Description

Technical Field

[0001] The utility model relates to the field of vehicle safety testing, in particular to a co-pilot airbag test device. Background Art

[0002] In the product research and development of vehicle airbags, it is necessary to test the designed airbag under a specific vehicle model. For example, after the ignition device of the airbag is ignited, it is necessary to test whether the unfolding process of the airbag meets the design requirements.

[0003] Generally, the ignition tooling has an instrument panel imitation body and a windshield imitation body. During the experiment, the airbag to be tested is fixed on the instrument panel imitation body. In the environment of the instrument panel imitation body and the windshield imitation body, the airbag unfolds and impacts the windshield imitation body to evaluate the characteristics of the airbag to be tested. The force characteristics of the windshield imitation body during the airbag unfolding process are one of the evaluation contents. To accurately collect the force on the windshield, in terms of structural layout, after the airbag to be tested is fully unfolded, it generally presses on the center position of the windshield imitation body. Therefore, a single-axis force sensor is set at the center position of the windshield imitation body.

[0004] However, during the process from the start of airbag unfolding to full unfolding, the airbag has various forms. During the dynamic unfolding process, the impact position of the airbag on the windshield imitation body will change dynamically. The single-axis force sensor set in the center will have obvious measurement errors due to the slight skew of the windshield. Content of the Utility Model

The first feature being "below", "below the bottom", and "under the bottom" of the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0040] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0041] Such as Figure 1As shown, this embodiment provides a co-pilot airbag test device. An airbag 240 to be tested is installed on the co-pilot airbag test device, and a deployment test of the airbag 240 to be tested is carried out. The co-pilot airbag test device includes a test bench 100, an instrument panel imitation part 200, a windshield imitation part 300 and a windshield force detection part. The instrument panel imitation part 200 refers to a structural part designed according to the shape of the actual instrument panel, which saves test costs. The windshield imitation part 300 refers to a structural part designed according to the shape of the actual windshield glass, which saves test costs.

[0042] In this embodiment, the front-rear direction refers to the front-rear direction of the vehicle. The front refers to the forward direction of the vehicle, and the rear refers to the backward direction of the vehicle. The left-right direction refers to the left-right direction of the vehicle, that is, the width direction of the vehicle.

[0043] As Figures 1 - 3 shown, the instrument panel imitation part 200 is arranged on the test bench 100. The windshield imitation part 300 is arranged on the test bench 100 and is located on one side of the instrument panel imitation part 200. In this embodiment, the windshield imitation part 300 is located at the upper front side of the instrument panel imitation part 200. The windshield force detection part includes at least three force sensors 500. The force sensors 500 are used to detect the force on the windshield imitation part 300. At least three of the force sensors 500 are non-collinear, and the force sensors 500 are arranged at intervals on the side of the windshield imitation part 300 facing away from the instrument panel imitation part 200. The instrument panel imitation part 200 is configured to install the airbag 240 to be tested. The airbag 240 to be tested is located below the instrument panel imitation part 200.

[0044] At least three of the force sensors 500 are non-collinear. In other words, the force sensors 500 are arranged in a two-dimensional plane or a three-dimensional space distribution manner. Moreover, the force sensors 500 are arranged on the side of the windshield imitation part 300 facing away from the instrument panel imitation part 200 to collect the force exerted by the airbag on the other side of the windshield imitation part 300. Each force sensor 500 collects the force on the windshield imitation part 300 at different positions. The force sensors 500 cooperate with each other to jointly reflect the comprehensive force of the windshield imitation part 300. No matter in which direction the windshield imitation part 300 is skewed, the force of the windshield imitation part 300 is determined by the combination of all the force sensors 500. Compared with a single and centered force measurement method, the acquisition error is significantly reduced.

[0045] As Figure 3As shown, optionally, the windshield force detection member includes four force sensors 500, which are distributed in a matrix to form a force reference plane. Moreover, the four force sensors 500 take into account the measurement in all 360° directions around the plane. Any deviation of the windshield profiling member 300 from the force reference plane will simultaneously cause changes in the forces on the four force sensors 500, reducing measurement errors while controlling the number of measurement sensors. In this embodiment, the windshield profiling member 300 can be either a curved surface or a flat surface, both of which are applicable to the force reference plane. In other embodiments, the force sensors 500 can also be arranged in a three-dimensional space in a three-dimensional manner.

[0046] As Figure 3 shown, optionally, the four force sensors 500 are all arranged at the edge of the windshield profiling member 300. The force reference plane formed by the four force sensors 500 covers the windshield profiling member 300 more widely, which is beneficial to reducing the measurement error of the comprehensive force. In other embodiments, a force sensor 500 can also be provided at the center of the windshield profiling member 300.

[0047] Preferably, the force sensor 500 includes a triaxial force sensor. The triaxial force sensor can collect the forces in three directions at the position it collects, which is beneficial to improving the force collection accuracy of the windshield profiling member 300. When the measurement accuracy requirement is relatively low, a uniaxial force sensor 500 can also be used.

[0048] As Figures 1 - 3 shown, optionally, the test bench 100 includes a windshield mounting frame 140. The windshield profiling member 300 is arranged inside the windshield mounting frame 140, and each force sensor 500 is arranged on the windshield mounting frame 140 and is in contact with the windshield profiling member 300. The windshield mounting frame 140 mounts and supports the windshield profiling member 300 inside it on the one hand, and mounts each force sensor 500 on the other hand. With the windshield mounting frame 140, it is convenient to reasonably arrange each force sensor 500 on one side of the windshield profiling member 300. Specifically, the windshield mounting frame 140 is a rectangular frame, the windshield profiling member 300 is generally rectangular, and the four force sensors 500 are all arranged on the rectangular frame and are distributed at the four corners of the windshield profiling member 300. Exemplarily, the windshield profiling member 300 is an acrylic board.

[0049] Optionally, a plurality of area measurement grids are evenly distributed on the windshield profiling member 300. According to the number of area measurement grids occupied after the airbag is deployed, the bearing area of the windshield profiling member 300 can be obtained. Then, in combination with the impact force collected by the windshield force detection member, the pressure-time curve borne by the windshield profiling member 300 per unit area can be calculated. In one embodiment, the area measurement grids are formed by scribing on the windshield profiling member 300, which is simple to implement and does not affect the structure of the windshield profiling member 300. In another embodiment, the area measurement grids are projected onto the side of the windshield profiling member 300 facing the instrument panel profiling member 200 by optical projection, which also does not affect the structure of the windshield profiling member 300.

[0050] Optionally, the co-pilot airbag test device further includes a first fastener. The instrument panel profiling member 200 is rotatably arranged on the test bench 100, and the first fastener can fixedly connect the instrument panel profiling member 200 and the test bench 100. When the first fastener is disconnected, the instrument panel profiling member 200 can be rotated to adjust its inclination to provide various instrument panel environments for the airbag. Then, by using the first fastener to fixedly connect the instrument panel profiling member 200 and the test bench 100, the instrument panel profiling member 200 can be fixed. In this embodiment, the instrument panel profiling member 200 adjusts its inclination in the front-rear direction.

[0051] As Figure 1 and Figure 2 As shown in [figures not provided], optionally, the test bench 100 includes an instrument panel support member 130. The instrument panel profiling member 200 is rotatably arranged on the instrument panel support member 130 through a rotating shaft 220. A plurality of locking holes 131 are provided on the instrument panel support member 130, and the locking holes 131 are circumferentially distributed on the outer periphery of the rotating shaft 220. A positioning hole is provided on the instrument panel profiling member 200, and the positioning hole is connected to any one of the locking holes 131 through the first fastener. By unlocking the first fastener, the instrument panel profiling member 200 can be rotated to adjust its angle. By using the first fastener to lock the positioning hole and the locking hole 131, the instrument panel profiling member 200 can be fixed. The solution of this embodiment is simple and convenient to implement.

[0052] As Figure 1 and Figure 2As shown, optionally, the test bench 100 includes an upper support member 110 and a lower support member 120. The upper support member 110 is higher than the lower support member 120. The windshield profiling member 300 is provided with a first connection portion and a second connection portion. The first connection portion is adjustably connected to the upper support member 110, and the second connection portion is adjustably connected to the lower support member 120. That is to say, the change in the position of the first connection portion on the upper support member 110 and the change in the position of the second connection portion on the lower support member 120 will change the pitch angle or position of the windshield profiling member 300. Through the above settings, the first connection portion and the upper support member 110 always remain connected, and the second connection portion and the lower support member 120 always remain connected. It is always fixed and stable before and after the attitude change, realizing the adjustment of the position and pitch angle of the windshield profiling member 300, and providing a variety of windshield arrangement environments for the airbag. Specifically, the upper support member 110 includes two support arms, and the two support arms are located on both sides of the windshield mounting frame 140 in the left-right direction. The first connection portions connected to the support arms are provided on both side walls of the windshield mounting frame 140. The lower support member 120 includes two support plates, and the two support plates are located on both sides of the windshield mounting frame 140 in the left-right direction. The second connection portions connected to the support plates are provided at the lower ends of both side walls of the windshield mounting frame 140. In other embodiments, the windshield profiling member 300 can also be arranged on a rotating frame located on a lifting platform. The rotating frame adjusts the pitch angle of the windshield profiling member 300, and the lifting platform adjusts the height position of the windshield profiling member 300.

[0053] As Figure 1 and Figure 2 As shown, optionally, the first connection portion includes a first elongated hole 141, and the upper support member 110 is provided with a second elongated hole 111. The first elongated hole 141 and the second elongated hole 111 are connected by a second fastener at the intersection. Unlock the second fastener, and the intersection position of the first elongated hole 141 and the second elongated hole 111 can be adjusted, that is, the position or pitch angle of the windshield profiling member 300 can be adjusted. Lock the first elongated hole 141 and the second elongated hole 111 with the second fastener, and the windshield mounting frame 140 can be fixed to keep the windshield profiling member 300 fixed. The solution of this embodiment has a simple structure and is easy to implement. Specifically, the support arm is horizontal and extends in the front-rear direction, and the second elongated hole 111 is in the same extending direction as the support arm. The windshield mounting frame 140 is a rectangular frame, and the extending direction of the first elongated hole 141 is parallel to the length direction of the rectangular frame.

[0054] As Figure 1 and Figure 2As shown, optionally, the second connecting portion includes a second connecting hole, and a plurality of lower connecting holes 121 are provided on the lower support member 120. The second connecting hole is selectively connected to the lower connecting hole 121 through a third fastening member. Unlock the third fastening member, and the position or pitch angle of the windshield profiling member 300 can be adjusted. Lock the first connecting hole and the second connecting hole with the third fastening member to fix the windshield mounting frame 140 and keep the windshield profiling member 300 fixed. The structure of the solution in this embodiment is simple and easy to implement. The third fastening member can be a bolt-nut assembly.

[0055] As Figure 1 and Figure 2 shown, for safety testing of a vehicle model with a co-pilot large screen, optionally, the co-pilot airbag test device further includes a co-pilot large screen profiling member 600. The co-pilot large screen profiling member 600 is located at the rear side of the instrument panel profiling member 200 and is adjustably arranged on the test bench 100. The co-pilot large screen profiling member 600 refers to a structural member designed in the shape of the co-pilot large screen, which saves testing costs. Adjusting the position of the co-pilot large screen profiling member 600 will also adjust the layout environment of the airbag to be applicable to multiple vehicle models. As Figure 1 and Figure 2 shown, optionally, the co-pilot airbag test device further includes a co-pilot large screen support structure 700. The co-pilot large screen support structure 700 includes a first bracket 710 and a second bracket 720. The first bracket 710 is adjustably arranged on the test bench 100 in terms of height. The second bracket 720 is adjustably arranged on the first bracket 710 in a first direction. The co-pilot large screen profiling member 600 is adjustably arranged on the second bracket 720 in a second direction. The first direction, the second direction, and the height direction are perpendicular to each other in pairs. Through the above settings, the position of the co-pilot large screen profiling member 600 in space is adjusted, and the structure is simple. In another embodiment, the co-pilot large screen support structure 700 includes a vertical slide rail and a horizontal slide rail. The vertical slide rail extends in the height direction.
