Description

A reversible connector for wearable device and wearable device thereof Technical Field

[0001] The present invention relates to the technical field of wearable device connectors, and in particular to a reversible connector for a wearable device and the wearable device thereof. Background Art

[0002] A double-sided watchband is a product that can be worn on both sides, usually with different patterns on each side, which is highly aesthetic. The reversible connector is used to turn the watchband over without removing it. Technical issues

[0003] The prior art also discloses watch straps that can be worn on both sides, such as Application No. 201920911254.7, which discloses a watch strap that can be worn on both sides, and Application No. 202122884725.X, which discloses a rotatable watch strap connection structure. The above patents are inseparable from elastic parts to achieve the flipping of watch straps. This is because the two components that are flipped relative to each other need to be limited by concave and convex structures, such as bosses and grooves, after the flip is achieved. Therefore, when flipping, it is necessary to use the elastic part to stretch, flip, and finally shrink and reset to achieve the limit. This structure is relatively complex and has high requirements for precision. Moreover, the elastic part is prone to failure after repeated use, which affects the user experience. In addition, some of the flipping structures in the prior art will also destroy the appearance of the watch particles, affecting the user experience. Technical Solutions

[0025] Furthermore, the first spring ear and / or the second spring ear are common spring ears, single-support switch spring ears or double-support switch spring ears.

[0026] For watches, the watch band is the small connecting module on the watch strap. When it is not necessary to cut lugs on the watch band to achieve connection, external connectors can be used to connect the watch bands, which can reduce the difficulty of cutting the watch bands. This is an I-shaped watch band in the prior art. This technology is not necessarily applicable to I-shaped watch bands, but can also be applied to other types of watch bands.

[0027] The present invention preferably uses a single-support switch spring tab to achieve a rotational connection between the meter pieces. Of course, other types of spring tabs, such as conventional spring tabs or dual-support switch spring tabs, can also be used in conjunction with a spring tab through-hole designed in the first connecting block. For the connector of the present invention, because the internal shaft needs to be installed and space is limited, a single-support switch spring tab is preferably used in conjunction with a spring tab blind hole designed in the first and second connecting blocks to effectively utilize space. For meter piece connections in other locations, a spring tab through-hole can be used. All of these are within the scope of protection of the present invention.

[0030] The present invention also provides a watch strap comprising the above-mentioned connector. Watch straps made using the watch strap flip structure of the present invention and variations of equivalent structures are within the scope of protection of the present invention.

[0031] Some embodiments of the present invention provide a double-sided wearable watchband flip structure, comprising a first connecting block, a second connecting block, a connecting column assembly, a spring ear and a positioning bead; the connecting column assembly comprises a rotating shaft and a rotating shaft fixing assembly; the spring ear is arranged through the first connecting block; the two ends of the spring ear are used to connect the watchband; one end of the positioning bead is fixed to the connecting end of the second connecting block; the connecting end of the first connecting block is provided with a positioning hole matching the positioning bead; one end of the rotating shaft is fixed to the connecting surface of the first connecting block; the middle part of the second connecting block is provided with a connecting hole that is plugged into the other end of the rotating shaft; the first connecting block and the second connecting block are relatively rotatably connected with the rotating shaft as the central axis; the second connecting block is also provided with an L-shaped through hole for installing the connecting column assembly, and the L-shaped through hole connects at least one outer surface of the second connecting block and the outer side surface of the second connecting block close to the first connecting block.

The connecting assembly mainly serves to connect the first connecting block and the second connecting block, and at the same time serves as a central axis to play a core positioning role during the rotation process; the spring ears are mainly used to connect the entire watch strap flip structure with the watch strap. The two ends of the spring ears can be connected to the watch strap or the watch head, both of which are within the scope of protection of the present invention. The design of the positioning beads and positioning holes is used to quickly connect and fix the first connecting block and the second connecting block after flipping to avoid relative position displacement.

[0033] There are two ways to implement the connecting column assembly of some embodiments of the present invention. In one embodiment, the rotating shaft fixing assembly includes a first shaft cover and a second shaft cover; one end of the rotating shaft is fixed in the middle of the first connecting block, and the other end is inserted into the connecting hole; the first shaft cover and the second shaft cover are interlocked to fix the upper and lower sides of the rotating shaft.

[0034] Since the rotating shaft has a certain length, there will be a movable area in the middle after it is connected to the first connecting block and the second connecting block, which may cause a gap between the first connecting block and the second connecting block; therefore, the present invention is designed to fix the rotating shaft with a first shaft cover and a second shaft cover, and the first shaft cover and the second shaft cover clamp the middle part of the rotating shaft to prevent the rotating shaft from loosening.

[0035] Furthermore, the first shaft cover is provided with a through hole, and the second shaft cover is provided with a clamping post, which passes through the through hole to secure the first shaft cover to the second shaft cover.

In this embodiment, the shaft is cylindrical, not bulging at either end. An L-shaped through-hole is provided at the upper end of the second connecting block to facilitate sequential insertion of the latch into the second and first fixing holes.

[0042] Preferably, the present invention further comprises decorative sheets attached to the upper and lower surfaces of the second connecting block. The decorative sheets not only serve to enhance the appearance, but also seal the L-shaped through-hole on the second connecting block to form a sealed structure and protect the internal components.

[0043] Furthermore, a spring ear through hole is provided inside the second connecting block, which can be used to pass a spring ear through the hole and then connect the watch strap or the watch head.

[0044] The present invention further provides a watch strap comprising the above-mentioned watch strap flip structure. Watch straps made using the watch strap flip structure of the present invention and variations of equivalent structures are within the scope of protection of the present invention.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] The connecting piece of the present invention adopts the connecting piece of the wearable device of this technology. It does not need to use elastic parts to achieve stretching and rebound, nor does it need to make high-precision concave and convex structures to achieve flip limiting. It has a long service life and is less difficult to make. Therefore, it is not only suitable for ordinary stainless steel products, but also suitable for products such as artificial fibers and natural fibers that are difficult to cut. The connection between the two connecting blocks can be made very tight, less dusty, and easy to clean.

[0047] The wearable device connector of the present invention has a simple overall structure and low cost. The entire watchband flips around a central axis, and positioning beads ensure post-flip positioning, making operation simple.

[0081] As shown in FIG6 and FIG8 , a set of spring ears is extended from both sides of the first connecting block 1 and the second connecting block 2 for detachably connecting the dial or the watch grain.

[0082] As shown in Figures 6 and 8, the ear group includes a first ear 101 embedded in the first connecting block 1, and a second ear 102 embedded in the second connecting block 2; the first connecting block 1 is connected to the second connecting block 2 via the first ear 101; the second connecting block 2 is externally connected to the dial via the second ear 102. In this case, the first connecting block 1 is a watch particle, one end of which is connected to the second connecting block 2 via the first ear 101, and the other end can be connected to other watch particles via an external connector. For watches, watch particles are small modules that connect sections on the watch strap. When you do not want to cut lugs on the watch particles to achieve connection, as shown in Figure 9, you can use an external connector 200 to achieve connection between the watch particles; this can reduce the difficulty of cutting the watch particles. This is an I-shaped watch strap in the prior art. For this technology, it is not limited to being applied to I-shaped watch straps, and can be other types of watch straps.

[0083] In this embodiment, the first spring ears 101 and the second spring ears 102 are each provided with two sets of single-support switch spring ears or single-sided common spring ears, and the first connecting block 1 and the second connecting block 2 are provided with spring ear blind holes 90 for installing the single-support switch spring ears.

[0084] The present invention preferably uses single-bracket switch spring tabs to achieve a rotational connection between the meter chips. Because the connector of the present invention requires the internal installation of a rotating shaft 3, space is limited. Therefore, single-bracket switch spring tabs are preferred, along with blind spring tab holes 90 designed within the first and second connecting blocks 1 and 2, to effectively utilize space. For meter chip connections in other locations, spring tab through-holes 40 can be used.

[0085] Specifically, the method of using the present invention is to pinch one end of the second connecting block 2 or the first connecting block 1 with your hand, without stretching, and directly flip it over, so that the positioning bead 5 retracts from the positioning hole 6; then the first connecting block 1 rotates around the rotating shaft 3, and when it rotates 180°, the positioning bead 5 contacts the positioning hole 6 to achieve positioning, and the flipping is completed. Example

[0086] As shown in FIG. 10 , the difference between this embodiment and the third embodiment is that ordinary spring tabs are used in conjunction with spring tab through holes 40 designed in the first connecting block 1 and the second connecting block 2 . Example

[0087] As shown in Figure 11, the difference between this embodiment and Example 3 is that a first magnetic part 201 is embedded in the end where the first connecting block 1 is connected to the second connecting block 2, and a second magnetic part 202 is provided at the end where the second connecting block 2 is connected to the first connecting block 1 for fixing the first magnetic part 201.

[0088] The positioning beads 5 and the positioning holes 6 are replaced with the first magnetic member 201 and the second magnetic member 202. This method makes adjustment more flexible. Furthermore, there are two of each of the first magnetic member 201 and the second magnetic member 202. Example

[0089] The present invention also provides a watchband or watch comprising the connector of any one of Examples 1 to 5. The watchband of the present invention is suitable for use in electronic watches, mechanical watches, smart watches, and other fields. Watchbands made using the watchband flip structure of the present invention, as well as variations with equivalent structures, are within the scope of protection of the present invention.

Although the present invention has been described in detail with reference to the above preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent replacements of the technical solutions of the present invention may be made without departing from the spirit and scope of the technical solutions of the present invention. Those skilled in the art may also make other changes within the spirit of the present invention and apply them to the design of the present invention, as long as they do not deviate from the technical effects of the present invention. These changes made in accordance with the spirit of the present invention should all be included in the scope of protection claimed by the present invention.
