[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 5 This utility model provides a portable charging device, including a housing 10, a power supply component, a data cable 20, and a limiting component 30. The power supply component is disposed within the inner cavity of the housing 10. A receiving groove 11 is provided on one side of the housing 10. The data cable 20 is disposed within the receiving groove 11, with one end of the data cable 20 fixed to the bottom wall of the receiving groove 11 and passing through the housing 10 to connect with the power supply component. The data cable 20 includes a plug 21 at the other end, which is used to insert into the data port of the device to be charged for charging. The limiting component 30 is disposed at one end within the receiving groove 11. Specifically, one end of the data cable 20 is fixed to one end of the bottom wall of the receiving groove 11, and the limiting component 30 is disposed at the other end of the bottom wall of the receiving groove 11. The limiting component 30 includes a limiting block 31, which is slidably connected to the housing 10. The sliding direction of the limiting block 31 is either away from or towards the data cable 20. The limiting block 31 has a limiting groove 32 corresponding to the plug 21 on the side near the data cable 20, and a spring piece (not shown) is provided in the limiting groove 32. In this embodiment of the utility model, there are two spring pieces, which are respectively provided on the upper and lower walls of the limiting groove 32. When the plug 21 is inserted into the limiting groove 32, the two spring pieces elastically clamp the plug 21, thereby fixing the movable end of the data cable 20.

[0032] When storing the data cable 20, the user slides the limiting block 31 away from the data cable 20 to lay the data cable 20 flat along the receiving groove 11. Then, the user slides the limiting block 31 closer to the data cable 20, causing the plug 21 to insert into the limiting groove 32. The spring clip holds the plug 21 inside the limiting groove 32, thereby fixing the movable end of the data cable 20. The portable charging device provided by this utility model can fix both ends of the data cable 20 after storing it, thus fixing the data cable 20 in the receiving groove 11, solving the technical problem that the data cable 20 is prone to loosening and thus causing the data cable 20 to detach from the receiving groove 11 on its own. It should be noted that since one end of the data cable 20 passes through the housing 10 and connects to the power supply component, a connection hole is provided on the bottom wall of the receiving groove 11 for the data cable 20 to pass through. Therefore, in order to make full use of the space of the receiving groove 11, the connection hole is located at one end of the receiving groove 11, that is, one end of the data cable 20 is fixedly connected to one end of the receiving groove 11. The data cable 20 is fixed at one end and fixedly connected to the receiving slot 11 at the other end.

[0033] Furthermore, the limiting block 31 is rotatably connected to a rotating shaft 33, the axis of which is collinear with the center line of the limiting block 31. The side of the limiting block 31 is positioned opposite to the side wall of the receiving groove 11, and the center line of the limiting block 31 is perpendicular to the side. Guide grooves 12 are provided on both side walls of the receiving groove 11, and both ends of the rotating shaft 33 are inserted into the guide grooves 12. The rotating shaft 33 can slide within the guide grooves 12, thereby allowing the limiting block 31 to slide on the guide grooves 12 via the rotating shaft 33. Optionally, the bottom surface of the limiting block 31 is in contact with the bottom wall of the receiving groove 11, and the side surface of the limiting block 31 is in contact with the side wall of the receiving groove 11, so that the limiting block 31 can move only in the direction away from or close to the data line 20; in addition, when the limiting block 31 is closest to the data line 20 (i.e., the side surface of the rotating shaft 33 is in contact with the side wall of the guide groove 12 near the end of the data line 20), the plug 21 is fully inserted into the limiting groove 32; when the limiting block 31 is furthest from the data line 20 (i.e., the side surface of the rotating shaft 33 is in contact with the side wall of the guide groove 12 away from the end of the data line 20), the plug 21 is completely disengaged from the limiting groove 32.

[0034] Furthermore, the bottom wall of the receiving groove 11 is provided with a mounting groove 13, and a spring 34 is installed in the mounting groove 13. One end of the spring 34 is fixedly connected to the bottom wall of the mounting groove 13, and the other end is slidably connected to the bottom wall of the limiting block 31. In the initial state, the spring 34 is in a compressed state. The mounting groove 13 is located on the center line of the bottom wall of the receiving groove 11 along the length direction, that is, the axis of the mounting groove 13 is perpendicular to the bottom wall of the receiving groove 11, and the axis of the mounting groove 13 intersects the center line of the bottom wall of the receiving groove 11 along the length direction, and the distance from the mounting groove 13 to both ends of the guide groove 12 is equal. When plug 21 is inserted into limiting slot 32 (at this time, limiting block 31 is close to data cable 20), spring 34 is located on the side of rotating shaft 33 away from data cable 20. Spring 34 exerts elastic force on limiting block 31, causing limiting block 31 to tend to rotate counterclockwise around rotating shaft 33. However, because the bottom surface of limiting block 31 is in contact with the bottom wall of receiving groove 11, limiting block 31 cannot rotate counterclockwise. When plug 21 is disengaged from limiting slot 32 (at this time, limiting block 31 is away from data cable 20, i.e., when the user removes data cable 20, the user slides limiting block 31 in the direction away from data cable 20), spring 34 is located on the side of rotating shaft 33 close to data cable 20. Spring 34 exerts elastic force on limiting block 31, causing limiting block 31 to tend to rotate clockwise around rotating shaft 33. A fan-shaped groove 14 is provided at the end of the bottom wall of receiving groove 11 near limiting component 30, allowing limiting block 31 to rotate clockwise. A lifting plate 35 is provided on the side of the limiting block 31 near the data cable 20, extending below the data cable 20. When the limiting block 31 rotates clockwise, the lifting plate 35 lifts the movable end of the data cable 20 out of the receiving groove 11. Because the data cable 20 is relatively small, the distance between the two side walls of the receiving groove 11 is correspondingly small. When the user needs to charge, it is not easy to remove the data cable 20 from the receiving groove 11. Through the above technical solution, the lifting plate 35 lifts the movable end of the data cable 20 and pries it out of the receiving groove 11, making it easier for the user to retrieve the data cable 20.

[0035] Furthermore, the sidewall of the receiving groove 11 is provided with an elastic element 40, which is a rubber sheet. When storing the data cable 20, during the process of laying the data cable 20 flat along the receiving groove 11, the middle section of the data cable 20 can be squeezed between the elastic elements 40. The elastic elements 40 fix the middle section of the data cable 20, further preventing the data cable 20 from easily becoming loose between itself and the receiving groove 11.

[0036] Furthermore, a data interface 15 and a power button 16 are provided at one end of the housing 10.

[0037] This utility model discloses a portable charging device. Specifically, when storing the data cable 20, the user slides the limiting block 31 away from the data cable 20, laying the data cable 20 flat along the receiving groove 11. Then, the user slides the limiting block 31 closer to the data cable 20, inserting the plug 21 into the limiting groove 32. The plug 21, entering the limiting groove 32, is held by a spring clip, thus fixing the movable end of the data cable 20. The portable charging device provided by this utility model, after storing the data cable 20, can fix both ends of the data cable 20, thereby securing the data cable 20 within the receiving groove 11. This solves the technical problem that the data cable 20 is prone to loosening between itself and the receiving groove 11, causing the data cable 20 to detach from the receiving groove 11 on its own.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
