CN201951439U - Brake pedal capable of preventing a throttle from being used as a brake - Google Patents

Abstract

The utility model relates to a brake pedal capable of preventing a throttle from being used as a brake, belonging to the improvement of the brake pedal for vehicle. The object of the utility model is to provide a brake pedal capable of preventing the throttle from being used as the brake due to error stamping by changing the position of the brake pedal. The brake pedal deflects towards the right and then moves backwards, the front part of the brake pedal is low and the back part of the brake pedal is high. A slide way is arranged between the brake pedal and an acceleration pedal and the front end of the brake pedal is axially connected with a pedal trip axle and the pedal trip axle is fixed on a vehicle bottom board. The brake pedal slightly deflects towards the right and then moves backwards and the front part of the brake pedal is low and the back part of that is high. In order to satisfy the pedal stroke, the back edge of the pedal of a passenger car is higher than the floor by 100-150mm, the back edge of a commercial vehicle is not higher than the floor by 180mm. The pedal can vertically turn using the front edge as the turning axle.

Description

Prevent that mistake is with the brake pedal of throttle when brake

Technical field

The utility model relates to the improvement of automobile-used brake pedal.

Background technology

By present acceleration, brake pedal scheme, quicken, glancing impact to its corresponding pedal the limb action main points in full accord---" preceding stepping on ", firmly the position is also in full accord---forefoot.

Quicken, when braking is switched, specifically step at which pedal and depend on the judgement that by touch is made when pin is unsettled, in case misjudgment may cause " mistake is worked as brake with throttle ".In addition, the prominent emergency situation of meeting recognizes and want emergency braking, but right crus of diaphragm does not leave acceleration pedal at all during cruising, just directly steps on, and can cause " mistake is worked as brake with throttle " yet.The example report shows that dedicated driver in the prim of life also might " be worked as brake with throttle " by mistake.

Finish to have two of " stepping on brake pedal ", 1. finish limb action " push down on the pedal ".2. guarantee that the pedal of being stepped on must be a brake pedal." mistake is worked as brake with throttle "---expects to step on brake pedal and but stepped on acceleration pedal by mistake, illustrate in the existing pedal design to exist when 1. correctly making, be attended by and step on wrong pedal---danger of bend the throttle.Promptly existing pedal design can not guarantee that the pedal of being stepped on must be brake pedal or not be acceleration pedal at least with correctness 1..This is the root that causes " mistake is worked as brake with throttle ".

Summary of the invention

The purpose of this utility model is the brake pedal that prevents from by mistake throttle to be worked as brake that prevents that by brake pedal position being changed, just getting to mistake from stepping on.

Move after the utility model brake pedal deflection to the right also, low early and high after, between brake pedal and acceleration pedal slideway is arranged, brake pedal front end axle is connected on the pedal trip shaft, and the pedal trip shaft is fixed on the car bottom plate.

The utility model has the advantages that:

On pedal structure and layout, 4 improvement are arranged

1. brake pedal slightly moves after the deflection to the right also, and is low early and high after.For satisfying pedal stroke, to manned vehicle, the edge is than ground plate hight 100-150mm behind the pedal, and commercial vehicle/comm..vehicle does not exceed 180mm.But the edge is the upset of upset axis upper and lower before the pedal.

2. left side, the back side edge of brake pedal are suitably increased along the square edge that constitutes, form spacing.

3. also slightly deflection to the right of acceleration pedal.

4. be connected by slideway wear-resisting, low-friction material between acceleration pedal and brake pedal.

Acceleration, glancing impact have 2 improvement to the limb action of its corresponding pedal:

1. the essential of exercise to acceleration pedal is " preceding stepping on ", is " to step under the back to the essential of exercise of brake pedal.”

Firmly position to its pedal when 2. quickening is a forefoot, and glancing impact is a rear heel to the firmly position of its pedal.

Description of drawings

Fig. 1 is the utility model brake pedal position structural representation.

The specific embodiment

Move after the utility model brake pedal 4 deflection to the right also, low early and high after, 2 of brake pedal 4 and acceleration pedals have slideway 1, and brake pedal 4 front end axles are connected on the pedal trip shaft 3, and pedal trip shaft 3 is fixed on the car bottom plate.

The utility model carries out the process of glancing impact:

1, right crus of diaphragm (this moment, heel withstood on the slideway as fulcrum, sole control acceleration pedal) heel is pasting slideway pin is shunk, returns and remove that brake pedal---it is spacing that heel is run into brake pedal from acceleration pedal;

2, make use of momentum and step on 2 actions of brake pedal under the heel.A action is that natural reaction is moving, and need not that " pin is unsettled " reaches " searching " brake pedal in the recession process, during push down on the pedal, spacingly can hold heel again, prevents slippage.Do guiding with slideway, with spacing prompting pedal position and slippage when preventing push down on the pedal.Resultant effect is promptly to have prevented " mistake with throttle when brake " reliably, has shortened brake response opening time again.

During driver's normal driving, two legs slightly become " eight " font, and right crus of diaphragm meeting nature is to right avertence.Therefore, brake pedal and acceleration pedal be slightly to right avertence, makes accelerations, pin mobile more smooth and easy on slideway when braking is switched.

1. improvement project because of braking, when quickening right crus of diaphragm to the limb action main points of its corresponding pedal with firmly the position is different fully, so can guarantee object---the correctness of pedal that the limb action selection applies with the correctness of limb action.

2. limb action conforms to fully with the implication of corresponding pedal, is convenient to memory.Specifically:

Limb action " is stepped on " implication " advance "=quicken (pedal) before the forefoot

Limb action " rear heel (descending) is stepped on "=implication " stop "=brake (pedal)

Therefore, after so training was formed a habit when taking driving test, both can not obscure.

3. need in driving to quicken, when braking is switched, pin is pasting the slideway motion all the time, does not have unsettled process, seeks the pedal process, better safety action rapidly, link up, accurately.

Brake pedal be lower than acceleration pedal and brake pedal move slightly backward one suitable apart from the time, brake response can reduce opening time to some extent.

More than comprehensive, it is separately independently traditional that this patent has promptly followed automobile brake, acceleration pedal, can guarantee only just effectively to prevent " throttle is mistakened as brake " under the situation about will brake of what is the need in office on the mechanism again with the reaction of instinct limbs, with compared originally, change little, cost is low, and according to top conclusion, brake response can reduce opening time to some extent, stopping distance also can correspondingly shorten, and promptly has advance and has real feasibility again.

Claims (1)

1. one kind prevents that mistake is with the brake pedal of throttle when brake, it is characterized in that: move after the brake pedal deflection to the right also, low early and high after, between brake pedal and acceleration pedal slideway is arranged, brake pedal front end axle is connected on the pedal trip shaft, and the pedal trip shaft is fixed on the car bottom plate.
