Abstract
The utility model discloses a connecting structure of an automobile passenger safety air bag and an instrument panel, which is characterized in that abnormal noise prevention brackets are respectively arranged on the lateral surfaces of both ends of a safety air bag shell; two lower mounting brackets are arranged on the lower surface of the safety air bag shell; mounting holes are respectively formed in the lower surfaces of both ends of an instrument panel air bag frame; metal sheet nuts are respectively clamped on the two mounting holes; the upper ends of the two abnormal noise prevention brackets on the safety air bag shell are respectively connected with the two metal sheet nuts on the instrument panel air bag frame by fastening screws; and the two lower mounting brackets on the lower surface of the safety air bag shell are respectively and fixedly connected with a steering support. According to the utility model, the instrument panel air bag frame is connected with the instrument panel by a friction welding process, the lower part of the safety air bag shell is connected and fixed together with the steering support by the two lower mounting brackets and the upper parts of the safety air bag shell are connected and fixed together with the instrument panel air bag frame by the two abnormal noise prevention brackets, and thus, the free motion of the safety air bag is limited and the problem of abnormal noise caused by the shaking of the safety air bag is effectively solved.
Description
Technical field
The utility model relates to the automobile component connection structure, is specifically related to the connection structure of a kind of vehicle occupant safety air bag and instrument carrier panel.
Background technology
At present, on most car, all be equipped with passenger airbag, passenger airbag generally has two kinds with the connection mode of instrument carrier panel: bolted connection is connected with hook.Bolt connecting mode is to make attachment face in the safety airbag casing both sides, directly captives joint with instrument carrier panel through bolt, does not have relative motion between safety air bag and the instrument carrier panel.The hook connection mode then is to do row's hook in the safety airbag casing both sides, is connected with instrument carrier panel through hook; So there is certain tolerance clearance in this kind connection mode owing to will consider assembling between the hook of air bag and the instrument carrier panel, comparatively jolt in addition abominable operating mode under, safety air bag may be owing to rocking and the airbag housing collision produces abnormal sound.For this type of abnormal sound, can on hook, increase felt, to reduce abnormal sound, asking of assembling is inconvenient inscribes but bring thereupon.
Summary of the invention
The purpose of the utility model provides the connection structure of a kind of vehicle occupant safety air bag and instrument carrier panel, and this connection structure can avoid passenger airbag to produce abnormal sound by actv., and simple in structure, and cost is lower.
The connection structure of described a kind of vehicle occupant safety air bag of the utility model and instrument carrier panel is characterized in that: on the safety airbag casing side faces at both ends, be respectively equipped with anti-abnormal sound support, below safety airbag casing, be provided with two following mounting brackets; Below instrument carrier panel air bag frame two ends, be respectively equipped with mounting hole, be connected with the sheetmetal nut respectively on these two mounting holes;
The upper end of two anti-abnormal sound supports on the safety airbag casing is connected with two sheetmetal nuts on the instrument carrier panel air bag frame through tightening screw respectively; Two following mounting brackets below the safety airbag casing are connected with turning to support fixation respectively.
Further, said two anti-abnormal sound supports are for being the sheetmetal of " Z " shape, the lower end of two anti-abnormal sound supports respectively through impact style and safety airbag casing be located by connecting, the upper end is respectively equipped with screw fixed hole.
Further, be respectively equipped with reinforced rib and flange on said two anti-abnormal sound supports.
The utility model is compared with prior art and is had the following advantages: because instrument carrier panel air bag frame is connected with instrument carrier panel through friction welding technological; The safety airbag casing bottom is through two following mounting brackets and turn to support and connection to fix; Top is connected fixing with instrument carrier panel air bag frame through two anti-abnormal sound supports; Like this, the free activity of restriction safety air bag, actv. solves and rocks the abnormal sound that causes by safety air bag.
Description of drawings
Fig. 1 is the structural representation of passenger airbag.
Fig. 2 is the structural representation of instrument carrier panel air bag frame.
Fig. 3 is the assembling scheme drawing of passenger airbag and instrument carrier panel air bag frame.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1 and Fig. 2; The connection structure of described a kind of vehicle occupant safety air bag of the utility model and instrument carrier panel; The characteristics of its connection structure are: on safety airbag casing 3 side faces at both ends, be respectively equipped with anti-abnormal sound support 2, below safety airbag casing, be provided with two following mounting brackets 4; Below instrument carrier panel air bag frame 6 two ends, be respectively equipped with mounting hole 5, be connected with sheetmetal nut 7 respectively on these two mounting holes;
Said two anti-abnormal sound supports 2 are for being the sheetmetal of " Z " shape, the lower end of two anti-abnormal sound supports respectively through impact style and safety airbag casing 3 be located by connecting, the upper end is respectively equipped with screw fixed hole.Be respectively equipped with reinforced rib and flange on said two anti-abnormal sound supports 2.
Referring to Fig. 3; During installation; At first two row's hooks with safety air bag 1 collude in the instrument carrier panel air bag frame 6; It is fixing, last to prevent that with tightening screw 8 and sheetmetal nut 7 abnormal sound support 2 is connected with instrument carrier panel air bag frame 6 again, and two following mounting brackets 4 below the safety airbag casing 3 are supported 10 and are connected and fix with turning to.Owing to be provided with anti-abnormal sound support, the top of safety air bag to be fixed, safety air bag can not rock, and abnormal sound disappears.
