Description

Technical Field

[0001] The utility model particularly relates to a side air bag detonation test device. Background Art

[0002] In order to protect the occupants when the vehicle is hit from the side and the doors and their accessories (such as door trim panels) and their peripheral accessories (such as B-pillar trim panels) are deformed due to force and invade the passenger compartment, airbags are arranged in the passenger compartment. Airbags include side airbags, which are mostly set near the doors of the car seats (such as the front passenger seat and the main driver's seat). Usually, the protective effect of the side airbags on the occupants will be verified in simulation, static detonation test and vehicle test. Among them, simulation refers to simulating the situation of vehicle collision on the computer; static detonation test refers to fixing the car seat alone, placing a dummy on the car seat, and then setting up the door interior panel or a piece of glass on the side of the car seat to roughly simulate the real car, and finally detonating the side airbag on the car seat to preliminarily confirm the deployment posture of the side airbag and the effect of the side airbag (towards the inside and above the car) lifting the dummy's arm; the vehicle test is as the name suggests, and will not be repeated here.

[0003] Based on the above, in the relevant technology, when it is confirmed in the whole vehicle test that the side airbag does not provide good protection for the dummy (for example, the dummy injury curve does not meet expectations), it is necessary to conduct additional trolley tests to optimize the design of the side airbag (for example, the optimization of the package shape and folding method). It is understandable that, depending on the optimization of the side airbag design, the trolley test may need to be repeated several times, that is, the designer may need to repeat the three steps of "S1. Optimize the side airbag according to the results of the most recent trolley test → S2. Conduct a new trolley test → Based on the test results obtained in S2, analyze whether the design of the side airbag can bring the expected protection effect. If the expected protection effect is not achieved, execute S3 → S3. Return to execute S1" to optimize the design of the side airbag.

[0004] Based on the above, in the related technologies, the trolley test for the side airbag often requires the use of a sliding trolley and a slide table that can slide relative to the trolley; in this type of trolley test, the car seat is slidably set on the slide table, and the dummy is placed on the car seat. The side of the car seat on the slide table is arranged with an equivalent structure that can be regarded as the relevant vehicle structure; the equivalent structure is impacted to simulate the vehicle collision situation, so that the deployment posture and arm lifting effect of the side airbag can be observed. In the trolley test, since it is necessary to ensure that the trolley test and the whole vehicle test have acceptable equivalence, the design of the aforementioned slide table, trolley and car seat that can slide relative to each other has important design purposes including: simulating the situation in which the vehicle as a whole and the car seat inside it will undergo a certain displacement due to the impact force after being hit.

[0005] Furthermore, in order to ensure the equivalence of the trolley test and the whole vehicle test, in actual work, before starting the optimization iteration of the side airbag, it is necessary to use the trolley test to reproduce (reproduce again) the whole vehicle test with poor results. This reproduction requires the collection of dummy injury curves, dummy injury evaluation, and comparison of the data obtained from the trolley test with the data obtained from the whole vehicle test. Only after confirming that the two have acceptable equivalence can the optimization iteration of the side airbag begin. Those skilled in the art will verify the whole vehicle test only after completing the optimization iteration of the side airbag in the trolley test. It can be seen that, because the relevant devices of the trolley test are configured to collect dummy injury data (and the dummy injury data also needs to be collected), in the trolley test, the time equivalent to the impact of the vehicle structure is at least the value that can make the dummy reach the peak of injury; this value is regarded as X1, which is mostly about 50-90ms in possible impact scenarios, that is, 50-90ms after the impact begins. It is understandable that, because it is generally impossible to accurately estimate and time the impact to the point where the dummy's injury reaches its peak, the impact time in the trolley test is mostly the time when the dummy's injury reaches its peak and a period of time later. It is also understandable that, based on the existence of the value X1, the trolley test device as a whole is designed based on the need for the trolley to slide a long distance (including the relevant buffer device used to limit the trolley's sliding distance, which is also designed based on this), which also causes the test site of the trolley test to occupy a larger space.

[0006] Based on the above-mentioned process in the related art, the inventor of this case found that:

[0007] ①Since the static detonation test only detonates the side airbags, and does not simulate the effect of related structures invading the passenger compartment when the vehicle is hit, the test conditions of the static detonation test are quite different from the scenario of a full vehicle collision; in terms of confirming the side airbag deployment posture and arm lifting effect before the full vehicle test, the static detonation test can provide limited help. It is understandable that this will indirectly increase the probability of the side airbag's poor protection effect in the full vehicle test, thereby indirectly increasing the probability of multiple subsequent sled tests.

[0008] ②Because the trolley test needs to replicate the whole vehicle test first, and in the trolley test, it is necessary to collect dummy injury-related data, and the trolley needs to slide for a long distance during the test, and the equivalent structure used to simulate the vehicle-related structure also needs a certain impact time, the preparation time for the trolley test is long and the cost is high. Based on this, if there is a test device that can more accurately evaluate the side airbag compared to the static detonation test, then after the whole vehicle test and before the trolley test, or before the whole vehicle test, the test device can be used to evaluate the optimization iteration of the side airbag, and then the whole vehicle test or trolley test can be carried out, so as to indirectly reduce the number of repetitions of the trolley test.

[0009] In other words, if a test device can be designed that can more accurately evaluate the side airbag than the static detonation test, technical personnel in this field can use the test device to evaluate the side airbag before the whole vehicle test and / or after the whole vehicle test and before the trolley test, which can indirectly reduce the number of trolley tests, thereby indirectly saving manpower and material resources and reducing vehicle development costs.

[0057] Embodiment 1

[0058] like Figure 1 and Figure 2 As shown, this embodiment provides a side airbag detonation test device; for the convenience of description, the front, rear, left, right, up, and down directions of the test device are respectively the same as the front, rear, left, right, up, and down directions of the actual vehicle.

[0059] In this embodiment, the test device includes a driving device 1, an seat component 2, a limiting body 3 and a first base 4; wherein the seat component 2 is used to install a vehicle seat with a side airbag (not shown), and is fixedly arranged on the right side of the first base 4; the first base 4 is used to be connected to the B-pillar trim (not shown) and the door trim (not shown), and the first base 4 is configured to be able to collide with the seat component 2 from left to right under the drive of the driving device 1; at the same time, the limiting body 3 is fixedly arranged between the first base 4 and the seat component 2, and is spaced apart from the first base 4 and the seat component 2 respectively; the limiting body 3 blocks the side of the first base 4 to ensure that the first base 4 stops after traveling to a set distance.

[0060] As can be seen from the above, different from the static detonation test in the related art of "fixing the car seat alone on the test site, placing a dummy on the car seat, and then erecting a door trim panel or a piece of glass on the side of the car seat to simulate the real car, and finally detonating the side airbag on the car seat", this embodiment sets a first base 4 on the side of the seat component 2 to install the B-pillar trim and the door trim, and enables the car seat with the dummy to be installed on the seat component 2, so that the test device can simulate the real car scene where the vehicle-related structure is next to the car seat. In this way, by allowing the first base 4 to be driven by the driving device 1, this embodiment can make the first base 4 carry the B-pillar trim and the door trim to collide with the car seat with the dummy, thereby simulating the situation of the vehicle being hit on the side in the whole vehicle test.

[0061] It can be understood that, compared with the static detonation test, the test device provided in this embodiment can undoubtedly simulate a situation that is closer to the whole vehicle test (or the real vehicle collision). Based on this test device, those skilled in the art can use this test device to evaluate the side airbag after the whole vehicle test and before the trolley test, and / or before the whole vehicle test, so as to more accurately simulate the impact of the vehicle-related structure intruding into the passenger compartment on the deployment of the side airbag during the deployment of the side airbag, and effectively evaluate the impact of the deployment of the side airbag on the dummy's arm and the protection range and protection effectiveness of the side airbag; and, according to the evaluation results of the side airbag, after the optimization iteration of the side airbag is completed, the trolley test is carried out, which can also indirectly reduce the number of trolley tests, indirectly save manpower and material resources, and reduce the development cost of the vehicle.

[0062] It should be noted that the above description of "technical personnel in the field may use the test device to evaluate the side airbag after the whole vehicle test and before the trolley test, and / or before the whole vehicle test" specifically means that technical personnel in the field may cancel the static detonation and directly use the test device of this embodiment to verify and evaluate the side airbag, and technical personnel in the field may also use the test device of this embodiment to verify and evaluate the side airbag after the static detonation test. Technical personnel in the field may also use the test device of this embodiment to verify and evaluate the side airbag after the whole vehicle test and before the trolley test, on the premise that the whole vehicle test results are not good and a trolley test is required.

[0063] Furthermore, with respect to the description that “a person skilled in the art may also use the test device to verify and evaluate the side airbag after the vehicle test…”, in order to further illustrate the utility of the test device of this embodiment, a more in-depth comparison is made between the test device provided in this embodiment and the device used in the trolley test:

[0064] The inventor of this case discovered that in the scenario of real vehicle collision or whole vehicle test, when the vehicle is hit, the time from the side airbag being detonated due to the vehicle collision to the time it is deployed to at least a certain extent is recorded as X2, and X2 is a time value much smaller than the aforementioned X1, and is usually around 10ms. After the side airbag is detonated, the side airbag protects the occupant (or dummy) by resisting these related vehicle components, and the peak of this protection effect usually ends before a certain time point; the time required to reach this "certain time point" is recorded as X3. Similarly, the side airbag lifts the occupant's (or dummy's) arms through its own expansion, thereby protecting the occupant (or dummy), and the peak of this protection effect usually ends before reaching time X3. In real vehicle collision or whole vehicle test, X3 is a data that is greater than the aforementioned X2 and significantly smaller than the aforementioned X1, and is usually around 30ms.

[0065] It can be understood from the above that, with the test device provided in this embodiment, those skilled in the art can reproduce the intrusion state from the start of the collision to time X3 during the vehicle side impact test. In addition, it can be understood that when conducting a trolley test or using the test device of this embodiment to conduct a test, those skilled in the art are able to roughly predict the corresponding values ​​of X1, X2 and X3 based on experience and / or simulation data and / or vehicle test results.

[0066] Based on the above, the inventors of this case found that the process that needs to be observed based on the need to iterate the optimization of the side airbag is the process from the side airbag being detonated to the peak of its protective effectiveness. Therefore, the inventors of this case believe that before conducting a trolley test that needs to be strictly benchmarked against a whole vehicle test (that is, it needs to be quite equivalent to a whole vehicle test), due to the high cost and long preparation period of the trolley test, those skilled in the art can use the test device provided in this embodiment to observe only the deployment state of the side airbag and the effect of raising the arm without collecting dummy injury data, and optimize the design of the side airbag until the optimization of the side airbag is completed, and then conduct a trolley test to minimize the number of repetitions of the trolley test, thereby indirectly saving manpower and material resources and reducing the development cost of the vehicle.

[0067] Furthermore, the features of the device commonly used for trolley testing in the related art include at least one of the following ①-③ (in most cases, the device used for trolley testing has the following features ①-③):

[0068] ① The car seat must be slidably arranged in the device system of the trolley test, that is, the parts used to install the car seat mostly include slide rails extending left and right to simulate the movement of the car seat itself along the impact force during the whole vehicle test (or the actual vehicle being hit);

[0069] ② A slide for installing the car seat is required, and the slide is set on a sliding trolley;

[0070] ③ The overall trolley test device is designed based on the need for the trolley to slide a long distance. The buffer device used to limit the sliding distance of the trolley in the trolley test device is also designed based on this, so as to collect the dummy injury curve.

[0071] Since X3 is much smaller than X1, and in this embodiment, the test device used for testing (as described above) does not need to collect dummy injury data, therefore: compared with feature ① of the above-mentioned trolley test device, the test device provided in this embodiment does not require the parts for installing the seats to be slidable; compared with feature ② of the above-mentioned trolley test device, the test device provided in this embodiment does not need to consider the connection relationship between the slide and the vehicle seat, and the connection relationship between the slide and the trolley; compared with feature ③ of the above-mentioned trolley test device, in the test device provided in this embodiment, the first base 4 does not need to slide a long distance, that is, (because there is no need to collect dummy injury curves, therefore) the vehicle parts related to intrusion into the passenger compartment (such as B-pillar trim and door trim) do not need to have the intrusion amount in the whole vehicle test or trolley test, and only a smaller intrusion amount is required so that the test personnel can observe the deployment state of the side airbag and the effect of raising the arm.

[0072] Furthermore, in this embodiment, a limiting body 3 is provided between the first base 4 and the seat component 2. The purpose of providing the limiting body 3 is to prevent the device used to simulate the vehicle structure from excessive movement and excessive intrusion into the dummy. In more detail, since the first base 4, the B-pillar trim and the door trim all have a certain mass, after the driving device 1 stops providing driving force to the first base 4, the first base 4, the B-pillar trim and the door trim will continue to move due to inertia. In order to block this inertial movement, the limiting body 3 is provided in this embodiment. Correspondingly, since the dummy injury curve needs to be collected in the trolley test, and the sliding distance of the trolley in the trolley test is configured to be longer, it is impossible to provide a limiting body 3 between the component used to set the seat and the component used to install (parts related to intrusion into the passenger compartment) in the trolley test.

[0073] Based on the above, in a possible implementation manner, one method of confirming the position of the limiter 3 is that a technician in this field sets the position of the limiter 3 based on experience based on data before the test (such as vehicle test data and / or simulation data and / or static detonation test data).

[0074] In a possible implementation manner, another method for confirming the position of the limiter 3 is: to estimate the value of X3 when the test device of this embodiment is used for testing; to substitute the estimated X3 into the vehicle test data or simulation data, and to reversely estimate the distance that a certain point of the relevant parts of the passenger compartment invaded by the impact during the vehicle test or simulation, and the distance that the point invaded the dummy at the time of (estimated) X3; and then, based on the obtained distance data and in combination with the design of the limiter 3 blocking the movement of the first base 4, the B-pillar trim and the door trim, to estimate the position where the limiter 3 should be located.

[0075] For the above-mentioned side airbag detonation test device, the following is a more detailed exemplary configuration:

[0076] Please continue reading Figure 1 and Figure 2 The test device of this embodiment is used to observe the detonation of the lower airbag under the side collision condition (or to perform the MDB, deformable moving barrier side collision test). The test device also includes a base 5 fixedly set on the ground, the seat component 2 and the limiter 3 are non-slidably set on the base 5 by welding or threaded connection, and the drive device 1 is located on the left side of the first base 4. The first base 4 is connected to the drive device 1 by its left surface, and is slidably set on the base 5. The first base 4 can collide with the seat component 2 from left to right under the drive of the drive device 1.

[0077] Exemplarily, the first base 4 is attached to the driving part of the driving device 1 only on its left surface, that is, the "transmission connection" is limited to the action of the driving device 1 pushing the first base 4 from left to right to hit the seat 2. Exemplarily, the driving device 1 is a servo driving device.

[0078] Based on the above, in a possible implementation manner, in order to adapt to different test scenarios, the seat component 2 and the limiting body 3 can be non-slidably arranged on the base 5 in a detachable manner such as a threaded connection; correspondingly, a plurality of mounting holes (not shown) for mounting the seat component 2 and the limiting body 3 can be arranged on the base 5 in a grid distribution manner, so that the seat component 2 and the limiting body 3 can change their positions on the base 5 by disassembly and then reinstallation.

[0079] Please read further Figure 1 and Figure 2 In order to realize the design that the first base 4 can be slidably set on the base 5, the test device also includes a column 6 and a follower 7. The front and rear ends of the first base 4 are fixedly connected to the follower 7. Each follower 7 is fixedly connected to the end of the first base 4 at one end. In order to restrict the movement direction of the first base 4, each follower 7 also has a part arranged along the left and right direction, and this part can be slidably arranged in the column 6.

[0080] Specifically, the number of columns 6 is two, the number of followers 7 is four, the two columns 6 are fixed to the left and right sides of the reclining seat 2, the front and rear ends of the first base 4 are fixedly connected to the two followers 7, and the column 6 is a rectangular parallelepiped whose length direction is the up-down direction, the follower 7 is an L-shaped body, a part of the follower 7 is extended in the front-to-back direction, and the other part of the follower 7 is extended in the left-to-right direction. In this embodiment, when the follower 7 is assembled with the column 6 and the first base 4, the part of each follower 7 extending in the front-to-back direction is fixedly connected to the end of the first base 4, and the part of each follower 7 extending in the left-to-right direction is penetrated on the column 6 on the same side of the reclining seat 2 as the follower 7, and is slidably connected to the column 6.

[0081] It is understandable that the specific number of the follower 7 and the column 6 is an item that can be flexibly designed by those skilled in the art.

[0082] In addition, in a possible embodiment, the column 6 can be used as follows Figure 3The structure shown in the figure; at this time, skirts 61 are formed by extending from the left surface and the right surface of the column 6 toward the outside of the column 6, and holes 62 are opened on the skirts 61; correspondingly, a plurality of mounting holes (not shown) for mounting the seat member 2 and the limiter 3 are provided in a grid distribution manner on the base 5; in this way, the column 6 can be detachably fixed to the base 5 by passing fixing members such as bolts (not shown) through the holes 62 and the aforementioned mounting holes; at the same time, if necessary, the position of the column 6 on the base 5 can be changed by removing the fixing members and then reinstalling them.

[0083] It is understandable that, in order to ensure the structural stability of the column 6, a reinforcing rib (not shown) integrally formed with the column 6 can be designed between the left and right surfaces of the column 6 and the corresponding skirt 61. The shape design of the reinforcing rib is a flexible setting item for those skilled in the art and will not be described in detail here.

[0084] It is understandable that a slideway (not shown) may be provided below the first base 4, and the first base 4 may be slidably connected to the slideway to achieve the slidable setting of the first base 4. In a possible embodiment, the slideway and the follower 7 may be provided selectively or simultaneously.

[0085] Please return to continue reading Figure 1 and Figure 2 In this embodiment, the first base 4 is a metal product with considerable strength to ensure that the first base 4 can withstand the thrust of the driving device 1 and to simulate the strength of the vehicle door and its surrounding structures as much as possible during the test.

[0086] Furthermore, considering that the first base 4 is a metal product, although the first base 4 can also be used directly as a part to provide a mounting platform for the door trim and the B-pillar trim, if the structure for mounting the door trim and the B-pillar trim is not integrally formed on the first base 4, and the door trim and the B-pillar trim are only fixed on the first base 4 by opening holes and grooves, it will lack equivalence to the door and its nearby structures; and if the imitation real car structure for mounting the door trim and the B-pillar trim is directly integrally formed on the first base 4, it is not a cost-effective option. Therefore, illustratively, the test device also includes a second base 8 fixedly arranged on the right surface of the first base 4, and the second base 8 is a wooden product that is easy to be processed and can be easily made into an imitation shape of a real car door and its nearby sheet metal (such as a B-pillar). In this embodiment, the second base 8 is used as a part to directly provide a mounting platform for the door trim and the B-pillar trim, so that the door trim and the B-pillar trim are indirectly connected to the first base 4.

[0087] More specifically, the second base 8 is detachably fixed to the first base 4 by means such as bolt connection or snap connection, and is provided with an imitation door area 81 and an imitation B-pillar area 82; wherein the imitation door area 81 is an imitation shape of a door, and is used to simulate a door on the first base 4 to install a door trim, and the imitation B-pillar area 82 is an imitation shape of a B-pillar, and is used to simulate a B-pillar on the first base 4 to install a B-pillar trim. In addition, the aforementioned limiting body 3 is located between the second base 8 and the seat component 2, is spaced from the second base 8, and blocks the right side of the second base 8. In a possible embodiment, the second base 8 can be configured so that after it is assembled with the door trim, the lower edge of the door trim is above the lower edge of the second base 8, and the limiting body 3 is configured to collide with the second base 8 at the bottom of the door trim when the second base 8 moves to the right, so as to ensure that the second base 8 will not move too far to the right due to the inertial movement of itself and the first base 4.

[0088] It can also be understood from the above that the connection method between the second base 8 and the door trim and B-pillar trim is the same as the connection method between the relevant structure on the actual vehicle and the door trim and B-pillar trim. Then, when the first base 4, the second base 8, the door trim and the B-pillar trim are assembled, these four can simulate the vehicle door and its surrounding structures; at the same time, the limiter 3 blocks the expected rightward movement trajectory of the second base 8; when the test starts, when the first base 4 is driven by the driving device 1 to hit the vehicle seat, the first base 4 will push the second base 8, so that the door trim and B-pillar trim on it move to the right, thereby simulating the situation where the door trim and B-pillar trim invade the passenger compartment when the actual vehicle is hit from the side.

[0089] It is understandable that the positional relationship between the column 6, the follower 7, the first base 4 and the second base 8 is an item that can be designed specifically and non-creatively by those skilled in the art based on the actual vehicle design parameters and test requirements.

[0090] It is understandable that, for the convenience of manufacturing, installation and replacement, the second base 8 may include a plurality of wooden blocks; by manufacturing and installing these blocks on the first base 4, the second base 8 may be formed on the first base 4. In a possible embodiment, after the first base 4 and the second base 8 are assembled, the physical picture of the two is as follows: Figure 4 For easy viewing, Figure 4 The imitation B-pillar area 82 and the imitation door area 81 are marked.

[0091] Please continue reading Figure 4 In a possible implementation manner, a plurality of assembly holes 41 for mounting the second base 8 on the first base 4 may be provided on the first base 4 so as to fine-tune the position of the second base 8 and improve the versatility of the first base 4 so that the first base 4 can be adaptively assembled with the second base 8 corresponding to the door shapes of different vehicle models.

[0092] Please refer back to Figure 1 and Figure 2 In a possible implementation, the step of using a test device to simulate vehicle intrusion and detonation of a lower side airbag may include:

[0093] S1: The acceleration parameter (or acceleration waveform) generated by an acceleration collection point on the door in the vehicle test or simulation is used as the input curve of the driving device 1; in other words, the acceleration parameter is used as the acceleration parameter when the driving device 1 pushes the first base 4. For example, the acceleration collection point can be set at a position on the door that will intrude into the dummy's chest after being hit.

[0094] S2: Confirm the value of X3, for example, 30ms. Confirm which position on the test device of this embodiment (remember this position as position α) is equivalent to the position of the acceleration collection point in step S1 in the vehicle test.

[0095] S3: Perform mathematical processing (e.g., integration processing, the method of performing mathematical processing on such acceleration parameters is common knowledge of those skilled in the art) on the acceleration parameters in step S1, and obtain the value of the door position corresponding to the acceleration collection point in step S1 intruding into the dummy's chest when the time X3 (e.g., 30 ms) confirmed in S2 is obtained, which is recorded as d (e.g., 100 mm).

[0096] S4: According to d in step S3, the position of the limiter 3 on the base 5 is adjusted to ensure that during the subsequent impact, at 30ms, the value of the position α confirmed in step S2 on the test device intruding the dummy is also approximately d.

[0097] S5: The driving device 1 is operated to push the first base 4 and start timing, and at the same time, a detonation signal for the side airbag is given.

[0098] S6: Observe the deployment status of the side airbag and the effect of raising the arm.

[0099] Of course, in a possible implementation, one method to confirm the position of the limiter 3 is for a technician in this field to set the position of the limiter 3 on the base 5 based on experience, in combination with data before the test (such as vehicle test data and / or simulation data and / or static detonation test data).

[0100] Embodiment 2

[0101] This embodiment also provides a side airbag detonation test device. The test device provided in this embodiment is used to observe the detonation of the side airbag under the side pole working condition (or for performing SIDEPOLE, side pole collision test).

[0102] like Figure 5and Figure 6 As shown, the test device includes a base 5 ( Figure 5 and Figure 6 Not shown), column 6, seat member 2 ( Figure 5 and Figure 6 Not shown), drive device 1 ( Figure 5 and Figure 6 Not shown) and the limiter 3 ( Figure 5 and Figure 6 Not shown), and these five adopt the design of embodiment 1. In addition, the test device also includes a first base 4, and the first base 4 basically adopts the design of embodiment 1 in terms of overall appearance.

[0103] The difference between this embodiment and the first embodiment is that the first base 4 includes an intermediate body 42 and side pieces 43 which are connected and separated from each other, wherein the intermediate body 42 is the part where the first base 4 contacts the driving device 1, and the side pieces 43 are respectively located at the front and rear sides of the intermediate body 42. Before the test begins, or before the driving device 1 applies force to the intermediate body 42, the first base 4 has a flat rectangular appearance. The front side piece 43 of the two side pieces 43 is the front side piece 431, and the rear side piece 43 is the rear side piece 432. The test device of this embodiment also includes a hinge body 9, and the front side piece 431 and the rear side piece 432 are rotatably connected to the intermediate body 42 through the hinge body 9. In a possible implementation manner, the specific structure of the hinge body 9 can refer to the hinge structure of the door.

[0104] As described above, each hinge body 9 has a portion fixed on the side member 43 and a portion fixed on the intermediate body 42; and, in this embodiment, there are two columns 6 arranged at intervals as in the embodiment, one of the two columns 6 is located at the front side of the front side body 431, and the other is located at the rear side of the rear side body 432; at the same time, the two columns 6 are each provided with a connecting unit 10 on themselves, and the test device also includes a follower 7, and the connecting unit 10 is arranged in a one-to-one correspondence with the follower 7, and the front side body 431 and the rear side body 432 are fixedly connected to the follower 7 at their respective ends away from the intermediate body 42.

[0105] In this embodiment, the follower 7 is used to cooperate with the connecting unit 10, connected to the side member 43, and cooperate with the hinge body 9, so that the first base 4 can be Figure 7 As shown, after the driving device 1 applies force to the intermediate body 42, the shape of the intermediate body 42 changes from a flat rectangular parallelepiped to a posture where the intermediate body 42 protrudes to the right relative to the two side pieces 43, so that the test device provided in this embodiment can be used to observe the detonation of the side airbag under the side column working condition.

[0106] Please refer back to Figure 5 and Figure 6, exemplarily, the connection unit 10 is arranged on the left surface of the column 6 (that is, in the left-right direction, the column 6 and the connection unit 10 fixed on the column 6 are arranged in sequence); the connection unit 10 includes a first plate 101, a second plate 102 and a matching column 103, wherein the first plate 101 and the second plate 102 are both L-shaped bodies, the first plate 101 and the second plate 102 are fixed on the left surface of the column 6, and are spaced apart from each other in the up-down direction; the axial direction of the matching column 103 is the up-down direction, and a portion of the matching column 103 extends into the first plate 1 01 and the second plate 102, the matching column 103 is rotatably connected to the first plate 101 and the second plate 102, so that it can rotate along its own axis relative to the first plate 101 and the second plate 102; corresponding to the matching column 103, the follower 7 is a round rod, and the follower 7 is slidably inserted into the matching column 103 along a direction parallel to the radial direction of the matching column 103, one end of the follower 7 is fixedly connected to the side piece 43, and the other end is located on the side of the matching column 103 away from the side piece 43 based on the design of the follower 7 passing through the matching column 103.

[0107] It can be understood that when the driving device 1 applies a thrust from left to right to the intermediate body 42 of the first base 4, based on the existence of the hinge body 9 and the connection relationship between the follower 7 and the side member 43, as shown in FIG. Figure 7 As shown, the middle body 42 will protrude to the right relative to the front side body 431 and the rear side body 432, and the front side body 431 and the rear side body 432 will adaptively rotate; at this time, the follower 7 will adaptively move with the side piece 43 fixedly connected to itself, and by virtue of the matching relationship between itself and the matching column 103, it will play a role in restraining and supporting the side piece 43; at the same time, the follower 7 will slide relative to the matching column 103 corresponding to itself; the matching column 103 will rotate with its own axial direction as the rotation center.

[0108] Please refer back to Figure 5 and Figure 6 , exemplarily, the test device also includes a second base 8, and the second base 8 basically adopts the design of the first embodiment in terms of overall appearance. In addition, based on the aforementioned postures that the intermediate body 42 and the side pieces 43 will present after the intermediate body 42 is subjected to force, when the first base 4 is in the initial flat rectangular shape, a first junction seam A is formed at the contact between the front side body 431 and the intermediate body 42, and a second junction seam B is formed at the contact between the rear side body 432 and the intermediate body 42. Exemplarily, the second base 8 includes a plurality of separately arranged blocks, and a third junction seam C is formed at the contact between at least two of the plurality of blocks, and a second junction seam D is formed at the contact between at least two of the blocks; the third junction seam C is configured to be aligned with the first junction seam A when the first base 4 is in the initial flat rectangular shape, and the fourth junction seam D is configured to be aligned with the second junction seam B when the first base 4 is in the initial flat rectangular shape. In this way, when the first base 4 becomes as follows Figure 7 When the second base 8 is in the posture shown in FIG. 1 , the second base 8 can also adaptively present the same posture change. In a possible embodiment, the physical diagram of the second base 8 is as shown in FIG. Figure 8 shown.

[0109] It should be noted that, according to the specific test requirements of those skilled in the art, in a possible implementation, the third junction seam C and the fourth junction seam D are not necessarily provided. For example, when the second base 8 is designed to be thin enough, the third junction seam C and the fourth junction seam D are not necessarily provided.

[0110] Please continue reading Fig. 9 In a possible implementation, the relationship between the matching column 103 and the first plate 101 and the second plate 102 can be: the connection unit 10 also includes a shaft 104 extending in an up-down manner, the matching column 103 is between the first plate 101 and the second plate 102, and is respectively loosely matched with the first plate 101 and the second plate 102, the shaft 104 penetrates the first plate 101, the matching column 103 and the second plate 102 in the up-down direction, and is loosely matched with the matching column 103. In this way, the matching column 103 can also rotate with its own axial direction as the rotation center line. In addition, in a possible implementation, such as Fig.10 As shown, the connecting unit 10 may also include a first plate 101 but not a second plate 102 , the matching column 103 may be a cylinder disposed on the first plate 101 , and the follower 7 may be rotatably connected to the cylinder via a sleeve body 11 .

[0111] It can be seen from the above that, under the premise of ensuring that the follower 7 can achieve motion constraint on the side member 43, the shape of the connecting unit 10 is a flexibly settable item for those skilled in the art.

[0112] Please continue reading Fig.11 In a possible implementation, if the first base 4 is required to change between the intermediate body 42 and the side piece 43 after the driving device 1 pushes the intermediate body 42 for a certain period of time, for example, after the first base 4 is subjected to a certain reaction force, Figure 7 The test device further comprises a first latch seat 12 and a first latch body 13. The first latch seat 12 is fixedly provided on each of the two side pieces 43 and the middle body 42. The first latch body 13 can be withdrawn and inserted into the first latch seats 12 located on the two side pieces 43 and the middle body 42. The first latch body 13 and the first latch seat 12 are configured to have a low strength and are configured to adaptively deform after the driving device 1 pushes the middle body 42 for a certain period of time, so that after the first latch body 13 is deformed, the middle body 42 and the side pieces 43 are transformed into the posture shown in FIG. Figure 7 The posture shown.

[0113] Please refer back to Figure 5 and Figure 6 In a possible implementation manner, the steps of using the test device of this embodiment to simulate vehicle intrusion and detonation of the lower airbag may include:

[0114] S1: Select an acceleration collection point, subtract the acceleration curve (or acceleration parameter) generated by the acceleration collection point in the vehicle test or simulation from the acceleration curve generated by the lower end of the B-pillar on the non-collision side (or the bottom of the far B-pillar) in the vehicle test or simulation, and obtain a difference curve; use the difference curve as the input curve of the driving device 1. For example, the acceleration collection point can be set at a position on the door that intrudes into the chest of the dummy after being hit.

[0115] S2: Confirm the value of X3, for example, 30ms. Confirm which position on the test device of this embodiment (remember this position as position β) is equivalent to the position of the acceleration collection point in step S1 (for example, "the position on the door that will intrude into the dummy's chest after being hit" where the acceleration collection point is set in step S1).

[0116] S3: Perform mathematical processing on the acceleration curve in step S1 (e.g., integration processing, subtraction processing, and the method of mathematical processing on such acceleration parameters is common knowledge of those skilled in the art) to obtain a displacement-time diagram, and find the displacement value corresponding to the acceleration collection point in step S1 at the time X3 (e.g., 30ms) confirmed in S2, recorded as d' (e.g., 100mm), calculate d' multiplied by cos15°, and obtain the displacement value of the door position corresponding to the acceleration collection point intruding into the dummy's chest at X3.

[0117] It should be noted that, when the vehicle is subjected to a side-pole collision, the vehicle body and the xz plane form an angle of 75° (this is common knowledge in the art and will not be elaborated on), so the aforementioned d' is not the displacement value of the door position corresponding to the acceleration collection point invading the dummy's chest; after obtaining d', the value of d' multiplied by cos15° is calculated to obtain the displacement value of the door position corresponding to the acceleration collection point invading the dummy's chest (for example, 100*cos15°=96mm).

[0118] S4: According to the value obtained by multiplying d' by cos15° in step S3, the position of the limiter 3 on the base 5 is adjusted to ensure that at 30ms, the value of the position β intrusion dummy confirmed in step S2 on the test device is also approximately the result of multiplying d' by cos15°.

[0119] S5: The driving device 1 is operated to push the first base 4 and start timing, and at the same time, a detonation signal for the side airbag is given.

[0120] S6: Observe the deployment status of the side airbag and the effect of raising the arm.

[0121] Of course, in a possible implementation, one method to confirm the position of the limiter 3 is for a technician in this field to set the position of the limiter 3 on the base 5 based on experience, in combination with data before the test (such as vehicle test data and / or simulation data and / or static detonation test data).

[0122] Embodiment 3

[0123] This embodiment also provides a side airbag detonation test device. The test device provided in this embodiment has a first purpose and a second purpose. When it is used for the first purpose, the test device is used to observe the detonation of the airbag under the side collision condition. When the test device of this embodiment is used for the second purpose, the test device is used to observe the detonation of the airbag under the side column condition. Fig.12 As shown, the test device of this embodiment has basically the same structure as the test device of the second embodiment.

[0124] One of the differences between this embodiment and the first embodiment is that in this embodiment, there is a greater distance between the first base 4 and the columns 6 located at the front and rear sides thereof, and the follower 7 is detachably fixedly connected to the first base 4 by means of threaded connection or clamping.

[0125] The second difference between this embodiment and the first embodiment is that the test device of this embodiment includes two types of follower members 7. One type of follower member 7 is as follows: Fig.12 As shown, it is a straight cylinder, and a follower 7 in one form is as shown in FIG. Fig.14 As shown, it is an L-shaped body; no matter what form the follower 7 is, it can be slidably matched with the matching column 103, and one end of it is configured to be detachably connected to the first base 4 by threaded connection or insertion and then snap-fitting. In this embodiment, when the test device is used for the second purpose (used to observe the detonation of the airbag under the side column working condition), the follower 7 of the straight cylindrical body is used, and the follower 7 of the L-shaped body is not used; when the test device is used for the first purpose (used to observe the detonation of the airbag under the side collision working condition), the follower 7 of the L-shaped body is used, and the follower 7 of the cylindrical body is not used.

[0126] The third difference between the present embodiment and the first embodiment is that the present embodiment is provided with a second latch body 14 and a second latch seat 15 in the middle of the first base 4. The second latch body 14 and the second latch seat 15 are similar in structure to the first latch body 13 and the first latch seat 12 of the first embodiment respectively. Unlike the first embodiment, the second latch body 14 and the second latch seat 15 located in the middle of the first base 4 of the present embodiment have considerable strength and are configured so as not to deform during the test process. In the present embodiment, the second latch body 14 and the second latch seat 15 (located on the two side pieces 43 and the middle body 42) are assembled together when the test device is used for the first purpose, and are not used when the test device is used for the second purpose. In other words, when the test device is used for the second purpose, the second latch body 14 in the middle of the first base 4 withdraws from all the second latch seats 15 and is not used. When the test device is used for the first purpose, the assembly of the second latch body 14 and the second latch seat 15 can ensure that the first base 4 maintains the shape of a flat rectangular parallelepiped during the test process.

[0127] Please refer to Fig.12 and Fig.13 When the test device of this embodiment has been used for the second purpose and is to be used for the first purpose again, all the connecting units 10 are removed and respectively installed on the mutually facing surfaces of the two columns 6 (i.e., the rear surface of the front column 6 and the front surface of the rear column 6), and then the L-shaped follower 7 is connected to the first base 4 and slidably inserted into the matching column 103, and then the second latch body 14 is matched with all the second latch seats 15 in the middle of the first base 4. It can be understood that Fig.14 and Fig.15 As shown, the test device can now be used for the first purpose, and in the following entire test process, due to the restriction of the second latch body 14, the side piece 43 can no longer rotate relative to the middle body 42.

[0128] It is understandable that the number of connection units 10 can be flexibly designed by those skilled in the art, provided that at least two connection units 10 are located between the two columns 6, that is, at least one connection unit 10 is provided on the rear surface of the front column 6 and on the front surface of the rear column 6.

[0129] Please continue reading Fig.16 In a possible implementation, when the first base 4 is provided with a first latch body 13 and a first latch seat 12 as in the second embodiment, relative to the second embodiment, the first latch body 13 and the first latch seat 12 are located on the side of the second latch body 14 and the second latch seat 15. It can be understood that Fig.16 The figure is only one of many arrangements of the first latch body 13, the first latch seat 12, the second latch body 14 and the second latch seat 15 on the first base 4. Those skilled in the art are able to flexibly design the arrangement of the first latch body 13, the first latch seat 12, the second latch body 14 and the second latch seat 15 on the first base 4 according to needs.

[0130] It should be noted that the reason why this embodiment can be used to observe the detonation of the airbag under side collision conditions by changing the connecting unit 10 so that the structure is basically equal to that of the test device in the second embodiment is that: as described in the first embodiment, the first base 4 of the utility model does not need to slide a long distance, and the test conducted by the utility model only requires a small amount of intrusion so that the test personnel can observe the deployment state of the side airbag and the effect of raising the arm.

[0131] More specifically, conventional prior art is that technicians would use Fig.17 The device shown in the figure is used for a sled test to verify the detonation of the airbag under the side collision condition; the device is configured to include a first plate G and a second plate H, the first plate G and the second plate H form a first base 4 similar to the present embodiment, and are configured to be able to explode after colliding with an equivalent structure of the impacted vehicle, such as Fig.17 As shown, the second plate H is in front and the first plate G is in the back, which is a staggered form to simulate the deformation of the person who hits the vehicle after hitting the vehicle. It can be understood that this staggered form only appears at a later time of the impact (for example, 50-60ms after the start of the impact), that is, a time greater than X3, and this embodiment does not need to be carried out until such a late time, and there is no need to consider that the second base 8 with the door trim and the B-pillar trim installed, and the first base 4 connected to the second base 8, both of which have a structure that can be staggered between the upper and lower parts; it is also for this reason that for this embodiment, the use of the test device of this embodiment can be switched between the first use and the second use by reassembling the test device of this embodiment, so as to save the test site and test costs.

[0132] Embodiment 4

[0133] like Fig.18 and Fig.19 As shown, this embodiment also provides a side airbag detonation test device. The test device provided in this embodiment is used to observe the detonation of the airbag under the side column working condition. Fig. 20 As shown in FIG. 1 , the operating principles and connection relationships of the various components of the test device in this embodiment are all designed as described in Example 2. Fig.18 and Fig.19 The vehicle seat 16, the B-pillar trim 17 and the door trim 18 are marked. The approximate orthographic projection of the B-pillar trim 17 and the door trim 18 on the first base 4 is approximately Fig.21 As shown, the dashed area E represents the approximate orthographic projection of the door trim panel 18 on the first base 4 , and the dashed area F represents the approximate orthographic projection of the B-pillar trim panel 17 on the first base 4 .

[0134] Furthermore, the driving device 1 of this embodiment includes a driving body 1a and a driving rod 1b arranged and connected in sequence from left to right, wherein the driving body 1a is a servo driving device, one end of the driving rod 1b is connected to the driving body 1a, and the other end is connected to the driving rod 1b. Furthermore, in order to ensure the stability of the driving rod 1b, this embodiment also provides a support body 19 between the driving body 1a and the column 6, and the support body 19 is configured to have a shape that supports the driving rod 1b but does not affect the movement of the driving rod 1b.

[0135] In summary, the test device of the present invention can simulate a similar real vehicle situation in which the vehicle-related structures are located next to the vehicle seat, so that the first base 4 can carry the B-pillar trim 17 and the door trim 18 to collide with the vehicle seat 16 with the dummy, thereby simulating the situation of the vehicle being hit on the side during the whole vehicle test. Based on the test device provided by the present invention, those skilled in the art can use the test device to evaluate the side airbag before the whole vehicle test, and / or after the whole vehicle test and before the trolley test, and perform the trolley test after the optimization iteration of the side airbag is completed according to the evaluation results of the side airbag, thereby indirectly reducing the number of trolley tests, indirectly saving manpower and material resources, and reducing the development cost of the vehicle.

[0136] Furthermore, since the impact time required for the test device to occur during the test is shorter than that of the trolley test regardless of whether it is used for the first purpose or the second purpose, the probability of damage to the components of the test device during the test is relatively small, and the number of times it can be reused is relatively high; it is understandable that this can further reduce the development cost of the vehicle.

[0137] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
