Description

Technical Field

[0001] This utility model relates to the field of satellite communication technology, specifically a satellite communication device based on the Tiantong satellite. Background Technology

[0002] As an important extension of terrestrial networks, satellite communication plays a key role in the "integrated air-space-ground-sea" communication system. China Telecom's Tiantong Satellite, as my country's independently controllable satellite mobile communication system, has demonstrated unique value in scenarios such as vehicle-mounted emergency communication, logistics fleet monitoring, and field exploration operations due to its wide coverage and strong resilience.

[0003] Traditional vehicle-mounted satellite communication devices mostly use fixed parabolic antennas or simple telescopic antennas. Their pointing angles rely on rough manual adjustments. During vehicle operation or in complex environments, satellite dishes are prone to signal attenuation or even interruption due to angle deviation. While some semi-automatic adjustment devices can adjust the angle, their mechanical linkage precision is insufficient, resulting in large pointing errors and making it difficult to maintain stable communication in weak signal scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a satellite communication device based on the Tiantong satellite to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a satellite communication device based on the Tiantong satellite, comprising a satellite dish and a vehicle-mounted platform. The vehicle-mounted platform is located on the roof of a vehicle. Two mounting seats are symmetrically installed on the upper end of the vehicle-mounted platform. Two mounting slots are symmetrically opened on the upper end of each mounting seat. A supporting triangular plate is rotatably connected inside each mounting slot. The two supporting triangular plates at the upper end of each mounting seat form a group. A rotating shaft is rotatably connected to the upper part of each group of supporting triangular plates. A mounting plate is installed at one end of the rotating shaft. A connecting plate is installed on the outer side of the two mounting plates. The connecting plate is connected to the side wall of the satellite dish.

[0006] Preferably, a reinforcing shaft is provided at the middle position of the two supporting triangular plates in the same group, and a supporting plate is installed between the two groups of supporting triangular plates.

[0007] Preferably, two connecting rods are symmetrically installed at the upper end of the front vehicle platform of the mounting base. An extension seat is installed at the front end of the two connecting rods. Two active telescopic rods are rotatably connected to the upper end of the extension seat. The upper ends of the two active telescopic rods are rotatably connected to the inner wall of a set of supporting triangular plates.

[0008] Preferably, a placement base is installed on the outer side of the front connecting rod of the mounting base, and a driven telescopic rod is rotatably connected to the upper end of the placement base. A linkage rod is installed between the two driven telescopic rods.

[0009] Preferably, both ends of the linkage rod are provided with extension rods that pass through the driven telescopic rod and extend outwards, and the surfaces of the two extension rods are rotatably connected with mounting blocks, and the front ends of the two mounting blocks are fixedly connected to the side wall of the satellite dish.

[0010] Preferably, the vehicle platform includes a fixed base and a rotating disk. The fixed base is fixedly installed on the top of the vehicle, and the rotating disk is rotatably connected inside the fixed base through a drive device. The upper end of the rotating disk is connected to the lower end of two mounting seats.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This satellite communication device based on the Tiantong satellite can rotate a support triangle plate around the rotation center of the mounting base when the vehicle is moving or parked. This rotation, via the rotating shaft, causes the mounting plate and connecting plate to tilt, ultimately achieving coordinated adjustment of the satellite dish's pitch and azimuth angles. When the vehicle is climbing a slope or turning, the active telescopic rod can dynamically adjust the tilt of the support triangle plate according to the road slope or turning angle, ensuring that the satellite dish always maintains the optimal alignment angle with the Tiantong satellite. In stationary scenarios, the pointing error of the satellite dish can be precisely controlled by finely adjusting the stroke of the active telescopic rod, significantly improving the communication success rate in weak signal environments. Through the design of active adjustment and external structural linkage, the device can adapt to various complex scenarios such as mountainous terrain, urban high-rise building obstruction, and high-speed driving, greatly expanding the applicability of vehicle-mounted satellite communication.

[0012] 2. This satellite communication device based on the Tiantong satellite of China Telecom constructs a support system with high rigidity and dynamic stability through the coordinated structure of supporting triangular plates, reinforcing shafts, driven telescopic rods, and vehicle-mounted platforms. The reinforcing shaft set in the middle of the two supporting triangular plates in the same group and the supporting plate below form a triangular rigid frame, which effectively suppresses the deformation of the supporting triangular plates during the extension and retraction process, ensuring the transmission accuracy of the rotating shaft and the connecting plate. In addition, the driven telescopic rod is connected to the side wall of the satellite dish through the linkage rod and the extension rod, which can provide reverse support force when the active telescopic rod is adjusted, avoiding the satellite dish from sagging or shifting due to its own weight or vehicle bumps.

[0017] like Figures 1 to 4As shown, this embodiment is a satellite communication device based on the Tiantong satellite, including a satellite dish 1 and a vehicle-mounted platform 3. The vehicle-mounted platform 3 is located on the roof of a vehicle and serves as the basic support component of the device, providing core support and connection. Two mounting seats 5 are symmetrically installed on the upper end of the vehicle-mounted platform 3. Two mounting slots 9 are symmetrically formed on the upper end of the mounting seats 5. The mounting seats 5 are symmetrically arranged on the upper end of the vehicle-mounted platform 3, and their internal mounting slots 9 provide rotation space for the supporting triangular plates 2, allowing the supporting triangular plates 2 to rotate around the rotation axis inside the slot. The supporting triangular plates 2 are rotatably connected inside each mounting slot 9. The two supporting triangular plates 2 on the upper end of each mounting seat 5 form a group, and there are two supporting triangular plates 2 in each group. The rigid support of the structure, the rotating shaft 17 and the upper components, allows the supporting triangular plate 2 to swing up and down around the rotating shaft in the mounting groove 9, directly driving the pitch angle change of the satellite dish 1. The upper part of each group of supporting triangular plates 2 is rotatably connected to the rotating shaft 17. One end of the rotating shaft 17 is equipped with a mounting plate 15. The outer sides of the two mounting plates 15 are jointly equipped with a connecting plate 4. The connecting plate 4 is connected to the side wall of the satellite dish 1. The rotating shaft 17 connects to the upper part of the two supporting triangular plates 2 in the same group. The mounting plate 15 at one end is used to fix the rotating shaft 17 and transmit torque. The connecting plate 4 on the outer side of the two mounting plates 15 is directly fixed to the side wall of the satellite dish 1, converting the swing of the supporting triangular plate 2 into the pitch angle adjustment of the satellite dish 1.

[0018] Specifically, a reinforcing shaft 14 is provided in the middle of the two supporting triangular plates 2 in the same group, and a supporting plate 16 is installed between the two groups of supporting triangular plates 2. The reinforcing shaft 14 can connect and reinforce the two supporting triangular plates 2 in the same group. The supporting plate 16 is X-shaped and located between the two groups of supporting triangular plates 2, providing a connection and reinforcement effect for the two groups of supporting triangular plates 2.

[0019] Furthermore, two connecting rods 6 are symmetrically installed on the upper part of the front vehicle platform 3 of the mounting base 5. The front ends of the two connecting rods 6 are jointly installed with an extension seat 7. The upper end of the extension seat 7 is rotatably connected to two active telescopic rods 8. The upper ends of the two active telescopic rods 8 are rotatably connected to the inner wall of a set of supporting triangular plates 2. The active telescopic rods 8 are electric telescopic rods connected to an external power source. The two active telescopic rods 8 on the same side can operate independently, driving the set of supporting triangular plates 2 to make adjustments.

[0020] Furthermore, a placement base 13 is installed on the outer side of the front connecting rod 6 of the mounting base 5. A driven telescopic rod 10 is rotatably connected to the upper end of the placement base 13. A linkage rod 12 is installed between the two driven telescopic rods 10. The core function of the driven telescopic rod 10 is to provide reverse support force to the outer side of the supporting triangle plate 2 to counteract the sagging torque generated by the satellite dish 1 due to its own weight or wind load. Both ends of the linkage rod 12 pass through the driven telescopic rods 10 and extend outward with extension rods 18. Mounting blocks 11 are rotatably connected to the surfaces of the two extension rods 18. The front ends of the two mounting blocks 11 are fixedly connected to the side wall of the satellite dish 1. The linkage rod 12 connects the two driven telescopic rods 10 so that the two driven telescopic rods 10 can perform synchronous telescopic movements.

[0021] Furthermore, the vehicle platform 3 includes a fixed base 301 and a rotating disk 302. The fixed base 301 is fixedly installed on the top of the vehicle. The rotating disk 302 is rotatably connected to the inside of the fixed base 301 via a drive device. The upper end of the rotating disk 302 is connected to the lower end of two mounting seats 5. The fixed base 301 is fixed to the vehicle roof by bolts or suction cups, forming the basic frame of the vehicle platform 3. Its material must be waterproof and rustproof, and its structural strength is enhanced by internal reinforcing ribs. The rotating disk 302 is installed inside the fixed base 301 and achieves horizontal rotation via a drive device, such as a conventional servo motor. Its surface is provided with anti-slip textures or ball bearings, and it is fixedly connected to the lower end of the mounting seats 5 to ensure that the mounting seats 5 rotate synchronously with the rotating disk 302.

[0022] The usage method of this embodiment is as follows: After the vehicle is started, the drive device inside the fixed base 301 controls the rotating disk 302 to rotate horizontally to compensate for the azimuth angle offset of the satellite dish 1 caused by changes in vehicle steering or driving route; if it is necessary to adjust the pitch angle of the satellite dish 1, the active telescopic rod 8 is extended and retracted to push the support triangle plate 2 to swing around the pivot of the mounting groove 9, which simultaneously drives the rotating shaft 17, mounting plate 15 and connecting disk 4 to tilt, so as to achieve the best alignment between the satellite dish 1 and the Tiantong satellite; the driven telescopic rod 10 cooperates with the extension rod through the linkage rod 12 to provide reverse support force for the support triangle plate 2, so as to prevent the satellite dish 1 from shifting due to its own weight or vehicle bumps.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
