[0040] 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 clasp 50. When the clasp assembly 02 is locked, the first clasp 40 and the second clasp 50 are locked together; 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 the button assembly 401 set inside the clasp shell 01.

[0041] Figure 2 and Figure 3 They are structural entity diagrams of the first clasp 40 and the second clasp 50, Figure 2 and Figure 3 The buckle housing 01 is shown in FIG. 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 shell 10 and a cover 20 welded to the shell 10 .

[0042] 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 mounting groove 103. Figure 2 , Figure 4 Figure 8 and Fig. 9 As shown, the housing 10 of the first clasp 40 may be provided with a mounting groove 103 for accommodating the button assembly 401 on one side facing the cover 20. The cover 20 is covered on the housing 10 to protect the button assembly 401. The cover 20 may be provided with a first through hole 203 for the button assembly 401 to pass through. Figure 3 As shown, the first through hole on the cover of the second clasp 50 serves as the bayonet 204 for locking with the clasp 4011 of the button assembly 401. The clasp housing 01 mentioned 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.

[0043] Figure 4 and Fig. 9 The structure diagram of a watch buckle shell 01 is shown, which includes a shell 10 and a cover 20. The shell 10 includes a shell body 101 and a first welding portion 102 disposed on the shell body 101; the cover 20 is covered on the shell 10, and the cover 20 includes a cover body 201 and a second welding portion 202 formed on the cover body 201. The first welding portion 102 and the second welding portion 202 are both plastic parts or both metal parts. The cover 20 is fixed to the shell 10 by welding the second welding portion 202 to the first welding portion 102.

[0044] In this embodiment, the housing 10 may be provided with a mounting groove 103 for accommodating the button assembly 401, and the cover body 20 is covered on the housing 10 to protect the button assembly 401. Specifically, the cover body 20 covers the housing 10, and the side of the cover body 20 that is away from the housing 10 may be an appearance surface. In order to ensure that the two clasps can be locked with each other, the appearance surface of the cover body 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 cover body 20, the main structure of the cover body 20 is made of metal material. In this way, not only the structural strength of the cover body 20 is ensured, but also the cover body 20 has good corrosion resistance to prevent the cover body 20 from rusting and affecting the aesthetics and durability of the smart wearable device.

[0045] Since the main structure of the cover 20 needs to be made of metal materials, and in order to reduce the overall weight of the smart wearable, the shell 10 of the buckle shell 01 is usually made of the same plastic material as the first strap or the second strap connected thereto. Since the materials of the two are different, the thermophysical properties (such as melting point, thermal expansion coefficient, thermal conductivity, etc.) of different materials are quite different. Therefore, if the cover 20 is directly welded to the shell 10, it is easy to produce cracks or deformation at the welding point, thereby affecting the welding strength between the cover 20 and the shell 10. Therefore, in order to form a stable connection between the cover 20 and the shell 10, the structure of the cover 20 or the shell 10 can be improved by the encapsulation process, so that the parts where the shell 10 and the cover 20 are welded to each other are made of the same material, thereby improving the welding strength between the cover 20 and the shell 10.

[0046] Specifically, the housing 10 may include a housing body 101 and a first welding portion 102, and the cover 20 may include a cover body 201 and a second welding portion 202, and the first welding portion 102 and the second welding portion 202 are made of the same material. Since the thermophysical properties of the same material are consistent, the first welding portion 102 and the second welding portion 202 can achieve uniform heat distribution and fusion during the welding process, thereby improving the uniformity and reliability of the welding of the first welding portion 102 and the second welding portion 202, ensuring that the cover 20 can still be stably fixed to the housing 10 when the smart wearable device is worn for a long time, reducing the risk of the cover 20 falling off from the housing 10.

[0047] In a possible embodiment, the first welding part 102 and the second welding part 202 are both plastic parts. When welding the first welding part 102 and the second welding part 202, ultrasonic welding can be used for welding. During the welding process, the first welding part 102 and the second welding part 202 are subjected to ultrasonic vibration, and the molecules inside them will produce friction and absorb energy and then convert it into heat energy. The first welding part 102 and the second welding part 202 melt at the contact surface and form a firm connection under the action of pressure, and achieve a welding effect without false welding and gaps, thereby ensuring the connection reliability between the cover body 20 and the shell 10.

[0048] In another possible embodiment, the first welding portion 102 and the second welding portion 202 are both metal parts, and laser welding can be used to weld the first welding portion 102 and the second welding portion 202. The laser beam of laser welding can be more accurately focused, so that the weld quality of the welding point of the first welding portion 102 and the second welding portion 202 is high, and the connection reliability between the cover body 20 and the shell 10 can also be ensured.

[0049] It can be understood that since the cover 20 is welded to the shell 10, the cover 20 and the shell 10 are heated to a molten state in the welding area and fuse with each other, and this atomic or molecular level bonding force is much stronger than the bonding force formed by the adhesive on the surface of the structural part. Therefore, the connection solution provided by the embodiment of the present application to fix the cover 20 to the shell 10 based on welding of the same material greatly reduces the risk of the cover 20 falling off from the shell 10 compared to the technical solution of directly bonding the cover to the shell in the related art.

[0050] In this way, the buckle shell 01 provided in the embodiment of the present application improves the welding strength between the first welding part 102 and the second welding part 202 of the shell 10 and the cover 20 by adjusting the first welding part 102 and the second welding part 202 to be made of the same material, so that the cover 20 can be stably fixed to the shell 10. The stable welding relationship between the shell 10 and the cover 20 is not affected by the wearing environment, temperature and other factors, thereby improving the wearing reliability of the smart wearable device.

[0051] In order to improve the structure of the cover body 20 or the shell body 10 through the encapsulation process so that the parts where the shell body 10 and the cover body 20 are welded to each other are made of the same material, the embodiment of the present application provides two possible implementation methods, and these two possible implementation methods will be specifically described below.

[0052] In a first possible embodiment, Figures 2 to 8 As shown, the cover body 201 is a metal part, the second welding portion 202 is located on the side of the cover body 201 facing the housing 10, the second welding portion 202 is integrally formed with the cover body 201, and the second welding portion 202 and the first welding portion 102 are both plastic parts.

[0053] In this embodiment, the cover body 201 is a metal part. Optionally, the cover body 201 can be made of 316L austenitic stainless steel, so that the cover body 201 not only has good structural strength, but also has good corrosion resistance.

[0054] like Figure 5 and Figure 6 As shown, the second welding portion 202 can be integrally formed on the side of the cover body 201 facing the housing 10 through a rubber encapsulation process so as to be welded with the first welding portion 102 of the housing 10. In the process of manufacturing the cover body 20, the cover body 201 can be placed in a mold according to the structural design of the cover body 20. A groove is provided in the mold. When the cover body 201 is placed in the mold, the groove can be located below the cover body 201, and then a plastic solution is injected into the groove and contacts the cover body 201. After the plastic solution is solidified, the second welding portion 202 integral with the cover body 201 is formed.

[0055] Since the cover body 201 and the second welding portion 202 are an integrally formed structure, that is, the second welding portion 202 made of plastic material is directly solidified on the surface of the cover body 201, a strong adhesion is formed between the second welding portion 202 and the cover body 201, thereby ensuring that the cover 20 has good structural strength.

[0056] In order to improve the bonding strength between the cover body 201 and the second welding portion 202, in some embodiments, such as Figure 7 As shown, a metal support 1011 extending toward one side of the housing 10 is formed on the cover body 201, and the second welding portion 202 is coated on the metal support 1011. Optionally, the metal support 1011 can be configured as a protrusion or a rib.

[0057] like Figure 7 As shown, the metal support 1011 can be constructed as ribs. During the injection molding process, the ribs extend into the grooves in the mold, thereby increasing the contact area between the cover body 201 and the plastic solution during the plastic injection molding process, so as to improve the connection stability between the cover body 201 and the second welding part 202 formed by the solidification of the injection molding solution.

[0058] Furthermore, if Figure 7 As shown, a plurality of hollow portions 1012 are formed on the metal support 1011 , and at least a portion of the second welding portion 202 is filled in the plurality of hollow portions 1012 .

[0059] A plurality of hollow portions 1012 are arranged at intervals on the metal support 1011 along the extension direction of the metal support 1011. During the injection molding process, the plastic solution can penetrate and fill the plurality of hollow portions 1012, so that the second welding portion 202 formed after solidification can be embedded in the interior of the metal support 1011, thereby further enhancing the connection stability between the second welding portion 202 and the metal support 1011, and improving the overall structural strength and durability of the cover 20. In order to further ensure the welding strength between the cover 20 and the housing 10, in some implementations, such as Figure 4 As shown, the shell body 101 is a plastic part, the first welding portion 102 is constructed as a groove formed on the side of the shell body 101 facing the cover body 20, and the second welding portion 202 extends toward the shell 10, and the second welding portion 202 is welded into the groove.

[0060] The shell body 101 is made of plastic as a whole, which can reduce the weight of the shell body 101, thereby reducing the weight of the entire buckle shell 01 and reducing the burden on users wearing smart wearable devices. The first welding part 102 is a groove constructed in the shell body 101, and the second welding part 202 is inserted into the groove constituting the first welding part 102 and welded to the groove wall of the groove.

[0061] It can be understood that configuring the first welding portion 102 as a groove can not only limit the second welding portion 202 to ensure that the positioning of the welding position is more accurate and reliable. In addition, configuring the first welding portion 102 as a groove can also increase the welding surface for welding the first welding portion 102 and the second welding portion 202, thereby making the welding more firm, so as to further improve the welding strength between the first welding portion 102 and the second welding portion 202.

[0062] In some embodiments, the shell body 101 is further formed with a mounting groove 103 for arranging the button assembly 401 , and the mounting groove 103 is arranged to avoid the first welding portion 102 .

[0063] When the buckle shell is the buckle shell of the first buckle 40, the shell body 101 is formed with a mounting groove 103 to install the button assembly 401 that may be set, so the first welding part 102 needs to avoid the mounting groove 103 to avoid interfering with the movement of the button assembly 401. At the same time, in order to ensure that the first magnetic part 402 that may be set on the first buckle 40 can be as close as possible, the first welding part 102 also needs to avoid the first magnetic part 402 to ensure that the first buckle 40 and the second buckle 50 are attracted to each other with the maximum magnetic force.

[0064] When the buckle shell is the buckle shell of the first buckle 40, the button components 401 are moved closer to or farther away from each other along the length direction of the shell 10 so that the buckle component 02 is unlocked or locked. Figure 4 As shown, along the width direction of the shell 10, the first welding portion 102 is located above and / or below the movement path of the button assembly 401 to avoid the button assembly 401, that is, the first welding portion 102 is located above and / or below the mounting groove 103 to avoid the button assembly 401, which reasonably utilizes the spatial layout of the shell 10 and makes the structure of the shell 10 more compact.

[0065] It should be noted that, in order to avoid redundancy, the internal structure of the second clasp 50 is not described in detail in the first possible embodiment of the present application. Except that the second clasp 50 does not have the button assembly 401 and the mounting groove 103, the rest of the structure of the clasp housing 01 of the second clasp 50 is the same as that of the first possible embodiment of the present application. Figure 4 The clasp housing 01 of the first clasp 40 shown is identical.

[0066] In the second embodiment, the structure of the cover 20 or the shell 10 is improved by the encapsulation process so that the parts where the shell 10 and the cover 20 are welded to each other are made of the same material. Figure 8 and Fig. 9As shown, the shell body 101 includes a receiving groove 104, the shell body 101 is a plastic part, the first welding part 102 is disposed in the receiving groove 104 and is integrally formed with the shell body 101, and the first welding part 102 and the second welding part 202 are both metal parts.

[0067] In this embodiment, if Fig. 9 As shown, the shell body 101 is made of plastic material, and the first welding part 102 is made of metal material. The entire cover 20 is made of metal material. As mentioned above, in order to ensure the structural strength and corrosion resistance of the cover 20, the cover 20 can be made of 316L austenitic stainless steel. In this way, in order to match the material of the cover 20 made of metal material, the first welding part 102 can also be made of 316L austenitic stainless steel.

[0068] In the process of manufacturing the shell body 101, the first welding part 102 that has been formed can be placed at a predetermined position in the mold according to the structural design of the shell body 101, and then the molten plastic solution is injected into the mold. During the flow and filling of the plastic solution, the plastic solution will naturally cover the outer peripheral side of the first welding part 102 and expose the surface of the first welding part 102. When the plastic solution solidifies to form the shell body 101, the first welding part 102 is naturally embedded in the shell body 101, and the area of ​​the shell body 101 that accommodates the first welding part 102 forms a receiving groove 104.

[0069] Optionally, a surface of the first welding portion 102 may be provided with a protrusion or a hole to increase the connection strength with the housing body 101 .

[0070] Since the shell body 101 and the first welding portion 102 are an integrally formed structure, that is, the shell body 101 made of plastic is coated on the surface of the first welding portion 102 and directly solidified, a strong adhesion is formed between the first welding portion 102 and the shell body 101, thereby ensuring that the shell 10 has good structural strength.

[0071] In some embodiments, the second welding portion 202 includes a through hole formed on the cover body 201. In order to ensure the welding strength between the cover body 20 and the housing 10, there can be multiple second welding portions 202 in the form of through holes. The welding position of the first welding portion 102 and the cover body 20 can be the surface of the first welding portion 102 facing the cover body 20.

[0072] In this embodiment, the second welding portion 202 in the form of a through hole formed on the cover body 201 facilitates the penetration and focusing of the laser beam to the first welding portion 102 during laser welding. The laser beam is irradiated to the first welding portion 102 through the through hole, so that the metal around the first welding portion 102 and the second welding portion 202 is melted, and a weld is formed when the metal cools and solidifies. In this way, the second welding portion 202 in the form of a through hole allows the laser beam to be accurately focused on the welding interface, improving the accuracy and efficiency of welding, thereby improving the welding quality between the cover body 20 and the first welding portion 102.

[0073] In some embodiments, Fig. 9 As shown, a mounting groove 103 for arranging the button assembly 401 is also formed on the first welding portion 102, and the mounting groove 103 is arranged to avoid the through hole.

[0074] When the clasp shell is the clasp shell of the first clasp 40, the installation groove 103 for installing the button assembly 401 is formed in the first welding part 102 made of metal material, so the second welding part 202 needs to avoid the installation groove 103 to avoid interfering with the movement of the button assembly 401. At the same time, in order to ensure that the magnetic parts that may be set in the first clasp 40 and the second clasp 50 can be as close as possible, the second welding part 202 also needs to avoid the magnetic parts in the clasp shell 01 to ensure that the first clasp 40 and the second clasp 50 can achieve maximum magnetic attraction.

[0075] When the buckle shell is the buckle shell of the first buckle 40, the button components 401 are moved closer to or farther away from each other along the length direction of the shell 10 so that the buckle component 02 is unlocked or locked. Fig. 9 As shown, along the width direction of the housing 10 , the second welding portion 202 is located above and / or below the movement path of the key assembly 401 to avoid the installation groove 103 for accommodating the key assembly 401 .

[0076] It should be noted that, in order to avoid redundancy, the second possible embodiment of the present application also does not repeat the internal structure of the second clasp 50. Except that the second clasp 50 does not have the button assembly 401 and the mounting groove 103, the rest of the structure of the clasp housing 01 of the second clasp 50 is the same as that of the second clasp 50. Fig. 9 The clasp housing 01 of the first clasp 40 shown is identical.

[0077] The embodiment of the present application also provides a clasp assembly 02, which 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 embodiment of the first aspect of the present application. It can be understood that the clasp assembly 02 using the clasp shell 01 of the above-mentioned embodiment has all the technical effects of the clasp shell 01 of the above-mentioned embodiment, which will not be repeated here.

[0078] In some embodiments, the first clasp 40 and the second clasp 50 may have the same clasp shell 01, that is, the first clasp 40 and the second clasp 50 both include a shell 10 and a cover 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.

[0079] Specifically, if Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the first clasp 40 further includes a button assembly 401, which is movably disposed in the mounting groove 103 of the housing 10 of the first clasp 40, and the cover body 20 is disposed above the button assembly 401. The button assembly 401 includes a fastener 4011 extending along the thickness direction of the clasp housing 01, and the fastener 4011 is exposed to the clasp housing 10 through the first through hole 203 on the cover body 20. The first through hole on the cover body 20 of the second clasp 50 can be used as a bayonet 204 for locking the fastener 4011. The portion of the fastener 4011 exposed from the cover body 20 of the first clasp 40 can extend into the bayonet 204 on the cover body 20 of the second clasp 50, and abut against the cover body 20 around the bayonet 204 on the cover body 20 of the second clasp 50, so that the first clasp 40 and the second clasp 50 are locked to each other.

[0080] like Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the button assembly 401 of the first clasp 40 includes two buttons 4013, and each button 4013 is formed with a buckle 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 sides of the housing 10 of the first clasp 40. The buckle 4011 has a locking position, and the distance between the two buckles 4011 is the largest when both are in the locking position, so that the buckle 4011 can be limited by the cover 20 of the second clasp 50 and cannot be moved out of the two bayonet holes 204 with a slightly smaller distance.

[0081] 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 mounting grooves 103 and approach each other, and the buckles 4011 are displaced to escape from the locked position, and the spacing between the buckles 4011 is reduced so that they can be disengaged from the bayonet 204 of the second clasp 50, 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.

[0082] 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 204 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 204, and the elastic member 4012 is compressed during the process of the fastener 4011 inserting into the bayonet 204. When the fastener 4011 is completely placed under the bayonet 204, that is, the fastener 4011 is completely inserted into the second clasp 50, the reset force of the elastic member 4012 resets 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 204, and the first clasp 40 and the second clasp 50 are locked.

[0083] Furthermore, if Figure 4 and Fig. 9 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 cover 20 of the first clasp 40 covers the first magnetic member 402 ; the two buttons 4013 of the first clasp 40 are respectively located on both sides of the first magnetic member 402 .

[0084] The second clasp 50 also includes a second magnetic component, which is disposed on the shell 10 of the second clasp 50. The cover 20 of the second clasp 50 covers the second magnetic component, and the two bayonet holes 204 of the second clasp 50 are also respectively located on both sides of the second magnetic component.

[0085] In the engaged state, the first magnetic member 402 and the second magnetic member are magnetically attracted to each other; in the unengaged state, the first magnetic member 402 and the second magnetic member are magnetically de-attracted from each other.

[0086] 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 are attracted to each other, and in the process of the first magnetic member 402 and the second magnetic member being attracted to each other, the buckle 4011 can be extended into the bayonet 204 and locked with the bayonet 204, 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, by pressing the button assembly 401, the buckle 4011 can be driven to move relative to the bayonet 204 and disengage from the locked position, and the buckle 4011 can be unlocked from the bayonet 204, while overcoming the magnetic attraction between the first magnetic member 402 and the second magnetic member, so that the first clasp 40 and the second clasp 50 are separated.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.
