Description

Technical Field

[0001] The present invention relates to the technical field of communication antennas, and in particular to a mobile communication antenna structure. Background Art

[0002] Mobile communication antennas are an important part of communication systems. They are responsible for converting electrical signals into electromagnetic waves in space. Their performance directly affects the coverage, signal quality and system capacity of the communication system.

[0003] The publication number is CN112002981A, which is an electrically controlled and adjustable mobile communication antenna, comprising a base, a connecting rod and an antenna. The base is connected and fixed to an external device, and the connecting rod connects the base and the antenna. A hydraulic adjustment mechanism is provided in the base to drive the connecting rod, and the connecting rod drives the antenna to turn, thereby adjusting the antenna phase and sector. The fixed sleeve and the movable sleeve of the hydraulic adjustment mechanism are connected by a reinforcement sleeve with a telescopic structure. When the movable sleeve is extended, the reinforcement sleeve can prevent the movable sleeve from tilting and affecting the adjustment accuracy. An electronic compass is built in the antenna, and the system adjusts the angle through the real-time feedback position information of the electronic compass. The electrically controlled and adjustable mobile communication antenna has a reasonable structure, is easy to use, safe and reliable, and effectively solves the problem of small adjustment range of existing 5G electrically adjustable antennas.

[0004] When the above structure is in use, it is difficult to clean the antenna. If the antenna is exposed to the outdoors for a long time, impurities will adhere to the outer wall. The presence of impurities on the antenna will affect the signal transmission quality. If there are conductive impurities on the antenna (such as fallen leaves, dust, etc.), these substances may change the effective conductive area of ​​the antenna, resulting in signal attenuation or reflection loss. Impurities may cause phase and amplitude changes of the signal, thereby causing signal distortion, especially in high-frequency signals (such as 5G frequency bands). Summary of the invention

[0030] Two cleaning assemblies are symmetrically arranged on both sides of the top seat 4, and the cleaning assemblies include a fixing frame 7, a motor 8 and a fixing frame 7. Positioning shafts rotatably connected to the fixing frame 7 are arranged at both ends of the fixing frame 7, and toothed discs 11 are fixedly arranged at both ends of the positioning shaft. The motor 8 is fixed on the fixing frame 7, and a cleaning shaft 9 located on both sides of the antenna body 6 is arranged at the output end of the motor 8, and a brush 10 contacting the antenna body 6 is arranged on the cleaning shaft 9. A second telescopic assembly 16 is arranged at the lower end of the top seat 4, a slide groove 14 is arranged inside the top seat 4, and a driving frame 12 is arranged on the peripheral side of the top seat 4. Slide blocks 15 slidably matched with the slide groove 14 are arranged on both sides of the driving frame 12, and a second lifting rod connected to the slide block 15 is arranged at the output end of the second telescopic assembly 16, and toothed plates 13 are fixedly arranged at the four corners of the driving frame 12, and the toothed plates 13 are meshed with the corresponding toothed discs 11;

[0031] When the structure is used, the base 1 is fixed at a designated position, and the first lifting assembly 24 is started, so that the first lifting rod can drive the second branch pipe 3 to move up and down on the first branch pipe 2, so as to conveniently temporarily adjust the height of the antenna body 6;

[0032] After the antenna body 6 has been used for a period of time, the motor 8 is started, so that the cleaning shaft 9 can drive the brush 10 to rotate. At this time, the brush 10 can clean the outer wall of the antenna body 6. Further starting the second telescopic component 16 can make the slider 15 slide in the slide groove 14, so that the driving frame 12 can be lifted and lowered on the peripheral side of the top seat 4, and then the tooth plate 13 can be lifted and lowered.

[0033] In this embodiment, the first lifting assembly 24 and the second telescopic assembly 16 can both be telescopic cylinders, and the motor 8 can be a servo motor.

[0034] In this embodiment, a limit plate is provided below the top seat 4, and the limit plate can rotate at the top of the second branch pipe 3. A rotating shaft 17 is rotatably provided at the bottom of the first branch pipe 2, and a driving block 18 located inside the first branch pipe 2 is provided at one end of the rotating shaft 17. A first limit frame 21 is fixedly provided inside the first branch pipe 2, and a second limit frame 22 is fixedly provided inside the second branch pipe 3. A first butt joint pipe 19 is rotatably provided on the first limit frame 21, and a second butt joint pipe 20 is rotatably provided on the second limit frame 22. The top end of the second butt joint pipe 20 is connected to the limit plate, and the bottom end of the second butt joint pipe 20 is butt jointed with the first butt joint pipe 19. A driven block 23 meshing with the driving block 18 is provided at the bottom end of the first butt joint pipe 19, and a butt joint groove 26 is provided inside the first butt joint pipe 19. The lower end of the tube 20 is provided with a docking block 25 inserted into the docking groove 26. When the base 1 is placed, the rotating shaft 17 is rotated, so that the driving block 18 can drive the driven block 23 to rotate through the meshing effect, so that the first docking tube 19 can drive the second docking tube 20 to rotate, and then the limiting plate can drive the top seat 4 and the vertical rod 5 to rotate, so as to facilitate the temporary adjustment of the angle of the antenna body 6. In this process, the second docking tube 20 can be limited by the second limiting frame 22, and the first docking tube 19 can be limited by the first limiting frame 21.

Through the cooperation of the docking block 25 and the docking groove 26, the stability of the first docking tube 19 and the second docking tube 20 during docking can be improved.

[0035] There is no limiting structure at the rotating shaft 17. When the rotating shaft 17 is subjected to external force, it is easy to rotate by itself. A limiting seat penetrated by the rotating shaft 17 is provided at the bottom of the first branch pipe 2. An anti-skid ring penetrated by the rotating shaft 17 is provided on the limiting seat. There are multiple anti-skid rings, and the anti-skid rings are made of anti-skid rubber rings. The anti-skid rings can provide a friction force to the rotating shaft 17, so that the rotating shaft 17 is not easy to rotate by itself after being subjected to external force.

[0036] In this embodiment, the limit plate is fixed below the top seat 4 through a support rod. The limit plate and the support rod are fixed by screws. The screw fixing method has the advantage of easy assembly. The drive frame 12 and the tooth plate 13 can be an integrated structure.
