[0002] An adjustable PD fast charging power bank is a type of power bank that supports the USB Power Delivery (PD) protocol and has the ability to adjust its output power. This means it can adjust the output voltage and current to ensure an efficient and safe charging process.

[0003] However, it still has the following drawbacks in practical use:

[0004] When a power bank is placed on a table and current or voltage needs to be adjusted, its small size means it needs to be picked up to make precise adjustments and accurately observe the values ​​on the display screen, which is inconvenient.

[0005] Therefore, a new type of adjustable PD fast charging power bank is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a structurally adjustable PD fast charging power bank to solve the problem mentioned in the background art: when the power bank is placed on the table and current and voltage need to be adjusted, it is inconvenient to pick it up in order to make accurate adjustments and observe the values ​​on the display screen due to its small size.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a structurally adjustable PD fast charging power bank, comprising:

[0009] The main body assembly includes a housing;

[0010] The convenient component includes a groove formed on the bottom surface of the housing, a support plate rotatably connected to the side wall of the groove, a telescopic rod rotatably connected to the side wall of the other end of the groove, a T-shaped baffle movably connected to a through hole formed on the lower section of the side wall of one end of the groove, a rectangular spring connected between the T-shaped baffle and the housing by screws, a telescopic block movably connected to the upper surface of the T-shaped baffle, and a slot connected to the lower section of the side of the housing by screws.

[0011] A protective assembly, the protective assembly including a fixing plate connected to the lower side section of the housing by screws.

[0012] Furthermore, there are two sets of telescopic rods, which are symmetrically and rotatably connected to the side wall of the groove and the side of the support plate.

[0013] Furthermore, the through hole is located on one side of the housing of the telescopic rod, and the slot is located directly above the T-shaped baffle.

[0014] Furthermore, the main component also includes a top cover connected to the upper end of the housing by screws and a display screen connected to the side of the housing by screws.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] Please see Figure 1-5 As shown, this embodiment is a structurally adjustable PD fast charging power bank, comprising:

[0035] The main component includes the housing 10;

[0036] The housing is injection molded as a single piece, and a circuit board is installed inside.

[0037] The convenient components include a groove 20 formed on the bottom surface of the housing 10, a support plate 21 rotatably connected to the side wall of the groove 20, a telescopic rod 22 rotatably connected to the side wall of the other end of the groove 20, a through hole 23 formed on the lower section of the side wall of one end of the groove 20, a T-shaped baffle 24 movably connected in the through hole 23, a rectangular spring 25 connected between the T-shaped baffle 24 and the housing 10 by screws, a telescopic block 26 movably connected to the upper surface of the T-shaped baffle 24, and a slot 27 connected to the lower section of the side of the housing 10 by screws.

[0038] The groove 20 serves a storage function, the support plate 21 and the telescopic rod 22 serve a support function, the telescopic rod 22 can realize the adjustment of position and force, the through hole 23 and the T-shaped baffle 24 serve a limiting function, the rectangular spring 25 can realize the adjustment of position and force, and the telescopic block 26 and the slot serve a limiting function 27.

[0039] There are two sets of telescopic rods 22, which are symmetrically and rotatably connected to the side wall of the groove 20 and the side of the support plate 21.

[0040] Through hole 23 is located on one side of housing 10 of telescopic rod 22, and slot 27 is located directly above T-shaped baffle 24;

[0041] The main components also include a top cover 11 connected to the upper end of the housing 10 by screws, and a display screen 12 connected to the side of the housing 10 by screws;

[0042] The top cover 11 serves a sealing function, and the display screen 12 can display current and voltage values;

[0043] The main components also include a knob 13 that is rotatably connected to the side of the housing 10, and heat dissipation holes 16 opened on the other three sides of the housing 10;

[0044] The knob 13 enables adjustment, and the heat dissipation hole 16 facilitates heat dissipation of the internal circuitry of the housing 10.

[0045] The main component also includes a detection port 14 connected to one side of the housing 10 by screws, and a charging port 15 connected to the middle of the side of the housing 10 by screws, with the charging port 15 located between the display screen 12 and the card slot 27.

[0046] The detection port 14 is used to detect whether the internal current and voltage of the housing 10 are normal. One part of the charging port 15 is used to charge the inside of the housing 10, and the other part is used by the power bank to charge external devices.

[0047] Working principle:

[0048] When it is necessary to adjust the current and voltage, press the telescopic block 26 in the slot 27. Under the action of the rectangular spring 25, the T-shaped baffle 24 moves along the through hole 23, causing the telescopic block 26 to move out of the slot 27 and the T-shaped baffle 24 to move out of the support plate 21.

[0049] At this point, it is freed from the restriction of the T-shaped baffle 24, and the telescopic rod 22 extends, causing the support plate 21 to rotate out of the groove 20.

[0050] The rotation of the support plate 21 causes the side of the housing 10 with the display screen 12 to rotate upward at an angle. At this time, the knob 13 can be rotated, and the current and voltage can be adjusted by observing the display screen 12.

[0051] After adjustment, press down on the top cover 11 to rotate the housing 10 downwards. At this time, the support plate 21 and the telescopic rod 22 are subjected to downward pressure and return to the state of being in contact with the table surface. Push the T-shaped baffle 24 inwards so that the telescopic block 26 is inserted into the slot 27. The other end of the T-shaped baffle 24 is below the support plate 21.

[0052] This step facilitates better adjustment of current and voltage, as well as clear observation of the display screen 12.

[0053] Please see Figure 6 As shown, this embodiment, based on embodiment 1 above, further includes:

[0054] The protective assembly includes a fixing plate 30 that is connected to the lower side of the housing 10 by screws;

[0055] The fixing plate 30 serves both connecting and supporting functions;

[0056] The protective assembly also includes a connecting shaft 31 connected to the fixed plates 30 by screws, and an L-shaped cover plate 32 rotatably connected to the connecting shaft 31;

[0057] The connecting shaft 31 serves a connecting function and also facilitates the rotation of the L-shaped cover plate 32, which in turn provides protection.

[0058] Working principle:

[0059] When it is necessary to adjust the current and voltage, flip the L-shaped cover plate 32 upward around the connecting shaft 31 between the fixed plates 30, and press down the telescopic block 26.

[0060] After adjustment, press down on the top cover 11. When the housing 10 fits against the tabletop, press the T-shaped baffle 24 inward. When the telescopic block 26 is inserted into the slot 27, the L-shaped cover 32 covers the telescopic block 26.

[0061] This step prevents accidental operation of the telescopic block 26 when plugging or unplugging the charging cable.
