Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to door sill beams, vehicle bodies, and vehicles. Background Technology

[0002] With the increasing frequency of urban flooding and the growing demand for off-road and emergency rescue applications, improving the water-crossing capabilities of ordinary vehicles has become an important direction for automotive safety design. When vehicles pass through flooded sections of road, it is necessary to ensure the airtightness of the passenger compartment, the normal operation of the power system, and sufficient buoyancy to prevent sinking.

[0003] In existing technologies, multi-layered foldable buoyancy airbags are installed in the vehicle chassis or wheel arch area. Normally, these airbags are compactly stored in a dedicated shell. When the vehicle is wading through water, a water level sensor triggers an air supply device to inflate the airbags, causing them to expand outwards and form auxiliary floats, thereby increasing the overall buoyancy of the vehicle.

[0004] However, the scheme is complex. During the deployment of the buoyancy device, the inflation and deployment process takes a long time, and the vehicle has not yet obtained sufficient buoyancy support. This can easily lead to continuous sinking and tilting, resulting in a rapid increase in wading depth and posing a safety hazard of increased water ingress or even capsizing. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a door sill beam, a vehicle body, and a vehicle, which aims to solve the problem of vehicles sinking after wading through water in the prior art.

[0006] In a first aspect, embodiments of this application provide a door sill beam suitable for a vehicle. The door sill beam includes a beam body, a flow channel is provided within the beam body, the flow channel extends along the length direction of the vehicle, and an injection port penetrating into the flow channel is provided on the lower surface of the beam body.

[0007] Based on the aforementioned technical features, the sill beam provided in this application can directly draw water from the wading environment when the vehicle is wading through water, pressurize it, and then input it into the flow channel. Subsequently, it can be ejected at a relatively high speed through a nozzle connected to the flow channel. Within a short time after the vehicle has waded through water, it can provide the vehicle with a force opposite to the direction of the high-pressure fluid injection, thus assisting the vehicle in floating. This design enables a faster response when the vehicle is wading through water, providing force to the vehicle. Combined with the sealed passenger compartment, this allows the vehicle to float stably in the water, preventing the vehicle from sinking due to a slow response of the flotation device.

[0008] In some embodiments, the sill beam includes multiple sets of spray nozzles arranged along the length direction, each set of spray nozzles including at least one spray nozzle.

[0009] Based on the above technical features, multiple sets of injection nozzles are arranged along the length of the vehicle. Through the sill beam, multiple auxiliary forces are provided to the vehicle along the length of the vehicle, pointing from the bottom of the vehicle to the top of the vehicle. This ensures that most areas of the vehicle along the length of the vehicle can receive the auxiliary force from the liquid ejected from the injection nozzles, making the vehicle float more stably on the water.

[0010] In some embodiments, along the length of the vehicle, the beam body has a first end and a second end, and two adjacent sets of injection ports arranged sequentially along the direction from the first end to the second end are respectively the first set of injection ports and the second set of injection ports; the number of injection ports in the first set of injection ports is greater than the number of injection ports in the second set of injection ports; and / or, the orifice diameter of the injection ports in the first set of injection ports is greater than the orifice diameter of the injection ports in the second set of injection ports.

[0011] Based on the above technical features, the first set of injection nozzles can provide a greater auxiliary force than the second set of injection nozzles, making the part of the vehicle near the first end of the beam body higher than the part of the vehicle near the second end of the beam body. This allows one end of the vehicle along its length to be higher than the other end along its length, enabling components that cannot come into contact with water or cannot be submerged in water to be placed at the higher end of the vehicle, thereby preventing damage to the vehicle.

[0012] In some embodiments, along the direction from the front of the vehicle to the rear of the vehicle, the beam body includes a first beam segment, a second beam segment, and a third beam segment connected in sequence, and the injection port includes a third set of injection ports, a fourth set of injection ports, and a fifth set of injection ports. The third set of injection ports is disposed on the first beam segment, the fourth set of injection ports is disposed on the second beam segment, and the fifth set of injection ports is disposed on the third beam segment. At least one set of the third set of injection ports, the fourth set of injection ports, and the fifth set of injection ports is used to inject fluid to adjust the tilt of the vehicle.

[0013] Based on the above technical features, the vehicle's tilt in the water can be adjusted by spraying fluid through at least one of the third, fourth, and fifth sets of injection nozzles, according to the specific condition of the vehicle, thereby adjusting the vehicle's attitude in the water and enabling the vehicle to be in a safer state in the water.

[0014] In some embodiments, the flow channel includes a first sub-flow channel, a second sub-flow channel, and a third sub-flow channel arranged along the width direction of the vehicle. The first sub-flow channel is connected to a third group of injection ports, the second sub-flow channel is connected to a fourth group of injection ports, and the third sub-flow channel is connected to a fifth group of injection ports.

[0015] Based on the aforementioned technical features, high-pressure fluid can be supplied to the third group of nozzles through the first sub-channel, high-pressure fluid to the fourth group of nozzles through the second sub-channel, and high-pressure fluid to the fifth group of nozzles through the third sub-channel. This facilitates control over which specific group of nozzles sprays water, while also providing a simple and stable structure.

[0016] In some embodiments, the flow channel extends through the beam body along its length, and one end of the flow channel is the outlet; the threshold beam also includes a flow guiding component, which is disposed at the outlet and connected to the beam body, and the flow guiding component is used to adjust the flow direction of the fluid at the outlet.

[0017] Based on the aforementioned technical features, the high-pressure fluid in circulation is ejected from the outlet. The high-pressure fluid ejected from the outlet provides a driving force to the vehicle from the rear towards the inlet, thereby enabling the vehicle to move forward in the water. When the high-pressure fluid ejected from the outlet flows through the guide assembly, the guide assembly can guide the flow direction of the high-pressure fluid, thereby changing the direction of the driving force applied to the vehicle by the high-pressure fluid, and thus changing the vehicle's forward direction, enabling the vehicle to turn on the water surface.

[0018] In some embodiments, the flow guiding assembly includes flow guiding fan blades and a rotating shaft, the axis of which is aligned with the height direction of the vehicle, the rotating shaft is rotatably connected to the beam body, and the flow guiding fan blades are connected to the rotating shaft, or the rotating shaft is connected to the beam body, and the flow guiding fan blades are rotatably connected to the rotating shaft.

[0019] Based on the above technical features, this design is simple and stable, and at the same time enables the vehicle to achieve more precise and stable steering in water.

[0020] In some embodiments, the beam body includes a beam body and a jetting element connected to the beam body, the jetting element and the beam body forming a flow channel, and the jetting nozzle is disposed on the jetting element.

[0021] Based on the aforementioned technical features, the connection between the main beam and the spraying component ensures the height of the sill beam, giving it sufficient strength to increase the vehicle's rigidity and collision resistance. Simultaneously, the spraying component and the main beam form a flow channel, allowing the sill beam to spray high-pressure fluid through the nozzle, thus assisting the vehicle in floating on water.

[0022] In some embodiments, the beam body includes a first beam portion and a second beam portion, the second beam portion and the spray member are both connected to the lower surface of the first beam portion, and the spray member is located inside the second beam portion along the width direction of the vehicle.

[0023] Based on the above technical features, the second beam can protect the flow channel from the impact of the external environment, and the first beam is located above the spraying component, thereby providing upper protection for the flow channel and preventing structural damage to the flow channel.

[0024] In some embodiments, the beam body includes a surrounding plate and a reinforcing plate, the surrounding plate being disposed around the reinforcing plate and forming multiple reinforcing cavities with the reinforcing plate.

[0025] Based on the above technical features, the structural strength of the main beam can be increased by the reinforcing plates and reinforcing cavities inside the enclosure, thereby enabling the sill beam to meet the structural strength requirements and protect the flow channel from deformation due to external impacts.

[0026] Secondly, this application provides a vehicle body including the sill beam provided in the first aspect of this application.

[0027] Thirdly, this application provides a vehicle including the body provided in the second aspect of this application. Attached Figure Description

Detailed Implementation

[0031] The terms "first," "second," etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Directional terms used in this application, such as "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," are merely for reference to the orientation shown in the accompanying drawings. The use of directional terms is for better and clearer explanation and understanding of this application, and does not indicate the orientation of the referred device or component in an actual application scenario.

[0032] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the two parts can rotate relative to each other after connection. "Sliding connection" refers to a connection where the two parts can slide relative to each other after connection.

[0033] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0034] The terms "parallel" and "perpendicular" are relative to the current technological level, not absolute mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between them ranging from 0 to 5 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between them ranging from 85 to 95 degrees.

[0035] The term "electrical connection" refers to the flow of current or signal from one conductor to another. An electrical connection between A and B means that current or signal can flow from A to B and vice versa. This connection includes direct and indirect electrical connections. A direct electrical connection between A and B means that A and B are physically connected. An indirect electrical connection between A and B means that A and B are connected via C, where C can be at least one wire or device.

[0036] The embodiments of this application are described below with reference to the accompanying drawings.

[0037] This application provides a vehicle, which can be a passenger vehicle or a freight vehicle, and can also be an electric vehicle or a hybrid vehicle. This application does not limit the specific purpose or power type of the vehicle, and the choice can be made according to actual needs.

[0038] In some embodiments, a vehicle may include a body, which forms the framework of the entire vehicle and can support and connect components such as the vehicle's engine, motor, and transmission system. The body can withstand various loads (such as vibration, impact, and torsion) during vehicle operation. Furthermore, in the event of a collision, the body, through its rational structural design, absorbs and disperses impact energy to protect the safety of the occupants.

[0039] like Figure 1 As shown, in some embodiments, the vehicle may include a sill beam extending along the length direction A of the vehicle, and the sill beam may be connected to the front longitudinal beam and the rear longitudinal beam. When the vehicle is an electric vehicle, the sill beam may also be connected to the battery pack frame. This application does not limit the specific connection method of the sill beam in the vehicle body, and it can be selected according to actual conditions such as cost and manufacturing process. The main function of the sill beam is to enhance the overall rigidity of the vehicle body, ensuring the stability and handling of the vehicle during driving. At the same time, when the vehicle is subjected to a side collision, the sill beam can effectively absorb and disperse the impact force, reducing injury to the occupants.

[0040] like Figures 1 to 3As shown, in some embodiments, the sill beam includes a beam body 10, within which a flow channel 11 is provided. The flow channel 11 extends along the length direction A of the vehicle, and a nozzle 12 penetrating into the flow channel 11 is provided on the lower surface of the beam body 10. When the sill beam is installed inside the vehicle, the nozzle 12 is located on the side of the sill beam away from the roof. In some possible examples, when the vehicle is positioned on the ground and in a normal driving or stationary state, the nozzle 12 may face the ground.

[0041] The beam body 10 extends along the length direction A of the vehicle. The beam body 10 serves primarily as a sill beam, bearing load and resisting collisions. In some possible examples, the interior of the beam body 10 may contain a cavity to increase structural strength; this cavity can serve as a flow channel 11. In other possible examples, a pipe may be installed inside the beam body 10 to serve as the flow channel 11. This application does not limit the specific structure of the flow channel 11; it can be selected based on cost, manufacturing process, and other practical considerations.

[0042] In some possible examples, the vehicle may also include a high-pressure pump body connected to the flow channel 11 via a pipe. When the vehicle wades through water and partially submerges along its height direction C, the high-pressure pump body can activate, drawing fluid from the wading area and pressurizing it before transmitting it through the pipe into the flow channel 11. The high-pressure fluid flows within the flow channel 11 and is ejected from the nozzle 12, providing an upward force to the vehicle—a force opposite to the direction of the fluid ejected from the nozzle 12 (hereinafter referred to as the auxiliary force)—to assist the vehicle in buoyancy. It is important to note that the vehicle's buoyancy is primarily achieved through a sealed passenger compartment. The sealed passenger compartment prevents water from entering after wading; its interior is primarily air, with an average density less than that of water. This ensures that the vehicle's total mass is less than the sum of the auxiliary force exerted on the vehicle by the high-pressure fluid ejected from the nozzle 12 and the buoyancy exerted on the vehicle by the water in the environment, allowing the vehicle to float on the water's surface.

[0043] The sill beam provided in this application can directly draw fluid from the wading environment when the vehicle is wading through water, pressurize it, and then input it into the flow channel 11. It can then be ejected at a relatively high speed through the injection port 12 connected to the flow channel 11. Within a short time after the vehicle has waded through water, it can provide the vehicle with a force opposite to the direction of the high-pressure fluid injection, thus assisting the vehicle in floating. This design allows for a faster response when the vehicle is wading through water, providing force to the vehicle. Combined with the sealed passenger compartment, this enables the vehicle to float stably in the water, preventing the vehicle from sinking due to a slow response of the flotation device.

[0044] In some possible examples, the vehicle may also include a detector for detecting water entrapment. Exemplarily, the detector may be mounted on the sill beam; when the sill beam is submerged in water, the detector comes into contact with the water surface, and a high-pressure pump draws water from the environment. The detector may also be located at the suction port of the high-pressure pump. This application does not limit the specific location of the detector; it can be selected based on design and manufacturing considerations.

[0045] like Figure 4 , Figure 5 as well as Figure 7 As shown, in some embodiments, the sill beam includes multiple sets of injection ports 12 arranged along the length direction A, each set of injection ports 12 including at least one injection port 12. In some possible examples, each set of injection ports 12 may contain multiple injection ports 12; exemplarily, the multiple injection ports 12 may be arranged along the width direction B of the vehicle. In other possible examples, the multiple injection ports 12 may also be arranged in a matrix. This application does not limit the specific number of injection ports 12 in each set of injection ports 12, and the number can be selected according to actual conditions such as cost and manufacturing process. The number of injection ports 12 in each set of injection ports 12 may be 4, 5, or 15. In other possible examples, the number of injection ports 12 in each set of injection ports 12 may also be 1. This application does not limit the specific number of injection ports 12 in each set of injection ports 12, and the number can be selected according to actual conditions such as design and manufacturing process.

[0046] Generally, vehicles have two sill beams, located on either side of the vehicle's width direction (B) at the bottom of the vehicle body. These beams provide auxiliary force to the vehicle from both sides of width direction (B). The sill beams extend from one end of the passenger compartment along the length direction (A) to the other end, making their dimension along the vehicle's length direction (A) approximately 40% to 60% of the overall length of the vehicle. In mid-to-large-sized vehicles or pure electric vehicles, due to battery pack placement requirements, the sill beams are often longer, potentially approaching 60% or even higher. Furthermore, the sill beams pass through the middle of the vehicle's length direction (A).

[0047] Based on this, by arranging multiple sets of injection nozzles 12 along the length direction A of the vehicle, multiple auxiliary forces can be provided to the vehicle along the length direction A from the bottom of the vehicle to the top of the vehicle through the sill beam. In some possible examples, the above-mentioned multiple auxiliary forces are all applied to the middle position and / or near the middle position of the length direction A of the vehicle, so that most areas of the vehicle along the length direction A can be subject to the auxiliary force provided by the liquid sprayed from the injection nozzles 12, making the vehicle float more stably on the water surface.

[0048] like Figure 1 and Figure 5As shown, in some embodiments, along the length direction A of the vehicle, the beam body 10 has a first end and a second end. In some possible examples, along the direction from the first end to the second end, the first end of the beam body 10 may be the end of the beam body 10 closer to the front of the vehicle, and the second end of the beam body 10 may be the end of the beam body 10 closer to the rear of the vehicle.

[0049] Along the direction from the first end to the second end, adjacent sets of injection ports 12 are arranged sequentially as the first set of injection ports 121 and the second set of injection ports 122. In some possible examples, the beam body 10 may have three sets of injection ports 12 along the length direction A of the vehicle, which may be a front injection port 12, a middle injection port 12, and a rear injection port 12. The front injection port 12, the middle injection port 12, and the rear injection port 12 are arranged sequentially along the direction from the first end to the second end. For the front injection port 12 and the middle injection port 12, the front injection port 12 can be the first set of injection ports 121, and the middle injection port 12 can be the second set of injection ports 122. For the middle injection port 12 and the rear injection port 12, the middle injection port 12 can be the first set of injection ports 121, and the rear injection port 12 can be the second set of injection ports 122.

[0050] In some other possible examples, the beam body 10 may be provided with four, five or more sets of injection ports 12 along the length direction A of the vehicle. However, the definition of the first set of injection ports 121 and the second set of injection ports 122 is the same as the definition of the beam body 10 being provided with three sets of injection ports 12 along the length direction A. For details, please refer to the above description, which will not be repeated here.

[0051] In some possible examples, the number of nozzles 12 in the first group of nozzles 121 is greater than the number of nozzles 12 in the second group of nozzles 122. This arrangement allows the first group of nozzles 121 to eject a larger amount of water, resulting in a greater auxiliary force on the beam body 10 at the location where the first group of nozzles 121 is located. Conversely, the second group of nozzles 122 ejects a smaller amount of water, resulting in a smaller auxiliary force on the beam body 10 at the location where the second group of nozzles 122 is located. Based on this, when the beam body 10 is submerged in water, the first end can be positioned higher than the second end.

[0052] In some other possible examples, the orifice diameter of the nozzle 12 in the first set of nozzles 121 is larger than the orifice diameter of the nozzle 12 in the second set of nozzles 122. This arrangement allows the first set of nozzles 121 to eject a larger amount of water, while the second set of nozzles 122 ejects a smaller amount of water compared to the first set of nozzles 121. In other possible examples, the number of nozzles 12 in the first set of nozzles 121 is greater than the number of nozzles 12 in the second set of nozzles 122, and the orifice diameter of the nozzles 12 in the first set of nozzles 121 may also be larger than the orifice diameter of the nozzles 12 in the second set of nozzles 122.

[0053] In some possible examples, when components of the vehicle that cannot come into contact with water, such as the motor and / or engine, or parts that cannot be submerged in water over a large area, are located at the front of the vehicle, the first end of the beam body 10 can be closer to the front of the vehicle than the second end. This arrangement can make the front of the vehicle higher than the rear of the vehicle through a larger auxiliary force, preventing components in the front of the vehicle that cannot come into contact with water from coming into contact with water, or reducing the area of ​​components that cannot be submerged in water from coming into contact with water, thereby preventing damage to the vehicle.

[0054] In some other possible examples, when components of the vehicle, such as the motor and / or engine, that cannot come into contact with water or cannot be submerged in water over a large area are located at the rear of the vehicle, the first end of the beam body 10 can be closer to the rear of the vehicle than the second end. This arrangement can make the rear of the vehicle higher than the front of the vehicle by using a larger auxiliary force.

[0055] With this configuration, the first set of spray nozzles 121 provides a greater auxiliary force than the second set of spray nozzles 122, making the part of the vehicle near the first end of the beam body 10 higher than the part of the vehicle near the second end of the beam body 10. This allows one end of the vehicle along the length direction A to be higher than the other end of the vehicle along the length direction A. Components that cannot come into contact with water or cannot be submerged in water over a large area can be placed at the higher end of the vehicle, thereby preventing damage to the vehicle.

[0056] like Figure 6 and Figure 7As shown, in some embodiments, along the direction from the front of the vehicle to the rear of the vehicle, the beam body 10 includes a first beam segment 13, a second beam segment 14, and a third beam segment 15 connected sequentially. Exemplarily, the first beam segment 13, the second beam segment 14, and the third beam segment 15 may be integrally formed. Alternatively, the first beam segment 13, the second beam segment 14, and the third beam segment 15 may be welded. This application does not limit the specific connection method between the first beam segment 13, the second beam segment 14, and the third beam segment 15; the choice can be made based on actual conditions such as cost and process. The second beam segment 14 is located between the first beam segment 13 and the third beam segment 15. The first beam segment 13 is closer to the front of the vehicle than the second beam segment 14, and the third beam segment 15 is closer to the rear of the vehicle than the second beam segment 14.

[0057] The injection port 12 includes a third group of injection ports 123, a fourth group of injection ports 124, and a fifth group of injection ports 125. The third group of injection ports 123 is disposed on the first beam segment 13, the fourth group of injection ports 124 is disposed on the second beam segment 14, and the fifth group of injection ports 125 is disposed on the third beam segment 15. At least one of the third group of injection ports 123, the fourth group of injection ports 124, and the fifth group of injection ports 125 is used to inject fluid to adjust the tilt of the vehicle.

[0058] In some possible examples, if the front of the vehicle sinks too much due to the weight of the vehicle or interference from objects in the water during the wading process, high-pressure fluid can be sprayed through the third set of nozzles 123 set on the first beam segment 13 to provide auxiliary force to the front of the vehicle, while the fourth set of nozzles 124 and the fifth set of nozzles 125 do not spray high-pressure fluid, thereby causing the front of the vehicle to rise.

[0059] Similarly, if the rear of the vehicle sinks excessively, high-pressure fluid can be injected through the fifth set of injection ports 125 provided on the third beam segment 15, while the third set of injection ports 123 and the fourth set of injection ports 124 do not inject high-pressure fluid. Under the action of auxiliary force, the rear of the vehicle can be raised. If the entire vehicle is in a sunken state, the third set of injection ports 123, the fourth set of injection ports 124, and the fifth set of injection ports 125 can all be opened, thereby raising the entire vehicle under the action of auxiliary force. This application does not limit which specific injection ports 12 of the third set of injection ports 123, the fourth set of injection ports 124, and the fifth set of injection ports 125 inject high-pressure fluid; the selection can be made according to the actual situation such as design and process.

[0060] This configuration allows for the adjustment of the vehicle's tilt in the water by spraying fluid through at least one of the third group of spray nozzles 123, the fourth group of spray nozzles 124, and the fifth group of spray nozzles 125, depending on the specific condition of the vehicle. This adjustment aims to improve the vehicle's posture in the water and ensure a safer condition for the vehicle.

[0061] In some possible examples, the vehicle may include an attitude detection sensor that can detect the vehicle's attitude in the water, determine which part of the vehicle has waded too much water and needs adjustment, and control at least one of the third group of jet nozzles 123, the fourth group of jet nozzles 124 and the fifth group of jet nozzles 125 to open, thereby automatically adjusting the vehicle's attitude in the water.

[0062] like Figure 6 and Figure 7 As shown, in some embodiments, the flow channel 11 includes a first sub-flow channel 111, a second sub-flow channel 112, and a third sub-flow channel 113 arranged along the width direction B of the vehicle. In some possible examples, two baffles extending along the length direction A can be provided within the flow channel 11 of the beam body 10 along the width direction B to divide the flow channel 11 into the first sub-flow channel 111, the second sub-flow channel 112, and the third sub-flow channel 113. In other possible embodiments, the first sub-flow channel 111, the second sub-flow channel 112, and the third sub-flow channel 113 can also be three water pipes. This application does not limit the specific structure of the first sub-flow channel 111, the second sub-flow channel 112, and the third sub-flow channel 113, and they can be selected according to actual conditions such as process and cost.

[0063] The first sub-channel 111 is connected to the third group of injection ports 123, the second sub-channel 112 is connected to the fourth group of injection ports 124, and the third sub-channel 113 is connected to the fifth group of injection ports 125. In some possible examples, the first sub-channel 111, the second sub-channel 112, and the third sub-channel 113 can be arranged sequentially along the width direction B and in the direction from the outside of the vehicle to the inside of the vehicle. At the same time, along the width direction B and in the direction from the outside of the vehicle to the inside of the vehicle, the surface of the beam body 10 where the injection ports 12 are provided can be divided into a first region, a second region, and a third region arranged sequentially. The third group of injection ports 123 is provided on the first region to facilitate the connection between the third group of injection ports 123 and the first sub-channel 111. The fourth group of injection ports 124 is provided on the second region to facilitate the connection between the fourth group of injection ports 124 and the second sub-channel 112. The fifth group of injection ports 125 is provided on the third region to facilitate the connection between the fifth group of injection ports 125 and the third sub-channel 113.

[0064] This configuration allows for the supply of high-pressure fluid to the third set of nozzles 123 via the first sub-channel 111, the supply of high-pressure fluid to the fourth set of nozzles 124 via the second sub-channel 112, and the supply of high-pressure fluid to the fifth set of nozzles 125 via the third sub-channel 113. This facilitates control over which set of nozzles 12 is used to inject high-pressure fluid, while also ensuring a simple and stable structure.

[0065] like Figure 2 , Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, in some embodiments, the flow channel 11 extends through the beam body 10 along the length direction A, with one end of the flow channel 11 serving as an outlet and the other end as an inlet. In some possible examples, the inlet may also be located at the end of the first beam segment 13 away from the second beam segment 14, and the outlet may also be located at the end of the third beam segment 15 away from the second beam segment 14. The outlet may face the side away from the front of the vehicle.

[0066] In some possible examples, the inlet can be connected to the output port of the high-pressure pump body, enabling the high-pressure pump body to input high-pressure fluid into the flow channel 11. As the high-pressure fluid passes through the injection port 12, it is ejected from the injection port 12, thus providing an upward auxiliary force to the vehicle. Subsequently, the high-pressure fluid in circulation is ejected from the outlet, providing a driving force from the rear of the vehicle towards the inlet, thereby enabling the vehicle to move forward in the water. Exemplarily, a high-pressure nozzle 30 can also be provided at the inlet to increase the pressure of the fluid flowing in. The high-pressure nozzle is provided with a first connection 31 and a second connection 32. The first connection 31 is used to connect to the output port of the high-pressure pump body, and the second connection 32 is used to connect to the beam body 10 and communicate with the inlet.

[0067] In some possible examples, the first sub-channel 111 may include a first inlet and a first outlet, the second sub-channel 112 may include a second inlet and a second outlet, and the third channel 11 may include a third inlet and a third outlet. The vehicle also includes a valve whose inlet can communicate with the outlet of the high-pressure pump body. The valve may include a first connection port, a second connection port, and a third connection port. The first connection port is connected to the first inlet, the second connection port is connected to the second inlet, and the third connection port is connected to the third inlet.

[0068] When the third set of nozzles 123 needs to spray high-pressure fluid, the inlet can be connected to the first connecting port to allow the high-pressure fluid to flow into the first sub-channel 111. When the fourth set of nozzles 124 needs to spray high-pressure fluid, the inlet can be connected to the second connecting port to allow the high-pressure fluid to flow into the second sub-channel 112. When the fifth set of nozzles 125 needs to spray high-pressure fluid, the inlet can be connected to the third connecting port to allow the high-pressure fluid to flow into the third sub-channel 113.

[0069] The sill beam also includes a flow guide assembly 20, which is disposed at the outlet and connected to the beam body 10. In some possible examples, the flow guide assembly 20 may be sealed to the beam body 10. Exemplarily, a seal may be provided between the flow guide assembly 20 and the beam body 10. The flow guide assembly 20 and the beam body 10 may be bolted together or welded together. This application does not limit the specific connection method between the flow guide assembly 20 and the beam body 10, and the method can be selected according to actual conditions such as process and cost.

[0070] The flow guide assembly 20 is used to adjust the flow direction of the fluid at the outlet. When the high-pressure fluid ejected from the outlet flows through the flow guide assembly 20, the flow guide assembly 20 can guide the flow direction of the high-pressure fluid, thereby changing the direction of the driving force applied to the vehicle by the high-pressure fluid, and thus changing the forward direction of the vehicle, so that the vehicle can turn on the water surface.

[0071] like Figure 1 and Figure 8 As shown, in some embodiments, the flow guiding assembly 20 includes a flow guiding fan blade 21 and a rotating shaft, the axis of which is aligned with the vehicle's height direction C. In some possible examples, the rotating shaft is rotatably connected to the beam body 10, and the flow guiding fan blade 21 is connected to the rotating shaft. Exemplarily, the rotating shaft can be rotatably connected to the beam body 10 via a bearing, or a mounting groove can be provided on the beam body 10, through which the rotating shaft is rotatably connected. The flow guiding fan blade 21 can be integrally formed with the rotating shaft, or it can be welded together. The relative rotation of the rotating shaft relative to the beam body 10 causes the rotating shaft to drive the flow guiding fan blade 21 to rotate, thereby allowing the flow guiding fan blade 21 to adjust the flow direction of the fluid at the outlet. This configuration is simple and stable, and enables the vehicle to achieve more precise and stable steering in water.

[0072] In other possible examples, the flow guiding assembly 20 may be equipped with a mounting base 22 located at the outlet and connected to the beam body 10. A rotating shaft is connected to the mounting base 22, and the flow guiding fan blade 21 is rotatably connected to the rotating shaft. Exemplarily, the rotating shaft and the beam body 10 may be welded together, or they may be rotatably connected by bolts. The flow guiding fan blade 21 may be rotatably connected to the rotating shaft via bearings. The flow guiding fan blade 21 may have a shaft hole, and the rotatable connection between the flow guiding fan blade 21 and the rotating shaft is achieved through a clearance fit between the shaft hole and the rotating shaft. The rotation of the flow guiding fan blade 21 relative to the rotating shaft allows the flow direction of the fluid at the outlet to be adjusted.

[0073] In some possible examples, a rotating motor can be provided, which can be connected to the rotating shaft or the guide fan blades 21 to drive the rotating shaft or the guide fan blades 21 to rotate. This application does not limit the specific connection method between the guide fan blades 21 and the rotating shaft, or the driving method between the guide fan blades 21 and the rotating shaft, which can be selected according to the actual situation such as design and process.

[0074] In other possible embodiments, the flow guiding component 20 may also be a nozzle structure, which can spray high-pressure fluid to the outside. By changing the orientation of the nozzle structure, the steering of the vehicle can be controlled. This application does not limit the specific structure of the flow guiding component 20, and it can be selected according to actual conditions such as cost and process.

[0075] like Figure 3 and Figure 6 As shown, in some embodiments, the beam body 10 includes a beam body 16 and a spray element 17 connected to the beam body 16. The spray element 17 and the beam body 16 form a flow channel 11, and a spray nozzle 12 is disposed on the spray element 17. The spray element 17 can form the flow channel 11 together with the outer wall of the beam body 16. The main function of the beam body 16 is to improve the rigidity of the vehicle body, enhance the impact resistance during side collisions, provide installation support for the doors, and help protect the integrity of the passenger compartment in an accident.

[0076] Exemplarily, the spraying component 17 and the beam body 16 can be integrally formed, or they can be welded together. This application does not limit the specific connection method between the spraying component 17 and the beam body 16; the method can be selected based on actual conditions such as cost and process. In some possible examples, the spraying component 17 can have a flow channel groove, and the spray nozzle 12 can be disposed on the bottom wall of the flow channel groove. The inner wall of the flow channel groove and the outer wall of the beam body 16 form a flow channel 11.

[0077] In some other possible examples, the spray element 17 may be composed of a first plate-shaped structure 171, a second plate-shaped structure 172, and a third plate-shaped structure 173. The first plate-shaped structure 171 and the second plate-shaped structure 172 are arranged along the width direction B of the vehicle. Both the first plate-shaped structure 171 and the second plate-shaped structure 172 are located below the beam body 16 along the height direction C. The third plate-shaped structure 173 is connected to the side of the first plate-shaped structure 171 away from the beam body 10, and the third plate-shaped structure 173 is connected to the side of the second plate-shaped structure 172 away from the beam body 10, so that the first plate-shaped structure 171, the second plate-shaped structure 172, the third plate-shaped structure 173, and the beam body 10 form a flow channel 11. The third plate-shaped structure 173 has a spray nozzle 12.

[0078] This configuration, through the connection between the main beam 16 and the spray nozzle 17, ensures the height of the sill beam by the main beam 16, giving the sill beam sufficient strength to increase the rigidity of the vehicle body and its collision resistance. Simultaneously, the spray nozzle 17 and the main beam 16 form a flow channel 11, allowing the sill beam to spray high-pressure fluid through the spray nozzle 12, thereby assisting the vehicle in floating on the water surface.

[0079] like Figure 3 and Figure 6 As shown, in some embodiments, the beam body 16 includes a first beam portion 161 and a second beam portion 162. The second beam portion 162 and the spray member 17 are both connected to the lower surface of the first beam portion 161. The lower surface of the first beam portion 161 can be the surface of the first beam portion 161 away from the vehicle roof. Exemplarily, the first beam portion 161 and the second beam portion 162 can be integrally formed, or they can be welded together. This application does not limit the specific connection method between the first beam portion 161 and the second beam portion 162, and the method can be selected according to actual conditions such as cost and process.

[0080] The spray nozzle 17 is located inside the second beam 162 along the width direction B of the vehicle. The inside of the second beam 162 can be understood as the side of the second beam 162 furthest from the vehicle's external environment. In other words, the second beam 162 is closer to the vehicle's external environment than the spray nozzle 17. This arrangement allows the second beam 162 to protect the flow channel 11 from impacts from the external environment. The first beam 161 is positioned above the spray nozzle 17, thus providing upper protection for the flow channel 11 and preventing structural damage to it.

[0081] like Figure 3 and Figure 6 As shown, in some embodiments, the beam body 16 includes a surrounding plate 163 and a reinforcing plate 164. The surrounding plate 163 surrounds the reinforcing plate 164 and together with the reinforcing plate 164, forms a plurality of reinforcing cavities 165. In some possible examples, the surrounding plate 163 forms a cavity of the beam body 16, and the reinforcing plate 164 is connected to the interior of the surrounding plate 163, thereby dividing the cavity of the surrounding plate 163 into a plurality of reinforcing cavities 165. In other possible examples, there may be multiple reinforcing plates 164. Some of the multiple reinforcing plates 164 may be arranged along the height direction C, and another part of the multiple reinforcing plates 164 may be arranged along the width direction B, thereby forming a plurality of reinforcing cavities 165. With this arrangement, the structural strength of the beam body 16 can be increased by the reinforcing plates 164 and the reinforcing cavities 165 inside the surrounding plate 163, thereby enabling the sill beam to meet the structural strength requirements and protecting the flow channel 11 from deformation due to external impacts.

[0082] For example, the reinforcing plate 164 and the surrounding plate 163 can be integrally formed, or the reinforcing plate 164 and the surrounding plate 163 can be welded. This application does not limit the specific connection method between the reinforcing plate 164 and the surrounding plate 163, and the connection method can be selected according to the actual situation such as cost and process.

Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this application still fall within the scope of this application.
