Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a mechanism for preventing the charging cable from detaching from a portable power bank, as shown in the following figure. Figures 1-2 as well as Figures 6-7 The system includes a charging cable 200 and a storage cable 400. The charging cable 200 has a charging connector 100 at one end, and the storage cable 400 has a storage head 300 at one end. A storage groove 310 is provided on one side of the storage head 300 for inserting one end of the charging connector 100. An anti-detachment device is provided between the inner wall of the storage groove 310 and the outer peripheral wall of the end of the charging connector 100 inserted into the storage groove 310. This anti-detachment device prevents the charging connector 100 from accidentally detaching from the storage groove 310 after resetting. Specifically, after using the charging connector 100, the user resets the charging connector 100 by inserting one end of the charging connector 100 into the storage groove 310 of the storage head 300 and rotating the charging connector 100. This allows the anti-detachment device to securely lock one end of the charging connector 100 within the storage groove 310, preventing the charging connector 100 from easily detaching after resetting and thus avoiding accidental detachment from the storage groove 310. After the charging connector 100 is reset, one end of the charging cable 200 connects to one end of the storage cable 400, allowing the charging cable 200 to act as a lanyard for the power bank so that the user can hang the power bank on their hand. The anti-detachment device ensures that one end of the charging connector 100 is stably engaged with the storage head 300, preventing the charging connector 100 from accidentally detaching from the storage slot 310. Furthermore, when the user uses the charging cable 200 as a lanyard to hang the power bank on their hand, it prevents the power bank from accidentally falling. This power bank has a simple overall structure with its built-in anti-detachment charging cable mechanism.

[0021] Furthermore, referring to Figures 2-7The anti-detachment device includes an anti-detachment protrusion 510 and an anti-detachment groove 520 that mates with the anti-detachment protrusion 510. The anti-detachment protrusion 510 and the anti-detachment groove 520 are respectively disposed on the inner wall of the storage groove 310 and on the outer peripheral wall of the end where the charging connector 100 is inserted into the storage groove 310. Specifically, in this embodiment, the inner wall of the storage groove 310 is provided with the anti-detachment protrusion 510, and the outer peripheral wall of the end where the charging connector 100 is inserted into the storage groove 310 is provided with the anti-detachment groove 520 that mates with the anti-detachment protrusion 510. After the charging connector 100 is reset, one end of the charging connector 100 is inserted into the storage groove 310 of the storage head 300. The charging connector 100 is then rotated so that the anti-detachment protrusion 510 is placed into the anti-detachment groove 520. The anti-detachment protrusion 510 and the anti-detachment groove 520 engage, ensuring that the end of the charging connector 100 inserted into the storage groove 310 is securely assembled with the storage head 300, preventing the charging connector 100 from accidentally detaching from the storage groove 310. In some embodiments, an anti-detachment protrusion 510 is provided on the outer peripheral wall of the end of the charging connector 100 inserted into the storage groove 310, and an anti-detachment groove 520 that mates with the anti-detachment protrusion 510 is provided on the inner wall of the storage groove 310.

[0022] In this embodiment, the side of the anti-detachment protrusion 510 that mates with the anti-detachment groove 520, and the side of the anti-detachment groove 520 that mates with the anti-detachment protrusion 510, are both designed as arc-shaped surfaces. The arc-shaped surface design ensures the smoothness of rotation of the charging connector 100 after it is placed into the storage slot 310, and also reduces the frictional resistance and jamming sensation when rotating the charging connector 100 in the opposite direction, making the operation of unlocking the charging connector 100 easier and smoother.

[0023] Furthermore, referring to Figures 6-7 The charging connector 100 includes a connector body 110, an output connector 120, and a first protective sleeve 130. One side of the connector body 110 is connected to the charging cable 200; one end of the output connector 120 is connected to the other side of the connector body 110, and its output end is used to connect to a mobile electronic device to transmit power to the device; the first protective sleeve 130 is disposed on the outer periphery of the output connector 120, located between the output end and the side of the connector body 110 away from the charging cable 200. An anti-detachment groove 520 is provided on the outer peripheral wall of the first protective sleeve 130. The connector body 110, the output connector 120, and the first protective sleeve 130 cooperate to connect to and transmit power to the mobile electronic device while ensuring that the charging connector 100 can be securely locked into the storage slot 310 after use. After the charging connector 100 is reset, the output end of the output connector 120 is placed into the storage slot 310, and the storage head 300 can protect the output connector 120 of the charging connector 100 to prevent it from being exposed to the external environment for a long time. In this embodiment, the first protective sleeve 130 can also protect the other end of the output connector 120.

[0024] Furthermore, referring to Figures 6-7 The inner wall of the storage groove 310 is provided with a protrusion 600; an anti-detachment protrusion 510 is provided in the middle of the protrusion 600; a limiting groove 710 is provided on both sides of the anti-detachment protrusion 510 on the protrusion 600; a limiting protrusion 720 that cooperates with the limiting groove 710 is provided on the outer peripheral wall of the first protective sleeve 130 on both sides of the anti-detachment groove 520. In this embodiment, when the user wants to reset the charging connector 100, the charging connector 100 of the charging cable 200 needs to be inserted into the storage head 300 of the storage cable 400, and then the charging connector 100 is rotated clockwise. During the clockwise rotation of the charging connector 100, refer to Figure 4 When the charging connector 100 is rotated clockwise to 65°, the limiting protrusions 720 on both sides of the anti-detachment groove 520 on the outer peripheral wall of the first protective sleeve 130 begin to rub against the limiting grooves 710 on both sides of the anti-detachment protrusion 510 on the protrusion 600. Simultaneously, the anti-detachment protrusion 510 also rubs against the outer peripheral wall of the first protective sleeve 130. (Refer to...) Figure 5 When the charging connector 100 is rotated clockwise to 78°, the limiting protrusion 720 on one side of the anti-detachment groove 520 rubs against the limiting groove 710, and the limiting protrusion 720 on the other side of the anti-detachment groove 520 interferes with the anti-detachment protrusion 510. At this time, the user can clearly feel the resistance when rotating. (Refer to...) Figure 2 When the charging connector 100 is rotated clockwise to 90°, a "click" sound will be heard, indicating that the anti-detachment protrusion 510 is inserted into the anti-detachment groove 520, and the limiting protrusions 720 on both sides are inserted into the limiting grooves 710 on both sides, indicating that the charging connector 100 has been rotated into place, and at this time the charging connector 100 is locked with the storage head 300. When the user unlocks the charging connector 100, they only need to rotate the charging connector 100 counterclockwise. In some embodiments, counterclockwise rotation can also reset the charging connector 100, and clockwise rotation can lock the charging connector 100. In this embodiment, two protrusions 600 are symmetrically arranged.

[0025] Furthermore, the side of the limiting protrusion 720 that mates with the limiting groove 710, and the side of the limiting groove 710 that mates with the limiting protrusion 720, are both designed as curved surfaces. The curved surface design reduces frictional resistance and jamming when rotating the charging connector 100 in the reverse direction, making the operation of unlocking the charging connector 100 easier and smoother.

[0026] In this embodiment, refer to Figure 3 as well as Figures 6-7The power bank's built-in charging cable anti-detachment mechanism also includes a limiting block 800. The limiting block 800 is disposed on the inner wall of the storage groove 310 and located on the side of the protrusion 600 near the bottom wall of the storage groove 310. The charging connector 100 also includes a second protective sleeve 140. The second protective sleeve 140 is disposed on the outer periphery of the output connector 120 and located between the output end and the first protective sleeve 130. The second protective sleeve 140 is used to cooperate with the limiting block 800. The cross-sectional area of ​​the second protective sleeve 140 is larger than the cross-sectional area of ​​the first protective sleeve 130. The side of the limiting block 800 that cooperates with the second protective sleeve 140 is set as a slope 810. The high end of the slope 810 is located on the side of the limiting block 800 away from the anti-detachment protrusion 510, and the low end is located on the side of the limiting block 800 near the anti-detachment protrusion 510. The limiting block 800 restricts the rotation range of the charging connector 100, preventing excessive rotation by the user that could cause it to disengage and damage the built-in anti-disengagement mechanism of the power bank. The high end of the inclined surface 810 is located on the side of the limiting block 800 away from the anti-disengagement protrusion 510, and the low end is located on the side of the limiting block 800 closer to the anti-disengagement protrusion 510. This prevents interference with the normal rotation and reset of the charging connector 100, while also preventing excessive rotation. Furthermore, two limiting blocks 800 are symmetrically arranged.

[0027] This embodiment also relates to a portable power supply, as shown in the reference. Figure 8 The power bank includes: a built-in anti-detachment mechanism for the charging cable as described above, and a power bank body 900; the other end of the charging cable 200 and the other end of the storage cable 400 are both fixedly mounted on the power bank body 900. This power bank has the advantage of being easy to carry. The power bank body 900 contains a control circuit board (not shown in the attached drawing), battery cells (not shown in the attached drawing), etc., wherein the charging cable 200 is electrically connected to the control circuit board and the battery cells.

[0028] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
