Description

[0002] Many electronic devices such as mobile phones and tablets require data cables for charging. Data cables are long and easy to get tangled, which brings inconvenience to use. For this reason, the prior art has developed charging devices that can retract data cables, making it convenient for users to carry, and the data cables will not get tangled, knotted, or take up space. For charging devices with retractable data cables, the lines from the circuit board are set on the shaft of the rotating component, and the data cables are connected to the lines on the shaft, so that the data cables can be electrically connected to the circuit board and can be rotated and stored on the rotating component. However, the inventors found during research and development that since there are multiple lines, when multiple lines are set on the shaft, they need to be spaced a certain distance apart. This distance causes the rotating component to occupy a larger three-dimensional space, resulting in the entire charging device being large in size and inconvenient to carry.

DETAILED DESCRIPTION

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] See also Figure 1-Figure 3 , Figure 1 and Figure 2 The three-dimensional diagram of the charging device embodiment of the utility model at different angles is shown. Figure 3 A schematic diagram of the internal structure of part of an embodiment of a charging device of the utility model is shown, and the charging device includes: a shell 1, a circuit board assembly 2, a rotating wire-receiving mechanism 3 and a data cable 4. The circuit board assembly 2 and the rotating wire-receiving mechanism 3 are fixedly arranged in the shell 1. It can be understood that the circuit board assembly 2 and the rotating wire-receiving mechanism 3 can be fixed in the shell 1 by means of screws or clamps.

[0027] The housing 1 is provided with a power pin 11, which is electrically connected to the circuit board assembly 2 and the data line 4 respectively. The power pin 11 is inserted into a power socket, and the user device is charged through the circuit board assembly 2 and the data line 4.

[0028] Among them, Figure 1 As shown, the power pin 11 is rotatably arranged on the housing 1, and a groove is arranged on one side of the housing 1 where the power pin 11 is arranged, and the power pin 11 is partially accommodated in the groove after being retracted. The groove is arranged in this embodiment to protect the power pin 11 from being exposed when the charging device is not in use, and is convenient to carry. In addition, it is also convenient for the user to bend the power pin 11 for use.

[0029] The data line 4 is stored in the housing 1 by rotating the wire collection mechanism 3, that is, the data line 4 can be stretched out when charging the electrical device, and can be rotated and stored in the housing 1 when not in use. A plurality of annular conductive lines 21 are arranged at intervals on the circuit board assembly 2, and one end of the data line 4 is rotatably electrically connected to the annular conductive line 21 to form a surface contact. When the data line 4 is stretched or stored or stops stretching and charging, it can ensure that the data line 4 always contacts the annular conductive line 21 on the circuit board assembly 2 within a 360-degree rotation range. Compared with the existing charging device, this surface contact structure saves the space occupied by the rotating wire collection mechanism 3 due to the setting of the line, and the rotating wire collection mechanism 3 can be made smaller, thereby making the charging device smaller in size and convenient to carry.

[0030] As for the circuit board assembly 2, the circuit board assembly 2 includes an electrically connected charging circuit board 22 and a connecting board 23, the connecting board 23 is arranged in parallel with the charging circuit board 22, the connecting board 23 is arranged between the charging circuit board 22 and the rotating wire-receiving mechanism 3, the charging circuit board 22 and the connecting board 23 can be fixed in the housing 1 by means of screws or clamping, a plurality of annular conductive circuits 21 are arranged at intervals on the connecting board 23, and one end of the data line 4 is rotatably electrically connected to the annular conductive circuit on the connecting board 23. In the existing charging device, in order to facilitate the placement of the device, the two PCB boards are arranged in a vertical structure. Obviously, the vertical structure will occupy a large space, resulting in a larger volume of the charging device. The way in which the connecting board 23 is arranged in parallel with the charging circuit board 22 in this embodiment can reduce the space occupied by the PCB board, thereby making the volume of the charging device smaller.

[0031] In one embodiment, the charging circuit board 22 integrates a strong current circuit and a weak current circuit, wherein, in order to improve the safety of use, the strong current circuit is arranged at one end close to the power pin 11, and the weak current circuit is arranged at the other end away from the power pin 11. This method of integrating the strong current circuit and the weak current circuit on the same circuit board can save space compared to the existing method of setting the strong current circuit on one circuit board and the weak current circuit on another circuit board, thereby making the charging device smaller in size.

[0032] For data line 4, refer to Figure 3-Figure 4 , Figure 4 The schematic diagram of the structure of the connector of the charging device embodiment of the utility model is shown. The data line 4 includes a connector 41 and a line body (not shown in the figure). The connector 41 can be fixedly set on the rotating wire take-up machine 3 by means of screws or clamping, and the rotating wire take-up machine 3 drives the connector 41 to rotate when it rotates. A metal spring 411 is provided on the connector 41. The metal spring 411 includes a first end 4111 and a second end 4112. The first end 4111 is provided on the upper side of the connector 41 to facilitate the connection of the line body. The second end 4112 is provided on the lower side of the connector 41 to facilitate the connection of the annular conductive circuit 21, and the second end 4112 is rotatably electrically connected to the annular conductive circuit 21.

[0033] In one embodiment, see Figure 5 , Figure 5The schematic diagram of all the internal structures of the charging device embodiment of the utility model is shown. The charging device also includes a support plate 5, which can be fixed in the housing 1 by means of screws or clamps, and the charging circuit board 22 and the connecting plate 23 are respectively fixed on both sides of the support plate 5, so as to separate the charging circuit board 22 and the connecting plate 23 to meet the necessary insulation requirements and form a creepage distance to meet the safety distance requirements. In addition, the charging circuit board 22, the support plate 5, the connecting plate 23 and the rotating wire collection mechanism 3 are stacked in parallel in sequence. This parallel stacking structure can make the layout of the components more compact and minimize the space on the basis of forming the creepage distance and meeting the safety distance requirements, thereby making the volume of the charging device smaller.

[0034] Among them, the circuit board assembly 2 also includes a connector 24, and the charging circuit board 22 and the connecting board 23 are positioned and electrically connected through the connector 24. Optionally, the connector 24 includes an insulator 241 and a plurality of metal pins 242, the insulator 241 is located between the charging circuit board 22 and the connecting board 23, and the plurality of metal pins 242 are arranged on the insulator 241 at intervals. The charging circuit board 22 and the connecting board 23 are both provided with holes for the insertion of the plurality of metal pins 241, so as to realize the positioning of the charging circuit board 22 and the connecting board 23, and the plurality of metal pins 241 are perpendicular to the charging circuit board 22 and the connecting board 23 and electrically connected, so that the overall structural layout is tighter. In addition, the connector 24 can also serve as a bracket to support the charging circuit board 22 and the connecting board 23, which plays the role of eliminating part of the bracket. In order to improve safety, the connector 24 is arranged at a position away from the power pin 11 to stay away from the strong electric range of the power pin 11.

[0035] In one embodiment, the connector 24 is a pin header, through which the charging circuit board 22 and the connecting board 23 are positioned and electrically connected.

[0036] For the support plate 5, a fixed shaft 51 is arranged in the middle of the support plate 5, a first opening (not shown in the figure) is arranged in the middle of the connecting plate, the fixed shaft 51 passes through the first opening, and the rotating wire-taking mechanism 3 is rotatably fixed on the fixed shaft.

[0037] Combined with reference Figure 5 and Figure 6 , Figure 6An exploded view of the internal structure of part of the charging device embodiment of the utility model is shown. The rotating wire-taking mechanism 3 includes a turntable 31, a ring 32 and a rotating clamp 33. The turntable 31, the ring 32 and the rotating clamp 33 are all provided with a second opening (not shown in the figure) for the fixed shaft 51 to pass through. The turntable is also provided with a third opening 311. The turntable 31 and the ring 32 form a first groove for storing the wire body (not shown in the figure). The connector 41 is fixed to the lower side of the turntable 31, the first end 4111 of the metal sheet 411 is connected to the wire body through the third opening 311, and the rotating clamp 33 is fixedly clamped on the upper side of the ring 32.

[0038] In one embodiment, see Figure 2 and Figure 5 The charging device also includes a USB charging socket 6, which is electrically connected to the charging circuit board 22. This embodiment provides two charging methods. You can use a retractable data cable to charge the power device, or you can use an existing data cable to plug into the USB charging socket 6 to charge the power device, which improves the flexibility of use. Figure 2 As shown, a second groove 12 is provided on one side of the housing 1, and the connector of the data cable 4 can be accommodated in the second groove 12 after being stored, which can protect the data cable from being exposed and facilitate carrying. The USB charging socket 6 and the second groove 12 are located on the same side of the housing 1 and are arranged at intervals, so that the line of the USB charging socket 6 can be designed to be the shortest, and it is convenient for users to use either one of them, and the appearance is integrated and beautiful.

[0039] Operation principle: When the charging device is not in use, the data cable 4 is rotated and stored in the housing 1 through the rotating wire collection mechanism 3, and the retracted part of the power pin 11 is accommodated in the groove.

[0040] When in use, the user bends the power pin 11, pulls out the data line 4, inserts the power pin 11 into the power socket, and connects the data line 4 to the electrical device for charging. When the data line 4 is pulled out, the rotating wire collection mechanism 3 is driven to rotate, the turntable 31 rotates with the rotation of the rotating wire collection mechanism 3, the connector 41 rotates with the turntable 31, and the second end 4112 on the connector 41 rotates with the connector 41. During the rotation process, the second end 4112 always maintains electrical connection with the annular conductive line 21 on the connecting plate 23;

[0041] When the data line 4 stops being stretched, the rotating clamp 33 is clamped, so that the rotating wire collection mechanism 3 stops moving, and the user can stretch the data line 4 to increase the length of the stretched data line 4 (stretch it within the longest range of the data line). Regardless of the length of the stretched data line 4 and the position of the connector 41, the rotating clamp 33 can be clamped to stop the rotating wire collection mechanism 3, and the second end 4112 of the connector 41 is always electrically connected to the annular conductive circuit 21 on the connecting plate 23. When the data line 4 stops being stretched, the data line 4 is connected to an electrical device for charging.

[0042] It is understandable that the charging device can achieve automatic retraction using existing technology, for example, automatic retraction can be achieved using the principle of a tape measure.

[0043] In this embodiment, an annular conductive circuit is arranged on the circuit board assembly, and one end of the data line is rotatably electrically connected to the annular conductive circuit to form a surface contact. No matter where the data line is stretched to, it can be ensured that the data line is always in contact with the annular conductive circuit on the circuit board assembly. Compared with the existing charging device, this surface contact structure saves the space occupied by the rotating wire-receiving mechanism due to the arrangement of the circuit, and the rotating wire-receiving mechanism can be made smaller, thereby making the charging device smaller and more convenient to carry.
