Mounting structure for automobile trunk shelves

Abstract

The invention discloses a mounting structure for automobile trunk shelves, which comprises a side trim panel, a shelf and a mounting part, the shelf is connected with the side trim panel through a rotary shaft, the side trim panel is provided with a bent part, the rotary shaft is integrally arranged on a vertical section, and the vertical section is also provided with welding holes; welding posts are arranged on the inner side of the bent part of the side trim panel, and the bent part of the side trim panel is provided with a through pin hole; the mounting part is located at the inner side of the side trim panel, a pin runs through the through pin hole, the welding posts are located in the welding holes and welded as a whole, the vertical section of the mounting part is in contact with the inner side of the bent part of the side trim panel, and a horizontal section of the mounting part is in contact with the inner side of the side trim panel. The mounting structure can enhance the carrying capability of the rotary shaft, so that the head of the rotary shaft can be prevented from breaking.

Description

technical field [0001] The invention relates to an installation structure of auto parts, more specifically to an installation structure of a storage board of an automobile trunk. Background technique [0002] Hatchback and SUV models generally place a shelf or curtain in the trunk area. Because the shelf has better support, it can hold more items and is more configured in the car. The existing shelf generally has a flipping function. When the back door of the car is opened, the drawstring pulls the shelf up to a certain angle with the opening of the back door, which is convenient for the user to take and place items in the trunk. A matching rotating structure is designed on the interior trim panel of the trunk side of the car. [0003] There are two kinds of installation structures for the existing shelf board, one is to design the rotating shaft on the shelf board, and design the rotating hole on the interior trim panel; the other is to design the rotating hole on the shel...

AI Technical Summary

Problems solved by technology

The first structure is rarely used because the fixed rotating shaft on the shelf is not firm, and it is easy to damage the rotating shaft when the shelf is disassembled.

Existing models generally adopt the second type of structure, the shaft and the interior trim are made into one piece, and the integral injection molding is adopted. Although this structure has a simple process and a good overall appearance, it also has major defects, such as the shaft is easy to break or damaged

Because the interior panels of automobile side panels are generally injection-molded with polypropylene material, the material has low strength and poor wear resistance, and cannot withstand the frequent rotational friction of the shelf, especially when the items placed on the shelf are too heavy, it is very difficult to The rotating shaft may be deformed or broken. Once the rotating shaft is damaged, the entire interior panel must be replaced, which is costly, time-consuming and laborious
