Description

Technical Field

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

[0002] To better connect with 3C digital devices, many portable power banks on the market now come with built-in charging cables. Some even have charging cables that can be folded up and used as a handle. The cable can be fully extended to power phones and other devices when needed, and folded away to serve as a handle when not in use. However, many users still prefer an extremely small size and a better feel, hoping the charging cable can be completely stored away when not in use. Currently, power banks with handles generally cannot completely retract the charging cable into the body; their storage methods are relatively limited and cannot meet the needs of users in specific usage scenarios. Utility Model Content

[0003] The purpose of this invention is to provide a portable power bank device. This invention offers multiple storage options to accommodate different usage scenarios and meet the diverse needs of users.

[0004] The technical solution of this utility model is as follows: A mobile power supply device includes a device body and a charging cable. One end of the charging cable is connected to the device body, and the other end is provided with a charging head. The device body is provided with a first storage part and a second storage part, both of which are adapted to store the charging head. When the charging head is stored in the first storage part, the charging cable is fully stored on the device body in a relatively taut state. When the charging head is stored in the second storage part, the charging cable forms a first handle that can be lifted in a relatively slack state.

[0005] Compared with existing technologies, the advantages of this invention are as follows: This invention features two storage sections on the device body, both of which can be used to store the charging head of the charging cable, allowing for diversified storage according to user needs. Specifically, when the charging head is stored in the first storage section, the charging cable is taut and fully stored on the device body, resulting in a very small overall size of the power bank, providing a good grip and easy storage. Furthermore, in this state, the power bank is less prone to cable tangling when used with other devices. When the charging head is stored in the second storage section, the charging cable is looser, forming a first handle for lifting. Users can then lift and carry the power bank using this handle. Additionally, the power bank can also be suspended using the first handle. In summary, by providing two storage sections, this invention offers diversified charging cable storage to meet the needs of various usage scenarios.

[0006] In the aforementioned power bank device, when the charging cable is fully retracted into the device body, the charging cable forms a retraction path from one end to the other, and the second retraction part is located on the retraction path.

[0007] In the aforementioned portable power bank device, the first storage section is located at the end of the storage path.

[0008] In the aforementioned power bank device, the second storage section is closer to the end of the charging cable that connects to the device body than the first storage section.

[0009] In the aforementioned power bank device, the device body is provided with a storage slot. When the charging head is stored in the first storage part, the charging cable is stored along the storage slot.

[0010] In the aforementioned power bank device, a retaining ring is connected to the device body, and the charging cable passes through the retaining ring.

[0011] In the aforementioned power bank device, the retaining ring is positioned adjacent to the second storage section, and when the charging head is stored in the second storage section, there is no contact between the retaining ring and the charging head.

[0012] In the aforementioned power bank device, the retaining ring can limit the charging head. When the charging head is not stored in the second storage part, the retaining ring can be used to hold the charging head, so that the charging cable forms a second handle that can be lifted in a relatively loose state.

[0013] In the aforementioned portable power supply device, the device body is provided with a tool discharge terminal, which is adapted to be connected to a corresponding terminal on a power tool.

[0014] In the aforementioned power bank device, the charging head includes a USB interface. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] This utility model embodiment provides a mobile power supply device, the structure of which is as follows: Figures 1 to 4As shown, the device includes a device body 1 and a charging cable 2. One end of the charging cable 2 is connected to the device body 1, and the other end is provided with a charging head 3. The device body 1 is provided with a first storage part 11 and a second storage part 12. Both the first storage part 11 and the second storage part 12 are suitable for storing the charging head 3. When the charging head 3 is stored in the first storage part 11, the charging cable 2 is completely stored on the device body 1 in a relatively taut state. When the charging head 3 is stored in the second storage part 12, the charging cable 2 forms a first handle part 20 that can be lifted in a relatively slack state. The first storage part 11 and the second storage part 12 are both concave grooves.

[0027] Specifically, the charging head 3 includes an interface that connects to 3C digital devices, and a cover that is wrapped around the interface and can be held by the user. The cover is larger than the interface and can be made of materials such as rubber, silicone, or metal.

[0028] The charging cable 2 can be completely stored on the device body 1 in a relatively taut state. This can be because the charging cable 2 and the device body 1 are completely attached to each other, and there is no movable gap between the charging cable 2 and the device body 1. Alternatively, there can be a small movable gap between the charging cable 2 and the device body 1, but this gap is so small that the charging cable 2 cannot be locally coiled to form a handle-like structure.

[0029] The charging cable 2 is in a relatively loose state to form a first handle 20 that can be pulled up. This can be understood as the charging cable 2 being partially wound to form a first handle 20 that is similar to a handle loop. The first handle 20 can be inserted into at least the fingers of an adult.

[0030] Optionally, the device body 1 is provided with a tool discharge terminal 14, which is adapted to be connected to the corresponding terminal on the power tool. The power tool includes common electric drills, electric wrenches, electric screwdrivers, etc., as well as lawnmowers, snow sweepers, etc. used in garden scenes. As long as the terminal on the power tool can be matched with the tool discharge terminal 14 on the device body 1, the mobile power supply device of this embodiment can be used to supply power to it.

[0031] In this embodiment, the mobile power supply device, through the addition of the tool discharge terminal 14, becomes a universal power supply device in the fields of power tools and 3C digital products, with a wide range of application scenarios.

[0032] Optionally, when the charging cable 2 is completely stored on the device body 1, the charging cable 2 forms a storage path from one end to the other. The second storage part 12 is located on the storage path. The storage path is set along the surface of the device body 1 and can be a groove or a buckle or other structure, as long as it can restrict the charging cable 2 to a certain extent and arrange it along a fixed path.

[0033] In this embodiment, the storage path is designed so that the charging cable 2 can be arranged along a fixed path when fully stored, making it neat and aesthetically pleasing. By setting the second storage part 12 on the storage path, when the charging head 3 is stored in the second storage part 12, that is, when the charging cable 2 is used as a handle, part of the charging cable 2 can still be fixed by the slots or buckles on the storage path.

[0034] Optionally, the first storage part 11 is located at the end of the storage path, that is, the starting end of the charging cable 2, the second storage part 12 and the first storage part 11 are respectively arranged on the device body 1 along the storage path; wherein, the starting end of the charging cable 2 is electrically connected to the internal circuit board of the device body 1, and the connection between the starting end and the device body 1 can be set as a fixed connection or as a detachable connection through a quick connector.

[0035] In this embodiment, the first storage part 11 is set at the end of the storage path, which fully considers that when the power bank device completely stores the charging cable 2, its outer surface will no longer expose the grooves or buckles on the storage path, nor will it expose the second storage part 12, making the appearance more concise and beautiful.

[0036] Optionally, the second storage section 12 is closer to the end of the charging cable 2 that connects to the device body 1 than the first storage section 11. Here, "closer" should be understood as the first storage section 11 being located at the end of the storage path, while the second storage section 12 is located at a certain position between the beginning and end of the storage path, rather than being closer in a straight line. In a straight line, the second storage section 12 may be closer to the end of the charging cable 2 that connects to the device body 1 than the first storage section 11, or the first storage section 11 may be closer to the end of the charging cable 2 that connects to the device body 1 than the second storage section 12.

[0037] In this embodiment, the second storage part 12 is located closer to the end of the charging cable 2 that connects to the device body 1 than the first storage part 11. Firstly, when the charging head 3 is stored in the second storage part 12, the charging cable 2 can have sufficient slack to wind and form the first handle part 20. Secondly, when the charging cable 2 is fully stored, the charging cable 2 can cover the second storage part 12 and prevent it from being exposed, making the appearance simpler and more beautiful.

[0038] Optionally, the device body 1 is provided with a storage slot 13. When the charging head 3 is stored in the first storage part 11, the charging cable 2 is stored along the storage slot 13. The storage slot 13 can be a continuous slot or several slots arranged along the storage path. The size of the storage slot 13 matches the wire diameter of the charging cable 2. Generally speaking, after the charging cable 2 is stored in the storage slot 13, there is still a small movable gap around the charging cable 2.

[0039] The second storage part 12 is located at the bottom of the storage groove 13. Since the size of the charging head 3 is definitely larger than the diameter of the charging cable 2, a deeper recess needs to be provided at the location of the storage groove 13 corresponding to the second storage part 12.

[0040] In this embodiment, the storage slot 13 allows the charging cable 2 to be embedded in the outer surface of the device body 1 when fully stored, making the power bank device look more concise and aesthetically pleasing.

[0041] In addition, since this embodiment is a power supply device applicable to both the power tool and 3C digital fields, when this embodiment is applied to the power tool field, the charging cable 2 is completely stored in the storage slot 13, and the problem of wire harness tangling is not easily caused when connecting it to the power tool, which makes the corresponding power tool safer and more reliable to use.

[0042] Optionally, a retaining ring 4 is connected to the device body 1, and the charging cable 2 passes through the retaining ring 4. The device body 1 includes an upper shell 15 and a lower shell 16. The retaining ring 4 is connected to the upper shell 15, and can be fixedly connected or detachably connected to the upper shell 15.

[0043] In this embodiment, the setting of the retaining ring 4 adds an extra storage point to the charging cable 2 on the storage path, which can limit and guide the charging cable 2, making it easier to store the charging cable 2.

[0044] Optionally, the retaining ring 4 is positioned adjacent to the second storage section 12, and when the charging head 3 is stored in the second storage section 12, there is no contact between the retaining ring 4 and the charging head 3.

[0045] In this embodiment, when the charging head 3 is normally stored in the second storage part 12, the retaining ring 4 is not subject to the force of the charging head 3, and there is only a force between it and the charging cable 2.

[0046] Optionally, the retaining ring 4 can limit the charging head 3. When the charging head 3 is not stored in the second storage part 12, the retaining ring 4 can be used to hold the charging head 3, so that the charging cable 2 forms a second handle that can be lifted in a relatively loose state. The second handle is the same as the first handle 20, and is a ring-shaped handle.

[0047] In this embodiment, when the charging head 3 is not inserted into the second storage part 12 and the charging head 3 directly acts on the retaining ring 4, the retaining ring 4 can hold the charging head 3 in place, and the charging cable 2 can also form a loop handle. This situation applies when the charging head 3 slides out of the second storage part 12, and the retaining ring 4 can play a secondary protection role.

[0048] In this embodiment, please refer to Figures 5 to 7The provided retaining ring 4 is a structure that is fixed to the upper housing 15. It includes a first ring body 41a in a circular closed shape and a first extension 42a connected to the first ring body 41a. The first extension 42a is inserted into the interior of the upper housing 15 and is fixedly connected to the upper housing 15 inside the upper housing 15 by screws.

[0049] In another implementation, please refer to Figures 8 to 9 The provided retaining ring 4 is a structure that can be detachably connected to the upper housing 15. It includes a ring-shaped open second ring body 41b, with a second extension 42b connected to each of the open ends of the second ring body 41b. The end of the second extension 42b is provided with a boss for locking. The second extension 42b can be inserted into the interior of the upper housing 15. The interior of the upper housing 15 is provided with a groove that matches the boss. When the second extension 42b is inserted into the interior of the upper housing 15 and the boss engages with the groove, the retaining ring 4 is installed. When the retaining ring 4 needs to be removed, the two second extensions 42b are pinched together in a direction perpendicular to the second extension 42b. When the boss disengages from the groove, the retaining ring 4 can be pulled out.

[0050] Optionally, the charging head 3 includes a USB interface, specifically a USB Type-C interface.

[0051] In this embodiment, a TYPE-C interface is provided to be compatible with the input interfaces of most 3C digital devices currently on the market.

[0052] Optionally, the device body 1 also has a TYPE-C interface, which is located on the storage path of the charging cable 2. The TYPE-C interface is a bidirectional input / output structure. When the charging cable 2 is completely stored, the charging cable 2 can cover the TYPE-C interface.

[0053] Optionally, the first storage section 11 and the second storage section 12 may have the same or different structures, see reference. Figure 1 and Figure 2 In this embodiment, the first storage part 11 and the second storage part 12 have the same structure.

[0054] In another embodiment, the first storage part 11 and the second storage part 12 have different structures. Specifically, the structure of the first storage part 11 is configured such that the charging head 3 can be horizontally embedded (see reference). Figure 2 The structure of the second storage part 12 is configured such that the charging head 3 can be vertically embedded (not shown in the figure). That is, the TYPE-C interface of the charging head 3 is vertically embedded into the second storage part 12 for fixation in a non-powered manner. In this embodiment, the setting of the retaining ring 4 can be eliminated. When the charging head 3 is vertically embedded into the second storage part 12, the charging cable 2 can form a handle for use.
