Description

Technical Field

[0001] This utility model relates to the field of watch case technology, specifically to a smart watch case sleeve with a snap-fit ​​structure. Background Technology

[0002] A smart watch case is a smart upgrade accessory that adapts to traditional mechanical or quartz watches. It consists of a lightweight case frame (fitted to the watch size, 3-5mm thick) made of materials such as aluminum alloy, titanium alloy, or ceramic, built-in micro sensors (accelerometer, heart rate monitoring module), a low-power Bluetooth chip, and a rechargeable lithium battery (7-14 days of battery life). It is fixed to the outside of the watch via a clip or magnetic attachment, without altering the original watch structure. It can collect the wearer's activity data (steps, distance, calories), heart rate, and sleep status in real time. The data is synchronized to a mobile app via Bluetooth to generate a health report. Some models integrate an NFC module for quick payments. The case surface has a scratch-resistant coating (hardness ≥9H), and touch buttons or sensor areas are located on the side for operation. It serves the dual purpose of protecting the watch case from impacts and expanding smart functions. It is compatible with various watch diameters (38-46mm), meeting users' needs for a smart experience while retaining the traditional watch appearance.

[0003] To address this, China Patent Network published an Apple Watch case with application number 202323606135.6. By using an aluminum alloy frame fitted over the outside of the case body, the overall hardness of the case is increased, thereby improving its impact resistance and preventing direct pressure on the phone inside the case during a collision. The aluminum alloy frame also enhances the aesthetics of the case, solving the problems of poor impact protection and poor aesthetics.

[0004] While the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: when using existing watches, their transparent screens are exposed to the outside world, which makes it easy for the transparent screens to collide with external objects, causing scratches or damage to the surface of the transparent screens, thus resulting in a waste of transparent screen resources. Based on this, this utility model designs a smart watch case with a buckle structure to solve the above problems. Utility Model Content
