Problems solved by technology

[0004] Generally, the longer the antenna extends into the air, the better the signal. When the car is driving on different roads, the signal strength is different. When the signal is weak, it is difficult for the antenna to receive the signal. Most of the existing car antennas cannot adapt to different signal status

Abstract

The invention provides a car antenna, belongs to the field of vehicle antennas, and solves the problems that the existing car antenna cannot adapt to different signals and the like. A car antenna comprises a casing and an antenna disposed inside the casing, wherein the casing is further provided with a telescopic antenna and a driving device for driving the telescopic antenna to expand and contract, the casing is provided with a base, the base is fixedly mounted with a main board, one end of the telescopic antenna is connected to the main board, the other end of the telescopic antenna is fixedly connected with a sealing plug, the top of the casing is provided with an opening, and the sealing plug is used for sealing the opening; when extending, the sealing plug extends upwardly with the telescopic antenna; when contracting, the telescopic antenna contracts into the casing and curls into a spiral shape, a connection jack communicated with the main board is further disposed under the base, and the connection jack is connected to the receiving device inside the car and transmits signals. The car antenna is capable of adapting to the condition of different signals.

Description

technical field [0001] The invention belongs to the field of vehicle antennas, in particular to a vehicle antenna. Background technique [0002] A variety of different types of antennas are used in the automotive industry, including AM / FM radio antennas, Satellite Digital Audio Broadcasting Service (SDARS) antennas, Global Navigation Satellite System (GNSS) antennas, cellular antennas, and the like. Multi-band antenna assemblies are also commonly used in the automotive industry. Multi-band antenna assemblies typically include multiple antennas that cover and operate at multiple frequency ranges. [0003] Automotive antennas may be mounted or mounted on a vehicle surface, such as the vehicle's roof, trunk, or hood, to help ensure that the antenna has an unobstructed view upward or toward the sky. [0004] Generally, the longer the antenna extends into the air, the better the signal. When the car is driving on different roads, the signal strength is different. When the signa...
