Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a mobile power supply. Background Technology

[0002] With the widespread adoption of smart devices, power banks have become an indispensable accessory in people's daily lives and work. However, existing power banks still have many shortcomings in the design and storage of their connecting cables, making it difficult to meet users' needs for convenience and reliability.

[0003] Most existing power bank cables are either "external" or "loosely built-in." One type is the external cable, requiring users to carry a separate charging cable and manually connect the power bank to the device being charged. This not only increases the risk of cable loss but also adds to the carrying burden. The other type is the built-in cable, which solves the cable loss problem, but the cable is often loosely stored without an effective fixing structure. During transport or use, the cable can easily move around inside the casing, rubbing and colliding with other components. Over time, this can lead to cable wear and breakage, affecting the power bank's lifespan. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a portable power bank. Through the connection of the plug and the fixed socket on the circuit board, the connecting cable can be accurately positioned and fixed in the storage cavity when not in use, avoiding the problems of loose, wobbly, worn, broken, or detached connecting cables in traditional portable power banks, and improving the neatness and structural stability of cable storage.

[0005] The objective of this utility model is achieved through the following solution: This utility model discloses a portable power bank, including a connecting cable, a circuit board, and a housing; the housing has a storage cavity, the circuit board is housed in the storage cavity, one end of the connecting cable extends into the housing and is electrically connected to the circuit board, and the other end of the connecting cable is provided with a connecting plug, which can extend into the storage cavity and be inserted into a fixed socket on the circuit board for fixation.

[0006] Furthermore, the storage cavity is provided with a fixing seat, which is located inside the storage cavity 31. When the connecting plug is inserted into the fixing socket, part of the connecting plug is located in the receiving groove of the fixing seat, and the end of the connecting plug passes through the receiving groove and is inserted into the fixing socket.

[0007] Furthermore, the fixing base has a first opening at the end of the receiving groove near the housing, the housing has a second opening corresponding to the first opening, and the receiving groove has a third opening at the end away from the first opening. The connecting plug of the connecting wire passes through the second opening and the first opening and is inserted into the fixing base, and the end of the connecting plug passes through the third opening and extends into the fixing socket.

[0008] Furthermore, at least one of the first opening and the second opening is fitted with a silicone ring to further prevent the connector from detaching from the housing.

[0009] Furthermore, the fixed socket is provided with a magnetic housing for fixing the connector plug inside the fixed socket.

[0010] Furthermore, the end of the connector has a metal housing, and the connector is fixed in the fixed socket by magnetically attracting the metal housing.

[0011] The power bank also includes at least one charging port, which is located on the end face of the power bank.

[0012] Furthermore, the power bank also includes a button switch located on the side of the power bank, which is used to turn the power bank on or off.

[0013] Furthermore, the housing includes an upper housing and a lower housing, which are fastened together by a snap-fit ​​structure to form the storage cavity.

[0014] Furthermore, a silicone ring is provided on the outer periphery of one end of the housing located on the connecting line.

[0015] The advantage of this invention lies in its mechanical locking of the connecting cable in its retracted state through the insertion and engagement of the plug with the fixed socket on the circuit board. This solves the problem of loose, wobbly connecting cables and wear caused by friction with the casing in traditional power banks. This "plug-socket" fixing method precisely limits the displacement of the connecting cable, reduces fatigue damage at the cable root caused by pulling and bending, and significantly extends the cable's lifespan. When not in use, the plug can be directly inserted into the fixed socket for storage, eliminating the need for additional winding or clipping. When in use, simply unplugging the plug allows for quick charging of the device, saving the steps of finding external cables or tidying up loose cables. This "plug-and-play" design is particularly suitable for outdoor and commuting scenarios, making charging more efficient. Attached Figure Description

[0024] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0025] Please see Figures 1 to 5 This utility model discloses a portable power bank, comprising: The device includes a connecting wire 10, a circuit board 20, and a housing 30. The housing 30 has a storage cavity 31, and the circuit board 20 is housed in the storage cavity 31. One end of the connecting wire 10 extends into the housing 30 and is electrically connected to the circuit board 20. The other end of the connecting wire 10 has a connecting plug 11, which can extend into the storage cavity 31 and be inserted into the fixing socket 21 on the circuit board 20 for fixation.

[0026] Please see Figure 4 and Figure 5 The storage cavity 31 is provided with a fixing seat 32, which is located inside the storage cavity 31. When the connector 11 is inserted into the fixing socket 21, part of the connector 11 is located in the receiving groove 321 of the fixing seat 32, and the end of the connector 11 passes through the receiving groove 321 and is inserted into the fixing socket 21. The receiving groove 321 of the fixing seat 32 can play a role in assisting in positioning and stabilizing the connector 11, effectively preventing the connector 11 from falling out of the fixing socket 21 due to shaking when stored, further improving the reliability of storage, and also enhancing the stability of the connection between the connector 11 and the fixing socket 21.

[0027] Please see Figure 5The fixing base 32 has a first opening 322 at the end of the receiving groove 321 near the housing 30. The housing 30 has a second opening 33 corresponding to the first opening 322. The receiving groove 321 has a third opening 323 at the end away from the first opening 322. The connector 11 of the connecting cable 10 passes through the second opening 33 and the first opening 322 and is inserted into the fixing base 32. The end of the connector 11 passes through the third opening 323 and extends into the fixing socket 21. When it is necessary to use the power bank to charge the electronic device, the user pulls the connector 11 out of the fixing socket 21 on the circuit board 20. The connector 11 disengages sequentially from the third opening 323, the receiving groove 321, the first opening 322, and the second opening 33. At this time, the connector 11 is completely detached from the housing 30 and the fixing base 32. Then, the connector 11 is inserted into the charging interface of the electronic device. The battery inside the power bank transmits the stored electrical energy to the electronic device through the circuit board 20 via the connecting cable 10, realizing the charging function. When charging is complete or the power bank is no longer needed, the user unplugs the connector 11 from the charging port of the electronic device, then inserts the connector 11 into the second opening 33 of the housing 30, passing through the second opening 33 and the first opening 322 of the fixing base 32 into the receiving groove 321. Guided by the receiving groove 321, the end of the connector 11 smoothly passes through the third opening 323 and inserts into the fixing socket 21 on the circuit board 20, thus fixing the connector 11. At this time, the connector 11 is partially located in the receiving groove 321, and with the combined action of the fixing base 32 and the fixing socket 21, the connector 11 is firmly fixed in the storage cavity 31, preventing shaking and loosening.

[0028] Please see Figure 1 At least one of the first opening 322 and the second opening 33 is fitted with a silicone ring 34 to further prevent the connector 11 from detaching from the housing 30. The silicone ring 34 is elastic and fits tightly when the connector 11 passes through, increasing friction and preventing the connector 11 from accidentally detaching.

[0029] The fixed socket 21 is equipped with a magnetic housing for securing the connector 11 within it. This magnetic securing method is convenient to operate, quickly generating an attractive force when the connector 11 is inserted into the fixed socket 21, preventing accidental detachment, and also facilitating the removal of the connector 11, thus improving ease of use. The magnetic housing is made of a strongly magnetic material, preferably such as a ferrite magnet or neodymium iron boron magnet, and its shape is adapted to the shape of the fixed socket 21, either covering the outside of the fixed socket 21 or embedding it inside. The magnetic strength of the magnetic housing is designed to ensure a stable attraction of the connector 11 without making it difficult to remove due to excessive magnetism. The end of the connector 11 has a metal housing, which is magnetically attracted to the metal housing to fix the connector 11 inside the fixed socket 21. This magnetic fixing method is convenient to operate, and can quickly generate an attractive force when the connector 11 is inserted into the fixed socket 21 to prevent it from accidentally falling off. It also makes it easy to pull out the connector 11, improving the convenience of use.

[0030] Please see Figure 2 and Figure 3 The housing 30 includes an upper housing 35 and a lower housing 36, which are fastened together by a snap-fit ​​structure to form the storage cavity 31. The snap-fit ​​structure includes a slot on the edge of the upper housing 35 and a corresponding hook on the edge of the lower housing 36. The hook matches the shape of the slot, and when fastened, the hook fits snugly into the slot, achieving a secure connection between the upper housing 35 and the lower housing 36. This snap-fit ​​connection method requires no additional connectors, is easy to assemble and disassemble, and facilitates the installation, maintenance, and replacement of internal components.

[0031] A silicone ring 34 is also provided on the outer periphery of one end of the housing 30 where the connecting wire 10 is located. This silicone ring 34 is made of highly elastic silicone material, and its inner diameter matches the outer diameter of the connecting wire 10. It is fitted onto the outer periphery of the connecting wire 10 with an interference fit and fits tightly against the outer wall of the housing 30. The silicone ring 34 enhances the seal between the connecting wire 10 and the housing 30, preventing dust and moisture from entering the storage cavity 31 through the gap between them. It also reduces friction between the connecting wire 10 and the edge of the housing 30 during insertion, removal, and use, thus protecting the connecting wire 10 and extending its service life.

[0032] Please see Figure 2 The power bank also includes a push-button switch 40, located on the side of the power bank. The push-button switch 40 is used to turn the power bank on or off, allowing users to control the device's operating status and save power. The push-button switch 40 is connected to a control circuit on the circuit board 20. When not pressed, the circuit is open, and the power bank is not working. When the push-button switch 40 is pressed, the control circuit is activated, the power bank starts up and enters the working state, and can output power. Pressing the push-button switch 40 again disconnects the control circuit, and the power bank stops working, avoiding unnecessary power consumption.

[0033] Please see Figure 1The power bank also includes at least one charging port 50, located on the end face of the power bank. The charging port 50 is located on the end face of the power bank, and there is at least one. Its type can be selected according to actual needs, such as a USB-A port, a USB-C port, or a combination of multiple types of ports to adapt to the charging needs of different electronic devices. When using the power bank to power an electronic device, pressing the side button switch 40 turns on the power bank circuit and starts it up. At this time, the electrical energy stored in the internal battery is transferred to the circuit board 20. The discharge circuit on the circuit board 20 converts the electrical energy output by the battery and adjusts it to adapt to the voltage and current of the electronic device. If using the connecting cable 10, the connecting plug 11 is unplugged from the fixed socket 21 and inserted into the charging port 50 of the electronic device. The converted electrical energy is transferred to the electronic device via the connecting cable 10 and the connecting plug 11 to power the device. If using the charging port 50, one end of the external charging cable is inserted into the charging port 50, and the other end is inserted into the electronic device. Electrical energy is transferred to the electronic device via the charging port 50 and the external charging cable to power the device.

[0034] The power bank also includes a display screen electrically connected to the circuit board 20. The display screen is located on the surface of the power bank's housing 30 and can display information such as the remaining power and charging status of the power bank in real time, making it convenient for users to understand the device's status.

[0035] The portable power bank provided by this utility model achieves mechanical locking of the connecting cable 10 in its retracted state through the insertion and engagement of the connecting plug 11 with the fixed socket 21 on the circuit board 20. This solves the problem of loose and wobbly connecting cables 10 and wear caused by friction with the housing 30 in traditional portable power banks. This "plug-socket" fixing method can precisely limit the displacement of the connecting cable 10, reduce fatigue damage caused by pulling and bending at the cable root, and significantly extend the service life of the connecting cable 10. When not in use, the connecting plug 11 can be directly inserted into the fixed socket 21 for storage, without the need for additional winding or clipping. When in use, simply unplugging the plug allows for quick charging of the device, eliminating the need to find external cables or tidy up loose cables. This "plug-and-play" design is particularly suitable for outdoor and commuting mobile scenarios, making charging more efficient.
