The charging head is movable relative to the housing. The charging head is provided with a control component. The main body also includes a control switch corresponding to the storage compartment. The control switch is signal-connected to the display element. When the control component moves away from the storage compartment along with the charging head, it triggers the control switch to turn on the display element.

[0006] Optionally, the control element is a magnetic element, and the control switch is a Hall switch.

[0007] Optionally, a receiving groove is provided on the outer side of the housing, and the charging head is disposed in the receiving groove.

[0014] Optionally, the charging head is provided with at least one charging interface, which is a Lightning connector and / or a Micro USB connector and / or a Type-C interface.

[0015] Compared with the prior art, the portable power bank of this utility model has the following advantages:

[0016] 1. In one embodiment of this utility model, the power bank includes a main body, a charging head, and a charging cable. The charging head is electrically connected to the main body via the charging cable. The main body includes a housing and a circuit board, a display element, and a power assembly disposed within the housing. The display element and the power assembly are electrically connected to the circuit board. A storage compartment is provided on the outer side of the housing, where the charging head is stored. The charging head can move relative to the housing. The charging head is equipped with a control component, and the main body also includes a control switch corresponding to the storage compartment. The control switch is signal-connected to the display element. When the control component moves away from the storage compartment with the charging head, it triggers the control switch to turn on the display element. The display element is used to display power information. Since the charging head can move relative to the housing, and the control component is disposed on the charging head, and the control switch is signal-connected to the display element, when the control component moves away from the storage compartment and undergoes relative displacement, it triggers the control switch to turn on the display element. This establishes a control relationship between the relative displacement of the control component and the control switch and the turning on of the display element. When a user faces a charging need, they only need to pull the charging head, and the display element can quickly respond and display information. The display information is linked to the user's pulling action on the charging head, which can accurately and conveniently display the power information to the user only when the user is concerned about the remaining power. It has the advantages of simple operation, fast device response, and accurate and efficient display.

[0017] 2. In one embodiment of this utility model, the control component is a magnetic component, and the control switch is a Hall switch. Based on the Hall principle, the Hall switch is triggered by sensing changes in the magnetic field, outputting a corresponding electrical signal. When the user pulls the charging head, the charging head moves. Since the magnetic component is located on the charging head, it also moves. The Hall switch is correspondingly positioned to the magnetic component. Therefore, the Hall switch triggers the output electrical signal based on the change in the magnetic field generated by the movement of the magnetic component, thereby controlling the display element to display the remaining battery level. This allows the movement of the charging head to control the display state of the display element, enabling the user to easily and conveniently display the remaining battery level accurately and quickly.

[0018] 3. In one embodiment of this utility model, a receiving groove is provided on the outer side of the housing, and the charging head is disposed in the receiving groove. By providing a receiving groove on the outer side of the housing and disposing of the charging head in the receiving groove, the storage position is specifically a receiving groove structure, so that the receiving groove can store and fix the charging head. When the charging head is not pulled out, it can be fixed in the receiving groove and will not loosen or fall off, thereby making the overall structure of the power bank more compact and improving the stability of storage.

[0019] 4. In one embodiment of this utility model, the display element is a digital display screen or multiple indicator lights. When the display element is a digital display screen, the control component moves away from the storage position along with the charging head, triggering the control switch to turn on the digital display screen, and the power information is displayed in digital form. When the display element is multiple indicator lights, the power information is displayed by the number of indicator lights that are turned on.

[0020] 5. In one embodiment of this utility model, a magnetic suction element is provided on the inner wall of the housing corresponding to the storage position. The magnetic suction element can be magnetically connected with a magnetic component. By providing a magnetic suction element on the inner wall of the housing corresponding to the storage position, when the charging head is placed in the storage position, the magnetic suction element can be magnetically connected with the magnetic component inside the charging head, enabling the charging head to automatically align when stored. The magnetic attraction between the two enhances the stability of the charging head when stored.

[0021] 6. In one embodiment of this utility model, a telescopic mechanism is also provided inside the housing, and the charging cable is partially wound around the telescopic mechanism. Since the charging cable is partially wound around the telescopic mechanism, the telescopic mechanism allows the user to adjust the length of the charging cable as needed, so that the length of the charging cable can match the distance of the electronic device. After use, it can be retracted into the housing, which saves storage space, makes it easy to store and carry, and avoids the charging cable from getting tangled and knotted.

[0022] 7. In one embodiment of this utility model, the power bank further includes a hook assembly, which is connected to the housing. By connecting the hook assembly to the housing, the user can connect the power bank to themselves, such as to clothing or a backpack, making it easier to carry and freeing up their hands. Furthermore, because the housing is subjected to force when the charging head is pulled, the hook assembly restrains the housing, facilitating the normal pulling out of the charging head. This makes charging and checking the remaining power of the power bank more convenient for the user.

[0023] 8. In one embodiment of this utility model, the hook assembly and the housing form a first through hole. The hook assembly includes a locking rod and a fixing rod. The fixing rod includes a fixing part disposed inside the housing and an arc-shaped part disposed outside the housing. The fixing rod and the locking rod are rotatably connected. The hook assembly and the housing form a first through hole for hooking. Since the hook assembly includes a locking rod and a fixing rod, and the fixing rod includes a fixing part disposed inside the housing and an arc-shaped part disposed outside the housing, and the fixing rod and the locking rod are rotatably connected, the fixing part built into the housing can provide a stable fixing force. The user can easily rotate the locking rod with one hand, thus eliminating the need to rely on both hands to achieve the relative rotation of the locking rod and the fixing rod, thereby conveniently and quickly hooking the power bank.

[0024] 9. In one embodiment of this utility model, the hook assembly includes a hook body and a connector. The connector connects the hook body and the housing. The hook body has a second through hole, and the housing has a third through hole. The connector passes through the second through hole and the third through hole respectively to connect the hook body and the housing. Because the connector passes through the second through hole and the third through hole respectively to connect the hook body and the housing, a stable connection can be established between the hook body and the housing. The connection between the hook body and the housing through the second through hole and the third through hole also allows relative rotation between the hook body and the housing. The connection between the hook body and the housing is more flexible and free to adapt to different connection angles.

[0025] 10. In one embodiment of this utility model, the charging head is provided with at least one charging interface, which is a Lightning connector and / or a Micro USB connector and / or a Type-C interface. Since different devices may use different charging interfaces, when there is only one charging interface, the user's choice is more targeted; while when there are multiple charging interfaces of different types, charging compatibility can be improved. Providing multiple interfaces can ensure compatibility with various electronic devices, making it convenient for users to charge electronic devices of different brands and types.

[0042] Please combine Figures 1 to 5The first embodiment of this utility model provides a portable power supply 1, which includes a main body 10, a charging head 20, and a charging cable 30. The charging head 20 is electrically connected to the main body 10 through the charging cable 30. The main body 10 includes a housing 11 and a circuit board 12, a display element 13, and a power assembly 14 disposed within the housing 11. The display element 13 and the power assembly 14 are electrically connected to the circuit board 12. A storage space 111 is provided on the outside of the housing 11, in which the charging head 20 is stored. The charging head 20 is movable relative to the housing 11. The charging head 20 is provided with a control element 21. The main body 10 also includes a control switch 15 corresponding to the storage space 111. The control switch 15 is signal-connected to the display element 13. When the control element 21 moves away from the storage space 111 along with the charging head 20, it triggers the control switch 15 to turn on the display element 13.

[0043] Understandably, the display element 13 is used to display the remaining power information of the power bank 1 when it is turned on. Since the charging head 20 can move relative to the housing 11, the control element 21 is disposed on the charging head 20. The control switch 15 is signal-connected to the display element 13. When the control element 21 moves away from the storage position 111 and generates relative displacement, it triggers the control switch 15 to turn on the display element 13, thereby establishing a control relationship between the relative displacement of the control element 21 and the control switch 15 and the turning on of the display element 13. When the user faces a charging need, they only need to pull the charging head 20, and the display element 13 can quickly respond and display the remaining power information. It should be noted that... Figure 1 This shows the charging head 20 stored in storage compartment 111; Figure 2 This demonstrates the state in which the charging head 20 moves away from the storage position 111, resulting in relative displacement. The opening and closing of the display information is linked to the user's pulling action on the charging head 20. It can accurately and conveniently display the remaining power to the user only when the user is concerned about the remaining power information of the power bank 1, based on the movement of the charging head 20. It has the advantages of simple operation, fast device response, and accurate and efficient display.

[0044] Specifically, as an optional implementation, the control switch 15 and the display element 13 are connected by an electrical signal. Other signal connection methods, such as wireless signal connection, digital signal connection, and mechanical signal connection, are not limited here.

[0045] Specifically, as an optional embodiment, a display hole 116 is provided at the corresponding position of the housing 11 and the display element 13, and the display element 13 displays to the outside through the display hole 116; as another optional embodiment, the corresponding position of the housing 11 and the display element 13 is a display part 131, and the display part 131 is made of transparent material so that light from the display element 13 can pass through for display.

[0046] Specifically, as an optional implementation, the power supply assembly 14 consists of two rechargeable batteries. Users can supply power to electronic devices via the charging head 20, and can also reverse charge the rechargeable batteries via the charging head 20. The rechargeable batteries can be lithium-ion batteries, such as 18650 cylindrical batteries, and are not limited thereto.

[0047] Please combine Figure 1 , Figure 3 and Figure 5 Furthermore, the control element 21 is a magnetic element 22, and the control switch 15 is a Hall switch 16.

[0048] Understandably, the Hall switch 16 is based on the Hall principle. It is triggered by sensing changes in the magnetic field to output a corresponding electrical signal. When the user pulls the charging head 20, the charging head 20 moves. Since the magnetic component 22 is located on the charging head 20, it also moves. The Hall switch 16 is correspondingly set with the magnetic component 22. Therefore, the Hall switch 16 is triggered to output an electrical signal based on the change in the magnetic field generated by the movement of the magnetic component 22, thereby controlling the display element 13 to display the remaining power. This allows the movement of the charging head 20 to control the display state of the display element 13, enabling the user to easily and conveniently display the remaining power of the power bank 1.

[0049] Please combine Figure 1 and Figure 2 Furthermore, a receiving groove 112 is provided on the outer side of the housing 11, and the charging head 20 is disposed in the receiving groove 112.

[0050] Understandably, by providing a receiving groove 112 on the outside of the housing 11, and placing the charging head 20 in the receiving groove 112, the storage position 111 is specifically a receiving groove 112 structure, so that the receiving groove 112 can store and fix the charging head 20. When the charging head 20 is not pulled out, it can be fixed in the receiving groove 112 without loosening or falling off, thus making the overall structure of the power bank 1 more compact and improving the stability of storage.

[0051] Please combine Figure 1 and Figure 3 Furthermore, the display element 13 is a digital display screen or multiple indicator lights.

[0052] Understandably, when the display element 13 is a digital display screen, and the control element 21 moves away from the storage position 111 along with the charging head 20, the control switch 15 is triggered to turn on the digital display screen, and the power information is displayed in digital form; when the display element 13 is multiple indicator lights, the power information is displayed by the number of indicator lights that are turned on.

[0053] Please combine Figures 3 to 5Furthermore, a magnetic element 113 is provided on the inner wall of the housing 11 at the position corresponding to the storage position 111, and the magnetic element 113 can be magnetically connected to the magnetic element 22.

[0054] Understandably, by setting a magnetic member 113 at the position corresponding to the storage position 111 on the inner wall of the housing 11, when the charging head 20 is placed in the storage position 111, the magnetic member 113 can be magnetically connected with the magnetic member 22 inside the charging head 20, so that the charging head 20 can be automatically aligned when stored, and the magnetic attraction between the two can be used to improve the firmness of the charging head 20 when stored.

[0055] It should be noted that the magnetic component 113 can be made of iron or magnetic material so as to achieve magnetic connection with the magnetic component 22 inside the charging head 20.

[0056] Please combine Figure 3 and Figure 4 Furthermore, a telescopic mechanism 114 is also provided inside the housing 11, and part of the charging cable 30 is wound around the telescopic mechanism 114.

[0057] Understandably, since the charging cable 30 is partially wrapped around the telescopic mechanism 114, the telescopic mechanism 114 allows the user to adjust the length of the charging cable 30 as needed. The length of the charging cable 30 can match the distance of the electronic device, and it can be retracted into the housing 11 after use. This saves storage space, makes it easy to store and carry, and also avoids the charging cable 30 from getting tangled and knotted.

[0058] It should be noted that the telescopic mechanism 114 can adopt the telescopic structure of an existing measuring tape or telescopic charging cable 30, which will not be elaborated here.

[0059] Please combine Figure 1 and Figure 3 Furthermore, the power bank 1 also includes a hook assembly 40, which is connected to the housing 11.

[0060] Understandably, by setting the hook assembly 40 to connect with the housing 11, the user can connect to themselves through the hook assembly 40, such as to clothing, backpacks, etc., making it easier to carry the power bank 1 and freeing up their hands. Furthermore, since the housing 11 is under force when the charging head 20 is pulled, the hook assembly 40 restrains the housing 11, making it easier to pull out the charging head 20 normally. This makes it more convenient for the user to charge or check the remaining power of the power bank 1.

[0061] Please combine Figure 3 and Figure 4Furthermore, the hook assembly 40 and the housing 11 enclose a first through hole 413. The hook assembly 40 includes a locking rod 412 and a fixing rod 411. The fixing rod 411 includes a fixing part 4111 disposed inside the housing 11 and an arc-shaped part 4112 disposed outside the housing. The fixing rod 411 and the locking rod 412 are rotatably connected.

[0062] Understandably, the hook assembly 40 and the housing 11 enclose a first through hole 413 for hooking. Since the hook assembly 40 includes a locking rod 412 and a fixing rod 411, the fixing rod 411 includes a fixing part 4111 disposed inside the housing 11 and an arc-shaped part 4112 disposed outside the housing 11. The fixing rod 411 and the locking rod 412 are rotatably connected, so that the fixing part 4111 built into the housing 11 can provide a stable fixing force. The user can easily rotate the locking rod 412 with one hand, so that the user does not need to rely on both hands to achieve the relative rotation of the locking rod 412 and the fixing rod 411, thus making it convenient and quick to hook the power bank 1.

[0063] Please continue to combine Figure 1 and Figure 3 Furthermore, the charging head 20 is provided with at least one charging port 23, which is a Lightning connector and / or a Micro USB connector and / or a Type-C interface.

[0064] Understandably, since different devices may use different charging ports 23, when there is only one charging port 23, the user's choice is more targeted; while when there are multiple different types of charging ports 23, charging compatibility can be improved. Providing multiple types of charging ports 23 can ensure compatibility with various electronic devices, making it convenient for users to charge electronic devices of different brands and types.

[0065] Please see Figure 6 The second embodiment of this utility model provides a mobile power supply 1a, which differs from the mobile power supply 1 of the first embodiment of this utility model in that the hook assembly 40 includes a hook body 41 and a connector 42. The connector 42 connects the hook body 41 and the housing 11. The hook body 41 has a second through hole 414, and the housing 11 has a third through hole 115. The connector 42 passes through the second through hole 414 and the third through hole 115 respectively to connect the hook body 41 and the housing 11.

[0066] Understandably, since the connector 42 passes through the second through hole 414 and the third through hole 115 respectively to connect the hook body 41 and the housing 11, the hook body 41 and the housing 11 can establish a stable connection relationship. The connection of the connector 42 through the second through hole 414 and the third through hole 115 also allows the hook body 41 and the housing 11 to rotate relative to each other. The connection relationship between the hook body 41 and the housing 11 is more flexible and free to adapt to different connection angles.

[0071] 4. In one embodiment of this utility model, the display element is a digital display screen or multiple indicator lights. When the display element is a digital display screen, the control component moves away from the storage position along with the charging head, triggering the control switch to turn on the digital display screen, and the power information is displayed in digital form. When the display element is multiple indicator lights, the power information is displayed by the number of indicator lights that are turned on.

[0072] 5. In one embodiment of this utility model, a magnetic suction element is provided on the inner wall of the housing corresponding to the storage position. The magnetic suction element can be magnetically connected with a magnetic component. By providing a magnetic suction element on the inner wall of the housing corresponding to the storage position, when the charging head is placed in the storage position, the magnetic suction element can be magnetically connected with the magnetic component inside the charging head, enabling the charging head to automatically align when stored. The magnetic attraction between the two enhances the stability of the charging head when stored.

The fixing rod includes a fixing part disposed inside the housing and an arc-shaped part disposed outside the housing. The fixing rod and the locking rod are rotatably connected. The hook assembly and the housing form a first through hole for hooking. Since the hook assembly includes a locking rod and a fixing rod, and the fixing rod includes a fixing part disposed inside the housing and an arc-shaped part disposed outside the housing, and the fixing rod and the locking rod are rotatably connected, the fixing part built into the housing can provide a stable fixing force. The user can easily rotate the locking rod with one hand, thus eliminating the need to rely on both hands to achieve the relative rotation of the locking rod and the fixing rod, thereby conveniently and quickly hooking the power bank.

[0076] 9. In one embodiment of this utility model, the hook assembly includes a hook body and a connector. The connector connects the hook body and the housing. The hook body has a second through hole, and the housing has a third through hole. The connector passes through the second through hole and the third through hole respectively to connect the hook body and the housing. Because the connector passes through the second through hole and the third through hole respectively to connect the hook body and the housing, a stable connection can be established between the hook body and the housing. The connection between the hook body and the housing through the second through hole and the third through hole also allows relative rotation between the hook body and the housing. The connection between the hook body and the housing is more flexible and free to adapt to different connection angles.

[0077] 10. In one embodiment of this utility model, the charging head is provided with at least one charging interface, which is a Lightning connector and / or a Micro USB connector and / or a Type-C interface. Since different devices may use different charging interfaces, when there is only one charging interface, the user's choice is more targeted; while when there are multiple charging interfaces of different types, charging compatibility can be improved. Providing multiple interfaces can ensure compatibility with various electronic devices, making it convenient for users to charge electronic devices of different brands and types.

[0078] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
