[0067] Fifth, the vertical height of the connecting device of the split flying car of the embodiment of the utility model is small, which is conducive to reducing the driving center of gravity and flight resistance. Through the setting of the guide wheel-guide groove mechanism, the z-direction height, that is, the vertical height, of the first matching part 1 and the second matching part 2 after matching is greatly reduced, so that the flight module I and the cabin II are almost attached to each other after being combined, and the gap between the two is very small, which reduces the overall center of gravity of the flight module I and the cabin II, increases stability, reduces the windward area during the flight process, and reduces the flight resistance; through the setting of the guide wheel-guide rail mechanism, the z-direction height, that is, the vertical height, of the third matching part 3 and the fourth matching part 4 after matching is greatly reduced, so that the cabin II and the chassis III are almost attached to each other after being combined, and the gap between the two is very small, which reduces the overall center of gravity of the cabin II and the chassis III, increases stability, and reduces driving resistance.

[0068] Sixth, the first matching part 1 and the second matching part 2 are small in size, light in weight, and simple in structure, which is beneficial to improving the load-bearing capacity of the flight module I and the cabin II.

The first driving assembly 233 is used to drive the first locking movable latch 232 to rotate between a low position and a high position.

[0080] When the plug-in block 2311 is inserted into the slot 121 from the front notch 1211, the first driving assembly 233 drives the first locking snap 232 to a high position, so that the first locking snap 232 abuts against the rear end of the card seat 12, for example, abuts against the rear end of the bottom plate 123 of the card seat 12, so that the first locking snap 232 and the plug-in block 2311 are locked around the lower end of the card seat 12, that is, the bottom plate 123 of the card seat 12 is locked around by the first locking snap 232 and the plug-in block 2311. It should be noted that during the docking process between the flight module I and the cabin II, the short arm 111 cooperates with the front load-bearing beam 21, and the plug-in block 2311 cooperates with the slot 121.

[0081] When the embracing latch locking mechanism needs to be unlocked, the first locking latch 232 is driven to a low position by the first driving assembly 233 to realize the unlocking function. At this time, the chassis III carries the cabin II forward to separate the cabin II from the flight module I.

[0082] In some embodiments, the third matching portion 3 includes a front docking wheel set 31, a rear docking wheel set 32, and a second latch mechanism 33. There are two front docking wheel sets 31 and they are symmetrically distributed at the bottom front of the cabin II, and there are two rear docking wheel sets 32 and they are symmetrically distributed at the bottom rear of the cabin II. The symmetry axes of the two front docking wheel sets 31 coincide with the symmetry axes of the two rear docking wheel sets 32. The spacing between the two front docking wheel sets 31 is smaller than the spacing between the two rear docking wheel sets 32. The front docking wheel sets 31 and the rear docking wheel sets 32 play the role of guiding and constraining docking and bearing weight; the second latch mechanism 33 is arranged at the bottom rear of the cabin II and is located between the two rear docking wheel sets 32. The second latch mechanism 33 plays the role of locking after docking.

[0083] The fourth matching part 4 includes a guide rail assembly 41 and an error compensation mechanism 42. There are two guide rail assemblies 41, which are symmetrically distributed. The distance between the front ends of the two guide rail assemblies 41 is smaller than the distance between the rear ends of the two guide rail assemblies 41. The guide rail assembly 41 provides a sliding channel for the corresponding front docking wheel assembly 31 and the rear docking wheel assembly 32, plays a role in guiding and constraining the docking direction, facilitates docking, and also plays a role in connecting and bearing the cabin II and the chassis III; there are two error compensation mechanisms 42, and the two error compensation mechanisms 42 are respectively connected between the front ends of the two guide rail assemblies 41 and between the rear ends of the two guide rail assemblies 41; the error compensation mechanism 42 plays a role in error compensation and load-bearing during the docking process between the cabin II and the chassis III and the docking process between the flight module I and the chassis III. Among them, the front docking wheel assembly 31 and the rear docking wheel assembly 32 form a guide wheel-guide rail mechanism with the guide rail assembly 41. The second latch mechanism 33 and the error compensation mechanism 42 located between the rear ends of the two guide rail assemblies 41 form a stop locking mechanism.

[0084] Thus, through the cooperation of the front docking wheel group 31, the rear docking wheel group 32 and the guide rail assembly 41, on the one hand, the docking and separation process between the cabin II and the chassis III is smooth and natural, with little vibration and impact, and on the other hand, the z-direction height after the cooperation of the third matching part 3 and the fourth matching part 4, that is, the vertical height, can be greatly reduced, so that the cabin II and the chassis III can be almost attached to each other after being combined, and the gap between the two is very small, which reduces the overall center of gravity of the cabin II and the chassis III, increases stability, and reduces driving resistance. The lateral error, angle error and height error caused by insufficient control accuracy during the docking process between the flight module I and the cabin II and the cabin II and the chassis III can be compensated by the error compensation mechanism 42. The reliable connection between the cabin II and the chassis III is achieved through the guide wheel-guide rail mechanism, the stop locking mechanism and the error compensation mechanism 42, and the structural strength is high, safe and reliable.

[0085] In some embodiments, the front docking wheel group 31 includes a front mounting base 311, a front load-bearing wheel 312 and a front guide wheel 313. The front mounting base 311 is fixed to the bottom front part of the cabin II, and the front load-bearing wheel 312 and the front guide wheel 313 are arranged on the front mounting base 311. The front load-bearing wheel 312 plays a load-bearing role, and the front guide wheel 313 plays a guiding and restraining role. The rear docking wheel group 32 includes a rear mounting base 321, a rear load-bearing wheel 322 and a rear guide wheel 323. The rear load-bearing wheel 322 plays a load-bearing role, and the rear guide wheel 323 plays a guiding and restraining role. The rear mounting base 321 is fixed to the bottom rear part of the cabin II, and the rear load-bearing wheel 322 and the rear guide wheel 323 are arranged on the rear mounting base 321.

[0086] The guide rail assembly 41 includes a guide rail 411 with a guide groove, a front locking box 412 fixed to the front end of the guide rail 411, and a rear locking box 413 fixed to the rear end of the guide rail 411, wherein the guide groove of the guide rail 411 is used to adapt to the corresponding front guide wheel 313 and rear guide wheel 323 to play a guiding and restraining role, and the front locking box 412 and the rear locking box 413 are used to lock the corresponding front load-bearing wheel 312 and rear load-bearing wheel 322 to connect and bear the load on the cabin II and the chassis III.

[0087] In some embodiments, the error compensation mechanism 42 includes a mounting base 421, a universal ball 422 and a sliding beam 423; the mounting base 421 is fixed to the bottom of the cabin II; the sliding beam 423 passes through the mounting base 421 and the two ends of the sliding beam 423 are fixed to the two guide rails 411, that is, the two sliding beams 423 and the two guide rails 411 form a fixed approximately rectangular structure; the universal ball 422 has a plurality of heavy universal balls 422 and is arranged between the sliding beam 423 and the mounting base 421, and the plurality of universal balls 422 are distributed on the front side, the rear side, the upper side and the lower side of the beam. Thus, the plurality of heavy universal balls 422 can change the relative position of the sliding beam 423 inside the mounting base 421.

[0088] In some embodiments, the second latch mechanism 33 includes a second drive assembly 331 and a second locking latch 332. The second drive assembly 331 is fixed to the bottom of the cabin II. The second drive assembly 331 is hinged with the second locking latch 332 to drive the second locking latch 332 to rotate between a low position and a high position. After the front load-bearing wheel 312 enters the corresponding front locking box 412 and the rear load-bearing wheel 322 enters the corresponding rear locking box 413, the second drive assembly 331 drives the second locking latch 332 to rotate from a high position to a low position, so that the second locking latch 332 abuts against the rear side of the mounting base 421 of the error compensation mechanism 42 located between the rear ends of the two guide rail assemblies 41.

[0089] When cabin II and chassis III are connected, the installation base 421 flight module I locks cabin II and docks on the ground to wait, and the chassis III backs up from the front of the flight module I to start docking. At this time, the second locking latch 332 is in a high position. Since the distance between the front ends of the two guide rails 411 is smaller than the distance between the rear ends and the distance between the two front docking wheels is smaller than the distance between the two rear docking wheels, the two front docking wheels are not in contact with the two guide rails 411 at the beginning. As the chassis III continues to move backward, the two front docking wheels begin to contact with the two guide rails 411 and constrain each other to guide and correct the docking direction; when there is a lateral, angular or height error, the guide rail 411 will be subjected to the force of the front guide wheel 313, and this force is transmitted to the two sliding beams 423 of the two error compensation structures through the guide rail 411. With the assistance of a number of universal balls 422, the sliding beam 423 moves horizontally and slightly inside the installation base 421. The angle is rotated or the height is changed, so that the two guide rails 411 change direction or height to adapt to the cabin II installed with the third matching part 3; when the front load-bearing wheels 312 of the two front docking wheels enter the two front locking boxes 412 respectively, the rear load-bearing wheels 322 of the two rear docking wheels enter the two rear locking boxes 413 respectively, and then the second driving component 331 drives the second locking latch 332 to rotate to a low position, so that the front end of the second locking latch 332 abuts against the rear side of the mounting base 421 of the error compensation structure located between the rear ends of the two guide rails 411, so as to lock the cabin II on the chassis III, thereby completing the docking process of the cabin II and the chassis III.

[0090] It should be noted that during the docking process between the flight module I and the cabin II, the second locking latch 332 is in a high position. When there is a lateral, angular or height error, the guide rail 411 will be subjected to the force of the front guide wheel 313, and the force is transmitted to the two sliding beams 423 of the two error compensation structures through the guide rail 411. With the assistance of several universal balls 422, the sliding beams 423 translate, rotate at a small angle or change in height inside the mounting base 421, thereby causing the two guide rails 411 to change direction or height to adapt to the flight module I installed with the first mating part 1.

[0091] In some embodiments, the second driving assembly 331 is installed on the bottom rear cross beam of the cabin II, and the bottom rear cross beam of the cabin II has sufficient structural strength.
