[0053] In this embodiment, the housing 10 is provided with an inlet 13 for allowing the wire to be pulled out or reeled into the housing 10. The inlet 13 can be provided on the side wall of the housing 10, and can be located on the first side wall 112 and the second side wall 122.

[0054] like Figure 5As shown, in this embodiment, a winding reel 20 is disposed in the housing 10 and can be used to wind the wire. The winding reel 20 may include a connecting shaft 21, a first winding reel 22, and a second winding reel 23. The connecting shaft 21 may be a cylindrical structure. The first winding reel 22 and the second winding reel 23 are disposed at both ends of the connecting shaft 21. In some embodiments, the first winding reel 22 and the second winding reel 23 may be an integral structure with the connecting shaft 21. A winding space 24 may be formed between the first winding reel 22 and the second winding reel 23. The wire can be stored in the winding space 24 and blocked by the first winding reel 22 and the second winding reel 23 to prevent it from escaping. In this embodiment, the first winding reel 22 and the second winding reel 23 may be disc-shaped. In some embodiments, the first winding reel 22 and the second winding reel 23 may be a separate structure from the connecting shaft 21.

[0055] In this embodiment, the first cable reel 22 may include a reel body 221 and an annular body 222. The reel body 221 is coaxially disposed with the connecting shaft 21, and the annular body 222 is disposed on a side of the reel body 221 opposite to the second cable reel 23. The annular body 222 may protrude from the first reel body 221 and be coaxial with the first reel body 221. The annular body 222 is provided with a locking groove 2221. The two locking grooves 2221 may be disposed opposite each other. Specifically, the two locking grooves 2221 may be arranged radially along the annular body 222.

[0056] In some embodiments, the connecting shaft 21 may be provided with a rotating spring wire extending from the housing 10 at both ends. Pulling one end of the wire drives the rotating spring to rotate, which in turn drives the connecting shaft 21 to receive the wire into the wire take-up space 24 or to pay it out from the wire take-up space 24. In this embodiment, the wire can be paid out from one end or both ends simultaneously, depending on the initial winding method of the wire. The specific structure is the same as that of the prior art and will not be repeated here.

[0057] In this embodiment, the wire storage device further includes a guide and positioning assembly 30, which includes a slider 31 and a positioning member 32. The slider 31 can be connected and fixed to the first cable reel 22, and can rotate on the positioning member 32 along with the first cable reel 22. The positioning member 32 is disposed in the housing 10 and is located between the housing 10 and the first cable reel 22. The positioning member 32 is disposed to one side of the center of the first cable reel 22. Specifically, the positioning member 32 is disposed in a radial direction of the first cable reel 22 and is offset from the center of the first cable reel 22. The positioning member 32 can rotate relative to the first cable reel 22.

[0058] The sliding member 31 may include a connecting portion 311 and a sliding portion 312. One end of the connecting portion 311 may be connected to the first cable reel 22. Specifically, in some embodiments, the connecting portion 311 may be connected to the annular body 222 or the reel body 221. In some embodiments, the connecting portion 311 may be plate-shaped and longitudinally arranged. The sliding portion 312 is disposed on the side of the connecting portion 311 facing the positioning member 32 and is inserted and slidable into the positioning member 32.

[0059] like Figure 6 As shown, in this embodiment, the positioning member 32 may include a main body 321, and the main body 321 may be in the shape of a plate. In this embodiment, the positioning member 32 may be fixedly connected to the housing 10. Specifically, the positioning member 32 may be connected and fixed to the housing 10 by providing a snap-fit ​​structure. Specifically, the main body 321 of the positioning member 32 may be provided with a hook 322 protruding toward the second housing 12, and the hook 322 may be two. The second housing 12 is provided with a latch hole 1211 that cooperates with the latch hook 322, as shown in FIG. Figure 4 As shown, the latch hole 1211 is provided on the second end wall 121 of the second housing 12. There can be two latch holes 1211, which can be provided in a one-to-one correspondence with the two latch hooks 322. When the second housing 12 and the positioning member 32 are assembled, the latch hooks 322 can be engaged with the latch holes 1211.

[0060] In this embodiment, the positioning member 32 has a guide track 323 disposed on the main body 321, with hooks 322 located on opposite sides of the guide track 323. The guide track 323 can cooperate with the sliding member 31 and is a closed guide track 323. In this embodiment, the guide track 323 has at least four inflection points, which are spaced apart. Specifically, the guide track has a first position 323a, a second position 323b, a third position 323c, and a fourth position 323d. The first position 323a, the second position 323b, the third position 323c, and the fourth position 323 are disposed in a one-to-one correspondence with the four inflection points. The first position 323a and the second position 323b are both disposed on the same side and are located near one of the hooks 322. The third position 323c is disposed between the first position 323a and the second position 323b and is approximately located on the centerline of the positioning member 32. The fourth position 323d is positioned adjacent to the other hook 322, between the first position 323a and the second position 323b. The fourth position 323d may be a starting position. The third position 323c may be a fixed position. Driven by the first cable reel 22, the slider 31 can slide between the first position 323a, the second position 323b, and the third position 323c. Specifically, the slider 31 can freely slide from the fourth position 323d toward the first position 323a and then slide from the first position 323a toward the third position 323c; or it can freely slide from the fourth position 323d toward the second position 323b and then slide from the second position 323b toward the third position 323c. In some embodiments, the slider 31 can also slide from the third position 323c toward the first position 323a.

[0061] In this embodiment, the guide rail 323 further includes a first rail 3231, a second rail 3232, a third rail 3233, and a fourth rail 3234. The first rail 3231 is formed between the fourth position 323d and the first position 323a. The second rail 3232 is formed between the fourth position 323d and the second position 323b and communicates with the first rail 3231 at the fourth position 323d. The third rail 3233 is formed between the first position 323a and the second position 323b and communicates with the first rail 3231. The fourth rail 3234 is formed between the third position 323c and the second position 323b and communicates with the third rail 3233 and the second rail 3232. The length of the third rail 3233 is shorter than that of the first rail 3231, and the length of the fourth rail 3234 is shorter than that of the second rail 3232. The slider 31 can slide along the first rail 3231, the second rail 3232, the third rail 3233, and the fourth rail 3234.

[0062] For example Figure 5As shown, in this embodiment, the wire storage device further includes a reset assembly 40 and a locking structure 50. The reset assembly 40 is disposed on the trajectory of relative rotation between the positioning member 32 and the first cable reel 22. When the slider 31 is in the first position 323a, the reset assembly 40 can cooperate with the positioning member 32 to drive the first cable reel 22 to rotate and drive the slider 31 to slide to the third position 323c. When the slider is in the second position 323b, the reset assembly 40 can cooperate with the positioning member 32 to drive the first cable reel 22 to rotate and drive the slider 31 to slide to the fourth position 323d. The locking structure 50 is disposed on the first cable reel 22 and the positioning member 32. When the slider 31 slides to the third position 323c, the first cable reel 22 and the positioning member 32 can be locked by the locking structure 50.

[0063] In this embodiment, the reset assembly 40 further includes a first reset assembly 41 and a second reset assembly 42. Both the first reset assembly 41 and the second reset assembly 42 are disposed on the first cable reel 22 and spaced apart on opposite sides of the positioning member 31 along the relative rotational path of the positioning member 32 and the first cable reel 22. The first reset assembly 41 can be positioned corresponding to the first position 323a or the second position 323b. When the slider 31 is in the first position 323a or the second position 323b, the first reset assembly 41 cooperates with the positioning member 32 to rotate the first cable reel 22 and slide the slider 31 to the third position 323c. The second reset assembly 42 can be positioned corresponding to the fourth position 323d. When the slider 31 slides to the fourth position 323d, the second reset assembly 42 cooperates with the positioning member 32 to drive the first cable reel 22 and slide the slider 31 toward the first position 323a.

[0064] In this embodiment, the first reset assembly 41 may be a first elastic reset assembly. The first elastic reset assembly may include a first fixed end 411 and a first free end 412. The first fixed end 411 may be fixed to the first cable reel 22. Specifically, in some embodiments, the first fixed end 411 may be provided with a first fixing hole 4111, and the first cable reel 22 may be provided with a first fixing post 2211 that is inserted into the fixing hole 4111. The fixing post 2211 is inserted into the first fixing hole 4111 to securely connect the first cable reel 22 to the first elastic reset assembly. The first free end 412 may extend relative to the positioning member 32. When the positioning member 32 abuts the first free end 412, an elastic force is generated. This elastic force drives the first cable reel 22 to rotate, causing the slider 31 to slide to the third position 323c, thereby being locked by the locking structure 50. In this embodiment, the first elastic reset assembly may be a silicone member. Of course, it is understood that in other embodiments, the first elastic reset assembly is not limited to silicone and may also be a rubber member or a spring.

[0065] In this embodiment, the second return assembly 42 may be a second elastic return assembly, which may include a second fixed end 421 and a second free end 422. The second fixed end 421 may be fixed to the first cable reel 22. Specifically, in some embodiments, the second fixed end 421 may be provided with a second fixing hole 4211, and the first cable reel 22 may be provided with a second fixing post 2211 that inserts into the fixing hole 4211. The fixing post 2211 is inserted into the second fixing hole 4211 to securely connect the first cable reel 22 to the second elastic return assembly. The second free end 422 may extend toward the positioning member 32. When the positioning member 32 abuts the second free end 422, an elastic force is generated. This elastic force drives the first cable reel 22 to rotate, causing the slider 31 to slide toward the first position 323a, thereby being locked by the locking structure 50. In this embodiment, the second elastic return assembly may be a silicone member. Of course, it is understood that in other embodiments, the second elastic return assembly is not limited to silicone and may also be a rubber member or a spring.

[0066] In some implementations, the first reset component 41 and / or the second reset component 42 are not limited to elastic reset components. In other embodiments, the first reset component 41 and / or the second reset component 42 may also be a magnetic mechanism. In some embodiments, the reset component 40 is not limited to including two reset components and may also be a single reset component.

[0067] In this embodiment, the locking structure 50 may include a locking groove 2221 and a locking tongue 324 that cooperates with the locking groove 2221. The locking groove 2221 is provided on the outer wall of the annular body 222 and is generally U-shaped or V-shaped. The locking tongue 324 is provided on the side of the positioning member 32 facing the annular body 222. The locking tongue 324 and the third position 323c are both located on the centerline of the positioning member 32. When the sliding member 31 slides to the third position 323c, the locking tongue 324 can be snapped into the locking groove 2221, thereby locking the first cable reel 22 and the positioning member 32, thereby securing the cable and preventing the cable from loosening.

[0068] Specifically, the implementation process of the entire wire storage device is as follows:

[0069] When the wire is recovered, the reel 20 can rotate in the direction F2 to complete the recovery of the wire. When the wire is completely in the take-up space 24, as shown in FIG. Figure 7 As shown, the sliding member 31 stops at the fourth position 323d, and the second free end 421 of the second reset component 42 can abut against the side wall of the positioning member 32 and undergo elastic deformation, thereby generating a driving force to drive the winding wheel 20 to rotate along the F1 direction.

[0070] When the wire is stretched outward, the winding wheel 20 rotates along the F1 direction, and the sliding member 31 can be driven by the first winding drum 22 to rotate to the first position 323a. Figure 8 As shown, the first free end 412 of the first reset assembly 41 can abut against the side wall of the positioning member 32, undergo elastic deformation, and drive the winding wheel 20 to rotate along the F2 direction, so that the sliding member 31 falls into the third position 323c, as shown in FIG. Figure 9 As shown, at this time, the locking tongue 324 on the positioning member 32 is locked in the locking groove 2221 on the first winding drum 22.

[0071] Pulling the wire again can drive the reel 20 to rotate along the F1 direction, and at the same time the sliding member 31 can rotate from the third position 323c to the second position 323b, thereby driving the locking tongue 324 of the positioning member 32 to disengage from the locking groove 2221.

[0072] like Figure 10 As shown, when the sliding member 31 falls into the second position 323b, the first free end 412 of the first reset component 41 can abut against the side wall of the positioning member 32, undergo elastic deformation, continue to pull out the wire, and drive the winding wheel 20 to rotate along the F2 direction, so that the sliding member 31 falls into the fourth position 323d.

[0073] The first reset component 41 and the second reset component 42 can ensure that the winding wheel 20 rotates smoothly and is tightly positioned, and the wire can be reeled in immediately. The first reset component 41 can fix the wire after it is pulled out to a set length, avoiding problems such as loose and disorderly wires or unsatisfactory wire pulling-out lengths.

[0074] Figure 11 and Figure 12 A second embodiment of the wire storage device of the present invention is shown. It differs from the first embodiment in that the first reset assembly 41 includes a first magnetic reset assembly, comprising a first magnetic member 413 and a second magnetic member 414. The first magnetic member 413 is disposed on the first cable reel 22 and located on one side of the positioning member 32. The second magnetic member 414 is disposed on the positioning member 32, proximate to the first magnetic member 413 and facing the first magnetic member 413. When the slider 31 slides to the first position 323a, the distance between the first magnetic member 413 and the second magnetic member 414 decreases, generating a repulsive force between the first magnetic member 413 and the second magnetic member 414, causing the first cable reel 22 to rotate, causing the slider 31 to slide to the third position 323c. The side of the first magnetic member 413 facing the second magnetic member 414 has the same magnetic properties as the side of the second magnetic member 414 facing the first magnetic member 413. In this embodiment, the first magnetic member 413 and the second magnetic member 414 may be magnets.

[0075] In this embodiment, the second reset assembly 42 may be a second magnetic reset assembly, comprising a third magnetic member 423 and a fourth magnetic member 424. The third magnetic member 423 is disposed on the first cable reel 22 and located on the side of the positioning member 32 opposite the first magnetic member 413. The fourth magnetic member 424 is disposed on the positioning member 32 and located on the side facing the third magnetic member 423. When the slider 31 slides to the fourth position 323d, the distance between the fourth magnetic member 424 and the third magnetic member 423 decreases, generating a repulsive force between the third magnetic member 423 and the fourth magnetic member 424, driving the first cable reel 22 to rotate and the slider 31 to slide toward the first position 323a. The surface of the third magnetic member 423 facing the fourth magnetic member 424 has the same magnetic properties as the surface of the fourth magnetic member 424 facing the third magnetic member 423. In this embodiment, the third magnetic member 423 and the fourth magnetic member 424 may be magnets.

[0076] The implementation process of the entire wire storage device of this embodiment can refer to the first embodiment and will not be repeated here.

[0077] Figure 13 and Figure 14 A third embodiment of the wire storage device of the present invention is shown. This embodiment differs from the first embodiment in that there is only one reset assembly 40, which can be a magnetic assembly 43. The magnetic assembly can include a first magnetic member 431 and a second magnetic member 432. The first magnetic member 431 is disposed on the first cable reel 22, and can be positioned near an edge of the first cable reel 22 and between the positioning member 32 and the first cable reel 22. The second magnetic member 432 is disposed on the positioning member 32 and is located midway between the fourth position 323d and the first position 323a, or midway between the fourth position 323d and the second position 323b. Both the first magnetic member 431 and the second magnetic member 432 are bar magnets. The side of the first magnetic member 431 facing the second magnetic member 432 is magnetically opposite to the side of the second magnetic member 432 facing the first magnetic member 431.

[0078] When the slider 31 is in the first position 323a, the attraction between the first magnetic member 431 and the second magnetic member 432 gradually increases, causing the first cable reel 22 to drive the slider 31 to the third position 323c. When the slider 31 is in the fourth position 323d, the attraction between the first magnetic member 431 and the second magnetic member 432 causes the first cable reel 22 to drive the slider 31 toward the first position 323a.

[0079] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
