[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Existing power bank lanyard and output cable integrated connection structure, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the connection structure between the protective cover and the handle in the prior art; one end of the output cable is a charging port, and the handle 3' is provided on the output cable. The handle 3' serves as a force-bearing point for easy gripping by the user. The connecting cable is fixed to the shell, and a protective cover is provided on the connecting cable. A straight-insertion buckle is designed on the handle and the protective cover 2' to achieve the connection. Figure 1 As shown, the protective case 2' has a slot 7, and the handle 3' has a hook 8, which are locked together. When charging is needed, simply hold the handle and pull the charging port 4 out of the protective case.

[0035] The applicant has discovered that the prior art has at least the following technical problems: In order to ensure the reliability of the connection between the handle and the protective cover, when the interference fit between the hook 8 and the slot 7 is large, a large insertion and removal force is required, making it difficult to pull out the charging port and resulting in a poor user experience. If the interference fit of the hook design is small, the handle and the protective cover are easy to detach. When used as a hanging rope, it is easy to fall off and drop the power supply. The straight-insertion hook has no elasticity and the back-and-forth interference friction causes greater wear with increased use, leading to the hook loosening.

[0036] To address the aforementioned issues, this utility model provides a lanyard-integrated output cable connection structure and a power bank. The structure uses a two-slot design to achieve a sliding snap-fit ​​fixation of the protrusion, preventing the handle from detaching from the protective cover. Furthermore, the method of rotating to separate the handle and the protective cover facilitates the application of force.

[0037] The following is combined Figures 2-7 The technical solution provided by this utility model will be described in more detail.

[0038] Example 1:

[0039] The present invention provides a lanyard output integrated cable connection structure, including a connecting cable 1, a protective sleeve 2, and a charging cable 5 having a handle portion 3 and a charging port 4. The protective sleeve 2 is located at the end of the connecting cable 1 and is rotatably configured. A protrusion 30 is provided on the handle portion 3. A guide groove 21 and a fixing groove 22 are provided on the inner wall of the protective sleeve 2. The guide groove 21 passes through the open end of the protective sleeve 2, and the end of the fixing groove 22 opposite to the guide groove 21 is a closed end. When the charging port 4 is inserted into the protective sleeve 2, the protrusion 30 can extend into the guide groove 21. When the protective sleeve 2 is rotated, the protrusion 30 can slide along the fixing groove 22 and be locked and fixed at the closed end of the fixing groove 22.

[0040] One end of the connecting wire 1 is fixedly connected to the housing 6, while the other end is rotatably connected to the protective sleeve 2. The two can rotate relative to each other along the radial plane of the protective sleeve 2. One end of the charging wire 5 is fixed to the housing 6 of the power bank and electrically connected to the charging circuit inside the housing 6. As a mature technology in the power bank field, it will not be described in detail here.

[0041] In this embodiment, the integrated lanyard output cable connection structure aligns the protrusion 30 on the handle 3 with the guide groove 21. The charging port 4 is inserted into the protective sleeve 2. Rotating the protective sleeve 2 causes relative rotation between the protective sleeve 2 and the handle 3, allowing the protrusion 30 to slide into the fixing groove 22 and move to the closed end of the fixing groove 22 for locking and fixing, preventing the handle 3 from detaching from the protective sleeve 2. Conversely, rotating the handle 3 removes the charging port 4, enabling it to function as a charging cable 5. This integrated lanyard output cable connection structure uses a two-slot structure to achieve a sliding locking and fixing of the protrusion 30, preventing the handle 3 from detaching from the protective sleeve 2. Furthermore, the method of rotating to separate the handle 3 and the protective sleeve 2 facilitates the application of force.

[0042] As an optional implementation, see Figure 7 As shown, the guide groove 21 extends along the axial direction of the protective sleeve 2.

[0043] When the protrusion 30 on the handle 3 is aligned with the guide groove 21, the charging port 4 can be inserted into the protective sleeve 2. When the charging port 4 is inserted into the protective sleeve 2, the protrusion 30 reaches the connection between the fixing groove 22 and the guide groove 21. By rotating the protective sleeve 2, the protrusion 30 can move relative to the closed end of the fixing groove 22, thereby achieving the snap-fit ​​fixation between the protrusion 30 and the fixing groove 22.

[0044] As an optional implementation, see Figure 7 As shown, the fixing groove 22 is an arc-shaped groove and is set around the central axis of the protective sleeve 2.

[0045] The above structure enables the protrusion 30 to slide into the fixing groove 22 and be locked in place with the closed end of the fixing groove 22 when the protective sleeve 2 is rotated.

[0046] As an optional implementation, see Figure 6 and Figure 7 As shown, the inner wall of the fixing groove 22 in this embodiment is provided with groove protrusions 23. The groove protrusions 23 are located at the closed end of the fixing groove 22, and the protrusions 30 can be engaged and fixed with the groove protrusions 23.

[0047] Specifically, the protrusion 30 is engaged and fixed with the protrusion 23 inside the groove of the fixing groove 22. The interference fit between them does not affect the insertion and extraction force. In this embodiment, the protrusion 30 is separated from the fixing groove 22 by rotational torsion. When the protrusion 30 enters the connection between the fixing groove 22 and the guide groove 21, the charging port 4 can be directly pulled out. Rotational torsion is more convenient to apply force than insertion and extraction force.

[0048] See Figure 2 As shown, when the handle part 3 is fixed to the protective cover 2 and the charging cable 5 and the connecting cable 1 form a hanging rope structure, the weight of the power bank will not cause the handle part 3 to detach from the protective cover 2 when the power bank is suspended or held by hand, resulting in good structural stability.

[0049] As an optional implementation, see Figure 5 As shown, the handle part 3 includes a handle body 31 and a boss 32 that are fixedly connected. The outer diameter of the boss 32 is smaller than the outer diameter of the handle body 31. The handle body 31 and the boss 32 have a stepped structure. The charging port 4 is fixed on the boss 32. The outer diameter of the boss 32 is smaller than the outer diameter of the handle body 31. The protrusion 30 is fixed on the side wall of the boss 32.

[0050] The protrusion 32 extends into the protective sleeve 2, and the handle body 31 is located outside the protective sleeve 2. The above-mentioned structure of the handle part 3 facilitates the setting of the protrusion 30, making it convenient to connect and disassemble the handle part 3 and the protective sleeve 2.

[0051] As an optional implementation, see Figures 2-6 As shown, in this embodiment, there are at least two protrusions 30, which are arranged at intervals around the central axis of the handle portion 3. The positions and numbers of the fixing grooves 22 and guide grooves 21 correspond one-to-one with the protrusions 30.

[0052] The above structure allows for multi-point connection between the handle part 3 and the protective cover 2, thereby improving the stability of the connection structure.

[0053] As an optional implementation, see Figures 4-6 As shown, the protrusion 30 is arranged radially along the handle portion 3 and has a cylindrical structure.

[0054] The above structure facilitates the sliding connection between the protrusion 30 and the guide groove 21, and also facilitates the sliding of the protrusion 30 to the closed end of the fixing groove 22, thereby realizing the snap-fit ​​fixation between the protrusion 30 and the protrusion 23 in the groove.

[0055] To facilitate the rotatable connection of connecting wire 1 and protective sleeve 2, see [link / reference]. Figure 5 As shown, the connecting wire 1 includes a wire body 11 and an end cap 12. One end of the wire body 11 is fixed to the housing 6, and the other end is fixed to the end cap 12. The end cap 12 is located inside the protective sleeve 2, and the protective sleeve 2 can rotate relative to the end cap 12 under external force. Specifically, one of the end cap 12 and the inner wall of the protective sleeve 2 is provided with a protruding ring 121, and the other is provided with an annular groove 24. The protruding ring 121 is located inside the annular groove 24 and can rotate relative to the central axis of the protective sleeve 2. See also... Figure 5 In this embodiment, the protruding ring 121 is disposed on the outer wall of the end head 12, and the annular groove 24 is disposed on the inner wall of the protective sleeve 2. Both are disposed around the axis of the protective sleeve 2.

[0056] The mating structure of the protruding ring 121 and the annular groove 24 ensures that the protective sleeve 2 can only rotate relative to the end head 12 along the radial plane of the protective sleeve 2, thereby ensuring that the protruding part 30 can slide into and be fixed in the fixing groove 22.

[0057] Example 2:

[0058] See Figure 2 and Figure 3 As shown, this embodiment provides a power bank, including a housing 6 and the above-mentioned lanyard output integrated cable connection structure. One end of the connecting cable 1 is fixed to the housing 6, and the end of the charging cable 5 away from the charging port 4 is fixed to the housing 6.

[0059] The power bank in this embodiment is easy to carry, and the connection structure between the handle 3 and the protective cover 2 is more stable.
