Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically, to a side airbag, a side airbag control method, a computer device, and a vehicle. Background Technology

[0002] During driving, a vehicle may be hit by a side object, causing damage to the side body. When the side impact is severe, it may also endanger the safety of passengers. Therefore, to ensure the safety of passengers, side airbags are generally installed in the side structure such as the side pillars or doors of the vehicle. When a side impact occurs, the side airbags will deploy to protect the passengers.

[0003] However, due to differences in passengers' height and body shape, the level of protection provided by the side airbags varies. For example, when the side airbags deploy, the arms of larger passengers may be compressed against their chest and abdomen by the airbag, resulting in chest and abdominal injuries, while smaller passengers may not be affected in this way.

[0004] Meanwhile, in the existing testing process for side airbags, experimental dummies are typically used. However, different countries and regions have different requirements for the types of experimental dummies. This can lead to situations where, when using larger dummies, the arms may be compressed against the chest and abdomen by the side airbag, thus affecting the side airbag testing and making it difficult for the experimental results to cover the usage requirements of different countries and regions. Summary of the Invention

[0005] The problem this invention aims to solve is how to improve the protective effect of side airbags and how to ensure that the experimental results of side airbags meet the requirements of different regions.

[0006] To address the aforementioned problems, in a first aspect, the present invention provides a side airbag, comprising a first sheet, a second sheet, a suture, a pull-string control generator, and an airbag generator. The edges of the first sheet and the second sheet are fitted together to form an airbag. The airbag generator is located within the airbag. The surface area of ​​the first sheet is larger than the surface area of ​​the second sheet. A first end of the suture sewn at least a portion of the first sheet so that the surface area of ​​the sewn first sheet matches the surface area of ​​the second sheet. A second end of the suture is connected to the pull-string control generator. The airbag generator is used to inflate the airbag, and the pull-string control generator is used to break the second end of the suture.

[0007] In this invention, the installation position of the side airbag remains unchanged compared to existing technologies, and the first sheet can be set to face inwards. Whether in testing or actual use, when a side collision occurs, the airbag generator will activate to inflate the airbag formed by the first and second sheets, protecting the test dummy or passenger. If the test dummy or passenger is small, or if there is sufficient distance between them and the vehicle side wall, the inflated airbag will provide protection at the arms, but generally will not further compress the chest or abdomen. If the test dummy or passenger is large, or if the distance between them and the vehicle side wall is small, the cable-controlled generator will activate to cut the seam, exposing the area where the first sheet was originally sewn. In other words, under the inflation of the airbag generator, the first sheet will protrude more than the second sheet, and because the cross-sectional profile of the protruding first sheet can be similarly curved, it helps to drive the arms forward, thus preventing the airbag from compressing the chest and abdomen through the arms. Therefore, it can not only more effectively protect passengers in the event of a side collision during actual vehicle operation, but also be applicable to experimental dummies of different specifications during vehicle testing, thereby meeting the relevant requirements of different regions.

[0008] Optionally, the first sheet includes a first region, an extended region, and a second region, wherein the extended region is located between the first region and the second region, and the first end of the stitch passes sequentially through the connection between the first region and the extended region and the connection between the extended region and the second region.

[0009] Optionally, the two ends of the extended area that are connected to the first area and the second area are arranged in a straight line.

[0010] Optionally, the side airbag further includes a deflation structure disposed on the airbag.

[0011] Optionally, the side airbag further includes a control device and a detection device. The control device is electrically connected to the detection device, the cable control generator, and the airbag generator, respectively. The detection device is used to detect detection information corresponding to the load-bearing structure of the vehicle seat. The control device is used to control the cable control generator and / or the airbag generator to operate according to the detection information.

[0012] Secondly, the present invention also provides a side airbag control method, based on the side airbag described above, the method comprising:

[0013] Obtain detection information corresponding to the load-bearing structure of the vehicle seats;

[0014] When the vehicle is involved in a side collision, the airbag generator is activated.

[0015] When the detection information meets the preset conditions, the control wire generator is activated to cause the suture to break.

[0016] In this invention, whether during testing or actual use, when a side collision occurs, the airbag generator will activate to inflate the airbag formed by the first and second sheets, protecting the test dummy or passenger. If the test dummy or passenger is small, or if there is sufficient distance between them and the vehicle side wall, the inflated airbag can provide protection at the arms, but generally will not further compress the chest or abdomen. During driving, detection information corresponding to the load-bearing structure of the vehicle seats can be obtained. If the detection information indicates that the test dummy or passenger is large, or if the distance between them and the vehicle side wall is small, the pull-wire control generator will also activate to cut the seam, exposing the area of ​​the first sheet that was originally sewn. In other words, under the inflation action of the airbag generator, the first sheet will protrude more than the second sheet. Furthermore, since the cross-sectional profile of the protruding first sheet can be similarly curved, it helps to drive the arms forward, thereby preventing the airbag from compressing the chest and abdomen through the arms. Therefore, it can not only more effectively protect passengers in the event of a side collision during actual vehicle operation, but also be applicable to experimental dummies of different specifications during vehicle testing, thereby meeting the relevant requirements of different regions.

[0017] Optionally, the detection information includes the sliding distance of the seat relative to the seat rail; the step of controlling the pull-string control generator to break the stitching when the detection information meets a preset condition includes:

[0018] When the sliding distance is greater than the preset distance, the pull wire control generator is activated to cause the suture to break.

[0019] Optionally, before controlling the airbag generator to activate when the vehicle experiences a side collision, the method further includes:

[0020] Monitor whether the vehicle has been involved in a collision;

[0021] When the vehicle is involved in a collision, it is determined whether the collision is a side impact.

[0022] Thirdly, the present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the side airbag control method described above is implemented.

[0023] Fourthly, the present invention also provides a vehicle including the computer equipment described above and the side airbags described above. Attached Figure Description

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0043] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0044] Figure 1 This diagram illustrates the structure of a side airbag after inflation according to an embodiment of the present invention. The side airbag includes a first sheet 2, a second sheet 3, a suture 5, a suture control generator 6, and an airbag generator 7 (e.g., Figure 4 As shown), the edges of the first sheet 2 and the second sheet 3 are fitted together to form an airbag, and the airbag generator 7 is located inside the airbag. The surface area of ​​the first sheet 2 is larger than the surface area of ​​the second sheet 3, as shown. Figure 2 and Figure 3 As shown, the first end of the stitch 5 sews at least a portion of the first sheet 2 together so that the surface area of ​​the sewn first sheet 2 matches the surface area of ​​the second sheet 3, as shown. Figure 4 The second end of the suture 5 is connected to the pull-line control generator 6, the airbag generator 7 is used to inflate the airbag, and the pull-line control generator 6 is used to break the second end of the suture 5.

[0045] Specifically, the second sheet 3 and the first sheet 2 can be fabric pieces, such as... Figure 1 The two fabric pieces are sewn together around their edges to form the air bladder of the side airbag. Under normal circumstances, combined with... Figure 3 and Figure 5 or Figure 6 The second sheet 3 has the same area as the first sheet 2. When the sewn area participates in the expansion, it combines... Figure 2 and Figure 6 The area of ​​the second sheet 3 is smaller than the area of ​​the first sheet 2. For example... Figure 7 Side airbags can be installed on the seat back. When the side airbags need to deploy, such as... Figure 8 As shown, the side airbag deploys from the seat back to reduce the impact of external collisions on passengers. Since the side airbag expands horizontally and vertically when inflated, to provide comprehensive protection, the center of the inflated airbag should be roughly positioned between the passenger's head (or the vehicle roof) and the seat surface. To meet this requirement, the side airbag is typically installed below shoulder height, roughly at the level corresponding to the passenger's chest and abdomen, when the passenger is seated. The airbag generator 7 contains propellant. When the airbag generator 7 is triggered, the propellant detonates, filling the airbag and causing it to rapidly inflate, protecting the passenger from external impact injuries. Figure 4 or Figure 6 As shown, the airbag generator 7 and the cable control generator 6 are connected and installed at the joint between the second sheet 3 and the first sheet 2. Figure 1 As shown, one side of the airbag equipped with the airbag generator 7 is placed inside the seat away from the side airbag ejection outlet. That is, one side of the side airbag equipped with the airbag generator 7 and the cable control generator 6 is fixed inside the seat, while the other side of the side airbag inflates and ejects from the ejection outlet, thus avoiding contact between the hardware airbag generator 7 and the cable control generator 6 and the passenger, and preventing the side airbag from causing injury to the passenger.

[0046] In this embodiment, the installation position of the side airbag can remain unchanged compared to the prior art, and the first sheet 2 can be set to face inwards, meaning the second sheet 3 is in contact with the passenger, and the first sheet 2 is farther away from the passenger relative to the second sheet 3. Whether in testing or actual use, when a side collision occurs, the airbag generator 7 will activate to inflate the airbag formed by the first sheet 2 and the second sheet 3, protecting the test dummy or passenger. At this time, if the test dummy or passenger is small, or if there is sufficient distance between the test dummy or passenger and the vehicle side wall, the inflated airbag can act on the arms to provide protection, such as... Figure 9 However, it generally will not further compress the chest and abdomen; if the test reveals that the experimental dummy or passenger is large, or that the distance between the experimental dummy or passenger and the vehicle side wall is small, the pull-wire control generator 6 will also activate to cut the stitches 5, thereby exposing the area of ​​the first sheet 2 that was originally sewn. In other words, under the inflation action of the airbag generator 7, the first sheet 2 will protrude more than the second sheet 3. Figure 10As shown, the overall cross-sectional profile of the protruding first sheet 2 can be similar to an arc shape, which helps to drive the arm to swing forward, thereby avoiding the airbag from being squeezed into the chest and abdomen through the arm. Therefore, it can not only more effectively protect passengers in the event of a side collision during actual vehicle operation, but also be applicable to experimental dummies of different specifications during vehicle testing, so that the experimental results meet the relevant usage requirements of different regions.

[0047] In one embodiment of the present invention, such as Figure 2 As shown, the first sheet 2 includes a first region 20, an extended region 21, and a second region 22, wherein the extended region 21 is located between the first region 20 and the second region 22, as... Figure 3 The first end of the suture 5 passes sequentially through the connection between the first region 20 and the extended region 21, and the connection between the extended region 21 and the second region 22.

[0048] Specifically, the first sheet 2 is composed of a first region 20, an extension region 21, and a second region 22. The first region 20 and the second region 22 are respectively connected to the two sides of the extension region 21. The extension region 21 is normally folded and hidden. The two sides of the extension region 21 are sewn together using stitch 5, that is, the side connecting the first region 20 to the extension region 21 and the side connecting the second region 22 to the extension region 21 are sewn together. This allows the extension region 21 to be hidden inside the side airbag under normal conditions and generally does not participate in the inflation of the airbag. Under normal conditions, combined with… Figure 3 and Figure 5 or Figure 6 The second sheet 3 has the same area as the first sheet 2. After the expansion area 21 participates in the expansion, it combines... Figure 2 and Figure 6 The area of ​​the second sheet 3 is smaller than the area of ​​the first sheet 2.

[0049] In this embodiment, whether during testing or actual use, when the passenger or experimental dummy is short, the side airbags are deployed in their normal position. Figure 9 As shown, when the airbags are fully and naturally deployed, viewed from above, the side airbags appear symmetrical. In this state, the side airbags deploy from the seat back, in the following direction: Figure 8In direction D, as shown, due to the passenger's short stature, the gap between the passenger and the door or the passenger and the side pillar is relatively large, providing sufficient space for the side airbag to inflate. This prevents excessive compression of the passenger due to insufficient space, thus avoiding excessive compression of the passenger's arms and preventing injury to the chest and abdomen. The test results also meet the usage requirements of different regions. When the passenger or experimental dummy is tall, triggering the pull-cord control generator 6 causes it to cut the seam 5, releasing the expansion area 21 to participate in the side airbag inflation. Since the combined area of ​​the first area 20, expansion area 21, and second area 22 is larger than the area of ​​the second sheet 3, and the expansion area 21 is longitudinally arranged on the first sheet 2, with one end of the side airbag fixed inside the seat back, the other end of the side airbag will, under the inflation action, produce... Figure 10 As shown, the force in region C is biased towards the location of the second sheet 3, therefore the direction of the side airbag inflation is as follows. Figure 8 The direction E shown will eventually appear as follows: Figure 10 As shown, after the side airbag inflates, the second sheet 3 is closer to the passenger and the first sheet 2 is farther away from the passenger. Therefore, after the side airbag inflates, area C will move from behind the passenger to the passenger's side, and the side airbag will continue to inflate in front of the passenger, fitting against the passenger and passing under the passenger's armpit. Because passengers are tall, the gap between them and the side pillars is small, reducing the space for the side airbag to inflate. However, after the expansion zone 21 is released, firstly, as the side airbag continues to inflate along the passenger's side and under the armpit, it lifts the passenger's naturally placed arm, preventing it from being compressed. During experiments, the dummy's arm will not cause injury to the dummy's chest or abdomen, thus not affecting the test results and ensuring the results meet the usage requirements of different regions. Secondly, the release of the expansion zone 21 increases the volume of the inflated side airbag. With the same amount of inflating gas, the inflation pressure of the side airbag is reduced, decreasing the pressure on the passenger and reducing the potential harm. Furthermore, the release of the expansion zone 21 alters the inflation path and volume of the side airbag. These two factors work together to create an enclosed effect, protecting not only the passenger's sides but also a portion of the passenger's front body, further enhancing the protective area and effectiveness.

[0050] In one embodiment of the present invention, the two opposite ends of the extended area 21 that are connected to the first area 20 and the second area 22 are arranged in a straight line.

[0051] Specifically, such as Figure 2 and Figure 3 As shown, the extension area 21 has a strip-shaped structure, and the two sides where the first area 20 and the second area 22 meet are straight lines. This makes it easier and faster to divide the extension area 21 or to sew the extension area 21 to the first area 20 and the second area 22.

[0052] In one embodiment of the present invention, the side airbag further includes a deflation structure 4, which is disposed on the airbag.

[0053] Specifically, such as Figure 1 or Figure 5 As shown, the venting structure 4 can be a vent hole, which is installed on the airbag and used to release the gas inside the airbag. Specifically, the vent hole is used to slowly release the gas in the airbag to avoid excessive air pressure inside the side airbag and reduce the compressive stress of the side airbag on the passenger.

[0054] In one embodiment of the present invention, the side airbag further includes a control device and a detection device. The control device is electrically connected to the detection device, the cable control generator 6, and the airbag generator 7, respectively. The detection device is used to detect detection information corresponding to the load-bearing structure of the vehicle seat. The control device is used to control the cable control generator 6 and / or the airbag generator 7 to operate according to the detection information.

[0055] Specifically, the detection device can be a position sensor, gravity sensor, distance sensor, or camera equipment, and the seat support can be a passenger or a test dummy. The detection information can be the slide rail information mentioned later, or it can be weight information, image information, or distance information. The detection device uploads or processes the detection information and then uploads it to the control device. The control device controls the airbag generator 7 to work independently based on the detection information, or controls the cable control generator 6 and the airbag generator 7 to work together, so that the side airbag has multiple deployment modes to suit different passenger or dummy types, thereby improving the adaptability and protective effect of the side airbag.

[0056] Figure 11 This diagram illustrates a flow chart of a side airbag control method according to an embodiment of the present invention. Based on the side airbag described above, the side airbag control method includes:

[0057] S1: Obtain detection information corresponding to the load-bearing structure of the vehicle seat.

[0058] Specifically, for example, seat position sensors can be used to collect the seat's position on the seat rails, or distance sensors can be used to directly measure the distance between the seat and the vehicle panel. The pressure exerted on the seat surface can also be measured. This data is then analyzed to identify the passenger's body size based on seat position or pressure. For instance, larger passengers typically sit further back, while smaller passengers usually adjust their seats further forward to reach the brake pedal.

[0059] S2: When the vehicle is involved in a side collision, the airbag generator 7 is activated.

[0060] Specifically, once the vehicle is started, whenever the vehicle expands to the side, the airbag generator 7 in the side airbag will work to generate expanding gas, causing the side airbag to deploy and inflate to protect the passengers.

[0061] S3: When the detection information meets the preset conditions, control the pull wire control generator 6 to operate so that the suture 5 breaks.

[0062] Specifically, for example, when the detected information is the position of the seat on the seat rail, the preset condition is that the seat position exceeds a preset position; for example, when the detected information is the distance between the seat and the vehicle panel, the preset condition is that the measured distance exceeds a preset distance; for example, when the detected information is the pressure borne by the seat, the preset condition is that the pressure borne exceeds a preset pressure; for example, when the detected information is the distance between the seat and the side pillar, the preset condition is that the distance between the seat and the side pillar is less than a preset distance. When the detected information meets the preset conditions, it indicates that the passenger's body size is large or the dummy used in the experiment is large, and the pull-wire control generator 6 needs to be activated.

[0063] In this embodiment, whether during testing or actual use, when the vehicle experiences a side collision, the airbag generator 7 will activate to inflate the airbag formed by the first sheet 2 and the second sheet 3 to protect the test dummy or passenger. At this point, if the experimental dummy or passenger is small, or if there is sufficient distance between the experimental dummy or passenger and the vehicle side wall, the inflated airbag can provide protection at the arms, but generally will not further compress the chest and abdomen. During driving, detection information corresponding to the load-bearing structure of the vehicle seats can be obtained. When the obtained detection information corresponding to the load-bearing structure of the vehicle seats meets the preset conditions, it indicates that the experimental dummy or passenger is large, or that the distance between the experimental dummy or passenger and the vehicle side wall is small. The pull-wire control generator 6 will also activate to cut the seam, thereby exposing the area where the first sheet 2 was originally sewn. In other words, under the inflation action of the airbag generator 7, the first sheet 2 will protrude more than the second sheet 3. And because the cross-sectional contour of the protruding first sheet 2 can be similar to an arc shape, it helps to drive the arms to swing forward, thereby avoiding the airbag compressing the chest and abdomen through the arms. Therefore, it can not only more effectively protect passengers in the event of a side collision during actual vehicle operation, but also be applicable to experimental dummies of different sizes during vehicle testing, thereby meeting the relevant requirements of different areas.

[0064] In one embodiment of the present invention, the detection information includes the sliding distance of the seat relative to the seat slide rail; the step of controlling the pull-line control generator 6 to break the stitch 5 when the detection information meets a preset condition includes:

[0065] When the sliding distance is greater than the preset distance, the pull wire control generator 6 is activated to cause the sewing thread 5 to break.

[0066] Specifically, such as Figure 12 As shown, a calibration line 8 is provided on the seat slide rail 9, and the position information represented by the calibration line 8 is preset position information. For example, the seat position represented by the calibration line 8 can be 20% of the total length of the seat slide rail 9, and the calibration line 8 is located at the end of the seat slide rail 9 closer to the front of the vehicle. Figure 12 The left end of the seat slide rail 9 is considered the starting end, and the right end is the ending end. The starting end is closer to the front of the vehicle, and the ending end is farther from the front. The sliding distance refers to the distance between the seat and the starting end of the seat slide rail. The seat is installed at the starting end, which is generally suitable for smaller passengers. If the adjustment to the right exceeds a certain range, that is, when the sliding distance is greater than the preset distance, it indicates that the passenger is larger. In this case, the pull-line control generator 6 is activated to cut the seam 5 and release the extension area 21.

[0067] In this embodiment, the side airbag control method further includes: when the sliding distance is less than or equal to a preset distance, controlling the cable control generator 6 to not operate.

[0068] In this embodiment, when the sliding distance is less than or equal to a preset distance, it indicates that the dummy or passenger is relatively short. In this case, only a trigger signal is sent to the airbag generator 7, and the side airbag deploys in its normal state. Because the passenger is short, the gap between the passenger and the side pillar is relatively large, which allows the side airbag to fully inflate. The side airbag's compression of the passenger's side after inflating is within a safe range, and will not cause injury to the passenger's chest or abdomen due to compression of the arm. In addition, not raising the passenger's arm is also to reduce the gap between the passenger and the side pillar when the passenger is short, so that the inflated side airbag can provide sufficient support for the passenger and avoid the side airbag not fitting tightly to the passenger, thus weakening the protection of the passenger.

[0069] In one embodiment of the present invention, such as Figure 13 As shown, before the airbag generator 7 is activated when the vehicle experiences a side collision, the side airbag control method further includes:

[0070] Monitor whether the vehicle has been involved in a collision.

[0071] Specifically, when the vehicle starts, is moving, or is stationary, several collision sensors or stress sensors are installed around the vehicle body to detect external collisions or impacts from all around the vehicle.

[0072] When the vehicle is involved in a collision, it is determined whether the collision is a side impact. If the vehicle is not involved in a collision, no protection strategy is executed.

[0073] Specifically, when a vehicle collision occurs, if the stress sensors installed on the side detect an impact force exceeding a preset stress value, the collision is determined to be a side collision. This triggers a signal to the control device, enabling the side airbags to deploy. If the collision is determined to be a frontal collision rather than a side collision, a frontal protection strategy is implemented, i.e., the frontal airbags deploy.

[0074] Figure 14 A schematic diagram of a computer device according to an embodiment of the present invention is shown. The computer device includes a memory 100, a processor 200, and a computer program stored in the memory 100 and executable on the processor 200. When the processor 200 executes the computer program, it implements the side airbag control method described above. The computer device may be the aforementioned control device or controller.

[0075] The computer device in this embodiment of the invention has similar technical effects to the side airbag control method described above, and will not be described in detail here.

[0076] Figure 15 A partial structural schematic diagram of a vehicle according to an embodiment of the present invention is shown. The vehicle includes the computer equipment and the side airbags described above. The computer equipment may be the control device described above. The vehicle may also include a detection device, which may be a position sensor, a pressure sensor, or a camera device, etc. The detection device sends detection information to the computer equipment, and the computer equipment sends a trigger signal to the cable control generator 6 or the airbag generator 7 in the side airbag to control the inflation mode of the side airbag, thereby enabling the side airbag to adapt to different passenger types and provide protection for different types of customers.

[0077] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
