Mechanical centrifugal vehicle accelerator misapplication prevention safety assistance device

Abstract

The invention discloses a mechanical centrifugal vehicle accelerator misapplication prevention safety assistance device. The device comprises a first gear and rack mechanism, a second gear and rack mechanism and an internal meshing ratchet wheel mechanism connecting the first gear and rack mechanism and the second gear and rack mechanism. A pawl of the internal meshing ratchet wheel mechanism is connected with a centrifugal push rod mechanism, the pawl and the centrifugal push rod mechanism are arranged at the output end of a gear shaft of the first gear and rack mechanism, a ratchet wheel is arranged at the input end of a gear shaft of the second gear and rack mechanism, the two gear shafts are arranged in a supporting shell through bearings, and two racks are sleeved with return springs. When an accelerator pedal is mistakenly treaded and quickly pressed, the gear shaft of the first gear and rack mechanism is driven by the racks to quickly rotate, the centrifugal push rod mechanism generates centrifugal force to drive the pawl to open and be meshed with the ratchet wheel, and the ratchet wheel drives the gear shaft of the second gear and rack mechanism to rotate so that the racks can drive a brake pedal to be pressed downwards, and braking is achieved. The device is simple in structure, the performance of the original structure is not affected, and the braking performance of the device is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of vehicle safety facilities, in particular to a mechanical centrifugal vehicle accelerator anti-misstepping safety auxiliary device. Background technique [0002] With the continuous increase of motor vehicles, while automobiles bring convenience to human beings, they also bring hidden dangers to public safety, and traffic accidents cause unnecessary losses of human life and property. Since the first traffic accident in which pedestrians and motor vehicles collided and died in 1896, more than 34 million people have died in road traffic accidents all over the world, and more than 500,000 people die in traffic accidents every year, and about 10 million people are injured. The traffic accidents in our country are also increasing year by year with the rapid increase of car ownership. In 2010, a total of 3,906,164 road traffic accidents were reported across the country, including 219,521 road traffic accidents ...

AI Technical Summary

Problems solved by technology

[0007] In short, there are still many problems and defects in the existing technology: (1) most of them are only theoretical, and there is no real thing at present; (2) the system is too complicated, the cost is too high, and it is not easy to popularize; (3) the feasibility of some patents It still needs to be verified, and the internal structure of the car has not been taken into account; (4) It can only realize some functions, which can prevent the accelerator from being stepped on by mistake, but it does not realize the function of braking in time, which will still cause accidents; (5) The reliability has not been passed Verification, the actual effect is not yet known
