Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to wristbands and wearable devices thereof. Background Technology

[0002] In the wearable device field, products such as smartwatches and smart bracelets are becoming increasingly popular, bringing numerous conveniences to people's lives, especially playing an important role in health monitoring. Among them, heart rate monitoring, as a key health indicator, has attracted much attention from consumers.

[0003] Currently, most mainstream smartwatches and smart bands on the market achieve heart rate monitoring by integrating sensors and related circuitry into the device's head unit. Specifically, core components such as the battery and control circuit board are concentrated within the head unit of the watch or smart band, while sensors are installed in specific locations on the head unit. These sensors collect physiological signals through contact with the skin, thereby monitoring health data such as heart rate. While this design meets basic health monitoring needs to a certain extent, it also has some significant limitations.

[0004] On the one hand, due to limited space in the watch face, integrating multiple components makes the watch face larger and heavier, which can cause a burden on users during prolonged wear and affect wearing comfort. On the other hand, for many traditional watches and fitness trackers that only have basic functions such as time display and lack health monitoring functions, if users want to add health monitoring functions such as heart rate monitoring, they often need to purchase a brand new smart device. This not only wastes resources but also increases the user's economic costs. Utility Model Content

[0005] Based on this, a wristband and wearable device thereof are provided to improve wearing comfort and reduce the economic cost for users.

[0006] A wristband, comprising:

[0007] The belt has a charging section at one end, and a first channel runs through it along its width on the side of the belt near the charging section; wherein the belt is configured as a bendable structure.

[0008] A flexible pressure detection element is integrally formed with the belt body and bends synchronously with the belt body. The flexible pressure detection element is electrically connected to the charging unit.

[0009] A spring ear structure is disposed within the first channel; wherein the spring ear structure is configured as a retractable structure, and at least one end of the spring ear structure is movable relative to the strap.

[0010] In one embodiment, the flexible pressure detection element includes a pressure detection element, a power supply unit, and a monitoring module; the monitoring module is disposed on the pressure detection element and is electrically connected to the power supply unit; the power supply unit is disposed on the pressure detection element or the belt body;

[0011] The pressure sensing element is integrally formed with the belt body.

[0012] In one embodiment, the pressure sensing element is made of a pressure film material.

[0013] In one embodiment, the pressure sensing element and the belt are integrally formed by injection molding.

[0014] In one embodiment, the spring ear structure includes:

[0015] The first and second new ear bodies are arranged along the length of the first channel and are spaced apart.

[0016] A first driving body is disposed between the first new ear body and the second new ear body;

[0017] The second driving body is provided on the first and / or the second new ear body. The second driving body is configured to move along the length direction of the first channel under the action of electromagnetic force when the first driving body is energized, and drive the first and / or the second new ear body to move.

[0018] And an elastic element connected to the first driving body and the second driving body, the elastic element being configured to drive the second driving body to move relative to the first driving body.

[0019] In one embodiment, the first driving body is fixedly connected to the first channel, and the second driving body is configured to move away from the first driving body under the action of electromagnetic force when the first driving body is energized. The second driving body drives the first spring ear to move until one end of the first spring ear extends out of the first channel.

[0020] In one embodiment, the first driving body is fixedly connected to the first channel, and the second driving body is configured to move toward the first driving body under the action of electromagnetic force when the first driving body is energized. The second driving body drives the first spring ear to move until one end of the first spring ear is retracted into the first channel.

[0021] In one embodiment, the belt is provided with a limiting groove, which is connected to the first channel;

[0022] A limiting block is provided on the first and / or the second spring ear body, and the limiting block is movably disposed in the limiting groove.

[0023] In one embodiment, the spring ear structure further includes a switch disposed on the belt body, the switch being configured to control the on / off state of the first drive body.

[0024] A wearable device includes a watch face and two wristbands as described above, the two wristbands being symmetrically arranged on both sides of the watch face, and the wristbands being detachably connected to the watch face.

[0025] The aforementioned wristband and its wearable device, by integrating a flexible pressure sensor with a bendable band, depart from the traditional design that concentrates core components such as heart rate monitoring on the watch face. This structure distributes the device's weight, effectively reducing the size and weight of the watch face, significantly reducing the burden on the wrist during extended wear and greatly improving comfort, especially suitable for users who need to wear the device for health monitoring for long periods. The wristband is highly adaptable; its spring bar structure is detachable and retractable within the first channel of the band, allowing for easy connection and disconnection from various watch faces, including traditional watch faces with only basic functions. When users want to add health monitoring functions such as heart rate monitoring to a traditional watch or bracelet, they do not need to purchase a new smart device; they only need to replace the wristband with this one featuring the flexible pressure sensor.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] In some exemplary embodiments, such as Figures 1-4 As shown, a wristband is incorporated into a wearable device, such as a watch, bracelet, or other bracelet-like electronic product. The wearable device includes at least a wristband 1 and a watch face 2, which are detachably connected to facilitate replacement and maintenance of the wristband 1. When the wristband 1 is damaged or the user wants to replace it with a different style or function, a new wristband can be easily removed and installed.

[0040] The wristband 1 includes a band body 11, a flexible pressure detection element 12, and a spring ear structure 13.

[0041] In this embodiment, as Figures 1-4As shown, a charging unit 111 is provided at one end of the strap 11. The charging unit 111 includes, for example, multiple connecting pins 1111, which are arranged at intervals along the width of the strap 11 to facilitate electrical connection with the charging device. One possible implementation is to use the dial 2 as the charging device. When the wristband 1 and the dial 2 are connected, the dial 2 can directly charge the wristband 1. Specifically, the dial 2 can be provided with multiple pins (not shown in the figure), which are connected one-to-one with the multiple connecting pins 1111 to realize the transmission of electrical energy and power the relevant components in the wristband 1. Another possible implementation is that the charging device is a charger, which includes an adapter and a data cable. The adapter is connected to the mains power and converts the mains power into a voltage and current suitable for charging the wristband 1. The adapter is connected to the connecting pins 1111 of the charging unit 111 through the data cable to complete the charging process.

[0042] A first channel 112 is provided along its width direction on the side of the strap 11 near the charging part 111. The first channel 112 penetrates the strap 11. The function of the first channel 112 is to expose part of the structure of the new ear structure 13, so as to facilitate subsequent operations on the new ear structure 13, such as installation, disassembly or adjustment.

[0043] The belt body 11 is designed to be flexible. For example, the belt body 11 is made of plastic, giving it a certain degree of flexibility and elasticity, and is manufactured using injection molding to achieve this flexible structure. For instance, a thermoplastic elastomer can be used, which exhibits the elasticity of rubber at room temperature and can be plasticized and molded at high temperatures. During the manufacturing of the belt body 11, it is processed into the desired shape using injection molding, ensuring that the belt body 11 can be easily bent, wrapped around, and fit snugly on the user's wrist. Simultaneously, the plastic material also possesses a certain degree of wear resistance and corrosion resistance, extending the service life of the belt body 11.

[0044] Alternatively, the strap 11 can be made of fabric, giving it good flexibility and bendability. Different types of fabric can be chosen to meet different needs, such as nylon, which is strong and abrasion-resistant; or cotton, which is soft and comfortable, providing a better wearing experience when against the skin. When manufacturing the strap 11, the fabric can be cut and sewn to form a suitable shape and size, and flexible circuit boards and other components can be embedded inside the fabric to achieve electrical connection with the charging unit 111 and other parts, without affecting the bending performance of the strap 11.

[0045] Alternatively, the strap 11 could be made of leather, enhancing its texture and aesthetics to meet the diverse aesthetic preferences of different users. The leather used would be high-quality leather with a certain degree of flexibility and elasticity, such as calfskin or sheepskin. This ensures strength and durability while also providing good bending performance, allowing it to withstand repeated bending without easily cracking or breaking. Furthermore, a thin, soft, elastic fabric, such as spandex, could be embedded inside the leather to further enhance the strap 11's bending performance and resilience, ensuring it can be easily bent, wrap around the user's wrist, and provide a comfortable wearing experience.

[0046] In this embodiment, as Figures 1-4 As shown, the flexible pressure detection element 12 is integrally set with the belt body 11, ensuring the stability and reliability of the structure. The flexible pressure detection element 12 can bend synchronously with the belt body 11, and its performance and detection accuracy will not be affected by the bending of the belt body 11.

[0047] The flexible pressure detection element 12 is electrically connected to the charging unit 111, and obtains electrical energy from the charging device through the charging unit 111 to ensure its normal operation and realize the detection of pressure and other related data.

[0048] In this embodiment, as Figures 1-4 As shown, the spring ear structure 13 is disposed in the first channel 112. The spring ear structure 13 is configured as a retractable structure, and at least one end of the spring ear structure 13 can move relative to the belt body 11.

[0049] In one embodiment, the spring ear structure 13 is detachably disposed within the first channel 112, making it more convenient and quick to replace or repair the spring ear structure 13.

[0050] In practical use, when it is necessary to connect or disconnect the wristband 1 from the dial 2, the extension and retraction state of the spring bar structure 13 can be adjusted to make it cooperate or separate from the corresponding structure on the dial 2, so as to realize the detachable connection function of the wristband 1 and the dial 2.

[0051] In this embodiment, the wristband 1 integrates the flexible pressure sensing element 12 with the bendable band 11, changing the traditional design that concentrates core components such as heart rate monitoring on the dial 2. This structure distributes the device weight, effectively reducing the size and weight of the dial 2, significantly reducing the burden on the wrist when the user wears the wearable device for extended periods, greatly improving wearing comfort, and is especially suitable for users who need to wear the device for health monitoring for long periods.

[0052] The spring bar structure 13 is retractably disposed within the first channel 112 of the strap body 11, allowing the wristband 1 to be easily connected and detached from various watch faces 2, including traditional watch faces with only basic functions. When users want to add health monitoring functions such as heart rate monitoring to traditional watches or bracelets, they do not need to purchase new smart devices; they only need to replace this wristband 1 with the flexible pressure sensing element 12. In this embodiment, the wristband 1 not only avoids the waste of resources caused by purchasing new devices but also reduces the user's economic costs, providing a more economical and environmentally friendly option.

[0053] In this embodiment, as Figures 1-4 As shown, the flexible pressure detection element 12 can be an ultra-thin flexible pressure film sensor, depending on the actual requirements. The ultra-thin nature of the ultra-thin flexible pressure film sensor allows it to be integrated into different carriers such as bandages, clothing, or electronic skin. When applied to the wristband 1, it provides a virtually imperceptible wearing experience, without causing additional burden or discomfort to the user. The flexible pressure detection element 12 includes a pressure detection element 121, a power supply unit 122, and a monitoring module 123.

[0054] The pressure sensing element 121 is made of pressure diaphragm material and is integrally formed with the belt body 11 by injection molding. The integral molding method ensures the connection stability between the pressure sensing element 121 and the belt body 11, avoiding problems such as detection errors or element detachment caused by weak connection.

[0055] The distance between the projected profile of the pressure sensing element 121 on the belt body 11 and the edge profile of the belt body 11 is less than 5 mm, nearly covering the entire belt body 11; or, the area covered by the pressure sensing element 121 on the belt body 11 is greater than 98%. Large-area coverage enables more comprehensive detection of pressure changes at the contact points between the belt body 11 and the human body, improving the accuracy and reliability of the detection.

[0056] Of course, it is understandable that the area of ​​the aforementioned pressure detection element 121 can also be designed according to ergonomics. For example, a certain number of users' wrist sizes can be sampled, and based on the sampling data, the standard value of the user's wrist can be calculated, and the pulse position of the wrist can be estimated. The area of ​​the pressure detection element 121 can be designed according to the wrist size and pulse position, as long as it can ensure that the pressure detection element 121 can cover the pulse of different groups of people, which also saves resources and avoids waste.

[0057] The power supply unit 122 is used to store electrical energy and provide the power required for the operation of the monitoring module 123. The power supply unit 122 may be a battery, which has stable power supply performance and can meet the long-term operation requirements of the monitoring module 123.

[0058] The power supply unit 122 can be installed on the pressure sensing element 121 or on the belt body 11, depending on the actual design requirements and space layout. For example, if there is sufficient space on the pressure sensing element 121 and wiring is convenient, the power supply unit 122 can be installed on the pressure sensing element 121. If there is a suitable installation location inside the belt body 11 and it is more conducive to the balance of the overall structure, the power supply unit 122 can be installed on the belt body 11.

[0059] The monitoring module 123 is disposed on the pressure detection element 121. The monitoring module 123 includes, for example, multiple chip circuits, which are attached to the pressure detection element 121. The multiple chip circuits work together to process and analyze the pressure signal collected by the pressure detection element 121, such as amplifying, filtering, and converting the signal to a digital signal that can be recognized and processed by subsequent equipment.

[0060] The monitoring module 123 is electrically connected to the power supply unit 122, and obtains power from the power supply unit 122 to ensure its normal operation. This electrical connection can be achieved through wires or other suitable electrical connection methods to ensure that power is stably and reliably transmitted to the various chip circuits of the monitoring module 123.

[0061] To ensure flatness when the belt body 11 is connected to the flexible pressure sensing element 12, a groove 113 can be provided on the belt body 11. The shape and size of the groove 113 are designed according to the external shape of the power supply unit 122 and the monitoring module 123, and are used to accommodate the power supply unit 122 and the monitoring module 123. By providing the groove 113, when the pressure sensing element 121 covers the belt body 11, the unevenness caused by the power supply unit 122 and the monitoring module 123 protruding from the surface of the belt body 11 can be avoided, thereby improving the user experience and making the wristband 1 more comfortable to wear.

[0062] The data collected by the flexible pressure sensing element 12 can be transmitted wirelessly to a smart device via the monitoring module 123. This smart device could be, for example, a watch face 2 connected to the wristband 1, with a touchscreen display for user operation via an application (APP) stored within it. Alternatively, the smart device could be other electronic products, such as mobile phones, tablets, or other portable electronic devices, all with their own internal applications.

[0063] The monitoring module 123 can transmit data to the corresponding APP for data analysis. In this way, users can obtain pressure detection data in real time and realize real-time monitoring of their own health status. For example, during exercise, users can use the watch face 2 or the APP to understand the pressure changes in their wrist in real time, thereby adjusting their exercise posture and intensity to avoid wrist injuries caused by over-exercise or improper posture.

[0064] In some exemplary embodiments, such as Figures 1-5 As shown, the spring bar structure 13 is used for the detachable connection between the wristband and the dial 2. The spring bar structure 13 includes a first spring bar body 131, a second spring bar body 132, a first drive body 133, a second drive body 134, and an elastic element 135. The components work together to achieve convenient assembly and disassembly of the wristband 1 and the dial 2.

[0065] Taking the width direction of the strap 11 as an example, it has a first sidewall 114 and a second sidewall 115 arranged opposite to each other, and a first channel 112 passes through the first sidewall 114 and the second sidewall 115. A first spring bar 131 and a second spring bar 132 are arranged along the length direction of the first channel 112, and are spaced apart. The first spring bar 131 is disposed within the first channel 112, and its end away from the second spring bar 132 passes through the first sidewall 114. The second spring bar 132 is disposed within the first channel 112, and its end away from the first spring bar 131 passes through the second sidewall 115. As long as either the first spring bar 131 or the second spring bar 132 can extend or retract from the sidewall of the strap 11, the strap 11 and the dial 2 can be engaged or disengaged.

[0066] The first driving element 133 is disposed between the first spring ear body 131 and the second spring ear body 132. As the core component for generating the magnetic field, the first driving element 133 provides the force source for the second driving element 134. For example, the first driving element 133 is an electromagnet. When the electromagnet is energized, it generates a magnetic field in a specific direction, thereby exerting a force on the second driving element 134.

[0067] The first raw ear body 131 is provided with a second driving body 134, which is a permanent magnet.

[0068] When the first driving body 133 is energized, the second driving body 134, under the influence of the magnetic field generated by the first driving body 133, is affected by electromagnetic force and moves along the length of the first channel 112, driving the first spring ear 131 to move synchronously. When the end of the first spring ear 131 away from the second spring ear 132 retracts into the first channel 112, the strap 11 and the dial 2 can be separated. When the end of the first spring ear 131 away from the second spring ear 132 passes through the first sidewall 114, the first spring ear 131 is engaged with the corresponding position on the dial 2, realizing the assembly of the strap 11 and the dial 2.

[0069] In one embodiment, the second driving body 134 is disposed at the end of the first spring ear body 131 near the first driving body 133, and the second driving body 134 is disposed close to the first driving body 133, so that the second driving body 134 can quickly respond to the electromagnetic force of the first driving body 133.

[0070] It should be noted that the installation position of the second drive body 134 is not fixed on the first spring ear 131; it can also be set on the second spring ear 132. When set on the second spring ear 132, the second spring ear 132 can also be driven to move when the first drive body 133 is energized, thereby realizing the disassembly and installation operations. If one second drive body 134 is set on each of the first spring ear 131 and the second spring ear 132, then when the first drive body 133 is energized, both the first spring ear 131 and the second spring ear 132 can be driven simultaneously, improving the efficiency of disassembly and installation.

[0071] An elastic element 135 is connected to the first driving body 133 and the second driving body 134, and is used to drive the second driving body 134 to move relative to the first driving body 133. The elastic element 135 is, for example, a spring, which can be a tension spring or a compression spring. The specific form of the spring is designed with reference to the direction of the electromagnetic force. For example, if the electromagnetic force drives the second driving body 134 to move closer to the first driving body 133, a compression spring can be selected. When the electromagnetic force disappears, the spring force of the compression spring will cause the second driving body 134 to return to its initial position. Conversely, if the electromagnetic force drives the second driving body 134 to move away from the first driving body 133, a tension spring can be selected. When the electromagnetic force disappears, the spring force of the tension spring will cause the second driving body 134 to return to its original position.

[0072] The following examples illustrate different configurations of the second driving body 134, the first driving body 133, the first spring ear body 131, the second spring ear body 132, and the elastic element 135 to facilitate further understanding.

[0073] First Example

[0074] The first drive body 133 is fixedly connected to the first channel 112 to ensure its stable position during operation. A second drive body 134 is mounted on the first spring ear 131. The first spring ear 131 is movably disposed within the first channel 112, allowing it to move flexibly along its length within the channel 112. The second spring ear 132 is fixedly connected to the strap 11, with its end away from the first spring ear 131 extending through the first sidewall 114, providing a fixing point for the connection between the strap 11 and the dial 2. The positional relationship between the first drive body 133 and the second spring ear 132 is flexible; they can be fixedly connected or spaced apart, as long as they remain relatively stable and meet actual working requirements. Adjustments can be made based on specific circumstances.

[0075] The dial 2 has two spaced-apart connecting ears 21. One end of the strap 11 with the charging part 111 can be inserted between the two connecting ears 21, and the strap 11 and the two connecting ears 21 are fitted with a gap. This design provides sufficient room for the disassembly and installation of the strap 11 and the dial 2, making the operation more convenient. The inner side of the connecting ear 21 is provided with a blind hole 211. One end of the second spring bar 132 that protrudes from the first side wall 114 can be inserted into the corresponding blind hole 211 to achieve initial positioning.

[0076] When the first driving body 133 is energized, it generates a magnetic field, acting as an electromagnet. Under the influence of this magnetic field, the second driving body 134 moves along the length of the first channel 112, causing the first spring ear 131 to move synchronously. At this time, a repulsive force is generated between the second driving body 134 and the first driving body 133, causing the second driving body 134 to move away from the first driving body 133 until the end of the first spring ear 131 away from the second spring ear 132 passes through the second sidewall 115 and is inserted into the corresponding blind hole 211, completing the installation of the strap 11 and the dial 2.

[0077] An elastic element 135 connects the first drive body 133 and the second drive body 134. In this example, the elastic element 135 is a tension spring. When the second drive body 134 moves away from the first drive body 133, the tension spring accumulates elastic potential energy. When the spring ear structure 13 is de-energized, the tension spring pulls back the second drive body 134, causing it to move closer to the first drive body 133 until the first spring ear 131 retracts into the first channel 112. At this time, the first spring ear 131 retracts from the blind hole 211, and the dial 2 and the strap 11 can be easily separated.

[0078] Furthermore, the location of the second driving body 134 is not limited to the first spring ear 131; it can also be located on the second spring ear 132. When located on the second spring ear 132, the second spring ear 132 is movably disposed within the first channel 112, while the first spring ear 131 is fixed within the first channel 112. The specific arrangement and implementation are the same as those of the first spring ear 131. Alternatively, both the first spring ear 131 and the second spring ear 132 can be movably disposed within the first channel 112. Their arrangement and implementation are similar to those of the single movable spring ear described above, and will not be repeated here.

[0079] This example demonstrates installation via repulsive force driving the first spring bar 131 to move, and disassembly via the pull-back force of a tension spring. The structure is simple and the operation is convenient. During installation, the repulsive force allows the first spring bar 131 to be quickly and accurately inserted into the blind hole 211, ensuring connection stability. During disassembly, the elastic potential energy of the tension spring is released, causing the first spring bar 131 to automatically retract, facilitating the separation of the dial 2 and the strap 11, thus improving assembly and disassembly efficiency.

[0080] Second example

[0081] The first driving body 133 is fixedly connected to the first channel 112. A second driving body 134 is provided on the first spring ear body 131, and the first spring ear body 131 is movably disposed within the first channel 112. The second spring ear body 132 is fixedly connected to the strap body 11, and its end away from the first spring ear body 131 protrudes through the first sidewall 114. The positional relationship between the first driving body 133 and the second spring ear body 132 can also be selected to be fixedly connected or spaced apart according to the actual situation to ensure relative stability.

[0082] When the first drive body 133 is energized, the second drive body 134 is affected by electromagnetic force under the magnetic field generated by the first drive body 133, moving along the length of the first channel 112 and driving the first spring ear 131 to move synchronously. Unlike the first example, an attractive force is generated between the second drive body 134 and the first drive body 133 at this time, causing the second drive body 134 to move closer to the first drive body 133 until the end of the first spring ear 131 away from the second spring ear 132 retracts into the first channel 112. At this time, the dial 2 and the strap 11 can be separated.

[0083] An elastic element 135 connects the first drive body 133 and the second drive body 134. In this example, the elastic element 135 is a compression spring. When the second drive body 134 moves closer to the first drive body 133, the compression spring accumulates elastic potential energy. When the spring ear structure 13 is de-energized, the compression spring resets, thereby pushing the second drive body 134 away from the first drive body 133 until the first spring ear 131 passes through the first sidewall 114 and is inserted into the corresponding blind hole 211, completing the assembly of the dial 2 and the strap 11.

[0084] Similarly, the second driving body 134 can also be disposed on the second spring ear body 132, so that the second spring ear body 132 is movably disposed within the first channel 112, and the first spring ear body 131 is fixed within the first channel 112. The specific arrangement and implementation are the same as when the first spring ear body 131 is movable. The first spring ear body 131 and the second spring ear body 132 can also both be movably disposed within the first channel 112. The arrangement and implementation are similar and will not be repeated here.

[0085] This example uses suction to retract the first spring bar 131 for disassembly, and utilizes the pushing force of a compression spring for installation. During disassembly, the suction quickly disengages the first spring bar 131 from the blind hole 211, facilitating the separation of the dial 2 and the strap 11. During installation, the elastic potential energy of the compression spring is released, providing a stable pushing force to insert the first spring bar 131 into the blind hole 211, ensuring reliable installation. Compared to the first example, the same disassembly and assembly functions are achieved through different force application methods, providing more options for practical applications.

[0086] Third Example

[0087] The first driving body 133 is fixedly connected to the first channel 112. The first driving body 133 is a bistable electromagnet, which has the characteristic of maintaining magnetism even when the power is off. A second driving body 134 is provided on both the first spring ear body 131 and the second spring ear body 132. Both the first spring ear body 131 and the second spring ear body 132 can be movably disposed within the first channel 112, allowing them to move flexibly within the first channel 112.

[0088] When the first driving body 133 is energized, the second driving body 134 is affected by electromagnetic force under the magnetic field generated by the first driving body 133, moving along the length of the first channel 112 and driving the first spring ear 131 to move away from the first driving body 133 until both the first spring ear 131 and the second spring ear 132 are inserted into the corresponding blind holes 211. Due to the characteristics of the bistable electromagnet, it can maintain its magnetism even when the power is off, thus ensuring the stability of the strap 11 and the dial 2 during assembly and achieving a low-energy consumption effect. When disassembly is required, the first driving body 133 is energized again, and its current direction is changed, so that the second driving body 134 is attracted to the first driving body 133, thereby causing the first spring ear 131 and the second spring ear 132 to retract into the first channel 112, completing the disassembly operation.

[0089] This example uses a bistable electromagnet as the first driving element 133. Utilizing its property of maintaining magnetism even when power is off, a stable connection can be maintained between the belt 11 and the dial 2 without continuous power supply after assembly, significantly reducing energy consumption. Furthermore, disassembly is achieved by changing the direction of the current, making operation simple and convenient. Compared to the previous two examples, this method maintains the disassembly and assembly functionality while offering lower energy consumption, making it more suitable for applications with high energy-saving requirements.

[0090] Through the different setup methods described above, the spring bar structure 13 of this disclosure can flexibly adjust the setup and function of each component according to actual needs, achieving efficient and reliable disassembly and assembly of the wristband and dial, and providing different beneficial effects, thus offering diverse solutions for practical applications.

[0091] It should be noted that the power on and off in this embodiment can be controlled by a switch (not shown in the figure). For example, the spring ear structure 13 also includes a switch (not shown in the figure), which may be disposed on the strap 11. The location of the switch can be selected from various options; in this embodiment, it is disposed on the strap 11. Since the strap 11 is a part that users frequently come into contact with during daily operation, placing the switch there makes it convenient for users to easily find and operate the switch when wearing or using the related device, thus improving ease of use.

[0092] The main function of the switch is to control the on / off state of the first driving body 133. Specifically, when the user needs the first driving body 133 to work, such as when the spring bar structure 13 needs to perform specific extension, retraction, or fixing actions, the user only needs to operate the switch to place it in the on state. At this time, current can be smoothly transmitted through the switch to the first driving body 133. After being energized, the first driving body 133 starts to work and performs corresponding actions according to the preset program, thereby realizing the function of the spring bar structure 13, such as extending or retracting the spring bar stem to complete the connection or separation operation with components such as the lugs.

[0093] Conversely, when the user does not need the first actuator 133 to work, or for reasons such as saving power or avoiding accidental operation, the user can put the switch in the off state. Once the switch is off, current cannot be transmitted to the first actuator 133, the first actuator 133 is de-energized and stops working, and the spring ear structure 13 also stops performing related actions and enters a stationary state.

[0094] By setting a switch on the belt 11 to control the on / off state of the first drive body 133, the user can flexibly choose to connect or disconnect the switch according to actual needs, thereby controlling the working state of the spring ear structure 13, which greatly improves the practicality of the product and the user experience.

[0095] In this embodiment, as Figures 1-5 As shown, the belt body 11 is provided with a limiting groove 116, which communicates with the first channel 112. Specifically, the limiting groove 116 is provided on the inner wall of the first channel 112. The number of limiting grooves 116 can be one or two. For example, when there is only one movable spring ear, one limiting groove 116 is sufficient to restrict its movement; if there are two movable spring ear bodies, two limiting grooves 116 can be provided to restrict the movement of each different spring ear body.

[0096] When the first ear body 131 is in a movable state, a limiting block 1311 is provided on the first ear body 131, and the limiting block 1311 is movably disposed in the limiting groove 116.

[0097] On the one hand, the movement distance of the first spring ear 131 can be effectively limited by the cooperation between the limiting block 1311 and the limiting groove 116. During the movement of the first spring ear 131 along the first channel 112, when the limiting block 1311 moves to the end of the limiting groove 116, it will be blocked by the end of the limiting groove 116, thereby preventing the first spring ear 131 from continuing to move, avoiding the first spring ear 131 from leaving the first channel 112 due to excessive movement, and ensuring the normal operation and safe use of the spring ear structure 13.

[0098] On the other hand, the shape of the limiting groove 116 is usually elongated, and its orientation determines the direction of movement of the first spring ear 131. When the limiting block 1311 moves within the limiting groove 116, it can only move linearly along the extension direction of the limiting groove 116. This restricts the direction of movement of the first spring ear 131, preventing misalignment and ensuring that the first spring ear 131 moves stably and accurately within the first channel 112. This, in turn, improves the reliability and stability of the entire spring ear structure 13.

[0099] It is understandable that if the second spring ear body 132 is also movable, then a corresponding limiting block 1311 needs to be set. The specific setting method is similar to that of the first spring ear body 131, that is, according to the movement requirements and actual situation of the second spring ear body 132, a suitable limiting block 1311 is set on the second spring ear body 132 and movably set in the limiting groove 116 corresponding to the second spring ear body 132, so as to limit the movement distance and direction of the second spring ear body 132 and ensure that all movable parts in the entire spring ear structure 13 can work normally and stably.

[0100] In this embodiment, by setting a limiting groove 116 on the inner wall of the first channel 112 of the belt 11 and setting a limiting block 1311 on the movable spring ear body, the movement of the spring ear body is effectively restricted, thereby improving the performance and reliability of the spring ear structure 13.

[0101] This disclosure also provides a wearable device, such as Figures 1-5 As shown, the device includes a dial 2 and two wristbands 1 as described in the above embodiment. The two wristbands 1 are symmetrically arranged on both sides of the dial 2. This symmetrical layout not only conforms to the principles of ergonomics, making the wearable device more balanced and comfortable when worn, reducing the discomfort caused to the user due to one side being too heavy, but also has aesthetic appeal, improving the overall appearance quality of the product.

[0102] Each wristband 1 adopts the structure described in the above embodiments. The wristband 1 achieves a detachable connection between itself and the dial 2 by controlling the extension and retraction states of the second spring bar 132 and / or the first spring bar 131. The operation is simple and easy to implement. The specific connection method has been described in detail in the foregoing embodiments and will not be repeated here.

[0103] Users can easily change the style, color, or material of the wristband 1 according to their preferences, usage scenarios, or seasonal changes. If any part of the wristband 1 or the watch face 2 is damaged, users do not need to send the entire wearable device for repair; they can simply remove the damaged wristband 1 for replacement or repair, greatly reducing repair costs and time.

[0104] The wearable device disclosed herein provides users with a convenient and comfortable user experience through its reasonable structural design and detachable connection method, while also having high practicality and maintainability.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
