Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a stable fastener for installing automobile interior decoration. Background Art

[0002] Interior assembly is a key step in the automotive manufacturing process. Interior components include door trims, seats, instrument panels, steering wheels, center consoles, etc. Due to the complex structure, diverse materials, and different molding methods of automotive interior components, there are many types of installation methods and many types of fasteners required. Commonly used interior fasteners include C-type clips, B-type clips, plastic cotter pins, plastic embedded nuts, elastic clips, reed nuts, etc.

[0003] Generally speaking, most automotive interior fasteners are used to connect sheet metal and plastic parts. However, due to the different cushioning properties of sheet metal and plastic parts, using only metal fasteners or plastic fasteners for connection will affect the stability of the connection due to material reasons.

[0004] The existing public technical solution, announcement number CN215596092U discloses a stable fastener for automobile interior installation, including a nut assembly and a bolt assembly; the nut assembly includes a connecting plate, a clamping plate and a connecting nut, the connecting nut is arranged between the connecting plate and the clamping plate, and the connecting plate and one side of the clamping plate are connected, and the clamping plate is provided with a clamping spring piece on the side facing the connecting plate, and the clamping spring piece is provided with a clamping claw, and the clamping claw extends toward the direction of the connecting plate; a buffer pad is provided on the side of the connecting plate away from the clamping plate; the clamping claw is embedded in the clamping groove, and the clamping spring piece abuts against the inner wall of the clamping groove, thereby firmly connecting the clamping plate and the connecting plate to the plastic part, and then the bolt assembly can be used to stably and firmly lock the plastic part and the metal frame together.

[0005] When the above technical solution is actually implemented, the clamping spring is used to clamp the plastic part, and then the clamping spring and the metal frame are fixed by bolts. The screw component of the bolt needs to pass through the connecting nut installed on the metal frame and then fixed on the clamping spring. At this time, the connecting nut needs to be clamped into the plastic part. During the connection process, the holes must be accurate. Once the position of the opening on the metal frame does not match the position of the connecting nut, the connection will fail and secondary punching will be required. However, multiple punching of the metal frame will reduce its own strength. Summary of the Invention
