Description

Technical Field

[0001] The invention relates to the field of communication equipment, in particular to an antenna electronic downtilt angle adjustment component and an adjustment method thereof. Background Art

[0002] The coverage of the antenna is achieved through the vertical main beam, and the adjustment of the downtilt angle changes the coverage range of the main beam. For the electrically regulated antenna, the phase of the power signal obtained by each radiating unit (diopter) in the antenna array is changed by a phase shifter to achieve the downtilt of the vertical main beam. It is the application of radar phased array technology in mobile communications. The principle of electronic downtilt is to change the phase of the diopter of the colinear array antenna, change the amplitude of the vertical component and the horizontal component, and change the field strength of the synthetic component, so as to make the vertical radiation pattern of the antenna downtilt. Since the field strength in all directions of the antenna increases and decreases at the same time, it is ensured that the antenna radiation pattern does not change much after changing the tilt angle, so that the coverage distance in the main lobe direction is shortened, and at the same time, the entire directional pattern reduces the coverage area in the service cell sector without causing interference.

[0003] Electronic downtilt is achieved by adjusting the coil inside the antenna to adjust the signal downtilt angle. It is achieved by adjusting the antenna array. Electronic downtilt is also divided into fixed electronic downtilt and remote electronic adjustment. Remote electronic adjustment is very necessary in countries with widely distributed power grids or high labor costs.

[0004] Electrically adjustable antennas generally achieve changes in the vibrator path by adjusting the vibrator circuit through the physical structure of the motor; this is the phase shifter, which changes the feeding phase of each vibrator by adjusting the length of the feeding network to achieve antenna beam downtilt.

[0005] Currently, there are two ways to change the phase of the output signal of the base station antenna: using RCU for electric adjustment or directly manually adjusting the phase shifter. If the base station antenna is manually adjusted (without built-in RCU), special tools are required to adjust the downtilt angle. If you want to remotely adjust the downtilt angle, you must use an external RCU connection; if the base station antenna has a built-in RCU, the downtilt angle of the antenna cannot be manually adjusted. When the RCU is damaged, the downtilt angle of the base station antenna can only be adjusted after the RCU is replaced.

[0006] Therefore, the present invention provides an antenna electronic downtilt angle adjustment component and an adjustment method thereof. Summary of the invention

[0007] In view of the problems in the prior art, the purpose of the present invention is to provide an antenna electronic downtilt angle adjustment component and an adjustment method thereof, which overcomes the problems of the prior art and can achieve the coexistence of remote electrical adjustment and manual adjustment of the antenna downtilt angle.

[0069] Figure 1 It is a stereoscopic diagram of the antenna electronic downtilt angle adjustment component of the present invention. Figure 2 Schematic diagram of the antenna electronic downtilt angle adjustment component of the present invention. Figure 1 and 2 As shown, the antenna electronic downtilt angle adjustment component of the present invention comprises: a transmission ruler 1, an angle scale 2 and a sliding block 5. Among them, the angle scale 2 passes through a first channel 31 of a first buckle 3 from a first side A. The transmission ruler 1 is arranged in parallel below the angle scale 2, and passes through a second channel 41 of a second buckle 4 from a second side B opposite to the first side A. The two ends of the sliding block 5 are respectively hinged to the first buckle 3 and the second buckle 4 through the cooperation of the connecting rod 15 and the connecting pin 12. The transmission ruler 1, the sliding block 5 and the two connecting rods 15 form a trapezoidal frame together. When the angle scale 2 is pulled, the trapezoidal frame is compressed in a direction perpendicular to the transmission ruler 1, and the sliding block 5 rises and abuts against the transmission ruler 1, so that the transmission ruler 1 is linked with the angle scale 2 and moves in the same direction. The adjustment of the antenna downtilt angle in the present invention can show the coexistence of remote electric adjustment and manual adjustment. No special adjustment tools are required for manual adjustment, and the manual adjustment speed is faster. The surface of the angle scale 2 is provided with an angle scale reading, but it is not limited to this.

[0070] In a preferred embodiment, a center rod 6 is further provided on the upper surface of the sliding block 5, and a first limiting hole 13 at the end of the transmission ruler 1 and a second limiting hole 14 at the end of the angle scale 2 are sequentially sleeved on the center rod 6, the first limiting hole 13 is a round hole, and the second limiting hole 14 is a strip hole extending along the length direction of the angle scale 2, and the strip hole provides a limiting stroke for the angle scale 2. When the angle scale 2 moves to the second side B, the center rod 6 will move in the opposite direction along the strip hole to avoid the action of the angle scale 2 on the center rod 6, but it is not limited thereto.

[0071] In a preferred embodiment, the first channel 31 and the second channel 41 are parallel to each other, and the extension direction of the central rod 6 is perpendicular to the first channel 31 or the second channel 41 , but not limited thereto.

[0072] In a preferred embodiment, a spring 7 is further included, which is sleeved on the central rod 6, and two ends of the spring 7 are elastically supported on the upper surface of the sliding block 5 and the lower surface of the transmission ruler 1 respectively, but the present invention is not limited thereto.

[0073] In a preferred embodiment, a height limiting rod 8 is provided on the upper surface of the sliding block 5. When the trapezoidal frame is compressed, the upper end of the height limiting rod 8 rises with the sliding block 5 and presses against the lower surface of the transmission ruler 1. The height limiting rod 8 cooperates with the second buckle 4 to clamp the transmission ruler 1, but this is not limited to this.

[0074] In a preferred embodiment, the trapezoidal frame has a first state in which it is lifted by the supporting force of the spring 7 and the transmission ruler 1 and the angle scale 2 do not interfere with each other, and a second state in which the angle scale 2 and the transmission ruler 1 move in conjunction with each other while overcoming the downward pressure of the spring 7. The height of the height limiting rod 8 is less than the height of the trapezoidal frame in the first state, and the height of the height limiting rod 8 is equal to the height of the trapezoidal frame in the second state, but is not limited to this.

[0075] In a preferred embodiment, a second limit plug 10 unidirectionally engaged with the first buckle 3 is provided at the end of the angle scale 2 passing through the first channel 31, and the angle scale 2 freely passes through the first channel 31 of the first buckle 3 toward the second side B, and only moves toward the first side A.

[0076] In a preferred embodiment, a first limit stopper 9 unidirectionally engaged with the second buckle 4 is provided at the end of the transmission ruler 1 passing through the second channel 41, and the transmission ruler 1 freely passes through the second channel 41 of the second buckle 4 toward the second side B, and only moves toward the first side A. After the first limit stopper 9 abuts against the second buckle 4, the transmission ruler 1 and the second buckle 4 are linked, but not limited to this.

[0077] In a preferred embodiment, a screw rod 11 and a motor are further included, the sliding block 5 is elastically pressed on the screw rod 11, and a thread meshing with the screw rod 11 is provided at the bottom of the sliding block 5, but the present invention is not limited thereto.

[0078] In the present invention, the front end of the transmission ruler 1 is connected to a phase shifter (not shown), and when the moving ruler is displaced, the phase shifter is driven to move. The end of the moving ruler is provided with a through hole and a limit hole, and the end through hole passes through the buckle and is sleeved in the center rod. Angle scale 2: The front end is provided with a through hole and a limit hole, and the front through hole passes through the buckle and is sleeved in the center rod, and is stacked on the moving ruler. Buckle: The middle part of the buckle connected to the moving ruler is provided with a through hole to allow the moving ruler to pass through, and the top of the buckle connected to the angle scale 2 is provided with a through hole to allow the angle scale 2 to pass through. The lower part of the buckle is connected to the sliding block through a movable joint. The limit plug is used for the moving ruler and the angle scale 2 to be used after passing through the buckle to prevent falling off. The combination of the sliding block, the spring, and the center rod is used to connect the bottom of the center rod with the top of the sliding block. The center rod between the sliding block and the moving ruler is sleeved with a spring, and the spring provides downward elastic force to the sliding block. The bottom of the sliding block has a thread. The height limit rod is used to limit the upward movement height of the sliding block. The screw rod is used for the sliding block to be pressed on the screw rod by the spring, and the rotation of the screw rod drives the sliding block to move.

[0079] The present invention enables the base station antenna to have a built-in remote control unit (i.e., a reconfigurable computing unit, RCU for short) to achieve remote electric adjustment and manual adjustment without changing the antenna structure. Manual adjustment can be performed by directly pushing and pulling the antenna scale, which is faster and does not require special adjustment tools. The manual and electric modes can be automatically switched without manual intervention, making it more convenient to use.

[0080] It can be seen that the structure of the antenna electronic downtilt angle adjustment component of the present invention can realize the coexistence of remote electrical adjustment and manual adjustment of the antenna downtilt angle. No special adjustment tools are required for manual adjustment, and the manual adjustment speed is faster.

[0081] Figure 3 The present invention is a flowchart of a method for using the first antenna electronic downtilt angle adjustment component of the present invention. Figure 4 Schematic diagram of the antenna electronic downtilt angle adjustment assembly of the present invention being manually moved toward the first side. Figure 3 and 4 As shown, the present invention also provides a method for using an antenna electronic downtilt angle adjustment component, using the above antenna electronic downtilt angle adjustment component, comprising the following steps:

[0082] S110, when the angle scale 2 moves toward the first side A, driving the first buckle 3 to move toward the first side A, the trapezoidal frame is deformed and compressed, the transmission sliding block 5 overcomes the lifting of the elastic member and presses against the lower surface of the transmission scale 1, and the transmission scale 1 and the angle scale 2 move toward the first side A synchronously.

[0083] S120 , after the angle scale 2 stops moving, the sliding block 5 falls down due to the support force of the elastic member, and the sliding block 5 is separated from the transmission scale 1 .

[0084] When the user manually pulls the angle ruler outward, the first buckle 3 moves backward, so that the sliding block moves up, and the height limit rod hits the transmission ruler, driving the transmission ruler to move. When the required angle is adjusted, the angle ruler is released, and the sliding block returns to its original state under the action of the spring and presses on the screw. This method is suitable for workers to directly pull the angle ruler 2 on site to adjust the electronic downtilt angle of the antenna without the need for any additional tools, which greatly simplifies the process and speeds up the adjustment.

[0085] Figure 5 The present invention is a flowchart of a method for using the second antenna electronic downtilt angle adjustment component of the present invention. Figure 6 Schematic diagram of the antenna electronic downtilt angle adjustment assembly of the present invention being manually moved toward the first side. Figure 5 and 6 As shown, the present invention also provides a method for using an antenna electronic downtilt angle adjustment component, using the above antenna electronic downtilt angle adjustment component, comprising the following steps:

[0086] S210, when the angle scale 2 moves toward the second side B, pushing the second buckle 4 to move toward the second side B, the trapezoidal frame is deformed and compressed, the transmission sliding block 5 overcomes the lifting of the elastic member and presses against the lower surface of the transmission scale 1, and the transmission scale 1 and the angle scale 2 move toward the second side A synchronously.

[0087] S220 , after the angle scale 2 stops moving, the sliding block 5 falls down due to the support force of the elastic member, and the sliding block 5 is separated from the transmission scale 1 .

[0088] When the user manually pushes the angle ruler inward, the second buckle 4 moves forward, so that the sliding block moves up, and the height limit rod hits the transmission ruler, driving the transmission ruler to move. When the required angle is adjusted, the angle ruler is released, and the sliding block returns to its original state under the action of the spring and presses on the screw rod; this method is also applicable to the staff directly pulling the angle ruler 2 on site to adjust the electronic downtilt angle of the antenna, without the need for any additional tools, which greatly simplifies the process and speeds up the adjustment.

[0089] Through the above-mentioned using method of the present invention, no special adjustment tools are needed when the user makes manual adjustment, and the manual adjustment is faster.

[0090] Figure 7 It is a schematic diagram of the antenna electronic downtilt angle adjustment component of the present invention electrically moving toward the first side. Figure 8 The flowchart of the method for using the third antenna electronic downtilt angle adjustment component of the present invention is shown in FIG. Figure 7 and 8 As shown, the present invention also provides a third method for using the antenna electronic downtilt angle adjustment component, which adopts the above antenna electronic downtilt angle adjustment component. Unlike the previous method, the present invention does not require manual intervention, and only requires a motor to drive the screw 11 to rotate, including the following steps:

[0091] S310, the motor drives the screw 11 to rotate;

[0092] S320, the screw 11 drives the sliding block 5 to move along the axial direction of the screw 11, and the axial direction of the screw 11 is parallel to the transmission ruler 1 and the angle ruler 2;

[0093] S330 , the sliding block 5 synchronously drives the transmission ruler 1 and the angle ruler 2 to move along the axial direction of the screw rod 11 .

[0094] During electric adjustment, the RCU motor is connected to the screw rod, and the motor drives the screw rod to rotate. The rotation of the screw rod causes the sliding block to move forward and backward, thereby driving the transmission ruler and the angle scale to move. For example: as the motor drives the screw rod 11 to rotate in the clockwise direction, the sliding block 5 moves to the first side A, and synchronously drives the transmission ruler 1 and the angle scale 2 to move to the first side A. Conversely, as the motor drives the screw rod 11 to rotate in the counterclockwise direction, the sliding block 5 moves to the second side B, and synchronously drives the transmission ruler 1 and the angle scale 2 to move to the second side B.

[0095] In summary, the purpose of the present invention is to provide an antenna electronic downtilt angle adjustment component and an adjustment method thereof, which can achieve the coexistence of remote electrical adjustment and manual adjustment of the antenna downtilt angle, and manual adjustment does not require special adjustment tools and is faster.

[0096] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
