Abstract: This document describes systems and techniques directed at a battery chassis for electronic devices. In aspects, a battery is attached to a battery chassis that mechanically interlocks with a mechanical frame of an electronic device. The battery chassis includes a plurality of shear stops that constrain a motion of the battery chassis and battery subassembly in at least two dimensions. The battery chassis and battery subassembly can be removed from the electronic device without severing an adhesive, facilitating device repair.

Abstract: This document describes systems and techniques directed at internal hardware configurations for foldable devices. In aspects, a foldable electronic device includes a housing, defining an internal cavity within which a battery is disposed, and one or more displays that are fixed to the housing, forming at least one internal cavity. The foldable electronic device further includes one or more battery cell tabs that are arranged in an unfolded configuration and extend from the battery to a power control module positioned underneath a display control module that is mounted to the display. Through such a configuration, an internal volume within the internal cavity can be more-efficiently occupied by increasing a battery capacity or reducing a dimensional profile of the foldable electronic device.

Abstract: This document describes systems and techniques directed at grounding of a removable battery subassembly of an electronic device. In aspects, a battery is attached to a battery chassis, forming a battery subassembly. The battery chassis mechanically and removably interlocks with a mechanical frame of an electronic device. The mechanical frame includes one or more ground contacts, each disposed proximate to an antenna integrated with the mechanical frame. The ground contacts provide grounding paths for the antennas to the battery chassis, which acts as a system ground. One or more additional ground contacts are disposed between the mechanical frame and a display of the electronic device. A combination of the ground contacts and the additional ground contacts provide another grounding path for the display to the battery chassis via the mechanical frame. These grounding techniques effectively mitigate the impact of lossy resonance on antenna performance.

Abstract: This document describes systems and techniques for narrow display borders using a display-to-frame interposer (“interposer”). In aspects, the interposer is bonded, on a first side, to a mechanical frame. On a second side, the interposer is bonded to a backside of a display panel module, including a folded portion, and supports a cover layer through the display panel module. In such a configuration, a display border, which extends from an edge of the cover layer to an active area of the display panel module and resides above the folded portion, can be reduced.

Abstract: This document describes an electronic device with a chassis and a vapor chamber positioned within the chassis. The vapor chamber includes a base plate and a cap portion attached to the base plate to form a sealed chamber. The base plate extends outward beyond the sealed chamber to form an extended portion with a first edge attached to a sidewall of the chassis and a second edge, in the form of a mechanical flange, connected to the chassis. The base plate with the extended portion forms the floor of a battery compartment within the chassis and provides a thermal path between the vapor chamber and the chassis. By integrating the vapor chamber into the structural components, the need for a separate mid-plate is eliminated, allowing for a thinner device that efficiently dissipates heat while maintaining structural rigidity.
