[0043] Referring to FIG. 1 to FIG. 5, the cable storage device 100 provided by the embodiment of the present application comprises a shell 1, a winding module 2, a cable 3, a cable head sleeve 4 and a trigger module 5.

[0044] As shown in FIG. 2 and FIG. 4, the shell 1 comprises an outer shell 14 and a support 13, the support 13 is arranged in the outer shell 14, the support 13 is arranged to mount the winding module 2, the cable head sleeve 4 and the trigger module 5, the shape of the support 13 can be set according to actual needs, which is not limited here. The material of the support 13 can be plastic, so that the support 13 is easy to be injection molded into a complex shape. The winding module 2 comprises a winding reel 21, the winding reel 21 is rotatably arranged in the support 13, and the cable 3 can be wound on the winding reel 21.

[0045] As shown in FIG. 4, the cable 3 comprises a wire 31 and a connecting terminal 32 connected with the wire 31, the wire 31 is arranged to transmit electric energy or data, the connecting terminal 32 is arranged to be connected with an electronic device, the type of the connecting terminal 32 can be a type-C interface for example, and the electronic device can be a mobile phone, a tablet computer, a notebook computer, a mobile power supply and the like for example. The wire 31 is usually soft, while the connecting terminal 32 is usually hard, when the winding reel 21 rotates forward, the wire 31 can be wound on the winding reel 21, while the connecting terminal 32 cannot be wound, when the wire 31 is pulled, the winding reel 21 rotates reversely, so that the wire 31 is pulled out, which is convenient for use. Optionally, the winding reel 21 is provided with a winding groove in the circumferential direction, and the wire 31 is wound in the winding groove, so as to prevent the wire 31 from slipping off the winding reel 21.

[0046] As shown in FIG. 4-5, the cable head sleeve 4 is arranged outside the shell 1, the cable head sleeve 4 has an erected position relative to the support 13 and a storage position relative to the support 13. Optionally, the cable head sleeve 4 is rotatably connected with the support 13. As shown in FIG. 4, the cable head sleeve 4 is in the storage position, and as shown in FIG. 5, the cable head sleeve 4 is in the erected position. The cable head sleeve 4 has a first end 43 and a second end 44 away from the first end 43, the first end 43 rotates relative to the shell 1, in the erected position, the second end 44 of the cable head sleeve 4 is away from the shell 1, in the storage position, the second end 44 of the cable head sleeve 4 is close to or abuts against the shell 1. The wire 31 is movably arranged in the cable head sleeve 4, and the connecting terminal 32 is at least partially located at the second end 44 of the cable head sleeve 4.

[0047] The cable storage device 100 of the embodiment of the present application, the first end 43 of the cable sleeve 4 is rotatable relative to the shell 1, the connecting terminal 32 is at least partially located in the second end 44 of the cable sleeve 4, when the cable sleeve 4 is rotated to the storage position, the second end 44 of the cable sleeve 4 is close to the shell 1, that is, the connecting terminal 32 is close to the shell 1, thereby playing a role of storing the connecting terminal 32. When the cable sleeve 4 is rotated to the vertical position, the second end 44 of the cable sleeve 4 is away from the shell 1, that is, the connecting terminal 32 is away from the shell 1, thereby facilitating pulling the connecting terminal 32 to use the cable 3.

[0048] As shown in FIG. 6, the trigger module 5 is arranged on the support 13, the trigger module 5 includes a locking assembly 51 and a first reset member 52, when the cable sleeve 4 is rotated to the vertical position, the locking assembly 51 is limitedly matched with the cable sleeve 4, thereby making the cable sleeve 4 remain in the vertical position, at this time, the wire 31 can be smoothly pulled out. The first reset member 52 is connected with the cable sleeve 4, the first reset member 52 is arranged to drive the cable sleeve 4 to rotate towards the storage position, when the locking assembly 51 is released from the limitation of the cable sleeve 4, the first reset member 52 drives the cable sleeve 4 to rotate from the vertical position to the storage position, the cable sleeve 4 drives the connecting terminal 32 to rotate synchronously, thereby realizing the automatic storage of the connecting terminal 32. Optionally, when the wire 31 is wound on the reel 21, the connecting terminal 32 can drive the locking assembly 51 to move, so as to make the locking assembly 51 released from the limitation of the cable sleeve 4.

[0049] Specifically, when the cable 3 is not needed to be used, the wire 31 is wound on the reel 21, and the cable sleeve 4 is in the storage position which is laid flat relative to the support 13; the connecting terminal 32 is inserted into the cable sleeve 4, thereby making the connecting terminal 32 also in the state of being laid flat relative to the support 13, and the cable sleeve 4 can provide protection for the connecting terminal 32.

[0050] When the cable 3 needs to be used, the cable sleeve 4 is first rotated together with the connecting terminal 32 to stand relative to the support 13, so that the cable sleeve 4 reaches the vertical position, then the connecting terminal 32 is pulled, thereby driving the reel 21 to rotate, so that the wire 31 gradually separates from the reel 21 and is pulled out, after the wire 31 is pulled out to the required length, the connecting terminal 32 is connected with the electronic device to use the cable 3. When the cable sleeve 4 is rotated to the vertical position, the locking assembly 51 can limit the cable sleeve 4, so that the cable sleeve 4 remains in the vertical position, so that the wire 31 is easy to be pulled out.

[0051] When the cable 3 needs to be wound, the connecting terminal 32 is separated from the electronic device, and the winding disc 21 is driven to rotate, the wire 31 is gradually wound on the winding disc 21, the connecting terminal 32 gradually approaches the wire head sleeve 4 and is finally inserted on the wire head sleeve 4, and the connecting terminal 32 abuts against the locking assembly 51, so that the locking assembly 51 is released from the limiting of the wire head sleeve 4. When the wire head sleeve 4 is released from the limiting, the first reset member 52 can drive the wire head sleeve 4 to rotate from the vertical position to the storage position. Because the connecting terminal 32 is inserted on the wire head sleeve 4, the connecting terminal 32 can rotate synchronously with the wire head sleeve 4. When the wire head sleeve 4 rotates to the storage position, the connecting terminal 32 can also rotate to the state of being laid flat relative to the support 13.

[0052] The cable storage device 100 of the embodiment of the application can drive the locking assembly 51 to move to release the limiting of the wire head sleeve 4 by the connecting terminal 32 when the wire 31 is wound on the winding disc 21. The first reset member 52 drives the wire head sleeve 4 released from the limiting to rotate to the storage position. The wire head sleeve 4 drives the connecting terminal 32 to rotate to the state of being laid flat relative to the support 13, so as to realize the automatic storage of the connecting terminal 32 and prevent the connecting terminal 32 from being damaged.

[0053] Please refer to FIGS. 6 to 8. In some embodiments, the wire head sleeve 4 has a limiting portion 42, and the locking assembly 51 includes a limiting member 511, a second reset member 512 and a transmission member 513.

[0054] The limiting member 511 is movably arranged on the support 13. For example, the limiting member 511 is in sliding connection with the support 13. The second reset member 512 is arranged on the support 13 and connected with the limiting member 511. When the wire head sleeve 4 is in the vertical position, the second reset member 512 drives the limiting member 511 to move to limiting cooperation with the limiting portion 42.

[0055] The transmission member 513 is movably arranged on the support 13. For example, the transmission member 513 is slidingly arranged on the support 13, so that the transmission member 513 has support and the movement is more stable. The transmission member 513 is in transmission connection with the limiting member 511. When the connecting terminal 32 drives the transmission member 513 to move, the transmission member 513 overcomes the driving force of the second reset member 512 and drives the limiting member 511 to move, so that the limiting member 511 is released from the limiting of the limiting portion 42. The embodiments of the application do not limit the way of limiting cooperation and releasing limiting between the limiting member 511 and the limiting portion 42.

[0056] Please refer to FIGS. 6-8, in some embodiments, the limiting member 511 includes a limiting column, the limiting portion 42 includes a limiting slot, and the limiting column is inserted into the limiting slot to achieve limiting. The limiting member 511 has a third end 5111 away from the limiting portion 42 and a fourth end 5112 close to the limiting portion 42, the limiting column is in sliding connection with the bracket 13, the second reset member 512 includes a spring, one end of the spring is connected with the bracket 13, and the other end is connected with the third end 5111, and the limiting member 511 can slide along the extension direction of the spring. The limiting portion 42 is located on the inner side wall of the cord sleeve 4, and when the cord sleeve 4 is in the vertical position, part of the bracket 13 is located in the inner side of the cord sleeve 4. When the cord sleeve 4 is rotated from the storage position to the vertical position, the inner wall of the cord sleeve 4 will contact the fourth end 5112 of the limiting column, and the rotating cord sleeve 4 will press against the fourth end 5112, so that the spring will be contracted, and when the cord sleeve 4 is rotated to the vertical position, the fourth end 5112 is aligned with the limiting portion 42, at this time, the restoring force of the spring will push the limiting column towards the limiting slot, so that the fourth end 5112 is inserted into the limiting portion 42 to complete the limiting of the cord sleeve 4.

[0057] Please refer to FIGS. 5-6, in some embodiments, the moving direction of the transmission member 513 is the same as the extension direction of the cord sleeve 4 when the cord sleeve 4 is in the vertical position, and the moving direction of the limiting member 511 is perpendicular to the moving direction of the transmission member 513. By setting the moving direction of the transmission member 513 to be the same as the extension direction of the cord sleeve 4 when the cord sleeve 4 is in the vertical position, when the connecting terminal 32 hits the transmission member 513, the connecting terminal 32 can fully withstand the impact force of the connecting terminal 32, thereby improving the success rate of the disengagement between the limiting member 511 and the limiting portion 42, and further improving the success rate of the automatic storage of the connecting terminal 32.

[0058] Please refer to FIG. 6, in some embodiments, the size of the fourth end 5112 of the limiting member 511 gradually decreases from the third end 5111 to the fourth end 5112, so that the fourth end 5112 of the limiting member 511 can be more easily inserted into the limiting portion 42, which helps to reduce the alignment accuracy requirement between the limiting member 511 and the limiting portion 42. For example, the fourth end 5112 of the limiting member 511 can be an inclined surface, and the design of the inclined surface can make the fourth end 5112 of the limiting member 511 more easily inserted into the limiting portion 42.

[0059] Please refer to FIG. 7, in some embodiments, the connecting terminal 32 has an abutting end surface 32a facing the wire 31, which can be a flat surface or a curved surface. When the wire sleeve 4 is in the vertical position and the connecting terminal 32 is plugged into the wire sleeve 4, the transmission member 513 has a projection on the abutting end surface 32a. That is, when the wire sleeve 4 moves towards the transmission member 513 in the vertical position, the abutting end surface 32a of the wire sleeve 4 can abut against the transmission member 513, so that the wire sleeve 4 can drive the transmission member 513 to move.

[0060] Please refer to FIG. 9, in some embodiments, the transmission member 513 is provided with a strip-shaped slot 513a, and the limiting member 511 is provided with a sliding protrusion which is arranged in the strip-shaped slot 513a along the extension direction of the strip-shaped slot 513a. The transmission member 513 is in transmission connection with the limiting member 511, when the transmission member 513 moves, the strip-shaped slot 513a moves synchronously with the transmission member 513, at this time, the strip-shaped slot 513a abuts against the sliding protrusion to make the sliding protrusion move relative to the strip-shaped slot 513a, the sliding protrusion drives the limiting member 511 to move at the same time, the direction of the movement of the transmission member 513 and the direction of the movement of the limiting member 511 after superposition is the sliding direction of the sliding protrusion relative to the strip-shaped slot 513a, in other words, the extension direction of the strip-shaped slot 513a can be decomposed into the movement direction of the transmission member 513 and the movement direction of the limiting member 511, and the movement direction of the limiting member 511 and the movement direction of the transmission member 513 can be determined according to the extension direction of the strip-shaped slot 513a. Of course, the transmission mode of the transmission member 513 and the limiting member 511 can also be other modes, which are not limited here.

[0061] In some embodiments, when the wire 31 is wound on the reel 21, the connecting terminal 32 abuts against and drives the transmission member 513 to move, and the connecting terminal 32 directly drives the transmission member 513 to move, which can reduce the number of parts and make the structure of the cable storage device simpler.

[0062] Alternatively, the cable storage device 100 further comprises an abutting member, which is arranged on the connecting terminal 32 and abuts against and drives the transmission member 513 to move.

[0063] The abutting member can be a wire sleeve arranged on the connecting terminal 32, the connecting terminal 32 abuts against and drives the transmission member 513 to move through the wire sleeve, and the wire sleeve can protect the connecting terminal 32, thereby prolonging the service life of the connecting terminal 32.

[0064] The abutting member can be a collision protrusion protruding from the connecting terminal 32. The collision protrusion can reduce the abutting area, so that the collision protrusion only abuts against the transmission member 513 and does not abut against the support 13. Therefore, the connecting terminal 32 can sufficiently transmit the force to the transmission member 513, so as to improve the success rate of the disengagement between the limiting member 511 and the limiting portion 42, and further improve the success rate of the automatic storage of the connecting terminal 32.

[0065] In some embodiments, when the pulled-out length of the wire 31 is greater than the first length and the wire 31 is automatically wound by the winding module 2, the connecting terminal 32 can overcome the elastic force of the second reset member 512 and drive the transmission member 513 to move. The first length can be set to be less than the length of the wire 31 that is usually pulled out by the user when using the cable 3. For example, the user generally pulls out at least 5 cm when using the cable 3. Therefore, the first length can be set to 2 cm, 3 cm, 4 cm, etc., which can be set according to the implementation requirements.

[0066] When the pulled-out length of the wire 31 is less than or equal to the first length and the wire is automatically wound by the winding module 2, the connecting terminal 32 cannot drive the transmission member 513 to move. Before pulling out the wire, the user will first rotate the wire end sleeve 4 to the upright position and enable the limiting member 511 to limit the wire end sleeve 4, and then pull out the wire 31. When the wire end sleeve 4 drives the connecting terminal 32 to rotate to the upright state, the winding disc 21 can generate a certain pulling force on the connecting terminal 32, that is, the connecting terminal 32 can generate a certain force on the transmission member 513. By setting the force to be less than the impact force of the connecting terminal 32 on the transmission member 513 when the wire 31 is wound from the first length, the wire end sleeve 4 can be kept in the upright position when the wire 31 is not pulled out.

[0067] Please refer to FIGS. 10 to 13. In some embodiments, the first reset member 52 can be a torsional spring. The first reset member 52 includes an elastic body 521 and a first force arm 522 and a second force arm 523 connected to both ends of the elastic body 521, respectively. The first force arm 522 is connected to the support 13, and the second force arm 523 is connected to the wire end sleeve 4.

[0068] The support 13 is provided with a avoiding slot 1c corresponding to the elastic body 521. The elastic body 521 is arranged in the avoiding slot 1c. The support 13 is provided with a first installation slot 1d corresponding to the first force arm. The first force arm is arranged in the first installation slot 1d. The wire end sleeve is provided with a second installation slot 4a corresponding to the second force arm. The second force arm is arranged in the second installation slot 4a.

[0069] By setting the avoiding groove 1c, the first mounting groove 1d and the second mounting groove 4a, the installation space required by the first reset member 52 can be saved, and the avoiding groove 1c, the first mounting groove 1d and the second mounting groove 4a can limit the elastic body 521, the first force arm 522 and the second force arm 523 respectively, so that the first reset member 52 is not easy to be displaced relative to the wire sleeve 4 and the support 13.

[0070] Optionally, the wire sleeve 4 is rotationally connected with the support 13 through the rotating shaft 41, and the elastic body 521 is sleeved on the rotating shaft 41, thereby saving the installation space.

[0071] In some embodiments, the limiting member 511, the second reset member 512 and the transmission member 513 are all at least partially arranged inside the support 13. Specifically, referring to FIGS. 10-11, the support 13 is internally provided with a first sliding groove 1a and a first sliding groove 1b perpendicular to each other, the limiting member 511 and the second reset member 512 are both arranged in the first sliding groove 1a and are arranged along the extension direction of the first sliding groove 1a, and the transmission member 513 is slidingly arranged in the first sliding groove 1b, the first sliding groove 1b is communicated with the first sliding groove 1a, so that the transmission member 513 can be drivingly connected with the limiting member 511. The transmission member 513 partially protrudes from the first sliding groove 1b, so that the connection terminal 32 can hit the transmission member 513, and the second end of the limiting member 511 protrudes from the first sliding groove 1a, so as to be limitedly matched with the limiting portion 42. By arranging the limiting member 511, the second reset member 512 and the transmission member 513 at least partially inside the support 13, the space occupied by the limiting member 511, the second reset member 512 and the transmission member 513 can be reduced, and the volume of the cable storage device 100 can be reduced.

[0072] Referring to FIGS. 6-7, in some embodiments, the second reset member 512 is partially arranged inside the limiting member 511. For example, the third end 5111 of the limiting member 511 is provided with a guide groove, one end of the second reset member 512 abuts against the groove wall of the first sliding groove 1a, and the other end of the second reset member 512 extends into the guide groove and abuts against the groove wall of the guide groove. By arranging the second reset member 512 partially inside the limiting member 511, the space occupied by the second reset member 512 can be reduced, and the volume of the cable storage device 100 can be reduced.

[0073] Please refer to FIG. 7 and FIG. 14, in some embodiments, the through hole 4b is arranged on the cable head sleeve 4, the size of the wire 31 is smaller than the size of the through hole 4b, when the wire 31 is wound or unwound, the wire 31 can smoothly pass through the through hole 4b, thereby reducing the abrasion of the wire 31. The size of the connecting terminal 32 is larger than the size of the through hole 4b, so that when the wire 31 is wound, the connecting terminal 32 cannot pass through the through hole 4b, avoiding the complete retraction of the cable 3. When the wire 31 is wound to a certain extent, the connecting terminal 32 will be clamped into the through hole 4b and stop moving, so that when the cable 3 is used again subsequently, the user can rotate the cable head sleeve 4 synchronously with the connecting terminal 32 by pulling the connecting terminal 32, and the user can grab the connecting terminal 32 to pull the wire 31. In the storage state, the connecting terminal 32 is still clamped with the cable head sleeve 4, so as to better fix the cable head sleeve 4.

[0074] In some embodiments, when the cable head sleeve 4 is in the vertical position, the size of the through hole 4b near one end of the support 13 is smaller than the size of the through hole 4b away from the support 13, or the size of the connecting terminal 32 near one end of the wire 31 is smaller than the size of the connecting terminal 32 away from the wire 31, so that the connecting terminal 32 can be clamped with the cable head sleeve 4.

[0075] Alternatively, the size of the end of the connecting terminal 32 connected with the wire 31 is smaller than the size of the end of the through hole 4b away from the support 13, so that the end of the connecting terminal 32 connected with the wire 31 can be inside the through hole 4b of the cable head sleeve 4 or pass through the through hole 4b. The size of at least a part of the connecting terminal 32 is larger than the minimum size of the through hole 4b, so that the connecting terminal 32 cannot pass through the through hole 4b completely, thereby enabling the connecting terminal 32 to be clamped with the cable head sleeve 4.

[0076] Please refer to FIG. 4, in some embodiments, the winding module 2 further comprises a third reset member 22 and a locking member, the third reset member 22 is connected with the winding disc 21 and is arranged to drive the winding disc 21 to rotate to a preset position, and the locking member is arranged corresponding to the winding disc 21 and is in limiting cooperation or limiting release with the winding disc 21.

[0077] Alternatively, the third reset member 22 comprises a coil spring, the winding disc 21 comprises a winding drum and a fixed shaft, the fixed shaft is fixedly connected with the support 13, the winding drum is rotationally connected with the fixed shaft, the inner side end of the coil spring is connected with the fixed shaft, and the outer side end of the coil spring is connected with the winding drum, the wire 31 is wound on the outer periphery of the winding drum, when the connecting terminal 32 is pulled, the winding drum rotates, and the coil spring stores energy.

[0078] Optionally, a plurality of locking grooves are circumferentially spaced on the winding drum, and the locking member is rotatably or slidably connected with the support 13. By driving the locking member to rotate or slide, the locking member is clamped in one of the locking grooves, thereby preventing the winding drum from rotating and avoiding the automatic retraction of the cable 3 during use. When it is necessary to store the cable 3, the locking member is driven to disengage from the locking groove, and the winding drum rotates under the action of the coil spring to wind the wire 31.

[0079] It should be noted that when the connecting terminal 32 is inserted into the cable head sleeve 4, the coil spring is still in the energy storage state, thereby preventing the connecting terminal 32 from disengaging from the cable head sleeve 4. At this time, even if the cable head sleeve 4 is in the upright position and the connecting terminal 32 presses against the driving member 513, the force of the coil spring on the connecting terminal 32 is not enough to drive the limiting member 511 to move, and the limiting member 511 can maintain the limiting of the cable head sleeve 4. However, when the cable 3 is wound, the inertial impact force of the connecting terminal 32 strikes the driving member 513, which can drive the limiting member 511 to release the limiting of the cable head sleeve 4.

[0080] Please refer to FIG. 1 and FIG. 13. In some embodiments, the shell 14 has a receiving cavity, and the support 13 includes a first part 11 arranged in the receiving cavity of the shell 14 and a second part 12 extending out of the receiving cavity of the shell 14, the first part 11 is connected with the shell 14, the winding disc 21, etc., and the second part 12 is connected with the cable head sleeve 4, the trigger module 5, etc.

[0081] The shell 14 is provided with a receiving groove 6a corresponding to the second part 12, and the second part 12 is located in the receiving groove 6a. When the cable head sleeve 4 is in the upright position, the cable head sleeve 4 and the connecting terminal 32 are partially located outside the receiving groove 6a. When the cable head sleeve 4 is in the storage position, the cable head sleeve 4 and the connecting terminal 32 are both located in the receiving groove 6a, thereby avoiding damage to the connecting terminal 32 caused by the outward protrusion of the connecting terminal 32.
