[0037] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0038] Each specific technical feature described in the specific embodiments can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of each specific technical feature in the present utility model will not be described separately.

[0039] In the following description, the terms "first / second / ..." involved are only used to distinguish different objects and do not indicate that there are the same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", and "inside" involved are all in the orientation in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which may or may not be the left and right directions in the normal use state.

[0040] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including that element. "Plurality" means greater than or equal to two.

[0041] As Figures 1 to 3 shown, an embodiment of the present utility model provides a combined mobile charging device, including a power supply body 1, a charging plug 2 and a shielding member 3. The power supply body 1 can be used to charge a device to be charged, and a first connection structure 11 is provided on the power supply body 1. A second connection structure 21 detachably connected to the first connection structure 11 is provided on the charging plug 2, that is, the first connection structure 11 and the second connection structure 21 are structures that can cooperate with each other. When the charging plug 2 is connected to the power supply body 1, it can be used to charge the power supply body 1, and when used alone, it can directly charge electronic devices such as mobile phones. According to different design schemes, the shielding member 3 can be movably connected to the power supply body 1 to cover or expose the first connection structure 11; it can also be movably connected to the charging plug 2 to cover or expose the second connection structure 21; it can also be movably connected to the power supply body 1 and the charging plug 2 respectively to cover or expose the first connection structure 11 and the second connection structure 21 respectively.

[0042] Specifically, the first connection structure 11 and the second connection structure 21 are structures that are mutually adapted and capable of achieving detachable connection. Generally, one or more of the following schemes can be adopted, such as snap connection, magnetic attraction connection, clamping connection, Velcro bonding, etc., as long as a reliable connection between the power supply body 1 and the charging plug 2 can be achieved and they can be detached and separated at any time as needed.

[0043] Specifically, the position and quantity of the shielding member 3 can be designed by comprehensively considering factors such as the influence of the connection structure on the aesthetics, the vulnerability of the connection structure, and the production cost. For example, when the first connection structure 11 is more likely to affect the aesthetics or is more vulnerable than the second connection structure 21, the shielding member 3 can be provided only on the power supply body 1 to cover and protect the first connection structure 11. Generally, an outwardly protruding connection structure is more likely to affect the aesthetics of the product and is also more likely to collide, scrape, and rub against external objects. At this time, it can be considered to provide the shielding member 3 at the position corresponding to the outwardly protruding connection structure. Of course, the shielding member 3 can also be provided at the position corresponding to the inwardly concave connection structure to prevent external objects from extending into the connection structure and causing damage, and also to prevent dust and other impurities from entering the connection structure, resulting in problems such as dirt accumulation and difficulty in cleaning. Optionally, the specific form of the shielding member 3 can generally be determined according to the connection structure that needs to be covered and protected. For example, the shielding member 3 can be in various forms such as a cover plate, a protective sleeve, a housing, etc., as long as it can provide effective covering and protection for the connection structure. Optionally, to achieve the movable connection of the shielding member 3, taking the cover plate as an example, it can adopt a flip form that rotates around a rotating shaft, a sliding cover form that slides along a guide rail, or a detachable connection form, etc., as long as it can control the shielding member 3 to switch between the covering state and the exposed state as needed. Therefore, it can be understood that the shielding member 3 has a high degree of design flexibility.

[0044] Specifically, taking the shielding member 3 provided on the power supply body 1 as an example, as Figure 2 and Figure 3 shown, when the power supply body 1 is separated from the charging plug 2, since the shielding member 3 covers the first connection structure 11, it is difficult to see from the outside that the first connection structure 11 is provided on the power supply body 1. And when the shielding member 3 covers the first connection structure 11, it can form a relatively complete and symmetrical geometric shape with the power supply body 1, thus effectively improving the aesthetics. At the same time, the shielding member 3 can also separate the first connection structure 11 from the external environment, preferably avoiding external sundries from contacting the first connection structure 11 and providing a good isolation and protection effect. When it is necessary to combine the power supply body 1 and the charging plug 2, since the shielding member 3 is movable, the user can operate the shielding member 3 to expose the first connection structure 11 and connect it to the second connection structure 21, thereby completing the combination of the power supply body 1 and the charging plug 2, and the use operation is simple.

[0045] The modular mobile charging device provided by the embodiment of the present utility model includes a power supply body 1, a charging plug 2, and a shielding member 3. A first connection structure 11 is provided on the power supply body 1, and a second connection structure 21 is provided on the charging plug 2. The first connection structure 11 and the second connection structure 21 are detachably connected to achieve the detachable connection between the power supply body 1 and the charging plug 2, so that the power supply body 1 and the charging plug 2 can be used either in combination or separately. At the same time, in the embodiment of the present utility model, the shielding member 3 is used to cover the first connection structure 11 and / or the second connection structure 21, effectively reducing the adverse impact on the aesthetics caused by the connection structure being exposed to the environment. Moreover, the shielding member 3 can also provide good isolation protection for the connection structure being shielded, effectively preventing problems such as collision and friction between the connection structure and external objects, making the connection structure not easily damaged and having better reliability during long-term use.

[0046] In some embodiments, the connection mode between the first connection structure 11 and the second connection structure 21 adopts snap connection, that is, one of the first connection structure 11 and the second connection structure 21 is a snap, and the other is a snap groove, and the snap and the snap groove are snap-connected to each other. In other embodiments, the connection mode between the first connection structure 11 and the second connection structure 21 adopts magnetic attraction connection, that is, the first connection structure 11 is a first magnetic member, the second connection structure 21 is a second magnetic member, and the first magnetic member and the second magnetic member are magnetically attracted to each other. Of course, any one of the first connection structure 11 and the second connection structure 21 can be a magnetic member, and the other is a metal member that can be attracted to the magnetic member. The snap connection and magnetic attraction connection adopted in the above implementation schemes can both achieve the detachable connection between the first connection structure 11 and the second connection structure 21, and have simple structures and are easy to implement, with convenient disassembly and assembly operations and good user experience.

[0047] In some embodiments, as Figure 2 and Figure 3 shown, one of the first connection structure 11 and the second connection structure 21 is a snap groove 211, and the other includes a receiving shell 111 and a snap 112 disposed in the receiving shell 111 for snap-connecting with the snap groove 211. The receiving shell 111 has an opening 1111, and the shielding member 3 is at least used to movably cover or open the opening 1111.

[0048] For the sake of convenience of description, take as an example that the first connection structure 11 includes a receiving shell 111 and a buckle 112, and the second connection structure 21 is a clamping groove 211. Among them, the receiving shell 111 can be directly formed by dividing a part of the structure of the power supply body 1, or can be separately arranged from the power supply body 1 and connected to the power supply body 1. When the power supply body 1 is connected to the charging plug 2, the shielding member 3 can be controlled to open the opening 1111, and the charging plug 2 can be inserted into the receiving shell 111, so that the clamping groove 211 cooperates with the buckle 112 for clamping, thereby forming a combined mobile charging device as shown in Figure 1 . When the power supply body 1 is separated from the charging plug 2, the shielding member 3 covers the opening 1111. At this time, the buckle 112 is hidden inside the receiving shell 111, and it is difficult to see the structure of the buckle 112 from the outside, so it has better aesthetics. At the same time, the shielding member 3 can better prevent external substances such as dust from entering the receiving shell 111 through the opening 1111, and separate the buckle 112 from the external environment, thereby providing a good protection effect.

[0049] It can be understood that the specific implementation schemes of the first connection structure 11 and the second connection structure 21 in the above example can be interchanged. In other words, the first connection structure 11 can be set as a clamping groove, and the second connection structure 21 includes a receiving shell and a buckle. Such a design can also achieve the same effect as the above example.

[0050] In some embodiments, as shown in Figure 3 , the shielding member 3 includes a baffle 31 and an elastic member 32. The baffle 31 is used to movably cover or open the opening 1111, and the elastic member 32 is connected between the inner wall of the receiving shell 111 and the baffle 31. The elastic member 32 is used to drive the baffle 31 to automatically cover the opening 1111. Specifically, the movement of the baffle 31 relative to the opening 1111 can be set as telescopic movement along the orientation of the opening 1111. The elastic member 32 can be connected to the inner wall of the receiving shell 111 opposite to the opening 1111 and apply a force towards the opening 1111 direction to the baffle 31, so as to push the baffle 31 to move to the position covering the opening 1111, so that the baffle 31 keeps covering the opening 1111 when not affected by external forces. When it is necessary to open the opening 1111, as shown in Figure 4 , the user can push the baffle 31 into the receiving shell 111 until the buckle 112 is exposed. At this time, the buckle 112 can be clamped with the clamping groove 211 (refer to Figure 2 ), so that the power supply body 1 is connected to the charging plug 2 (refer to Figure 2 ). By adopting the above design, when the power supply body 1 is separated from the charging plug 2, the baffle 31 can be automatically reset to cover the opening 1111 under the drive of the elastic member 32 without manual operation, which is more convenient to use and further improves the use experience.

[0051] In some embodiments, as shown inFigure 3 As shown, the shielding member 3 further includes a first limiting structure 33 provided on the baffle 31 and a second limiting structure 34 provided on the accommodation shell 111. The first limiting structure 33 is connected to the second limiting structure 34 to limit the baffle 31 to be flush with the opening 1111. Specifically, the first limiting structure 33 and the second limiting structure 34 are mutually adapted connection structures. When the first limiting structure 33 is connected to the second limiting structure 34, the baffle 31 can be limited to a preset position, that is, the position flush with the opening 1111. In some design schemes, the first limiting structure 33 is set as a buckle, and the second limiting structure 34 is set as a clamping hole or a clamping groove. The first limiting structure 33 and the second limiting structure 34 are connected by a clamping method, and the connection state is as Figure 5 shown. At this time, the baffle 31 is exactly flush with the opening 1111, and under the limiting action of the clamping connection between the first limiting structure 33 and the second limiting structure 34, the baffle 31 cannot protrude outward from the opening 1111.

[0052] Optionally, the first limiting structure 33 and the second limiting structure 34 can also adopt other design schemes. For example, in some design schemes, as Figure 6 shown, the first limiting structure 33 and the second limiting structure 34 are set as stepped structures that abut against each other; for another example, in some other design schemes, as Figure 7 shown, the first limiting structure 33 is a limiting hole opened on the baffle 31, and the buckle 112 is used as the second limiting structure 34. The limiting effect is achieved by snapping the buckle 112 into the limiting hole. The above design schemes can be selected as needed, or other feasible design schemes can be adopted, as long as the baffle 31 can be limited to the position flush with the opening 1111.

[0053] In the above embodiment, by connecting the first limiting structure 33 and the second limiting structure 34, the baffle 31 is limited to the position flush with the opening 1111. The baffle 31 will not protrude outward without external force, the structural flatness is better, and it has better aesthetics. Moreover, the baffle 31 can fully cover the opening 1111, so it has a better isolation and protection effect.

[0054] In some embodiments, as Figure 8 shown, along the opening 1111 (refer to Figure 3)In the direction of orientation, chamfers are provided on both sides of the buckle 112, and / or chamfers are provided on both side edges of the clamping groove 211. By providing chamfers on both sides of the buckle 112 and / or the clamping groove 211, when the charging plug 2 is connected to or separated from the power supply body 1, both the buckle 112 and the clamping groove 211 can slide along the inclined surface of the chamfer, making it more labor-saving during connection or separation. Moreover, the design of the chamfer can reduce the collision and wear of sharp edges, thereby further improving the durability. It can be understood that when chamfers are provided only on both sides of the buckle 112 or the clamping groove 211, compared with the design without chamfers, it can also make it more labor-saving when the buckle 112 and the clamping groove 211 are connected or separated, and reduce the problem of sharp edge collision and wear, improving the durability to a certain extent. When chamfers are provided on both sides of the buckle 112 and the clamping groove 211 respectively, the shape matching degree of the buckle 112 and the clamping groove 211 is higher, and it has a more excellent effect compared with providing chamfers only on the buckle 112 or the clamping groove 211. Optionally, no more specific limitations are imposed on the specific angle of the chamfer, and it is specifically based on meeting the usage requirements. As an example, in some embodiments, the angle range of the chamfer is set to 40° to 50°; in some embodiments, the angle of the chamfer is set to 45°, and this design usually has a better effect of reducing collision and wear and is easier to manufacture.

[0055] In some embodiments, a rotating shaft 113 is provided between the accommodating shell 111 and the buckle 112, and the buckle 112 rotates relative to the accommodating shell 111 through the rotating shaft 113 to be clamped with or separated from the clamping groove 211. In the above design, only by controlling the rotation of the buckle 112 can the connection or separation with the clamping groove 211 be achieved. To realize the control of the rotation of the buckle 112, in some embodiments, the buckle 112 is fixed to the rotating shaft 113, and at the same time, the rotating shaft 113 passes through the side wall of the accommodating shell 111 and extends to the outside, and a knob is connected outside the accommodating shell 111. In this design, the rotating shaft 113 and the buckle 112 can be driven to rotate by rotating the knob, so that the buckle 112 can be clamped with or separated from the clamping groove 211 as needed.

[0056] In some other embodiments, as Figure 8 and Figure 9 shown, the buckle 112 includes a clamping head 1121 for being clamped into the clamping groove 211 and a butting head 1122 for butting and driving. The rotating shaft 113 is arranged between the clamping head 1121 and the butting head 1122. A pushing piece 311 is provided on the baffle 31 at the position corresponding to the buckle 112. The structure of the pushing piece 311 can also refer to Figure 3As shown, the pushing piece 311 is used to push against the abutting joint 1122 to drive the clamping joint 1121 to rotate and snap into the clamping groove 211. Specifically, when the charging plug 2 is connected to the power supply body 1, the pushing piece 311 moves towards the inside of the receiving shell 111 along with the baffle 31 until it abuts against the abutting joint 1122. At this time, the pushing piece 311 continues to move and squeeze the abutting joint 1122, causing the abutting joint 1122 and the clamping joint 1121 to rotate synchronously around the rotating shaft 113, so that the clamping joint 1121 moves towards the direction close to the clamping groove 211 and snaps into the clamping groove 211 to complete the connection. With this design, as long as the charging plug 2 is inserted into the receiving shell 111, the clamping joint 1121 of the buckle 112 can be automatically snapped into the clamping groove 211 by the pushing piece 311, without the need to control the rotation of the buckle 112 through additional operations, making the operation more convenient and further improving the user experience.

[0057] In some embodiments, as Figure 10 shown, a damping member 114 for increasing the rotational resistance is provided on the rotating shaft 113. The damping member 114 can be made of materials such as rubber and plastic, and the damping member 114 has the effect of increasing the rotational resistance through the characteristics of the material itself. With this design, when the buckle 112 rotates, since the damping member 114 increases the rotational resistance, the rotational stability of the buckle 112 can be improved, facilitating the control of the rotational amplitude of the buckle 112, effectively preventing the buckle 112 from being too loose and rotating greatly or quickly, and thus better avoiding problems such as abnormal noises or wear caused by the violent collision of the buckle 112 with the surrounding structure when it rotates.

[0058] In some embodiments, a torsion spring for applying rotational resistance is sleeved on the rotating shaft 113. With this design, the buckle 112 can be better maintained in the clamped state with the clamping groove 211 through the acting force applied by the torsion spring, thereby further improving the connection stability.

[0059] The embodiment of the present utility model also provides a power supply body 1 for connecting with a charging plug 2 provided with a second connection structure 21. The power supply body 1 can store electric energy and can be used to charge mobile electronic products such as mobile phones, smart watches, and tablet computers. The power supply body 1 includes a first connection structure 11 and a shielding member 3. The first connection structure 11 is used for detachably connecting with the second connection structure 21. The shielding member 3 is movably connected to the power supply body 1 to cover or expose the first connection structure 11. For example, in some embodiments, the second connection structure 21 is a clamping groove 211, and the first connection structure 11 includes a receiving shell 111 and a buckle 112 arranged in the receiving shell 111 for clamping with the clamping groove 211. The receiving shell 111 has an opening 1111, and the shielding member 3 is at least used to movably cover or open the opening 1111. For the power supply body 1 provided by the embodiment of the present utility model, by using the shielding member 3 to cover the first connection structure 11, it has better aesthetics, and the shielding member 3 provides a good isolation and protection effect, making the first connection structure 11 not easily damaged and having good reliability in long-term use. For the specific structures of the first connection structure 11 and the shielding member 3, detailed descriptions have been made in the above embodiments and will not be elaborated here.

[0060] The embodiment of the present utility model also provides a charging plug 2 for connecting with the power supply body 1 provided with the first connection structure 11. The charging plug 2 includes a second connection structure 21 and a shielding member 3. The second connection structure 21 is used for detachably connecting with the first connection structure 11. The shielding member 3 is movably connected to the charging plug 2 to movably cover or expose the second connection structure 21. For example, in some embodiments, the first connection structure 11 is a clamping groove 211, and the second connection structure 21 includes a receiving shell 111 and a buckle 112 arranged in the receiving shell 111 for clamping with the clamping groove 211. The receiving shell 111 has an opening 1111, and the shielding member 3 is at least used to movably cover or open the opening 1111. The charging plug 2 provided by the embodiment of the present utility model is the same as the above-mentioned power supply body 1.
