Description

Technical Field

[0001] The present application relates to the field of electronic devices, and in particular to a wearable device. Background Art

[0002] In daily life, users have the need to replace the strap of a wearable device according to different requirements. Therefore, in order to meet the need for strap replacement, the strap of the wearable device needs to be detachable.

[0003] Therefore, how to provide a wearable device and realize detachable connection of the fixing strap of the wearable device is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] The present application provides a wearable device, which realizes a detachable connection of a fixing strap of the wearable device.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0006] In the first aspect, the present application provides a wearable device, comprising: a host, the host comprising a middle frame and a base connected to one side of the middle frame; the middle frame having a mounting slot and a snap-in hole, the mounting slot extending along a first direction, the snap-in hole being arranged on the slot wall of the mounting slot close to the base, the snap-in hole being a through hole extending along a second direction, the second direction intersecting with the first direction, and the second direction being the connecting direction of the middle frame and the base; the base having a base mounting hole extending along the second direction, the base mounting hole being opposite to and connected to the snap-in hole; a fixing strap, the fixing strap being installed with a snap-in assembly, the snap-in assembly comprising a shell and a snap-in part, the snap-in part being located in the shell and capable of extending out of the shell along the second direction; the fixing strap being inserted into the mounting slot along the first direction, and the snap-in part being capable of snapping into the snap-in hole; a button assembly, the button assembly comprising a button, the button being installed in the base mounting hole, and being capable of moving along the base mounting hole to extend into the snap-in hole, abutting against the snap-in part, and pushing the snap-in part out of the snap-in hole.

[0007] It can be seen from the above content that: an installation slot along the first direction and a snap-in hole passing through the second direction are set on the middle frame of the host, the fixing belt can be inserted into the installation slot, and the snap-in part of the snap-in assembly on the fixing belt can be snapped into the snap-in hole to realize the fixed connection between the fixing belt and the host; and the button of the button assembly on the base of the host can be extended into the snap-in hole and push the snap-in part out of the snap-in hole to realize the disassembly of the fixing belt, which is convenient for the operator to replace the fixing belt and meet the replacement needs of the fixing belt.

[0008] In one possible embodiment, the snap-on assembly further includes: a first limiting member, the first limiting member is connected to a side of the snap-on member away from the protruding shell, and the first limiting member protrudes toward the side of the snap-on member; a first elastic member, the first elastic member abuts between the bottom surface of the shell and the first limiting member; a driving member, the driving member is movably installed in the shell, and the driving member can extend outward from the top surface of the shell; a second elastic member, the second elastic member abuts between the driving member and the snap-on member, and when the first elastic member and the second elastic member are at an initial length, the upper section of the driving member extends outward from the shell, and the snap-on member is retracted into the shell.

[0009] From the above content, it can be seen that when the clamping assembly is in the initial state, the clamping part is retracted into the shell and the driving part is extended out of the shell, which protects the safety of the clamping part and prevents damage from collision. During the assembly process of the fixing belt and the host, the driving part can be used to share the wear and reduce the wear of the clamping part.

[0010] In a possible implementation manner, there are at least two first limiting members, which are distributed on both sides of the clamping member, and the second elastic member is located between the first elastic members on both sides of the clamping member.

[0011] It can be seen from the above content that: the first limit and the first elastic member are set on both sides of the clamping member, which can ensure the stability of the clamping member during the extension and contraction process, avoid tilting, and cause jamming; the second elastic member is located between the first elastic member, so that the first elastic member and the second elastic member are staggered, reducing the thickness of the clamping assembly.

[0012] In a possible implementation, the first limiting member and the clamping member are integrally formed, and the wear resistance of the driving member is higher than that of the clamping member.

[0013] From the above, it can be seen that one-piece molding can simplify installation and ensure connection strength; it increases the wear resistance of the drive parts and prolongs their service life.

[0014] In a possible embodiment, the side of the driving member away from the clamping member is the upper end surface, and the distance from the upper end surface to the clamping member gradually increases from the edge of the upper end surface to the center of the upper end surface.

[0015] From the above content, it can be seen that setting the upper end surface of the driving part as an inclined surface is beneficial to the process of inserting the fixing belt into the installation groove, in which the edge of the driving part first rubs against the side wall of the installation groove, and at this time the clip has not extended out of the shell, thereby reducing the contact distance between the clip and the installation groove, thereby reducing the wear of the clip.

[0016] In a possible implementation manner, the upper end surface of the driving member is an arc surface.

[0017] It can be seen from the above content that the arc surface can reduce the wear of the driving member and the side wall of the installation groove.

[0018] In one possible embodiment, the snap-on assembly further includes: a first limiting member, the first limiting member is connected to a side of the snap-on member away from the protruding shell, and the first limiting member protrudes toward the side of the snap-on member; a first elastic member, the first elastic member abuts between the top surface of the shell and the first limiting member, and when the first elastic member is at its length, the snap-on member protrudes out of the shell.

[0019] From the above, it can be seen that when the first elastic member is at its initial length, the clamping member extends outward from the housing, and when the first elastic member is squeezed, the clamping member retracts into the housing. This structure is simple, has low processing cost, and is easy to assemble.

[0020] In a possible embodiment, the housing includes: a first shell and a second shell, the first shell and the second shell are spliced ​​together, and a connection seam between the first shell and the second shell is located on a side and / or bottom surface of the housing.

[0021] From the above, it can be seen that the shell is spliced ​​to facilitate the disassembly and assembly of the internal structure; and the connecting seams of the shell are located on the side and / or bottom surface, which can ensure the integrity of the fixing belt surface and facilitate the sealing of the snap-on assembly.

[0022] In one possible embodiment, the button assembly further includes: a third elastic member, the button is installed in the base mounting hole through the third elastic member, and when the third elastic member is at an initial length, the first end of the button is exposed on the side of the base away from the middle frame, and the first end of the button is subjected to force, and in the process of squeezing the third elastic member, the second end of the button extends into the snap-fit ​​hole and is used to push the snap-fit ​​member.

[0023] It can be seen from the above content that by providing the third elastic member, the key can be automatically reset and the key can be prevented from shaking in the base mounting hole.

[0024] In one possible embodiment, the button assembly further includes: a limiting structure, which is used to limit the upper and lower stop points of the button's movement in the base mounting hole, and when the button moves to the upper stop point, the first end of the button pushes the clip out of the clip hole; when the button moves to the lower stop point, the first end of the button is retracted into the base mounting hole or extends into the clip hole a preset distance, and the second end of the button is exposed on the base.

[0025] From the above content, it can be seen that by setting a limit structure, the movement of the button in the base mounting hole is limited, ensuring that the movement distance of the button can complete the pushing of the clamping part out of the clamping hole and can ensure that the user can easily operate the button.

[0026] In one possible embodiment, the limiting structure includes: an assembly rod, which is installed in the base mounting hole along the first direction; the button has an adjustment hole extending along the second direction, the assembly rod is inserted into the adjustment hole, and when the assembly rod abuts against the upper end surface of the adjustment hole along the second direction, the button is located at the bottom stop point; when the assembly rod abuts against the lower end surface of the adjustment hole along the second direction, the button is located at the bottom stop point.

[0027] From the above content, it can be seen that the upper and lower stop points of the key are limited by the combination of the assembly rod and the adjustment hole, which has a simple structure and is easy to operate. In addition, during operation, the adjustment hole can also guide the movement of the key.

[0028] In one possible embodiment, the button includes: a thrust portion, which can extend into the snap-fit ​​hole and abut against the snap-fit ​​part, and the thrust portion has an adjustment hole; a pressing portion, the thrust portion and the pressing portion are connected along the second direction to form the second end and the first end of the button respectively, the thrust portion is fixedly connected to the first side of the pressing portion, and the pressing portion can extend outward from the base; a third elastic member abuts against the first side of the pressing portion and is distributed on both sides of the thrust portion.

[0029] From the above content, it can be seen that the width of the thrust portion is smaller than the width of the pressing portion, which can reduce the size of the clamping hole and is conducive to the miniaturization of the host; the third elastic member can limit the movement distance of the button and prevent the button from detaching from the base mounting hole.

[0030] In one possible embodiment, the limiting structure includes: a second limiting member, which is fixed to the side wall of the base mounting hole; a lap joint, which is connected to the button, and a U-shaped groove structure with an opening toward the side wall of the base mounting hole is formed between the lap joint and the button, and the second limiting member extends into the U-shaped groove structure. When the second limiting member and the lap joint are against each other, the button is located at the lower stop point; when the second limiting member and the button are against each other, the button is located at the upper stop point.

[0031] It can be seen from the above content that the second limiting member and the key form a U-shaped groove structure, and the U-shaped groove structure and the second limiting member are used to limit the moving position of the key, and the matching accuracy requirement is low.

[0032] In a possible embodiment, the side wall of the base mounting hole has an accommodating groove, the second limiting member is a U-shaped elastic clip, and the U-shaped elastic clip abuts between two side walls of the accommodating groove.

[0033] It can be seen from the above content that the installation of the second limiting member is simplified by using the elastic contact between the two side walls of the accommodating groove due to the elasticity of the U-shaped elastic clamp.

[0034] In one possible embodiment, there are two bridging members, namely a first bridging member and a second bridging member, and they are distributed on both sides of the button, wherein the second limiting member extends into the first bridging member; when the first bridging member and the second limiting member abut against each other, the second bridging member abuts against the step surface of the side wall of the base mounting hole.

[0035] It can be seen from the above content that the first connecting piece and the second limiting piece cooperate to achieve the limitation of the key, and the second connecting piece and the step surface of the base mounting hole are offset to achieve the limitation of the key, preventing the key from shifting when it is at the bottom dead point, ensuring the stability of the key during movement, and preventing the key from getting stuck.

[0036] In one possible embodiment, the button includes: a thrust portion, which can be extended into the snap-on hole and abut against the snap-on member; a pressing portion, which is connected to the pressing portion along the second direction to form the second end and the first end of the button respectively, and the thrust portion is fixedly connected to the first side of the pressing portion, and the pressing portion can extend outward from the base; a third elastic member abuts against the first side of the pressing portion and is distributed on both sides of the thrust portion, the lap member is an L-shaped plate, the first plate of the lap member is installed at the end of the pressing portion, and the second plate of the lap member is opposite to the pressing portion, and forms a U-shaped groove structure.

[0037] From the above content, it can be seen that the width of the thrust portion is smaller than the width of the pressing portion, which can reduce the size of the clamping hole and is conducive to the miniaturization of the host; the third elastic member can limit the movement distance of the button and prevent the button from detaching from the base mounting hole.

[0038] In a possible embodiment, the fixing belt is integrally formed with the housing of the snap-fit ​​assembly or is detachably fixedly connected thereto.

[0039] From the above content, it can be seen that the fixing belt and the shell of the clip-on assembly are integrally formed, which can simplify the structure, improve assembly efficiency, and ensure the connection strength; the fixing belt and the clip-on assembly are detachably fixedly connected, which facilitates the replacement and maintenance of the structure inside the shell and reduces maintenance costs.

[0040] In a possible embodiment, the clamping assembly has a connecting post, and the fixing belt has a connecting hole for inserting the connecting post.

[0041] It can be seen from the above content that the connection method using the connection column and the connection hole is applicable to the weaving of the fixing belt, thereby increasing the range of the fixing belt that can be used.

[0042] In one possible embodiment, the housing has a watch lug for connecting to a fixing strap.

[0043] From the above, it can be seen that the provision of lugs on the housing facilitates connection with existing standard fixing straps, further increasing the range of usable fixing straps.

[0044] In one possible implementation, the wearable device is a wristwatch.

[0045] It can be seen from the above content that when the wearable device is a wristwatch, the fixing strap is a watch strap. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Wearable devices include, but are not limited to, watches (also known as wristwatches), bracelets, finger rings, health monitoring devices, or medical devices. Wearable devices typically consist of a host device and a fixed strap. The host device is the main structure that implements the function, and the fixed strap is connected to the host device and can be worn by the user.

[0077] As used herein, the terms "include", "comprising", "having" and variations thereof mean "including but not limited to", unless specifically emphasized otherwise.

[0078] The following Figure 1 Taking the watch 01000 shown in the example, the structure of the wearable device is explained.

[0079] Figure 1 The watch 01000 includes: a main unit 01 and a watch strap 02.

[0080] Host 01 serves as the host structure and can be used to display the time. For smartwatches, host 01 can also display health indicators (such as blood pressure, heart rate, blood oxygen, and blood sugar). Strap 02 is connected to host 01 and can be worn by the user or integrated into the user's clothing or accessories.

[0081] In some embodiments, the strap 02 includes but is not limited to a ring-shaped strap connected to both ends of the host 01 or a strip-shaped strap distributed at both ends of the host 01.

[0082] Reference to "some embodiments" in this specification means that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present application. The phrase "in other embodiments" appearing in various places in this specification does not necessarily refer to the same embodiment, but rather means "one or more, but not all, embodiments," unless otherwise specifically stated.

[0083] In daily life, users may need to choose watchbands 02 of different materials or shapes according to different seasons, different moods, different clothing, etc. In addition, users may also need to choose a more comfortable watchband 02 according to different usage scenarios, such as wearing a waterproof watchband for swimming, or a nylon watchband for improved breathability during exercise. If the watchband 02 also carries the function of monitoring health indicators, such as blood pressure, blood oxygen, or blood sugar, users may also need to change the watchband 02 according to their specific monitoring requirements.

[0084] Based on the need to replace strap 02, Figure 2 The watch band 2 of the watch 1000 disclosed in the specification is detachably connected to the host 1.

[0085] The following combination Figure 2 The assembly relationship of the watch 1000 shown in the figure is used to illustrate the structure of the watch 1000 disclosed in this application.

[0086] Figure 2 The watch 1000 includes a host 1, a watch band 2 and a connecting component 3. The watch 1000 realizes a detachable connection between the watch band 2 and the host 1 through the connecting component 3.

[0087] Among them, the host 1 includes but is not limited to being used to display time and health indicators (such as blood pressure, heart rate, blood oxygen, blood sugar, etc.). It should be noted that the content displayed by the host 1 can also be set according to different needs and is within the protection range.

[0088] The strap 2 is a structure worn by the user, or integrated into the user's clothing or accessories, and includes but is not limited to a ring-shaped strap connected to both ends of the host 1 or a strip-shaped strap distributed at both ends of the host 1. It should be noted that the shape, size, and material of the strap 2 are not specifically limited in this application.

[0089] In some embodiments, the host 1 has a mounting slot 121 , and the strap 2 can be inserted into the mounting slot 121 .

[0090] The connecting assembly 3 includes a snap-on assembly 31 and a button assembly 32 .

[0091] The snap-on assembly 31 is connected to the strap 2. In some embodiments, the snap-on assembly 31 is connected to the end of the strap 2 to form a head. The button assembly 32 is connected to the host 1. After the strap 2 is inserted into the mounting slot 121, the snap-on assembly 31 can be snapped into the mounting slot 121 to secure the strap 2 to the host 1. Pressing the button assembly 32 releases the snap-on assembly 31 from the mounting slot 121, separating the strap 2 from the host 1.

[0092] It should be noted that the shapes and sizes of the host 1 and the strap 2 can be set according to different needs. The structures of the host 1 and the strap 2 are described in detail below.

[0093] The above content describes the connection method between the main unit 1 and the strap 2 of the watch 1000. Figures 3 to 7 A structure and connection method of the connection component 3 are described. Figure 3 This is a diagram of the first connection relationship between the watch strap and the snap-on assembly 31.

[0094] like Figure 3 The watchband 2 shown in the figure has a connecting slot 21 at one end. The connecting slot 21 extends through the thickness of the watchband 2, and the width of the slot opening is less than the distance between the two side edges of the connecting slot 21. In some embodiments, the side edges of the connecting slot 21 are curved sidewalls, and the two side edges protrude away from each other, forming a waist-shaped groove with a slot opening at the end surface. It should be noted that the width of the slot opening refers to the width dimension of the watchband 2, and the two side edges refer to the two widthwise edges of the watchband 2.

[0095] The thickness direction of the strap 2 herein is the second direction.

[0096] The outer contour of the snap-fit ​​assembly 31 is a shape that matches the connection slot 21, and the snap-fit ​​assembly 31 can be snapped into the connection slot 21 to achieve the connection between the snap-fit ​​assembly 31 and the watchband 2. The connection between the snap-fit ​​assembly 31 and the watchband 2 includes but is not limited to an integral molding or a post-assembly fixed connection.

[0097] It should be noted that the connection groove 21 can also be a groove of other shapes, including but not limited to: a trapezoidal groove with a groove width smaller than the groove bottom width. The connection method between the strap 2 and the clamping assembly 31 can also be adhesive or threaded connection.

[0098] In some embodiments, the snap-fit ​​assembly 31 and the watch strap 2 may be injection molded, or a plastic wrap may be added to the snap-fit ​​assembly 31 to ensure a secure connection between the snap-fit ​​assembly 31 and the watch strap 2 .

[0099] The above discloses a connection method between the snap-on assembly 31 and the strap 2. Figure 4 The structure of the clamping assembly 31 is described. Figure 43 is a connection diagram of the first structure of the snap-fit ​​assembly 31.

[0100] Figure 4 The snap-on assembly 31 shown in FIG. 3 includes a housing 311 and a telescopic assembly 312 .

[0101] The housing 311 has an interior containing a cavity, and the telescopic assembly 312 is located in the cavity.

[0102] The housing 311 includes a first shell 3111 and a second shell 3112 .

[0103] It should be noted that the words "first", "second", "third", etc. in the description of this article are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0104] The first shell 3111 has a first bonding groove 31114, and the second shell 3112 has a second bonding groove (not shown in the figure) opposite to the first bonding groove 31114. The first shell 3111 and the second shell 3112 are fixedly connected by injecting or dispensing glue in the first bonding groove 31114 and the second bonding groove.

[0105] The shapes and sizes of the first bonding groove 31114 and the second bonding groove are not specifically limited here. Optionally, the first bonding groove 31114 and the second bonding groove are respectively opened at the edges of the first shell 3111 and the second shell 3112.

[0106] It should be noted that the fixed connection between the first shell 3111 and the second shell 3112 includes, but is not limited to, snap-fitting, gluing, or threading the first shell 3111 and the second shell 3112. In some embodiments, the housing 311 includes, but is not limited to, being divided into the first shell 3111 and the second shell 3112. The housing 311 can also be divided into three or more parts as needed, as long as they are spliced ​​and connected to form a housing 311 that can be matched with the connection slot 21.

[0107] The housing 311 is formed by splicing a first shell 3111 and a second shell 3112 , which facilitates assembly and disassembly of the clamping member 3121 , the first limiting member 3122 and the first spring 3123 inside the housing 311 .

[0108] In some embodiments, the first shell 3111 and the second shell 3112 are sealed to ensure waterproof and dustproof performance at the connection seam between the two.

[0109] In some embodiments, the first housing 3111 includes a top plate 31111, a first curved side plate (not shown) arranged circumferentially around the top plate 31111, a panel 31112, and a first bottom plate (not shown). The top plate 31111 is a waist-shaped plate adapted to fit within the connection groove 21, and the first curved side plate has a first bonding groove 31114. The second housing 3112 includes a back plate 31121, a second curved side plate 31122, and a second bottom plate (not shown). The second curved side plate 31122 has a second bonding groove.

[0110] During the docking process between the first shell 3111 and the second shell 3112, the first curved side panel and the second curved side panel 31122 are connected to form the side panels of the outer shell 311, the first bottom panel of the first shell 3111 and the second bottom panel of the second shell 3112 are spliced ​​to form the bottom panel of the outer shell 311, the top panel 31111 is the top panel of the outer shell 311, the back panel 31121 is the back panel of the outer shell 311, and the panel 31112 is the panel of the outer shell 311, and a accommodating cavity is formed between the top panel 31111, the back panel 31121, the side panel, the bottom panel and the panel 31112.

[0111] Since the second shell 3112 does not have a top plate and is the circumferential surface of the outer shell 311 , after the first shell 3111 and the second shell 3112 are spliced ​​together, the connection seam between the first shell 3111 and the second shell 3112 is located at the side plate and the back plate of the outer shell 311 .

[0112] By adopting the structure of the above-mentioned shell 311, during the assembly process of the snap-on assembly 31 and the strap 2, the back plate 31121 of the second shell 3112 fits against the bottom of the connecting groove 21 of the strap 2, which can ensure that the connecting seams of the shell 311 can be wrapped by the connecting groove 21, thereby further ensuring the sealing of the shell 311.

[0113] In some embodiments, the first bottom plate of the first housing 3111 or the second bottom plate of the second housing 3112 has a first mounting hole 31113, or the first mounting hole 31113 is formed at the junction of the first bottom plate of the first housing 3111 and the second bottom plate of the second housing 3112. In some embodiments, the first mounting hole 31113 includes, but is not limited to, a circular hole, a waist-shaped hole, and a rectangular hole.

[0114] It should be noted that the shapes of the first shell 3111 and the second shell 3112 include but are not limited to the above-disclosed contents, and the first shell 3111 and the second shell 3112 can also be set to a symmetrical structure according to different needs.

[0115] It is defined herein that during the connection between the strap 2 and the host 1 , the connection direction between the top plate 31111 and the bottom plate of the housing 311 is the second direction, and the first mounting hole 31113 passes through the bottom plate of the housing 311 along the second direction.

[0116] The above content describes the structure, shape and connection method of the housing 311. Figure 4 The structure and connection relationship of the telescopic component 312 are described as follows:

[0117] Figure 4 The telescopic assembly 312 includes a clamping member 3121 , a first limiting member 3122 and a first spring 3123 .

[0118] Among them, the clamping member 3121 is located in the first mounting hole 31113, and can move along the through direction of the first mounting hole 31113 to extend outward from the shell 311, and the extending length of the clamping member 3121 can be set according to different needs; the first limiting member 3122 is fixedly connected to the clamping member 3121, including but not limited to integral molding, to limit the movement of the clamping member 3121; the first spring 3123 is installed between the clamping member 3121 and the top plate 31111, and can be extended and retracted.

[0119] In some embodiments, the clamping member 3121 has the same shape as the first mounting hole 31113. In order to reduce the gap between the clamping member 3121 and the first mounting hole 31113 and ensure that the two can move relative to each other, in some embodiments, the clamping member 3121 and the first mounting hole 31113 are clearance-matched.

[0120] A step structure is formed at the connection between the first limiting member 3122 and the clamping member 3121 , and the step structure can be clamped and limited at the edge of the first mounting hole 31113 of the bottom plate of the housing 311 .

[0121] In some embodiments, the first limiting member 3122 is an L-shaped structure, including a first section and a second section connected to form an L-shape.

[0122] Among them, the first section of the first limiting member 3122 is fixedly connected to the side of the clamping member 3121 facing the top plate 31111, and the connection between the first section and the clamping member 3121 forms a step structure, and the first section is exposed to the outer contour of the clamping member 3121; the second section of the first limiting member 3122 faces the side of the shell 311, and the first spring 3123 is against the second section and the top plate 31111.

[0123] When the first spring 3123 is at its initial length, the engaging member 3121 extends out of the housing 311 through the first mounting hole 31113, and the stepped structure of the first limiting member 3122 abuts against the edge of the first mounting hole 31113. In some embodiments, the initial length of the first spring 3123 can be a compressed state or a free state.

[0124] When the clamping member 3121 is forced to move toward the inside of the housing 311 , the first spring 3123 will be compressed; after the external force is removed, the clamping member 3121 can be extended out of the housing 311 under the action of the first spring 3123 .

[0125] In some embodiments, there are two first limiting members 3122 disposed at both ends of the clamping member 3121 , and there are two first springs 3123 corresponding one-to-one to the first limiting members 3122 , so that the telescopic assembly 312 forms a symmetrical structure.

[0126] The first limit member 3122 of the telescopic assembly 312 disclosed in the above embodiment can limit the outward extension length of the clamping member 3121, and the first spring 3123 can realize the automatic reset of the clamping member 3121. The provision of two first limit members 3122 and two first springs 3123 can improve the stability of the clamping member 3121 during the telescopic process.

[0127] In some embodiments, the first position-limiting member 3122 may not limit the clamping member 3121 but may only be used to connect the first spring 3123 . The moving distance of the clamping member 3121 may be set by the spring force of the first spring 3123 .

[0128] It should be noted that in some embodiments, other elastic structural parts can be used to replace the first spring 3123. Therefore, only elastic parts that can complete the function of the above-mentioned first spring 3123 are within the protection range, that is, the first elastic part includes but is not limited to the first spring 3123.

[0129] The above content is a description of a specific structure of the clamping assembly 31. Figure 5 and Figure 6 The structure of the key assembly 32 is described, wherein: Figure 5 This is the connection diagram of the structure of host 1. Figure 6 This is a partial cross-sectional view of the base. Figure 7 This is a diagram of the assembly relationship between the button assembly 32 and the host.

[0130] like Figure 5 As shown, the host 1 includes: an upper cover 11 , a middle frame 12 and a base 13 .

[0131] Herein, the upper cover 11 , the middle frame 12 and the base 13 are sequentially arranged along the second direction to form the thickness direction of the host 1 .

[0132] The upper cover 11 is detachably and sealedly connected to the upper surface of the middle frame 12, and the base 13 is detachably and sealedly connected to the lower surface of the middle frame 12. In some embodiments, the base 13 has a mounting groove 131, into which the lower surface of the middle frame 12 is mounted. The connection methods between the upper cover 11 and the middle frame 12 include, but are not limited to, snap-fitting or bonding, and the connection methods between the middle frame 12 and the base 13 include, but are not limited to, snap-fitting or threaded connection.

[0133] In some embodiments, the upper cover 11 is a transparent lens, including but not limited to quartz glass or synthetic sapphire glass. The middle frame 12 may contain components of a mechanical watch, electronic watch, or testing equipment. The user can observe the components in the middle frame 12 through the upper cover 11. The materials of the middle frame 12 and the base 13 can be set according to different needs and are all within the protection range.

[0134] If the host 1 is an intelligent structure, the upper cover 11 can also be a display screen or a touch screen, and the middle frame 12 can be provided with components such as a circuit board electrically connected to the display screen or touch screen. The user can directly observe the upper cover 11 or touch the upper cover 11 to complete observation or operation.

[0135] In some embodiments, the middle frame 12 has a mounting slot 121 and a snap-in hole 122 .

[0136] The mounting slot 121 is used to mount the snap-fit ​​assembly 31 on the watchband 2. Therefore, in some embodiments, the shape of the mounting slot 121 is the same as the shape of the end of the watchband 2 having the snap-fit ​​assembly 31, and the two can be loosely matched to ensure that the watchband 2 can be inserted into the mounting slot 121. The snap-fit ​​hole 122 is connected to the mounting slot 121 and is formed on the side wall of the mounting slot 121 near the base 13. The snap-fit ​​hole 122 is a through hole along the thickness direction of the middle frame 12. Figure 4 After the clamping assembly 31 is installed into the installation slot 121 , the clamping member 3121 of the clamping assembly 31 can extend into the clamping hole 122 .

[0137] Combine Figure 8 As shown, the mounting slot 121 has only one slot, and the slot is a waist-shaped slot. The mounting slot 121 extends along the first direction of the middle frame 12, and the watch strap 2 is inserted into the mounting slot 121 along the first direction.

[0138] The first direction is the direction of the line connecting the slot opening and the slot bottom of the installation slot 121. The engaging hole 122 passes through the middle frame 12 along the second direction, and the first direction and the second direction intersect.

[0139] The shape of the clamping hole 122 can be set according to different needs. Figure 5 The clamping hole 122 shown in FIG is a waist-shaped hole, and can be matched with the clamping member 3121. The cross-sectional dimension of the clamping hole 122 is smaller than the cross-sectional dimension of the mounting groove 121.

[0140] It should be noted that the distance the clip 3121 extends into the clip hole 122 defines the effective mating area for the connection between the watchband 2 and the main unit 1. To prevent the watchband 2 from dislodging from the mounting slot 121 under certain external forces, the effective mating area between the clip 3121 and the clip hole 122 must meet certain requirements. Therefore, within the limited thickness of the main unit 1, ensuring sufficient overlap between the clip 3121 and the clip hole 122 and preventing it from dislodging under tension will constrain the space available for the rounded end of the clip 3121 (e.g., the fillet radius).

[0141] It should be noted that the size of the effective matching area between the clamping member 3121 and the clamping hole 122 can be adjusted according to the material of the clamping member 3121 and is not specifically limited here.

[0142] When the watchband 2 is inserted into the mounting slot 121, the clip 3121 will generate friction with the wall of the mounting slot 121. To reduce this friction, it is generally necessary to reduce the contact area between the clip 3121 and the wall of the mounting slot 121, including but not limited to chamfering or rounding the corners of the clip 3121. Based on the above analysis, the size and edge shape of the clip 3121 can be adjusted according to different needs.

[0143] like Figure 5 and Figure 6 In the illustrated embodiment, the base 13 has a third mounting hole 132 and an assembly hole 133 .

[0144] The third mounting hole 132 is a through hole that passes through the base 13. In some embodiments, the third mounting hole 132 passes through the thickness direction of the base 13. The third mounting hole 132 can be defined as a base mounting hole.

[0145] The thickness direction of the base 13 is the second direction.

[0146] The assembly hole 133 is connected to the third assembly hole 132, and the axis of the assembly hole 133 is perpendicular to the direction through which the third assembly hole 132 extends. For example, the direction through which the third assembly hole 132 extends is vertical, and the axis of the assembly hole 133 is horizontal. In some embodiments, the axis of the assembly hole 133 is oriented in the direction of assembly between the watchband 2 and the host 1, i.e., the first direction.

[0147] The third mounting hole 132 includes a first hole 1321 , a second hole 1322 , and a third hole 1323 .

[0148] First hole 1321 is located on the side of base 13 near middle frame 12. After base 13 is connected to middle frame 12, first hole 1321 is opposite and connected to snap-on hole 122. Third hole 1323 is connected to first hole 1321 via second hole 1322. Depending on the shape of base 13, third hole 1323 can be located on the side of base 13 away from middle frame 12, or on the side of base 13. Assembly hole 133 is located on the sidewall of the through hole formed by first hole 1321 and second hole 1322, and may be, but is not limited to, a circular hole.

[0149] In an optional embodiment, a first step surface is formed between the first hole 1321 and the second hole 1322, and the cross-sectional dimension of the first hole 1321 is smaller than the cross-sectional dimension of the second hole 1322. A second step surface is formed between the second hole 1322 and the third hole 1323, and the cross-sectional dimension of the third hole 1323 is larger than the cross-sectional dimension of the second hole 1322.

[0150] The shapes of the first hole 1321, the second hole 1322, and the third hole 1323 include, but are not limited to, waist-shaped holes. The length of the first hole 1321 is shorter than that of the second hole 1322, and the length of the second hole 1322 is shorter than that of the third hole 1323, resulting in the third mounting hole 132 being a stepped hole that tapers along the through-hole direction. It should be noted that the length direction of the first hole 1321, the second hole 1322, and the third hole 1323 corresponds to the length direction of the waist-shaped hole cross section.

[0151] The following combination Figure 7 The structure of the key assembly 32 and the connection relationship between the key assembly 32 and the base 13 are described. Figure 7 The key assembly 32 in FIG. 3 is a structural diagram of an initial state.

[0152] Figure 7 The key assembly 32 includes: a key, an assembly rod 323 and a second spring 324.

[0153] The button includes a thrust portion 321 and a pressing portion 322. The thrust portion 321 and pressing portion 322 are fixedly connected, including but not limited to being integrally formed. The thrust portion 321 is a plate that fits into the first hole 1321 and is movable along the through-hole direction of the first hole 1321. The pressing portion 322 is a structural component that matches the length of the third hole 1323 and is movable along the through-hole direction of the third mounting hole 132. The side of the pressing portion 322 facing away from the thrust portion 321 is a curved surface.

[0154] The thrust portion 321 has an adjustment hole 3211, which is a waist-shaped hole extending along the through direction of the third mounting hole 132. The adjustment hole 3211 is located at one end of the thrust portion 321 close to the pressing portion 322 to reduce the height of the thrust portion 321.

[0155] The assembly rod 323 can be fixedly mounted in the assembly hole 133 along the through-going direction of the third mounting hole 132. The connection between the assembly rod 323 and the assembly hole 133 may include, but is not limited to, an interference fit. In some embodiments, there are two assembly holes 133, located on opposite sides of the third mounting hole 132, with each end of the assembly rod 323 being inserted into one assembly hole 133.

[0156] In some embodiments, one of the assembly holes 133 passes through the middle frame 12 to facilitate the insertion of the assembly rod 323 into the assembly hole 133 and facilitate the installation of the button.

[0157] The assembly rod 323 passes through the adjustment hole 3211, and the thrust portion 321 is movable along the extension direction of the adjustment hole 3211. One end of the second spring 324 abuts against the side of the pressing portion 322 that is connected to the thrust portion 321, while the other end of the second spring 324 abuts against the second stepped surface formed between the second hole 1322 and the third hole 1323.

[0158] When the second spring 324 is at its initial length, the second spring 324 is in a natural state. Under the action of gravity, the assembly rod 323 is against the upper end surface of the adjustment hole 3211, the thrust portion 321 is exposed in the first hole 1321 or retracted in the first hole 1321, and the pressing portion 322 is exposed in the third hole 1323.

[0159] During the process of the second spring 324 being squeezed, that is, the external force pushes the button to move upward in the second direction (from the base 13 toward the middle frame 12, the entire text can refer to this direction), so that the adjustment hole 3211 moves upward relative to the assembly rod 323, and the assembly rod 323 moves from the upper end surface of the adjustment hole 3211 to the lower end surface of the adjustment hole 3211. The thrust portion 321 continues to extend outward from the first hole 1321, and the pressing portion 322 gradually retracts inward into the third hole 1323 until the assembly rod 323 and the lower end surface of the adjustment hole 3211 are against each other.

[0160] It should be noted that the lower end of the adjustment hole 3211 is the end close to the pressing portion 322, and the upper end of the adjustment hole 3211 is the end away from the pressing portion 322. The adjustment hole 3211 and the assembly rod 323 are a limiting structure for the movement of the button.

[0161] The second spring 324 may also be other elastic members, that is, the third elastic member includes but is not limited to the second spring 324 .

[0162] The above content discloses the structure of the watch band 2 and the host 1 of the watch 1000. Figures 8 to 10 The content of this document describes the assembly process of the watch strap 2 and the host 1. Figure 8 The process diagram for inserting the strap 2 into the host 1, Figure 9 for Figure 8 The main cross-sectional view of AA before the middle clamping assembly and the button assembly are assembled. Figure 10 for Figure 8 The main cross-sectional view of AA after the middle clamping assembly and the button assembly are assembled.

[0163] Combine Figure 8 and Figure 9 As shown, when the strap 2 is inserted into the host 1 , one end of the strap 2 having the snap-fit ​​assembly 31 is inserted into the mounting slot 121 of the host 1 along a first direction.

[0164] When the strap 2 is inserted into the installation slot 121, the circumference of the clamping assembly 31 abuts against the installation slot 121, and the clamping member 3121 abuts against the wall of the installation slot 121, so that the clamping member 3121 squeezes the first spring 3123, so that the clamping member 3121 is retracted into the housing 311. In some embodiments, the clamping member 3121 is located at Figure 4 The first mounting hole 31113 is inserted into the housing 311 to reduce the telescopic distance of the clamping member 3121. During the insertion of the strap 2 into the mounting slot 121, the clamping member 3121 is always located in the housing 311 until the strap 2 extends into the preset position in the mounting slot 121.

[0165] like Figure 9 As shown, before the strap 2 is extended to the preset position in the installation slot 121, under the action of gravity, the assembly rod 323 is located at the upper end of the adjustment hole 3211 of the thrust portion 321, and the thrust portion 321 is extended into the snap-fit ​​hole 122. In some embodiments, it is not necessary to extend into the snap-fit ​​hole 122. When the strap 2 is extended to the preset position in the installation slot 121, the snap-fit ​​member 3121 is opposite to the snap-fit ​​hole 122.

[0166] like Figure 10 As shown, the snap-on member 3121 is opposite to the snap-on hole 122, and the squeezed first spring 3123 gradually extends under the reset action, pushing the snap-on member 3121 through the first mounting hole 31113 on the housing 311 into the snap-on hole 122, forming an effective overlap with the snap-on hole 122, completing the detachable fixed connection between the strap 2 and the host 1.

[0167] In some embodiments, when the assembly rod 323 is positioned below the adjustment hole 3211 of the thrust portion 321, the height of the thrust portion 321 is aligned with the end of the engaging hole 122 distal from the base 13. This reduces the travel distance between the engaging member 3121 and the thrust portion 321, thereby reducing the dimension of the connecting assembly 3 along the thickness of the main body 1 and, consequently, the thickness of the watch 1000. The mounting slot 121 is defined on the side of the middle frame 12 and positioned close to the base 13 along the thickness direction. This reduces the depth of the engaging hole 122, further minimizing the travel distance between the engaging member 3121 and the thrust portion 321, and facilitating the thinning and lightweight development of the watch 1000.

[0168] The above content discloses the assembly process of the watch band 2 and the host 1 of the watch 1000. Figure 11 The disassembly process of the watch strap 2 and the host 1 is described. Figure 11 This is a diagram of the state switching process of the first connection component during the strap removal process.

[0169] Combine Figure 11 and Figure 10 As shown, the user applies external force to the pressing portion 322 in Figure a, pushing the pressing portion 322 upward within the third hole 1323. During the movement of the pressing portion 322, the thrust portion 321 drives the clamping member 3121 toward the interior of the housing 311 until the clamping member 3121 disengages from the clamping hole 122 and the assembly rod 323 moves to the lower end surface of the adjustment hole 3211. The thrust portion 321 is flush with the end of the clamping hole 122 away from the base 13, and the second spring 324 is compressed, as shown in Figure b. The user then pulls the watchband 2 outward, removing it from the mounting slot 121. After the watchband 2 is removed, the external force against the pressing portion 322 is removed. Under the reset action of the second spring 324, the button moves downward until the assembly rod 323 contacts the upper end surface of the adjustment hole 3211, exposing the pressing portion 322 to the outside of the main unit 1.

[0170] In some embodiments, when the clamping member 3121 is disengaged from the clamping hole 122, the assembly rod 323 may not have moved to the lower end surface of the adjustment hole 3211, as long as the moving distance of the clamping member 3121 can be completed during the button pressing process.

[0171] Combined with the description of the disassembly and assembly process of the strap 2 and the host 1, it can be seen that the above-mentioned connecting component 3 has a simple structure and is easy to operate and convenient to operate, thereby improving the efficiency and experience of the user in replacing the strap 2.

[0172] The above discloses a structure and assembly relationship of the connection component 3. In some embodiments, the connection component 3 can also be other structures. Figure 12 Referring to the structure of the snap-fit ​​assembly 31 shown in FIG, another structure of the snap-fit ​​assembly 31 of the connecting assembly 3 is described.

[0173] like Figure 12 The illustrated snap-fit ​​assembly 31 includes a housing 311 and a telescopic assembly 312 .

[0174] The housing 311 has a housing cavity inside, and the telescopic assembly 312 is located in the housing cavity. The housing 311 includes a first shell 3111 and a second shell 3112. The connection method of the first shell 3111 and the second shell 3112 can be seen in Figure 4 The connection method of the first shell 3111 and the second shell 3112 is not described here. The shapes and structures of the first shell 3111 and the second shell 3112 can also be seen in Figure 4 Description of the shape and structure of the first shell 3111 and the second shell 3112.

[0175] It should be noted that Figure 12 The top plate 31111 of the first shell 3111 has a second mounting hole 31115 , and the second mounting hole 31115 is a through hole that penetrates the top plate 31111 in the thickness direction.

[0176] Figure 12 The telescopic assembly 312 includes: a clamping member 3121, a first limiting member 3122, a first spring 3123, a driving member 3124 and a third spring 3125.

[0177] The structure, shape and connection relationship of the clamping member 3121 and the first limiting member 3122 can be seen in Figure 4 The structure, shape and connection relationship of the clamping member 3121 and the first limiting member 3122 disclosed in.

[0178] The first spring 3123 abuts between the first limiting member 3122 and the bottom plate of the first housing 3111. The first limiting member 3122 includes a first section and a second section connected in an L shape. The first spring 3123 abuts between the second section and the bottom plate of the first housing 3111.

[0179] The driving member 3124 is connected to the clamping member 3121 through the third spring 3125 , and the driving member 3124 can move along the through direction of the second mounting hole 31115 .

[0180] The driving member 3124 includes an upper section 31241 and a lower section 31242, which are connected to form a stepped structure. In some embodiments, the upper section 31241 and the lower section 31242 are connected to form a T-shape. The upper section 31241 is connected to the second mounting hole 31115, and the connection between the upper section 31241 and the lower section 31242 can abut against the edge of the second mounting hole 31115 to limit the movement of the driving member 3124 and prevent the driving member 3124 from falling out of the second mounting hole 31115.

[0181] The third spring 3125 is positioned between a surface of the lower section 31242 away from the upper section 31241 and a surface of the engaging member 3121 closer to the driving member 3124. In some embodiments, the third spring 3125 includes, but is not limited to, being located in the middle of the length of the engaging member 3121, the two first limiting members 3122 being symmetrically arranged about the third spring 3125, and the first spring 3123 being symmetrically arranged about the third spring 3125. It should be noted that the axis of the third spring 3125 coincides with the centerline of the driving member 3124.

[0182] When the first spring 3123 and the third spring 3125 are both at their initial lengths, the third spring 3125 and the first spring 3123 are both in a compressed state, and the clamping member 3121 is in a balanced state under the action of gravity, the spring force of the third spring 3125 and the spring forces of the two first springs 3123.

[0183] When the first spring 3123 and the third spring 3125 are both at their initial lengths, the upper section of the driving member 3124 extends out of the second mounting hole 31115, i.e., is exposed outside the housing 311, and the clamping member 3121 is located within the first mounting hole 31113, but is not exposed outside the housing 311. In some embodiments, the surface of the clamping member 3121 facing away from the driving member 3124 is flush with the outer surface of the bottom plate of the housing 311. Alternatively, the clamping member 3121 may be retracted into the outer surface of the bottom plate of the housing 311.

[0184] Figure 12 The upper part of the driving member 3124 is acted upon by an external force, pushing the driving member 3124 to move along the second mounting hole 31115 toward the inside of the shell 311. During this process, the driving member 3124 squeezes the third spring 3125, and the third spring 3125 pushes the clamping member 3121 to move along the first mounting hole 31113 toward the outside of the shell 311. During the process of the clamping member 3121 moving toward the outside, the first limiting member 3122 squeezes the first spring 3123, and the first spring 3123 is compressed and deformed under the squeezing of the first limiting member 3122. After the clamping member 3121 moves to the point where the step structure of the first limiting member 3122 and the clamping member 3121 abuts against the edge of the first mounting hole 31113, the clamping member 3121 no longer moves, the driving member 3124 continues to move, and the third spring 3125 is squeezed and deformed.

[0185] In some embodiments, the first limiting member 3122 may not limit the clamping member 3121 and may only be used to connect the first spring 3123 and the third spring 3125. The moving distance of the clamping member 3121 can be set by the spring force of the first spring 3123 and the third spring 3125.

[0186] In some embodiments, the driver 3124 and the connector 3121 can be constructed from different materials as needed. For example, the driver 3124 can be constructed from a wear-resistant material, including but not limited to polyoxymethylene resin, while the connector 3121 can be constructed from, but not limited to, high-strength metal. In some embodiments, the side of the upper section 31241 of the driver 3124 facing away from the lower section 31242 is the upper end surface, and the distance from the upper end surface to the lower section 31242 gradually increases from the edge of the upper end surface to the center of the upper end surface.

[0187] The end surface of the upper section 31241 of the driving member 3124 is an arc surface, and the distance from the edge of the arc surface to the lower section 31242 is smaller than the distance from the top surface of the arc surface to the lower section 31242 .

[0188] It should be noted that the third spring 3125 may also be other elastic members, that is, the second elastic member includes but is not limited to the third spring 3125 .

[0189] The above content is an explanation of another structure of the clamping assembly 31 disclosed in this application. Figure 4 and Figure 12 The two different structures of the clamping assembly 31 in FIG. 3 have the following advantages.

[0190] Figure 4 The clamping assembly 31 has a simple structure, a small number of parts, and a low production cost; and the clamping member 3121 and the first limiting member 3122 are integrally formed, which can reduce the assembly process and improve assembly efficiency.

[0191] Figure 12 The advantage of the clamping assembly 31 is that the driving member 3124 and the clamping member 3121 are two separate components, and both can extend outward from the housing 311; Figure 13 As shown, the clamping member 3121 and the driving member 3124 are connected by the third spring 3125, and the upper end surface of the driving member 3124 is an arc surface. When the strap 2 is inserted into the host 1, the edge of the arc surface of the driving member 3124 first abuts against the installation groove 121 until the top of the arc surface abuts against the installation groove 121. During this process, the clamping member 3121 gradually moves to the outer edge of the first mounting hole 31113. Therefore, Figure 12 The clamping assembly 31 can reduce the clamping part 3121 in Figure 13 Some wear within the distance a is reduced, so the clamping part 3121 does not need to be chamfered, ensuring the overlapping area between the clamping part 3121 and the clamping hole 122; the first spring 3123 and the third spring 3125 are staggered and parallel, and overlap in the height direction, which can reduce the height distance of the clamping assembly 31.

[0192] It should be noted that the structure of the snap-fit ​​assembly 31 can be set according to different needs. As long as the structure has a snap-fit ​​component 3121 that can be extended and retracted along the thickness direction of the strap, it is within the protection range.

[0193] The following is based on Figure 14 and Figure 15 Another structure of the key assembly 32 and its connection with the base 13 are described. Figure 14 A partial cross-sectional view of a base on which a key assembly of another structure is installed. Figure 15 Schematic diagram of another structure of the button assembly 32.

[0194] like Figure 14 and Figure 15As shown, the button assembly 32 includes: a button, a second spring 324 , a second limiting member 325 and a connecting member 326 .

[0195] The structure and connection relationship of the buttons can be found in Figure 7 The structure and connection relationship of the middle button, the connection relationship and connection position of the second spring 324 and the button are shown in FIG. Figure 7 The connection relationship and connection position between the second spring 324 and the button are not described here.

[0196] The connecting piece 326 is fixedly connected to the end of the pressing portion 322 and is located on the same side of the pressing portion 322 as the thrust portion 321 . The connecting piece 326 and the pressing portion 322 are, but not limited to, integrally formed.

[0197] The connecting piece 326 is an L-shaped structure, and the connecting piece 326 is bent in a direction away from the thrust portion 321 . A U-shaped groove structure is formed between the connecting piece 326 and the pressing portion 322 , and the opening of the U-shaped groove structure faces the outside of the key.

[0198] Figure 14 The shape, size and connection method of the middle base 13 and the middle frame 12 can be found in Figure 5 and Figure 6 The shape and size of the middle base 13 and the connection method between the base 13 and the middle frame 12. Figure 14 The base 13 includes a third mounting hole 132 , and the third mounting hole 132 includes a first hole 1321 , a second hole 1322 and a third hole 1323 .

[0199] Figure 14 The third mounting hole 132 in Figure 6 The difference between third mounting holes 132 is that the cross-sectional dimensions of first hole 1321 are smaller than those of third hole 1323, and the cross-sectional dimensions of third hole 1323 are smaller than those of second hole 1322. This results in a first stepped surface being formed between first hole 1321 and second hole 1322, and a second stepped surface being formed between second hole 1322 and third hole 1323, with the first and second stepped surfaces facing each other. It is understood that second hole 1322 may be a receiving groove on the sidewall of third mounting hole 132.

[0200] Combine Figure 14 The assembly relationship between the middle button assembly 32 and the base 13 shows that the second spring 324 is located between the first step surface and the pressing portion 322 , and two ends of the second spring 324 respectively abut against the first step surface and the pressing portion 322 .

[0201] The second stopper 325 is installed in the second hole 1322, i.e., in the receiving groove, and is fixed to the second step surface. The second stopper 325 extends into the U-shaped groove structure formed between the bridge 326 and the pressing portion 322, with the U-shaped groove structure facing the side wall of the third mounting hole 132. As the key moves along the third mounting hole 132, the second stopper 325 abuts against the bridge 326, limiting the key's movement to the lower limit point; the pressing portion 322 abuts against the second stopper 325, limiting the key's movement to the upper limit point.

[0202] That is, the connecting member 326 and the second limiting member 325 form a limiting structure for the movement of the key.

[0203] When the second spring 324 is at its initial length, the second limit piece 325 abuts against the connecting piece 326, and the button is at the lower dead point; the pressing part 322 is subjected to force, and during the process of pushing upward along the second direction, the second spring 324 is compressed, and the pressing part 322 gradually approaches the second limit piece 325, and when the pressing part 322 abuts against the second limit piece 325, the button moves to the upper dead point.

[0204] In some embodiments, the second stopper 325 is a U-shaped elastic clip. The U-shaped elastic clip is engaged within the second hole 1322 by virtue of its restoring force, with its two side edges respectively abutting against the first step surface and the second step surface. The use of a U-shaped elastic clip allows for the position-limiting installation of the second stopper 325 without requiring additional connectors, simplifying the connection and facilitating assembly.

[0205] The first end of the U-shaped elastic clip is fixedly connected to the first stepped surface, including but not limited to welding. The second end of the U-shaped elastic clip abuts against the second stepped surface and extends into the U-shaped groove structure formed between the bridge 326 and the pressing portion 322. As the key moves along the third mounting hole 132, the second end of the U-shaped elastic clip can abut against the pressing portion 322 and the bridge 326 to limit its position.

[0206] In some embodiments, there are two bridging members 326, located at both ends of the pressing portion 322. A second stopper 325 is disposed on the first stepped surface and faces one of the two bridging members 326. For ease of description, the two bridging members 326 are defined as a first bridging member and a second bridging member. The first bridging member faces the second stopper 325, and when the first bridging member and the second stopper 325 abut against each other, the second bridging member abuts against the second stepped surface.

[0207] Providing a second limiting member 325 can simplify the structure, reduce the number of components, and lower costs.

[0208] By comparison Figure 7 and Figure 15The two different structures of the key assembly 32 in FIG. 3 show that both have the following advantages.

[0209] Figure 7 The key assembly 32 in the embodiment uses an assembly rod 323 and an adjustment hole 3211 to limit the movement position of the key, which has a convenient structure and is easy to process. The matching relationship between the assembly rod 323 and the adjustment hole 3211 can guide the movement of the key. Figure 7 The size of the third mounting hole 132 increases gradually along the through direction, so the processing of the third mounting hole 132 can be simplified; the anti-key-out method of the assembly rod 323 and the assembly hole 133 does not occupy the space of the third mounting hole 132, can ensure that the key has sufficient space for movement, and the size requirement for the third mounting hole 132 is relatively low.

[0210] Figure 15 The key assembly 32 adopts the cooperation of the bridging member 326 and the second limiting member 325 to limit the moving position of the key, which can facilitate the assembly of the key assembly 32; the bridging member 326 and the key are integrally formed, which simplifies the structure and improves the assembly efficiency; the second limiting member 325 cooperates with the U-shaped groove structure, and the cooperation accuracy requirement is small.

[0211] The above content discloses another structure of the clamping assembly 31 and the key assembly 32. Figures 16 to 18 The assembly process of the connection component 3 for the watch band 2 of the watch 1000 and the host 1 is described. Figure 16 The process diagram for inserting the strap 2 into the host 1, Figure 17 for Figure 16 The main cross-sectional view of the BB before assembly of the second structure of the middle clamping assembly and the second structure of the button assembly, Figure 18 for Figure 16 The main cross-sectional view of the BB after assembly of the second structure of the middle snap-in assembly and the second structure of the button assembly.

[0212] See also Figure 16 , insert one end of the strap 2 with the snap-connecting component 31 into the mounting slot 121 of the host 1. Under the circumferential limiting action of the mounting slot 121, the driving member 3124 and the snap-connecting member 3121 are pressurized, and the third spring 3125 is compressed until the driving member 3124 and the snap-connecting member 3121 are retracted into the housing 311, until the strap 2 extends into the preset position in the mounting slot 121.

[0213] Combine Figure 14 、 Figure 16 and Figure 17 Before the button assembly 32 in the watch strap 2 is inserted into the preset position in the installation slot 121, the button assembly 32 is subjected to the action of gravity, and the connecting member 326 and the second limiting member 325 are against each other.

[0214] like Figure 18 As shown, the strap 2 extends into the preset position in the installation slot 121, the snap-in component 3121 is opposite to the snap-in hole 122, the squeezed third spring 3125 is extended, and under the spring force of the third spring 3125, the snap-in component 3121 passes through the housing 311 and extends into the snap-in hole 122, achieving effective overlap between the snap-in component 3121 and the snap-in hole 122, and completing the detachable fixed connection between the strap 2 and the host 1.

[0215] In some embodiments, when the second stopper 325 abuts the pressing portion 322, the height of the thrust portion 321 is flush with the end of the engaging hole 122 away from the base 13. This reduces the travel distance of the engaging member 3121 and the thrust portion 321, thereby reducing the dimension of the connecting assembly 3 along the thickness direction of the main body 1, and thus reducing the thickness of the watch 1000. The mounting slot 121 is defined on the side of the middle frame 12 and arranged close to the base 13 along the thickness direction to reduce the depth of the engaging hole 122, further reducing the travel distance of the engaging member 3121 and the thrust portion 321, and facilitating the thinning and lightweight development of the watch 1000.

[0216] The above content describes the assembly process of the watch band 2 and the host 1 of the watch 1000 using another structure of the connecting component 3. Figure 19 The disassembly process of the watch strap 2 and the host 1 is described. Figure 19 This is a state switching process diagram of the second structure of the connecting component during the strap removal process.

[0217] Combine Figure 19 and Figure 18 As shown, the user applies an external force toward the main unit 1 to the pressing portion 322 in Figure a, pushing the pressing portion 322 upward within the third hole 1323. During the movement of the pressing portion 322, the thrust portion 321 drives the clamping member 3121 toward the interior of the housing 311. The second limiting member 325 abuts against the connecting member 326 and gradually approaches the pressing portion 322 until the clamping member 3121 is disengaged from the clamping hole 122. The second limiting member 325 abuts against or approaches the pressing portion 322, as shown in Figure b. When the clamping member 3121 is disengaged from the clamping hole 122, the thrust portion 321 is flush with the end of the clamping hole 122 away from the base 13, and the second spring 324 is compressed. The user pulls the watchband 2 outward to remove it from the mounting slot 121.

[0218] After the strap 2 is pulled out, the external force against the pressing portion 322 is canceled. Under the action of the second spring 324 , the button moves downward, the pressing portion 322 is exposed to the host 1 , and the second limiter 325 abuts against the pressing portion 322 .

[0219] Combined with the description of the disassembly and assembly process of the strap 2 and the host 1, it can be seen that the above-mentioned connecting component 3 has a simple structure and is easy to operate and convenient to operate, thereby improving the efficiency and experience of the user in replacing the strap 2.

[0220] The above content discloses different structures of the connecting component 3. In some embodiments, different connection methods of the connecting component 3 and the strap 2 are also disclosed. Figure 20 and Figure 21 As shown, Figure 20 This is an assembly diagram of the second connection method between the snap-fit ​​assembly 31 and the strap 2. Figure 21 This is an assembly diagram of the third connection method between the snap-fit ​​assembly 31 and the strap 2.

[0221] like Figure 20 As shown, the snap-on assembly 31 includes a housing 311 and a connecting post 313. The watchband 2 includes a connecting hole 22, which is located at the end of the watchband 2. The number, shape, and spacing of the connecting holes 22 and connecting posts 313 can be set according to different needs. Optionally, the connecting holes 22 are circular holes, and the connecting posts 313 are cylindrical.

[0222] The housing 311 includes a first housing 3111 and a second housing 3112. The structure of the housing 311 can be seen in Figure 4 The description of the middle shell 311 is omitted here.

[0223] The connecting post 313 is fixed between the bottom plate and the back plate of the housing 311 , and the connecting hole 22 can be sleeved on the connecting post 313 to achieve the connection between the watchband 2 and the housing 311 .

[0224] In some embodiments, the strap 2 may be a woven strap, and a connection hole 22 may be formed by weaving an opening at the end of the woven strap; or a connection hole 22 may be formed by opening a hole at the end of the strap 2 by pulse hot pressing, laser punching, or mechanical punching.

[0225] like Figure 21 As shown, the snap-on assembly 31 includes a housing 311 and a lug 314 .

[0226] The housing 311 includes a first housing 3111 and a second housing 3112. The structure of the housing 311 can be seen in Figure 4 The description of the middle shell 311 is omitted here.

[0227] There are two lugs 314, located on either side of the second housing 3112, and facing each other. The strap 2 has a lever (not shown) for engaging the lugs 314. The lever is of a standard size, allowing the clip assembly 31 to adapt to any existing strap size, thus achieving standardization.

[0228] Combine Figure 3 、 Figure 20 and Figure 21 As can be seen from the connection methods of the illustrated snap-on assembly 31 and the strap 2 , the three different connection methods each have the following advantages.

[0229] in, Figure 3 The snap-fit ​​assembly 31 shown in the figure is connected to the strap 2 by a matching snap-fit ​​connection method, which does not require any connecting parts, so the structure is simple and the cost is low; the processing accuracy requirements are low, and it is easy to disassemble and assemble.

[0230] Figure 20 The connection method between the snap-on assembly 31 and the strap 2 shown in the figure is achieved through the connection between the connecting column 313 and the connecting hole 22. This connection method is reliable and can be applied to the connection of straps of different materials and different sizes.

[0231] Figure 21 The connection method between the snap-on assembly 31 and the watch strap 2 through the watch lugs and the lever is applicable to existing watch straps, which increases the scope of replacement and reduces the cost of watch strap replacement.

[0232] It should be noted that the above content discloses three different connection methods between the strap 2 and the snap-on assembly 31, and discloses two different structures of the snap-on assembly 31. In addition, two different structures of the button assembly 32 are also disclosed. In other embodiments, the above contents can be combined according to different needs, and they are all within the scope of protection and will not be repeated here.

[0233] In some embodiments, there are usually two watch straps 2, which are respectively connected to two sides of the host 1, and at least one of the two watch straps 2 adopts the connection method disclosed above.

[0234] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the watch. In other embodiments of the present application, the watch may include more or fewer components than shown, or combine some components, or split some components, or arrange the components differently.

[0235] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
