Description

Technical Field

[0001] This application relates to the fields of automobiles and flying cars, and particularly to an airbag installation structure and an airbag carrier vehicle. Background Art

[0002] At present, common automobiles on the market are all equipped with safety devices. Among them, airbag components are one of the key components of passive safety. Airbag components include: driver airbag, passenger side airbag, side airbag, knee airbag, rear windshield airbag, etc.

[0003] Taking the passenger side airbag as an example, in the instrument panel assembly product structure, a passenger side airbag structure is equipped. An airbag guide frame is correspondingly arranged in the airbag layout area of the instrument panel assembly. The airbag guide frame is arranged between the instrument panel and the airbag housing. The airbag guide frame is provided with an airbag door. During the process of the airbag pop-up, the airbag door drives the area corresponding to the instrument panel to flip open along one side of the flip hinge part, so that the airbag can pop out from the area corresponding to the airbag door to protect the occupants.

[0004] However, the processing cost of the airbag guide frame is high, and the injection molds and inspection tools used in production are costly. The assembly process is complex, and the overall weight of the assembled parts is relatively large. There is an urgent need for a new airbag installation structure to replace the traditional airbag guide frame. Summary of the Invention

[0051] The following further describes the implementation manners of the present disclosure in detail with reference to the drawings and embodiments. The detailed descriptions and drawings of the following embodiments are used to exemplarily illustrate the principles of the present disclosure, but cannot be used to limit the scope of the present disclosure. The present disclosure can be implemented in many different forms, is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0053] It should be noted that in the description of the present disclosure, unless otherwise specified, the meaning of "a plurality" is greater than or equal to two; the orientation or positional relationships indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", etc. are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present disclosure. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0054] In addition, the "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different parts.

[0057] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0058] The airbag guide frame is an important component for connecting the airbag housing and the instrument panel parts. Among them, the airbag guide frame is provided with an airbag door, and the airbag door can be flipped open so that the airbag can pop out from the airbag door area to protect the vehicle occupants.

[0059] However, the production and processing of the airbag guide frame and its assembly with the instrument panel parts result in an increase in cost and an extension of the production period. Especially during the assembly process with the instrument panel parts, a vibration friction welding process is involved, and this welding process also requires the production of specific tooling, leading to a further increase in cost.

[0060] To replace the traditional airbag guide frame with high cost and complex assembly process. This solution proposes a new structure, which not only reduces the production cost and simplifies the assembly process, but also ensures that the airbag can pop out accurately when needed, providing effective protection for the vehicle occupants.

[0061] Embodiment 1

[0062] As Figure 1-2 shown, this application proposes an airbag installation structure, including: a first structural layer 10, an assembly frame structure 20, and a target functional layer 30;

[0063] The first structural layer 10 includes a first surface and a second surface arranged opposite to each other, and the first structural layer 10 includes a weakened area 11;

[0064] The assembly frame structure 20 is disposed on the first surface and is located on the outer peripheral side of the weakened area 11 for connecting the airbag housing 60;

[0065] The target functional layer 30 is disposed on the second surface and is fixedly connected to the first structural layer 10. The target functional layer 30 covers the weakened area 11 of the first structural layer 10. The target functional layer 30 includes a tearing part 31 and a flipping hinge part 32. The position of the weakened area 11 of the first structural layer 10 corresponds to the tearing part 31 and the flipping hinge part 32 of the target functional layer 30. The weakened area 11 of the first structural layer 10 and the tearing part 31 of the target functional layer 30 can be torn under the impact of the airbag, ensuring that the first structural layer 10 and the target functional layer 30 can be accurately torn to form a pop-up window when the airbag is triggered, while the flipping hinge part 32 of the target functional layer 30 does not break or tear, ensuring that the broken part of the first structural layer 10 does not fly out out of control, and can also prevent debris from splashing when the first structural layer 10 is broken, thus ensuring the rapid deployment of the airbag without affecting the safety of the passengers.

[0066] It is understandable that the first structural layer 10 is a basic component of the airbag installation structure, having a certain structural strength to play a role in carrying other components. The first structural layer 10 can be a plane, a curved surface, or other irregular surfaces, such as a wavy surface, etc., and it has two opposite surfaces, a first surface and a second surface.

[0067] The first surface is the back side of the part that is invisible to the vehicle occupants and can also be the side facing the interior of the vehicle, while the second surface is the front side of the part facing the vehicle occupants and can also be the side facing away from the interior of the vehicle. A weakened area 11 is provided on the first structural layer 10, and the weakened area 11 can be used as a specific area for airbag deployment.

[0068] Regarding the installation position of the first structural layer 10, taking an automobile as an example, the airbags included are driver airbags, passenger side airbags, side airbags, knee airbags, rear windshield airbags, etc. The first structural layer 10 can be installed in the corresponding areas to facilitate the installation of airbag assembly parts.

[0069] The assembly frame structure 20 can be arranged on the first surface of the first structural layer 10 and around the weakened area 11, providing one or more fixed connection points, including but not limited to, for connecting the airbag body 70 to the vehicle. It can ensure that the airbag can be deployed in the correct position to maximize its protection effect. Among them, the assembly frame structure 20 can be integrally formed with the first structural layer 10 by injection molding, which can meet the connection strength and improve production efficiency.

[0070] The target function layer 30 is attached to the second surface of the first structural layer 10 and is tightly combined with the first structural layer 10. The setting method of the target function layer 30 and the first structural layer 10 can be compounded on the second surface of the first structural layer 10 through processes such as ultrasonic welding, insert injection molding, secondary injection molding, thermal compounding, laser welding, and bonding.

[0071] The thickness of the target function layer 30 is 0.01 - 3.50 mm.

[0072] Such as Figure 1-4As shown, the target functional layer 30 covers the weakened area 11 of the first structural layer 10. The target functional layer 30 includes a tear portion 31 and a flip hinge portion 32. The weakened area 11 of the first structural layer 10 corresponds to the positions of the tear portion 31 and the flip hinge portion 32 of the target functional layer 30. The target functional layer 30 is tightly connected to the first structural layer 10 to form an integral body, preventing the two from separating after being impacted by the airbag. The weakened area 11 of the first structural layer 10 can be set into a specific path according to requirements by means of injection molding notch weakening, laser weakening, pre-cutting or pre-scoring. The tear portion 31 of the target functional layer 30 can be set into a specific path according to requirements by means of laser weakening, pre-cutting or pre-scoring. When the airbag inflates due to a collision trigger, the weakened area 11 of the first structural layer 10 and the tear portion 31 of the target functional layer 30 can be torn along a predetermined path, thereby forming a window for the airbag to pop out smoothly.

[0073] As Figure 3 (a)(b)(c)(d)(e) shown, the tear portion 31 of the target functional layer 30 can be similar to a U-shape, H-shape, S-shape, single Y-shape or double Y-shape, etc. The setting of the tear portion 31 of the target functional layer 30 ensures that the tear portion 31 of the target functional layer 30 can be torn along a predetermined path when the airbag rapidly inflates. The flip hinge portion 32 of the target functional layer 30 does not break or tear, ensuring that the target functional layer 30 and the first structural layer 10 tightly combined with the target functional layer 30 do not fly out of control, and can also prevent debris from splashing when the first structural layer 10 breaks, thus ensuring the rapid deployment of the airbag without affecting the safety of passengers.

[0074] As Figure 4 (a)(b)(c)(d)(e) shown, there is the first structural layer 10 and the weakened area 11, and the weakened area 11 of the first structural layer 10 corresponds to the positions of the tear portion 31 and the flip hinge portion 32 of the target functional layer 30. The setting of the weakened area 11 of the first structural layer 10 ensures that the weakened area 11 of the first structural layer 10 can be torn along a predetermined path when the airbag rapidly inflates.

[0075] The target functional layer 30 is a single-layer structure or a composite-layer structure; when the target functional layer 30 is a single-layer structure, modified thermoplastic polyolefin or modified thermoplastic elastomer materials, etc. can be used; when the target functional layer is a composite-layer structure, composite materials combining modified thermoplastic polyolefin or modified thermoplastic elastomer materials, etc. with single or multiple types of fibers can be used, and the fiber types include but are not limited to aramid fiber, poly(p-phenylene benzobisoxazole) fiber, carbon fiber, basalt fiber, glass fiber, mixed fiber of aramid fiber and glass fiber, mixed fiber of aramid fiber and basalt fiber, mixed fiber of poly(p-phenylene benzobisoxazole) fiber and aramid fiber, mixed fiber of poly(p-phenylene benzobisoxazole) fiber and glass fiber, and mixed fiber of poly(p-phenylene benzobisoxazole) fiber and basalt fiber materials, etc.

[0076] It can be understood that the thickness of the weakening region 11 provided on the first structural layer 10 is less than the thickness of the first structural layer 10; the thickness of the tearing part 31 provided on the target functional layer 30 is less than the thickness of the target functional layer 30, so that the weakening region 11 and the tearing part 31 can be torn along a predetermined path when impacted by the airbag, thereby forming a clear airbag pop-up window, which helps the airbag to deploy in the expected direction and path, ensuring that the airbag quickly and accurately covers the area to be protected.

[0077] The weakening region 11 is located on the first structural layer 10 and is usually part of the instrument panel or other interior trim parts.

[0078] The first structural layer 10 can form the weakening region 11 by means of injection molding notch weakening, such as setting special geometric shapes (such as V-shaped, U-shaped, trapezoidal grooves, etc.) on the first structural layer 10 to form local thickness reduction in a specific direction, making the tearing path controllable. When the airbag pops up, the first structural layer 10 will preferentially start to tear from these weakening regions 11, thereby forming a regular opening.

[0079] The first structural layer 10 can also process continuous or discontinuous deep holes or shallow holes in the weakening region 11 of the first structural layer 10 by means of laser weakening, making it the weak and easily breakable part of the first structural layer 10.

[0080] The first structural layer 10 can also process cutting lines or indentations in the weakening region 11 of the first structural layer 10 by means of pre-cutting or pre-scoring, making it the weak and easily breakable part of the first structural layer 10.

[0081] When the airbag pops up, the first structural layer 10 will preferentially start to break from the weakening region 11, thereby forming a regular opening on the first structural layer 10.

[0082] The target functional layer 30 can be processed into continuous or discontinuous deep holes or shallow holes in the tear portion 31 of the target functional layer 30 by laser weakening, so that it becomes a weak and easily broken portion of the target functional layer 30 .

[0083] The target functional layer 30 may also be processed into a cutting line or a notch on the tearing portion 31 of the target functional layer 30 by pre-cutting or pre-scoring, so that the tearing portion 31 of the target functional layer 30 becomes a weak and easily broken portion of the target functional layer 30 .

[0084] When the airbag pops out, the target functional layer 30 will first break from the tear portion 31, thereby forming a regular opening on the target functional layer 30. Since the flip hinge portion 32 of the target functional layer 30 is not laser weakened, pre-cut or pre-scored, the target functional layer 30 will not break or tear at the flip hinge portion 32. When the airbag pops out, the flip hinge portion 32 ensures that the target functional layer 30 and the broken portion of the first structural layer 10 do not fly out of control, thereby ensuring that the airbag is deployed quickly without affecting the safety of passengers.

[0085] like Figure 2 As shown, in some embodiments, the target functional layer 30 is connected to the second surface of the first layer structure 10, and the target functional layer 30 protrudes from the second surface of the first layer structure 10 so that the target functional layer 30 and the second surface of the first structure layer 10 meet the non-coplanar condition.

[0086] like Figure 5 As shown, in some embodiments, a groove 12 is formed on the second surface of the first structural layer 10, and the target functional layer 30 is embedded in the groove 12 so that the target functional layer 30 and the second surface of the first structural layer 10 meet the coplanar condition.

[0087] It can be understood that by machining the groove 12 on the second surface of the first structural layer 10 and embedding the target functional layer 30 therein, a seamless combination of the two can be achieved, thereby improving the integrity and aesthetics of the structure.

[0088] The coplanar condition means that the outer surface of the target functional layer 30 and the second surface of the first structural layer 10 are kept on the same surface, so as to ensure that the appearance of the first structural layer 10 (for example, a dashboard or interior decoration, etc.) is flat and smooth, and no abrupt or uncoordinated parts appear due to the existence of the target functional layer 30, thereby improving the user experience. Through the embedded design, the connection between the target functional layer 30 and the first structural layer 10 is tighter, reducing the risk of loosening or falling off.

[0089] The groove 12 can be formed by injection molding, and the groove 12 can be directly formed by a mold when the first structural layer 10 is manufactured.

[0090] The design of the groove 12 can also help fix the position of the target functional layer 30, preventing it from shifting or deforming during long-term use. Common shapes of the groove 12 include rectangular, circular or irregular, and the specific choice depends on the shape and functional requirements of the target functional layer 30. And to further improve the visual effect, patterns, leather grains, or concave-convex texts, letters, logos of companies or institutions, etc. can be set on the target functional layer 30, and different color combinations can also be carried out, so that the target functional layer 30 can have a customizable appearance effect to meet the personalized needs of users.

[0091] As Figure 6 shown, in some embodiments, it further includes: a second structural layer 40, which is disposed on one side of the first structural layer 10 close to the second surface, and is used to cover the target functional layer 30 and the first structural layer 10;

[0092] a third structural layer 50, which is covered on one side of the second structural layer 40 away from the first structural layer 10;

[0093] The second structural layer 40 can form a weak area or an easily torn area with the same shape and corresponding position as the tear part 31 of the target functional layer 30 through laser weakening, pre-cutting, etc.;

[0094] The third structural layer 50 can form a weak area or an easily torn area with the same shape and corresponding position as the tear part 31 of the target functional layer 30 through pre-cutting, etc.;

[0095] The second structural layer 40 is a soft layer with a thickness, and the third structural layer 50 is an epidermal layer.

[0096] It can be understood that in order to take into account the aesthetics, comfort and safety of the airbag installation structure, the second structural layer 40 and the third structural layer 50 are successively added on the first structural layer 10.

[0097] The second structural layer 40 is disposed on one side of the first structural layer 10 close to the second surface, and is mainly used to cover the target functional layer 30 and the first structural layer 10. The second structural layer 40 can be made of a soft material with a thickness (such as polyurethane foam material, polyolefin foam material, three-dimensional fabric material or other elastic materials), and plays a role in buffering, filling and decoration.

[0098] Among them, when the airbag deploys, the second structural layer 40 can act as a soft layer, which can absorb part of the impact force and reduce the harm to passengers. The soft layer can also fill the gap between the first structural layer 10 and the third structural layer 50, making the interior surface smoother. The soft material has certain sound insulation and heat insulation properties, which helps to improve the comfort inside the vehicle. A thicker second structural layer 40 is suitable for scenarios that require higher buffering performance (such as high-end models). A thinner second structural layer 40 is suitable for scenarios with limited space or cost sensitivity (such as economy models).

[0099] For example, in an automotive instrument panel assembly, the second structural layer 40 can cover the target functional layer 30 and the first structural layer 10, forming a smooth transition area to ensure that there are no obvious protrusions or depressions on the interior surface.

[0100] The third structural layer 50 covers the side of the second structural layer 40 facing away from the first structural layer 10 and is usually the skin layer of the vehicle interior (such as leather, fabric, polyvinyl chloride or thermoplastic polyolefin elastomer materials, etc.). It faces directly towards the vehicle occupants and determines the appearance and feel of the interior.

[0101] Among them, the third structural layer 50 can be leather, which is applied to high-end models to provide a luxurious feeling and a soft touch.

[0102] It can also be fabric, which is suitable for economy models and can provide good comfort. It can also be plastic materials such as polyvinyl chloride (PVC) or thermoplastic polyolefin (TPO) that are commonly used for imitating leather effects and have the advantages of low cost and easy cleaning.

[0103] Such as Figure 6 As shown, in some embodiments, it is shown that the weakening area 11 of the first structural layer 10 adopts the injection notch weakening method;

[0104] Such as Figure 7 As shown, in some embodiments, it is shown that the weakening area 11 of the first structural layer 10 adopts the laser drilling weakening method;

[0105] Such as Figure 8 (a)(b) As shown, in some embodiments, the target functional layer 30 is a single-layer structure or a composite layer structure;

[0106] When the target functional layer 30 is a single-layer structure, modified thermoplastic polyolefin or modified thermoplastic elastomer materials, etc. are used;

[0107] When the target functional layer 30 is a composite layer structure, it includes at least one first functional layer 33 and at least one second functional layer 34. The second functional layer 34 is close to the second surface, and the first functional layer 33 is arranged on the side of the second functional layer 34 facing away from the second surface;

[0108] The first functional layer 33 is made of modified thermoplastic polyolefin, modified thermoplastic elastomer material, etc.;

[0109] The second functional layer 34 is made of aramid fiber, poly(p-phenylene benzobisoxazole) fiber, carbon fiber, basalt fiber, glass fiber, mixed fiber of aramid fiber and glass fiber, mixed fiber of aramid fiber and basalt fiber, mixed fiber of poly(p-phenylene benzobisoxazole) fiber and aramid fiber, mixed fiber of poly(p-phenylene benzobisoxazole) fiber and glass fiber, and mixed fiber of poly(p-phenylene benzobisoxazole) fiber and basalt fiber materials, etc.

[0110] When the target functional layer 30 is a composite layer structure, it can also be a multi-layer structure layer with two or more layers, such as three layers, four layers, five layers, etc. For example, when the target functional layer 30 is three layers, the middle layer is the second functional layer 34, and the first layer and the third layer are the first functional layer 33, so that the target functional layer 30 has structural strength and strong flexibility at the same time.

[0111] As Figure 9 shown, in some embodiments, it further includes an airbag housing 60, and the airbag housing 60 is disposed on the first surface and connected to the assembly frame structure 20; the airbag housing 60 forms a receiving space for assembling the airbag body 70 and the gas generator 80, and the notch of the airbag housing 60 faces the first surface and corresponds to the weakening area 11.

[0112] It can be understood that the airbag housing 60 is an important part of the airbag installation structure, which is used to provide an accurate assembly space for the airbag, and at the same time cooperate with the weakening area 11 of the first structural layer 10, the tearing part 31 of the target functional layer 30, the flipping hinge part 32 of the target functional layer 30 and the assembly frame structure 20 of the first structural layer 10 to ensure that the airbag can be deployed along a predetermined path when it pops out.

[0113] The notch of the airbag housing 60 faces the first surface and corresponds to the weakening area 11. The weakening area 11 of the first structural layer 10 corresponds to the positions of the tearing part 31 and the flipping hinge part 32 of the target functional layer 30, so that the airbag can directly pass through the first structural layer 10 and the target functional layer 30 when it pops out, forming a clear airbag exit.

[0114] The airbag housing 60 is connected to the assembly frame structure 20 disposed on the first surface of the first structural layer 10, which can greatly simplify the assembly process.

[0115] Due to the traditional assembly process of the airbag housing 60, which usually adopts the vibration friction welding process, it is necessary to manufacture vibration friction welding molds and vibration friction welding production equipment, greatly increasing the production cost. The welding process requires the input of personnel and time, resulting in a relatively high production cost. Directly connecting the airbag housing 60 through the assembly frame structure 20 of the first structural layer 10 improves the installation efficiency and reduces the production cost.

[0116] Among them, the main function of the airbag housing 60 is to provide a stable assembly space 6 for the airbag. The airbag can be directly ejected from the airbag housing 60. The inner wall of the airbag housing 60 is an integral whole without obstruction, ensuring the timeliness and smoothness of the airbag ejection. The shape of the airbag housing 60 can be adjusted according to the shape of the airbag. Common shapes include rectangular, circular or irregular shapes to meet the requirements of different vehicle models and airbag types.

[0117] As Figure 9 shown, in some embodiments, the end of the airbag housing 60 near the notch abuts against the weakened area 11 of the first structural layer 10.

[0118] It can be understood that during normal use, the weakened area 11 needs to bear a certain pressure, which may cause the weakened area 11 to fail prematurely (such as collapse). By allowing the end of the airbag housing 60 near the notch to abut against the weakened area 11, additional support can be provided for the weakened area 11 to prevent it from collapsing and breaking when under pressure.

[0119] As Figure 9 shown, in some embodiments, the assembly frame structure 20 includes a first clamping structure 21; the airbag housing 60 includes a second clamping structure 61. The first structural layer 10 is connected to the airbag housing 60 through the clamping of the first clamping structure 21 and the second clamping structure 61.

[0120] It can be understood that the clamping structure is a connection method based on the mechanical locking principle. Through the corresponding setting of geometric shapes, rapid assembly and fixation between two components can be achieved. Compared with traditional fixing methods such as bolts, vibration friction welding, and adhesives, the clamping structure does not require additional tools or materials, and can significantly improve the assembly efficiency. In this embodiment, the first clamping structure 21 is provided on the assembly frame structure 20, while the second clamping structure 61 is provided on the airbag housing 60. The two are connected through clamping to realize the connection between the first structural layer 10 and the airbag housing 60, ensuring that the airbag housing 60 is firmly fixed on the first structural layer 10. And the clamping structure realizes the fixed connection through physical locking, has a relatively high tensile strength and anti-vibration ability, and can effectively prevent the airbag module from loosening or falling off during vehicle driving.

[0121] The first clamping structure 21 can be adjacent to the weakening area 11 and placed on the outer peripheral side of the weakening area 11 to avoid blocking the notch of the airbag housing 60.

[0122] Among them, the first clamping structure 21 can form a groove-like structure (such as a card slot or a hole). For the convenience of assembly, the first clamping structure 21 can be provided with a guiding inclined surface to guide the second clamping structure 61 to be smoothly inserted into the groove-like structure and guide the first clamping structure 21 to be smoothly inserted and locked.

[0123] The first clamping structure 21 is made of the same material as the first structural layer 10 (such as modified plastic or composite material) to ensure the consistency and durability of the overall structure.

[0124] The second clamping structure 61 can be a convex structure located on the outer peripheral side edge of the airbag housing 60, corresponding to the first clamping structure 21.

[0125] The second clamping structure 61 can be a convex structure (such as a buckle or a boss) for inserting or locking into the first clamping structure 21.

[0126] And in order to achieve rapid assembly, the second clamping structure 61 can adopt an elastic arm, so that it generates elastic deformation when inserted and then returns to its original state to complete the locking.

[0127] It should be noted that the first clamping structure 21 can be a convex structure (such as a buckle or a boss), and the second clamping structure 61 can be a groove-like structure (such as a card slot or a hole). And in order to further improve the connection stability between the airbag housing 60 and the first structural layer 10, the first clamping structure 21 includes both a convex structure and a groove-like structure, and is arranged at intervals and staggered on the outer peripheral side of the weakening area 11 to improve the fixing effect. The second clamping structure 61 corresponds to the first clamping structure 21 and includes both a groove-like structure and a convex structure, is arranged at the notch of the airbag housing 60, and is arranged at intervals and staggered on the outer peripheral side of the notch.

[0128] For the convenience of assembly, the second clamping structure 61 can be designed with a guiding inclined surface to guide the first clamping structure 21 to be smoothly inserted and locked.

[0129] Such as Figure 9 As shown, in some embodiments, the first clamping structure 21 extends in a direction away from the second surface, and the first clamping structure 21 includes a card slot and / or a claw; the second clamping structure 61 is correspondingly provided with a claw and / or a card slot;

[0130] Among them, the clamping connection between the first clamping structure 21 and the second clamping structure 61 is realized by the cooperation of the card slot and the claw.

[0131] It can be understood that the card slot is a recessed structure for receiving the claw and providing space for locking. The claw is a protruding structure (usually with elasticity or barbs) for inserting into the card slot and forming a physical lock.

[0132] Through the cooperation of the card slot and the claw, rapid assembly and firm connection between two components can be achieved.

[0133] The first latching structure 21 extends in a direction away from the second surface to ensure that it can be correctly aligned with the second latching structure 61 on the airbag housing 60 and complete the latching.

[0134] The cooperation of the card slot and the claw requires no additional tools or materials, which can significantly improve the assembly efficiency. And it has a high tensile strength, which can effectively prevent the airbag housing 60 equipped with the airbag from loosening or falling off during vehicle driving.

[0135] Among them, the first latching structure 21 can be in the shape of a groove for receiving the claw of the second latching structure 61; the first latching structure 21 can also be in the shape of a protrusion (such as an elastic arm or barbs) for inserting into the card slot of the second latching structure 61; the first latching structure 21 can also include both a card slot and a claw at the same time to meet more complex connection requirements.

[0136] Similarly, the corresponding second latching structure 61 can be in the shape of a protrusion (such as an elastic arm or barbs) for inserting into the card slot of the first latching structure 21; the second latching structure 61 can also be in the shape of a groove for receiving the claw of the first latching structure 21. The second latching structure 61 can also include both a card slot and a claw at the same time, which are arranged at intervals and staggered to meet the connection requirements and improve the stability after connection.

[0137] As Figure 10 shown, in some embodiments, a plurality of second latching structures 61 are circumferentially and spacedly arranged on the side wall of the airbag housing 60 to achieve the latching of the first latching structure 21 of the airbag housing 60 and the assembly frame structure 20. It can be understood that through the assembly frame structure 20 on the first structural layer 10, a firm and rapid connection between the first structural layer 10 and the airbag housing 60 is achieved.

[0138] The opening shape of the assembly port of the assembly frame structure 20 corresponds to that of the notch of the airbag housing 60, and the diameter of the assembly port of the assembly frame structure 20 is larger than that of the notch of the airbag housing 60. Corresponding guiding structures such as slides, chutes, and guiding inclined surfaces can be provided inside the assembly port of the assembly frame structure 20 and outside the notch of the airbag housing 60, which is conducive to the accurate and rapid assembly of the airbag housing 60 and the assembly frame structure 20.

[0139] The connection relationship between the assembly frame structure 20 and the airbag housing 60 is modular, making the entire airbag module assembly structure more compact, stable and easy to assemble.

[0140] As Figure 10 shown, in some embodiments, triangular reinforcing ribs 22 are provided on the outer peripheral side of the assembly frame structure 20. Two adjacent sides of the reinforcing ribs 22 are respectively abutted against the outer side wall of the assembly frame structure 20 and the first surface of the first structural layer 10;

[0141] The airbag housing 60 is assembled into the assembly frame structure 20 so that the notch is adjacent to the first surface. There may be no gap or a gap of 0.1 mm to 1.5 mm is provided between the outer side wall of the airbag housing 60 and the inner side wall of the assembly frame structure 20. It can be understood that the triangular reinforcing ribs 22 are provided on the outer peripheral side of the assembly frame structure 20, which can significantly enhance the overall rigidity and anti-deformation ability of the assembly frame structure 20. Two adjacent sides of the reinforcing ribs 22 are respectively abutted against the outer side wall of the assembly frame structure 20 and the first surface of the first structural layer 10, forming a stable support structure to prevent the assembly frame structure 20 from bending or collapsing during long-term use or under external forces.

[0142] Embodiment Two

[0143] As Figure 9-11 shown, the present application proposes a safety airbag carrier, including the airbag mounting structure and the airbag housing 60 proposed in Embodiment One. The airbag housing 60 is disposed on one side of the first surface of the first structural layer 10 of the airbag mounting structure.

[0144] It can be understood that the installed airbag carrier includes the airbag mounting structure and the airbag housing 60 mentioned in the first aspect. The airbag housing 60 is assembled with the assembly frame structure 20 on the first surface of the first structural layer 10 of the airbag mounting structure. The airbag housing 60 is formed with a receiving space for assembling the airbag body 70 and the gas generator 80. The notch of the airbag housing 60 faces the first surface and corresponds to the weakening area 11.

[0145] The airbag mounting structure, as a modular component, can be independently produced and tested, and then integrated with vehicle components (such as instrument panels, knee pads, etc.), which is convenient for subsequent maintenance and replacement.

[0146] The airbag housing 60 is usually made of reinforced modified nylon material, or reinforced modified polypropylene material, or reinforced modified nylon material combined with unidirectional woven fiber-reinforced polyamide ribbon material, or reinforced modified polypropylene material combined with unidirectional woven fiber-reinforced polypropylene ribbon material, etc., and has good mechanical strength and impact resistance.

[0147] The airbag body 70 is usually made of high-strength fabric (such as nylon or polyester fiber), and has good tear resistance and high-temperature resistance characteristics. The internal inflation device (such as the gas generator 80) can generate a large amount of gas in a very short time, causing the airbag to quickly expand and deploy.

[0148] When the airbag is triggered, the airbag body 70 quickly pops out of the airbag housing 60. The weakening area 11 of the first structural layer 10 and the tearing part 31 of the target functional layer 30 can be torn under the impact of the airbag, ensuring that when the airbag is triggered, the first structural layer 10 and the target functional layer 30 can accurately tear to form a pop-up window, and the flipping hinge part 32 of the target functional layer 30 does not break or tear, ensuring that the broken part of the first structural layer 10 does not fly out out of control, and can also prevent debris from splashing when the first structural layer 10 is broken, so as to ensure the rapid deployment of the airbag without affecting the safety of passengers.

[0149] As Figure 10-12 shown, the second clamping structure 61 on the airbag housing 60 is clamped with the first clamping structure 21 of the assembly frame structure 20. As Figure 10 shown, there can be 3 second clamping structures 61 in each first clamping structure 21; as Figure 11 shown, there can be 2 second clamping structures 61 in each first clamping structure 21; as Figure 12 shown, there can be 1 second clamping structure 61 in each first clamping structure 21; it can be understood that there can be a number of second clamping structures 61 in each first clamping structure 21 including but not limited to one and more than one. The clamping structures at multiple positions of the second clamping structure 61 of the airbag housing 60 and the first clamping structure 21 of the assembly frame structure 20 make the installation structure of the entire airbag module assembly more stable and safe.

[0150] The present application provides an airbag installation structure and a safety airbag vehicle that can be applied to areas such as the instrument panel and knee baffle of automobiles and flying automobiles, and cooperate with the safety airbag to provide collision protection for drivers and passengers. Taking an automobile as an example, the present application provides an airbag installation structure and a safety airbag vehicle that can be applied to the passenger side area of the instrument panel, and cooperate with the safety airbag to provide head collision protection for passengers; it can also be applied to the knee baffle area on the driver side and / or passenger side, and cooperate with the safety airbag to provide knee collision protection for the driver and / or passenger.

[0151] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
