[0048] A charging device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0049] Reference Figure 1 The present invention aims to provide an embodiment of a charging device.

[0050] In this embodiment, the charging device includes a main body 100, which is hollow and can accommodate various charging components. The main body 100 has various openings, at which a plug 240 and a charging connector 110 are located. The plug 240 facilitates connection to a power source, while the charging connector 110 connects to the electrical device to meet charging needs.

[0051] In some specific embodiments of this utility model, the main body 100 can be provided with a charging interface, which facilitates the connection of a detachable wire, is easy to use, and meets different usage needs.

[0052] In this embodiment, the main body 100 may include two housings 260, which cooperate to form a mounting cavity for mounting the components of the charging device.

[0053] In some specific embodiments of this utility model, the main body 100 can include a shell 260 and a cover 270, so that the shell 260 has a larger volume and the cover 270 has a smaller volume, reducing manufacturing difficulty and making it easier to identify and avoid incorrect assembly.

[0054] In some specific embodiments of this utility model, the housing 260 and the cover 270 can be separated in the thickness direction of the charging device, so that the housing 260 is more open, which facilitates the arrangement and assembly of various components and reduces the manufacturing difficulty.

[0055] In this embodiment, the main outer contour of the body 100 can be rectangular, such as... Figure 1 The square shape shown makes it easy to store and carry.

[0056] In this embodiment, the main body 100 can be a cube with rounded corners on its edges to create a smooth transition, reduce sharp edges, and prevent scratching other items.

[0057] In this embodiment, the edge of the housing 260 can have a notch, and the notch and the cover 270 are used to install the side cover 140. The side cover 140 is used to form a storage cavity for accommodating the charging connector 110, which reduces the manufacturing difficulty.

[0058] In this embodiment, the edge of the side cover 140 can be provided with a plug-in edge, which is arranged almost around the outer contour of the side cover 140. Correspondingly, the notch of the housing 260 and the notch of the cover 270 are provided with slots. The plug-in edge and the slot cooperate to fix the side cover 140, reducing the installation difficulty.

[0059] In this embodiment of the charging device, the charging device is equipped with two wires. One end of the wires is connected to the main body 100, and the other end of the wires is provided with a charging connector 110. The charging connector 110 can be in the form of a Type-C interface or the like, to adapt to the settings of the product to be charged.

[0060] Since this utility model aims to solve the defect of setting storage slots 120 for each of the two charging connectors 110, in some specific embodiments of this utility model, a single wire can be configured with two or more charging connectors 110 to reduce application limitations.

[0061] In some specific embodiments of this utility model, the number of wires can be more than two to meet different usage needs.

[0062] In this embodiment, the main body 100 has a storage groove 120 for accommodating at least two charging connectors 110. The charging connectors 110 located in the storage groove 120 are arranged side by side. A fixing component is provided at the bottom of the storage groove 120 for fixing the charging connectors 110.

[0063] In summary, by setting a fixing component, the present invention can fix the charging connectors 110 one by one to the storage slots 120, so that the charging connectors 110 are neatly arranged in the storage slots 120. There is no need to set a separate storage slot 120 for each charging connector 110, which can reduce the space occupied, reduce or even avoid the increase in the thickness of the charging device, reduce the space occupied, and make the structure of the charging device more compact and convenient to carry.

[0064] This invention, by setting a fixing component at the bottom of the storage slot 120, avoids occupying the space around the side wall of the storage slot 120, thus helping to keep the thickness of the charging device within a small range.

[0065] By setting a fixing component at the bottom of the storage slot 120, this utility model also ensures that the use and storage of each charging connector 110 do not affect each other.

[0066] This invention stores two charging connectors 110 side by side. Therefore, when each of the two charging connectors 110 is connected to a wire, the lengths of the two wires can be equal and relatively long, which makes full use of the internal space of the charging device and reduces usage differences.

[0067] In this invention, long exposed wires can be avoided, which helps protect the wires and prevents them from being damaged.

[0068] Meanwhile, this invention can also reduce the area occupied by the fixed charging connector 110, allowing more structures to be arranged on the main body 100, such as more charging output interfaces and rotating and retractable plugs 240, giving the charging device more advantages.

[0069] In some specific embodiments of this utility model, the storage slot 120 can be located on the end face of the main body 100, that is, located on... Figure 1 The large flat surface of the housing 260 or cover 270 shown is for use in products such as power banks.

[0070] Since the storage slot 120 can accommodate more than two charging connectors 110 in a smaller volume, the size of the large flat surface of the housing 260 or cover 270 can also be reduced.

[0071] In this embodiment, the storage slot 120 is disposed on the side or narrow side of the main body 100, that is... Figure 1 The position shown also allows the main body 100 to accommodate longer wires, and also allows the wires to be arranged in a retractable form to meet the needs of long-distance charging, such as when using a mobile phone while charging, or when the socket is far from the product to be charged.

[0072] Reference Figure 2 and Figure 3 In some specific embodiments of this utility model, the main body 100 may include a side cover 140, the side cover 140 having a first opening 160 and an annular wall 170 arranged along the edge of the first opening 160, the annular wall 170 forming the side wall of the storage groove 120, thereby making the part forming the storage groove 120 independent of the shell 260 and the cover 270 of the main body 100, which is convenient to manufacture and reduces the manufacturing difficulty.

[0073] In some specific embodiments of this utility model, the main body 100 may include a side shell 150, which is used to form the bottom of the storage groove 120. The side shell 150 and the annular wall 170 cooperate to form the storage groove 120. A wire inlet / outlet 180 is provided at the junction of the annular wall 170 and the side shell 150, thereby reducing the manufacturing difficulty of forming the wire inlet / outlet 180.

[0074] Reference Figure 4In some specific embodiments of this utility model, the side shell 150 can be provided with an installation groove 190 on the side facing away from the storage groove 120. The installation groove 190 is used to install the fixing component. Therefore, when the fixing component includes the first magnetic member 130, the first magnetic member 130 can fix the charging connector 110 and prevent the charging connector 110 from taking away the first magnetic member 130 during use.

[0075] In some specific embodiments of this utility model, the side shell 150 can have frame-shaped ribs for forming the mounting groove 190, which overcomes the influence of the rounded corners around the side shell 150 on the depth of the mounting groove 190, thus ensuring the depth of the mounting groove 190. At the same time, it enhances the strength of the side shell 150 and makes it less prone to deformation.

[0076] In some specific embodiments of this utility model, the frame-shaped rib can be made into a square frame shape to match the shape of the first magnetic suction member 130.

[0077] In some specific embodiments of this utility model, the side cover 140 may be provided with a second opening 161, which is used to form a charging output interface, thereby facilitating the insertion of a separate wire into the charging output interface, without being limited to using the charging wire provided with the charging device, and making it easy to use universally.

[0078] In order to install the side shell 150 onto the side cover 140, in some specific embodiments of this utility model, one side of the side shell 150 may be provided with a side insertion part 200 that is inserted into the annular wall 170, and the other side of the side shell 150 may be provided with a mounting ear 210. The mounting ear 210 is provided with a mounting hole 220, which accommodates a screw connected to the annular wall 170. The space around the mounting ear 210 is used to form a wire inlet / outlet 180.

[0079] That is, the side insert 200 is inserted into the edge of the annular wall 170, and then the side shell 150 is rotated so that the mounting ear 210 fits against the side shell 150. Then, the screw passes through the mounting hole 220 and connects to the side cover 140, so that the side shell 150 can be fixed to the side cover 140.

[0080] During production and assembly, the wires can be placed in the wire inlet / outlet 180 first, and then the side shell 150 and the side cover 140 can be fixed.

[0081] In this embodiment, the side insertion part 200 can include a plug and a slot, allowing for multi-position insertion and improving installation reliability.

[0082] In some specific embodiments of this utility model, an insertion structure 230 can be provided between the side shell 150 and the annular wall 170, which inserts into the storage groove 120 in the vertical direction, so that the side shell 150 and the side cover 140 are accurately positioned and not easily misaligned.

[0083] In this embodiment, the vertically inserted plug structure 230 is located on one pair of sides, while the side plug portion 200 and the mounting ear 210 are located on the other pair of sides.

[0084] In some specific embodiments of this utility model, the annular wall 170 can have a transition angle for forming the bottom of the groove, which is equivalent to locally increasing the descendant of the annular wall 170, making it convenient to form a structure that cooperates with the side insertion part 200, and making it convenient to form an insertion structure 230 for vertical insertion, so as to facilitate installation.

[0085] For the fixing component, the fixing component can be a Velcro, with one part of the Velcro located at the bottom of the storage slot 120 and the other part located at the charging connector 110. Therefore, when the charging connector 110 is placed in the storage slot 120, the Velcro fixes the charging connector 110 to the storage slot 120.

[0086] In some specific embodiments of this utility model, the fixing component may include a limiting post erected in the storage groove 120, and the charging connector 110 has a socket that is fitted onto the limiting post. At the same time, due to the lateral pulling of the wire, the charging connector 110 is fixed on the limiting post.

[0087] In some specific embodiments of this utility model, the fixing component may include a suction cup, which is used to adsorb and fix the charging connector 110.

[0088] In some specific embodiments of this utility model, the fixing component may include a first magnetic element 130, which uses the magnetic principle to fix the charging connector 110, reducing the design difficulty and making it easy to implement.

[0089] In some specific embodiments of this utility model, the number of first magnetic suction members 130 can correspond to the number of charging connectors 110, and the first magnetic suction members 130 can be arranged side by side so that the charging connectors 110 can be placed side by side to avoid overlapping and affecting each other.

[0090] In some specific embodiments of this utility model, the charging connector 110 may have a second magnetic member corresponding to the first magnetic member 130. The first magnetic member 130 and the second magnetic member cooperate to fix the charging connector 110, thereby improving the reliability of fixing the charging connector 110 and making the position of the charging connector 110 more accurate.

[0091] In some specific embodiments of this utility model, the first magnetic member 130 can have a length direction, and the length direction of the first magnetic member 130 is arranged along the extension direction of the charging connector 110 to enhance the ability to fix the charging connector 110. At the same time, it avoids increasing the radial dimension of the charging connector 110 and avoids increasing the space occupied.

[0092] Reference Figure 1 and Figure 5 In this embodiment, the main body 100 has a plug 240, and the plug 240 and the storage slot 120 are located on opposite sides of the main body 100. Inserting the plug 240 and taking out the charging connector 110 do not affect each other, making it convenient to use.

[0093] In some specific embodiments of this utility model, the plug 240 may include rotatable prongs 250 for storage, so as to prevent the prongs 250 from scratching the items.

[0094] In some specific embodiments of this utility model, the pin 250 can be located at the corner of the outer contour of the main body 100, making full use of the existing space without affecting the arrangement of other components.

[0095] In this embodiment, the edge of the housing 260 has a mounting notch 280, which and the cover 270 are fitted together to mount the plug 240.

[0096] In this embodiment, the mounting notch 280 and the cover 270 have slots, which secure the plug 240 by plugging in, reducing the use of screws and simplifying the structure.

[0097] In this embodiment, the housing 260 and the cover 270 are also fixed by plugging. Positioning holes and positioning posts are provided between the housing 260 and the cover 270 to ensure accurate installation.

[0098] In some specific embodiments of this utility model, the plug 240 may include a base 290 and a decorative cover 300, and a rotating shaft 310 located between the base 290 and the decorative cover 300. The base 290 is located inside the main body 100, the decorative cover 300 is exposed to the outside of the main body 100, the pin 250 is connected to the end of the rotating shaft 310, the radial outer surface of the rotating shaft 310 is provided with a conductive part for connecting the pin 250, and the base 290 is provided with a conductive spring 320 for abutting the conductive part.

[0099] The base 290 and the decorative cover 300 are installed together, and one or both of the base 290 and the decorative cover 300 are installed on the main body 100, reducing manufacturing difficulty.

[0100] In this embodiment, the base 290 is provided with a recess, which limits and positions the pivot 310, preventing the pivot 310 from moving arbitrarily. A screw is provided between the base 290 and the decorative cover 300 for reliable fastening. The head of the screw is located in the base 290, which can prevent the screw from being exposed and prevent accidental disassembly.

[0101] During use, the current flows through the pin 250, conductive part and conductive spring 320 to the transformer components inside the charging device, and is converted into current and voltage that meet the usage requirements.

[0102] When the pin 250 is folded, the conductive spring 320 has an arc-shaped arm that can limit the conductive part, so that the pin 250 remains folded and avoids accidental rotation.

[0103] When pin 250 is upright, the arc-shaped arm is flexible and can continuously contact the conductive part, ensuring smooth current flow.

[0104] Reference Figure 6 and Figure 7 The charging device may include a wire connected to the charging connector 110, a reel 330 for winding the wire, a coil spring for rotating the reel 330 to wind the wire, and an inner housing assembly for housing the wire, the reel 330, and the coil spring.

[0105] Therefore, the spring force will cause the wheel core 330 to rotate, thus retrieving the pulled-out wire.

[0106] In this embodiment, there are two inner shell components to accommodate the two wires. At the same time, the inner shell components share some space, which reduces the space occupied and saves materials.

[0107] For ease of use, the wheel core 330 is provided with an axial telescopic control mechanism for controlling the extension and retraction of the conductor.

[0108] The telescopic control mechanism includes a balance wheel 340 that is rotatably connected to the inner shell assembly, and the balance wheel 340 is provided with an eccentric column 350.

[0109] When the wheel core 330 rotates, the wheel core 330 will abut against the limiting post, causing the balance wheel 340 to rotate. In turn, the limiting post will block the rotation of the limiting wheel, or the limiting post will no longer obstruct the rotation of the wheel core 330.

[0110] On the wheel core 330, there is also a set of rails for the sliding of the eccentric column 350.

[0111] The track assembly may include an inner arc track 360 and an outer arc track 370, which are fitted together on the end face of the wheel core 330. A control post 380 is provided between the start and end points of the inner arc track 360 and the outer arc track 370. A guide cone 390 is provided on one side of the control post 380. The guide cone 390 is used to guide the eccentric post 350 into the outer arc track 370 or the inner arc track 360. The guide cone 390 is used to enable the wheel core 330 to rotate continuously. A limiting recess 400 is provided on the other side of the control post 380. The limiting recess 400 is used to keep the wheel core 330 stationary to control the length of the wire pulled out.

[0112] The working principle is as follows:

[0113] When the conductor is stationary, the charging connector 110 is engaged at the conductor inlet / outlet 180, and the limiting post may be located anywhere on the outer arc track 370 or the inner arc track 360.

[0114] When the wheel core 330 rotates, the limiting post may be located anywhere on the outer arc track 370 or the inner arc track 360.

[0115] Pull the wire outwards. Figure 7 As indicated by the arrow, rotating the wheel core 330 more than one revolution will change the position of the limiting post relative to the center of the balance wheel 340. The limiting post will be located on the side of the center of the balance wheel 340 along the direction of the wire pull-out.

[0116] After the wire is released, the wheel core 330 will rotate in the opposite direction, causing the limit post to approach the junction of the outer arc track 370 and the inner arc track 360. The limit post will return to the limit recess 400 of the control post 380 and cause the limit post to rotate around the center of the balance wheel 340. The limit post is located on the side of the center of the balance wheel 340 facing away from the direction of wire pulling out. Then, the wheel core 330 stops rotating.

[0117] When the length is stretched again to be greater than one revolution of the wheel core, the above motion will repeat, so that the length of the wire pulled out can be maintained.

[0118] When the length of the stretch is less than one revolution of the wheel core 330, the limit post will be located on the side of the center of the balance wheel 340 close to the center of the wheel core 330, and will not switch to the side of the center of the balance wheel 340 along the direction of the wire pull-out. Therefore, the limit post will enter the inner arc track 360.

[0119] At this point, after the wire is released, the coil spring will always exert a clockwise force on the wheel core 330, which is opposite to the direction in which the wire is pulled out. The wheel core 330 will continue to rotate clockwise until the wire is completely retracted.

[0120] Although the accompanying drawings show only one embodiment of the telescopic control mechanism, other existing technologies can also be used to meet different telescopic control needs.

[0121] In some specific embodiments of this utility model, a coil spring mounting port 410 can be provided on the other end face of the wheel core 330, so that the rotation control of the wheel core 330 and the coil spring mounting are separate and do not affect each other.

[0122] In some specific embodiments of this utility model, the end face of the wheel core 330 may be provided with a power-conducting component 420, which is used to conduct electricity to the wire.

[0123] In some specific embodiments of this utility model, the power-conducting component 420 can be located inside the inner arc-shaped track 360, making reasonable use of space and reducing the difficulty of arrangement.

[0124] In some specific embodiments of this utility model, the energizing component 420 can be located on the outside of the outer arc track 370, or the energizing component 420 can be located on the other end face of the wheel core 330, but the installation of the coil spring and the coordinated arrangement of other components need to be considered.

[0125] In some specific embodiments of this utility model, the energized component 420 may include a plurality of conductive rails and a plurality of conductive contacts 430 for abutting against the plurality of conductive rails. The conductive rails and the plurality of conductive contacts 430 are arranged in a ring around the rotation center of the wheel core 330. One of the conductive rails and the conductive contacts 430 is disposed in the wheel core 330, and the other of the conductive rails and the conductive contacts 430 is disposed in the inner shell component.

[0126] Therefore, when the wheel core 330 rotates, that is, when the extension wire is extended, the conductive contact 430 can continuously contact the conductive rail, avoiding interruption of electrical conduction or data communication and not affecting use.

[0127] In some specific embodiments of this utility model, the power-conducting component 420 may include a follower circuit board disposed on the wheel core 330 and a fixed circuit board disposed on the inner shell component. The follower circuit board is used to set one of the conductive rail and the conductive contact 430, and the fixed circuit board is used to set the other of the conductive rail and the conductive contact 430.

[0128] In other words, the conductive rails and conductive contacts 430 are integrated on different circuit boards, which facilitates modular assembly and reduces manufacturing difficulty.

[0129] In some specific embodiments of this utility model, the conductive contacts 430 may include a number of contact groups arranged in a ring around the rotation center of the wheel core 330. The contact groups include a grounding pin, two data communication pins, a channel configuration pin, and a power supply pin.

[0130] The ground pin can be abbreviated or simplified as GND, the two data communication pins can be abbreviated or simplified as D+ and D-, the channel configuration pin can be abbreviated or simplified as CC, which is used for insertion detection, identification of positive and negative insertion, negotiation between two ports to establish DFP and UFP identities, etc., and the power supply pin can be abbreviated or simplified as VBUS (VCC), which meets the setting requirements such as charging voltage.
