Title:
CARBON FIBER WATCHCASE AND PREPARATION METHOD THEREFOR, AND SMART WATCH
Document Type and Number:
WIPO Patent Application WO/2023/231955
Kind Code:
A1
Abstract:
A carbon fiber watchcase (10), comprising a main body structure (1) and an electrically conductive structure (2), wherein the main body structure (1) has an inner surface (a1) and an outer surface (a2); and the electrically conductive structure (2) has a first contact located on the inner surface (a1), and a second contact located on the outer surface (a2), so as to connect the inner surface (a1) and the outer surface (a2) of the carbon fiber watchcase (10). The main body structure (1) comprises a braided body (11) and a polymer body (12), wherein the braided body (11) comprises carbon fibers, and the braided body (11) has a mesh structure; and the polymer body (12) at least fills gaps in the mesh structure of the braided body (11), such that the braided body (11) and the electrically conductive structure (2) form an integrated structure. By means of the electrically conductive structure (2), the inner surface (a1) and the outer surface (a2) of the main body structure (1) can realize an electrical conduction function, such that when the carbon fiber watchcase (10) is applied to an electronic device, the electromagnetic signal transmission of an electronic product is prevented from being affected by the electromagnetic shielding of the carbon fibers. Also provided are a preparation method for the carbon fiber watchcase (10), and a smart watch.
