The Mazda front bumper spring has a cushioning function, and its cushioning is realized by a spring, that is, a buffering function is realized by means of springs of two different degrees of coefficient. The simple working mechanism is: the sensitivity of the spring according to the two stiffness coefficients is different. The current baffle is less affected by the impact. If it hits a pedestrian, the small spring is quickly compressed and effectively buffered. The damage is minimized, but the large spring response is small.
When the collision force is large, the small spring plays a small role, and the large spring of the Mazda front bumper spring is compressed to effectively buffer the passenger damage in the vehicle to a minimum.
It can be seen from the above that the front bumper spring for Mazda composed of two kinds of springs with two different degrees of coefficient is mainly composed of a main body front baffle and a buffer mechanism of the bumper. The front baffle is measured by the effect of the telescopic movement of the entire mechanism, and materials with light weight and high strength should be selected. The innovative part of the entire bumper mechanism lies in the buffer mechanism, which has two sets of symmetrical components.
