Electronic equipment Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] See Figures 1 to 17 As shown, this utility model provides an embodiment of a multifunctional charging device, including: a wireless power supply base 1, an input cable 2, an input head 3, and an output cable assembly 4; the wireless power supply base 1 includes a housing 11, a printed circuit board 12 installed in the housing 11, and a wireless power supply module 13, the printed circuit board 12 being electrically connected to the input cable 2, the output cable assembly 4, and the wireless power supply module 13; the output cable assembly 4 and the input head 3 both extend out of the housing 11; the input cable 2 is a retractable cable, wound inside the housing 11, and passes through an opening 14 provided on the housing 11 to connect to the input head 3.

[0039] Specifically, the multifunctional charging device disclosed in this embodiment includes a wireless power supply base 1, an input cable 2, an input connector 3, and an output cable assembly 4. The wireless power supply base 1 is the core component of the entire charging device, comprising a housing 11, a printed circuit board 12 installed within the housing 11, and a wireless power supply module 13. The printed circuit board 12 serves as the circuit control center, electrically connected to the input cable 2, the output cable assembly 4, and the wireless power supply module 13, realizing the input, distribution, and conversion of electrical energy. The input cable 2 is a retractable cable, coiled and stored within the housing 11, which facilitates cable storage, avoids clutter, maintains neatness, saves space, and is easy to organize. After the input cable 2 is connected to an external power source through the input connector 3, electrical energy is transmitted through the printed circuit board 12. The wireless power supply module 13 supplies power to electronic devices 7 that support wireless charging, while the output cable assembly 4 provides power to electronic devices 7 that require wired charging. The multifunctional charging device provided by this utility model integrates wireless charging and wired charging functions, which can meet the charging needs of different electronic devices 7; at the same time, the winding and storage design of the input cable 2 solves the problem of the input cable 2 getting tangled in traditional charging devices, making it easy to store and use.

[0040] See Figure 6 As shown, in one embodiment, a winding mechanism 5 is provided inside the housing 11, and the input wire 2 is wound around the winding mechanism 5.

[0041] Specifically, in this embodiment, the housing 11 is equipped with a winding mechanism 5, around which the input cable 2 is wound. The winding mechanism 5 is designed to automatically retract and release the input cable 2 using a mechanical structure. It typically contains an elastic element; when the input cable 2 is pulled out for use, the elastic element is stretched and stores energy; after use, the elastic element releases energy, causing the winding mechanism 5 to automatically retract the input cable 2. When the user uses the device, they pull out the input cable 2 to connect to the power source; after use, the input cable 2 automatically retracts into the housing 11 under the action of the winding mechanism 5. The technical effect of this design is to further optimize the storage function of the input cable 2, making its storage more convenient and efficient, reducing the hassle of manually organizing the input cable 2, and preventing damage due to careless placement. It is understood that in this embodiment, the elastic element in the winding mechanism 5 can be any of the following elastic structures: spring, coil spring, or sheet spring. When charging is required, the user overcomes the elastic force of the winding mechanism 5 to pull out the input cable 2, and after charging is complete, the winding mechanism 5 retracts the input cable 2. The design of the winding mechanism 5 can be adjusted according to different cable lengths and stretching requirements to ensure smooth and flexible extension and retraction. It is also understood that, in this embodiment, the more specific structure and working principle of the winding mechanism 5 can be found in common existing technologies such as spring-type, coil-spring type, and spring-plate type winding machines; their specific working principles will not be elaborated here.

[0042] See Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in one embodiment, the housing 11 is provided with a first storage slot 16, and the input head 3 is magnetically connected to or / and snapped into the first storage slot 16.

[0043] Specifically, the input head 3, as a key component connecting the external power supply and the input cable 2, is fixed to the input cable 2, reducing contact problems caused by frequent plugging and unplugging of the input head 3. Placing the input head 3 in the first storage slot 16 further ensures the safety and integrity of the input head 3 when not in use. The magnetic connection and / or snap-fit ​​design allows the input head 3 to be stably fixed in the first storage slot 16. When the user needs to connect the input head 3 to the power supply, they can simply pull the input head 3 out of the first storage slot 16, which is convenient. This design not only facilitates the storage of the input head 3, but also ensures that the input head 3 will not accidentally fall out of its storage position during carrying, avoiding damage. This design enhances the stability and reliability of the input head 3 storage. Compared with simple placement or ordinary fixing methods, the magnetic connection and / or snap-fit ​​method can better cope with shaking and bumps during carrying, preventing the input head 3 from falling out of the first storage slot 16 due to external force. Meanwhile, it simplifies user operation, allowing for quick removal of the input head 3 when needed and easy return for storage, thus improving user efficiency in using the charging device. Furthermore, it reduces the risk of damage to the input head 3 due to accidental collisions or detachment, extending its lifespan and ensuring the overall normal operation of the charging device, thereby enhancing the product's comprehensive performance and user satisfaction. Understandably, the first storage slot 16 can adopt different shapes and sizes to accommodate different types of input heads 3.

[0044] In one embodiment, the opening 14 is located inside the first storage slot 16.

[0045] Specifically, by placing the opening 14 inside the first storage slot 16, the input cable 2 follows a more regular path when stored, preventing excessive bending or twisting of the input cable 2 outside the housing 11 and reducing the exposure of the input cable 2 during storage, thus effectively protecting the input cable 2. During operation, the input cable 2 enters and exits the housing 11 through the opening 14 inside the first storage slot 16; it is pulled out when in use and retracted when stored, moving along a more reasonable path throughout the process. The technical effect of this design is to effectively protect the input cable 2, extend its service life, and make the charging device look cleaner and more aesthetically pleasing.

[0046] See Figure 1 , Figure 2 and Figures 9 to 12As shown, in one embodiment, the output line group 4 includes a first output line 41, a first output head 42, and a connector 43; one end of the first output line 41 is connected to the wireless power supply 1, and the other end is connected to the first output head 42; the connector 43 is sleeved on the first output line 41 and is detachably connected to the first output head 42.

[0047] Specifically, in this embodiment, the output cable assembly 4 includes an output cable and an output head, namely a first output cable 41 and a first output head 42. By connecting the connector 43 to the first output cable 41 and detachably connecting it to the first output head 42, a single output cable and a single output head can be detachably connected to the connector 43 to form an openable loop, thereby forming a lanyard structure for easy storage and carrying, while also preventing the input cable 2 from getting tangled. This design breaks through the limitation of traditional charging devices that only focus on charging functions, innovatively transforming the output cable assembly 4 into a portable tool, achieving improved portability with a simple and ingenious structure. Furthermore, it ensures the connection stability of the first output cable 41 and the first output head 42 with the connector 43, thus ensuring the structural stability of the openable loop, while also allowing users to conveniently use the input head 3. This not only meets the needs of diverse charging scenarios but also enhances the convenience and flexibility of using the charging device, effectively improving the user experience. In addition, since the first output line 41 is connected to the wireless power supply base 1, the connector 43 and the first output head 42 at the same time, it effectively prevents parts from falling off. This stable connection method greatly improves the reliability of the charging device in complex usage environments. Whether it is frequent use when carrying it with you in daily life or external impact caused by bumps and vibrations in sports scenarios, each component can maintain a stable connection, avoiding the risk of interruption or loss of use due to accidental falling off of parts, and making it convenient to store and use the charging device.

[0048] See Figures 3 to 5 and Figures 13 to 15 As shown, in one embodiment, the output line group 4 further includes a second output line 44 and a second output head 45; one end of the second output line 44 is connected to the wireless power supply base 1, and the other end is connected to the second output head 45; the second output head 45 can also be detachably connected to the connector 43.

[0049] Specifically, in this embodiment, the output cable group 4 includes two sets of output cables and output heads, namely, a first output cable 41, a second output cable 44, a first output head 42, and a second output head 45. By setting multiple output cables and multiple output heads, the user's need to charge multiple different types of electronic devices 7 simultaneously can be met. Meanwhile, the first output head 42 and the second output head 45 are designed to be detachably connected to the connector 43, facilitating the storage and management of the output cables and improving the portability of the charging device. When stored, the first output head 42 and the second output head 45 are respectively connected to the connector 43, so that the first output cable 41 and the second output cable 44 naturally form an openable loop with the connector 43, and form an integral part with components such as the wireless power supply 1. In use, the corresponding output head can be detached from the connector 43 as needed and connected to the corresponding electronic device 7, and the power from the wireless power supply 1 is transmitted to the electronic device 7 for charging via the output cable. This design increases the functional diversity of the charging device, meets various user charging needs, and is easy to carry and use, improving the user experience.

[0050] In one embodiment, the connector 43 is snapped onto the first output head 42 and / or the second output head 45; and / or, the connector 43 is magnetically connected to the first output head 42 and / or the second output head 45.

[0051] See Figures 9 to 12 As shown, specifically, when the output line group 4 includes only one output line (i.e., the first output line 41) and one output head (i.e., the first output head 42), and is provided with a connector 43, the connector 43 is provided with a first receiving groove 431 and a first socket hole 432 on both sides respectively. The first output line 41 passes through the first socket hole 432, and the first output head 42 is snapped and / or magnetically connected to the first receiving groove 431.

[0052] This design offers multiple benefits. Firstly, the first receiving slot 431 securely holds the first output head 42 via a snap-fit ​​or magnetic connection, preventing it from shifting or getting lost when idle, while also facilitating quick user access. Secondly, the first socket 432 allows the first output wire 41 to pass through, neatly routing the wires, preventing tangling and knots, reducing wear and tear, and preventing the connector 43 from falling off. Together, these two features optimize the storage and management of the output wire group 4, improving the device's tidiness, while also ensuring stable connection during charging, reducing contact problems caused by shaking, and greatly enhancing the user experience and device usability.

[0053] Furthermore, when the first output head 42 is engaged with the first receiving slot 431, the first output head 42 includes a connecting end 421 and an output end 422 connected to the connecting end 421. The connecting end 421 is also connected to the first output line 41. The first receiving slot 431 includes a engaging section 4311 and a protective section 4312 communicating with the engaging section 4311. The connecting end 421 is engaged with the engaging section 4311, and the output end 422 is located within the protective section 4312, with a gap 4313 between it and both sides of the protective section 4312. The connecting end 421 cooperates with the engaging section 4311 to achieve a stable engagement, ensuring a secure connection between the first output head 42 and the connector 43, and guaranteeing the structural reliability of the charging device during carrying and use. The output end 422, located within the protective section 4312, can effectively block external forces such as collisions and scratches, protecting the output end 422 from damage. Based on this, a gap 4313 is intentionally provided between the protective section 4312 and the output end 422. This design aims to reduce the contact area between the output end 422 and the protective section 4312 while ensuring the protective effect, thereby reducing the frictional resistance between them when picking up and placing the first output head 42. This makes the picking up and placing of the output head smoother and more convenient, while also reducing wear caused by friction and extending the service life of the output head. This achieves a balance between stable connection, effective protection, and convenient operation. This design enables the charging device to have good protective performance and structural stability while providing a better human-computer interaction experience, meeting users' needs for convenient and efficient charging devices.

[0054] More specifically, the connection between the snap-fit ​​section 4311 and the protective section 4312 is inclined or arc-shaped, and the size of the snap-fit ​​section 4311 is smaller than the size of the protective section 4312.

[0055] Specifically, this solution uses the size difference to form a stepped limiting structure by making the snap-fit ​​section 4311 smaller than the protective section 4312. When the connecting end 421 is snapped into the snap-fit ​​section 4311, it can form a stable positioning, preventing the connecting end 421 from lateral displacement on the connector 43 and ensuring the reliability of the connection. Meanwhile, the larger space of the protective section 4312 provides sufficient space for the output end 422, avoiding excessive compression between the output end 422 and the protective section 4312. Meanwhile, the connection between the snap-fit ​​section 4311 and the protective section 4312 is inclined or curved. This serves two purposes: firstly, it guides the connecting end 421 to enter the snap-fit ​​section 4311 more smoothly when the first output head 42 is snapped into the connector 43, reducing insertion difficulty and minimizing wear caused by forced insertion; secondly, the inclined or curved transition effectively avoids stress concentration, allowing the force to be more evenly distributed between the snap-fit ​​section 4311 and the protective section 4312 when subjected to external pulling or vibration, enhancing the overall structural durability. This ensures a stable connection while balancing protective performance and ease of operation. When storing the first output head 42, the user aligns the connecting end 421 with the snap-fit ​​section 4311 from the protective section 4312 end. Due to the inclined or curved design at the connection between the snap-fit ​​section 4311 and the protective section 4312, the connecting end 421 will easily slide into the snap-fit ​​section 4311 under guidance until it is fully engaged. At this point, the output end 422 smoothly enters the protective section 4312. Thanks to the larger size of the protective section 4312, the output end 422 can be stably placed within it without making close contact with it. During transport, the locking segment 4311 limits the connection end 421, and the protective section 4312 protects the output end 422, ensuring that the first output head 42 is securely fixed to the connector 43. When the first output head 42 needs to be used, the user holds the output end 422 and pulls it outward. The stepped structure of the locking segment 4311 and the protective section 4312 does not obstruct the pulling operation too much, and the inclined or curved connection also helps reduce friction during pulling, allowing the first output head 42 to be quickly and easily detached from the connector 43 and connected to the electronic device 7 for charging. After use, the first output head 42 is snapped back into the connector 43 according to the storage steps.

[0056] Furthermore, when the first output head 42 is magnetically connected to the first receiving groove 431, the connector 43 is embedded with the first magnetic attractor 433, and the first magnetic attractor 433 is located at the bottom of the first receiving groove 431, and the first magnetic attractor 433 is magnetically connected to the first output head 42.

[0057] Specifically, the presence of the first magnetic chuck 433 eliminates the need for precise alignment and complex operations when connecting the connector 43 to the first output head 42. When the first output head 42 approaches the bottom of the first receiving slot 431 of the connector 43, the magnetic force generated by the first magnetic chuck 433 automatically attracts it into place. Users can simply bring it close to complete the connection, significantly saving connection time. This is especially suitable for neat and portable storage, greatly improving ease of use. When not in use, the first output head 42 can be easily stored in the first receiving slot 431 of the connector 43 using the magnetic force of the first magnetic chuck 433. This automatic attraction and storage method avoids the output cable group 4 being randomly placed and tangled, making the storage of the output cable group 4 more neat and orderly, facilitating quick organization and storage for users. It also helps protect the output head and output cable, extending their service life. This design combines the convenience of magnetic connection with the positioning and fixing function of the first receiving slot 431, bringing users a smoother and easier experience throughout the entire process from connection and use to storage. It meets the needs of modern users for convenient and efficient products, and enhances the product's market competitiveness and user satisfaction.

[0058] See Figures 13 to 15 As shown, when the output line group 4 includes two output lines (i.e., the first output line 41 and the second output line 44) and two output heads (i.e., the first output head 42 and the second output head 45), the connector 43 is provided with a second receiving groove 434 and a third receiving groove 435 on both sides, and the third receiving groove 435 is connected to the second socket hole 436; the first output line 41 passes through the second socket hole 436, the first output head 42 is snapped and / or magnetically connected to the third receiving groove 435; the second output head 45 is snapped and / or magnetically connected to the second receiving groove 434.

[0059] Specifically, the two independent second and third receiving slots 434 and 435 on both sides respectively fix the second output head 45 and the first output head 42, respectively. A snap-fit ​​or magnetic connection ensures secure storage and prevents the output heads from being lost or shaken. The first output wire 41 passes through the second socket 436, rationally planning the route and avoiding cable tangling and knots, reducing the risk of wire wear. Together, these two features not only optimize the storage layout of the output wire group 4, improving the device's neatness and portability, but also ensure stable connection during charging, reducing poor contact caused by shaking, and greatly improving the device's reliability and user convenience.

[0060] It is understandable that the structures of the second receiving groove 434 and the third receiving groove 435 can be the same as those of the first receiving groove 431, or they can be different.

[0061] Furthermore, when the second receiving groove 434 and the third receiving groove 435 are magnetically connected to the second output head 45 and the first output head 42 respectively, the connector 43 has a second magnetic suction member 437 embedded between the second receiving groove 434 and the third receiving groove 435, and the second magnetic suction member 437 is magnetically connected to the second output head 45 and the first output head 42.

[0062] This design achieves magnetic connection between the second receiving slot 434, the third receiving slot 435, and the output head by embedding a second magnetic element 437 within the connector 43, offering several advantages. The magnetic connection makes the storage and retrieval of the second output head 45 and the first output head 42 more convenient, allowing for fixation and disassembly without complex operations. Compared to other connection methods, magnetic adsorption offers high stability, preventing the output head from falling off during device movement and carrying, thus reducing the risk of loss.

[0063] In one specific embodiment, the connection between the first output line 41 and the first socket 432 or the second socket 436 can be a sliding connection or a fixed connection.

[0064] Specifically, when the first output line 41 is slidably connected to the first socket 432 or the second socket 436, the user can freely adjust the position of the connector 43 on the first output line 41 according to actual usage needs. This facilitates adjusting the distance between the first output head 42 and the connector 43 when the first output head 42 is detached from the connector 43, preventing the connector 43 from obstructing the connection between the first output head 42 and the electronic device 7. If the first output line 41 is fixedly connected to the first socket 432 or the second socket 436, the position of the connector 43 on the first output line 41 is relatively fixed, ensuring the structural stability of the detachable ring formed by the connection between the output line and the connector 43.

[0065] See Figures 16 to 17 As shown, in one embodiment, the housing 11 is provided with a second storage slot 17; the output cable group 4 includes a third output cable 46 and a third output head 47, one end of the third output cable 46 is connected to the wireless power supply base 1, and the other end is connected to the third output head 47; the third output head 47 is detachably connected to the second storage slot 17.

[0066] Specifically, in this embodiment, a second storage slot 17 is provided on the housing 11, and a corresponding third output cable 46 and a third output head 47 are provided. The design principle is to better store and manage the output cable group 4. The third output head 47 is detachably connected to the second storage slot 17. When not in use, the third output head 47 can be stored in the second storage slot 17, so that the third output cable 46 forms an openable and closable loop, thereby forming a hanging rope structure to keep the device neat and easy to carry and use.

[0067] When the third output cable 46 is needed to charge the electronic device 7, the third output head 47 is removed from the second storage slot 17 and connected to the charging port of the electronic device 7. The third output cable 46 obtains power from the wireless power supply jack 1 and transmits it to the electronic device 7. After use, the third output head 47 is detached from the electronic device 7 and placed back into the second storage slot 17 for storage. It is understood that the detachable connection between the third output head 47 and the second storage slot 17 can be one or a combination of snap-fit, magnetic connection, and other detachable connection methods.

[0068] When the third output head 47 is engaged in the second storage slot 17, the structure of the third output head 47 is consistent with the structure of the first output head 42 and the second output head 45. The structure of the second storage slot 17 is consistent with the structure of the first receiving slot 431, both including a engaging section 4311 and a protective section 4312. The second storage slot 17 is also provided with a cable engaging part 18 connected to the engaging section 4311, and the third output line 46 is engaged in the cable engaging part 18. The engaging section 4311 and the protective section 4312 can securely fix the third output head 47. The protective section 4312 protects the output head from external damage. At the same time, the reasonable design between the two reduces friction, facilitates handling, and extends service life. The cable engaging part 18 can fix the third output line 46, so that the third output line 46 and the housing 11 form an openable loop, which is convenient for carrying and use. It also prevents the third output head 47 from falling off the housing 11 due to pulling, and also prevents the third output line 46 from shaking and getting tangled. This design not only enables the orderly storage and management of the third output head 47 and the cable, but also improves the reliability and convenience of using the charging equipment.

[0069] In one embodiment, the output line group 4 is equipped with a display screen (not shown in the figure).

[0070] Specifically, the first output head 42, the second output head 45, and the third output head 47 are all equipped with display screens. These screens display one or more pieces of information, such as power, voltage, current, battery level, charging protocol, charging symbol, and brand logo. The display screens on the output heads provide real-time and intuitive presentation of key parameters such as power, voltage, and current, facilitating user monitoring of the device's operating status. The display of the charging protocol and symbol ensures compatibility and prevents charging anomalies. The brand logo enhances product recognition and brand awareness, while the battery level display clearly shows the energy storage status. This integration of multiple information displays improves ease of use and safety, while also optimizing the user experience through visual interaction, helping users efficiently grasp the device's operating information.

[0071] See Figure 2 As shown, in one embodiment, the housing 11 is also connected to a bracket 6; the connection between the housing 11 and the bracket 6 is a fixed connection or a detachable connection.

[0072] Specifically, one side of the housing 11 is magnetically connected to the electronic device 7 for wireless charging, while the other side is connected to the stand 6. The design principle of the stand 6 is based on a deep consideration and functional integration of the different needs of the charging device in both wireless and wired charging scenarios. In the wireless charging scenario, users typically want to be able to use the electronic device 7 normally for activities such as watching videos, making video calls, and reading while charging it. By adjusting the angle of the housing 11 using the stand 6, the placement angle of the electronic device 7 can be adjusted, placing it in a position that is convenient for the user to view and operate, thus achieving the goal of using the device while charging and improving the user experience of wireless charging. For example, by placing the wireless charging pad 1, which is wirelessly charging the electronic device 7, at a suitable angle on the stand 6, the user can comfortably view the content without holding the electronic device 7, freeing their hands and ensuring the stability of the charging process. In the wired charging scenario, the rational use of desktop space is equally important. When traditional charging devices are placed on a desktop, the cables and charging pads are often placed haphazardly, taking up a lot of space. The existence of the stand 6 allows the wireless charging pad 1 to be placed in a more compact and orderly manner, effectively reducing the footprint of the charging device on the desktop. For example, placing the wireless charging stand 1 vertically using the bracket 6 saves significant desktop space compared to laying it flat, making the desktop neater and more organized. This allows users to charge multiple devices and perform tasks like work and study within a limited space. Both the fixed and detachable connection methods are designed around these two core usage scenarios. The fixed connection provides stable support for the bracket 6, ensuring it won't easily wobble or shift when adjusting the wireless charging angle, thus protecting the safety and user experience of the electronic devices 7. The detachable connection enhances the product's flexibility; in wired charging scenarios where the bracket 6 isn't needed, users can detach and store it, reducing unnecessary space occupation and making the charging device more portable and usable in different situations. Furthermore, when the bracket 6 is detached, it can also be used independently to support the electronic devices 7, facilitating video playback and freeing up the hands.

[0073] In one specific embodiment, the bracket 6 is provided with a connecting part 61 and a support part 62 connected to the connecting part 61; the connecting part 61 is fixedly connected to or detachably connected to the housing 11.

[0074] Specifically, the bracket 6 is divided into a connecting part 61 and a supporting part 62. The connecting part 61 is responsible for connecting to the housing 11, and the supporting part 62 is used to place the connecting part 61 on the desktop. This structural design allows the user to flexibly adjust the position and angle of the supporting part 62 according to actual needs when the wireless power supply 1 is wirelessly charging the electronic device 7, thereby changing the placement angle of the connecting part 61, the wireless power supply 1, and the electronic device 7. This makes it convenient for the user to use the electronic device 7 while charging, such as watching videos or making video calls. The supporting part 62 is placed directly on the desktop, providing stable support for the connecting part 61, the wireless power supply 1, and the electronic device 7. Whether it is a fixed connection or a detachable connection, the connection between the bracket 6 and the housing 11 can be guaranteed to be firm, ensuring that the electronic device 7 will not fall off or the charging will be interrupted due to shaking or tilting during use. The design of the bracket 6 also allows the charging device to make better use of desktop space when in use, avoiding the electronic device 7 from occupying too much area when placed flat on the desktop, making the desktop more tidy and orderly.

[0075] Preferably, the stand 6 is designed as a foldable structure. Its core design principle lies in achieving a balance between ease of use and portability of the charging device through its foldable structural characteristics. When unfolded, the stand 6 provides stable support for the wireless power base 1 and the electronic device 7. By adjusting the folding angle, different user needs can be met, such as adjusting the electronic device 7 to a suitable viewing angle for video playback, video calls, and other operations while charging, thus improving the user experience. In storage and carrying scenarios, the foldable stand 6 significantly reduces its own space occupation, making the charging device more compact and convenient for users to place in backpacks, pockets, or other spaces with limited space, meeting users' portability needs in outings and travel. Furthermore, the foldable design of the stand 6 effectively reduces collisions and wear on components during storage, extending the lifespan of the stand 6 and related components. Additionally, when the stand 6 is used alone to support the electronic device 7, the folding angle of the stand 6 can be adjusted as needed.

[0076] More specifically, when the connecting part 61 is fixedly connected to the housing 11, the connecting part 61 and the housing 11 are integrally formed. This integral forming structure eliminates the connection gaps and weak points that may exist in traditional connection methods, ensuring no risk of loosening between the connecting part 61 and the housing 11. During daily use, whether the angle of the bracket 6 is frequently adjusted or subjected to external impact, the bracket 6 and the housing 11 maintain a stable connection, providing reliable support for the electronic device 7 and preventing damage due to unstable connection. This effectively improves the overall durability and safety of the charging device. The integral forming process often represents higher manufacturing precision and quality standards, resulting in a smoother, more aesthetically pleasing product appearance without any splicing marks. This not only enhances the product's visual appeal but also conveys a high-quality product image to users, increasing user recognition and favorability, and helping to improve the product's competitiveness in the market. Compared to other complex fixed connection methods, integral forming reduces assembly steps, reduces errors caused by assembling multiple parts, and improves production efficiency. At the same time, it reduces the number of parts, lowers management costs and quality control difficulties during production, and facilitates large-scale production, reducing product manufacturing costs.

[0077] More specifically, when the connecting part 61 is detachably connected to the housing 11, the detachable connection between the connecting part 61 and the housing 11 is a magnetic connection. The magnetic connection is characterized by its simple operation; the user only needs to bring the connecting part 61 close to the housing 11, and the magnetic force will automatically guide the connecting part 61 to accurately attach into place, eliminating the need for complex installation operations. Disassembly is also quick and easy, requiring only the application of a certain external force. When the stand 6 is needed, the user can quickly complete the installation and easily disassemble it after use, making it particularly suitable for scenarios requiring frequent carrying and use of charging devices, greatly improving usability. When the user does not need to use the stand 6, the detachable magnetic connection allows the user to easily remove the stand 6, reducing the overall size and weight of the charging device and making it easier to carry. For example, when traveling or working, the user can flexibly choose whether to carry the stand 6, making the charging device easier to store in a backpack or pocket, meeting the portability needs of different scenarios. The magnetic connection provides convenient operation while also ensuring a stable connection. During normal use, the magnetic force ensures that the connecting part 61 is tightly connected to the housing 11, and the bracket 6 will not easily fall off even if subjected to slight shaking or external force. Moreover, the magnetic connection does not have the problem of connection failure due to repeated insertion and removal or wear of the clips, ensuring the connection reliability of the product during long-term use.

[0078] See Figure 6As shown, it can be understood that multiple magnets 19 are installed inside the housing 11. One magnet 19 is located near the first storage slot 16 and is used to magnetically attach the input head 3, so as to facilitate the quick and stable storage of the input head 3. Another magnet 19 is located on the wireless power supply module 13 and is used to magnetically attach the electronic device 7, so that when the charging device wirelessly charges the electronic device 7, the electronic device 7 can be quickly and stably connected to the housing 11 and aligned with the wireless power supply module 13 inside the housing 11, thereby achieving the highest charging efficiency and ensuring the stability of wireless charging. There are also two other magnets 19 located near the second storage slot 17 and the bracket 6, respectively, and are used to magnetically attach the third output head 47 and the bracket 6.

[0079] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
