Description
Technical field
The present invention relates to new-energy automobile braking equipment fields, more particularly to a kind of contactless automatically controlled foot brake valves.
Background technique
The angle that traditional foot brake valves are depressed by pedal achievees the purpose that brake, the angle that pedal depresses using gas braking
Degree is bigger, and air pressure is bigger, and brake weight is bigger.Although such brake modes can reach brake purpose, very due to air consumption
Greatly, therefore energy consumption is also very big.Such brake modes are suitable for diesel oil or gasoline car etc. using engine as on the vehicle of power source.
On New-energy electric vehicle, since power source is motor, brake can be reached by the way of automatically controlled
Purpose.Automatically controlled foot brake valves are the brake gear being exclusively used on electric car, the angle that automatically controlled foot brake valves are depressed by pedal
Degree triggers internal microswitch respectively, different brake force signals is sent to electronic control unit.The brake weight of use is gradually
Increase.When pedal is depressed more than 10 degree, start pneumatic brake device, use when generally bringing to a halt.
One main bugbear of automatically controlled foot brake valves is how accurately judge the angle that pedal is depressed.Mesh
Preceding detection method is to pass through jogging switches measurement.When pedal is depressed different angles, it is dynamic to trigger different microswitches
Make, and sends operation voltage to electronic control unit.But in actual use, automatically controlled foot brake in the prior art
Valve has the disadvantages that
1, installation and debugging are difficult.There is mobile idle stroke, different microswitch idle stroke angles in microswitch contact
Also different, even same microswitch, due to the limitation of manufacturing process, idle stroke can also have small difference.
Therefore, when using microswitch sense pedal position, need to adjust the installation site of microswitch repeatedly.It installs not position
It is good, then it very likely malfunctions.
2, expensive.There is very high antifatigue want to its contact spring with the microswitch on automatically controlled foot brake valves
It asks, therefore, also very expensive using the microswitch price of such reed, price is generally 10 times of optoelectronic switch 511 or more.
3, there are problems that service life.Since microswitch is contact, although its mechanical life can reach
To millions of times, but since elasticity of spring leaf of the automatically controlled foot brake valves to microswitch is more demanding, in actual use, it is not achieved several
Million times, just malfunction automatically controlled foot brake valves since the fatigue strength of reed can not be restored.
Summary of the invention
The present invention is scarce for automatically controlled foot brake valves installation and debugging are difficult in the prior art, expensive, service life is short etc.
Point provides a kind of contactless automatically controlled foot brake valves.
In order to solve the above technical problems, the present invention is addressed by following technical proposals:

Different location at.The quantity that goes out so as to be acted according to optoelectronic switch obtains different brake force.When the number of inductive switch
Amount is three clock synchronizations, respectively correspond be arranged in when pedal steps on 3 degree, 7 degree, 10 degree at baffle position, stepped on according to pedal
Angle to can be to motor with different brake weights to electronic control unit, and motion stability is conducive to driver
Use.
Further, it is provided with the through slot along universal driving shaft axial direction in fixed plate, is equipped with rod piece in through slot, inductive switch is fixed on
On rod piece, the convenient adjusting to inductive switch position.Valve chamber is equipped in valve body, the cross-sectional area of universal driving shaft both ends part is less than connection
The cross-sectional area in the middle section of moving axis, the middle section of universal driving shaft and the side wall of valve chamber seal, the lower end surface in the middle section of universal driving shaft and valve chamber
Bottom end face between be equipped with spring, depress pedal linkage axis and move down, after release, spring make universal driving shaft restore initial position.
Preferably, further including fixed block, rod piece is optical axis, and fixed block is fixed with induction on the side of baffle and opens
It closes, locking nut one is provided on another side on the other side, fixed block axially opens up through-hole along optical axis, and optical axis passes through logical
Hole, the threaded hole being connected to through-hole is provided on the end face equipped with locking nut one, and locking nut one and threaded hole cooperation contradict and exist
On optical axis.To facilitate the position for adjusting inductive switch, makes to cooperate even closer using being threadedly engaged, prevent in use
The situation of inductive switch appearance activity.Guide rail is provided in fixed plate, fixed block is fallen on guide rail, to make on inductive switch
It is more steady during lower slider, convenient for adjusting.
As a further improvement of the present invention, rod piece is screw rod, and one end of screw rod is provided with bearing block, and the other end is provided with
Adjusting handle is provided with nut block engaged therewith on screw rod, and inductive switch is fixed in nut block.So as to obtain stabilization
Transmission, and inductive switch be not in shake, so as to make braking it is more stable.Screw rod is provided with one end of adjusting handle
It is provided with locking device, locking device includes latch segment and locking nut two, and latch segment is fixed in fixed plate and screw rod
Across latch segment, locking nut two passes through latch segment and contradicts on screw rod.Convenient for the adjusting to inductive switch position, and lock
Device can prevent screw rod from occurring unnecessary rotation when not adjusting.Guide rail is provided in fixed plate, nut block, which is fallen within, to be led
On rail, thus it is more steady during sliding up and down inductive switch, convenient for adjusting.
Using the above technological means, the invention has the following advantages:
The present invention replaces traditional microswitch, light compared with traditional automatically controlled foot brake valves, using optoelectronic switch
