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.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 2 is a schematic structural diagram of the department's logo and the airbag housing in a hot melting state in the embodiment of the present invention, and fig. 3 is an exploded schematic diagram of the department's logo and the airbag housing in the embodiment of the present invention.
As shown in fig. 2 and 3, the airbag housing 21 according to an embodiment of the present invention may include at least one heat stake insertion hole 31. Different with the condition that gasbag housing internal surface flushed in hot melt post jack position and other positions among the prior art, in the embodiment of the utility model provides an, gasbag housing 21 internal surface has bulge 22 at the edge of hot melt post jack 31, and this bulge 22 is link up by hot melt post jack 31. In a specific application, the airbag housing 21 and the protruding portion 22 may be an integral structure or a separate structure. Meanwhile, the thickness of the projection 22 tends to decrease in a direction away from the center of the heat stake insertion hole 31.
It is to be understood that the inner surface of the airbag cover 21 refers to a surface close to the airbag, the direction away from the center of the heat stake insertion hole 31 refers to a direction extending from the center of the heat stake insertion hole 31 toward the edge of the inner surface of the airbag cover 21, and the thickness of the protrusion 22 refers to a distance from a point on the surface of the protrusion 22 to the outer surface of the airbag cover 21. In particular, in the embodiment of the present invention, the trend of decreasing thickness refers to: when detecting the preset area along the preset direction: the thickness is gradually reduced, or the thickness is kept constant in a partial area and gradually reduced in other areas. That is, when the preset region is detected in the preset direction, the thickness is not increased nor is it maintained constant throughout the preset region. It can be understood that, in the present invention, the predetermined direction may be a direction deviating from the center of the heat stake insertion hole 31, and the predetermined region may be a protruding portion 22 region.
Through the design that above-mentioned bulge and thickness are the reduction trend and change, can make department mark hot melt post form the back-off of laminating in the bulge surface after the hot melt to realize the auto-lock when the gasbag explodes.
As a preferable aspect, the protrusion 22 may include: a central plateau 23 at the centre of the bulge and a transition ramp 24 at the edge of the bulge. Wherein the thickness of the transition inclined surface 24 monotonically decreases in a direction away from the center of the heat stake insertion hole 31. The junction of the mid-platform 23 and the transition ramp 24 may be referred to as the mid-platform edge. On the inner surface of the air bag cover 21, the end face of the middle platform 23 contacts and surrounds the edge of the hot melt column insertion hole 31, so that the transition inclined plane 24 is isolated from the hot melt column insertion hole 31. In a specific application, the geometric implementation of the middle platform 23 and the transition bevel 24 may be any form that can form an undercut and provide a self-locking force, for example, the end surface of the middle platform 23 may be a flat surface, and the transition bevel 24 may be a conical surface or a paraboloid surface, etc.
In the embodiment of the present invention, a structure including the airbag housing 21 and the mark is also provided. Generally, at least one heat-melting column 26 is fixed on the specimen body 25, the heat-melting column 26 corresponds to the heat-melting column insertion hole 31 of the airbag housing 21 one by one, can pass through the heat-melting column insertion hole 31 and extend out from the protrusion 22 at the edge of the heat-melting column insertion hole 31, and is fixed with the protrusion 22 in a heat-melting manner. At this time, the melted portion 27 of the heat stake may form an undercut that is attached to the surface of the protrusion 22, thereby achieving self-locking when the airbag is exploded.
Preferably, in the above structure, the melting portion 27 covers the heat stake insertion hole 31 on the inner surface of the airbag housing 21, and the edge of the melting portion 27 does not exceed the surface of the protrusion 22, so that the lack of self-locking force caused by too large range of the melting portion 27 can be avoided on the premise of ensuring the tight connection between the heat stake 26 and the protrusion 22.
In the case of the airbag housing 21 having the middle platform 23 and the transition slope 24, the standard thermal fuse post 26 matched with the middle platform passes through the thermal fuse post insertion hole 31 and extends out of the middle platform 23, and the thermal fuse post 26 and the middle platform 23 are fixed in a thermal fuse mode. At this point, the fused portion 27 of the heat stake 26 forms an undercut that wraps around the edge of the central platform, with the edge of the fused portion 27 at the transition bevel 24. It is understood that coating refers to full coverage. Through the arrangement, the melting part of the hot melting column can be tightly attached to the end face of the middle platform and the transition inclined plane in a more closed mode, and meanwhile, the downward inclination trend of the transition inclined plane can further improve the self-locking force of the reverse buckle. In addition, the melting part does not exceed the transition slope, so that the self-locking force is not lost.
In the embodiment of the present invention, there is further provided a steering wheel for a vehicle using the above structure including an airbag housing and a driver mark, which can be used for any type of vehicle.
It should be understood by those skilled in the art that the above embodiments described in the specification are preferred embodiments and the components and modules involved are not necessarily essential to the practice of the invention.
The utility model discloses among the technical scheme, set up the bulge through the hot melt post jack edge at gasbag housing internal surface, make department mark hot melt post form the back-off of laminating in the bulge surface after the hot melt. When the airbag is exploded, the reverse buckle can form a self-locking function when being subjected to force in the releasing direction, and the larger the releasing force is, the larger the self-locking force is, so that the ejector mark can not be released.
It can be understood that the airbag housing structure of the embodiment of the present invention can be used for housing driver airbag dab (driver air bag), and can also be used for housing other airbags.
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. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
