[0027] 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.

[0028] This utility model embodiment provides a portable power supply, such as... Figures 1 to 4 As shown, the power bank includes a housing 1, a data cable 2, a charging interface 3, and a main control circuit board 4; the charging interface 3 and the data cable 2 are installed at one end of the housing 1, and the main control circuit board 4 is installed inside the housing 1 and located at the end close to the charging interface 3 and the data cable 2.

[0029] The main control circuit board 4 includes an AC component area 41 and a DC component area 42. AC component area 41 is equipped with AC component 43, and DC component area 42 is equipped with DC component 44. An isolation plate 5 is provided on the main control circuit board 4 to isolate the AC component area 41 and the DC component area 42.

[0030] In AC component 43 and its circuit, the direction of current constantly changes, generating a changing magnetic field. This changing magnetic field may induce electromagnetic induction in nearby DC component 44 and its circuit, causing interference signals in the current and voltage of DC component 44 and its circuit. For example, in an electronic device, if the wires of the AC circuit and the wires of the DC circuit are very close, the alternating magnetic field generated by the AC circuit will induce an electromotive force in the wires of the DC circuit, causing ripple or noise interference in the originally stable DC voltage of the DC circuit.

[0031] This invention divides the main control circuit board 4 into an AC component area 41 and a DC component area 42. DC component 44 is installed in DC component area 42, and AC component 43 is installed in AC component area 41. An isolation plate 5 is provided between the two areas to isolate AC component area 41 and DC component area 42. By separating DC component area 42 and AC component area 41 and providing the isolation plate, electromagnetic interference can be effectively reduced. The isolation plate acts as a shield, blocking the magnetic field generated by AC component 43 and its circuit from affecting DC component 44 and its circuit, thereby ensuring a more stable DC output from DC component 44 and its circuit, and reducing adverse effects on other DC-powered components in the power bank, such as preventing signal transmission errors and performance instability in electronic devices.

[0032] Specifically, AC component 43 can be a rectifier, etc., and DC component 44 can be a fuse, etc. The isolation plate 5 can be made of metal, such as aluminum plate, copper plate, etc., or it can be made of non-metallic material, such as a plastic plate wrapped with electromagnetic shielding cloth. There are no specific restrictions here.

[0033] Specifically, such as Figure 4 and Figure 5As shown, the isolation plate 5 includes a first extending vertical plate 51, a first extending horizontal plate 52, a second extending vertical plate 53, and a first extending inclined plate 54. The first extending vertical plate 51 and the second extending vertical plate 53 extend along the length direction of the power bank; the first extending horizontal plate 52 extends along the width direction of the power bank and is connected to the side of the first extending vertical plate 51 near the charging interface 3; the second extending vertical plate 53 is connected to the side of the first extending horizontal plate 52 away from the first extending vertical plate 51; the first extending inclined plate 54 is inclined and connected to the side of the second extending vertical plate 53 away from the first extending horizontal plate 52, and the first extending inclined plate 54 is inclined towards the AC component area 41. Through the directional setting and specific connection setting of the first extending vertical plate 51, the first extending horizontal plate 52, the second extending vertical plate 53, and the first extending inclined plate 54, the AC component area 41 and the DC component area 42 can be separated according to the actual layout requirements of the power bank's AC component area 41 and DC component area 44, which facilitates the setting of AC components 43 and DC components 44 and the utilization of space.

[0034] The charging interface 3 includes a USB-A interface 31 and a TYPE-C interface 32, which are located in the DC component area 42. The USB-A interface 31 and the TYPE-C interface 32 are mainly used to output DC power, transferring the electrical energy stored in the power bank to external devices such as mobile phones. They are also a type of DC component 44. Placing them in the DC component area 42, along with other DC components 44 related to DC power processing, facilitates the isolation of electromagnetic interference by the isolation plate 5.

[0035] In the DC component area 42, a first vertical circuit board 45 and a second vertical circuit board 46 are vertically mounted on the main control circuit board 4. A USB-A interface 31 is electrically connected to the first vertical circuit board 45, and a TYPE-C interface 32 is electrically connected to the second vertical circuit board 46. The first and second vertical circuit boards 45 and 46 provide the electrical connection mounting positions for the USB-A interface 31 and the TYPE-C interface 32, which are electrically connected to the main control circuit board 4 via the first and second vertical circuit boards 45 and 46. The first and second vertical circuit boards 45 and 46 facilitate the installation and setup of the USB-A interface 31 and the TYPE-C interface 32, and also facilitate the installation and setup of the main control circuit board 4. The USB-A interface 31 and the TYPE-C interface 32 are respectively soldered onto the first and second vertical circuit boards 45 and 46 to achieve electrical connection. The first vertical circuit board 45 and the second vertical circuit board 46 are vertically inserted onto the main control circuit board 4 relative to it, and corresponding pads are designed at the insertion points. They are then soldered together to achieve electrical connection between the first vertical circuit board 45, the second vertical circuit board 46 and the main control circuit board 4. Alternatively, slots (such as PCIe slots, USB slots, etc.) can be designed on the main control circuit board 4, and corresponding gold fingers or pins can be designed on the first vertical circuit board 45 and the second vertical circuit board 46 to achieve electrical connection between them and the main control circuit board 4. No specific restrictions are imposed here.

[0036] Furthermore, a control switch 6 is also installed on the end of the housing 1 where the charging interface 3 is located. The control switch 6 is electrically connected to one side of the second vertical circuit board 46, and the TYPE-C interface 32 is electrically connected to the other side of the second vertical circuit board 46. The control switch 6 controls the power bank's startup and shutdown. Separating the TYPE-C interface 32 and the control switch 6 on opposite sides of the second vertical circuit board 46 allows for efficient use of the board, resulting in a simple structure and a cleverly designed electrical connection between the TYPE-C interface 32 and the control switch 6. The pins of the control switch 6 are soldered onto the second vertical circuit board 46 for electrical connection.

[0037] A power plug 7 is installed on the side adjacent to the charging port 3 on the casing 1. The power plug 7 is electrically connected to the main control circuit board 4 of the AC component area 41; the data cable 2 is electrically connected to the main control circuit board 4 of the DC component area 42. The power plug 7 is used to plug into an external power socket to charge the power bank. The power plug 7 is also a type of AC component 43. By electrically connecting it to the main control circuit board 4 of the AC component area 41, it is arranged in a concentrated manner with the AC components 43, which are also related to AC power processing, to facilitate the isolation of electromagnetic interference to the DC components 44 through the isolation plate 5. The data cable 2 is used to output DC power, transmitting the electrical energy stored in the power bank to external devices such as mobile phones. It is also a type of DC component 44. By electrically connecting it to the main control circuit board 4 of the DC component area 42, it is arranged in a concentrated manner with the DC components 44, which are also related to DC power processing, to facilitate the isolation of electromagnetic interference through the isolation plate 5. The connection end of the data cable 2 is soldered to the main control circuit board 4 of the DC component area 42 to achieve its electrical connection. Users can charge their phones directly using data cable 2, without needing to use a separate data cable 2.

[0038] Further integration Figure 6 and Figure 7 As shown, a limiting groove 111 is provided on the other side of the housing 1 opposite to the power plug 7, and the charging head 21 of the data cable 2 is detachably locked in the limiting groove 111. In this design, the charging head 21 is detachably locked in the limiting groove 111. When in use, the data cable 2 can be taken out of the limiting groove 111 for charging. When not in use, the charging head 21 is locked back into the limiting groove 111 for fixation. At this time, the data cable 2 can also function as a lanyard, making it convenient to carry or store the power bank.

[0039] Specifically, the limiting groove 111 has a first inlet 1111 at one end near the charging interface 3, and the top edges of the two side walls of the first inlet 1111 are provided with locking protrusions 11111, and the two sides of the charging head 21 are engaged with the locking protrusions 11111. Through the locking of the locking protrusions 11111, the charging head 21 can be locked in the limiting groove 111 when the data cable 2 is used as a lanyard, and at the same time, it is also convenient to remove the charging head 21 from the limiting groove 111.

[0040] Furthermore, the housing 1 includes a side mounting shell 11, which is mounted on one end of the housing 1 where the charging interface 3 is located and extends to the opposite side of the power plug 7. A limiting groove 111 is provided on the side mounting shell 11. A first magnet 8 is mounted on the inner side of the side mounting shell 11 corresponding to the limiting groove 111, and the charging head 21 is magnetically attracted to the first magnet 8 in the limiting groove 111. The charging head 21 is further positioned in the limiting groove 111 by the magnetic attraction of the first magnet 8, improving the stability of the charging head 21 stored in the limiting groove 111. Specifically, a corresponding magnet can be provided in the charging head 21 to magnetically attract the first magnet 8, or the outer housing 1 of the charging head 21 can be made of a metal shell such as an iron shell that can be magnetically attracted; there are no specific limitations here.
