Description
Technical field
The invention belongs to technical field of automobile parts, relate to a kind of brake gear, be 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 when having met burst, feelings are just nervous, and right crus of diaphragm is not mobile just directly to be stepped down.In recent years, along with the very big improvement of people's material life, Car ownership sharply increased, and " road killer " quantity constantly increases, and in the traffic accident that has led to, having is much in case of emergency, and chaufeur is stepped on phenomenon of taking throttle as brake and produced.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 device and the Patents of a lot of Anti-mis-steppings.But design is complicated mostly, and adopts pressoreceptor, velocity receptor isoelectronic series system, very easily causes interference, causes emergency brake to be lost efficacy.
Summary of the invention
Technical matters to be solved by this invention is that the accelerator instead of brake for present existence prevents that the system architecture principle is complicated, 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 mis-accelerator pressing dead-man's device of the present invention 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 to the rearward end of Das Gaspedal by retractor braid I, the lower end of two-point form taking-up device by retractor braid II be fixed on spacing lower baffle plate above, one end of the following linking springs of spacing lower baffle plate, the other end of spring is fixed, between two-point form taking-up device and 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 solenoid circuit, switch contact I and switch contact II and spacing lower baffle plate are flexibly connected, described solenoid circuit also comprises power supply and electromagnet, both ends of power is electrically connected to switch contact I and electromagnet respectively, electromagnet is electrically connected to switch contact II, the electromagnet top is over against brake pedal.
Preferably, but connecting electronic delay timer also in described solenoid circuit, to realize the lasting brake in setting-up time.Delay timer can be set delay time, so that solenoid circuit kept connecting within 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 by the accelerator pedal position original according to automobile.Das Gaspedal is not when working: the front end is in upwarping state, and rearward end is not carried out rigid fixing, but is fixed on base by spring tension.Therefore the position that during step on the accelerator, the underfooting is stepped on 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 by the brake pedal position original according to automobile.Brake pedal is not when working, and the front end is in upwarping state.Under the prerequisite that does not hinder the normal circumstances brake, the position over against electromagnet on brake pedal can arrange alnico magnets, when mis-accelerator pressing, can increase the suction between electromagnet and 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 of leg-power times, i.e. 300～350N.
Displacement between described spacing overhead gage and 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 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 the usefulness such as volume.
The elastic-restoring force of described spring is to extract 1.5 times of ribbon power out in taking-up device when normal operation, 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.
Apparatus of the present invention design thereby cause the different action of two-point form taking-up device according to normal step on the accelerator and in emergency circumstances mis-accelerator pressing significantly acceleration/accel difference between the two.The two-point form taking-up device is the core parts of apparatus of the present invention, and its upper end is connected with the Das Gaspedal rear end by ribbon, and the free end of the spring that lower end and an end are fixing is connected.For taking-up device, when acceleration/accel can not locking during lower than 0.8g, when acceleration/accel locking immediately during 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 restoring force of internal recovering wind spring, it is motionless that two-point form taking-up device position keeps, thereby this moment, throttle can work.When accelerator instead of brake, because acceleration/accel is large, the general violent acceleration/accel of stepping on surpasses 2g, Das Gaspedal rear end drive 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 lower end spring and move, make solenoid circuit closed, 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.
Winder structure and principle of work:
Inner at taking-up device, 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 connected spring also along the equidirectional rotation, and the spool of rotation is with regard to anti-twisted spring; If reduce throttle, Das Gaspedal can be unclamped ribbon, and spring will tighten up, and the clickwise spool, until make the ribbon tensioning.In case of emergency, with phenomenon of taking throttle as 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.Its core parts are centrifugal clutchs---a kind of fork that increases the weight of that is arranged on spinning reel.When the spool slow circumvolve, fork does not swing, 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 is connected with a pivotable 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 be connected with spool rotation ratchet, and ratchet is locked in the gear teeth, forbids left-hand revolution.
The invention has the beneficial effects as follows:
(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) equipment safety is reliable, can effectively avoid tragedy to occur.
(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 solenoid circuit after, can accurate control circuit turnon time, the automobile of convenient various models and load carrying ability carries out the lasting brake in 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 affect 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.
