Description

Automobile antenna structure

Technical Field

The utility model relates to an auto-modification accessory, especially an automobile antenna structure.

Background

Digital Audio Broadcasting (DAB for short) is the third generation Broadcasting-Digital signal Broadcasting following the traditional AM and FM analog Broadcasting, which provides sound with quality close to CD, Broadcasting and business-machine unlimited additional data service, has the advantages of noise resistance, interference resistance, wave propagation fading resistance, suitability for high-speed mobile reception and the like, and ensures the quality of received signals during fixing, carrying and moving. However, FM broadcasts have been stopped in some countries and many cars are not equipped with DAB antennas. Therefore, there is a great demand for installing a DAB antenna in these automobiles, and when the owners of this part of automobiles need to listen to DAB broadcasting, the DAB antenna needs to be installed (of course, a DAB receiving module or a navigation host with DAB function needs to be installed). There are two main types of DAB antennas currently on the market, the first type is an antenna attached to the windshield of an automobile, but these antennas have the disadvantage of being mounted on the windshield of the automobile, which affects the appearance. More importantly, there are many german vehicles in which the windshield has a thermal insulating or heating effect. Thus, it is difficult for the sub DAB signal to penetrate such a windshield, and signal reception is greatly affected. The second type of DAB antenna is a roof mounted antenna that needs to be mounted on the roof of an automobile. This antenna has a high signal reception capability, but has the disadvantage that no holes are required for mounting the antenna on the roof of most of the vehicles shipped without roof antennas. Need punch in the installation to after the installation, still need do waterproof. If waterproofing is not done, rust may develop throughout the interior of the vehicle roof. Finally, the installation of such antennas is a rather complicated and time consuming process.

Disclosure of Invention

The utility model provides a not enough to prior art, the utility model provides a car antenna structure compares more beautifully than pasting the antenna on glass, and signal reception ability is stronger, compares with roof antenna, and its advantage is that the installation is simpler, and drilling is little, and it is waterproof easier to follow-up doing.

The technical scheme of the utility model is that: the utility model provides an automobile antenna structure, includes the antenna body, the antenna body totality is the straight line and extends, the circuit part of antenna body is located the middle part of antenna body, its characterized in that: the automobile license plate display device further comprises a first cover plate and a second cover plate, after the first cover plate and the second cover plate are connected, a cavity for containing an automobile license plate is formed in the middle of the first cover plate and the second cover plate, the first cover plate is further provided with a window for displaying the automobile license plate, the antenna body is fixedly installed between the first cover plate and the second cover plate, the second cover plate is further provided with a signal hole, and a circuit part of the antenna body is connected with an internal circuit of an automobile through the signal hole.

Further, the antenna body is a DAB antenna and is installed at the upper part between the first cover plate and the second cover plate.

Furthermore, the part of the first cover plate or the second cover plate covering the antenna body is made of plastic.

Furthermore, the first cover plate and the second cover plate are connected through screws, and a buckle for auxiliary connection is arranged between the two cover plates.

Further, the window for displaying the license plate on the first cover plate is a hollow window.

Further, the second cover plate is an automobile bumper.

Further, the second cover plate is an independent rear cover of a license plate of the automobile, and the second cover plate is fixedly arranged on the automobile.

The utility model has the advantages that: the automobile license plate and the DAB antenna are integrated, the structure is attractive, the wind resistance on the surface of the automobile is reduced, the automobile antenna structure which is simpler to install is provided for the automobile without the DAB antenna, the installation structure is small in drilling, subsequent waterproof is easier, and in addition, the antenna has stronger signal receiving capacity.

Detailed Description

As shown in fig. 1-2, an antenna structure for a vehicle comprises an antenna body 3, the antenna body 3 extends in a straight line, a circuit portion of the antenna body 3 is located in the middle of the antenna body 3, and further comprises a first cover plate 2 and a second cover plate 4, after the first cover plate 2 and the second cover plate 4 are connected, a cavity for accommodating a license plate of the vehicle is formed in the middle of the two, the first cover plate 2 further has a window for displaying the license plate of the vehicle, the antenna body 3 is fixedly installed between the first cover plate 2 and the second cover plate 4, the second cover plate 4 further has a signal hole, and the circuit portion of the antenna body 3 is connected with an internal circuit of the vehicle through the signal hole.

In a preferred embodiment, the antenna body 3 is a DAB antenna, and is installed on the upper portion between the first cover plate 2 and the second cover plate 4, preferably without being covered by a license plate, or a separate accommodating space is formed in a frame on the upper portion of the first cover plate 2 for isolating the antenna from the license plate.

In a preferred embodiment, the first cover plate 2 or the second cover plate 4 is made of a non-metal material, such as plastic, at least at a portion covering the antenna body 3, so that the antenna is not shielded, and the first cover plate 2 or the second cover plate 4 may also be made of a non-metal material as a whole.

In a preferred embodiment, the first cover plate 2 and the second cover plate 4 are connected by four screws 1, and a buckle for auxiliary connection is provided between the two cover plates, and the screws 1 can be anti-theft screws.
