Description

A kind of Das Gaspedal that has emergency braking

Technical field

The utility model relates to a kind of locomotive accelerator pedal device, relates in particular to a kind of accelerator pedal device that has emergency braking function.

Background technology

Traditional motor vehicle gasoline throttle and brake pedal all are independent complete operation work, use inconvenience, during emergency braking, need first pine tar door, again pin is moved on to brake foot plate from Das Gaspedal, could brake then, What is more is mistakened as brake with throttle, leads to major traffic accidents.

Number of patent application is the patent of invention of 90106372.X and 03100321.4, provides a kind of respectively and can have brake and the pedal combined of throttle concurrently.Though these two kinds of pedals with self-propelled vehicle get throttle, braking pedal mechanism unites two into one, and can not solve when emergency situation, easily throttle is mistakened as the problem of brake.

Number of patent application is the patent of invention of 99124639.X, a kind of device that throttle and brake is designed to one is provided, this device becomes that separate pass is the preferential relation of brake between in the past throttle and the brake, can directly brake under " oilings " state, need not the pine tar door and moves pin.Though it is easy and simple to handle that this device has, no non-cutting time, vehicle such as is under the driver control at any time at advantage, but its device is complicated, and reliability is not high.

Summary of the invention

Embodiment of the present utility model proposes a kind of Das Gaspedal that has emergency braking, has the function that can directly brake under " mistake is refueled " state, has simple in structure, high reliability features.

For achieving the above object, embodiment of the present utility model adopts following technical scheme:

A kind of Das Gaspedal that has emergency braking comprises Das Gaspedal, air cylinder device, braking circuit, it is characterized in that: described Das Gaspedal bottom is fixed on the self-propelled vehicle by hinges, and the middle part of Das Gaspedal has hinges; Air cylinder device comprises piston rod, piston rod retracing spring, exhausr port, cylinder block, tracheae, air valve, air cushion, air cushion retracing spring, piston, one end of described piston rod is connected with the hinges at described Das Gaspedal middle part and constitutes revolute pair with Das Gaspedal, in rod chamber, piston rod is provided with the piston rod retracing spring; Described exhausr port is opened the rodless cavity at cylinder block, and is made up of minor diameter exhausr port, major diameter deflation hole, and described minor diameter exhausr port leads to outside the cylinder block, and is connected with tracheae; At the outside external part of described minor diameter exhausr port air valve is set, to regulate extraction flow; At cylinder block two through holes are set, are communicated with the major diameter deflation hole, the braking circuit contact all is set in each through hole, and sealing; Described air cushion is made of minor diameter air cushion, major diameter air cushion, and the diameter of described minor diameter air cushion is bigger than minor diameter exhausr port, and is installed in the major diameter deflation hole, and its free end is connected by the air cushion retracing spring with tracheae; Described major diameter air cushion is conductive material, and its diameter is littler than major diameter deflation hole, and is installed in outside the major diameter deflation hole, and when air cushion retracing spring initial condition, major diameter air cushion and major diameter deflation hole leave the gap; Described braking circuit comprises switch, power supply, braking motor, wherein, switch is to be made of the major diameter air cushion that the braking circuit contact in two through holes and described conductive material are made, described switch one end is connected with positive source, the other end is connected with a connection terminal of braking motor, and another connection terminal of braking motor is connected with power cathode.

The utility model principle of work: when chaufeur when slowly trampling Das Gaspedal, cylinder rodless cavity inner air pressure slowly changes, and its inner air slowly emits by exhausr port, and air cushion and air cushion retracing spring thereof do not move, braking circuit is disconnected, and braking motor does not start; When chaufeur under the emergency braking situation, mistake has been trampled Das Gaspedal, at this moment cylinder rodless cavity inner air pressure sharply raises, make and to act on thrust on the air cushion greater than the spring force of air cushion retracing spring, air cushion is to exhausr port one lateral movement, the switch closure that the major diameter air cushion that braking circuit contact in described two through holes and described conductive material are made constitutes, this moment, brake circuit was connected, the braking motor emergency braking, the while exhausr port also air cushion of passive movement blocks up, trample throttle again and then become more difficult this moment, thereby further eliminate the influence that " mistake is refueled " brings.

The Das Gaspedal that has emergency braking that the utility model embodiment provides; compared with prior art; has simple in structure, high reliability features; can under " mistake is refueled " state, realize the braking motor emergency braking function; blocked up by air cushion because of exhausr port simultaneously; trample throttle again and then become more difficult, thereby realize the bidirectional protective function.
