Abstract
Description
Technical Field
[0001] This utility model relates to the field of smartwatch technology, and in particular to a quick-release device for smart wearables. Background Technology
[0002] Smart watch bands are typically worn on the wrist or neck, and there are currently two methods available:
[0003] The first type involves creating two mounting holes at both ends of the smart bracelet's casing. The accessories include two spring bar connectors and a lanyard. The spring bar connectors are for wrist wear. To install them, first attach the long and short watch straps to the two spring bar connectors, then fasten the two spring bar connectors into the two mounting holes on the smart bracelet. The removal method is the reverse of the installation method. The lanyard is for neckwear wear. To install it, insert the lanyard into the mounting hole at either end of the smart bracelet's band. To remove it, forcefully push the lanyard buckle out of the mounting hole on the smart bracelet's band. By assembling and interchangeable accessories, both wrist and neckwear wearing methods are achieved.
[0004] The second type uses the shape of a smart bracelet as a clasp (symmetrical or with a groove in the middle), paired with an integrated TPU soft rubber injection-molded hard rubber strap and a hard rubber lanyard loop. The TPU soft rubber injection-molded hard rubber integrated strap is for wrist wear; its installation method is to squeeze the smart bracelet into the TPU soft rubber integrated strap; its removal method is to use brute force to deform the TPU integrated strap and then remove the smart bracelet. The lanyard loop is for necklace wear; its installation method is to forcefully insert the smart bracelet into the lanyard loop; its removal method is the reverse of the installation method, forcefully pushing the smart bracelet out from the other side.
[0005] However, the first method involves openings at both ends of the smart watch band, affecting the overall appearance. Furthermore, the fastening force is generated through the plastic deformation of hard plastic, resulting in inconsistent strength, primarily affecting installation and disassembly: too tight and installation and disassembly become difficult; too loose and it easily falls off. The two spring bar accessories and the lanyard accessory are small, posing a risk of loss.
[0006] The second method uses the shape of a smart bracelet as the fastening point, but the slotting affects the overall appearance of the device; at the same time, it is difficult for users to identify the installation direction of the device during installation; the installation and removal are done by pulling and tugging with brute force, which is not a good user experience; and the processing cost of the TPU soft rubber injection molded hard rubber one-piece watch strap is high.
[0007] In summary, the above two methods have the following disadvantages: 1. The fastening method directly affects the appearance of the smart bracelet; 2. The user experience of installation and disassembly is not good; 3. There are many parts or the processing cost is high. Utility Model Content

The first locking block 021 is detachably connected to a second locking groove 018, which is located on the inner wall of the other side of the buckle hole 019.
[0046] When the first locking block 021 extends into the locking hole 019 and is in the second locking groove 018, the installation operation of the bottom shell 001 and the outer shell can be carried out.
[0047] When the first card block 021 separates from the second card slot 018, the bottom shell 001 and the outer shell can be disassembled.
[0048] The outer casing includes a strap loop 004 and a lanyard loop 007. The inner diameter of both the strap loop 004 and the lanyard loop 007 is 0.4 mm larger than the outer diameter of the bottom case 001.
[0049] The design is further optimized by providing a first clearance 006 on the watch band 004 between the two spring bars on one side of the watch band 004, and a fourth clearance 011 on the watch band 004 between the two spring bars on the other side of the watch band 004. The fourth clearance 011 is detachably connected to the button buckle 003.
[0050] The watch strap spring bars are all provided with mounting holes 005 for attaching the watch strap.
[0051] The design is further optimized by providing a second clearance position 009 at the hanging ring of the rope loop 007, and a third clearance position 010 on the side of the rope loop 007 opposite to the hanging ring of the rope loop 007. The third clearance position 010 is detachably connected to the button buckle 003.
[0052] The hanging ring 007 has a rope threading hole 008 on its eye for installing the hanging rope.
