[0030] It also includes a right side guide rail 7 disposed on the right side of the door body 1, the right side guide wheel 4 rollingly cooperates on the right side guide rail 7, and the upper section of the right side guide rail 7 is bent toward the inner side of the door body 1 and extends to form a right side extension section 70 opposite to the left side extension section 60;

[0031] It also includes a synchronous gear 81 arranged on the inner side of the door body 1, an auxiliary wheel 82 arranged on the outer side of the door body 1, and a brake motor 83 for driving the synchronous gear 81 to rotate; the axis connecting the synchronous gear 81 and the auxiliary wheel 82 is normal to the door body 1, the synchronous gear 81 is meshed with the synchronous belt 5 through the transverse rack 51, and the wheel edge of the auxiliary wheel 82 abuts against the door body 1 to form a rolling fit.

[0032] In the above embodiment, when the door body 1 is opened, the brake motor 83 drives the door body 1 to move along the left guide rail 6 and the right guide rail 7 with the cooperation of the synchronous gear 81 and the synchronous belt 5, and then the door body 1 turns and moves sideways through the left extension section 60 and the right extension section 70, which significantly reduces the lateral depth space occupied by the door body 1.

[0033] In particular, the left extension section 60 and the right extension section 70 are not limited to horizontal extension, but can also be designed as special-shaped curved structures that match the architectural shape. They can still provide guidance and spatial support for the turning of the door body 1, and can also achieve the effect of reducing the side depth space occupied by the door body 1.

[0038] In another preferred embodiment, Figure 6 , Figure 7 and Figure 8 As shown, the curtain piece 2 is provided with a head 20 at both ends, one end of the head 20 is fixedly connected to the curtain piece 2, and the other end of the head 20 forms a mounting opening 21; the synchronous belt 5 is connected to the outer wall of the head 20, and the left guide wheel 3 and the right guide wheel 4 respectively install the wheel axle in the mounting opening 21. The significance of this arrangement is that the curtain piece 2 is usually made of profiles, and the head 20 can seal the cavity inside the profile, and it is also convenient to assemble the synchronous belt 5, the left guide wheel 3 and the right guide wheel 4.

[0039] Furthermore, the head 20 is provided with screws that penetrate into the installation opening from the outer wall, and the axle of the left guide wheel is fixed to the head by the screws, and the axle of the right guide wheel and the synchronous belt are also fixed to the head by screws, thereby simplifying the assembly structure.
