DETAILED DESCRIPTION

[0096] The technical solution of the present application is further elaborated in detail below with reference to the accompanying drawings and specific embodiments.

[0097] In the description of the embodiments of this 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 it can be the internal 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 meaning of the above terms can be understood according to the specific circumstances.

[0098] It should be noted that the terms "first, second, and third" in the embodiments of the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understood that the terms "first, second, and third" can be interchanged to represent a specific order or precedence where permitted. It should be understood that the objects distinguished by "first, second, and third" can be interchanged where appropriate, such that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0099] The cable storage device 100 , the data cable device, and the ultra-thin retractable data cable device according to the embodiments of the present application are described in detail below with reference to FIG. 1 to FIG. 17 .

[0100] The cable storage device 100 includes a rotating member 110 and a cable 130 . The cable 130 includes a fixed section 131 and a winding section 132 . The fixed section 131 is fixed to the rotating member 110 , and the winding section 132 can be coiled outside the fixed section 131 .

[0101] In the related art, cables generally do not have a storage structure and are placed directly on the desktop or in a backpack. The cables often become entangled with other items on the desktop or in the backpack. When using the cables, the cables need to be removed from the entangled items first, which increases the time users spend using the cables and provides a poor user experience. In contrast, in the cable storage device 100 of the present application, the cable 130 includes a fixed section 131 and a winding section 132; the fixed section 131 is fixed to the rotating member 110, and the winding section 132 can be coiled outside the fixed section 131. In this case, the cable 130 will not become entangled with other items, saving the time of removing the cable 130 from the entangled items, which can greatly improve the user experience of the cable 130.

[0102] In the embodiment of the present application, the manner in which the fixing section 131 is fixed to the rotating member 110 is not limited. For example, the fixing section 131 can be fixed to the rotating member 110 by a snap-fit ​​structure or adhesive.

[0103] For another example, the rotating member 110 includes a first seat portion 111 and a first connecting portion 112; the first seat portion 111 has a storage space 1113; the first connecting portion 112 is arranged in the storage space 1113 along the axial direction of the rotating member 110; the cable storage device 100 also includes: a first strip member 120, the first strip member 120 is arranged in the storage space 1113 along the axial direction of the rotating member 110; a first gap is defined between the first strip member 120 and the first connecting portion 112; the cable 130 includes a fixed section 131; the first part 1311 of the fixed section 131 is clamped in the first gap, and the second part 1312 of the fixed section 131 is wrapped around the circumference of the first strip member 120.

[0104] In some examples, the cable storage device includes a rotating member and a cable. The rotating member is generally provided with a fixed space and a winding space located outside the fixed space; a part of the cable is fixed in the fixed space, and the other part of the cable is wound in the winding space; since a special fixed space for the cable needs to be set up, the volume of the rotating member is large, and the setting space of the rotating member is large; and when a first gap is defined between the first strip 120 and the first connecting portion 112, the first part 1311 of the fixed section 131 is clamped in the first gap, and the second part 1312 of the fixed section 131 is wound around the circumference of the first strip 120, and the fixed section 131 of the cable 130 can be fixed by the first strip 120 and the first connecting portion 112. The rotating member 110 does not need to set up a separate fixed space for fixing the fixed section 131, which can reduce the setting space of the rotating member 110 and realize the miniaturization of the cable storage device 100.

[0105] As shown in Figures 1 and 8, an embodiment of the present application also describes a data cable device, which includes a shell 200 and a cable storage device 100 of an embodiment of the present application; the shell 200 has a accommodating cavity 210, and a second connecting portion 220 located in the accommodating cavity 210; the rotating member 110 is arranged in the accommodating cavity 210; the second connecting portion 220 is rotatably connected to the first connecting portion 112; so that the rotating member 110 can rotate in the accommodating cavity 210 by being rotatably connected to the first connecting portion 112 through the second connecting portion 220.

[0106] The housing 200 may further include two openings 230, each of which is in communication with the accommodating cavity 210, so that the free ends of the cable 130 can pass through the two openings 230 and be located outside the housing 200. The two openings 230 may be provided along a circumferential gap of the housing 200. As an example, the two openings 230 may be located on opposite sides of the housing 200.

[0107] The structure of the housing 200 is not limited. For example, as shown in FIG3 , the housing 200 may include a top housing 201 and a bottom housing 202 ; a receiving cavity 210 and two openings 230 are defined between the top housing 201 and the bottom housing 202 ; a second connecting portion 220 is connected to the top housing 201 ; the second connecting portion 220 and the bottom housing 202 may also be connected by screws; and the housing 200 may further include a cover 203 , which is disposed on a side of the bottom housing 202 facing away from the top housing 201 to shield the connection area between the bottom housing 202 and the top housing 201 , thereby making the overall appearance of the data cable device more neat.

[0108] The implementation method of rotatably connecting the second connecting portion 220 to the first connecting portion 112 is not limited.

[0109] For example, in some embodiments, as shown in Figure 1, the first connecting portion 112 has a through hole 1121 arranged along the axial direction of the rotating member 110, the second connecting portion 220 is inserted into the through hole 1121, and the second connecting portion 220 can rotate in the through hole 1121, thereby enabling the rotating member 110 to rotate in the accommodating cavity 210.

[0110] For example, in other embodiments, the first connecting portion 112 has a first boss arranged axially along the rotating member 110, and the second connecting portion 220 includes a groove, the first boss is inserted into the groove, and the first boss can rotate in the groove, thereby enabling the rotating member 110 to rotate in the accommodating cavity 210.

[0111] In the embodiment of the present application, the structure of the first seat portion 111 of the rotating member 110 is not limited.

[0112] For example, in some embodiments, as shown in Figure 2, the first seat 111 has a first plate portion 1111 and a second plate portion 1112 spaced apart in the axial direction of the rotating member 110; a storage space 1113 is defined between the first plate portion 1111 and the second plate portion 1112; the first connecting portion 112 is respectively connected to the first plate portion 1111 and the second plate portion 1112; the first strip 120 is respectively connected to the first plate portion 1111 and the second plate portion 1112; so that the cable 130 can be stored between the first plate portion 1111 and the second plate portion 1112, which can prevent the cable 130 from being worn; and the plate-like structure can also reduce the weight of the first seat 111, thereby realizing the lightweight and thinning of the rotating member 110.

[0113] Here, the first plate portion 1111, the second plate portion 1112, and the first connecting portion 112 can be different parts of the same structural member. Of course, the first plate portion 1111, the second plate portion 1112, and the first connecting portion 112 can also be different structural members. In this case, the first plate portion 1111, the second plate portion 1112, and the first connecting portion 112 can be connected by welding or bonding.

[0114] Here, the first strip-shaped member 120 may be connected to the first plate portion 1111 and the second plate portion 1112 respectively by tight fit, welding, or bonding.

[0115] Here, the shape of the first plate portion 1111 is not limited. For example, the first plate portion 1111 may be a disc-shaped structure. In this case, the axis of the first plate portion 1111 may be the rotation axis of the rotating member 110.

[0116] Here, the shape of the second plate portion 1112 is not limited. For example, the second plate portion 1112 may be a disc-shaped structure. In this case, the axis of the second plate portion 1112 may be the rotation axis of the rotating member 110.

[0117] The second plate portion 1112 and the first plate portion 1111 may both be disc-shaped structures, and the diameter of the second plate portion 1112 may be the same or substantially the same as the diameter of the first plate portion 1111. Of course, the diameter of the second plate portion 1112 may also be different from the diameter of the first plate portion 1111.

[0118] Of course, in other embodiments, the first seat portion 111 may also only include the first plate portion 1111 or the second plate portion 1112. In this case, one side of the first plate portion 1111 or the second plate portion 1112 is the storage space 1113; the first connecting portion 112 and the first strip-shaped member 120 can be arranged on one side of the first plate portion 1111 or the second plate portion 1112.

[0119] The first connection portion 112 is used to connect to the second connection portion 220 of the housing 200 to enable the rotating member 110 to rotate relative to the housing 200 .

[0120] The structure of the first connecting portion 112 is not limited. For example, in some implementations, the first connecting portion 112 can be a strip-shaped structure. The cross-sectional shape of the first connecting portion 112 is not limited. For example, the cross-section of the first connecting portion 112 can be circular, in which case the first connecting portion 112 can be a columnar structure. For another example, the first connecting portion 112 can have a first width direction that is relatively larger in the radial direction and a second width direction that is relatively smaller in the radial direction. In other words, the cross-section of the first connecting portion 112 is non-circular. As one example, the cross-section of the first connecting portion 112 is rectangular. As another example, the cross-section of the first connecting portion 112 is elliptical. In this case, the surface of the first connecting portion 112 is a curved surface, which can prevent the first connecting portion 112 from abrading the cable 130. As another example, the first connecting portion 112 can have two opposing flat surfaces and two convex curved surfaces on its circumference. The two flat surfaces are connected to the two convex curved surfaces, respectively, to ensure a smooth transition between the circumferential surfaces of the first connecting portion 112 and prevent the first connecting portion 112 from abrading the cable 130.

[0121] In the embodiment of the present application, the first strip member 120 is arranged in the receiving space 1113 along the axial direction of the rotating member 110; a first gap is defined between the first strip member 120 and the first connecting portion 112 so that the fixing section 131 of the cable 130 can be fixed through the first gap.

[0122] The shape of the first strip 120 is not limited. For example, the surface of the first strip 120 around which the fixed section 131 is wound is an arcuate surface. In some examples, the cable storage device includes a rotating member and a cable. The rotating member is generally provided with a fixed space and a winding space located outside the fixed space. The fixed space and the winding space are connected by a cable retaining groove. A portion of the cable is fixed in the fixed space through the cable retaining groove, and another portion of the cable is wound in the winding space. The cable is easily scratched and damaged by the corners of the side walls of the cable retaining groove. A first gap is defined between the first strip 120 and the first connecting portion 112. The first portion 1311 of the fixed section 131 is retained in the first gap, and the second portion 1312 of the fixed section 131 is wound around the side of the first strip 120. The surface of the first strip 120 around which the fixed section 131 is wound is an arcuate surface, thereby preventing the first strip 120 from scratching the cable 130 and ensuring the service life of the cable 130.

[0123] As an example, the first strip member 120 can be a columnar structure. The columnar first strip member 120 can prevent the first strip member 120 from scratching the cable 130 and can also reduce the setting space of the first strip member 120, thereby reducing the volume of the rotating member 110 and realizing the miniaturization of the cable storage device 100.

[0124] As shown in Figure 1, in some optional implementations of the application embodiment, the cable storage device 100 may further include: a second strip member 140, the second strip member 140 is arranged in the storage space 1113 along the axial direction of the rotating member 110; a second gap is defined between the second strip member 140 and the first connecting portion 112; the fixed section 131 may further include: a third part 1313, the third part 1313 is located at the end of the first part 1311 facing away from the second part 1312; the third part 1313 is clamped in the second gap, and the parts of the fixed section 131 located at both ends of the third part 1313 are arranged around the circumference of the first connecting portion 112. At this time, both parts of the fixed section 131 are clamped in the gap, and the second strip member 140 can make the fixed section 131 more firmly fixed to prevent the fixed section 131 from moving relative to the rotating member 110.

[0125] In this embodiment, the shape of the second strip 140 is not limited. For example, the surface of the second strip 140 facing the first connecting portion 112 is a curved surface, so that the second strip 140 can clamp the third portion 1313 of the fixing section 131 through the curved surface, thereby preventing the second strip 140 from scratching the cable 130 and ensuring the service life of the cable 130.

[0126] As an example, the second strip member 140 can be a columnar structure. The columnar second strip member 140 can prevent the second strip member 140 from scratching the cable 130 and reduce the installation space of the second strip member 140, thereby reducing the volume of the rotating member 110 and realizing the miniaturization of the cable storage device 100.

[0127] In this embodiment, the second strip 140 and the first strip 120 may be spaced apart along the circumference of the first connecting portion 112. For example, as shown in FIG1 , the second strip 140 and the first strip 120 are located on opposite sides of the first connecting portion 112, so that the fixing section 131 of the cable 130 is fixed by the opposite side of the first connecting portion 112, thereby making the fixing section 131 of the cable 130 more firmly fixed.

[0128] As an example, as shown in Figure 1, the first connecting part 112 has a first width direction with a relatively larger size and a second width direction with a relatively smaller size in the radial direction; the first strip member 120 and the second strip member 140 are located on the opposite sides of the first connecting part 112 in the second width direction, and the first connecting part 112, the first strip member 120 and the second strip member 140 form a winding structure. The winding segment 132 of the cable 130 is arranged along the circumference of the winding structure formed by the first connecting part 112, the first strip member 120 and the second strip member 140, which can make the sizes of the winding segment 132 in the first width direction and the second width direction after winding closer, and make the shape of the winding segment 132 after winding closer to the disc shape, so that the shape of the winding segment 132 is closer to the disc-shaped rotating part 110.

[0129] In an embodiment of the present application, as shown in Figures 1 and 8, the cable 130 may further include a winding section 132; the winding section 132 is located at both ends of the fixed section 131 and can be arranged outside the fixed section 131 along the circumferential disk of the fixed section 131, so that the two winding sections 132 are stored in the storage space 1113; the two winding sections 132 can also extend out of the shell 200 through the two openings 230 of the shell 200, so as to increase the effective use length of the data cable device.

[0130] The cable 130 may also include two interface portions 133, which are respectively connected to one end of the two winding segments 132 away from the fixed segment 131. At least part of the two interface portions 133 is located outside the shell 200, so that when the data line device is needed, the two interface portions 133 are respectively plugged into the interfaces of two different devices, so that the two different devices can transmit signals, charge, etc. through the data line device.

[0131] Here, the two interface portions 133 may be provided with only one plug interface, or may be provided with multiple plug interfaces, and the types of the multiple plug interfaces may be different, so that the data cable device can be electrically connected to external devices with different similar interfaces. As an example, as shown in FIG8 , one of the two interface portions 133 includes one plug interface, and the other of the two interface portions 133 includes three plug interfaces of different types.

[0132] When the operator pulls the two ends of the cable 130 outside the housing 200 or one end of the cable 130, the rotating member 110 rotates relative to the housing 200, and the two winding sections 132 inside the housing 200 extend out of the housing 200 from the two openings 230, and the distance between the two interface portions 133 increases. When the two ends of the cable 130 outside the housing 200 or one end of the cable 130 is continued to be pulled, the distance between the two interface portions 133 is further increased, so that the data cable device can adaptively adjust the distance between the two interface portions 133 to adapt to the two interface portions 133. 33 corresponds to the distance between the two connected devices; when the distance between the two interface parts 133 makes the two interface parts 133 correspond to the interfaces of the two devices and can be plugged into them, the operator can stop pulling the two ends of the cable 130 or one end of the cable 130 outside the shell 200; at this time, if the operator stops pulling the two ends of the cable 130 or one end of the cable 130 outside the shell 200, the rotating part 110 can stop rotating directly relative to the shell 200 or the rotating part 110 can stop rotating relative to the shell 200 based on the positioning component 400 of the data cable device.

[0133] For example, in some embodiments, the cable storage device 100 may further include: an operating member, the operating member is connected to the rotating member 110, and a portion of the operating member protrudes outside the shell 200 through the opening of the shell 200. When the operator pulls the two ends of the cable 130 located outside the shell 200 or one end of the cable 130, the rotating member 110 drives the operating member to rotate in the opening; when the operator stops pulling the two ends of the cable 130 located outside the shell 200 or one end of the cable 130, the rotating member 110 directly stops rotating based on the friction between the shell 200; when it is necessary to store the winding segment 132 located outside the shell 200 in the storage space 1113 of the rotating member 110, the operating member can be manually rotated so that the operating member drives the rotating member 110 to rotate in the opposite direction, and the winding segment 132 located outside the shell 200 enters the shell 200 from the opening 230 and is stored in the storage space 1113, and the distance between the two interface parts 133 is reduced.

[0134] For another example, in some other embodiments, the first seat portion 111 has a first plate portion 1111 and a second plate portion 1112 spaced apart in the axial direction of the rotating member 110, as shown in FIG4 , the data line device may further include: a first elastic member 310, the first elastic member 310 is arranged on a side of the first plate portion 1111 away from the second plate portion 1112, the first end of the first elastic member 310 is fixed to the housing 200, and the second end of the first elastic member 310 is fixed to the first plate portion 1111 to provide a rotational restoring force to the rotating member 110; that is, when the operator pulls the two ends of the cable 130 located outside the housing 200 or one end of the cable 130, the first elastic member 310 is deformed; when the operator stops pulling the cable 130 located outside the housing 200, the first elastic member 310 is deformed. 00, the rotating member 110 stops rotating based on the positioning function of the positioning component 400 of the data cable device; when it is necessary to store the winding segment 132 located outside the shell 200 in the storage space 1113 of the rotating member 110, the operator can gently pull the two ends of the cable 130 located outside the shell 200 or one end of the cable 130 to separate the rotating member 110 from the positioning function of the positioning component 400 of the data cable device, and rotate in the opposite direction based on the deformation of the first elastic member 310, and the winding segment 132 located outside the shell 200 enters the shell 200 from the opening 230 and is stored in the storage space 1113, and the distance between the two interface parts 133 is reduced.

[0135] Here, the first elastic member 310 may be a coil spring. The first end of the first elastic member 310 may be fixed to the second connecting portion 220. The first plate portion 1111 may have a fixing wall 1114 on a side facing away from the second plate portion 1112, and the second end of the first elastic member 310 may be secured to the fixing wall 1114, as shown in FIG4 .

[0136] Of course, the data cable device can also stop the rotation of the rotating member 110 relative to the housing 200 by other means. For example, an external clamping structure can be clamped on the portion of the winding segment 132 located at the opening 230, so that the clamping structure is locked at the opening 230, thereby preventing the winding segment 132 from entering the housing 200 through the opening 230, and stopping the rotation of the rotating member 110 relative to the housing 200; when it is necessary to store the winding segment 132 located outside the housing 200 in the storage space 1113, the external clamping structure can be removed from the winding segment 132. At this time, the rotating member 110 rotates in the opposite direction based on the deformation of the first elastic member 310, and the winding segment 132 located outside the housing 200 enters the housing 200 from the opening 230 and is stored in the storage space 1113, thereby reducing the distance between the two interface portions 133. As an example, the clamping structure can be a clip.

[0137] Here, the structure of the positioning assembly 400 is not limited.

[0138] For example, as shown in Figures 5, 6, and 7, the positioning assembly 400 may include a moving gear 410, a connecting member 420, a limiting gear 430, and a reset member 440. The moving gear 410 is fixed to the side of the second plate portion 1112 facing away from the first plate portion 1111. The connecting member 420 and the limiting gear 430 are rotatably mounted on the bottom shell 202 of the housing 200. One end of the reset member 440 abuts against the connecting member 420, while the other end of the reset member 440 is fixed to the bottom shell 202 of the housing 200. When the cable storage device 100 rotates, the cable storage device 100 drives the moving gear 410 to rotate. The moving gear 410 is provided with a first groove 411. The number of first grooves 411 can be one or more, and the number of first grooves 411 affects the length of the data cable during each positioning operation. The connecting member 420 is provided with a first protrusion 421, which mates with the first groove 411. The connecting member 420 is further provided with a second protrusion 422 and a third protrusion 423 that protrude axially. A limiting gear 430 is rotatably connected to the housing 200 and is located between the first protrusion 421 and the second protrusion 422. The connecting member 420 can swing along with the moving gear 410, so that the first protrusion 421 and the second protrusion 422 respectively engage with different limiting grooves 431 in the limiting gear 430, thereby achieving engagement and disengagement between the first protrusion 421 and the first groove 411. A reset member 440 has one end abutting against the connecting member 420, and the other end connected to the bottom shell 202 of the housing 200, so as to store energy when the moving gear 410 rotates in a first direction and release energy when the moving gear 410 moves in a direction opposite to the first direction. The reset member 440 is disposed on one side of the connecting member 420 and engages with the moving gear 410, elastically deforming as the moving gear 410 moves. The rotation of the rotating member 110 can drive the motion gear 410 to move and then drive the reset member 440 to produce elastic deformation, so as to provide the rotating member 110 with a pre-tightening force to swing toward or away from one side of the reset member 440. By rotating the rotating member 110, the cable 130 wound on the rotating member 110 can be freely stretched or contracted. By cooperating with the rotating member 110 and the motion gear 410, the rotating member 110 can position the cable 130 when the cable 130 wound on the rotating member 110 is pulled out to any length. When the user pulls out the appropriate length, the cable 130 can be directly released. The rotating member 110 cooperates with the motion gear 410, the connecting member 420 and the reset member 440 to keep the cable 130 at this length for easy use. It can be seen that the design of the positioning assembly 400 cooperating with the rotating member 110 simplifies the retractable structure of the data cable and effectively improves the practicality of the data cable.

[0139] As shown in Figures 5 and 6, the moving gear 410 includes at least two first grooves 411, and the first protrusion 421 is a protrusion that cooperates with the first grooves 411. Through the cooperation of the first grooves 411 and the first protrusion 421, on the one hand, the moving gear 410 can drive the connecting member 420 to swing. On the other hand, when the connecting member 420 moves a certain distance, it can slide out of the first groove 411 and rebound due to the preload force, so that it can cooperate with the next first groove 411. At least two first grooves 411 ensure that when the moving gear 410 rotates, the connecting member 420 will not remain in a state of not cooperating with the first groove 411 for a long time, thereby avoiding the situation where the cable 130 cannot be locked in time. It can be seen that the design of the first protrusion 421 cooperating with the first groove 411 makes the data cable structure more reasonable and smoother to use.

[0140] The limiting gear 430 is provided with limiting grooves 431 of different depths at intervals. The second protrusion 422 and the third protrusion 423 are respectively provided at both ends of the connecting member 420 to cooperate with the connecting member 420 .

[0141] As shown in Figures 5 and 7, when the cable 130 is stretched, the moving gear 410 drives the connecting member 420 to swing through the second protrusion 422, so that the second protrusion 422 contacts the limit gear 430 and pushes the limit gear 430 to rotate. When the stretching stops, the rotating member 110 is rotated a short distance due to the elastic force of the reset member 440. At this time, the rotation of the rotating member 110 and the pre-tightening force provided by the reset member 440 drive the connecting member 420 to swing back a distance. At this time, the second protrusion 422 of the connecting member 420 is in contact with the limit gear 430. Cooperating with the limiting groove 431 of the limiting gear 430, the connecting member 420 is fixed to the current position, so that the moving gear 410 cooperating with the first protrusion 421 is fixed to the current position, thereby realizing the fixation of the rotating member 110 and the cable 130; when it is necessary to recycle the cable 130, the cable 130 is stretched a suitable distance, and the moving gear 410 drives the connecting member 420 to swing a certain distance, so that the third protrusion 423 pushes the limiting gear 430 to rotate, and the limiting groove 431 is rotated to the predetermined position. When releasing the hand, due to the rotation of the moving gear 410 and the existence of the pre-tightening force, the connecting member 420 swings back, and the third protrusion 423 cooperates with the limiting groove 431. At this time, the first protrusion 421 no longer cooperates with the first groove 411 of the moving gear 410, and the moving gear 410 drives the rotating member 110 to rotate, completing the recovery of the cable 130.

[0142] The ultra-thin retractable data cable device according to the embodiment of the present application is described in detail below with reference to FIG. 9 to FIG. 17 .

[0143] The ultra-thin retractable data cable device comprises a housing 200 and a cable storage device according to an embodiment of the present invention. The housing 200 has a receiving chamber 210; a rotating member 110 is rotatably disposed within the receiving chamber 210; and the cable 130 comprises a fixed section 131 and a winding section 132. The fixed section 131 is fixed to the rotating member 110, and the winding section 132 is capable of being coiled around the circumference of the rotating member 110. The coiled winding section 132 is located within the space defined by the housing 200.

[0144] In some examples, the data cable device includes a shell, a rotating part and a cable. The rotating part is generally provided with a storage groove for storing the cable. For example, two oppositely arranged walls are provided at the axial ends of the rotating part, and a storage groove is formed between the two oppositely arranged walls, so that the rotating part has a larger axial thickness. At this time, the shell that accommodates the rotating part needs to be set thicker, resulting in the data cable device being thicker as a whole; while in the ultra-thin telescopic data cable device, the cable 130 includes a fixed section 131 and a winding section 132; the fixed section 131 is fixed to the rotating part 110, and the winding section 132 can be coiled around the circumference of the rotating part 110, and the coiled winding section 132 is located in the space defined by the shell 200, that is, there is no need to set a storage groove on the rotating part 110, the axial thickness of the rotating part 110 is smaller, and the thickness of the shell 200 can be set smaller, thereby realizing the lightweight and thinness of the ultra-thin telescopic data cable device.

[0145] In the embodiment of the present application, the thickness direction of the ultra-thin retractable data cable device may be the same as or substantially the same as the axial direction of the rotating member 110 .

[0146] In the embodiment of the present application, the structure of the housing 200 is not limited. For example, the housing 200 may be a disc-shaped structure.

[0147] As shown in Figure 9, the shell 200 can have a first wall 204 and a second wall 205 that are relatively arranged in the thickness direction of the ultra-thin telescopic data line device; the coiled winding segment 132 is located in the space defined by the first wall 204 and the second wall 205, that is, the coiled winding segment 132 is limited by the first wall 204 and the second wall 205 of the shell 200, and the rotating part 110 does not need to be provided with a limiting wall in the axial direction, so that the axial thickness of the rotating part 110 is smaller, and the thickness of the shell 200 can be set smaller, thereby realizing the lightweight and thinness of the ultra-thin telescopic data line device.

[0148] In the thickness direction of the ultra-thin telescopic data cable device, there is a gap between the cable 130 and the first wall 204 of the shell 200 and the second wall 205 of the shell 200, and the minimum thickness of the ultra-thin telescopic data cable device is equal to the sum of the width of the cable 130, the thickness of the first wall 204, the thickness of the second wall 205 and the gap; thereby, the ultra-thin telescopic data cable device can be made thin and lightweight.

[0149] The gaps between the cable 130 and the first wall 204 and the second wall 205 of the housing 200 can be a first gap between the cable 130 and the first wall 204 of the housing 200, and a second gap between the cable 130 and the second wall 205 of the housing 200, so that the cable 130 can freely expand and contract within the accommodating cavity 210 without being abraded by the first wall 204 and the second wall 205. The minimum thickness of the ultra-thin retractable data cable device is equal to the sum of the width of the cable 130, the thickness of the first wall 204, the thickness of the second wall 205, the first gap, and the second gap.

[0150] A gap may exist between the cable 130 and the first wall 204 and the second wall 205 of the housing 200. Alternatively, a first gap may exist between the cable 130 and the first wall 204 of the housing 200, and no gap exists between the cable 130 and the second wall 205 of the housing 200. This allows the cable 130 to freely expand and contract within the accommodating cavity 210 without being abraded by the first wall 204. The minimum thickness of the ultra-thin retractable data cable device is equal to the sum of the width of the cable 130, the thickness of the first wall 204, the thickness of the second wall 205, and the first gap.

[0151] A gap may exist between the cable 130 and the first wall 204 and the second wall 205 of the housing 200. Alternatively, a second gap may exist between the cable 130 and the second wall 205 of the housing 200, while no gap exists between the cable 130 and the first wall 204 of the housing 200. This allows the cable 130 to freely expand and contract within the accommodating cavity 210 without being abraded by the second wall 205. The minimum thickness of the ultra-thin retractable data cable device is equal to the sum of the width of the cable 130, the thickness of the first wall 204, the thickness of the second wall 205, and the second gap.

[0152] Here, there are no other structural parts between the first wall 204 and the coiled winding segment 132, and there are no other structural parts between the second wall 205 and the coiled winding segment 132, so that the coiled winding segment 132 can be directly limited in the thickness direction of the ultra-thin telescopic data line device by the first wall 204 and the second wall 205 to prevent the coiled winding segment 132 from moving in the thickness direction of the ultra-thin telescopic data line device.

[0153] The structure of the first wall 204 is not limited. For example, in some embodiments, the first wall 204 can be a flat plate structure. For another example, in other embodiments, the first wall 204 can be a curved plate structure.

[0154] The structure of the second wall 205 is not limited. For example, in some embodiments, the second wall 205 can be a flat plate structure. For another example, in other embodiments, the second wall 205 can be a curved plate structure.

[0155] As shown in Figure 9, the shell 200 also has a first opening 161 and a second opening 162 that are connected to the accommodating cavity 210; the number of winding segments 132 can be two, and the two winding segments 132 are located at both ends of the fixed segment 131; the cable 130 may also include: a first interface portion 320 and a second interface portion 330, the first interface portion 320 is connected to one of the two winding segments 132; at least a portion of the first interface portion 320 passes through the first opening 161 and is located outside the shell 200; the second interface portion 330 is connected to the other of the two winding segments 132; at least a portion of the second interface portion 330 passes through the second opening 162 and is located outside the shell 200; so that the ultra-thin retractable data line device is plugged into the interface of the external first device through the first interface portion 320, and is plugged into the interface of the external second device through the second interface portion 330, so that the first device and the second device can be electrically connected through the ultra-thin retractable data line device to achieve charging, signal transmission, etc.

[0156] The number of interfaces of the first interface portion 320 is not limited. For example, in some embodiments, the first interface portion 320 may include at least two first interfaces, and the types of the at least two first interfaces may be the same or different. As an example, the at least two first interfaces may include at least two of: a USB interface, a Type-C interface, a micro interface, and a Lightning interface.

[0157] The number of interfaces of the second interface portion 330 is not limited. For example, in some embodiments, the second interface portion 330 may include at least two second interfaces, and the types of the at least two second interfaces may be the same or different. As an example, the at least two second interfaces may include at least two of: a USB interface, a Type-C interface, a micro interface, and a Lightning interface.

[0158] The interface type of the first interface portion 320 may be the same as or different from the interface type of the second interface portion 330. As an example, as shown in FIG9 , the first interface portion 320 includes a Type-C interface, and the second interface portion 330 includes a Type-C interface.

[0159] The first opening 161 and the second opening 162 may be spaced apart along the circumference of the housing 200. As an example, as shown in FIG9 , the first opening 161 and the second opening 162 are located on opposite sides of the housing 200.

[0160] The shell 200 may include a top shell 201 and a bottom shell 202. The top shell 201 and the bottom shell 202 can be fixedly connected by screws, snap-fit ​​structures, etc., and a accommodating cavity 210 and a first opening 161 and a second opening 162 connected to the accommodating cavity 210 are defined between the top shell 201 and the bottom shell 202.

[0161] The top case 201 may include a first wall 204 and sidewalls surrounding the first wall 204. The bottom case 202 may include a second wall 205 and sidewalls surrounding the second wall 205. The sidewalls surrounding the first wall 204 and the sidewalls surrounding the second wall 205 define a first opening 161 and a second opening 162.

[0162] The top shell 201 may include a third connecting portion 206, the bottom shell 202 may include a first fixing hole 180, the third connecting portion 206 may have a second fixing hole, and the first fixing hole 180 and the second fixing hole may be connected by screws. Of course, the top shell 201 and the bottom shell 202 may also be connected by a snap-fit ​​structure.

[0163] In the embodiment of the present application, the structure of the rotating member 110 is not limited. For example, the rotating member 110 may be a columnar structure. For another example, the rotating member 110 may be a disc-shaped structure.

[0164] The rotating member 110 can be rotatably disposed in the accommodating cavity 210 via a rotating shaft structure.

[0165] For example, as shown in Figures 9 and 10, in some embodiments, the shell 200 may also include a third connecting portion 206 arranged in the accommodating cavity 210 along the axial direction of the rotating member 110, and the position corresponding to the rotating member 110 and the third connecting portion 206 has a connecting through hole 270, and the third connecting portion 206 is inserted in the connecting through hole 270 and can rotate in the connecting through hole 270; so that the rotating member 110 is rotatably arranged in the accommodating cavity 210; when the shell 200 includes a first wall body 204 and a second wall body 205, the third connecting portion 206 and the first wall body 204 can be different parts of a structural member; of course, the third connecting portion 206 and the first wall body 204 can also be connected by welding, bonding, etc.; the third connecting portion 206 and the second wall body 205 can be detachably connected by screws or a snap-fit ​​structure so that the rotating member 110 can be installed in the shell 200.

[0166] For example, in other embodiments, the third connecting portion 206 has a connecting protrusion arranged along the axial direction of the rotating member 110, the first wall body 204 and / or the second wall body 205 includes a connecting groove, the connecting protrusion is inserted into the connecting groove, and the connecting protrusion can rotate in the connecting groove, thereby enabling the rotating member 110 to rotate in the accommodating cavity 210.

[0167] In some optional implementations of the embodiments of the present application, as shown in Figures 9 and 10, on the projection plane B perpendicular to the axis A of the rotating member 110, at least part of the projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110, that is, the rotating member 110 is not provided with a space to accommodate the coiled winding segment 132, thereby reducing the axial thickness of the rotating member 110, and the thickness of the shell 200 can be set to be smaller, thereby realizing the lightweight and thinness of the ultra-thin telescopic data cable device.

[0168] In this implementation, on the projection plane B perpendicular to the axis A of the rotating member 110, at least part of the projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110. The projection of the winding segment 132 that is coiled is located outside the projection area of ​​the rotating member 110, or the projection of the winding segment 132 that is not coiled is located outside the projection area of ​​the rotating member 110.

[0169] In this implementation, at least a portion of the projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110, which may mean that the entire projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110. At least a portion of the projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110, which may also mean that a portion of the projection of the winding segment 132 is located outside the projection area of ​​the rotating member 110.

[0170] For example, the rotating member 110 may include: a winding portion 150, the first end of the winding portion 150 is located on the side of the first wall 204, that is, the first end of the winding portion 150 is arranged adjacent to the first wall 204; the fixed section 131 is fixed to the winding portion 150, and the winding section 132 can be arranged to be wound around the circumference of the winding portion 150; on the projection surface B, the projection of the winding section 132 is located outside the projection area of ​​the winding portion 150.

[0171] In this example, the shape of the winding portion 150 is not limited. For example, in some embodiments, the winding portion 150 can be a columnar structure.

[0172] In this example, as shown in Figure 10, the second end of the winding portion 150 is located on the side of the second wall 205, that is, the second end of the winding portion 150 is arranged adjacent to the second wall 205; the rotating member 110 may also include: a positioning portion 160, the positioning portion 160 is arranged at the second end of the winding portion 150; the positioning portion 160 protrudes from the circumferential side of the winding portion 150 along the circumference of the winding portion 150; a portion of the coiled winding segment 132 abuts against the positioning portion 160, and the axial position of the winding segment 132 on the rotating member 110 can be limited by the abutment of the portion of the coiled winding segment 132 with the positioning portion 160, so that the winding segment 132 can be wound in the set area on the circumferential side of the winding portion 150, thereby preventing the winding segment 132 from being too deviated in the axial direction of the winding portion 150. On the projection surface B, part of the projection of the winding segment 132 is located outside the projection area of ​​the positioning portion 160, that is, the positioning portion 160 is used to limit the axial position of the winding segment 132 connected to the fixed segment 131 wound around the winding portion 150, and the other coiled winding segments 132 are mainly located in the space defined by the shell 200, and are limited by the first wall 204 and the second wall 205 of the shell 200.

[0173] The structure of the positioning portion 160 is not limited. For example, in some embodiments, the positioning portion 160 may be a ring-shaped structure. For another example, in other embodiments, the positioning portion 160 may be a strip-shaped structure. For another example, in other embodiments, the positioning portion 160 may be a block-shaped structure.

[0174] The height at which the positioning portion 160 protrudes from the winding portion 150 is not limited. For example, in some embodiments, as shown in FIG10 , the height H1 of the positioning portion 160 protruding from the winding portion 150 is less than the thickness H2 of the winding segment 132 , so as to reduce the installation space of the positioning portion 160 and to limit the axial position of the winding segment 132 at the connection with the fixed segment 131 around the winding portion 150 by the positioning portion 160 .

[0175] Of course, in other implementations, the rotating member 110 may also include only the winding portion 150 but not the positioning portion 160 . In this case, the entire projection of the coiled winding segment 132 is located outside the projection area of ​​the rotating member 110 .

[0176] In an embodiment of the present application, the cable 130 includes a fixed section 131 and a winding section 132; the fixed section 131 is fixed to the rotating member 110, and the winding section 132 can be coiled around the circumference of the rotating member 110, and the coiled winding section 132 is located in the space defined by the shell 200; when the winding section 132 is needed, the winding section 132 can be located outside the shell 200 by pulling the two ends or one end of the cable 130 outside the shell 200, thereby increasing the distance between the first interface portion 320 and the second interface portion 330, so as to be suitable for electrical connection of two external devices with different distances; when the winding section 132 needs to be stored, the winding section 132 can be located inside the shell 200, thereby reducing the distance between the first interface portion 320 and the second interface portion 330, reducing the volume of the ultra-thin telescopic data cable device, so as to facilitate the storage or carrying of the ultra-thin telescopic data cable device.

[0177] The method for securing the fixed section 131 to the rotating member 110 is not limited. For example, in some embodiments, the rotating member 110 may be provided with a clamping groove, through which the fixed section 131 may be secured to the rotating member 110. For another example, in other embodiments, the rotating member 110 may be provided with a clamping structure, through which the fixed section 131 may be secured to the rotating member 110.

[0178] The implementation method of storing the winding section 132 located outside the housing 200 inside the housing 200 is not limited.

[0179] For example, in some embodiments, the cable 130 storage device may further include: an operating member, the operating member is connected to the rotating member 110, and part of the operating member passes through the through slot of the shell 200 and protrudes outside the shell 200. When the operator pulls the two ends of the cable 130 located outside the shell 200 or one end of the cable 130, the rotating member 110 drives the operating member to rotate in the through slot; when the operator stops pulling the two ends of the cable 130 located outside the shell 200 or one end of the cable 130, the rotating member 110 directly stops rotating based on the friction between the shell 200; when it is necessary to store the winding segment 132 located outside the shell 200 in the shell 200, the operating member can be manually rotated so that the operating member drives the rotating member 110 to rotate in the opposite direction, and the winding segment 132 located outside the shell 200 enters the shell 200 from the first opening 161 and the second opening 162 and is stored in the shell 200, and the distance between the first interface portion 320 and the second interface portion 330 is reduced.

[0180] For another example, in some other embodiments, the ultra-thin retractable data cable device may further include: a second elastic member 510, a first end of the second elastic member 510 is fixed to the housing 200, and a second end of the second elastic member 510 is fixed to the rotating member 110 to provide a rotational restoring force to the rotating member 110; that is, when the operator pulls the two ends of the cable 130 located outside the housing 200 or one end of the cable 130, the second elastic member 510 is deformed; when the operator stops pulling the two ends of the cable 130 located outside the housing 200 or one end of the cable 130, the rotating member 110 is deformed based on the positioning structure of the ultra-thin retractable data cable device. The rotation stops due to the positioning effect; when it is necessary to accommodate the winding segment 132 located outside the shell 200 in the accommodating cavity 210, the operator can gently pull the two ends of the cable 130 or one end of the cable 130 located outside the shell 200 again to disengage the rotating member 110 from the positioning effect of the positioning structure of the ultra-thin telescopic data cable device, and rotate in the opposite direction based on the deformation force of the second elastic member 510. The winding segment 132 located outside the shell 200 enters the shell 200 from the first opening 161 or the second opening 162 and is accommodated in the shell 200, and the distance between the first interface portion 320 and the second interface portion 330 is reduced.

[0181] Here, the second elastic member 510 may be a coil spring. A first end of the second elastic member 510 may be fixed to the third connecting portion 206 . A second end of the second elastic member 510 may be clamped to the rotating member 110 .

[0182] Of course, the ultra-thin retractable data cable device can also stop the rotating member 110 from rotating relative to the housing 200 by other means. For example, an external clamping structure can clamp the portion of the winding segment 132 located at the first opening 161 or the second opening 162, so that the clamping structure is locked at the first opening 161 or the second opening 162, thereby preventing the winding segment 132 from entering the housing 200 through the first opening 161 or the second opening 162, thereby stopping the rotating member 110 from rotating relative to the housing 200. When it is necessary to store the winding segment 132 located outside the housing 200 inside the housing 200, the external clamping structure can be removed from the winding segment 132. At this time, the rotating member 110 rotates in the opposite direction based on the deformation force of the second elastic member 510, and the winding segment 132 located outside the housing 200 enters the housing 200 through the first opening 161 or the second opening 162, thereby reducing the distance between the first interface portion 320 and the second interface portion 330. As an example, the clamping structure can be a clip.

[0183] Here, the structure of the positioning structure is not limited.

[0184] In some optional implementations of the embodiments of the present application, the second end of the rotating member 110 has an inner groove 281 and an outer groove 282 that are spaced apart and in an annular shape, as well as an inlet 283 and an outlet 284 that are respectively connected to the inner groove 281 and the outer groove 282; the winding portion 150 also has a card slot 285 at the outlet 284, as shown in Figure 12; the ultra-thin telescopic data cable device may further include: a positioning member 600, the positioning member 600 includes a second seat portion 610 rotatably arranged on the shell 200 and a positioning protrusion 620 protruding from the end surface of the second seat portion 610, the positioning protrusion 620 can be clamped in the card slot 285 to limit the rotational position of the rotating member 110 relative to the shell 200, as shown in Figures 13 and 15.

[0185] In this embodiment, when the operator pulls the two ends of the cable 130 located outside the housing 200 or one end of the cable 130, the rotating member 110 rotates in the first direction A, the positioning protrusion 620 slides in the inner slide groove 281, and the second elastic member 510 is deformed. When the length of the two winding sections 132 of the cable 130 extends to meet the use requirements, the operator can stop pulling the two ends of the cable 130 located outside the housing 200 or one end of the cable 130. At this time, the rotating member 110 rotates in a second direction opposite to the first direction A under the action of the deformation force of the second elastic member 510, and the positioning protrusion 620 slides to the position where it is locked in the slot. 285, so that the rotating member 110 stops rotating relative to the shell 200, thereby ensuring the length of the winding section 132 outside the shell 200; when the winding section 132 needs to be stored, the two ends of the cable 130 outside the shell 200 or one end of the cable 130 are gently pulled to make the positioning protrusion 620 disengage from the slot 285 and enter the outer slide groove 282 from the outlet 284. Under the deformation force of the second elastic member 510, the rotating member 110 continues to rotate in the second direction opposite to the first direction A, so that the winding section 132 outside the shell 200 enters the shell 200 to realize the storage of the winding section 132. When the length of the cable 130 needs to be increased again, the two ends of the cable 130 or one end of the cable 130 located outside the shell 200 can be pulled again. At this time, the rotating member 110 rotates in the first direction A, and the positioning protrusion 620 first slides in the outer slide groove 282 to the entrance 283. Then, the positioning protrusion 620 enters the inner slide groove 281 from the entrance 283 and slides in the inner slide groove 281.

[0186] In this implementation, the shapes of the inner groove 281 and the outer groove 282 are not limited. As long as the rotating member 110 rotates in the first direction A, the positioning protrusion 620 can enter the inner groove 281 from the outer groove 282 through the entrance 283, and when the rotating member 110 rotates in a second direction opposite to the first direction A, the positioning protrusion 620 can be clamped in the clamping groove 285 and can enter the outer groove 282 from the clamping groove 285 through the exit 284.

[0187] For example, as shown in Figures 12 and 13, the rotating member 110 has a first guide protrusion 286 at the inner wall of the inner slide groove 281, and the first guide protrusion 286 is located at the outlet 284, so that the positioning protrusion 620 slides into the slot 285 at the outlet 284; the rotating member 110 has a second guide protrusion 287 at the outer wall of the outer slide groove 282, and the second guide protrusion 287 is located at the entrance 283, so that the positioning protrusion 620 slides from the entrance 283 into the inner slide groove 281.

[0188] In this embodiment, the structure of the second seat portion 610 is not limited. For example, as shown in Figures 14 and 16, the second seat portion 610 can be an annular structure, and the housing 200 further includes a second protrusion 190 inserted into the inner cavity of the second seat portion 610. The second protrusion 190 inserted into the inner cavity of the second seat portion 610 enables the positioning member 600 to be rotatably connected to the housing 200. At the same time, the annular shape of the second seat portion 610 can reduce the installation space of the positioning member 600.

[0189] In some optional implementations of the embodiments of the present application, the ultra-thin telescopic data cable device may further include: a second elastic member 510, the second elastic member 510 is arranged on the rotating member 110, and on the projection plane parallel to the axis of the rotating member 110, at least part of the projection of the second elastic member 510 is located within the projection area of ​​the fixed section 131. At this time, in the thickness direction of the ultra-thin telescopic data cable device, at least part of the second elastic member 510 and the fixed section 131 are arranged in the same space to reduce the setting space of the rotating member 110 in the thickness direction of the ultra-thin telescopic data cable device, thereby realizing the lightweight and thinness of the ultra-thin telescopic data cable device.

[0190] In this implementation, the second elastic member 510 is connected to the housing 200 to provide a rotational restoring force to the rotating member 110 .

[0191] In this implementation, on the projection plane parallel to the axis of the rotating member 110, at least part of the projection of the second elastic member 510 is located within the projection area of ​​the fixed section 131, and the entire projection of the second elastic member 510 is located within the projection area of ​​the fixed section 131. At this time, in the thickness direction of the ultra-thin telescopic data cable device, the second elastic member 510 occupies the setting space of the fixed section 131, and the second elastic member 510 no longer needs to occupy the space of the ultra-thin telescopic data cable device in the thickness direction, thereby realizing the lightweight and thinness of the ultra-thin telescopic data cable device.

[0192] Of course, on the projection plane parallel to the axis of the rotating member 110, at least part of the projection of the second elastic member 510 is located within the projection area of ​​the fixed section 131, and it can also be: part of the projection of the second elastic member 510 is located within the projection area of ​​the fixed section 131; at this time, in the thickness direction of the ultra-thin telescopic data line device, part of the second elastic member 510 occupies the space set by the fixed section 131, and the space occupied by the second elastic member 510 in the thickness direction of the ultra-thin telescopic data line device is reduced, which can realize the ultra-thin telescopic data line device to be lightweight.

[0193] In this embodiment, the first end of the second elastic member 510 can be fixed to the housing 200. The manner in which the first end of the second elastic member 510 is fixed to the housing 200 is not limited. For example, the first end of the second elastic member 510 can be clamped to the third connecting portion 206.

[0194] The second end of the second elastic member 510 can be fixed to the rotating member 110. The implementation method of fixing the second end of the second elastic member 510 to the rotating member 110 is not limited. For example, the second end of the second elastic member 510 can be clamped to the rotating member 110.

[0195] In this implementation, the placement of the second elastic member 510 is not limited. For example, the second elastic member 510 can be positioned at the first end of the rotating member 110, and the fixed section 131 can also be positioned at the first end of the rotating member 110. To prevent the second elastic member 510 from abrading the fixed section 131, one or two baffles can be positioned between the second elastic member 510 and the fixed section 131. As an example, as shown in Figure 11, a partition wall 240 can be positioned between the second elastic member 510 and the fixed section 131.

[0196] Of course, no baffle may be provided between the second elastic member 510 and the fixing section 131 .

[0197] For another example, as shown in Figures 11 and 17, the rotating member 110 may have a second groove 170; the notch of the second groove 170 is located at the first end of the rotating member 110; at least a portion of the second elastic member 510 is disposed in the second groove 170; the first end of the second elastic member 510 is fixed to the shell 200, and the second end of the second elastic member 510 is fixed to the rotating member 110 to provide a rotational restoring force to the rotating member 110; the second groove 170 can protect the second elastic member 510 to prevent other structures from colliding with the second elastic member 510 and affecting the deformation of the second elastic member 510.

[0198] In this example, the first end of the rotating member 110 is located on the side of the first wall 204, and the first end of the rotating member 110 is the end of the rotating member 110 close to the first wall 204. The second end of the rotating member 110 is located on the side of the second wall 205, and the second end of the rotating member 110 is the end of the rotating member 110 close to the second wall 205.

[0199] In this example, the second elastic member 510 may be entirely disposed in the second groove 170 , or may be partially disposed in the second groove 170 .

[0200] In this example, the fixed section 131 of the cable 130 can be fixed in the second groove 170, so that the second groove 170 can both accommodate the second elastic member 510 and fix the fixed section 131, which can simplify the structure of the rotating member 110. Of course, the fixed section 131 of the cable 130 can also be fixed outside the second groove 170.

[0201] The method of fixing the fixing section 131 in the second groove 170 is not limited. For example, the peripheral side of the rotating member 110 further has a first opening 250 communicating with the second groove 170 , and the fixing section 131 is fixed in the second groove 170 through the first opening 250 .

[0202] The number of first openings 250 is not limited. For example, there may be one first opening 250, and the fixing segment 131 may be fixed to the second groove 170 by bonding, snapping, or other means. The two winding segments 132 may be arranged from one first opening 250 around the circumference of the rotating member 110 and located outside the second groove 170. For another example, as shown in Figures 11 and 17, there may be two first openings 250, and the fixing segment 131 may be snapped into the second groove 170 through the two first openings 250. The two winding segments 132 may be arranged from the two first openings 250 around the circumference of the rotating member 110 and located outside the second groove 170.

[0203] In this example, as shown in Figures 11 and 17, the rotating member 110 may also include a partition wall body 240 arranged in the second groove 170, and the number of the first openings 250 is two, and the two first openings 250 are located at both ends of the partition wall body 240; the partition wall body 240 divides the second groove 170 into a first space 171 and a second space 172, and the fixed section 131 is fixed in the first space 171 through the two first openings 250; at least a portion of the second elastic member 510 is arranged in the second space 172; so that the fixed section 131 and the second elastic member 510 are separated by the partition wall body 240 to prevent the fixed section 131 and the second elastic member 510 from affecting each other, for example, the fixed section 131 affects the deformation and movement of the second elastic member 510, and the deformation and movement of the second elastic member 510 wears the fixed section 131.

[0204] As an example, as shown in Figures 11 and 17, the peripheral side of the rotating member 110 also has a second opening 260 that is connected to the second space 172. The first end of the second elastic member 510 is fixed to the shell 200 in the second space 172, and the second end of the second elastic member 510 passes through the second opening 260 and is clamped on the wall of the rotating member 110 located on the peripheral side of the second groove 170.

[0205] Here, the first end of the second elastic member 510 may be locked in the third connecting portion 206 in the second space 172 .

[0206] The second end of the second elastic member 510 may be located outside the second space 172 or within the second space 172. For example, as shown in FIG17 , the second end of the second elastic member 510 is located within the second space 172 through a first opening 250, so that the second end of the second elastic member 510 is fixed by the wall between the first opening 250 and the second opening 260.

[0207] In this example, the rotating member 110 also has an axially arranged connecting through hole 270 at the bottom wall of the second groove 170; the shell 200 also has a third connecting portion 206 inserted into the connecting through hole 270, and the first end of the second elastic member 510 is fixed to the third connecting portion 206.

[0208] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
