Description

Technical Field

[0001] This utility model relates to the field of cable storage technology, and in particular to a telescopic cable assembly and charging device. Background Technology

[0002] As people's demands for quality of life increase, products using retractable cords are becoming increasingly common in people's daily lives, such as chargers, clotheslines, and tow ropes. Retractable cords have a telescopic function, allowing people to choose to pull the cord out to the appropriate length when needed, and to store the cord inside the housing when not in use, preventing the cord from taking up space and affecting storage when not in use.

[0003] When users pull the retractable cord outwards, they cannot observe the internal condition of the product and do not know whether the retractable cord can continue to be pulled outwards. If the retractable cord is pulled out to its maximum length, continuing to pull the retractable cord outwards may damage the product. Utility Model Content

[0004] In view of this, the present invention provides a retractable cable module and a charging device to solve the problem that existing retractable cables may be damaged during the outward pulling process.

[0005] On the one hand, this application provides a telescopic cable module, including a housing, a reel rotatably mounted in the housing, a telescopic cable wound in the reel, and a sound-generating component located in the housing, the sound-generating component including an impact member and a sound-generating member, the impact member and the sound-generating member being located on the same side of the telescopic cable; The impact member is movable relative to the sound-generating member, and at least a portion of the impact member is located on the exit path of the telescopic line, so that the telescopic line can drive the impact member to impact the sound-generating member during the exit process.

[0006] On the other hand, this application also provides a charging device, including a charging module and a telescopic cable module as described above, wherein the charging module is located inside the housing and is electrically connected to the telescopic cable.

[0007] Beneficial effects: Since one end of the impactor is located on the exit path of the telescopic cable, the telescopic cable will come into contact with the impactor during the outward pulling process. The friction during relative movement generates a thrust on the impactor, causing it to move closer to the sound-emitting component. The collision between the impactor and the sound-emitting component will produce a sound. When the telescopic cable is pulled out to its maximum extension length, it stops moving outward, the thrust on the impactor disappears, and the impactor stops colliding with the sound-emitting component, thus stopping the sound emission. This serves as a reminder to the user that the telescopic cable should not be pulled outward any further. The user can judge whether the telescopic cable can still be pulled outward by the sound produced by the collision between the impactor and the sound-emitting component, which can reduce the risk of the telescopic cable module being damaged during the outward pulling process.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0012] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0013] Please see Figures 1 to 4 An embodiment of this utility model provides a telescopic cable module 10, including a housing 12, a winding reel 14 rotatably installed inside the housing 12, and a telescopic cable 16 connected to the winding reel 14. The telescopic cable 16 can be wound on the winding reel 14. When needed, the telescopic cable 16 is pulled outward. When the telescopic cable 16 moves outward, it drives the winding reel 14 to rotate in the cable output direction. After the tension on the telescopic cable 16 disappears, when the winding reel 14 rotates in the opposite direction, i.e. the cable retraction direction, it can drive the telescopic cable 16 to retract and rewind onto the winding reel 14.

[0014] The retractable cord module 10 can be used in electronic products such as chargers or power banks, in which case the retractable cord 16 is a wire. Alternatively, the retractable cord module 10 can also be used in everyday items such as clotheslines or tow ropes, in which case the retractable cord 16 is a rope. The following description uses the retractable cord module 10 used in charging device 100 as an example.

[0015] The charging device 100 includes a retractable cable module 10 and a charging module 18. The charging module 18 is located inside the housing 12. The retractable cable 16 is a conductor, with one end electrically connected to the charging module 18 and the other end extending outside the housing 12 to connect to electronic devices such as mobile phones, thereby charging the electronic devices. The charging device 100 can be a portable power bank with its own power supply, or a charger with a plug that requires an external power source.

[0016] The housing 12 has an internal mounting plate 20, on which the telescopic cable module 10 and the charging module 18 are respectively mounted on opposite sides. Along the thickness direction of the charging device 100, the mounting plate 20 is fixed in the middle of the housing 12, thereby dividing the internal space of the housing 12 into two cavities. The telescopic cable module 10 is installed in one cavity, and the charging module 18 is installed in the other cavity.

[0017] A convex shaft is provided on one side of the mounting plate 20. The reel 14 of the telescopic cable module 10 is movably sleeved on the outside of the convex shaft, allowing the reel 14 to rotate around the convex shaft, thereby rotatably mounting the reel 14 inside the housing 12. The telescopic cable module 10 also includes an elastic element, such as a coil spring. One end of the elastic element is connected to the reel 14, and the other end is connected to the convex shaft. When the telescopic cable 16 moves outward, causing the reel 14 to rotate around the convex shaft, the elastic element will deform. After the telescopic cable 16 is released, the elastic element returns to its original shape under its own elastic force, and drives the reel 14 to rotate in the opposite direction, thereby causing the telescopic cable 16 to move into the housing 12 and rewind onto the reel 14. The elastic element achieves the effect of automatic cable winding.

[0018] In one embodiment, a sound-generating assembly 22 is provided inside the housing 12. The sound-generating assembly 22 includes an impact member 24 and a sound-generating member 26, which are located on the same side of the telescopic cable 16. The impact member 24 is movable relative to the sound-generating member 26, and at least a portion of the impact member 24 is located on the exit path of the telescopic cable 16. Therefore, when the telescopic cable 16 is pulled outward, the friction between the telescopic cable 16 and the impact member 24 during relative movement generates a thrust on the impact member 24, allowing the impact member 24 to strike the sound-generating member 26, thereby emitting sound.

[0019] The statement that at least a portion of the impact member 24 is located on the exit path of the telescopic line 16 means that a portion of the impact member 24 is located on the exit path of the telescopic line 16, or that all of the impact member 24 is located on the exit path of the telescopic line 16, without limitation.

[0020] Optionally, one end of the impact member 24 is fixed relative to the housing 12, while the other end is movable relative to the sound-emitting member 26. The other end of the impact member 24 is also in contact with the retractable cord 16 in its retracted state. Therefore, during the outward extension of the retractable cord 16, the friction between the retractable cord 16 and the impact member 24 generates a thrust, driving the impact member 24 to strike the sound-emitting member 26, thus producing sound. When the retractable cord 16 is extended to its maximum length, it stops moving outward, the thrust on the impact member 24 disappears, and the impact member 24 stops striking the sound-emitting member 26, ceasing to emit sound. This serves as a reminder to the user that the retractable cord 16 has been extended to its maximum length and should not be pulled outward any further. During the process of pulling the telescopic cable 16 outward, the user can judge whether the telescopic cable 16 can still be pulled outward by the sound emitted by the collision between the impact member 24 and the sound-emitting member 26, thus avoiding the risk of damage to the telescopic cable module 10 caused by continuing to pull the telescopic cable 16 outward after it has been pulled out to its maximum extension length.

[0021] Furthermore, one end of the impact member 24 is fixed relative to the housing 12, and the other end of the impact member 24 can form a free end, so that it can impact the sound-generating member 26 under the drive of the telescopic line to produce sound.

[0022] Optionally, both the impact element 24 and the sound-emitting element 26 are metal parts that produce a sound upon impact. In an optional example, the sound-emitting element 26 is a bell, which can produce a louder sound when struck, in order to better alert the user through sound.

[0023] The outline of the reel 14 is roughly circular, the outline of the mounting plate 20 is roughly square, and the size of the mounting plate 20 is larger than that of the reel 14. The reel 14 is rotatably mounted in the middle position of the mounting plate 20. The four corners of the mounting plate 20 protrude from the outside of the reel 14, and the sound-generating component 22 is mounted on one corner of the mounting plate 20.

[0024] The impact member 24 is elastic and can move relative to the sound-generating member 26 through deformation. During its movement towards the sound-generating member 26, the impact member 24 deforms and generates elastic force. After colliding with the sound-generating member 26, the impact member 24, under the action of its own elastic force and the impact force, moves away from the sound-generating member 26, achieving a reset effect. It then re-engages with the outward-moving telescopic line 16, which again exerts a pushing force on the impact member 24, ultimately causing it to move back towards the sound-generating member 26 and impact it again. This repeated impact during the cable extension process continuously generates sound. The impact continues until the telescopic line 16 is pulled out to its maximum extension length, at which point it stops moving outward, and the impact member 24 ceases impacting the sound-generating member 26.

[0025] It should be noted that the thrust of the telescopic cable 16 on the impact member 24 can be a force that pushes the impact member 24 toward the sound-generating member 26, in which case the impact member 24 is located behind the sound-generating member 26 in the cable exit direction. Alternatively, the thrust of the telescopic cable 16 on the impact member 24 can also be a force that pushes the impact member 24 away from the sound-generating member 26. Under the action of the thrust, the impact member 24 deforms and generates elasticity, and under the action of its own elasticity, moves toward the sound-generating member 26, in which case the impact member 24 is located in front of the sound-generating member 26 in the cable exit direction. In an optional example, the impact member 24 is located in front of the sound-generating member 26 in the cable exit direction, that is, the impact member 24 is closer to the cable outlet 42 on the housing 12 than the sound-generating member 26.

[0026] The impact element 24 and the sound-emitting element 26 are located on the side of the telescopic cable 16 facing away from the reel 14. This prevents the impact element 24 and the sound-emitting element 26 from affecting the telescopic cable 16 winding on the reel 14. Furthermore, when the user pulls the telescopic cable 16 outward, the plug of the telescopic cable 16 is often pulled away from the user, which is more in line with the ergonomic force exertion habit. During the outward movement, the telescopic cable 16 tends to deviate away from the reel 14, making it easier for the telescopic cable 16 to contact the impact element 24 and drive the impact element 24 to move.

[0027] In an alternative example, when the retractable cord 16 is in the retracted state, the retractable cord 16 includes a main body and an extension. The main body is wound on the reel 14 and has a spiral structure and is attached to each other in sequence. The extension extends from the main body to the outside of the housing 12 to connect with the electronic product. The extension is not attached to the main body. The impact member 24 and the sound-emitting member 26 are located on the side of the extension facing away from the reel 14.

[0028] The impact member 24 includes a first elastic connecting portion 28 and a first impact portion 30. The first impact portion 30 is connected to one end of the first elastic connecting portion 28 near the telescopic cable 16, and a portion of the first impact portion 30 is located on the outgoing path of the telescopic cable 16. The first elastic connecting portion 28 has a certain elasticity and can deform to make the first impact portion 30 move relative to the sound-emitting member 26, that is, to make the first impact portion 30 move closer to or away from the sound-emitting member 26. During the outward movement of the telescopic cable 16, it will come into contact with the first impact portion 30 and generate a thrust on the first impact portion 30, causing the first impact portion 30 to move relative to the sound-emitting member 26 and deforming the first elastic connecting portion 28. Under the elastic force of the first elastic connecting portion 28, the first impact portion 30 moves towards the sound-emitting member 26 and finally collides with the sound-emitting member 26 to produce sound. After the sound-emitting component 26 collides with the first impact part 30, the first impact part 30 moves away from the sound-emitting component 26 under the action of impact force and elastic force. The first elastic connecting part 28 deforms away from the sound-emitting component 26. After the first impact part 30 re-contacts the telescopic line 16, it continues to move away from the sound-emitting component 26 under the action of the telescopic line 16, increasing the deformation of the first elastic connecting part 28. Under the action of the elastic force of the first elastic connecting part 28, the first impact part 30 moves again towards the sound-emitting component 26 and collides with the sound-emitting component 26.

[0029] The volume of the first impact part 30 is smaller than the volume of the sound-emitting element 26, which facilitates the impact of the first impact part 30 on the sound-emitting element 26 and reduces the accuracy requirements for the movement trajectory of the first impact part 30. Optionally, the volume of the sound-emitting element 26 is 1.5 to 4 times the volume of the first impact part 30, which facilitates the impact of the first impact part 30 on the sound-emitting element 26 while avoiding the sound-emitting element 26 being too large and occupying too much space in the housing 12.

[0030] In an alternative embodiment, the first impact part 30 is a small metal ball, and the first elastic connection part 28 is a spring.

[0031] The housing 12 has a stop 32 inside. The stop 32 and the impact member 24 are located on the same side of the telescopic line 16, and the stop 32 is located on the side of the impact member 24 facing away from the sound-emitting member 26. When the first impact member 30 collides with the sound-emitting member 26 and moves away from the sound-emitting member 26, the first impact member 30 will collide with the stop 32. The stop 32 forms an impact force on the first impact member 30, causing it to move towards the sound-emitting member 26. Under the action of the impact force and the elastic force, the first impact member 30 moves towards the sound-emitting member 26, ensuring that the first impact member 30 can collide with the sound-emitting member 26.

[0032] The structure of the stop member 32 is similar to that of the impact member 24. The stop member 32 includes a second elastic connecting part 34 and a second impact part 36. The second impact part 36 is connected to the side of the second elastic connecting part 34 near the telescopic line 16. The first impact part 30 is located between the sound-emitting member 26 and the second impact part 36. The second elastic connecting part 34 is elastic, allowing the second impact part 36 to move relative to the first impact part 30. After the first impact part 30 collides with the second impact part 36, the first impact part 30 moves towards the sound-emitting member 26 under the impact force of the second impact part 36 and the elastic force of the first elastic connecting part 28, while the second impact part 36 moves away from the sound-emitting member 26. At this time, the second elastic connecting part 34 deforms in the direction away from the sound-emitting member 26 and generates an elastic force on the second impact part 36, causing it to move towards the sound-emitting member 26. When the first impact part 30 collides with the sound-emitting element 26, the first impact part 30 moves away from the sound-emitting element 26 and collides with the second impact part 36 moving towards the sound-emitting element 26, causing the first impact part 30 to move towards the sound-emitting element 26 again.

[0033] In an alternative example, the second impact portion 36 is a small metal ball, and the second elastic connection portion 34 is a spring.

[0034] The housing 12 has a fixed post 38 inside, and the impact member 24 and the stop member 32 are both fixed to the fixed post 38. That is, the end of the first elastic connecting part 28 away from the first impact part 30 and the end of the second elastic connecting part 34 away from the second impact part 36 are respectively connected to the fixed post 38. In this way, the first impact part 30 and the second impact part 36 are suspended in the air, preventing the first impact part 30 and the second impact part 36 from being affected by friction caused by contact with other components such as the housing or mounting plate.

[0035] Optionally, one end of the fixing post 38 is fixed to the mounting plate 20. Along the axial direction of the fixing post 38, the first elastic connecting part 28 and the second elastic connecting part 34 are connected to the middle position of the fixing post 38 and are at the same height, so that the first impact part 30 and the second impact part 36 are spaced apart from the mounting plate 20 and the housing 12, forming a suspended state.

[0036] The housing 12 contains a first positioning member 40, which is located on opposite sides of the telescopic cord 16, along with the impact member 24. The first positioning member 40 limits the telescopic cord 16, preventing it from shifting away from the impact member 24 during its outward movement, thus preventing the cord from contacting the impact member 24 and consequently preventing the impact member 24 from colliding with the sound-generating member 26. Optionally, the first positioning member 40 is located between the main body and the extension of the telescopic cord 16, i.e., the extension of the telescopic cord 16 is located between the first positioning member 40 and the impact member 24. The first positioning member 40 prevents the telescopic cord 16 from shifting towards the winding reel 14 during its outward movement, ensuring that the cord 16 contacts the impact member 24 and drives the impact member 24 to move.

[0037] The housing 12 has an outlet 42 for the telescopic cable 16 to pass through. Inside the housing 12 are two second positioning members 44, located between the first positioning member 40 and the outlet 42. The two second positioning members 44 are spaced apart and positioned on opposite sides of the telescopic cable 16. A cable outlet groove is formed between the two second positioning members 44. The width of the cable outlet groove is equal to or slightly larger than the width of the telescopic cable 16, thus limiting the telescopic cable 16 and preventing it from deviating from the preset cable outlet path during its outward movement, ensuring that the telescopic cable 16 can contact the impact member 24 during its outward movement.

[0038] In an optional example, the first positioning element 40 and the second positioning element 44 are both positioning posts, and the first positioning element 40 and the two second positioning elements 44 are all disposed on the mounting plate 20.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
