[0001] This application relates to the field of device charging technology, and further to a charging structure, a device charging component, and a watch component. Background Technology

[0002] In recent years, with the widespread adoption of wearable devices such as smartwatches and health monitoring bracelets, the convenience and reliability of their charging methods have gradually become key factors in user experience. Currently, mainstream wearable devices still use magnetic contact charging cables or charging cables with USB interfaces to charge the device itself. While these solutions enable power transfer, users need to carry dedicated charging cables with them at all times. These accessories are small, lack a fixed storage structure, and are easily lost when out, exercising, or traveling, causing inconvenience for users when charging. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this application is to provide a charging structure, a device charging component, and a watch component that can solve the problems in the prior art by integrating the charging function into the watch strap without the need for additional wires.

[0004] To achieve the above objectives, this application provides a charging structure disposed in a wearable device. The wearable device includes a device host and two wearing components. One end of each of the two wearing components is respectively connected to opposite sides of the device host, and the other end of each of the two wearing components can form a detachable connection.

[0005] The energy storage module is disposed on the wearable device and electrically connected to the motherboard of the device host to supply power to the device host; the power supply component is disposed on any of the wearable components, and the power supply component includes a charging part and an electrical connector.

[0006] The charging unit is fixedly disposed at the end of the wearable piece away from the device host. The electrical connector is embedded inside the wearable piece. The charging unit is electrically connected to the energy storage module through the electrical connector. In the charging state, the charging unit docks with the corresponding charging base to form a power supply path, thereby supplying power to the device host.

[0007] In some embodiments, the wearable piece having the power supply component has an adapter hole, and at least a portion of the charging part is exposed through the adapter hole on the wearable piece to make contact with the charging contacts of the corresponding charging base.

[0008] In some embodiments, the charging unit includes at least two electrode contacts, at least one of which is a positive contact and at least one is a negative contact. In the charging state, the positive contact and the negative contact are respectively connected to the charging contacts provided on the charging base to form a closed charging circuit with the charging structure, thereby supplying power to the device host.

[0009] The electrode contacts are spaced apart at the ends of the corresponding wearable components, and an insulating structure is provided between adjacent electrode contacts to prevent accidental short circuits caused by unintended conduction between the electrode contacts.

[0010] In some embodiments, in a wearable device provided with the power supply component, the charging portion is flush with or recessed relative to the end of the wearable device on the side away from the main unit.

[0011] In some embodiments, in the wearable device provided with the power supply component, a first docking end is provided at the end of the wearable device near the device host, and a second docking end corresponding to the first docking end is provided on the corresponding side wall of the device host. The first docking end and the second docking end form a sliding connection or a snap-fit ​​connection to realize the detachable connection between the wearable device and the device host.

[0012] The electrical connector has at least a portion exposed on the surface of the first mating end to form an electrical connection with the energy storage module on the device host in the charging state, thereby realizing the transmission of electrical energy between the charging unit and the device host.

[0013] In some embodiments, the first mating end is a pin, and the second mating end is a slot corresponding to the first mating end. The two ends of the slot pass through the opposite end faces of the main body of the device. During assembly, the pin is inserted through the opening on one side of the slot to form a connection between the two. The opening size of the slot is smaller than the maximum outer diameter of the pin to prevent the pin from coming out of the slot.

[0014] And / or,

[0015] The charging port of the device host is located at the second docking end, and the energy storage module is located in the inner cavity of the device host. The energy storage module and the charging port are electrically connected. When the first docking end and the second docking end are connected, the electrical connector and the charging port are in contact and conduction.

[0016] Another aspect of this application also provides a device charging assembly, comprising:

[0017] The charging structure described above;

[0018] A charging dock, wherein the charging dock is provided with at least one docking groove, and the charging contacts of the charging dock are disposed inside the docking groove;

[0019] In the charging state, at least a portion of the wearable piece equipped with the power supply component can be inserted into the docking slot, and the charging part makes contact with the charging contacts to achieve power supply to the device host.

[0020] In some embodiments, the end of the wearable piece with the power supply component located away from the device host is provided with a first magnetic structure, and the charging base is provided with a second magnetic structure that cooperates with the first magnetic structure. When the wearable piece is inserted into the docking slot, the first magnetic structure and the second magnetic structure attract each other to assist in the docking of the charging part and the charging base.

[0021] In some embodiments, the ends of the two wearable components are respectively provided with corresponding snap-fit ​​connection structures, which are used to form a detachable connection between the two wearable components;

[0022] The charging dock is provided with a sliding groove that communicates with the docking groove. When the corresponding wearable piece is inserted into the docking groove, the buckle connection structure on the wearable piece can slide along the extension direction of the sliding groove.

[0023] Another aspect of this application also provides a watch component, including:

[0024] The watch body and two watch straps located on both sides of the watch body;

[0025] The charging structure or the device charging component described above;

[0026] Each of the watch straps is provided with at least one power supply component of the charging structure, which is used to supply power to the watch body through the power supply component.

[0027] Compared with the prior art, the charging structure, device charging component, and watch component provided in this application have the following advantages:

[0028] By placing a charging unit at the end of the wearable device away from the main unit and electrically connecting it to the energy storage module, the wearable device can be directly connected to an external charging dock after being removed from the wearing state. This simplifies the charging process to a certain extent and improves user convenience. At the same time, the structure has a high degree of integration and does not occupy the internal space of the main unit, which is conducive to the miniaturization and appearance optimization of wearable devices. It solves the problem that existing wearable devices generally rely on dedicated charging docks or charging cables, which are inconvenient to carry and easy to lose. Attached Figure Description

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] With the development of wearable devices, especially the widespread adoption of products such as smartwatches and fitness trackers, their portability, lightweight design, and continuous use have become key indicators of user concern. To maintain normal operation, most wearable devices are equipped with rechargeable batteries and require regular charging.

[0044] However, the commonly used charging method in existing technologies involves connecting the device to the main unit via a dedicated magnetic base or a custom charging cable. This charging mode has the following drawbacks:

[0045] On the one hand, users need to carry a dedicated charger or charging cable with them, which increases the burden of use, and problems such as loss or incompatibility are likely to occur when they are out or on business trips, affecting the timeliness and convenience of charging; on the other hand, since the main unit of wearable devices is usually small, the space available for the charging structure is limited, which makes the charging interface prone to interference with the functional circuits and sensor layout, thus limiting the freedom of the overall design.

[0046] In one embodiment, refer to the appendix to the specification. Figure 1 This application describes a charging structure that can solve the problems in the prior art by integrating the charging function into the wearable device without the need for additional charging cables.

[0047] Reference manual attached Figure 1 The present application provides a charging structure that is installed in a wearable device to optimize the charging method and improve convenience.

[0048] Specifically, the wearable device includes a main unit 1 and two wearable parts 2 (such as watch straps) respectively connected to opposite sides of the main unit 1. The other ends of the two wearable parts 2 can be detachably connected through a detachable connection structure so that the wearable device can be securely worn on the user's wrist or other preset parts.

[0049] The charging structure mainly includes a power supply component and an energy storage module. The energy storage module is located in the wearable device and is electrically connected to the motherboard in the device host 1, enabling it to continuously provide power to the device host 1.

[0050] Optionally, the energy storage module is a flexible rechargeable battery, which allows it to be rationally arranged according to the structure of the wearable component 2, ensuring wearing comfort while improving the overall battery life of the device.

[0051] like Figures 1 to 3 As shown, the power supply component is disposed within any of the wearable components 2, and the power supply component includes a charging part 31 and an electrical connector 32. The charging part 31 is disposed at the end of the wearable component 2 furthest from the device host 1, for example, on the outer surface of the end of the wearable component 2, and can form a docking connection with an external charging dock to create a power supply path, thereby supplying power to the device host 1. In this embodiment, the energy storage module can be flexibly disposed within the host or the wearable component 2, as long as it is located within the power supply path to provide power.

[0052] It should be noted that the charging unit 31 can be in the form of metal springs, metal contacts or wireless charging coils to adapt to different charging methods; at the same time, a guide structure can be set between the wearable piece 2 and the charging base to improve the convenience and smoothness of user operation.

[0053] The electrical connector 32 is located inside the wearable piece 2, with one end connected to the charging unit 31 and the other end connected to the energy storage module, for the purpose of completing the power transmission.

[0054] Furthermore, to ensure service life and safety, the electrical connector 32 can be made of a ribbon cable material with bending resistance to meet the multiple bending requirements of wearable devices in daily use.

[0055] Based on the content of this embodiment, optionally, a buckle structure is provided between the two wearing pieces 2. Specifically, the buckle structure may include a connector disposed at the end of one wearing piece 2 and a slot disposed at the corresponding position of the other wearing piece 2. When the two wearing pieces 2 are mated, the connector slides into the slot, and the buckle is locked by the structural limit.

[0056] The connector can be a structure with an elastic tongue. After being inserted into the slot, the elastic tongue rebounds and hooks against the edge of the slot, so that the two wearable parts 2 form a stable lock. The buckle structure has a certain resistance to pull-out, making the structure suitable for wearable devices with a large range of motion.

[0057] In addition, the latching structure can be equipped with a release component or a release mechanism, allowing users to unlock it by pressing or pushing, which improves the security of the latching structure and prevents accidental disengagement.

[0058] In one embodiment, based on the above embodiment, the wearable component 2 with the power supply component is provided with an adapter hole, and at least part of the charging part 31 is exposed to the outside through the adapter hole to form direct conductive contact with the external charging base or charging interface to realize power transmission.

[0059] Under normal circumstances, the adapter hole is located at the end area of ​​the wearable part 2 away from the device host 1. This area is convenient for contact with the external charging device. The adapter hole can be a through hole, blind hole or similar hole structure formed by the wearable part 2 body. Its shape and size are designed to match the structure of the charging part 31 to ensure that the charging part 31 can stably pass through or be embedded in the hole.

[0060] The charging unit 31 may include a metal spring or an integrally packaged charging module. During assembly, at least part of the conductive structure in the charging unit 31 passes through the adapter hole and is exposed on the surface of the wearable part 2, so that when the wearable device is not worn, the user can connect the end of the corresponding wearable part 2 to the charging contact on the corresponding charging base to achieve direct charging without the need for an additional charging cable.

[0061] Furthermore, a sealing ring can be set around the adapter hole or an integrated injection-molded sealing structure can be used to prevent dust or moisture from entering the charging interface, thereby improving the overall environmental adaptability and enhancing the waterproof and dustproof properties of the wearable device.

[0062] In one embodiment, the wearable part 2 is provided with a positioning structure near the adapter hole. The positioning structure is used to form a mechanical alignment with the corresponding structure of the external charging head to achieve accurate docking between the charging part 31 and the charging contact 41 of the charging head.

[0063] Optionally, the positioning structure can adopt a concave-convex mating structure. For example, one or more recesses or protrusions are provided on the edge of the adapter hole of the wearer 2, and corresponding protrusions or recesses are provided on the matching charging head. When the wearer 2 is plugged into the charging head, automatic positioning and orientation correction are achieved by means of the concave-convex structure.

[0064] At the same time, adjusting the specific setting of the concave and convex structure can also play a certain role in preventing mistakes. For example, the wearing part 2 is provided with a protrusion and a recess, and the corresponding charging head is provided with a recess and a protrusion, which can restrict the insertion direction of the charging head and prevent users from inserting it in the wrong direction, resulting in incorrect docking.

[0065] Based on the above, in one embodiment, the charging unit 31 includes at least two electrode contacts 311, each including at least one positive contact and one negative contact, for respectively connecting to the positive and negative charging terminals on the matching charging base. In the charging state, the wearable piece 2, equipped with a power supply component, is inserted into or engaged with the corresponding mating position on the charging base. The positive and negative contacts respectively form stable electrical contacts with the corresponding charging base, thereby establishing a closed current path and achieving stable power supply to the device host 1.

[0066] In addition, electrode contacts 311 are spaced apart at the ends of the corresponding wearable parts 2, and an insulating structure is provided between adjacent electrode contacts 311. This insulating structure can be integrally formed using the insulating material of the wearable part 2 housing itself, thereby simplifying the manufacturing process and improving the overall electrical safety level of the structure.

[0067] Of course, in other embodiments, the insulating structure can be a glue layer. It is understood that after the electrode contacts 311 are assembled, the gaps between the electrode contacts 311 are filled with insulating material (such as silicone or similar insulating colloids). After the insulating material is cured, it can not only reinforce and buffer, but also isolate the electrical connection path and prevent foreign objects from entering the gaps between the probes.

[0068] Optional, such as Figure 3 As shown, the charging part 31 is flush with or recessed relative to the end of the wearer 2 on the side away from the device host 1. In other words, the outer surface of the charging part 31 does not protrude above the end shell surface of the wearer 2, but can be flush with it or slightly recessed inside it.

[0069] Understandably, with this configuration, the charging part 31 is not exposed or protruding, which effectively reduces the risk of wear, deformation or even short circuit of the charging part 31 due to collision, drop or scratch in the non-charging state, thereby significantly improving the durability and reliability of the wearable part 2.

[0070] In one embodiment, the charging structure further includes a protective section disposed at the end of the wearable component 2 away from the device host 1. Understandably, the protective section serves to physically shield and protect the charging component 31, preventing it from prolonged exposure to air, moisture, or external impurities, thereby improving the overall lifespan and environmental adaptability of the wearable device.

[0071] Based on the above, in one specific embodiment, the protective part is a protective cover, which is detachably fixed to the outer end face of the wearable part 2 via a magnetic or snap-on structure. When not charging, the protective cover covers the surface of the charging part 31, forming a sealed structure to prevent dust, water droplets, or metallic foreign objects from contacting the charging part 31, thus avoiding problems such as corrosion, short circuits, or accidental triggering. When charging is needed, the user can directly remove or lift the protective cover without the need for tools, making the operation convenient.

[0072] In contrast, in another embodiment, the protective part is an elastic sealing membrane. Specifically, a groove is provided near the end of the wearable part 2, the electrode contact 311 is located inside the groove, and the top opening of the groove is covered by an elastic sealing membrane. Multiple spring pieces are integrated in the elastic sealing membrane, and the spring pieces are distributed in a ring array in a designated area of ​​the elastic sealing membrane. Each ring array corresponds to the arrangement area of ​​one electrode contact 311.

[0073] In its natural state, the individual spring pieces on the elastic sealing membrane are in a free and unforced state, and their circumferential edges form a continuous closed interface with other parts of the sealing membrane, thereby effectively preventing external liquids, dust or foreign objects from entering the wearer 2 and forming good daily protection.

[0074] When charging is required, the matching charging head has a probe structure and charging contacts 41 are arranged according to the distribution of the spring contacts. When the user aligns the charging head with the end of the wearable device 2, the corresponding probe will press the spring contact at the corresponding position. Under the pressure, the spring contact will undergo local elastic deformation, forming a temporary through hole. The diameter of the through hole matches the charging head probe, allowing the probe to pass through the elastic sealing membrane, extend into the hole groove, and accurately connect with the electrode contact 311, thereby establishing a power supply path.

[0075] After charging is complete, the user removes the charging head. With the external pressure released, each spring automatically springs back to its original shape due to the elasticity of its material, resealing the previously opened area and restoring the seal without external force. Understandably, this implementation does not use a protective cover, which reduces the overall weight to some extent and avoids the risk of losing the protective cover.

[0076] In one embodiment, the wearable device 2 equipped with a power supply component is a closed structure at least on the side away from the device host 1. The power supply component includes at least one wireless charging coil, which is encapsulated in the internal structure of the wearable device 2 and electrically connected to the energy storage module inside the wearable device 2 through an electrical connector 32, so as to supply power to the device host 1 in the charging state.

[0077] The power supply component, through the wireless charging coil, achieves energy transfer without the need for exposed conductive structures, thus avoiding issues such as openings and protection required by the charging structure. Specifically, the wireless charging coil is completely embedded in the wearable device 2, eliminating the need for additional physical ports or adapter interfaces, significantly reducing the risk of corrosion to the internal electrical structure of the wearable device 2 by external factors such as liquids and dust. In addition, this embodiment achieves wireless charging of the wearable device through the wireless charging coil, making the charging operation simpler and eliminating the need for precise alignment with the charging port 120, thereby improving charging convenience.

[0078] Optionally, the wireless charging coil transfers energy to an external wireless charging pad via resonant or inductive coupling. When using the device, the user simply needs to remove the wearable device and align the corresponding side of the wearable component 2 with the wireless charging pad to automatically initiate charging.

[0079] In one embodiment, the energy storage module includes a battery cell and a charging management chip.

[0080] The battery unit is located within the internal cavity of the main device 1 or within the hollow cavity of the corresponding wearable component 2. Optionally, the battery unit can be a small, high-energy-density battery such as a flexible battery, a polymer lithium-ion battery, or a solid-state battery. For example, by embedding a flexible battery within the wearable component 2, the battery unit will not occupy the internal space of the main device 1, providing space for other internal components of the wearable device and making the structural design of the wearable device more rational.

[0081] The charging management chip is located on the circuit board inside the device host 1 or wearable device 2 and is electrically connected to the battery unit. It is mainly used to monitor parameters such as current, voltage and temperature in real time during the charging process. This ensures that when the external power supply component charges the energy storage module, the system can intelligently adjust the charging power and realize multi-stage charging curve control such as constant current-constant voltage or trickle-fast charging, thereby improving charging efficiency, extending battery life, and preventing safety issues such as overcharging and overheating.

[0082] In one embodiment, such as Figure 4As shown, in the wearable device 2 equipped with a power supply component, a first docking end 21 is provided at the end of the wearable device 2 near the device host 1. Correspondingly, a second docking end 11 is provided on the corresponding side wall of the device host 1. The first docking end 21 and the second docking end 11 can form a sliding connection or a snap-fit ​​connection, thereby realizing the detachable installation between the wearable device 2 and the device host 1.

[0083] Furthermore, at least part of the end of the electrical connector 32 is exposed on the surface of the first mating end 21. When the wearer 2 is connected to the device host 1, the exposed electrical connector 32 can mate with the energy storage module or its connection port provided in the device host 1 and form an electrical connection.

[0084] Understandably, the mechanical connection between the wearable component 2 and the main unit 1, which involves sliding or snapping, provides a corresponding assembly guide path and limiting function, significantly improving the structural stability during wear and the reliability of repeated assembly. For example, in some embodiments, the first docking end 21 and the second docking end 11 can respectively adopt a dovetail groove with a corresponding slide rail, a positioning post with a corresponding guide hole, or similar structural mating forms.

[0085] Even better, a detection module can be set on the first docking end 21 or the second docking end 11 to detect the connection status between the wearable device 2 and the device host 1, and can transmit the connection status to the user terminal through wireless communication to improve the user experience.

[0086] Based on the above, in one embodiment, the first mating end 21 is a pin and the second mating end 11 is a slot. The two ends of the slot pass through the opposite end faces of the main unit 1. During assembly, the pin slides into the slot from one side opening to achieve a sliding connection between the two.

[0087] The opening of the slot is smaller than the maximum outer diameter of the pin. In other words, the opening of the slot adopts a tapered structure design. For example, a limiting shoulder or tapered edge design that tapers inward in the circumferential direction can be provided at the opening of the slot so that the pin is restricted by its opening after being inserted into the slot, preventing the wearer 2 from slipping off when installed on the device host 1, thereby ensuring the safety and reliability of the device.

[0088] In this embodiment, the body of the pin can be integrally molded from plastic material, and its shape can be cylindrical, elliptical cylindrical or corresponding three-dimensional structure; furthermore, optionally, a limiting structure can be provided between the pin and the slot, so that the pin can form a certain resistance at the insertion end position after being inserted into the slot, to prevent it from shaking or causing axial displacement, thereby enhancing the overall connection stability.

[0089] With the configuration of this embodiment, the wearable part 2 and the device host 1 are fixed by sliding connection of the pin and slot, which makes the assembly between the components simple and quick, and provides more convenient conditions for the subsequent replacement and maintenance of the wearable part 2, thereby enhancing the maintainability and structural expandability of the product.

[0090] For more details, please refer to the instruction manual appendix. Figure 4 The charging port 120 of the device host 1 is located at the second docking end 11. In one embodiment, the charging port 120 is located in the slot of the device host 1, and the energy storage module is located in the inner cavity of the device host 1 and is connected to the charging port 120 by electrical connection, thereby forming an energy receiving and storage path on the device host 1.

[0091] In the assembled state, the wearable part 2, which is equipped with a power supply component, is connected to the device host 1. The first docking end 21 on the wearable part 2 (such as the pin part in the above embodiment) is inserted into the second docking end 11 on the device host 1 (such as the slot in the above embodiment). During the process of the pin part sliding into the slot, the electrical connector 32 exposed on its outer surface will make physical contact with the charging port 120 inside the slot in the insertion termination state, forming an electrical conduction state, thereby completing the closed power transmission path between the charging part 31 and the energy storage module.

[0092] It should be noted that in this embodiment, by setting the charging port 120 at the second docking end 11 (the position of the slot), the electrical connection path and the mechanical connection structure can be integrated in a centralized position, thereby improving the space utilization of the device.

[0093] In a further embodiment, a sealing ring structure can be provided between the first mating end 21 and the second mating end 11 to enhance the protection level of the connection.

[0094] In one embodiment, refer to the appendix to the specification. Figure 3 , Figure 5 and Figure 6 According to another aspect of this application, this application further provides a device charging assembly, including the charging structure in the above embodiments and a charging base 4. The charging base 4 is provided with at least one docking groove 40, and the charging contacts 41 of the charging base 4 are disposed inside the docking groove 40. In the charging state, at least a portion of the wearable member 2, which is provided with the power supply component, can be inserted into the docking groove 40, and the charging part 31 and the charging contacts 41 form contact and conduction, thereby realizing the power supply to the device host 1.

[0095] As can be understood, the docking groove 40 in this embodiment serves as a cavity for docking with the power supply component, and has certain limiting, guiding and alignment functions, which can improve the docking accuracy and stability between the wearable device 2 and the charging base 4, and reduce the risk of docking misalignment. On the other hand, the charging contact 41 is located in the docking groove 40, which to a certain extent prevents external factors such as dust or impurities from corroding the contact and can ensure conductivity stability.

[0096] In this embodiment, the device is connected to the wearable part 2 and the charging dock 4, which eliminates the need for a traditional additional charging cable, making the user's operation more convenient.

[0097] Optionally, the wearable piece 2, which is equipped with a power supply component, has a flat end on the side away from the device host 1. That is, the end face of this end is a uniform flat surface. The charging part 31 is located on the end face of this flat structure. Correspondingly, the charging contact 41 is set on the bottom wall of the docking groove 40, and the bottom wall is also a flat surface.

[0098] With the above design, when the wearable part 2 is inserted into the charging base 4, its end forms a surface-to-surface contact with the bottom wall of the docking groove 40, which not only effectively ensures the conductivity between each contact point, but also enhances the posture stability of the wearable part 2 in the inserted state, preventing insertion angle deviation or poor contact.

[0099] Of course, in other embodiments, the end of the wearing piece 2 can also be configured as a convex or concave arc-shaped structure. Correspondingly, the bottom wall contour of the docking groove 40 of the charging base 4 is configured as a matching concave or convex structure, thereby forming a tight fit between the arc surfaces during insertion. In this way, a natural guiding effect can be formed, improving the guiding performance of the wearing piece 2 during insertion, while also further optimizing the contact area and improving the contact fit quality and electrical connection stability.

[0100] Furthermore, based on the above embodiments, such as Figure 2 As shown, the end of the wearable piece 2, which is equipped with a power supply component, away from the device host 1, is provided with a first magnetic structure 60. The charging base 4 is provided with a second magnetic structure that cooperates with the first magnetic structure 60. (The second magnetic structure is not shown in the figure. This structure can be embedded in the charging base 4 or fixed to the side wall or bottom wall of the docking groove 40 by means of adhesive or other fixing methods, depending on the setting of the first magnetic structure 60.) During the process of inserting the wearable piece 2 into the docking groove 40, the first magnetic structure 60 and the second magnetic structure attract each other, thereby using magnetic force to assist the wearable piece 2 in positioning, and further enhancing the electrical connection effect between the charging part 31 and the charging base 4.

[0101] As described above, in practical applications, the user's operating experience can be improved by the cooperation of the first magnetic structure 60 and the second magnetic structure. The first magnetic structure 60 and the second magnetic structure can be configured in various ways, as long as they can attract each other. For example, the first magnetic structure 60 and the second magnetic structure can be magnets with opposite polarities, attracting each other when they are close to each other; or, the first magnetic structure 60 can be a metal fitting part, and the second magnetic structure can be a magnet that can attract the fitting part, thereby assisting the docking of the charging unit 31 and the charging base 4. Of course, the reverse can also be achieved, which will not be elaborated here.

[0102] In addition, based on the above-mentioned magnetic structure, it should be noted that in order to prevent the user from inserting the wearer 2 in the wrong direction, which would cause magnetic failure or incorrect docking, the magnetic structure can be designed with an asymmetrical polarity layout. That is, the first magnetic structure 60 and the second magnetic structure are matched in polarity to prevent "foolproofing". For example, the two magnetic structures can attract each other and normally adhere when the wearer 2 is inserted in the correct direction, and repel each other when inserted in the opposite direction, thus eliminating the risk of misinsertion from the structure.

[0103] In one embodiment, referring to the accompanying drawings, the ends of the two wearable pieces 2 are respectively provided with corresponding buckle connection structures 50 to realize a detachable connection between the two wearable pieces 2.

[0104] Furthermore, the charging base 4 is provided with a sliding groove 420 that communicates with the docking groove 40. During the process of the corresponding wearing piece 2 being inserted into the docking groove 40 and entering the charging state, the buckle connection structure 50 on the wearing piece 2 can be guided and slid along the extension direction of the sliding groove 420.

[0105] The sliding groove 420 provides ample structural clearance, preventing the buckle connection structure 50 on the wearable 2 from interfering with the charging base 4 during the insertion of the wearable 2 into the docking groove 40. This improves the stability and smoothness of the insertion process. In addition, the sliding groove 420 guides the movement trajectory of the wearable 2, allowing it to slide stably into the docking groove 40 in a preset direction. This reduces problems such as shaking, deviation, or misinsertion during insertion, thereby ensuring that the charging unit 31 is accurately positioned.

[0106] In one specific embodiment, the buckle connection structure 50 of one wearable part 2 can be a snap-fit ​​post provided at its end, and the buckle connection structure 50 of the other wearable part 2 is a snap-fit ​​hole corresponding to the snap-fit ​​post. The snap-fit ​​is formed by inserting the snap-fit ​​post into the snap-fit ​​hole. The body material of the wearable part 2 has a certain elasticity or flexibility, and can achieve snap-in or pull-out operation through deformation, thereby ensuring good detachability and reusability.

[0107] Furthermore, multiple snap-fit ​​holes can be provided on the corresponding wearing piece 2. By snapping the snap-fit ​​pin into the snap-fit ​​holes at different positions, the effective wearing length formed by the two wearing pieces 2 can be adjusted to meet the wearing and fastening needs of different users.

[0108] In one embodiment, refer to the appendix to the specification. Figure 1 or Figure 5 According to another aspect of this application, this application further provides a watch assembly, which includes a watch body (which can be regarded as the device host 1 in the above embodiments), two watch straps installed on both sides of the watch body (which can be regarded as the wearing member 2 in the above embodiments), and the charging structure or the device charging component in the above embodiments.

[0109] At least one of the two watch straps is equipped with a power supply component for the charging structure, enabling the watch strap to function as both a wearable device and a charging station. When charging is required, the user simply connects the charging section 31 at the end of the watch strap to the corresponding charging dock 4 to begin charging.

[0110] This application solves the problem of having to find and connect a charging cable when charging a traditional watch, making charging more convenient. In daily life, whether in the office, at home, or on the go, users can easily charge their watches by simply connecting the watch strap to the charging dock 4, without having to worry about forgetting to bring the charging cable.

[0111] As can be seen from the above, this embodiment can use the device charging component in the above embodiment. It can be understood that the watch component in this embodiment is a matching combination of the watch body, the watch strap with charging function and the charging base 4. When the user operates, the watch strap is inserted into the docking slot 40 of the charging base 4 to form a power supply path, thereby supplying power to the watch body.

[0112] It should be noted that the above embodiments can be freely combined as needed. The above are merely optional embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
