A portable power bank contains a rechargeable battery that stores electrical energy and releases it when needed.

[0003] The power bank comes with a built-in charging cable. The connector end of the charging cable is electrically connected to the circuit board inside the power bank, and the charging cable extends through a lead-out port. The other end of the cable is used to plug into electronic devices to charge them. This eliminates the need to carry an additional charging cable when using the power bank.

[0004] Current power banks typically have a cam-like structure integrally formed around the charging cable connector, which prevents the connector from being pulled apart by external forces and maintains the normal operation of the charging cable. However, the presence of this cam-like structure not only increases the complexity of charging cable manufacturing, making the cable processing more difficult, but also makes it more troublesome to thread the charging cable into the connector, resulting in inconvenient overall assembly.

Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Current power banks typically have a cam-like structure integrally formed around the charging cable connector, which prevents the connector from being pulled apart by external forces and maintains the normal operation of the charging cable. However, the presence of this cam-like structure not only increases the complexity of charging cable manufacturing, making the cable processing more difficult, but also makes it more troublesome to thread the charging cable into the connector, resulting in inconvenient overall assembly.

[0037] Specifically, because the locking mechanism requires the protruding part to be larger than the outlet to achieve proper locking, during assembly, the charging cable's connecting end cannot be directly inserted into the outlet from the outside. Instead, the charging end of the cable (before the charging head is attached) must be inserted from the inside of the outlet before the charging head is assembled. However, this design means that when assembling the charging head on the charging end, the power bank housing is already assembled with the charging cable. This makes not only threading the charging cable into the outlet cumbersome (it must be done using the charging end), but also makes the assembly process complicated, as the charging cable is still attached to the power bank housing.

[0038] In response, this utility model provides a portable power bank, such as... Figures 1 to 3As shown, the power bank includes a housing 1, a circuit board 2, a charging cable 3, and a limiting clamping member 4; the circuit board 2 is installed inside the housing 1, and the charging cable 3 includes a connecting end 31 and a charging end 32; an outlet 11 is provided on the side of the housing 1, the connecting end 31 of the charging cable 3 is electrically connected to the circuit board 2, and leads out from the outlet 11; the limiting clamping member 4 is installed inside the housing 1 and is pressed against the connecting end 31 to fix the connecting end 31.

[0039] The power bank of this utility model is equipped with a limiting clamping component 4, which is installed inside the housing 1 and clamps onto the connecting end 31. This fixes the connecting end 31 of the charging cable 3, preventing poor electrical connection between the connecting end 31 and the circuit board 2 due to external pulling, thus ensuring the normal use of the charging cable 3. In this way, while ensuring the fixed and limited connection of the connecting end 31 of the charging cable 3, there is no need to set a locking protrusion structure on the connecting end 31. The processing of the data cable is simple, and during assembly, the charging head 33 of the charging end 32 of the charging cable 3 can be assembled first, and then the connecting end 31 can be directly inserted into the outlet 11 to make electrical connection with the circuit board 2. Compared with the above assembly process, the overall assembly operation of this utility model is more convenient.

[0040] Furthermore, this utility model achieves data cable fixation by using the limiting clamping member 4 to press the connecting end 31. The clamping force is large, which can achieve firm clamping of the connecting end 31 and secure fixation of the data cable.

[0041] Specifically, the limiting clamping member 4 includes a pressing part 41 that is disposed on one side and protrudes outward, and the pressing part 41 presses against one side of the connecting end 31. The setting of the pressing part 41 enables the limiting clamping member 4 to press and fix the connecting end 31 through the pressing part 41, so that the connecting end 31 is kept in the predetermined installation position, and the pressing and fixing effect is good.

[0042] Furthermore, such as Figures 4 to 8 As shown, limiting clamping ribs 5 are provided inside the housing 1 at the position corresponding to the connecting end 31 and on the limiting clamping member 4 at the position corresponding to the connecting end 31; the limiting clamping ribs 5 clamp the side of the connecting end 31. In this solution, limiting clamping ribs 5 are provided on the housing 1 and the limiting clamping member 4 on both sides of the connecting end 31. By clamping the side of the connecting end 31 with the limiting clamping ribs 5, the fixing effect of the connecting end 31 can be further improved.

[0043] A support rib 123 is provided inside the housing 1 corresponding to the connecting end 31. The support rib 123 is arranged opposite to the pressing part 41, and the other side of the connecting end 31 is supported on the support rib 123. The support rib 123 can support the connecting end 31. When the pressing part 41 presses down to tighten the connecting end 31, the support rib 123 and the pressing part 41 work together to tighten the connecting end 31, further improving the fixing effect of the connecting end 31.

[0044] Specifically, further integration Figure 9 As shown, the power bank includes mounting screws 20, a first stud 122 inside the housing 1, and a mounting cavity 42 with a bottom opening inside the limiting clamping member 4. The top of the limiting clamping member 4 has a mounting hole 43 communicating with the mounting cavity 42. The mounting cavity 42 is fitted onto the first stud 122, and the mounting screws 20 pass through the mounting hole 43 and are screwed onto the first stud 122, thus clamping the limiting clamping member 4. In this design, the mounting screws 20 are used to install the limiting clamping member 4 onto the first stud 122. By clamping the limiting clamping member 4, the limiting clamping member 4 clamps the connecting end 31; specifically, the lower pressing part 41 clamps the connecting end 31. The limiting clamping member 4, fitted onto the first stud 122 by the mounting cavity 42, achieves quick, secure, and stable installation. Specifically, the first stud 122 has a screw hole, and the mounting screw 20 is screwed into the screw hole. The mounting hole 43 can be a screw hole or a through hole without internal threads, which is not specifically limited here.

[0045] Further integration Figure 10 and Figure 11 As shown, the housing 1 includes a first sub-shell 12 and a side shell 13. The first sub-shell 12 has a shell mounting groove 121 on its side, and the side shell 13 is installed in the shell mounting groove 121. An outlet 11 is formed at both the shell mounting groove 121 and the side shell 13. The design of the shell mounting groove 121 improves the installation stability of the side shell 13. The housing 1 also includes a second sub-shell 15, which covers the first sub-shell 12. The two can be assembled by snap-fit ​​connection or by screws. The side shell 13 can be glued to the shell mounting groove 121.

[0046] Specifically, the first stud 122 and the support rib 123 are both located in the first sub-shell 12, and the circuit board 2 is also installed in the first sub-shell 12 by screws.

[0047] The housing mounting groove 121 and the side shell 13 extend together to the adjacent side where the outlet 11 on the first sub-shell 12 is located; on the adjacent side, the side shell 13 is provided with a receiving groove 131, and the charging end 32 is provided with a charging head 33, which can be received in the receiving groove 131. The receiving groove 131 is provided on the independent side shell 13, which facilitates the processing design of the receiving groove 131 and also facilitates the processing design of the overall shell 1.

[0048] Specifically, the receiving slot 131 has a connecting port 132 at one end near the outlet 11. The charging cable 3 passes through the connecting port 132, and the charging head 33 forms a blocking position with the connecting port 132. The charging head 33 can form a blocking position with the connecting port 132, and the charging cable 3 can not only be used for charging but also as a lanyard, making it convenient for users to take, store, or carry the power bank. During assembly, after the charging head 33 is assembled on the charging end 32, the connecting end 31 passes through the connecting port 132 and the outlet 11 in sequence, and enters the housing 1 to be soldered to the circuit board 2 to achieve electrical connection. The circuit board 2 serves as the power bank's circuit control and distribution component, and can adopt embodiments known to those skilled in the art, which will not be described in detail here. Furthermore, the power bank also includes a rechargeable battery 9, a charging interface 10, etc., electrically connected to the circuit board 2, which can adopt embodiments known to those skilled in the art, which will not be described in detail here.

[0049] Furthermore, a first positioning structure 6 is provided at the receiving slot 131, and a second positioning structure is provided on the charging head 33. The charging head 33 is positioned in the receiving slot 131 by the first positioning structure 6 and the second positioning structure. The cooperation of the first positioning structure 6 and the second positioning structure can improve the stability of the charging head 33 in the receiving slot 131, and the charging head 33 will not easily detach from the receiving slot 131. When charging is needed, the user pulls the charging head 33 out of the receiving slot 131 for use.

[0050] Specifically, in one embodiment, the first positioning structure 6 is a first magnet, which is installed between the housing mounting groove 121 and the receiving groove 131; the charging head 33 has a metal material or a second magnet that can be magnetically attracted to the first magnet. Through the magnetic attraction of the first magnet, the charging head 33 can be magnetically attracted into the receiving groove 131, thus achieving the positioning of the charging head 33. The magnetic attraction of the first magnet also facilitates the user to place the charging head 33 into the receiving groove 131. When the user brings the charging head 33 close to the receiving groove 131, the charging head 33 can automatically be sucked into the receiving groove 131. The charging head 33 can be independently equipped with a second magnet or a magnetically attracted metal block, such as an iron block, which magnetically attracts the first magnet. In this case, the second positioning structure is the second magnet or the metal block; alternatively, the outer shell of the charging head 33 can be a metal shell, such as an iron shell, in which case the metal shell can directly serve as the second positioning structure and magnetically attract the first magnet. In another embodiment, locking ribs can be provided along the upper and lower edges of the receiving groove 131, and the two sides of the charging head 33 can be locked inside the locking ribs to achieve the storage and positioning of the charging head 33. In this case, the locking ribs are the first positioning structure 6, and the two sides of the charging head 33 are the second positioning structure.

[0051] Furthermore, at the location corresponding to the first magnet, the housing mounting groove 121 is recessed inward and the receiving groove 131 is recessed outward to form a mounting cavity 14, in which the first magnet is inserted. The mounting cavity 14 is formed by the recesses of the housing mounting groove 121 and the receiving groove 131, thus enabling the installation of the first magnet. The structure is simple, the installation is firm, and the first magnet can be installed simultaneously when assembling the side shell 13, making assembly convenient.

[0052] Furthermore, the side shell 13 is made of a light-transmitting material, and a light-transmitting port 124 is provided on the shell mounting groove 121 next to the outlet 11. The power bank also includes a display element 7 for displaying the power bank's status. The display element 7 is electrically connected to the circuit board 2 and mates with the light-transmitting port 124. The display element 7 can be a display device known to those skilled in the art, such as an LCD display. Making the side shell 13 a light-transmitting material can protect the display element 7 while ensuring its normal display function. Specifically, the display element 7 can display status information such as the power bank's charge level and charging status.

[0053] Further integration Figure 12 and Figure 13 As shown, the power bank also includes a mounting component 8 inserted into the circuit board 2. The mounting component 8 has a mounting groove 81, in which the display element 7 is installed. An upper pressing part 82 protrudes from the top edge of the mounting groove 81, and a lower supporting part 83 protrudes from the bottom edge of the mounting groove 81. The upper pressing part 82 presses against the top of the display element 7, and the lower supporting part 83 supports the bottom of the display element 7. The mounting component 8 ensures a stable installation of the display element 7. The display element 7 is positioned within the mounting groove 81, and the upper pressing part 82 and the lower supporting part 83 further enhance installation stability. The display element 7 can be further bonded to the mounting groove 81 using adhesive or similar substances.

[0054] Specifically, the bottom ends of the mounting component 8 are provided with insertion protrusions 84, which are inserted into the corresponding insertion holes 21 on the circuit board 2, thereby realizing the installation of the mounting component 8.
