[0003] Wired charging technology transmits power by connecting a charging cable. Its advantages include high charging efficiency and support for simultaneous charging and use. However, it suffers from inconvenient cable management. While wireless charging technology eliminates the constraints of charging cables, it cannot enable mobile devices to be used while charging.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0036] Currently, the mainstream vehicle charging solutions on the market are mainly divided into two technical routes: wired charging and wireless charging. Wired charging technology transmits power through a charging cable. Its advantages include high charging efficiency and support for simultaneous charging and use of mobile devices. However, the wiring harness is relatively messy after charging, resulting in inconvenient wiring management. While wireless charging technology eliminates the constraints of charging cables, it cannot achieve the function of simultaneous charging and use of mobile devices. The embodiments of this application provide a charging device that enables simultaneous charging and use of mobile devices and facilitates wiring management.

[0037] Please refer to Figures 1-6 The charging device 10 provided in the embodiments of this application includes a mounting body 100 and a retractor 200 disposed inside the mounting body 100. A charging cable harness 210 is disposed inside the retractor 200. One end of the charging cable harness 210 is used to connect to the vehicle power supply, and the other end of the charging cable harness 210 is provided with a magnetic male connector 211. The magnetic male connector 211 is at least partially located outside the mounting body 100 so as to magnetically connect with the magnetic female connector 310 on the mobile terminal 300.

[0038] The retractor 200 is used to store the charging cable harness 210. One end of the charging cable harness 210 is used for electrical connection to the vehicle power supply. The charging cable harness 210 can be directly connected to the vehicle power supply, or connected to the vehicle power supply through other cables, or pulled out and connected to the vehicle's USB port. The other end of the charging cable harness 210 is provided with a magnetic male connector 211, and a magnetic female connector 310 is inserted into the charging port on the mobile terminal 300. The magnetic male connector 211 extends at least partially beyond the mounting body 100 to achieve a magnetic connection with the magnetic female connector 310 on the mobile terminal 300, so that the mobile terminal 300 can enter the charging state after the magnetic connection is completed. The mounting body 100 can be a storage box, and the mobile terminal 300 can be a mobile phone, tablet computer, etc.

[0039] When the user brings the magnetic female connector 310 on the mobile terminal 300 close to the magnetic male connector 211 and completes the magnetic connection, the magnetic force between the magnetic male connector 211 and the magnetic female connector 310 is greater than the coiling spring force inside the retractor 200. The user can then pull out the charging cable 210 to a certain length, enabling simultaneous charging and use. After charging is complete, the user only needs to disconnect the magnetic female connector 310 from the magnetic male connector 211 on the mobile terminal 300. The charging cable 210 will then be automatically retracted into the mounting body 100 by the retractor 200, thus avoiding the problem of exposed and messy cables.

[0040] After the user pulls out the charging cable harness 210 to a certain length, the retractor 200 can keep the charging cable harness 210 at any length to meet different user needs. When the connection between the magnetic male connector 211 and the magnetic female connector 310 is disconnected and the charging cable harness 210 is pulled out again, the retractor 200 can retract the charging cable harness 210 again.

[0041] While retaining the high efficiency and stability of wired charging, the charging device 10 improves user convenience and wiring harness management through a detachable connection structure between the magnetic male connector 211 and the magnetic female connector 310. This effectively solves the problems of messy wiring harnesses and inconvenient charging operation in existing vehicle charging devices 10, while retaining the high efficiency and simultaneous charging and use functions of wired charging.

[0042] In some embodiments, the mounting body 100 is provided with a placement slot 110 for placing the mobile terminal 300, and the magnetic male head 211 extends at least partially into the placement slot 110 and is used for magnetic connection with the magnetic female head 310 on the mobile terminal 300.

[0043] The placement slot 110 has a placement area that roughly matches the shape of the mobile terminal 300. The magnetic male connector 211 extends at least partially into the placement slot 110, so that when the mobile terminal 300 is placed in the placement area, the magnetic male connector 211 can align with the magnetic female connector 310 on the mobile terminal 300 and achieve magnetic connection. In this embodiment, the placement area in the placement slot 110 constitutes a guiding area for the magnetic connection action, so as to quickly achieve docking between the magnetic female connector 310 and the magnetic male connector 211.

[0044] When the user places the mobile terminal 300 into the placement area, the magnetic female connector 310 of the mobile terminal 300 moves closer to the magnetic male connector 211 under the limiting effect of the placement area, and then a stable magnetic connection is quickly achieved under the magnetic attraction of the two. This design eliminates the need for additional plugging and unplugging operations by the user; simply placing the mobile terminal 300 into the placement area quickly establishes an electrical connection, thus improving the convenience of charging. Furthermore, the placement area also helps to position the mobile terminal 300, preventing it from shifting due to vibration or inertia during vehicle operation, thereby ensuring the stability of the magnetic connection and the continuity of the charging process.

[0045] It should be noted that the friction between the mobile terminal 300 and the bottom wall of the placement slot 110 is less than the coiling spring force inside the retractor 200. When the mobile terminal 300 is placed in the placement area and the magnetic female head 310 is connected to the magnetic male head 211, the charging cable harness 210 is gradually retracted under the action of the retractor 200, thereby pulling the mobile terminal 300 a certain distance so that the charging cable harness 210 is hidden inside the mounting body 100.

[0046] When charging is not required, lift the mobile terminal 300 along the bottom wall of the vertical placement slot 110. The magnetic female connector 310 and the magnetic male connector 211 will separate due to shearing force, and the charging cable harness 210 will automatically retract.

[0047] Please refer to Figure 7 In some embodiments, a through hole 111 is provided on the side wall of the placement groove 110, and the magnetic male head 211 extends out of the mounting body 100 through the through hole 111.

[0048] The placement slot 110 is a rectangular slot, and a through hole 111 is formed on one of the side walls of the placement slot 110. The position of the through hole 111 matches the placement posture of the mobile terminal 300 so as to realize the quick connection between the magnetic male connector 211 and the magnetic female connector 310 when the mobile terminal 300 is placed in the placement area.

[0049] The through-hole 111 serves as the exit point for the charging cable harness 210 to interact with the outside world. It not only provides an extension path for the magnetic male connector 211 but also limits the movement trajectory of the charging cable harness 210. Specifically, when the mobile terminal 300 is placed in the placement area, the magnetic female connector 310 and the magnetic male connector 211 align near the through-hole 111 and establish a magnetic connection. At this time, the charging cable harness 210 can be pulled out from the retractor 200. The movement path of the charging cable harness 210 is guided and constrained by the through-hole 111, preventing cable harness deviation. After charging is complete, the user disconnects the magnetic female connector 310 from the magnetic male connector 211. Under the winding action of the retractor 200, the charging cable harness 210 retracts along its original path and returns to the mounting body 100 through the through-hole 111, thus achieving automatic storage of the charging cable harness 210.

[0050] In some embodiments, the cross-sectional area of ​​the through hole 111 is greater than or equal to the cross-sectional area of ​​the magnetic male connector 211.

[0051] To ensure that the magnetic male connector 211 can pass smoothly through the through hole 111 without causing assembly difficulties or movement obstruction due to dimensional interference, the cross-sectional area of ​​the through hole 111 must be greater than or equal to the cross-sectional area of ​​the magnetic male connector 211. Preferably, the cross-sectional area of ​​the through hole 111 is slightly larger than the cross-sectional area of ​​the magnetic male connector 211.

[0052] When the cross-sectional area of ​​the through hole 111 is greater than or equal to the cross-sectional area of ​​the magnetic male connector 211, the outer peripheral surface of the magnetic male connector 211 can maintain a basically interference-free fit with the edge of the through hole 111 during the process of extending or retracting from the through hole 111, thereby avoiding movement obstruction caused by movement offset. In addition, the through hole 111 only needs to meet the function of normal insertion of the magnetic male connector 211, so the through hole 111 itself occupies less space, thus reserving more usable space for the arrangement of other structural components in the vehicle.

[0053] Please refer to Figure 4 and Figure 8 In some embodiments, a wire harness conduit 400 is provided inside the mounting body 100, and the magnetic male connector 211 extends into the mounting body 100 from the first end of the wire harness conduit 400 and extends out of the mounting body 100 from the second end of the wire harness conduit 400.

[0054] The resistance experienced by the charging cable harness 210 within the cable harness conduit 400 should be less than the spring force inside the retractor 200. The cable harness conduit 400 serves as a channel for the charging cable harness 210 to extend from the retractor 200 to the outside of the mounting body 100. Its first end faces the cable outlet of the retractor 200, and its second end faces the outside of the mounting body 100. The magnetic male connector 211 extends into the cable harness conduit 400 from its first end, travels along the extension direction of the conduit 400, and finally extends out of the mounting body 100 from its second end. This design ensures that the charging cable harness 210 always moves along a predetermined path when pulled out for use, preventing interference or jamming with other internal structures of the mounting body 100 due to free swinging or excessive bending angles. This improves the smoothness of the cable harness movement and the overall reliability of the device operation.

[0055] When the mounting body 100 is provided with a placement groove 110 and the side wall of the placement groove 110 is provided with a through hole 111, the second end of the wire harness conduit 400 is directly opposite the through hole 111. The magnetic male head 211 can enter the wire harness conduit 400 from the first end of the wire harness conduit 400, and then extend into the placement groove 110 through the second end of the wire harness conduit 400 and the through hole 111 to magnetically connect with the magnetic female head 310 on the mobile terminal 300.

[0056] The shape of the wire harness conduit 400 can be adjusted according to the internal space of the mounting body 100. For example, the wire harness conduit 400 may include a first pipe section 410 and a second pipe section 420 at an angle, wherein the first pipe section 410 is arranged vertically and the second pipe section 420 is arranged obliquely upward. The first end of the wire harness conduit 400 is the end of the first pipe section 410 away from the second pipe section 420, and the second end of the wire harness conduit 400 is the end of the second pipe section 420 away from the first pipe section 410.

[0057] In some embodiments, the retractor 200 is provided with a connector 220, which is connected to the first end of the wire harness conduit 400, and the magnetic male connector 211 extends into the wire harness conduit 400 through the connector 220.

[0058] The connector 220 serves as a transitional connection between the retractor 200 and the cable harness conduit 400. One end of the connector communicates with the interior of the retractor 200, while the other end connects to the first end of the cable harness conduit 400, creating a continuous cable harness channel between the cable harness conduit 400 and the retractor 200. The magnetic male connector 211, as the end structure of the charging cable harness 210, extends through the connector 220 and enters the interior of the cable harness conduit 400. It then moves along the extension direction of the cable harness conduit 400 and finally extends out of the mounting body 100 from the second end of the cable harness conduit 400. This design ensures that the charging cable harness 210 remains within a controlled tubular channel during pull-out or retraction, preventing it from deviating from its intended path due to free bending or uneven force. This effectively avoids the charging cable harness 210 being exposed, tangled, or interfering with other structures inside the mounting body 100.

[0059] By setting a connecting pipe 220 on the retractor 200 and forming a docking structure with the wire harness conduit 400, the overall sealing and guiding continuity of the wire harness guiding system are further improved, achieving the effect of fully enclosed wiring of the charging wire harness 210 inside the device, and improving the overall operational reliability of the device.

[0060] Please refer to Figure 9 In some embodiments, one end of the connector 220 away from the retractor 200 and one end of the first end of the wire harness conduit 400 are provided with a stepped surface 430, and the other end abuts against the stepped surface 430.

[0061] Between the end of the connector 220 furthest from the retractor 200 and the first end of the cable harness conduit 400, one end has a stepped surface 430, and the other end abuts against this stepped surface 430. This design allows the connector 220 and the cable harness conduit 400 to achieve axial alignment during assembly through the limiting effect of the stepped surface 430, ensuring that they are coaxial or height-aligned when connected. The magnetic male connector 211 and its connected charging cable harness 210 need to enter the cable harness conduit 400 through the connector 220. If there is a large offset or misalignment between the connector 220 and the cable harness conduit 400, the charging cable harness 210 may get stuck, bent, or obstructed when passing through, affecting its smooth movement. The alignment effect of the stepped surface 430 effectively avoids the above problems, thus providing a more spacious and continuous routing space for the charging cable harness 210.

[0062] Optionally, the stepped surface 430 is provided at the first end of the wire harness conduit 400. The inner diameters of the wire harness conduits 400 connected to both sides of the stepped surface 430 are different. When the end of the connector 220 away from the retractor 200 abuts against the stepped surface 430, the outer wall of the connector 220 is restricted by the inner wall of the wire harness conduit 400 with a larger inner diameter connected to one side of the stepped surface 430, so that it is not easy to move radially relative to the wire harness conduit 400, thereby ensuring that the connector 220 and the wire harness conduit 400 are in a coaxial or height-aligned state.

[0063] By setting a stepped surface 430 between the connector 220 and the wire harness conduit 400 and achieving abutment fit, not only is the misalignment problem that may occur during the docking of the connector 220 and the wire harness conduit 400 solved, but the routing path of the charging wire harness 210 is also optimized, thereby achieving the effect of smooth passage and reliable connection of the charging wire harness 210.

[0064] In some embodiments, the retractor 200 is detachably connected to the mounting body 100, the mounting body 100 is provided with an access port 120 facing the retractor 200, and the mounting body 100 is detachably provided with a maintenance cover 130 at the access port 120.

[0065] The retractor 200 is detachably connected to the mounting body 100, allowing the retractor 200 to be separated from the mounting body 100 for maintenance after assembly. The mounting body 100 has a maintenance port 120 facing the retractor 200. This maintenance port 120 serves as an opening to the mounting position of the retractor 200, providing an operating channel for its disassembly and installation. Simultaneously, the mounting body 100 has a maintenance cover 130 at the maintenance port 120. This maintenance cover 130 is detachably fixed to the mounting body 100 and is used to close the maintenance port 120 when not in a maintenance state, maintaining the overall sealing and appearance integrity of the mounting body 100.

[0066] As a key component in the charging device 10 responsible for the storage and release of the wire harness, the retractor 200 may experience performance degradation or malfunction due to mechanical wear during operation. If a non-removable installation is used, a failure of the retractor 200 would require disassembling and repairing the entire charging device 10, which is not only complex but may also affect the normal use of other components. However, by detachably connecting the retractor 200 to the mounting body 100 and incorporating the inspection port 120 and maintenance cover 130, maintenance personnel can inspect or replace the retractor 200 without disassembling the overall structure of the charging device 10, simply by removing the maintenance cover 130. This significantly improves the maintainability of the retractor 200 and extends the service life of the charging device 10.

[0067] In some embodiments, one of the retractor 200 and the mounting body 100 is provided with a snap-fit ​​post 230 and the other is provided with a snap-fit ​​hole 140, and the snap-fit ​​post 230 engages with the snap-fit ​​hole 140.

[0068] After the snap-fit ​​post 230 is inserted into the snap-fit ​​hole 140, a snap-fit ​​engagement is formed, thereby stably fixing the retractor 200 inside the mounting body 100. Optionally, the retractor 200 is provided with the snap-fit ​​post 230, and the mounting body 100 is provided with the snap-fit ​​hole 140.

[0069] The snap-fit ​​between the snap-fit ​​post 230 and the snap-fit ​​hole 140 is a form of mechanical connection. Its principle is based on elastic deformation or interference fit. For example, when the snap-fit ​​post 230 and the snap-fit ​​hole 140 are fitted based on elastic deformation, the snap-fit ​​post 230 can achieve positioning through a brief deformation during the insertion of the snap-fit ​​post 230 into the snap-fit ​​hole 140, and return to its original shape after being inserted into place, thereby forming a stable connection.

[0070] The engagement method between the snap-fit ​​post 230 and the snap-fit ​​hole 140 not only avoids the additional assembly steps required by traditional screw connections, but also enables quick installation and disassembly without affecting the overall structural strength. When the retractor 200 needs maintenance or replacement, only a certain pulling force needs to be applied to disengage the snap-fit ​​post 230 from the snap-fit ​​hole 140, thus completing the separation operation between the retractor 200 and the mounting body 100. This design allows maintenance personnel to replace the retractor 200 without damaging the overall structure of the device, improving the maintainability of the retractor 200.

[0071] In some embodiments, a snap fastener 131 is provided on the maintenance cover 130, which is snapped onto the mounting body 100 so that the maintenance cover 130 closes the inspection port 120.

[0072] The buckle 131 serves as a connection structure between the maintenance cover 130 and the mounting body 100. One end of the buckle is fixed to the maintenance cover 130, while the other end extends and is snapped onto the mounting body 100, so that the maintenance cover 130 and the mounting body 100 form a stable snap-fit ​​engagement through the buckle 131.

[0073] Optionally, the mounting body 100 has a flange 150 at the access port 120. When the clips 131 on the maintenance cover 130 extend into the mounting body 100 through the access port 120, they engage with the flange 150. There can be multiple clips 131 arranged circumferentially along the maintenance cover 130. When there are multiple clips 131, the flange 150 is arranged in a circle around the access port 120, and all the clips 131 are engaged with the flange 150.

[0074] When the maintenance cover 130 is installed in place, the latch 131 engages with the flange 150 on the mounting body 100, thereby stably fixing the maintenance cover 130 to the inspection port 120 of the mounting body 100, effectively sealing the inspection port 120. When maintenance is required, only a certain external force needs to be applied to disengage the latch 131 from the flange 150, and the maintenance cover 130 can be removed from the inspection port 120, thus providing operating space for the disassembly or replacement of the retractor 200.

[0075] The snap-fit ​​structure 131 not only simplifies the assembly process of the maintenance cover 130 but also reduces the assembly difficulty associated with traditional screw connections. This snap-fit ​​structure relies on the elastic deformation of the material to achieve engagement and disengagement, allowing the maintenance cover 130 to be installed and removed without additional tools, thus improving the ease of use of the device. This design ensures that the maintenance cover 130 maintains a good fit with the mounting body 100 in non-maintenance states while allowing for quick opening during maintenance, balancing structural stability with operational flexibility.

[0076] In some embodiments, the mounting body 100 can be understood as a center console, armrest module, door armrest module, second / third row armrest module, etc., within the vehicle cabin.
