Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0041] See appendix Figure 1 - Appendix Figure 5 and attached Figure 11 A multi-purpose magnetic power bank includes a power bank body 1 and a base cover 2. The power bank body 1 is provided with a power supply unit 11, a magnetic charging unit 12, and a charging compartment 13. The power supply unit 11 is located inside the power bank body 1 and is used to supply / disconnect power to the magnetic charging unit 12 and the charging compartment 13. The magnetic charging unit 12 is located on the front side of the power bank body 1 and can be attached to the back of a mobile phone 3 for charging. The charging compartment 13 opens to the back side of the power bank body 1 and can hold a wireless earphone 4 for charging. The base cover 2 is provided with a connecting rod 21, which is rotatably connected to the side wall of the power bank body 1 and has rotational damping, so that the base cover 2 can open / close the charging compartment 13. After the base cover 2 opens the charging compartment 13, it can be used as a mobile phone stand in conjunction with the power bank body 1.

[0042] Specifically, under normal circumstances, the wireless earphones 4 are placed inside the charging case 13, and the cover 2 closes the opening of the charging case 13, so that the wireless earphones 4 are integrated into the power bank body 1, making it convenient to carry and use together. At the same time, the charging case 13 will also charge the wireless earphones 4 to ensure that the wireless earphones 4 have sufficient power.

[0043] When in use, place the phone 3 against the power bank body 1 so that the magnetic charging unit 12 can attract the phone 3 for charging; if you need to use earphones, rotate the cover 2 to open the charging case 13 and take out the wireless earphones 4 to wear; at the same time, after the cover 2 is opened, it stops under the action of rotational damping. At this time, the power bank body 1 can be placed vertically on the table. The power bank body 1, the cover 2 and the table form a triangular structure to form a phone stand, which makes it convenient to free the user's hands.

[0044] After use, place the wireless earbuds 4 back into the charging case 13, and then rotate the cover 2 to close the opening of the charging case 13.

[0045] In summary, this utility model designs a magnetic charging unit 12 and a charging compartment 13 on the power bank body 1 for charging the mobile phone 3 and wireless earphone 4 respectively, and designs a cover 2 for opening / closing the charging compartment 13. At the same time, the cover 2 works with the power bank body 1 to act as a mobile phone stand. Therefore, compared with the prior art, this solution can not only hold the wireless earphone 4, but also be used as a mobile phone stand, and can also charge the wireless earphone 4 and the mobile phone 3 at the same time. It integrates multiple functions, enriches the uses of the magnetic power bank, and improves portability and user experience.

[0046] It should be noted that this magnetic power bank can also charge electronic products with magnetic charging function, such as tablets and e-readers, and is not intended to be limited to mobile phones.

[0047] See appendix Figure 4 - Appendix Figure 5 Since there are various types of power supply units 11, most of which belong to the prior art, this utility model does not limit them. For ease of understanding, in this embodiment, the power supply unit 11 includes a circuit board 111, a storage battery 112, a control button 113, and a charging port 114. The circuit board 111 is electrically connected to the magnetic charging unit 12, the charging compartment 13, the storage battery 112, the control button 113, and the charging port 114. The control button 113 and the charging port 114 are both located on the outer wall of the power bank body 1. The control button 113 is used to control the operating status of the circuit board 111, and the charging port 114 can be connected to the data cable P to charge the storage battery 112 using external power or to power external electronic products using the storage battery 112.

[0048] Specifically, during use, pressing the control button 113 drives the circuit board 111 to release the electrical energy of the battery 112 to power the magnetic charging unit 12 and the charging case 13, thereby charging the mobile phone 3 and the wireless earphone 4. If the control button 113 is pressed again, the circuit board 111 can be driven to cut off the circuit channel between the battery 112 and the magnetic charging unit 12 and the charging case 13, thereby cutting off the power. Of course, in the actual production process, the function of the control button 113 is preset by the manufacturer, so the control button 113 may also have other functions. Since the relevant technology is relatively conventional, it will not be further described in this embodiment.

[0049] On the other hand, as attached Figure 12 As shown, the battery 112 can also supply power to the charging port 114. When using electronic products such as mobile phones 3 and tablets that do not have magnetic charging function, users can connect the charging port 114 and the electronic product through the data cable P so that the battery 112 can directly charge the electronic product through the charging port 114 and the data cable P. In addition, when the battery 112 is depleted, the battery 112 can be charged by connecting the charging port 114 and the external charger 6 through the data cable P.

[0050] See appendix Figure 4 - Appendix Figure 6 The power supply unit 11 also includes multiple LED indicator lights 115 electrically connected to the circuit board 111. These LED indicator lights 115 can have different functions, which can be preset by the manufacturer according to requirements. For example, when the data cable P is connected to the charging port 114 and the electronic device, it is in wired charging mode, and the LED indicator lights 115 can be preset to emit green light; when the mobile phone 3 is being charged by the magnetic charging bank body 1, it is in wireless charging mode, and the LED indicator lights 115 can be preset to emit alternating green and red light; when the data cable P is connected to the charging port 114 and the charger 6, it is in charging mode for the battery 112, and the LED indicator lights 115 can be preset to emit flashing red light. In addition, the remaining LED indicator lights 115 can also be used to display the battery level of the battery 112. Since the relevant technology is relatively common in the power bank field, its specific circuit structure will not be described in detail in this utility model.

[0051] See appendix Figure 4 - Appendix Figure 5 The magnetic charging unit 12 includes a magnetic ring 121 and a power output coil 122 electrically connected to the circuit board 111. The magnetic ring 121 and the power output coil 122 are coaxially arranged, and both the magnetic ring 121 and the power output coil 122 are enclosed within the front shell plate 14 of the power bank body 1.

[0052] Specifically, when the back of the mobile phone 3 is attached to the front shell 14 of the power bank body 1, the magnetic ring 121 attracts the magnetic ring (not shown in the figure) inside the mobile phone 3 to fix the mobile phone 3 to the power bank body 1. The power output coil 122 corresponds to the power receiving coil (not shown in the figure) inside the mobile phone 3. The circuit board 111 provides current to the power output coil 122, and the power output coil 122 transmits the electrical signal to the power receiving coil inside the mobile phone 3 to charge the mobile phone 3.

[0053] Among them, as attached Figure 11 As shown, since both the magnetic ring 121 and the magnetic coil inside the phone 3 are circular, when this magnetic power bank is used as a phone stand, the user can adjust the phone 3 to a horizontal or vertical position, or even rotate the phone 3 at any angle to meet their needs, further improving the user experience.

[0054] It should be noted that since the wireless charging technology mentioned above is existing technology in this field, its specific principle will not be described in detail here. On the other hand, the shell plate 14 can be fixed to the power bank body 1 by screws or glue, or by directly using a snap-fit ​​method. Since there are various installation methods, this utility model does not limit this.

[0055] See appendix Figure 3 - Appendix Figure 6 The charging case 13 is equipped with a first magnet 131 and an electrical contact 132 that is electrically connected to the circuit board 111. The wireless earphone 4 is equipped with a first magnetic block 41 and a conductive sheet 42 that is electrically connected to the battery inside the wireless earphone 4.

[0056] Specifically, when the wireless earphone 4 is placed in the charging case 13, the first magnet 131 attracts the first magnetic block 41 to fix the wireless earphone 4, and the power contact 132 contacts the conductive sheet 42 for charging. This design makes it less likely for the wireless earphone 4 to fall out of the charging case 13 and be lost when the user uses this magnetic power bank as a mobile phone stand.

[0057] It should be noted that the first magnetic block 41 and conductive sheet 42 built into the wireless earphone 4 are conventional designs, and the technology of achieving circuit flow through the cooperation of the energized contact 132 and the conductive sheet 42 is also relatively existing. Therefore, the specific fixing method of the first magnetic block 41 and the conductive sheet 42, as well as the specific circuit structure between the energized contact 132 and the conductive sheet 42, will not be described in detail in this utility model.

[0058] See appendix Figure 3 - Appendix Figure 6 The charging case 13 is also equipped with an ultraviolet lamp 133, which is electrically connected to the circuit board 111 and illuminates the earbud part of the wireless earphone 4.

[0059] Specifically, when the wireless earphone 4 is placed in the charging case 13, the earbud part of the wireless earphone 4 is aligned with the ultraviolet lamp bead 133. The battery 112 supplies power to the ultraviolet lamp bead 133 through the circuit board 111. The light emitted by the ultraviolet lamp bead 133 can disinfect and sterilize the earbud part of the wireless earphone 4 to ensure the cleanliness of the earbud part of the wireless earphone 4.

[0060] See appendix Figure 2 and attached Figure 8 - Appendix Figure 10 The inner side of the seat cover 2 is provided with a pad 22. When the seat cover 2 closes the charging case 13, the pad 22 is in contact with the main body of the wireless earphone 4. This design can prevent the seat cover 2 from rigidly colliding with the wireless earphone 4 and prevent the wireless earphone 4 from being damaged.

[0061] See appendix Figure 2 and attached Figure 8 - Appendix Figure 10 The seat cover 2 has a buffer block 23 on the inside. During the process of closing the charging compartment 13, the buffer block 23 abuts against the top wall of the charging compartment 13 before the seat cover 2. This design can prevent the seat cover 2 from being damaged by rigid collision with the charging compartment 13. At the same time, the buffer block 23 can provide tactile feedback when it contacts the charging compartment 13, which improves the user experience.

[0062] See appendix Figure 5 - Appendix Figure 8 The charging case 13 is also provided with a second magnet 134 on its side wall and a second magnet 24 on the seat cover 2. When the seat cover 2 closes the charging case 13, the second magnet 134 attracts the second magnet 24. This design can lock the seat cover 2 and prevent the seat cover 2 from easily opening the charging case 13 when it is not affected by external force, which would cause the wireless earphones 4 to fall out. At the same time, the second magnet 134 can also provide feedback when it attracts the second magnet 24, which further improves the user experience.

[0063] See appendix Figure 3 - Appendix Figure 10 The power bank body 1 has a rotating hole 15 on its side wall, and a rotating post 25 is provided on the end of the connecting rod 21 away from the seat cover 2. The rotating post 25 is rotatably connected to the rotating hole 15 and is interference-fitted.

[0064] Specifically, since the rotating column 25 and the rotating hole 15 are interference-fitted, there is a certain friction between them, so that there is rotational damping between the connecting rod 21 and the power bank body 1. When the force applied by the user to the seat cover 2 is greater than the friction between the rotating column 25 and the rotating hole 15, the connecting rod 21 can be driven to rotate. When the user stops applying pressure, the connecting rod 21 stops, so that the bracket formed by the power bank body 1 and the seat cover 2 can stably support the mobile phone 3.

[0065] It should be noted that, in addition to the above structure, a damping component (not shown in the figure) can be provided at the rotational connection between the connecting rod 21 and the power bank body 1 to provide rotational damping, or other damping structures can be used. Since there are many related structures, this utility model does not limit them.

[0066] See appendix Figure 6 - Appendix Figure 10 The rotating column 25 is composed of a first abutment 251 and a second abutment 252 with a forked design. The first abutment 251 and the second abutment 252 extend into the rotating hole 15 simultaneously and are rotatably connected to the rotating hole 15. The first abutment 251 and the second abutment 252 are interference-fitted with the rotating hole 15, thereby providing rotational damping between the connecting rod 21 and the power bank body 1. Pressing the first abutment 251 and the second abutment 252 can drive them to deform and move closer to each other.

[0067] Specifically, when it is necessary to install the connecting rod 21 onto the power bank body 1, pressing the first abutment 251 and the second abutment 252 causes them to move closer together, so that the outer diameter of the rotating post 25 is smaller than the inner diameter of the rotating hole 15, and the rotating post 25 can be easily inserted into the rotating hole 15 to complete the installation of the connecting rod 21; therefore, the bifurcated structure of the rotating post 25 improves the ease of installation of the connecting rod 21.

[0068] See appendix Figure 6 - Appendix Figure 10 In actual use, long-term rotation of the seat cover 2 can easily cause the connection between the connecting rod 21 and the power bank body 1 to loosen, resulting in the seat cover 2 being unable to stably stop and support the mobile phone 3. To solve this problem, this utility model also includes an adjusting bolt 5. A cavity 250 is formed between the first abutment block 251 and the second abutment block 252, and the cavity 250 gradually narrows towards the connecting rod 21. The adjusting bolt 5 is threadedly connected to the connecting rod 21, and the first end of the adjusting bolt 5 is provided with a tool groove 51. The end of the adjusting bolt 5 is placed in the cavity 250 and is provided with a pressing block 52 that synchronously abuts against the first abutment block 251 and the second abutment block 252.

[0069] Specifically, when a tool such as a screwdriver (not shown in the illustration) is inserted into the tool slot 51 and the adjusting bolt 5 is rotated in the forward direction, the pressure block 52 is driven to move outward to squeeze the first abutment block 251 and the second abutment block 252. At this time, the outer diameter of the rotating column 25 gradually expands and opens the surrounding cavity 250, thereby increasing the rotational damping between the connecting rod 21 and the power bank body 1. If the rotational damping is too high, a tool such as a screwdriver (not shown in the illustration) is inserted into the tool slot 51 and the adjusting bolt 5 is rotated in the reverse direction to drive the pressure block 52 to move inward to loosen the first abutment block 251 and the second abutment block 252. At this time, the first abutment block 251 and the second abutment block 252 recover their deformation and reduce the outer diameter of the rotating column 25, thereby reducing the rotational damping between the connecting rod 21 and the power bank body 1. Users can rotate the adjusting bolt 5 according to the actual situation to meet their usage needs, further improving the user experience and extending the product's service life.

[0070] See appendix Figure 6 - Appendix Figure 8 A rubber ring 16 is coaxially installed inside the rotating hole 15. The rubber ring 16 is fitted and abuts against the first abutment block 251 and the second abutment block 252, and the rubber ring 16 also abuts against the side wall of the connecting rod 21. This design can increase the sealing of the rotating hole 15, prevent external water and dust from entering the interior of the power bank body 1, increase the wear resistance of the rotating hole 15, and effectively prevent damage to the rotating post 25.

[0071] See appendix Figure 2 Appendix Figure 4 and attached Figure 9 Considering that users may have specific requirements for the display angle of their phone 3 when using this magnetic power bank as a phone stand, and to facilitate users in quickly adjusting the swing angle of the cover 2 each time they use it, in this utility model, the end of the connecting rod 21 away from the cover 2 is also provided with a semi-circular scale 21k, and the power bank body 1 is provided with an indicator 1k, which can correspond to each part of the scale 21k as the connecting rod 21 rotates.

[0072] Specifically, after adjusting the swing angle of the seat cover 2 to meet the user's needs for the first time, the user can remember the current scale 21k position corresponding to the indicator 1k. When using it next time, the user can directly rotate the connecting rod 21 to quickly realign the indicator 1k with the scale 21k position to meet the user's needs. Therefore, the combined use of the indicator 1k and the scale 21k further improves the ease of use.

[0073] See appendix Figure 1 - Appendix Figure 12Two connecting rods 21 are provided and distributed on the left and right sides of the seat cover 2. The two connecting rods 21 are rotatably connected to the left and right side walls of the power bank body 1 and have rotational damping. This design can increase the connection points between the seat cover 2 and the power bank body 1, thereby ensuring that the seat cover 2 can more fully support the power bank body 1 and improve the overall structural stability.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
