[0038] This embodiment of the present application provides a mobile phone case 10, see Figures 1 to 5 The mobile phone case 10 includes a case body 1 and a data cable box 2. The case body 1 includes a first accommodating cavity 11, which is used to accommodate a mobile phone. The data cable box 2 is arranged on the case body 1. The data cable box 2 includes a main body 21, a rotating member 22 and a data cable 23. The main body 21 has a second accommodating cavity 211, and the rotating member 22 is rotatably arranged in the second accommodating cavity 211. At least a portion of the data cable 23 is wound around the circumferential outer side of the rotating member 22, and both ends are arranged on the outer side of the second accommodating cavity 211. The data cable 23 can be unwound from the rotating member 22 so that at least one end of the data cable 23 moves in a direction away from the second accommodating cavity 211.

[0039] The main body 1 is the main structure of the mobile phone case 10. Its core function is to wrap and protect the mobile phone, providing basic protection for it. The main body 1 can closely fit the contours of the mobile phone, thereby effectively preventing the mobile phone from being damaged by collisions, scratches, etc.

[0040] The first accommodating cavity 11 is a space located inside the shell body 1. Its shape and size are precisely adapted to the mobile phone, so that the mobile phone can be properly placed therein, playing a role in stabilizing the position of the mobile phone and ensuring that the mobile phone will not shake or shift randomly in the shell.

[0041] The data cable box 2 is a functional module integrated on the mobile phone case 10, which is mainly used to store and manage the data cable 23, so that the user can use the data cable 23 to perform charging, data transmission and other operations when needed, while effectively avoiding the problem of messy placement of the data cable 23.

[0042] The main body 21 is the core structural support of the data cable box 2. The second accommodating cavity 211 within it is a key space for the entire data cable 23 storage system. It provides a place for the rotating member 22 and a portion of the data cable 23, allowing the data cable 23 to be wound and unwound in a relatively closed and orderly environment. It also provides a certain degree of protection for these internal components, preventing unnecessary interference or damage from external factors. The specific structure of the main body 21 is not limited here.

[0043] For example, the main body 21 and the second accommodating cavity 211 may be designed to be circular, elliptical, or rectangular in shape to accommodate the winding requirements of the rotating member 22 and the data cable 23 of different lengths and diameters.

[0044] In some embodiments, the outer shell of the main body 21 can be made of transparent or translucent material to facilitate the user to observe the remaining length and winding status of the internal data cable 23. In addition, the main body 21 can be integrally formed with the shell body 1 to enhance the stability of the overall structure.

[0045] The rotating member 22 is disposed in the second accommodating cavity 211 of the main body 21 and is capable of rotating around a certain axis. The circumferential outer side of the rotating member 22 is where the data cable 23 is wound. When the data cable 23 is needed, the rotating member 22 can rotate to unwind the data cable 23, allowing at least one end of the data cable 23 to move smoothly in a direction away from the second accommodating cavity 211, thereby extending a sufficient length for connection to an external device (such as a charger, computer, etc.). After the data cable 23 is used, it can be rewound back onto the rotating member 22 by rotating in the opposite direction, thereby achieving storage and organization of the data cable 23.

[0046] The data cable 23 connects the phone to an external power source or other device, enabling functions such as charging, data synchronization, and file transfer. The data cable 23 is partially wound around the rotating member 22 and can be unwound from the rotating member 22 to a specific length as needed. Both ends of the data cable 23 are located outside the second accommodating cavity 211 to facilitate connection with the phone and external device.

[0047] The material of the data line 23 can be selected from highly elastic and wear-resistant materials to increase its service life.

[0048] The two ends of the data cable 23 can be equipped with different types of interfaces, such as a Lightning interface or type-c interface suitable for mobile phone charging and data transmission at one end, and a standard USB-A interface or other commonly used external device connection interface at the other end to meet the user's usage needs in different scenarios.

[0049] The mobile phone case 10 provided in the embodiment of the present application adopts a winding design, which winds part of the data cable 23 around the circumferential outer side of the rotating member 22 and stores it in the second accommodating cavity 211 of the data cable box 2. This keeps the data cable 23 neat and orderly, reducing the wear and tear on the data cable 23 caused by being exposed to the outside. The data cable box 2 is integrated into the case body 1, and the data cable 23 can be unwound from the rotating member 22. When the data cable 23 is needed, the user only needs to pull out the corresponding length of data cable 23 from the data cable box 2 to connect the mobile phone and external devices. The user no longer needs to carry and organize the data cable 23 separately, which is conducive to improving the convenience of use. At the same time, the mobile phone case 10 not only has the function of protecting the mobile phone, but also integrates the function of storing and conveniently using the data cable 23, increasing the added value and practicality of the product, and meeting the user's demand for multifunctional mobile phone peripheral products.

[0050] In some embodiments, see Figures 1 to 5 The data cable 23 includes a first connecting section 231 and a second connecting section 232. The first connecting section 231 is connected to the main body 21, and the second connecting section 232 is electrically connected to the first connecting section 231. The second connecting section 232 is wound around the circumferential outer side of the rotating member 22. The second connecting section 232 can be unwound from the rotating member 22 and moved in a direction away from the second accommodating cavity 211.

[0051] As part of the data line 23, the first connecting section 231 serves to establish a connection path between the main body 21 and the subsequent circuit structure. One end of the first connecting section 231 is firmly connected to the main body 21, presenting a relatively fixed state in the overall structural layout.

[0052] The connection method between the first connecting section 231 and the main body 21 is not limited here. For example, welding, snap connection or use of a special connection plug can be used to ensure that the connection is stable and reliable, thereby effectively transmitting current and data signals.

[0053] In some embodiments, a corresponding interface protection structure may be provided at the portion where the main body 21 is connected to the first connecting section 231 , such as a rubber sleeve or a plastic protective shell, to prevent the connection portion from being damaged due to external pulling or friction.

[0054] The second connecting section 232 is another important component of the data cable 23. It is electrically connected to the first connecting section 231 and is the core portion that can be wound around the circumference of the rotating member 22. During use, the rotating member 22 rotates to unwind the cable, allowing it to extend to a certain length for connection to an external device (such as a charger or computer) for charging and data transmission.

[0055] The fixed connection between the first connecting section 231 and the main body 21, and the winding design of the second connecting section 232 on the rotating member 22, by dividing the data cable 23 into two sections and allowing the second connecting section 232 to be unwound from the rotating member 22, allow users to flexibly adjust the length of the data cable 23 according to actual usage scenarios. This greatly improves the flexibility and convenience of using the data cable 23, effectively adapting to the connection requirements of devices at different distances.

[0056] In some embodiments, the first connecting segment 231 and the second connecting segment 232 are wound around the circumferential outer side of the rotating member 22. The first connecting segment 231 and the second connecting segment 232 can be unwound from the rotating member 22 and move away from the second accommodating cavity 211.

[0057] Here, both the first connecting section 231 and the second connecting section 232 have the characteristic of being wound around the outer side of the rotating member 22 in the circumferential direction.

[0058] In some embodiments, there is only one rotating member 22, which has a multi-layered cable trough structure. For example, an outer cable trough is used to wind the second connecting segment 232, while an inner cable trough is used to wind the first connecting segment 231. This design allows the two data cable segments 23 to be relatively independent during the winding process, reducing the risk of mutual interference and entanglement. The inner wall of the cable trough can be made of a smooth material or have a lubricating coating to reduce friction between the data cable 23 and the cable trough during winding and unwinding, ensuring smoother operation.

[0059] In some embodiments, there are two rotating members 22, with the first connecting segment 231 and the second connecting segment 232 being wound around their respective corresponding rotating members 22. The two rotating members 22 can rotate independently of each other, allowing the first connecting segment 231 and the second connecting segment 232 to be wound or unwound independently. Alternatively, the two rotating members 22 can rotate in tandem, allowing the first connecting segment 231 and the second connecting segment 232 to be wound or unwound simultaneously.

[0060] In some embodiments, a wire organizing rack is provided in the connection area between the main body 21 and the rotating member 22. When the first connecting segment 231 or the second connecting segment 232 is unwound from the rotating member 22, the organizing rack can comb and guide it to ensure that the first connecting segment 231 or the second connecting segment 232 moves in an orderly manner in a direction away from the second accommodating cavity 211 to avoid collision or entanglement with other components.

[0061] Because both the first connecting section 231 and the second connecting section 232 can be unwound from the rotating member 22, the user has more options and more flexibility when using the data cable 23. Regardless of the relative orientation of the phone's interface and the external device, a convenient connection can be achieved by unwinding the appropriate connecting section.

[0062] In some embodiments, see Figures 1 to 5 The main body 21 includes a first electrical connector 212 and a second electrical connector 213. The first electrical connector 212 is electrically connected to the first connecting section 231, and the second electrical connector 213 is electrically connected to the second connecting section 232. The first electrical connector 212 and the second electrical connector 213 can move with the relative movement of the first connecting section 231 and the second connecting section 232.

[0063] The first electrical connector 212 is a component within the main body 21 that establishes an electrical connection with the first connecting section 231. As a key node for transmitting current and data signals between the main body 21 and the first connecting section 231, it must have good conductivity and stability to ensure the quality and efficiency of signal transmission.

[0064] The second electrical connector 213 is a component of the main body 21 that is electrically connected to the second connecting section 232. Similar to the first electrical connector 212, it is responsible for establishing a stable electrical pathway between the main body 21 and the second connecting section 232, allowing data and power to be transmitted smoothly between the two. It serves as an indispensable bridge in the electrical connection system between the data cable 23 and the phone case 10.

[0065] The first electrical connector 212 and the second electrical connector 213 can move with the relative movement of the first connecting section 231 and the second connecting section 232 to adapt to the position changes of the first connecting section 231 and the second connecting section 232 during the unwinding and winding process to ensure the continuity of the electrical connection.

[0066] For example, the first electrical connector 212 and the second electrical connector 213 can be mounted on a slidable or rotatable bracket. When the first connecting segment 231 or the second connecting segment 232 is unwound, the corresponding electrical connector can move or rotate smoothly on the bracket, preventing the electrical connection point from loosening or being damaged due to the pulling of the connecting segment.

[0067] In some embodiments, in order to prevent the electrical connector from colliding with or short-circuiting other components inside the main body 21 during movement, an insulating protective sleeve or an isolation baffle may be provided around the electrical connector to ensure the safety and reliability of its movement.

[0068] The main body 21 establishes connections with the first connecting segment 231 and the second connecting segment 232 respectively through the first electrical connector 212 and the second electrical connector 213. The first electrical connector 212 and the second electrical connector 213 can move with the relative movement of the first connecting segment 231 and the second connecting segment 232 to adapt to the position changes of the first connecting segment 231 and the second connecting segment 232 during the unwinding and winding process, so that the first connecting segment 231 and the second connecting segment 232 always maintain a good contact state during the relative movement, effectively avoiding charging interruption caused by loose or interrupted connection, thereby ensuring the continuity of the electrical connection.

[0069] In some embodiments, see Figures 1 to 5 The first electrical connector 212 includes a first circuit board 2121, which is provided with an annular contact groove 2122. The second electrical connector 213 includes a second circuit board 2131, which is arranged opposite the first circuit board 2121. The second circuit board 2131 is provided with a contact member 2132 extending toward the first circuit board 2121. The contact member 2132 extends into the contact groove 2122 and is electrically connected to the contact groove 2122. The second electrical connector 213 is mounted on the rotating member 22. The rotating member 22 rotates to drive the contact member 2132 to rotate relative to the contact groove 2122.

[0070] The contact groove 2122 is an annular structure located on the first circuit board 2121 , and its shape and size are adapted to the contact member 2132 , and is used to accommodate the contact member 2132 and ensure stable electrical contact in various relative motion states.

[0071] The inner wall material of the contact groove 2122 generally has good electrical conductivity and wear resistance to ensure long-term stable signal transmission and reduce loss caused by friction.

[0072] The contact member 2132 is a component mounted on the second circuit board 2131 and extending toward the first circuit board 2121 . Its main function is to cooperate with the contact slot 2122 to achieve electrical connection.

[0073] The contact piece 2132 has certain elastic properties. The contact piece 2132 can smoothly extend into the contact groove 2122 and maintain good contact pressure to ensure electrical conduction. It must also be able to adapt to relative movement during rotation and will not be easily damaged or disengaged due to friction or vibration.

[0074] In some embodiments, the first circuit board 2121 and the second circuit board 2131 ensure the accuracy and stability of their relative positions through structures such as positioning columns or card slots 227 set in the main body 21, preventing displacement when the mobile phone case 10 is subjected to external force impact or vibration during daily use, thereby preventing the electrical connection performance from being affected.

[0075] In some embodiments, the interior of the contact slot 2122 may be provided with small protrusions or grooves. These structures can increase the contact area and friction, further improving the stability and reliability of the electrical connection. The end of the contact member 2132 may employ a resilient contact design, such as a metal spring or elastic rubber wrapped around a metal conductor. This allows the resilient contact to maintain close contact with the inner wall of the contact slot 2122 even if there is a certain gap or position deviation during rotation, ensuring that signal transmission is not affected.

[0076] The connection method between the rotating member 22 and the second electrical connector 213 (i.e., the second circuit board 2131) is not limited herein. For example, the second circuit board 2131 can be mounted on the central axis of the rotating member 22 by fixing the central axis. This allows the rotation of the rotating member 22 to directly drive the second circuit board 2131 and the contact member 2132 thereon to rotate about the axis, achieving relative rotational motion with the contact slot 2122 on the first circuit board 2121. Furthermore, a bearing or sleeve structure can be provided at the connection between the rotating member 22 and the main body 21 to reduce friction and wear during rotation, extend the service life of the rotating member 22, and ensure a smoother and more fluid rotation process.

[0077] In some embodiments, to prevent impurities such as dust and moisture from entering the connection area between the contact groove 2122 and the contact member 2132, a protective structure such as a sealing rubber ring or a sealing cover can be provided around the connection area. These protective structures not only keep the connection area clean, preventing problems such as short circuits or poor contact caused by impurities, but also protect the circuit board and the contact member 2132 from oxidation and corrosion to a certain extent, thereby improving the durability of the entire electrical connection system.

[0078] The coordinated design of the annular contact groove 2122 and the contact member 2132 maintains a stable electrical connection during relative motion between the first connecting segment 231 and the second connecting segment 232 (particularly during the relative motion of the rotating member 22, which in turn drives the second connecting segment 232). This helps prevent loose connections or interruptions caused by movement, ensuring continuity and reliability during charging and data transmission, and providing a solid foundation for the normal use of the phone.

[0079] In some embodiments, see Figures 1 to 5 The main body 21 is provided with a rotating shaft 214. The rotating member 22 includes an axially extending mounting area 221 and a circumferentially extending winding area 222. The rotating shaft 214 passes through the mounting area 221. The rotating member 22 rotates around the rotating shaft 214 to allow the data cable 23 to be wound around the winding area 222.

[0080] The rotating shaft 214 is a rotating shaft structure set on the main body 21. It provides a central axis and support point for the rotating part 22, so that the rotating part 22 can perform stable circular motion around it. It is the key hub for realizing the winding and unwinding functions of the data cable 23. Its material usually has sufficient strength and wear resistance to ensure long-term stable rotation performance.

[0081] The connection method between the rotating shaft 214 and the main body 21 is not limited herein. For example, the rotating shaft 214 can be integrally formed with the main body 21, thereby enhancing the stability and integrity of the entire structure. Alternatively, a detachable connection method, such as a threaded or snap-fit ​​connection, can be employed to facilitate replacement or repair of the rotating member 22 or the rotating shaft 214 in the event of damage. A bearing or sleeve structure can be provided at the connection between the rotating shaft 214 and the main body 21 to further reduce friction during rotation, ensuring smoother rotation, while also reducing wear and extending the service life of the rotating shaft 214 and the main body 21.

[0082] The mounting area 221 is a specific area extending axially on the rotating member 22. Its main function is to cooperate and connect with the rotating shaft 214 of the main body 21. Through appropriate hole diameter and shape design, it is ensured that the rotating member 22 can be accurately installed on the rotating shaft 214 and can rotate freely around the rotating shaft 214. The structure and size of the mounting area 221 need to be precisely matched with the rotating shaft 214 to reduce shaking and friction during rotation.

[0083] A lubricating device, such as lubricating oil or a solid lubricant, can be installed inside the mounting area 221 to reduce the friction coefficient with the rotating shaft 214 and improve rotation efficiency and flexibility. Limiting structures can be designed at both ends of the mounting area 221 to prevent axial displacement of the rotating member 22 and ensure its stability and safety during rotation.

[0084] The winding area 222 is the circumferentially extending portion of the rotating member 22 where the data cable 23 is actually wound. Its shape and size are designed based on factors such as the diameter, length, and winding method of the data cable 23. It typically has a certain curvature and width to ensure that the data cable 23 can be wound neatly and tightly around it and that the desired length of data cable 23 can be smoothly released during the unwinding process.

[0085] In some embodiments, the surface of the winding area 222 may be designed with some grooves or raised lines, which can guide the winding direction of the data line 23, making the data line 23 more orderly during the winding process and avoiding cross winding or looseness.

[0086] In some embodiments, a protective baffle can be set at the edge of the winding area 222 to prevent the data cable 23 from accidentally slipping off the winding area 222 during the winding and unwinding process. At the same time, it can also provide certain protection for the data cable 23 and reduce damage caused by collision or friction.

[0087] The coordinated design of the rotating shaft 214 and the mounting area 221 of the rotating member 22 enables the rotating member 22 to rotate stably about the rotating shaft 214, thereby achieving efficient winding and unwinding of the data cable 23 in the winding area 222. This structural design precisely controls the winding and unwinding process of the data cable 23, ensuring that the desired length of data cable 23 can be quickly and accurately obtained each time the data cable 23 is used, thereby improving the convenience and efficiency of the user's use of the data cable 23. Furthermore, the stable rotation structure reduces the risk of wear or damage to the data cable 23 caused by unstable rotation, thereby extending the service life of the data cable 23.

[0088] In some embodiments, see Figures 1 to 5 A spring 24 is installed in the mounting area 221, and the rotating shaft 214 passes through the spring 24. The ends of the spring 24 are fixed to the sidewalls of the mounting area 221 and the rotating shaft 214, respectively. When the data cable 23 is unwound from the rotating member 22, the spring 24 undergoes elastic deformation. The spring 24 recovers its elastic deformation, and the data cable 23 rewinds under the elastic force of the spring 24.

[0089] The spring 24 is a device that stores elastic potential energy and is typically made of a highly elastic metal material, such as carbon steel or stainless steel. In the case 10, the spring 24 is located within the mounting area 221 of the rotating member 22. Using its elastic deformation properties, the spring 24 assists in controlling the winding and unwinding of the data cable 23, making it a key component in enabling the automatic winding of the data cable 23.

[0090] The side wall of the installation area 221 is the surrounding boundary portion of the installation area 221 of the rotating part 22. It provides a fixed support point for the mainspring 24, so that the mainspring 24 can be stably installed and work in the installation area 221. Together with the rotating shaft 214, it constitutes a fixed structural system of the mainspring 24, ensuring that the mainspring 24 always remains in the predetermined position and direction during the process of elastic deformation and deformation recovery.

[0091] One end of spring 24 is secured to the sidewall of mounting area 221 by welding, riveting, or by using a dedicated securing slot 227, ensuring a secure and stable connection that prevents loosening or displacement during deformation of spring 24. The other end of spring 24 is secured to shaft 214, also ensuring a secure connection to effectively drive spring 24 to elastically deform as shaft 214 rotates.

[0092] In some embodiments, a guiding structure, such as a guide rail or a limit groove, is provided in the installation area 221 to guide the extension and contraction direction of the mainspring 24 during the deformation process, thereby avoiding abnormal conditions such as twisting or winding of the mainspring 24 and further improving its working stability and reliability.

[0093] Furthermore, the spring constant of the mainspring 24 can be appropriately selected based on the characteristics of the data cable 23 (such as length, thickness, and material) and the overall design requirements of the phone case 10. If the spring constant is too high, the data cable 23 may need to overcome significant resistance when unwinding, making it more laborious to use. On the other hand, if the spring constant is too low, the automatic rewinding function of the data cable 23 may not be effectively achieved, causing the data cable 23 to become loose easily. Therefore, by accurately calculating and experimentally testing, selecting the appropriate spring constant for the mainspring 24 can achieve the optimal performance balance for the entire data cable 23 winding system.

[0094] By disposing the spring 24 within the mounting area 221 and utilizing the spring's elastic deformation and recovery properties, the data cable 23 automatically rewinds. After using the data cable 23, the user need not manually rewind the data cable 23 onto the rotating member 22. Instead, the user simply releases the data cable 23, and the spring 24 automatically rewinds the data cable 23 as it recovers its elastic deformation. This significantly improves ease of use and reduces the tedious task of organizing the data cable 23. It also avoids problems such as tangling, damage, or loss of the data cable 23 caused by the user forgetting to rewind the data cable 23.

[0095] In some embodiments, see Figures 1 to 5The end surface of the rotating member 22 is provided with an inner groove 223 and an outer groove 224 spaced apart and in an annular shape, as well as an inlet 225 and an outlet 226 communicating with the inner groove 223 and the outer groove 224. The outlet 226 is provided with a latching slot 227. The main body 21 is provided with a positioning member 25, which includes a seat 251 and a positioning protrusion 252. The seat 251 is rotatably disposed on the main body 21, and the positioning protrusion 252 protrudes from the end surface of the seat 251. The positioning protrusion 252 slides along the inner groove 223 and the outer groove 224, and the positioning protrusion 252 can be latched in the latching slot 227 to limit the rotational position of the rotating member 22 relative to the main body 21.

[0096] The inner groove 223 is an annular groove structure provided on the end surface of the rotating member 22, located relatively close to the center of rotation. It is spaced apart from the outer groove 224 and serves primarily to provide a sliding track for the positioning protrusion 252 of the positioning member 25. By cooperating with the positioning protrusion 252, the rotational position of the rotating member 22 is defined and guided.

[0097] The outer groove 224 is also an annular groove on the end surface of the rotating member 22, located relatively far from the center of rotation. Together with the inner groove 223, it forms a sliding path for the positioning protrusion 252. The spacing and annular shapes of the outer and inner grooves 224 and 223 enable the positioning protrusion 252 to slide on tracks of varying radii, thereby meeting the requirements of different rotational position limits.

[0098] The inner wall of the chute can be made of a smooth, wear-resistant material, such as specially treated plastic or metal coating. This can reduce friction on the positioning protrusion 252 during sliding, making sliding smoother and extending the service life of the chute and positioning protrusion 252. In addition, the depth and width of the chute can be precisely designed based on the dimensions of the positioning protrusion 252 to ensure that the positioning protrusion 252 can slide stably within it, while also avoiding situations where it is too loose, resulting in inaccurate positioning, or too tight, affecting sliding flexibility.

[0099] The inlet 225 is provided on the end surface of the rotating member 22 and is a passage portion for the positioning protrusion 252 to smoothly enter the inner and outer chutes 223, 224. It connects the inner and outer chutes 223, 224, allowing the positioning protrusion 252 to accurately enter the corresponding chutes during initial installation or in certain specific circumstances, and begin its sliding stroke within the chutes.

[0100] The outlet 226 is a portion on the end surface of the rotating member 22 corresponding to the inlet 225 , and is a passage for the positioning protrusion 252 to slide out of the inner sliding groove 223 and the outer sliding groove 224 .

[0101] A slot 227 is provided at the outlet 226. When the positioning protrusion 252 slides here, it may be stuck in the slot 227, thereby achieving precise limitation of the rotation position of the rotating member 22, preventing it from continuing to rotate or fixing it at a specific rotation angle position.

[0102] Guide slopes or chamfers may be provided at the entrance 225 and the exit 226. When the positioning protrusion 252 enters the entrance 225, the guide slopes help it enter the chute more smoothly, reducing possible jamming. At the exit 226, the chamfers allow the positioning protrusion 252 to slide out of the chute and into the engaging slot 227 more naturally and smoothly, thereby improving the success rate and accuracy of the engagement.

[0103] The latching groove 227 is a recessed structure located at the outlet 226. Its shape and size match the positioning protrusion 252, and it can accommodate the positioning protrusion 252 and fix the positioning protrusion 252 through a snap action. The presence of the latching groove 227 allows the rotating member 22 to be accurately positioned at the desired position, ensuring the relative position stability of the rotating member 22 with respect to the main body 21.

[0104] The positioning member 25 is a component consisting of a seat portion 251 and a positioning protrusion 252 , and is integrally mounted on the main body 21 , and is used to position and limit the rotational position of the rotating member 22 .

[0105] The seat portion 251 serves as a supporting structure for the positioning protrusion 252 and is rotatably disposed on the main body portion 21 , providing basic support and rotational flexibility for the movement of the positioning protrusion 252 .

[0106] The connection between the seat 251 and the main body 21 can be achieved in a variety of ways to achieve a rotatable function, such as by providing a small bearing or sleeve structure, installing the seat 251 on the bearing or sleeve, so that the seat 251 can rotate flexibly around the axis and can withstand a certain lateral force to ensure that there will be no loosening or deviation during the rotation process.

[0107] The positioning protrusion 252 is the part that directly interacts with the inner slide groove 223 , the outer slide groove 224 and the clamping groove 227 , and controls the rotational position of the rotating member 22 by sliding in the slide groove and engaging with the clamping groove 227 .

[0108] The inner chute 223, outer chute 224, inlet 225, and outlet 226 on the end surface of the rotating member 22 form a relatively complete positioning and guidance system. The annular shape of the inner and outer chute 223 and 224 ensures that the positioning protrusion 252 can slide in a circular motion around the center of the rotating member 22, simulating rotation at different angular positions. The rational arrangement of the inlet 225 and outlet 226 allows the positioning protrusion 252 to easily enter and exit the chute system, ensuring the consistency and operability of the entire positioning process.

[0109] The positioning protrusion 252 protrudes from the end surface of the seat 251. Its shape not only aligns with the inner groove 223, the outer groove 224, and the latching slot 227, but can also be provided with some elastic structure, such as a small rubber spring head or a metal spring. When the positioning protrusion 252 is engaged with the latching slot 227, these elastic structures provide a certain elastic buffer, preventing damage to the latching slot 227 or the positioning protrusion 252 due to overtightening. They also enhance the stability of the engagement to a certain extent, ensuring that the rotating member 22 is firmly fixed in the limited position.

[0110] The coordinated design of the inner slide groove 223, the outer slide groove 224, the positioning protrusion 252, and the latching slot 227 enables precise definition of the rotational position of the rotating member 22 relative to the main body 21. Whether the data cable 23 needs to be wound to a specific length and the position of the rotating member 22 needs to be fixed, or in other application scenarios where the rotating member 22 needs to be maintained at a specific angle, this can be achieved by accurately snapping the positioning protrusion 252 into the latching slot 227. This ensures the accuracy and stability of the rotation of the rotating member 22, thereby ensuring that the winding and unwinding operations of the data cable 23 can be carried out as expected. For example, the length of the data cable 23 can be accurately controlled, avoiding problems such as excessive winding or unwinding of the data cable 23 due to the random rotation of the rotating member 22.

[0111] In some embodiments, see Figures 1 to 5 The inner sidewall of the inner slide groove 223 has a first guide protrusion 2231 extending along the outer slide groove 224. The first guide protrusion 2231 is located at the entrance 225, so that the positioning protrusion 252 slides into the outer slide groove 224 at the entrance 225. The rotating member 22 has a second guide protrusion 2241 on the outer sidewall of the outer slide groove 224, which extends along the inner slide groove 223. The second guide protrusion 2241 is located at the exit 226, so that the positioning protrusion 252 slides from the entrance 225 into the locking groove 227.

[0112] First guide protrusion 2231 is a protrusion located on the inner sidewall of inner chute 223 and extending along outer chute 224, located at entrance 225. The primary function of first guide protrusion 2231 is to guide positioning protrusion 252 from entrance 225 into outer chute 224. Through its specific shape and position, first guide protrusion 2231 alters the trajectory of positioning protrusion 252, enabling it to accurately enter the sliding track of outer chute 224, laying the foundation for subsequent sliding within the entire chute system.

[0113] The form of the first guide protrusion 2231 is not limited herein. For example, it can be in the shape of an arc-shaped transition protrusion. When the positioning protrusion 252 approaches the inlet 225, it can gradually change direction along the arc surface and enter the outer chute 224, thereby reducing collision or jamming caused by sudden changes in direction.

[0114] The height and width of the first guide protrusion 2231 need to be reasonably designed according to the size of the positioning protrusion 252 and the specifications of the outer slide groove 224, so as to ensure that the positioning protrusion 252 can be effectively guided into the outer slide groove 224 without hindering the normal sliding of the positioning protrusion 252 in the slide groove.

[0115] The second guide protrusion 2241 is located on the outer wall of the outer chute 224 of the rotating member 22 and extends along the inner chute 223. It is located at the exit 226. Its function is to guide the positioning protrusion 252 from the outer chute 224 into the retaining groove 227 when the positioning protrusion 252 enters the chute system from the entrance 225 and slides along the chute to the exit 226. This ensures that the positioning protrusion 252 can accurately engage with the retaining groove 227, effectively limiting the rotational position of the rotating member 22.

[0116] The second guide protrusion 2241 can be designed as a sloped surface at a predetermined angle at the exit 226. When the positioning protrusion 252 slides near the exit 226, the slope guides the positioning protrusion 252 toward the slot 227 and provides a buffer when it engages the slot 227, ensuring a smoother engagement process. The relative position of the second guide protrusion 2241 and the slot 227 is also crucial. The distance and angle between the two must be precisely matched to ensure that the positioning protrusion 252 can smoothly transition from the outer groove 224, through the second guide protrusion 2241, and into the slot 227.

[0117] The first guide protrusion 2231 and the second guide protrusion 2241 can be made of a material with a certain degree of elasticity and wear resistance, such as rubber or a nylon-fiber composite. The elastic material can act as a buffer when the positioning protrusion 252 contacts the guide protrusion, reducing wear and collision noise. The wear resistance ensures that the guide protrusion will not be damaged by frequent friction during long-term use, maintaining the stability of its guiding function.

[0118] In addition, some tiny grooves or raised textures can be set on the inner slide groove 223 and the wall of the inner slide groove 223 near the entrance 225 and the exit 226. These textures can increase the friction between the positioning protrusion 252 and the wall of the slide groove, and play a certain auxiliary fixing role when the positioning protrusion 252 enters or leaves the slide groove, preventing the positioning protrusion 252 from deviating from the predetermined sliding path due to accidental shaking or slight external force.

[0119] The presence of the first guide protrusion 2231 and the second guide protrusion 2241 significantly improves the accuracy of the positioning protrusion 252's movement at the entrance 225 and exit 226. During initial entry, the first guide protrusion 2231 ensures that the positioning protrusion 252 accurately enters the outer chute 224, preventing the positioning protrusion 252 from slipping into the incorrect position or failing to enter the chute due to structural complexity at the entrance 225. At the exit 226, the second guide protrusion 2241 allows the positioning protrusion 252 to precisely engage the retaining groove 227, accurately defining the rotational position of the rotating member 22. This ensures the stability and reliability of the rotating member 22 when it needs to be fixed, thereby ensuring that the winding and unwinding operations of the data cable 23 are controlled to the desired position and length. The special design of the guide protrusions, such as the arc and bevel, ensures smoother movement of the positioning protrusion 252 during entry and engagement with the retaining groove 227. It reduces the adverse phenomena such as jamming and collision caused by sudden changes in direction or forced insertion, not only reduces the resistance during operation, making the rotation and positioning operations of the rotating part 22 easier and smoother, but also reduces the wear between components, extends the service life of the entire positioning system, and provides users with a more comfortable and convenient use experience.

[0120] In some embodiments, see Figures 1 to 5 A first magnetic portion 2311 is provided on the free end of the first connecting section 231 , and a second magnetic portion 215 is provided on the main body 21 . The first magnetic portion 2311 and the second magnetic portion 215 are magnetically engaged with each other.

[0121] The first magnetic portion 2311 is a magnetic component arranged at the free end of the first connecting section 231. It can generate a magnetic field and interact with other magnetic components. In this design, it mainly produces magnetic attraction and cooperation with the second magnetic portion 215 on the main body 21, thereby realizing specific functions, such as fixing the position of the first connecting section 231 or assisting it to maintain stability in a specific state.

[0122] The second magnetic portion 215 is located on the main body 21 and is a magnetic component corresponding to the first magnetic portion 2311. Through the magnetic attraction with the first magnetic portion 2311, it can absorb, position or guide the first connecting section 231 in different scenarios, helping to maintain the stability and order of the data cable 23 structure of the entire mobile phone case 10.

[0123] In some embodiments, a third magnetic portion 2321 is provided on the free end of the second connecting section 232 , and a fourth magnetic portion 216 is provided on the main body 21 . The third magnetic portion 2321 and the fourth magnetic portion 216 are magnetically engaged with each other.

[0124] The third magnetic portion 2321 is a magnetic element installed at the free end of the second connecting section 232, similar to the first magnetic portion 2311. Its function is to form a magnetic relationship with the fourth magnetic portion 216 on the main body 21 to perform relevant position control or functional assistance on the second connecting section 232.

[0125] The fourth magnetic attraction portion 216 is provided on the main body 21 and is a magnetic part that matches the third magnetic attraction portion 2321. The magnetic attraction between the two can achieve functions such as regularizing the second connecting section 232 when the data cable 23 is stored, or guiding the extension direction of the data cable 23 during use.

[0126] The magnetic strength of each magnetic attraction part needs to be reasonably adjusted according to actual usage requirements. If the magnetism is too strong, it may be difficult to separate from the main body 21 even when adsorption is not required, affecting the normal use of the data line 23; if the magnetism is too weak, effective adsorption and positioning functions may not be achieved.

[0127] The shapes of the magnetic portions can be variously designed, such as circular, square, or elongated. These shapes can be determined based on the spatial layout of the free end of the first connecting segment 231 and the corresponding positions of the main body 21, as well as aesthetic requirements. Furthermore, to improve the stability and accuracy of magnetic attraction, positioning protrusions 252 or grooves can be provided on the surface of the magnetic portions to ensure more precise docking during magnetic engagement.

[0128] When the data cable 23 is not in use, the magnetic attraction of each magnetic attraction portion enables the first connecting section 231 and the second connecting section 232 to be attached to the corresponding position of the main body 21, preventing the data cable 23 from becoming tangled due to looseness. This makes the storage of the data cable 23 more neat and orderly, making it easier for the user to quickly find and unfold the data cable 23 the next time they use it, thereby improving usage efficiency. The provision of the magnetic attraction portion also makes the connection between the mobile phone case 10 and the data cable 23 more compact and natural, reducing the abruptness and unsightly appearance that may be caused by traditional mechanical connection methods (such as buckles and clips).

[0129] In some embodiments, see Figures 1 to 5 The first connecting section 231 is connected to the main body 21 , and the second connecting section 232 is wound around the circumferential outer side of the rotating member 22 . The length of the first connecting section 231 is greater than or equal to 60 mm and less than or equal to 70 mm.

[0130] The specific length of the first connecting section 231 is not limited here, for example, it can be 60mm, 61mm, 62mm, 63mm, 64mm, 65mm, 66mm, 67mm, 68mm, 69mm and 70mm, etc.

[0131] The length of the first connecting section 231 is limited to between 60mm and 70mm. This length range ensures that after connection with the main body 21, it is long enough to extend to the appropriate position for effective connection with components such as the charging port of a mobile phone, ensuring stable data and power transmission, while also being short enough to occupy too much space within the mobile phone case 10 and affect the overall compactness and aesthetics of the mobile phone case 10. Furthermore, this suitable length ensures that the first connecting section 231 maintains a good connection when subjected to external forces during daily use of the mobile phone, reducing problems such as loose connections and broken circuits caused by excessive or insufficient length.

[0132] In some embodiments, see Figures 1 to 5 The shell body 1 is recessed toward one side of the first accommodating cavity 11 to form a recessed area 12 , and the data cable box 2 is disposed in the recessed area 12 .

[0133] The recessed area 12 is formed by the case body 1 being recessed toward the first accommodating cavity 11. Its shape and size are determined by specific design requirements. Recessed area 12 is a relatively low-lying area intentionally created within the original structure of the case body 1. Its primary purpose is to accommodate specific components such as the data cable box 2, allowing these components to be rationally integrated within the phone case 10 without increasing the overall thickness of the case body 1 or occupying excessive space.

[0134] There are many ways to expand the way the shell body 1 is recessed toward one side of the first accommodating cavity 11 to form the recessed area 12. For example, the edge of the recessed area 12 can adopt an arc-shaped transition design, which not only makes the appearance more beautiful and smooth, but also when the user holds the mobile phone, there will be no obvious abrupt feeling when the finger touches the edge of the recessed area 12, thereby improving the comfort of holding the phone. At the same time, the depth of the recessed area 12 can be reasonably adjusted according to the size of the data cable box 2 and the operating space that needs to be reserved. If the data cable box 2 is relatively large and more complex data cable 23 operations need to be performed therein (such as frequent unwinding, winding, etc.), the depth of the recessed area 12 can be appropriately deepened to provide sufficient space.
