[0030] As used herein, "smart watch" refers to a watch with information processing capabilities that meets the basic technical requirements of a watch. In addition to indicating time, the watch should also have one or more functions such as reminder, navigation, calibration, monitoring, and interaction. For example, the watch can comply with the data transmission standard of Bluetooth 4.0 to achieve collaborative interaction capabilities. It can also be equipped with a variety of monitoring sensors, such as sensors for monitoring ambient light, geomagnetism, temperature, air pressure, altitude, gyroscope, accelerometer, and heart rate. In addition, the display mode of the watch can include hands, numbers, and images, etc.

[0031] After long-term research by the applicant, it is found that although the smart watches in some technical solutions can achieve detachable connection between the watch band and the watch head, the connection structure between the watch band and the watch head in this solution is unreliable and has low bonding strength in the horizontal direction (i.e., the length direction of the watch band). At the same time, since the watch band is easily subjected to a large horizontal pulling force, the watch band and the watch head in the above solution often cannot meet the test requirement of withstanding a 100N horizontal pulling force of the watch band, and the problem of loosening between the watch band and the watch head is likely to occur during actual use, resulting in a reduction in the reliability of the smart watch. To solve the above problems, the embodiments of the present application provide a detachable structure, a wearable device, a watch band and a watch head. The present application will be further described in detail below with reference to the drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0032] The mention of "embodiment" in the present application means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0033] Please refer to Figures 1 to 2 , Figure 1 which is a schematic structural diagram of the wearable device 10 provided by the embodiment of the present application, Figure 2 is Figure 1 the exploded structural diagram of the wearable device 10 in

[0034] As Figure 1 shown, the wearable device 10 provided by the embodiment of the present application may be a smart watch, which can be worn on the user's wrist. In addition to providing conventional services such as calendars and time for the user, it can also provide services such as payment, identity verification, voice calls, and video chats for the user, and can also monitor data indicators such as the user's daily exercise situation and physical health status. As Figure 2As shown, the wearable device 10 may include: a watch band 100 and a watch head 200. Among them, a connecting member 120 may be provided on the watch band 100, and a mating member 220 and a pushing member 230 may be provided on the watch head 200. The connecting member 120 may be inserted into the mating member 220 from the thickness direction X of the watch band 100 and be snap-connected to the mating member 220. The pushing member 230 may be used to push the connecting member 120 to displace, so as to release the snap connection state between the connecting member 120 and the mating member 220. Thus, the watch band 100 and the watch head 200 can be detachably connected through the cooperation of the connecting member 120, the mating member 220 and the pushing member 230, and the whole disassembly and assembly process is simple and convenient. At the same time, after the watch band 100 and the watch head 200 are assembled, they also have the advantage of high lateral tensile strength, ensuring the assembly reliability of the watch band 100 and the watch head 200. It should be noted that the above-mentioned lateral tension may be the tension received by the watch band 100 in its length direction or width direction. In addition, the connecting member 120, the mating member 220 and the pushing member 230 may constitute a detachable structure 300 of the wearable device 10, but the detachable structure 300 is not limited to only including the connecting member 120, the mating member 220 and the pushing member 230.

[0035] Please refer to Figures 3 to 6 , Figure 3 is Figure 2 a partial structural schematic diagram of the watch band 100 in Figure 4 is Figure 3 a structural schematic diagram of the watch band body 110 in Figure 5 is Figure 3 a structural schematic diagram of the connecting member 120 in Figure 6 is Figure 5 a cross-sectional structural schematic diagram of the connecting member 120 along V-V in

[0036] The watch band 100 is connected to the watch head 200 and is used to bind the watch head 200 to the user's wrist to realize the wearing of the wearable device 10. For example, the number of the watch bands 100 may be two, and the two watch bands 100 are respectively connected to the opposite sides of the watch head 200. At the same time, a plurality of positioning holes may be provided on one watch band 100 in its length direction, and a positioning post may be provided on the other watch band 100. The two watch bands 100 can be fixedly connected by inserting the positioning post into the positioning hole, so that the user can bind the watch head 200 to the wrist through the watch band 100. Further, the watch band 100 can also be detachably connected to the watch head 200 to facilitate the user to replace the watch band 100 or the watch head 200. As Figure 3As shown in the figure, the watch band 100 may include: a watch band body 110 and a connecting member 120. Among them, the watch band body 110 may be provided with the above-mentioned positioning holes or positioning posts to achieve the wearing of the wearable device 10. The connecting member 120 may be disposed at the end of the watch band body 110 and used for snap connection with the mating member 220 of the watch head 200 to achieve the assembly of the watch band body 110 and the watch head 200. In this embodiment, the watch band body 110 may be made of a flexible and skin-friendly material to improve the comfort of the user when wearing. The connecting member 120 may be made of a rigid material to improve the structural strength of the connecting member 120 and the reliability of the assembly of the watch band body 110 and the watch head 200. In addition, the watch band body 110 and the connecting member 120 may also be integrally formed to improve the bonding strength between the watch band body 110 and the connecting member 120.

[0037] The end of the watch band body 110 can be used to install the connecting member 120 to facilitate the connection between the connecting member 120 and the watch head 200. As Figure 4 shown, the end of the watch band body 110 is provided with a receiving cavity 1101 for installing the connecting member 120, and the receiving cavity 1101 can penetrate one side of the watch band body 110 in the thickness direction of the watch band body 110, so that the connecting member 120 in the receiving cavity 1101 can be inserted into the mating member 220 of the watch head 200 from the thickness direction X of the watch band body 110 to achieve the assembly of the watch band 200. In this embodiment, the watch band body 110 may be made of a flexible and skin-friendly material such as silicone, fluororubber, leather, fabric and their composite materials, so that the watch band body 110 can have excellent flexibility and touch, and improve the comfort of the user when wearing the wearable device 10. In addition, a functional material for wear resistance, corrosion resistance and scratch prevention, or a functional material for sweat absorption and sweat prevention may be coated on the outer surface of the watch band body 110 to further improve the comfort of the user when wearing.

[0038] The connecting member 120 may be disposed in the receiving cavity 1101 and used for snap connection with the mating member 220 of the watch head 200 to achieve the assembly of the watch band body 110 and the watch head 200. As Figure 5As shown, the connecting member 120 may include: a main body portion 121, a plugging portion 122, and a clamping portion 123. Among them, the main body portion 121 may be disposed at an end of the watch band body 110. The plugging portion 122 and the clamping portion 123 may be disposed on the same side of the main body portion 121. The plugging portion 122 is configured to be inserted into the mating member 220 in the thickness direction X of the watch band body 110 to achieve the plugging of the connecting member 120 and the mating member 220. The clamping portion 123 is configured to be clamped with the mating member 220 in the thickness direction X after the plugging portion 122 is inserted into the mating member 220. With such a setting, after the plugging portion 122 is inserted into the mating member 220 from the thickness direction X, by clamping the clamping portion 123 with the mating member 220 in the thickness direction X, the plugging portion 122 can be prevented from coming out of the mating member 220, and the clamping of the connecting member 120 and the mating member 220 can be achieved. The watch band body 110 can utilize the clamping of the connecting member 120 and the mating member 220 to achieve the assembly of the watch band 100 and the watch head 200. In this embodiment, the material of the connecting member 120 may be a plastic with a relatively high hardness, and the main body portion 121, the plugging portion 122, and the clamping portion 123 may be integrally formed by an injection molding process to improve the structural strength of the connecting member 120. In some embodiments, the main body portion 121 may also be a component independently disposed on the watch band body 110, that is, the connecting member 120 may only include the plugging portion 122 and the clamping portion 123, and the plugging portion 122 and the clamping portion 123 may be fixedly connected to the main body portion 121 by means of bonding, welding, and bolting.

[0039] Specifically, the main body portion 121 may be disposed in the receiving cavity 1101 of the watch band body 110, and the main body portion 121 may further be provided with a receiving groove 1211, and the plugging portion 122 and the clamping portion 123 may be disposed in the receiving groove 1211. Among them, the receiving groove 1211 is configured to receive the mating member 220 after the plugging portion 122 is inserted into the mating member 220. As Figures 5 to 6As shown, the receiving groove 1211 can communicate with the opening of the receiving cavity 1101 of the watch band body 110, and the plugging portion 122 can be disposed on the bottom wall of the receiving groove 1211 perpendicular to the thickness direction X. With such a setting, the plugging portion 122 can be inserted into the fitting member 220 from the thickness direction X to achieve the plugging of the connecting member 120 and the fitting member 220. And after the plugging portion 122 is inserted into the fitting member 220, the fitting member 220 can also be received by the receiving groove 1211 to reduce the stacking space occupied by the connecting member 120 and the fitting member 220 in the thickness direction X after plugging, and improve the consistency after the plugging of the connecting member 120 and the fitting member 220. Correspondingly, the shape of the receiving groove 1211 can also be adapted to the shape of the fitting member 220 to further improve the consistency after the clamping of the connecting member 120 and the fitting member 220. In addition, a through groove 1212 communicating with the receiving groove 1211 is formed in the main body portion 121 in the thickness direction X, and the clamping portion 123 can extend into the through groove 1212 and be connected to the side wall of the through groove 1212, so as to realize the connection between the clamping portion 123 and the main body portion 121.

[0040] The plugging portion 122 can be disposed in the receiving groove 1211, and the plugging portion 122 is configured to be insertable into the fitting member 220 from the thickness direction X and engage with the fitting member 220. As Figures 5 to 6 shown, the plugging portion 122 can be obliquely disposed on the bottom wall of the receiving groove 1211 perpendicular to the thickness direction X, so that the plugging portion 122 can have an inclined surface, thereby increasing the contact area between the plugging portion 122 and the fitting member 220 to improve the firmness after the plugging portion 122 is engaged with the fitting member 220. At the same time, since the watch band 100 is often subjected to a pulling force away from the watch head 200 during actual use, the plugging portion 122 can be obliquely disposed toward the end of the watch band body 110 away from the watch head 200. In addition to increasing the contact area between the plugging portion 122 and the fitting member 220, the inclined engagement between the plugging portion 122 and the fitting member 220 can also be used to improve the tensile strength of the watch band 100 in the direction away from the watch head 200 and ensure the assembly reliability of the watch band 100 and the watch head 200. In this embodiment, two plugging portions 122 can be simultaneously provided on the connecting member 120, and the two plugging portions 122 can be respectively located on opposite sides of the through groove 1212 to further improve the firmness of the connection between the connecting member 120 and the fitting member 220. In addition, in some embodiments, in addition to being obliquely disposed, the plugging portion 122 can also be perpendicularly disposed on the bottom wall of the receiving groove 1211, as long as the plugging portion 122 can be inserted into the fitting member 220 from the thickness direction X to achieve the plugging of the connecting member 120 and the fitting member 220.

[0041] The clamping portion 123 can be arranged in the accommodation groove 1211, and the clamping portion 123 is configured to be clamped with the mating member 220 in the thickness direction X after the insertion portion 122 is inserted into the mating member 220, so as to limit the movement of the insertion portion 122 in the thickness direction X and realize the assembly of the connecting member 120 and the mating member 220. As Figures 5 to 6 shown, the clamping member 123 can extend into the through groove 1212 to be connected with the side wall of the through groove 1212, and the clamping portion 123 can be located between the two insertion portions 122. With such an arrangement, when the insertion portion 122 is inserted into the mating member 220 in the thickness direction X, the clamping portion 123 can also move in the direction close to the mating member 220 as the insertion portion 122 is inserted, so as to be clamped with the mating member 220 in the thickness direction X and prevent the insertion portion 122 from disengaging from the mating member 220.

[0042] Specifically, in order to realize the clamping of the clamping portion 123 and the mating member 220 in the thickness direction X, the clamping portion 123 is further configured to be displaced relative to the main body portion 121 during the process of the insertion portion 122 being inserted into the mating member 220, and can be clamped with the mating member 220 in the thickness direction X after resetting. For example, the mating member 220 can be located on the movement path of the clamping portion 123 in the thickness direction X, and the clamping portion 123 can have the ability of elastic deformation. When the insertion portion 122 is inserted into the mating member 220, the clamping portion 123 can abut against the mating member 220 and can be deformed under the pushing of the mating member 220, so that the clamping portion 123 is displaced relative to the main body portion 121 and prevent the abutment of the clamping portion 123 and the mating member 220 from affecting the normal insertion of the insertion portion 122. After the insertion portion 122 is inserted into the predetermined position of the mating member 220, the clamping portion 123 can be reset by its own deformation force and be clamped with the mating member 220 in the thickness direction X, so as to limit the movement of the insertion portion 122 in the thickness direction X and prevent the insertion portion 122 from disengaging from the mating member 220.

[0043] In this embodiment, since the material of the connecting member 120 is plastic, the clamping portion 123 can undergo plastic deformation to be displaced relative to the main body portion 121 and reset. In some embodiments, the material of the connecting member 120 can also be a metal with deformation ability, so that while the connecting member 120 has a certain structural strength, the clamping portion 123 can still be deformed to be displaced relative to the main body portion 121 and reset, so as to realize the clamping of the clamping portion 123 and the mating member 220 in the thickness direction. It should be noted that the above-mentioned predetermined position can refer to the position where the insertion portion 122 is completely immersed in the mating member 220, so as to reduce the stacking space occupied by the insertion portion 122 and the mating member 220 in the thickness direction X. Of course, the predetermined position can also be specifically set according to actual needs, and this embodiment does not limit this.

[0044] Further, in order to enable the engaging portion 123 to deform under the pushing of the mating member 220 and generate a displacement relative to the main body portion 121, the engaging portion 123 may further be provided with a first surface 1231, and the first surface 1231 may be an inclined surface. When the inserting portion 122 is inserted into the mating member 220, the first surface 1231 can be used to abut against the mating member 220 to generate an abutting force to push the engaging portion 123 to deform, so that the engaging portion 123 generates a displacement relative to the main body portion 121. After the inserting portion 122 is inserted into the predetermined position of the mating member 220, the first surface 1231 can be separated from the mating member 220, so that the engaging portion 123 can be reset by its own deformation force, thereby being engaged with the mating member 220 in the thickness direction X. In this embodiment, in addition to being an inclined surface, the first surface 1231 may also be an arc surface, as long as the mating member 220 can generate an abutting force to push the engaging portion 123 to deform after abutting against the first surface 1231. In some embodiments, the engaging portion 123 may not be provided with the first surface 1231, and by providing the first surface 1231 on the mating member 220, the deformation displacement of the engaging portion 123 can still be realized, and the specific principle is the same as or similar to that of providing the first surface 1231 on the engaging portion 123, which will not be elaborated herein.

[0045] Correspondingly, the engaging portion 123 may further be provided with a second surface 1232 for engaging with the mating member 220. Wherein, after the inserting portion 122 is inserted into the predetermined position of the mating member 220, the engaging portion 123 is reset by its own deformation force, and the second surface 1232 can be used to form a perpendicular fastening structure with the mating member 220 to realize the engagement of the engaging portion 123 and the mating member 220 in the thickness direction X. In this embodiment, since the inserting portion 122 and the mating member 220 are obliquely fastened, the second surface 1232 may also be an inclined surface, and the inclination direction may be perpendicular to the inclination direction of the inserting portion 122, so that the engaging portion 123 can be engaged with the mating member 220 through the second surface 1232 in the inclination direction of the inserting portion 122, preventing the inserting portion 122 from disengaging from the mating member 220 in the inclination direction.

[0046] Further, as Figures 5 to 6As shown, in order to ensure the deformation amount of the clamping portion 123, the clamping portion 123 may be provided with a first portion 1233 and a second portion 1234. One end of the first portion 1233 may be connected to the side wall of the through groove 1212, and the other end may be bent and disposed in the through groove 1212. The second portion 1234 may be connected to the other end of the first portion 1233 and extend into the receiving groove 1211 for being clamped with the mating member 220 in the thickness direction X when the plugging portion 122 is inserted into the mating member 220. The first surface 1231 and the second surface 1232 may be disposed at the end of the second portion 1234 away from the first portion 1233. With such a setting, the bent first portion 1233 can increase the deformation amount of the clamping portion 123 and reduce the probability of the clamping portion 123 breaking during the process of being pushed by the mating member 220.

[0047] For the detachable structure 300 provided by the embodiment of the present application, by inserting the plugging portion 122 into the mating member 220 in the thickness direction X and the clamping portion 123 being clamped with the mating member 220 in the thickness direction X, the assembly of the watch band 100 and the watch head 200 can be realized. At the same time, due to the adoption of the assembly method of plugging the plugging portion 122 and the mating member 220 in the thickness direction, the lateral tensile strength of the watch band 100 can also be improved, meeting the test requirement of withstanding a lateral tensile force of 100 N and ensuring the assembly reliability of the watch band 100 and the watch head 200.

[0048] Please refer to Figures 7 to 12 , Figure 7 is Figure 2 the exploded structural schematic diagram of the watch head 200 in Figure 8 is Figure 7 the connection structural schematic diagram of a part of the housing 210, the mating member 220, the pushing member 230 and the reset member 240 in Figure 9 is Figure 8 the partial cross-sectional structural schematic diagram of a part of the housing 210, the mating member 220 and the pushing member 230 along VI-VI in Figure 10 is Figure 8 the partial cross-sectional structural schematic diagram of a part of the housing 210, the mating member 220 and the pushing member 230 along VI-VI at another position in Figure 11 is Figure 9 the connection structural schematic diagram of the housing 210 and the mating member 220 in Figure 12 is Figure 9 the structural schematic diagram of the pushing member 230 in

[0049] The watch head 200 may have an image display function, and the user can view corresponding data information through the watch head 200, such as time, temperature, weather, two-dimensional code, and number of walking steps, etc. As Figures 7 to 8As shown in the figure, the watch head 200 may include: a housing 210, a fitting 220, a pushing member 230, a reset member 240, a display screen 250, and a back cover 260. Among them, the housing 210 may be used to connect with the watch band 110. The fitting 220 may be disposed on the outer wall surface of the housing 210 and is used to cooperate with the connecting member 120 to achieve the assembly of the watch band 100 and the watch head 200. The pushing member 230 is movably disposed on the fitting 220 and is used to release the clamping state between the connecting member 120 and the fitting 220 to achieve the disassembly of the watch band 100 and the watch head 200. The reset member 240 is connected to the pushing member 230 and is used to drive the pushing member 230 to reset after the pushing member 230 moves. The display screen 250 may be covered on one side of the housing 210 and is used to provide image display for the watch head 200. The back cover 260 may be covered on the other opposite side of the housing 210 to protect the electronic devices inside the watch head 200. In this embodiment, the insertion portion 122 may be inserted into the fitting 220 in the thickness direction X. After the insertion portion 122 is inserted into the fitting 220, the clamping portion 123 may be clamped with the fitting 220 in the thickness direction X to achieve the assembly of the watch band 100 and the watch head 200. The pushing member 230 may push the clamping portion 123 to displace, so that the clamping portion 123 is separated from the fitting 220 to achieve the disassembly of the watch band 100 and the watch head 200. It should be noted that the connecting member 120, the fitting 220, the pushing member 230, and the reset member 240 may constitute a detachable structure 300 of the wearable device 10 to achieve the detachable connection between the watch band 100 and the watch head 200.

[0050] Specifically, the outer wall surface 211 of the housing 210 may be used to mount the fitting 220, so as to facilitate the cooperation with the connecting member 120 in the thickness direction X to achieve the detachable connection between the watch band 100 and the watch head 200. As Figures 8 to 9As shown, the outer wall surface 211 of the housing 210 can also be tilted toward the direction of the back cover 250, so that the matching piece 220 on the outer wall surface 211 can also be tilted toward the back cover 250. When the strap body 110 is assembled with the matching piece 220 through the connecting piece 120, the strap body 110 can also be tilted toward the user's wrist, so as to fit the user's wrist and improve the fit of the user wearing the wearable device 10. In this embodiment, the housing 210 can be the middle frame of the watch head 200, and the matching piece 220 and the housing 210 can also be an integral structure to improve the connection strength between the two. At the same time, the housing 210 can also have an accommodating space 2101. The accommodating space 2101 can be used to accommodate various functional devices required by the wearable device 10, such as batteries, microphones, speakers, cameras, and sensors, etc., to realize the corresponding functional applications of the wearable device 10. At the same time, the material of the housing 210 can be glass, metal, hard plastic, etc., so that the housing 210 can have a certain structural strength and play a certain supporting and protective role. In addition, since the housing 210 is generally directly exposed to the external environment, the housing 210 may preferably have certain wear-resistant, corrosion-resistant, and scratch-resistant properties, or a layer of wear-resistant, corrosion-resistant, and scratch-resistant functional material may be coated on the outer surface of the housing 210. In some embodiments, the mating piece 220 and the housing 210 may also be two independent components, and the two may be connected by a fixing method such as welding, bonding, and bolting.

[0051] The matching piece 220 can be disposed on the outer wall surface 211 of the housing 210 to match the connecting piece 120 to realize the assembly of the watch band 100 and the watch head 200. Figures 9 to 11 As shown, the fitting member 220 may include: a fitting portion 221 and a limiting portion 222. The fitting portion 221 may be arranged on the outer wall surface 211 of the housing 210, and the limiting portion 222 may be arranged on the side of the fitting portion 221 away from the outer wall surface 211. In this embodiment, the plug-in portion 122 may be inserted into the fitting portion 221 in the thickness direction X. After the plug-in portion 122 is inserted into the fitting portion 221, the limiting portion 222 may be engaged with the clamping portion 123 in the thickness direction X, thereby limiting the movement of the plug-in portion 122 in the thickness direction X, preventing the plug-in portion 122 from being disengaged from the fitting portion 221, and realizing the assembly of the watch band 100 and the watch head 200. The pushing member 230 may be movably arranged on the fitting portion 221, and is used to push the clamping portion 123 to deform, so as to release the clamping state between the clamping portion 123 and the limiting portion 222, and realize the disassembly of the watch band 100 and the watch head 200. The reset member 240 may be disposed between the pushing member 230 and the matching portion 221 to achieve the reset function of the pushing member 230 , thereby providing an escape space for the next clamping of the clamping portion 123 and the limiting portion 222 .

[0052] Specifically, the mating part 221 may be provided with a slot 2211, enabling the plugging part 122 to be inserted into the mating part 221 through the slot 2211, thereby realizing the assembly of the connecting member 120 and the mating member 220. Among them, the slot 2211 may penetrate the mating part 221 in the thickness direction X, avoiding the problem of interference between the plugging part 122 and the bottom wall of the slot 2211 after the plugging part 122 is inserted into the slot 2211. In this embodiment, the slot 2211 may be obliquely provided on the mating part 221, and the oblique direction may be adapted to the oblique direction of the plugging part 122, so that the plugging part 122 can be obliquely latched with the mating part 221, improving the firmness of the latching between the two. At the same time, the number of slots 2211 may be two, to be adapted to the two plugging parts 122 of the connecting member 120. Correspondingly, the limiting part 222 may be arranged between the two slots 2211, to be adapted to the latching part 123 between the two plugging parts 122. In some embodiments, the arrangement positions of the plugging part 122 and the slot 2211 may also be interchanged, that is, the connecting member 120 may be provided with the slot 2211, while the mating member 220 may be provided with the plugging part 122, as long as the connecting member 120 can be plugged with the mating member 220 in the thickness direction X.

[0053] Furthermore, the mating part 221 may also be slidably connected to the pushing member 230, so that the pushing member 230 can be movably arranged on the mating part 221. As Figure 8 and Figure 11As shown, the mating portions 221 are arranged opposite to each other, and sliding grooves 2212 can be formed on both sides parallel to the thickness direction X. The pushing member 230 can be disposed on one side of the mating portion 221 in the thickness direction, and a partial area of the pushing member 230 can be disposed in the sliding groove 2212, so that the pushing member 230 can slide along the side wall of the sliding groove 2212 in the thickness direction X, thereby realizing the sliding connection between the pushing member 230 and the mating portion 221. At the same time, in order to prevent the pushing member 230 from disengaging from the sliding groove 2212, a retaining wall 2213 is further provided in the sliding groove 2212, and the retaining wall 2213 is configured to be engaged with the pushing member 230 when the pushing member 230 moves in a direction away from the mating portion 221. Thus, when the pushing member 230 slides in the sliding groove 2212 in a direction away from the mating portion 221, the retaining wall 2231 can block the pushing member 230, thereby preventing the pushing member 230 from disengaging from the sliding groove 2212. In addition, a receiving groove 2214 can be formed on one side of the mating portion 221 facing away from the outer wall surface 214, and the receiving groove 2214 can penetrate the mating portion 221 in the thickness direction X. Wherein, the receiving groove 2214 can be used to receive the engaging portion 123 after the plugging portion 122 is inserted into the slot 2211, so as to prevent the engaging portion 123 from occupying other spaces on the mating portion 221. That is, after the plugging portion 122 is inserted into the slot 2211, the engaging portion 123 can be inserted into the receiving groove 2214 to be engaged with the limiting portion 222. Correspondingly, the receiving groove 2214 can also communicate with the pushing member 230, so that the pushing member 230 can move into the receiving groove 2214 to push the engaging portion 123 to release the engaged state between the connecting member 120 and the mating member 220.

[0054] The limiting portion 222 can be disposed in the receiving groove 2214, and the limiting portion 222 can be located on the moving path of the engaging portion 123 in the thickness direction X. When the plugging portion 122 is inserted into the slot 2211, the engaging portion 123 can be inserted into the receiving groove 2214 from the thickness direction X, and the limiting portion 222 can abut against the engaging portion 123 and push the engaging portion 123 to deform, so that the engaging portion 123 is displaced relative to the main body portion 121, thereby ensuring that the plugging portion 122 is normally inserted into the slot 2211. As Figures 9 to 11As shown, the limiting part 222 can be provided with a third surface 2221, and the third surface 2221 can be an inclined surface for abutting against the first surface 1231 of the clamping part 123 to generate an abutting force to push the clamping part 123 to deform, so that the clamping part 123 can be displaced relative to the main body part 121. Wherein, the third surface 2221 and the first surface 1231 can be arranged in parallel to improve the smoothness of the limiting part 222 pushing the clamping part 123 to deform. In some embodiments, the third surface 2221 can also be an arc surface, as long as the limiting part 222 can push the clamping part 123 to displace through the third surface 2221. In addition, in some other embodiments, the clamping part 123 can also be pushed by other parts of the matching part 221, as long as the clamping part 123 can deform and displace relative to the main body part 121.

[0055] Further, a fourth surface 2222 can be provided on the side of the limiting part 222 opposite to the third surface 2221, and the fourth surface 2222 is configured to be in contact with the clamping part 123 in the thickness direction X, so as to realize the clamping of the clamping part 123 and the limiting part 222 in the thickness direction X. During the process of inserting the insertion part 122 into the slot 2211, the first surface 1231 and the third surface 2221 can change from the abutting state to the separated state as the insertion part 122 is inserted. When the insertion part 122 is inserted into the slot 2211 to a predetermined position and the first surface 1231 and the third surface 2221 are separated, the clamping part 123 can be reset under its own deformation force. At this time, the second surface 1232 of the clamping part 123 can be buckled on the fourth surface 2222 of the limiting part 222, and the clamping part 123 and the limiting part 222 are clamped in the thickness direction X. In this embodiment, the fourth surface 2222 can also be an inclined surface, and the fourth surface 2222 can also be arranged in parallel with the second surface 1232, so that the two can be closely attached when they are clamped, improving the firmness of the clamping between the clamping part 123 and the limiting part 222. In addition. On the side of the limiting part 222 opposite to the pushing part 230, that is, the side of the limiting part 222 where the fourth surface 2222 is provided, a groove 2223 can also be provided, and the groove 2223 can be located on the moving path of the pushing part 230. The groove 2223 is used to provide the moving space required for the pushing part 230 to push the clamping part 123 to displace, and to prevent the pushing part 230 from interfering with the limiting part 222 during the process of pushing the clamping part 123 to displace.

[0056] The pushing part 230 can be movably arranged on the matching part 220, and it can be used to push the clamping part 123 to deform, so that the clamping part 123 can be displaced relative to the main body part 121, so as to release the clamping state with the limiting part 222. As Figures 8 to 9As shown, the pusher 230 can be disposed on one side of the mating portion 221 in the thickness direction X, and the moving direction of the pusher 230 can be parallel to the thickness direction X. At the same time, the pusher 230 can also be provided with a fifth surface 2301, and the fifth surface 2301 can be an inclined surface. When the pusher 230 moves relative to the mating portion 221 in the thickness direction X, the fifth surface 2301 can abut against the first surface 1231 of the engaging portion 123, thereby generating a pushing force to deform the engaging portion 123, so that the engaging portion 123 is displaced in a direction away from the limiting portion 222, releasing the engaging state between the engaging portion 123 and the limiting portion 222, and realizing the disassembly of the watch band 100 and the watch head 200. In this embodiment, the fifth surface 2301 can be arranged parallel to the first surface 1231, so that the first surface 1231 and the fifth surface 2301 can be closely attached when they abut. In some embodiments, the fifth surface 2301 can also be an arc surface, as long as the pusher 230 can push the engaging portion 123 to deform through the fifth surface 2301, so that the engaging portion 123 is disengaged from the limiting portion 222.

[0057] Specifically, as Figure 12As shown, the pusher 230 may include: a pressing portion 231, a sliding portion 232, and a pushing portion 233. Among them, the pressing portion 231 may be disposed on one side of the mating portion 221 in the thickness direction X and is disposed opposite to the mating portion 221. The sliding portion 232 may be disposed on both sides opposite to the pressing portion 231 and extends in a direction close to the mating portion 221. The pushing portion 233 may be disposed on a side of the limiting portion 222 close to the limiting portion 222 and is disposed opposite to the groove 2223 on the limiting portion 222. The pressing portion 231 can be pressed by the user to enable the pusher 230 to move relative to the mating portion 221. The sliding portion 232 may be disposed in the sliding groove 2212 and can slide along the side wall of the sliding groove 2212 in the thickness direction X to enable the pusher 230 to move in the thickness direction X. At the same time, a buckle 2321 may be provided at an end of the sliding portion 232 away from the pressing portion 231, and during the sliding process of the buckle 2321 in the thickness direction X, it can be engaged with the retaining wall 2213 in the sliding groove 2212, thereby preventing the sliding portion 232 from disengaging from the sliding groove 2212. The pushing portion 233 may be inclinedly disposed on the pressing portion 231 such that the pushing portion 233 may have an inclined surface, that is, the fifth surface 2301. When the pusher 230 moves in the thickness direction X, the pushing portion 233 may move in a direction close to the limiting portion 222, and the groove 2223 may provide an avoidance space for the movement of the pushing portion 233, so that the fifth surface 2301 can abut against the first surface 1231 of the engaging portion 123 to generate an abutting force to push the engaging portion 123 to deform, thereby releasing the engaged state between the engaging portion 123 and the limiting portion 222. In the above manner, when the user needs to disassemble the watch band 100 and the watch head 200, a force can be applied to the pressing portion 231 in the thickness direction X, so that the pushing portion 233 moves in the thickness direction X, and the fifth surface 2301 is used to push the engaging portion 123 to form, thereby releasing the engaged state between the engaging portion 123 and the limiting portion 222 and realizing the disassembly of the watch band 100 and the watch head 200.

[0058] Please refer to Figure 13 , Figure 13 is Figure 8 a partial cross-sectional structural schematic diagram of the housing 210, the mating member 220, the pusher 230, and the reset member 240 along VI-VI in

[0059] The reset member 240 may be disposed on the pusher 230 and is used to drive the pusher 230 to reset after the pusher 230 moves, thereby providing an avoidance space for the next engagement between the engaging portion 123 and the limiting portion 222. As Figure 13As shown, the reset member 240 can be disposed between the mating portion 221 and the pressing portion 231, and one end of the reset member 240 can be connected to the mating portion 221, and the other opposite end can be connected to the pressing portion 231. Among them, the reset member 240 can have the ability of elastic deformation. When the pressing portion 231 moves in the thickness direction X, the reset member 240 can be deformed, and then generate a deformation acting force to drive the pressing portion 231 to reset. In this embodiment, the reset member 240 can be a compression spring, so that the pushing member 230 can use the elastic force generated by the spring to reset. In some embodiments, the reset member 240 can also be other components with deformation ability, as long as the reset member 240 can generate a deformation acting force to drive the pushing member 230 to reset. Or, the reset member 240 can also use repulsive magnets for reset. By respectively arranging opposite and same-pole magnets on the mating portion 221 and the pressing portion 231, after the pressing portion 231 moves, it can also be reset by the repulsive force generated by the two magnets.

[0060] Please refer to Figures 14 to 15 , Figure 14 is Figure 1 a partial cross-sectional structural schematic diagram of the wearable device 10 along VII-VII in Figure 15 is Figure 1 a partial cross-sectional structural schematic diagram of the wearable device 10 along VII-VII at another position in

[0061] As Figures 14 to 15As shown, during the assembly process of the watch band 100 and the watch head 200, the insertion part 122 can be inserted into the slot 2211 in the thickness direction X. As the insertion part 122 is inserted, the clamping part 123 can be abutted against the third surface 2221 of the limiting part 222 by using the first surface 1231, so as to generate a reaction force to push the clamping part 123 to deform. When the insertion part 122 is inserted to a predetermined position, the clamping part 123 can be reset under its own deformation force, so that its second surface 1232 can be clamped with the fourth surface 2222 of the limiting part 222 in the thickness direction X, thereby restricting the movement of the insertion part 122 in the thickness direction X and preventing the insertion part 122 from disengaging from the slot 2211, realizing the assembly of the watch band 100 and the watch head 200. During the disassembly process of the watch band 100 and the watch head 200, the pressing part 231 can move in the thickness direction X. As the pressing part 231 moves, the pushing part 233 can be abutted against the first surface 1231 of the clamping part 123 by using the fifth surface 2301, so as to generate a reaction force to push the clamping part 123 to deform and release the clamping state with the limiting part 222, so that the insertion part 122 can be disengaged from the slot 2211, realizing the disassembly of the watch band 100 and the watch head 200. In the above way, when the user needs to assemble the watch band 100 and the watch head 200, only need to insert the insertion part 122 into the slot 2211 in the thickness direction X to complete the assembly. When the user needs to disassemble the watch band 100 and the watch head 200, only need to push the clamping part 123 to deform by pressing the pushing member 230 to complete the disassembly. The whole disassembly and assembly process is simple, convenient and easy to operate, improving the convenience of the user to disassemble and assemble the watch band 100 and the watch head 200. At the same time, since the insertion part 122 is inserted into the fitting part 220 in the thickness direction X for assembly, the lateral tensile strength of the watch band 100 can also be improved, ensuring the assembly reliability of the watch band 100 and the watch head 200.

[0062] Please refer to Figures 16 to 18 , Figure 16 is Figure 1 a partial cross-sectional structural schematic diagram of the wearable device 10 along VII-VII in another embodiment, Figure 17 is Figure 16 a connection structural schematic diagram of the connecting member 120, the clamping member 123a, the elastic member 130 and the cover plate 140 in Figure 18 is Figure 17 a cross-sectional structural schematic diagram of the connecting member 120, the clamping member 123a, the elastic member 130 and the cover plate 140 along XI-XI in

[0063] In some embodiments, in addition to utilizing the deformation of the clamping portion 123 itself to achieve the displacement and reset of the clamping portion 123 during the insertion of the insertion portion 122, a component with deformation ability can also be independently provided to achieve the displacement and reset of the clamping portion 123 during the insertion of the insertion portion 122. The difference between the watch band 100 provided in this embodiment and the above embodiment is that the connecting member 120 only includes the main body portion 121 and the insertion portion 122, while the clamping portion 123 is a component independent of the connecting member 120. Hereinafter, the clamping portion 123 is described as an independent clamping member 123a.

[0064] Since the clamping member 123a itself does not have the ability to deform, the watch band 100 can also be provided with an elastic member 130 to achieve the displacement and reset of the clamping member 123a during the insertion of the insertion portion 122. As Figures 16 to 18 shown, the elastic member 130 can be a spring, and the clamping member 123a can be disposed in the receiving groove 1211, and the clamping member 123a can also extend into the through groove 1212 and be slidably connected to the side wall of the through groove 1212. The elastic member 130 can be a spring, and the elastic member 130 can be disposed in the receiving groove 1211. Wherein, the two relatively arranged ends of the elastic member 130 can be respectively connected to the clamping member 123a and the side wall of the receiving groove 1211. Thus, when the insertion portion 122 is inserted into the slot 2211 from the thickness direction X, the clamping member 123a can move in the thickness direction X along with the insertion of the insertion portion 122, so as to abut against the limiting portion 222, such that the clamping member 123a can be displaced relative to the main body portion 121 under the pushing of the limiting portion 222. After the insertion portion 122 is inserted to a predetermined position, the clamping member 123a can be reset under the driving of the deformation force generated by the elastic member 130 and be clamped with the limiting portion 222 in the thickness direction X to achieve the assembly of the watch band 100 and the watch head 200. Correspondingly, the pushing member 230 can still push the clamping member 123a to displace relative to the main body portion 121 to release the clamping state between the clamping member 123a and the limiting portion 222. It should be noted that the connecting member 120, the clamping member 123a, the mating member 220, the pushing member 230, and the elastic member 130 in this embodiment can also constitute a detachable structure 300 of the wearable device 10 to achieve the detachable connection between the watch band 100 and the watch head 200, but the detachable structure 300 is not limited to only including the above components.

[0065] Specifically, the snap-in member 123a can still be provided with a first surface 1231 and a second surface 1232, so as to abut the first surface 1231 against the limiting portion 222 to generate an abutting force to push the snap-in member 123a to displace, and to snap the second surface 1232 with the limiting portion 222 in the thickness direction X. The specific principle is the same as or similar to that of the above embodiment, and will not be elaborated here. The difference between the snap-in member 123a provided in this embodiment and the snap-in portion 123 of the above embodiment is that the snap-in member 123a can be slidably connected to the main body portion 121 to realize the displacement of the snap-in member 123a under the pushing of the limiting portion 222. As Figure 17 and Figure 18 shown, a slideway 12121 can be convexly provided on the side wall of the through groove 1212, and a partial area of the snap-in member 123a can be buckled on the slideway 12121, so that the snap-in member 123a can slide relative to the main body portion 121 along the slideway 12121. By buckling the snap-in member 123a on the slideway 12121, not only can the sliding of the snap-in member 123a relative to the main body portion 121 be realized, but also the slideway 12121 can be used to limit the movement of the snap-in member 123a in the direction away from the mating member 220 of the pushing member 230, thereby preventing the snap-in member 123a from moving relative to the main body portion 121 in the thickness direction X and affecting the snap-fastening firmness between the snap-in member 123a and the limiting portion 222 in the thickness direction X. In this embodiment, the extending direction of the slideway 12121 can be perpendicular to the thickness direction X. In some embodiments, a separate component for restricting the movement of the snap-in member 123a in the thickness direction X can also be provided on the main body portion 121, as long as it is ensured that the snap-in member 123a will not move in the thickness direction X.

[0066] Furthermore, the watchband 100 may also be provided with a cover plate 140, and the cover plate 140 may be provided to cover the opening of the through slot 1212 away from the receiving slot 1211, so as to cover the clamping member 123a in the through slot 1212 and limit the movement of the clamping member 123a in the direction in which the pusher 230 approaches the mating member 220, thereby preventing the clamping member 123a from moving relative to the main body 121 in the thickness direction X, thereby affecting the clamping firmness of the clamping member 123a and the limiting portion 222 in the thickness direction X. Among them, a boss 12122 may also be provided in the opening of the through slot 1212 away from the receiving slot 1211, and the clamping member 123a may be provided flush with the side of the boss 12122 away from the receiving slot 2214, so that the cover plate 140 can not only cover the through slot 1212 through the boss 12122, but also limit the movement of the clamping member 123a. At the same time, the side of the cover plate 140 that is away from the clamping member 123a can be flush with the outer surface of the main body 121, thereby improving the appearance consistency of the cover plate 140 and the main body 121. In this embodiment, the clamping member 123a is independently provided on the main body 121 and is slidably connected, so that the clamping member 123a can be displaced under the push of the limiter 222, thereby ensuring that the plug-in part 122 is normally inserted into the slot 2211. In addition, by providing an elastic member 130 between the main body 121 and the clamping member 123a, the clamping member 123a can be reset by the deformation force of the elastic member 130 after displacement, and be clamped with the limiter 222 in the thickness direction X, so that the assembly of the watch band 100 and the watch head 200 can still be achieved.

[0067] See also Figures 19 to 20 , Figure 19 yes Figure 16 A schematic diagram of the connection structure of the middle housing 210, the matching member 220 and the pushing member 230, Figure 20 yes Figure 19 Schematic diagram of the partial cross-sectional structure of the middle shell 210, the matching member 220 and the pushing member 230 along line IX-IX.

[0068] like Figures 19 to 20 As shown, the difference from the above embodiment is that, in this embodiment, since the clamping member 123a is slidably connected to the main body 121 and needs to be reset by the elastic member 230, the matching portion 221 is also provided with a notch 2202 connected to the receiving groove 2214 on the sliding path of the clamping member 123a, thereby providing an escape space for the sliding of the clamping member 123a under the push of the limiting portion 222 or the pushing portion 223. In addition, in addition to being used to accommodate the clamping member 123a, the receiving groove 2214 in this embodiment can also be used to limit the movement of the pushing member 230 to prevent the pushing member 230 from falling off the matching portion 221. Figures 19 to 20As shown, a partial area of the pushing portion 233 of the pusher 230 can be located within the receiving groove 2214. The sliding portions 232 can be disposed on two opposite sides of the pushing portion 233, and a partial area of the sliding portions 232 can also be located within the receiving groove 2214. Among them, the sliding portions 232 can slide along the inner wall of the receiving groove 2214 and can be engaged with the inner wall of the receiving groove 2214 in the direction away from the engaging portion 221 of the pusher 230. For example, a protrusion 2203 can be provided on the side wall of the receiving groove 2214, and the buckle 2321 of the sliding portion 232 can be buckled on the protrusion 2203. With such a setting, when the pusher 230 moves in the direction of approaching the engaging member 220, the pushing portion 233 can push the engaging member 123a to slide in the direction away from the limiting portion 222 to release the engaged state between the engaging member 123a and the limiting portion 222. The sliding portions 232 can also slide into the receiving groove 2214 along with the movement of the pushing portion 233, so that the buckle 2321 can move in the direction away from the protrusion 2203 and be separated from the protrusion 2203 to achieve the pressing and sliding of the pusher 230. When the pusher 230 moves in the direction away from the engaging member 220, the buckle 2321 of the sliding portion 232 can move in the direction of approaching the protrusion 2203 and be engaged with the protrusion 2203, thereby preventing the pusher 230 from being disengaged from the receiving groove 2214. Correspondingly, the reset member 240 can still be connected to the pusher 230 and the engaging member 220 to implement the reset function of the pusher 230. The specific setting method can be the same as or similar to that of the above embodiment, and will not be elaborated herein.

[0069] As Figure 7 shown, the display screen 250 can be disposed on the display surface of the housing 210. It can use an OLED (Organic Light-Emitting Diode) screen for image display or an LCD (Liquid Crystal Display) screen for image display. The rear cover 260 can be disposed on the side of the housing 210 facing away from the display screen 250 to protect the electronic devices within the accommodation space 2101. In some embodiments, the head 200 can also be a module with a single function, such as heart rate detection, blood pressure / oxygen saturation measurement, and body temperature detection.

[0070] For the detachable structure provided by the embodiments of the present application, when assembling the watch band 100 and the watch head 200, the connecting member 120 is inserted into the mating member 220 in the thickness direction X of the watch band 100, and then after the connecting member 120 and the mating member 220 are inserted, the engaging portion 123 is engaged with the limiting portion 222 in the thickness direction X, so that the connecting member 120 and the mating member 220 can be engaged with each other, thereby realizing the assembly of the watch band 100 and the watch head 200. When it is necessary to disassemble the watch band 100 and the watch head 200, the movable pushing member 230 is used to push the engaging portion 123 to displace relative to the watch band 100, so that the engaging portion 123 can be separated from the limiting portion 222, and the engaging state between the connecting member 120 and the mating member 220 is released, thereby realizing the disassembly of the watch band 100 and the watch head 200. By the above method, the convenience and operability of the watch band 100 and the watch head 200 during the disassembly and assembly process can be improved. At the same time, by using the connecting member 120 and the mating member 220 to cooperate and insert in the thickness direction X, the lateral tensile force that the watch band 100 and the watch head 200 can withstand can also be increased.

[0071] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
