Automotive automatic repair, buffering and energy absorption device

Abstract

The invention provides an automotive automatic repair, buffering and energy absorption device and belongs to the technical field of automobile parts. Two energy absorption boxes are fixedly connected between a fixing frame and a beam, wherein each energy absorption box is fixedly connected with a piezoelectric thin film; the fixing frame is fixedly connected with an overflow valve and a liquid tank; two ends of an energy absorption box flow inlet pipe are communicated with the front portions of the upper sides of the two energy absorption boxes respectively; the right portion of the energy absorption box flow inlet pipe is communicated with the back side of the overflow valve through an overflow valve flow outlet pipe; two ends of an energy absorption box flow outlet pipe are communicated with the rear portions of the lower sides of the two energy absorption boxes respectively; the energy absorption box flow outlet pipe and a liquid tank front side hole are communicated with two ends of a flow return pipe respectively; the middle of the flow return pipe is communicated with the right side of the overflow valve through an overflow pipe; the liquid tank is fixedly connected with a filter and a liquid level meter; an electric heating grid plate is arranged in the liquid tank which is filled with the non-Newtonian fluid; the overflow valve and the liquid tank are communicated with the bilateral sides of a miniature reciprocating pump respectively. According to the automotive automatic repair, buffering and energy absorption device, the automatic repair capability is achieved and the energy absorption effect is good; the temperature of the non-Newtonian fluid can be adjusted and accordingly the automotive automatic repair, buffering and energy absorption device can be suitable for the wide temperature range and various shape structures of energy absorption boxes; the energy absorption boxes can be recycled and accordingly the economic and environment-friendly effect is achieved.

Description

Technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a buffering energy absorbing device that can be automatically repaired and installed on a vehicle. Background technique [0002] The automobile energy absorbing box buffers and absorbs the energy in the collision through compression and deformation, reduces the damage to pedestrians and occupants in the collision, and improves the crash resistance of the automobile, thereby improving the safety of the automobile in a collision. In order to improve its energy absorption efficiency, manufacturers usually start with improving the mechanical properties of the material and changing the structure of the energy absorption box. The energy absorbing component in the prior art needs to replace the energy absorbing box after a collision, which causes the inconvenience of not being able to use the car in a short period of time, and at the same time increases maintenance costs.
