Description

Technical Field

[0001] This invention relates to the fields of automotive safety, energy conservation and emergency escape technology, specifically to an integrated automotive safety system that integrates vehicle cooling, airflow energy recovery power generation, emergency floating in water, underwater propulsion, steering and reversing functions, applicable to various passenger cars and commercial vehicles. Background Technology

[0002] When a car is caught in heavy rain or accidentally falls into water, it is prone to stalling or getting stuck due to wheel slippage, lacking effective emergency propulsion methods, which can easily lead to safety accidents. At the same time, when the vehicle is in normal driving, the high-speed airflow and heat dissipation from the engine compartment are not effectively utilized, resulting in energy waste.

[0003] The existing technology has obvious flaws: Single function: The heat dissipation, power generation and emergency propulsion systems are independent and cannot be integrated. Adding a thruster would significantly increase the vehicle's wind resistance. Flow channel conflict: When sharing an air duct, the heat sink obstructs water flow, resulting in extremely low propulsion efficiency and rendering it unusable; Missing features: No ability to turn or reverse in water, and difficult to escape from dangerous waters on its own after falling into the water; Insufficient automation: Reliance on manual operation leads to delayed response in emergency scenarios.

[0004] To address the aforementioned technical challenges, there is an urgent need for an integrated system that is compact, compatible with various operating conditions, automatically switches between modes, and is safe and reliable, enabling both energy-saving driving and self-rescue from falling into water. Summary of the Invention Purpose of the invention

[0005] This invention aims to overcome the shortcomings of existing technologies and provide an integrated emergency floating cooling and power generation system for automobiles with a variable angle-of-attack turbine. It solves the problems of high wind resistance, energy waste, lack of propulsion when submerged, flow channel conflicts, and single operating conditions. It realizes the integrated functions of cooling and power generation when the vehicle is in motion, emergency propulsion when submerged, steering and reversing in water, and automatic switching of operating conditions, thereby improving vehicle safety and energy utilization. Technical solution

[0006] An integrated emergency floating water cooling and power generation system for automobiles with variable angle of attack turbines includes an air inlet / water inlet / reverse water outlet (1), a main air duct (12), a flow channel switching mechanism (2), a heat sink branch (10), two turbine branches (3), a heat sink (11), a vehicle underbody sub-beam (4), two bottom variable angle of attack turbines (9), two bidirectional power generation drive modules, two bottom air outlets / water spray outlets / reverse water inlets (6), a main control unit, a water level sensor, and a vehicle speed sensor.

[0007] The air inlet / water inlet / reverse water outlet (1) is located at the front of the vehicle and is connected to the main air duct (12) inlet. It has the functions of air intake during driving, water intake during water drop and water outlet during reversing. The air inlet is equipped with a bidirectional flow guide grille and a metal filter screen. The bidirectional flow guide grille guides the airflow / water flow to pass through in one direction to prevent hot air from flowing back during driving. The metal filter screen filters out mud and water plants in the water to avoid blockage of the flow channel and turbine.

[0008] The main air duct (12) is a rigid sealed channel, and the rear end is connected to the flow channel switching mechanism (2). The flow channel switching mechanism (2) adopts an electric flap valve, which consists of a valve plate and a drive motor. It can accurately switch between three flow channel states: driving mode closes the turbine branch, wading forward mode closes the heat dissipation branch, and reversing mode opens the heat dissipation branch.

[0009] The heat sink branch (10) is located directly behind the main air duct and is equipped with heat sinks (11). The heat sink adopts a wide-spacing fin design and is connected to the engine cooling system. When driving, the airflow carries away the heat and realizes engine compartment heat dissipation. When reversing, the water flow is allowed to pass through at a low speed, taking into account both heat dissipation and reversing flow requirements.

[0010] The two turbine branches (3) are symmetrically arranged on both sides of the heat sink branch. The inner wall is smooth to reduce flow resistance, and the outlet leads to both sides of the vehicle bottom sub-beam. The vehicle bottom sub-beam (4) is the original rigid structure of the vehicle and serves as the turbine mounting base to withstand the water spray reaction force without needing to modify the original vehicle structure.

[0011] The two bottom variable angle of attack turbines (9) are symmetrically bolted to both sides of the vehicle bottom sub-beam and connected to the turbine branch outlet respectively. The turbine adopts a gas-liquid dual-purpose fan blade, taking into account the driving characteristics of air and water media. The angle of attack of the fan blade is adjusted by the actuator and can switch between three states: low resistance in the direction of flow (driving and generating electricity), forward angle of attack (spraying water to move forward), and reverse angle of attack (spraying water to reverse).

[0012] Each turbine output shaft is connected to a bidirectional power generation drive module, which uses a permanent magnet synchronous motor. In driving mode, the turbine is driven to rotate by airflow, and the module acts as a generator to convert kinetic energy into electrical energy, which is stored in the battery. In wading mode, the module switches to an electric motor to drive the turbine to rotate and generate propulsion.

[0013] The two bottom air outlets / water spray outlets / reverse water inlets (6) are connected to the turbine outlet and face the rear of the car, serving as exhaust outlets, water spray outlets, and water inlet outlets during reversing.

[0014] The main control unit is integrated into the vehicle's BCM and is connected to the flow channel switching mechanism, turbine angle-of-attack actuator, bidirectional power generation drive module, water level sensor, and vehicle speed sensor. The water level sensor is installed at the lowest point of the chassis, and the vehicle speed sensor collects driving signals. The main control unit has preset control logic: Driving mode: When the water level is <10cm and the vehicle speed is >0, the flow channel switching mechanism closes the turbine branch, the turbine fan blades are adjusted to flow with low resistance, the airflow is cooled by the heat sink, and the turbine generates electricity. Flood warning: When the water level is 10-30cm, the main control unit issues a warning and the turbine fan blades are pre-adjusted to the positive angle of attack; Emergency propulsion: When the water level is >30cm and the engine is off, the flow channel switching mechanism closes the heat dissipation branch, the module drives the turbine to spray water in the forward direction, and differential steering is performed in the water; Reversing mode: Upon receiving a reversing signal, the flow channel switching mechanism opens the cooling branch, the turbine reverses, and water is drawn in from the outlet and sprayed out from the front of the vehicle. Working principle

[0015] Under normal driving conditions for heat dissipation and power generation: The flow channel switching mechanism closes two turbine branches, and the main air duct connects to the heat sink branch; the oncoming airflow enters the main air duct from the air inlet, flows through the heat sink and carries away the heat in the engine compartment, thus achieving heat dissipation; the turbine blades are adjusted to a low-resistance state with the flow direction, the airflow drives the turbine to rotate, the bidirectional power generation drives the module to generate electricity, and the electrical energy supplements the vehicle's power supply; the airflow is finally discharged from the heat dissipation branch outlet, with extremely low wind resistance, which does not affect driving performance.

[0016] Emergency forward movement when submerged in water: When the vehicle stalls in water and the water level exceeds the threshold, the main control unit triggers the emergency mode; the flow channel switching mechanism closes the heat sink branch and connects the main air duct to the turbine branch; water flows into the main air duct from the air inlet and is diverted to the turbine branches on both sides; the turbine blades are adjusted to the positive angle of attack, the module drives the turbine to rotate at high speed, and the water flows out from the outlet to the rear, generating forward thrust; by using the speed difference between the left and right turbines, left or right turns are achieved in the water to avoid obstacles.

[0017] Emergency reversing mode in water: Upon receiving the reversing signal, the main control unit controls the flow channel switching mechanism to open the heat sink branch; the turbine fan blades are adjusted to the reverse angle of attack, and the module drives the turbine to rotate in the reverse direction; water is drawn in from the outlet, passes through the turbine, turbine branch, main air duct, and heat sink branch, overcomes the flow resistance of the wide-spacing heat sink, and is then sprayed forward from the air intake at the front of the vehicle, realizing reversing and escaping the dangerous water area. Beneficial effects

[0018] Multifunctional and integrated: One system integrates five major functions: vehicle cooling, airflow power generation, water propulsion, underwater steering, and reversing, without the need for additional equipment, and has a compact structure; Completely resolves flow channel conflict: The flow channel switching mechanism physically isolates the heat dissipation flow path from the propulsion flow path. The vehicle travels along the heat dissipation branch and wades through water along the turbine branch, avoiding the heat sink from obstructing the water flow and resulting in high propulsion efficiency. Strong adaptability to various operating conditions: Variable angle of attack turbine + bidirectional drive module, adaptable to both air and water media, taking into account multiple operating conditions such as power generation, forward and reverse, and strong emergency response capability; Safe and reliable: Installed on the original vehicle's rigid subframe without altering the original vehicle layout; automatic operating mode switching for rapid emergency response; water steering and reversing capability improves the success rate of self-rescue after falling into the water; Energy-saving and environmentally friendly: It generates electricity by recovering pneumatic energy during vehicle operation, reducing onboard power consumption; it has a simple structure, low mass production cost, and is compatible with various vehicle models, making it highly versatile.

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] As shown in Figure 1, the system of the present invention includes an air inlet / water inlet / reverse water outlet (1) located at the front of the vehicle. The air inlet is connected to the inlet of the main air duct (12). A flow channel switching mechanism (2) is installed at the rear end of the main air duct. A heat sink branch (10) and two symmetrical turbine branches (3) are connected to the rear of the flow channel switching mechanism. Wide-spacing heat sinks (11) are fixed in the heat sink branch. The outlet of the turbine branch leads to both sides of the vehicle underbody sub-beam (4). The vehicle underbody sub-beam is fixed to the vehicle underbody main beam (7). Two bottom variable angle turbines (9) are bolted symmetrically on both sides of the sub-beam and connected to the outlet of the turbine branch. The turbine output shaft is connected to a bidirectional power generation drive module. The turbine outlet is connected to the bottom air outlet / water spray nozzle / reverse water inlet (6). The main control unit is integrated into the vehicle BCM and connects to each actuator and sensor.

[0022] During normal driving, when the vehicle speed is >0 and the chassis water level is <10cm, the main control unit controls the flow channel switching mechanism to close the turbine branch. The airflow passes through the main air duct, the heat sink branch, and the heat sink for heat dissipation. The turbine fan blades are adjusted to flow with low resistance, and the airflow drives the turbine to rotate. The module generates electricity to supplement the vehicle's power supply, and the airflow is discharged from the heat dissipation branch.

[0023] When a vehicle accidentally falls into water, the engine stalls, or the water level in the chassis exceeds 30cm, the main control unit triggers the emergency propulsion mode; the flow channel switching mechanism closes the cooling branch, and water flows through the air intake, main air duct, and turbine branch into the turbine; the turbine fan blades are adjusted to the positive angle of attack, the module drives the turbine to rotate at high speed, and the water is sprayed out from the outlet to provide forward thrust; the speed difference between the left and right turbines is adjusted to achieve steering in the water.

[0024] When reversing is required, the main control unit receives the reversing signal, controls the flow channel switching mechanism to open the heat dissipation branch, adjusts the turbine fan blades to the reverse angle of attack, and the module drives the turbine in reverse; water is drawn in from the outlet, passes through the turbine, turbine branch, main air duct, and heat dissipation branch, passes through the wide-spacing heat dissipation fins at low speed, and is then sprayed forward from the air intake at the front of the vehicle to achieve reversing.

[0025] This invention is not limited to the above-described embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the core technical concept of this invention shall be protected by this invention.
