Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention into
Row detailed description, the description of this part be only it is exemplary and explanatory, should not have any limitation to protection scope of the present invention
Effect.
As shown in Figs. 1-5, specific structure of the invention are as follows: a kind of special vehicle spring-plate type tail-gate electric-control system, Bao Tong
It crosses the main control unit being electrically connected, driver's cabin control button, load person's control button, main electric pushrod 3, tail-gate change-over switch, open
Electric pushrod 4, switch lock change-over switch and angular displacement sensor are shut, the driver's cabin control button, load person's control button are given
Main control unit issues open and close tail-gate 2 and orders, and the main electric pushrod 3 is for driving the opening of tail-gate 2, closing motion to execute, switch
For driving the locking of lock tongue 5, (switch lock electric pushrod 4 stretches out rectifies connection lock tongue 5 to lock electric pushrod 4, pushes itself and 1 side of car body
Lockhole lock), unclamp tail-gate 2 movement execute, tail-gate change-over switch be used for feedback to main control unit tail-gate 2 fully open
Or closed state signal；The switch lock change-over switch is used to believe to the locking or releasing orientation completely of main control unit feedback lock tongue 5
Number；The angular displacement sensor is set to the hinged place of tail-gate 2 Yu car body 1, is used to feed back locating for tail-gate 2 to main control unit
Open angle information.
Preferably, the switch lock electric pushrod 4 include the left-handed opening lock electric pushrod for being relatively arranged on the inside of car body 1,
Right switch lock electric pushrod, the switch lock change-over switch include that left-handed opening lock change-over switch, the right switch lock being accordingly arranged turn
Change switch.
When specifically used, after spring-plate type tail-gate electric-control system powers on, it is constantly in working condition, continually scans for driver's cabin control
The information of key processed and load person room control button differentiates that button priority level executes corresponding operating, and workflow is shown in attached drawing 3.
A, it powers on, system initialization；
B, the key information of driver's button box and load person room button box is continually scanned for, wherein the highest priority that stops key,
Secondary shutdown key, enabling priority is minimum, after determining stopping/shutdown/door opening key state, is transferred to corresponding branched program and executes
Corresponding operating；
C, when executing stopping branched program, stop current all operational orders, reset light signal, then jump to scanning driving
The key information of room control button and load person room control button；
D, when executing enabling branched program, 2 current location of continuous scanning tail-gate: if tail-gate 2 is in a fully open position, stop
Only opening door operation instruct, reset enabling light signal, jump to scanning driver's cabin control button and load person room control button by
Key information；If tail-gate 2 is (being measured by angular displacement sensor according to open angle) in an intermediate position, control master is electronic to be pushed away
Bar 3(uses single armed electric pushrod) continue to release, until tail-gate 2 is in a fully open position, execution tail-gate 2, which is in, to be fully opened
Position；If tail-gate 2 is in fully closed position, main electric pushrod 3 first carries out a movement of pulling back in short-term and reduces friction of unlocking
Resistance, then control switch lock electric pushrod 4 pull lock tongue 5 separated with lockhole (when to make at 2 two sides lock tongue 5 of tail-gate locking by
Dynamic balance, the switch lock electric pushrod 4 include two left and right switch lock electric pushrods being oppositely arranged), switch lock is electronic to be pushed away
Bar 4 triggers switch lock change-over switch, after main control unit senses that lock tongue 5 fully opens, then controls main electric pushrod 2 and releases,
To realize that tail-gate is opened；
E, when executing shutdown branched program, electric current-position curve is shown in Fig. 4, and main electric pushrod 3 i in initial position is maximum, with
Door closing process i be gradually reduced, when spring-plate type tail-gate 2 press 1 doorway of upper body at sealing ring when, into elastic deformation rank
Section, di/ds are positive number, and di/ds is greater than the zero abundant item to work with position feedback information as trigger switch lock electric pushrod 4
Tail-gate 2 is sealed with 4 co-operating of switch lock electric pushrod for part, main electric pushrod 3.
F, tapered squeezing is locked in the closed process of tail-gate 2 (i.e. elastic deformation stage), the pulling force of main electric pushrod 3 and the left and right sides
Power synergy.Angle of taper is α, main 3 elastic deformation phase displacement amount S of electric pushrodMaster cylinderWith left and right lock elastic deformation stage position
Shifting amount SLockRelationship be SMaster cylinder=TanαSLock.If main 3 speed of electric pushrod and switch lock electric pushrod 4 during tail-gate 2 is closed
Speed collaboration is not good enough, and main 3 excessive velocities of electric pushrod can then allow switch lock electric pushrod 4 to be reached home ahead of time to cause motor stifled
Turn, main 3 speed of electric pushrod can then allow switch lock electric pushrod 4 to overload slowly excessively.In Fig. 4 electric current-position curve figure it is visible with
Main electric pushrod 3 is significantly greater than left-handed opening lock electric pushrod electric current in the right switch lock electric pushrod electric current of diagonally opposing corner, so main
Consider main 3 speed of electric pushrod and right lock electric pushrod electric current corresponding relationship:
(1)
By SMaster cylinder=TanαSLockSubstitution formula (1):
(2)
Due to VMaster cylinder(t)=dSMaster cylinder/ dt, formula (2) can be converted to:
(3)
Spring-plate type tail-gate electric-control system PID functional block diagram is shown in Fig. 5, when there is 2 push button signalling X of tail-gate, passes through transmission function GIt is main(S)
Y, feedback signal voltage signal V, current signal I, position signal S, current differential signal di/dt are exported, when di/dt is become by negative
Timing becomes left-right switch lock electric pushrod transmission function G together with position signal SLock(S) input signal, while left and right lock
Current feedback signal ILockBoth it had fed back main transmission function front end or feedback and has locked electric pushrod transmission function front end to left-right switch.
The system-specific passes through the association to main electric pushrod 3 and electric pushrod lock 4 in 2 switching process of spring-plate type tail-gate
With control, realize that automatically lock seals when spring-plate type tail-gate 2 receives, the functions such as automatic unlocking when putting, response rapidly, reliability
Height is grown using receiving the order.
