Description

Technical Field

[0001] This application belongs to the field of airborne radar technology, and more specifically, relates to an airborne servo turntable. Background Technology

[0002] Existing airborne servo turntables are devices specifically designed for aircraft, providing precise azimuth and pitch control for mounting and operating various sensors, cameras, radars, and other equipment. These turntables are miniaturized, with limited space and complex electromagnetic environments for their onboard systems.

[0003] The existing Chinese utility model patent with publication number CN216850289U discloses a turntable device that can reduce the weight and size of the turntable device and make it more compact. However, the internal space is small and there are many cables, which makes it impossible to achieve synchronous rotation of the detection equipment and the control system. The cables often become tangled and break, leading to dangerous situations such as electric shock and fire. Therefore, there is a need to provide an airborne servo turntable to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide an airborne servo turntable to solve the technical problem in the prior art where small turntables have limited internal space and numerous lines, making it impossible to achieve synchronous rotation of the detection equipment and control system, which leads to tangled and broken lines and dangerous situations.

[0005] To achieve the above objectives, this application provides an airborne servo turntable, including a turntable housing and a rotating sleeve. The rotating sleeve is rotatably disposed within the turntable housing. A first rotating mounting platform and a second rotating mounting platform are fixedly connected to both ends of the rotating sleeve. A drive motor capable of driving the second rotating mounting platform to rotate is sleeved inside the second rotating mounting platform. The first rotating mounting platform is used to install detection equipment, and the second rotating mounting platform is used to install control equipment.

[0006] Preferably, a guide gear is fixedly connected to the bottom of the turntable housing, the guide gear is sleeved on the outer edge of the rotating sleeve, and the output end of the drive motor is provided with an output gear, which meshes with the guide gear.

[0007] Preferably, a manifold ring is fixedly sleeved on the outer side of the rotating sleeve.

[0008] Preferably, the second rotary mounting platform extends outward to have a protective platform, and the guide gear is located inside the protective platform.

[0009] Preferably, the rotating sleeve has a through hole near the top of the manifold.

[0010] Preferably, a washer is provided in the lower section of the turntable housing.

[0011] Preferably, the outer side of the rotating sleeve and the inner side of the turntable housing are in contact through a receiving member.

[0012] Preferably, the upper inner side of the turntable housing is provided with a step, and the top of the step contacts the bottom of the first rotary mounting platform through a support member.

[0013] The beneficial effects of this application are as follows: This application provides an airborne servo turntable that uses a drive motor to drive the first rotary mounting platform, the second rotary mounting platform, and the rotating sleeve to rotate synchronously. This ensures that the detection equipment and control system rotate synchronously, preventing cable damage and breakage due to twisting and entanglement during the operation of the rotating sleeve. This effectively prevents the risk of electric shock caused by cable breakage, significantly improving the safety and reliability of equipment operation. Furthermore, the rotating sleeve has sufficient internal space to store more wires, significantly reducing mutual interference and entanglement between wires. In summary, this application has sufficient internal space to store wires, enabling synchronous rotation of the detection equipment and control system, avoiding wire entanglement and breakage, and making it safer and more reliable to use.

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] Please see Figure 1-2An airborne servo turntable, as provided in one embodiment of this application, includes a turntable housing 2 and a rotating sleeve 6. The rotating sleeve 6 is rotatably disposed within the turntable housing 2. A first rotating mounting platform 1 and a second rotating mounting platform 12 are fixedly connected to both ends of the rotating sleeve 6. A drive motor 13, capable of driving the rotation of the second rotating mounting platform 12, is housed inside the second rotating mounting platform 12. The first rotating mounting platform 1 is used to mount detection equipment, and the second rotating mounting platform 12 is used to mount control equipment. The hollow portion of the rotating sleeve 6 is used to house cables. The drive motor 13 drives the second rotating mounting platform 12 to rotate, thereby causing the rotating sleeve 6, fixed to the top of the second rotating mounting platform 12, and the first rotating mounting platform 1 to rotate synchronously. The detection equipment can be an antenna, a camera, etc.; the control equipment can be a control cabinet, a programmable logic controller, etc. The rotating sleeve 6 is used here to achieve synchronous rotation of the detection and control equipment. This not only utilizes its hollow interior to store wiring, making better use of space, but also ensures that the cables inside the detection and control equipment do not twist or become tangled, preventing cable breaks and extending cable lifespan. It also avoids the risk of electric shock due to cable breakage, improving the safety of equipment operation.

[0020] Furthermore, a guide gear 11 is fixedly connected to the bottom of the turntable housing 2. The guide gear 11 is sleeved on the outer edge of the rotating sleeve 6. The output end of the drive motor 13 is provided with an output gear 10, which meshes with the guide gear 11. When the output end of the drive motor 13 rotates, it drives the output gear 10 to rotate together. When the output gear 10 rotates, it rotates along the meshing guide gear 11, driving the second rotating mounting platform 12 to rotate together, so that the rotating sleeve 6 fixed on the top of the second rotating mounting platform 12 and the first rotating mounting platform 1 rotate synchronously. Here, the guide gear 11 is used to guide the output gear 10, causing the output gear 10 to rotate along the guide gear 11, which achieves a good guiding effect.

[0021] Specifically, a busbar ring 5 is fixedly fitted onto the outer side of the rotating sleeve 6. This busbar ring 5 forms a communication loop between the detection device and the control device. Fixing the busbar ring 5 onto the outer side of the rotating sleeve 6 ensures that the busbar ring 5 rotates synchronously with the rotating sleeve 6, guaranteeing the continuity and stability of the communication loop and further improving the reliability of signal transmission. As an optional embodiment, the rotating sleeve 6 and the busbar ring 5 can be fixed by providing mating protrusions 15. These protrusions create a gap between the busbar ring 5 and the rotating sleeve 6, facilitating airflow, carrying away heat generated during rotation, improving heat dissipation performance, preventing overheating, and better protecting the equipment.

[0022] In an optional embodiment, the second rotary mounting platform 12 extends outward with a protective platform 9, and the guide gear 11 is located inside the protective platform 9. Here, the protective platform 9 is used to surround the guide gear 11, which not only prevents the guide gear 11 from being disturbed by external debris, but also prevents the guide gear 11 from falling off when it is running at high speed or under impact, thus ensuring the safe operation of the device.

[0023] Specifically, the rotating sleeve 6 has a through hole 14 near the top of the bus ring 5. The through hole 14 is used to transmit power to the detection device, the bus ring 5 and the control device, which can effectively manage the cable and prevent signal interference caused by cable tangling.

[0024] The lower section of the turntable housing 2 is equipped with a washer 7. The washer 7 supports the manifold ring 5, which not only reduces friction between the manifold ring 5 and the turntable housing 2, reducing wear, but also ensures the stable rotation of the manifold ring 5 and improves rotational stability.

[0025] Furthermore, the outer side of the rotating sleeve 6 and the inner side of the turntable housing 2 are in contact through the receiving member 8. Here, the receiving member 8 is used to support the rotating sleeve 6 and the turntable housing 2, ensuring that the rotating sleeve 6 and the turntable housing 2 do not come into contact, thereby ensuring that the rotating sleeve 6 will not cause wear to the turntable housing 2 during rotation and extending the service life of the equipment.

[0026] Optionally, a step 3 is provided on the inner circumferential side of the upper section of the turntable housing 2, and the top of the step 3 contacts the bottom of the first rotary mounting platform 1 through a support member 4. Here, the step 3 and the support member 4 are used to support the first rotary mounting platform 1, providing stable support for the first rotary mounting platform 1 and ensuring the stable operation of the first rotary mounting platform 1.

[0027] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
