The utility model content
The throttle system that the purpose of this utility model provides simply, accurately directly the action of mistake step on the gas exported with electric signal, be to gather mistake step on the gas action and with the throttle system of electric signal output, and the electric signal that will miss step on the gas drive the throttle system of special urgent error correction device.
Design of the present utility model is: the people may make the action of mistake step on the gas when flurried, different motion when the mechanism that mistake step on the gas action must make Das Gaspedal and its link produces with normal oiling, namely Das Gaspedal is bound to be subject to excessive strength with its mechanism that links.People refuel the strength of normal accelerator pedal and are generally less than 5 kilograms, the strength of mistake step on the gas action is generally greater than 10 kilograms, through many experiments, with mistake during step on the gas pedal be subjected to 10 kilograms of pressure to step on threshold value as mistake, difference is normal refuel action and the action of mistake step on the gas be reasonably, applicable, safety.So only need to pressure switch be set in Das Gaspedal and its mechanism that links, in Das Gaspedal is stressed just conducting of pressure switch when stepping on 10 kilograms of threshold values more than or equal to mistake, send the electric signal of mistake step on the gas, pressure switch does not need to experience less than mistake steps on the Das Gaspedal state of kinematic motion of threshold value, the methods simplification that gathers the mistake step on the gas.So only when having more than or equal to 10 kilograms of step on the accelerator strength, two conductiving points of pressure switch just contact and send electric signal, represent to have errorless step on the gas action with regard to the electric signal of available switching regulator.So this patent claims that this pressure switch is pressure activated switch 1.Certainly the strength with 10 kilograms of step on the accelerators triggers not necessarily more suitable special populations of pressure activated switch 1, can use the different elastic element of elasticity modulus instead to special population, and the switching threshold of change pressure activated switch 1, thereby the mistake that changes Das Gaspedal is stepped on threshold value.
As the application require preceence in first to file ［ 201120189726.6 ］, be that " pressure type low voltage electric switch " do not put down in writing and used elastic element with the action of " pressure type low voltage electric switch " identification mistake step on the gas.The application is on first to file " pressure type low voltage electric switch " setting position basis, change, increase, and position and the band of clearer and more definite pressure activated switch 1 have elastic component, the also further clear and definite structure of pressure activated switch 1, and the connecting structure of pressure activated switch 1 and existing Das Gaspedal linked system.
Structure of the present utility model is:
Be the band pressure trigger switch formula Das Gaspedal system that the correction phenomenon of taking throttle as brake is used, comprise the car body position 21 of Das Gaspedal 16 and Das Gaspedal 16 correspondences of automobile; Perhaps the car body position 21 of Das Gaspedal connecting rod 17 and Das Gaspedal connecting rod 17 correspondences is characterized in that: also comprise the energizing signal conv 35 that pressure activated switch 1 is connected with pressure activated switch 1;
Be provided with pressure activated switch 1 in the front of Das Gaspedal 16;
Or be provided with pressure activated switch 1 at the back side of Das Gaspedal 16, pressure activated switch 1 leaves normal oiling clearance space between the car body position 21 corresponding with Das Gaspedal, when being displaced to the stressed mistake that is in, Das Gaspedal 16 steps on the position of threshold status, car body position 21 contacts that pressure activated switch 1 is corresponding with Das Gaspedal;
Or the car body position 21 of Das Gaspedal 16 correspondences is provided with pressure activated switch 1, between pressure activated switch 1 and the Das Gaspedal 16, leave the Das Gaspedal 16 normal clearance spaces that move and need that refuel, step on the position of threshold status when Das Gaspedal 16 is displaced to the stressed mistake that is in, pressure activated switch 1 contacts with Das Gaspedal 16;
Or be provided with pressure activated switch 1 on Das Gaspedal connecting rod 17 surfaces towards car body,
Or be provided with pressure activated switch 1 at the car body position 21 of Das Gaspedal connecting rod 17 correspondences;
Take mistake step on the gas action the minimum force of Das Gaspedal 16 is stepped on threshold value as the mistake of mistake step on the gas; In the time of contacting conduction with two contacts of pressure activated switch 1, the elastic element elastic force of pressure activated switch 1 is switching threshold; The position that pressure activated switch 1 arranges makes switching threshold just in time express mistake and steps on threshold value, and namely the position that arranges of pressure activated switch 1 makes switching threshold and misses that to step on threshold value corresponding;
Pressure activated switch 1 is after therein elastic element is subjected to the switching threshold pressure distortion, two conductive contact pieces 25 of switch to be contacted, and produces the switch that conduction is connected;
Pressure activated switch 1 is connected with energizing signal conv 35, and energizing signal conv 35 converts the energizing signal of pressure activated switch 1 to control signal output.
The car body position 21 of described Das Gaspedal 16 correspondences refers to: in the normal fueling state of automobile, Das Gaspedal 16 refuel sense of motions pointed the fixed parts band of position, and be that Das Gaspedal 16 is refueled the fixed parts band of position that motion approached.
The car body position 21 of described Das Gaspedal connecting rod 17 correspondences refers to: in the normal fueling state of automobile, Das Gaspedal connecting rod 17 refuel sense of motions pointed the fixed parts band of position, and be that Das Gaspedal connecting rod 17 refuels the fixed parts band of position that motion approached.
The elasticity modulus setting pressure switching threshold that pressure activated switch 1 selects elastic element to be fit to, step on threshold value if the strength of setting pin accelerator pedal 16 is the mistake of Das Gaspedal 16 during more than or equal to 10 kilograms, mistake is stepped on threshold value makes the pressure activated switch 1 that pressure activated switch 1 can conducting stressed as switching threshold.Under the switching threshold state, 1 conducting of pressure activated switch.The strength of pin accelerator pedal 16 is stepped on threshold value less than mistake, and pressure activated switch 1 is stressed less than switching threshold, 1 one-tenth off-state of pressure activated switch, and throttle normally refuels the raising speed of a motor vehicle.
As long as connect with the mains at two conductive contact pieces 25 of pressure activated switch 1, when 25 contact of two conductive contact pieces, pressure activated switch 1 just can output electrical signals.This electric signal is as the sign of wrong step on the gas behavior, and as the actuation signal of follow-up correction mistake step on the gas action.
In other words, make two contacts of pressure activated switch 1 can contact the minimum strength of conducting electricity, the minimum strength that the people sends when needing not be equal to the mistake step on the gas.Will send electric signal with two contacts contact conduction of pressure activated switch 1 and represent wrong step on the gas behavior, these two key elements cooperation ability Corrects of minimum strength ［ being switching threshold ］ that conduct electricity the position that then will arrange with pressure activated switch 1 and contact minimum strength that the people sends during step on the gas by mistake ［ is stepped on threshold value ］ by mistake.That is to say that it is to represent to step on threshold value with the position of pressure activated switch 1 setting and the cooperation of switching threshold that the mistake of missing step on the gas is stepped on threshold value by mistake.If it is 10 kilograms that mistake step on the gas mistake is stepped on threshold value, pressure activated switch 1 is arranged on the Das Gaspedal connecting rod 17 between Das Gaspedal 16 and Das Gaspedal 16 run-on points, because the power of pressure activated switch 1 back of the body is shorter than the power back of the body of Das Gaspedal 16, according to lever principle, switching threshold is that two contacts of pressure activated switch 1 can contact when conducting electricity, and the minimum elastic force of the elastic element of pressure activated switch 1 should be greater than 10 kilograms.If it is constant that setting mistake step on the gas mistake is stepped on 10 kilograms of threshold values, but the position that pressure activated switch 1 arranges is different, the switching threshold of elastic element is difference also.Generally speaking, mistake step on the gas mistake is stepped on the switching threshold that threshold value is not equal to elastic element.So, fixing pressure activated switch 1 of switching threshold can only be arranged on some ad-hoc locations of Das Gaspedal 16 or Das Gaspedal connecting rod 17, just can make 1 normal operation of pressure activated switch, be switching threshold could correction mistake step on threshold value, namely the position that arranges of pressure activated switch 1 makes switching threshold and misses that to step on threshold value corresponding.
Pressure activated switch 1 is to experience the stressed device of Das Gaspedal 16 and Das Gaspedal connecting rod 17, so can pressure activated switch 1 be set on Das Gaspedal 16 or Das Gaspedal connecting rod 17 surfaces towards car body, perhaps be provided with pressure activated switch 1 at the car body position 21 of Das Gaspedal 16 or Das Gaspedal connecting rod 17 correspondences.
Because pressure activated switch 1 is located on the Das Gaspedal connecting rod 17, or these two positions can be avoided driving on the indoor floor on the car body position 21 of Das Gaspedal connecting rod 17 correspondences feet blanket, the article overslaugh pressure activated that drops switch 1 are normally stressed.From the reliability aspect of pressure activated switch 1 impression mistake step on the gas action, pressure activated switch 1 is located at Das Gaspedal connecting rod 17 surfaces towards car body, or there is preferably reliability at the car body position 21 that is located at Das Gaspedal connecting rod 17 correspondences.

This mistake stepping accelerator error correction device with inching clutch is to be only applicable to carry out error correction to missing the step on the gas action, is used for can producing on the automobile device of Quick fastening sudden stop.Emergency brake requires fast, and the shift length of the existing brake machinery of pulling can only be very short time, and as long as the Extensible of the stay cord 3 that namely brakes is about 10.0 centimetres.So need only a depression ring 10 from dynamic interlocking teeth dish 5, can only block a circle brake stay cord 3 in this depression ring 10, its structure be " recess width of depression ring 10 is identical with the diameter length of brake stay cord 3; or the recess width of depression ring 10 is slightly larger than the diameter length of the stay cord 3 that brakes ", brake stay cord 3 can not at will be moved at depression ring 10, or removable position is very little.Depression is encircled the advantages that can only block a circle brake stay cord 3 in 10: the shift length of brake stay cord 3 is accurate, i.e. fine motion and accurate.Brake stay cord 3 precisely is that shift length guarantees accurately by the position that Volume enters to be retracted in the depression ring 10.The length that moves of brake stay cord 3 precisely and the position precisely be the necessary condition of braking as driving, and the clutch type electric hoister of general common heaving line complex structure not only, out of reach is used for driving braking automobile need to brake length that stay cord 3 moves precisely and accurately requirement of position.
Preferably bottom 14 axis projections with the mistake stepping accelerator error correction device of inching clutch depression ring 10 are cam 15 shapes.Cam 15 has the linear velocity characteristics different from cireular frequency when rotating, and rotates in circumference at first that starts, and cam 15 can be exported first faster linear velocity and less pulling force to the stay cord 3 that brakes, and then slows down gradually linear speed and increases pulling force.This just in time is fit to brake stay cord 3 pulling vehicle braking mechanisms realizes in the brake process that the coupling in the front and back period needs to linear speed speed and pulling force.If but the bottom 14 of depression ring 10 is circle wheels, satisfy brake stay cord 3 and start fast brake, then round wheel diameter is larger, and the circle wheel diameter will will be joined more greatly the low-tension motor 6 of relatively high power, could satisfy brake stay cord 3 pulling force of brake later stage needs.So cam 15 not only makes 3 pairs of vehicle braking mechanisms of brake stay cord export the flexible braking effect with buffering, also can reduce power and the volume of low-tension motor 6, makes low-tension motor 6 easier best position that finds in automobile.If the volume of the low-tension motor 6 that uses is too large, might in some automobiles, can not find the installation site, make the mistake stepping accelerator error correction device with inching clutch can not be used for these automobiles.
When active jaw dish 4 with from dynamic interlocking teeth dish 5 during in released state, the major axis of cam 15 is positioned at that side near dental inlay disk casing 11 rope guiding holes 12; Brake stay cord 3 is at the point of connection of depression ring 10 bottoms 14 cams 15, with the line of dental inlay disk casing 11 rope guiding holes 12 are cam 15 tangent lines.Cam 15, brake stay cord 3 are the position of this a kind of cooperation at the point of connection of depression ring 10 bottoms 14 cams 15, dental inlay disk casing 11 rope guiding holes 12 threes at brake state not, and guarantee obtains brake stay cord 3 flexible braking effect.Had in the position of this a kind of cooperation of brake state not, when active jaw dish 4 begins to drive when carrying out brake from dynamic interlocking teeth dish 5, cam 15 spurs brake stay cord 3 greater than the major axis projection of auxiliary circle faster with linear velocity, when about 180 degree angles have been rotated in 4 drivings of active jaw dish from dynamic interlocking teeth dish 5 after, the minor axis of cam 15 part slows down with linear velocity and the larger mode of pulling force spurs brake stay cord 3, this just in time be adapted at approaching brake later stage brake stay cord 3 should displacement little and requirement that pulling force is large.
The girth of depression ring 10 is 5.0-15.0 centimetres.The depression that this girth limits is encircled 10 sizes, and the pivot angle of depression ring 10 is rotating in 360 degree, just can reach quick pulling brake stay cord 3 and produce the length that braking effect need to move.
" mistake step on the gas " described in the utility model refers to the driver in the time should touching on the brake pedal, the behavior of the Das Gaspedal of stepping on mistakenly, i.e. the faulty operation behavior of " phenomenon of taking throttle as brake ".
Elastic element described in the utility model comprises pressure spring, dish formula bouncing plate, also comprises having elastomeric sponge, rubber, damper etc.
Advantage of the present utility model: can directly obtain mistake step on the gas signal, do not need pressure sensor with microelectronic circuit to weight different foot throttle behaviors analyze the step on the gas behavior that misses of finding out.Can express accelerator pedal displacement as long as pressure activated switch of the present utility model is arranged on, and can express the ad-hoc location of Das Gaspedal strained condition, just can obtain mistake step on the gas switched electrical signal with the method for directly setting the switching threshold of elastic element again.Method with the switching threshold of setting elastic element, the pressure sensor that has replaced microelectronic circuit to electric pressure signal analysis find out the signal analysis process of mistake step on the gas electric signal, the method with Push And Release that is to say has replaced continuous signal is advanced the method that letter is analyzed, replace complicated electronic circuit with simple machinery, replaced the pressure sensor of easily variation of performance perameter, poor work stability, the unpredictalbe microelectronic circuit of reliability with good reliability, the elastic element that is difficult for automatically changing.The utility model is particularly suitable for requiring the work of high, the paroxysmal car emergency acquisition of signal of good reliability.
The mistake step on the gas switched electrical signal direct drive motor that available Das Gaspedal of the present utility model system sends improves for the reliability of correcting the behavior of mistake step on the gas and convert to brake.And the pressure activated construction of switch is simple, cost is low.
