[0018] To better understand the purpose, structure and function of the present invention, the test device for satellite communication antenna of the present invention and its usage method will be further described in detail below with reference to the drawings.

[0019] Figure 1 , 2 Schematically shows the overall structure of the test device for satellite communication antenna according to the present invention. In the embodiment as Figure 1 shown, the test device for satellite communication antenna includes a connecting platform 1, and a mounting plate 2 provided on the connecting platform 1 for placing a satellite communication antenna (not shown in the figure). At the same time, a pitch adjustment mechanism 3 is further provided on the connecting platform 1, and the pitch adjustment mechanism 3 is arranged to be coupled with the mounting plate 2 to drive the mounting plate 2 to perform pitch motion.

[0020] In this way, the pitch adjustment mechanism 3 can apply a force to the mounting plate 2, so that the mounting plate 2 performs pitch motion, and then drives the satellite communication antenna located on the mounting plate 2 to generate pitch motion. Thus, the orientation of the free end of the satellite communication antenna can be adjusted. In this setting mode, the orientation of the satellite communication antenna can be adjusted correspondingly according to the direction of the satellite signal. Thus, the practicability of the present device can be improved, and it is ensured that the satellite communication antenna can reach the best working state before actual deployment.

[0021] At the same time, as Figure 1 , 2As shown, the test device for a satellite communication antenna further includes a rotating mechanism 4 coupled to the connection platform 1 for driving the mounting disk 2 to rotate, and a lifting adjustment mechanism 5 coupled to the connection platform 1 for driving the mounting disk 2 to move up and down. In this embodiment, the pitch adjustment mechanism 3, the rotating mechanism 4, and the lifting adjustment mechanism 5 are arranged to allow them to act together on the mounting disk 2 to adjust the orientation angle of the satellite communication antenna located on the mounting disk 2. In this way, the satellite antenna located on the mounting disk 2 can be adjusted in multiple dimensions to simulate a dynamic environment, so that the test of the satellite antenna is more in line with the actual work.

[0022] In this setting method, when it is necessary to test the satellite communication antenna, first, the satellite communication antenna (not shown in the figure) is set on the mounting disk 2. At the same time, the lifting adjustment mechanism 5 is started. At this time, the lifting adjustment mechanism 5 will continuously output a force towards the connection platform 1, so that the connection platform 1 continuously moves up or down, and then the satellite communication antenna continuously moves up or down. Until the satellite communication antenna is in a position convenient for receiving satellite signals in the vertical direction.

[0023] Then, the pitch adjustment mechanism 3 is started. At this time, the pitch adjustment mechanism 3 will continuously apply a force to the mounting disk 2, so that the mounting disk 2 performs a pitch movement, and then drives the satellite communication antenna located on the mounting disk 2 to perform a pitch movement. Until the satellite communication antenna is in a position convenient for receiving satellite signals.

[0024] Finally, the rotating mechanism 4 is started. During this process, the rotating mechanism 4 will continuously output a force towards the connection platform 1, so that the connection platform 1 continuously rotates, and then the satellite communication antenna continuously moves in the circumferential direction. Until the satellite communication antenna is in a position convenient for receiving satellite signals in the circumferential direction.

[0025] In this way, the satellite antenna located on the mounting disk 2 can be adjusted in multiple dimensions to simulate a dynamic environment, so that the test of the satellite antenna is more in line with the actual work.

[0026] In one embodiment, as Figure 3 shown, the connection platform 1 includes a bottom 11 and a side portion 12 provided on the bottom 11 and extending upward. The bottom 11 and the side portion 12 together form a cavity 13 for accommodating the mounting disk 2. In this embodiment, the mounting disk 2 is horizontally arranged in the cavity 13. In this way, when the satellite communication antenna is set on the mounting disk 2, the satellite communication antenna can form a vertical relationship with the mounting disk 2.

[0027] Meanwhile, in the illustrated embodiment, the pitch adjustment mechanism 3 is horizontally disposed on the side portion 12, and the force output end of the pitch adjustment mechanism 3 extends into the cavity 13 and is interconnected with the mounting plate 2 to output a force toward the mounting plate 2 to drive the mounting plate 2 to perform a pitch motion.

[0028] In this embodiment, as Figure 3 shown, the pitch adjustment mechanism 3 is configured as a servo motor, and the force output end of the servo motor is relatively fixed to the mounting plate 2. At the same time, the axis of the force output end of the pitch adjustment mechanism 3 is perpendicular to the axis direction of the mounting plate 2.

[0029] In this way, when the force output end of the pitch adjustment mechanism 3 rotates, it can drive the axis of the mounting plate 2 to move along a direction perpendicular to the axis of the force output end of the pitch adjustment mechanism 3. Thus, the satellite communication antenna located on the mounting plate 2 can perform a pitch motion.

[0030] In this setting mode, when it is necessary to make the mounting plate 2 perform a pitch motion, the servo motor is started. During this process, the force of the servo motor is transmitted to the mounting plate 2, thereby driving the mounting plate 2 to perform a pitch motion, and further adjusting the orientation of the satellite communication antenna.

[0031] In this embodiment, when it is necessary to rotate the mounting plate 2 to a specific position, a pulse signal corresponding to the target position is sent to the servo motor, so that the servo motor can drive the mounting plate 2 to a specific position. It should be noted that the servo motor and the driving method of the servo motor are well known to those skilled in the art.

[0032] In one embodiment, as Figure 4 、 5 shown, the rotation mechanism 4 includes a turntable 41 that is relatively fixed to the connection platform 1. In this embodiment, the turntable 41 is relatively fixed to the bottom 11. At the same time, the rotation mechanism 4 further includes a rotating box 42 disposed below the turntable 41, and a rotating assembly 43 is disposed in the rotating box 42, and the rotating assembly 43 is configured to allow the turntable 41 to rotate.

[0033] In this way, when the rotating assembly 43 drives the rotation of the turntable 41, the turntable 41 will drive the bottom 11 to move together, thereby causing the connection platform 1 to move. During this process, the connection platform 1 will drive the mounting plate 2 located in the cavity 13 to move synchronously. Thus, the satellite communication antenna located on the mounting plate 2 can perform a rotational motion.

[0034] According to a preferred embodiment of the present invention, as Figure 5As shown, the rotating assembly 43 includes a motor 431 disposed within the rotating box 42, and a speed reducer 432 disposed at the force output end of the motor 431. The force output end of the speed reducer 432 is configured to be fixedly connected to the turntable 41.

[0035] In this way, when it is necessary to generate a rotational movement of the turntable 41, the motor 431 can be started, so that the motor 431 drives the speed reducer 432 to move. Thus, the speed reducer 432 can drive the turntable 41 to move. However, when it is necessary to adjust the rotational speed of the turntable 41, the rotational speed of the force output end of the speed reducer 432 can also be adjusted, thereby adjusting the rotational speed of the turntable 41. Thus, the turntable 41 can perform a rotational movement at a specific rotational speed. It should be noted that the motor 431, the speed reducer 432, the connection relationship between the motor 431 and the speed reducer 432, the connection relationship between the speed reducer 432 and the turntable 41, and the method of adjusting the rotational speed of the force output end of the speed reducer 432 are all well-known to those skilled in the art.

[0036] In this embodiment, as Figure 6 shown, the lifting adjustment mechanism 5 includes a lifting box 51 disposed below the rotating box 42. A telescopic assembly 52 is disposed within the lifting box 51. The force output end of the telescopic assembly 52 is fixedly connected to the bottom of the rotating box 42. In this way, when it is necessary for the connecting platform 1 to perform a lifting movement, the telescopic assembly 52 can be started.

[0037] During this process, as Figure 6 shown, the force output end of the telescopic assembly 52 will continuously output a force towards the rotating box 42, thereby driving the rotating box 42 to perform a lifting movement. As the rotating box 42 performs a lifting movement, the rotating box 42 will continuously transmit the force to the connecting platform 1, and further enable the connecting platform 1 to generate a lifting movement. At this time, the connecting platform 1 will drive the mounting disk 2 located within the cavity 13 to move synchronously. Thus, the satellite communication antenna located on the mounting disk 2 can be lifted.

[0038] According to a preferred embodiment of the present invention, as Figure 6 shown, the telescopic assembly 52 is configured as an electric telescopic rod, and the end of the electric telescopic rod is fixed within the lifting box 51, and the free end extends to the bottom of the rotating box 42 and is fixedly connected to the bottom of the rotating box 42.

[0039] In this way, when the electric telescopic rod is started, the acting force of the electric telescopic rod can be continuously output to the bottom of the rotating box 42, thereby driving the rotating box 42 to perform a lifting motion. As the rotating box 42 performs a lifting motion, the rotating box 42 will continuously transmit the acting force to the connecting platform 1, and further enable the connecting platform 1 to generate a lifting motion. At this time, the connecting platform 1 will drive the mounting plate 2 located in the cavity 13 to move synchronously. Thus, the satellite communication antenna located on the mounting plate 2 can be made to generate a lifting motion. It should be noted that the electric telescopic rod, the connection relationship between the electric telescopic rod and the rotating box 42, the starting method of the electric telescopic rod, and the specific structure of the electric telescopic rod are all well-known to those skilled in the art.

[0040] In one embodiment, as Figure 1 , 2 shown, the test device for the satellite communication antenna further includes a support mechanism 6. In this embodiment, the support mechanism 6 is provided with at least two, and the support mechanism 6 is arranged on both sides of the connecting platform 1 in a corresponding manner. In this way, the support mechanism 6 can apply acting forces towards the connecting platform 1 respectively. Thus, the connecting platform 1 can be supported, so that the connecting platform 1 is stably arranged.

[0041] In this embodiment, as Figure 7 , 8 shown, the support mechanism 6 includes a first support base 61, and a first support rod 62 rotatably arranged on the first support base 61. At the same time, a first support portion 63 is further provided at the free end of the first support rod 62. In the illustrated embodiment, the first support portion 63 is configured to allow it to be fitted and arranged on the bottom 11 and be able to apply an acting force towards the bottom 11. In this way, the acting force from the support mechanism 6 can be transmitted to the bottom 11, thereby supporting the bottom 11, and further supporting the connecting platform 1. Thus, the connecting platform 1 is stably arranged.

[0042] According to a preferred embodiment of the present invention, as Figure 8 shown, the first support base 61 is arranged on the horizontal plane (foundation and the like) in a relatively fixed manner. At the same time, the first support rod 62 includes a fixed rod 621 rotatably arranged on the first support base 61, and a movable rod 622 inserted inside the fixed rod 621 and configured to allow movement along the axial direction of the fixed rod 621.

[0043] In this way, when it is necessary to adjust the magnitude of the force exerted by the support mechanism 6 on the bottom 11, the length of the movable rod 622 located within the fixed rod 621 can be adjusted, thereby adjusting the axial length of the first support rod 62, and further adjusting the magnitude of the force exerted by the first support rod 62 on the bottom 11.

[0044] However, when it is necessary to adjust the angle of the force exerted by the support mechanism 6 on the bottom 11, the fixed rod 621 is rotated along the first support base 61, thereby adjusting the angle formed between the fixed rod 621 and the first support base 61. Thus, the angle formed between the first support rod 62 and the first support base 61 is adjusted, thereby adjusting the angle of the force exerted by the support mechanism 6 on the bottom 11.

[0045] In addition, the first support portion 63 is provided at the free end of the movable rod 622 and is connected to the movable rod 622 in a rotatable manner. In this way, the first support portion 63 can rotate along the free end of the movable rod 622. Thus, the direction of the force exerted by the movable rod 622 on the bottom 11 can be changed. In this setting mode, the support mechanism 6 can further stably support the connection platform 1.

[0046] According to a preferred embodiment of the present invention, as Figure 1 、 2 shown, four support mechanisms 6 are provided and are distributed on the side surface of the connection platform 1 in a pairwise opposite manner. In this way, the four support mechanisms 6 can all output forces towards the connection platform 1. Thus, the connection platform 1 can be further supported, so that the connection platform 1 is stably arranged.

[0047] In one embodiment, as Figure 3 、 7 shown, the bottom 11 is provided in a circular structure, and a chute 111 recessed inward is provided along the circumference on the bottom 11. At the same time, a slider 631 is further provided on the radially inner side of the first support portion 63, and the curvature of the radially inner side of the slider 631 is configured to be equivalent to the curvature of the chute 111. In this way, the slider 631 can be abutted within the chute 111.

[0048] In this setting mode, as Figure 1As shown, the sliding groove 111 can also limit the slider 631, thereby preventing the slider 631 from moving vertically. Thus, the support mechanism 6 can further stably support the connecting platform 1. However, it should be noted that the force exerted by the support mechanism 6 on the connecting platform 1 is not greater than the force exerted by the rotating assembly 43 on the bottom 11. Specifically, when the connecting platform 1 receives the force from the support mechanism 6, the connecting platform 1 can still be rotated by the rotating assembly 43.

[0049] According to a preferred embodiment of the present invention, as Figure 7 shown, a number of spherical balls 632 are also provided on the upper and lower sides of the slider 631, and each of the spherical balls 632 is configured to be rotatable on the slider 631. At the same time, the spherical balls 632 located on the upper and lower sides of the slider 631 can be in contact with the upper and lower sides of the sliding groove 111. In this way, when the bottom 11 rotates, the friction between the bottom and the slider 631 can be reduced through the spherical balls 632, so that the bottom 11 can rotate smoothly.

[0050] In one embodiment, as Figure 1 、 2 、3 shown, the test device for a satellite communication antenna further includes a receiving seat 7. In this embodiment, the receiving seat 7 is disposed below the lifting adjustment mechanism 5 and is configured to be fixedly coupled to the lifting adjustment mechanism 5. In this way, the receiving seat 7 can carry the lifting adjustment mechanism 5 and the rotating mechanism 4 and the pitching adjustment mechanism 3 located above the lifting adjustment mechanism 5. In this way, the lifting adjustment mechanism 5, the rotating mechanism 4, and the pitching adjustment mechanism 3 can be separated from the horizontal plane (foundation and the like). Thus, it is possible to prevent the horizontal plane from contaminating the lifting adjustment mechanism 5, the rotating mechanism 4, and the pitching adjustment mechanism 3.

[0051] In the illustrated embodiment, as Figure 3 shown, a support pair 71 is further provided on the receiving seat 7, and the free end of the support pair 71 is configured to be coupled to the first support rod 62. In this way, the support pair 71 can support the first support rod 62, so that the first support rod 62 stably exerts a force on the bottom 11.

[0052] In this embodiment, as Figure 9As shown, the supporting pair 71 includes a second supporting seat 711 relatively fixed on the receiving seat 7, a second supporting rod 712 rotatably connected to the second supporting seat 711, and a supporting ring 713 provided on the second supporting rod 712. The supporting ring 713 is sleeved on the first supporting rod 62 and allows the first supporting rod 62 to move along the axial direction of the supporting ring 713. Among them, the structure of the second supporting rod 712 is set to be the same as that of the first supporting rod 62. Therefore, it will not be elaborated here.

[0053] In this setting mode, the supporting angle of the supporting pair 71 towards the first supporting rod 62 and the magnitude of the supporting force can be adjusted by adjusting the angle between the second supporting rod 712 and the second supporting seat 711 and the length of the second supporting rod 712. Therefore, the first supporting rod 62 can stably apply a force towards the bottom 11.

[0054] According to a preferred embodiment of the present invention, as Figure 9 shown, the supporting ring 713 is rotatably arranged on the second supporting rod 712. In this way, the angle between the supporting ring 713 and the second supporting rod 712 can be adjusted. Therefore, the supporting angle of the supporting pair 71 towards the first supporting rod 62 can be further adjusted.

[0055] In one embodiment, as Figure 3 shown, a slot 72 extending outwards is further provided on the side surface of the receiving seat 7. At the same time, the supporting mechanism 6 further includes a supporting platform 64, and the supporting platform 64 includes an insertion block 641, a pressure dividing plate 642 and a positioning seat 643 connected together in sequence. Among them, the insertion block 641 is configured to be allowed to be inserted into the slot 72 and move along the path formed by the slot 72.

[0056] In addition, as Figure 7 、 8 shown, the first supporting seat 61 is relatively fixedly arranged on the pressure dividing plate 642. In this setting mode, the relative distance between the supporting mechanism 6 and the bottom 11 can be adjusted by adjusting the length of the insertion block 641 located in the slot 72. It should be noted that in this embodiment, four slots 72 are provided and are distributed on the side surface of the receiving seat 7 in a pairwise opposite manner. In this way, the supporting mechanism 6 can be connected to the receiving seat 7 in four directions. In this setting mode, the four supporting mechanisms 6 can jointly fix the receiving seat 7. Therefore, the receiving seat 7 can stably support the lifting adjustment mechanism 5.

[0057] In one embodiment, as Figure 7 、 8As shown, the surface area of the pressure dividing plate 642 is configured to be larger than the surface area of the first support base 61. In this way, the force borne by the first support base 61 can be transferred to the pressure dividing plate 642, and pressure division is carried out through the pressure dividing plate 642. Thereby, the effect of protecting the first support base 61 can be achieved.

[0058] According to a preferred embodiment of the present invention, as Figure 7 、 8 shown, a fastening bolt 65 is further provided on the positioning base 643, and the fastening bolt 65 is configured to allow connection with a horizontal plane (foundation and the like). In this setting manner, the device can be fixed on the horizontal plane through the fastening bolt 65 and the positioning base 643, so that the device is stably arranged on the horizontal plane.

[0059] In one embodiment, as Figure 3 shown, a fixing member 73 is further provided on the receiving base 7. In this embodiment, the fixing member 73 is arranged in an "L" shape, and two adjacent sides of the fixing member 73 are respectively arranged on the receiving base 7 and the lifting adjustment mechanism 5. At the same time, a plurality of screws 731 are further provided on the fixing member 73, and the screws 731 are configured to allow the receiving base 7, the lifting adjustment mechanism 5 and the fixing member 731 to be connected to each other respectively. In this way, the receiving base 7 and the lifting adjustment mechanism 5 are relatively fixed together.

[0060] According to a preferred embodiment of the present invention, as Figure 9 shown, a reinforcing rib 732 is further provided on the fixing member 73, and the reinforcing rib 732 is used to connect two adjacent sides of the fixing member 73. In this way, the strength of the fixing member 73 can be increased, so that the fixing member 73 can stably connect the receiving base 7 and the lifting adjustment mechanism 5 together.

[0061] The operation of the test device for a satellite communication antenna according to the present invention is as follows.

[0062] First, connect the connecting platform 1, the rotating mechanism 4, and the lifting adjustment mechanism 5 in sequence, and make the turntable 41 relatively fixed to the bottom 11, and the force output end of the rotating assembly 43 is connected to the turntable 41 to drive the turntable 41 to move.

[0063] At the same time, the force output end of the telescopic assembly 52 is relatively fixed to the bottom of the rotating box 42. In addition, a receiving base 7 is provided at the bottom of the lifting adjustment mechanism 5, a support mechanism 6 is provided outside the receiving base 7, and the support mechanism 6 is connected to the receiving base 7.

[0064] Secondly, place the mounting disk 2 within the cavity 13 formed by the connecting platform 1, and set a satellite communication antenna on the mounting disk 2. Meanwhile, set a pitch adjustment mechanism 3 on the side of the connecting platform 1, and extend the force output end of the pitch adjustment mechanism 3 into the cavity 13 to be interconnected with the mounting disk 2, so as to output a force towards the mounting disk 2 to drive the mounting disk 2 to perform a pitch motion. Thus, the assembly of this device is completed.

[0065] In this setting mode, when it is necessary to make the mounting disk 2 perform a pitch motion, start the pitch adjustment mechanism 3. In this embodiment, since the pitch adjustment mechanism 3 is set as a servo motor, the force of the servo motor will be transmitted to the mounting disk 2, thereby driving the mounting disk 2 to perform a pitch motion, and further adjusting the orientation of the satellite communication antenna.

[0066] When it is necessary to make the turntable 41 generate a rotational motion, start the rotating assembly 43. In this embodiment, since the rotating assembly 43 is set as a motor 431 and a reducer 432, the motor 431 can drive the reducer 432 to move. Thus, the reducer 432 can drive the turntable 41 to move. However, when it is necessary to adjust the rotational speed of the turntable 41, the rotational speed of the force output end of the reducer 432 can also be adjusted, thereby adjusting the rotational speed of the turntable 41. Thus, the turntable 41 can perform a rotational motion at a specific rotational speed.

[0067] When it is necessary to adjust the height of the mounting disk 2, start the telescopic assembly 52. In this embodiment, since the telescopic assembly 52 is set as an electric telescopic rod, the force of the electric telescopic rod can be continuously output to the bottom of the rotating box 42, thereby driving the rotating box 42 to perform a lifting motion. As the rotating box 42 performs a lifting motion, the rotating box 42 will continuously transmit the force to the connecting platform 1, and further enable the connecting platform 1 to generate a lifting motion. At this time, the connecting platform 1 will drive the mounting disk 2 located within the cavity 13 to move synchronously. Thus, the satellite communication antenna located on the mounting disk 2 can generate a lifting motion. In this way, the satellite communication antenna can be adjusted in multiple dimensions, so as to perform multi-dimensional tests to ensure that the satellite communication antenna can reach the best working state before actual deployment.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
