Description

Technical Field

[0001] This invention relates to the field of charging device technology, and in particular to a multimode magnetic charging device that integrates a telescopic data cable and a flip stand. Background Technology

[0002] With the widespread adoption of electronic device charging technology, magnetic chargers have gained market favor due to their automatic alignment, secure attachment, and ease of use. Meanwhile, products combining chargers and phone stands are also common to meet desktop office or entertainment needs. However, existing products typically have limited functionality, either functioning only as a charging dock or a stand, and often only supporting a single device.

[0003] To address the issue of limited functionality in charging devices, some modular products have emerged on the market. However, these products are often bulky and inconvenient to carry. Charging products with retractable data cables are mostly standalone, failing to organically integrate the magnetic structure with the stand function. Even in products with stands, the angle is mainly fixed by bolts tightening the pivot between the product and the stand to generate sufficient friction to support the weight of the electronic device and the product itself. After prolonged use, as the bolts and pivot wear down, the stand can no longer provide stable support. Summary of the Invention

[0004] The main objective of this invention is to provide a multi-mode magnetic charging device that integrates a retractable data cable and a flip stand, aiming to integrate multiple functions simultaneously and achieve a highly integrated overall structure.

[0005] To achieve the above objectives, the present invention proposes a multi-mode magnetic charging device integrating a retractable data cable and a flip stand, comprising: The casing is equipped with a magnetic attraction structure; The first transmission line is provided with a first interface end, which is used to connect to electrical equipment or power supply equipment. A rotating assembly, disposed within the housing, rotates relative to the housing to wind up or unwind the first transmission line; A bracket is rotatably connected to one side of a housing via a pivot. The housing has a storage slot for accommodating the bracket. A retaining mechanism is provided between the bracket and the housing, which includes a limiting component and a releasing component. The limiting component is coaxially arranged with the pivot. The limiting component has a limiting seat inside the bracket and multiple limiting blocks arranged in a circumferential array facing the housing. The limiting blocks are tilted at an angle relative to the unfolding direction of the bracket. A reset structure is provided between the limiting seat and the bracket on the side facing away from the housing. The limiting component has a mating seat on the housing opposite to the limiting seat and a limiting groove circumferentially formed to mate with the limiting blocks. The releasing component is connected to the side of the limiting seat facing the mating seat and extends out of the bracket to form an operating element. Under the action of the operating element, the releasing component pushes the limiting seat, causing the limiting blocks to separate from the limiting grooves. A charging module is disposed inside the housing, the charging module being capable of storing electrical energy and / or charging electrical devices; the charging module is electrically connected to a first transmission line. When the casing is magnetically attached to the phone, the bracket can be extended to a set angle to support the phone.

[0006] In one embodiment of this application, the release component includes: A release element is disposed within the bracket and positioned between the limiting seat and the mating seat. The release element includes a pressure ring and a drive bar. The pressure ring is connected to the outer periphery of the limiting seat, and the drive bar is connected to the pressure ring and a reset guide is provided between the release element and the bracket. The operating component is connected to the drive bar and extends out of the bracket.

[0007] In one embodiment of this application, the rotating assembly is provided with a stop plate relative to the housing, and the housing is provided with a stop member relative to the stop plate; The stop disc is provided with an adjustment groove relative to the stop member. The first end of the stop member is rotatably connected to the housing, and the second end of the stop member is slidably connected to the adjustment groove. The second end is configured to have a tendency to rotate toward the inner wall of the adjustment groove during movement. The adjusting groove includes an outer sliding groove and an inner sliding groove arranged sequentially along the radial direction of the stop plate. The inner sliding groove and the outer sliding groove are connected by a reversing block. One end of the reversing block is connected to the inner sliding groove, and the other end is connected to the outer sliding groove. The reversing block has a stop groove on the side facing the receiving direction of the first transmission line. The stop groove opens towards the outer sliding groove and has a guide channel connecting to the inner sliding groove. When the rotating assembly slowly retracts or extends the first transmission line, the second end of the stopper slides freely in the inner groove. When the first transmission line is quickly pulled out, the second end enters the outer groove through the reversing block under inertia. When the first transmission line is released, the second end slides along the outer groove and is guided into the stop groove to lock. When it is necessary to release the lock, the first transmission line is pulled again, and the second end is guided back into the inner groove along the guide channel, restoring the free rotation state.

[0008] In one embodiment of this application, the inner groove includes an adjustment section and a sliding section, wherein the diameter of the adjustment section is larger than that of the sliding section and is connected to the outer wall of the reversing block; A guide section connected to the sliding section is formed by bending between the adjustment section and the reversing block. When the first transmission line is slowly extended or retracted, the second end slides freely between the sliding section and the adjusting section through the guide section; when the first transmission line is quickly pulled out, the second end enters the outer slide groove through the commutator block under the action of inertia.

[0009] In one embodiment of this application, a second transmission line electrically connected to the charging module and having a second interface end is further included. The housing is provided with a wire outlet hole, a limiting hole, and a wire release hole relative to the second transmission line. When the second interface end is fixed to the housing, a hanging rope structure is formed between the wire outlet hole and the limiting hole of the second transmission line.

[0010] In one embodiment of this application, the outer side of the housing is further provided with at least two receiving slots, and the first interface end and the second interface end are accommodated in the corresponding receiving slots. The receiving slots are provided with arc-shaped guide surfaces for guiding the movement of the first interface end or the second interface end.

[0011] In one embodiment of this application, a wireless charging module electrically connected to the charging module is also included; It includes at least a first wireless charging component and a second wireless charging component. The first wireless charging component is located on the side of the housing away from the bracket, and the housing can be magnetically fixed to the mobile phone via the first wireless charging component. The second wireless charging component is located on the bracket, and the second wireless charging component can magnetically fix the watch to the bracket.

[0012] In one embodiment of this application, the housing further includes a first outer shell, a second outer shell, and a third outer shell; The first outer shell and the second outer shell are detachably connected to each other and form an installation cavity. The storage groove is recessed on the side of the first outer shell away from the second outer shell. The third outer shell is detachably connected to the side of the second outer shell opposite to the first outer shell, and forms a storage cavity for storing the first wireless charging component.

[0013] In one embodiment of this application, the storage slot is located on the side of the first outer shell away from the second outer shell, and the first outer shell is provided with a clearance slot communicating with the storage slot. The clearance slot is located at the rotating end of the storage slot away from the bracket. The bracket has an operating section relative to the storage slot.

[0014] As can be seen from the above, the multi-mode magnetic charging device integrating a retractable data cable and a flip stand provided in this application integrates an automatically retractable transmission cable, a flip-positionable stand, a dual magnetic wireless charging component, and a charging module into one unit. After the phone is magnetically fixed in the shell, the stand can be unfolded to support the phone. At the same time, the stand can accommodate a watch for magnetic charging, and the retractable data cable can be pulled out for emergency wired charging. It does not require multiple independent devices to work together, solving the problems of large space occupation, inconvenience of carrying, and cumbersome operation of existing multi-functional charging solutions. It has the advantages of being able to provide magnetic charging for both mobile phones and watches at the same time, integrating the functions of an automatically retractable data cable and a flip stand, having a compact structure that is easy to carry, convenient to operate, and being able to meet the needs of charging multiple devices at the same time and supporting mobile phone use.

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] The following is in conjunction with the appendix Figures 1 to 15 The present invention will be further described below.

[0021] To achieve the above objectives, the present invention proposes a multimode magnetic charging device integrating a retractable data cable and a flip stand 6, comprising a housing 1, a first transmission line 2, a rotating component 3, a stand 6, a wireless charging module 9, and a charging module 10; The housing 1 is equipped with a magnetic attraction structure; The first transmission line 2 is provided with a first interface terminal 21, which is used to connect electrical equipment or power supply equipment. The rotating component 3 is disposed inside the housing and rotates relative to the housing 1 to wind up or unwind the first transmission line 2; The bracket 6 is rotatably connected to one side of the housing 1 via a pivot. The housing 1 is provided with a storage groove 13 for accommodating the bracket 6. A retaining mechanism 7 is provided between the bracket 6 and the housing 1, which includes a limiting component 71 and a release component 8. The limiting component 71 is coaxially arranged with the pivot. The limiting component 71 has a limiting seat 72 inside the bracket 6 and a plurality of limiting blocks 73 arranged in a circumferential array facing the housing 1. The limiting blocks 73 are inclined at an angle relative to the unfolding direction of the bracket 6. A reset structure 74 is provided between the limiting seat 72 and the bracket 6 on the side away from the housing 1. The limiting component 71 has a mating seat 75 on the housing 1 opposite to the limiting seat 72 and a limiting groove 76 that mates with the limiting blocks 73 is opened circumferentially. The release component 8 is connected to the side of the limiting seat 72 facing the mating seat 75 and extends out of the bracket 6 to form an operating member 84. Under the action of the operating member 84, the release component 8 pushes the limiting seat 72, causing the limiting blocks 73 to separate from the limiting groove 76. When the support 6 rotates in the unfolding direction, the limiting seat 72 is pushed into the support 6 by the cooperation of the tilt angle and the limiting groove 76, so that the support 6 can move freely in the unfolding direction.

[0022] The charging module 10 is disposed inside the housing and can store electrical energy and / or charge electrical devices; the charging module 10 is electrically connected to the first transmission line 2. When the housing 1 is magnetically fixed to the phone, the bracket 6 can be extended to a set angle to support the phone.

[0023] Specifically, the housing 1 can be made of a single piece of molded plastic or metal material, with an internal hollow mounting cavity formed by molding or processing to accommodate internal electronic components and mechanical structures. For example, the housing 1 can be formed by two interlocking upper and lower parts to create the internal mounting cavity.

[0024] The first transmission line 2 can be a USB-C cable with a USB-C plug at its first interface end 21, which can be plugged into power devices such as mobile phones and tablets for charging, or plugged into power adapters, power banks, or other power supply devices to charge the device itself. Alternatively, the first transmission line 2 can also be a Micro-USB or Lightning interface cable to accommodate the connection needs of different devices.

[0025] The rotating assembly 3 may include a central shaft and a turntable rotating around the central shaft. One end of the first transmission line 2 is fixed to the turntable, and the other end extends out of the housing 1. A spring is connected inside or outside the turntable. When the first transmission line 2 is pulled out, the spring is tightened and stores energy; when the first transmission line 2 is released, the spring force drives the turntable to rotate in the opposite direction, thereby automatically winding up the first transmission line 2. For example, the turntable may be a simple winding reel, and the spring is connected to the turntable through a gear set to achieve the automatic winding function.

[0026] The bracket 6 can be a flat structure connected to the side of the housing 1 via a pivot. The pivot can be a damping retainer 61, connected to the housing 1 with an interference fit, ensuring smooth rotation of the bracket 6. The housing 1 has a storage groove 13 corresponding to the size and shape of the bracket 6, allowing the bracket 6 to be neatly inserted when not in use. The retaining mechanism 7 can employ a simple friction fit structure, such as using a high-friction coefficient material on the contact surface between the bracket 6 and the housing 1, or using a spring-loaded ball bearing engaging a groove on the bracket 6 to provide sufficient friction or locking force when the bracket 6 is unfolded, ensuring stability at any angle.

[0027] The charging module 10 can consist of a built-in lithium-ion battery pack and corresponding charge / discharge management circuitry, housed within the housing 1. This module is electrically connected to the first transmission line 2 via wires, enabling it to charge itself or discharge to external devices through the first transmission line 2. Simultaneously, the charging module 10 is also electrically connected to the power supply terminal of the wireless charging module 9, providing operating power to the first wireless charging component 91 and the second wireless charging component 92. For example, the charging module 10 may include a power management chip responsible for battery charge / discharge control and output voltage stability.

[0028] When the housing 1 is magnetically attached to the back of the phone via the first wireless charging assembly 91, the user can flip and unfold the stand 6 from the storage slot 13. After unfolding, the bottom edge or a specific support point of the stand 6 contacts the tabletop, while the top edge or support surface of the stand 6 rests against the lower part of the phone, thus forming a stable triangular support structure that allows the phone to stand at a tilted angle for easier screen viewing. For example, the stand 6 can unfold to approximately 60 degrees, providing a comfortable viewing angle for the phone.

[0029] This embodiment provides a multi-mode magnetic charging device integrating a retractable data cable and a flip stand 6. By organically integrating the automatically retractable first transmission cable 2, the multi-device magnetic wireless charging module 9, and the adjustable-angle flip stand 6 into a compact housing 1, it effectively solves the problems of existing charging products being single-function, bulky, and inconvenient to carry. This device not only provides wired emergency charging capabilities but also enables simultaneous wireless charging and support for mobile phones and watches, greatly improving the convenience and user experience in scenarios involving charging and watching multiple devices.

[0030] This application further proposes a retaining mechanism 7, which includes a limiting component 71 and a releasing component 8. The limiting component 71 is coaxially arranged with the pivot between the housing 1 and the support 6. The limiting component 71 is configured to allow the support 6 to move automatically when it rotates in the unfolding direction, and to generate a locking interference when the support 6 is to rotate in the retracting direction, thereby preventing the support 6 from rotating back towards the housing 1. The releasing component 8 is linked to the limiting component 71 to release the locking interference, allowing the support 6 to rotate freely towards the housing 1 and be retracted.

[0031] The retaining mechanism 7 is a key structure used to ensure that the support 6 can stably remain at any angle set by the user after unfolding, and to prevent it from accidentally rotating or retracting. Its core function is to provide reliable positioning capability while also ensuring ease of operation. The limiting component 71 is the core component of the retaining mechanism 7, and its main function is to enable the support 6 to rotate freely in the unfolding direction and to lock in one direction in the retracting direction. This component is coaxially arranged with the axis of rotation between the housing 1 and the support 6, meaning that it works around the rotation center of the support 6, and its structure is compact and easy to integrate. The limiting component 71 can be implemented in various forms. For example, it can be designed with a structure with one-way ratchet or friction plate. When the support 6 rotates in the unfolding direction, the ratchet or friction plate can slide smoothly without obstruction; while when the support 6 attempts to rotate in the retracting direction, the ratchet or friction plate will immediately engage or generate sufficient friction force to form a locking interference, preventing the support 6 from rotating back to the housing 1 side. Another implementation involves the limiting component 71 comprising a series of inclined latches or protrusions. These latches can be pushed in or compressed when the bracket 6 is unfolded, and pop out and engage with corresponding structures on the housing 1 when the bracket 6 rotates, thus achieving one-way locking. The release component 8 works in conjunction with the limiting component 71, its function being to release the locking interference created by the limiting component 71 when the bracket 6 needs to be stored. Through the operation of the release component 8, the locking state of the limiting component 71 is temporarily released, allowing the bracket 6 to rotate freely towards the housing 1 and be stored. The release component 8 can be implemented in various ways; for example, it can be a push-button or toggle switch that uses a mechanical linkage mechanism to push open or disengage the locking component of the limiting component 71. Alternatively, it can be a lever structure hidden inside the bracket 6, which acts on the limiting component 71 when operated by the user, thus releasing it from locking.

[0032] Through the above technical solution, this application further proposes a retaining mechanism 7, which effectively solves the problems of inaccurate positioning of the bracket 6, inconvenient operation, and easy wear of damping components in the prior art through the ingenious cooperation of the limiting component 71 and the releasing component 8. Specifically, the limiting component 71 is coaxially arranged with the shaft between the housing 1 and the bracket 6, resulting in a compact structure that is easy to integrate. Its unique feature is that when the bracket 6 rotates in the unfolding direction, the limiting component 71 allows it to move automatically, and the user can easily adjust the bracket 6 to any desired unfolding angle without additional positioning operations. Once rotation stops, the limiting component 71 immediately generates locking interference when the bracket 6 attempts to rotate back in the retraction direction, thereby automatically and reliably fixing the bracket 6 at the current angle, meeting the personalized needs of the support angle in different usage scenarios. This design avoids the limitation of traditional rigid locking solutions that can only be positioned at a preset angle, and also overcomes the problem of performance degradation of damping components after long-term use. When it is necessary to retract the bracket 6, the user only needs to operate the releasing component 8, which will then work in conjunction with the limiting component 71 to release the locking interference, allowing the bracket 6 to smoothly rotate freely towards the housing 1 and be retracted. This unlocking mechanism avoids structural damage that may be caused by forced storage, improving user experience and device lifespan. Through the above technical solution, this application achieves reliable positioning of the bracket 6 at any unfolding angle, while ensuring the convenience and smoothness of storage operations, greatly enhancing the practicality and user satisfaction of the multi-mode magnetic charging device integrating the telescopic data cable and the flip bracket 6.

[0033] Through the above technical solution, this application provides a specific and reliable limiting component 71 structure. This structure relies on the ingenious cooperation between the limiting seat 72, limiting block 73, tilt angle, reset structure 74, mating seat 75, and limiting groove 76 to achieve free and smooth rotation of the bracket 6 in the unfolding direction and reliable locking in the folding direction. When the user needs to adjust the unfolding angle of the bracket 6, they only need to rotate the bracket 6 in the unfolding direction. The tilt angle on the limiting block 73 contacts the limiting groove 76 on the mating seat 75, and the resulting pushing force automatically pushes the limiting seat 72 into the bracket 6, releasing the lock. This allows the bracket 6 to move freely and unobstructed in the unfolding direction, and the user can easily adjust it to any desired angle without additional operation. Once the bracket 6 stops rotating, the reset structure 74 causes the limiting seat 72 to automatically pop out, and the limiting block 73 immediately engages in the nearest limiting groove 76, achieving immediate and stable position fixation. This design not only solves the problem of obstructed unfolding or locking failure of the bracket 6 in the prior art, but also ensures that the bracket 6 can reliably maintain its position at any unfolding angle, greatly improving the user experience and the practicality of the device.

[0034] In one embodiment of this application, the release component 8 includes a release element 81 and an operating element 84; Located within the bracket 6 and between the limiting seat 72 and the mating seat 75, the release member 81 includes a pressure ring 82 and a drive bar 83. The pressure ring 82 is connected to the outer periphery of the limiting seat 72, and the drive bar 83 is connected to the pressure ring 82. A reset guide is provided between the drive bar 83 and the bracket 6. It is connected to the drive bar 83 and passes through the bracket 6.

[0035] With the above technical solution, when the user needs to store the bracket 6, they only need to apply force through the operating component 84, which then transmits the force to the drive bar 83. Guided by the reset guide, the drive bar 83 stably pushes the pressure ring 82, which in turn acts evenly on the outer periphery of the limiting seat 72, pushing the limiting seat 72 out of the limiting groove 76 of the mating seat 75. Once the limiting seat 72 disengages from the limiting groove 76, the locking interference is released, and the bracket 6 can then freely rotate towards the housing 1 and be stored. When the user releases the operating component 84, the reset guide (e.g., an internal spring) will automatically reset the drive bar 83 and the pressure ring 82, allowing the limiting seat 72 to re-lock with the mating seat 75 when the bracket 6 is unfolded again. This design not only provides a reliable and smooth unlocking mechanism for the aforementioned limiting component 71, effectively solving the problem of inconvenient storage of the bracket 6, but also cleverly arranges the release component 81 within the bracket 6 and between the limiting seat 72 and the mating seat 75, making full use of the existing structural space and maintaining the compactness of the device. The design of the pressure ring 82 connecting to the outer periphery of the limiting seat 72 ensures a smooth and reliable unlocking process, avoiding jamming caused by localized force. The reset guide ensures smooth operation and automatic system reset, further enhancing the user experience. The operating component 84 protrudes from the bracket 6, allowing users to complete unlocking without complicated operations. The operation is intuitive and convenient, significantly improving the product's usability and user satisfaction.

[0036] In one embodiment of this application, the rotating assembly 3 is provided with a stop plate 31 relative to the housing 1, and the housing 1 is provided with a stop member 5 relative to the stop plate 31; The stop plate 31 is provided with an adjustment groove 32 relative to the stop member 5. The first end 51 of the stop member 5 is rotatably connected to the housing 1, and the second end 52 of the stop member 5 is slidably connected to the adjustment groove 32. The second end 52 is configured to have a tendency to rotate toward the inner wall of the adjustment groove 32 during movement. The adjusting groove 32 includes an outer sliding groove 33 and an inner sliding groove 34 arranged in sequence along the radial direction of the stop plate 31. The inner sliding groove 34 and the outer sliding groove 33 are connected by a reversing block 41. One end of the reversing block 41 is connected to the inner sliding groove 34, and the other end is connected to the outer sliding groove 33. The reversing block 41 is provided with a stop groove 42 on the side facing the receiving direction of the first transmission line 2. The stop groove 42 opens towards the outer sliding groove 33 and is provided with a guide channel 43 that connects to the inner sliding groove 34. When the rotating assembly 3 slowly retracts or extends the first transmission line 2, the second end 52 of the stop 5 slides freely in the inner slide groove 34; when the first transmission line 2 is quickly pulled out, the second end 52 enters the outer slide groove 33 through the reversing block 41 under the action of inertia; when the first transmission line 2 is released, the second end 52 slides along the outer slide groove 33 and is guided into the stop groove 42 to lock; when it is necessary to release the lock, the first transmission line 2 is pulled again, and the second end 52 is guided back into the inner slide groove 34 along the guide channel 43 to restore the free rotation state.

[0037] Through the above technical solution, this application provides a stop disc 31 on the rotating assembly 3 and a stop member 5 that cooperates with the stop disc 31 on the housing 1, and cleverly designs an adjustment groove 32 on the stop disc 31 to achieve the automatic locking function of the first transmission line 2 after it is pulled out to the required length. Specifically, when the user slowly retracts or extends the first transmission line 2, the second end 52 of the stop member 5 slides freely in the inner slide groove 34 of the adjustment groove 32, ensuring the smooth retraction and extension of the first transmission line 2. When the user quickly pulls out the first transmission line 2, the second end 52 of the stop member 5, under the action of inertia, switches from the inner slide groove 34 to the outer slide groove 33 through the reversing block 41. Once the first transmission line 2 is released, the rotating assembly 3 attempts to retract the line under the action of the spring force. At this time, the second end 52 of the stop member 5 slides along the outer slide groove 33 and is guided into the stop groove 42, thereby effectively locking the rotating assembly 3, preventing the first transmission line 2 from automatically retracting, and stably maintaining the required extension length. This design solves the problem in existing automatic cable retraction devices that cannot fix the cable length, resulting in a poor user experience. Furthermore, when unlocking is needed, the user simply pulls the first transmission line 2 again, and the second end 52 of the stop 5 will be guided back into the inner groove 34 along the guide channel 43, restoring its free rotation state, making unlocking simple and quick. The entire locking and unlocking process is achieved through the pulling action of the first transmission line 2, eliminating the need for additional operation buttons or complex mechanical structures, greatly improving user convenience and the device's intelligence. This integrated stop mechanism significantly improves the user experience of the retractable data cable without significantly increasing the device's size and complexity, enabling this multi-mode magnetic charging device to better adapt to different usage scenarios.

[0038] In one embodiment of this application, the inner groove 34 includes an adjustment section 35 and a sliding section 4. The diameter of the adjustment section 35 is larger than that of the sliding section 4, and it is connected to the outer wall of the reversing block 41. A guide section 36, which is connected to the sliding section 4, is formed by bending between the adjusting section 35 and the reversing block 41. When the first transmission line 2 is slowly extended or retracted, the second end 52 slides freely between the sliding section 4 and the adjusting section 35 through the guide section 36; when the first transmission line 2 is quickly pulled out, the second end 52 enters the outer slide groove 33 through the commutator block 41 under the action of inertia.

[0039] Through the above technical solution, this application significantly optimizes the movement path of the second end 52 of the stop member 5 at different retraction and extension speeds of the first transmission line 2 by designing the inner slide groove 34 in a segmented structure, namely by introducing an adjustment section 35, a sliding section 4, and a guide section 36. When the first transmission line 2 is slowly retracted or extended, the second end 52 of the stop member 5 slides smoothly between the larger diameter adjustment section 35 and the smaller diameter sliding section 4 through the curved guide section 36. The guiding effect of the guide section 36 ensures that the second end 52 always moves within the inner slide groove 34, effectively avoiding the problem of premature locking caused by accidentally entering the outer slide groove 33, thereby improving the smoothness and reliability of the telescopic retraction mechanism at low speeds. When the first transmission line 2 is quickly pulled out, the second end 52 of the stop member 5 gains sufficient inertia, which is enough to overcome the constraint of the guide section 36. In other words, under the action of inertia, the second end 52 does not have time to turn into the guide section 36, but directly enters the outer slide groove 33 through the reversing block 41, thereby accurately triggering the locking function. This design solves the problem of locking function failure caused by insufficient inertia or unclear path in traditional structures. Overall, through the refined segmented design of the inner slide groove 34, this application achieves stability and accuracy of the telescopic cable retraction locking mechanism at different operating speeds, greatly improving the user experience and avoiding the problems of accidental locking and inability to lock. This significantly enhances the practicality and reliability of the multi-mode magnetic charging device integrating the telescopic data cable and the flip bracket 6.

[0040] In one embodiment of this application, a second transmission line 22 electrically connected to the charging module 10 and having a second interface end 23 is also included. The housing 1 is provided with a wire outlet hole, a limiting hole, and a wire release hole relative to the second transmission line 22. When the second interface end 23 is fixed to the housing 1, a hanging rope structure is formed between the wire outlet hole and the limiting hole of the second transmission line 22.

[0041] Through the above technical solution, this application adds a second transmission line 22 with a second interface end 23 to the existing charging device integrating multiple charging functions, which is electrically connected to the charging module 10. This adds an extra wired charging interface to the device, enabling it to charge more types of electrical devices simultaneously, thus improving the device's compatibility and meeting the needs of simultaneous wired charging of multiple devices. Simultaneously, the housing 1 is provided with a cable outlet hole, a limiting hole, and a cable release hole corresponding to the second transmission line 22, providing positioning and guidance for the routing of the second transmission line 22. This allows the second transmission line 22 to be arranged according to a preset path, providing a structural basis for forming a hanging rope structure. When the second interface end 23 is fixed on the housing 1, the second transmission line 22 will naturally form a lanyard structure between the outlet hole and the limiting hole, which can be held or hung. The second transmission line 22, which was originally used for charging, is reused as a lanyard. There is no need to add an additional independent lanyard component. This will not increase the overall size of the device too much, maintain the miniaturized and integrated design of the device, and avoid the problem of easy loss of the lanyard if it is configured separately. At the same time, it meets the dual needs of expanding the wired charging interface and convenient carrying and hanging when going out, effectively improving the practicality of the device.

[0042] In one embodiment of this application, at least two receiving grooves 11 are provided on the outer side of the housing 1. The first interface end 21 and the second interface end 23 are accommodated in the corresponding receiving grooves 11. The receiving grooves 11 are provided with arc-shaped guide surfaces to guide the movement of the first interface end 21 or the second interface end 23.

[0043] By providing at least two receiving slots 11 on the outside of the housing 1, and having the first interface end 21 and the second interface end 23 respectively accommodated within their respective receiving slots 11, the problems of exposed interface ends being easily damaged, easily contaminated with dust, and affecting the overall aesthetics of the device are effectively solved. With the interface ends properly stored, the risk of physical damage is significantly reduced, while preventing dust from entering the interface and affecting charging performance, resulting in a cleaner, more organized appearance and easier portability and storage. Furthermore, the receiving slots 11 are equipped with arc-shaped guide surfaces to guide the movement of the first interface end 21 or the second interface end 23. This design greatly improves the ease of use for users to retrieve the interface ends. The arc-shaped guide surfaces provide a smooth path for force application, avoiding the difficulty of retrieving the interface end once it is completely embedded in the receiving slot 11, making the retrieval process smoother and less strenuous. In particular, when the first transmission line 2 is automatically retracted via the rotating component 3, the first interface end 21 can be magnetically absorbed and housed in the receiving groove 11, which is convenient and quick. Furthermore, the second interface end 23 of the second transmission line 22, forming a hanging rope structure, is stably fixed to the receiving groove 11 via a slot or other means, further enhancing the reliability of the hanging rope. Overall, this technical solution significantly optimizes the user experience while protecting the interface end and improving the aesthetics of the device.

[0044] In one embodiment of this application, a wireless charging module 9 electrically connected to the charging module 10 is further included; it includes at least a first wireless charging component 91 and a second wireless charging component 92. The first wireless charging component 91 is disposed on the side of the housing 1 opposite to the bracket 6, and the housing 1 can be magnetically fixed to the mobile phone by means of the first wireless charging component 91; the second wireless charging component 92 is disposed on the bracket 6, and the second wireless charging component 92 can magnetically fix the watch to the bracket 6. The wireless charging module 9 may include two independent wireless charging coils and corresponding control circuits. The coil and magnet array of the first wireless charging component 91 are integrated on the side of the housing 1 opposite to the bracket 6. When the phone is close, it is magnetically attracted and wirelessly charged. The coil and magnet of the second wireless charging component 92 are integrated on the surface of the bracket 6 for attracting and wirelessly charging small wearable devices such as smartwatches. For example, the first wireless charging component 91 may use the Qi standard, and the second wireless charging component 92 may use the WPC standard or a charging protocol specific to a particular watch brand.

[0045] In one embodiment of this application, the housing 1 further includes a first outer shell 12, a second outer shell 15, and a third outer shell 16; The first outer shell 12 and the second outer shell 15 are detachably connected to each other and form an installation cavity. The storage groove 13 is recessed on the side of the first outer shell 12 away from the second outer shell 15. The third housing 16 is detachably connected to the side of the second housing 15 away from the first housing 12 and forms a storage cavity for storing the first wireless charging component 91.

[0046] Through the above technical solution, this application divides the housing 1 into three detachable and independently connected parts, effectively solving the inconvenience of traditional integrated housing 1 structures in terms of assembly, production, and subsequent maintenance. The first outer shell 12 and the second outer shell 15 are detachably connected to form an installation cavity, allowing core internal components such as the rotating component 3 and the charging module 10 to be pre-installed on one of the outer shells. After pre-installation, the entire assembly is then connected, greatly improving the convenience of assembly and production. At the same time, when internal components need to be inspected and maintained, the outer shell can be easily disassembled without damaging the overall structure of the device. The storage slot 13 is recessed on the side of the first outer shell 12 opposite to the second outer shell 15, making reasonable use of the outer space of the housing 1 and avoiding positional conflicts between the structure of the storage bracket 6 and other components inside the housing. Furthermore, the third outer shell 16 is detachably connected to the side of the second outer shell 15 opposite to the first outer shell 12, forming a storage cavity for housing the first wireless charging component 91. This not only ensures that the first wireless charging component 91 can be positioned on the side of the shell 1 opposite to the bracket 6 to achieve the function of magnetically fixing the phone, but also allows for independent storage, avoiding interference with the arrangement of core components inside the shell. This split design allows users to disassemble and maintain the first wireless charging component 91 separately without disassembling the entire shell 1, further improving maintenance convenience. Overall, this solution, through the precise structural disassembly of the shell 1, achieves a reasonable division of different functional areas, effectively avoiding positional interference between components, making the device structure more compact and orderly, and significantly improving production efficiency and maintenance convenience.

[0047] In one embodiment of this application, the storage slot 13 is provided on the side of the first outer shell 12 away from the second outer shell 15, and the first outer shell 12 is provided with a relief slot 14 communicating with the storage slot 13. The relief slot 14 is located at the rotating end of the storage slot 13 away from the bracket 6. The bracket 6 is equipped with an operating section relative to the storage slot 13.

[0048] Through the above technical solution, when the bracket 6 is fully retracted into the storage slot 13, the clearance slot 14, located at the end of the storage slot 13 away from the rotating end of the bracket 6, provides a space for the user's fingers or fingernails to enter, allowing the user to easily access the free end of the bracket 6. Simultaneously, the operating part on the bracket 6 provides the user with a clear point of force application, allowing the user to directly apply force to the operating part, thus avoiding slippage on a smooth surface. This design allows the user to easily rotate and unfold the bracket 6 from the storage slot 13, greatly improving the ease of unfolding the bracket 6. Furthermore, this structural design effectively solves the problem of the bracket 6 being difficult to remove while ensuring the overall flatness of the device, balancing product practicality and user experience.
