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.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application claims the benefit of U.S. Provisional Patent Application Ser. No. 63/665,006, filed on Jun. 27, 2024, the disclosure of which is incorporated by reference herein in its entirety. SUMMARY 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. In implementations, an electronic device is disclosed that includes an outer enclosure having a mechanical frame and one or more housing panels. The electronic device also includes a display that is attached to the outer enclosure. The outer enclosure and the display, when attached, define an internal cavity. The electronic device further includes a battery disposed within the internal cavity. The electronic device also includes a battery chassis on which the battery is attached. The battery chassis includes a plurality of shear stops that mechanically interlock with the mechanical frame. The plurality of shear stops are configured to constrain a movement of the battery chassis in at least two dimensions.

DETAILED DESCRIPTION Overview Portable electronic devices, including smartphones and laptops, have experienced consistently high consumer demand for the past decade. Billions of units of smartphones are manufactured and sold in a single year alone. The conveniences and services these portable electronic devices offer are now almost considered necessities in modern life. For example, navigation applications, telecommunication systems, and transactional services once were considered luxuries in the late 20th century but are now indispensable in the 21st century. To promote portable electronic devices' integration into the everyday lives of users, manufacturers design these devices to withstand environmental stresses, including ingress contaminants, external mechanical forces, and software-based attacks. Further to this end, manufacturers continue to pursue sleeker, more-aesthetic designs that also support increased battery capacities, minimized manufacturing costs, and improved repairability. Device designs that achieve reduced material usage and lower manufacturing time that also allow for increased battery capacity and simplified repairability save manufacturers and consumers large sums of capital and elevate user experience. For example, most smartphone designs include a rechargeable battery that is adhered to a structural component of the device, such as a frame or a housing panel. Thus, when a user seeks to replace a rechargeable battery and/or access an altogether separate internal electronic component (e.g., for repair, for replacement) that is physically inaccessible without first removing the rechargeable battery, the user may need to sever an adhesion between the rechargeable battery and the structural component. Aside from such a task being challenging and time consu
