[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] As Figure 1 shown, in order to solve the technical problem of "how to adjust the relative distance and relative position between multiple array antennas according to different usage requirements", the structure and function of a communication array antenna will be described in detail below;

[0031] A communication array antenna includes a plurality of telescopic brackets 12 arranged in sequence. Each telescopic bracket 12 is rotatably connected with a first lead screw 13. The thread pitches of the two ends of the first lead screw 13 in the middle are the same, and the thread pitches of the two ends of each of the first lead screws 13 on both sides of the middle are different. The helical directions of the multiple first lead screws 13 are opposite to each other. The multiple first lead screws 13 are connected to each other in pairs through universal joints 14. A power mechanism I for driving one of the first lead screws 13 to rotate is fixedly connected to the telescopic bracket 12. The power mechanism I is preferably a servo motor. A deflection bracket 21 is arranged between two adjacent telescopic brackets 12. Both sides of each deflection bracket 21 are rotatably connected with a deflection seat 22. The two deflection seats 22 are respectively threadedly connected to the first lead screws 13 at corresponding positions. A power mechanism II for driving the deflection bracket 21 to deflect is fixedly connected to each deflection seat 22. The power mechanism II is preferably a servo motor;

[0032] During use, as Figure 1As shown in the figure, it is a schematic diagram of the horizontal arrangement of the array antennas 32. When it is necessary to adjust the relative distance between multiple array antennas 32, the power mechanism I is started, and the output shaft of the power mechanism I starts to rotate. The output shaft of the power mechanism I drives the corresponding first lead screw 13 to rotate. The multiple first lead screws 13 are connected by a universal joint 14. That is, when one first lead screw 13 rotates, the multiple first lead screws 13 rotate together under the transmission of the universal joint 14. The thread pitches at both ends of the first lead screw 13 in the middle are opposite, and the helix pitches of the multiple first lead screws 13 on both sides of the middle are opposite. That is, as Figure 1 shown, at this time, there are seven first lead screws 13. The thread pitches at both ends of the first lead screw 13 in the middle, that is, the fourth first lead screw 13, are opposite, and the helix pitches of the first lead screws 13 from the first to the third are opposite to the helix pitches of the first lead screws 13 from the fifth to the seventh. Furthermore, when the multiple first lead screws 13 rotate, the multiple first lead screws 13 drive multiple deflection brackets 21 to approach or move away from each other through the threads, thereby adjusting the relative distance between multiple antenna components;

[0033] Furthermore, in order to ensure that each deflection bracket 21 can approach each other, shorten the relative distance between multiple antenna components, and ensure that the distances between multiple antenna components are shortened proportionally, thereby meeting different position adjustment requirements, the thread pitches at both ends of the first lead screw 13 in the middle are the same, and the thread pitches at both ends of each first lead screw 13 on both sides of the middle are different. The following takes Figure 1 shown as an example where there are seven first lead screws 13 for a detailed description. The first lead screw 13 in the middle, that is, the fourth first lead screw 13, has a pitch of one at both ends. Therefore, when the first lead screw 13 in the middle rotates, it pulls two deflection brackets 21 to approach each other by a distance of one pitch. The pitch of the inner end of the third and fifth first lead screws 13 is one, the pitch of the outer end of the third and fifth first lead screws 13 is two, the pitch of the inner end of the second and sixth first lead screws 13 is two, the pitch of the outer end of the second and sixth first lead screws 13 is three, the pitch of the inner end of the first and seventh first lead screws 13 is three, and the pitch of the outer end of the first and seventh first lead screws 13 is four, and so on. Furthermore, when the multiple first lead screws 13 rotate together, they will proportionally push the multiple deflection brackets 21 to approach or move away from each other. That is, when the third and fourth deflection brackets 21 approach each other by one unit, the second and fifth deflection brackets 21 approach each other by two units, and the first and sixth deflection brackets 21 approach each other by three units. Thereby, the multiple deflection brackets 21 approach or move away from each other proportionally, thereby adjusting the relative distance between multiple antenna components, and thereby meeting the adjustment in position;

[0034] Furthermore, when it is necessary to adjust the arrangement mode of multiple antenna components, that is, not as in Figure 1Instead of the horizontal arrangement shown, it forms an integral arc shape. That is, when the whole is arranged into a convex surface or a concave surface, the power mechanism II is activated, and the output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the deflection bracket 21 to rotate. That is, activating the power mechanism II at the corresponding position can adjust the corresponding deflection bracket 21 to deflect. Furthermore, the deflection bracket 21 deflects, driving the telescopic bracket 12 to deflect. When multiple telescopic brackets 12 and deflection brackets 21 deflect together, the distribution mode of the overall arrangement of the antenna components is adjusted, making multiple antenna components concave inward or convex outward. At the same time, since multiple first lead screws 13 are connected through a universal joint 14, when the deflection bracket 21 deflects and drives the telescopic bracket 12 to deflect, the multiple first lead screws 13 can still transmit power;

[0035] Each deflection bracket 21 is rotatably connected with an antenna component. The antenna component includes a rotating frame 31 and two array antennas 32 hinged on the rotating frame 31. A power mechanism III for driving the rotating frame 31 to rotate is fixedly connected to the deflection bracket 21. The power mechanism III is preferably a servo motor. A power mechanism IV for driving the array antenna 32 to rotate is fixedly connected to the rotating frame 31. The power mechanism IV is preferably a servo motor;

[0036] Furthermore, when it is necessary to adjust the tilt angle of each antenna component, the power mechanism III is activated, and the output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating frame 31 to rotate, thereby adjusting the deflection direction of the rotating frame 31. When it is necessary to adjust the tilt angle of each array antenna 32, the power mechanism IV is activated, and the output shaft of the power mechanism IV starts to rotate, thereby adjusting the deflection angle of each array antenna 32;

[0037] Furthermore, by activating the power mechanism I, power mechanism II, power mechanism III, and power mechanism IV, the positions and relative distances of multiple array antennas 32 are adjusted according to different usage requirements;

[0038] Furthermore, as Figures 8 to 10 shown, when it is necessary to adjust the height and vertical arrangement of multiple array antennas 32;

[0039] Connection brackets 40 are slidably connected to the telescopic brackets 12 on the front and rear sides. The connection brackets 40 are threadedly connected to the first lead screws 13;

[0040] A support ring 11 is fixedly connected to the telescopic bracket 12 in the middle. The support ring 11 is rotatably connected to the lifting bracket 66. A power mechanism V for driving the support ring 11 to rotate is fixedly connected to the lifting bracket 66. The power mechanism V is preferably a servo motor;

[0041] The lifting bracket 66 is slidably connected to the sliding cylinder 65. The sliding cylinder 65 is fixedly connected to the mounting bracket 61. A third lead screw 62 is rotatably connected to the mounting bracket 61. A power mechanism VI for driving the third lead screw 62 to rotate is fixedly connected to the mounting bracket 61. The power mechanism VI is preferably a servo motor. The thread directions at both ends of the third lead screw 62 are opposite. Both ends of the third lead screw 62 are threadedly connected with extrusion sliders 63. Two extrusion connecting rods 64 are hinged between the two extrusion sliders 63 and the lifting bracket 66;

[0042] During use, start the power mechanism VI. The output shaft of the power mechanism VI starts to rotate. The output shaft of the power mechanism VI drives the third lead screw 62 to rotate. When the third lead screw 62 rotates, it drives the two extrusion sliders 63 to move through the threads, causing the two extrusion sliders 63 to approach each other and then push the two extrusion connecting rods 64 to move. The two extrusion connecting rods 64 squeeze the lifting bracket 66, thereby adjusting the height of the lifting bracket 66 and further adjusting the overall height of the multiple array antennas 32;

[0043] Furthermore, start the power mechanism V. The output shaft of the power mechanism V starts to rotate. The output shaft of the power mechanism V drives the support ring 11 to rotate. The support ring 11 drives the multiple telescopic brackets 12 to rotate, thereby making the multiple antenna components arranged vertically;

[0044] Furthermore, when it is necessary to move the multiple array antennas 32;

[0045] The mounting bracket 61 is fixedly connected to the device bracket 51. A second lead screw 52 is rotatably connected to the device bracket 51. Both ends of the second lead screw 52 are threadedly connected to the adjustment bracket 53. The adjustment bracket 53 is slidably connected to the device bracket 51. A swing bracket 54 is rotatably connected to the adjustment bracket 53. A support wheel 55 is rotatably connected to the swing bracket 54. A power mechanism VII for driving the swing bracket 54 to rotate is fixedly connected to the adjustment bracket 53. The power mechanism VII is preferably a servo motor. A power mechanism VIII for driving the support wheel 55 to rotate is fixedly connected to the swing bracket 54. The power mechanism VIII is preferably a servo motor;

[0046] Start the power mechanism VIII. The output shaft of the power mechanism VIII drives the support wheels 55 to rotate. The rotation of the two support wheels 55 drives the movement of multiple array antennas 32, adjusting the positions of the multiple array antennas 32. Further, rotate the second lead screw 52. When the second lead screw 52 rotates, it drives the adjustment bracket 53 to move through the thread, thereby adjusting the position of the support wheels 55, and further adjusting the support positions of the two support wheels 55 for the multiple array antennas 32, making the support of the device stable. Further, start the power mechanism VII. The output shaft of the power mechanism VII drives the swing bracket 54 to move. The swing bracket 54 drives the support wheels 55 to move, thereby adjusting the contact state of the support wheels 55 with the ground, that is, whether the two support wheels 55 support the device or drive the device to move.
