[0037] Please refer to Figures 1 to 6 The utility model embodiment provides a kind of mobile power supply 100, comprising: power supply body 1, charging wire 2, storage groove 3 and fixed structure.

[0038] Optionally, power supply body 1 includes shell 11, and battery unit (not shown in drawing) in shell 11, circuit board (not shown in drawing). Charging wire 2 one end is electrically connected with battery unit in power supply body 1, the other end from power supply body 1. It can be understood that the one end of charging wire 2 is electrically connected with battery unit by circuit board. Charging wire 2 includes wire body 21 and the charging connector 22 for electronic equipment (not shown in drawing) charging at the end of wire body 21.

[0039] Storage groove 3 is arranged on the side of power supply body 1, and the shape is matched with the shape of charging wire 2, for charging wire 2 winding storage.In the embodiment, power supply body 1 is substantially cuboid shape, therefore, storage groove 3 is arranged around two connected sides. Of course in other embodiments, storage groove 3 can also surround one side, three sides or four sides. Or, when power supply body 1 is cylindrical, storage groove 3 is at least partially arranged around the side of power supply body 1. As long as it is arranged on the side of power supply body 1, it can be used for charging wire 2 to be attached and wound for storage. The fixed structure is arranged on the side of power supply body 1, for keeping charging wire 2 in storage groove 3.

[0040] Since the side of the power supply body 1 of the mobile power supply 100 is provided with the storage groove 3 matched with the shape of the charging wire 2 for winding and storing the charging wire 2, and the fixed structure is arranged on the side of the power supply body 1 for keeping the charging wire 2 in the storage groove 3. In this way, when not in use, the charging wire 2 can be wound and stored in the storage groove 3 on the side of the power supply body 1, and fixed by the fixed structure. In this way, it has the advantages of convenient and neat charging wire 2 storage.

[0041] Optionally, please refer to Figure 2 And Figure 4In the embodiment, the receiving groove 3 includes a wire groove 31 shaped to match the shape of the wire body 21 of the charging cord 2, and a connector groove 33 communicating with the wire groove 31 and shaped to match the shape of the charging connector 22 of the charging cord 2. The fixing structure includes a clamping member 41 and a plug hole o. The clamping member 41 is arranged on the side wall of the wire groove 31 for fixing the wire body 21 of the charging cord 2 in the wire groove 31. Specifically, the clamping member 41 is a clamping protrusion arranged on the inner walls on both sides of the wire groove 31 for clamping the wire body 21 of the charging cord 2. It can be understood that the wire body 21 of the charging cord 2 is mostly provided with an elastic insulating sheath, so as long as the distance between the two clamping protrusions is less than the width of the wire body 21, the wire body 21 of the charging cord 2 can be clamped in the wire groove 31 by the clamping protrusions. Of course, in other embodiments, the clamping member 41 is a clamping protrusion arranged on the inner wall of one side of the wire groove 31 for clamping the wire body 21 of the charging cord 2 by cooperating with the inner wall of the other side of the wire groove 31. In addition, the clamping member 41 can also be arranged in multiple in the extension direction of the wire groove 31, which is not specifically limited here. The plug hole o is arranged on the side wall of the connector groove 33 away from the wire groove 31 for inserting and fixing the charging connector 221 of the charging connector 22. Specifically, the shape of the plug hole o matches the shape of the charging connector 221 of the charging connector 22. In this way, when the charging cord 2 is wound and received, the wire body 21 and the charging connector 22 can be fixed at the same time by the fixing structure, and the fixing effect is more stable.

[0042] Since the thicknesses of the wire body 21 and the charging connector 22 of the charging cord 2 are different, and the charging connector 221 of the charging connector 22 is inserted in the plug hole o, in order to make the charging connector 22 of the charging cord 2 more smoothly inserted or withdrawn when the charging cord 2 is wound and received in the receiving groove 3 or taken out from the receiving groove 3, and not blocked. Alternatively, please refer to Figure 3 、 Figure 4 and Figure 6 In the embodiment, the wire groove 31 and the connector groove 33 have a transition plane 32 arranged obliquely downward from the wire groove 31 to the connector groove 33.

[0043] In order to facilitate the user to take out the charging cord 2 from the receiving groove 3 when charging is needed, alternatively, please refer to Figure 2 、 Figure 4 and Figure 5In the embodiment, the side surface is provided with an inclined gap 111 which is inclined downward from the end far away from the charging connector 22 to the end close to the charging connector 22, for pushing the charging interface 221 of the charging connector 22 out of the insertion hole o by the user. The side surface corresponding to the position of the receiving groove 3 is provided with a wire pulling gap 112 for pulling the charging wire 2. Specifically, the wire pulling gap 112 can be one or multiple, which is not specifically limited here. Thus, when the charging wire 2 needs to be taken out, the charging connector 22 can be pushed out of the connector groove 33 at the position of the inclined gap 111, at which time the charging connector 22 can be smoothly pushed out along the inclined gap 111 without being blocked. Then the charging wire 2 can be pulled out in the wire pulling gap 112.

[0044] In order to make the appearance of the mobile power supply 100 consistent, optionally, please refer to Figure 2 and Figure 4 In the embodiment, the depth of the wire groove 31 is equal to the thickness of the wire body 21 of the charging wire 2, and the depth of the connector groove 33 is equal to the thickness of the charging connector 22. Thus, when the charging wire 2 is wound and received in the receiving groove 3, the outer surface of the charging wire 2 is in the same plane as the side surface of the power supply body 1.

[0045] Optionally, please refer to Figure 1 In the embodiment, the side surface of the power supply body 1 is provided with a plurality of anti-skid lines 12 which are spaced apart and extend along the circumference of the side surface. Thus, when the mobile power supply 100 is held by hand, the friction between the hand and the side surface of the power supply body 1 is greater.

[0046] In order to facilitate the charging wire 2 to meet the needs of different lengths, optionally, in the embodiment, the power supply body 1 further includes a wire winding mechanism (not shown in the figure) located in the shell 11. Part of the charging wire 2 can be received in the shell 11 by the wire winding mechanism. Specifically, the wire winding mechanism is an internal wire winding disc, which is a prior art and will not be described in detail here.

[0047] Optionally, please refer to Figure 1 In the embodiment, in order to be reusable, the battery unit is a rechargeable battery. In addition, one side surface of the power supply body 1 is provided with an input interface 5, an output interface 6 and a button switch 7 which are electrically connected with the circuit board. It can be understood that the input interface 5, the output interface 6 and the button switch 7 are arranged in the side surface which does not have the receiving groove 3.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not cause the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
