Description

Technical Field

[0001] This utility model relates to the field of aluminum frame structure technology, specifically to an aluminum load-bearing frame assembly structure. Background Technology

[0002] Heavy-payload drones refer to unmanned aerial vehicles with large payload capacity, which are typically used in transportation, logistics, agriculture, industry or military fields. The skeleton of a heavy-payload drone is its core structural component, which is made of aluminum and needs to have characteristics such as high strength, lightweight and corrosion resistance to support heavy-load tasks.

[0003] As the core load-bearing structure of heavy-duty UAVs, aluminum load-bearing frames replace traditional steel frames. The existing aluminum load-bearing frame gantry mainly consists of a pair of U-shaped frames, and the connection between the U-shaped frames is usually assembled and spliced ​​by a single U-shaped connecting clamp. However, its assembly structure is relatively simple, resulting in low overall structural stability of the frame, which affects the load-bearing performance. Therefore, an aluminum load-bearing frame assembly structure is proposed. Utility Model Content

[0029] Please see Figures 1-4 This utility model provides an embodiment of an aluminum load-bearing frame assembly structure:

[0030] An aluminum load-bearing frame assembly structure, comprising:

[0031] The first frame 1 and the second frame 2 are detached and connected by the disassembly and assembly assembly 3;

[0032] The disassembly and assembly component 3 includes a lock groove 301, a lock block 302, a fastening bolt 303, a stop block 304, a slide rod 305, a spring 306, a pad block 307, a rotating part 308, and a screw hole 309;

[0033] Lock groove 301 is formed on the surface of the first frame 1, lock block 302 is formed on one side of the second frame 2, stop block 304 is detachably connected to the first frame 1, slide rod 305 is slidably connected to the first frame 1, spring 306 is sleeved on the outside of slide rod 305, pad block 307 is fixedly connected to the end of slide rod 305, rotating part 308 is rotatably connected to pad block 307, fastening bolt 303 is set on one side of rotating part 308, and screw hole 309 is formed on the side of the surface of the first frame 1 away from lock groove 301;

[0034] The two ends of the spring 306 are fixedly connected to the first frame 1 and the pad 307 respectively, and the retractable spring 306 is used to assist the pad 307 in moving. The above structural design allows the hand to press the pad 307, causing the pad 307 to squeeze the slide rod 305 and the spring 306, and the spring 306 to be compressed.

[0035] The lock groove 301 is used for the lock block 302 to be inserted into it. The above structural design allows the first frame 1 and the second frame 2 to be aligned so that the second frame 2 can insert the lock block 302 into the lock groove 301.

[0036] The locking groove 301 and locking block 302 in the engaged state are used to pre-connect the first frame 1 and the second frame 2. The above structural design allows the second frame 2 to insert the locking block 302 into the locking groove 301, so the locking groove 301 and locking block 302 in the engaged state pre-connect the first frame 1 and the second frame 2.

[0037] In one preferred embodiment, the screw hole 309 is used for threaded connection of the fastening bolt 303. The above structural design allows the fastening bolt 303 to be inserted into the screw hole 309 and rotated.

[0038] In one preferred embodiment, the tightened fastening bolt 303 is used to assemble the first frame 1 and the second frame 2. The above structural design allows the fastening bolt 303 to be threadedly connected to the screw hole 309, so the tightened fastening bolt 303 assembles the first frame 1 and the second frame 2.

[0039] In one preferred embodiment, the surface of the stop 304 is formed with a groove for inserting the slide rod 305 and the spring 306. The above structural design allows the stop 304 to be placed horizontally on the surface of the first frame 1, and the slide rod 305 and the spring 306 to be inserted into the groove of the stop 304.

[0040] In one preferred embodiment, the pad 307, which is in a state of moving closer to the first frame 1, is used to press the stop 304. The above structural design makes the pad 307, which is in a state of moving closer to the first frame 1, move to a position that contacts the surface of the stop 304, and the stop 304 presses the stop 304.

[0041] In one preferred embodiment, the pressurized stop 304 is used to press the lock block 302. The above structural design makes the stop 304 press the lock block 302.

[0042] The working principle of this utility model is as follows: When it is necessary to assemble the first frame 1 and the second frame 2, firstly, align the first frame 1 and the second frame 2 so that the second frame 2 inserts the locking block 302 into the locking groove 301. Then, the locking groove 301 and the locking block 302 in the engaged state pre-connect the first frame 1 and the second frame 2. At this time, place the stop block 304 horizontally on the surface of the first frame 1, and insert the slide rod 305 and the spring 306 into the groove of the stop block 304. Press the pad block 307 with your hand so that the pad block 307 squeezes the slide rod 305 and the spring 306. The spring 306 is compressed by force, and then moves closer to the first frame 1. When the pad 307 in the moving state of the frame 1 moves to a position that contacts the surface of the stop 304, and the stop 304 presses against the stop 304, the pressed stop 304 presses against the locking block 302. Then, the fastening bolt 303 is inserted into the screw hole 309 and rotated to make the fastening bolt 303 threadedly connected to the screw hole 309. The tightened fastening bolt 303 assembles the first frame 1 and the second frame 2. Thus, the above structure facilitates the disassembly and installation of the first frame 1 and the second frame 2, and effectively improves the stability of the assembly of the first frame 1 and the second frame 2.
