Description

Technical Field

[0001] This utility model relates to the field of watch technology, and in particular to a watch strap structure and a watch. Background Technology

[0002] A watch strap is a structure used to restrain the watch on a consumer's wrist. Depending on the material, watch straps are divided into steel straps, leather straps, and cord straps. Among them, steel straps are widely used due to their long service life and the ability to adjust the strap length by adjusting the clasp. Currently, steel straps on the market often use a double-press butterfly clasp connection. The length of the strap can be increased or decreased by opening or closing the butterfly clasp, allowing the watch to be easily worn and securely fastened on the user's wrist. However, in this type of strap structure, the traditional assembly method of the strap end and the double-press butterfly clasp is an overlapping arrangement. This assembly method makes the entire strap thicker at the clasp, affecting the watch's appearance and hindering the design of a thinner strap. Furthermore, the overlapping of the clasp and the strap end causes the part of the strap adjacent to the clasp to lift up, resulting in insufficient fit between the strap and the user's wrist, thus affecting the wearing experience. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Example 1 Please see Figure 1 This utility model discloses a watch strap structure that can reduce the thickness of the connection between the clasp and the end link, thereby improving the wearing comfort of the watch. The strap structure includes a clasp 100 and a first strap 200 and a second strap 300 located on opposite sides of the watch head and respectively connected to the watch head. The ends of the first strap 200 and the second strap 300, respectively, away from the watch head, engage with the clasp 100. This allows the length of the entire strap structure to be adjusted by unfolding and folding the clasp 100, enabling the watch to be worn on the user's wrist or easily removed from the user's wrist when the strap length increases. The first strap 200 has a first end link 210 facing away from the watch head, and the second strap 300 has a second end link 310 facing away from the watch head. The first end link 210 and the second end link 310 serve as the connection points between the first strap 200 and the second strap 300 and the clasp 100. It should be noted that in practical applications, this watch strap structure can not only be used to connect the watch head, but also to connect other wearable products, that is, it can be used as a connector for other wearable products (such as handicrafts or smart products).

[0018] Please combine Figure 2-5The watch clasp 100 includes a clasp cover assembly and a clasp frame 110. The clasp cover assembly includes two clasp covers 120, which are correspondingly disposed at the ends of the first tail link 210 and the second tail link 310. The rear end of the clasp cover 120 is hinged to the end of the first tail link 210 or the end of the second tail link 310. The lower surface of the clasp cover 120 has a first groove 121 that penetrates the front and rear end faces of the clasp cover 120. In this embodiment, the clasp cover 120 can be regarded as an extended tail link at the ends of the first tail link 210 and the second tail link 310, which is used to cover the structure of the clasp frame 110 after folding, so as to reduce the impact of the clasp frame 110 on the shape of the watch strap structure. The rear end of the clasp 120 refers to the end of the clasp 120 that mates with the adjacent first stud 210 or second stud 310, and the front end of the clasp 120 refers to the end of the clasp 120 that connects to the clasp holder 110. The lower surface of the clasp 120 refers to the side of the clasp 120 facing the user's wrist when the watch is worn, and correspondingly, the upper surface of the clasp 120 refers to the side of the clasp 120 facing away from the user's wrist when the watch is worn. The clasp holder 110 is located below the two clasps 120 and is housed in the first groove 121. That is, when the watch is worn, the clasp holder 110 is located between the clasp 120 and the user's wrist, so that the clasp holder 110 is jointly covered by the clasp 120 and the user's wrist. At the same time, by having the clasp holder 110 housed in the first groove 121, which represents the overlapping of the clasp 100 and the stud, the thickness of the connection between the clasp 100 and the stud can be effectively reduced, which is beneficial for the thinner design of the watch strap structure. The buckle 110 includes a frame 111, two wing plates 112 disposed at both ends of the frame 111 along the length direction of the frame 111 (i.e. the length direction of the watch strap structure), and two buttons 113 disposed on both sides of the frame 111 along the width direction of the frame 111 (i.e. the width direction of the watch strap structure). In this embodiment, the lower surface of the frame 111 is an arc surface so that the frame 111 fits the user's wrist when the watch is worn. One end of the wing plate 112 is hinged to the end of the frame 111 and can rotate to move closer to or away from the middle of the frame 111. The other end of the wing plate 112 is hinged to the front end of the corresponding clasp 120 above it. It can also be understood that each end of the frame 111 is hinged to a wing plate 112, and the wing plate 112 is further hinged to the clasp 120. In this way, when the clasp frame 110 is folded, the length of the clasp 100 (i.e. the dimension of the clasp frame 110 along the length of the watch strap structure) is the length of the frame 111. When the clasp frame 110 is unfolded, the length of the clasp 100 is the sum of the length of the frame 111, the length of the two wing plates 112, and the length of the two clasps 120, so as to reduce the difficulty of taking the watch off the user's wrist or putting it on the user's wrist.Button 113 slides along the width of frame 111 and is elastically connected. This elastic connection allows button 113 to slide relative to frame 111 along its width after the pressure applied to it is released, thus resetting the button and preparing it for the next press. A first engaging portion is provided on the wing plate 112, and a second engaging portion 114 is provided on button 113 near the middle of frame 111. The second engaging portion 114 engages with the first engaging portion when the end of wing plate 112 rotates to the middle of frame 111, and disengages from the first engaging portion when both buttons 113 are pressed. In other words, in this embodiment, pressing button 113 causes the second engaging portion 114 to move along the width of frame 111, adjusting the relative position between the first and second engaging portions. Thus, when the second fastening part 114 is fastened to the first fastening part, the wing plate 112 and the frame 111 can be locked, preventing the watch from falling off the user's wrist because the wing plate 112 lifts off the frame 111 on its own after the watch is worn; when the second fastening part 114 is released from the first fastening part by the action of the button 113, the constraint of the second fastening part 114 on the first fastening part is released, and the wing plate 112 is pulled to the frame 111 by the weight of the watch head and the watch strap or by the action of external pulling force, thereby realizing the unfolding of the watch buckle 100.

[0019] In this embodiment, the first tail piece 210 and the second tail piece 310 have the same structure and are symmetrically arranged at both ends of the buckle 100. The following description only describes the structure of the first tail piece 210 to illustrate the way it engages with the buckle cover 120. The structure of the second tail piece 310 can be referred to the description of the first tail piece 210. Specifically, please refer to... Figure 2 as well as Figure 6-8 The rear end of the first tail piece 210 (the end of the first tail piece 210 away from the cover 120) has a first protrusion 211 that inserts into a groove on an adjacent belt link. The first protrusion 211 is connected to the adjacent belt link by a knurled pin. The front end of the first tail piece 210 (the end of the first tail piece 210 adjacent to the cover 120) includes two oppositely arranged lugs 212, and a slot 213 is formed between the two lugs 212. The rear end of the cover 120 has a second protrusion 122 that inserts into the slot 213 and is hinged to the two lugs 212. The second protrusion 122 is hinged to the two lugs 212 of the first tail piece 210 by a knurled pin.

[0020] Please combine further Figure 1-3 as well as Figure 5-10The front end of the clasp 120 has an installation notch 123 that penetrates the upper and lower surfaces of the clasp 120. The clasp 100 also includes two clasp beads 130 that are correspondingly embedded in the installation notches 123 of the two clasp beads 120 and connected to the clasp beads 120. The lower surface of the clasp beads 130 has a second groove 131 that penetrates the front and rear surfaces of the clasp beads 130. In this embodiment, one end of the clasp beads 130 is connected to the clasp 120 through a male-female connector, and the other end of the clasp beads 130 is connected to the wing plate 112 through another male-female connector. In this embodiment, the part where the originally thicker tail piece is connected to the clasp 100 is separated as the clasp beads 130. In this way, only the thickness of the clasp beads 130 needs to be thicker to meet the connection between the clasp 120 and the wing plate 112, which can reduce the thickness of the first watch strap 200, the second watch strap 300, and the clasp 120, so as to meet the requirements of the thinner watch strap design. Furthermore, the upper surface of the end of the wing plate 112 (i.e., the side of the wing plate 112 facing the buckle cover 120 when the buckle frame 110 is folded) protrudes to form a mounting tube 115 that is inserted into the second groove 131. The male and female parts pass through the mounting tube 115 and are connected to the buckle cover bead 130. In this way, the main body of the wing plate 112 is hidden in the first groove 121 on the lower surface of the buckle cover 120, and the protruding mounting tube 115 (i.e., the connecting part of the buckle 100) extends into the second groove 131 of the buckle cover bead 130 and is hinged to the buckle cover bead 130, so as to achieve full coverage and storage of the wing plate 112. In this embodiment, the shape and size of the first groove 121 and the second groove 131 need to meet the following requirements: when the wing plate 112 is fully embedded in the first groove 121 and the second groove 131, the upper surface of the wing plate 112 is in contact with the top surface of the grooves of the first groove 121 and the second groove 131 (i.e., the side of the first groove 121 and the second groove 131 facing away from the upper surface of the frame 111), and the lower surface of the wing plate 112 (i.e., the side of the wing plate 112 facing away from the cover 120 when the buckle 110 is folded) does not protrude from the opening of the grooves of the first groove 121 and the second groove 131, so as to avoid the wing plate 112 scratching the user's wrist skin. In addition, the lower front surface of the cover 120 is provided with a button avoidance hole 124 that penetrates the two opposite sides of the cover 120 and the front front surface of the cover 120. The button avoidance hole 124 communicates with the mounting notch 123. The button avoidance hole 124 is used to provide a channel for the button 113 to pass through the side of the cover 120.

[0021] Please combine Figure 2-5In one embodiment, the frame 111 has an H-shaped structure, including two first arms 1111 arranged opposite each other and a second arm 1112 located between the two first arms 1111. The two ends of the second arm 1112 are respectively fixedly connected to the middle of the two first arms 1111. In this embodiment, the first arm 1111 and the second arm 1112 are integrally formed. In other embodiments, the first arm 1111 and the second arm 1112 can also be fixedly connected by welding. The two first arms 1111 form a receiving channel 1113 on each side of the second arm 1112. The two wing plates 112 are embedded in the two receiving channels 1113 respectively, and one end of the wing plate 112 is hinged to one end of the two first arms 1111 through a connecting shaft. The other end of the wing plate 112 can rotate to move closer to or away from the second arm 1112. The button 113 is slidably engaged with the middle of the first arm 1111. In this embodiment, the outer contour shape of the wing plate 112 is adapted to the inner contour shape of the receiving channel 1113. When the end of the wing plate 112 rotates to the second arm 1112, the wing plate 112 is completely embedded in the receiving channel 1113. The thickness of the wing plate 112 (i.e., the dimension of the wing plate 112 along the thickness direction of the strap structure) is less than or equal to the dimension of the receiving channel 1113 along the thickness direction of the strap structure, so as to avoid the wing plate 112 protruding out of the receiving channel 1113 when the buckle 110 is folded, thereby avoiding the problem of scratching the user's skin. The lower surface of the wing plate 112 is provided with a protrusion 1121. Inside the receiving channel 1113, a support plate 1122 fixedly connected to the first arm 1111 is provided on each side of the protrusion 1121. In this way, the wing plate 112 can be supported and positioned by the support plate 1122. The wing plate 112 can also be limited by the cooperation of the protrusion 1121 and the two support plates 1122 to prevent the wing plate 112 from shaking.

[0022] In one embodiment, a groove 1114 is provided on the outer side of the middle part of the first arm 1111, and a mounting hole 1115 is provided on the second arm 1112. The mounting hole 1115 passes through both ends of the second arm 1112. The groove 1114 communicates with the mounting hole 1115 and two receiving channels 1113 on both sides of the mounting hole 1115. The two buttons 113 are slidably inserted into the grooves 1114 of the two first arms 1111. The inner side of the button 113 (i.e. the side of the button 113 near the mounting hole 1115) is provided with two second fastening parts 114 that are inserted into the two receiving channels 1113 at intervals. A spring 140 is provided in the mounting hole 1115, and the two ends of the spring 140 abut against the middle of the inner side of the two buttons 113 respectively. In this embodiment, the positions of the button 113 and the wing plate 112 along the length direction of the second arm 1112 (i.e., the width direction of the frame 111) are limited by the cooperation of the first and second fastening parts 114, so as to prevent the button 113 from falling off the groove of the slide 1114 and ensure the stability of the buckle 100 structure. By setting a spring 140 in the mounting hole 1115, when the buttons 113 on both sides are pressed at the same time, the spring 140 is compressed by the pressure of the button 113, and the second fastening part 114 is driven by the button 113 to leave the first fastening part, so as to unlock the wing plate 112 from the frame 111; when the button 113 is released, the button 113 is reset and rebounded under the action of the spring 140, and the second fastening part 114 is driven back to the initial position, providing conditions for the next press of the button 113.

[0023] Furthermore, a through groove 116 is provided on the wing plate 112 near the second arm 1112, penetrating the upper surface of the wing plate 112. A through hole 117 is provided on the bottom surface of the through groove 116, penetrating the lower surface of the wing plate 112. At least one first step 118 and a second step 119 are formed on the edge of the through hole 117 at the edge of the through hole 117, adjacent to one side of the button 113. The through hole 117, the first step 118, and the second step 119 together form the first fastening portion. In this embodiment, the through groove 116 is a circular groove, and the through hole 117 is a square hole. The inner diameter of the through groove 116 is larger than the width of the through hole 117, and the through hole 117 is centrally located on the bottom surface of the through groove 116. The inner side of button 113 is provided with two extension arms 1131 that are correspondingly inserted into two receiving channels 1113. The upper end of the extension arm 1131 protrudes to form a second fastening part 114. The second fastening part 114 passes through the through hole 117 and engages with the first step 118 or the second step 119. In this way, when button 113 is not pressed, the second fastening part 114 abuts against the edge of the first step 118 or the edge of the second step 119 adjacent to the button 113 to limit the button 113 and prevent the button 113 from falling out of the slide groove 1114. When button 113 is pressed, the second fastening part 114 moves towards the center of the through hole 117 under the action of button 113. The second fastening part 114 moves away from the first step 118 or the second step 119, thereby releasing the constraint on the wing plate 112 so that the wing plate 112 can be lifted from the frame 111. In this embodiment, the extension arms 1131 on the same side of the two buttons 113 are staggered, that is, the positions of the two second fastening parts 114 in the same through hole 117 are staggered along the length direction of the first arm 1111 (i.e. the length direction of the watch strap structure), so as to avoid interference when the two buttons 113 on both sides are pressed, and to ensure the smoothness of pressing the buttons 113.

[0024] It should be noted that in this embodiment, the outer side of the button 113 (i.e. the side of the button 113 facing away from the mounting hole 1115) is provided with a pressing head 1132. The dimension of the pressing head 1132 along the length direction of the first arm 1111 is greater than the dimension of the slide groove 1114 along the length direction of the first arm 1111, or / and the dimension of the pressing head 1132 along the thickness direction of the first arm 1111 is greater than the dimension of the slide groove 1114 along the thickness direction of the first arm 1111. In this way, the problem of the button 113 completely entering the slide groove 1114 due to excessive pressing force on the button 113 can be avoided. The position of the pressing head 1132 on the button 113 needs to meet the following requirements: when the pressing force on the button 113 is released, the distance from the side of the pressing head 1132 adjacent to the slide groove 1114 to the outer side of the first arm 1111 is greater than 0. Furthermore, when the button 113 is pressed and the pressing head 1132 is in contact with the outer side of the first arm 1111, the second locking part 114 completely disengages from the first step 118 or the second step 119 to ensure the reliability of unlocking and locking the wing plate 112 and the frame 111. In addition, the outer side of the pressing head 1132 (i.e., the side of the pressing head 1132 facing away from the slide groove 1114) is an arc surface to improve the user's comfort when pressing the button 113.

[0025] Example 2 This utility model also discloses a watch, which includes the aforementioned watch strap structure. The watch also includes a watch head connected to the watch strap structure. The watch head includes a watch case connected to a first and second watch strap, a movement housed within the watch case, a crown that rotates through the outer wall of the watch case and is driven by the movement, a dial housed within the watch case and located above the movement, a hand assembly disposed on the side of the dial facing away from the movement and driven by the movement, a watch crystal fixed to the main surface of the watch case, and a case back fixed to the back of the watch case and encapsulating the movement, dial, and hand assembly together with the watch case. In this embodiment, the specific structure and working principle of the watch strap structure are exactly the same as in Embodiment 1, and can be referred to the relevant description in Embodiment 1 for details, which will not be repeated here.

[0026] The watch strap structure and watch of this utility model have a clasp 120 at the end of the first end link 210 and the second end link 310, and a first groove 121 is formed on the lower surface of the clasp 120. When the clasp 100 is folded, the entire clasp frame 110 can be accommodated in the first groove 121 of the clasp 120, which realizes the thinning of the connection part between the clasp 100 and the end link of the watch strap to meet the requirements of the thin and light design of the watch strap. When the watch is worn, the clasp 100 no longer protrudes from the watch strap and supports the wrist, so that the clasp 100 and the watch strap can fit snugly against the user's wrist, thereby improving the comfort of wearing the watch.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
