One end of the data cable 40 is provided with a plug end 41, the other end of the data cable is provided with a movable end 45, the plug end 41 is detachably connected in the accommodating groove 30 in a plug manner, and the data cable 40 and the functional component 50 are electrically connected through the plug end 41; the movable end 45 is detachably connected in the receiving recess 30.

Specifically, for the convenience of use, the docking station needs to have a data cable 40, where the data cable 40 is generally used to connect to an external device to be expanded, such as an electronic device such as a mobile phone, a tablet computer or a notebook computer, so that a screen of the external device to be expanded can be expanded to other external large-screen display devices through the data cable 40, and other interfaces on the docking station can be accessed through a data line, such as accessing data of a corresponding memory card inserted into the SD card or TF card socket 57; the external inserted wired network can be accessed through the RJ45 female socket 59, so that the mobile device is accessed into a stable wired network, and stable network data information can be transmitted. Similarly, the external mobile device may be correspondingly charged through the data cable 40.

However, the data cable 40 of the conventional docking station protrudes outside the docking station body 10, which results in inconvenient storage and carrying, and frequent folding storage also easily damages the data cable 40. Because the data cable 40 of the conventional docking station is fixedly connected to the docking station, the entire docking station can be replaced only after the cable is disconnected or damaged, which affects the overall service life of the docking station. Accordingly, the present patent contemplates the data cable 40 being receivable within the docking body 10, thereby facilitating the reception of the data cable 40 within the docking body 10 when not in use.

Specifically, in order to further improve the convenience of carrying and the use experience of the user, the housing 12 of the docking station may be further configured in a flat cylindrical shape, that is, a flat cylindrical structure, and due to its flat configuration, the space inside the bag is relatively not easy to occupy when the docking station is placed inside the bag. In addition, the distance between the two plate-like structures 14 is preferably the distance between two parallel lines at the upper and lower ends thereof in the cross section as shown in fig. 9; the distance between the two arc structures 13 is preferably the distance between the circular dots of the circular arcs at the left and right ends in the cross section as shown in fig. 9.

As shown in fig. 1, 3, 6, 8 and 9, preferably, a bracket 20 is disposed on one of the plate-like structures 14 of the housing 12, and the bracket 20 is rotatably connected to the plate-like structure 14 and can be accommodated in the plate-like structure 14; the plate-shaped structure 14 is provided with a rotating hole 16, a containing groove 17 and a limiting block 18, the bracket 20 is provided with a rotating shaft 21 and a torsion spring (not shown in the figure), the rotating shaft 21 and the rotating hole 16 are matched with each other to form a rotating connection, the bracket 20 can be contained in the containing groove 17 to form a containing mode, and the bracket 20 can rotate a certain angle and is abutted against the limiting block 18 to form a supporting mode; one end of the torsion spring abuts against the plate-like structure 14 and the other end abuts against the bracket 20, the torsion spring being used to switch the bracket 20 between a storage mode and a support mode.

Specifically, in order to improve the heat dissipation effect of the docking station during long-time high-power use, a bracket 20 may be further disposed on one plate structure 14, and the docking station is lifted away from the placement plane by using the bracket 20, so as to form a certain heat dissipation space, so that air around the docking station can circulate relatively, and further the heat dissipation effect is enhanced.

After the use, the cables on the corresponding female seats are pulled out, and then the data cable 40 is placed in the receiving groove 30 of the body 10, and the whole data cable 40 is received in the receiving groove 30, so that the whole docking station is convenient to carry.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
