[0030] 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.
[0031] This utility model embodiment provides a portable power supply, such as... Figures 1 to 3 , Figure 9 As shown, the power bank includes a housing 1, a control circuit board 2, and a charging cable 3; the control circuit board 2 is installed inside the housing 1, and the side of the housing 1 has a cable outlet 131 and a cable routing channel 11; the charging cable 3 includes a connector and a charging head 31, and the connector is electrically connected to the control circuit board 2 inside the housing 1.
[0032] After the charging cable 3 is led out through the cable outlet 131 inside the housing 1, it passes through the cable channel 11 from the first end 111 and exits from the second end 112 of the cable channel 11. The charging head 31 is locked to the second end 112. The charging cable 3 between the cable outlet 131 and the first end 111 forms a hanging part 32.
[0033] The portable power bank of this invention has a cable routing channel 11 on the side of the housing 1. The connector end of the built-in charging cable 3 is electrically connected to the control circuit board 2 inside the housing 1. After being led out through the cable outlet 131, it passes through the cable routing channel 11 from the first end 111 and exits from the second end 112 of the cable routing channel 11. The charging head 31 is locked to the second end 112. The charging cable 3 between the cable outlet 131 and the first end 111 forms a lanyard portion 32. In this invention, the charging cable 3 is threaded through the cable routing channel 11, and the locking mechanism of the charging head 31 prevents the charging cable 3 from coming out of the cable routing channel 11. The charging cable 3 forms a lanyard portion 32 between the cable outlet 131 and the first end 111, realizing the lanyard function of the charging cable 3. This avoids the problem in the prior art where the charging head 31 is not reliably fixed in the storage slot and is prone to unexpected detachment, affecting its use.
[0034] Specifically, the length of the charging cable 3 portion outside the housing 1 is redundantly set relative to the length of the routing channel, thereby forming a lanyard portion 32 between the charging cable 3 at the cable outlet 131 and the first end 111. The size of the lanyard portion 32 depends on the length of the charging cable 3 portion outside the housing 1, and can be designed as needed by those skilled in the art. When charging is required, the user pulls the charging cable 3 from one end of the charging head 31 to charge.
[0035] Specifically, such as Figures 4 to 6 As shown, the housing 1 includes a side shell 12 and an inner fastener 13. The inner fastener 13 is provided with a first channel cable routing groove 132. The inner fastener 13 is installed on the inner side surface of the side shell 12, and the first channel cable routing groove 132 and the inner side surface of the side shell 12 together form a cable routing channel 11. By setting the inner fastener 13, the first channel cable routing groove 132 on the inner fastener 13 together with the inner side surface of the side shell 12 forms a cable routing channel 11, which facilitates the setting of the cable routing channel 11 and facilitates the production and assembly of the charging cable 3, the housing 1, and the inner fastener 13. The inner fastener 13 can be fastened to the multiple snap holes 16 of the protruding ribs on the inner side surface of the side shell 12 by multiple snaps 15.
[0036] like Figure 7 and Figure 8As shown, the inner fastener 13 is also provided with an inner cable routing groove 133, and the charging cable 3 part inside the housing 1 is installed in the inner cable routing groove 133. The inner fastener 13 is further provided with an inner cable routing groove 133 to facilitate the installation and layout of the charging cable 3 part inside the housing 1. The first channel cable routing groove 132 and the inner cable routing groove 133 are arranged vertically. The cable outlet 131 is located at one end of the inner cable routing groove 133.
[0037] Furthermore, the bottom wall of the inner cable tray 133 is provided with a locking opening 134, and the charging cable 3 is provided with a first locking part 33, which is locked in the locking opening 134. The locking opening 134 and the first locking part 33 form a locking position, thereby fixing the charging cable 3 part inside the housing 1. When the lanyard 32 or the charging head 31 is pulled, the first locking part 33 is locked in the locking opening 134, preventing external pulling from affecting the electrical connection between the charging cable 3 connection end and the control circuit board 2, and ensuring the stability of the electrical connection between the charging cable 3 and the control circuit board 2. The first locking part 33 is integrally formed on the charging cable 3.
[0038] Specifically, at the location corresponding to the locking opening 134, a first limiting groove 4 is provided on the side wall of the inner wiring groove 133 and the inner side of the side shell 12, and the two sides of the first locking part 33 are respectively locked in the two first limiting grooves 4. The first limiting grooves 4 provided on the side wall of the inner wiring groove 133 and the inner side of the side shell 12 can further fix the first locking part 33, improve the fixation of the first locking part 33, and further ensure the stability of the electrical connection between the charging cable 3 and the control circuit board 2.
[0039] A first opening 121 is provided on the side shell 12, and a first end 111 and an inner wiring groove 133 are connected to the first opening 121; the lanyard portion 32 can be extended out of the first opening 121. The first opening 121 exposes the lanyard portion 32, making it convenient for the lanyard portion 32 to be extended from the shell 1. A second locking portion 34 is provided on the lanyard portion 32, and a first locking portion 33 can be locked with the first opening 121 or the first end 111. In this design, when the charging head 31 is pulled out for use, the first locking portion 33 can be locked with the first opening 121 or the first end 111, which can further ensure the stability of the electrical connection between the charging cable 3 and the control circuit board 2.
[0040] A second cable routing groove 122 is provided on the side shell 12 to form a cable routing channel 11. The second cable routing groove 122 communicates with the first cable routing groove 132.
