Detailed Description
Exemplary embodiments of the invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1 to 3, an embodiment of the present invention provides an airbag cover, including: an outer layer 1, an intermediate layer 2 and an inner layer 3; one surface of the middle layer 2 is fixedly connected with the outer layer 1, and the other surface of the middle layer 2 is fixedly connected with the inner layer 3.
The middle layer 2 can be fixedly connected with the outer layer 1 and the inner layer 3 in various ways, for example, the middle layer 2 is injection molded between the outer layer 1 and the inner layer 3, or the middle layer 2 is integrally formed with the outer layer 1 and the inner layer 3. In fig. 1 to 3, a-a is a sectional direction of fig. 1, and B indicates an enlarged portion of fig. 2.
Taking the case that the intermediate layer 2 is injection molded between the outer layer 1 and the inner layer 3 as an example, when the airbag cover is produced, a secondary injection molding mode can be adopted, the outer layer 1 or the inner layer 3 of the airbag cover is formed by first injection molding, then the intermediate layer 2 is added on the outer layer 1 or the inner layer 3 formed by first injection molding, and the other part of the airbag cover is formed by second injection molding, that is, when the outer layer 1 is formed by first injection molding, the inner layer 3 is formed by second injection molding, when the inner layer 3 is formed by first injection molding, the outer layer 1 is formed by second injection molding, and the airbag cover after injection molding is shown in fig. 4 and fig. 5, wherein C indicates an enlarged part of fig. 4.
From this, form intermediate level 2 between outer 1 of air bag lid and inlayer 3 through twice moulding plastics, increased the cushioning nature of air bag lid for air bag lid is when the bag show, and inner 3 and outer 1's reinforcement can be regarded as to intermediate level 2, avoids air bag lid to scatter, and then has improved the security of car air bag system.
In order to improve the connection tightness between the intermediate layer 2 and the outer layer 1 and the inner layer 3, as shown in fig. 6 to 8, in one embodiment of the present invention, one surface of the intermediate layer 2 is the same as the inner shape of the outer layer 1, and the other surface of the intermediate layer 2 is the same as the outer shape of the inner layer 3. For example, the surface of the intermediate layer 2 connected to the outer layer 1 is formed to have the same shape as the inner shape of the outer layer 1, and the surface of the intermediate layer 2 connected to the inner layer 3 is formed to have the same shape as the outer shape of the inner layer 3, that is, the surface of the intermediate layer 2 connected to the outer layer 1 has a contour structure inside the outer layer 1, and the surface of the intermediate layer 2 connected to the inner layer 3 has a contour structure outside the inner layer 3.
In order to facilitate the production of air bag lid, in an embodiment of the utility model, as shown in fig. 9, the thickness of intermediate level 2 is even, that is to say, the intermediate level can be the even platelike structure of a layer thickness, carries out the secondary again with it after adding between skin 1 and inlayer 3 and moulds plastics, reduces the production degree of difficulty of air bag lid.
In an embodiment of the present invention, the intermediate layer 2 may also be a mesh structure, and the mesh structure may be made of metal, that is, the intermediate layer 2 may be a mesh structure made of metal. It is understood that, in order to ensure the strength and cushioning effect of the intermediate layer, the metal forming the net structure may be a metal having a relatively high strength, such as iron, copper, titanium, and the like. In addition, in consideration of the manufacturing process and the cushioning effect of the intermediate layer 2, these metals are often used to manufacture the intermediate layer in the form of an alloy, and for example, the intermediate layer may be made of a titanium alloy, so that the intermediate layer 2 is resistant to high and low temperatures and has high strength.
In addition, the intermediate layer 2 may also be a net-shaped structure or a plate-shaped structure made of other existing materials resistant to high and low temperatures, high strength and high tensile strength, and in an embodiment of the present invention, the intermediate layer 2 is a net-shaped structure or a plate-shaped structure made of silicone rubber.
It will be understood that when the intermediate layer 2 is of a plate-like structure, it may be of a plate-like structure of uniform thickness, or may be of a plate-like structure having a profile structure on both sides (one side being the profile structure of the outer layer 1 and the other side being the profile structure of the inner layer 3).
As shown in fig. 2, 4, 6 and 10, in order to facilitate the connection of the airbag cover to the external bag receiving device, in one embodiment of the present invention, the outer layer 1 includes a connecting portion 11, through which the connecting portion 11 is engaged with the bag receiving device, and the airbag cover can be engaged with the bag receiving device.
As shown in fig. 3, in an embodiment of the present invention, the inner layer 3 includes an inner concave portion 31, and the inner concave portion 31 is fixedly connected with the outer layer 1. Through the direct connection of the concave part 31 and the outer layer 1, namely, the middle layer 2 does not exist between the concave part 31 and the outer layer 1, when the airbag is inflated and unfolded, the local area of the airbag cover where the concave part 31 is located is broken, and the airbag is convenient to unfold.
In conclusion, according to the utility model discloses technical scheme forms the air bag lid through twice moulding plastics, moulds plastics for the first time and forms the skin or the inlayer of air bag lid, then adds the one deck intermediate level on the skin or the inlayer that form of moulding plastics for the first time, forms inlayer or skin through moulding plastics for the second time again. From this, form the intermediate level through twice moulding plastics between the skin of air bag lid and inlayer, increased the buffer nature of air bag lid for air bag lid is when the bag show, and the intermediate level can regard as inlayer and outer reinforcement, avoids air bag lid to scatter, and then has improved the security of car air bag system.
The above detailed description does not limit the scope of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors.
