Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and further to an adjustable length headstock structure, a watch strap, and a watch. Background Technology

[0002] With the rapid development of technology, various smart wearable devices are permeating all aspects of people's lives, bringing tremendous changes to their daily experiences. Wearable devices are not merely hardware devices; they achieve their powerful functions through software support, data interaction, and cloud interaction. Their applications are very broad, including healthcare, fitness, and communication. For example, watches are no longer limited to simply telling time. By embedding intelligent hardware and running a smartphone operating system connected to the network, they can perform various functions such as making calls, sending text messages, emails, viewing photos, and listening to music and videos. Smartwatches are an extension and expansion of smartphone functions, bringing great convenience to people's daily lives.

[0003] When wearing a smartwatch, the case should fit snugly against the wrist for a secure fit and improved wearing experience. However, traditional watch straps are generally divided into buckle straps and separate chain straps. Buckle straps require disassembly and reassembly for each length adjustment, which is cumbersome and results in a poor user experience. Separate chain straps, on the other hand, have fixed-length individual links, requiring users to purchase additional parts or remove excess links for adjustment. This process is complex and may not always achieve the desired length, impacting the performance of the smartwatch.

[0004] Therefore, the inventors hope to solve the technical problem of how to further adjust the length of the watch strap within a small range without affecting the original adjustment method, so as to obtain a watch strap with a better wearing experience and a comfortable wearing effect.

Detailed Implementation

[0038] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0040] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In one embodiment, refer to the appendix to the specification. Figures 1 to 7 The present invention provides a length-adjustable headstock structure, comprising: a first headstock 1 and a second headstock 2. One end of the first headstock 1 forms a slot 11, and a toothed groove structure 12 is provided in the slot 11. The second headstock 2 is disposed in the slot 11 and can move along the length direction of the first headstock 1. The second headstock 2 is provided with a damping element 21, which is adapted to and connected to the toothed groove structure 12. When the second headstock 2 is driven to move relative to the first headstock 1, the damping element 21 can be placed in different grooves of the toothed groove structure 12, so that the second headstock 2 stops at different positions.

[0044] In this embodiment, the second end piece 2 is slidably disposed in the slot 11 of the first end piece 1. The first end piece 1 is provided with a toothed groove structure 12, and the second end piece 2 is provided with a damping element 21. The damping element 21 can be placed in different grooves of the toothed groove structure 12, so that the second end piece 2 stops at different positions. When the second end piece 2 is driven to move away from the first end piece 1 to the farthest distance, that is, when the second end piece 2 is at its maximum extension position, it is convenient for the user to put on or take off the watch. After putting on the watch, driving the second end piece 2 to move closer to the first end piece 1 can shorten the length of the watch strap, and the length of the watch strap can be freely adjusted according to the thickness of the user's arm.

[0045] The novel and ingenious structure of this adjustable end link allows for automatic adjustment of the strap length within a small range without affecting the original strap adjustment method. This results in a better wearing experience and a more comfortable wearing effect. It also has the advantages of easy disassembly and assembly, convenient adjustment, and compatibility with traditional chain straps and soft rubber straps.

[0046] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3The toothed structure 12 includes several parallel-arranged protrusions 121, with a groove 122 formed between adjacent protrusions 121. The protrusions 121 are triangular or arc-shaped. By setting multiple staggered grooves in the toothed structure 12, the second end piece 2 generates a damping feel during movement and can hover at each groove position, enhancing the user's operating experience. Of course, the protrusions 121 can also be other shapes, as long as they can cooperate with the damping element 21 to achieve a damping feel.

[0047] Furthermore, the toothed structure 12 also includes reinforcing ribs 123, which are disposed at the ends of several protruding teeth 121, with each protruding tooth 121 having its end integrally formed with the reinforcing rib 123. Alternatively, reinforcing ribs 123 can be provided at both ends of the protruding teeth 121. By providing reinforcing ribs 123, the strength of the toothed structure 12 can be improved, preventing cracks from forming during long-term use and extending its service life.

[0048] Reference manual attached Figures 4 to 7 The damping element 21 includes a fixing section 211, a connecting section 212, and an elastic protrusion 213. The fixing section 211 is connected to the second end piece 2, and the fixing section 211 is connected to the elastic protrusion 213 through the connecting section 212. The elastic protrusion 213 can be adapted to be engaged in different grooves 122 of the toothed structure 12. A damping groove 22 is provided on the side of the second end piece 2 near the first end piece 1. At least one fixing post 221 is provided at the bottom of the damping groove 22. The fixing section 211 is provided with a fixing hole 2111, and the fixing post 221 is adapted to be inserted into the fixing hole 2111, so that the damping element 21 is fixedly or detachably connected to the second end piece 2. For example, the fixing post 221 is a hot-melt post, and the damping element 21 is fixedly connected to the second end piece 2 through the hot-melt post. Of course, glue or snap-fit ​​structures can also be used.

[0049] For example, refer to the appendix to the instruction manual. Figures 4 to 7 Two fixing posts 221 are provided, and the two fixing posts 221 are fixed at one end of the damping groove 22 at intervals. The connecting section 212 is bent so that the elastic protrusion 213 extends to the upper side of the damping groove 22 near the fixing post 221 and is adapted to connect with the groove 122 of the toothed structure 12. The fixing section 211, the connecting section 212 and the elastic protrusion 213 are integrally formed. For example, the damping element 21 is made of steel sheet. The bent connecting section 212 provides elasticity, so that the damping element 21 forms an irregularly shaped spring sheet. The spring sheet will deform under force during movement and is always in a state of force, thereby providing a pulling damping feel.

[0050] For example, refer to the appendix to the instruction manual. Figure 8 , Figure 9Two fixing posts 221 are provided, and the two fixing posts 221 are fixed at one end of the damping groove 22 at intervals. The connecting section 212 is inclined so that the elastic protrusion 213 extends to the upper side of the other end of the damping groove 22 and is adapted to connect with the groove 122 of the toothed structure 12. The fixing section 211, the connecting section 212 and the elastic protrusion 213 are integrally formed. For example, the damping element 21 is made of steel sheet. The inclined connecting section 212 provides elasticity, so that the damping element 21 forms an irregularly shaped spring sheet. The spring sheet will be deformed by force during the movement and is always in a state of force, thereby providing a pulling damping feel.

[0051] It should be noted that the specific structures of the toothed structure 12 and the damping element 21 are described with reference to the accompanying drawings in the specification. In actual use, the structures of the toothed structure 12 and the damping element 21 can be set according to actual needs. This is only for better illustrating the present invention and should not constitute a limitation on the present invention.

[0052] In one embodiment, refer to the appendix to the specification. Figures 4 to 6 The slot 11 has guide grooves 13 on both sides, extending along the length of the first end piece 1. The second end piece 2 has two spring bar grooves 23 on the side closest to the first end piece 1. Spring bars 231 are fitted into the spring bar grooves 23, with their telescopic ends inserted into the guide grooves 13 and able to move along the length of the guide grooves 13. By using guide grooves 13 and spring bars 231 for guidance, the movement of the second end piece 2 relative to the first end piece 1 is smoother and more stable. Simultaneously, spring bars 231 can also stop the movement, preventing the second end piece 2 from dislodging and causing product malfunction. Spring bars 231 have the advantage of easy installation and removal. Of course, other structures, such as sliding rods or sliders, can also be used to connect with the guide grooves 13.

[0053] Further, refer to the attached instruction manual. Figure 3 , Figure 6 The first end link 1 is provided with a first connecting part 14, which is located at the end of the first end link 1 away from the slot 11. The first connecting part 14 is used to connect with the watch body, watch strap, or watch links. The second end link 2 is provided with a second connecting part 24, which is located at the end of the second end link 2 away from the first end link 1. The second connecting part 24 is used to connect with the watch body, watch strap, or watch links.

[0054] According to another aspect of the present invention, the present invention further provides a watch strap, including the length-adjustable end link structure described in any one of the above, and further including:

[0055] Multiple watch links are connected in sequence, with the second watch link 2 connected to the first watch link to form a chain-like watch strap. It can be used in wearable devices such as mechanical watches, electronic watches, smart watches, and smart bracelets.

[0056] Alternatively, a soft rubber strip, wherein the second end piece is connected to the end of the soft rubber strip to form a soft rubber watch strap, which can be applied to wearable devices such as mechanical watches, electronic watches, smart watches, and smart bracelets.

[0057] In the field of watch straps, the connection between the end links and the soft rubber strap is a common technique used in the field, which is to fix them by means of spring bars or the like. The installation through holes are shown in the figure. They can also be set according to common knowledge in the field, so they will not be described in detail here.

[0058] According to another aspect of the present invention, the present invention further provides a watch, including the watch strap described above, and also including a watch body, the watch body being connected to the first end link 1.

[0059] In this invention, the product is easy to assemble and can be adjusted after wearing. Pulling the second end piece 2 will extend it, and pushing the second end piece 2 will shorten it. The operation is convenient and the interactivity is better. The brand-new watch strap adjustment mechanism optimizes the adjustment operation feel and improves convenience.

[0060] In the watch industry, the use of interlocking links and spring bars to fix the watch body is a common technique. The installation through-hole is shown in the figure, but it can also be set according to common knowledge in the field, so it will not be described in detail here.

[0061] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0062] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model.
