Embodiment
Come the further details of explanation present invention, but protection scope of the present invention with specific embodiment below in conjunction with the accompanying drawings
It is not limited to this.
As Figure 1-5, the present invention is a kind of electronic biparting inner swing door system, and the system includes door-plate, is arranged on door-plate
The pallet 4 of top, the drive device and transmission mechanism for driving door-plate folding, above-mentioned drive device include being arranged on pallet 4
Push rod tailstock 7, motor 111 and electric pushrod 11, transmission mechanism includes support 3, master rocker 10, output shaft, connecting rod and swing arm；
Electric pushrod 11 therein is fixed on pallet 4 by tailstock 7, and pallet 4 is fixed on vehicle body doorframe 26.Electric pushrod 11 passes through
Master connecting-rod 5 is linked together with master rocker 10, and master rocker 10 is fixed on output shaft 9 together with pivoted arm 15, and output shaft 9 passes through V
Shape support 3 is fixed on pallet 4.The middle part of pivoted arm 15 is output shaft 9, and both ends are connected with left connecting rod 2 with right connecting rod 6 respectively,
The other end of left connecting rod 2 is connected with the left rocking arm 1 on door-hinge, and the other end of right connecting rod 6 is connected with right rocking arm 8.Shake on a door-hinge left side
Arm 1 and the right rocking arm 8 of door-hinge are respectively fitted on left-hand door axle 18 and right door-hinge 19.Left-hand door axle 18 is connected with left door plate 20, right door-hinge 19
It is connected with right door plate 21.The left axis of guide 24 and the right axis of guide 25 are separately fixed in left door plate 20 and right door plate 21.Left chute 16
It is fixed on right rail 17 on pallet 4, the left axis of guide 24 and the right axis of guide 25 can do straight line in left chute 16 and right rail 17
Sliding motion.Drive device is provided with electromagnetic brake 12, and described electromagnetic brake 12 is connected with the main shaft of motor 111, and logical
Cross bracing wire 13 to be connected in solution lock cylinder 14, solution lock cylinder 14 is arranged on electric pushrod, and hand is additionally provided with electromagnetic brake 12
Dynamic reseting handle 121, for releasing brake sticking brake of the electromagnetic brake to motor.
Inner swing door open and close door process is：When pressing door open button, electromagnetic brake 12 it is electric after unclamp to electric pushrod
11 brake sticking brake, the motor 111 of electric pushrod 11 are rotated, and rotary motion campaign is converted into connecting rod 5 by electric pushrod
Linear motion, master rocker 10 is promoted to rotate, master rocker 10 drives swing arm 15 to rotate, so as to drive left connecting rod 2 and right connecting rod 6 to move
Dynamic, left connecting rod 2 and right connecting rod 6 drive left rocking arm 1 and right rocking arm 8 to rotate, so as to drive left-hand door axle 18 and right door-hinge 19 to rotate, band
Dynamic left fan door 20 and right wing door 21 perform the action of open and close door.
After passenger doors are closed, motor 111 stops operating, and electromagnetic brake 12 powers off, because electromagnetic brake 12 is disconnected
Electric braking type, therefore can be by the output shaft brake sticking brake of motor 111, so as to ensure that passenger doors persistently remain turned-off shape after powering off
State.Simultaneously in vehicle operation, motor 111 and electromagnetic brake 12 are in off-position, so as to reduce vehicle energy consumption.
When car door all powers off suddenly, because electromagnetic brake 12 is power-off brake sticking brake, therefore rear brake is powered off
The output shaft band-type brake of motor 111, passenger doors can will not also be automatically opened up, avoid passenger and throw away car by 12 in the event of a power failure
Potential risk, improve the security of vehicle.
As shown in Fig. 2 because left rocking arm 1 and right rocking arm 8 are different with horizontal angle, left connecting rod 2 and the length of right connecting rod 6
Degree is different, therefore when opening the door, the angular speed that left fan door-plate 20 rotates will be faster than right wing door-plate 21, so as to realize two fan door-plates it
Between speed difference, realize it is left fan door-plate first open, opened after right wing door-plate, avoid left sealing joint strip 22 and right sealing joint strip 23 from existing
The problem of interfering during switch gate.
As shown in figure 5, open passenger doors under emergency rating：Under emergency rating, when passenger rotates within the interior or exterior of the vehicle
During pneumatic emergency button, the solution lock cylinder 14 on electric pushrod 11 is died, and the back-moving spring solved inside lock cylinder 14 will
Cylinder piston rod retracts, and drives bracing wire 13 to move, and bracing wire 13 drives the hand-reset handle 121 of electromagnetic brake 12 to rotate, from
And brake sticking brake of the electromagnetic brake 12 to motor 111 is released, freely rotating for motor is realized, so as to realize manual open and close door
Function.
It is noted that above-described embodiment is general to the illustrative and not limiting of technical solution of the present invention, art
The equivalent substitution of logical technical staff or the other modifications made according to prior art, as long as not exceeding technical solution of the present invention
Thinking and scope, it should be included within interest field of the presently claimed invention.
