Description

Technical Field

[0001] The utility model belongs to the field of earphone bins, in particular to an opening structure of an earphone bin. Background Art

[0002] The design of the headphone compartment's lid opening structure has been constantly evolving and innovating throughout the development of headphones, mainly to meet users' needs for convenience, aesthetics, protection, and other aspects. The early headphone storage boxes had relatively simple lid opening methods, such as the common flip-top structure, which used a hinge connected to one end to flip the top cover open or closed. The operation was relatively intuitive, similar to the opening and closing of a common box lid, making it easy for users to quickly take and store headphones. As consumers' requirements for product appearance design continue to increase, the headphone compartment's lid opening structure has also become one of the design focuses. The unique lid opening method can increase the visual appeal and uniqueness of the headphones, making them more competitive in the market.

[0003] Some earphone compartments use a sliding cover structure, which opens and closes the compartment cover by sliding the upper and lower parts. This design can make the appearance of the earphone compartment more simple and smooth, without protruding hinge parts, enhancing the overall aesthetics.

[0004] The existing sliding-cover earphone compartment structure usually uses a sliding groove combined with magnetic suction to open and close. The magnetic suction requires magnets to be installed on the upper and lower parts of the earphone compartment respectively, and the overall structure is more complicated. After long-term use, the magnetism of the magnets will weaken and the adsorption force will decrease. In addition, the sliding-cover earphone compartment cannot reserve space for the display cable of the top cover. The cable will be worn due to pulling under long-term sliding, affecting the connection of the display.

[0005] To this end, those skilled in the art have proposed an opening structure for an earphone compartment to solve the problems raised in the background art. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an opening structure of the earphone compartment to solve the problem that the sliding cover type earphone compartment structure in the prior art is usually opened and closed by a sliding groove combined with magnetic attraction. The magnetic attraction requires magnets to be installed in the upper and lower parts of the earphone compartment respectively, and the overall structure is more complicated. After long-term use, the magnetism of the magnet will weaken and the adsorption force will decrease.

[0007] An earphone compartment cover opening structure comprises an earphone compartment and a cover body, wherein an opening and closing assembly and a cable connecting component are provided between the cover body and the earphone compartment;

[0008] The opening and closing assembly includes a second connecting column fixed on the surface of the earphone compartment, a guide groove opened on the bottom surface of the cover body, a first connecting column fixed on the surface of the cover body, and a torsion spring installed between the first connecting column and the second connecting column.

[0009] Preferably, the wiring connection component includes an assembly plate installed at the end surface of the earphone compartment, a through groove opened on the surface of the assembly plate, and a wire groove opened on the bottom surface of the cover body; the length of the wire groove is greater than the through groove, and the through groove is connected to the wire groove.

[0010] Preferably, a first connecting ring is provided at one end of the torsion spring, and a second connecting ring is provided at the other end of the torsion spring. The first connecting ring is connected to the first connecting column, and the second connecting ring is connected to the second connecting column. The upper surfaces of the first connecting column and the second connecting column are both provided with limiting portions.

[0011] Preferably, a snap groove is provided on the periphery of the cover body, and a sealing cover is installed on the upper surface of the cover body, and the sealing cover is engaged with the snap groove.

[0012] Preferably, a plurality of limit seats are fixed on the upper surface of the assembly plate, and a plurality of limit slots are provided on the bottom surface of the cover body.

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example 1: As shown in the attached Figure 1 To the attached Figure 5 As shown: The utility model provides an opening structure of an earphone compartment, comprising an earphone compartment 1 and a cover body 2, wherein an opening and closing component is provided between the cover body 2 and the earphone compartment 1;

[0026] The opening and closing assembly includes a second connecting column 4 fixed on the surface of the earphone compartment 1, a guide groove 202 opened on the bottom surface of the cover body 2, a first connecting column 3 fixed on the surface of the cover body 2, and a torsion spring 6 installed between the first connecting column 3 and the second connecting column 4.

[0027] When the cover 2 is pushed out, the second connecting post 4 is driven by the force of the torsion spring 6, and the second connecting post 4 is pushed out, so that the cover 2 and the earphone compartment 1 can be kept in a relatively stable state. When the cover 2 is pushed, the second connecting post 4 is driven to remain in a stationary state. At this time, the first connecting post 3 slides relative to the second connecting post 4. At this time, the first connecting ring 7 is squeezed toward the second connecting ring 8, and the torsion spring 6 is in an squeezed state. The torsion spring 6 will store elastic potential energy. When the first connecting ring 7 changes from being close to the second connecting ring 8 to being away from the second connecting ring 8, when the first connecting ring 7 is easy to be away from the second connecting ring 8, after the external force is removed, the potential energy of the torsion spring 6 will be converted into kinetic energy, causing the cover 2 to pop out, realizing the cover opening function. When the cover 2 is pushed out, the cover 2 can maintain a stable state. The cover 2 can be closed by the same principle.

[0028] By providing an opening and closing assembly, the relatively simple structure of the torsion spring not only facilitates manufacturing and assembly, reducing production costs, but also occupies less space, contributing to the product's miniaturization and lightweight design. The torsion spring provides a certain degree of elasticity, making the cover slide more smoothly and steadily without any lag or jerking. Whether opening or closing the cover, users can experience a comfortable operating experience, enhancing the user experience.

[0029] A buckle groove 14 is provided on the periphery of the cover body 2 , and a sealing cover 201 is mounted on the upper surface of the cover body 2 , and the sealing cover 201 is engaged with the buckle groove 14 .

[0030] A storage slot 17 is provided in the earphone compartment 1 , an earphone body 18 is provided in the storage slot 17 , a charging port 16 is provided on one side wall of the earphone compartment 1 , and a data interface 15 is provided on the other side wall of the earphone compartment 1 .

[0031] As can be seen from the above, when the user gently places his finger on the cover 2 and prepares to open the earphone compartment, due to the elastic assistance of the torsion spring 6, the user can feel a slight elastic feedback, which makes the cover in a stable closed state when it is not pushed.

[0032] When the user gently pushes cover 2 forward with their fingers, it begins to slide relative to earphone compartment 1. During this process, guide grooves 202 fixed to the bottom surface of cover 2 slide along the track on the surface of earphone compartment 1, ensuring a stable and accurate sliding direction. Simultaneously, as cover 2 slides, first connecting post 3 fixed to the surface of cover 2 slides relative to second connecting post 4 fixed to the surface of earphone compartment 1. At this point, first connecting ring 7 on first connecting post 3 presses against second connecting ring 8 on second connecting post 4, compressing torsion spring 6 and storing elastic potential energy.

[0033] The user continues to push cover 2 until they feel a certain resistance, then stops. At this point, torsion spring 6 is compressed to a certain degree, storing sufficient elastic potential energy. When the user removes the external force, the potential energy of torsion spring 6 is converted into kinetic energy, causing cover 2 to quickly pop open. At the moment of popping open, the user feels a light, effortless feel as cover 2 opens, revealing earphone body 18 within storage slot 17.

[0034] After using the earphones, the user prepares to return the earphones to the earphone compartment 1 and close the cover 2. The user gently places the earphones into the storage slot 17, ensuring that the earphones are stable. The user gently pushes the cover 2 with their fingers, causing it to slide toward the earphone compartment 1. During this sliding process, the first connecting post 3 slides relative to the second connecting post 4 again, and the first connecting ring 7 gradually approaches the second connecting ring 8, and the torsion spring 6 is compressed again.

[0035] When the cover body 2 completely covers the earphone compartment 1, the sealing cover 201 engages with the buckle groove 14 to ensure that the cover body 2 is tightly closed; at this time, the torsion spring 6 is in a compressed state, providing elastic potential energy for the next opening of the cover.

[0036] Example 2: On the basis of Example 1, a cable connecting component is provided between the cover body 2 and the earphone compartment 1, and the cable connecting component includes an assembly plate 9 installed at the end face of the earphone compartment 1, a through groove 19 opened on the surface of the assembly plate 9, and a wire groove 10 opened on the bottom surface of the cover body 2; the length of the wire groove 10 is greater than the through groove 19, and the through groove 19 is connected to the wire groove 10; after the cover body 2 slides relative to the earphone compartment 1, the through groove 19 is still connected to the wire groove 10.

[0037] Several limit seats 12 are fixed on the upper surface of the assembly plate 9, and several limit grooves 11 are also opened on the bottom surface of the cover body 2. The limit seats 12 slide with the limit grooves 11. The upper surface of the limit seat 12 is opened with connecting holes 13, and screws are installed at the connecting holes 13.

[0038] As can be seen from the above, the limit seat 12 and the limit groove 11 can limit the sliding of the cover 2. The screws can not only fix the assembly plate 9 to the earphone compartment 1, but the outer edge of the nut can also limit the cover 2.

[0039] During the sliding process of the cover body 2, the through slot 19 is located at one end of the wire groove 10 before sliding. At this time, the cable is connected to the display component at the installation slot sealing cover 201 through the through slot 19 and the wire groove 10; when the cover body 2 is pushed open, the through slot 19 is at the other end of the wire groove 10. During this process, the cable is always connected to the wire groove 10 through the through slot 19. Since only the wire groove 10 slides and the wire groove 10 is a long groove, the cable will not be rubbed by the wire groove 10. Therefore, this structure effectively avoids the wear of the cable caused by the sliding of the groove body and improves the connection stability of the display component.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
