[0041] In the related art, vehicles such as flying cars are mainly composed of a flight structure and a running structure. In order to ensure the overall firmness of the vehicle, the flight structure and the running structure of the car are usually designed in an integrated manner. At present, existing flying cars are mainly composed of a flight structure and a running structure. In order to improve the overall firmness of the vehicle, the flight structure and the running structure are usually designed in an integrated manner. As for the running structure, it includes structural components with larger mass such as the vehicle chassis. Therefore, the running structure of a flying car using such a design is usually bulky. When the flying car needs to fly in the air, it is difficult to carry a heavier running structure for long-distance flight due to the limitations of the current power system of the flying car and its own load-bearing capacity, which affects the endurance of the flying car. Therefore, it is difficult to further promote its application.

[0042] In view of this, the present application provides a split land-air amphibious vehicle, including a stacked flight unit 100, a carrier unit 200 and a traveling unit 300, wherein the carrier unit 200 can be automatically combined and separated with the traveling unit 300 through a docking structure 400, wherein the docking structure 400 includes a connecting rod 410, a support seat 420, an electromagnetic guide component 430 and a hook 440; the connecting rod 410 is arranged at the bottom of the carrier unit 200, the support seat 420 is arranged in the traveling unit 300, the electromagnetic guide component 430 is arranged on the support seat 420, and is rotatably connected to the hook 440, and the hook 440 is slidably connected to the support seat 420 through a guide column 441, which is used to adjust the movement trajectory of the hook 440 to lock or unlock the connecting rod 410.

[0043] like Figure 1-Figure 11 As shown, the present application provides a split land and air amphibious vehicle, which includes a flight unit 100, a transport unit 200 and a travel unit 300. The flight unit 100 can drive the vehicle to fly in the air, the transport unit 200 can provide a driving position for the driver, and the travel unit 300 can drive the vehicle to travel on the road, so that the vehicle can be used for both land and air; wherein the transport unit 200 and the travel unit 300 are connected by a docking structure 400, and the docking structure 400 can realize automatic combination or separation between the transport unit 200 and the travel unit 300 to ensure the firmness of the connection between the two and the safety of the equipment operation; wherein, before the vehicle flies, the transport unit 200 can be separated from the travel unit 300 and the travel unit 300 can be unloaded to reduce the weight of the vehicle during the flight and extend the flight distance of the vehicle.

[0044] In this embodiment, the travel unit 300 and the carrier unit 200 can be connected by using the docking structure 400 to improve the firmness of the connection between the two, so that the driver can control the combination and separation of the travel unit 300 and the carrier unit 200; wherein the docking structure 400 includes a connecting rod 410, a support seat 420, an electromagnetic guide component 430 and a hook 440, wherein the connecting rod 410 is arranged at the bottom of the carrier unit 200, the support seat 420 is arranged on the travel unit 300, the electromagnetic guide component 430 is slidably arranged on the support seat 420, and the hook 440 is rotatably connected to the electromagnetic guide component 430; when the travel unit 300 and the carrier unit 200 are connected by using the docking structure 400, the connecting rod 410 It can extend from the bottom of the carrier unit 200 and rest on the electromagnetic guide component 430, and use the hook 440 to be clamped on the connecting rod 410 to complete the connection between the carrier unit 200 and the traveling unit 300; when the carrier unit 200 and the traveling unit 300 in the vehicle are separated, the electromagnetic guide component 430 can drive the hook 440 to slide on the support seat 420, so that the hook 440 is disengaged from the connecting rod 410, releases its clamping effect on the connecting rod 410, and restores the connecting rod 410 to its original position. At this time, the flight unit 100 is controlled to drive the carrier unit 200 to rise, so as to separate the carrier unit 200 and the traveling unit 300, so as to reduce the carrying burden of the vehicle during the flight process and extend its flight distance.

[0045] It should be noted that in this application, Figure 1 As shown, the flight unit 100 can adopt a coaxial twin-rotor structure, which can improve the flight efficiency of the vehicle during flight; at the same time, a tail-thrust propeller is provided at the tail end of the flight unit 100, which can provide thrust to the vehicle during flight, which will not be repeated here.

[0046] In some embodiments, the electromagnetic guide component 430 includes a reset spring 431, a guide slider 432, a locking rod 433, a first electromagnetic device 434 and a second electromagnetic device 435; the two ends of the reset spring 431 are respectively connected to the support seat 420 and the guide slider 432, the guide slider 432 is slidably connected to the support seat 420, and the guide slider 432 is provided with a labyrinth slide 4321, one end of the locking rod 433 is rotatably connected to the support seat 420, and the other end is slidably arranged in the labyrinth slide 4321, the first electromagnetic device 434 is arranged on the guide slider 432, and is located below the connecting rod 410, and the second electromagnetic device 435 is arranged on the support seat 420, and is located below the guide slider 432.

[0047] like Figure 2 and Figure 3As shown, in the present embodiment, the moving electromagnetic guide component 430 can drive the hook 440 to slide on the support seat 420, so as to lock or unlock the connecting rod 410 through the hook 440; specifically, when the connecting rod 410 is locked, the carrier unit 200 is placed on the top of the travel unit 300, the first electromagnetic device 434 is turned on and made to have strong magnetism, and the strong magnetism of the first electromagnetic device 434 is used to attract the connecting rod 410, so that the connecting rod 410 extends and rests on the guide slider 432; the second electromagnetic device 435 is turned on and made to have strong magnetism, and the strong magnetism of the second electromagnetic device 435 is used to attract the guide slider 432 to slide downward along the support seat 420, and at the same time, the reset spring 431 is extended, and at this time, one end of the locking pull rod 433 rotatably connected to the support seat 420 is released on the support seat 420. The guide slider 432 is deflected, and the other end slides unidirectionally along the inside of the labyrinth slide 4321 until it is engaged in the labyrinth slide 4321. As the guide slider 432 continues to move downward, the hook 440 connected with its rotation gradually deflects to the side close to the connecting rod 410 on the guide slider 432, and is engaged with the connecting rod 410, that is, the connecting rod 410, the hook 440, the guide slider 432, the locking rod 433 and the support seat 420 are mutually engaged, completing the automatic docking of the travel unit 300 and the carrier unit 200; it should be noted that, in order to reduce energy waste, after the travel unit 300 and the carrier unit 200 are connected, the first electromagnetic device 434 and the second electromagnetic device 435 can be disconnected to make the strong magnetism between the two lose, which will not affect the firmness of the docking structure 400 in connecting the travel unit 300 and the carrier unit 200.

[0048] Similarly, when the locking function of the connecting rod 410 is released, the second electromagnetic device 435 is turned on and generates a strong magnetism, and the strong magnetism is used to attract the guide slider 432 to slide further down the support seat 420. At this time, the other end of the locking rod 433 continues to slide in the labyrinth slide 4321. When the locking rod 433 moves out of the clamping position of the labyrinth slide 4321, the second electromagnetic device 435 is disconnected, so that the guide slider 432 loses the strong magnetic attraction; since the reset spring 431 is in a stretched state, the reset spring 431 is used to The elastic restoring force of the reset spring 431 itself drives the guide slider 432 to slide upward along the support seat 420, and pushes the hook 440 and the connecting rod 410 to move synchronously. At this time, the hook 440 continuously slides upward along the support seat 420 through the guide column 441, and gradually disengages from the connecting rod 410, releasing the clamping effect on it, allowing the connecting rod 410 to return to its original position, thereby realizing automatic unlocking of the docking structure 400 and reducing the difficulty of separating the traveling unit 300 and the carrying unit 200.

[0049] In some embodiments, the maze slide 4321 includes an overlapping portion 4321a, a transition portion 4321b, a locking portion 4321c and an unlocking portion 4321d, the overlapping portion 4321a is respectively connected to the inlet end of the transition portion 4321b and the outlet end of the unlocking portion 4321d, and the two ends of the locking portion 4321c are respectively connected to the outlet end of the transition portion 4321b and the inlet end of the unlocking portion 4321d, and are bent toward the overlapping portion 4321a; wherein a first limiting shoulder 4321e is provided between the overlapping portion 4321a and the outlet end of the unlocking portion 4321d to limit the locking rod 433, and a second limiting shoulder 4321f is provided in the locking portion 4321c to limit the locking rod 433 from falling back to the transition portion 4321b.

[0050] like Figure 2-Figure 5 As shown, when the guide slider 432 slides on the support seat 420, it can drive one end of the locking rod 433 to slide unidirectionally along the labyrinth slide 4321, wherein the labyrinth slide 4321 includes a overlapping portion 4321a, a transition portion 4321b, a locking portion 4321c and an unlocking portion 4321d in sequence, and the unlocking portion 4321d is connected to the overlapping portion 4321a; when the travel unit 300 and the carrier unit 200 are connected by the docking structure 400, the end of the locking rod 433 will sequentially slide along the overlapping portion 4321a and the transition portion 4321b. 1b enters into the locking portion 4321c, and uses the locking portion 4321c bent toward the overlapping portion 4321a, and under the action of the elastic force of the return spring 431, the locking rod 433 and the guide slider 432 are clamped together; when the docking structure 400 is unlocked, the end of the locking rod 433 will successively enter into the overlapping portion 4321a along the locking portion 4321c and the unlocking portion 4321d. At this time, after the guide slider 432 loses the clamping effect of the locking rod 433, it slides upward under the action of the return spring 431 and returns to its original position.

[0051] In addition, a first limiting shoulder 4321e is provided between the outlet ends of the overlap portion 4321a and the unlocking portion 4321d to limit the locking rod 433, so that the depth of the outlet end of the overlap portion 4321a can be greater than the depth of the inlet end of the unlocking portion 4321d, so that the locking rod 433 will not mistakenly enter the unlocking portion 4321d when sliding from the overlap portion 4321a to the transition portion 4321b, ensuring that the locking rod 433 can slide in one direction; in addition, A second limiting shoulder 4321f is provided between the outlet end of the transition portion 4321b and the inlet end of the locking portion 4321c, so that the depth of the outlet end of the transition portion 4321b can be smaller than the inlet end of the locking portion 4321c, so that after the end of the locking rod 433 enters the locking portion 4321c, the moving locking rod 433 will not fall back into the transition portion 4321b, thereby ensuring that the end of the locking rod 433 can move unidirectionally in the transition portion 4321b.

[0052] In some embodiments, a guide groove 4322 is provided on the side of the guide slider 432, and the guide column 441 is slidably arranged inside the guide groove 4322; the guide groove 4322 includes a sliding portion 4322a and a deflection portion 4322b that are connected to each other, and the extension direction of the sliding portion 4322a is the same as the sliding direction of the guide slider 432, and the deflection portion 4322b is tilted away from the guide slider 432, so as to adjust the movement trajectory of the hook 440.

[0053] like Figure 6 As shown, a guide groove 4322 is provided on the side of the guide slider 432, and a guide column 441 connected to the hook 440 slides in the guide groove 4322, so that the movement trajectory of the hook 440 is adjusted by the guide column 441, so as to realize the locking and unlocking of the connecting rod 410; wherein, when the guide slider 432 slides downward, it can drive the hook 440 connected with it to move synchronously, and make the guide column 441 slide from the deflection part 4322b to the sliding part 4322a, so that the hook 440 gradually approaches the connecting rod 410. and is engaged with it; when the slider slides upward, the hook 440 can also move synchronously with the guide slider 432. At this time, the guide column 441 slides from the sliding portion 4322a to the deflection portion 4322b. As the guide slider 432 continues to move, the guide column 441 will drive the hook 440 to gradually disengage from the connecting rod 410 and gradually deflect it away from the connecting rod 410, thereby releasing the locking effect of the hook 440 on the connecting rod 410, and will not affect the connection rod 410 from escaping from the travel unit 300.

[0054] In some embodiments, a positioning hole 520 is provided on the top of the travel unit 300, the guide slider 432 is located below the positioning hole 520, a positioning protrusion 510 adapted to the positioning hole 520 is provided on the bottom of the carrier unit 200, a receiving cavity is provided on the positioning protrusion 510, and the connecting rod 410 is disposed in the receiving cavity; wherein, Figure 2 and Figure 7 As shown, by setting a positioning hole 520 on the top of the traveling unit 300 and setting a positioning protrusion 510 that is compatible with the positioning hole 520 structure on the bottom of the carrying unit 200, it is convenient to position the carrying unit 200 and the traveling unit 300 during the docking process, avoid misalignment when the two are docked, and improve the positioning accuracy.

[0055] In some embodiments, the connecting rod 410 includes a compression spring 411, a locking rod 412 and a slot 413; the compression spring 411 is located in the accommodating cavity, and its two ends are respectively connected to the bottom edge of the accommodating cavity and the top edge of the locking rod 412, the slot 413 is opened on the locking rod 412 and is adapted to the structure of the hook 440, and the bottom of the locking rod 412 and the top of the guide slider 432 are both provided with an inclined section 412a for positioning.

[0056] like Figure 2 , Figure 3 and Figure 7 As shown, the travel unit 300 and the carrier unit 200 can be connected by the docking structure 400, so as to improve the firmness of the connection between the two and realize the automatic combination and separation of the two. In this embodiment, the connecting rod 410 includes a compression spring 411, a locking rod 412 and a card slot 413. When the travel unit 300 and the carrier unit 200 are locked by the docking structure 400, the locking rod 412 can move from the storage cavity toward the side close to the electromagnetic guide component 430 under the influence of the strong magnetism generated by the first electromagnetic device 434 in the electromagnetic guide component 430, and at the same time, the compression spring 411 is pressed. Pressure is applied to make the locking rod 412 rest against the guiding slider 432, and the guiding slider 432 will drive the hook 440 to engage in the slot 413 on the locking rod 412, thereby realizing the connection between the connecting rod 410 and the electromagnetic guide component 430; and when the docking structure 400 is unlocked, the hook 440 is gradually disengaged from the slot 413 driven by the guiding slider 432, and the engagement with the locking rod 412 is released. At this time, the elastic force of the compression spring 411 itself is used to drive the locking rod 412 to move toward the side away from the traveling unit 300, so that the locking rod 412 returns to the inside of the storage cavity.

[0057] In some embodiments, a position identifier (not marked in the figure) is provided on the top of the traveling unit 300, and a visual recognition device (not marked in the figure) is provided on the bottom of the carrier unit 200 for identifying the installation position of the carrier unit 200 on the traveling unit 300; in this embodiment, the carrier unit 200 can be transported to the traveling unit 300 by the flying unit 100, thereby reducing the labor burden of the staff; wherein, a visual recognition device is provided on the bottom of the carrier unit 200, and when the carrier unit 200 and the traveling unit 300 are spliced, the visual recognition device is used according to the installation position of the traveling unit 300.
