Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and in particular to an antenna with multi-axis angle adjustment. Background Technology

[0002] An antenna is a device in a radio transceiver system that radiates or receives electromagnetic waves into or from space. It is an essential part of radio communication systems. When a high-frequency current flows through a conductor, an electric field and a magnetic field are generated in the surrounding space. If the conductor is split in a straight line, the currents on the terminal conductors are in phase, and their radiated fields at points in space are superimposed in phase, forming an effective radiation system. During reception, the electromagnetic wave acts on the antenna element, inducing an electromotive force on the element. If the antenna is connected to a receiving device, a high-frequency current will be generated at the input of the receiving device.

[0003] The above-mentioned and existing technologies have the following drawbacks: When using antennas outdoors, the fixed structure of the antenna mounting bracket results in a fixed angle of the antenna during operation, making it difficult to adapt to the needs of different signal directions and different installation scenarios, leading to a decrease in signal transmission and reception efficiency.

[0004] Therefore, an antenna with multi-axis angle adjustment is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the fixed antenna mounting bracket structure results in a fixed antenna angle during operation, making it difficult to adapt to different signal directions and installation scenarios. Therefore, this invention proposes an antenna with multi-axis angle adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an antenna with multi-axis angle adjustment, comprising a base, a connecting column rotatably connected to the upper end of the base, a lifting column slidably connected to the inner circumferential surface of the connecting column, a bracket fixedly mounted on the upper end of the lifting column, a plurality of rotating plates rotatably connected to the surface of the bracket, a mounting plate rotatably connected to the surface of the rotating plates, a communication antenna fixedly mounted on the surface of the mounting plate, a sliding tube slidably sleeved on the outer circumferential surface of the lifting column, a transmission plate rotatably connected to the outer circumferential surface of the sliding tube, the transmission plate rotatably connected to the rotating plates, a first electric push rod fixedly mounted on the inner circumferential surface of the lifting column, a connecting plate fixedly mounted on the output end of the first electric push rod, a through hole opened on the lifting column relative to the connecting plate, the connecting plate passing through the through hole and fixedly connected to the sliding tube, a second electric push rod rotatably connected to the surface of the rotating plates, and the output end of the second electric push rod rotatably connected to the mounting plate.

[0007] The effects achieved by the above components are as follows: by setting up components such as brackets, mounting plates, first electric actuators, connecting plates, and second electric actuators, during the outdoor use of communication antennas, the combination of coarse and fine adjustments ensures that the communication antenna can transmit and receive signals at the optimal elevation angle, thereby improving signal transmission and reception efficiency. Furthermore, it can simultaneously adjust the angles of multiple communication antennas to ensure adjustment efficiency, while also allowing for adjustment of the angle of a single communication antenna to ensure adjustment flexibility.

[0008] Preferably, two positioning rings are fixedly mounted on the outer circumference of the lifting column, and the sliding tube is located between the two positioning rings.

[0009] The effect achieved by the above components is that the slide tube is located between the two positioning rings, which can prevent overtravel.

[0010] Preferably, a servo motor is fixedly mounted on the inner circumferential surface of the connecting column, and a lead screw is fixedly mounted on the output end of the servo motor, the lead screw being threadedly connected to the lifting column.

[0011] The effect achieved by the above components is as follows: the servo motor is started, the servo motor drives the lead screw to rotate, and the lead screw will drive the lifting column to move in the vertical direction through the thread.

[0012] Preferably, a guide block is fixedly mounted on the outer circumferential surface of the lifting column, and a guide groove is provided on the inner circumferential surface of the connecting column, with the guide block and the guide groove being slidably connected.

[0013] The effect achieved by the above components is that, since the guide block is slidably connected to the guide groove, the guide block can restrict the lifting column from rotating synchronously with the lead screw, so that the rotation of the lead screw is converted into the linear movement of the lifting column along the axis of the connecting column.

[0014] Preferably, a fixing plate is fixedly mounted on the outer circumferential surface of the base, a drive motor is fixedly mounted on the upper surface of the fixing plate, a worm gear is fixedly mounted on the output end of the drive motor, the worm gear is rotatably connected to the base, and a worm wheel is fixedly mounted on the inner circumferential surface of the connecting column, with the worm gear meshing with the worm wheel.

[0015] The effect achieved by the above components is as follows: when the drive motor is started, the drive motor drives the worm to rotate inside the base. Since the worm meshes with the worm wheel, the rotation of the worm will drive the worm wheel to rotate synchronously, which in turn drives the connecting column fixed to the worm wheel to rotate around the base. At this time, the communication antenna will rotate horizontally together with the connecting column, and finally realize the adjustment of the horizontal angle of the communication antenna to adapt to signal sources in different directions.

[0016] Preferably, a protective plate is detachably mounted on the surface of the fixing plate, and the drive motor is located inside the protective plate.

[0017] The effect achieved by the above components is that the protective plate encloses the drive motor, preventing falling objects from damaging the drive motor.

[0018] Preferably, both ends of the protective plate are fixedly fitted with water baffles.

[0019] The above-mentioned components achieve the following effect: the water baffles at both ends of the protective plate can prevent rainwater from entering and avoid corrosion and damage to the drive motor caused by direct dripping of outdoor rainwater.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up components such as a bracket, mounting plate, first electric actuator, connecting plate, and second electric actuator, the communication antenna can be used outdoors. Through a combination of coarse and fine adjustment, the communication antenna can be ensured to transmit and receive signals at the optimal elevation angle, thereby improving signal transmission and reception efficiency. Furthermore, it can simultaneously adjust the angles of multiple communication antennas to ensure adjustment efficiency, while also allowing for adjustment of the angle of a single communication antenna to ensure adjustment flexibility.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-6 As shown, this utility model provides an antenna with multi-axis angle adjustment, including a base 1, a connecting column 2 rotatably connected to the upper end of the base 1, a lifting column 3 slidably connected to the inner circumferential surface of the connecting column 2, a bracket 4 fixedly mounted on the upper end of the lifting column 3, several rotating plates 24 rotatably connected to the surface of the bracket 4, a mounting plate 5 rotatably connected to the surface of the rotating plates 24, a communication antenna 6 fixedly mounted on the surface of the mounting plate 5, a sliding tube 7 slidably sleeved on the outer circumferential surface of the lifting column 3, a transmission plate 8 rotatably connected to the outer circumferential surface of the sliding tube 7, the transmission plate 8 rotatably connected to the rotating plates 24, a first electric push rod 9 fixedly mounted on the inner circumferential surface of the lifting column 3, a connecting plate 10 fixedly mounted on the output end of the first electric push rod 9, and a lifting... A through hole 11 is provided on the column 3 relative to the position of the connecting plate 10. The connecting plate 10 passes through the through hole 11 and is fixedly connected to the slide tube 7. The surface of the rotating plate 24 is rotatably connected to the second electric push rod 12. The output end of the second electric push rod 12 is rotatably connected to the mounting plate 5. By setting up components such as the bracket 4, mounting plate 5, first electric push rod 9, connecting plate 10 and second electric push rod 12, during the outdoor use of the communication antenna 6, the combination of coarse adjustment and fine adjustment ensures that the communication antenna 6 can transmit and receive signals at the best elevation angle, improves the signal transmission and reception efficiency, and can adjust the angle of multiple communication antennas 6 at the same time to ensure adjustment efficiency, and can also adjust the angle of a single communication antenna 6 to ensure adjustment flexibility.

[0026] like Figures 2-5 As shown, two positioning rings 13 are fixedly mounted on the outer circumference of the lifting column 3. The slide tube 7 is located between the two positioning rings 13, which can prevent overtravel. A servo motor 14 is fixedly mounted on the inner circumference of the connecting column 2. A lead screw 15 is fixedly mounted on the output end of the servo motor 14. The lead screw 15 is threadedly connected to the lifting column 3. When the servo motor 14 is started, the servo motor 14 drives the lead screw 15 to rotate. The lead screw 15 will drive the lifting column 3 to move vertically by means of the thread. A guide block 16 is fixedly mounted on the outer circumference of the lifting column 3. A guide groove 17 is opened on the inner circumference of the connecting column 2. The guide block 16 is slidably connected to the guide groove 17. Since the guide block 16 is slidably connected to the guide groove 17, the guide block 16 can restrict the lifting column 3 to rotate synchronously with the lead screw 15, so that the rotation of the lead screw 15 is converted into the linear movement of the lifting column 3 along the axis of the connecting column 2.

[0027] like Figures 5-6As shown, a fixing plate 18 is fixedly mounted on the outer circumferential surface of the base 1. A drive motor 19 is fixedly mounted on the upper surface of the fixing plate 18. A worm 20 is fixedly mounted on the output end of the drive motor 19. The worm 20 is rotatably connected to the base 1. A worm wheel 21 is fixedly mounted on the inner circumferential surface of the connecting column 2. The worm 20 and the worm wheel 21 mesh. When the drive motor 19 is started, it drives the worm 20 to rotate within the base 1. Since the worm 20 meshes with the worm wheel 21, the rotation of the worm 20 drives the worm wheel 21 to rotate synchronously, thereby driving the connecting column 2, which is fixed to the worm wheel 21, to rotate around the base. 1. Rotate. At this time, the communication antenna 6 will rotate horizontally together with the connecting column 2, and finally realize the adjustment of the horizontal angle of the communication antenna 6 to adapt to the signal source in different directions. The surface of the fixing plate 18 is detachably equipped with a protective plate 22. The drive motor 19 is located inside the protective plate 22. The protective plate 22 wraps the drive motor 19 to prevent falling objects from damaging the drive motor 19. Both ends of the protective plate 22 are fixedly equipped with water baffles 25. The water baffles 25 at both ends of the protective plate 22 can block rainwater from entering and prevent the drive motor 19 from being corroded and damaged by direct dripping of outdoor rainwater.

[0028] The overall working principle is as follows: when it is necessary to adjust the horizontal orientation of the communication antenna 66, the drive motor 1919 is started. The drive motor 1919 drives the worm 20 to rotate inside the base 11. Since the worm 20 meshes with the worm wheel 2121, the rotation of the worm 20 will drive the worm wheel 2121 to rotate synchronously, thereby driving the connecting column 2 fixed to the worm wheel 21 to rotate around the base 1. At this time, the communication antenna 6 will rotate horizontally together with the connecting column 2, thus realizing the adjustment of the horizontal angle of the communication antenna 6 to adapt to signal sources in different directions. The protective plate 22 encloses the drive motor 19 to prevent falling objects from damaging the drive motor 19. The water baffles 25 at both ends of the protective plate 22 can block rainwater from entering and prevent the drive motor 19 from being corroded and damaged by direct dripping outdoor rainwater.

[0029] When the height of the communication antenna 6 needs to be adjusted according to the outdoor installation scenario, the servo motor 14 is started. The servo motor 14 drives the lead screw 15 to rotate. Since the guide block 16 is slidably connected to the guide groove 17, the guide block 16 can restrict the lifting column 3 to rotate synchronously with the lead screw 15, so that the rotation of the lead screw 15 is converted into the linear movement of the lifting column 3 along the axis of the connecting column 2. The communication antenna 6 will rise and fall together with the lifting column 3, thereby realizing the adjustment of the height of the communication antenna 6.

[0030] When coarse adjustment of the elevation angle of the communication antenna 6 is required, the first electric actuator 9 is activated. The output end of the first electric actuator 9 pushes the connecting plate 10 to move. The connecting plate 10 passes through the through hole 11 on the surface of the lifting column 3, causing the slide tube 7 to slide along the lifting column 3. The slide tube 7 is located between the two positioning rings 13 to avoid overtravel. When the slide tube 7 moves, it will drive the transmission plate 8 to rotate. The transmission plate 8 pushes the rotating plate 24 to rotate around the rotation point on the surface of the bracket 4. The rotating plate 24 drives the mounting plate 5 and the communication antenna 6 to rotate synchronously, realizing the initial adjustment of the elevation angle of the communication antenna 6. When fine adjustment is required... When the elevation angle of the communication antenna 6 is precisely aligned with the signal source, the second electric actuator 12 is activated. The output end of the second electric actuator 12 directly pushes the mounting plate 5 to rotate around the rotation point on the surface of the rotating plate 24. The communication antenna 6 on the mounting plate 5 rotates with the mounting plate 5, completing the fine adjustment of the elevation angle. By combining coarse and fine adjustments, it is ensured that the communication antenna 6 can transmit and receive signals at the optimal elevation angle, improving signal transmission and reception efficiency. Furthermore, it can adjust the angles of multiple communication antennas 6 simultaneously, as well as adjust the angle of a single communication antenna 6, improving the flexibility of use.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
