Embodiment 2

[0031] 4. The integrated structural design of the door inner bracket and the new micro-nano composite liquid energy-absorbing buffer box, such as Figure 5 shown. The outer layer of the bracket is designed as an integrated micro-nano composite liquid energy-absorbing buffer box 18, and the inner layer of the bracket is a bracket 19 made of carbon fiber composite material. Among them, the nano-porous structure inside the micro-nano composite liquid energy-absorbing buffer box uses polyurethane porous nano-foam, and the liquid uses deionized water. The rubber sealing ring is used, the piston is made of carbon fiber polyetheretherketone composite material, and the piston structure is made of carbon fiber polyetheretherketone material. The specific buffer box parameters are 300mm in length, 20mm in width, and 30mm in height, and the length of the bracket is 300mm, 20mm in width, and 20mm in height.

Abstract

The invention provides a design and manufacturing method of a novel energy absorption structure vehicle door, aiming at the defects that the existing vehicle door is insufficient in safety protectionstrength, large in energy consumption and low in density. The novel energy absorption structure safety buffer energy discharge is conversion of external force acting to energy of other forms through deformation, a nano-porous structure and a fluid are mixed into a composite structure, and the liquid is extruded into nano-porous ducts under the impact of the external force, so that the mechanical energy is converted into a solid-liquid interface, external force buffering is realized, and the effect of safety protection of the vehicle door is achieved. The nano-porous structure has the advantages that the material can be repeatedly used, such that the cost is saved, the buffer distance is long, and the safety protection performance is high.

Description

technical field [0001] The invention provides a design and manufacturing method of a novel energy-absorbing structure door, which belongs to the field of automobile design and manufacturing. Background technique [0002] The safety protection of automobiles has always been a basic safety issue in the automobile era. Research on the design and manufacture of automobile safety protection structures is the fundamental guarantee for safe driving of automobiles. The design of the passive safety of automobiles is carried out around the collision resistance of the automobile structure, in which the absorption characteristics of the automobile door structure to the collision energy are mainly studied, and the energy absorbed by the body is maximized under the premise of ensuring the safety space of the occupants, so that the transmission of the body The collision energy is at a minimum. The higher the strength of the car door, the higher the impact energy. For this reason, people h...
