Detailed description of the invention
As shown in Fig. 1 ~ Fig. 4, the electronic brake device of a kind of vehicle, including master controller 1, motor 2, locking key
Switch 7, brake release press button 8 and frame 3, described motor 2 is fixedly connected in frame 3, described locking key switch 7,
Brake release press button 8 and motor 2 all electrically connect with master controller 1, and its innovative point is: also include disk 4, connecting rod 5, slide
Block 6 and retaining mechanism 10, described disk 4 is fixedly connected on the output shaft 2-1 of motor 2 and has locking slot 4-1, described slide block
6 are slidably connected in frame 3, and the hinged radially outer edge part at disk 4 in described connecting rod 5 one end, the other end is hinged to be slided
On block 6.Described retaining mechanism 10 electrically connects with master controller 1.Described slide block 6 passes through parking bracing wire and is arranged at wheel
Brake connects such that it is able to performs according to the motion of slide block 6 or discharges the brake operating being arranged on the brake at wheel,
Described motor 2 is servomotor.
As shown in Figure 1 and Figure 2, described retaining mechanism 10 includes gas bag 11, electromagnetic gas valve 12, cylinder 13 and latch segment 14, institute
Stating latch segment 14 to be fixedly connected on the piston rod 13-1 of cylinder 13, the air inlet P mouth of described electromagnetic gas valve 12 is with gas bag 11 even
Logical, the mouth A mouth that performs of electromagnetic gas valve 12 connects with the rod chamber of cylinder 13, and electromagnetic gas valve 12 electrically connects with master controller 1.This
Retaining mechanism 10 automaticity is high and can ensure that vehicle retaining mechanism 10 when long-time parking also can be locked.
The air inlet P mouth of described electromagnetic gas valve 12 is provided with Manual gas valve 15, Manual gas valve 15 to the gas passage of gas bag 11
Air inlet P mouth connect with gas bag 11, Manual gas valve 15 perform mouth A mouth connect with the air inlet P mouth of electromagnetic gas valve 12.Just
Under reason condition, the air inlet P mouth of Manual gas valve 15 communicates with performing mouth A mouth, when electromagnetic gas valve 12 or master controller 1 damage, main
Controller 1 can not control the execution mouth A mouth of electromagnetic gas valve 12 when communicating with air, and the most operable Manual gas valve 15 makes it perform
Mouth A communicates with air, the most still can ensure that disk 4 is locked by the latch segment 14 of retaining mechanism 10.
As shown in Figure 5, Figure 6, the locking slot 4-1 of described disk 4 has the first locking face 4-1-1 and the first vertical reference face
4-1-2, the angle of described first locking face 4-1-1 and the first vertical reference face 4-1-2 is α, the locking of described retaining mechanism 10
Block 14 has the second locking face 14-1 and the second vertical reference face 14-2, described second locking face 14-1 and the second vertical reference face
The angle of 14-2 is β, and has α=5 ° and β=5 °.Owing to the locking slot 4-1 of disk 4 and the material of latch segment 14 are steel,
And the Self-locking angle between steel and steel is about 8 °, therefore so arranges and can ensure between the locking slot 4-1 of disk 4 and latch segment 14
Form self-locking, accordingly even when disk 4 also will not be made by moment of face effect latch segment 14 skid off locking slot 4-1, make locking more reliable.
As it is shown in figure 1, the operation principle of the electronic brake device of the vehicle of the present invention is achieved in that due to machine
Frame 3, disk 4, connecting rod 5, slide block 6 form slider-crank mechanism.After pressing locking key switch 7, master controller 1 controls motor 2
Rotate half-turn, disk 4 drivening rod 5 make slide block 6 move right in frame 3, owing to slide block 6 is by parking bracing wire and peace
It is contained in the brake at wheel to connect, thus bracing wire can be driven to make the brake at wheel perform brake operating, when motor 2 rotates
Controlled electromagnetic gas valve 12 dead electricity of retaining mechanism 10 after end by master controller 1, at this moment the execution mouth A mouth of electromagnetic gas valve 12 is with big
Gas phase is led to, and the pressed gas in gas bag 11 cannot pass through electromagnetic gas valve 12 and arrives the rod chamber of cylinder 13, the piston rod of cylinder 13
13-1, under spring force near disk 4, makes the latch segment 14 being fixedly connected on piston rod 13-1 be clamped on disk 4
In locking slot 4-1 thus locking disk 4, make disk 4 not rotate, such slide block 6 can not move along a straight line.Whole mistake
Cheng Buxu passes through manual operation, and therefore automaticity is high.Owing to the piston rod 13-1 of cylinder 13 makes under spring force
Latch segment 14 locks disk 4, locks without by pressed gas, the most when the vehicle is parked between longer, in gas bag 11 without pressure
The locking to disk 4 is still ensured that during strength body.
As in figure 2 it is shown, controlled the electromagnetism gas of retaining mechanism 10 after pressing brake release press button 8 by master controller 1
Valve 12 obtains electric, makes the air inlet P mouth of electromagnetic gas valve 12 communicate with performing mouth A mouth, and the pressed gas in gas bag 11 is through electromagnetism gas
Valve 12 arrives the rod chamber of cylinder 13, and the piston rod 13-1 of cylinder 13 leaves disk 4 under the effect of pressed gas, makes fixing company
The latch segment 14 on stopper rod 13-1 of taking over a job leaves the locking slot 4-1 of disk 4 thus disk 4 is released locking, and disk 4 can turn
Dynamic, rotate half-turn when being controlled motor 2 by master controller 1 after lock release, disk 4 drivening rod 5 make slide block 6 in frame 3
To left movement, owing to slide block 6 is connected with the brake being arranged at wheel by parking bracing wire, thus bracing wire can be driven to make car
Brake release brake operating at wheel.
The present invention is driven disk 4 to rotate by motor 2, by connecting rod 5, the rotation of disk 4 is changed into slide block 6 continuously
Linear motion, is driven bracing wire campaign by slide block 6, drives the parking brake of vehicle, owing to whole drive system is not required to pass through tooth
Wheel, therefore power transmission continuously and wear and tear little, noise is low.The whole drive system of the present invention is not required to use expensive high pressure
Pump, low-lift pump, hydraulic cylinder etc., only need to use disk 4, connecting rod 5 and slide block 6 gyration of motor 2 to be changed continuously
For the straight reciprocating motion of slide block 6 thus be used for controlling bracing wire, drive vehicle parking brake, therefore simple in construction, be manufactured into
This is the lowest.
