Description

Technical Field

[0001] This utility model relates to the field of power bank technology, specifically to a split-type multi-functional magnetic wireless power bank. Background Technology

[0002] With the widespread use of electronic devices, people are becoming increasingly reliant on power banks in their daily lives. In practical scenarios, it's common for one person to carry multiple electronic devices, or for multiple people to simultaneously charge their respective devices. However, traditional all-in-one power banks present several inconveniences when powering multiple devices. Firstly, multiple devices need to be connected to the power bank via different charging cables, which often become tangled, making storage difficult and prone to pulling during use, affecting charging stability and potentially damaging the ports. Secondly, coordinating the charging order when multiple people share a single power bank can be frustrating and reduce the user experience.

[0003] To address the aforementioned issues, existing technologies have introduced power banks that can separately power multiple devices, such as partially detachable power banks (as shown in patent CN 219999065 U). By setting up a first charging element and a second charging element, multiple devices do not need to share the same power bank, reducing the inconvenience caused by excessive wiring. This detachable design, to some extent, meets the charging needs of multiple users in various scenarios, improving the flexibility of power bank usage.

[0004] However, these types of power banks still have some structural and functional shortcomings. For example, when electronic devices such as mobile phones do not have wireless charging capabilities, they can only be charged via wired connection, requiring an additional charging cable. In outdoor scenarios, if a compatible cable is not carried, electronic devices cannot be charged, greatly limiting the convenience of using the power bank. Furthermore, the primary charging unit in this type of structure is bulky, and even after separation, its size in use cannot be reduced.

[0005] The aforementioned shortcomings deserve improvement. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies, this utility model provides a split-type multi-functional magnetic wireless charging bank.

[0007] The technical solution of this utility model is as follows:

[0008] A split-type multi-functional magnetic wireless charging bank, characterized in that it includes:

[0009] A first charging and discharging module, comprising a first charging and discharging interface, a first USB interface, and at least one set of first magnetic wireless charging and discharging components, wherein the first charging and discharging module is connected to an electronic device or an external power source through the first charging and discharging interface and / or the first USB interface.

[0010] The second charging and discharging module includes a second battery and a second charging and discharging interface. The second charging and discharging module is connected to an electronic device or an external power source through the second charging and discharging interface.

[0011] The second charging and discharging module has a separate position and a connected position relative to the first charging and discharging module. When the second charging and discharging module is in the connected position relative to the first charging and discharging module, the first charging and discharging interface and the second charging and discharging interface are electrically connected, so that an external power source supplies power to the second battery through the first charging and discharging interface and the second charging and discharging interface, or the second battery supplies power to electronic devices through the second charging and discharging interface and the first charging and discharging interface.

[0012] According to the present invention based on the above scheme, the first charging and discharging module is further provided with a first storage battery.

[0013] According to the above-described scheme of this utility model, the second charging and discharging module is further provided with one or both of a second magnetic wireless charging and discharging component and a second USB interface.

[0014] According to the present invention based on the above scheme, one of the first charging / discharging interface and the second charging / discharging interface is a USB male connector, and the other of the first charging / discharging interface and the second charging / discharging interface is a USB female connector.

[0015] According to the above-described scheme of this utility model, the first charging / discharging interface and the second charging / discharging interface are charging / discharging contacts.

[0016] Furthermore, the charging and discharging contacts are magnetic charging and discharging contacts.

[0017] According to the present invention based on the above scheme, the first charging / discharging module or the second charging / discharging module is provided with a bracket, and the bracket has a storage position and a support position relative to the first charging / discharging module or the second charging / discharging module.

[0018] Furthermore, the bracket is rotatably connected to the first charging and discharging module. When the second charging and discharging module is in the connected position relative to the first charging and discharging module and the bracket is in the storage position, the bracket surrounds the periphery of the second charging and discharging module.

[0019] According to the present invention based on the above scheme, the first charging and discharging module is provided with an additional charging and discharging module, which can extend or be retracted relative to the first charging and discharging module. Both the first charging and discharging module and the additional charging and discharging module are provided with at least one set of the first magnetic wireless charging and discharging components.

[0020] Furthermore, the first charging and discharging module is provided with a storage slot, and the additional charging and discharging module is located in the storage slot and can slide along the storage slot.

[0021] The advantages of this utility model based on the above solution are as follows:

[0022] This invention utilizes a first charging / discharging module and a second charging / discharging module that can be used separately from each other, allowing for simultaneous charging of multiple electronic devices and increasing user convenience. Furthermore, the first charging / discharging module can employ both wireless and wired charging / discharging methods, while the second charging / discharging module can directly power electronic devices via a second charging / discharging interface, eliminating the need for charging cables. This avoids cable tangling and interface damage, improving charging convenience and stability, and providing greater flexibility in choosing charging methods.

[0023] In this invention, the first and second charging / discharging modules can be used independently. Essentially, the first module can be used as a magnetic wireless charger, and the second module as a plug-in power bank. They are connected only through the first and second charging / discharging interfaces. They can be directly connected and stored, or they can be separated. Compared to the bulky structure of traditional detachable power banks, this invention is smaller, making it easier to carry and use. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] like Figures 1 to 5 As shown, in order to increase the convenience of power banks when charging multiple electronic devices and reduce the size of power banks when used separately, this utility model provides a split-type multi-functional magnetic wireless power bank. It can charge multiple electronic devices simultaneously through different charging and discharging modules, which is convenient and fast. Moreover, the different charging and discharging modules are separate from each other and each is small in size, making it convenient for users to use.

[0033] Example 1

[0034] This split-type multi-functional magnetic wireless power bank includes a first charging / discharging module 10 and a second charging / discharging module 20. The second charging / discharging module 20 has a detachable position and a connected position relative to the first charging / discharging module 10, and the two can be used independently when separated. Most fundamentally, the first charging / discharging module 10 can be used alone as a magnetic wireless charger (i.e., it can wirelessly charge mobile phones and other electronic devices when connected to an external power source or connected to the second charging / discharging module), and can also be used as a magnetic wireless power bank when it has a built-in battery. The second charging / discharging module 20 can be used alone as a plug-in power bank, and can also be used as a magnetic wireless power bank when it has a built-in magnetic coil.

[0035] The first charging and discharging module 10 includes a first charging and discharging interface 12, a first USB interface 13, and at least one set of first magnetic wireless charging and discharging components. The first charging and discharging module 10 is connected to electronic devices such as mobile phones and power banks through the first charging and discharging interface 12 and / or the first USB interface 13 to supply power to them. The first charging and discharging module 10 can also be connected to an external power source (mains power, other power banks, etc.) through the first charging and discharging interface 12 and / or the first USB interface 13 to obtain power from the external power source. Based on this, the first charging and discharging module 10 can at least be used as a magnetic wireless charger.

[0036] The second charging / discharging module 20 includes a second battery and a second charging / discharging interface 21. The second charging / discharging module 20 is connected to electronic devices such as mobile phones and power banks through the second charging / discharging interface 21 to supply power to them. The second charging / discharging module 20 can also be connected to an external power source through the second charging / discharging interface 21 to obtain power from the external power source. Based on this, the second charging / discharging module 20 can at least be used as a power bank.

[0037] In this invention, the first charging / discharging module 10 includes a first charging / discharging body, and the second charging / discharging module 20 includes a second charging / discharging body. When the first charging / discharging body and the second charging / discharging body are mechanically connected, they are also electrically connected. At this time, the entire split-type multi-functional magnetic wireless power bank can also be used as a complete magnetic wireless power bank. That is, when the second charging / discharging module 20 is in the connected position relative to the first charging / discharging module 10, the first charging / discharging interface 12 and the second charging / discharging interface 21 are electrically connected, so that an external power source supplies power to the second battery through the first charging / discharging interface 12 and the second charging / discharging interface 21, or the second battery supplies power to electronic devices through the second charging / discharging interface 21 and the first charging / discharging interface 12.

[0038] In this embodiment, the first charging / discharging module 10 and the second charging / discharging module 20 of the split-type multi-functional magnetic wireless power bank can be separated and used individually to charge electronic devices, or they can be combined together to charge electronic devices, thereby increasing user convenience. Simultaneously, the second charging / discharging module 20 can also directly power electronic devices via the second charging / discharging interface 21 through a plug-in connection, ensuring that electronic devices without wireless charging capabilities can be used. Furthermore, in this embodiment, the first and second charging / discharging modules are compact after separation, making them convenient for users.

[0039] In one implementation, one of the first and second charging / discharging interfaces is a male USB connector, and the other is a female USB connector. In this embodiment, the first charging / discharging interface 12 is a female USB connector, and the second charging / discharging interface 21 is a male USB connector. In use, mobile phones and other electronic devices can be directly plugged into the male USB connector to charge them using the second charging / discharging module 20.

[0040] In another implementation, the first and second charging / discharging interfaces are charging / discharging contacts. When the first and second charging / discharging modules are mechanically connected, the charging / discharging contacts of the first and second charging / discharging interfaces come into contact, thus achieving electrical connection between them. Preferably, the charging / discharging contacts are magnetic charging / discharging contacts, which allows the first and second charging / discharging modules to be magnetically connected, ensuring the stability of the contact connection.

[0041] Example 2

[0042] Based on Embodiment 1, the first charging and discharging module 10 in this embodiment is provided with an additional charging and discharging module 30, and both the first charging and discharging module 10 and the additional charging and discharging module 30 are provided with at least one set of first magnetic wireless charging and discharging components.

[0043] The first charging / discharging body is provided with a first charging / discharging position 11, and the additional charging / discharging module 30 is provided with a second charging / discharging position 31. The first charging / discharging position 11 and the second charging / discharging position 31 are respectively provided with corresponding charging / discharging components, so that the first charging / discharging position 11 can charge and discharge an electronic device (such as a mobile phone), and the second charging / discharging position 31 can charge and discharge another electronic device (such as an earphone case or a wristband).

[0044] like Figure 1 , Figure 3 As shown, in this embodiment, the additional charging / discharging module 30 can extend or retract relative to the first charging / discharging module 10, allowing the additional charging / discharging module 30 to be retracted when not in use and extended when needed, thus increasing the portability of the entire device. Preferably, the first charging / discharging module 10 is provided with a storage slot, the additional charging / discharging module 30 is located in the storage slot, and can slide along the storage slot.

[0045] Example 3

[0046] Unlike Embodiments 1 and 2, the first charging and discharging module 10 in this embodiment is also equipped with a first storage battery, so that the first charging and discharging module can be used as a magnetic wireless charging bank.

[0047] Example 4

[0048] Unlike Embodiments 1 to 3, the second charging and discharging module 20 in this embodiment is further provided with one or both of a second magnetic wireless charging and discharging component and a second USB interface, so that the second charging and discharging module 20 can perform both magnetic wireless charging and discharging and USB charging and discharging functions.

[0049] Example 5

[0050] A bracket is provided on one of the first and second charging / discharging modules. The bracket can rotate relative to the first or second charging / discharging module, and when in its original position, the bracket surrounds the other of the first and second charging / discharging modules. Based on this, in this embodiment, the bracket provides support and can also be used to maintain the connection between the first and second charging / discharging modules, preventing them from separating.

[0051] Specifically, the first or second charging / discharging module is equipped with a bracket, which has a storage and support position relative to the first or second charging / discharging module. When the first and second charging / discharging modules are connected, the bracket unfolds to provide tilt support for the entire magnetic wireless power bank, facilitating tilted placement for charging and discharging of mobile phones and other electronic devices; for example... Figure 4 As shown, when the first charging / discharging module and the second charging / discharging module are used separately, the first charging / discharging module magnetically attaches to the mobile phone or power bank. Figure 4When the electronic device 50 is a magnetic charging bank, the stand can also provide support.

[0052] In this embodiment, the bracket 40 is rotatably connected to the first charging / discharging module 10. When the second charging / discharging module 20 is in the connected position relative to the first charging / discharging module 10 and the bracket 40 is in the retracted position, the bracket 40 surrounds the periphery of the second charging / discharging module 20. The first charging / discharging module 10 can be used alone for support; when the first charging / discharging module 10 and the second charging / discharging module 20 are connected, the bracket 40 can be unfolded for support; when the first charging / discharging module 10 and the second charging / discharging module 20 are connected, the bracket 40 can be retracted to securely connect the first charging / discharging module 10 and the second charging / discharging module 20.

When the first charging / discharging module and the second charging / discharging module are mechanically connected, the first charging / discharging interface and the second charging / discharging interface are electrically connected.

[0055] Corresponding to Embodiment 3 above, in order to realize the energy storage function of the first charging and discharging module, the first charging and discharging management circuit is connected to the first battery; corresponding to Embodiment 4 above, in order to realize the wireless charging and discharging and USB charging and discharging functions of the second charging and discharging module, the second charging and discharging management circuit is also electrically connected to the second magnetic wireless charging and discharging component and the second USB interface.
