Description

Technical Field

[0001] This utility model relates to the field of antenna technology, specifically to an antenna horn with a feeding system. Background Technology

[0002] In fields such as communications and radar, antenna horns are key components for signal reception and transmission; their angle adjustment accuracy and ease of operation directly affect the system's signal transmission efficiency. Currently, large antenna horns used in the industry generally suffer from several shortcomings:

[0003] 1. Traditional large antenna speakers adopt an integral rigid structure without a compact transmission design, occupy a lot of space, and are difficult to adapt to space-constrained scenarios such as vehicle-mounted and small base stations.

[0004] 2. In terms of adjustment method, it relies on manual rotation of the adjustment rod to adjust the angle, which requires multiple people to operate together.

[0005] 3. In terms of signal adaptation capability, there is no real-time phase detection mechanism. It can only receive single-band signals at a preset fixed angle. In complex communication environments with multiple frequency bands, the signal reception stability is poor and signal interruption is likely to occur.

[0006] These shortcomings mean that traditional antenna horns cannot meet the demands of current complex communication scenarios for spatial adaptability, adjustment efficiency, signal diversity, and equipment security. Therefore, it is urgent to design a new type of antenna horn to solve these problems. Utility Model Content

[0007] The technical problem this invention aims to solve is that traditional antennas and horns are large in size, cumbersome to adjust, have limited signal reception, and poor security.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] This utility model proposes an antenna horn with a feeding system, comprising:

[0010] The antenna horn body is used to receive or transmit signals;

[0011] A drive mechanism is connected to the antenna horn body for driving the antenna horn body to rotate around its axis to adjust the signal receiving angle. The drive mechanism includes a polarized motor, a polarized motor gear and a large gear meshing in sequence. The large gear is fixedly connected to the antenna horn body. The polarized motor drives the polarized motor gear to rotate, which in turn drives the antenna horn body to rotate through the large gear.

[0012] A phase detection mechanism, linked to the drive mechanism, is used to detect the phase angle of the antenna horn body in real time and output a phase detection signal. The phase detection mechanism includes a phase sensor, a sensing transition gear, a sensing pinion, and a sensing gear. A bracket is provided at the bottom of the antenna horn body. The sensing transition gear and the sensing pinion are coaxially rotatably mounted on one side of the bracket via a shaft. The sensing transition gear meshes with a large gear. A resolver seat is provided on the side of the bracket for mounting the phase sensor. A sensing gear that meshes with the sensing pinion is provided on one side of the bracket. The sensing gear is connected to the signal input terminal of the phase sensor.

[0013] Preferably, it also includes a limit protection mechanism, which is located outside the rotation path of the antenna horn body to limit the rotation limit angle of the antenna horn body to protect the equipment.

[0014] The limiting protection mechanism includes at least two limiting brackets and a stop block fixed to the large gear or the antenna horn body. The limiting brackets are spaced apart along the rotation direction of the antenna horn body, and the stop block rotates synchronously with the antenna horn body. When the stop block contacts any limiting bracket, the limiting protection mechanism triggers a stop signal to cut off the power output of the polarization motor.

[0015] Preferably, the phase sensor is a resolver sensor, and the output terminal of the resolver sensor is connected to a signal processing unit. The signal processing unit is used to convert the phase detection signal into identifiable angle data and transmit it to the control terminal.

[0016] Preferably, the limit protection mechanism further includes a limit switch, which is disposed on the limit bracket. When the impact block contacts the limit bracket, the impact block triggers the limit switch, and the limit switch outputs a stop signal to the polarized motor.

[0017] Preferably, the large gear is coaxially fixed with the antenna horn body, and the axis of the large gear coincides with that of the antenna horn body, ensuring that there is no eccentric deviation when the large gear drives the antenna horn body to rotate.

[0018] The antenna horn with a feeding system proposed in this utility model has the following beneficial effects achieved by adopting the above structure:

[0019] 1. Multi-stage gear transmission integrates drive and detection components, reducing the size of the structure and increasing its compactness, making it suitable for vehicle-mounted, small base station and other scenarios.

[0020] 2. In terms of adjustment efficiency, electric adjustment replaces manual operation, shortening adjustment time and reducing labor costs.

[0021] 3. In terms of signal adaptability, real-time phase detection can dynamically adjust the angle according to multiple frequency bands such as 2.4GHz, 5GHz, and 10GHz to meet the needs of complex communication environments.

[0022] 4. In terms of equipment safety, the limit protection mechanism avoids excessive rotation, reduces failure rate and maintenance costs, and extends equipment service life. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0035] Example 1:

[0036] This embodiment focuses on describing the compact design of the drive mechanism 2 to reduce the overall structural size and adapt to space-constrained scenarios such as vehicle-mounted and small base stations.

[0037] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 An antenna horn with a feeding system includes an antenna horn body 1, a drive mechanism 2, a phase detection mechanism 3, and a bracket 4. The drive mechanism 2 is connected to the antenna horn body 1 and drives the antenna horn body 1 to rotate around its axis. The drive mechanism 2 includes a polarization motor 21, a polarization motor gear 22, and a large gear 23. The polarization motor 21 is fixed by a motor base 24. The polarization motor gear 22 is connected to the output shaft of the polarization motor 21 and meshes with the large gear 23. The large gear 23 is coaxially fixed to the antenna horn body 1, and the axis of the large gear 23 coincides with that of the antenna horn body 1 to ensure no eccentric deviation during rotation.

[0038] When the polarization motor 21 starts, it drives the polarization motor gear 22 to rotate, which in turn drives the antenna horn body 1 to rotate via the large gear 23. This multi-stage gear transmission design integrates the drive components into a compact space, significantly reducing the space occupied by the antenna horn and improving the structural compactness.

[0039] Example 2:

[0040] This embodiment focuses on describing the electric adjustment method to replace traditional manual operation, thereby improving adjustment efficiency and convenience.

[0041] Continue to refer to Figures 1 to 3The polarization motor 21 of the drive mechanism 2 receives external control signals (such as instructions from the control terminal) and automatically drives the antenna horn body 1 to rotate. Users can remotely or locally control the operation of the polarization motor 21 via the control terminal without manually operating the adjustment lever. The polarization motor 21 precisely controls the rotation angle of the antenna horn body 1 through gear transmission (polarization motor gear 22 and large gear 23), and the adjustment process is fast and requires no multiple people to coordinate. This greatly shortens the angle adjustment time, reduces labor costs, and is suitable for communication scenarios requiring frequent adjustments.

[0042] Example 3:

[0043] This embodiment focuses on describing the real-time detection function of the phase detection mechanism 3, which enables dynamic adaptation of multi-frequency band signals and improves signal reception stability.

[0044] refer to Figure 3 , Figure 4 and Figure 5 The phase detection mechanism 3 is linked with the drive mechanism 2 and includes a phase sensor 41, a sensing transition gear 42, a sensing pinion 43, a sensing gear 44, a resolver base 45, and a shaft 46. A bracket 4 is provided at the bottom of the antenna horn body 1. The sensing transition gear 42 and the sensing pinion 43 are coaxially rotatably mounted on one side of the bracket 4 via the shaft 46. The sensing transition gear 42 meshes with the large gear 23 and rotates with the large gear 23. A resolver base 45 is provided on the side of the bracket 4 for mounting the phase sensor 41 (preferably a resolver sensor). A sensing gear 44 is provided on one side of the bracket 4, meshing with the sensing pinion 43, and the sensing gear 44 is connected to the signal input terminal of the phase sensor 41. When the antenna horn body 1 rotates, the large gear 23 drives the sensing transition gear 42 to rotate, transmitting the signal to the phase sensor 41 through the sensing pinion 43 and the sensing gear 44. The phase sensor 41 detects the phase angle of the antenna horn body 1 in real time and outputs a phase detection signal. The output of the phase sensor 41 is connected to a signal processing unit (not shown in the figure). The signal processing unit converts the phase detection signal into identifiable angle data (such as digital angle values) and transmits it to the control terminal. The control terminal can dynamically adjust the angle of the antenna horn body 1 according to the needs of multi-band signals (such as 2.4GHz, 5GHz, 10GHz) to ensure the diversity and stability of signal reception in complex communication environments.

[0045] Example 4: An Example for Solving Security Issues

[0046] This embodiment focuses on describing the limit protection mechanism 5, which prevents the antenna horn body 1 from rotating excessively, thereby improving equipment safety and service life.

[0047] refer to Figure 1 , Figure 2 and Figure 4The limit protection mechanism 5 is located outside the rotation path of the antenna horn body 1 and includes at least two limit brackets 51, a stop block 52, and a limit switch 53. The stop block 52 is fixed to the large gear 23 or the antenna horn body 1 and rotates synchronously with the antenna horn body 1. The limit brackets 51 are spaced apart along the rotation direction of the antenna horn body 1. When the stop block 52 contacts any limit bracket 51 during rotation, the stop block 52 triggers the limit switch 53 (located on the limit bracket 51). The limit switch 53 outputs a stop signal to the polarization motor 21, cutting off the power output of the polarization motor 21. This limits the rotation limit angle of the antenna horn body 1, avoids damage to the mechanical structure, reduces the failure rate and maintenance costs, and extends the service life of the equipment.
