[0039] Below, combined Figures 1 to 7 , the above-mentioned charging adapter 100 is further explained.

[0040] like Figure 1 to Figure 2 As shown, the shell 10 includes an upper shell 11, a base shell 12 and a bottom shell 13. The upper shell 11 is connected to the base shell 12, the base shell 12 is connected to the power connection mechanism 20, the winding mechanism 30 is rotatably connected to the base shell 12, and the locking mechanism 40 is installed on the bottom shell 13.

[0041] like Figure 3 to Figure 4As shown, the power connection mechanism 20 is installed on the housing 10 and is used to receive power provided by an external power source. The power connection mechanism 20 includes a plug-in assembly 21, a conductive plate 22 and a power connection plate 23. The plug-in assembly 21 is installed on the housing 10, and includes a fixed seat 211, a guide seat 212, a plug-in sheet 213, a conductive spring sheet 214 and a transformer 215. The fixed seat 211 is connected to the housing 10 and forms a rotating groove with the housing 10. The guide seat 212 is rotatably connected to the rotating groove and has a positioning surface 216. The plug-in sheet 213 is connected to the guide seat 212 and is used to electrically contact with the conductive spring sheet 214. The conductive spring sheet 214 is electrically connected to the transformer 215. The transformer 215 is electrically connected to the conductive plate 22, and the upper shell 11 of the housing 10 is provided with a receiving groove 111. When the conductive spring sheet 214 is in contact with the guide seat 212, one 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 contact with the plug-in sheet 213, one 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 connection mechanism 20 also includes a switching assembly 24 installed in the housing 10. The switching assembly 24 is provided with a power connection port 241 and is electrically connected to the plug-in assembly 21.

[0042] like Figure 4 As shown, the conductive disk 22 is mounted on the housing 10 and is provided with a conductive surface 221 . The power receiving disk 23 is mounted on the rotating disk 31 and is in electrical contact with the conductive surface 221 for transmitting power to the transmission line 50 .

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

[0044] like Figure 4 As shown, the locking mechanism 40 includes a pawl 41, a locking wheel 42 and a telescopic elastic member 43. One end of the pawl 41 rotates with the housing 10, and the other end is engaged with one of the positioning grooves 311. The locking wheel 42 is rotatably mounted on the housing 10. There are two telescopic elastic members 43, and each telescopic elastic member 43 is respectively connected to the opposite side of the pawl 41 around the rotation direction, so as to provide elastic force for the pawl 41 to cooperate with the locking wheel 42 to lock the rotating disk 31. Figures 5 and 6As shown, the pawl 41 includes a rocking block 411, a locking tongue 412 and a guide column 413. The rocking block 411 is rotatably connected to the housing 10. The locking tongue 412 is disposed at one end of the rocking block 411 close to the rotating disk 31 and is used to engage with the positioning groove 311. There are two guide columns 413, wherein each guide column 413 is respectively disposed on the opposite side of the rocking block 411 around the rotation direction. The spacing between the two guide columns 413 and the locking tongue 412 is the same, and the intersection point of the extension direction of the two guide columns 413 coincides with the straight line formed by the rotation axis of the locking tongue 412 and the rocking block 411. Each telescopic The elastic member 43 is respectively 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 housing 10 is provided with a mounting groove 131 for mounting each telescopic elastic member 43. Each mounting groove 131 has a guide surface 132 for the telescopic elastic member 43 to abut against. The intersection of the vertical lines of each guide surface 132 coincides with the straight line formed by the rotation axis of the rotating disk 31 and the rotation axis of the swing block 411. The spacing between the two guide columns 413 and the lock tongue 412 is the same, and the intersection of the extension direction of the two guide columns 413 and the lock tongue 412 and the swing block 411 are the same. The straight line formed by the rotation axis of the swing block 411 coincides with each other, and each telescopic elastic member 43 is respectively sleeved with each guide column 413. The intersection of the vertical lines of each guide surface 132 coincides with the straight line formed by the rotation axis of the turntable 31 and the rotation axis of the swing block 411, which is conducive to each telescopic elastic member 43 to apply the same force to the opposite side of the swing block 411. When the swing block 411 swings in the direction of one of the telescopic elastic members 43, the telescopic elastic member 43 is compressed and provides the elastic force for the swing block 411 to reset through the guide surface 132, so that the lock tongue 412 on the swing block 411 is in the rotation state. On the straight line formed by the rotation axis of the disk 31 and the rotation axis of the rocking block 411, when the locking tongue 412 on the rocking block 411 is on the straight line formed by the rotation axis of the turntable 31 and the rotation axis of the rocking block 411, under the action of inertia, the rocking block 411 swings in the direction of the other telescopic elastic member 43, and the swing amplitude of the rocking block 411 is supported by the other telescopic elastic member 43, thereby effectively ensuring that the locking tongue 412 on the rocking block 411 can be quickly reset, so that the locking tongue 412 can be stably inserted into the positioning groove 311, thereby achieving the purpose of improving the stopping sensitivity of the locking mechanism 40.

[0045] Among them, Figure 6As shown, each guide column 413 is inclined toward the direction of the rotation axis of the swing block 411 at the intersection of the straight line formed by the locking tongue 412 and the rotation axis of the swing block 411 around its extension direction, and the vertical line of each guide surface 132 is inclined toward the direction of the rotation axis of the swing block 411 around the intersection of the straight line formed by the locking tongue 412 and the rotation axis of the swing block 411. By adopting this layout, the space occupied by the telescopic elastic member 43 and the pawl 41 can be effectively reduced, while reducing the influence on the swing angle of the pawl 41. At the same time, it can also effectively provide the pawl 41 with its resetting elastic force.

[0046] like Figure 7 As shown, the rocking block 411 includes a carrier 414 and a top tooth 415. The carrier 414 is rotatably mounted on the housing 10 and is connected to the locking tongue 412 and each guide column 413. There are two top teeth 415. The two top teeth 415 are respectively arranged on both sides of the locking wheel 42, and are both used for the locking wheel 42 to resist.

[0047] Please combine Figure 1 refer to Figure 2 The transmission line 50 is wound on the turntable 31 and is used to receive power provided by the power connection mechanism 20. The transmission line 50 includes a wire 51 and a plug 52. The wire 51 is wound on the turntable 31. The bottom shell 13 of the shell 10 is provided with a slot 133 for accommodating the plug 52, so that the entire charging adapter 100 is formed as a 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.

[0048] When the charging adapter 100 shown in the present invention is in use, the plug-in sheet 213 of the plug-in assembly 21 is controlled to drive the guide seat 212 to rotate, so that the plug-in sheet 213 is in a vertical state and is connected to the conductive spring sheet 214, and the plug-in sheet 213 is inserted into an external power socket, and the external power is transmitted to the transmission line 50 through the plug-in assembly 21, the conductive plate 22 and the power connection plate 23; when the transmission line 50 needs to be unfolded, the plug 52 of the transmission line 50 is pulled, and the turntable 31 is pulled to rotate by the wire 51. At this time, the elastic reset member 32 is reeled under force, and the lock tongue 412 of the ratchet 41 is separated from the positioning groove 311 of the turntable 31. When the transmission line 50 is stopped, the elastic reset member 32 loses its locking position. The locking wheel 42 is kept stationary under the locking action of the pawl 41, and the locking wheel 42 cooperates with the pawl 41 to lock the turntable 31 in the corresponding position, thereby realizing the unfolding of the transmission line 50; when the transmission line 50 needs to be wound up, the transmission line 50 is slightly pulled, and the locking tongue 412 of the pawl 41 loses the resistance of the turntable 31, and under the action of the elastic force provided by the telescopic elastic member 43, the pawl 41 is pushed to disengage from the locking wheel 42, and the turntable 31 is rotated and reset under the action of the elastic reset member 32, and the transmission line 50 is wound around the turntable 31 to complete the winding.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
