Abstract
The utility model relates to an air bag cover board which is arranged on an unfolding port of a safety air bag; the air bag cover board is provided with a weakening line crazed when the air bag is unfolded; the weakening line is positioned on the surface of the air bag cover board in trailing direction with an air bag generator. When the air bag cover board is in the process of fracture and opening at the weakening line, the weakening line is positioned on the surface of the air bag cover board in trailing direction with the air bag generator under the same air bag pressure, and the thickness of the weakening line is larger than that of the weakening line when the weakening line is on the surface of the air bag cover board in trailing direction with the air bag generator, and so the condition is good for the manufacture of die and plastic injection modeling of the air bag cover board.
Description
Technical field
The utility model relates to a kind of air bag cover plate, specifically, relates to a kind of air bag cover plate that is used for the automobile panel occupant-side safety airbag deployment opening.
Background technology
On the occupant-side safety airbag cover plate commonly used line of weakness is arranged all.Air-bag activation is opened moment, and instrument carrier panel occupant-side safety airbag cover plate can rupture under the effect of safety airbag pressure along line of weakness and open.Present vehicle, line of weakness all are distributed in that side towards the air bag producer of air bag cover plate.The thickness at line of weakness place is less than normal, and Shooting Technique is had higher requirement.
The utility model content
The technical problems to be solved in the utility model provides a kind of assurance air bag and opens under same gasbag pressure effect, and the thickness at line of weakness place increases, the simple air bag cover plate of processing technology.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of air bag cover plate, this air bag cover plate is installed on the air-bag deployment mouth, and the air bag cover plate is provided with the line of weakness that ftractures when airbag deployment, and described line of weakness is positioned on the air bag cover plate surface of air bag producer dorsad.
Described line of weakness can be H type or U type, or two Y types that are connected.
The thickness of described line of weakness be described air bag cover plate thickness 1/3 to 1/2.
Adopt the air bag cover plate of said structure, the air bag cover plate is in the process that the fracture of line of weakness place is opened, under same gasbag pressure, when line of weakness is positioned on the air bag cover plate air bag producer dorsad surperficial, therefore the thickness of line of weakness be more conducive to the injection molded of the gentle bag cover plate of manufacturing of mould than bigger when the air bag cover plate is on the surface of air bag producer in line of weakness.
Description of drawings
Fig. 1 is air bag cover plate principle of design figure of the present utility model;
Fig. 2 is the scheme drawing that the line of weakness of air bag cover plate of the present utility model is the embodiment of U type;
Fig. 3 is the scheme drawing that the line of weakness of air bag cover plate of the present utility model is the embodiment of H type;
Fig. 4 is the scheme drawing that the line of weakness of air bag cover plate of the present utility model is the embodiment of two continuous Y types.
The specific embodiment
According to Fig. 1 to Fig. 4, provide preferred embodiment of the present utility model, and described in detail below, enable to understand better function of the present utility model, characteristics.
Fig. 1 is air bag cover plate principle of design figure of the present utility model.As shown in the figure, air bag cover plate 1 is installed on the air-bag deployment mouth place of automobile passenger side, with instrument board framework 2 by welding, riveted joint or bolted connection together, air bag producer 4 is positioned at the air-bag deployment mouth.Air-bag activation is opened moment, and instrument carrier panel occupant-side safety airbag cover plate can provide the space of gasbag expansion, thereby the protection to the occupant side personnel is provided opening by 3 rotations of the line of weakness on the air bag cover plate 1 under the effect of safety airbag pressure.Air bag cover plate 1 is often made by molding synthetic resin, and line of weakness 3 is positioned on the air bag cover plate surface of air bag producer dorsad.Usually line of weakness 3 is to form by the raised line that is arranged on the mold cores face that is used for moulding air bag cover plate, also can pass through laser formation.If the thickness of the line of weakness 3 on the air bag cover plate 1 is smaller, the thickness of the raised line on the airbag cover board forming die is also smaller accordingly, can increase the difficulty of mould-manufacturing like this, want simultaneously in the process of mould molding air bag cover plate, the requirement of technology controlling and process is also higher.And when line of weakness 3 was positioned on the air bag cover plate 1 air bag producer 4 dorsad surperficial, the line of weakness of condition of equivalent thickness was than can opening easilier when the air bag cover plate is on the surface of air bag producer 4 in line of weakness.That is to say, under same gasbag pressure, when line of weakness 3 was positioned on the air bag cover plate 1 air bag producer 4 dorsad surperficial, therefore the thickness of line of weakness 3 be more conducive to the injection molded of the gentle bag cover plate of manufacturing of mould than bigger when the air bag cover plate is on the surface of air bag producer 4 in line of weakness.
In first kind of embodiment, the shape of line of weakness 3 is U types on the air bag cover plate 1, and as shown in Figure 2, promptly air bag cover plate 1 is the line of weakness along the U type when opening, the digging of full wafer.Fig. 3 has represented the track of the line of weakness 3 on the air bag cover plate 1 of another kind of embodiment, is the line of weakness that is the H type with pair of right and left longitudinal component and the lateral part that is connected therewith.Shown in Figure 4 is the shape of the line of weakness 3 of the third embodiment, is the horizontal Y type that two tail ends are connected.The track of different line of weakness generates the requirement of the pressure of gas applicable to the material of different air bag cover plates and gas generator, makes the more accurate and safe upset when airbag-releasing of air bag cover plate, to guarantee the expansion of gasbag.
When line of weakness 3 is positioned on the air bag cover plate 1 air bag producer 4 dorsad surperficial, line of weakness 3 thickness d can be described air bag cover plate thickness D 1/3 to 1/2, as shown in Figure 1, both can guarantee that the air bag cover plate opened accurately under gasbag pressure, can reduce the difficulty of the gentle bag cover plate forming process of manufacturing of mould again, improve the precision of technological process.
The front provides the description to preferred embodiment, so that any technical personnel in this area can use or utilize the utility model.To this preferred embodiment, those skilled in the art can make various modifications or conversion on the basis that does not break away from the utility model principle.Should be appreciated that these modifications or conversion do not break away from protection domain of the present utility model.
