Abstract
Description
Technical Field
[0001] This invention relates to the field of satellite signal technology, specifically to an outdoor mobile communication satellite signal receiving device. Background Technology
[0002] A vehicle-mounted satellite signal receiver is a communication device integrated into a vehicle. It is usually installed in an open location such as the roof or rear of the vehicle. Its core consists of a satellite antenna, a signal tracking mechanism, a radio frequency processing unit, a power adapter module, and a mounting base. It captures satellite downlink signals and performs modulation, demodulation, signal amplification, and other processing. When a vehicle is in motion, the oncoming airflow directly impacts the antenna and mounting base of the existing vehicle-mounted satellite signal receiving device. This results in a significant increase in wind resistance at high speeds or in strong winds. Furthermore, the airflow easily forms eddies on the antenna surface, causing high-frequency jitter and compromising the alignment accuracy of the signal tracking mechanism. This leads to signal strength fluctuations and transmission interruptions. At the same time, the continuous load generated by the airflow impact concentrates on the base connection points, which can easily cause bolts to loosen, base deformation, and even excessive wear on components such as gears and bearings in the tracking mechanism, thus shortening the equipment's service life. Summary of the Invention
[0003] The purpose of this invention is to provide an outdoor mobile satellite signal receiving device to solve the problems in the prior art where, when a vehicle is in motion, the oncoming airflow directly acts on the antenna body and mounting base, resulting in a significant increase in wind resistance at high speeds or in strong winds. Furthermore, the airflow easily forms eddies on the antenna surface, causing high-frequency jitter, which damages the alignment accuracy of the signal tracking mechanism, leading to signal strength fluctuations and transmission interruptions. At the same time, the continuous load generated by the airflow impact is concentrated on the base connection parts, which can easily cause bolts to loosen, base deformation, and even excessive wear on components such as gears and bearings of the tracking mechanism, thus shortening the service life of the equipment.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an outdoor mobile satellite signal receiving device, including a turbulence component disposed on one side of the base plate, and an adjustment component disposed on one side of the base plate; The turbulence component includes two sets of sliding grooves, and the sliding grooves are both horizontally embedded with sliders. Support rods are fixedly connected to one side of the outer surface of the two sets of sliders, and guide plates are fixedly connected to one side of the outer surface of the multiple support rods. The adjustment assembly includes two sets of fixed plates, and a drive screw is rotatably embedded inside each of the two sets of fixed plates. The drive screw is connected to a threaded block through a ball nut pair. A transmission rod is rotatably embedded inside one of the two sets of fixed plates, and rotating blades are fixedly connected to both sides of the outer surface of the transmission rod.
[0005] Preferably, both sides of the outer surface of the threaded block are fixedly connected to movable plates, and the first connecting rod is rotatably embedded inside the multiple movable plates.
[0006] Preferably, the outer surfaces of both sets of first connecting rods are rotatably fitted with connecting arms, and the interiors of both sets of connecting arms are rotatably embedded with second connecting rods, with the ends of the two sets of second connecting rods away from the connecting arms located inside the slider.
[0007] Preferably, a limiting rod is fixedly connected to one side of the outer surface of both sets of fixing plates, and the threaded block is slidably sleeved on the outer surface of the limiting rod in a horizontal direction.
[0008] Preferably, a first bevel gear is rotatably embedded inside one group of the plurality of fixed plates, and a second bevel gear is rotatably embedded inside one group of the plurality of fixed plates.
[0009] Preferably, the outer surface of the first bevel gear meshes with the second bevel gear, and one side of the outer surface of the first bevel gear is fixedly connected to the drive screw.
[0010] Preferably, the outer surface of the rotating blade is wound with two sets of torsion springs.
[0011] Preferably, the second bevel gear is fixedly connected to the outer surface of the transmission rod.
[0012] Preferably, both sets of fixing plates are fixedly connected to the bottom of the outer surface of the base plate.
[0013] Preferably, both sets of the guide plates are made of high-strength aluminum alloy.
[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: First, during the movement of the satellite receiver device by the vehicle, the present invention has a base plate on the top of the vehicle and in front of the satellite receiver device. Two sets of guide plates slide inside the base plate. The two sets of guide plates are made of high-strength aluminum alloy, and the initial structure of the guide plates is triangular. The opening of the guide plates faces the satellite receiver device, and the apex of the triangle faces the direction of vehicle travel. During the movement of the vehicle, the oncoming airflow is quickly guided to both sides, avoiding direct impact of the airflow on the satellite receiver device body and the connection part with the vehicle. This avoids the impact from aggravating the loosening of the base bolts and structural wear. At the same time, it avoids the instantaneous impact of the airflow on the receiver device from causing antenna jitter, which would affect the stability of signal tracking accuracy. In rainy or snowy weather, the guide plates can guide rainwater and snowflakes to flow along both sides, preventing them from accumulating in the gaps where the receiver device is connected to the vehicle body, reducing the risk of short circuits and base corrosion caused by rainwater infiltration.
[0015] Secondly, during vehicle movement, the wind drives two sets of rotating blades to rotate. These blades, via a transmission rod, drive a second bevel gear. A torsion spring is installed outside the transmission rod, and both torsion springs reset when the vehicle stops. The rotation of the second bevel gear drives the meshing first bevel gear to rotate, which in turn drives a drive screw. This drive screw then moves a threaded block connected to a ball nut pair. The movement of the threaded block, via a connecting arm, causes a slider to slide within a groove. This sliding movement of the slider changes the angle of the two sets of guide vanes, thus adjusting their width. Through this technical solution, the opening width of the guide vanes is adjusted based on the vehicle's speed and the prevailing wind speed. At low wind speeds, the vanes open slightly to avoid wind resistance redundancy, while at high wind speeds, they open significantly to maximize the diversion effect. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] Please see Figures 1-4 An outdoor mobile satellite signal receiving device includes a turbulence component disposed on one side of a base plate 1 and an adjustment component disposed on one side of the base plate 1. The turbulence component includes two sets of sliding grooves 102, and the sliding sliders 4 are horizontally embedded inside the two sets of sliding grooves 102. Support rods 403 are fixedly connected to one side of the outer surface of the two sets of sliding sliders 4, and guide plates 2 are fixedly connected to one side of the outer surface of the multiple support rods 403. The adjustment assembly includes two sets of fixed plates 101, and a drive screw 3 is rotatably embedded inside each of the two sets of fixed plates 101. The drive screw 3 is connected to a threaded block 301 through a ball nut pair. A transmission rod 601 is rotatably embedded inside one of the two sets of fixed plates 101, and rotating blades 6 are fixedly connected to both sides of the outer surface of the transmission rod 601.
[0020] Through the above technical solution, during the movement of the satellite receiver driven by the vehicle, a base plate 1 is set on the top of the vehicle and in front of the satellite receiver. Two sets of guide plates 2 slide inside the base plate 1. The two sets of guide plates 2 are made of high-strength aluminum alloy, and the initial device of the guide plates 2 is triangular. The opening of the guide plates 2 faces the satellite receiver, and the tip of the triangle faces the direction of vehicle travel. During the vehicle's movement, the oncoming airflow is quickly guided to both sides, avoiding direct impact of the airflow on the satellite receiver body and the connection parts with the vehicle. This prevents the impact from aggravating the loosening of the base bolts and structural wear. At the same time, it avoids the instantaneous impact of the airflow on the receiver causing antenna jitter, which would affect the stability of signal tracking accuracy. In rainy or snowy weather, the guide plates 2 can guide rainwater and snowflakes to flow along both sides, preventing them from accumulating in the gaps where the receiver bottom connects to the vehicle body, reducing the risk of short circuits and base corrosion caused by rainwater infiltration.
[0021] Through the above technical solution, during the vehicle's movement, the wind blows two sets of rotating blades 6 to rotate. The two sets of rotating blades 6 drive the second bevel gear 501 to rotate via the transmission rod 601. A torsion spring 602 is provided outside the transmission rod 601. The two sets of torsion springs 602 reset when the vehicle stops. The rotation of the second bevel gear 501 drives the meshing first bevel gear 5 to rotate. The rotation of the first bevel gear 5 drives the drive screw 3 to rotate. The rotation of the drive screw 3 drives the threaded block 301 connected to the ball nut pair to move. The movement of the threaded block 301 drives the slider 4 to slide in the slide groove 102 via the connecting arm 402. The sliding of the slider 4 causes the angle of the two sets of guide vanes 2 to change, thereby adjusting the amplitude of the two sets of guide vanes 2. Through the above technical solution, the opening amplitude of the guide vanes 2 can be adjusted according to the vehicle's driving speed and the wind force at that time. At low wind speeds, the vanes open slightly to avoid wind resistance redundancy, and at high wind speeds, they open significantly to maximize the diversion effect.
[0022] Specifically, both sides of the outer surface of the threaded block 301 are fixedly connected to movable plates 303, and the first connecting rod 304 is rotatably embedded inside the multiple movable plates 303.
[0023] Through the above technical solution, the threaded block 301 moves the first connecting rod 304 via the moving plate 303.
[0024] Specifically, the outer surfaces of the two sets of first connecting rods 304 are rotatably fitted with connecting arms 402, and the interiors of the two sets of connecting arms 402 are rotatably embedded with second connecting rods 401. The ends of the two sets of second connecting rods 401 away from the connecting arms 402 are located inside the slider 4.
[0025] Through the above technical solution, the first connecting rod 304 drives the slider 4 to move through the connecting arm 402 and the second connecting rod 401.
[0026] Specifically, a limit rod 302 is fixedly connected to one side of the outer surface of both sets of fixing plates 101, and the threaded block 301 is slidably sleeved on the outer surface of the limit rod 302 in a horizontal direction.
[0027] The above technical solution limits the threaded block 301 by using the limiting rod 302.
[0028] Specifically, a first bevel gear 5 is rotatably embedded inside one group of the multiple fixed plates 101, and a second bevel gear 501 is rotatably embedded inside one group of the multiple fixed plates 101.
[0029] With the above technical solution, both the first bevel gear 5 and the second bevel gear 501 are set inside the fixed plate 101.
[0030] Specifically, the outer surface of the first bevel gear 5 meshes with the second bevel gear 501, and one side of the outer surface of the first bevel gear 5 is fixedly connected to the drive screw 3.
[0031] Through the above technical solution, the rotation of the second bevel gear 501 drives the meshing first bevel gear 5 to rotate, and the rotation of the first bevel gear 5 drives the drive screw 3 to rotate.
[0032] Specifically, two sets of torsion springs 602 are wound around the outer surface of the rotating blade 6.
[0033] The above technical solution uses two sets of torsion springs 602 to reset when the vehicle stops.
[0034] Specifically, the second bevel gear 501 is fixedly connected to the outer surface of the transmission rod 601.
[0035] Through the above technical solution, the two sets of rotating blades 6 drive the second bevel gear 501 to rotate via the transmission rod 601.
[0036] Specifically, both sets of fixing plates 101 are fixedly connected to the bottom of the outer surface of the base plate 1.
[0037] Through the above technical solution, the fixing plate 101 is fixed to the bottom of the base plate 1.
[0038] Specifically, both sets of guide vanes 2 are made of high-strength aluminum alloy.
[0039] The above technical solution guides the flow through the guide plate 2.
[0040] During use, as the vehicle moves the satellite receiver, a base plate 1 is installed on the top of the vehicle and in front of the satellite receiver. Two sets of deflector plates 2 slide inside the base plate 1. The two sets of deflector plates 2 are made of high-strength aluminum alloy, and the initial shape of the deflector plates 2 is triangular. The opening of the deflector plates 2 faces the satellite receiver, and the apex of the triangle faces the direction of vehicle travel. During the vehicle's movement, the deflector plates quickly guide the oncoming airflow to both sides, preventing the airflow from directly impacting the satellite receiver and the connection parts with the vehicle. This avoids the impact from aggravating the loosening of the base bolts and structural wear. At the same time, it prevents the instantaneous impact of the airflow on the receiver from causing antenna jitter, which would affect the stability of signal tracking accuracy. In rainy or snowy weather, the deflector plates 2 can guide rainwater and snowflakes to flow along both sides, preventing them from accumulating in the gaps where the receiver is connected to the vehicle body, reducing the risk of short circuits and base corrosion caused by rainwater infiltration. During vehicle movement, wind forces two sets of rotating blades 6 to rotate. These blades, via a transmission rod 601, drive a second bevel gear 501 to rotate. A torsion spring 602 is installed outside the transmission rod 601. When the vehicle stops, the two torsion springs 602 reset. The rotation of the second bevel gear 501 drives the meshing first bevel gear 5 to rotate. The rotation of the first bevel gear 5 drives a drive screw 3 to rotate. The drive screw 3 then moves a threaded block 301 connected to a ball nut pair. This movement of the threaded block 301, via a connecting arm 402, causes a slider 4 to slide within a groove 102. The sliding of the slider 4 changes the angle of the two sets of guide vanes 2, thus adjusting their width. This technical solution adjusts the opening width of the guide vanes 2 based on the vehicle's speed and the prevailing wind force. At low wind speeds, the vanes open slightly to avoid wind resistance redundancy; at high wind speeds, they open significantly to maximize the diversion effect.
