Description

Technical Field

[0001] The utility model belongs to the technical field of automotive equipment, and particularly relates to a narrow airbag housing device. Background Art

[0002] An automotive airbag is a passive safety protection device. When used in conjunction with a seat belt, it can provide effective anti-collision protection for the occupants. In a vehicle collision, the airbag can reduce the head injury rate by 25% and the facial injury rate by about 80%.

[0003] In the prior art, the co-pilot airbag is generally installed in the instrument panel. However, with the rapid development of the automotive industry and the emergence of new technologies and new processes, the styling and functional requirements of the instrument panel are getting higher and higher, the screen area is getting larger and larger, but the front-back width and up-down height requirements of the instrument panel are getting smaller and smaller, leaving less and less space for the airbag layout. In a traditional automotive airbag system, the gas generator generally needs to be installed in an additional space below the airbag, which not only limits the flexibility of the vehicle interior design but also increases the installation and maintenance costs.

[0005] The technical solution adopted by the utility model is as follows: A narrow airbag housing device, comprising:

[0006] A housing body, with openings provided at both ends of the bottom along the length direction, and at least two mounting holes provided at a predetermined position of the bottom of the housing body;

[0007] A fixing mechanism, arranged on the inner bottom of the housing body along the length direction for fixedly installing the gas generator; the fixing mechanism includes: a fixing frame, at least two clamps arranged on both sides of the fixing frame, and at least two bolts arranged at the bottom of the fixing frame;

[0008] A clamping structure, arranged on both sides of the top of the housing body;

[0009] At least two upper brackets, arranged at both ends of the upper part of the outer side of the housing body along the length direction;

[0010] At least two lower brackets, arranged at the bottom of the outer side of the housing body along the length direction.

[0011] Preferably, the fixing frame has a concave support part and connecting parts arranged on both sides of the support part.

[0012] Preferably, the clamp is of an annular structure and is arranged on the connecting part.

[0013] Preferably, the engaging structure includes: a plurality of claws arranged at a predetermined distance apart, and reinforcing ribs connecting the claws and the housing body; the number of claws on both sides of the top of the housing body is inconsistent.

[0014] Preferably, the top of the housing body, the upper bracket and the lower bracket are all provided with flanging structures.

[0015] Preferably, locking holes are provided on both the upper bracket and the lower bracket.

[0016] Preferably, the ratio range of the width of the gas generator to the width of the housing body is 1:1.5 to 1:2.5.

[0017] The beneficial effects of the present utility model: Compared with the prior art, the present utility model is provided with a fixing mechanism including a fixing frame and a clamp for realizing the fixed installation of the gas generator inside the housing body, which does not occupy additional space at the bottom of the housing body for installation, not only saves space and simplifies the installation, but also has little impact on the design space of the vehicle interior tube beam, providing more flexibility for the vehicle interior design; the ratio range of the width of the gas generator to the width of the housing body is 1:1.5 to 1:2.5, and a narrower design is adopted to adapt to the space limitation inside the vehicle. The number of claws on both sides of the top of the housing body is inconsistent to prevent the housing from being installed backwards. Description of the Drawings

Detailed Embodiments

[0022] The following further describes the present utility model in conjunction with the specification and embodiments, which can enable those skilled in the art to understand the present utility model more comprehensively, but does not limit the present utility model in any way.

[0023] To solve the technical problems existing in the background art, this embodiment discloses a narrow-type airbag housing device, asFigures 1 to 3 As shown in the figure, it includes: a housing body 1. Openings 2 are provided at both ends of the bottom of the housing body 1 along the length direction to facilitate the routing of the airbag wiring harness. Two mounting holes 3 are provided at a predetermined position on the bottom of the housing body 1 for connecting a fixing mechanism 4; the fixing mechanism 4 is arranged on the inner bottom of the housing body 1 along the length direction for fixedly installing the gas generator; the fixing mechanism 4 includes: a fixing frame 5, at least two clamps 6 arranged on both sides of the fixing frame 5, and two bolts 7 arranged at the bottom of the fixing frame 5; the fixing frame 5 has a concave supporting portion 11 and connecting portions 12 arranged on both sides of the supporting portion 11; the clamp 6 is of an annular structure and is arranged on the connecting portion 12. The gas generator is placed on the supporting portion 11 and then fixed by clamping with the clamp 6. The fixing mechanism 4 is connected to the mounting hole 3 through the bolt 7 to realize the connection with the housing body 1. The fixing mechanism 4 is provided to realize the fixed installation of the gas generator inside the housing body 1 without occupying additional space at the bottom of the housing body 1 for installation, which not only saves space and simplifies the installation, but also has little impact on the design space of the vehicle interior tube beam, providing more flexibility for the vehicle interior design.

[0024] In a further embodiment, a clamping structure 8 is arranged on both sides of the top of the housing body 1; the clamping structure includes: a plurality of claws 13 arranged at a predetermined distance apart, and a reinforcing rib 14 connecting the claws 13 and the housing body 1; the number of claws 13 on both sides of the top of the housing body 1 is inconsistent. The reinforcing rib 14 is used to increase the strength of the claws 13 and reduce deformation. The inconsistent number of claws 13 on both sides of the top of the housing body 1 prevents the front and back installation of the housing from being reversed.
