Technical Field
[0001] The utility model relates to the technical field of automobile exterior plastic parts, in particular to a vehicle door guard plate structure. Background Art
[0002] The inner and outer panels of the door guard plate will inevitably deform after injection molding. After assembly, due to the lack of limiting structures to constrain each other, the lower edge of the assembly will bulge outward and have step differences, affecting the appearance.
[0003] Usually, to solve this kind of problem, it is necessary to set a snap connection structure on the outer panel and the inner panel.
[0004] However, the snap-on structure occupies a large space, is difficult to produce molds, is costly, and after injection molding, defects will occur on the exterior surface corresponding to the snap-on position of the product (known in the industry as shrinkage), which is not allowed for automotive exterior decorative parts. Utility Model Content
[0005] The purpose of the utility model is to provide a vehicle door guard plate structure, which solves the problem that the existing vehicle door guard plate inner and outer plates are provided with a snap connection structure, the mold production is difficult and costly, and the appearance surface corresponding to the position of the product's clip foot will have defects after injection molding.
[0006] To achieve the above-mentioned purpose, the utility model provides a vehicle door guard plate structure, including an inner plate and an outer plate, the inner plate having a groove, the groove being located at the lower edge of the inner plate, the outer plate having a first protrusion, the first protrusion being located on the wall thickness of the lower edge of the outer plate and cooperating with the groove.
[0007] The inner plate further has a first reinforcing plate, and there are multiple first reinforcing plates, which are respectively located above the grooves.
[0008] The inner plate further has a second reinforcing plate, and there are multiple second reinforcing plates, which are respectively distributed along the horizontal direction of the lower edge of the inner plate.
[0009] Wherein, the inner plate further has a second protrusion, and the second protrusion is located below the first protrusion.

[0011] The present invention provides a vehicle door guard plate structure, wherein the grooves of a specific size are evenly arranged on the lower edge of the inner plate, and the first protrusions are evenly arranged on the wall thickness of the lower edge of the outer plate. After the inner and outer plates are assembled, the concave and convex structures on the lower edges constrain each other to achieve a snap-fitting effect, thereby eliminating the inevitable deformation of the inner and outer plates of the vehicle door guard plate after injection molding. After assembly, due to the lack of a limiting structure to constrain each other, the lower edge of the assembly may implode or have a step difference, affecting the appearance. The snap-fitting structure is simpler, more effective, and more compact, and can be arranged in a small space, saving space; it reduces the difficulty of mold production and reduces production costs; it solves the problem of deformation of plastic parts leading to poor appearance and size after assembly; it avoids appearance defects of plastic parts; and it greatly improves the market core competitiveness of automobile door guard plates.

The above-mentioned solution solves the problem that a snap connection structure is provided on the inner and outer plates 102 of the existing vehicle door guard plate, the mold is difficult to make, the cost is high, and the appearance surface corresponding to the position of the product's clip foot after injection molding will have defects. It can be understood that the above-mentioned solution can also be used in any field of assembly between plastic parts.
[0022] In this specific embodiment, the inner panel 101 has a groove 103 located at the lower edge of the inner panel 101, and the outer panel 102 has a first protrusion 104 located within the wall thickness of the lower edge of the outer panel 102 and mating with the groove 103. The grooves 103 of a specific size are evenly distributed along the lower edge of the inner panel 101, while the first protrusions 104 are evenly distributed throughout the wall thickness of the lower edge of the outer panel 102. The first protrusions 104 are inserted into the grooves 103, resulting in a simpler, more effective, compact, and space-saving snap-fit structure.
[0023] The inner panel 101 further includes a plurality of first reinforcing plates 105, each of which is located above the groove 103. The first reinforcing plates 105 are disposed above the groove 103 and are integrally formed with the inner panel 101 to enhance the structural strength of the groove 103.
[0024] Secondly, the inner panel 101 also has a plurality of second reinforcing plates 106, each of which is horizontally distributed along the lower edge of the inner panel 101. The second reinforcing plates 106 are integrally formed with the inner panel 101 to enhance the structural strength of the lower edge of the inner panel 101.
