Description

Charging kit

[0001] This application claims priority to Chinese Patent Application No. 202410702466X, filed on May 31, 2024, entitled “Charging Kit”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of charging device technology, and more particularly to a charging kit. Background Technology

[0003] Different regions have different regulations regarding plugs and sockets, so plugs from different regions are not interchangeable. Since charger plugs are usually not removable, chargers are often only compatible with a single region. If a user travels to a different region, they will need to carry an adapter to connect the charger to a local socket.

[0004] However, when the converter and charger are combined, they are usually quite bulky and inconvenient to use. Summary of the Invention

[0005] This application provides a charging kit that allows the converter and charger to be combined in a relatively compact manner.

[0006] This application provides a charging kit, which includes a charger body, a first conversion module, and a second conversion module. The charger body includes a housing, a rotating shaft, and a main plug. The rotating shaft is rotatably mounted on the housing. The main plug is connected to the rotating shaft and can rotate synchronously with the rotating shaft. The main plug has a first position and a second position in the rotation direction. The first conversion module has a first plug. The second conversion module has a second plug. When the main plug is in the first position, the first conversion module is plugged into the main plug and the main plug is electrically connected to the first plug. When the main plug is in the second position, the second conversion module is plugged into the main plug and the main plug is electrically connected to the second plug. The first conversion module and the second conversion module have different national standard types.

[0007] Based on the charging kit of this application embodiment, the main plug can rotate relative to the housing. When used with different conversion modules, the main plug can rotate to a suitable angle for conversion modules of different shapes, so as to facilitate the insertion and engagement with different conversion modules at a suitable angle, so that the conversion module and the charger body are relatively compact after combination.

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] As is well known, there are currently multiple plug standards in the world, such as the Chinese standard (GB), the American standard (US standard), the European standard (EU standard), the British standard (British standard), and the Japanese standard (JP standard). Different standards have different plug shapes and are therefore not interchangeable. The plug that comes with the charger can only be used in a specific region; users need to carry an adapter when traveling to different regions.

[0026] As shown in Figure 1, a first aspect of this application provides a charging kit 100, which includes a charger body 110, a first conversion module 120, and a second conversion module 130. It should be noted that only two conversion modules are shown in Figure 1; more conversion modules can be added as needed to accommodate more regions.

[0027] The charger body 110 has a rectification function, which can rectify AC power into DC power to charge electronic devices. For example, the charger body 110 can charge mobile phones, laptops, tablets, headphones, power banks, etc. The charger's output interface type can, for example, be USB-A, USB-C, etc., or it can be a non-standard round port, square port, etc.

[0028] As shown in Figures 2 and 3, the charger body 110 includes a housing 111, a rotating shaft 112, and main plugs 113. The housing 111 can be made of plastic. Plastic is lightweight, which makes the charger body 110 lighter. Plastic also has good insulation properties, which makes the charger body 110 safer. In addition, plastic has a low cost, which can reduce production costs.

[0029] The rotating shaft 112 is rotatably mounted on the housing 111 so that the main pin 113 can rotate relative to the housing 111. For example, the housing 111 has a rotating hole or rotating groove, and the rotating shaft 112 rotatably engages with the rotating hole or rotating groove, thereby simplifying the rotational engagement structure between the housing 111 and the rotating shaft 112. Alternatively, the rotating shaft 112 and the housing 111 are connected via a bearing, with the rotating shaft 112 connected to the inner ring of the bearing and the housing 111 connected to the outer ring of the bearing, to reduce rotational resistance.

[0030] The main pin 113 can be plugged into a compatible socket for electrical connection. The main pin 113 is connected to and rotates synchronously with the pivot 112, allowing adjustment of its position relative to the housing 111. For example, the main pin 113 can have a first position (as shown in Figure 2) and a second position (as shown in Figure 3) in the rotation direction, adapting to different usage scenarios. For instance, in the first position, the main pin 113 is folded relative to the housing 111, making it easy to carry and less likely to scratch other items. In the second position, the main pin 113 is unfolded relative to the housing 111, allowing it to be plugged into a compatible socket during use. Alternatively, when the main plug 113 is in the first or second position, the main plug 113 is in an unfolded state relative to the housing 111, so that the charger body 110 can be plugged into the socket in different postures to avoid other plugs on the socket.

[0031] As shown in Figure 4, the first conversion module 120 is detachably connected to the charger body 110. The first conversion module 120 can be connected to a compatible socket, allowing the charger body 110 to be plugged into other types of sockets via the first conversion module 120. Specifically, the first conversion module 120 has a first pin 121, which is of a different type from the main pin 113. When the main pin 113 is in the first position, the first conversion module 120 can be plugged into the main pin 113, and the main pin 113 is electrically connected to the first pin 121.

[0032] As shown in Figure 5, the second conversion module 130 is detachably connected to the charger body 110. The second conversion module 130 can be connected to a compatible socket, allowing the charger body 110 to be plugged into other types of sockets via the second conversion module 130. Specifically, the second conversion module 130 has a second pin 131, which is of a different type than the main pin 113 and the first pin 121. When the main pin 113 is in the second position, the second conversion module 130 can be plugged into the main pin 113, and the main pin 113 and the second pin 131 are electrically connected. The first conversion module 120 and the second conversion module 130 are of different national standard types. For example, the main pin 113 is a Chinese standard pin, the first pin 121 is a British standard pin, and the second pin 131 is a European standard pin.

[0033] Because the shapes of different conversion modules vary considerably, the optimal insertion direction between different conversion modules and the charger body 110 is not the same. Therefore, if each conversion module is inserted into the main pin 113 in the same direction, some conversion modules may result in a larger volume or irregular shape after being combined with the charger body 110, thus affecting usability. In this application, the main pin 113 can rotate relative to the housing 111. When used with different conversion modules, the main pin 113 can rotate to a suitable angle for different shaped conversion modules, facilitating insertion into different conversion modules at appropriate angles, resulting in a more compact combination of the conversion module and the charger body 110.

[0034] It should be noted that the charger body 110 also includes a rectifier module, which is located inside the housing 111 and is electrically connected to the main plug 113. The main plug 113 can be plugged into the socket and conduct AC power in the socket. The rectifier module is used to rectify AC power into DC power.

[0035] As shown in Figures 6 and 7, in some embodiments, the rotating shaft 112 is provided with a guide surface 112a and a first limiting groove 112b, and the opening of the first limiting groove 112b is connected to the guide surface 112a.

[0036] As shown in Figures 8 and 9, the charger body 110 also includes a push switch 114 and a first elastic member 115. The push switch 114 includes a switch body 1141 and a first limiting protrusion 1142 connected to the switch body 1141. The switch body 1141 is movably connected to the housing 111. For example, the middle part of the switch body 1141 is hinged to the housing 111. Pressing one end of the switch body 1141 causes the other end of the switch body 1141 to tilt upwards, thereby moving the first limiting protrusion 1142. Alternatively, the switch body 1141 is slidably connected to the housing 111. By pushing the switch body 1141, the switch body 1141 causes the first limiting protrusion 1142 to move.

[0037] The first elastic element 115 is connected between the housing 111 and the switch body 1141. The first elastic element 115 applies force to the switch body 1141, causing the first limiting protrusion 1142 to tend to press against the guide surface 112a. The first elastic element 115 can be, for example, a spring sheet, a coil spring, a torsion spring, an elastic rib, etc.

[0038] When the main pin 113 rotates from the first position to the second position, the first elastic element 115 causes the first limiting protrusion 1142 to press against the guide surface 112a. Just before the main pin 113 reaches the second position, the first limiting protrusion 1142 slides from the guide surface 112a into the first limiting groove 112b. When the main pin 113 is in the second position, the first limiting protrusion 1142 engages with the first limiting groove 112b to restrict the rotation of the shaft 112. By locking the shaft 112, rotation of the main pin 113 during insertion can be prevented, improving the stability of the insertion process.

[0039] It should be noted that the guide surface 112a can be a plane, an inclined surface, or a curved surface. The guide surface 112a and the first limiting groove 112b can be disposed on the end face of the rotating shaft 112. In this case, the first limiting protrusion 1142 moves along the axial direction of the rotating shaft 112, thereby achieving locking or unlocking. Alternatively, the guide surface 112a and the first limiting groove 112b can be disposed on the outer peripheral surface of the rotating shaft 112. In this case, the first limiting protrusion 1142 moves along the radial direction of the rotating shaft 112, thereby achieving locking or unlocking. Optionally, the groove opening of the first limiting groove 112b and the guide surface 112a have an arc transition, so that the first limiting protrusion 1142 can smoothly move from the guide surface 112a to the first limiting groove 112b.

[0040] As shown in Figure 6, in some embodiments, the guide surface 112a and the first limiting groove 112b are both disposed on the end face of the rotating shaft 112. The guide surface 112a extends circumferentially along the rotating shaft 112 and is arranged at an angle. The guide surface 112a has a first end 112c and a second end 112d in the circumferential direction of the rotating shaft 112. The second end 112d protrudes more in the axial direction of the rotating shaft 112 than the first end 112c. The groove opening of the first limiting groove 112b is connected to the second end 112d. When the first limiting protrusion 1142 releases from the first limiting groove 112b, the first elastic member 115 causes the first limiting protrusion 1142 to press against the guide surface 112a. Since the second end 112d protrudes more than the first end 112c, the rotating shaft 112 rotates relative to the first limiting protrusion 1142, so that the rotating shaft 112 rotates from the second end 112d abutting against the first limiting protrusion 1142 to the first end 112c abutting against the first limiting protrusion 1142, thereby enabling the main pin 113 to automatically spring back to the first position.

[0041] Optionally, the end face of the rotating shaft 112 is provided with a protrusion 1121, which is located at the first end 112c. When the first limiting protrusion 1142 moves to the first end 112c, the first limiting protrusion 1142 abuts against the protrusion 1121, and the protrusion 1121 restricts the rotating shaft 112 from continuing to rotate, so that the rotating shaft 112 can only rotate between the first position and the second position.

[0042] As shown in Figures 8 and 9, in some embodiments, the charger body 110 further includes a second elastic element 116. The second elastic element 116 is connected between the rotating shaft 112 and the housing 111. The elastic element applies force to the rotating shaft 112 to cause the main plug 113 to tend to rotate to a first position. During the process of the main plug 113 rotating from the first position to the second position, the second elastic element 116 stores force. The second elastic element 116 can be exemplarily a sheet spring, a coil spring, a torsion spring, an elastic rib, etc.

[0043] For example, when the main pin 113 is in the first position, the second elastic element 116 is in a stretched state, thereby providing a certain limiting effect to the rotating shaft 112, preventing the rotating shaft 112 from rotating arbitrarily and ensuring good stability. When the main pin 113 is subjected to an external force, the main pin 113 rotates from the first position to the second position, and the second elastic element 116 is stretched. When the external force disappears or the first limiting protrusion 1142 releases the limiting state from the first limiting groove 112b, the second elastic element 116 restores a certain deformation and drives the rotating shaft 112 to rotate, so that the main pin 113 rotates to the first position.

[0044] Alternatively, when the main pin 113 is in the first position, the second elastic element 116 is compressed, thus providing a certain limiting effect to the rotating shaft 112, preventing it from rotating arbitrarily and ensuring good stability. When the main pin 113 is subjected to external force, the second elastic element 116 is compressed when the main pin 113 rotates from the first position to the second position. When the external force disappears or the first limiting protrusion 1142 is unlocked from the first limiting groove 112b, the second elastic element 116 restores its deformation and drives the rotating shaft 112 to rotate, causing the main pin 113 to rotate back to the first position.

[0045] In some embodiments, when the conversion module is combined with the charger body 110, it can be fixed by a limiting structure to ensure good integrity between the conversion module and the charger body 110, making it less prone to separation during plugging and unplugging. For example, as shown in Figures 9 and 10, the push switch 114 further includes a second limiting protrusion 1143 connected to the switch body 1141. Optionally, the extending direction of the second limiting protrusion 1143 is the same as the extending direction of the first limiting protrusion 1142, thereby allowing simultaneous control of the locking states of both the first limiting protrusion 1142 and the second limiting protrusion 1143 when the switch body 1141 is pressed, making it more convenient to use.

[0046] As shown in Figure 11, the first conversion module 120 also includes a first housing 122 and a first limiting member 123 connected to the first housing 122. A first plug 121 is disposed on the first housing 122, and a first socket 122a is provided on the first housing 122. When the first socket 122a is plugged into the main plug 113, the first limiting member 123 can engage with the second limiting protrusion 1143. Therefore, when the first socket 122a is plugged into the main plug 113, the first limiting member 123 and the second limiting protrusion 1143 engage, making the first conversion module 120 and the charger body 110 more stably connected. The first conversion module 120 and the charger body 110 are not easily separated during use, and the safety is better.

[0047] As shown in Figure 12, the second conversion module 130 also includes a second housing 132 and a second limiting member 133 connected to the second housing 132. A second pin 131 is disposed on the second housing 132, and a second socket 132a is provided on the second housing 132. When the second socket 132a is inserted into the main pin 113, the second limiting member 133 can engage with the second limiting protrusion 1143. Therefore, when the second socket 132a is inserted into the main pin 113, the second limiting member 133 and the second limiting protrusion 1143 engage, making the connection between the second conversion module 130 and the charger body 110 relatively stable. The second conversion module 130 and the charger body 110 are not easily separated during use, resulting in better safety.

[0048] As shown in Figures 6 and 9, in some embodiments, the circumferential surface of the rotating shaft 112 is provided with a groove 112e that is radially recessed along the rotating shaft 112. The opening of the groove 112e faces the same direction as the extension direction of the main pin 113. The groove 112e is provided on the rotating shaft 112 and can rotate with the rotating shaft 112, thereby cooperating with the limiting component structure of different conversion modules. Moreover, the limiting component structure of different conversion modules can have a uniform shape, reducing design and manufacturing costs. The end face of the rotating shaft 112 facing the switch body 1141 is provided with a slot 112f, which communicates with the groove 112e. The second limiting protrusion 1143 can pass through the slot 112f and extend into the groove 112e.

[0049] As shown in Figure 11, the first limiting member 123 is provided with a first limiting hole 123a arranged axially along the rotating shaft 112. When the first insertion hole 122a is inserted into the main insertion pin 113, the first limiting member 123 is inserted into the groove 112e, and the second limiting protrusion 1143 can pass through the slot 112f and pass through the first limiting hole 123a. The first limiting member 123 can be clearance-fitted with the groove 112e, and the limiting is achieved solely by the second limiting protrusion 1143 and the first limiting hole 123a, thereby reducing the resistance when the first limiting member 123 is inserted into the groove 112e and making it easy to operate and assemble. Alternatively, the first limiting member 123 can be interference-fitted with the groove 112e, thereby providing a certain limiting resistance to enhance the strength when the charger body 110 is combined with the first conversion module 120.

[0050] It should be noted that, since the second limiting protrusion 1143 moves synchronously with the first limiting protrusion 1142, when the main pin 113 is in the first position, the first limiting protrusion 1142 abuts against the first end 112c. At this time, the second limiting protrusion 1143 extends into the groove 112e, thereby preventing the first limiting member 123 from being inserted into the groove 112e. Therefore, during the process of the first limiting member 123 being inserted into the groove 112e, the switch body 1141 needs to be pressed. When the first limiting member 123 is inserted into the groove 112e, the switch body 1141 is released, and the first elastic member 115 drives the switch body 1141 to rebound, thereby allowing the second limiting protrusion 1143 to pass through the first limiting hole 123a to achieve limiting engagement.

[0051] As shown in Figure 12, the second limiting member 133 is provided with a second limiting hole 133a arranged axially along the rotating shaft 112. When the second insertion hole 132a is inserted into the main insertion pin 113, the second limiting member 133 is inserted into the groove 112e. The switch body 1141 can drive the second limiting protrusion 1143 to move, so that the second limiting protrusion 1143 can pass through the slot 112f and pass into the second limiting hole 133a. The second limiting member 133 can be clearance-fitted with the groove 112e, relying solely on the second limiting protrusion 1143 and the second limiting hole 133a for limiting, thereby reducing the resistance when the second limiting member 133 is inserted into the groove 112e and making it easy to operate and assemble. Alternatively, the second limiting member 133 can be interference-fitted with the groove 112e, thereby providing a certain limiting resistance to enhance the strength when the charger body 110 and the second conversion module 130 are combined.

[0052] It should be noted that, since the second limiting protrusion 1143 moves synchronously with the first limiting protrusion 1142, when the main pin 113 is in the first or second position, the first limiting protrusion 1142 engages with the first limiting groove 112b. At this time, the second limiting protrusion 1143 extends into the groove 112e, thus preventing the second limiting member 133 from being inserted into the groove 112e. Therefore, during the process of inserting the second limiting member 133 into the groove 112e, the switch body 1141 needs to be pressed. When the second limiting member 133 is inserted into the groove 112e, the switch body 1141 is released, and the first elastic member 115 drives the switch body 1141 to rebound, thereby allowing the second limiting protrusion 1143 to pass through the second limiting hole 133a to achieve the limiting engagement.

[0053] As shown in Figures 9 and 10, in some embodiments, the first limiting protrusion 1142 and the second limiting protrusion 1143 are disposed at the same end of the switch body 1141, so that when the switch body 1141 is pressed, the first limiting protrusion 1142 and the second limiting protrusion 1143 can be driven to move simultaneously.

[0054] In some embodiments, the first limiting protrusion 1142 is connected to the second limiting protrusion 1143, that is, the switch body 1141, the first limiting protrusion 1142, and the second limiting protrusion 1143 are connected in pairs, thereby improving the structural strength of the switch body 1141, the first limiting protrusion 1142, and the second limiting protrusion 1143, which means that the press switch 114 has higher structural strength and a longer service life.

[0055] In some embodiments, the second limiting protrusion 1143 is cylindrical, and the first limiting hole 123a is a circular hole. The second limiting protrusion 1143 and the first limiting hole 123a are collinearly arranged with the rotating shaft 112. That is, the second limiting protrusion 1143 and the first limiting hole 123a are in a radially limited fit with the rotating shaft 112, but not in the circumferential direction of the rotating shaft 112. This allows the second limiting protrusion 1143 to rotate within the first limiting hole 123a when the rotating shaft 112 rotates. Consequently, when the first conversion module 120 is plugged into the main pin 113, the first conversion module 120 can rotate with the main pin 113 to achieve folding or unfolding. Optionally, the second limiting protrusion 1143 and the first limiting hole 123a are in a clearance fit to reduce the resistance when the rotating shaft 112 rotates.

[0056] The second limiting protrusion 1143 is cylindrical, and the second limiting hole 133a is circular. The second limiting protrusion 1143 and the second limiting hole 133a are coaxially arranged with the rotating shaft 112. That is, the second limiting protrusion 1143 and the second limiting hole 133a are radially limited but not circumferentially limited. This allows the second limiting protrusion 1143 to rotate within the second limiting hole 133a when the rotating shaft 112 rotates. Consequently, when the second conversion module 130 is inserted into the main pin 113, the second conversion module 130 can rotate with the main pin 113 to achieve folding or unfolding. Optionally, the second limiting protrusion 1143 and the second limiting hole 133a are clearance-fitted to reduce resistance during the rotation of the rotating shaft 112.

[0057] For some conversion modules, when they are engaged with the charger body 110, the main plug 113 is in the first position. When the main plug 113 is in the first position, the limiting strength of the main plug 113 in the rotation direction relies solely on the elastic force of the second elastic element 116, thus the limiting strength is limited. At this time, the conversion module may rotate with the main plug 113, thereby affecting its use.

[0058] As shown in Figures 7 and 11, in some embodiments, a first limiting part 1221 is provided on the first outer shell 122, and a second limiting part 1111 adapted to the first limiting part 1221 is provided on the shell 111. When the first insertion hole 122a is inserted and engaged with the main insertion pin 113, the first limiting part 1221 and the second limiting part 1111 engage in a limiting engagement. By engaging the first limiting part 1221 and the second limiting part 1111, the rotation of the conversion module is restricted, thereby improving the stability during use.

[0059] For example, the first limiting part 1221 can be a protrusion, and the second limiting part 1111 can be a limiting groove, thereby making the limiting structure simpler and the cost lower.

[0060] As shown in Figure 13, in some embodiments, the housing 111 has a clearance portion 111a. When the main pin 113 is in the first position, the main pin 113 is housed in the clearance portion 111a, so that the main pin 113 can be both folded and exposed outside the housing 111, facilitating insertion and engagement with the second conversion module 130. Exemplarily, the housing 111 is generally cubic in shape, and a clearance portion 111a is recessed at one corner of the housing 111.

[0061] As shown in Figure 13, when the first socket 122a is inserted into the main plug 113, the first housing 122 is at least partially accommodated in the clearance portion 111a. Since different conversion modules have different shapes, the clearance portion 111a also serves to allow for partial clearance of the conversion module, allowing the housing 111 to fit relatively tightly with the first housing 122. This results in a relatively compact structure after the first conversion module 120 and the charger body 110 are combined, making it easy to use in narrow spaces. Simultaneously, the first housing 122 can abut against two planes of the clearance portion 111a, thereby achieving limiting in at least two directions to improve the stability of the assembly. In the first position, the main plug 113 extends out from one plane of the clearance portion 111a, and the second limiting portion 1111 is located on this plane; correspondingly, the surface of the first housing 122 abutting against this plane can be provided with a first limiting portion 1221.

[0062] As shown in Figure 14, when the second socket 132a is inserted into the main socket 113, the second outer shell 132 is located outside the clearance portion 111a, so that the second outer shell 132 can be exposed outside the housing 111 as much as possible, thereby facilitating the insertion and engagement of the second socket 131 with the corresponding socket. Of course, the second outer shell 132 can also be rotated into the clearance portion 111a, thereby folding it to reduce its volume when stored.

[0063] In some embodiments, when the main pin 113 is in the first position, the extension direction of the main pin 113 is the first direction AA. When the main pin 113 is in the second position, the extension direction of the main pin 113 is the second direction BB. Optionally, the angle between the first direction AA and the second direction BB is 90 degrees. Of course, other angles are also possible and are not limited here.

[0064] As shown in Figure 13, the insertion direction of the first conversion module 120 when it is plugged into the charger body 110 is the first direction AA, and the extension direction of the first pin 121 is the first direction AA. For example, the second conversion module 130 is plugged into the main pin 113 from left to right, and the type of the first pin 121 can also be the Thai standard, Brazilian standard, Korean standard, etc.

[0065] As shown in Figure 14, the insertion direction of the second conversion module 130 when it is plugged into the charger body 110 is the second direction BB, and the extension direction of the second pin 131 is the first direction AA. For example, the second conversion module 130 is plugged into the main pin 113 from top to bottom, and the type of the second pin 131 can also be American standard, Japanese standard, etc.

[0066] Different conversion modules have different insertion directions when combined with the charger body 110, but the pins of different conversion modules face the same direction, thus conforming to the design insertion and removal direction of the charger body 110.
