Detailed Implementation

[0048] 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.

[0049] 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.

[0050] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0051] Example 1

[0052] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3 The charging device provided in this application includes a first charging body 1, a second charging body 2, and a first connector 3. The first charging body 1 has a plug 11 at its first end, which is used to electrically connect to a power supply interface to obtain electrical energy. The second end of the first charging body 1 has a first connecting end 12 and a first connecting port 13. The first end of the second charging body 2 has a second connecting end 21 adapted to the first connecting end 12, so that the second charging body 2 can be detachably connected to the first charging body 1 and electrically connected to the first charging body 1. The second charging body 2 has a second connecting port 22, which is used to connect to an electrical device. The first connector 3 has a third connecting port 31 and a fourth connecting port 32 at its two ends, respectively. The third connecting port 31 is adapted to the first connecting port 13 and the second connecting port 22, and the fourth connecting port 32 is used to connect to an electrical device.

[0053] In the case where the first charging body 1 and the second charging body 2 are connected, the first connecting member 3 can be housed between the first charging body 1 and the second charging body 2.

[0054] Understandably, in order to solve the problem of unnecessary arrangement maintenance caused by the large number and chaotic placement of mobile charging devices, this embodiment provides a charging device. It enables the first charging body 1 to charge additional electrical devices or the second charging body 2 through the detachable and connectable arrangement of the first charging body 1 and the second charging body 2. The second charging body 2 can charge additional electrical devices. When the second charging body 2 and the first charging body 1 are combined, the first connector 3 can also be stored. This not only realizes the mobile charging function, but also reduces unnecessary connecting devices and excessive operation to maintain the arrangement by setting up a single first connector 3 and convenient storage. The mobile and temporary operation experience is better.

[0055] Among them, reference appendix Figure 4 The first charging element 1 can convert the AC power supplied by the power grid into DC power suitable for the electrical equipment. Its internal components may include, but are not limited to, a transformer, rectifier circuit, filter circuit, voltage regulator circuit, etc. The first charging element 1 may be, but is not limited to, a power adapter, power switch, etc. The plug 11 is made of conductive metal and can be inserted into a power supply interface for conduction, such as connecting to a wall socket or power strip to obtain power from the mains. The number and shape of the plugs 11 can be designed and adjusted according to the region and usage requirements. For example, the plug 11 can be a two-prong plug, a three-prong plug, a travel adapter plug, etc., and the plug 11 can be cylindrical, flat, etc. In this embodiment, the first connecting end 12 has both structural and electrical connection functions. It can be, but is not limited to, a pogo pin, a pin, etc. Correspondingly, when the first connecting end 12 is a pogo pin, the second connecting end 21 on the second charging body 2 can be a contact point adapted to the pogo pin, or the first connecting end 12 can be set as a contact point and the second connecting end 21 can be set as a pogo pin. The first charging body 1 can supply power to the second charging body 2 to charge it through the first connecting end 12 and the second connecting end 21. In this embodiment, a magnetic attraction structure can also be set around or near the first connecting end 12 and / or the second connecting end 21. It can be, but is not limited to, the cooperation of magnets and metals, the cooperation of magnets and magnets, etc., so that the first charging body 1 and the second charging body 2 can achieve magnetic attraction connection, improving the connection stability of the first connecting end 12 and the second connecting end 21. Of course, the magnetic attraction structure can also be set at the entire end of the charging body where the first connecting end 12 and the second connecting end 21 are located. The first connection port 13 is an electrical connection port, which may be, but is not limited to, USB Type-A, USB Type-B, Mini USB B, Micro USB B, USB Type-C, Lightning, DC plug, etc. The first connection port 13 can connect to an external device via an external cable, thereby supplying power to the external device. The shape and size of the first charging body 1 can be designed and adjusted according to actual needs, and may be, but is not limited to, [specific types of charging bodies]. Figure 4The cross-section shown is a cylindrical structure resembling a runway circle.

[0056] Among them, reference appendix Figure 7 The second charging body 2 can be a storage structure with a discharge function, which may contain a battery, circuit protection system, voltage regulation circuit, charging tube chip, etc. The structure and working principle of the second charging body 2 can be referred to commercially available power banks, and will not be elaborated here. In this embodiment, the second connection port 22 can be a charging interface or a discharging interface, or it can have both charging and discharging functions. For example, the second connection port 22 can be connected to the first charging body 2 through the first connector 3 to charge the second charging body 2, and the second connection port 22 can be connected to an external power device through the first connector 3 to supply power to it. In this embodiment, the second connection port 22 can be, but is not limited to, USB Type-A, USB Type-B, Mini USB B, Micro USB B, USB Type-C, Lightning, DC plug, etc. The second connection port 22 can be located on the same side as the second connection end 21, or on the end of the second charging body 2 opposite to the second connection end 21, or on the side other than the second connection end 21, so that when the first charging body 1 is connected to the second charging body 2, it can also supply power to the external power device through the second connection port 22. The shape and size of the second charging element 2 can be designed and adjusted according to actual needs. For example, it can be adapted to the first charging element 1, i.e. Figure 7 The cross-section shown is a cylindrical structure in the shape of a racetrack circle, and the maximum size of the cross-section of the second charging body 2 can be the same as the maximum size of the cross-section of the first charging body 1. Therefore, when the two are connected to each other, the outer wall of the charging device has no step difference, maintaining a high degree of aesthetic appearance.

[0057] Among them, reference appendix Figure 3The first connector 3 is a structure capable of power transmission, and may be, but is not limited to, a power cable, adapter, or connector. The two ends of the first connector 3 are respectively provided with a third connection port 31 and a fourth connection port 32. Both the third connection port 31 and the fourth connection port 32 are electrical connection ports, and may be, but are not limited to, USB Type-A, USB Type-B, Mini USB B, Micro USB B, or USB... Type-C, Lightning, DC plugs, etc., the third connector 31 and the fourth connector 32 can be the same or different; in this embodiment, the third connector 31 is adapted to the first connector 13 and the second connector 22, so the third connector 31 can be electrically connected to the first charging body 1 through the first connector 13, and use the fourth connector 32 to supply power to the device. The third connector 31 can also be electrically connected to the second charging body 2 through the second connector 22, and use the fourth connector 32 to supply power to the device. It is easy to understand that the device that can be connected to the fourth connector 32 can be the second charging body 2 or an additional device, such as, but not limited to, mobile phones, laptops, tablets, etc., so the first charging body 1 can be used alone with the first connector 3 to charge the device, such as... Figure 11 As shown in the diagram; the second charging unit 2 can independently work with the first connector 3 to charge the electrical device, such as... Figure 13 In the state shown, the first charging body 1 can also charge the second charging body 2 through the first connector 3, as shown. Figure 12 The state is shown. Accordingly, in this embodiment, the first connection port 13, the second connection port 22, and the third connection port 31 can be the same interface, such as a USB Type-C interface, which makes it more convenient to perform adapter connections. At the same time, the fourth connection port 32 can be set to be the same interface as the above three connection ports, so that the first connector 3 has a foolproof function, and can achieve connection with charging devices and electrical equipment regardless of which connection port, reducing the accuracy requirements of the connection. The length of the first connector 3 can be designed and adjusted according to actual needs, such as 1m, 1.5m, 2m, etc.

[0058] In order to reduce the complexity of storing the first charging body 1, the second charging body 2, and the first connector 3, this embodiment can utilize the accommodating space formed when the first charging body 1 and the second charging body 2 are connected to accommodate the first connector 3. This space can be a groove or an entanglement area formed when the two are connected. For example, when the first connecting end 12 and the second connecting end 21 are connected, there is a height difference on the outer shell of the corresponding ends of the two charging bodies, which creates a groove or an entanglement area. The first connector 3 can then be placed in the groove or wrapped around the entanglement area, so that the first connector 3 can form an integral structure with the two charging bodies, avoiding the chaotic placement of the three.

[0059] According to the above, the charging device provided in this application allows the first charging body and the second charging body to be used separately or as a whole. The first connector can also be stored between the two charging bodies. The first connector can also be used to charge the electrical equipment and the second charging body. This not only realizes the mobile charging function but also effectively improves the convenience and order of accessory storage. This solves the problem of unnecessary maintenance of arrangement order caused by the large number of mobile charging devices and their chaotic placement.

[0060] 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.

[0061] Further, see attached document. Figure 3 In the specific implementation of the charging device provided in this embodiment, when the first charging body 1 and the second charging body 2 are connected, a receiving space is formed between the first charging body 1 and the second charging body 2 around the first direction a; the first connector 3 can be housed in the receiving space around the first direction a; wherein, the first direction a is the direction in which the plug 11 points to the first connecting end 12.

[0062] It is understandable that, in order to improve the storage convenience of the first connector 3, the storage method of the first connector 3 is set to a winding form in this embodiment. After use, the first connector 3 can be directly wound without forming a specified shape or size and placing it in a fixed-size receiving space. In this embodiment, when the first charging body 1 and the second charging body 2 are connected, a receiving space around the first direction a is formed at the connection position. This space can be, but is not limited to, an annular groove. For example, the ends where the first connecting end 12 and / or the second connecting end 21 are located are extended outward relative to the charging body, and the dimension of the ends around the first direction a is smaller than the dimension of the outermost part of the charging body around the first direction a. Thus, after the two are connected, a step difference area is formed between them relative to the outermost parts of the two charging bodies, which forms an annular groove. The first connector 3 can be wound in the annular groove. The size of the annular groove can be designed and adjusted according to actual needs. It can be in the form of ensuring that the outer surface of the first connector 3 after winding is flush with the outer surface of the two charging bodies, effectively improving the overall appearance and consistency of the charging device.

[0063] Further, see attached document. Figure 5 and attached Figure 6In this embodiment, the charging device includes a first charging body 1 comprising a body 14 and a housing 15. A plug 11 is disposed on the body 1. The housing 15 is slidably connected to the body 14 along the first direction a, so that the housing 15 can slide relative to the body 14 to accommodate or expose the plug 11. When the first charging body 1 and the second charging body 2 are connected and the housing 15 is slid to accommodate the plug 11, the accommodating space is formed between the housing 15 and the second charging body 2.

[0064] Understandably, to improve the aesthetics of the charging device, in this embodiment, the first charging body 1 is configured such that the outer shell 15 and the main body 14 can slide relative to each other. When the outer shell 15 houses the plug 11, it can cooperate with the second charging body 2 to form a receiving space. When the plug 11 is exposed, the receiving space can be hidden, preventing a permanent difference in height between the inner and outer sections of the receiving space or the first charging body 1, which would affect both the visual effect and the smoothness of the grip. Correspondingly, both the main body 14 and the outer shell 15 are rigid structures. The main body 14 houses all the functional components required for the first charging body 1, including the plug 11, the first connecting end 12, and the second connecting port 13. The outer shell 15 is an opaque shell, and its sliding relative to the main body 14 can be achieved by providing a slide rail 17, a groove, or a track on the main body 14, combined with a slider or pulley on the inner wall of the outer shell 15. Figure 6 The setup shown can also be modified by installing sliders, pulleys, or other structures on the outer wall of the main body 14, and installing slides, grooves, or rails on the inner wall of the outer shell 15. Alternatively, sliding structures can be installed on opposite sides of the main body 14 to ensure smooth and stable sliding. This setup is easily understood by those skilled in the art and will not be elaborated upon here. Correspondingly, when the first connector 3 needs to be housed, the outer shell 15 is slid towards the plug 11 to house or hide the plug 11 within the outer shell 15. This can be partial or complete concealment. At this point, the main body 14 containing the second connector 12 is exposed. After connecting the first connector 12, an annular groove is formed between the outer shell 15, the outer wall of the second charging body 2, and the main body 14 exposed outside the outer shell 15, thus forming the charging device. Figure 3 State. When the first connector 3 is not needed, the outer casing 15 can be slid towards the first connector 12 or reset to expose the plug 11. At this time, the plug 11 can automatically connect to the power supply interface. The plug 11 can supply power to the device through the first connector 13. Of course, it can also supply power to the second charging body 2 through the connection of the first connector 12 and the second connector 21. It can also supply power to additional devices through the connection of the first connector 12 and the second connector 21 via the second connector 22. Figure 2The state is shown. Accordingly, refer to the appendix. Figure 4 In this embodiment, a guide wall 16 can also be provided around the second end of the body 14 in the circumferential direction of the first direction a. The guide wall 16 is inclined or arc-shaped towards the center of the body 14 in the opposite direction of the first direction a, so as to guide when connecting the second charging body 2. Of course, the corresponding position of the second charging body 2 is set to the corresponding shape to improve adaptability.

[0065] Accordingly, see Appendix Figure 10 To maintain the stability of the first connector 3 after winding, a fixing member 6 can be provided on the first connector 3 in this embodiment. The fixing member 6 is sleeved on the first connector 3, and the fixing member 6 has an opening groove 61 to movably clamp it to other positions of the first connector 3. The fixing member 6 can be rigid or flexible, or the part sleeved on the first connector 3 can be rigid and the part with the opening groove 61 can be flexible, and the part sleeved on the first connector 3 can move along the axial direction of the first connector 3. In use, the fixing member 6 can be moved to the end of the winding process of the first connector 3. After winding is completed, the opening groove 61 is clamped on the already wound first connector 3 to achieve end fixation. Of course, the fixing member 6 can also be moved to the beginning of the winding of the first connector 3. After winding is completed, the opening groove 61 is clamped on the end of the first connector 3. It is easy to understand that the shape of the opening groove 61 is adapted to the shape of the first connector 3, and can be C-shaped, U-shaped, etc.

[0066] Furthermore, in the specific implementation of the charging device provided in this embodiment, the inner wall of the outer shell 15 is provided with a first fastener (not shown in the figure); the outer wall of the main body 14 is provided with a second fastener (not shown in the figure) that is adapted to the first fastener, so that the outer shell 15 can maintain the state of storing or exposing the plug 11.

[0067] It is understandable that, in order to ensure the stability of the outer shell 15, a first latching member and a second latching member are provided in this embodiment. The first latching member and the second latching member can both be rigid structures, both be elastic structures, or one can be rigid and the other elastic. The first latching member protrudes from the outer wall of the main body 1, and the second latching member protrudes from the inner wall of the outer shell 15. The two can be staggered in position during sliding through interference fit or elastic deformation. After staggering, they form mutual limiting and can be released under the sliding action of a large external force. For example, a first protrusion structure (not shown in the figure) and a second protrusion structure (not shown in the figure) are respectively provided on the outer walls of both ends of the main body 14 along the first direction a. Protrusions or several protrusions distributed at intervals around the first direction a are provided on opposite sides of the inner wall of the outer shell 15. When the outer shell 15 slides along the first direction a until the protrusions pass the second protrusion structure, the second protrusion structure prevents the outer shell 15 from moving towards the plug 11, so the outer shell 15 remains in the state of exposing the plug 12. Figure 4 As shown, when the outer casing 15 slides in the opposite direction of the first direction a until the protrusion passes the first protrusion structure, the first protrusion structure prevents the outer casing 15 from moving towards the first connecting end 12, and the outer casing 15 remains in the state of storing the plug 11. Figure 5 The state shown.

[0068] Further, see attached document. Figure 7 In the specific implementation of the charging device provided in this embodiment, the second connection port 22 of the second charging body 2 is located at the end opposite to the second connection end 21; the first end of the second charging body 2 is also provided with a fifth connection port 23, which is adapted to the fourth connection port 32 of the first connector 3.

[0069] Understandably, to improve the convenience of the second connection port 22 in supplying power to external electrical devices and to prevent the first charging body 1 and the second charging body 2 from obstructing the second connection port 22 when they are combined, in this embodiment, the second connection port 22 can be located at the end opposite to the second connection end 21, or at a side other than the second connection end 21. Furthermore, in this embodiment, a fifth connection port 23 can also be provided on the side where the second connection end 21 is located. The fifth connection port 23 is an electrical connection port, which is compatible with the fourth connection port 32. The specific type is described above and will not be repeated here. The fifth connection port 23 can be either an input interface or an output interface for the second charging body 2. Therefore, the fifth connection port 23 can receive power from the first charging body 1 through the first connector 3, and can also supply power to additional electrical devices through the first connector 3. (See attached diagram.) Figure 8In this embodiment, a display screen 24 may also be provided on the second charging body 2 adjacent to the fifth connection port 23. The display screen 24 is electrically connected to the battery, charging management chip and other functional components in the second charging body 2, and can at least display the remaining power of the second charging body 2. This setting can be easily understood by those skilled in the art, and will not be described in detail here.

[0070] Further, see attached document. Figure 8 In a specific implementation, the charging device provided in this embodiment may further include a second connector 4; one end of the second connector 4 is electrically connected to the second charging body 2, and the second end of the second connector 4 is provided with a sixth connection port 41, which is used to electrically connect to the electrical equipment; wherein, the length of the second connector 4 is different from the length of the first connector 3.

[0071] It is understandable that, in order to improve the usability of the charging device, a second connector 4 is provided in this embodiment. The second connector 4 is a structure capable of power transmission, and can be, but is not limited to, a power transmission cable, adapter, or connector. The second connector 4 is electrically connected to the battery, charging management chip, voltage regulation circuit, and other functional components in the second charging body 2 to achieve external power transmission. This configuration is easily understood by those skilled in the art and will not be elaborated here. In this embodiment, the second connector 4 is fixedly connected to the second charging body 2 and cannot be disassembled to avoid maintaining order during operation. For example, the second charging body 4 has a receiving slot, and the second connector 4 can be stored in the receiving slot. The receiving slot can be set along the first direction a or around the first direction a. The length of the second connector 4 can be greater than or less than the length of the first connector 3, preferably less than the length of the first connector 3, to improve the convenience of independent use of the second charging body 2. In use, the second connector 4 can also be used simultaneously with the first connector 3, for example... Figure 13 As shown, the first connector 3 and the second connector 4 are connected to the mobile phone and the laptop respectively. The longer first connector 3 improves the convenience of mobile charging, while the shorter second connector 4 works in conjunction with the simultaneous clamping action of the second charging body 2 and the laptop. The sixth connection port 41 is an electrical connection port, which can be, but is not limited to, USB Type-A, USB Type-B, Mini USB B, Micro USB B, USB Type-C, Lightning, DC plug, etc. It is used to connect external power devices, which can be, but are not limited to, mobile phones, tablets, laptops, cameras, fans, etc.

[0072] Further, see attached document. Figure 7In this embodiment, the charging device further includes a third connector 5. The first end of the third connector 5 is electrically connected to the second charging body 2, and the second end of the third connector 5 is provided with a seventh connector 51 for electrically connecting to electrical equipment. The seventh connector 51 and the sixth connector 41 can be detachably connected along a second direction b, where the second direction b is the insertion / removal direction of the seventh connector 51 or the sixth connector 41.

[0073] It is understandable that, in order to improve the usability of the charging device, a third connector 5 is provided in this embodiment. The third connector 5 is a structure capable of power transmission, and can be, but is not limited to, a power transmission cable, adapter, or connector. The third connector 5 is electrically connected to the battery, charging management chip, voltage regulation circuit, and other functional components in the second charging body 2 to achieve external power transmission. The third connector 5 is connected in parallel with the second connector 4. This configuration is easily understood by those skilled in the art and will not be elaborated here. In this embodiment, the third connector 5 is fixedly connected to the second charging body 2 and cannot be disassembled to avoid maintaining order during operation. For example, the second charging body 4 has a receiving slot, and the third connector 5 can be housed in the receiving slot. The receiving slot can be set along the first direction a or around the first direction a; the length of the third connector 5 can be the same as that of the second connector 4. The seventh connection port 51 is an electrical connection port, which can be, but is not limited to, USB Type-A, USB Type-B, Mini USB B, MicroUSB B, USB Type-C, Lightning, DC plug, etc. It is used to connect external power devices, including but not limited to mobile phones, tablets, laptops, cameras, fans, etc. The seventh connection port 51 can be the same as or different from the sixth connection port 41. In use, the sixth connection port 41 and the seventh connection port 51 can each be connected to a power device for charging, such as... Figure 12 In the state shown, under this configuration, the charging management chip inside the second charging unit 2 has a real-time dynamic sensing function. It can detect and display the power level, and automatically identify and match the required output power to each of the three connectors, achieving fast and safe charging. This configuration is easily understood and implemented by those skilled in the art, and will not be elaborated further here. In this embodiment, the sixth connector 41 and the seventh connector 51 can be configured to be plugged into each other for storage, which saves space and keeps the interior of the sixth connector 41 and the seventh connector 51 clean, preventing dirt from affecting the output function. For example, a shell with a receiving space can be provided on the outside of each interface to accommodate the other interface. When the sixth connector 41 and the seventh connector 51 are connected, they can be, but are not limited to, in a stacked form. For example: refer to the attached... Figure 9The sixth connection port 41 is provided with a first receiving groove 42, which is adapted to the seventh connection port 51; the seventh connection port 51 is provided with a second receiving groove 52, which is adapted to the sixth connection port 41; the first receiving groove 42 and the second receiving groove 52 can be formed by fitting an annular shell 7 over the sixth connection port 41 and the seventh connection port 51, as shown in the attached figure. Figure 7 Taking the sixth connection port 41 side as an example, two receiving slots can be formed inside the annular shell. The openings of the receiving slots are all opposite to the second charging body 2. One receiving slot is used to accommodate the sixth connection port 41, and the other receiving slot is used to accommodate the seventh connection port 51. The design of the annular shell on the seventh connection port 51 side is similar and will not be described in detail here. In this embodiment, a snap-fit ​​component can also be provided at the joint end of the two shells. The snap-fit ​​component can refer to the cooperation design of the first snap-fit ​​component and the second snap-fit ​​component mentioned above, and will not be described in detail here. In this embodiment, the annular shell can be rigid or flexible.

[0074] Further, see attached document. Figure 8 In the specific implementation of the charging device provided in this embodiment, the second charging body 2 includes a second body 25 and a second outer shell 26; one end of the second outer shell 26 facing the second end of the second body 25 is spaced apart from the second body 25 so that the second connector 4 and / or the third connector 5 can be housed between the second body 25 and the second outer shell 26.

[0075] Understandably, to improve the aesthetics and neatness of the charging device, this embodiment can form a space inside the second charging body 2 to accommodate the second connector 4 and the third connector 5. Specifically, the second charging body 2 is configured to include a second body 25 and a second outer shell 26. The second body 25 contains functional components such as a battery, power management chip, and voltage regulation circuit. The second outer shell 26 is fixedly covered outside the second body 25, and can be made of materials such as plastic or rubber, serving both protective and aesthetic purposes. The second outer shell 26 can be rigid or flexible, and can be transparent or opaque. Accordingly, in this embodiment, one end of the second outer shell 26 corresponding to the third connection port 31 is configured to form a gap with the second body 25 and be connected to the outside, so that the second connector 4 and / or the third connector 5 can be wound around the second body 25 in the first direction a within the gap for storage. Correspondingly, in this embodiment, a locking port 27 can also be provided on the second outer shell 26, so that the second connector 4 and / or the third connector 5 can be locked in the locking port 27 after being wound around in the gap, improving the neatness of the appearance. In this embodiment, the second connector 4 and the third connector 5 can be set to the same length or different lengths. The design can be based on half the circumference of the second body 25 around the first direction a. Taking the second connector 4 as an example, its total length can be 120mm. After it is wrapped in the gap, it can leave a length of 50mm outside the second charging body 2. Therefore, when in use, the second connector 4 and the third connector 5 can be adapted to be pulled out of the gap or not pulled out of the gap to accommodate different electrical devices.

[0076] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
