[0030] Embodiments

[0031] As Figures 1-4As shown, this utility model provides a cabin weight loading device 1 for loading a weight 2 onto a weight mounting beam 3. The cabin weight-adding device 1 specifically includes a lifting mechanism 11 and a slide rail 12. The slide rail 12 is detachably installed on the cabin floor 4. The lifting mechanism 11 includes a lifting screw 111, a lifting fixing seat 112, a sliding block 113, and a pulley 114. The lifting fixing seat 112 is a columnar structure with an open bottom and a hollow interior. The sliding block 113 is installed inside the lifting fixing seat 112. The sliding block 113 is a solid metal block. A groove 115 is opened on the lifting fixing seat 112, and a limiting pin 116 passes through the groove 115 and is fixed to the sliding block 113. The lifting screw 111 is installed on the top of the lifting fixing seat 112. The lifting fixing seat 112 is moved longitudinally by adjusting the lifting screw 111. The pulley 114 is installed at the bottom of the sliding block 113. The pulley 114 cooperates with the slide rail 12 to realize the lateral movement of the lifting mechanism 11.

[0032] Slide grooves 115 are formed oppositely on the lifting fixed base 112 along the moving direction of the slide rail 12. Preferably, two sets of slide grooves 115 are formed oppositely on the lifting fixed base 112 along the moving direction of the slide rail 12. A limiting pin 116 is installed in each of the two sets of opposite slide grooves 115. The limiting pin 116 passes through the lifting fixed base 112 and extends to the outside of the lifting fixed base 112. By setting the limiting pin 116, the lateral and directional displacement of the sliding block 113 can be restricted. When the lifting fixed base 112 moves longitudinally, the slide grooves 115 also move longitudinally. The slide grooves 115 and the limiting pins 116 are relatively displaced, thereby the lifting fixed base 112 and the sliding block 113 are also relatively displaced, realizing the lifting and lowering of the lifting fixed base 112.

[0033] When installing the heavy object 2 onto the heavy object mounting beam 3, multiple lifting mechanisms 11 and corresponding slide rails 12 need to be installed. Multiple lifting mechanisms 11 are used to fix the passenger cabin heavy object 2, and the multiple lifting mechanisms 11 slide on the corresponding slide rails 12. For example... Figure 5 In the middle, two lifting mechanisms 11 and a matching slide rail 12 are respectively set on both sides of the passenger cabin heavy object 2. The two sides of the passenger cabin heavy object 2 are fixed to the lifting mechanisms 11 by bolts. The lifting mechanism 11 is adjusted to move the heavy object 2 up and down.

[0034] like Figures 5-7 As shown, the load-bearing beam 3 is fixed to the cockpit floor 4 and close to the rear cockpit frame 5, which is perpendicular to the cockpit floor 4. The cockpit floor 4 is fixed above the cockpit longitudinal beam 6 and is supported by the lower side frame 7 to ensure the flatness and stability of the cockpit floor 4. A reinforcing seat 8 can be optionally installed between the cockpit floor 4 and the load-bearing beam 3 to support the load-bearing beam 3 and ensure its stability.

[0035] The heavy object 2 is arranged below the center of gravity of the aircraft, thereby reducing the influence of the heavy object 2 on the center of gravity of the aircraft, and no additional counterweight is needed. Figure 8 and Figure 9 As shown in the schematic diagram of the layout of the passenger cabin and the center of gravity of the eVTOL aircraft, the passenger cabin of the eVTOL aircraft is located at the front of the fuselage of the aircraft, close to the nose of the aircraft, the front of the passenger cabin is a seat position, and the rear of the passenger cabin is a heavy object 2 installation position.

[0036] The heavy object 2 can be a battery pack, a cargo simulation pack, various test loads, and other objects with large volume and weight.

[0037] As shown in the schematic diagram of the layout of the passenger cabin and the center of gravity of the eVTOL aircraft, the passenger cabin of the eVTOL aircraft is located at the front of the fuselage of the aircraft, close to the nose of the aircraft, the front of the passenger cabin is a seat position, and the rear of the passenger cabin is a heavy object 2 installation position. Figures 10-13 The working principle of the utility model is as follows:

[0038] Adding heavy object: when the heavy object 2 needs to be added to the heavy object mounting beam 3, the lifting fixing seat 112 of the four lifting mechanisms 11 is fixed to the two sides of the heavy object 2 through bolts, the width between the heavy object 2 and the passenger cabin heavy object adding device 1 on the two sides is measured, that is, the width between the two sliding rails 12 to be installed is determined, the two sliding rails 12 are installed on the passenger cabin floor, and the distance between the two sliding rails 12 is the width between the lifting mechanisms 11 on the two sides of the heavy object 2. Adjust the lifting screw 111 on the lifting mechanism 11, so that the bottom surface of the heavy object 2 is higher than the heavy object mounting beam 3, and the heavy object 2 and the heavy object mounting beam 3 are basically parallel, then the lifting mechanism 11 fixed with the heavy object 2 is moved to the position above the heavy object mounting beam 3 along the sliding rail 12, and the mounting hole at the bottom of the heavy object 2 is aligned with the mounting hole on the heavy object mounting beam 3, the heavy object 2 and the heavy object mounting beam 3 are fixed with bolts, and the heavy object 2 installation is completed. After the heavy object 2 is installed, the lifting mechanism 11 and the sliding rail 12 are disassembled, and thus the heavy object 2 is added.

[0039] Similarly, disassembling the heavy object: when the heavy object 2 needs to be disassembled from the heavy object 2 mounting frame, the lifting fixing seat 112 of the four lifting mechanisms 11 is fixed with the heavy object 2 through bolts, and the sliding rail 12 is installed below the lifting mechanism 11 in advance, the lifting mechanism 11 is placed on the sliding rail 12, so that the lifting mechanism 11 can slide along the sliding rail 12, then the fixing screws of the heavy object 2 and the heavy object mounting beam 3 are unscrewed, then the lifting screw 111 is rotated, so that the heavy object 2 rises and separates from the heavy object mounting beam 3; after the heavy object 2 and the heavy object mounting beam 3 are separated, the lifting mechanism 11 is moved along the sliding rail 12, so that the heavy object 2 and the heavy object mounting beam 3 are completely separated, the heavy object 2 can be moved to the trolley or equivalent transportation device again, and the disassembly of the heavy object 2 is realized.
