The technical solution adopted by the present invention to solve the technical problems is：A kind of integrated electrical control braking force aid system is provided
Pedal input structure, including pedal input lever and ball seat, one end of the pedal input lever be inserted in place in force aid system
Series brake master cylinder First piston bar inside ball seat in, the pedal input lever extend into the ball-and-socket of ball seat one end
Interior one end is connecting ball head, and one end of the ball seat is evenly distributed with several slot segmentations along side wall and is divided into side wall
Several insides are the ear portion of cambered surface, described by envelope section transitions outstanding between the ear portion and ball-and-socket
One end inner hole bottom of First piston bar is disposed with ball seat mounting hole, and the ball seat slides in ball seat mounting hole.
As a supplement to the technical solution of the present invention, it is disposed with and is used in the middle part of the pedal input lever
The groove of fixed 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.
Beneficial effect：The present invention relates to a kind of pedal input structures of integrated electrical control braking force aid system, and structure is simple,
It is 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 to slip.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in figures 1 to 6, embodiments of the present invention are related to a kind of pedal input of integrated electrical control braking force aid system
Structure, including pedal input lever 3 and ball seat 2, one end of the pedal input lever 3 are inserted in place the tandem in force aid system
In ball seat 2 inside the First piston bar 1 of master cylinder, the pedal input lever 3 is extend into the ball-and-socket 22 of 2 one end of ball seat
One end be connecting ball head 31, one end of the ball seat 2 is evenly distributed with several slot segmentations 21 for side wall point along side wall
It is cut into the ear portion 24 that several insides are cambered surface, passes through envelope part 23 outstanding between the ear portion 24 and ball-and-socket 22
Transition, one end inner hole bottom of the First piston bar 1 are disposed with ball seat mounting hole 11, and the ball seat 2 is installed in ball seat
Sliding in 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 a kind of embodiment of the invention, ball seat 2 shows three kinds of different states in different installation processes；Even
It receives during first 31 indentation ball-and-socket 22, ear portion 24 can stir outward, and slot segmentation 21 broadens；Connecting ball head 31 is pressed into ball-and-socket 22
Afterwards, 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 configuration of the present invention is simple, it is small in size, it is flexible for installation, it is convenient for disassembly and assembly using unique ball socket structure, it can also be effectively
Prevent pedal input lever from slipping.
