Abstract

The utility model relates to a prompting device for driving dynamic and brake, characterized in that a prompting bulb is arranged on the obvious position of the rear of a car; a control switch is formed by the connecting in series an accelerator switch, a clutch switch, and the control circuit switch of a handbrake; the improved switch structures are arranged on the position of the interlocking bar of a foot pedal, the position of the link gear of the accelerator of a carburetor, the position of the shifting fork arm of a clutch, and the position of the display lamp switch of the handbrake. The utility model has the advantages that the reaction time of a driver in the back car is shortened so that the driver can prepare to brake in advance to get not less than 0.3 seconds reflection time, and the rear end collision accidents is reduced effectively, being suitable for vehicles sending out prewarning information to back vehicles.

Description

Drive and dynamically reach the brake suggestion device

The utility model belongs to car lighting and signalling set, and particularly a kind of vehicle of rearward trailing send and drive Dynamic Signal, point out the warning light of brake information in advance.

Run at high speed in the traffic accident of vehicle in the city, the self-propelled vehicle rear-end collision is occupied significant proportion.The generation of rear-end collision is because chaufeur is seen dangerous situation, taked brake measure, come into force the overall process required time above due to the reaction time to braking.By analysis, driver reaction time by reflection, move pin, three stages of trampling form, reflective stage is from seeing danger, through judging, determine that brake will mobile right crus of diaphragm, about 0.4 second; Moving the pin stage and be pin moves on to from acceleration pedal (throttle) and needed for 0.25 second on the brake pedal (brake) approximately; The stage of trampling is that pin is stepped on brake pedal and come into effect to braking, in about 0.1 second, amounts to the reaction time and is about for 0.75 second.This wherein moves pin and to trample required 0.35 second be essential, has only 0.4 second of reflective stage, if can shorten 0.1～0.25 second, then can greatly effectively reduce the generation of rear-end collision.Existing brake indicating lamp, brake indicator, the leading self check of brake, crashproof alarm device all do not have the dynamic forewarning function of driving.

The purpose of this utility model is, be provided with one in the motor vehicle tail increase and drive the dynamic reminding lamp, the switch of warning light is arranged on the throttle linkage mechanism place of stretcher gangbar position and carburettor and the shift fork arm place of power-transfer clutch, when automobile is regained throttle (loosen the clutch, unclamp hand braking), warning light is bright, show braking, move pin in advance to brake pedal, do brake and prepare with car chaufeur after the early warning.To shorten the reflective stage time of chaufeur, reduce the generation of rear-end collision.

Driving of the present utility model dynamically reaches the brake suggestion device, form by prompting bulb, master cock and source switch, the prompting bulb is located at the above the fold of automobile tail, source switch is the ignition lock of self-propelled vehicle, it is characterized in that, master cock is composed in series by the contactor of Throttle Opening Control, clutch control, hand braking control, and the throttle control circuit switch is arranged on accelerator pedal gangbar position, or the throttle linkage mechanism of carburettor place; The clutch control circuit switch is arranged on clutch foot plate gangbar position, or clutch slipper yoke arm place; Hand braking control circuit switch is arranged on original hand braking display lamp switch place.

Above-mentioned control circuit switch is made up of switch body and upper and lower contact, it is characterized in that, forms normally closed contact by positive and negative two utmost point fixed contacts on conducting contact on the drive link and the switch body, is connected with switch body bottom surface two plugs; Form open contact by positive and negative two utmost points and intermediate insulation interlayer on the following armature contact face of pilot bar, be connected with switch body bottom surface two plugs; The mating surfaces of conducting contact and following armature contact is the wear-resisting clear certainly conduction of corrugated inclined-plane, and the ripple direction is vertical mutually, and the side is provided with the return reed.

Using method of the present utility model is; When self-propelled vehicle is in to put one's foot down, during acceleration mode, warning light extinguishes, expression travel normal, safety; When not quickening, when regaining throttle, turning circuit, warning light is bright, is deceleration regime this moment.Back car chaufeur is received throttle at once according to the early warning signal of the display lamp of front truck, pin is moved on to carry out the brake preparation on the brake pedal, in case the front truck stoplight stop lamp is bright, back car driver just can depress brake pedal rapidly, can win 0.25 second, so that the reflective stage time in 0.3 second; As will speed up pedal and depress a little, warning light promptly extinguishes; When withdrawal put in place as acceleration pedal, warning light was bright; When the automobile neutral slided, warning light was bright and do not go out.During gear shift, depress power-transfer clutch, cut off, warning light does not work; When the tension of stopping is hand braking, cut off, warning light goes out; Only regain throttle when unclamping hand braking and power-transfer clutch, warning light just can be bright.

The control circuit switch body is installed on the corresponding car body position, and its drive link contacts with the movable part of control mechanism, and the plug switch on gets final product.

The utility model has the advantages that: the reflective stage time that can shorten chaufeur, performing braking brake in advance prepares, in case the front truck stoplight stop lamp is bright, back car chaufeur only need be finished (promptly the trampling the stage) action that touches on the brake, and finishes brake, play the effect that gives warning in advance, can win and be not less than 0.3 second time, finish the brake overall process, as per hour 20 kilometers of the speed of a motor vehicle, 0.3 can win 1.65 meters second, reduces the generation of traffic rear-end collision effectively.

Below in conjunction with drawings and Examples, the utility model is further described.
