Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping drone technology, and more specifically, to a quick connection structure for an optoelectronic pod of a surveying and mapping drone. Background Technology

[0002] A surveying drone is a type of unmanned aerial vehicle (UAV) specifically designed for geographic information collection. It combines aerial photography, remote sensing, and UAV technology to capture detailed images of the Earth's surface from high altitudes and generate high-precision geographic information data. Equipped with high-precision sensors (such as high-resolution cameras and LiDAR), surveying drones photograph and measure ground or aerial targets, acquiring various types of data, including terrain data and imagery. This data includes not only traditional topographic maps and maps, but also digital elevation models (DEMs), digital surface models (DSMs), orthophoto maps, providing strong support for fields such as urban planning, land management, environmental monitoring, agricultural management, and disaster assessment.

[0003] With the continuous development of UAV technology, surveying UAVs have been widely used in fields such as geographic surveying and environmental monitoring. As an important component of surveying UAVs, the electro-optical pod integrates camera modules, ranging modules, or thermal imaging modules to achieve high-precision data acquisition. However, existing electro-optical pods are mostly installed by securing them to the UAV with multiple bolts. This method is inconvenient for installation and presents several problems during disassembly and maintenance: firstly, multiple bolts need to be loosened one by one, which is cumbersome and time-consuming; secondly, bolts are prone to being lost or damaged, increasing maintenance costs; and finally, frequent disassembly and installation may cause wear and tear on the connection points between the UAV and the electro-optical pod, affecting the equipment's lifespan. Therefore, developing a quick-connect structure to enable rapid installation and disassembly of the electro-optical pod and the UAV is of significant practical importance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a quick-connect structure for the optoelectronic pod of a surveying drone. This structure allows for rapid connection and disassembly of the optoelectronic pod from the drone without the need for multiple bolts. It features convenient operation and a stable connection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-connection structure for a surveying UAV optoelectronic pod includes an upper plate and a lower plate. The upper plate is used to be installed on the surveying UAV, and the lower plate is used to be installed on the optoelectronic pod. The lower plate is provided at intervals on the lower side of the upper plate.

[0007] The upper plate has multiple sets of column sleeves symmetrically fixed on its bottom surface. Each column sleeve has a through-hole. A fixed support rod is fixed at the center of the bottom surface of the upper plate. A rotatable drive turntable is fitted on the fixed support rod. The drive turntable has multiple sets of drive grooves that slope from the edge to the center evenly inside. Two sets of positioning support plates are fixed on the upper plate inside the column sleeves. A locking rod that matches the lock hole is slidably connected through the interior of the left positioning support plate. A connecting rod is slidably connected through the interior of the right positioning support plate. One end of the connecting rod is fixedly connected to the locking rod, and the other end is rotatably connected to the drive groove through a pin. A driven bevel gear is fixedly connected to the upper side of the drive turntable. A driving bevel gear is meshed and driven by the driven bevel gear. A shaft is fixedly connected to the driving bevel gear. The shaft is rotatably connected to the upper plate through a support plate. A knob is installed at the end of the shaft.

[0008] The lower plate has the same specifications as the upper plate. The lower plate is fixed with multiple sets of plug-in rods that correspond one-to-one with the column sleeves. The plug-in rods have positioning holes inside that are adapted to the locking rods. After the plug-in rods are inserted into the column sleeves, they are locked and connected by the locking rods.

[0009] Furthermore, multiple sets of weight-reduction grooves are provided inside both the upper and lower plates.

[0010] Furthermore, multiple sets of positioning holes are provided, and the positioning holes are evenly distributed on the plug rod.

[0011] Furthermore, the drive turntable has multiple sets of limiting holes evenly spaced, and the positions of the limiting holes are offset from the drive slide groove. A fixed shaft is fixedly mounted on the lower plate, and a limiting plate is slidably sleeved on the fixed shaft. A support spring is sleeved on the fixed shaft at the bottom of the limiting plate. Multiple sets of limiting rods corresponding to the limiting holes and with matching specifications are fixedly mounted on the upper side of the limiting plate. A lever is fixedly connected to one side of the limiting plate. A limiting seat is fixedly mounted on the lower plate at a position corresponding to the lever, and the lever is located inside the limiting seat.

[0012] Furthermore, a baffle is fixedly provided on one end of the locking rod near the connecting rod.

[0013] Furthermore, a guide sleeve is fixed on the left side of the positioning support plate corresponding to the locking rod. The guide sleeve corresponds to the lock hole on the column sleeve, and the locking rod extends out from the guide sleeve and is inserted into the lock hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model achieves rapid connection and locking of the upper and lower plates through the design of mechanical structures such as the drive turntable, locking rod, connecting rod, plug-in rod and column sleeve. Simply rotate the knob to drive the drive turntable to rotate through bevel gear transmission, thereby driving the locking rod to extend or retract, completing the connection or unlocking process, and realizing rapid connection and disassembly of the photoelectric pod. This design greatly simplifies the installation and disassembly process of the photoelectric pod, improves operating efficiency, and reduces the time and difficulty of manual operation.

[0016] 2. Compared with the traditional bolt fixing method, this utility model is more convenient to operate. No tools are required. Connection and disassembly can be completed by simply rotating the knob manually, which greatly facilitates on-site operation.

[0017] 3. The design of the locking rod and the plug-in rod in this utility model ensures a firm connection between the upper plate and the lower plate. After the locking rod is inserted into the positioning hole of the plug-in rod, it can effectively prevent the photoelectric pod from loosening or falling off during flight, thus ensuring the stability of the surveying operation.

[0018] 4. The design of the limiting plate and limiting rod in this utility model provides additional safety for the connection structure. During the connection process, the limiting rod can be inserted into the limiting hole on the drive turntable to prevent the drive turntable from accidentally rotating during flight and causing the locking rod to unlock. The design of the lever and the limiting card seat allows the limiting plate to be fixed on the lower plate when not needed, avoiding separation from the drive turntable due to vibration during flight.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] Example:

[0031] like Figures 1 to 9 As shown, a quick connection structure for a surveying UAV optoelectronic pod includes an upper plate 1 and a lower plate 2. The upper plate 1 is used to be installed on the surveying UAV, and the lower plate 2 is used to be installed on the optoelectronic pod. The lower plate 2 is provided at intervals on the lower side of the upper plate 1, thereby achieving quick connection of the optoelectronic pod through the lower plate 2 and the upper plate 1.

[0032] Multiple sets of column sleeves 3 are symmetrically fixed on the bottom surface of the upper plate 1. Locking holes 12 are opened through the inside of the column sleeves 3. A fixed support rod 8 is fixed at the center of the bottom surface of the upper plate 1. A rotatable drive turntable 10 is sleeved on the fixed support rod 8. Multiple sets of drive grooves 17 that are evenly opened inside the drive turntable 10 and inclined from the edge to the center are evenly opened. Two sets of positioning support plates 13 are fixed on the upper plate 1 inside the column sleeves 3. A locking rod 6 that matches the locking hole 12 is slidably connected through the inside of the left positioning support plate 13. A connecting rod 7 is slidably connected through the inside of the right positioning support plate 13. One end of the connecting rod 7 is fixedly connected to the locking rod 6, and the other end is rotatably connected to the drive groove 17 through a pin. A driven bevel gear 15 is fixedly connected to the upper side of the drive turntable 10. A driving bevel gear 16 is meshed and driven on the driven bevel gear 15. A shaft 11 is fixedly connected to the driving bevel gear 16. The shaft 11 is rotatably connected to the upper plate 1 through a support plate 14. A knob 9 is installed at the end of the shaft 11.

[0033] The lower plate 2 has the same specifications as the upper plate 1. Multiple sets of plug-in rods 5, which correspond one-to-one with the column sleeves 3, are fixed on the lower plate 2. The plug-in rods 5 have positioning holes 19 that are compatible with the locking rods 6. After the plug-in rods 5 are inserted into the column sleeves 3, they are locked and connected by the locking rods 6. This design solves the problem that existing optoelectronic pods are usually fixed to the UAV with multiple bolts, which is inconvenient for installation and disassembly, has low operating efficiency, and poor convenience.

[0034] This invention utilizes a mechanical structure consisting of a drive turntable 10, a locking rod 6, a connecting rod 7, a plug-in rod 5, and a column sleeve 3 to achieve rapid connection and locking between the upper plate 1 and the lower plate 2. Simply rotating the knob 9 drives the drive turntable 10 to rotate via bevel gear transmission, which in turn extends or retracts the locking rod 6, completing the connection or unlocking process. This enables rapid connection and disassembly of the photoelectric pod, significantly simplifying the installation and disassembly process, improving operational efficiency, and reducing the time and difficulty of manual operation. Compared to traditional bolt fixing methods, operation is more convenient, requiring no tools; connection and disassembly can be completed simply by manually rotating the knob 9, greatly facilitating on-site operations.

[0035] In this embodiment, multiple sets of weight-reduction grooves 4 are provided inside the upper plate 1 and the lower plate 2. The opening of the weight-reduction grooves 4 effectively reduces the overall weight of the upper plate 1 and the lower plate 2, thereby improving the flight efficiency of the UAV, extending the flight time and reducing energy consumption. At the same time, the weight-reduction grooves 4 make the connection structure lighter, which helps the UAV maintain better flight performance when carrying an electro-optical pod.

[0036] In this embodiment, multiple sets of positioning holes 19 are provided, and the positioning holes 19 are evenly distributed on the plug rod 5. These multiple sets of positioning holes 19 provide multiple connection position options for the upper plate 1 and the lower plate 2, allowing adjustment of the installation connection position of the lower plate 2. During actual installation, appropriate positioning holes 19 can be selected for connection according to the specific layout and connection requirements of the UAV and the electro-optical pod, improving connection flexibility. When the position of the electro-optical pod needs to be adjusted, different positioning holes 19 can be used.

[0037] In this embodiment, multiple sets of limiting holes 18 are evenly provided on the drive turntable 10, and the positions of the limiting holes 18 are offset from the drive slide groove 17. A fixed shaft 25 is fixedly provided on the lower plate 2, and a limiting plate 20 is slidably sleeved on the fixed shaft 25. A support spring 24 is sleeved on the fixed shaft 25 at the bottom of the limiting plate 20. Multiple sets of limiting rods 21 corresponding to the limiting holes 18 and with matching specifications are fixedly provided on the upper side of the limiting plate 20. A lever 23 is fixedly connected to one side of the limiting plate 20. A limiting seat 22 is fixedly provided on the lower plate 2 at the position corresponding to the lever 23, and the lever 23 is located inside the limiting seat 22. By moving the lever 23, the up and down movement of the limiting plate 20 can be easily controlled, thereby realizing the insertion and removal of the limiting rods 21. The limiting seat 22 provides a limiting function for the lever 23, thereby effectively preventing the limiting plate 20 from rotating. When the limiting rod 21 is inserted into the limiting hole 18, the drive turntable 10 cannot continue to rotate, thus limiting the drive turntable 10 and ensuring that it remains stably in the locked state, preventing accidental rotation due to external force that could unlock the locking rod 6. When it is necessary to unlock the drive turntable 10, press down the lever 23. The limiting plate 20 moves downward under the action of the lever 23, thereby pulling the limiting rod 21 out of the limiting hole 18, allowing the drive turntable 10 to rotate freely. When it is necessary to lock the drive turntable 10, release the lever 23. The limiting plate 20 moves upward under the action of the support spring 24, and the limiting rod 21 inserts into the limiting hole 18 on the drive turntable 10, thus achieving limiting and locking.

[0038] In this embodiment, a baffle 61 is fixedly provided on one end of the locking rod 6 near the connecting rod 7. The baffle 61 forms an effective anti-disengagement structure. When the locking rod 6 extends out and is inserted into the positioning hole 19, the baffle 61 will contact the positioning support plate 13 to prevent the locking rod 6 from moving excessively.

[0039] In this embodiment, a guide sleeve 131 is fixed on the left side of the positioning support plate 13 corresponding to the locking rod 6. The guide sleeve 131 corresponds to the locking hole 12 on the column sleeve 3. The locking rod 6 extends out from the guide sleeve 131 and is inserted into the locking hole 12. The guide sleeve 131 provides a guiding effect for the movement of the locking rod 6, so that the locking rod 6 can extend smoothly and accurately, ensuring that the locking rod 6 can be accurately positioned and inserted into the locking hole 12, making the connection process simpler and faster, and improving the accuracy of the connection.

[0040] The working principle of this quick-connect structure for the optoelectronic pod of a surveying UAV:

[0041] In actual use, the upper plate 1 is first installed onto the drone with screws, and the lower plate 2 is then fixed onto the optoelectronic pod with screws. When installing and connecting the optoelectronic pod, first rotate knob 9. Knob 9 drives shaft 11 and the driving bevel gear 16 to rotate. The driving bevel gear 16 drives the driven bevel gear 15 to rotate, which in turn drives the drive turntable 10 to rotate. The rotation of the drive turntable 10 causes the locking rod 6 to move inward, disengaging it from the locking hole 12 of the sleeve 3. Then, the insertion rod 5 on the lower plate 2 is aligned with the sleeve 3 on the upper plate 1 and inserted. Then, knob 9 is rotated in the opposite direction, causing the drive turntable 10 to rotate in reverse. The rotation of the drive turntable 10 causes the locking rod 6 to move outward until it is inserted into the locking hole 12 and the positioning hole 19. The locking rod 6 achieves a stable connection between the insertion rod 5 and the sleeve 3, thus locking the upper plate 1 and the lower plate 2 together. At this time, the limiting plate 20 moves upward under the action of the support spring 24, and the limiting rod 21 is inserted into the limiting hole 18 on the drive turntable 10, thereby realizing the limiting and locking of the drive turntable 10 and preventing it from being accidentally rotated due to external force, which would cause the locking rod 6 to unlock.

[0042] When it is necessary to unlock and disassemble the optoelectronic pod, repeat the above steps in reverse to remove the optoelectronic pod.

[0043] In summary, this quick-connect structure for the electro-optical pod of the surveying UAV enables rapid connection and disassembly between the electro-optical pod and the surveying UAV, greatly improving operational efficiency and ease of use. Compared to the traditional bolt fixing method, it is more convenient to operate, requiring no tools; connection and disassembly can be completed simply by manually rotating knob 9, greatly facilitating on-site operations.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
