[0002] In the rapidly developing consumer electronics market, various portable electronic devices such as smart phones, tablet computers, and Bluetooth earphones have become an indispensable part of people's daily lives. With the popularization of portable electronic devices, higher requirements are also put forward for the diversity and functionality of charging devices. At present, although there are a wide variety of charger heads on the market, they generally have problems such as single function, insufficient portability, low intelligence level, and poor user experience. Specifically, most traditional charger heads only support fixed or limited charging interface combinations and cannot flexibly meet the charging needs of diverse electronic devices, resulting in users having to carry multiple chargers, increasing the burden of traveling. At the same time, most charging devices lack intelligent monitoring and protection mechanisms and cannot automatically cut off power when the battery is fully charged, posing potential safety hazards and having an adverse impact on battery life. In terms of portability, although some charger heads have reduced their volume through design optimization, their limitations are still significant in the scenario of charging multiple devices and they have not really solved the pain point of users carrying multiple chargers. In addition, although there are also split charger heads on the market, they also have deficiencies in the flexibility of the charging direction and are difficult to freely adjust the direction of the charging cable according to the specific needs of users, affecting the convenience of use. More critically, the deficiencies of traditional charger heads in user experience are becoming increasingly prominent. During the charging process, users often need to perform other operations simultaneously, such as watching videos and video calls.

[0041] Please refer to Figures 1 to 6 , the embodiment of the present utility model provides a detachable multi-purpose charging head, including:

[0042] Charging main head 10, on which a retractable first plug connector 11 is provided, and a first sensing part is installed inside the charging main head 10.

[0043] The charging plug head 20 is rotatably installed on the main charging head 10 to achieve flexible connection with the main charging head 10 and is electrically connected to the main charging head 10 to ensure smooth power transmission.

[0044] The secondary charging head 30 is detachably installed on the main charging head 10 and is arranged beside the charging plug head 20. It not only optimizes the structural space and improves the portability in the multi-device charging scenario but also facilitates replacing the secondary charging head 30 with different functions according to needs to flexibly meet the charging requirements of diverse electronic devices. The secondary charging head 30 is also snap-connected to the charging plug head 20 to enhance the structural connection stability. On one side of the main charging head 10 close to the secondary charging head 30, there is a socket 12. One end of the secondary charging head 30 is provided with a plug block 31 adapted to the socket 12 to achieve rapid charging splicing and docking. The other end of the secondary charging head 30 is provided with a second plug 32. The designs of the first plug 11 and the second plug 32 not only meet the requirement of coordinated charging work when the main charging head 10 and the secondary charging head 30 are spliced but also meet the requirement of independent charging work when they are separated, further improving the charging flexibility of diverse electronic devices. Inside the socket 12, there is a support cross plate 13. A conductive pin 14 is installed on the support cross plate 13. A conductive socket hole 311 corresponding to the conductive pin 14 is opened on the plug block 31 to ensure precise conductive docking and realize the effective transfer of power from the main charging head 10 to the secondary charging head 30 or other adapted electronic devices. On both sides of one end of the socket 12 close to the secondary charging head 30, there are also retractable support members 40 installed to provide an additional function of support to meet the user's other operations during charging, such as watching videos or making video calls using electronic devices, improving the user experience. A second sensing component is also installed inside the secondary charging head 30.

[0045] The charging control component 50 is movably installed in the socket 12 and is arranged on the side of the support cross plate 13 away from the plug block 31. The charging control component 50 is used to control the conduction and interruption of the conductivity between the main charging head 10 and the conductive pin 14 to achieve charging on-off control and extend the service life of the device.

[0046] The sealing plate 60 is installed on the side of the main charging head 10 away from the charging plug head 20. On one side of the sealing plate 60 close to the socket 12, there is also a power component 70 for driving the charging control component 50. Inside the main charging head 10, there is also a micro energy storage control component. The first sensing component and the second sensing component are electrically connected to the micro energy storage control component. The micro energy storage control component is also electrically connected to the power component 70 to realize real-time processing and feedback of charging, thereby precisely controlling the operation of the charging control component 50. There is also a mechanical cut-off component on the second plug 32, and the mechanical cut-off component is used to control the on-off of the second sensing component.

[0047] Specifically, if the main charging head 10 and the secondary charging head 30 work together, that is, they become an integral component at this time. When the first plug connector 11 or the second plug connector 32 is connected to the power supply, through the first sensing member or the second sensing member, the power member 70 can be driven to work, controlling the charging control component 50 to conduct the circuit for charging operation. When it is detected that the electronic product device is fully charged, the power member 70 cuts off the drive to the charging control component 50, and the main charging head 10 disconnects from the conductive pin 14, and the circuit is turned off. In addition, if the main charging head 10 and the secondary charging head 30 are disassembled and work independently, the main charging head 10 can control the charging control component 50 to work through the first sensing member. To avoid the secondary charging head 30 interfering with the normal operation of the main charging head 10, it is necessary to cut off the connection between the second sensing member and the power member 70 through a mechanical shut-off member.

[0048] In this embodiment, the charging control component 50 includes:

[0049] The guiding column rod 51, as the core support structure, is arranged on the side of the support cross plate 13 away from the conductive pin 14 and is fixedly connected to the support cross plate 13.

[0050] The conductive control member 52 is sleeved and installed on the guiding column rod 51 and can reciprocate along the axial length direction of the guiding column rod 51. The design of the guiding column rod 51 ensures the stability and positioning accuracy of the overall structure, providing a reliable guiding reference for the precise movement of the conductive control member 52. On the side of the conductive control member 52 close to the support cross plate 13, there is a first conductive convex column 521 corresponding to the conductive pin 14 to ensure the effective transmission of electricity when the circuit is conducted. On both sides of the conductive control member 52, there are also convex first conductive bumps 522. The first conductive bumps 522 are electrically connected to the first conductive convex column 521. On both sides of the insertion slot 12, there are guide chutes 121 corresponding to the first conductive bumps 522. On the side of the guide chute 121 close to the support cross plate 13, there is a second conductive bump 122. The second conductive bump 122 is electrically connected to the main charging head 10. It should be clear that the first conductive bump 522 further enhances the conductivity and can form an electrical connection relationship with the second conductive bump 122 to construct an efficient and stable current path, not only improving the charging control on-off efficiency but also ensuring the safety of the charging process. The conductive control member 52 is a magnetic control member, and the power member 70 is an electromagnet. The power member 70 is used to provide a reverse magnetic force for the magnetic control member to achieve precise control of the moving direction of the conductive control member 52, ensuring the reliability of the charging on-off control. Moreover, the non-contact control method not only simplifies the mechanical structure but also reduces wear, improving the reliability and service life of the system structure.

[0051] The elastic member 53 is disposed between the conductive control member 52 and the support cross plate 13 and sleeved on the guide column rod 51, providing the necessary buffering and reset force for the movement of the conductive control member 52. When the conductive control member 52 moves under the action of an external magnetic force, the elastic member 53 can effectively absorb the impact energy and protect each component from damage. After the magnetic force disappears, the elastic member 53 can quickly return to its original shape and reset the conductive control member 52 to the initial state, preparing for the next charging operation. This design not only improves the fluency of the user experience but also enhances the durability and stability of the system.

[0052] The conductive pin 14, as a key component for power transmission, includes a conductive pin core 141, a conductive pin cap 142, and a mounting column member 143 mounted on the support cross plate 13. An installation through hole 144 is axially formed in the center of the mounting column member 143, and the installation through hole 144 penetrates the support cross plate 13. The conductive pin 14 is installed in the installation through hole 144. The conductive pin cap 142 is disposed at one end of the mounting column member 143 away from the support cross plate 13 and fixedly connected to one end of the conductive pin core 141. The setting of the conductive pin cap 142 protects the conductive pin core 141 while ensuring conductivity, avoiding wear caused by multiple plugging and unplugging fits with the charging sub-head 30 and affecting the conductive accuracy. An abutting groove 145 for cooperating with the first conductive convex column 521 is formed at the other end of the conductive pin core 141, realizing a seamless connection during the power transmission process and avoiding energy loss and safety hazards caused by poor contact. During charging, the first conductive convex column 521 can smoothly embed into the abutting groove 145 to form a stable conductive path, ensuring that power can be efficiently and safely transmitted to the device to be charged.

[0053] The conductive control member 52 includes a first insulating layer 523, a conductive layer 524, a second insulating layer 525, and a magnetic layer 526 connected in sequence. Among them, the first insulating layer 523, as the outermost protective layer, effectively isolates the potential influence of the external environment on the internal conductive structure, ensuring the safe operation of the conductive control member 52. The conductive layer 524 is disposed between the first insulating layer 523 and the second insulating layer 525 and serves as the main channel for power transmission, realizing the efficient and stable flow of current. The second insulating layer 525 is located between the conductive layer 524 and the magnetic layer 526, playing a dual insulation role and further enhancing the safety performance of the conductive control member 52, preventing safety hazards such as short circuits or electric leaks caused by faults. The first conductive convex column 521 passes through the first insulating layer 523 and is connected to the conductive layer 524, ensuring that power can be smoothly accessed from the outside and conducted to the conductive layer 524. The first conductive bumps 522 are disposed on both sides of the conductive layer 524 and fixedly connected to the conductive layer 524, providing a more reliable guarantee for power transmission control.

[0054] Furthermore, a conductive contact 61 is also provided on the side of the sealing plate 60 close to the main charging head 10. The conductive contact 61 is used to connect the power component 70 and the micro energy storage control component. A conductive contact point 15 corresponding to the conductive contact 61 is also provided on the main charging head 10. The conductive contact 61 and the conductive contact point 15 are in close cooperation to form a stable and reliable circuit connection, providing a solid guarantee for power transmission.

[0055] On the side of the main charging head 10 close to the charging plug head 20, a first storage groove 16 is also formed. The first storage groove 16 is located below the charging plug head 20, providing a safe and stable storage environment for the first plug connector 11. The first plug connector 11 is rotatably installed in the first storage groove 16, optimizing the structural space and improving portability. Slots 161 are also formed on both side walls of the first storage groove 16, and a cover 18 is detachably installed on the slots 161, further enhancing the aesthetics and practicality of the charging head. The detachable installation method of the cover 18 facilitates the user to quickly close it when the first plug connector 11 is not in use, preventing damage caused by external factors such as dust and moisture. At the same time, the close cooperation between the slots 161 and the cover 18 ensures the sealing performance of the storage groove and extends the service life of the first plug connector 11.

[0056] On the side of the first storage groove 16 close to the charging plug head 20, a first groove is also formed. A first magnetic attraction block is provided at the bottom of the first groove. A second magnetic attraction block 181 adapted to the slots 161 is provided on the cover 18. The second magnetic attraction block 181 is magnetically connected to the first magnetic attraction block, realizing the quick fixing and detachment of the cover 18. An operation groove 182 is also formed on the cover 18, providing a convenient operation space for the user, enabling easy force application when detaching or installing the cover 18, and further improving the user experience.

[0057] Furthermore, a second storage groove 19 corresponding to the bracket member 40 is also formed on the main charging head 10. This design not only makes clever use of the space of the main charging head 10 but also realizes the convenient storage and quick deployment of the bracket member 40. The second storage groove 19 is arranged on both sides of the insertion slot 12 and is parallel, ensuring the stability of the bracket member 40 in the storage state and facilitating the user to carry out the deployment operation according to needs. One end of the bracket member 40 far from the charging plug head 20 is rotatably connected to the main charging head 10, enabling the bracket member 40 to flexibly adjust the angle to adapt to the stability requirements for placing different electronic devices. The other end is provided with a limiting convex block 41, further improving the stability and safety of placing the electronic device.

[0058] On the side of the charging plug head 20 close to the auxiliary charging head 30, a clamping block 21 is also provided. A clamping groove 33 corresponding to the clamping block 21 is formed on the auxiliary charging head 30, which not only simplifies the connection process but also improves the connection stability and reliability, ensuring the stability and safety during the charging process.

[0059] On the side of the charging plug head 20 far away from the secondary charging head 30, there is a charging plug socket 23. On the side of the clamping block 21 far away from the charging plug socket 23, there is a micro suction cup 22. When the main charging head 10 is used alone, rotate the charging plug head 20 so that the micro suction cup 22 and the first plug connector 11 are on the same side. When plugging in for charging in a specific scenario, it can firmly adsorb on the desktop or other planes, improving the stability of the charging installation of the main charging head 10 and avoiding the phenomenon that the main charging head 10 detaches from the charging socket or drops and is damaged due to accidental touch. The depth of the engaging groove 33 is not less than the sum of the axial dimensions of the clamping block 21 and the micro suction cup 22, avoiding interference of components during the insertion process and damaging the micro suction cup 22.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
