Assembly structure of sheet metal parts for vehicles

Abstract

The invention discloses a sheet metal component assembling structure for a vehicle. The sheet metal component assembling structure comprises a first sheet metal component (5), a second sheet metal component (6), a fastening connection component and a locating plate (7), wherein the fastening connection component consists of a connection rod (1) with an end socket (1a), a return spring (2), a limiting pin (3) and a flat cushion (4); after the lower part of the connection rod (1) and the limiting pin (3) pass through a first profile hole (5c) in the first sheet metal component (5), the lower part of the connection rod (1) and the limiting pin (3) are rotated for a certain angle along anti-clockwise direction, then pass through a third round hole (6a) in the second sheet metal component and a second profile hole (7c) of the locating plate (7), and are rotated for a certain angle along clockwise direction until the two ends of the limiting pin (3) respectively fall into two locking tanks (7f). The structure has the characteristics that the manufacturing cost is low, the dismounting does not need tools and is convenient and quick, the connection is firm and reliable, and the secondary mounting and dismounting are completely not affected.

Description

technical field [0001] The invention relates to a sheet metal part for a vehicle, in particular to an assembly structure of a sheet metal part for a vehicle. Background technique [0002] There are a large number of sheet metal parts on motorcycles and automobiles. At present, the connection of such parts is usually connected by bolt and nut components, such as Figure 9 As shown, bolt through holes are respectively set on the two sheet metal parts, and the bolts 8 pass through the two sheet metal parts and then combined with the nuts 9 to fasten the two sheet metal parts together. The main problems that exist are: (1) after the bolts and nuts are disassembled, the nuts are easy to fall off: (2) if Figure 10 As shown, limited by the installation position, it is often necessary to weld the nut 9 on one of the sheet metal parts. The nut 9 is a projection welding nut, which increases the assembly process; (3) When the bolt is fastened, it is often used with the help of a pneum...

Problems solved by technology

The main problems that exist are: (1) after the bolts and nuts are disassembled, the nuts are easy to fall off: (2) if Figure 10 As shown, limited by the installation position, it is often necessary to weld the nut 9 on one of the sheet metal parts. The nut 9 is a projection welding nut, which increases the assembly process; (3) When the bolt is fastened, it is often used with the help of a pneumatic or electric sleeve Due to the large torque of the power tool, the bolts often have forced tightening phenomena such as tooth extraction and threading, which brings great inconvenience to the secondary maintenance; (4) For optional parts such as shelves and side boxes that are often disassembled, The user needs to disassemble frequently, and the user generally uses a bayonet wrench, which is easy to wear the edge of the hexagonal head, resulting in difficulty in disassembly and even damage
