Utility Model Content

[0003] In view of this, the utility model provides a power supply device and an electronic device to solve the problem that it is difficult to relatively fix the existing electronic products and the external power supply.

[0004] In a first aspect, the utility model provides a power supply device, comprising:

[0005] a first shell;

[0006] The second shell is independently provided with the first shell, and one side of the second shell in the thickness direction is suitable for being fitted with the back wall of the first shell, wherein the first shell is the shell of the electronic device body, and the second shell is the shell of the external power supply;

[0008] The second suction portion is arranged on one side of the second shell body close to the first shell body in the thickness direction, and the second suction portion is suitable for suction with the first suction portion to position and fix the first shell body and the second shell body.

[0009] Through such an arrangement, the second shell and the first shell are arranged independently of each other, and one side of the second shell in the thickness direction is in contact with the back wall of the first shell; by arranging the first suction portion on the back wall of the first shell, and arranging the second suction portion on the side of the second shell close to the first shell along the thickness direction, the first suction portion and the second suction portion are attracted to each other, so that not only the second shell and the first shell can be positioned to ensure the alignment between the second shell and the first shell, but also the second shell and the first shell can be detachably connected to achieve relative fixation between the second shell and the first shell.

[0010] In an optional embodiment, a first female plug-in socket is disposed on the back wall of the first shell, and a male plug-in socket is disposed on a side of the second shell close to the first shell in the thickness direction, and the male plug-in socket is suitable for buckling with the first female plug-in socket;

[0012] By such an arrangement, a triangle positioning is formed between two groups of the first suction parts and the first plug-in female socket, and a triangle positioning is formed between two groups of the second suction parts and the plug-in male socket.

It only takes tens of seconds to fully charge the supercapacitor, which greatly improves the charging speed and has a certain battery life, making it convenient to charge the electronic device at any time. The supercapacitor is powered by an external power supply, which can provide long-term battery life and can be charged repeatedly, thereby replenishing the power loss of the supercapacitor in time, so that the supercapacitor and the external power supply form a hybrid power supply system to adapt to usage scenarios where charging at any time is inconvenient and meet the battery life requirements of electronic equipment.
