DETAILED DESCRIPTION

[0073] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0074] In the embodiments of the present application, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, it can be an electrical connection or a connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0075] It should be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order for the objects. It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0076] The following combination Figures 1 to 14The ultra-thin data cable storage device described in the embodiment of the present application is described in detail.

[0077] In an embodiment of the present application, the data cable storage device includes: a housing 100, a rotating member 200, a cable 300, a first elastic member 400 and a limiting assembly 500. The housing 100 has a containing space 101 and an opening 102 communicating with the containing space 101; the rotating member 200 is rotatably disposed in the containing space 101; a portion of the cable 300 can be coiled outside the rotating member 200 and can extend from the opening 102 to the outside of the housing 100; the first elastic member 400 is disposed between the rotating member 200 and the housing 100, and is used to provide a force for the rotating member 200 to rotate in the storage direction A; the limiting assembly 500 includes: a first limiting member 510, a second limiting member 520 and a third limiting member 530. The first stopper 510 is arranged at one end of the rotating member 200; the first stopper 510 has at least one first groove 511 on its circumferential side; the second stopper 520 is rotatably arranged on the housing 100; the second stopper 520 has a first protrusion 521 on its circumferential side for cooperating with the first groove 511; the end surface 529 of the second stopper also has a second protrusion 522 and a third protrusion 523 arranged at intervals; the second protrusion 522 and the third protrusion 523 have the same or close axial heights; the third stopper 530 is rotatably arranged on the housing 100 and is located between the second protrusion 522 and the third protrusion 523; the third stopper The peripheral side of 530 has at least one set of matching structures 531 for matching with the second protrusion 522 and the third protrusion 523; the second limit member 520 is used to push the third limit member 530 to rotate through the matching structure 531; the elastic component 600 is arranged between the second limit member 520 and the shell 100; in the stretched state, the elastic component 600 is used to provide a force for the second limit member 520 to rotate along the first direction B so that the first protrusion 521 is located in the first groove 511, and the matching structure 531 is used to match with the second protrusion 522 so that the second limit member 520 is in a positioning state where the first protrusion 521 is located in the first groove 511.

[0078] In the data cable storage device of the present application, since part of the cable 300 can be coiled outside the rotating member 200 and can extend from the opening 102 to the outside of the housing 100, when the cable 300 is pulled, the external force overcomes the deformation force of the first elastic member 400 and drives the rotating member 200 to rotate through the cable 300, and the length of the cable 300 extending outside the housing 100 increases. At this time, the first protrusion 521 is located outside the first groove 511, and the elastic component 600 is deformed; when the length of the cable 300 extending out of the housing 100 meets the requirement, the cable 300 is no longer pulled, and the first elastic member 400 can provide the rotating member 200 with a force to rotate in the storage direction A. After the rotating member 200 drives the cable 300 to rotate a short distance in the storage direction A, the deformation force of the elastic component 600 can provide a force for rotation along the first direction B to the second limiting member 520, so that the second limiting member 520 rotates until the first protrusion 521 is located in the first groove 511. At the same time, the matching structure 531 can also cooperate with the second protrusion 522 to make the second limiting member 520 in a positioning state where the first protrusion 521 is located in the first groove 511, so that the rotating member 200 can be prevented from driving the cable 300 to continue to rotate in the storage direction A through the first protrusion 521, so that the cable 300 can be stably in a suitable usage length. At the same time, in the related art, the two raised parts of the limiting structure in the data cable storage structure that cooperate with the gear have different heights, which makes the overall thickness of the limiting structure larger, causing the data cable storage structure to be set thicker; while in the ultra-thin data cable storage device of the present application, since the second raised part 522 and the third raised part 523 on the second limiting member 520 that cooperate with the third limiting member 530 are the same or close in axial height, at this time, the second limiting member 520 can be set thinner, so that the data cable storage device can also be set thinner, thereby realizing the lightness and thinness of the data cable storage device.

[0079] In the embodiment of the present application, the structure of the housing 100 is not limited. For example, the housing 100 may be a disc-shaped structure. For another example, the housing 100 may be a rectangular parallelepiped structure. As an example, Fig. 9 As shown, the housing 100 includes a first half shell 110 and a second half shell 120, which can be connected by a snap-fit ​​structure, a threaded structure, etc., and a receiving space 101 is defined between the first half shell 110 and the second half shell 120. Here, the housing 100 can have one opening 102 or two openings 102.

[0080] In the embodiment of the present application, the structure of the rotating member 200 is not limited. For example, the rotating member 200 can be a columnar structure. The implementation method of the rotating member 200 being rotatably disposed in the accommodating space 101 is not limited. For example, the rotating member 200 can be rotatably disposed in the accommodating space 101 through a rotating shaft structure. As an example, a first connecting column 140 is disposed in the accommodating space 101, and the rotating member 200 has a fourth connecting hole 230. The first connecting column 140 is passed through the fourth connecting hole 230 and can rotate in the fourth connecting hole 230; thereby, the rotating member 200 is rotatably disposed in the accommodating space 101 by passing the first connecting column 140 through the fourth connecting hole 230. Here, as Figure 8 As shown, the first connecting column 140 can be fixed to the second half shell 120. Of course, the first connecting column 140 and the second half shell 120 can also be a structural member; the first connecting column 140 can also be connected to the first half shell 110, for example, Figure 7 As shown, the first half shell 110 has a first connecting hole 133. Fig. 9 and Fig.10 As shown, the connecting member 810 passes through the first connecting hole 133 and is connected to the first connecting column 140. The connecting member 810 may be a screw, and a threaded hole may be provided on the first connecting column 140. In one application, the first connecting column 140 and the second half shell 120 are a structural member.

[0081] In the embodiment of the present application, the cable 300 can be stretched at one end to increase the length of the cable 300, or can be stretched at both ends to increase the length of the cable 300. As an example, Fig.10 As shown, the housing 100 has an opening 102. Figure 1 As shown, the first end of the cable 300 may be provided with a first interface 710, and the type of the first interface 710 may be a USB interface or a type-c interface. The first interface 710 is located outside the housing 100 for plugging with an interface of an external electronic device; the second end of the cable 300 is located in the accommodating space 101, and the second end of the cable 300 is electrically connected to a second interface 720 provided on the surface of the housing 100 through a connecting line 730; here, a circuit board may also be provided between the second interface 720 and the connecting line 730 to ensure that the second interface 720 and the cable 300 are always electrically connected during the rotation of the cable 300 relative to the housing 100. Of course, in other implementations, the housing 100 may also have two openings 102, and the two ends of the cable 300 may extend out of the housing 100 from the two openings 102, respectively, so as to adjust the length of the cable 300 by stretching the two ends of the cable 300.

[0082] In the embodiment of the present application, the structure of the first elastic member 400 is not limited, as long as the first elastic member 400 can provide a force for the rotating member 200 to rotate in the storage direction A. Fig.13 As shown, the first elastic member 400 may be a torsion spring. The first end of the first elastic member 400 is connected to the housing 100, and the second end of the first elastic member 400 is connected to the rotating member 200. When the cable 300 is stretched, the cable 300 drives the rotating member 200 to rotate, and the first elastic member 400 is deformed. The first elastic member 400 can provide a force for the rotating member 200 to rotate in the storage direction A through the restoring force of the deformation. As an example, Figure 8 As shown, the first connecting column 140 is provided with a first slot 141, and the first end of the first elastic member 400 is clamped in the first slot 141 to achieve the first end of the first elastic member 400 being fixed to the housing 100. As another example, Fig.14 As shown, the rotating member 200 has a winding portion 210 and a baffle portion 220 arranged adjacent to each other in the axial direction; the first elastic member 400 is arranged between the winding portion 210 and the housing 100. Fig.13 As shown, the winding portion 210 is an annular structure, a portion of the first elastic member 400 is wound in the cavity of the winding portion 210, a second slot 211 is provided on the wall of the winding portion 210, and the second end of the first elastic member 400 is clamped in the second slot 211, so that the second end of the first elastic member 400 is fixed to the winding portion 210 of the rotating member 200. Here, a portion of the cable 300 can be coiled outside the winding portion 210 and can extend from the opening 102 to the outside of the housing 100.

[0083] In the embodiment of the present application, the limiting assembly 500 includes a first limiting member 510, a second limiting member 520, a third limiting member 530 and an elastic member 600. The first limiting member 510, the second limiting member 520, the third limiting member 530 and the elastic member 600 cooperate to realize the positioning of the rotating member 200 relative to the housing 100, so that the cable 300 can be stably at a suitable length for use.

[0084] The structure of the first stopper 510 is not limited. For example, the first stopper 510 may be a plate-shaped structure. Figure 1 As shown, the first stopper 510 may be a disc-shaped structure. When the rotating member 200 includes a winding portion 210 and a baffle portion 220, the first stopper 510 may be disposed at an end of the baffle portion 220 facing away from the winding portion 210, so that the winding portion 210 and the first stopper 510 are separated by the baffle portion 220, that is, the cable 300 and the stopper assembly 500 are separated, so as to prevent the cable 300 and the stopper assembly 500 from affecting each other. Here, as Fig.14As shown, the first stopper 510 and the rotating member 200 can be different parts of the same structural member, so as to facilitate processing and manufacturing, and to improve the connection strength between the first stopper 510 and the baffle portion 220. Of course, the first stopper 510 and the rotating member 200 can also be different structural members, in which case, the first stopper 510 and the rotating member 200 can be connected by bonding, welding, threaded structure, etc.

[0085] The number of the first grooves 511 on the circumferential side of the first stopper 510 is not limited. Figures 1 to 4 As shown, four first grooves 511 are evenly arranged on the circumferential side of the first limiting member 510 along the circumferential direction.

[0086] The second stopper 520 can be rotatably disposed on the housing 100 via a rotating shaft structure. Figure 7 As shown, the first half shell 110 has a third connecting column 135, as shown in FIG. Fig.11 As shown, the second stopper 520 has a third connection hole 528, and the third connection column 135 is inserted in the third connection hole 528 and can rotate in the third connection hole 528, so that the second stopper 520 is rotatably arranged on the housing 100 by inserting the third connection column 135 in the third connection hole 528. Of course, in other implementations, the third connection column 135 can also be arranged on the second stopper 520, and the third connection hole 528 can also be arranged on the housing 100.

[0087] The second stopper 520 has a first protrusion 521 on its circumferential side for cooperating with the first groove 511; when the rotating member 200 rotates to a first groove 511 facing the second stopper 520, the second stopper 520 can rotate until the first protrusion 521 is located in the first groove 511, so that the second stopper 520 and the rotating member 200 are connected and matched, so that the second stopper 520 can prevent the rotating member 200 from rotating by the first protrusion 521 being located in the first groove 511, or the rotating member 200 can drive the second stopper 520 to rotate by the first protrusion 521 being located in the first groove 511. Of course, the second stopper 520 can also rotate until the first protrusion 521 is located outside the first groove 511, so that the second stopper 520 and the rotating member 200 are separated.

[0088] like Figure 1 and Figure 2As shown, the end face 529 of the second stopper also has a second protrusion 522 and a third protrusion 523 that are spaced apart; the second protrusion 522 and the third protrusion 523 have the same or similar axial heights. The end face 529 of the second stopper refers to a surface that is perpendicular to the axis of the second stopper 520. The cross-sectional shapes of the second protrusion 522 and the third protrusion 523 are not limited. For example, the cross-section of the second protrusion 522 may be an ellipse, and the cross-section of the third protrusion 523 may be similar to a triangle.

[0089] The third stopper 530 can be rotatably disposed on the housing 100 via a rotating shaft structure. Figure 7 As shown, the first half shell 110 has a second connecting column 134. Fig.12 As shown, the third stopper 530 has a second connection hole 532, and the second connection column 134 is inserted in the second connection hole 532 and can rotate in the second connection hole 532, so that the third stopper 530 is rotatably arranged on the housing 100 by inserting the second connection column 134 in the second connection hole 532. Of course, in other implementations, the second connection column 134 can also be arranged on the third stopper 530, and the second connection hole 532 can also be arranged on the housing 100.

[0090] The axis of the third stopper 530 and the axis of the second stopper 520 can be parallel, so that the second stopper 520 can push the third stopper 530 to rotate smoothly through the matching structure 531. Here, the end face of the third stopper 530 and the end face 529 of the second stopper can be arranged adjacent to each other. At this time, there is no other structural member between the end face of the third stopper 530 and the end face 529 of the second stopper, and the gap between the end face of the third stopper 530 and the end face 529 of the second stopper can be arranged smaller, so that the setting space of the stopper assembly 500 can be reduced. As an example, the third stopper 530 and the second protrusion 522 have the same or close axial heights, that is, the third stopper 530 can be arranged in the space defined by the second protrusion 522 and the third protrusion 523. At this time, there is no need to provide a separate setting space for the third stopper 530 in the housing 100, so that the data cable storage device can be made thinner. Here, the end surface of the third limiting member 530 refers to a surface of the third limiting member 530 that is perpendicular to the axis of the third limiting member 530 .

[0091] The third limiting member 530 is located between the second protrusion 522 and the third protrusion 523; the peripheral side of the third limiting member 530 has at least one group of matching structures 531 for matching with the second protrusion 522 and the third protrusion 523; the second limiting member 520 is used to push the third limiting member 530 to rotate through the matching structure 531, so that different areas of the matching structure 531 match with the second protrusion 522 and the third protrusion 523, so that the data cable storage device is in different states.

[0092] The form of the matching structure 531 is not limited, as long as the matching structure 531 can make the second stopper 520 be in a positioning state where the first protrusion 521 is located in the first groove 511 by matching with the second protrusion 522. As an example, the axial thickness of the third stopper 530 is uniformly set, and the matching structure 531 is arranged along the circumference of the third stopper 530. Since the matching structure 531 is arranged along the circumference of the third stopper 530, the axial thickness of the third stopper 530 can be set more uniformly, so that the third stopper 530 can be made thinner in the axial direction.

[0093] The number of the matching structures 531 is not limited. Fig.12 As shown, the third position-limiting member 530 has three groups of matching structures 531 , and the three groups of matching structures 531 are evenly distributed along the circumference of the third position-limiting member 530 .

[0094] In the embodiment of the present application, the structure of the elastic component 600 is not limited, as long as the elastic component 600 is used to provide a force for the second position-limiting member 520 to rotate along the first direction B in the stretched state, so that the first protrusion 521 is located in the first groove 511. For example, the elastic component 600 may include a spring, the first end of which may be fixed to the housing 100, and the second end of which may contact the second position-limiting member 520; in the stretched state, the spring is in a deformed state, and the spring is used to provide a force for the second position-limiting member 520 to rotate along the first direction B through the deformation force, so that the first protrusion 521 is located in the first groove 511.

[0095] In some optional implementations of the embodiments of the present application, the matching structure 531 includes: a first matching portion, a second matching portion and a third matching portion adjacently arranged along the circumference of the third limiting member 530; the first matching portion and the third matching portion are used to match with the second protrusion 522; the second matching portion is used to match with the third protrusion 523; wherein, the distance between the first matching portion and the axis is smaller than the distance between the third matching portion and the axis; in the stretched state, the second matching portion matches with the third protrusion 523; in the positioned state, the second protrusion 522 contacts with the third matching portion; in the storage state, the second protrusion 522 matches with the first matching portion, so that when the data cable storage device switches between two adjacent states, the second limiting member 520 can push the third limiting member 530 to rotate through the matching structure 531, so that when entering the next state, different positions of the second limiting member 520 and the third limiting member 530 match, thereby making the second limiting member 520 present a different state.

[0096] In this implementation, the specific structures of the first matching portion, the second matching portion and the third matching portion are not limited.

[0097] For example, Figures 1 to 4 As shown, the first matching portion includes a second groove 5311, the second matching portion includes a first side surface 5312, and the third matching portion includes a third groove 5313; the second groove 5311 and the third groove 5313 are used to match with the second protrusion 522; the first side surface 5312 is used to match with the second side surface of the third protrusion 523; wherein, the depth of the second groove 5311 is greater than the depth of the third groove 5313, that is, the distance between the second groove 5311 and the axis is smaller than the distance between the third groove 5313 and the axis; in the stretched state, the first side surface 5312 and the second side surface are adjacently arranged; in the positioned state, the second protrusion 522 is located in the third groove 5313; in the stored state, the second protrusion 522 is located in the second groove 5311.

[0098] During use, if Figure 4As shown, in the stretched state, the external force overcomes the deformation force of the first elastic member 400 to pull the cable 300, and the cable 300 drives the rotating member 200 to rotate along the stretching direction B, and the length of the cable 300 increases. At this time, the first protrusion 521 is located outside the first groove 511. When the cable 300 is pulled to a suitable length; the external force is removed, and the rotating member 200 rotates in the storage direction A under the deformation force of the first elastic member 400. When the rotating member 200 rotates to the side of the first groove 511 toward the second limiting member 520, the elastic component 600 provides a force for the second limiting member 520 to rotate along the first direction B, so that the first protrusion 521 is located in the first groove 511. At the same time, in the stretched state, since the first side surface 5312 and the second side surface are adjacently arranged, the second limiting member 520 also pushes the third limiting member 530 to rotate. When the second limiting member 520 rotates to the second protrusion 522 is located in the third groove 5313, as shown in FIG. Figure 2 As shown, the third limiting member 530 stops the second limiting member 520 from rotating, and because the first protrusion 521 is located in the first groove 511, at this time, the resistance of the first protrusion 521 to the rotating member 200 is greater than the force provided by the first elastic member 400 for the rotating member 200 to rotate in the storage direction A, so that the second limiting member 520 is in a positioning state where the first protrusion 521 is located in the first groove 511, so as to ensure that the cable 300 is stably at a suitable length; when the cable 300 needs to be stored in the housing 100, the cable 300 can be pulled again by external force, and the cable 300 drives the rotating member 200 to rotate along the stretching direction B, so that the first protrusion 521 is moved from the first limiting member 520 to the first groove 511. When the second stopper 520 is rotated until the second protrusion 522 is located in the second groove 5311, the first stopper 520 will push the third stopper 530 to rotate to the corresponding position of the second protrusion 522 and the second groove 5311. When the external force is removed, the first protrusion 521 will be located in the first groove 511 again, and the rotating member 200 will drive the second stopper to rotate a certain angle along the first direction B through the first protrusion 521. When the second stopper 520 is rotated until the second protrusion 522 is located in the second groove 5311, since the depth of the second groove 5311 is greater than the depth of the third groove 5313, the first protrusion 521 is located outside the first groove 511. Figure 3As shown, at this time, the second limit member 520 cannot prevent the rotating member 200 from rotating through the first protrusion 521, and the rotating member 200 continues to rotate along the storage direction A under the action of the first elastic member 400 until the part of the cable 300 that can be coiled outside the rotating member 200 is completely coiled outside the rotating member 200. When the length of the cable 300 needs to be adjusted, the cable 300 can be pulled by overcoming the deformation force of the first elastic member 400 through external force, and the cable 300 drives the rotating member 200 to rotate along the stretching direction B. When the rotating member 200 rotates until the first groove 511 faces the second limiting member 520, the first protrusion 521 enters the first groove 511, and the rotating member 200 can drive the second limiting member 520 to rotate along the second direction A through the first protrusion 521. At the same time, since the second protrusion 522 is located in the second groove 5311, the second limiting member 520 can push the third limiting member 530 to rotate a certain angle. When the rotating member 200 drives the second limiting member 520 to rotate along the second direction A through the first protrusion 521 until the first protrusion 521 is located outside the first groove 511, the data cable storage device is in a stretched state again. Figure 4 As shown, at this time, the first side surface 5312 and the second side surface are arranged adjacent to each other. The data cable storage device can repeat the above process during use, and repeatedly switch between the stretched state, the positioning state and the storage state in sequence to facilitate the use of the data cable storage device. Of course, in other forms of use, the data cable storage device can also be in the storage state for a short time. At this time, the user can adjust the length of the cable 300 by repeatedly switching the data cable storage device between the stretched state, the positioning state and the storage state. That is, the data cable storage device is in the storage state only to enter the stretched state and the positioning state again, not to store all the cables 300 in the housing 100.

[0099] The second direction A is opposite to the first direction B, the stretching direction B is opposite to the storage direction A, and the second direction A is the same as the storage direction A. For example, the stretching direction B is clockwise, the first direction B is clockwise, the storage direction A is counterclockwise, and the second direction A is counterclockwise.

[0100] During use, when the data cable storage device switches between adjacent states, the second limit member 520 can push the third limit member 530 to rotate a set angle through the matching structure 531, so that when entering the next state, the second limit member 520 matches the different positions of the third limit member 530, so that the first protrusion 521 of the second limit member 520 and the first groove 511 are in different relative position relationships.

[0101] In this example, if Figure 1 and Fig.12As shown, the circumferential side of the third stopper 530 also has a protruding structure located between the second groove 5311 and the third groove 5313, and the first side surface 5312 can be located on the side of the protruding structure facing the second groove 5311. Of course, the first side surface 5312 can be located on the side of the protruding structure facing the third groove 5313, as long as the first side surface 5312 and the second side surface are adjacently arranged in the stretched state.

[0102] In this example, if Figure 3 As shown, the shape of the insertion end of the second protrusion 522 matches the shape of the second groove 5311, and the end surface of the insertion end of the second protrusion 522 is used to contact the bottom surface of the second groove 5311, so that the insertion end of the second protrusion 522 can be completely inserted into the second groove 5311, so that the data cable storage device is stably in the storage state. Of course, in other implementations, the side surface of the insertion end of the second protrusion 522 can be used to contact the side surface of the second groove 5311.

[0103] like Figure 2 As shown, the end surface of the insertion end of the second protrusion 522 is used to contact the side surface of the third groove 5313, so that the data line storage device is stably in a positioning state. Of course, in other implementations, the end surface of the insertion end of the second protrusion 522 can be used to contact the bottom surface of the second groove 5311. As an example, Fig.11 As shown, the first angle C1 between the two side surfaces of the insertion end of the second protrusion 522 is less than 45 degrees. Fig.12 As shown, the second angle C2 between the two side surfaces of the third groove 5313 is greater than 90 degrees, so that the end surface of the insertion end of the second protrusion 522 can contact the side surface of the third groove 5313. Here, the value of the first angle C1 is not limited. For example, the range of the first angle C1 can be 39 degrees to 41 degrees; the value of the second angle C2 is not limited. For example, the range of the second angle C2 can be 100 degrees to 105 degrees. Fig.12 As shown, the third angle C3 between the two side surfaces of the second groove 5311 can range from 40 degrees to 42 degrees, so that the insertion end of the second protrusion 522 is inserted into the second groove 5311, and the end surface of the insertion end of the second protrusion 522 is used to contact the bottom surface of the second groove 5311.

[0104] Of course, in other examples, the first matching part, the second matching part and the third matching part can also be other structural forms. As an example, the first matching part, the second matching part and the third matching part can all be groove structures, or part of the first matching part, the second matching part and the third matching part is a groove structure, and the remaining part of the first matching part, the second matching part and the third matching part is a plane structure, as long as the second matching part is matched with the third protrusion 523 in the stretched state; the second protrusion 522 is in contact with the third matching part in the positioned state; and the second protrusion 522 is matched with the first matching part in the stored state, so that when the two states are switched, the second limiter 520 can push the third limiter 530 to rotate.

[0105] In some optional implementations of the embodiments of the present application, such as Fig.11 As shown, the second position-limiting member 520 may include: a first structure portion 526 and a second structure portion 527. The first structure portion 526 is rotatably connected to the housing 100; the elastic component 600 is disposed between the first structure portion 526 and the housing 100, so that the elastic component 600 provides a force for rotation along the first direction B to the second position-limiting member 520 through the first structure portion 526; the first end of the second structure portion 527 is connected to the first structure portion 526, and the second end of the second structure portion 527 has a first protrusion 521, and the second protrusion 522 and the third protrusion 523 are located on the end surface 5271 of the second structure portion.

[0106] In this implementation, the end surface 5271 of the second structure portion refers to a surface of the second structure portion 527 that is perpendicular to the axis of the second limiting member 520 .

[0107] In this implementation, the implementation of the rotatable connection between the first structure portion 526 and the housing 100 is similar to the implementation of the rotatable connection between the second stopper 520 and the housing 100, which will not be described in detail. Fig.11 As shown, the third connection hole 528 is disposed on the first structure portion 526. The implementation of the elastic component 600 disposed between the first structure portion 526 and the housing 100 is similar to the implementation of the elastic component 600 disposed between the second stopper 520 and the housing 100, which will not be repeated here.

[0108] In this implementation, the first part 5261 of the first structural part protrudes axially from the end face 5271 of the second structural part, and the third limiting member 530 is located in the space defined by the first part 5261, the second protrusion 522 and the third protrusion 523 of the first structural part; thereby, the axial setting space of the third limiting member 530 can be reduced; at the same time, since the first part 5261 of the first structural part protrudes axially from the end face 5271 of the second structural part, that is, the first part 5261, the second protrusion 522 and the third protrusion 523 of the first structural part are on the same side of the second limiting member 520, the axial size of the first structural part 526 can be increased to provide the matching strength between the first structural part 526 and the elastic component 600, and the overall axial size of the second limiting member 520 can be reduced.

[0109] In this implementation, the axial heights of the second protrusion 522 and the first part 5261 of the first structure part are the same or close, that is, the first part 5261 of the first structure part will not increase the overall axial size of the second limiter 520, so that the axial size of the second limiter 520 can be set as small as possible to achieve the lightweight and thinness of the data cable storage device.

[0110] In some optional implementations of the embodiments of the present application, the data cable storage device may also have a storage state; in the stretched state, the elastic component 600 provides a force for the second limit member 520 to rotate along the first direction B, and the first protrusion 521 is located outside the first groove 511; in the storage state, the elastic component 600 provides a force for the second limit member 520 to rotate along the second direction A, and the first protrusion 521 is located outside the first groove 511; in the positioning state, the elastic component 600 provides a force for the second limit member 520 to rotate along the second direction A, and the first protrusion 521 is located in the first groove 511; wherein the second direction A is opposite to the first direction B.

[0111] In this implementation, if Figure 2 As shown, in the positioning state, since the elastic component 600 provides the second limiting member 520 with a force for rotating along the second direction A, the second limiting member 520 can be prevented from rotating along the first direction B through the deformation force of the elastic component 600. At this time, the elastic component 600 and the matching structure 531 are both used to prevent the second limiting member 520 from rotating along the first direction B, so that the first protrusion 521 can be more stably located in the first groove 511 to prevent the rotating member 200 from rotating in the storage direction A. Of course, in other implementations, in the positioning state, the elastic component 600 may not provide the second limiting member 520 with a force for rotating along the second direction A. At this time, the matching structure 531 is used to prevent the second limiting member 520 from rotating along the first direction B.

[0112] In this implementation, if Figure 3As shown, in the stored state, the elastic component 600 provides a force for rotation along the second direction A to the second stopper 520, so that when switching from the stored state to the stretched state, the elastic component 600 provides a force for rotation along the second direction A to the second stopper 520, so that the first protrusion 521 can quickly enter the first groove 511. Of course, in other implementations, in the stored state, the elastic component 600 may not provide a force for rotation along the second direction A to the second stopper 520.

[0113] As an example, in the stretched state, the elastic component 600 provides a force for the second limit member 520 to rotate along the first direction B, and the first protrusion 521 is located outside the first groove 511; in the stored state, the elastic component 600 provides a force for the second limit member 520 to rotate along the second direction A, and the first protrusion 521 is located outside the first groove 511; in the positioned state, the elastic component 600 does not provide a force for the second limit member 520 to rotate along the second direction A, and the first protrusion 521 is located in the first groove 511.

[0114] In the present implementation, the structure of the elastic component 600 is not limited, as long as in the stretched state, the elastic component 600 is used to provide the second limit member 520 with a force for rotation along the first direction B, in the stored state, the elastic component 600 provides the second limit member 520 with a force for rotation along the second direction A, and in the positioned state, the elastic component 600 provides the second limit member 520 with a force for rotation along the second direction A.

[0115] For example, the elastic assembly 600 includes a third elastic member 620 and a second elastic member 610. The third elastic member 620 is used to provide a force for the second position-limiting member 520 to rotate along the first direction B; the second elastic member 610 is used to provide a force for the second position-limiting member 520 to rotate along the second direction A.

[0116] In this example, the structures of the third elastic member 620 and the second elastic member 610 are not limited. For example, the third elastic member 620 and the second elastic member 610 can both be spring-shaped structures, and the third elastic member 620 and the second elastic member 610 can be located on opposite sides of the second position-limiting member 520. For another example, the third elastic member 620 and the second elastic member 610 can both be torsion spring structures, and the third elastic member 620 and the second elastic member 610 can both be arranged on the shaft structure of the second position-limiting member 520 and the housing 100; as an example, the third elastic member 620 and the second elastic member 610 can be torsion spring structures sleeved on the third connecting column 135.

[0117] For another example, the second elastic member 610 and the third elastic member 620 are disposed on the housing 100 ; the second elastic member 610 and the third elastic member 620 are located on opposite sides of the second position-limiting member 520 , and are used to contact the second position-limiting member 520 respectively.

[0118] Here, the second elastic member 610 and the third elastic member 620 may both be strip-shaped structures. Of course, the second elastic member 610 and the third elastic member 620 may also be sheet-shaped structures.

[0119] Here, if Figure 1 As shown, the first end of the second elastic member 610 is connected to the shell 100, and the second end of the second elastic member 610 is used to contact the second limiting member 520; the first end of the third elastic member 620 is connected to the shell 100, and the second end of the third elastic member 620 is used to contact the second limiting member 520.

[0120] Here, if Figure 5 and Figure 6 As shown, the second limiting member 520 has a first recessed portion 524 and a second recessed portion 525 which are arranged opposite to each other on the circumferential side; the second end of the second elastic member 610 can be located in the first recessed portion 524, and the second end of the third elastic member 620 can be located in the second recessed portion 525, so as to ensure that the second end of the second elastic member 610 is always in contact with the second limiting member 520, and the second end of the third elastic member 620 is always in contact with the second limiting member 520, so as to prevent the second elastic member 610 and the third elastic member 620 from being separated from the second limiting member 520 respectively.

[0121] Here, if Figure 7 As shown, the second end of the second elastic member 610 includes a first contact arc surface 611, and a first contact plane 612 and a second contact plane 613 located on both sides of the first contact arc surface 611, so that the second end of the second elastic member 610 can rotate smoothly in the first recessed portion 524 to prevent the second end of the second elastic member 610 from getting stuck and damaged; the second end of the third elastic member 620 includes a second contact arc surface 621, and a third contact plane 622 and a fourth contact plane 623 located on both sides of the second contact arc surface 621, so that the second end of the third elastic member 620 can rotate smoothly in the second recessed portion 525 to prevent the second end of the third elastic member 620 from getting stuck and damaged.

[0122] In this example, if Figure 6 and Figure 7As shown, the shell 100 may include: a first wall body 130, a second limit member 520 and a third limit member 530 are arranged on the first wall body 130; the second elastic member 610 and the third elastic member 620 are respectively connected to the first wall body 130 on the side facing the accommodating space 101; on the projection plane parallel to the rotation axis, the projection surface area of ​​the second elastic member 610 and the third elastic member 620 is located outside the projection surface area of ​​the first wall body 130. By arranging the second elastic member 610 and the third elastic member 620 on the side of the first wall body 130 facing the accommodating space 101, it can be ensured that the first wall body 130 does not affect the deformation of the second elastic member 610 and the third elastic member 620, and the setting space of the second elastic member 610 and the third elastic member 620 can be reduced, thereby realizing the lightweight data cable storage device.

[0123] Here, the first wall body 130 may be located in the first half shell 110. At this time, the first half shell 110 includes the first wall body 130 and a side wall located at a peripheral side of the first wall body 130.

[0124] Here, if Fig.10 As shown, the first wall 130 may further include: a first slot 131 and a second slot 132. The first slot 131 is connected to the accommodating space 101 and corresponds to the position of the second elastic member 610; the second slot 132 is connected to the accommodating space 101 and corresponds to the position of the third elastic member 620; on the projection plane perpendicular to the rotation axis, the contour line of the first slot 131 is arranged adjacent to a part of the contour line of the second elastic member 610, and the contour line of the second slot 132 is arranged adjacent to a part of the contour line of the third elastic member 620; thus, the deformation space of the second elastic member 610 and the third elastic member 620 can be increased by the first slot 131 and the second slot 132, and the second elastic member 610 and the third elastic member 620 can cover the first slot 131 and the second slot 132, so that the data cable storage device is neater as a whole.

[0125] Here, the first wall 130, the second elastic member 610 and the third elastic member 620 can be different parts of the same structural member for easy processing and manufacturing; at the same time, forming the elastic component 600 through a partial structure on the housing 100 can greatly simplify the structure of the data line storage device. As an example, the first wall 130, the second elastic member 610 and the third elastic member 620 can be integrally formed by injection molding. Of course, the first wall 130, the second elastic member 610 and the third elastic member 620 can also be different structural members. In this case, the second elastic member 610 and the third elastic member 620 can be fixed to the first wall 130 by bonding, welding, threaded connection, etc.

[0126] It should be noted that when the elastic component 600 is used only in the stretched state to provide the second limiter 520 with a force for rotation along the first direction B, the elastic component 600 may only include the third elastic component 620. When in the stretched state, the elastic component 600 provides the second limiter 520 with a force for rotation along the first direction B; in the stored state, the elastic component 600 provides the second limiter 520 with a force for rotation along the second direction A; in the positioned state, when the elastic component 600 does not provide the second limiter 520 with a force for rotation along the second direction A, the elastic component 600 may include the third elastic component 620 and the second elastic component 610, and the second elastic component 610 may be set shorter. In the positioned state, the second elastic component 610 contacts the second limiter 520, but the second elastic component 610 does not deform and does not provide deformation force. In the stored state, the second elastic component 610 deforms and can provide deformation force.

[0127] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
