Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a wearable device, a fixing strap thereof, and a device body. Background Art

[0002] Wearable devices are portable electronic devices 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, and smart glasses. Wearable devices offer diverse functions, convenient operation and interaction, stylish appearance and design, long battery life, and durability, providing users with a smarter, more convenient, and healthier lifestyle.

[0003] Wearable devices primarily consist of a device body and a strap. The strap is used to secure the device to the wearer's body and features a detachable connection to the device body, facilitating its replacement. Designing the detachable connection between the strap and the device body directly impacts assembly and disassembly efficiency, and has become a key industry challenge. Utility Model Content

[0004] The embodiments of the present application provide a wearable device, a fixing strap thereof, and a device body, which are used to solve the problem of a relatively complex detachable connection structure between the fixing strap and the device body of the wearable device in the related art.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a wearable device, comprising a device body and a fixing strap detachably connected to the device body; a first card slot is provided on the device body, the first card slot having a slot bottom wall, and first and second slot side walls respectively arranged at opposite side edges of the slot bottom wall, and a second card slot is provided on the first slot side wall; the fixing strap comprises a belt body, and a clip arranged at one end of the belt body, the clip comprising a clip body and a protrusion, the clip body having opposite first and second ends, the protrusion being arranged at the first end and protruding from the clip body in a direction away from the second end ; The main body of the clip is rotatably connected to the belt body through a rotating shaft, so that the clip can move between a locked position and an unlocked position; when the clip is in the locked position, the main body of the clip extends into the first slot and abuts against the bottom wall of the slot, and the protrusion extends into the second slot, so that the fixing strap is clamped to the device body; there is an avoidance space between the protrusion and the slot wall of the second slot, and the avoidance space is used to avoid the protrusion, so that the clip can move to the unlocked position; when the clip is in the unlocked position, the second end is located at the edge of the slot of the first slot, and the main body of the clip can be moved out of the first slot to separate the fixing strap from the device body.

[0007] The wearable device in the embodiment of the present application can realize the connection and separation of the fixed strap and the device body by rotating the snap-on member between the locking position and the unlocking position. That is, the snap-on member plays both the function of connection and the function of unlocking. In this way, there is no need to additionally set up an unlocking component that cooperates with the movement of the snap-on member, which is conducive to simplifying the detachable connection structure between the fixed strap and the device body, and further helps to improve the connection reliability between the fixed strap and the device body.

[0008] In some embodiments of the first aspect, the clamping member body includes an abutting surface configured to abut against the bottom wall of the slot, the raised portion includes a first side surface disposed proximate to the abutting surface, and a second side surface disposed distal to the abutting surface, and the clearance space includes a first gap located between the first side surface and the slot wall of the second clamping slot. This configuration prevents motion interference between the raised portion and the side wall of the second clamping slot.

[0009] In some embodiments of the first aspect, the first side surface is inclined relative to the height direction of the protrusion, and the first side surface is inclined toward a side closer to the second side surface. Specifically, the first side surface is inclined toward a side closer to the second side surface by: the first side surface has a first side surface end located closer to the main body of the connector, and a second side surface end located farther away from the main body of the connector, with the second side surface end deviating from the first side surface end toward a side closer to the second side surface. This arrangement can better prevent motion interference between the top of the protrusion and the sidewalls of the second slot.

[0010] In some embodiments of the first aspect, the raised portion further includes a top surface connected between the first side surface and the second side surface, and the avoidance space includes a second gap located between the top surface and a wall of the second slot. This arrangement can prevent motion interference between the raised portion and the top wall of the second slot.

[0011] In some embodiments of the first aspect, the top surface is inclined relative to the height direction of the protrusion, so that the width of the second gap gradually increases along a first direction; the first direction is parallel to the depth of the first slot and extends from the bottom wall of the slot to the slot opening of the first slot. This configuration can prevent the corner of the top of the protrusion from interfering with the top wall of the second slot.

[0012] In some embodiments of the first aspect, an inclination angle of the top surface relative to the height direction of the protrusion is greater than an inclination angle of the first side surface relative to the height direction of the protrusion. This arrangement can better prevent the protrusion from falling out of the second slot.

[0013] In some embodiments of the first aspect, the clip body has an abutting surface and a back surface opposite the abutting surface, the abutting surface being configured to abut against the bottom wall of the groove; a connecting surface is provided between the back surface and the raised portion, and when the clip is in the locked position, a clearance is provided between the connecting surface and the sidewall of the first groove. This arrangement prevents movement interference between the corner of the clip body and the sidewall of the first groove during detachment of the fixing strap.

[0014] In some embodiments of the first aspect, the connecting surface is inclined relative to the height direction of the protrusion so that the width of the clearance gradually increases along a first direction; the first direction is parallel to the depth of the first slot and extends from the bottom wall of the slot to the slot opening of the first slot. This arrangement can better prevent movement interference between the corners of the connector body and the sidewalls of the first slot.

[0015] In some embodiments of the first aspect, a rounded corner is provided between the back surface and the connecting surface, so as to prevent the corner formed between the back surface and the connecting surface from scraping the belt body and the sidewall of the first groove during the rotation of the clamping member around the rotation axis.

[0016] In some embodiments of the first aspect, the height of the second groove sidewall protruding from the groove bottom wall is less than the height of the first groove sidewall protruding from the groove bottom wall. This configuration facilitates the second end portion b of the clip body to be removed from the first clip groove at the second groove sidewall during detachment of the fixing strap.

[0017] In some embodiments of the first aspect, the inner surface of the second groove sidewall is inclined relative to the groove depth direction of the first slot, and the inner surface of the second groove sidewall is inclined toward a side away from the first groove sidewall. Specifically, the inner surface of the second groove sidewall is inclined toward a side away from the first groove sidewall. The inner surface of the second groove sidewall includes a near end disposed near the groove bottom wall and a far end disposed away from the groove bottom wall, and the far end deviates from the near end toward a side away from the first groove sidewall. With this arrangement, the inner surface of the second groove sidewall can guide the main body of the clip when the fixing strap is installed on the device body.

[0018] In some embodiments of the first aspect, the wearable device further comprises a magnetic component disposed on at least one of the device body and the clip body, the magnetic component being configured to apply a magnetic force to the clip body, thereby causing the clip body to move toward the bottom wall of the slot.

This arrangement can facilitate movement of the clip body toward the unlocked position.

[0023] In some embodiments of the first aspect, the rotating shaft is disposed at the first end of the clip body. This arrangement prevents the clip body from easily falling out of the first slot when the belt body is pulled by an external force, and also allows the pressing portion to save effort during the pressing process.

[0024] In some embodiments of the first aspect, the pressing surface of the pressing portion is provided with an anti-slip structure, which can prevent the finger from sliding against the pressing surface of the pressing portion.

With this arrangement, the two adapter arms can limit the rotating shaft, preventing the rotating shaft from separating from the adapter, thereby facilitating improved connection reliability between the rotating shaft and the adapter.

[0027] In some embodiments of the first aspect, the strap body includes a first strap surface and a second strap surface disposed opposite each other, and a strap end surface connected between the first and second strap surfaces. The first strap surface serves as the exterior surface of the strap body, and the second strap surface is provided with a clip-on receiving groove extending through the strap end surface. The clip-on receiving groove extends through the strap end surface, and at least a portion of the clip is disposed within the clip-on receiving groove. The protrusion extends from the clip-on receiving groove and projects beyond the strap end surface. This arrangement can reduce the space occupied by the clip-on outside the strap body, thereby making the fixed strap structure more compact.

[0028] In the second aspect, an embodiment of the present application provides a fixing strap for detachably connecting to a device body of a wearable device, comprising a strap body and a clip arranged at one end of the strap body; the clip comprises a clip body, a protrusion and a pressing portion; the clip body has a first end and a second end relative to each other, and a contact surface connected between the first end and the second end, the contact surface being used to contact with the device body; the protrusion is arranged at the first end and protrudes from the clip body in a direction away from the second end; the protrusion comprises a first side surface arranged close to the contact surface, and a second side surface arranged away from the contact surface, the first side surface being inclined relative to the height direction of the protrusion, and the first side surface being inclined toward a side close to the second side surface; the pressing portion is connected to the second end, and the clip body is rotatably connected to the strap body through a rotating shaft so that the clip can move between a locked position and an unlocked position; when the pressing portion is pressed, the clip moves to the unlocked position.

[0029] Specifically, the first side surface is inclined toward the side close to the second side surface, and the first side surface has a first side surface end close to the main body of the clamp, and a second side surface end away from the main body of the clamp, and the second side surface end deviates from the first side surface end toward the side close to the second side surface.

[0030] The beneficial effects of the fixing strap in the embodiment of the present application are the same as the beneficial effects of the wearable device in the first aspect, and will not be repeated here.

[0031] In some embodiments of the second aspect, the raised portion further includes a top surface connected between the first side surface and the second side surface, the top surface being inclined relative to the height direction of the raised portion; the top surface includes a first top surface end connected to the first side surface, and a second top surface end connected to the second side surface, the first top surface end tilting relative to the second top surface end in a direction away from the clip body. This arrangement can prevent the corner of the top of the raised portion from interfering with the top wall of the second slot.

[0032] In some embodiments of the second aspect, the inclination angle of the top surface relative to the height direction of the protrusion is greater than the inclination angle of the first side surface relative to the height direction of the protrusion. This arrangement can better prevent the protrusion from falling out of the second slot.

[0033] In some embodiments of the second aspect, the clip body further includes a back surface disposed opposite the abutting surface, a connecting surface disposed between the back surface and the raised portion, the connecting surface being inclined relative to the height direction of the raised portion; the connecting surface includes a first connecting surface end disposed proximal to the raised portion, and a second connecting surface end disposed distal to the raised portion, the second connecting surface end deviating from the first connecting surface end toward the second end portion.

[0035] In some embodiments of the second aspect, a second magnetic member is provided on the main body of the clip, and the second magnetic member is disposed on a side of the rotating shaft near the second end. This arrangement allows the second magnetic member on the main body of the clip to attract the first magnetic member on the main body of the device, thereby magnetically positioning the main body of the clip. Furthermore, one end of the clip provided on the fixing strap can automatically attract and engage with the main body of the device, eliminating the need for manual engagement of the fixing strap.

[0036] In some embodiments of the second aspect, a second receiving slot is provided on the main body of the clip, the second magnetic member is disposed in the second receiving slot, and a second protective cover is provided at the notch of the second receiving slot, the second protective cover covering the second magnetic member. Thus, the second protective cover can protect the second magnetic member in the second receiving slot.

[0037] In some embodiments of the second aspect, the rotating shaft is disposed at the first end of the clip body.

[0066] The technical solutions in some embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0067] Wearable devices are portable electronic devices 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, and smart glasses. Wearable devices offer diverse functions, convenient operation and interaction, stylish appearance and design, long battery life, and durability, providing users with a smarter, more convenient, and healthier lifestyle.

[0068] Wearable devices primarily consist of a device body and a strap. The strap is used to secure the device to the wearer's body and features a detachable connection to the device body, facilitating its replacement. Designing the detachable connection between the strap and the device body directly impacts assembly and disassembly efficiency, and has become a key industry challenge.

[0069] In a wearable device in the related art, a fixing strap is connected to the device body via a spring ear. When removing the fixing strap, a tool is required, which makes the removal and assembly of the fixing strap inconvenient.

[0070] In order to facilitate the disassembly and assembly of the fixing strap, another wearable device in the related art is connected to the device body through a clip-on structure with an unlocking button. When the fixing strap is installed on the device body, the device body is clipped to the fixing strap through a clip, and the unlocking button limits the movement of the clip to lock the clip; when the fixing strap needs to be removed, the unlocking button is pressed, and the unlocking button releases the movement lock on the clip, and the clip can be detached from the fixing strap, thereby realizing the detachment of the fixing strap from the device body.

[0071] However, in the wearable device of the related art, the fixed strap and the device body are connected and unlocked by a snap-on part and an unlocking button. The unlocking button and the snap-on part need to move together, which not only increases the number of parts, but also makes the detachable connection structure between the fixed strap and the device body more complicated, which is not conducive to improving the connection reliability.

[0072] To this end, an embodiment of the present application provides a wearable device, a fixing strap, and a device body thereof. A snap-fitting piece is provided on the strap body of the fixing strap, and snapping and unlocking are achieved by rotating the snap-fitting piece to different positions. In this way, there is no need to additionally provide an unlocking component that cooperates with the movement of the snap-fitting piece, thereby simplifying the detachable connection structure between the fixing strap and the device body, and thus helping to improve the connection reliability between the fixing strap and the device body.

[0073] The wearable device in the embodiment of the present application can be an electronic device that can be worn on the body, such as a smart watch, a smart bracelet, or smart glasses. The following takes a smart watch as an example to specifically introduce the detachable connection structure between the fixed strap and the device body. Other types of wearable devices can be specifically set with reference to the detachable connection structure in the smart watch embodiment, and will not be described in detail here.

[0074] Figure 1 This is a schematic diagram of the structure of a wearable device (smart watch) in some embodiments of the present application. Figure 2 for Figure 1 The structural diagram of the wearable device in another perspective, Figure 3 for Figure 1 Exploded diagram of the wearable device in . Figure 1 、 Figure 2 and Figure 3 As shown, the wearable device includes a device body 200 and a fixing strap 100 detachably connected to the device body 200 .

[0075] Among them, there are two fixing straps 100, namely fixing strap 100a and fixing strap 100b, one end of fixing strap 100a and fixing strap 100b are detachably connected to opposite sides of device body 200, and fixing strap 100a and fixing strap 100b can be connected together by a locking structure, so that fixing strap 100a, fixing strap 100b and device body 200 form a ring structure, which can be put on the human body (such as the wrist), thereby realizing that the wearable device is worn on the human body. It should be noted that fixing strap 100a and fixing strap 100b can also adopt other connection methods besides the locking structure, which is not limited in the embodiment of the present application.

[0076] Figure 4 for Figure 1 A schematic structural diagram of a device body 200 of a wearable device, Figure 5 for Figure 4 AA section view of the device body in FIG. Figure 4 and Figure 5 As shown, a first card slot 210 is provided on the device body 200, and the first card slot 210 has a slot bottom wall 211, and a first slot side wall 212 and a second slot side wall 213 respectively arranged at the opposite side edges of the slot bottom wall 211, and a second card slot 220 is provided on the first slot side wall 212.

[0077] The bottom wall 211 is the wall of the first slot 210 that is opposite to the slot opening; Figure 5 As shown, the second card slot 220 can be set at a position of the first slot side wall 212 close to the slot bottom wall 211 of the first slot 210, that is, one side slot side wall of the second card slot 220 is flush with the slot bottom wall 211 of the first slot 210; but it is not limited to this, the second card slot 220 can be set at other positions of the first slot side wall 212.

[0078] The device body 200 is the core of the wearable device, used to implement specific functions such as health monitoring, activity tracking, and notification reminders. The device body 200 includes a housing 250 and a cover 240. The housing 250 has an opening on one side, and the cover 240 is mounted on the inside of the housing 250. Functional components such as the display, circuit board, and battery are mounted on the inside of the cover 240.

[0079] Among them, Figure 4 and Figure 5As shown, there are two first slots 210, each disposed on two opposing side walls of the housing 250. Each first slot 210 engages with a corresponding fixing strap 200. Along the thickness direction H of the device body 200, a first slot sidewall 212 of the first slot 210 is disposed on a side of the first slot 210 closer to the cover plate 240, and a second slot sidewall 213 is disposed on a side of the first slot 210 farther from the cover plate 240.

[0080] like Figure 5 and Figure 6 As shown, Figure 6 for Figure 4 The exploded view of the device body 200 is shown. The housing 250 includes a middle frame 251 and a back cover 252. The middle frame 251 is a metal or alloy part, and the back cover 252 is a plastic part. The middle frame 251 is arranged between the cover plate 240 and the back cover 252.

[0081] In order to reduce the deformation of the back cover 252 under the action of external force, in some embodiments, such as Figure 5 and Figure 6 As shown, the edge of the back cover 252 has a notch 2521, and the middle frame 251 is integrally provided with a flange 2511, which fits into the notch 2521. Since the flange 2511 is a metal or alloy part, the hardness of the flange 2511 is greater than that of the back cover 252. By extending the flange 2511 into the notch 2521, the flange 2511 can support and reinforce the back cover 252, thereby helping to reduce deformation of the back cover 252 under the action of external forces.

[0082] Among them, Figure 6 As shown, the second slot sidewall 213 is disposed on the flange 2511 , and the middle frame 251 and the back cover 252 form the first slot 210 .

[0083] Of course, the device body 200 is not limited to the above structure, and the device body 200 can also be specifically configured into other structures according to the type of wearable device. For example, the housing 250 can include a cover plate 240 and a back cover 252, and can include no middle frame 251.

[0084] Figure 7 for Figure 1 A partial view of a fixing strap 100 for a wearable device, Figure 8 for Figure 7 BB cross-sectional view of the fixing strap 100, Figure 9 for Figure 7 Exploded view of the fixing strap 110. Figure 7 and Figure 8As shown, the fixing strap 100 includes a belt body 110 and a clip 120 provided at one end of the belt body 110. The clip 120 includes a clip body 121 and a protrusion 122. The clip body 121 has a first end 121a and a second end 121b opposite to each other. The protrusion 122 is provided at the first end 121a and extends in a direction away from the second end 121b (i.e., Figure 8 The clip body 121 is rotatably connected to the belt body 110 via a rotating shaft 123.

[0085] Among them, Figure 7 and Figure 8 As shown, the protrusion 122 and the clamp body 121 are an integral structure, but it is not limited thereto. The protrusion 122 and the clamp body 121 can also be set separately, and the protrusion 122 is fixed on the clamp body 121. It is understandable that Figure 8 The middle up-down direction can be understood as the height direction H of the protrusion 122 .

[0086] In some embodiments, as Figure 7 、 Figure 8 and Figure 9 As shown, the belt body 110 includes a first belt surface 111 and a second belt surface 112 arranged opposite to each other, and a belt end surface 113 connected between the first belt surface 111 and the second belt surface 112. The first belt surface 111 is the appearance surface of the belt body 110, and the second belt surface 112 is provided with a clip receiving groove 114. The clip receiving groove 114 passes through the belt end surface 113. At least a portion of the clip 120 is arranged in the clip receiving groove 114, and the protrusion 122 extends from the clip receiving groove 114 and protrudes from the belt end surface 113.

[0087] By arranging at least a portion of the clip 120 in the clip accommodating groove 114, the space occupied by the clip 120 outside the belt body 110 can be reduced, thereby making the structure of the fixing strap 100 more compact; at the same time, the clip accommodating groove 114 can protect the clip 120 and reduce damage to the surface of the clip 120 by other external objects.

[0088] Among them, Figure 9 As shown, the clip body 121 can be rotatably connected to the slot side wall of the clip receiving slot 114 via the rotating shaft 123 .

[0089] Of course, the end of the belt body 110 may not be provided with the clip receiving groove 114 . The belt body 110 may be partially thinned at the end to form a thinned section, and the clip 120 may be provided inside the thinned section of the belt body 110 .

[0090] In some embodiments, as Figure 9 and Figure 10 As shown, Figure 10 for Figure 7 Schematic diagram of the installation of the shaft 123 of the fixed strap 100. An adapter 130 is embedded within the strap body 110. The clip 120, shaft 123, and adapter 130 are all made of metal or alloy. The strap body 110 is made of plastic, and the shaft 123 is connected to the adapter 130. Connecting the shaft 123 to the adapter 130—that is, connecting metal (alloy) to metal (alloy)—ensures the secure installation of the shaft 123, preventing it from separating from the strap body 110.

[0091] The materials for the connector 120, the rotating shaft 123, and the adapter 130 can be stainless steel, copper, etc.; the material for the belt body 110 can be fluororubber, silicone rubber, thermoplastic silicone rubber, etc. The connection between the rotating shaft 123 and the adapter 130 is not limited to a single method. The rotating shaft 123 can be rotatably connected to the adapter 130, with the connector 120 and the rotating shaft 123 fixed in the circumferential direction. Alternatively, the rotating shaft 123 can be fixedly connected to the adapter 130, with the through hole in the connector 120 rotatably engaging with the rotating shaft 123.

[0092] In some embodiments, as Figure 9 and Figure 10 As shown, the adapter 130 includes two adapter arms 131 spaced apart along the width direction Y of the belt body 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 form a U-shaped structure as a whole. The rotating shaft 123 is disposed between the two adapter arms 131, and the two ends of the rotating shaft 123 are respectively connected to the two adapter arms 131. This arrangement allows the two adapter arms 131 to limit the rotating shaft 123, preventing the rotating shaft 123 from separating from the adapter 130, thereby improving the connection reliability between the rotating shaft 123 and the adapter 130, and further improving the connection reliability between the rotating shaft 123 and the belt body 110.

[0093] Of course, the number of the adapter arm 131 in the adapter 130 may also be one. The adapter arm 131 and the middle connecting arm 132 form an L-shaped structure as a whole, and one end of the rotating shaft 123 is connected to the adapter arm 131 .

[0094] Figure 11 for Figure 1 A top view of the wearable device with one side of the fixing strap 100 removed, Figure 12a for Figure 11 CC cross-sectional view of the wearable device in Figure 12b for Figure 1 The status of the wearable device during the disassembly process Figure 1 , Figure 12c for Figure 1The status of the wearable device during the disassembly process Figure 2 , Figure 12d for Figure 1 The status of the wearable device during the disassembly process Figure 3 , Figure 12e for Figure 1 FIG2 is a diagram showing a state in which the fixing strap 100 of the wearable device is detached from the device body 200.

[0095] like Figure 11 、 Figure 12a as well as Figure 12b As shown, the latch 120 can be in the locked position (eg Figure 12a as shown) and unlocked position (as shown) Figure 12b shown).

[0096] like Figure 12a As shown, when the clamping member 120 is in the locked position, the clamping member body 121 extends into the first clamping slot 210 and abuts against the bottom wall 211 of the slot, and the protrusion 122 extends into the second clamping slot 220 to clamp the fixing strap 100 to the device body 200; there is an avoidance space 300 between the protrusion 122 and the slot wall of the second clamping slot 220, and the avoidance space 300 is used to avoid the protrusion 122 so that the clamping member 120 can move to the unlocking position.

[0097] Among them, it is necessary to understand that: Figure 12a As shown, when the clamping member 120 is in the locked position, the second clamping slot 220 can limit the freedom of the clamping member 120 in the groove depth direction X along the first clamping slot 210, and the groove side walls of the first clamping slot 210 (such as the first groove side wall 212 and the second groove side wall 213) can limit the freedom of the clamping member 120 in the groove depth direction X perpendicular to the first clamping slot 210, thereby realizing the clamping connection between the fixing strap 100 and the device body 200, and preventing the fixing strap 100 from being separated from the device body 200 under the pulling of external force.

[0098] like Figure 12b As shown, when the clip 120 is in the unlocked position, the second end 121b is located at the edge of the slot of the first slot 210, and the clip body 121 can be moved out of the first slot 210 to separate the fixing strap 100 from the device body 200.

[0099] The process of separating the fixing strap 100 from the device body 200 can be referred to Figure 12b to Figure 12e As shown, Figure 12b As shown, when the clip 120 is in the unlocked position, since the second end 121b is located at the edge of the slot of the first slot 210, the fixing strap 100 is pulled out of the first slot 210 (for example, in the lower right direction in the figure) by moving away from the first slot side wall 212. Figure 12cAs shown, the second end portion 121b of the clip body 121 can be moved out of the first slot 210, and the protrusion 122 can be moved out of the second slot 220. After the protrusion 122 is moved out of the second slot 220, the fixing strap 100 can be pulled in a direction away from the bottom wall 211 of the first slot 210 (for example, to the right in the figure), as shown. Figure 12d and Figure 12e As shown, the clamping member 120 can be gradually moved out of the first clamping slot 210 as a whole, thereby separating the fixing strap 100 from the device body 200.

[0100] The installation process of the fixing strap 100 is the opposite of the separation process, as follows: Figure 12e As shown, the end of the fixing strap 100 provided with the snap-fitting member 120 is brought close to the first snap-fitting slot 210 of the device body 200; Figure 12d and Figure 12c As shown, under the action of a driving force such as human power, elastic force, magnetic force, etc., the clip 120 is rotated to the unlocked position, and the protrusion 122 extends into the first slot 210 and faces the notch of the second slot 220; Figure 12b and Figure 12a As shown, under the action of driving forces such as human power and magnetic attraction, the clamping member 120 moves toward the direction close to the second clamping slot 220, so that the protrusion 122 extends into the second clamping slot 220, and the clamping member body 121 extends into the first clamping slot 210 and abuts against the bottom wall 211 of the slot, thereby realizing the clamping of the fixing strap 100 with the device body 200.

[0101] The wearable device in the embodiment of the present application can realize the connection and separation of the fixing strap 100 and the device body 200 by rotating the snap connector 120 between the locking position and the unlocking position, that is, the snap connector 120 plays both the role of clamping and the role of unlocking. In this way, there is no need to additionally set up an unlocking component that cooperates with the movement of the snap connector 120, which is conducive to simplifying the detachable connection structure between the fixing strap 100 and the device body 200, and further conducive to improving the connection reliability between the fixing strap 100 and the device body 200.

[0102] In some embodiments, as Figure 12a As shown, the clamp body 121 has a contact surface 1211 and a back surface 1212 arranged opposite to the contact surface 1211. The contact surface 1211 and the back surface 1212 are respectively connected between the first end 121a and the second end 121b. The contact surface 1211 is used to contact the groove bottom wall 211.

[0103] like Figure 13 As shown, Figure 13 for Figure 12aA partial enlarged view of the wearable device at the second slot 220. The raised portion 122 includes a first side surface 1221 disposed proximate to the abutting surface 1211, and a second side surface 1222 disposed distal to the abutting surface 1211. The escape space 300 includes a first gap 310 located between the first side surface 1221 and the wall of the second slot 220. The first gap 310 is formed by the first side surface 1221, the left sidewall of the second slot 220, and the top wall of the second slot 220.

[0104] During the process of detaching the fixing strap 100, that is, during the process of rotating the clip 120 to the unlocked position, the top of the protrusion 122 will gradually approach the left side wall of the second slot 220. By setting a first gap 310 between the first side surface 1221 and the slot wall of the second slot 220, the first gap 310 can avoid the movement of the protrusion 122, thereby avoiding movement interference between the protrusion 122 and the left side wall of the second slot 220, thereby making the detachment process of the fixing strap 100 smoother.

[0105] In some embodiments, as Figure 13 and Figure 14 As shown, Figure 14 for Figure 12a Schematic diagram of the structure of the clip 120 of the wearable device. The first side surface 1221 is tilted relative to the height direction H of the protrusion 122, and the first side surface 1221 is tilted toward the side close to the second side surface 1222. In this way, the first gap 310 becomes wider as it approaches the top of the protrusion 122. In this way, when the clip 120 rotates toward the unlocked position, the first gap 310 has sufficient space to avoid the top of the protrusion 122, avoiding movement interference between the top of the protrusion 122 and the left side wall of the second slot 220, thereby making the detachment process of the fixing strap 100 smoother.

[0106] Among them, Figure 13 and Figure 14 As shown, the first side surface 1221 is tilted toward the side close to the second side surface 1222. Specifically, the first side surface 1221 has a first side surface end 1221a arranged close to the clip body 121, and a second side surface end 1221b arranged away from the clip 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.

[0107] Of course, the first side surface 1221 can also be arranged parallel to the height direction H of the protrusion 122, so that the width of the first gap 310 along its length direction is constant. Setting the first gap 310 in this way can also avoid the movement of the protrusion 122.

[0108] In some embodiments, as Figure 13 、 Figure 14 and Figure 15 As shown, Figure 15 for Figure 14 , which is a schematic structural diagram of the clamping member 120 from another perspective. The raised portion 122 further includes a top surface 1223 connected between the first side surface 1221 and the second side surface 1222. The avoidance space 300 includes a second gap 320 located between the top surface 1223 and the groove wall of the second clamping slot 220 (i.e., the groove top wall of the second clamping slot 220).

[0109] During the process of detaching the fixing strap 100, that is, during the process of rotating the clip 120 to the unlocked position, the top of the protrusion 122 (that is, the top surface 1223) will gradually approach the top wall of the second slot 220. By setting a second gap 320 between the top surface 1223 and the top wall of the second slot 220, the second gap 320 can avoid the movement of the protrusion 122, thereby avoiding movement interference between the protrusion 122 and the top wall of the second slot 220, thereby making the detachment process of the fixing strap 100 smoother.

[0110] In some embodiments, as Figure 13 As shown, the top surface 1223 is tilted relative to the height direction H of the protrusion 122, so that the width of the second gap 320 gradually increases along the first direction X+. The first direction X+ is parallel to the groove depth direction of the first slot 210 and points from the groove bottom wall 211 to the groove opening of the first slot 210, that is, Figure 13 In the direction to the right.

[0111] Among them, Figure 13 As shown, 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 tilted relative to the second top surface end 1223b in the direction away from the clip body 121, that is, relative to the clip body 121, the first top surface end 1223a is higher than the second top surface end 1223b, so that the width of the second gap 320 can gradually increase along the first direction X+.

[0112] During the process of detaching the fixing strap 100, that is, during the process of rotating the clip 120 to the unlocked position, the top of the protrusion 122 (that is, the top surface 1223) will gradually approach the top wall of the second slot 220, and the right corner of the top of the protrusion 122 (the corner located at the second top surface end 1223b) will have a larger movement amplitude than the left corner of the top of the protrusion 122 (the corner located at the first top surface end 1223a). By setting the width of the second gap 320 to gradually increase along the first direction X+, that is, the closer the second gap 320 is to the right corner of the top of the protrusion 122, the wider the width, the second gap 320 can have sufficient space to avoid the right corner of the top of the protrusion 122, thereby avoiding the right corner of the top of the protrusion 122 from interfering with the top wall of the second slot 220, thereby making the detachment process of the fixing strap 100 smoother.

[0113] In order to prevent the protrusion 122 from falling out of the second slot 220, in some embodiments, as shown in FIG. Figure 13 As shown, the inclination angle θ2 of the top surface 1223 relative to the height direction H of the protrusion 122 is greater than the inclination angle θ1 of the first side surface 1221 relative to the height direction H of the protrusion 122 .

[0114] Among them, Figure 13 As shown, the size of 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 protrusion 122). The larger the inclination angle θ2 of the top surface 1223, the larger 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.

[0115] 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 larger, so that the width of the second side surface 1222 is larger, and the second side surface 1222 with a larger width can have a larger contact area with the right side wall of the second card slot 220, thereby better preventing the protrusion 122 from falling out of the second card slot 220, thereby ensuring the connection reliability between the fixing strap 100 and the device body 200.

[0116] Of course, the top surface 1223 is perpendicular to the height direction H of the protrusion 122 , so that the width of the second gap 320 along its length direction is constant. Setting the second gap 320 in this way can also avoid the movement of the protrusion 122 .

[0117] In order to avoid the motion interference between the corner of the clip body 121 and the first slot side wall 212 during the detachment of the fixing strap 100, in some embodiments, such as Figure 13 and Figure 15As shown, a connecting surface 1213 is provided between the back surface 1212 and the raised portion 122. Figure 13 As shown, when the clamping member 120 is located at the locking position, an avoidance gap 400 is provided between the connecting surface 1213 and the first groove side wall 212 .

[0118] During the process of detaching the fixing strap 100, that is, during the process of rotating the clip 120 to the unlocked position, the first corner formed by the connecting surface 1213 and the back surface 1212 will gradually approach the first groove side wall 212. By providing an avoidance gap 400 between the connecting surface 1213 and the first groove side wall 212, the avoidance gap 400 can avoid the movement of the first corner, thereby avoiding movement interference between the first corner and the first groove side wall 212, thereby making the detachment process of the fixing strap 100 smoother.

[0119] In order to better avoid the motion interference between the corner of the clamping member body 121 and the first groove side wall 212, in some embodiments, such as Figure 13 As shown, the connecting surface 1213 is inclined relative to the height direction H of the protrusion 122, so that the width of the avoidance gap 400 gradually increases along the first direction X+. In this configuration, the width of the avoidance gap 400 increases as it approaches the first corner. As a result, during the process of detaching the fixing strap 100, that is, during the process of rotating the clamping member 120 toward the unlocked position, the avoidance gap 400 has sufficient space to avoid the first corner, better preventing the first corner from interfering with the first groove sidewall 212, thereby making the detachment process of the fixing strap 100 smoother.

[0120] Among them, Figure 13 As shown, the connecting surface 1213 includes a first connecting surface end 1213a arranged close to the raised portion 122, and a second connecting surface end 1213b arranged away from the raised portion 122. The second connecting surface end 1213b deviates from the first connecting surface end 1213a in a direction close to the second end portion 121b, so that the width of the avoidance gap 400 can gradually increase along the first direction X+.

[0121] In some embodiments, as Figure 13 and Figure 15 As shown, a chamfered corner 1214 is provided between the back surface 1212 and the connecting surface 1213. By providing the chamfered corner 1214, the sharp corner formed between the back surface 1212 and the connecting surface 1213 is eliminated, thereby preventing the corner formed between the back surface 1212 and the connecting surface 1213 from scraping the belt body 110 and the first groove sidewall 212 during the rotation of the clamping member 120 around the rotation axis 123, thereby reducing the probability of surface damage to the belt body 110 and the first groove sidewall 212.

[0122] In order to facilitate the movement of the clamping member body 121 to the unlocking position, as shown in FIG. Figure 12aAs shown, the clamping member 120 further includes a pressing portion 124 , which is connected to the second end portion 121 b of the clamping member body 121 . When the pressing portion 124 is pressed, the clamping member 120 moves toward the unlocking position.

[0123] Among them, Figure 12a As shown, the pressing portion 124 and the clamping member body 121 may be an integral structure, but the present invention is not limited thereto. The pressing portion 124 may also be provided separately from the clamping member body 121 .

[0124] In some embodiments, as Figure 12a As shown, the pressing surface 1241 of the pressing portion 124 is provided with an anti-slip structure 1242. In this way, when the pressing portion 124 is pressed by a finger, the anti-slip structure 1242 can prevent the finger from sliding against the pressing surface 1241 of the pressing portion 124, thereby facilitating the pressing portion 124 to be pressed.

[0125] The anti-slip structure 1242 is not unique, e.g. Figure 12a As shown, the anti-skid structure 1242 can be an anti-skid groove; the extension direction of the anti-skid groove can be parallel to the rotation axis 123, or can form a certain angle with the rotation axis 123, which is not specifically limited here. For example, the anti-skid structure 1242 can also be an anti-skid protrusion.

[0126] During the use of the wearable device, the band 110 will inevitably be pulled by external forces. When being pulled, the pulling force on the band 110 will be transmitted to the clamping member 120 through the rotating shaft 123. The clamping member 120 has a tendency to move out of the first clamping slot 210. In order to prevent the clamping member 120 from being pulled out of the first clamping slot 210 by external forces, in some embodiments, such as Figure 12a As shown, the rotating shaft 123 is disposed at the first end portion 121 a of the clip body 121 .

[0127] This arrangement allows the position of the rotating shaft 123 to be close to the protrusion 122. That is, when the belt body 110 is pulled by an external force, the force point of the clamping member 120 is located at the first end 121a (that is, the position of the rotating shaft 123). Because the freedom of the protrusion 122 at the first end 121a is limited by the second clamping groove 220, the clamping member body 121 is not easily separated from the first clamping groove 210 when the belt body 110 is pulled by an external force, thereby ensuring the reliability of the connection between the fixed strap 100 and the device body 200. In addition, the rotating shaft 123 is arranged at the first end 121a, which increases the length of the force arm of the pressing portion 124, thereby making the pressing portion 124 more labor-saving during the pressing process.

[0128] In some embodiments, as Figure 12aAs shown, the height of the second groove sidewall 213 protruding from the groove bottom wall 211 is less than the height of the first groove sidewall 212 protruding from the groove bottom wall 211. This arrangement facilitates the second end portion 121b of the clamping member body 121 to move out of the first clamping groove 210 at the second groove sidewall 213 during detachment of the fixing strap 100, that is, during rotation of the clamping member 120 toward the unlocked position, thereby making the detachment process of the fixing strap 100 smoother.

[0129] In some embodiments, as Figure 12a and Figure 16 As shown, Figure 16 for Figure 12a The wearable device is shown in a partially enlarged view at the second groove sidewall 213. The inner surface 2131 of the second groove sidewall 213 is tilted relative to the groove depth direction of the first slot 210, and the inner surface 2131 of the second groove sidewall 213 is tilted toward the side away from the first slot sidewall 212. In this way, when the fixing strap 100 is installed on the device body 200, the inner surface 2131 of the second groove sidewall 213 can guide the clip body 121, as shown in FIG. Figure 12b As shown, when the second end portion 121b of the card connector body 121 is located at the notch of the first card slot 210, the second end portion 121b of the card connector body 121 can enter the first card slot 210 along the inner surface 2131 of the second slot side wall 213, as shown in FIG. Figure 12a As shown, the fixing strap 100 is snapped into engagement with the device body 200 .

[0130] Among them, Figure 12a and Figure 16 As shown, the inner surface 2131 of the second groove side wall 213 is inclined toward the side away from the first groove side wall 212. Specifically, the inner surface 2131 of the second groove side wall 213 includes a near end 2131a arranged near the groove bottom wall 211, and a far end 2131b arranged away from the groove bottom wall 211, and the far end 2131b deviates from the near end 2131a toward the side away from the first groove side wall 212 (that is, the lower side shown in the figure).

[0131] In some embodiments, as Figure 12aAs shown, the wearable device further includes a magnetic component 500, which is disposed on at least one of the device body 200 and the card connector body 121 (the magnetic component 500 is shown in the figure as being disposed on the device body 200 and the card connector body 121). The magnetic component 500 is used to apply a magnetic force to the card connector body 121, and the magnetic force can cause the card connector body 121 to move toward the direction of the groove bottom wall 211. With this arrangement, the magnetic component 500 can magnetically position the card connector body 121 of the fixing strap 100 during the installation process of the fixing strap 100, thereby facilitating the insertion of the card connector body 121 into the first card slot 210.

[0132] In some embodiments, as Figure 12a As shown, the magnetic component 500 includes a first magnetic component 510 and a second magnetic component 520. The first magnetic component 510 is disposed on the device body 200 at a position corresponding to the slot bottom wall 211. The second magnetic component 520 is disposed on the clip body 121 and is disposed on the side of the rotating shaft 123 near the second end 121b of the clip body 121. A magnetic attraction force can be generated between the first magnetic component 510 and the second magnetic component 520. The first magnetic component 510 and the second magnetic component 520 can both be magnets.

[0133] Since there is magnetic alignment between the first magnetic component 510 and the second magnetic component 520, when the clamping component body 121 is close to the device body 200, under the action of the magnetic force of the first magnetic component 510 and the second magnetic component 520, one end of the clamping component 120 of the fixing strap 100 can automatically attract and clamp with the device body 200. No manual operation is required during the attraction process of the fixing strap 100, which greatly facilitates the installation of the fixing strap 100.

[0134] The following describes in detail the process of the fixing strap 100 automatically attracting and snapping into the device body 200 under the action of magnetic attraction:

[0135] like Figure 12e As shown, first, one end of the fixing strap 100 is provided with the clip 120 close to the first clip slot 210 of the device body 200. Figure 12c As shown, under the action of the magnetic attraction between the first magnetic member 510 and the second magnetic member 520, the clamping member 120 moves toward the direction close to the bottom wall 211 of the first slot 210, and the abutting surface 1211 of the clamping member 120 abuts against the second slot side wall 213. At the same time, the first end 121a of the clamping member 120 extends into the first slot 210 and abuts against the bottom wall 211. At this time, the clamping member 120 is in the unlocked position, and the protrusion 122 is opposite to the notch of the second slot 220. Figure 12c and Figure 12bAs shown, due to the magnetic alignment between the first magnetic member 510 and the second magnetic member 520, the card body 121 is subjected to a magnetic force toward the upper left, and under the action of the magnetic force, the card body 121 moves upward so that the second end 121b of the card body 121 is located at the notch of the first card slot 210; since the inner surface 2131 of the second slot side wall 213 is inclined relative to the groove depth direction of the first card slot 210, under the action of the magnetic force, as shown Figure 12b and Figure 12a As shown, the second end portion 121b of the clip body 121 enters the first clip groove 210 along the inner surface 2131 of the second groove side wall 213, so that the abutting surface 1211 of the clip 120 abuts against the groove bottom wall 211, and the protrusion 122 extends into the second clip groove 220, thereby realizing the clip connection between the fixing strap 100 and the device body 200.

[0136] In some embodiments, as Figure 5 As shown, the device body 200 has a first receiving slot 231 at a position corresponding to the slot bottom wall 211. The first magnetic member 510 is disposed in the first receiving slot 231. A first protective cover 232 is disposed at the notch of the first receiving slot 231. The first protective cover 232 covers the first magnetic member 510. This arrangement protects the first magnetic member 510 within the first receiving slot 231, preventing the first magnetic member 510 from contacting other components and causing damage.

[0137] Among them, Figure 5 and Figure 6 As shown, the first receiving groove 231 is provided on the housing 250 of the device body 200. Further, the first receiving groove 231 is provided on the middle frame 251.

[0138] In some embodiments, as Figure 8 As shown, the connector body 121 is provided with a second receiving slot 1215, in which the second magnetic member 520 is disposed. A second protective cover 1216 is provided at the notch of the second receiving slot 1215, which covers the second magnetic member 520. This arrangement protects the second magnetic member 520 within the second receiving slot 1215, preventing the second magnetic member 520 from contacting other components and being damaged.

[0139] Among them, Figure 8 As shown, the second receiving groove 1215 is disposed on the back surface 1212 of the clip body 121 , thereby preventing the second receiving groove 1215 from being disposed on the abutting surface 1211 .

[0140] The magnetic component 500 in the embodiment of the present application may also include only the first magnetic component 510 , and the clamping component 120 is made of magnetic material, so that a magnetic force can also be generated between the first magnetic component 510 and the clamping component 120 .

[0141] The wearable device in the embodiment of the present application can also replace the magnetic component 500 with an elastic component, which is connected to the clip 120. The elastic component is used to apply an elastic force to the clip 120 to move it toward the locking position. In this way, under the action of the elastic force, the clip 120 can maintain contact with the bottom wall 211 of the first slot 210, which is beneficial to improving the connection reliability between the fixing strap 100 and the device body 200.

[0142] The specific type of elastic component is not limited. For example, the elastic component can be a spring connected between the groove wall of the clip receiving groove 114 and the pressing portion 124 of the clip 120. When the clip 120 is in the unlocked position, the spring is in a compressed state. For another example, the elastic component can also be a torsion spring, which is sleeved on the rotating shaft 123. One connecting arm of the torsion spring abuts against the groove wall of the clip receiving groove 114, and the other connecting arm of the torsion spring abuts against the clip body 121. When the clip 120 is in the unlocked position, the torsion spring is in a force-storing state.

[0143] It should be noted that the above embodiment is described by taking the example of providing the first card slot 210 on the shell 250 and providing the snap-fitting member 120 on the fixing strap 100. It is understandable that the snap-fitting member 120 may also be provided on the shell 250 and the first card slot 210 may also be provided on the fixing strap 100.
