Description

Technical Field

[0001] This utility model belongs to the field of communication performance testing technology, and relates to a vehicle-mounted wireless communication performance testing device, particularly a vehicle-mounted wireless communication performance testing device for low-orbit satellite payloads. Background Technology

[0002] In recent years, a new wave of space economy enthusiasm has emerged around low-Earth orbit (LEO) satellite internet constellations. Driven by demand and market forces, well-known international companies such as Iridium, OneWeb, and SpaceX have successively launched a series of mass-produced LEO communication constellation projects. LEO internet satellites, represented by Iridium-Next and OneWeb, adopt a trapezoidal configuration and modular design, with the satellite divided into payload modules and platforms for parallel assembly to meet mass production requirements. The +Z and +X panels constitute the payload modules, with large phased array user antennas, telemetry and control antennas, inter-satellite link antennas, and other equipment installed on the +Z panel, and feed antennas and other equipment installed on the +X panel.

[0003] A search revealed a Chinese patent document disclosing a performance testing platform for satellite communication terminals [Application No.: 202323387890.X; Publication No.: CN 221728330 U]. This performance testing platform for satellite communication terminals includes a testing component on its upper part, and a material gripping component installed on the upper part of the testing platform corresponding to the position of the testing component. The testing component includes a rotating frame installed in the middle of the upper part of the testing platform, a rotating disk rotatably connected to the upper part of the rotating frame, and workpiece seats equidistantly installed around the outer circumference of the rotating disk. A detection camera is installed on the upper part of the testing platform near the workpiece seat, and a fixing frame is provided between the inner sides of two detection cameras. A hydraulic rod is fixedly installed on the top of the fixing frame, and a pressure head is installed on the output shaft of the hydraulic rod. This utility model's performance testing platform for satellite communication terminals enables automatic loading and unloading testing of the entire device, effectively improving the work efficiency of users, enhancing the practicality of the overall device, and bringing better application prospects.

[0004] While this patent enables the entire device to achieve automatic loading and unloading detection, effectively improving the work efficiency of users, enhancing the practicality of the entire device, and bringing better application prospects, in the process of time-based communication performance detection, the signal detection device is usually installed in different locations to achieve the detection of wireless communication network performance. The existing signal detection device has a relatively complex installation method, which reduces its installation efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vehicle-mounted wireless communication performance testing device for low-orbit satellite payloads. The technical problem this invention aims to solve is: how to improve the installation efficiency of the testing device and make corresponding adjustments based on the model size of the communication signal detector to improve adaptability.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A vehicle-mounted wireless communication performance testing device for a low-orbit satellite payload includes a mounting base plate, a first limiting plate slidably connected to one side of the mounting base plate, and a second limiting plate slidably connected to the other side of the mounting base plate. A communication signal detector is placed on the mounting base plate, and an encapsulation top plate is rotatably connected to the top of the first limiting plate. A limiting component is provided at the top of the second limiting plate, and one end of the encapsulation top plate engages with the limiting component for limiting. A control component for controlling the movement of the first and second limiting plates is provided inside the mounting base plate. Multiple screw holes are provided on the first, second, and encapsulation top plates, and a limiting bolt is threaded into each screw hole. An extrusion block is provided on each limiting bolt, and each extrusion block engages with the outer wall of the communication signal detector for extrusion.

[0008] The working principle of this utility model is as follows: the distance between the first limiting plate and the second limiting plate is controlled by the regulating component, and adjusted accordingly according to the model and size of the communication signal detector. The limiting component controls the limiting state of the top plate of the package, thereby achieving the fixed limiting capability of the communication signal detector and further realizing the ability to quickly disassemble and assemble the communication signal detector, which facilitates the replacement and maintenance of the communication signal detector. The communication signal detector is pressed by multiple limiting screws in different positions, which further improves the fixing effect of the communication signal detector. Furthermore, the damage to the communication signal detector during the pressing process is reduced by squeezing the rubber block.

[0009] The encapsulation top plate includes a top plate one and a top plate two. The top plate one is rotatably connected to the top end of the limiting plate one. The top plate two cooperates with the limiting component. An extension plate is fixed on the top plate one. An extension groove is opened in the top plate two. The extension groove is slidably connected to the extension plate. A return spring is fixed between the extension plate and the groove wall of the extension groove.

[0010] With the above structure, the distance between top plate one and top plate two can be adjusted through the sliding fit between the extension plate and the extension groove, so that the length of the encapsulation top plate can be matched according to the distance between limit plate one and limit plate two, thereby improving the stability of use.

[0011] The limiting assembly includes a pair of limiting blocks fixed to the top of the limiting plate two, and a bidirectional screw rotatably connected inside the limiting plate two. A pair of limiting rings are fixed to one end of the top plate two, and the two limiting rings engage with the corresponding limiting blocks. A pair of limiting inserts are slidably connected inside the limiting plate two, and each limiting insert engages with the corresponding limiting ring. The threaded sections on both sides of the bidirectional screw are threadedly connected to the corresponding limiting inserts. A transmission worm gear is coaxially fixedly connected to the bidirectional screw, and a transmission worm is rotatably connected inside the limiting plate two. The transmission worm gear meshes with the transmission worm. An internal hexagonal nut two is provided on the limiting plate two, and the internal hexagonal nut two is coaxially fixedly connected to the transmission worm.

[0012] With the above structure, the transmission worm can be rotated by the internal hex nut, which in turn drives the transmission worm wheel to rotate. The worm wheel then drives the bidirectional screw to rotate, which in turn drives the two limit blocks to push out, completing the insertion and engagement with the corresponding limit rings.

[0013] The control assembly includes a bidirectional lead screw rotatably connected to the mounting base plate and a first transmission bevel gear rotatably connected to the mounting base plate. The first transmission bevel gear is coaxially fixedly connected to the bidirectional lead screw. A second transmission bevel gear is rotatably connected to the mounting base plate. The first transmission bevel gear meshes with the second transmission bevel gear. An internal hexagonal nut is provided on the mounting base plate. The first internal hexagonal nut is coaxially fixedly connected to the second transmission bevel gear. The first limiting plate and the second limiting plate are threadedly connected to the corresponding threaded sections of the bidirectional lead screw.

[0014] With the above structure, the transmission bevel gear 2 can be rotated by the internal hex nut 1, which in turn drives the transmission bevel gear 1 to rotate. After the transmission bevel gear 1 rotates, it will drive the double-acting screw to rotate. After the double-acting screw rotates, it will drive the limiting plate 1 and the limiting plate 2 to move in opposite directions or in opposite directions, thereby realizing the clamping action.

[0015] Each of the limiting bolts has a guide groove, and each guide groove has a guide block slidably connected to it. Each guide block is fixed with a push spring between it and the bottom of the corresponding guide groove, and each guide block is fixedly connected with a corresponding extrusion block.

[0016] With the above structure, the guide block can be pushed by the push spring, and the guide block can further squeeze and compress the rubber block, so that the rubber block contacts and limits the concave and convex structure of the communication signal detector housing, thereby improving the stability of the communication signal detector. Furthermore, the squeezing and limiting force can be adjusted by rotating the limiting bolt and adjusting the degree of screwing in the limiting bolt.

[0017] Compared with existing technologies, the vehicle-mounted wireless communication performance testing device for this low-orbit satellite payload has the following advantages:

[0018] 1. The distance between limit plate one and limit plate two is controlled by the adjustment component, and the corresponding adjustment is made according to the model and size of the communication signal detector. The limit component controls the limit state of the top plate of the package, so as to realize the fixed limit capability of the communication signal detector, and further realize the quick disassembly and assembly capability of the communication signal detector, so as to facilitate the replacement and maintenance of the communication signal detector.

[0019] 2. By pushing the guide block with the push spring, the guide block further squeezes and compresses the rubber block, so that the rubber block contacts and limits the concave and convex structure of the communication signal detector housing, thereby improving the stability of the communication signal detector. Furthermore, by rotating the limiting bolt, the squeezing and limiting force can be adjusted by the degree of screwing in the limiting bolt. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figures 1-5As shown, a vehicle-mounted wireless communication performance testing device for a low-orbit satellite payload includes a mounting base plate 1, a limiting plate 2 slidably connected to one side of the mounting base plate 1, and a limiting plate 3 slidably connected to the other side of the mounting base plate 1. A communication signal detector 4 is placed on the mounting base plate 1, and an encapsulation top plate 5 is rotatably connected to the top of the limiting plate 2. A limiting component is provided at the top of the limiting plate 3, and one end of the encapsulation top plate 5 is limited in fit with the limiting component. An adjustment component for controlling the movement of the limiting plates 2 and 3 is provided inside the mounting base plate 1. Multiple screw holes 6 are provided on the limiting plates 2, 3, and 5, and a limiting bolt 7 is threaded into each screw hole 6. An extrusion block 8 is provided on each limiting bolt 7, and each extrusion block 8 is extruded in fit with the outer wall of the communication signal detector.

[0028] The distance between the first limiting plate 2 and the second limiting plate 3 is then controlled by the regulating component, and adjusted accordingly based on the model and size of the communication signal detector 4. The limiting component controls the limiting state of the top plate 5, thereby achieving the fixed limiting capability of the communication signal detector 4 and further enabling the rapid disassembly and assembly of the communication signal detector 4, facilitating its replacement and maintenance. Multiple limiting screws press the communication signal detector 4 from different positions, further improving the fixing effect of the communication signal detector 4. Furthermore, the compression of the rubber block 8 reduces damage to the communication signal detector 4 during the pressing process.

[0029] The encapsulation top plate 5 includes a top plate 9 and a top plate 10. The top plate 9 is rotatably connected to the top of the limiting plate 2. The top plate 10 cooperates with the limiting component. An extension plate 11 is fixed on the top plate 9. An extension groove 12 is opened in the top plate 10. The extension groove 12 is slidably connected to the extension plate 11. A return spring 13 is fixed between the extension plate 11 and the groove wall of the extension groove 12.

[0030] With the above structure, the distance between top plate 9 and top plate 10 can be adjusted through the sliding fit between the extension plate 11 and the extension groove 12, so that the length of the encapsulation top plate 5 can be matched according to the distance between the limiting plate 2 and the limiting plate 3, thereby improving the stability of use.

[0031] The limiting assembly includes a pair of limiting blocks 14 fixed to the top of the limiting plate 2 3, a bidirectional screw 15 rotatably connected inside the limiting plate 2 3, a pair of limiting rings 16 fixed to one end of the top plate 2 10, the two limiting rings 16 engaging with the corresponding limiting blocks 14, and a pair of limiting inserts 17 slidably connected inside the limiting plate 2 3, each limiting insert 17 engaging with the corresponding limiting ring 16, and the threaded sections on both sides of the bidirectional screw 15 threadedly connected to the corresponding limiting inserts 17, a transmission worm gear 18 coaxially fixedly connected to the bidirectional screw 15, a transmission worm 19 rotatably connected inside the limiting plate 2 3, the transmission worm gear 18 meshing with the transmission worm 19, and an internal hexagonal nut 20 provided on the limiting plate 2 3, the internal hexagonal nut 20 coaxially fixedly connected to the transmission worm 19.

[0032] With the above structure, the transmission worm 19 can be rotated by the internal hex nut 20, the transmission worm 19 can be rotated by the transmission worm wheel 18, the transmission worm wheel 18 can be rotated by the shaft, and the bidirectional screw 15 can be rotated by the bidirectional screw 15, which in turn can push out the two limit blocks 17 to complete the insertion and engagement with the corresponding limit ring 16.

[0033] The control assembly includes a bidirectional lead screw 21 rotatably connected to the mounting base plate 1, a transmission bevel gear 22 rotatably connected to the mounting base plate 1, the transmission bevel gear 22 being coaxially fixedly connected to the bidirectional lead screw 21, and a transmission bevel gear 23 rotatably connected to the mounting base plate 1, the transmission bevel gear 22 meshing with the transmission bevel gear 23, and an internal hexagonal nut 24 being provided on the mounting base plate 1, the internal hexagonal nut 24 being coaxially fixedly connected to the transmission bevel gear 23, and a limiting plate 2 and a limiting plate 3 being threadedly connected to the corresponding threaded sections of the bidirectional lead screw 21.

[0034] With the above structure, the transmission bevel gear 23 can be rotated by the internal hex nut 24, which in turn drives the transmission bevel gear 22 to rotate. After the transmission bevel gear 22 rotates, it will drive the double-acting screw 21 to rotate. After the double-acting screw 21 rotates, it will drive the limiting plate 2 and the limiting plate 3 to move in opposite directions or in the opposite direction, thereby realizing the clamping action.

[0035] Each limit bolt 7 has a guide groove 25, and each guide groove 25 is slidably connected to a guide block 26. Each guide block 26 is fixed with a push spring 27 between it and the bottom of the corresponding guide groove 25. Each guide block 26 is fixedly connected to the corresponding extrusion block 8.

[0036] With the above structure, the guide block 26 can be pushed by the push spring 27, and the guide block 26 can further squeeze and press the rubber block 8, so that the rubber block 8 contacts and limits the concave and convex structure of the communication signal detector 4 housing, thereby improving the stability of the communication signal detector 4. Furthermore, the squeezing and limiting force can be adjusted by rotating the limiting bolt 7 and adjusting the degree of screwing in the limiting bolt 7.

[0037] The working principle of this utility model is as follows: First, the mounting base plate 1 is fixed to the detection position using bolts. Then, the communication signal detector 4 is placed on the mounting base plate 1. The hexagonal nut 24 drives the transmission bevel gear 23 to rotate, which in turn drives the transmission bevel gear 22 to rotate. The rotation of the transmission bevel gear 22 then drives the double-acting screw 21 to rotate. The rotation of the double-acting screw 21 then drives the limiting plates 2 and 3 to move relative to each other or in opposite directions, thus clamping the communication signal detector 4. Next, the encapsulation top plate 5 is rotated to a horizontal position. Then, the hexagonal nut 20 drives the transmission worm gear 19 to rotate, which in turn drives the transmission worm wheel 18 to rotate. After the 18-axis is rotated, the bidirectional screw 15 will be driven to rotate. The bidirectional screw 15 will then drive the two limiting blocks 17 to be pushed out, completing the insertion and engagement with the corresponding limiting ring 16. This forms a cover on the top of the communication signal detector 4, improving the limiting effect and protecting the top structure of the communication signal detector 4. Then, by threading limiting bolts 7 on the limiting plate 1 2, the limiting plate 2 3, and the encapsulation top plate 5, the communication signal detector 4 is limited and fixed in different positions by multiple limiting bolts 7. This allows the extrusion block 8 to contact and limit the concave and convex structure of the communication signal detector 4 housing, improving the stability of the communication signal detector 4. Furthermore, by rotating the limiting bolts 7, the extrusion limiting force can be adjusted by the degree of screwing in the limiting bolts 7.

[0038] In summary, by controlling the distance between limit plate 2 and limit plate 3 through the regulating component, adjustments are made according to the model and size of the communication signal detector 4. Furthermore, by controlling the limiting state of the top plate 5 through the limiting component, the communication signal detector 4 is fixed and limited, thereby enabling rapid disassembly and assembly of the communication signal detector 4 for easy replacement and maintenance. Additionally, multiple limiting screws press the communication signal detector 4 from different positions, further improving the fixing effect of the communication signal detector 4. Moreover, by squeezing the rubber block 8, damage to the communication signal detector 4 during the pressing process is reduced.
