Abstract
The utility model provides a kind of warning in advance brake gear.Mainly by installing proximity switch on brake pedal, when pin is placed near brake pedal, before chaufeur steps on brake, the proximity switch on brake pedal just perceives and will brake, and lights stoplight stop lamp, thus carries out warning in advance to vehicle below.Light stoplight stop lamp in advance to warn, can effectively prevent traffic rear-end collision, the security of the lives and property of the protection people, significant.
Description
Technical field
The utility model relates to automotive field, is specifically related to brake gear.
Background technology
The ratio of rear-end collision in traffic accident is very large, and incomplete statistics (insurance company, express highway have statistics), accident rate accounts for 40% to 80% of traffic accident.Braking effect is better, larger by the possibility knocked into the back.The anti-technology that knocks into the back of great majority, is all anti-ly oneself knock into the back others, seldom has and prevent others from knocking into the back oneself.Prevention is knocked into the back, great to the security of the lives and property Protection significance of the people.
Prevent the technology that knocks into the back more, be improved braking effect, have Distance geometry relative velocity between measuring machine motor-car, have and survey brake pedal pressure and displacement.But be all difficult to light stoplight stop lamp in advance, the pre-warning time leaving rear car for is few, and the ratio making rear-end collision occur is very high.
Existing stoplight stop lamp is stepping on brake pedal, and after brake pedal has displacement, trigger braking signal switch, stoplight stop lamp is lighted.This method, the time that stoplight stop lamp is lighted is more late, and the time stayed to rear car is few, and rear car has little time brake, and thus rear-end collision takes place frequently, and even many cars even hit.If motor vehicle energy lights stoplight stop lamp in advance, rear-end collision incidence just can be made to decline to a great extent.
Had a technology, setting be complete accelerator releasing time light stoplight stop lamp, thus before brake early warning rear car, this setting, although warning in advance rear car, but the probability of wrong report brake is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of warning in advance brake gear, it is characterized in that on brake pedal, install proximity switch and micro-switch, described micro-switch and the parallel connection of former braking signal switch, described proximity switch and the parallel connection of former braking signal switch.
Described proximity switch is condenser, inductance type, photo-electric, radar type.
The utility model, by installing proximity switch, micro-switch on brake pedal, when the pin of chaufeur is close to brake pedal, just triggers proximity switch, proximity switch brakes on lamp, warn rear car in advance, the reaction time stayed to rear car is many, effectively can prevent the generation of rear-end collision.
The utility model is changed less to original self-propelled vehicle, does not affect former car, easily promotes.
The utility model proximity switch, micro-switch and former car braking signal switch three are in parallel, even if there are two switch failures, still can light stoplight stop lamp, make driving safer.
Accompanying drawing explanation
Fig. 1 is the mounting structure figure of brake pedal and proximity switch, micro-switch.
Fig. 2 is the circuit diagram of proximity switch, micro-switch, former car braking signal switch.
Wherein 1-former car braking signal switch; The pin of 2-chaufeur; 3-micro-switch; 4-proximity switch; 5-brake pedal; 6-stoplight stop lamp.
Detailed description of the invention
Embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, micro-switch 3 is arranged on brake pedal, on brake pedal 5, installation by adhering proximity switch 4, can regulating close to distance of proximity switch 4.Installation by adhering proximity switch 4 is more better than exposed, and brake pedal 5 can be kept smooth.
The technology of proximity switch is very ripe, and proximity switch has the various ways such as condenser, inductance type, photo-electric, radar type, magnetic-type, cuts both ways.Such as inductance approach switch can perception metal object, insensitive to pin.The price of radar type proximity switch is higher, and speed of response is slower.Capacitive approach switch because price, reliability, can perception non-metal (pin), be applicable to the utility model and adopt.Reaction time faster capacitive approach switch is better.
As shown in Figure 2, the utility model adopts in PNP long open form capacitive approach switch 4 and former car braking signal switch 1 incircuit in parallel, micro-switch 3 and the parallel connection of former car braking signal switch 1 access in motor circuit, and former braking signal switch 1 has three parallel connections, and reliability is higher.
When braking, the pin 2 of chaufeur close to brake pedal 5 also do not step on brake pedal time, just trigger proximity switch 4, light stoplight stop lamp 6 in advance.
When the pin 2 of chaufeur contacts brake pedal 5, when brake pedal 5 does not also have a displacement, just trigger micro-switch 3, light stoplight stop lamp 6 in advance.
According to the different requirements of different people, proximity switch 4 and micro-switch 3 can not simultaneously be installed or install simultaneously and asynchronously enable, and namely only adopt proximity switch or micro-switch one to play a role.
In advance bright light mode can with brake after the bright difference of length, such as, can be flicker bright light.
In a word, brake pedal 5 is installed proximity switch 4, micro-switch 6, when the pin 2 of chaufeur is close to brake pedal 5, just triggers brake alarming in advance, effectively can prevent the generation of rear-end collision.
Claims (2)
1. a warning in advance brake gear, it is characterized in that proximity switch (4) and micro-switch (3) are installed on brake pedal (5), described micro-switch (3) and former braking signal switch (1) parallel connection, described proximity switch (4) and former braking signal switch (1) parallel connection.
2. warning in advance brake gear as claimed in claim 1, is characterized in that described proximity switch (4) is the proximity switch of condenser, inductance type, photo-electric or radar type.
