Description

Technical Field

[0001] This invention relates to the field of automotive safety technology, and more specifically, to an emergency system for a car submerged in water and a safe car. Background Technology

[0002] Cars are now a common household item, greatly facilitating travel. However, unexpected events often occur while driving, such as improper operation or accidents that cause the car to fall into water. Although there are emergency systems on the domestic car market that can slow down the sinking of a car that has fallen into water or is submerged, they all have shortcomings. They directly control the airbags to make the car float, without considering the car's condition when it is submerged. For example, if the car is overturned or rolls over, directly controlling the airbags to deploy will not ensure the safety of the occupants. Summary of the Invention

[0003] This invention discloses an emergency system and a safe car for vehicles submerged in water. The system is simple in structure and easy to operate, and aims to improve the problem of vehicles being unable to save themselves when they fall into water and the inability of passengers to provide timely self-rescue time.

[0017] When the wading measurement device senses that the car is submerged in water and the rollover device determines that the car is in a horizontal position, the airbags located at all four wheels of the car are deployed first, and then all the airbags at the connection between the front bumper and the headlights and the connection between the rear bumper and the taillights are deployed last.

[0018] When the wading measurement device senses that the car is submerged in water and the rollover device determines that the car is in a rollover state, the airbags located at the front wheels, the connection between the front bumper and the headlights, the roof, the rear wheels, and the connection between the rear bumper and the taillights are deployed in sequence.

[0019] When the water wading measurement device senses that the car is submerged in water and the rollover device determines that the car is in a rollover state, the airbags installed at the two wheels on the side that are submerged in water are first controlled to open.

[0037] Example

[0038] Combination Figures 1 to 6As shown, this embodiment provides a safe car, including an emergency system for the car submerged in water. The emergency system includes a sensing device 30, which includes a wading measurement device 31 and a rollover detection device. The airbags are installed at all wheels, at the connection between the front bumper and the headlights, at the connection between the rear bumper and the taillights, and on the roof of the car.

[0039] The emergency system for vehicles submerged in water, as described herein, is suitable for installation on vehicles and includes a sensing device 30, several airbags, and a control device; wherein,

[0040] The sensing device 30 is electrically connected to the control device and is configured to determine the vehicle's tilt state and wading state.

[0041] The airbag is electrically connected to the control device and is adapted to be installed around and on the top of the vehicle, and is configured to be controlled to be deployed by the control device.

[0042] The control device is configured to control the deployment sequence of the airbags based on the vehicle's tilt state and wading state transmitted by the sensing device 30.

[0043] Combination Figure 2As shown, in this embodiment, the sensing device 30 includes: a wading measurement device 31 and a rollover detection device; wherein, the wading measurement device 31 is electrically connected to the control device and is disposed around, on top and bottom of the vehicle, specifically, it can be disposed in the middle of the wheel hub, at the sunroof and chassis, and of course, the position can be adjusted according to the vehicle model, so that the wading measurement device 31 can detect the wading status of the entire vehicle; the wading measurement device 31 is configured to sense the wading status of the vehicle and send wading status data to the control device; the rollover detection device is electrically connected to the control device and is configured to detect the rollover status of the vehicle. Here, the wading measurement device 31 can use existing water pressure sensors, such as MIK-P300 or MIK-P310 pressure sensors, to measure water pressure levels. The wading status of the vehicle is determined by the magnitude of the water pressure and the combination of water pressure at different locations. For example, if the water pressure sensors on the roof and sides detect water pressure, it can be determined that the top and body of the vehicle are submerged; if the water pressure sensors on the bottom and front of the vehicle detect water pressure, it can be determined that the front of the vehicle is submerged. The water pressure sensor is electrically connected to a control device, which is an existing technology product, such as a control circuit board or a control computer. This device can judge the water pressure signal transmitted from the water pressure sensor to determine the vehicle's wading depth. It can also combine the judgment of the vehicle's wading status and rollover status sent by the rollover device and the wading measurement device 31; and determine whether the airbags are deployed and the order of deployment. The data from the wading measurement device 31 is used to determine whether the airbags are deployed and which airbags are deployed, while the data from the rollover device is used to determine the order of airbag deployment.

[0044] Combination Figure 6As shown, in another preferred embodiment, the wading measurement device 31 can also be configured as follows: it includes a water storage cavity 311, the bottom of which is pointed and equipped with a weight block 318, or it can be filled with metal; the middle of the water storage cavity 311 is penetrated by a metal tube 316 and fixed to the bottom of the vehicle; a roller bearing 317 is provided at the connection between the metal tube 316 and the water storage cavity 311, and the water storage cavity 311 is configured to rotate around the roller bearing 317 on the metal tube 316, so that the bottom of the vehicle can remain pointed downwards regardless of whether it is overturned or rolled over; a small water inlet 312 is provided near the lower part of the metal tube 316 in the water storage cavity 311 for water to enter the vehicle when it is wet or submerged; and a small water inlet 312 is provided on the upper side of the water storage cavity 311. A large inlet 314 allows for a significant influx of water when the vehicle falls into and is submerged, quickly triggering the anti-sinking system. A drain outlet 313 is located near the upper part of the metal pipe 316, equipped with a check valve. This allows water entering through the small inlet 312 to flow out through the drain outlet 313 in other deep water sections. Due to the flow difference between the small inlet 312 and the drain outlet 313, the flow rate at the drain outlet 313 is greater than that at the small inlet 312, thus preventing the emergency system from reacting. An electrode-type liquefaction switch 319, electrically connected to the control device, is installed inside the water storage chamber 311. When the electrode-type liquefaction switch 319 determines that the chamber is rapidly filling with water, it transmits a signal to the control device, which then determines the water pressure information. Specifically, an artificial drain 315 is provided at the bottom of the water storage chamber 311, so that if the vehicle enters under certain circumstances, the water can be manually drained through the artificial drain 315 to prevent water accumulation or foul odor from the water.

[0045] In this embodiment, the small inlet 312 is the main water intake point when the vehicle is in normal driving or parked condition. When the vehicle is parked and submerged, water accumulation occurs based on the flow rate relationship between the small inlet 312 and the outlet 313. When the water accumulates to the point that it submerges the two electrodes of the electrode-type liquefied switch 319, the emergency system is activated. The dimensions of the outlet 313 and the small inlet 312 can be designed by calculating how long the vehicle needs to be submerged to cause it to malfunction, and by ensuring that the emergency system's activation time due to the flow rate relationship between the outlet 313 and the small inlet 312 is less than the vehicle's malfunction time. The specific design needs to be tailored to the actual vehicle model. The large water inlet 314 is designed to allow a significant amount of water to enter in emergencies such as when the vehicle falls into the water, triggering a rapid response from the emergency system. This requires calculating and comparing the safest escape time for a person with the time required for the emergency system to respond to the water inflow, ensuring that the escape time is less than the emergency system's response time. The size of the large water inlet 314 is then designed based on the actual vehicle model's weight and size. The metal base ensures that the device remains vertically upright regardless of whether it is submerged in water or if the vehicle flips over.

[0046] Combination Figure 2 As shown, the rollover detection device can be installed in various parts of the vehicle or integrated with the wading measurement device to optimize wiring. The rollover detection device includes a fixed plumb bob 321 and an angle sensor. The fixed plumb bob 321 is suspended above a sealed cavity filled with engine oil 322 via a rope 323 (e.g., a nylon rope). The angle sensor is mounted on the rope 323 and electrically connected to the control device to sense the tilt angle and direction of the fixed plumb bob 321 and transmit the data to the control device. When the vehicle rolls over or overturns, the fixed plumb bob 321 tilts at a certain angle. The control device can determine the direction and magnitude of the tilt based on this angle data, thereby determining the vehicle's tilt state. The rollover detection device and the wading measurement device 31 jointly transmit data to the control device, which then controls the airbag deployment sequence according to preset values.

[0047] In another preferred embodiment, the flipping detection device can also directly use a three-axis gyroscope device, which is electrically connected to the control device. The three-axis gyroscope device can measure angular velocity to determine the motion state of the object, thereby determining the tilt state of the car.

[0048] Combination Figures 3 to 5As shown, the airbag includes a first airbag 41 and a second airbag 42. The first airbag 41 is adapted to be installed at the center of the wheel hub 10, the connection between the front bumper and the headlight, and the connection between the rear bumper and the taillight. The second airbag 42 is adapted to be installed on the roof of the vehicle. Both the first airbag 41 and the second airbag 42 include a mounting part 411 with an ignition circuit, an inflation device 413 containing solid fuel, and a waterproof and heat-resistant bladder body 412. The ignition circuit is connected to a control device and is controlled by the control device to ignite. The second airbag 42 is installed on the roof of the vehicle and also includes a front part 421. When the control device determines that the airbag needs to be deployed, it controls the ignition circuit to ignite the solid fuel and generate gas to inflate the bladder body 412, causing the bladder body 412 to quickly pop out and inflate rapidly. The airbag described here is prior art and is well known to those skilled in the art; it will not be described in detail here.

[0049] The working principle of this invention is as follows: when a car falls into water or is submerged in water, the sensing device 30 determines the depth and angle of the car entering the water. By using the combined action of the wading measurement device 31 and the overturning determination device, the wading status and tilt angle of the car body are determined. Then, the control device controls the opening sequence of the airbags that need to be deployed, so that the car roof is facing upward and floats, thus giving the people in the car more time to save themselves.

[0050] The specific working process of this invention is as follows:

[0051] The wading measurement device 31 in the sensing device 30 senses the wading status; simultaneously, the rollover detection device in the sensing device 30 determines whether the vehicle is in a horizontal state, a rollover state, a side rollover state, a head-in-water state, or a tail-in-water state; the control device controls:

[0052] When the wading measurement device 31 senses that the car is submerged in water and the rollover device determines that the car is in a horizontal state, it first controls all the airbags located at the four wheels of the car to be deployed, and finally deploys all the airbags at the connection between the front bumper and the headlights and the connection between the rear bumper and the taillights.

[0053] When the wading measurement device senses that the car is submerged in water and the rollover device determines that the car is in a rollover state, the airbags located at the front wheels, the connection between the front bumper and the headlights, the roof, the rear wheels, and the connection between the rear bumper and the taillights are deployed in sequence.

[0054] When the water wading measurement device 31 senses that the car is submerged in water and the rollover device determines that the car is in a rollover state, the airbags installed at the two wheels on the side that are submerged in water are first controlled to open. When the rollover device detects that the car is in a horizontal state, all the airbags on the other side are opened. Finally, all the airbags at the connection between the front bumper and the headlights and the connection between the rear bumper and the taillights are opened.

[0055] When the wading measurement device 31 senses that the car is submerged in water and the rollover device determines that the car is in a head-down state, the airbag at the connection between the front bumper and the headlights is activated first. When the rollover device detects that the car is in a horizontal state, the airbag at the connection between the rear bumper and the taillights and all the rear wheel airbags are activated.

[0056] When the wading measurement device 31 senses that the car is submerged in water, and the rollover device determines that the car is in a rear-end submerged state, the airbags at the connection between the rear bumper and taillights and the airbags at the rear wheels are activated first. When the rollover device detects that the car is in a level position, all airbags at the connection between the front bumper and headlights and all airbags at the front wheels are then activated.

[0057] By adopting the above technical solution, the present invention can achieve the following technical effects: by setting the sensing device 30 to determine the water wading state and the overturning state of the car, the control device controls the opening sequence of the airbags in different water wading and overturning states, so that the car can be righted and float on the water surface in various overturning states, providing the people in the car with time to save themselves.

[0058] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
