One end of the pedal input structure of system, including pedal input lever and ball seat, the pedal input lever is inserted in place in power-assisted
In ball seat inside the First piston bar of the series brake master cylinder of system, the pedal input lever extend into ball seat one end
One end in ball-and-socket is connecting ball head, and one end of the ball seat is evenly distributed with several slot segmentations for side wall point along side wall
It is cut into the ear portion that several insides are cambered surface, passes through envelope section transitions outstanding, institute between the ear portion and ball-and-socket
One end inner hole bottom for the First piston bar stated is disposed with ball seat mounting hole, and the ball seat slides in ball seat mounting hole.
As a kind of supplement to technical solution described in the utility model, it is disposed in the middle part of the pedal input lever
For fixing the groove of dustband.
Further, the other end of the pedal input lever is disposed with the pedal bulb for being connected with brake pedal.
Further, positioned at the one circle ball seat limit of one end of ball seat mounting hole arrangement in the inner hole of the First piston bar
The side of protruding portion, the ball seat limiting projection is disposed with conical transition portion.
The utility model has the advantages that the utility model relates to a kind of pedal input structure of integrated electrical control braking force aid system, structure
Simply, small in size, it is flexible for installation, it is convenient for disassembly and assembly using unique ball socket structure, pedal input lever can also be effectively prevent sliding
It is de-.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in figures 1 to 6, the embodiments of the present invention is related to a kind of pedal of integrated electrical control braking force aid system
Input structure, including pedal input lever 3 and ball seat 2, one end of the pedal input lever 3 are inserted in place the string in force aid system
In ball seat 2 inside the First piston bar 1 of connection formula master cylinder, the pedal input lever 3 extend into the ball-and-socket of 2 one end of ball seat
One end in 22 is connecting ball head 31, and one end of the ball seat 2 is evenly distributed with several slot segmentations 21 for side along side wall
It is the ear portion 24 of cambered surface that wall, which is divided into several insides, passes through envelope portion outstanding between the ear portion 24 and ball-and-socket 22
Divide 23 transition, one end inner hole bottom of the First piston bar 1 is disposed with ball seat mounting hole 11, and the ball seat 2 is in ball seat
Sliding in mounting hole 11.
The middle part of the pedal input lever 3 is disposed with the groove 32 for fixing dustband, the installation of convenient dust-proofing circle.
The other end of the pedal input lever 3 is disposed with the pedal bulb 33 for being connected with brake pedal, pedal ball
The length of first 33 shape and pedal input lever 3 can require to be modified according to the different of different automobile types.
Positioned at one circle ball seat limiting projection of one end of ball seat mounting hole 11 arrangement in the inner hole of the First piston bar 1
13, the side of the ball seat limiting projection 13 is disposed with conical transition portion 14.
As an embodiment of the present invention, ball seat 2 shows three kinds of different shapes in different installation processes
State；Connecting ball head 31 is pressed into during ball-and-socket 22, and ear portion 24 can stir outward, and slot segmentation 21 broadens；Connecting ball head 31 is pressed into
After ball-and-socket 22, ear portion 24 restores to arrive original position originally.
Ball seat 2 and the First piston bar 1 of series brake master cylinder are attached, and can bear certain pulling-out force；Ball seat 2
After the completion of connecting with pedal input lever 3, it is co-pressed into First piston bar 1；Due to the ball seat limiting projection 13 of First piston bar 1
Internal diameter is less than the outer diameter in ear portion 24, and during ball seat 2 is pressed into First piston bar 1, therefore the slot segmentation 21 of ball seat 2 can become
It is narrow, make 24 extrusion of ear portion and embrace pedal input lever 3, and finally makes ear portion 24 can be by ball seat limiting projection
13；After ball seat limiting projection 13, ear portion 24 restores to the original state；At this time in the end in ear portion 24 and First piston bar 1
The fitting of 13 end face of ball seat limiting projection, prevents from；The limitation of connecting ball head 31 and the envelope part 23 because of ball seat 2, also not
It can deviate from, and certain pulling-out force can be born.Particularly, the conical transition portion 14 of First piston bar 1 is set as preventing ball seat 2 from existing
It is scratched when being pressed into First piston bar 1 and the cone cell of slow transition.
The utility model structure is simple, small in size, flexible for installation, convenient for disassembly and assembly using unique ball socket structure, can be with
It effectively prevent pedal input lever to slip.
