Description

Technical Field

[0001] This application relates to the technical field of mobile antennas, and more particularly, to a three-axis antenna for a vehicle. Background Art

[0002] An antenna is a device that converts the interaction between electromagnetic fields and electric currents. The basic principle involves converting electrical energy into radio waves or converting radio waves into electrical energy. Antennas are widely used on vehicles to provide real-time signal communication between the vehicle and satellites.

[0003] In the prior art, on vehicles such as ships and airplanes that travel long distances, the antenna needs to adjust the orientation of the signal receiver in real time, quickly, and accurately so that the signal receiver faces the satellite directly and maintains a good signal connection with the satellite. Although the existing antennas can adjust the signal receiver at multiple angles, the adjustment speed is slow and the tracking ability for satellites is weak. For some airplanes and ships that perform high-precision navigation, their needs cannot be effectively met. At the same time, if the internal structure of the antenna is increased to increase the adjustment speed, the volume of the antenna will increase, which does not meet the development requirements of antennas that are becoming increasingly miniaturized.

[0004] Therefore, it is necessary for the inventor to design a new three-axis antenna for a vehicle to overcome the above problems. Summary of the Invention

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 4As shown in the figure, a three-axis antenna for a vehicle includes an installation bottom shell 1. A support frame 2 is rotatably arranged on the installation bottom shell 1. The support frame 2 is inclined. A first driving component is arranged between the support frame 2 and the installation bottom shell 1. The top end of the support frame 2 is rotatably connected to a U-shaped frame 3. A second driving component is arranged between the middle part of the U-shaped frame 3 and the support frame 2. A rotating plate 4 is rotatably arranged between the two side plates of the U-shaped frame 3. A third driving component is arranged between the rotating plate 4 and the U-shaped frame 3. A signal receiver 5 is rotatably arranged on the rotating plate 4. A fourth driving component is arranged between the signal receiver 5 and the rotating plate 4. During operation, the rotation of the support frame 2 can realize the rotation of the signal receiver 5 along the axis of the installation bottom shell 1. The rotation of the U-shaped frame 3 and the support frame 2 can realize the flipping swing of the signal receiver 5 to both sides of the support frame 2. The rotation of the rotating plate 4 can realize the flipping swing of the signal receiver 5 around the axis of the rotating plate 4. And the rotation of the signal receiver 5 on the rotating plate 4 can realize the rotation of the signal receiver 5 along its own axis to adjust its own posture. By setting the rotation of the support frame 2, the rotation of the U-shaped frame 3, and the rotation of the rotating plate 4, the signal receiver 5 can freely adjust the orientation of its central axis and point to satellites at any position in the sky. This three-axis adjustment method has a fast adjustment speed and strong tracking ability.

[0032] The first driving component includes a bottom plate 6 and a first gear 7. The support frame 22 is fixedly installed on the bottom plate 6. The bottom plate 6 is rotatably connected to the installation bottom shell 1. A first motor 8 is fixedly arranged on the bottom plate 6. The output end of the first motor 8 is fixedly connected to a second gear 9. The second gear 9 meshes with the first gear 7. During operation, when the first motor 8 is started, the first motor 8 drives the second gear 9 to rotate. The second gear 9 rolls on the outer circumference of the first gear 7 to realize the rotational adjustment of the bottom plate 6 and the support frame 2.

[0033] A rotating groove 10 is formed at the top of the support frame 2. The middle part of the U-shaped frame 3 is rotatably arranged on the side wall of the rotating groove 10. The rotation axis of the U-shaped frame 3 and the rotation axis of the support frame 2 are in the same plane. During operation, the middle part of the U-shaped frame 3 rotates in the rotating groove 10. The rotation axis of the U-shaped frame 3 and the rotation axis of the support frame 2 are in the same plane, making it simpler to control the rotation of the two through the chip program. The three-dimensional modeling of each component in the program setting is more accurate, and it is less likely to make mistakes when adjusting the positions of each component.

[0034] The second driving component includes a second motor 11 and a connecting shaft 12. The connecting shaft 12 is fixedly arranged on the U-shaped frame 3, and the second motor 11 is fixedly arranged on the support frame 2. A transmission component 24 for driving the U-shaped frame 3 to rotate is arranged between the output end of the second motor 11 and the connecting shaft 12. During operation, when the second motor 11 is started, the second motor 11 drives the U-shaped frame 3 to rotate through the transmission component 24, realizing the rotational adjustment of the U-shaped frame 3. It should be noted that the transmission component 24 here is not the core creative point of this case, and any structure that can achieve transmission between the support frame 2 and the U-shaped frame 3 can be applied here. For example Figure 3 as shown, the transmission is carried out by means of a transmission belt and belt pulleys.

[0035] The third driving component includes a third motor 13 and a sector gear 14. The sector gear 14 is fixedly connected to one end of the rotating plate 4. The third motor 13 is fixedly arranged on the U-shaped frame 3. The output end of the third motor 13 is fixedly connected with a third gear 15, and the third gear 15 meshes with the sector gear 14. During operation, when the third motor 13 is started, it drives the third gear 15 to rotate, and the third gear 15 drives the sector gear 14 to rotate, thereby driving the rotation of the rotating plate 4. Here, since the rotation range of the rotating plate 4 does not require a 360-degree rotation, the gear meshing with the third gear 15 does not need to have a 360-degree gear. Therefore, using the sector gear 14 can reduce the space occupied by the gear while meeting the rotation requirements, which is beneficial to the miniaturization of the antenna.

[0036] The fourth driving component includes a fourth gear 16 and a fourth motor 17. The fourth gear 16 is fixedly arranged on the rotating plate 4, and the signal receiver 5 is fixedly connected with the fourth gear 16. The fourth motor 17 is fixedly installed on the rotating plate 4, and the output end of the fourth motor 17 is fixedly connected with a fifth gear 18, and the fifth gear 18 meshes with the fourth gear 16. During operation, due to the rotation of the support frame 2, the rotation of the U-shaped frame 3, and the rotation of the rotating plate 4, and since the signal receiver 5 needs to be connected to the power supply and the chip through cables, it is also necessary to prevent the cables inside it from being wound and damaged during rotation. By starting the fourth motor 17 to drive the fifth gear 18 to rotate, the fifth gear 18 drives the fourth gear 16 to rotate, realizing the rotational adjustment of the signal receiver 5 itself, so that the signal receiver 5 can maintain the correct posture and avoid the winding of the internal cables.

[0037] A high-frequency head 19 and a power amplifier 20 are also fixedly installed on the rotating plate 4. The high-frequency head 19 and the power amplifier 20 are fixedly connected to the signal receiver 5 through a waveguide 21. During operation, the high-frequency head 19 and the signal receiver 5 cooperate to receive and transmit satellite signals.

[0038] The mounting base shell 1 is also fixedly connected to a cover shell 22, and the signal receiver 5 is located in an inner cavity formed by the mounting base shell 1 and the cover shell 22; it also includes a chip module 23, and the chip module 23 is fixedly connected to the mounting base shell 1; when working, the chip module 23 is electrically connected to the first motor 8, the second motor 11, the third motor 13, and the fourth motor 17, and the position of the signal receiver 5 in space is controlled by the program built into the chip module 23. It should be noted that the control method of the chip module 23 is not the core creation point of this case, and any control method that can achieve separate control of the four motors here can be applied here.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
