The T-shaped turntable includes a radar support mounted above a T-shaped vertical shaft. The load includes load one and load two, respectively mounted on opposite sides of the T-shaped vertical shaft. A pitch drive mechanism is installed inside one of the loads and connected to the T-shaped vertical shaft, used to drive load one and load two to perform pitch movements. The pitch drive mechanism includes a pitch motor, a second stator, a second rotor, and a connecting plate. The pitch motor is an external rotor motor.

Description

Technical Field

[0001] This invention relates to a turntable, and more specifically to a T-shaped turntable driven by an external rotor motor. Background Technology

[0002] Turntables, typically serving as support and rotation platforms, are widely used in high-precision measurement fields such as detection, reconnaissance, and geographic mapping. Their primary function is to provide a highly stable and accurate working platform for various specialized equipment. With the increasing demands for detection and reconnaissance capabilities, designing real-time, efficient, and multifunctional turntables is an urgent need for current detection and reconnaissance systems.

[0003] Traditional turntable mechanisms often focus on a single, specific function, such as optical reconnaissance or radar detection. This single-function design necessitates the coordinated operation of multiple independent systems when facing various complex tasks, increasing system complexity and cost, and reducing overall efficiency. Furthermore, data integration between multiple independent detection and reconnaissance devices presents a challenge. Inconsistent data formats from different devices hinder effective comprehensive analysis and processing, leading to information silos and impacting the timeliness and accuracy of decision-making. This multi-turntable design increases the difficulty of transportation and installation, as well as system maintenance costs. Each repair or component replacement requires significant time and resources, which is detrimental to long-term stable operation. Such a design not only directly affects the detection accuracy of integrated detection and reconnaissance systems, limiting the application scenarios of the entire mechanism, but also indirectly restricts the overall equipment structure design and performance optimization. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a T-shaped turntable driven by an external rotor motor. Its advantages are that the pitch motor is an external rotor motor, and the loads on both sides are connected by a connecting plate, which reduces one driver and improves the synchronization of the loads on both sides. The loads are distributed on both sides of the T-shaped vertical shaft to effectively balance the loads and reduce the impact of off-center load on the turntable accuracy.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A T-shaped turntable driven by an external rotor motor includes a radar support, which is mounted on a T-shaped vertical shaft. The load includes a load one and a load two, which are respectively mounted on both sides of the T-shaped vertical shaft. A pitch drive mechanism is installed inside the load on one side and connected to the T-shaped vertical shaft to drive the load one and the load two to perform pitch motion.

[0007] The pitch drive mechanism includes a pitch motor, a second stator, a second rotor, and a connecting plate. The pitch motor is an external rotor motor. The second stator is connected to a T-shaped vertical shaft, and the second rotor is connected to a first load. The first load is connected to the second load through the connecting plate, so that the pitch motor can simultaneously drive the first and second loads on both sides.

[0008] The main body of the azimuth drive mechanism is installed inside the housing, and the lower part of the housing is installed on the base. The azimuth drive mechanism is used to drive the T-shaped vertical shaft, radar support, and load one and load two to rotate around the vertical direction.

[0009] The pitch drive mechanism also includes a photoelectric encoder II and a deep groove ball bearing. Both load I and load II are connected to the T-shaped vertical shaft through the deep groove ball bearing. The photoelectric encoder II is installed between the pitch motor and load I.

[0010] The orientation drive mechanism includes an orientation motor, a bearing assembly, a stator, a rotor, a photoelectric encoder, an angular contact ball bearing, a conductive slip ring, and an optical path channel. The orientation motor is a torque motor. The stator is connected to the housing, the rotor is connected to the T-shaped vertical shaft, the housing is connected to the base, the conductive slip ring is installed inside the T-shaped vertical shaft, and the other side is connected to the optical path channel. The optical path channel is connected to the load two through the inside of the T-shaped vertical shaft.

[0011] The optical path system includes an optical path conduit and a Couder mirror. The optical path conduit is installed inside the T-shaped vertical axis, Couder mirror one is installed in the base, and Couder mirror two and Couder mirror three are placed perpendicularly to each other inside the T-shaped vertical axis and above the optical path conduit.

[0012] The bearing assembly consists of two opposing angular contact ball bearings installed between the housing and the T-shaped vertical shaft.

[0013] The radar support is connected to a T-shaped vertical shaft, and the radar support and the T-shaped vertical shaft rotate together in azimuth. At the same time, the radar support uses an independent azimuth rotation mechanism inside to support the independent rotation of the load radar.

[0014] It also includes a pitch axis locking device, which includes a driver, a latch, a lock hole and a lock body. The driver and the latch are installed together in the lock body. The lock body is installed above the T-shaped vertical shaft and the lock hole is installed on the side of the load close to the T-shaped vertical shaft.

[0015] It also includes a pitch limiting device, which includes a limiting plate and two baffles. The limiting plate is installed on the outside of the pitch axis of the T-shaped vertical shaft, and the two baffles are installed on the outside of the pitch axis of the load.

[0016] It also includes an azimuth axis locking device, which includes a second driver, a second locking tongue, and a second locking hole. The second driver and the second locking tongue are installed together below the radar support, and the second locking hole is installed on the housing.

[0017] The box has three handles on its outer side.

[0018] The beneficial effects of the T-shaped turntable driven by an external rotor motor of the present invention are:

[0019] 1. Compact structure and simple operation. This invention uses a T-shaped vertical shaft as the core component of the turntable. Its structure is compact, the overall mechanism occupies little space, and it is also equipped with an optical path to meet the detection requirements. The azimuth rotation mechanism can achieve 360-degree continuous rotation, and the pitch rotation mechanism can achieve rotation within the range of -15° to 85°, which is convenient for detection needs.

[0020] 2. Enables high-precision synchronous operation of dual loads. This invention connects the loads on both sides via a connecting plate, allowing the external rotor motor to drive both loads simultaneously. This ensures that the loads on both sides remain at the same pitch angle during operation, guaranteeing synchronization between the loads. It is suitable for scenarios with a large number and variety of loads, such as large loads and integrated detection and reconnaissance systems.

[0021] 3. The added pitch and azimuth locking devices ensure the tightening requirements of the turntable during non-working states such as transportation, increasing safety and reducing the risk of damage. Attached Figure Description

[0038] like Figure 1-6 As shown, a T-shaped turntable driven by an external rotor motor includes a base 1, a housing 2, a radar support 3, a load 4, a T-shaped vertical shaft 5, an azimuth drive mechanism 6, a pitch drive mechanism 7, a pitch limiting device 8, a pitch locking device 9, and an azimuth locking device 10. The radar support 3 is installed above the T-shaped vertical shaft 5. The load 4 includes a first load 4.1 and a second load 4.2, which are respectively installed on both sides of the T-shaped vertical shaft 5. The pitch drive mechanism 7 is installed inside one side of the load 4 and connected to the T-shaped vertical shaft 5, and is used to drive the first load 4.1 and the second load 4.2 to perform pitch movement.

[0039] The pitch drive mechanism 7 includes a pitch motor, a second stator 7.1, a second rotor 7.2, and a connecting plate 7.5. The pitch motor is an external rotor motor. The second stator 7.1 is connected to the T-shaped vertical shaft 5, and the second rotor 7.2 is connected to the first load 4.1. The first load 4.1 is connected to the second load 4.2 through the connecting plate 7.5, so that the pitch motor can drive the first load 4.1 and the second load 4.2 on both sides at the same time.

[0040] This application uses an external rotor motor for the pitch motor, and connects the loads 4 on both sides via a connecting plate 7.5, reducing the need for a driver while improving the synchronization of the loads 4 on both sides. The loads 4 are distributed on both sides of the T-shaped vertical shaft 5, effectively balancing the load and reducing the impact of off-center load on the turntable accuracy.

[0041] The pitch rotation process is driven by a pitch motor. The stator 7.1 of the pitch motor is fixedly connected to the T-shaped vertical shaft 5, so that the stator 7.1 of the pitch motor remains stationary in the pitch direction along with the T-shaped vertical shaft 5. The rotor 7.2 of the azimuth motor is fixedly connected to the load 4.1, the load 4.1 is fixedly connected to the connecting plate 7.5, and the connecting plate 7.5 is fixedly connected to the load 4.2. During the azimuth rotation process, the rotor 7.2 of the azimuth motor drives the load 4.1 and the load 4.2 to move synchronously.

[0042] The main body of the azimuth drive mechanism 6 is installed inside the housing 2, and the lower part of the housing 2 is installed on the base 1. The azimuth drive mechanism 6 is used to drive the T-shaped vertical shaft 5, the radar support 3, and the load 1 4.1 and load 2 4.2 to rotate around the vertical direction.

[0043] The pitch drive mechanism 7 also includes a photoelectric encoder 7.3 and a deep groove ball bearing 7.4. Load 4.1 and load 4.2 are both connected to the T-shaped vertical shaft 5 via the deep groove ball bearing 7.4. The photoelectric encoder 7.3 is installed between the pitch motor and load 4.1. The function of the photoelectric encoder 7.3 is to measure the rotation angle and rotation speed of the pitch motor.

[0044] The orientation drive mechanism 6 includes an orientation motor, a bearing assembly, a stator 6.1, a rotor 6.2, a photoelectric encoder 6.3, an angular contact ball bearing 6.4, a conductive slip ring 6.5, and an optical path channel 11.1. The orientation motor is a torque motor. The stator 6.1 is connected to the housing 2, and the rotor 6.2 is connected to the T-shaped vertical shaft 5. The housing 2 is connected to the base 1. The conductive slip ring 6.5 is installed inside the T-shaped vertical shaft 5, and its other side is connected to the optical path channel 11.1. The optical path channel 11.1 is connected to the load 4.2 through the inside of the T-shaped vertical shaft 5. The photoelectric encoder 6.3 measures the rotation angle and rotation speed of the orientation motor.

[0045] The optical path system 11 includes an optical path conduit 11.1 and a Coud mirror. The optical path conduit 11.1 is installed inside the T-shaped vertical axis 5, the first Coud mirror 11.2 is installed in the base 1, and the second Coud mirror 11.3 and the third Coud mirror 11.4 are placed perpendicularly to each other inside the T-shaped vertical axis 5 and above the optical path conduit 11.1.

[0046] The optical path operation process is as follows: the laser is emitted from the base 1, reflected by the first Kuder mirror 11.2, and then emitted through the optical path channel 11.1 to the second Kuder mirror 11.3. After continuous reflection by the second Kuder mirror 11.3 and the third Kuder mirror 11.4, the laser is emitted through the T-shaped vertical axis 5 and into the second load 4.2, providing laser support for the second load 4.2.

[0047] The azimuth rotation process is driven by an azimuth motor. The stator 6.1 of the azimuth motor is fixedly connected to the housing 2, and the housing 2 is fixedly connected to the base 1, so that the stator 6.1 of the azimuth motor remains stationary. The rotor 6.2 of the azimuth motor is fixedly connected to the T-shaped vertical shaft 5, and the T-shaped vertical shaft 5 is connected to the loads 4 on both sides and the radar support 3. During the azimuth rotation process, the rotor 6.2 of the azimuth motor drives the T-shaped vertical shaft 5 to move synchronously with the loads 4 on both sides and the radar support 3.

[0048] The bearing assembly consists of two opposing angular contact ball bearings 6.4 mounted between the housing 2 and the T-shaped vertical shaft 5. It can withstand radial forces and axial forces in both directions, improving the stability of the shaft system.

[0049] The orientation motor is a torque motor, which allows the optical path duct 11.1, the T-shaped vertical shaft 5, the orientation motor, and the housing 2 to be arranged in a concentric circle, making the structure more compact. The T-shaped vertical shaft 5 is installed in the housing 2 by two oppositely placed angular contact ball bearings 6.4. This bearing combination ensures the stability of the T-shaped vertical shaft 5 while reducing the space it occupies.

[0050] The radar support 3 is connected to the T-shaped vertical shaft 5. The radar support 3 and the T-shaped vertical shaft 5 rotate together in azimuth. At the same time, the radar support 3 adopts an independent azimuth rotation mechanism to support the independent rotation of the load radar.

[0051] It also includes a pitch axis locking device 9, which includes a driver 9.1, a latch 9.2, a locking hole 9.3 and a lock body 9.4. The driver 9.1 and the latch 9.2 are installed together in the lock body 9.4. The lock body 9.4 is installed above the T-shaped vertical shaft 5, and the locking hole 9.3 is installed on the side of the load close to the T-shaped vertical shaft 5.

[0052] The pitch locking process is initiated by the pitch drive mechanism 7 driving the load 4 to the designated position, and the driver 9.1 drives the locking tongue 9.2 to insert into the lock hole 9.3 to complete the locking.

[0053] It also includes a pitch limiting device 8, which includes a limiting plate 8.1 and two baffles 8.2. The limiting plate 8.1 is installed on the outside of the pitch axis of the T-shaped vertical shaft 5, and the two baffles 8.2 are installed on the outside of the pitch axis of the load-4.1.

[0054] It also includes an azimuth axis locking device 10, which includes a second driver 10.1, a second locking tongue 10.2 and a second locking hole 10.3. The second driver 10.1 and the second locking tongue 10.2 are installed together below the radar support 3, and the second locking hole 10.3 is installed on the housing 2.

[0055] The directional locking process is initiated by the directional drive mechanism 6 driving the T-shaped vertical shaft 5 to rotate to the designated position, and the second driver 10.1 driving the second locking tongue 10.2 to insert into the second locking hole 10.3 to complete the locking.
