Technical Field

[0001] This application relates to the field of locking structure technology, and more particularly to an earphone case. Background Technology

[0002] With the development of technology, Bluetooth headsets have become widely used in various fields such as personal entertainment, communication, and smart device connectivity due to their convenient wireless connection, good sound quality, multi-device compatibility, and compact portability. They allow users to enjoy music, watch videos, make voice calls and video conferences anytime, anywhere, and can also connect to smart home devices and gaming equipment, greatly enhancing the user experience and convenience of life.

[0003] In conventional Bluetooth headset designs, the connection between the earphone case and the lid typically relies on a complex hinge structure. While this structure allows for manual rotation to open the lid, its manufacturing process involves assembling multiple precision components, which not only increases manufacturing costs but also reduces production efficiency. Utility Model Content

[0004] This application provides an earphone case to address the problem that the connection between the conventional earphone case body and the cover usually relies on a complex hinge structure, the production process of which involves the assembly of multiple precision parts, which not only increases manufacturing costs but also leads to reduced production efficiency.

[0005] In a first aspect, embodiments of this application provide an earphone case, including: Box body; A lid, which is rotatably mounted on the box body; A locking assembly having a locking tongue that is slidably disposed on the housing, one end of the locking tongue elastically abutting against the housing so that the other end of the locking tongue abuts against the housing; An elastic fitting component, one end of which is connected to the cover and the other end of which is connected to the box body, and a locking channel is provided between the elastic fitting component and the cover; When the cover rotates, the elastic fitting abuts against the locking tongue and slides to lock or release the locking channel, thereby closing or opening the cover.

[0006] Optionally, the earphone case has a pivot, the two ends of which are connected to the case body. The cover is rotatably mounted on the pivot. The elastic fitting has an elastic segment, which is sleeved on the pivot. After the cover is closed, the elastic force of the elastic segment is less than the force of the locking tongue locking the locking channel.

[0007] Optionally, the elastic fitting has a fitting section connected to the elastic segment, one end of the fitting section away from the elastic segment is connected to the cover, and the fitting section and the cover enclose to form the locking channel.

[0008] Optionally, the box body has a limiting groove and a receiving groove, the elastic section is located within the limiting groove, and after the cover is closed, the mating section is able to be located within the receiving groove.

[0009] Optionally, one side of the latch has a first guide surface, which is set at an acute angle to the sliding direction of the latch. When the cover is closed, the elastic fitting can abut against the first guide surface to retract the latch.

[0010] Optionally, the latch has a second guide surface on the side facing away from the first guide surface. The second guide surface is set at an acute angle to the sliding direction of the latch. When the cover is opened, the elastic fitting can abut against the second guide surface to retract the latch.

[0011] Optionally, the locking assembly further includes an elastic element, the two ends of which elastically abut against the housing and the locking tongue, respectively.

[0012] Optionally, the box body is provided with a first guide groove, the locking tongue is slidably disposed in the first guide groove, and the two ends of the elastic element along the sliding direction of the locking tongue respectively abut against the side wall of the first guide groove and the locking tongue.

[0014] Optionally, a first limiting hole is provided on the side wall of the first guide groove that abuts against the elastic member, and a second limiting hole is provided on one end of the locking tongue near the elastic member, with the two ends of the elastic member respectively receiving and limiting the first limiting hole and the second limiting hole.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: The housing of this application is used to house the earphone body, and the cover is rotatably mounted on the housing via an elastic fitting. One end of the elastic fitting is connected to the cover, and the other end is connected to the housing, providing elastic support for the rotation of the cover. The locking component has a locking tongue. The locking tongue is slidably mounted on the housing, with one end of the locking tongue elastically abutting against the housing, causing the other end of the locking tongue to abut against the housing. A locking channel is provided between the elastic fitting and the cover. When the cover rotates, the elastic fitting abuts against the sliding locking tongue, and the locking tongue locks or releases the locking channel under the action of elastic force, thereby realizing the closing or opening of the cover. When the cover is closed, the elastic fitting pushes the locking tongue to slide, and the locking tongue enters the locking channel, locking the cover onto the housing; when the cover is opened, the elastic fitting pushes the locking tongue to slide again, and the locking tongue exits from the locking channel, and the cover springs open under the action of the elastic fitting. By adopting the design of the locking component and the elastic fitting, the traditional complex hinge structure is replaced, reducing the use of precision parts, simplifying the production process, and reducing manufacturing costs. The simplified structure makes the production process more efficient, reduces assembly time and error rate, and improves production efficiency. Attached Figure Description

[0024] To address the issue that the connection between the conventional headphone case 1 and the cover 2 typically relies on a complex hinge structure, the production process of which involves the assembly of multiple precision components. This not only increases manufacturing costs but also leads to reduced production efficiency. This application provides a headphone case that replaces the traditional complex hinge structure by employing a locking component 3 and an elastic mating part 4, thereby reducing the use of precision components, simplifying the production process, and lowering manufacturing costs.

[0025] Please see Figures 1 to 4 This application provides an earphone case including a case body 1, a cover 2, a locking component 3, and an elastic fitting component 4. The case body 1 is used to hold the earphone body 6. The cover 2 is rotatably disposed on the case body 1. The locking component has a locking tongue 31, which is slidably disposed on the case body 1. One end of the locking tongue 31 elastically abuts against the case body 1, so that the other end of the locking tongue 31 abuts against the case body 1. One end of the elastic fitting component 4 is connected to the cover 2, and the other end of the elastic fitting component 4 is connected to the case body 1. A locking channel 4a is provided between the elastic fitting component 4 and the cover 2. When the cover 2 rotates, the elastic fitting component 4 abuts against the locking tongue 31 and slides, so that the locking tongue 31 locks or releases the locking channel 4a, thereby closing or opening the cover 2.

[0026] In the embodiments of this application, the earphone case 1 is made of high-strength polycarbonate (PC) material, which has good impact resistance and durability. The case 1 is generally used to hold the earphone body 6. The cover 2 is rotatably mounted on the case 1 via an elastic fitting 4. The elastic fitting 4 is made of fatigue-resistant stainless steel or other metal material with a certain elasticity. One end of the elastic fitting 4 is connected to the cover 2, and the other end is connected to the case 1. The locking component 3 includes a locking tongue 31, which is made of stainless steel or other metal material with a certain elasticity. It can be a separate metal block that works with other elastic components to achieve an elastic connection with the case 1, or it can be a combination of elastic and rigid locking functions, such as an integrally formed elastic segment and rigid locking segment. The locking tongue 31 is slidably mounted on the case 1, and one end of the locking tongue 31 elastically abuts against the case 1.

[0027] A locking channel 4a is provided between the elastic fitting 4 and the cover 2. When the cover 2 rotates, the elastic fitting 4 slides against the locking tongue 31. The locking tongue 31 locks or releases the locking channel 4a under the action of the elastic member 32, thereby realizing the closing or opening of the cover 2. When the cover 2 is closed, the elastic fitting 4 pushes the locking tongue 31 to slide, and the locking tongue 31 enters the locking channel 4a, locking the cover 2 onto the box 1. When the cover 2 is opened, the elastic fitting 4 pushes the locking tongue 31 to slide again, and the locking tongue 31 exits from the locking channel 4a. The cover 2 springs open under the action of the elastic fitting 4. The elastic fitting 4 can be set as a torsion spring or spring with an extension structure. The elastic fit between the box 1 and the cover 2 is achieved by the torsion spring or spring. The locking channel 4a is formed by the extension structure on the torsion spring or spring and the cover 2. In this embodiment, the specific shape of the extension structure is not limited. It can be an arc shape, a rectangle, or a single rod-shaped structure. It is only necessary that after the elastic fitting 4 connects the box 1 and the cover 2, it can form a channel between it and the cover 2 to lock the locking tongue 31. At the same time, the shape and position of the locking channel 4a are not limited. They can be determined according to the enclosure between the elastic fitting 4 and the cover 2.

[0028] It should be noted that this application, by employing a locking component 3 and an elastic mating part 4, replaces the traditional complex hinge structure, reducing the use of precision components, simplifying the production process, and lowering manufacturing costs. Traditional hinge structures may require multiple metal parts and complex assembly processes, while this design only requires a simple locking tongue 31, greatly simplifying the production process. The selected materials, such as polycarbonate, silicone, and aluminum alloy, not only ensure the durability and reliability of the headphone case but also reduce the overall weight, improving the product's portability. Furthermore, due to the simplified structure, the production process is more efficient, reducing assembly time and error rates, improving production efficiency, and lowering the risk of headphone case damage due to component failure, further enhancing product reliability and lifespan.

[0029] Please see Figure 2 , Figure 3 as well as Figure 9 To ensure greater stability when the elastic fitting 4 generates elastic force and to prevent the cover 2 from being accidentally opened after it is closed due to the action of the elastic fitting 4, the earphone case has a rotating shaft 5. The two ends of the rotating shaft 5 are connected to the case body 1. The cover 2 is rotatably mounted on the rotating shaft 5. The elastic fitting 4 has an elastic segment 41, which is fitted onto the rotating shaft 5. After the cover 2 is closed, the elastic force of the elastic segment 41 is less than the force of the locking tongue 31 locking the locking channel 4a.

[0030] In one embodiment of this application, the cover 2 is rotatably mounted on the box body 1 via a pivot 5. Both ends of the pivot 5 are connected to the box body 1 to ensure smooth rotation of the cover 2. The elastic fitting 4 is made of fatigue-resistant stainless steel or other metal material. The elastic fitting 4 has an elastic segment 41, which is generally an elastic structure such as a torsion spring. The elastic segment 41 is fitted onto the pivot 5. Specifically, after the cover 2 is closed, the elastic force of the elastic segment 41 is less than the force required by the locking tongue 31 to lock the locking channel 4a, thereby preventing the cover 2 from being accidentally opened. For example, the elastic segment 41 can be made of spring steel torsion spring, which has good elasticity and fatigue resistance, ensuring stable elasticity even after long-term use.

[0031] This application significantly improves the stability and reliability of the opening and closing of the cover 2 by incorporating a hinge 5 and an elastic segment 41 of the elastic fitting 4 within the headphone case. The elastic segment 41, fitted onto the hinge 5, makes the elastic fitting 4 more stable when generating elastic force. When using the headphone case, the elastic fitting 4 generates a certain opening force, requiring only a certain amount of force on the cover 2 to disengage the locking tongue 31 from the locking space. The elastic force of the elastic fitting 4 assists in the subsequent opening process. By designing the elastic force of the elastic segment 41 to be less than the force required for the locking tongue 31 to lock the locking channel 4a, it ensures that the cover 2 will not be accidentally opened due to the action of the elastic fitting 4 after it is closed, further enhancing the stability and safety of the headphone case. Compared to traditional designs, this structure not only simplifies the production process and reduces manufacturing costs but also improves product durability and user experience. For example, in actual use, when the user closes the cover 2, the elastic force of the elastic segment 41 is insufficient to overcome the locking force between the locking tongue 31 and the case 1, thus ensuring that the cover 2 is firmly locked and will not be accidentally opened due to accidental collision or vibration, extending the service life of the headphone case and improving the overall quality of the product.

[0032] Please see Figure 4In order to enable the locking channel 4a to adapt to the locking of the locking tongue 31, the structure of the elastic fitting 4 is specially designed. The elastic fitting 4 has a fitting section 42 connected to the elastic section 41. The end of the fitting section 42 away from the elastic section 41 is connected to the cover 2. The fitting section 42 and the cover 2 enclose each other to form the locking channel 4a.

[0033] In the embodiments of this application, the elastic segment 41 can be made of spring steel or other materials with high elasticity and fatigue resistance, while the mating segment 42 can be made of the same material as the elastic segment 41. The shape and size of the locking channel 4a are designed according to the shape and size of the latch 31 to ensure that the latch 31 can smoothly enter and lock within the locking channel 4a. For example, the locking channel 4a can be designed as a rectangular through hole, the size of which matches the size of the latch 31. When the cover 2 is closed, the mating segment 42 of the elastic mating member 4 pushes the latch 31 to slide, allowing the latch 31 to enter the locking channel 4a and achieve locking; when the cover 2 is opened, the mating segment 42 pushes the latch 31 to slide again, allowing the latch 31 to exit from the locking channel 4a and releasing the cover 2.

[0034] This application utilizes a specially designed structure for the elastic mating component 4, enabling the locking channel 4a to better adapt to the locking tongue 31, thereby improving the locking reliability and stability of the headphone case. The combined design of the elastic segment 41 and the mating segment 42 not only ensures the stability of the elastic mating component 4 when generating elastic force, but also, through the precise design of the locking channel 4a, guarantees that the locking tongue 31 can accurately enter and exit the locking channel 4a. This design avoids locking failures or misoperations caused by mismatch between the locking channel 4a and the locking tongue 31, significantly improving the user experience. Furthermore, the use of high-strength materials to manufacture the elastic mating component 4 further enhances its durability and reliability. For example, in actual use, when the user closes the cover 2, the locking tongue 31 can accurately enter the locking channel 4a and lock securely, preventing accidental loosening or opening due to external force; when opening the cover 2, the locking tongue 31 can smoothly exit the locking channel 4a, ensuring that the cover 2 can open smoothly, thus improving the overall performance and lifespan of the headphone case.

[0035] Please see Figure 2 , Figure 3 , Figure 7 as well as Figure 8 To prevent the elastic mating part 4 from shifting position during long-term use or from failing to connect when it is hit, and to facilitate the locking of the locking channel 4a by the locking tongue 31, the box body 1 is provided with a limiting groove 1a and a receiving groove 1b. The elastic section 41 is contained in the limiting groove 1a, and after the cover 2 is closed, the mating section 42 can be contained in the receiving groove 1b.

[0036] In one embodiment, the shape and size of the limiting groove 1a match the elastic segment 41, ensuring that the elastic segment 41 can be stably compressed and released within the limiting groove 1a, while preventing its displacement in the lateral or longitudinal direction. The limiting groove 1a can be designed as a long strip-shaped groove, with its length direction aligned with the compression direction of the elastic segment 41. The width and depth are adjusted according to the size of the elastic segment 41 to ensure that the elastic segment 41 can be freely compressed and released within the limiting groove 1a without unnecessary displacement. In actual assembly, the elastic segment 41 is first placed within the limiting groove 1a, and then the cover 2 is mounted on the housing 1 via the pivot 5, ensuring that the elastic segment 41 can function normally within the limiting groove 1a. This design not only improves the stability of the elastic mating part 4 but also enhances its reliability during use. The design of the limiting groove 1a effectively prevents the elastic segment 41 from shifting position during long-term use, especially after impact or frequent use, and it can still maintain its normal function. This design not only extends the service life of the elastic mating part 4 but also improves the overall durability of the headphone case and the user experience. In actual use, even if the earphone case is subjected to accidental impact or frequent use over a long period of time, the elastic segment 41 will not shift from its predetermined position, thereby ensuring that the opening and closing function of the cover 2 is always normal.

[0037] In the embodiments of this application, the shape and size of the receiving groove 1b match the mating section 42, ensuring that the mating section 42 can accurately embed into the receiving groove 1b when the cover 2 is closed, thereby providing a stable locking position for the latch 31. The receiving groove 1b can be designed as a rectangular or circular groove, the depth and width of which are adjusted according to the size of the mating section 42. In actual assembly, the mating section 42 is guided into the receiving groove 1b when the cover 2 is closed, ensuring that the latch 31 can smoothly enter the locking channel 4a and achieve locking. This design, through precise structural fit, improves the alignment accuracy between the latch 31 and the locking channel 4a, thereby ensuring the reliability and stability of the locking process.

[0038] It should be noted that this application, by creating a receiving groove 1b on the housing 1, provides a stable limiting space for the mating section 42 of the elastic mating part 4, significantly improving the locking accuracy and reliability of the locking tongue 31 in the locking channel 4a. This design not only ensures that the locking tongue 31 can accurately enter the locking channel 4a when the cover 2 is closed, avoiding locking failure due to inaccurate alignment, but also enhances the overall structural stability of the headphone case. For example, in actual use, even under frequent use or slight impact, the mating section 42 can still stably embed itself in the receiving groove 1b, ensuring that the locking tongue 31 can lock smoothly. This design simplifies the assembly process, reduces production costs, and improves production efficiency. Through precise structural design, the performance and reliability of the headphone case are significantly improved, further enhancing the product's market competitiveness.

[0039] Please see Figures 2 to 5 In order to enable the elastic fitting 4 to retract the latch 31 and lock the locking space during the process of closing the cover 2, the latch 31 has a first guide surface 311 on one side. The first guide surface 311 is set at an acute angle to the movement direction of the latch 31. When the cover 2 is closed, the elastic fitting 4 can abut against the first guide surface 311 to retract the latch 31.

[0040] In one embodiment, one side of the latch 31 can be understood as the side of the latch 31 close to the elastic mating member 4 when the cover 2 is open. When the cover 2 begins to close, the mating section 42 of the elastic mating member 4 gradually approaches the first guide surface 311 of the latch 31. Since the first guide surface 311 and the movement direction of the latch 31 are set at an acute angle α, the contact between the elastic mating member 4 and the first guide surface 311 will generate an inward component force, pushing the latch 31 to retract towards the elastic member 32. As the cover 2 closes further, the latch 31 continues to retract under the pressure of the elastic mating member 4. When it reaches the closed position, the elastic member 32 pushes the latch 31 out and into the locking channel 4a, thus achieving locking. For example, the first guide surface 311 can be designed as a slope with an angle of approximately 15° to 45° to ensure that the latch 31 can be smoothly pushed back when the cover 2 is closed. The latch 31 can be made of high-strength plastic or aluminum alloy to ensure its durability in long-term use. The elastic element 32 can be a spring or elastic rubber to provide sufficient elastic force to push the movement of the locking tongue 31.

[0041] This application significantly improves the retraction and locking efficiency of the latch 31 when the cover 2 is closed by designing a first guide surface 311 on the latch 31. The first guide surface 311 is set at an acute angle to the movement direction of the latch 31, allowing the elastic mating member 4 to smoothly push the latch 31 back when the cover 2 is closed, ensuring that the latch 31 can accurately enter the locking channel 4a and achieve locking. This design not only improves the reliability and stability of the locking process but also reduces the force required by the user to close the cover 2, enhancing the user experience. For example, in actual use, the user only needs to gently close the cover 2, and the elastic mating member 4 will push the latch 31 back and lock through the first guide surface 311, making the operation simple and effortless. In addition, this design also reduces wear between the latch 31 and the elastic mating member 4, extending their service life and further improving the overall durability and reliability of the headphone case.

[0042] Please see Figures 2 to 5In order to enable the elastic fitting 4 to retract the latch 31 and release the locking space when the user opens the cover 2, the latch 31 has a second guide surface 312 on the side facing away from the first guide surface 311. The second guide surface 312 is set at an acute angle to the movement direction of the latch 31. When the cover 2 is opened, the elastic fitting 4 can abut against the second guide surface 312 to retract the latch 31.

[0043] In one embodiment of this application, when the user begins to open the cover 2, the engaging section 42 of the elastic engaging member 4 gradually approaches the second guide surface 312 of the latch 31. Since the second guide surface 312 and the movement direction of the latch 31 are set at an acute angle β, the contact between the elastic engaging member 4 and the second guide surface 312 generates an inward component force, pushing the latch 31 back into the housing 1. As the cover 2 is further opened, the latch 31 continues to retract under the action of the elastic member 32 until the latch 31 completely exits the locking channel 4a, releasing the cover 2. For example, the second guide surface 312 can be designed as a slope with an angle β of approximately 15° to 45° to ensure that the latch 31 can be smoothly pushed back when the cover 2 is opened. The latch 31 can be made of high-strength plastic or aluminum alloy to ensure its durability during long-term use. The elastic member 32 can be a spring or elastic rubber to provide sufficient elastic force to push the movement of the latch 31. It should be noted that the tilt angles of the first guide surface 311 and the second guide surface 312 do not need to be the same. They only need to match the elastic force between the elastic element 32 and the elastic segment 41 to ensure that the cover 2 will not be accidentally opened after it is closed.

[0044] This application significantly improves the retraction and release efficiency of the locking tongue 31 when the cover 2 is opened by designing a second guide surface 312 on the locking tongue 31. The second guide surface 312 is set at an acute angle to the movement direction of the locking tongue 31, allowing the elastic mating member 4 to smoothly push the locking tongue 31 back when the cover 2 is opened, ensuring that the locking tongue 31 can accurately exit the locking channel 4a and release the cover 2. This design not only improves the reliability and stability of the release process, but also reduces the force required by the user to open the cover 2, enhancing the user experience. For example, in actual use, the user only needs to gently open the cover 2, and the elastic mating member 4 will push the locking tongue 31 back through the second guide surface 312 to release the locking channel 4a, making the operation simple and effortless. In addition, this design also reduces wear between the locking tongue 31 and the elastic mating member 4, extending the service life of both and further improving the overall durability and reliability of the headphone case.

[0045] Please see Figure 2 and Figure 9 The locking component 3 also includes an elastic element 32, the two ends of which elastically abut against the box body 1 and the locking tongue 31, respectively.

[0046] In this embodiment, an elastic element 32 is provided within the locking assembly 3. The elastic force of the elastic element 32 ensures that the locking tongue 31 returns to its normal position during locking and releasing with the locking channel 4a. The elastic element 32 can be a high-strength spring or elastic rubber. During normal installation, the elastic element 32 remains compressed, ensuring that the locking tongue 31 remains firmly against the inner wall of the housing 1, thereby achieving a better locking effect. Simultaneously, the elastic element 32 further ensures the stability of the entire locking assembly 3. Even in the event of minor external impacts or vibrations, the locking tongue 31 can still stably abut against the housing 1. This structure, when applied to an earphone case, can also improve the quality of the earphone case.

[0047] Please see Figures 8 to 9 In order to enable the locking tongue 31 to slide along the predetermined track, the box body 1 is provided with a first guide groove 1c, the locking tongue 31 is slidably disposed in the first guide groove 1c, and the two ends of the elastic member 32 along the sliding direction of the locking tongue respectively abut against the side wall of the first guide groove 1c and the locking tongue 31.

[0048] In the embodiments of this application, the shape and size of the first guide groove 1c are designed according to the shape and sliding path of the latch 31 to ensure that the latch 31 can slide freely in the groove without jamming. The first guide groove 1c can be designed as a rectangular groove, the length direction of which is consistent with the sliding direction of the latch 31, and the width and depth are adjusted according to the size of the latch 31. The overall size of the first guide groove 1c is relatively large, which can accommodate the latch 31 and the elastic member 32. The end of the first guide groove 1c near the latch 31 is the receiving groove 1b, and the end of the latch 31 away from the elastic member 32 abuts against the side wall of the receiving groove 1b. When the cover 2 is rotated to close, the mating section 42 will push the latch 31 open and then enter the receiving groove 1b. Due to the elastic force of the elastic member 32, the latch 31 will quickly return to its original position after being pushed open by the mating section 42, and then the latch 31 will extend into the locking channel 4a, locking the mating section 42 in the receiving groove, forming the closed state of the cover 2. The elastic element 32 can be a spring or elastic rubber, with its two ends fixed to the side wall of the first guide groove 1c and the lock tongue 31 respectively along the sliding direction of the latch 31 to provide appropriate elastic force. In actual assembly, the lock tongue 31 is placed in the first guide groove 1c, and the two ends of the elastic element 32 are connected to the groove wall and the lock tongue 31 respectively, ensuring that the lock tongue 31 is always subjected to a stable elastic force during sliding. This design not only improves the sliding accuracy of the lock tongue 31, but also enhances its reliability during use.

[0049] This application significantly improves the sliding accuracy and reliability of the locking tongue 31 by creating a first guide groove 1c on the housing 1 and sliding the locking tongue 31 within the guide groove. The two ends of the elastic element 32 abut against the side wall of the first guide groove 1c and the locking tongue 31 respectively, ensuring that the locking tongue 31 is always subjected to a stable elastic force during sliding, thereby avoiding locking or unlocking failures due to uneven sliding of the locking tongue 31. In actual use, even with frequent use or minor impacts, the locking tongue 31 can still slide smoothly within the first guide groove 1c, ensuring that the opening and closing function of the cover 2 remains normal. Furthermore, this design simplifies the assembly process, reduces production costs, improves production efficiency, and further enhances the product's market competitiveness.

[0050] Please see Figure 5 , Figure 8 as well as Figure 9 To further prevent the locking tongue 31 from shifting or rotating, a second guide groove 1d is provided on the side wall of the first guide groove 1c extending along the sliding direction of the locking tongue 31, and a guide platform 313 is provided on the locking tongue 31, which is slidably disposed in the second guide groove 1d.

[0051] In this embodiment, the shape and size of the second guide groove 1d match the guide platform 313, ensuring that the guide platform 313 can slide smoothly within the groove while preventing the latch 31 from shifting or rotating laterally or longitudinally. For example, the second guide groove 1d can be designed as a rectangular or T-shaped groove, with its length direction aligned with the sliding direction of the latch 31, and its width and depth adjusted according to the dimensions of the guide platform 313. The guide platform 313 can be made of the same material as the latch 31, such as high-strength plastic or aluminum alloy, to ensure its durability during long-term use. In actual assembly, the guide platform 313 is first placed in the second guide groove 1d, and then the latch 31 is installed in the first guide groove 1c, ensuring that the guide platform 313 can slide freely within the second guide groove 1d without becoming loose. This design, through a dual-guide structure, significantly improves the stability and reliability of the latch 31.

[0052] This application further prevents the locking tongue 31 from shifting or rotating during sliding by creating a second guide groove 1d on the side wall of the first guide groove 1c and setting a guide platform 313 on the locking tongue 31. This dual-guide structure not only improves the sliding accuracy of the locking tongue 31 but also enhances its stability during use. For example, in actual use, even with frequent use or minor impacts, the locking tongue 31 can still slide smoothly under the dual constraints of the first guide groove 1c and the second guide groove 1d, ensuring that the opening and closing function of the cover 2 is always normal. In addition, this design reduces wear between the locking tongue 31 and the guide groove, extends the service life of the locking tongue 31 and the guide groove, and further improves the overall durability and reliability of the headphone case.

[0053] Please see Figure 6 and Figure 8 To prevent unnecessary displacement of the elastic element 32 during compression and release, a first limiting hole 1e is provided on the side wall of the first guide groove 1c that abuts against the elastic element 32, and a second limiting hole 31a is provided on the end of the locking tongue 31 near the elastic element 32. The two ends of the elastic element 32 are respectively accommodated and limited by the first limiting hole 1e and the second limiting hole 31a.

[0054] In the embodiments of this application, the shape and size of the first limiting hole 1e and the second limiting hole 31a match the end of the elastic member 32, ensuring that the elastic member 32 can be stably held in a predetermined position during compression and release. For example, the first limiting hole 1e and the second limiting hole 31a can be designed as circular or square holes, with their diameter or side length adjusted according to the end size of the elastic member 32. The elastic member 32 can be a spring or elastic rubber, with its two ends inserted into the first limiting hole 1e and the second limiting hole 31a respectively, to ensure that the elastic member 32 can provide a stable elastic force during the sliding of the locking tongue 31, while preventing unnecessary displacement. In actual assembly, one end of the elastic member 32 is first inserted into the first limiting hole 1e, and then the locking tongue 31 is installed in the first guide groove 1c, so that the other end of the elastic member 32 is inserted into the second limiting hole 31a, thereby completing the assembly. This design significantly improves the stability and reliability of the elastic member 32 through the precise fit of the limiting holes.
