Description

Technical Field

[0001] The utility model relates to a power bank, in particular to an AC plug power bank. Background Art

[0002] When the power bank is charging or powering a device, the internal circuit components will generate a certain amount of heat. If the heat cannot be dissipated in time, it may cause the internal temperature of the power bank to be too high, such as dangerous situations like battery bulging, or even explosion and fire;

[0003] For the power bank with AC plug for electricity storage, it is more likely to cause the situation of overheating. For the existing power bank, adding a fan has an obvious heat dissipation effect. For the power bank with good sealing, the air suction type heat dissipation is adopted to quickly reduce the temperature of the power bank. A relatively large fan is required for heat dissipation. Compared with the air blowing type with an air flow duct, the air suction type heat dissipation is insufficient. Therefore, for the power bank with AC plug for electricity storage, the air blowing type has better heat dissipation and can reduce the problem of overhigh internal temperature. Summary of the Invention

[0004] The utility model provides an AC plug power bank for reducing overheating inside the power bank and forming a stable heat dissipation air duct.

[0005] According to one aspect of the utility model, there is provided an AC plug power bank, including a battery, a PCB board and an AC plug. The battery and the AC plug are both electrically connected to the PCB board. It is characterized in that the AC plug power bank further includes,

[0006] A housing, which is detachably composed of an upper shell, a lower shell and a frame. A heat dissipation fan is arranged on the inner side of the lower shell. The heat dissipation fan is electrically connected to the PCB board and is powered by the battery. The heat dissipation fan is arranged opposite to the battery, and the heat dissipation fan adopts the air blowing type for heat dissipation;

[0007] A plurality of air outlets are opened on the surface of the upper shell, and a plurality of air guiding ribs are arranged on the inner side of the upper shell;

[0008] A data cable retraction module, which is electrically connected to the PCB board. A groove is arranged at one end of the housing for the power supply head of the data cable retraction module to be placed in parallel.

[0009] Further, a grid anti-slip part is arranged on the outer side of the frame of the housing, and side through holes are opened between the grids.

[0010] Further, dust-proof nets are arranged at the air outlets, the side through holes and the air inlet end of the heat dissipation fan.

[0011] Further, a heat insulation board is arranged in the middle of the lower shell, and the heat insulation board is arranged between the battery and the PCB board.

[0012] Further, the air guiding ribs are arranged in parallel along the length direction of the housing and are used to guide the blowing air flow to the periphery of the PCB board.

[0013] Further, the upper housing and the lower housing are mounted on the frame by elastic members.

[0014] Advantages of the present utility model:

[0015] The heat dissipation fan of the present utility model uses a blowing type for heat dissipation. By blowing air into the lower housing from the outside to the battery part, the blowing air diffuses to the periphery of the battery after encountering the battery. At the same time, a plurality of air outlets are provided on the surface of the upper housing. The blowing air exchanges heat inside the power bank, and after heat exchange, it is dissipated through the air outlets. When the power bank is placed vertically, the air volume flows upward after touching the battery and is guided along the air guiding ribs on the inner wall of the upper housing, while cooling the electronic components of the PCB board at the same time. The plurality of air outlets dissipate heat. And as long as the lower housing or the upper housing is not placed flat on the desktop to block the air inlets and outlets, the blowing air will find the air outlets for heat dissipation after cooling. Due to the small space of the power bank, the residence time of the blowing air is reduced. By the rotation of the fan, the air flow is forced to flow, taking away the heat, and the heat dissipation effect of the fan is obvious, which can quickly reduce the temperature of the power bank.

[0024] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0025] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are generally in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms are not used to limit the present utility model.

[0026] Please refer to Figures 1-5 as shown, which is a specific implementation manner of an AC plug power bank of the present utility model.

[0027] An AC plug power bank, comprising a battery 6, a PCB board 4 and an AC plug 41, the battery and the AC plug 41 are both electrically connected to the PCB board 4, and it is characterized in that the AC plug power bank further comprises,

[0028] a housing, the housing is detachably composed of an upper shell 1, a lower shell 3 and a frame 2, a cooling fan 7 is arranged inside the lower shell 3, the cooling fan 7 is electrically connected to the PCB board 4, and the power is provided by the battery 6, the cooling fan 7 is arranged opposite to the battery 6, and the cooling fan 7 uses blowing type heat dissipation;

[0029] a plurality of air outlets 11 are opened on the surface of the upper shell 1, and a plurality of air guiding ribs 12 are arranged inside the upper shell 1; among them, the air guiding ribs 12 are as Figure 5 shown, one end of the air guiding rib 12 gradually increases along the other end, presenting a trapezoid, the high-position air guiding rib 12 is arranged below the cooling fan 7, and the other end extends to the upper position of the PCB board 4;

[0030] a data cable retraction module 5, the data cable retraction module 5 is electrically connected to the PCB board 4, a groove is arranged at one end of the housing for the power supply head of the data cable retraction module 5 to be placed in parallel, and a rotating shaft and a storage housing are arranged inside the data cable retraction module 5, the data cable is drawn out from the storage housing through the rotating shaft, and the data cable is stored in the storage housing by inserting the data cable.

[0031] The heat dissipation fan of the utility model adopts a blowing heat dissipation method. By blowing air into the lower case 3 from the outside to the battery 6, the blowing air diffuses to the periphery of the battery after hitting the battery 6. At the same time, a plurality of air outlets 11 are provided on the surface of the upper case 1. The blowing air exchanges heat inside the power bank, and after heat exchange, it is dissipated through the air outlets 11. When the power bank is placed vertically, the air volume flows upward after hitting the battery, and is guided by the air guiding ribs 12 on the inner wall of the upper case 1, while cooling the electronic components of the PCB board 4. The plurality of air outlets 11 dissipate heat. As long as the lower case 3 or the upper case 1 is not placed flat on the desktop to block the air inlets and outlets 11, the blowing air will find the air outlets 11 for heat dissipation after cooling. Due to the small space of the power bank, the residence time of the blowing air is reduced. By the rotation of the fan, the air is forced to flow, taking away the heat. The heat dissipation effect of the fan is obvious, and the temperature of the power bank can be quickly reduced.

[0032] A grid anti-slip part 21 is arranged on the outer side of the frame 2 of the shell, and side through holes (not shown in the figure) are arranged between the grids.

[0033] Avoid blocking the air outlets 11 when the upper case of the power bank is placed on the desktop, so that a relatively closed space is formed inside the power bank. At the same time, the heat dissipation fan 7 is also started, resulting in poor blowing heat dissipation effect. The anti-slip property is increased through the grid anti-slip part 21, and the side through holes are not easily completely blocked.

[0034] Dust-proof nets are arranged at the air outlets 11, the side through holes and the air inlet end of the heat dissipation fan 7.

[0035] During use, since the heat dissipation is by blowing, arranging dust-proof nets at the inlet and outlet ends can prevent sundries from entering the power bank along with the blowing air and filter objects and part of the dust from entering.

[0036] A heat insulation plate 31 is arranged in the middle and upper part of the lower case 3, and the heat insulation plate 31 is arranged between the battery and the PCB board.

[0037] The internal components are reasonably arranged, and the heat-generating components are arranged as scattered as possible to avoid concentration in one area. The heat insulation plate 31 accelerates the formation of the air duct. When the blowing air hits the battery, the diffusion and retention of the air volume are reduced.

[0038] The air guiding ribs 12 are arranged in parallel along the length direction of the outer shell, and are used to guide the blowing air flow to the periphery of the PCB board 4.

[0039] When the heat dissipation fan 7 blows air, it first dissipates heat from the battery 6, and then is guided by the air guiding ribs 12, increasing the contact between the blowing air and the plurality of air outlets 11, and at the same time improving the heat dissipation of the PCB board 4.

[0040] The upper case 1 and the lower case 3 are installed on the frame 2 by elastic parts, which is convenient for the disassembly and cleaning of the upper case 1 and the lower case 2.
