Description

Technical Field

[0001] The present invention belongs to the technical field of amphibious vehicles, and particularly relates to an amphibious vehicle water area auxiliary buoyancy and motion attitude control system and vehicle. Background Art

[0002] With the rapid development of modern technology and the continuous improvement of people's living standards, the demand of automobile users for travel modes is becoming increasingly diversified. Especially in terms of the requirement for travel safety, it has reached an unprecedented height. Against this background, the multi-amphibious development trend of civilian vehicles is becoming more and more obvious, that is, the vehicle not only needs to have the ability to travel on land, but also should be able to conduct emergency passage in complex environments such as water areas.

[0003] At present, the automotive industry has carried out preliminary exploration and practice in response to this demand, and has launched a series of civilian vehicles with preliminary amphibious functions. For example, some models have realized the emergency floating function after the vehicle falls into the water by installing a reverse thrust floating device and using components such as a water spray pipe and a water spray pump. These devices can provide a certain buoyancy for the vehicle in an emergency, help the vehicle stay on the water surface, and thus increase the survival chance of passengers.

[0004] In addition, the emergence of technologies such as vehicle controllers and floating water control systems has further improved the safety and stability of vehicles when passing through water areas. These systems can identify the floating water mode of the vehicle and perform intelligent control according to the actual situation to ensure the smooth driving of the vehicle in the water area.

[0005] However, although these technologies meet the basic needs of civilian amphibious vehicles to a certain extent, there are still many challenges in actual applications. Due to the overall layout limitation of civilian amphibious vehicles, the layout of large solid hydrofoils has become a difficult problem. As an effective device for realizing auxiliary buoyancy, solid hydrofoils can significantly improve the navigation speed and stability of vehicles in water areas. However, in civilian amphibious vehicles, due to limited space, it is difficult to install large solid hydrofoils, thus restricting their performance in the water area passing conditions.

[0006] Therefore, it is necessary to develop a new amphibious vehicle water area auxiliary buoyancy and motion attitude control system and vehicle. Summary of the Invention

[0007] The purpose of the present invention is to provide an amphibious vehicle water area auxiliary buoyancy and motion attitude control system and vehicle, which can achieve functions similar to those of solid hydrofoils with a smaller structure.

[0008] In a first aspect, an amphibious vehicle water area auxiliary buoyancy and motion attitude control system according to the present invention includes: A power and water flow distribution unit for generating and distributing high-pressure water flow; Virtual hydrofoil unit, comprising two virtual hydrofoil generating devices, the two virtual hydrofoil generating devices are respectively connected to the power and water flow distribution unit, and each said virtual hydrofoil generating device is used to receive the high-pressure water flow distributed by the power and water flow distribution unit, and shape the high-pressure water flow into a shape equivalent to the surface of a physical hydrofoil to form a virtual hydrofoil; Control unit, comprising two virtual hydrofoil control devices, the two said virtual hydrofoil control devices are respectively connected to the two virtual hydrofoil generating devices in one-to-one correspondence, and each said virtual hydrofoil control device is used to adjust the angle of attack and sweep angle of the virtual hydrofoil generated by the corresponding virtual hydrofoil generating device.

The high-pressure water pump provides the core power source, and the water supply pipeline realizes efficient water flow distribution. The lateral double outlet ensures symmetric distribution of water flow to the two virtual hydrofoils, improving the balance of the system.

[0010] Optionally, the high-pressure water pump includes a high-pressure water pump body, a bottom water inlet provided at the bottom of the high-pressure water pump body, and lateral water outlets symmetrically arranged on the left and right sides of the high-pressure water pump body; the high-pressure water pump body sucks water through the bottom water inlet and outputs high-pressure water flow through the lateral water outlets; the high-pressure water pump adopts shaftless pump technology, and the impeller and rotor are integrally designed to achieve miniaturization of the structure.

[0011] The water supply pipeline includes two water supply pipes, one ends of the two water supply pipes are respectively connected to the two lateral water outlets in one-to-one correspondence, and the other ends of the two water supply pipes are respectively connected to the two virtual hydrofoil generating devices in one-to-one correspondence. The layout of the lateral water outlets reduces the loss of water flow turning and improves the pump efficiency. The symmetric design ensures balanced water flow pressure on both sides of the virtual hydrofoils, avoids yaw moment, and improves the navigation stability.

[0012] Optionally, the virtual hydrofoil generating device has a water inlet pipe, an angle-of-attack adjustment gear, an inner guide shell and an outer guide shell. There are gaps between the inner guide shell and the outer guide shell to form a shaping cavity. The shaping cavity is communicated with the power and water flow distribution unit through the water inlet pipe. The high-pressure water flow enters the shaping cavity through the water inlet pipe and is sprayed at high speed according to the shape of the wing surface to form a virtual hydrofoil. By forming a shaping cavity through the gap between the inner guide shell and the outer guide shell, the high-pressure water flow is constrained into a specific wing surface shape, simulating the hydrodynamic effect of a physical hydrofoil.

[0013] Optionally, there is a uniform gap between the inner guide shell and the outer guide shell to form the shaping cavity; The water inlet end of the water inlet pipe is communicated with the power and water flow distribution unit. The water outlet end of the water inlet pipe is provided with a plurality of diversion holes evenly distributed in the circumferential direction. The high-pressure water flow enters the shaping cavity through the diversion holes and is sprayed at a high speed according to the wing surface shape to form a virtual hydrofoil. The circumferentially evenly distributed diversion hole design enables the water flow to be sprayed evenly, avoiding local eddies and improving the lift coefficient and propulsion efficiency of the virtual hydrofoil.

[0014] Optionally, the virtual hydrofoil control device includes a virtual hydrofoil control housing, an angle of attack control motor assembly, an angle of attack control gear, a connecting gear, a sweep angle control motor assembly, and a sweep angle control gear; The virtual hydrofoil control housing includes an angle of attack control housing and a sweep angle control housing; Both the angle of attack control gear and the angle of attack adjustment gear of the virtual hydrofoil generating device are installed in the angle of attack control housing, and the angle of attack control gear meshes with the angle of attack adjustment gear; the angle of attack control motor assembly is connected to the angle of attack control gear, and the angle of attack control motor assembly drives the angle of attack adjustment gear to rotate through the angle of attack control gear to achieve the adjustment of the angle of attack; The sweep angle control housing is installed on the angle of attack control housing. The connecting gear and the sweep angle control gear are both installed in the sweep angle control housing, and the connecting gear meshes with the sweep angle control gear; the sweep angle control motor assembly is connected to the sweep angle control gear, and the sweep angle control motor assembly drives the angle of attack control housing to rotate through the sweep angle control gear and the connecting gear. While the angle of attack control housing rotates, it drives the virtual hydrofoil generating device to rotate to achieve the adjustment of the sweep angle. The adjustment of the angle of attack and the sweep angle is achieved through the cooperation of the motor assembly and the gear system.

[0015] Optionally, the virtual hydrofoil control device further includes a collection module, a wireless signal receiving module, and an adaptive control module. The collection module is connected to the wireless signal receiving module, the wireless signal receiving module is connected to the adaptive control module, and the adaptive control module is respectively connected to the angle of attack control motor assembly and the sweep angle control motor assembly; The collection module is used to collect the attitude and speed information of the vehicle; The wireless signal receiving module is used to receive the attitude and speed information; The adaptive control module controls the rotation direction, rotation speed, and rotation time of the angle of attack control motor assembly and the sweep angle control motor assembly based on the attitude and speed information to achieve the adjustment of the angle of attack and the sweep angle. The adaptive control module adjusts the control parameters in a closed-loop manner based on real-time sensor data (attitude, speed) to achieve dynamic optimal control. For example, when sailing at high speed, the angle of attack is automatically reduced and the sweep angle is increased; when sailing at low speed, the angle of attack is increased and the sweep angle is reduced.

[0016] Optionally, the acquisition module includes an attitude sensor and a speed sensor. The attitude sensor is used to acquire the attitude information of the vehicle; The speed sensor is used to acquire the speed information of the vehicle.

Setting the electronic devices inside the virtual hydrofoil control housing can effectively extend the service life of the electronic devices.

The amphibious vehicle water area auxiliary buoyancy and motion attitude control system is installed on the vehicle body to provide water area auxiliary buoyancy and motion attitude control for the vehicle.

[0019] Advantages of the present invention: 1.

It should be understood that the preferred embodiments are only for explaining the present invention, rather than for limiting the protection scope of the present invention.

[0026] Such as Figure 1As shown in the figure, in the embodiment of the present application, an amphibious vehicle water area auxiliary buoyancy and motion attitude control system includes a power and water flow distribution unit, a virtual hydrofoil unit, and a control unit. The power and water flow distribution unit is used to generate and distribute high-pressure water flow. The virtual hydrofoil unit includes two virtual hydrofoil generating devices 3, and the two virtual hydrofoil generating devices 3 are respectively connected to the power and water flow distribution unit. Each virtual hydrofoil generating device 3 is used to receive the high-pressure water flow distributed by the power and water flow distribution unit and shape the high-pressure water flow into a shape equivalent to the surface of a physical hydrofoil to form a virtual hydrofoil. The control unit includes two virtual hydrofoil control devices 4, and the two virtual hydrofoil control devices 4 are respectively connected to the two virtual hydrofoil generating devices 3 in one-to-one correspondence. Each virtual hydrofoil control device 4 is used to adjust the angle of attack and sweep angle of the virtual hydrofoil generated by the corresponding virtual hydrofoil generating device 3.

[0027] As Figure 1 and Figure 2 shown, in a possible embodiment, the power and water flow distribution unit includes a high-pressure water pump 1 and a water supply pipeline 2. The high-pressure water pump 1 is used to generate high-pressure water flow. The water supply pipeline 2 is used to connect the high-pressure water pump 1 and the virtual hydrofoil generating device 3 and distribute the high-pressure water flow to the two virtual hydrofoil generating devices 3.

[0028] As Figure 2 shown, in a possible embodiment, the high-pressure water pump 1 includes a high-pressure water pump body 1-2, a bottom water inlet 1-1 provided at the bottom of the high-pressure water pump body 1-2, and lateral water outlets 1-3 symmetrically arranged on the left and right sides of the high-pressure water pump body 1-2. Among them, the high-pressure water pump adopts shaftless pump technology, and the impeller and rotor are integrally designed to achieve miniaturization of the structure. The high-pressure water pump body 1-2 sucks water through the bottom water inlet 1-1 and outputs high-pressure water flow through the lateral water outlets 1-3. The water supply pipeline 2 includes two water supply pipes. One ends of the two water supply pipes are respectively connected to the two lateral water outlets 1-3 in one-to-one correspondence, and the other ends of the two water supply pipes are respectively connected to the two virtual hydrofoil generating devices 3 in one-to-one correspondence. Among them, the high-pressure water pump body 1-2 sucks water and generates high-pressure water flow by electric drive or other drive methods. After the high-pressure water pump 1 is started, it sucks water through the bottom water inlet 1-1 and outputs the high-pressure water flow generated by the high-pressure water pump body 1-2 through the lateral water outlets 1-3, and then inputs it into the virtual hydrofoil generating device 3 through the water supply pipeline 2.

[0029] As Figure 2 shown, in a possible embodiment, the high-pressure water pump 1 further includes a first mounting structure 1-4 provided at the top of the high-pressure water pump body 1-2, and the high-pressure water pump 1 is bolt-connected to the vehicle body through the first mounting structure 1-4.

[0030] As Figure 3As shown, in a possible embodiment, the virtual hydrofoil generating device 3 has a water inlet pipe 3-1, an angle of attack adjustment gear 3-3, an inner flow guide shell, and an outer flow guide shell 3-4. The water inlet end of the water inlet pipe 3-1 is communicated with the power and water flow distribution unit, specifically, the water inlet pipe 3-1 is connected to the water supply pipe on the corresponding side. There are gaps between the inner flow guide shell and the outer flow guide shell 3-4 to form a shaping cavity. The water outlet end of the water inlet pipe 3-1 passes through the angle of attack adjustment gear 3-3 and is communicated with the shaping cavity. High-pressure water flow enters the shaping cavity through the water inlet pipe 3-1 and jets at high speed according to the shape of the wing surface, forming a virtual hydrofoil. The virtual hydrofoil generating device 3 uses high-speed water flow to shape a shape equivalent to the wing surface of a physical hydrofoil, thereby realizing the equivalent function of a physical hydrofoil. This innovation not only overcomes the problem that it is difficult to install large physical hydrofoils on traditional civilian amphibious vehicles, but also significantly improves the auxiliary buoyancy and navigation performance of the vehicle in water.

The water inlet end of the water inlet pipe 3-1 is communicated with the power and water flow distribution unit, and the water outlet end of the water inlet pipe 3-1 is provided with a plurality of shunt holes 3-2 evenly distributed in the circumferential direction. The high-pressure water flow generated by the high-pressure water pump 1 is input into the water inlet pipe 3-1 of the virtual hydrofoil generating device 3 through the water supply pipeline 2, and then introduced into the shaping cavity formed by the inner flow guide shell and the outer flow guide shell 3-4 through the shunt holes 3-2, and jets at high speed according to the shaped wing surface shape to form a virtual hydrofoil to achieve the equivalent function of a physical hydrofoil and provide auxiliary buoyancy for the vehicle during navigation.

[0032] As Figure 4 and Figure 5As shown, in a possible embodiment, the virtual hydrofoil control device 4 includes a virtual hydrofoil control housing, an angle of attack control motor assembly 4-2, an angle of attack control gear 4-3, a connecting gear 4-5, a sweep angle control motor assembly 4-6, and a sweep angle control gear 4-7. The virtual hydrofoil control housing includes an angle of attack control housing 4-1 and a sweep angle control housing 4-4. The angle of attack control gear 4-3 and the angle of attack adjustment gear 3-3 of the virtual hydrofoil generating device 3 are both installed in the angle of attack control housing 4-1, and the angle of attack control gear 4-3 meshes with the angle of attack adjustment gear 3-3. The angle of attack control motor assembly 4-2 is connected to the angle of attack control gear 4-3. The angle of attack control motor assembly 4-2 provides torque for the angle of attack control gear 4-3, drives the angle of attack adjustment gear 3-3 to rotate, and realizes the adjustment of the angle of attack of the virtual hydrofoil generating device 3. The sweep angle control housing 4-4 is installed on the angle of attack control housing 4-1, and the angle of attack control housing 4-1 can rotate relative to the sweep angle control housing 4-4. The connecting gear 4-5 and the sweep angle control gear 4-7 are both installed in the sweep angle control housing 4-4, and the connecting gear 4-5 meshes with the sweep angle control gear 4-7. The lower part of the connecting gear 4-5 is welded to the angle of attack control housing 4-1. The sweep angle control motor assembly 4-6 provides torque for the sweep angle control gear 4-7, drives the connecting gear 4-5 to rotate. While the connecting gear 4-5 rotates, it drives the angle of attack control housing 4-1 to rotate. While the angle of attack control housing 4-1 rotates, it drives the entire virtual hydrofoil generating device 3 to rotate, so as to realize the adjustment of the sweep angle.

[0033] In the embodiment of the present application, the virtual hydrofoil control device 4 realizes the adjustment of the angle of attack and sweep angle of the virtual hydrofoil through motor drive and gear transmission, ensures the navigation stability of the vehicle under different hydrological conditions, and always maintains the optimal sweep angle at different speeds. In addition, by differentially adjusting the sweep angles of the virtual hydrofoils on both sides, the resistances of the virtual hydrofoils on both sides are inconsistent, so as to realize the turning of the amphibious vehicle during water navigation.

[0034] As Figure 6As shown, in a possible embodiment, the virtual hydrofoil control device 4 further includes an acquisition module 5, a wireless signal receiving module 6, and an adaptive control module 7.

The adaptive control module 7 is respectively connected to the angle of attack control motor assembly 4-2 and the sweep angle control motor assembly 4-6. The acquisition module 5 is used to acquire the attitude and speed information of the vehicle. The wireless signal receiving module 6 is used to receive the attitude and speed information of the vehicle. The adaptive control module 7 controls the rotation direction, rotation speed, and rotation time of the angle of attack control motor assembly 4-2 and the sweep angle control motor assembly 4-6 based on the attitude and speed information to adjust the angle of attack and the sweep angle. This system integrates the acquisition module 5, the adaptive control module 7, and the wireless signal receiving module 6, and can realize the adaptive intelligent control of the virtual hydrofoil and the steering control during the vehicle's navigation in water. The adaptive control module 7 closed-loop adjusts the control parameters based on real-time sensor data (attitude, speed) to achieve dynamic optimal control. For example, when sailing at high speed, the angle of attack is automatically reduced and the sweep angle is increased; when sailing at low speed, the angle of attack is increased and the sweep angle is reduced.

[0035] In a possible embodiment, the acquisition module 5 includes an attitude sensor and a speed sensor. The attitude sensor is used to acquire the attitude information of the vehicle; the speed sensor is used to acquire the speed information of the vehicle.

[0036] In a possible embodiment, the attitude sensor, the adaptive control module 7, and the wireless signal receiving module 6 are all arranged inside the virtual hydrofoil control housing.

Setting the electronic devices inside the virtual hydrofoil control housing can effectively extend the service life of the electronic devices.
