Description

Wearable devices

This invention relates to a device, and more particularly to a wearable device.

With the development of wearable devices, watch-shaped wearable devices can be worn by users for extended periods to monitor heart rate, user exercise patterns, etc., and thus can be used to record and provide useful health information.

Currently, in common wearable devices, the main body is often too easily detached from the watch band; this causes inconvenience to users because the main body may separate from the watch band unexpectedly.

This invention provides a wearable device that prevents the main body from separating from the watch strap when the user does not expect it.

A wearable device according to the present invention includes a watchband and a main body. The watchband has a watchband and an assembly area, wherein the assembly area is located in the middle of the watchband and is provided with a limiting structure. The main body is assembled in the assembly area along a first direction and includes an upper cover and a lower cover, a limiting seat, a hook and a spring. The upper cover is joined to the lower cover along a first direction; the limiting seat is assembled on the lower cover and located in the space formed by the upper and lower covers, wherein the limiting seat has a receiving groove; the hook passes through the receiving groove and engages with the limiting structure, wherein the upper cover covers the limiting seat to restrict the hook to move only relative to the receiving groove along a second direction perpendicular to the first direction; a spring is correspondingly disposed in the receiving groove, a first end of the spring abuts against a groove wall of the receiving groove, and a second end of the spring abuts against the hook.

In one embodiment, the aforementioned limiting structure has a stop portion and a guide sidewall, the stop portion extending along a second direction and the guide sidewall extending along a first direction; when the main body rotates relative to the assembly area, the latch is guided by the guide sidewall to disengage from the stop portion.

In one embodiment, the aforementioned stop has a guide ramp, and when the latch moves along the first direction to engage with the limiting structure, the latch is guided by the guide ramp to move toward the groove wall of the receiving groove in the second direction and compress the spring.

In one embodiment, the guide sidewall has a first surface and a second surface extending along a third direction, the first surface being an inclined surface; when the main body rotates relative to the assembly area, the latch is guided by the first surface to disengage from the stop.

In one embodiment, the hook has a first part, a second part and a third part, the second part has two ends, and the first part and the third part are respectively perpendicularly connected to the two ends of the second part, a spring abuts against the first part, and the third part is hook-shaped.

In one embodiment, the first part described above further has a protrusion, and the second end of the spring is correspondingly fitted with the protrusion.

In one embodiment, the aforementioned limiting structure has a bottom surface, and when the hook is engaged with the limiting structure, the third part does not contact the bottom surface.

In one embodiment, the bottom surface has a third surface and a fourth surface, the fourth surface extending in the opposite direction from the third surface toward the first direction; when the main body rotates relative to the assembly area and the latch disengages from the stop, the latch is guided by the fourth surface to move in the opposite direction toward the first direction.

In one embodiment, the aforementioned main component rotates at an angle between 0 and 15 degrees relative to the assembly area.

In one embodiment, the hook, spring, receiving groove and limiting structure described above are provided in pairs.

Based on the above, the wearable device of the present invention provides a novel structure that allows the main body and the watchband to be assembled and disassembled using two different directions and gestures, thus avoiding the separation of the main body and the watchband from the user's unexpected situation.

Figure 1A is an exploded view of a wearable device according to an embodiment of the present invention; Figure 1B is a schematic diagram of the main body of Figure 1A after assembly and separation from the watch strap; and Figure 1C is a schematic diagram of the watch strap and the main body assembled together.

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

The main body 3 includes an upper cover 31 and a lower cover 32, a limiting seat 33, a latch 34, and a spring 35. The upper cover 31 is joined to the lower cover 32 along a first direction D1. The limiting seat 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 limiting seat 33 has a receiving groove 331.

Figure 2A is an exploded view of the limiting seat 33 and the lower cover 32 from another perspective, while Figure 2B is a cross-sectional view of the limiting seat 33 assembled with the lower cover 32. Referring to both Figures 2A and 2B, specifically, the lower cover 32 has a limiting groove 321 and a protruding rib 322, while the limiting seat 33 has an opening 332 corresponding to the protruding rib 322. When the limiting seat 33 is assembled with the lower cover 32, the limiting seat 33 is located in the limiting groove 321, and the protruding rib 322 is correspondingly embedded in the opening 332.

Incidentally, in the depth direction (i.e., the first direction D1) of the opening 332, the aperture of the opening 332 may have a first aperture r1 and a second aperture r2, wherein the second aperture r2 is approximately the same as the diameter of the protruding rib 322, so that the protruding rib 322 can be correspondingly embedded in the opening 332; thus, the depth of the protruding rib 322 embedded in the opening 332 can be limited by the setting that the first aperture r1 is smaller than the second aperture r2.

When the upper cover 31 is assembled onto the lower cover 32, the upper cover 31 simultaneously closes onto the limiting seat 33 to limit the limiting seat 33. Thus, through the arrangement of the upper cover 31, the limiting groove 321, the protruding rib 322, and the opening 332, the limiting seat 33 is fixed to the lower cover 32 and cannot move relative to the lower cover 32 in any direction.

Figure 3A is a schematic diagram of the spring 35 and the hook 34 of Figure 1A installed on the limiting seat 33, and Figure 3B is a three-dimensional schematic diagram of the hook 34 of Figure 1A. Referring to Figures 1A, 3A and 3B at the same time, the hook 34 of this embodiment is generally S-shaped, having a first part 341, a second part 342 and a third part 343. The second part 342 has two ends 3421 and 3422, and the first part 341 and the third part 343 are respectively vertically connected to the two ends 3421 and 3422 of the second part 342, wherein the third part 343 is hook-shaped.

The second part 342 of the latch 34 is located in the receiving groove 331, while the third part 343 is disposed through the receiving groove 331, so that the latch 34 can engage with the limiting structure 23 to allow the main body 3 to be assembled onto the watch strap 2. Wherein, by the upper cover 31 covering the limiting seat 33, the latch 34 is restricted to moving only relative to the receiving groove 331 in 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 331a 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 part 341, wherein the first part 341 also has a protrusion 341a, and the protrusion direction of the protrusion 341a is opposite to the protrusion direction of the hook of the third part 343, and the second end 352 of the spring 35 is correspondingly fitted with the protrusion 341a.

Figure 4 is a schematic diagram of the limiting structure 23 in Figure 1A. Referring to both Figure 1A and Figure 4, the limiting structure 23 has a stop portion 231 and a guide sidewall 232. The stop portion 231 extends along the second direction D2, while the guide sidewall 232 extends along the first direction D1. The stop portion 231 has a guide ramp 2311 to guide the hook 34 to actuate during the assembly of the main body 3 onto the watch strap 2.

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

Figures 5A to 5C are schematic diagrams of the assembly of the main component 3 onto the watch strap component 2.

As shown in Figures 5A and 5B, the main body 3 is assembled onto the watch strap 2 along the first direction D1. The third part 343 of the hook 34 first contacts the guide slope 2311 of the stop part 231. As the contact between the third part 343 of the hook 34 and the guide slope 2311 deepens, the mutual interference between the hook 34 and the guide slope 2311 causes the hook 34 to move in the second direction D2. Specifically, the hook 34 moves towards the groove wall 331a of the receiving groove 331 with the protrusion 341a of its first part 341. At the same time as the hook 34 moves, the spring 35 is compressed, causing the spring 35 to store elastic restoring force.

As shown in Figures 5B and 5C, as the hook 34 engages with the stop portion 231 of the limiting structure 23, when the guide ramp 2311 and the third part 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 stop portion 231 engage together.

Please refer to Figures 4 and 5C simultaneously. Incidentally, the limiting structure 23 of this embodiment has a bottom surface 233, wherein when the hook 34 is engaged with the limiting structure 23, the third part 343 and the bottom surface 233 may not be in contact.

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

Figures 6A to 6C are schematic diagrams illustrating the assembly and disassembly of the main body component 3 and the watch strap component 2. Figures 7A to 7C are top-view schematic diagrams illustrating the assembly and disassembly of the main body component 3 and the watch strap component 2, omitting the top cover 31. Figures 8A to 8C are bottom-view schematic diagrams illustrating the relative relationship between the latch 34 and the guide side wall 232 during the assembly and disassembly of the main body component 3 and the watch strap component 2.

Referring simultaneously to Figures 6A, 7A, and 8A, when the hook 34 is engaged with the stop portion 231, the first part 341 of the hook 34 is pushed against the other groove wall 331b of the receiving groove 331 by the spring 35. At the same time, the third part 343 of the hook 34 simultaneously contacts a portion of the first surface 2321 of the guide side wall 232.

As shown in Figures 6B, 7B, and 8B, when the main body 3 is rotated relative to the assembly area 22, the latch 34 is guided by the first surface 2321 and moves 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 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. Furthermore, although the first surface 2321 in this embodiment is illustrated as an inclined surface, it is not limited thereto; the first surface 2321 can also be a curved surface.

Then, as shown in Figures 6C, 7C and 8C, as the hook 34 leaves the first surface 2321 and comes into contact with the second surface 2322, the hook 34 no longer interferes with the stop part 231, thus releasing the hook 34 from the stop part 231.

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

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

Please continue to refer to Figures 4, 6B and 6C. In this embodiment, in order to make it easier for users to 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. 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 to 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 is released from the engagement with the stop part 231, the third part 343 of the hook 34 contacts the fourth surface 2332 and is guided (lifted) by the fourth surface 2332, so the hook 34 moves in the opposite direction of the first direction D1.

For ease of explanation, the above figures only depict one set of hooks 34, springs 35, receiving slots 331, and limiting structures 23, and the explanations are based on their relative positions in the figures. However, the reader should be able to see from Figures 1A, 5A to 5C, 6A to 6C, 7A to 7C, and 8A to 8C that hooks 34, springs 35, receiving slots 331, and limiting structures 23 are arranged in pairs.

In summary, the wearable device of this invention provides a novel structure. Through structural improvements using hooks and limiting mechanisms, the main body and strap can be easily joined by simply pressing down on the main body during assembly. Furthermore, when removing the main body from the strap, the interference between the hooks and limiting mechanisms can be released by rotating the device, allowing for easy detachment. As can be seen from the above, assembly and disassembly can be achieved using different directions and simple hand gestures.

Furthermore, since the assembly and disassembly of the main body and the watch strap are not done in a straight line, it can prevent the main body and the watch strap from separating unexpectedly.
