The operating principle of the sliding plug door assembly in the embodiment is as follows:
when the door plates 11 on two sides in the sliding plug door assembly need to be closed, the driving end of the driving cylinder 9 pulls the sliding sleeve 5 on one side, the sliding sleeves 5 on two sides respectively slide along the sliding rod 3 relatively under the action of the drawing wire 6, and then the guide wheel 8 follows the sliding sleeve 5 and moves into the guide groove 102 under the guiding action of the guide groove 102. Meanwhile, the driving cylinder 9 has an acting force opposite to the sliding sleeve 5 on the pull rod 4, and drives the pull rod 4 to push the two-side connecting shaft driving mechanism 2 and the sliding rod 3 to do linear movement close to the inner side of the vehicle, and the specific process is as follows:
the driving cylinder 9 drives the rotation connection point between the pull rod 4 and the driving arm 202 in the two-side connecting shaft driving mechanism 2 to be close to the rotation connection point between the connecting arm 203 and the sliding support 201, so that the driving arm 202 rotates clockwise around the rotation connection point between the driving arm 202 and the base 1, the connecting arm 203 rotates anticlockwise around the rotation connection point between the connecting arm 203 and the driving arm 202, and the sliding support 201 in the one-side connecting shaft driving mechanism 2 is forced to move linearly towards the inside of the vehicle relative to the support guide groove 101 under the dual guiding action of the guide wheel 14 and the support guide groove 101 as well as the sliding roller 12 and the sliding rail 13, and the sliding support 201 in the other-side connecting shaft driving mechanism 2 moves linearly relative to the support guide groove 101 under; the guide wheel 8 and the door carrying frame 10 arranged on the sliding sleeve 5 move along the sliding rod 3 together with the sliding sleeve 5, and the sliding rod 3 and the pull rod 4 are connected with the sliding supports 201 on the two sides, so when the sliding supports 201 move to the extreme positions of the support guide grooves 101 close to the inner side of the vehicle, the sliding rod 3, the pull rod 4, the driving cylinder 9, the sliding sleeve 5, the guide wheel 8 and the door carrying frame 10 on the sliding sleeve and the door panels 11 on the two sides fixed below the door carrying frame 10 all move linearly towards the inner side of the vehicle along with the sliding supports 201, and under the double action, the door panels 11 on the two sides are closed.
In the above process, when the guide wheel 14 of the sliding bracket 201 moves to the extreme position where the bracket guide groove 101 is close to the vehicle inner side, the connecting shaft driving mechanisms 2 on both sides are in the self-locking state, at this time, four points of the rotation connection point of the pull rod 4 and the driving arm 202, the rotation connection point of the driving arm 202 and the base 1, the rotation connection point of the driving arm 202 and the connecting arm 203, and the rotation connection point of the connecting arm 203 and the sliding bracket 201 are all located on the same straight line, and the limiting block 204 just supports against one side of the rotation connection point of the pull rod 4 and the driving arm 202, even if the external force of the driving cylinder 9 on the pull rod 4 is released, the four points cannot be easily separated from the straight line because of being located on the same straight line, so that when the door panel 11 is closed, the pulling force of the driving cylinder 9 can, the guide wheel 8 can be effectively prevented from sliding out of the guide groove 102, an effective vehicle door self-locking effect is achieved, power is saved, and the automobile door self-locking device is green and environment-friendly.
When the door plates 11 on two sides in the sliding plug door assembly need to be opened, the driving end of the driving cylinder 9 pushes the sliding sleeve 5 on one side, the sliding sleeves 5 on two sides respectively slide along the sliding rod 3 in opposite directions under the action of the wire drawing 6 and the wire drawing wheel 7, and then the guide wheel 8 follows the sliding sleeve 5 and moves out of the guide groove 102 under the guiding action of the guide groove 102. Meanwhile, the driving cylinder 9 also has an acting force opposite to the sliding sleeve 5 connected with the guide wheel 8 on the pull rod 4, and drives the pull rod 4 to push the two-side connecting shaft driving mechanism 2 and the sliding rod 3 to move linearly towards the inner side of the vehicle, and the specific process is as follows:
the driving cylinder 9 drives the rotation connection point between the pull rod 4 and the driving arm 202 in the two-side connecting shaft driving mechanism 2 to be far away from the rotation connection point between the connecting arm 203 and the sliding support 201, so that the driving arm 202 rotates anticlockwise around the rotation connection point between the driving arm 202 and the base 1, the connecting arm 203 rotates clockwise around the rotation connection point between the connecting arm 203 and the driving arm 202, and the sliding support 201 in the one-side connecting shaft driving mechanism 2 is forced to move linearly towards the outside of the vehicle relative to the support guide groove 101 under the dual guiding action of the guide wheel 14 and the support guide groove 101 as well as the sliding roller 12 and the sliding rail 13, and the sliding support 201 in the other-side connecting shaft driving mechanism 2 moves linearly towards the outside of the vehicle; when the sliding support 201 moves to the extreme position of the support guide groove 101 far away from the inner side of the vehicle, the sliding rod 3, the pull rod 4, the driving cylinder 9, the sliding sleeve 5, the guide wheel 8 and the door carrying frame 10 thereon, and the door panels 11 fixed at two sides below the door carrying frame 10 all move linearly along with the sliding support 201 to the far away from the inner side of the vehicle, and under the double actions, the door panels 11 at two sides are opened.
Because the driving cylinder 9 in the sliding plug door assembly is fixed on the pull rod 4 and the driving end thereof is fixedly connected with the sliding sleeve 5, when the driving cylinder 9 pulls or pushes one side of the sliding sleeve 5 to slide the two side sliding sleeves 5 relatively or oppositely along the sliding rod 3 to close or open the door panel 11, the driving cylinder 9 will also reciprocate relative to the base 1 along with the sliding brackets 201 in the two side connecting shaft driving mechanisms 2, so that the driving cylinder 9 pulls or pushes the sliding sleeve 5 to move, and simultaneously, according to the interaction of forces, the driving cylinder 9 will pull or push the pull rod 4 to move in opposite directions, so that when the two side door panels 11 are closed or opened, the force applied by the driving cylinder 9 to the sliding sleeve 5 (i.e. the force applied by the driving cylinder 9 to the guide wheel 8) will not be only applied to the guide wheel 8, but also be dispersed to the two side connecting shaft driving mechanisms 2, and because this stopper sliding door assembly's structure sets up, the even axle actuating mechanism 2 of both sides, the guide pulley 8 in the middle of, slide bar 3, pull rod 4 and drive actuating cylinder 9 homoenergetic do reciprocating motion relatively base 1 simultaneously for the power that disperses on guide pulley 8 and the even axle actuating mechanism 2 of both sides can keep balanced at three points, thereby has guaranteed that this stopper sliding door can be very steady when closing or opening.
