Preferably, by rotatingly connecting two swing arm members 1 arranged along the first direction to the rotating driving member 2, and the projections of the two swing arm members 1 on the first plane form an angle, the folding door leaf 3 connected to the swing arm member 1 is driven to deform, so that the folding door leaf 3 generates a reaction force, thereby offsetting the external force acting on the folding door leaf 3, and thereby improving the anti-push-pull ability of the folding door close to the driving mechanism.

[0029] Optionally, the first direction can be a vertical direction or a horizontal direction, and correspondingly, the first plane can be a horizontal plane and a vertical plane; preferably, the two swing arm members 1 are arranged along the vertical direction, and the two swing arm members 1 are connected to the folding door leaf 3. Since the projections of the two swing arm members 1 on the horizontal plane have an angle, wherein the angle of the angle is greater than 0, the folding door leaf 3 connected to the two swing arm members 1 undergoes a certain degree of deformation under the action of the two swing arm members 1, causing the folding door leaf 3 to generate a reaction force, thereby offsetting the external force acting on the folding door leaf 3, thereby improving the push-pull resistance of the folding door close to the driving mechanism side.

[0030] See also Figure 5 and Figure 6 In some embodiments, the rotary drive member 2 includes a driving shaft 21, and the two swing arm members 1 are connected to the driving shaft 21, and the swing arm member 1 can rotate around the driving shaft 21. That is, the driving shaft 21 is parallel to the first direction, and the two swing arm members 1 are arranged on the driving shaft 21. Preferably, the driving shaft 21 is vertically arranged, one swing arm member 1 is arranged at the upper end of the driving shaft 21, and the other swing arm member 1 is arranged at the lower end of the driving shaft 21; optionally, the upper end of the folding door leaf 3 is connected to the swing arm member 1 arranged at the upper end of the driving shaft 21, and the lower end of the folding door leaf 3 is connected to the swing arm member 1 arranged at the lower end of the driving shaft 21, so that the folding door leaf 3 undergoes a rotation under the action of the two swing arm members 1. A certain degree of deformation, optionally, the deformation is a restorable deformation, optionally, since the two swing arm members 1 are connected to the same driving shaft 21, the two swing arm members 1 can rotate synchronously under the action of the driving shaft 21, so that the folding door leaf 3 maintains the deformation state during the rotation process, and can prevent any one of the swing arm members 1 from rotating alone, causing the folding door leaf 3 to be excessively pulled and damaged, or the projections of the two swing arm members 1 on the horizontal plane to overlap, causing the folding door leaf 3 to return to its original state, and cannot effectively offset the force applied to the folding door leaf 3 by the outside world.

[0031] See also Figure 3 , Figure 5 and Figure 6In some embodiments, the folding door 3 further comprises a transmission shaft 11, through which the swing arm 1 is rotatably connected to the folding door leaf 3.

That is, by rotating any of the swing arm members 1 along the first direction at a preset angle around the driving shaft 21 in advance, and then assembling it with the driving shaft 21, the other swing arm member 1 is directly assembled with the driving shaft 21, so that the projections of the two swing arm members 1 on the first plane have an included angle, wherein the angle of the included angle is equal to the preset angle. For the convenience of description, one of the indoor and outdoor parts is the first side, and the other is the second side, and at least one of the swing arm members 1 is located on the first side when the folding door leaf 3 is in the folded state. During the unfolding process of the folding door leaf 3, the two swing arm members 1 rotate around the driving shaft 21 along the first direction. Preferably, when the folding door leaf 3 is in the unfolded state, one of the swing arm members 1 is parallel to the length direction of the folding door leaf 3, and the other swing arm member 1 rotates to the second side, driving the folding door leaf 3 to the second side direction. Deformation occurs so that the folding door leaf 3 generates a reaction force directed to the first side, so that the thrust acting on the folding door leaf 3 from the first side and the pulling force acting on the folding door leaf 3 from the second side are offset by the reaction force generated by the deformation, and the pulling force acting on the folding door leaf 3 from the first side and the thrust acting on the folding door leaf 3 from the second side are offset by the power transmitted to the folding door leaf 3 by the driving shaft 21 through the swing arm member 1, thereby improving the push-pull resistance of the folding door close to the driving mechanism.

Further, the folding groove 12 is arranged along the length direction of the folding door leaf 3, so the assembly position of the transmission shaft 11 can be further adjusted along the folding groove 12 to optimize the assembly process. Optionally, a stopper 13 is further included, the stopper 13 is assembled in the folding groove 12, and the transmission shaft 11 is connected to the stopper 13. Preferably, the transmission shaft 11 is fixed in the folding groove 12 by the stopper 13, so that when the transmission shaft 11 rotates following the swing arm 1, the transmission shaft 11 can effectively transmit power to the folding door through the folding groove 12 to drive the folding door leaf 3 to rotate. Furthermore, a corresponding stopper can be provided in the folding groove 12 to prevent the transmission shaft 11 from sliding out of the folding groove 12 when the transmission shaft 11 rotates following the swing arm 1.

Optionally, the limiting structure 41 can be a lock buckle, used to limit the side of the folding door leaf 3 away from the rotating drive member 2, thereby improving the push-pull resistance of the folding door leaf 3 away from the rotating drive member 2. At the same time, the side of the folding door leaf 3 close to the rotating drive member 2 is connected to the swing arm member 1, driving the folding door leaf 3 close to the rotating drive member 2 to deform, so that the folding door leaf 3 generates a reaction force for offsetting the thrust acting on the folding door leaf 3 from the first side and the pulling force acting on the folding door leaf 3 from the second side. The pulling force acting on the folding door leaf 3 from the first side and the thrust acting on the folding door leaf 3 from the second side are offset by the power transmitted to the folding door leaf 3 by the driving shaft 21 through the swing arm member 1, thereby improving the push-pull resistance of the folding door close to the driving mechanism.

[0038] Preferably, the limiting structure 41 is in contact with a large surface of one side of the folding door leaf 3. Optionally, the limiting structure 41 may be in a block shape or a long strip shape, etc. Optionally, when the number of the folding door leaf 3 is odd, the long side of the folding door leaf 3 close to the limiting structure 41 rotates from the second side to the first side under the action of the power provided by the driving shaft 21, so the limiting structure 41 is located on the first side and is in contact with the large surface of the folding door leaf 3 close to the first side, providing the folding door leaf 3 with a resistance directed to the second side, so as to offset the pulling force acting on the folding door leaf 3 from the first side and the thrust acting on the folding door leaf 3 from the second side, while the thrust acting on the folding door leaf 3 from the first side and the pulling force acting on the folding door leaf 3 from the second side are offset by the power provided by the driving shaft 21. When the number of the folding door leaves 3 is even, the long side of the folding door leaf 3 near the limiting structure 41 rotates from the first side to the second side under the action of the power provided by the driving shaft 21.
