Description

Technical Field

[0001] This disclosure relates to the field of wearable device technology, and more specifically, to a head structure and a wearable device. Background Technology

[0002] As a wearable device, watches are loved by a wide range of consumers. Watches can be divided into traditional watches and smartwatches; traditional watches are only used for telling or displaying time, while smartwatches, in addition to telling or displaying time, should also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction, making them more popular with the public.

[0003] The current way of wearing watches is relatively simple, which reduces the diversity of product wearing.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0046] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0047] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0048] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0049] This disclosure provides a wearable device that enhances the versatility of wearing wearable devices. The wearable device can be a traditional watch, a smartwatch, a smart bracelet, or similar device. Taking a smartwatch as an example, the wearable device may include a watch case, a watch face, a watch band 01, and a headband structure. The watch face is housed within the watch case and is used to display information, including but not limited to the time display, interactive displays (such as WeChat, call displays), and navigation displays. The watch case and watch band 01 are connected via the headband structure. The watch band 01 can be made of materials such as metal, genuine leather, nylon, or rubber.

[0050] See Figures 1-4 The watch head link structure may include a first head link 1, a second head link 2, and a rotating structure. The first head link 1 is used to connect to the watch case; the second head link 2 is used to connect to the watch strap 01; the rotating structure includes a connecting part 21 and a first connecting assembly 3, with the first head link 1 and the second head link 2 connected via the connecting part 21; in the released state, the first head link 1 and the second head link 2 rotate relative to each other about the connecting part 21; in the locked state, the first head link 1 and the second head link 2 are relatively fixed.

[0051] Thus, in the released state, the first lead 1 and the second lead 2 can rotate relative to each other about the connecting part 21. In the locked state, the first lead 1 and the second lead 2 can be relatively fixed. During the rotation of the second lead 2 by 180°, the watch strap 01 will rotate by 180°, thereby realizing the flipping of the watch strap 01. Users can wear the watch strap 01 in either the front or back as needed, making the wearable device not limited to one wearing method and improving the versatility of wearing wearable devices.

[0052] In one embodiment of this disclosure, one of the first headpiece 1 and the second headpiece 2 has a cavity, and the other is fixedly connected to a connecting portion 21. The connecting portion 21 extends into the cavity, and in the released state, the connecting portion 21 is rotatable within the cavity. In one example, the first headpiece 1 has a cavity, and the second headpiece 2 is fixedly connected to the connecting portion 21. In another example, the second headpiece 2 has a cavity, and the first headpiece 1 is connected to the connecting portion 21. This achieves a rotatable connection between the first headpiece 1 and the second headpiece 2.

[0053] In one embodiment of this disclosure, the headstock structure further includes an adjustment assembly 4. The first headstock 1 has a cavity, and the sidewall of the cavity has a connecting hole. The second headstock 2 includes a second headstock 2 and a connecting portion 21 fixedly connected by welding, integral connection, or other means. The connecting portion 21 extends into the cavity and is rotatable within the cavity. The first connecting assembly 3 is used to fix the connecting portion 21 and includes a first connecting shaft 31, a first elastic element 32, and first connecting heads 33 connected to both ends of the first connecting shaft 31. The first connecting shaft 31 passes radially through the connecting portion 21 and is located within the cavity. The first connecting heads 33 are axially movable along the first connecting shaft 31 and can engage with the connecting hole. The first elastic element 32 can apply a force to the first connecting heads 33 to move them toward the connecting hole. The adjustment assembly 4 includes an adjustment rod 41, which is disposed on the first headstock 1 and can push the first connecting head 33 axially into the cavity under the action of force.

[0054] It should be noted that there are two adjusting components 4, the first connecting component 3 is located between the two adjusting components 4, and the two adjusting components 4 are coaxially arranged; there are two connecting holes, one connecting hole can be engaged with one first connecting head 33, and the other connecting hole can be engaged with another first connecting head 33.

[0055] Thus, by applying force to the two adjusting rods 41, the adjusting rods 41 push the first connecting head 33 along the axial direction of the first connecting shaft 31 into the cavity, thereby disengaging the first connecting head 33 from the connecting hole. At this time, the second end piece 2 can be rotated, allowing the connecting part 21 to rotate in the cavity. After rotating the connecting part 21 180°, the force applied to the adjusting rods 41 is removed. Under the action of the first elastic member 32, the two first connecting heads 33 are pushed away from each other along the axial direction of the first connecting shaft 31, so that the first connecting heads 33 are engaged in the connecting hole, and the first connecting heads 33 push the adjusting rods 41 to reset, thereby fixing the connecting part 21. In the embodiments of this disclosure, by pushing the first connector 33 apart from the connector hole by adjusting the rod 41, the connector 21 can be released from fixation. During the rotation of the second end piece 2 by 180°, the watch strap 01 will be rotated by 180°, thereby realizing the flipping of the watch strap 01. The user can wear the watch strap 01 in the front or back as needed, so that the wearable device is not limited to one way of wearing it, and the diversity of wearing wearable devices is improved.

[0056] In one embodiment of this disclosure, the first headpiece 1 can be cubic, cylindrical, frustum-shaped, or other irregular geometric shapes, depending on the need and not limited herein. The connecting portion 21 can be cylindrical, spherical, ellipsoidal, or other irregular geometric shapes, depending on the need and not limited herein. The second headpiece 2 can be cylindrical, spherical, ellipsoidal, or other irregular geometric shapes, depending on the need and not limited herein.

[0057] In one embodiment of this disclosure, the first elastic element 32 may be a spring, torsion spring, elastic sheet, or other structure to push the first connector 33 to reset.

[0058] In one embodiment of this disclosure, see Figure 3 The first connecting shaft 31 is a hollow structure. A first connecting head 33 is slidably fitted to the end of the first connecting shaft 31, and at least partially located inside the first connecting shaft 31. A first elastic member 32 is located between the two first connecting heads 33. The end of the first connecting shaft 31 has a retaining ring, and the peripheral wall of the first connecting head 33 has a flared boss 34. When the first elastic member 32 pushes the first connecting head 33 to reset along the axial direction of the first connecting shaft 31, the flared boss 34 can abut against the retaining ring. Thus, by abutting against the retaining ring, the first connecting head 33 can be prevented from disengaging from the first connecting shaft 31, improving the stability and practicality of the connector structure. In other embodiments of this disclosure, the first connecting head 33 can be a hollow structure, and the first connecting head 33 can be sleeved on the end of the first connecting shaft 31.

[0059] In one embodiment of this disclosure, see Figure 3 The first headpiece 1 also has a chamber for accommodating the adjustment component 4; there are two chambers, with an empty cavity located between the two chambers, and the chambers are connected to the empty cavity through a connecting hole. At least a portion of the adjustment rod 41 is located in the chamber and can slide along the axial direction of the first connecting shaft 31 with the chamber. One end of the adjustment rod 41 near the first connecting shaft 31 can pass through the connecting hole and abut against the first connecting head 33. In this way, the adjustment rod 41 can move along the axial direction of the first connecting shaft 31 in the chamber under the action of force, so as to accommodate the adjustment rod 41, improve the compactness of the headpiece structure, and facilitate the miniaturization of the headpiece structure.

[0060] In one embodiment of this disclosure, see Figure 3 , Figure 7The adjusting rod 41 has an abutment 42 on the side near the first connecting shaft 31. The abutment 42 and the adjusting rod 41 can be fixedly connected by welding, integral connection, or other methods. The abutment 42 can pass through the connecting hole and abut against the first connecting head 33, and the diameter of the connecting hole is smaller than the diameter of the cavity. Thus, during the movement of the adjusting rod 41, the abutment 42 can slide along the axial direction of the connecting hole in the connecting hole, so that the abutment 42 pushes the first connecting head 33 to move, thereby facilitating the release of the fixed connection part 21. Because the diameter of the connecting hole is smaller than the diameter of the cavity, when the abutment 42 pushes the first connecting head 33 into the cavity, the side wall of the cavity can limit the adjustment rod 41, preventing the adjustment rod 41 from moving excessively, thus improving the practicality and reliability of the headstock structure.

[0061] In one embodiment of this disclosure, see Figure 3 The shape of the abutment 42 near the first connector 33 can be arc-shaped, and the shape of the first connector 33 near the abutment 42 can be arc-shaped. One of the abutment 42 and the first connector 33 can have a receiving hole, and the other can fit into the receiving hole, so as to prevent the abutment 42 and the first connector 33 from slipping and affecting the stability of the structure.

[0062] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 7 The adjusting assembly 4 also includes a spring element 43, which is located in the chamber and applies a force to the adjusting rod 41 in a direction away from the first connecting shaft 31. The spring element 43 can be a spring, torsion spring, elastic sheet, or other similar structure. Taking a spring as an example, the spring element 43 can be coaxially sleeved on the adjusting rod 41 or fixedly connected to the adjusting rod 41. In this way, the adjusting rod 41 can be reset by means of the spring element 43.

[0063] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 7 The adjusting assembly 4 also includes a retaining ring 44, which is coaxially fixed within the cavity and can be interference-fitted with the cavity. The adjusting rod 41 has a protrusion 45 on its peripheral wall, extending circumferentially along the adjusting rod 41. A spring element 43 can be located between the protrusion 45 and a side wall of the cavity near the first connecting shaft 31. The protrusion 45 is located between the retaining ring 44 and the first connecting shaft 31 and can abut against the side of the retaining ring 44 near the first connecting shaft 31. Thus, when the force applied to the adjusting rod 41 is removed, the spring element 43 pushes the protrusion 45 back to its original position, causing the adjusting rod 41 to reset synchronously. The abutment between the protrusion 45 and the retaining ring 44 prevents the adjusting rod 41 from disengaging from the cavity during the reset process, further improving the stability of the headstock structure.

[0064] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 9 A baffle 11 is fixedly connected to the side of the first headpiece 1 near the second headpiece 2. The baffle 11 has a notch 111. The connecting part 21 has an annular groove 211 on the side near the second headpiece 2. The edge of the notch 111 rotatably engages with the annular groove 211. Thus, when the second headpiece 2 is rotated after the connecting part 21 is released from its fixed position, the connecting part 21 can rotate within the notch 111, and the edge of the notch 111 is located within the annular groove 211. This allows the baffle 11 to block the connecting part 21, ensuring that the connecting part 21 can only rotate within the cavity, preventing it from dislodging from the cavity during rotation, and further improving the stability and reliability of the headpiece structure. See also... Figure 4 , Figure 8 By setting a notch 111 on the baffle 11, when installing the baffle 11, force can be applied to the adjusting component 4 to release the second head piece 2 from its fixed position, and then the second head piece 2 can be rotated 90° to expose the baffle 11 at the installation position of the first head piece 1. The edge of the notch 111 cooperates with the annular groove 211 to facilitate the installation of the baffle 11 at the installation position of the first head piece 1. The baffle 11 can be installed with the first head piece 1 by welding, threaded connection or other methods, which improves the installation convenience of the baffle 11.

[0065] In one embodiment of this disclosure, the first head piece 1 has a clearance groove on the side near the second head piece 2, and a positioning post is provided in the clearance groove. The baffle 11 has a positioning hole for engaging with the positioning post, and the baffle 11 can be installed in the clearance groove. Thus, the engagement of the positioning post and the positioning hole facilitates the positioning of the baffle 11, improving the installation efficiency and accuracy of the baffle 11. Furthermore, installing the baffle 11 in the clearance groove, through the engagement of the clearance groove and the baffle 11, improves the connection stability of the baffle 11 and also contributes to the miniaturization of the head piece structure.

[0066] In one embodiment of this disclosure, the second lead 2 has a receiving cavity on the side away from the connecting portion 21, and the sidewall of the receiving cavity has a snap-fit ​​hole. The lead structure also includes a second connecting component 5 disposed in the receiving cavity. The second connecting component 5 is used to connect the watch strap 01, and the watch strap 01 has a through hole through which the second connecting component 5 passes. The second connecting component 5 includes a second connecting shaft 51, a second elastic member 52, and second connecting heads 53 disposed at both ends of the second connecting shaft 51. The second connecting shaft 51 extends axially along the first connecting shaft 31, the second connecting heads 53 are movable axially along the second connecting shaft 51, the second connecting heads 53 can be engaged in the snap-fit ​​hole, and the second elastic member 52 can apply a force to the second connecting heads 53 to move them away from the second connecting shaft 51. Thus, by having the second connecting component 5 pass through the watch strap 01, the second connecting heads 53 extend out of the through hole and engage in the snap-fit ​​hole, so as to facilitate the connection between the watch strap 01 and the lead structure.

[0067] In one embodiment of this disclosure, see Figure 3 , Figure 4 The second connecting shaft 51 is a hollow structure. The second connecting head 53 is slidably fitted to the end of the second connecting shaft 51, and at least partially located inside the second connecting shaft 51. A second elastic element 52 is located between the two second connecting heads 53. The second elastic element 52 can be a spring, torsion spring, elastic sheet, or similar structure. The end of the second connecting shaft 51 extends towards its own axis, and the end of the second connecting head 53 away from the second elastic element 52 extends away from its own axis to prevent the second connecting head 53 from disengaging from the second connecting shaft 51. In other embodiments of this disclosure, the second connecting head 53 can be a hollow structure, and the second connecting head 53 can be sleeved on the end of the second connecting shaft 51.

[0068] In one embodiment of this disclosure, the peripheral wall of the second connector 53 is provided with at least one annular boss, and the number of annular bosses can be one, two, three, etc. When the end of the second connector 53 away from the second elastic member 52 extends into the snap-fit ​​hole, the annular boss can abut against the side wall of the receiving cavity to further improve the stability of the headstock structure.

[0069] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5The headpiece structure also includes a third connecting component 6 for connection with the watch case. The third connecting component 6 passes through the first headpiece 1 along the axial direction of the first connecting shaft 31. The first headpiece 1 has a through hole for placing the third connecting component 6, and the watch case has a mating hole. The third connecting component 6 includes a third elastic element 61 and a third connecting head 62. The third connecting head 62 extends out of the first headpiece 1 and can mate with the mating hole. There are two third connecting heads 62. The third elastic element 61 is located between the two third connecting heads 62 and is located inside the first headpiece 1. It can apply a force to the third connecting head 62 to move it toward the watch case. The third elastic element 61 can be a spring, torsion spring, elastic sheet, or other structure. In this way, the third connecting head 62 and the third elastic element 61 facilitate the detachable connection between the first headpiece 1 and the watch case, which is beneficial for the subsequent maintenance of the wearable device.

[0070] In one embodiment of this disclosure, see Figure 3 , Figure 4 The through hole has an interference fit with a limiting ring 63. The third connector 62 has an expansion portion 621 at one end near the third elastic member 61. The expansion portion 621 is located between the limiting ring 63 and the third elastic member 61 and can abut against the limiting ring 63. In this way, the third connector 62 can be prevented from disengaging from the first head piece 1.

[0071] In one embodiment of this disclosure, see Figures 1-5 At least one third connector 62 has a protrusion 622, which can be cylindrical, conical, spherical, ellipsoidal, or an irregular geometric shape. The protrusion 622 extends out of the first end piece 1, which has a clearance hole for avoiding the protrusion 622. The clearance hole communicates with the through hole, and the protrusion 622 can drive the third connector 62 to move axially along the first connecting shaft 31 within the clearance hole under the action of external force. In this way, force can be applied to the protrusion 622, causing the third connector 62 to compress the third elastic member 61, thereby disengaging the third connector 62 from the mating hole of the watch case, facilitating the quick disassembly and installation of the end piece structure and the watch case.

[0072] The working principle of the head-particle structure according to the present disclosure will be explained below.

[0073] When it is necessary to flip the watch strap 01, the user can press the two adjusting levers 41, causing the adjusting levers 41 to move the two abutments 42 closer together. The abutments 42 push the two first connectors 33 closer together until the two first connectors 33 disengage from the connecting holes and are located in the cavity. At this time, the first elastic element 32 and the elastic element 43 are compressed, releasing the fixation of the connecting part 21 (see...). Figure 4Then, the person continuously presses the adjusting lever 41 and rotates the second end piece 180°. The second end piece 2 drives the connecting part 21 to rotate 180°. At this time, the watch strap 01 also rotates 180° with the second end piece 2. Then, the adjusting lever 41 is released. Under the action of the first elastic element 32 and the elastic element 43, the two first connecting heads 33 move away from each other until the protrusion 45 abuts against the retaining ring 44. Thus, the first connecting heads 33 and the adjusting lever 41 have completed their reset, so as to fix the connecting part 21 (see...). Figure 3 Users can choose to display the front or back of the watch strap 01 according to their personal preferences, which increases the versatility of wearing the wearable device and enriches the user experience.

[0074] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
