Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to automotive front bumper curtain airbags. Background Technology

[0002] The front bumper of the car features perforated air curtains on both sides, which not only create a visually striking effect but also significantly improve aerodynamic performance. The function of the front bumper air curtain is to guide airflow, directing it through the air intakes into channels on the inside of the bumper and towards the outside of the wheels. This smooths the airflow around the wheels, reducing wind resistance and thus minimizing drag. Typically, the front bumper air curtain and headlights are separate, with no matching relationship, resulting in a relatively monotonous air curtain design. However, with increasingly sharp styling from automakers, headlights are now integrated into the air curtain, creating a unified look. While this structure is novel and unique, the complex headlight structure and large space required, combined with the need to fit the air curtain into the front bumper, present a significant technical challenge in designing the air curtain within these space constraints. Summary of the Invention

[0003] The purpose of this utility model is to provide a front bumper curtain airbag for automobiles, which addresses the problems encountered in practice as described above.

[0004] The technical solution adopted in this utility model is as follows:

[0024] like Figure 1 and Figure 2As shown, the present invention relates to a front bumper curtain airbag for automobiles, comprising a skin 1, an outer panel 2, a bracket 3, an inner panel 4, and a headlight assembly. The skin 1 corresponds to the outer contour of the bracket 3 and has a bracket window 11, which is fixed to the vehicle body. The outer panel 2 corresponds to the outer contour of the headlight head end (front end) and has a headlight window 21 and a passage opening 22. The bracket 3 corresponds to the outer contour of the outer panel 2 and has an outer panel window 31 and a passage side panel 32. The inner panel 4 has a bracket connection structure 1 41, a skin connection structure 42, and a bracket connection structure 2. 43. Outer panel connection structure; 44. Diverter rib; 45. Bending edge; 46. The headlight assembly includes a headlight 7, a lamp holder 1 5, and a lamp holder 2 6 installed together and mounted on the vehicle body. The skin 1, outer panel 2, bracket 3, and inner panel 4 are fixedly connected by conventional installation methods. Considering the characteristics of plastic components, methods such as welding, screw connections, and snap-fit ​​connections are used to ultimately form the air curtain channel 8 of this invention. In this embodiment, to make their connection more secure or convenient, corresponding interconnecting structures are provided. See [link to relevant documentation]. Figure 3-5 As shown, the bracket 3 is fixedly connected to the skin 1 by welding, and its front end is positioned in the bracket window 11 of the skin 1 that matches its shape. The outer panel 2 is fixedly connected to the bracket 3 by welding and snap fasteners, and its front end is positioned in the outer panel window 31 of the bracket 3 that matches its shape. See [reference needed] Figure 6-10 As shown, in this embodiment, the inner plate 4 uses screws that are easy to disassemble and maintain. It is fixedly connected to the channel side plate 32 of the bracket 3 by the bent edge 46 through the bracket connection structure 41 and the bracket connection structure 43. Together with the channel side plate 32 of the bracket 3, it forms part of the channel 8. Its skin connection structure 42 is fixedly connected to the skin 1 through its corresponding connection structure, and its outer plate connection structure 44 is fixedly connected to the outer plate 2 through its corresponding connection structure. The inner plate 4 is fixedly connected to the existing skin 1, outer plate 2, and support 3, further strengthening the stability of the connection and support of each component. The flat channel 8 formed has a smooth overlap between the outer plate 2 and the skin 1, support 3, and inner plate 4 at its entrance, sides, and upper and lower parts. The smooth overlap with the skin 1 also creates a smooth and novel appearance. A sponge strip 9 is fixedly pasted to the end of the bent edge 46 of the inner plate 4. Its function is to fix the sponge strip 9 between the bent edge 46 of the inner plate 4 and the support 3 after installation, so that the inner plate 4 and the support 3 make soft contact and form a seal at the upper and lower parts of the channel 8, which is conducive to forming a complete and unobstructed channel 8.
