Description

Technical Field

[0001] The utility model belongs to the technical field of command aircraft antennas, and in particular relates to an anti-interference antenna for a Beidou command aircraft. Background Art

[0002] The Beidou command machine is a special user machine designed by Beidou Starcom to facilitate group networking and dispatching command. In addition to the positioning, communication and timing functions of ordinary user machines, it can also monitor the positioning and communication information of subordinate user machines. The Beidou command machine anti-interference antenna is a highly integrated Beidou anti-interference antenna, which consists of array antenna, down-conversion channel, anti-interference baseband processing, up-conversion channel, combiner, clock generation and power conversion and other functional modules, which can realize anti-interference processing of Beidou-3 and Beidou-3 frequency bands.

[0003] The anti-interference antennas currently on the market have the following problems when used:

[0004] 1. When using traditional anti-interference antennas, the antenna body is usually directly fixed on the top of the mounting plate, and no additional protective structure is set on the outside of the antenna body. Therefore, when the anti-interference antenna is hit by the outside during use, it will cause different degrees of damage to the anti-interference antenna, and it is also more troublesome to repair it later. Therefore, the protective performance during use is poor;

[0005] 2. Most anti-interference antennas are often directly connected to the line during application. In the later use, once they are accidentally pulled by someone, the connection line is easy to loosen during application. Therefore, the power cord cannot be fixed well, so the fastening effect is not strong during application. Utility Model Content

[0029] In order to better understand the purpose, structure and function of the utility model, the anti-interference antenna of the Beidou command machine of the utility model is further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, the utility model of the Beidou command aircraft anti-interference antenna includes an antenna body 1 and a circular plate 2. The bottom of the antenna body 1 is fixedly connected to the circular plate 2, and the two sides of the circular plate 2 are fixedly connected to the second side plates 4. The second side plate 4 is connected to the first side plate 3 by a rotating shaft, and the inner side of the first side plate 3 is fixedly connected to the protective cover 5. Since the protective cover 5 is provided, it is convenient to protect the antenna body 1 on the top of the circular plate 2, and the protective effect is stronger when in use. A strip groove 7 is provided on the side of the protective cover 5, and a magnetic attraction plate 8 is embedded in the strip groove 7. A cavity 6 is provided in the protective cover 5. Since the strip groove 7 is provided and combined with the magnetic attraction plate 8, it is convenient to embed the magnetic attraction plate 8 in the strip groove 7, and then the protective covers 5 on both sides can be quickly adsorbed, which facilitates the closing of the protective cover 5.

[0031] The outside of the antenna body 1 is fixedly connected to a square plate 18, the inside of the square plate 18 is provided with an interface 13, the outside of the square plate 18 is sleeved with a shell 16, a limiting plate 17 is inserted into the inside of the shell 16, a connector 14 is embedded in the interface 13, and the limiting plate 17 is attached to the back of the connector 14. Since the shell 16 is provided and combined with the limiting plate 17, the interface 13 is conveniently protected. Secondly, the limiting plate 17 can fix the connector 14 to prevent it from falling off.

[0032] The protective cover 5 is symmetrically distributed, and a threading opening 20 is provided inside the protective cover 5. Due to the threading opening 20, it is convenient to pass the power line 15 on the back of the connector 14, so that the power line 15 can be connected while being protected.

[0033] A first card slot 10 and a second card slot 12 are provided inside the shell 16, and a first card block 9 and a second card block 11 are provided outside the square plate 18. The first card block 9 is inserted into the first card slot 10, and the second card block 11 is inserted into the second card slot 12. Due to the provision of the first card slot 10 and the combination of the first card block 9, the shell 16 is conveniently installed on the outside of the square plate 18, and the installation is relatively convenient.

[0034] A limiting groove 19 is provided on the top of the shell 16, and a limiting plate 17 is embedded in the limiting groove 19. Due to the limiting groove 19, the limiting plate 17 can move up and down in the limiting groove 19 inside the shell 16 more quickly.
