Detailed Implementation

[0025] 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.

[0026] like Figures 1 to 6 As shown, this utility model provides a specific embodiment of a portable power bank.

[0027] A portable power bank, reference Figure 1 and Figure 2The power bank includes a housing 100, a battery module 200, a circuit board module 300, a data cable 400, and a storage module 500. The housing 100 includes a shell 110 and a cover plate 120. The cover plate 120 is connected to the shell 110 to form a receiving cavity. The battery module 200 is housed in the receiving cavity at the end away from the cover plate 120. The storage module 500 and the circuit board module 300 are stacked and housed together in the receiving cavity at the end near the cover plate 120. The circuit board module 300 is electrically connected to the battery module 200. The cover plate 120 is provided with an avoidance opening 121 and... The receiving groove 122 and the clearance opening 121 connect the inside of the housing 110 and the outside. The receiving groove 122 is located on the outside of the cover plate 120. One end of the data cable 400 is electrically connected to the circuit board module 300. The wire of the data cable 400 is wound and arranged in the storage module 500. The other end of the data cable 400 is provided with an interface 410. The interface 410 passes through the clearance opening 121 and is exposed to the outside of the cover plate 120 and is accommodated in the receiving groove 122. The data cable 400 can drive the storage module 500 to rotate under the pull of external force, so as to release the wound wire to the outside of the housing 100.

[0028] When the data cable 400 is not needed to charge external devices, the cable 400 is wound and stored in the storage module 500, and the interface 410 is housed in the receiving groove 122 on the outside of the cover plate 120. When the data cable 400 needs to be used to charge external devices, the interface 410 can be removed from the receiving groove 122 on the outside of the cover plate 120 and pulled outward to pull the cable 400, thereby causing the storage module 500 to rotate and releasing the cable wound and stored in the storage module 500 to the outside of the outer shell 100 for user use.

[0029] Currently, most portable power banks on the market require a data cable to connect to and charge external electronic devices. This means that when carrying a portable power bank, you also need to carry the data cable separately, making it very inconvenient. To solve this problem, some portable power banks with built-in data cables have appeared on the market. Some designs leave the data cable exposed on the outside of the power bank, making it impossible to retract the cable into the casing, which is also inconvenient to carry. Others that allow the data cable to be retracted and retracted usually have an unreasonable internal layout, resulting in a large overall size and weight, making them inconvenient to carry.

[0030] In this embodiment, a portable power bank is designed, including a housing 100, a battery module 200, a circuit board module 300, a data cable 400, and a storage module 500. The housing 100 includes a shell 110 and a cover plate 120. The cover plate 120 is connected to the shell 110 to form a receiving cavity. The battery module 200 is housed in the receiving cavity at the end away from the cover plate 120. The storage module 500 and the circuit board module 300 are stacked and housed together in the receiving cavity at the end near the cover plate 120. The cover plate 120 is provided with a clearance opening 121 and a receiving groove 122. The circuit board module 300 is electrically connected to the battery module 200. One end of the data cable 400 is electrically connected to the circuit board module 300, and the wire of the data cable 400 is wound around the storage module 500. Inside the storage module 500, the other end of the data cable 400 is provided with an interface 410. The interface 410 passes through the clearance opening 121 and is exposed to the outside of the cover plate 120 and accommodated in the receiving groove 122. The data cable 400 can drive the storage module 500 to rotate under external force to release the wound cable to the outside of the outer shell 100. This solution plans the internal layout of the shell 110 according to the structural differences between the battery module 200, the storage module 500 and the circuit board module 300. The storage module 500 and the circuit board module 300 are stacked and then arranged side by side with the battery module 200, which makes the layout more reasonable, effectively reduces the space occupied by each module, and makes the overall size of the power bank smaller and more convenient to carry.

[0031] In one embodiment, reference Figure 2 and Figure 3 The storage module 500 includes a bracket 510 and a storage tray 520. The storage tray 520 is disposed on one side of the bracket 510 for winding and storing the cable of the data cable 400.

[0032] Specifically, refer to Figures 2 to 4The storage module 500 is used to wind and store the data cable 400 when it is not in use, thereby improving the portability of the power bank. The storage module 500 includes a bracket 510 and a storage tray 520. The storage tray 520 includes a base 521, a turntable 522, and a top cover 523. The turntable 522 is mounted on the base 521, and the top cover 523 covers the turntable 522. The turntable 522 has a protruding spool 5221 for winding the data cable 400 on the side facing the base 521. A column 5211 is provided at the center of the inner sidewall of the base 521, and the center of the turntable 522 is... The cover 523 has a through hole and a slot 5231 at the center of the inner side wall. When the turntable 522 is installed on the base 521 and the cover 523 covers the turntable 522, one end of the column 5211 will pass through the through hole and be inserted into the slot 5231 on the inner side wall of the cover 523, so as to limit the movement of the turntable 522 between the base 521 and the cover 523. When the part of the data cable 400 exposed outside the cover plate 120 is pulled by an external force, the wound data cable 400 moves under the action of the pulling force and drives the turntable 522 to rotate relative to the base 521, so as to release the wound cable outside the outer shell 100.

[0033] Further, refer to Figure 2 and Figure 4 A reset structure 524 is provided on the side of the turntable 522 facing the upper cover 523. When the data cable 400 is finished using, the turntable 522 rotates in the opposite direction under the action of the reset structure 524 to rewind and store the released cable part into the storage tray 520.

[0034] Further, refer to Figure 3 and Figure 5 The bracket 510 has a limiting groove 511 on the side near the storage tray 520. The storage tray 520 is housed in the limiting groove 511, and a buckle 512 is provided on the groove wall of the limiting groove 511. When the storage tray 520 is housed in the limiting groove 511, the surface of the storage tray 520 can abut against the buckle 512. A positioning block 513 is also provided on the groove wall of the limiting groove 511. The outer surface of the storage tray 520 is provided with a positioning groove 525 corresponding to the positioning block 513. When the storage tray 520 is housed in the limiting groove 511, the positioning block 513 in the limiting groove 511 can be housed in the positioning groove 525.

[0035] Further, refer to Figure 2 , Figure 3 and Figure 5The bracket 510 has multiple support feet 514 on the side away from the storage tray 520.
