[0067] The technical solutions in some embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0068] A wearable device is a portable electronic device that can be worn on the body. With the development of electronic technology, various types of wearable devices have emerged, such as smart watches, smart bracelets, smart glasses, etc. Wearable devices have diversified functions, convenient operation and interaction, fashionable appearance and design, long-lasting and durable characteristics, and can provide users with a more intelligent, convenient and healthy lifestyle.

[0069] The wearable device is mainly composed of a device body and a fixed strap. The fixed strap is used to wear the device body on the body, and the fixed strap and the device body are detachably connected to facilitate replacement of the fixed strap. How to design the detachable connection structure between the fixed strap and the device body directly affects the disassembly efficiency between the fixed strap and the device body, and has become one of the important topics in the industry.

[0070] In the related art, a wearable device is connected between a fixing band and a device main body through an ear, and when the fixing band is detached, a tool is needed, so that the fixing band is inconvenient to detach.

[0071] In order to facilitate the detachment of the fixing band, in the related art, another wearable device is connected between the fixing band and the device main body through a clamping structure with an unlocking button, when the fixing band is installed with the device main body, the device main body is clamped with the fixing band through a clamping piece, and the unlocking button limits the movement of the clamping piece to lock the clamping piece; when the fixing band needs to be detached, the unlocking button is pressed, the unlocking button releases the movement lock of the clamping piece, and the clamping piece can be separated from the fixing band, so as to realize the detachment of the fixing band and the device main body.

[0072] However, in the related art, the wearable device is connected between the fixing band and the device main body through the clamping piece and the unlocking button to realize clamping and unlocking, and the unlocking button and the clamping piece need to be movably connected, which not only increases the number of parts, but also makes the detachable connection structure between the fixing band and the device main body more complex, which is not conducive to improving the connection reliability.

[0073] Therefore, the embodiments of the present application provide a wearable device, a fixing band thereof and a device main body, the clamping piece is arranged on the band body of the fixing band, and the clamping and unlocking are realized by rotating the clamping piece to different positions, so that the unlocking part movably connected with the clamping piece is not needed, thereby simplifying the detachable connection structure between the fixing band and the device main body, and further improving the connection reliability between the fixing band and the device main body.

[0074] The wearable device in the embodiments of the present application can be an electronic device such as a smart watch, a smart bracelet, smart glasses and the like which can be worn on the body, and the detachable connection structure between the fixing band and the device main body will be specifically introduced below taking the smart watch as an example, and the detachable connection structure of other types of wearable devices can be arranged according to the detachable connection structure of the smart watch, which will not be described here.

[0075] Fig. 1 is a structural schematic diagram of a wearable device (smart watch) in some embodiments of the present application, Fig. 2 is a structural schematic diagram of the wearable device in Fig. 1 from another perspective, and Fig. 3 is an exploded view of the wearable device in Fig. 1.

One end of each of the fixing band 100a and the fixing band 100b is detachably connected to the opposite sides of the device body 200. The fixing band 100a and the fixing band 100b are connected together through a lock buckle structure, so that the fixing band 100a, the fixing band 100b and the device body 200 form a ring structure, which can be sleeved on a human body (such as a wrist), thereby achieving wearing the wearable device on the human body. It should be noted that the fixing band 100a and the fixing band 100b can also be connected in other ways other than the lock buckle structure, and the embodiments of the present application are not limited thereto.

[0077] FIG. 4 is a structural schematic view of the device body 200 of the wearable device in FIG. 1, and FIG. 5 is an A-A sectional view of the device body in FIG. 4. As shown in FIG. 4 and FIG. 5, the device body 200 is provided with a first clamping groove 210. The first clamping groove 210 has a groove bottom wall 211, a first groove side wall 212 and a second groove side wall 213 which are respectively arranged at the opposite side edges of the groove bottom wall 211. The first groove side wall 212 is provided with a second clamping groove 220.

[0078] The groove bottom wall 211 is the groove wall opposite to the slot in the first clamping groove 210. As shown in FIG. 5, the second clamping groove 220 can be arranged at the position of the first groove side wall 212 close to the groove bottom wall 211 of the first clamping groove 210, i.e., the side groove side wall of the second clamping groove 220 is flush with the groove bottom wall 211 of the first clamping groove 210. However, the second clamping groove 220 can also be arranged at other positions of the first groove side wall 212.

[0079] The device body 200 is the core part of the wearable device, which is used to realize specific functions, such as health monitoring, motion tracking, notification reminding, etc. The device body 200 includes a shell 250 and a cover plate 240. One side of the shell 250 has an opening, and the cover plate 240 is arranged at the opening of the shell 250. The inner side of the cover plate 240 is used to arrange functional components such as a display screen, a circuit board, a battery, etc.

[0080] As shown in FIG. 4 and FIG. 5, the number of the first clamping grooves 210 is two, and the two first clamping grooves 210 are respectively arranged on the opposite side walls of the shell 250. Each of the first clamping grooves 210 is clamped with the corresponding fixing band 100. In the thickness direction H of the device body 200, the first groove side wall 212 of the first clamping groove 210 is arranged at the side of the first clamping groove 210 close to the cover plate 240, and the second groove side wall 213 is arranged at the side of the first clamping groove 210 away from the cover plate 240.

[0081] As shown in FIG. 5 and FIG. 6, which is an exploded view of the device body 200 shown in FIG. 4. The shell 250 includes a middle frame 251 and a back cover 252, the middle frame 251 is a metal or alloy piece, and the back cover 252 is a plastic piece, the middle frame 251 is disposed between the cover plate 240 and the back cover 252.

[0082] In order to reduce the deformation of the back cover 252 under external force, in some embodiments, as shown in FIG. 5 and FIG. 6, the edge of the back cover 252 has a notch 2521, and the middle frame 251 integrally has a flange 2511, and the flange 2511 is inserted into the notch 2521. Since the flange 2511 is a metal or alloy piece, the hardness of the flange 2511 is greater than that of the back cover 252. By inserting the flange 2511 into the notch 2521, the flange 2511 can support and reinforce the back cover 252, thereby facilitating the reduction of deformation of the back cover 252 under external force.

[0083] As shown in FIG. 6, the second groove side wall 213 is disposed on the flange 2511, and the middle frame 251 and the back cover 252 form the first clamping groove 210.

[0084] Of course, the device body 200 is not limited to the above structure, and the device body 200 can also be specifically provided with other structures according to the type of the wearable device. For example, the shell 250 can include the cover plate 240 and the back cover 252, and can not include the middle frame 251.

[0085] FIG. 7 is a partial view of the fixing band 100 of the wearable device in FIG. 1, FIG. 8 is a B-B sectional view of the fixing band 100 in FIG. 7, and FIG. 9 is an exploded view of the fixing band 100 in FIG. 7. As shown in FIG. 7 and FIG. 8, the fixing band 100 includes a band body 110 and a clamping piece 120 disposed at one end of the band body 110. The clamping piece 120 includes a clamping piece body 121 and a protruding portion 122, the clamping piece body 121 has opposite first and second end portions 121a and 121b, the protruding portion 122 is disposed at the first end portion 121a and protrudes from the clamping piece body 121 in a direction away from the second end portion 121b (i.e. upward in FIG. 8), and the clamping piece body 121 is rotatably connected to the band body 110 by a rotating shaft 123.

[0086] As shown in FIG. 7 and FIG. 8, the protruding portion 122 and the clamping piece body 121 are an integral structure, but are not limited thereto, and the protruding portion 122 and the clamping piece body 121 can also be separately provided, and the protruding portion 122 is fixed to the clamping piece body 121. It can be understood that the up-down direction in FIG. 8 can be understood as the height direction H of the protruding portion 122.

[0087] In some embodiments, as shown in FIG. 7, FIG. 8 and FIG. 9, the band 110 comprises a first band surface 111 and a second band surface 112 arranged oppositely, and a band end surface 113 connected between the first band surface 111 and the second band surface 112, the first band surface 111 is an appearance surface of the band 110, the second band surface 112 is provided with a clamping piece accommodating groove 114, the clamping piece accommodating groove 114 penetrates the band end surface 113, at least a part of the clamping piece 120 is arranged in the clamping piece accommodating groove 114, the protruding portion 122 protrudes out of the clamping piece accommodating groove 114 and protrudes out of the band end surface 113.

[0088] By arranging at least a part of the clamping piece 120 in the clamping piece accommodating groove 114, the space occupied by the clamping piece 120 outside the band 110 can be reduced, so that the structure of the fixing bandage 100 is more compact; at the same time, the clamping piece accommodating groove 114 can protect the clamping piece 120 and reduce damage to the surface of the clamping piece 120 by other objects in the external environment.

[0089] As shown in FIG. 9, the clamping piece main body 121 can be rotatably connected with the groove side wall of the clamping piece accommodating groove 114 through the rotating shaft 123.

[0090] Of course, the end of the band 110 can also not be provided with the clamping piece accommodating groove 114, and the band 110 is partially thinned at the end to form a thinned section, and the clamping piece 120 is arranged inside the thinned section of the band 110.

[0091] In some embodiments, as shown in FIG. 9 and FIG. 10, FIG. 10 is a schematic diagram of the installation of the rotating shaft 123 of the fixing bandage 100 in FIG. 7. The inside of the band 110 is embedded with a rotating piece 130, the clamping piece 120, the rotating shaft 123 and the rotating piece 130 are metal or alloy pieces, the band 110 is a plastic piece, and the rotating shaft 123 is connected with the rotating piece 130. By connecting the rotating shaft 123 with the rotating piece 130, that is, connecting the metal piece (alloy piece) with the metal piece (alloy piece), the installation reliability of the rotating shaft 123 can be ensured, so as to avoid the rotating shaft 123 from being separated from the band 110.

[0092] The materials of the clamping piece 120, the rotating shaft 123 and the rotating piece 130 can be stainless steel, copper, etc.; the material of the band 110 can be fluorine rubber, silicone, thermoplastic silicone rubber, etc. The connection mode of the rotating shaft 123 and the rotating piece 130 is not unique, the rotating shaft 123 can be rotatably connected with the rotating piece 130, and the clamping piece 120 is fixed in the circumferential direction; the rotating shaft 123 can also be fixedly connected with the rotating piece 130, and the through hole on the clamping piece 120 is rotatably matched with the rotating shaft 123.

[0093] In some embodiments, as shown in FIGS. 9 and 10, the adapter 130 includes two adapter arms 131 arranged along the width direction Y of the band 110, and an intermediate connecting arm 132 connected between the two adapter arms 131, the intermediate connecting arm 132 and the two adapter arms 131 integrally form a U-shaped structure, the shaft 123 is arranged between the two adapter arms 131, and the two ends of the shaft 123 are respectively connected with the two adapter arms 131. In this way, the two adapter arms 131 can limit the shaft 123, which can prevent the shaft 123 from being separated from the adapter 130, thereby improving the connection reliability of the shaft 123 and the adapter 130, and further improving the connection reliability of the shaft 123 and the band 110.

[0094] Of course, the number of the adapter arms 131 in the adapter 130 can also be one, the adapter arm 131 and the intermediate connecting arm 132 integrally form an L-shaped structure, and one end of the shaft 123 is connected with the adapter arm 131.

[0095] FIG. 11 is a top view of the wearable device in FIG. 1 after removing the fixing band 100 on one side, FIG. 12a is a C-C cross-sectional view of the wearable device in FIG. 11, FIG. 12b is a state diagram one of the wearable device in FIG. 1 in the disassembly process, FIG. 12c is a state diagram two of the wearable device in FIG. 1 in the disassembly process, FIG. 12d is a state diagram three of the wearable device in FIG. 1 in the disassembly process, and FIG. 12e is a state diagram of the fixing band 100 and the device main body 200 of the wearable device in FIG. 1 being separated.

[0096] As shown in FIGS. 11, 12a and 12b, the clamping piece 120 can move between a locked position (as shown in FIG. 12a) and an unlocked position (as shown in FIG. 12b).

[0097] As shown in FIG. 12a, when the clamping piece 120 is in the locked position, the clamping piece main body 121 extends into the first clamping groove 210 and abuts against the groove bottom wall 211, and the protruding part 122 extends into the second clamping groove 220, so that the fixing band 100 is clamped with the device main body 200; the protruding part 122 and the groove wall of the second clamping groove 220 have a clearance space 300 for avoiding the protruding part 122, so that the clamping piece 120 can move to the unlocked position.

[0098] It should be understood that, as shown in FIG. 12a, when the clamping piece 120 is located at the locking position, the second clamping groove 220 can limit the freedom of the clamping piece 120 in the direction X of the depth of the first clamping groove 210, and the side walls of the first clamping groove 210 (such as the first side wall 212 and the second side wall 213) can limit the freedom of the clamping piece 120 in the direction perpendicular to the direction X of the depth of the first clamping groove 210, so as to achieve the clamping of the fixing band 100 and the device main body 200, and avoid the separation of the fixing band 100 from the device main body 200 under the pulling of external force.

[0099] As shown in FIG. 12b, when the clamping piece 120 is located at the unlocking position, the second end portion 121b is located at the edge of the slot of the first clamping groove 210, and the clamping piece main body 121 can move out of the first clamping groove 210, so as to separate the fixing band 100 from the device main body 200.

[0100] The process of separating the fixing band 100 from the device main body 200 can be referred to FIGS. 12b-12e. As shown in FIG. 12b, when the clamping piece 120 is located at the unlocking position, since the second end portion 121b is located at the edge of the slot of the first clamping groove 210, the fixing band 100 can be pulled out of the first clamping groove 210 in the direction away from the first side wall 212 (such as the direction to the lower right in the figure), as shown in FIG. 12c, so as to move the second end portion 121b of the clamping piece main body 121 out of the first clamping groove 210, and the protruding portion 122 out of the second clamping groove 220; after the protruding portion 122 moves out of the second clamping groove 220, the fixing band 100 can be pulled in the direction away from the bottom wall 211 of the first clamping groove 210 (such as the direction to the right in the figure), as shown in FIGS. 12d and 12e, so as to gradually move the clamping piece 120 out of the first clamping groove 210, thereby achieving the separation of the fixing band 100 from the device main body 200.

[0101] The process of installing the fixing band 100 is opposite to the process of separation, which is as follows. As shown in FIG. 12e, the end of the fixing band 100 provided with the clamping piece 120 is close to the first clamping groove 210 of the device main body 200; as shown in FIGS. 12d and 12c, under the driving force of human force, elastic force, magnetic attraction and the like, the clamping piece 120 is rotated to the unlocking position, the protruding portion 122 is inserted into the first clamping groove 210 and opposite to the slot of the second clamping groove 220; as shown in FIGS. 12b and 12a, under the driving force of human force, magnetic attraction and the like, the clamping piece 120 moves towards the second clamping groove 220, so that the protruding portion 122 is inserted into the second clamping groove 220, and the clamping piece main body 121 is inserted into the first clamping groove 210 and abuts against the bottom wall 211, thereby achieving the clamping of the fixing band 100 and the device main body 200.

[0102] The wearable device in the embodiments of the present application can realize the clamping and separation of the fixing band 100 and the device main body 200 by rotating the clamping piece 120 between the locking position and the unlocking position, that is, the clamping piece 120 plays a clamping role and also plays an unlocking role, so that it is not necessary to additionally set an unlocking part that moves in cooperation with the clamping piece 120, thereby being beneficial to simplifying the detachable connection structure between the fixing band 100 and the device main body 200, and further being beneficial to improving the connection reliability between the fixing band 100 and the device main body 200.

[0103] In some embodiments, as shown in FIG. 12a, the clamping piece body 121 has an abutting face 1211 and a back face 1212 arranged opposite to the abutting face 1211, the abutting face 1211 and the back face 1212 are respectively connected between the first end 121a and the second end 121b, and the abutting face 1211 is used for abutting with the groove bottom wall 211.

[0104] As shown in FIG. 13, which is a partial enlarged view of the wearable device in FIG. 12a at the second clamping groove 220, the protruding part 122 includes a first side face 1221 arranged close to the abutting face 1211 and a second side face 1222 arranged away from the abutting face 1211. The avoiding space 300 includes a first gap 310 between the first side face 1221 and the groove wall of the second clamping groove 220. The first gap 310 is surrounded by the first side face 1221, the left groove side wall of the second clamping groove 220 and the groove top wall of the second clamping groove 220.

[0105] In the process of detaching the fixing band 100, that is, in the process of rotating the clamping piece 120 to the unlocking position, the top of the protruding part 122 gradually approaches the left groove side wall of the second clamping groove 220, and by arranging the first gap 310 between the first side face 1221 and the groove wall of the second clamping groove 220, the first gap 310 can avoid the movement of the protruding part 122, so as to avoid the movement interference between the protruding part 122 and the left groove side wall of the second clamping groove 220, thereby making the detaching process of the fixing band 100 more smooth.

[0106] In some embodiments, as shown in FIG. 13 and FIG. 14, FIG. 14 is a structural schematic diagram of the clasp 120 of the wearable device in FIG. 12a. The first side surface 1221 is obliquely arranged relative to the height direction H of the protruding portion 122, and the first side surface 1221 is obliquely arranged toward the side close to the second side surface 1222. In this way, the first gap 310 can be arranged to have a wider width closer to the top of the protruding portion 122, so that the first gap 310 has sufficient space to avoid the top of the protruding portion 122 during the rotation of the clasp 120 to the unlocking position, thereby avoiding the movement interference between the top of the protruding portion 122 and the left side wall of the second clamping groove 220, and making the disassembly process of the fixed strap 100 more smooth.

[0107] In some embodiments, as shown in FIG. 13 and FIG. 14, the oblique arrangement of the first side surface 1221 toward the side close to the second side surface 1222 is that the first side surface 1221 has a first side surface end 1221a arranged close to the clasp body 121, and a second side surface end 1221b arranged away from the clasp body 121, and the second side surface end 1221b deviates from the first side surface end 1221a toward the side close to the second side surface 1222.

[0108] Of course, the first side surface 1221 can also be arranged parallel to the height direction H of the protruding portion 122, so that the width of the first gap 310 along the length direction is constant, and the first gap 310 can also avoid the movement of the protruding portion 122 in this way.

[0109] In some embodiments, as shown in FIG. 13, FIG. 14 and FIG. 15, FIG. 15 is a structural schematic diagram of the clasp 120 shown in FIG. 14 from another perspective. The protruding portion 122 further includes a top surface 1223 connected between the first side surface 1221 and the second side surface 1222, and the avoidance space 300 includes a second gap 320 between the top surface 1223 and the groove wall of the second clamping groove 220 (i.e., the groove top wall of the second clamping groove 220).

[0110] During the disassembly of the fixed strap 100, that is, during the rotation of the clasp 120 to the unlocking position, the top of the protruding portion 122 (i.e., the top surface 1223) gradually approaches the groove top wall of the second clamping groove 220. By arranging the second gap 320 between the top surface 1223 and the groove top wall of the second clamping groove 220, the second gap 320 can avoid the movement interference between the protruding portion 122 and the groove top wall of the second clamping groove 220, thereby making the disassembly process of the fixed strap 100 more smooth.

[0111] In some embodiments, as shown in FIG. 13, the top surface 1223 is inclined relative to the height direction H of the protruding portion 122, so that the width of the second gap 320 gradually increases along the first direction X+.

[0112] As shown in FIG. 13, the top surface 1223 includes a first top surface end 1223a connected to the first side surface 1221, and a second top surface end 1223b connected to the second side surface 1222, the first top surface end 1223a is higher than the second top surface end 1223b relative to the protruding portion 122, that is, the first top surface end 1223a is higher than the second top surface end 1223b relative to the clamping member body 121, so that the width of the second gap 320 gradually increases along the first direction X+.

[0113] In the process of disassembling the fixing bandage 100, that is, in the process of rotating the clamping member 120 to the unlocking position, the top of the protruding portion 122 (that is, the top surface 1223) gradually approaches the slot top wall of the second clamping groove 220, the right corner of the top of the protruding portion 122 (the corner at the second top surface end 1223b) has a larger movement amplitude than the left corner of the top of the protruding portion 122 (the corner at the first top surface end 1223a), by setting the width of the second gap 320 gradually increasing along the first direction X+, that is, the wider the width of the second gap 320 is, the closer it is to the right corner of the top of the protruding portion 122, so that the second gap 320 has sufficient space to avoid the right corner of the top of the protruding portion 122, avoiding the movement interference between the right corner of the top of the protruding portion 122 and the slot top wall of the second clamping groove 220, thereby making the disassembly process of the fixing bandage 100 more smooth.

[0114] In order to prevent the protruding portion 122 from being pulled out of the second clamping groove 220, in some embodiments, as shown in FIG. 13, the inclination angle θ2 of the top surface 1223 relative to the height direction H of the protruding portion 122 is greater than the inclination angle θ1 of the first side surface 1221 relative to the height direction H of the protruding portion 122.

[0115] As shown in FIG. 13, the inclination angle θ2 of the top surface 1223 has a certain relationship with the width of the second side surface 1222 (that is, the size of the second side surface 1222 in the height direction H of the protruding portion 122), the greater the inclination angle θ2 of the top surface 1223, the greater the width of the second side surface 1222; the smaller the inclination angle θ2 of the top surface 1223, the smaller the width of the second side surface 1222.

[0116] By setting the inclination angle θ2 of the top surface 1223 to be greater than the inclination angle θ1 of the first side surface 1221, the inclination angle θ2 of the top surface 1223 can be made larger, so that the second side surface 1222 has a larger width, and the second side surface 1222 with a larger width can have a larger contact area with the right slot side wall of the second clamping groove 220, thereby better preventing the protruding portion 122 from being pulled out of the second clamping groove 220, and further ensuring the connection reliability between the fixed strap 100 and the device main body 200.

[0117] Of course, the top surface 1223 is perpendicular to the height direction H of the protruding portion 122, so that the second gap 320 has a constant width along the length direction thereof, and the second gap 320 is also arranged to avoid the movement of the protruding portion 122.

[0118] In order to avoid the movement interference between the corner of the clamping member body 121 and the first slot side wall 212 during the dismounting of the fixed strap 100, in some embodiments, as shown in FIGS. 13 and 15, a connecting surface 1213 is arranged between the back surface 1212 and the protruding portion 122, as shown in FIG. 13, when the clamping member 120 is in the locked position, the connecting surface 1213 and the first slot side wall 212 have an avoiding gap 400 therebetween.

[0119] During the dismounting of the fixed strap 100, that is, during the rotation of the clamping member 120 to the unlocked position, the first corner formed by the connecting surface 1213 and the back surface 1212 will gradually approach the first slot side wall 212. By arranging the avoiding gap 400 between the connecting surface 1213 and the first slot side wall 212, the avoiding gap 400 can avoid the movement of the first corner, thereby avoiding the movement interference between the first corner and the first slot side wall 212, and further making the dismounting process of the fixed strap 100 more smooth.

[0120] In order to better avoid the movement interference between the corner of the clamping member body 121 and the first slot side wall 212, in some embodiments, as shown in FIG. 13, the connecting surface 1213 is arranged to be inclined relative to the height direction H of the protruding portion 122, so that the width of the avoiding gap 400 gradually increases along the first direction X+. In this way, the wider the avoiding gap 400 is, the closer it is to the first corner. During the dismounting of the fixed strap 100, that is, during the rotation of the clamping member 120 to the unlocked position, the avoiding gap 400 has sufficient space to avoid the first corner, thereby better avoiding the movement interference between the first corner and the first slot side wall 212, and further making the dismounting process of the fixed strap 100 more smooth.

[0121] As shown in FIG. 13, the connecting surface 1213 includes a first connecting surface end 1213a arranged close to the protruding portion 122, and a second connecting surface end 1213b arranged away from the protruding portion 122, the second connecting surface end 1213b deviates from the first connecting surface end 1213a towards the direction close to the second end portion 121b, so that the width of the avoiding gap 400 gradually increases along the first direction X+.

[0122] In some embodiments, as shown in FIG. 13 and FIG. 15, a rounded corner 1214 is arranged between the back surface 1212 and the connecting surface 1213. By arranging the rounded corner 1214, the sharp corner formed between the back surface 1212 and the connecting surface 1213 can be removed, so that the corner formed between the back surface 1212 and the connecting surface 1213 does not scratch the band body 110 and the first groove sidewall 212 during the rotation of the clamping piece 120 around the rotation shaft 123, thereby reducing the probability of surface damage of the band body 110 and the first groove sidewall 212.

[0123] In order to facilitate the movement of the clamping piece body 121 to the unlocked position, as shown in FIG. 12a, the clamping piece 120 further includes a pressing portion 124, the pressing portion 124 is connected with the second end portion 121b of the clamping piece body 121, and the clamping piece 120 moves to the unlocked position when the pressing portion 124 is pressed.

[0124] As shown in FIG. 12a, the pressing portion 124 and the clamping piece body 121 can be an integral structure, but are not limited thereto, and the pressing portion 124 can also be arranged separately from the clamping piece body 121.

[0125] In some embodiments, as shown in FIG. 12a, an anti-slip structure 1242 is arranged on the pressing surface 1241 of the pressing portion 124. In this way, when the pressing portion 124 is pressed by the finger, the anti-slip structure 1242 can prevent the finger from slipping between the pressing surface 1241 of the pressing portion 124, thereby facilitating the pressing of the pressing portion 124.

[0126] The anti-slip structure 1242 is not unique, for example, as shown in FIG. 12a, the anti-slip structure 1242 can be an anti-slip groove, the extension direction of the anti-slip groove can be parallel to the rotation shaft 123, or can form a certain angle with the rotation shaft 123, which is not limited herein. For another example, the anti-slip structure 1242 can also be an anti-slip protrusion.

[0127] In the process of use, the band 110 will inevitably be pulled by external force. When pulled, the pulling force received by the band 110 will be transmitted to the clamping piece 120 through the rotating shaft 123. At this time, the clamping piece 120 has a tendency to move outwards of the first clamping groove 210. In order to avoid the clamping piece 120 from being separated from the first clamping groove 210 under the pulling of external force, in some embodiments, as shown in FIG. 12a, the rotating shaft 123 is arranged at the first end portion 121a of the clamping piece main body 121.

[0128] In this way, the position of the rotating shaft 123 is close to the protruding portion 122, that is, when the band 110 is pulled by external force, the stress point of the clamping piece 120 is located at the first end portion 121a (that is, the position of the rotating shaft 123). Since the freedom of the protruding portion 122 at the first end portion 121a is limited by the second clamping groove 220, the clamping piece main body 121 is not easy to be separated from the first clamping groove 210 when the band 110 is pulled by external force, thereby ensuring the connection reliability between the fixed band 100 and the device main body 200. In addition, the rotating shaft 123 is arranged at the first end portion 121a, which increases the length of the force arm of the pressing portion 124, thereby making the pressing portion 124 more labor-saving in the pressing process.

[0129] In some embodiments, as shown in FIG. 12a, the height of the second groove side wall 213 protruding from the groove bottom wall 211 is less than the height of the first groove side wall 212 protruding from the groove bottom wall 211. In this way, in the process of disassembling the fixed band 100, that is, in the process of rotating the clamping piece 120 to the unlocking position, the second end portion 121b of the clamping piece main body 121 can be conveniently moved out of the first clamping groove 210 at the second groove side wall 213, thereby making the disassembly process of the fixed band 100 more smooth.

[0130] In some embodiments, as shown in FIG. 12a and FIG. 16, FIG. 16 is a partial enlarged view of the wearable device at the second groove side wall 213 shown in FIG. 12a. The inner surface 2131 of the second groove side wall 213 is arranged to be inclined relative to the groove depth direction of the first clamping groove 210, and the inner surface 2131 of the second groove side wall 213 is arranged to be inclined to the side away from the first groove side wall 212. In this way, in the process of installing the fixed band 100 on the device main body 200, the inner surface 2131 of the second groove side wall 213 can play a guiding role on the clamping piece main body 121. As shown in FIG. 12b, when the second end portion 121b of the clamping piece main body 121 is located at the slot of the first clamping groove 210, the second end portion 121b of the clamping piece main body 121 can enter the first clamping groove 210 along the inner surface 2131 of the second groove side wall 213, as shown in FIG. 12a, thereby enabling the fixed band 100 to be clamped with the device main body 200.

[0131] As shown in FIG. 12a and FIG. 16, the inner surface 2131 of the second slot side wall 213 is inclined to the side away from the first slot side wall 212, that is, the lower side in the drawing. Specifically, the inner surface 2131 of the second slot side wall 213 includes a proximal end 2131a disposed close to the slot bottom wall 211, and a distal end 2131b disposed away from the slot bottom wall 211, the distal end 2131b deviates from the proximal end 2131a to the side away from the first slot side wall 212, that is, the lower side in the drawing.

[0132] In some embodiments, as shown in FIG. 12a, the wearable device further includes a magnetic attraction component 500 disposed on at least one of the device main body 200 and the clasp main body 121 (the magnetic attraction component 500 is disposed on the device main body 200 and the clasp main body 121 in the drawing), the magnetic attraction component 500 is used to apply a magnetic attraction force to the clasp main body 121, and the magnetic attraction force can cause the clasp main body 121 to move towards the slot bottom wall 211. In this way, the magnetic attraction component 500 can play a role in magnetic attraction positioning of the clasp main body 121 of the fixing band 100 during the installation of the fixing band 100, thereby facilitating the installation of the clasp main body 121 into the first slot 210.

[0133] In some embodiments, as shown in FIG. 12a, the magnetic attraction component 500 includes a first magnetic attraction piece 510 and a second magnetic attraction piece 520, the first magnetic attraction piece 510 is disposed at a position corresponding to the slot bottom wall 211 of the device main body 200, and the second magnetic attraction piece 520 is disposed on the clasp main body 121 and on the side of the pivot shaft 123 close to the second end 121b of the clasp main body 121, and the first magnetic attraction piece 510 and the second magnetic attraction piece 520 can generate a magnetic attraction force therebetween. The first magnetic attraction piece 510 and the second magnetic attraction piece 520 can each be a magnet.

[0134] Because the first magnetic attraction piece 510 and the second magnetic attraction piece 520 have a magnetic attraction positioning function, when the clasp main body 121 approaches the device main body 200, the end of the fixing band 100 provided with the clasp 120 can be automatically attracted and clamped to the device main body 200 under the action of the magnetic attraction force of the first magnetic attraction piece 510 and the second magnetic attraction piece 520, without the need for manual operation during the attraction of the fixing band 100, thereby greatly facilitating the installation of the fixing band 100.

[0135] The process of the fixing band 100 being automatically attracted and clamped to the device main body 200 under the action of the magnetic attraction force will be described in detail below.

[0136] As shown in FIG. 12e, first, the fixing band 100 sets one end of the clamping piece 120 close to the first clamping slot 210 of the device main body 200. As shown in FIG. 12c, under the action of the magnetic attraction force between the first magnetic attraction piece 510 and the second magnetic attraction piece 520, the clamping piece 120 moves towards the direction close to the slot bottom wall 211 of the first clamping slot 210, the abutting surface 1211 of the clamping piece 120 abuts against the second slot side wall 213, and at the same time, the first end 121a of the clamping piece 120 extends into the first clamping slot 210 and abuts against the slot bottom wall 211. At this time, the clamping piece 120 is located at the unlocking position, and the protruding part 122 is opposite to the slot opening of the second clamping slot 220. As shown in FIG. 12c and FIG. 12b, since the first magnetic attraction piece 510 and the second magnetic attraction piece 520 have magnetic attraction positioning property, at this time, the clamping piece main body 121 is subjected to the magnetic attraction force towards the upper left, and under the action of the magnetic attraction force, the clamping piece main body 121 moves upwards so that the second end 121b of the clamping piece main body 121 is located at the slot opening of the first clamping slot 210. Since the inner surface 2131 of the second slot side wall 213 is inclined relative to the slot depth direction of the first clamping slot 210, under the action of the magnetic attraction force, as shown in FIG. 12b and FIG. 12a, the second end 121b of the clamping piece main body 121 enters the first clamping slot 210 along the inner surface 2131 of the second slot side wall 213, so that the abutting surface 1211 of the clamping piece 120 abuts against the slot bottom wall 211, and the protruding part 122 extends into the second clamping slot 220, thereby realizing the clamping between the fixing band 100 and the device main body 200.

[0137] In some embodiments, as shown in FIG. 5, the device main body 200 is provided with a first containing slot 231 at the position corresponding to the slot bottom wall 211, the first magnetic attraction piece 510 is arranged in the first containing slot 231, and the first containing slot 231 is provided with a first protective cover plate 232 at the slot opening, which covers the first magnetic attraction piece 510. In this way, the first protective cover plate 232 can protect the first magnetic attraction piece 510 in the first containing slot 231 from being damaged by contacting other components.

[0138] As shown in FIG. 5 and FIG. 6, the first containing slot 231 is arranged on the shell 250 of the device main body 200. Further, the first containing slot 231 is arranged on the middle frame 251.

[0139] In some embodiments, as shown in FIG. 8, the clamping member body 121 is provided with a second accommodating groove 1215, and the second magnetic attraction member 520 is arranged in the second accommodating groove 1215. The second accommodating groove 1215 is provided with a second protective cover plate 1216 at the groove opening, and the second protective cover plate 1216 covers the second magnetic attraction member 520. In this way, the second protective cover plate 1216 can protect the second magnetic attraction member 520 in the second accommodating groove 1215 from being damaged by contacting other components.

[0140] As shown in FIG. 8, the second accommodating groove 1215 is arranged on the back surface 1212 of the clamping member body 121, so as to avoid arranging the second accommodating groove 1215 on the abutting surface 1211.

In this way, the first magnetic attraction member 510 and the clamping member 120 can also generate a magnetic attraction force.

[0142] In the wearable device in the embodiments of the present application, the magnetic attraction member 500 can also be replaced by an elastic member. The elastic member is connected to the clamping member 120, and the elastic member is used to apply an elastic force to the clamping member 120 to move to the locking position. In this way, under the action of the elastic force, the clamping member 120 can be kept in abutment with the groove bottom wall 211 of the first clamping groove 210, thereby facilitating to improve the connection reliability between the fixing band 100 and the device body 200.

[0143] The specific type of the elastic member is not unique. For example, the elastic member can be a spring. The spring is connected between the groove wall of the clamping member accommodating groove 114 and the pressing portion 124 of the clamping member 120. When the clamping member 120 is in the unlocking position, the spring is in a compressed state. For another example, the elastic member can also be a torsion spring. The torsion spring is sleeved on the rotating shaft 123. One connecting arm of the torsion spring is in abutment with the groove wall of the clamping member accommodating groove 114, and the other connecting arm of the torsion spring is in abutment with the clamping member body 121. When the clamping member 120 is in the unlocking position, the torsion spring is in a force storage state.
