Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of spring ear components, and in particular to a spring ear component, a watch strap, and a wrist-worn wearable device. Background Technology
[0002] As an essential component of wrist-worn wearable devices, watch straps are needed to meet various occasions or for users to replace due to damage. Currently, watch straps are typically connected to the device body via spring bars. Spring bars have a certain strength and are assembled and disassembled with the watch head via telescopic pins. For example, when a user needs to replace the watch strap, they first remove the spring bar from the device body, then replace it with a new strap, and then reconnect the spring bar to the device body. Because the connection between the spring bar and the device body is quite tight, it often requires professional tools for disassembly or a visit to a watch repair shop to replace the strap. This makes replacing watch straps quite cumbersome and affects the user experience.
[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

The linkage member has a first clearance groove and a reinforcing portion located outside the first clearance groove. The drive assembly extends at least partially into the first clearance groove and is connected to the linkage member.
[0007] As described above, in a spring ear assembly, the drive assembly includes an operating member that is vertically and elliptically disposed on the spring ear housing, and a guide mechanism disposed between the operating member and the linkage member; the operating member moves vertically and elliptically relative to the spring ear housing, and the linkage member slides laterally within the spring ear housing through the guide mechanism, and the spring ear rod extends and retracts laterally within and outside the spring ear housing through the linkage member.
[0008] As described above, in a spring ear assembly, the guiding mechanism includes a first guiding portion disposed on the operating member and a second guiding portion disposed on the linkage member. The second guiding portion is located on one side of the first clearance groove and connected to the reinforcing portion. The operating member and the linkage member are slidably connected through the first guiding portion and the second guiding portion. At least one of the relative sliding surfaces between the first guiding portion and the second guiding portion is an inclined driving surface.

[0012] In the spring ear assembly described above, the linkage further includes a connecting portion located on one side of the reinforcing portion and the first clearance groove, and the spring ear rod is located on the side of the connecting portion away from the reinforcing portion.
[0013] As described above, in a spring ear assembly, the drive assembly further includes a reset member disposed on one side of the linkage member, which causes the linkage member to extend outward toward the outside of the spring ear housing and drives the spring ear rod to extend outward to the outside of the spring ear housing; the end of the linkage member away from the spring ear rod is also provided with a mounting part, which is used to mount the reset member.
[0014] This utility model also provides a watch strap, including a body and a spring bar assembly as described above, wherein the spring bar assembly is connected to the body.

[0036] Example 1:
[0037] like Figure 1As shown in Figure 13, this utility model provides a wrist-worn wearable device, including a watch head (not shown), a watch strap, and a spring bar assembly 100. The watch strap includes a body 200, which is installed in the watch head via the spring bar assembly 100. The wrist-worn wearable device includes, but is not limited to, mechanical watches, quartz watches, electronic watches, children's watches, smartwatches, smart bracelets, and other wearable devices. The watch strap includes, but is not limited to, watch straps made of various materials such as leather, cloth, metal, rubber, and ceramic. The spring bar assembly 100 can be used with the above-mentioned different wearable devices and watch straps, and this embodiment does not make specific limitations. The spring bar assembly 100 allows the watch strap to be detachably installed in the watch head, which facilitates the user to replace the watch strap and maintain the watch head.
[0038] Specifically, such as Figure 1 As shown in Figure 5, the spring ear assembly 100 includes a spring ear housing 110, at least one spring ear rod 130 slidably disposed in the spring ear housing 110, a linkage member 140 connected to the spring ear rod 130, and a drive assembly connected to the linkage member 140. The drive assembly drives the linkage member 140 to slide within the spring ear housing 110, thereby causing the spring ear rod 130 to extend and retract within and outside the spring ear housing 110. In this embodiment, spring ear rods 130 are provided on both sides of the spring ear housing 110 for cooperating with the meter head, thereby achieving locking between the spring ear assembly 100 and the meter head; at least one of the spring ear rods 130... The spring bar 130 is slidably disposed in the spring bar housing 110, that is, one spring bar 130 can be fixedly disposed in the spring bar housing 110, and the other spring bar 130 is slidably connected in the spring bar housing 110. The slidably connected spring bar 130 can extend and retract relative to the spring bar housing 110 through the linkage 140. In practical applications, when the slidably connected spring bar 130 extends outside the spring bar housing 110, it can be inserted into the locking hole of the watch head. At this time, the spring bar assembly 100 is locked relative to the watch head, and the body 200 of the watch strap can be fixedly installed in the watch head. Figure 5 As shown, when the driving component drives the linkage 140 to retract laterally toward the spring bar housing 110, and drives the slidingly connected spring bar rod 130 to retract laterally into the spring bar housing 110, the spring bar assembly 100 is switched to an unlocked state relative to the watch head, at which point the watch strap can be detached; thus realizing the assembly and disassembly of the spring bar assembly 100 and the watch head, allowing the user to assemble and disassemble the spring bar assembly 100 with one click, greatly reducing the difficulty of assembling and disassembling the spring bar assembly 100, and making it convenient for users to disassemble and disassemble the spring bar assembly 100 themselves to replace the watch strap or repair the watch head; in addition, as Figure 2As shown in Figure 5, the linkage 140 is provided with a first clearance groove 141 and a reinforcing part 142 located outside the first clearance groove 141. The top wall of the reinforcing part 142 is located between the bottom of the first clearance groove 141 and the top of the linkage 140. The driving assembly extends at least partially into the first clearance groove 141 and is connected to the linkage 140. In this embodiment, as shown... Figure 3 As shown, the top of the linkage 140 is recessed downward to form the first clearance groove 141, and the reinforcing part 142 is formed on the front and / or rear side of the first clearance groove 141, which helps to enhance the structural strength of the linkage 140, improve the motion stability of the linkage 140, and extend the service life of the linkage 140.
[0039] Specifically, such as Figure 2As shown in Figure 5, the drive assembly includes an operating member 120 that is vertically and flexibly disposed on the spring ear housing 110, and a guide mechanism 150 disposed between the operating member 120 and the linkage member 140. The operating member 120 extends at least partially into a first clearance groove 141, which provides sufficient space for the longitudinal displacement of the operating member 120. The operating member 120 is slidably connected to the linkage member 140 via the guide mechanism 150, and the guide mechanism 150 facilitates the longitudinal displacement of the operating member 120. The movement is linked to the lateral displacement of the linkage 140; the operating member 120 is subjected to force and moves up and down relative to the spring ear housing 110, and the linkage 140 slides laterally within the spring ear housing 110 through the guide mechanism 150. The linkage 140 drives the spring ear rod 130 to extend and retract laterally inside and outside the spring ear housing 110, thereby realizing the locking and unlocking states of the spring ear assembly 100; specifically, when the spring ear assembly 100 is in the locked state, the slidably connected spring ear rod 130 extends into the spring ear. The exterior of the housing 110; when the operating member 120 is pressed and retracts longitudinally toward the spring ear housing 110, the operating member 120 drives the linkage member 140 to retract laterally toward the spring ear housing 110 via the guide mechanism 150, and drives the slidingly connected spring ear rod 130 to retract laterally into the interior of the spring ear housing 110, so that the spring ear assembly 100 is converted to the unlocked state; optionally, the operating member 120 can be set as a button; by setting the guide mechanism 150 between the operating member 120 and the linkage member 140 50, enabling one-click assembly and disassembly of the spring bar assembly 100, greatly reducing the difficulty of assembly and disassembly of the spring bar assembly 100, and making it convenient for users to disassemble and assemble the spring bar assembly 100 themselves to replace the watch strap or repair the watch head; in addition, during the relative sliding process of the operating member 120 and the linkage member 140, the reinforcing part 142 is located on both sides of the operating member 120, so that the first clearance groove 141 forms a sliding guide groove for the operating member 120 to slide, which helps to improve the movement stability of the operating member 120, thereby improving the stability of the spring bar assembly 100.
[0040] Furthermore, such as Figure 2As shown in Figure 5, the guiding mechanism 150 includes a first guiding portion 151 disposed on the operating member 120 and a second guiding portion 152 disposed on the linkage member 140. The second guiding portion 152 is located on one side of the first clearance groove 141 and connected to the reinforcing portion 142 to enhance the structural strength of the linkage member 140. The operating member 120 and the linkage member 140 are slidably connected through the first guiding portion 151 and the second guiding portion 152. At least one of the relative sliding surfaces between the first guiding portion 151 and the second guiding portion 152 is an inclined driving surface 153, which exerts a lateral force on the linkage member 140. In this embodiment, the relative sliding surfaces of the first guiding portion 151 and the second guiding portion 152 are a first sliding surface 1511 and a second sliding surface 1512, respectively. At least one of the first sliding surface 1511 and the second sliding surface 1512 is inclined, and this inclined sliding surface is defined as the driving surface 153. Figure 6 As shown, the first sliding surface 1511 is located to the upper left of the second sliding surface 1512. The first sliding surface 1511 is set as an inclined surface sloping downward to the right, thus the first sliding surface 1511 serves as the driving surface 153. The linkage action of the guide mechanism 150 is as follows: when the user presses the operating member 120 downward, relative sliding occurs between the first sliding surface 1511 and the second sliding surface 1512. At this time, the first sliding surface 1511 generates a lateral component force on the linkage member 140, causing it to retract towards the inward movement of the spring ear shell 110 (e.g., Figure 5 The first sliding surface 1511 shown exerts a rightward pushing force on the linkage 140. As the operating member 120 moves downward, the linkage 140 drives the slidingly connected spring bar 130 to move laterally and retract into the spring bar housing 110. When the user releases the operating member 120, the linkage 140 is forced to extend outward from the spring bar housing 110, thereby driving the slidingly connected spring bar 130 to extend outward from the spring bar housing 110. At the same time, the second sliding surface 1512 generates a longitudinal force on the operating member 120 to extend outward from the spring bar housing 110 (e.g., ...). Figure 4 The second sliding surface 1512 shown has an upward pushing force on the operating member 120, causing the operating member 120 to move upward, reset, and extend outside the spring ear housing 110. In this invention, the first sliding surface 1511 can serve as the driving surface 153, or the second sliding surface 1512 can serve as the driving surface 153, or both the first sliding surface 1511 and the second sliding surface 1512 can be configured as mutually cooperating driving surfaces 153; specifically, the driving surface 153 can be configured as an inclined plane, such as... Figure 6 and Figure 8 The first sliding surface 1511 shown is an inclined plane; the driving surface 153 can also be set as an arc surface, such as... Figure 7 and Figure 9The first sliding surface 1511 shown is an arc surface; in this embodiment, the other sliding surface that cooperates with the driving surface 153 is not limited. The sliding surface can also be set as an inclined plane or an arc surface, etc., which can cooperate with the driving surface 153 to slide relative to each other; in addition, by adjusting the orientation and position of the first sliding surface 1511 and the second sliding surface 1512, the linkage 140 can be driven to retract toward the ear shell 110 through the guide mechanism 150 when the operating member 120 moves upward, and the linkage 140 can be driven to extend toward the outside of the ear shell 110 through the guide mechanism 150 when the operating member 120 moves downward to reset. This utility model does not make specific limitations. By setting the guide mechanism 150 between the operating component 120 and the linkage component 140, the spring bar assembly 100 can be disassembled and assembled with one click, greatly reducing the difficulty of disassembling and assembling the spring bar, and making it convenient for users to disassemble and assemble the spring bar assembly 100 themselves to replace the watch strap or repair the watch head; in addition, by directly setting the first guide part 151 in the operating component 120 and directly setting the second guide part 152 in the linkage component 140, the number of parts of the spring bar assembly 100 can be reduced, making the overall structure of the spring bar assembly 100 more compact, which is conducive to improving the assembly efficiency of the spring bar assembly 100 and reducing the size of the spring bar assembly 100.
[0041] In other alternative embodiments, such as Figure 2 As shown in Figure 5, the operating member 120 is provided with a second clearance groove 121 facing the linkage member 140. The bottom of the operating member 120 is recessed upward to form the second clearance groove 121, which provides sufficient movement space for the linkage member 140. The first guide portion 151 is located on one side of the second clearance groove 121. The bottom of the first clearance groove 141 and / or the top of the second clearance groove 121 are provided with a first limiting portion 170, which restricts the lateral movement of the linkage member 140. Figure 4 and Figure 5 As shown, in this embodiment, when the operating member 120 moves down, the linkage member 140 is guided by the first guide part 151 to retract laterally into the spring ear housing 110. The operating member 120 moves down until it abuts against the bottom of the first clearance groove 141 and stops, or the operating member 120 moves down until the top of the second clearance groove 121 abuts against the top of the linkage member 140 and stops, or the operating member 120 moves down until it abuts against the bottom of the first clearance groove 141 and the top of the second clearance groove 121 abuts against the top of the linkage member 140 and stops. At this time, the slidingly connected spring ear rod 130 retracts into the spring ear housing 110 to achieve the unlocked state of the spring ear assembly 100, which is beneficial to ensure the normal disassembly of the spring ear assembly 100 and improve the disassembly and assembly efficiency of the spring ear assembly 100.
[0042] In some alternative embodiments, the spring ear housing 110 includes a first sleeve 111 and a second sleeve 112 disposed on one side of the first sleeve 111. The first sleeve 111 has a first receiving cavity 1111 for sliding of the operating member 120, and the second sleeve 112 has a second receiving cavity 1121 for sliding of the linkage member 140 and the spring ear rod 130. The first receiving cavity 1111 and the second receiving cavity 1121 are connected. Figure 3 and Figure 4 As shown, the first sleeve 111 is located above the second sleeve 112. The first receiving cavity 1111 extends longitudinally through the first sleeve 111 to allow the operating member 120 to be slidably installed, and to ensure that the operating member 120 can extend through the top of the first sleeve 111 to the outside of the spring ear housing 110 for user operation. The second receiving cavity 1121 extends transversely through the second sleeve 112 to allow the spring ear rod 130 to be slidably installed, and to ensure that the slidably connected spring ear rod 130 can extend through the end of the second sleeve 112 to the outside of the spring ear housing 110 and connect to the meter head. The first receiving cavity 1111 and the second receiving cavity 1121 are connected to allow the operating member 120 and the linkage member 140 to be slidably connected through the guide mechanism 150. In addition, as Figure 10 As shown, the bottom of the first sleeve 111 is provided with an extension 1112 extending toward the second receiving cavity 1121. The extension 1112 abuts against the reinforcing part 142, and a sliding guide groove for the linkage 140 to slide is formed between the extension 1112 and the bottom of the second receiving cavity 1121, so as to improve the sliding stability of the linkage 140 and further improve the reliability of the spring ear assembly 100.
[0043] In some alternative embodiments, to further improve the reliability of the spring ear assembly 100, a second limiting part 122 is provided on the outer side of the operating member 120 to restrict the lateral movement of the linkage member 140; in this embodiment, such as Figure 4 As shown, the bottom outer side of the operating member 120 is provided with a second limiting part 122. The second limiting part 122 is opposite to the bottom of the first sleeve 111. By the second limiting part 122 abutting against the bottom of the first sleeve 111, the upward movement distance of the operating member 120 during reset is limited, so as to prevent the operating member 120 from disengaging from the first sleeve 111 when it moves upward to reset, thus ensuring the normal use of the spring ear assembly 100.
[0044] like Figure 4As shown, the linkage 140 also has a connecting portion 143 located on one side of the reinforcing portion 142 and the first clearance groove 141. The connecting portion 143 is used to connect the spring bar 130. The spring bar 130 is located on the side of the connecting portion 143 away from the reinforcing portion 142, and the spring bar 130 is connected to the inner side of the connecting portion 143. In actual production, the connection strength between the linkage 140 and the spring bar 130 can be increased by adjusting the connection length between the connecting portion 143 and the spring bar 130 (i.e., the insertion length of the spring bar 130 in the connecting portion 143), thereby improving the structural stability of the spring bar assembly 100. It should be noted that the connection length of the spring bar 130 in the connecting portion 143 does not affect the length of the spring bar 130 exposed outside the linkage 140. The length of the spring bar 130 exposed outside the linkage 140 is a fixed value and can be set according to the depth of the lock hole in the meter head.
[0045] In some alternative embodiments, the linkage 140 is integrally formed from metal or plastic materials to reduce the manufacturing difficulty of the linkage 140.
[0046] In some alternative embodiments, the linkage 140 and the spring bar 130 are connected separately. For example, the spring bar 130 is directly fixed to the linkage 140 by means of snap-fit, plug-in or threaded connection, so as to reduce the assembly difficulty of the linkage 140 and the spring bar 130. In some alternative embodiments, the linkage 140 and the spring bar 130 are integrally formed, so as to reduce the assembly difficulty of the spring bar assembly 100 and further improve the assembly efficiency of the linkage 140 and the spring bar 130.
[0047] Optionally, the spring bar 130 is typically made of metal. During production, the spring bar 130 can be fixed in an injection mold corresponding to the linkage 140, and the linkage 140 can be formed by injection molding directly onto the spring bar 130 using this injection mold. This improves the structural strength between the linkage 140 and the spring bar 130, thereby enhancing the connection stability between the linkage 140 and the spring bar 130. Furthermore, the linkage 140 made of plastic is lighter, reducing the driving force required for the inward sliding of the linkage 140, thus reducing the driving load of the operating element 120 on the linkage 140. This makes it easier for the user to press the operating element 120 to disassemble the spring bar assembly 100, optimizing the user experience. Additionally, using plastic to manufacture the linkage 140 helps reduce its production cost. Figure 11 and Figure 12 As shown, if the surface of the part of the rod 130 connected to the linkage 140 has the following characteristics... Figure 11 The grooves shown and / or as Figure 12As shown, during the injection molding process, the inner side of the linkage 140 directly forms a mating shape that matches the groove or protrusion in the spring bar 130, which helps to further improve the connection stability and structural strength between the spring bar 130 and the linkage 140, effectively preventing the spring bar 130 from detaching from the linkage 140 and ensuring the normal use of the spring bar assembly 100.
[0048] like Figure 4 As shown, the drive assembly also includes a reset member 160 disposed on one side of the linkage member 140. The reset member 160 causes the linkage member 140 to extend outward toward the outside of the spring ear housing 110, and drives the spring ear rod 130 to extend outward to the outside of the spring ear housing 110. In practical applications, when the spring ear assembly 100 is in the unlocked state, the reset member 160 is compressed, such as... Figure 4 As shown, when the pressure applied to the operating member 120 is released, the reset member 160 pushes the linkage member 140 to extend laterally outward toward the outside of the spring ear housing 110, thereby causing the slidably connected spring ear rod 130 to extend outward to the outside of the spring ear housing 110. Simultaneously, the linkage member 140, through the guide mechanism 150, drives the operating member 120 to move upward relative to the outside of the spring ear housing 110 and extend outward, so that the spring ear assembly 100 automatically changes from the unlocked state to the locked state, and the operating member 120 automatically resets, further reducing the user's operational burden. The difficulty is reduced, which improves the flexibility and assembly / disassembly efficiency of the spring ear assembly 100; the end of the linkage 140 away from the spring ear rod 130 is also provided with an installation part 144, which is used to install the reset part 160. Optionally, the installation part 144 extends laterally away from the spring ear rod 130, and the reset part 160 is sleeved on the outside of the installation part 144. The structure is simple and easy to assemble and disassemble the reset part 160. In this embodiment, the longitudinal section of the installation part 144 includes, but is not limited to, circular, rectangular and other shapes, and the reset part 160 includes, but is not limited to, elastic elements such as springs. This utility model is not specifically limited.
[0049] Example 2:
[0050] The difference between this embodiment 2 and embodiment 1 is that, Figure 2 As shown in Figure 5, the spring ear housing 110 has spring ear rods 130 slidably disposed on both sides. A linkage 140 is provided between each of the two spring ear rods 130 and the operating member 120, and a guide mechanism 150 is provided between the operating member 120 and the two linkages 140. A reset member 160 is disposed between the two linkages 140. In this embodiment, the two slidably disposed spring ear rods 130 form bidirectional telescopic pins within the spring ear housing 110, such as... Figure 4As shown, when the operating member 120 moves downward, the first guide portions 151 on both sides drive the two linkage members 140 to retract and move towards each other, thereby causing the two spring ear rods 130 to retract and move towards each other and into the spring ear housing 110, thus realizing the unlocked state of the spring ear assembly 100; as Figure 4 As shown, when the operating member 120 is released, the two linkage members 140 are pushed by the reset member 160 and move away from each other, so as to drive the two spring ear rods 130 to move away from each other and extend to the outside of the spring ear housing 110, so as to realize the locked state of the spring ear assembly 100. At the same time, the second guide part 152 of the two linkage members 140 drives the operating member 120 to move upward and reset. It should be noted that the specific movement law of any of the spring ear rods 130 is as described in Embodiment 1, and will not be repeated in this embodiment.
[0051] In some alternative embodiments, the operating member 120 may be a component with symmetrical legs, such as a U-shaped member, and this utility model does not impose any specific limitations.
[0052] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
