Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the technical field of charging electronic equipment, and in particular to a pull-out wire module and a charging device. Background Art
[0002] Many electronic devices such as mobile phones and tablets require data cables for charging. The data cables are long and easily tangled, which brings inconvenience to use. For this reason, the prior art has developed charging devices that can retract the data cables, making it convenient for users to carry, and the data cables will not be tangled, knotted or take up space. Charging devices are usually equipped with a pull-out cable module to achieve the extension and retraction of the data cables and the electrical connection of the data cables. In the prior art, in order to meet a higher user experience, it is often necessary to make the charging device as small as possible, so the pull-out cable module is set to a small volume accordingly, so the area of the circuit board in the pull-out cable module needs to be as small as possible. However, since all the lines of the data cable are set on a rotating circuit board, the number of conductive components on the circuit board is small or the area is small, which affects the current carrying capacity and thus affects the output power of the charging device. Utility Model Content
[0003] In view of the above problems, the embodiments of the present invention provide a small-sized pull-out wire module and a charging device capable of carrying large currents.
[0004] According to one aspect of the embodiments of the present invention, there is provided a pull-out wire module, comprising:
[0005] case;
[0006] a rotating mechanism, disposed in the housing and rotating relative to the housing;
[0007] A circuit board, wherein two circuit boards are provided and located in the housing, and the two circuit boards are spaced apart and arranged on the rotating mechanism;
[0008] a data line, disposed between the two circuit boards and wound around the outside of the rotating mechanism, the data line electrically connecting the two circuit boards respectively;
[0009] A conductive component is provided in the housing, and is movably and electrically connected to the circuit board; two conductive components are provided, and the two conductive components correspond to the two circuit boards in a one-to-one manner.
[0010] In an optional manner, a conductive disk is provided on the circuit board, and the conductive disk is provided on a side of the circuit board close to the housing, and a conductive portion in contact with the conductive disk is provided on the conductive component.
[0011] In an optional manner, the conductive component includes a conductive sheet, the conductive sheet is arranged between the circuit board and the housing, and the conductive portion is protruded on the conductive sheet in a direction close to the conductive disk.
[0012] In an optional manner, the circuit board is provided with a plurality of conductive plates, the conductive assembly includes a plurality of conductive sheets, and the plurality of conductive sheets correspond one-to-one to the plurality of conductive plates.
[0013] In an optional manner, a plurality of the conductive plates are nested on the same side of the circuit board, and the plurality of the conductive plates are spaced apart; a plurality of the conductive sheets are nested on the housing, and the plurality of the conductive sheets are spaced apart.
[0014] In an optional manner, the conductive sheet is provided with a power connection portion, and the power connection portion is protruded from the conductive sheet.
[0015] In an optional manner, the pull-out wire module further includes a connector, which is connected to the power connection portion on one of the conductive components.
[0016] In an optional embodiment, the connector includes a connector body and metal pins arranged at opposite ends of the connector body, the metal pins at one end of the connector are connected to the power connection part of one of the conductive components, and the metal pins at the other end of the connector are arranged close to the power connection part of the other conductive component.
[0017] In an optional manner, the metal pin at the other end and the power connection portion of the other conductive component are arranged on the same side of the shell.
[0018] According to another aspect of the embodiment of the present utility model, a charging device is provided, which includes a charging module and the above-mentioned pull-wire module, the charging module is arranged on the outside of the shell, and the charging module is electrically connected to the two conductive components.
[0019] In this embodiment, two circuit boards are spaced apart on the rotating mechanism. The data lines are electrically connected to both circuit boards simultaneously. Each circuit board is movably connected to a conductive component, which in turn connects to the charging module. Since there are two circuit boards, the data line circuits are divided into two groups, each electrically connected to the two circuit boards. This reduces the area of the circuit boards on one side while increasing the number or area of conductive components (such as conductive discs) to carry greater current, thereby charging high-power devices. This reduces the overall size of the charging device while still being able to charge high-power devices.

DETAILED DESCRIPTION
[0027] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0028] See also Figure 1a 、 Figure 1b and Figure 2 , Figure 1a A three-dimensional diagram of an embodiment of the pull-out wire module of the present invention is shown. Figure 1b A three-dimensional diagram of another angle of the embodiment of the pull-out wire module of the utility model is shown. Figure 2 The exploded view of the internal structure of an embodiment of the present invention's cable drawing module is shown. The cable drawing module comprises a housing 1, a rotating mechanism 2, a circuit board 3, a data line 4 and a conductive component 5.
[0029] The rotating mechanism 2 is disposed in the housing 1 and rotates relative to the housing 1 , wherein the rotating mechanism 2 is fixed to the housing 1 and rotates relative to the housing 1 .
[0030] Two circuit boards 3 are provided and located in the housing 1 . The two circuit boards 3 are spaced apart on the rotating mechanism 2 and are fixedly connected to the rotating mechanism 2 . When the rotating mechanism 2 rotates, the two circuit boards 3 rotate accordingly.
[0031] The data cable 4 is positioned between the two circuit boards 3 and wound around the outside of the rotating mechanism 2. When the data cable 4 is pulled, the circuit boards 3 and the rotating mechanism 2 rotate together. In one embodiment, a space is formed between the two circuit boards 3 and the rotating mechanism 2 to accommodate the data cable 4. The two circuit boards 3 secure the data cable 4, preventing damage to the winding shape of the data cable 3. In the prior art, a housing is generally used to accommodate the data cable 4 and ensure that the data cable 4 is secure after storage. However, this embodiment cleverly utilizes two circuit boards to form a storage space, which not only increases the circuit board area but also eliminates the need for a housing, saving space and cost. Furthermore, by rotating the rotating mechanism 2, the data cable 4 can be pulled out or stored. It is understood that the rotating mechanism 2 can automatically retract to accommodate the data cable 4 using existing technology, for example, by utilizing the principle of a coil spring cooperating with a rotating shaft. It should be noted that the data cable can both transmit data and charge.
[0032] The data line 4 is electrically connected to the two circuit boards 3 respectively. Specifically, the conductive wire in the data line 4 is divided into two parts, which are connected to the two circuit boards 3 respectively. Then, the data line 4 is electrically connected to different circuit boards 3 by dividing the conductive wire into two parts. On the circuit boards 3 of the same area, the fewer the number of conductive wires in the data line 4 connected to the same circuit board 3, the greater the current that can pass through the conductive components on the circuit board 3, and the charging device can charge high-power electronic devices.
[0033] Two conductive components 5 are provided, and the two conductive components 5 are arranged in a one-to-one correspondence with the two circuit boards 3 to achieve electrical conductivity of both circuit boards 3. Specifically, the two conductive components 5 are fixed in the housing 1 and are respectively located on the side of each circuit board 3 close to the housing 1. Optionally, the two conductive components 5 can be fixed in the housing 1 by existing fixing methods such as screws or clamps.
[0034] The data line 4 is electrically connected to the two circuit boards 3, each of which is movably electrically connected to a nearby conductive component 5. It is understood that the two circuit boards 3 move as the rotating mechanism 2 rotates. During the movement of the two circuit boards 3, one circuit board 3 movably connects to the corresponding conductive component 5, and the other circuit board 3 movably connects to the corresponding conductive component 5. This allows the power supply current to flow through the charging module (not shown) and then be split to the two conductive components 5. The current from the two conductive components 5 is then conducted to the corresponding circuit boards 3. The two circuit boards 3 then conduct the current to the data line 4, which charges the electrical device. In this embodiment, since the two conductive components 5 are fixed, the rotating mechanism 2 rotates, electrically connecting the corresponding conductive components 5 through the rotating circuit boards 3, achieving rotation and ensuring that the electrical connection is maintained at any time or when rotated to any position. In addition, since there are two circuit boards 3, larger and / or more conductive components can be provided on both circuit boards 3. Larger conductive components can carry greater current, and more conductive components can provide the data line 4 with more functions.
[0035] In one embodiment, both circuit boards 3 are provided with conductive plates 31, which are located on the side of the circuit boards 3 closest to the housing 1. Both conductive components 5 are provided with conductive portions 51 that contact the corresponding conductive plates 31. After the power supply current is diverted to the conductive portions 51 on the two conductive components 5 via the charging module, the current in the conductive portions 51 is then conducted to the corresponding conductive plates 31 on the circuit boards 3. The conductive plates 31 then conduct the current to the data lines 4.
[0036] In one embodiment, the conductive component 5 includes a conductive sheet 52 disposed on the housing 1 between the circuit board 3 and the housing 1. A conductive portion protrudes from the conductive sheet 52, proximate to the conductive plate 31, and abuts against the conductive plate 31. The power supply current is diverted by the charging module to the two conductive sheets 52 on the conductive component 5 before being transferred to the conductive portion 51. The conductive portion 51 then conducts the current to the corresponding conductive plate 31 on the circuit board 3. The conductive plate 31 then conducts the current to the data line 4.
[0037] In one embodiment, each circuit board 3 includes multiple conductive plates 31, each located on the same side of the circuit board 3. The plates 31 are nested and spaced apart, with each plate 31 connected to one of the data lines 4, such as the positive or negative line. Each conductive assembly 5 also includes multiple conductive pads 52, located on the side of the assembly 5 closest to the circuit board 3. The pads 52 are also nested and spaced apart, corresponding one-to-one with the multiple conductive plates 31. It is understood that the number of conductive plates 31 on each circuit board 3 is the same as the number of conductive pads 52 on the corresponding conductive assembly 5. The position of each conductive plate 31 on the circuit board 3 corresponds to the position of the conductive pad 52 on the corresponding conductive assembly 5. For example, the conductive plates 31 and the corresponding conductive pad 52 are located on the same straight line along the height of the drawer cable module. Each conductive pad 52 is provided with a conductive portion 51, with each conductive portion 51 contacting a corresponding conductive plate 31. The conductive portion 51 protrudes from the conductive pad 52 in a direction proximal to the conductive plate 31.
[0038] Optionally, both the conductive discs 31 and the conductive sheets 52 are annular structures, with each pair of conductive discs 31 and each pair of conductive sheets 52 spaced apart. The conductive portion 51 on one annular conductive sheet 52 contacts another annular conductive disc 31. When the conductive disc 31 rotates with the circuit board 3, it is ensured that it maintains electrical connection with the conductive portion 51 at any time or when rotated to any position. It is understood that, based on actual needs, larger conductive discs 31 and / or a greater number of conductive discs 31 can be provided on the two circuit boards 3. The conductive portion 51 can be a protrusion or elastic wall on the conductive sheet 52, contacting the conductive disc 31. In other embodiments, the conductive component 5 can be a connector or an electrical pin header, which is not intended to be exclusive.
[0039] In one embodiment, the pull-out cable module further includes a connector 6, which is fixed within the housing 1. Optionally, the connector 6 can be fixed within the housing 1 by existing fixing methods such as screws or clips. One end of the connector 6 is disposed near one conductive component 5, and the other end of the connector 6 is disposed near another conductive component 5. Either end of the connector 6 is electrically connected to a conductive sheet 52 of the conductive component 5 disposed thereon. In this embodiment, the connector 6 can be used to bring the circuits corresponding to the two conductive sheets 52 distributed on both sides of the two circuit boards 3 together in the same position, facilitating electrical connection with the charging module.
[0040] In one embodiment, each conductive sheet 52 is provided with a power connection portion 53 , which is protruded from the conductive sheet 52 , for example, protruded from the conductive sheet 52 along the height direction of the pull-out wire module. The power connection portion 53 is used to connect to an external power source.
[0041] Optionally, the connector 6 includes a connector body 61 and metal pins 62. The metal pins 62 are provided at opposite ends of the connector body 61. The metal pins 62 are inserted through and fixed to the connector body 61. The metal pin 62 at one end of the connector 6 is connected to the power connection portion 53 of one of the conductive components 5. The metal pin 62 at the other end of the connector 6 is positioned adjacent to the other conductive component 5, thereby converging the circuits of the conductive components 5 at both ends onto the same side of the pull-out cable module, facilitating circuit connection.
[0042] Alternatively, if multiple conductive plates 31 are provided on each circuit board 3, and the conductive component 5 corresponding to the circuit board 3 is also provided with the same number of conductive plates 52, then multiple metal pins 62 are also provided, and the number is the same as the number of corresponding conductive plates 52. The multiple metal pins 62 are arranged at intervals on the connector body 61. One end of the multiple metal pins 62 is provided near one conductive component 5, and the other end of the multiple metal pins 62 is provided near another conductive component 5, and each metal pin 62 is electrically connected to each conductive plate 52.
[0043] Optionally, the connector 6 serves as a connecting device, and one or two connectors 6 may be provided according to actual needs. If two connectors 6 are provided, the other connector 6 is electrically connected to the conductive sheet 52 on the other conductive component 5 .
[0044] In one embodiment, the conductive sheets 52 of the two conductive components 5 are further provided with a power connection portion 53, which is protruding from the side of the conductive sheet 52 near the housing 1. The purpose of providing the power connection portion 53 is to electrically connect part of the charging module's circuit through the power connection portion 53 of its proximal conductive sheet 52, while the remaining circuit of the charging module is connected to the connector 6, which is connected to the power connection portion 53 of the distal conductive sheet 52 to achieve electrical connection. Optionally, the power connection portion 53 can be provided only on the proximal conductive sheet 52 to facilitate connection with the charging module, while the distal conductive sheet 52 can be omitted, and the connector 6 can be directly electrically connected to the distal conductive sheet 52.
[0045] In one embodiment, the metal pin 62 at the other end (i.e., the metal pin 62 not connected to the conductive component 5) and the power connection portion 53 of another conductive component 5 (i.e., the conductive component 5 not connected to the connector 6) are arranged on the same side of the shell 1, so that the lines of the two conductive components 5 at both ends are gathered on the same side of the shell 1.
[0046] Specifically, a groove is provided on the outside of the housing 1. The end of the conductive sheet 52 not connected to the connector 6 and the power connection portion 53 located near the groove both pass through the housing 1 and extend into the groove. In this embodiment, the wiring corresponding to the conductive sheet 52 is gathered into the groove through the connector 6 and the power connection portion 53, facilitating electrical connection to the charging module.
[0047] Optionally, the housing 1 includes an upper housing 11 and a lower housing 12, and the groove is provided on the outer side of the upper housing 11 or the outer side of the lower housing 12, such as Figure 1a The first groove 111 of the upper shell 11 and the second groove 121 of the lower shell 12.
[0048] Optionally, one of the two conductive components 5 is fixed to the inner side of the upper shell 11 , and the other conductive component 5 is fixed to the inner side of the lower shell 12 .
[0049] Optionally, a connecting plate (not shown) can be provided in the groove, and one end of the connector 6 is electrically connected to the charging module through the connecting plate with the power receiving portion 53. In this embodiment, by providing a connecting plate, the circuit can be further organized to facilitate electrical connection with the charging module.
[0050] Optionally, a fixed shaft (not shown in the figure) is provided in the lower shell 12, and the rotating mechanism 2 is fixed in the shell 1 through the fixed shaft.
[0051] How it works:
[0052] When the cable drawing module is not in use, the data cable 4 is wound on the rotating mechanism 2 .
[0053] During use, the user pulls out the data cable 4. During the process of pulling out the data cable 4, the rotating mechanism 2 is driven to rotate, and the two circuit boards 3 rotate along with the rotation of the rotating mechanism 2. The conductive disk 31 rotates along with the rotation of the circuit board 3. During the rotation of the conductive disk 31, the conductive sheet 52 on the two fixed conductive components 5 is always electrically connected. The charging module is electrically connected through the two conductive sheets 52, so that the current of the charging module is conducted to the data cable 4 after passing through the conductive sheet 52 and the conductive disk 31. The data cable 4 charges the external electrical device.
[0054] In this embodiment, two circuit boards 3 are spaced apart on the rotating mechanism 2. Each circuit board 3 is electrically connected to a fixed conductive component 5, and is connected to the charging module through the conductive component 5. Since two circuit boards 3 are provided, compared to the prior art method of providing only one circuit board, this embodiment can reduce the area of the circuit boards 3 while maintaining the same volume of the cable withdrawal module, thereby reducing the volume of the cable withdrawal module. At the same time, larger and / or more conductive discs 31 can be provided on the same circuit board 3. A larger conductive disc 31 can carry a larger current, thereby charging high-power electrical devices. More conductive discs 31 can also give the data cable 4 more functions.
[0055] An embodiment of the present invention further provides a charging device, which includes a charging module and the pull-out wire module in any of the above embodiments. The charging module is arranged on the outside of the shell, and the charging module is electrically connected to the two conductive components.
