[0040] like Figure 1 and Figure 2 As shown, a passenger-cargo convertible aircraft of this embodiment includes a cabin 1 and a floor 11 horizontally installed in the cabin 1. The floor 11 divides the cabin 1 into a passenger space 12 and a first cargo space 13 arranged vertically. It also includes multiple cargo pallets 2 and multiple seats 3 installed on the floor 11.

[0041] like Figure 3As shown, the seat 3 comprises a base 31, a backrest 32, a lifting mechanism 33 and an adjusting mechanism 34, the base 31 is installed on the floor 11 through the lifting mechanism 33, that is, the fixed end of the lifting mechanism 33 is vertically installed on the floor 11, and the lifting end of the lifting mechanism 33 is connected with the base 31. The backrest 32 is located above the base 31, and an included angle is provided between the center line of the backrest 32 and the center line of the base 31. The adjusting mechanism 34 is located on the same side of the base 31 and the backrest 32, and is connected with the same side side wall of the base 31 and the backrest 32 respectively, for adjusting the included angle. The backrest 32 can be adjusted to be folded in half and tend to be parallel with the base 31 through the adjusting mechanism 34, and the plurality of cargo plates 2 can be detachably connected with the back side of the backrest 32 which tends to be parallel, so as to convert the passenger space 12 into the second cargo space 14. By arranging the adjusting mechanism 34, the included angle between the base 31 and the backrest 32 can be adjusted, so as to fold the backrest 32 in half with the base 31 and tend to be parallel, and the cargo plate 2 is detachably installed on the back side of the backrest 32, so as to convert the passenger space 12 into the second cargo space 14, which facilitates placing goods on the plurality of cargo plates 2, realizes the conversion without disassembling the seat 3, greatly reduces the time and cost of passenger-cargo conversion, and reduces the risk of structural damage caused by frequent disassembly, so that the aircraft can provide more passenger seats in the tourist peak season, and meet the passenger transport demand. In the non-tourist season or e-commerce shopping festival and other cargo transportation peak period, it can be quickly converted into a cargo transportation mode, improve the applicability and versatility of the aircraft, and improve the resource utilization rate. Or the passenger has more goods, and the goods and passengers are transported together, realizing the maximum utilization of the pickup truck aircraft.

[0042] As Figure 4 and Figure 5As shown, the adjusting mechanism 34 comprises a mounting plate 341, a gear ring 342, a clamping plate 343 and an adjusting plate 344. The mounting plate 341 is fixedly installed on one side wall of the backrest 32, the bottom of the mounting plate 341 is rotatably installed on the side wall of the base 31 through a first fixing shaft, the bottom of the mounting plate 341 is in a circular structure, and the inner ring of the gear ring 342 is connected with the outer wall of the circular structure. The bottom of the clamping plate 343 is rotatably installed on the side wall of the base 31 through a second fixing shaft, the clamping plate 343 is located below the mounting plate 341, and the side wall of the clamping plate 343 facing the gear ring 342 can be engaged with the gear ring 342 to engage the clamping plate 343 with the gear ring 342, thereby fixing the included angle, so that reliable fixation between the backrest 32 and the base 31 at any angle can be achieved, the stability between the backrest 32 and the seat 3 is improved, the stability and impact resistance are improved, and the safety of the passenger in the passenger mode is ensured. An adjusting rod 345 is arranged on the side wall close to the top of the clamping plate 343, one end of the adjusting plate 344 is rotatably sleeved on the first fixing shaft, the other end is an adjusting end, a through slot 3441 is arranged on the adjusting plate 344, and the adjusting rod 345 is inserted into the through slot 3441. When the angle between the backrest 32 and the base 31 needs to be adjusted, the adjusting plate 344 is pressed downward to drive the clamping plate 343 to rotate around the axis of the second fixing shaft through the adjusting rod 345, so that the clamping plate 343 is disengaged from the gear ring 342, and the included angle is adjusted. By arranging the mounting plate 341, the gear ring 342, the clamping plate 343 and the adjusting plate 344, the included angle between the backrest 32 and the base 31 can be quickly adjusted. Only the adjusting plate 344 needs to be pressed downward, and the clamping plate 343 can be driven to rotate around the second fixing shaft through the adjusting rod 345 to disengage from the gear ring 342, so that the angle of the backrest 32 can be easily adjusted. The backrest 32 can be bent to a horizontal state close to the base 31, avoiding complex tools or additional operation steps, and significantly improving the convenience and efficiency of operation.

[0043] A rope joint can be arranged between the backrest (32) and the base (31). In the flat state, the backrest (32) is bound by the rope joint, which further prevents the backrest (32) from rebounding.

[0044] As shown in the figure, Figure 5 The through slot 3441 is vertically V-shaped and presents an obtuse angle. The through slot 3441 is in sliding connection with the adjusting rod 345 to provide movement space and guidance for the adjusting rod 345. The through slot 3441 can effectively guide the movement track of the adjusting rod 345, so that when the adjusting plate 344 is pressed downward, the adjusting rod 345 can smoothly slide along the inclined surface of the through slot 3441, thereby providing clear movement space and guidance for the adjusting rod 345, avoiding deviation or jamming during the adjusting process, and improving the overall stability of the adjusting mechanism 34.

[0045] As shown in the figure, Figure 4As shown, the adjusting mechanism 34 further comprises a coil spring 346. The mounting plate 341 is provided with a mounting rod 348 on the side wall away from the backrest 32. The coil spring 346 is wound around the outer wall of the first fixed shaft, with one end connected to the first fixed shaft and the other end connected to the mounting rod 348. When the adjusting plate 344 is released, the coil spring 346 can automatically drive the clamping plate 343 back to re-engage with the gear ring 342, achieving quick clamping and improving the reliability of the clamping between the backrest 32 and the base 31.

[0046] As shown in Figure 4 , the adjusting mechanism 34 further comprises a limiting rod 347. The limiting rod 347 is installed on the side wall of the base 31 facing the mounting plate 341 and is located below the first fixed shaft to provide limiting for the clamping plate 343, ensuring that the clamping plate 343 does not rotate excessively during adjustment, avoiding instability or damage caused by excessive movement of the clamping plate 343.

[0047] As shown in Figure 6 , the adjusting mechanism 34 further comprises a housing to seal the various components in the adjusting mechanism 34, preventing injury caused by accidental touch by passengers.

[0048] As shown in Figure 7 , the present embodiment further comprises a locking mechanism 4. The back side wall of the backrest 32 is provided with a guide groove 5, and the bottom of the cargo plate 2 is provided with a protrusion 6. The cargo plate 2 is installed on the back side of the backrest 32 through the protrusion 6 and the guide groove 5 to provide guidance for the installation of the cargo plate 2. The locking mechanism 4 is vertically installed on the cargo plate 2. The bottom inner wall of the guide groove 5 is provided with a clamping groove 51, and the bottom of the locking mechanism 4 can be placed in the clamping groove 51 through the bottom wall of the cargo plate 2 to lock the cargo plate 2 in the guide groove 5. By setting the locking mechanism 4, the cargo plate 2 can be firmly locked on the back side of the backrest 32, ensuring the stability and reliability of the cargo plate 2 in the cargo transport mode, avoiding displacement or falling caused by bumps or vibrations during flight, thereby improving the safety of cargo transport.

[0049] As shown in Figure 8 , the locking mechanism 4 comprises a pull rod 41 and a pull ring 42. The pull ring 42 is installed on the top of the pull rod 41, and the bottom of the pull rod 41 passes through the cargo plate 2 and can be placed in the clamping groove 51 to lock the cargo plate 2. By setting the pull ring 42 and the pull rod 41, quick locking and unlocking can be achieved. Simply pull the pull rod 41 and insert the bottom of the pull rod 41 directly into the clamping groove 51 to complete the locking, and pull the pull rod 41 upwards to unlock. This can quickly achieve the installation and disassembly of the cargo plate 2 without the need for additional tools or complex steps, improving the disassembly efficiency of the cargo plate 2. At the same time, it can effectively prevent the cargo plate 2 from loosening or falling off due to bumps or vibrations during flight, thereby improving the safety and stability in the cargo transport mode.

[0050] When the seat 3 is flat, a small gap exists between the cargo board 2 and the seat 3. A wooden board or other material can be inserted into the gap to increase the support of the cargo board 2.

[0051] As shown in Figure 8 The locking mechanism 4 further includes a resilient member 43 and a fixed plate 44. The cargo board 2 is provided with a displacement space 21, the pull rod 41 passes through the displacement space 21, and the resilient member 43 and the fixed plate 44 are located in the displacement space 21. The fixed plate 44 and the resilient member 43 are sleeved on the outer wall of the pull rod 41, and the fixed plate 44 is fixedly connected with the pull rod 41. One end of the resilient member 43 is connected with the top wall of the displacement space 21, and the other end is connected with the fixed plate 44. The resilient member 43 (such as a spring) provides a resilient force for the fixed plate 44 and the pull rod 41, ensuring that the bottom of the pull rod 41 is firmly inserted into the clamping groove 51, avoiding loosening caused by vibration or external force, and significantly improving the reliability of the locking mechanism 4. In particular, when the plane encounters turbulence during flight, the locking mechanism 4 can effectively prevent the cargo board 2 from falling off.

[0052] As shown in Figure 6 The lifting mechanism 33 includes a plurality of air cylinders 331. The fixed ends of the plurality of air cylinders 331 are connected with the floor 11, and the telescopic ends of the plurality of air cylinders 331 are connected with the bottom of the base 31. By arranging the plurality of air cylinders 331, the height of the base 31 can be adjusted, so that the seat 3 can adapt to different scenes, such as providing a more comfortable sitting height for passengers in passenger mode, or adjusting the height of the base 31 to facilitate the installation of the cargo board 2 and the carrying of goods in cargo mode. Generally, when the cargo board 2 is installed, the lifting mechanism 33 is lowered to the lowest position to ensure consistency.

[0053] Preferably, the lifting mechanism 33 can also be a single air cylinder 331, which adjusts the lifting of the lifting end of the air cylinder 331 by a lifting rod, such as a swivel chair, which will not be described here.

[0054] As shown in Figure 2 The plurality of seats 3 are arranged in a rectangular array on the floor 11, and the adjacent two cargo boards 2 on the same row of seats 3 are attached. This can make the cargo boards 2 have no gap, avoiding the goods falling from the gap. The adjacent two cargo boards 2 on the same column of seats 3 are connected by the groove 22 and the protrusion 23, which improves the connection stability between the adjacent two cargo boards 2. Moreover, the plurality of cargo boards 2 form a whole through their own gravity, which not only fully utilizes the space between the seats 3 without occupying more space, but also increases the weight, thereby avoiding the backrest 32 from being popped up due to the rebounding effect of the coil spring 346, and improving the stability of the cargo mode.

[0055] Based on the above structure, the working principle of a passenger-cargo convertible aircraft in this embodiment is as follows:

[0056] like Figure 1 As shown, when the seat 3 is in passenger mode and needs to be switched to freight mode, simply press down on the adjustment plate 344 to make the adjustment rod 345 drive the locking plate 343 to rotate around the axis of the second fixed shaft, so that the locking plate 343 disengages from the gear ring 342. Then, the backrest 32 is folded down to fold against the base 31 until the included angle approaches 0°. At this time, the limiting rod 347 limits the locking plate 343. Then, the cargo plate 2 is installed on the back side of the backrest 32 through the guide groove 5. When the pull rod 41 is about to enter the slot 51, the elastic member 43 applies a rebound force to the fixed plate 44, causing the bottom of the pull rod 41 to lock into the slot 51. At the same time, the elastic member 43 can also continuously apply a rebound force to the fixed plate 44, which is equivalent to pressure, making the pull rod 41 and the slot 51 more stably locked. The cargo trays 2 on adjacent seats 3 in the same row engage with the grooves 22 on the already installed cargo trays 2 via protrusions 23, achieving locking and guidance. The locking mechanism 4 is installed using the locking method described above, which will not be elaborated further here. In this way, each cargo tray 2 is installed sequentially, completing the conversion between the passenger space 12 and the second cargo space 14.

[0057] When it is necessary to convert the second cargo space 14 into the passenger space 12, simply pull the pull ring 42 to disengage the pull rod 41 from the slot 51, compress the elastic element 43, and remove the cargo plate 2. Then, the backrest 32 will spring back due to the action of the coil spring 346 until the engaging plate 343 engages with the toothed ring 342. Finally, according to the passenger's own needs, the angle between the backrest 32 and the base 31 can be changed by moving the adjustment plate 344 to disengage the engaging plate 343 from the toothed ring 342, allowing the passenger to lean back against the backrest 32 to achieve a comfortable position. Then, the adjustment plate 344 can be released to allow the engaging plate 343 to engage with the toothed ring 342 again, completing the engagement at the desired angle. The angles of other seats 3 are adjusted in the same way as described above, and will not be repeated here.

[0058] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

One skilled in the art should understand that the above embodiments can be modified or equivalent replacements can be made to some technical features without departing from the scope and spirit of the present application. In particular, the technical features mentioned in each embodiment can be combined in any manner as long as there is no structural conflict.
