Embodiment 1

[0038] Such as Figure 1 ~ Figure 4 , Figure 14 As shown, the present invention includes a base body 100, a power adapter 2, a wire take-up device 3 for retracting the input power cord of the power adapter 2, a switch assembly 4, a control circuit 5, a DC power output interface 40, Interface expansion slot 6, notebook computer cooling fan 7, spare rechargeable battery 8, cooling fan for cooling the power adapter 2, the power adapter 2, the switch assembly 4, and the DC power output interface 40 respectively It is electrically connected to the control circuit 5, the power adapter 2 and the wire take-up device 3 are in a split structure, the heat dissipation fan is an axial flow fan 91, and the heat dissipation fan is directly connected to the power adapter 2 To dissipate heat, the rechargeable battery 8 is electrically connected to the output end of the power adapter 2 through the control circuit 5, and the cooling fan 7 of the notebook computer corresponds to the cooling hol...

Embodiment 2

[0043] Such as Figure 5 , Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the heat dissipation fan is a centrifugal fan 92, and the air outlet of the centrifugal fan 92 is directly aligned with the power adapter 2 to dissipate heat. The power adapter 2 is provided with heat dissipation holes, and the air outlet of the centrifugal fan 92 is directly aligned with the heat dissipation holes for penetrating forced ventilation and heat dissipation.

[0044] The remaining features of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0046] Such as Figure 7 ~ Figure 11 As shown, the difference between this embodiment and the first embodiment lies in that: the power adapter 2 and the wire take-up device 3 are of an integrated structure, and the wire take-up device 3 is also different from the first embodiment.

[0047]The take-up device 3 includes a housing assembly 31, a power cord 37, a power plug 30, and a power output interface 54. A hollow shaft 50 is fixed inside the housing assembly 31, and the power adapter 2 is located on the shaft. In the inner hollow of the column 50, the shaft column 50 is a stepped shaft, the periphery of the shaft column 50 is covered with a turntable 60, and the inner circumference of the turntable 60 is a stepped column that is rotatably adapted to the outer circumference of the shaft column 50 On the surface, two outer conductive layers 601, 602 are provided on different stepped cylinder surfaces of the turntable 60, two inner conductive layers 501, 502 are arranged on dif...

Abstract

The invention discloses a portable notebook computer base which is provided with a power supply and is convenient for carrying and use. The base of the invention comprises a base body (100), a power adapter (2), a wire folding device (3) used for folding the input power line of the power adapter (2), a switch component (4), a control circuit, and a DC power output interface (40); the power adapter (2), the switch component (4) and the DC power output interface (40) are electrically connected with a control circuit (5) respectively. The base of the invention can be widely applied in the field of notebook computers.

Description

technical field [0001] The invention relates to a portable notebook computer base with power supply. Background technique [0002] At present, rechargeable batteries are widely used as a fixed power source on notebook computer products, but the capacity of rechargeable batteries is limited, so that the working hours of notebook computers are relatively short, and the power of the rechargeable batteries will be exhausted after a few hours of general work. In addition, general notebook computers are also equipped with an external power adapter to obtain the rated voltage and current required for normal work. The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become disorganized and inconvenient to use when retracting and carrying. The main part of the adapter takes up a lot of space, although now The size of the notebook computer is getting smaller and smaller, and it is very co...
