With reference to FIG. 1, in some embodiments, a wristwatch (including a smart watch and a mechanical watch) is taken as an example to illustrate a wearable apparatus 10. The wearable apparatus 10 may include a dial 100 with a first watch strap 200 and a second watch strap 300. The first watch strap 200 may connect with a side of the dial 100, and the second watch strap 300 may connect with an opposite side of the dial 100. The first watch strap 200 and the second watch strap 300 may cooperate with each other to enable a user's wearing operation on the wearable apparatus 10 like a wristwatch. It should be appreciated that, in other embodiments, the wearable apparatus 10 may also be a smart bracelet or a smart armlet, which is not limited herein.

As shown in FIG. 2, the dial 100 may include a first side wall 110 and a second side wall 120 arranged opposite to each other. In some embodiments, the first side wall 110 may define a first mounting groove 111 and the second side wall 120 may define a second mounting groove. It should be noted that, the first side wall 110 and the second side wall 120 could be regarded as a part of the side peripheral face 100a of the dial 100. In other words, the dial 100 could define the first mounting groove 111 and the second mounting groove on its side peripheral face 100a.

The first watch strap 200 may be connected to the first side wall 110 of the dial 100. In some embodiments, referring to FIGS. 3 and 4, the first watch strap 200 may include a first strap body 210 and a first mounting portion 220 connected to one end of the first strap body 210. The first mounting portion 220 could be inserted in the first mounting groove 111, so as to realize a detachable connection between the first watch strap 200 and the dial 100. For example, the first mounting portion 220 may be inserted in the first mounting groove 111 and then could be locked in the mounting groove 111 through a fastener such as a spring bar. It should be appreciated that, in other embodiments, the first mounting portion 220 could be omitted. In these cases, the first strap body 210 could be connected to the first side wall 110 of the dial 100. For example, the first strap body 210 could be bonded to the first side wall 110 of the dial 100 by adhesion.

The second watch strap 300 may be connected to the second side wall 120 of the dial 100. In some embodiments, referring to FIGS. 5 and 6, the second watch strap 300 may include a second strap body 310 and a second mounting portion 320 connected to one end of the second strap body 310. The second mounting portion 320 could be inserted in the second mounting groove, so as to realize a detachable connection between the second watch strap 300 and the dial 100. For example, the second mounting portion 320 may be inserted in the second mounting groove and then could be locked in the mounting groove through a fastener such as a spring bar. It should be appreciated that, in other embodiments, the second mounting portion 320 could be omitted. In these cases, the second strap body 310 could be connected to the second side wall 120 of the dial 100. For example, the second strap body 310 may be bonded to the second side wall 120 of the dial 100 by adhesion.

Both the first watch strap 200 and the second watch strap 300 could be bent and deformed under external force. For example, the first watch strap 200 and the second watch strap 300 may both be flexible straps. In these cases, the materials of the first strap body 210 and the second strap body 310 may both be flexible materials. The flexible material may include, but be not limited to, at least one of silica gel, plastic, rubber, leather and fiber. The first watch strap 200 and the second watch strap 300 could be buckled with each other after being bent and deformed to form a ring-shaped receiving space, thus the wearable apparatus 10 could be worn to a joint such as a wrist of a human body.

In some embodiments, as shown in FIG. 3 and FIG. 4, the first watch strap 200 may include a confining strap 230 which may be called a bridge 230. The confining strap 230 is located between two opposite ends in a length direction of the first strap body 210. The confining strap 230 and the first strap body 210 may be integrally formed. For example, the confining strap 230 and the first strap body 210 could be integrally made by injection molding. A channel 240 could be defined between the confining strap 230 and the first strap body 210. In some embodiments, the channel 240 may extend along the length direction of the first watch strap 200. When the channel 240 is defined by the confining strap 230, the confining strap 230 may protrude from a side of the first strap body 210 facing away from the receiving space.

An end of the second strap body 310 away from the second mounting portion 320 could pass through the channel 240 from a side of the confining strap 230 away from the first mounting portion 220 and be fixed to the first strap body 210. In some embodiments, the first strap body 210 could define a catch groove or aperture 250, which is located between the first mounting portion 220 and the confining strap 230. That is, the catch groove 250 could be located in an extending direction of the channel 240. As shown in FIGS. 5 and 6, a buckle 350 may be provided on an end of the second strap body 310 away from the second mounting portion 320, and the end of the second strap body 310 provided with the buckle 350 could pass through the channel 240 from a side of the confining strap 230 away from the catch groove 250, so that the buckle 350 is engaged in the catch groove 250, thus the first watch strap 200 and the second watch strap 300 could be fastened to each other.

It should be appreciated that, in other embodiments, the buckle 350 could be provided on the first strap body 210 between the first mounting portion 220 and the confining strap 230, and the second strap body 310 could define a catch groove or aperture on an end away from the second mounting portion 320. It should be noted that, the amount of the above-mentioned catch grooves 250 may be more than one. For example, when multiple catch grooves 250 are defined in the first strap body 210, the multiple catch grooves 250 could be arranged at intervals along the length direction of the first watch strap 200. In these cases, the user could adjust the length of the second strap body 310 passing through the channel 240 according to the size of his/her wrist, so that the buckle 350 is engaged in the most suitable catch groove 250 to ensure that the user feels comfort after wearing the apparatus 10. Of course, in other embodiments, the multiple catch grooves 250 may also be defined in the second strap body 310.

In other embodiments, in addition to the buckle-connection between the buckle 350 and the catch groove 250, after an end of the second strap body 310 passes through the channel 240, the second strap body 310 may also be fixed to the first strap body 210 through magnetic attraction. For example, a first magnetic element may be embedded in the first strap body 210, and a second magnetic element may be embedded in the second strap body 310. The first magnetic element could be an electromagnet or a permanent magnet. The second magnetic element could be an electromagnet or a permanent magnet. The magnetic directions of the first magnetic element and the second magnetic element are opposite to each other. The second strap body 310 could be fixed to the first strap body 210 by magnetic attraction between the second magnetic element and the first magnetic element. In some embodiments, the first magnetic elements may be arranged at intervals along the length direction of the first watch strap 200. It should be noted that, one of the first magnetic element and the second magnetic element could be replaced by a metal piece.

In the above-mentioned wearable apparatus 10, an end of the second strap body 310 could pass through the channel 240 from the side of the confining strap 230 away from the catch groove 250, so that the buckle 350 is engaged in a catch groove 250 to realize the fixing connection between the first watch strap 200 and the second watch strap 300, thus the wearable apparatus 10 could be worn on a joint such as a wrist of the user. The confining strap 230 could force the portion of the second strap body 310 without the buckle 350 to attach the first strap body 210, to prevent the separation between part of the second strap body 310 and the first strap body 210. On the one hand, since the confining strap 230 is integrally formed with the first strap body 210, the processing of the first watch strap 200 could be facilitated, and the fabrication cost could be reduced. On the other hand, since the confining strap 230 could always be held at a fixed position on the first strap body 210 and could not slide with respect to the first strap body 210, the degree of attachment between the second strap body 310 and the first strap body 210 after the second strap body 310 passes through the channel 240 is increased, thus the user's experience is enhanced.

The confining strap 230 and the first strap body 210 could define the channel 240 in various ways.

In some embodiments, as shown in FIG. 7, the confining strap 230 may include a top edge portion 231 and side edge portions 232 connected to two opposite sides of the top edge portion 231. The top edge portion 231 is opposite to and spaced from the first strap body 210 in a thickness direction of the first strap body 210. The side edge portions 232 may be connected between the top edge portion 231 and the first strap body 210. The top edge portion 231, the side edge portions 232, and the first strap body 210 may collectively define the above-mentioned channel 240. In some embodiments, as shown in FIG. 8, the first strap body 210 may define a hole 2101 communicating with the channel 240. In this way, when the buckle 350 is detached from the catch groove 250 (for example, when the buckle 350 is not engaged firmly with the catch groove 250 and the buckle 350 is detached from the catch groove 250, or after the user wears the wearable apparatus 10 on a joint such as a wrist, the user's strenuous exercise may cause the buckle 350 to detach from the catch groove 250), the second strap body 310 would not be easily out from the confining strap 230 and separate from the first strap body 210. In other words, the wearable apparatus 10 would not be easily detached from the joint such as the wrist. This is because, during the process the second strap body 310 exiting from the confining strap 230, the second strap body 310 will press the buckle 350 to be engaged in the hole 2101 under the resistance of the top edge portion 231. Therefore, the hole 2101 could prevent the second strap body 310 with the buckle 350 from continuing to exit. On the other hand, the hole 2101 could also reduce material expense of the first watch strap 200 and decrease the manufacturing cost.

In some embodiments, when the second strap body 310 passes through the channel 240, the second strap body 310 could abut against the inner wall of the confining strap 230 and the confining strap 230 could be stretched. In other words, the cross-sectional area of the channel 240 defined by the confining strap 230 may be less than the cross-sectional area of the second strap body 310. In these cases, the confining strap 230 could accumulate elastic force. The confining strap 230 could wrap the second strap body 310 in the channel 240 with the elastic force. FIGS. 3 and 4 depict schematic structural diagrams of the first watch strap 200, wherein, the confining strap 230 of the first watch strap 200 is in a state when the confining strap 230 is being stretched after the second strap body 310 passes through the channel 240. After the second strap body 310 exits from the channel 240, as shown in FIG. 8, the confining strap 230 could collapse under the effect of the elastic force. It should be appreciated that, in other embodiments, the channel 240 defined between the confining strap 230 and the first strap body 210 could accommodate the second strap body 310. That is, the cross-sectional area of the channel 240 defined between the confining strap 230 and the first strap body 210 is larger than the cross-sectional area of the second strap body 310. When the first watch strap 200 and the second watch strap 300 mate with each other, the confining strap 230 does not need to be elastically deformed.

In some embodiments, the side edge portions 232 of the confining strap 230 may be omitted. In these cases, the confining strap 230 may include a top edge portion 231. As shown in FIG. 9, the top edge portion 231 could include a first segment 231a, a middle segment 231b and a second segment 231c connected in sequence along the width extension direction of the first watch strap 200. The first segment 231a and the second segment 231c may both be connected to the first strap body 210. It may also be appreciated that, the first segment 231a and the second segment 231c may both be extensions from the first strap body 210. The middle segment 231b could attach the first strap body 210. As shown in FIG. 10, the middle segment 231b could be upheld to be spaced apart from the first strap body 210 so as to define the above-mentioned channel 240. For example, after the second strap body 310 passes through the channel 240, the second strap body 310 could uphold the middle segment 231b. When the middle segment 231b is upheld, the middle segment 231b could accumulate elastic force. When the middle segment 231b releases the elastic force, the middle segment 231b could attach the first strap body 210 once again.

In some embodiments, as shown in FIG. 11, the first groove 2102 and the second groove 2103 spaced apart from each other are defined on the first strap body 210. The first groove 2102 and the second groove 2103 may both be along the width direction of the first strap body 210. The first groove 2102 may be closed in the circumferential direction. The second groove 2103 may be closed in the circumferential direction. A portion between the first groove 2102 and the second groove 2103 may form the confining strap 230. The confining strap 230 could be upheld to define a channel 240. One port of the channel 240 may be an opening of the first groove 2102 and the other port of the channel 240 may be an opening of the second groove 2103. When the confining strap 230 is upheld, the confining strap 230 could accumulate the elastic force. When the confining strap 230 releases the elastic force, the confining strap 230 could collapse. An outer face of the collapsed confining strap 230 may be flush with an outer face of the first strap body 210. In some embodiments, the first groove 2102 and the second groove 2103 may also be scribed lines. In these cases, when the confining strap 230 is in a state of not being upheld, that is, the first watch strap 200 does not mate with the second watch strap 300, sides of the confining strap 230 adjacent to the first groove 2102 and the second groove 2103 could be in contact with the first strap body 210, and the outer face of the confining strap 230 could be flush with the outer face of the first strap body 210.

Another aspect of the present disclosure provides a watch strap. The watch strap may include a first strap body 210 and a confining strap 230. The confining strap 230 could be integrally formed with the first strap body 210. The confining strap 230 could be located between two opposite ends in a length direction of the first strap body 210, and a channel 240 could be defined between the confining strap 230 and the first strap body 210. The channel 240 extends along the length direction of the watch strap. It should be noted that, the strap of the embodiments of the present disclosure could be produced separately and applied to the wearable apparatus 10, and the structural characteristics of the strap could be exactly the same as those of the first watch strap 200 in the embodiments of the present disclosure, and are thus not detailed hereafter.

The technical features of the embodiments described above could be arbitrarily combined. For the sake of brevity, all the possible combinations of the technical features are not enumerated and described. However, as long as there is no contradiction in the combination of these technical features, it should be considered within the scope described in this specification.

The above-mentioned embodiments only express several implementations of the present disclosure, whose descriptions are specific and detailed, but could be construed as a limitation on the patent scope of the present disclosure. It should be noted that, for those of ordinary skill in the art, several modifications and improvements could be made without departing from the concept of the present disclosure, which all belong to the protection scope of the present disclosure. Therefore, the protection scope of this disclosure shall be subject to the appended claims.
