Description

Watch straps, wearable devices, and elastic connectors

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on January 3, 2024, with application number: 202410008206.2, and priority to the Chinese patent application with the invention name “Watch strap, wearable device and elastic connector”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of wearable devices, and in particular to a watch strap, a wearable device, and an elastic connector. Background Art

[0003] In smart watches, the strap and the watch body are detachably connected. The strap needs to be replaced many times, and the strap and the watch body need to be disassembled many times. The connection structure between the strap and the watch body is subject to wear and other problems, resulting in poor connection reliability between the watch body and the strap. Summary of the Invention

[0004] The present application provides a watch strap, a wearable device, and an elastic connector.

[0005] In a first aspect, embodiments of the present application provide a watch strap. The watch strap includes a rigid thimble assembly and a watch strap body. The rigid thimble assembly includes a rigid thimble, a fixing member, and a first housing. The first housing is fixedly connected to the watch strap body. The fixing member is fixed between the rigid thimble and the first housing. The rigid thimble is an integral structural member used to transmit electrical signals.

[0006] It's understandable that, compared to solutions using elastic ejector pins for transmitting electrical signals, the rigid ejector pins of this application don't experience compression deformation, don't suffer from jamming issues, and offer improved electrical connection reliability. Furthermore, the rigid ejector pins have a simple structure, require no post-assembly steps, and are easy to manufacture, resulting in a low-cost solution.

[0007] In one possible embodiment, the first housing has a first end face and a second end face disposed in opposite directions, with the second end face connected to the watchband body. The first housing has a first through-hole extending through the first and second end faces. A rigid ejector pin is embedded in a fixing member secured within the first through-hole. One end of the rigid ejector pin extends through the first end face, while the other end is exposed through the second end face. In this manner, the first housing can protect the rigid ejector pin within the first through-hole.

[0008] In one possible embodiment, the rigid ejector pin assembly further includes a waterproof member disposed within the first through-hole, on the side of the fixing member proximal to the first end face. The waterproof member is positioned between the rigid ejector pin and the wall of the first through-hole. This prevents external moisture from entering the watchband body through the gaps between the rigid ejector pin, the first housing, and the fixing member.

[0009] In one possible embodiment, there are multiple rigid pins, and the multiple rigid pins are arranged at intervals along the width direction of the strap body. The length direction of the rigid pins is the same as the length direction of the first shell, and the length direction of the first shell is the direction from the first end face to the second end face.

[0010] It can be understood that compared with the solution of arranging multiple rigid thimbles at intervals along the thickness direction of the strap body, multiple rigid thimbles can be arranged at intervals along the width direction of the strap body. More rigid thimbles can be arranged without increasing the thickness of the strap body, which is conducive to the slimming of the strap.

[0011] In one possible embodiment, the first shell is embedded in the watch band body, and one end of the first shell extends out of the watch band body. In this way, when the watch band is connected to the watch body, the extended portion of the first shell can be fixed to the watch body by plugging.

[0012] In one possible embodiment, the rigid ejector pin is in the shape of an elongated strip. In this way, the rigid ejector pin is smaller in size, and more rigid ejector pins can be used in a limited space to achieve multi-channel electrical signal transmission.

[0013] In a second aspect, embodiments of the present application provide a wearable device comprising a watch body and a watch strap, the watch strap being detachably connected to the watch body. The watch body comprises a watch body and an elastic connecting assembly, the elastic connecting assembly being disposed on the watch body and configured to electrically connect a rigid ejector pin and to be fixedly connected to a first housing. The elastic connecting assembly includes at least one elastic conductor. When the watch strap is connected to the watch body, the rigid ejector pin abuts against the elastic conductor, causing the elastic conductor to deform and establish electrical continuity between the elastic conductor and the rigid ejector pin.

[0014] It can be understood that when the watch strap is connected to the watch body, compared with the elastic ejector pin solution, the rigid ejector pin used in this application does not have the problem of jamming, and the electrical reliability between the watch strap and the watch body is better.

[0015] In a possible implementation, the elastic conductor includes a conductive part and an elastic insulating part, the elastic insulating part is connected to the conductive part, and when the watch strap is connected to the watch body, the elastic insulating part is compressed and the rigid ejector pin is electrically connected to the conductive part.

[0016] It is understandable that when the watch strap is connected to the watch body, the elastic insulating part may be deformed. The elastic insulating part can provide a certain buffer stroke to avoid the generation of large force between the rigid thimble and the conductive part, which may cause damage to the rigid thimble or the conductive part.

[0017] In a possible implementation, there are multiple conductive members, and the elastic insulating member is located between adjacent conductive members.

[0018] It can be understood that when the watch strap is connected to the watch body, the elastic insulating part is compressed, the distance between adjacent conductive parts is reduced, multiple conductive parts can form an electrically conductive path, and the rigid ejector pin can electrically connect the conductive parts. It should be noted that when the elastic insulating part is compressed, the distance between adjacent conductive parts is reduced, which means that the distance between at least two adjacent conductive parts is reduced, and it is not necessary for the distance between all adjacent conductive parts to be reduced. The elastic insulating part is compressed, and the distance between some adjacent conductive parts among the multiple conductive parts can be reduced, forming an electrically conductive path, which can be used to transmit electrical signals. The more conductive parts there are, the less the elastic insulating part is compressed, and the less it is affected by the direction of the holding force of the rigid ejector pin, and it is easier to form an electrically conductive path between multiple conductive parts, and the electrical connection reliability of the elastic conductor is higher.

[0019] When the watch strap and watch body are detached, the elastic insulating member returns to its original shape, increasing the distance between the conductive members and preventing them from forming an electrical path. When the strap and watch body are disconnected, the elastic conductive members are de-energized, reducing the risk of corrosion.

[0020] In a possible implementation, the conductive member is a spherical particle, and / or the elastic insulating member is made of silicone or plastic.

[0021] It's understood that spherical particles are isotropic. In other words, they exhibit the same properties in every direction. For example, electrical properties like impedance and withstand voltage are common. When spherical particles are used as conductive elements, the elastic conductor exhibits better electrical properties in all directions. Elastic insulating elements made of silicone or plastic offer excellent insulation and elasticity.

[0022] In one possible implementation, when the watch strap is disconnected from the watch body, the length of the elastic insulating member along a first direction is L1. When the watch strap is connected to the watch body, the minimum length of the elastic insulating member along the first direction is L2. The first direction is the direction in which the rigid ejector pin faces the conductive member when the watch strap is connected to the watch body. The difference between L1 and L2 is in the range of 0.1 mm to 1 mm.

[0023] It is understandable that when the watch strap is connected to the watch body, the elastic insulating part can achieve electrical conduction between the conductive part and the rigid thimble with a small degree of deformation. The watch body does not need to reserve a large deformation space, which is conducive to reducing the volume of the watch body.

[0024] In a possible embodiment, the first shell is provided with a groove, the opening of the groove is located on the peripheral side of the first shell, and the elastic connection component further includes a clamping component. When the watch strap is connected to the watch body, part of the clamping component is held in the groove.

[0025] It is understood that the clamping assembly can be used to secure the watch strap. The groove can serve as a positioning function. When the watch strap is installed on the watch body, when the clamping member enters the groove, it can abut the first housing along the installation direction of the watch strap. At this time, the user can clearly feel the resistance increase. In this way, the user can judge whether the watch strap is installed properly based on the resistance encountered when inserting the watch strap.

[0026] In one possible embodiment, the elastic connection assembly further includes a button assembly, which is movably connected to the watch body, and the button assembly and the first shell are spaced apart. When the button assembly moves in the second direction, the button assembly abuts against the holding assembly, and the holding assembly withdraws from the groove.

[0027] It is understood that the button assembly can be used to disassemble the watch strap from the watch body. When the user needs to disassemble the watch strap, the button assembly can be pressed, so that when the button assembly moves in the second direction, the clamping assembly exits the groove, thereby achieving quick disassembly of the watch strap and the watch body.

[0028] In a possible embodiment, there are multiple holding components, and the number of grooves is equal to the number of holding components. When the watch strap is connected to the watch body, the multiple holding components are respectively arranged on both sides of the first shell and are arranged one-to-one corresponding to the grooves.

[0029] It is understandable that by arranging multiple clamping components on both sides of the first shell, force can be applied from both sides to fix the first shell, reducing the risk of shaking of the first shell, thereby improving the connection reliability between the watch strap and the watch body.

[0030] In a third aspect, embodiments of the present application provide an elastic connector. The elastic connector includes a rigid ejector pin and an elastic conductor. The rigid ejector pin is detachably connected to the elastic conductor. When the rigid ejector pin is connected to the elastic conductor, the rigid ejector pin abuts against the elastic conductor, causing the elastic conductor to deform and establish electrical conduction between the elastic conductor and the rigid ejector pin. When the elastic connector is used to transmit electrical signals between two detachably connected components, the rigid ejector pin can be installed on one component, and the elastic conductor can be installed on the other component.

[0031] It's understandable that, compared to elastic pins used in flexible connectors to achieve electrical conductivity, rigid pins don't experience compression deformation and won't cause jamming due to misdirected force. In other words, rigid pins don't experience jamming, and the electrical connection between them and the elastic conductor is more reliable. Furthermore, rigid pins have a simple structure, requiring no post-assembly steps, making their production process simple and cost-effective.

[0032] In a possible implementation, the elastic conductor includes a conductive part and an elastic insulating part, the elastic insulating part is connected to the conductive part, and when the watch strap is connected to the watch body, the elastic insulating part is compressed and the rigid ejector pin is electrically connected to the conductive part.

[0033] It is understandable that when the rigid ejector pin is connected to the elastic conductor, the elastic insulating part may deform. The elastic insulating part can provide a certain buffer stroke to avoid the generation of large forces between the rigid ejector pin and the conductive part, which may cause damage to the rigid ejector pin or the conductive part.

[0034] In a possible implementation, there are multiple conductive members, and the elastic insulating member is located between adjacent conductive members.

[0035] It can be understood that when the rigid ejector pin is connected to the elastic conductor, the elastic insulating member is compressed, the distance between adjacent conductive members is reduced, and multiple conductive members can form an electrically conductive path, and the rigid ejector pin can electrically connect the conductive members. It should be noted that when the elastic insulating member is compressed, the reduction in the distance between adjacent conductive members refers to the reduction in the distance between at least two adjacent conductive members, and it is not necessary for the distance between all adjacent conductive members to be reduced. The elastic insulating member is compressed, and the distance between some adjacent conductive members among the multiple conductive members can be reduced, forming an electrically conductive path, which can be used to transmit electrical signals. The more conductive members there are, the less the elastic insulating member is compressed, and the less it is affected by the direction of the holding force of the rigid ejector pin, and it is easier to form an electrically conductive path between multiple conductive members, and the electrical connection reliability of the elastic conductor is higher.

[0036] In a possible implementation, the conductive member is a spherical particle, and / or the elastic insulating member is made of silicone or plastic.

[0037] It's understood that spherical particles are isotropic. In other words, they exhibit the same properties in every direction. For example, electrical properties like impedance and withstand voltage are common. When spherical particles are used as conductive elements, the elastic conductor exhibits better electrical properties in all directions. Elastic insulating elements made of silicone or plastic offer excellent insulation and elasticity.

[0038] In one possible embodiment, when the rigid ejector pin is disconnected from the elastic conductor, the length of the elastic insulating member along a first direction is L1. When the rigid ejector pin is connected to the elastic conductor, the minimum length of the elastic insulating member along the first direction is L2. The first direction is the direction in which the rigid ejector pin faces the conductive member when the rigid ejector pin is connected to the elastic conductor. The difference between L1 and L2 is in the range of 0.1 mm to 1 mm.

[0039] It is understandable that electrical conduction between the conductive member and the rigid ejector pin can be achieved with a relatively small degree of deformation of the elastic insulating member, which is beneficial for reducing the volume of the elastic connector.

[0056] The embodiments of the present invention are described below in conjunction with the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0057] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. 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 the present application, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A is connected to B or A and B are connected to each other, which means that there is a fastening component (such as a screw, bolt, rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0058] Furthermore, the term "fixed" as used herein should be broadly construed. For example, "fixed" can mean directly fixed or indirectly fixed through an intermediary. "Fixed connection" refers to a connection in which the relative positional relationship remains unchanged. "Rotationally connected" refers to a connection in which the connection allows relative rotation. "Slidingly connected" refers to a connection in which the connection allows relative sliding.

[0059] The directional terms mentioned in the embodiments of this application, such as "upper" and "lower", are only used to refer to the directions in the accompanying drawings. Therefore, the directional terms used are intended to better and more clearly illustrate and understand the embodiments of this application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of this application. "Multiple" means two or more than two.

[0060] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0061] In the embodiments of this application, the term "plurality" refers to two or more than two. Furthermore, the term "and / or" simply describes an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0062] It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0063] In smart watches, in order to facilitate the replacement of watch straps, the watch strap and the watch body are designed to be detachably connected. An elastic pin is provided on the watch strap to achieve electrical connection between the electronic devices on the watch strap and the watch body. The elastic pin includes a spring, a needle and a needle tube, and the needle tube is electrically connected to the electronic devices on the watch strap. A metal patch is provided on the watch body side, one end of the needle is electrically connected to the metal patch, and the other end is used to electrically connect to the base. The needle is partially located in the needle tube, and the needle is moved in the needle tube by a spring. When the watch strap is installed on the watch body, the spring is in a compressed state, and one end of the needle moves toward the bottom of the needle tube, electrically connecting to the needle tube. When the watch strap is removed from the watch body, the spring is in an extended state, and the needle moves to the side away from the needle tube, disconnecting the electrical connection between the needle tube. There are several problems with using an elastic pin to achieve electrical connection between the watch strap and the watch body: (1) The needle and the needle tube are rubbed multiple times or the preparation accuracy is low, which causes the needle and the needle tube to easily get stuck, resulting in poor reliability of the electrical connection between the watch strap and the watch body. (2) The needle or metal patch is easily corroded by sweat, resulting in poor electrical connection reliability between the strap and the watch body. (3) The high cost of spring-loaded thimbles leads to high costs for strap replacement.

[0064] Fig. 1 is a schematic diagram of the structure of an embodiment of a wearable device 1000 provided by the present application. Fig. 2 is an exploded schematic diagram of an embodiment of the wearable device 1000 shown in Fig. 1 .

[0065] The wearable device 1000 can be a watch or a bracelet. The wearable device 1000 shown in FIG1 is described using a watch as an example. It should be noted that FIG1 and FIG2 only schematically illustrate some components included in the wearable device 1000, and the actual size, actual position, and actual structure of these components are not limited by the figures. The following figures also only schematically illustrate some components, and the actual size, actual position, and actual structure of these components are not limited by the following figures. The details will not be repeated below.

[0066] As shown in Figures 1 and 2, a 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. For example, there may be two watch straps 100, one connected to each end of the watch body 200. When a user wears the wearable device 1000, the watch strap 100 may be used to secure the watch body 200 to the user. In other embodiments, there may be only one watch strap 100.

[0067] The watchband 100 can be detachably connected to the watch body 200. This allows the watchband 100 to be replaced when it becomes dirty or damaged, without having to replace the entire wearable device 1000. The following describes an embodiment of the detachable connection between the watchband 100 and the watch body 200 in detail, with reference to the accompanying drawings.

[0068] The strap 100 may include a first electronic device 21. The watch body 200 may include a second electronic device 212. (The first electronic device 21 and the second electronic device 212 are schematically illustrated by dotted boxes in FIG2 ) Exemplarily, the first electronic device 21 may include one or more of an electrocardiogram detection electrode, a sensor, an antenna, a processor, an internal memory, a battery, a communication module, a camera, an audio module, a speaker, a microphone, a motor, and an indicator. The second electronic device 212 may include one or more of an electrocardiogram detection electrode, a sensor, an antenna, a processor, an internal memory, a battery, 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 quantities of the first electronic device 21 and the second electronic device 212 may be the same or different.

[0069] It can be understood that compared with the solution of integrating all electronic components on the watch body 200, the present application sets part of the electronic components of the wearable device 1000 on the strap 100 and part of the electronic components on the watch body 200, which can reduce the volume of the watch body 200 and is conducive to the miniaturization of the wearable device 1000.

[0070] In some embodiments, the first electronic device 21 may include a first ECG detection electrode, which may be provided on the inner side of the strap body 20. The second electronic device 212 may include a second ECG detection electrode, which may be provided on the inner side of the second shell 211. The inner side of the second shell 211 is the side surface close to the user's skin when the user wears the watch. The inner side of the strap body 20 is the side surface close to the user's skin when the user wears the watch. It can be understood that compared to the solution of only providing ECG detection electrodes on the watch body 200, the present application provides the first ECG detection electrode and the second ECG detection electrode on the watch body 200 and the strap 100 respectively. When the user wears the wearable device, ECG can be detected at multiple points, thereby improving the accuracy of ECG detection.

[0071] When some of the electronic components of the wearable device 1000 are located on the strap 100 and some are located on the watch body 200, the wearable device 1000 can be provided with an electrical connection structure for transmitting electrical signals between the first electronic component 21 of the strap 100 and the second electronic component 212 of the watch body 200. Taking ECG detection as an example, when the first ECG detection electrode is in operation and both the battery and the processor are located on the watch body 200, the battery is required to provide power while also transmitting the detected signal to the processor. The processor then analyzes the signal from the first and second ECG detection electrodes to obtain the user's ECG information.

[0072] Several implementation methods for achieving electrical connection between the watch strap 100 and the watch body 200 will be described below with reference to the accompanying drawings.

[0073] FIG. 3 is an exploded schematic diagram of an embodiment of the watch strap 100 shown in FIG. 2 .

[0074] As shown in Figures 2 and 3, the watchband 100 may also include a rigid ejector pin assembly 10 and a watchband body 20. The rigid ejector pin assembly 10 is disposed on the watchband body 20. The rigid ejector pin 1 is made of a conductive material and can be used to transmit electrical signals. The watchband body 20 may include a first electronic device 21. The rigid ejector pin assembly 10 can be used to transmit electrical signals between the first electronic device 21 and the watch body 200.

[0075] Figure 4 is a schematic structural diagram of an embodiment of the rigid ejector pin assembly 10 shown in Figure 3. Figure 5 is an exploded schematic diagram of an embodiment of the rigid ejector pin assembly 10 shown in Figure 4. Figure 6 is a cross-sectional view of an embodiment of the rigid ejector pin assembly 10 shown in Figure 4 taken along section line AA.

[0076] As shown in Figures 4 to 6, the rigid ejector pin assembly 10 may include a rigid ejector pin 1, a fixing member 2 and a first shell 3. The fixing member 2 is fixed between the rigid ejector pin 1 and the first shell 3. The rigid ejector pin 1 is an integral structural member for transmitting electrical signals. It should be noted that the rigid ejector pin 1 of the present application is relative to the elastic ejector pin described above, and the rigid ejector pin 1 is not easily deformed when subjected to external force. The rigid ejector pin 1 being an integral structural member means that the rigid ejector pin 1 can be formed after a one-time preparation process, eliminating the parts assembly process.

[0077] It is understandable that, compared to the solution of providing an elastic ejector pin for electrical signal transmission, the rigid ejector pin 1 of the present application does not undergo compression deformation and will not cause jamming due to incorrect force direction. In other words, the rigid ejector pin 1 does not have the jamming problem and has better reliability. In addition, the rigid ejector pin of the present application is an integrated structural component that does not require the coordination of parts, thus avoiding jamming problems caused by large friction between parts. Moreover, the rigid ejector pin 1 has a simple structure and does not require a subsequent assembly process. The preparation process is simple and the preparation cost is low. When the watch strap 100 needs to be replaced, the replacement cost is low.

[0078] In some embodiments, the rigid ejector pin 1 can be manufactured by a turning process or a stamping process. It is understood that the manufacturing process of the rigid ejector pin 1 is simple and has a high manufacturing yield.

[0079] In some embodiments, the rigid ejector pin 1 can be made of metal materials such as copper and copper alloys. In this way, the rigid ejector pin 1 has good conductivity and strength, and the raw materials are easy to obtain and low in cost.

[0080] In some embodiments, the first shell 3 may include a first end face 31, a second end face 32, and a circumferential side face 33 connected between the first end face 31 and the second end face 32. The first end face 31 and the second end face 32 are arranged in a back-to-back relationship. The first shell 3 may be provided with a first through hole 34. The first through hole 34 may pass through the first end face 31 and the second end face 32. The rigid ejector pin 1 may be embedded in the fixing member 2, and the fixing member 2 may be fixed in the first through hole 34, with one end of the rigid ejector pin 1 extending from the first end face 31 and the other end exposed from the second end face 32. In this way, the first shell 3 can be used to protect the rigid ejector pin 1 located in the first through hole 34.

[0081] In some embodiments, the first housing 3 can be made of a stronger material, such as stainless steel. This prevents the first housing 3 from deforming during repeated disassembly of the watch band 100 and the watch body 200, thereby better protecting the rigid ejector pin 1 located in the first through hole 34.

[0082] In some embodiments, the first housing 3 may be provided with a groove 35. The opening of the groove 35 may be located on the peripheral side 33 of the first housing 3. For example, there may be two grooves 35, which may be located on both sides of the first through hole 34, respectively.

[0083] The fixing member 2 can be used to fix the rigid ejector pin 1 on the first housing 3 to prevent the rigid ejector pin 1 from shaking due to inertia or external force during use.

[0084] The number of rigid ejector pins 1 can be one or more. In some embodiments, the number of rigid ejector pins 1 is multiple. Multiple rigid ejector pin assemblies 10 can transmit different electrical signals respectively.

[0085] In some embodiments, multiple rigid thimbles 1 can be spaced apart along the width of the watchband body 20. The length of the rigid thimbles 1 is the same as the length of the first shell 3. The length of the first shell 3 is the direction from the first end surface 31 to the second end surface 32. Thus, compared to a solution in which multiple rigid thimbles 1 are spaced apart along the thickness of the watchband body 20, multiple rigid thimbles 1 can be spaced apart along the width of the watchband body 20. This allows for a greater number of rigid thimbles 1 to be provided without increasing the thickness of the watchband body 20, thereby facilitating a slimmer watchband 100.

[0086] In some embodiments, the rigid ejector pin 1 may be a solid long strip structure. In this way, the rigid ejector pin 1 is smaller in size, and more rigid ejector pins 1 can be used in a limited space to achieve multi-channel electrical signal transmission.

[0087] The fixing member 2 can be made of an insulating material, for example, a rubber material. The fixing member 2 can also be used to insulate the rigid ejector pins 1, including insulation between the rigid ejector pins 1 and the first housing 3 and / or between two adjacent rigid ejector pins 1. The fixing member 2 can be positioned between the rigid ejector pins 1 and the first housing 3. If there are multiple rigid ejector pins 1, the fixing member 2 can also be positioned between adjacent rigid ejector pins 1.

[0088] In some embodiments, the rigid ejector pin 1 and the fixing member 2 can be formed into an integrated structure through an integrated molding process. The rigid ejector pin 1 can be non-detachably connected to the fixing member 2, and the connection strength is good. Among them, the two components are integrated into a structure through an integrated molding process, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together through further processing (such as bonding, welding, snap connection, screw connection). For example, the rigid ejector pin 1 and the fixing member 2 can be formed into an integrated structure through an injection molding process.

[0089] In other embodiments, the rigid ejector pin 1 and the fixing member 2 may be prepared separately, and then assembled with the rigid ejector pin 1 and the fixing member 2 by bonding, welding, etc. The rigid ejector pin 1 is detachably connected to the fixing member 2 .

[0090] In some embodiments, the rigid ejector pin assembly 10 may further include a waterproof member 4. For example, the waterproof member 4 may be disposed within the first through-hole 34, on the side of the fixing member 2 near the first end surface 31. The waterproof member 4 is positioned between the rigid ejector pin 1 and the wall of the first through-hole 34. The waterproof member 4 prevents external moisture from entering the watchband body 20 through the gap between the rigid ejector pin 1 and the first housing 3 and fixing member 2.

[0091] In some embodiments, the waterproof member 4 can be made of an elastic insulating material such as rubber. This allows for an interference fit between the waterproof member 4, the rigid ejector pin 1, and the wall of the first through-hole 34. This reduces the gaps between the waterproof member 4 and the first housing 3, and between the waterproof member 4 and the rigid ejector pin 1, resulting in a better waterproofing effect.

[0092] FIG. 7 is a partially exploded schematic diagram of an embodiment of the watch body 200 shown in FIG. 2 .

[0093] As shown in FIG7 , the watch body 200 may include a watch body 210 and an elastic connection assembly 220. The elastic connection assembly 220 may be disposed on the watch body 210. The elastic connection assembly 220 may be used to achieve a detachable connection between the watch strap 100 and the watch body 200 and may also be used to transmit electrical signals between the watch strap 100 and the watch body 200. When the watch strap 100 is connected to the watch body 200, the rigid ejector assembly 10 may be electrically connected to the elastic connection assembly 220 and fixedly connected to the elastic connection assembly 220.

[0094] For example, the watch body 210 may include a second housing 211 and a second electronic device 212. The second electronic device 212 and an elastic connection component 220 may be disposed on the second housing 211. The elastic connection component 220 may be electrically connected to the second electronic device 212. The elastic connection component 220 may be used to transmit electrical signals from the second electronic device 212.

[0095] In some embodiments, the watch body 210 may further include a screen 213. The screen 213 is mounted on the second housing 211. The screen 213 may be used for display.

[0096] Exemplarily, the second housing 211 may include a first portion 2111 and a second portion 2112. The first portion 2111 is connected to the second portion 2112. For example, the first portion 2111 and the second portion 2112 may be fixedly connected by screws. The first portion 2111 and the second portion 2112 enclose an interior space of the second housing 211. It will be appreciated that the second housing 211 is divided into two portions to facilitate the installation of the elastic connection assembly 220 and the second electronic device 212.

[0097] When the second electronic device 212 is provided in the second shell 211, the second electronic device 212 can be located inside the second shell 211, or can be embedded in the surface of the second shell 211. The position of the second electronic device 212 can be set according to the functional requirements of the second electronic device 212. For example, when the second electronic device 212 includes a battery, the battery can be provided inside the second shell 211. When the second electronic device 212 includes an electrocardiogram detection electrode, the electrocardiogram detection electrode needs to be in contact with the user's skin when working, so the electrocardiogram detection electrode can be provided on the side surface of the second shell 211 close to the user. The setting position of the first electronic device 21 can be set according to the functional requirements of the first electronic device 21, and this application does not impose any restrictions.

[0098] In some embodiments, the elastic connection component 220 may include an electrical connection component 221 and a quick release component 222. The electrical connection component 221 may be used to electrically connect the rigid ejector pin component 10 of the watch band 100. The quick release component 222 may be used to provide a detachable connection between the watch body 200 and the watch band 100.

[0099] Figure 8 is a schematic structural diagram of an embodiment of the electrical connection assembly 221 shown in Figure 3. Figure 9 is an exploded schematic diagram of an embodiment of the electrical connection assembly 221 shown in Figure 8. Figure 10 is a partial cross-sectional view of an embodiment of the ejector pin connector shown in Figure 8 at section line BB.

[0100] As shown in Figures 8 to 10, the electrical connection assembly 221 may include at least one elastic conductor 2211 and a third housing 2212. For example, the third housing 2212 includes a first end surface 2215 and a second end surface 2216 disposed in opposite directions. The third housing 2212 may have a second passage 2217 extending through the first end surface 2215 and the second end surface 2216. The elastic conductor 2211 may be disposed within the second passage 2217. The ends of the elastic conductor 2211 are exposed from the first end surface 2215 and the second end surface 2216, respectively.

[0101] The number of elastic conductors 2211 can be one or more. Multiple elastic conductors 2211 can transmit different electrical signals respectively. It is understandable that the number of elastic conductors 2211 included in the electrical connection component 221 can be adjusted according to the number of rigid ejector pins 1 included in the rigid ejector pin component 10. The number of elastic conductors 2211 is equal to the number of rigid ejector pins 1. When the watch strap 100 is connected to the watch body 200, the multiple rigid ejector pins 1 and the multiple elastic conductors 2211 are connected one-to-one. The drawings of this application illustrate 8 elastic conductors 2211 and 8 rigid ejector pins 1.

[0102] Illustratively, the elastic conductor 2211 may include a conductive member 2213 and an elastic insulating member 2214. The elastic insulating member 2214 may be connected to the conductive member 2213. The elastic insulating member 2214 may be made of an insulating material and is elastic, capable of deforming under external force. Illustratively, the elastic insulating member 2214 may be made of silicone or plastic.

[0103] The number of conductive members 2213 included in an elastic conductor 2211 can be one or more. For example, the number of conductive members 2213 can be multiple, and the multiple conductive members 2213 are arranged at intervals from each other. The elastic insulating member 2214 can be located between adjacent conductive members 2213. In this case, the elastic insulating member 2214 can be used for insulation between adjacent conductive members 2213. It should be noted that when the number of conductive members 2213 is multiple, the spacing between two adjacent conductive members 2213 in the multiple conductive members 2213 can be different or the same (that is, the multiple conductive members 2213 are arranged in an array).

[0104] Conductive member 2213 can be made of metal or other conductive materials. It is understood that metal materials have greater strength, and conductive member 2213 is less likely to deform under external forces, which could lead to a decrease in electrical connection performance. The shape of conductive member 2213 can also be customized. For example, conductive member 2213 can be a metal block, a metal wire, or metal particles.

[0105] In some embodiments, the conductive member 2213 may be spherical particles. Spherical particles are isotropic; in other words, they exhibit the same properties in all directions. For example, electrical properties such as impedance and withstand voltage are the same. When the conductive member 2213 is spherical particles, the elastic conductor 2211 exhibits better electrical properties in all directions.

[0106] In some embodiments, the plurality of conductive members 2213 and the elastic insulating member 2214 can be formed into an integrated structure through an injection molding process. For example, the plurality of conductive members 2213 can be suspended by a magnetic field array so that there is a certain gap between the conductive members 2213, and then plastic injection molding is performed to form the elastic conductor 2211.

[0107] In some embodiments, the elastic insulating member 2214 can be made of the same material as the third housing 2212, and the conductive member 2213, the elastic insulating member 2214, and the third housing 2212 can be formed into an integrated structure through an injection molding process. In this case, the elastic insulating member 2214 and the third housing 2212 can be a single structural component. This allows the electrical connection assembly 221 to be a single, integral unit, eliminating the need to assemble the elastic conductive member 2211 and facilitating installation.

[0108] FIG11 is a partial cross-sectional view of an embodiment of the wearable device 1000 shown in FIG1 at section line CC.

[0109] As shown in Figure 11, the first shell 3 can be embedded in the watchband body 20, and one end of the first shell 3 can extend from the watchband body 20. Exemplarily, the second end surface 32 of the first shell 3 can be fixedly connected to the watchband body 20. The first end surface 31 of the first shell 3 can extend from the watchband body 20. One end of the rigid ejector pin 1 can extend from the first end surface 31. When the watchband 100 is connected to the watch body 200, the elastic connecting component 220 can be electrically connected to the rigid ejector pin 1. Exemplarily, the rigid ejector pin 1 can resist the elastic conductor 2211, and the elastic conductor 2211 can be deformed, so that electrical conduction is established between the elastic conductor 2211 and the rigid ejector pin 1. It is understood that when the watchband 100 is connected to the watch body 200, the elastic insulating member 2214 can provide a certain buffer stroke to prevent a large force from being generated between the rigid ejector pin 1 and the conductive member 2213, which may cause damage to the rigid ejector pin 1 or the conductive member 2213.

[0110] In some embodiments, the elastic conductor 2211 may include multiple conductive members 2213, with at least some of the elastic insulating members 2214 located between the multiple conductive members 2213. When the watchband 100 is connected to the watch body 200, the elastic insulating member 2214 is compressed, the distance between adjacent conductive members 2213 is reduced, and the elastic conductor 2211 switches from an insulating state to an electrically conductive state, allowing the rigid ejector pin 1 to electrically connect to the conductive members 2213. The electrical signal of the first electronic device 21 can be transmitted to the conductive member 2213 via the rigid ejector pin 1, or the electrical signal of the second electronic device 212 can be transmitted to the rigid ejector pin 1 via the conductive member 2213. It should be noted that when the elastic insulating member 2214 is compressed, the distance between adjacent conductive members 2213 is reduced, which means that the distance between at least some of the adjacent two conductive members 2213 is reduced, and it is not necessary for the distance between all adjacent conductive members 2213 to be reduced. The elastic insulating member 2214 is compressed, and the distance between some adjacent conductive members 2213 among the plurality of conductive members 2213 may be reduced, thereby forming an electrically conductive path that can be used to transmit electrical signals.

[0111] It will be appreciated that by providing the elastic insulating member 2214, when the watchband 100 is connected to the watch body 200, the elastic insulating member 2214 is compressed, reducing the distance between adjacent conductive members 2213, allowing multiple conductive members 2213 to form an electrically conductive path. Furthermore, the greater the number of conductive members 2213, the more compressed the elastic insulating member 2214 is, and the less affected the direction of the resisting force from the rigid ejector pin 1 is. This makes it easier to form an electrically conductive path between the multiple conductive members 2213, and the electrical connection reliability of the elastic conductor 2211 is enhanced. When the watchband 100 and the watch body 200 are detached, the elastic insulating member 2214 returns to its original shape, increasing the distance between the conductive members 2213 and preventing the multiple conductive members 2213 from forming an electrically conductive path. When the watchband 100 and the watch body 200 are disconnected, the elastic conductor 2211 is uncharged, reducing the risk of corrosion.

[0112] In some embodiments, when the watchband 100 and the watch body 200 are disconnected, the length of the elastic insulating member 2214 along the first direction is L1. When the watchband 100 is connected to the watch body 200, the minimum length of the elastic insulating member 2214 along the first direction is L2. The first direction is the direction in which the rigid ejector pin 1 faces the conductive member 2213 when the watchband 100 is connected to the watch body 200. The difference between L1 and L2 is in the range of 0.1 mm to 1 mm. It should be noted that when the watchband 100 is connected to the watch body 200, the contact surface between the elastic insulating member 2214 and the rigid ejector pin 1 may be uneven. The elastic insulating member 2214 can have multiple lengths along the first direction, with L2 taking the minimum value. It is understood that when the watchband 100 is connected to the watch body 200, the elastic insulating member 2214 can achieve electrical continuity between the conductive member 2213 and the rigid ejector pin 1 with minimal deformation, which helps reduce the volume of the watch body 200.

[0113] In some embodiments, the second shell 211 may be provided with a third through hole 2113. The opening of the third through hole 2113 may be provided on the side of the second shell 211. The third through hole 2113 may connect the interior and exterior spaces of the second shell 211. The exterior space refers to the space where the wearable device 1000 is located. The electrical connection component 221 may be provided in the third through hole 2113. When the strap 100 is connected to the watch body 200, one end of the rigid thimble 1 may be electrically connected to the elastic conductor 2211 in the third through hole 2113. In this way, the effect of dust and other impurities in the exterior space on the reliability of the electrical connection between the rigid thimble 1 and the elastic conductor 2211 can be reduced.

[0114] In some embodiments, the strap body 20 may further include a first circuit board 22. The first circuit board 22 may be fixed to the second end surface 32 of the first shell 3. The rigid ejector pin 1 may be electrically connected to the first circuit board 22. Exemplarily, the rigid ejector pin 1 may be electrically connected and fixedly connected to the first circuit board 22 by welding. The first circuit board 22 may be electrically connected to the first electronic device 21. Exemplarily, the first circuit board 22 may include multiple first signal transmission lines (not shown), and different first signal transmission lines correspond to electrically connected different first electronic devices 21. Multiple rigid ejectors 1 may be electrically connected to multiple first electrical signal transmission lines one by one. In this way, multiple rigid ejectors 1 can transmit electrical signals of multiple first electronic devices 21. In other embodiments, the electrical signals of multiple first electronic devices 21 may also be transmitted to multiple rigid ejectors 1 respectively through other electrical connection structures (such as flexible circuit boards, metal traces, etc.).

[0115] In some embodiments, the watch body 210 may further include a second circuit board 214. The second circuit board 214 may be fixed to the second end surface 32 of the third shell 2212. The elastic conductor 2211 may be electrically connected to the second circuit board 214. Exemplarily, the elastic conductor 2211 may be electrically and fixedly connected to the first circuit board 22 by welding. The second circuit board 214 may be used to electrically connect the second electronic device 212. Exemplarily, the second circuit board 214 may include multiple second signal transmission lines (not shown), with different second signal transmission lines correspondingly electrically connected to different second electronic devices 212. Multiple elastic conductors 2211 may be electrically connected to the multiple second electrical signal transmission lines in a one-to-one correspondence. In this way, the multiple elastic conductors 2211 can transmit electrical signals of the multiple second electronic devices 212. In other embodiments, the electrical signals of the multiple second electronic devices 212 may also be transmitted to the multiple elastic conductors 2211 respectively through other electrical connection structures (such as flexible circuit boards, metal traces, etc.).

[0116] In other embodiments, the elastic conductor 2211 may also be a metal terminal with a bent structure (not shown). When the watchband 100 is connected to the watch body 200, the rigid ejector pin 1 abuts against the metal terminal, causing the metal terminal to deform and move toward the interior of the second housing 211, electrically connecting to the second electronic device 212. This allows the electrical signal from the second electronic device 212 to be transmitted to the watchband body 20 via the metal terminal and the rigid ejector pin 1. When the watchband 100 and watch body 200 are disconnected, the metal terminal returns to its undeformed state, and insulation is established between the metal terminal and the second electronic device 212.

[0117] FIG. 12 is an enlarged schematic diagram of an embodiment of the structure shown in FIG. 11 at position D. FIG.

[0118] As shown in Figures 6 and 12, the waterproof component 4 can partially extend out of the first end surface 31 of the first shell 3. The waterproof component 4 may include a raised portion 41 and a main body portion 42 (the raised portion 41 and the main body portion 42 are divided by a dotted line in Figure 12), and the raised portion 41 may be connected to the side of the main body portion 42 close to the first end surface 31. The raised portion 41 is annular and is arranged around the rigid ejector pin 1. When the watch strap 100 is connected to the watch body 200, the raised portion 41 can abut against the second shell 211, thereby enclosing a sealed space. Prevent external water vapor from flowing along the gap between the first shell 3 and the second shell 211 to the position where the elastic conductor 2211 and the rigid ejector pin 1 are electrically connected, causing leakage.

[0119] In some embodiments, there can be multiple rigid ejector pins 1 and multiple raised portions 41, with the multiple raised portions 41 being connected to the main body 42 at intervals. The multiple raised portions 41 and the multiple rigid ejector pins 1 are arranged in a one-to-one correspondence. Thus, when the multiple rigid ejector pins 1 and the multiple elastic conductors 2211 are electrically connected in a one-to-one correspondence, water vapor can be prevented from flowing from the position of the first elastic conductor 2211 to the position of the adjacent elastic conductor 2211, reducing the risk of series connection between different currents. This ensures that adjacent rigid ejector pins 1 are insulated from each other, as well as adjacent elastic conductors. The electrical connection reliability between the watchband 100 and the watch body 200 is better.

[0120] Several embodiments of the detachable connection between the watch strap 100 and the watch body 200 will be described below with reference to the accompanying drawings. Figure 13 is a schematic diagram illustrating the assembly of one embodiment of the quick-release assembly 222 and the rigid ejector assembly 10 shown in Figure 7 . Figure 14 is a partial cross-sectional view of one embodiment of the wearable device 1000 shown in Figure 1 taken along section line EE.

[0121] As shown in Figures 13 and 14, the quick-release assembly 222 may include a clamping assembly 2221 and a button assembly 2222. The clamping assembly 2221 and the button assembly 2222 are fixed to the second housing 211 at intervals. The clamping assembly 2221 can be used to secure the watchband 100. The button assembly 2222 can be used to remove the watchband 100 from the watch body 200.

[0122] For example, the first housing 3 is provided with a groove 35. The groove 35 may be located on the portion of the first housing 3 that extends beyond the watchband body 20. When the watchband 100 is connected to the watch body 200, part of the retaining assembly 2221 abuts within the groove 35. Thus, the relative position between the first housing 3 and the second housing 211 is fixed by the retaining assembly 2221, allowing the first housing 3 to be fixedly connected to the watchband body 20, and the watchband 100 to be fixedly connected to the watch body 200. It will be appreciated that the groove 35 serves as a positioning mechanism. When the watchband 100 is installed on the watch body 200, once the retaining member 2224 enters the groove 35, it abuts against the first housing 3 along the direction of installation of the watchband 100. At this point, the user will noticeably feel an increase in resistance. This allows the user to determine whether the watchband 100 is installed successfully based on the amount of resistance encountered during insertion.

[0123] For example, the retaining assembly 2221 can be fixedly installed in the third through hole 2113. The second end surface 32 of the first shell 3 can be fixedly connected to the watchband body 20. The first end surface 31 of the first shell 3 can extend out of the watchband body 20. The groove 35 of the first shell 3 can be located in the portion of the first shell 3 that extends out of the watchband body 20. When the watchband 100 is connected to the watch body 200, the first shell 3 can be inserted into the third through hole 2113, and the retaining assembly 2221 securely installs the first shell 3 in the third through hole 2113. It can be understood that by securing the first shell 3 of the watchband 100 in the third through hole 2113, the watchband 100 and the watch body 200 are securely connected. The wearable device 1000 is generally aesthetically pleasing.

[0124] In some embodiments, the retaining assembly 2221 may include a first spring 2223 and a retaining member 2224. One end of the first spring 2223 is fixedly connected to the second housing 211, and the other end is fixed to the retaining member 2224. When the rigid ejector assembly 10 is connected to the quick-release assembly 222, the first spring 2223 is compressed, and at least a portion of the retaining member 2224 is abutted within the groove 35.

[0125] It can be understood that when the watch strap 100 needs to be installed on the watch body 200, the first shell 3 is aligned with the third through hole 2113 and inserted, the first spring 2223 is compressed, and the clamping member 2224 retreats. When the groove 35 reaches near the clamping member 2224, the clamping member 2224 can enter the groove 35. At this time, the first spring 2223 is in a compressed state. Under the action of the first spring 2223, it resists the first shell 3, so that the first shell 3 can be fixed on the second shell 211.

[0126] In some embodiments, there may be multiple retaining assemblies 2221, and the number of grooves 35 may be equal to the number of retaining assemblies 2221. When the watchband 100 is connected to the watch body 200, the multiple retaining assemblies 2221 are disposed on both sides of the first housing 3, corresponding one-to-one with the grooves 35. As shown in Figures 13 and 14, there may be two retaining assemblies 2221, and the number of grooves 35 may also be two, with the two grooves 35 disposed on either side of the first housing 3. When the quick-release assembly 222 is connected to the rigid ejector assembly 10, the two retaining assemblies 2221 are located on either side of the first housing 3, respectively retaining within the two corresponding grooves 35.

[0127] In some embodiments, the button assembly 2222 is movably connected to the watch body 210, and the button assembly 2222 can be spaced apart from the first shell 3. When the button assembly 2222 moves in the second direction, the button assembly 2222 abuts against the holding assembly 2221, and the holding assembly 2221 exits the groove 35. The second direction can be the direction from the inner side of the second shell 211 to the outer side. The inner side of the second shell 211 refers to the side of the second shell 211 that is close to the user's skin when the user wears the wearable device 1000. The outer side of the second shell 211 refers to the side of the second shell 211 that is away from the user's skin when the user wears the wearable device 1000.

[0128] Illustratively, the button assembly 2222 may include a second spring 2225 and a button 2226. The second housing 211 may be provided with a fourth through hole 2114. The fourth through hole 2114 may connect the interior and exterior of the second housing 211. The opening of the fourth through hole 2114 may be located on the inner surface of the second housing 211. One end of the second spring 2225 is fixedly connected to the button 2226, and the other end abuts against the fourth through hole 2114. The second spring 2225 is in a compressed state, exerting a holding force on the button 2226 to secure the button 2226 and prevent it from shaking.

[0129] When the user needs to remove the strap 100, he can press the button 2226, so that when the button 2226 moves along the second direction, the second spring 2225 is compressed, and the button 2226 presses against the holding piece 2224, so that the first spring 2223 is compressed, and the holding piece 2224 withdraws from the groove 35. The first shell 3 can be withdrawn from the third through hole 2113, thereby realizing the rapid disassembly of the strap 100 and the watch body 200.

[0130] The present application specifically introduces several watch straps 100 in combination with the accompanying drawings. The watch strap 100 includes a rigid ejector pin assembly 10 and a watch strap body 20. The rigid ejector pin assembly 10 includes a rigid ejector pin 1, a fixing member 2 and a first shell 3. The first shell 3 can be fixedly connected to the watch strap body 20. The fixing member 2 is fixed between the rigid ejector pin 1 and the first shell 3. The rigid ejector pin 1 is an integral structural member for transmitting electrical signals. It can be understood that compared with the solution of setting an elastic ejector pin for electrical signal transmission, the rigid ejector pin 1 of the present application does not undergo compression deformation and will not cause jamming problems due to incorrect force direction. In other words, the rigid ejector pin 1 does not have jamming problems and has better reliability. In addition, the rigid ejector pin 1 has a simple structure, does not require a later assembly process, has a simple preparation process, and has a low preparation cost. When the watch strap 100 needs to be replaced, the replacement cost is low.

[0131] When the watchband 100 is applied to the wearable device 1000, the wearable device 1000 may include the watchband 100 and a watch body 200. The watchband 100 may be detachably connected to the watch body 200. The watch body 200 may include a watch body main body 210 and an elastic connecting assembly 220. The elastic connecting assembly 220 may be disposed on the watch body main body 210. The elastic connecting assembly 220 may be used to electrically connect the rigid ejector pin 1 and fix the first housing 3. When the watchband 100 is connected to the watch body 200, the electrical connecting assembly 221 may include at least one elastic conductor 2211. The rigid ejector pin 1 may abut against the elastic conductor 2211, and the elastic conductor 2211 may deform, thereby achieving electrical conduction between the elastic conductor 2211 and the rigid ejector pin 1. It is understood that when the watchband 100 is connected to the watch body 200, the rigid ejector pin 1 does not experience any stuck issues, and the electrical reliability between the watchband 100 and the watch body 200 is excellent.

[0132] In other embodiments, the positions of the rigid ejector pin assembly 10 and the elastic connecting assembly 220 shown above can also be interchanged. That is, the rigid ejector pin assembly 10 can be set on the watch body 210, and the elastic connecting assembly 220 can be correspondingly set on the watch band body 20.

[0133] In other embodiments, the wearable device 1000 may include a watchband 100, a watch body 200, and an auxiliary watchband. The auxiliary watchband is a watchband that is not equipped with electronic components and is used only to secure the watch body 200. In other words, when the wearable device 1000 has two watchbands, the second electronic component may be installed on only one of the watchbands.

[0134] FIG15 is a schematic structural diagram of an embodiment of the elastic connector 2000 provided in the present application.
