Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to an independent side wing with an airbag and an airbag blasting zone reinforcement structure. Background Art

[0002] Flanking airbags deploy in the event of a collision, preventing serious injuries to occupants and providing more effective collision protection. Currently, a small number of luxury vehicles feature small airbags with a deployment area of 6-8L. With the upgrade of CNCAP standards, independent, deployable side airbags will gradually become mainstream in the market. The standards also explicitly require an increase in the occupant protection area and larger deployment area. This has led to the development of independent, deployable side airbags with larger deployment areas of 14-16L.

[0003] Currently, the automotive industry is committed to improving the safety and comfort of passenger car seats, including the addition of rear airbags. However, due to the structure of most rear seatbacks, there is insufficient space for airbags. Therefore, the idea is to add independent rear side wings to the rear seats of cars, placing airbags within them. This allows the airbags to rapidly inflate and cushion the impact in a collision, thus providing a certain degree of protection for the occupants. This structure not only provides storage space for the airbags, but also ensures their proper deployment and overall support during operation.

[0004] However, due to the increased size of the airbag and the increased impact force, traditional plastic components could no longer meet the required strength, causing plastic components to shatter and fly, potentially injuring occupants. Furthermore, due to the increased volume of the side wing airbag, FEA analysis, using the material curve at -35°C for the wing made of PP / PE-TD5, showed a maximum effective plastic strain of 68.78 MPa, far exceeding the standard 0.13 MPa, posing a significant risk of damage.

[0005] Based on this, the existing side wing structure cannot meet the blasting requirements. It is necessary to strengthen the side wing skeleton structure and develop a new type of independent side wing with airbags to effectively solve the above problems and effectively protect the lives of passengers when the whole vehicle collides. Summary of the Invention

[0006] The purpose of the present utility model is to provide an independent side wing with an airbag and an airbag explosion zone reinforcement structure, strengthen the side wing skeleton structure, solve the problem of meeting the airbag explosion strength requirement, and improve the safety of rear passengers.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] An independent side wing with an airbag and an airbag bursting zone reinforcement structure is connected to the body sheet metal through a side wing sheet metal clip 7, comprising a side wing plastic frame 1, side wing foam 3, side wing protective surface 4, a side wing airbag assembly 5 and an airbag bursting zone reinforcement structure;

[0009] The side wing airbag assembly 5 includes a safety airbag, which is connected to the side wing plastic frame 1 through fasteners; the side wing plastic frame 1 is assembled together with the side wing foam 3; the side wing guard 4 is connected to the plastic frame 1 through the clip strip 2 to achieve overall covering; the airbag explosion zone reinforcement structure is used to protect the side wing plastic frame 1 to prevent the plastic frame from shattering and flying out.

[0010] Furthermore, the side wing plastic frame 1 is an integral supporting structure and is fixed to the vehicle body.

[0011] Furthermore, the side wing foam 3 is filled in the side wing plastic frame 1 to realize that the area in contact with the human body is a soft area.

[0012] Furthermore, the side wing protective surface 4 is in a covering form and covers the outside of the side wing foam 3.

[0013] Furthermore, the fasteners are bolts, airbag nuts and washers 6.

[0014] Furthermore, the airbag explosion zone reinforcement structure is a metal airbag box 9 integrated in the airbag cavity of the wing airbag assembly 5 , and the metal airbag box 9 is connected to the wing airbag assembly 5 through an airbag nut and a gasket 6 .

[0015] Furthermore, the airbag explosion zone reinforcement structure is a fabric hinge structure 8 , which is embedded and injection-molded into the side wing plastic frame 1 .

[0016] Furthermore, the fabric hinge structure 8 is mainly made of nylon, woven into a mesh, and is integrally formed with the side wing plastic frame 1 using an inlay injection molding process.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model strengthens the plastic cavity area structure of the airbag to ensure that the airbag deploys without deformation and the protection area is stable. The optimized airbag has a stable explosion result without fragmentation and flying out. The airbag has independent side wings and has the following specific advantages:

[0019] 1. Safety: This new model features independent side wings with airbags, the first in China to integrate large airbags into side wings. This ensures that rear passenger airbags cover the chest, abdomen, and hip areas, ensuring correct and stable deployment of the airbags, thereby protecting occupants from injury.

[0020] 2. Comfort: Breaking away from the traditional plastic structure of the C-pillar guard, the design utilizes plastic as the skeletal support, foam as the internal filler, and PVC or genuine leather exterior covering. This eliminates the sense of foreign matter when the occupants press against the guard, eliminating the cheap feel and hard texture of hard plastic. The soft foam and leather covering provide a more comfortable experience for the occupants.

[0021] 3. Stability: The product structure is stable, the covering adopts a card strip card connection structure, the assembly adopts a standard metal card structure, and the airbag has an error-proofing function to ensure product quality and durability, help extend product life, and reduce waste and resource waste.

[0030] The seat wings are key automotive interior components and also serve as carriers for airbags. Typically, the independent wings of car seats are primarily supported by a plastic structure, with foam and skin coverings to match the seat's exterior appearance to ensure consistency in the overall vehicle's appearance. Due to the high impact on the main structure of the wing when the airbag explodes, the use of an integral plastic structure carries a high risk of fragmentation and flying out during early design tests and verifications. The present invention studies the manufacturing method and molding mechanism of the coated independent explosion-proof wing, and based on the principle of reducing investment in large-scale slush molding equipment such as molds, conducts structural verification of large-volume airbags and researches and develops the low-temperature performance of materials, designing a new structure that meets the airbag explosion strength requirements.

[0031] The utility model provides an independent wing with an airbag and an airbag bursting zone reinforcement structure, which is connected to the vehicle body sheet metal through a wing sheet metal clip 7 and includes a wing plastic frame 1, wing foam 3, wing protective surface 4, a wing airbag assembly 5 and an airbag bursting zone reinforcement structure.

[0032] The side wing plastic frame 1 is an integral supporting structure and is fixed to the vehicle body.

[0033] The side wing foam 3 is filled in the side wing plastic frame 1 to realize a soft area in the area in contact with the human body, thereby increasing comfort.

[0034] The side wing protective surface 4 is covered on the outside of the side wing foam 3 in a covering form, thereby improving the appearance quality and eliminating the plastic texture.

[0035] The wing airbag assembly 5 includes an airbag, which is connected to the wing plastic frame 1 via fasteners. These fasteners are bolts, airbag nuts, and washers 6. The wing plastic frame 1 is assembled with the wing foam 3. The wing shield 4 is connected to the plastic frame 1 via clips 2, forming a complete cover.

[0036] The airbag blasting area reinforcement structure can be a metal airbag box 9, and the metal airbag box 9 is connected to the wing airbag assembly 5 through an airbag nut and a gasket 6. The utility model adds an airbag box structure 9 to the rear independent wing of the car with an airbag, and uses the metal airbag box 9 to reinforce the structure of the airbag blasting area to protect the wing plastic frame 1 and prevent the plastic frame from breaking and flying out. Based on the passing of the rear independent wing airbag blasting test of the seat, the safety of the rear passengers of the passenger car in the event of a car collision is guaranteed. Specifically, the airbag cavity adopts an assembly method to integrate the metal airbag box. During the airbag blasting process, the metal airbag box is relied on to withstand the airbag blasting force, preventing the wing plastic frame 1 from being deformed by the force and breaking and flying out.

[0037] The airbag blasting zone reinforcement structure can also be a fabric hinge structure 8. The fabric hinge structure 8 is added to the independent rear wing of the car with an airbag, and the fabric hinge structure 8 is embedded and injection-molded into the wing plastic frame 1 to reinforce the structure of the airbag blasting area, protect the wing plastic frame 1, and prevent the plastic frame from shattering and flying out. Based on the passing of the rear seat independent wing airbag explosion test, the safety of rear passengers in passenger cars is guaranteed in the event of a car collision. Specifically, the fabric hinge structure 8 is mainly made of nylon, woven into a mesh, and is molded integrally with the wing plastic frame 1 using an embedded injection molding process. The fabric hinge has high strength, which can enhance the strength of plastic parts in the area covered by the fabric hinge.

[0038] This utility model adds independent rear side wings to the rear seats of the car, and arranges the airbags therein. This enables the airbags to expand rapidly and cushion the impact force when the whole vehicle collides, thereby providing a certain degree of protection for the lives of the passengers in the car. This structure not only provides storage space for the airbags, but also ensures the correct deployment shape of the airbags when the airbags are working and provides overall support for the airbags. Compared with the textured surface design of the plastic parts of ordinary side wings, this side wing adopts foaming and surface lamination technology to improve the comfort and visual effect of the side wings, and improve the appearance and matching requirements of the side wing guards. Compared with other independent side wing assemblies with airbags: other side wing airbags have a liter capacity of 8L; while this product uses an airbag with a liter capacity of 14.5L. The low-temperature airbag explosion requires higher skeleton strength.
