[0002] In related technologies, charging devices integrating retractable data cables commonly employ magnetic designs to secure the connector at the end of the cable after it retracts. This involves embedding magnets in both the data cable connector and the charging device's storage cavity. However, due to the need for a compact and thin design for the charging device, the size and thickness of these magnets cannot be increased, resulting in insufficient magnetic force. Consequently, this leads to lower accuracy and success rate in attracting the data cable connector during storage. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Related technologies generally employ a dual-magnet magnetic attraction scheme, using the attraction between opposite poles of two magnetic bodies to attract and fix the plug inside the storage cavity. However, due to the overall design requirement of a compact and thin charging device, the size and thickness of these two magnets cannot be increased, resulting in insufficient magnetic force. This leads to insufficient stability and reliability of the connector, making it easy for the connector to detach from the storage cavity. Secondly, dual-magnet magnetic attraction requires stringent alignment precision, and its success rate is relatively low. In practical applications, users often quickly and casually return the plug to its proper position, making it difficult to guarantee that the plug will always be in an ideal aligned state when entering the storage cavity. Once misaligned, the magnetic poles will be misaligned, causing the magnetic force to weaken drastically and preventing the connector from being effectively secured.

[0022] Furthermore, from a manufacturing perspective, assembling two magnets requires precise identification of their polarities to ensure they are paired and installed with opposing polarities. This not only increases the difficulty and complexity of assembly but also raises the error rate.

[0023] To address the aforementioned problems, some embodiments of this utility model propose a data cable storage component 1000, suitable for charging devices such as wired power banks, charging plugs 10, and charging converters. This component improves the stability and reliability of magnetic fixation and also increases the success rate of magnetic attraction. See details below. Figures 1 to 6 The data cable storage component 1000 is described in the figure.

[0024] For ease of description, the following description will use charging plug 10 as an example. (Refer to...) Figure 1 and Figure 2 As shown in the embodiment of this utility model, the charging plug 10 includes a housing 2000 and a data cable storage assembly 1000, wherein the housing 2000 has an inner cavity, and the data cable storage assembly 1000 is installed in the inner cavity.

[0025] Reference Figure 2 As shown in this embodiment of the invention, the data cable storage component 1000 includes: a cable 100, a storage mechanism 200, and a base 300. The cable 100 is a flexible conductor with power transmission function, specifically a copper core wire with an outer insulation layer, used to connect electronic devices to a power source. In this embodiment, one end of the cable 100 is provided with a connector 110 for connecting to an electronic device. The connector 110 can be a Lightning interface, a Type-C interface, a USB interface, etc., and this embodiment does not limit the type.

[0026] Combination Figure 3 It is understood that in this embodiment of the invention, the storage mechanism 200 is connected to the cable 100 and is configured to retract or release the cable 100. Specifically, the storage mechanism 200 is a mechanical structure with the function of retracting and releasing the cable 100, which can be implemented by using a rotating reel in conjunction with a spring reset mechanism to control the storage and unfolding of the cable 100. The base 300 serves as a fixed structure for supporting the connector 110, and can be implemented by using an injection-molded plastic shell 2000. The base 300 is configured to store the connector 110 when the storage mechanism 200 retracts the cable 100.

[0027] In this embodiment of the invention, the connector 110 is fixed to the base 300 by a magnetic attraction assembly 400. Specifically, the magnetic attraction assembly 400 includes a magnetic conductor 410 and a magnet array 420. One of the magnetic conductor 410 and the magnet array 420 is disposed on the connector 110, and the other is disposed on the base 300. The magnetic conductor 410 and the magnet array 420 are magnetically connected. In one example, the magnetic conductor 410 is disposed on the connector 110, and the magnet array 420 is disposed on the base 300; in another example, the magnet array 420 is disposed on the connector 110, and the magnetic conductor 410 is disposed on the base 300.

[0028] Understandably, the magnetic conductor 410 has high magnetic permeability and can be made of magnetically conductive materials such as pure iron or low-carbon steel. The magnet array 420 refers to a combination of magnets consisting of multiple permanent magnets 421 arranged in a specific polarity, which can generate a high-intensity magnetic field on one side.

[0029] Specifically, when the storage mechanism 200 winds up the cable 100, the cable 100 moves the connector 110 towards the base 300. The magnet array 420 inside the base 300 generates a high-intensity directional magnetic field, which forms a concentrated magnetic circuit through the magnetic conductor 410. The magnetic attraction between the magnetic conductor 410 and the magnet array 420 overcomes the rebound force of the cable 100, stably attracting the connector 110 to a designated position on the base 300. The magnet array 420 forms a uniform, strong magnetic field, and the magnetic conductor 410 can form an effective magnetic circuit at any position within this magnetic field range, thereby reducing the requirements for connector repositioning accuracy.

[0030] Understandably, traditional solutions using two permanent magnets 421 to attract each other require precise matching of magnetic pole directions and dispersed magnetic field lines. This embodiment of the invention, through the combination of a magnetic conductor 410 and a magnet array, requires only a single magnet. The magnetic conductor 410 guides the magnetic field distribution, reducing the number of magnets used while maintaining magnetic attraction. The data cable storage component 1000 of this utility model uses a storage mechanism 200 to wind or unwind the cable 100. When the storage mechanism 200 winds the cable 100, the connector 110 is stored in the base 300. The connector 110 is magnetically fixed to the base 300 by a magnetic attraction component 400. The magnetic attraction component 400 includes a magnetic conductor 410 and a magnet array 420. One of the magnetic conductor 410 and the magnet array 420 is located in the connector 110, and the other is located in the base 300. By utilizing the unilateral magnetic field enhancement effect of the magnet array 420, a certain amount of magnetic field enhancement is achieved within a limited volume. The magnetic attraction force is greater than that of traditional dual permanent magnet solutions, thus improving the stability and reliability of magnetic fixation. Furthermore, by employing a non-polar magnetic conductor 410 in conjunction with a magnet array 420 possessing a strong, wide-range magnetic field, the success rate of attraction between the base 300 and the connector 110 is increased, thereby improving the ease of winding up the cable 100. In addition, the single-sided magnet structure reduces assembly steps, simplifies the assembly process of the data cable storage assembly 1000, avoids failures caused by reversed magnetic pole installation, reduces the assembly error rate, and further improves the reliability of the data cable storage assembly 1000. (Refer to...) Figure 2As shown, in this embodiment of the present invention, a magnetic conductor 410 is disposed on a connector 110, and a magnet array 420 is disposed on a base 300. Specifically, a first mounting groove 111 is provided inside the connector 110, and the magnetic conductor 410 is installed in the first mounting groove 111. The first mounting groove 111 is a recessed structure provided inside the connector 110, which is used to accommodate the magnetic conductor 410 and limit its displacement. The base 300 is provided with a contact surface 310 that fits against the connector 110. It can be understood that the contact surface 310 refers to a plane or curved surface on the base 300 that matches the shape of the surface of the connector 110. Specifically, it can be achieved by mold forming, which is used to ensure that a uniform contact area is formed when the connector 110 and the base 300 are fitted together.

[0031] Continue to refer to Figure 2 As shown in this embodiment of the invention, a second mounting groove 320 is provided on the side of the base 300 facing away from the contact surface 310, and the magnet array 420 is installed in the second mounting groove 320. In this embodiment, the second mounting groove 320 is a recessed structure provided on the base 300 facing away from the connector 110, and can be formed by milling or stamping processes. It is used to fix the magnet array 420 and control its installation position.

[0032] Specifically, when the cable 100 is wound up by the storage mechanism 200, the connector 110 is pulled to the base 300 area. The corresponding arrangement of the first mounting groove 111 and the second mounting groove 320 enables the magnetic conductor 410 and the magnet array 420 to be automatically aligned in space, and the matching of the contact surface 310 and the outer surface of the connector 110 further ensures that the magnetic attraction surfaces between them remain parallel.

[0033] Reference Figure 3 and Figure 4 As shown in this embodiment of the invention, the base 300 has a first end 330 and a second end 340 disposed opposite to each other. In this embodiment, the first end 330 and the second end 340 are two ends of the base 300 along its length. The second end 340 is provided with a wire hole 350, which is a through hole structure that passes through the second end 340 of the base 300 and can constrain the movement trajectory of the cable 100 during the winding process.

[0034] by Figure 4 Taking the left-right direction as an example, when the storage mechanism 200 winds up the cable 100, the cable 100 can pass through the cable hole 350 and drive the connector 110 to move into the base 300 from the first end 330 toward the second end 340. Specifically, during the winding process, the cable 100 gradually passes through the cable hole 350 to the left, and the resulting tension is transmitted to the connector 110, causing the connector 110 to move along the length of the base 300, moving into the base 300 from right to left, and finally fitting against the contact surface 310 of the base 300.

[0035] Reference Figure 4 and Figure 5 As shown in this embodiment of the invention, the magnet array 420 includes at least three permanent magnets 421. In this embodiment, the directional arrangement of the three magnets forms a composite magnetic field, which not only increases the effective adsorption area but also reduces the requirements for the positioning accuracy of the connector 110. Under the same volume constraints, the magnetic field strength generated by the combination of multiple magnets is significantly higher than that of a single magnet structure, and reliable fixation can be achieved without strict alignment.

[0036] Reference Figure 4 As shown, in this embodiment of the invention, along the arrangement direction of at least three permanent magnets 421, in any two adjacent permanent magnets 421, the magnetization direction of the latter permanent magnet 421 is deflected by a preset angle relative to the magnetization direction of the former permanent magnet 421, and the magnetization directions of all permanent magnets 421 are cumulatively rotated 360°. Figure 4 Taking the left-right direction as an example, the arrangement direction of at least three permanent magnets 421 can be from left to right or from right to left.

[0037] In one example, along a left-to-right direction, the magnetization direction of the second permanent magnet 421 is rotated 45° clockwise relative to the magnetization direction of the first permanent magnet 421, the magnetization direction of the third permanent magnet 421 is rotated 45° clockwise relative to the magnetization direction of the second permanent magnet 421, and so on, until the magnetization directions of all permanent magnets 421 have completed a full 360° rotation cycle. (Continue referring to...) Figure 4 As shown, in this embodiment of the invention, at least three permanent magnets 421 are arranged sequentially from the first end 330 toward the second end 340. In other words, the arrangement direction of the at least three permanent magnets 421 is consistent with the moving direction of the connector 110 when the cable 100 is wound up. Since the three permanent magnets 421 are linearly arranged along the moving direction, a continuous magnetic field gradient can be formed as the connector 110 approaches. This arrangement allows the connector 110 to experience similar magnetic attraction at different positions along the moving path. Even with slight positional deviations, effective attraction can still be maintained through the superposition of the magnetic fields of adjacent magnets.

[0038] In one example, the magnetization directions of two adjacent permanent magnets 421 are not perpendicular. For example, the magnetization direction of the first permanent magnet 421 from left to right forms an angle of 45° with the magnetization direction of the second permanent magnet 421, and the magnetization direction of the third permanent magnet 421 forms an angle of 45° with the magnetization direction of the second permanent magnet 421.

[0039] Reference Figure 5As shown, in another example, the magnetization directions of two adjacent permanent magnets 421 are perpendicular to each other. In one example, the magnet array 420 consists of four linearly arranged, square-shaped neodymium iron boron permanent magnets 421. From left to right, the first permanent magnet 421 is magnetized vertically upwards, the second permanent magnet 421 is magnetized vertically to the left, the third permanent magnet 421 is magnetized vertically downwards, the fourth permanent magnet 421 is magnetized vertically to the right, and the fifth permanent magnet 421 is magnetized vertically upwards.

[0040] Reference Figure 2 and Figure 4 As shown, in this embodiment of the present invention, the connector 110 includes a main body 112 and a housing 113. The main body 112 refers to the component constituting the core structure of the connector 110. One end of the main body 112 is connected to the cable 100, and the other end is a port for connecting to electronic equipment. The first mounting groove 111 is constructed as a recess formed in the outer peripheral wall of the main body 112. The housing 113 is sleeved on the outside of the main body 112 and closes the groove. The sealing effect of the housing 113 on the first mounting groove 111 can prevent the magnetic conductor 410 from falling off during insertion and removal.

[0041] It is understood that, in this embodiment of the invention, the sleeve structure between the outer shell 113 and the main body 112 simplifies the production process, and the outer shell 113 can be quickly assembled by automated equipment, improving assembly efficiency. The recessed design of the first mounting groove 111 physically isolates the mounting position of the magnetic conductor 410 from the inner wall of the outer shell 113. When the plug is subjected to external force, the deformation of the outer shell 113 will not be directly transmitted to the magnetic conductor 410, ensuring the reliability of the magnetic fixation.

[0042] Reference Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the inner wall of the outer shell 113 and the bottom wall of the first mounting groove 111 clamp the magnetic conductor 410; and / or, the magnetic conductor 410 is bonded to the bottom wall of the first mounting groove 111. In one example, the magnetic conductor 410 is fixed only by the clamping of the inner wall of the outer shell 113 and the bottom wall of the first mounting groove 111; in another example, the magnetic conductor 410 is fixed only by bonding; in yet another example, the magnetic conductor 410 is bonded to the bottom wall of the first mounting groove 111, while the inner wall of the outer shell 113 and the bottom wall of the first mounting groove 111 clamp the magnetic conductor 410.

[0043] It should be noted that the clamping of the magnetic conductor 410 between the inner wall of the outer shell 113 and the bottom wall of the first mounting groove 111 refers to the application of mechanical clamping force to the magnetic conductor 410 through the assembly structure between the outer shell 113 and the main body 112. Specifically, this can be achieved by having the inner wall of the outer shell 113 fitted onto the outside of the main body 112 form a clearance fit or an interference fit with the bottom wall of the first mounting groove 111. For example, the inner wall of the outer shell 113 may have protrusions or snap-fit ​​structures to press against the magnetic conductor 410. The magnetic conductor 410 being bonded to the bottom wall of the first mounting groove 111 means that the magnetic conductor 410 is fixed to the bottom surface of the mounting groove using an adhesive.

[0044] Specifically, after the magnetic conductor 410 is placed in the first mounting groove 111, the outer shell 113 closes the first mounting groove 111 by fitting it onto the outside of the main body 112. At this time, the inner wall of the outer shell 113 and the bottom wall of the first mounting groove 111 form a clamping space. Through mechanical cooperation, a clamping force perpendicular to the surface of the magnetic conductor 410 is applied, restricting the displacement of the magnetic conductor 410 in the groove. At the same time, the magnetic conductor 410 is bonded to the bottom wall, further eliminating the slight slippage that may occur under vibration or impact. The dual effect of mechanical clamping and adhesive fixation significantly improves the positional stability of the magnetic conductor 410 in the groove, avoiding uneven distribution or attenuation of magnetic attraction force due to the displacement of the magnetic conductor 410.

[0045] Reference Figure 1 and Figure 6 As shown, in this embodiment of the present invention, the storage assembly further includes a panel 500, which is connected to the base 300. Specifically, the panel 500 is a structural member covering the surface of the base 300 facing the connector 110, and it is connected to the housing 2000 to form the external structure of the charging plug 10. In this embodiment, the panel 500 is provided with a receiving groove 510, which is a cavity structure formed by an inward recess from the surface of the panel 500, used to limit the range of movement of the connector 110 so that it does not protrude from the outer contour of the charging plug 10. The contact surface 310 is configured as at least a part of the bottom wall of the receiving groove 510; in other words, the contact surface 310 acts as at least a part of the bottom wall of the receiving groove 510, thereby supporting the connector 110. When the storage mechanism 200 winds up the cable 100, the entire connector 110 is located within the receiving groove 510. Specifically, the panel 500 is fixedly connected to the base 300 by clips or screws, and the depth of the receiving groove 510 is set to be slightly greater than the thickness of the connector 110. When the cable 100 is fully retracted, the retraction force generated by the retracting mechanism 200 causes the connector 110 to move along the extension direction of the receiving groove 510 until the connector 110 is fully embedded in the receiving groove 510.

[0046] Reference Figure 3 and Figure 6As shown in this embodiment of the invention, at least a portion of the inner peripheral wall of the receiving groove 510 is constructed as an arc surface 511, which is configured to guide the connector 110 into the receiving groove 510. It should be noted that the arc surface 511 refers to a continuous curved surface formed on the inner wall of the receiving groove 510, which can be implemented using a circular arc or parabolic curved surface, and its radius of curvature can be set to adapt to the movement trajectory of the connector 110.

[0047] Specifically, when the storage mechanism 200 winds up the cable 100, the cable 100 drives the connector 110 to move towards the receiving groove 510. After the arc surface 511 at the entrance of the receiving groove 510 contacts the outer contour of the connector 110, the curved surface contact pushes the connector 110 to slide into the groove along a predetermined trajectory. As the connector 110 continues to move, the tangent direction at different positions of the arc surface 511 continuously adjusts the movement direction of the connector 110, so that it is finally accurately aligned with the magnetic conductor 410 on the bottom wall of the receiving groove 510. This realizes the automatic trajectory correction function during the repositioning process of the connector 110, effectively eliminating the alignment deviation of the magnetic suction component 400 caused by operational deviation, and significantly improving the adsorption success rate when storing the plug.

[0048] Reference Figure 3 and Figure 4 As shown in this embodiment of the invention, the thickness of the magnetic conductor 410 is w along the direction from the magnetic conductor 410 toward the magnet array 420, satisfying the condition: 1mm ≤ w ≤ 3mm. For example, w can take values ​​of 1mm, 1.24mm, 1.8mm, 2mm, 2.4mm, 3mm, etc. Specifically, the thickness of the magnetic conductor 410 is limited to between 1mm and 3mm. This range optimizes the magnetic attraction effect by balancing magnetic flux conduction efficiency and structural compactness.

[0049] It is understandable that when the thickness of the magnetic conductor 410 is too thin, magnetic flux saturation will lead to a decrease in magnetic field strength; while excessive thickness will increase the volume of the overall structure. This embodiment of the invention, by reasonably limiting the range of values ​​for w, enables the magnetic conductor 410 to effectively transmit the magnetic field generated by the magnet array 420, while avoiding the impact of excessive size on the slim design of the data cable storage component 1000.

[0050] This utility model also provides a charging plug 10, which includes the data cable storage component 1000 described in the above embodiment. Specifically, the charging plug 10 in this embodiment can be a charging device for electronic devices such as mobile phones, power banks, and laptops, and this embodiment does not limit it to this.

[0051] The charging plug 10 of this utility model embodiment adopts the data cable storage component 1000 of the above embodiment. By optimizing the structural design of the data cable storage component 1000, the success rate of adsorption between the base 300 and the connector 110 is improved, thereby improving the smoothness when recycling the data cable. It also improves the stability and reliability of magnetic fixation, reduces the vibration of the connector 110 in the non-use state, thereby reducing the risk of the connector 110 falling off, and thus improving the durability of the charging plug 10.

[0052] Since the charging plug 10 adopts all the technical solutions of the data cable storage component 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0053] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
