When a user needs to connect an electronic device using the cable, the second section of the cable can be pulled out to allow its first end to gradually extend beyond the housing. The winding mechanism rotates accordingly, and simultaneously, a second sound-emitting mechanism collidees with the first sound-emitting mechanism, producing sound as the cable extends and retracts, providing the user with a reference to the cable's length. Furthermore, the collision between the first and second sound-emitting mechanisms increases the rotational resistance of the winding mechanism, preventing excessive speed during cable extraction and retraction.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0049] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0050] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] See appendix Figures 1 to 12 This utility model proposes a cable reel, including a housing 1, a winding mechanism 2, a connecting cable 3, a first sound-generating mechanism 4, and a second sound-generating mechanism 5. The housing 1 has a receiving cavity 100. The winding mechanism 2 includes a drum 21 rotatably mounted within the receiving cavity 100 and a spring 22 connecting the drum 21 to the housing 1. The first end 31 of the connecting cable 3 is wound onto the drum 21, and the second end 32 of the connecting cable 3 extends out of the housing 1. The first sound-generating mechanism 4 includes at least one first impact member 41, which is fixedly mounted on the housing 1 and located within the receiving cavity 100. The second sound-generating mechanism 5 includes at least one second impact member 51, which is mounted on the drum 21.

[0052] The second collision member 51 can rotate with the drum 21 and collide with the first collision member 41 in a cyclical manner, while emitting a sound.

[0053] In some embodiments, at least one of the first collision member 41 and the second collision member 51 can undergo elastic deformation. Therefore, after the first collision member 41 and the second collision member 51 collide, one of them undergoes elastic deformation to allow the winding mechanism 2 to continue rotating.

[0054] Specifically, the cable reel utilizes the winding mechanism 2 to wind up and store the connecting cable 3, reducing its footprint and preventing it from becoming tangled. When the user needs to connect the connecting cable 3 to an electronic device, the second section of the cable 3 can be pulled out, causing its first end 31 to gradually extend beyond the housing. The reel 21 rotates accordingly, and the second sound-emitting mechanism 5 collidees with the first sound-emitting mechanism 4, producing a sound accompanying the extension and retraction of the connecting cable 3. This serves as a reference for the user regarding the cable's length. Furthermore, the collision between the first and second sound-emitting mechanisms 4 and 5 increases the rotational resistance of the reel 21. This requires the user to overcome the elasticity of either the first or second sound-emitting mechanism 5 when pulling the cable 3 or when the spring 22 retracts the cable 3, preventing excessive rotational speed during cable pulling and retraction, and thus preventing the cable 3 from striking the user due to rapid movement.

[0055] To prevent the connecting wire 3 from interfering with the collision between the first sound-generating mechanism 4 and the second sound-generating mechanism 5, in some embodiments, as shown in the attached... Figure 4 and 10 As shown, the first collision member 41 protrudes in the direction of the second collision member 51 along the radial direction of the drum 21, and the second collision member 51 is disposed on both ends of the drum 21 in the axial direction, and the second collision member 51 protrudes in the direction of the first collision member 41 along the radial direction of the drum 21.

[0056] In some embodiments, the first impact member 41 and / or the second impact member 51 are made of metal. For example, the first impact member 41 is entirely made of metal, while the second impact member 51 is made of plastic or has a portion thereof made of metal. This arrangement makes the sound produced when the first impact member 41 and the second impact member 51 collide more crisply and loudly.

[0057] Regarding the structure of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, in some embodiments, the first sound-generating mechanism 4 includes a first impact member 41 protruding from the inner wall of the receiving cavity 100. The second sound-generating mechanism 5 includes a second impact member 51 that rotates with the drum 21. The second impact member 51 will collide with the first impact member 41 once per rotation. This embodiment is not shown in the accompanying drawings.

[0058] Regarding the structure of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, see the appendix for further details in some embodiments. Figure 5 The first sound-generating mechanism 4 includes multiple first collision elements 41, which are arranged in a ring around the circumference of the drum 21 at equal intervals. The second sound-generating mechanism 5 includes a second collision element 51 that rotates with the drum 21, and the second collision element 51 will collide with a first collision element 41 once every certain angle of rotation.

[0059] Specifically, the first sound-generating mechanism 4 also includes a plurality of first mounting members 42 arranged in a ring. These first mounting members 42 are arranged in a ring around the drum, and the resulting structure can be a closed ring or an open ring. A plurality of first collision members 41 are respectively disposed on the plurality of first mounting members 42 and spaced apart from each other. In some examples, as shown in the attached... Figure 5 As shown, multiple first mounting members 42 and multiple first collision members 41 are integrally formed, and multiple grooves 43 are formed on the first mounting members 42. The multiple first collision members 41 are spaced apart by the multiple grooves 43. The surface of the grooves 43 is arc-shaped, and the first collision member 41 is smoothly connected to the grooves 43 on both sides, so that the inner ring surface of the entire first sound-generating mechanism 4 is wavy. Further, the first mounting member 42 extends radially towards the center of the drum 21, so that the first collision member 41 is closer to the center of the drum 21. The extension length of the first mounting member 42 is designed according to the winding thickness of the connecting line 3 to ensure that the first collision member 41 and the second collision member 51 can contact and collide with each other. It should be noted that in other embodiments, as shown in the attached figure Figure 6 As shown, multiple first mounting components are spaced apart from each other, and each first mounting component is integrally mounted with one or more first collision components.

[0060] See appendix Figure 7 The second sound-generating mechanism 5 also includes a second mounting member 52. The second collision member 51 includes a contact portion 511 and an elastic portion 512. The second mounting member 52 is fixedly mounted or integrally disposed on the drum 21. The second mounting member 52 is provided with a movable groove 521 that is radially opened along the drum 21. The movable groove 521 is provided with an opening 522 on the side away from the drum 21. The contact portion 511 is movably mounted in the movable groove 521. The contact portion 511 can at least partially extend out of the opening 522 and collide with the first collision member 41. The elastic portion 512 is located in the movable groove 521 and connects the second mounting member 52 and the contact portion 511.

[0061] For example, in some of these embodiments, such as the appendix Figure 7 As shown, the elastic part 512 is a compression spring, and the contact part 511 is a steel ball. The elastic force of the elastic part 512 is used to drive the contact part 511 out of the opening 522; in other embodiments, as shown in the attached figure Figure 9 As shown, the elastic part 512 is an elastic soft rubber, and the contact part 511 is a metal impact head fitted on the elastic soft rubber; in some embodiments, the elastic part 512 is a metal spring, and the contact part 511 is a metal impact head integrally disposed on the metal spring.

[0062] Specifically, the contact portion 511 collides with the first collision member 41. After the contact portion 511 collides with a first collision member 41, the contact portion 511 moves into the movable groove 521, causing the elastic portion 512 to elastically deform until the contact portion 511 passes the first collision member 41 and enters the range of the groove 43. The elastic portion 512 then extends and resets, applying a spring force towards the groove 43 to the contact portion 511, causing the contact portion 511 to extend out of the opening 522 again. The groove 43 is used to accommodate the portion of the contact portion 511 extending out of the opening 522, so that the contact portion 511 can contact the next first collision member 41.

[0063] Furthermore, the second mounting member 52 has a stop protrusion 523 protruding inward from the opening 522 of the movable groove 521. When the contact portion 511 moves towards the first collision member 41, it can abut against the stop protrusion 523. The function of the stop protrusion 523 is to prevent the contact portion 511 from disengaging from the opening 522 of the movable groove 521.

[0064] For specific settings of the second mounting component 52, please refer to the appendix. Figure 7 In some embodiments, the second mounting member 52 includes a connecting plate 524, two guide protrusions 525, and an extension platform 526. The connecting plate 524 is fixedly connected to the drum 21. The guide protrusions 525 are disposed on the connecting plate 524 and form a movable groove 521 between the two guide protrusions 525. The rear ends 5251 of the two guide protrusions 525 are connected, and an opening 522 is formed between the front ends 5252 of the two guide protrusions 525. Both front ends 5252 of the two guide protrusions 525 are provided with stop protrusions 523. The extension platform 526 connects the front ends 5252 of the two guide protrusions 525 and extends away from the winding mechanism 2, so that the extension platform 526 protrudes from the guide protrusions 525. The function of the extension platform 526 is to strengthen the overall structure of the second mounting member 52 and prevent the front ends 5252 of the two guide protrusions 525 from moving away from each other and deforming after the contact part 511 repeatedly hits the stop protrusion 523. Furthermore, the side of the contact portion 511 facing the opening 522 is spherically shaped, that is, the contact portion 511 contacts the first collision member 41 through the spherical part, to prevent the drum 21 from getting stuck due to excessive rotational resistance.

[0065] Regarding the structure of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, in some embodiments, the positions of the first sound-generating mechanism 4 and the second sound-generating mechanism 5 can be interchanged, that is, the first sound-generating mechanism 4 is set on the roller 21, and the second sound-generating mechanism 5 is set on the inner wall of the receiving cavity 100.

[0066] Regarding the structure of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, in some embodiments, as shown in the appendix... Figure 8As shown, the first mounting member 42 is a metal ring, the first collision member 41 is a metal spring formed on the metal ring, so that the first collision member 41 can undergo elastic deformation, and the second collision member 51 is a protrusion structure fixed on the drum 21.

[0067] In some embodiments, the housing 1 includes an upper cover 11 and a lower cover 12, which are detachably connected, and a receiving cavity 100 is formed between the upper cover 11 and the lower cover 12. For example, the upper cover 11 and the lower cover 12 are connected at the edges by a snap-fit ​​structure for easy disassembly and maintenance.

[0068] Among them, as attached Figure 2 and 4 As shown, a central post 122 is provided on the lower cover 12. The central post 122 passes through the drum 21 and the spring 22 is connected to the central post 122. Specifically, the central post 122 and the lower cover 12 are detachably connected. A first circuit board 6 is fixedly mounted on the drum 21. A first electrical connector 61 is provided on the first circuit board 6. The first end 31 of the connecting wire 3 is electrically connected to the first electrical connector 61. A second circuit board 7 is mounted on one side of the receiving cavity 100 on the lower cover 12. A second electrical connector 71 is provided on the second circuit board 7, which is arranged around the winding mechanism 2. Specifically, the second electrical connector 71 is an annular copper sheet. An external electrical terminal 72 is also installed on the second circuit board 7, which is electrically connected to the second electrical connector 71. The first electrical connector 61 and the second electrical connector 71 abut against each other and are electrically connected, thereby completing the electrical connection between the first electrical connector 61 and the external electrical terminal 72. The external electrical terminal 72 is a conductive copper sheet on which wires, power banks, charging heads, and other devices can be soldered and connected, so that the cable reel can also be used as an extension of a power bank or as an extension of a charging head.

[0069] Furthermore, the lower cover 12 has several connection ports 121, with the electrical external terminal 72 protruding from one of the connection ports 121. The manufacturer can adjust the mounting angle of the second circuit board 7 according to the actual product type required, so that the electrical external terminal 72 protrudes from the desired connection port 121, facilitating installation for corresponding product types. Alternatively, a covering layer can be applied to the outside of the outer casing 1 to prevent the second circuit board 7 from being exposed from the connection port 121.

[0070] Regarding the positional design of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, in some embodiments, please refer to the appendix. Figure 2 , 4 11, 12, the first collision member 41 is fixedly mounted on the lower cover 12, and the second collision member 51 is mounted on the first circuit board 6. The first sound-generating mechanism 4 can be integrally mounted with the lower cover 12 or independently mounted on the lower cover 12, for example, attached... Figure 2As shown, the entire first sound-generating mechanism 4 is integrally integrated into the lower cover 12. The second impact member 51 is mounted to the edge of the first circuit board 6. In these embodiments, the connecting plate 524 of the second mounting member 52 is the first circuit board 6 itself.

[0071] Regarding the positional design of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, see the appendix for details in some other embodiments. Figure 3 , 4 In step 10, the first sound-generating mechanism 4 is mounted on the upper cover 11, and the second sound-generating mechanism 5 is mounted on the side of the winding mechanism 2 away from the first circuit board 6. The first sound-generating mechanism 4 can be integrally formed with the upper cover 11 or independently of it, for example, attached to... Figure 10 As shown, a cavity communicating with the receiving cavity 100 is formed at the upper cover 11. The thickness of this cavity is the same as the thickness of the first mounting member 42. The annular first mounting member 42 is embedded into the cavity with an interference fit and can be fixed with adhesive. The second mounting member 52 of the second sound-generating mechanism 5 is fixed to the drum 21 by bolts or integral molding. In these embodiments, the connecting plate 524 of the second mounting member 52 is disposed opposite to the first circuit board 6 and is respectively disposed on both sides of the drum 21.

[0072] Regarding the positional design of the first sound-generating mechanism 4 and the second sound-generating mechanism 5, see the appendix in some embodiments. Figure 2 , 3 10, 11, 12. Two of each of the first sound-generating mechanism 4 and the second sound-generating mechanism 5 are provided. One of the first sound-generating mechanisms 4 is fixedly installed on the lower cover 12, and the other first sound-generating mechanism 4 is fixedly installed on the upper cover 11. The second collision member 51 corresponding to one of the second sound-generating mechanisms 5 is fixedly installed on the first circuit board 6, and the second collision member 51 of the other second sound-generating mechanism 5 is fixedly installed on the drum 21.

[0073] In some embodiments, a magnetic component can be used to reset the first colliding member 41 and the second colliding member 51 after collision. For example, a magnetic component can replace the aforementioned elastic part 512, and the contact part 511 can be an iron ball. The magnetic component is disposed on the connecting plate 524. When the contact part 511 collides with the first colliding member 41 and moves into the movable groove 521, the magnetic force of the magnetic component causes the iron ball to reset and re-extend from the opening 522. This embodiment is not shown in the accompanying drawings.

[0074] In addition, the cable reel can be equipped with a locking mechanism, which can be used in conjunction with the center post 122 or the lower cover 12 to lock the current state of the drum 21 and prevent the connecting cable 3 from retracting naturally. For example, the locking mechanism can adopt a compression structure design, where the locking mechanism and the lower cover work together to press and fix the drum; or, the locking mechanism can adopt any other circumferential locking structure, such as the locking structure of a measuring tape. It should be noted that this locking mechanism is not shown in the attached drawings.

[0075] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
