[0035] The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. In fact, many different examples can be described and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure of the invention will be thorough and complete, and will fully convey the scope of the disclosure of the invention to those skilled in the art.

[0036] As Figures 1-3 shown, the servo drive device corresponding to this embodiment for a radar optoelectronic integrated reconnaissance system generally includes an optoelectronic servo drive component at the lower part and a radar servo drive component at the upper part, and specifically includes an optoelectronic servo bottom plate 1, an optoelectronic servo base 2, an optoelectronic servo platform lower cover 3, an optoelectronic drive core assembly 4, an optoelectronic servo platform upper cover 5, an opto-radar servo interface base 6, a lock base 7, a quick indexing lock 8, a cable cover 9, a wire tying rack 10, a radar servo base 11, a radar servo motor assembly 12, a radar servo assembly housing 13, and a rotor mounting plate 14.

[0037] Among them, the optoelectronic servo drive component is composed of the optoelectronic servo bottom plate 1, the optoelectronic servo base 2, the optoelectronic servo platform lower cover 3, the optoelectronic servo platform upper cover 5, the opto-radar servo interface base 6, the lock base 7, the quick indexing lock 8, and the cable cover 9 surrounding the optoelectronic drive core assembly 4. The radar servo drive component is composed of the wire tying rack 10, the radar servo base 11, the radar servo assembly housing 13, and the rotor mounting plate 14 surrounding the radar servo motor assembly 12. The two components are docked through a cylindrical mechanical interface with a limit, and positioned and locked with an indexing lock.

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

[0039] The lock base 7 and the quick indexing lock 8 are fixed on the optical thunder servo interface base 6 by screws to form a quick disassembly mechanism. The cable shield 9 is installed on the upper side of the optical thunder servo interface base 6 to protect the internal cables.

[0040] As Figures 4-5 shown, the optoelectronic drive core assembly 4 includes a substrate 401, a load pitching shaft 402, a bearing bracket 403, a deep groove ball bearing 404, a bearing gland 405, a C-shaped shaft 406, a limit post 407, a limiter 408, a pitching motor shaft 409, a motor bracket 410, an optoelectronic azimuth servo motor assembly 411 and an optoelectronic pitching servo motor assembly 412. The inner ring of the deep groove ball bearing 404 is fixedly connected coaxially with the load pitching shaft 402, and the outer ring is fixedly connected with the bearing bracket 403. The load pitching shaft 402, the C-shaped shaft 406, the pitching motor shaft 409 and the optoelectronic pitching servo motor assembly 412 are coaxially fixedly connected, and the load pitching shaft 402 can be docked and installed with an optoelectronic detection system.

[0041] The bearing bracket 403 is fixed on the substrate 401 by screws and positioning pins. The outer ring of the deep groove ball bearing 404 is fixed on the bearing bracket 403 by the bearing gland 405. Two limiters 408 are installed on the bearing bracket 403 at a certain angle. The load pitching shaft 402 is matched with the inner ring of the deep groove ball bearing 404, and then is positioned and driven with one end of the C-shaped shaft 406 by a key. A limit post 407 is installed at this end of the C-shaped shaft 406. The other end of the C-shaped shaft 406 is fixed on the pitching motor shaft 409 by a key and a dowel pin. The pitching motor shaft 409 is installed on the rotor of the optoelectronic pitching servo motor assembly 412 by screws and positioning pins. The stator of the optoelectronic pitching servo motor assembly 412 is fixed on the motor bracket 410 by positioning pins and screws. The motor bracket 410 is installed on the substrate 401 by screws and positioning pins.

[0042] The above components can form a pitching axis system. Driven by the optoelectronic pitching servo motor assembly 412, the axis system can rotate in the pitching direction. At the same time, under the action of the limiter 408, the pitching angle range can be limited to prevent excessive or out-of-control rotation. After the pitching axis system is installed on the substrate 401, the substrate 401 is then fixed on the optoelectronic azimuth servo motor assembly 411. The outside of the optoelectronic azimuth servo motor assembly 411 is the stator part, and the inside is the rotor part. Driven by the optoelectronic azimuth servo motor assembly 411, the substrate 401 can rotate in the azimuth direction.

[0043] Regarding the radar servo drive component, the wire binding frame 10 is installed inside the radar servo base 11, which is used for bundling wire harnesses. The radar servo base 11 is the base of the drive component and is designed with a positioning and guiding 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 through 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 through screws and positioning pins. The radar servo assembly outer cover 13 is fixed to the lower side of the outer ring of the rotor mounting plate 14 through screws. The radar sensor is installed on the upper side of the rotor mounting plate 14 through a transition piece. The radar servo motor assembly 12 can drive the radar servo assembly outer 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, while the lower optoelectronic servo drive component can rotate in the azimuth and pitch directions.

[0045] The purpose of presenting the examples and descriptions is to show the description of different advantageous arrangements, but this description is not intended to be exclusive or limited to the examples of the disclosed forms. Many modifications and variations will be obvious to those skilled in the art. Additionally, different advantageous examples may describe different advantages compared to other advantageous examples. The selected example or examples are chosen and described in order to best illustrate the principles of the examples, practical applications, and to enable those of ordinary skill in the art to understand the various examples of the present disclosure that have been modified for the particular use envisioned.
