Automotive radiator grille decorating electroplated bright strip assembling structure

Abstract

The invention belongs to the technical field of automobile accessories and provides an automotive radiator grille decorating electroplated bright strip assembling structure which comprises a bright strip body and a grille body. Multiple self-tapping screw mounting columns and two clamping claws are arranged on an inner-side mounting face of the bright strip body, locking pieces matched with the self-tapping screw mounting columns and inserting grooves matched with the clamping claws are arranged on the grille body respectively, each inserting groove is composed of an inserting portion and extending connection portions on two sides, the clamping claws and the bright strip body form a whole through the extending connection portions, inserting direction of each inserting portion is uniform with transverse direction of the corresponding inserting groove, and a thickening portion is arranged at a junction between each inserting portion and the corresponding extending connection portion and is of a non-sharp-angled structure. The automotive radiator grille decorating electroplated bright strip assembling structure has the advantages that under the premise that performance is guaranteed, appearance performance of an automotive radiator grille decorating strip is guaranteed, rejection rate of injection molding and electroplating processes is greatly reduced, die processing technique is improved, die service life is prolonged, and wind dryness after the automotive radiator grille decorating electroplated bright strip assembling structure is mounted on an automobile is prevented.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an assembly structure of an automotive radiator grille decorative electroplating bright strip. Background technique [0002] In the design of the appearance of plastic parts, such as the radiator grille decoration electroplating bright strips, because it is an ABS resin product of electroplating injection molding parts, it is necessary to comprehensively consider the molding of the product structure, whether there is any undercut in the structure of the product, Whether there is enough space in the assembly structure of the product for the removal of the slider or the inclined roof. The following results will be caused during the design and production process of the existing automotive radiator grille decorative electroplating bright strips: 1. The installation direction of the electroplating decorative strips is inconsistent with the X direction of the vehicle body (the install...

AI Technical Summary

Problems solved by technology

The following results will be caused during the design and production process of the existing automotive radiator grille decorative electroplating bright strips: 1. The installation direction of the electroplating decorative strips is inconsistent with the X direction of the vehicle body (the installation direction of the decorative strips), and forms a certain angle. During installation, it is easy to flip along the Z direction of the car body, thereby scratching the flange of the grille body, or causing poor assembly; Insufficient strength; 3. The corresponding self-tapping screw base mounting column of the automobile radiator grille body is a flat structure. When the self-tapping screw is installed, there will be corresponding waste exiting along the inner wall of the hole, and there is no corresponding space for the structure modification; 4. Design There is no positioning insert at the time, and the bright strip of the radiator grille for automobiles is positioned by the one-piece claw and the corresponding screw column. Because the one-piece claw structure and the self-tapping screw are elastically positioned, there will be a certain offset and rotation during installation. It is easy to cause inaccurate positioning, which affects the assembly accuracy and fit clearance of the product; 5. There is no gap on both sides of the bright strip of the radiator grille for automobiles, and it is difficult to align the mold core and cavity at the parting line; There is no corresponding reinforcing rib for the mounting column of the tapping screw. When the assembly is assembled, the self-tapping screw is mechanically installed, and the torque is relatively large. The mounting column of the self-tapping screw is easy to break or burst due to insufficient strength; The wall thickness of the corresponding structural connection between the bar and the body is too thick, and the surface of the product is prone to shrinkage and deformation after injection molding because the local wall thickness is too thick, and the commercial performance of the product’s surface appearance cannot be guaranteed; 8. The body of the radiator grille for automobiles has no corresponding flange The structure is covered with bright strips, and customers can see the gap between the grille body and the decorative strips or the product boundaries are not uniform (due to processing errors and craftsmanship), and the appearance and commercial performance of the vehicle cannot be guaranteed
