[0035] Please refer to Figures 1-8 The utility model provides a technical scheme a big load unmanned plane transport device, including integral type EVA protection seat 1, tray metal plate component 2 and pressure buckle locking assembly 3;

[0036] Integral type EVA protection seat 1 and pressure buckle locking assembly 3 are installed on tray metal plate component 2 respectively;

[0037] After completing the transportation, when the unmanned plane needs to be disassembled, only the unmanned plane motor is pushed out of the integral type EVA protection seat 1, and the handles of the pressure buckle locking assembly 3 on the four corners are pushed away in reverse, the unmanned plane device on the tray can be quickly taken out, greatly improving the convenience.

[0038] The tray metal plate component 2 includes a square tube framework 201, an aluminum alloy skin 202, a handle 203, a boss 204, and a universal wheel 205. The square tube framework 201 has a square grid structure and is spaced apart (see Figure 3 The aluminum alloy skin 202 is welded to the top of the square framework (see Figure 2 The boss 204 has four numbers and is welded to the upper and lower four corners of the aluminum alloy skin 202. The handle 203 has four numbers and is welded to the middle position of the edge line of the square tube framework 201.

[0039] The wheels 205 are fixed to the lower bosses 204 by nuts respectively;

[0040] The handles 203 are distributed around the edges of the tray metal assembly 2, which can effectively assist in the process of transfer under the conditions of steps, uneven road surfaces, etc.

[0041] The pressure buckle locking assembly comprises a base 301, a first crescent piece 302, a second crescent piece 303, a handle 304, a cross bridge piece 305, a long shaft 306, a short shaft 307, a silica gel pad 308, and a silica gel strip 309.

[0042] The base 301 is locked on the bosses 204 on the upper surface of the tray metal assembly 2 by nuts, and a groove is formed in the middle after the base 301 is combined with the bosses 204. The silica gel pad 308 is adhered to the groove by anaerobic epoxy resin glue, and the four edges are fitted with the base 301 and coated with glue.

[0043] Preferably, the silica gel pad 308 is fixed in position by limiting around and anaerobic epoxy resin glue, which ensures that it will not be delaminated, displaced, or torn when bearing a large force, and avoids hard contact between the unmanned aerial vehicle foot support and the tray metal assembly 2 due to the elastic properties of silica gel, reducing vibration transmission and wear.

[0044] The first crescent piece 302 and the second crescent piece 303 are connected to the left protruding structure of the base 301 by the short shaft 307, and the crescent pieces are prevented from falling off by screwing into the short shaft. Since there is a gap between the first crescent piece 302 and the second crescent piece 303 and the protruding structure, the crescent pieces can move freely.

[0045] The short shaft 307 passes through the first crescent piece 302, the handle 304, and the second crescent piece 303 in sequence and is locked by a nut. There is a gap between the first crescent piece 302, the second crescent piece 303, and the handle 304, which ensures that the handle can rotate freely relative to the first crescent piece 302, the second crescent piece 303, and the short shaft 307. The long shaft 306 passes through the shaft hole of the other protruding structure on the base 301 in sequence, the shaft hole of the cross bridge piece 305, and a screw, which is locked. There is a gap between the cross bridge piece 305 and the protruding structure of the base 301, which ensures that the cross bridge piece 305 can rotate freely relative to the base 301 around the long shaft 306. The silica gel strip 309 is adhered to the downward concave surface of the cross bridge piece 305 by anaerobic epoxy resin glue.

[0046] The cross bridge piece 305 is designed with grooves at both ends of the upper and lower concave surfaces, and the silica gel strip 309 is embedded in the grooves. The two ends are adhered by anaerobic glue, and the middle segment is bent due to the squeezing force from both ends to the middle and adheres to the cross bridge piece. This design ensures that the silica gel piece will not crack or delaminate due to the squeezing stress during use.

[0047] Preferably, a silica gel strip 309 is arranged between the cross bridge 305 and the contact surface of the foot stand, which avoids direct contact and abrasion between the foot stand and the metal part when locked. The silica gel elasticity ensures that the carbon fiber round pipe foot stand will not be damaged by impact loads such as vibration and bumping during transportation.

[0048] Working principle: The design of the buckle locking assembly 3 utilizes the principle of a lever. When the cross bridge 305 is pressed upward by the foot stand, it tends to rotate upward around the long axis 306, which acts on one end of the handle 304, as shown in Figure 6 The center of rotation of the handle 304 at this time is located inside the action point of the cross bridge 305 and the handle 304, thereby generating a self-locking tendency, which ensures that the buckle locking assembly 3 will not open by itself due to vibration and bumping during transportation, thereby ensuring that the position of the foot stand remains unchanged during transportation. When it is necessary to open the buckle locking assembly 3, only a reverse force needs to be applied to the handle 304 by hand, which can be rotated to open, thereby achieving the requirement of quick disassembly.

[0049] When assembling, conversely, the handle 304 and the cross bridge 305 are first opened to their respective sides, the unmanned aerial vehicle foot stand is placed on the silica gel pad 308, the cross bridge 305 is first rotated to cover the foot stand, and the handle 304 and the first and second crescent pieces 302 and 303 are turned over, as shown in Figure 7 When the cam end of the handle 304 hits the cross bridge 305, the crescent piece stops at this time, and the handle 304 rotates downward around the contact point as the fulcrum, which can automatically unlock.

[0050] The length of the arc segment of the cross bridge 305 is selected to be about 3 pipe diameters of the foot stand. This design takes into account that the foot stand is likely to deform greatly during use. The arc length of 3 pipe diameters of the foot stand ensures that the buckle locking assembly 3 can be normally locked and used when the foot stand deforms to a certain extent, and at the same time, the left and right movement space is not too large to cause the overall foot stand to move to both sides.

[0051] The integrated EVA protective seat 1 is designed with two grooves on each of the four sides, which are shaped and sized to fit the unmanned aerial vehicle motor and the folded blades. Square avoidance areas are designed on the four corners to avoid interference with the working state of the buckle locking assembly 3, and grooves are designed on the four sides.

[0052] Preferably, the handle 203 is attached to the grooves on the four sides of the integrated EVA protective seat 1, which ensures that the EVA protective seat will not be displaced or misaligned on the tray.

[0053] The unmanned aerial vehicle foot stand is limited in position by the grooves on both sides of the integrated EVA protective seat 1, and the bent pipe is locked on the four corners by the buckle locking assembly 3, which limits the overall position of the machine frame.

[0054] In summary, the integral EVA protection seat 1, the buckle locking assembly 3 and the handle 203 form double limiting protection for the unmanned aerial vehicle, greatly improving the safety and reliability of transportation.

[0055] The specific embodiments of the utility model have been described in detail above, but it is only as an example, the utility model is not limited to the specific embodiments described above. Any equivalent modification or alternative to the utility model for those skilled in the art is also within the scope of the utility model, therefore, equivalent transformation and modification, improvement, etc. made without departing from the spirit and principle range of the utility model should be covered in the scope of the utility model.
