[0001] This utility model relates to the field of wearable devices, specifically to a press-type quick-release watch strap structure and a watch. Background Technology

[0002] Most quick-disassembly watch mechanisms on the market today use sliding grooves and magnetic attachments for fixation. When replacing, the magnetic structure is separated by pressing, and then the watch is removed from the sliding groove. However, due to aesthetic reasons, the sliding groove cannot be made too large, resulting in the related structure being too small. During disassembly, it is often necessary to use a fingernail to pry open the relevant buttons. In addition, whether it is a traditional watch or a smartwatch, the space on the back of the watch is not large. Therefore, a structure that is both aesthetically pleasing and easier to operate than the traditional structure is needed.

[0003] Therefore, it is necessary to provide a push-button quick-release strap structure and watch to solve the above problems. Utility Model Content

[0016] Please see Figures 1-7 The push-to-release watch strap structure of this utility model includes a watch case assembly 1, a back cover 2, a watch strap insert 3, and a buckle assembly 4, and the end of the watch strap insert 3 has a watch strap connecting part 34 for connecting the watch strap.

[0017] The watch case assembly 1 includes a housing and a movement housed inside the housing. The housing and the bottom cover 2 form a sealed space, in which the movement house is installed. The strap insert 3 is connected to the connection between the housing and the bottom cover 2 of the watch case assembly 1, and the watch strap is connected to the strap connecting part 34 of the strap insert 3. A first groove 12 and a connecting screw hole 11 are provided on the side of the housing connected to the bottom cover 2 (i.e., the lower surface of the housing). Specifically, the first groove 12 can be located at the 6 o'clock or 12 o'clock position on the housing, and a first notch is provided on the vertical side near the first groove 12, which connects to the first groove 12. Specifically, the first notch is a half-hole, meaning that the dimension of the first notch in the direction perpendicular to the lower surface of the housing is smaller than the dimension of the first groove 12 in the direction perpendicular to the lower surface of the housing. The connecting screw holes 11 are located at the four corners of the lower surface of the housing, and the bottom cover 2 can be fixed to the housing by fasteners that are locked to the connecting screw holes 11.

[0018] The upper surface of the bottom cover 2 has a second groove 22 and a second notch, wherein the position, shape and size of the second groove 22 correspond to the position, shape and size of the first groove 12, and the position, shape and size of the second notch correspond to the position, shape and size of the first notch, and the second notch is connected to the second groove 22. A through hole 25 is provided in the middle of the second groove 22, and the through hole 25 is connected to the second notch, thereby forming a U-shaped opening at the edge of the bottom cover 2.

[0019] The upper surface of the bottom cover 2 is assembled onto the lower surface of the case assembly 1. The first groove 12 and the second groove 22 are combined to form a mounting cavity. The first notch and the second notch are combined to form a plug-in interface, and the plug-in interface is connected to the mounting cavity. The latch assembly 4 is installed in the mounting cavity. The latch assembly 4 is provided with a pressing part 41, which is embedded into the through hole 25.

[0020] In practical applications, the mounting cavity and the connector can also be set separately on the case 1 or the bottom cover 2. For example, two sets of connectors can be set on the sides of the case 1 at the 6 o'clock and 12 o'clock positions (the sides perpendicular to the lower surface of the case 1), and the connectors can be connected to the mounting cavity. Similarly, two sets of connectors can be set on the sides of the bottom cover 2 at the 6 o'clock and 12 o'clock positions (the sides perpendicular to the upper surface of the bottom cover 2), and the connectors can be connected to the mounting cavity.

[0021] In one embodiment of this utility model, the watch strap insert 3 is provided with a connecting lug 32, and the locking assembly 4 is provided with an elastic element 5 on the side facing away from the pressing part 41. The other end of the elastic element 5 is fixedly connected to the lower surface of the first groove 12 of the watch case assembly 1. The locking assembly 4 presses the connecting lug 32 to the upper surface of the second groove 22 by the elastic force of the elastic element 5. The locking edge protrusion 42 of the locking assembly 4 passes through the first fixing hole 33 provided in the middle of the connecting lug 32, and the watch strap insert 3 is fastened and installed by the locking assembly 4.

[0022] The elastic element 5 is located between the locking assembly 4 and the bottom wall of the first groove 12, and there is a gap between the main body of the locking assembly 4 and the bottom wall of the second groove 22 when no external force is applied (when the pressing part 41 of the locking assembly 4 is not pressed). When the watch strap is installed on the watch case, the connecting lug 32 on the strap insert 3 is first inserted into the locking assembly 4, that is, the connecting lug 32 is inserted through the insertion interface into the gap between the main body of the locking assembly 4 and the bottom wall of the second groove 22. At the same time, the locking edge protrusion 42 of the locking assembly 4 is pushed to move in a direction perpendicular to the bottom wall of the second groove 22. The elastic element 5 is compressed until the first fixing hole 33 of the connecting lug 32 reaches below the locking edge protrusion 42 of the locking assembly 4. The elastic element 5 pushes the locking assembly 4, so that the locking edge protrusion 42 is embedded into the first fixing hole 33 of the connecting lug 32, thereby preventing the strap insert 3 from coming out.

[0023] When removing the watch strap, press the pressing part 41, the locking assembly 4 compresses the elastic element 5, which widens the gap between the locking assembly 4 and the bottom wall of the second groove 22, and the locking protrusion 42 exits from the first fixing hole 33, so that the connecting ear 32 can be pulled out of the interface. Release the pressing part 41, and the elastic element 5 pushes the locking assembly 4 to reset.

[0024] Reference Figure 1 and Figure 2 The case assembly 1 and the back cover 2 are fixedly connected. The strap insert 3 is installed by insertion and removal through the first notch and the second notch of the case assembly 1 and the back cover 2. The pressing part 41 is used to control the installation and removal of the strap insert 3.

[0025] Reference Figure 3 The locking assembly 4 includes a base 40 and a pressing part 41, which are connected in a "T" shape. Two locking protrusions 42 are provided on the surface of the base 40 connected to the pressing part 41, with the two locking protrusions 42 located on opposite sides of the pressing part 41. A countersunk hole 44 is provided on the surface of the base 40 facing away from the pressing part 41, and an elastic element 5 is installed in the countersunk hole 44. The strap insert 3 includes an insert platform 31, with two connecting lugs 32 fixed to the same side of the insert platform 31. A clearance notch corresponding to the pressing part 41 of the locking assembly 4 is formed between the two connecting lugs 32, and a first fixing hole 33 is provided in the center of each connecting lug 32. When the connecting lug 32 and the locking assembly 4 are locked, the locking protrusion 42 is inserted into the first fixing hole 33.

[0026] refer to Figure 5 The connecting ear 32 has a first wedge surface 35 at the insertion end. When it is inserted into the first notch and the second notch, the insertion end of the connecting ear 32 extends into the gap between the second groove 22 and the locking protrusion 42. The first wedge surface 35 pushes the base 40 of the locking assembly 4 to compress the elastic member 5, thereby fully inserting the connecting ear 32 into the mounting cavity.

[0027] Similarly, the locking protrusion 42 has a second wedge surface on the side facing the insertion interface. When the connecting ear 32 extends into the mounting cavity and contacts the locking protrusion 42, it slides along the second wedge surface of the locking protrusion 42, thereby pushing the locking protrusion 42 and the base 40 to move in a direction perpendicular to the bottom wall of the second groove 22 until the locking protrusion 42 extends into the first fixing hole 33 on the connecting ear 32.

[0028] In practical applications, the first wedge surface 35 and the second wedge surface can exist independently (only the first wedge surface 35 or the second wedge surface is provided), or they can exist simultaneously (both the first wedge surface 35 is provided on the connecting ear 32 and the second wedge surface is provided on the locking protrusion 42). When both exist simultaneously, refer to... Figure 6 The second wedge surface of the locking protrusion 42 has the same slope as the first wedge surface 35. When the connecting ear 32 is inserted, the base 40 of the locking assembly 4 can move smoothly along the direction perpendicular to the bottom wall of the second groove 22 through the cooperation of the first wedge surface 35 and the second wedge surface. When the locking protrusion 42 is inserted into the first fixing hole 33 of the connecting ear 32, the rear side of the second wedge surface of the locking protrusion 42 is in contact with the inner side of the first fixing hole 33, which strengthens the locking effect.

[0029] As a preferred embodiment, refer to Figure 3 The base 40 is connected to the pressing part 41, where there is a limit step 43, for reference. Figure 4 Correspondingly, on the bottom cover 2, a mounting step 24 is provided on the lower surface of the bottom cover 2 adjacent to the through hole 25, and a bottom groove 26 is provided in the middle of the bottom cover 2; the limiting step 43 and the mounting step 24 cooperate with each other to achieve the blocking effect when the strap insert 3 and the clasp assembly 4 are connected, and to prevent the pressing part 41 from being fully inserted into the through hole 25 and stuck at the edge of the second groove 22 when the elastic element 5 experiences elastic fatigue, thus preventing it from being unable to reset. Because a gap is required between the second groove 22 and the base 40 for the connecting lug 32 to be inserted and installed, a gap exists between the bottom groove 26 and the through hole 25 to ensure the sealing of the watch movement. Figure 5 When the bottom groove 26 and the cover 27 are closed, the movement is in the bottom groove 26 and is not connected to the through hole 25.

[0030] refer to Figure 3 and Figure 7 The bottom cover 2 has stop heads 21 on both sides of the second groove 22 that hold the base 40 against it, so that the locking protrusion 42 on the base 40 cannot be completely pressed against the bottom wall of the second groove 22. This prevents the locking protrusion 42 and the second groove 22 from being unable to be inserted due to the excessive elastic force of the elastic element 5, resulting in too small a gap between the bottom walls of the locking protrusion 42 and the second groove 22. At the same time, the fastener 6 passes through the second fixing hole 23 and is fixedly connected to the connecting screw hole 11, thus securing the watch case assembly 1 and the bottom cover 2.

[0031] refer to Figure 4The strap connector 34 at the end of the strap insert 3 is used to install the strap, and the concave groove 341 can install the strap beads. The through hole tube 36 therein can be connected to the strap beads by inserting a pin.

[0032] In summary, as a preferred embodiment, during the installation of the watch strap, the watch strap is first fixedly connected through the concave groove 341 and through hole tube 36 on the watch strap connecting part 34. Then, the connecting ear 32 of the watch strap insert 3 is inserted through the insertion interface between the watch case assembly 1 and the bottom cover 2. The insertion interface and the mounting cavity formed by the first groove 12 and the second groove 22 are connected. After the connecting ear 32 enters the mounting cavity, the first wedge surface 35 of the connecting ear 32 enters the gap between the locking protrusion 42 and the second groove 22 of the base 40, and lifts the base 40 until the locking protrusion 42 enters the first fixing hole 33 of the connecting ear 32. At this time, the elastic member 5 pushes the locking protrusion 42 into the first fixing hole 33, completing the locking and fixing of the connecting ear 32, thereby completing the installation of the watch strap insert 3. When removing the watch strap, press the pressing part 41 to push the elastic element 5 to compress the base 40 until the locking protrusion 42 is fully extended from the first fixing hole 33. At this time, pull the connecting ear 32 out of the plug interface, then release the pressing part 41, the elastic element 5 resets, and pushes the locking assembly 4 to reset.

[0033] This utility model also provides a watch, including the push-to-release watch strap structure as described above.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
