Through the hollow arrangement structure with a gap between the guide wheel connecting rod 325 and the supporting part 3142 and the arrangement structure with a cavity arranged at the side edge of the supporting part 3142, hidden wiring can be better performed. It should be further noted that the supporting portion 3142 is disposed on the connecting arm 324, so as to better support the sliding connection end 322, and the supporting portion 3142 is provided with the supporting shaft 3143 to be rotatably connected with the guide wheel connecting rod 325, so that the guide wheel connecting rod 325 can rotate around the supporting shaft 3143 in the horizontal direction, so as to better automatically adjust the lateral force of the door body, and make the force applied more uniform.

It should be noted that the guide wheel 323 in this embodiment may be replaced by a sliding block, and by providing a guide wheel or a sliding block, the friction force when contacting with the door body may be reduced, and the stability of the door body in the motion process may be improved.

Referring to fig. 9 and 9B, the fixed connection end 321 is connected to the first door 100, and the sliding connection end 322 is connected to the second door 200. The sliding connection end 322 can be slidably connected to the top of the second door body 200, for example, slidably connected to the sliding rod 210 on the top of the second door body 200. The slide bar 210 at the top of the second door body 200 may be provided with an open cavity 412, and the guide wheel 323 extends from the opening and is locked in the slide cavity 412 of the slide bar in the second door body 200 to slide, so as to realize a sliding connection with the second door body 200, so that the first door body 100 and the second door body 200 are connected with each other and can slide relatively. The cavity 412 may include two sidewalls 4121 and 4122, and the guide wheel 323 may be attached to the sidewalls 4121 and 4122 of the cavity 412 to roll, so as to provide a lateral guiding function for the second door 200, reduce the friction force when the guide wheel 323 contacts the door, and improve the stability of the door in the moving process.

Taking the example of providing two guide wheels 323 at the sliding connection end 322, the two guide wheels 323 are connected by a guide wheel link 325 and located at two ends of the guide wheel link 325, respectively, and the middle part of the guide wheel link 325 is rotatably connected to the connection arm 324, so that the guide wheel link 325 can rotate around the connection arm 324 in the lateral direction, and further, the two guide wheels 323 located at two ends of the guide wheel link 325 are always in sliding contact with the side wall 4121 or 4122 of the cavity 412, i.e., the guide wheels 323 are confined between the two side walls 4121 and 4122 and roll with one of the side walls. Therefore, when the second door 200 is operated, the lateral force of the second door 200 can be automatically adjusted, so that the first door 100 can support the second door 200 more stably in a sliding manner in the lateral direction, the relative movement between the doors is more stable, and the problem of blocking is not easy to occur.

In this embodiment, the cavity 412 may be formed along the length direction of the door body slide rod 210, and the structure of the cavity 412 is matched with the shape of the slide connection end 322. When the sliding connecting piece 319 is installed, the fixed connecting end 321 may be fixedly connected to the first door body 100, then the guide wheel 323 of the sliding connecting end 322 is aligned with the opening of the cavity 412 of the second door body 200 and slowly clamped, after the clamping, the sliding connecting end 322 is accommodated in the cavity 412, the guide wheel 323 abuts against the side walls 4121 and 4122 of the cavity 412, and the connecting arm 324 extends outward from the opening of the cavity 412 and is connected to the fixed connecting end 321 on the first door body 100. Due to the structural arrangement, the sliding connection end 322 can be slidably locked in the cavity 412, so that the sliding connection between the first door body 100 and the second door body 200 is realized, and the hidden installation of the sliding connection end 322 in the cavity at the top of the door body is also realized.

It should be noted that the connection positions of the fixed connection end 321 and the sliding connection end 322 with the door bodies may also be the bottoms of the door bodies, for example, the sliding connection end 322 is connected with the bottom of one door body, the fixed connection end 321 is connected with the bottom of another adjacent door body, and the bottom of the door body may also be provided with a cavity that can accommodate the fixed connection end 321 and the sliding connection end 322.

It should be noted that, the above-mentioned example of the sliding connection end 322 being installed in the top cavity of a door body to realize hidden installation is not limited thereto, and the fixed connection end 321 may also be installed in the top cavity of a door body as required, so that both the sliding connection end 322 and the fixed connection end 321 may be installed in a hidden manner; alternatively, the fixed connection ends 321 are mounted only in a cavity in the top of a door body. In addition, the sliding connection end 322 can be installed only in the cavity at the bottom of one door body to realize hidden installation, or only the fixed connection end 321 is installed in the cavity at the bottom of one door body, or the sliding connection end 200 is installed in the cavity at the bottom of one door body at the same time, and the fixed connection end 321 is installed in the cavity at the bottom of another adjacent door body, so that the sliding connection end 322 and the fixed connection end 100 can be installed at the bottom of the door body in a hidden mode at the same time.

The transmission belt 150 is fixed to one end of the door body connecting plate 160, and the other end of the door body connecting plate 160 is fixedly connected to the second door body 200, in this embodiment, the other end of the door body connecting plate 160 is fixed to the rear end of the second door body 160; when the motor 400 rotates to drive the first door body 100 to move along the transverse direction, the sliding support piece 510 and the sliding support piece 520 are fixed on the ground, and the first belt wheel 130 and the second belt wheel 120 move along with the door body to drive the transmission belt 150 to move, so that the door body connecting plate 160 drives the second door body 200 to move transversely. In one implementation, one end of the belt 150 may be fixedly wound around the sliding support 510, and the other end may be fixedly wound around the sliding support 520.
