[0003] The embodiments of this application provide a charging device that can improve the convenience of charging.

[0004] This application provides a charging device. The charging device includes a housing, a circuit board, an input component, and a first retractable cable module and a second retractable cable module. The circuit board is disposed within the housing. The input component is electrically connected to the circuit board. The first and second retractable cable modules include a carrier and a retractable cable wound along a preset winding axis and supported on the carrier. The carrier is assembled within the housing. One end of the retractable cable is electrically connected to the circuit board, and the other end of the retractable cable has a connector. The connectors of the first and second retractable cable modules are exposed on opposite sides of the housing.

[0005] Optionally, the charging device further includes two locking members, which are respectively disposed on opposite sides of the housing and are used to lock the connectors of one of the first telescopic cable modules and the second telescopic cable module respectively. In the locked state, the free ends of the two connectors point to the same side of the housing.

[0006] Optionally, the two locking members have the same structure and are respectively assembled on opposite sides of the housing, and are mirror-symmetrical along a preset first plane of symmetry.

[0007] Optionally, the first telescopic line module and the second telescopic line module have the same structure and are rotationally symmetrical along a preset rotation axis.

[0008] Optionally, the carrier includes a first main sidewall and a second main sidewall spaced apart along the winding axis, and a peripheral sidewall connecting the first main sidewall and the second main sidewall. The peripheral sidewall has a lead-out side, and the telescopic line is wound between the first main sidewall and the second main sidewall. The joint is located on the side of the lead-out side away from the carrier. The lead-out sides of the two carriers face opposite directions, and the first main sidewall and the second main sidewall of the two carriers are inverted relative to each other.

[0009] Optionally, the first telescopic cable module and the second telescopic cable module include connectors also disposed on the carrier, the connectors being electrically connected to the telescopic cable; the first main sidewall is provided with an opening, and the terminals of the connectors are exposed from the opening.

[0010] Optionally, the circuit board includes a main circuit board and two adapter boards. The two adapter boards are located on the same side of the first telescopic cable module and the second telescopic cable module and are electrically connected to the main circuit board respectively. The two adapter boards are respectively connected to one of the two connectors via ribbon cables.

[0011] Optionally, the electrical connection points between the two adapter plates and their respective ribbon cables are both located on the side of the first main sidewall of one of the two carriers that faces away from the second main sidewall, and the ribbon cable corresponding to one of the two adapter plates extends in a bent manner to the side of the first main sidewall of the carrier corresponding to the adapter plate that faces away from the second main sidewall.

By exposing the connectors of the first and second retractable cable modules on opposite sides of the casing, a charging device can have two relatively independent connectors, allowing the user to use different retractable cables from either side of the casing to charge the electronic device as needed. This improves the convenience of charging. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Combination Figures 1 to 3 This application provides a charging device 1. The charging device 1 includes a housing 10, a circuit board 30, a first retractable cable module 201, and a second retractable cable module 202. The housing 10 forms a space to accommodate the circuit board 30, the first retractable cable module 201, and the second retractable cable module 202, and provides mechanical support for them. The housing 10 also forms the appearance of the charging device 1. The circuit board 30 can transform and convert current, and manage the input and output of current. The retractable cables in the first retractable cable module 201 and the second retractable cable module 202 can be extended by pulling when the user takes them out, facilitating insertion and removal. The first retractable cable module 201 and the second retractable cable module 202 can also be automatically retracted after being removed by the user. The first retractable cable module 201 and the second retractable cable module 202 also include connectors 25 disposed on a carrier member 21. The two connectors 25 in the first telescopic cable module 201 and the second telescopic cable module 202 are oriented in opposite directions.

[0023] Further integration Figure 5 and Figure 6 In some embodiments, the charging device 1 further includes an input component. The input component may include an input interface 33 and a power converter. The input component is capable of connecting to a power source to power the circuit board 30 and the first retractable cable module 201 and the second retractable cable module 202. The power converter is capable of converting alternating current to direct current, thereby facilitating the supply of a suitable standard current to the electronic equipment.

[0024] In some embodiments, the charging device 1 further includes a power cord for connecting the input interface 33 to a power source. The power cord can be a power adapter, capable of connecting to mains power and transforming the current before inputting it to the circuit board 30 via the input interface 33. The circuit board 30 manages and distributes the input current to charge the electronic device. Alternatively, the power cord can be a wire directly connected to mains power, with the transformation process implemented using an adapter within the circuit board 30.

[0025] In some embodiments, the charging device 1 further includes an energy storage component, which is installed within the housing 10 and electrically connected to the circuit board 30. In other words, the charging device 1 can power the electronic device without being connected to a power cord. The energy storage component can be charged via the aforementioned power cord and input component.

[0026] Combination Figures 3 to 5 In some embodiments, the first retractable cable module 201 and the second retractable cable module 202 include a carrier member 21 and a retractable cable wound and supported on the carrier member 21 along a preset winding axis. The carrier member 21 is assembled within the housing 10. The winding structure of the first retractable cable module 201 and the second retractable cable module 202 can automatically retract the retractable cable, reducing cable clutter, and the length adjustment function adapts to the charging distance requirements of different electronic devices. The carrier member 21 is assembled within the housing 10, allowing the first retractable cable module 201 and the second retractable cable module 202 to be manufactured separately and then assembled into the housing 10, which helps reduce the manufacturing cost of the charging device 1. The assembly of the carrier member 21 within the housing 10 also facilitates later maintenance and replacement. It should be noted that, apart from the structure mentioned in this application, the other structures of the first retractable cable module 201 and the second retractable cable module 202 can be completely the same or different, and no specific limitation is made here.

[0027] One end of the retractable cable is electrically connected to the circuit board 30, and the other end is equipped with a connector 24. Connector 24 can be a Type-C, Lightning, USB, or other standard interface. Users can extend the retractable cable through connector 24 and then plug connector 24 into the electronic device. The retractable cable allows the current managed by the circuit board 30 to be input into the electronic device through connector 24.

[0028] Combination Figure 6In some embodiments, the circuit board 30 includes a main circuit board 31 and at least one adapter plate 32. The adapter plate 32 is disposed along one edge of the main circuit board 31, and the main surface of the adapter plate 32 intersects the main surface of the main circuit board 31. The main surface of the main circuit board 31 may refer to the upper surface of the base plate in the main circuit board 31. The main surface of the adapter plate 32 may refer to the surface of the adapter plate 32 facing the first telescopic cable module 201 and the second telescopic cable module 202. In other words, the thickness direction of the adapter plate 32 intersects the thickness direction of the main circuit board 31. Optionally, the thickness direction of the main circuit board 31 and the thickness direction of the adapter plate 32 are perpendicular to each other.

[0029] Combination Figure 5 The first telescopic cable module 201 and the second telescopic cable module 202 each include a telescopic cable wound along a preset winding axis pointing towards the main circuit board 31. The projections of the first telescopic cable module 201 and the second telescopic cable module 202 in a direction perpendicular to the winding axis at least partially overlap with the adapter plate 32. The telescopic cables are electrically connected to the main circuit board 31 via the adapter plate 32. By connecting the adapter plate 32 to the main circuit board 31, the adapter plate 32 can be easily connected to the first telescopic cable module 201 and the second telescopic cable module 202 via a ribbon cable. Furthermore, by setting the projections of the first telescopic cable module 201 and the second telescopic cable module 202 in the direction perpendicular to the winding axis to at least partially overlap with the adapter plate 32, the adapter plate 32 can share the same thickness with the first telescopic cable module 201 and the second telescopic cable module 202 in the winding axis direction. This facilitates the connection between the circuit board 30 and the first telescopic cable module 201 and the second telescopic cable module 202 while reducing the space occupied by the adapter plate 32, thereby helping to reduce the size of the charging device 1. In other words, the main circuit board 31 and the adapter plate 32 can form an accommodating space for the first telescopic cable module 201 and the second telescopic cable module 202, which can improve space utilization and facilitate cable routing.

[0030] In some embodiments, the input interface 33 is disposed on the main circuit board 31. The main circuit board 31 is provided with, for example, a power converter or a current management circuit. The input interface 33 is connected to the main circuit board 31 to input current into the main circuit board 31, and the main circuit board 31 can input current into each adapter board 32 or the output control board 34 described later.

[0031] Combination Figure 5 and Figure 6In some embodiments, the charging device 1 includes a first retractable cable module 201 and a second retractable cable module 202. The connectors 24 of the first retractable cable module 201 and the second retractable cable module 202 are exposed on opposite sides of the housing 10. The first retractable cable module 201 and the second retractable cable module 202 can store the retractable cable, and the user can extend it to the required length to charge the electronic device. By exposing the connectors 24 of the first retractable cable module 201 and the second retractable cable module 202 on opposite sides of the housing 10, a charging device 1 can have two relatively independent connectors 24, allowing the user to use different retractable cables from opposite sides of the housing 10 to charge the electronic device as needed. By providing two connectors 24 located on opposite sides of the housing 10, charging needs in different directions can be met simultaneously, avoiding the limitations of traditional single-sided connectors 24. This improves the convenience of charging.

[0032] In some embodiments, there are two adapter boards 32, which are electrically connected to the corresponding retractable wires of the first retractable wire module 201 and the second retractable wire module 202 via ribbon cables. In this way, the first retractable wire module 201 and the second retractable wire module 202 can be corresponding to the adapter boards 32, so that the connection between the two can be made through simple wiring, reducing the complexity of wiring within the housing 10 and reducing the space required for wiring.

[0033] Furthermore, two adapter boards 32 are positioned on the same side of the first telescopic cable module 201 and the second telescopic cable module 202, with the two adapter boards 32 spaced apart on both sides of the input interface 33. In other words, the two adapter boards 32 are positioned on the edge of the same side of the main circuit board 31. This arrangement makes the circuit connection more direct. The routing paths between electronic components are shorter, reducing the possibility of line crossings. Furthermore, the power distribution lines starting from the input interface 33 can be easily connected to the two adapter boards 32, avoiding complex routing and multiple connection points, which helps reduce electromagnetic interference and improve circuit signal integrity. This layout also frees up other sides of the main circuit board 31, thus facilitating further circuit expansion.

[0034] Furthermore, the two adapter boards 32 have identical structures and are assembled onto the main circuit board 31, with the two adapter boards 32 being mirror-symmetrical along a preset second plane of symmetry. This identical structure and mirror-symmetrical arrangement allows the adapter boards 32 to utilize the same molds and processes during production, thus reducing production costs. The mirror-symmetrical arrangement of the adapter boards 32 simplifies the assembly process, making it more intuitive and improving assembly speed and accuracy. The mirror-symmetrical adapter boards 32 also ensure electrical consistency during current flow from the input interface 33, circuit board 30, to the adapter boards 32. This electrical consistency simplifies the design of the circuit board 30.

[0035] Combination Figure 5 In some embodiments, the electrical connections between the two adapter boards 32 and their respective ribbon cables are located on the side of the two carriers 21 facing away from the main circuit board 31. In this way, the space in the direction perpendicular to the main surface of the main circuit board 31 can be fully utilized, giving the adapter board 32 sufficient space to arrange its required electronic components. Furthermore, since the adapter board 32 shares a certain space with the first telescopic cable module 201 and the second telescopic cable module 202 in the direction perpendicular to the main surface of the main circuit board 31, the adapter board 32 formed in the above manner can achieve sufficient arrangement of electronic components without occupying more space.

[0036] Combination Figure 3 In some embodiments, the charging device 1 further includes two locking members 40, which are respectively disposed on opposite sides of the housing 10 and used to lock the connector 24 of one of the corresponding components of the first telescopic cable module 201 and the second telescopic cable module 202. The locking member 40 is a structural component for fixing the connector 24 and can be a snap-fit ​​structure or a magnetic adsorption structure made of elastic material. By providing locking members 40 on opposite sides, the positions of the connectors 24 of the first telescopic cable module 201 and the second telescopic cable module 202 can be fixed respectively, reducing the displacement or detachment of the connectors 24 during storage. In the locked state, the free ends of the two connectors 24 point to the same side of the housing 10. "The free ends of the connectors 24 point to the same side" means that when the two connectors 24 are locked, their ends both face the same direction of the housing 10, for example, both facing the front end face of the housing 10. When the first telescopic cable module 201 and the second telescopic cable module 202 retract, the free ends of the connectors 24 maintain a uniform orientation under the constraint of the locking member 40, reducing cable tangling or interference. The locking member 40 can be located in a recessed area on the side wall of the housing 10, ensuring that the connectors 24 face the extension direction of the housing 10 surface. The uniform orientation of the free ends of the connectors 24 makes the cable arrangement neater, reduces space occupation, and improves operational convenience. When using the connectors 24 on either side, users do not need to consciously distinguish their usage direction; the uniform orientation of the connectors 24 facilitates quick identification and insertion / removal, improving usage efficiency.

[0037] In some embodiments, the two locking members 40 have the same structure and are respectively assembled on opposite sides of the housing 10, and are mirror-symmetrical along a preset first plane of symmetry. The locking members 40 can be located on opposite sides outside the housing 10, or they can be located on opposite sides inside the housing 10 and exposed through notches; no specific limitation is made here. By setting locking members 40 with the same structure and mirror-distributing them along the plane of symmetry, it is possible to ensure that the forces on both sides are symmetrical and uniform, thereby improving the overall structural stability. The mirror-symmetrical design simplifies the assembly process and reduces installation errors. Locking members 40 with the same structure can reduce the types of parts and lower production costs. Optionally, the first plane of symmetry and the second plane of symmetry can be the same plane.

[0038] In some embodiments, the first retractable cable module 201 and the second retractable cable module 202 have the same structure and are rotationally symmetrical about a preset rotation axis. The identical structure of the first retractable cable module 201 and the second retractable cable module 202 allows for a unified processing technology, reducing manufacturing costs and maintenance difficulty. The symmetrical layout also optimizes space utilization, making the overall structure of the charging device 1 more compact. In other words, although the first retractable cable module 201 and the second retractable cable module 202 disposed in the housing 10 need to face different directions, they can be achieved using the same first retractable cable module 201 and the same second retractable cable module 202. In this way, only one type of retractable cable module needs to be produced, and during assembly, the first retractable cable module 201 and the second retractable cable module 202 are assembled in different directions, enabling the connector 24 to be located on opposite sides of the housing 10.

[0039] Combination Figure 4In some embodiments, the carrier 21 includes a first main sidewall 211 and a second main sidewall 212 spaced apart along the winding axis, and a peripheral sidewall 213 connecting the first main sidewall 211 and the second main sidewall 212. A telescopic cable is wound between the first main sidewall 211 and the second main sidewall 212. The first main sidewall 211, the second main sidewall 212, and the peripheral sidewall 213 can enclose a space to accommodate the telescopic cable. The peripheral sidewall 213 has a lead-out side, and a connector 24 is located on the lead-out side opposite to the carrier 21. The peripheral sidewall 213 may have an outlet for the telescopic cable to pass through. The outlet can be located on the lead-out side or on other sides of the peripheral sidewall 213; no specific limitation is made here, but the connector 24 is located on the lead-out side when retracted. Furthermore, the lead-out sides of the two carriers 21 face opposite directions; in other words, the sides of the first telescopic cable module 201 and the second telescopic cable module 202 with the connector 24 face away from each other. Furthermore, the first main sidewalls 211 and the second main sidewalls 212 of the two support members 21 are inverted relative to each other. In other words, the first main sidewalls 211 of the two support members 21 face opposite directions, and the second main sidewalls 212 of the two support members 21 face opposite directions. In this way, the two identical first telescopic cable modules 201 and second telescopic cable modules 202 can be inverted relative to each other so that the connectors 24 face opposite directions, thereby allowing each side of the housing 10 to have a connector 24. In the above manner, the two identical first telescopic cable modules 201 and second telescopic cable modules 202 can be assembled with different orientations, which helps to reduce the manufacturing cost of the charging device 1.

[0040] In some embodiments, the first retractable cable module 201 and the second retractable cable module 202 include connectors 25 also disposed on the carrier 21, and the connectors 25 are electrically connected to the retractable cables. The connectors 25 enable the circuit board 30 to connect to the first retractable cable module 201 and the second retractable cable module 202. One end of the connector 25 may be provided with a terminal for connection to a ribbon cable, and the other end of the connector 25 may be provided with an annular contact piece for abutting against the terminal of the retractable cable, thereby achieving a stable electrical connection with the connector 25 when the retractable cable is in motion. The two connectors 25 in the first retractable cable module 201 and the second retractable cable module 202 face opposite directions. Further, the first main sidewall 211 is provided with an opening, through which the terminals of the connectors 25 are exposed. Two adapter plates 32 are respectively connected to one of the corresponding connectors 25 via ribbon cables, thereby achieving the electrical connection between the circuit board 30 and the first retractable cable module 201 and the second retractable cable module 202.

[0041] By employing the above method, the portions of the first retractable cable module 201 and the second retractable cable module 202 used for connecting to the circuit board 30 can be oriented towards opposite sides, reducing excessive space occupation on one side due to wiring. It also reduces the problem of cross-cutting of cables that might occur when wiring is on the same side. The opposite orientation of the connectors 25 also allows for a greater distance between the two connectors 25, thereby reducing heat dissipation or electromagnetic interference between them. When the first retractable cable module 201 and the second retractable cable module 202 have the same structure, the two connectors 25 facing opposite directions allow the protrusion directions of the connectors 24 of the first retractable cable module 201 and the second retractable cable module 202 to be opposite, thus preventing interference between the winding paths of the retractable cables. Through this method, the first retractable cable module 201 and the second retractable cable module 202, which are inverted, can be formed within the housing 10, and their winding paths can be opposite. By reversing their arrangement, the space utilization inside the housing 10 can be improved, and the first telescopic cable module 201 and the second telescopic cable module 202 can be made relatively independent and do not interfere with each other.

[0042] Combination Figure 5 and Figure 6In some embodiments, the electrical connection points between the two adapter plates 32 and their respective ribbon cables are all located on the side of the first main sidewall 211 of one of the two carriers 21 that faces away from the second main sidewall 212. The ribbon cable corresponding to one of the two adapter plates 32 extends in a bent manner to the side of the first main sidewall 211 of the carrier 21 corresponding to that adapter plate 32 that faces away from the second main sidewall 212. In other words, the opening of the exposed connector 25 terminal of the carrier 21 in the first telescopic cable module 201 faces away from the main circuit board 31, and the opening of the exposed connector 25 terminal of the carrier 21 in the second telescopic cable module 202 faces towards the main circuit board 31. The electrical connection points between the two adapter plates 32 and their respective ribbon cables are all located on the side of the two carriers 21 that faces away from the main circuit board 31. In this case, the telescopic cable module (first telescopic cable module 201) with the opening on the carrier 21 facing away from the main circuit board 31 can be directly connected to the adapter plate 32 via a ribbon cable. The ribbon cable for the other retractable cable module (second retractable cable module 202) can be led out from the adapter plate 32, then extended in a bent manner between the second retractable cable module 202 and the main circuit board 31, and then connected to the connector 25. This method reduces cross-interference in circuit layout and optimizes space utilization. The bent extension of the ribbon cable can adapt to different installation requirements, so that although the first retractable cable module 201 and the second retractable cable module 202 are installed upside down, they can still be connected to the circuit board 30 through direct connection and bending, respectively. This connection method, achieved by changing the cable routing, is simple, easy to implement, and low in cost.

[0043] Combination Figure 3 In some embodiments, the housing 10 includes two spaced-apart main housing walls 11. The winding axes of the first telescopic cable module 201 and the second telescopic cable module 202 point towards the main housing wall 11. The two main housing walls 11 are perpendicular to the winding axes, and the winding axes of the first telescopic cable module 201 and the second telescopic cable module 202 are parallel to each other. The space formed by the two main housing walls 11 can accommodate the circuit board 30 and the first telescopic cable module 201 and the second telescopic cable module 202. In this way, the two main housing walls 11 can be spaced apart in the thickness direction to accommodate the thickness direction of the first telescopic cable module 201 and the second telescopic cable module 202, and the size of the housing 10 can be unified with the size of the first telescopic cable module 201 and the second telescopic cable module 202, thereby saving space inside the housing 10 and making the arrangement of components more compact. The above method also enables the first telescopic cable module 201 and the second telescopic cable module 202 to extend the connector 24 from the side of the housing 10, thereby making it convenient for the user to take the connector 24 from the side of the charging device 1 for charging, which helps to improve the efficiency of use.

[0044] In some embodiments, the circuit board 30 further includes an output control board 34 connected to the main circuit board 31. The output control board 34 is disposed on one side edge of the main circuit board 31, and the output control board 34 and the adapter board 32 are disposed on two opposite edges of the main circuit board 31. The output control board 34 may be a control board with multiple interfaces, or it may be a screen that can output relevant information during the charging process. In other words, the output control board 34 can output current or information. The output control board 34 and the adapter board 32 are spaced apart, allowing them to independently occupy space on opposite sides of the main circuit board 31, thus reducing mutual interference between the two boards.

[0045] Combination Figure 5 and Figure 6 In some embodiments, the spacing direction of the two adapter plates 32 is parallel to the extension direction of the output control plate 34, and the first telescopic cable module 201 and the second telescopic cable module 202 are disposed between the output control plate 34 and the adapter plates 32. Optionally, the winding axis is perpendicular to the main surface of the main circuit board 31. In this way, the main circuit board 31, the adapter plates 32, and the output control plate 34 can form an accommodating space for the first telescopic cable module 201 and the second telescopic cable module 202. The main circuit board 31 requires a large area. By setting the main circuit board 31 perpendicular to the winding axis, the main circuit board 31 can correspond to the larger first main sidewall 211 and second main sidewall 212 of the first telescopic cable module 201 and the second telescopic cable module 202, so that the main circuit board 31 and the first telescopic cable module 201 and the second telescopic cable module 202 can partially overlap in the direction of the winding axis, realizing the sharing of part of the space. The adapter plate 32 and the output plate require a small area and can be positioned on opposite sides of the first telescopic cable module 201 and the second telescopic cable module 202, corresponding to the peripheral sidewalls 213 of the first telescopic cable module 201 and the second telescopic cable module 202. This allows the adapter plate 32 and the output control plate 34 to share space in the thickness direction with the first telescopic cable module 201 and the second telescopic cable module 202. This method improves the space utilization of the charging device 1.

[0046] Furthermore, the spacing direction of the first telescopic cable module 201 and the second telescopic cable module 202 is parallel to the spacing direction of the two adapter plates 32. This allows the positions of the two adapter plates 32 to correspond to the positions of the first telescopic cable module 201 and the second telescopic cable module 202, thereby reducing the possibility of cable crossings during routing and facilitating the connection of the first telescopic cable module 201, the second telescopic cable module 202, and the adapter plates 32.

[0047] Combination Figures 1 to 3In some embodiments, the charging device 1 further includes a support assembly 50, which is mounted outside the housing 10. The support assembly 50 includes a support 51 and a connector 52, one end of which is rotatably connected to the housing 10, and the other end is rotatably connected to the support 51. By providing the support 51, the charging device 1 can function as a support for electronic devices. By providing the connector 52 to be rotatably connected to the support 51 and the housing 10, the support 51 can be folded in or unfolded by rotation. Optionally, the housing 10 is provided with a receiving groove, in which the support 51 is received after being folded in.

[0048] In some embodiments, a wireless charging module is provided within the bracket 51, and the wireless charging module is electrically connected to the circuit board 30 via a connector 52. Conductive components or wiring may be provided within the connector 52 to electrically connect the circuit board 30 to the wireless charging module. The wireless charging module enables the bracket assembly 50 to support electronic devices while simultaneously charging electronic devices with wireless charging capabilities, thus providing multiple different charging methods and further facilitating user charging of electronic devices.

[0049] The above are merely embodiments of this application and do not limit the patent scope of this application.
