Abstract

This application discloses a separation and connection mechanism, a land vehicle, and transportation equipment, relating to the field of flying car technology. The separation and connection mechanism includes a telescopic mechanism and a guide structure. The telescopic mechanism can extend relative to the vehicle body of the land vehicle to carry the aircraft. The guide structure has an inclined section and a chute section. The inclined section is located at the end of the guide structure facing the aircraft and is set to be inclined downwards relative to the chute section. The inclined section guides the guide wheel assembly to rise, allowing the aircraft to detach from the telescopic mechanism in the height direction. During the process of the aircraft being pulled into the vehicle body, the telescopic mechanism extends and carries the aircraft. The aircraft can be pulled into the inclined section and, guided by the inclined section, can detach from the telescopic mechanism in the height direction, thereby allowing for fine-tuning of the aircraft's altitude and ensuring that the aircraft can be smoothly pulled into the vehicle body of the land vehicle afterwards.

Description

Technical Field

[0001] This application relates to the field of flying car technology, and in particular to a separation and connection mechanism, a land vehicle, and transportation equipment. Background Technology

[0002] Flying cars have always been a key research area, and with the development of pure electric vertical takeoff and landing aircraft, flying cars have ushered in a new research boom. Flying cars possess both flying and land-based functions, and they come in many forms. One form of flying car decouples the land and flight scenarios. It consists of two parts: a land-based body (also known as a land vehicle) and an aircraft. The land-based body can drive on the road like a car, while the aircraft flies in the sky when needed. At the same time, the land-based body can also be combined with the aircraft to form a complete flying car.

[0003] In existing technology, a traction mechanism is installed inside the vehicle body of a land vehicle to pull the aircraft into the land vehicle, thus facilitating the storage of the aircraft inside the land vehicle. However, during the process of pulling the aircraft into the land vehicle, the aircraft is supported on the ground by support arms and wheels. The height of the aircraft often differs from the height of the inner bottom of the land vehicle body. If the height of the aircraft is not adjusted, it may result in the aircraft being too low to be pulled into the land vehicle body. Utility Model Content

[0004] The main purpose of this application is to propose a separation and connection mechanism, a land vehicle, and a transportation device, which aims to solve the problem that the height of the aircraft and the height of the inner bottom of the land vehicle body often differ. If the height of the aircraft is not adjusted, the aircraft may be too low to be pulled into the land vehicle body.

[0005] To achieve the above objectives, the present application proposes a separation and connection mechanism, which is located in a land vehicle and is used to connect or separate from an aircraft, wherein the land vehicle includes a vehicle body and the aircraft includes a guide wheel assembly.

[0006] The separation and bonding mechanism proposed in this application includes:

[0007] A telescopic mechanism, movably mounted on the body of the land vehicle, and capable of extending outward relative to the vehicle body to carry the aircraft; and

[0008] A guide structure is provided on the body of the land vehicle and located on one side of the telescopic mechanism. The guide structure has an inclined section and a chute section. The inclined section is located at the end of the guide structure facing the aircraft and is configured to be inclined downward relative to the chute section. The inclined section is used to guide the guide wheel assembly to rise so that the aircraft can disengage from the telescopic mechanism in the height direction.

[0009] This application also proposes a land vehicle, including a vehicle body and a separation and engagement mechanism, the separation and engagement mechanism being mounted on the vehicle body.

[0010] This application also proposes a transportation device, including an aircraft and a land vehicle, wherein the body of the land vehicle is used to carry the aircraft.

[0011] The technical solution of this application employs a telescopic mechanism and a guide structure on the separation and connection mechanism. The telescopic mechanism can extend relative to the vehicle body of the land vehicle to carry the aircraft. The guide structure has an inclined section and a chute section. The inclined section is located at the end of the guide structure facing the aircraft and is set to be inclined downward relative to the chute section. The inclined section is used to guide the guide wheel assembly to rise, so that the aircraft can detach from the telescopic mechanism in the height direction. During the process of the aircraft being pulled into the vehicle body of the land vehicle, the telescopic mechanism extends and carries the aircraft. The aircraft can be pulled into the inclined section and, guided by the inclined section, can detach from the telescopic mechanism in the height direction, thereby allowing the height of the aircraft to be finely adjusted, ensuring that the aircraft can be smoothly pulled into the vehicle body of the land vehicle afterwards.

[0033] Reference Figure 1 and Figure 2 In one embodiment of this application, the vehicle includes a land vehicle 1000 and an aircraft 2000. The land vehicle 1000 is used for driving on the ground, and the aircraft 2000 is used for flying in the air after detaching from the land vehicle 1000. The aircraft 2000 and the land vehicle 1000 can be combined and separated. Figure 1 As shown, when the aircraft 2000 is combined with the land vehicle 1000, the land vehicle 1000 can carry the aircraft 2000; when the aircraft 2000 is separated from the land vehicle, the aircraft 2000 can detach from the land vehicle 1000 and fly independently, and the land vehicle 1000 can detach from the aircraft 2000 and drive independently.

[0034] In some implementations, the aircraft 2000 may be an aircraft 2000 powered by conventional energy sources such as fuel, or it may be an aircraft 2000 such as a hybrid electric aircraft 2000, a pure electric aircraft 2000, or a fuel cell electric aircraft 2000.

[0035] In some embodiments, the land vehicle 1000 can be a vehicle powered by conventional energy sources such as gasoline or diesel, or it can be a hybrid electric vehicle, a pure electric vehicle, or a fuel cell electric vehicle. The land vehicle 1000 may have a camouflage compartment on its body, which is suitable for accommodating the aircraft 2000.

[0036] In some embodiments, the land vehicle 1000 is provided with a separation and connection mechanism 1900 for connecting or separating from the aircraft, thereby enabling the land vehicle 1000 to connect or separate from the aircraft 2000.

[0037] Among them, reference Figure 3 The separation and connection mechanism 1900 includes a telescopic mechanism 1300, which is movably mounted on the body 1340 of the land vehicle 1000 and can extend outward relative to the body 1341 of the land vehicle 1000 to carry the aircraft 2000.

[0038] The telescopic mechanism 1300 can extend out of the vehicle body 1340 by sliding, so that a portion of the structure of the telescopic mechanism 1300 can extend outward relative to the vehicle body 1340. Specifically, the telescopic mechanism 1300 is provided with a guide rail, and a slider is installed at the bottom of the telescopic mechanism 1300. The slider slides on the guide rail toward the outside of the vehicle body 1340, so that a portion of the structure of the telescopic mechanism 1300 extends outward from the vehicle body 1340. This portion of the structure of the telescopic mechanism 1300 is used to support the aircraft 2000.

[0039] The telescopic mechanism 1300 can also extend outside the vehicle body 1340 by means of extension. Specifically, the telescopic mechanism 1300 includes multiple telescopic frames, which are movably mounted on the vehicle body 1340 of the land vehicle 1000 and are movably connected to each other. The multiple telescopic frames can extend outward toward the vehicle body 1340 to carry the aircraft 2000.

[0040] Among them, reference Figure 2 The telescopic mechanism 1300 is equipped with a locking mechanism 1001, and the aircraft 2000 is provided with a connecting mechanism 2001. The connecting mechanism 2001 can be locked onto the locking mechanism 1001 to connect the aircraft 2000 to the land vehicle 1000. For example, when the aircraft 2000 needs to be connected to the land vehicle 1000, the locking mechanism 1001 on the telescopic mechanism 1300 can lock the aircraft 2000 and the land vehicle 1000 together through the connecting mechanism 2001. The locking mechanism 1001 is connected to the land vehicle 1000, and the connecting mechanism 2001 is located on the aircraft 2000, which reduces the load added to the aircraft 2000 by the weight of the locking mechanism 1001.

[0041] To facilitate the guidance of the aircraft 2000 into the vehicle body 1340 of the land vehicle 1000, in some embodiments, reference is made to... Figure 5 and Figure 7The aircraft 2000 includes a guide wheel assembly 2004, and the separation and connection mechanism 1900 also includes a guide structure 1310. The guide structure 1310 is located on the body 1340 of the land vehicle 1000 and is located on one side of the telescopic mechanism 1300.

[0042] Specifically, the locking mechanism 1001 locks with the connection mechanism 2001 of the aircraft 2000, and pulls the aircraft 2000 into the rear 1342 of the land vehicle 1000. (Refer to...) Figures 3 to 5 The load-bearing component 1302 of the telescopic mechanism 1300 extends out of the vehicle body 1340 to support the aircraft 2000. At this time, the guide wheel assembly 2004 of the aircraft 2000 is lower than the slide section 1312 of the guide structure 1310. Subsequently, the rear 1342 of the land vehicle 1000 can be raised by the suspension system of the land vehicle 1000, so that the load-bearing component 1302 of the telescopic mechanism 1300 located at the rear 1342 tilts upward, thereby raising the aircraft 2000. After the aircraft 2000 is raised by the land vehicle 1000 and the load-bearing component 1302, the height of the guide wheel assembly 2004 of the aircraft 2000 is increased, and it can then enter the guide structure 1310 of the land vehicle 1000.

[0043] The guide structure 1310 is provided with an inclined section 1311 and a chute section 1312. The inclined section 1311 is located at one end of the guide structure 1310 that faces the aircraft 2000 and is set to be inclined downward relative to the chute section 1312. The inclined section 1311 is used to guide the guide wheel assembly 2004 to rise so that the aircraft 2000 can disengage from the telescopic mechanism 1300 in the height direction.

[0044] Specifically, after the aircraft 2000 is lifted by the land vehicle 1000 and the load-bearing assembly 1302, the guide wheel assembly 2004 of the aircraft 2000 can enter the inclined section 1311.

[0045] Then, the aircraft 2000 can be pulled into the body 1340 of the land vehicle 1000 by a traction mechanism installed on the body 1340 of the land vehicle 1000, and the guide wheel assembly 2004 of the aircraft 2000 can enter the chute section 1312 from the inclined section 1311. Alternatively, it can be pulled into the body 1340 by an extension frame installed on the inner wall of the body 1340 of the land vehicle 1000, and the guide wheel assembly 2004 of the aircraft 2000 can enter the chute section 1312 from the inclined section 1311.

[0046] Reference Figures 6 to 7Because the inclined section 1311 is set to slope downwards relative to the chute section 1312, when the aircraft 2000 is pulled, the guide wheel assembly 2004 of the aircraft 2000 can smoothly slide into the chute section 1312 along the inclined section 1311. The height of the aircraft 2000 is adjusted, thereby allowing the aircraft 2000 to disengage from the telescopic mechanism 1300 in the height direction. This allows the aircraft 2000 to slide within the chute section 1312 and be pulled into the body 1340 of the land vehicle 1000. After the aircraft 2000 is pulled into the body 1340 of the land vehicle 1000, it can be stored inside the body 1340 so that the land vehicle 1000 can transport the aircraft 2000 on the road.

[0047] During the process of the aircraft 2000 being pulled into the body 1340 of the land vehicle 1000, the telescopic mechanism 1300 extends outward and carries the aircraft 2000. The aircraft 2000 can be pulled into the inclined section 1311, and guided by the inclined section 1311, it can detach from the telescopic mechanism 1300 in the height direction, thereby allowing the height of the aircraft 2000 to be finely adjusted, ensuring that the aircraft 2000 can be smoothly pulled into the body 1340 of the land vehicle.

[0048] Optionally, refer to Figure 8 There can be two guide structural members 1310, which are arranged on both sides of the telescopic mechanism 1300. Guide wheel assemblies 2004 are provided on both sides of the aircraft 2000. The guide wheel assemblies 2004 on both sides of the aircraft 2000 slide on the guide structural members 1310 to smoothly slide into the interior of the vehicle body 1340 of the land vehicle 1000. Since the guide wheel assemblies 2004 are prone to wear and tear after long-term use, they can be detachably installed on the aircraft 2000 for easy replacement. For example, the guide wheel assemblies 2004 can be installed on the bottom of the aircraft 2000 with screws.

[0049] In some embodiments, in order for the telescopic mechanism 1300 to extend beyond the exterior of the vehicle body 1340 of the land vehicle 1000, refer to Figure 9 The telescopic mechanism 1300 includes a sliding component 1301 and a load-bearing component 1302. The sliding component 1301 is disposed on the load-bearing component 1302 and is movably connected to the vehicle body 1340. Part of the structure of the load-bearing component 1302 is used to extend outward from the vehicle body 1340 and carry the aircraft 2000.

[0050] The sliding component 1301 can be a pulley. Multiple pulleys can be provided, positioned on both sides of the supporting component 1302. These pulleys can slide outwards from the vehicle body 1340 of the land vehicle 1000, thereby extending the supporting component 1302 outwards from the vehicle body 1340. Furthermore, the supporting component 1302 can be a plate-like structure to support the aircraft 2000.

[0051] The sliding component 1301 may also include a guide rail and a slider. The guide rail is disposed within the body 1340 of the land vehicle 1000, and the slider is disposed at the bottom of the support component 1302. The slider slides on the guide rail toward the outside of the body 1340, thereby driving the support component 1302 to move toward the outside of the body 1340. Optionally, there may be two sliders. The two sliders may be disposed at the bottom of the support component 1302, and the two sliders may be disposed on both sides of the support component 1302, so as to smoothly drive the support component 1302 to slide on the body 1340.

[0052] Furthermore, to facilitate the movement of the telescopic mechanism 1300 on the body 1340 of the land vehicle 1000, in some embodiments, reference is made to... Figure 8 The separation and engagement mechanism 1900 also includes a motion mechanism 1320, which is located on the vehicle body 1340 and on one side of the telescopic mechanism 1300. The motion mechanism 1320 is movably connected to the sliding assembly 1301 and is used to drive the sliding assembly 1301 and the supporting assembly 1302 to move towards the outside of the vehicle body 1340 of the land vehicle 1000. The motion mechanism 1320 is located inside the vehicle body 1340. The motion mechanism 1320 may include a drive device, a lead screw, and a movable seat. The drive device is connected to the lead screw, and the sliding assembly 1301 of the telescopic mechanism 1300 is mounted on the movable seat. The drive device drives the lead screw to rotate, and the lead screw can drive the movable seat to move through a threaded transmission, thereby allowing the movable seat to move along the length of the lead screw. The telescopic mechanism 1300 connected to the movable seat also moves along the length of the lead screw along with the movable seat. When the movable seat moves toward the outside of the vehicle body 1340 of the land vehicle 1000, the movable seat can drive the sliding component 1301 and the bearing component 1302 of the telescopic mechanism 1300 to move toward the outside of the vehicle body 1340 of the land vehicle 1000, thereby allowing the bearing component 1302 to extend out of the vehicle body 1340 and carry the aircraft 2000.

[0053] To reduce wear and tear on the load-bearing assembly 1302 from the aircraft 2000, in some embodiments, reference is made to... Figure 9The telescopic mechanism 1300 includes a scratch-resistant plate 1303, which contacts the bottom of the aircraft 2000. Multiple scratch-resistant plates 1303 can be provided, positioned on top of the support assembly 1302 to prevent wear and tear on the bottom of the aircraft 2000. Furthermore, the bottom of the aircraft 2000 can be entirely made of carbon fiber, and an aluminum plate can be provided on the side of the aircraft 2000. This aluminum plate can contact the scratch-resistant plate 1303, preventing it from scratching the surface of the support assembly 1302 and causing damage or corrosion.

[0054] In order to detect the altitude position of the aircraft 2000 and ensure that the altitude of the aircraft 2000 is adjusted, in some embodiments, reference is made to... Figure 9 The land vehicle 1000 of this application is equipped with an altitude detection sensor 1350, which is positioned facing the aircraft 2000 to detect the altitude position of the aircraft 2000. The altitude detection sensor 1350 may be positioned on top of the support assembly 1302, with a gap between it and the anti-scratch plate 1303 to prevent the aircraft 2000 from pressing against the altitude detection sensor 1350. Optionally, the altitude detection sensor 1350 may be a laser sensor to detect changes in the altitude position of the aircraft 2000 through signal abrupt changes in the laser sensor.

[0055] Furthermore, the land vehicle 1000 of this application also includes a suspension system, which is disposed on the vehicle body 1340 and is used to adjust the vehicle body 1340 to sink or rise relative to the guide wheel assembly 2004 according to the detection signal of the height detection sensor 1350.

[0056] When the altitude sensor 1350 detects a change in the altitude of the aircraft 2000, the suspension system installed on the body 1340 of the land vehicle 1000 can adjust the body 1340 to sink or rise relative to the guide wheel assembly 2004.

[0057] Specifically, refer to Figure 10 The vehicle body 1340 includes a front end 1341 and a rear end 1342. The front end 1341 is located at the end of the vehicle body 1340 away from the aircraft 2000, and the rear end 1342 is located at the end of the vehicle body 1340 closer to the aircraft 2000. The suspension system is used to lower the front end 1341 and raise the rear end 1342; the telescopic mechanism 1300 is configured to tilt upward as the rear end 1342 rises, thereby raising the aircraft 2000 it carries.

[0058] The suspension system can be an air suspension mechanism. The air suspension system can control the raising and lowering of the front 1341 and rear 1342 of the land vehicle 1000 separately.

[0059] In some embodiments, the suspension system can control the front of the vehicle 1341 to rise and the rear of the vehicle 1342 to fall; alternatively, it can control the front of the vehicle 1341 to fall and the rear of the vehicle 1342 to rise. Thus, this application achieves a front-low and rear-high posture by lowering the front of the vehicle 1341 and raising the rear of the vehicle 1342 through the "seesaw" principle, or a front-high and rear-low posture by raising the front of the vehicle 1341 and lowering the rear of the vehicle 1342.

[0060] When the suspension system controls the front 1341 of the land vehicle 1000 to sink and controls the rear 1342 to rise, the telescopic mechanism 1300 located at the rear 1342 rises, thereby causing the telescopic mechanism 1300 to lift the aircraft 2000 carried on the telescopic mechanism 1300. After being lifted, the aircraft 2000 can enter the inclined section 1311 of the guide structure 1310. Then, the aircraft 2000 can be pulled towards the interior of the vehicle body 1340 of the land vehicle 1000 by the traction mechanism installed on the vehicle body 1340 of the land vehicle 1000, so that the aircraft 2000 can slide into the chute section 1312 along the guide direction of the inclined section 1311. The aircraft 2000 can slide into the interior of the vehicle body 1340 of the land vehicle 1000 within the chute section 1312, thereby allowing the aircraft 2000 to enter the interior of the vehicle body 1340 of the land vehicle 1000.

[0061] Because the telescopic mechanism 1300 extends outward and supports the aircraft 2000, and the aircraft 2000 is relatively heavy, the weight of the aircraft 2000 itself presses down on the telescopic mechanism 1300, causing the telescopic mechanism 1300 to sink when it slides on the motion mechanism 1320. To prevent the sinking telescopic mechanism 1300 from damaging the inner bottom surface of the vehicle body 1340, in some embodiments, the land vehicle 1000 also includes a scratch-resistant limiting block 1330, which is located at the bottom of the telescopic mechanism 1300 and is used to support the sinking telescopic mechanism 1300. The number of anti-scratch limit blocks 1330 can be set to multiple. Multiple anti-scratch limit blocks 1330 can be installed into the vehicle body 1340 by screws and set at the bottom of the telescopic mechanism 1300 to support the sinking telescopic mechanism 1300, thereby reducing the scraping of the inner ground of the vehicle body 1340 when the telescopic mechanism 1300 slides on the moving mechanism 1320.

[0062] Furthermore, the body 1340 of the land vehicle 1000 is provided with a reinforcing rib, and the anti-scratch limiting block 1330 is installed on the reinforcing rib, with the reinforcing rib perpendicular to the anti-scratch limiting block 1330.

[0063] The vehicle body 1340 has multiple reinforcing ribs. Two anti-scratch limiting blocks 1330 are installed on and perpendicular to the reinforcing ribs, allowing the reinforcing ribs to support the weight of the two anti-scratch limiting blocks 1330 and preventing the sinking telescopic mechanism 1300 from scraping the inner bottom surface of the vehicle body 1340.

[0064] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
