[0045] The embodiments of the present invention provide a method and apparatus for determining the evaluation index of gap intrusion safety, thereby solving the technical problem of how to reasonably determine the evaluation index of gap intrusion safety.

[0046] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] The gap intrusion safety evaluation index determination method of this embodiment is applied to gaps with a rectangular cross-section, such as... Figure 1 As shown, the method for determining the safety evaluation index for gap intrusion includes:

[0048] Step S1: Obtain the width of the gap;

[0049] Step S2: If the width of the gap is less than a preset threshold, then obtain the depth of the gap;

[0050] Step S3: Determine the intrusion safety evaluation index of the gap based on the width and depth of the gap;

[0051] Among them, an intrusion safety evaluation index less than or equal to zero indicates that the gap's intrusion safety is qualified, while an intrusion safety evaluation index greater than zero indicates that the gap's intrusion safety is unqualified.

[0052] The cross-section of the gap in this embodiment is as follows: Figure 2 As shown, the cross-section of the gap is a rectangular groove. The evaluation criteria for gap intrusion safety were determined based on multiple experiments. In each experiment, a bionic human head model was impacted with the gap at a fixed velocity, and the extent of damage to the bionic human head model after impact was statistically analyzed. Since the human head is approximately circular, a circular bionic human head model was used to simulate the human head, as shown below. Figures 3-9 As shown. To ensure the reliability of the experimental results, the diameter of the bionic human head model used in the experiment should be the average diameter of a human head. Statistical analysis shows that the average diameter of a human head is generally between 15 and 18 cm, therefore the diameter of the bionic human head model used should be between 15 and 18 cm.

[0053] This embodiment, after multiple experiments, found that when the bionic human head model impacts the gap, if the model can contact the bottom of the gap, such as Figures 3-8 As shown, due to the large contact area between the model and the bottom of the gap, the damage to the model is relatively small, and the intrusion safety of the gap should be considered acceptable; if the model cannot reach the bottom of the gap, such as Figure 9 As shown, since the model only contacts both sides of the gap opening, the contact area is small, and the damage to the model is relatively large. Therefore, the gap intrusion safety should be considered unqualified. Thus, the evaluation criterion for gap intrusion safety should be whether the model can contact the bottom of the gap when colliding with it.

[0054] It is understandable that if the width of the gap is equal to the diameter of the model, then when the model collides with the gap, the model will definitely be able to contact the bottom of the gap, such as... Figures 3-5 As shown, the intrusion safety of this gap is definitely up to standard; if the width of the gap is greater than or equal to the diameter of the model, then when the model collides with the gap, the model will definitely be able to contact the bottom of the gap, as shown. Figure 6 As shown, the intrusion safety of this gap is also qualified; if the width of the gap is smaller than the diameter of the model, it can be determined using the formula... To determine the intrusion safety of the gap, B is the intrusion safety evaluation index, and h is the depth of the gap. The preset threshold (i.e., the diameter of the model) is used, and w is the width of the gap; for example... Figure 7 As shown, when the model collides with the gap, it may simultaneously contact both sides and the bottom of the gap opening. At this time, B is exactly 0, therefore B=0 indicates that the intrusion safety of the gap is qualified; as Figure 8 As shown, when the model collides with the gap, it may only contact the bottom of the gap. In this case, B < 0, therefore B < 0 indicates that the gap's intrusion safety is acceptable; as Figure 9 As shown, when the model collides with the gap, it may only be able to contact both sides of the gap opening. In this case, B > 0, so B > 0 means that the gap's intrusion safety is not up to standard.

[0055] Based on the above analysis, when evaluating the intrusion safety of a gap, after obtaining the gap width, if the gap width is greater than or equal to a preset threshold, the gap can be manually judged to be qualified for intrusion safety. Alternatively, the intrusion safety evaluation index can be automatically assigned a value less than or equal to zero. That is, after step S1, the method for determining the gap intrusion safety evaluation index can also include: if the gap width is greater than or equal to a preset threshold, then the intrusion safety evaluation index is determined to be less than or equal to zero; when the intrusion safety evaluation index is less than or equal to zero, the gap is automatically or manually judged to be qualified for intrusion safety; if the gap width is less than a preset threshold, then it can be determined according to the formula... The intrusion safety evaluation index of the gap is calculated. An intrusion safety evaluation index less than or equal to zero indicates that the gap is qualified for intrusion safety, while an intrusion safety evaluation index greater than zero indicates that the gap is unqualified for intrusion safety.

[0056] like Figure 10 As shown, this embodiment also provides a device for determining the safety evaluation index of gap intrusion, applied to gaps with a rectangular cross-section. The device includes:

[0057] The acquisition module is used to obtain the width of the gap;

[0058] The acquisition module is also used to acquire the depth of the gap if the width is less than a preset threshold.

[0059] The determination module is used to determine the intrusion safety evaluation index of the gap based on its width and depth;

[0060] Among them, an intrusion safety evaluation index less than or equal to zero indicates that the gap's intrusion safety is qualified, while an intrusion safety evaluation index greater than zero indicates that the gap's intrusion safety is unqualified.

[0061] Furthermore, the determination module, based on the width and depth, determines the intrusion safety evaluation index of the gap, which may include:

[0062]

[0063] B represents the intrusion security evaluation index, and h represents the depth. is the preset threshold, and w is the width.

[0064] Furthermore, the preset threshold value can be in the range of 15 to 18 cm.

[0065] Furthermore, after the acquisition module obtains the width of the gap, the determination module can also be used for:

[0066] If the width is greater than or equal to the preset threshold, then the intrusion security evaluation index is determined to be less than or equal to zero.
