Description

Combined buckle

Technical Field

The invention relates to the technical field of automobile parts, in particular to a combined buckle.

Background

When the automobile runs under a complex road condition, the probability that parts in the wheel cavity are damaged by silt, broken stones and the like is high, and the requirement of the protection function of the parts (such as an oil pipe, a wire harness, a generator and the like) in the wheel cavity cannot be met. In order to meet the protection requirements of parts in a wheel cavity, a splash guard is often required to be arranged on a fender of an automobile.

In the first prior art (as shown in fig. 1), a splash guard 4 'is fixed to a fender panel 3' by using a plastic clip 1 'and a tapping screw 2'. The method specifically comprises the following steps: 1) sleeving the plastic clamping piece 1 ' on the splash guard 4 ', and ensuring that the clamping piece does not fall off by using the side wall and the circular boss above the plastic clamping piece 1 '; 2) sleeving a splash guard 4 ' with a clamping piece on the fender 3 ' by using the side wall below the plastic clamping piece 1 ', so that the splash guard 4 ' is positioned at the inner side of the fender 3 ', and is aligned with the hole positions on the plastic clamping piece 1 ' and the fender 3 '; 3) the fender 3 ', the splash guard 4' and the plastic clamping piece 1 'are firmly fixed by the self-tapping screw 2'. The disadvantages of this fixing method are: 1) the plastic clamping piece 1 ' is exposed below the fender 3 ', the clamping piece 1 ' is large in size and convenient to mount, the edge below the clamping piece 1 ' is provided with a raised flanging, and the clamping piece 1 ' can be obviously observed on the outer side of a vehicle body to influence the appearance quality of the whole vehicle; 2) the self-tapping screw 2 'is used for fixing, and the cross groove at the top of the screw 2' is easy to corrode.

In the second prior art (as shown in fig. 2), a snap fastener 5 ' is used to fix a splash guard 4 ' to a fender 3 '. The method specifically comprises the following steps: 1) lapping the splash guard 4 'on the outer side of the fender 3', and aligning the splash guard 4 'with the hole position on the fender 3'; 2) the splash guard 4 ' and the fender 3 ' are firmly fixed by the expansion action of the snap fastener 5 '. The disadvantages of this fixing method are: the edge of the splash guard 4 ' is exposed due to the installation mode, and the splash guard 4 ' and the fender 3 ' are not attached to each other on the matching surface due to the interval distribution of the fixing points, so that the appearance quality is influenced.

In the third prior art (as shown in fig. 3), the splash shield 4' is fixed to the vehicle body by using a plastic buckle or a fastener. The method specifically comprises the following steps: 1) putting the boundary of the splash guard 4 'into the fender 3'; 2) aligning the hole position on the splash guard 4' with the hole position of the car body; 3) the splash shield 4' is fixed on the vehicle body by plastic buttons or fasteners. The disadvantages of this fixing method are: 1) the fixed point is above the tire, so that the observation is difficult and the operation is inconvenient; 2) the structure of the fixing point of the splash guard 4' is complex, and a hole position or a bracket is required to be added at the fixing point of the car body, so that the overall cost is increased; 3) the edge of the splash guard 4 'is not fixed with the fender 3', and the stability is poor.

Therefore, it is highly desirable to provide a new combination buckle to solve the above problems.
