Description

Technical Field

[0001] This invention relates to the field of satellite communication technology, specifically to a satellite communication terminal with dual satellite communication modules. Background Technology

[0002] In today's era of globalized communication, satellite communication terminals occupy an irreplaceable and important position in the field of communication due to their wide coverage, high communication throughput, and high communication efficiency. Currently available satellite communication products mainly include ground station communication terminals, vehicle-mounted, and shipborne satellite communication terminals. However, current satellite communication terminals are often quite large, requiring vehicles to transport various components before assembly and testing. This increases transportation costs and testing time, making them inconvenient for use in emergency rescue situations.

[0003] For example, Chinese patent CN214205532U, entitled "A Portable Satellite Communication Terminal," includes a gimbal, a support mechanism disposed at the bottom of the gimbal, and a signal transmission mechanism hinged to the gimbal. The support mechanism includes a positioning disk connected to the gimbal, and at least three evenly distributed support legs are hinged around the positioning disk. This utility model is convenient to use. By utilizing multiple hinged and retractable support legs, it can reduce the space occupied during transportation. At the same time, this structure is lighter and more convenient for users to carry and install outdoors.

[0004] While the portable satellite communication terminal mentioned in the aforementioned patent is practical and convenient, it also has its shortcomings. Nowadays, satellite communication terminals generally disassemble components such as antennas and brackets and put them into a storage box to reduce their size, making them easier to transport and carry, and improving transportation safety to avoid damage to the device during transportation. However, when installation is required, each component needs to be taken out of the storage box and then gradually assembled. This method increases the complexity of manual operation and takes a long time to set up, activate, and store. Summary of the Invention

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-9The present invention provides a technical solution: a satellite communication terminal with dual satellite communication modules includes a housing 2, a cover 1 hinged to the housing 2, a first transmission component, a second transmission component, multiple second antenna panels 32, and a linkage component. A support plate 10 is vertically slidably connected inside the housing 2. A first antenna panel 29 is rotatably connected to the support plate 10. The first antenna panel 29 has a first stroke and a second stroke during its rotation relative to the support plate 10. The first transmission component is driven by the opening action of the cover 1 to move the support plate 10 upward. The second transmission component is driven by the upward movement of the support plate 10 to rotate and unfold the first antenna panel 29 relative to the support plate 10. Each second antenna panel 32 is rotatably connected to the circumferential side of the first antenna panel 29 in a circumferential array. The linkage component is driven by the second stroke during the rotation of the first antenna panel 29 to rotate the entire second antenna panel 32 into a trumpet shape.

[0030] As a preferred technical solution, the first transmission assembly includes a rotating shaft 3, a first bevel gear 5, a second bevel gear 4 meshing with the first bevel gear 5, a first rotating rod 6, and a slider 8. The rotating shaft 3 is rotatably connected inside the housing 2, and the housing cover 1 is hinged to the housing 2 via the rotating shaft 3. The first bevel gear 5 is sleeved on the rotating shaft 3, and the second bevel gear 4 is horizontally rotatably connected inside the housing 2. The first rotating rod 6 is coaxially fixedly connected to the bottom end of the second bevel gear 4, and the slider 8 is vertically slidably sleeved on the first rotating rod 6. One side of the slider 8 is fixedly connected to the support plate 10. Specifically, when the housing cover 1 is opened, the housing cover 1 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the first bevel gear 5 to rotate. Through meshing transmission, the first bevel gear 5 drives the second bevel gear 4 to rotate, and the second bevel gear 4 drives the first rotating rod 6 to rotate. Driven by the rotation of the first rotating rod 6, the slider 8 drives the support plate 10 to move upward, thereby moving the first antenna panel 29 upward out of the housing 2 for better signal reception.

[0031] As a preferred technical solution, a first spiral groove 7 is provided on the first rotating rod 6, and a first protrusion is provided inside the slider 8. The first protrusion and the first spiral groove 7 are slidably engaged. A guide groove 9 is vertically provided inside the housing 2, and the slider 8 is slidably connected in the guide groove 9. Specifically, through the sliding engagement between the first protrusion and the first spiral groove 7, and at the same time, the guide groove 9 restricts the circumferential rotation of the slider 8, so that the slider 8 can only move in a straight line, causing the spiral drive belt 18 of the rotating rod to move the support plate 10 upward. Preferably, the peripheral side of the support plate 10 is in contact with the inner wall of the housing 2, further restricting the circumferential rotation of the slider 8, making the movement stroke more stable.

[0032] As a preferred technical solution, the second transmission assembly includes a first gear 13, a first rack 14 meshing with the first gear 13, a hinge seat 11, a hinge shaft 12, a connecting plate 22, and a wheel 23. The hinge seat 11 is disposed on the top of the support plate 10, the hinge shaft 12 is rotatably connected to the hinge seat 11, the connecting plate 22 is sleeved on the hinge shaft 12, the circumferential side of the wheel 23 is fixedly connected to the connecting plate 22, and a plurality of connecting rods 28 are provided between the bottom of the wheel 23 and the first antenna panel 29. The first gear 13 is coaxially fixedly connected to the hinge shaft 13. At one end of 2, the first rack 14 is vertically installed inside the housing 2. Specifically, during the upward movement of the support plate 10, the meshing transmission between the first gear 13 and the first rack 14 causes the hinge shaft 12 to drive the connecting plate 22 to rotate toward the housing cover 1. The connecting plate 22 drives the wheel 23 to rotate, and the wheel 23 drives the first antenna panel 29 to rotate and unfold through each connecting rod 28, thereby adjusting the signal angle of the first antenna panel 29, enabling the first antenna panel 29 to better receive signal transmission and reducing the splicing and installation time of each component.

[0033] As a preferred technical solution, the linkage assembly includes a gear ring 21, multiple sleeves 26, multiple connecting blocks 30, and multiple cylindrical pins 25. The gear ring 21 is rotatably connected inside the wheel 23. Each sleeve 26 is arranged in a circumferential array on the wheel 23. One end of each connecting block 30 is rotatably connected to a sleeve 26, and the other end of each connecting block 30 is fixedly connected to each second antenna panel 32. Each cylindrical pin 25 is arranged in a circumferential array and fixedly connected to the top of the gear ring 21. Each connecting block 30 has a third helical groove 31, and each cylindrical pin 25 slides in a corresponding manner with each third helical groove 31. Specifically, the gear ring 21 rotates relative to the wheel 23, simultaneously driving the top of the connecting block 21 to rotate. Multiple cylindrical pins 25 rotate, and each cylindrical pin 25 slides with its corresponding third spiral groove 31. Through compression, the connecting block 30 rotates relative to the sleeve 26. The circumferential side of the sleeve 26 fits against the inner wall of the connecting block 30 to achieve a limiting effect, preventing displacement of the sleeve 26 along its axis during the rotation of the connecting block 30. The distance and angle between each second antenna panel 32 are different, affecting the reception of satellite signals. Each connecting block 30 drives the corresponding second antenna panel 32 to rotate and unfold. Each second antenna panel 32 and the first antenna panel 29 together form a dish shape, which is conducive to the convergence of electromagnetic waves, making the signal more concentrated and clear, and enabling better reception of satellite signals.

[0034] As a preferred technical solution, a second gear 20 that meshes with a gear ring 21 is rotatably connected inside the connecting plate 22. A second rotating rod 15 is rotatably connected inside the connecting plate 22. A second rack 17 that meshes with the second gear 20 is horizontally slidably connected to the second rotating rod 15. A transmission belt 18 is rotatably sleeved on both the hinge shaft 12 and the second rotating rod 15. Specifically, the second rotating rod 15 revolves synchronously with the connecting plate 22. When the hinge shaft 12 rotates, the transmission belt 18 causes the second rotating rod 15 to rotate relative to the connecting plate 22. The rotational drive causes the second rack 17 to move toward the second gear 20, and the second rack 17 does not mesh with the second gear 20 during the first stroke, so as to avoid the second antenna panel 32 unfolding and rigidly colliding with the support plate 10 during the initial rotation of the first antenna panel 29, causing motion interference. When the first antenna panel 29 rotates to a certain angle, the second rack 17 meshes with the second gear 20 during the second stroke, driving the gear ring 21 to rotate, realizing the rotation and unfolding of each second antenna panel 32, simplifying the steps of setting up and activating each component.

[0035] As a preferred technical solution, the second rotating rod 15 is provided with a second spiral groove 19, and the second rack 17 is provided with a second protrusion. The second protrusion is slidably engaged with the second spiral groove 19. The connecting plate 22 is provided with a first sliding groove 35 horizontally. The second rack 17 is slidably connected in the first sliding groove 35. A guide rod 16 is provided horizontally in the first sliding groove 35. The second rack 17 is slidably sleeved on the guide rod 16. Specifically, through the sliding engagement between the second protrusion and the second spiral groove 19, and at the same time, the guide rod 16 restricts the circumferential rotation of the second rack 17, so that the slider 8 can only move in a straight line, causing the spiral drive belt 18 of the rotating rod to move the support plate 10 upward. Preferably, the peripheral side of the support plate 10 is in contact with the inner wall of the housing 2, further restricting the circumferential rotation of the slider 8, making the movement stroke more stable.

[0036] As a preferred technical solution, an annular groove 24 is provided on the wheel 23, and each cylindrical pin 25 is slidably connected to the annular groove 24. Specifically, the annular groove 24 serves to guide the movement path of each cylindrical pin 25.

[0037] As a preferred technical solution, each sleeve 26 has an arc-shaped groove 27, each arc-shaped groove 27 is connected to the annular groove 24, and each arc-shaped groove 27 is connected to each third spiral groove 31 in a one-to-one correspondence. Specifically, when the cylindrical pin 25 moves along the annular groove 24, when it enters the arc-shaped groove 27, the top of the cylindrical pin 25 slides into the corresponding third spiral groove 31, and the second antenna panel 32 is simultaneously unfolded through each connecting block 30.

[0038] As a preferred technical solution, each of the second antenna panels 32 is hinged with a telescopic rod 34 on the side closest to each other, and a feed 33 is provided at the end of each telescopic rod 34 closest to each other. Specifically, during the rotation and unfolding of each second antenna panel 32, the telescopic rod 34 is used to adapt to the changes in distance and angle between each second antenna panel 32 and the feed 33, so that the feed 33 is always aligned with the center of the first antenna panel 29, realizing one-click satellite alignment, and ensuring that the signal can be effectively focused and received.

[0039] Working principle: When the satellite communication terminal with dual satellite communication modules is in operation, opening the cover 1 causes the rotating shaft 3 to rotate, which in turn drives the first bevel gear 5 to rotate. Through meshing transmission, the first bevel gear 5 drives the second bevel gear 4 to rotate, which in turn drives the first rotating rod 6 to rotate. The rotation of the first rotating rod 6 drives the slider 8 to move the support plate 10 upward, lifting the first antenna panel 29 and the second antenna panel 32 out of the housing 2 for better satellite signal reception. During the upward movement of the support plate 10, the meshing transmission between the first gear 13 and the first rack 14 causes the hinge shaft 12 to drive the connecting plate 22 to rotate toward the cover 1. The connecting plate 22 drives the wheel 23 to rotate, and the wheel 23... Each connecting rod 28 drives the first antenna panel 29 to rotate and unfold, thereby adjusting the signal angle of the first antenna panel 29 and enabling it to better receive signal transmission. This reduces the assembly time of each component. The second rotating rod 15 revolves synchronously with the connecting plate 22, and the hinge shaft 12 rotates. Through the transmission belt 18, the second rotating rod 15 rotates relative to the connecting plate 22. The rotation of the second rotating rod 15 drives the second rack 17 to move toward the second gear 20. The second rack 17 does not mesh with the second gear 20 during the first stroke to avoid the second antenna panel 32 unfolding and rigidly colliding with the support plate 10 during the initial rotation of the first antenna panel 29, thus preventing motion interference. When the first antenna panel 29 rotates to a certain angle, the second rack 17 meshes with the second gear 20 during the second stroke, driving the gear ring 21 to rotate. The gear ring 21 rotates relative to the circular wheel 23, simultaneously driving the multiple cylindrical pins 25 set at the top to rotate. Each cylindrical pin 25 slides with its corresponding third spiral groove 31, and through compression, drives the connecting block 30 to rotate relative to the sleeve 26. The peripheral side of the sleeve 26 fits against the inner wall of the connecting block 30 to achieve a limiting effect, preventing displacement of the sleeve 26 along its axis during the rotation of the connecting block 30. The different distances and angles between the second antenna panels 32 affect the reception of satellite signals. Each connecting block 30 drives the corresponding second antenna panel 32 to rotate and unfold. Each second antenna panel 32 and the first The antenna panels 29 together form a dish shape, which is conducive to the convergence of electromagnetic waves, making the signal more concentrated and clear, and enabling better reception of satellite signals. During the rotation and unfolding of each second antenna panel 32, the telescopic rod 34 adapts to the changes in distance and angle between each second antenna panel 32 and the feed 33, so that the feed 33 is always aligned with the center of the first antenna panel 29, realizing one-click satellite alignment, and ensuring that the signal can be effectively focused and received. The overall device greatly reduces the size of the satellite communication terminal. Only the cover 1 needs to be unfolded. There is no need to reassemble or disassemble the first antenna panel 29 and each second antenna panel 32, making the operation simpler and reducing the time for setup, activation and storage, realizing one-click storage and unfolding.

[0040] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
