[0002] A sea-air amphibious vehicle is a vehicle that combines the functions of an aerial vehicle and an underwater submersible. It can adapt to both air and water environments and can play an important role in various missions such as military reconnaissance, rescue operations, cargo transportation and scientific research.

[0003] At present, the sea and air amphibious vehicles sold and used on the market are generally modified from multi-axis unmanned aerial vehicles. They can only operate in water at low speed for a short time by paddling with flying rotors. Since the paddling efficiency of aviation rotors is low, the power of the driving motor needs to be increased to ensure the navigation speed when traveling in water, which causes a sharp increase in the load on the driving motor. Therefore, the existing flying devices of this type can only temporarily lurk in the shallow surface of the water body, with a very short underwater working time, without a true diving mode, and are unable to perform diving tasks.

[0010] As a preferred technical solution of the present invention, the hub is bullet-shaped, and the diameter of the hub gradually decreases from a side close to the adjacent mounting column to a side away from the adjacent mounting column.

[0011] As a preferred technical solution of the present invention, a first mounting ring is fixedly connected to a side of the spline rod close to the adjacent one-way clutch, a circumferentially evenly distributed connecting rod is fixedly connected to a side of the first mounting ring close to the adjacent one-way clutch, a second mounting ring is commonly fixedly connected to a side of the circumferentially evenly distributed connecting rod away from the adjacent first mounting ring, a friction ring is commonly slidably connected to the circumferentially evenly distributed connecting rods, a circumferentially evenly distributed spring is arranged between the friction ring and the adjacent second mounting ring, the friction ring is extruded and frictionally fitted with the adjacent mounting shell, a rotating ring is rotatably connected to a side of the mounting shell away from the adjacent one-way clutch, and a circumferentially evenly distributed tension spring is arranged between the rotating ring and the adjacent second mounting ring.

This is only for the convenience of describing the present application and simplifying the description. It does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0022] Embodiment 1: An auxiliary submersible sea and air amphibious drive device, such as Figure 1-Figure 4 As shown, it includes a control cabin 1, which is provided with four driving cabins 2 evenly distributed in the circumference. A dual-axis brushless motor 3 is fixedly connected in the driving cabin 2 through three support rods evenly distributed in the circumference. The output shaft on the lower side of the dual-axis brushless motor 3 is fixedly connected to a propeller 4, and the propeller 4 is used for paddling when the device is in a submerged state. The output shaft on the upper side of the dual-axis brushless motor 3 is fixedly connected to a mounting shell 5, and a one-way clutch 6 is slidably fitted on the upper side of the mounting shell 5. The one-way clutch 6 is an existing device, which is used to enable adjacent mounting shells 5 to only drive adjacent spline rods 9 to rotate clockwise from the top view direction. Three circumferentially evenly distributed sliding grooves are provided on the outer side of the one-way clutch 6, and three circumferentially evenly distributed convex columns 7 are fixedly connected in the mounting shell 5. The convex columns 7 are squeezed and fitted with adjacent sliding grooves on adjacent one-way clutches 6. When the mounting shell 5 drives the three convex columns 7 thereon to rotate, the convex columns 7 rotate relative to the adjacent one-way clutches 6, thereby squeezing adjacent sliding grooves on adjacent one-way clutches 6, so that the adjacent one-way clutches are engaged and disengaged. The device 6 moves upward, and a bearing 8 is fixedly connected in the drive cabin 2 through three support rods evenly distributed in the circumference. The bearing 8 is used to provide support for the adjacent spline rod 9. The cross-section of the support rod for fixing the dual-axis brushless motor 3 and the bearing 8 is elliptical, which is used to reduce the resistance of the support rod to the airflow and water flow. The inner side spline of the bearing 8 is connected with the spline rod 9 fixed to the inner side of the adjacent one-way clutch 6. When the mounting shell 5 drives the outer side of the adjacent one-way clutch 6 to rotate clockwise from the top view, the outer side of the one-way clutch 6 drives its inner side to rotate. When the mounting shell 5 drives the outer side of the adjacent one-way clutch 6 to rotate counterclockwise from the top view, the outer side of the one-way clutch 6 cannot drive its inner side to rotate. A mounting column 10 is fixedly connected to the upper side of the spline rod 9. The mounting column 10 is fixedly connected to three articulated seats 11 evenly distributed in the circumference. The side of the articulated seat 11 away from the adjacent mounting column 10 is rotatably connected to a rotating rod 12, and the side of the rotating rod 12 away from the adjacent articulated seat 11 is fixed to a rotor 13.

[0023] like Figure 1 , Figure 2 and Figure 4As shown, the mounting column 10 is slidably matched with the propeller hub 14, and the propeller hub 14 is provided with three circumferentially evenly distributed sliding grooves, the upper side of the sliding grooves is inclined, and the lower side is horizontal, the articulated seat 11 is slidably matched with the adjacent sliding grooves on the adjacent propeller hub 14, and when the mounting column 10 drives the adjacent articulated seat 11 to rotate, the propeller hub 14 rotates relative to the adjacent articulated seat 11 under the action of inertia, so that the articulated seat 11 squeezes the adjacent sliding grooves on the adjacent propeller hub 14, and then the propeller hub 14 moves up and down, and the rotating rod 12 is limitedly matched with the adjacent sliding grooves on the adjacent propeller hub 14. When the rotating rod 12 moves to the lower side of the adjacent sliding grooves on the adjacent propeller hub 14, the rotating rod 12 is stuck, thereby increasing the stability of the rotor 13 during flight, and a A spring is in a compressed state and is used to reset the adjacent rotor 13. The adjacent rotating rod 12 is located on the inner side of the spring. The lower side of the slide groove on the hub 14 is in a horizontal state, and the depth of the lower side of the slide groove on the hub 14 is greater than the length of the adjacent hinge seat 11. The depth of the upper side of the slide groove on the hub 14 is less than the length of the adjacent hinge seat 11. When the hinge seat 11 moves to the lower side of the adjacent slide groove on the adjacent hub 14, the adjacent rotating rod 12 is stuck. When the hinge seat 11 moves to the upper side of the adjacent slide groove on the adjacent hub 14, the adjacent rotating rod 12 can rotate. The hub 14 is bullet-shaped, and the diameter of the hub 14 gradually decreases from the side close to the adjacent mounting column 10 to the side away from the adjacent mounting column 10, so as to reduce the air resistance during flight.

[0024] like Figure 3 As shown, a first mounting ring 15 is fixedly connected to the lower side of the spline rod 9, three circumferentially evenly distributed connecting rods 16 are fixedly connected to the lower side of the first mounting ring 15, a second mounting ring 17 is fixedly connected to the lower side of the three connecting rods 16, a friction ring 18 is slidably connected to the three connecting rods 16, three circumferentially evenly distributed springs are arranged between the friction ring 18 and the adjacent second mounting ring 17, the springs are used to make the adjacent friction ring 18 close to the adjacent mounting shell 5, the length of the spring between the friction ring 18 and the adjacent second mounting ring 17 in the unstressed state is less than the maximum moving distance of the adjacent one-way clutch 6, so that the friction ring 18 can be in contact with the adjacent The mounting shell 5 is completely separated, the friction ring 18 is squeezed and frictionally matched with the adjacent mounting shell 5. After the friction ring 18 contacts the adjacent mounting shell 5, the mounting shell 5 drives the adjacent friction ring 18 and the parts thereon to rotate. The upper side of the friction ring 18 is provided with friction material, and the lower side of the mounting shell 5 close to the adjacent friction ring 18 is provided with friction material, so that the transmission between the friction ring 18 and the adjacent mounting shell 5 is more stable. The lower side of the mounting shell 5 is rotatably connected with a rotating ring 19, and three circumferentially evenly distributed tension springs are provided between the rotating ring 19 and the adjacent second mounting ring 17, and the tension springs are used to reset the adjacent second mounting ring 17 and the parts thereon.

[0025] When the device is in use, the device includes two states: flight and diving. In the flight state, the dual-axis brushless motor 3 is started, and the dual-axis brushless motor 3 drives the adjacent propeller 4 and the mounting shell 5 to rotate clockwise from the top view direction, and the mounting shell 5 drives the three adjacent bosses 7 to rotate. Because the one-way clutch 6 has inertia, the mounting shell 5 will rotate relative to the adjacent one-way clutch 6 when driving the adjacent boss 7 to rotate. At this time, the boss 7 slides and squeezes relative to the adjacent slide groove on the adjacent one-way clutch 6. Under the squeezing of the adjacent boss 7, the one-way clutch 6 rotates and moves upward. At this time, the one-way clutch 6 drives the adjacent spline rod 9 to rotate, and the spline rod 9 drives the inner ring of the adjacent bearing 8 to rotate, and the spline rod 9 slides upward relative to the adjacent bearing 8. The spline rod 9 drives the parts thereon to rotate and move upward. When the mounting column 10 drives the three adjacent articulated seats 11 to rotate, the hub 14 is in inertia. Under the action of the force, the articulated seat 11 produces relative rotation with the adjacent articulated seat 11. At this time, the articulated seat 11 squeezes the adjacent slide groove on the adjacent propeller hub 14 to move it upward. During the movement, the rotating rod 12 drives the adjacent spring to move, and the spring slides relative to the adjacent propeller hub 14. The distance between the adjacent rotor 13 and the adjacent propeller hub 14 gradually increases, and the spring gradually stretches. When the articulated seat 11 drives the adjacent rotating rod 12 and the rotor 13 to rotate, under the action of centrifugal force, the rotor 13 rotates and unfolds relative to the adjacent rotating rod 12. At this time, the articulated seat 11 gradually slides from a position where the depth of the adjacent groove on the adjacent propeller hub 14 is shallow to a position where the depth is deeper, until the articulated seat 11 drives the adjacent rotating rod 12 to move to the horizontal part of the adjacent groove of the adjacent propeller hub 14, and the rotating rod 12 is clamped by the horizontal part of the adjacent groove of the adjacent propeller hub 14, thereby increasing the stability of the rotating rod 12 and the rotor 13 during flight of the device.

[0026] When the device switches from a submerged state to a flying state, the spline rod 9 moves upward, and the spline rod 9 drives the adjacent first mounting ring 15 and the parts thereon to move upward. When the second mounting ring 17 moves upward, the adjacent tension spring is stretched. After the second mounting ring 17 pushes the adjacent friction ring 18 to move upward for a distance through the adjacent spring, the friction ring 18 contacts the adjacent mounting shell 5. At this time, the first mounting ring 15 continues to drive the adjacent second mounting ring 17 to move upward through the adjacent connecting rod 16 and compress the adjacent spring. The pressure between the friction ring 18 and the adjacent mounting shell 5 gradually increases. Then, the dual-axis brushless motor 3 drives the adjacent propeller 4 and the rotor 13 to rotate rapidly. The propeller 4 quickly discharges the water in the adjacent drive cabin 2, thereby reducing the time taken for the device to switch from a submerged state to a flying state.

[0027] When the device switches from the flight state to the diving state, the dual-axis brushless motor 3 is controlled to gradually decelerate and reverse, and the dual-axis brushless motor 3 drives the adjacent propeller 4 and the mounting shell 5 to rotate counterclockwise from the top view direction, and the mounting shell 5 drives the adjacent three protrusions 7 to rotate counterclockwise, and the protrusion 7 squeezes the adjacent one-way clutch 6 to move downward, and the one-way clutch 6 drives the adjacent spline rod 9 to move downward. At the same time, the mounting shell 5 drives the adjacent friction ring 18 to rotate through friction, and the friction ring 18 transmits the adjacent first mounting ring 18 through the adjacent connecting rod 16. The mounting ring 15 rotates counterclockwise from the top view, and the second mounting ring 17 drives the adjacent spline rod 9 to move downward under the action of the adjacent spring. At this time, the spline rod 9 drives the adjacent mounting column 10 to move downward while rotating, and the mounting column 10 drives the adjacent hinge seat 11 to rotate. When the hinge seat 11 rotates, it squeezes the adjacent hub 14 to move downward. When the hinge seat 11 leaves the adjacent horizontal part of the slide groove on the adjacent hub 14, the rotating rod 12 loses the limit of the adjacent hub 14. At this time, because the spline rod 9 drives the parts on it to move downward, the rotor 13 When the spring is fully opened, the rotor 13 is about to move to the upper side of the adjacent slide groove on the adjacent propeller hub 14. At this time, the spring adjacent to the rotor 13 pushes the adjacent propeller hub 14 obliquely downward, so that the rotor 13 continues to move to the adjacent hub 14. The moving rod 12 contacts the upper side of the adjacent slide groove on the adjacent hub 14. At this time, the tension spring adjacent to the rotating ring 19 pulls the adjacent second mounting ring 17 and the parts thereon to reset, so that the adjacent friction ring 18 is separated from the adjacent mounting shell 5. At this time, the transmission between the mounting shell 5 and the adjacent spline rod 9 is disconnected by the one-way clutch 6, so that the adjacent rotor 13 is in a stationary state. At this time, the rotor 13 is in a retracted state, which can reduce the resistance encountered by the device in a submerged state. At the same time, the rotor 13 can also act as a guide plate to improve the stability of the device when submerged.

[0028] Embodiment 2: Based on embodiment 1, Figure 5 As shown, it also includes limiting columns 20 that are uniformly distributed in a circumferential direction and in a circular array. The three limiting columns 20 are respectively slidably connected to adjacent hinge seats 11. A spring is arranged between the limiting columns 20 and the adjacent hinge seats 11. The spring is used to provide power for the adjacent limiting columns 20 to limit the adjacent rotating rods 12. The rotating rod 12 is provided with a groove that cooperates with the adjacent limiting columns 20. The limiting column 20 is inserted into the groove of the adjacent rotating rod 12 to make the rotating rod 12 and the parts thereon more stable.

[0029] When the rotor 13 is in a horizontal state after being unfolded, the adjacent limiting posts 20 are inserted into the grooves of the adjacent rotating rods 12 under the action of the adjacent springs, thereby fixing the adjacent rotating rods 12 and increasing the stability of the adjacent rotors 13 when rotating. When the rotor 13 is retracted, the rotor 13 drives the adjacent rotating rods 12 to rotate, and the grooves of the rotating rods 12 squeeze the adjacent limiting posts 20, causing the limiting posts 20 to move away from the adjacent rotating rods 12 and compress the adjacent springs, thereby releasing the limiting posts 20 from limiting the adjacent rotating rods 12.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
