For example, it can refer to an electrical connection or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium.

It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted.

[0030] The following combination Figures 1 to 9 The wire storage device described in the embodiments of this disclosure will be described in detail.

[0031] The wire storage device may include: a housing 100, a rotating member 200, a wire 300, and an operation key 500. The housing 100 may have a receiving cavity 103; a first opening 101 may be provided on the periphery of the housing 100, and a second opening 102 may be provided on the end side of the housing 100; the rotating member 200 may be rotatably disposed within the receiving cavity 103; the wire 300 may include: a winding section 320 and an end section 310; the winding section 320 is used to wind around the rotating member 200; the end section 310 is connected to the winding section 320 and is located outside the housing 100 through the first opening 101; the operation key 500 may be movably disposed at the second opening 102; the operation key 500 is used to cooperate with the rotating member 200 to limit the rotation of the rotating member 200 relative to the housing 100 in a first direction for storing the wire 300.

[0032] During use, as the rotating member 200 rotates relative to the housing 100, the winding segment 320 of the wire 300 located outside the housing 100 can move through the first opening 101 into the housing 100 and be wound around the rotating member 200; or, the winding segment 320 wound around the rotating member 200 can unfold and move through the first opening 101 to the housing 100. By rotating the rotating member 200 relative to the housing 100, the length of the winding segment 320 of the wire 300 wound around the rotating member 200 can be adjusted, thereby adjusting the length of the wire 300 in the unfolded state for ease of use.

[0033] The inventors discovered that data cable structures include a shell structure and a cable structure. The cable structure often lacks length control during use, resulting in poor stability. The cable storage device of this application, through the cooperation of an operation key 500 and a rotating component 200, can limit the rotation of the rotating component 200 relative to the shell 100 in a first direction for storing the cable 300. In other words, the operation key 500 can prevent the rotating component 200 from rotating relative to the shell 100 in the first direction for storing the cable 300, thereby maintaining a stable length of the cable 300 outside the shell 100 and improving the stability of the cable storage device. Furthermore, since the operation key 500 alone can limit the rotation of the rotating component 200 relative to the shell 100 in the first direction for storing the cable 300, it eliminates the need to stretch the cable 300 to achieve this, preventing damage to the cable 300 and indirectly extending its lifespan. In addition, the operation key 500 can be operated with one hand, making the cable storage device adaptable to one-handed operation scenarios, thereby further improving the adaptability of the cable storage device.

[0034] In this disclosure, the structure of the housing 100 is not limited. For example, in some embodiments, the housing 100 may be a cuboid structure, a cube structure, a circular structure, etc., and this disclosure does not limit this. As an example, such as Figure 1 As shown, the housing 100 may include a first half-shell 104 and a second half-shell 105; the first half-shell 104 and the second half-shell 105 may be connected by means of bonding, snap-fitting, welding, etc. A receiving cavity 103 may be defined between the first half-shell 104 and the second half-shell 105. A first opening 101 may be defined between the first half-shell 104 and the second half-shell 105. The first half-shell 104 may have a second opening 102.

[0035] The number of first openings 101 is not limited. For example, the number of first openings 101 can be one or two. As an example, such as Figure 1 and Figure 2 As shown, the housing 100 may have two first openings 101 communicating with the receiving cavity 103, so that the two ends 310 of the wire 300 can pass through the two first openings 101 respectively.

[0036] It should be noted that in this application, the peripheral side and end side are referenced to the rotation axis of the rotating member 200. The peripheral side can be the circumference of the rotation axis of the rotating member 200, and the end side can be the end side of the rotation axis of the rotating member 200. Here, the peripheral side of the housing 100 can be the portion of the housing 100 corresponding to the peripheral side of the rotation axis of the rotating member 200. The end side of the housing 100 can be the portion of the housing 100 corresponding to the end side of the rotation axis of the rotating member 200.

[0037] In the disclosed embodiments, the structure of the rotating member 200 is not limited. For example, in some embodiments, the rotating member 200 may resemble a disc-shaped structure, a columnar structure, etc., and this disclosure does not limit it in this way.

[0038] The manner in which the rotating member 200 is rotatably disposed within the receiving cavity 103 is not limited. For example, in some embodiments, the rotating member 200 may be rotatably disposed within the receiving cavity 103 via a rotating shaft structure.

[0039] As an example, such as Figure 2 and Figure 5 As shown, a connecting post 710 can be provided in the receiving cavity 103, and the rotating member 200 can have a connecting hole 201. The connecting post 710 passes through the connecting hole 201 and can rotate within the connecting hole 201; thus, the rotating member 200 is rotatably disposed in the receiving cavity 103 by the connecting post 710 passing through the connecting hole 201.

[0040] In this embodiment of the disclosure, the length of the wire 300 can be increased by stretching one end or by stretching both ends.

[0041] As an example, such as Figure 1 and Figure 2 As shown, the two ends 310 of the wire 300 can extend out of the housing 100 through the two first openings 101. Here, the wire storage device may also include a first interface 410 and a second interface 420. The first interface 410 can be set at one end 310 by means of bonding, snapping, welding, etc., and the second interface 420 can be set at the other end 310 by means of bonding, snapping, welding, etc.

[0042] The structure of the first interface component 410 is not limited. For example, the first interface component 410 can be a conductive plate, or it can connect to a male or female connector in the interface. The structure of the second interface component 420 is not limited. For example, the second interface component 420 can be a conductive plate, or it can connect to a male or female connector in the interface.

[0043] In this embodiment of the present disclosure, the operation key 500 is movably disposed at the second opening 102, and the operation key 500 can move relative to the housing 100 so as to move the operation key 500 toward or away from the rotating member 200.

[0044] The operation key 500 is used to cooperate with the rotating member 200 to limit the rotation of the rotating member 200 relative to the housing 100 in a first direction for receiving the wire 300, so that after the wire 300 extends a suitable length outside the housing 100, the operation key 500 prevents the wire 300 from retracting into the housing 100 through the first opening 101.

[0045] The method by which the operation key 500 engages with the rotating member 200 is not limited. For example, the operation key 500 can engage with the rotating member 200 by contacting the end face of the rotating member 200. Alternatively, the operation key 500 can engage with the rotating member 200 by being inserted into a groove on the end face of the rotating member 200.

[0046] In some implementations of the embodiments of this disclosure, the operation key 500 may include an operation part 510 and a first mating part 520. The operation part 510 may be movably disposed at the second opening 102; the first mating part 520 may be disposed on the outer periphery of one end of the operation part 510 located in the receiving cavity 103; the first mating part 520 is used to cooperate with the rotating member 200 to limit the rotation of the rotating member 200 relative to the housing 100 in a first direction for receiving the wire 300.

[0047] In this implementation, the way the first mating part 520 engages with the rotating member 200 is similar to the way the operation key 500 engages with the rotating member 200 described above, and is not limited here. As an example, under the action of an external force, the operation part 510 is used to move closer to the rotating member 200, and the first mating part 520 is used to abut against the rotating member 200. Here, when the external force is large, the first mating part 520 abuts against the rotating member 200 to limit the rotating member 200 from rotating in the first direction; here, the rotating member 200 cannot rotate in the first direction. When the external force is small, the first mating part 520 abuts against the rotating member 200 to limit the speed at which the rotating member 200 rotates in the first direction; here, the rotating member 200 can rotate in the first direction, but the rotation speed is reduced. During use, the magnitude of the external force can be adjusted as needed to control the rotating member 200 to rotate or not rotate. In this implementation, as... Figure 2 and Figure 3As shown, the rotating member 200 may have a limiting groove 202; the first mating part 520 is used to slide within the limiting groove 202; the wire storage device may further include: a guiding mechanism, which may be disposed between the first mating part 520 and the wall of the limiting groove 202; during the rotation of the rotating member 200 relative to the housing 100 in the second direction, the first mating part 520 slides into the limiting groove 202 through the guiding mechanism; during the rotation of the rotating member 200 relative to the housing 100 in the first direction, the first mating part 520 abuts against the wall of the limiting groove to limit the rotation of the rotating member 200 relative to the housing 100 in the first direction of storing the wire 300; wherein, the second direction is opposite to the first direction.

[0048] During the stretching of the wire 300, the rotating member 200 rotates relative to the housing 100 in the second direction. Due to the action of the guiding mechanism, the first mating part 520 can slide into the limiting groove 202 and slide out of the limiting groove. This process is repeated. Because the first mating part 520 repeatedly enters the limiting groove 202, it can provide damping force for the rotation of the rotating member 200 relative to the housing 100 in the second direction, thereby reducing the speed of stretching the wire 300. This allows the wire 300 to extend out of the housing 100 more slowly and smoothly, preventing the speed at which the wire 300 extends out of the housing 100 from being too fast and making it impossible to control the stretching length. After the length of the wire 300 stretched out of the housing 100 is basically determined, the rotating member 200 rotates a certain distance in the opposite direction relative to the housing 100 in the first direction. The first mating part 520 is used to abut against the wall of the limiting groove, thereby preventing the rotating member 200 from rotating relative to the housing 100 in the first direction of receiving the wire 300, so that the wire 300 is stably maintained at the current usable length.

[0049] The first and second directions are not limited. For example, the first direction can be clockwise and the second direction can be counterclockwise. Or, for another example, the first direction can be counterclockwise and the second direction can be clockwise.

[0050] The form of the guiding mechanism is not limited. For example, such as... Figure 3 and Figure 4 As shown, the guiding mechanism may include a first guide slope 521, which may be disposed on one side of the first mating part 520. During the rotation of the rotating member 200 relative to the housing 100 in the second direction, the first mating part 520 can slide into the limiting groove through the first guide slope 521. Through the guiding effect of the first guide slope 521, the first mating part 520 can slide into the limiting groove relatively smoothly. The first guide slope 521 may be located on the side of the first mating part 520 facing the rotating member 200. For example, as... Figure 9As shown, the guiding mechanism may include a second guide slope 241, which may be disposed on the wall of the limiting groove 202. During the rotation of the rotating member 200 relative to the housing 100 in the second direction, the first mating part 520 can slide into the limiting groove through the second guide slope 241. The first mating part 520 can slide into the limiting groove smoothly due to the guiding effect of the second guide slope 241. The second guide slope 241 may be disposed on the side of the wall of the limiting groove 202 opposite to the operating part 510. For example, the guiding mechanism may include a first guide slope 521 and a second guide slope 241. The first guide slope 521 and the second guide slope 241 have been described in the above example and will not be repeated here.

[0051] The number of limiting slots 202 is not limited. For example, the number of limiting slots 202 can be one, at least two, at least three, at least four, etc. As an example, Figure 3 and Figure 4 As shown, the number of limiting grooves 202 can be at least two, and the at least two limiting grooves 202 can be evenly arranged around the rotation axis of the rotating member 200; the number of first mating parts 520 can be at least two, and the positions of the at least two first mating parts 520 correspond to the positions of the at least two limiting grooves 202 respectively; here, each first mating part 520 corresponds to one limiting groove 202. When one first mating part 520 enters one limiting groove 202, the other first mating parts 520 also enter the corresponding limiting grooves 202, so that the force on the circumference of the rotating member 200 is uniform, thereby improving the smoothness of the rotation of the rotating member 200 and preventing the rotating member 200 from jamming.

[0052] In this implementation, the operation key 500 may include a second mating part 530, which may be disposed on the outer periphery of one end of the operation part 510 located in the receiving cavity 103; the other end of the operation part 510 is exposed through the second opening 102, and the distance between the second mating part 530 and the other end of the operation part 510 is greater than the distance between the first mating part 520 and the other end of the operation part 510; under the action of external force, the operation part 510 is used to move towards the rotating member 200, the first mating part 520 is offset from the wall of the limiting groove 202 and can enter the limiting groove 202, and the second mating part 530 is used to abut against the rotating member 200 to limit the speed at which the rotating member 200 rotates in the first direction; thereby, by the second mating part 530 abutting against the rotating member 200, the speed at which the rotating member 200 rotates in the first direction can be reduced, preventing the rotating member 200 from rotating too fast in the first direction and causing the end 310 of the wire 300 located outside the housing 100 to hit the operator's hand.

[0053] Here, because the first mating part 520 is offset from the wall of the limiting groove 202 and can enter the limiting groove 202, the first mating part 520 will not abut against the wall of the limiting groove 202, and will not restrict the rotation of the rotating part 200 relative to the housing 100 in the first direction of receiving the wire 300. This allows the rotating part 200 to rotate in the first direction of receiving the wire 300. The greater the external force, the greater the force of the second mating part 530 abutting against the rotating part 200, and the greater the resistance to the rotation of the rotating part 200 in the first direction of receiving the wire 300. Therefore, the speed of the rotating part 200 can be adjusted by the magnitude of the external force. When the external force is large, the rotating part 200 relative to the housing... Since the housing 100 cannot rotate in the first direction of storing the wire 300, the second mating part 530 can both adjust the speed at which the rotating part 200 rotates relative to the housing 100 in the first direction of storing the wire 300 and limit the rotation of the rotating part 200 relative to the housing 100 in the first direction of storing the wire 300. This achieves the ability to limit the rotation of the rotating part 200 relative to the housing 100 in the first direction of storing the wire 300 by the first mating part 520 and by the second mating part 530, thus greatly improving the adaptability of the wire storage device.

[0054] Of course, in another example, the operation key 500 may also include only the operation part 510 and the second mating part 530 to simplify the structure of the cable storage device.

[0055] The number of the second mating parts 530 is not limited. For example, the number of the second mating parts 530 can be one, at least two, at least three, etc. As an example, Figure 5 and Figure 6 As shown, the number of second mating parts 530 can be at least two, and at least two second mating parts 530 can be evenly arranged along the circumference of the operating part 510 to improve the uniformity of the mating between the second mating parts 530 and the rotating member 200, thereby improving the smoothness of the rotation of the rotating member 200.

[0056] The shape of the second mating part 530 is not limited. For example, the second mating part 530 may be strip-shaped, block-shaped, etc. The shape of the first mating part 520 is not limited. For example, the first mating part 520 may be strip-shaped, plate-shaped, etc.

[0057] For example, such as Figure 7 and Figure 8 As shown, the second mating part 530 can be arranged in a ring shape along the circumference of the operating part 510, and the first mating part 520 can be arranged in a strip shape along the direction away from the circumference of the operating part 510.

[0058] In this example, the first mating part 520 and the second mating part 530 can be staggered or partially overlapped in the moving direction of the operating part 510. As an example, such as... Figure 7 and Figure 8 As shown, the second mating part 530 and the first mating part 520 are circumferentially offset in the operation part 510. Here, the first mating part 520 and the second mating part 530 can be offset in the movement direction of the operation part 510.

[0059] In this example, the second mating part 530 may have a second setting angle A2 in the circumferential direction of the operating part 510, and the value of the second setting angle A2 is not limited. The first mating part 520 may have a first setting angle A1 in the circumferential direction of the operating part 510, and the value of the first setting angle A1 is not limited. As an example, the first setting angle A1 may be less than the second setting angle A2. Of course, the first setting angle A1 may also be equal to or greater than the second setting angle A2.

[0060] Of course, the operation key 500 can also limit the speed at which the rotating member 200 rotates in the first direction in other ways. For example, under the action of an external force, the operation part 510 moves towards the side closer to the rotating member 200, the first mating part 520 is offset from the wall of the limiting groove 202 and can enter the limiting groove 202, and the first mating part 520 abuts against the rotating member 200 to limit the speed at which the rotating member 200 rotates in the first direction. Here, the way in which the first mating part 520 limits the speed at which the rotating member 200 rotates in the first direction is similar to the way in which the second mating part 530 limits the speed at which the rotating member 200 rotates in the first direction. Here, the second mating part 530 can be omitted to simplify the structure of the wire storage device.

[0061] In this implementation, the formation method of the limiting groove 202 is not limited. For example, as Figure 2 and Figure 9 As shown, the rotating component 200 may include: a cylindrical portion 210, an end plate portion 220, an annular portion 230, and a limiting plate 240; a portion of the wire 300 may be fixed inside the cylindrical portion 210 by means of bonding, snapping, welding, etc.; the winding section 320 is used to wind around the outside of the cylindrical portion 210; the end plate portion 220 may be disposed at one end of the cylindrical portion 210; the annular portion 230 may be disposed at one end of the end plate portion 220 away from the cylindrical portion 210; the limiting plate 240 may be disposed on the inner side of the annular portion 230; a limiting groove 202 may be defined between the limiting plate 240 and the end plate portion 220.

[0062] Here, the cylindrical part 210, the end plate part 220, the annular part 230 and the limiting plate 240 can be different parts of a single structural component or different structural components.

[0063] Here, as Figure 7 As shown, a first guide slope 521 is provided on the side of the first mating part 520 corresponding to the limiting plate 240. During the rotation of the rotating member 200 relative to the housing 100 in the second direction, the first mating part 520 is used to slide into the limiting groove through the first guide slope 521, so that the limiting plate 240 does not affect the rotation of the rotating member 200 relative to the housing 100 in the second direction. Alternatively, a second guide slope 241 is provided on one side of the limiting plate 240; during the rotation of the rotating member 200 relative to the housing 100 in the second direction, the first mating part 520 is used to slide into the limiting groove through the second guide slope 241; wherein, the second direction is opposite to the first direction. The first guide slope 521 and the second guide slope 241 have been described in the above embodiments, and will not be repeated here.

[0064] In some implementations of the embodiments of this disclosure, the wire storage device may further include: a second elastic member 620, which may be disposed between the rotating member 200 and the housing 100; the second elastic member 620 is used to provide a force to the rotating member 200 to rotate in a first direction, thereby enabling the wire 300 to automatically rotate in the storage direction through the second elastic member 620.

[0065] The structure of the second elastic element 620 is not limited. For example, the second elastic element 620 can be a coil spring. One end of the second elastic element 620 can be connected to the rotating member 200 by means of bonding, snap-fitting, welding, etc. The other end of the second elastic element 620 can be connected to the housing 100 by means of bonding, snap-fitting, welding, etc. As an example, the other end of the second elastic element 620 can be connected to the connecting post 710 by means of bonding, snap-fitting, welding, etc., to achieve connection with the housing 100.

[0066] In some implementations of the embodiments of this disclosure, the wire storage device may further include: a first elastic member 610, which may be disposed between the operation key 500 and the housing 100; the first elastic member 610 is used to provide a force to the operation key 500 to move in a direction separate from the rotating member 200, so that the operation key 500 does not affect the rotation of the rotating member 200.

[0067] Under the action of the first elastic element 610, the operation key 500 may not abut against the rotating element 200, and the operation key 500 does not limit the speed at which the rotating element 200 rotates relative to the housing 100 in the first direction of receiving the wire 300. Under the action of an external force, the operation key 500 may abut against the rotating element 200 to limit the speed at which the rotating element 200 rotates relative to the housing 100 in the first direction of receiving the wire 300.

[0068] For example, the operation key 500 may include an operation part 510, a first mating part 520, and a second mating part 530, and the rotating member 200 has a limiting groove 202. When the wire 300 is being stretched, the first elastic member 610 prevents the second mating part 530 from contacting the rotating member 200, and the first mating part 520 can slide within the limiting groove 202 to reduce the speed at which the rotating member 200 rotates in the second direction, making the stretching of the wire 300 more stable. Once the wire 300 has been stretched to a certain length, it can be stopped from being stretched further. The second elastic element 620 allows the rotating element 200 to rotate in the first direction for storing the wire 300. The first mating part 520 abuts against the wall of the limiting groove 202 to limit the rotation of the rotating element 200 relative to the housing 100 in the first direction for storing the wire 300, thereby ensuring that the wire 300 stably maintains its current length. When it is necessary to store the wire 300, the operation key 500 can be pressed with external force to allow the first mating part 520 to slide within the limiting groove 202 without affecting the storage of the wire 300, and to allow the second mating part 530 to abut against the rotating element 200. The speed at which the rotating component 200 rotates in the first direction is limited. Once the wire 300 is retracted, the external force applied to the operation key 500 can be released. Thus, the operation key 500 can limit the speed at which the rotating component 200 rotates relative to the housing 100 in the second direction of stretching the wire 300, as well as the speed at which the rotating component 200 rotates relative to the housing 100 in the first direction of retracting the wire 300. This greatly improves the adaptability of the rotating component 200 to rotate relative to the housing 100 in the first direction of retracting the wire 300.

[0069] In this implementation, the specific location of the first elastic element 610 is not limited. For example... Figure 1 and Figure 2 As shown, the rotating member 200 may have a connecting hole 201 in the axial direction; the operation key 500 is located on one side of the connecting hole 201 in the axial direction of the rotating member 200; the wire storage device may further include: a connecting post 710, the connecting post 710 being fixed in the receiving cavity 103; the connecting post 710 passing through the connecting hole 201 so that the rotating member 200 is rotatably disposed in the receiving cavity 103; and a first elastic member 610 being disposed between the connecting post 710 and the operation key 500.

[0070] In this implementation, such as Figure 2 and Figure 6As shown, the connecting post 710 can be cylindrical, and the operating key 500 can be cap-shaped, with the opening of the space defined by the operating key 500 facing the connecting post 710. One end of the first elastic member 610 can be inserted into the cavity of the connecting post 710, and the other end of the first elastic member 610 can be inserted into the space defined by the operating key 500. This prevents the first elastic member 610 from deflecting or bending, thereby improving the deformation stability of the first elastic member 610. Simultaneously, it also increases the length of the first elastic member 610 along the rotation axis of the rotating member 200, thereby improving the deformation capacity of the first elastic member 610. Of course, in other examples, one end of the first elastic member 610 can also be connected to or abut against the end face of the connecting post 710. The other end of the first elastic member 610 can also be connected to or abut against the end face of the operating key.

[0071] Here, as Figure 6 As shown, the end of the connecting post 710 facing the operation key 500 may have a groove 711 in the axial direction; the operation key 500 may include: an operation part 510 and a protrusion 540, the operation part 510 may be movably disposed at the second opening 102; the operation part 510 may be cap-shaped, and the opening of the space defined by the operation part 510 faces the connecting post 710; the other end of the first elastic member 610 may be inserted into the space defined by the operation part 510; the protrusion 540 may be disposed in the cavity of the operation part 510 and inserted into the groove 711 to limit the rotation of the operation part 510 relative to the housing 100. When the operation part 510 moves relative to the housing 100, the protrusion 540 slides in the groove 711, so that the operation key 500 only moves relative to the housing 100 along the rotation axis direction of the rotating member 200, preventing the operation key 500 from rotating relative to the housing 100. Of course, in other examples, the rotation of the operating part 510 relative to the housing 100 can also be limited by providing slides and protrusions on the outside of the second opening 102 and the operating part 510.

[0072] The number of grooves 711 and protrusions 540 is not limited. For example, there may be at least two grooves 711, which may be evenly distributed around the connecting post 710; there may be at least two protrusions 540, which may be inserted into at least two grooves 711 respectively; here, each protrusion 540 is inserted into one groove 711, and when the operating part 510 moves relative to the housing 100, each protrusion 540 being inserted into one groove 711 can improve the smoothness of the movement of the operating key 500.

[0073] The various specific technical features described in the embodiments of this disclosure can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the various specific technical features in the embodiments of this disclosure will not be described separately.

Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
