The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the analysis device for the explosion safety of the instrument panel, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0053] The embodiment of the present invention provides a method for analyzing the safety of instrument panel explosion. Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a method for analyzing the explosion safety of an instrument panel according to the present invention.

[0054] In this embodiment, the method for analyzing the blasting safety of the instrument panel includes the following steps:

[0055] Step S10: After the target instrument panel undergoes a static blasting test, fragment splash information is collected.

[0056] It should be noted that the executor of this embodiment is a controller, which can be a controller for controlling a static explosion test of a vehicle dashboard, or a server or information processing device installed on an experimental device, or other equipment that can achieve this function, and this embodiment does not limit this.

[0057] It should be understood that the current test method is only to conduct instrument panel explosion tests under various temperature conditions, and then test whether the airbag explodes successfully and effectively protects the occupants, and whether fragments and flying debris that are harmful to the personnel are generated. This can only determine whether the instrument panel will produce fragments and flying debris that are harmful to the personnel when it explodes, and cannot objectively and effectively evaluate the damage value of the splashes to different parts of the human body during the explosion process, and thus cannot effectively guide the adjustment of key parameters of the auxiliary airbag and the instrument panel. After mass production, there may be a situation where it cannot effectively protect the occupants. The solution of this embodiment determines the weight, maximum unit weight and material of the splashes corresponding to each body partition of the occupant based on the collected fragment splash information, and finally analyzes the explosion safety of the instrument panel based on the weight, maximum unit weight and material of the splashes, so that the weight of the splashes and the damage to the occupants can be quantified and analyzed, thereby accurately evaluating the safety of the instrument panel.

[0058] In a specific implementation, the target instrument panel refers to an instrument panel of any model and configuration on any type of vehicle, and this embodiment does not impose any limitation on this.

[0059] It should be noted that the static explosion test refers to the static explosion of the airbag at the passenger seat of the vehicle when the vehicle is not in driving state, and then the splash state of the instrument panel and the passenger instrument panel module is tested. Among them, the static explosion test includes: 1. Low temperature static explosion test (after the cockpit module is stored at -30℃32℃ for 6 hours, the static explosion test is immediately carried out within 120S); 2. Normal temperature static explosion test (after the cockpit module is stored at 2334℃ for 6 hours, the static explosion test is immediately carried out within 120S); 3. High temperature static explosion test (after the cockpit module is stored at 8532℃ for 6 hours, the static explosion test is immediately carried out within 120S).

[0060] It should be understood that the debris splash information refers to the splash collected and collected by each splasher after the static blasting test and the related information such as the weight and material of the fragments.

[0061] Step S20: Determine the total weight of the splashes, the maximum single weight of the splashes, and the material information of the splashes corresponding to each body partition based on the fragment splash information.

[0062] In a specific implementation, the body partition refers to the partition of each body part when the occupant sits on the seat. Specifically, the body partition is an area with an area and position preset by the user, which is not limited in this embodiment. The body partition may be a head area, a chest area, and other areas excluding the head area and the chest area.

[0063] It should be noted that the total weight of the splashes refers to the total weight of the splashes in each body partition, so each body partition corresponds to its own total weight of splashes. The maximum single weight of the splashes refers to the weight of the heaviest fragments of all the splashes in each body partition, and each body partition corresponds to its own maximum single weight of splashes. The splash material information refers to the relevant information on the material type of the splashes in each body partition. The specific splash material can be: metal, hard plastic, soft splashes (foam, skin), etc.

[0064] It should be understood that determining the total weight of the splashes, the maximum single weight of the splashes and the splash material information corresponding to each body partition based on the fragment splash information means: extracting the total weight of the splashes, the maximum single weight of the splashes and the splash material information corresponding to each body partition based on the fragment splash information.

[0065] Step S30: generating a blasting safety analysis result of the target instrument panel according to the total weight of the spatters, the maximum single weight of the spatters and the material information of the spatters.

[0066] In a specific implementation, the blasting safety analysis results may specifically include the blasting safety conclusion of the target instrument panel, that is, whether the blasting safety of the target instrument panel is safe, and the distribution, weight and material of the splashes in each body partition.

[0067] Furthermore, in order to accurately generate blasting safety analysis results, step S30 includes: determining the type of spatter according to the spatter material information; comparing the type of spatter with a preset dangerous material type to obtain a first comparison result; comparing the total weight of the spatter with a total weight threshold to obtain a second comparison result; comparing the maximum single weight of the spatter with a maximum single weight threshold to obtain a third comparison result; and generating the blasting safety analysis result of the target dashboard based on the first comparison result, the second comparison result and the third comparison result.

[0068] It should be noted that the type of spatter refers to the specific material type of the spatter collected by the spatter collection box corresponding to each body zone after the static explosion test, including but not limited to: metal, hard plastic parts, soft spatter (foam, skin), etc.

[0069] It should be understood that the dangerous material type refers to the type of splashing objects that may cause harm to the occupants and is pre-set by the user. It can generally be set as: metal, hard plastic and other hard splashing objects. The specific setting is made by the user and this embodiment does not impose any restrictions on this.

[0070] In a specific implementation, the splash type is compared with a preset hazardous material type to obtain a first comparison result, which means: querying and matching whether there is a hazardous material type in the splash type, and the result obtained is the first comparison result.

[0071] It should be noted that comparing the total weight of the splashes with the total weight threshold to obtain the second comparison result means: comparing the total weight of the splashes corresponding to each body partition with the total weight threshold respectively, and using the obtained comparison result as the second comparison result, that is, the second comparison result includes the comparison result of the total weight of the splashes of each body partition. The total weight threshold is a value of any size pre-set by the user, and this embodiment does not limit this.

[0072] It should be understood that comparing the maximum single weight of the spatters with the maximum single weight threshold to obtain the third comparison result means: comparing the maximum single weight of the spatters corresponding to each body partition with the maximum single weight threshold, and using the obtained comparison result as the third comparison result, that is, the third comparison result includes the comparison result of the maximum single weight of the spatters of each body partition.

[0073] In a specific implementation, generating the blasting safety analysis result of the target instrument panel based on the first comparison result, the second comparison result and the third comparison result means: determining the blasting safety analysis conclusion of the target instrument panel based on the first comparison result, the second comparison result and the third comparison result, and then generating the blasting safety analysis result based on the blasting safety analysis conclusion.

[0074] In this way, it is possible to accurately judge whether the blasting safety of the target instrument panel is qualified through the first comparison result, the second comparison result and the third comparison result, and then accurately generate the blasting safety analysis result.

[0075] Furthermore, in order to accurately generate a blasting safety analysis result, the blasting safety analysis result of the target instrument panel is generated according to the first comparison result, the second comparison result and the third comparison result, including: when the first comparison result is that the dangerous material type exists in the spatter type, or the second comparison result is that the total weight of the spatter is greater than the total weight threshold, or the third comparison result is that the maximum single weight of the spatter is greater than the single weight maximum threshold, it is determined that the blasting safety of the target instrument panel is unqualified, and a blasting safety analysis result is generated.

[0076] It should be noted that when the first comparison result is that the dangerous material type exists in the splash type, or the second comparison result is that the total weight of the splash is greater than the total weight threshold, or the third comparison result is that the maximum single weight of the splash is greater than the maximum single weight threshold, the blasting safety of the target instrument panel is judged to be unqualified, and the blasting safety analysis result is generated, which means: when any body partition has a dangerous material type in the corresponding splash type in the static blasting test at any temperature, the total weight of the splash in any body partition in the static blasting test at any temperature is greater than the total weight threshold, or the maximum single weight of the splash in any body partition in the static blasting test at any temperature is greater than the maximum single weight threshold, the blasting safety of the target instrument panel is judged to be unqualified, that is, the blasting safety conclusion is unqualified, otherwise it is qualified. Then, the blasting safety analysis result is generated based on the blasting safety conclusion and the fragment splashing information, so that the type and weight of the blasting splash of the target instrument panel can be quantified.

[0077] In this way, it is possible to accurately determine whether the blasting safety of the target dashboard is qualified, so that the blasting safety analysis results can be provided to users accurately and quantitatively, making it convenient for users to improve their products.

[0078] This embodiment collects fragment splash information after the target instrument panel undergoes a static blasting test; determines the total weight of the splashes, the maximum single weight of the splashes, and the splash material information corresponding to each body partition based on the fragment splash information; and generates the blasting safety analysis result of the target instrument panel based on the total weight of the splashes, the maximum single weight of the splashes, and the splash material information. In the above manner, it is possible to determine the weight, maximum single weight, and material of the splashes corresponding to each body partition of the occupant based on the collected fragment splash information, and finally analyze the blasting safety of the instrument panel based on the weight, maximum single weight, and material of the splashes, so that the weight of the splashes and the damage to the occupants can be quantified and analyzed, thereby accurately evaluating the safety of the instrument panel.

[0079] refer to Figure 3 , Figure 3The figure is a flow chart of a second embodiment of a method for analyzing the explosion safety of an instrument panel according to the present invention.

[0080] Based on the first embodiment described above, the method for analyzing the explosion safety of the instrument panel in this embodiment includes, in step S10:

[0081] Step S101: After the target instrument panel is subjected to a static blasting test, the collected image information and collected weight information of the splash collection box corresponding to each body partition are obtained.

[0082] It should be noted that if Figure 4 The figure shows a schematic diagram of the placement of the splash collection box, where area A and area B correspond to two body zones respectively. There may be other arrangements, which are not limited in this embodiment. The SRP, i.e., the R point position of the seat, refers to the pre-set center point of the hips of the simulated passenger when sitting. The splash collection boxes in area A and area B collect splashes in area A and area B respectively. Figure 4 It is only for illustration and does not limit the content of this embodiment.

[0083] It should be understood that the collected image information refers to the image information in each spatter collection box after the spatter is collected. The collected weight information refers to the total weight of the spatter in each spatter collection box after the spatter is collected, and the weight of a single spatter fragment.

[0084] Furthermore, in order to accurately set the splash collection box, before step S101, it also includes: obtaining the occupant's sitting position information; determining each body partition according to the occupant's sitting position information; and determining the splash collection box corresponding to each body partition according to the body partition.

[0085] It should be noted that the occupant's sitting position information refers to the positions of various parts of the body when the occupant sits in the seat in front of the target instrument panel. Specifically, the occupant's body posture when sitting is simulated based on the seat R point.

[0086] It should be understood that determining each body zone based on the occupant's sitting position information means: dividing the occupant's body posture and position in the occupant's sitting position information into regions according to user-preset rules (for example, head, chest and other three zones) to obtain multiple body zones.

[0087] In a specific implementation, determining the splash collection box corresponding to each body partition according to the body partition means: setting a splash collection box corresponding to each body partition according to the body partition. The size and area of ​​the splash collection box can be set based on the body partition, and this embodiment does not limit this.

[0088] In this way, the spatter collection box is set based on the body partition, which makes the collection of spatter more accurate, thereby making the blasting safety analysis of the target dashboard more accurate.

[0089] Step S102: Determine debris splashing information according to the collected image information and the collected weight information.

[0090] In a specific implementation, determining the debris splashing information based on the collected image information and the collected weight information means: determining the total weight of the splashing objects, the maximum single weight of the splashing objects and the material information of the splashing objects corresponding to each body partition respectively based on the collected image information and the collected weight information, and then obtaining the debris splashing information.

[0091] Furthermore, in order to accurately calculate the total weight of the splashes, the maximum single weight of the splashes and the material information of the splashes, the steps of determining the total weight of the splashes, the maximum single weight of the splashes and the material information of the splashes corresponding to each body partition according to the fragment splash information include: determining the collection weight information and the collection image information of the splash collection box corresponding to each body partition according to the fragment splash information; determining the total weight of the splashes according to the collection weight information; determining the material information of the splashes according to the collection image information; determining the maximum single weight of the splashes according to the collection weight information and the collection image information.

[0092] It should be noted that determining the total weight of the spatters according to the collected weight information means: determining the total weight of the spatters in each spatter collecting box according to the spatters collected by each spatter collecting box.

[0093] It should be understood that determining the spatter material information based on the collected image information also refers to: determining the material type of the spatter in each spatter collection box based on image recognition according to the collected image information.

[0094] In a specific implementation, determining the maximum single weight of the spatters based on the collected weight information and the collected image information means: first determining the maximum single weight of the spatters in the collected image information based on image recognition, and then determining the weight of the maximum single weight of the spatters through the collected weight information as the maximum single weight of the spatters.

[0095] In this way, the total weight of the spatter, the maximum single weight of the spatter and the material information of the spatter can be accurately obtained based on the collected weight information and the collected image information, thereby quantifying the collection and calculation of the spatter and making the analysis of the blasting safety of the target dashboard more accurate.

[0096] Furthermore, in order to accurately obtain the maximum single weight of spatters, the step of determining the maximum single weight of spatters according to the collected weight information and the collected image information includes: determining the maximum single weight of spatters in each spatter collection box according to the collected image information and the collected weight information; determining the target weight of the maximum single weight of spatters according to the collected weight information; and obtaining the maximum single weight of spatters according to the target weight.

[0097] It should be noted that determining the maximum single weight of the spatters in each spatter collection box based on the collected image information and the collected weight information means: determining a preset number of alternative spatters with the largest volume among the spatters in each spatter collection box based on the collected image information, and then determining the one with the largest weight among the alternative spatters based on the collected weight information as the maximum single weight spatter.

[0098] In this way, an accurate and fast determination of the maximum unit weight of the splash is achieved.

[0099] This embodiment obtains the collected image information and collected weight information of the spatter collection box corresponding to each body partition after the static blasting test of the target instrument panel; and determines the fragment spatter information according to the collected image information and collected weight information. In this way, it is achieved that the collected image information and collected weight information of the spatter can be accurately obtained by implementing body partitioning and setting the spatter collection box, so as to accurately calculate the total weight of the spatter, the maximum single weight of the spatter and the material information of the spatter, so that the analysis of the blasting safety of the target instrument panel is more comprehensive and accurate.

[0100] In addition, an embodiment of the present invention further proposes a storage medium, on which is stored an analysis program for the safety of instrument panel blasting. When the analysis program for the safety of instrument panel blasting is executed by a processor, the steps of the analysis method for the safety of instrument panel blasting as described above are implemented.

[0101] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0102] Reference Figure 4 , Figure 4 This is a structural block diagram of the first embodiment of the instrument panel explosion safety analysis device of the present invention.
