Designs

[0029] The technical solutions of the present application are explained in more detail below with reference to the drawings of the description and the specific embodiments.

[0030] In the descriptions of the embodiments of this application, it should be noted that the term "connection" is to be understood in the broadest sense, unless otherwise specified and limited; for example, it may refer to an electrical connection, an internal connection between two elements, a direct connection, or even an indirect connection via an intermediate medium. The specific meaning of the aforementioned terms can be understood by a person skilled in the art depending on the specific circumstances.

[0031] It should be noted that the terms "first / second / third" used in the embodiments of this application serve only to distinguish similar objects and do not represent a specific order of the objects; it is understood that "first / second / third" may be interchangeable with respect to their specific order or priority under suitable circumstances. It is understood that the objects distinguished by "first / second / third" may be interchangeable under suitable circumstances, so that the embodiments of this application described herein may be implemented in a different order than that shown or described here.

[0032] The cable storage device 100, data cable device and ultra-thin retractable data cable device described in the embodiments of the present application are described below with reference to Fig. Items 1 to 17 are explained in detail.

[0033] The cable storage device 100 comprises a rotating element 110 and a cable 130. The cable 130 comprises a fastening segment 131 and a winding segment 132. The fastening segment 131 is attached to the rotating element 110, and the winding segment 132 can be wound around the outside of the fastening segment 131.

[0034] In the prior art, cables typically lack a storage structure. They are placed directly on the desk or in a school bag, often becoming tangled with other items. Before use, the cable must first be untangled, increasing the time required and resulting in a poor user experience. In contrast, the cable storage device 100 of the present application comprises a cable 130 with a fastening segment 131 and a winding segment 132. The fastening segment 131 is attached to the rotating element 110, and the winding segment 132 can be wound around the outside of the fastening segment 131.This prevents the cable 130 from becoming tangled with other objects, thus saving the time required to untangle the cable 130 from tangled objects and thereby improving the user experience with the cable 130.

[0035] In the embodiments of the present application, the manner in which the fastening segment 131 is attached to the rotating element 110 is not limited. For example, the fastening segment 131 can be attached to the rotating element 110 by means of a snap-fit ​​structure or an adhesive.

[0036] As a further example, the rotating element 110 comprises a first base section 111 and a first connecting section 112. The first base section 111 has a storage space 1113. The first connecting section 112 is arranged along the axial direction of the rotating element 110 in the storage space 1113. The cable storage device 100 also comprises a first rod-shaped element 120, the first rod-shaped element 120 being arranged along the axial direction of the rotating element 110 in the storage space 1113. A first gap is defined between the first rod-shaped element 120 and the first connecting section 112. The cable 130 comprises a fastening segment 131. A first part 1311 of the fastening segment 131 is latched in the first gap, and a second part 1312 of the fastening segment 131 is wrapped around the circumferential side of the first rod-shaped element 120.

[0037] In some examples, the cable storage device comprises a rotating element and a cable, the rotating element generally having a mounting space and a winding space located outside the mounting space. Part of the cable is secured in the mounting space, and the other part of the cable is wound in the winding space. Because a dedicated mounting space must be provided for the cable, the volume of the rotating element is larger, and the installation space required for the rotating element is also larger. However, if a first gap is defined between the first rod-shaped element 120 and the first connecting section 112, the first part 1311 of the mounting segment 131 is snapped into the first gap, and the second part 1312 of the mounting segment 131 is wound around the circumferential side of the first rod-shaped element 120.This allows the fastening segment 131 of the cable 130 to be secured by the first rod-shaped element 120 and the first connecting section 112. The rotating element 110 does not require separate space for securing the fastening segment 131, thus reducing the installation space of the rotating element 110 and miniaturizing the cable storage device 100.

[0038] As in Fig. 1 and Fig. Figure 8 shows that, in the embodiments of the present application, a data cable device is further described which comprises a housing 200 and a cable storage device 100 according to the embodiments of the present application. The housing 200 has a receiving cavity 210 and a second connecting section 220 arranged in the receiving cavity 210. The rotating element 110 is arranged in the receiving cavity 210. The second connecting section 220 is rotatably connected to the first connecting section 112. This allows the rotating element 110 to rotate in the receiving cavity 210 by means of the rotatable connection of the second connecting section 220 to the first connecting section 112.

[0039] The housing 200 can also include two openings 230, each of which is connected to the receiving cavity 210, so that the two free ends of the cable 130 can be arranged outside the housing 200 through the two openings 230. The two openings 230 can be spaced apart along the circumference of the housing 200.

[0040] In one example, the two openings 230 can be arranged on opposite sides of the housing 200.

[0041] The structure of the housing 200 is not limited. For example, the housing 200 can be, as in Fig. Figure 3 shows a top shell 201 and a bottom shell 202. The receiving cavity 210 and the two openings 230 are defined between the top shell 201 and the bottom shell 202. The second connecting section 220 is connected to the top shell 201, and the second connecting section 220 and the bottom shell 202 can also be connected by screws. The housing 200 can also include a cover plate 203, the cover plate 203 being arranged on a side of the bottom shell 202 facing away from the top shell 201, in order to cover the connection area between the bottom shell 202 and the top shell 201 and to make the overall appearance of the data cable device cleaner.

[0042] The implementation, in which the second connecting section 220 is rotatably connected to the first connecting section 112, is not restricted.

[0043] For example, in some embodiments, such as in Fig. Figure 1 shows a through-hole 1121 arranged along the axial direction of the rotating element 110. The second connecting section 220 is inserted into the through-hole 1121 and is rotatable in the through-hole 1121, enabling the rotating element 110 to rotate in the receiving cavity 210.

[0044] As a further example, in other embodiments, the first connecting section 112 has a first projecting column arranged along the axial direction of the rotating element 110. The second connecting section 220 includes a groove. The first projecting column is inserted into the groove and is rotatable in the groove, enabling the rotating element 110 to rotate in the receiving cavity 210.

[0045] In the embodiments of the present application, the structure of the first basic section 111 of the rotary element 110 is not restricted.

[0046] For example, in some embodiments, such as in Fig. Figure 2 shows a first plate section 1111 and a second plate section 1112 arranged at a distance from each other in the axial direction of the rotating element 110. A storage space 1113 is defined between the first plate section 1111 and the second plate section 1112. The first connecting section 112 is connected to the first plate section 1111 and the second plate section 1112. The first rod-shaped element 120 is connected to the first plate section 1111 and the second plate section 1112. This allows the cable 130 to be accommodated between the first plate section 1111 and the second plate section 1112, thus preventing wear of the cable 130. In addition, the plate-shaped structure reduces the weight of the first base section 111, thereby achieving the slim and lightweight design of the rotating element 110.

[0047] The first plate section 1111, the second plate section 1112, and the first connecting section 112 can be different parts of the same structural element. Of course, the first plate section 1111, the second plate section 1112, and the first connecting section 112 can also be different structural elements, in which case the first plate section 1111, the second plate section 1112, and the first connecting section 112 can be joined together by welding or bonding.

[0048] The first rod-shaped element 120 can be connected to the first plate section 1111 and the second plate section 1112 by press fitting, welding or gluing.

[0049] The shape of the first plate section 1111 is not restricted. For example, the first plate section 1111 can have a disk-shaped structure, in which case the axis of the first plate section 1111 can be the axis of rotation of the rotating element 110.

[0050] The shape of the second plate section 1112 is not restricted. For example, the second plate section 1112 can have a disk-shaped structure, in which case the axis of the second plate section 1112 can be the axis of rotation of the rotating element 110.

[0051] The second plate section 1112 and the first plate section 1111 can both have disk-shaped structures, with the diameter of the second plate section 1112 and the diameter of the first plate section 1111 being equal or substantially equal. Of course, the diameter of the second plate section 1112 and the diameter of the first plate section 1111 can also be different.

[0052] Of course, in other embodiments, the first base section 111 can also comprise only the first plate section 1111 or the second plate section 1112, in which case the storage space 1113 is provided on one side of the first plate section 1111 or the second plate section 1112. The first connecting section 112 and the first rod-shaped element 120 can be arranged on the side of the first plate section 1111 or the second plate section 1112.

[0053] The first connecting section 112 serves to connect to the second connecting section 220 of the housing 200 in order to allow rotation of the rotating element 110 relative to the housing 200.

[0054] The structure of the first connecting section 112 is not restricted. For example, in some embodiments, the first connecting section 112 can have a rod-shaped structure. The cross-sectional shape of the first connecting section 112 is not restricted. For example, the cross-section of the first connecting section 112 can be circular, in which case the first connecting section 112 can have a columnar structure. As another example, the first connecting section 112 has a first width direction with a relatively large dimension and a second width direction with a relatively small dimension in the radial direction; that is, the cross-section of the first connecting section 112 is not circular. In one example, the cross-section of the first connecting section 112 is rectangular.In another example, the cross-section of the first connecting section 112 is elliptical, with the surface of the first connecting section 112 being formed as an arcuate surface, thus preventing the first connecting section 112 from wearing down the cable 130. In yet another example, the first connecting section 112 has two opposing flat surfaces and two convex arcuate surfaces on its circumferential side, with each of the two flat surfaces being connected to one of the two convex arcuate surfaces to form a smooth transition on the surface of the first connecting section 112 on its circumferential side and thus preventing the first connecting section 112 from wearing down the cable 130.

[0055] In the embodiments of the present application, the first rod-shaped element 120 is arranged along the axial direction of the rotating element 110 in the storage space 1113. A first gap is defined between the first rod-shaped element 120 and the first connecting section 112 in order to secure the fastening segment 131 of the cable 130 through the first gap.

[0056] The shape of the first rod-shaped element 120 is not restricted. For example, the surface of the first rod-shaped element 120, around which the fastening segment 131 is wound, is formed as an arc. In some examples, the cable storage device comprises a rotating element and a cable, the rotating element generally having a fastening space and a winding space located outside the fastening space. The fastening space and the winding space are connected by a cable locking groove. Part of the cable is secured in the fastening space by the cable locking groove, and another part of the cable is wound in the winding space. The cable can be easily scratched and damaged by the corners of the circumferential side wall of the cable locking groove.The first gap between the first rod-shaped element 120 and the first connecting section 112 is now defined, with the first part 1311 of the fastening segment 131 being snapped into the first gap, and the second part 1312 of the fastening segment 131 being wrapped around the circumferential side of the first rod-shaped element 120. Furthermore, the surface of the first rod-shaped element 120, around which the fastening segment 131 is wrapped, is formed as an arc. This prevents the first rod-shaped element 120 from scratching the cable 130 and ensures the service life of the cable 130.

[0057] In one example, the first rod-shaped element 120 can have a column-shaped structure. The column-shaped structure of the first rod-shaped element 120 not only prevents it from scratching the cable 130, but also reduces the installation space required for the first rod-shaped element 120, thereby reducing the volume of the rotating element 110 and miniaturizing the cable storage device 100.

[0058] As in Fig. As shown in Figure 1, in some optional implementations of the present application, the cable storage device 100 may further comprise a second rod-shaped element 140, wherein the second rod-shaped element 140 is arranged along the axial direction of the rotating element 110 in the storage space 1113. A second gap is defined between the second rod-shaped element 140 and the first connecting section 112. The fastening segment 131 may also comprise a third part 1313, wherein the third part 1313 is arranged at an end of the first part 1311 facing away from the second part 1312. The third part 1313 is latched in the second gap, and the areas of the fastening segment 131 located at both ends of the third part 1313 are arranged around the circumferential side of the first connecting section 112.In this case, the two parts of the fastening segment 131 are locked into the gaps, and the second rod-shaped element 140 allows the fastening segment 131 to be secured more reliably, thus preventing the fastening segment 131 from moving relative to the rotating element 110.

[0059] In this implementation, the shape of the second rod-shaped element 140 is not restricted. For example, the surface of the second rod-shaped element 140 facing the first connection section 112 is designed as an arc surface so that the second rod-shaped element 140 clamps the third part 1313 of the fastening segment 131 through the arc surface, thereby preventing the second rod-shaped element 140 from scratching the cable 130 and ensuring the service life of the cable 130.

[0060] In one example, the second rod-shaped element 140 can have a column-shaped structure. The column-shaped structure of the second rod-shaped element 140 not only prevents it from scratching the cable 130, but also reduces the installation space required for the second rod-shaped element 140, thereby reducing the volume of the rotating element 110 and miniaturizing the cable storage device 100.

[0061] In this implementation, the second rod-shaped element 140 and the first rod-shaped element 120 can be spaced apart along the circumferential direction of the first connecting section 112. For example, the second rod-shaped element 140 and the first rod-shaped element 120 are, as shown in Fig. 1 shown, arranged on opposite sides of the first connecting section 112 to secure the fastening segment 131 of the cable 130 through the opposite sides of the first connecting section 112, so that the fastening segment 131 of the cable 130 is more securely fastened.

[0062] In one example, the first connecting section 112, as in Fig. Figure 1 shows a first lateral direction with a relatively large dimension and a second lateral direction with a relatively small dimension in the radial direction. The first rod-shaped element 120 and the second rod-shaped element 140 are arranged in the second lateral direction on opposite sides of the first connecting section 112, wherein the first connecting section 112, the first rod-shaped element 120 and the second rod-shaped element 140 form a winding structure.The winding segment 132 of the cable 130 is wound along the circumferential direction of the winding structure formed by the first connecting section 112, the first rod-shaped element 120 and the second rod-shaped element 140, so that the dimensions of the wound winding segment 132 are approximated in the first width direction and the second width direction, making the shape of the wound winding segment 132 more like a disc shape and thus approximating the disc shape of the rotating element 110.

[0063] In the embodiments of the present application, the cable 130, as in Fig. 1 and Fig. Figure 8 also includes a winding segment 132. The winding segment 132 is located at both ends of the mounting segment 131 and can be wound around the mounting segment 131 along its circumference, so that both winding segments 132 are accommodated in the storage space 1113. Furthermore, the two winding segments 132 can be pulled out of the housing 200 through the two openings 230 of the housing 200 to increase the effective usable length of the data cable device.

[0064] The cable 130 can also comprise two connection sections 133, each of the two connection sections 133 being connected to an end of one of the two winding segments 132 facing away from the mounting segment 131, and at least a part of each of the two connection sections 133 being located outside the housing 200, so that, if necessary for use of the data cable device, the two connection sections 133 can be plugged into the ports of two different devices, so that the two different devices can transmit signals, charge, etc. via the data cable device.

[0065] Here, the two connection sections 133 can each have only one plug connector or multiple plug connectors, the types of which can be different so that the data cable device can be electrically connected to external devices with different connector types. In one example, one connection section 133 of the two connection sections 133 comprises, as shown in Fig. Figure 8 shows one plug connector, while the other connection section 133 of the two connection sections 133 comprises three plug connectors of different types.

[0066] When the operator pulls on both ends of the cable 130 located outside the housing 200, or on one end of the cable 130 located outside the housing, the rotating element 110 rotates relative to the housing 200, and the two winding segments 132 located inside the housing 200 are pulled out of the housing 200 through the two openings 230, thereby increasing the distance between the two terminal sections 133. If pulling continues on both ends of the cable 130 located outside the housing 200, or on the one end of the cable 130 located outside the housing, the distance between the two terminal sections 133 increases further, so that the data cable device can adaptively adjust the distance between the two terminal sections 133 to match the distance between the two devices to which the two terminal sections 133 are connected.When the distance between the two connection sections 133 is such that both connection sections 133 can be inserted into the terminals of the two devices, the operator can stop pulling on the two ends of the cable 130 located outside the housing 200 or on the one end of the cable 130 located outside the housing. At this point, when the operator stops pulling on the two ends of the cable 130 located outside the housing 200 or on the one end of the cable 130 located outside the housing, the rotation of the rotary element 110 relative to the housing 200 can either be stopped directly, or the rotary element 110 can be locked relative to the housing 200 by means of a positioning assembly 400 of the data cable device.

[0067] For example, in some embodiments, the cable storage device 100 may further include an operating element, wherein the operating element is connected to the rotating element 110 and part of the operating element projects through a hole in the housing 200 and beyond the housing 200. When the operator pulls on both ends of the cable 130 located outside the housing 200, or on one end of the cable 130 located outside the housing, the rotating element 110 causes the operating element to rotate in the hole. When the operator stops pulling on both ends of the cable 130 located outside the housing 200, or on the one end of the cable 130 located outside the housing, the rotating element 110 immediately stops rotating due to the frictional force between it and the housing 200.If the winding segment 132, located outside the housing 200, is to be received in the storage space 1113 of the rotating element 110, the control element can be manually rotated so that it drives the rotating element 110 in the opposite direction. In this process, the winding segment 132, located outside the housing 200, passes through the opening 230 into the housing 200 and is received in the storage space 1113, thus reducing the distance between the two connection sections 133.

[0068] As a further example, in other embodiments, the first base section 111 has a first plate section 1111 and a second plate section 1112, which are spaced apart, in the axial direction of the rotating element 110. As in Fig. As shown in Figure 4, the data cable device can further comprise a first elastic element 310, wherein the first elastic element 310 is arranged on a side of the first plate section 1111 facing away from the second plate section 1112. A first end of the first elastic element 310 is attached to the housing 200 and a second end of the first elastic element 310 is attached to the first plate section 1111 to provide a restoring force for rotation to the rotating element 110. That is, when the operator pulls on both ends of the cable 130 located outside the housing 200 or on one end of the cable 130 located outside the housing, the first elastic element 310 deforms.When the operator stops pulling on the two ends of the cable 130 located outside the housing 200, or on the single end of the cable 130 located outside the housing, the rotating element 110 stops rotating due to the positioning action of the positioning assembly 400 of the data cable device. If the winding segment 132 located outside the housing 200 is to be received in the storage space 1113 of the rotating element 110, the operator can again lightly pull on the two ends of the cable 130 located outside the housing 200, or on the single end of the cable 130 located outside the housing, to release the rotating element 110 from the positioning action of the positioning assembly 400 of the data cable device and rotate it in the opposite direction due to the deformation of the first elastic element 310.In this process, the winding segment 132, located outside the housing 200, passes through the opening 230 into the housing 200 and is received in the storage space 1113, thus reducing the distance between the two connection sections 133.

[0069] The first elastic element 310 can be a coil spring. The first end of the first elastic element 310 can be attached to the second connecting section 220. The side of the first plate section 1111 facing away from the second plate section 1112 can have a mounting wall 1114, wherein the second end of the first elastic element 310 can be snapped onto the mounting wall 1114, as shown in Fig. 4 shown.

[0070] Of course, the data cable device can also stop the rotation of the rotating element 110 relative to the housing 200 in other ways, for example by means of an external clamping structure that clamps onto the part of the winding segment 132 located in the opening 230, so that the clamping structure is locked onto the opening 230, thus preventing the winding segment 132 from entering the housing 200 through the opening 230 and stopping the rotation of the rotating element 110 relative to the housing 200. If the winding segment 132 located outside the housing 200 is to be received in the storage space 1113, the external clamping structure can be removed from the winding segment 132.In this case, due to the deformation of the first elastic element 310, the rotating element 110 rotates in the opposite direction. The winding segment 132, located outside the housing 200, enters the housing 200 through the opening 230 and is received in the storage space 1113, thus reducing the distance between the two connection sections 133. In one example, the clamping structure could be a clamp.

[0071] The structure of the positioning assembly 400 is not restricted in this case.

[0072] For example, the positioning assembly 400, as shown in Fig. 5, Fig. 6 and Fig. Figure 7 shows the following: a drive gear 410, a connecting element 420, a limiting gear 430, and a return element 440. The drive gear 410 is attached to a side of the second plate section 1112 facing away from the first plate section 1111. The connecting element 420 and the limiting gear 430 are rotatably mounted on the lower shell 202 of the housing 200. One end of the return element 440 rests against the connecting element 420, and the other end of the return element 440 is attached to the lower shell 202 of the housing 200. When the cable storage device 100 rotates, it drives the drive gear 410 to rotate. The drive gear 410 is provided with a first groove 411, and the number of first grooves 411 can be one or more. The number of the first slots 411 has a certain influence on the length of the data cable in each positioning.The connecting element 420 is provided with a first projecting section 421, which can engage with the first groove 411. The connecting element 420 is also provided with a second projecting section 422 and a third projecting section 423, which project axially. The limiting gear 430 is rotatably connected to the housing 200, and the limiting gear 430 is located between the first projecting section 421 and the second projecting section 422. The connecting element 420 can pivot in accordance with the motion gear 410 to ensure that the first projecting section 421 and the second projecting section 422 each engage with different limiting grooves 431 in the limiting gear 430, thereby enabling the engagement and disengagement of the first projecting section 421 with the first groove 411.The restoring element 440 rests at one end against the connecting element 420, and the other end of the restoring element 440 is connected to the lower shell 202 of the housing 200. This allows the restoring element 440 to store energy when the drive gear 410 rotates in a first direction and to release energy when the drive gear 410 rotates in a direction opposite to the first direction. The restoring element 440 is located on one side of the connecting element 420 and interacts with the drive gear 410, deforming elastically in accordance with the movement of the drive gear 410. The rotation of the rotating element 110 can drive the drive gear 410 to move, thereby causing the restoring element 440 to deform elastically. This provides the rotating element 110 with a preload force that pivots it to one side or away from the restoring element 440.By rotating the rotary element 110, the cable 130 wound around it can be freely extended or retracted. Through the interaction of the rotary element 110 with the drive gear 410, the rotary element 110 can lock the cable 130 when it is extended to any desired length. Once the user has extended the cable to a suitable length, they can release it immediately. The rotary element 110 interacts with the drive gear 410, the connecting element 420, and the return element 440 to hold the cable 130 at that length, thus facilitating use. It is evident that the design of the interaction between the positioning assembly 400 and the rotary element 110 simplifies the retractable structure of the data cable and effectively improves its practicality.

[0073] As in Fig. 5 and Fig. As shown in Figure 6, the drive gear 410 comprises at least two first grooves 411, wherein the first projection section 421 is designed as a projection that engages with the first grooves 411. The engagement of the first grooves 411 with the first projection section 421 enables, on the one hand, the drive gear 410 to drive the connecting element 420 to pivot, and on the other hand, allows the connecting element 420, after moving a certain distance, to slide out of a first groove 411 and spring back due to the preload force, so that it engages with the next first groove 411. The at least two first grooves 411 ensure that the connecting element 420 does not remain in a state where it does not engage with the first groove 411 for an extended period during the rotation of the drive gear 410, thus preventing the cable 130 from being locked in time.It is evident that the design of the fitting of the first projection section 421 with the first grooves 411 makes the structure of the data cable more rational and the handling smoother.

[0074] Limiting grooves 431 of different depths are spaced apart on the limiting gear 430, wherein the second projecting section 422 and the third projecting section 423 are arranged at both ends of the connecting element 420 and interact with the connecting element 420.

[0075] As in Fig. 5 and Fig. As shown in Figure 7, when the cable 130 is pulled out, the drive gear 410, via the second projecting section 422, drives the connecting element 420 to pivot, so that the second projecting section 422 comes into contact with the limiting gear 430 and drives the limiting gear 430 to rotate. When the pulling is stopped, the spring force of the return element 440 causes the rotating element 110 to rotate back a short distance. At this point, the reverse rotation of the rotating element 110 and the preload force provided by the return element 440 cause the connecting element 420 to pivot back a distance.The second projecting section 422 of the connecting element 420 engages with the limiting groove 431 of the limiting gear 430 and fixes the connecting element 420 in its current position. This, in turn, fixes the motion gear 410, which interacts with the first projecting section 421, in its current position, thus securing the rotating element 110 and the cable 130. When the cable 130 is to be retracted, it is pulled out a suitable distance. The motion gear 410 pivots the connecting element 420 by a certain distance, so that the third projecting section 423 drives the limiting gear 430 to rotate and turns the limiting groove 431 into a predetermined position. When released, the connecting element 420 pivots back due to the reverse rotation of the drive gear 410 and the presence of the preload force, with the third projecting section 423 fitting into the limiting groove 431.At this point, the first projection section 421 no longer fits with the first groove 411 of the motion gear 410, and the motion gear 410 drives the rotary element 110 to reverse rotation, thereby completing the retraction of the cable 130.

[0076] The ultrathin retractable data cable device described in the embodiments of the present application is described below with reference to Fig. 9 to 17 explained in detail.

[0077] The ultra-thin retractable data cable device comprises a housing 200 and a cable storage device according to the embodiments of the present application. The housing 200 has a receiving cavity 210. The rotating element 110 is rotatably arranged in the receiving cavity 210. The cable 130 comprises a fastening segment 131 and a winding segment 132. The fastening segment 131 is attached to the rotating element 110, the winding segment 132 can be wound around the circumference of the rotating element 110, and the wound-up winding segment 132 is located in the space bounded by the housing 200.

[0078] In some examples, the data cable device comprises a housing, a rotating element, and a cable, the rotating element generally having a storage groove for the cable. For example, the rotating element has two opposing walls at its two axial ends, with a storage groove formed between the two opposing walls, thus increasing the thickness of the rotating element in the axial direction. In this case, the housing that accommodates the rotating element must be thicker, resulting in a thicker and heavier overall data cable device. In the ultra-thin retractable data cable device, the cable 130 comprises a mounting segment 131 and a winding segment 132.The mounting segment 131 is attached to the rotating element 110, the winding segment 132 can be wound around the circumference of the rotating element 110, and the wound-up winding segment 132 is located within the space defined by the housing 200. This means that a storage groove is not required on the rotating element 110. The thickness of the rotating element 110 in the axial direction is small, and the thickness of the housing 200 can therefore be reduced, thus achieving the slim and lightweight design of the ultra-thin retractable data cable device.

[0079] In the embodiments of the present application, the thickness direction of the ultrathin retractable data cable device can be the same or substantially the same as the axial direction of the rotating element 110.

[0080] In the embodiments of the present application, the structure of the housing 200 is not restricted. For example, the housing 200 can have a disk-shaped structure.

[0081] As in Fig. As shown in Figure 9, the housing 200 of the ultrathin retractable data cable device can have a first wall 204 and a second wall 205 arranged opposite each other in the thickness direction. The wound winding segment 132 is located in the space bounded by the first wall 204 and the second wall 205. That is, the wound winding segment 132 is bounded by the first wall 204 and the second wall 205 of the housing 200, so that no boundary walls need to be provided along the axial direction on the rotating element 110. This results in a small thickness of the rotating element 110 in the axial direction, a smaller thickness of the housing 200, and the slimness and lightness of the ultrathin retractable data cable device.

[0082] In the thickness direction of the ultra-thin retractable data cable device, there is a gap between the cable 130 and the first wall 204 of the housing 200 and between the second wall 205 of the housing 200, and 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 gap, thereby achieving the slimness and lightness of the ultra-thin retractable data cable device.

[0083] The gap between the cable 130 and the first wall 204 of the housing 200, as well as the second wall 205 of the housing 200, can mean that there is 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 extend and retract freely in the receiving cavity 210 without being worn 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.

[0084] The gap between the cable 130 and the first wall 204 of the housing 200, as well as the second wall 205 of the housing 200, can also mean that there is a first gap between the cable 130 and the first wall 204 of the housing 200, and no gap between the cable 130 and the second wall 205 of the housing 200, so that the cable 130 can extend and retract freely in the receiving cavity 210 without being worn 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.

[0085] The gap between the cable 130 and the first wall 204 of the housing 200, as well as the second wall 205 of the housing 200, can also mean that there is a second gap between the cable 130 and the second wall 205 of the housing 200, and no gap between the cable 130 and the first wall 204 of the housing 200, so that the cable 130 can extend and retract freely in the receiving cavity 210 without being worn 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.

[0086] In this case, there is no further structural element between the first wall 204 and the wound winding segment 132, and there is no further structural element between the second wall 205 and the wound winding segment 132, so that the wound winding segment 132 is directly limited by the first wall 204 and the second wall 205 in the thickness direction of the ultrathin retractable data cable device in order to prevent the wound winding segment 132 from slipping in the thickness direction of the ultrathin retractable data cable device.

[0087] The structure of the first wall 204 is not restricted. For example, in some embodiments, the first wall 204 can have a flat panel structure. As another example, in other embodiments, the first wall 204 can have a curved panel structure.

[0088] The structure of the second wall 205 is not restricted. For example, in some embodiments, the second wall 205 can have a flat panel structure. As another example, in other embodiments, the second wall 205 can have a curved panel structure.

[0089] As in Fig. As shown in Figure 9, the housing 200 also has a first hole 161 and a second hole 162, which are connected to the receiving cavity 210. The number of winding segments 132 can be two, with the two winding segments 132 being arranged at both ends of the mounting segment 131. The cable 130 can also comprise a first terminal section 320 and a second terminal section 330. The first terminal section 320 is connected to one of the two winding segments 132, and at least a portion of the first terminal section 320 extends through the first hole 161 outside the housing 200. The second terminal section 330 is connected to the other of the two winding segments 132, and at least a portion of the second terminal section 330 extends through the second hole 162 outside the housing 200.This allows the ultra-thin retractable data cable device to be pluggably connected via the first connection section 320 to a port of an external first device and via the second connection section 330 to a port of an external second device, thereby enabling an electrical connection between the first and second devices to be established by means of the ultra-thin retractable data cable device in order to realize charging, signal transmission, etc.

[0090] The number of ports of the first port section 320 is not limited. For example, in some embodiments, the first port section 320 may include at least two first ports, the types of which may be the same or different. In one example, the at least two first ports may include at least two types of USB, Type-C, Micro, and Lightning connectors.

[0091] The number of connectors of the second connector section 330 is not limited. For example, in some embodiments, the second connector section 330 may include at least two second connectors, the types of which may be the same or different. In one example, the at least two second connectors may include at least two types of USB connectors, Type-C connectors, Micro connectors, and Lightning connectors.

[0092] The connection type of the first connection section 320 and the connection type of the second connection section 330 can be the same or different. In one example, the first connection section 320 comprises, as shown in Fig. Figure 9 shows a Type-C connector, and the second connector section 330 includes a Type-C connector.

[0093] The first hole 161 and the second hole 162 can be spaced apart along the circumference of the housing 200. In one example, the first hole 161 and the second hole 162 are, as in Fig. 9 shown, arranged on opposite sides of the housing 200.

[0094] The housing 200 can comprise an upper shell 201 and a lower shell 202, wherein the upper shell 201 and the lower shell 202 can be firmly connected by screws, snap-fit ​​structures or the like, and wherein the receiving cavity 210 and the first hole 161 and the second hole 162, which are connected to the receiving cavity 210, are defined between the upper shell 201 and the lower shell 202.

[0095] The upper shell 201 can comprise a first wall 204 and a side wall arranged on the periphery of the first wall 204. The lower shell 202 can comprise a second wall 205 and a side wall arranged on the periphery of the second wall 205. The side wall on the periphery of the first wall 204 and the side wall on the periphery of the second wall 205 define the first hole 161 and the second hole 162.

[0096] The upper shell 201 can include a third connecting section 206. The lower shell 202 can have a first fastening hole 180. The third connecting section 206 can have a second fastening hole. The first fastening hole 180 and the second fastening hole can be connected by screws.

[0097] Of course, the upper shell 201 and the lower shell 202 can also be connected by locking structures.

[0098] In the embodiments of the present application, the structure of the rotating element 110 is not limited. For example, the rotating element 110 can have a column-shaped structure. As another example, the rotating element 110 can have a disc-shaped structure.

[0099] The rotating element 110 can be rotatably arranged in the receiving cavity 210 by means of a rotary axis structure.

[0100] For example, the housing 200 can be used in some embodiments, such as in Fig. 9 and Fig. As shown in Figure 10, the third connecting section 206 also includes a third connecting section 206, which is arranged along the axial direction of the rotating element 110 in the receiving cavity 210. The rotating element 110 has a connecting through-hole 270 at a position corresponding to the third connecting section 206. The third connecting section 206 is inserted into the connecting through-hole 270 and is rotatable within it, thus allowing the rotating element 110 to be rotatably arranged in the receiving cavity 210. If the housing 200 includes the first wall 204 and the second wall 205, the third connecting section 206 and the first wall 204 can be different parts of a structural element. Naturally, the third connecting section 206 and the first wall 204 can also be joined by welding, bonding, or the like.The third connecting section 206 and the second wall 205 can be detachably connected by screws or snap-fit ​​structures in order to mount the rotating element 110 in the housing 200.

[0101] As a further example, in other embodiments the third connecting section 206 has a connecting projection arranged along the axial direction of the rotating element 110, wherein the first wall 204 and / or the second wall 205 comprise a connecting groove, wherein the connecting projection is inserted into the connecting groove and the connecting projection is rotatable in the connecting groove, thereby making the rotating element 110 rotatable in the receiving cavity 210.

[0102] In some optional implementations of the embodiments of the present application, as in Fig. 9 and Fig. As shown in Figure 10, on a projection plane B perpendicular to the axis A of the rotating element 110, at least part of the projection of the winding segment 132 lies outside the projection area of ​​the rotating element 110. That is, the rotating element 110 is not provided with a space for receiving the wound winding segment 132, which reduces the thickness of the rotating element 110 in the axial direction, allows the thickness of the housing 200 to be made smaller, and achieves the slimness and lightness of the ultra-thin retractable data cable device.

[0103] In this implementation, the arrangement in which at least part of the projection of the winding segment 132 on the projection plane B perpendicular to the axis A of the rotating element 110 lies outside the projection area of ​​the rotating element 110 can mean that at least part of the projection of the wound winding segment 132 lies outside the projection area of ​​the rotating element 110, or that at least part of the projection of the unwound winding segment 132 lies outside the projection area of ​​the rotating element 110.

[0104] In this implementation, the arrangement in which at least part of the projection of the winding segment 132 lies outside the projection area of ​​the rotating element 110 can mean that the entire projection of the winding segment 132 lies outside the projection area of ​​the rotating element 110. The arrangement in which at least part of the projection of the winding segment 132 lies outside the projection area of ​​the rotating element 110 can also mean that part of the projection of the winding segment 132 lies outside the projection area of ​​the rotating element 110.

[0105] For example, the rotating element 110 can comprise a winding section 150, wherein a first end of the winding section 150 is arranged on the side of the first wall 204, that is, the first end of the winding section 150 is located adjacent to the first wall 204. The fastening segment 131 is attached to the winding section 150, and the winding segment 132 can be wound around the circumference of the winding section 150. On the projection plane B, the projection of the winding segment 132 lies outside the projection area of ​​the winding section 150.

[0106] In this example, the shape of the winding section 150 is not restricted. For example, in some embodiments, the winding section 150 can have a columnar structure.

[0107] In this example, as in Fig. As shown in Figure 10, a second end of the winding section 150 is arranged on the side of the second wall 205, that is, the second end of the winding section 150 is adjacent to the second wall 205. The rotating element 110 can also include a positioning section 160, the positioning section 160 being arranged at the second end of the winding section 150. The positioning section 160 projects along the circumferential direction of the winding section 150 from the circumferential side of the winding section 150. A portion of the wound winding segment 132 rests against the positioning section 160.By positioning part of the wound winding segment 132 on the positioning section 160, the position of the winding segment 132 in the axial direction of the rotary element 110 can be limited, which allows the winding segment 132 to be wound in a defined area on the circumferential side of the winding section 150 and prevents the winding segment 132 from being displaced too much in the axial direction of the winding section 150. On projection plane B, part of the projection of the winding segment 132 lies outside the projection area of ​​the positioning section 160. That is, the positioning section 160 serves to limit the axial position of the winding segment 132 at the connection point with the fastening segment 131 when winding around the winding section 150, while the remaining wound winding segment 132 is mainly located in the space bounded by the housing 200 and is bounded by the first wall 204 and the second wall 205 of the housing 200.

[0108] The structure of the positioning section 160 is not limited. For example, in some embodiments, the positioning section 160 can have a ring-shaped structure. As another example, in other embodiments, the positioning section 160 can have a rod-shaped structure. As yet another example, in other embodiments, the positioning section 160 can have a block-shaped structure.

[0109] The height by which the positioning section 160 protrudes from the winding section 150 is not limited. For example, in some embodiments, such as in Fig. Figure 10 shows that the height H1, by which the positioning section 160 protrudes from the winding section 150, is smaller than the thickness H2 of the winding segment 132, in order to both reduce the installation space for the positioning section 160 and to limit the axial position of the winding segment 132, which is wound around the winding section 150 at the connection point with the fastening segment 131, via the positioning section 160.

[0110] Of course, in other implementations the rotary element 110 can also comprise only the winding section 150 without the positioning section 160. In this case, the entire projection of the wound winding segment 132 lies outside the projection area of ​​the rotary element 110.

[0111] In the embodiments of the present application, the cable 130 comprises a fastening segment 131 and a winding segment 132. The fastening segment 131 is attached to the rotating element 110, the winding segment 132 can be wound around the circumference of the rotating element 110, and the wound winding segment 132 is located within the space bounded by the housing 200. When the use of the winding segment 132 is required, the winding segment 132 can be positioned outside the housing 200 by pulling on both ends or on one end of the cable 130 located outside the housing, thereby increasing the distance between the first terminal section 320 and the second terminal section 330 to be suitable for the electrical connection between two external devices at different distances.If the winding segment 132 is to be stored, the winding segment 132 can be arranged in the housing 200, thereby reducing the distance between the first terminal section 320 and the second terminal section 330 and reducing the volume of the ultra-thin retractable data cable device, which makes it easier to tidy up or carry the ultra-thin retractable data cable device.

[0112] The manner in which the fastening segment 131 is attached to the rotating element 110 is not limited. For example, in some embodiments, the rotating element 110 may be provided with a clamping groove, whereby the fastening segment 131 can be locked onto the rotating element 110 by means of the clamping groove. As another example, in other embodiments, the rotating element 110 may be provided with a pressure-fitting structure, whereby the fastening segment 131 can be attached to the rotating element 110 by means of the pressure-fitting structure.

[0113] The implementation in which the winding segment 132, located outside the housing 200, is kept inside the housing 200 is not limited.

[0114] For example, in some embodiments, the cable storage device 130 may further include an operating element, wherein the operating element is connected to the rotating element 110 and part of the operating element projects beyond the housing 200 through a through-slot in the housing 200. When the operator pulls on both ends of the cable 130 located outside the housing 200, or on one end of the cable 130 located outside the housing, the rotating element 110 causes the operating element to rotate in the through-slot. When the operator stops pulling on both ends of the cable 130 located outside the housing 200, or on the one end of the cable 130 located outside the housing, the rotating element 110 immediately stops rotating due to the frictional force between it and the housing 200.If the winding segment 132, located outside the housing 200, is to be received inside the housing 200, the control element can be manually rotated so that the control element drives the rotary element 110 in the opposite direction. In this process, the winding segment 132, located outside the housing 200, enters the housing 200 through the first hole 161 and the second hole 162 and is received inside the housing 200, thus reducing the distance between the first terminal section 320 and the second terminal section 330.

[0115] As a further example, in other embodiments, the ultrathin retractable data cable device can also include a second elastic element 510, wherein a first end of the second elastic element 510 is attached to the housing 200 and a second end of the second elastic element 510 is attached to the rotating element 110 to provide the rotating element 110 with a restoring force for rotation. That is, when the operator pulls on both ends of the cable 130 located outside the housing 200 or on one end of the cable 130 located outside the housing, the second elastic element 510 deforms. When the operator stops pulling on both ends of the cable 130 located outside the housing 200 or on the one end of the cable 130 located outside the housing, the rotating element 110 stops rotating due to the positioning effect of the positioning structure of the ultrathin retractable data cable device.To receive the winding segment 132 located outside the housing 200 in the receiving cavity 210, the operator can again gently pull on both ends of the cable 130 located outside the housing 200, or on the single end of the cable 130 located outside the housing, to release the rotating element 110 from the positioning action of the positioning structure of the ultra-thin retractable data cable device and rotate it in the opposite direction due to the deformation force of the second elastic element 510. In this process, the winding segment 132 located outside the housing 200 enters the housing 200 through the first hole 161 or the second hole 162 and is received in the housing 200, thus reducing the distance between the first terminal section 320 and the second terminal section 330.

[0116] The second elastic element 510 can be a coil spring. The first end of the second elastic element 510 can be attached to the third connecting section 206. The second end of the second elastic element 510 can be latched to the rotating element 110.

[0117] Of course, the ultra-thin retractable data cable device can also stop the rotation of the rotating element 110 relative to the housing 200 in other ways, for example, by an external clamping structure that engages the portion of the winding segment 132 located in the first hole 161 or second hole 162, so that the clamping structure is locked onto the first hole 161 or second hole 162, thus preventing the winding segment 132 from entering the housing 200 through the first hole 161 or second hole 162 and stopping the rotation of the rotating element 110 relative to the housing 200. If the winding segment 132, which is located outside the housing 200, is to be retracted into the housing 200, the external clamping structure can be removed from the winding segment 132.In this case, the rotating element 110 rotates in the opposite direction due to the deformation force of the second elastic element 510. The winding segment 132, located outside the housing 200, enters the housing 200 through the first hole 161 or the second hole 162, thus reducing the distance between the first connection section 320 and the second connection section 330. For example, the clamping structure could be a clamp.

[0118] The structure of the positioning structure is not restricted.

[0119] In some optional implementations of the embodiments of the present application, the second end of the rotary element 110 has an inner sliding groove 281 and an outer sliding groove 282, which are spaced apart and annular in shape, as well as an inlet 283 and an outlet 284, which are connected to the inner sliding groove 281 and the outer sliding groove 282, respectively. The winding section 150 also has a locking groove 285 at the outlet 284, as shown in Fig. Figure 12 shows that the ultra-thin retractable data cable device can further comprise a positioning element 600, wherein the positioning element 600 comprises a second base section 610 rotatably mounted on the housing 200, and a positioning projection 620 projecting from the end face of the second base section 610, wherein the positioning projection 620 can be engaged in the detent groove 285 to limit the rotational position of the rotating element 110 relative to the housing 200, as shown in Figure 12. Fig. 13 and Fig. 15 shown.

[0120] In this implementation, the rotating element 110 rotates in a first direction A when the operator pulls on both ends of the cable 130 located outside the housing 200, or on one end of the cable 130 located outside the housing, whereby the positioning projection 620 slides in the inner sliding groove 281 and the second elastic element 510 deforms. When the extended length of the two winding segments 132 of the cable 130 meets the usage requirements, the operator can stop pulling on both ends of the cable 130 located outside the housing 200, or on the one end of the cable 130 located outside the housing.In this case, the rotating element 110 rotates under the influence of the deformation force of the second elastic element 510 in a second direction opposite to the first direction A, whereby the positioning projection 620 slides into the detent groove 285 until it engages, thus stopping the rotation of the rotating element 110 relative to the housing 200 and ensuring the length of the winding segment 132 remains outside the housing 200. To retain the winding segment 132, a gentle pull is applied to either of the two ends of the cable 130 located outside the housing 200, or to the single end of the cable 130 located outside the housing, causing the positioning projection 620 to exit the detent groove 285 and enter the outer sliding groove 282 from the outlet 284.The rotating element 110 continues to rotate in the second direction, opposite to the first direction A, under the influence of the deformation force of the second elastic element 510. This causes the winding segment 132, located outside the housing 200, to move into the housing 200, thus securing the winding segment 132. If the length of the cable 130 needs to be increased again, it can be pulled again on both ends of the cable 130 located outside the housing 200 or on the one end of the cable 130 located outside the housing. In this case, the rotating element 110 rotates in the first direction A, with the positioning projection 620 initially sliding in the outer sliding groove 282 towards the inlet 283. The positioning projection 620 then enters the inner sliding groove 281 at the inlet 283 and slides within the inner sliding groove 281.

[0121] In this implementation, the shape of the inner sliding groove 281 and the outer sliding groove 282 is not restricted, as long as the positioning projection 620 can enter the inner sliding groove 281 from the outer sliding groove 282 via the inlet 283 when the rotating element 110 rotates in the first direction A, and the positioning projection 620 can be engaged in the detent groove 285 and enter the outer sliding groove 282 from the detent groove 285 via the outlet 284 when the rotating element 110 rotates in the second direction, which is opposite to the first direction A.

[0122] For example, the rotary element 110, as shown in Fig. 12 and Fig. As shown in Figure 13, the rotating element 110 has a first guide projection 286 on the inner wall of the inner sliding groove 281, wherein the first guide projection 286 is arranged at the outlet 284, so that the positioning projection 620 at the outlet 284 slides into the detent groove 285. The rotating element 110 has a second guide projection 287 on the outer wall of the outer sliding groove 282, wherein the second guide projection 287 is arranged at the inlet 283, so that the positioning projection 620 at the inlet 283 slides into the inner sliding groove 281.

[0123] In this implementation, the structure of the second base section 610 is not restricted. For example, the second base section 610 can be, as in Fig. 14 and Fig. Figure 16 shows a ring-shaped structure, wherein the housing 200 also includes a second projecting column 190, which is inserted into the inner cavity of the second base section 610. By inserting the second projecting column 190 into the inner cavity of the second base section 610, a rotatable connection between the positioning element 600 and the housing 200 is achieved. At the same time, the ring-shaped second base section 610 can reduce the installation space required for the positioning element 600.

[0124] In some optional implementations of the embodiments of the present application, the ultrathin retractable data cable device may further comprise a second elastic element 510, wherein the second elastic element 510 is arranged on the rotating element 110 and at least part of the projection of the second elastic element 510 lies within the projection area of ​​the mounting segment 131 on a projection plane parallel to the axis of the rotating element 110. In this case, at least part of the second elastic element 510 and the mounting segment 131 are arranged in the same space in the thickness direction of the ultrathin retractable data cable device in order to reduce the installation space of the rotating element 110 in the thickness direction of the ultrathin retractable data cable device and to achieve the slimness and lightness of the ultrathin retractable data cable device.

[0125] In this implementation, the second elastic element 510 is connected to the housing 200 to provide a restoring force for rotation to the rotary element 110.

[0126] In this implementation, the arrangement in which at least part of the projection of the second elastic element 510 lies within the projection area of ​​the mounting segment 131 on a projection plane parallel to the axis of the rotating element 110 can mean that the entire projection of the second elastic element 510 lies within the projection area of ​​the mounting segment 131. In this case, the second elastic element 510 occupies the installation space for the mounting segment 131 in the thickness direction of the ultrathin retractable data cable device, without requiring any additional space in the thickness direction of the ultrathin retractable data cable device, thus achieving the slimness and lightness of the ultrathin retractable data cable device.

[0127] Naturally, the arrangement in which at least part of the projection of the second elastic element 510 lies within the projection area of ​​the mounting segment 131 on a projection plane parallel to the axis of the rotating element 110 can also mean that part of the projection of the second elastic element 510 lies within the projection area of ​​the mounting segment 131. In this case, part of the second elastic element 510 occupies the installation space for the mounting segment 131 in the thickness direction of the ultrathin retractable data cable device, thereby reducing the space occupied by the second elastic element 510 in the thickness direction of the ultrathin retractable data cable device and achieving the slimness and lightness of the ultrathin retractable data cable device.

[0128] In this implementation, a first end of the second elastic element 510 can be attached to the housing 200. The manner in which the first end of the second elastic element 510 is attached to the housing 200 is not restricted. For example, the first end of the second elastic element 510 can be snapped onto the third connecting section 206.

[0129] A second end of the second elastic element 510 can be attached to the rotating element 110. The implementation in which the second end of the second elastic element 510 is attached to the rotating element 110 is not restricted. For example, the second end of the second elastic element 510 can be snapped to the rotating element 110.

[0130] In this implementation, the arrangement position of the second elastic element 510 is not restricted. For example, the second elastic element 510 can be arranged at a first end of the rotary element 110, and the fastening segment 131 can also be arranged at the first end of the rotary element 110. To prevent wear of the fastening segment 131 by the second elastic element 510, one or two separating plates can be arranged between the second elastic element 510 and the fastening segment 131. In one example, as shown in Fig. Figure 11 shows that a partition wall 240 is arranged between the second elastic element 510 and the fastening segment 131.

[0131] Naturally, no separating plate can be arranged between the second elastic element 510 and the fastening segment 131.

[0132] As another example, the rotary element 110, as in Fig. 11 and Fig. Figure 17 shows a second groove 170. The opening of the second groove 170 is located at the first end of the rotating element 110. At least part of the second elastic element 510 is arranged in the second groove 170. The first end of the second elastic element 510 is attached to the housing 200, and the second end of the second elastic element 510 is attached to the rotating element 110 to provide the rotating element 110 with a restoring force for rotation. The second groove 170 protects the second elastic element 510, preventing other structures from colliding with it and thereby impairing its deformation.

[0133] In this example, the first end of the rotating element 110 is located on the side of the first wall 204, wherein the first end of the rotating element 110 is the end of the rotating element 110 facing the first wall 204, and the second end of the rotating element 110 is located on the side of the second wall 205, wherein the second end of the rotating element 110 is the end of the rotating element 110 facing the second wall 205.

[0134] In this example, the second elastic element 510 can be arranged completely in the second groove 170 or partially in the second groove 170.

[0135] In this example, the fastening segment 131 of the cable 130 can be attached in the second groove 170, so that the second elastic element 510 can be received in the second groove 170, and the fastening segment 131 can also be attached there, thus simplifying the structure of the swivel element 110. Of course, the fastening segment 131 of the cable 130 can also be attached to the outside of the second groove 170.

[0136] The manner in which the fastening segment 131 is secured in the second groove 170 is not restricted. For example, the circumferential side of the rotating element 110 also has a first opening 250 which is connected to the second groove 170, with the fastening segment 131 being secured through the first opening 250 in the second groove 170.

[0137] The number of first openings 250 is not limited. For example, the number of first openings 250 is one, where the fastening segment 131 can be fastened in the second groove 170 by gluing, snapping, or the like, and the two winding segments 132 are wound from the one first opening 250 around the circumference of the rotating element 110 and are located outside the second groove 170. As another example, as in Fig. 11 and Fig. 17 shown, the number of first openings 250 is two, wherein the fastening segment 131 is locked into the second groove 170 by the two first openings 250, and the two winding segments 132 are wound around the circumference of the rotating element 110 from the two first openings 250 and are located outside the second groove 170.

[0138] In this example, the rotary element 110 can be used as shown in Fig. 11 and Fig. Figure 17 also includes a partition 240 arranged in the second groove 170, wherein the number of first openings 250 is two and the two first openings 250 are arranged at both ends of the partition 240. The partition 240 divides the second groove 170 into a first space 171 and a second space 172, wherein the fastening segment 131 is fastened through the two first openings 250 in the first space 171. At least part of the second elastic element 510 is arranged in the second space 172 in order to separate the fastening segment 131 and the second elastic element 510 from each other by the partition 240 and to prevent mutual interference between the fastening segment 131 and the second elastic element 510.For example, it prevents the fastening segment 131 from interfering with the deformation movement of the second elastic element 510 or from the deformation movement of the second elastic element 510 wearing out the fastening segment 131.

[0139] In one example, as in Fig. 11 and Fig. As shown in Figure 17, the circumferential side of the rotating element 110 also has a second opening 260 which is connected to the second space 172, wherein the first end of the second elastic element 510 is attached to the housing 200 in the second space 172 and the second end of the second elastic element 510 is latched through the second opening 260 to the wall of the rotating element 110 arranged on the circumferential side of the second groove 170.

[0140] In this case, the first end of the second elastic element 510 can be locked into the third connecting section 206 in the second space 172.

[0141] The outermost end of the second end of the second elastic element 510 can be located outside the second space 172 or inside the second space 172. For example, as in Fig. Figure 17 shows the outermost end of the second end of the second elastic element 510 through one of the first openings 250 within the second space 172, so that the second end of the second elastic element 510 is fastened through the wall between the first openings 250 and the second opening 260.

[0142] In this example, the rotating element 110 also has an axially arranged connecting through-hole 270 on the bottom wall of the second groove 170. The housing 200 also has a third connecting section 206 inserted into the connecting through-hole 270, with the first end of the second elastic element 510 being attached to the third connecting section 206.

[0143] The foregoing describes only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any modifications or replacements that can be readily devised by a person skilled in the art within the scope of technical information disclosed in the present application fall within the scope of protection of the present application.
