Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumpers, in particular to a decorative bumper with imitation carbon fiber stripes. Background Art

[0002] The front bumper refers to the horizontal beam between the two fog lights under the grille. Bumpers are installed at the front and rear ends of the car. They not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact, protect the body and protect the body and occupants. Previously, the front and rear bumpers of cars were mainly made of metal materials, which were stamped into U-shaped channel steel with a thickness of more than 3 mm, chrome-plated on the surface, and riveted or welded to the frame longitudinal beams. Today's front and rear bumpers of cars are made of plastic, called plastic bumpers. Generally, the plastic bumper of a car is composed of three parts: outer panel, buffer material and cross beam, of which the outer panel and buffer material are made of plastic. The crossbeam is stamped into a U-shaped groove with cold-rolled thin plates, and the outer plate and buffer material are attached to the crossbeam. Carbon fiber is a high-strength, high-modulus, lightweight material with excellent mechanical properties and chemical stability. It is widely used in automobiles, aerospace, sports equipment and other fields. The characteristic of carbon fiber material is that fibers woven at different angles are interwoven into a mesh structure to form a fabric. There are two basic weaving methods in the carbon fiber fabric, namely plain weave and twill. Twill has better strength and toughness than plain weave, but plain weave has more rigidity and directional stability than twill. The difference between twill and plain weave lies in the way and angle of fiber weaving. Plain weave fiber Crossed at an angle of 90 degrees, the fibers present a serial interlaced form, forming continuous straight stripes, presenting a smooth, bright, and soft surface, which is suitable for making products that require strength and rigidity, while twill fibers are woven at a certain angle, and its angle is generally 45 degrees. The fibers intersect at this angle, and the fibers form oblique lines and stripes, presenting a special-shaped interlaced surface, which is suitable for preparing products with high toughness and elasticity. Since twill is more resilient than plain weave, twill woven carbon fiber is more suitable for occasions that resist impact and vibration, such as making sports equipment and aviation equipment, and some other occasions. Plain carbon fiber is needed, such as for making auto parts, smart phone casings, bathroom equipment, etc. The carbon fiber used in automobiles is usually to ensure the strength of the car body while reducing the weight of the car body. However, due to the high price of carbon fiber, in order to reduce costs, some vehicles' bumpers are installed and used with imitation carbon fiber stripe decorative panels instead of carbon fiber panels. However, due to the different materials between the imitation carbon fiber stripe decorative panels and the bumper outer panels, they need to be fastened with bolts during installation. The bolts located at the front of the vehicle are easily loosened due to long-term vibration of the vehicle, which may cause the imitation carbon fiber stripe decorative panels to fall off.
