Description

Technical Field

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

[0002] To improve portability, some power banks now feature charging cables that can be used as lanyards. For example, the power bank shown in patent document CN218124344U has a charging cable with one end fixed to the circuit board inside the power bank and the other end extending outside. A limiting groove is formed by an inward indentation on the outer wall of the power bank, and a limiting opening is formed on the side wall of the limiting groove. The charging cable passes through the limiting opening, but the connector on the charging cable cannot pass through the limiting opening. When charging is needed, the connector can be pulled out of the limiting groove. However, the above structure... Figure 1 As shown, even when the connector is pulled outwards, the length (L) of the charging cable from the point where it exits the power bank to the limiting opening cannot be utilized, resulting in wasted length and also affecting the degree of freedom of the charging cable when bending and swinging to some extent. Therefore, improvements are needed. Utility Model Content

[0003] In view of this, this utility model proposes a portable power bank, which aims to improve the utilization rate of the charging cable while taking into account the stability of the charging cable when used as a lanyard.

[0004] The solution provided by this utility model includes:

[0005] A portable power bank includes a power bank body and a charging cable. One end of the charging cable is fixedly connected to a circuit board inside the power bank body, and the other end of the cable is connected to a connector.

[0006] The power bank body is equipped with a cable threading hole and a cable clamping groove;

[0007] The cable threading hole is provided through the thickness direction of the outer wall of the power bank body so that the charging cable can pass through to the outside of the power bank body;

[0008] The cable slot is recessed on the outer surface of the power bank body. The cable slot includes a placement section, a locking section, and a cable passage section along its length. The placement section and the locking section are for placing the connector, and the cable passage section is for placing the charging cable. The locking section is provided with a blocking part to prevent the connector from leaving the depth direction of the cable slot. A blocking step is formed between the locking section and the cable passage section, and the blocking step is used to abut against one end of the connector.

[0009] As a further alternative, the blocking part is two protruding structures respectively provided on the two inner walls of the locking section.

[0010] As a further optional solution, the connector includes a net tail, which is secured within the locking section and abuts against the blocking step.

[0011] As a further optional solution, the placement section has a first arc-shaped guide surface at the end away from the locking section.

[0012] As a further optional solution, the end of the through segment away from the locking segment is provided with a second arc-shaped guide surface.

[0013] As a further optional solution, two clamping plates are provided on the inner wall of the power bank body, located on both sides of the cable hole, and the two clamping plates hold the charging cable.

[0014] As a further optional solution, one end of the clamp is fixed to the power bank body, and the other end is tilted at 2-5° towards the direction of the wire hole.

[0015] Compared with the prior art, the portable power bank of this application has at least the following advantages:

[0016] 1. The connector of the charging cable can be removed from the cable slot, so that all lengths of the charging cable outside the power bank body can be used during charging, avoiding wasted length of the charging cable at specific locations and increasing the effective usable length of the charging cable.

[0017] 2. Since the connector of the charging cable can be removed from the cable slot, the positional restrictions on the charging cable are reduced, giving the charging cable greater freedom when bending and swinging.

[0018] 3. The locking section in the cable slot prevents the connector from leaving the depth direction of the cable slot. At the same time, the blocking step abuts and blocks one end of the connector, so that when the charging cable is used as a lanyard, the connector cannot be detached from the cable slot, ensuring the stability of the overall structure. When it is necessary to remove the connector for charging, simply push the connector laterally (along the length direction of the cable slot) to remove the connector from the locking section, and the connector can be removed. The removal operation is simple and quick. Attached Figure Description

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.

[0031] 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.

[0032] 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.

[0033] refer to Figures 2 to 8 This utility model discloses a portable power bank, including a power bank body 1 and a charging cable 2. One end of the cable 21 is fixedly connected to a circuit board inside the power bank body 1, and the other end of the cable 21 is connected to a connector 22. The power bank body 1 is provided with a wire through hole 11 and a wire retaining groove 12. The wire through hole 11 is provided through the thickness direction of the outer wall of the power bank body 1 to allow the charging cable 2 to pass through to the outside of the power bank body 1. The wire retaining groove 12 is recessed on the outer surface of the power bank body 1. The cable groove 12 includes, along its length, a placement section 121, a locking section 122, and a cable passage section 123. The placement section 121 and the locking section 122 are for placing the connector 22, and the cable passage section 123 is for placing the cable body 21 of the charging cable 2. The locking section 122 is provided with a blocking part 1221 for preventing the connector 22 from leaving the depth direction of the cable groove 12. A blocking step 1232 is formed between the locking section 122 and the cable passage section 123, and the blocking step 1232 is used to abut against one end of the connector 22.

[0034] Specifically, such as Figure 2 and Figure 6 As shown, when the charging cable 2 is used as a lanyard, the connector 22 is placed in the placement section 121 of the cable clamping groove 12 (at this time, the connector 22 is not yet in the locking section 122), and then the connector 22 is pushed laterally so that the connector 22 enters the locking section 122, as shown. Figure 5 As shown, under the obstruction of the blocking part 1221, the connector 22 cannot leave from the depth direction of the wire-locking groove 12; at the same time, when the charging cable 2 is used as a lanyard, it will pull the cable body 21, and the cable body 21 will pull the connector 22 in the direction of the wire-passing segment 123, so that the connector 22 cannot be separated from the locking segment 122.

[0035] When charging is needed, simply push the connector 22 laterally to move it towards the placement section 121, disengaging it from the locking section 122, and then remove the connector 22 from the cable slot 12. This allows all lengths of the charging cable 2 outside the power bank body 1 to be utilized, avoiding wasted length at specific locations and increasing the effective usable length of the charging cable 2. Since the connector 22 of the charging cable 2 can be removed from the cable slot 12, positional restrictions on the charging cable 2 are reduced, giving it greater freedom of movement when bending and swinging.

[0036] Thus, the locking section 122 in the cable slot 12 can prevent the connector 22 from leaving the depth direction of the cable slot 12. At the same time, the blocking step 1232 abuts and blocks one end of the connector 22, so that when the charging cable 2 is used as a lanyard, the connector 22 cannot be detached from the cable slot 12, thus ensuring the stability of the overall structure. When it is necessary to remove the connector 22 for charging, it is only necessary to push the connector 22 laterally (along the length direction of the cable slot 12) to make the connector 22 detach from the locking section 122, and the disassembly operation can be realized. The disassembly operation is simple and quick.

[0037] Specifically, the above scheme is as follows: Figure 5 As shown, the blocking part 1221 consists of two protruding structures respectively disposed on the two inner walls of the locking section 122.

[0038] Among them, such as Figure 3 As shown, the connector 22 includes a mesh tail 221; the mesh tail 221 is a thickened transition structure between the connector 22 and the cable body 21, which can improve the connection stability between the connector 22 and the cable body 21; it should be noted that the structure of the charging cable 2 in this embodiment is a conventional charging cable 2 structure. The special description of the connector 22 including the mesh tail 221 is only for the convenience of the subsequent explanation of the specific cooperation structure between the charging cable 2 and the cable slot 12, and does not mean that this embodiment improves the structure of the charging cable 2.

[0039] like Figure 5 and Figure 5 As shown, the tail of the net 221 is secured within the locking section 122, and the tail of the net 221 abuts against the blocking step 1232. Generally, the cross-section of the tail of the net 221 is larger than that of the wire 21 but smaller than that of the connector 22, so the tail of the net 221 can abut against the blocking step 1232; furthermore, the depth of the placement section 121 can be set to be the same as the thickness of the connector 22, so that the connector 22 is basically flush with the outer surface of the power bank body 1, improving aesthetics; based on this, the blocking part 1221 is located above the tail of the net 221, which will not affect the alignment of the connector 22 with the outer surface of the power bank body 1.

[0040] In some embodiments, to further improve ease of operation, such as Figure 4 and Figure 6 As shown, the placement section 121 has a first arc-shaped guide surface 1211 at the end away from the locking section 122. Thus, when it is necessary to disassemble the connector 22, it is only necessary to push the connector 22 laterally. Under the guidance of the first arc-shaped guide surface 1211, the connector 22 will slide directly out of the wire clamping groove 12, without having to specifically remove the connector 22 from the placement groove, further simplifying the operation.

[0041] In addition, such as Figure 4 and Figure 6 As shown, the end of the through segment 123 away from the locking segment 122 is provided with a second arc-shaped guide surface 1231. In this way, the cable 21 can bend smoothly on the second arc-shaped guide surface 1231, and the sharp edges of the power bank body 1 are not allowed to squeeze the cable 21, thus preventing damage to the cable 21 structure.

[0042] In some embodiments, to increase the structural stability of the charging cable 2 and prevent the electrical connection between the charging cable 2 and the circuit board inside the power bank body 1 from becoming loose, such as... Figures 6 to 8 As shown, two clamping plates 13 are provided on the inner wall of the power bank body 1, located on both sides of the cable hole 11. The two clamping plates 13 clamp the cable body 21 of the charging cable 2. In this way, by clamping the cable body 21 with the clamping plates 13, when the charging cable 2 is used as a lanyard, even if the charging cable 2 is pulled to a certain extent, it is not easy to cause the electrical connection between the charging cable 2 and the circuit board to loosen.

[0043] Specifically, such as Figure 8 As shown, in this embodiment, one end of the clamping plate 13 is fixedly connected to the power bank body 1, and the other end is inclined towards the direction of the cable hole 11; in this embodiment, the inclination angle of the clamping plate 13 is K, and the angle K is 2-5°. In this way, the two clamping plates 13 can generate a certain clamping force on the cable 21 without damaging the cable 21.

[0044] 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.

[0045] 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.
