[0019] In order to facilitate and briefly understand the other features and advantages of the present invention and the effects achieved by the present invention, the present invention is described in detail with the accompanying drawings as follows:

[0020] See also Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a power supply extension device for a notebook computer, which comprises: a notebook computer 1, a wireless charging device 2 and a solid state battery (SSB) 3.

[0021] The laptop computer 1 is provided with an induction device 11. The induction device 11 is provided with a second coil induction module 12, and the laptop computer 1 is also provided with a power management module (Power Management Unit, PMU) 13 and a battery 14. The power management module 13 is an integrated circuit, which usually includes multiple power management functions, such as voltage adjustment, current monitoring and battery management. The PMU is responsible for coordinating and managing all power requirements of the laptop computer 1 to ensure that the laptop computer 1 can operate stably under various working conditions. The internal structure of the battery 14 mainly includes a battery cell and a charge and discharge control circuit board. The battery cell is the energy center of the battery, and the battery cell is responsible for charging and discharging. The charge and discharge control circuit board is used to control the discharge of the battery cell, allowing charging when the battery cell is out of power, and cutting off charging when the battery cell is fully charged.

[0022] The wireless charging device 2 is provided on the laptop computer 1. The wireless charging device 2 is provided with a power module 21, a first coil induction module 22 and a controller 23, and the power module 21 is electrically connected to the first coil induction module 22 and the controller 23 respectively. The controller 23 may have a memory storing a plurality of setting parameters, and the plurality of setting parameters include: high power charging time, normal power charging time and low power charging time. The controller 23 will adjust the transmission power generated by the power module 21 accordingly according to the high power charging time, normal power charging time and low power charging time. When the first coil induction module 22 performs wireless charging operation on the laptop computer 1 by the wireless charging device 2, the controller 23 adjusts the transmission power generated by the power module 21, so that the first coil induction module 22 transmits a wireless charging signal with a specified power to the second coil induction module 12 of the laptop computer 1 after receiving the transmission power.

[0023] The solid-state battery 3 is electrically connected to the wireless charging device 2. The solid-state battery 3 can be electrically connected to the wireless charging device 2 via a cable. The solid-state battery 3 can be an oxide-based solid-state battery, a sulfide-based solid-state battery, or a polymer-based solid-state battery. Because the solid-state battery 3 uses a solid electrolyte, there is no leakage pollution, flammability, explosion, and other problems, and it has a high safety feature. Due to the safety of the solid-state battery, the positive and negative electrodes can use materials with higher energy density, have higher battery storage energy, fast charging and discharging speed, and have the advantage of being more compact.

[0024] See also Figure 2 , Figure 4 and Figure 5As shown, when the user brings the sensing device 11 of the laptop computer 1 into contact with the wireless charging device 2, a magnetic flux is generated between the second coil sensing module 12 of the sensing device 11 and the first coil sensing module 22 of the wireless charging device 2. At the same time, the first coil sensing module 22, the second coil sensing module 12 and the power management module 13 start to wirelessly charge the battery 14 of the laptop computer 1. When the battery 14 is charged to 100%, the power management module 13 stops charging the battery 14.

[0025] In this way, the user can contact the sensing device 11 of the laptop computer 1 with the wireless charging device 2, and the wireless charging device 2 is electrically connected to the solid-state battery 3, wherein the sensing device 11 is provided with a second coil sensing module 12 and the wireless charging device 2 is provided with a first coil sensing module 22, which are coupled with each other so that the power of the solid-state battery 3 can be used to wirelessly charge the laptop computer 1.
