[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0028] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0029] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0030] The retractable data cable assembly is a device used for charging and / or communicating with the data cable. The data cable can be retracted to change its length. The retractable data cable assembly can be built into other devices. The components for data cable retraction built into other devices can be called data cable retractable modules. It can be understood that the data cable retractable module can also be used independently of other devices, that is, the data cable retractable module is used alone, and does not have to be built into other devices.

[0031] In the relevant data cable retractable module, a spring is installed inside the device. When the retractable data cable is pulled out to a certain length, the spring is tightened under the action of external force. After the retractable data cable is used, the external force disappears, the spring automatically recovers its deformation, and the data cable is also tightened under the action of the spring's deformation recovery force. The data cable can be electrically connected inside the retractable module to achieve conductivity. This retractable module will be equipped with conductive elements to meet the normal working requirements of the data cable retractable module. However, due to the increase in the number of parts inside the retractable module, the volume of the retractable module will increase accordingly, which is not conducive to internal installation and daily carrying.

[0032] like Figure 1 As shown, the small-volume telescopic module in the embodiment of the utility model comprises: a housing 10, a winding core disk 11, a conductive component 17 and a positioning member 15. Figure 2 As shown, the housing 10 is provided with a receiving chamber 101, and the receiving chamber 101 is provided with a data line 12, a core disk 11, a conductive component 17 and a positioning component 15; the core disk 11 is provided with a first through hole 112, and the data line 12 is arranged around the core disk 11; the conductive component 17 is partially arranged in the first through hole 112 and is electrically connected to the data line 12. It can be understood that the core disk 12 is arranged in the housing 10, and the data line 12 is wound on the core disk 11. One end of the data line can be stretched, and the other end of the data line passes through the first through hole 112 and is electrically connected to the conductive component 17 arranged in the first through hole 112 to transmit an electrical signal. The positioning component 15 is slidably connected to the core disk 11 to limit the extension and retraction of the data line 12. It can be understood that one end of the positioning component 15 can contact the core disk 11 and can slide with the rotation of the core disk 11. The positioning component 15 realizes the extension and retraction positioning of the data line 12 by limiting the rotation of the core disk 11. The conductive component 17 and the positioning member 15 are located on the same side of the target central axis plane of the accommodating cavity 101, and the target central axis plane is perpendicular to the central axis Z axis in the thickness direction of the telescopic module and bisects the accommodating cavity 101. In other words, the positioning member 15 and the conductive component 17 are located on the same side of the winding core disk, and the two share space.

[0033] Among them, the telescopic module in the embodiment of the utility model is a unidirectionally stretched telescopic module, the data line 12 is wound on the core disk 11, one end of the data line 12 can be stretched, and the other end is fixed in the middle of the core disk 11 and cannot be stretched, and is electrically connected to the conductive component 17 to transmit electrical signals. During the stretching of the data line 12, the core disk 11 rotates with the stretching of the data line 12, and the positioning member 15 slidably connected to the core disk 11 moves on the core disk 11 with the rotation of the core disk 11, restricting the rotation of the core disk 11, thereby playing a positioning role. Since the conductive component 17 and the positioning component 15 are located on the same side of the target mid-axis surface of the accommodating cavity 101, it can be regarded as that the conductive component 17 and the positioning member 15 share space, which reduces the thickness of the telescopic module in the Z-axis direction.

[0034] In addition, it should be emphasized that in the small-volume telescopic module provided in the embodiment of the present utility model, the small volume refers to: the size satisfies the thickness H≤15mm and the volume V≤21000mm. 3 .

[0035] The embodiment of the utility model arranges the second conductive member and the positioning member in the same space, thereby reducing the thickness of the telescopic module. While meeting the normal working requirements of the telescopic module, the volume of the telescopic module can be reduced, making it easier to be built in and carry, thereby improving the user experience during use.

[0036] In some embodiments, Figure 1 As shown, the housing 10 includes: a first plane 104 and a second plane 105, wherein the first plane 104 is located in the area where the inner wall surface of the housing 10 contacts the conductive component 17, and the second plane 105 is located in the area where the inner wall surface of the housing 10 contacts the positioning member 15. It can be understood that the conductive component 17 and the positioning member 15 share a space and are located on the same side of the target mid-axis surface of the accommodating cavity 101, the contact surface between the conductive component 17 and the housing 10 is the first plane 104, the conductive component 17 is mounted on the first plane 104, the contact surface between the positioning member 15 and the housing 10 is the second plane 105, and the positioning member 15 and the second plane 105 are rotatably connected.

[0037] Among them, Figure 2 As shown, the vertical distance from the first plane 104 to the target mid-axis plane is H1, and the vertical distance from the second plane to the target mid-axis plane is H2. The relationship between H1 and H2 satisfies the following two conditions:

[0038] First, a vertical distance H1 from the first plane 104 to the target mid-axis plane and a vertical distance H2 from the second plane to the target mid-axis plane are equal.

[0039] When H1 is equal to H2, the first plane 104 and the second plane 105 are coplanar, that is, the end surface of the conductive component 17 away from the winding core disk 11 and the end surface of the positioning member 15 away from the winding core disk 11 are coplanar. At this time, the height of the shared space between the conductive component 17 and the positioning member 15 is fully utilized, and the height of the shared space between the conductive component 17 and the positioning member 15 can be minimized.

[0040] Second, the vertical distance H1 from the first plane 104 to the target mid-axis plane is not equal to the vertical distance H2 from the second plane to the target mid-axis plane.

[0041] When H1 is not equal to H2, the first plane 104 and the second plane 105 are not coplanar. It can be understood that the end surface of the conductive component 17 away from the winding core disk 11 and the end surface of the positioning member 15 away from the winding core disk 11 are not coplanar, and the positions of the conductive component 17 and the positioning member 15 in the shared space have a certain height difference. In other words, when the conductive component 17 and the positioning member 15 are arranged on the same side of the target central axis plane of the accommodating cavity 101 and can ensure the normal operation of the conductive component 17 and the positioning member 15, the first plane 104 and the second plane 105 on the inner wall surface of the housing 10 can also be set to be non-coplanar.

[0042] The embodiment of the utility model further plans the space where the conductive component and the positioning member are located by limiting the vertical distance from the contact surface of the conductive component and the positioning member with the shell to the target central axis surface, thereby improving the utilization rate of the space and further reducing the size of the telescopic module.

[0043] In some embodiments, Figure 2 As shown, the thickness of the conductive component is greater than the thickness of the positioning member.

[0044] It can be understood that by setting the thickness of the conductive component 17 to be greater than the thickness of the positioning member 15, the positioning member 15 can be sufficiently accommodated within the space height set by the conductive component 17, so that the height of the shared space can be fully utilized to reduce the height of the telescopic shared space.

[0045] In some embodiments, Figure 3 As shown, the telescopic module further includes: a slide rail 114, and the first component 151 of the positioning member 15 is movably connected to the slide rail 114, wherein the position of the slide rail 114 is set in the following two situations:

[0046] When the slide rail 114 is disposed on the core disk 11 around the first through hole 112 , the second component 152 of the positioning member 115 is connected to the inner wall of the housing 10 .

[0047] It can be understood that the slide rail 114 is arranged on the end face of the core disk 11 close to the second side 113, and a first through hole 112 is arranged in the middle of the core disk 11. The slide rail 114 is arranged around the first through hole 112 on the outside of the conductive component 17, and the first part of the positioning member 15 is arranged on the inner wall of the shell 10. The second part of the positioning member 15 is slidably connected to the slide rail 114 in the accommodating cavity 101. During the rotation of the core disk 11, the second part of the positioning member 15 can move along the slide rail 114 to meet the positioning function of the telescopic module for the telescopic data line 12.

[0048] When the slide rail 114 is disposed on the inner wall of the housing 10 around the first through hole 112 , the second part of the positioning member 115 is connected to the winding core disk 11 .

[0049] It can be understood that the slide rail 114 is arranged on the inner wall of the shell 10, and the positioning member 115 is correspondingly arranged on the core disk 11. Since a first through hole 112 is arranged in the middle of the core disk 11, the positioning member 115 is located on the outside of the first through hole 112 on the core disk 11. The second part of the positioning member 15 is slidably connected to the slide rail 114 in the accommodating cavity 101. During the rotation of the core disk 11, the second part of the positioning member 15 can move along the slide rail 114 to meet the positioning function of the telescopic module for the telescopic data cable 12.

[0050] The embodiment of the utility model sets the slide rail at the edge of the winding core disk, which provides sufficient space for the arrangement of the conductive components, improves the utilization rate of the space where the winding core disk is located, further limits the size of the space occupied by the components, and is conducive to reducing the size of the telescopic module.

[0051] In some embodiments, Figure 4 As shown, the conductive assembly 17 includes: a column portion 131, a conductive portion 132, a flat portion 1321, a protruding portion 1322, a conductive track portion 141 and a connecting portion 142; the column portion 131 defines a second through hole 1311 coaxial with the first through hole 112, that is, as shown in FIG. Figure 2As shown, the column portion 131 is installed in the first through hole 112 through the second through hole 1311, so that the first through hole 1311 is installed coaxially with the second through hole 112. The extension direction of the conductive portion 132 is perpendicular to the axial direction of the second through hole 1311, and extends from one side of the second through hole 1311 to the other side; it can be understood that the conductive portion 132 extends radially along both sides of the second through hole 1311, and one end of the conductive portion 132 is electrically connected to the data line 12 to transmit the electrical signal in the data line 12. Among them, the two ends of the extension direction of the conductive portion 132 are connected to the core disk 11 to rotate with the core disk 11. It can be understood that the conductive component 17 is partially arranged in the first through hole 112 in the core disk 11, and the conductive portion 132 is connected to the core disk 11. During the rotation of the core disk 11, the conductive portion 132 rotates around the Z axis around the column portion 131 along with the core disk 11. The flat plate portion 1321 extends from one end to the other end in the extension direction of the conductive portion 132; the raised portion 1322 is connected to one side of the flat plate portion 1321; along the extension direction of the conductive portion 132, a plurality of raised portions 1322 are arranged at intervals, that is, the flat plate portion 1321 serves as a base in the conductive portion 132, and a plurality of grooves are arranged at intervals along the extension direction of the flat plate portion 1321, and a plurality of raised portions 1322 are fixedly installed in the grooves of the flat plate portion 1321. The conductive track portion 141 is provided with a plurality of tracks corresponding to the raised portions 1322 so that the raised portions 1322 can move along the tracks 141; it can be understood that the conductive track portion 141 is provided on the end surface of the conductive component 17 facing the raised portions 1322, and the conductive track portion 141 is composed of a plurality of annular tracks arranged around the Z axis, and the conductive track portion 141 corresponds one by one to the plurality of raised portions 1322. The connecting portion 142 extends from the conductive track portion 141 to the edge of the winding core disk 11, such as Figure 5 As shown, the connecting portion 142 is provided with a conductive terminal 143 at one end close to the edge of the winding core disk 11 to connect to the power supply. It can be understood that the connecting portion 142 is provided at the edge of the conductive track portion 141, extending from a position close to the conductive track portion 141 to a direction away from the conductive track portion 141, and at the same time, a conductive terminal 143 is provided at the edge of the connecting portion 142, and the data line can be connected to an external power supply through the conductive terminal. Among them, the protrusion 1322 protrudes from the column portion 131 in the axial direction of the second through hole 12 to keep at least one protrusion 1322 electrically connected to the conductive track portion 141. (See Figure 5 ). It can be understood that in the Z-axis direction, the protrusion 1322 has a protrusion 1323 close to the conductive track portion 141, and the protrusion portion exceeds the edge of the lower end of the column portion 131 along the Z-axis direction, so that the protrusion 1322 can fully contact the conductive track portion to maintain electrical connection.

[0052] The column part 131 is coaxially installed with the core disk 11 through the second through hole 1311, and the conductive part 132 extends to the edge of the first through hole 112 and is connected to the core disk 11. During the rotation of the core disk 11, the conductive part 132 rotates around the Z axis with the core disk 11. During the rotation of the conductive part 132, the various components of the conductive component 17 always maintain contact, ensuring that the electrical signal in the data line 12 can be stably transmitted. Figure 5 As shown, the conductive component 17 conducts electricity through the protruding portion 1322 in the conductive portion 132. The protruding portion 1322 has a protrusion close to the side of the conductive track portion 141, so that the protruding portion 1322 contacts the conductive track portion 141 for electrical connection; the end of the protruding portion 1322 away from the conductive track portion 141 is a plane, and the data line 12 is connected to the end of the conductive component 17 close to the flat portion. The flat portion 1321 of the electrical signal in the data line 12 is transmitted to the protruding portion 1322 on the conductive portion 132, and the protruding portion 1322 is electrically connected to the conductive track portion. The electrical signal is transmitted to the conductive track portion 141 through the conductive portion 132 to meet the requirements of electrical signal transmission in the data line 12. Further, a plurality of protruding portions 1322 are arranged at intervals on the conductive portion 132 to ensure stable transmission of the electrical signal. During the rotation of the conductive part 132, the multiple protrusions 1322 move along the corresponding multiple conductive track parts 141, and the protrusions 1322 and the conductive guide rail parts 141 always maintain contact during the movement. The connecting part 142 extends from the conductive track part 141 to the edge of the core disk 11, and the conductive terminal 143 is arranged on the end surface of the connecting part 142 away from the core disk 11 and is located at the edge of the connecting part 142, so that the external power supply can be connected to the conductive component 17 through the conductive terminal 143. It should be noted that the conductive terminal 143 can also be connected to a USB interface, etc., not limited to a power supply, as long as it is a device that can transmit electrical signals.

[0053] The embodiment of the utility model arranges part of the conductive component inside the winding core disk so that the conductive part can rotate coaxially with the winding core disk, and arranges a plurality of protrusions on the conductive part, as well as a conductive track part corresponding to the plurality of protrusions one by one. An electrical connection is formed by the contact between the protrusion and the conductive track part to transmit the electrical signal of the data line. During the rotation of the conductive part, the protrusion can rotate stably along the track, and at the same time, one end of the protrusion is raised beyond the column part to ensure that the conductive part is in full contact with the conductive track part, thereby preventing poor contact inside the conductive component, further optimizing the stability of the electrical connection, improving the working performance of the telescopic module, and improving product quality and user experience.

[0054] In some embodiments, Figure 2 As shown, on the end surface of the core disk 11 where the slide rail 114 is provided, the positioning member 15 is located between the conductive component 17 and the edge of the core disk 11 .

[0055] It can be understood that the positioning member 15 is connected to the slide rail 114. Since the slide rail 114 is set on the edge of the core disk 11, the position of the positioning member 15 needs to be set in accordance with the position of the slide rail 114. Since the position of the conductive track portion 141 needs to be set corresponding to the conductive portion 132, the conductive track portion 141 is coaxially arranged with the first through hole 111. At this time, the positioning member 15 is arranged outside the conductive track portion 141, that is, the positioning member 15 is located between the conductive component 17 and the edge of the core disk 11.

[0056] The embodiment of the utility model arranges the positioning member within the edge of the conductive component and the winding core disk, thereby improving the utilization rate of the space, reducing the length of the telescopic module in the direction perpendicular to the Z axis, and further reducing the volume of the device.

[0057] In some embodiments, Figure 7 As shown, the housing 10 has a first opening 102 to extend the data line 12 , and a second opening 103 to expose the conductive terminal 143 of the conductive component 17 for connecting to a power source.

[0058] It can be understood that the data cable 12 wound on the core disk 11 extends out of the shell 10 through the first opening 102, and the data cable 12 can be retracted through the first opening 102; the second opening 103 is set on the contact surface between the connecting part 142 and the shell 10, and the conductive terminal contacts the outside world through the second opening 103 to facilitate the connection of an external power supply.

[0059] The embodiment of the utility model embeds the positioning member and the second conductive member into the inner wall of the shell. The positioning member and the second conductive member share space with the shell as well, thus saving space in the accommodating cavity inside the shell and further reducing the size of the telescopic module.

[0060] The present utility model also provides a small-volume telescopic module. Figure 1 As shown, the telescopic module includes: a winding core disk 11, a first conductive member 13, a second conductive member 14 and a positioning member 15. Figure 2As shown, the data cable 12 is arranged in a circle on the first side 113 of the core disk 11, and the core disk 11 is provided with a first through hole 112, that is, the Z-axis can be considered as the symmetry axis of the telescopic module as a whole. When the Z-axis direction is from top to bottom, the first side 111 is located on the upper side of the core disk 11 along the Z-axis direction, and the data cable 12 is wound around the first side 111 on the core disk 11 with the Z-axis as the center. A first through hole 112 is also provided inside the core disk 11, and the first through hole 112 passes through the core disk 11 along the Z-axis direction. The first conductive member 13 is arranged to be electrically connected to the data line 12. It can be understood that the data line 2 is wound around the first side 111, one end of the data line can be stretched, and the other end of the data line passes through the first through hole 112 and is electrically connected to the first conductive member 13 arranged in the first through hole 112 to transmit an electrical signal; the second conductive member 14 is arranged on the second side 114 of the core disk 11, the second side 114 is opposite to the first side 113, and the second conductive member 14 is electrically connected to the first conductive member 13. It can be understood that along the Z-axis direction, the core disk 11 has a second side 112 arranged opposite to the first side 111, and when the Z-axis extends from top to bottom, the second side 112 is located below the core disk 11 along the Z-axis direction, and the second conductive member 14 is arranged on the second side 112 and is electrically connected to the first conductive member 13 arranged in the first through hole 112; the positioning member is arranged on the second side 114 of the core disk 11, and the positioning member 15 is slidably connected to the core disk 11 to limit the extension and retraction of the data line 13. It can be understood that, as Figure 3 As shown, the positioning member 15 has a first component 151 extending toward the slide rail 114. The positioning member 15 and the second conductive member 14 are arranged on the same side. The positioning member 15 is connected to the slide rail 114 through the first component 151. During the rotation of the core disk 11, the first component 151 moves along the slide rail 114. Every time the core disk 11 rotates one circle, the positioning member 15 can be engaged with the slide rail 114 to limit the rotation of the core disk 11, thereby controlling the stretched length of the data line 12.

[0061] Among them, Figure 5As shown, the first conductive member 13, the second conductive member 14 and the third conductive member 16 all belong to the conductive component 17. The data line 12 is wound on the first side 111 of the winding core disk, one end of the data line 12 can be stretched, and the other end is fixed in the middle of the winding core disk 11 and cannot be stretched. Further, the fixed end of the data line is connected to the third conductive member 16, and the first conductive member is electrically connected to the third conductive member, that is, the data line 12 is electrically connected to the first conductive member 13 through the third conductive member 16. The electrical signal in the data line 12 is transmitted to the first conductive member 11 through the third conductive member 16. Since the first conductive member 13 and the second conductive member 14 are electrically connected, the electrical signal is further transmitted from the first conductive member 13 to the second conductive member 13, and the conductive terminal 143 is arranged on the second conductive member 14. The electrical signal in the data line 12 can be connected to the external device through the second conductive member 14, thereby completing the transmission of the electrical signal.

[0062] The embodiment of the utility model arranges the second conductive member and the positioning member on the same side of the winding core disk, so that the second conductive member and the positioning member can be arranged together in a space at the same height, which is beneficial to reducing the thickness of the telescopic module. While meeting the normal working requirements of the telescopic module, the volume of the telescopic module can be reduced, which facilitates the internal integration of the telescopic module and improves the user experience during use.
