[0053] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0054] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The main solution of the embodiment of the present application is: obtaining an airbag design scheme, and constructing an airbag area fitting frame based on the airbag design scheme; simulating the airbag deployment path based on the airbag area fitting frame to obtain a rotation contour line; and verifying the airbag design scheme based on the rotation contour line to obtain a verification result.

[0056] Vehicle safety has become an important indicator in the automotive industry, especially with the increasing stringency of safety regulations, C-NCAP, C-IASI and other related standards, the requirements for passenger protection on the front passenger side are also getting higher and higher. In order to meet the stringent regulatory requirements and achieve a higher star safety level, the airbag volume and gas generator energy of the front passenger side airbag have been increased accordingly, which means that the impact on the interior airbag door related to the airbag explosion is greater; and at present, in order to increase the driving range, new energy vehicles are studying how to reduce the wind resistance system of the whole vehicle as much as possible, so the exterior shape tries to lower the front windshield angle as much as possible, thereby reducing the distance between the airbag door and the front windshield, so as to conduct airbag tests, but the safety of the airbag design cannot be guaranteed, resulting in high risks in airbag tests. Therefore, how to effectively reduce the risk of airbag tests is a problem that needs to be solved urgently.

[0057] The present application verifies the airbag design scheme by constructing an airbag area fitting frame according to the airbag design scheme and simulating the airbag deployment path. The airbag design scheme can be verified by simulating the airbag deployment path, which overcomes the technical defect that the safety of the airbag design scheme cannot be guaranteed, resulting in high airbag test risks, ensures the safety of the airbag design scheme, and effectively reduces the airbag test risks.

[0058] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an airbag testing device, etc. The following takes the airbag testing device as an example to illustrate this embodiment and the following embodiments.

[0059] Based on this, the embodiment of the present application provides a method for verifying an airbag. Figure 1 , Figure 1This is a flow chart of the first embodiment of the airbag verification method of the present application.

[0060] In this embodiment, the airbag verification method includes steps S10 to S30:

[0061] Step S10, obtaining an airbag design scheme, and constructing an airbag region fitting frame based on the airbag design scheme.

[0062] It should be noted that the airbag in this embodiment is located at a preset position, such as the passenger seat position, and this embodiment does not impose any specific restrictions on this. This embodiment is described by taking the passenger seat airbag as an example.

[0063] It can be understood that the airbag area fitting frame is a virtual framework constructed according to the airbag design scheme, which is used to simulate the arrangement area and shape of the airbag inside the vehicle. The airbag area fitting frame can be constructed based on information such as the size, shape and position of the airbag design scheme for subsequent simulation and analysis.

[0064] It is worth noting that by constructing the airbag area fitting frame, the deployment process of the airbag inside the vehicle can be simulated more accurately, thereby more accurately evaluating the safety of the airbag design.

[0065] In a feasible implementation, step S20 may include: determining a target position based on the airbag design scheme; determining a target verification section based on the target position; obtaining a structural scheme of the target verification section, and constructing an airbag area fitting frame based on the structural scheme of the target verification section.

[0066] It should be noted that the target position is the most demanding position. Since the front windshield glass transitions to the two side pillars in the Y direction in an arc, the right side of the airbag door weakening line is the most demanding position in space, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the most demanding position.

[0067] It can be understood that the target verification section refers to the Y-section at the most demanding position. The structural scheme of the Y-section includes the inner surface of the front windshield, the upper body assembly of the instrument panel, and the structural scheme of the airbag layout area. The airbag door frame weakened area 1 and the frame weakened area 2 are found through the cross-sectional scheme of the airbag frame. The fitting frame of the airbag door is constructed through the upper surface of the instrument panel body, the inner surface of the airbag frame and the tear lines of the two weakened areas.

[0068] like Figure 3 As shown, Figure 3It is a schematic diagram of the Y-section of the critical position. The structural scheme of the Y-section includes the inner surface of the front windshield, the upper body assembly of the instrument panel, and the structural scheme of the airbag layout area. The airbag door frame weakened area 1 and the frame weakened area 2 are determined according to the structural scheme of the airbag layout area. The airbag area fitting frame is formed by the upper surface of the instrument panel body, the inner surface of the airbag frame and the tear lines of the two weakened areas. The thickness a of the hinge side of the fitting frame is measured, and the fitting frame of the airbag door is moved a distance b in the direction of the frame weakened line 1 to determine the rotation radius c. The rotation contour line is drawn with the rotation point as the center of the circle, and finally the distance d between the rotation contour line and the inner surface of the front windshield is measured.

[0069] Step S20, simulating the airbag deployment path based on the airbag region fitting frame to obtain a rotation contour line.

[0070] It should be noted that the rotation contour line refers to the contour line of the rotating shape formed by the airbag during the deployment process. In the process of simulating the deployment path of the airbag, the dynamic process of the airbag deployment can be obtained by calculating the position and posture of the airbag at different time points, thereby obtaining the rotation contour line. This rotation contour line can reflect the shape change and posture change during the deployment of the airbag, and is one of the important bases for evaluating the safety of the airbag design scheme.

[0071] It can be understood that simulating the deployment path of the airbag refers to simulating the deployment process of the airbag when the vehicle collides within the airbag area fitting frame to obtain the deployment path and shape of the airbag. The rotation contour line refers to the contour line of the rotation path that the airbag passes through from the initial state to the fully deployed state during the simulation process.

[0072] In the specific implementation, by simulating the airbag deployment path, the actual performance of the airbag in the event of a vehicle collision can be more accurately predicted, thereby more accurately evaluating the safety and reliability of the airbag design. At the same time, by obtaining the rotation contour, the deployment process and morphology of the airbag can be more intuitively understood, providing an important reference for subsequent verification work.

[0073] like Figure 4 As shown, Figure 4 This is a schematic diagram of the airbag deployment process. When the vehicle receives a collision signal, the airbag quickly inflates in the dashboard airbag frame and pushes open the airbag door until it is fully inflated to protect the passengers and prevent them from hitting the dashboard and getting injured. After being pushed open at high speed, the airbag door will reverse to the front windshield side of the vehicle, and the angle of the airbag door will be controlled by the hinge area in the direction of airbag deployment.

[0074] Step S30, verifying the airbag design solution based on the rotation contour to obtain a verification result.

[0075] It should be noted that verification refers to the process of evaluating the safety performance and feasibility of the airbag design. By verifying the airbag design based on the rotation contour, the safety and reliability of the airbag in actual use can be more accurately evaluated, so that problems and defects in the design can be discovered and corrected in a timely manner.

[0076] It is understandable that during the verification process, the rotating contour line can be compared and analyzed with the relevant parts inside the vehicle to determine whether the airbag will interfere with or collide with these parts during deployment, thereby evaluating the safety of the airbag design. If the verification results show that there are safety issues with the airbag design, the design can be modified and optimized to improve the safety and reliability of the airbag. At the same time, the verification results can also provide important reference and basis for airbag testing, effectively reducing the risk of airbag testing.

[0077] In a feasible implementation, step S30 may include: obtaining the front windshield position in the airbag design scheme; determining the target distance based on the rotation contour and the front windshield position; and verifying the airbag design scheme according to the target distance to obtain a verification result.

[0078] It should be noted that the target distance refers to the distance between the rotating contour and the inner surface of the front windshield, which is a key parameter for evaluating whether the airbag design is safe. If the target distance is too small, it means that the airbag may collide with the front windshield when it is deployed, which will not only damage the airbag, but also cause secondary injuries to the passengers. Therefore, by determining the target distance, the safety and reliability of the airbag design can be evaluated more accurately.

[0079] It is understandable that the position information of the front windshield can be obtained by measurement or calculation. Then, based on the rotation contour and the position of the front windshield, the target distance is calculated. If the target distance is less than the preset safety threshold, it means that there is a safety hazard in the airbag design scheme, and the design scheme needs to be modified and optimized.

[0080] In a feasible implementation manner, the verification of the airbag design scheme according to the target distance to obtain a verification result includes: comparing the target distance with a preset distance threshold; when the target distance reaches the preset distance threshold, determining that the verification result is a passed verification and the airbag design scheme does not pose a risk; when the target distance does not reach the preset distance threshold, determining that the verification result is a failed verification and the airbag design scheme poses a risk.

[0081] It should be noted that the preset distance threshold needs to be determined based on the hinge in the airbag frame solution. For example, for a general airbag frame solution with a mesh hinge, the preset distance threshold may be 6 mm, that is, the distance between the rotation contour line and the inner surface of the front windshield is d ≥ 6 mm; for a TPO hinge airbag frame solution, the preset distance threshold may be 15 mm, that is, the distance between the rotation contour line and the inner surface of the front windshield is d ≥ 15 mm. This embodiment does not impose any specific restrictions on this.

[0082] It is understandable that if the target distance reaches or exceeds the preset distance threshold, it means that there is no risk in the airbag design and it can be ensured that the airbag will not collide with the front windshield when deployed. At this time, the verification result will be judged as passed, indicating that the airbag design meets the safety performance requirements and can be subsequently produced and tested. If the target distance does not reach the preset distance threshold, it means that there is a risk in the airbag design, which may cause the airbag to collide with the front windshield, thereby damaging the airbag or causing secondary injuries to the passengers. At this time, the verification result will be judged as failed, and the airbag design needs to be modified and optimized to increase the target distance and meet the safety performance requirements.

[0083] The present embodiment provides an airbag verification method. The present embodiment first obtains an airbag design scheme, and constructs an airbag area fitting frame based on the airbag design scheme to facilitate simulation of the airbag deployment path; simulates the airbag deployment path based on the airbag area fitting frame to obtain a rotation contour line, and quickly and accurately locates the rotation contour line; verifies the airbag design scheme based on the rotation contour line to obtain a verification result, thereby ensuring the safety of the airbag design scheme and effectively reducing the risk of airbag testing.

[0084] In summary, this embodiment verifies the airbag design scheme by constructing an airbag area fitting frame according to the airbag design scheme and simulating the airbag deployment path. The airbag design scheme can be verified by simulating the airbag deployment path, which overcomes the technical defect that the safety of the airbag design scheme cannot be guaranteed, resulting in high airbag test risks, ensures the safety of the airbag design scheme, and effectively reduces the airbag test risks.

[0085] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 5 , the step S20 further includes steps S201-S202:

[0086] Step S201, determining a rotation point and a rotation radius based on the airbag area fitting frame.

[0087] It should be noted that the determination of the rotation point and rotation radius is crucial to accurately simulate the deployment path of the airbag. The rotation point is the position where the airbag starts to rotate when it is deployed, while the rotation radius determines the breadth and coverage of the airbag deployment. The accuracy of these two parameters directly affects whether the airbag can effectively protect passengers and avoid collision with the front windshield.

[0088] In a feasible implementation, step S201 may include: determining an airbag weakening line based on the airbag area fitting frame; determining a rotation point according to the airbag weakening line; and determining a rotation radius according to the rotation point and the airbag area fitting frame.

[0089] It should be noted that the airbag weakening line is the weakening fracture line of the frame. The airbag weakening line can be determined by: the airbag frame is offset by 0 to 1 mm as the weakening starting point (based on the weakening equipment of different suppliers) or the normal direction of the inner surface of the airbag door at the starting point is the preliminary weakening line, such as Figure 6 As shown, Figure 6 Schematic diagram of skeleton weakening fracture line.

[0090] It can be understood that the rotation radius refers to the distance between the rotation point and the diagonal point of the airbag frame.

[0091] In a feasible implementation manner, determining the rotation point according to the airbag weakening line includes: determining the thickness of the hinge area in the airbag area fitting frame based on the airbag area fitting frame; determining the moving distance according to the thickness of the hinge side of the airbag area fitting frame; and determining the rotation point according to the weakening line and the moving distance.

[0092] It should be noted that the thickness a of the hinge side of the simulated frame is measured, the moving distance b=2a, and the fitting frame of the airbag door is moved along the direction of the skeleton weakening line 1 by a distance b, thereby determining the rotation point of the rotating airbag frame.

[0093] Step S202 , simulating the airbag deployment path according to the rotation point and the rotation radius to obtain a rotation contour line.

[0094] It should be noted that based on the rotation point and rotation radius, the deployment path of the airbag, that is, the rotation contour line, can be accurately depicted, which can intuitively show the performance of the airbag in an actual collision situation, including key information such as deployment speed, coverage range, and whether it can effectively protect passengers.

[0095] It is understandable that during the simulation process, various practical factors may also be considered, such as vehicle collision speed, collision angle, passenger body size and sitting posture, etc., to ensure the accuracy and reliability of the simulation results.

[0096] In this embodiment, the airbag deployment path is simulated by simulating the rotation point and the rotation radius determined according to the airbag region fitting diagram to obtain the rotation contour line, which can accurately simulate the airbag working process.

[0097] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the airbag verification method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0098] This application also provides an airbag verification device, please refer to Figure 7 , the airbag verification device comprises:

[0100] The simulation module 20 is used to simulate the deployment path of the airbag based on the airbag area fitting frame to obtain a rotation contour line.

[0101] The verification module 30 is used to verify the airbag design solution based on the rotation contour to obtain a verification result.

[0102] The present embodiment provides an airbag verification device. The present embodiment first obtains an airbag design scheme, and constructs an airbag area fitting frame based on the airbag design scheme to facilitate simulation of the airbag deployment path; simulates the airbag deployment path based on the airbag area fitting frame to obtain a rotation contour line, and quickly and accurately locates the rotation contour line; verifies the airbag design scheme based on the rotation contour line to obtain a verification result, thereby ensuring the safety of the airbag design scheme and effectively reducing the risk of airbag testing.

[0103] In summary, this embodiment verifies the airbag design scheme by constructing an airbag area fitting frame according to the airbag design scheme and simulating the airbag deployment path. The airbag design scheme can be verified by simulating the airbag deployment path, which overcomes the technical defect that the safety of the airbag design scheme cannot be guaranteed, resulting in high airbag test risks, ensures the safety of the airbag design scheme, and effectively reduces the airbag test risks.
