Detailed Implementation

[0040] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0042] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows: Example

[0043] Reference Appendix Figure 1 The charging device provided in this application includes a first charging body 1, a second charging body 2, and a third charging body 3; the first end of the second charging body 2 is rotatably connected to the first charging body 1, and the second charging body 2 is connected in series with the first charging body 1; the third charging body 3 is rotatably connected to the second end of the second charging body 2, and the third charging body 3 is provided with a wireless charging component 4, which is connected in series with the second charging body 2; wherein, the first charging body 1 and / or the second charging body 2 are provided with at least one electrical connection port 5; the first charging body 1, the second charging body 2, and the third charging body 3 can rotate relative to each other to form different charging postures.

[0044] Specifically, to address the problems of poor size adaptability, difficulty in holding, poor shape adaptability, and inappropriate fit of existing power banks when used with different mobile terminals, this embodiment provides a charging device comprising three charging bodies. The three charging bodies can rotate relative to each other to form different charging postures to adapt to electronic devices of different sizes and different charging scenarios. At the same time, the third charging body 3 is provided with a wireless charging component 4, and the first charging body 1 and / or the second charging body 2 are provided with an electrical connection port 5, so that the charging device can perform both wired and wireless charging to adapt to different charging scenarios and charging needs.

[0045] The charging device provided in this embodiment can be a portable charging device that can be carried out or placed indoors for charging; the charging objects can be, but are not limited to, mobile phones, tablets, laptops, small speakers, small fans, handheld fans, etc., as long as the device needs short-term charging or portable charging.

[0046] In this embodiment, adjacent charging bodies 1, 2, and 3 are rotatably connected, allowing at least one charging body to rotate approximately 360 degrees relative to the other two. For example, the third charging body 3 can rotate from being attached to the first side surface of the second charging body 2 to being attached to the second side surface opposite to the first side surface of the second charging body 2. Furthermore, in this embodiment, the rotation of the charging body can stop at any angle. This configuration can be achieved through rotating structures such as friction hinges or self-locking shafts, which are easily understood and implemented by those skilled in the art and will not be elaborated upon here. Correspondingly, in this embodiment, the first charging body 1 and the third charging body 3 can be rotated in opposite directions to be attached to the opposite sides of the second charging body 2, achieving stacked storage of the three components. In this embodiment, the first charging body 1, the second charging body 2, and the third charging body 3 can have at least... Figure 3 The fully flat charging posture shown and Figure 12The charging posture shown is such that the three components are stacked in sequence. In order to make the charging device provided in this embodiment adaptable to charging various electronic devices and easy to hold, reduce size difference, and improve shape adaptability and fit, the length of the three charging bodies when fully unfolded can be set to be equal to the width of the laptop. It can be completely equal or approximately equal, for example, 300-315mm. This allows for stacked charging with the laptop without size difference, and can be, but is not limited to, being attached to the C-shell or D-shell. In this embodiment, the width of the three charging bodies in the stacked state can also be set to be equal to the width of the mobile phone. It can be completely equal or approximately equal, for example, 80-85mm. This allows for stacked charging with the mobile phone without size difference and is easy to hold.

[0047] The first charging body 1 may include a first housing 11, and at least one first battery 12 is disposed inside the first housing 11. The first housing 11 is a rigid housing, which provides at least a space for accommodating the first battery 12 and related wiring. The shape of the first housing 11 can be designed and adjusted according to actual needs, and may be, but is not limited to, [specific features]. Figure 1 The rectangle shown can be, but is not limited to, a lithium battery, a lithium polymer battery, etc. The number of first batteries 12 can be designed and adjusted according to actual needs, for example, by referring to the size of the first housing 11 and the capacity of the first battery 12.

[0048] The second charging body 2 may include a second housing 21, which is rotatably connected to the first housing 11. At least one second battery 22 is housed within the second housing 21, and the at least one second battery 22 is connected in series with at least one first battery 12 to form a battery pack. The second housing 21 is a rigid housing, providing space for at least one second battery 22 and related wiring. The shape of the second housing 21 can be designed and adjusted according to actual needs; it may be the same as or different from the first housing 11. The second battery 22 may be, but is not limited to, lithium batteries, lithium polymer batteries, etc. The number of second batteries 22 can be designed and adjusted according to actual needs, for example, by referring to the size of the second housing 21 and the capacity of the second battery 22. In this embodiment, regardless of the number of first batteries 12 and second batteries 22, a battery pack connected in series can be formed. This configuration is easily understood by those skilled in the art and will not be elaborated upon here.

[0049] Accordingly, the charging device in this embodiment may also include a circuit board to cooperate with the battery pack, electrical connection port 5, and wireless charging component 4 for charging and discharging. For example, in this embodiment, a first circuit board 13 may be provided in the first charging body 1 or the second charging body 2. The first circuit board 13 is electrically connected between the electrical connection port 5 and the battery pack. The first circuit board 13 may be provided with a charging and discharging management integrated circuit, etc., to complete the charging and discharging of the electrical connection port 5 and the battery pack. This setting is easily understood by those skilled in the art and will not be elaborated here. It should be noted that the setting position and number of electrical connection ports 5 can be designed and adjusted according to actual needs. For example, electrical connection ports 5 may be provided on the first charging body 1 or the second charging body 2. The electrical connection port 5 may include a charging port and a discharging port. Electrical ports are provided to enable charging devices from the charging device to the electronic device and charging devices from an external power source. Electrical connection ports 5 can be, but are not limited to, USB ports (Type-A, Type-B, Type-C, Mini-USB, Micro-USB), Lightning connectors, DC jacks, etc. In this embodiment, electrical connection ports 5 can also be provided on both the first charging body 1 and the second charging body 2. For example, an electrical connection port 5 can be provided at the end of the first charging body 1 furthest from the second charging body 2, and simultaneously on the side of the second charging body 2 not connected to other charging bodies. This allows for convenient wired charging in different locations to adapt to different charging scenarios. The specific configuration of the electrical connection ports 5 in this configuration is the same as described above and will not be repeated here. (See attached document.) Figure 2 In this embodiment, a first battery 12 can be set in the first charging body 1, and a second battery 22 and a first circuit board 13 can be set in the second charging body 2. This makes efficient use of space and maximizes the number and capacity of batteries. The second battery 22 can be the same as or different from the first battery 12, for example, a 4000mAh lithium battery.

[0050] The wireless charging component 4 can be a structural component that charges using methods such as electromagnetic induction, magnetic resonance coupling, radio waves, laser beam charging, ultrasonic energy transmission, and capacitive coupling. For example, the wireless charging component 4 discharges based on electromagnetic induction, thus it is a transmitting coil structure. The electronic device that works with it for wireless charging needs to have a receiving coil that can work with the transmitting coil. This configuration is easily understood by those skilled in the art and will not be elaborated here. To facilitate the charging and discharging of the wireless charging component 4, a second circuit board 31 can also be provided in this embodiment. The second circuit board 31 can be equipped with a charging and discharging management integrated circuit to complete the charging and discharging management and control of the wireless charging component 4. This configuration is easily understood by those skilled in the art and will not be elaborated here. The second circuit board 31 can be electrically connected to the battery pack to supply power to the wireless charging component 4. The second circuit 31 is electrically connected to the first circuit 13 and works with a common logic controller. Of course, a logic controller can also be set separately on the second circuit 31. This configuration is easily understood by those skilled in the art and will not be elaborated here. It is not difficult to understand that the third charging body 3 may also include a third housing 32. The third housing 32 is a rigid housing, which provides at least a space for the wireless charging component 4, the second circuit board 31 and related wiring. The shape of the third housing 32 can be designed and adjusted according to actual needs. It can be the same as or different from the first housing 11. In this embodiment, the size of the third housing 32 can be designed to be smaller than the first housing 11 and the second housing 21 so that it can be adapted to the size of small electronic devices such as mobile phones.

[0051] As described above, the charging device provided in this application achieves folding and deformation to accommodate different electronic devices and usage scenarios through the continuous arrangement of three charging elements. It also features both wired and wireless charging capabilities, improving the charging capacity and adaptability to electronic devices of different sizes. This solves the problems of poor size adaptability, difficulty in holding, poor shape adaptability, and inappropriate fit of existing power banks when used with different mobile terminals.

[0052] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can be understood as: A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0053] Furthermore, in a specific implementation of the charging device provided in this embodiment, the first charging body 1 and / or the second charging body 2 are provided with a first magnetic attraction part (not shown in the figure); and / or

[0054] A first magnetic attraction part (not shown in the figure) is provided at the rotatable connection between the first charging body 1 and the second charging body 2, and at the rotatable connection between the second charging body 2 and the third charging body 3.

[0055] Understandably, to adapt to different electronic devices, reduce holding time, and improve ease of use, this embodiment can configure the charging device to be magnetically fixed. A first magnetic part can be provided on the charging body. For example, the first magnetic part can be provided individually on the first charging body 1 or the second charging body 2, or simultaneously on both. This allows the first charging body 1 and / or the second charging body 2 to be magnetically fixed to the electronic device being charged, resulting in a larger contact surface for improved stability. Alternatively, the first magnetic part can be provided at other locations instead of on the charging body. For example, the first magnetic part can be provided at the rotational connection between the first charging body 1 and the second charging body 2, or at the rotational connection between the second charging body 2 and the third charging body 3. This avoids large-scale magnetic structures, preventing impact on the battery pack or circuit board and improving safety. Alternatively, the first magnetic part can be provided both on the charging body and at the rotational connection to improve magnetic attraction, expand the magnetic range, and enhance magnetic stability. For example: refer to the attached... Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 10 Appendix Figure 11 When the first charging body 1 and the second charging body 2 are in a parallel and coplanar unfolded state, they can be attracted and fixed to the surface of the electronic device by the first magnetic attraction part. In this state, they can be electrically connected to the electronic device through the electrical connection port 5 for charging. Correspondingly, a metal shell that can be magnetically attracted can be directly used on the electronic device. A metal shell or frame that can be magnetically attracted and can be quickly disassembled can be designed for the electronic device, such as iron, steel, stainless steel, etc. A third magnetic attraction part adapted to the first magnetic attraction part can also be set inside the electronic device shell. It is easy to understand that the first magnetic attraction part can be, but is not limited to, a magnet, a permanent magnet, etc.

[0056] Further, see Appendix Figure 4 Appendix Figure 8 and appendix Figure 9 In the specific implementation of the charging device provided in this embodiment, the third charging body 3 is provided with a second magnetic attraction part (not shown in the figure) around the periphery of the wireless charging component 4.

[0057] It is understandable that, in order to adapt to stable charging of small electronic devices, including but not limited to mobile phones, this embodiment can provide a second magnetic part on the third charging body 3. The second magnetic part can be, but is not limited to, a magnet, a permanent magnet, etc., and can be set on the inner wall of the third housing 32. Specifically, it is set around the periphery of the wireless charging component 4. Since the main functional area of ​​the third charging body 3 is the area corresponding to the wireless charging component 4, it is sufficient to ensure that this area is stably attached to the electronic device. Therefore, the second magnetic part can be set around the periphery of the wireless charging component 4, either intermittently or continuously.

[0058] For this configuration method, please refer to the attached document. Figure 3 and attached Figure 4 When the first charging body 1, the second charging body 2, and the third charging body 3 are parallel to each other and coplanar, i.e., when the charging device is fully unfolded and flat, the third charging body 3 can be adsorbed onto the first electronic device 6, and the first charging body 1 and the second charging body 2 can be adsorbed onto the second electronic device 7. The wireless charging component 4 within the third charging body 3 supplies power to the first electronic device 6, and the electrical connection port 5 supplies power to the second electronic device 7, simultaneously supplying charging operations for both electronic devices. It is easy to understand that the second electronic device 7 can be large enough to be unsuitable for wireless charging, such as a laptop computer, while the first electronic device 6 can be small enough to be suitable for wireless charging, such as a mobile phone or tablet computer. Furthermore, in this embodiment, the third charging body 3 can be set as a square shape that matches the width of the first electronic device 6. This avoids problems such as edge differences, unevenness, and protrusions, regardless of whether the first electronic device 6 is vertically or horizontally aligned with the third charging body 3. Figure 8 and Figure 9 As shown, when the first charging body 1 and the second charging body 2 are stacked, the first electronic device 6 can be in a vertical charging state or a horizontal charging state.

[0059] Furthermore, in the specific implementation of the charging device provided in this embodiment, the thicknesses of the first charging body 1, the second charging body 2, and the third charging body 2 satisfy the same condition.

[0060] Understandably, to improve ease of use, applicability, and applicable scenarios, and to prevent mistakes, the thickness of the three charging elements in this embodiment is set to meet the same conditions. This can be completely identical or approximately identical, for example, 6.5mm. In this configuration, the thickness of the first battery 12 and the second battery 22 can be 5.5mm. The first battery 12 and the second battery 22 remain flat or side-by-side within the casing. When all three elements, or two of them, are in a parallel and coplanar state (i.e., fully unfolded and flat) and are then attached to the electronic device, not only is the fit high, but the flatness of the exposed surfaces is also high, preventing unevenness that could affect the appearance or grip. With all three fully unfolded and flat, there is no need to distinguish between the front and back for attachment and fixation, improving convenience.

[0061] Further, see Appendix Figure 5 and attached Figure 7 In the specific implementation of the charging device provided in this embodiment, the external dimensions of the first charging body 1 and the second charging body 2 meet the same condition; the external dimensions of the third charging body 3 are smaller than the external dimensions of the second charging body 2.

[0062] Understandably, in order to achieve the largest possible battery capacity while meeting the size requirements of small devices like mobile phones, the first charging body 1 and the second charging body 2 can have the same or approximately the same external dimensions. For example, they can be rectangles of 110*82mm. The third charging body 3 can be a rectangle of 83*82mm. Thus, the total length of the three charging bodies when unfolded and laid flat can be approximately equal to the length of a 15-inch laptop. Of course, it can also be used with larger laptops, such as... Figure 4 As shown; when the third charging body 3 is attached to the second charging body 2, the sum of the unfolded lengths of the first charging body 1 and the second charging body 2 can be adapted to the length of a 12.7-inch tablet computer, such as... Figure 11 As shown, it can also be used with a laptop computer, such as... Figure 6 As shown; the length and width of the three stacked charging units are approximately equal to the length and width of a 6.7-inch mobile phone, such as... Figure 8 , Figure 9 and Figure 13 As shown; in this configuration, the first battery 12 and the second battery 22 can be in the form of a length of 109mm, a width of 40mm, a thickness of 5.5mm and a capacity of 4000mAh; of course, the above design dimensions can be designed and adjusted according to the relevant dimensions of the first electronic device 6 and the second electronic device 7, which will not be elaborated on here.

[0063] Furthermore, in addition to the charging methods described above, the charging device provided in this embodiment can also provide charging services in at least the following states;

[0064] The first method, see attached document. Figure 7 Appendix Figure 8 and attached Figure 9 In the specific implementation of the charging device provided in this embodiment, the first charging body 1 and the second charging body 2 are stacked, and the third charging body 3 is at a specified angle to the second charging body 2. The second charging body 2 can support the third charging body 3 to be attached to the electronic device. The wireless charging component 4 or the electrical connection port 5 in the third charging body 3 is used to supply power to the electronic device.

[0065] In this configuration, the first charging body 1 rotates to one side of the second charging body 2 and adheres to it. The third charging body 3 rotates in the opposite direction to the first charging body 1 and forms a specified angle with the second charging body 2, which can be, but is not limited to, 30-60 degrees. This allows the first charging body 1 and the second charging body 2 to stack and serve as a base to support the third charging body 3. The third charging body 3 can then be attached to and fixed to the electronic device by adsorption and wirelessly charged via the wireless charging component 4. Alternatively, it can charge the electronic device via the electrical connection port 5, for example: Figure 8 The electronic device shown is horizontally attached to the third charging body 3. Figure 9 The electronic device shown is vertically attached to the third charging body 3; it can also be as follows: Figure 8 As shown, the third charging body 3 wirelessly charges the first electronic device 6, and the electrical connection port 5 is electrically connected to the second electronic device 7 for wired charging. This allows for simultaneous charging of the first electronic device 6 and the second electronic device 7. When the first electronic device 6 is a mobile phone and the second electronic device 7 is a laptop, this charging posture can also achieve simultaneous display and charging of both devices, improving charging and work efficiency.

[0066] The second method is detailed in the appendix. Figure 12 and attached Figure 13 In the case where the first charging body 1, the second charging body 2, and the third charging body 3 are stacked in sequence, the wireless charging component 4 or the electrical connection port 5 in the third charging body 3 is used to supply power to the electronic device.

[0067] In this configuration, the three charging bodies are stacked, forming a charging posture or a storage posture for the charging device. In this configuration, the first charging body 1 rotates towards the first side of the second charging body 2 and adheres to the second charging body 2, while the third charging body 3 rotates in the opposite direction to the first charging body 1 and adheres to the second side of the second charging body 2 opposite to the first side. In this posture, the electronic device can be attached and fixed by the adsorption of the third charging body 3. At this time, wireless charging can be performed through the wireless charging component 4, or wired charging can be performed through the electrical connection port 5. Of course, the first charging body 1 can also be attached and fixed to the electronic device, and wired charging can be performed through the electrical connection port 5.

[0068] The third method, see attached document. Figure 10 and attached Figure 11 At least the first side surface of the second charging body 2 is used to adsorb electronic devices, and the third charging body 3 rotates in a direction away from the first side surface of the second charging body 2 to form a specified angle with the second charging body 2 to support at least the second charging body 2.

[0069] In this configuration, the charging device can form a support structure through changes in its own structure, for example: Figure 10 As shown, the first charging body 1 and the second charging body 2 are parallel and coplanar, i.e., laid flat. The third charging body 3 is rotated to a specified angle with the second charging body 2, for example, 30-150 degrees. This arrangement allows the lines connecting the first charging body 1 and the third charging body 3 to form a triangle with the other charging bodies, providing stable support. This allows the first charging body 1 and the second charging body 2 to both magnetically attach and support the laptop C-shell and tablet computer. In this configuration, wired charging can be performed through the electrical connection port 5. Similarly, the first charging body 1 and the third charging body 3 can be rotated simultaneously to the same side as the second charging body 2, and the rotation can be, but is not limited to, 3. 0-150 degrees; the rotation angles of the two can be the same or different. For example, both can be rotated to a position of 90 degrees, 120 degrees, 60 degrees, etc., relative to the second charging body 2. At this time, the charging device can form a U-shaped frame, a horn-shaped frame, or an inverted horn-shaped frame to provide support. For another example, the first charging body 1 can be rotated to a position of 30 degrees relative to the second charging body 2, and the third charging body 3 can be rotated to a position of 90 degrees relative to the second charging body 2. All of the above forms can achieve both adsorption and support fixation when the second charging body 2 is used with the laptop C-shell and tablet computer. In this posture, wired charging can be performed through the electrical connection port 5.

[0070] The fourth type, see attached document. Figure 5 and attached Figure 6In the specific implementation of the charging device provided in this embodiment, the first charging body 1 and the second charging body 2 are parallel and coplanar, and the third charging body 3 is stacked on top of the second charging body 2. The first charging body 1 and the second charging body 2 can be adsorbed onto the second electronic device 7, and the third charging body 3 can be adsorbed onto the first electronic device 6. The wireless charging component 4 of the third charging body 3 is used to supply power to the first electronic device 6, and the electrical connection port 5 is used to supply power to the second electronic device 7.

[0071] In this setup, the first charging body 1 and the second charging body 2 unfold and lay flat, and can be magnetically fixed to the laptop, which can be, but is not limited to, the C-shell, D-shell, etc., and wired charging is performed through the electrical connection port 5; at this time, the third charging body 3 can be stored on the second charging body 2, or a mobile phone can be magnetically fixed on the side of the third charging body 3 away from the laptop, and the mobile phone can be wirelessly charged, improving charging efficiency and saving space for multiple electronic devices.

[0072] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
