In the present embodiment, as shown in fig. 1 and 2 in conjunction, the main body 1 is used for information display such as display of clock information; the wrist strap 2 is used for realizing the wearing and fixing of the main body 1 on the wrist of a human body; taking the wrist-worn device as an intelligent watch as an example, the main body 1 can be a watch face, and the wrist strap 2 can be a watchband. The main body 1 has two end portions, each end portion of the main body 1 is provided with a first connecting portion 11, the first connecting portion 11 can be in an integral structure with the outer shell of the main body 1, the material of the first connecting portion 11 can be the same as or different from that of the outer shell of the main body 1, for example, the outer shell of the main body 1 can be made of plastic, and the first connecting portion 11 is made of silica gel; for another example, the material of the main body 1 and the material of the first connecting portion 11 are both plastic materials. The wrist strap 2 can be an integrated belt-shaped structure, two ends of the wrist strap 2 are respectively connected with two ends of the main body 1 through a connecting structure, and the wrist strap 2 is sleeved on the wrist of a user to realize wearing of the wrist wearing equipment; the wrist band 2 may also include two independent band structures respectively connected to both ends of the main body 1 by connection structures, and the ends of the two independent band structures far from the main body 1 are connected by a buckle structure to implement wearing of the wrist-worn device. The wrist strap 2 has a second connecting portion 21, the second connecting portion 21 may be made of the same material as the wrist strap 2, for example, the wrist strap 2 may be a silicone band with an integrated structure; or, the second connecting portion 21 and the wrist strap 2 are made of different materials, for example, the wrist strap 2 is made of silica gel, the second connecting portion 21 is made of plastic, and the second connecting portion 21 and the wrist strap 2 are integrally formed through two-color injection molding and other processes.

As shown in fig. 3 and 4, at least one of the first connecting portion 11 and the second connecting portion 21 is made of a flexible material, such as silicone rubber, TPU (Thermoplastic polyurethane elastomer rubber), or the like. Thus, at least one of the first connecting portion 11 and the second connecting portion 21 can be deformed when being pressed, so that the distance between the male buckles 22 or the distance between the female grooves 1a can be correspondingly reduced or increased along with the deformation, and the male buckles 22 can be clamped or separated from the corresponding female grooves 1 a. Specifically, each of the female slots 1a in the present embodiment includes a first slot segment 1a1 and a second slot segment 1a2 that are communicated with each other, and a direction in which the center of the first slot segment 1a1 faces the center of the second slot segment 1a2 is defined as an extending direction of the female slot 1a (as indicated by a dotted arrow in fig. 4). In two female slots 1a with different extending directions, the distance between the first slot segments 1a1 of the two female slots 1a is different from the distance between the second slot segments 1a2 of the two female slots 1a, so that when two male buckles 22 matched with the two female slots 1a slide into the second slot segments 1a2 of the two female slots 1a through the first slot segments 1a1 of the two female slots 1a, respectively, if the distance between the two male buckles 22 is not changed, the distance between the two female slots 1a needs to be changed correspondingly; if the distance between the two female slots 1a is not changed, the distance between the two male buckles 22 needs to be changed accordingly. Since at least one of the first connection section and the second connection section is made of a flexible material, the distance between the two male buckles 22 can be changed by disposing the two male buckles 22 on the flexible material and then deforming the flexible material under pressure; the distance between the two female grooves 1a can be changed by arranging the two female grooves 1a on a flexible material and then pressing and deforming the flexible material; can also set up on flexible material through one of them pin thread 22 and a female groove 1a, let pin thread 22 and the female groove 1a interval before change on the flexible material when making the flexible material deformation of extrusion, realize the joint or break away from of these two pin threads 22 and two female grooves 1 a.

In practical applications, for example, two female slots 1a with different extending directions are simultaneously disposed on the first connecting portion 11, two male buckles 22 matched with the two female slots 1a are simultaneously disposed on the second connecting portion 21, and the second connecting portion 21 is made of a flexible material. The distance between the two male snap fasteners 22 can be designed to be equal to the distance between the second groove segments 1a2 of the two female grooves 1a, because the two female grooves 1a extend in different directions, and therefore the distance between the first groove segments 1a1 of the two female grooves 1a is not equal to the distance between the second groove segments 1a2 of the two female grooves 1a, and here, for example, the distance between the second groove segments 1a2 of the two female grooves 1a is greater than the distance between the first groove segments 1a1 of the two female grooves 1 a. The distance between the two male buckles 22 can be designed to be equal to the distance between the two second groove sections 1a2, when the wrist band 2 is assembled on the main body 1, the user squeezes and twists the second connecting portion 21 made of flexible material to deform the second connecting portion 21, and the distance between the two male buckles 22 on the second connecting portion 21 is reduced, and at this time, partial structures of the two male buckles 22 can respectively extend into the first groove sections 1a1 of the two female grooves 1 a. Afterwards, the user can remove the extrusion to second connecting portion 21, let the second connecting portion 21 of flexible material can elastic recovery and drive two pin buckles 22 and keep away from each other, distance between two pin buckles 22 increases gradually, two pin buckles 22's partial structure respectively along two first groove section 1a1 slide in corresponding second groove section 1a2, and be spacing respectively between two flange 111 and two second groove section 1a 2's diapire, it is fixed with two female joint of groove 1 a's joint to realize two buckles. When dismantling wrist strap 2 from main part 1, the user extrudees once more and twists the second connecting portion 21 of flexible material, makes the deformation of second connecting portion 21 drive two pin buckles 22 and is close to each other, and the interval between two pin buckles 22 diminishes gradually, and two pin buckles 22 can be respectively along two second groove section 1a2 in the corresponding first groove section 1a1 of sliding in, realize breaking away from of two buckles and two female grooves 1 a.

In the embodiment, because the extending directions of at least two female slots 1a are different, the sliding directions of the male snap 22 engaged with the female slots 1a with different extending directions are different when the male snap is assembled with the female slots 1a or disassembled from the female slots 1 a. Thus, even when the wristband 2 moves in a single direction due to a collision error, the wristband 2 does not slip off the main body 1, and the reliability of the wristband 2 being fixed to the main body 1 can be ensured. The connecting structure of the wrist strap 2 and the main body 1 of the wrist-wearing device only comprises at least two connecting assemblies, each connecting assembly only comprises the matched male buckle 22 and the matched female groove 1a, the connecting structure between the main body 1 and the wrist strap 2 of the wrist-wearing device is greatly simplified, and the manufacturing cost of the wrist-wearing device can be effectively reduced.

In an embodiment of the present invention, as shown in fig. 5 and 6, the male buckle 22 includes a rod part 221 and a cap part 222, and a part of the structure of the cap part 222 protrudes from the peripheral wall of the rod part 221; when the male buckle 22 is connected with the female slot 1a, each rod part 221 passes through the notch of a second slot section 1a2 and extends into the second slot section 1a2, and the cap part 222 is limited between a flange 111 and the bottom wall of a second slot section 1a 2; and/or the maximum width of the notches of the first slot segment 1a1 is greater than the maximum width of the notches of the second slot segment 1a 2.

In this embodiment, the stem portion 221 and the cap portion 222 of the male buckle 22 can be integrally formed, and the material thereof can be the same material, such as plastic, silicone, etc. The rib 111 is disposed along the inner peripheral wall of the second groove segment 1a2, and the rib 111 is a protruding structure on the side wall of the second groove segment 1a2, and the extending shape thereof may be U-shaped. When the wrist strap 2 is assembled with the main body 1, the cap portion 222 of the male buckle 22 extends into the first groove section 1a1 of the female groove 1a, the rod portion 221 slides along the first groove section 1a1 and slides into the second groove section 1a2 through the communication position of the first groove section 1a1 and the second groove section 1a2, the rod portion 221 passes through the notch of the second groove section 1a2, the cap portion 222 is limited between the flange 111 and the bottom wall of the second groove section 1a2, and the male buckle 22 is clamped with the female groove 1 a. Wherein the shape of the cap portion 222 may be square, circular, etc., and the shape and size of the first groove segment 1a1 is matched to the shape and size of the cap portion 222, so that the cap portion 222 can pass through the notch of the first groove segment 1a1 and extend into the first groove segment 1a 1.

The inner peripheral wall of the first groove section 1a1 may be an arc surface, and the second groove section 1a2 may be a strip-shaped groove, because when the shape and size of the notch of the first groove section 1a1 match the shape and size of the cap 222, the grooved area of the first groove section 1a1 is smaller, and the number of the hollow-out portions on the first connection portion 11 is smaller, so that the structural strength of the first connection portion 11 and the reliability of connection between the first connection portion 11 and the second connection portion 21 can be ensured. Therefore, when the maximum width of the notch of the first groove section 1a1 is greater than the maximum width of the notch of the second groove section 1a2, the grooving area of the second groove section 1a2 can be effectively reduced, thereby reducing the grooving area of the entire female groove 1a to secure the structural strength of the second connection part 21 and the reliability of the connection of the first connection part 11 with the second connection part 21.

In an embodiment of the present invention, as shown in fig. 4, 6 and 7, an included angle between the extending direction of one of the mother grooves 1a and the extending direction of at least one other mother groove 1a is greater than or equal to 90 degrees and less than or equal to 180 degrees.

In this embodiment, since the extending directions of the at least two female grooves 1a are different, when the wrist strap 2 is detached from the main body 1, the male buckle 22 engaged with the female grooves 1a having different extending directions needs to slide in different directions to detach the wrist strap 2 from the main body 1, so as to prevent the wrist strap 2 from easily slipping off the main body 1 when the wrist strap 2 is touched by mistake and slides in one direction. Because the similarity of the sliding directions of the male buckles 22 engaged with the two female grooves 1a is higher when the included angle between the extending directions of the two female grooves 1a with different extending directions is greater than 0 degree and less than 90 degrees, for example, when the included angle between the extending directions of the two female grooves 1a is 45 degrees and extends toward the left direction shown in fig. 6, the two corresponding male buckles 22 can be slid and separated by sliding to the left side of the main body 1 shown in fig. 6, and when the wrist strap 2 slides to the left direction shown in fig. 6 due to a miss-collision with respect to the main body 1, the wrist strap 2 may still slip off the main body 1. Therefore, the present embodiment further provides the female slots 1a different in extension direction such that there are two female slots 1a among them: an included angle formed by the extending direction of one female slot 1a and the extending direction of the other female slot 1a is greater than or equal to 90 degrees and less than or equal to 180 degrees, so that the male buckle 22 engaged with the two female slots 1a must slide towards two opposite sides of the main body 1 (such as the left side and the right side of the main body 1 shown in fig. 6) at the same time to realize the separation from the two female slots 1a, and such irregular sliding cannot occur in the normal wearing process of the wrist-wearing device, so that the reliability of the connection of the wrist strap 2 and the main body 1 can be further improved.

Optionally, as shown in fig. 6, an included angle formed between the extending direction of one female slot 1a and the extending direction of the other female slot 1a is 90 degrees, and the sliding disengagement direction of the male buckle 22 snap-fitted into the two female slots 1a is also 90 degrees, so that the wrist strap 2 does not move in the horizontal and vertical directions relative to the main body 1 during normal wearing of the wrist strap 2 device, and therefore, the structural arrangement of the female slots 1a can ensure the reliability of the connection between the wrist strap 2 and the main body 1.

Optionally, as shown in fig. 7, the two female grooves 1a extend in the same direction, an included angle formed between the extending direction of one female groove 1a and the extending direction of the two female grooves 1a is 180 degrees, and the sliding direction of the male buckle 22 snap-fitted into the two female grooves 1a extending in 180 degrees is also 180 degrees, so that the movement of the wrist strap 2 relative to the main body 1 in two opposite directions does not occur simultaneously during the normal wearing process of the wrist strap 2 device, and therefore, the structural arrangement of the female grooves 1a can ensure the reliability of the connection of the wrist strap 2 with the main body 1.

In an embodiment of the present invention, as shown in fig. 2, 3 and 5, the connecting structure includes two connecting components, the female slots 1a of the two connecting components are disposed on the first connecting portion 11, and the male buckles 22 of the two connecting components are disposed on the second connecting portion 21.

In the present embodiment, only two female grooves 1a are formed in the first connecting portion 11, and the extending directions of the two female grooves 1a are made different; the two male buckles 22 are correspondingly arranged on the second connecting part 21, so that the number of the grooves of the female groove 1a and the number of the male buckles 22 can be reduced as much as possible on the basis of ensuring the connection reliability of the first connecting part 11 and the second connecting part 21, the area of the hollowed-out part on the first connecting part 11 is favorably reduced, the structural strength of the first connecting part 11 is ensured, and the connection reliability of the first connecting part 11 and the second connecting part 21 is further ensured; meanwhile, the material cost of the male buckle 22 can be reduced, so that the material cost of the wrist strap 2 equipment is reduced. In addition, because the two male buckles 22 are disposed on the second connecting portion 21 of the wrist band 2, it is also convenient for the user to hold the wrist band 2 and mount it on the main body 1, rather than holding the main body 1 and mount it on the wrist band 2, so that the main body 1 held and pressed is not the main body 1, and the main body 1 can be protected.

Alternatively, the two male buckles 22 of the present embodiment are disposed in a staggered manner, and the first groove segments 1a1 of the two female grooves 1a are disposed in a staggered manner. When pin thread 22 and second groove section 1a2 joint cooperation, two pin thread 22 are located two second groove sections 1a2 respectively, take the setting mode of the pin thread 22 that fig. 5 shows as an example, two pin thread 22 all misplace at vertical direction and horizontal direction, so, even two female groove 1 a's extending direction is different, still can guarantee the edge of first connecting portion 11 and the edge alignment of second connecting portion 21 when pin thread 22 and second groove section 1a2 joint, appear crooked when avoiding wrist strap 2 and main part 1 assembly, aesthetic property when guaranteeing wrist strap 2 and main part 1 assembly and the good wearing experience of this wrist strap 2 equipment.

Optionally, the male buckle 22 and the second connecting portion 21 in this embodiment are integrally formed; and/or the second connecting part 21 is made of a flexible material, and the male buckle 22 is made of a rigid material.

Through the limit matching of the limit groove and the first bump 113, on one hand, the gap between the first assembling surface 112 and the second assembling surface 211 generated by the spacer of the first bump 113 can be reduced or eliminated, so that the wrist strap 2 is assembled with the main body 1 seamlessly, and the attractiveness and wearing experience of the wrist strap 2 equipment are improved; on the other hand, the inner peripheral wall of the limiting groove can better stop the movement of the first bump 113, so that the first connecting part 11 is difficult to slide relative to the second connecting part 21, the wrist strap 2 is difficult to slide relative to the main body 1 and break away from the main body 1, and the reliability of assembling the wrist strap 2 and the main body 1 can be improved.

Optionally, the other of the first and second mounting faces 112 and 211 is provided with a plurality of second protrusions 212; when the male buckle 22 is connected to the female slot 1a, the outer sidewall of each first protrusion 113 abuts against and limits the outer sidewall of a second protrusion 212. Therefore, under the limit of the mutual stopping of the first protrusion 113 and the second protrusion 212, the first connecting part 11 can be effectively prevented from sliding relative to the second connecting part 21, so that the wrist strap 2 is less likely to slide relative to the main body 1 and be separated from the main body 1, and the reliability of assembling the wrist strap 2 with the main body 1 can be improved.

Optionally, one of the first and second mounting faces 112 and 211 is provided with a surrounding block 114; when the male snap 22 is connected to the female groove 1a, the surrounding block 114 is located on the outer periphery of each first projection 113 and abuts against the other of the first fitting surface 112 and the second fitting surface 211. The surrounding block 114 can be arranged along the edge of the first assembling surface 112 or the second assembling surface 211, so that the surrounding block 114 can shield the gap between the first connecting part 11 and the second connecting part 21 due to the spacer of the first bump 113, and the first bump 113 is invisible to the user, thereby realizing the hidden design of the first bump 113 and the seamless connection design of the wrist strap 2 and the main body 1, and improving the aesthetic property and wearing experience of the wrist strap 2 device. The shape of the surrounding block 114 may be square, annular, etc., the surrounding block 114 may be made of silicon rubber, rubber lamp elastic material, and the thickness of the surrounding block 114 may be larger than the thickness of the first protrusion 113, so that the surrounding block 114 can shield each first protrusion 113 when the wrist band 2 is connected with the main body 1.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
