The metal instrument panel has the following differences from a real instrument panel: the metal instrument panel is provided with a through hole, the safety airbag is exploded out of the through hole, the real instrument panel is provided with a safety airbag door, and the safety airbag is exploded and then breaks through the safety airbag door by means of self expansion force, so that the safety airbag is unfolded. Based on this difference, first, since the airbag of the metal instrument panel does not need to open the airbag door, the airbag of the metal instrument panel is deployed and contacts the virtual human model earlier than the airbag in the real instrument panel, for example, 2ms earlier than the real instrument panel; secondly, when the airbag in the real instrument panel is unfolded and breaks the airbag door, the tearing of the airbag door can absorb part of energy, so that the airbag in the metal instrument panel has larger energy than the airbag in the real instrument panel; third, the airbag door on a real instrument panel will have an upward supporting effect on the deployed airbag after opening, and thus the airbag in the metal instrument panel will be lower in the Z direction than the airbag in a real instrument panel. Therefore, when a pulley experiment is performed, the metal instrument panel in the prior art cannot completely simulate the effect of a real instrument panel on the airbag, so that not only can the error and inaccuracy of experimental data be caused, but also certain influence can be generated on the design parameters and the like of the airbag.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
An airbag is provided inside the real instrument panel 1, and an airbag door 2 is provided on the real instrument panel. The airbag door 2 is connected to the real instrument panel 1 by a weakening line 3. Fig. 1 shows a weakening line 3 of an airbag door 2 in an H-shape, and upon receiving an airbag firing signal, the airbag is inflated to expand, and the expanded and deployed airbag breaks the weakening line 3 by its own deployment force to open the airbag door 2, thereby breaking out a real instrument panel 1 to be deployed, thereby achieving a passenger protection effect. As described in the above background, in the process of the airbag breaking the airbag door 2, firstly, energy is required to break the weakened line 3, and therefore the airbag door 2 absorbs a portion of the energy of the airbag; secondly, it takes a certain time to break the weakening line 3; third, the opened airbag door may have an upward supporting effect on the deployed airbag. And includes, during an airbag door opening process: a process in which the detonated airbag tears the line of weakness around the airbag door to open the airbag door, wherein the torn line of weakness cannot be re-bonded back again; the process of opening the airbag door to re-close by self elastic deformation after the airbag is removed. The present invention has been made based on this.
The metal instrument panel according to the embodiment of the invention is used for replacing a real instrument panel during the pulley test of the air bag, and some parameters of the air bag are obtained through experiments by simulating the curved surface appearance of the metal instrument panel.
The interior of the metal instrument panel 10 according to the embodiment of the present invention is provided with an airbag for a pulley test. The metal instrument panel 10 is provided with a door 20 corresponding to an airbag, which is rapidly expanded after being detonated and is unfolded by opening the door by its own expansion force to protect a passenger. As shown in fig. 2, the door cover 20 may be provided as a double door corresponding to the weakening line of the H-type in fig. 1, i.e., the door cover 20 is connected to the metal instrument panel 10 at upper and lower opposite sides by hinges, the door cover 20 being opened from the middle and opened toward the metal instrument panel 10 toward the hinges opposite to both sides. The opening manner and shape of the door cover 20 are not limited thereto, and may be adjusted and changed accordingly according to the shape and opening manner of the airbag door on the real instrument panel to be simulated, to obtain more accurate parameters of the airbag during the pulley test. For example, as shown in fig. 3, the door cover 20 may be provided as a single-door corresponding to the weakening line of the U-shape, i.e., one side of the door cover 20 is connected to the metal instrument panel 10 by a hinge, and the door cover 20 is opened from the opposite other side and opened to the metal instrument panel with respect to the hinge.
The hinge may include at least one energy-absorbing unit 100 and at least one resilient unit 200. That is, the door cover 20 may be coupled to the metal instrument panel 10 by at least one energy absorption unit 100 and at least one elastic unit 200. The energy absorbing unit 100 can absorb a part of energy during the opening of the door cover 20, corresponding to the energy absorbing process when the airbag door is opened on the real instrument panel. The specific structure of the energy-absorbing unit 100 will be described in detail below. After the door cover 20 is opened, the elastic unit 200 can re-close the door cover according to its own elastic force, which corresponds to a process in which the airbag door on the real instrument panel is re-closed by its own elastic deformation. The energy absorbing unit 100 and the elastic unit 200 are disposed along a connection line of the door cover 20 and the metal instrument panel 10 to form a hinge. The energy-absorbing unit 100 and the resilient unit 200 may be in contact with each other or spaced apart from each other. The energy-absorbing units 100 and the elastic units 200 may be arranged alternately or in any order as desired, for example, in the order of elastic units-energy-absorbing units-elastic units-energy-absorbing units-elastic units as shown in FIG. 1. Since different numbers and arrangement orders of the elastic units and the energy absorbing units can produce different states and effects during and after the airbag is opened, the numbers and arrangement orders of the elastic units 200 and the energy absorbing units 100 can be appropriately adjusted according to the actual airbag door to be simulated. The elastic unit 200 and the energy-absorbing unit 100 can be manufactured into standard parts, and different numbers of the energy-absorbing units 100 and the elastic units 200 can be arranged and combined according to different sequences to meet the simulation requirements of airbags of different vehicles with different models and different parameters. In addition, in a pulley laboratory, the energy absorption unit 100 absorbs part of the energy by breaking itself when the airbag is deployed, so that the energy absorption unit 100, which is made as a standard piece, can be easily replaced after each pulley experiment.
FIG. 4A shows a schematic view of an energy-absorbing unit 100 according to the invention; FIG. 4B shows a perspective view of FIG. 4A; FIG. 5 shows a schematic view of a first beam 110 of the energy-absorbing unit 100 according to the invention.
Referring to FIGS. 4A-5, the energy-absorbing unit 100 includes a first beam 110 and first connectors 120 of 110-2 disposed at ends of both ends of the first beam. The first links 120 are non-rotatably fixed to the ends 110-2 of the first rods, and one of the first links 120 is coupled to the door cover 20 located at one side of the elastic unit 110 and the other of the first links 120 is coupled to the metal dash panel 10 located at the other side of the elastic unit 100, i.e., the two first links 120 fixed to the first rods 110 extend in opposite directions to be coupled to the door cover 20 and the metal dash panel 10, respectively. When the door cover 20 is opened, the two first links 120 respectively connected to the door cover 20 and the metal instrument panel 10 are relatively rotated, and since the two first links 120 are non-rotatably fixed to the end portions 110-2 of the both ends of the first lever 110, the end portions 110-2 of the both ends of the first lever 110 are relatively rotated, so that the first lever 110 generates a torque, and when the door cover 20 is opened to a certain extent, the torque generated on the first lever 110 is greater than a critical torque of the first lever 110, the first lever 110 is broken, and the process absorbs a part of energy, thereby corresponding to a process of breaking the weakening line to absorb a part of energy when the airbag door on the real instrument panel is opened.
The first rod 110 further includes a middle portion 110-1 between the end portions 110-2 at both ends, and the middle portion 110-1 may be cylindrical, i.e., have a circular cross-section. The two end portions 110-2 may be polygonal prisms, i.e. have a polygonal outer contour 30, i.e. a polygonal cross-section. For example, the end 110-2 may be hexagonal, i.e., hexagonal in cross-section, i.e., having a hexagonal outer profile. The present invention is not so limited and can be modified and adapted as needed or desired, for example, the end portion 110-2 can be a quadrangular prism, an octagonal prism, etc., and the middle portion 110-1 can also be a polygonal prism, for example, identical to the end portion 110-2, for ease of manufacture. The end 110-2 of the polygonal prism may be mated with the first link 120 such that the first link 120 is not rotatable with respect to the first beam 110, thereby achieving an energy absorbing effect.
The first connecting member 120 includes a ring-shaped portion 120-1 fitted over the end portion 110-2 of the first rod 110 and a plate-shaped portion 120-2 connecting the door cover 20 and the metal instrument panel 10. The annular portion 120-1 is annular and is fitted over the end 110-2 of the first rod 110, as mentioned above, the annular portion 120-1 having an internal profile matching that of the end 110-2, for example a polygonal internal profile 50, more particularly a hexagonal internal profile, that is to say a polygonal, in particular hexagonal, cross-section. The ring portion 120-1 of the first link 120 is fixed to the end portion 110-2 of the first rod 110 by the matching polygonal edges without relative rotation. The present invention is not limited thereto, and the end of the first rod 110 and the first link 120 may be fixed in other manners as long as they do not move relatively. The plate-shaped portion 120-2 extends from the ring-shaped portion 120-1 toward the door cover 20 or the metal fascia 10, the door cover 20 and the metal fascia 10 are respectively located at both sides of the first rod 110, and thus the first links 120 located at both ends of the first rod 110 are respectively extended toward both sides of the first rod 110 to be respectively connected to the door cover 20 and the metal fascia 10. The ring-shaped portion 120-1 and the plate-shaped portion 120-2 are integrally formed. The plate-shaped portion 120-2 is provided with a first coupling hole 70, and the first coupling hole 70 may have a size corresponding to a size of a fastening standard in the art to fix the first coupling member 120 to the door cover 20 or the metal instrument panel 10 using the standard. The door cover 20 and the metal instrument panel 20 may be coupled to the first coupling member 120 using a tapping screw. The door cover 20 is pushed to be opened by its own expansion after the airbag is detonated, at which the door cover 20 rotates about a hinge with respect to the metal instrument panel 10, the first link 120 fixedly connected to the door cover 20 relatively rotates with the door cover 20 with respect to the first link 120 fixed to the metal instrument panel 10 at the other end of the first lever 110, so that both ends of the first lever 110 relatively rotate to generate a torque to the first lever 110, the first lever 110 is torsionally deformed by the torque, and when the door cover 20 is opened to a certain extent, the torque generated to the first lever 110 reaches a limit torque of the first lever 110, so that the first lever 110 is broken when the first lever 110 reaches the limit torsional deformation, thereby absorbing a part of energy.
Fig. 6A shows a schematic view of an elastic unit 10 according to the invention; FIG. 6B shows a perspective view of FIG. 6A; fig. 7 shows a schematic view of the second lever 210.
Referring to fig. 6A to 7, the elastic unit 200 includes a second lever 210, a second link 220 rotatably disposed at end portions 210-2 of both ends of the second lever 210, and a spring 230 fitted over the second lever 210 and having both ends connected to the second link 220 disposed at the end portions 210-2 of the second lever 210, respectively. The second links 220 are rotatably provided at both end portions 210-2 of the second lever 210, and one of the second links 220 is connected to the door cover 20 at one side of the second lever 210 and the other of the second links 220 is connected to the metal instrument panel 10 at the other side of the second lever 210, i.e., the two second links 220 provided at the end portions 210-2 of the second lever 210 are respectively extended in opposite directions to be connected to the door cover 20 and the metal instrument panel 10, respectively. The spring 230 is sleeved on the second rod 210, and two ends of the spring 230 are respectively and fixedly connected to the second connecting members 220 at two ends of the second rod 210. When the door 20 is opened, the two second connecting members 220 respectively connected to the door 20 and the metal instrument panel 10 are relatively rotated, and since the second connecting members 220 can be rotated with respect to the second rod 210, when the door 20 is opened, the second rod 210 is not rotated, and the second connecting members 220 are relatively rotated with respect to each other, that is, the two connecting members 220 at the two ends of the second rod 210 are rotated in opposite directions, so that the two ends of the spring 230 sleeved on the second rod 210 are relatively rotated against the self-elastic force of the spring 230 to torsionally deform the spring. When the force for opening the door 20 disappears, the spring 230 returns to its original shape under its own elastic force, so that the door 20 is re-closed, which corresponds to a process in which the airbag door on the real soft film instrument panel is opened and the airbag is removed, and then returns to its original shape and re-closed under its own elastic deformation. The second rod 210 further includes a middle portion 210-1 between the two end portions 210-2, and the middle portion 210-1 and the two end portions 210-2 may be cylindrical, i.e., the end portions 210-1 may have a circular outer profile 40, so as to facilitate the rotation of the second connector 220 with respect to the second rod 210, and to facilitate the manufacturing and molding, thereby reducing the cost.
The second link 220 includes a ring portion 220-1 fitted over the end 210-2 of the second rod 210 and a plate portion 220-2 connecting the door cover 20 and the metal instrument panel 10. The ring shaped portion 220-1 has a circular inner contour 60 matching the circular outer contour 40 of the end portion 210-2 of the second rod 210 to enable rotation of the second connector 220 relative to the second rod 210. The present invention is not limited thereto and may be adjusted and modified according to design and need as long as the relative rotation of the second link 220 with respect to the second lever 210 can be achieved. The plate-shaped portions 220-2 extend from the ring-shaped portions 220-1 toward the door cover 20 and the metal instrument panel 10, respectively, the door cover 20 and the metal instrument panel 10 being located at both sides of the second rod 210, respectively, so that the second connectors 220 located at both ends of the second rod 210 extend oppositely toward both sides of the second rod 210 to be connected to the door cover 20 and the metal instrument panel 10, respectively. The ring portion 220-1 and the plate portion 220-2 are integrally formed. The plate-shaped portion 220-2 is provided with second coupling holes 80, and the second coupling holes 80 may have a size corresponding to a size of a fastening standard in the art to fix the second coupling member 220 to the door cover 20 and the metal instrument panel 10 using the standard. In particular, the second connection hole 80 and the first connection hole 70 may be identical to each other to facilitate the interchange between the resilient unit and the energy-absorbing unit. Different simulation requirements can be conveniently met. The door cover 20 and the metal instrument panel 20 may be coupled to the second coupling member 220 using a tapping screw.
The spring 230 is sleeved on the second rod 210, and both ends of the spring 230 extend along the length direction of the second rod 210 to be inserted into the spring connecting holes 90 on the second connecting member 220 in the same extending direction. The present invention is not limited thereto and may be changed and adjusted according to design and need.
The door 20 is pushed to open by its expansion after the airbag is detonated, at which time the door 20 is hinged around the hinge, i.e., the first lever 110 and the second lever 210 are rotated outward with respect to the metal instrument panel 10, the second link 220 fixedly coupled with the door cover is rotated with respect to the second lever 210 as the door cover 20 is opened, since the other link 220 connected to the metal instrument panel 10 is kept stationary, the two second links 220 respectively located at both ends of the second lever 210 are rotated relative to each other, and, accordingly, so that both ends of the spring 230 are also rotated relative to each other, so that the spring 230 is torsionally deformed against the elastic force of the spring 230, the torsional deformation can be restored by the elastic force of the spring 230 itself after the load disappears, that is, after the airbag is removed, the spring 230 is restored to the torsional deformation by its own elastic force, thereby allowing the door cover 20 to be closed again. Thus, after the airbag is detonated, it collides to open the door, in the process, the first rod 110 of the energy absorbing unit 100 is broken and absorbs a portion of the energy, the spring 230 in the elastic unit 200 is torsionally deformed, and when the airbag is removed, the spring 230 of the elastic unit 200 is restored to be deformed such that the door is re-closed. Therefore, the metal instrument panel can more accurately simulate the detonation process of the safety air bag in the real soft membrane instrument panel, so that more accurate and reliable parameters are obtained, and the development and the design of the safety air bag are more facilitated. The resilient units and the energy-absorbing units can be mass-produced in the same size at the time of production, so that the replacement and the order of arrangement of the locations of the resilient units and the energy-absorbing units are facilitated.
In summary, the present invention provides a metal instrument panel, an airbag is disposed inside the metal instrument panel for a pulley test, a door corresponding to the airbag is disposed on the metal instrument panel, and the door is connected to the metal instrument panel through at least one energy absorption unit and at least one elastic unit. Therefore, the metal instrument board is provided with the door cover through which the safety air bag passes so as to simulate the safety air bag door on the real instrument board, the safety air bag is supported upwards after the door cover is opened, and the door cover is connected to the metal instrument board through at least one elastic unit and at least one energy absorption unit, wherein the energy absorption unit can simulate the energy absorption process of the safety air bag door on the real instrument board in the tearing process; the elastic unit can simulate the process that an airbag door on a real instrument panel can be closed again after being opened and an airbag is removed. According to the metal instrument panel, the door cover is connected with the door cover through the door cover and the elastic unit and the energy absorption unit, so that the process that the safety airbag in the real instrument panel breaks through the safety airbag door can be simulated to the greatest extent, and more real and more reliable experimental data can be obtained as far as possible on the premise of reducing the cost, so that the safety airbag can be developed more favorably.
