Description
Technical field
The utility model belongs to technical field of automobile parts, relates to a kind of brake gear, is specifically related to a kind of dead-man's device of mis-accelerator pressing.
Background technology
General skilled driver is in case of emergency, and the right crus of diaphragm of step on the accelerator " thinks without brain " that moving past the left side steps on brake " just unconsciously ", and this is the reaction of natural instinct.And this reaction of new hand does not also form, and feelings are just nervous when having met burst, and right crus of diaphragm is not mobile just directly to step down.In recent years, along with the very big improvement of people's material life, the private car owning amount sharply increased, and " road killer " quantity constantly increases, and in the traffic accident that has led to, having much is in case of emergency, and chaufeur is stepped on throttle and produced when brake.For preventing the generation of this type of traffic accident, the anti-locking system of development accelerator instead of brake is very necessary, and accelerator stepping misoperation preventing also becomes the research direction of a lot of individuals and mechanism, has also designed a lot of anti-error devices of stepping on and relevant patent.But design is complicated mostly, and adopts electronic systems such as pressoreceptor, velocity receptor, very easily causes interference, causes emergency brake to be lost efficacy.
The utility model content
Technical problem to be solved in the utility model is that the accelerator instead of brake at present existence prevents system architecture principle complexity, there is the weak point of violate-action in electronic system, proposes a kind of mis-accelerator pressing dead-man's device simple in structure, safe and reliable, easy to install.
The technical scheme that the utility model mis-accelerator pressing dead-man's device adopts is: it comprises Das Gaspedal, brake pedal and brake equipment, described brake equipment comprises two-point form taking-up device and solenoid circuit, the upper end of two-point form taking-up device is connected the rearward end of Das Gaspedal by taking-up device ribbon I, the lower end of two-point form taking-up device by taking-up device ribbon II be fixed on spacing lower baffle plate above, one end of the following connection spring of spacing lower baffle plate, the other end of spring is fixed, between two-point form taking-up device and the spacing lower baffle plate spacing overhead gage is set, spacing overhead gage is provided with switch contact I and the switch contact II that is isolated from each other in the solenoid circuit, switch contact I and switch contact II and spacing lower baffle plate flexibly connect, described solenoid circuit also comprises power supply and electromagnet, both ends of power is electrically connected with switch contact I and electromagnet respectively, electromagnet is electrically connected with switch contact II, and the electromagnet top is over against brake pedal.
Preferably, also can connect electro-delay system in the described solenoid circuit, to realize the lasting brake in the setting-up time.Delay timer can be set delay time, so that solenoid circuit kept connecting in the time of setting, also namely keeps brake pedal to continue to be in braking state, the preshoot phenomenon of avoiding inertia to cause.The setting of concrete time can adjust accordingly according to vehicle and cargo capacity size.
The below of described Das Gaspedal arranges a Das Gaspedal strong point, and the setting of Das Gaspedal supporting point position is as the criterion can realize that Das Gaspedal is rotated, and convenient repacking also can be set according to the original accelerator pedal position of automobile.Das Gaspedal is not when working: the front end is in the state of upwarping, and rearward end is not carried out rigid fixing, but is fixed on the base by spring tension.Therefore the position that the underfooting is stepped on during step on the accelerator is the leading section of Das Gaspedal, can drive the brake equipment that the Das Gaspedal rearward end connects and normally move, the emergency brake when namely guaranteeing normal oiling when normal step on the accelerator and mis-accelerator pressing.
The below of described brake pedal arranges a brake pedal strong point, and the setting of brake pedal supporting point position is as the criterion can realize that brake pedal rotates, and convenient repacking also can be set according to the original brake pedal position of automobile.Brake pedal is not when working, and the front end is in the state of upwarping.Under the prerequisite that does not hinder the normal circumstances brake, the position over against electromagnet on the brake pedal can arrange alnico magnets, when mis-accelerator pressing, can increase the suction between electromagnet and the brake pedal, and brake can be responded more rapidly and effectively.
When described electromagnet suction is set to general male sex's emergency braking 2 times of leg-power, i.e. 300～350N.
Displacement between described spacing overhead gage and the spacing lower baffle plate is 5～10 millimeters, so the throttle open amount is very little.When mis-accelerator pressing, can brake by instantaneous unlatching electromagnet, volume read-out then can be ignored.Because during normal step on the accelerator, spring can not produce the deflection more than 3 millimeters, so the displacement minimum value gets 5 millimeters, but displacement setting solenoid circuit closure smoothly may cause mis-accelerator pressing too greatly again the time, so higher limit is got 10 millimeters.
Described power supply can be used vehicle power, is as the criterion with the electric weight that the required suction of electromagnet can be provided.
Described taking-up device can adopt the car belt taking-up device, also can redesign as required, to reach as reducing usefulness such as volume.
Extract ribbon power when the elastic-restoring force of described spring is the taking-up device normal operation out 1.5 times, to keep normal mode of operation.The size of extracting ribbon power during general taking-up device normal operation out is 2N～7N, and therefore, the spring restoring force needs greater than 10.5N.Therefore this device medi-spring restoring force numerical value is 11～16N.
The utility model device designs thereby cause the different action of two-point form taking-up device according to normal step on the accelerator and mis-accelerator pressing significantly acceleration/accel difference between the two in emergency circumstances.The two-point form taking-up device is the core parts of the utility model device, and its upper end links to each other with the Das Gaspedal rear end by ribbon, and the lower end links to each other with the free end of the spring that an end is fixed.For taking-up device, can not locking when acceleration/accel is lower than 0.8g, locking immediately when acceleration/accel is higher than 2g.When normal step on the accelerator, acceleration/accel is generally in 0.8g, even also can not surpass 0.8g during the hot refueling door, spring force this moment pedal pull ribbon when slowly refueling overcomes the inner restoring force that reclaims wind spring, it is motionless that two-point form taking-up device position keeps, thereby this moment, throttle can normal operation.When accelerator instead of brake, because acceleration/accel is big, the general violent acceleration/accel of stepping on surpasses 2g, and the Das Gaspedal rear end drives the ribbon rapid movement, the inner latching device work of two-point form taking-up device, ribbon is stuck, when pedal continues to depress, can drive on two-point form taking-up device and the lower end spring and move, make the solenoid circuit closure, the powerful electromagnetic force of electromagnet moves down brake pedal automatically, thereby reaches the purpose of brake.Simultaneously, spacing overhead gage is when the taking-up device locking, and restriction lower end spring continues to stretch, and prevents that throttle from continuing to strengthen, and therefore the combined action by spacing overhead gage and spacing lower baffle plate can the restraining spring amount of tension, makes Das Gaspedal can not continue to depress.
Taking-up device structure and principle of work:
In taking-up device inside, a spring provides turning effort power (or moment of torsion) for spool.Its meeting spinning reel is in order to roll any lax ribbon.During normal operation, when Das Gaspedal is slowly refueled when pulling out ribbon, spool is left-hand revolution, and makes continuous spring also along the equidirectional rotation, and the spool of rotation is the anti-spring of having turned round just; If reduce throttle, then Das Gaspedal can be unclamped ribbon, and spring will tighten up, and the clickwise spool, until making the ribbon tensioning.In case of emergency, when brake and during mis-accelerator pressing, Das Gaspedal can be depressed fast, the taking-up device of design utilizes the speed of spool rotation as activating power with throttle.Its core parts are centrifugal clutchs---a kind of fork that increases the weight of that is installed on the spinning reel.When spool slowly rotated, fork was not swung, and a spring makes it remain on original position.But when violent step on the gas pedal, spool is with fast rotational, what centnifugal force ordered about fork increases the weight of to hold outside swing, the fork of elongation can promote the cam on the taking-up device shell, and cam links to each other with a pivot ratchet by sliding pin, when cam moves on to the left side, sliding pin can move along the notch of ratchet, this can pull ratchet into link to each other with spool rotation ratchet, and ratchet is locked in the gear teeth, forbids left-hand revolution.
The beneficial effects of the utility model are:
(1) apparatus structure simple, install and use easyly, can reequip vehicle easily.
(2) electromagnet makes an immediate response for energising, almost not time-delay, therefore device response required time is short, can be fast to mistake the behavior of touching on the brake react.
(3) device is safe and reliable, can effectively avoid tragedy to take place.
(4) device does not rely on sensor and computer control system, can not be interfered.
(5) after the mis-accelerator pressing brake, this device can quickly recover to virgin state, can not have influence on and use next time.
(6) add electro-delay system in the solenoid circuit after, accurately control circuit turnon time, the automobile of convenient various models and load carrying ability carries out the lasting brake in the setting-up time.
(7) even run into some situation, the driver needs the hot refueling door, also can not cause braking automobile, because when hot refueling, the pedal peak acceleration can not surpass 2g, and step on the accelerator not only can influence the vehicle life-span as sudden stop else if, also there is no need.Through investigation, driver's generally reflection is in addition, even if emergent the oiling also can not reach the acceleration/accel of error throttle.
