Second elastic component 70 is located in shell 10, and the both ends of the second elastic component 70 are matched with sliding block 23 and mobile promotion 40 respectively
It closes, specifically, the second elastic component 70 is located in sliding block 23 and/or mobile promotion 40, when the both ends of the second elastic component 70 point
When not being fixed on sliding block 23 and mobile putter 40, when mobile putter 40 is mobile towards sliding block 23, the second elastic component 70 is pressed
Contracting.When in one of them that one end of the second elastic component 70 is fixed on sliding block 23 and mobile putter 40 and the other end and sliding block 23 and
When another interval in mobile putter 40 is arranged, after mobile putter 40 or the mobile a distance of sliding block 23, the second elastic component 70
It is compressed.
For example, as shown in figs. 4 and 7, shell 10 has open end 11 and closed end 12, open end 11 has choke
111, the bore of choke 111 is less than the aperture at 10 middle part of shell, and closed end 12 has the central through hole 121 of perforation, sliding block 23
In shell 10.Driving part 30 and one end of crank 21 are pivotably connected, the other end of crank 21 and the one of connecting rod 22
End is pivotably connected, and the other end of connecting rod 22 protrudes into shell 10 from open end 11 and pivotly connects with one end of sliding block 23
It connects, a part of mobile putter 40 is located in shell 10 and the other end of mobile putter 40 passes through central through hole 121 and pedal 2 connects
It connects.Sliding block 23 has convex block 231 close to one end of mobile putter 40, and convex block 231 is set to the periphery wall of sliding block 23.First elastic component
50 are located in shell 10, and the first elastic component 50 can be externally fitted to sliding block 23, and one end of the first elastic component 50 can be with 231 phase of convex block
It supports, the other end of the first elastic component 50 can offset with choke 111.Have between first elastic component 50 and the internal perisporium of shell 10
There is gap, the first elastic component 50 can be compressed or be stretched, and sliding block 23 can be slided relative to shell 10.
Second elastic component 70 is located in shell 10 and between sliding block 23 and mobile putter 40, and the two of the second elastic component 70
End is only against on sliding block 23 and mobile putter 40 respectively.Specifically, first being compressed when mobile putter 40 is mobile towards push rod 23
Push push rod 23 mobile by the second elastic component 70 after second elastic component 70.
Driving part 30 can drive one end of crank 21 to rotate, for example, driving part 30 can drive the one of crank 21
Circular-rotation is done in the end at end, and so as to drive connecting rod 22 to move, connecting rod 22 can move in turn with movable slider 23, shell 10
The direction of motion of sliding block 23 can be limited, sliding block 23 can do back and forth movement along the axis direction of shell 10.Pedal 2 can push away
Dynamic mobile putter 40 moves, and mobile putter 40 may further push sliding block 23 to do round-trip fortune along the axis direction of shell 10
Dynamic, sliding block 23 can compress the first elastic component 50, and mobile putter 40 and cooperation the second elastic component 70 of compression of sliding block 23 in turn.It moves

In order to improve the effective brake of automobile, the pedal sense simulator 1 of the embodiment of the present invention is with brake-by-wire instead of biography
It unites hydraulic or Pneumatic braking system pedal structure.Brake-by-wire not only has fast response time, control precision height, braking ability
Well, it the features such as flexible arrangement, but also can be integrated with the electronic control unit 3 of vehicle, provide flexibility and changeability for vehicle
Brake force.In the related technology, brake pedal and wheel cylinder are directly connected to by mechanical organs such as fluid pressure lines, and driver steps on
Lower brake pedal makes automobile obtain corresponding brake force.On-line Control is moved in system, due to eliminating brake pedal and brake
Between hydraulic or mechanical connection so that feedback is to the braking reaction on brake pedal when driver can not directly perceive braking
Power causes the brake feel of pedal 2 bad, provides well for driver so as to avoid the brake feel of Conventional braking systems
Brake pedal feel.Brake feel be it is a kind of it is comprehensive feel, it includes the vehicle system that pedal brake feeling, driver experience
The factors such as dynamic deceleration, brake noise acoustically and visual vehicle deceleration, wherein pedal brake feel be
Most important component part.Pedal brake of the invention feels that feedback obtains removing intermediate variable after driver steps on pedal 2
(such as hydraulic, air pressure), with the pedal sense in purely mechanic mechanism analog driving conditions, to improve the sound of motor vehicle braking system
Answer speed and mechanical performance.
The working principle of pedal sense simulator 1 are as follows: the design object of pedal force is by elastic component and certain control method
Pedal simulated behavior is come out.Since elastic component has a linear characteristic mostly, and pedal characteristic sometimes for be it is nonlinear,
Therefore the method simulation pedal reaction force that the pedal sense simulator 1 of the embodiment of the present invention is combined using elastic component with motor 31, i.e.,
Using the elastic force of elastic component and the driving force of motor 31 come comprehensive simulation pedal force.The first elastic component 50 in the embodiment of the present invention
It is series design with the second elastic component 70.The driving force of motor 31 acts directly on mobile putter 40 by slider-crank mechanism 20
On, thus 2 rigidity of pedal of pedal sense simulator 1 be it is adjustable, the first elastic component 50 and the second elastic component 70 provide basis
Pedal reaction force guarantees that braking system works " brake feel " of real-time pedal 2, motor 31, the first elastic component 50 and the second elasticity
Part 70 provides target pedal force, the remainder between compensated foundation pedal force and target pedal force together.First elastic component 50
And the second relationship between elastic component 70 and motor 31 is, when motor 31, input gear 32, output gear 33, crank block machine
Structure 20 etc. breaks down, and when can not move, the first elastic component 50 and the second elastic component 70 still can be moved, and passes through detection device
4 can perceive the movement of pedal 2, continue to implement effective brake, keep normal braking function.
In vehicle operation, when driver needs to be implemented braking function, driver steps on pedal 2, mobile putter 40
(left side as shown in Figure 1) moves to the left, compresses the second elastic component 70, completes initial pedal travel S1, during S1, pedal
The braking stiffness for feeling simulator 1 is K1.Then, mobile putter 40 continues to move to the left (left side as shown in Figure 1), pushes sliding block 23
(left side as shown in Figure 1) first elastic component of motion compresses 50 to the left, completes main pedal travel S2, pedal sense mould during S2
The rigidity of quasi- device 1 is K2.Due to the compressive deformation of the second elastic component 70 and the first elastic component 50, cause mobile putter 40 by anti-
To active force, motor 31 passes through the mating reaction of input gear 32 and output gear 33, and increment drives crank block machine after slowing down
Structure 20 provides power-assisted to mobile putter 40, reduces the opposition that mobile putter 40 is subject to, obtains mobile putter 40 properly
Opposition, which is brake pedal force, to simulate the target value of pedal force and pedal travel.When
When driver's pushes pedals feel partially soft or partially hard, the movement of motor 31, Jin Ergai can be changed by electronic control unit 3
The stress for becoming mobile putter 40 makes driver obtain more good pedal sense.When the first elastic component 50 or motor 31 are because of certain original
Because breaking down, when can not move, the second elastic component 70 still can be moved, and can detecte pedal travel by detection device 4,
Continue to implement braking, keeps braking function.
