Description

Technical Field

[0001] This application relates to the field of vehicle safety, and more particularly to a roof rack, a vehicle submersion self-rescue system, and a vehicle. Background Technology

[0002] Vehicle submersion accidents are among the most fatal traffic accidents. After a vehicle falls into the water, the driver and passengers need to evacuate the vehicle and swim to a safe location on their own. The inability to evacuate the vehicle and swim to a safe area in time is the main cause of death.

[0003] Currently, with the development of technology, various technical methods have been developed to address the problem of how drivers and passengers can quickly escape from vehicles, such as rapid window breaking, automatic door opening, and sunroof opening. Furthermore, to give occupants enough time, auxiliary buoyancy devices have been installed on vehicles, such as the universal automotive external body airbag disclosed in CN116653840A. After a vehicle falls into water, the inflated buffer airbag body, the annular airbag body, and the detachable airbag body provide buoyancy, allowing the vehicle to float on the water's surface. Adding auxiliary buoyancy devices to vehicles undoubtedly increases vehicle costs and maintenance difficulty significantly.

[0004] In fact, regardless of where a device is installed on a vehicle to provide sufficient buoyancy for the vehicle and its occupants, the inflated airbag must reach at least 2.5 meters. 3 The volume of the above, which consists of four buoyancy airbags, each 1m long and 0.6m in diameter, presents significant challenges in both inflation and maintenance.

[0005] For example, CN 108725364A also discloses an airbag device, a roof rack device, and a vehicle. The airbag device, installed on the roof rack, allows the car to float on water, reducing the difficulty of escape for occupants and increasing escape time and the chances of survival. However, with the airbag deployed on the roof and the vehicle below it, it's impossible for the vehicle to float on water using the airbag's buoyancy. Furthermore, to provide greater buoyancy, the deployed airbag covers a large area of ​​water, which also hinders the driver and passengers' ability to escape smoothly.

[0006] After a vehicle falls into the water, the driver and passengers cannot swim and therefore cannot reach a safe area, which is a technical problem that is difficult to solve with current technology. Furthermore, the inability of rescuers to accurately locate the vehicle's position after it falls into the water is another challenge, making it difficult to locate and salvage the vehicle in a timely manner. Summary of the Invention

[0007] The purpose of this invention is to provide a vehicle roof rack, a vehicle submersion self-rescue system, and a vehicle, to solve the problems of difficulty in rescuing non-swimmers after a vehicle falls into water, the inability to accurately locate the submersion area, and the inconvenience of rescue and retrieval.

[0065] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, not all of them.

[0067] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0068] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0069] like Figure 1-6 As shown, this invention discloses a vehicle roof rack, including a roof rack body 1 and a rescue airbag device disposed within the roof rack body 1. The rescue airbag device includes a plurality of airbags and buoys that deploy with the airbags; the rescue airbag device is used to keep the driver and passengers afloat on the water surface, and the volume of a single airbag after inflation does not exceed 0.05m³. 3 Its relatively small size and water coverage area will not hinder occupants from surfacing after exiting the vehicle. The number of rescue airbags is determined by the total number of occupants in the vehicle; for example, a five-seat vehicle can be equipped with a maximum of five airbags.

[0070] In scenarios such as off-road driving, stream tracing, river crossing, bridge crossing, flooding, and heavy rain flooding, vehicles and occupants are at risk of falling into the water. Occupants without swimming skills are prone to drowning. This invention addresses this risk by deploying rescue airbags within the vehicle's roof rack after the vehicle falls into water, providing life support to occupants and preventing drowning. Simultaneously, its internal positioning buoys indicate the vehicle's location after it falls into the water, facilitating subsequent retrieval. Figure 10As shown. This invention is integrated into the roof rack of the vehicle, without any external attachments, and has no impact on the vehicle's styling or overall appearance; the overall device has a simple structure, strong applicability, and plays a significant role in protecting the lives of occupants after they fall into the water.

[0071] Example 1

[0072] like Figure 1-6 As shown, the luggage rack body 1 includes a receiving cavity 101, a pop-out window 102, a decorative cover 103, and a limiting rope 104; the receiving cavity 101 is used to receive the rescue airbag device;

[0073] The pop-up window 102 is located in the middle of the luggage rack body 1, and is positioned on the outer side and top of the luggage rack body 1. The position of the pop-up window 102 avoids the connection areas between the two ends of the luggage rack and the vehicle body, and does not affect the installation of the luggage rack. When popped up, the emergency airbag device pops out along the upper side of the luggage rack body, without affecting the opening of the doors or windows.

[0074] The decorative cover 103 covers the pop-up window 102 and encloses the rescue airbag device in the receiving cavity 101; the decorative cover 103 can be connected to the pop-up window 102 by means of adhesive or other methods, and sealant is applied to the connection.

[0075] To ensure safer deployment of the airbag, a limiting rope 104 connects the decorative cover 103 and the luggage rack body 1. When the airbag deploys from the deployment window 102, the decorative cover 103, limited by the limiting rope 104, does not extend beyond the outer edge of the roof. This prevents the deployment range of the decorative cover 103 from affecting the driver and passengers. The decorative cover 103 has an L-shaped structure, and its outer surface facing the driver and passengers is smooth. During deployment, if... Figure 5 As shown, when the limiting rope 104 is at its maximum length, it is pulled in the opposite direction, and the airbag of the rescue airbag device floats upward from the space between the decorative cover 103 and the pop-up window 102 under the action of buoyancy, so as to avoid affecting the driver and passengers from getting out of the vehicle during the inflation and rising phase of the airbag.

[0076] Example 2

[0077] The luggage rack body 1 includes a receiving cavity 101, a pop-out window 102, a decorative cover 103, and a limiting rope 104; the receiving cavity 101 is used to receive the rescue airbag device.

[0078] Regarding the detailed structure of the luggage rack body 1, the decorative cover 103 includes a first connecting plate 1032, a second connecting plate 1033, and an arc-shaped transition plate 1034. The first connecting plate 1032 is connected to the side of the luggage rack body 1 and is flush with the side of the luggage rack body 1. The second connecting plate 1033 is connected to the top of the luggage rack body 1 and is flush with the top of the luggage rack body 1. The arc-shaped transition plate 1034 is fixed between the first connecting plate 1032 and the second connecting plate 1033. One side of the first fastening edge 1031 is connected to the first connecting plate 1032, and the other side is bent and folded into the bottom of the luggage rack body 1. The decorative cover 103 can be integrally molded, and the arc-shaped transition plate 1034 has an elastic force that brings the first connecting plate 1032 and the second connecting plate 1033 close to each other; thus, during assembly, the second connecting plate 1033 first fits against the top surface of the pop-up window 102, and the first fastening edge 1031 is fastened and pressed against the lower side of the pop-up window 102 under the action of the elastic force, and the gap is then glued together with adhesive.

[0079] To facilitate fixing and prevent incorrect installation, the bottom of the luggage rack body 1 is also provided with a second fastening edge 105; the first fastening edge 1031 and the second fastening edge 105 are arranged opposite each other on the bottom sides of the luggage rack body 1, and the bottom of the luggage rack body 1, which is close to the inner side of the second fastening edge 105, is also provided with a positioning groove 107; the first fastening edge 1031, the second fastening edge 105 and the positioning groove 107 are arranged in parallel as long strips. The installation and fixing structure of the vehicle roof luggage rack body 1 is designed so that the pop-out window 102 and the decorative cover 103 must be on the outer side to accurately engage with the second fastening edge 105 and the positioning groove 107, thereby completing the fixing of the luggage rack body 1.

[0080] In order to ensure that the rescue airbag device can be deployed effectively, the material strength of the decorative cover 103 is less than that of the luggage rack body 1; in order to avoid damaging the airbag and the connecting rope, the edge connecting the luggage rack body 1 and the decorative cover 103 is a blunt edge 106.

[0081] The luggage rack body 1 of this invention integrates a self-rescue device and also functions as a retrofit luggage rack. The airbag deployment area is locally weakened and cannot be obstructed, and the structure of the retrofit luggage rack installation area is strengthened to meet retrofit requirements.

[0082] Example 3

[0083] like Figure 9As shown, this application discloses a vehicle submerged in water self-rescue system. The system includes a vehicle roof rack with the structure described above; it also includes a controller, a water level sensor 3, a water pressure sensor 4, and a manual switch 5. The controller is connected to the rescue airbag device and is used to trigger the inflatable rescue airbag device. The water level sensor 3 is electrically connected to the controller and is used to detect the water level signal of the vehicle submerged in water. The water pressure sensor 4 is electrically connected to the controller and is used to detect the water pressure signal of the vehicle submerged in water. The manual switch 5 is electrically connected to the controller and is used to manually send a signal to activate the controller.

[0084] like Figure 9 As shown, the controller can be a PLC or an electronic control module integrated into the vehicle system. The water level sensor 3, the water pressure sensor 4, and the manual switch 5, or any combination thereof, serve as trigger electrical signals. After receiving the signal, the controller activates the corresponding control valve of the rescue airbag device to inflate the airbag and enable the airbag to pop out from the preset position of the luggage rack body 1.

[0085] For example, the water level sensor 3 and the water pressure sensor 4 can be arranged sequentially from top to bottom along the height direction. A conceivable combination is that when the water level sensor 3 detects the vehicle has fallen into the water and the water pressure sensor 4 detects a water pressure signal, the working position of the vehicle's self-rescue system can be determined based on the positions of the water level sensor 3 and the water pressure sensor 4. For instance, when the water pressure sensor 4 is in the middle of the vehicle door, the airbag will deploy as soon as the vehicle sinks.

[0086] Example 4

[0087] This application discloses a vehicle submerged in water self-rescue system, the system including the vehicle roof rack with the above-described structure; it also includes a controller, a water level sensor 3, a water pressure sensor 4, and a manual switch 5, as well as a rescue airbag device installed in the vehicle roof rack that can provide buoyancy for the driver and passengers to float on the water surface.

[0088] Specifically, such as Figure 6 As shown, the rescue airbag device includes an airbag assembly 201, a buoy assembly 202, and an inflation assembly 203 for inflating the airbag assembly 201; the airbag assembly 201, the buoy assembly 202, and the inflation assembly 203 are arranged along the length of the receiving cavity 101.

[0089] The airbag assembly 201 includes an airbag 2011, a first connecting rope 2012, and a cutting component 2013;

[0090] The airbag 2011 is positioned within the pop-up window 102; one end of the first connecting rope 2012 is connected to the airbag 2011, and the other end is connected to the luggage rack body 1; the cutting component 2013 is connected to the first connecting rope 2012 and is used to cut the first connecting rope 2012. After the airbag 2011 is fully inflated, it remains connected to the vehicle through the first connecting rope 2012; after the occupant firmly grasps the first connecting rope 2012, the cutting component 2013 (U-shaped blade) is used to cut the first connecting rope 2012, and the driver and passenger float on the water surface under the buoyancy of the rescue airbag.

[0091] The inflation assembly 203 includes an air tank 2031, an inflation line 2034, and an air valve. The air tank 2031 is located outside the area of ​​the pop-up window 102. The inflation line 2034 connects the air tank 2031 and the airbag 2011. The air valve is located on the inflation line 2034 between the air tank 2031 and the airbag 2011, and the air valve is electrically connected to the controller. The air valve includes a pressure limiting valve 2032 and / or a flow limiting valve 2033. The pressure limiting valve automatically ruptures after the airbag 2011 reaches a certain pressure, causing the rescue airbag to separate from the air tank 2031. At this time, the airbag 2011 is kept connected to the vehicle body by the first connecting rope 2012.

[0092] The buoy assembly 202 includes a buoy 2021 and a second connecting rope that fixes the buoy 2021 to the luggage rack body 1. The buoy 2021 is positioned within the pop-up window 102 and outside the airbag 2011. The buoy 2021 is connected to the vehicle to indicate its location in the water, facilitating subsequent retrieval. The buoy 2021 is inflatable and connected to the air tank 2031 via an inflation pipe 2034. A pressure relief valve 2032 is also provided on the inflation pipe 2034. After the buoy 2021 detaches from the air tank 2031, it is connected to the vehicle body via the second connecting rope.

[0093] Example 5

[0094] like Figure 7 and Figure 8 As shown, this application discloses a vehicle, including a vehicle body 6, and the aforementioned vehicle water rescue system; the vehicle body 6 includes a side frame 601 and a roof 602; the manual switch 5 is disposed inside a handle cover 6021 located inside the roof 602; as shown Figure 7 As shown; the manual switch 5 can also be directly connected to the air valve, thus setting up two independent control systems; under automatic control, the water level sensor and water pressure sensor are connected in parallel to obtain the vehicle water entry signal. When the signal exceeds the calibration value, the controller converts the obtained signal into a start signal to control the air valve to open; under manual control, as long as the driver and passengers pull the manual switch 5, the air valve will open.

[0095] The water level sensor 3 and water pressure sensor 4 are arranged sequentially from top to bottom along the side frame 601, such as... Figure 8 As shown, water pressure sensor 4 is located near the bottom of the door, and water level sensor 3 is located near the upper middle part of the door. When the water level submerges water pressure sensor 4 and / or water level sensor 3, the control receives a signal and controls airbag 2011 and buoy 2021 to inflate and deploy from pop-up window 102. Figure 10 As shown, the rescue airbags inside the vehicle's roof rack deploy to provide life support for the driver and passengers, preventing drowning accidents. Passengers can use the buoyancy of the airbags to float on the surface of the water while awaiting rescue, or they can use a blade to cut the connecting rope and water slide to a safe area. Additionally, the internal locating buoys can indicate the vehicle's location after it falls into the water, facilitating subsequent retrieval.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
