DETAILED DESCRIPTION

[0024] Next, combine Figures 1-6 A specific embodiment of the present invention is described in detail.

[0025] refer to Figure 2 and Figure 5 , a power bank that prevents the charging line from being detached, comprising an installation box 1, a power bank 10 is provided on the installation box 1, a controlled reeling charging line 11 is connected to the power bank 10, a port of the charging line 11 is detachably connected to a plug 12, the plug 12 is replaceable to adapt to the charging port of different models, a magnetic plate 18 is detachably connected to the plug 12, a ring array magnet group is provided on the magnetic plate 18, and a directional adsorption force is formed with the permanent magnet of the back shell of the mobile phone, a positioning plate 19 is detachably installed on the magnetic plate 18, and the positioning plate 19 is fitted with the magnetic plate 18, the mobile phone The magnet group of the magnetic plate 18 of the machine is adsorbed and fits tightly with the alignment plate 19. The alignment plate 19 serves as a reference carrier for positioning the mobile phone, ensuring that the mobile phone charging port and the plug 12 are on the same axis. This device achieves the mobile phone charging effect through the cooperation of the power bank 10, the charging cable 11 and the plug 12. The strong magnetic attraction of the magnetic plate 18 and the alignment plate 19 on the mobile phone can ensure that the mobile phone is suspended on the plug 12 of the charging cable 11, avoiding the charging cable 11 from being separated from the mobile phone charging port when the mobile phone falls. The controlled winding action of the charging cable 11 achieves the traction effect on the mobile phone, helping the user to find it back.

[0026] refer to Figure 2 In the above description, the retrieval of the mobile phone after it falls depends on the winding action of the charging cable 11. Therefore, the present device realizes the winding of the charging cable 11 through a winding assembly. The winding assembly includes a docking piece 7 connected to the axis at the bottom of the installation box 1. The end of the docking piece 7 is clamped with an alignment sleeve 5. The alignment sleeve 5 is equipped with an upper gear plate 4 and a lower gear plate 9. There is an axial gap between the upper gear plate 4 and the lower gear plate 9 to form an annular wire groove. The charging cable 11 is spirally wound in the wire groove. The charging cable 11 is pulled by an external force, and the friction coupling between the charging cable 11 and the upper gear plate 4 and the lower gear plate 9 drives the upper gear plate 4, the lower gear plate 9 and the alignment sleeve 5 to rotate synchronously.

[0027] In order to realize the automatic winding function of the charging cable 11, a flat spiral spring is used as an energy storage element. The specific working mechanism is as follows: a spring 6 is provided at the bottom of the lower gear disc 9, the inner end of the spring 6 is fixed to the axis core of the lower gear disc 9, and the outer end is fixed to the inner wall of the mounting box 1. When the charging cable 11 is stretched, the upper gear disc 4, the lower gear disc 9 and the alignment sleeve 5 rotate synchronously, driving the spring 6 to wind tightly and store energy. At this time, the spring 6 is in a torque accumulation state. After the external force is removed, the elastic restoring force of the spring 6 drives the lower gear disc 9 to rotate in the opposite direction, and the upper gear disc 4 and the alignment sleeve 5 are linked to reverse, thereby realizing the automatic winding effect of the charging cable 11.

[0028] refer to Figure 3 A latching member 16 is slidably connected to the inner wall of the mounting box 1. The latching member 16 cooperates with the gear teeth of the upper gear plate 4. The latching member 16 and the upper gear plate 4 constitute a ratchet-type one-way locking structure. Its core function is to allow the upper gear plate 4 to rotate freely in the forward direction (i.e., the stretching direction of the charging cable 11) while inhibiting the upper gear plate 4 from rotating in the reverse direction (i.e., the winding direction of the charging cable 11), thereby realizing the controllable retraction and extension of the charging cable 11 under specific working conditions.

[0029] Pulling the charging cable 11 drives the upper gear plate 4, the lower gear plate 9 and the alignment sleeve 5 to rotate synchronously, and the spring 6 stores energy. After the charging cable 11 is extended to the target length, the back of the mobile phone fits with the alignment plate 19 due to the presence of the magnetic plate 18, ensuring that the mobile phone and the alignment plate 19 are firmly connected. The plug 12 is precisely aligned with the charging port of the mobile phone with the help of magnetism.

[0030] Based on the presence of the locking member 16, the upper gear disk 4 is immediately locked after the charging cable 11 is stretched, maintaining the constant length of the charging cable 11 to prevent accidental rewinding. After the mobile phone accidentally falls, the strong magnetism of the magnetic plate 18 can ensure that the mobile phone is hung on the plug 12 of the charging cable 11. By canceling the restriction of the locking member 16 on the upper gear disk 4, the elastic restoring force of the spring 6 drives the lower gear disk 9 to reverse, and the upper gear disk 4 and the positioning sleeve 5 are linked to reverse synchronously, thereby realizing automatic rewinding of the charging cable 11 and pulling the suspended mobile phone back to the user's reach. Through the coordinated design of mechanical transmission, magnetic positioning and automatic rewinding, the stable adsorption and anti-fall protection of the mobile phone during charging are realized, and when the mobile phone accidentally falls, the automatic rewinding function of the charging cable 11 is triggered by the locking member 16 to assist the user in retrieving the mobile phone.

[0031] refer to Figure 3 and Figure 4 The automatic winding action of the charging cable 11 depends on the disengagement of the positioning member 16 and the upper gear plate 4. Therefore, the present device adjusts the state of the positioning member 16 by a tripping assembly. The side wall of the installation box 1 is connected with a rotating member 13 of the operation input end. The rotating member 13 passes through the installation box 1 and is compressed with a torsion spring 14 between the installation box 1. The torsion spring 14 provides a reset torque. The installation box 1 is slidably connected with a sliding member 15. The sliding member 15 is fixedly connected to the positioning member 16. The action of the positioning member 16 depends on the action of the sliding member 15. One end of the sliding member 15 is connected to the rotating member 13. A movable groove is opened on the installation box 1. The sliding member 15 moves in the movable groove. The rotating member 13, the sliding member 15 and the positioning member 16 form a linkage whole.

[0032] The rotating member 13 is manually rotated, the sliding member 15 is controlled to move outward, and the locking member 16 is linked to move radially outward. The locking member 16 removes the restriction on the upper gear plate 4. Under the action of the spring 6, the lower gear plate 9 is reversed, and the upper gear plate 4 and the alignment sleeve 5 are linked to reverse synchronously, thereby realizing automatic winding of the charging cable 11.

[0033] After the user retrieves the phone, he releases the rotating part 13. Based on the existence of the torsion spring 14, the sliding part 15 moves inward and resets, and the linked locking part 16 moves radially inward and resets. The locking part 16 restricts the upper gear plate 4 again, and the relevant parts return to their initial state, which is convenient for subsequent recycling.

[0034] refer to Figure 2 A bolt 8 is threadedly connected to the docking piece 7, and the end of the bolt 8 is threadedly connected to the alignment sleeve 5, in order to achieve a stable connection between the docking piece 7 and the alignment sleeve 5 through the bolt 8, while facilitating the installation of the docking piece 7 and the alignment sleeve 5 in the installation box 1.

[0035] refer to Figure 2The alignment sleeve 5 is clamped with a bearing 3, the inner ring of the bearing 3 is clamped with the alignment sleeve 5, and the outer ring is fixed to the side wall of the mounting box 1, so as to make the rotation of the upper gear plate 4, the lower gear plate 9 and the alignment sleeve 5 smoother and reduce the energy loss when the mainspring 6 stores energy.

[0036] refer to Figure 1 In order to improve the environmental adaptability of the power bank 10, this device is protected by a protective shell 2 to effectively isolate the internal components from the influence of dust and external impact. The protective shell 2 is detachably connected to the installation box 1, and the power bank 10 is individually positioned and snapped into the inner cavity of the installation box 1, aiming to provide an independent protection space for the power bank 10 to ensure reliable operation in complex environments.

[0037] In order to store electricity for the power bank 10, a dedicated charging slot is provided on the side wall of the protective shell 2 to achieve safe access and reliable connection of the external power supply.

[0038] refer to Figure 5 In order to improve the adaptability of the device, an adapter 111 is provided at the port of the charging cable 11, and a plug 12 is detachably connected to the adapter 111, so that the charging port of different mobile phones can be adapted by replacing the plug 12.

[0039] refer to Figure 6 18 , so that the charging port of mobile phones of different thicknesses can be adjusted.

[0040] refer to Figure 6 The alignment plate 19 and the magnetic plate 18 of this device adopt a modular quick-release structure design, which is convenient for timely replacement of the alignment plate 19. The alignment plate 19 is equipped with a movable buckle 20, and the magnetic plate 18 is provided with a groove. The movable buckle 20 cooperates with the groove to achieve a stable connection between the alignment plate 19 and the magnetic plate 18. During assembly, the movable buckle 20 is manually rotated so that the edge of the movable buckle 20 contacts the groove. After the movable buckle 20 is fully in place, it rebounds and forms a mechanical interlock with the groove. During disassembly, the movable buckle 20 is rotated to release the interlock with the groove to complete the disassembly.

[0041] refer to Figure 5 The protective shell 2 is provided with a placement box 21, and a plurality of storage units are provided in the placement box 21. Each storage unit is provided with an alignment plate 19 to be replaced. The alignment plate 19 to be replaced is matched with an active buckle 20, which is intended to achieve orderly storage and quick access to the alignment plate 19. The placement box 21 is rotatably connected to a box cover 22. The box cover 22 and the placement box 21 together constitute an openable box body. Open the box cover 22, take out the alignment plate 19 to be replaced, and replace it.

[0042] refer to Figure 1 In order to ensure the thermal safety of the power bank 10 during continuous charging and discharging, this device dissipates heat through the following settings: the installation box 1 is connected to the inner cavity of the protective shell 2, a heat dissipation fan 24 is installed on the installation box 1, and an air vent is opened on the top of the protective shell 2. The heat generated during the continuous use of the power bank 10 can be effectively discharged through the heat dissipation fan 24 and the air vent.

[0043] refer to Figure 1 According to the background technology, this device is adapted to the use requirements in a vehicle environment. Therefore, the following method is adopted to ensure the stability and safety of the device during vehicle driving. A suction cup 23 is provided at the bottom of the installation box 1, which is manually pressed to form a vacuum adsorption on the stable platform. This suction cup 23 is suitable for interior materials such as glass and leather, thereby achieving the stability of the device in a vehicle environment.

[0044] In summary, this device uses the magnetic plate 18 and the alignment plate 19 to make the mobile phone fit tightly against the alignment plate 19. The alignment plate 19 serves as a reference carrier for positioning the mobile phone, ensuring that the mobile phone charging port and the plug 12 are on the same axis. The strong magnetism of the magnetic plate 18 can ensure that the mobile phone is suspended on the plug 12 of the charging cable 11, avoiding the mobile phone from being separated from the charging cable 11 when it falls; through the cooperation of the winding component and the release component, when the mobile phone accidentally falls during charging, the automatic winding function of the charging cable 11 is triggered to assist the user in retrieving the mobile phone; through the movable buckle 20, the alignment plate 19 and the magnetic plate 18 can achieve a quick release effect, which is convenient for the replacement of the alignment plate 19, and through the placement box 21, the alignment plate 19 can be orderly stored and quickly taken out, which is convenient for the continuous use of this device.
