Description

Technical Field

[0001] This utility model relates to the field of communication antenna technology, and more specifically, to a pitch rotation mechanism for a scattering communication antenna. Background Technology

[0002] Scatter communication is a method of long-distance communication that utilizes the scattering effect of electromagnetic waves by the troposphere and ionosphere. In scatter communication systems, the adjustment of the antenna's elevation angle is crucial, as it directly affects the signal reception and transmission performance.

[0003] Existing systems allow for a large range of adjustment for the elevation angle of communication radars, resulting in a large space requirement and footprint for these radars.

[0004] A search revealed that Chinese Patent CN218409355U discloses a pitch and rotation mechanism for a communication radar. This structure uses a central rod, mounting bracket, and electric push rod to adjust the height of the communication radar body, improving installation stability. Solar panels and batteries power the communication radar body and the adjustment motor, reducing the impact and interference of obstacles on the communication radar body and facilitating autonomous power supply. Furthermore, the adjustment motor, first worm gear, second worm wheel, and support plate enable the drive motor to drive the communication radar body to rotate and tilt via the first and second worm gears respectively, shortening the tilt angle movement space and reducing the space occupied.

[0005] However, in actual use, the adjustment system consisting of the central rod, mounting bracket, and electric push rod is an indirect transmission. The linear extension and retraction motion of the electric push rod needs to be converted into the pitch rotation of the communication antenna body through the mounting bracket. This conversion of motion forms will amplify the error. In addition, the electric push rod itself has a return gap. During repeated adjustments, the mechanical gap will continue to accumulate, causing the angle control accuracy to decrease further, making it difficult to accurately control the pitch angle. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pitch rotation mechanism for a scattering communication antenna to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pitch rotation mechanism for a scattering communication antenna includes a support base, a U-shaped frame fixedly mounted on the top of the support base, a fixed plate rotatably mounted on one side of the U-shaped frame, a communication antenna mounted on one side of the fixed plate, and a pitch rotation mechanism mounted on the top of the support base.

[0009] The pitch and rotation mechanism includes a stepper motor fixedly mounted on the top of the support base. A main rotating rod is fixedly installed at the output end of the stepper motor. A first gear ring is fixedly installed on the surface of the main rotating rod. A second gear ring meshes with the surface of the first gear ring. A driven rotating rod is fixedly installed inside the second gear ring. One end of the driven rotating rod passes through the U-shaped frame and is fixedly connected to the fixed plate. An auxiliary plate is rotatably installed at one end of both the main rotating rod and the driven rotating rod.

[0010] A mounting base is fixedly provided on the top of the fixing plate, the communication antenna is installed on the top of the mounting base, a support bar is fixedly provided on one end of the communication antenna, and one end of the support bar is connected to the fixing plate.

[0011] By adopting the above technical solutions, the pitch angle of the communication antenna can be precisely adjusted; the auxiliary plate ensures the stability of the rotation of the main rotating rod and the driven rotating rod; and the mounting base and support bar enhance the firmness of the communication antenna installation, thereby improving the overall reliability and accuracy of the mechanism operation.

[0013] One end of the transmission rod is rotatably provided with a connecting bar, one end of the connecting bar is fixedly provided with a fixing rod, and one end of the fixing rod is rotatably provided with a support leg.

[0014] By adopting the above technical solution, the mechanism can adaptively adjust with the rotation of the fixed plate, enhance the overall support stability of the mechanism through the support legs, effectively disperse the force generated when the communication antenna rotates, and improve the smoothness of the mechanism's operation and structural strength.

[0015] As a further description of the above technical solution: a bearing is provided at the connection between the rotating rod and the U-shaped frame, the outer ring of the bearing is fixedly connected to the U-shaped frame and the inner ring is fixedly connected to the rotating rod, a protective shell is provided on the outside of the stepper motor, the first gear ring and the second gear ring, the protective shell is fixedly installed on the top of the support base, and multiple heat dissipation holes are opened on the surface of the protective shell, and a dustproof mesh is provided inside the heat dissipation holes.

[0016] By adopting the above technical solutions: the bearing configuration reduces the friction between the rotating rod and the U-shaped frame, ensuring smooth rotation of the rotating rod, reducing energy consumption and wear, and the dustproof net blocks dust, improving the operational stability and service life of the components, and ensuring reliable operation of the mechanism.

[0017] The technical effects and advantages of this utility model are as follows:

The characteristics of the stepper motor ensure high angle adjustment accuracy, meeting the strict requirements of scatter communication for directivity. Moreover, the auxiliary plates at one end of the main rotating rod and the driven rotating rod provide stable support, reduce shaking during rotation, and enhance the overall rigidity of the mechanism. The bearing at the connection between the driven rotating rod and the U-shaped frame reduces frictional resistance, making the rotation smoother, reducing energy loss, and extending the service life of the components. The coordinated work of all components improves the reliability and stability of the pitch adjustment of the communication antenna.

[0019] 2. By incorporating auxiliary mechanisms, compared to existing technologies, the stability of the communication antenna installation is enhanced through the mounting base and support bars, preventing the antenna from loosening during rotation or use. Furthermore, the hinged design of the connecting plate and fixing plate, combined with the rotational connection of the transmission rod, connecting bars, fixing rod, and support legs, automatically adjusts to changes in the communication antenna's pitch angle, ensuring the support legs always provide effective support and significantly improving the overall stability of the mechanism. In addition, the protective shell protects core components such as the stepper motor from external impacts, heat dissipation holes aid internal heat dissipation to prevent component failure due to high temperatures, and a dustproof mesh prevents dust from entering, ensuring smooth operation of the transmission components, extending the mechanism's service life, and improving operational reliability.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The pitch rotation mechanism of the scattering communication antenna shown includes a support base 1, a U-shaped frame 2 fixedly installed on the top of the support base 1, a fixed plate 3 rotatably installed on one side of the U-shaped frame 2, a communication antenna 4 installed on one side of the fixed plate 3, and a pitch rotation mechanism installed on the top of the support base 1.

[0028] The pitch rotation mechanism includes a stepper motor 5 fixedly installed on the top of the support base 1. A main rotating rod 6 is fixedly installed at the output end of the stepper motor 5. A first gear ring 7 is fixedly installed on the surface of the main rotating rod 6. A second gear ring 8 meshes with the surface of the first gear ring 7. A driven rotating rod 9 is fixedly installed inside the second gear ring 8. One end of the driven rotating rod 9 passes through the U-shaped frame 2 and is fixedly connected to the fixed plate 3. An auxiliary plate 10 is rotatably installed at one end of both the main rotating rod 6 and the driven rotating rod 9.

[0029] A mounting base 11 is fixedly installed on the top of the mounting plate 3. The communication antenna 4 is installed on the top of the mounting base 11. A support bar 12 is fixedly installed on one end of the communication antenna 4. One end of the support bar 12 is connected to the mounting plate 3.

[0030] When it is necessary to adjust the pitch angle of the communication antenna 4, the stepper motor 5, which is fixedly installed on the top of the support base 1, is started first. After the stepper motor 5 starts working, its output end will drive the main rotating rod 6 to rotate. During the rotation of the main rotating rod 6, the first gear ring 7, which is fixedly set on its surface, will rotate together.

[0031] Since the first gear ring 7 meshes with the second gear ring 8, the rotation of the first gear ring 7 will drive the second gear ring 8 to rotate accordingly. The second gear ring 8 has a fixed rotating rod 9 inside, so the rotation of the second gear ring 8 will drive the rotating rod 9 to rotate.

[0032] The U-shaped frame 2 is passed through one end of the rotating rod 9 and fixedly connected to the fixing plate 3. Therefore, the rotation of the rotating rod 9 will directly drive the fixing plate 3 to rotate around the rotating rod 9 as the axis, thereby realizing the adjustment of the elevation angle of the communication antenna 4 set on one side of the fixing plate 3.

[0033] Reference Figure 2-3 As shown, an auxiliary mechanism is provided on one side of the fixed plate 3. The auxiliary mechanism includes a connecting plate 13 hinged to one side of the fixed plate 3, and transmission rods 14 are rotatably provided on both sides of the connecting plate 13.

[0034] A connecting bar 15 is rotatably provided at one end of the transmission rod 14, a fixing rod 16 is fixedly provided at one end of the connecting bar 15, and a support leg 17 is rotatably provided at one end of the fixing rod 16.

[0035] In addition, the mounting base 11 fixedly installed on the top of the fixing plate 3 is used to install the communication antenna 4. The support bar 12 at one end of the communication antenna 4 is connected to the fixing plate 3, which enhances the stability of the installation of the communication antenna 4.

[0036] When the communication antenna 4 is tilted, the fixed plate 3 rotates around the rotating rod 9. The fixed plate 3 will drive the connecting plate 13, which is hinged to it, to move synchronously. Since the connecting plate 13 and the fixed plate 3 are hinged, the connecting plate 13 can rotate flexibly around the hinge point to adapt to the angle offset of the fixed plate 3.

[0037] Meanwhile, the transmission rods 14, which are rotatably arranged on both sides of the connecting plate 13, will change their angle as the position of the connecting plate 13 changes. One end of the transmission rod 14 is rotatably connected to the connecting strip 15. This rotational relationship allows the transmission rod 14 to drive the connecting strip 15 to adjust its displacement and angle.

[0038] Furthermore, the fixing rod 16 fixed at one end of the connecting bar 15 will move with the movement of the connecting bar 15. The rotational connection between the fixing rod 16 and the support leg 17 allows the support leg 17 to adjust its own support angle according to the position change of the fixing rod 16, further assisting in ensuring the stable operation of the entire mechanism.

[0039] Reference Figure 4-5 As shown, a bearing 18 is provided at the connection between the rotating rod 9 and the U-shaped frame 2. The outer ring of the bearing 18 is fixedly connected to the U-shaped frame 2 and the inner ring is fixedly connected to the rotating rod 9. A protective shell 19 is provided on the outside of the stepper motor 5, the first gear ring 7 and the second gear ring 8. The protective shell 19 is fixedly installed on the top of the support base 1. Multiple heat dissipation holes are opened on the surface of the protective shell 19, and a dustproof mesh 20 is provided inside the heat dissipation holes.

[0040] Throughout the rotation process, auxiliary plates 10 are rotatably mounted at one end of both the main rotating rod 6 and the driven rotating rod 9. The auxiliary plates 10 serve to assist in supporting and stabilizing the rotation of the main rotating rod 6 and the driven rotating rod 9. At the same time, the bearing 18 installed at the connection between the driven rotating rod 9 and the U-shaped frame 2 can reduce the friction when the driven rotating rod 9 rotates, ensuring smooth rotation. Moreover, the protective shell 19 outside the stepper motor 5, the first gear ring 7, and the second gear ring 8 serves to protect the internal components. The heat dissipation holes on the surface of the protective shell 19 help dissipate heat from the internal components, and the dustproof mesh 20 inside the heat dissipation holes can prevent dust from entering and affecting the normal operation of the components.

[0041] Working principle of this utility model:

[0042] This utility model is a pitch rotation mechanism for a scattering communication antenna. When the pitch angle of the communication antenna 4 needs to be adjusted during use, the stepper motor 5, which is fixedly installed on the top of the support base 1, is started first. After the stepper motor 5 starts working, its output end will drive the main rotating rod 6 to rotate. During the rotation of the main rotating rod 6, the first gear ring 7, which is fixedly set on its surface, will rotate together.

[0043] Since the first gear ring 7 meshes with the second gear ring 8, the rotation of the first gear ring 7 will drive the second gear ring 8 to rotate accordingly. The second gear ring 8 has a fixed rotating rod 9 inside, so the rotation of the second gear ring 8 will drive the rotating rod 9 to rotate.

[0044] The U-shaped frame 2 is passed through one end of the rotating rod 9 and fixedly connected to the fixing plate 3. Therefore, the rotation of the rotating rod 9 will directly drive the fixing plate 3 to rotate around the rotating rod 9 as the axis, thereby realizing the adjustment of the elevation angle of the communication antenna 4 set on one side of the fixing plate 3.

[0045] During the entire rotation process, auxiliary plates 10 are rotatably installed at one end of both the main rotating rod 6 and the driven rotating rod 9. The auxiliary plates 10 serve to assist in supporting and stabilizing the rotation of the main rotating rod 6 and the driven rotating rod 9. At the same time, the bearing 18 installed at the connection between the driven rotating rod 9 and the U-shaped frame 2 can reduce the friction when the driven rotating rod 9 rotates, ensuring smooth rotation.

[0046] In addition, the mounting base 11 fixedly installed on the top of the fixing plate 3 is used to install the communication antenna 4. The support bar 12 at one end of the communication antenna 4 is connected to the fixing plate 3, which enhances the stability of the installation of the communication antenna 4.

[0047] When the communication antenna 4 is tilted, the fixed plate 3 rotates around the rotating rod 9. The fixed plate 3 will drive the connecting plate 13, which is hinged to it, to move synchronously. Since the connecting plate 13 and the fixed plate 3 are hinged, the connecting plate 13 can rotate flexibly around the hinge point to adapt to the angle offset of the fixed plate 3.

[0048] Meanwhile, the transmission rods 14, which are rotatably arranged on both sides of the connecting plate 13, will change their angle as the position of the connecting plate 13 changes. One end of the transmission rod 14 is rotatably connected to the connecting strip 15. This rotational relationship allows the transmission rod 14 to drive the connecting strip 15 to adjust its displacement and angle.

[0049] Furthermore, the fixing rod 16 fixed at one end of the connecting bar 15 will move with the movement of the connecting bar 15. The rotational connection between the fixing rod 16 and the support leg 17 allows the support leg 17 to adjust its own support angle according to the position change of the fixing rod 16, further assisting in ensuring the stable operation of the entire mechanism.

[0050] Furthermore, the protective shell 19 outside the stepper motor 5, the first gear ring 7, and the second gear ring 8 serves to protect the internal components. The heat dissipation holes on the surface of the protective shell 19 help dissipate heat from the internal components, while the dustproof mesh 20 inside the heat dissipation holes prevents dust from entering and affecting the normal operation of the components.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
