Description

Technical Field

[0001] This application relates to the technical field of wearable accessories, and more particularly to a watch link for a watch strap, a watch strap, and a watch. Background Technology

[0002] Currently, wearable devices such as smartwatches and traditional wristwatches are playing an increasingly important role in people's daily lives. However, a significant problem that urgently needs to be addressed in the design of watch straps on the market is insufficient breathability. Considering the way watch straps contact the wrist, most straps, to ensure a secure fit, have a large area of ​​their back directly against the wrist skin. When users wear such straps for extended periods, the wrist area is essentially covered by an impermeable "barrier," preventing effective air circulation and hindering the rapid evaporation of sweat. Over time, sweat accumulates on the skin surface, making the wrist area damp and hot. This damp and hot environment not only causes significant discomfort but also poses a potential threat to skin health. Therefore, improving the breathability of watch straps and reducing the lack of breathability caused by the large contact area between the strap and the wrist, thereby enhancing user comfort and preventing adverse symptoms such as sweating and rashes from prolonged wear, has become a key technical problem that urgently needs to be solved in the design and manufacturing of watch straps. Summary of the Invention

[0012] Optionally, the two connecting ears and one side of the intermediate connecting portion form a C-shaped connecting groove; the side of the intermediate connecting portion facing away from the connecting groove forms a connecting tongue for inserting into the connecting groove of an adjacent watch grain.

[0013] The pin hole includes a first pin hole located on the connecting ear and a second pin hole located on the connecting tongue. The upper cover and the base cover the connecting ear and the connecting tongue respectively, so that the upper cover and the base combine to form the first pin hole and the second pin hole.

[0014] Optionally, the base includes a base plate and two side baffles protruding from the base plate, the two side baffles being located on opposite sides of the two connecting ears, and the top cover being located between the two side baffles.

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] Currently, wearable devices such as smartwatches and traditional wristwatches are playing an increasingly important role in people's daily lives. However, a significant problem that urgently needs to be addressed in the design of watch straps on the market is insufficient breathability. Considering the way watch straps contact the wrist, most straps, to ensure a secure fit, have a large area of ​​their back directly against the wrist skin. When users wear such straps for extended periods, the wrist area is essentially covered by an impermeable "barrier," preventing effective air circulation and hindering the rapid evaporation of sweat. Over time, sweat accumulates on the skin surface, making the wrist area damp and hot. This damp and hot environment not only causes significant discomfort but also poses a potential threat to skin health. Therefore, improving the breathability of watch straps and reducing the lack of breathability caused by the large contact area between the strap and the wrist, thereby enhancing user comfort and preventing adverse symptoms such as sweating and rashes from prolonged wear, has become a key technical problem that urgently needs to be solved in the design and manufacturing of watch straps.

[0034] To overcome the above technical problems, such as Figures 4-6 As shown, this application embodiment provides a watch bead 10 for a watch strap 100, including a watch bead body. The watch bead body includes a middle connecting part 1 and two opposite connecting lugs 2 connected to the middle connecting part 1. An airflow exchange space 3 is provided on the middle connecting part 1, and the airflow exchange space 3 is located on the side of the middle connecting part 1 that is close to the wrist.

[0035] The main body of the watch beads consists of a central connecting part 1 and two opposite connecting lugs 2. This structural design allows the watch beads 10 to be stably connected and function in the watch strap 100. The central connecting part 1, as the core part of the watch beads 10, plays a supporting and load-bearing role; the connecting lugs 2 are responsible for connecting with other watch beads 10 or watch strap 100 components to ensure the integrity and continuity of the watch strap 100.

[0036] An airflow exchange space 3 is located in the middle connecting part 1. When worn, the connecting ears 2 on both sides contact the wrist to form support, allowing the middle connecting part 1 to form a breathable space between itself and the surface of the wrist. This structure maintains the stability of wearing the garment while enhancing breathability.

[0037] In the watch bead 10 structure for watch strap 100 provided in this application embodiment, an airflow exchange space 3 is provided on the side of the watch bead body that is close to the wrist. The airflow exchange space 3 is the core innovation of the watch bead 10 structure design. It is a groove structure opened at a specific position on the surface of the watch bead 10 that contacts the wrist. The shape, depth, width and distribution of the airflow exchange space 3 can be designed according to actual needs. For example, it can be a regular strip groove, a wavy groove, or an irregular patterned groove, etc. Its purpose is to form an airflow channel between the watch bead 10 and the wrist.

[0038] When the watch strap 10 is fitted with a watch link 10 having an airflow exchange space 3, the airflow exchange space 3 creates a certain space between the watch link 10 and the wrist. During wear, the sweat produced on the wrist has more room to evaporate due to the presence of the airflow exchange space 3. At the same time, the airflow exchange space 3 promotes air circulation between the watch link 10 and the wrist. External air can enter the area between the watch link 10 and the wrist through the airflow exchange space 3, carrying away the water vapor and heat generated by the evaporation of sweat, thereby preventing the formation of a closed and humid environment in this area. This air circulation mechanism effectively improves the breathability of the part of the watch strap 100 that contacts the wrist, reducing the risk of sweaty wrists and rashes.

[0039] In the watch strap 100 structure using the watch beads 10 of this embodiment, the watch strap 100 is typically formed by connecting multiple watch beads 10 sequentially through connecting structures (such as wires, buckles, connecting pins 20, etc.) to form a strap-like structure that can wrap around the wrist. Specifically, during the assembly process of the watch strap 100, these watch beads 10 with airflow exchange space 3 can be connected to other watch beads 10 through wires or other connection methods, just like ordinary watch beads 10. Their installation position and number can be adjusted according to the design of the watch strap 100 and user needs. It is possible that all the watch beads 10 on the watch strap 100 adopt this design with airflow exchange space 3, or that some of the watch beads 10 adopt this design and are used in combination with other ordinary watch beads 10.

[0040] like Figures 1-3Taking a common metal watch band 100 as an example, the metal watch band 100 is usually composed of multiple metal links 10 connected by metal pins. The links 10 of this application can be installed in the following manner: the link body is designed to conform to the overall style and size requirements of the watch band 100, and can be square, round, or other shapes that conform to the overall aesthetics of the watch band 100. Preferably, the airflow exchange space 3 is located on the side of the link body closest to the wrist, and its direction can be consistent with the extension direction of the watch band 100 to ensure smooth airflow. During the assembly of the watch band 100, multiple links 10 with airflow exchange spaces 3 are arranged in a specific order and connected sequentially by metal pins. After installation, the watch band 100 can bend normally and conform to the wrist, while the airflow exchange space 3 always remains on the side closest to the wrist, providing ventilation space for the wrist.

[0041] In summary, based on the watch strap 10 provided in this embodiment, the airflow exchange space 3 effectively breaks the sealed state between the watch strap 10 and the wrist, allowing air to circulate freely between them. This helps to remove sweat and heat generated by the wrist in a timely manner, keeping the wrist dry and comfortable, greatly reducing the risk of sweaty wrists and rashes caused by long-term wear, and greatly improving the user's comfort when wearing the watch strap 100, thereby increasing the user's satisfaction and loyalty to the product.

[0042] In one embodiment, the airflow exchange space 3 extends through the front and back along the length of the strap 100.

[0043] In this embodiment, the airflow exchange space 3, located on the side of the watch strap 100 close to the wrist, extends along the length of the strap 100. This means that when multiple watch straps 10 are connected in series, the airflow exchange space 3 is not a localized, closed groove, but rather extends from one end of the strap 100 to the other, forming a continuous channel. When the strap 100 is worn on the wrist, because the airflow exchange space 3 extends along the length of the strap 100, external air can smoothly enter the area between the strap 100 and the wrist from one end of the strap 100 along the airflow exchange space 3 and flow out from the other end. This continuous airflow forms an effective ventilation cycle, like building an "air highway" between the strap 100 and the wrist, which can quickly remove the moisture and heat generated by the evaporation of sweat from the wrist.

[0044] In this embodiment, compared with a non-permeable or partially breathable watch strap 100, the airflow exchange space 3 that is permeable from front to back can greatly increase the area and efficiency of air circulation. No matter what position the wrist is in, air can flow freely in the airflow exchange space 3, ensuring that all areas of the watch strap 100 in contact with the wrist can be well ventilated, thereby significantly improving the breathability and effectively reducing the possibility of the wrist getting sweaty.

[0045] In one embodiment, the airflow exchange space 3 is a V-shaped groove or an arc-shaped groove.

[0046] The V-groove has a V-shaped cross-section with two sloping sides. This structure creates a noticeable indentation in the airflow exchange space 3 on the wrist side of the watch strap 10. The opening is relatively wide, while the bottom is narrower. The depth and angle of the V-groove can be adjusted according to the design requirements of the watch strap 100; the greater the depth and the sharper the angle, the more pronounced the indentation. Similarly, the arc-shaped groove also has a relatively wide opening and a narrow bottom.

[0047] The larger opening and air-guiding effect allow the V-shaped groove to quickly introduce and expel air, greatly improving the breathability of the strap. During exercise or in high-temperature environments, it can quickly remove heat and sweat from the wrist, effectively reducing the risk of sweaty wrists. Furthermore, the edges of the grooves do not form sharp edges, optimizing wearing comfort.

[0048] In one embodiment, decorative stripes are provided on the side of the intermediate connecting portion 1 facing away from the airflow exchange space 3.

[0049] The side of the middle connecting part 1 that faces away from the airflow exchange space 3 is the surface that looks when worn. Decorative stripes are set on this surface to optimize the product's appearance and enhance its attractiveness.

[0050] In one embodiment, combined with Figures 2-4 The two connecting ears 2 and one side of the intermediate connecting part 1 form a C-shaped connecting groove 21; the side of the intermediate connecting part 1 facing away from the connecting groove 21 forms a connecting tongue 11 for inserting into the connecting groove 21 of the adjacent watch grain 10;

[0051] The depth of the connecting groove 21 is greater than the protrusion length of the connecting tongue 11, so that after two adjacent watch beads 10 are connected, a vent hole 4 is formed between the two adjacent watch beads 10.

[0052] In this embodiment, the main body of the watch beads consists of a central connecting part 1 and connecting ears 2 located on two opposite sides. The central connecting part 1 provides core support, while the connecting ears 2 are responsible for connecting the watch beads 10. The two connecting ears 2 and one side of the central connecting part 1 together form a C-shaped connecting groove 21. This C-shaped structure provides a specific space and method for connecting the watch beads 10. The side of the central connecting part 1 facing away from the connecting groove 21 forms a connecting tongue 11. The shape of the connecting tongue 11 is adapted to the connecting groove 21 and is used to insert into the connecting groove 21 of adjacent watch beads 10 to achieve the connection between the watch beads 10. When adjacent watch beads 10 are connected, the connecting tongue 11 of one watch bead 10 is inserted into the connecting groove 21 of another watch bead 10. Through this insertion method, multiple watch beads 10 can be connected sequentially to form a complete watch strap 100. The cooperation between the connecting groove 21 and the connecting tongue 11 ensures the stability and reliability of the connection between the watch beads 10, allowing the watch strap 100 to bend normally and fit the wrist.

[0053] Importantly, because the depth of the connecting groove 21 is greater than the protruding length of the connecting tongue 11, a certain gap will appear at the connection point of adjacent watch links 10 after they are connected. This gap forms a vent 4. The presence of the vent 4 allows external air to enter the interior of the watch strap 100 through the vent 4, forming an air circulation channel between the watch links 10 and the wrist. The formation of the vent 4 significantly improves the breathability of the watch strap 100. Air can circulate freely inside the watch strap 100 through the vent 4, carrying away sweat and heat generated by the wrist, effectively reducing the possibility of sweaty wrists, keeping the wrist area dry and comfortable, and improving the user's experience of wearing the watch strap 100.

[0054] In one embodiment, reference is made to Figure 7 The main body of the watch grain includes a base 7 and a top cover 6. The base 7 is provided with a first semi-cylindrical groove 71, and the top cover 6 is provided with a corresponding second semi-cylindrical groove 61. The top cover 6 covers the base 7, and the first semi-cylindrical groove 71 and the second semi-cylindrical groove 61 combine to form a pin hole 5 for accommodating the connecting pin 20.

[0055] Each watch link 10 has two pin holes 5. One pin hole 5 passes through the connecting lug 2, allowing the connecting pin 20 to connect the connecting lug 2 of the watch link 10 to other components (such as the connecting tongue 11 of adjacent watch links 10) through this pin hole 5. The other pin hole 5 passes through the connecting tongue 11 and is used to engage with the pin hole 5 on the connecting lug 2 of the adjacent watch link 10 to achieve the connection between the watch links 10. Between two adjacent watch links 10, the connecting lug 2 of the preceding watch link 10 and the connecting tongue 11 of the following watch link 10 are connected by the connecting pin 20. This connection method allows the watch strap 100 to bend and stretch flexibly to adapt to the shape and movement of the wrist.

[0056] The separate design of the base 7 and top cover 6 makes the assembly of the watch links 10 more convenient. During the production process, the base 7 and top cover 6 can be machined separately first, and then assembled together, improving production efficiency. Specifically, machining the semi-cylindrical groove is less difficult than machining the through hole. At the same time, if the watch band 100 is damaged, the watch links 10 can be easily disassembled for repair or replacement, reducing maintenance costs.

[0057] Preferably, the base 7 and the top cover 6 can be fixed by a snap fastener, or by means of glue application, welding, etc.

[0058] In addition, the modular structure allows for the use of different colored materials to create the base 7 and the top cover 6, providing a richer appearance and increasing its appeal to users.

[0059] In one embodiment, the two connecting ears 2 and one side of the intermediate connecting part 1 form a C-shaped connecting groove 21; the side of the intermediate connecting part 1 facing away from the connecting groove 21 forms a connecting tongue 11 for inserting into the connecting groove 21 of the adjacent watch grain 10.

[0060] The pin hole 5 includes a first pin hole 51 located on the connecting ear 2 and a second pin hole 52 located on the connecting tongue 11. The upper cover 6 and the base 7 respectively cover the connecting ear 2 and the connecting tongue 11, so that the upper cover 6 and the base 7 together form the first pin hole 51 and the second pin hole 52.

[0061] When adjacent watch parts 10 are connected, the connecting tongue 11 of one watch part 10 is inserted into the C-shaped connecting groove 21 of another watch part 10. At the same time, the first pin hole 51 of the connecting ear 2 and the second pin hole 52 of the connecting tongue 11 are precisely aligned and fixed through the connecting pin 20. This connection method utilizes the shape matching of the connecting groove 21 and the connecting tongue 11, as well as the size matching of the pin hole 5 and the connecting pin 20, to ensure the stability and reliability of the connection between the watch parts 10.

[0062] The pin hole 5 is divided into two parts, which are machined on the upper cover 6 and the base 7 respectively. Compared with machining the pin hole 5 on the complete surface material body, the complexity and difficulty of machining are reduced, and the machining accuracy and efficiency are improved.

[0063] In one embodiment, reference is made to Figure 7 The base 7 includes a base 7 plate and two side baffles 72 protruding from the base 7 plate. The two side baffles 72 are respectively located on the opposite sides of the two connecting ears 2, and the upper cover 6 is located between the two side baffles 72.

[0064] In this embodiment, the base plate 7 serves as a basic support structure, providing a stable bearing platform for the entire watch grain 10. The two side baffles 72 are located on opposite sides of the two connecting ears 2, creating a specific spatial positional relationship between the side baffles 72 and the connecting ears 2. The top cover 6 is located between the two side baffles 72, which limit and position the top cover 6, ensuring accurate positioning of the top cover 6 and the base 7 during assembly, and also enhancing the overall structural stability of the watch grain 10.

[0065] Additionally, refer to Figure 1 When worn, the side of the connecting ear 2 facing away from the connecting tongue 11 (i.e. the outer side of the connecting ear 2) is the outer side of the watch strap 100, which is the side that the user can easily observe directly. This side uses the complete surface of the side panel 72 as the appearance surface to avoid forming splicing gaps on this side and optimize the appearance of the side.

[0066] Secondly, such as Figure 1 As shown, this embodiment provides a watch strap 100, including:

[0067] Multiple particles as described above, such as 10;

[0068] Multiple connecting pins 20 connect multiple of the watch particles 10 in series.

[0069] In the specific structure, the connecting lug 2 on the watch links 10 and the middle connecting part 1 form a C-shaped connecting groove 21. The middle connecting part 1 forms a connecting tongue 11 on the side facing away from the connecting groove 21. This structure allows the watch links 10 to achieve initial positioning and connection through the connecting tongue 11 and the connecting groove 21. Multiple connecting pins 20 connect multiple watch links 10 in sequence. The connecting pins 20 are inserted into the pin holes 5 on the watch links 10. Through the cooperation of the pins and holes, adjacent watch links 10 are firmly connected together to form a complete watch strap 100.

[0070] As mentioned above, in the structure of the watch strap 100 in this embodiment, by providing an airflow exchange space 3 on the side of the watch beads 10 close to the wrist, and by forming ventilation holes 4 between the watch beads 10 through a specific structure, the watch strap 100 can be guaranteed to have good breathability, keeping the wrist area dry and comfortable, and reducing discomfort caused by sweat accumulation.

[0071] Thirdly, a watch is provided, including the watch strap 100 as described above.

[0072] Similarly, the watch in this embodiment has advantages such as good breathability and comfortable wear.
