Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an airbag device, an airbag control method, and a vehicle. Background Technology

[0002] To prevent passengers from being ejected from their seats and injured in secondary collisions during severe collisions or rollovers, airbags are typically installed in vehicles to protect their safety. When a collision occurs, the airbag inflates rapidly and deploys instantly, providing a cushioning effect and reducing injuries to passengers from the impact.

[0003] In related technologies, airbag devices are typically installed inside the steering wheel of a vehicle. When a collision occurs, the airbag deploys rapidly from inside the steering wheel to protect the front of the passenger's head. However, when the seats in the vehicle are reclined or tilted at a large angle, and the passenger is lying down, this type of airbag cannot provide sufficient protection for the passenger's body, resulting in lower safety. Summary of the Invention

[0004] In view of this, this application provides an airbag device, an airbag control method, and a vehicle that can ensure better protection for passengers even when they are in a reclining position, resulting in higher safety.

[0005] In a first aspect, embodiments of this application provide an airbag device, the airbag device including a gas generator, a first airbag bag, and a second airbag bag;

[0006] The gas generator is adapted to be fixed inside the seat;

[0007] The first airbag is connected to the gas generator and the second airbag respectively, and the end of the second airbag away from the first airbag is closed and connected to the seat.

[0008] When the vehicle is driving safely, both the first and second airbags are folded and located inside the seat. When the vehicle collides, the gas generator inflates the first airbag, and both the first and second airbags are inflated and ejected outside the seat. The first airbag is located to the side of the seat, and the second airbag is located in front of the seat at a predetermined angle to the width of the seat.

[0009] Optionally, the first end of the second airbag is connected to the first airbag, the second end of the second airbag is closed and connected to the seat, and the first end and the second end of the second airbag are located on opposite sides of the seat.

[0010] Optionally, the first airbag is located on the side of the headrest of the seat.

[0011] Optionally, the second airbag extends along the upper edge of the seat.

[0012] Optionally, the airbag device further includes a first pull strap, one end of which is fixed to the seat and the other end is connected to the second end of the second airbag bag. The first pull strap and the first airbag bag are located on opposite sides of the seat.

[0013] Optionally, the airbag device further includes a second strap, one end of which is fixed to the seat and the other end is connected to the first airbag bag.

[0014] Secondly, embodiments of this application also provide a method for controlling an airbag, the method being applied to the airbag device described in any of the first aspects above, the method comprising:

[0015] Determine the vehicle's current collision level based on the collision intensity;

[0016] In response to the current collision level being greater than a preset level, the current tilt angle of the seat is obtained;

[0017] In response to the current tilt angle being greater than a preset angle, an inflation command is generated, wherein the inflation command is used to instruct the gas generator to inflate the first airbag.

[0018] Optionally, the step of obtaining the current tilt angle of the seat in response to the current collision level being greater than a preset level includes:

[0019] In response to the current collision level being greater than a preset level, the seat pressure is obtained;

[0020] When the seat pressure is greater than a preset pressure, the current tilt angle of the seat is obtained.

[0021] Optionally, the step of obtaining the current tilt angle of the seat in response to the current collision level being greater than a preset level includes:

[0022] In response to the current collision level being greater than a preset level, a target image is acquired, wherein the target image is obtained by capturing the area where the seat is located;

[0023] Based on the target image, seating information is determined, wherein the seating information indicates whether a passenger is seated or not.

[0024] In response to the seating information indicating that a passenger has taken a seat, the current tilt angle of the seat is obtained.

[0025] Thirdly, embodiments of this application also provide a vehicle that includes the airbag device described in any one of the first aspects above.

[0026] The airbag device provided in this application includes a gas generator, a first airbag bag, and a second airbag bag. When a vehicle collision occurs, the gas generator inflates the first airbag bag. Since the first and second airbag bags are connected, gas can also enter the second airbag bag. At this time, the first and second airbag bags are in the inflation device and can deploy outside the seat. Because the first airbag bag is located on the side of the seat, it can protect the side of the passenger. Simultaneously, because the second airbag bag is located in front of the seat and forms a preset angle with the width of the seat, it can protect the front of the passenger's body and prevent the passenger from sliding on the seat. In other words, the airbag device provided in this application can provide all-around protection for the passenger's side and front. That is, even when the passenger is in a reclining position on the seat, the airbag device provided in this application can still stably restrain the passenger on the seat, enhancing the protection of the passenger's body and providing a high level of safety.

[0048] Combination Figure 1 , Figure 2 and Figure 6 As shown, in a first aspect, embodiments of this application provide an airbag device, which includes a gas generator 100, a first airbag bag 200, and a second airbag bag 300.

[0049] The gas generator 100 is adapted to be fixed within the seat 400. In some embodiments, a frame 420 is installed in the seat, and the gas generator 100 can be fixed to the frame 420 by a mounting bracket, thereby allowing the gas generator 100 to be installed more securely and preventing the gas generator 100 from detaching from the seat 400.

[0050] The first airbag 200 is connected to both the gas generator 100 and the second airbag 300. The end of the second airbag 300 furthest from the first airbag 200 is closed and connected to the seat 400. This arrangement ensures that gas from the first airbag 200 can enter the second airbag 300 while preventing gas leakage from the second airbag 300, thus ensuring the effectiveness of subsequent inflation by the gas generator 100.

[0051] When the vehicle is driving safely, both the first airbag 200 and the second airbag 300 are folded and located within the seat 400. In the event of a collision, the gas generator 100 inflates the first airbag 200, causing both airbags 200 and 300 to deploy outside the seat 400. The first airbag 200 is positioned to the side of the seat 400, and the second airbag 300 is positioned in front of the seat 400 at a predetermined angle to its width. Inflating the first airbag 200 involves the gas generator 100 performing an operation based on an inflation command, such as ignition, to ignite the solid fuel within the first airbag 200. This solid fuel generates a large amount of gas, which rapidly fills both the first airbag 200 and the connected second airbag 300.

[0052] Using the airbag device provided in this application embodiment, when a vehicle collision occurs, the first airbag 200 and the second airbag 300 are inflated. Since the first airbag 200 is located to the side of the seat 400, it can protect the side of the passenger 700 on the seat 400. Simultaneously, since the second airbag 300 is located in front of the seat 400 and forms a preset angle with the width direction of the seat 400, it can protect the front of the passenger 700's body and prevent the passenger 700 from slipping on the seat 400. In other words, using the airbag device provided in this application embodiment, the passenger 700's body can be protected from both sides and the front. That is, even when the passenger 700 is in a reclining position on the seat 400, the airbag device provided in this application embodiment can still stably restrain the passenger 700 on the seat 400, enhancing the protection of the passenger 700's body and providing a high level of safety.

[0053] The following is in conjunction with the appendix Figures 1 to 6 The details and functions of the airbag device provided in the embodiments of this application will be described in more specific and detailed manner.

[0054] like Figure 4As shown, in some embodiments, the first end of the second airbag 300 communicates with the first airbag 200, and the second end of the second airbag 300 is closed and connected to the seat 400. It should be noted that the second end of the second airbag 300 can be connected to the frame 420 within the seat 400. The first end and the second end of the second airbag 300 are located on opposite sides of the seat 400. It can be understood that since the two ends of the second airbag 300 are located on opposite sides of the seat 400, for example, the first end of the second airbag 300 can be located on the right side of the seat 400, and the second end of the second airbag 300 can be located on the left side of the seat 400. This configuration allows the second airbag 300 to extend across the width of the seat 400. Since the passenger 700 typically sits on the seat 400, when the second airbag 300 deploys, it ensures that the airbag 300 can effectively restrain the passenger 700's body, thus better securing the passenger to the seat 400. This provides better protection for the passenger 700 in the event of a collision, improving their personal safety.

[0055] like Figure 3 As shown, in some embodiments, the first airbag 200 is located to the side of the headrest 410 of the seat 400. This arrangement ensures that when the first airbag 200 deploys from the seat 400, it is positioned directly to the side of the passenger 700's head, thus providing better protection for the passenger 700's head and preventing head injury.

[0056] like Figure 5 As shown, in some embodiments, the airbag device further includes a third airbag bag 800, which is installed inside the seat 400. One end of the third airbag bag 800 is connected to the gas generator 100, and the other end is closed. When the vehicle is driving safely, the third airbag bag 800 is folded and located inside the seat 400; when a collision occurs, the gas generator 100 inflates the third airbag bag 800, causing it to inflate and deploy outside the seat 400. The third airbag bag 800 is positioned opposite the first airbag bag 200. For example, the first airbag bag 200 is located on the right side of the headrest member 410 of the seat 400, and the third airbag bag 800 is located on the left side of the headrest member 410 of the seat 400. It should be noted that the third airbag 800 works in conjunction with the first airbag 200 to simultaneously restrict the position of the passenger 700's head on both sides, preventing excessive head movement during a vehicle collision, thus further enhancing the protection of the passenger 700 and improving the passenger 700's safety. Figure 5The diagram shown is only a schematic of the first airbag 200 and the third airbag 800. The specific shape of the third airbag 800 can be adjusted as needed to ensure that the third airbag 800 can better protect the head of the passenger 700 when it is inflated.

[0057] like Figure 1 As shown, in some embodiments, the second airbag 300 extends along the upper edge of the seat 400. For example, the second airbag 300 extends along the upper edge of the inner frame 420 of the seat 400. This arrangement allows the second airbag 300 to be better housed within the seat 400 during normal vehicle operation, preventing it from pressing against the front of the seat 400 and thus improving passenger comfort when leaning against it.

[0058] like Figure 3 As shown, in some embodiments, the airbag device further includes a first pull strap 500. One end of the first pull strap 500 is fixed to the seat 400, and the other end is connected to the second end of the second airbag 300. The first pull strap 500 and the first airbag 200 are located on opposite sides of the seat 400. It should be noted that by setting the first pull strap 500, when the first airbag 200 and the second airbag 300 are inflated and ejected from the seat 400, the first pull strap 500 can increase the distance between the second end of the second airbag 300 and the seat 400. This ensures that the first pull strap 500, the second airbag, the first airbag, and the front of the seat 400 can form a sufficient space to accommodate the passenger 700's body. In other words, it ensures that the passenger 700 can be secured, better restraining the passenger 700 on the seat 400 and preventing the passenger 700 from detaching from the seat 400 or slipping on the seat 400 during a vehicle collision, thus improving the safety of the passenger 700.

[0059] like Figure 1As shown, in some embodiments, the airbag device further includes a second pull strap 600, one end of which is fixed to the seat 400, and the other end is connected to the first airbag bag 200. It should be noted that by providing the second pull strap 600, when the first airbag bag 200 is inflated and ejects from the seat 400, the second pull strap 600 can increase the distance between the end of the first airbag bag 200 furthest from the gas generator 100 and the seat 400. This further ensures that the second pull strap 600, the first airbag bag 200, the second airbag bag 300, the first pull strap 500, and the front of the seat 400 can form a sufficient space to accommodate the passenger 700's body. In other words, it ensures that the passenger 700 can be secured, better restraining the passenger 700 on the seat 400 and preventing the passenger 700 from detaching from the seat 400 or slipping on the seat 400 during a vehicle collision, thus improving the passenger 700's safety. It should be understood that the first pull strap 500 and the second pull strap 600 can be fixed to the frame 420 inside the seat by fasteners.

[0060] like Figure 1 As shown, in some embodiments, the end of the first pull strap 500 away from the second airbag 300 can be fixed to the frame 420 inside the seat 400. The end of the second pull strap 600 away from the first airbag 200 can be fixed to the frame 420 inside the seat 400. This can improve the stability of the installation of the first pull strap 500 and the second pull strap 600.

[0061] In some embodiments, the surfaces of the first airbag 200 and the second airbag 300 are corrugated. This increases the friction when the first airbag 200 and the second airbag 300 come into contact with the passenger 700's body, thereby more securely restraining the passenger 700 to the seat 400.

[0062] As can be seen from the above, when the vehicle is in a collision, even if the passenger 700 is in a lying position, the passenger 700 can still be stably restrained on the seat 400, thereby preventing the passenger 700 from leaving the seat 400 or sliding on the seat 400, thus improving the safety of the passenger 700.

[0063] Secondly, combining Figure 7 As shown, this application also provides a method for controlling an airbag, which is applied to the airbag device described in any of the first aspects above. This airbag control method can be executed by a controller on a vehicle. The airbag control method provided in this application includes steps 101 to 103.

[0064] In step 101, the controller determines the vehicle’s current collision level based on the collision intensity.

[0065] Generally, vehicles are equipped with collision sensors that detect the intensity of a collision. In some embodiments, the collision sensors send the detected collision intensity to a controller. The controller determines the vehicle's current collision level corresponding to the collision intensity. The controller pre-stores different collision levels and their corresponding collision intensities.

[0066] In step 102, the controller responds to the current collision level being greater than a preset level by obtaining the current tilt angle of seat 400.

[0067] It should be noted that an angle sensor is installed inside the seat 400. The angle sensor is used to detect the tilt angle of the seat 400, that is, the angle formed by the backrest of the seat 400 and the direction perpendicular to the seat cushion. In some embodiments, the controller sends an angle acquisition command to the angle sensor in response to the current collision level being greater than a preset level. In response to receiving the angle acquisition command, the angle sensor sends the current tilt angle of the seat 400 to the controller.

[0068] In step 103, the controller generates an inflation command in response to the current tilt angle being greater than a preset angle.

[0069] The inflation command instructs the gas generator 100 to inflate the first airbag 200. It should be noted that if the current tilt angle is greater than a preset angle, it indicates that the seat 400 is reclined or tilted at a large angle, and the passenger 700 is generally in a lying position. When the gas generator 100 inflates the first airbag 200, the gas can then enter the second airbag 300, ensuring both airbags are inflated and ejected from the seat 400. This restrains the passenger 700 to the seat 400, preventing them from slipping out or sliding, thus providing more comprehensive protection and improving the passenger's safety in the lying position, reducing the risk of injury in a vehicle collision.

[0070] Combination Figure 8 As shown, this application embodiment also provides an airbag control method, which is applied to the airbag device described in any of the first aspects above. This airbag control method can be executed by a controller on a vehicle. The airbag control method provided in this application embodiment includes steps 201 to 207.

[0071] In step 201, the controller determines the vehicle’s current collision level based on the collision intensity.

[0072] It should be noted that step 201 is the same as step 101, so the embodiments of this application will not be described again here.

[0073] In step 202, the controller receives seat pressure 400 in response to the current collision level being greater than the preset level.

[0074] It should be noted that a pressure sensor is typically installed inside the seat 400. This pressure sensor detects the pressure applied to the seat 400 and determines its pressure. The controller can obtain the seat 400 pressure from the pressure sensor if the current collision level exceeds a preset level.

[0075] In step 203, the controller obtains the current tilt angle of the seat 400 when the pressure on the seat 400 is greater than the preset pressure.

[0076] Understandably, when the pressure on seat 400 exceeds the preset pressure value, it indicates that passenger 700 may be seated on seat 400. The current tilt angle of seat 400 is then acquired to inflate the first airbag 200. This prevents the first and second airbags 200 from deploying when no one is seated on seat 400, thus improving the effectiveness of airbag inflation and providing targeted protection for seated passenger 700. Furthermore, it avoids wasting controller processing resources by acquiring the tilt angle of seat 400 when no passenger 700 is seated.

[0077] In step 204, the controller acquires a target image in response to the current collision level being greater than a preset level.

[0078] The target image is captured by photographing the area where seat 400 is located. It should be noted that vehicles are typically equipped with image acquisition devices, such as cameras. These devices are generally pointed towards seat 400 to acquire the target image. It should be understood that the target image includes image information of seat 400 and its surroundings.

[0079] In step 205, the controller determines the seating information based on the target image.

[0080] The seating information indicates whether passenger 700 is seated or not. In some embodiments, the controller stores a face recognition model. The controller inputs the target image into the face recognition model, which then outputs a determination result for the target image. This determination result is the seating information, i.e., whether passenger 700 is seated.

[0081] In step 206, the controller responds to the seating information that a passenger 700 has taken a seat and obtains the current tilt angle of the seat 400.

[0082] It should be noted that, based on the seating information, it is possible to more accurately determine whether a passenger 700 is seated on seat 400, thereby improving the effectiveness of inflating the first airbag 200 and the second airbag 300, as well as the effectiveness of protecting the passenger 700. In other words, this embodiment only obtains the current tilt angle of seat 400 after confirming that a passenger 700 is seated on it, to further confirm whether the passenger 700 is in a reclining position. This avoids deploying the first airbag 200 and the second airbag 300 when no one is seated on seat 400, thus improving the effectiveness of inflating the first airbag 200 and the second airbag 300, and also providing targeted protection for the seated passenger 700. Furthermore, it avoids wasting controller processing resources by still obtaining the tilt angle of seat 400 when no passenger 700 is seated on it.

[0083] It should be noted that steps 202 to 203 are one way for the controller to obtain the current tilt angle of the seat 400 in response to the current collision level being greater than the preset level, and steps 204 to 206 are another way for the controller to obtain the current tilt angle of the seat 400 in response to the current collision level being greater than the preset level. The two methods can be executed separately or simultaneously.

[0084] In step 207, the controller generates an inflation command in response to the current tilt angle being greater than a preset angle.

[0085] The inflation command instructs the gas generator 100 to inflate the first airbag 200. It should be noted that if the current tilt angle is greater than a preset angle, it indicates that the seat 400 is reclined or tilted at a large angle, and the passenger 700 is generally in a lying position. When the gas generator 100 inflates the first airbag 200, the gas can then enter the second airbag 300, ensuring both airbags are inflated and ejected from the seat 400. This restrains the passenger 700 to the seat 400, preventing them from slipping out or sliding, thus providing more comprehensive protection and improving the passenger's safety in the lying position, reducing the risk of injury in a vehicle collision.

[0086] Thirdly, this application also provides a vehicle that includes the airbag device described in any one of the first aspects. It should be noted that the airbag device installed on the vehicle in this application embodiment has the same components and corresponding functions as the airbag device provided in the first aspect of this application embodiment, so these will not be repeated here. When a collision occurs, the first airbag 200 and the second airbag 300 are inflated. Since the first airbag 200 is located on the side of the seat 400, it can protect the side of the passenger 700 on the seat 400. Simultaneously, since the second airbag 300 is located in front of the seat 400 and forms a preset angle with the width direction of the seat 400, the second airbag 300 can protect the front of the passenger 700's body and prevent the passenger 700 from sliding on the seat 400. In other words, even when passenger 700 is in a reclining position on seat 400, the airbag device provided in this application embodiment can still stably restrain passenger 700 on seat 400, enhancing the protection of passenger 700's body and providing higher safety, which in turn improves the safety of the vehicle.
