Abstract
Description
Technical Field
[0001] This invention relates to the field of antenna technology, specifically to large-scale MIMO array antennas. Background Technology
[0002] One of the core technologies of massive MIMO, its birth and development stemmed from the continuous upgrading needs of the wireless communication field for spectrum efficiency, system capacity, transmission reliability and coverage, as well as the performance bottleneck of traditional MIMO technology in high-frequency communication and dense networking scenarios. As the core hardware of 5G and 6G communication networks, the installation, deployment and windproof design of massive MIMO array antennas are directly related to the stable operation of the communication system, the service life of the equipment and the safety of operation and maintenance. The technical requirements of both stem from the structural characteristics of massive MIMO itself, the constraints of deployment scenarios, and the reliability requirements of communication infrastructure.
[0003] In practical applications, existing large-scale MIMO array antennas face structural risks in strong wind environments. Due to their large array size and wide windward area, strong winds will generate continuous and concentrated loads on the rigid structure. When the load exceeds the structural tolerance limit, it is easy to cause the rigid components such as brackets and connectors to break, directly threatening the safety of the equipment and the stability of base station operation and maintenance. Meanwhile, strong winds can also cause the antenna azimuth and downtilt angles to shift, and even deform the position of array elements, destroying the original precise beam pointing design. Such shifts and deformations are often difficult to recover through simple adjustments, ultimately causing abnormal signal transmission that cannot be restored, seriously affecting the quality of communication services. To address this, we propose a new large-scale MIMO array antenna. Summary of the Invention
[0004] One of the technical problems to be solved in this application is: designing a large-scale MIMO array antenna that can automatically reset after encountering strong winds.
[0005] To solve the above technical problems, this application provides a massive MIMO array antenna, including a mounting rod, a mounting plate and signal units. The mounting rod has two locking claws on its outer side, and the mounting plate has an upper folding plate on its outer side. A horizontal reset component is provided between one of the locking claws and the upper folding plate, the function of which is to enable the mounting plate and the signal units it carries to automatically reset in the horizontal direction. The mounting plate has a movably folded lower plate on its outer side, a connecting groove on its side, a connecting plate on its side, a rotating rod connected to the inner side of the connecting plate and the connecting groove, and a lateral reset assembly between the other locking claw and the lower folded lower plate to drive the mounting plate and its signal unit to reset laterally.
[0006] In some embodiments, the lateral reset assembly includes a rotating plate disposed on the side of the lower folding plate, a connecting shell disposed on the side of another locking claw, a connecting clamp disposed on the side of the connecting shell, and the rotating plate being movably disposed inside the connecting clamp.
[0007] In some embodiments, the bottom of the connecting clamp is provided with a limiting rod that penetrates the connecting clamp and the rotating plate, and the bottom end of the limiting rod is provided with a limiting plate that fits tightly against the bottom of the connecting clamp.
[0008] In some embodiments, an electric telescopic rod is provided on the inner side of the connecting shell, and a slider is provided at the output end of the electric telescopic rod. Both sides of the slider are movably disposed on the inner side of the connecting shell, and a moving block is provided on the side of the slider away from the electric telescopic rod. A V-shaped groove is formed on the side of the moving block.
[0009] In some embodiments, a horizontal plate is provided on the side of the rotating plate, and a wedge is provided on the inner side of the connecting shell, with the outer side of the wedge being movably disposed on the inner wall of the V-groove.
[0010] In some embodiments, a pressure adjusting member is provided on the outer side of the limiting rod to adjust the resistance to rotation of the rotating plate when it rotates. The pressure adjusting member includes an arched plate disposed on the top of the connecting shell. The arched plate is sleeved on the outer side of the limiting rod. A screw rod penetrating the arched plate is provided at the top of the limiting rod. A nut that fits tightly against the arched plate is threaded onto the outer side of the screw rod.
[0011] In some embodiments, two compression rings are sleeved on the outer side of the limiting rod, and a second spring is provided between the two compression rings. The ends of the two compression rings are respectively tightly attached to the inner side of the arched plate and the top of the rotating plate.
[0012] In some embodiments, the horizontal reset assembly includes a fixing rod disposed on the side of the upper folding plate, an installation ball disposed at the end of the fixing rod, a connecting rod disposed on the side of one of the locking claws, a gas controller disposed at the end of the connecting rod, an internally connected air cylinder disposed at the end of the gas controller, a sliding rod movably disposed on the inner side of the air cylinder, a movable column disposed at the end of the sliding rod, and the installation ball movably embedded in the inner side of the movable column.
[0013] In some embodiments, a piston is provided at the end of the slide rod inside the air cylinder, a spring is sleeved on the outside of the slide rod, the end of the spring is located at the end of the piston, and a pressure detector communicating with the inside is provided on the outside of the air cylinder.
[0014] This invention has at least the following beneficial effects: 1. By setting up horizontal and lateral reset components, the mounting plate and signal unit can be reset in the horizontal and lateral directions respectively. This can buffer the continuous concentrated load of strong winds on the rigid structure, prevent the brackets and connectors from breaking due to the load exceeding the tolerance limit, reduce the probability of equipment damage, ensure the stability of base station operation and maintenance, reduce safety hazards caused by structural fracture, and extend the overall service life of large-scale MIMO array antennas. 2. Strong winds can easily cause antenna azimuth and downtilt angle shifts and array unit deformations, leading to abnormal signal transmission that cannot be restored. The reset component of this device can drive the mounting plate to automatically reset the signal unit, correcting beam pointing deviations without complex manual adjustments. This effectively solves the problem of signal recovery after traditional antenna offset and deformation, continuously maintaining accurate beam pointing design and ensuring stable communication service quality.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1: Please refer to Figure 1-8 This invention provides a technical solution: a massive MIMO array antenna, including a mounting rod 1, a mounting plate 2, and a signal unit 3. The mounting rod 1 has two locking claws 7 on its outer side, and the mounting plate 2 has an upper folding plate 4 on its outer side. A horizontal reset component 8 is provided between one of the locking claws 7 and the upper folding plate 4. Its function is to enable the mounting plate 2 and the signal unit 3 it carries to automatically reset in the horizontal direction. The two ends of the component are respectively hinged to the locking claw 7 and the upper folding plate 4. Its core function is to drive the mounting plate 2 and the signal unit 3 to automatically reset after the mounting plate 2 is horizontally offset by strong wind, so as to maintain the horizontal attitude of the signal unit 3. A lower folding plate 5 is movably provided on the outer side of the mounting plate 2. A connecting groove 10 is provided on the side of the mounting plate 2. A connecting plate 9 is provided on the side of the lower folding plate 5. A rotating rod 11 connected to the inner side of the connecting groove 10 is provided on the inner side of the connecting plate 9. A horizontal reset component 6 is provided between another locking claw 7 and the lower folding plate 5 to drive the mounting plate 2 and its signal unit 3 to reset horizontally.
[0019] The lateral reset assembly 6 includes a rotating plate 64 disposed on the side of the lower folding plate 5, a connecting shell 61 disposed on the side of another locking claw 7, and a connecting clamp 62 disposed on the side of the connecting shell 61. The rotating plate 64 is movably disposed inside the connecting clamp 62. The connecting shell 61 is fixed to the side of the other locking claw 7 by bolts. The connecting clamp 62 is integrally formed on the side of the connecting shell 61. The rotating plate 64 is movably embedded inside the connecting clamp 62 and can rotate around the subsequent limiting rod 65. This structure provides basic support for lateral reset, ensures stable movement of the rotating plate 64 under strong winds, and transmits reset power.
[0020] The bottom of the connecting clamp 62 is provided with a limiting rod 65 that passes through the connecting clamp 62 and the rotating plate 64. The bottom end of the limiting rod 65 is provided with a limiting plate 66 that fits tightly against the bottom of the connecting clamp 62. The limiting rod 65 passes through the connecting clamp 62 and the rotating plate 64 in sequence, and the limiting plate 66 is welded to its bottom end. The diameter of the limiting plate 66 is larger than that of the limiting rod 65 and fits tightly against the bottom of the connecting clamp 62. The limiting rod 65 restricts the rotating plate 64 to rotate only around it, and the limiting plate 66 prevents the limiting rod 65 from falling off, avoids axial displacement of the rotating plate 64, and ensures the structural stability of lateral reset.
[0021] An electric telescopic rod 63 is provided on the inner side of the connecting shell 61. A slider 68 is provided at the output end of the electric telescopic rod 63. Both sides of the slider 68 are movably disposed on the inner side of the connecting shell 61. A moving block 69 is provided on the side of the slider 68 away from the electric telescopic rod 63. A V-groove 610 is formed on the side of the moving block 69. The two sides of the slider 68 are embedded in the slide rails on the inner wall of the connecting shell 61, and can slide linearly along the slide rails. The moving block 69 is bolted to the side of the slider 68 away from the electric telescopic rod 63. The moving block 69 has an embedded V-groove 610 on its side, which is used to cooperate with the subsequent wedge block 611 to convert linear power into rotational power.
[0022] A horizontal plate 67 is provided on the side of the rotating plate 64. The horizontal plate 67 extends to the inner side of the connecting shell 61 and a wedge 611 is provided. The outer side of the wedge 611 is movably disposed on the inner wall of the V-groove 610. The shape of the wedge 611 matches the V-groove 610, and the outer side slides against the inner wall of the V-groove 610. When the moving block 69 moves with the slider 68, the V-groove 610 squeezes the wedge 611, causing the horizontal plate 67 to rotate, which in turn drives the rotating plate 64 to rotate. The lower folding plate 5 drives the mounting plate 2 to complete the lateral reset.
[0023] A pressure adjusting component 12 is provided on the outer side of the limiting rod 65 to adjust the rotational resistance of the rotating plate 64 when it rotates. The pressure adjusting component 12 includes an arched plate 121 located on the top of the connecting shell 61. The arched plate 121 is sleeved on the outer side of the limiting rod 65. A screw 122 is provided at the top of the limiting rod 65, penetrating the arched plate 121. A nut 123 that fits tightly against the arched plate 121 is threadedly connected to the outer side of the screw 122. The arched plate 121 is bolted to the top of the connecting shell 61. The screw 122 at the top of the limiting rod 65 penetrates the arched plate 121. The nut 123 that fits tightly against the arched plate 121 is threadedly connected to the outer side of the screw 122. Rotating the nut 123 can adjust the tightness of the arched plate 121, change the pressure on the lower components, and adapt to areas with different airflow.
[0024] Two compression rings 124 are sleeved on the outer side of the limiting rod 65. A second spring 125 is arranged between the two compression rings 124. The ends of the two compression rings 124 are tightly attached to the inner side of the arched plate 121 and the top of the rotating plate 64, respectively. The second spring 125 is arranged between the two compression rings 124. The two ends of the second spring 125 are fixedly connected to the compression rings 124. The upper compression ring 124 is attached to the inner side of the arched plate 121, and the lower compression ring 124 is attached to the top of the rotating plate 64. The second spring 125 generates compression force through elastic deformation, which is transmitted to the rotating plate 64 through the compression rings 124 to form rotational resistance, so as to prevent the rotating plate 64 from moving erroneously when the air volume is small.
[0025] Example 2: Please refer to Figure 7-8 The present invention provides a technical solution: the horizontal reset assembly 8 includes a fixing rod 82 disposed on the side of the upper folding plate 4, a mounting ball 83 disposed at the end of the fixing rod 82, a connecting rod 81 disposed on the side of one of its locking claws 7, a gas controller 87 disposed at the end of the connecting rod 81, an internally connected air cylinder 86 disposed at the end of the gas controller 87, a sliding rod 89 movably disposed on the inner side of the air cylinder 86, a moving column 85 disposed at the end of the sliding rod 89, the mounting ball 83 being movably embedded in the inner side of the moving column 85, the connecting rod 81 being bolted to the side of one of its locking claws 7, the gas controller 87 being mounted on the end of the connecting rod 81, the end of the gas controller 87 being connected to the air cylinder 86, the sliding rod 89 being movably disposed on the inner side of the air cylinder 86, the moving column 85 being welded to the end of the sliding rod 89, and the mounting ball 83 being embedded in the inner groove of the moving column 85, allowing for multi-angle rotation.
[0026] A piston 810 is provided at the end of the slide rod 89 inside the air cylinder 86. A spring 88 is sleeved on the outside of the slide rod 89, with the end of the spring 88 set at the end of the piston 810. A pressure detector 84 connected to the inside is provided on the outside of the air cylinder 86. The piston 810 slides and seals with the inner wall of the air cylinder 86. The spring 88 is sleeved on the outside of the slide rod 89, with the end of the spring 88 abutting against the piston 810 and the other end fixed to the inner wall of the air cylinder 86. The pressure detector 84 connected to the inside is installed on the outside of the air cylinder 86 and can monitor the air pressure inside the air cylinder 86 in real time, providing data for the start and stop of the gas controller 87 and ensuring accurate triggering of horizontal reset.
[0027] Working principle: When using this device, firstly, when the wind speed is too high, in order to protect the mounting plate 2 and signal unit 3 so that they can work normally afterward, they need to move. At this time, the mounting plate 2 will rotate around the connecting plate 9, causing the upper folding plate 4 to pull the fixing rod 82 to move. The fixing rod 82 will drive the mounting ball 83 to move, and the mounting ball 83 will drive the moving column 85 to move. The mounting ball 83 will rotate inside the moving column 85. At this time, the moving column 85 will drive the sliding rod 89 to move, and the sliding rod 89 will drive the piston 810 to slide inside the air cylinder 86. At this time, the piston 810 will compress the spring 88 and deform. The air pressure detector 84 will detect that the air pressure inside the air cylinder 86 is abnormal. However, in windy weather, the gas controller 87 does not work. When the mounting plate 2 and signal unit 3 move laterally, the lower folding plate 5 and rotating plate 64 will rotate around the limit rod 65, causing the horizontal plate 67 to drive the wedge block 611 to rotate. Since the rotating plate 64 will be squeezed by the second spring 125 and the compression ring 124 when rotating, it will not move when the air volume is small. The tightness of the arched plate 121 can be adjusted by rotating the nut 123 according to the local air volume, so that the rotating plate 64 is subjected to different squeezing forces by the compression ring 124 and the second spring 125, thereby completing the adjustment.
[0028] After the strong wind subsides, in order to restore the signal to normal, the electric telescopic rod 63 will drive the slider 68 to slide on the inner wall of the connecting shell 61. The slider 68 will drive the moving block 69 to move, and the moving block 69 will drive the V-groove 610 to approach the wedge block 611, so that the wedge block 611 is completely matched with the V-groove 610. This allows the mounting plate 2 and the signal unit 3 to be reset to their original positions. At this time, the gas controller 87 will work to discharge or draw in the air pressure inside the air cylinder 86. Then, after being detected by the air pressure detector 84, the mounting plate 2 and the signal unit 3 will be reset after entering a certain air pressure setting range.
