Description

Technical Field

[0001] The utility model relates to an arrangement structure of a shark fin antenna. Background Art

[0002] The Tiantong-1 satellite mobile communication system is a satellite mobile communication system independently developed and constructed by my country. Together with the ground mobile communication system, it forms a space-ground integrated mobile communication network. It has now covered all of China without any blind spots, and is not affected by factors such as terrain. It can achieve seamless coverage of oceans, mountainous areas, and plateaus from top to bottom. Satellite phones are a type of communication equipment based on satellite communication technology that uses satellite networks deployed on the earth to achieve remote communications. Unlike traditional mobile phone networks that rely on ground base stations, satellite phones communicate directly with ground stations through satellites, thereby providing communication services when there is no ground communication infrastructure or when the communication infrastructure is damaged.

[0003] In recent years, with the rapid development of the automobile industry, my country has become the world's largest automobile market, and automobile safety and passenger safety issues have become increasingly important. Currently, most mobile satellite communication systems on the market are handheld devices or portable satellite terminals. When a car accident occurs and there is no ground mobile communication network coverage, how to provide passengers with reliable and effective communication methods has become an urgent problem for major OEMs.

[0004] Competition in the domestic automobile industry is becoming increasingly fierce. How to reduce the cost of purchasing parts has become a key research topic for OEMs. Therefore, the integration and miniaturization of vehicle-mounted antennas will become an important development direction to meet the needs of OEMs.

[0005] Shark fin antenna is a commonly used component in vehicles. The AMFM antenna in conventional shark fin antenna is usually in the form of spring or PCB. The spring antenna has excellent function, but the material and labor costs are high. The conventional PCB antenna is arranged at the tail end of the shark fin antenna. It has low cost, but seriously occupies the internal space of the shark fin, and due to the limitation of the signal receiving area, it has poor function. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a shark fin antenna arrangement structure. The specific scheme includes:

[0007] A shark fin antenna arrangement structure comprises an antenna housing, a PCB board, an AM / FM antenna, a 5G antenna, and a Tiantong antenna, wherein the PCB board is fixed on the antenna housing, the AM / FM antenna is fixed on the front end of the antenna housing and arranged toward the cavity of the antenna housing, the Tiantong antenna is fixed on the rear end of the antenna housing, the 5G antenna is arranged between the AM / FM antenna and the Tiantong antenna, the AM / FM antenna, the 5G antenna, and the Tiantong antenna are electrically connected to the PCB board, and the PCB board is electrically connected with a signal output line.

[0008] Furthermore, the antenna housing includes a main shell and an end cover, and the main shell and the end cover are fixed by a first screw.

[0009] Furthermore, a sealing ring is provided between the main shell and the end cover.

[0010] Furthermore, the PCB board is fixed on the end cover by a second screw.

[0011] Furthermore, the AM / FM antenna, 5G antenna, and Tiantong antenna are electrically connected to the PCB board by welding.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model fully utilizes the space on the top of the shark fin to realize an antenna arrangement scheme with integrated antenna functions, miniaturization and low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 This is a schematic diagram of the layout structure of the shark fin antenna of the utility model;

[0016] Figure 3 This is another exploded schematic diagram of the arrangement structure of the shark fin antenna of the utility model. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3An embodiment of the utility model provides an arrangement structure of a shark fin antenna, including an antenna housing 1, a PCB board 2, an AM / FM antenna 3, a 5G antenna 4, and a Tiantong antenna 5. The PCB board 2 is fixed on the antenna housing 1, the AM / FM antenna 3 is fixed at the front end of the antenna housing 1 and arranged toward the cavity of the antenna housing 1, the Tiantong antenna 5 is fixed at the rear end of the antenna housing 1, the 5G antenna 4 is arranged between the AM / FM antenna 3 and the Tiantong antenna 5, the AM / FM antenna 3, the 5G antenna 4, and the Tiantong antenna 5 are electrically connected to the PCB board 2, and the PCB board 2 is electrically connected with a signal output line 6.

[0019] The AM / FM antenna layout can maximize the antenna height and signal receiving area in the limited antenna cavity space. The utility model makes full use of the space on the top of the shark fin. At the same time, because the operating frequency of the AM / FM antenna is very different from the 5G and Tiantong antennas below, the antenna signals will not interfere with each other. After receiving the corresponding signal, each antenna amplifies the signal through the PCB motherboard, and then the signal output line outputs the received signal to the corresponding terminal installed inside the vehicle.

[0020] As a further solution of the present invention: the antenna housing 1 comprises a main housing 11 and an end cover 12, and the main housing 11 and the end cover 12 are fixed by a first screw 13. This allows the antenna housing to be disassembled for easy maintenance.

[0021] As a further solution of the present invention: a sealing ring 14 is provided between the main housing 11 and the end cover 12, so that the antenna body and the vehicle body after the antenna is installed can meet the protection requirements of IP67 or above.

[0022] As a further solution of the present invention: the PCB board 2 is fixed to the end cover 12 by a second screw 7 .

[0023] As a further solution of the utility model: the signal output line 6 is welded on the PCB board 2, and the end cover 12 is installed with a mounting seat 81 and a buckle 82 through a threaded column 9. When an appropriate torque is applied to the threaded column 9, the four claws of the mounting seat will be forced to open outward until they support the car skin, thereby ensuring that the antenna is fixed to the car body. The function of the buckle is: when the antenna is installed, the antenna can be pre-fixed in the hole of the roof sheet metal to prevent the antenna from being pushed out of the hole when the bolt 9 is tightened in the car.

[0024] As a further solution of the present invention: the AM / FM antenna 3, the 5G antenna 4, and the Tiantong antenna 5 are electrically connected to the PCB board 2 by welding.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
