When the connecting head cooperates with the connecting cover, the adapter block extends into the gap, and the adapter block is driven to rotate by the connecting head.

An adapter block is provided at both ends of each limit block. The positioning assembly is connected to the rotating shaft, and the positioning assembly is used to selectively position or move the limit block relative to the connecting cover.

[0008] By adopting the above technical scheme, the optoelectronic pod adapter structure can achieve rapid installation and disassembly, thereby improving work efficiency; the design of the connector and the connector cover enables the optoelectronic pod to be easily docked with the aircraft, avoiding the cumbersome operation of the traditional bolt tightening method; the coordinated design of the adapter block and the adapter slot not only simplifies the installation process, but also improves the stability of the connection; specifically, when the optoelectronic pod needs to be installed, the connector is first inserted into the connector cover, at which time the adapter block will extend into the gap between the adapter slots, and as the connector rotates around its own axis, the adapter block will rotate in the gap and gradually enter the adapter slot, while pushing the limit block out of the adapter slot; when the adapter block is completed After fully entering the adapter slot, the limit block will be kept outside the adapter slot under the action of the positioning assembly and limited relative to the connection cover to prevent the adapter block from rotating in the opposite direction, thereby achieving a firm lock and enhancing the safety and reliability of the connection; when the optoelectronic pod needs to be disassembled, the position lock of the limit block is released by the positioning assembly, and the connector is rotated in the opposite direction to make the limit block return to the adapter slot, and the connector can be easily pulled out to complete the disassembly process. The entire connection and disassembly process is simple and quick, which improves the working efficiency.

[0012] By adopting the above technical solution, the reset component can realize the automatic reset function of the rotating shaft. When the adapter block is disengaged from the adapter slot, the first elastic member drives the rack to move, and then the rotating shaft is rotated and reset to the initial state through the meshing action of the gear and the rack. The rotation of the rotating shaft will reset the limit block to the adapter slot again, which is convenient for the next quick installation and disassembly of the optoelectronic pod, simplifies the disassembly and assembly process, improves work efficiency, and helps to ensure the accuracy and reliability of each reconnection.

Unless otherwise specified, the orientation words used in the present application, such as "inside" and "outside", refer to the contours of the corresponding parts themselves.

[0044] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses an optoelectronic pod adapter structure (hereinafter referred to as "adapter structure"). The adapter structure includes a connector 1, a connection cover 2 and a limit mechanism 3, which is used to detachably connect the optoelectronic pod 100 to the aircraft.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the first end of the connector 1 is connected to the optoelectronic pod 100, and the second end of the connector 1 is provided with two sets of adapter blocks 11, and the two sets of adapter blocks 11 are symmetrical about the axis center of the connector 1. The connection cover 2 is connected to the aircraft, and the connection cover 2 is provided with two sets of adapter grooves 21, and the two sets of adapter grooves 21 are arranged at intervals along the circumference of the connection cover 2. There is a gap 22 between the adapter grooves 21 so that the adapter blocks 11 can be inserted into the connection cover 2. The adapter blocks 11 are used to hook and cooperate with the adapter grooves 21, so that the connector 1 can be connected to the connection cover 2.

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting mechanism 3 includes a rotating shaft 31, a positioning assembly 32 and two groups of limiting blocks 33. The rotating shaft 31 is rotatably connected to the connecting cover 2, and the axis of the rotating shaft 31 coincides with the axis of the connecting cover 2. The limiting blocks 33 are fixedly connected to the outer peripheral surface of the rotating shaft 31, and the two groups of limiting blocks 33 are symmetrically arranged on both sides of the axis of the rotating shaft 31, and the limiting blocks 33 are slidably connected to the connecting cover 2. In the initial state, the limiting blocks 33 are located in the adapter groove 21; when the connector 1 is matched with the connecting cover 2, the adapter block 11 extends into the gap 22, and the adapter block 11 is driven to rotate through the connector 1, so that the adapter block 11 extends into the adapter groove 21 and pushes the limiting blocks 33 out of the adapter groove 21, so that the limiting blocks 33 and the adapter blocks 11 are arranged circumferentially at intervals, and an adapter block 11 is provided at both ends of each limiting block 33. The positioning assembly 32 is connected to the rotating shaft 31 . The positioning assembly 32 is provided with two groups. The positioning assembly 32 is provided correspondingly to the limit block 33 . The positioning assembly 32 is used to selectively position or move the limit block 33 and the connecting cover 2 relative to each other.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, when the optoelectronic pod 100 needs to be installed, the connector 1 is first inserted into the connecting cover 2 along the axial direction of the connector 1. At this time, the adapter block 11 will extend into the gap 22 between the adapter grooves 21; as the connector 1 rotates around its own axis, the adapter block 11 will rotate in the gap 22 and gradually enter the adapter groove 21, while pushing the limit block 33 out of the adapter groove 21 to achieve the cooperation between the adapter block 11 and the adapter groove 21.

[0048] like Figure 1 , Figure 3 and Figure 4As shown, when the adapter block 11 completely enters the adapter slot 21, the limit block 33 will be kept outside the adapter slot 21 under the action of the positioning assembly 32, and will be relatively limited with the connection cover 2 to prevent the adapter block 11 from rotating in the opposite direction, thereby achieving a firm lock and enhancing the safety and reliability of the connection. When the optoelectronic pod 100 needs to be disassembled, the position lock of the limit block 33 is released by the positioning assembly 32, and the connector 1 is rotated in the opposite direction to make the limit block 33 return to the adapter slot 21, and the connector 1 can be easily pulled out to complete the disassembly process. The entire connection and disassembly process is simple and fast, which improves the work efficiency. The limit mechanism 3 enables the adapter block 11 to rotate to the correct position and achieve limit through the coordinated action of the rotating shaft 31, the positioning assembly 32 and the limit block 33, thereby reducing the risk of accidental detachment. The adapter structure can achieve quick installation and disassembly, improving work efficiency; the design of the connector 1 and the connection cover 2 allows the optoelectronic pod 100 to be easily docked with the aircraft, avoiding the cumbersome operation of the traditional bolt fastening method; the matching design of the adapter block 11 and the adapter slot 21 not only simplifies the installation process, but also improves the stability of the connection.

[0049] Optionally, a flexible pad is provided on one side of the adapter block 11 close to the connector 1, and the flexible pad is used to cooperate with the bottom of the adapter slot 21. The flexible pad can effectively reduce the hard contact between the adapter block 11 and the bottom of the adapter slot 21, reduce wear, and extend the service life. At the same time, the flexible pad can also improve the sealing performance between the adapter block 11 and the adapter slot 21, prevent dust and moisture from entering, and can clean impurities in the adapter slot 21, thereby enhancing the reliability and stability of the connection. The flexible pad can be a rubber pad, and the flexible pad can also play a vibration reduction role on the optoelectronic pod 100 to improve reliability.

[0050] like Figure 5 , Figure 6 and Figure 7 As shown, optionally, the adapter block 11 and the stopper block 33 both have an arc, and the two sets of adapter blocks 11 and the two sets of stopper blocks 33 can form a ring. The adapter block 11 and the stopper block 33 both have an arc and can form a ring, so that the connection between the optoelectronic pod 100 and the aircraft is tighter and more stable, improving the stability and reliability of the connection, and reducing the impact of vibration and impact caused by changes in the external environment on the connection structure, further improving the stable working performance of the optoelectronic pod 100 in a complex environment. At the same time, the ring design also helps to improve the aesthetics and overall coordination of the connection.

[0051] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the limit mechanism 3 also includes a reset component 34. The reset component 34 is used to drive the rotating shaft 31 to reset, so that the limit block 33 is reset to the adapter slot 21 after the adapter block 11 is separated from the adapter slot 21. The design of the limit mechanism 3 improves the stability after connection and prevents loosening or falling off due to external environmental factors. In addition, the introduction of the reset component 34 further improves the reliability and convenience of the connection. In the process of the adapter block 11 withdrawing from the adapter slot 21, the reset component 34 can automatically restore the limit block 33 to its initial position, simplifying the subsequent re-installation operation process. The adapter structure can not only achieve rapid disassembly and assembly and improve work efficiency, but also automatically reset the limit block 33 after disassembly, avoiding the inconvenience caused by complete manual reset.

[0052] Optionally, the reset assembly 34 includes a gear 341, a rack 342 and a first elastic member 343. The upper end of the rotating shaft 31 is rotatably connected to the top of the connecting cover 2, the gear 341 is sleeved on the outer periphery of the rotating shaft 31, the rack 342 is slidably connected to the top of the connecting cover 2, and the rack 342 is meshed with the gear 341. One end of the first elastic member 343 is connected to the end of the rack 342, and the other end of the first elastic member 343 is connected to the connecting cover 2. When the adapter block 11 is separated from the adapter slot 21, the first elastic member 343 can drive the rack 342 to move, so that the gear 341 drives the rotating shaft 31 to rotate and reset to the initial state. The reset assembly 34 can realize the automatic reset function of the rotating shaft 31. When the adapter block 11 is disengaged from the adapter slot 21, the first elastic member 343 drives the rack 342 to move, and then the rotating shaft 31 is rotated and reset to the initial state through the meshing action of the gear 341 and the rack 342. The rotation of the rotating shaft 31 will cause the limit block 33 to reset to the adapter slot 21 again, which is convenient for the next quick installation and disassembly of the optoelectronic pod 100, simplifies the disassembly and assembly process, improves work efficiency, and helps to ensure the accuracy and reliability of each reconnection.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the limiting mechanism 3 includes an auxiliary component 35, and the auxiliary component 35 includes a connecting plate 351 and a second elastic member 352. The connecting plate 351 is provided at the end of the limiting block 33, and the connecting plate 351 moves in the gap 22. One end of the second elastic member 352 is connected to the connecting plate 351, and the other end of the second elastic member 352 is connected to the connecting cover 2. When the limiting block 33 moves out of the transfer groove 21, the second elastic member 352 is subjected to tension, and the second elastic member 352 is used to drive the limiting block 33 to return to the transfer groove 21 when the transfer block 11 moves out of the transfer groove 21. When the transfer block 11 moves out of the transfer groove 21, the second elastic member 352 is subjected to tension and stores energy. When the adapter block 11 is completely separated from the adapter slot 21, the second elastic member 352 releases energy, driving the connecting plate 351 and the stop block 33 to reset to the adapter slot 21, thereby assisting the reset assembly 34 to realize the automatic reset function of the stop block 33, improving the convenience and work efficiency of disassembly and assembly between the optoelectronic pod 100 and the aircraft. The second elastic member 352 is in a bent state in the initial state, which can facilitate the identification of the current position of the stop block 33 through the second elastic member 352 protruding from the lower surface of the connecting cover 2.

[0054] like Figure 3 , Figure 4 and Figure 8 As shown, optionally, the connection cover 2 is provided with an inner peripheral wall 23, the adapter groove 21 and the gap 22 are distributed on the outer side of the inner peripheral wall 23, the inner peripheral wall 23 is provided with a positioning hole 231, and the limit block 33 is provided with a positioning groove 331. The positioning component 32 can be extended and retracted in a direction perpendicular to the axis of the rotating shaft 31, and the positioning component 32 can be inserted into the positioning hole 231 and the positioning groove 331, so that the limit block 33 and the connection cover 2 are relatively positioned to limit the reverse rotation of the adapter block 11. The connection cover 2 is provided with an inner peripheral wall 23, and the adapter groove 21 and the gap 22 are distributed on the outer side of the inner peripheral wall 23. This design makes the matching of the connector 1 and the connection cover 2 tighter, and enhances the stability and reliability of the connection. By inserting the positioning component 32 into the positioning hole 231 and the positioning groove 331, the limit block 33 and the connection cover 2 are relatively positioned to limit the reverse rotation of the adapter block 11, which can not only improve the stability after connection, but also help reduce the risk of accidental falling off and improve safety.

[0055] like Figure 3 , Figure 4 and Fig. 9As shown, optionally, the positioning assembly 32 includes a fixed cylinder 321, a telescopic rod 322 and a third elastic member 323. The first end of the fixed cylinder 321 is fixedly connected to the rotating shaft 31, so that the positioning assembly 32 can rotate with the rotation of the rotating shaft 31. The first end of the telescopic rod 322 is slidably arranged in the second end of the fixed cylinder 321, and the third elastic member 323 is arranged in the fixed cylinder 321. One end of the third elastic member 323 is connected to the first end of the fixed cylinder 321, and the other end of the third elastic member 323 is connected to the first end of the telescopic rod 322. The second end of the telescopic rod 322 is used to extend into the positioning hole 231 and the positioning groove 331. The telescopic rod 322 is always aligned with the positioning groove 331 and rotates synchronously. When the positioning hole 231 is aligned with the positioning groove 331, the telescopic rod 322 can pass through the positioning hole 231 and be inserted into the positioning groove 331 to achieve positioning. A sliding support member can be provided between the fixed tube 321 and the bottom of the connecting cover 2 to ensure the telescopic reliability of the telescopic rod 322; the end of the telescopic rod 322 away from the third elastic member 323 can be a spherical surface. When the telescopic rod 322 is not aligned with the positioning hole 231, the spherical end of the telescopic rod 322 slides relative to the inner wall 23.

[0056] When the telescopic rod 322 is aligned with the positioning hole 231 and the positioning groove 331 as the rotating shaft 31 rotates, the telescopic rod 322 is automatically extended under the action of the third elastic member 323 and inserted into the positioning hole 231 and the positioning groove 331, thereby realizing the relative positioning of the limit block 33 and the connecting cover 2, reducing the risk of accidental movement of the limit block 33, and ensuring the stable connection between the connector 1 and the connecting cover 2. The elastic force provided by the third elastic member 323 enables the telescopic rod 322 to always remain in an outwardly protruding state, and maintains a good locking effect even in the case of vibration or impact, thereby enhancing safety performance. When disassembly is required, the telescopic rod 322 can be easily pulled out by simply overcoming the elastic force of the third elastic member 323, thus completing the disassembly and assembly process conveniently and quickly, reducing maintenance time and costs. Figure 2 and Fig. 9 As shown, the first elastic member 343, the second elastic member 352 and the third elastic member 323 can all be springs, and the type and size parameters of the springs are selected according to actual needs.

[0057] like Figure 2 , Fig. 9 and Fig.10 As shown, optionally, the limiting mechanism 3 includes a pushing assembly 36, and the pushing assembly 36 is used to push the telescopic rod 322 to retract into the fixed cylinder 321 to release the limiting between the limiting block 33 and the connecting cover 2. Figure 3 , Fig. 9 and Fig.10As shown, the pushing assembly 36 can effectively push the telescopic rod 322 back into the fixed tube 321, quickly release the limit between the limit block 33 and the connecting cover 2, so that the adapter block 11 can be smoothly removed from the adapter slot 21, and convenient disassembly and assembly can be achieved. This design not only simplifies the operation process and improves work efficiency, but also reduces the risk of misoperation caused by manual adjustment, and enhances the reliability and safety of disassembly and assembly.

[0058] like Fig.10 and Fig.11 As shown, optionally, the pushing assembly 36 includes a driving member 361, a connecting shaft 362, a first bevel gear 363, a second bevel gear 364, a lead screw 365, a nut 366 and a guide rod 367. The limiting mechanism 3 includes a support plate 39, which is used to connect the limiting block 33 and the rotating shaft 31, and the axis of the support plate 39 coincides with the axis of the rotating shaft 31. The driving member 361 is connected to the support plate 39, one end of the connecting shaft 362 is transmission-connected to the output end of the driving member 361, the first bevel gear 363 is sleeved on the outer periphery of the connecting shaft 362, the first bevel gear 363 is meshed with the second bevel gear 364, the second bevel gear 364 is fixedly sleeved on the outer periphery of the lead screw 365, the lead screw 365 is parallel to the guide rod 367, the connecting shaft 362, the lead screw 365 and the guide rod 367 are all mounted on the lower side of the supporting plate 39, the nut 366 is screwed to the lead screw 365, and the nut 366 is slidably connected to the guide rod 367, the outer periphery of the telescopic rod 322 is provided with a clamping member 38, the nut 366 is used to push the clamping member 38, so that the telescopic rod 322 can withdraw from the positioning groove 331 and the positioning hole 231. The specific structure of the supporting plate 39 is not limited, as long as it can realize the driving of the limit block 33 and does not affect the integrity of the connecting cover 2.

[0059] like Fig. 9 , Fig.10 and Fig.11As shown, when it is necessary to unlock the limit between the limit block 33 and the connection cover 2, first start the driving member 361, the output end of the driving member 361 drives the connecting shaft 362 to rotate, and the first bevel gear 363 on the connecting shaft 362 rotates accordingly, and drives the second bevel gear 364 to rotate through the meshing relationship. The second bevel gear 364 is installed on the screw member 365. As the second bevel gear 364 rotates, the screw member 365 also rotates synchronously. Since the nut 366 is threadedly connected to the screw member 365 and slidably connected to the guide rod 367, the nut 366 moves linearly along the screw member 365 and the guide rod 367. The nut 366 pushes the clamping member 38, so that the telescopic rod 322 withdraws from the positioning hole 231 and the positioning groove 331, thereby releasing the limit between the limit block 33 and the connection cover 2. At this time, the limit block 33 can move freely, which facilitates the adapter block 11 to be disengaged from the adapter groove 21, and realizes the rapid separation of the optoelectronic pod and the aircraft. The transfer structure can realize quick installation and disassembly, and improve the working efficiency. The meshing design of the second bevel gear 364 and the lead screw 365 ensures the accuracy and reliability of the transmission and avoids the failure problem caused by mechanical wear. A button can be provided on the outside of the connection cover 2, and the button is electrically connected to the driving member 361 to control the start and stop of the driving member 361. The driving member 361 can be a motor that can realize forward and reverse rotation. The forward rotation of the motor releases the limiting effect of the telescopic rod 322 on the limit block 33; the reverse rotation of the motor resets the nut 366, so that the telescopic rod 322 can be extended into the positioning groove 331 again when used next time. When the end of the telescopic rod 322 is not aligned with the positioning groove 331, the nut 366 and the clamping member 38 are arranged at a distance; after the telescopic rod 322 is extended into the positioning groove 331, the clamping member 38 abuts against the nut 366.

[0060] like Figure 2 , Fig.12 and Fig.13 As shown, the adapter groove 21 is provided with an avoidance groove so that the support plate 39 can extend into the adapter groove 21 to achieve connection with the limit block 33.

[0061] It can be understood that the transfer structure also includes necessary structures for connection, support, driving, positioning, limiting and control functions so that the transfer structure can operate normally; the parameters such as shape, size, material and setting quantity of each part of the transfer structure can be determined as needed to achieve the corresponding functions.

[0062] The implementation principle of the optoelectronic pod adapter structure of the embodiment of the present application is as follows: when the optoelectronic pod 100 needs to be installed, the connector 1 is first inserted into the connector cover 2, at which time the adapter block 11 will extend into the gap 22 between the adapter slots 21. As the connector 1 rotates around its own axis, the adapter block 11 will rotate in the gap 22 and gradually enter the adapter slot 21, while pushing the limit block 33 out of the adapter slot 21; when the adapter block 11 completely enters the adapter slot 21, the limit block 33 will remain in the rotation slot 21 under the action of the positioning assembly 32. The outside of the connecting slot 21 is limited relative to the connecting cover 2 to prevent the adapter block 11 from rotating in the opposite direction, thereby achieving a firm lock and enhancing the safety and reliability of the connection; when the optoelectronic pod 100 needs to be disassembled, the position lock of the limit block 33 is released through the positioning component 32, and the connecting head 1 is rotated in the opposite direction to make the limit block 33 return to the adapter slot 21, and the connecting head 1 can be easily pulled out to complete the disassembly process. The entire connection and disassembly process is simple and quick, which improves the working efficiency, reduces the risk of accidental detachment, and improves reliability.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
