[0021] The following further describes in detail the embodiments of the utility model with reference to the drawings. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0022] As Figure 1 shown, the low-noise PD fast charger includes a fast charger head 1 and a protection component 3. A limiting block 2 is provided on the surface of the fast charger head 1. The limiting adjustment hole 302 and the limiting block 2 are slidably connected, and four groups of the limiting adjustment hole 302 and the limiting block 2 are symmetrically arranged about the central axis of the protective cover 301. The limiting block 2 enables the protective cover 301 to move according to the limiting adjustment hole 302. A power plug 4 is provided at the lower end of the fast charger head 1. A wire winding groove 5 is opened in the middle of the lower end of the protective cover 301. The wire winding groove 5 plays an external limiting role for the stored data cable 8, preventing the data cable 8 from loosening during winding and storage. The protective cover 301 and the wire winding groove 5 are of an integrated structure. A jack 6 is opened at the top of the fast charger head 1, and a large plug 7 is installed inside the jack 6. The end of the large plug 7 is connected to a data cable 8, and the end of the data cable 8 is connected to a small plug 9.

[0023] As Figure 2 shown, the protection component 3 for protecting the power plug 4 from falling is arranged outside the fast charger head 1. The protection component 3 includes a protective cover 301, a limiting adjustment hole 302, a connecting rod 303 and a limiting ring 304. The limiting adjustment hole 302 is opened on the surface of the protective cover 301. The protective cover 301 plays a protective role outside the fast charger head 1 and can also play an external protection role for the power plug 4 when the power plug 4 is not in use, preventing the power plug 4 from being damaged due to accidental dropping of the fast charger head 1. The protective cover 301 and the fast charger head 1 are sleeved and connected, and the protective cover 301 and the limiting adjustment hole 302 are of an integrated structure. A connecting rod 303 is installed inside the lower end of the protective cover 301. The connecting rod 303 is used for the support installation of the limiting ring 304. The end of the connecting rod 303 is connected to the limiting ring 304. The limiting ring 304 moves outside the power plug 4 as the protective cover 301 moves, increasing the protection ability of the power plug 4.

[0024] As Figure 3 shown, an auxiliary component 10 for assisting in the storage of the data cable 8 is arranged outside the protective cover 301. The auxiliary component 10 includes a mounting rod 1001 and an auxiliary rope 1002. The auxiliary rope 1002 is connected to the side of the mounting rod 1001. The auxiliary rope 1002 made of rubber has elasticity by itself. Two auxiliary ropes 1002 are symmetrically arranged about the central axis of the mounting rod 1001, and the shape of the auxiliary rope 1002 is a U shape. When the data cable 8 is stored, the small plug 9 can be limited by the auxiliary rope 1002, further increasing the neatness of the storage of the data cable 8 on the fast charger head 1.

[0025] In summary, for this low-noise PD fast charger, first according to Figure 1-Figure 3, when in use, connect the large plug 7 to the socket 6, connect the electric plug 4 on the fast charging head 1 to the circuit, and connect the small plug 9 to the terminal. When the fast charging head 1 is not in use, move the protective cover 301 to the side of the electric plug 4 outside the fast charging head 1, so that the protective cover 301 can also play an external protection role for the electric plug 4 when the electric plug 4 is not in use, avoiding damage to the electric plug 4 caused by accidental falling of the fast charging head 1. When moving, the limit adjustment hole 302 moves outside the limit block 2, adding the protective cover 301 The moving stability is improved. At the same time, when the protective cover 301 moves, the limiting ring 304 moves outside the electric plug 4 along with the movement of the protective cover 301, thereby increasing the protection capability of the electric plug 4. Then the data cable 8 is stored and wound around the outside of the fast charging head 1. During winding, the winding groove 5 acts as an external limit for the stored data cable 8, thereby preventing the data cable 8 from becoming loose when being wound and stored. After bending, the auxiliary rope 1002 is pulled open to limit the small plug 9, thereby further increasing the neatness of the storage of the data cable 8 on the fast charging head 1.
