RU220265U1 - DESIGN OF A PASSENGER CAR DOOR TRIM - Google Patents

Abstract

The utility model relates to the field of transport engineering, namely to the designs of car door upholstery, in particular a passenger car.

The technical result of the utility model is aimed at increasing the reliability of fixing the window sill to the door trim body, due to the precise positioning of the mating parts using non-specific elements using the welding method.

A car interior door trim structure containing a door trim body 1, a window sill 2 located along the lower edge of the window opening of the door panel, configured to be rigidly connected to each other by fastening and fixing elements, structurally designed in the form of bosses 5, mating holes 4 and welded pads 7. The bosses 5, formed on the inner surface 8 of the window sill 2, mate with the matching holes 4, formed along the surface of the window sill beam 3 of the door trim body 1, equidistant to the location and number of bosses of the mating surface. Welded areas 7, formed on the bent flange 6 along the upper edge of the upholstery body 1, are rigidly connected to the welded areas 7 of the window sill 2 by welding, forming a monolithic structure. 6 ill.

Description

The utility model relates to the field of transport engineering, namely to the designs of car door upholstery, in particular a passenger car.

A search of patent documentation did not reveal technical solutions similar to the claimed solution.

The technical result of the utility model is aimed at increasing the reliability of fixing the window sill to the door trim body, due to the precise positioning of the mating parts using non-specific elements using the welding method.

The stated technical result is achieved by the fact that the car interior door trim structure, which contains a door trim body, a window sill plate located along the lower edge of the window opening of the door panel, is configured to be rigidly connected to each other. The fastening and fixing elements are structurally made in the form of bosses, counter holes and welded areas. The bosses formed on the inner surface of the window sill lining mate with the counter holes formed along the surface of the window sill beam of the door trim body, equidistant to the location and number of bosses of the mating surface. Welded areas formed on a bent flange along the upper edge of the upholstery body are rigidly connected to the welded areas of the window sill by welding, forming a monolithic structure.

A comparison of the claimed technical solution with the level of technology according to scientific, technical and patent documentation at the priority date in the main and related categories shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition - “novelty”.

The proposed technical solution is industrially applicable, because can be industrially manufactured, workable, feasible, reproducible, and therefore meets the patentability requirement of “industrial applicability.”

The essence of the technical solution is shown in the drawings:

Fig. 2 - fragment of door trim in the area of the window sill;

The design of the passenger car door upholstery includes structurally separate parts, such as: upholstery body 1, window sill 2 rigidly connected to each other. The body of the upholstery 1 of the passenger car interior door is a shaped surface of a volumetric-spatial shape with a complex figured silhouette of a closed profile, repeating the contours of the relief of the interior panel of the passenger car interior door. In the surface of the window sill beam 3 of the body 1 there are through counter holes 4, the number and location of which is equidistant to the location and number of bosses 5 of the window sill cover 2. In the surface of the bent flange 6 along the upper edge of the body 1, welded areas 7 are formed.

Window sill 2, located in the window sill area of the window opening of the inner panel of the car body door and representing an overlay part made by injection molding from polypropylene. Along the lower edge, on the inner side 8 of the window sill 2, mating with the window sill beam 3 of the body 1, bosses 5 are formed. On the inner surface of the lining 2, welded areas 7 are formed.

In the process of assembling the door trim, the window sill 2 comes into contact with the body of the upholstery 1, is positioned using bosses, with preliminary fixation with latches 9 along the upper edge of the bent flange 6 of the door trim and the mating part 8 of the window sill, after which the final fixation occurs by welding (thermal precipitation ) 10. Thus, individual structural elements, such as the upholstery body 1 and the window sill 2 form a monolithic structure, making the inventive structure more rigid and integral.

Claims (1)

A car interior door trim structure containing a door trim body, a window sill located along the lower edge of the window opening of the door panel, configured to be rigidly connected to each other by fastening and fixing elements, structurally made in the form of bosses, counter holes and welded areas, wherein the bosses , formed on the inner surface of the window sill, mate with mating holes formed along the surface of the sill beam of the door trim body, equidistant to the location and number of bosses of the mating surface, and welded areas formed on a bent flange along the upper edge of the upholstery body are rigidly connected to the welded areas of the window sill linings are welded, forming a monolithic structure.
