Description

Technical Field

[0001] This utility model relates to the technical field of door panel accessories, and in particular to a load-bearing wheel set and door panel. Background Technology

[0002] Currently, most companies and organizations use electric sliding doors as their main entrances for employees and vehicles. For passageways with large spans, electric sliding doors typically require a structure with two or more door sections, where opening and closing are achieved through the mutual transmission of multiple door sections. In existing multi-stage transmission door structures, such as the one disclosed in patent application CN202323500085.3, the drive end of the sprocket driver is connected to one of the sprockets within the first lower crossbeam. A chain limiting plate is fixed to the chain within the first lower crossbeam and is also positioned on a lower pulley connecting assembly. The lower end of the vertical beam is connected to the lower pulley via the lower pulley connecting assembly; the upper end of the vertical beam is connected to the upper pulley via an upper pulley connecting assembly. Chain limiting seats are installed at the bottom of both the right door mounting bracket and the door mounting bracket. The chain limiting seat on the right door mounting bracket is fixed to the chain within the second lower crossbeam, and the chain limiting seat on the door mounting bracket drives the chain transmission within the second lower crossbeam of the next second door section. This application solves the problem that in existing multi-stage transmission gate structures, multiple sprocket drive mechanisms are required to achieve synchronous transmission of each gate, which not only increases the installation cost of the entire multi-stage transmission gate structure, but also makes the entire multi-stage transmission gate structure complex and cumbersome.

[0003] However, the above technical solutions still have room for improvement. For example, in passageways with large spans, vehicles often pass through frequently. After long-term use, the ground of the passageway will become uneven due to the pressure from vehicles. In this case, ordinary door panels cannot adapt to the ground, which may cause the door panel base to be suspended or squeezed during the movement of the door panel. This may cause the door panel to get stuck during the movement, or even damage the door panel and require repair. Utility Model Content
