Description

Technical Field

[0001] The present invention relates to the technical field of optoelectronic pods, and in particular to an optoelectronic pod structure capable of reducing wire winding of an inner ring frame. Background Art

[0002] An optoelectronic pod is a crucial component of optoelectronic reconnaissance and detection equipment. It is typically mounted on a detection carrier and moves with it. When the detection carrier reaches a set position, the pod's motor controls the rotation of the optoelectronic device, thereby controlling the orientation of the device within it, enabling detection or reconnaissance of the target.

[0003] In the existing optoelectronic pod, the inner ring frame carrying each monomer is driven to rotate by a motor; the wiring harness is introduced from the outer ring frame and directly connected to the motor and monomer components after introduction; in order to achieve the pitch adjustment of the optoelectronic pod, the pitch rotation of the outer ring frame is required, and the wiring harness can only be introduced from the rotation axis position when it is introduced from the outer ring frame; however, because the rotation planes of the outer ring frame and the inner ring frame are perpendicular to each other, this results in the wiring harness being introduced from the outer ring frame at the edge position of the rotation of the inner ring frame; the introduced wiring harness is directly connected to the monomers on the inner ring frame, and the edge position of the inner ring frame will interfere with the wiring harness when it rotates, which is specifically manifested in driving the wiring harness to swing back and forth; the rotation angle of the inner ring wire frame is very small, and the pulling of the wiring harness will affect the motor torque, and the motor accuracy will be greatly affected. The long-term swinging of the wiring harness will also cause wiring harness fatigue and shorten the service life of the wiring harness. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides an optoelectronic pod structure that reduces wire winding on the inner ring frame, thereby solving the problem of wire winding on the inner ring frame when the wire harness entering the outer ring frame is connected to the monomer on the inner ring frame.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A photoelectric pod structure for reducing wire winding on an inner ring frame comprises a cover plate, an outer ring frame, an outer ring wiring groove, an inner ring frame and the inner ring wiring groove; the outer ring frame is rotatably connected inside the cover plate; the inner ring frame is provided inside the outer ring frame, and the outer ring wiring groove is provided between the outer ring frame and the inner ring frame; the inner ring wiring groove is installed on the inner ring frame; the wiring harness is introduced from the outer ring frame, distributed in the outer ring wiring groove, and led out from the wire outlet of the outer ring wiring groove; the led-out wiring harness is connected to each monomer on the inner ring frame through the inner ring wiring groove.

[0007] In this solution, the wiring harness introduced from the outer ring frame is distributed in the outer ring wiring groove, and the force point of the wiring harness is led from the edge position of the inner ring frame to its axial position to avoid interference with the wiring harness during the rotation of the inner ring frame; and the wiring harness is introduced at the axial position of the inner ring frame, the winding force on the inner ring frame is more uniform, and the motion interference between the wiring harness and the inner ring frame is also smaller; the wiring harness led out from the outer ring wiring groove is distributed in the inner ring wiring groove, and the inner ring wiring groove can wrap the scattered wiring harness to prevent it from rubbing against the cover plate.

[0008] Furthermore, an inner ring motor is provided on one side of the inner ring frame, the stator of the inner ring motor is fixed on the outer ring frame, and the rotor of the inner ring motor is fixedly connected to the inner ring frame;

[0009] The other side of the inner ring frame is rotatably connected to the outer ring frame.

[0010] Furthermore, the outer ring wiring groove includes a first arc groove and a second arc groove, the wire inlet of the first arc groove is arranged on the side of the outer ring frame where the wire inlet hole is provided, and the wire outlet of the first arc groove is arranged on the side of the outer ring frame close to the inner ring motor; the wire inlet of the second arc groove is connected to the wire outlet of the first arc groove, and the wire outlet of the second arc groove is arranged on the side of the inner ring motor perpendicular to the plane where the outer ring frame is located.

[0011] In this solution, the first arc groove leads the wiring harness from the edge of the inner ring frame to one side of its axial direction. The swing amplitude of the axial side of the inner ring frame is smaller during the swing, and the interference with the wiring harness is smaller; the second arc groove leads the wiring harness from one side of the horizontal direction of the inner ring motor to one side of its vertical direction. The wiring harness on the inner ring frame will not contact the outer ring frame during the swing, which improves space utilization and avoids friction between the wiring harness and the outer ring frame.

[0012] Furthermore, one side of the inner ring frame is connected to a fixing seat by screws, and the rotor of the inner ring motor is fixedly connected to the inner ring frame through the fixing seat;

[0013] The other side of the inner ring frame is connected to a bearing seat by screws, an inner ring bearing is assembled in the bearing seat, and the inner ring frame is rotatably connected to the outer ring frame through the inner ring bearing.

[0014] Furthermore, the inner ring wiring groove is an arc-shaped structure, one end of the arc-shaped structure is fixed on the inner ring frame; the other end of the arc-shaped structure is provided with a wire inlet, and the wire harness led out from the outer ring wiring groove passes through the wire inlet and is introduced into the inner ring frame.

[0015] In this solution, the wiring harness led out from the outer ring wiring groove is dispersed and connected to each monomer, and the dispersed wiring harness is distributed in the inner ring wiring groove, avoiding friction between the wiring harness and the cover plate during the rotation of the inner ring frame.

[0016] Furthermore, a mounting plate is provided at one end of the inner ring wiring trough, a mounting hole is opened on the mounting plate, and screws are assembled in the mounting holes; the inner ring wiring trough is fixed to the inner ring frame by the screws.

[0017] In this solution, the inner ring wiring groove is fixed by screws, which is convenient for disassembly and installation, and facilitates the maintenance of the wiring harness.

[0018] Furthermore, the wire outlet of the outer ring wiring groove includes a single wire outlet and a motor wire outlet. The single wire outlet is arranged upward perpendicular to the direction of the outer ring frame plane, and the motor wire outlet is arranged downward perpendicular to the direction of the outer ring frame plane.

[0019] In this solution, single-unit wire ports and motor wire ports are set. The wire harnesses led out from the single-unit wire ports are used to connect with each unit on the inner ring frame; the wire harnesses led out from the motor wire ports are used to connect with the inner ring motor. This design makes the wire harness distribution in the overall device more regular.

[0020] Furthermore, mounting holes are provided on the edge of the outer ring wiring groove, and the outer ring wiring groove is connected to the outer ring frame through the mounting holes.

[0021] In this solution, mounting holes are provided, and screws are passed through the mounting holes to mount the outer ring wiring trough on the outer ring frame, which facilitates installation.

[0022] The beneficial effects of the present invention are:

[0023] The optoelectronic pod structure provided by the present invention is designed with an outer ring wiring groove. The outer ring wiring groove can change the point of action on the wiring harness during the left-right swing of the inner ring frame. In existing optoelectronic pod structures, the edge of the inner ring frame pulls and interferes with the wiring harness during swinging, severely affecting the wiring harness. After the outer ring wiring groove is designed, the outer ring wiring groove guides the wiring harness to the axial side of the inner ring frame, reducing the interference with the wiring harness during the swinging of the inner ring frame. The inner ring wiring groove is designed to block the axially distributed wiring harness led out of the outer ring wiring groove, avoiding friction between the wiring harness and the rear cover plate. At the same time, the rotational torque of the inner ring motor can be reduced, and the force on the inner ring motor is evenly distributed during rotation, making the performance of the inner ring motor more stable.

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides an optoelectronic pod structure that reduces the winding of the inner ring frame.
