[0020] The structure of this utility model will be further described below with reference to the accompanying drawings.

[0021] Reference Figures 1 to 4The portable retractable charging cable device of this utility model includes a housing 10 and a retractable data cable 20 disposed inside the housing. The charging plug 21 of the data cable is located outside the housing. The housing 10 includes an outer shell 11, an inner shell 12, and a locking member 13 for locking the outer shell and the inner shell. The outer shell 11 has an outer shell opening 111 on one side. The inner shell is slidably disposed inside the outer shell along the direction of the outer shell opening. The retractable data cable is disposed inside the inner shell. The opening of the outer shell 11 has an outer pressing edge 112, and the inner shell 12 has an inner pressing edge 121 corresponding to the outer pressing edge. In this embodiment, the inner shell 12 includes an inner shell body 123 and an inner shell back cover 124. A data cable receiving cavity 125 is formed between the inner shell body and the back cover. The retractable data cable is located inside the data cable receiving cavity, and the data cable charging plug is located outside the data cable receiving cavity. The inner shell body 123 has a data cable through hole 1231 for the data cable to extend and retract. In this embodiment, the telescopic structure of the telescopic data cable is similar to that of an existing tape measure. The telescopic data cable 20 includes a data cable mounting shell 201, an elastic support member, and a data cable body 202. The elastic support member is formed by the retraction of a spring sheet. The data cable body is wrapped around the elastic support member. When in use, the elastic support member retracts when the data cable is pulled, and when the data cable is released, the elastic support member rebounds and pulls the data cable to wrap around the elastic support member, thereby achieving automatic storage and convenient use.

[0022] In this embodiment, the data cable through-hole size 1231 is larger than the data cable wire size but smaller than the data cable charging plug size. The inner shell body also has a charging plug through-hole 1232 for the data cable charging plug to pass through. The charging plug through-hole and the data cable through-hole are connected by a connecting hole 1233, the size of which is only for the data cable wire to pass through. When installing the retractable data cable, after the data cable charging plug is passed through the charging plug through-hole, the data cable wire is pulled from the connecting hole into the data cable through-hole. At this time, the data cable charging plug is stuck above the data cable through-hole, so that when the data cable wire is retracted, the data cable charging plug will not retract into the data cable receiving cavity.

[0023] In this embodiment, the inner shell body 123 is provided with a data cable charging plug storage slot 1234, which is located outside the data cable through hole. A magnet 40 for attracting the data cable charging plug is provided at the bottom of the data cable charging plug storage slot. When not in use, the data cable charging plug is placed upside down in the data cable charging plug storage slot, and the magnet attracts and positions the data cable charging plug within the slot, preventing it from swinging or colliding and thus reducing the risk of damage.

[0024] In this embodiment, the bottom of the data cable charging plug storage slot 1234 is provided with a recessed magnet mounting slot 1235, and the bottom of the data cable charging plug storage slot is provided with a pressure plate 125 for pressing and fixing the magnet. During installation, the magnet is placed in the magnet mounting slot, and then the pressure plate is pressed on the magnet. In this embodiment, the pressure plate is fixed to the bottom of the data cable charging plug storage slot by adhesive; in specific implementations, it can also be fixed by screws. The pressure plate 125 is provided with a pressure plate through hole 1251 for the data cable charging plug to pass through. The data cable charging plug extends out from the pressure plate through hole and is placed in the data cable charging plug storage slot.

[0025] In this embodiment, the inner shell body 123 and the inner shell rear cover 123 are detachably connected by fixing screws 122. The inner shell body 123 has a threaded hole, and the inner shell rear cover has an inner shell screw through hole that mates with the threaded hole. The locking member 13 is the fixing screw 122, and the outer shell has an outer shell screw through hole that mates with the fixing screw. The fixing screw passes through the outer shell screw through hole and the inner shell screw through hole respectively and is locked with the threaded hole. The locking member locks the inner shell body, the inner shell rear cover, and the outer shell together.

[0026] In this embodiment, the outer shell and inner shell are provided with corresponding wiring holes 30. When the charging cable device of this utility model does not have an internal power supply, the wiring holes are used for connecting the data cable to the outside.

[0027] When this portable retractable charging cable device is installed in a bag or backpack, the inner and outer pressure edges press down on the flexible mounting strap on the bag or backpack. Then, the locking mechanism locks the outer shell and inner shell together, thus securing the retractable charging cable device to the bag or backpack for easy carrying and use.

[0028] Although specific embodiments of the present invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of the present invention.
