Description

Technical Field

[0001] This utility model belongs to the field of aircraft technology, and in particular relates to a heavy-load launcher for eVTOL aircraft. Background Technology

[0002] In emergency situations such as natural disaster relief and military operations, eVTOL aircraft can quickly reach the scene thanks to their vertical takeoff and landing and flexible flight characteristics. They can then deliver supplies to designated locations via a dropper, greatly improving efficiency compared to traditional transportation methods. In some dangerous scenarios, such as fire scenes and war zones, using eVTOL aircraft to drop supplies can avoid direct involvement of ground personnel, reducing the risk of casualties. Furthermore, eVTOL aircraft themselves have the advantage of not requiring a runway and being able to take off and land in confined spaces. When equipped with a dropper, they can easily deliver supplies to target locations in mountainous areas, swamps, isolated islands, and other places with inconvenient transportation or sparse population, solving problems that are difficult to overcome by traditional transportation methods.

[0003] When using an eVTOL aircraft to drop objects, traditional dropping methods often fail to ensure that the dropped objects accurately reach the designated location. The lack of effective positioning and cushioning mechanisms in the past has resulted in low dropping accuracy and easy damage to objects. Secondly, after fixing the dropping device to the bottom of the aircraft, it is not convenient to drop objects in an orderly and convenient manner. Traditional structures are difficult to release objects quickly, affecting dropping efficiency. Furthermore, after a drop is completed, it is not convenient to prepare for the next drop, as the process of resetting and reinstalling traditional devices is cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a large-payload thrower for eVTOL aircraft, which solves the problems of traditional throwing methods that make it difficult to ensure that the thrown object accurately reaches the designated position. In the past, there was a lack of effective positioning and buffering methods, which resulted in low throwing accuracy and easy damage to the object. Secondly, after the throwing device is fixed to the bottom of the aircraft, it is not convenient to throw the object in an orderly and convenient manner. Traditional structures are difficult to release the object quickly, which affects the throwing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a heavy-load launcher for an eVTOL aircraft, including a frame, on which a launching mechanism and a hoisting mechanism are provided; The throwing mechanism includes three connecting blocks fixedly connected to the top of the frame. An electric push rod is fixedly connected to the inner wall of each of the three connecting blocks. A baffle is fixedly connected to the output end of each of the three electric push rods. Two grooves are opened on each of the three connecting blocks. A limit block is rotatably connected to the inner wall of each of the two grooves. The top surface of the baffle contacts the bottom surface of each of the two limit blocks.

[0006] Furthermore, the inner walls of both grooves are rotatably connected to hinge block one, and the two limiting blocks are rotatably connected to hinge block two.

[0007] Furthermore, springs are fixedly connected between the two hinge blocks one and the two hinge blocks two, and both springs are in a stretched state.

[0008] Furthermore, the hoisting mechanism includes limiting grooves respectively formed on the bottom surface of the connecting block and the top surface of the limiting block, the limiting grooves being semi-circular.

[0009] Furthermore, a retaining ring is provided between the two limiting grooves, and a sling is fixedly connected to the outer wall of the retaining ring.

[0010] Furthermore, a balance ring is fixedly connected to one end of the sling's principle retaining ring, and two balance rings are fixedly connected to the balance ring, with two fixing posts fixedly connected to each of the two balance rings.

[0011] Furthermore, the top of the frame is provided with three throwing objects, and the top of each of the three throwing objects is fixedly connected with four lifting lugs. Each of the four lifting lugs is fixedly connected with a lifting rope, and the end of each of the four lifting ropes away from the lifting lugs is fixedly connected to the outer wall of several fixed columns.

[0012] Furthermore, four fixed frames are fixedly connected to the top of the frame, and the four fixed frames are fixed to the bottom of the eVTOL aircraft by a number of bolts.

[0013] This utility model has the following beneficial effects: 1. The device is equipped with a throwing mechanism. The thrown objects consist of a parachute and a throwing chamber. After the objects are thrown, the parachute opens and throws the throwing chamber to the designated location. After the entire device is fixed to the bottom of the eVTOL aircraft by a fixing frame and bolts, when it is necessary to throw objects, the electric push rod can be driven to move the baffle, so that the two retaining rings slide out of the limiting groove under the action of gravity. At this time, the two retaining rings are disengaged from the limiting groove, and then three objects are thrown. After the throwing is completed, the multiple limiting blocks rebound and fit against the bottom surface of the connecting block under the reset action of the first hinge block, the second hinge block and the spring, which facilitates the next installation and throwing, and greatly improves the convenience of the overall device.

[0014] 2. With a hoisting mechanism, after the balance ring is fixed to the shackle by the slings, multiple limit blocks are fixed to the fixed column and the lifting lugs respectively. After the drone lifts and throws the object, due to the large weight of the object and the uneven weight, the balance ring tilts at different angles, so that the multiple slings are taut during hoisting, preventing the slings from loosening and ensuring that the multiple slings are evenly stressed. This prevents the object from overturning due to uneven stress on the multiple slings during throwing and transportation, and improves the stability during throwing and transportation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] Please see Figure 1-5 As shown, this utility model is a heavy-load launcher for eVTOL aircraft, including a frame 1, on which a launching mechanism 2 and a hoisting mechanism 3 are provided; The throwing mechanism 2 includes three connecting blocks 21 fixedly connected to the top of the frame 1. Electric push rods 22 are fixedly connected to the inner walls of each of the three connecting blocks 21. Baffles 23 are fixedly connected to the output ends of each of the three electric push rods 22. Two grooves 24 are formed on each of the three connecting blocks 21. Limit blocks 26 are rotatably connected to the inner walls of each of the two grooves 24. The top surface of the baffle 23 contacts the bottom surface of each of the two limit blocks 26. Hinge blocks 1 25 are rotatably connected to the inner walls of each of the two grooves 24. Hinge blocks 27 are rotatably connected to each of the two limit blocks 26. The two hinge blocks 1 25 and the two hinge blocks 27... Springs 28 are fixedly connected between 7, and both springs 28 are in a stretched state. By setting up a throwing mechanism 2, the electric push rod 22 can be driven to drive the baffle 23, so that the two retaining rings 32 slide out of the limiting groove 31 under the action of gravity. At this time, the two retaining rings 32 are disengaged from the limiting groove 31, and then the three throwing objects 4 are thrown respectively. After the throwing is completed, the multiple limiting blocks 26 rebound and adhere to the bottom surface of the connecting block 21 under the reset action of the first hinge block 25, the second hinge block 27 and the springs 28, which facilitates the next installation and throwing, and greatly improves the convenience of the overall device.

[0021] The hoisting mechanism 3 includes limiting grooves 31 respectively formed on the bottom surface of the connecting block 21 and the top surface of the limiting block 26. The limiting grooves 31 are semi-circular. A retaining ring 32 is provided between the two limiting grooves 31. A sling 33 is fixedly connected to the outer wall of the retaining ring 32. A balance ring 34 is fixedly connected to one end of the sling 33 away from the retaining ring 32. Two balance rings 34 are fixedly connected to the balance rings 34. Two fixing posts 35 are fixedly connected to each of the two balance rings 34. Three throwing objects 4 are provided on the top of the frame 1. Four lifting lugs 37 are fixedly connected to the top of each of the three throwing objects 4. Lifting ropes 36 are fixedly connected to each of the four lifting lugs 37. The four lifting ropes 36 are positioned away from the lifting lugs 37. One end of the frame is fixedly connected to the outer wall of several fixed columns 35. Four fixed frames 11 are fixedly connected to the top of the frame 1. The four fixed frames 11 are fixed to the bottom of the eVTOL aircraft by several bolts 12. With the hoisting mechanism 3, after the UAV lifts and throws the object 4, due to the large weight of the object 4 and the uneven weight, the balance ring 34 is tilted at different angles, so that the multiple hoisting ropes 36 are taut during hoisting, preventing the hoisting ropes 36 from becoming loose, ensuring that the multiple hoisting ropes 36 can be evenly stressed, preventing the object 4 from overturning due to uneven stress on the multiple hoisting ropes 36 during throwing and transportation, and improving the stability during throwing and transportation.

[0022] A specific application of this embodiment is as follows: By setting up a throwing mechanism 2, the thrown object 4 is composed of a parachute and a throwing bin. After the thrown object 4 is thrown, the parachute opens and throws the throwing bin to the designated position. After the whole device is fixed to the bottom of the eVTOL aircraft by the fixing frame 11 and bolts 12, when it is necessary to throw the thrown object 4, the electric push rod 22 can be driven to drive the baffle 23, so that the two retaining rings 32 slide out of the limiting groove 31 under the action of gravity. At this time, the two retaining rings 32 are disengaged from the limiting groove 31, and then the three thrown objects 4 are thrown respectively. After the throwing is completed, the multiple limiting blocks 26 rebound and adhere to the bottom surface of the connecting block 21 under the reset action of the hinge block 1 25, hinge block 27 and spring 28, which facilitates the next installation and throwing, and greatly improves the convenience of the whole device. With the hoisting mechanism 3 in place, after the balancing ring 34 is fixed to the shackle 32 by the sling 33, multiple limit blocks 26 are fixed to the fixing column 35 and the lifting lug 37 respectively. After the drone lifts and throws the object 4, due to the large weight of the object 4 and the uneven weight, the balancing ring 34 tilts at different angles, so that the multiple slings 36 are taut during hoisting, preventing the slings 36 from becoming loose, ensuring that the multiple slings 36 can be evenly stressed, and preventing the object 4 from overturning due to uneven stress on the multiple slings 36 during throwing and transportation, thus improving the stability during throwing and transportation.
