For more clearly illustrating embodiments of the present disclosure or the technical solutions in the conventional technology, drawings referred to for describing the embodiments or the conventional technology will be briefly described hereinafter. Apparently, drawings in the following description are only examples of the present application, and for the person skilled in the art, other drawings may be obtained based on the provided drawings without any creative efforts.
The realization of the objects, functional characteristics and advantages of the present disclosure will be further described in conjunction with the embodiments and with reference to the drawings.
The technical solutions according to the embodiments of the present disclosure will be described clearly and completely as follows in conjunction with the drawings in the embodiments of the present application. It is apparent that the described embodiments are only a part of the embodiments according to the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained without creative efforts by those of ordinary skill in the art shall fall within the protection scope of the present application.
In the present application, a relation term such as “first” and “second” herein is only used to distinguish one entity or operation from another entity or operation, and does not necessarily require or imply that there is an actual relation or sequence between these entities or operations. Moreover, the terms “comprise”, “include”, or any other variants thereof are intended to encompass a non-exclusive inclusion, such that the process, method, article, or device including a series of elements includes not only those elements but also those elements that are not explicitly listed, or the elements that are inherent to such process, method, article, or device. Unless explicitly limited, the statement “including a . . . ” does not exclude the case that other similar elements may exist in the process, the method, the article or the device other than enumerated elements.
A wrist wearable device is provided according to the present application. Referring to
It should be noted that the arc-shaped wearing state of the wristband 100 in the present disclosure refers to that the wristband 100 has only one form in a natural state, that is, the wristband 100 is only naturally maintained in an arc-shaped state, which is different from a clap ring. In the natural state, the clap ring may have two forms, one is a straight form, and the other is an arc (circular) form. The clap ring in straight form can be transformed into the arc form to be wearable after clapping the wrist. Of course, it should be noted that in the present application, the wristband 100 “only being maintained in an arc-shaped state” is not intended to limit the deformability of the wristband 100. At least, under the action of external force, the free end of the wristband 100 can be deformed and splayed outwards, so that the user can wear or put off the wrist wearable device from the wrist, and when the external force disappears, the deformation of the wristband 100 can self-recover and return to the arc-shaped wear state.
Referring to
It can be understood that memory metal is super-flexibility, which means that under the action of external force, the memory metal has much larger deformation recovery ability than ordinary metals, that is, a large strain generated in the loading process (e.g. the wearing process/putting off process) will be eliminated as unloading, so as to return to a memory shape (arc shape).
In an embodiment, each device body 200 is provided with two wristbands 100, an end of a wristband body portion 110 of one wristband 100 is connected to an end of the device body 200, and an end of a wristband body portion 110 of the other wristband 100 is connected to the other end of the device body 200, and these two wristbands 100 jointly enclose a wearing space of the wrist wearable device. In an embodiment, referring to
In a further embodiment, in a case that there are two wristbands 100, the radian of the wristband body portion 110 of each wristband 100 is less than π, that is, the wristband body portion 110 of each wristband 100 is arranged in a minor arc shape. It can be understood that, due to of the presence of the device body 200, the two wristbands 100 can be enclosed to form a shape that stably surrounds the user's wrist without the radian equaling to λ, so as to ensure the wearing stability while saving the material of the wristband 100, thereby reducing material cost. However, the present disclosure is not limited hereto, in some embodiments, even in a case that there are two wristbands 100, the radian of the wristband body portion 110 of each wristband 100 can be greater than or equal to π, that is, the wristband body portion 110 of each wristband 100 can also be arranged in a major arc shape.
It should be noted that, in another embodiment, referring to
In an embodiment, referring to
Especially for thorn-shaped or barb-shaped embossments, preferably, the embossments are soft rubber-embossments. During wearing, as the user vigorously shakes the wrist, it will cause vertical squeezing force and horizontal relative displacement inertia between the two overlapped ends of the wristbands 100, where the vertical squeezing force will squeeze the soft rubber embossments vertically, and the horizontal relative displacement inertia will stretch the soft rubber embossments in the horizontal direction, so that the contact area between the soft rubber embossments and the opposite wristband 100 and/or another set of soft rubber embossments on the opposite wristband 100 is increased, which further increases the frictional force between the overlapped ends of the wristbands 100, and prevents the overlapped ends of the wristbands 100 from being staggered, thereby preventing the wristbands 100 from slipping off the wrist. In an embodiment, especially in a case that soft rubber embossments are arranged on the two opposite surfaces of the two overlapped ends, when the wristbands 100 are worn on the wrist and shaken, the vertical squeezing force and the horizontal relative displacement inertia will squeeze and deform the two sets of soft rubber embossments, which thereby adhere and wind together, so that the wearing of the wristband 100 is more stable and reliable. Therefore, the wristband 100 of the present disclosure does not need the assistance of a wristband buckle and the concern of slippage is not necessary.
In other embodiments of the present application, soft rubber or hard rubber materials may also be adopted for flat embossments.
Therefore, the memory metal portion 120 of the present disclosure can realize that the wrist wearable device is stably supported and worn on the user's wrist without buckling the wristband buckle; the embossments 111 at an end of the wristband body portion 110 is configured to prevent the two ends of the wristband body portion 110 from being staggered, so as to prevent the size of the wristband ring from expanding and thus slipping off the wrist, which further increases the wearing stability. In addition, the arrangement of the memory metal portion 120 and the embossments 111 also avoids the buckling operation and unbuckling operation to the wristband buckle of the traditional wrist wearable device during the wearing process and putting-off process, which makes the wearing and putting-off process easier.
In an embodiment, a mounting cavity is arranged in the wristband body portion 110, and the memory metal portion 120 is accommodated and mounted in the mounting cavity, that is, the memory metal portion 120 is arranged in the wristband body portion 110, so that the memory metal portion 120 is physical protected by the wristband body portion 110.

In an embodiment, the cap 140 may be made of soft rubber, hard rubber, metal, etc. In a further embodiment, the cap 140 may be connected to the wristband body portion 110 by but not limited to, thermal-press connection, adhesive connection, etc.
In an embodiment, in a case that the memory metal portion 120 is embodied as a memory metal wire, an end of the memory metal wire is arranged in a spherical shape or a spherical-like shape, so as to reduce the sharpness of the end of the memory metal wire and reduce the probability of the end of the memory metal wire penetrating through the wristband body portion 110. It should be understood that the spherical or spherical-like structure at the end of the memory metal wire is thickened, that is, the diameter of the spherical or spherical-like structure is larger than the diameter of the memory metal wire.
In an embodiment, a positioning groove 140a for accommodating the spherical or spherical-like shaped end of the memory metal wire is formed in the cap 140, so as to prevent the end of the memory metal wire from detaching from the cap 140 and reduce the slippage of the memory metal wire relative to the mounting cavity. In a further embodiment, referring to
Further, the wristband body portion 110 is made of fabric and/or soft rubber and/or hard rubber. It should be noted that, in addition that the wristband body portion 110 is made of single fabric or single soft rubber or single hard rubber (Particularly, in a case that the wristband body portion 110 is made of single hard rubber, the whole wristband body portion 110 is embodied as a long strip shape and has sufficient bendable flexibility), the wristband body portion 110 may also be made of two or more of the above materials. For example, referring to

In an embodiment, referring to
In an embodiment, at least one of the connecting portion 130 and the buckling block 300 is a magnet, at most one of the connecting portion 130 and the buckling block 300 is made of magnetic metal material. That is, in this embodiment, it may be the case that the buckling block 300 is a magnet and the connecting portion 130 is made of magnetic metal material, and it may also be the case that the connecting portion 130 is a magnet, and the buckling block 300 is made of magnetic metal material, and it may also be the case that the buckling block 300 and the connecting portion 130 are both magnets. In this case, when arranging magnetic poles of the buckling hole 202 and the connecting portion 130, it should be ensured that the buckling block 300 can be buckled with the buckling groove 131 while being magnetically attracted to the connecting portion 130. That is, the magnetic pole on a part of the buckling block 300, which is configured to be in contact with the buckling groove 131, should be opposite to the magnetic pole at the buckling groove 131 of the connecting portion 130. The above three arrangements can make the buckling block 300 magnetically attracted to the connecting portion 130, so that the buckling block 300 is stably buckled in the buckling groove 131 to ensure the wristband 100 of being locked.
Further, in this embodiment, the buckling block 300 is a magnet, and the connecting portion 130 includes a magnetic metal sheet or a magnetic sheet arranged in the buckling groove 131.
