Compared with the prior art, the invention has the beneficial effects that:
in addition, the invention can realize the protection of the connection part of the data line and the USB interface, and the invention is particularly applicable to the storage of the data line:
1. when the storage is completed, the USB interfaces at the two ends of the data line are all positioned in the charging head, so that the data line can be protected during daily carrying and use, and the problem that the joint of the USB interface and the data line is exposed when the data line is carried and used in the background art and is easy to be bent and damaged is still solved;
2. during the process of pulling out the data line:
1. on one hand, the sum of the resistance of rotation of the gear ring in the planetary reducer and the resistance of rotation of the motor output shaft is larger, on the other hand, the winding of the data wire finally wound on the rotating body is loose, and on the other hand, the length of the USB interface II is shorter, so that in the process of pushing the USB interface II, the data wire can push a rotary rod in contact with the USB interface II to deviate, the corresponding pressing and holding frame deflects, the elastic sheet is compressed, that is, in the process of pushing the USB interface II, the received resistance is derived from the elastic sheet, the elastic sheet is only used for restraining the rotary rod on the pressing and holding frame to be close to the rotating body, the elasticity coefficient of the elastic sheet is smaller, the feedback resistance is smaller, and the force received by the connecting part of the data wire and the USB interface II is approximately equal to the elasticity of the compressed elastic sheet and is very small;
2. when the second USB interface is popped up, the power transmission route of the planetary reducer is cut off, and the resistance of the rotation of the gear ring inside the planetary reducer and the resistance of the rotation of the motor output shaft cannot be fed back to the rotating body, namely, the resistance is very small and is a constant value in the process of pulling out the data line outwards, so that the force born by the joint of the data line and the second USB interface is very small;
as can be seen from comprehensive results 1 and 2, the charging head does not cause excessive force at the connection between the data line and the second USB interface, and thus does not cause larger damage to the connection, which solves the problem that the longer the data line is pulled out, the larger the force at the connection between the USB interface and the data line is, the larger the fatigue damage to the connection is, and the service life of the connection between the USB interface and the data line is greatly reduced in the prior art;
in addition, 3, after the data wire with the preset length is pulled outwards, the triggering component is loosened, and the planetary reducer is restored to the power transmission state again, at the moment, based on the resistance of the rotation of the gear ring inside the planetary reducer and the resistance of the rotation of the motor output shaft, the data wire is required to be pulled outwards again, namely, the data wire can be limited at the current length;
3. in the process of retracting the data wire, if an obstacle exists on the retracting path, the load of the motor is increased, the current is increased, the motor is sensed by the current sensor, and a signal is sent to enable the motor to reversely run for a preset number of turns and then stop, namely, the connection part of the data wire and the USB cannot be subjected to continuous force.
In summary, the invention not only realizes the storage of the data line, but also can protect the connection of the data line and the USB interface, and the connection is the place where the data line is easy to be damaged, and the most common reason for the damage is that the connection is pulled by force and is excessively bent, so that the invention can solve the problems.

the user presses the pressing block 309 by one hand, in the pressing process, the ejection frame 301 is driven to approach the inlet and the outlet through the matching of the inclined plane III and the inclined plane I, so that the USB interface II of the data line is pushed out and exposed, the disconnection frame 305 is driven to move away from the ejection frame 301 through the matching of the inclined plane IV and the inclined plane II, in the moving process of the disconnection frame 305 away from the ejection frame, the sun gear 2091 is disengaged from the planetary gear through the pushing of the inclined plane V against the protruding pin 2092, the power transmission of the power transmission piece 209 is disconnected, and then the other hand of the user can pinch the USB interface II and pull the data line outwards;
after the data line is pulled out by a predetermined length, the pressing of the pressing block 309 is released, and the sun gear 2091 is re-engaged with the planetary gear, at this time, the resistance based on the rotation of the gear ring inside the planetary reducer and the resistance based on the rotation of the output shaft of the motor 208 are large, so that it takes a great deal of effort to pull the data line outward, that is, the data line can be limited to the current length.
In the above process:
1. it should be noted that, as shown in fig. 6, on the one hand, the sum of the resistance of rotation of the gear ring inside the planetary reducer (i.e. the power transmission piece 209) and the resistance of rotation of the output shaft of the motor 208 is larger, on the other hand, the winding of the data wire wound on the rotator 201 is loose, and there is a margin, on the other hand, the length of the USB interface two is shorter, so that in the process of pushing the USB interface two, the data wire pushes the rotating rod 206 in contact with the USB interface two to deflect, and further deflects the corresponding pressing rack 205, the elastic piece 207 is compressed, that is, in the process of pushing the USB interface two to push the USB interface two, the resistance received by the elastic piece 207 is derived from the elastic piece 207, and the elastic piece 207 is only used for restraining the rotating rod 206 on the pressing rack 205 to be close to the rotator 201, the elastic coefficient of itself is smaller, the feedback resistance is smaller, and the elastic force received by the connecting part of the data wire and the USB interface two is approximately equal to the elastic piece 207 after being compressed, which is very small;
2. when the second USB interface is popped up, the power transmission route of the planetary reducer is cut off, and the resistance of the rotation of the gear ring inside the planetary reducer and the resistance of the rotation of the output shaft of the motor 208 are not fed back to the rotator 201, that is, the resistance is very small and is a constant value in the process of pulling out the data line outwards, so that the force born by the connection part of the data line and the second USB interface is very small;
as can be seen from comprehensive results 1 and 2, the charging head does not cause excessive force at the connection between the data line and the second USB interface, and thus does not cause larger damage to the connection, which solves the problem that the longer the data line is pulled out, the larger the force at the connection between the USB interface and the data line is, the larger the fatigue damage to the connection is, and the service life of the connection between the USB interface and the data line is greatly reduced in the prior art;
2. wire winding in normal use process:
pulling out the mobile phone, and still inserting the charging head on the power strip or the socket;
then, the button 400 is pressed to start the motor 208, so as to drive the rotator 201 to rotate at a constant speed, and the data wire is retracted into the charging head housing 100, and as the two USB interfaces of the data wire are both positioned in the charging head housing 100, the problem that when the data wire is carried and used in the prior art, the joint of the USB interface and the data wire is exposed, and the problem that the joint is easy to be bent and damaged still exists;
in addition, it should be noted that, in the present solution, after the USB interface two contacts with the pop-up rack 301, due to the limitation of the pop-up rack 301, the load of the motor 208 increases, resulting in current becoming larger, and then being sensed by the current sensor disposed on the motherboard, and sending a signal to cause the motor 208 to reversely run for a preset number of turns, and then stop, the reversely running for counteracting the pop-up rack 301 caused by the USB interface two contacting with the pop-up rack 301, the motor 208 continues to drive the pop-up rack 301 to move, and the spring two 303 is compressed, if not counteracted, the connection between the data line and the USB will continuously receive the force fed back by the spring two 303 after completing the stowing, and the connection will be continuously stressed, resulting in fatigue damage at the connection, reducing the service life of the connection, in addition, after counteracting, the reverse running of the motor 208 will make the data line wound on the rotator 201 at last, there is a margin, providing a margin for the pop-up process of the USB interface two when the charging head is used, and because the data line on the rotator 201 is continuously pressed by the existence of the rotator 206, the data line wound on the rotator 201 will not affect the data line wound at last loose before the winding.
In addition, it should be noted that in the prior art, in the technology of generally adopting the coil spring to retract the data line, the speed of retracting the data line is faster, if there is an obstacle on the retracting path, the elasticity of the coil spring still causes a retracting trend of the data line, so that the connection between the data line and the USB interface is subjected to a larger force, and the connection is easily damaged.
3. In this scheme, if the data line is damaged, or if a problem occurs in the data line winding process, the cover 101 may be fastened down for replacement or maintenance.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
