[0047] As shown in Figure 2 The shell 1 is provided with a charging socket 30 matched with the device to be charged above the first dustproof door 2 and the second dustproof door 3. The charging socket 30 is arranged to facilitate the insertion of the device into the charging base.

[0048] The charging socket 30 is fixedly installed with a leaning plate 4 matched with the device to be charged. The leaning plate 4 is used to provide support for the device to be charged and fix the position of the device during charging.

[0054] The working principle of this utility model is as follows:

[0055] When the device is not plugged into the charging dock for charging, the first torsion spring 17, the second torsion spring 18, the third torsion spring 19, and the fourth torsion spring 20 are all in their natural state, causing the first dustproof door 2 and the second dustproof door 3 to close.

[0056] When the device needs to be charged, place the bottom of the device above the first dustproof door 2 and the second dustproof door 3, and then insert the bottom of the device into the connection between the first dustproof door 2 and the second dustproof door 3. The bottom of the device pushes the first dustproof door 2 and the second dustproof door 3 to rotate towards the center of the base 5. The first interference part 201 drives the torsion arm at one end of the first torsion spring 17 to rotate, and the first torsion spring 17 enters the retracted state.

The fourth interference part 302 drives the torsion arm at one end of the fourth torsion spring 20 to rotate, and the fourth torsion spring 20 enters the retracted state.

[0057] When the device is fully charged and removed from the charging dock, the elastic restoring force of the first torsion spring 17 pushes the first interference part 201 to rotate, the elastic restoring force of the third torsion spring 19 pushes the second interference part 202 to rotate, the elastic restoring force of the second torsion spring pushes the third interference part 301 to rotate, and the elastic restoring force of the fourth torsion spring 20 pushes the fourth interference part 302 to rotate, thereby closing the first dustproof door 2 and the second dustproof door 3.
