Referring to fig. 1-5, the present invention provides an automotive plastic part 200 with an anti-wear function, which includes a surface layer 210, a middle layer 220, a bottom layer 230, a molding layer 240 and a connecting structure 250;

the surface layer 210 is a scratch-resistant film attached to the middle layer 220, both the middle layer 220 and the bottom layer 230 are made of soft materials, and the bottom layer 230 is attached to the molding layer 240; the middle layer 220 is connected with the bottom layer 230 through a connecting structure 250, and the middle layer 220 has a contour corresponding to the side of the bottom layer 230 facing away from the molding layer 240; the molding layer 240 is integrally manufactured by an injection molding process, and the molding layer 240 is used for connecting with the interior of the automobile and has a shape adapted to the interior of the automobile;

the connecting structure 250 comprises a plurality of convex strips 251 convexly arranged on the middle layer 220, a plurality of grooves 252 formed on the surface of the bottom layer 230 away from the molding layer 240, a sliding groove 253 formed on the bottom surface of each groove 252, and a plurality of reinforcing ribs 254;

the plurality of reinforcing ribs 254 correspond to the plurality of sliding grooves 253 one by one, and each reinforcing rib 254 is slidably fitted along the extending direction of the corresponding sliding groove 253; the interval between the two side walls of each groove 252 along the extending direction thereof gradually increases from the opening to the bottom of the groove;

the end face, away from the middle layer 220, of each convex strip 251 is provided with a matching groove 255, and the convex strips 251 correspond to the grooves 252 one to one; along the extending direction of the groove 252, each matching groove 255 is used for matching with the reinforcing rib 254 in the corresponding groove 252, and two side walls of the matching groove 255 are unfolded outwards after being matched with the reinforcing rib 254 and are attached to two side walls of the groove 252, so that the protruding strip 251 and the groove 252 are clamped.

In this embodiment, since the automobile plastic part 200 with an anti-wear function needs to be assembled inside an automobile and used as an interior trim part of the automobile, when manufacturing the automobile plastic part 200 with an anti-wear function, the shape of the molding layer 240 needs to be adjusted according to the different decorated positions inside the automobile; because the molding layer 240 is manufactured by an injection molding process, and the bottom layer 230 and the middle layer 220 are both made of soft materials, the automobile plastic part 200 which is highly matched with the decorated position in the automobile and has an anti-abrasion function can be manufactured; when the bottom layer 230 and the middle layer 220 are arranged, because the bottom layer 230 and the middle layer 220 are connected through the connecting structure 250, and the connecting structure 250 needs to be matched with the matching groove 255 through the reinforcing rib 254 in the connecting process, the protruding strip 251 on the middle layer 220 deforms towards two sides so as to be attached to the side wall of the groove 252, so that the cross-sectional profile of the part, located at the bottom of the groove 252, of the protruding strip 251 is larger than that of the notch of the groove 252, that is, through the connecting mode, after the protruding strip 251 is matched with the reinforcing rib 254, the deformed structure and the groove 252 play a role in connection in a relative clamping mode, and further play a role in stable connection; when the ribs 254 slide out of the grooves 252, the engagement between the ribs 251 and the grooves 252 is lost, so that the engagement between the bottom layer 230 and the middle layer 220 is lost, and the middle layer 220 can be separated from the bottom layer 230, thereby facilitating maintenance or replacement of the surface layer 210.

Next, as can be seen from the above, when the engagement groove 255 is engaged with the rib 254, the engagement between the protrusion 251 and the groove 252 is lost, and thus, when the protrusion 251 is provided, the protrusion 251 may be made of a material having elasticity, so that the protrusion 251 can return to its original shape after being disengaged from the rib 254, thereby avoiding engagement with the groove 252.

In addition, referring to fig. 1 to 5, in the embodiment, the reinforcing ribs 254 are disposed to play a role in stabilizing and shaping the middle layer 220 and the bottom layer 230, so that the middle layer 220 and the bottom layer 230 are made of soft materials to improve the use experience, and the reinforcing ribs 254 improve the structural stability of the middle layer and the bottom layer, thereby prolonging the service life.

Further, it should be noted that, in this embodiment, when the surface layer 210, the middle layer 220, the bottom layer 230 and the molding layer 240 are disposed, the middle layer 220 and the bottom layer 230 are made of a soft material, and can absorb impact from the outside, so as to improve the use experience and protect the molding layer 240, while the surface layer 210 improves the wear resistance of the surface contacting with the user, so as to improve the service life, and the molding layer 240 performs a shaping function.

The working principle of the automobile plastic part 200 with the anti-abrasion function is as follows:
