Description

Technical Field

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

[0002] With the widespread use of mobile electronic devices, power banks, as important portable power sources, provide great convenience for people to charge their devices anytime, anywhere. Currently, many power banks on the market have a built-in charging cable structure, such as the power bank disclosed in patent document CN214154087U. These power banks with built-in charging cables typically have one end of the charging cable fixedly connected to the power bank body. At the same time, the power bank body also has a slot structure that can be embedded in the charging cable. When the charging cable is not in use, it can be stored in the slot, making the power bank more concise and neat in appearance, and convenient for users to carry when traveling.

[0003] However, in actual use, because the part of the charging cable that is fixedly connected to the power bank cannot bend freely, this fixed connection often forms an unnatural bend during charging. This unnatural bend not only affects the normal use of the charging cable but also interferes with the relative position between the phone and the power bank. For example, when a user holds the phone, this unreasonable bend may cause the phone's placement (mainly the relative position between the phone and the power bank) to be uncomfortable or unable to be adjusted to a comfortable grip angle, greatly reducing the convenience and comfort of the user when charging with the power bank. Utility Model Content

[0004] In view of this, the present invention proposes a power bank with stable winding, which aims to maintain the retractable and concealable function of the charging cable, while increasing the free bending range of the charging cable, thereby avoiding restrictions on the placement and holding angle of the mobile phone during charging.

[0005] The solution provided by this utility model includes:

[0006] A power bank with stable winding, comprising:

[0007] The power bank itself and the bidirectional charging cable;

[0008] The power bank body is provided with a winding platform, and the outer periphery of the winding platform is provided with a winding groove. The winding platform is recessed with a first clamping groove and a second clamping groove. The inner side of the first clamping groove is provided with a first opening that connects to the edge of the winding platform, and the inner side of the second clamping groove is provided with a second opening that connects to the edge of the winding platform.

[0009] The bidirectional charging cable has a first interface and a second interface at both ends. The bidirectional charging cable is wound in the winding groove, with the first interface locked in the first clamping groove and the second interface locked in the second clamping groove.

[0010] As a further optional solution, each of the two opposing inner sidewalls of the first and second wire clamping grooves is provided with a wire clamping block. The wire clamping block protrudes from the inner sidewall of the first / second wire clamping groove, and the two wire clamping blocks form a compression fit with the first / second interface clamped therein.

[0011] As a further optional solution, a guide slope is formed on the upper part of the clamping block.

[0012] As a further optional solution, both the first and second clamping grooves include a narrow section and a wide section. The clamping block is disposed in the narrow section, and the width of the wide section is at least 1.5 times the width of the first / second interface. The first / second interface is distributed in both the narrow and wide sections, and a wire-cutting space is formed in the wide section.

[0013] As a further optional solution, the power bank body is also provided with a wire-blocking protrusion, which is located on the outside of the winding groove, and the length direction of the wire-blocking protrusion is the same as the length direction of the winding groove.

[0014] As a further optional solution, the winding platform protrudes from one side of the power bank body, and a magnetic attraction part is also provided on the same side of the power bank body.

[0015] As a further optional solution, the power bank body is also provided with multiple anti-slip silicone blocks, which are distributed around the magnetic part.

[0016] As a further optional solution, the anti-slip silicone block protrudes outward by 0.5-1mm relative to the magnetic part.

[0017] As a further optional solution, the power bank itself is equipped with a power display.

[0018] Compared with existing technologies, the power bank with stable winding of this application has at least the following advantages:

[0019] Compared to existing technologies where one end of the charging cable is fixedly connected to the power bank body, the bidirectional charging cable in this application adopts a separate structure from the power bank body. This avoids the limitation imposed by a fixed connection on the bending range of the charging cable, allowing it to bend freely according to actual needs during use. When charging mobile phones or other devices, users do not need to worry about unnatural bending caused by the inability to bend the fixed connection part of the charging cable, and can adjust the direction of the charging cable more flexibly. Due to the larger bending range of the charging cable, the restrictions on the placement and holding angle of the phone during charging are significantly reduced. Users can freely adjust the position and angle of the phone according to their own usage habits and scenarios. Whether it is hand-held operation, placed on a table, or placed on a bed, it is easy to find a comfortable charging posture, greatly improving the comfort of use.

[0020] Although the bidirectional charging cable and the power bank itself are separate components, the power bank itself is equipped with a dedicated winding platform. The winding grooves on the outer periphery of the platform guide the bidirectional charging cable to wind stably. The first and second clamping grooves on the platform are used to secure the first and second interfaces of the bidirectional charging cable, respectively. Even if the power bank is shaken or squeezed during transport, the bidirectional charging cable will remain stably wound on the platform, preventing loose interfaces or the cable from scattering. This ensures both the power bank's aesthetics and ease of carrying for users. Attached Figure Description

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] refer to Figures 1 to 5This utility model discloses a power bank with stable winding, including a power bank body 1 and a bidirectional charging cable 2. The power bank body 1 is provided with a winding platform 11, and the outer periphery of the winding platform 11 is provided with a winding groove 12. The winding platform 11 is recessed with a first clamping groove 13a and a second clamping groove 13b. The inner side of the first clamping groove 13a is provided with a first opening 14a communicating with the edge of the winding platform 11, and the inner side of the second clamping groove 13b is provided with a second opening 14b communicating with the edge of the winding platform 11. The two ends of the bidirectional charging cable 2 are respectively provided with a first interface 21 and a second interface 22. The bidirectional charging cable 2 is wound in the winding groove 12, with the first interface 21 locked in the first clamping groove 13a and the second interface 22 locked in the second clamping groove 13b.

[0033] Specifically, compared to the existing technology where one end of the charging cable is fixedly connected to the power bank body, the bidirectional charging cable 2 in this application adopts a separate structure from the power bank body. This avoids the limitation imposed by a fixed connection on the bending range of the charging cable, allowing it to bend freely according to actual needs during use. When users charge mobile phones or other charging devices, they do not need to worry about unnatural bending caused by the inability to bend the fixed connection part of the charging cable, and can adjust the direction of the charging cable more flexibly. Due to the larger bending range of the charging cable, the restrictions on the placement and holding angle of the mobile phone during charging are significantly reduced. Users can freely adjust the position and angle of the mobile phone according to their own usage habits and scenarios. Whether it is hand-held operation, use on a table, or placed on a bed, it is easy to find a comfortable charging posture, greatly improving the comfort of use.

[0034] Furthermore, although the bidirectional charging cable 2 and the power bank body are separate structures, the power bank body is specially equipped with a winding platform 11. The winding groove 12 on the outer periphery of the winding platform 11 can guide the bidirectional charging cable 2 to be stably wound on it. The first clamping groove 13a and the second clamping groove 13b recessed on the winding platform 11 are used to hold the first interface 21 and the second interface 22 of the bidirectional charging cable 2, respectively. Even if the power bank is shaken or squeezed during carrying, the bidirectional charging cable 2 can be stably wound on the winding platform 11 without the problem of loose interfaces or the charging cable falling off, which not only ensures the aesthetics of the power bank, but also makes it convenient for users to carry it.

[0035] In this embodiment, the first interface 21 is a Type-C interface, and the second interface 22 is a Lightning interface. The power bank itself is also equipped with a Type-C interface and a Lightning interface. When charging an Apple phone, the first interface 21 of the bidirectional charging cable 2 can be connected to the power bank itself, and the second interface 22 can be connected to the Apple phone. When charging an Android phone, the second interface 22 of the bidirectional charging cable 2 can be connected to the power bank itself, and the first interface 21 can be connected to the Android phone. It should be noted that the charging and discharging principle of the bidirectional charging cable 2 is existing technology, such as patent document CN214314565U, and therefore will not be described in detail here.

[0036] In some embodiments, to facilitate stable clamping and fixing of the first interface 21 / second interface 22, such as Figure 2 and Figure 3 As shown, each of the two opposing inner sidewalls of the first wire clamping groove 13a and the second wire clamping groove 13b is provided with a wire clamping block 131. The wire clamping block 131 protrudes from the inner sidewall of the first wire clamping groove 13a / second wire clamping groove 13b, and the two wire clamping blocks 131 form a compression fit with the first interface 21 / second interface 22 clamped therein.

[0037] Therefore, a certain amount of external force is required to remove the first interface 21 / second interface 22 from between the two clamping blocks 131, which can effectively resist environmental factors such as shaking and squeezing that cause the bidirectional charging cable 2 to loosen.

[0038] More preferably, such as Figure 3 As shown, a guide slope 1311 is formed on the upper part of the clamping block 131. By setting the guide slope 1311, when the first interface 21 / second interface 22 is engaged with the two clamping blocks 131, it gradually tightens from loose to tight, making it easier for the first interface 21 / second interface 22 to engage between the two clamping blocks 131.

[0039] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the first wire clamping groove 13a and the second wire clamping groove 13b both include a narrow section and a wide section. The wire clamping block 131 is disposed in the narrow section. The width of the wide section is at least 1.5 times the width of the first interface 21 / second interface 22. The first interface 21 / second interface 22 are distributed in both the narrow section and the wide section. A wire cutting space is formed in the wide section.

[0040] The cut-out space is formed by the extra space beyond the first interface 21 / second interface 22, which is contained in the wide section. A finger can be inserted into the cut-out space to dig out the first interface 21 / second interface 22. In this way, even when the two clamping blocks 131 are clamping the first interface 21 / second interface 22, the bidirectional charging cable 2 can be easily removed.

[0041] In addition, to further improve the stability of the bidirectional charging cable 2 within the winding groove 12, such as Figure 2 and Figure 4 As shown, the power bank body 1 is also provided with a wire-blocking protrusion 15. The wire-blocking protrusion 15 is located on the outside of the winding groove 12, and the length direction of the wire-blocking protrusion 15 is the same as the length direction of the winding groove 12. In this way, the wire-blocking protrusion 15 can prevent the bidirectional charging cable 2 from leaving the winding groove 12, requiring a certain pulling force to remove the bidirectional charging cable 2, thus improving the winding stability of the bidirectional charging cable 2 on the winding platform 11.

[0042] In some embodiments, such as Figure 1 As shown, the winding platform 11 protrudes from one side of the power bank body, and a magnetic suction part 16 is also provided on the same side of the power bank body. Thus, the magnetic suction part 16 can be used to attach the phone to the back of the device, making it convenient to carry the phone and power bank together.

[0043] The above-mentioned solutions are specific, such as Figure 1 and Figure 5 As shown, the power bank body is also provided with multiple anti-slip silicone blocks 17, which are distributed around the magnetic part 16. Thus, when the magnetic part 16 attracts a mobile phone, the phone contacts the anti-slip silicone blocks 17, improving the positional stability between the phone and the power bank body.

[0044] Preferably, the anti-slip silicone block 17 protrudes outward relative to the magnetic suction part 16 by 0.5-1mm. This ensures that the mobile phone only contacts the anti-slip silicone block 17 and avoids unstable adhesion caused by the magnetic suction part 16 being too far away from the mobile phone.

[0045] In some embodiments, such as Figure 1 As shown, the power bank itself is equipped with a power display 18. The power display 18 can show the remaining power of the power bank for user convenience.

[0046] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
