Suitable experience of easily riding.Tubular body is to be fixedly connected with armature；Tubular body is to be flexibly connected with coil, and tubular body can be in coil
Inside moves up and down.When in use, when coil no power under the effect of the first spring, vehicle ladder is limited in peak, when riding
When middle speed is down to the minimum setting value for reaching comparator, comparator control coil obtains the electric energy of electric motor car with two wheels power supply, into
And coil generates magnetic force and enforcement vehicle ladder under armature is attracted to fall, and eliminates the action for the frequent support of getting off of middle both feet of riding；Che Qi
When dynamic, coil power is disconnected, vehicle ladder is above carried under the promotion of the first spring, is upwards collected through.
The both sides of connector are equipped with for fixed to the first bolt hole on electric motor car with two wheels, the middle part of connector to be equipped with
One is used for across and limits the first notch of tubulose body position.Vehicle ladder includes a fixing piece 4 for limiting tubulose body position, Gu
The both sides for determining part are equipped with for fixed to the second bolt hole on electric motor car with two wheels, the middle part of connector be equipped with one for across
And limit the second notch of tubulose body position.Vehicle ladder is fixed on two-wheeled with screw by the bolt hole on connector, fixing piece
On the middle part car body of electric vehicle.
Vehicle ladder includes one first pin 5, and the first pin passes through tubular body, and one end of the first spring is fixed on the first pin
On, and then one end of the first spring is fixed on by the first pin on tubular body.To increase the stability of the first spring connection.
The lower part of support leg is equipped at least one rubber wheel.Rubber wheel is arranged in vehicle ladder lower end, reduces impact, keeps vehicle ladder steady
Landing.
The top of support leg is fixed on the lower part of tubular body, and the lower part of support leg sets that there are two stabilizer blades.To increase branch
Stability when spike supports.
The lower part of tubular body is equipped with third notch, and the cross section of the lower part of tubular body is in " ㄇ " shape, and the top of support leg is set
It sets in the lower part of tubular body, the upper hollow of support leg；Vehicle ladder includes a vehicle ladder anticollision protective device, and vehicle ladder anticollision is protected

Both ends be separately fixed at third indentation, there tubular body both sides；The top of support leg is equipped with the through-hole of a strip, the
Three pins pass through through-hole, the both sides of the tubular body of third indentation, there to be equipped with a skewed slot, and skewed slot is connected to third notch, third pin
The both ends both sides that are separately positioned on tubular body skewed slot in；Third pin is arranged in the lower section of the second pin, the second pin
On be fixed with a second spring, one end of second spring is fixed on the second pin, and the other end of second spring is fixed on third
On pin.Support leg can be rotated around the second pin, and third pin can be slided up and down in the through hole of the strip of support leg, normally
Under state, third pin is limited to the top of skewed slot by the pulling force of second spring, when vehicle ladder is by ground shock backward,
Three pins are moved downward by pressure, until abjection, to protect car not tripped, can push down on bolt third with hand later
Pin puts back to third pin in skewed slot, restores normal condition, and then has the function that an anticollision protection.
With comparator 13 using being electrically connected, comparator is used with coil 3 and is electrically connected tachometer generator 12.It tests the speed power generation
Machine is set on axletree of rear wheel, and output voltage is proportional to rotating speed, i.e. rotating speed is higher, and output voltage is higher, tachometer generator
The negative terminal that comparator is given after the filtered adjustment of signal, when comparator is set at less than certain current potential by adjusting anode, output
High potential, to make two field-effect tube 14 be connected, and then coil obtains the power supply 16 of electric motor car with two wheels.That is, wheel
When rotating speed is as low as close to zero, be sent to the voltage of the negative end of comparator with regard to low, comparator will output HIGH voltage, cause field to be imitated
Should pipe conducting, if relay is connected at this time, coil will attract armature movement, vehicle ladder is made to fall, and when vehicle wheel rotation, will
Low-voltage is exported, field-effect tube does not turn on, and coil will not be powered, and vehicle ladder is jacked up by spring, realizes automatic receipts ladder.Field-effect tube
Work except having outside the Pass with the rotating speed of axletree of rear wheel, also to have the actuation of relay, when the power switch for opening electric motor car with two wheels
Afterwards, silicon-controlled not turn on when wheel does not operate also, it will not be led even if comparator output at this time is high voltage fet
It is logical, i.e., when just having opened the not actuated vehicle of power supply, though rotating speed is zero, ladder will not be also fallen, and tachometer generator has after vehicle moves
Output makes silicon-controlled 15 conducting through resistance, and relay is attracted, if making tachometer generator decline again, due to silicon-controlled memory
Function is silicon-controlled to be held on, and relay is attracted always, after only completing the primary power switch for turning off electric motor car with two wheels of riding,
It is silicon-controlled just to turn off, and whether coil motion in ride the logical of field-effect tube will be controlled by comparing device by speed measuring motor
Break to realize.
Although the content of the utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as limitations of the present invention.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the scope of protection of the utility model should be by appended
Claim limit.
