[0046] The following will be combined with the drawings in the embodiments of the present application to clarify the technical solutions in the embodiments of the present application; it is clearly described that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0049] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure, it can be a mechanical connection, or an electrical connection, it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0051] like Figure 1 As shown, the smart wearable device includes a device host and a first strap and a second strap connected to the device host. The first strap and the second strap are detachably connected through a clasp assembly 02, so as to facilitate the user to wear and take off the smart wearable device. The clasp assembly 02 includes two clasps that can be locked to each other, namely a first clasp 40 and a second clasp 50. The first clasp 40 can be connected to the end of the first strap, and the second clasp 50 can be connected to the end of the second strap. When the clasp assembly 02 is locked, the first clasp 40 and the second clasp 50 are locked together, and when the clasp assembly 02 is unlocked, the first clasp 40 can be separated from the second clasp 50. Among them, the internal structural parts of the first clasp 40 and the second clasp 50 can be different, but both include a clasp shell 01, and the clasp shell 01 is used to protect the magnetic parts and / or button components arranged inside the clasp shell 01.

[0052] Figure 2 and Figure 3Both show the structural schematic diagram of the buckle housing 01, wherein Figure 2 The clasp housing 01 of the first clasp 40 is shown, Figure 3 The clasp housing 01 of the second clasp 50 is shown. Figure 2 and Figure 3 As shown, the buckle housing 01 includes a housing 10 and a first cover 20 covering the housing 10, and the first cover 20 is assembled with the housing 10 along a first direction. A first limiting portion 101 is formed on the housing 10, and a second limiting portion 201 is formed on the first cover 20, and the second limiting portion 201 is engaged with the first limiting portion 101 to limit the first cover 20 from separating from the housing 10 in the opposite direction of the first direction.

[0053] It should be noted that the internal structural parts of the first clasp 40 and the second clasp 50 may be different, but both include the clasp housing 01, except that the second clasp 50 does not need to be provided with a button assembly 401, so the housing 10 of the second clasp 50 does not have a receiving groove 403. Figure 2 and Figure 4 As shown, the housing 10 of the first clasp 40 may be provided with a receiving groove 403 for receiving the button assembly 401 on one side facing the first cover 20. The first cover 20 is covered on the housing 10 to protect the button assembly 401. The first cover 20 may be provided with a first through hole 209 for the button assembly 401 to pass through. Figure 3 As shown, the through hole on the first cover (or second cover) in the second clasp 50 serves as the bayonet 210 for locking with the fastener 4011 of the button assembly 401. The clasp housing 01 in the following embodiments can be the clasp housing of the first clasp 40 or the clasp housing of the second clasp 50 unless otherwise specified.

[0054] In this embodiment, the first cover 20 covers the shell 10. The side of the first cover 20 facing away from the shell 10 may be an appearance surface or an attachment surface of an appearance part. In order to ensure that the two clasps can be locked with each other, the appearance surface of the first cover 20 is constructed as a plane to ensure that the first clasp 40 and the second clasp 50 can fit tightly. At the same time, in order to ensure the structural strength of the first cover 20, the first cover 20 is made of metal material. Optionally, the first cover 20 can be made of 316L austenitic stainless steel, which not only ensures the structural strength of the first cover 20, but also makes the first cover 20 have good corrosion resistance to avoid rusting of the first cover 20 and affecting the aesthetics and durability of the smart wearable device.

[0055] like Figure 4 , Figure 7 , Fig.10 and Fig.14As shown, a first limiting portion 101 is formed on the side of the shell 10 facing the first cover body 20, and a second limiting portion 201 is formed on the side of the first cover body 20 facing the shell 10 (i.e., the surface opposite to the above-mentioned appearance surface). The first limiting portion 101 and the second limiting portion 201 are mutually engaged, thereby stably fixing the first cover body 20 to the shell 10.

[0056] Since the first limiting portion 101 and the second limiting portion 201 are formed on the shell 10 and the first cover 20, respectively, when the first cover 20 is assembled with the shell 10, the first cover 20 needs to be assembled on the shell 10 along the first direction to ensure that the first limiting portion 101 and the second limiting portion 201 smoothly form a snap-fit ​​relationship. The first direction can be perpendicular to the direction of the shell 10. Specifically, the first direction can be perpendicular to the bottom of the housing groove 403 of the shell 10 for accommodating the magnetic part or the button assembly 401. After the first cover 20 is assembled to the shell 10, the first direction is also perpendicular to the appearance surface of the first cover 20. The first direction is Figure 4 , Figure 7 , Fig.10 and Fig.14 The X direction in .

[0057] It can be understood that the first cover 20 is assembled to the housing 10 along the first direction, and the snap fit between the first limiting portion 101 and the second limiting portion 201 can limit the separation of the first cover 20 from the housing 10 along the first direction, and since the snap fit formed between the first limiting portion 101 and the second limiting portion 201 has good reliability, the first cover 20 is stably fixed to the housing 10. Therefore, the risk of the first cover 20 falling off from the housing 10 is completely avoided.

[0058] Optionally, in order to further ensure the connection stability between the first cover 20 and the housing 10, a plurality of second stoppers 201 may be formed on the first cover 20. Since the appearance of the first cover 20 is rectangular, the plurality of second stoppers 201 may be arranged at the four corners of the rectangle. Accordingly, a plurality of first stoppers 101 are formed at corresponding positions on the housing 10, so that the first cover 20 and the housing 10 form a snap fit at a plurality of points.

[0059] In addition, since a button assembly 401 may be disposed in the housing 10 of the first clasp 40, the first limiting portion 101 and the second limiting portion 201 need to be arranged away from the button assembly 401 to avoid interfering with the movement of the button assembly 401. At the same time, in order to ensure that the magnetic parts in the first clasp 40 and the second clasp 50 can be as close as possible, the first limiting portion 101 and the second limiting portion 201 also need to be arranged away from the magnetic parts to ensure that the maximum magnetic force attraction is achieved between the two magnetic parts.

[0060] In this way, the buckle shell 01 provided in the embodiment of the present application, by setting a first limiting portion 101 on the shell 10 and a second limiting portion 201 on the first cover body 20, and limiting the separation of the first cover body 20 from the shell 10 through the snap-fit ​​relationship formed by the first limiting portion 101 and the second limiting portion 201, so that the first cover body 20 can be stably set on the shell 10, and the connection stability of the above-mentioned mechanical structure is not affected by the wearing environment, temperature and other factors, thereby improving the reliability of the smart wearable device.

[0061] In order to ensure that the first cover 20 can be more tightly covered on the housing 10 and reduce the difficulty of assembly, in some embodiments, such as Figure 4 , Figure 6 , Figure 7 , Fig. 9 and Fig.13 In the embodiment, the first limiting portion 101 can be heat-melted, and a part of the first limiting portion 101 can be heat-melted and solidified to form a stopper 102 to limit the second limiting portion 201 from moving in the opposite direction of the first direction. (The first limiting portion 101 and the stopper 102 shown in the figure are in a solidified state after heat-melting and pressure).

[0062] The first limiting portion 101 can be made of plastic material so that it can be heat-melted during the assembly process. After heat-melting, part of the first limiting portion 101 is easily deformed under the action of pressure, so that the understood structural form can be snap-fitted with the second limiting portion 201. Specifically, after heat-melting, part of the first limiting portion 101 can form a stopper 102 under the action of pressure. The stopper 102 can extend in a second direction perpendicular to the first direction, and can stop and snap-fit ​​the second limiting portion 201 in the second direction, so that the second limiting portion 201 can move in the opposite direction of the first direction.

[0063] It can be understood that the first limiting portion 101 can be hot-melted when the first cover 20 is pre-assembled to the housing 10 or when the first cover 20 is assembled to the housing 10, that is, the initial form of the first limiting portion 101 before being engaged with the second limiting portion 201 is different from the form after the hot-melt solidifies and the second limiting portion 201 forms a snap-fit ​​match, so that when the first cover 20 is assembled to the housing 10, the first limiting portion 101 will not interfere with the second limiting portion 201 when pre-assembled along the first direction, and the second limiting portion 201 will be stopped along the second direction only after the first limiting portion 101 is hot-melted and solidified, so that the first limiting portion 101 forms a limit with the second limiting portion 201. It can be seen that the process of establishing the snap-fit ​​match between the first limiting portion 101 and the second limiting portion 201 by hot-melting the first limiting portion 101 is simpler and more efficient, and the first limiting portion 101 and the second limiting portion 201 are not easily damaged in the process of forming the snap-fit ​​match.

[0064] It is worth noting that since the first limiting portion 101 is made of plastic material and has a better flow shape after hot melting, the stop portion 102 formed by hot melting of the first limiting portion 101 can fit tightly onto the outer surface of the second limiting portion 201, thereby reducing the assembly gap between the first limiting portion 101 and the second limiting portion 201, and the snap-fit ​​between the first limiting portion 101 and the second limiting portion 201 is tighter and less likely to loosen, thereby further improving the assembly stability between the first cover body 20 and the shell body 10.

[0065] In this way, by hot-melting the first limiting portion 101, a snap-fit ​​fit between the first limiting portion 101 and the second limiting portion 201 is established, which not only reduces the assembly gap between the first limiting portion 101 and the second limiting portion 201, but also reduces the assembly difficulty between the first limiting portion 101 and the second limiting portion 201, thereby improving the assembly efficiency of the buckle shell 01.

[0066] In order to achieve deformation of the first limiting portion 101 by hot melting and to form a snap fit with the second limiting portion 201, the embodiment of the present application provides two possible implementation methods, which will be specifically described below.

[0067] In the first possible implementation, Figures 4 to 9 The technical solution shows that the first limiting portion 101 in the clasp housing 01 of the first clasp 40 and the second clasp 50 is constructed as a column, passes through the mounting hole 202 of the first cover body 20, is hot-melted, and then is pressed to form a stopper portion 102 to limit the first limiting portion 101 (the first limiting portion 101 is in a cured form). Figure 8 and Fig. 9 The locked state of the clasp assembly 02 is also shown.

[0068] Specifically, the first limiting portion 101 passes through the mounting hole 202 , and the first limiting portion 101 passes through the mounting hole 202 and is partially melted to form a stop portion 102 . The stop portion 102 extends radially along the first limiting portion 101 , and the stop portion 102 abuts against the edge of the mounting hole 202 .

[0069] In this embodiment, the first limiting portion 101 disposed on the housing 10 is configured as a column, the first limiting portion 101 extends in a direction opposite to the first direction, and the second limiting portion 201 includes a mounting hole 202 formed on the first cover 20 .

[0070] When the first cover body 20 is installed to the housing 10 along the first direction, the first limiting portion 101 passes through the installation hole 202 and is exposed on the first cover body 20. The free end of the first limiting portion 101 passing through the first cover body 20 is hot-melted by a hot-melt workpiece, and part of the first limiting portion 101 is heated at high temperature to become deformable. Then, pressure is applied to the free end of the first limiting portion 101 along the first direction. Due to the limiting effect of the first cover body 20, the hot-melted part of the first limiting portion 101 flows along the second direction under pressure, that is, flows along the radial direction of the first limiting portion 101, as shown in FIG. Figure 4 , Figure 6 , Figure 7 , Fig. 9 As shown, this part of the first limiting portion 101 forms a stopper 102 extending along the second direction after solidification. The stopper 102 is located on the side of the first cover 20 away from the housing 10, and abuts against the edge of the mounting hole 202, thereby clamping the first cover 20 to limit the first cover 20 and the housing 10 from separating or loosening in the opposite direction of the first direction.

[0071] In order to ensure the surface flatness of the first cover body 20, so as to facilitate the arrangement of other appearance parts outside the first cover body 20, in some embodiments, such as Figure 6 As shown, the second limiting portion 201 may include a recessed portion 203 that is recessed toward the housing 10, and the housing 10 includes a groove 103 that accommodates the recessed portion 203, and the recessed portion 203 is adapted to the groove 103. After the first cover 20 is covered on the housing 10 along the first direction, the recessed portion 203 can be stably pre-assembled in the groove 103 to facilitate subsequent hot melt processing.

[0072] Furthermore, the mounting hole 202 is disposed in the recess 203, and the first position-limiting portion 101 is disposed in the recess 103. After the first position-limiting portion 101 passes through the mounting hole 202, it can be completely or partially placed in the recess 203 of the second position-limiting portion 201. In this way, after a portion of the first position-limiting portion 101 is subjected to a hot-melt treatment, the stopper 102 formed by solidification can be completely accommodated in the recess 203, so as to prevent the first position-limiting portion 101 from protruding from the first cover 20 and affecting the surface flatness of the first cover 20.

[0073] It can be understood that part of the first limiting portion 101 has good fluidity after hot melting. Therefore, the stop portion 102 formed by solidifying part of the first limiting portion 101 can fit the inner surface of the recess 203, which is equivalent to the stop portion 102 located in the recess 203 and the shell 10 tightly clamping the first cover body 20 and reducing the assembly gap, thereby reducing the occurrence of loosening of the first cover body 20 relative to the shell 10.

[0074] In order to ensure that the buckle housing 01 has an aesthetically pleasing appearance, in some embodiments, such as Figure 4 , Figure 6 , Figure 7 , Fig. 9 As shown, the outside of the first cover body 20 is also covered with an appearance part to shield the second limiting portion 201 to prevent the second limiting portion 201 and the stop portion 102 with the mounting hole 202 from being exposed, thereby affecting the aesthetics of the buckle shell 01.

[0075] Specifically, the appearance member is the second cover 30, and the side of the second cover 30 away from the first cover 20 is the appearance surface. The second cover 30 is a flat plate structure. Figure 4 As shown, the second cover body 30 of the first clasp 40 may be provided with a second through hole 301 for the clasp 4011 of the button assembly 401 to pass through, as shown in FIG. Figure 5 or Figure 7 As shown, the second through hole 301 on the second cover body of the second clasp 50 can be used as a bayonet 210 that cooperates with the fastener 4011. The above-mentioned second through hole 301 is avoided in the part of the second cover body 30 corresponding to the second limiting portion 201 to ensure the shielding effect of the second cover body 30 on the second limiting portion 201 and the stop portion 102.

[0076] In order to ensure the structural strength and corrosion resistance of the second cover body 30, the second cover body 30 can also be made of 316L austenitic stainless steel to prevent the second cover body 30 from rusting and affecting the appearance and durability of the smart wearable device.

[0077] Optionally, the second cover 30 can be bonded to the side of the first cover 20 away from the housing 10 by means of adhesive 302 to simplify the process. It should be noted that although the second cover 30 is also connected by bonding, since the first cover 20 and the second cover 30 are both made of metal materials, or are made of the same metal material, the bonding force of the adhesive 302 between the first cover 20 and the second cover 30 is much greater than the bonding force of directly bonding the metal cover to the plastic housing in the related art, so the risk of the second cover 30 falling off is also greatly reduced. Specifically, the adhesive 302 can be epoxy resin adhesive.

[0078] Optionally, the second cover body 30 may also be welded to the first cover body 20 by laser welding to ensure the connection stability between the second cover body 30 and the first cover body 20 .

[0079] In the second implementation method of using hot melting to deform the first limiting portion 101 and form a snap fit with the second limiting portion 201, as shown in FIG. Figures 10 to 13As shown, the second limiting portion 201 is constructed in a columnar shape, and the second limiting portion 201 is arranged on the side of the first cover body 20 facing the shell body 10. A recessed portion 204 recessed along the second direction is formed on the circumferential surface of the second limiting portion 201. Since the second limiting portion 201 is located on the side of the first cover body 20 facing the shell body 10, the other side surface of the first cover body 20 can be directly used as the appearance surface, and the first cover body 20 can be exposed to the external environment without the need for other decorative parts to cover the first cover body 20. It should be noted that, in order to avoid redundancy, the internal structure of the second clasp 50 is not introduced in the embodiment of the present application. Except that the second clasp 50 does not have the button assembly 401 and the receiving groove 403, the rest of the structure of the clasp shell 01 of the second clasp 50 is the same as that of the first clasp 50. Figures 10 to 13 The clasp housing 01 of the first clasp 40 shown is identical.

[0080] Alternatively, if Fig.11 As shown, the columnar second limiting portion 201 can be formed on the first cover body 20 by the metal injection molding process (Metal Injection Molding, referred to as MIM), so that the second limiting portion 201 is formed on the first cover body 20 by an integral molding method, and the second limiting portion 201 has better structural strength.

[0081] Further, the second limiting portion 201 is located on the side of the first cover 20 facing the housing 10 and extends along the first direction. A recessed portion 204 recessed along the second direction is provided on the outer circumference of the second limiting portion 201. The recessed portion 204 may be a hole or a groove. Fig.12 and Fig.13 As shown, the first limiting portion 101 includes a groove body 104 formed in the housing 10, and the second limiting portion 201 can be inserted into the groove body 104 along the first direction by operating the first cover body 20. In the process of inserting the second limiting portion 201 into the groove body 104, the welding head of the ultrasonic device contacts the second limiting portion 201 to increase the temperature of the second limiting portion 201, and the high temperature is transmitted to the surrounding side of the groove body 104 through the second limiting portion 201, so that a part of the groove wall of the groove body 104 is heat-melted and flows into the recessed portion 204 after solidification, and forms the above-mentioned stopper 102 after solidification.

[0082] Specifically, the initial inner diameter of the groove body 104 of the first limiting portion 101 can be smaller than the outer diameter of the second limiting portion 201, and the groove of the groove body 104 can be provided with a guide portion with a slightly larger diameter and an inclined surface to facilitate the first limiting portion 101 to extend. During the process of the second limiting portion 201 extending into the groove body 104, the second limiting portion 201 gradually heat-melts the groove body 104 from the first direction, and the molten plastic material with fluidity flows into the recessed portion 204 of the second limiting portion 201, and forms a stopper 102 extending along the second direction after solidification. A part of the groove body 104 solidifies into the stopper 102 after hot melting, so the diameter of the groove body 104 is enlarged, and then the second limiting portion 201 can be fully inserted into the groove body 104, and forms a tight fit with the groove body 104 after the diameter is enlarged to reduce the assembly gap.

[0083] Optionally, a first guiding slope 205 is formed at the free end of the second limiting portion 201 , and the first guiding slope 205 of the second limiting portion 201 can cooperate with the guiding portion at the notch of the slot body 104 to guide the second limiting portion 201 to be inserted into the slot body 104 .

[0084] In this way, by hot-melting the first limiting portion 101 in the form of a groove body 104, the first limiting portion 101 forms a stop portion 102 that can be embedded in the second limiting portion 201 along the second direction after solidification, so as to limit the separation or loosening of the second limiting portion 201 relative to the first limiting portion 101. Even if the smart wearable is used for a long time, the first cover body 20 is still firmly fixed to the shell 10.

[0085] In order to simplify the assembly process and assembly process of the first cover body 20 and the housing 10, the embodiment of the present application also provides other implementations of stably snap-fitting the first cover body 20 to the housing 10 by directly snapping. In this implementation, Figures 14 to 17 The second limiting portion 201 is constructed as a column and extends along the first direction. The second limiting portion 201 is arranged on the side of the first cover body 20 facing the shell body 10. The free end of the second limiting portion 201 is formed with a hook portion 206. The first limiting portion 101 includes a mounting groove 105 to achieve direct clamping of the first limiting portion 101 and the second limiting portion 201. It should be noted that in order to avoid redundancy, the embodiment of the present application does not introduce the internal structure of the second clasp 50. Except that the second clasp 50 does not have a button assembly 401 and a receiving groove 403, the rest of the structure of the clasp shell 01 of the second clasp 50 is the same as that of the clasp shell 01. Figures 14 to 17 The clasp housing 01 of the first clasp 40 shown is identical.

[0086] Specifically, the hook portion 206 extends radially along the second limiting portion 201, and the hook portion 206 is also made of metal material and is integrally formed with the second limiting portion 201. Similarly, since the second limiting portion 201 is located on the side of the first cover 20 facing the housing 10, the other side surface of the first cover 20 can be directly used as the appearance surface, and the first cover 20 can be exposed to the external environment without other decorative parts to cover the first cover 20.

[0087] like Figures 14 to 17 As shown, the first limiting portion 101 includes a mounting groove 105 formed on the shell 10, and the second limiting portion 201 is inserted into the mounting groove 105 along the first direction. The inner wall of the mounting groove 105 close to the bottom of the groove is formed with a slot 106 that is engaged with the hook portion 206. When the second limiting portion 201 is fully inserted into the mounting groove 105, the hook portion 206 can extend into the slot 106 of the inner wall of the mounting groove 105, and the slot 106 limits the hook portion 206 from moving in the opposite direction of the first direction, so that the first cover body 20 is stably engaged to the shell 10.

[0088] Furthermore, the hook portion 206 includes a second guiding slope 207 , and the slot of the installation slot 105 has a third guiding slope 107 . The second guiding slope 207 cooperates with the third guiding slope 107 to guide the hook portion 206 to be inserted into the installation slot 105 .

[0089] Specifically, the thickness of the free end of the hook portion 206 is gradually reduced to form the second guiding slope 207, which is inclined in a direction away from the housing 10. When the second position-limiting portion 201 is inserted into the mounting groove 105 along the first direction, the second guiding slope 207 contacts the third guiding slope 107 at the notch of the mounting groove 105, and the sliding fit between the second guiding slope 207 and the third guiding slope 107 reduces the friction force of the second position-limiting portion 201 during the insertion into the mounting groove 105, so that the hook portion 206 can smoothly guide the second position-limiting portion 201 to be inserted into the mounting groove 105.

[0090] It can be understood that since the shell 10 can be made of plastic material, the groove wall of the installation groove 105 of the first limiting portion 101 has a certain degree of deformability. In this way, when the second limiting portion 201 made of metal material and its hook portion 206 are pressed into the installation groove 105, the deformation of the installation groove 105 can make the second limiting portion 201 more easily inserted into the installation groove 105 and form a snap-fit.

[0091] In this way, during the process of assembling the first cover body 20 to the shell body 10, pressure can be applied to the first cover body 20, so that the hook portion 206 of the second limiting portion 201 is directly pressed into the slot 106 of the first limiting portion 101. While simplifying the assembly process and improving the overall assembly efficiency of the buckle shell 01, it also ensures that the first cover body 20 is stably fixed on the shell, greatly reducing the risk of the first cover body 20 falling off.

[0092] In order to further reduce the assembly gap between the first cover 20 and the housing 10, in some embodiments, as Fig.14 and Fig.15 As shown, a positioning member 208 is also provided on the first cover 20, and the positioning member 208 is provided on the side of the first cover 20 facing the housing 10 and is located between the two second limiting portions 201. Correspondingly, a positioning groove 109 for accommodating the positioning member 208 is also formed on the housing 10, and the positioning member 208 is inserted into the positioning groove 109 along the first direction and bonded to the inner wall of the positioning groove 109.

[0093] It can be understood that a stable connection relationship can be achieved between the slot 106 of the first limiting portion 101 and the hook portion 206 of the second limiting portion 201, but due to the limitation of the processing technology, there may be a certain assembly gap between the two along the first direction, resulting in the first cover 20 may not be able to cover the shell 10 tightly. By arranging the positioning member 208 on the first cover 20 and bonding the positioning member 208 to the positioning groove 109 of the shell 10, the adhesive with fluidity can adjust the assembly gap between the first cover 20 and the shell 10, so that the first cover 20 is tightly covered on the shell 10, and the bonding force generated by the adhesive can further improve the connection stability between the first cover 20 and the shell 10.

[0094] As described above, multiple second limiting portions 201 can be located at the corners of the first cover body 20, so the positioning member 208 can be set in the middle area of ​​the first cover body 20 to make the fixing points between the first cover body 20 and the shell 10 more dispersed, so that a more stable connection is formed between the first cover body 20 and the shell 10.

[0095] Furthermore, if Fig.15 As shown, the positioning member 208 may be provided with a plurality of hollow holes 208a, and the fluid adhesive may be filled in the hollow holes 208a to increase the bonding area between the positioning member 208 and the positioning groove 109. Meanwhile, the fluid adhesive may flow to the hollow holes 208a and solidify in the hollow holes 208a during the process of inserting the positioning member 208 into the positioning groove 109, so as to prevent the adhesive from flowing out of the positioning hole.

[0096] In any of the above embodiments, the first cover body 20 and the second limiting portion 201 can be an integral structure, and the second limiting portion 201 and the first cover body 20 can be made of metal material, thereby ensuring the connection strength between the first cover body 20 and the second limiting member and improving the overall durability of the buckle shell 01.

[0097] The present application embodiment also provides a buckle assembly 02, such as Figure 1 , Figure 8 , Fig. 9 and Fig.18 As shown, the clasp assembly 02 includes a first clasp 40 and a second clasp 50. The first clasp 40 and / or the second clasp 50 include the clasp shell 01 provided in the first aspect embodiment of the present application. It can be understood that the clasp assembly 02 using the clasp shell 01 of the above embodiment has all the technical effects of the clasp shell 01 of the above embodiment, which will not be repeated here.

[0098] As mentioned above, the first clasp 40 and the second clasp 50 can have the same clasp shell 01, that is, the first clasp 40 and the second clasp 50 both include a shell 10 and a first cover body 20 covered on the shell 10, but the structural parts arranged in the shell 10 of the first clasp 40 and the second clasp 50 are different.

[0099] Specifically, if Figure 2 , Figure 4 , Figure 7 , Fig.10 and Fig.14 As shown, the first clasp 40 includes a button assembly 401, which is disposed in a receiving groove 403 of the housing 10 of the first clasp 40, and the first cover 20 is covered on the button assembly 401. The button assembly 401 includes a fastener 4011 extending in the opposite direction of the first direction, and a first through hole 209 (or a second through hole 301) is formed on the first cover 20 (or the second cover 30) of the first clasp 40. When the first cover 20 of the first clasp 40 is assembled to the housing 10 along the first direction, the fastener 4011 is exposed to the clasp housing 10 through the first through hole 209 (or the second through hole 301) on the first cover 20 (or the second cover 30). The second clasp 50 includes a bayonet 210 for locking the fastener 4011. The bayonet 210 can be formed on the first cover 20 (or the second cover 30) of the second clasp 50. The bayonet 210 is actually a first through hole 209 (or second through hole 301) formed on the first cover 20 (or the second cover 30). The portion of the fastener 4011 exposed outside the first cover 20 (or the second cover 30) of the first clasp 40 can extend into the bayonet 210 on the first cover 20 (or the second cover 30) of the second clasp 50 and form a snap connection with the bayonet 210, so that the first clasp 40 and the second clasp 50 are locked with each other.

[0100] like Figure 2 , Figure 4 , Figure 7 , Fig.10 and Fig.14 As shown, the button assembly 401 of the first clasp 40 includes two buttons 4013, each of which is formed with a clasp 4011. In addition, each button 4013 is provided with an elastic member 4012 to provide a reset force to the button 4013, and the two buttons 4013 are respectively exposed on the side of the housing 10. Fig.18 As shown, the fastener 4011 has a locking position, and the distance between the two fasteners 4011 is the largest when both are in the locking position, so that the fastener 4011 can be limited by the first cover body 20 of the second clasp 50 and cannot be moved out of the two relatively small slots 210.

[0101] When the first clasp 40 and the second clasp 50 are locked with each other, the user squeezes the two buttons 4013 at the same time, so that the two buttons 4013 can move toward the inside of the housing 10 in their respective receiving grooves 403 and approach each other, and the buckle 4011 is displaced to escape from the locked position, and the spacing between the buckles 4011 is reduced so that they can be released from the bayonet 210, and the first clasp 40 is separated from the second clasp 50, and the elastic member 4012 is compressed. After the first clasp 40 is separated from the second clasp 50, the resetting force of the elastic member 4012 restores the buckle 4011 to the locked position.

[0102] When the first clasp 40 and the second clasp 50 need to be locked again, the first clasp 40 can be pressed toward the second clasp 50, and the bayonet 210 pushes the fastener 4011 to move so that the two fasteners 4011 are close to each other to leave the locked position, so that the distance between the fasteners 4011 becomes smaller so that they can be inserted into the bayonet 210, and the elastic member 4012 is compressed during the process of the fastener 4011 inserting into the bayonet 210. When the fastener 4011 is completely placed under the bayonet 210, that is, the fastener 4011 is completely inserted into the second clasp 50, the reset force of the elastic member 4012 moves the button 4013 to the locked position, and the distance between the two fasteners 4011 increases so that they cannot be removed from the bayonet 210, and the first clasp 40 and the second clasp 50 are locked.

[0103] Furthermore, if Figure 2 , Figure 4 , Figure 7 , Fig.10 and Fig.14 As shown, the first clasp 40 also includes a first magnetic member 402, which is disposed on the shell 10 of the first clasp 40, and the first cover body 20 of the first clasp 40 covers the first magnetic member 402, and the two buttons of the first clasp 40 are respectively located on both sides of the first magnetic member 402.

[0104] like Figure 7 As shown, the second clasp 50 also includes a second magnetic component 501, which is disposed on the shell 10 of the second clasp 50, the first cover body 20 of the second clasp 50 covers the second magnetic component 501, and the two bayonet holes 210 of the second clasp 50 are also respectively located on both sides of the second magnetic component 501.

[0105] In the engaged state, the first magnetic member 402 and the second magnetic member 501 are magnetically attracted to each other, and in the unengaged state, the first magnetic member 402 and the second magnetic member 501 are magnetically de-attracted from each other.

[0106] When the user wears the smart wearable device, the first clasp 40 and the second clasp 50 can be gradually brought closer, so that the first magnetic member 402 and the second magnetic member 501 are attracted to each other, and in the process of the first magnetic member 402 and the second magnetic member 501 being attracted to each other, the buckle 4011 is extended into the bayonet 210 and locked with the bayonet 210, so that the first clasp 40 and the second clasp 50 are magnetically attracted and locked. When the user needs to take off the smart wearable device, pressing the button assembly 401 can drive the buckle 4011 to move relative to the bayonet 210 and disengage from the locked position, thereby unlocking the buckle 4011 from the bayonet 210, and at the same time overcoming the magnetic attraction between the first magnetic member 402 and the second magnetic member 501, so that the first clasp 40 is separated from the second clasp 50.

[0107] Thus, the buckle assembly 02 provided in this embodiment has a simple structure and is easy for the user to wear. At the same time, when the smart wearable device is accidentally bumped, pulled or shaken, the first buckle 40 and the second buckle 50 of the buckle assembly 02 will not be separated, thereby improving the locking ability of the buckle assembly 02 and further improving the wearing reliability of the smart wearable device.

[0108] An embodiment of the present application also provides a smart wearable device, which includes the buckle assembly 02 in any of the above embodiments and a device body, a first strap and a second strap, wherein one end of the first strap is connected to the first end of the device body, the other end of the first strap is connected to the first buckle 40 of the buckle assembly 02, one end of the second strap is connected to the second end of the device body, and the other end of the second strap is connected to the second buckle 50 of the buckle assembly 02.

[0109] The first strap and the second strap are connected to the device host, respectively. When the smart wearable device is accidentally bumped, pulled or shaken, the first clasp 40 and the second clasp 50 connected to the first strap and the second strap, respectively, will not be detached, and the device host is stably bound to the user's wrist through the first strap and the second strap, thereby improving the user's experience of wearing the smart wearable device.

[0110] It can be understood that the smart wearable device adopting the buckle assembly 02 of the above embodiment has all the technical effects of the buckle assembly 02 of the above embodiment, which will not be repeated here.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
