Embodiment Construction

[0014] Please also see figure 1 and figure 2 , a preferred embodiment of the power supply device 100 includes a laptop battery 10 and a voltage converter 20 . The voltage converter 20 is detachably electrically connected to the laptop battery 10 . The voltage converter 20 is used to convert the first voltage output by the battery 10 of the notebook computer into a second voltage for output, so as to provide power for other portable electronic products, such as mobile phones and digital cameras. In addition, the voltage converter 20 can also be electrically connected with an external power supply providing a third voltage, so as to convert the third voltage into a fourth voltage matching the charging voltage of the laptop battery 10 , so as to charge the laptop battery 10 . How the voltage converter 20 converts the voltage of the laptop battery 10 will be described in detail below.

[0015] The laptop battery 10 includes a first shell 11 , a connecting portion 12 , two firs...

Abstract

The invention provides a voltage converter used for converting the output voltage of a laptop battery. The laptop battery comprises a first housing, a first clamping piece and a first port, wherein the first clamping piece and the first port are arranged on the first housing. The voltage converter comprises a second housing and a circuit board accommodated in the second housing, wherein a second clamping piece capable of being clamped with the first clamping piece is arranged on the second housing; a second port, a first conversion module and a third port are arranged on the circuit board. When the second clamping piece is clamped with the first clamping piece, the second housing is fixed on one side of the first housing, the second port is electrically connected with the first port, and the first conversion module can receive a first voltage output by the first port, convert the first voltage into a second voltage, and output the second voltage through the third port.

Description

technical field [0001] The invention relates to a voltage converter, in particular to a voltage converter used for converting the output voltage of a notebook computer battery. Background technique [0002] Laptop battery is a portable high-capacity power supply that can be charged and discharged, and its power is usually greater than 4000mAh. Laptop batteries only have interfaces compatible with the corresponding laptop, not with other electronic products. Moreover, the output voltage of a notebook computer battery is usually about 12V, while the charging voltage of most portable electronic products, such as mobile phones and digital cameras, is lower than 12V. Therefore, the laptop battery cannot directly supply power to other electronic products, which reduces the utilization rate of the laptop battery. Contents of the invention [0003] In view of this, it is necessary to provide a voltage converter that can improve the utilization rate of the notebook computer batte...
