[0001] This application claims priority to Chinese patent application filed on September 23, 2024, with application number 202422332582.5 and entitled "Wearable device and its fixing strap and device body", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic device technology, and in particular to a wearable device and its fixing strap and device body. Background Technology
[0003] Wearable devices are portable electronic devices that can be worn on the body. With the development of electronic technology, various types of wearable devices are constantly emerging, such as smartwatches, smart bracelets, and smart glasses. Wearable devices have diverse functions, convenient operation and interaction, stylish appearance and design, as well as long battery life and durability, which can provide users with a more intelligent, convenient and healthy lifestyle.
[0004] Wearable devices mainly consist of a main body and a fixing strap. The fixing strap is used to wear the main body on the body, and the fixing strap is detachably connected to the main body to facilitate the replacement of the fixing strap. The design of the detachable connection structure between the fixing strap and the main body directly affects the efficiency of assembling and disassembling the fixing strap, and has become one of the important topics in the industry. Summary of the Invention
[0005] Embodiments of this application provide a wearable device and its fixing strap and device body, which solves the problem that the detachable connection structure between the fixing strap and the device body of the wearable device in the related art is relatively complex.
[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:
[0007] In a first aspect, embodiments of this application provide a wearable device, including a device body and a fixing strap detachably connected to the device body; the device body is provided with a first slot, the first slot having a bottom wall, and a first slot side wall and a second slot side wall respectively disposed at opposite sides of the bottom wall, the first slot side wall being provided with a second slot; the fixing strap includes a strap body and a snap-fit member disposed at one end of the strap body, the snap-fit member including a snap-fit member body and a protrusion, the snap-fit member body having opposite first end and second end, the protrusion being disposed at the first end and protruding from the snap-fit member body in a direction away from the second end. The main body of the latching component is rotatably connected to the belt body via a pivot, allowing the latching component to move between a locked position and an unlocked position. When the latching component is in the locked position, the main body of the latching component extends into the first latching groove and abuts against the bottom wall of the groove, while the protrusion extends into the second latching groove, so that the fixing strap is latched to the equipment body. There is a clearance space between the protrusion and the groove wall of the second latching groove, which is used to avoid the protrusion, allowing the latching component to move to the unlocked position. When the latching component is in the unlocked position, the second end is located at the edge of the groove opening of the first latching groove, and the main body of the latching component can be moved out of the first latching groove, so that the fixing strap is separated from the equipment body.
[0008] The wearable device in this embodiment can achieve the engagement and disengagement of the fixing strap and the device body by rotating the locking member between the locking position and the unlocking position. That is, the locking member serves both the engagement and unlocking functions. This eliminates the need for additional unlocking components that cooperate with the movement of the locking member, thereby simplifying the detachable connection structure between the fixing strap and the device body and improving the reliability of the connection between the fixing strap and the device body.
[0009] In some embodiments of the first aspect, the main body of the snap-fit component has an abutment surface for abutting against the bottom wall of the slot. The protrusion includes a first side surface disposed near the abutment surface and a second side surface disposed away from the abutment surface. The clearance space includes a first gap located between the first side surface and the slot wall of the second snap-fit slot. This arrangement can prevent movement interference between the protrusion and the slot side wall of the second snap-fit slot.
[0010] In some embodiments of the first aspect, the first side is inclined relative to the height direction of the protrusion, and the first side is inclined towards the side closer to the second side. Specifically, the first side has a first side end located near the main body of the latching member, and a second side end located away from the main body of the latching member, with the second side end offset from the first side end towards the side closer to the second side. This arrangement better avoids movement interference between the top of the protrusion and the sidewall of the second slot.
[0011] In some embodiments of the first aspect, the protrusion further includes a top surface connected between the first side surface and the second side surface, and the clearance space includes a second gap located between the top surface and the groove wall of the second slot. This arrangement can prevent motion interference between the protrusion and the top wall of the second slot.
[0012] 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 the first direction; the first direction is parallel to the groove depth direction of the first slot and points from the bottom wall of the slot to the opening of the first slot. This arrangement can avoid motion interference between the corner of the top of the protrusion and the top wall of the second slot.
[0013] In some embodiments of the first aspect, the angle of inclination of the top surface relative to the height direction of the protrusion is greater than the angle of inclination of the first side surface relative to the height direction of the protrusion. This arrangement better prevents the protrusion from dislodging from the second slot.
[0014] In some embodiments of the first aspect, the snap-fit body has an abutment surface and a back surface opposite to the abutment surface, the abutment surface being used to abut against the bottom wall of the groove; a connecting surface is provided between the back surface and the protrusion, and when the snap-fit is in the locked position, there is a clearance gap between the connecting surface and the side wall of the first groove. This arrangement can prevent movement interference between the corner of the snap-fit body and the side wall of the first groove during the removal of the fixing strap.
[0015] 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 groove depth direction of the first slot and points from the bottom wall of the slot to the opening of the first slot. This arrangement can better avoid motion interference between the corner of the snap-fit body and the side wall of the first slot.
[0016] In some embodiments of the first aspect, a rounded corner is provided between the back surface and the connecting surface. This arrangement prevents the corner formed between the back surface and the connecting surface from scraping against the belt and the sidewall of the first groove during the rotation of the snap-fit component around the pivot.
[0017] In some embodiments of the first aspect, the height by which the second groove sidewall protrudes from the groove bottom wall is less than the height by which the first groove sidewall protrudes from the groove bottom wall. This arrangement allows the second end b of the snap-fit body to easily move out of the first snap-fit groove from the second groove sidewall during the removal of the fixing strap.
[0018] 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 away from the first groove sidewall. Specifically, the inner surface of the second groove sidewall is inclined away from the first groove sidewall by including a proximal end near the bottom wall of the groove and a distal end away from the bottom wall of the groove, with the distal end offset from the proximal end towards the side away from the first groove sidewall. This arrangement allows the inner surface of the second groove sidewall to guide the main body of the fastener during the installation of the fixing strap on the equipment body.
[0019] In some embodiments of the first aspect, the wearable device further includes a magnetic attraction component disposed on at least one of the device body and the snap-fit body. The magnetic attraction component applies a magnetic force to the snap-fit body, which causes the snap-fit body to move toward the bottom wall of the slot. This configuration allows the magnetic attraction component to magnetically position the snap-fit body that holds the strap in place.
[0020] In some embodiments of the first aspect, the magnetic suction component includes a first magnetic suction member and a second magnetic suction member. The first magnetic suction member is disposed at a position on the bottom wall of the groove corresponding to the main body of the device, and the second magnetic suction member is disposed on the main body of the snap-fit component and on the side of the rotating shaft near the second end b of the snap-fit component body. Magnetic attraction can be generated between the first magnetic suction member and the second magnetic suction member. With this configuration, one end of the fixing strap with the snap-fit member can automatically attract and snap into the main body of the device, eliminating the need for manual operation during the attraction process of the fixing strap.
[0021] In some embodiments of the first aspect, the main body of the device is provided with a first receiving groove at the position corresponding to the bottom wall of the groove, the first magnetic attracting member is disposed in the first receiving groove, and a first protective cover is provided at the opening of the first receiving groove, the first protective cover covering the first magnetic attracting member. With this arrangement, the first protective cover can protect the first magnetic attracting member in the first receiving groove.
[0022] In some embodiments of the first aspect, the snap-fit body is provided with a second receiving groove, the second magnetic member is disposed in the second receiving groove, and a second protective cover is provided at the opening of the second receiving groove, the second protective cover covering the second magnetic member. With this arrangement, the second protective cover can protect the second magnetic member within the second receiving groove.
[0023] In some embodiments of the first aspect, the latching member further includes a pressing portion connected to a second end of the latching member body, wherein the pressing portion moves the latching member toward the unlocked position when pressed. This configuration facilitates the movement of the latching member body toward the unlocked position.
[0024] In some embodiments of the first aspect, the pivot is located at the first end of the snap-fit body. This arrangement prevents the snap-fit body from easily disengaging from the first slot when the belt is subjected to external force; simultaneously, it makes the pressing part less strenuous during pressing.
[0025] In some embodiments of the first aspect, an anti-slip structure is provided on the pressing surface of the pressing part. This configuration prevents the finger from sliding between the finger and the pressing surface of the pressing part.
[0026] In some embodiments of the first aspect, an adapter is embedded inside the belt body. The snap-fit component, the pivot, and the adapter are all metal or alloy parts, while the belt body is made of plastic. The pivot is connected to the adapter. This arrangement ensures the reliability of the pivot's installation.
[0027] In some embodiments of the first aspect, the adapter includes two adapter arms spaced apart along the width direction of the belt, and an intermediate connecting arm connected between the two adapter arms. The intermediate connecting arm and the two adapter arms form a U-shape. A rotating shaft is disposed between the two adapter arms, and both ends of the rotating shaft are connected to the two adapter arms respectively. This arrangement allows the two adapter arms to limit the rotation of the shaft, preventing it from detaching from the adapter, thereby improving the reliability of the connection between the shaft and the adapter.
[0028] In some embodiments of the first aspect, the belt body includes a first belt surface and a second belt surface disposed opposite to each other, and a belt end face connecting the first belt surface and the second belt surface. The first belt surface is the outer surface of the belt body, and the second belt surface is provided with a snap-fit receiving groove that penetrates the belt end face. At least a portion of the snap-fit is disposed in the snap-fit receiving groove, and a protrusion extends from the snap-fit receiving groove and protrudes from the belt end face. This arrangement can reduce the space occupied by the snap-fit outside the belt body, thereby making the structure of the fixing strap more compact.
[0029] Secondly, embodiments of this application provide a fixing strap for detachably connecting to the main body of a wearable device, including a strap body and a latching member disposed at one end of the strap body; the latching member includes a latching member body, a protrusion, and a pressing part; the latching member body has a first end and a second end opposite to each other, and an abutment surface connecting the first end and the second end, the abutment surface being used to abut against the main body of the device; the protrusion is disposed at the first end and protrudes from the latching member body in a direction away from the second end; the protrusion includes a first side surface disposed near the abutment surface and a second side surface disposed away from the abutment surface, the first side surface being inclined relative to the height direction of the protrusion, and the first side surface being inclined towards the side closer to the second side surface; the pressing part is connected to the second end, and the latching member body is rotatably connected to the strap body via a pivot, so that the latching member can move between a locked position and an unlocked position; when the pressing part is pressed, the latching member moves to the unlocked position.
[0030] Specifically, the first side is inclined towards the side closer to the second side as follows: the first side has a first side end that is close to the main body of the snap-fit component and a second side end that is far away from the main body of the snap-fit component, and the second side end is offset from the first side end towards the side closer to the second side.
[0031] The beneficial effects of the fixing strap in this embodiment are the same as those of the wearable device in the first aspect, and will not be repeated here.
[0032] In some embodiments of the second aspect, the protrusion further includes a top surface, which is connected between the first side surface and the second side surface, and is inclined relative to the height direction of the protrusion. 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, and the first top surface end is raised relative to the second top surface end in a direction away from the main body of the snap-fit component. This arrangement can prevent motion interference between the corner of the top of the protrusion and the top wall of the second slot.
[0033] In some embodiments of the second aspect, the angle of inclination of the top surface relative to the height direction of the protrusion is greater than the angle of inclination of the first side surface relative to the height direction of the protrusion. This arrangement better prevents the protrusion from dislodging from the second slot.
[0034] In some embodiments of the second aspect, the snap-fit body further has a back surface opposite to the abutment surface, and a connecting surface is provided between the back surface and the protrusion. The connecting surface is inclined relative to the height direction of the protrusion. The connecting surface includes a first connecting surface end near the protrusion and a second connecting surface end away from the protrusion, with the second connecting surface end offset from the first connecting surface end in a direction closer to the second end. This arrangement can better prevent movement interference between the corners of the snap-fit body and the sidewall of the first groove.
[0035] In some embodiments of the second aspect, a rounded corner is provided between the back surface and the connecting surface. This arrangement prevents the corner formed between the back surface and the connecting surface from scraping against the belt and the sidewall of the first groove during the rotation of the snap-fit component around the pivot.
[0036] In some embodiments of the second aspect, the snap-fit body is provided with a second magnetic chuck, which is located on the side of the rotating shaft near the second end. With this configuration, the second magnetic chuck on the snap-fit body can attract the first magnetic chuck on the device body, thus providing magnetic positioning for the snap-fit body; moreover, the end of the fixing strap with the snap-fit can automatically attract and snap into the device body, eliminating the need for manual operation during the attraction process.
[0037] In some embodiments of the second aspect, the snap-fit body is provided with a second receiving groove, the second magnetic component is disposed in the second receiving groove, and a second protective cover is provided at the opening of the second receiving groove, the second protective cover covering the second magnetic component. With this arrangement, the second protective cover can protect the second magnetic component within the second receiving groove.
[0038] In some embodiments of the second aspect, the pivot is located at the first end of the snap-fit body. This arrangement prevents the snap-fit body from easily disengaging from the first slot when the belt is subjected to external force; simultaneously, it makes the pressing part less strenuous during pressing.
[0039] In some embodiments of the second aspect, an adapter is embedded inside the belt body. The snap-fit component, the pivot, and the adapter are all metal or alloy parts, while the belt body is made of plastic. The pivot is connected to the adapter. This configuration ensures the reliability of the pivot's installation.
[0040] In some embodiments of the second aspect, the adapter includes two adapter arms spaced apart along the width direction of the belt, and an intermediate connecting arm connected between the two adapter arms. The intermediate connecting arm and the two adapter arms form a U-shape. A rotating shaft is disposed between the two adapter arms, and both ends of the rotating shaft are connected to the two adapter arms respectively. This arrangement allows the two adapter arms to limit the rotation of the shaft, preventing it from detaching from the adapter, thereby improving the reliability of the connection between the shaft and the adapter.
[0041] In some embodiments of the second aspect, the belt body includes a first belt surface and a second belt surface disposed opposite to each other, and a belt end face connecting the first belt surface and the second belt surface. The first belt surface is the outer surface of the belt body, and the second belt surface is provided with a snap-fit receiving groove that penetrates the belt end face. At least a portion of the snap-fit is disposed in the snap-fit receiving groove, and a protrusion extends from the snap-fit receiving groove and protrudes from the belt end face. This arrangement can reduce the space occupied by the snap-fit outside the belt body, thereby making the structure of the fixing strap more compact.
[0042] Thirdly, embodiments of this application provide a main body for a wearable device, which is detachably connected to a fixing strap. The main body includes a housing, a first slot on the housing, the first slot having a bottom wall, and a first side wall and a second side wall respectively disposed at opposite sides of the bottom wall. The first side wall has a second slot. The second side wall protrudes from the bottom wall at a height less than the first side wall protruding from the bottom wall.
[0043] The beneficial effects of the wearable device body in this embodiment are the same as those of the wearable device in the first aspect, and will not be repeated here.
[0044] In some embodiments of the third 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 away from the first groove sidewall. Specifically, the inner surface of the second groove sidewall is inclined away from the first groove sidewall by including a proximal end near the bottom wall of the groove and a distal end away from the bottom wall of the groove, with the distal end offset from the proximal end towards the side away from the first groove sidewall. This arrangement allows the inner surface of the second groove sidewall to guide the main body of the fastener during the installation of the fixing strap on the equipment body.
[0045] In some embodiments of the third aspect, the housing is provided with a first magnetic attractor at the position corresponding to the bottom wall of the groove. With this arrangement, the second magnetic attractor on the main body of the snap-fit component can attract the first magnetic attractor on the housing, which can play a role in magnetic positioning of the snap-fit component; moreover, the end of the snap-fit component on the fixing strap can automatically attract and snap with the main body of the device, and no manual operation is required during the attraction process of the fixing strap.
[0046] In some embodiments of the third aspect, the housing has a first receiving groove at the position of the bottom wall of the corresponding groove, the first magnetic member is disposed in the first receiving groove, and a first protective cover is provided at the opening of the first receiving groove, the first protective cover covering the first magnetic member.

[0067] The technical solutions in some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0068] Wearable devices are portable electronic devices that can be worn on the body. With the development of electronic technology, various types of wearable devices are constantly emerging, such as smartwatches, smart bracelets, and smart glasses. Wearable devices have diverse functions, convenient operation and interaction, stylish appearance and design, as well as long battery life and durability, which can provide users with a more intelligent, convenient and healthy lifestyle.
[0069] Wearable devices mainly consist of a main body and a fixing strap. The fixing strap is used to wear the main body on the body, and the fixing strap is detachably connected to the main body to facilitate the replacement of the fixing strap. The design of the detachable connection structure between the fixing strap and the main body directly affects the efficiency of assembling and disassembling the fixing strap, and has become one of the important topics in the industry.
[0070] One type of wearable device in the related technology has a fixing strap connected to the main body of the device via spring ears. Tools are required to remove the fixing strap, making the installation and removal of the fixing strap inconvenient.
[0071] To facilitate the installation and removal of the fixing strap, another wearable device in related technologies uses a snap-fit structure with an unlock button to connect the fixing strap to the main body of the device. When the fixing strap is installed, the main body of the device is snapped into the fixing strap by the snap-fit, and the unlock button restricts the movement of the snap-fit to lock it in place. When the fixing strap needs to be removed, pressing the unlock button releases the movement lock on the snap-fit, allowing the snap-fit to detach from the fixing strap, thus achieving the separation of the fixing strap from the main body of the device.
[0072] However, in this type of wearable device, the fastening strap and the main body are connected and unlocked via a snap-fit mechanism and an unlock button. The unlock button and the snap-fit mechanism require movement and coordination, which not only increases the number of parts but also makes the detachable connection structure between the fastening strap and the main body more complex, which is not conducive to improving the reliability of the connection.
[0073] Therefore, this application provides a wearable device and its fixing strap and device body. The fixing strap is provided with a snap-fit component. The snap-fit component is rotated to different positions to achieve snap-fit and unlock. This eliminates the need for additional unlocking components that cooperate with the movement of the snap-fit component, thereby simplifying the detachable connection structure between the fixing strap and the device body and improving the connection reliability between the fixing strap and the device body.
[0074] The wearable device in this application embodiment can be a smartwatch, smart bracelet, smart glasses, or other electronic device that can be worn on the body. The following uses a smartwatch as an example to specifically describe the detachable connection structure between the fixing strap and the main body of the device. Other types of wearable devices can be set up with reference to the detachable connection structure in the smartwatch embodiment, and will not be described in detail here.
[0075] Figure 1 is a structural schematic diagram of a wearable device (smartwatch) in some embodiments of this application, Figure 2 is a structural schematic diagram of the wearable device in Figure 1 from another perspective, and Figure 3 is an exploded view of the wearable device in Figure 1. As shown in Figures 1, 2 and 3, the wearable device includes a device body 200 and a fixing strap 100 detachably connected to the device body 200.
[0076] The device includes 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 the device body 200. The fixing straps 100a and fixing strap 100b are connected together by a locking structure, forming a ring structure with the device body 200. This ring structure can be worn on the human body (e.g., the wrist), thus enabling the wearable device to be worn on the human body. It should be noted that fixing straps 100a and fixing strap 100b can also use other connection methods besides the locking structure, and this embodiment of the application is not limited to this.
[0077] Figure 4 is a structural schematic diagram of the main body 200 of the wearable device in Figure 1, and Figure 5 is a cross-sectional view (AA) of the main body of the device in Figure 4. As shown in Figures 4 and 5, the main body 200 is provided with a first slot 210, the first slot 210 has a bottom wall 211, and a first side wall 212 and a second side wall 213 respectively provided at opposite sides of the bottom wall 211. The first side wall 212 is provided with a second slot 220.
[0078] The bottom wall 211 of the slot is the slot wall opposite to the slot opening in the first slot 210. As shown in Figure 5, the second slot 220 can be set at the position of the first slot side wall 212 near the bottom wall 211 of the first slot 210, that is, one side wall of the second slot 220 is flush with the bottom wall 211 of the first slot 210. However, it is not limited to this, and the second slot 220 can be set at other positions of the first slot side wall 212.
[0079] The main body 200 is the core component of the wearable device, used to achieve specific functions such as health monitoring, activity tracking, and notification reminders. The main body 200 includes a housing 250 and a cover 240. One side of the housing 250 has an opening, and the cover 240 is disposed at the opening of the housing 250. The inner side of the cover 240 is used to house functional components such as a display screen, circuit board, and battery.
[0080] As shown in Figures 4 and 5, there are two first slots 210, which are respectively disposed on two opposite side walls of the housing 250. Each first slot 210 is engaged with a corresponding fixing strap 100. Along the thickness direction H of the equipment body 200, the first slot side wall 212 of the first slot 210 is disposed on the side of the first slot 210 near the cover plate 240, and the second slot side wall 213 is disposed on the side of the first slot 210 away from the cover plate 240.
[0081] As shown in Figures 5 and 6, Figure 6 is an exploded view of the main body 200 of the device shown in Figure 4. The housing 250 includes a middle frame 251 and a rear cover 252. The middle frame 251 is a metal or alloy part, and the rear cover 252 is a plastic part. The middle frame 251 is disposed between the cover plate 240 and the rear cover 252.
[0082] To reduce the deformation of the back cover 252 under external forces, in some embodiments, as shown in Figures 5 and 6, the back cover 252 has a notch 2521 at its edge, and a flange 2511 is integrally provided on the middle frame 251, which extends into the notch 2521. Since the flange 2511 is a metal or alloy part, its hardness is greater than that of the back cover 252. By extending the flange 2511 into the notch 2521, the flange 2511 can provide support and reinforcement for the back cover 252, thereby helping to reduce the deformation of the back cover 252 under external forces.
[0083] As shown in Figure 6, the second groove sidewall 213 is disposed on the flange 2511, and the middle frame 251 and the rear cover 252 form the first slot 210.
[0084] Of course, the main body 200 is not limited to the above structure. The main body 200 can also be configured with other structures depending on the type of wearable device. For example, the housing 250 may include a cover plate 240 and a back cover 252, but may not include the middle frame 251.
[0085] Figure 7 is a partial view of the fixing strap 100 of the wearable device in Figure 1, Figure 8 is a BB cross-sectional view of the fixing strap 100 in Figure 7, and Figure 9 is an exploded view of the fixing strap 100 in Figure 7. As shown in Figures 7 and 8, the fixing strap 100 includes a strap body 110 and a snap fastener 120 disposed at one end of the strap body 110. The snap fastener 120 includes a snap fastener body 121 and a protrusion 122. The snap fastener body 121 has a first end 121a and a second end 121b opposite to each other. The protrusion 122 is disposed at the first end 121a and protrudes from the snap fastener body 121 in a direction away from the second end 121b (that is, the upward direction in Figure 8). The snap fastener body 121 is rotatably connected to the strap body 110 via a pivot 123.
[0086] As shown in Figures 7 and 8, the protrusion 122 and the main body 121 of the snap-fit component are an integral structure, but this is not a limitation. The protrusion 122 and the main body 121 of the snap-fit component can also be separately arranged, with the protrusion 122 fixed to the main body 121 of the snap-fit component. It can be understood that the up and down direction in Figure 8 can be understood as the height direction H of the protrusion 122.
[0087] In some embodiments, as shown in Figures 7, 8 and 9, the belt body 110 includes a first belt surface 111 and a second belt surface 112 disposed opposite to each other, and a belt end face 113 connected between the first belt surface 111 and the second belt surface 112. The first belt surface 111 is the outer surface of the belt body 110. The second belt surface 112 is provided with a snap-fit receiving groove 114, which penetrates the belt end face 113. At least a portion of the snap-fit 120 is disposed in the snap-fit receiving groove 114, and a protrusion 122 extends out of the snap-fit receiving groove 114 and protrudes from the belt end face 113.
[0088] By placing at least a portion of the snap fastener 120 in the snap fastener receiving groove 114, the space occupied by the snap fastener 120 outside the strap body 110 can be reduced, thereby making the structure of the fixing strap 100 more compact; at the same time, the snap fastener receiving groove 114 can protect the snap fastener 120 and reduce damage to the surface of the snap fastener 120 from other external objects.
[0089] As shown in Figure 9, the snap-fit body 121 can be rotatably connected to the side wall of the snap-fit receiving groove 114 via the rotating shaft 123.
[0090] Of course, the end of the belt body 110 may not need to be provided with the snap-fit receiving groove 114. The belt body 110 is locally thinned at the end to form a thinned section, and the snap-fit 120 is provided on the inner side of the thinned section of the belt body 110.
[0091] In some embodiments, as shown in Figures 9 and 10, Figure 10 is a schematic diagram of the installation of the pivot 123 of the fixing strap 100 in Figure 7. An adapter 130 is embedded inside the strap body 110. The snap-fit component 120, the pivot 123, and the adapter 130 are all metal or alloy parts, while the strap body 110 is made of plastic. The pivot 123 is connected to the adapter 130. By connecting the pivot 123 to the adapter 130, that is, connecting metal parts (alloy parts) to metal parts (alloy parts), the installation reliability of the pivot 123 can be ensured, thereby preventing the pivot 123 from detaching from the strap body 110.
[0092] The materials of the snap-fit component 120, the rotating shaft 123, and the adapter 130 can be stainless steel, copper, etc.; the material of the belt body 110 can be fluororubber, silicone, thermoplastic silicone rubber, etc. The connection method between the rotating shaft 123 and the adapter 130 is not unique. The rotating shaft 123 can be rotatably connected to the adapter 130, and the snap-fit component 120 is fixed to the rotating shaft 123 in the circumferential direction; the rotating shaft 123 can also be fixedly connected to the adapter 130, and the through hole on the snap-fit component 120 is rotatably engaged with the rotating shaft 123.
[0093] In some embodiments, as shown in Figures 9 and 10, the adapter 130 includes two adapter arms 131 spaced apart along the width direction Y of the belt 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. A rotating shaft 123 is disposed between the two adapter arms 131, and both ends of the rotating shaft 123 are connected to the two adapter arms 131 respectively. This configuration allows the two adapter arms 131 to limit the rotation of the rotating shaft 123, preventing it from detaching from the adapter 130. This improves the connection reliability between the rotating shaft 123 and the adapter 130, and consequently, the connection reliability between the rotating shaft 123 and the belt 110.
[0094] Of course, the number of adapter arms 131 in the adapter 130 can also be one. The adapter arm 131 and the intermediate connecting arm 132 are in an L-shaped structure, and one end of the rotating shaft 123 is connected to the adapter arm 131.
[0095] Figure 11 is a top view of the wearable device in Figure 1 after the fixing strap 100 on one side has been removed. Figure 12a is a CC cross-sectional view of the wearable device in Figure 11. Figure 12b is a state diagram of the wearable device in Figure 1 during the disassembly and assembly process. Figure 12c is a state diagram of the wearable device in Figure 1 during the disassembly and assembly process. Figure 12d is a state diagram of the wearable device in Figure 1 during the disassembly and assembly process. Figure 12e is a state diagram of the wearable device in Figure 1 after the fixing strap 100 has been removed from the main body 200.
[0096] As shown in Figures 11, 12a and 12b, the latch 120 can move between a locked position (as shown in Figure 12a) and an unlocked position (as shown in Figure 12b).
[0097] As shown in Figure 12a, when the latching member 120 is in the locked position, the main body 121 of the latching member extends into the first latching groove 210 and abuts against the bottom wall 211 of the groove, and the protrusion 122 extends into the second latching groove 220 so that the fixing strap 100 is latched with the main body 200 of the device; there is a clearance space 300 between the protrusion 122 and the groove wall of the second latching groove 220, which is used to avoid the protrusion 122, so that the latching member 120 can move to the unlocked position.
[0098] It is important to understand that, as shown in Figure 12a, when the locking member 120 is in the locked position, the second locking groove 220 can restrict the degree of freedom of the locking member 120 in the groove depth direction X along the first locking groove 210, and the groove sidewalls of the first locking groove 210 (such as the first groove sidewall 212 and the second groove sidewall 213) can restrict the degree of freedom of the locking member 120 in the groove depth direction X perpendicular to the first locking groove 210, thereby realizing the locking of the fixing strap 100 with the equipment body 200 and preventing the fixing strap 100 from detaching from the equipment body 200 under the pull of external force.
[0099] As shown in Figure 12b, when the snap fastener 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 snap fastener body 121 can be moved out of the first slot 210 so that the fixing strap 100 is separated from the device body 200.
[0100] The process of separating the fixing strap 100 from the device body 200 can be seen in Figures 12b to 12e. As shown in Figure 12b, when the latching member 120 is in the unlocked position, since the second end 121b is located at the edge of the first slot 210, by pulling the fixing strap 100 away from the side wall 212 of the first slot outward (e.g., towards the lower right in the figure), as shown in Figure 12c, the second end of the latching member body 121 can be released. 121b is moved out of the first slot 210, and at the same time, the protrusion 122 is moved out of the second slot 220. After the protrusion 122 is moved out of the second slot 220, the fixing strap 100 is 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 in Figures 12d and 12e. The entire snap fastener 120 can be moved out of the first slot 210, thereby separating the fixing strap 100 from the main body of the equipment 200.
[0101] The installation process of the fixing strap 100 is the reverse of the disassembly process, as shown in Figure 12e. The end of the fixing strap 100 with the snap fastener 120 is brought close to the first slot 210 of the device body 200. As shown in Figures 12d and 12c, under the action of human force, elastic force, magnetic attraction, and other driving forces, the snap fastener 120 is rotated to the unlocked position, and the protrusion 122 extends into the first slot 210 and is opposite to the opening of the second slot 220. As shown in Figures 12b and 12a, under the action of human force, magnetic attraction, and other driving forces, the snap fastener 120 moves towards the second slot 220, so that the protrusion 122 extends into the second slot 220, and the snap fastener body 121 extends into the first slot 210 and abuts against the bottom wall 211 of the slot, thereby realizing the snap fastening of the fixing strap 100 and the device body 200.
[0102] In this embodiment of the wearable device, the locking member 120 can rotate between the locked and unlocked positions to achieve the locking and unlocking of the fixing strap 100 and the device body 200. That is, the locking member 120 serves both the locking and unlocking functions. This eliminates the need for additional unlocking components that cooperate with the movement of the locking member 120, thereby simplifying the detachable connection structure between the fixing strap 100 and the device body 200 and improving the reliability of the connection between the fixing strap 100 and the device body 200.
[0103] In some embodiments, as shown in FIG12a, the snap-fit body 121 has an abutment surface 1211 and a back surface 1212 disposed opposite to the abutment surface 1211. The abutment surface 1211 and the back surface 1212 are respectively connected between the first end 121a and the second end 121b. The abutment surface 1211 is used to abut against the bottom wall 211 of the groove.
[0104] As shown in Figure 13, which is a partially enlarged view of the wearable device in Figure 12a at the second slot 220, the protrusion 122 includes a first side surface 1221 located near the abutment surface 1211 and a second side surface 1222 located away from the abutment surface 1211. The clearance space 300 includes a first gap 310 located between the first side surface 1221 and the slot wall of the second slot 220. The first gap 310 is formed by the first side surface 1221, the left side wall of the second slot 220, and the top wall of the second slot 220.
[0105] During the process of removing the fixing strap 100, that is, during the process of the snap fastener 120 rotating towards the unlock 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 1221 and the slot wall of the second slot 220, the first gap 310 can avoid the movement of the protrusion 122, and avoid the movement interference between the protrusion 122 and the left side wall of the second slot 220, thereby making the removal process of the fixing strap 100 smoother.
[0106] In some embodiments, as shown in Figures 13 and 14, Figure 14 is a structural schematic diagram of the snap-fit connector 120 of the wearable device in Figure 12a. The first side 1221 is inclined in the height direction H relative to the protrusion 122, and the first side 1221 is inclined towards the side closer to the second side 1222. This arrangement allows the first gap 310 to be wider closer to the top of the protrusion 122, so that during the process of the snap-fit connector 120 rotating towards the unlock position, the first gap 310 has sufficient space to avoid the top of the protrusion 122, preventing movement interference between the top of the protrusion 122 and the left sidewall of the second slot 220, thereby making the removal process of the fixing strap 100 smoother.
[0107] As shown in Figures 13 and 14, the first side 1221 is inclined towards the side closer to the second side 1222 in the following ways: the first side 1221 has a first side end 1221a that is close to the main body 121 of the snap-fit component, and a second side end 1221b that is far away from the main body 121 of the snap-fit component, and the second side end 1221b is offset from the first side end 1221a towards the side closer to the second side 1222.
[0108] Of course, the first side 1221 can also be set 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. This setting of the first gap 310 can also avoid the movement of the protrusion 122.
[0109] In some embodiments, as shown in Figures 13, 14, and 15, Figure 15 is a structural schematic diagram of the snap-fit member 120 shown in Figure 14 from another perspective. The protrusion 122 also includes a top surface 1223, which connects the first side surface 1221 and the second side surface 1222. The clearance space 300 includes a second gap 320, which is located between the top surface 1223 and the groove wall of the second snap-fit groove 220 (that is, the top wall of the second snap-fit groove 220).
[0110] During the process of removing the fixing strap 100, that is, during the process of the snap fastener 120 rotating towards the unlock 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, thus avoiding movement interference between the protrusion 122 and the top wall of the second slot 220, thereby making the removal process of the fixing strap 100 smoother.
[0111] In some embodiments, as shown in FIG13, the top surface 1223 is inclined 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 bottom wall 211 of the slot to the opening of the first slot 210, which is the rightward direction in FIG13.
[0112] As shown in Figure 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 raised relative to the second top surface end 1223b in a direction away from the snap-fit body 121. That is, relative to the snap-fit 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+.
[0113] During the process of removing the fixing strap 100, that is, during the rotation of the snap fastener 120 towards the unlock position, the top of the protrusion 122 (i.e., the top surface 1223) will gradually approach the top wall of the second slot 220. The right corner of the top of the protrusion 122 (the corner located at the second top surface end 1223b) has a greater range of motion 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 second gap 320 is wider as it gets closer to the right corner of the top of the protrusion 122, the second gap 320 can have sufficient space to avoid the right corner of the top of the protrusion 122, thus avoiding movement interference between the right corner of the top of the protrusion 122 and the top wall of the second slot 220, thereby making the removal process of the fixing strap 100 smoother.
[0114] To prevent the protrusion 122 from dislodging from the second slot 220, in some embodiments, as shown in FIG13, the tilt angle θ2 of the top surface 1223 relative to the height direction H of the protrusion 122 is greater than the tilt angle θ1 of the first side surface 1221 relative to the height direction H of the protrusion 122.
[0115] As shown in Figure 13, the size of the inclination angle θ2 of the top surface 1223 is related to the width of the second side surface 1222 (i.e., 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.
[0116] By setting the tilt angle θ2 of the top surface 1223 to be greater than the tilt angle θ1 of the first side surface 1221, the tilt angle θ2 of the top surface 1223 can be larger, thereby making the width of the second side surface 1222 larger. The wider second side surface 1222 can have a larger contact area with the right sidewall of the second slot 220, which can better prevent the protrusion 122 from falling out of the second slot 220, thus ensuring the reliability of the connection between the fixing strap 100 and the equipment body 200.
[0117] Of course, the top surface 1223 is perpendicular to the height direction H of the protrusion 122, so the width of the second gap 320 along its length is constant. This setting of the second gap 320 can also avoid the movement of the protrusion 122.
[0118] To avoid motion interference between the corner of the snap fastener body 121 and the first groove sidewall 212 during the removal of the fixing strap 100, in some embodiments, as shown in Figures 13 and 15, a connecting surface 1213 is provided between the back surface 1212 and the protrusion 122. As shown in Figure 13, when the snap fastener 120 is in the locked position, there is a clearance gap 400 between the connecting surface 1213 and the first groove sidewall 212.
[0119] During the process of removing the fixing strap 100, that is, during the process of the snap fastener 120 rotating towards the unlock 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 a clearance gap 400 between the connecting surface 1213 and the first groove side wall 212, the clearance gap 400 can avoid the movement of the first corner, avoid the first corner from interfering with the movement of the first groove side wall 212, and thus make the removal process of the fixing strap 100 smoother.
[0120] To better prevent motion interference between the corner of the snap-fit body 121 and the side wall 212 of the first groove, in some embodiments, as shown in FIG13, the connecting surface 1213 is inclined in the height direction H relative to the protrusion 122, so that the width of the clearance 400 gradually increases along the first direction X+. With this setting, the clearance 400 is wider as it gets closer to the first corner. In this way, during the process of removing the fixing strap 100, that is, during the process of the snap-fit 120 rotating to the unlock position, the clearance 400 has sufficient space to avoid the first corner, better preventing motion interference between the first corner and the side wall 212 of the first groove, thereby making the removal process of the fixing strap 100 smoother.
[0121] As shown in Figure 13, the connecting surface 1213 includes a first connecting surface end 1213a located near the protrusion 122 and a second connecting surface end 1213b located away from the protrusion 122. The second connecting surface end 1213b deviates from the first connecting surface end 1213a in a direction closer to the second end 121b, so that the width of the clearance gap 400 gradually increases along the first direction X+.
[0122] In some embodiments, as shown in Figures 13 and 15, a rounded corner 1214 is provided between the back surface 1212 and the connecting surface 1213. By providing the rounded corner 1214, the sharp corner formed between the back surface 1212 and the connecting surface 1213 can be 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 snap-fit member 120 around the rotating shaft 123, thereby reducing the probability of surface damage to the belt body 110 and the first groove sidewall 212.
[0123] To facilitate the movement of the main body 121 of the latching component to the unlocked position, as shown in FIG12a, the latching component 120 further includes a pressing part 124, which is connected to the second end 121b of the main body 121 of the latching component. When the pressing part 124 is pressed, the latching component 120 moves to the unlocked position.
[0124] As shown in Figure 12a, the pressing part 124 and the snap-fit body 121 can be an integral structure, but it is not limited to this. The pressing part 124 can also be set separately from the snap-fit body 121.
[0125] In some embodiments, as shown in FIG12a, an anti-slip structure 1242 is provided on the pressing surface 1241 of the pressing part 124. With this configuration, when the pressing part 124 is pressed by a finger, the anti-slip structure 1242 can prevent the finger from sliding between the finger and the pressing surface 1241 of the pressing part 124, thereby facilitating the pressing part 24 to be pressed down.
[0126] The anti-slip structure 1242 is not unique. For example, as shown in Figure 12a, the anti-slip structure 1242 can be an anti-slip groove. The extending direction of the anti-slip groove can be parallel to the rotating shaft 123, or it can form a certain angle with the rotating shaft 123. No specific limitation is made here. For another example, the anti-slip structure 1242 can also be an anti-slip protrusion.
[0127] During the use of wearable devices, the strap 110 is inevitably subjected to external pulling forces. When it is pulled, the tension on the strap 110 is transmitted to the snap fastener 120 through the pivot 123. The snap fastener 120 tends to move outward from the first slot 210. In order to prevent the snap fastener 120 from being pulled out of the first slot 210 under external force, in some embodiments, as shown in FIG12a, the pivot 123 is disposed at the first end 121a of the snap fastener body 121.
[0128] This arrangement allows the pivot 123 to be positioned close to the protrusion 122. Specifically, when the belt 110 is pulled by an external force, the force point of the locking member 120 is located at the first end 121a (i.e., the position of the pivot 123). Since the degree of freedom of the protrusion 122 at the first end 121a is restricted by the second slot 220, the locking member body 121 is less likely to disengage from the first slot 210 when the belt 110 is pulled by an external force, thus ensuring the reliability of the connection between the fixing strap 100 and the equipment body 200. Furthermore, the pivot 123 being positioned at the first end 121a increases the length of the lever arm of the pressing part 124, making the pressing part 124 more effortless to press.
[0129] In some embodiments, as shown in FIG12a, 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 configuration allows the second end 121b of the snap fastener body 121 to easily move out of the first snap groove 210 from the second groove sidewall 213 during the removal of the fixing strap 100, i.e., during the rotation of the snap fastener 120 towards the unlock position, thus making the removal of the fixing strap 100 smoother.
[0130] In some embodiments, as shown in Figures 12a and 16, Figure 16 is a partially enlarged view of the wearable device shown in Figure 12a at the second groove sidewall 213. The inner surface 2131 of the second groove sidewall 213 is inclined relative to the groove depth direction of the first slot 210, and the inner surface 2131 of the second groove sidewall 213 is inclined away from the first groove sidewall 212. With this configuration, during the installation of the fixing strap 100 on the device body 200, the inner surface 2131 of the second groove sidewall 213 can guide the snap-fit body 121. As shown in Figure 12b, when the second end 121b of the snap-fit body 121 is located at the opening of the first slot 210, the second end 121b of the snap-fit body 121 can enter the first slot 210 along the inner surface 2131 of the second groove sidewall 213, as shown in Figure 12a, thereby snapping the fixing strap 100 into the device body 200.
[0131] As shown in Figures 12a and 16, the inner surface 2131 of the second groove sidewall 213 is inclined away from the first groove sidewall 212. Specifically, the inner surface 2131 of the second groove sidewall 213 includes a near end 2131a near the bottom wall 211 of the groove and a far end 2131b away from the bottom wall 211 of the groove. The far end 2131b is offset from the near end 2131a to the side away from the first groove sidewall 212 (that is, the lower side shown in the figure).
[0132] In some embodiments, as shown in FIG12a, the wearable device further includes a magnetic suction component 500, which is disposed on at least one of the device body 200 and the card holder body 121 (the magnetic suction component 500 is disposed on both the device body 200 and the card holder body 121 in the figure). The magnetic suction component 500 is used to apply a magnetic force to the card holder body 121, which can cause the card holder body 121 to move towards the bottom wall 211 of the slot. With this configuration, the magnetic suction component 500 can magnetically position the card holder body 121 of the fixing strap 100 during the installation process, thereby facilitating the insertion of the card holder body 121 into the first card slot 210.
[0133] In some embodiments, as shown in FIG12a, the magnetic suction component 500 includes a first magnetic suction component 510 and a second magnetic suction component 520. The first magnetic suction component 510 is disposed at a position on the device body 200 corresponding to the bottom wall 211 of the groove. The second magnetic suction component 520 is disposed on the snap-fit body 121 and is disposed on the side of the rotating shaft 123 near the second end 121b of the snap-fit body 121. Magnetic attraction can be generated between the first magnetic suction component 510 and the second magnetic suction component 520. Both the first magnetic suction component 510 and the second magnetic suction component 520 can be magnets.
[0134] Because the first magnetic 510 and the second magnetic 520 have magnetic alignment, when the main body 121 of the fastener approaches the main body 200, under the magnetic attraction of the first magnetic 510 and the second magnetic 520, one end of the fastener 120 of the fixing strap 100 can automatically attract and engage with the main 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.
[0135] The following describes in detail the process by which the fixing strap 100 automatically attracts and engages with the main body of the device 200 under the action of magnetic attraction:
[0136] As shown in Figure 12e, firstly, the fixing strap 100 has one end of the latching member 120 close to the first slot 210 of the device body 200. As shown in Figure 12c, under the magnetic attraction between the first magnetic member 510 and the second magnetic member 520, the latching member 120 moves towards the bottom wall 211 of the first slot 210, and the contact surface 1211 of the latching member 120 abuts against the side wall 213 of the second slot. At the same time, the first end 121a of the latching member 120 extends into the first slot 210 and abuts against the bottom wall 211. At this time, the latching member 120 is in the unlocked position, and the protrusion 122 is opposite to the opening of the second slot 220. As shown in Figures 12c and 12b, due to the magnetic alignment between the first magnetic member 510 and the second magnetic member 520, the latching member body 121 is subjected to a magnetic attraction towards the upper left. Under the action of the magnetic attraction, the main body 121 of the snap fastener moves upward so that the second end 121b of the main body 121 is located at the opening of the first slot 210. Since the inner surface 2131 of the second slot sidewall 213 is inclined relative to the depth direction of the first slot 210, under the action of the magnetic attraction, as shown in Figures 12b and 12a, the second end 121b of the snap fastener 121 enters the first slot 210 along the inner surface 2131 of the second slot sidewall 213, so that the contact surface 1211 of the snap fastener 120 abuts against the bottom wall 211 of the slot, and the protrusion 122 extends into the second slot 220, thereby realizing the snap fastening between the fixing strap 100 and the device body 200.
[0137] In some embodiments, as shown in FIG5, the device body 200 has a first receiving groove 231 at a position corresponding to the bottom wall 211 of the groove, and the first magnetic suction member 510 is disposed in the first receiving groove 231. A first protective cover plate 232 is provided at the opening of the first receiving groove 231, and the first protective cover plate 232 covers the first magnetic suction member 510. In this configuration, the first protective cover plate 232 can protect the first magnetic suction member 510 in the first receiving groove 231 and prevent the first magnetic suction member 510 from contacting other components and being damaged.
[0138] As shown in Figures 5 and 6, the first receiving groove 231 is disposed on the housing 250 of the main body 200 of the equipment. Further, the first receiving groove 231 is disposed on the middle frame 251.
[0139] In some embodiments, as shown in FIG8, the snap-fit body 121 is provided with a second receiving groove 1215, and the second magnetic member 520 is disposed in the second receiving groove 1215. A second protective cover plate 1216 is provided at the opening of the second receiving groove 1215, and the second protective cover plate 1216 covers the second magnetic member 520. In this configuration, the second protective cover plate 1216 can protect the second magnetic member 520 in the second receiving groove 1215, and prevent the second magnetic member 520 from contacting other components and being damaged.
[0140] As shown in Figure 8, the second receiving groove 1215 is disposed on the back side 1212 of the snap-fit body 121, thereby preventing the second receiving groove 1215 from being disposed on the abutment surface 1211.
[0141] In this embodiment of the application, the magnetic component 500 may also include only the first magnetic component 510, and the snap-fit component 120 may be made of magnetic material, so that magnetic attraction can also be generated between the first magnetic component 510 and the snap-fit component 120.
[0142] In the wearable device of this application embodiment, the magnetic component 500 can also be replaced with an elastic component. The elastic component is connected to the snap fastener 120. The elastic component is used to apply an elastic force to the snap fastener 120 to move towards the locking position. In this way, under the action of the elastic force, the snap fastener 120 can maintain contact with the bottom wall 211 of the first slot 210, which helps to improve the connection reliability between the fixing strap 100 and the device body 200.
[0143] The specific type of elastic component is not unique. For example, the elastic component can be a spring, which is connected between the groove wall of the latching member receiving groove 114 and the pressing part 124 of the latching member 120. When the latching member 120 is in the unlocked position, the spring is in a compressed state. Alternatively, the elastic component can 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 latching member receiving groove 114, and the other connecting arm of the torsion spring abuts against the latching member body 121. When the latching member 120 is in the unlocked position, the torsion spring is in a charged state.
[0144] It should be noted that the above embodiment is illustrated by taking the first slot 210 on the housing 250 and the snap fastener 120 on the fixing strap 100 as an example. It can be understood that the snap fastener 120 can also be provided on the housing 250 and the first slot 210 can be provided on the fixing strap 100.
