Description

Technical Field

[0001] This utility model belongs to the technical field of automobile manufacturing, and in particular relates to a lower spoiler with a shrink-proof inverted positioning structure. Background Technology

[0002] Automotive spoilers are an important component of automobiles. Their main functions are to reduce air resistance, improve vehicle stability, enhance the vehicle's appearance, and reduce wind noise. Currently, the outer and inner panels of lower spoilers on the market require the addition of positioning ribs in the Y-direction (left-right direction) for Y-axis positioning during installation to ensure accurate installation. However, the positioning ribs on the market are currently all located on the end face of the outer panel, which often leads to shrinkage issues in the lower spoiler's appearance, affecting the pass rate of qualified products. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide a lower spoiler with a shrinkage-avoidance inverted positioning structure, which is used to set the positioning rib on the flange of the outer plate of the lower spoiler, thereby avoiding the appearance shrinkage problem caused by the positioning rib growing directly on the large surface of the outer plate of the lower spoiler.

[0004] This utility model provides a lower spoiler with a shrink-avoidance snap-lock positioning structure, including an outer lower spoiler plate and an inner lower spoiler plate. The bottom of the outer lower spoiler plate is provided with a flange facing the inner lower spoiler plate. The bottom of the inner lower spoiler plate is mounted on the flange of the outer lower spoiler plate. A positioning rib is provided in the middle of the flange at the bottom of the outer lower spoiler plate. The bottom of the inner lower spoiler plate is provided with a snap-lock groove corresponding to the positioning rib. The snap-lock groove of the inner lower spoiler plate engages with the positioning rib, so that the outer lower spoiler plate and the inner lower spoiler plate are positioned in the Y direction.

[0005] As a preferred embodiment of this utility model, the positioning rib is a rectangular protrusion, and the positioning rib is integrally formed with the flange of the outer plate of the lower spoiler.

[0006] As a preferred embodiment of this invention, the inverted snap-fit ​​groove is a U-shaped groove.

[0007] The beneficial effects of this utility model are as follows:

[0008] 1. This utility model adopts a Y-direction positioning rib with an inverted structure and sets the positioning rib on the flange of the outer plate of the lower spoiler. The problem of shrinkage in appearance is solved by avoiding the positioning rib from growing directly on the large surface.

[0009] 2. This utility model has the advantages of simple and reliable structure and low appearance defect rate. Attached Figure Description

[0017] The attached reference numerals include: lower spoiler outer plate 1, lower spoiler inner plate 2, flange 3, positioning rib 4, and inverted snap-fit ​​groove 5. Detailed Implementation

[0018] See Figure 1-6 As shown, this embodiment provides a lower spoiler with a shrink-avoidance snap-on positioning structure, including a lower spoiler outer plate 1 and a lower spoiler inner plate 2. The bottom of the lower spoiler outer plate 1 is provided with a flange 3 facing the lower spoiler inner plate 2. The bottom of the lower spoiler inner plate 2 is mounted on the flange 3 of the lower spoiler outer plate 1. A positioning rib 4 is provided in the middle of the flange 3 at the bottom of the lower spoiler outer plate 1. A snap-on groove 5 is provided at the bottom of the lower spoiler inner plate 2 corresponding to the position of the positioning rib 4. The snap-on groove 5 of the lower spoiler inner plate 2 is engaged with the positioning rib 4, so that the lower spoiler outer plate 1 and the lower spoiler inner plate 2 are positioned in the Y direction.

[0019] Furthermore, in this embodiment, the positioning rib 4 is a rectangular protrusion, and the positioning rib 4 is integrally formed with the flange 3 of the lower spoiler outer plate 1. The height ratio of the positioning rib 4 of the lower spoiler outer plate 1 to the width ratio of the flange 3 is 2.7:8, which satisfies the mold strength requirement that the width-to-depth ratio is greater than 1 / 3.

[0020] Working principle: The positioning rib 4, which affects the shrinkage problem of the lower spoiler outer plate 1, is installed on the bottom flange 3 of the lower spoiler outer plate 1, thereby ensuring the Y-direction positioning requirements and completely solving the shrinkage problem of the lower spoiler outer plate 1.

[0021] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
