In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a combined mobile charging device, including a power supply body 1 and a charging plug 2. The power supply body 1 can store electrical energy and charge electronic devices such as mobile phones. A first magnetic part 11 and a first conductive part 12 are provided on the power supply body 1. The charging plug 2 is plugged into an external power interface, and can charge the power supply body 1 when connected to the power supply body 1, or directly charge electronic devices such as mobile phones when used alone. The charging plug 2 is provided with a second magnetic part 21 that is adsorbed and connected to the first magnetic part 11 and a second conductive part 22 for electrically connecting to the first conductive part 12. Among them, an opening 3 is provided on the power supply body 1 and / or the charging plug 2, and a shielding part 4 is provided at the opening 3, and the shielding part 4 can movably cover or open the opening 3 as needed. When the opening 3 is open, as Figure 3As shown, the first conductive member 12 and the second conductive member 22 can be connected to each other to realize the combination of the power supply body 1 and the charging plug 2. When the power supply body 1 and the charging plug 2 are separated, as shown in FIG. Figure 4 As shown, the cover 4 can cover the opening 3 .

[0030] Specifically, according to different embodiments, the number and position of the shielding members 4 are different. For example, in some embodiments, Figure 2 and Figure 3 As shown, the opening 3 is only provided on the charging plug 2, with at least a portion of the second conductive member 22 located within the opening 3. The power supply body 1 is inserted into the opening 3, connecting the first conductive member 12 to the second conductive member 22. In this case, the shielding member 4 is connected to the charging plug 2 and conceals the second conductive member 22 within the opening 3 when covering the opening 3. Similarly, in other embodiments, the opening 3 is only provided on the power supply body 1, with at least a portion of the first conductive member 12 located within the opening 3. The charging plug 2 is inserted into the opening 3, connecting the second conductive member 22 to the first conductive member 12. In this case, the shielding member 4 is connected to the power supply body 1 and conceals the first conductive member 12 within the opening 3 when covering the opening 3. In still other embodiments, both the power supply body 1 and the charging plug 2 have openings 3, and two shielding members 4 may be provided, one covering the opening 3 provided on the power supply body 1 and the other covering the opening 3 provided on the charging plug 2.

[0031] Specifically, the first magnetic part 11 and the second magnetic part 21 are magnetic connection structures for reinforcing the electrical connection between the first conductive part 12 and the second conductive part 22. The magnetic connection has the advantages of simple structure, convenient connection and disassembly operations, and no need for direct contact. Optionally, in some embodiments, the first magnetic part 11 is a magnet, and the second magnetic part 21 is a ferromagnetic metal part such as an iron sheet or a cobalt sheet; in other embodiments, the first magnetic part 11 is a ferromagnetic metal part such as an iron sheet or a cobalt sheet, and the second magnetic part 21 is a magnet; in yet other embodiments, the first magnetic part 11 and the second magnetic part 21 are both magnets. The above embodiments can be flexibly selected as long as the adsorption connection between the first magnetic part 11 and the second magnetic part 21 can be achieved.

[0032] Optionally, the shielding member 4 can be in the form of a cover, protective sleeve, or housing, as long as it provides effective covering and protection for the connection structure. Alternatively, to achieve a movable connection of the shielding member 4, for example, the cover can be in the form of a flip-up cover that rotates about a rotation axis, a sliding cover that slides along a guide rail, or a detachable connection, as long as the shielding member 4 can be controlled to switch between covering and opening the opening 3 as needed. Therefore, it can be understood that the shielding member 4 has a high degree of design flexibility.

[0033] For the sake of convenience, taking the opening 3 as an example, when the power supply body 1 is separated from the charging plug 2, the Figure 4 As shown, the shielding member 4 covers the opening 3 and the second conductive member 22, making it difficult to see from the outside that the second conductive member 22 is provided on the charging plug 2. The shielding member 4 and the outer shell of the charging plug 2 form a relatively complete and symmetrical geometric shape, thereby improving the aesthetics. In addition, the shielding member 4 can also separate the second conductive member 22 from the external environment, effectively preventing external debris from contacting the second conductive member 22, and providing good isolation and protection. When the power supply body 1 and the charging plug 2 need to be combined, as shown in FIG. Figure 3 As shown, since the shielding member 4 is movable, the user can operate the shielding member 4 to open the opening 3, so that the second conductive member 22 is exposed and connected to the first conductive member 12. At the same time, the first magnetic member 11 is close to the second magnetic member 21 for adsorption connection, thereby completing the combination of the power supply body 1 and the charging plug 2, which is easy to use and operate.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, to enhance the adsorption force between the first magnetic member 11 and the second magnetic member 21 and improve the fixing effect, at least a portion of the second magnetic member 21 can be positioned within the opening 3. In this design, the second magnetic member 21 is not blocked by the outer shell of the charging plug 2, which can reduce the distance between the second magnetic member 21 and the first magnetic member 11 during adsorption, thereby enhancing the adsorption force. In addition, with this design, the shielding member 4 can also cover the second magnetic member 21, improving the aesthetics.

[0035] The combined mobile charging device provided in an embodiment of the present invention includes a power supply body 1 and a charging plug 2. The power supply body 1 is provided with a first magnetic member 11 and a first conductive member 12, and the charging plug 2 is provided with a second magnetic member 21 and a second conductive member 22. The first magnetic member 11 is attracted to the second magnetic member 21, and the first conductive member 12 and the second conductive member 22 are electrically connected, thereby achieving a detachable connection between the power supply body 1 and the charging plug 2. This allows the power supply body 1 and the charging plug 2 to be used together or separately. Due to the magnetic connection, the connection and detachment operations are simple. In addition, the embodiment of the present invention adopts an opening 3 formed in the power supply body 1 and / or the charging plug 2, concealing the conductive member within the opening 3. A shielding member 4 is provided at the opening 3 for movable covering or opening the opening 3. The shielding member 4 covers the opening 3 and the conductive member within the opening 3. When covering the opening 3, the shielding member 4 and the outer shell of the power supply body 1 and / or the outer shell of the charging plug 2 form a relatively complete and symmetrical appearance, effectively improving the aesthetics. At the same time, the shielding member 4 can also provide good isolation protection for the shielded conductive member, effectively preventing the conductive member from colliding, rubbing and other problems with external objects. The conductive member is not easily damaged, has good reliability in long-term use, and extends its service life.

[0036] In some embodiments, such as Figure 2 As shown, the shielding member 4 includes a baffle 41 and an elastic member 42 . The baffle 41 is used to movably cover or open the opening 3 . The elastic member 42 is at least connected to the baffle 41 to drive the baffle 41 to automatically cover the opening 3 .

[0037] For example, in some embodiments, Figure 2 and Figure 3 As shown, the opening 3 is formed on the charging plug 2, and the movement of the baffle 41 relative to the opening 3 can be set to be telescopic movement along the direction of the opening 3. The elastic member 42 can be connected between the housing of the charging plug 2 and the baffle 41, and apply a force toward the opening 3 to the baffle 41 to drive the baffle 41 to telescopic movement along the opening direction of the opening 3. When the baffle 41 is not subjected to external force, the elastic member 42 can push the baffle 41 to move to a position covering the opening 3, so that the baffle 41 automatically covers the opening 3. In some embodiments, such as Figure 2As shown, the baffle 41 can be provided with a through hole for the second conductive member 22 to pass through. When the opening 3 needs to be opened, the user can push the baffle 41 into the opening 3, so that the second conductive member 22 passes through the baffle 41 and is exposed. At this time, the second conductive member 22 can be electrically connected to the first conductive member 12, so that the power supply body 1 is connected to the charging plug 2. When designed in this way, the baffle 41 opens the opening 3 by retracting into the opening 3. Therefore, no additional external space is required when opening the opening 3, which is a clever design. It should be noted that in order to achieve a reliable connection between the power supply body 1 and the charging plug 2, the force applied by the elastic member 42 to push the baffle 41 to cover the opening 3 is smaller than the adsorption force between the first magnetic member 11 and the second magnetic member 21.

[0038] For example, in some embodiments, the baffle 41 can also be set as a flip-up form that rotates around the rotating shaft, and the elastic member 42 can be a torsion spring structure set on the rotating shaft. When the baffle 41 is not subjected to external force, the baffle 41 is driven to rotate by the torsion spring, thereby realizing automatic covering of the opening 3.

[0039] By adopting the above design, when the power supply body 1 is separated from the charging plug 2, the baffle 41 can automatically reset the covering opening 3 under the drive of the elastic member 42, without the need for manual operation, making it more convenient to use and further improving the user experience.

[0040] In some embodiments, the cross-sectional shape of the elastic member 42 is "racetrack-shaped" or "elliptical" along the direction perpendicular to the direction in which the elastic member 42 drives the baffle 41 to move. For example, in some embodiments, as Figure 2 and Figure 3 As shown, the opening 3 is opened on the charging plug 2, and the elastic member 42 is provided between the housing of the charging plug 2 and the baffle 41 to drive the baffle 41 to move in the direction of opening 3. At this time, the baffle 41 moves in a direction perpendicular to the direction in which the elastic member 42 drives the baffle 41 to move. Figure 5 As shown, the cross-section of the elastic member 42 is a "racetrack" shape, i.e., a combination of a semicircle and straight line segments. In other embodiments, the cross-section of the elastic member 42 can also be an "elliptical" shape. This design provides a larger contact area between the elastic member 42 and the baffle 41 than a conventional cylindrical spring. When the elastic member 42 applies force to the baffle 41, the force is more evenly applied to the baffle 41, resulting in better stability.

[0041] In some embodiments, such as Figures 4 to 6 As shown, a slot 23 is provided on the portion of the housing of the charging plug 2 located in the opening 3, and the elastic member 42 is locked in the slot 23. For example, in some embodiments, as Figure 4As shown, the shape of the card slot 23 in the figure is an inverted "T" shape, forming a structure that is narrow at the top and wide at the bottom. In this way, one end of the elastic member 42 can be restricted to the wider part at the bottom, making it difficult to loosen. When installing the elastic member 42, the installation can be completed by simply squeezing the elastic member 42 into the card slot 23. No tools are required for installation, and no bonding, welding, or other methods are required for installation. The installation operation is relatively convenient. In some embodiments, such as Figure 6 As shown, the housing of the charging plug 2 can be formed by splicing two halves, and the slot 23 is provided on one half of the housing and extends toward one side to penetrate the side wall of the housing. In this design, the elastic member 42 only needs to slide into the slot 23 from the side through which the slot 23 extends, and then the two halves of the housing are spliced ​​into a complete housing to complete the installation of the elastic member 42. The above installation operation is more convenient.

[0042] In some embodiments, such as Figure 5 and Figure 6 As shown, a limiting protrusion 24 for limiting the elastic member 42 is provided in the slot 23, and the limiting protrusion 24 abuts against the elastic member 42 along a direction perpendicular to the direction in which the elastic member 42 drives the baffle 41 to move. For example, in some embodiments, as Figure 5 As shown, the housing of the charging plug 2 is made up of two halves, and both halves of the housing are provided with limiting protrusions 24. When the elastic member 42 is installed in the slot 23, the limiting protrusions 24 provided on the two halves of the housing abut against the elastic member 42 in opposite directions, thereby effectively preventing the elastic member 42 from loosening in the slot 23 and improving the stability of the elastic member 42. Figure 5 The perspective shown is for reference only. The position where the limiting protrusion 24 is set can be on the upper and lower sides relative to the elastic member 42, or on the left and right sides, etc., as long as it can abut against the elastic member 42 to limit the position of the elastic member 42 in the slot 23, it can have the effect of improving the stability of the elastic member 42.

[0043] In some embodiments, such as Figure 3 and Figure 4 As shown, the shielding member 4 further includes a first limiting structure 43 provided on the baffle 41 and a second limiting structure 44 provided on the housing of the charging plug 2 . The first limiting structure 43 is connected to the second limiting structure 44 to limit the baffle 41 to be flush with the opening 3 .

[0044] Specifically, the first limiting structure 43 and the second limiting structure 44 are mutually adapted connection structures. When the first limiting structure 43 and the second limiting structure 44 are connected, the baffle 41 can be limited to a preset position, i.e., a position flush with the opening 3. For example, in some designs, the first limiting structure 43 is configured as a buckle, and the second limiting structure 44 is configured as a snap-fit ​​hole. When the first limiting structure 43 and the second limiting structure 44 are connected by snap-fit, the baffle 41 is exactly flush with the opening 3, and under the restraining effect of the snap-fit ​​between the first limiting structure 43 and the second limiting structure 44, the baffle 41 cannot extend outward from the opening 3. In other designs, the first limiting structure 43 and the second limiting structure 44 can be configured as mutually abutting step structures. When the baffle 41 is flush with the opening 3, they abut against each other to prevent the baffle 41 from extending outward from the opening 3. Optionally, the first limiting structure 43 and the baffle 41 can be integrally formed, or they can be separately provided and connected to each other; similarly, the second limiting structure 44 can be integrally formed with the housing of the charging plug 2, or it can be an independent component installed on the housing of the charging plug 2.

[0045] The above embodiment uses a first limiting structure 43 connected to a second limiting structure 44 to limit the baffle 41 to a position flush with the opening 3. The baffle 41 will not extend outward without external force, and the structure has better flatness and better aesthetics. In addition, the baffle 41 can fully cover the opening 3, thereby having a better isolation and protection effect.

[0046] In some embodiments, such as Figures 4 to 6 As shown, the first limiting structure 43 includes a guide member 431 and a limiting member 432. The guide member 431 is connected to the baffle 41 to guide its movement. The limiting member 432 is connected to the guide member 431 to abut against the second limiting structure 44 for limiting its position. The housing of the charging plug 2 is provided with a guide space 25 for the guide member 431 to move through. This design not only ensures that the baffle 41 is flush with the opening 3 but also provides guidance for the baffle 41, ensuring smoother movement.

[0047] In some embodiments, such as Figures 3 to 6 As shown, the opening 3 is defined on the charging plug 2, with the second conductive member 22 positioned centrally within the opening 3. Furthermore, at least two of the second magnetic member 21, elastic member 42, retaining slot 23, retaining protrusion 24, first retaining structure 43, and second retaining structure 44 are symmetrically positioned relative to the second conductive member 22. This arrangement creates a symmetrical and aesthetically pleasing overall structure for the charging plug 2, ensuring reliable connection to the power bank. Furthermore, the baffle 41 experiences balanced forces when it extends and retracts relative to the opening 3.

[0048] The embodiment of the present utility model also provides a power supply body 1, which can be connected and used in combination with a charging plug 2 provided with a second magnetic part 21 and a second conductive part 22. When used alone, the power supply body 1 can charge mobile electronic products such as mobile phones through the stored electrical energy. The power supply body 1 includes a first magnetic part 11 and a first conductive part 12. The first magnetic part 11 is used to be adsorbed and connected with the second magnetic part 21, and the first conductive part 12 is used to be electrically connected with the second conductive part 22. The power supply body 1 is also provided with an opening 3 for the charging plug 2 to be inserted and connected. At least a portion of the first conductive part 12 is located in the opening 3, and a shielding part 4 is provided at the opening 3 for movably covering or opening the opening 3. It can be understood that the specific implementation of the shielding part 4 is described in detail in the above embodiment using the charging plug 2 as an example. Its design concept can also be applied to the power supply body 1, and will not be repeated here. The power supply body 1 provided in the embodiment of the present invention has good aesthetics by using a shielding member 4 to cover the opening 3 and the first conductive member 12 in the opening 3. The shielding member 4 provides good isolation and protection, making the first conductive member 12 less susceptible to damage and having good reliability for long-term use.

[0049] The present embodiment also provides a charging plug 2. The charging plug 2 can be used in combination with a power supply body 1 equipped with a first magnetic member 11 and a first conductive member 12. When used alone, the charging plug 2 can be plugged into an external power source to charge electronic devices such as mobile phones. The charging plug 2 includes a second magnetic member 21 and a second conductive member 22. The second magnetic member 21 is configured to attach to the first magnetic member 11, and the second conductive member 22 is configured to electrically connect to the first conductive member 12. The charging plug 2 defines an opening 3 for insertion and connection of the power supply body 1. At least a portion of the second conductive member 22 is positioned within the opening 3. A shield 4 is provided at the opening 3 for removably covering or opening the opening 3. It is understood that the specific implementation of the shield 4 is described in detail in the above-mentioned embodiment and will not be further elaborated here. Similar to the power supply body 1 described above, the charging plug 2 provided in the present embodiment utilizes a shield 4 to cover and protect the opening 3 and the second conductive member 22 within the opening 3, resulting in improved aesthetics and reliability.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
