Some existing power banks come with a built-in data cable to meet user needs and reduce the inconvenience of carrying multiple items. However, the storage of the built-in data cable in these power banks is not smooth, often resulting in jamming during storage. Furthermore, the data cable does not automatically retract into the power bank after use, thus affecting portability. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a power bank with a pull-out cable, which solves the problem of unsmooth data cable storage in existing power banks.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A portable power bank with a pull-out cord includes a housing, a pull-out cord mechanism, and a guide mechanism. The pull-out cord mechanism and the guide mechanism are both disposed within the housing. One end of the pull-out cord mechanism extends through the guide mechanism to the outside of the housing. In use, the pull-out cord mechanism changes its path under the action of the guide mechanism, making the pull-out cord mechanism smoother to use.

[0006] In the above scheme, the pull-out cord mechanism includes a pull-out cord body, a cord box, and a cord plate. The cord box is disposed inside the outer shell. One end of the pull-out cord body is connected to the cord box, and the other end extends out of the outer shell through the guide mechanism. The cord plate is disposed on the cord box, and the pull-out cord body is also connected to the cord plate.

[0007] In the above solution, the guiding mechanism includes at least two guide posts, both of which are disposed within the housing; and a channel is formed between the at least two guide posts for the pull-out cord body to pass through.

[0008] In the above scheme, the guide post is made of Teflon.

[0009] In the above solution, the power bank also includes an adsorption mechanism, and one end of the pull cord extends to the outer shell and is connected to the outer shell through the adsorption mechanism; in use, the adsorption mechanism makes the pull cord automatically adhere to the outer shell.

[0010] In the above scheme, the adsorption mechanism includes a first adsorption element and a second adsorption element. The first adsorption element is disposed in the outer shell, and the second adsorption element is disposed in the pull cord. The first adsorption element and the second adsorption element are connected in cooperation, so that one end of the pull cord body is adsorbed to the outer shell.

[0011] In the above scheme, the outer casing is provided with a cable outlet, and at least two guide posts are disposed inside the cable outlet.

[0012] In the above solution, the outer shell is also provided with a groove for accommodating the pull-out cord body.

[0013] In the above solution, the power bank also includes a control mechanism, which is disposed inside the housing and connected to the circuit board.

[0025] Example

[0026] This utility model provides a portable power bank with a pull-out cord. See also: Figures 1 to 5 It includes an outer shell 1, a pull-out cord mechanism 2, and a guide mechanism 3. Both the pull-out cord mechanism 2 and the guide mechanism 3 are located inside the outer shell 1. One end of the pull-out cord mechanism 2 extends through the guide mechanism 3 to the outside of the outer shell 1. In use, the pull-out cord mechanism 2 changes its path under the action of the guide mechanism 3, making the pull-out cord mechanism 2 smoother to use.

[0027] By adopting the above solution, this utility model changes the path of the pull-out cord mechanism 2 by extending one end of the pull-out cord mechanism 2 through the guide mechanism 3 to the outside of the outer shell 1, making the pull-out cord mechanism 2 easier to retract or unfold. This utility model has a simple structure, smooth retraction, small size, and low cost, making it worth using.

[0028] See Figures 1 to 3In a specific implementation of this utility model embodiment, the pull-out cord mechanism 2 further includes a pull-out cord body 21, a cord box 22, and a cord plate 23. The cord box 22 is disposed inside the outer casing 1.

The cord plate 23 is disposed on the cord box 22, and the pull-out cord body 21 is also connected to the cord plate 23. The pull-out cord body 21 is used to transmit current to external devices; the cord box 22 is used to wind and store the pull-out cord body 21; and the cord plate 23 is used to provide current to the pull-out cord body 21.

[0029] In a specific implementation of this utility model embodiment, a connector is further provided at one end of the pull-out cord body 21 that extends outside the outer shell 1, and the connector is a Type-C interface.

[0030] In a specific implementation of this utility model embodiment, an elastic element is further provided inside the cable box 22, which provides elastic force when the cable body 21 is pulled back.

[0031] See Figure 4 In a specific implementation of this utility model embodiment, the guiding mechanism 3 further includes at least two guide posts 31, both of which are disposed inside the outer shell 1; and a channel is formed between the at least two guide posts 31 for the pull-out cord body 21 to pass through.

[0032] Furthermore, in this embodiment of the invention, the guide post 31 is configured as two.

[0033] In a specific implementation of this utility model embodiment, the guide post 31 is further made of Teflon. The guide post 31 has a low surface friction coefficient, strong wear resistance, and can fully meet the actual service life requirements, exhibiting stable performance.

[0034] See Figure 2 In a specific implementation of this utility model embodiment, the power bank further includes an adsorption mechanism 4. One end of the pull-out cord body 21 extends to the outer shell 1 and is connected to the outer shell 1 through the adsorption mechanism 4. In use, the adsorption mechanism 4 enables the pull-out cord body 21 to automatically adhere to the outer shell 1.

[0035] Furthermore, the adsorption mechanism 4 includes a first adsorption element 41 and a second adsorption element 42. The first adsorption element 41 is disposed inside the outer shell 1, and the second adsorption element 42 is disposed inside the pull cord body 21. The first adsorption element 41 and the second adsorption element 42 are connected in cooperation, thereby causing one end of the pull cord body 21 to be adsorbed by the outer shell 1.

[0036] Furthermore, in this embodiment of the present invention, both the first adsorption element 41 and the second adsorption element 42 are magnets.

[0037] In a specific implementation of this utility model embodiment, the outer casing 1 is further provided with a cable outlet 11, and at least two guide posts 31 are disposed within the cable outlet 11. The cable outlet 11 is used to provide an outlet for the pull-out cable body 21.

[0038] See Figure 1 and Figure 2 In a specific implementation of this utility model embodiment, the outer shell 1 is further provided with a groove 12 for accommodating the pull-out cord body 21.

[0039] See Figure 1 In a further embodiment of this utility model, the power bank also includes a control mechanism 5, which is disposed inside the outer casing 1 and connected to the circuit board 23. The control mechanism 5 serves as the main control board of the power bank.

[0040] See Figure 1 In a further embodiment of this utility model, the portable power supply also includes a power supply mechanism 6, which is disposed inside the outer casing 1 and connected to the cable board 23 via a control mechanism 5. The power supply mechanism 6 provides power to the pull-out cable body 21 and the control mechanism 5.

[0041] See Figure 1 and Figure 5 In a further embodiment of this utility model, the outer casing 1 is also provided with a pin 13, which is connected to the power supply mechanism 6. The pin 13 is used to provide power to the power supply mechanism 6, enabling the power supply mechanism 6 to store electricity.

[0042] In a specific implementation of this embodiment, a display screen is further provided on the outer casing 1. The display screen is used to display information such as battery level.

[0043] The working process of a portable power bank with a pull-out cord provided in this embodiment of the utility model is as follows:

[0044] See Figures 1 to 5 First, the user removes the pull-out cable body 21 from the groove 12, and the first suction member 41 separates from the second suction member 42. At this time, the pull-out cable body 21 is pulled out from the cable box 22 and changes its path under the action of the guide post 31. Finally, the connector on the pull-out cable body 21 is connected to the external device to complete the cable retrieval and charging process.

[0045] Next, release the pull-out cord body 21, and the cord box 22 will retract the pull-out cord body 21. At the same time, under the action of the guide post 31, the path will be changed. When the connector of the pull-out cord body 21 is located at the groove 12, the first adsorption member 41 and the second adsorption member 42 will adsorb each other, so that the pull-out cord body 21 fits into the outer shell 1, completing the storage process.

[0046] In summary, this invention changes the path of the pull-out cord body 21 by passing one end of the pull-out cord body 21 through the channel between the two guide posts 31 and extending it to the outside of the outer shell 1, making the retraction and unfolding of the pull-out cord body 21 smoother. Simultaneously, this invention connects one end of the pull-out cord body 21 to the outer shell 1 via an adsorption mechanism 4, allowing the pull-out cord body 21 to automatically conform to the outer shell 1. This invention achieves smooth extension and retraction of the pull-out cord body 21 by utilizing the cord box 22. This invention has a simple structure, smooth retraction, small size, and low cost, making it worthy of use.
