The radar servo drive component is composed of the wire binding rack 10, the radar servo base 11, the radar servo assembly housing 13 and the rotor mounting plate 14 around the radar servo motor assembly 12. The two components are docked through a cylindrical mechanical interface with a limiter and positioned and locked with an indexing locker.

[0038] The photoelectric servo base plate 1 is an adapter plate between the servo drive device and the tripod or other mounting platform, and corresponding mounting holes can be designed as needed. The photoelectric servo base 2 is the base of the photoelectric drive component, which is a bowl-shaped structure with reserved installation space for wires and circuit components. The lower shield 3 of the photoelectric servo platform and the upper shield 5 of the photoelectric servo platform are protective covers, which are printed with new non-metallic materials, which can not only reduce weight but also facilitate production and manufacturing. They are fixed to the photoelectric drive movement assembly 4 by screws and move with the photoelectric drive movement assembly 4. The photoelectric servo interface base 6 is the mechanical interface between the photoelectric servo drive component and the radar servo drive component. It is installed on the photoelectric drive movement assembly 4 by screws and locating pins, and is docked and locked with the radar servo base 11 at the upper end. It does not move with the photoelectric drive movement assembly 4, and can realize the rotational movement of the photoelectric detection system in the azimuth and pitch directions.

[0039] The locking device base 7 and the fast indexing locking device 8 are fixed on the light-ray servo interface base 6 by screws to form a quick disassembly mechanism. The cable shield 9 is installed on the light-ray servo interface base 6 to protect the internal cables.

[0040] like Figure 4-5 As shown, the photoelectric drive movement assembly 4 includes a base plate 401, a load pitch axis 402, a bearing bracket 403, a deep groove ball bearing 404, a bearing cover 405, a C-shaped axis 406, a limit column 407, a limiter 408, a pitch motor axis 409, a motor bracket 410, a photoelectric azimuth servo motor assembly 411 and a photoelectric pitch servo motor assembly 412. The inner ring of the deep groove ball bearing 404 is coaxially fixedly connected to the load pitch axis 402, and the outer ring is fixedly connected to the bearing bracket 403. The load pitch axis 402, the C-shaped axis 406, the pitch motor axis 409 and the photoelectric pitch servo motor assembly 412 are coaxially fixedly connected, and the load pitch axis 402 can be docked to install a photoelectric detection system.

[0041] The bearing bracket 403 is fixed to the base plate 401 by screws and locating pins, the outer ring of the deep groove ball bearing 404 is fixed to the bearing bracket 403 by a bearing cover 405, two limiters 408 are installed on the bearing bracket 403 at a certain angle, the load pitch axis 402 cooperates with the inner ring of the deep groove ball bearing 404, and then is positioned and driven by a key with one end of the C-type axis 406, and a limiting column 407 is installed at this end of the C-type axis 406, and the other end of the C-type axis 406 is fixed to the pitch motor shaft 409 by keys and pins, and the pitch motor shaft 409 is installed on the rotor of the optoelectronic pitch servo motor assembly 412 by screws and locating pins, and the stator of the optoelectronic pitch servo motor assembly 412 is fixed to the motor bracket 410 by locating pins and screws, and the motor bracket 410 is installed on the base plate 401 by screws and locating pins.

At the same time, the pitch angle range can be limited under the action of the limiter 408 to prevent excessive or uncontrolled rotation. After the pitch axis system is installed on the substrate 401, the substrate 401 is fixed on the photoelectric azimuth servo motor assembly 411. The photoelectric azimuth servo motor assembly 411 has a stator part on the outside and a rotor part on the inside. Under the drive of the photoelectric azimuth servo motor assembly 411, the substrate 401 can rotate in the azimuth direction.

[0043] Regarding the radar servo drive component, the wire tie rack 10 is installed inside the radar servo base 11 and is used to bundle the wire harness. The radar servo base 11 is the base of the drive component and is designed with a positioning guide structure, which can be used as a mechanical interface for docking with the optoelectronic drive component. The stationary part of the radar servo motor assembly 12 is installed on the radar servo base 11 by screws and positioning pins, the rotor mounting plate 14 is installed on the top of the rotor part of the radar servo motor assembly 12 by screws and positioning pins, the radar servo assembly cover 13 is fixed to the lower side of the outer ring of the rotor mounting plate 14 by screws, and the radar sensor is installed on the upper side of the rotor mounting plate 14 by a transition piece. The radar servo motor assembly 12 can drive the radar servo assembly cover 13, the rotor mounting plate 14 and the radar sensor to rotate stably at a certain speed.

[0044] When the entire drive device is working, the upper radar servo drive component can work independently of the optoelectronic servo drive component and rotate in the azimuth direction, and the lower optoelectronic servo drive component can rotate in the azimuth and pitch directions.
