Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0031] Please see Figures 1 to 5 This utility model provides a charging device 10, including a charging body 12 and a base 14 located at the bottom of the charging body 12. The charging body 12 is used to charge electronic devices, and the base 14 serves to support the charging body 12. The specific method by which the charging body 12 charges electronic devices is not limited; it can be wired charging or wireless charging. Moreover, the charging body 12 can be a charging device with its own power supply, such as a power bank, or it can be a charging device that requires an external power source.

[0032] The charging unit 12 includes a main shell 16 and at least one retractable cable module 18 mounted on the main shell 16. The main shell 16 is located at the bottom to support the main shell 16 and the retractable cable module 18. The retractable cable module 18 can be used to connect to an external power source or to connect to an electronic device to be charged. The cable of the retractable cable module 18 has a telescopic function. During use, the cable of the retractable cable module 18 can be pulled out and kept at a corresponding length as needed. When not in use, the cable of the retractable cable module 18 can be retracted into the main shell 16 and stored inside the main shell 16.

[0033] The main body shell 16 is detachably connected to the base 14. The base 14 has a connecting part 20 for fixing to an external object on the side away from the main body shell 16. Because the base 14 and the main body shell 16 are detachably connected, the charging body 12 can be used together with the base 14, or it can be used separately from the base 14. When the charging device 10 is fixed to an external object, the charging body 12 and the base 14 can be assembled together, and the base 14 can be fixed to the external object through the connecting part 20. This reduces the risk of the charging device 10 separating from the external object under external force, thereby enhancing the stability of the charging device 10 during use. When users need to charge in other scenarios, they can separate the charging body 12 from the base 14, carry the charging body 12 to the corresponding scenario, and use the charging body 12 for charging, while the base 14 remains connected to the external object. There is no need to take the base 14 with them, so there is no need to separate the base 14 from the external object. This makes it convenient for users to use in different scenarios, and the connection strength between the base 14 and the external object will not be affected by using it in different scenarios. Moreover, during the process of separating the base 14 from the charging body 12, the base 14 remains fixedly connected to the external object, which makes it convenient for users to perform the separation operation.

[0034] The specific type of the connecting part 20 is not limited and can be set according to the situation of the external object. For example, when the external object is a relatively smooth tabletop, the connecting part 20 can be an adhesive or a suction cup, and fixed to the external object by adhesive or adsorption. When the connecting part 20 is an adhesive, it is preferred to be an adhesive with high adhesion and tearability, such as pressure-sensitive adhesive. When the external object is a metal part, the connecting part 20 can also be a magnetic part, and fixed to the external object by magnetic attraction.

[0035] The specific method by which the main shell 16 and the base 14 form a detachable connection is not limited. It can be formed by connecting parts such as bolts, by connecting structures such as snap-fit ​​structures, or by magnetic attraction.

[0036] In one embodiment, the main shell 16 and the base 14 are magnetically connected to form a detachable connection. Optionally, the main shell 16 is provided with a first magnetic element 22, and the base 14 is provided with a second magnetic element 24. The first magnetic element 22 and the second magnetic element 24 are magnetically connected to form a detachable connection between the main shell 16 and the base 14. The detachable connection between the main shell 16 and the base 14 via magnetic attraction simplifies the connection and separation process, making it convenient for users. Furthermore, the connection strength between the base 14 and the main shell 16 is not affected by repeated disassembly and reassembly.

[0037] Magnetic components refer to elements that can generate a magnetic field themselves, or elements that can be magnetized by an external magnetic field to generate a magnetic field. In this application, the first magnetic component 22 and the second magnetic component 24 can both be magnets, or one can be a magnet and the other can be a metal component that can be magnetically attracted to the magnet. In an optional example, the first magnetic component 22 is a metal component, such as an iron sheet, and the second magnetic component 24 is a magnet. The magnet and the metal component are magnetically attracted to each other to connect the main body shell 16 and the base 14 together. Compared with the solution where both the first magnetic component 22 and the second magnetic component 24 are magnets, the magnetic attraction between the magnet and the metal component is relatively small, which can reduce the difficulty of separating the charging body 12 and the base 14, and at the same time reduce the electromagnetic interference between the first magnetic component 22 and the internal electrical components of the main body shell 16.

[0038] The first magnetic component 22 is located inside the main body shell 16, and the second magnetic component 24 is located inside the base 14, so as to avoid the first magnetic component 22 and the second magnetic component 24 being exposed.

[0039] The main body shell 16 has a first receiving groove 30 and a pressure plate 32 covering the first receiving groove 30. The first receiving groove 30 is located on the inner surface of the bottom of the main body shell 16. The first magnetic component 22 is located in the first receiving groove 30, which reduces the space occupied by the first magnetic component 22 in the main body shell 16, thus reducing the overall volume of the main body shell 16. The pressure plate 32 is connected to the main body shell 16, for example, by screws, to press the first magnetic component 22 tightly into the first receiving groove 30, preventing the first magnetic component 22 from exiting from the first receiving groove 30 or from shaking and deviating from its preset position within the first receiving groove 30, thereby affecting the magnetic attraction effect with the base 14.

[0040] The base 14 has a second receiving groove 34 on the side away from the main shell 16. The second magnetic component 24 is located in the second receiving groove 34 to reduce the space occupied by the second magnetic component 24 in the base 14, which helps to reduce the overall volume of the base 14. The connecting part 20 is located on the side of the base 14 away from the main shell 16 and covers the second receiving groove 34 to press the second magnetic component 24 tightly in the second receiving groove 34, preventing the second magnetic component 24 from coming out of the second receiving groove 34 or from shaking in the second receiving groove 34 and shifting to a preset position, thereby affecting the magnetic attraction effect with the main shell 16.

[0041] Understandably, the pressure plate 32 presses the first magnetic element 22 into the first receiving groove 30. This can be done either by directly pressing the first magnetic element 22 into the first receiving groove 30, or by indirectly pressing the first magnetic element 22 into the first receiving groove 30 using an intermediate member between the pressure plate 32 and the first magnetic element 22. Similarly, the connecting part 20 can also directly press the second magnetic element 24 into the second receiving groove 34, or by indirectly pressing the second magnetic element 24 into the second receiving groove 34 using an intermediate member between the connecting part 20 and the second magnetic element 24.

[0042] In one embodiment, the position of the charging body 12 relative to the base 14 is adjustable along the circumference of the base 14, so that during use, the user can adjust the relative position of the charging body 12 to adjust it to the corresponding position, without having to adjust the position of the charging device 10 by adjusting the position of the base 14. The relative position of the charging body 12 can be adjusted independently, which is convenient for the user to adjust the position of the charging body 12 for use when the base 14 is fixed to an external object.

[0043] The specific method for adjusting the position of the charging body 12 is not limited. For example, the charging body 12 can be separated from the base 14 first, and then the charging body 12 can be adjusted to the corresponding position before connecting the charging body 12 to the base 14. Alternatively, the charging body 12 can be rotated relative to the base 14 while the charging body 12 is connected to the base 14 to achieve the effect of adjusting the position of the charging body 12.

[0044] In an optional example, the main body shell 16 and the base 14 are detachably connected by magnetic attraction between the first magnetic element 22 and the second magnetic element 24, while also allowing the main body shell 16 and the base 14 to rotate. The charging body 12 can be adjusted relative to the base 14 by rotating it. The charging body 12 does not need to be separated from the base 14 during the adjustment process, which is convenient for users.

[0045] The bottom of the main body shell 16 is provided with a limiting groove 36, and the base 14 is at least partially housed in the limiting groove 36. The main body shell 16 and the base 14 are magnetically engaged, so that the base 14 and the limiting groove 36 are rotatably and detachably engaged. That is, the base 14 can rotate within the limiting groove 36 and can also be removed from the limiting groove 36 to separate from the main body shell 16. The cross-sectional shape of the base 14 is circular. Housed in the limiting groove 36, the base 14 does not affect the rotation of the charging body 12 relative to the base 14. At the same time, it can limit the charging body 12 in the lateral direction, preventing the charging body 12 from moving relative to the base 14 in the lateral direction and separating from the base 14, thereby enhancing the stability of the charging body 12 and the base 14 in the assembled state.

[0046] When the charging body 12 and the base 14 are assembled together, the base 14 is fixed to the external object through the connecting part 20. The charging body 12 is located above the base 14. The charging body 12, the base 14 and the external object are arranged vertically. The direction perpendicular to the vertical is the horizontal main body shell 16. It can be separated from the base 14 vertically. It forms a limiting effect in the horizontal direction through the limiting groove 36. It can rotate relative to the base 14 in the circumferential direction.

[0047] In one embodiment, the main body shell 16 is provided with a first positioning structure (not shown) and the base 14 is provided with a second positioning structure (not shown). The first positioning structure and the second positioning structure cooperate to position the charging body 12 in the corresponding position, reducing the risk of the charging body 12 rotating relative to the base 14 due to misoperation.

[0048] The number of at least one of the first positioning structure and the second positioning structure is multiple. The multiple first positioning structures and / or second positioning structures are arranged at intervals along the circumference of the base 14. By cooperating the first positioning structures and the second positioning structures at different positions, the charging body 12 can be positioned at multiple different positions, thereby enhancing the stability of the charging body 12 at multiple corresponding positions.

[0049] The specific forms of the first and second positioning structures are not limited. They can be achieved by rotating the main body shell 16 relative to the base 14 to make the first and second positioning structures at different positions engage. Alternatively, the main body shell 16 can be separated from the base 14, the position of the main body shell 16 can be adjusted, and then the main body shell 16 can be fixed to the base 14. The first and second positioning structures can then re-engage to position the main body shell 16 at that position. For example, both the first and second positioning structures can be magnetic structures, forming a positioning effect through magnetic attraction. Alternatively, one of them can be an elastic positioning element and the other can be a positioning hole. The positioning effect is formed when the elastic positioning element is inserted into the positioning hole and released when it is removed from the positioning hole. Alternatively, the first and second positioning structures can also be toothed structures, achieving a positioning effect through the meshing of the teeth.

[0050] In an optional example, the first positioning structure and the second positioning structure are respectively a positioning protrusion and a positioning groove. The positioning protrusion has a certain elasticity. For example, the positioning protrusion can be set on an elastic element such as an elastic arm or a spring, so that the positioning protrusion can be inserted into the positioning groove to form a positioning effect when the main body shell 16 rotates relative to the base 14, or withdraw from the positioning groove to release the positioning effect.

[0051] In another example, the main body shell 16 is separated from the base 14, and then its position is adjusted. When the main body shell 16 is separated from the base 14, the first positioning structure and the second positioning structure separate, and at this time, the first positioning structure and the second positioning structure do not affect the adjustment of the position of the main body shell 16. When the main body shell 16 is connected to the base 14, the first positioning structure and the second positioning structure cooperate with each other to position the main body shell 16 at that position and restrict the rotation of the main body shell 16 relative to the base. In this embodiment, the first positioning structure and the second positioning structure can be meshing gear teeth, and the gear teeth are arranged circumferentially along the base 14.

[0052] In one embodiment, the main body shell 16 includes a bottom end 38 near the base 14, a top end 40 opposite to the bottom end 38, and a surrounding wall 42 between the bottom end 38 and the top end 40. A first magnetic element 22 is installed on the bottom end 38 of the main body shell 16. The direction from the bottom end 38 to the top end 40 is vertical. The top end 40 and the bottom end 38 are respectively located at the two ends of the surrounding wall 42 in the vertical direction. The telescopic cable module 18 includes a telescopic cable and a telescopic cable connector 44 located at one end of the telescopic cable. The telescopic cable connector 44 protrudes out of the outer side of the surrounding wall 42, so that when the charging device 10 is fixed on the table for use, the side of the charging body 12 from which the telescopic cable connector 44 protrudes can face the user's position, so that the telescopic cable connector 44 faces the user, making it convenient for the user to pull the telescopic cable outward and making it convenient for the user to use.

[0053] In an alternative example, the enclosure 42 has a square cross-section and is composed of four end-to-end sidewalls, with the telescopic connector 44 protruding from the outside of one of the sidewalls.

[0054] The main body shell 16 is recessed on the outer side of the enclosure wall 42 to form a first storage portion 46 for accommodating the telescopic cable connector 44. Optionally, one side wall of the enclosure wall 42 is provided with a through-hole (not shown) and the first storage portion 46 located on the outer side of the side wall and communicating with the through-hole. The telescopic cable of the telescopic cable module 18 passes through the through-hole, and the telescopic cable connector 44 can be bent at the connection between the telescopic cable connector 44 and the telescopic cable to be stored in the first storage portion 46. When the charging body 12 is not in use, the telescopic cable of the telescopic cable module 18 can be stored inside the main body shell 16 and the telescopic cable connector 44 can be stored in the first storage portion 46 to reduce the overall volume of the charging body 12 when not in use, making it convenient to carry and store. When in use, the side of the charging body 12 with the first storage portion 46 can be facing the user, making it convenient for the user to take out the telescopic cable connector 44 from the first storage portion 46 and pull the telescopic cable outward.

[0055] Understandably, in order to enhance the stability of the telescopic cable connector 44 when it is stored in the first storage part 46, magnetic elements can be provided at the positions of the telescopic cable connector 44 and the enclosure 42 corresponding to the first storage part 46, so that the telescopic cable connector 44 forms a magnetic attraction effect when it is stored in the first storage part 46, thereby enhancing the stability. Alternatively, the telescopic cable connector 44 can be made to have an interference fit with the first storage part 46, or a blocking part can be provided in the first storage part 46 to prevent the telescopic cable connector 44 from retracting. Anything that can enhance the stability of the telescopic cable connector 44 in the stored state is acceptable.

[0056] The charging body 12 also includes a wireless charging module 48, which is located at the top 40 of the main body shell 16 and electrically connected to the retractable cable module 18. The wireless charging module 48 includes a circuit board and a wireless charging coil connected to the circuit board, and the retractable cable module 18 is electrically connected to the circuit board. By providing the wireless charging module 48 on the main body shell 16, the charging body 12 has a wireless charging function, allowing charging of electronic devices via the wireless charging module 48. The wireless charging module 48 is mounted at the top 40 of the main body shell 16, allowing the top 40 of the charging body 12 to hold the electronic device to be charged. The retractable cable connector 44 of the retractable cable module 18 extends outward from the outer side of the enclosure 42. The electronic device and the retractable cable connector 44 are located on different sides of the main body shell 16, preventing the electronic device from interfering with the extension and retraction of the retractable cable.

[0057] Optionally, when the charging body 12 charges the electronic device wirelessly, it can do so by setting a power source inside the main body shell 16 of the charging body 12, connecting the power source to the wireless charging module 48, and then using the power source to charge the electronic device. Alternatively, it can be done by connecting the charging body 12 to an external power source to charge the electronic device. The connection between the charging body 12 and the external power source can be made through the retractable cable module 18 or through other power supply cables 50.

[0058] In this embodiment, the charging body 12 also includes a power supply line 50. The power supply line 50 and the retractable cable module 18 are electrically connected to the wireless charging module 48. The power supply line 50 is used to connect to an external power source, and the retractable cable module 18 is used to connect to electronic devices. This allows the charging body 12 to have both wired and wireless charging functions. In other words, the charging body 12 can charge electronic devices through the retractable cable module 18 or through the wireless charging module 48. Users can choose the appropriate charging method according to their actual situation, making it convenient for users to use.

[0059] The power supply line 50 includes a power supply line connector 52 protruding from the outside of the enclosure 42. The power supply line connector 52 and the telescopic line connector 44 are located on opposite sides of the enclosure 42, that is, the power supply line connector 52 and the telescopic line connector 44 protrude from the outside of opposite sides of the enclosure 42 in two opposite directions to prevent the power supply line 50 and the telescopic line from interfering with each other.

[0060] In an optional example, the wireless charging module 48 is used to charge a smartwatch. The enclosure 42 consists of four side walls connected end to end. The power supply connector 52 and the retractable cable connector 44 protrude from the outer sides of two opposite side walls. During the charging process, the watch face is placed on the top 40 of the charging body 12, so that it corresponds to the wireless charging module 48. The two watch straps of the smartwatch are placed on the outer sides of the other two side walls to avoid interference between the watch straps and the power supply cable 50 and the retractable cable during the charging process.

[0061] In other embodiments, the charging device may not include a power supply cable. In this case, a power supply interface can be provided on the charging body, and this interface can be electrically connected to both the retractable cable module and the wireless charging module. The charging body is then electrically connected to an external power source through this power supply interface. The power supply interface and the retractable cable connector are located on opposite sides of the enclosure to prevent interference between the external wires electrically connected to the power supply interface and between the retractable cable and the watch strap during charging.

[0062] The charging device 10 also includes a storage member 54 connected to the main housing 16. One end of the storage member 54 protrudes from the outside of the enclosure 42 and extends away from the enclosure 42. The end of the storage member 54 away from the enclosure 42 is provided with a second storage portion 56, in which the power cord connector 52 is stored. The power cord 50 and the storage member 54 cooperate to form a ring structure. When the charging body 12 is not in use, the power cord connector 52 can be stored in the second storage portion 56 to prevent the power cord 50 from becoming too messy. Moreover, when the power cord connector 52 is stored in the second storage portion 56, the power cord 50 and the storage member 54 form a ring structure, allowing the user to carry the charging body 12 in their hand or hang it on an external object through the ring structure.

[0063] There are two power supply cables 50, which are connected to the wireless charging module 48 respectively. The two power supply cables 50 are located on the same side of the storage component 54. The storage component 54 has a second storage part 56 on the side closest to the power supply cable 50 and the side furthest from the enclosure 42. The second storage part 56 closest to the power supply cable 50 is located above the other second storage part 56. The connector of the power supply cable 50 closest to the storage component 54 is stored in the upper second storage part 56, and the power supply cable connector 52 of the other power supply cable 50 is stored in the lower second storage part 56 to prevent the two power supply cables 50 from crossing after the two power supply cable connectors 52 are stored in the corresponding second storage parts 56 respectively.

[0064] Understandably, the two power supply connectors 52 can be of the same type or of different types, in order to connect to power supplies or charging heads with different types of interfaces.

[0065] The storage component 54 is provided with a magnetic suction component at one end away from the enclosure 42. The magnetic suction component is provided in correspondence with the second storage part 56. The power cord connector 52 is also provided with a magnetic suction component. When the power cord 50 plug is stored in the second storage part 56, the magnetic suction component on the storage component 54 and the magnetic suction component in the power cord connector 52 magnetically engage to enhance the stability of the power cord 50 plug when stored in the second storage part 56.
