The door carrying frame 1 is connected with a door body, and the door carrying frame 1 drives the door body to perform left and right opening and closing actions relative to the door base frame 2 under the action of the power device. The locking device is usually arranged on the door base frame 2, when the door body needs to be opened, the locking of the door carrying frame 1 is unlocked, and after the door body is closed, the positioning locking of the door carrying frame 1 is realized.
The door base frame 2 includes a base beam 201 and hangers 202 connected to both ends of the base beam 201, and guide holes 203 are formed in the two hangers 202 in the front-rear direction.
The power device of the vehicle door comprises a driving mechanism 3, a guide member 4, a guide wheel 5, a driving wheel 6, a force increasing member 7 and a support beam 8.

The driving wheel 6 is fixedly connected to the bottom of the mover 32, and is movable left and right along with the mover 32.
The fixed guide 4 that is provided with in the below of base beam 201 in door bed frame 2, this guide 4 downwardly opening is provided with the guide slot that leads door carrying frame 1 and carry out the switching action, and the guide slot includes straight straightly the straightly and the curved line section of bending connection in straightly the one end. The curved section in this embodiment curves forward from the end of the straight section.
The two ends of the supporting beam 8 are connected in the guide holes 203 of the two hangers 202 through the rollers 82, and the supporting beam 8 can move back and forth relative to the door base frame 2 through the rollers 82 under the guide of the guide holes 203. A guide rail 81 extending in the left-right direction is provided on the support beam 8 in the axial direction of the support beam 8, and a guide block 11 which can be placed in the guide rail 81 is connected to the door carrying frame 1. That is, the door carrying frame 1 is supported on the support beam 8, and can provide support and guide in the left-right direction for the left-right movement of the door carrying frame 1 under the interaction of the guide rail 81 and the guide block 11. The support beam 8 is also able to move back and forth relative to the door chassis 2 and thus is able to support the door carrier 1 back and forth relative to the door chassis 2.
The guide wheel 5 is arranged on the upper surface of the door carrier 1 and the guide wheel 5 is placed in a guide slot of the guide 4, providing guidance for the door opening and closing action as well as the plugging action of the door carrier 1 by cooperation of the guide wheel 5 and the guide slot.
The force increasing piece 7 is fixedly connected to the upper surface of the portal frame 1, the force increasing piece 7 is provided with an accommodating area 71 which is in an L shape and is in smooth transition, the accommodating area 71 is continuously and curvedly arranged from front to back and towards the door closing direction, the stroke of the accommodating area 71 is matched with the stroke of a curve section in a guide groove, the accommodating area 71 can be arranged into a groove or a hole according to needs, the driving wheel 6 is arranged in the accommodating area 71, and when the rotor 32 drives the driving wheel 6 to move, the driving wheel 6 drives the force increasing piece 7 to move, and then the portal frame 1 is driven to perform opening and closing actions.
For the sake of convenience of the following description, the left-right direction is defined as the lateral direction, and the front-rear direction is defined as the longitudinal direction.
The specific working process of the power device of the vehicle door comprises the following steps: when the door body is in a closed state, the driving wheel 6 is positioned at the outermost end of the transverse part of the accommodating area 71 in the force increasing piece 7, and the guide wheel 5 is also positioned at the outermost end of the guide groove in the guide piece 4. When the door body needs to be opened, the linear motor works, so that the mover 32 moves transversely in the door opening direction. Thus, the mover 32 drives the driving wheel 6 to move a distance towards the inner end of the transverse portion of the accommodating area 71 until the driving wheel pushes against the inner wall of the accommodating area 71 of the force increasing member 7. With the further movement of the mover 32, the driving wheel 6 will generate a force on the force increasing member 7 in the door opening direction, and the force is applied to the door carrying frame 1, and the guide wheels 5 on the door carrying frame 1 will move the door carrying frame 1 as a whole forward under the action of the guide grooves on the guide member 4, so as to drive the force increasing member 7 and the supporting beam 8 as a whole forward relative to the door base frame 2. In the process that the boosting part 7 moves forwards, the driving wheel 6 cannot move in the front-back direction, and then the driving wheel 6 can slide into the longitudinal part of the accommodating area 71 in the process that the door carrying frame 1 performs the plugging action, when the driving wheel 6 reaches the outermost end of the longitudinal part of the accommodating area 71, the guide wheel 5 just enters the straight line section from the curve section of the guide groove, and then the door carrying frame 1 is driven to perform the opening action through the driving action of the driving wheel 6 along with the action of the driving mechanism 3. In this process, the movement distance of the driving mechanism 3 driving the driving wheel 6 to move in the transverse direction includes the distance of the transverse movement of the door carrying frame 1 and the distance of the transverse part of the accommodating area 71, that is, the movement distance of the driving mechanism 3 driving the driving wheel 6 in the transverse direction is greater than the movement distance of the door carrying frame 1. And the carrying frame 1 and the force-increasing plate move by the same distance in the longitudinal direction. By utilizing the virtual work principle, the acting force exerted by the driving mechanism 3 is smaller than the acting force which can be actually obtained by the door carrying frame 1, namely, the effect of increasing the force transmitted from the driving wheel 6 to the boosting part 7 is realized.
The closing process of the door body is opposite to the above process. On the premise that the driving mechanism 3 does not work, if the door opening transverse door opening acting force acting on the door carrying frame 1 exists, the driving wheel 6 keeps the position unchanged, the door carrying frame 1 is limited to move longitudinally, and the locking effect is achieved.
