Description

Technical Field

[0001] This utility model belongs to the field of smart wearable technology, and in particular relates to a rotating quick-release device for smart wearables. Background Technology

[0002] To meet users' needs for flexible switching between wearing on the wrist and on a neckband, existing technologies for smart wearable devices (such as smart bands and smartwatches) mainly employ two methods to achieve the detachment and interchangeability of wearing accessories:

[0003] The first method involves setting two mounting holes at both ends of the smart watch band's housing, along with two spring bar accessories (for wrist strap connection) and one lanyard accessory (for necklace wear). During installation, the long and short watch straps must first be clipped onto the spring bar accessories, and then the spring bar accessories are inserted into the mounting holes in the housing. To switch to necklace wear, the lanyard accessory is inserted into the mounting hole at either end of the housing; removal requires force to push the lanyard accessory out of the mounting hole. This method has the following drawbacks: the mounting holes at both ends of the housing detract from the overall appearance; the fastening force relies on the plastic deformation of the hard plastic, leading to difficulty in disassembly when installed too tightly and easy detachment when too loose, resulting in unstable fastening force; the spring bar accessories and lanyard accessory are small and easily lost.

[0004] The second method involves incorporating a clasp (such as a symmetrical structure or a central groove) into the smart bracelet's design, paired with a one-piece strap (wrist-worn) made of TPU soft rubber injection-molded hard rubber and a lanyard loop made of hard rubber (neckband-worn). Installation requires forcibly inserting the smart bracelet into the strap or lanyard loop, while removal necessitates brute force to deform the strap or push the bracelet out from the other side. The drawbacks of this method are: the grooved clasp on the casing affects the appearance; the symmetrical design makes it difficult for users to identify the orientation during installation; the reliance on brute force during installation and removal results in a poor user experience; and the processing cost of the TPU soft rubber injection-molded hard rubber one-piece strap is relatively high.

[0005] In summary, the existing technologies for assembling and disassembling accessories for smart wearable devices generally suffer from problems such as affecting appearance, poor user experience, easy loss of parts, or high processing costs. There is an urgent need for a quick-release structure that can balance appearance integrity, ease of operation, and cost advantages. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a rotating quick-release device for smart wearables.

[0007] To achieve the above objectives, this utility model provides a rotating quick-release device for smart wearables, comprising:

[0008] The bottom shell is fixed to the body of the smart wearable device. The side surface of the bottom shell is provided with a groove. An elastic arm extending along the edge of the bottom shell is provided in the groove. One end of the elastic arm is fixed to the inner wall of the groove, and the other end is suspended. A first protrusion is provided on the elastic arm.

[0009] The wearable connector is a ring-shaped structure adapted to the bottom shell, with a locking part on its inner side that engages with the first protrusion of the elastic arm, and an operating part on its side surface that corresponds to the elastic arm.

[0010] The bottom shell and the wearable connector are assembled by relative rotation: during the rotation, the engaging part squeezes the elastic arm to deform it. When the rotation reaches a preset angle, the elastic arm restores its deformation and engages with the engaging part through the first protrusion to form a lock.

[0011] The bottom shell and the wearable connector are disassembled in the following way: the elastic arm is deformed by the operating part to release the engagement between the first protrusion and the engaging part, and then separated after being rotated in the opposite direction to a preset angle.

[0012] Optionally, the side surface of the bottom shell is provided with an L-shaped groove, and the inner side of the wearable connector is provided with a second protrusion that matches the L-shaped groove. The second protrusion is embedded in the L-shaped groove to guide the relative rotation of the bottom shell and the wearable connector.

[0013] Optionally, the bottom shell is circular, and its side face has a raised step with a Type-C connector opening at a position different from that of the elastic arm.

[0014] Optionally, the first protrusion is sloped, and the engaging part of the wearable connector is a protrusion or buckle that matches the first protrusion.

[0015] Optionally, the inner diameter of the wearable connector is 0.4 mm larger than that of the bottom shell, and its inner side is provided with clearance positions that are adapted to the raised steps, as well as at least three silicone pad mounting positions.

[0016] Optionally, the back of the wearable connector is provided with identification characters to indicate the installation and removal direction.

[0017] Optionally, the wearable connector is a watch strap ring with mounting ears at both ends, and the mounting ears have watch strap spring bar mounting holes.

[0018] Optionally, the wearable connector is a lanyard loop with a hanging ring fixed to its side for connecting a lanyard.

[0019] Optionally, the preset angle is 20 degrees, and the elastic arm generates a snapping feedback sound when it recovers its deformation.

[0020] Compared with the prior art, the present invention has the following advantages and technical effects:

[0021] User experience optimization: The "rotation + snap-fit" structure enables quick assembly and disassembly. During installation, "one plug and one twist" is all it takes to get it in place, and during disassembly, "one press and one twist" is all it takes to separate it. The operation is convenient and the feedback is clear ("click" sound prompt), requiring no brute force.

[0022] Highly compatible accessories: The strap loop is compatible with universal watch straps, and the lanyard loop is compatible with universal lanyards, eliminating the need for custom-made accessories and reducing user costs.

[0023] Cost and appearance advantages: The elastic arm is designed using the toughness of plastic materials, reducing the number of parts and assembly steps; there are no additional openings or slots, maintaining the integrity of the equipment's appearance; and the production cost is low due to the use of ordinary injection molding processes.
