Abstract

The invention relates to the technical field of vehicle manufacturing, and specifically discloses an auxiliary brake device for preventing misstepping on the accelerator, comprising a base, a flexible top plate and a non-Newtonian fluid, the base is a shell with an upper opening, and the flexible top plate is sealed and connected to the upper opening of the base It forms a closed cavity with the base, the flexible top plate is made of flexible material, and is used to contact and cooperate with the underside of the accelerator pedal of the vehicle, and the non-Newtonian fluid is filled in the closed cavity. Based on the solid-liquid phase properties and rheological relationship of the non-Newtonian fluid, the invention can effectively avoid traffic accidents caused by the driver stepping on the gas pedal by mistake. It has strong practicability and low cost. Compared with other braking safety auxiliary devices , the process is simpler, the life is longer, and the disassembly and assembly are flexible and convenient, without affecting the driving performance and driving experience of the original car.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a non-Newtonian fluid-based accelerator anti-accidental braking auxiliary device. Background technique [0002] Many scholars and automotive researchers at home and abroad have conducted investigations and researches, and put forward improvement and design schemes for the current automobile accelerator and brake mechanisms. Generally, they can be divided into two categories: pure mechanical and electromechanical. [0003] The main working principle of the purely mechanical brake assist device is to judge whether the accelerator pedal is accidentally stepped on according to the force or angular velocity of the accelerator pedal, and use the mechanical linkage device to realize the automatic braking of the vehicle. For example: an anti-accidental accelerator device for automobiles, which realizes that when the driver steps on the accelerator by mistake, the accelerato...
