Flexible pin assembly, watch strap, watch body and wearable devices

[0001] This application claims priority to Chinese Patent Application No. 202411958314.2, filed on December 27, 2024, with the invention entitled "Elastic Thruster Assembly, Watch Strap, Watch Body and Wearable Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wearable device technology, and in particular to an elastic pin assembly, a watch strap, a watch body, and a wearable device. Background Technology

[0003] In today's society, people have increasingly higher demands for the functions of wearable devices. Users hope that more functions can be integrated into wearable devices. The more functional components are integrated into the watch body, the larger and heavier the watch body becomes, resulting in a poor user experience. Summary of the Invention

[0004] This application provides a flexible pin assembly, a watch strap, a watch body, and a wearable device.

[0005] In a first aspect, embodiments of this application provide an elastic ejector pin assembly. The elastic ejector pin assembly includes an ejector pin, an elastic element, a wire, and a housing. A first end of the ejector pin protrudes outside the housing, a second end of the ejector pin is located inside the housing, the elastic element is located inside the housing and abuts against the ejector pin, the ejector pin is movable relative to the housing, a first end of the wire is fixedly connected to and electrically connected to the second end of the ejector pin, and the second end of the wire extends out of the housing.

[0006] Understandably, when the flexible pin assembly is used for electrical signal transmission between the watch band and the watch body, the first end of the pin protrudes outside the housing and can be used for electrical connection to the watch body, while the second end of the wire extends out of the housing and can be used for electrical connection to the watch band body. Electrical signals between the watch body and the watch band body can be transmitted through the first end of the pin, the second end of the pin, the first end of the wire, and the second end of the wire.

[0007] In traditional electrical connection schemes, the pin typically transmits electrical signals out of the housing via a spring. However, when the spring is used for signal transmission, the contact with the pin is unstable and the contact area is small. This problem is particularly pronounced in small wearable devices. Furthermore, the spring is susceptible to corrosion, which significantly reduces its conductivity. In this application, the elastic element does not participate in signal transmission; instead, the pin transmits the signal via a wire. The wire is fixedly connected to the pin, resulting in a more reliable electrical connection between them. Moreover, corrosion of the elastic element does not affect signal transmission, and the elastic pin assembly of this application has lower waterproofing requirements.

[0008] In one possible implementation, the housing includes a top plate, side plates, and a bottom plate, with the side plates connected between the top and bottom plates. The top, side, and bottom plates enclose a receiving space. The top plate has a first through hole that penetrates the top plate and communicates with the receiving space. The bottom plate has a second through hole that penetrates the bottom plate and communicates with the receiving space. The second end of the ejector pin is located within the receiving space, while the first end of the ejector pin protrudes from the top plate of the housing through the first through hole. An elastic element is located within the receiving space and abuts against the ejector pin and the bottom plate. The first end of a wire is electrically connected to the ejector pin within the receiving space, and the second end of the wire extends out of the bottom plate through the second through hole. Thus, the housing provides protection for the ejector pin, the elastic element, and the wire.

[0009] In one possible implementation, the ejector pin includes a baffle, a first end, and a second end. The first end and the second end of the ejector pin are respectively fixedly connected to both sides of the baffle, and the second end of the ejector pin and the baffle are located in a receiving space. An elastic element abuts between the baffle and the bottom plate of the ejector pin, and the baffle abuts against the top plate.

[0010] Understandably, when installing the ejector pin, it can be installed along the direction from the base plate towards the top plate. The ejector pin's baffle can snap into the top plate for quick installation. The elastic element abuts between the ejector pin's baffle and the base plate, allowing the ejector pin's baffle to abut against the top plate, ensuring the ejector pin remains stationary relative to the housing. This prevents the ejector pin from shifting due to external forces and colliding with surrounding structures. Furthermore, when the elastic ejector pin assembly is used for electrical connection between the watch strap and the watch body, the ejector pin remains stationary relative to the watch body. When the watch strap is inserted into the watch body, the ejector pin can quickly and easily align with the terminals of the watch body, thus rapidly establishing an electrical connection between the watch strap and the watch body.

[0011] In one possible implementation, the second end of the ejector pin has a cylindrical structure, and the second end of the ejector pin and the ejector pin baffle enclose an electrical connection space. The first end of the wire extends into the electrical connection space and is electrically connected to the ejector pin.

[0012] Understandably, compared to the solution where the second end of the ejector pin is a solid terminal, in this embodiment, the second end of the ejector pin is a cylindrical structure, and the electrical connection space can be used to accommodate the wire. The first end of the wire can be fixedly connected to the inner side of the second end of the ejector pin, which is beneficial to increasing the contact area between the second end of the ejector pin and the first end of the wire.

[0013] In one possible implementation, the resilient ejector assembly further includes a seal that fills the electrical connection space to seal the electrical connection space.

[0014] Understandably, seals can be used to seal and waterproof electrical connection spaces, preventing external moisture from eroding the electrical connection space and protecting the reliability of the electrical connection between the wires and the pins.

[0015] In one possible implementation, the elastic element is a spring, which is sleeved on the outer periphery of the second end of the ejector pin.

[0016] Understandably, springs are readily available, inexpensive, and have a mature manufacturing process. Using springs as the elastic element can reduce the manufacturing cost of the elastic ejector pin assembly. The elastic element is fitted onto the outer periphery of the second end of the ejector pin, reducing the risk of it wobbling within the flat plate containing the ejector pin. When the elastic ejector pin is subjected to external impact, the elastic element is less likely to displace and leave its preset position.

[0017] In one possible implementation, the housing further includes a partition located within the receiving space and fixedly connected to the side plate, the partition dividing the receiving space into multiple non-communicating sub-spaces. A ejector pin, an elastic element, and a wire constitute an ejector pin assembly; the number of ejector pin assemblies is the same as the number of sub-spaces, with multiple ejector pin assemblies and multiple sub-spaces arranged in a one-to-one correspondence.

[0018] It is understandable that by setting up partitions, multiple ejector pin assemblies are separated into multiple sub-spaces to prevent the elastic ejector pin assemblies from shaking during use, which could cause collisions or interference between multiple ejector pin assemblies, resulting in damage or short circuits.

[0019] In one possible implementation, the top plate, side plates, bottom plate, and partitions are all made of insulating material.

[0020] Understandably, the housing can also be used to insulate the ejector pins within the housing space from external devices, preventing short circuits. When there are multiple ejector pin assemblies, partitions can insulate adjacent ejector pin assemblies, preventing short circuits.

[0021] In one possible implementation, the resilient ejector assembly further includes a metal housing fitted onto the outer periphery of the housing.

[0022] Understandably, when the flexible pin assembly is used for electrical connection between the watch strap and the watch case, and the watch strap is detachably connected to the watch case, the flexible pin assembly will be repeatedly inserted and removed from the watch case, making it prone to collisions with the watch case. The metal casing is made of metal, which is generally harder than plastic or rubber. The metal casing further protects the casing and reduces the risk of damage to the flexible pin assembly.

[0023] In one possible implementation, the resilient ejector pin assembly further includes a waterproof ring fitted over a metal housing.

[0024] Understandably, when the flexible pin assembly is used for electrical connection between the watch strap and the watch body, a waterproof ring can be used to waterproof the gap between the flexible pin assembly and the watch body.

[0025] In one possible implementation, the conductor includes a conductive core and an insulating sheath, the insulating sheath wrapping the conductive core, and the conductive core at the first end of the conductor protruding from the insulating sheath and electrically connected to a pin.

[0026] Understandably, the conductive core is used for electrical signal transmission, while the insulating outer sheath protects the conductive core and insulates it from the external environment, preventing short circuits between the conductive core and external conductive structures. When there are multiple wires, the insulating outer sheath protects the conductive core, preventing contact between the conductive cores of adjacent wires that could lead to a short circuit. The insulating outer sheath also protects the conductive core from corrosion. This results in a more stable electrical transmission path between the pin and the wires.

[0027] Secondly, embodiments of this application provide a watch strap. The watch strap includes a strap body, electronic components, and a flexible pin assembly. The electronic components are disposed on the strap body, a housing is fixedly connected to an end of the strap body, and a second end of a wire is electrically connected to the electronic components.

[0028] Understandably, compared to integrating all electronic components onto the watch body, this application places some electronic components on the watch band and others on the watch body, reducing the size of the watch body and facilitating miniaturization. Without increasing the size of the watch body, additional electronic components can be added to the watch band, integrating more functional devices and enabling the wearable device to have more features, thus improving its versatility and user experience. Furthermore, distributing some of the watch body's weight to the watch band results in a more even weight distribution, preventing the watch from feeling excessively heavy and improving user comfort. The flexible pin assembly can be used for electrical signal transmission between the electronic components on the watch band and the watch body.

[0029] In one possible implementation, the watchband body includes a first link. Electronic components are mounted on the first link. The first link includes a cover and a housing, the housing having a recess recessed toward the inner side of the watchband body, the electronic components being mounted in the recess, and the cover being fixedly connected to the housing and covering the recess.

[0030] Understandably, the cover and the housing work together to protect the electronic components installed inside the housing and prevent damage to them.

[0031] In one possible implementation, the watchband body includes a plurality of first links and second links. A second link is movably connected between two adjacent first links.

[0032] It is understandable that multiple first links can rotate relative to each other, and multiple first links and second links can be arranged along the length of the watch strap, so that the watch strap can have the ability to deform.

[0033] In one possible implementation, the electronic device includes a first electronic device and a second electronic device, which are respectively disposed in two adjacent first links. The watchband body also includes a signal transmission structure, the first end of which is located in the first first link and electrically connected to the first electronic device, and the second end of which passes through the second link, enters the second first link, and is electrically connected to the second electronic device.

[0034] It is understandable that by setting up a signal transmission structure, electrical signal transmission between electronic devices in two first links can be achieved.

[0035] In one possible implementation, the watchband body further includes a signal transmission structure, the first end of which is electrically connected to an elastic pin assembly, and the second end of which passes through a second link, enters the first link, and is electrically connected to electronic devices.

[0036] Understandably, the signal transmission structure can also be used for electrical signal transmission of the resilient ejector pin assembly and the electronic devices within the first link.

[0037] In one possible implementation, the length L1 of the signal transmission structure within the second link is greater than the length L2 of the second link.

[0038] It is understandable that the length L1 of the signal transmission structure within the second link is greater than the length L2 of the second link. This allows for sufficient slack within the second link to support rotation of the second link relative to the first link. The signal transmission structure within the second link will not be stretched due to rotation of the first link relative to the second link, thus preventing signal interruption. The length L2 of the second link refers to its extension along the length of the watch strap.

[0039] In one possible implementation, the relationship between the length L1 of the signal transmission structure within the second link, the length L2 of the second link, and the thickness H of the second link satisfies: L1 - L2 ≥ H.

[0040] Understandably, the length L1 of the signal transmission structure within the second link can be designed based on the length L2 and thickness H of the second link to reduce the risk of electrical connection interruption due to tension on the signal transmission structure when the first and second links rotate relative to each other. The relationship between the length L1 of the signal transmission structure within the second link, the length L2 of the second link, and the thickness H of the second link satisfies: L1 - L2 ≥ H. This effectively ensures that the signal transmission structure has a relatively large margin within the second link.

[0041] In one possible implementation, the watchband body includes a soft rubber strap, with electronic components disposed inside the soft rubber strap. The electronic components are flexible, and / or have a sheet-like structure.

[0042] It is understandable that when a user wears the device, the watch strap bends, and the electronic components can adapt to the bending curvature of the watch strap to avoid damage to the electronic components.

[0043] In one possible implementation, the electronic components include one or more of the following: a battery, a solar panel, an electrocardiogram sensor, an optical volumetric sensor, a pressure sensor, an antenna, a processor, internal memory, a communication module, a camera, an audio module, a speaker, a microphone, a motor, and an indicator. It is understood that the electronic components within the watchband can be designed to meet the user's needs.

[0044] Thirdly, embodiments of this application provide a watch body. The watch body includes a housing and an electrical connection assembly. The housing has a first through hole communicating with the outer space and the inner space of the housing. The housing also includes a protrusion fixed to the wall of the first through hole. The electrical connection assembly includes a circuit board and metal terminals, which are fixed within the first through hole. The circuit board is fixedly connected to the side of the protrusion facing the outer space of the housing, and the metal terminals are fixedly connected to the surface of the circuit board away from the protrusion, with the metal terminals exposed relative to the housing.

[0045] Understandably, in traditional technical solutions, the electrical connection components are installed from the internal space of the casing towards the external space. During the repeated disassembly and assembly of the watch strap and watch body, the pin exerts a force against the metal terminals from the external space towards the internal space, which can easily loosen the connection between the circuit board and the casing, leading to unstable electrical connections. The bump is located on the outside of the circuit board, limiting the insertion depth of the pin and reducing the space available for waterproofing, which is detrimental to waterproofing between the watch strap and watch body. In this embodiment, the electrical connection components are installed along the side of the casing towards the internal space. On one hand, the bump can serve as a positioning structure during installation, facilitating rapid installation; on the other hand, during the repeated disassembly and assembly of the watch strap and watch body, the pin exerts a force against the metal terminals from the external space towards the internal space, making the connection between the circuit board and the casing less prone to loosening, resulting in better reliability of the electrical connection between the watch strap and watch body; furthermore, a larger space can be left within the first through hole for setting up a waterproof structure, which further improves the reliability of the electrical connection between the watch strap and watch body.

[0046] In one possible implementation, the circuit board includes a first side and a second side disposed opposite to each other, with metal terminals fixed to the first side and the second side fixedly connected to a protrusion. The electrical connection assembly also includes a flexible circuit board, one end of which is fixedly connected to the second side of the circuit board and electrically connected to the circuit board, while the other end extends into the internal space of the housing. It is understood that the flexible circuit board can be used to electrically connect internal components and metal terminals of the meter body.

[0047] In one possible implementation, the surface of the metal terminal facing the ejector pin may have a groove (not shown). The groove surface can be designed according to the surface of the first end of the ejector pin, so that when the first end of the ejector pin abuts against the metal terminal, the first end of the ejector pin abuts against the groove surface. For example, the groove surface can be designed as an arc surface.

[0048] Understandably, compared to a design where the surface of the metal terminal facing the ejector pin is flat, increasing the contact area between the metal terminal and the ejector pin by setting a groove helps to reduce resistance and improve the stability of the electrical connection.

[0049] In one possible implementation, the outer casing has a snap-fit ​​groove with its opening located on the bottom surface of the casing. The watch body also includes a retaining component that snaps into the snap-fit ​​groove. The outer casing has a second through hole that connects the groove surface of the snap-fit ​​groove and the side surface of the outer casing.

[0050] Understandably, when the watch strap is detachably connected to the watch case, the retaining component engages with the strap to secure the strap and the watch case. The strap can enter the retaining slot through the second through hole and engage with the retaining component. The retaining component can be used for the detachable connection between the strap and the watch case.

[0051] Fourthly, embodiments of this application provide a wearable device. The wearable device includes a watch body and a watch strap provided in the second aspect. The watch strap is detachably connected to the watch body, and when the watch strap is connected to the watch body, a pin is electrically connected to the watch body.

[0052] Understandably, the watch band includes a flexible pin assembly, which offers superior electrical connection reliability, thus ensuring a reliable electrical connection between the watch band and the watch body. Electronic components can be integrated into the watch band, and wearable devices can incorporate even more electronic components, enhancing their multi-functionality.

[0053] In one possible implementation, when the watch strap is not connected to the watch body, the first end of the pin protrudes from the housing by a first protrusion height H1; when the watch strap is connected to the watch body, the first end of the pin protrudes from the housing by a second protrusion height H2. The second protrusion height H2 is less than the first protrusion height H1.

[0054] Understandably, when the watch strap is connected to the watch body, the elastic element is compressed, giving the pin a supporting force towards the watch body. The pin moves relative to the housing, and the first end of the pin abuts against and is electrically connected to the metal terminal.

[0055] Fifthly, embodiments of this application provide a wearable device. The wearable device includes a watch strap and a watch body provided in the third aspect. The watch strap is detachably connected to the watch body, and when the watch strap is connected to the watch body, the watch strap is electrically connected to metal terminals.

[0056] Understandably, the watch body includes the outer casing and electrical connection components. During the repeated assembly and disassembly of the watch band and watch body, the watch band provides external force to the metal terminals, preventing the connection between the circuit board and the outer casing from loosening and ensuring reliable electrical connection between the watch band and watch body. The watch band can electrically connect to metal terminals, and there can be an electrical connection structure between the watch band and the watch body. Electronic components can be mounted on the watch band, allowing for more electronic components in wearable devices, thus promoting multifunctionality. Attached Figure Description

[0086] The embodiments of this application are described below with reference to the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0087] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in this application, "electrical connection" can be understood as components physically contacting and conducting electricity; it can also be understood as a form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A connecting to B or A being connected to B can mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0088] Furthermore, the term "fixed" in this document should be interpreted broadly. For example, "fixed" can mean direct fixing or indirect fixing through an intermediate medium. "Fixed" refers to connections where the relative positional relationship remains unchanged after connection. The directional terms used in the embodiments of this application, such as "upper" and "lower," are merely for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to two or more.

[0089] In the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0090] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0091] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0092] It is understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. It should also be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0093] Figure 1 is a structural schematic diagram of one embodiment of the wearable device 1000 provided in this application. Figure 2 is an exploded schematic diagram of one embodiment of the wearable device 1000 shown in Figure 1.

[0094] Wearable device 1000 can be a watch or a bracelet. Figure 1 illustrates wearable device 1000 using a watch as an example. It should be noted that Figures 1 and 2 only schematically show some components of wearable device 1000; the actual size, location, and structure of these components are not limited by the figures. The accompanying figures below also only schematically show some components; the actual size, location, and structure of these components are not limited by the accompanying figures. Specific details will not be elaborated further below.

[0095] As shown in Figures 1 and 2, the wearable device 1000 may include a watch strap 100 and a watch body 200. The watch strap 100 is connected to the watch body 200. Exemplarily, there may be one watch strap 100, in which both ends of the watch strap 100 are connected to both ends of the watch body 200. When a user wears the wearable device 1000, the watch strap 100 can be used to secure the watch body 200 to the user. In other embodiments, there may be two watch straps 100, wherein one end of each watch strap is used to connect to the watch body 200, and the other end is used to connect to another watch strap.

[0096] The watch strap 100 can be detachably connected to the watch body 200. This means that when the watch strap 100 becomes dirty or damaged, only the watch strap 100 needs to be replaced, without needing to replace the entire wearable device 1000. The following section will describe in detail the implementation of the detachable connection of the watch strap 100 to the watch body 200 with reference to the accompanying drawings.

[0097] The watch band 100 may include electronic components 21, which are schematically shown in FIG2 by dashed boxes. Exemplarily, the electronic components 21 of the watch band 100 may include one or more of the following: a battery, a solar panel, an electrocardiography (ECG) sensor, a photoplethysmograph (PPG) sensor, a pressure sensor, an antenna, a processor, internal memory, a communication module, a camera, an audio module, a speaker, a microphone, a motor, and an indicator.

[0098] In some embodiments, the watch body 200 may include electronic devices 212, which are schematically illustrated by dashed boxes in Figure 2. The electronic devices 212 of the watch body 200 may include one or more of the following: a battery, a solar panel, an electrocardiogram (ECG) sensor, a photoplethysmograph (PPG) sensor, a pressure sensor, an antenna, a processor, internal memory, a communication module, a camera, an audio module, a speaker, a microphone, a motor, and an indicator. It should be noted that the types and numbers of electronic devices 212 included in the watch strap 100 and the watch body 200 may be the same or different.

[0099] Understandably, compared to integrating all electronic components onto the watch body 200, this application places a portion of the electronic components of the wearable device 1000 on the watch band 100, which reduces the size of the watch body 200 and facilitates miniaturization of the wearable device 1000. Without increasing the size of the watch body 200, additional electronic components 21 can be added to the watch band 100, integrating more functional components and allowing the wearable device 1000 to have more functions, thus enhancing its multi-functionality and improving the user experience. Furthermore, by distributing a portion of the weight of the watch body 200 to the watch band 100, the weight distribution of the wearable device 1000 is more even, preventing the watch body 200 from feeling excessively heavy and improving the user experience.

[0100] When some electronic components of the wearable device 1000 are located on the watch band 100 and some are located on the watch body 200, the wearable device 1000 can be equipped with an electrical connection structure for electrical signal transmission between the electronic components 21 of the watch band 100 and the electronic components 212 of the watch body 200. Taking the battery as an example, by placing the battery on the watch band 100, the larger space in the watch band 100 allows for a larger battery, thereby enabling the wearable device 1000 to have a longer battery life.

[0101] In some embodiments, the material of the watch strap 100 may include, but is not limited to, metal, leather, rubber, ceramic, and nylon. Figures 1 and 2 illustrate examples where the watch strap 100 is made of metal. The following will describe several different implementations of electrical connection between the watch strap 100 and the watch body 200, in conjunction with the accompanying drawings.

[0102] Figure 3 is an exploded view of one embodiment of the watch strap 100 shown in Figure 2.

[0103] As shown in Figures 2 and 3, the watch strap 100 may further include a flexible pin assembly 10 and a watch strap body 20. The flexible pin assembly 10 is fixedly connected to the watch strap body 20. The flexible pin assembly 10 is used to transmit electrical signals. The watch strap 100 may also include an electronic device 21 (illustrated by a dashed box in the figures), which may be disposed on the watch strap body 20. The flexible pin assembly 10 can be used for electrical signal transmission between the electronic device 21 of the watch strap 100 and the electronic device 212 of the watch body 200.

[0104] It is understood that the watch strap 100 has two opposing ends, and each end of the watch strap can be provided with a resilient pin assembly 10. Figure 3 illustrates two resilient pin assemblies 10.

[0105] Figure 4 is a structural schematic diagram of one embodiment of the elastic ejector assembly 10 shown in Figure 3. Figure 5 is an exploded schematic diagram of one embodiment of the elastic ejector assembly 10 shown in Figure 4.

[0106] As shown in Figures 3 to 5, the resilient pin assembly 10 may include a pin 1, an elastic element 2, a wire 3, and a housing 4. The pin 1 may protrude from the housing 4 for electrical connection to the watch body 200. The wire 3 may extend from the housing 4 for electrical connection to the watch band body 20. Exemplarily, the wire 3 may extend from the housing 4 for electrical connection to electronic components 21 within the watch band body 20.

[0107] Figure 6 is a structural schematic diagram of one embodiment of the ejector pin 1 shown in Figure 5.

[0108] As shown in Figure 6, the ejector pin 1 includes a baffle 11, a first end 12, and a second end 13. The first end 12 and the second end 13 of the ejector pin 1 are respectively fixedly connected to both sides of the baffle 11. Exemplarily, the second end 13 of the ejector pin 1 has a cylindrical structure, and the second end 13 of the ejector pin 1 and the baffle 11 enclose an electrical connection space 14.

[0109] In some embodiments, the ejector pin 1 can be made of metallic materials such as copper and copper alloys. This results in the ejector pin 1 having good conductivity and strength, and the raw materials are readily available and inexpensive.

[0110] Figure 7 is a cross-sectional view of one embodiment of the elastic ejector assembly 10 shown in Figure 4 at point AA. In Figure 7, the rightmost ejector 1 is schematically distinguished by dashed lines from the baffle 11, the first end 12, and the second end 13.

[0111] As shown in Figure 7, the first end 12 of the ejector pin 1 protrudes outside the housing 4. The second end 13 of the ejector pin 1 is located inside the housing 4. The elastic element 2 is located inside the housing 4 and abuts against the ejector pin 1. The ejector pin 1 is movable relative to the housing 4. The first end 31 of the wire 3 is fixedly connected to and electrically connected to the second end 13 of the ejector pin 1, and the second end 32 of the wire 3 extends out of the housing 4.

[0112] As can be understood, referring to Figures 2 and 7, when the elastic pin assembly 10 is used for electrical signal transmission between the watch band body 20 and the watch body 200, the first end 12 of the pin 1 protrudes outside the housing 4 and can be used to electrically connect to the watch body 200, and the second end 32 of the wire 3 protrudes from the housing 4 and can be used to electrically connect to the watch band body 20. The electrical signal between the watch body 200 and the watch band body 20 can be transmitted through the first end 12 of the pin 1, the second end 13 of the pin 1, the first end 31 of the wire 3, and the second end 32 of the wire 3.

[0113] In traditional electrical connection schemes, the pin 1 typically transmits electrical signals out of the housing 4 via a spring. However, when the spring is used for signal transmission, the contact with the pin 1 is unstable, and the contact area is small. This problem is particularly pronounced in small wearable devices like the 1000. Furthermore, the spring is susceptible to corrosion, which significantly reduces its conductivity. In this application, the elastic element 2 does not participate in signal transmission; the pin 1 transmits electrical signals via a wire 3. The wire 3 is fixedly connected to the pin 1, resulting in a more reliable electrical connection between the wire 3 and the pin 1. Moreover, corrosion of the elastic element 2 does not affect signal transmission, and the elastic pin assembly 10 of this application has lower waterproofing requirements.

[0114] In some embodiments, the housing 4 includes a top plate 41, a side plate 42, and a bottom plate 43, with the side plate 42 connected between the top plate 41 and the bottom plate 43. The top plate 41, side plate 42, and bottom plate 43 enclose a receiving space 44. The top plate 41 has a first through hole 411 that penetrates the top plate 41 and communicates with the receiving space 44. The bottom plate 43 has a second through hole 431 that penetrates the bottom plate 43 and communicates with the receiving space 44. The second end 13 of the ejector pin 1 is located within the receiving space 44. The first end 12 of the ejector pin 1 protrudes from the top plate 41 of the housing 4 through the first through hole 411. The first end 31 of the wire 3 is electrically connected to the ejector pin 1 within the receiving space 44. The second end 32 of the wire 3 extends out of the bottom plate 43 through the second through hole 431. In this way, the housing 4 can protect the ejector pin 1, the elastic element 2, and the wire 3.

[0115] In some embodiments, the second end 13 of the ejector pin 1 and the baffle 11 can be located in the receiving space 44. The first end 12 of the ejector pin 1 can extend out of the top plate 41 through the first through hole 411. It is understood that by setting the size and / or cross-sectional shape of the baffle 11 of the ejector pin 1 and the size and / or cross-sectional shape of the first through hole 411 to be different, the ejector pin 1 can be installed along the direction from the bottom plate 43 toward the top plate 41, with the baffle 11 of the ejector pin 1 snapping into the top plate 41, to achieve quick installation. For example, taking the cross-sectional shape of the baffle 11 and the cross-sectional shape of the first through hole 411 as both being circular, the diameter of the baffle 11 of the ejector pin 1 can be set to be larger than the diameter of the first end 12 of the ejector pin 1, and the diameter of the first through hole 411 is larger than the diameter of the first end 12 of the ejector pin 1, but smaller than the diameter of the baffle 11 of the ejector pin 1.

[0116] In some embodiments, the first end 31 of the wire 3 is fixedly connected to the second end 13 of the ejector pin 1 to achieve an electrical connection to the second end 13 of the ejector pin 1. Exemplarily, the first end 31 of the wire 3 can be fixedly connected to the second end 13 of the ejector pin 1 by welding, and thus electrically connected to the second end 13 of the ejector pin 1. In other embodiments, the first end 31 of the wire 3 can also be fixedly connected to the baffle 11 of the ejector pin 1 simultaneously. In other embodiments, during the manufacturing process, the second end 13 of the ejector pin 1 is clamped using pliers or other clamps, causing the second end 13 of the ejector pin 1 to deform and clamp the first end 31 of the wire 3, thereby fixing the wire 3 and the ejector pin 1 together. This application does not limit the method of fixing the wire 3 and the ejector pin 1.

[0117] For example, the second end 13 of the ejector pin 1 and the baffle 11 of the ejector pin 1 enclose an electrical connection space 14, and the first end 31 of the wire 3 can extend into the electrical connection space 14 and be electrically connected to the ejector pin 1. It can be understood that, compared with the scheme where the second end 13 of the ejector pin 1 is a solid terminal, in this embodiment, the second end 13 of the ejector pin 1 has a cylindrical structure, and the electrical connection space 14 can be used to accommodate the wire 3. The first end 31 of the wire 3 can be fixedly connected to the inner side of the second end 13 of the ejector pin 1, which is beneficial to increasing the contact area between the second end 13 of the ejector pin 1 and the first end 31 of the wire 3.

[0118] In some embodiments, the conductor 3 may include a conductive core 31 and an insulating sheath 32. The insulating sheath 32 encloses the conductive core 31, with one end of the conductive core 31 protruding from the insulating sheath 32 and electrically connected to the pin 1. Figure 7 illustrates the conductive core 31 and insulating sheath 32 using the leftmost conductor 3 as an example; the other conductors 3 in Figure 7 have the same structure. It is understood that the conductive core 31 can be used for electrical signal transmission, and the insulating sheath 32 can protect the conductive core 31 and insulate it from the outside environment, preventing short circuits between the conductive core 31 and external conductive structures. When there are multiple conductors 3, the insulating sheath 32 protects the conductive core 31, preventing contact between the conductive cores 31 of adjacent conductors 3, which could lead to short circuits. The insulating sheath 32 also protects the conductive core 31 from corrosion. The electrical transmission path between the pin 1 and the conductors 3 is more stable.

[0119] In some embodiments, as shown in Figures 6 and 7, the resilient ejector pin assembly 10 further includes a seal 5. The seal 5 fills the electrical connection space 14 to seal the electrical connection space 14. It is understood that the seal 5 can be used to seal and waterproof the electrical connection space 14, preventing external moisture from corroding the electrical connection space 14 and protecting the reliability of the electrical connection between the wire 3 and the ejector pin 1.

[0120] For example, the seal 5 can be cured from a waterproof adhesive. In this way, the seal 5 can not only waterproof the electrical connection space 14, but also enhance the connection strength between the first end 31 of the wire 3 and the second end 13 of the pin 1, further improving the reliability of the electrical connection between the first end 31 of the wire 3 and the second end 13 of the pin 1. In other embodiments, the seal 5 can also be made of other waterproof materials.

[0121] In some embodiments, the elastic element 2 is located within the receiving space 44. The elastic element 2 abuts between the ejector pin 1 and the base plate 43. The ejector pin 1 and the base plate 43 may be spaced apart. It is understood that when the ejector pin 1 is subjected to a force along the direction from the top plate 41 toward the base plate 43, the ejector pin 1 moves toward the direction closer to the base plate 43, the ejector pin 1 moves relative to the housing 4, the elastic element 2 is compressed, and the ejector pin 1 is given room to move.

[0122] In some embodiments, the elastic element 2 abuts against the baffle 11 of the ejector pin 1 and the base plate 43, allowing the baffle 11 of the ejector pin 1 to abut against the top plate 41. This allows the ejector pin 1 to remain stationary relative to the housing 4, preventing it from shifting relative to the housing 2 due to external forces and colliding with surrounding structures. Furthermore, when the elastic ejector pin assembly 10 is used for electrical connection between the watch strap 100 and the watch body 200, the ejector pin 1 remains stationary relative to the watch body 200. When the watch strap 100 is inserted into the watch body 200, the ejector pin 1 can quickly and easily align with the terminals of the watch body 200, thus rapidly establishing an electrical connection between the watch strap 100 and the watch body 200.

[0123] Understandably, when the watch strap 100 is not installed on the watch body 200, the elastic element 2 may or may not abut against the pin 1 and the base plate 43. When the watch strap 100 is installed on the watch body 200, the elastic element 2 is compressed and abuts against the baffle 11 of the pin 1 and the base plate 43. When the watch strap 100 is not installed on the watch body 200, the baffle 11 of the pin 1 may just touch the top plate 41, but there is no abutment between the two. This can be achieved by adjusting the length of the elastic element 2, the distance between the top plate 41 and the base plate 43, and the size of the baffle 11 of the pin 1.

[0124] In some embodiments, the elastic element 2 can be a spring. The elastic element 2 is sleeved on the outer periphery of the second end 13 of the ejector pin 1. It is understood that the manufacturing process of springs is mature, readily available, and inexpensive. Using a spring as the elastic element 2 can reduce the manufacturing cost of the elastic ejector pin assembly 10. The elastic element 2 being sleeved on the outer periphery of the second end 13 of the ejector pin 1 can reduce the risk of the elastic element 2 swaying within the plane of the top plate 41. When the elastic ejector pin 1 is subjected to external impact, the elastic element 2 is less likely to displace and leave its preset position. In other embodiments, the elastic element 2 can also be a continuous Z-shaped spring or similar structure; this application does not limit the specific shape of the elastic element 2.

[0125] In some embodiments, the elastic element 2 can be detachably connected between the ejector pin 1 and the housing 4. This facilitates the disassembly and maintenance of the elastic ejector pin assembly 10. In other embodiments, the elastic element 2 can also be fixedly connected between the ejector pin 1 and the housing 210. For example, the elastic element 2 can be fixedly connected to the ejector pin 1 and the housing 210 by welding.

[0126] For example, a pin 1, an elastic element 2, and a wire 3 constitute a pin assembly 6. The elastic pin assembly 10 may include one or more pin assemblies 6. When the elastic pin assembly 10 includes multiple pin assemblies 6, the multiple pin assemblies 6 are spaced apart. The accompanying drawings illustrate five sets of pin assemblies 6. It is understood that the elastic pin assembly 10 may include multiple pin assemblies 6; one pin assembly 6 can be used to transmit one signal, and multiple pin assemblies 6 can be used to transmit multiple signals. The elastic pin assembly 10 is suitable for scenarios requiring the transmission of multiple signals.

[0127] For example, as shown in Figures 7 and 3, multiple ejector pin assemblies 6 can be spaced apart along the width direction of the watch strap body 20. The length direction of the ejector pin 1 can be the same as the length direction of the housing 4. The length direction of the housing 4 is the direction from the bottom plate 43 to the top plate 41. In this way, compared with the scheme in which multiple ejector pin assemblies 6 are spaced apart along the thickness direction of the watch strap body 20, multiple ejector pin assemblies 6 can be spaced apart along the width direction of the watch strap body 20, which allows for the installation of a larger number of ejector pin assemblies 6 without increasing the thickness of the watch strap body 20, thus facilitating the thinning of the watch strap 100.

[0128] In some embodiments, the housing 4 further includes a partition 45. The partition 45 may be located within the receiving space 44 and fixedly connected to the side plate 42. The partition 45 divides the receiving space 44 into multiple non-communicating sub-spaces 441. The number of ejector pin assemblies 6 may be the same as the number of sub-spaces 441, with multiple ejector pin assemblies 6 and multiple sub-spaces 441 arranged in a one-to-one correspondence. It is understood that by setting the partition 45, the multiple ejector pin assemblies 6 are separately arranged in multiple sub-spaces 441, avoiding the wearable device 1000 from shaking when the user is using it, causing the elastic ejector pin assemblies 10 to shake, which could lead to collision interference between the multiple ejector pin assemblies 6, resulting in damage or short circuit.

[0129] In some embodiments, the top plate 41, side plate 42, bottom plate 43, and partition 45 can all be made of insulating material, such as plastic or rubber. Thus, the housing 4 can also insulate the ejector pins 1 within the receiving space 44 from external devices, preventing short circuits. When there are multiple ejector pin assemblies 6, the partition 45 can insulate adjacent ejector pin assemblies 6 from short circuits.

[0130] For example, the top plate 41 and the side plate 42 can be integrally molded structural components. The top plate 41 and the side plate 42 are non-detachably connected, resulting in good connection strength. The integral molding process of the two components to form an integrated structure means that during the formation of one of the components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to join the two components together. For example, the top plate 41 and the side plate 42 can be formed into an integral structure using injection molding.

[0131] For example, the side plate 42 and the partition plate 45 can also be integrally formed structural components. The side plate 42 and the partition plate 45 are not detachably connected, and the connection strength is better.

[0132] For example, the base plate 43 can be fixedly connected to the side plate 42 by adhesive. In this way, when it is necessary to install the ejector pin 1, the elastic element 2, and the wire 3, the ejector pin 1, the elastic element 2, and the wire 3 are first installed into the receiving space 44, and then the base plate 43 is fixedly connected to the side plate 42. Installation is convenient.

[0133] In some embodiments, the resilient pin assembly 10 further includes a metal housing 7, which is fitted onto the outer periphery of the housing 4. It is understood that since the watch strap 100 is detachably connected to the watch body 200, when the resilient pin assembly 10 is used for electrical connection between the watch strap 100 and the watch body 200, the resilient pin assembly 10 will undergo multiple insertions and removals from the watch body 200, making it prone to collisions. The metal housing 7 is made of metal, which is generally harder than plastic or rubber. The metal housing 7 further protects the housing 4 and reduces the risk of damage to the resilient pin assembly 10.

[0134] In some embodiments, the resilient pin assembly 10 further includes a waterproof ring 8, which is fitted onto the metal housing 7. When the watch strap 100 is connected to the watch body 200, the waterproof ring 8 can be used for waterproofing between the watch strap 100 and the watch body 200, as will be described in detail below with reference to the accompanying drawings.

[0135] Figure 8 is a partial structural schematic diagram of one embodiment of the watch strap 100 shown in Figure 2. Figure 9 is an exploded schematic diagram of one embodiment of the partial structure shown in Figure 8. Figure 10 is a partial structural schematic diagram of one embodiment of the watch strap 100 shown in Figure 8. Figures 8 to 10 illustrate a metal watch strap 100 as an example.

[0136] As shown in Figures 8 to 10, the housing 4 of the elastic pin assembly 10 can be fixedly connected to the end of the watchband body 20. Electronic components are disposed on the watchband body 20. Exemplarily, the watchband body 20 may include a first link 201 and a head link 202, the first link 201 being used to mount the electronic component 21. The elastic pin assembly 10 can be fixedly connected to the head link 202. The head link 202 is movably connected to the first link 201.

[0137] In some embodiments, the resilient ejector assembly 10 can be fixedly connected to the head link 202 by screws. Exemplarily, the metal housing 7 of the resilient ejector assembly 10 can be fixedly connected to the head link 202 by screws. It is understood that the metal housing 7 has good strength, can be fixed with screws, and is not easily deformed.

[0138] In some embodiments, the head link 202 has a first end face 2021, and the resilient pin assembly 10 protrudes from the first end face 2021. The first end 12 of the pin 1 of the resilient pin assembly 10 extends out of the first end face 2021 for electrical connection with the watch body 200. The second end 32 of the wire 3 extends into the head link 202 and is electrically connected to the electronic components on the watch strap 100.

[0139] In some embodiments, the head link 202 may include a hook 2022 protruding from the first end face 2021. The hook 2022 can be used for engaging the head connection and the strap 100.

[0140] In some embodiments, the watch strap body 20 may further include a buffer 203. The buffer 203 may be fixedly connected to the first end face 2021 of the head link 202. The buffer 203 may be spaced apart from the hook 2022. The buffer 203 is flexible and deformable. For example, the material of the buffer 203 may be a flexible material such as silicone.

[0141] For example, the head link 202 may have a curvature along the length of the strap 100. In this way, the head link 202 can better adapt to the curvature of the user's wrist.

[0142] In some embodiments, the first link 201 includes a cover plate 2011 and a housing 2012. The housing 2012 has a recess 2013 recessed towards the inside of the watch strap body 20, in which electronic components 21 are mounted. The cover plate 2011 is fixedly connected to the housing 2012 and covers the recess 2013. It is understood that the cooperation between the cover plate 2011 and the housing 2012 can protect the electronic components 21 mounted in the housing 2012 from damage.

[0143] For example, the cover plate 2011 can be fixedly connected to the housing 2012 by screws. The gap between the cover plate 2011 and the housing 2012 can also be glued / applied to form a waterproof component 2015 for waterproofing, protecting the electronic components 21 inside the first link 201 from moisture corrosion.

[0144] In some embodiments, the number of first links 201 can be one or more. When there are multiple first links 201, the watch strap body 20 may further include a second link 204, which is movably connected between two adjacent first links 201. This allows the multiple first links 201 to rotate relative to each other, and the multiple first links 201 and second links 204 can be arranged along the length of the watch strap 100, enabling the watch strap 100 to have deformability. For example, the second link 204 can be movably connected between two adjacent first links 201 via a pivot 207.

[0145] For example, the relative rotation angle between the first link 201 and the second link 204 can be in the range of 50° to 70°. For example, 50°, 55°, 60°, 65° or 70°. In this way, the watch strap 100 can fit the user's wrist better, resulting in a better user experience.

[0146] For example, the first link 201 has a first abutting surface 2014 facing the second link 204. The second link 204 has a second abutting surface 2041 facing the first link 201. It is understood that when the watch strap 100 is approximately 180° along its length, the first abutting surface 2014 and the second abutting surface 2041 are angled together along the length of the watch strap 100. When the first link 201 and the second link 204 are rotatably connected, after the first link 201 rotates relative to the second link 204 by a certain angle, the first abutting surface 2014 can abut against the second abutting surface 2041, thereby stopping the rotation of the first link 201 and the second link 204.

[0147] It is understood that the relative rotation angle between the first abutment surface 2014 and the second abutment surface 2041 can be controlled by setting the included angle between them. The second link 204 may include a plurality of second abutment surfaces 2041, so that it can cooperate with the first abutment surfaces 2014 of two adjacent first links 201.

[0148] In other embodiments, the two first links 201 can also be directly rotatably connected. When the two first links 201 are directly connected, the two first links 201 can also be provided with two opposing abutment surfaces at an included angle to control the relative rotation angle of the two first links 201.

[0149] In some embodiments, the watchband body 20 may further include a signal transmission structure 205. The signal transmission structure 205 may be disposed inside the watchband body 20 for electrical signal transmission between electronic devices 21 inside the two watchband bodies 20, or for electrical signal transmission between the elastic pin assembly 10 and the electronic devices 21 inside the watchband body 20.

[0150] For example, the electronic components 21 of the watchband 100 may include a first electronic component 211 and a second electronic component 212, which are respectively disposed in two adjacent first links 201. A portion of the signal transmission structure 205 may be located in the first first link 201 and electrically connected to the first electronic component 211, while another portion of the signal transmission structure 205 passes through the second link 204 and enters the second first link 201, where it is electrically connected to the second electronic component 212. It is understood that by providing the signal transmission structure 205, electrical signal transmission between the electronic components 21 in the two first links 201 can be achieved.

[0151] It is understood that the first electronic device 211 within the first first link 201 may include one or more functional devices. When the first first link 201 includes multiple functional devices, the device types may be one or more. For example, the first electronic device 211 may include a pressure sensor and a PPG sensor. The arrangement of the second electronic device 212 within the second first link 201 can refer to the arrangement of the first electronic device 211 within the first first link 201.

[0152] For example, a portion of the signal transmission structure 205 may be electrically connected to the resilient ejector assembly 10, and a portion may pass through the second link 204, enter the first link 201, and be electrically connected to electronic devices. It is understood that the signal transmission structure 205 may also be used for electrical signal transmission between the resilient ejector assembly 10 and the electronic devices within the first link 201.

[0153] In some embodiments, the length L1 of the signal transmission structure 205 within the second link 204 is greater than the length L2 of the second link 204. This allows for sufficient slack within the second link 204 to support rotation of the second link 204 relative to the first link 201, preventing the signal transmission structure 205 from being stretched due to rotation of the first link 201 relative to the second link 204, thus avoiding signal interruption. The length L2 of the second link 204 refers to its length along the length direction of the watch strap 100.

[0154] In some embodiments, the length L1 of the signal transmission structure 205 within the second link 204 can be designed based on the length L2 and thickness H of the second link 204 to reduce the risk of electrical connection interruption caused by the signal transmission structure 205 being stretched when the first link 201 and the second link 204 rotate relative to each other. For example, the relationship between the length L1 of the signal transmission structure 205 within the second link 204, the length L2 of the second link 204, and the thickness H of the second link 204 satisfies: L1 - L2 ≥ H. This effectively ensures that the signal transmission structure 205 has a relatively large margin within the second link 204.

[0155] For example, the relationship between the length L1 of the signal transmission structure 205 within the second link 204, the length L2 of the second link 204, and the thickness H of the second link 204 can also satisfy: 0.9H ≤ L1 - L2 ≤ 1.2H. For example, the difference between L1 and L2 can be 0.9H, 1.0H, 1.1H, 1.2H, etc. In this way, the margin of the signal transmission structure 205 within the second link 204 is within a suitable range, which can accommodate the relative rotation of the first link 201 and the second link 204 without being too long, thus requiring a large accommodating space 44.

[0156] Figure 11 is a partial cross-sectional view of one embodiment of the structure shown in Figure 10 at BB.

[0157] As shown in Figures 9 to 11, the second link 204 may include a first cover 2042 and a first frame 2043. The first frame 2043 is rotatably connected to the second link 204. The first frame 2043 has a first channel 2044, which can be used to accommodate the signal transmission structure 205. The first cover 2042 is fixedly connected to the first frame 2043 and is used to cover the first channel 2044. The cooperation of the first cover 2042 and the first frame 2043 allows the signal transmission structure 205 to be routed within the second link 204, which not only protects the signal transmission structure 205 but also makes the appearance of the watch strap 100 consistent. The user cannot see the signal transmission structure 205 from the outside of the watch strap 100, which helps to improve the aesthetics of the watch strap 100.

[0158] In some embodiments, the signal transmission structure 205 may include a first circuit board 2051, a second circuit board 2052, a signal line 2053, and a flexible circuit board 2054. A first space 2024 may be provided inside the head link 202. The first circuit board 2051 is mounted in the first space 2024. The second end 32 of the wire 3 of the elastic pin assembly 10 extends out of the housing 4, enters the first space 2024 of the head link 202, and is electrically connected to the first circuit board 2051. The watchband body 20 may also include a third link 206. The third link 206 may be movably connected between the first link 201 and the head link 202. The third link 206 may have a second cover 2061 and a second frame 2062. The second cover 2061 and the second frame 2062 may enclose a second space 2063. The second circuit board 2052 is mounted in the second space 2063. One end of the flexible circuit board 2054 is located in the first space 2024 and electrically connected to the first circuit board 2051, while the other end is located in the second space 2063 and electrically connected to the second circuit board 2052. One end of the signal line 2053 is located in the second space 2063 and electrically connected to the second circuit board 2052, while the other end enters the first link 201 and is electrically connected to an electronic device. The signal line 2053 can extend directly from the third link 206 and enter the first link 201; it can also extend from the third link 206, pass through the first channel 2044 of the second link 204, and enter the first link 201; or it can extend from the first link 201, pass through the first channel 2044 of the second link 204, and enter the second link 201.

[0159] Understandably, compared to the solution where the elastic pin 1 directly contacts and electrically connects to the circuit board to draw out electrical signals, in the technical solution of this application, the electrical signals of the pin 1 can be transmitted through the wire 3 from the elastic pin assembly 10 and enter the inside of the watchband body 20, electrically connecting to the electronic device 21. The length of the wire 3 can be set to be longer, and the volume of the wire 3 is smaller, with less space limitation, making it more suitable for small-volume devices. The installation position of the first circuit board 2051 is more flexible and is not limited to the position of the base plate 43 of the elastic pin assembly 10.

[0160] It is understood that the signal transmission structure 205 described in the foregoing embodiments may include a first circuit board 2051, a second circuit board 2052, a signal line 2053, and a flexible circuit board 2054. This is only one example of the signal transmission structure 205, and the signal transmission structure 205 may also include more or fewer structures. This application does not limit the specific arrangement of the signal transmission structure 205. For example, the signal transmission structure 205 may not include the first circuit board 2051 and the flexible circuit board 2054, and the second end 32 of the wire 3 of the elastic ejector assembly 10 may extend out of the housing 4, pass through the head link 202, and enter the first link 201.

[0161] For example, the first circuit board 2051 and the second circuit board 2052 may be provided with electronic components such as choke inductors and switches.

[0162] For example, the first circuit board 2051 and the second circuit board 2052 can be printed circuit boards (PCBs).

[0163] In some embodiments, the signal transmission structure 205 includes a signal line 2053. When the signal line 2053 passes through the second link 204 for electrical transmission, the length L of the signal line 2053 within the second link 204 is greater than the length L2 of the second link 204. This allows for sufficient length of the signal line 2053 within the second link 204 to support rotation of the second link 204 relative to the first link 201, preventing the signal from being interrupted due to tension caused by rotation of the first link 201 relative to the second link 204.

[0164] For example, the relationship between the length L1 of the signal line 2053 within the second link 204, the length L2 of the second link 204, and the thickness H of the second link 204 satisfies: L1 - L2 ≥ H. This effectively ensures that the signal line 2053 has a relatively long margin within the second link 204.

[0165] For example, the relationship between the length L1 of the signal line 2053 within the second link 204, the length L2 of the second link 204, and the thickness H of the second link 204 can also satisfy: 0.9H ≤ L1 - L2 ≤ 1.2H. For example, the difference between L1 and L2 can be 0.9H, 1.0H, 1.1H, 1.2H, etc.

[0166] Figure 12 is a partially exploded view of one embodiment of the body 200 shown in Figure 2.

[0167] As shown in Figure 12, the watch body 200 may include a housing 210, an electrical connection assembly 220, a holding assembly 230, and a display screen 240. The display screen 240 may be fixedly connected to the housing 210. The housing 210 may have an enclosed accommodating space 2109 inside, and the electronic components 212 of the watch body 200 may be disposed within the accommodating space 2109 or disposed on the housing 210.

[0168] In other embodiments, the watch body 200 may not have a display function. For example, the position of the display screen 240 may be replaced by the front cover of the housing 210.

[0169] Figure 13 is a structural schematic diagram of one embodiment of the housing 210 shown in Figure 12. Figure 14 is a partial cross-sectional view of one embodiment of the housing 210 shown in Figure 13 at CC.

[0170] As shown in Figures 12 to 14, the outer casing 210 may include a middle frame 2101 and a back casing 2102. The middle frame 2101 may be connected between the back casing 2102 and the display screen 240. The middle frame 2101 may be arranged in a ring around the display screen 240. Along the thickness direction of the casing 200, the back casing 2102 is disposed opposite to the display screen 240. When the wearable device 1000 is worn, the back casing 2102 may contact the user's wrist. Exemplarily, the outer casing 210 may include a side surface 2107 and a bottom surface 2105. The bottom surface 2105 of the outer casing 210 is the surface of the back casing 2102 that is away from the middle frame 2101. The side surface 2107 of the outer casing 210 may be the surface of the middle frame 2101 that is away from the receiving space 2109. When the user uses the wearable device 1000, the bottom surface 2105 of the outer casing 210 faces the user's skin.

[0171] In some embodiments, the middle frame 2101 and the rear shell 2102 can be integrally molded structural components. For example, the middle frame 2101 and the rear shell 2102 can both be made of the same material, such as plastic, and can be integrally molded by injection molding; or, the middle frame 2101 and the rear shell 2102 can include both plastic and metal materials, and can be integrally molded by insert injection molding. In other embodiments, the middle frame 2101 and the rear shell 2102 can also be two detachable structural components.

[0172] In some embodiments, the housing 210 may be provided with a first through hole 2103. The first through hole 2103 may connect the external space and the internal space of the housing 210. For example, the first through hole 2103 may penetrate the middle frame 2101.

[0173] In some embodiments, the housing 210 may also be provided with a snap-fit ​​groove 2104. The opening of the snap-fit ​​groove 2104 may be located on the bottom surface 2105 of the housing 210. The housing 210 may also be provided with a second through hole 2106, which connects the groove surface of the snap-fit ​​groove 2104 and the side surface 2107 of the housing 210. For example, the opening of the second through hole 2106 may be located on the middle frame 2101.

[0174] In other embodiments, the opening of the snap-fit ​​groove 2104 may also be located on the top surface or other surface of the housing 210.

[0175] Figure 15 is a structural schematic diagram of one embodiment of the electrical connection assembly 220 shown in Figure 12. Figure 16 is a structural schematic diagram of the electrical connection assembly 220 shown in Figure 15 from another angle.

[0176] As shown in Figures 15 and 16, the electrical connection assembly 220 may include a circuit board 221, a flexible circuit board 222, and a metal terminal 223. The circuit board 221 includes a first surface 2211 and a second surface 2212 disposed opposite to each other. The metal terminal 223 is fixed to the first surface 2211 and electrically connected to the circuit board 221. One end of the flexible circuit board 222 is fixedly connected to the second surface 2212 of the circuit board 221 and is also electrically connected to the circuit board 221.

[0177] Understandably, when both ends of the watch strap 100 can be used for electrical connection to the watch body 200, the watch body 200 can include two electrical connection components 220. The flexible circuit boards 222 of the two electrical connection components 220 can be part of an integrally formed flexible circuit board. The flexible circuit boards 222 of the two electrical connection components 220 can share an interface for electrical connection with the electronic components 212 of the watch body 200, which can eliminate the need for an interface, simplify the structure, and make better use of the internal space of the watch body 200.

[0178] In other embodiments, the electrical connection component 220 may not include the flexible circuit board 222, but instead have signal lines electrically connected to the second side 2212 of the circuit board 221. It is understood that this application does not limit the specific structure of the electrical connection component 220.

[0179] Figure 17 is a partial cross-sectional view of one embodiment of the wearable device 1000 shown in Figure 1 at DD.

[0180] As shown in Figure 17, the circuit board 221 and the metal terminal 223 can be fixed within the first through hole 2103, with the metal terminal 223 fixedly connected to the surface of the circuit board 221 facing the external space. The metal terminal 223 protrudes relative to the outer casing 210. One end of the flexible circuit board 222 is fixedly connected to the circuit board 221 within the first through hole 2103, and the other end extends into the internal space of the outer casing 210 for electrical connection to the electronic device 212. It can be understood that component A protruding relative to component B means that component A can be directly seen when looking from the outer surface of component B into the internal space of component B.

[0181] In some embodiments, when the watch strap 100 is connected to the watch body 200, the elastic pin assembly 10 of the watch strap 100 can be electrically connected to the electrical connection assembly 220, thus achieving electrical conductivity between the watch strap 100 and the watch body 200. The first end 12 of the pin 1 of the elastic pin assembly 10 can abut against the metal terminal 223 of the electrical connection assembly 220, thus electrically connecting the metal terminal 223.

[0182] In some embodiments, the housing 210 further includes a bump 2110, which can be fixed to the wall of the first through hole 2103. The second surface 2212 of the circuit board 221 is fixedly connected to the side of the bump 2110 facing the external space of the housing 210, and the metal terminal 223 is fixedly connected to the surface of the circuit board 221 away from the bump 2110. Thus, when the circuit board 221 and the metal terminal 223 of the electrical connection assembly 220 are installed along the side surface 2107 of the housing 210 towards the internal space of the housing 210, the bump 2110 can serve as a positioning structure. When the second surface 2212 of the circuit board 221 contacts the bump 2110, the installation of the circuit board 221 and the metal terminal 223 is completed. The flexible circuit board 222 is installed from the internal space side of the housing 210, achieving a fixed connection and electrical connection with the second surface 2212 of the circuit board 221.

[0183] Understandably, in traditional technical solutions, the electrical connection component 220 is installed from the internal space of the housing 210 towards the external space. During the repeated disassembly and assembly of the watch strap 100 and the watch body 200, the pin 1 exerts a force against the metal terminal 223 from the external space towards the internal space, which can easily loosen the connection between the circuit board 221 and the housing 210, leading to unstable electrical connections. The bump 2110 is located on the outside of the circuit board 221, limiting the insertion depth of the pin 1 and reducing the space available for waterproofing, which is detrimental to the waterproofing between the watch strap 100 and the watch body 200. In this embodiment, the electrical connection assembly 220 is installed along the side 2107 of the outer casing 210 towards the internal space of the outer casing 210. On the one hand, the protrusion 2110 can be used as a positioning structure during the installation process, which is beneficial for quick installation. On the other hand, during the continuous disassembly and assembly of the watch strap 100 and the watch body 200, the pin 1 and the metal terminals 223 have a force abutting from the external space towards the internal space, making the connection between the circuit board 221 and the outer casing 210 less prone to loosening, and the electrical connection between the watch strap 100 and the watch body 200 has better reliability. In addition, a large space can be left in the first through hole 2103 for setting up a waterproof structure, which is beneficial to improving the electrical connection reliability between the watch strap 100 and the watch body 200.

[0184] For example, the second side 2212 of the circuit board 221 can be fixedly connected to the bump 2110 by double-sided adhesive.

[0185] In some embodiments, the protrusion 2110 may also be an integrally formed structural component with the housing 210. The connection strength between the protrusion 2110 and the housing 210 is better.

[0186] In some embodiments, the watch body 200 may further include a first waterproof component (not shown). The first waterproof component is fixedly connected to the second surface 2212 of the housing 210 and the circuit board 221, and covers the flexible circuit board 222 and the portion where the circuit board 221 is fixed. The first waterproof component may be cured with waterproof adhesive. The first waterproof component seals the gap between the circuit board 221 and the housing 210 to prevent moisture from the external space of the housing 210 from entering the interior of the watch body 200 through the gap between the circuit board 221 and the housing 210, thus preventing corrosion of the internal electronic components 212 of the watch body 200.

[0187] In some embodiments, the watch strap 100 may further include a second waterproof component (not shown). The second waterproof component is located within the watch strap body 20 and is fixedly connected to the end of the resilient pin assembly 10 furthest from the watch body 200. The second waterproof component seals the gap between the resilient pin assembly 10 and the watch strap body 20 to prevent moisture from the external space of the watch strap body 20 from entering the interior of the watch strap body 20 through the gap between the resilient pin assembly 10 and the watch strap body 20, thus preventing corrosion of the internal electronic components 21 of the watch strap body 20.

[0188] In some embodiments, when the watch strap 100 of this application is connected to the watch body 200, the elastic element 2 is compressed, giving the pin 1 a holding force toward the watch body 200, so that the first end 12 of the pin 1 abuts against and is electrically connected to the metal terminal 223. Exemplarily, the extension and retraction direction of the elastic element 2 and the movement direction of the pin 1 are the same as or at a slight angle to the insertion direction of the watch strap 100, for example, 2°, 3°, 5°, 7°, 10°, 15° or 20°.

[0189] Understandably, the traditional friction-type electrical connection in Type-C requires a relatively long insertion depth and a large insertion space, which is not conducive to the miniaturization of the device. The electrical connection between the watch band 100 and the watch body 200 in this application adopts a contact-type electrical connection, with the end of the pin 1 and the metal terminal 223 abutting along the insertion direction. This requires a smaller insertion depth, making it more suitable for small-sized wearable devices 1000, or conducive to the miniaturization of wearable devices 1000.

[0190] In some embodiments, when the watch strap 100 is not connected to the watch body 200, the first end 12 of the pin 1 protrudes from the housing 4 by a first protrusion height H1 (as shown in Figure 4). When the watch strap 100 is connected to the watch body 200, the first end 12 of the pin 1 protrudes from the housing 4 by a second protrusion height H2 (as shown in Figure 17). The second protrusion height H2 is less than the first protrusion height H1. When the watch strap 100 is connected to the watch body 200, the pin 1 moves relative to the housing 4 and abuts against the metal terminal 223.

[0191] In some embodiments, the surface of the metal terminal 223 facing the ejector pin 1 may have a groove (not shown). The groove surface can be designed according to the surface of the first end 12 of the ejector pin 1, so that when the first end 12 of the ejector pin 1 abuts against the metal terminal 223, the first end 12 of the ejector pin 1 abuts against the groove surface. For example, the groove surface can be designed as an arc surface. It is understood that, compared to a scheme where the surface of the metal terminal 223 facing the ejector pin 1 is flat, providing a groove increases the contact area between the metal terminal 223 and the ejector pin 1, which helps to reduce resistance and improve the stability of the electrical connection.

[0192] In some embodiments, the watch body 200 may also be provided with a clamping spring (not shown). The clamping spring is installed in the first through hole 2103, and when the watch strap 100 is connected to the watch body 200, the clamping spring can abut against the side 2107 of the pin 1.

[0193] In other embodiments, the wire 3 can be fixedly connected to the end of the elastic element 2 away from the pin 1, and the electrical signal of the pin 1 is transmitted out of the housing 4 through the elastic element 2 and the wire 3. In this way, compared with the solution where the wire 3 is fixedly connected to the pin 1, the wire 3 is fixedly connected to the end of the elastic element 2 away from the pin 1, and the length of the wire 3 inside the housing 4 is shorter. This avoids interference between the wire 3 and the elastic element 2 when the user shakes the wearable device 1000, which would cause the elastic element 2 to become stuck, preventing the pin 1 from moving relative to the housing 4, or making its movement inflexible.

[0194] In some embodiments, when the watch strap 100 is connected to the watch body 200, the waterproof ring 8 of the elastic pin assembly 10 abuts against the metal housing 7 and the housing 210. Exemplarily, the waterproof ring 8 may abut against the wall surface of the metal housing 7 and the first through hole 2103. It is understood that by setting the size of the waterproof ring 8 and the gap between the metal housing 7 and the first through hole 2103, the waterproof ring 8 can be interference-fitted into the gap between the metal housing 7 and the first through hole 2103 to prevent moisture from the external space of the watch body 200 from entering the position of the pin 1 and the metal terminal 223 through the gap between the metal housing 7 and the first through hole 2103, thereby ensuring the reliability of the electrical connection between the metal terminal 223 and the pin 1.

[0195] For example, the waterproof ring 8 can be made of an elastic insulating material such as rubber.

[0196] Figure 18 is a structural schematic diagram of one embodiment of the holding assembly 230 shown in Figure 12. Figure 19 is a cross-sectional schematic diagram of one embodiment of the wearable device 1000 shown in Figure 1 at EE. Figure 20 is a partial cross-sectional schematic diagram of one embodiment of the wearable device 1000 shown in Figure 1 at FF.

[0197] As shown in Figures 18 to 20, the retaining assembly 230 may include a spring 231, a retaining pin 232, and a retaining member 233. When the retaining assembly 230 is installed on the housing 210, it can be engaged in the retaining groove 2104. When the watch strap 100 is detachably connected to the watch body 200, the retaining assembly 230 engages with the watch strap 100 to secure the watch strap 100 and the watch body 200.

[0198] In some embodiments, the retaining member 233 may include an abutment portion 2331, a first retaining portion 2332, and a second retaining portion 2333. The first retaining portion 2332 is fixedly connected to the second retaining portion 2333. The abutment portion 2331 is fixedly connected to the first retaining portion 2332. The first retaining portion 2332 is provided with a sliding groove 2335. The second retaining portion 2333 is provided with a first inclined surface 2334. When the retaining assembly 230 is installed on the housing 210, the elastic member 2 abuts against the abutment portion 2331 of the retaining member 233 and the housing 210. The retaining bolt 232 is slidably connected to the sliding groove 2335.

[0199] In some embodiments, the retaining component 230 is engaged within the retaining groove 2104. Exemplarily, the spring 231 is located within the retaining groove 2104 and abuts against the abutting portion 2331 of the retaining member 233 and the wall of the retaining groove 2104. The housing 210 may have a fixing hole 2100, which connects the side surface 2107 of the housing 210 and the retaining groove 2104. The fixing bolt 232 is fixedly connected to the fixing hole 2100, partially located within the retaining groove 2104, and slidably connected within the sliding groove 2335 of the first retaining portion 2332. Understandably, the spring 231 abuts against the wall of the abutment part 2331 and the locking groove 2104, and the retaining member 233 is subjected to the abutment force, which tends to move outward toward the locking groove 2104. The fixing bolt 232 can fix the outer shell 210 and is locked in the sliding groove 2335 to prevent the retaining member 233 from falling out of the locking groove 2104 due to the action of the spring 231.

[0200] In some embodiments, the number of springs 231 and fixing bolts 232 can be two, and the number of abutment portions 2331 and first locking portions 2332 can also be two. Two springs 231 and two abutment portions 2331 can be connected in a one-to-one correspondence. Two fixing bolts 232 and two first locking portions 2332 can also be connected in a one-to-one correspondence. One spring 231 and one fixing bolt 232 form a group, with two groups located on opposite sides of the first through hole 2103. This facilitates force balance on the retaining member 233.

[0201] In some embodiments, the retaining member 233 may further include a connecting portion 2336, which is fixedly connected between the two first engaging portions 2332. In this way, the two first engaging portions 2332 of the retaining member 233 can be integrated as a whole, which facilitates user operation.

[0202] Figure 21 is a partial cross-sectional view of one embodiment of the wearable device 1000 shown in Figure 1 at GG.

[0203] As shown in Figures 19 to 21, when the watch strap 100 is detachably connected to the watch body 200, the hook 2022 of the watch strap 100 can enter the locking groove 2104 through the second through hole 2106 and engage with the second locking part 2333. The watch strap 100 can achieve a fixed connection with the watch body 200. For example, the hook 2022 of the watch strap 100 may be provided with a second inclined surface 2023. When the hook 2022 enters the locking groove 2104 through the second through hole 2106, the second inclined surface 2023 can abut against the first inclined surface 2334. Through the cooperation of the first inclined surface 2334 and the second inclined surface 2023, the retaining member 233 can move upwards, compressing the spring 231. After the hook 2022 enters the locking groove 2104, the retaining member returns to its original position under the action of the spring 231, engaging the hook 2022. The second holding part is located on the side of the hook 2022 facing the external space of the housing 210.

[0204] Understandably, when a user needs to remove the watch strap 100 from the watch body 200, they can press the latching member at the opening of the latching slot 2104. The latching member moves upward under force, compressing the spring 231, and the second holding part and the latch hook 2022 disengage. The user can then remove the latch hook 2022 from the latching slot 2104 to remove the watch strap 100.

[0205] For example, when the watch strap 100 is connected to the watch body 200, the buffer 203 (as shown in FIG. 1) can abut between the watch strap 100 and the outer casing 210 of the watch body 200. It is understood that the buffer 203 can be used to absorb gaps in the engagement between the latch 2022 and the watch body 200, reducing movement between the watch strap 100 and the watch body 200. For example, the buffer 203 can be software. In other embodiments, the buffer 203 can also be disposed on the watch body 200.

[0206] In some embodiments, the housing 210 may further include a support platform 2108, which may be disposed within the snap-fit ​​groove 2104. The support platform 2108 may be used to support the snap hook 2022. For example, when the watch strap 100 is mounted on the watch body 200, along the thickness direction of the watch body 200, the head of the snap hook 2022 may be positioned opposite to the support platform 2108, and the tail of the snap hook 2022 may be positioned opposite to the wall surface of the second through hole 2106. The retaining member 233 engages with the middle portion of the snap hook 2022. In this way, the snap hook 2022 is subjected to balanced forces, which helps to reduce the risk of the snap hook 2022 wobbling within the snap-fit ​​groove 2104.

[0207] Figure 22 is a structural schematic diagram of another embodiment of the wearable device 1000 provided in this application. Figure 23 is an exploded schematic diagram of an embodiment of the wearable device 1000 shown in Figure 22.

[0208] As shown in Figures 22 and 23, the wearable device 1000 may include a watch body 200 and two watch straps 100. The two watch straps 100 are respectively connected to both ends of the watch body 200. In this embodiment, the watch straps 100 are made of a soft material, such as rubber. This provides a better user experience when using the wearable device 1000.

[0209] In other embodiments, the wearable device 1000 may include a watch strap 100, a watch body 200, and an auxiliary watch strap. An auxiliary watch strap refers to a watch strap that does not contain electronic components and is only used to secure the watch body 200. That is, when the wearable device 1000 has two watch straps, the electronic component 21 may be located on only one of the watch straps.

[0210] It is understandable that the two watch straps 100 shown in Figures 22 and 23 can have electronic components installed in one or both of them, depending on the specific design requirements.

[0211] Figure 24 is an exploded view of one embodiment of the watch strap 100 shown in Figure 23.

[0212] As shown in Figure 24, the watch strap 100 may include a watch strap body 20 and a flexible pin assembly 10. The flexible pin assembly 10 may be fixed to one end of the watch strap body 20 for electrical connection between the watch strap 100 and the watch body 200.

[0213] Figure 25 is an exploded view of one embodiment of the watchband body 20 shown in Figure 24. Figure 26 is a structural schematic diagram of one embodiment of the elastic pin assembly 10 and the frame 120. Figure 27 is a partially exploded structural schematic diagram of one embodiment of the watchband 100 shown in Figure 23.

[0214] As shown in Figures 24 to 27, the watch strap body 20 may include a soft rubber strap 110 and a frame 120. Electronic components 21 are disposed inside the soft rubber strap 110. The frame 120 is embedded in the soft rubber strap 110 and partially exposed. It is understood that the frame 120 is made of metal and can have good strength. The frame 120 can be used to mount the elastic pin assembly 10. Exemplarily, the elastic pin assembly 10 can be fixedly connected to the frame 120 by screws 130. Exemplarily, the frame 120 can be made of metal or a polymer material, thereby achieving high strength for mounting the elastic pin assembly 10. This application does not limit the material of the frame 120. For example, the frame 120 can be made of metal, which has high hardness, resulting in a frame 120 with high strength.

[0215] In some embodiments, the frame 120 has a hook 2022. When the frame 120 is embedded in the soft rubber strap 110, the hook 2022 protrudes from one end of the soft rubber strap 110 and is used for connection between the strap 100 and the watch body 200.

[0216] For example, the soft rubber watch strap 110 may include a body 111 and a diaphragm 112. The diaphragm 112 is fixedly connected to the body 111 to protect the electronic components 21 inside the soft rubber watch strap 110.

[0217] As shown in Figure 27, when the watch strap 100 is a soft strap, the electronic device 21 can be flexible, and / or, the electronic device 21 can be a thin sheet structure. In this way, when the user wears the device 1000, the watch strap 100 bends, and the electronic device 21 can cooperate with the bending curvature of the watch strap 100 to avoid damage to the electronic device 21.

[0218] It is understood that when the electronic device 21 is small in size, it may also be block-shaped or lack flexibility. This application does not limit the type of device within the soft rubber strap 110; those skilled in the art can selectively configure it according to their needs.

[0219] Figure 27 illustrates that electronic device 21 is a solar panel. The solar panel can convert solar energy into electrical energy. It is understood that when electronic device 21 is a solar panel, camera, or other device requiring external light, the soft rubber strap 110 can be designed to be transparent as needed to meet the light requirements of electronic device 21. It is also understood that in the embodiments shown in Figures 1 to 21 of this document, when electronic device 21 is a solar panel, camera, or other device requiring external light, the strap 100 can also be made transparent according to the light requirements.

[0220] In some embodiments, the interior of the soft rubber strap 110 may be potted with adhesive to protect and waterproof the electronic components 21.

[0221] In some embodiments, the watchband body 20 may further include a signal transmission structure 205. The signal transmission structure 205 can be disposed inside the watchband body 20 for electrical signal transmission between electronic devices 21 inside the two watchband bodies 20, or for electrical signal transmission between the elastic pin assembly 10 and the electronic devices 21 inside the watchband body 20. The signal transmission structure 205 in this embodiment can be set with reference to the signal transmission structure 205 in the previous embodiments, or can be adaptively adjusted according to the specific structure of the watchband body 20; this application does not impose any limitations. For example, when the watchband 100 is a soft watchband, the signal transmission structure 205 can be set to have a flexible, bendable structure to accommodate deformation within the soft rubber watchband 110.

[0222] Figure 28 is a partial structural schematic diagram of another embodiment of the watch strap 100 shown in Figure 23.

[0223] As shown in Figures 23 and 28, the electronic device 21 can also be a flexible battery. It is understood that by configuring the battery as a flexible sheet-like structure, the battery gains deformability, making it suitable for scenarios where the watchband 100 needs to be bent, thus avoiding damage to the device.

[0224] It is understandable that the electronic device 21 shown in Figure 28 is roughly racetrack-shaped, with rounded ends. The electronic device 21 can be placed in a long watchband 100 with rounded ends, which is a better fit and provides more space along the length of the watchband 100 to accommodate the electronic device 21.

[0225] In other embodiments, the wearable device 1000 may include a watch strap 100 and a watch body. The watch strap 100 is detachably connected to the watch body. The watch body may be a watch body without electrical connection components. The watch body may achieve electrical connection with the watch strap 100 in other ways. When the watch strap 100 is connected to the watch body, the pin 1 is electrically connected to the watch body.

[0226] In other embodiments, the wearable device 1000 may include a watch strap and a watch body 200. The watch strap is detachably connected to the watch body 200. The watch strap may be a watch strap without the elastic pin assembly 10. The watch strap may achieve electrical connection with the watch body 200 in other ways. When the watch strap is connected to the watch body 200, the watch strap is electrically connected to the metal terminal 223.

[0227] It is understood that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0228] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0229] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
