Description

Technical Field

[0001] This invention relates to the field of antenna and radar technology, specifically to an antenna and radar module with a rotating support bracket. Background Technology

[0002] Parabolic antenna radar is a highly efficient signal transmission and reception system. Its core structure mainly consists of a parabolic antenna, transmitter, receiver, signal processing unit, and display system. The parabolic antenna is designed to focus and directionally transmit electromagnetic waves from the feed, achieving high gain and good directivity. The transmitter generates and modulates high-frequency signals, which are then transmitted to the antenna via the feed. When the signal encounters a target object during propagation, it is reflected. The returned signal is received by the parabolic antenna and transmitted to the receiver. The receiver amplifies and demodulates these weak reflected signals to ensure the extraction of useful information. The received signal is then sent to the signal processing unit. After algorithmic processing, the system can extract key information such as the target's distance, speed, and direction. Finally, the processing results are presented to the operator in a visual manner through the display system, helping them quickly understand the target situation and make appropriate decisions. To achieve scanning of a wide airspace and tracking of specific targets, the entire reflector and feed assembly are mounted on an antenna mount and driven by a servo drive system, allowing it to rotate flexibly in both azimuth and elevation dimensions. For example, an adjustment bracket for reconnaissance radar disclosed in patent announcement CN222126960U includes a radar antenna body, which is mounted on an elevation adjustment base via fixing bolts. The lower end of the elevation adjustment base is mounted on a rotating adjustment base, which includes a base support housing. A rotation drive device is located at the upper end of the base support housing, and an antenna controller is located within the base support housing. The base support housing includes a cylindrical support housing, and an equipment mounting base is located within the cylindrical support housing. It can be seen that the azimuth and elevation angles of the antenna radar are controlled by a rotation drive motor and an elevation drive motor, respectively. This requires the motor controller to have a corresponding algorithm program set up to achieve the desired elevation angle. The forward and reverse rotation frequency of the elevation drive motor can be synchronized with the azimuth rotation speed of the antenna radar. However, when the antenna performs azimuth rotation and elevation movement simultaneously, especially during high-speed or large-angle maneuvers, the huge reflector and its supporting structure will generate significant inertial forces and torques. These dynamic loads will be transmitted and affect each other between the two motion axis systems. Specifically, the rapid movement of the elevation axis will change the position of the entire antenna's center of gravity, thereby generating a time-varying disturbance torque on the drive load of the azimuth axis, and vice versa. Although the controller can synchronize or coordinate the two motors through algorithms, the algorithms are based on simplified linear models and cannot fully compensate for complex, nonlinear dynamic coupling effects. This will lead to tracking errors, which manifest as a slight lag between the actual pointing and commanded pointing of the antenna. In other words, although the azimuth and elevation dual-motor drive setup of the parabolic antenna radar has a simple structure, it brings deeper problems such as complex control coupling and limited dynamic performance during operation. Summary of the Invention

[0003] The purpose of this invention is to provide an antenna radar module with a rotating support bracket. The rotary actuator in the dual-cylinder housing drives two turntables and their respective elevation movable brackets and parabolic antenna radars to rotate in azimuth. During this process, the follower gear shaft mounted at the bottom of the turntable meshes with the fixed gear ring, so the follower gear shaft keeps rotating, and the rotation speed is proportional to the azimuth rotation speed of the parabolic antenna radar. In turn, the follower gear shaft transmits power to the pitch rocking structure of the axial linkage, and enables the elevation movable bracket and parabolic antenna radar to make regular adjustments to the pitch angle, thereby maintaining flexible and coordinated rotation in both azimuth and pitch dimensions, so as to solve the problem of complex dual-motor control coupling mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an antenna radar module with a rotating support bracket, comprising a double-cylinder housing, a protective plate fixedly installed at the opening at the top of the double-cylinder housing, a turntable rotatably installed on the left and right sides of the top of the protective plate, and a parabolic antenna radar disposed above the turntable. An elevation-angle movable bracket is provided between the bottom end of the parabolic antenna radar and the top end of the turntable. A rotary driver for driving the two turntables to rotate synchronously is installed inside the double-cylinder housing. A fixed gear ring is fixed at the top of the double-cylinder housing below the protective plate, maintaining a coaxial state with the turntable. A follower gear shaft is rotatably installed at one edge of the bottom end of the turntable. The follower gear shaft meshes with the fixed gear ring, and the upper end of the follower gear shaft extends to the outside of the turntable and is equipped with a linkage pitch and rocking structure for driving the elevation-angle movable bracket to move.

[0005] Preferably, a shell edge is fixed at the top edge of the double-cylinder shell, and the inner wall of the shell edge is fixedly connected to the outer wall edge of the protective plate.

[0006] Preferably, a hollow ring is fixed to the top of the double-cylinder shell below the turntable, and a fixed gear ring is fixed coaxially on the outer circumferential wall of the hollow ring. An annular groove for the rotating gear shaft to revolve is provided between the protective plate and the hollow ring.

[0007] Preferably, both sides of the top of the protective plate are fixed with annular bosses, the annular bosses are coaxial with the hollow ring, and the top edge of the annular bosses slides in contact with the lower surface of the turntable.

[0008] Preferably, the rotary drive includes a bevel gear reversing drive mounted on the left and right sides inside the double-cylinder housing, a vertical shaft rotatably mounted at the vertical axis position inside the bevel gear reversing drive, and a servo motor mounted on one side inside the double-cylinder housing. The upper end of the output shaft of the servo motor is fixedly connected to the lower end of one of the vertical shafts by a coupling, and the upper end of the vertical shaft is fixedly connected to the bottom end of the turntable.

[0009] Preferably, the bevel gear reversing drive consists of a double-conical disc housing, a bevel gear drive shaft, and a driving bevel gear. The double-conical disc housing is fixed to one side inside the double-cylinder housing. The bevel gear drive shaft is rotatably mounted inside the double-conical disc housing along the horizontal direction via ball bearings. The vertical shaft is rotatably mounted inside the double-conical disc housing along the vertical axis via roller bearings. The driving bevel gear is fixed on the vertical shaft, and the driving bevel gear and the bevel gear drive shaft are in a meshing state. The opposite ends of the two bevel gear drive shafts on the left and right sides are fixedly connected.

[0010] Preferably, the linkage pitching and rocking structure includes a horizontal shaft and a bevel gear shaft rotatably mounted on the top of the turntable via bearings, and a sprocket drive pair between the horizontal shaft and the bevel gear shaft for maintaining power transmission. A reversing bevel gear for meshing with the bevel gear shaft is fixed at the upper end of the rotating gear shaft, and a linkage structure is provided at both ends of the horizontal shaft.

[0011] Preferably, the linkage structure includes a rotary table fixed to the end of the horizontal shaft, a fisheye connecting rod hinged at the edge of the outer wall of the rotary table, and L-shaped rocker blocks arranged on both sides of the movable support at the elevation angle. The upper end of the L-shaped rocker block is provided with a notch, and the upper end of the fisheye connecting rod is located in the notch and connected to the L-shaped rocker block through a hinge shaft.

[0012] Preferably, the elevation-angle movable support includes a mountain-shaped base frame arranged parallel to the horizontal axis and fixed to the top of the turntable, a pin shaft rotatably installed at the lower position inside the mountain-shaped base frame, and double-layer end arms fixed at both ends of the pin shaft surface. Inwardly folded support arms are installed on the opposite outer walls of the two double-layer end arms. The parabolic antenna radar is installed at the upper end of the two inwardly folded support arms, and the L-shaped rocker block is fixed to the end of the pin shaft.

[0013] Preferably, the surface of the pin is further fixed with a diagonal arm, the upper end of which is connected to one end of the inwardly folded support arm.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The antenna radar module with rotating support bracket is equipped with a structure that includes a double-cylinder shell, a hollow ring, a fixed gear ring, two turntables, an elevation movable bracket, a parabolic antenna radar, a follower gear shaft, and a linkage pitch and rocking structure. It uses a rotary driver as the sole power source. By utilizing the mechanical meshing relationship between the follower gear shaft and the fixed gear ring at the bottom of the turntable, the angular velocity of the parabolic antenna radar's azimuth rotation is directly and instantly converted into a mechanical input that is strictly proportional to the azimuth rotation speed. Through the subsequent linkage pitch and rocking structure, this input is converted into a regular adjustment of the pitch angle. This makes the pitch motion of the parabolic antenna radar no longer dependent on the results of electronic calculation and servo response, but rather the direct mechanical derivative of the azimuth motion. Thus, when performing uniform scanning or tracking targets with specific regular trajectories, it avoids the risks of lag, oscillation, or loss of synchronization that may be caused by software algorithm synchronization in previous dual-motor systems. Secondly, the module has only one rotary actuator as the active power source. The hollow ring sleeve, fixed gear ring, follow-rotating gear shaft, and connecting rod pitch and rocking structure are well-designed with clear failure modes. With good lubrication and protection, it can withstand harsh environments and has an extremely long service life. Moreover, the orientation and pitch rotation accuracy of the module are fixed in the dimensions of the tooth profile and connecting rod pitch and rocking structure during the manufacturing and assembly stages. Once the calibration is completed, its long-term stability is less affected by external electronic environment interference, reducing the need for frequent calibration. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1 to 6 The present invention includes a double-cylinder shell 1, a protective plate 4 fixedly installed at the opening at the top of the double-cylinder shell 1, a turntable 5 rotatably installed on the left and right sides of the top of the protective plate 4, and a parabolic antenna radar 7 set above the turntable 5. An elevation angle movable bracket 6 is provided between the bottom end of the parabolic antenna radar 7 and the top end of the turntable 5. A rotary driver 8 for driving the two turntables 5 to rotate synchronously is installed inside the double-cylinder shell 1. A fixed gear ring 10 is fixed at the top of the double-cylinder shell 1 below the protective plate 4 and is coaxial with the turntable 5. A follower gear shaft 11 is rotatably installed at one edge of the bottom end of the turntable 5. The follower gear shaft 11 meshes with the fixed gear ring 10, and the upper end of the follower gear shaft 11 extends to the outside of the turntable 5 and is equipped with a linkage pitch and rocking structure 9 for driving the elevation angle movable bracket 6 to move. A shell edge 3 is fixed at the top edge of the double-cylinder shell 1. The inner wall of the shell edge 3 is fixed to the outer wall edge of the protective plate 4. A hollow ring sleeve 2 is fixed at the top of the double-cylinder shell 1 below the turntable 5. The fixed gear ring 10 is fixed coaxially on the outer circumferential wall of the hollow ring sleeve 2. An annular groove 401 is provided between the protective plate 4 and the hollow ring sleeve 2 for the rotating gear shaft 11 to revolve. Since the annular groove 401 is provided between the inner side of the protective plate 4 and the outer side of the hollow ring sleeve 2, the rotating gear shaft 11 can use the annular groove 401 as a trajectory line to revolve around the vertical axis of the turntable 5, ensuring that the subsequent components receive power input. The double-cylinder housing 1 provides robust integrated protection and support for the rotary drive 8, hollow ring sleeve 2, and fixed gear ring 10, thereby encapsulating key components and effectively shielding them from direct damage from external environments such as wind, sand, rain, and salt spray. At the same time, it creates a relatively clean and stable working environment for the precise meshing and transmission inside the rotary drive 8. Both sides of the top of the protective plate 4 are fixed with annular bosses 402. The annular bosses 402 are coaxial with the hollow ring 2, and the top edge of the annular bosses 402 slides in contact with the lower surface of the turntable 5. The annular bosses 402 are used to seal the gap between the lower surface of the turntable 5 and the protective plate 4, so as to enable the rotating gear shaft 11 and the fixed gear ring 10 to work in a relatively closed environment. In order to ensure that the linkage pitch and rocking structure 9 is not affected by the external environment, the operator can also set a cover structure on the upper surface of the turntable 5 to protect the linkage pitch and rocking structure 9 without affecting the pitch adjustment of the elevation angle movable bracket 6 and the parabolic antenna radar 7.

[0019] Example 2, based on Example 1, is... Figure 7 , Figure 8 and Figure 9 The rotary drive 8 includes a bevel gear reversing drive 801 mounted on the left and right sides inside the double-cylinder housing 1, a vertical shaft 803 rotatably mounted at the vertical axis position inside the bevel gear reversing drive 801, and a servo motor 802 mounted on one side inside the double-cylinder housing 1. The upper end of the output shaft of the servo motor 802 is fixedly connected to the lower end of one of the vertical shafts 803 by a coupling. The upper end of the vertical shaft 803 is fixedly connected to the bottom end of the turntable 5. The bevel gear reversing drive 801 consists of a double-conical disc housing 8011, a bevel gear drive shaft 8012, and a drive bevel gear 8013. The double-conical disc housing 8011 is fixed to one side inside the double-cylinder housing 1. The bevel gear drive shaft 8012 is rotatably mounted inside the double-conical disc housing 8011 in the horizontal direction via ball bearings. The vertical shaft 803 is rotatably mounted inside the double-conical disc housing 8011 in the vertical axis via roller bearings. The drive bevel gear 8013 is fixed on the vertical shaft 803, and the drive bevel gear 8013 and the bevel gear drive shaft 8012 are in a meshing state. The two bevel gear drive shafts 8012 on the left and right sides are fixedly connected at opposite ends. When the rotary driver 8 is working, the servo motor 802 outputs precise speed and torque to one of the bevel gear reversing drives 801 according to the control command. Then, the two bevel gear reversing drives 801 together output rotational power to the turntable 5 above them via the vertical shaft 803. The output shaft of the servo motor 802 is fixed to the vertical shaft 803 in one of the double-conical disc housings 8011. The vertical shaft 803 directly drives the turntable 5 to rotate. At this time, the vertical shaft 803 drives the bevel gear transmission shaft 8012 to rotate through the active bevel gear 8013. The bevel gear transmission shaft 8012 outputs rotational power to the other bevel gear reversing transmission 801. At this time, both turntables 5 maintain synchronous rotation, thereby performing the azimuth rotation of the elevation angle movable support 6 and the parabolic antenna radar 7. Because there are two parabolic antenna radars 7, one of which can operate at a longer wavelength for wide-area search and early warning, while the other antenna operates at a shorter wavelength for fine tracking and identification of the same area; or one uses a low pulse repetition frequency for ranging and the other uses a high pulse repetition frequency for velocity measurement. The two are mechanically synchronized in terms of azimuth spatial coverage, and can achieve frequency domain or functional complementarity under time synchronization in terms of information acquisition.

[0020] Example 3, based on Example 2, by Figure 10 , Figure 11 and Figure 12The connecting rod pitch and rocking structure 9 includes a horizontal shaft 901 and a bevel gear shaft 902 rotatably mounted on the top of the turntable 5 via bearings, and a sprocket drive pair 904 between the horizontal shaft 901 and the bevel gear shaft 902 for maintaining power transmission. The upper end of the rotating gear shaft 11 is fixed with a reversing bevel gear 903 for meshing with the bevel gear shaft 902. Both ends of the horizontal shaft 901 are provided with connecting rod structures. The connecting rod structures include a rotary disk 905 fixed on the end of the horizontal shaft 901, a fisheye connecting rod 906 hinged at the outer edge of the rotary disk 905, and L-shaped rocker blocks 907 provided on both sides of the pitch angle movable bracket 6. The upper end of the L-shaped rocker block 907 is provided with a notch 9071. The upper end of the fisheye connecting rod 906 is located in the notch 9071 and is connected to the L-shaped rocker block 907 via a hinge shaft. During the revolution of the follower gear shaft 11 around the fixed gear ring 10, the upper end of the follower gear shaft 11 will drive the bevel gear shaft 902 to rotate through the reversing bevel gear 903, and then drive the horizontal shaft 901 to rotate through the sprocket transmission pair 904. At this time, the rotary table 905 will rotate along with the horizontal shaft 901. Since the ends of the fisheye connecting rod 906 are located at the edge of the rotary table 905 and the upper end of the L-shaped rocker block 907 respectively, the continuous rotation of the rotary table 905 is converted into the swinging action of the L-shaped rocker block 907 within a certain angle range through the fisheye connecting rod 906. That is, the pitch adjustment power of the pitch-adjustable bracket 6 is obtained. The elevation-angle movable support 6 includes a mountain-shaped base frame 601 that is parallel to the horizontal shaft 901 and fixed to the top of the turntable 5, a pin 602 that is rotatably installed at the lower position inside the mountain-shaped base frame 601, and double-layer end arms 603 that are fixed at both ends of the surface of the pin 602. Inwardly folded support arms 604 are installed on the opposite outer walls of the two double-layer end arms 603. The parabolic antenna radar 7 is installed on the upper end of the two inwardly folded support arms 604. The L-shaped rocker block 907 is fixed to the end of the pin 602. A diagonal arm 605 is also fixed to the surface of the pin 602. The upper end of the diagonal arm 605 is connected to one end of the inwardly folded support arm 604. The lower end of the parabolic antenna radar 7 is fixed on the inward-folding support arm 604. The inclined arm 605, the inward-folding support arm 604 and the inward-folding support arm 604 form a frame and can rotate under the drive of the pin 602. That is, when the pin 602 is driven by the turntable 905, the fisheye connecting rod 906 and the L-shaped rocker block 907 to rotate forward and backward, the inclined arm 605, the inward-folding support arm 604 and the double-layer end arm 603 synchronously follow the axis of the pin 602 to perform pitch movement, thereby realizing the pitch freedom of the parabolic antenna radar 7.

[0021] In this embodiment, when the radar system needs to execute scanning or tracking commands, the rotary driver 8 is activated. Its power output shaft directly drives the turntable 5 at the top of the protective plate 4 to rotate, directly causing the rigidly connected elevation movable bracket 6 and the parabolic antenna radar 7 mounted on the elevation movable bracket 6 to rotate around the vertical axis of the turntable 5 in azimuth. This allows the beam pointing of the parabolic antenna radar 7 to achieve complete 360-degree coverage on the horizontal plane. During this process, the entire rotary driver 8 is encapsulated in a double-cylinder housing 1, which provides necessary protection and support. At the same time, the internal cavity design ensures that the transmission components have sufficient operating space. While the entire upper structure rotates in azimuth, the follower gear shaft 11, which is rotatably mounted at the bottom of the turntable 5, is engaged with the fixed gear ring 10 fixed on the outside of the hollow ring sleeve 2. Therefore, when the turntable 5 carries the follower gear shaft 11 in azimuth rotation, the meshing relationship between the fixed gear ring 10 and the follower gear shaft 11 forces the follower gear shaft 11 to rotate. While revolving around the sun, the rotating gear shaft 11 also rotates on its own axis. The angular velocity of the rotation of the rotating gear shaft 11 is directly proportional to the angular velocity of the azimuth rotation, i.e., the rotational speed of the turntable. This ratio is determined by the ratio of the number of teeth between the fixed gear ring 10 and the rotating gear shaft 11. In other words, the faster the azimuth rotation of the parabolic antenna radar 7, the faster the rotation of the rotating gear shaft 11. The linkage pitch and rocking structure 9 receives the rotational power from the rotating gear shaft 11 and converts it into the reciprocating oscillation of the elevation movable support 6 within a certain angle range. Therefore, as the azimuth rotation continues, the rotating gear shaft 11 rotates faster. The gear shaft 11 rotates continuously, driving the elevation angle movable bracket 6 and the parabolic antenna radar 7 on it to periodically change their elevation angle around the horizontal axis through the pushing and pulling action of the linkage pitch rocking structure 9. When the parabolic antenna radar 7 is working, from the issuance of the command to the presentation of the information, the signal goes through a complete closed loop: generated by the transmitter, radiated by the feed source through the duplexer and waveguide, shaped into a beam by the reflector, scattered by the target after propagation in space, collected by the reflector and converged to the feedback source, and finally detected and processed through the receiving chain.
