Description

Technical Field

[0002] In the era of globalized communications, satellite communication terminals have an irreplaceable and important position in the communications field due to their wide coverage, large communication throughput and high communication efficiency. The existing satellite communication products mainly include ground station communication terminals, vehicle-mounted and ship-mounted satellite communication terminals, but the current satellite communication terminals are often large in size and require vehicles to transport various components, and then assemble and test them.

A support plate 10 is vertically slidably connected in the box body 2, and 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 the rotation relative to the support plate 10. The first transmission assembly is driven by the opening action of the box cover 1 to move the support plate 10 upward, and the second transmission assembly 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 peripheral side of the first antenna panel 29 in a circular array. The linkage assembly is driven by the second stroke during the rotation of the first antenna panel 29 to rotate each second antenna panel 32 in a trumpet shape as a whole.

[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 in the box body 2, and the box cover 1 is hinged to the box body 2 through the rotating shaft 3.

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 box cover 1 is opened, the box 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. The first rotating rod 6 is driven to rotate so that the slider 8 drives the support plate 10 to move upward, so that the first antenna panel 29 is moved upward out of the box body 2 to better receive signals.

[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 in the slider 8. The first protrusion is slidably matched with the first spiral groove 7. A guide groove 9 is vertically provided in the box body 2, and the slider 8 is slidably connected in the guide groove 9.

Specifically, during the upward movement of the support plate 10, the first gear 13 and the first rack 14 are meshed and transmitted, so that the hinge shaft 12 drives the connecting plate 22 to rotate toward the box cover 1, and the connecting plate 22 drives the round wheel 23 to rotate. The round wheel 23 drives the first antenna panel 29 to rotate and unfold through the connecting rods 28, so as to adjust the signal angle of the first antenna panel 29, so that the first antenna panel 29 can better receive the transmission of the signal, thereby reducing the time for splicing and installing 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.

One end of each connecting block 30 is rotatably sleeved with the sleeve 26 in a one-to-one correspondence, and the other end of each connecting block 30 is fixedly connected to each second antenna panel 32. Each cylindrical pin 25 is fixedly connected to the top of the gear ring 21 in a circular array. A third spiral groove 31 is opened in each connecting block 30, and each cylindrical pin 25 is slidably matched with each third spiral groove 31 in a one-to-one correspondence. Specifically, the gear ring 21 rotates relative to the circular wheel 23, and at the same time drives the top setting The multiple cylindrical pins 25 rotate, and each cylindrical pin 25 slides with the corresponding third spiral groove 31, and drives the connecting block 30 to rotate relative to the sleeve 26 through extrusion, and the peripheral side surface of the sleeve 26 fits with the inner wall of the connecting block 30 to achieve a limiting effect, thereby avoiding displacement of the sleeve 26 in the axial direction during the rotation of the connecting block 30. The distances and angles between the second antenna panels 32 are different, which affects 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 pot shape, which is conducive to the convergence of electromagnetic waves, making the signal more concentrated and clear, and able to better receive satellite signals.

[0034] As a preferred technical solution, a second gear 20 meshing with the gear ring 21 is rotatably connected in the connecting plate 22, a second rotating rod 15 is rotatably connected in the connecting plate 22, a second rack 17 meshing with the second gear 20 is horizontally slidably connected to the second rotating rod 15, and a transmission belt 18 is rotatably sleeved on the hinge shaft 12 and the second rotating rod 15. Specifically, the second rotating rod 15 and the connecting plate 22 revolve synchronously, the hinge shaft 12 rotates, and the transmission belt 18 drives the second rotating rod 15 to rotate relative to the connecting plate 22 through the transmission belt 18, and the second rotating rod 15 rotates relative to the connecting plate 22 through the transmission belt 18. The second rack 17 is driven to rotate so as to move toward the second gear 20, and the second rack 17 is not meshed with the second gear 20 in the first stroke, so as to avoid the second antenna panel 32 being deployed and rigidly colliding with the support plate 10 when the first antenna panel 29 just starts to rotate, thereby preventing motion interference. When the first antenna panel 29 rotates to a certain angle, the second rack 17 is meshed with the second gear 20 in the second stroke, driving the gear ring 21 to rotate, thereby realizing the rotation and deployment of each second antenna panel 32, and simplifying the steps of erecting and opening each component.

[0035] As a preferred technical solution, a second spiral groove 19 is provided on the second rotating rod 15, a second protrusion is provided in the second rack 17, the second protrusion is slidably matched with the second spiral groove 19, a first slide groove 35 is horizontally provided in the connecting plate 22, the second rack 17 is slidably connected in the first slide groove 35, a guide rod 16 is horizontally provided in the first slide groove 35, and the second rack 17 is slidably sleeved on the guide rod 16. Specifically, through the sliding cooperation between the second protrusion and the second spiral groove 19, the guide rod 16 limits the circumferential rotation of the second rack 17, so that the slider 8 can only move in a straight line, so that the spiral transmission belt 18 of the rotating rod drives the support plate 10 to move upward, and preferably the circumferential side surface of the support plate 10 is in contact with the inner wall of the box body 2, which further limits the circumferential rotation of the slider 8 and makes the movement stroke more stable.

Specifically, when the cylindrical pin 25 moves along the annular groove 24, when it enters the arc groove 27, the top of the cylindrical pin 25 slides with the corresponding third spiral groove 31, and drives each second antenna panel 32 to unfold simultaneously through each connecting block 30.

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

In the process of the support plate 10 moving upward, the meshing transmission of the first gear 13 and the first rack 14 is used to make the hinge shaft 12 drive the connecting plate 22 to rotate toward the box cover 1, and the connecting plate 22 drives the round wheel 23 to rotate, and the round wheel 23 is driven by the first gear 13 and the first rack 14. Each connecting rod 28 drives the first antenna panel 29 to rotate and unfold, so as to adjust the signal angle of the first antenna panel 29, so that the first antenna panel 29 can better receive the signal transmission, and the time of splicing and installing each component is reduced. The second rotating rod 15 revolves synchronously with the connecting plate 22, and the hinge shaft 12 rotates.

The second rotating rod 15 is driven to rotate so as to move the second rack 17 toward the second gear 20, and the second rack 17 does not mesh with the second gear 20 in the first stroke, so as to avoid that the second antenna panel 32 is unfolded and collides with the support plate 10 rigidly when the first antenna panel 29 just starts to rotate, causing motion interference. When the first antenna panel 29 rotates to a certain angle, the second rack 17 meshes with the second gear 20 in the second stroke, driving the ring gear 21 to rotate, and the ring gear 21 rotates relative to the circular wheel 23, while driving a plurality of cylindrical pins 25 arranged on the top to rotate, and each cylindrical pin 25 slides with the corresponding third spiral groove 31, and drives the connecting block 30 to rotate relative to the sleeve 26 through extrusion, and the peripheral side surface of the sleeve 26 fits with the inner wall of the connecting block 30 to achieve a limiting effect, avoiding displacement of the sleeve 26 in the axial direction during the rotation of the connecting block 30, and the distances and angles between the second antenna panels 32 are different, which affects the reception of satellite signals, and each connecting block 30 drives the corresponding second antenna panel 32 to rotate and unfold, and each second antenna panel 32 and the first The antenna panels 29 together form a pot shape, which is conducive to the convergence of electromagnetic waves, making the signal more concentrated and clear, and better able to receive satellite signals. During the rotation and expansion of each second antenna panel 32, the telescopic rod 34 is used to adapt to the distance and angle changes between each second antenna panel 32 and the feed source 33, so that the feed source 33 is always aligned with the center of the first antenna panel 29, realizing one-click star alignment to ensure that the signal can be effectively focused and received. The overall device greatly reduces the volume of the satellite communication terminal. It only needs to unfold the box cover 1.
