Description

Technical Field

[0001] The utility model belongs to the technical field of earphone wires, and particularly relates to an earphone wire with an automatic rewinding structure. Background Art

[0002] Headphones are an important audio device, mainly composed of a sound generating unit, a headband or earplug part, connecting wires and various control components. Headphones come in a variety of types, including over-ear, in-ear, earbud and ear-hook types. Over-ear headphones are comfortable to wear, have a relatively large sound generating unit, and can present excellent sound quality and strong bass effects; in-ear headphones are small and portable, and have good sound insulation when inserted deep into the ear canal; earbud headphones are lightweight and affordable; ear-hook headphones are suitable for use during sports and are not easy to fall off. Headphones are widely used in scenarios such as music appreciation, movie watching, gaming, voice calls and language learning. Using headphones in public places can avoid disturbing others and allow users to immerse themselves in their own audio world. With the development of technology, headphones are constantly adding new functions, such as noise reduction, wireless connection and touch operation, bringing more convenient and high-quality audio experiences to users;

[0003] Currently, there are usually no connecting wires on the commercially available Bluetooth headphones, and they are connected to the user's ears in a hanging manner. However, in this way, when the user is doing sports, such as running, due to certain vibrations, the Bluetooth headphones are likely to fall off and be damaged, causing certain difficulties in carrying the Bluetooth headphones. On the other hand, when the Bluetooth headphones are being charged, an additional charging cable often needs to be carried, which is inconvenient to use;

[0004] Chinese Patent with the publication number of "CN207926860U" discloses a portable Bluetooth headphone, which includes a charging cable and a Bluetooth headphone. The Bluetooth headphone is detachably connected to the charging cable. The charging cable includes a headphone connecting wire, a power connecting wire and a sectional block. The headphone connecting wire is fixedly connected to the sectional block and electrically connected to the sectional block. The power connecting wire is detachably connected to the sectional block. When the power connecting wire is connected to the sectional block, the power connecting wire is electrically connected to the sectional block. The charging cable is provided with a first magnetic charging head, and the Bluetooth headphone is provided with a first magnetic charging port. The first magnetic charging port and the first magnetic charging head are matched. In the utility model, when the user has special needs, the Bluetooth headphone can be connected to the charging cable and the power connecting wire can be removed, so that the Bluetooth headphone can be restricted by the headphone connecting wire and the sectional block, with good convenience and reduced risk of the Bluetooth headphone falling off and being damaged;

[0005] During the use of the above-mentioned earphones, there are obvious defects in the wire part. Due to the lack of a winding structure, during the process of wearing the earphones, the entire wire will drag on the user's neck. On the one hand, during exercise, it is very easy to accidentally pull and damage the wire. For example, during activities such as running and fitness, the large movements of the body are very likely to accidentally pull the wire, thereby damaging the conductors inside the wire and affecting the normal use of the earphones. On the other hand, the wire dragging is also prone to entanglement. Whether during daily activities or when storing and putting away, the wire may be entangled with other items, bringing great inconvenience to the user. At the same time, the swinging of the wire at the neck will also cause certain discomfort to the user, and this discomfort may distract the user's attention and affect the use experience. In summary, it can be seen that the earphones have certain defects and deficiencies during the overall use process, so it is urgent to improve them. Summary of the Invention

[0006] Aiming at the problems mentioned in the background technology, the purpose of the present utility model is to provide an earphone wire with an automatic winding structure to solve the problems proposed in the background technology.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0008] An earphone wire with an automatic winding structure includes a power plug. The top of the power plug is fixedly connected with a main wire. The upper end of the main wire is fixedly connected with a control switch. The top of the main wire is fixedly connected with two branch wires. The tops of the two branch wires are fixedly connected with earphone bodies respectively. The outer surfaces of the branch wires and the outer surface of the main wire are both movably installed with winding mechanisms. The outside of the winding mechanism is fixedly connected with a limiting mechanism. The winding mechanism is used for winding the main wire and the branch wires, and the limiting mechanism is used for positioning the main wire and the branch wires.

[0009] The winding mechanism includes a housing. The top and bottom of the housing are both provided with wire grooves. The main wire and the branch wires pass through the two wire grooves and penetrate the housing. An elastic winding element is fixedly installed inside the housing. The main wire and the branch wires are respectively wound around the outer surfaces of the elastic winding elements in the corresponding housings.

[0010] As a preferred technical solution, the elastic winding element includes a torsion spring. The torsion spring is fixedly connected to both ends inside the housing. The inner side of the torsion spring is fixedly connected with a winding wheel. A wire passing hole is opened in the middle of the winding wheel. The main wire and the branch wires respectively penetrate the corresponding wire passing holes and are wound around the outer surface of the winding wheel.

[0011] As a preferred technical solution, both ends of the winding wheel are fixedly connected with support shafts. The outer ends of the support shafts penetrate the housing and are rotatably connected with the housing.

[0012] As a preferred technical solution, an anti-slip sleeve is fixedly connected to the outer surface of the power connection plug, and anti-slip strip grooves are equidistantly formed on the outer surface of the anti-slip sleeve.

[0013] As a preferred technical solution, the limiting mechanism includes a guide rail fixedly installed on the outer side of the housing. A lead screw is rotatably connected inside the guide rail. The thread directions at both ends of the lead screw are opposite. Sliders are threadedly connected to both ends of the lead screw. Limiting arms are fixedly connected to the top and bottom of the sliders. The inner sides of the outer ends of the limiting arms are respectively in fitting connection with the corresponding main wire and branch wire. One end of the lead screw penetrates through the guide rail.

[0014] As a preferred technical solution, one end of the lead screw penetrates through the guide rail and is fixedly connected with an adjustment knob handle. Anti-slip protrusions are equidistantly fixedly connected to the outer surface of the adjustment knob handle.

[0015] As a preferred technical solution, a clamping groove is formed at the outer end of the limiting arm. The top view shape of the clamping groove is V-shaped. An anti-slip rubber pad is provided inside the clamping groove. The inner wall of the clamping groove is in fitting connection with the outer sides of the corresponding main wire and branch wire.

[0016] In summary, the present utility model mainly has the following beneficial effects:

[0017] First, the present device is provided with a winding mechanism. When wearing the earphone, pulling the branch wire and the main wire will cause the winding wheel to rotate and tighten the torsion spring. After wearing is completed, the compressed torsion spring resets to drive the winding wheel to rotate, winding the main wire and the branch wire. During use, the torsion spring can adaptively provide a winding force, avoiding the dragging and tangling of the wires and discomfort in the neck, and facilitating carrying. Whether in use or carrying, this mechanism can maximize the convenience. The winding mechanism makes the wire management of the earphone more orderly, bringing a comfortable use experience to the user, and effectively solving the problem of messy wires of traditional earphones;

[0018] Second, the device is also provided with a limiting mechanism. If the user feels discomfort in the ear caused by the reset pulling of the torsion spring, the main wire and the branch wire can be pulled to an appropriate length, and the adjustment knob handle is rotated to make the lead screw rotate, driving the slider to drive the limiting arm to displace. The clamping groove of the limiting arm fits the wire. The V-shaped clamping groove increases the contact area, and the rubber anti-slip pad improves the friction force, thereby positioning the wire. This enables the wire to be flexibly adjusted according to the user's needs, further improving the use convenience. The limiting mechanism provides a personalized use experience for the user, meets the requirements for the length of the earphone wire in different scenarios, and enhances the practicality of the earphone.

Detailed implementation manners

[0024] Embodiment

[0025] Refer to Figures 1 to 4 , an earphone wire with an automatic winding structure in this embodiment includes a power plug 1, the top of the power plug 1 is fixedly connected with a main wire 2, the upper end of the main wire 2 is fixedly connected with a control switch 3, the top of the main wire 2 is fixedly connected with two branch wires 4, the tops of the two branch wires 4 are both fixedly connected with an earphone body 5, the outer surfaces of the branch wires 4 and the outer surface of the main wire 2 are both movably installed with a winding mechanism 6, the outside of the winding mechanism 6 is fixedly connected with a limiting mechanism 7, the winding mechanism 6 is used for winding the main wire 2 and the branch wires 4, and the limiting mechanism 7 is used for positioning the main wire 2 and the branch wires 4;

[0026] The winding mechanism 6 includes a housing 61, wire grooves 62 are opened at the top and bottom of the housing 61, the main wire 2 and the branch wires 4 pass through the housing 61 through the two wire grooves 62, an elastic winding element 63 is fixedly installed inside the housing 61, the main wire 2 and the branch wires 4 are respectively wound around the outer surfaces of the elastic winding element 63 in the corresponding housing 61, the power plug 1 is connected to the main wire 2, and the main wire 2 is connected to the two branch wires 4 through the control switch 3 to the earphone body 5. The overall structure is clear and reasonable. The wire grooves 62 are opened in the housing 61 of the winding mechanism 6 to facilitate the passing of the main wire 2 and the branch wires 4. The internal elastic winding element 63 can wind the main wire 2 and the branch wires 4. During use, it can effectively avoid the dragging and winding of the wires, prevent the wires from being accidentally pulled and damaged during movement, and also reduce the discomfort brought to the user by the swinging of the wires, maximizing the convenience of use. At the same time, when carrying, the main wire 2 and the branch wires 4 can be automatically retracted, facilitating storage. The limiting mechanism 7 can position the main wire 2 and the branch wires 4 to meet different usage requirements, further improving the convenience and practicality of the wire.

[0027] Refer to Figures 2 - 3, the elastic winding element 63 includes a torsion spring 631. The torsion spring 631 is fixedly connected to both ends inside the housing 61. A winding wheel 632 is fixedly connected to the inner side of the torsion spring 631. A wire threading hole 633 is formed in the middle of the winding wheel 632. The main wire 2 and the branch wire 4 respectively pass through the corresponding wire threading holes 633 and are wound around the outer surface of the winding wheel 632. Both ends of the winding wheel 632 are fixedly connected with support shafts 634. The outer ends of the support shafts 634 penetrate through the housing 61 and are rotatably connected to the housing 61. The torsion spring 631 is fixed at both ends inside the housing 61 to provide a power source for winding. When the main wire 2 and the branch wire 4 are pulled, the winding wheel 632 is driven to rotate, compressing the torsion spring 631. After use, the compressed torsion spring 631 attempts to reset, driving the winding wheel 632 to rotate to rewind the main wire 2 and the branch wire 4. The wire threading holes 633 in the middle of the winding wheel 632 enable the main wire 2 and the branch wire 4 to be stably wound around its outer surface. The support shafts 634 at both ends are rotatably connected to the housing 61, ensuring the smoothness of the winding process. This design can effectively avoid the situation of wire dragging, entanglement, and being pulled and damaged, reduce the discomfort caused to the user's neck, improve the convenience and comfort of use, and is also convenient to carry, enhancing the practicality of the earphone wire.

[0028] Reference Figure 1 , an anti-slip sleeve 8 is fixedly connected to the outer surface of the power connection plug 1. Anti-slip groove strips are equidistantly arranged on the outer surface of the anti-slip sleeve 8. The anti-slip sleeve 8 fixedly connected to the outer surface of the power connection plug 1 improves the use experience. When inserting or removing the power connection plug 1, the anti-slip sleeve 8 can increase the friction between the hand and the plug, making the operation more stable and not easy to slip off. Whether it is in a relatively hasty situation or when inserting or removing the plug in a narrow space, the anti-slip sleeve 8 can effectively improve the accuracy and efficiency of the operation. At the same time, the equidistantly arranged anti-slip groove strips further enhance the anti-slip effect and also add a certain aesthetic feeling and recognition on the appearance, making the earphone wire more practical and distinctive.

[0029] Reference Figure 1 , Figure 2 and Figure 4, the limiting mechanism 7 includes a guide rail 71 which is fixedly installed on the outer side of the housing 61. A lead screw 72 is rotatably connected inside the guide rail 71. The thread directions at both ends of the lead screw 72 are opposite. Both ends of the lead screw 72 are threadedly connected with sliders 73. Limiting arms 74 are fixedly connected to the top and bottom of the slider 73. The inner sides of the outer ends of the limiting arms 74 are respectively in fit connection with the corresponding main wire 2 and branch wire 4. One end of the lead screw 72 penetrates through the guide rail 71 and is fixedly connected with an adjustment knob handle 75. Anti-slip protrusions are fixedly connected to the outer surface of the adjustment knob handle 75 at equal intervals. A clamping groove 76 is formed at the outer end of the limiting arm 74. The top view shape of the clamping groove 76 is arranged in a V shape. An anti-slip rubber pad is provided inside the clamping groove 76. The inner wall of the clamping groove 76 is in fit connection with the outer sides of the corresponding main wire 2 and branch wire 4. The guide rail 71 is fixed to the outer side of the housing 61, providing stable support for the internal lead screw 72 and slider 73. The thread directions at both ends of the lead screw 72 are opposite. When rotated, the two sliders 73 can be driven to slide synchronously, thereby driving the displacement of the limiting arms 74. The clamping groove 76 at the outer end of the limiting arm 74 is in a V shape, which can increase the contact area with the main wire 2 and branch wire 4. The anti-slip rubber pad inside further improves the friction force, enabling precise positioning of the main wire 2 and branch wire 4 after being pulled. The anti-slip protrusions on the outer surface of the adjustment knob handle 75 facilitate user operation. By rotating the adjustment knob handle 75, the position of the limiting arm 74 can be easily adjusted. This design enables the wires to be flexibly adjusted according to the specific needs of the user, greatly improving the convenience and practicality of use.

[0030] Principle of use and advantages: By setting up the winding mechanism 6, the device demonstrates excellent performance during use. During the wearing process of the earphone body 5, when the user pulls the branch wire 4 and the main wire 2, the branch wire 4 and the main wire 2 will pull the winding wheel 632, causing the winding wheel 632 to rotate. While the winding wheel 632 rotates, the torsion spring 631 will be tightened. When the earphone body 5 is worn out, since the torsion spring 631 is in a compressed state, it will attempt to reset, thereby driving the winding wheel 632 to rotate. The rotation of the winding wheel 632 can rewind the main wire 2 and the branch wire 4. Since the earphone is being worn, when the winding wheel 632 rotates, as much as possible of the excess parts of the main wire 2 and the branch wire 4 can be wound up. During the user's use, due to the presence of the torsion spring 631, a winding force can be adaptively provided at any time, enabling the branch wire 4 and the main wire 2 to have an automatic winding function. In this way, the phenomenon of the wires being dragged and wound or sticking to the user's neck causing discomfort can be avoided, maximizing the convenience of use. At the same time, during carrying, the main wire 2 and the branch wire 4 can also be automatically retracted, greatly facilitating carrying.

[0031] By setting the limit mechanism 7, the device can exert powerful functions during use. If the user feels discomfort caused by the torsion spring 631 resetting and pulling the main wire 2 and the branch wire 4 to traction the ear during use, the main wire 2 and the branch wire 4 can be pulled to an appropriate length for use. At this time, by turning the adjustment knob 75, since the adjustment knob 75 is connected to the lead screw 72, the adjustment knob 75 can drive the lead screw 72 to rotate inside the guide rail 71. Since the thread directions at both ends of the lead screw 72 are different, the two sliders 73 can be synchronously driven to slide as the lead screw 72 rotates. By the sliding of the sliders 73, the limit arms 74 can be assisted to displace relative to each other. At this time, the clamping groove 76 at the outer end of the limit arm 74 fits against the outer surface of the wire. The clamping groove 76 is V-shaped, which can increase its contact area with the main wire 2 and the branch wire 4. A rubber anti-slip pad is provided inside the clamping groove 76, and the anti-slip pad can further increase the friction force. At this time, the pulled main wire 2 and branch wire 4 can be positioned. It can be seen that this wire can be flexibly adjusted according to the specific needs of the user during use, which can further improve the convenience of use of this wire.
