Description

Technical Field

[0001] This application generally relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to an optoelectronic pod. Background Technology

[0002] A lightweight optoelectronic pod mounted on a drone can detect moving targets below during flight. The detection payload within the pod can rotate under controlled rotation relative to the drone body. The pitch control module for controlling the payload's rotation is typically mounted on the payload frame, while the data transfer module for receiving control information and transmitting detection data is typically mounted on a support frame. The payload frame mounts the detection payload, while the support frame secures the pod to the drone body. Due to the numerous interfaces required for interaction, these two modules are generally connected using printed circuit board (PCB) lead busbars. However, during payload frame rotation, the PCB lead busbars twist, generating significant resistance despite their flexibility. This prevents the detection payload from acquiring accurate data during detection. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an optoelectronic pod that can improve the accuracy of detection data.

[0004] The specific technical solution is as follows:

[0005] This application provides an optoelectronic pod, comprising:

[0006] A rotary drive mechanism, the rotary drive mechanism comprising a rotor assembly and a stator assembly;

[0007] A support frame on which the stator assembly of the rotary drive mechanism is connected;

[0008] A load frame, the inside of which is used to install the detection load, and the outside of which is connected to the rotor assembly of the rotary drive mechanism, the rotor assembly being used to drive the load frame to rotate around a first axis.

[0009] A connecting bearing is provided, wherein the inner side of the connecting bearing is connected to the support frame and the outer side is connected to the load frame, and the first axis is the axis of the connecting bearing.

[0010] A relay mechanism includes a pitch control module, a data transfer module, and a flexible printed circuit board (PCB) conductor bar. One end of the flexible PCB conductor bar is connected to the data transfer module, and the other end is connected to the pitch control module and the detection load. The pitch control module is mounted on the load frame and is configured to receive control signals and control the rotor assembly's movement according to the control signals. The data transfer module is mounted on the support frame and is configured to receive control information from the user terminal, convert it into control signals and send them to the pitch control module, and transmit the data detected by the detection load back to the user terminal. The control information includes rotation direction and rotation angle information. The flexible PCB conductor bar is located inside the connecting bearing and bypasses the first axis.

[0011] Optionally, the flexible printed circuit board lead array is configured as a Z-shape.

[0012] Optionally, a pressure plate is also included, which is disposed on the load frame and is used to block the middle part of the flexible printed circuit board lead array inside the connecting bearing.

[0013] Optionally, the load frame, driven by the rotary drive mechanism, can rotate within a range of -90 degrees to 90 degrees.

[0014] Optionally, the rotatable range of the load frame under the drive of the rotary drive mechanism is 0 degrees with the horizontal plane as the reference.

[0015] Optionally, the rotary drive mechanism is a drive motor.

[0016] The beneficial effects of this application are:

[0017] In this design, the middle portion of the flexible printed circuit board (PCB) conductor bar is wound around the first axis several times. During the rotation of the load frame, the middle portion of the PCB conductor bar tightens or relaxes accordingly, its deformation resembling the tensioning or unwinding of a spring. This effectively reduces the impact of the stress generated by its own deformation on the rotation of the load frame, resulting in a more precise positioning of the load frame during rotation and more accurate data detection.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figure 1 The photoelectric pod provided in this embodiment, which can improve the accuracy of detection data, includes:

[0027] A rotary drive mechanism, the rotary drive mechanism comprising a rotor assembly and a stator assembly;

[0028] Support frame 1, on which the stator assembly of the rotary drive mechanism is connected;

[0029] The load frame 2 has a probe load installed inside and a rotor assembly of the rotary drive mechanism connected to its outside. The rotor assembly is used to drive the load frame 2 to rotate around a first axis.

[0030] A connecting bearing 3 is provided, with its inner side connected to the support frame 1 and its outer side connected to the load frame 2. The first axis is the axis of the connecting bearing 3.

[0031] The relay mechanism includes a pitch control module 41, a data transfer module 42, and a flexible printed circuit board (PCB) lead bus 43. One end of the flexible PCB lead bus 43 is connected to the data transfer module 42, and the other end is connected to the pitch control module 41 and the detection load. The pitch control module 41 is mounted on the load frame 2 and is configured to receive control signals and control the rotor assembly according to the control signals. The data transfer module 42 is mounted on the support frame 1 and is configured to receive control information sent by the user terminal, convert it into control signals and send them to the pitch control module 41, and transmit the data detected by the detection load back to the user terminal. The control information includes rotation direction and rotation angle information. The middle part of the flexible PCB lead bus 43 is located inside the connecting bearing 3 and bypasses the first axis.

[0032] In this design, the middle portion of the flexible printed circuit board lead array 43 is wound around the first axis several times. During the rotation of the load frame 2, the middle portion of the flexible printed circuit board lead array 43 will tighten or relax accordingly, its deformation resembling a "spring." This effectively reduces the impact of the stress generated by its own deformation on the rotation of the load frame 2. Therefore, the position of the load frame 2 during rotation is more precise, and the detected data is more accurate.

[0033] In a preferred embodiment that further ensures the accuracy of the detection data, the flexible printed circuit board lead array 43 is configured as a Z-shape.

[0034] like Figure 2 and Figure 3 As shown, the flexible printed circuit board lead bus 43 follows a "Z" shape. The angles between its two ends and the middle can be determined based on the relative positions of the pitch control module 41 and the data transfer module 42 with the connecting bearing 3. It should be ensured that after installation, the end of the flexible printed circuit board lead bus 43 connected to the data transfer module 42 will not undergo torsional deformation, while the end connected to the pitch control module 41 is positioned at the midpoint of the rotatable stroke of the load frame 2. This minimizes the torsional deformation at the end of the flexible printed circuit board lead bus 43 connected to it during load frame 2 rotation, thus minimizing the impact on the accuracy of the data detected by the detection load.

[0035] In a preferred embodiment that ensures the operational stability of the optoelectronic pod, a pressure plate 5 is also included. The pressure plate 5 is disposed on the load frame 2 and is used to block the middle part of the flexible printed circuit board lead array 43 inside the connecting bearing 3.

[0036] like Figure 4As shown, since the end of the flexible printed circuit board (PCB) lead bus 43 connected to the load frame 2 rotates with the rotation of the load frame 2, the middle part of the PCB lead bus 43, which is coiled inside the connecting bearing 3, may fall out. Under the influence of the rotation of the load frame 2 or the flight attitude of the UAV, the PCB lead bus 43 may become entangled with other structures on the UAV, causing the connection at both ends of the PCB lead bus 43 to break. In this solution, since the pressure plate 5 is added to the load frame 2, the above situation can be effectively avoided, thereby effectively ensuring the stability of the optoelectronic pod operation.

[0037] During the flight of the UAV and the detection of the target, the detection payload, driven by the rotary drive mechanism, can rotate within a range of -90 degrees to 90 degrees with the horizontal plane as 0 degrees, which can effectively cover the UAV's needs for target data detection.

[0038] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
