[0041] The core of the present invention is to provide a detachable watchband that can be replaced, has a simple structure, is easy to replace, and has a highly reliable connection between the watchband and the watch face, making it less likely to fail or become detached. Another core of the present invention is to provide a wrist-worn device that includes the detachable watchband.
[0042] Please refer to Figure 1-Figure 7 .
[0043] This specific embodiment discloses a detachable watch strap, comprising: a watch strap body 1; a snap-fit portion, comprising a protrusion and a rotating shaft connected to the protrusion and driving the protrusion to rotate between a first position and a second position; the rotating shaft is arranged on the watch strap body, and the protrusion extends out of the watch strap body; when the rotating shaft rotates to the first position, the protrusion is engaged with the snap-fit portion of the dial, and when the rotating shaft rotates to the second position, the protrusion is released from the snap-fit portion of the dial.
[0044] It should be noted that in order to avoid affecting the comfort of wearing, the snap-on portion can be provided inside the strap body 1 .
[0045] During the use of the detachable watch strap provided in this specific embodiment, when the watch strap needs to be replaced, first, rotate the rotating shaft 32 and rotate the protrusion 31 to the second position, release the engagement between the engaging portion and the engaging slot portion of the dial, release the engaging connection between the watch strap body 1 and the dial, and remove the old watch strap; then prepare a new watch strap, and make the protrusion 31 on the new watch strap engage with the engaging slot portion of the dial, rotate the rotating shaft 32 and rotate the protrusion 31 to the first position, so that the protrusion 31 engages with the engaging slot portion, realizes the connection between the dial and the new watch strap, and completes the watch strap replacement process.
[0046] Compared with the prior art, the detachable watch strap provided in this specific embodiment has a simple structure, a small number of parts, a convenient replacement process, and is easy to operate, and can realize the replacement of watch straps of different materials and colors; and the watch strap body 1 and the dial are connected through the snap-fitting cooperation between the snap-fitting part and the snap-fitting part, which improves the connection reliability between the watch strap body 1 and the dial and is not easy to fail and disengage.
[0047] In a specific embodiment, the rotating shaft 32 is movably arranged along the axial direction relative to the strap body 1, and a spring 33 is provided on the outer periphery of the rotating shaft 32. One end of the spring 33 abuts against the strap body 1, and the other end abuts against the end of the rotating shaft 32, so that the protrusion 31 extending out of the strap body 1 has a tendency to move along the axial direction of the rotating shaft 32 toward the strap body 1.
[0048] like Figure 4 As shown, a cover plate 34 is provided at the end of the strap body 1, and the rotating shaft 32 is provided through the cover plate 34. A shaft sleeve is provided in the strap body 1, and the end of the rotating shaft 32 facing away from the protrusion 31 is provided in the shaft sleeve. One end of the spring 33 abuts against the cover plate 34, and the other end is connected or abutted with the end of the rotating shaft 32 facing away from the protrusion 31.
[0049] In order to facilitate the contact between the spring 33 and the rotating shaft 32 , a convex ring may be provided on the rotating shaft 32 along a direction perpendicular to the axial direction thereof.
[0050] In this specific embodiment, when the protrusion 31 is driven by the rotating shaft 32 to rotate to the first position and engages with the slot portion of the dial, since the protrusion 31 has a tendency to move along the axial direction of the rotating shaft 32 toward the strap body 1, the protrusion 31 will squeeze the slot portion toward the strap body 1, so that the strap and the dial are tightly connected, further improving the reliability of the connection between the strap and the dial.
[0051] In a specific embodiment, if Figure 4 As shown, the rotating shaft 32 is provided with a toggle member 321 for facilitating its rotation, and an opening slot 11 is provided on the inner side of the strap body 1 to expose the toggle member 321 .
[0052] The inner side of the strap body 1 mentioned in this specific embodiment refers to the surface of the strap body 1 that contacts the user, which prevents the toggle member 321 from being exposed to the outside and accidentally toggled; it also prevents impurities from entering the toggle member 321.
[0053] like Figure 4As shown, the watchband body 1 is provided with a limiting structure for limiting the rotation angle of the toggle member 321. Specifically, the toggle member 321 can be configured as a fan-shaped structure, and the limiting structure is a protrusion provided on the watchband body 1. When the fan-shaped structure rotates to one side and contacts the limiting structure, the protrusion 31 is in a first position. When the fan-shaped structure rotates to the other side and contacts the limiting structure, the protrusion 31 is in a second position. Of course, the toggle member 321 and the limiting structure can also have other structural forms that meet the requirements, which are determined according to actual conditions.
[0054] In this specific embodiment, the limiting structure is provided to control the rotation angle of the rotating shaft 32 and enable the protrusion 31 to rotate accurately to the first position and the second position.
[0055] In addition to the above-mentioned detachable watch strap, the present invention also provides a wrist-worn device, which includes: a watch strap body 1; a dial connector 2 for connecting to the watch dial; a snap-fitting portion, including a protrusion 31 and a rotating shaft 32 connected to the protrusion 31 and driving the protrusion 31 to rotate between a first position and a second position; one of the watch strap body 1 and the watch dial is provided with a snap-fitting portion; the protrusion 31 extends out of the watch strap body 1 or the watch dial; and the other of the watch strap body 1 and the watch dial is provided with a slot portion for engaging or releasing with the snap-fitting portion.
[0056] The wrist-worn device mentioned in this specific embodiment can be a smart watch, a smart bracelet, etc., or other devices that meet the requirements, which is determined according to actual conditions.
[0057] The dial connector 2 can be detachably connected to the dial by screws, or connected to the dial by other connection methods, or the dial connector 2 and the dial can be configured as an integrated structure, which is determined according to actual conditions.
[0058] During actual use, the dial connector 2 and the dial can be an integrated structure or fixedly connected. During the process of replacing the strap body 1, the dial connector 2 does not need to be replaced; the dial connector 2 can also be detachably set on the dial, and the dial connector 2 can be replaced when necessary.
[0059] The strap of the wrist-worn device in this specific embodiment can be replaced as needed, and the replacement process is convenient. After replacement, the connection between the strap body 1 and the dial connector 2 has high reliability and is not easy to loosen.
[0060] In a specific embodiment, the clamping portion is provided on the strap body 1; the clamping slot portion is provided on the dial connector 2; the clamping portion includes a protrusion 31 extending out of the strap body 1 and a rotating shaft 32 connected to the protrusion 31 and driving the protrusion 31 to rotate between a first position and a second position; the clamping slot portion includes a cavity structure 21 provided on the dial connector 2 and a through hole 22 passing through the wall of the cavity structure 21; when the protrusion 31 rotates to the second position, it can pass through the through hole 22 into the cavity structure 21 or escape from the cavity structure 21. When the protrusion 31 rotates to the first position in the cavity structure 21, the protrusion 31 is clamped in the cavity structure 21.
[0061] Of course, the snap-fitting portion may also be provided on the dial connector 2 and the snap-fitting portion may be provided on the strap body 1 . The specific method is determined according to the actual situation and will not be elaborated here.
[0062] like Figure 5 As shown, the through hole 22 can be a rectangular hole, and the protrusion 31 is a cuboid that fits in the rectangular hole. When the cuboid rotates to a first position within the cavity structure 21, the cuboid is locked in the cavity structure 21; when the cuboid rotates to a second position, it can be released through the through hole 22. The through hole 22 can also be an oblong hole, an arc hole, or other shapes, depending on the actual situation.
[0063] During specific use, when it is necessary to release the connection between the strap body 1 and the dial connector 2, it is necessary to control the rotating shaft 32 to drive the protrusion 31 to rotate to the second position so that the protrusion 31 can be disengaged from the through hole 22, and then replace the new strap, and control the rotating shaft 32 of the new strap to drive the protrusion 31 to rotate to the second position so that the protrusion 31 of the new strap passes through the through hole 22 into the cavity structure 21, and then control the rotating shaft 32 to drive the protrusion 31 to rotate to the first position in the cavity structure 21, so that the protrusion 31 is engaged in the cavity structure 21 to prevent the protrusion 31 from disengaging from the through hole 22.
[0064] Compared with the prior art, the cooperation between the snap-fitting portion and the slot portion in this specific embodiment has a simple structure and is easy to operate, and the protrusion 31 can penetrate deep into the cavity structure 21, which can effectively prevent external force from directly acting on the protrusion 31, further improving the connection reliability between the strap body 1 and the dial connector 2.
[0065] In a specific embodiment, a groove 23 is provided on the surface of the dial connector 2 facing the cavity structure 21 , and the protrusion 31 is provided with a positioning protrusion 311 that cooperates with the groove 23 , and when the protrusion 31 rotates to the first position, the positioning protrusion 311 is located in the groove 23 .
[0066] like Figure 6As shown, the groove 23 is arranged on the inner surface of the side wall where the dial connector 2 contacts the strap body 1. When the protrusion 31 is rotated to the first position, the positioning protrusion 311 is just located in the groove 23. Under the elastic force of the spring 33, the positioning protrusion 311 and the groove 23 are engaged and engaged, which can effectively improve the reliability of the strap body 1 and the dial connector 2.
[0067] Of course, the groove 23 can also be set on the surface of the dial connector 2 corresponding to the outer peripheral side wall of the protrusion 31. When the protrusion 31 is rotated to the first position, the positioning protrusion 311 is just located in the groove 23, so that the rotating shaft 32 is fixed in the axial position, which can effectively improve the reliability of the strap body 1 and the dial connector 2.
[0068] In this specific embodiment, when the protrusion 31 is rotated to the first position, the positioning protrusion 311 is located in the groove 23. If you want to release the connection between the strap body 1 and the dial connector 2, you need to release the cooperation between the groove 23 and the positioning protrusion 311, and rotate the protrusion 31 to the second position, which increases the difficulty of releasing the connection between the strap body 1 and the dial connector 2, and can effectively prevent the strap body 1 from detaching from the dial connector 2, further improving the reliability of the strap body 1 and the dial connector 2.
[0069] The groove 23 can be set as an arc groove. Specifically, the groove 23 can be a hemispherical groove 23 to avoid the blocking phenomenon between the positioning protrusion 311 and the groove 23, so that the cooperation between the groove 23 and the positioning protrusion 311 can be released smoothly.
[0070] In a specific embodiment, if Figure 5 、 6 As shown, a limiting protrusion 24 is provided on the surface of the dial connector 2 facing the cavity structure 21 , and the limiting protrusion 24 is used to limit the rotation angle of the protrusion 31 in the cavity structure 21 .
[0071] During specific use, after the protrusion 31 passes through the through hole 22 and enters the cavity structure 21, the setting of the limiting protrusion 24 can limit the rotation direction of the protrusion 31, so that the protrusion 31 can only rotate to the first position according to the preset rotation direction.
[0072] One of the strap body 1 and the dial connector 2 is provided with a guide post 35, and the other is provided with a guide groove that cooperates with the guide post 35, so as to guide and position the strap body 1 and the dial connector 2 during assembly. Figure 7 As shown, the guide column 35 is provided on the strap body 1 .
[0073] During actual use, the guide post 35 can be inserted into the guide groove to limit the relative movement direction of the strap body 1 relative to the dial connector 2 during assembly.
[0074] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
