[0024] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1 to 7 shown in a kind of wire hiding structure, including shell 1, the shell 1 is equipped with the first passageway 3 for the one end of wire 2 to enter, the second passageway 4 for the other end of wire 2 to enter, and the receiving space 5 between the first passageway 3 and the second passageway 4, the receiving space 5 is equipped with limit end 6, when the wire 2 is moved out or enters the first passageway 3 or the second passageway 4, the limit end 6 is used to keep the wire 2 bending and being located in the receiving space 5.

[0026] In the expansion deformation process of traditional earphone, built-in wire is forced to be pulled due to length limitation, and welding point also bears huge stress, so that wire breakage, insulation layer damage or welding point falling off and other problems easily occur, which greatly shortens the service life of wire. The utility model provides buffer space for wire by the cooperation of receiving space and limit end, when different components of earphone expand or bend and deform, wire located in receiving space can adaptively move in the first passageway or the second passageway, so that the problem of welding point pulling or wire breakage is reduced, when the deformation of earphone causes the length change of wire, wire can bend or contract in receiving space, direct excessive stretching is avoided, and the limit end restricts the bending shape of wire, ensures that wire cannot excessively displace, greatly reduces the pulling of welding point, makes the built-in activity of wire not have length restriction, so that the physical integrity of wire can be maintained, and the service life is prolonged. When the elastic component of earphone restores, wire becomes bending state from contraction state again under the limitation of limit end.

[0027] Furthermore, as a preferred embodiment of this utility model and not a limitation, in the prior art, in order to deal with the problems that may occur when the wire expands or bends, it is often necessary to reserve a large amount of redundant wire length. This undoubtedly occupies the internal space of the headphones and is also prone to tangling or squeezing between the wires, creating fault points. This utility model, by setting up a storage space, can restrict the movement path of the wire. Under the premise of ensuring the safety of the wire and reducing pulling, it can control the required wire length, reduce unnecessary space occupation, and make the headphones more likely to be designed towards miniaturization and lightweight while realizing the complex wire hiding function, thus meeting the market demand for portable headphones.

[0028] Optionally, in some embodiments, the storage space is located between the neckband 7 of the earphone and the earpiece. When the neckband expands and deforms, the wires inside the neckband need more wire length to adapt to the expansion path of the neckband. The wires of the neckband can drive the wires in the storage space to move closer to the neckband. At this time, the wires switch from a bent storage state to a bent contraction state. When the neckband resets, the expansion path of the neckband is restored and shortened. The wires inside the neckband need to shorten their wire length to adapt to the neckband. The wires are synchronously reset under the drive of the limiting end, so that the wires can be stored in the storage space and switch from a bent contraction state to a bent storage state.

[0029] Optionally, in some embodiments, the storage space is located between the neckband 7 and the microphone stem 8 of the earphone. Similarly, when the neckband expands and deforms, it can drive the cable to move closer to the neckband. When the neckband returns to its original position, the cable returns to its original position simultaneously under the drive of the limiting end, allowing the cable to be stored in the storage space. When the microphone stem bends and deforms, the cable inside the microphone stem needs more cable length to adapt to the bending path of the microphone stem. The cable of the microphone stem can drive the cable in the storage space to move closer to the microphone stem. At this time, the cable switches from a bent storage state to a bent contraction state. When the microphone stem returns to its original position, the bending path of the microphone stem is restored and shortened. The cable inside the microphone stem needs to shorten its cable length to adapt to the microphone stem. The cable returns to its original position simultaneously under the drive of the limiting end, allowing the cable to be stored in the storage space and switch back from a bent contraction state to a bent storage state.

[0030] like Figures 1 to 7 The diagram shows a cable concealment structure, wherein the storage space 5 is provided with an arc-shaped inner wall 51 that abuts against the cable 2, and the limiting end 6 is disposed between the arc-shaped inner wall 51 and the first channel 3, and / or, the limiting end 6 is disposed between the arc-shaped inner wall 51 and the second channel 4.

[0031] Furthermore, as a preferred embodiment of this utility model and not a limitation, the arc-shaped inner wall within the storage space abuts against the cable, providing additional support for the cable. When the earphone deforms, the cable closely conforms to the arc-shaped inner wall during bending, dispersing the pressure on the cable and preventing stress concentration at a single point that could damage it. The arc-shaped design better conforms to the bending curvature of the cable, reducing friction between the cable and the inner wall of the storage space through sliding, lowering the risk of insulation wear, and further protecting the physical properties of the cable.

[0032] Specifically, the limiting end is set between the arc-shaped inner wall and the first channel, or between the arc-shaped inner wall and the second channel. This can limit the bending area when the wire passes through the first or second channel. By working together with the arc-shaped inner wall, the movement of the wire is restricted within the buffer zone of the storage space, minimizing unnecessary displacement of the wire during deformation. This prevents the wire from being unable to return to its original position after leaving the storage space and reduces the pulling on the solder joints, thus extending the service life of the wire.

[0033] In addition, compared with traditional right-angle or flat inner walls, the curved inner wall design can provide a larger contact area and more reasonable bending space for the cable within the same volume, so that the storage space can be fully utilized. Without increasing the overall size of the headphones, it can accommodate more cables of varying lengths, optimize the layout of the cable hiding structure, and help to make the internal structure of the headphones more compact.

[0034] like Figures 3 to 7 The diagram shows a wire-hiding structure, wherein the arc-shaped inner wall 51 includes a first arc-shaped inner wall 511 disposed opposite to the first channel 3, and the limiting end 6 includes a first limiting end 61 disposed between the first arc-shaped inner wall 511 and the second channel 4.

[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, since the first arc-shaped inner wall is arranged opposite to the first channel, when the wire enters from the first channel, it can naturally bend along the curvature of the first arc-shaped inner wall, providing guidance for the wire to enter the storage space, avoiding the wire from being bent into a dead angle due to loss of direction at the entrance or scratching other components, and greatly reducing the risk of wire damage.

[0036] Specifically, the first limiting end, located between the first arc-shaped inner wall and the second channel, controls the path of the cable as it passes through the storage space and into the second channel. This ensures that the cable exits the storage space at a predetermined, optimized bending angle and position, preventing excessive stretching or twisting of the cable, effectively protecting its integrity and guaranteeing stable operation of the headphones.

[0037] In addition, the first arc-shaped inner wall makes full use of the space between the first channel and the second channel. By conforming to the natural bending characteristics of the cable, it achieves smooth cable storage with minimal space occupation, making more efficient use of the limited space inside the headphones and reserving more layout space for other components, which helps to make the overall structure of the headphones smaller and lighter.

[0038] Furthermore, due to the control of the cable's exit path by the first limiting end, even if the headphones undergo repeated expansion and deformation during frequent use, such as the violent shaking of the headphones during running or jumping by sports enthusiasts, the cable can always move stably within the range defined by the first arc-shaped inner wall and the first limiting end, ensuring the continuity and stability of signal transmission. This effectively reduces problems such as audio signal interruption or distortion caused by loose or displaced cables, greatly enhancing the reliability of the headphones and thus improving the user experience.

[0039] like Figures 3 to 7 The diagram shows a wire-hiding structure, wherein the arc-shaped inner wall 51 includes a second arc-shaped inner wall 512 disposed opposite to the second channel 4, and the limiting end 6 includes a second limiting end 62 disposed between the second arc-shaped inner wall 512 and the first channel 3.

[0040] Furthermore, as a preferred embodiment of this utility model and not a limitation, the second arc-shaped inner wall is arranged opposite to the second channel, providing a bending support for the wire passing through the second channel. When the wire enters the storage space from the second channel, it can smoothly enter the storage space along the second arc-shaped inner wall, avoiding wire wear or excessive bending caused by poor entry angle. By cooperating with the first arc-shaped inner wall, it achieves all-round guidance for the wire to enter the storage space from different directions, greatly reducing the probability of wire damage.

[0041] Specifically, the second limiting end, located between the second arc-shaped inner wall and the first channel, controls the path of the cable as it folds back from the storage space and passes through the first channel. It complements the first limiting end, providing a corresponding limiting effect regardless of whether the cable moves forward or backward, ensuring that the cable follows a preset angle and position when it passes through, preventing stretching or twisting caused by improper passing through, protecting the integrity of the cable in all aspects, and ensuring stable operation of the headphones.

[0042] In addition, the second arc-shaped inner wall can adapt to the direction of the wires, making the storage space layout more balanced and symmetrical without increasing the overall volume, further improving the space utilization efficiency and achieving a compact and reasonable structural design.

[0043] like Figure 3The diagram shows a wire-concealing structure, wherein the storage space 5 is provided with a first straight inner wall 521 located between the first channel 3 and the first arc-shaped inner wall 511, and a second straight inner wall 522 located between the second channel 4 and the second arc-shaped inner wall 512.

[0044] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first straight inner wall is located between the first channel and the first arc-shaped inner wall. When the wire enters from the first channel, it provides a straight guide for the wire, thereby ensuring that the wire can move smoothly along the first straight inner wall before entering the first arc-shaped inner wall, avoiding the wire from becoming scattered, tangled or excessively bent immediately after exiting the channel, and reducing the risk of damage to the starting section of the wire.

[0045] Furthermore, the second straight inner wall is located between the second channel and the second arc-shaped inner wall, and plays a guiding role for the wire entering from the second channel, so that the wire can transition to the second arc-shaped inner wall in an orderly manner, ensuring the smoothness of the wire entering process.

[0046] Specifically, the first straight inner wall works in conjunction with the first curved inner wall. When the cable enters the storage space, the first straight inner wall assists the cable in moving steadily forward, while the first curved inner wall provides cushioning and protection, making the cable storage process smoother and improving space utilization. Furthermore, the second straight inner wall works in conjunction with the second curved inner wall to achieve symmetrical spatial partitioning for the inserted cable. This ensures that regardless of whether the cable moves forward or backward, it can be managed evenly on both sides of the storage space, avoiding various problems caused by the cable running around haphazardly within the storage space.

[0047] Specifically, during the frequent expansion and deformation of the headphones, the first and second straight inner walls provide additional support points for the cable. For example, when the headphones are subjected to lateral compression, causing the cable to tend to shift within the storage space, the first and second straight inner walls can hold the cable in place, preventing excessive displacement. Together with the first and second curved inner walls and the limiting end, they form a stable three-dimensional support system, ensuring that the cable remains firmly within the storage space under complex stress conditions, thus guaranteeing the stability of the headphone's audio transmission.

[0048] like Figure 3 The above describes a wire-hiding structure. The first limiting end 61 is V-shaped and protrudes towards the second arc-shaped inner wall 512. The first limiting end 61 has a first arc-shaped limiting end 611 near the first arc-shaped inner wall 511 and a first straight limiting end 612 near the second channel 4.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation, the V-shaped first limiting end provides multi-dimensional constraints on the wire. The design convex towards the second arc-shaped inner wall effectively restricts both lateral displacement and longitudinal offset towards the second arc-shaped inner wall as the wire passes through the storage space into the second channel. The first arc-shaped limiting end, close to the first arc-shaped inner wall, precisely holds the wire, preventing it from slipping off the path due to excessive movement in the bending area. This ensures the wire moves along a predetermined trajectory conforming to the arc-shaped inner wall, guaranteeing the stability of the wire at the bending point.

[0050] Specifically, the first straight limiting end is close to the second channel and plays a calibration role for the wires passing through the second channel. It ensures that the wires enter the second channel in a straight and stable state, avoiding the wires from being crooked or tangled in the second channel, and avoiding various faults caused by the wires not passing through smoothly.

[0051] Furthermore, as a preferred embodiment of this utility model and not a limitation, when the first limiting end of the V-shaped structure contacts the wire, it can disperse the tensile force on the wire. When the earphone expands and deforms, and the wire is subjected to an outward pulling force, the first arc-shaped limiting end and the first straight limiting end each bear a portion of the force. Compared with the traditional single limiting structure, this greatly reduces the stress concentration on the wire in a localized area, reduces the risk of the wire breaking due to uneven stress, and extends the service life of the wire.

[0052] Specifically, the first limiting end utilizes the irregular space between the first arc-shaped inner wall and the second channel. The V-shaped design can flexibly adjust the limiting angle according to the width of this area, which not only makes full use of the limiting function, but also does not occupy too much unnecessary space, making the layout around the storage space more compact and reasonable. This helps to optimize the overall internal structure of the headphones and integrate more functions within a limited space.

[0053] Optionally, in order to improve the continuity of the storage space, the first arc-shaped limiting end 611 is connected to the first arc-shaped inner wall 511, and the first straight limiting end 612 is connected to the second channel 4.

[0054] like Figure 3 The diagram shows a wire-hiding structure in which the second limiting end 62 is V-shaped and protrudes toward the first arc-shaped inner wall 511. The second limiting end 62 has a second arc-shaped limiting end 621 near the second arc-shaped inner wall 512 and a second straight limiting end 622 near the first channel 3.

[0055] Furthermore, as a preferred embodiment of this utility model and not a limitation, the second limiting end, which is V-shaped and protrudes towards the inner wall of the first arc, forms a symmetrical layout with the first limiting end. This provides multi-dimensional constraint on the wire from opposite directions. When the wire passes through the storage space into the first channel, the second limiting end can restrict the wire's lateral displacement or longitudinal offset towards the inner wall of the first arc. The second arc-shaped limiting end is close to the inner wall of the second arc, closely conforming to the bending path of the wire, ensuring a stable transition of the wire in the reverse bending area, preventing it from deviating from its trajectory, and guaranteeing the stability of the wire at key bending points.

[0056] Specifically, the second straight limiting end is close to the first channel to ensure that the wire passes through smoothly in a regular and straight state, avoiding problems such as tangling and skewing at the exit, preventing various faults caused by abnormal wire passing through, and working together with the first straight limiting end to achieve control over the bidirectional passing through of the wire.

[0057] Furthermore, the second limiting end of the V-shaped structure, when in contact with the cable, works in conjunction with the first limiting end to efficiently disperse tensile force. When the headphones face expansion deformation in different directions, causing the cable to be subjected to tensile force, the second arc-shaped limiting end and the second straight limiting end of the V-shape each bear a portion of the force, preventing the cable from bearing excessive stress locally. Together with the first limiting end, they comprehensively reduce stress concentration in the cable, greatly reducing the risk of cable breakage, further extending its service life, and ensuring the continuity of audio transmission in the headphones under various operating conditions.

[0058] Furthermore, the second limiting end can adapt to the spatial characteristics between the second arc-shaped inner wall and the first channel. The V-shaped design can adapt to the outline of the storage space, thereby flexibly adjusting the limiting angle and making full use of the limiting function without wasting space, making the layout on the other side of the storage space more compact and reasonable.

[0059] Optionally, in order to improve the continuity of the storage space, the second arc-shaped limiting end 621 is connected to the second arc-shaped inner wall 512, and the second straight limiting end 622 is connected to the first channel 3.

[0060] like Figures 1 to 7 The diagram shows a wire-concealing structure in which the first channel 3 and the second channel 4 are staggered and opposite to each other, and the storage space 5 is symmetrically arranged.

[0061] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the staggered arrangement of the first and second channels prevents the cable from being pulled and moved in a straight line, and also creates a symmetrical layout of the cable inside the earphone. When the earphone undergoes expansion and deformation, regardless of the direction of the external force applied, the tensile force on both ends of the cable can be more evenly distributed throughout the cable-concealing structure. For example, in sports scenarios where the user's head moves rapidly, the symmetrical channel design prevents the cable from experiencing excessive force on one side and relative slack on the other, effectively avoiding cable damage caused by uneven force and greatly extending the cable's lifespan.

[0062] Specifically, the symmetrical storage space provides a stable and symmetrical buffer area for the cable during bending and storage. Regardless of whether the cable enters or exits from the first or second channel, it can receive equal protection in the corresponding symmetrical storage space, ensuring that the force on each part of the cable is coordinated and consistent, and reducing stress concentration points.

[0063] Furthermore, the staggered arrangement of the first and second channels, along with the symmetrical design of the storage space, allows for more efficient use of the limited internal space of the headphones, avoiding wasted space or a cluttered layout. Compared to an asymmetrical design, it allows for more rational planning of cable routing, storage location, and spacing with other components within the same volume, reserving neat and ample installation space for other critical components such as batteries and circuit boards, resulting in a compact and sophisticated structural design for the headphones.

[0064] Furthermore, when installing cables, the symmetry of the channels and storage spaces allows workers to easily follow a standardized operating procedure to thread the cables through the corresponding channels and accurately place them in the symmetrical storage spaces, greatly shortening the assembly time.

[0065] like Figures 1 to 7 The diagram shows a cable concealment structure in which the first channel 3, the storage space 5, and the second channel 4 are arranged in an S-shape, and the cable 2 is arranged in an S-shape in the storage space.

[0066] Furthermore, as a preferred embodiment of this utility model and not a limitation, the S-shaped layout can make full use of the originally irregular or difficult-to-use narrow space inside the headphones. Compared with straight or simply curved channel and storage space designs, it can conform to the internal contour of the headphones, further placing the wires in the limited space area, freeing up more regular arrangement space for other components, and achieving a compact and optimized internal structure of the headphones.

[0067] Specifically, the cable is arranged in an S-shape within the storage space, ensuring efficient use of its length. This avoids both excessively long cables that lead to clutter and tangles, and cables that are too short to accommodate headphone expansion or bending deformation, achieving organized storage and efficient use of the cable within a limited space. When the headphones experience expansion or deformation, the S-shaped cable layout distributes stress gradually. Under external force, the cable does not bear a sudden, large tensile force at a single point or section, but rather distributes the force evenly across multiple bends and segments along the S-curve. This gradual dissipation of impact and tensile forces from different directions avoids stress concentration, significantly reducing the risk of cable breakage and extending its lifespan.

[0068] Furthermore, the S-shaped enclosure formed by the first channel, the storage space, and the second channel provides a stable support structure for the cable. As the cable moves within the S-shaped channel, each bend and segment is constrained and buffered by the inner wall of the enclosure structure, preventing the cable from slipping out of its path due to excessive shaking or displacement, thus further ensuring the integrity of the cable under complex stress environments.

[0069] Furthermore, the S-shaped layout effectively controls the position and direction of the cable, reducing noise and interference caused by the cable, ensuring that the headphones can work stably, maintain good acoustic performance, and bring users a clearer and more realistic listening experience.

[0070] like Figures 1 to 7 The earphone shown includes the wire-concealing structure described above.

[0071] This invention provides a buffer space for the cable by combining the storage space with the limiting end. When different parts of the earphone expand or bend, the cable located in the storage space can move adaptively in the first or second channel, thereby reducing the problem of solder joint pulling or cable breakage. The cable's internal movement is not restricted by length, thus extending the cable's service life.

[0072] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the cable concealment structure of this utility model can provide all-round protection for the internal cable of the earphone, avoiding frequent pulling, squeezing and bumping of the internal cable. The S-shaped channel and storage space layout in the cable concealment structure, together with the arc-shaped inner wall and limiting end, can effectively disperse stress and prevent the cable from being damaged due to uneven force or excessive pulling, greatly extending the overall service life of the earphone and reducing the need for frequent replacement due to cable problems.

[0073] Furthermore, as a preferred embodiment of this utility model and not a limitation, the concealed wiring structure makes efficient use of the internal space of the earphone, allowing for a reasonable layout of internal components without increasing the overall size of the earphone. This not only helps to achieve a miniaturized and lightweight design of the earphone, meeting users' pursuit of portability, but also makes the earphone appearance more exquisite and beautiful, enhancing the product's appeal in terms of appearance design. This allows the earphone to combine aesthetics and portability, satisfying users' experience needs.

[0074] Example 1

[0075] like Figures 1 to 7 The cable concealment structure shown includes a housing 1. The housing 1 has a first channel 3 for one end of the cable 2 to pass through, a second channel 4 for the other end of the cable 2 to pass through, and a storage space 5 located between the first channel 3 and the second channel 4. The storage space 5 has a limiting end 6. When the cable 2 moves out of or into the first channel 3 or the second channel 4, the limiting end 6 is used to keep the cable 2 bent and disposed in the storage space 5.

[0076] This invention provides a buffer space for the cable 2 by combining the storage space 5 with the limiting end 6. When different parts of the earphone expand or bend and deform, the cable 2 located in the storage space 5 can move adaptively in the first channel 3 or the second channel 4, thereby reducing the problem of solder joint pulling or cable 2 breakage. This allows the cable 2 to move freely without length constraints, thus extending the service life of the cable 2.

[0077] The storage space 5 is located between the neckband 7 and the earpiece. When the neckband expands and deforms, the wire 2 inside the neckband needs more wire length to adapt to the expansion path of the neckband. The wire 2 of the neckband can drive the wire 2 in the storage space 5 to move closer to the neckband. At this time, the wire 2 switches from a bent storage state to a bent contraction state. When the neckband resets, the expansion path of the neckband is restored and shortened. The wire 2 inside the neckband needs to shorten its length to adapt to the neckband. The wire 2 is synchronously reset under the drive of the limiting end 6, so that the wire 2 can be stored in the storage space 5 and switch from a bent contraction state to a bent storage state.

[0078] Example 2

[0079] The difference between Example 2 and Example 1 is as follows:

[0080] The storage space is located between the neckband 7 and the microphone stem 8 of the headphones. When the neckband expands and deforms, the wire 2 inside the neckband needs more wire length to adapt to the expansion path of the neckband. The wire 2 of the neckband can drive the wire 2 in the storage space 5 to move closer to the neckband. At this time, the wire 2 switches from a bent storage state to a bent contraction state. When the neckband resets, the expansion path of the neckband is restored and shortened. The wire 2 inside the neckband needs to shorten its length to adapt to the neckband. The wire 2 is synchronously reset under the drive of the limiting end 6, so that the wire 2 can be stored in the storage space 5 and switch back from a bent contraction state to a bent storage state.

[0081] When the microphone boom bends and deforms, the wire 2 inside the microphone boom needs more wire 2 length to adapt to the bending path of the microphone boom. The wire 2 of the microphone boom can drive the wire 2 in the storage space 5 to move closer to the microphone boom. At this time, the wire 2 switches from the bent storage state to the bent contraction state. When the microphone boom returns to its original position, the bending path of the microphone boom is restored and shortened. The wire 2 inside the microphone boom needs to shorten its wire 2 length to adapt to the microphone boom. The wire 2 is synchronously restored under the drive of the limiting end 6, so that the wire 2 can be stored in the storage space 5 and switch from the bent contraction state to the bent storage state to restore its original position.

[0082] Example 3

[0083] Based on Example 1, Example 3 also has the following implementation method:

[0084] The storage space 5 is provided with an arc-shaped inner wall 51 that abuts against the wire 2, and the limiting end 6 is disposed between the arc-shaped inner wall 51 and the first channel 3.

[0085] Example 4

[0086] The difference between Example 4 and Example 3 is as follows:

[0087] The limiting end 6 is located between the arc-shaped inner wall 51 and the second channel 4.

[0112] Example 13

[0113] Example 13, based on the above examples, also has the following implementation method:

[0114] The headphones include the cable concealment structure described above.

[0115] This invention provides a buffer space for the cable 2 by combining the storage space 5 with the limiting end 6. When different parts of the earphone expand or bend and deform, the cable 2 located in the storage space 5 can move adaptively in the first channel 3 or the second channel 4, thereby reducing the problem of solder joint pulling or cable 2 breakage. This allows the cable 2 to move freely without length constraints, thus extending the service life of the cable 2.

[0116] Specifically, in some embodiments, the concealed wire structure of this utility model can provide all-round protection for the wire 2 inside the earphone, avoiding frequent pulling, squeezing and bumping of the wire inside the earphone. The concealed wire structure utilizes the layout of the first channel 3, the second channel 4 and the storage space 5, and is equipped with the limiting end 6, which can effectively disperse stress and prevent the wire 2 from being damaged due to uneven force or excessive pulling, greatly extending the overall service life of the earphone and reducing the need for frequent replacement due to wire problems.

[0117] Furthermore, as a preferred embodiment of this utility model and not a limitation, the concealed wiring structure makes efficient use of the internal space of the earphone, allowing for a reasonable layout of internal components without increasing the overall size of the earphone. This not only helps to achieve a miniaturized and lightweight design of the earphone, meeting users' pursuit of portability, but also makes the earphone appearance more exquisite and beautiful, enhancing the product's appeal in terms of appearance design. This allows the earphone to combine aesthetics and portability, satisfying users' experience needs.

[0118] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
