Problems solved by technology

[0003] Most of the front and rear bumpers of existing cars are made of metal or plastic materials, which have poor shock absorption and buffering capabilities. After a collision, the impact force is concentrated, making the bumper easily deformed or broken, and weakening the protective function of the bumper.

Embodiment Construction

[0010] Example figure 1 Shown, the automobile bumper that the present invention improves impact resistance comprises bumper body 1, waterproof plug 2 and non-Newtonian fluid, and described bumper body 1 is provided with hard mold cavity, and described hard mold cavity is in bumper An opening 11 is provided on the top surface of the body 1, the non-Newtonian fluid is poured into the hard cavity, and the waterproof plug 2 is arranged at the opening 11 of the hard cavity.

[0011] Preferably, the non-Newtonian fluid is a concentrated polymer solution or cornstarch solution.

[0012] Non-Newtonian fluids refer to fluids that do not satisfy Newton's viscosity experimental law, that is, fluids that have a non-linear relationship between shear stress and shear strain rate, such as petroleum, mud, coal water slurry, ceramic slurry, paper pulp, paint, ink, Toothpaste, silk regeneration solution, etc. are all non-Newtonian fluids. Applying an impact force to a non-Newtonian fluid, a s...

Abstract

The invention discloses a Car bumper for improving impact resistance. The bumper comprises a bumper body, a waterproof plug and a non-Newtonian fluid. The bumper body is provided with a rigid mold cavity, the rigid mold cavity is provided with an opening on the top surface of the bumper body, the non-Newtonian fluid is poured into the rigid mold cavity, and the waterproof plug is arranged at the opening of the rigid mold cavity. The bumper overcomes the defects of the traditional metal or plastic material bumper, remarkably improves the vibration absorption and cushioning capacity after collision, scatters the impact force after collision, thereby decomposing and transmitting the impact force to other positions, and effectively improves the protective function of the bumper.

Description

technical field [0001] The invention relates to an automobile bumper with improved impact resistance. Background technique [0002] Usually, the front and rear ends of the car are equipped with bumpers. The bumper not only has a decorative function, but also absorbs and eases the impact of the outside world to protect the safety of the vehicle body and passengers. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road of innovation. At present, in addition to maintaining the original protective function, the front and rear bumpers of automobiles also need to pursue harmony and unity with the shape of the car body, and pursue their own lightweight. The geometric shape of the bumper should not only consider its consistency with the shape of the vehicle to ensure aesthetics, but also conform to the mechanical characteristics and ene...
