All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-6, the present utility model provides a technical solution:

the utility model provides a vehicle safety brake auxiliary device, including brake pedal 1, brake pull rod 2, accelerator pedal 3 and throttle lever 4, fixedly connected with triggers gasbag 5 between accelerator pedal 3 and the automobile body, trigger gasbag 5 rear end intercommunication has outlet duct 6 and intake pipe 7, it blocks ball 8 to slide in the outlet duct 6, outlet duct 6 outer wall has seted up venthole 9, outlet duct 9 is located and blocks ball 8 top, the intercommunication department rotation of outlet duct 6 and trigger gasbag 5 is connected with the diaphragm 10 that gives vent to anger, top fixed mounting has contact switch 11 in the outlet duct 6, it is equipped with intake diaphragm 12 to slide in the intake pipe 7, fixedly connected with contact ring 13 in the intake pipe 7, proximity switch is installed in the outside of contact ring 13, accelerator pedal 3 internally mounted has sharp telescopic link 14, the output rotation of sharp telescopic link 14 is connected with a set of connecting rod 15, the tip of connecting rod 15 is all rotated and is connected with adapter 16, pass through adapter 16 rotation between accelerator pedal 3 and the throttle lever 4 and be connected, brake pull rod 2 mid-mounting has and blocks telescopic link 17, contact switch 11 is used for switch on sharp telescopic link 14 and blocks telescopic link 17, proximity switch is used for closing sharp telescopic link 14 and blocks telescopic link 17.

When the accelerator pedal 3 is stepped on, the accelerator pedal 1 is stepped on to accelerate, and when the accelerator pedal 3 is stepped on, the accelerator pedal is stepped on at a constant speed and slowly, so that the lower trigger air bag 5 is extruded at a constant speed and slowly when the accelerator pedal 3 is stepped on, the trigger air bag 5 uniformly exits through the air outlet pipe 6, the blocking ball 8 is slightly jacked up, the air is discharged from the air outlet hole 9, when the accelerator pedal 3 is released, the port is opened in the air inlet diaphragm 12, and the trigger air bag 5 enters the air through the air inlet pipe 7 to restore the original state, so that normal oiling and deceleration can be realized, and the foot feeling and the like are not influenced.

When the air is discharged, the air flow naturally jacks up the air outlet diaphragm 10 so as to open the communication part between the triggering air bag 5 and the air outlet pipe 6, and when the air is discharged, the trend of outward flow of the air flow naturally acts on the air inlet diaphragm 12 to seal the air inlet pipe 7, so that the air flow can only go out from the air outlet pipe 6; the same principle is adopted, when the airbag 5 is triggered to enter air, the air inlet membrane 12 is opened, and the air outlet membrane 6 is blocked, so that one-way in-out of air is ensured.

In case of accident, if the accelerator pedal 3 is stepped on by mistake under the condition that the brake is required to be stepped on emergently, when the accelerator pedal 3 is stepped on emergently and rapidly, the triggering air bag 5 is rapidly extruded to give off air, a large amount of air is discharged from the air outlet pipe 6, the impact descending blocking small ball 8 with more and faster air flow is rapidly jacked up and then is beaten on the contact switch 11 to be contacted with the contact switch, the linear telescopic rod 14 and the blocking telescopic rod 17 are instantly connected when the contact switch 11 is contacted, the output end of the linear telescopic rod 14 is connected and retracted, the connecting rod 15 drives the switching shaft 16 to approach each other and retract, and then the connecting hole of the accelerator rod 4 is withdrawn, so that the accelerator pedal 3 and the accelerator rod 4 are disconnected, the accelerator is not increased even if the accelerator pedal 3 is stepped on to any degree, and the free state of the accelerator rod 4 is in the accelerator closing state; the output end of the blocking telescopic rod 17 is also retracted when the blocking telescopic rod is connected, and therefore the vehicle braking system can be rapidly braked by shortening the contracted braking pull rod 2 under the condition that the braking pedal 1 does not act. Therefore, when the accelerator pedal 3 is suddenly and rapidly stepped on by mistake, the accelerator matching is released, the accelerator is not filled and closed, meanwhile, the braking is realized, the further damage caused by mistakenly stepping on the accelerator is avoided, the situation that the accelerator is simultaneously filled with oil and braked is avoided, the effective and reliable emergency braking is realized, the transmission delay is greatly reduced through the contact switch 11 and the electric control linear telescopic rod 14 and the blocking telescopic rod 17, and the response is fast and timely.

When the unexpected situation is relieved, the corner naturally releases the accelerator pedal 3, the trigger air bag 5 is mobilized to be stretched when the accelerator pedal 3 automatically returns and is inflated inwards through the air inlet pipe 7, when the air inlet diaphragm 12 moves inwards and is close to or even in contact with the contact ring 13, the proximity switch is started, so that the linear telescopic rod 14 is controlled and the blocking telescopic rod 17 returns to the restoration state and is powered off, the linear telescopic rod 14 stretches out during the return process of the accelerator pedal 13, so that when the accelerator pedal 13 returns to the position where the accelerator pedal 13 is in butt joint with the accelerator rod 4, the switching shaft 16 is just pushed out into the connecting hole of the accelerator rod 4, and then the accelerator pedal 3 and the accelerator rod 4 are reconnected, and the subsequent normal use is not affected; meanwhile, the telescopic rod 17 is blocked from returning to the original position, the brake is released, and the brake is restored to a free state, so that the automatic brake can be realized through the brake pedal 1, the return is quick, and the use is convenient and flexible.

The rear wall of the triggering air bag 5 is communicated with a switching tube 18, the switching tube 18 is communicated with the air outlet tube 6, the outer end of the switching tube 18 positioned inside the air outlet tube 6 is rotationally connected with the air outlet membrane 10, a limit ring 19 is fixedly connected inside the air outlet tube 6, and the blocking ball 8 is positioned above the limit ring 19.

The blocking ball 8 is prevented from blocking the air outlet end of the transfer tube 18 by the limit ring 19, the air outlet membrane 10 is prevented from being influenced, and the blocking ball 8 can be forced by air flow of air outlet.

Wherein, intake pipe 7 tip fixedly connected with closed circle 20, intake diaphragm 12 are located the inside of closed circle 20 and the diameter of intake diaphragm 12 is greater than the diameter of closed circle 20 and is less than intake pipe 7 diameter. A light spring 21 is connected between the air intake diaphragm 12 and the contact ring 13.

Under normal and air-out conditions, the light spring 21 ensures that the air inlet diaphragm 12 is tightly attached to the closing ring 20, and a good sealing effect is achieved.

Wherein, outlet duct 6 and intake pipe 7 are located outside the carriage, and linear expansion link 14 and blocking expansion link 17 are linear motor or cylinder or electric putter or pneumatic cylinder. The contact switch 11 is a touch switch, a travel switch or a micro-click switch.

And the electric starting control is linked, so that the time delay is reduced, and the reaction speed is improved.

The end of the linear telescopic rod 14 is fixedly connected with a U-shaped block 22, the inner end of the adapter shaft 16 is fixedly connected with a connecting lug 23, and the connecting rod 15 is rotatably connected between the U-shaped block 22 and the connecting lug 23.
