DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0045] The present invention provides a guide structure for an air curtain 51, such as Figure 1 and Figure 2As shown, the guide member 1 is adapted to be positioned on top of the pillar guard plate 2. The guide member 1 has a guide surface 11 adapted to guide the deployment of the air curtain 51. The included angle A between the guide surface 11 and the vertical direction is in the range of 5 to 45 degrees. The included angle A between the guide surface 11 and the vertical direction of 5 to 45 degrees effectively guides the air curtain 51 to deploy smoothly along the guide surface 11, ensuring that the air curtain 51 fully covers the occupant's head area when deployed, thereby improving safety protection. It should be noted that A can be 5 degrees or 45 degrees.

[0046] The present application sets a guide member 1 on the top of the pillar guard plate 2, and sets the included angle A between the guide surface 11 and the vertical direction to 5 to 45 degrees, which can play a role in guiding the deployment of the airbag, solving the problem of the air curtain 51 being stuck on the B / C pillar guard plate, and solving the problem of the guard plate being shattered by the air curtain 51 and causing splashes. The included angle A between the guide surface 11 of the guide member 1 and the vertical direction is designed to be 5 to 45 degrees, and the guide surface 11 is a downward inclined surface. Then, after the air curtain 51 is detonated, the air curtain 51 deploys downward, and the downward impact component of the air curtain 51 is greater. The air curtain 51 can be deployed quickly and smoothly, improving the protective performance of the air curtain 51. In addition, the impact component of the air curtain 51 on the guide surface 11 is smaller, and the impact force on the guide surface 11 is smaller, so the strength requirements for the pillar guard plate 2 and the guide member 1 are smaller, and the cost of the pillar guard plate 2 and the guide member 1 is lower.

[0047] In one embodiment, Figure 3 As shown, along the length of the vehicle, the guide member 1 has opposing first and second ends 12 and 13, and the pillar guard plate 2 has opposing third and fourth ends 22 and 23, with the third end 22 corresponding to the first end 12 and the fourth end 23 corresponding to the second end 13. A distance D between the first and third ends 12 and 22 is less than or equal to 20 mm, and / or a distance D between the second and fourth ends 13 and 23 is less than or equal to 20 mm. The distance D between the first and third ends 12 and 22 and the distance D between the second and fourth ends 13 and 23 may both be less than or equal to 20 mm, or only the distance D between the first and third ends 12 and 22 may be less than or equal to 20 mm, or only the distance D between the second and fourth ends 13 and 23 may be less than or equal to 20 mm.

[0048] Specifically, during deployment, the airbag can easily penetrate the cavity of the pillar guard plate 2, causing it to become stuck on the pillar guard plate 2 and prevent normal deployment, thereby losing its head protection function. Alternatively, the guard plate may be ruptured by the impact of the air curtain 51, resulting in splashing and injury to the vehicle occupants. This design prevents the air curtain 51 from impacting the ends of the pillar guard plate 2 and preventing it from getting stuck on the guard plate after the air curtain 51 is detonated, allowing the air curtain 51 to deploy normally. Furthermore, this design allows the distance between the guide member 1 and the pillar guard plate 2 to be adjusted within a certain range to accommodate different vehicle models.

[0049] In one embodiment, Figure 3 As shown, along the length of the vehicle, the distance D between the first end 12 and the third end 22 is 15-20 mm, and / or the distance D between the second end 13 and the fourth end 23 is 15-20 mm. Both the distance D between the first end 12 and the third end 22 and the distance D between the second end 13 and the fourth end 23 can be 15-20 mm, or only the distance D between the first end 12 and the third end 22 can be 15-20 mm, or only the distance D between the second end 13 and the fourth end 23 can be 15-20 mm. It should be noted that D can be either 15 mm or 20 mm.

[0050] Specifically, this design prevents the air curtain 51 from impacting the edges of the pillar guard 2 or getting stuck on the guard after detonation, allowing the air curtain 51 to deploy normally. Furthermore, the distance D is greater than or equal to 15 mm, creating a gap between the guide member 1 and the pillar guard 2, facilitating installation. Furthermore, this design allows the distance between the guide member 1 and the pillar guard 2 to be adjusted within a certain range to accommodate different vehicle models.

[0051] In one embodiment, Figure 1 As shown, the pillar guard 2 has a first point 21 closest to the vehicle interior. Along the vehicle's height, a distance B between the bottom of the guide surface 11 and the first point 21 is greater than or equal to 15 mm. First point 21 is the point on the pillar guard 2 closest to the vehicle interior. A distance B between the first point 21 and the bottom of the guide surface 11, along the vehicle's height, of greater than or equal to 15 mm allows for smooth deployment of the curtain airbag 51 and prevents it from impacting the pillar guard 2.

[0052] Specifically, upon detonation, the curtain airbag 51 impacts the guard plate, making it susceptible to drifting inwards to the other side of the head, failing to protect the occupant's head. This design provides ample space for the curtain airbag 51 to deploy, preventing collision or interference with the pillar guard plate 2 during deployment, which could cause deformation or breakage. This allows the curtain airbag 51 to deploy smoothly and protect the occupant's head. Furthermore, this design allows the distance between the bottom of the guide surface 11 and the first point 21 on the pillar guard plate 2 to be adjusted within a certain range to accommodate different vehicle models.

[0053] In one embodiment, Figure 1 As shown, along the height direction of the vehicle, the distance B between the bottom of the guide surface 11 and the first point 21 is 15-20 mm, which allows the air curtain 51 to be deployed smoothly and prevents the air curtain 51 from impacting the pillar guard plate 2. It should be noted that B can be equal to 15 mm or 20 mm.

[0054] Specifically, this design provides sufficient space for the deployment of the curtain airbag 51, preventing collision or interference with the pillar guard plate 2 during deployment, which could cause deformation or breakage of the guard plate. This allows the curtain airbag 51 to deploy smoothly and protect the occupant's head. Furthermore, with B being less than or equal to 20 mm, this design minimizes the overall height of the guide member 1 and pillar guard plate 2, facilitating installation. Furthermore, this design allows for adjustment within a certain range of the vehicle's height between the bottom of the guide surface 11 and the first point 21 on the pillar guard plate 2 to accommodate different vehicle models.

[0055] In one embodiment, Figure 1 As shown, the pillar guard 2 has a first point 21 closest to the interior of the vehicle. Along the width of the vehicle, the bottom of the guide surface 11 is located outside of first point 21. First point 21 is the point on the pillar guard 2 closest to the interior of the vehicle. The fact that the bottom of the guide surface 11 is located outside of first point 21 along the width of the vehicle allows sufficient installation space for the roof 52, preventing the distance between the guide member 1 and the roof 52 from being too narrow, which could affect the normal deployment of the air curtain 51.

[0056] In one embodiment, Figure 1 As shown, the pillar guard 2 has a first point 21 closest to the vehicle interior. Along the vehicle width, the distance C between the bottom of the guide surface 11 and the first point 21 is 0 to 5 mm. First point 21 is the point on the pillar guard 2 closest to the vehicle interior. A distance C of 0 to 5 mm along the vehicle width between the first point 21 and the bottom of the guide surface 11 ensures smooth deployment of the curtain airbag 51 and prevents it from impacting the pillar guard 2. Note that C can be either 0 mm or 5 mm.

[0057] Specifically, upon detonation, the curtain airbag 51 impacts the guard plate, making it susceptible to drifting inwards to the other side of the head, failing to protect the occupant's head. This design prevents the curtain airbag 51 from colliding or interfering with the pillar guard plate 2 during deployment, potentially causing deformation or breakage of the guard plate. This allows the curtain airbag 51 to deploy smoothly and protect the occupant's head. Furthermore, this design allows the distance between the bottom of the guide surface 11 and the first point 21 on the pillar guard plate 2, along the vehicle width, to be adjusted within a certain range to accommodate different vehicle models.

[0058] In one embodiment, the pillar guard plate 2 and guide member 1 are integrally formed. This design utilizes injection molding, stamping, or other suitable manufacturing processes to create a single unitary structure of the pillar guard plate 2 and guide member 1. The guide surface 11 of the guide member 1 seamlessly connects to the top of the pillar guard plate 2, ensuring structural strength and stability.

[0059] Specifically, this design approach means that the pillar guard plate 2 and guide member 1 are produced as a single unit during the manufacturing process, rather than being assembled or connected together later. This one-piece design improves the integrity and stability of the structure, reduces assembly errors, and reduces production costs and assembly time.

[0060] In one embodiment, the pillar guard plate 2 and / or the guide member 1 are constructed of a low-temperature resistant, explosion-proof material. This material selection is intended to enhance the performance and safety of the pillar guard plate 2 and the guide member 1 in extreme environmental conditions, ensuring that the material does not become brittle or fail in low-temperature environments. Furthermore, the material can withstand the impact of high-pressure gas when the air curtain 51 is deployed, preventing rupture or damage.

[0061] In one embodiment, Figure 4 As shown, the guide structure further includes a support structure 3, which is provided on the side of the guide member 1 facing away from the guide surface 11. This design can enhance the structural strength and stability of the guide member 1, ensuring that the guide member 1 can withstand the impact force of the air curtain 51 when the air curtain 51 is deployed while maintaining the stability of its shape and position, thereby improving the reliability of the entire air curtain 51 guide system.

[0062] Specifically, this design ensures that the support structure 3 provides additional support for the guide member 1 without affecting the deployment path of the air curtain 51, so that the guide member 1 has good strength.

[0063] One embodiment, such as Figure 4 As shown, support structure 3 includes reinforcing ribs 31. Ribs 31 have one end connected to the side of guide member 1 facing away from guide surface 11, and the other end connected to pillar guard plate 2. Ribs 31 further enhance the structural strength and stability of guide member 1, ensuring that guide member 1 can withstand the impact of air curtain 51 when deployed while maintaining the stability of its shape and position, thereby improving the reliability of the entire air curtain 51 guide system.

[0064] Specifically, this layout can more evenly disperse the impact force when the air curtain 51 is deployed, thereby improving the overall stability of the guide member 1.

[0065] One embodiment, such as Figure 4 As shown, the spacing between the reinforcing ribs 31 is 15 to 20 mm, and / or the thickness of the reinforcing ribs 31 is 1.5 to 2 mm. This design can reasonably arrange the positions of the reinforcing ribs 31 and further enhance the structural strength and stability of the guide member 1.

[0066] One embodiment, such as Figure 4 and Figure 5As shown, the support structure 3 further includes a support column 32, one end of which is connected to the side of the guide member 1 facing away from the guide surface 11, and the other end of which is connected to the vehicle body 53. This design not only enhances the structural strength and stability of the guide member 1, but also, through the connection with the vehicle body 53, further improves the rigidity and reliability of the entire guide structure, ensuring that the guide member 1 can maintain a stable position and shape when the air curtain 51 is deployed.

[0067] An embodiment of the present invention further provides a pillar guard plate assembly, including a pillar guard plate 2 such as the guide structure of the aforementioned air curtain 51, wherein the pillar guard plate 2 and the guide structure of the air curtain 51 are integrally formed.

[0068] The pillar guard plate assembly integrates the guide structure of the aforementioned air curtain 51, and the pillar guard plate 2 and the guide structure of the air curtain 51 are formed into one piece. This design integrates the guide structure of the air curtain 51 with the pillar guard plate 2, which not only improves the compactness and integrity of the structure, but also ensures the stability and safety of the air curtain 51 when deployed.

[0069] One embodiment, such as Figure 2 and Figure 4 As shown, the pillar guard assembly also includes a pillar guard 2, which is provided with a mounting structure 4 for securing the pillar guard 2 to the vehicle body 53. The pillar guard 2 is secured to the vehicle body 53 via the mounting structure 4, which provides simple assembly and a secure connection, thereby ensuring stability when the vehicle is traveling and the air curtain 51 is deployed, and preventing the pillar guard 2 from falling off due to the impact of the air curtain 51.

[0070] One embodiment, such as Figure 4 As shown, the mounting structure 4 includes a mounting base 4, which is provided with positioning posts 41 for positioning the pillar guard plate 2, and / or reinforcing ribs 31. The positioning posts 41 are used to precisely position the pillar guard plate 2, ensuring its positional accuracy during assembly; the reinforcing ribs 31 are used to enhance the structural strength of the mounting base 4 and improve the stability of the entire mounting structure 4. This comprehensive design not only improves the installation accuracy of the pillar guard plate 2, but also enhances the stability of the mounting structure 4.

[0071] An embodiment of the present invention further provides a vehicle body assembly, including the guide structure of the air curtain 51 as described above, or the pillar guard plate assembly as described above.

[0072] The vehicle integrates the aforementioned air curtain 51 guide structure or pillar guard assembly. This design incorporates the air curtain 51 guide structure or pillar guard assembly as part of the vehicle, aiming to improve vehicle safety, particularly in the event of a collision, ensuring that the air curtain 51 can deploy smoothly and provide protection.

[0073] One embodiment, such as Figure 2As shown, the vehicle body assembly also includes air curtains 51, a vehicle body 53, and a roof 52. The roof 52 is fixed to the vehicle body 53, and the air curtains 51 are positioned in the space between the two. Curtain airbags are installed on both sides of the vehicle's roof. In the event of a severe side collision, the air curtains 51 deploy from the roof 52 along the window, forming a cushion between the occupant and the window, primarily protecting the occupant's head. This design ensures that the air curtains 51 smoothly cover the occupant's head area when deployed, while the fixed structure of the roof 52 provides a stable environment for the deployment of the air curtains 51.

[0074] One embodiment, such as Figure 2 As shown, the pillar guard plate 2 is provided with a limiting portion 24, and at least a portion of the roof 52 is provided within the limiting portion 24 to be installed in conjunction with the pillar guard plate 2. When the air curtain 51 is deployed, the roof 52 is disengaged from the pillar guard plate 2. The limiting portion 24 can be a groove structure for accommodating a portion of the roof 52. The shape and size of the limiting portion 24 are designed to match the edge of the roof 52, and the edge of the roof 52 is partially embedded in the groove structure. This design allows the roof 52 to fit tightly with the pillar guard plate 2 during installation, and at the same time, the roof 52 is easier to open when the air curtain 51 is deployed, and the air curtain 51 has less resistance to deployment and a faster deployment speed.

[0075] One embodiment, such as Figure 2 As shown, a weakened groove 54 is provided in the portion of the roof 52 near the stopper 24 to allow the roof 52 to bend and deform when the air curtain 51 is deployed. When the air curtain 51 is deployed, the roof 52 bends and deforms at the location of the weakened groove 54, separating the roof 52 from the pillar guard plate 2, reducing obstacles to the deployment of the air curtain 51. The air curtain 51 then deploys from this opening to protect the occupant's head.

[0076] Through the above design, a guide member 1 is set on the top of the pillar guard plate 2, and the guide member 1 has a guide surface 11. The angle A between the guide surface 11 and the vertical direction is set to 5~45°. After the air curtain 51 is detonated, the downward impact component of the air curtain 51 is greater, and the air curtain 51 is unfolded along the guide surface 11. The distance D between the first end 12 of the guide member 1 and the third end 22 of the pillar guard plate 2 and the distance D between the second end 13 of the guide member 1 and the fourth end 23 of the pillar guard plate 2 are both within the range of 15~20mm, which can avoid the air curtain 51 from impacting the two end edges of the pillar guard plate 2 and the problem of the air curtain 51 being stuck on the guard plate. The distance B between the bottom of the guide surface 11 and the first point 21 on the pillar guard plate 2 along the vehicle height direction is 15~20mm, and the distance B between the bottom of the guide surface 11 and the first point 21 on the pillar guard plate 2 along the vehicle height direction is 15~20mm. The distance C in the width direction is 0 to 5 mm, which prevents the air curtain 51 from impacting the pillar guard plate 2 and causing the pillar guard plate 2 to break and splash; a support column 32 and a reinforcing rib 31 are provided on the side of the guide member 1 away from the guide surface 11 to ensure that the guide member 1 can withstand the impact force of the air curtain 51 when the air curtain 51 is deployed; the air curtain 51 is arranged in the space between the vehicle body 53 and the roof 52, and the part of the roof 52 close to the limiting portion 24 is provided with a weakening groove 54, and the pillar guard plate 2 is provided with a limiting portion 24, and at least part of the roof 52 is arranged in the limiting portion 24 to cooperate with the pillar guard plate 2 for installation. When the air curtain 51 is deployed, the roof 52 is bent and deformed at the position of the weakening groove 54, so that the roof 52 is separated from the pillar guard plate 2, reducing the obstruction to the deployment of the air curtain 51, and the air curtain 51 is deployed from this opening to protect the occupant's head.

[0077] For the above-mentioned pillar guard plate assembly, body assembly, and vehicle embodiment, they include the guide structure of the aforementioned air curtain 51 and can achieve the same technical effect. To avoid repetition, they will not be described here. For relevant matters, please refer to the partial description of the guide structure embodiment of the air curtain 51.
