit, and a car active radio antenna. The base is assembled to a vehicle and has a movable part; the control unit is located within the base and is signal-connected to the car radio; the servo unit is located within the base and is signal-connected to the control unit; the car active radio antenna is located in the movable part, signal-connected to the control unit, and integrated with the servo unit. Thus, when not in use, the car active radio antenna can be horizontally retracted into the base. When the vehicle is started or the car radio is used after the vehicle is started, the control unit receives the control signal from the car radio and drives the servo unit, causing the servo unit to rotate the car active radio antenna within the movable part, raising the car active radio antenna from the base. The car active radio antenna can then be retracted or raised as needed, achieving better ease of use and reception.

Claims

1. A vehicle radio antenna structure, comprising: a body having at least one movable portion on its top, the body being assembled to a vehicle, wherein the body includes a housing and a bottom cover, the bottom cover being coupled to the bottom of the housing, the movable portion being disposed on the top of the housing, a control unit and a servo unit being disposed on the bottom cover, and the housing enclosing the control unit and the servo unit, the housing having a first limiting hole and a second limiting hole, the first limiting hole and the second limiting hole corresponding to each other and respectively located on both sides inside the movable portion, the vehicle active radio antenna having a shaft, one side of the shaft being coupled to the servo unit through the first limiting hole, and the other side of the shaft being movably disposed in the second limiting hole; a control unit disposed within the body and signal-connected to a vehicle radio of the vehicle; A servo unit is disposed within the housing and signal-connected to the control unit; and at least one vehicle active radio antenna is disposed within the movable part, and the vehicle active radio antenna is signal-connected to the control unit and is coupled to the servo unit. The control unit receives control signals from the vehicle radio and drives the servo unit, causing the servo unit to rotate the vehicle active radio antenna within the movable part.

2. The vehicle radio antenna structure as described in claim 1, wherein one end of the housing is provided with a stop portion, and one end of the movable portion is connected to the other end of the housing; or both ends of the movable portion are respectively connected to both ends of the housing.

3. The vehicle radio antenna structure as described in claim 1, wherein the housing is provided with a connecting hole that connects the bottom and both sides of the movable part, the vehicle active radio antenna is provided with a shaft, a spindle, a connector and a bolting part, the spindle is provided on one side of the shaft, the spindle is connected to the servo unit from one side of the connecting hole, the connector is provided on the bottom cover, the other side of the shaft is movably provided on the other side of the connecting hole, and the bolting part is connected to the other side of the shaft via the connector.

4. The vehicle radio antenna structure as described in claim 1, wherein a cable positioning part is provided at the bottom of the base, the cable positioning part is assembled to the vehicle, and the control unit is connected to the vehicle's vehicle radio via a wire through the cable positioning part.

5. The vehicle radio antenna structure as described in claim 1, wherein the control unit is connected to the vehicle radio via a wire, so that the control unit receives the signal from the vehicle radio via the wire, thereby driving the servo unit to rotate the vehicle active radio antenna in the movable part.

6. The vehicle radio antenna structure as described in claim 1, wherein the control unit further includes a preset angle control module and a stepless angle control module, the control unit receiving the signal of the vehicle radio via a wire, so that the control unit, in conjunction with the preset angle control module or the stepless angle control module, drives the servo unit, so that the servo unit drives the vehicle active radio antenna to rotate and move in the movable part to the desired angle.

7. The vehicle radio antenna structure as described in claim 1, wherein the servo unit includes at least one drive shaft, and one side of the vehicle active radio antenna is coupled to the drive shaft.

8. The vehicle radio antenna structure as described in claim 1, wherein the vehicle active radio antenna is columnar or sheet-shaped.
