Description

Door guard armrest frame

technical field

The utility model relates to the technical field of automobile parts, in particular to an automobile door guard plate handrail skeleton.

Background technique

Generally, the relevant structure of the armrest area of the door guard includes an integrally formed plastic armrest frame and a soft skin covering the surface. The armrest also needs to be equipped with a switch. The ideal shape of the armrest frame a, the switch panel b and the soft skin c As shown in Figures 1 and 2, it is necessary to open a long hole a1 in the middle of the armrest frame a for assembling the switch and set a circle of sunken supporting structure a2 around it to cooperate with the switch panel b. When manufacturing the handrail frame a, the mold is released along the direction marked in the figure, and the area B inside the long hole a1 on the handrail frame a is generally shaped with the help of the inclined roof below. When the map pocket located at the lower part of the door guard is close to the armrest, considering the overall connection of each part, the inner side of the armrest frame a needs to be bent to the outer side and the lower side of the door to a greater extent in shaping, respectively. In this way, it is very easy to block the inclined roof after bending, so that the part cannot be released from the mold. At this time, it is no longer possible to shape the area B through the inclined roof. Therefore, it is necessary to adjust the local structure of the handrail skeleton on the premise of maintaining the basic shape, so as to reduce the overall processing difficulty of the parts.

Contents of the invention

In order to solve the problems in the prior art, the utility model designs an easy-to-shape car door guard armrest skeleton.

The armrest skeleton of the car door guard plate in the utility model includes a main panel and a side panel located below the main panel. There is a switch assembly hole, and a sunken support structure is set on the edge of the switch assembly hole. The special feature is that the main panel between the support structure and the side panel is a thickened wedge-shaped transition body. A set of weight-reducing blind holes is evenly opened on the top surface of the wedge-shaped transition body. The edge of the bottom surface of the wedge-shaped transition body transitions with the bottom surface of the supporting structure with a smooth transition surface, which is surrounded by the bottom surface of the supporting structure, smooth transition surface, wedge-shaped transition body bottom surface and side panels. The height of the half-enclosed inner cavity formed by the stopper gradually narrows toward the inner side of the car door.

The weight-reducing blind hole is arranged perpendicular to the bottom surface of the wedge-shaped transition body, and the distance between the bottom surface of the weight-reducing blind hole and the bottom surface of the wedge-shaped transition body is consistent with the material thickness of the supporting structure.

The armrest framework of the door guard plate of the utility model has a simple structure, is easy to process and manufacture, and has low production cost.

detailed description

Below in conjunction with the accompanying drawings and specific embodiments, the armrest frame of the door guard plate of the present invention will be further described.

As shown in Figures 3 to 5, the armrest frame of the inner door panel of the utility model includes a main panel 1 and a side panel 2 located below the main panel 1. There is a fusion connection at the main panel 1. There is a switch assembly hole 11 along the length direction on the main panel 1, and a sunken support structure 12 is provided on the edge of the switch assembly hole 11. The special feature is that it is between the support structure 12 and the side panel. The main panel 1 between the 2 is a thickened wedge-shaped transition body 13, a group of weight-reducing blind holes 14 are evenly opened on the top surface of the wedge-shaped transition body 13, and a smooth transition surface 15 is connected to the supporting structure at the edge of the bottom surface 131 of the wedge-shaped transition body. The bottom surface 121 transitions, and the height of the semi-enclosed inner cavity formed by the supporting structure bottom surface 121, the smooth transition surface 15, the wedge-shaped transition body bottom surface 131 and the side panel 2 enclosure gradually narrows toward the inside of the door.

The armrest frame of the door guard panel partially fills the difficult-to-shape area B in Figure 1, and is designed as a thickened wedge-shaped transition body 13, which greatly reduces the difficulty of local shaping while keeping the basic shape of the armrest frame unchanged. . At the same time, setting the weight-reducing blind hole 14 can reduce the weight of parts, save materials, and reduce production costs.

The semi-enclosed inner cavity formed by the bottom surface 121 of the supporting structure, the smooth transition surface 15, the bottom surface 131 of the wedge-shaped transition body and the enclosure of the side panels 2 can be shaped by a common mold, and it is easy to remove the mold. The weight-reducing blind hole 14 can be designed The sloping roof molding on the front of the armrest frame is less prone to defects such as air bubbles, blow-through, sink marks, and too thin or too thick walls, compared with similar products that are partially molded by special processes, and the yield rate is high. Therefore, this The armrest frame of the car door guard plate described in the utility model is easier to process and manufacture, and has lower production cost.

The weight-reducing blind hole 14 is arranged perpendicular to the bottom surface of the wedge-shaped transition body 13 , and the distance between the bottom surface 141 of the weight-reducing blind hole and the bottom surface 131 of the wedge-shaped transition body is consistent with the material thickness of the supporting structure 12 .

As shown in Figure 6, the armrest part of the car door guard includes an armrest frame, a soft cover skin 3 and a switch panel 4, and the soft cover skin 3 covers the surface of the main panel 1 and the side panel 2 of the armrest frame, and blocks the weight-reducing blind hole 14 , so the weight-reducing blind hole 14 will not affect the overall appearance of the handrail. The switch panel 4 cooperates with the supporting structure 12 and is embedded in the switch assembly hole 11 .
