Description

Technical Field

[0001] This utility model relates to the field of mobile power technology, and in particular to a power bank. Background Technology

[0002] With the widespread use of mobile electronic devices, users have placed higher demands on the portability and structural simplicity of power banks. To meet these needs, a type of power bank with a built-in charging cable has emerged on the market, which doubles as a lanyard, eliminating the hassle of carrying an additional lanyard or charging cable. The specific structure is as follows: a limiting groove is formed on the side wall of the power bank body, into which the charging cable can be inserted and connected end-to-end to form a closed loop, realizing the lanyard function; when charging is needed, the charging cable can simply be removed from the limiting groove.

[0003] To further enhance ease of use, some products integrate multiple charging cables with different interface specifications (such as Lightning, Type-C, and Micro-USB) on the main body, and have corresponding storage slots on the surface of the casing to store these multiple charging cables at the same time.

[0004] However, the aforementioned limiting slots and receiving slots are all located on the side wall of the power bank body and recessed towards the center of the power bank. The slots occupy the valuable internal space of the body, which compresses the area where the battery can be placed and makes it impossible to select larger capacity battery cells. When the number, depth or width of the slots increases to accommodate more or thicker charging cables, the battery space is further squeezed, ultimately limiting the improvement of the overall energy density of the device.

[0005] Therefore, while the existing "lanyard-charging cable integration" and "multi-cable storage" designs improve portability, they also bring about a contradiction of limited battery capacity, which has become a technical problem that urgently needs to be solved. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a power bank with a hanging rope function and a charging cable that does not take up space in the main body.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a power bank, comprising:

[0008] The main body is connected to a first charging cable and a second charging cable. The end of the first charging cable away from the main body is provided with a first charging connector, and the end of the second charging cable away from the main body is provided with a second charging connector.

[0009] The mounting component is located on the first charging line and has a detachable connection structure. The second charging connector has a mating structure that mates with the detachable connection structure.

[0010] In one embodiment, the mounting component is provided with a limiting ring, one end of the first charging cable is connected to the body, the other end of the first charging cable passes through the limiting ring and is connected to the first charging connector, and the mounting component is slidable along the first charging cable.

[0011] In one embodiment, the mounting component is provided with a first magnetic attraction component, and the first charging connector is provided with a first magnetic attraction engagement component that cooperates with the first magnetic attraction component.

[0012] In one embodiment, the mounting component is provided with a first receiving groove for receiving the first charging connector.

[0013] In one embodiment, the detachable connection structure includes a snap-fit.

[0014] In one embodiment, the mating structure includes a second magnetic mating component, and the detachable connection structure includes a second magnetic component.

[0015] In one embodiment, the mounting component is provided with a second receiving groove for receiving the second charging connector.

[0016] In one embodiment, the first charging connector and the second charging connector are located on opposite sides of the mounting member.

[0017] In one embodiment, the lead-out positions of the first charging cable and the second charging cable on the body are close to each other.

[0018] In one embodiment, the type of the first charging connector may be the same as or different from the type of the second charging connector.

[0019] The beneficial effects of this utility model are as follows: This power bank, by setting an installation component with a detachable connection structure on the first charging cable and setting a matching structure on the second charging connector, allows the first and second charging cables to be directly connected end-to-end to form a closed loop outside the main body. This completely transfers the lanyard function to the charging cable itself and its connection part, eliminating the need for any recessed grooves for storage or limiting on the side wall of the power bank body. This completely avoids the problem of the battery arrangement area being compressed due to the internal space occupied by the groove, allowing for more space inside the main body to accommodate the battery cells. This creates conditions for selecting larger capacity battery cells and improving the overall energy density of the device, while retaining the portability advantage brought by the "lanyard-charging cable integration", effectively alleviating the contradiction between portability and battery capacity in the prior art.

[0038] Example 1

[0039] Please refer to Figures 1 to 4The first embodiment of this utility model is as follows: A power bank includes a body 1 and a mounting component 2. The body 1 includes a shell 11 and a battery cell and a main control board disposed within the shell 11. The battery cell and the main control board are electrically connected. The body 1 is connected to a first charging cable 3 and a second charging cable 4. The end of the first charging cable 3 away from the body 1 is provided with a first charging connector 5, and the end of the second charging cable 4 away from the body 1 is provided with a second charging connector 6. Specifically, the shell 11 is provided with a through hole 111 for the first charging cable 3 and the second charging cable 4 to pass through. The end of the first charging cable 3 away from the first charging connector 5 passes through the through hole 111 and is electrically connected to the main control board. Similarly, the end of the second charging cable 4 away from the second charging connector 6 passes through the through hole 111 and is electrically connected to the main control board. The first charging connector 5 and the second charging connector 6 are respectively used to plug into and cooperate with external electronic devices to supply power to the external electronic devices. The mounting component 2 is disposed on the first charging cable 3 and is provided with a detachable connection structure. The second charging connector 6 is provided with a mating structure that cooperates with the detachable connection structure.

[0040] In one embodiment, the mounting component 2 is provided with a limiting ring 21. One end of the first charging cable 3 is connected to the body 1, and the other end of the first charging cable 3 passes through the limiting ring 21 and is connected to the first charging connector 5. The mounting component 2 is slidable along the first charging cable 3. The slidable mounting component 2 does not affect the use of the first charging connector 5, which helps to enhance the user experience.

[0041] The mounting component 2 is provided with a first magnetic attracting component 22, and the first charging connector 5 is provided with a first magnetic engaging component that cooperates with the first magnetic attracting component 22. The magnetic engagement between the first magnetic attracting component 22 and the first magnetic engaging component allows the first charging connector 5 to remain against the mounting component 2, preventing the mounting component 2 from sliding unexpectedly relative to the first charging connector 5. When the first magnetic attracting component 22 is a magnet, the first magnetic engaging component is a magnet or an iron sheet; when the first magnetic attracting component 22 is an iron sheet, the first magnetic engaging component is a magnet.

[0042] To protect the first charging connector 5 and extend its service life, the mounting component 2 is provided with a first receiving groove 23. The first receiving groove 23 is used to receive the first charging connector 5. In this embodiment, the first magnetic suction component 22 is disposed in the first receiving groove 23.

[0043] In some embodiments, the detachable connection structure includes a buckle 24. Optionally, the buckle 24 includes two clamping arms arranged opposite each other, forming a clamping space between the two clamping arms. The clamping arms may or may not be elastic. When the clamping arms are elastic, the second charging cable 4 may be a round cable, etc. When the clamping arms are not elastic, the second charging cable 4 may be a flat cable, etc.

[0044] To better secure the mounting component 2 and the second charging connector 6, in some embodiments, the mating structure further includes a second magnetic mating component, and the detachable connection structure includes a second magnetic component 25. When the second magnetic component 25 is a magnet, the second magnetic mating component is a magnet or an iron sheet; when the second magnetic component 25 is an iron sheet, the second magnetic mating component is a magnet.

[0045] It should be noted that the first magnetic accumulator 22 and the second magnetic accumulator 25 are either the same structural component or two independent structural components. When the first magnetic accumulator 22 and the second magnetic accumulator 25 are the same structural component, they can be the same iron block or the same magnet, which can reduce the number of parts to be produced.

[0046] To protect the second charging connector 6 and extend its service life, the mounting component 2 is provided with a second receiving groove 26, which is used to receive the second charging connector 6. In this embodiment, the second magnetic member 25 is disposed in the second receiving groove 26.

[0047] Preferably, the first charging connector 5 and the second charging connector 6 are located on opposite sides of the mounting member 2. This provides a better grip for the lanyard formed by the first charging cable 3, the second charging cable 4, and the mounting member 2.

[0048] The lead-out positions of the first charging cable 3 and the second charging cable 4 on the body 1 are close to each other. In this embodiment, the first charging cable 3 and the second charging cable 4 are led out from the same through hole 111 on the outer shell 11.

[0049] The first charging connector 5 can be a Lightning connector, a Type-C connector, a Micro-USB connector, etc.; similarly, the second charging connector 6 can be a Lightning connector, a Type-C connector, a Micro-USB connector, etc.; the types of the first charging connector 5 and the second charging connector 6 can be the same or different, and can be selected and set as needed.

[0050] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
