A fixing device includes a pedestal (10), provided with a first chute (11) extending along a first direction, a first limiting part being provided in the first chute (11); a bracket (20), detachably provided on the pedestal (10), wherein a slide block (21) is provided on the bracket (20), a limited part adapted to the first limiting part in shape is provided on the slide block (21), and the first limiting part and the limited part form a buckled structure so as to fix the bracket (20) on the pedestal (10) along a vertical direction; and a connecting arm (30), wherein a first end of the connecting arm (30) is provided on the bracket (20), and a mounting part (31) connected with a display screen is provided at a second end of the connecting arm (30). By the matching between the slide block (21) and the first chute (11), the first limiting part and the limited part form the buckled structure, so that the fixing device is reusable and convenient to assemble and disassemble.

A modular and reconfigurable stand is provided. The stand has legs that support bolt plates and the bolt plates are bolted to brace assemblies. The brace assemblies support shelves. The brace includes structurally identical cross damping support arms. The brace assembly also includes structurally identical first and second brace mounts. Each of the cross damping support arms is connected to each of the first and second brace mounts, and the brace mounts are connected to two legs. Double damper brace assemblies are also provided. In another embodiment a modular performance stand is provided having cross damping support arms that are connected to first and second modular shelf mounts having channels. The channels support four or more isolator elements. The modularity of the cross damping support arms and modular shelf mounts allows the width and depth of the modular performance stand to be varied to optimize performance.

A control method for smart furniture includes a furniture body, a movable part, and a concealing part, a cavity for receiving the movable part being disposed on the furniture body, the concealing part part's deployed position for concealing the cavity and retracted position for exposing the cavity being provided on the furniture body, a first drive device and a second drive device being provided in the furniture body, inside the furniture body being further provided a sensor, a controller, and a receiving box, the controller being connected to the sensor and the receiving box; the control method is to control movements of the movable part and the concealing part based on the control instruction. The control method may realize position shift between the concealing part and the movable part to satisfy user needs, without interference arising during the switching process.

A kit for aligning and fixing within a first tolerance range a support structure for a tiled display wall. The support structure comprises a plurality of channel profiles arranged vertically, and a plurality of frame assemblies configured to be arranged in a first row of frames. The kit further comprises a plurality of bottom supports to be aligned within a second tolerance range larger than the first tolerance range, and configured to be fixed to the channel profiles, a plurality of top supports configured to be fixed to the channel profiles, and supporting means comprising a plurality of spring loaded suspension blocks configured to be attached to the bottom supports, such that, when the frame assemblies are laid on the supporting means, the supporting means support the frame assemblies while aligning and fixing the frame assemblies, within the first tolerance range, to the top supports.
