Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, specifically to a telescopic cable device. Background Technology

[0002] With the increasing popularity of mobile electronic devices such as smartphones, tablets, and portable hard drives, the development of data cables for charging and data transfer is also accelerating. Retractable data cables, which allow for length adjustment as needed and automatic rewinding after use, are very convenient and widely favored by consumers.

[0003] In existing technologies, retractable data cables can use magnets to attach the connector to the target position after winding. However, there are cases where the connector cannot be accurately attached to the target position, which affects the user experience. Utility Model Content

[0004] An embodiment of this application provides a retractable cord device, including a housing, a magnetic component, a winding mechanism, a cord, and a support member. The housing includes a positioning part and a cord passage hole. The magnetic component is disposed in the housing. The winding mechanism is disposed inside the housing. The support member is disposed in the housing and located on one radial side of the winding mechanism. A limiting space is formed between the side of the support member away from the winding mechanism and the inner wall of the housing. The cord includes a cord body and a connector. The cord body is wound on the winding mechanism, and one end of the cord body extends outward from the housing through the limiting space and the cord passage hole and is connected to the connector. The connector can be housed in the positioning part. The winding mechanism is used to wind up or unwind the cord body.

[0005] The retractable cable device provided in the embodiments of this application has at least the following beneficial effects: By winding the cable onto the winding mechanism, the winding mechanism can accommodate longer cables without requiring the user to organize the cable, making it more convenient for the user. By placing a support member on the housing and located on one radial side of the winding mechanism, a limiting space is formed between the side of the support member away from the winding mechanism and the inner wall of the housing. One end of the cable passes through the limiting space and the cable hole, extending outward from the housing and connected to a connector. Thus, the support member can act as a lever to support the cable, changing the movement path of the cable when the winding mechanism winds it up. This helps the center of gravity of the connector to be closer to the positioning part, allowing the connector to be more smoothly and accurately stored in the positioning part under the action of the magnetic component, resulting in a better user experience.

[0012] Please see Figures 1 to 3 This application provides a telescopic cable device 100, which includes a housing 110, a magnetic component 130, a winding mechanism 150, a cable 170, and a support component 190.

[0013] The wire 170 includes a wire body 171 and a connector 173, which can be connected to one end of the wire body 171. The wire body 171 can be used to transmit power and / or data, and the other end of the wire body 171 can also be connected to a connector 173 or other electrical structure, as described in the following embodiments.

[0014] The connector 173 can be a Type-C connector, a Micro connector, or other connectors 173.

[0015] The housing 110 is provided with a wire hole 113, which can connect the internal space inside the housing 110 and the external space outside the housing 110.

[0016] The housing 110 includes a positioning part 111. Specifically, the positioning part 111 is provided on the outer wall of the housing 110. The positioning part 111 can be a partial outer wall surface of the housing 110, a groove formed on the outer wall of the housing 110, a protrusion on the outer wall of the housing 110, etc.

[0017] The magnetic component 130 is provided on the housing 110, and the connector 173 can be stored in the positioning part 111. Specifically, the connector 173 can be stored in the positioning part 111 under the action of the magnetic component 130, which helps to prevent the connector 173 from shaking.

[0018] As an example, connector 173 may include a magnetic metal shell, magnetic element 130 may be a magnet, and connector 173 may be housed in positioning part 111 under the magnetic force of magnetic element 130.

[0019] The winding mechanism 150 is located inside the housing 110, specifically, the winding mechanism 150 is rotatably located inside the housing 110. The cable 171 is wound onto the winding mechanism 150, which is used to wind or unwind the cable 171. Thus, the winding mechanism 150 can accommodate longer cables 171 without requiring the user to organize the cable 171, making it more convenient for the user.

[0020] The winding mechanism 150 can be an automatic winding mechanism, meaning that the user can manually pull the connector 173 or the cable 171 to release the cable 171 from the winding mechanism 150. When the user releases the connector 173, the winding mechanism 150 can automatically wind up the cable 171 without the user having to manually rotate the winding mechanism 150. The specific structure of the winding mechanism 150 and the principle of automatic winding can be referred to in the existing technology and will not be described in detail here.

[0021] The support member 190 is disposed on the housing 110 and located on one radial side of the winding mechanism 150. A limiting space 200 is formed between the side of the support member 190 away from the winding mechanism 150 and the inner wall of the housing 110. One end of the wire 170 passes through the limiting space 200 and the wire hole 113 and extends outward from the housing 110, and is connected to the connector 173. Thus, the support member 190 can act as a lever to support the wire 171, thereby changing the movement path of the wire 171 when the winding mechanism 150 winds up the wire 171. This helps the center of gravity of the connector 173 to be closer to the positioning part 111. Under the action of the magnetic member 130, the connector 173 can be more smoothly and accurately stored in the positioning part 111, resulting in a better user experience.

[0022] As an example, the wire 171 may include a wound section and an extension section 1711 connected together. The wound section may be wound onto the winding mechanism 150, and the extension section 1711 may extend from the winding mechanism 150 outward from the housing 110. The extension section 1711 may include a first sub-segment located inside the housing 110 and a second sub-segment located outside the housing 110. The first sub-segment may be connected between the second sub-segment and the wound section. A connector 173 may be connected to the end of the second sub-segment away from the first sub-segment. The first sub-segment may pass through a limiting space and its length remains substantially constant. The second sub-segment may shorten as the winding mechanism 150 takes in the wire (i.e., takes in the wire 171) and lengthen as the winding mechanism 150 unwinds the wire (i.e., releases the wire 171). The wound section may lengthen as the winding mechanism 150 takes in the wire and shorten as the winding mechanism 150 unwinds the wire. The side of the second segment closest to the winding mechanism 150 can contact the support member 190. The support member 190 can act as a lever structure to change the extension direction of the second segment, for example, by adjusting the second segment from a straight line extension to an arc extension.

[0023] Because the wire 170 itself is flexible, when the extension direction of the second segment changes, the extension direction of the first segment will also be adjusted accordingly. Thus, during the winding process of the winding mechanism 150 winding the wire 171, the included angle between the wire 171 and the positioning part 111 decreases, thereby reducing the included angle between the connector 173 and the positioning part 111 (e.g., ...). Figure 3 The angle α in the middle makes the center of gravity of the connector 173 closer to the positioning part 111, which helps the magnetic component 130 to magnetically attract the connector 173 to the positioning part 111 more smoothly and accurately. This reduces the situation where the center of gravity of the connector 173 shifts due to the large distance between the center of gravity of the connector 173 and the positioning part 111, which in turn causes the torque of the connector 173 to become unbalanced and cause it to get stuck in the wire hole 113 and lift up.

[0024] The cross-sectional shape of line 171 can be circular, rectangular or other shapes.

[0025] In some embodiments, the housing 110 may include a housing body, a first cover, and a second cover.

[0026] The winding mechanism 150 can be located inside the shell body.

[0027] The shell body can be provided with an insertion hole, and a positioning part 111 is provided on one side of the shell body along the radial direction of the insertion hole. The first cover and the second cover are respectively connected to the opposite sides of the shell body along the axial direction of the insertion hole.

[0028] The first cover has a first positioning hole on the side facing the shell body, and the second cover has a second positioning hole on the side facing the shell body. Both the first and second positioning holes are opposite to the insertion hole. The support member 190 can be inserted into the insertion hole, and both ends of the support member 190 are respectively inserted into the first and second positioning holes, thereby facilitating the installation and replacement of the support member 190. During subsequent maintenance, it is not necessary to disassemble the entire telescopic cable device 100; only the first or second cover needs to be removed to expose part of the support member 190, making it easy to remove and replace the support member 190.

[0029] As an example, the shell body may include an end wall and an annular peripheral wall. The annular peripheral wall may surround the outer periphery of the end wall to form a receiving cavity, and the winding mechanism 150 may be disposed within the receiving cavity. The positioning part 111 may be disposed on the outer annular peripheral wall, the magnetic element 130 may be connected to the inner annular peripheral wall, and the wire through hole 113 may penetrate the annular peripheral wall. The receiving cavity may have an opening, and the opening and the end wall are disposed opposite each other at a distance. A first cover may be disposed on the opening, and a second cover may be disposed on the end wall. The side of the first cover facing the second cover may have a first protrusion, and the side of the second cover facing the first cover may have a second protrusion. The first protrusion may have a first positioning hole, and the second protrusion may have a second positioning hole, thereby extending the extension length of the first positioning hole and the second positioning hole, which helps to increase the insertion depth of the support member 190 in the first positioning hole and the second positioning hole, so as to prevent the support member 190 from falling off.

[0030] It should be noted that the two ends of the support member 190 can respectively engage with the wall of the first positioning hole and the second positioning hole, thereby allowing the support member 190 to rotate. When the winding mechanism 150 is winding or unwinding the wire 171, the wire 171 can drive the support member 190 to rotate, thereby reducing friction and wear on the wire 171. Alternatively, the two ends of the support member 190 can also be fixed in the first positioning hole and the second positioning hole, respectively.

[0031] The telescopic cable device 100 can have various structural forms. Specifically, in some embodiments, the telescopic cable device 100 may include two support members 190 and two cables 170 (e.g., Figure 2 As shown in the figure, the housing 110 may include two positioning parts 111 and two wire holes 113.

[0032] Each wire hole 113 corresponds to a positioning part 111. The first circuit board 153 can be connected to the winding mechanism 150, and the first circuit board 153 can rotate synchronously with the winding mechanism 150.

[0033] As an example, the winding mechanism 150 may include a winding reel 151 rotatably connected within the housing 110. A first circuit board 153 may be connected to the winding reel 151 and rotate synchronously with it.

[0034] The connector 173 and the positioning part 111 are in one-to-one correspondence. Each positioning part 111 is associated with a magnetic element 130, meaning that each connector 173 can be attracted to a positioning part 111 under the action of the corresponding magnetic element 130. Each positioning part 111 is associated with one or more magnetic elements 130, and "multiple" can refer to two or more.

[0035] The two support members 190 form a limiting space 200 between themselves and the inner wall of the housing 110. For example, the two limiting spaces 200 can be located on opposite sides of the winding mechanism 150 in the radial direction.

[0036] Both wires 170 have their wire bodies 171 wound onto the winding mechanism 150. One end of each wire body 171 is electrically connected to the first circuit board 153, while the other end extends out of the housing 110 through a limiting space and a wire through hole 113, respectively, and is connected to a connector 173. Thus, the first circuit board 153 can electrically connect to the connectors 173 of the two wires 170 to realize power and / or data transmission between the two connectors 173. The two support members 190 can act as levers for the two wire bodies 171 to adjust the movement path of each wire body 171, which helps the two connectors 173 to be more accurately housed in the corresponding positioning part 111 under the magnetic attraction of the corresponding magnetic member 130. That is, the wires 170, the limiting space 200, the wire through hole 113, and the positioning part 111 correspond one-to-one.

[0037] It should be noted that each wire body 171 contains multiple wire cores, and the first circuit board 153 may have multiple solder points to connect each wire core respectively. The multiple wire cores may include at least a positive power supply line (VBUS line), a negative power supply line (GND line), and a first signal line (CC1 line). In addition, the multiple wire cores may also include a second signal line (CC2 line), and / or, the multiple wire cores may also include a positive data transmission line (D+ line) and a negative data transmission line (D- line), as detailed in existing technology, which will not be elaborated further.

[0038] Please see Figure 2 and Figure 4In some embodiments, the retractable cord device 100 may further include a wireless charging coil 230 and a second circuit board 210 (e.g., Figure 4 (As shown).

[0039] The wireless charging coil 230 and the second circuit board 210 are both housed in the housing 110. The second circuit board 210 and the first circuit board 153 are slidably electrically connected. The wireless charging coil 230 is electrically connected to the second circuit board 210. Thus, the retractable cable device 100 can also have a wireless charging function, which expands the application scenarios of the retractable cable device 100 and better meets the user's needs.

[0040] As an example, the telescopic cable device 100 may also include a conductive spring, and the second circuit board 210 and the first circuit board 153 can be slidably electrically connected through the conductive spring. For details, please refer to the prior art.

[0041] In some embodiments, the telescopic cable device 100 may also include only one cable 170. Specifically, the cable 170 may include two connectors 173. The two ends of the cable 171 are respectively passed through a limiting space 200 and a cable hole 113 extending the housing 110, and each is connected to a connector 173. The two connectors 173 can transmit power and / or data through the cable 171. The two support members 190 can be used as levers at both ends of the cable 171 to adjust the movement path of the two ends of the cable 171, which helps the two connectors 173 to be more accurately housed in the corresponding positioning part 111 under the magnetic attraction of the corresponding magnetic member 130.

[0042] Each connector 173 can be magnetically attached to the corresponding positioning part 111, as can be seen in the above embodiment, and will not be repeated here.

[0043] In some embodiments, when the retractable cable device 100 includes only one cable 170, the retractable cable device 100 can also realize wireless charging functionality. Specifically, the cable body 171 may include an electrical connection portion, which may be located between the two ends of the cable body 171. The electrical connection portion may be electrically connected to the first circuit board 153, and the second circuit board 210 and the first circuit board 153 are slidably electrically connected. The wireless charging coil 230 is electrically connected to the second circuit board 210, thereby enabling the retractable cable device 100 to realize wireless charging functionality.

[0044] The core structure inside the cable 171 can refer to the core structure in the above embodiment, wherein the positive power line (VBUS line), the negative power line (GND line), and the first signal line (CC1 line) can all be electrically connected to the corresponding solder points on the first circuit board 153, so that each connector 173 can supply power to the wireless charging coil 230.

[0045] In some embodiments, the telescopic cord device 100 may also include a magnetic structure, which may be disposed inside the housing 110 for attaching the device to the outside of the housing 110, thereby helping the wireless charging coil 230 to supply power to the device more stably.

[0046] Magnetic structures can use magnets.

[0047] In some embodiments, the retractable cable device 100 can also be used as a charging plug. Specifically, one end of the cable 171 is connected to a connector, and the other end can be electrically connected to the first circuit board 153. The power plug can be electrically connected to the second circuit board 210. Since the first circuit board 153 and the second circuit board 210 are slidably electrically connected, the connector 173 and the power plug can be electrically connected through the cable 171, the first circuit board 153, and the second circuit board 210. Thus, the retractable cable device 100 can be directly used as a charging plug without the need for an external charging head. The connection method of the first circuit board 153 and the second circuit board 210 can refer to the above embodiments and will not be repeated here.

[0048] The power plug can be pivotally attached to the housing 110, making it easy to store the power plug.

[0049] As an example, the outer wall of the housing 110 may be provided with a storage slot for storing the power plug.

[0050] For ease of description, the following explanation will use a connector 173 as an example.

[0051] Please see Figures 1 to 3 In some embodiments, the minimum distance between the inner wall of the radial housing 110 of the winding mechanism 150 and the support 190 (e.g.) Figure 2 The dimension L in the middle is ≥3mm and ≤6mm. Specifically, the distance between the support member 190 and the annular peripheral wall closest to the support member 190 is ≥3mm and ≤6mm. This helps the support member 190 to better adjust the movement path of the line body 171, so as to reduce the included angle between the connector 173 and the positioning part 111, and help the connector 173 to be more accurately and smoothly housed in the positioning part 111.

[0052] As an example, the minimum distance between the inner wall of the radial housing 110 of the winding mechanism 150 and the support 190 can be 3 mm, 3.5 mm, 5 mm, 5.3 mm, 6 mm or other values.

[0053] In some embodiments, abutment portion 1131 is formed in a portion of the wall of the wire hole 113.

[0054] The abutment portion 1131 is used to contact the side of the cable 171 away from the winding mechanism 150, while the side of the cable 171 close to the winding mechanism 150 abuts against the support member 190. Thus, during the winding process of the winding mechanism 150, the support member 190 and the abutment portion 1131 can simultaneously abut against the cable 171 to provide two support points for the cable 171. This helps to better adjust the movement path of the cable 171 and better reduce the included angle between the connector 173 and the positioning portion 111.

[0055] It should be noted that in some other embodiments, the hole wall of the wire hole 113 does not need to form an abutment portion 1131. Specifically, the number of support members 190 supporting the wire body 171 can be two (that is, each extension segment 1711 can be supported by two support members 190). The wire body 171 can be passed between the two support members 190. The two support members 190 can also provide two support points for the wire body 171. The extension direction of the wire body 171 outside the housing 110 can be adjusted by adjusting the relative position of the two support members 190, thereby adjusting the included angle between the connector 173 and the positioning portion 111.

[0056] In some embodiments, the wire hole 113 may have a first opening and a second opening spaced apart from each other.

[0057] The first opening can communicate with the internal space of the housing 110, and the second opening can communicate with the external space outside the housing 110, so that the wire 171 can extend to the outside of the housing 110 through the wire hole 113.

[0058] The rounded chamfered edges of the first and / or second orifices help reduce wear on the wire 171 at the orifice edges and extend the service life of the wire 170.

[0059] It should be noted that the abutting part 1131 can be located at a local position on the edge of the first hole, or at a local position on the inner wall of the wire hole 113. For example, the inner peripheral wall of the wire hole 113 can be arched in an arc shape towards the inside of the wire hole 113, and the arc-shaped arch or a local position of the arc-shaped arch can be used as the abutting part 1131.

[0060] In some embodiments, the positioning part 111 may have a magnetic surface 1113, and the connector 173 may be attached to the magnetic surface 1113. Specifically, the connector 173 may be attracted to the magnetic surface 1113 under the action of the magnetic element 130.

[0061] The magnetic surface 1113 can be a flat surface or a surface that matches the shape of the outer surface of the connector 173.

[0062] Understandably, the magnetic component 130 can be installed inside the housing 110 on the inner wall opposite to the magnetic surface 1113 using the magnetic connector 173. This makes the installation of the magnetic component 130 more convenient and eliminates the need to provide a groove for installing the magnetic component 130 in the positioning part 111, simplifying the structure of the housing 110. In addition, the magnetic component 130 can be hidden inside the housing 110, which helps to improve the aesthetic appearance of the telescopic cable device 100.

[0063] The support member 190 is used to reduce the included angle between the connector 173 and the magnetic surface 1113 during the winding process of the winding mechanism 150 winding the wire body 171. As a result, after the winding mechanism 150 winds up the wire body 171, the center of gravity of the connector 173 can be closer to the magnetic surface 1113, which helps the connector 173 to be more smoothly and accurately stored in the magnetic surface 1113 under the action of the magnetic member 130.

[0064] In some embodiments, the positioning part 111 may be provided with a positioning groove 1111.

[0065] The wire hole 113 and the positioning groove 1111 can be connected, thereby shortening the distance between the wire hole 113 and the positioning groove 1111. After the winding mechanism 150 winds up the wire 171, the length of the wire 171 between the connector 173 and the wire hole 113 is shorter, reducing the possibility of the connector 173 shaking and causing the center of gravity to shift, which helps the connector 173 to be more accurately magnetically attracted into the positioning groove 1111.

[0066] As an example, the second opening can be provided on the inner wall of the positioning groove 1111 to connect the positioning groove 1111.

[0067] The positioning groove 1111 may have a groove opening and a groove bottom wall that are radially spaced opposite each other along the winding mechanism 150. The groove bottom wall may be located between the groove opening and the winding mechanism 150, so that the connector 173 can enter or leave the positioning groove 1111 through the groove opening.

[0068] The bottom wall of the tank may have a magnetic surface 1113, and the magnetic component 130 may be connected to the inner wall of the housing 110 opposite to the bottom wall of the tank.

[0069] In some embodiments, the included angle between the central axis of the wire hole 113 and the magnetic surface 1113 (e.g.) Figure 3 The included angle β) is less than 90 degrees, which can reduce the included angle between the wire 171 outside the housing 110 and the magnetic surface 1113 when the wire 171 enters the housing 110 through the wire hole 113. This helps to further reduce the included angle between the connector 173 and the magnetic surface 1113, and the connector 173 can be more smoothly and accurately housed in the magnetic surface 1113 under the action of the magnetic component 130.

[0070] As an example, the angle between the central axis of the wire hole 113 and the magnetic surface 1113 can be 89 degrees, 85 degrees, 60 degrees, 50 degrees, 45 degrees, 10 degrees, 1 degree or other angle values.

[0071] In some other embodiments, the angle between the central axis of the wire hole 113 and the magnetic surface 1113 can also be 0 degrees, that is, the central axis of the wire hole 113 and the magnetic surface 1113 are parallel.

[0072] In some embodiments, the support member 190 is rotatably connected to the housing 110. Thus, during the winding or unwinding process of the winding mechanism 150, the wire 171 can drive the support member 190 to rotate, thereby reducing the friction between the wire 171 and the support member 190, which helps to reduce the wear of the wire 171 and extend the service life of the wire 171.

[0073] As an example, the support member 190 can be a shaft structure, such as a steel needle or other shaft structure. The axis of rotation of the support member 190 can be parallel or substantially parallel to the axis of rotation of the winding mechanism 150.

[0074] In some embodiments, the support 190 may include a connecting rod and a bearing.

[0075] The connecting rod can be connected to the housing 110, the inner ring of the bearing can be fitted onto the connecting rod, and the outer ring of the bearing is used to contact the side of the wire 171 near the winding mechanism 150. In this way, during the winding or unwinding process of the winding mechanism 150, the wire 171 can drive the outer ring of the bearing to rotate, which can also reduce the friction between the wire 171 and the outer ring of the bearing.

[0076] The rotation axis of the outer ring of the bearing can be parallel or approximately parallel to the rotation axis of the winding mechanism 150.

[0077] In some embodiments, the support 190 may include a connecting rod and a rotating element.

[0078] The connecting rod can be connected to the housing 110, and the rotating part is rotatably sleeved on the connecting rod. The rotating part is used to contact the side of the wire 171 that is close to the winding mechanism 150. In this way, during the winding or unwinding process of the winding mechanism 150, the wire 171 can drive the rotating part to rotate, which can also reduce the friction between the wire 171 and the rotating part.

[0079] The shape of the rotating component can be customized as needed; for example, it can be spherical, annular, cylindrical, or other shapes. The axis of rotation of the rotating component can be parallel or approximately parallel to the axis of rotation of the winding mechanism 150.

[0080] In the telescopic cord device 100 provided in this application embodiment, by winding the cord 171 of the cord 170 onto the winding mechanism 150, the winding mechanism 150 can accommodate a longer cord 171, and the user does not need to organize the cord 171, making it more convenient for the user. By placing the support member 190 on the housing 110 and located on one radial side of the winding mechanism 150, a limiting space 200 is formed between the side of the support member 190 away from the winding mechanism 150 and the inner wall of the housing 110. One end of the wire 170 passes through the limiting space 200 and the wire hole 113, extends outward from the housing 110, and is connected to the connector 173. Thus, the support member 190 can act as a lever to support the wire 171, thereby changing the movement path of the wire 171 when the winding mechanism 150 winds up the wire 171. This helps the center of gravity of the connector 173 to be closer to the positioning part 111. Under the action of the magnetic member 130, the connector 173 can be more smoothly and accurately stored in the positioning part 111, resulting in a better user experience.

[0081] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
