Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts, more particularly to an automobile trim positioning pin. BACKGROUND

[0002] When installing the trim inside the car, the positioning pin on the trim is usually positioned first, and then the buckle on the trim is connected to the corresponding position inside the car. For example, the utility model patent with the publication number CN208069558U discloses a panel trim easy to position, which precisely installs the trim by setting multiple positioning pins on the trim.

[0003] For non-metallic trims, the positioning pin can be integrally formed by injection molding, but for some metal trims, the cost of integrally forming the positioning pin is high, so most of them are installed with positioning pins in the later stage. There are welding, threaded connection, etc., but welding is easy to cause deformation of the metal trim, and threaded connection sets a screw rod on the positioning pin and a threaded hole on the trim. However, the thickness of most positions on the trim is thin, and directly opening a threaded hole will cause unstable connection of the positioning pin. In order to improve the stability of threaded connection, only the specified position on the trim can be thickened, and then a threaded hole is opened. The thickened trim will affect its overall installation, and increase the process and cost. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides an automobile trim positioning pin which uses riveting, does not need welding, does not cause deformation of the trim, and has no threaded connection, good installation effect of the positioning pin, good firmness of installation, and low connection cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an automobile trim positioning pin, the positioning pin comprises a first riveting part, a second riveting part and a positioning part, and the first riveting part, the second riveting part and the positioning part are all cylindrical, the diameters of the first riveting part, the second riveting part and the positioning part decrease in turn, the outer circular surfaces of the first riveting part and the second riveting part are both riveting surfaces, and the riveting surface comprises a plurality of circumferentially distributed riveting protrusions.

[0006] Further, the axial section of the riveting protrusion is triangular or arc-shaped.

[0007] Further, the thicknesses of the first riveting part, the second riveting part and the positioning part in the axial direction decrease in turn.

[0008] Further, the stepped surface between the second riveting part and the positioning part is an inwardly recessed inclined surface with an inclination angle of 1-3 degrees.

[0009] Further, the first riveting part and the second riveting part are both provided with a chamfer.

[0010] Compared with the prior art, the beneficial effects of the utility model are that when connecting the positioning pin, first, the riveting holes corresponding to the first riveting part and the second riveting part of the positioning pin are formed on the mounting surface of the decorative strip, the first riveting part and the second riveting part are pressed into the corresponding riveting holes by using a riveting tool, until the side surface of the positioning part on the positioning pin abuts against the surface of the metal decorative strip, the installation of the positioning pin is completed, welding is not needed, the deformation of the decorative strip is not caused, there is no threaded connection, the positioning pin has good installation effect, good firmness of installation and low connection cost.
