Description

Technical Field

[0001] This utility model relates to the field of heavy-duty unmanned aerial vehicle (UAV) technology, specifically to a quick-fixing device for the load plate of a heavy-duty UAV. Background Technology

[0002] Heavy-duty drones are drones capable of carrying heavy loads. Generally, their load capacity ranges from tens of kilograms to several tons. They can be used in various industries to perform tasks such as transportation, delivery, and operations. The load plate is a key component for heavy-duty drones to carry cargo. The load plate needs to withstand the weight of the cargo and various external forces during flight. Before use, it needs to be fixedly installed on the frame using a fixing device.

[0003] Currently, when using load-bearing plate fixing devices, a quick-assembly and disassembly mechanism is lacking. Typically, the load-bearing plate needs to be fixed to the frame at the bottom of the drone using bolts and other fasteners. To ensure the stability of the load-bearing plate during operation, multiple fasteners are required, resulting in limited convenience and flexibility in actual assembly and disassembly. Therefore, a quick-assembly fixing device for the load-bearing plate of a drone is proposed to add a quick-assembly and disassembly mechanism. Utilizing plug-in, positioning, and reinforcement methods, a dual fixing structure is formed simultaneously, which improves the convenience and flexibility of assembly and disassembly operations, reduces the number of fasteners used, and enhances the stability of the load-bearing plate connection, thereby improving the overall performance.

[0007] By adopting the above technical solution and adding a quick assembly / disassembly mechanism, a double-fixed structure is formed simultaneously through plugging, positioning, and reinforcement, which can improve the convenience of assembly / disassembly operations.

[0008] Specifically, slide rails are provided on both sides of the load-bearing plate, and double threaded rods are installed in the slide rails via bearings. Corresponding ball sliders are sleeved around the double threaded rods, and the ball sliders are connected to the mounting base by bolts.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To facilitate the use of plug-in, positioning, and reinforcement methods, thereby improving the convenience and flexibility of assembly and disassembly operations and enhancing the overall performance, such as... Figure 1-3 As shown, the present invention provides a quick fixing device for a load-bearing drone load plate, comprising a load plate 1, a fixing component 3, and a driving component 4. Mounting seats 2 are slidably connected to both sides of the top of the load plate 1. The fixing component 3 is fixedly disposed on the outer side of the mounting seat 2. The driving component 4 is disposed at the top and bottom of the fixing component 3.

[0026] The fixing component 3 includes a fixing frame 301, and the mounting base 2 is connected to the fixing frame 301 by bolts. A limiting block 302 is welded to the other side of the fixing frame 301. A U-shaped sleeve 303 is sleeved around the limiting block 302, and the U-shaped sleeve 303 is inserted into and connected to the fixing frame 301. A reinforcing plate 304 is slidably connected to both the top and bottom of the limiting block 302 on the other side of the fixing frame 301.

[0027] In use, a quick disassembly and assembly mechanism is added through mounting base 2, fixing bracket 301, limiting block 302, U-shaped sleeve 303, and reinforcing plate 304. By using plug-in, positioning, and reinforcement methods, a double fixing structure is formed at the same time, which improves the convenience of disassembly and assembly operations.

[0028] The fixing bracket 301, the limiting block 302, the U-shaped sleeve 303, and the reinforcing plate 304 are all made of aluminum alloy.

[0029] To improve the flexibility of use, for example, such as Figure 1 , Figure 3 As shown, the present invention also includes slide rails 101 on both sides of the load plate 1, a double threaded rod 102 installed in the slide rail 101 by bearings, a corresponding ball block slider 103 sleeved around the double threaded rod 102, and the ball block slider 103 connected to the mounting base 2 by bolts.

[0030] In use, the slide rail 101, double threaded rod 102, and ball block slider 103 can be used to add an auxiliary adjustment mechanism to adjust the position and range of the fixing device according to the actual length of the crossbar of the drone frame.

[0031] For example, such as Figure 2 As shown, the present invention also includes a card block 305 on the surface of the reinforcing plate 304, a slot 306 corresponding to the U-shaped sleeve 303 in the fixing frame 301, and positioning holes 307 corresponding to the card block 305 on the surfaces of the U-shaped sleeve 303 and the limiting block 302.

[0032] In use, the card block 305, slot 306 and positioning hole 307 can be used to fix and reinforce the U-shaped sleeve 303 and the reinforcing plate 304. The reinforcing plate 304 is welded to the card block 305.

[0033] For example, such as Figure 3 As shown, the present invention also includes a rotating rod 104 provided on the surface of the load-bearing plate 1, and one end of the rotating rod 104 is connected to a double threaded rod 102 by bolts.

[0034] In use, the rotating rod 104 facilitates the rotation of the double threaded rod 102 for adjustment.

[0035] For example, such as Figure 4 , 5 As shown, the present invention also includes a positioning rod 5 provided on the top of the fixing frame 301, a protrusion 501 welded on both sides of the positioning rod 5, and a threaded section 502 provided at one end of the positioning rod 5.

[0036] In use, the positioning rod 5, the protruding strip 501 and the threaded section 502 can be used to complete the quick fixing operation by means of plug-in limit and threaded connection.

[0037] For example, such as Figure 5As shown, the present invention also includes a drive assembly 4 including a lead screw 401, and the top and bottom of the fixing frame 301 are both mounted on the lead screw 401 by bearings. A corresponding second ball block 402 is sleeved around the lead screw 401. A channel 403 is opened in the lead screw 401, and grooves 404 corresponding to the protrusions 501 are opened on both sides of the channel 403.

[0038] During use, the lead screw 401, the second ball slider 402, the channel 403 and the groove 404 facilitate the rotation and reinforcement of the positioning rod 5. Operators can perform regular maintenance by applying lubricating oil to the surfaces of the double threaded rod 102 and the lead screw 401.

[0039] For example, such as Figure 2 , 4 As shown, the present invention also includes a through hole 308 on the surface of the U-shaped sleeve 303 corresponding to the positioning rod 5, and a fixing cap 309 corresponding to the positioning rod 5 is provided at the bottom of the fixing bracket 301.

[0040] In use, the through hole 308 allows the positioning rod 5 to pass through the U-shaped sleeve 303 while also providing a limiting and reinforcing treatment. The fixing cap 309 facilitates the connection of the threaded section 502 via a thread. The fixing cap 309 includes an anti-loosening washer.

[0041] When using this utility model, the operator first places the load plate 1 between the bottom frames of the load-bearing drone. According to the actual length of the frame crossbar, the operator manually rotates the rotating rod 104 to drive the double threaded rod 102 to rotate. The ball slider 103 drives the mounting base 2 to slide relative to each other, which can adjust the position and spacing of the fixing components 3 to adapt to load-bearing drones of different sizes and improve the flexibility and adaptability of use.

[0042] Next, insert the U-shaped sleeve 303 into the fixed frame 301 from the outside of the frame crossbar, so that the end can be inserted into the corresponding slot 306. Then, insert the positioning rod 5 from the top of the fixed frame 301, and pass through the channel 403 and through hole 307 of the lead screw 401 in sequence. Then, rotate the positioning rod 5. At the same time, the fixed frame 301 and the fixed cap 309 are connected by the threaded section 502. The convex strip 501 drives the groove 404 and the lead screw 401 to rotate. The second ball slider 402 can simultaneously drive the reinforcing plate 304 to slide relative to the top and bottom of the U-shaped sleeve 303, so that the clamping block 305 of the reinforcing plate 304 is inserted into the corresponding positioning hole 307, and the U-shaped sleeve 303 is clamped and reinforced. The overall structure is simple and compact, the operation is more convenient and quick, and it can also play an auxiliary reinforcement role, improving the stability and safety of the load plate 1.
