[0028] In the initial state, the wire body of the data line 300 can be wound in the storage module 400, when the wire body of the data line 300 is wound in the storage module 400, the second limiting piece 320 will abut against the first limiting piece 123, so that the interface 310 is exposed outside the cover plate 120 and the interface 310 cannot be retracted into the containing cavity through the wire passing port 122, and the interface 310 exposed outside the cover plate 120 can be stored in the containing groove 121; when it is needed to use, the interface 310 can be taken out from the containing groove 121 and pulled outwards to pull the wire body of the data line 300 at the same time, and the wire body of the data line 300 can drive the storage module 400 to rotate under the external force, so that the wire body wound on the storage module 400 is released to the outside of the shell 100.
[0029] The existing mobile power supply on the market needs to be connected with a data line when in use, so that the use of the mobile power supply is very inconvenient; in order to solve the above problem, some mobile power supplies with data lines appear on the market, at present, generally, the shell of the mobile power supply is designed in the form of splicing of an upper shell and a lower shell, and two wire passing grooves are arranged on the upper shell and the lower shell respectively, when the retractable data line is placed in the lower shell, one end of the data line with the interface 310 is pulled out of the lower shell, and finally the upper shell is covered on the lower shell, so that the two wire passing grooves are combined into the wire passing port 122; the design is not only complex in assembly, but also the wire passing port 122 is spliced by the wire passing grooves of the upper and lower shells, and the structural strength is low, and the wire passing port 122 is easy to crack or damage under long-term repeated pulling of the data line.
[0030] In the embodiment, a mobile power supply is designed, which comprises a shell 100, a battery module 200, a data line 300 and a storage module 400. The shell 100 comprises a shell body 110 and a cover plate 120. The cover plate 120 is connected with the shell body 110 to form a containing cavity. The battery module 200 and the storage module 400 are arranged in the containing cavity. The cover plate 120 is provided with a containing groove 121 on the outside. A wire passing opening 122 is arranged in the containing groove 121. One end of the data line 300 is electrically connected with the battery module 200. The other end of the data line 300 is provided with an interface 310. The interface 310 is exposed outside the cover plate 120 through the wire passing opening 122. A first limiting piece 123 is arranged on the inside of the cover plate 120 corresponding to the wire passing opening 122. A second limiting piece 320 is arranged on the wire body of the data line 300 close to the interface 310. In the initial state, the wire body of the data line 300 is wound in the storage module 400. The second limiting piece 320 abuts against the first limiting piece 123, so that the interface 310 is limited in the containing groove 121. According to the scheme, the wire passing opening 122 is directly arranged on the cover plate 120, and the first limiting piece 123 is arranged at the wire passing opening 122. When installed, only the interface 310 of the data line 300 needs to be exposed outside the cover plate 120 through the first limiting piece 123 and the wire passing opening 122, and the second limiting piece 320 is assembled to limit. The installation is simpler, and the structure strength of the wire passing opening 122 is higher.
[0031] In one embodiment, referring to Figures 1 to 3 The first limiting piece 123 is an elastic piece 123 with an annular groove.

In the initial state, the second limiting piece 320 can be accommodated in the wire passing opening 122 and abut against the first limiting piece 123. When the interface 310 is exposed outside the cover plate 120 through the first limiting piece 123 and the wire passing opening 122 in sequence, the second limiting piece 320 can be assembled to the wire body of the data line 300 exposed on one side of the cover plate 120. When the wire body of the data line 300 is wound and stored in the storage module 400 inside the containing cavity, the second limiting piece 320 can be driven to move towards the first limiting piece 123 until the second limiting piece 320 abuts against the first limiting piece 123, so as to limit the interface 310, to prevent the interface 310 from retracting into the containing cavity.
[0032] Wherein, the second limiting member 320 can be assembled to the data line 300 first, and when the first limiting member 123 is assembled to the inner side of the cover plate 120, the first limiting member 123 can be pried open by the elasticity of the first limiting member 123 when the second limiting member 320 and the interface 310 pass through the annular groove of the first limiting member 123, and the first limiting member 123 can be reset after the interface 310 and the second limiting member 320 pass through the first limiting member 123 in sequence, so as to limit the interface 310 in the accommodating groove 121 outside the cover plate 120 and limit the second limiting member 320 at the wire passing hole 122.
[0033] In one of the embodiments, referring to Figures 1 to 3 , the inner side of the cover plate 120 is provided with a first positioning member 124 and a second positioning member 125, and the elastic member 123 is provided with a first positioning groove 1231 and a second positioning groove 1232, and the first positioning member 124 and the second positioning member 125 are inserted into the first positioning groove 1231 and the second positioning groove 1232, respectively.

[0035] In one of the embodiments, referring to Figures 1 to 3 , in order to prevent the data line 300 from pulling the elastic member 123 during stretching and contraction, the first positioning member 124 is further provided with a buckle 1241, and the first positioning groove 1231 is further provided with a notch 1233, and when the first positioning member 124 is clamped into the first positioning groove 1231 and the second positioning member 125 is clamped into the second positioning groove 1232 to fix the elastic member 123 to the inner side of the cover plate 120, the buckle 1241 on the first positioning member 124 can be tightly buckled in the notch 1233 in the first positioning groove 1231, so as to prevent the data line 300 from moving the elastic member 123 into the accommodating cavity when it is retracted, thereby improving the structural stability.
[0036] In one of the embodiments, referring to Figures 1 to 3The fixing structure can be a clamping hook structure or a magnetic attraction structure. Preferably, the fixing structure is a magnet, and the inner side of the cover plate 120 is provided with a mounting cavity 126 corresponding to the position of the accommodating groove 121, and the magnet is mounted in the mounting cavity 126.
[0037] In one embodiment, referring to Figures 2 to 4 The accommodation module 400 includes a base 410 and a rotating table 420. The rotating table 420 is arranged on the base 410, and the side of the rotating table 420 facing the base 410 is provided with a winding drum 421 for winding the data line 300. The rotating table 420 can rotate relative to the base 410 to realize unwinding and winding of the data line 300.
[0038] Specifically, referring to Figures 2 to 4 The accommodation module 400 is used to wind the data line 300 in a state that the data line 300 is not used, so as to improve the carrying convenience of the power bank. The accommodation module 400 includes a support 500 and a rotating table 420. The rotating table 420 is arranged on the base 410.

The center of the inner side wall of the base 410 is provided with a column 411, and the center of the rotating table 420 is provided with a clamping groove 422. When the rotating table 420 is mounted on the base 410, one end of the column 411 will pass through the through hole and be clamped into the clamping groove 422 in the center of the rotating table 420, so as to movably limit the rotating table 420 on the base 410. When the part of the data line 300 exposed outside the cover plate 120 is pulled by an external force, the wound data line 300 moves under the action of the pulling force and drives the rotating table 420 to rotate relative to the base 410, so as to release the wound line part to the outside of the shell 100.
[0039] In one embodiment, referring to Figures 2 to 4 The accommodation module 400 further includes a reset structure 430 arranged on the rotating table 420, so as to drive the rotating table 420 to reversely rotate and reset.
