Abstract
Description
Technical Field
[0001] This application relates to the field of device charging technology, and further to a charging structure and a watch. 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 and a watch that can solve the problems in the prior art by integrating the charging function into the watch band 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 main unit and two wearing components. One end of each of the two wearing components is connected to opposite sides of the main unit, and the other end of each wearing component is detachably connected to secure the wearable device to a predetermined location. The charging structure includes:
[0005] Energy storage module and two sets of power supply components;
[0006] The energy storage module is installed in the wearable device and is electrically connected to the motherboard of the wearable device to supply power to the wearable device.
[0007] The two sets of power supply components are respectively disposed on the corresponding wearable components. Each set of power supply components includes a charging part and an electrical connector. The charging part is disposed at the end of the wearable component away from the main device. The electrical connector is embedded inside the wearable component. The charging part is electrically connected to the energy storage module through the electrical connector.
[0008] When the two wearable devices are separated, the charging parts on the two wearable devices can respectively dock with the charging parts of the charging base to form a power supply path to charge the device; when the two wearable devices are connected, the charging parts on the two wearable devices do not contact each other.
[0009] In some embodiments, the wearable device has an adapter hole, and at least a portion of the charging unit is exposed through the adapter hole corresponding to the wearable device to make contact with the charging contacts of the charging base.
[0010] In some embodiments, the power supply path is a closed loop;
[0011] The charging unit has metal electrode contacts. One electrode contact on the wearable device is a positive contact, and the other electrode contact on the wearable device is a negative contact. The positive contact and the negative contact are respectively connected to different charging contacts on the charging base to form a current loop.
[0012] In some embodiments, the charging structure further includes a protective portion disposed corresponding to the power supply component and located at the end of the wearable piece away from the device host; the protective portion covers the charging portion by magnetic attraction or snap fastening to prevent the charging portion from being exposed to the outside.
[0013] In some embodiments, the power supply path is an electromagnetic induction path;
[0014] The wearable component is a closed structure at least on the side away from the device host, and the charging unit includes at least one wireless charging coil, which is encapsulated inside the corresponding wearable component. The wireless charging coil is electrically connected to the energy storage module through the electrical connector.
[0015] In some embodiments, the energy storage module includes a battery cell and a charging management chip;
[0016] The battery unit is disposed inside the device host or in the hollow cavity of any one or two of the wearable components. The charging management chip is electrically connected to the battery unit and is used to control the charging current and voltage.
[0017] In some embodiments, the charging structure includes a magnetic attraction structure, which includes at least one pair of magnetic elements with opposite polarities. The magnetic elements are respectively disposed at the ends of different wearable parts on the side away from the device host, to assist in the docking of the corresponding charging part and charging base.
[0018] In some embodiments, the magnetic element is a ring magnet, and in each of the wearable devices, the ring magnet is arranged around the outer periphery of the charging part, and a waterproof sealing structure is provided between the inner periphery of the ring magnet and the outer periphery of the charging part.
[0019] In some embodiments, the electrical connector is a flexible circuit board, which is embedded along the length of the corresponding wearable component and has its two ends welded to the welding contact points of the corresponding charging part and the energy storage module, respectively.
[0020] Another aspect of this application also provides a watch, comprising:
[0021] The watch body and two watch straps located on both sides of the watch body;
[0022] Any of the above charging structures;
[0023] At least one of the two watch straps is provided with a power supply component of the charging structure, which is used to supply power to the watch body through the power supply component.
[0024] Compared with the prior art, the charging structure and watch provided in this application have the following advantages:
[0025] 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

[0040] 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.
[0041] 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.
[0042] 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:
[0043] 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.
[0044] In one embodiment, refer to the appendix to the specification. Figures 1 to 4 The present application describes a charging structure that can solve the problems in the prior art by integrating the charging function into the wearable device 2 without the need for additional charging cables.
[0045] 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.
[0046] Specifically, such as Figure 2 As shown, the wearable device includes a device host 1 and two wearing parts 2 respectively connected to opposite sides of the device host 1. The other ends of the two wearing parts 2 can be detachably connected so that the wearable device can be securely worn on the user's wrist or other preset parts.
[0047] The charging structure mainly includes two sets of power supply components 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.
[0048] Optionally, the energy storage module is a flexible rechargeable battery, which can be reasonably arranged according to the structure of the wearable component 2, ensuring wearing comfort while improving the overall battery life of the device.
[0049] Two sets of power supply components are respectively disposed within the corresponding wearable parts 2; in other words, each wearable part 2 is provided with a power supply component. Each set of power supply components includes a charging part 31 and an electrical connector 32. The charging part 31 is disposed at the end of the wearable part 2 away from the device host 1, for example, on the outer surface of the end of the wearable part 2, and can form a docking connection with the external charging base 4.
[0050] 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 4 to improve the convenience and smoothness of user operation.
[0051] 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 transmission of electrical energy.
[0052] 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.
[0053] It should be noted that, in the design of this embodiment, as Figure 3 and Figure 4 As shown, when the two wearable parts 2 are separated, the charging parts 31 respectively provided on the two wearable parts 2 can be connected to the charging parts of the externally provided charging base 4 to form a power supply path for inputting external electrical energy into the energy storage module to charge the device.
[0054] When the two wearable parts 2 are connected, the two charging parts 31 are designed not to contact each other in terms of structure and position, so as to avoid accidental contact between the charging parts 31 and cause a short circuit.
[0055] It should be noted that in this embodiment, "power supply path" refers to the path through which electrical energy is transmitted from the charging unit 31 to the energy storage module, including but not limited to the following forms: 1. Physical closed loop: a current loop is formed through a conductor (such as a wire or probe); 2. Electromagnetic induction path: energy is transmitted through the magnetic field coupling of the wireless charging coil.
[0056] Based on the content of this embodiment, optionally, a buckle structure is provided between the two wearable parts 2 to achieve a detachable connection. A magnetic attraction component can also be provided to assist in docking. Specifically, mechanical buckles or plugs are provided at the ends of the two wearable parts 2 to cooperate with the magnetic attraction component to increase the locking stability of the structure. It can be understood that quick alignment is achieved by magnetic attraction and fastening, and then the buckle structure is used to achieve firm fixation, which can effectively prevent the wearer from falling off due to external force during the wearing process, and improve the safety and reliability of use.
[0057] In a specific implementation, the buckle structure may include a connector at the end of one wearable piece 2 and a slot or groove at the corresponding position of the other wearable piece 2. When the two wearable pieces 2 are mated, the magnetic attraction component first achieves initial adsorption and positioning, guides the connector to slide into the groove, and achieves buckle locking through structural limiting.
[0058] 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.
[0059] 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.
[0060] In one embodiment, based on the above embodiment, the wearable part 2 is provided with an adapter hole, and at least part of the charging part 31 is exposed to the outside through the adapter hole so as to form direct conductive contact with the external charging base 4 or charging interface to realize power transmission.
[0061] 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 on the wearable part 2. 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.
[0062] The charging unit 31 may include a metal spring, electrode contacts, or an integrated 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 4 to achieve direct charging without the need for an additional charging cable.
[0063] As can be seen, this structure is more suitable for magnetic charging base 4. The charging structure can achieve automatic alignment through magnetic structure and ensure stable contact of charging contacts, improving charging reliability and ease of use. At the same time, the necessary charging area is exposed through hole 60, while the rest can be hidden inside the wearable part 2, which helps to maintain the overall aesthetics and structural integrity of the wearable part 2.
[0064] Furthermore, a sealing ring can be installed 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.
[0065] 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 contacts of the charging head.
[0066] 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.
[0067] 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 matching charging head is provided with a corresponding 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.
[0068] In one embodiment, such as Figure 6 and Figure 7 As shown, the power supply path is a closed loop, and the charging part 31 has metal electrode contacts. Of the two wearable devices 2, the electrode contacts on one wearable device 2 serve as positive contacts, and the electrode contacts on the other wearable device 2 serve as negative contacts.
[0069] With this configuration, when the wearable device 2 is detached, each electrode contact can be connected to the corresponding conductive contact on the charging head to form a positive and negative closed circuit, thereby enabling the charging of the energy storage module inside the wearable device.
[0070] Even better, in conjunction with the magnetic attraction structure described later, refer to the instruction manual appendix. Figure 4 Magnetic elements 51 with a specific magnetic pole orientation (e.g., a ring magnet with the N pole facing outwards) can be arranged around the positive contact, while magnetic elements 51 with the opposite magnetic polarity (e.g., a ring magnet with the S pole facing outwards) can be arranged around the negative contact. Correspondingly, magnetic attraction structures are also provided in the vicinity of the charging contacts on the charging base 4. These magnetic attraction structures match the magnetic polarity around the positive and negative contacts, so that when the user aligns the wearable device 2 with the charging base 4, it can automatically and correctly align with the device using magnetic guidance.
[0071] Because magnetic poles have natural repulsive / attractive properties, when a user attempts to connect in the wrong orientation, the repulsive force generated by the identical magnetic poles effectively prevents incorrect insertion. This avoids the risks of charging malfunctions, poor contact, or even electrical short circuits that may result from incorrect contact between the electrode contacts and charging contacts. When connected in the correct orientation, the magnetic structure automatically aligns and assists in fitting, achieving precise guidance and rapid pairing between the charging head and the electrode contacts, improving the intuitiveness and success rate of the user's charging operation.
[0072] 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 provides physical shielding and protection for 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.
[0073] 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.
[0074] 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 contacts are located inside the groove, and an elastic sealing membrane is provided covering the top opening of the groove. 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 an electrode contact arrangement area.
[0075] 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.
[0076] When charging is required, the matching charging head has a probe structure and charging contacts 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 groove of the hole, and accurately connect with the electrode contacts, thereby establishing a power supply path.
[0077] 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.
[0078] In one embodiment, (not shown in the figures) the power supply path is an electromagnetic induction path. The wearable device 2 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 entirely encapsulated in the internal structure of the wearable device 2 and electrically connected to the energy storage module built into the wearable device through an electrical connector 32, so as to supply power to the device host 1 in the charging state.
[0079] The power supply component, through the installation of a wireless charging coil, enables energy transfer without the need for exposed conductive structures. Specifically, the wireless charging coil is completely embedded within the wearable device 2, eliminating the need for additional physical openings or adapter interfaces. This significantly reduces the risk of external factors such as liquids and dust corroding the internal electrical structure of the wearable device 2. Furthermore, in this embodiment, the wireless charging coil enables wireless charging of the wearable device, simplifying the charging operation and eliminating the need for precise alignment with the charging port, thus improving charging convenience.
[0080] The wireless charging coil can adopt a thin magnetic core coil structure, embedded in the wearable device 2. For example, it can be thermo-pressed or injection-molded with the TPU, silicone, or polymer composite material layer of the wearable device 2, ensuring its firmness and stability without compromising the aesthetics and flexibility of the wearable device 2. Optionally, the wireless charging coil transmits energy to the externally mounted wireless charging base 4 through resonance or inductive coupling. (The wireless charging coil on the wearable device 2 is the receiver, and the wireless charging coil on the charging base 4 is the transmitter.) When using the device, the user only needs to remove the wearable device and align either side of the wearable device 2 with the wireless charging base 4 to automatically enter the charging state, or both coils can simultaneously receive magnetic field energy to expand the effective charging area.
[0081] In one embodiment, the energy storage module includes a battery cell and a charging management chip.
[0082] The battery unit is located within the internal cavity of the main device 1, or within the hollow cavity of any one or both wearable components 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.
[0083] 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.
[0084] In a specific implementation form, such as Figure 5 As shown, for example, when the power supply unit is located inside the internal cavity of the device host 1, through holes 60 for electrical connection are provided on the opposite connection end faces of the wearable piece 2 and the device host 1, so that the electrical connector 32 can be passed through the through holes 60. The through holes 60 can be small holes or slot structures, and a certain amount of sealing material is provided on the outer edge of the small holes to prevent sweat, moisture, etc. from entering the internal circuit system. When the power supply unit is located inside the wearable piece 2, the same principle applies. Wires are passed through the corresponding through holes 60 to connect the power supply unit and the main board of the device host 1 to achieve electrical connection and thus realize the transmission of electrical energy.
[0085] Understandably, as long as the battery cell forms an electrical closed loop with the corresponding charging unit 31 and the device motherboard through the electrical connector 32, a stable and effective charging process can be achieved.
[0086] In one embodiment, the electrical connector 32 is a flexible circuit board, which is embedded along the length of the wearable device 2 to adapt to the shape and usage habits of the wearable device 2, resulting in stronger structural integration. One end of the flexible circuit board is welded to the charging unit 31, and the other end is welded to the energy storage module, thus constructing a conduction path in the power supply path.
[0087] Understandably, flexible circuit boards can achieve multi-directional bending and compact layout in a limited space, adapting to the internal layout of curved surfaces and structures. Flexible circuit boards can flexibly deform as the wearer 2 bends, without causing circuit damage due to frequent bending, greatly improving the stability and reliability of electrical connections.
[0088] The two ends of the flexible circuit board are respectively soldered to the solder contact points of the charging unit 31 and the energy storage module. The soldering connection method can ensure low resistance and high stability of electrical connection, reduce signal transmission loss and the risk of poor contact, and ensure that power can be efficiently and stably transmitted from the charging unit 31 to the energy storage module, providing stable power support for the normal operation of wearable devices.
[0089] In practical implementation, a dedicated wire groove or fixing structure can be provided inside the wearable component 2 to fix the flexible circuit board and prevent it from shaking or shifting inside the wearable component 2, thus affecting the stability of the electrical connection. Of course, in other embodiments, the electrical connector 32 can also be a conventional wire or similar component with conductive function.
[0090] In one embodiment, the charging structure further includes a magnetic attraction structure to assist in the docking of the corresponding charging part 31 and the charging base 4.
[0091] Specifically, such as Figure 4 As shown, the magnetic attraction structure includes at least one pair of magnetic elements 51 with opposite polarities, such as permanent magnets, magnetic sheets, or neodymium iron boron magnets. The magnetic elements 51 are respectively disposed on different wearing pieces 2, and are located at their respective ends away from the device host 1, i.e., the free ends of the wearing pieces 2. It can be understood that the magnetic attraction structure can be configured to cooperate with the position of the charging unit 31, thereby assisting in the rapid alignment between the charging unit 31 and the charging base 4, simplifying the operation steps and improving charging efficiency. (As described in the above embodiments, it will not be repeated here.)
[0092] In one embodiment, the magnetic element 51 in the magnetic structure is further a ring magnet, and in each wearable 2, the ring magnet is disposed around the outer periphery of the charging part 31.
[0093] Specifically, as described above, the charging unit 31 can be a structure including multiple electrode contacts or a module body encapsulating a wireless charging coil, with a ring magnet surrounding it. The ring magnet can be fixedly connected to the wearable device 2 by means of in-mold injection molding, adhesive fixing, or insert injection molding, which ensures both firmness and contributes to overall lightweight design.
[0094] Optionally, a waterproof sealing structure is also provided between the inner circumference of the annular magnet and the outer circumference of the charging part 31. This waterproof sealing structure can be implemented in one or a combination of the following forms:
[0095] One form is a ring-shaped silicone ring or an O-ring, which is placed in the gap between the ring magnet and the charging part 31 to form an effective waterproof seal through elastic compression; another form is a sealant, which is injected into the gap between the ring magnet and the charging part 31 and allowed to cure to obtain a waterproof seal structure that better fits the gap profile.
[0096] The waterproof sealing structure not only prevents external media such as water vapor, sweat, and dust from seeping between the magnet and the charging unit 31 and affecting the charging performance, but also effectively extends the service life of the magnetic elements and power supply components, ensuring that the wearable device maintains excellent electrical performance and structural stability during daily wear and cleaning.
[0097] In addition, the ring magnet is coaxially arranged with the charging part 31, which helps to achieve accurate positioning of the wearable part 2 when it is attracted, resulting in high docking accuracy.
[0098] In one embodiment, refer to the appendix to the specification. Figure 1 and Figure 2 According to another aspect of this application, this application further provides a watch, the watch including a watch body 71, two watch straps 72 installed on both sides of the watch body 71, and the charging structure in the above embodiment.
[0099] Power supply components for the charging structure are provided in both watch straps 72 (the energy storage module is set according to specific needs), enabling the watch straps 72 to have both wearing and charging functions. The charging part 31 in the power supply component is located at the end of the watch strap 72 away from the watch body 71. When charging is needed, the user only needs to connect the charging part 31 at the end of the watch strap 72 to the corresponding charging dock 4 to start charging.
[0100] 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 72 to the charging dock 4, without having to worry about forgetting to bring the charging cable.
[0101] In one implementation, such as Figure 6 and Figure 7 As shown, the charging part 31 on one watch strap 72 can be used as a watch buckle. That is, the end of the charging part 31 has a limiting flange 311. When you need to wear the watch, simply insert the charging part 31 into the mounting hole 720 of the other watch strap 72.
