Description

Connection structure for wearable device and wearable device

Technical field

The present invention relates to the field of wearable devices. The wearable devices may be, for example, watches, various kinds of jewelry or similar decorations, various electronic devices with or without communication functions, and the like. Therefore, the present invention relates to a connection structure for a wearable device and a wearable device including such a connection structure.

Background technique

At the moment when the sales of various watches are increasing, the appearance of watches is increasingly diversified. The beautiful appearance of the watch body and the interchangeable multi-style strap attract consumers to buy watches. Comply with consumers' expectations of pursuing product personalization.

On the one hand, the traditional watch strap part includes two parts: the exterior surface (that is, the outer side when worn) and the inner lining (that is, the inner side when worn). The inner lining part contacts the wrist. Whether the wearing experience is comfortable, little attention is paid to the appearance of the lining. In addition, the current conventional strap is limited by the buckle method, which is only applicable to one wearing method. The inner lining of the strap cannot be fastened after being reversed, and the wearing method is single.

On the other hand, with the continuous development of wearable devices such as smart bracelets, many internal sensors are equipped with a variety of sensors. When worn on the wrist, they can easily identify and record sports and sleep data. Widely welcome. Wearable devices, including smart bracelets, can also change the way they are worn by changing the watch strap, thereby playing a decorative role. Therefore, users in different seasons, or on different occasions, prefer to replace them with different ones. Strap to improve the comfort and convenience of wearing, or enhance the personal taste of the user.

Moreover, with the full integration of the wearable device and the fashion industry, consumers have also tried to provide at least one of the front and back sides of the wearable device (that is, the outer side and the inner side) with purely decorative items or accessories. Consumers can use the front-facing wearables to check information such as time when they are at work during the day, and use the accessories located on the inside during evening entertainment. Alternatively, consumers use jewelry to decorate the front of their wearable devices, and only observe the device body on the inside when they need to query information.

In the present invention, the components of the aforementioned various types of wearable devices that are used to extract information or play a decorative role are referred to as the "device main body" of the wearable device, such as, but not limited to, the dial of a watch and the display screen of a smart bracelet , Jewelry, etc.

In this case, how to provide consumers with more personalized options without increasing the purchase of a pair of straps, for example, the device main body that provides two different wearable devices has become a point of design.

In the prior art, the main body of the device is usually connected to the strap through the raw ear. When replacing the strap, a special removal tool such as a raw ear fork or a lug fork is required. For example, when removing the strap, Fork the raw ear fork into the lug, and push the raw ear fork against the raw ear so that the raw ear is pushed out by the internal spring to complete the removal of the strap; when installing the strap, you need to snap one end of the raw ear into the lug Then, use the special tool to push the other end of the raw ear into the lug, so that the raw ear is clicked in, and the strap is completed. It can be seen that the existing connection structure between the main body of the wearable device such as a smart bracelet and the strap has tedious disassembly and installation, requires special tools, single wearing mode, poor reliability and impact, such as smart bracelets, etc. Wearable device life issues.

To solve this problem, there is also a wristwatch with a reversible case in the prior art. Each end band of the watch band includes a trunnion that is pivotably and slidably mounted on the case. Insert element. Each insert element includes at least two guide angle positions corresponding to the two use positions of the watch case, respectively, and at least one longitudinal rest position in which the pivot of the insert element is prevented by the male element fitted in the female element, and one of the elements Arranged on the watch case, another element is disposed on the insert element, and a longitudinal pivot position in which the insert element moves longitudinally outward and in which the insert element is free to pivot. Although the watch can realize the flip of the watch, the structure is quite complicated, and the failure of the pivot axis will lead to the loss of function and high cost. It is generally only used in high-end watch series.

Therefore, in the field of wearable devices, there is always a need for a device body that can realize two different wearable devices with a very simple structure.

Furthermore, the connection structure for a wearable device as described above may have a further problem. On the one hand, a large external force is required to allow the second engaging member of the second connecting member to enter the first connecting member. The shape of the first engagement member is in a matching engagement (for example, the second engagement member is snapped onto the first engagement member). On the other hand, even if the second engaging member of the second connecting element and the first engaging member of the first connecting element are barely matched with a large external force, if they are to be separated (for example, to change the orientation) Outside the main body of the device), either cannot be smoothly and conveniently detached, or the two can be separated under undesired conditions (ie, the fixed connection is unreliable).

For this reason, there may also be a need in the field of wearable devices to provide a low-cost and reliable operation method. In particular, it is desirable to provide a connection structure which is convenient and easy to join, but at the same time does not accidentally disengage, and can be easily disengaged when needed.

Summary of the Invention

To this end, the present invention provides a connection structure for a wearable device, the connection structure comprising: a first connection element configured to support different device bodies of the wearable device from inside and outside when worn; a second A connecting element, a second connecting element configured to be fixedly connected to a strap of the wearable device, wherein a first engaging element is provided on the first connecting element, and a second engaging element is provided on the second connecting element, the first engaging And the second joint can be in a shape-matched joint under the force applied to them to establish a detachable connection between the main body of the device and the band, and can also be disengaged from this joint, In order to be able to change the body of the device that is on the outside when worn.

Compared with the complicated connection structure including multiple parts in the prior art, the connection structure can be connected using only a very small number of components, that is, the joints on the first connection element and the second connection element. In particular, with this connection structure, the device body of the wearable device and its strap can be reliably connected and disconnected, and the connection structure is very simple, low cost, and the operation of connection and disconnection is convenient and reliable Quite high.

It is particularly advantageous if the first connection element and the second connection element are configured to be able to be snapped into each other by means of their own elastic deformation force. Compared with the connection with the complicated structure in the prior art, the elastic deformation of the first connection element and / or the second connection element during the joining can greatly simplify the connection structure.

More advantageously, the first connection element includes a cross member for fixing the watch band and an arm member, the arm member extending from both ends of the cross member, so that the arm member can be removed from the first connection member The outer side of the first connecting element is connected to or disengaged from it, and the first joint is disposed on the inner side of the arm member facing the first connecting element, wherein the elastic deformation force is provided by the cross member of the first connecting element.

With this connection structure, the second connection element can be lightly and conveniently joined to the first connection element and maintain a reliable connection between the two and the main body of the device and the watch band. At the same time, when it is desired to replace the main body of the device, etc. The second connection element is easily disengaged from the first connection element without the need for other auxiliary tools (for example, screwdrivers or additional buttons).

In a preferred embodiment, the cross member may include at least one narrowed cross section. Since the elastic deformation force is provided only by the narrow section of the cross section, a desired deformation joining effect can be achieved with a very simple structure.

In other embodiments, the cross member may include a rod-shaped element fixedly connected to the arm member, the rod-shaped element is configured to be twisted before being fixedly connected to the arm member to provide a reply to the second connecting element. Deformation force. By using the deformation force accumulated in the rod-shaped element, a larger deformation range can be provided to the second connection element to be joined to the first connection element of various sizes.

Preferably, the cross member may include a first section made of a flexible material, and the elastic deformation force is provided by the first section. By providing a flexible material, the cross member can easily obtain the required deformation force without modifying the structure of the cross member itself. In particular, adaptive materials can be selected for different deformation forces required, such as but not limited to plastic.

Preferably, the first connection element and the second connection element are fixed to each other only by means of a shape-matching engagement between the corresponding first engagement element and the second engagement element. The fixing between the two can be completed only by the shape-matching joint, and additional fixing members can be omitted, thereby making the structure simpler and the operation can be completed with one hand when disassembling.

In an alternative embodiment, the first connecting element includes a cross member for fixing the watch band and an arm member, the arm member extending from both ends of the cross member, so that the arm member can be from the first The outside of a connecting element is connected to or disengaged from it, and the first engaging member is disposed on the inside surface of the arm member facing the first connecting element, wherein the elastic deformation force is provided by the flat plate-like element of the first connecting element.

More preferably, one of the first engaging member and the second engaging member may include a recessed portion, and the other of the first engaging member and the second engaging member may include a protruding portion matching the shape of the recessed portion. The way of joining the protruding portion and the recessed portion is easily provided on the first and second connecting members, and the structure is simpler.

In particular, one of the recessed portion and the protruding portion may be seen facing outward, and the other of the recessed portion and the protruding portion may face inward, in which the other of the recessed portion and the protruding portion faces inwardly. The corresponding engaging element is snap-fitted from both sides of the other engaging element of the first engaging element and the second engaging element. Through the enclosing joint, the joint members of the first connection element and the second connection element are not seen from the outside, so that the entire wearable device has a beautiful appearance.

Advantageously, the recessed portion may include a guide groove extending along at least a part of the corresponding first connection element or the second connection element, and the guide groove may be in communication with the recessed portion, including the corresponding second connection element or the first of the protruding portion. The connecting element is snapped into the guide groove by using its elastic deformation force and finally snapped into the recess.

With this guide groove, the joint between the first connecting element and the second connecting element can be made smoother, thereby avoiding unnecessary loss to the wearing device on the one hand, and making the joining and disengaging more convenient on the other hand . It can be understood that one of the first connection element and the second connection element has been elastically deformed when in contact with the guide groove, and thus can be easily clicked toward the recessed portion.

In particular, the size of the guide groove may be designed to be smaller than the size of the recessed portion that receives the protrusion. That is, the protruding portion is not engaged with the shape of the guide groove, but is more smoothly caught in the recess by the guide groove. As a result, the rigidity requirements of the connection element can be reduced, thereby facilitating manufacturing and improving the stability of the joint.

Preferably, the protrusion is integrally formed with the corresponding first connection element or the second connection element, or alternatively the protrusion is formed by a separate insertion element separated from the corresponding first connection element or the second connection element. The integral molding can make the connection structure of the entire wearable device simpler, and the insertion component makes the design more flexible, providing a variety of stable joints and reliable fixing possibilities.

Particularly advantageously, the first connection element and the second connection element are configured as metal elements, and one of the first connection element and the second connection element, which are located on the outside when engaged, includes on both sides with respect to the center of the device body, respectively. Two outwardly extending arm members, and the distance between the two arm members is designed so that the connecting element containing them can be elastically deformed when engaged with the other connecting element.

With the recoverable deformation force of the metal material, the connecting element itself can be prevented from being damaged during the engagement, and the action of the externally-connected connecting element to the other connecting element can be smooth, smooth, and realized. The structure of the connection is very simple.

In some embodiments, the recessed portion can also be configured as a through hole, and the protruding portion can also be configured to extend beyond or be flush with the recessed portion. This provides the possibility of connecting and fixing between the first connection element and the second connection element by means of an additional cap. In the case of flush, the appearance lines of the entire wearable device can be made more concise.

In addition, the present invention also relates to a wearable device, the wearable device comprising: a device main body; a strap; a connection structure, the connection structure includes: a first connection element, the first connection element is configured to support the wearable device from inside and outside when worn Different device main bodies; a second connection element configured to be fixedly connected to the strap of the wearable device, wherein a first joint is provided on the first connection element and a second connection element is provided on the second connection element The engaging member, the first engaging member, and the second engaging member can be in a shape-matched joint under the force applied thereto to establish a detachable connection between the device main body and the watch band, and also from this This engagement is disengaged to be able to change the body of the device that is on the outside when worn.

As a result, the wearable device that can be flipped on both sides can easily meet the needs of consumers in using and observing two different device main bodies, while making this operation very convenient, and the connection between the connection structures is also very reliable and stable.

detailed description

It should be noted that the drawings referred to are not all drawn to scale, but may be enlarged to illustrate aspects of the present invention, and in this regard, the drawings should not be construed as limiting.

As mentioned earlier, the term "device body of a wearable device" refers to a component of various types of wearable devices that is used to extract information or play a decorative role, such as, but not limited to, the dial of a watch, the display of a smart bracelet, Jewelry, etc. In the present invention, the device main body may preferably include display screens of two different watches or smart watches (the display screen may also include user interaction functions), which are respectively disposed on the outer side and the inner side of the wearable device, that is, it is necessary to At least a part of the device, which is mainly used to carry the parts of the device body, is turned over to realize the use of different device bodies.

Therefore, the wearable device 100 according to the present invention may include a connection structure, which may be composed of two elements, that is, the first connection element 10 and the second connection element. Here, the terms “first” and “second” are not intended to distinguish the primary and secondary points of the connection element, but merely indicate that the first connection element 10 is a connection element different from the second connection element 20.

More specifically, for the convenience of explanation, the first connection element 10 is defined hereinafter as a connection element configured to support the device body of the wearable device 100, and particularly capable of being worn by (a person) (the wearable) Device 100) is a type of connection element that supports different device main bodies of wearable device 100 on both the inside and outside sides. For example, the first connecting element 10 may be a dial for supporting a surface in the conventional sense or a peripheral frame for supporting a display screen in the case of a smart bracelet, and the like. However, it is also understood that when there is only one device body, the first connection element 10 may also support the device body from only one of the outside and the inside.

In addition, the second connection element 20 is defined in the present invention as a connection element configured to be fixedly connected to the band of the wearable device 100. Here, although the strap seems to be a term in the case of, for example, a watch or a smart bracelet, it can be understood that the device used to host the wearable device 100 to any component on the wearer's arm / wrist (for example, any Tethering elements) can be understood as a watch band of the present invention, such as, but not limited to, a bracelet part of an accessory. In addition, the so-called "fixed connection" means that the second connecting element 20 and the strap of the wearable device 100 are fixed during use, but this does not exclude that the second connecting element 20 can be connected to the watch when not in use. The belt is disconnected and removed for cleaning or replacement.

In the present invention, the terms "outer side (face) when worn" or "front side when worn" and "inner side (face) when worn" or "back side when worn" are relative positions relative to the wearer / Directional relationship. Specifically, the inside (or reverse) side of the wearable device 100 during wearing refers to a side that is in contact with or at least faces the skin of the arm of the wearer. Generally, the main body of the device, which is currently placed inside when worn, cannot be observed by the outside world. The outer side (or front side) of the wearable device 100 when it is worn refers to the other side opposite to the inner side. When the device main body is on the outer side when worn, it can be observed by the wearer or other people and can be used.

In order to enable the device main body and the watch band 50 to be reliably connected through the first connection element 10 and the second connection element 20, a first joint 12 is provided on the first joint 10, and a second joint is provided correspondingly. twenty two.

The first and second engaging

members

12 and 22 may be integrally formed with the first and second connecting

members

10 and 20, respectively, or alternatively, at least one of the second and second engaging

members

22 and 22 may be Components that are attached to the first connection element 10 or the second connection element 20 in any known manner (eg, mechanically, adhesively, soldered, etc.). In this regard, different embodiments will be further described below.

In order to establish a detachable connection between the device body of the wearable device 100 and the watch band 50, a shape-matching joint can be generated between the first engaging member 12 and the second engaging member 22. The term “shape-matched engagement” means that the engagement is mainly achieved by the shape-matching relationship between the first engagement member 12 and the second engagement member 22, but the possibility that the engagement is achieved by a force fit is not excluded. Here, the term “shape matching” means that the shapes of the portions for engaging with each other between the first engaging piece 12 and the second engaging piece 22 completely correspond.

Of course, the first joining member 12 and the second joining member 22 may also include portions that are not used for joining, for example, portions for connecting with the first connecting element 10 and the second connecting element 20 and the like. That is, portions that are not used for joining may not need to have a matching shape (the structure of the second joining member 22 will be further explained below).

In order to change the used / observed device body, the first connection element 10 for supporting the device body needs to be turned over. When changing the main body of the device on the outside when wearing, the first joint 12 and the second joint 22 can be disengaged from the above-mentioned shape-matched joint, so that the consumer can easily flip to the desired apparatus main body. The side.

Preferably, one of the first engaging member 12 and the second engaging member 22 includes a recessed portion, and the other of the first engaging member 12 and the second engaging member 22 includes a protruding portion that matches the shape of the recessed portion. . Although in the ninth embodiment to the sixteenth embodiment, the first engaging piece 12 and the second engaging piece 22 are respectively shown as a recessed portion and a protruding portion, this is obviously interchangeable (for example, see the second example).

For example, in the first embodiment shown in FIGS. 1A-1E, the first connection element 10 is shown as a generally oval frame for supporting the main body of the device, and the second connection element 20 is stably connected to the watch band 50 . The shape of the first connecting element 10 may also be, for example, rectangular, square, circular, polygonal, or other irregular shapes. The second connecting element 20 may be constituted by, for example, a cross member 26 that passes through the entire width of the band 50, particularly the band 50, and two arm members 24 that protrude outward from both sides of the cross member 26.

Since the width of the band 50 is generally smaller than the width of the first connecting element 10 (for example, a frame that functions as a dial), the two arm members 24 extend from the left and right ends of the cross member 26 to extend substantially obliquely outward. . However, it can also be understood that it is particularly advantageous that the distance between the free ends of the two arm members 24 may be less than or at most equal to the lateral width of the first connection element 10 or its maximum lateral width (when the first connection element 10 is non-square). Here, the term “longitudinal” refers to an extending direction along the circumference of the wearable device 100, and “lateral” refers to a direction orthogonal to the longitudinal direction.

Since the distance between the two arm members can be designed to be smaller than the size on the other connecting element to be joined, the elastic deformation force of the connecting element itself (for example, a metal material) containing the arm member can be utilized, Easily snaps onto another connection element. This engagement is not necessarily only at the engaged position, but may occur at any contact position along the direction toward the engaged position.

In addition, it can be understood that this elastic deformation can change its size during the continuous movement towards the joint position, for example, the elastic deformation force increases (this is, for example, due to the small dimensional difference when the two connecting elements have just contacted, and then The difference in size between the two towards the final engagement position is increasing, but it can also be reversed).

On the inner side of the two arm members 24, in particular at positions close to their free ends (but also other advantageous positions), projections which face inwardly, ie face each other, may be provided. The second engaging piece 22 of the protruding portion as the second connecting element 20 may have any suitable shape and may have any suitable protruding height, as long as the protruding portion is in the shape of the corresponding first engaging piece 12 on the first connecting element 10 Just match.

To this end, corresponding first engaging members 12 may be provided at appropriate positions of the first connecting element 10, as shown in FIG. 1B, near the lateral ends of the first connecting element 10 in the vicinity. The first joint member 12 can be configured, for example, as a recessed portion matching the shape of the above-mentioned protruding portion, so as to achieve a shape-matched joint between the two.

When the force (usually a small force, which can come from the outside, or the elastic deformation force generated by the connecting element itself, etc.), the consumer can fixedly connect the second connecting element 20 with the watch band 50 The second engaging member 22 of the first engaging member 12 is engaged with the first engaging member 12 provided on the first connecting member 10. That is, in this embodiment, the protrusions on the two arm members 24 are snapped onto the first connecting member 10. Inside the depression.

In order to achieve convenient joining, the rigidity of the second connecting element 20 including the second joining member 22 may be set to a stiffness value that facilitates joining into the recessed portion, for example, having a certain degree of deformability.

Compared with the connection with complicated structure in the prior art, the elastic deformation of the first connection element and / or the second connection element when they are joined can greatly simplify the connection structure, that is, to a certain extent by the material of the connection element itself. The elastic deformation can be easily engaged, especially snapped into another connecting element.

In addition, this elastic deformation is also preferably substantially recoverable to minimize damage to itself due to the engagement between the engagement members of the two connecting elements, especially the snap fit. For example, the material of at least a part of the first connection element and / or the second connection element, mainly at least a part for bonding, is an elastically deformable metal.

Furthermore, in order to enhance the convenience and reliability of such joining, a guide groove 16 is advantageously provided on the first connecting element 10. The guide groove 16 can only extend over a part of the first connection element 10, for example, in particular along the periphery of the first connection element 10.

Preferably, the guide groove 16 communicates with a recessed portion provided on the first connection element 10. Therefore, before engaging the second engaging member 22 into the first engaging member 12, the second engaging member 22 can be brought into contact with the guide groove 16 and can be slid forward by the guide groove 16 so as to be engaged from the guide groove 16. Into the first engaging member 12, that is, the recessed portion.

In particular, the size of the guide groove 16 is smaller than the size of the recessed portion, that is, the groove width of the guide groove 16 is smaller than the width of the recessed portion. Therefore, the second engaging member 22 (a protruding portion in this embodiment) is not an engagement matching the shape of the guide groove 16, but is directed toward the first engaging member 12 (a recessed portion in this embodiment) by only the guiding groove 16. ) Orientation. In this way, the entire joining process will become very smooth.

Although the guide grooves 16 shown in FIGS. 1A-1E extend along approximately half of the periphery of the first connection element 10 (the main body of the device is not shown), it can be understood that the guide grooves 16 may extend from the second connection element 20, that is, the arm portion. The position where the member 24 just contacts the first connection element 10 starts to extend toward the recessed portion. The first contact position between the arm member 24 and the first connection element 10 may depend on the relationship between the lateral width of the first connection element 10 and the distance between the free ends of the arm member 24.

In this first embodiment, the first connection element 10 and the second connection element 20 may be fixed to each other only by means of a shape-matching engagement between the corresponding first engagement piece 12 and the second engagement piece 22. In other words, there are other embodiments in which the engagement by means of a shape match between the corresponding first engaging member 12 and the second engaging member 22 is not sufficient to stably fix the first connection element 10 and the second connection element 20.

In addition, it can be understood that one of the recessed portion and the protruding portion may face outward and be visible to a consumer, and the other of the recessed portion and the protruding portion may face inward. For example, in the first embodiment shown in FIGS. 1A-1E, the recessed portion on the first connection element 10 is facing outward, and the protruding portion on the second connection element 20 is facing inward.

However, it can also be understood that, in other embodiments as shown in FIGS. 7 and 8, the recessed portion on the first connection element 10 may also be facing inward, that is, not visible from the outside, and the second connection element The protrusions on 20 are outward facing.

In any case, it is preferable that the engaging member (for example, the second engaging member 22 in the first embodiment) corresponding to the inwardly facing one of the recessed portion and the protruding portion be removed from the first engaging member 12 and Two sides of another engaging element (for example, the first engaging element 12 in the first embodiment) in the second engaging element 22 are snap-fitted to it. That is, the engaging member including the inwardly facing depression or protrusion generally has a larger pitch size, so that it can surround another engaging member including the outwardly facing depression or protrusion to achieve the shape from the outside to the inside. Matching joints.

In the second embodiment shown in FIGS. 2A-2E, the first connection element 10 includes an outwardly facing protrusion, and the second connection element 20 correspondingly includes an inwardly facing depression. The second embodiment does not include the guide groove 16. The recessed portions on the two arm members 24 surround the first connecting element 10 and its first engaging piece 12 (ie, the protruding portions) from both sides, thereby producing an engaging effect. During this joining process, the arm member 24 can be deformed by elasticity to more reliably join the first connecting element 10.

In the third embodiment shown in FIGS. 3A to 3E, the protruding portion is also provided on the first connecting element 10, but in this embodiment, the second engaging member 22, that is, the protruding portion is not connected to the first connecting element. 10 is formed integrally, but is provided as an insertion element 18 on the first connection element 10.

More specifically, as clearly shown in FIG. 3B, first four through holes are provided on the first connection element 10, and the positions of the four through holes correspond to the positions of the protrusions on the second connection element 20. . Each of the insertion elements 18 includes two through portions that can extend through such a through hole and a connecting portion that connects the two through portions to each other.

In this embodiment, the penetration portions of the insertion element 18 pass through the through holes from the inside of the first connection element 10 respectively, so the connection portions are located inside the first connection element 10. It can be understood that, preferably, the position of the connecting portion in the first connecting element 10 should not interfere with the setting of the device body.

In this embodiment, the second joint 22 on the second connection element 20 is also configured as a through-hole. Therefore, after passing through the through hole, the insertion portion of each insertion element 18 may continue to pass through the second engaging member 22 on the second connection element 20 surrounding the first connection element 10 from both sides, that is, the through hole. In other words, the extended length of the penetration portion of the insertion element 18 is preferably larger than the sum of the depths of the through holes on the first connection element 10 and the second connection element 20.

In particular, the wearable device 100 further includes a cap for fixing the first connection element 10 and the second connection element 20 to each other, and the cap is respectively matched with the penetration part of each insertion element 18, and can be screwed to the insertion, for example. The passing portion of the element 18 that has passed through the two through holes in succession (which may include necessary threads or related snap-fit structures, which will not be repeated here).

In the fourth embodiment shown in Figs. 4A-4E, such an insertion element 18 formed separately from the first connection element 10 is from the outside of the first connection element 10, especially also from the outer connection of the second connection element 20 The through-holes formed in the first connection element 10 and the second connection element 20 are inserted, respectively, and the first connection element 10 and the second connection element 20 are fixed inside the first connection element 10 by means such as a cap. For example, the insertion element 18 may be configured as a screw, and the cap may be a corresponding nut.

However, it is also conceivable that the hole on the first connection element 10 is a blind hole, that is, the insertion element 18 is caught in the blind hole of the first connection element 10 after passing through the through hole on the second connection element 20, and It does not pass through the first connection element 10. In this case, the insertion element 18 can function similar to a conventional expansion screw.

In addition, in the fifth embodiment shown in FIGS. 5A-5E, it is also conceivable that a deformable member is provided on the first connection element 10. As clearly shown in FIG. 5B, the deformable member may be configured to extend around a substantially half of the peripheral edge of the first connection member 10, and the deformable members each have a convex portion protruding beyond the first connection member 10.

As shown in FIG. 5A, the consumer can plug the deformable member into the inside of the first connection element 10 having a size slightly smaller than that of the first connection element 10, and the convex portion of the deformable member is located in the corresponding through hole on the first connection element 10. The threaded position thus provides a first engaging element 12 of the first connection element 10.

Then, similar to the foregoing embodiment, the consumer can sleeve the second engaging member 22 on the second connecting element 20, here a through hole, on the convex portion of the deformable member, with or without the aid of an additional cap Fix the two together.

In the sixth embodiment shown in FIGS. 6A-6E, the second engaging member 22 (ie, the recessed portion) on the second connection member 20 is not provided as a through hole, and the insertion member 18 is removed from the first connection member 10. The inside of the through hole passes through the through hole provided on the first connecting element 10 so as to be engaged with the second engaging member 22. The size of the portion of the insertion element 18 inside the first connection element 10 is larger than the size of the portion passing through the through hole and the recessed portion to ensure a fixed joint between the first connection element 10 and the second connection element 20.

Further, the engaging member configured as a protrusion according to the present invention may be flush with another engaging member configured as a recessed portion, extend beyond the recessed portion (for example, when the recessed portion is a through hole), or be located within the recessed portion (for example , When the depression is a blind hole).

In the ninth embodiment shown in FIGS. 9A to 9D, the first connection element 10 is similarly shown as a generally oval frame for supporting the main body of the device, and the second connection element 20 is stably connected to the band . The shape of the first connection element 10 may also be, for example, a track shape, a rectangle, a square, a circle, a polygon, or other irregular shapes.

The second connection element 20 may similarly also include a cross member 26 and an arm member 24. The cross member 26 is used to fix the watch band, for example, it can pass through the entire width of the watch band, especially the watch band. The arm member 24 is generally two arms (but not limited to this), and the arm member 24 projects outward from both sides of the cross member 26 (ie, left and right ends in the lateral direction). The outwardly extending direction is suitable to enable the arm member 24 to be connected to or from the outside of the first connection element 10 (in the embodiments shown in the drawings, respectively from the left and right outside of the first connection element 10). It's off.

In the present invention, the term “longitudinal” refers to an extending direction along the circumference of the wearable device 100, and “lateral” refers to a direction orthogonal to the longitudinal direction. Alternatively, the term "lateral" may also refer to a direction substantially extending along the wrist of the wearable device, or a direction substantially perpendicular to the extending direction of the main length of the band. However, it can be understood that “horizontal” does not necessarily follow the above directions exactly, but may have components in the above directions.

As exemplarily shown in FIGS. 9D, 10D, 11D, etc., the first engaging piece 12 is configured as a recessed portion, and the second engaging piece 22 includes a protruding portion that matches the shape of the recessed portion. In addition to the protruding portion, the second engaging piece 22 also includes a transition portion extending between the inner side surface of the arm member 24 and the protruding portion. Here, the “inner side surface of the arm member 24” means that when the second connection element 20 is engaged with the first connection element 10 (as shown in FIG. 9A), the arm member 24 of the second connection element 20 faces the first A side of a connecting element 10.

Preferably, the transition portion is oriented to extend perpendicular to the inner side of the arm member 24. Due to this vertical protruding structure, the structural strength between the second joint 22 and the arm member 24 during manufacture can be ensured, and further, when the second joint 22 and the first joint 12 are engaged and disengaged, the first The two joint members 22 do not break or break from the arm member 24. At the same time, with the transition portion, the protruding portion can be more fully engaged with the recessed portion to improve the reliability of the connection between the second connection element 20 and the first connection element 10.

When a user applies a force to the second connection element 20, elastic deformation (force) occurs due to the structure of the second connection element itself. Under the action of this elastic deformation force, the user can join the second engaging member 22 of the second connecting member 20 fixedly connected to the watch band into the first engaging member 12 provided on the first connecting member 10, that is, In this embodiment, the protrusions on the two arm members 24 are snap-fitted into the recesses on the first connection element 10.

Compared with the connection with complicated structure in the prior art, the elastic deformation (force) of the first connection element and / or the second connection element when they are joined can greatly simplify the connection structure, that is, it can be easily joined to, especially It snaps into another connection element. In the following embodiments, how this elastic force is provided by the second connection element 20 will be described in detail.

In any case, this elastic deformation is substantially recoverable so that the first connection element and the second connection element can be easily separated after being joined. At the same time, such recoverable elastic deformation can also minimize the damage to itself caused by the joint between the joint members of the two connecting elements, especially the snap fit. However, it can be understood that, in addition to the elastic deformation, in some specific embodiments, the second connecting element 20 also undergoes partial plastic deformation, but the degree of this plastic deformation should not affect its repeated connection with the first connecting element. Within the bounds.

In the ninth and tenth embodiments as shown in FIGS. 9A-9D and FIGS. 10A-10D, the cross member 26 of the second connection element 20 includes a first section made of a flexible material. Here, the term “flexible material” may refer to various materials that can provide elastic deformation force, which are well known in the art. For example, the flexible material may be a polymer material (for example, PE, PU, PP, etc.), a carbon fiber reinforced resin, a wood-based fiber, and the like, but is not limited thereto. It can be understood that "made of a flexible material" does not exclude materials in the first paragraph that also have other components. However, in any case, at least the flexible material in the first section is suitable to provide sufficient elastic deformation force, so that the second connection element 20 can be connected to the first connection element 10, especially the second connection. The second joint 22 of the element 20 can be engaged with the first joint 12 of the first connection element 10.

In the first section of the embodiment made of a flexible material, other parts of the cross member 26 may be made of a non-flexible material, such as various metal alloys with a hardness that is much higher than (that is, the hardness is not on an order of magnitude) a flexible material. (For example, steel alloys), precious metals (platinum, silver, gold, etc.), titanium (alloys). Or, to be more precise, although some metals may also have a small hardness, they are only deformable but not restorative (for example, gold, silver, etc.), so the second connection element composed of only these materials cannot be achieved The elastic restoring force in the present invention should use the flexible material as described above or other well-known shape memory materials.

However, it is worth noting that in other embodiments of the present invention that provide elastic deformation force in other ways, the connection structure, especially the cross member 26 and / or the arm member 24 of the second connection element 20 may be entirely made of the aforementioned non-flexible Made of material.

Preferably, the cross member 26 further includes a second section and a third section which are fixedly connected to the arm member 24, respectively. The aforementioned first section made of a flexible material (for example, plastic) is disposed between the second section and the third section, that is, the first section made of a flexible material (for example, plastic) is located at a substantially middle position of the cross member 26, and Not immediately adjacent the arm member 24 extending from the cross member 26. In this case, the first section in a substantially intermediate position may advantageously provide a balanced and stable elastic deformation force to the arm members 24 extending on both sides.

In particular, the second and third sections may be made of a metallic material, or other known materials (ie, non-flexible materials) that are different from the elastic deformation force of the plastic of the first section. For example, the second and third sections may be made of the same or different materials. The use of, for example, a metal material (such as a steel alloy) is because sufficient rigidity of the cross member and thus the second connection element 20 can be ensured, thereby preventing undesired disengagement after joining with the first connection element 10 due to insufficient rigidity thereof. It can be understood that the second section and the third section can also be formed integrally with the arm member 24 when the second connecting element 20 is manufactured, but it can also be other permanent or detachable fixed connections with the arm member 24.

However, it is also understood that the cross member 26 may include more than one first section made of plastic. For example, the first section may be arranged at intervals between any two sections of metal material (but the first section is usually not directly adjacent to the arm member 24) to further adjust the required elastic deformation force.

This first segment can be connected to the second and third segments on its left and right sides in various known ways. For connection, the first section may include a connecting section extending from its left and right free ends, and the diameter of such a connecting section is usually smaller than the diameter of the first section itself. Correspondingly, the second and third sections contain holes for receiving such connecting sections, the size of the holes being adapted to the size of the connecting sections.

In the tenth embodiment of FIGS. 10A-10D, small holes may be further provided on the connecting sections on both sides of the first section. After inserting the connecting section of the first section into the receiving holes in the second section and the third section on the left and right sides, external rivets can be used to rive into the small holes provided in the connecting section of the first section, thereby strengthening Reliability of fixed connection between sections of the cross member 26. In a particular embodiment, the rivet may be only a rod-shaped element. After it is inserted into the small hole, it may be heated to cause it to melt in the small hole, thereby forming a permanent fixed connection.

Alternatively, in the tenth embodiment of FIGS. 2A-2D, after inserting the connecting section of the first section into the receiving holes in the second and third sections on the left and right sides thereof, screws or other threads may be tightened The pieces are screwed into the threaded holes provided on the connecting section of the first section to achieve a detachable fastening connection.

Here, the cross section of the cross member 26, or the cross sections of the first section, the second section, and the third section may be circular, but is not limited thereto, but may be in any desired shape. For example, the cross-section of the connecting section of the first section and the receiving hole in the second and third sections may be non-circular, for example, square, thereby automatically preventing the connecting section from Unwanted rotation in the receiving hole.

In the embodiment shown in Figs. 16A-16D, although similar to the embodiment shown in Figs. 9A-10D described above, there is also a first segment made of a flexible material, but this first segment is from the second connection element The outside of 20 may be invisible (as shown most clearly in FIGS. 16C-16D) or at least a portion may be invisible (not shown).

To this end, a hollow groove (also referred to as a “rail”) extending at least along a portion of the length of the cross member 26 is formed inside the cross member 26. In the embodiment shown in FIGS. 16A-16D, the hollow grooves are respectively provided near both ends of the cross member 26 near the arm member 24, and are preferably at the axial center position of the cross member 26. However, this is obviously not necessary, because the hollow grooves may also have only one or more than two (distributed over the entire length of the cross member 26 and spaced from each other).

A first section made of a flexible material can be inserted into this hollow groove along such a "rail", for example from both free ends of the cross member 26. In a particularly preferred embodiment, the end of the first section remote from the arm member 24 is stopped by the interior of the cross member 26, and the opposite end of the first section near the arm member 24 may be performed by an additional fixing device fixed. As exemplarily shown in FIG. 16C, the fixing device may be a threaded fastener, and the end of the arm member 24 corresponding to the end of the cross member 26 includes a threaded hole to receive the threaded fastener. In other words, the fixing device is inserted inwardly from both lateral ends of the cross member 26 (if correspondingly provided with two hollow grooves) for fixing. Such a fixing device is visible from the outside of the second connection structure, so that it can flexibly provide aesthetics and fashion as required.

In other embodiments, the hollow groove may also be exposed at least partially outwardly, rather than being completely invisible from the outside of the cross member 26. For example, a part of the hollow groove of the cross member 26 may be exposed to the outside, so that the first section can be directly inserted from the outside (for example, it can be inserted by virtue of its own elastic deformation). The length should be less than the length of the first segment so that the first segment does not undesirably fall out of the hollow groove.

In addition, in the embodiment shown in Figs. 16A-16D, the cross-section of the cross member 26 is preferably non-circular (such as oval, track-shaped, etc.), thereby facilitating the subsequent attachment of such as a belt or the like. Strap.

In other embodiments, the cross member 26 may include at least one narrowed cross-section. Here, the term “narrowed cross section” means that the cross-sectional area of the section is reduced compared to other sections of the cross member 26, but the manner and proportion of reduction are not limited. In other words, various forms of the narrowed cross section are within the protection scope of the present invention, as long as the narrowed cross section allows the cross member 26 and thus the second connecting element 20 to generate sufficient elastic deformation force to engage the first One connection element 10 is detached from the first connection element 10.

In a preferred embodiment, such a cross-sectional narrowing may be located at the center of the cross member 26. However, the cross-sectional narrowed portion may be located in the vicinity of at least one, preferably both, of the left and right ends of the cross member 26 for fixed connection with the arm member 24.

Here, the term “near” refers to a portion in the cross member 26 that has not reached the arm member 24 (ie, a portion that does not directly abut the arm member 24). Advantageously, when a cross-sectional narrowed portion located near the left and right ends is included, the cross-sectional narrowed portion is spaced apart from the arm member 24 by a distance. Since the narrowed cross section is usually a stress weak point of the cross member 26, making the narrowed cross section not at the left and right ends can prevent the arm member 24 from joining to the first connecting element 10 (i.e., the arm member 24 The second joint member (the second joint member 22 is joined to the first joint member 12), and the vibration or other conditions caused the cross member 26 to break undesirably at the narrowed cross section.

In the embodiments shown in FIGS. 11A-11D, FIGS. 12A-12D, and FIGS. 13A-13D, the cross-sectional narrowed portion may be formed by a notch portion provided on the cross member 26. The “notch portion” mainly refers to a portion that is recessed inward from a contoured surface of the cross member 26, which can be formed when the cross member 26 is manufactured by various known means. In order to describe the positioning of the notch portion on the cross member 26, the “inside” and “outer” of the cross member 26 are defined first. Specifically, when the second connection element 20 and the first connection element 10 are connected to each other, the cross member 26 includes an inner side facing the first connection element 10 and an outer side far from the first connection element 10.

In the above-mentioned embodiment, the cross member 26 may include an inner notch portion provided on the inner side thereof and an outer notch portion provided on the outer side thereof. However, it can be understood that, in the present invention, the cross member 26 may include only the inner notch portion or the outer notch portion. In addition, the numbers of the inside notch portions and the outside notch portions need not correspond one-to-one as shown in FIG. 13D.

As shown most clearly in FIGS. 11D, 12D, and 13D, the inside notch portion and the outside notch portion of the cross member 26 may be staggered from each other along the length direction of the cross member 26. Since the cutout portions are staggered from each other, the aforementioned cross-sectional narrowed portion can be formed on the cross member 26 (that is, the cross-sectional area is reduced). In particular, it can be seen that a meandering cross-section narrowing can be formed on the cross member 26. This narrowed cross section can provide a very favorable deformation force to the second connection element 20.

As shown in FIGS. 11D and 12D, the cross member 26 may include at least one inside notch portion and a plurality of outside notch portions. In both embodiments, at least one of the inside notches is arranged between any two adjacent notches of the plurality of outside notches.

Specifically, in the eleventh embodiment, the cross member 26 includes two outer notch portions and one inner notch portion, and the two outer notch portions are respectively located on the left and right sides of one inner notch portion (that is, one inner notch portion). Laterally adjacent but spaced a distance apart to form a narrowed cross section). In the twelfth embodiment, the cross member 26 includes three outer notch portions and two inner notch portions. Any two adjacent outer notch portions of the three outer notch portions are respectively located in the two inner notch portions. Left and right sides of one inside notch. Or simply put, the outer notch and the inner notch are offset from each other on the cross member 26.

In addition, the solutions of the eleventh, twelfth and thirteenth embodiments can also be combined, for example, including both the outer notch and the inner notch near the left and right ends, and at the approximate middle position of the cross member 26 Includes an outside notch and an inside notch to flexibly provide any desired deformation force.

In the embodiment shown in FIGS. 15A-15D, the cross member 26 may include a plurality of rod-shaped elements fixedly connected to the arm member 24 (two rod-shaped elements are exemplarily shown in the figure, but the present invention is not limited to this. This number). Here, a “rod-shaped element” refers to an element whose length is the direction of its largest dimension, and its cross-sectional size is significantly smaller than the length, especially an order of magnitude smaller.

It can be seen that these multiple rod-shaped elements are configured to be able to be twisted around each other. When fixed to the arm member 24 after being twisted and twisted with each other, the internal "storage" of these rod-shaped elements has a tendency to return so that the two are no longer twisted and twisted with each other, and this tendency can be provided to the second connection element 20 ( Elastic) deformation force.

As shown more clearly in FIG. 15C, each of the plurality of rod-shaped elements can be inserted into a corresponding receiving hole in the arm member 24 so as to be fixedly connected thereto. However, the present invention does not exclude other fixing methods other than the insertion. Since this is not the focus of the present invention, it will not be repeated here.

In addition, it is also conceivable that the transverse member 26 includes only a single rod-shaped element, which should be twisted in advance to generate a restoring force returning to its initial non-torsional state after it is fixedly connected to the arm member 24 . This can likewise provide (elastic) deformation force to the second connection element 20.

In addition to the deformation force scheme of the second connection element 20 provided by the cross member 26 explained above with reference to the drawings, in other embodiments (such as the fourteenth embodiment shown in FIGS. 14A-14D), the second connection is facilitated. The deforming force of the element 20 joined to the first connection element 10, securely fixed, and disengaged therefrom may also be provided by the arm member 24. It can be understood that the deformation force may be provided by the arm member 24 and / or the cross member 26 (ie, the possibility of being provided by the arm member 24 and the cross member 26 together is not excluded).

As best shown in Figure 14D, the arm member 24 may be designed as a flat plate-like element. Here, the term “flat plate-like” means that the thickness of the element is significantly smaller than the dimensions in other directions, or is generally thinner. With such a flat plate-like element, the rigidity of the arm member 24 can be reduced (especially when the arm member 24 is made of metal), thereby providing a certain deformation force.

Therefore, in a preferred embodiment of the present invention, due to the elastic deformation force provided by the second connecting element, the joining between the first connecting element 10 and the second connecting element 20 by means of their respective engaging members is without any additional Can be easily engaged and disengaged without using other fasteners (such as the aforementioned caps) or without using other tools (for example, screwdrivers), and the first connection element 10 and the second connection element 20 are not damaged Degree of deformation.

In the present invention, different device bodies, such as two watches, may be provided on the same first connection element 10. For example, two watches are supported from the front and back sides of the first connection element 10, respectively.

In particular, the first connection element 10 of the wearable device 100 according to the present invention is further provided with a device for supplying power to the device body, and such power supply may be independent or together, so that the two The independent role of each device body.

Although various embodiments of the present invention have been described with reference to a wearable device 100 that does not show a device main body, it should be understood that embodiments within the scope of the present invention can also be applied to other needs having similar structures and / or functions Flip on both sides of the device.

The foregoing description has given many features and advantages, including various alternative embodiments, and details of the structure and function of the apparatus and method. The intentions herein are exemplary and not exhaustive or limiting.

It will be apparent to those skilled in the art that various modifications can be made to the full range indicated by the broad upper meaning of the terms expressed in the appended claims, particularly in terms of structure, materials, elements, parts, shapes, The dimensions and arrangement of components, including combinations of these aspects within the scope of the principles described herein.
