Misoperation safety protection device for automotive accelerator pedal

Abstract

A misoperation safety protection device for an automotive accelerator pedal is added on an automobile and is used for preventing a safety accident caused by a misoperation to the accelerator pedal which is mistakenly used as a brake pedal. The misoperation safety protection device comprises the components of an accelerator pedal speed sensor, an automatic braking device and an electric control device. The misoperation safety protection device is characterized in that the accelerator pedal speed sensor is a mechanical-photoelectric sensor; the automatic braking device comprises a braking spring, a control electromagnet, a pawl, a braking lever and a braking connecting rod. The pedal speed sensor comprises a rotary photoelectric encoder. One end of the braking lever is provided with a reset pedal 241. A hinge for hinging the braking connecting rod with the brake pedal is an open hinge. The misoperation safety protection device has advantages of simple structure, simple mounting, no effect on an original automobile structure, no cab space occupation, no effect on normal operation, no requirement for operation habit change of an operator, high response speed, high reliability, effective capability of restoring normal driving through one-foot resetting, easy popularization, relatively high practical value and relatively high social benefit.

Description

technical field [0001] The invention relates to the technology of automobile accessories, in particular to a safety protection device for gas pedal misoperation. Background technique [0002] Existing car accelerator and brake systems are two independent systems, and the accelerator pedal has no speed limiting device, no matter how high the speed and how much strength the driver uses, the amount of fuel added to the accelerator can respond. In actual use, it often happens that in an emergency, the driver mistakenly presses the accelerator pedal for the brake at high speed, with the purpose of emergency braking, but the result is that the car not only fails to decelerate and brake, but accelerates with the maximum horsepower, causing car crashes and fatalities The tragic brush, resulting in countless serious traffic accidents. On March 1, 2015, a tragic accident in which nine people were killed and more than a dozen injured occurred at Shenzhen Baoan Airport shocked the worl...

Problems solved by technology

[0003] In order to solve this problem, an inventor once proposed a technical solution of a safety device, named "Safety Guarantee Device for Misstepping on the Accelerator Pedal of a Car", the patent number is 200620077215.4, which is characterized in that an accelerator pedal action sensor is connected under the accelerator pedal , the output end of the sensor is connected to the input end of the electric control device, and the output end of the electric control device is connected to the ignition switch of the automobile ignition coil and the electric control switch at the control end of the automobile brake master cylinder. The structure of this scheme is complicated, especially to modify the original product structure, resulting in the problem that the warranty cannot be guaranteed after modification, and it is difficult to popularize and apply
