Description

A charging head capable of steplessly storing data cables Technical Field

[0001] The present invention relates to the field of charging heads, and in particular to a charging head capable of steplessly accommodating a data cable. Background Art

[0002] With the increasing popularity and widespread use of mobile phones, mobile phone chargers have become products that can be seen everywhere in daily life. Traditional mobile phone charging plugs need to be used with a data cable. The data cable is long and inconvenient to store. Therefore, some retractable data cables or charging heads that can retract data cables have appeared on the market. The principle is to wind the data cable around a storage shaft. When in use, the data cable is pulled out. When not in use, the storage action is performed by pressing the switch button, etc., and the winding spring technology is used to drive the storage shaft to rotate and retract the cable, and then the data cable is retracted. However, this existing storage technology has some shortcomings, such as: 1. Although the data cable can be stored, after the storage is completed, the USB interfaces set at both ends of the data cable are still left outside, and the place where the data cable is most likely to be damaged is the connection between the USB interface and the data cable, and The reason why it is easy to break is that the connection between the USB interface and the data cable is excessively bent and crushed. In other words, the existing storage technology only plays a storage role and solves the problem of disorderly storage of data cables. When the data cable is carried and used, the connection between the USB interface and the data cable is still prone to being crushed, bent and damaged; secondly, the USB interface and the data cable are connected by an outer layer of outer skin. As the data cable is continuously pulled out, the compression of the coil spring becomes greater. Therefore, the further back, the greater the force required to pull out the data cable. People are generally accustomed to pinching the USB interface to pull the data cable outward. Therefore, as the data cable is pulled out longer, the greater the force on the connection between the USB interface and the data cable, the greater the fatigue damage caused to the connection, which greatly reduces the life of the connection between the USB interface and the data cable.

[0003] Based on the above, the present invention proposes a charging head that can steplessly accommodate a data cable. Summary of the Invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides a charging head that can steplessly accommodate a data cable.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows.

[0006] A charging head capable of steplessly storing a data cable comprises a charging head, the charging head comprising a charging head housing, the charging head housing having an opening on one side along a thickness direction and a detachable shell cover, a partition provided within the charging head housing, an area located on a side of the partition away from a metal pin of the charging head being designated as a storage area, and a data cable being stored in the storage area via a storage mechanism;

[0007] The storage mechanism includes a storage component and a trigger component. The storage component includes a rotating body and a driving component for driving the rotating body to rotate. The storage component is configured to switch between a storage state and an idling state. When in the storage state, the driving component actively drives the rotating body to rotate to retract the data cable. When in the idling state, the driving component is disconnected from the rotating body. In the initial state, the USB interface 1 and the USB interface 2 of the data cable are both located inside the charging head housing.

[0008] The trigger component is used to be manually pressed by the user to extend the USB interface 2 of the data cable and simultaneously switch the storage component to an idle state.

[0009] Furthermore, the axis of the rotating body is parallel to the thickness direction of the charging head housing, and the rotating body includes a rotating shaft and rotating disks arranged at both ends of the rotating shaft;

[0010] The storage component also includes a pressing frame hingedly arranged in the storage area, and the hinge axis formed at the hinge is parallel to the rotating body. A rotating rod is installed at one end of the pressing frame. The rotating rod is parallel to the rotating body and is located on the side of the rotating body away from the partition. An elastic sheet is also provided in the storage area and is located on the side of the pressing frame away from the rotating body. One end of the elastic sheet is connected to the side wall of the storage area and the other end is connected to the pressing frame. There are two groups of pressing frames and they are symmetrically distributed on both sides of the rotating body. The distance between the rotating rod and the rotating axis is greater than the outer diameter of the data cable.

[0011] Furthermore, a slot and an avoidance hole are provided on the end surface of the rotating disk of the rotating body, the avoidance hole is connected to the slot, the avoidance hole penetrates the thickness of the rotating disk, and the avoidance hole penetrates to the outer circumferential surface of the rotating disk;

[0013] Furthermore, the interior of the rotating shaft of the rotating body is hollow and is provided with a motor frame, which is connected to the storage area. A motor is installed on the motor frame. The power connection between the motor and the rotating body is achieved through a planetary reducer. The sun gear of the planetary reducer is installed on the output shaft of the motor by a spline method, and when the sun gear moves axially, the motor continuously outputs power toward the sun gear. A spring is provided between the sun gear and the motor casing, and a protruding pin extends from the end face of the sun gear away from the motor.

[0014] Furthermore, a button for controlling the start of the motor is provided on the outer surface of the charging head housing.

[0015] Furthermore, the trigger component is arranged on the side of the storage component away from the partition, and the charging head shell is provided with an inlet and outlet for the USB interface 2 for the data cable to enter and exit along the length direction and on the side away from the metal pin of the charging head.

[0016] Furthermore, the trigger component includes a pop-up rack slidably installed in the storage area through a guide rod 1, and a disconnect rack slidably installed in the storage area through a guide rod 2. The sliding direction of the pop-up rack and the sliding direction of the disconnect rack are both parallel to the length direction of the charging head housing, and the disconnect rack is located on the side of the pop-up rack facing the rotating body. The pop-up rack is close to the inlet and outlet and is provided with an avoidance opening that is in the same straight line as the inlet and outlet. In the initial state, the USB interface 2 of the data cable is located between the pop-up rack and the inlet and outlet, and the USB interface 2 is in contact with the pop-up rack;

[0017] The outer sleeve of the guide rod 1 is provided with a spring 2 for elastically driving the ejection frame away from the inlet and outlet, and the outer sleeve of the guide rod 2 is provided with a spring 3 for elastically driving the disconnection frame toward the ejection frame.

[0018] Furthermore, the pop-up frame is provided with an inclined surface 1, and the inclined surface 1 is provided with two groups, and the distance between the two groups of inclined surfaces 1 increases along the length direction of the charging head housing and in the direction from the disconnection frame to the pop-up frame;

[0019] The disconnect frame is provided with a second inclined plane, which is provided with two groups. The distance between the two groups of inclined planes decreases along the length direction of the charging head housing and in the direction from the disconnect frame to the ejection frame. The disconnect frame is also provided with a fifth inclined plane, which contacts the convex pin. The distance between the fifth inclined plane and the sun gear decreases along the length direction of the charging head housing and in the direction from the disconnect frame to the ejection frame.

[0020] The first inclined surface and the second inclined surface are arranged to face each other, and a pressing component is provided between the first inclined surface and the second inclined surface.

[0021] Furthermore, the charging head shell is provided with through holes on both sides along the width direction, and the pressing assembly includes an extrusion block slidably installed in the storage area, the sliding direction of the extrusion block is parallel to the width direction of the charging head shell, and the extrusion block is provided with a slope three that fits with the slope one and a slope four that fits with the slope two. The end of the extrusion block extends out of the charging head shell through the through hole and is provided with a pressing block.

[0022] Furthermore, it also includes a current sensor for monitoring the magnitude of the motor current.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention integrates the data cable into the charging head and can store the data cable. In addition, the present invention can also protect the connection between the data cable and the USB interface. Specifically:

[0025] First, when the data cable is stored, the USB ports at both ends are located inside the charging head, so the data cable can be protected during daily use. This solves the problem mentioned in the background art that the connection between the USB port and the data cable is exposed when the data cable is carried and is still prone to being pressed, bent and damaged;

[0026] 2. When pulling out the data cable:

[0027] 1. On the one hand, the sum of the resistance to the rotation of the gear ring inside the planetary reducer and the resistance to the rotation of the motor output shaft is relatively large. On the other hand, the data cable finally wound on the rotating body is loose and has a margin. On the other hand, the length of the USB interface 2 itself is relatively short. Therefore, in the process of pushing the USB interface 2 out, the data cable will push the rotating rod in contact with it to deflect, thereby causing the corresponding holding frame to deflect and the elastic sheet to be compressed. In other words, in the process of pushing the USB interface 2 out, the resistance encountered comes from the elastic sheet, and the elastic sheet is only used to constrain the rotating rod on the holding frame to approach the rotating body. Its own elastic coefficient is small, and the feedback resistance is small. Therefore, the force experienced at the connection between the data cable and the USB interface 2 is approximately equal to the elastic force of the compressed elastic sheet, which is very small.

[0028] 2. When the USB port 2 is ejected, the power transmission path of the planetary reducer is cut off. The resistance to the rotation of the gear ring inside the planetary reducer and the resistance to the rotation of the motor output shaft will not be fed back to the rotating body. In other words, when the data cable is subsequently pulled out, the resistance is very small and constant. Therefore, the force applied to the connection between the data cable and the USB port 2 is very small.

[0029] Combining 1 and 2, it can be seen that during the use of this charging head, no excessive force is applied to the connection between the data cable and the USB interface 2, and no significant damage is caused to the connection. This solves the problem mentioned in the background art that "as the data cable is pulled out longer, the force applied to the connection between the USB interface and the data cable increases, causing greater fatigue damage to the connection, greatly reducing the life of the connection between the USB interface and the data cable."

[0030] In addition, 3. After pulling out the preset length of the data cable, release the trigger component and the planetary reducer resumes the power transmission state. At this time, due to the resistance of the gear ring rotation inside the planetary reducer and the resistance of the motor output shaft rotation, it takes a lot of effort to pull the data cable out further. In other words, the data cable can be limited to the current length;

[0031] 3. When retracting the data cable, if there is an obstacle on the retraction path, the motor load will increase, the current will increase, and the current sensor will sense it, and send a signal to make the motor run in the reverse direction for a preset number of turns and then stop. In other words, the connection between the data cable and the USB will not be subjected to continuous force.

[0032] In summary, the present invention not only realizes the storage of data cables, but also can protect the connection between the data cables and the USB interface. The connection is where the data cables are easily damaged. The most common cause of damage is that the connection is pulled by force and subjected to excessive bending. The present invention can solve these problems. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0048] In the attached drawings of this solution, a refers to the data cable. In the prior art, a USB interface is provided at each end of the data cable, one for connecting to the charging head and the other for connecting to the mobile phone. In order to distinguish the two, the former is named USB interface 1 and the latter is named USB interface 2.

[0049] For environmental protection, the charging head shell in this solution can be made of degradable material such as wheat straw, the data cable can be made of degradable cork material, and the USB interface of the data cable is set according to the type of mobile phone. All of these can be achieved with existing technology and will not be elaborated on.

[0050] In this solution, stepless storage means that longer data cables can be stored. In the existing technology, the data cables that can be stored are generally 1m, 1.5m, etc. In this solution, the volume of the storage area can be increased and more layers can be wrapped around the outside of the rotating body to accommodate longer data cables.

[0051] As shown in Figures 1 to 9, a charging head capable of steplessly storing a data cable comprises a charging head and a data cable integrated into the charging head via a storage mechanism, wherein:

[0052] As shown in Figures 1 to 3, the charging head includes a charging head shell 100. The charging head shell 100 is open on one side along the thickness direction and is detachably mounted with a shell cover 101. For example, a pin is provided on the shell cover 101, and a socket is provided on the charging head shell 100. The pin and the socket form an interference fit. The shell cover 101 can be buckled off the charging head shell 100, or the shell cover 101 can be re-closed on the charging head shell 100. This is achievable with the existing technology and will not be elaborated on. In addition, a partition 102 is provided in the charging head shell 100. The side of the partition 102 facing away from the metal pins of the charging head is in an arc shape. The partition 102 divides the charging head shell 100 into two parts. One part is close to the metal pins of the charging head and is used to install electrical components related to the existing charging head technology, and the other part is away from the metal pins of the charging head and is used to install a storage mechanism, which is named the storage area.

[0053] As shown in Figures 3 to 5, the storage mechanism includes a storage component 200 and a trigger component 300. The storage component 200 is configured to switch between a storage state and an idle state. When in the storage state, the storage component 200 actively rotates to reel in the data cable. When in the idle state, the storage component 200 passively rotates to release the data cable, and during the release process, the storage component 200 does not hinder the release of the data cable. In addition, in the initial state, the USB interface 1 and the USB interface 2 of the data cable are both located inside the charging head housing 100; the trigger component 300 is used to be manually pressed by the user to extend the USB interface 2 of the data cable, and at the same time switch the storage component 200 to the idle state.

[0054] Specifically, as shown in FIG. 4 to FIG. 8 , the storage component 200:

[0055] As shown in Figure 6, the storage component 200 includes a rotating body 201 installed in the storage area along the thickness direction of the charging head housing 100. Furthermore, the rotating body 201 is close to the arc surface of the partition 102, and the rotating body 201 includes a rotating axis and rotating disks arranged at both ends of the rotating axis.

[0056] The storage component 200 also includes a pressing frame 205 hingedly arranged in the storage area. The hinge axis formed at the hinge is parallel to the rotating body 201. A rotating rod 206 is installed at one end of the pressing frame 205. The rotating rod 206 is parallel to the rotating body 201 and is located on the side of the rotating body 201 away from the partition 102. An elastic sheet 207 is also provided in the storage area and is located on the side of the pressing frame 205 away from the rotating body 201. One end of the elastic sheet 207 is connected to the side wall of the storage area and the other end is connected to the pressing frame 205.

[0057] There are two sets of holding frames 205 symmetrically distributed on both sides of the rotating body 201. There are two sets of rotating rods 206 and elastic sheets 207 respectively. In the initial state, the distance between the rotating rods 206 and the rotating axis of the rotating body 201 is slightly larger than the outer diameter of the data cable.

[0058] The end surface of the rotating disk of the rotating body 201 is provided with a slot 202 and an avoidance hole 204 . The avoidance hole 204 is communicated with the slot 202 . The avoidance hole 204 passes through the thickness of the rotating disk and passes through the outer circumference of the rotating disk.

[0059] A socket 203 is installed in the slot 202, and the socket 203 is used to be plugged into the USB interface 1 of the data cable. Furthermore, in order to make the plugging more convenient, the socket 203 shell is set to be rotatable. In this way, the socket 203 can be picked up with your fingers so that the end of it extends out of the slot 202, and then the USB interface 1 of the data cable is plugged into it, which makes the plugging more convenient. In addition, a coil spring should be provided at the installation place of the socket 203. After the plugging is completed, let go, and the coil spring can reset the socket 203 and lie flat in the slot 202. As for the connection between the socket 203 and the metal pin of the charging head, it can be achieved by existing technology and will not be elaborated on.

[0060] As shown in FIG6 , the winding process of the data line on the rotating body 201 is specifically as follows:

[0061] First, buckle down the cover 101, connect the USB port 1 of the data cable to the socket 203, and then pass the data cable through the avoidance hole 204;

[0062] Then, the rotating body 201 rotates to reel in the data line, and the data line is wound around the outside of the rotating shaft of the rotating body 201. During the winding process, due to the presence of the rotating rod 206, the data line is pressed by the rotating rod 206 to be wound around the outside of the rotating shaft. Since the distance between the rotating rod 206 and the rotating shaft of the rotating body 201 is slightly larger than the outer diameter of the data line, after the rotating shaft rotates one circle, the remaining data line comes into contact with the data line wound around the outside of the rotating shaft, and the two are squeezed. The remaining data line will move to the blank part of the rotating shaft and be wound around the outside of the rotating shaft. That is to say, through the cooperation of the rotating rod 206 and the rotating body 201, the data line can be wound around the outside of the rotating shaft in an orderly manner along the axial direction of the rotating body 201.

[0063] Furthermore, as shown in FIG. 7 and FIG. 8 , the storage member 200 further includes a driving assembly for driving the rotating body 201 to rotate.

[0064] The rotating shaft of the rotating body 201 is hollow and is provided with a motor frame, which is connected to the storage area. A motor 208 is installed on the motor frame. The motor 208 and the rotating body 201 are connected by a power transmission member 209. The power transmission member 209 is a planetary reducer technology. The sun gear 2091 of the planetary reducer is installed on the output shaft of the motor 208 by a spline method, and when the sun gear 2091 moves axially, the motor 208 continues to output power toward the sun gear 2091. A spring 210 is provided between the sun gear 2091 and the housing of the motor 208, and a protruding pin 2092 extends from the end face of the sun gear 2091 away from the motor 208.

[0065] In the initial state, the sun gear 2091 is meshed with the planetary gears in the planetary reducer, so that the power transmission member 209 is in the power transmission state. At this time, the motor 208 drives the rotating body 201 to rotate slowly and at a constant speed through the power transmission member 209.

[0066] When the trigger component 300 causes the sun gear 2091 to move and disengage from the planetary gear, the power transmission of the power transmission component 209 is disconnected. At this time, the data cable can be directly pulled outward, and the rotating body 201 rotates to pay out the cable. After the data cable is pulled out to a preset length, the trigger component 300 is released, and the power transmission component 209 resumes the power transmission state. At this time, based on the resistance of the gear ring rotation inside the planetary reducer and the resistance of the output shaft of the motor 208, it takes a lot of effort to pull the data cable outward again, that is, the data cable is limited to the current length.

[0067] Furthermore, as shown in FIG. 1 and FIG. 2 , a button 400 for controlling the start of the motor 208 is provided on the outer surface of the charging head housing 100 .

[0068] Specifically, as shown in FIG4, FIG5 and FIG9, the trigger component 300:

[0069] The trigger component 300 is arranged on the side of the storage component 200 away from the partition 102. In addition, the charging head housing 100 is provided with an inlet and outlet for the USB interface 2 for the data cable to enter and exit along the length direction and on the side away from the metal pins of the charging head.

[0070] The trigger component 300 includes a pop-up rack 301 slidably installed in the storage area through a guide rod 1 302, and a disconnect rack 305 slidably installed in the storage area through a guide rod 2 306, wherein the sliding direction of the pop-up rack 301 and the sliding direction of the disconnect rack 305 are both parallel to the length direction of the charging head housing 100, and the disconnect rack 305 is located on the side of the pop-up rack 301 facing the rotating body 201, the pop-up rack 301 is close to the inlet and outlet, and the pop-up rack 301 is provided with an avoidance opening 304 which is in the same straight line as the inlet and outlet. In the initial state, the USB interface 2 of the data cable is located between the pop-up rack 301 and the inlet and outlet, the USB interface 2 is in contact with the pop-up rack 301, and the avoidance opening 304 is for avoiding the data cable.

[0071] In addition, the outer sleeve of the guide rod 1 302 is provided with a spring 2 303 , whose elastic force drives the ejection frame 301 away from the inlet and outlet; the outer sleeve of the guide rod 2 306 is provided with a spring 307 , whose elastic force drives the disconnection frame 305 close to the ejection frame 301 .

[0072] The pop-up frame 301 is provided with an inclined surface 1, and there are two groups of inclined surfaces 1. The distance between the two groups of inclined surfaces 1 increases along the length direction of the charging head housing 100 and in the direction from the disconnect frame 305 to the pop-up frame 301.

[0073] The disconnect frame 305 is provided with a second inclined surface. There are two groups of the second inclined surface. The distance between the two groups of the second inclined surface decreases along the length direction of the charging head housing 100 and in the direction from the disconnect frame 305 to the eject frame 301.

[0074] The disconnect frame 305 is also provided with a bevel five, which contacts the protruding pin 2092. The distance between the bevel five and the sun gear 2091 decreases along the length direction of the charging head housing 100 and in the direction from the disconnect frame 305 to the pop-up frame 301.

[0075] The first inclined surface and the second inclined surface are arranged to face each other, and a pressing component is provided between the first inclined surface and the second inclined surface, and two groups of pressing components are correspondingly provided.

[0076] Furthermore, the charging head housing 100 is provided with through holes on both sides along the width direction, and the pressing component includes an extrusion block 308 slidably installed in the storage area. The sliding direction of the extrusion block 308 is parallel to the width direction of the charging head housing 100. The extrusion block 308 is provided with a slope three that is in contact with the slope one and a slope four that is in contact with the slope two. The end of the extrusion block 308 extends out of the charging head housing 100 by passing through the through hole, and is provided with a pressing block 309.

[0077] The user presses the pressing block 309 with one hand. During the pressing process, the cooperation of the third bevel and the first bevel drives the pop-up frame 301 close to the inlet and outlet, thereby pushing the USB interface 2 of the data cable out and exposing it to the outside. The cooperation of the fourth bevel and the second bevel drives the disconnection frame 305 to move away from the pop-up frame 301. During the movement of the disconnection frame 305 away from the pop-up frame 301, the fifth bevel pushes the protruding pin 2092, thereby disengaging the sun gear 2091 from the planetary gear, and the power transmission of the power transmission member 209 is disconnected. Then, the user can pinch the USB interface 2 with the other hand and pull the data cable outward.

[0078] Working principle of the present invention:

[0079] 1. Paying off the wire during normal use:

[0080] The user presses the pressing block 309 with one hand. During the pressing process, the third bevel cooperates with the first bevel to drive the ejection frame 301 close to the inlet and outlet, thereby pushing the USB interface 2 of the data cable out and exposing it to the outside. The fourth bevel cooperates with the second bevel to drive the disconnection frame 305 to move away from the ejection frame 301. During the movement of the disconnection frame 305, the fifth bevel pushes the protruding pin 2092, thereby disengaging the sun gear 2091 from the planetary gears, and disconnecting the power transmission member 209. Then, the user can pinch the USB interface 2 with the other hand and pull the data cable outward.

[0081] After the data cable is pulled out to the preset length, the pressure on the pressing block 309 is released, and the sun gear 2091 re-engages with the planetary gear. At this time, due to the large resistance to the rotation of the gear ring inside the planetary reducer and the resistance to the rotation of the output shaft of the motor 208, it takes a lot of effort to pull the data cable out again. In other words, the data cable can be limited to the current length.

[0082] In the above process:

[0083] 1. It should be noted that, as shown in FIG6 , on the one hand, the sum of the resistance to the rotation of the gear ring inside the planetary reducer (i.e., the power transmission member 209) and the resistance to the rotation of the output shaft of the motor 208 is relatively large. On the other hand, the data cable finally wound around the rotating body 201 is loosely wound, with some margin. On the other hand, the length of the USB interface 2 itself is relatively short. Therefore, in the process of pushing the USB interface 2 out, the data cable will push the rotating rod 206 in contact with it to deflect, thereby causing the corresponding holding frame 205 to deflect and the elastic sheet 207 to be compressed. In other words, in the process of pushing the USB interface 2 out, the resistance encountered comes from the elastic sheet 207. The elastic sheet 207 is only used to constrain the rotating rod 206 on the holding frame 205 to approach the rotating body 201. Its own elastic coefficient is relatively small, and the feedback resistance is relatively small. Therefore, the force experienced at the connection between the data cable and the USB interface 2 is approximately equal to the elastic force of the compressed elastic sheet 207, which is very small.

[0084] 2. When the USB port 2 is ejected, the power transmission path of the planetary reducer is cut off. The resistance to the rotation of the gear ring inside the planetary reducer and the resistance to the rotation of the output shaft of the motor 208 will not be fed back to the rotating body 201. In other words, when the data cable is subsequently pulled out, the resistance is very small and constant. Therefore, the force applied to the connection between the data cable and the USB port 2 is very small.

[0085] Combining 1 and 2, it can be seen that during the use of this charging head, no excessive force is applied to the connection between the data cable and the USB interface 2, and no significant damage is caused to the connection. This solves the problem mentioned in the background art that "as the data cable is pulled out longer, the force applied to the connection between the USB interface and the data cable increases, causing greater fatigue damage to the connection, greatly reducing the life of the connection between the USB interface and the data cable."

[0086] 2. Rewinding during normal use:

[0087] Unplug the phone, but keep the charger plugged into the socket.

[0088] Then, the button 400 is pressed to start the motor 208, driving the rotating body 201 to rotate at a constant speed, and the data cable is retracted into the charging head housing 100. Since both USB interfaces of the data cable are inside the charging head housing 100, the problem mentioned in the background art that the connection between the USB interface and the data cable is exposed when the data cable is carried and used, which still exists. The problem that it is easy to bend and damage;

[0089] In addition, it should be noted that in this solution, when the USB interface 2 contacts the pop-up frame 301, due to the restriction of the pop-up frame 301, the load of the motor 208 increases, resulting in a larger current, which is then sensed by the current sensor set on the motherboard and sends a signal to make the motor 208 reverse for a preset number of turns and then stop. The preset number of reverse turns is to offset the movement of the pop-up frame 301 caused by the motor 208 continuing to drive the storage of the data cable after the USB interface 2 contacts the pop-up frame 301, and the spring 2 303 is compressed. If this offset is not achieved, the data cable and the USB interface 2 will be in a state of contact after the storage is completed. The connection will be continuously subjected to the force from the feedback of the second spring 303, and the connection subjected to continuous force will increase the fatigue damage of the connection and reduce the service life of the connection. In addition, after the offset is completed, the reverse operation of the motor 208 will loosen the data cable finally wound on the rotating body 201, leaving a margin, which provides a margin for the ejection process of the USB interface 2 when the charging head is used. In addition, due to the presence of the rotating rod 206, the data cable on the rotating body 201 is pressed and held, so the looseness of the data cable finally wound on the rotating body 201 will not affect the previously wound data cables.

[0090] In addition, it should be noted that in the prior art, the technology of retracting the data cable using a coil spring is generally used. The data cable retracts at a relatively fast speed. If there is an obstacle on the retraction path, the elastic force of the coil spring will still cause the data cable to have a retraction tendency, thereby causing the connection between the data cable and the USB interface to be subjected to a large force, which can easily cause damage to the connection. In this solution, if the data cable encounters an obstacle during the retraction process, it will be sensed and a signal will be sent to cause the motor 208 to run in reverse for a preset number of turns and then stop. In other words, the connection between the data cable and the USB will not be subjected to continuous force.

[0091] 3. In this solution, if the data cable is damaged or there is a problem with the data cable winding process, the shell cover 101 can be removed for replacement or maintenance.
