Mobile platform stable tracking satellite antenna is a device used to achieve stable reception and tracking of satellite signals on mobile carriers (such as cars, trains, ships, etc.).

[0003] In the prior art, satellite antennas installed on mobile platforms, such as satellite antennas installed on cars, will have an impact on the installed satellite antenna due to airflow generated on the roof of the car when the car is driving, causing the installation position of the satellite antenna to shake due to the influence of wind, and affecting the adjustment angle of the antenna, resulting in poor signal reception effect of the satellite antenna. For this reason, we propose a mobile platform for stably tracking satellite antennas to solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that airflow is generated on the roof of a vehicle, which affects the installed satellite antenna, causing the installation position of the satellite antenna to shake due to wind force, and affecting the adjustment angle of the antenna, resulting in poor signal reception effect of the satellite antenna, and a mobile platform is proposed to stably track the satellite antenna.

[0015] Compared with the prior art, the present invention provides a mobile platform for stably tracking satellite antennas, which has the following beneficial effects: 1. This mobile platform stably tracks the satellite antenna. By setting two symmetrical guide plates, the wind generated in the direction of vehicle travel can be blocked to prevent the wind generated at a high speed from directly blowing to the satellite antenna body and affecting it. According to the needs of vehicle travel, the guide plates can be rotated and adjusted to optimize the wind flow guidance and reduce the impact of wind resistance.

[0016] 2. This mobile platform stably tracks the satellite antenna.

[0024] Reference Figure 1-Figure 8A mobile platform for stably tracking a satellite antenna comprises a mobile platform mounting plate 1, a satellite antenna body 11 is mounted on the bottom of the mobile platform mounting plate 1, a guide plate 2 is symmetrically arranged on one side of the satellite antenna body 11, and when the guide plate 2 is rotated and adjusted, it is used to optimize the guidance of wind flow to the satellite antenna body 11; a reflector 3 is mounted on one side surface of the two guide plates 2, and is in a triangular shape, and is used for refracting and transmitting signals transmitted by the satellite antenna body 11; a diversion part is arranged on the guide plate 2, and the generated wind flow is diverted when the mobile platform is walking normally.

[0025] When in use, the mobile platform mounting plate 1 is installed at the bottom of the mobile platform, for example, the mobile platform mounting plate 1 is fixedly installed on the top of the car by bolts. When the vehicle is driving, airflow is generated on the top of the car. Two symmetrical deflectors 2 are arranged on one side of the satellite antenna body 11 in the direction of travel of the vehicle, so as to block the airflow blowing toward the satellite antenna body 11, and avoid the shaking of the satellite antenna body 11 caused by excessive wind speed, or affect the angle adjustment position of the satellite antenna body 11, thereby improving the working stability of the satellite antenna body 11 when the mobile platform is running, and avoiding the influence of wind speed. The leeward side of the deflector 2 is provided with a reflector 3. When the satellite antenna body 11 is working and facing the forward direction of the mobile platform, the reflector 3 is provided. The signal of the satellite antenna body 11 can be refracted, so as not to affect the reception of normal working signals of the satellite antenna body 11, and at the same time, it does not affect the blocking of the airflow by the guide plate 2. During the movement of the mobile platform, due to the fast speed, the blocking component on one side of the satellite antenna body 11 will be affected by the wind resistance. By rotating the position between the two guide plates 2, the wind flow guidance is optimized and the influence of the wind resistance phenomenon is reduced. By arranging a guiding part on the guide plate 2, during the driving of the vehicle, the guided airflow is refined and guided, so that the windflow can bypass the antenna more smoothly, further reducing the influence of wind resistance on the antenna, and part of the airflow can be intercepted and blown to the satellite antenna body 11 to dissipate heat and cool the satellite antenna body 11, wherein the reflector 3 is made of carbon fiber composite material.

[0026] In a preferred embodiment, referring to Figure 4 , Figure 5 and Figure 6, one side of the two guide plates 2 is rotatably connected with a connecting rod 25 through a pin shaft, one end of the connecting rod 25 is rotatably connected with a threaded block 23 through a pin shaft, the surfaces of the two threaded blocks 23 are threadedly connected with a bidirectional screw rod 21, the end of the bidirectional screw rod 21 is rotatably connected with the mobile platform mounting plate 1 through a bearing, an opening 24 is provided on the top surface of the mobile platform mounting plate 1, the threaded block 23 is slidably connected in the opening 24, one end of the bidirectional screw rod 21 is fixedly connected with a driving part 22, the driving part 22 is installed on one side surface of the mobile platform mounting plate 1, a fixed shaft 26 is embedded and installed on the top of the mobile platform mounting plate 1, and one end of the two guide plates 2 is rotatably connected with the fixed shaft 26 through a bearing; The driving part 22 is replaced by a private motor drive. When the position of the guide plate 2 needs to be adjusted, the driving part 22 is started to drive the bidirectional screw 21 to rotate, and the bidirectional screw 21 drives the two threaded blocks 23 to move in relative or opposite directions. Under the linkage of the connecting rod 25, the guide plates 2 are driven to run synchronously, thereby realizing the position adjustment of the two guide plates 2. With such a structural design, the guide plates 2 can not only block the airflow, but also reduce the generation of wind resistance, thereby improving the stability of the installation and placement of the guide plates 2.

[0027] In a preferred embodiment, referring to Figure 3 , Figure 5 and Figure 7 A connecting cylinder 42 is fixedly installed on one side of the two threaded blocks 23, a piston 43 is slidably connected inside the connecting cylinder 42, a sliding rod 41 is fixed on one side of the piston 43, and the end of the sliding rod 41 is fixedly connected to the inner wall of the mobile platform mounting plate 1, and one end of the connecting cylinder 42 is connected to a gas delivery member, which includes an air inlet pipe 44 fixed to one end of the connecting cylinder 42, and a one-way valve 45 is arranged on the air inlet pipe 44. An air delivery pipe 46 is fixedly connected to the end of the connecting cylinder 42, and an air delivery channel 47 is opened inside the fixed shaft 26, and the air delivery channel 47 at one end of the air delivery pipe 46 is connected, and an injection member is installed on the top of the fixed shaft 26, and the injection member includes a connecting plate 48 fixed to the top of the fixed shaft 26 through a hose, and the connecting plate 48 is installed on the top surface of the guide plate 2, and the bottom of the connecting plate 48 is provided with injection heads 49 distributed at equal intervals; When the two threaded blocks 23 move in opposite directions, the piston 43 in the connecting cylinder 42 can be driven to slide inside the connecting cylinder 42, so that the air in the connecting cylinder 42 is squeezed and transported, and then transported through the air pipe 46, and finally ejected through multiple nozzles 49. Since the nozzles 49 are set at an inclined angle, the reflector 3 installed on one side of the guide plate 2 can be blown to clean the dust and foreign matter attached to the surface of the reflector 3, thereby improving the refraction effect of the reflector 3 and ensuring the stability of the signal transmission of the satellite antenna body 11. Combined with the above-mentioned scheme, the guide plate 2 has the effect of assisting in cleaning the reflector 3 during the adjustment process.

[0028] In a preferred embodiment, referring to Figure 8 The diversion part includes a ventilation hole 51 opened on the upper surface of the guide plate 2, a sound absorbing plate 52 is installed inside the ventilation hole 51, and a diversion support frame 53 is fixed to the inner wall of the sound absorbing plate 52. A guide groove 54 is opened on one side of the guide plate 2, a square hole 6 is opened inside the mobile platform mounting plate 1, and the opening 24 is connected to the square hole 6. The surface of the mobile platform mounting plate 1 is opened with symmetrically distributed mounting holes 7, and the bottoms of the two guide plates 2 are slidably connected to the surface of the mobile platform mounting plate 1.

[0029] During the movement of the mobile platform, the satellite antenna body 11 will emit heat due to its long-term operation. Although there is a heat dissipation mechanism to conduct the heat, it is easy to accumulate dust when exposed to the external environment, which affects the heat dissipation effect. Through the set ventilation holes 51, a part of the airflow can be intercepted and blown to the satellite antenna body 11 through the ventilation holes 51, thereby accelerating the heat dissipation of the satellite antenna body 11. Through the setting of the diversion support frame 53, the airflow passing through the ventilation holes 51 is evenly dispersed, so that the airflow passes smoothly. The sound absorbing plate 52 is cylindrical in shape, which can absorb and reduce the noise generated by the passing airflow. When the airflow passes through the ventilation holes 51, it is mixed with the airflow blown out by the nozzle 49, and the direction is changed to blow toward the reflecting plate 3, thereby improving the cleaning effect of the nozzle 49. The square hole 6 is convenient for drainage.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
