In one embodiment, the hook, spring, receiving slot and limiting structure are arranged in pairs.

Based on the above, the wearable device of the present invention provides a novel structure, so that the main body and the strap can be assembled and disassembled using two different directions and gestures, thereby preventing the main body and the strap from being separated when the user does not expect it.

FIG. 1A is an exploded schematic diagram of a wearable device according to an embodiment of the present invention, FIG. 1B is a schematic diagram of the main body of FIG. 1A after being assembled and separated from the strap, and FIG. 1C is a schematic diagram of the strap and the main body being assembled together.

Please refer to FIG. 1A, FIG. 1B and FIG. 1C simultaneously. The wearable device 1 of this embodiment includes a strap 2 and a main body 3. The strap 2 has a strap 21 and an assembly area 22, wherein the assembly area 22 is located in the middle of the strap 21, and a limiting structure 23 is provided in the assembly area 22. The main body 3 is suitable for being assembled in the assembly area 22 along a first direction D1 to be combined with the strap 21.

The main body 3 includes an upper cover 31 and a lower cover 32, a stopper 33, a hook 34 and a spring 35. The upper cover 31 is coupled to the lower cover 32 along the first direction D1. The stopper 33 is assembled to the lower cover 32 and is located in the space formed by the upper cover 31 and the lower cover 32, wherein the stopper 33 has a receiving groove 331.

FIG. 2A is an exploded schematic diagram of the limit seat 33 and the lower cover 32 from another perspective, and FIG. 2B is a cross-sectional schematic diagram of the limit seat 33 of FIG. 2A being assembled on the lower cover 32. Please refer to FIG. 2A and FIG. 2B simultaneously. Specifically, the lower cover 32 has a limit groove 321 and a convex rib 322, and the limit seat 33 has an opening 332 corresponding to the convex rib 322. When the limit seat 33 is assembled on the lower cover 32, the limit seat 33 is located in the limit groove 321, and the convex rib 322 is correspondingly embedded in the opening 332.

By the way, in the depth direction of the opening 332 (i.e., the first direction D1), the aperture of the opening 332 may have a first aperture diameter r1 and a second aperture diameter r2, wherein the second aperture diameter r2 is substantially the same as the diameter of the convex rib 322, so that the convex rib 322 can be correspondingly embedded in the opening 332; in this way, the depth to which the convex rib 322 is embedded in the opening 332 can be limited by setting the first aperture diameter r1 smaller than the second aperture diameter r2.

When the upper cover 31 is assembled to the lower cover 32, the upper cover 31 simultaneously covers the limiting seat 33 to limit the limiting seat 33. It can be seen that through the arrangement of the upper cover 31, the limiting groove 321, the rib 322 and the opening 332, the limiting seat 33 is fixed to the lower cover 32 and cannot move in any direction relative to the lower cover 32.

FIG3A is a schematic diagram of the spring 35 and the hook 34 of FIG1A installed on the limit seat 33, and FIG3B is a three-dimensional schematic diagram of the hook 34 of FIG1A. Please refer to FIG1A, FIG3A and FIG3B simultaneously. The hook 34 of this embodiment is generally S-shaped, and has a first portion 341, a second portion 342 and a third portion 343. The second portion 342 has two ends 3421 and 3422, and the first portion 341 and the third portion 343 are respectively vertically connected to the two ends 3421 and 3422 of the second portion 342, wherein the third portion 343 is hook-shaped.

The second portion 342 of the hook 34 is located in the receiving groove 331, and the third portion 343 is disposed through the receiving groove 331, so that the hook 34 can be hooked with the limiting structure 23 to allow the main body 3 to be assembled to the strap 2. The upper cover 31 is covered with the limiting seat 33, so that the hook 34 is restricted to move relative to the receiving groove 331 in the receiving groove 331 along a second direction D2 perpendicular to the first direction D1.

As described above, the spring 35 is disposed in the receiving groove 331 , wherein a first end 351 of the spring 35 abuts against a groove wall 331 a of the receiving groove 331 , and a second end of the spring 35 abuts against the hook 34 .

Specifically, the spring 35 abuts against the first portion 341, wherein the first portion 341 further has a protruding column 341a, and the protruding direction of the protruding column 341a is opposite to the protruding direction of the hook of the third portion 343, and the second end 352 of the spring 35 is correspondingly sleeved on the protruding column 341a.

FIG4 is a schematic diagram of the position-limiting structure 23 in FIG1A. Referring to FIG1A and FIG4, the position-limiting structure 23 has a stopper 231 and a guide sidewall 232. The stopper 231 extends along the second direction D2, and the guide sidewall 232 extends along the first direction D1. The stopper 231 has a guide slope 2311 for guiding the hook 34 to move during the assembly of the main body 3 to the strap 2.

The guide side wall 232 has a first surface 2321 and a second surface 2322 extending along a third direction D3, wherein the first surface 2321 is an inclined surface, but not limited thereto, and the first surface 2321 may also be a curved surface.

5A to 5C are schematic diagrams showing the process of assembling the main body 3 to the strap 2. FIG.

As shown in FIG. 5A and FIG. 5B , the main body 3 is moved close to the strap member 2 along the first direction D1 to be assembled on the strap member 2, and the third portion 343 of the hook 34 first contacts the guiding slope 2311 of the stopper 231, and as the contact between the third portion 343 of the hook 34 and the guiding slope 2311 gradually deepens, the hook 34 and the guiding slope 2311 interfere with each other so that the hook 34 moves in the second direction D2. Specifically, the protrusion 341a of the first portion 341 of the hook 34 moves toward the groove wall 331a of the accommodating groove 331, and the hook 34 compresses the spring 35 while moving so that the spring 35 stores elastic restoring force.

As shown in FIG. 5B and FIG. 5C , as the hook 34 is inserted into the stopper 231 of the limiting structure 23 , when the guiding inclined surface 2311 and the third portion 343 no longer interfere with each other, the spring 35 releases its elastic restoring force to push the hook 34 back to its original position, so that the hook 34 and the stopper 231 are engaged together.

Please refer to FIG. 4 and FIG. 5C . Incidentally, the position limiting structure 23 of this embodiment has a bottom surface 233 , wherein when the hook 34 is hooked on the position limiting structure 23 , the third portion 343 may not contact the bottom surface 233 .

As can be seen from the above, the wearable device 1 of this embodiment can be assembled together through simple assembly actions.

Fig. 6A to Fig. 6C are schematic diagrams of the process of disassembling the main body 3 from the strap 2. Fig. 7A to Fig. 7C are schematic diagrams of the process of disassembling the main body 3 from the strap 2 from top view, wherein the upper cover 31 is omitted. Fig. 8A to Fig. 8C are schematic diagrams of the process of disassembling the main body 3 from the strap 2 from bottom view, showing the relative relationship between the hook 34 and the guide side wall 232.

6A, 7A and 8A, when the hook 34 is coupled to the stopper 231, the first portion 341 of the hook 34 is pressed against the other groove wall 331b of the receiving groove 331 by the spring 35. At this time, the third portion 343 of the hook 34 contacts a part of the first surface 2321 of the guide side wall 232.

As shown in FIG. 6B , FIG. 7B and FIG. 8B , the main body 3 is rotated relative to the assembly area 22, and the hook 34 is guided by the first surface 2321 to move toward the groove wall 331a against which the first end 351 of the spring 35 abuts. Incidentally, the angle of rotation of the main body 3 relative to the assembly area 22 is determined by the movement stroke of the main body 3 relative to the first surface 2321. In this embodiment, the angle of rotation of the main body 3 relative to the assembly area 22 is between 0 degrees and 15 degrees. In addition, although the first surface 2321 of this embodiment is described as an inclined surface, it is not limited thereto, and the first surface 2321 can also be a curved surface.

Then, as shown in FIG. 6C , FIG. 7C and FIG. 8C , as the hook 34 leaves the first surface 2321 and contacts the second surface 2322 , the hook 34 no longer interferes with the stopper 231 , and thus the hook 34 and the stopper 231 are released from being engaged with each other.

At this time, the main body 3 can be disassembled from the assembly area 22 in the opposite direction of the first direction D1.

At the same time, since the hook 34 no longer interferes with the limiting structure 23, the compressed spring 35 releases its elastic restoring force to return the hook 34 to its original position (the first portion 341 of the hook 34 abuts against the other groove wall 331b of the accommodating groove 331).

Please continue to refer to Figures 4, 6B and 6C. In this embodiment, in order to allow the user to more conveniently disassemble the main body 3 from the assembly area 22, the bottom surface 233 has a third surface 2331 and a fourth surface 2332 extending in the third direction D3, wherein the third surface 2331 is connected to the first surface 2321, and the fourth surface 2332 extends from the third surface 2331 in the opposite direction of the first direction D1, and the fourth surface 2332 is connected to the second surface 2322.

When the main body 3 rotates relative to the assembly area 22 and the hook 34 moves from the first surface 2321 to the second surface 2322 and releases the engagement with the stopping portion 231, the third portion 343 of the hook 34 contacts the fourth surface 2332 and is guided (lifted) by the fourth surface 2332, so that the hook 34 moves in the opposite direction of the first direction D1.

Although for the sake of convenience, the above partial figures only show one set of the hook 34, the spring 35, the receiving groove 331 and the limiting structure 23 and the related description is made according to the relative position relationship in the figure, the reader should be able to see from Figure 1A, Figures 5A to 5C, Figures 6A to 6C, Figures 7A to 7C and Figures 8A to 8C that the hook 34, the spring 35, the receiving groove 331 and the limiting structure 23 are arranged in pairs.

In summary, the wearable device of the present invention provides a novel structure, wherein the structural improvements of the hook and the limit structure enable the main body and the strap to be easily combined by simply pressing down the main body when assembling. In addition, when the main body is to be removed from the strap, the interference between the hook and the limit structure can be eliminated by rotating the main body from the strap. As can be seen from the above, assembly and disassembly can be achieved by using different directions and simple gestures.

In addition, since the assembly and disassembly of the main body and the strap are not straight up and down, it is possible to avoid the main body and the strap being separated when the user does not expect it.
