[0022] This application provides a mobile charging device; please refer to [link / reference]. Figure 1 The mobile charging device includes a power source 10 and at least two data cables 20.

[0023] Specifically, at least two data cables 20 have one end electrically connected to the power supply 10. The other end of the data cables 20 is used for electrical connection to the charging port of the electronic device. By providing multiple data cables 20, the mobile charging device can charge electronic devices with different charging ports.

[0024] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 The mobile charging device includes a first protective sleeve 30 and a second protective sleeve 40, which are respectively sleeved on two data cables 20. The first protective sleeve 30 and the second protective sleeve 40 are rotatably connected separately.

[0025] For ease of description, the data cable 20 with the first protective sleeve 30 is named the first data cable 20a, and the data cable 20 with the second protective sleeve 40 is named the second data cable 20b. That is, at least two data cables 20 include the first data cable 20a and the second data cable 20b.

[0026] Thus, when the first protective sleeve 30 and the second protective sleeve 40 are separated, the first data cable 20a and the second data cable 20b can charge different electronic devices respectively; when the first protective sleeve 30 and the second protective sleeve 40 are connected, at least a portion of the first data cable 20a, at least a portion of the second data cable 20b, and the power supply 10 form a closed ring structure. This ring structure can be suspended by the user, for example, by hanging it on the hand, arm, clothing, or backpack, which helps to improve the portability of the mobile charging device. Moreover, the first protective sleeve 30 and the second protective sleeve 40 can rotate relative to each other, which facilitates the adjustment of the angle between the first data cable 20a and the second data cable 20b. On the one hand, this allows the ring structure to adapt to different hanging objects; on the other hand, when the ring structure is in the hanging state, it can dynamically adjust the tension on the first data cable 20a and the second data cable 20b, which helps to reduce stress concentration on the first data cable 20a and the second data cable 20b.

[0027] In some embodiments, the rotational stroke of the second protective sleeve 40 relative to the first protective sleeve 30 does not exceed 120°. That is, the included angle α between the second protective sleeve 40 and the first protective sleeve 30 does not exceed 120°, i.e., α ≤ 120°. Thus, when the ring structure is suspended, controlling the included angle between the first protective sleeve 30 and the second protective sleeve 40 helps to control the rotation amplitude between the first data cable 20a and the second data cable 20b, reducing the probability that the first data cable 20a and the second data cable 20b will be bent and damaged due to excessive rotation amplitude.

[0028] In some embodiments, please refer to Figure 2 , Figure 4 , Figure 6 The first protective sleeve 30 includes a first protective sleeve body 31 and a sleeve 32 connected to each other. The second protective sleeve 40 includes a second protective sleeve body 41 and a rotating member 42 connected to each other. The rotating member 42 is rotatably disposed in the sleeve 32 so that the second protective sleeve body 41 rotates relative to the first protective sleeve body 31.

[0029] The rotational stroke of the second protective sleeve 40 relative to the first protective sleeve 30 does not exceed 120°, which means that the rotational stroke of the rotating part 42 within the sleeve 32 does not exceed 120°, so that the rotational stroke of the second protective sleeve body 41 relative to the first protective sleeve body 31 does not exceed 120°, that is, the included angle α between the second protective sleeve body 41 and the first protective sleeve body 31 does not exceed 120°.

[0030] In this embodiment, the first protective sleeve body 31 and the second protective sleeve body 41 are respectively sleeved on the corresponding data lines 20, that is, the first protective sleeve body 31 is sleeved on the first data line 20a, and the second protective sleeve body 41 is sleeved on the second data line 20b. The sleeve 32 provides rotation space for the rotating component 42.

[0031] For example, the sleeve 32 is a cylindrical structure with an opening at one end, allowing the rotating member 42 to enter and exit, thereby enabling the sleeve 32 and the rotating member 42 to be separable. In this embodiment, the other end of the sleeve 32 can position the rotating member 42 along the axial direction of the sleeve 32 when the rotating member 42 enters the sleeve 32.

[0032] It is understood that in other embodiments, both ends of the sleeve 32 may have openings.

[0033] For example, the sleeve 32 and the first protective sleeve body 31 are integrally formed. This helps to increase the connection stability between the sleeve 32 and the first protective sleeve body 31, and also helps to reduce the assembly between the sleeve 32 and the first protective sleeve body 31.

[0034] For example, the rotating component 42 and the second protective sleeve body 41 are integrally formed. This helps to increase the connection stability between the rotating component 42 and the second protective sleeve body 41, and also helps to reduce the assembly between the rotating component 42 and the second protective sleeve body 41.

[0035] In some embodiments, the first protective sleeve body 31 has a first side wall 311, the sleeve 32 is disposed on the first side wall 311, the second protective sleeve body 41 has a second side wall 411, the rotating member 42 is disposed on the second side wall 411, and the first side wall 311 and the second side wall 411 are always disposed opposite to each other.

[0036] In this embodiment, since the first sidewall 311 and the second sidewall 411 are always arranged opposite each other, it means that the included angle between the first sidewall 311 and the second sidewall 411 is always less than 180°. When the rotating member 42 is located inside the sleeve 32, the sleeve 32 is located between the first sidewall 311 and the second sidewall 411.

[0037] Moreover, the first sidewall 311 provides sufficient mounting area for the sleeve 32, and the second sidewall 411 provides sufficient mounting area for the rotating part 42.

[0038] For example, one end of the rotating member 42 is formed with a limiting portion 422. When at least a portion of the rotating member 42 is disposed inside the sleeve 32, the limiting portion 422 is located outside the sleeve 32. When the rotating member 42 rotates to its limit position, the limiting portion 422 abuts against the first sidewall 311. In this way, the rotational stroke of the rotating member 42 within the sleeve 32 is limited by the limiting portion 422, thereby controlling the rotational stroke of the second protective sleeve body 41 relative to the first protective sleeve body 31.

[0039] In some embodiments, the sleeve 32 is located at the end of the first protective sleeve body 31 away from the power source 10. That is, the sleeve 32 is located at the end of the first sidewall 311 away from the power source 10. When the length of the data cable 20 is limited, this helps to increase the ring size of the ring structure, allowing the ring structure to accommodate more hanging objects.

[0040] In some embodiments, the rotating member 42 is located at the end of the second protective sleeve body 41 away from the power source 10. That is, the rotating member 42 is located at the end of the second sidewall 411 away from the power source 10. When the length of the data cable 20 is limited, this helps to increase the ring size of the ring structure, allowing the ring structure to accommodate more hanging objects.

[0041] In some embodiments, the first protective sleeve 30 includes a first magnetic element 33 disposed within the sleeve 32, and the second protective sleeve 40 includes a second magnetic element 43 disposed within the rotating member 42. When the rotating member 42 is disposed within the sleeve 32, the first magnetic element 33 and the second magnetic element 43 magnetically engage. This magnetic engagement between the first magnetic element 33 and the second magnetic element 43 helps increase the stability of the rotating member 42 within the sleeve 32, reducing the likelihood of the first protective sleeve 30 and the second protective sleeve 40 separating when the mobile charging device is in a suspended state. It also allows the rotating member 42 to separate from the sleeve 32.

[0042] For example, such as Figure 6 As shown, the sleeve 32 has a first end 321 and a second end 322 along its extending direction. The first end 321 has a first opening 3211 for the rotating member 42 to enter and exit. The first magnetic member 33 is located at the second end 322. Figure 8 As shown, the rotating member 42 is cylindrical, and a second opening 421 is formed at one end of the rotating member 42. When the rotating member 42 is disposed inside the sleeve 32, the second opening 421 is away from the second end 322. The second magnetic member 43 is disposed inside the rotating member 42 and at the end of the rotating member 42 away from the second opening 421.

[0043] In this embodiment, when the rotating member 42 is disposed within the sleeve 32, the first magnetic member 33 and the second magnetic member 43 are magnetically attracted to each other along the axial direction of the sleeve 32. The first magnetic member 33 is installed into the sleeve 32 through the first opening 3211, and the second end 322 is used to limit the first magnetic member 33, so that the first magnetic member 33 can be stably located within the sleeve 32. The second opening 421 is used to allow the second magnetic member 43 to be installed into the rotating member 42, and the end of the rotating member 42 away from the second opening 421 limits the second magnetic member 43, so that the second magnetic member 43 can be stably located inside the rotating member 42.

[0044] For example, such as Figure 6As shown, the first magnetic element 33 and / or the second magnetic element 43 are columnar.

[0045] In some embodiments, such as Figure 5 As shown, the data cable 20 includes interconnected cable bodies 21 and plug-in parts 22, which are used for electrical connection with the charging port of an electronic device.

[0046] For example, a first protective sleeve 30 is fitted onto a first data cable 20a and can slide along the body 21 of the first data cable 20a. The insertion portion 22 of the first data cable 20a forms a limit on the first protective sleeve 30. A second protective sleeve 40 is fitted onto a second data cable 20b and can slide along the body 21 of the second data cable 20b. The insertion portion 22 of the second data cable 20b forms a limit on the second protective sleeve 40.

[0047] In this embodiment, when it is necessary to suspend the mobile charging device, the first protective sleeve 30 slides to the plug portion 22 of the first data cable 20a, and the second protective sleeve 40 slides to the plug portion 22 of the second data cable 20b. When the length of the data cable 20 is limited, this helps to increase the ring size of the ring structure.

[0048] For example, the first protective sleeve 30 has a first mounting hole 312 and a second mounting hole 313 that are interconnected. The wire 21 of the first data cable 20a passes through the first mounting hole 312 and the second mounting hole 313. The first mounting hole 312 is located on the side of the second mounting hole 313 away from the plug portion 22 of the first data cable 20a. In the orthographic projection of a plane perpendicular to the extension direction of the first mounting hole 312, the projection of the first mounting hole 312 is at least partially located within the projection of the plug portion 22 of the first data cable 20a, and the projection of the plug portion 22 of the first data cable 20a is located within the projection of the second mounting hole 313.

[0049] The projection of the plug portion 22 of the first data cable 20a is located within the projection of the second mounting hole 313, that is, the plug portion 22 of the first data cable 20a can pass through the second mounting hole 313, so that the plug portion 22 of the first data cable 20a is located within the first protective sleeve 30 (e.g., Figure 4 (As shown).

[0050] The projection of the first mounting hole 312 is at least partially located within the projection of the plug portion 22 of the first data line 20a, that is, the plug portion 22 of the first data line 20a cannot pass through the first mounting hole 312, thereby limiting the first protective sleeve 30.

[0051] Thus, when the mobile charging device is suspended, the first protective sleeve 30 is stably fitted onto the first data cable 20a, and the first protective sleeve 30 can protect the plug portion 22 of the first data cable 20a. Simultaneously, the first protective sleeve 30 is positioned as far as possible from the power source end of the first data cable 20a to maximize the ring size of the annular structure. When the first data cable 20a is needed to charge the electronic device, simply separate the first protective sleeve 30 and the second protective sleeve 40, and slide the first protective sleeve 30 along the cable body 21 of the first data cable 20a towards the power source 10, exposing the plug portion 22 of the first data cable 20a (e.g., ...). Figure 5 (As shown).

[0052] For example, the second protective sleeve 40 is formed with a third mounting hole 412 and a fourth mounting hole 413 that are interconnected. The wire 21 of the second data cable 20b passes through the third mounting hole 412 and the fourth mounting hole 413. The third mounting hole 412 is located on the side of the fourth mounting hole 413 away from the plug portion 22 of the second data cable 20b. In the orthographic projection of a plane perpendicular to the extending direction of the third mounting hole 412, the projection of the third mounting hole 412 is at least partially located within the projection of the plug portion 22 of the second data cable 20b, and the projection of the plug portion 22 of the second data cable 20b is located within the projection of the fourth mounting hole 413.

[0053] The projection of the plug portion 22 of the second data cable 20b is located within the projection of the fourth mounting hole 413, that is, the plug portion 22 of the second data cable 20b can pass through the fourth mounting hole 413, so that the plug portion 22 of the second data cable 20b is located within the second protective sleeve 40 (e.g., Figure 4 (As shown).

[0054] The projection of the third mounting hole 412 is at least partially located within the projection of the plug portion 22 of the second data cable 20b, meaning that the plug portion 22 of the second data cable 20b cannot pass through the third mounting hole 412, thereby limiting the second protective sleeve 40.

[0055] Thus, when the mobile charging device is suspended, the second protective sleeve 40 is stably fitted onto the second data cable 20b, and the second protective sleeve 40 can protect the plug portion 22 of the second data cable 20b. Simultaneously, the second protective sleeve 40 is positioned as far as possible at the end of the second data cable 20b away from the power source 10, thereby maximizing the ring size of the annular structure. When the second data cable 20b is needed to charge the electronic device, simply separate the first protective sleeve 30 and the second protective sleeve 40, and slide the second protective sleeve 40 along the cable body 21 of the second data cable 20b towards the power source 10, exposing the plug portion 22 of the second data cable 20b (e.g., ...). Figure 5 (As shown).
