Description

Technical Field

[0001] This application relates to the field of magnetic charging technology, and further to a charging port structure, a smartwatch, and a magnetic charger. Background Technology

[0002] In the field of magnetic charging technology, current research mainly focuses on how to improve the magnetic attraction and stability, such as by improving the arrangement of magnets and using new magnetic materials to enhance the magnetic attraction effect. However, less attention has been paid to the waterproof design of the charging port.

[0003] Existing magnetic charging devices typically only have simple waterproofing on the outer casing. While this design may meet basic waterproofing requirements in daily use, its waterproofing performance may gradually decrease under harsher environmental conditions or during long-term use. Once external moisture seeps into the device through the charging probes and other parts, it can damage critical components such as the internal circuit board, thereby affecting the device's lifespan and safety, causing numerous inconveniences and safety hazards for users. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this application is to provide a charging port structure, a smartwatch, and a magnetic charger that can ensure the safety of the internal electronic components of the device and improve the reliability and lifespan of the device's charging.

[0005] To achieve the above objectives, in a first aspect, this application provides a charging port structure for charging wearable devices, comprising:

[0006] The supporting body has a mounting cavity with an opening on one side, and a docking end is provided inside the mounting cavity;

[0007] A magnetic attraction element is disposed in the mounting cavity and avoids the docking end, which is used to assist the charging port structure in magnetic docking with the corresponding device.

[0008] At least two charging probes are located at least partially in the mounting cavity, the charging probes penetrating the respective mating ends to form an electrical connection with the corresponding circuit board on the side of the mounting cavity opposite to the opening;

[0009] A sealing structure is provided around the outer periphery of the charging probe, at least sealing the gap between the charging probe and the docking end.

[0010] In some embodiments, the sealing structure includes a first sealing structure;

[0011] The magnetic attraction element, the docking end, and the charging probe together form a first space within the same mounting cavity. The first sealing structure is located within the first space, thereby simultaneously sealing the gap between the magnetic attraction element and the charging probe, and the gap between the charging probe and the docking end.

[0012] In some embodiments, the first sealing structure includes a first adhesive layer disposed within the first space, the first adhesive layer being formed by injecting adhesive into the first space and after the adhesive has cured;

[0013] Alternatively, the first sealing structure may include a first resilient seal disposed within the first space.

[0014] In some embodiments, one side of the first sealing structure is connected to the bottom of the mounting cavity, and the other side of the first sealing structure extends along the depth direction of the mounting cavity toward the opening side of the mounting cavity to a preset position.

[0015] In some embodiments, the number of mounting cavities is at least two, and each mounting cavity is provided with at least one docking end for docking with the corresponding charging probe; each mounting cavity is provided with at least one magnetic attraction element.

[0016] In some embodiments, the sealing structure includes a second sealing structure disposed between different charging probes to prevent conductive paths from forming between the charging probes in different mounting cavities.

[0017] In some embodiments, in the sealing structure, the second sealing structure is located on the side of the support body away from the bottom of the mounting cavity, so as to close the opening of the mounting cavity.

[0018] In some embodiments, the second sealing structure includes a second adhesive layer, which is formed by injecting adhesive between the charging probes in different mounting cavities and after the adhesive has cured.

[0019] Alternatively, the second sealing structure includes a second resilient seal that surrounds the outer periphery of the corresponding charging probe.

[0020] In some embodiments, the carrier body has a partition between every two mounting cavities, the partition serving to relatively isolate the magnetic elements within adjacent mounting cavities.

[0021] In some embodiments, the partition is erected on the bottom wall of the supporting body;

[0022] And / or, a protruding partition is provided on the side of the partition away from the bottom wall of the supporting body, the partition being able to cooperate with the second sealing structure to form an insulating mating interface between the charging probes of adjacent mounting cavities.

[0023] In some embodiments, the magnetic element is annular, and the mating end is configured as a boss protruding from the bottom of the mounting cavity toward the corresponding opening, with the magnetic element sleeved on the outside of the boss;

[0024] And / or, the outer periphery of the magnetic element is provided with an insulating layer.

[0025] In some embodiments, a limiting portion is provided on the peripheral wall of the charging probe, the limiting portion protruding outward in the radial direction, and the boss has a mounting hole extending through its height direction. When the charging probe is mated with the mounting hole, the limiting portion abuts against the surface of the boss, and the gap between the limiting portion and the boss is sealed by the sealing structure.

[0026] In some embodiments, the charging port structure further includes a top cover, which is connected to the support body from the opening side of the mounting cavity;

[0027] The top cover is provided with an adapter hole for accommodating the assembly and positioning of the charging probe.

[0028] In some embodiments, at least a portion of the adapter hole is configured as a tapered tube with a diameter that gradually decreases along a first direction. The large-diameter end of the tapered tube is positioned close to the support body to form a guide structure on the relative assembly path of the top cover and the charging probe to assist in assembly.

[0029] In some embodiments, the main body portion of the carrier without the docking end is configured as a closed frame to isolate external impurities, and the sealing structure and the carrier together form a sealing barrier for the charging port structure.

[0030] A second aspect of this application also provides a smartwatch, including at least one of the above-described charging port structures.

[0031] A third aspect of this application also provides a magnetic charger, comprising: at least one of the above-described charging port structures.

[0032] Compared with the prior art, the charging port structure, smartwatch, and magnetic charger provided in this application have the following advantages:

[0033] By incorporating a docking end, magnetic elements, and charging probes within the mounting cavity of the main body, the entire charging module achieves high integration and reliable docking. Furthermore, this application features a sealing structure surrounding the charging probes. This sealing structure effectively blocks the gap between the charging probes and the docking end, preventing external moisture from penetrating the device along the charging probes. This significantly enhances the waterproof capability of the charging port, ensuring it maintains excellent sealing even under long-term use or harsh environmental conditions. This prevents short circuits and corrosion of critical internal electronic components due to moisture intrusion, significantly improving the device's safety and lifespan. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0042] To keep the drawings concise, each drawing only schematically shows the parts relevant to the application; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled.

[0043] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0044] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] 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.

[0047] Magnetic charging technology is widely used in wearable electronic devices such as smartwatches and wireless headphones due to its advantages such as convenient connection and good user experience.

[0048] Current research and improvements mainly focus on enhancing magnetic attraction, optimizing alignment structures, and improving charging efficiency. However, less attention has been paid to the waterproof protection design of the charging port itself. Some products achieve waterproofing solely through the overall casing structure; for example, in smartwatches, some manufacturers simply use a sealed casing to prevent moisture from entering the device.

[0049] However, in practical applications, devices may face complex environments such as frequent wearing, cleaning, and outdoor exposure. Especially under conditions of high humidity, high pressure, or long-term use, traditional waterproofing methods relying on sealed outer casings are prone to aging, loosening, or seal failure. In such cases, moisture may seep in through gaps at the magnetic charging interface and enter the device's interior along the charging probes or conductive parts, affecting the stability and safety of critical electronic components such as internal circuit boards and chips. In severe cases, this can even lead to short circuits or device failure, significantly impacting product lifespan and user experience.

[0050] In one embodiment, refer to the appendix to the specification. Figure 1 The charging port structure provided in this application can provide higher protection capabilities to prevent external moisture and other substances from entering the device.

[0051] The charging port structure provided in this application is applicable to magnetic charging scenarios for wearable devices, such as smartwatches, smart bracelets, wireless earphones, and their corresponding charging devices. This charging port structure can effectively improve the protection capability of the charging port and prevent moisture from seeping into it.

[0052] In this embodiment, as Figure 1 and Figure 2 As shown, the charging port structure mainly includes a supporting body 1, a magnetic element 2, at least two charging probes 3, and a sealing structure 4.

[0053] like Figure 3 As shown, the supporting body 1 is used to accommodate and support the various components. The supporting body 1 is provided with a mounting cavity 100 with an opening on one side. The mounting cavity 100 is provided with a docking end 101. The docking end 101 can be a locally formed structural platform or related structural setting, used for docking the charging probe 3.

[0054] The magnetic element 2 is disposed within the mounting cavity 100 to achieve magnetic attraction between the charging port structure and the corresponding device, enabling precise alignment and stable connection between the charging port and the device during charging. It is worth noting that the arrangement of the magnetic element 2 within the mounting cavity 100 avoids obstructing the mating end 101; that is, a channel or space is reserved for the mating end 101 in the layout of the magnetic element 2, without interfering with the normal operation and assembly of the charging probe 3, thus facilitating the integration of the magnetic attraction function with the charging structure.

[0055] like Figure 1 As shown, at least part of the charging probe 3 is disposed in the mounting cavity 100, with one end penetrating the docking end 101 and extending to the side of the mounting cavity 100 away from the opening. It is electrically connected to the circuit board 5 of the equipment by means of welding, crimping, etc., so as to realize the introduction and transmission of charging signals, thereby forming the equipment charging circuit.

[0056] More importantly, in this embodiment, the sealing structure 4 is disposed around the outer periphery of each charging probe 3, at least sealing the gap between the charging probe 3 and the docking end 101. The sealing structure 4 forms an effective sealing barrier between the charging probe 3 and the docking end 101, effectively blocking the path of external moisture to penetrate into the device through the probe gaps.

[0057] Understandably, this invention significantly improves the sealing and protection level of the charging port by introducing a local sealing design inside the charging port structure. It can effectively block moisture and prevent key components such as circuit boards and chips from being damaged by corrosion, short circuits, etc., thereby enhancing the service life and safety of the equipment.

[0058] Furthermore, in an alternative embodiment, the sealing structure 4 can extend to the connection area between the charging probe 3 and the circuit board 5, i.e., the side of the carrier body 1 facing away from the outlet, thereby further expanding the sealing protection range and improving the protection integrity of the entire charging path.

[0059] In one embodiment, the magnetic element 2 is configured as a ring structure, and the mating end 101 is configured as a boss protruding from the bottom of the mounting cavity 100 toward the corresponding opening, with the magnetic element 2 sleeved on the outside of the boss.

[0060] Since the magnetic element 2 is ring-shaped, the empty part in it can avoid interfering with the arrangement of the charging probe 3, and at the same time, the magnetic force is evenly distributed in a ring around the boss, which further improves the stability and reliability of the magnetic attraction between the charging port and the device.

[0061] Through the structural design in this embodiment, the magnetic element 2 can be nested around the boss in the mounting cavity 100 without affecting the function of the charging docking structure, thus achieving structural integration and minimizing the space occupied.

[0062] Optionally, in other embodiments, an insulating layer is provided on the outer periphery of the magnetic element 2, which can effectively prevent electrical connection between the magnetic element 2 and adjacent metal structures or conductive parts, and avoid potential short circuits or other current problems.

[0063] Specifically, the insulating layer can be formed by spraying insulating material onto the outside of the magnetic element 2, or by fixing the insulating material to the outside of the magnetic element 2 through a wrapping and bonding method. In this embodiment, the forming method is not specifically limited, as long as it is ensured that the insulating layer can provide reliable electrical isolation without affecting the magnetic attraction effect.

[0064] In one embodiment, a limiting portion 31 is provided on the peripheral wall of the charging probe 3. The limiting portion 31 protrudes outward in the radial direction to form a ring-shaped structure similar to a flange or shoulder.

[0065] Based on the above, the docking end 101 is configured as a boss within the supporting body 1. The boss has a mounting hole 1010 extending through its height direction for the charging probe 3 to pass through. When the charging probe 3 is inserted into the mounting hole 1010 on the boss, the limiting part 31 will eventually abut against the outer surface of the boss, restricting the charging probe 3 from going any further. This controls the installation depth of the charging probe 3, preventing it from being too deep or too shallow, and ensuring the contact stability between the end face of the charging probe 3 and the corresponding device end.

[0066] Meanwhile, the sealing structure 4 mentioned above closes the gap between the limiting part 31 and the boss, achieving a reliable seal at this position and effectively preventing external impurities such as liquid, water vapor, and dust from seeping into the equipment from the assembly gap between the charging probe 3 and the boss, thereby further ensuring the safety of the internal electrical components.

[0067] Optionally, the shape of the limiting part 31 can be set to a circular flange, a trapezoidal structure, or other forms according to application requirements. It can also be equipped with a positioning groove or other matching structure in conjunction with the sealing structure 4 to provide limiting and positioning effects.

[0068] In one embodiment, the sealing structure 4 includes a first sealing structure 41. See the appendix to the specification. Figure 1 and Figure 2 Specifically, the magnetic element 2, the docking end 101 and the charging probe 3 together form a first space 60 within the same mounting cavity 100. The first sealing structure 41 is disposed within the first space 60. The first sealing structure 41 is generally made of a material with deformation and sealing capabilities, so that it fits tightly against the outer structure of the magnetic element 2, the docking end 101 and the charging probe 3, thereby achieving synchronous sealing of multiple gaps.

[0069] It is worth mentioning that, in this embodiment, by arranging the first sealing structure 41 in the first space 60, not only is the gap between the magnetic element 2 and the charging probe 3 sealed, but the gap between the charging probe 3 and the docking end 101 is also covered and sealed. Compared with setting multiple sealing components separately, this structure achieves overall sealing of key gap areas through the integrated arrangement of the first sealing structure 41, effectively improving the stability and anti-aging ability of the first sealing structure 41, and reducing the sealing risks caused by the splicing of multiple structures.

[0070] With the above-described design, this embodiment can more effectively address the problem of external moisture, humidity, or dust entering the device through the charging port. The first sealing structure 41 within the first space 60 ensures that multiple critical gaps in the charging area are simultaneously covered and protected at the structural source, preventing partial sealing omissions or failures and significantly enhancing the protection capability of the device's charging port.

[0071] More specifically, and understandably, the first sealing structure 41 seals the gap between the magnetic element 2 and the charging probe 3. An unavoidable structural gap exists between the magnetic element 2 and the charging probe 3. Since this gap is a key part of the magnetic and probe structure design, if it is not sealed, impurities may adhere to the magnetic surface of the charging probe 3 or the magnetic element 2, causing poor electrical contact or reduced attraction. By setting the first sealing structure 41, an effective physical barrier is formed, preventing the deposition and intrusion of dust, fine sand, and other particles, thereby extending the service life of the magnetic structure and the charging probe 3.

[0072] On the other hand, the first sealing structure 41 can also reduce the possibility of component loosening or displacement caused by vibration or impact by sealing the gap between the magnetic attraction element 2 and the charging probe 3, thereby improving the durability and reliability of the device.

[0073] In one embodiment, the first sealing structure 41 in the above embodiment can be formed in at least one of the following forms.

[0074] In the first embodiment, the first sealing structure 41 includes a first adhesive layer disposed within the first space 60. The first adhesive layer is formed by injecting and curing an adhesive into the first space 60. For example, a liquid sealing adhesive material, such as epoxy resin or silicone rubber, is used, possessing good adhesion and protective properties. After injection, it is cured by methods such as room temperature curing, heat curing, or ultraviolet light curing, thereby forming a sealing layer within the first space 60 that tightly adheres to the structural gap between the magnetic element 2, the charging probe 3, and the mating end 101.

[0075] Understandably, the first method can achieve good coverage, thus enabling high-precision sealing coverage for complex or tiny structural gaps in the charging port structure, making it suitable for charging module scenarios with compact structures and high sealing requirements.

[0076] In the second embodiment, the first sealing structure 41 includes a first elastic sealing element disposed within the first space 60. The first elastic sealing element can be a sealing ring, sealing strip, or even a sealing gasket, and its material is an elastic material with good resilience and protective properties. (Not shown in the accompanying drawings.) In practical applications, the first elastic sealing element is directly embedded between the magnetic element 2 and the charging probe 3, and between the charging probe 3 and the mating end 101 (the mating end 101 can be provided with a corresponding sealing groove). During assembly, the first elastic sealing element is compressed and deformed, thereby filling the corresponding gaps.

[0077] The second configuration described above facilitates maintenance and replacement, making it suitable for small-batch production or design scenarios requiring adjustments to the sealing structure 4. In summary, the implementation method of the first sealing structure 41 can be flexibly selected based on specific design requirements, production conditions, and application scenarios.

[0078] In one embodiment, one side of the first sealing structure 41 is connected to the bottom of the mounting cavity 100, and the other side extends along the depth direction of the mounting cavity 100 toward the opening side of the mounting cavity 100 to a preset position. That is, the first sealing structure 41 is mainly arranged in the lower region of the entire sealing structure 4, and its upper region can reserve space for other structures or functional components (such as auxiliary sealing structures, support and positioning components, etc.) to avoid structural interference or overfilling affecting assembly efficiency.

[0079] Specifically, the "preset position" can be determined by comprehensively considering factors such as the depth of the mounting cavity 100, the mounting height of the magnetic element 2, and the protrusion height of the charging probe 3. For example, when the magnetic element 2 is relatively high, the first sealing structure 41 can extend upwards more to ensure that it covers the gap area between the magnetic element 2 and the charging probe 3; while when the charging probe 3 is relatively short, the extension height of the first sealing structure 41 can be reduced accordingly to ensure that it does not interfere with the flatness of the magnetic surface.

[0080] By adopting the above structural configuration, the first sealing structure 41 can effectively seal the area between the magnetic element 2 and the charging probe 3, while also having good structural adaptability and spatial coordination, avoiding structural redundancy, increased assembly difficulty, or functional interference caused by improper arrangement of sealing materials.

[0081] In addition, this structural design allows the first sealing structure 41 to further cooperate with other upper protective structures to form a layered sealing structural protection system, thereby improving the stability, stress resistance and long-term weather resistance of the overall sealing structure 4.

[0082] In one embodiment, based on the above embodiments, such as Figure 3 As shown, the supporting body 1 has at least two mounting cavities 100, and each mounting cavity 100 has at least one docking end 101 for electrical connection with the corresponding charging probe 3. At the same time, each mounting cavity 100 is provided with at least one magnetic attraction element 2 to assist in magnetic docking and physical positioning.

[0083] It is understood that by setting multiple mounting cavities 100 in this embodiment, and configuring independent docking ends 101 and magnetic elements 2 in each mounting cavity 100, the overall balance and stability of magnetic docking can be improved, and the problem of eccentric connection or poor contact caused by a single magnetic position can be avoided.

[0084] Generally, two mounting cavities 100 are provided, corresponding to the charging setup of most devices on the market. The two mounting cavities 100 correspond to the charging contacts at both ends or sides of the device, as shown in the figure. The two mounting cavities 100 are symmetrically distributed on the left and right sides of the charging port structure, with their openings facing the same direction (upward), and each is equipped with its own charging probe 3 and magnetic attraction element 2. The mounting cavities 100 can also be arranged in a staggered or surrounding manner, depending on the size, structure, or functional requirements of the device, to achieve higher space utilization.

[0085] Furthermore, the magnetic element 2 in each mounting cavity 100 can be individually set with magnetic pole direction, magnetic attraction strength, and magnetic pole, etc., to adapt to the metal parts arrangement and magnetic field distribution of the corresponding device end, thereby ensuring the overall adsorption balance when multi-point magnetic attraction is combined, and avoiding offset or shaking due to uneven attraction force.

[0086] Optionally, taking the configuration in the attached figure as an example, the magnetic elements 2 in the two mounting cavities 100 are magnets with different magnetic poles, and the magnetic part of the external charging device is also provided with corresponding magnets with different magnetic poles, thus forming a foolproof design when docking at the charging port.

[0087] Understandably, in the corresponding charging probe 3, one probe corresponds to the positive terminal of the charging circuit, and the other probe corresponds to the negative terminal of the charging circuit. When the charging port is connected to an external charging device, the opposite poles of the magnets attract each other, ensuring that the two can be connected quickly and stably. At the same time, the positive and negative poles can also be connected correctly, avoiding charging failure or device damage due to incorrect polarity. If the connection direction is incorrect, the like poles of the magnets will repel each other, thereby preventing incorrect connection.

[0088] In one embodiment, based on the above, the sealing structure 4 further includes a second sealing structure 42, which is disposed between different charging probes 3 to prevent the formation of conductive paths between the charging probes 3 in different mounting cavities 100.

[0089] It should be noted that in actual use, especially when the charging port structure has multiple mounting cavities 100 and each mounting cavity 100 corresponds to a charging probe 3, if these probes are not effectively isolated or electrically disconnected in structure, accidental conduction may occur between the charging probes 3 due to moisture infiltration, dust deposition, intrusion of metal foreign objects, structural loosening, etc., which may cause short circuits, equipment failures, and other problems. In severe cases, it may even endanger the electrical safety and service life of the equipment.

[0090] In this embodiment, a second sealing structure 42 is disposed between different charging probes 3, surrounding the outer periphery of the charging probes 3, and filling or isolating the space between the charging probes 3, ensuring that there is no gap between the charging probes 3 and no gap for electrical connection.

[0091] On the other hand, when moisture enters the equipment, electrolytic corrosion may occur between different charging probes 3, leading to probe damage or poor contact. The second sealing structure 42 prevents moisture from forming an electrolytic environment between the charging probes 3 by isolating the space between them, thereby protecting the integrity and conductivity of the charging probes 3.

[0092] Specifically, as shown in the figure, the second sealing structure 42 is located on the side of the supporting body 1 away from the bottom of the mounting cavity 100, and is used to seal the opening of the mounting cavity 100 to prevent external moisture and impurities from entering the interior of the mounting cavity 100.

[0093] Based on the above-mentioned settings, there is a certain reserved space above the first sealing structure 41, providing a location for the second sealing structure 42; thus, by combining the first sealing structure 41 and the second sealing structure 42, a multi-layered protection system is formed, which can prevent moisture from entering the equipment and ensure electrical isolation between the charging probes 3.

[0094] In one embodiment, the second sealing structure 42 may have the following specific structural form:

[0095] In the first form, the second sealing structure 42 includes a second adhesive layer, which is formed by injecting adhesive material between the charging probes 3 in different mounting cavities 100. The adhesive is cured naturally or by heating after injection, and finally forms an insulating and sealed structure between the charging probes 3.

[0096] Alternatively, the colloidal material can be an electrical encapsulation material with good insulation, high and low temperature resistance, damp heat resistance and aging resistance, such as epoxy resin, silicone, polyurethane, etc., which can effectively isolate potential conductive paths between conductive probes and prevent short circuits, false triggering and other problems caused by the intervention of media such as condensation, salt spray, dust or conductive particles.

[0097] In the second form, the second sealing structure 42 may include a second elastic sealing element, which is an independently set flexible structural element that surrounds the outer periphery of the corresponding charging probe 3 to achieve the effect of physical isolation and insulating encapsulation between the charging probes 3.

[0098] Alternatively, the elastic seal can be made of silicone rubber, thermoplastic elastomer or similar materials, which have good compression resilience, wear resistance and electrical insulation, and are easy to maintain and replace. They are suitable for modular or detachable product structures.

[0099] In one embodiment, the first sealing structure 41 and the second sealing structure 42 can be formed separately or integrally. Separate forming can optimize the material and form of the two sealing structures to meet different design requirements, while integral forming simplifies the production process and improves the overall reliability of the structure.

[0100] In a preferred embodiment, both the first sealing structure 41 and the second sealing structure 42 are formed by injection molding and are arranged sequentially in a bottom-up encapsulation order.

[0101] Specifically, the first sealing structure 41 is disposed in the bottom area of ​​the mounting cavity 100 and is formed by injection of adhesive to seal the gap between the charging probe 3 and the docking end 101, as well as the gap between the charging probe 3 and the magnetic element 2, thereby constructing a first sealing barrier in the area near the circuit board 5 to prevent moisture or impurity particles from seeping into the core electronic component area inside the device through the gap between the charging probe 3 and the carrier body 1.

[0102] After the first sealing structure 41 is formed, a second sealing structure 42 is further provided above it. The second sealing structure 42 is used to seal the structural gaps between different charging probes 3, preventing the formation of conductive paths between probes in multiple mounting cavities 100, and achieving electrical isolation between each charging path. By forming a sealing and protective strip step by step through this double-layer injection structure, the reliability and safety of the charging port are significantly improved.

[0103] The first sealing structure 41 and the second sealing structure 42 are formed by adhesive injection, which facilitates automated potting during manufacturing and improves production efficiency. Of course, in other embodiments, the first sealing structure 41 and the second sealing structure 42 can also be respectively configured as elastic seals, or a combination of an adhesive injection structure and an elastic seal can be used. For example, the first sealing structure 41 uses an adhesive layer to provide an integral seal at the bottom, and the second sealing structure 42 uses a replaceable elastic sealing ring for easy subsequent maintenance.

[0104] In one embodiment, in the support body 1, a partition 11 is provided between every two mounting cavities 100, the partition 11 being used to relatively isolate the magnetic elements 2 within the connected mounting cavities 100.

[0105] With the above structural setup, in the charging port structure, multiple mounting cavities 100 are arranged side by side in the same supporting body 1. The partition 11 serves as a spacer and support unit between the structures, which can effectively prevent mutual interference or magnetic field superposition between the magnetic elements 2, and avoid problems such as inaccurate charging docking, insufficient magnetic attraction force or bias due to disordered magnetic force direction and intersecting magnetic lines of force, thereby significantly improving the positioning stability of the magnetic connection and the user experience.

[0106] In addition, the partition 11 itself can also serve as an installation reference surface to assist in the positioning, limiting and fixing of the magnetic elements 2 inside the mounting cavity 100, reduce assembly errors and further improve the yield and structural strength of finished products.

[0107] In specific implementation, the partition 11 can be integrally injection molded from the same material as the main body 1, or it can be inserted as an independent insert between the corresponding mounting cavities 100. It can also be designed as a straight line, arc or grid structure according to the number and spatial arrangement of the mounting cavities 100, to adapt to the shape layout and magnetic structure of different types of wearable devices.

[0108] Please refer to the instruction manual. Figure 3 The partition 11 is erected on the bottom wall of the supporting body 1 to form a stable vertical separation between adjacent mounting cavities 100. It can be understood that this vertical structure not only provides a clear spatial boundary between each mounting cavity 100, but also helps to define the mounting area of ​​each magnetic element 2, avoiding the magnetic docking effect from being affected by structural displacement or magnetic interference during charging.

[0109] In one embodiment, a further protruding partition 110 is provided on the side of the partition 11 facing away from the bottom wall of the supporting body 1. The partition 110 is formed on the top of the partition 11 and is a raised structural segment, which is located between adjacent mounting cavities 100 and is used to form an insulating mating interface with the second sealing structure 42.

[0110] Specifically, when the second sealing structure 42 is formed by adhesive injection, the partition 110 can form a relative interlocking relationship with the corresponding second adhesive layer after the adhesive is injected and cured. This provides lateral restraint to the second adhesive layer, preventing positional displacement of the cured second adhesive layer and ensuring the reliability of the electrical isolation. Simultaneously, this structure also improves the controllability of the adhesive injection process, facilitating the limitation of the injection area and adhesive volume, and preventing seal failure due to excessive or insufficient adhesive injection.

[0111] In the embodiment where the second sealing structure 42 is an elastic seal, the partition 110 can serve as a pressing and limiting surface or a bonding auxiliary surface for the elastic seal. During the assembly process of the elastic seal, it plays a preliminary positioning and blocking role, enabling the seal to form a stable bonding interface between the charging probes 3 and improving electrical insulation and moisture isolation performance.

[0112] In addition, the partition 110 may not directly engage with the sealing structure 4, but can serve as a simple structural partition to completely isolate adjacent mounting cavities 100 in terms of structure, thereby realizing modular management of the magnetic element 2, probe structure and sealing structure 4, which is beneficial to the design and maintenance of the overall module.

[0113] In actual design, the partition 110 can be an integrally formed rib-like structure or a flange structure.

[0114] In one embodiment, such as Figure 3 and Figure 4 As shown, the main body of the carrier body 1 without the docking end 101 is set as a closed frame structure. That is to say, except for the area where the docking end 101 is set (the charging probe 3 needs to pass through), the rest of the carrier body 1 is a closed structure, which is used to effectively block the intrusion of external moisture, dust and other impurity particles, and enhance the overall sealing and protection performance of the charging port.

[0115] Thus, the sealing structure 4 and the supporting body 1 together structurally constitute a sealed barrier for the charging port structure. Specifically, the sealing structure 4 is mainly arranged around the outer periphery of the charging probe 3. Therefore, the design of the sealing structure 4 can be very focused, mainly sealing the micro-gap that may be formed between the protruding part of the charging probe 3 and the supporting body 1, and achieving electrical isolation between the charging probes 3. Since the body of the supporting body 1 is a closed frame, it already has strong waterproof and dustproof performance. Therefore, the technical solution provided in this application no longer relies on the all-round sealing of the entire shell, but instead focuses on sealing the core weak links of the charging path.

[0116] Compared to traditional protection methods that require a completely sealed outer casing, this solution achieves a waterproof rating while reducing structural complexity by centrally sealing the relevant structures of the charging probe 3, combined with its own enclosed frame design. In practical implementation, the enclosed frame can be formed through methods such as one-piece injection molding, metal stamping, or modular assembly.

[0117] Meanwhile, most of the structural area of ​​the main body 1 is an integrally enclosed component, which simplifies the use of auxiliary materials such as seals and colloids, which helps to reduce manufacturing costs and reduce maintenance needs caused by seal aging during long-term use.

[0118] It should also be noted that, in practical applications, in order to meet the needs of mechanical connection, structural fixation or functional extension between the load-bearing body 1 and other structural components, a small number of holes or through holes for structural assembly can still be pre-set in some areas of the load-bearing body 1.

[0119] It should be emphasized that even though the support body 1 is provided with the above-mentioned holes for structural assembly, such holes are usually located in non-critical functional areas and can be partially sealed by sealing means such as sealing rings, sealing gaskets, and colloid sealing. From the overall structure of the support body 1, it is still closed and will not easily affect the sealing performance of the charging probe 3. Therefore, the charging port structure of this application can still ensure excellent sealing and waterproof performance.

[0120] In one embodiment, such as Figure 2 As shown, the charging port structure also includes a top cover 7, which is connected to the supporting body 1 from the opening side of the mounting cavity 100. Specifically, the top cover 7 can be a cover structure, which is fixedly connected to the supporting body 1 by means of buckles, threads, ultrasonic welding, adhesive or screws, etc., and works with the sealing structure 4 to form multiple layers of protection and sealing for the internal structure. At the same time, the top cover 7 can also play a role in preventing dust, preventing foreign object intrusion, and preventing liquid splashing.

[0121] When the second sealing structure 42 is formed by injection, the top cover 7 can be directly bonded to the supporting body 1 through the second sealing structure 42. At this time, the second sealing structure 42 not only achieves the waterproof sealing function, but also serves to connect the top cover 7 and the supporting body 1.

[0122] An adapter hole 70 is further provided on the top cover 7 for the charging probe 3 to pass through and be positioned during assembly. The diameter of the adapter hole 70 should be designed according to the outer diameter of the charging probe 3, and can be set to an interference fit, clearance fit, or sliding fit to cooperate with the charging probe 3, thereby guiding and limiting the charging probe 3 during the assembly process, improving the assembly accuracy and stability of the charging probe 3.

[0123] Understandably, by setting the top cover 7 and the adapter hole 70 in this embodiment, not only can a physical support point be provided at the front end of the charging probe 3 to prevent the charging probe 3 from being misaligned or shaken due to force, but it can also form a double sealing protection with the internal sealing structure 4, which can significantly improve the environmental adaptability and service life of the entire charging port structure.

[0124] In practical implementation, the top cover 7 can be made of transparent, semi-transparent, or opaque material, and can also be designed to be the same color as the device housing or have an integrated shape to meet the requirements of aesthetics and process consistency. It should be noted that in some cases, the top cover 7 can be the housing of the device itself (such as a smartwatch or smart bracelet), that is, it is also feasible to set the adapter hole 70, connection structure, etc. on the housing of the device itself to realize the connection between the housing and the supporting body 1.

[0125] Meanwhile, the number, shape, and arrangement of the adapter holes 70 can be set according to the number and spacing of the charging probes 3, such as multiple hole arrays, circular through holes, elliptical elongated holes, etc.

[0126] Furthermore, the inner wall of the adapter hole 70 can be provided with a flexible sealing ring or filled with a small amount of sealing colloid to further improve the sealing performance of the adapter hole 70 and prevent external liquid from seeping down along the charging probe 3.

[0127] In one embodiment, based on the above embodiment, at least a portion of the adapter hole 70 is configured as a tapered tube section 701 with a diameter that gradually decreases along the first direction. The large-diameter end of the tapered tube section 701 is positioned close to the support body 1 to form a guide structure on the relative assembly path of the top cover 7 and the charging probe 3, thereby assisting the charging probe 3 in achieving accurate insertion and assembly positioning.

[0128] Understandably, the "first direction" refers to the insertion direction of the charging probe 3 during the assembly process relative to the top cover 7, as indicated by the arrow markings in the accompanying drawings. The large-diameter end of the tapered tube section 701 faces the supporting body 1, meaning that when the charging probe 3 is gradually inserted into the adapter hole 70 of the top cover 7, its front end can first enter the large-diameter end of the tapered tube section 701, and then gradually transition to the small-diameter end and complete positioning under the guidance of the inwardly tapering inner wall, effectively avoiding problems such as deflection, jamming, or damage during the insertion of the charging probe 3.

[0129] Based on the design in this embodiment, namely the design of the tapered tube section 701, in actual production, it can improve the tolerance adaptability of automated assembly, reduce the risk of assembly misalignment, and improve assembly efficiency. Optionally, the tapered tube section 701 can be set in the form of tapering, curved tapering, or step reduction, etc., and its taper size can be determined according to factors such as the diameter of the charging probe 3, the insertion depth, and the mating structure. In this embodiment, its specific value is not limited.

[0130] In one embodiment, according to another aspect of this application, this application further provides a smartwatch, the smartwatch including the charging port structure as described above.

[0131] This charging port structure, through its integrated support body 1, magnetic element 2, charging probe 3, and sealing structure 4, can effectively improve the waterproof, dustproof, and electrical insulation performance of the smartwatch's charging port while ensuring charging reliability.

[0132] Please refer to the instruction manual. Figure 5 The attached diagram does not show the overall structure of the smartwatch. The charging port structure is part of the overall structure of the smartwatch, and the charger that works with it is located above it. By combining the charging port structure in this application with the structure of the smartwatch, the charging reliability and lifespan of the charging port can be effectively improved.

[0133] Furthermore, a corresponding positioning groove structure can be set on the top cover 7 in the charging port structure to adapt to the contour of the charging head, so that the charging head can fit into the top cover 7 during charging, thereby improving the relative stability between the charging head and the smartwatch during charging.

[0134] In contrast, in one embodiment, according to another aspect of this application, this application further provides a magnetic charger, which includes the charging port structure described above, to realize the magnetic connection and electrical connection between the magnetic charger and the corresponding device, thereby enabling power supply to the corresponding device.

[0135] In general, the charging port structure proposed in this invention is not only applicable to smart devices that require power reception (such as smartwatches, wristbands, wireless earphones, etc.), but also to power supply devices that provide power output (such as magnetic chargers, portable charging docks, etc.), enabling reliable application in the field of magnetic charging structures.

[0136] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred 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.
