Description

Technical Field

[0001] This utility model relates to the field of flying vehicle technology, and in particular to amphibious vehicles. Background Technology

[0002] An amphibious vehicle is a mode of transportation that can both fly and travel on land; it is a combination of an aircraft and a vehicle. Currently, in order to ensure that the flight power of manned amphibious vehicles can meet the takeoff weight, most manned amphibious vehicles are usually equipped with a large number of rotors.

[0003] One existing technology for meeting the road driving requirements of vehicles with a width of less than 2.55m is to separate the manned amphibious vehicle into a flying body and a land-based body. When driving on the road, the flying body is detached from the land-based body to ensure that the width of the land-based body meets the driving requirements. However, this requires manpower, space, and assembly / disassembly equipment, which is costly. Another approach is to install folding wings on the manned amphibious vehicle. When the manned amphibious vehicle is in the air, the folding wings unfold and extend to both ends of the vehicle's width. When the manned amphibious vehicle is on the road, the folding wings fold and are stored on the top of the vehicle. However, the folding wings are long, and even when folded, part of them still lies outside the two ends of the vehicle's width, which does not meet the requirements for road driving. Utility Model Content

[0004] The purpose of this invention is to provide an amphibious vehicle to solve the aforementioned problems existing in existing amphibious vehicles.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Amphibious vehicles, including:

[0007] Vehicle body;

[0008] A first ducted fan assembly is disposed at the bottom of the vehicle body. The first ducted fan assembly includes multiple first ducted fans, which are all located between a first side and a second side in the width direction of the vehicle body and between the two sides in the length direction of the vehicle body. The distance between the first side and the second side is the maximum width of the vehicle body. The first ducted fans are used to provide lift to the amphibious vehicle for upward flight.

[0009] Two second ducted fan assemblies are disposed on the top of the vehicle body and configured to switch between a working position and a standby position. When the two second ducted fan assemblies are in the working position, one second ducted fan assembly extends at least partially from the first side along the width direction of the vehicle body, and the other second ducted fan assembly extends at least partially from the second side along the width direction of the vehicle body. When the two second ducted fan assemblies are in the standby position, both second ducted fan assemblies are located between the first and second sides along the width direction of the vehicle body and between the two sides along the length direction of the vehicle body. The second ducted fan assemblies are used to provide lift to the amphibious vehicle for upward flight.

[0010] As a preferred embodiment of the aforementioned amphibious vehicle, the amphibious vehicle further includes a drive mechanism disposed on the top of the vehicle body. The drive mechanism includes a first drive motor, and a meshing worm gear and worm. The output shaft of the first drive motor is drivenly connected to the input end of the worm and can drive the worm to rotate around its own central axis. The worm gear is drivenly connected or fixedly connected to two second ducted fan groups. The worm gear can drive the two second ducted fan groups to rotate and switch between the working position and the standby position.

[0011] As a preferred embodiment of the aforementioned amphibious vehicle, the amphibious vehicle further includes a drive mechanism disposed on the top of the vehicle body. The drive mechanism includes a second drive motor and two ball screw assemblies, with the two ball screw assemblies corresponding one-to-one with the two second ducted fan groups.

[0012] The ball screw assembly includes a threaded ball screw and a nut. The output shaft of the second drive motor is connected to the two ball screws. The second drive motor can drive the two ball screws to rotate around their own central axis so that the two nuts move closer or further apart along the axial direction of the ball screws. The nuts are fixedly connected to the second ducted fan assembly. The axial direction of the ball screws is parallel to the width direction of the vehicle body.

[0013] As a preferred embodiment of the aforementioned amphibious vehicle, when the two second ducted fan assemblies are in the working position, both second ducted fan assemblies are located between the front wheel and the rear wheel of the vehicle body.

[0014] As a preferred embodiment of the aforementioned amphibious vehicle, when the two second ducted fan groups are in the working position, the center positions of the two second ducted fan groups are located on the same straight line, and the straight line is parallel to the width direction of the vehicle body.

[0015] As a preferred embodiment of the aforementioned amphibious vehicle, the first ducted fan assembly includes four first ducted fans, wherein two of the first ducted fans are located in front of the front wheel axle of the vehicle body and are spaced apart along the width direction of the vehicle body, and the remaining two first ducted fans are located behind the rear wheel axle of the vehicle body and are spaced apart along the width direction of the vehicle body.

[0016] As a preferred embodiment of the aforementioned amphibious vehicle, the vehicle body is equipped with a steering wheel and a seat, both of which are located in the middle area of ​​the vehicle body along the width direction.

[0017] As a preferred embodiment of the aforementioned amphibious vehicle, the number of seats is two, and the two seats are spaced apart along the length of the vehicle body.

[0018] As a preferred embodiment of the aforementioned amphibious vehicle, the vehicle body is a pure electric vehicle, and the battery of the vehicle body is a solid-state battery.

[0019] As a preferred embodiment of the aforementioned amphibious vehicle, the battery is fixedly mounted on the chassis of the vehicle body and located between the front wheel and the rear wheel of the vehicle body.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides an amphibious vehicle, comprising a vehicle body, a first ducted fan assembly disposed at the bottom of the vehicle body, and two second ducted fan assemblies disposed at the top of the vehicle body. The first ducted fan assembly includes multiple first ducted fans, each located between a first and a second side in the width direction of the vehicle body and between both sides in the length direction of the vehicle body. The distance between the first and second sides is the maximum width of the vehicle body. The first ducted fans provide lift to the amphibious vehicle for upward flight. The two second ducted fan assemblies are configured to switch between a working position and a standby position. When both second ducted fan assemblies are in the working position, one second ducted fan assembly extends at least partially from the first side in the width direction of the vehicle body, and the other second ducted fan assembly extends at least partially from the second side in the width direction of the vehicle body. When both second ducted fan assemblies are in the standby position, both second ducted fan assemblies are located between the first and a second side in the width direction of the vehicle body and between both sides in the length direction of the vehicle body. The second ducted fan assemblies provide lift to the amphibious vehicle for upward flight.

[0022] When the amphibious vehicle is to travel in the air, the two second ducted fan groups are switched to the working position. One second ducted fan group extends at least partially to the first side along the width direction of the vehicle body, and the other second ducted fan group extends at least partially to the second side along the width direction of the vehicle body. The multiple first ducted fans of the first ducted fan group are distributed at the bottom of the vehicle body. The first ducted fan group and the second ducted fan group together provide lift to the amphibious vehicle to enable it to travel in the air.

[0023] When the amphibious vehicle is to travel on the road, the two second ducted fan groups are switched to the standby position. Both second ducted fan groups are located between the first and second sides in the width direction of the vehicle body and between the two sides in the length direction of the vehicle body. This ensures that the two second ducted fan groups do not increase the width and length of the amphibious vehicle. Secondly, multiple first ducted fans are located between the first and second sides in the width direction of the vehicle body and between the two sides in the length direction of the vehicle body. Again, multiple first ducted fans do not increase the width and length of the amphibious vehicle. This allows the amphibious vehicle to effectively meet the requirements for road travel. Compared with the existing technology of separating the flying body from the land-based body to ensure that the width of the land-based body meets the driving requirements, this can effectively reduce the operating cost of the amphibious vehicle when traveling on the road.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] To meet the road driving requirements for vehicles with a width of less than 2.55m, one existing technology involves separating the manned amphibious vehicle into an airborne and a land-based component. When driving on the road, the airborne component is detached from the land-based component to ensure that the width of the land-based component meets the driving requirements. However, this requires manpower, space, and assembly / disassembly equipment, resulting in high costs. Another approach is to install folding wings on the manned amphibious vehicle. When the vehicle is in the air, the folding wings unfold and extend to both ends of the vehicle's width. When the vehicle is on the road, the folding wings fold and are stored on the top of the vehicle. However, the folding wings are long, and even when folded, a portion of them remains outside the two ends of the vehicle's width, which does not meet the requirements for road driving.

[0045] Therefore, this utility model provides an amphibious vehicle, such as... Figure 1-4 and Figure 6-8As shown, the amphibious vehicle includes a vehicle body 1, a first ducted fan assembly located at the bottom of the vehicle body 1, and two second ducted fan assemblies 3 located at the top of the vehicle body 1. The first ducted fan assembly includes multiple first ducted fans 2, all located between a first side and a second side in the width direction of the vehicle body 1 and between both sides in the length direction of the vehicle body 1. The distance between the first side and the second side is the maximum width of the vehicle body 1. The first ducted fans 2 are used to provide lift to the amphibious vehicle for upward flight. Two second ducted fan assemblies 3 are configured to switch between a working position and a standby position; when the two second ducted fan assemblies 3 are in the working position, one second ducted fan assembly 3 extends at least partially to a first side along the width direction of the vehicle body 1, and the other second ducted fan assembly 3 extends at least partially to a second side along the width direction of the vehicle body 1; when the two second ducted fan assemblies 3 are in the standby position, both second ducted fan assemblies 3 are located between the first and second sides in the width direction of the vehicle body 1 and between the two sides in the length direction of the vehicle body 1; the second ducted fan assemblies 3 are used to provide lift for the amphibious vehicle to fly upwards.

[0046] When the amphibious vehicle is to travel in the air, the two second ducted fan groups 3 are switched to the working position. One second ducted fan group 3 extends at least partially to the first side along the width direction of the vehicle body 1, and the other second ducted fan group 3 extends at least partially to the second side along the width direction of the vehicle body 1. The multiple first ducted fans 2 of the first ducted fan group are distributed at the bottom of the vehicle body 1. The first ducted fan group and the second ducted fan group 3 together provide lift to the amphibious vehicle to enable it to travel in the air.

[0047] When the amphibious vehicle is to travel on the road, the two second ducted fan groups 3 are switched to the standby position. Both second ducted fan groups 3 are located between the first and second sides in the width direction of the vehicle body 1 and between the two sides in the length direction of the vehicle body 1. This ensures that the two second ducted fan groups 3 do not increase the width and length of the amphibious vehicle. Secondly, multiple first ducted fans 2 are located between the first and second sides in the width direction of the vehicle body 1 and between the two sides in the length direction of the vehicle body 1. Multiple first ducted fans 2 also do not increase the width and length of the amphibious vehicle. This allows the amphibious vehicle to effectively meet the requirements for road travel. Compared with the prior art of separating the flying body from the land-based body to ensure that the width of the land-based body meets the driving requirements, this can effectively reduce the driving cost of the amphibious vehicle when traveling on the road.

[0048] Specifically, such as Figure 2 As shown, the distance between the first side and the second side is L, where L is the maximum width of the vehicle body 1.

[0049] Preferably, such as Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the first ducted fan 2 is fixedly mounted on the bottom of the vehicle body 1. By adjusting the rotational speed of each first ducted fan 2, the amphibious vehicle can move forward, backward, and turn. Compared to rotatably connecting the first ducted fan 2 to the bottom of the vehicle body 1, this avoids the need to install a drive device on the vehicle body 1 to adjust the attitude of the first ducted fan 2, thus preventing the drive device from increasing the weight and cost of the amphibious vehicle. The specific structure of the first ducted fan 2 and its connection structure to the bottom of the vehicle body 1 are existing technologies and will not be described further here.

[0050] Preferably, along the height direction of the vehicle body 1, the fan blades of the first duct fan 2 are disposed near the bottom of the duct housing of the first duct fan 2.

[0051] Specifically, along the height direction of the vehicle body 1, the bottom of the duct housing of the first ducted fan 2 is flush with the bottom guard plate 11. The top of the duct housing of the first ducted fan 2 is connected to the top of the vehicle body 1, so that the first ducted fan 2 can draw air from the top of the vehicle body 1.

[0052] The amphibious vehicle also includes a drive mechanism located on the top of the vehicle body 1. The drive mechanism is used to drive the two second ducted fan groups 3 to switch between the working position and the standby position.

[0053] In some embodiments, such as Figure 1-5 As shown, the drive mechanism includes a first drive motor 41, and a meshing worm gear 42 and worm 43. The output shaft of the first drive motor 41 is connected to the input end of the worm 43 and can drive the worm 43 to rotate around its own central axis. The worm gear 42 is connected to or fixedly connected to two second ducted fan groups 3, and can drive the two second ducted fan groups 3 to rotate and switch between the working position and the standby position. When the amphibious vehicle is to travel in the air, the first drive motor 41 drives the worm gear 42 and worm 43 to rotate the two second ducted fan groups 3 to the working position; when the amphibious vehicle is to travel on the ground, the first drive motor 41 drives the worm gear 42 and worm 43 to rotate the two second ducted fan groups 3 to the standby position. Compared with the prior art of attaching and detaching the flying body from the land-based body, this method can effectively improve the efficiency of switching the driving mode of the amphibious vehicle, including the road driving mode and the air driving mode.

[0054] Specifically, for transmission via meshing worm gear 42 and worm 43, when the lead angle of worm 43 is less than the equivalent friction angle between the meshing teeth, worm gear 42 and worm 43 possess self-locking properties. These self-locking properties are used to lock the positions of the two second ducted fan groups 3, simplifying the structure of the drive mechanism.

[0055] Furthermore, such as Figure 5 As shown, for transmission via meshing worm gear 42 and worm 43, the drive mechanism further includes two first fixed arms 44, each corresponding to one of the two second ducted fan groups 3. One end of each first fixed arm 44 is fixedly connected to the worm gear 42, and the other end is fixedly connected to the second ducted fan group 3. Specifically, the other end of each first fixed arm 44 is fixedly connected to the duct housing of the second ducted fan group 3. This enables the two second ducted fan groups 3 to rotate around the central axis of the worm gear 42 to the working position, and also enables them to rotate around the central axis of the worm gear 42 to the ready-to-work position. As an alternative, the drive mechanism further includes two first gear transmission assemblies, each corresponding to one of the two first fixed arms 44; the input gears of both first gear transmission assemblies are coaxially fixed to the worm gear 42; the output gear of each first gear transmission assembly is fixedly connected to one end of a corresponding first fixed arm 44, and the other end of the first fixed arm 44 is fixedly connected to the duct housing of a corresponding second ducted fan group 3. It can also switch the two second ducted fan groups 3 between the working position and the standby position.

[0056] In other embodiments, such as Figure 6-9As shown, the drive mechanism includes a second drive motor 51 and two ball screw assemblies 52, with each ball screw assembly 52 corresponding to one of the two second ducted fan groups 3. Each ball screw assembly 52 includes a threaded lead screw 521 and a nut 522. The output shaft of the second drive motor 51 is connected to the two lead screws 521, enabling the second drive motor 51 to rotate the two lead screws 521 around their own central axis, causing the two nuts 522 to move closer to or further away from each other along the axial direction of the lead screws 521. The nuts 522 are fixedly connected to the second ducted fan group 3. The axial direction of the lead screw 521 is parallel to the width direction of the vehicle body 1. When the amphibious vehicle is to travel in the air, the second drive motor 51 drives the two lead screws 521 to rotate around their central axis, causing the two nuts 522 to move away from each other, and causing the two second ducted fan assemblies 3 to move away from each other along the width direction of the vehicle body 1, so that the two second ducted fan assemblies 3 can move to the working position. When the amphibious vehicle is to travel on the ground, the second drive motor 51 drives the two lead screws 521 to rotate around their central axis, causing the two nuts 522 to move closer together, and causing the two second ducted fan assemblies 3 to move closer together along the width direction of the vehicle body 1, so that the two second ducted fan assemblies 3 can move to the ready-to-work position. Compared with the existing technology of attaching and detaching the flying body from the land-based body, this also effectively improves the efficiency of switching the driving mode of the amphibious vehicle.

[0057] Furthermore, such as Figure 9 As shown, for transmission via the ball screw assembly 52, the drive mechanism also includes two second fixed arms 53, which are respectively configured to correspond one-to-one with the two second ducted fan assemblies 3. One end of the second fixed arm 53 is fixedly connected to the nut 522, and the other end of the second fixed arm 53 is fixedly connected to the duct housing of the second ducted fan assembly 3.

[0058] Furthermore, such as Figure 9 As shown, for transmission via the ball screw assembly 52, the drive mechanism further includes a second gear transmission assembly 54. The input gear of the second gear transmission assembly 54 is connected to the input shaft of the second drive motor 51, and the output gear of the second gear transmission assembly 54 is connected to the two lead screws 521. This allows the second drive motor 51 to drive the two lead screws 521 to rotate synchronously around their own central axis.

[0059] In other embodiments, the drive mechanism includes an electric actuator or a cylinder, which drives the two second ducted fan groups 3 to move closer or further apart along the width direction of the vehicle body 1, allowing the two second ducted fan groups 3 to switch between a working position and a standby position. The specific structures of the electric actuator and the cylinder are prior art and will not be described in detail here.

[0060] Preferably, such as Figure 4 and Figure 8 As shown, when the two second ducted fan assemblies 3 are in the working position, both second ducted fan assemblies 3 are located between the front wheel 12 and the rear wheel 13 of the vehicle body 1. This arrangement, when the two second ducted fan assemblies 3 are in the working position, improves the flight stability and maneuverability of the amphibious vehicle compared to when both second ducted fan assemblies 3 are located at the front or rear end along the length of the vehicle body 1. More preferably, in this embodiment, when the two second ducted fan assemblies 3 are in the working position, the distance between the two second ducted fan assemblies 3 and the axle of the front wheel 12 along the length of the vehicle body 1 is greater than the distance between the two second ducted fan assemblies 3 and the axle of the rear wheel 13. As an alternative, when the two second ducted fan assemblies 3 are in the working position, the distance between the two second ducted fan assemblies 3 and the axle of the front wheel 12 along the length of the vehicle body 1 is equal to or less than the distance between the two second ducted fan assemblies 3 and the axle of the rear wheel 13.

[0061] Preferably, such as Figure 4 and Figure 8 As shown, when the two second ducted fan groups 3 are in the operating position, their centers are aligned on the same straight line. This straight line is parallel to the width direction of the vehicle. This further enhances the flight stability and maneuverability of the amphibious vehicle.

[0062] Preferably, such as Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, the first ducted fan assembly includes four first ducted fans 2. Two of the first ducted fans 2 are located in front of the axle of the front wheel 12 of the vehicle body 1 and are spaced apart along the width direction of the vehicle body 1. The remaining two first ducted fans 2 are located behind the axle of the rear wheel 13 of the vehicle body 1 and are also spaced apart along the width direction of the vehicle body 1. This arrangement, in conjunction with the two second ducted fan assemblies 3, can ensure the maximum takeoff weight of the amphibious vehicle while reducing its overall weight. More preferably, the four first ducted fans 2 are located at the four corners of the vehicle body 1, corresponding one-to-one. It is understood that the number of first ducted fans 2 and the distribution position of each first ducted fan 2 can be adaptively increased or decreased according to actual operating conditions.

[0063] Preferably, in this embodiment, such as Figure 1-4 and Figure 6-8As shown, the second ducted fan assembly 3 includes one second ducted fan. It is understood that the second ducted fan assembly 3 can also be adapted to include at least two second ducted fans, depending on actual operating conditions. The specific structure of the second ducted fan is prior art and will not be described in detail here.

[0064] Preferably, such as Figure 1 , Figure 3 and Figure 6 As shown, the vehicle body 1 is equipped with a steering wheel 61 and a seat 62, both of which are located in the middle area along the width direction of the vehicle body 1. This reduces the width of the vehicle body 1 and further reduces the weight of the amphibious vehicle, thereby ensuring the maximum takeoff weight for the amphibious vehicle.

[0065] More preferably, such as Figure 1 , Figure 3 and Figure 6 As shown, there are two seats 62, which are spaced apart along the length of the vehicle body 1. This further reduces the width of the vehicle body 1 and the weight of the amphibious vehicle, thereby ensuring the maximum takeoff weight for the amphibious vehicle.

[0066] It is understandable that the number of seats 62 can be increased or decreased according to actual working conditions, and the distribution of the steering wheel 61 and seats 62 within the vehicle body 1 can be adjusted.

[0067] More preferably, the vehicle body 1 is a pure electric vehicle, and the battery 63 of the vehicle body 1 is a solid-state battery. Compared with using liquid batteries or engine systems, this can further reduce the weight of the amphibious vehicle, thereby further ensuring the maximum takeoff weight of the amphibious vehicle.

[0068] More preferably, the vehicle body 1 is a pure electric rear-wheel drive vehicle. This improves the handling of the amphibious vehicle when driving on roads. As an alternative, the vehicle body 1 is a pure electric front-wheel drive vehicle. As yet another alternative, the vehicle body 1 is a pure electric four-wheel drive vehicle.

[0069] Specifically, such as Figure 1 , Figure 3 and Figure 6 As shown, the battery 63 is fixedly mounted on the chassis of the vehicle body 1 and is located between the front wheel 12 and the rear wheel 13 of the vehicle body 1.

[0070] The specific structure of the vehicle body 1 is existing technology, so it will not be described in detail here.
