[0024] See also Figure 1-2 ,in Figure 2The middle part of the transmission member 3 is cut away to reveal the structure below. The embodiment of the utility model provides a retractable data cable, including: a housing 1, a winding wheel, a gear 2, a transmission member 3, a driving member, a connecting member and a sliding structure; the data cable is wound around the outer peripheral side of the winding wheel, the winding wheel is connected to the housing 1 along a first rotating axis, and the winding wheel is provided with a coil spring; the winding wheel is used to drive the gear 2 to rotate coaxially; the transmission member 3 is connected to the gear 2 in a transmission manner so that the transmission member 3 is connected to the housing 1 along a second rotating axis; the connecting member is connected to the transmission member 3, and the transmission member 3 is used to move the connecting member along the sliding structure; the sliding structure is provided with a plurality of locking positions, and during the rotation of the transmission member 3, when the connecting member moves to the locking position, the connecting member and the sliding structure are used to limit the transmission member 3 from continuing to rotate in the rotation direction; the driving member is connected to the transmission member 3, and the driving member is used to provide a force to rotate the transmission member 3 in the first direction.

[0025] Specifically, in some embodiments, the sliding structure can be provided on the housing 1, one end of the connecting member is connected to the sliding structure of the housing 1, and is set as the moving end; the other end of the connecting member is fixedly connected to the transmission member 3, and is set as the fixed end. When the transmission member 3 rotates, the transmission member 3 drives the fixed end of the connecting member to move synchronously, thereby realizing the movement of the moving end of the connecting member in the sliding structure of the housing 1.

[0026] In some embodiments, the sliding structure can be provided on the transmission member 3, one end of the connecting member is fixedly connected to the housing 1, and is set as a fixed end; the other end of the connecting member is connected to the sliding structure of the transmission member 3, and is set as a moving end. When the transmission member 3 rotates, the fixed end of the connecting member remains stationary on the housing 1, and the moving end of the connecting member and the transmission member 3 are relatively displaced, so that the moving end of the connecting member moves on the sliding structure of the transmission member 3.

[0027] In the embodiment of the utility model, the data line is wound around the outer peripheral side of the winding wheel, so when the data line is pulled out of the housing 1, the winding wheel and the gear 2 can be driven to rotate relative to the housing 1. At the same time, the gear 2 drives the transmission member 3 to rotate, and the transmission member 3 can drive the connecting member to move along the sliding structure. In the process of pulling the data line, there may be two situations: the connecting member moves to the locking position, and due to the action of the connecting member, the transmission member 3 cannot continue to rotate in the rotation direction, so that the gear 2 cannot continue to rotate in the rotation direction due to the action of the transmission member 3, and the winding wheel cannot continue to rotate in the rotation direction, and the data line cannot continue to be pulled. At this time, the data line can be released to unlock; or after the data line is pulled to a certain length, the connecting member has not moved to the locking position, and the data line is released halfway. After the data line is released, since there is no external force acting on the data line, the transmission member 3 rotates in the opposite direction under the action of the driving member; the gear 2 and the winding wheel also rotate in the opposite direction under the action of the transmission member 3 and the reset force of the coil spring, and the data line automatically retracts. During the automatic retraction of the data cable, when the connecting member moves to another locking position, due to the action of the connecting member, the transmission member 3 cannot rotate along the rotation direction (the rotation direction refers to the rotation direction of the transmission member 3 when the data cable is loosened, that is, the opposite direction of the rotation direction of the transmission member 3 when the data cable is pulled), so that the gear 2 cannot continue to rotate along the rotation direction (the rotation direction refers to the rotation direction of the gear 2 when the data cable is loosened, that is, the opposite direction of the rotation direction of the gear 2 when the data cable is pulled) due to the action of the transmission member 3, and the winding wheel also cannot continue to rotate along the rotation direction (the rotation direction refers to the rotation direction of the winding wheel when the data cable is loosened, that is, the opposite direction of the rotation direction of the winding wheel when the data cable is pulled), the data cable can be partially retracted, and the entire device can be locked. When unlocking, the data line can be pulled to make the winding wheel and the gear 2 rotate in the opposite direction (the opposite direction refers to the opposite direction of the rotation direction of the winding wheel and the gear 2 when the data line is released), and the transmission member 3 is also driven by the gear 2 to rotate in the opposite direction (the opposite direction refers to the opposite direction of the rotation direction of the transmission member 3 when the data line is released). That is, unlocking can be achieved by pulling the data line again. The utility model can realize the extension and locking of the data line. The whole process only needs to pull or release the data line, and there is no need to set a switch structure or operate the switch structure. The structure is simple and easy to operate.

[0028] Further, in some embodiments, the sliding structure is provided on the housing 1, the connecting member includes a connecting rod 5, the connecting rod 5 is provided with a first fixing structure, the transmission member 3 is provided with a second fixing structure, and the first fixing structure is connected to the second fixing structure. Through the first fixing structure and the second fixing structure, the fixed end of the connecting rod 5 can be stably assembled on the transmission member 3. During the rotation of the transmission member 3, the transmission member 3 can drive the connecting rod 5 to move in the sliding structure of the housing 1.

[0029] In some embodiments, the sliding structure is provided on the transmission member, and the second fixed structure is provided on the housing 1. Similarly, through the first fixed structure and the second fixed structure, the fixed end of the connecting rod 5 can be stably assembled on the housing 1. During the rotation of the transmission member 3, the transmission member 3 and the moving end of the connecting rod 5 are relatively displaced, so that the connecting rod 5 moves in the sliding structure of the transmission member 3.

[0030] Furthermore, in some embodiments, the first fixing structure includes a limiting column arranged at one end of the connecting rod 5, and the second fixing structure includes an assembly hole opened in the transmission member 3 or the housing 1, the limiting column is passed through the assembly hole, and the outer peripheral side of the limiting column abuts against the hole wall of the assembly hole.

[0031] Specifically, the connecting rod 5 includes a rod body, and a limiting column arranged at the end of the rod body and perpendicular to the rod body. The limiting column can be in a column shape, and the extension direction of the assembly hole is perpendicular to the rod body. The limiting column is inserted into the assembly hole, and the outer peripheral side of the limiting column abuts against the hole wall of the assembly hole, so that the limiting column can be stably assembled in the assembly hole, so as to achieve stable assembly of the fixed end of the connecting rod 5 and the transmission member 3 or the housing 1.

[0032] In some embodiments, the first fixing structure and the second fixing structure can be assembled and connected by a detachable method such as snap connection, bonding, etc.

[0033] Further, in some embodiments, the driving member is an elastic member, the housing 1 is provided with an assembly structure, the elastic member is assembled on the assembly structure and connected to the transmission member 3, and the elastic member is used to provide a reset force to rotate the transmission member 3 along the first direction.

[0034] Assume that the opposite direction of the first direction is the second direction. When the data cable is pulled, the gear 2 drives the transmission member 3 to rotate in the second direction, and the elastic member is compressed. When the data cable is released, the elastic member provides a reset force for the transmission member 3, so that the transmission member 3 rotates in the opposite direction of the second direction (the first direction). The winding wheel and the gear 2 are acted upon by the transmission member 3 and the winding spring, and rotate in the opposite direction of the original rotation direction, thereby realizing automatic retraction of the data cable.

[0035] It should be noted that the first direction may be clockwise, and the second direction may be counterclockwise; or the first direction may be counterclockwise, and the second direction may be clockwise.

[0036] In other embodiments, the driving member may be a magnet, and the transmission member 3 may be caused to rotate along the first direction through magnetic attraction.

[0037] Further, the elastic member is a torsion spring 4, and the assembly structure includes a convex column protruding from the housing 1. The torsion spring 4 includes a main body 41, and the main body 41 is sleeved outside the convex column. Specifically, the main body 41 is a spirally formed part of the torsion spring 4, which is a hollow structure. The main body 41 is sleeved on the convex column, so that the torsion spring 4 can be positioned on the housing 1. The housing 1 is also provided with other structures that abut against the convex column, so that the torsion spring 4 can be assembled on the housing 1.

[0038] Furthermore, the torsion spring 4 also includes two connecting parts 42, and the two connecting parts 42 are respectively located on both sides of the main body 41. The shell 1 is also provided with two blocking arms 11, and the torsion spring 4 is located between the two blocking arms 11, wherein one connecting part 42 and one of the blocking arms 11 are located on the same side, and the other connecting part 42 and the other blocking arm 11 are located on the same side; the transmission member 3 is provided with a through hole 31 extending along the circumference of the transmission member 3, and one end of the two connecting parts 42 away from the main body 41 is penetrated through the through hole 31.

[0039] Specifically, the torsion spring 4 spirally forms a main body 41, and the ends of the torsion spring 4 extend outward to form two connecting parts 42, and the extending directions of the two connecting parts 42 are the same. A structure mainly in the form of a (-shaped groove is provided on the shell 1, the boss is located between the V-shaped groove, and the two blocking arms 11 are the two sides of the structure. The transmission member 3 is located above the boss and the blocking arm 11, and the torsion spring 4 is located between the two blocking arms 11. The main body 41 of the torsion spring 4 is sleeved on the boss, and in the initial state of the torsion spring 4, the two connecting parts 42 of the torsion spring 4 can correspondingly abut against the two blocking arms 11. The two connecting parts 42 are provided with a convex strip perpendicular to the main body of the connecting part 42 at one end away from the main body 41, and the two convex strips are both penetrated through the through hole 31. When the data cable is pulled, the gear 2 drives the gear 2 to drive ... During the rotation of the transmission member 3 in the second direction, one end of the hole wall of the through hole 31 abuts against one of the connecting parts 42 and drives the connecting part 42 to move, while the other connecting part 42 abuts against the blocking arm 11 opposite to the hole wall. Therefore, between the hole wall and the blocking arm 11, the two connecting parts 42 are close to each other, and the torsion spring 4 is compressed. When the data line is released, there is no external force, and under the action of the reset force, the connecting part 42 abutting against the hole wall drives the hole wall to move, so that the transmission member 3 is driven to rotate in the first direction, and finally the data line is automatically retracted.

[0040] Furthermore, the transmission member 3 has a protrusion 32 , and a plurality of tooth grooves are arranged at intervals on the circumference of the gear 2 , and the protrusion 32 can abut against the tooth grooves.

[0041] Specifically, in some embodiments, the gear 2 is disposed on one side of the transmission member 3, and the protrusion 32 is disposed on the side of the transmission member 3 close to the gear 2. Therefore, the rotation direction of the winding wheel and the gear 2 is opposite to the rotation direction of the transmission member 3.

[0042] When the data cable is pulled out of the housing 1, the winding wheel and the gear 2 rotate relative to the housing 1 along the first direction. At the same time, the gear 2 drives the transmission member 3 to rotate along the second direction, and the transmission member 3 can drive the connecting member to move along the sliding structure, and the elastic member is compressed. In the process of pulling the data cable, there may be two situations: the connecting member moves to the locking position, and the transmission member 3 cannot continue to rotate along the second direction due to the action of the connecting member, the gear 2 cannot continue to rotate along the first direction due to the action of the transmission member 3, and the winding wheel cannot continue to rotate along the first direction. The data cable cannot be pulled further, and the data cable can be released to unlock; or after the data cable is pulled to a certain length, the connecting member has not moved to the locking position, and the data cable is released halfway. After the data cable is released, since there is no external force acting on the data cable, the transmission member 3 rotates in the opposite direction of the second direction (i.e., the first direction) under the action of the driving member; the gear 2 and the winding wheel rotate in the opposite direction of the first direction (i.e., the second direction) under the action of the transmission member 3 and the reset force of the coil spring, and the data cable automatically retracts. During the automatic retraction of the data cable, when the connecting member moves to another locking position, the transmission member 3 cannot rotate in the first direction due to the action of the connecting member, the gear 2 cannot continue to rotate in the second direction due to the action of the transmission member 3, and the winding wheel cannot continue to rotate in the second direction. The data cable can be partially retracted, and the entire device can be locked. When unlocking, the data cable can be pulled to make the winding wheel and the gear 2 rotate in the opposite direction of the second direction (i.e., the first direction), and the transmission member 3 rotates in the opposite direction of the first direction (i.e., the second direction) driven by the gear 2. That is, unlocking can be achieved by pulling the data cable again. The utility model can realize the extension and locking of the data cable. The entire process only requires pulling or releasing the data cable, and there is no need to set a switch structure or operate the switch structure. The structure is simple and easy to operate.

[0043] It can be understood that in other embodiments, the gear 2 is arranged inside the transmission member 3, and the protrusion 32 is arranged on the inner side of the transmission member 3. At this time, the rotation direction of the winding wheel and the gear 2 is the same as the rotation direction of the transmission member 3. The data cable can also be retracted and locked by pulling or loosening the data cable, which is not elaborated here.

[0044] Furthermore, the connecting member includes a connecting rod 5 , the connecting rod 5 is further provided with a sliding block, the sliding structure includes a sliding groove 6 , and the sliding block can be slidably connected to the sliding groove 6 .

[0045] Specifically, the connecting rod 5 is in a [ shape, one end of which is a fixed end, including a limit column, which is assembled in the assembly hole of the transmission member 3 or the housing 1; the other end is a movable end, including a slider, which can move in the slide groove 6.

[0046] For the embodiment in which the sliding structure can be arranged on the housing 1: when the transmission member 3 rotates, the transmission member 3 can drive the slider to move in the slide groove 6, so that when the slider moves to the locking position of the slide groove 6, the transmission member 3 can be restricted from continuing to rotate in the rotation direction, thereby achieving locking. To unlock, it is only necessary to pull or release the data cable so that the slider moves in the opposite direction and the transmission member 3 rotates in the opposite direction to achieve unlocking.

[0047] For the embodiment in which the sliding structure can be arranged on the transmission member 3: when the transmission member 3 rotates, the transmission member 3 and the movable end of the connecting member are relatively displaced, and the slider can move in the slide groove 6. When the slider moves to the locking position of the slide groove 6, the transmission member 3 can be restricted from continuing to rotate in the rotation direction, so that locking can be achieved. When unlocking, it is only necessary to pull or release the data cable to make the transmission member 3 rotate in the opposite direction, and the transmission member 3 and the slider are relatively displaced again, and the slider is away from the locking position of the slide groove 6, so that unlocking can be achieved.

[0048] Furthermore, the locking position includes a slot provided in the slide slot 6. When the slider moves to the slot during the rotation of the transmission member 3, the slider and the slot are used to limit the transmission member 3 from continuing to rotate in the rotation direction. Specifically, one locking position is provided with one slot. By setting the locking position, the rotation amplitude of the transmission member 3 can be controlled, thereby achieving accurate control of the length of the data line.

[0049] Furthermore, in some embodiments, the slide slot 6 includes four slots, namely a first slot 61, a second slot 62, a third slot 63 and a fourth slot 64. The second slot 62, the third slot 63 and the fourth slot 64 together form a heart-shaped structure, and the first slot 61 is located in the middle of the heart-shaped structure.

[0050] In an implementable manner, the sliding structure can be disposed on the housing 1 , with the first and third slots 61 , 63 opening toward the transmission member 3 , and the second and fourth slots 62 , 64 opening away from the transmission member 3 .

[0051] Specifically, the slide slot 6 also includes a track connected between two adjacent slots. When the transmission member 3 rotates, the transmission member 3 drives the connecting rod 5 to move in the slide slot 6, from one slot to another via the track, to achieve the locking and unlocking process. Take the first direction as counterclockwise and the second direction as clockwise as an example.

[0052] Initially, the protrusion 32 is located in the tooth groove, and the connecting rod 5 is in the first slot 61 .

[0053] Pull the data cable, the winding wheel and the gear 2 rotate counterclockwise, the transmission member 3 rotates clockwise, the torsion spring 4 is compressed, and the connecting rod 5 moves toward the second slot 62. Figure 2As shown in the figure), the transmission member 3 cannot continue to rotate clockwise. Under the action of the transmission member 3, the winding wheel and the gear 2 cannot continue to rotate counterclockwise, and the data cable cannot be pulled further. The device is locked and can be unlocked by loosening the data cable; or, when the connecting rod 5 has not moved to the second slot 62, the user lets go.

[0054] When the data cable is released and no external force acts on the data cable, the torsion spring 4 provides a reset force for the transmission member 3, causing the transmission member 3 to rotate counterclockwise. The winding wheel and the gear 2 are acted upon by the torsion spring and the transmission member 3, and the winding wheel and the gear 2 rotate clockwise. During the counterclockwise rotation of the transmission member 3, the connecting rod 5 moves toward the third slot 63. When the connecting rod 5 moves to the third slot 63, the transmission member 3 cannot continue to rotate counterclockwise. Under the action of the transmission member 3, the winding wheel and the gear 2 cannot continue to rotate clockwise, and the data cable is locked.

[0055] Pull the data cable again, the winding wheel and gear 2 rotate counterclockwise, the transmission member 3 rotates clockwise, the torsion spring 4 is compressed, and the connecting rod 5 moves toward the fourth slot 64. When the connecting rod 5 moves to the fourth slot 64, the transmission member 3 cannot continue to rotate clockwise. Under the action of the transmission member 3, the winding wheel and gear 2 cannot continue to rotate counterclockwise, and the device is locked again.

[0056] The data cable is released again. When no external force acts on the data cable, the torsion spring 4 provides a reset force for the transmission member 3, causing the transmission member 3 to rotate counterclockwise. The winding wheel and the gear 2 are acted upon by the torsion spring and the transmission member 3, and the winding wheel and the gear 2 rotate clockwise. During the counterclockwise rotation of the transmission member 3, the connecting rod 5 moves toward the first slot 61. When the connecting rod 5 moves to the first slot 61, the transmission member 3 cannot continue to rotate counterclockwise. The winding wheel and the gear 2 cannot continue to rotate clockwise due to the action of the transmission member 3, and the data cable is locked.

[0057] It should be noted that the number and position of the slots, as well as the distance between two adjacent slots, can be set according to the movement trajectory of the connecting rod 5 in the actual process. By setting the slots, the rotation range of the transmission member 3 can be limited, thereby limiting the rotation range of the winding wheel, and further limiting the length of the data line pulled out, which can be set according to actual needs and is not specifically limited here.
