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 11 As shown, limited by the installation position, it is often necessary to weld the nut 7 on one of the sheet metal parts. The nut 7 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

Embodiment Construction
[0028] Below by embodiment, in conjunction with accompanying drawing, the present invention is described in further detail:
[0029] like figure 1 The connecting fastening structure of the sheet metal parts shown is composed of the first sheet metal part 5, the second sheet metal part 6 and the fastening connection assembly. The fastening connection assembly consists of a connecting rod 1, a return spring 2, and a limit pin Composed of 3 and 4 flat pads.
[0030] like figure 2 As shown, the connecting rod 1 has an end 1a, the return spring 2 and the flat pad 4 are sequentially set on the connecting rod 1, and a pin through hole 1b is arranged at the lower end of the rod part of the connecting rod 1, and the limit pin 3 is inserted in the pin passing through hole 1b. In the hole 1b and fixedly connected with the connecting rod 1. The return spring 2 and the flat washer 4 are located between the end 1a of the connecting rod 1 and the pin through hole 1b. The axis of the pi...

The invention discloses a stamping part connecting fastening structure which comprises a first stamping part (5), a second stamping part (6) and a fastening connecting assembly. The fastening connecting assembly is composed of a connecting rod (1) with an end (1a), a return spring (2), a limiting pin (3) and a plain cushion (4). The lower portion of the connecting rod (1) and the limiting pin (3) rotate for a certain angle after penetrating through a via hole (5c) on the first stamping part (5) and a combination hole (6c) on the second stamping part (6), until two ends of the limiting pin (3) are respectively stopped through one of limiting protrusions (6d) so as to limit the continued rotation position of the limiting pin (3). The stamping part connecting fastening structure has the advantages that the stamping part connecting fastening structure is low in manufacturing cost, is assembled and disassembled without using a tool and is convenient and efficient and firm and reliable to connect, and secondary loading and unloading are unaffected completely, and the like.
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 10 As shown, bolt through holes are respectively set on the two sheet metal parts, and the bolt 8 passes through the two sheet metal parts and then combined with the nut 7 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 11 As shown, limited by the installation position, it is often necessary to weld the nut 7 on one of the sheet metal parts. The nut 7 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 pneu...
