[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0036] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this utility model, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0038] When charging a mobile phone, in order to avoid the data cable getting in the way, users are used to stacking the power bank and the phone and holding them with one hand at the same time. However, the increase in capacity has led to a corresponding increase in the size of the power bank, resulting in a poor experience in holding and operating it.

[0039] Wearable power banks have been designed in some related technologies, which free up users' hands and improve the user experience. However, in order to ensure the wearing experience, wearable power banks often have to sacrifice the capacity of the power bank, making it difficult to meet the needs of frequent charging.

[0040] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0041] Reference Figure 1 , Figure 2 , Figure 3According to an embodiment of the present invention, a wearable mobile power supply is provided, including a wristband 1, a control board 2, a battery 3, and a cover plate 4. The wristband 1 has an internal cavity and includes a partition 101 that divides the cavity into a battery compartment 102 and a board compartment 103 that are interconnected. The wristband 1 also has a battery swapping hole and a charging hole 104. The battery swapping hole is connected to the battery compartment 102, and the charging hole 104 is connected to the board compartment 103. The control board 2 includes a first plate body 201 and a charging interface 202. The first plate body 201 is disposed in the board compartment 103, and the charging interface 202 is disposed on the first plate body 201. The positions of the charging interface 202 and the charging hole 104 correspond to each other. The battery 3 can be detachably disposed in the battery compartment 102 through the battery swapping hole to electrically connect to the control board 2. The cover plate 4 is detachably disposed in the battery swapping hole.

[0042] When in use, the wearable power bank is worn on the user's wrist via the wristband 1, and the charging port 202 is connected to the device via a data cable, thus avoiding the inconvenience of holding the wearable power bank while in use.

[0043] Furthermore, the wearable power bank uses removable and replaceable batteries 3. When in use, one battery 3 is placed in the battery compartment 102, and the other batteries 3 are carried as spares. This ensures that the wearable power bank has a large capacity while also keeping the wristband 1 lightweight, making the user's wearing experience more comfortable.

[0044] For example, travelers and outdoor enthusiasts can carry multiple spare batteries 3 in their backpacks. While walking, the user holds their phone with the hand wearing the wearable power bank, bringing the charging port 202 close to the phone. This allows for a shorter charging cable to connect the phone and the power bank, enabling charging without interfering with walking or using the phone. Users can easily extend battery life by simply removing and replacing batteries 3, avoiding frequent charging and ensuring uninterrupted power for their devices in outdoor environments.

[0045] In some embodiments, refer to Figure 4 The charging interface 202 uses two Type-C interfaces. Alternatively, in some other embodiments, the charging interface 202 may use other types of interfaces (such as USB interfaces or Lightning interfaces). The number of charging interfaces 202 may be one or more, and this utility model does not limit this.

[0046] Furthermore, in some embodiments, the wearable power bank can also be equipped with near-field wireless charging, thereby eliminating the need for charging cables in some cases and further improving ease of use.

[0047] In some embodiments, the battery 3 may use a standard specification battery 3, thereby improving the compatibility of the wearable power bank; or, in other embodiments, the battery 3 may use a custom specification curved battery 3, thereby better adapting to the shape of the wrist, suitable for using a larger battery 3 (e.g., a battery 3 with a capacity of up to 10000mAh), increasing the capacity of the battery 3.

[0048] For example, refer to Figure 2 In some embodiments, the battery 3 uses a square battery 3 with a size specification of 105060. The battery 3 has gold fingers, which are electrically connected to the control board 2, thereby facilitating the replacement of the battery 3. The gold fingers have a large surface area, which can also improve the current carrying capacity and ensure the power supply efficiency of the battery 3.

[0049] Battery 3 can be inserted into battery compartment 102 in different ways. In some embodiments, refer to Figure 2 and Figure 4 The wristband 1 has an axial direction, and the battery swapping hole is located at one end of the wristband 1 in the axial direction; the control board 2 also includes a second board 203, which is located in the battery compartment 102 and at the other end of the wristband 1 in the axial direction. The battery 3 can contact the second board 203, and the second board 203 and the first board 201 are electrically connected.

[0050] Battery 3 is inserted into battery compartment 102 along the axial direction. Cover plate 4 closes battery compartment 102 and presses battery 3 against second plate 203, making contact between battery 3 and second plate 203. This establishes an electrical connection between battery 3 and control board 2, allowing power to be output to charging interface 202 or charged from charging interface 202. Cover plate 4 also secures battery 3 within battery compartment 102, ensuring stable contact between battery 3 and second plate 203. After removing cover plate 4, battery 3 is unlocked and can be removed from battery compartment 102.

[0051] In some embodiments, the control board 2 further includes a display device 204, and the wristband 1 has a display window 105, with the display device 204 and the display window 105 positioned correspondingly. The display device 204 can display information such as the power level and charging / discharging status of the wearable power bank, so that the user can accurately perceive the status of the battery 3 during use.

[0052] For example, refer to Figure 4 In some embodiments, the display device 204 is disposed on the second plate 203, facing the end of the wristband 1 away from the power exchange hole in the axial direction. The display device 204 can use LEDs, with multiple LEDs arranged side by side on the second plate 203, indicating the power level and charging / discharging status of the wearable power bank through the brightness and color of the LEDs. Alternatively, besides... Figure 4In addition to the LEDs shown, the display device 204 can also be a display screen, thereby providing richer display effects, enhancing the user experience, and helping users to rationally plan their power consumption needs.

[0053] Other possible design methods for the display device 204 can be found in the relevant existing technologies, and will not be elaborated here.

[0054] Furthermore, in addition to being mounted on the second plate 203, the display device 204 can also be mounted on other locations on the control board 2, such as on the first plate 201 or other additional plates, as long as it corresponds to the position of the display window 105 so that the user can observe the display status of the display device 204 from the display window 105. This utility model does not impose any restrictions on this.

[0055] In some embodiments, the control board 2 also includes gallium nitride (GaN) power devices. Using GaN power devices for energy transfer helps improve transmission efficiency, enabling fast charging. GaN power devices also reduce current-induced heat generation, thus improving the wearing experience.

[0056] It is understandable that, in addition to the display device 204, gallium nitride power device, and charging interface 202, the control board 2 will also have other components (not shown in the figure), and these components will be connected together through circuit diagrams. The various components required for the control board 2 can be found in relevant existing technologies, and will not be described in detail here.

[0057] The components and circuit diagrams in the control board 2 construct the battery management system of the wearable mobile power supply, which manages the charging and discharging process of the battery 3, thereby adapting to the charging protocols of different power devices. Optionally, the battery management system can be optimized (e.g., using the lithium-ion battery constant current constant voltage charging method CCCV in related technologies) to optimize the charging and discharging cycle, reduce power loss, prevent overheating, extend battery life, and ensure the safety of the charging process.

[0058] Preferably, most of the components of the control board 2 are located on the first board body 201 and on the side of the first board body 201 facing away from the battery compartment 102, thereby making full use of the space of the board compartment 103 and separating the components and the battery 3 to avoid mutual interference.

[0059] The various boards in control board 2 can be connected together in different ways. For example, the first board 201 and the second board 203 can be rigid boards, which are connected to each other via connectors; or, the second board 203 can be a flexible printed circuit board (FPC), with one end of the second board 203 soldered to the first board 201 via pins, and the second board 203 is bent to change its orientation and extend into the battery compartment 102; or, for another example, the first board 201 and the second board 203 can be rigid boards, and control board 2 also includes a third board as a flexible board, with both ends of the third board connected to the first board 201 and the second board 203 respectively, thereby realizing the connection and conduction of the circuit. The specific shape and layout of control board 2 can be flexibly determined according to actual needs and the space of the accommodating cavity, and will not be elaborated here.

[0060] In some embodiments, refer to Figure 5 The cover plate 4 includes a cover body 401 and a lifting part 402. The shape of the cover body 401 matches the shape of the battery swapping hole. A positioning protrusion 403 is formed on the outer periphery of the cover body 401. A positioning groove that matches the positioning protrusion 403 is provided on the wall of the battery swapping hole. The lifting part 402 is connected to one end of the cover body 401.

[0061] The positioning protrusion 403 and the positioning groove engage with each other, thereby securing the cover plate 4 firmly to the wristband 1 and ensuring that the battery 3 and the second plate 203 are in close contact. When it is necessary to replace the battery 3, the cover plate 4 can be opened easily by applying force through the lifting part 402 and leveraging the leverage effect to release the battery 3 from the fixation.

[0062] It is understandable that for travelers and outdoor sports enthusiasts, as well as in areas with unstable power supply, wearable power banks may have difficulty charging in a timely manner. In order to further improve the battery life of wearable power banks, in some embodiments, wearable power banks also include solar panels 5, which are attached to the outer periphery of the wristband 1.

[0063] When the user is outdoors, sunlight shines on the solar panel 5, which can continuously charge the battery 3 in the battery compartment 102 during the user's daily activities, replenish the battery 3, improve the battery life of the wearable power bank, and eliminate the user's battery anxiety.

[0064] Specifically, refer to Figure 6 In order to make the solar panel 5 and the control board 2 electrically connected, in some embodiments, the housing is also provided with a wire hole 108, which connects to the panel compartment 103, and the solar panel 5 is connected to the control board 2 through the wire hole 108.

[0065] In some embodiments, the wearable power bank further includes a heat sink 6, which is disposed on the wristband 1 and thermally connected to the wall of the battery compartment 102. The heat sink 6 helps absorb the heat generated by the battery 3 so as to transfer the heat outward, thereby preventing the battery 3 from overheating and ensuring the safety and comfort of the wearable power bank.

[0066] For example, refer to Figure 2 In some embodiments, the heat sink 6 is a heat-conducting sheet, which is attached to the outer periphery of the wristband 1 and stacked with the solar panel 5. In this case, the heat-conducting sheet can be made of metal or other materials with high thermal conductivity. The heat-conducting sheet transfers heat to the solar panel 5, and the surface area of ​​the solar panel 5 dissipates the heat into the environment.

[0067] For example, in some embodiments, the heat sink 6 can also use a miniature cooling fan, with heat dissipation holes on the housing connecting the plate compartment 103 and / or the battery compartment 102. The cooling fan generates forced convection within the housing cavity, improving the heat dissipation effect. Furthermore, the cooling fan can be used in conjunction with a semiconductor cooling chip to further improve the heat dissipation effect of the wearable power bank.

[0068] In some embodiments, the bracelet 1 is made of carbon fiber composite material. Using carbon fiber composite material can reduce the weight of the bracelet 1, thereby contributing to the lightweight design of the wearable power bank and further improving the wearing experience.

[0069] Preferably, the wristband 1 can be made of carbon fiber composite material with high thermal conductivity, thereby improving the heat dissipation capacity of the wearable power bank while reducing its weight.

[0070] Alternatively, the bracelet 1 can also be made of low-density materials such as polymer materials, which can balance high strength and lightweight, ensuring the durability and long-term use of the wearable power bank.

[0071] Other materials that can be used for the wristband 1 can be referenced in the material selection of wearable devices in related technologies. The wristband 1 can be made of a single material or a combination of multiple materials, which will not be elaborated here.

[0072] In some embodiments, the wristband 1 includes a ring body 106 and two wrist buckles 107, which are respectively disposed on both sides of the ring body 106. The wearable power bank is fastened to the user's wrist via the wrist buckles 107.

[0073] For example, refer to Figure 1 The main body 106 and the two wrist buckles 107 can be designed with a smooth transition, so that the overall shape of the wearable power bank is coordinated and beautiful, and it can also be used as an accessory, taking into account both practicality and aesthetics.

[0074] In addition, Figure 1 In the illustrated embodiment, the two wrist buckles 107 are not connected together, and there is an opening between the two wrist buckles 107. The opening is opened by the deformation ability of the wrist buckles 107 themselves, so that the bracelet 1 and the wrist are fastened. In some other embodiments, the bracelet 1 may also be composed of a ring body 106 and two wristbands. The wristbands have better deformability and can be connected to each other to better adapt to the wrist size changes of different users.

[0075] The specific design of the wristband can be referenced from the wearing methods of bracelets and watches in related technologies, and will not be elaborated here.

[0076] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
