A toolless computing housing assembly includes an enclosure, front lid, and first side cover. The enclosure includes connected panels defining a front opening and internal volume, with front toolless coupling features along its front opening and side toolless coupling features along its panels. The front lid includes lid toolless coupling features that interact with the front toolless coupling features of the enclosure to facilitate the ready removal and reassembly of the front lid from and to the enclosure without the use of tools. The first side cover includes an outer face, inner face, and a first set of side cover toolless coupling features that interact with the side toolless coupling features of the enclosure to facilitate the ready removal and reassembly of the first side cover from and to the enclosure without the use of tools. The toolless computing housing assembly also includes a second side cover and mounting arrangement.

A modular electronic power converter is disclosed and includes a first housing, a second housing, and a coupling element. The coupling element is arranged between the housings and is connected to at least one of the housings via a detent connection.

A locking device includes a bracket and a support plate arranged opposite to each other, a side of the support plate facing away from the bracket being used for carrying a display unit. One of the bracket and the support plate includes a first pin, and the other one of the bracket and the support plate includes a first switch. When the first switch is in a locked state, the first pin is inserted into the first switch, and the first switch resists the first pin from being pulled out. One of the bracket and the support plate includes a second pin, and the other one of the bracket and the support plate includes a second switch. When the second switch is in the locked state, the second pin is inserted into the second switch, and the second switch resists further insertion of the second pin.

The present disclosure provides a sub-display panel assembly, including: a display substrate; a frame, including: a bottom plate having a support surface and a mounting surface arranged opposite to each other, where the support surface is configured to bear the display substrate; and a first circuit board on a side of the bottom plate away from of display substrate, including: a first circuit board body connected to the mounting surface of the bottom plate through an elastic component, where the elastic component is configured to support the first circuit board body and enable the first circuit board body to move relative to the bottom plate. An embodiment of the present disclosure further provides a tiled display apparatus.
