Emergency self-locking device preventing mistakenly stepping on accelerator

Abstract

The invention discloses an emergency self-locking device preventing mistakenly stepping on an accelerator. The emergency self-locking device comprises an accelerator foot rod and a base. The base is provided with a gearbox. The gear box is provided with an input shaft and an output shaft. The accelerator foot rod is fixedly connected with the input shaft. The output shaft is fixedly connected witha ratchet. A first pin shaft is fixedly arranged in the eccentric position of the ratchet. A driving rod is movably arranged on the first pin shaft in a sleeving mode. One end of a spring is connected with the driving rod, and the other end of the spring is connected with the ratchet. A pawl is arranged beside the ratchet. One end of the pawl is hinged to the base. The two sides of the pawl are each provided with a track plate. Track grooves are correspondingly formed in the two track plates. The two ends of a driving shaft are matched with the two track grooves. The side, close to the free end, of the pawl is arranged on the driving shaft in a sleeving mode. The middle part of the driving shaft is fixedly connected with a convex block. When the ratchet is fast started, the driving rod switches and strikes the convex block, the convex block drives the driving shaft and then drives the pawl to rotate towards the side close to the ratchet to clamp the ratchet. The emergency self-lockingdevice can lock the accelerator foot rod when the accelerator is mistakenly stepped on and improves the safety of driving.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an emergency self-locking device for mistakenly stepping on the gas pedal. Background technique [0002] Nowadays, cars have become one of the most important means of transportation for people to travel. With the rapid growth of vehicles, the road conditions are becoming more and more complex. At the same time, there are a large number of novice drivers. , but stepped on the gas pedal by mistake, it could have avoided accidents or just minor accidents, but caused vicious traffic accidents and heavy losses. Therefore be necessary to design a kind of device that prevents stepping on accelerator by mistake, to improve the safety of driving. [0003] For example, on November 25, 2015, a Chinese invention patent with the patent number ZL201520221239.1 and the name "Misstepping on the Accelerator Locking Device" was disclosed, which includes the accelerator and the lo...
