[0038] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present utility model will be described in detail.

[0039] The embodiment of the present utility model provides a mobile power supply 1000, as Figures 1-5As shown, the mobile power supply 1000 includes a housing 100, a charging cable 200 and a hard cover 300. The housing 100 has a receiving cavity 110, and a first opening 111 and a second opening 112 are provided on the cavity wall of the receiving cavity 110. The housing 100 is provided with a first buckle structure 400. The charging cable 200 includes a charging head group 210 and a line body 220. The charging head group 210 includes two charging heads 211 respectively installed on both sides of the line body 220. The charging head group 210 is installed in the receiving cavity 110 through the first opening 111, and the outline of the charging head group 210 is larger than the outline of the second opening 112, so that the charging head group 210 cannot be separated from the receiving cavity 110 through the second opening 112. The charging cable 200 is inserted into the second opening 112, and the user can use the charging cable 200 to hang the mobile power supply 1000. The hard cover plate 300 is provided with a second buckle structure 310 , and the second buckle structure 310 is used to cooperate with the first buckle structure 400 so that the hard cover plate 300 can be movably buckled at the second opening 112 to cover or expose the first opening 111 .

[0040] By implementing this embodiment, the hard cover 300 can be used to cover or expose the first opening 111. When the charging cable 200 needs to be used, the first opening 111 is exposed so that the charging head group 210 can be separated from the accommodating cavity 110 through the first opening 111. When the charging cable 200 is stored, the charging head group 210 is inserted into the accommodating cavity 110 through the first opening 111, and then the first snap structure 400 and the second snap structure 310 are used to buckle the hard cover 300 at the first opening 111. At this time, the hard cover 300 will restrict the charging head group 210 from being separated from the accommodating cavity 110.

[0041] Specifically, the prior art uses a soft rubber plug at the first opening 111 to limit the charging head group 210 from detaching from the first opening 111. As the service life increases, the soft rubber plug will become looser and easier to detach from the first opening 111. At this time, the risk of losing the charging cable 200 will increase. In contrast, in this embodiment, a hard cover plate 300 is buckled and installed at the first opening 111 to limit the charging head group 210 from detaching from the first opening 111. Even if the service life is relatively long, it can still be relatively firmly blocked at the first opening 111 to limit the charging head group 210 from detaching from the first opening 111, thereby avoiding the loss of the charging cable 200.

[0042] refer to Figure 5 In a specific embodiment, the mobile power supply 1000 further includes a rotating shaft 500, which is connected to a side of the hard cover plate 300 away from the second snap structure 310, and the rotating shaft 500 is also connected to the shell 100 so that the hard cover plate 300 is rotatably connected to the shell 100.

[0043] With such a setting, after the first buckle structure 400 is disconnected from the second buckle structure 310, the hard cover plate 300 can still be connected to the housing 100 through the rotating shaft 500. This is not only convenient for the user to cover the hard cover plate 300 again, but also not likely to cause the loss of the hard cover plate 300, killing two birds with one stone.

[0044] In another specific embodiment, the housing 100 and the hard cover plate 300 are only connected through the first buckle structure 400 and the second buckle structure 310. After the first buckle structure 400 and the second buckle structure 310 are disengaged from the buckling relationship, the housing 100 and the hard cover plate 300 are completely separated. Exemplarily, both the first buckle structure 400 and the second buckle structure 310 are provided with a plurality of them. The plurality of second buckle structures 310 are arranged at different positions of the hard cover plate 300. The plurality of first buckle structures 400 cooperate with the plurality of second buckle structures 310 to buckle the hard cover plate 300 at the first opening 111. After the plurality of first buckle structures 400 and the plurality of second buckle structures 310 are disengaged from the buckling relationship, the hard cover plate 300 and the housing 100 are completely separated.

[0045] Reference Figure 3 As shown in, in some embodiments, the mobile power supply 1000 further includes a button 600. The button 600 is movably mounted on the housing 100 in the first direction ( Figure 2 the X direction shown). The first buckle structure 400 is connected to the button 600, and the first buckle structure 400 is located in the first direction of the accommodation cavity 110. In the first direction, the first buckle structure 400 and the second buckle structure 310 are oppositely arranged, and the second buckle structure 310 is located on the side of the first buckle structure 400 facing away from the accommodation cavity 110, so that the first buckle structure 400 can be hooked with the second buckle structure 310.

[0046] Specifically, after the user presses the button 600, it will drive the first buckle structure 400 to move in the direction close to the accommodation cavity 110. Since the first buckle structure 400 and the second buckle structure 310 are oppositely arranged, and the second buckle structure 310 is located on the side of the first buckle structure 400 away from the accommodation cavity, when the user presses the button 600, the first buckle structure 400 will simultaneously move in the direction away from the second buckle structure 310, so that the first buckle structure 400 can move to be separated from the second buckle structure 310. At this time, as long as the hard cover plate 300 is rotated, the first opening 111 can be exposed.

[0047] It should be noted that either one of the first buckle structure 400 and the second buckle structure 310 can be a hook, and the other can be a slot, or both can be hooks, as long as the first buckle structure 400 and the second buckle structure 310 can be hooked with each other so that the hard cover plate 300 can be buckled at the first opening 111. This embodiment does not make any limitations here.

[0048] Reference Figure 3 、 Figure 6 、 Figure 7 In a specific embodiment, a first mounting groove 120 is provided on the housing 100 along a first direction. The button 600 is mounted in the first mounting groove 120. A compression spring 700 is clamped between the button 600 and the bottom 121 of the first mounting groove 120. A second mounting groove 130 is provided on one side of the first buckle close to the button 600. The second mounting groove 130 communicates with the first mounting groove 120. The second buckle structure 310 is mounted at the second mounting groove 130.

[0049] By implementing this embodiment, the button 600 can be automatically reset after use. Specifically, a compression spring 700 is provided between the button 600 and the bottom 121 of the first mounting groove 120 in this embodiment. In this way, when the user presses the button 600, the compression spring 700 can be compressed to store energy. After the user stops pressing the button 600, the compression spring 700 will deform and release energy, thereby driving the button 600 to reset.

[0050] Reference Figure 3 In a specific embodiment, the button 600 and the first buckle structure 400 are integrally formed.

[0051] Specifically, although the button 600 and the first buckle structure 400 can be separately formed and connected together by assembly, since the button 600 needs to drive the first buckle structure 400 to move, after being impacted by an external force and used for a long time, the assembly may become loose, which may cause the first buckle structure 400 to not cooperate well with the second buckle structure 310. Therefore, the button 600 and the first buckle structure 400 in this embodiment are integrally formed.

[0052] Furthermore, since the button 600 and the first buckle structure 400 are integrally formed, the size of the first mounting groove 120 cannot be designed too small, otherwise the button 600 and the first buckle structure 400 cannot be placed into it. To ensure that the button 600 can be placed into the first mounting groove 120, the size of the first mounting groove 120 needs to be designed relatively large, which also causes the gap between the groove wall of the first mounting groove 120 and the button 600 to become relatively large, which is very unsightly, and pollutants in the external environment can easily enter the first mounting groove 120, resulting in a poor user experience.

[0053] To solve this technical problem, reference Figures 5-9, in a specific embodiment, the mobile power supply 1000 further includes a stopper 800. The stopper 800 is fixedly provided at the notch of the first installation groove 120. In this way, the first installation groove 120 can be shielded, increasing the aesthetics of the mobile power supply 1000 while preventing pollutants in the external environment from entering the first installation groove 120. In order to expose the button 600, a profiling through hole 810 similar in shape to the button 600 is provided on the baffle for the button 600 to pass through.

[0054] Reference Figures 7-9 , in a specific embodiment, a mounting plate 1211 protrudes from the bottom 121 of the first installation groove 120. A slot 12111 is provided on the mounting plate 1211. An inverted hook 820 for cooperating with the slot 12111 is provided on one side of the stopper 800 facing the bottom 121 of the first installation groove 120. After the stopper 800 is inserted into the first installation groove 120, the inverted hook 820 will hook at the slot 12111, so that the stopper 800 is fixedly arranged at the notch of the first installation groove 120.

[0055] Optionally, the stopper 800 can also be fixedly arranged at the notch of the first installation groove 120 by means of adhesion.

[0056] Reference Figure 7 、 Figure 8 , in some embodiments, one of a limiting groove 610 and a limiting post 1212 is provided on the side of the button 600 facing the bottom 121, and the other of the limiting groove 610 and the limiting post 1212 is correspondingly provided on the bottom 121. The compression spring 700 is sleeved on the limiting post 1212, and the limiting groove 610 is used to accommodate the limiting post 1212 of the compression spring 700.

[0057] Specifically, the cooperation of the limiting groove 610 and the limiting post 1212 can restrict the position of the compression spring 700, avoiding the situation where the button 600 fails due to the displacement of the compression spring 700.

[0058] Reference Figure 7 、 Figure 8 , in some embodiments, one of a guiding groove 620 and a guiding post 1213 is provided on the side of the button 600 facing the bottom 121, and the other of the guiding groove 620 and the guiding post 1213 is correspondingly provided on the bottom 121. The cooperation of the guiding groove 620 and the guiding post 1213 can effectively restrict the moving path of the button 600, avoiding unnecessary shaking of the button 600 during movement.

[0059] Reference Figure 5, in some embodiments, the mobile power supply 1000 further includes a torsion spring 900 sleeved on the rotating shaft 500. Both ends of the torsion spring 900 are respectively abutted against the housing 100 and the hard cover plate 300 to store energy through deformation when the hard cover plate 300 is buckled at the first opening 111.

[0060] By implementing this embodiment, the hard cover plate 300 will pop open automatically after the button 600 is pressed. Specifically, in this embodiment, a torsion spring 900 is sleeved on the rotating shaft 500. Both ends of the torsion spring 900 are respectively abutted against the housing 100 and the hard cover plate 300. When the hard cover plate 300 is buckled at the first opening 111, the torsion spring 900 deforms and stores energy. At this time, the first buckle structure 400 and the second buckle structure 310 cooperate to restrict the energy release of the torsion spring 900. When the user presses the button 600, the first buckle structure 400 and the second buckle structure 310 are disengaged from the buckling relationship. At this time, the restriction of the torsion spring 900 is released, enabling the torsion spring 900 to release energy and drive the hard cover plate 300 to pop open. The user does not need to manually lift the hard cover plate 300, and the user experience is better.

[0061] Reference Figure 5 , in some embodiments, a pressing block 320 is provided on the side of the hard cover plate 300 facing the accommodating cavity 110. When the hard cover plate 300 is buckled at the first opening 111, the pressing block 320 abuts against the charging head group 210.

[0062] By implementing this embodiment, when the hard cover plate 300 is buckled at the first opening 111, the pressing block 320 on the hard cover plate 300 will abut against the charging head group 210, thereby applying a clamping force to the charging head group 210. In this way, the position of the charging head group 210 in the accommodating cavity 110 will be fixed and will not shake in the accommodating cavity 110. When the user uses it, the user will feel that the texture of the mobile power supply 1000 is better, improving the user experience.

[0063] It should be noted that the pressing block 320 can be made of flexible material or hard material, as long as it can provide a clamping force to the charging head group 210 when the hard cover plate 300 is buckled at the first opening 111 to prevent the charging head group 210 from shaking in the accommodating cavity 110. This embodiment does not make a limitation here.

[0064] Reference Figure 4 , in some embodiments, the first opening 111 communicates with the first surface 140 of the housing 100, the second opening 112 communicates with the second surface 150 of the housing 100, the first surface 140 is adjacent to the second surface 150, and the first opening 111 is directly communicated with the second opening 112.

[0065] Specifically, in the prior art, the first opening 111 and the second opening 112 are arranged at intervals. Therefore, it is necessary to align the wire body 220 of the charging cable 200 with the first opening 111 and the second opening 112. First, the wire body 220 is inserted into the accommodating cavity 110 from the first opening 111, and then the wire body 220 that enters the accommodating cavity 110 is passed out from the second opening 112. This is not only inconvenient, but also the wire body 220 is easily stuck in the accommodating cavity 110 and cannot come out when threading. Since the first opening 111 and the second opening 112 are directly connected in this embodiment, as long as the charging head group 210 of the charging cable 200 is placed into the accommodating cavity 110 by using the first opening 111, the wire body 220 of the charging cable 200 can naturally pass out from the second opening 112, so it is very convenient.

[0066] Reference Figure 5 , in a specific embodiment, a convex block 330 is provided on the side of the rigid cover plate 300 facing the second opening 112. When the rigid cover plate 300 is buckled at the first opening 111, the convex block 330 will enter the second opening 112, which can effectively reduce the exposure degree of the second opening 112 and increase the aesthetics of the mobile power supply 1000.

[0067] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Those skilled in the art can modify the technical solutions recorded in the above embodiments or equivalently replace some of the technical features; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
