The connecting member 231 is used for being buckled with the buckling member 233 to fix the positions of the first strap 210 and the second strap 220 relatively, so as to form the accommodating space 11 with a proper size.

Further, referring to fig. 2, in the present embodiment, after the fastening member 233 is fastened to the connecting member 231, the fastening member 233 is stacked on a side of the first strap 210 facing away from the electronic device 100. In other words, when the end of the first strap 210 away from the electronic device 100 is regarded as the free end of the first strap 210, the free end is at least partially covered by the second strap 220, and the second strap 220 can abut and restrain the free end of the first strap 210, so that the free end of the first strap 210 can be reliably attached to the second strap 220. In such an embodiment, the second strap 220 does not need to be provided with a band that slides along the second strap 220 for fixing the free end of the first strap 210, so that the strap assembly 200 can have a more concise appearance characteristic.

In some embodiments, the length of first strap 210 is greater than the length of second strap 220 in a flattened state. The material of the first strap 210 and the second strap 220 may be the same, for example, the material of the first strap 210 and the material of the second strap 220 may both be soft rubber, so that the first strap 210 and the second strap 220 have the characteristics of softness and easy deformation. In other embodiments, the first strap 210 and the second strap 220 may be made of leather, synthetic leather, or woven canvas, and the first strap 210 and the second strap 220 may also have flexibility and easy deformation. Of course, in other embodiments, the material of first strap 210 and second strap 220 may be different, and the flattened length of first strap 210 may be equal to or less than the flattened length of second strap 220.

Referring to fig. 6 and 7, the connecting member 231 includes a connecting portion 2311 and a fastening portion 2313 connected to the connecting portion 2311, the connecting portion 2311 can be used for connecting the first strap 210, and the fastening portion 2313 is used for fastening to the fastening member 233. Referring to fig. 8 and 9, the snap member 233 includes a housing 2331 and a button 2333 provided on the housing 2331, the housing 2331 can be used to connect the second strap 220, and the housing 2331 is provided with a groove 233 a. The fastening portion 2313 is adapted to extend into the groove 233a and fasten with the button 2333, so that the position of the second strap 220 is fixed relative to the position of the first strap 210. After the fastener 233 is fastened to the connector 231, the user can press the button 2333, so that the button 2333 moves relative to the housing 2331, and the connector 231 can be separated from the fastener 233, thereby separating the first strap 210 from the second strap 220, and facilitating the user to take off the wearable device 10.

Referring to fig. 9, the strap assembly 200 may further include a clip 250. referring to fig. 5, the clip 250 is inserted through the second strap 220 and the housing 2331 in the width direction of the second strap 220, so that the second strap 220 can rotate relative to the housing 2331. Specifically, in this embodiment, the housing 2331 may be provided with a lug, the lug is provided with a hole for passing the clip needle 250, and the clip needle 250 may be a structure with two ends capable of elastically stretching. In the process of assembling the second strap 220 and the fastener 233, the fastening pin 250 may be first inserted into the end of the second strap 220 away from the electronic device 100, and then the fastening pin 250 is inserted into the hole of the lug, so as to realize the rotational fit between the second strap 220 and the fastener 233. The rotating fit structure of the first strap 210 and the fastener 233 can facilitate the user to adjust the angle of the latch 230, so that the user can conveniently fasten the connector 231 to the fastener 233, thereby improving the wearing convenience. Of course, the latch 250 is not required. For example, the second strap 220 can be fixedly attached to the housing 2331 of the clasp 233.

With reference to fig. 5, the first strap 210 has a plurality of spaced fastening holes 210a along the length direction thereof, for example, the number of the fastening holes 210a may be more than two. Referring to fig. 6 and 7, the connection portion 2311 includes a body a1 and a catch a2 connected to the body a1, and the buckling portion 2313 and the catch a2 protrude from opposite sides of the body a1, respectively. Further, the catching portion 2313 is spaced apart from the catch a 2. The plurality of catching holes 210a of the first strap 210 may be used to adjust the position of the link 231 in the first strap 210, and the catch a2 may be used to catch into any one of the catching holes 210a to fix the position of the link 231 relative to the position of the first strap 210. It is to be understood that the length direction of the first strap 210 may be simply understood as the extending direction of the length of the first strap 210 in the flattened state, but the length direction of the first strap 210 may still be visually perceived in the non-flattened state.

Further, the body a1 may form a mounting hole 231a on a side away from the fastening portion 2313, and the mounting hole 231a is used for passing through the first strap 210. The mounting hole 231a may be circumferentially closed so that the first strap 210 can be stably and reliably fixed to the connecting member 231. Further, the fastening portions 2313 may be provided corresponding to the mounting holes 231 a. Body a1 may be curved in an arc to accommodate the curvature of first strap 210 and to enable body a1 to better conform to first strap 210. In the present embodiment, with reference to the length direction of the first strap 210, when the connector 231 is connected to the first strap 210, the mounting hole 231a extends along the length direction of the first strap 210, and the fastening portion 2313 protrudes from the side of the body a1 away from the electronic device 100 in the process of bending the first strap 210 and forming the accommodating space 11. The body a1 corresponding to the mounting hole 231a may have a relatively large length, and the fastening portion 2313 is disposed on a side of the body a1 facing away from the mounting hole 231 a. When the connector 231 is connected to the first strap 210, an orthogonal projection of the fastening portion 2313 in the longitudinal direction of the first strap 210 at least partially overlaps an orthogonal projection of the body a1 in which the mounting hole 231a is located in the longitudinal direction of the first strap 210. When the connecting member 231 is connected to the first strap 210, the above structure can prevent the connecting member 231 from rotating at an excessive angle relative to the first strap 210 by using the fastening portion 2313 as a fulcrum due to bending of the first strap 210, so that the connection reliability between the connecting member 231 and the first strap 210 can be improved, the fastening reliability between the connecting member 231 and the fastening member 233 can be improved, and the fastening portion 2313 can be prevented from easily coming off the fastening member 233.

Referring to fig. 5, during the first wearing of the wearable device 10 by the user, the free end of the first strap 210 may be inserted into the mounting hole 231a of the connector 231, and the size of the accommodating space 11 is adjusted to fit the size of the wrist of the user, so as to clip the clip a2 of the connector 231 into the proper clip hole 210 a. In the wearing process later, since the connector 231 does not need to be detached from the first strap 210, the wearing convenience can be improved. Further, for the same user, after the connecting member 231 is first snapped into the snap hole 210a of the first strap 210, the snap a2 does not frequently enter and exit the snap hole 210a any more during the wearing process, so that the second strap 220 can be prevented from being deformed or worn due to frequent wearing, and the service life of the strap assembly 200 can be prolonged. Further, the connector 231, the button 2333, and the housing 2331 may be made of a metal material, such as stainless steel, to improve the service life of the latch 230 and the appearance of the wearable device 10.

Referring to fig. 6, the fastening portion 2313 is provided with a receiving groove 231b, and the receiving groove 231b may be a through groove, that is, the receiving groove 231b may be communicated with the mounting hole 231 a. The receiving slot 231b may also be a blind slot, that is, the receiving slot 231b and the mounting hole 231a are separated by the body a 1. In the present embodiment, the outer profile of the cross section of the engagement portion 2313 is substantially rectangular, and the accommodation groove 231b is circumferentially closed. In other embodiments, the outer profile of the cross-section of the snap 2313 may be circular or elliptical or triangular or other shapes. Referring to fig. 8, the shape of the cross section of the groove 233a matches the shape of the cross section of the fastening portion 2313, and the groove 233a may also be circumferentially closed, so that the fastening portion 2313 and the groove 233a may form a clearance fit or a transition fit, and the fastening state of the fastening portion 2313 in the fastening member 233 is relatively stable. Of course, such an arrangement is not necessary. For example, the cross-sectional shape of the groove 233a is rectangular, the cross-sectional shape of the engagement portion 2313 is circular, and the engagement portion 2313 can be inserted into the groove 233 a.

Referring to fig. 9, button 2333 includes a main body B1 and a retaining end B2 connected to main body B1, retaining end B2 being received in recess 233a of housing 2331. The body B1 is exposed to the housing 2331 and is intended to be pressed to enable the keys 2333 to move relative to the housing 2331. Referring to fig. 6, in the process that the fastening portion 2313 extends into the groove 233a, the fastening portion 2313 is used for driving the button 2333 to move relative to the housing 2331, so that the holding end B2 enters the receiving groove 231B of the fastening portion 2313 and is fastened with the fastening portion 2313. Further, in this embodiment, in the process that the buckling portion 2313 extends into the groove 233a, the buckling portion 2313 abuts against the holding end B2 and drives the button 2333 to move towards the housing 2331 so that the buckling portion 2313 can be buckled with the button 2333. The fastening portion 2313 may be provided with a through hole 231c communicating with the receiving groove 231B, and the fastening end B2 may at least partially extend into the through hole 231c when the fastening end B2 is fastened with the fastening portion 2313. The through hole 231c is provided to facilitate the processing of the fastening portion 2313, for example, the through hole 231c may be directly milled from the outer side of the fastening portion 2313 and formed to be fastened with the button 2333, and a T-shaped milling cutter is not used to process a structure for fastening with the button 2333 from the inner side of the accommodating groove 231 b. Of course, the provision of the through hole 231c is not essential. For example, when the engaging portion 2313 is formed by welding, a structure for engaging with the button 2333 may be processed in advance to avoid complicated processing.

Further, referring to fig. 9, the fastener 233 includes a reset member 2335 connected to the housing 2331 and the button 2333, and after the holding end B2 enters the receiving slot 231B, the reset member 2335 is used for driving the button 2333 to move relative to the housing 2331 so that the holding end B2 enters the through hole 231 c. In this embodiment, the reset member 2335 is an elastic member, for example, the reset member 2335 may be a spring, a leaf spring, an elastic column, or the like. With reference to fig. 10, 11 and 12, during the process of the latch 2313 entering the groove 233a, the latch 2313 drives the button 2333 to move toward the housing 2331 and compress the elastic member, and the elastic member accumulates elastic potential energy; referring to fig. 13, after the catching end B2 extends into the receiving groove 231B to a certain depth, the elastic member releases the elastic potential energy to drive the button 2333 to move outward of the housing 2331 and make the catching end B2 enter the through hole 231c to be buckled with the buckling part 2313. Referring to fig. 14, in some embodiments, when the user presses the fastening portion 2313 into the groove 233a to a depth of about 0.6 mm, the button 2333 is reset by the reset piece 2335, so that the fastening portion 2313 is fastened to the button 2333.

In other embodiments, the installation position of the elastic member on the housing 2331 is changed, so that the elastic member is stretched during the process that the fastening portion 2313 extends into the groove 233 a; after the holding end B2 extends into the receiving groove 231B by a certain depth, the elastic potential energy of the elastic member can drive the button 2333 to move outward of the housing 2331, thereby achieving the mutual fastening of the fastening portion 2313 and the fastening member 233. In other embodiments, a magnetic member may be used instead of the elastic member, and the key 2333 may be reset by using the principle that like magnetic poles repel and unlike magnetic poles attract, so that the key 2333 and the engagement portion 2313 can be engaged with each other.

Further, referring to fig. 9, the button 2333 may have a waist-shaped hole B3, the fastener 233 includes a limiting member 2337 passing through the waist-shaped hole B3, and the limiting member 2337 is fixedly connected to the housing 2331 to limit the moving range of the button 2333 relative to the housing 2331. Specifically, the two ends of the waist-shaped hole B3 may correspond to the two extreme positions of the key 2333. For example, when the user presses the button 2333 to move the button 2333 into the housing 2331, the outer end of the waist-shaped hole B3 can abut against the stopper 2337 to stop the movement of the button 2333; when the reset 2335 actuates the key 2333 to move out of the housing 2331, the opposite end of the slot B3 can abut against the stop 2337 to stop the movement of the key 2333. The limiting member 2337 may be a screw, a bolt or a rivet, so that the assembly of the limiting member 2337, the reset member 2335 and the housing 2331 is convenient. For example, after the elastic member, the button 2333 and the housing 2331 are assembled, the limiting member 2337 is inserted into the housing 2331 and passes through the waist-shaped hole B3, so that the elastic member, the button 2333 and the housing 2331 can be assembled.

In the present embodiment, the housing 2331 is provided with buttons 2333 at both ends of the second strap 220 in the width direction. When the user takes off the wearable device 10 from the wrist, the user can use two fingers to clamp the buttons 2333 on both sides of the fastener 233, and press the buttons 2333 on both sides to move the buttons 2333 into the housing 2331, so that the clamping end B2 of the button 2333 can be withdrawn from the through hole 231c, and at this time, the user can pull the first strap 210 with a small force to make the fastening portion 2313 on the first strap 210 come out of the groove 233a of the fastener 233, thereby separating the first strap 210 from the second strap 220, and further enabling the wearable device 10 to be taken off from the wrist. Of course, in other embodiments, only one key 2333 may be provided.

With continued reference to fig. 13, the latching portion 2313 is provided with a first engagement surface C1. in some embodiments, the first engagement surface C1 may be a plane and form an acute angle with the moving direction of the button 2333 relative to the housing 2331. During the process of the protrusion 2313 extending into the groove 233a, the first engagement surface C1 abuts against the latching end B2 and drives the button 2333 to move. In the process of pressing the buckling portion 2313 into the groove 233a, the force applied to the button 2333 by the first mating surface C1 in the above structure can be decomposed into a component force directed toward the inner side of the housing 2331 along the width direction of the second strap 220, and the component force can drive the button 2333 to move toward the housing 2331, so that the button 2333 can press the reset piece 2335 to realize the mutual buckling of the buckling portion 2313 and the buckling piece 233. In other embodiments, the first engagement surface C1 can be an arc surface, and the first engagement surface C1 of the arc structure can also abut against the holding end B2 and drive the button 2333 to move during the process of the engaging portion 2313 extending into the groove 233 a.

Further, the holding end B2 has a second engagement surface B21, and in some embodiments, the second engagement surface B21 is a plane and forms an acute angle with the moving direction of the key 2333 relative to the housing 2331. In the process of pressing the buckling portion 2313 into the groove 233a, the acting force of the buckling portion 2313 on the second mating surface B21 can be decomposed into a component force which is directed toward the inner side of the housing 2331 along the width direction of the second strap 220, and the component force can drive the button 2333 to move toward the housing 2331, so that the button 2333 can press the reset piece 2335 to realize the mutual buckling of the buckling portion 2313 and the buckling piece 233. In this embodiment, the first engagement surface C1 and the second engagement surface B21 both form an angle of 45 degrees with the moving direction of the button 2333 relative to the housing 2331, so that the button 2333 and the fastening portion 2313 have better stress characteristics and the button 2333 and the fastening portion 2313 are prevented from self-locking. In other embodiments, the second engagement surface B21 may be an arc surface, and the second engagement surface B21 of the arc structure can also abut against the buckling portion 2313 and be driven by the buckling portion 2313 to move the key 2333 relative to the housing 2331. Of course, it is understood that the first mating surface C1 and the second mating surface B21 need not be provided at the same time, and at least one of the two mating surfaces is present to enable the latch 2313 to actuate the button 2333 to move relative to the housing 2331.
