The plug-in assembly 21 is mounted on the shell 10 and includes a fixing seat 211, a guide seat 212, a plug-in sheet 213, a conductive spring sheet 214 and a transformer 215. The fixing seat 211 is connected with the shell 10 and forms a rotating groove with the shell 10. The guide seat 212 is rotationally connected with the rotating groove and has a positioning surface 216. The plug-in sheet 213 is connected with the guide seat 212 and is used to electrically contact with the conductive spring sheet 214. The conductive spring sheet 214 is electrically connected with the transformer 215 and is used to provide a vertical elastic force for the plug-in sheet 213. The transformer 215 is electrically connected with the conductive disc 22. The upper shell 11 of the shell 10 is provided with a receiving groove 111. When the conductive spring sheet 214 is in abutment with the guide seat 212, an end of the plug-in sheet 213 away from the conductive spring sheet 214 is received in the receiving groove 111. When the conductive spring sheet 214 is in abutment with the plug-in sheet 213, the end of the plug-in sheet 213 away from the conductive spring sheet 214 is separated from the receiving groove 111. In addition, the power receiving mechanism 20 further includes a switching assembly 24 mounted in the shell 10. The switching assembly 24 is provided with a power receiving port 241 and is electrically connected with the plug-in assembly 21.

[0042] As shown in Figure 4 , the conductive disc 22 is mounted on the shell 10 and is provided with a conductive surface 221. The power receiving disc 23 is mounted on the rotating disc 31 and is electrically connected with the conductive surface 221 and is used to transmit power to the transmission line 50.

[0043] As shown in Figure 4 , the winding mechanism 30 includes a rotating disc 31 rotationally mounted in the shell 10 and an elastic reset member 32 used to provide an elastic force for resetting the rotating disc 31. The rotating disc 31 is provided with a plurality of positioning grooves 311 around its rotation axis and is used to cooperate with the locking mechanism 40 to realize positioning of the rotating disc 31. The elastic reset member 32 is a coil spring.

[0044] As shown in Figure 4 , the locking mechanism 40 includes a pawl 41, a locking wheel 42 and two elastic members 43. One end of the pawl 41 is rotationally connected with the shell 10 and the other end is clamped with one of the positioning grooves 311. The locking wheel 42 is rotationally mounted on the shell 10. The two elastic members 43 are connected with the pawl 41 on opposite sides around the rotation direction and are used to provide an elastic force for the pawl 41 to cooperate with the locking wheel 42 to lock the rotating disc 31. Figures 5-6As shown, the pawl 41 comprises a swing block 411, a locking tongue 412 and two guide columns 413. The swing block 411 is rotationally connected with the shell 10. The locking tongue 412 is arranged at one end of the swing block 411 close to the rotating disc 31 and is used for clamping with the positioning groove 311. The two guide columns 413 are arranged at opposite sides of the swing block 411 around the rotating direction respectively. The distance between the two guide columns 413 and the locking tongue 412 is the same. The intersection of the extension directions of the two guide columns 413 coincides with the straight line connected by the rotating shafts of the locking tongue 412 and the swing block 411. Each telescopic elastic member 43 is sleeved with each guide column 413. The telescopic elastic member 43 is a coil spring and is sleeved on the guide column 413. The bottom shell 13 of the shell 10 is provided with mounting grooves 131 for mounting the telescopic elastic members 43. Each mounting groove 131 has a guide surface 132 for abutting the telescopic elastic member 43. The intersection of the perpendicular lines of the guide surfaces 132 coincides with the straight line connected by the rotating shafts of the rotating disc 31 and the swing block 411. The distance between the two guide columns 413 and the locking tongue 412 is the same. The intersection of the extension directions of the two guide columns 413 coincides with the straight line connected by the rotating shafts of the locking tongue 412 and the swing block 411. Each telescopic elastic member 43 is sleeved with each guide column 413. The intersection of the perpendicular lines of the guide surfaces 132 coincides with the straight line connected by the rotating shafts of the rotating disc 31 and the swing block 411. The above-mentioned mode is beneficial to applying the same force to the opposite sides of the swing block 411 by the telescopic elastic members 43. When the swing block 411 swings to one side of the telescopic elastic members 43, the telescopic elastic member 43 is compressed and provides the elastic force for resetting the swing block 411 through the guide surface 132. The locking tongue 412 on the swing block 411 is on the straight line connected by the rotating shafts of the rotating disc 31 and the swing block 411. When the locking tongue 412 on the swing block 411 is on the straight line connected by the rotating shafts of the rotating disc 31 and the swing block 411, the swing block 411 swings to the other side of the telescopic elastic members 43 under the action of inertia and the swing range of the swing block 411 is supported by the other telescopic elastic member 43. Thus, the locking tongue 412 on the swing block 411 can be quickly reset and the locking tongue 412 can be stably inserted into the positioning groove 311. The clamping sensitivity of the locking mechanism 40 is improved.

[0045] wherein, as Figure 6As shown, the intersection point of each guide column 413 and the straight line connecting the rotation axis of the locking tongue 412 and the swing block 411 is inclined to the direction of the rotation axis of the swing block 411, and the intersection point of the perpendicular line of each guide surface 132 and the straight line connecting the rotation axis of the locking tongue 412 and the swing block 411 is inclined to the direction of the rotation axis of the swing block 411. With the layout, the space occupied by the elastic member 43 and the pawl 41 can be effectively reduced, the influence on the swing angle of the pawl 41 can be reduced, and the pawl 41 can be effectively provided with a reset elastic force.

[0046] As shown in Figure 7 , the swing block 411 includes a carrier sheet 414 and two top teeth 415. The carrier sheet 414 is rotatably installed on the shell 10 and connected with the locking tongue 412 and the guide columns 413. The two top teeth 415 are arranged on both sides of the locking wheel 42 and used for abutting against the locking wheel 42.

[0047] Please refer to Figure 1 for reference Figure 2 , the transmission line 50 is wound on the rotating disc 31 and used for receiving the power provided by the power receiving mechanism 20. The transmission line 50 includes a wire 51 and a plug 52. The wire 51 is wound on the rotating disc 31. The bottom shell 13 of the shell 10 is provided with a clamping groove 133 for accommodating the plug 52, so that the entire charging adapter 100 is an integral whole, thereby ensuring the flatness of the appearance of the charging adapter 100 and achieving the purpose of improving the carrying convenience of the charging adapter 100.
