Embodiment 1

[0053] Figure 4 A flow chart of a fender processing method provided by an embodiment of the present application; Figure 5(a)-Figure 5(d) A simplified structural diagram corresponding to each step in the fender panel processing method provided by an embodiment of the present application.

[0054] See Figure 4 , Fig. 5(a), the fender processing method provided by this embodiment can start from step S100, stamping on the fender 200 once to obtain the main part 211 and the corner part 212 of the bright strip groove 210, and the corner part 212 The distance to the notch of the bright stripe groove 210 is smaller than the distance from the main body 211 to the notch of the bright stripe groove 210 . Wherein, the corner portion 212 is an area close to two adjacent groove walls in the bright stripe groove 210 , and the length of the corner portion 212 accounts for 20-30% of the entire length of the bright stripe groove 210 .

[0055] Specifically, as shown in FIG. 5( a ), an ope...

Embodiment 2

[0076] Figure 9 A schematic structural diagram of a fender assembly provided by an embodiment of the present application. See Figure 9 , this embodiment provides a fender assembly, including a fender 200 and a bright strip 300, wherein the fender 200 is processed by the fender processing method in the first embodiment above, and the bright strip 300 is installed in the bright strip groove Inside.

[0077]In an optional embodiment, multiple installation holes are provided in the bright strip groove of this embodiment, and the side of the bright strip 300 facing the bright strip groove is provided with multiple fixing holes, multiple installation holes and multiple fixing holes In one-to-one correspondence, the fasteners pass through the mounting holes and are fixed in the fixing holes; in this embodiment, the mounting holes may be, for example, through holes, the fixing holes may be, for example, threaded holes, and the fasteners may be, for example, screws. After the brig...

Embodiment 3

[0081] This embodiment provides an automobile, including a chassis and a vehicle body. The fender assembly as described in the second embodiment above is provided on the vehicle body, and the fender assembly is arranged on two side walls in the width direction of the vehicle body.

[0082] Specifically, the fender assembly of this embodiment is arranged on the vehicle body adjacent to the tires to cover the tires. Generally, it includes two front fenders used to cover the front wheels and two front fenders used to cover the rear wheels. wheel rear fender.

[0083] Since the automobile provided in this embodiment adopts the fender assembly of the second embodiment above, it is not easy to leave corrugated defects on the surface of the fender around the bright strip groove, which is conducive to maintaining the flatness of the surface of the fender , to enhance the overall appearance of the fender.

Abstract

The invention provides a fender machining method, a fender assembly and an automobile. The fender machining method comprises the steps that one-time stamping is conducted on a fender, a main body part and a corner part of a bright strip groove are obtained, the corner part is the area, close to two adjacent groove walls, in the bright strip groove, the length of the corner part accounts for 20-30% of the length of the whole bright strip groove, and the distance from the corner part to a notch of the bright strip groove is smaller than that from the main body part to the notch of the bright strip groove; a process hole is processed in the corner part; and the corner part is subjected to secondary stamping, so that the distance from the corner part to the notch of the bright strip groove is equal to the distance from the main body part to the notch of the bright strip groove. According to the fender machining method, corrugated defects are not prone to being generated on a fender on the periphery of the corner part of the bright strip groove, the smoothness of the surface of the fender can be kept, and the overall appearance of the fender is improved.

Description

technical field [0001] The application relates to the manufacturing technology of auto parts, in particular to a fender processing method, a fender assembly and an automobile. Background technique [0002] The fender is the outer panel of the car body that covers the wheels. It is named after the shape and position of the part on the old car body like a bird's wing. According to the installation position, the fenders can be divided into front fenders and rear fenders. When the car is running, the fenders can prevent the sand, gravel and mud rolled up by the wheels from splashing to the bottom of the car. [0003] With the improvement of people's consumption level, users have higher and higher requirements for the aesthetics of the automobile body. In order to improve the aesthetics of the fender part of the vehicle body, in the scheme of the related art, bright strips are usually added on the fender. figure 1 It is a simplified structural diagram of the fender in the relat...
