Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a replaceable load mounting device for a multi-rotor UAV. Background Art

[0002] With the development of drone technology, the use of drones for transporting goods is becoming more and more popular. Drones are fast and efficient in transporting goods, especially for goods conveyors in special environments, which shows great convenience and advantages over other transportation methods.

[0003] For example, Chinese patent publication number CN218929793U discloses a drone mounting device comprising a multi-rotor drone body, a quick-release component mounted at the bottom of the multi-rotor drone body, a loading box with an open side connected to the bottom of the multi-rotor drone body by means of the quick-release component, a protective storage component mounted within the loading box, and a partitioning component attached to the protective storage component. This utility model facilitates quick and easy disassembly and maintenance of the loading box by means of the quick-release component, and enables quick storage of portable devices by means of a storage drawer, thereby avoiding the need for exposed transportation of the portable devices. Furthermore, the protective storage component within the storage drawer provides comprehensive and flexible protection for the portable devices within the storage drawer, thereby avoiding damage from collisions between adjacent portable devices during transportation. Furthermore, the partitioning component, in conjunction with other components, enables rapid and dynamic spatial division within the storage drawer, enabling quick fine-tuning of the size of the portable devices, thereby improving space utilization.

[0004] However, the above-mentioned drone mounting device does not have the function of convenient disassembly and installation when replacing different loads or equipment. Each time the load is replaced, the user needs to spend a lot of time manually disassembling, adjusting and fixing the load, especially in tasks that require frequent load replacement, which greatly reduces work efficiency. Utility Model Content

[0005] The purpose of the present invention is to provide a replaceable load mounting device for a multi-rotor UAV, so as to solve the problem of inconvenient disassembly and installation when replacing different loads or equipment proposed in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A replaceable load mounting device for a multi-rotor drone comprises: a multi-rotor drone body, two sets of support frames fixedly mounted on the lower surface of a connecting arm of the multi-rotor drone body, the two sets of support frames being opposite to each other, a guide rod fixedly mounted on the center portion of the support frame, a guide block slidably mounted inside the guide rod, and a mounting mechanism fixedly mounted on one inner end of each set of guide blocks.

[0008] Preferably, connecting columns are fixedly installed on both sides of the guide block, so that the guide block can be slidably installed between the guide rods through the connecting columns, so that the guide block can drive the installation mechanism installed at one end to slide vertically within the length of the support frame, and a butterfly bolt is installed on the inner thread of the connecting column, so that the butterfly bolt can be threaded and pressed on one end of the guide rod, so that the guide block can be fixed in the current position.

[0009] Preferably, the mounting mechanism includes a first connecting tube and a second connecting tube, and the first connecting tube and the second connecting tube are respectively fixedly mounted on the inner ends of the two groups of guide blocks, and the first connecting plate and the second connecting plate are respectively slidably mounted in the first connecting tube and the second connecting tube, and the first connecting frame and the second connecting frame are respectively fixedly mounted on the inner ends of the first connecting plate and the second connecting plate.

[0010] Preferably, the first connecting frame and the second connecting frame are staggered and can be slidably inserted into each other, so that a clamping frame groove can be formed between the first connecting frame and the second connecting frame.

[0011] Preferably, connecting grooves are provided in the first connecting plate and the second connecting plate, springs are fixedly connected in the two groups of connecting grooves, and the other ends of the two groups of springs are fixedly connected to one end of the first connecting tube and the second connecting tube respectively.

[0012] Preferably, a pressing plate is fixedly mounted on one end of each of the first connecting plate and the second connecting plate, and both sets of pressing plates slide out from the first connecting tube and the second connecting tube.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the design of the multi-rotor drone body, support frame, guide rod, guide block, connecting column, butterfly bolt and mounting mechanism, when different loads or equipment need to be replaced, the two sets of mounting mechanisms can be pulled to the center for staggered sliding insertion, so that a clamping frame groove can be formed between the two sets of mounting mechanisms, and while pulling toward the center, a resetting elastic pulling force will also be applied to the mounting mechanism until the clamping frame groove formed by the stretching reaches the size required for installation. The load or equipment can then be placed in the clamping frame groove, and then the two sets of mounting mechanisms can be pulled back by the elastic pulling force, so that the load or equipment can be clamped between the two sets of mounting mechanisms, and The process only requires pulling the installation mechanism toward the center, thereby realizing the function of convenient disassembly and installation of the load or equipment. Then, the staff can unscrew the butterfly bolt from the connecting column of the guide block to release the limiting force applied to the guide block. Then, the staff can push the two sets of installation mechanisms to slide vertically in the guide rod through the guide blocks on both sides. After sliding to the appropriate height position, the butterfly bolt can be tightened to make the butterfly bolt thread press against one end of the guide rod to fix the guide block in the current position, thereby driving the load or equipment clamped between the two sets of installation mechanisms to the adjusted height position;

[0015] The staggered sliding and elastic tension design allows for easy removal and installation of loads or equipment, eliminating the need for tedious tool manipulation. Simply pulling the two mounting mechanisms toward the center allows for quick clamping and securing of the load, greatly improving load replacement efficiency. This is particularly suitable for scenarios where different loads need to be frequently replaced.

[0016] The elastic tension of the mounting mechanism ensures that the load will not loosen or fall off during the clamping process, providing a natural pullback force to stabilize the load and avoiding instability problems that may be caused by manual operation. This method ensures that the load can be firmly fixed in the clamping frame slot, improving safety.

[0017] 2. Through the design of the first connecting tube, the second connecting tube, the first connecting plate, the second connecting plate, the first connecting frame and the second connecting frame, when different loads or equipment need to be replaced, the staff can pinch one end of the pressing plate at one end of the first connecting plate and the second connecting plate, thereby driving the first connecting plate and the second connecting plate to slide toward the center in the first connecting tube and the second connecting tube, and the first connecting plate and the second connecting plate will be pulled together on one end of the spring during the process of sliding toward the center in the first connecting tube and the second connecting tube, so that the spring can apply an elastic pulling force to the first connecting plate and the second connecting plate, and the first connecting plate and the second connecting plate slide toward the center. During the process, the first connecting frame and the second connecting frame will be driven to slide into each other in an interlaced manner, thereby enabling a rectangular clamping frame groove to be formed between the first connecting frame and the second connecting frame for filling the load or equipment. When the clamping frame groove formed by stretching reaches the required size for installation, the load or equipment can be placed in the clamping frame groove, and then the first connecting frame and the second connecting frame can be pressed against both sides of the load or equipment by the elastic tension exerted by the spring, thereby completing the clamping of the load or equipment between the first connecting frame and the second connecting frame. When disassembly is required, it is only necessary to enlarge the clamping frame groove formed between the first connecting frame and the second connecting frame.

[0018] The device operates the first connecting plate and the second connecting plate through a pressing plate. The staff only needs to squeeze the pressing plate to quickly drive the first connecting frame and the second connecting frame to slide alternately, forming a clamping frame groove and fixing the load or equipment. When disassembling, only the clamping frame groove needs to be pinched to remove the load. This simplified operation method makes the load replacement process more intuitive and quick, and is especially suitable for scenarios where frequent load replacement is required. The frame groove is formed by a sliding mechanism. This design allows for rapid adjustment according to the size of different loads or equipment. When the size of the clamping frame groove meets the load requirements, the load can be placed in it and fixed, which allows loads of different sizes to be effectively adapted, thereby improving the flexibility and adaptability of the device.

[0031] The staggered sliding and elastic tension design can easily realize the removal and installation of loads or equipment, eliminating the tedious tool operation. Only by pulling the two sets of mounting mechanisms 2 toward the center can the load be quickly clamped and fixed, greatly improving the efficiency of load replacement, which is particularly suitable for scenarios where different loads are frequently replaced.

[0032] The elastic tension of the installation mechanism 2 can ensure that the load will not loosen or fall off during the clamping process during the installation process, providing a natural pullback force to stabilize the load and avoiding instability problems that may be caused by manual operation. This method ensures that the load can be firmly fixed in the clamping frame groove, thereby improving safety.

[0033] like Figure 4-Figure 6 As shown, the mounting mechanism 2 includes a first connecting tube 201 and a second connecting tube 202, which are respectively fixedly mounted on the inner ends of the two groups of guide blocks 104, and a first connecting plate 205 and a second connecting plate 206 are respectively slidably mounted in the first connecting tube 201 and the second connecting tube 202, and a first connecting frame 203 and a second connecting frame 204 are respectively fixedly mounted on the inner ends of the first connecting plate 205 and the second connecting plate 206.

[0034] The first connecting frame 203 and the second connecting frame 204 are staggered and can be slidably inserted into each other, so that a clamping frame groove can be formed between the first connecting frame 203 and the second connecting frame 204 .

When the clamping frame groove formed by stretching reaches the required size for installation, the load or equipment can be placed in the clamping frame groove, and then the first connecting frame 203 and the second connecting frame 204 can be pressed against both sides of the load or equipment by the elastic tension applied by the spring 208, thereby completing the clamping of the load or equipment between the first connecting frame 203 and the second connecting frame 204. When disassembly is required, it is only necessary to enlarge the clamping frame groove formed between the first connecting frame 203 and the second connecting frame 204.

[0039] The working steps of this solution are summarized and sorted out according to the above technical solution: when different loads or equipment need to be replaced, the staff can pinch one end of the pressing plate 209 at one end of the first connecting plate 205 and the second connecting plate 206, thereby driving the first connecting plate 205 and the second connecting plate 206 to slide toward the center in the first connecting tube 201 and the second connecting tube 202, and the first connecting plate 205 and the second connecting plate 206 will be pulled together on one end of the spring 208 during the process of sliding toward the center in the first connecting tube 201 and the second connecting tube 202, so that the spring 208 can apply an elastic pulling force to the first connecting plate 205 and the second connecting plate 206, and the first connecting plate 205 and the second connecting plate 206 slide toward the center. During the process, the first connecting frame 203 and the second connecting frame 204 will be driven to slide into each other in an interlaced manner, so that a rectangular clamping frame groove can be formed between the first connecting frame 203 and the second connecting frame 204 for filling the load or equipment. After the clamping frame groove formed by stretching reaches the required size for installation, the load or equipment can be placed in this clamping frame groove. Subsequently, the first connecting frame 203 and the second connecting frame 204 can be pressed against both sides of the load or equipment through the elastic tension applied by the spring 208, thereby completing the clamping of the load or equipment between the first connecting frame 203 and the second connecting frame 204.
