[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an anti-interference Beidou vehicle-mounted antenna, comprising a mounting platform 1 fixed on the top of a car, a base 2 is mounted on the upper side of the mounting platform 1, an antenna body 10 is rotatably mounted on the base 2, an anti-collision plate 13 is mounted on one side of the antenna body 10, a suction cup 7 is fixed on the lower side of the base 2, a mounting groove 3 is opened in the base 2, a mounting block 4 is fixed on the mounting platform 1, the mounting block 4 corresponds to the mounting groove 3, a signal line 8 is mounted at one end of the base 2, and a magnetic ring 9 is mounted on the signal line 8.

[0022] In this embodiment, the mounting platform 1 is welded to the car, the top of the mounting platform 1 is a planar structure, a card slot 6 is opened in the mounting groove 3, and an elastic card block 5 is fixed to the peripheral side of the mounting block 4, and the elastic card block 5 corresponds to the card slot 6.

[0023] Specifically, when the device needs to be installed, the mounting platform 1 is welded and fixed to the roof, and then the mounting block 4 is inserted into the mounting groove 3, so that the suction cup 7 is adsorbed and fixed on the mounting platform 1. At this time, the elastic card block 5 enters the card groove 6, and the mounting block 4 can be installed, thereby ensuring the fixing strength and preventing the device from falling.

[0024] A groove 11 is formed on the base 2 , and a rotating shaft 12 is rotatably fitted in the groove 11 . The rotating shaft 12 is fixedly connected to the signal line 8 , and a torsion spring is fixed between the rotating shaft 12 and the groove wall of the groove 11 .

[0025] Specifically, when the car is driving, the antenna body 10 is subject to greater wind resistance. At this time, the antenna body 10 is blown, thereby driving the antenna body 10 to rotate. The antenna body 10 rotates in the groove 11 through the rotating shaft 12, which can prevent the antenna body 10 from breaking. When the car stops, under the action of the torsion spring, the rotating shaft 12 drives the antenna body 10 to reset, thereby ensuring signal reception.

The antenna body 10 is a telescopic structure, and the magnetic ring 9 is sleeved on one end of the signal line 8 close to the base 2. The signal line 8 is electrically connected to the antenna body 10 and the car.

[0027] Specifically, the anti-interference shielding layer 15 and the magnetic ring 9 can achieve a good anti-interference effect, thereby ensuring the reception and transmission of Beidou signals and ensuring that the antenna body 10 can be used normally. The anti-collision plate 13 can also protect the antenna body 10 to prevent the antenna body 10 from being damaged.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
