The utility model provides a wrist-worn device, referring to fig. 1 and 4, the wrist-worn device generally includes a wrist band 100 and a device main body 200, one end of the wrist band 100 is connected with one end of the device main body 200, and the other end is a free end, the device main body 200 may be a watch body (for example, a common watch dial, an intelligent watch dial, or a bracelet main body), or a health monitoring module (generally, a watch body with a non-screen display function, for example, a monitoring sensor for monitoring a heart rate, a blood pressure, and the like of a user, or a sensor for monitoring a motion state, a walking step number, and the like). In the present invention, the wristband 100 has an arc-shaped wearing state, and the wearing state thereof is naturally maintained, that is, the wristband 100 maintains the arc-shaped wearing state even in a non-wearing state. Without loss of generality, in an embodiment of the present invention, the wrist bands 100 are generally provided in two, and the apparatus body 200 is connected between the two wrist bands 100; of course, in other embodiments, only one of the wristbands 100 may be provided and have a curved shape, as will be further described below.

The worn state of the wristband 100 in the present invention is that the wristband 100 has only one form in a natural state, that is, the wristband 100 is only naturally maintained in an arc state, which is different from a papa ring, and a papa ring can have two forms in a natural state, one is a straight strip form, and the other is an arc (ring) form, and a papa ring in the straight strip form can be converted into the arc (ring) form after the papa ring is used to flap the wrist, so as to implement wearing. It should be noted that, the wrist band 100 of the present invention is "maintained in the arc state naturally" and not limited to the deformation capability of the wrist band 100, at least, the free end of the wrist band 100 can be deformed and opened outwards under the action of external force, so that the user can wear or remove the wrist device on or from the wrist, and when the external force disappears, the deformation of the wrist band 100 can be recovered to the arc wearing state.

Referring to fig. 1 and 2, in an embodiment of the present invention, the wristband 100 includes a wristband portion 100 and a memory metal portion 120 disposed on the wristband portion 110, wherein one end of the wristband portion 110 is configured to be connected to one end of the device main body 200, and the other end is a free end, and the memory metal portion 120 has a memory state of being arc-shaped in a natural state, so that the wristband portion 110 is naturally maintained in an arc-shaped state, and the wristband 100 is naturally maintained in a wearing state, so that, on one hand, a wristband buckle and its related connecting structure can be saved, thereby saving material cost and assembly cost; on the other hand user need not to carry out the counterpoint lock joint of wrist band buckle when wearing, and the user need not to unbuckle just can excise wrist strap 100, enables the user and can wear the equipment with the wrist convenient and fast ground or excise in the wrist to promote user's use and experience.

It will be appreciated that the memory metal is superelastic, in that under an external force, the memory metal has a much greater deformation recovery capacity than the normal metal, i.e. the large strain generated during loading (e.g. during wearing/removal) is relieved with unloading, thereby returning to the (arcuate) memory shape.

In one embodiment, two wristbands 100 are disposed in one device body 200, one end of the band body 110 of one wristband 100 is connected to one end of the device body 200, one end of the band body 110 of the other wristband 100 is connected to the other end of the device body 200, and the two wristbands 100 together enclose a wearing space of the wrist-worn device. Alternatively, referring to fig. 3, the free ends of the wrist bands 100 are close to each other but not in contact, that is, there is a gap between the free ends of the band bodies 110, in which case, the user opens or stretches the wrist bands 100 so that the opening between the wrist bands 100 can be accessed by the wrist, and the wrist-worn device can be conveniently and quickly worn on or removed from the wrist. However, the design is not limited thereto, and in other embodiments, in the wearing state, the free ends of the two band portions 110 are stacked (see fig. 1); in other embodiments, the free ends of the two belt body portions 110 can be shifted and parallel; in other embodiments, the free ends of the two belt body portions 110 can be butted.

Further alternatively, when two wristbands 100 are provided, the radian of the band body 110 of each wristband 100 is smaller than pi, that is, the band body 110 of each wristband 100 is provided in a minor arc; it can be understood that, due to the presence of the device body 200, the two wrist bands 100 can enclose a shape stably surrounding the wrist of the user without an arc of pi, so that the wearing stability is ensured and the material of the wrist bands 100 is saved, thereby reducing the material cost. However, the design is not limited thereto, and in some embodiments, even when two wristbands 100 are provided, the radian of the band body 110 of each wristband 100 may be greater than or equal to pi, that is, the band body 110 of each wristband 100 may be provided with a major arc.

In another embodiment, referring to fig. 4, only one of the wristbands 100 may be provided, that is, one device body 200 is provided with one wristband 100, the free end of the band body 110 of the wristband is disposed near the other end of the device body 200, and the radian of the band body 110 of the wristband 100 is greater than or equal to pi, that is, the band body 110 of the wristband 100 is disposed in a major arc. In this case, the user opens or breaks the free end of the wrist band 100 to form an opening between the free end and the device body 200, which is sufficient for the wrist to enter and exit, so that the wrist can freely enter and exit the wearing ring, and the wrist-wearing device can be conveniently and quickly worn on or taken off from the wrist. It can be understood that if the radian of the band body 110 is too small, it is difficult to achieve stable wearing of the single-wrist band wrist-worn device, and if the radian of the band body 110 is too large, a part of the free end of the band body 100 is stacked inside the device main body 200, which may cause discomfort to a user during wearing and affect user experience; in this embodiment, optionally, the radian range of the band body portion 110 is 1.3 pi to 1.8 pi, and the radian range is moderate, so that both the wearing stability and the wearing comfort can be achieved.

Alternatively, referring to fig. 8, when the free ends of the two belt body portions 110 are stacked, at least one of the two opposite surfaces of the two free ends of the two stacked belt body portions is provided with protrusions 111, and the protrusions 111 may be in a flat point shape, a thorn shape or a barb shape; generally, the protrusions 111 are provided in plurality to form a protrusion group; it can be understood that the addition of the protrusions 111 increases the friction between the opposite surfaces of the two free ends of the stacked body, and reduces the probability of displacement between the two free ends of the stacked body in the length direction of the band body 110, thereby improving the wearing stability of the wristband 100, and particularly, since the increased friction is generated when the two opposite surfaces are displaced in a sliding manner, the connection force between the two free ends of the stacked body in the direction perpendicular to the outer surface of the band body 110 is not increased (the conventional magic tape mainly increases the connection force), that is, when the two free ends of the band body 110 are pulled outward (the force is applied nearly perpendicular to the outer surface of the band body 110) to wear or remove the wristband 100, the protrusions 111 do not cause any obstruction, thereby causing no additional labor to wear or remove the wristband 100. However, the design is not limited thereto, and in other embodiments, the two opposite surfaces of the two free ends of the stacked layers may be further adhered by a hook and loop fastener.

Particularly, for the thorn-shaped or barb-shaped bulge, the bulge is preferably a soft rubber bulge. Because the user acutely throws the wrist at the in-process of wearing, can cause the extrusion force that produces the vertical direction between wrist strap 100 looks lamination both ends and the relative displacement inertia of horizontal direction, the extrusion force of vertical direction can make the protruding vertical direction of flexible glue extruded, and horizontal direction relative displacement inertia can make the protruding horizontal direction of flexible glue stretched, thereby increase the protruding area of contact between another group flexible glue arch that sets up on wrist strap 100 and/or the opposite side wrist strap 100 of flexible glue, and then increase frictional force between the wrist strap 100 looks lamination both ends, thereby prevent wrist strap 100 looks lamination both ends to stagger and avoid wrist strap 100 from the wrist slippage. Optionally, especially all be equipped with the flexible glue arch in two relative surfaces at the both ends of overlapping mutually, wrist strap 100 is worn at the wrist and is rocked the in-process, and the extrusion force of vertical direction and the relative displacement inertia of horizontal direction cause two sets of flexible glue archs all to extrude deformation to glue together the winding, make wearing of wrist strap 100 more stable firm. Therefore, the wristband 100 of the present invention does not need a buckle aid and does not worry about slipping.

In other embodiments of the present invention, a soft or hard glue material may be used for the flat protrusions.

Therefore, the memory metal part 120 of the present invention can realize that the wrist-worn device can be stably supported and worn on the wrist of the user without buckling the wrist strap; the protrusions 111 at the end portions of the band body 110 can prevent the both end portions of the band body 110 from being dislocated, thereby preventing the wrist band from slipping off from the wrist due to the increased size of the wrist band, further increasing the wearing stability; in addition, the arrangement of the memory metal part 120 and the protrusion 111 also avoids the wrist strap buckling operation in the wearing process and the unbuckling operation in the removing process of the traditional wrist wearing equipment, so that the wearing and removing process becomes easier.

In an embodiment, a mounting cavity is formed in the band body 110, and the memory metal part 120 is received and mounted in the mounting cavity, that is, the memory metal part 120 is disposed in the band body 110, so as to provide physical protection for the memory metal part 120 through the band body 110.

Optionally, the recess 113 is provided as a blind hole; however, the design is not limited thereto, and in other embodiments, the recess 113 may be a through hole. Further optionally, the concave hole 113 is provided on the tape body 110 at intervals along the extending direction of the tape body 110, so that when the two free ends are different in stacking length, the protrusion 112 and the concave hole 113 can still be engaged with each other, and therefore users with different wrist sizes can enjoy wearing stability due to the engagement between the protrusion 112 and the concave hole 113.

However, in other embodiments, when the wrist band 100 has a decoration nail, the decoration nail can be inserted into the mounting hole 114, and the two opposite ends of the decoration nail are generally flush with the two opposite surfaces of the band body 110. In particular, when the decoration nail is installed in the installation hole 114, in order to limit the relative displacement between the two band body portions 110, the above-mentioned technical solution of providing the protrusion 111 may be adopted, that is, at least one of the two opposite surfaces of the two free ends of the mutually stacked band bodies is provided with the protrusion 111 (especially, a soft rubber protrusion).

It should be noted that, in general, the two technical solutions for limiting the relative displacement between the two tape body portions 110 (the technical solution for matching the protrusion 112 with the concave hole 113 and the technical solution for providing the protrusion 111) are alternatively provided, that is, only the protrusion 112 may be matched with the concave hole 113, or only the protrusion 111 (especially, a soft rubber protrusion) may be provided.

Alternatively, referring to fig. 12, the band body portion 110 includes a body section 110c and a free section 110d connected, the free section 110d constitutes a free end of the band body portion 110, that is, the mounting hole 114 is provided in the free section 110d, and at least the second metal section 122 protrudes from the body section 110c and is connected to the free section 110d for the memory metal portion 120. The free section 110d is made of hard plastic materials or other hard materials, and it can be understood that the hard materials are not easy to deform, which is beneficial to the stable combination between the protruding member 112 and the mounting hole 114 and reduces the probability that the protruding member 112 is separated from the belt body 110; in addition, in some other embodiments, the protrusion 112 may be made of a hard plastic material or other hard materials and integrally formed with the free end. Optionally, the free section 110d and the body section 110c are integrally formed by injection molding, and the injection molding mode is favorable for batch manufacturing, so that the production efficiency of products can be improved; however, the design is not limited thereto, in other embodiments, the free section 110d may be connected to the second metal section 122 in a manner of being engaged with the second metal section, and it should be noted that, at this time, the bending portion 122a of the second metal section 122 corresponding to the mounting hole 114 is bent toward the direction close to the body section 110c, so that the protrusion 112 at the mounting hole 114 can be engaged into the bending portion 122 a.
