Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the following further detailed description of the embodiments of the present application with reference to the drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The buckle provided by the utility model can be used for assembling various parts of an automobile, and the structure and the working principle of the buckle provided by the utility model are explained by taking the buckle for assembling the wheel arch as an example.
Referring to fig. 1 and 2, fig. 1 is a schematic structural view illustrating a wheel arch 200 fixedly mounted on a vehicle body sheet metal part 100 through a buckle 300, and fig. 2 is an exploded view of fig. 1.
This use neotype aim at provides a buckle 300 of novel structure to it is poor to overcome the spacing effect of traditional plastics standard part buckle, has fit-up gap's problem.
Referring to fig. 3 to 5, fig. 3 is a schematic view of a first orientation structure of the buckle 300; FIG. 4 is a schematic view of a second orientation structure of the buckle 300; fig. 5 is a schematic cross-sectional view of the buckle 300 engaged with the hole of the sheet metal frame 100.
The utility model discloses a buckle 300 for assembling automobile parts, wherein the buckle 300 and a wheel arch 200 are integrally cast. The buckle 300 includes a mounting seat 301, a positioning column 302 and a guiding head 303 integrally connected in sequence. The positioning post 302 has an intermediate groove 304 formed along its axial direction, and the intermediate groove 304 extends axially from one end of the positioning post 302 close to the mounting seat 301 to one end of the positioning post 302 close to the guide head 303 to divide the positioning post 302 into two halves along the axial direction. Elastic bolts 305 are respectively arranged at the bottoms of the two sides of the middle groove 304, one end of each elastic bolt 305 is fixed on the bottom of the middle groove 304, and the other end of each elastic bolt 305 extends to the upper part of the positioning column 302 along the height direction of the middle groove. Along the height direction of the middle groove 304, the outer axial surface of the elastic latch bolt 305 gradually expands outward, that is, the outer circumferential surface of the elastic latch bolt 305 is a reverse tapered surface with a smaller lower part and a larger upper part. The outer peripheral surface of the free end of the resilient latch bolt 305 is formed with an inwardly recessed step positioning portion 305a, and the step positioning portion 305a includes a step surface 305a1 in the radial direction and a raised surface 305a2 in the axial direction.
As shown in fig. 5, during assembly, the positioning post 302 of the buckle 300 is inserted into the clamping hole 101 of the sheet metal part, and the rising surface 305a2 of the resilient spring bolt step positioning portion 305a is abutted against the inner cylindrical surface of the clamping hole 101 of the sheet metal part, so as to realize radial position limitation of the wheel arch 200 and the sheet metal part 100; the step surface 305a1 of the step positioning portion 305a is just attached to the inner wall of the sheet metal part at the periphery of the clamping hole 101 (see fig. 1) so as to realize the axial limit of the wheel arch 200 and the sheet metal part 100.
It can be easily understood that, when the two elastic lock tongues 305 deform and move inward when being pressed radially inward, the raised surfaces 305a2 of the step positioning portions 305a can be firmly abutted in the clamping holes of the sheet metal part under the action of the elastic force of the elastic lock tongues 305, so that the wheel arch 200 can be reliably limited in the radial direction. In addition, the step surface 305a1 of the step positioning portion is designed to be matched with the shape of the inner wall of the sheet metal part around the clamping hole 101, and after the assembly is completed, the step surface 305a1 can be tightly attached to the inner wall of the sheet metal part 100 around the clamping hole 101 (the assembly gap is reduced), so that the wheel arch 200 is reliably limited in the axial direction.
Further, the rising surface 305a2 is a flat surface, and the step surface 305a1 is a slant plane or a slant arc surface.
Further, a reinforcing rib plate 301a is arranged between the mounting seat 301 and the wheel arch 200.
In conclusion, the structure optimization design is carried out on the buckle, the firm assembly of the wheel arch and the sheet metal part is realized, and the problems that the limiting effect is poor, the wheel arch is not attached to the sheet metal part and is easy to loosen due to the adoption of the traditional buckle are solved.
