[0036] See attached Figure 1 -Attached Figure 6 A novel ear hook connection structure comprises an earphone body 1, an ear hook 2 and a latch 3; a fixing seat 10 is provided inside the earphone body 1, and a slot 101 and a receiving slot 102 which are connected to each other are provided on the fixing seat 10, the slot 101 is open outward, the receiving slot 102 is located below the slot 101 and is perpendicular to the slot 101, and a card hole 102k is also provided on the slot wall of the receiving slot 102, and an adaptable card hook 20 is provided on the ear hook 2, and the card hook 20 can be placed in the receiving slot 102 and snap-fitted with a buckle; the latch 3 can be installed in the slot 101 and abut against the card hook 20.
[0037] Specifically, during installation, the ear hook 2 is passed through the earphone body 1 so that the hook 20 is placed in the receiving groove 102 and engages with the hole 102k. Then, the latch 3 is installed in the slot 101 and abuts against the hook 20 to enclose and fix the hook 20 in the receiving groove 102, so that the connection between the ear hook 2 and the earphone body 1 is completed, and finally the earphone body 1 can be packaged.
[0038] When disassembling, open the earphone body 1 to expose the fixing seat 10, and then perform maintenance work such as cleaning and repairing the electronic components inside it normally. If the ear hook 2 needs to be replaced, first remove the pin 3 from the slot 101 to release the restriction on the hook 20, and then move the hook 20 out of the hole 102k and the accommodating groove 102, and then the ear hook 2 can be removed from the earphone body 1.
[0039] In summary, the utility model completes the preliminary positioning by designing a hook 20 on the ear hook 2 to cooperate with the slot 101 and the hole 102k on the fixing seat 10, and by installing the pin 3 in the slot 101 to enclose and abut the hook 20, so that the hook 20 is installed as a whole on the fixing seat 10, thereby realizing the connection between the ear hook 2 and the earphone body 1; compared with the method of using glue or snap fastening, this design is not only simple to disassemble and assemble, convenient for early assembly and later maintenance, but also a cross structure is formed between the hook 20 and the pin 3, which has balanced force and high assembly stability, and is not easily worn and fallen off due to external pulling.
[0040] See attached Figure 4 -Attached Fig.10 The ear hook 2 can be integrally formed with the same material as a whole, but considering that the hook 20 is inconvenient to process during the actual production process; for this reason, in this embodiment, the ear hook 2 includes a wrap 21 and an inner core 22, the wrap 21 wraps the inner core 22, and when the ear hook 2 passes through the earphone body 1, the wrap 21 cooperates with the earphone body 1; the end of the inner core 22 passes through the wrap 21 and is integrally formed with the hook 20.
[0041] Specifically, during production, the end of the inner core 22 is first bent to form a hook 20, and then the main part of the inner core 22 is wrapped with the wrapping sleeve 21; among them, since the hook 20 is formed by bending the inner core 22, the production is relatively simple; and during assembly, after the ear hook 2 passes through the earphone body 1, the wrapping sleeve 21 cooperates with the earphone body 1. This design can prevent the connection between the ear hook 2 and the earphone body 1 from loosening, and has a certain waterproof effect.
[0042] See attached Fig. 9 -Attached Fig.10 The wrapping sleeve 21 is made of plastic material, and the inner core 22 is made of memory metal.
[0043] Among them, the characteristic of plastic materials is that they can be significantly deformed under the action of external forces without being destroyed and have good ductility; while memory metals are special metal materials that can restore their original macroscopic shape in another temperature range after plastic deformation within a certain temperature range.
[0044] Relying on the characteristics of memory metal, the inner core 22 can be easily bent to form the hook 20, and in daily use, the shape of the main part of the inner core 22 can be adjusted as needed to perfectly fit the contours of ears of different sizes; and relying on the characteristics of plastic materials, the wrap 21 can follow the deformation of the inner core 22 to avoid wrinkles and cracks, thereby extending the overall service life of the ear hook 2.
[0045] Furthermore, there are various types of shaping materials, such as common rubber, flexible plastics, etc., which are not limited in the present invention. In order to further improve the user experience, in this embodiment, the shaping material is made of flexible plastics such as PVC and PTU; this type of material can prevent the ear hook 2 from generating static electricity and affecting the user experience, and has strong shaping ability, can perfectly wrap the inner core 22, and follow the deformation of the inner core 22.
[0046] See attached Fig. 9 -Attached Fig.10 The hook 20 is formed integrally by a hook body 201 and a hook head 202, the hook body 201 is placed in the accommodating groove 102, and the hook head 202 is engaged with the engaging hole 102k, and there is an angle α between the hook body 201 and the hook head 202, 60°≤α≤120°; wherein a stable triangular structure is formed between the hook body 201, the hook head 202 and the fixing seat 10, and within this angle range, the hook head 202 can be well stressed, ensuring that the hook head 202 will not separate from the engaging hole 102k when the ear hook 2 is pulled.
[0047] See attached Fig. 9 -Attached Fig.10 The card hole 102k is designed vertically and perpendicular to the accommodating groove 102, and the angle α between the hook body 201 and the hook head 202 is 90°. At this angle, the hook head 202 is subjected to the greatest force, so that the installation stability of the card hook is the highest.
[0048] See attached Figure 5 -Attached Fig. 9 The slot 101 is provided with a socket 101k on both sides of the receiving groove 102, and the two sockets 101k are plugged and matched with the two ends of the plug 3, so that the plug 3 is fixed in the slot 101 and abuts against the hook 20; since the installation method of the plug 3 is various, the utility model does not limit this, and for the convenience of understanding, the following embodiments are cited as examples:
[0049] Embodiment 1
[0050] See attached Figure 5 -Attached Figure 6 The two sockets 101k are designed vertically and perpendicular to the slot 101, and the latch 3 is designed in a U shape, and its two ends are respectively vertically plugged into the two sockets 101k.
[0051] Specifically, during installation, hold the top of the pin 3 and align both ends with the two sockets 101k, then push the pin 3 downward in the vertical direction so that both ends of the pin 3 are plugged into the two sockets 101k until the pin 3 abuts against the hook 20, and the hook 20 can be enclosed and fixed in the accommodating groove 102.
[0052] Embodiment 2 (not shown)
[0053] The two insertion holes 101 k are arranged horizontally and connected to the slot 101 , and the plug 3 is in a straight line shape. When installing, the plug 3 is inserted into the two insertion holes 101 k so that the plug 3 can be surrounded and abutted against the hook 20 .
[0054] Specifically, hold one end of the latch 3 so that the other end of the latch 3 is aligned with a plug hole 101 k , and then push the latch 3 horizontally so that the latch 3 passes through the two plug holes 101 k in sequence, so that the hook 20 can be enclosed and abutted in the accommodating groove 102 .
[0055] Among them, compared with the first embodiment, the structure in the second embodiment can make the plug more stable after installation, but the horizontally designed pin 3 is inconvenient to hold, and a certain amount of movable space needs to be reserved beside the jack 101k before installation, so the internal space of the earphone body 1 needs to be expanded, resulting in a larger volume of the earphone body 1; while in the first embodiment, the U-shaped pin 3 can be directly installed through the opening of the slot 101, and it is convenient for workers to hold and install it, and it takes less time, so the structural design in the first embodiment is preferably adopted in the present invention.
[0056] See attached Figure 5 -Attached Fig. 9 The connection between the latch pin 3 and the socket 101k is an interference fit, which facilitates the disassembly and assembly of the latch pin 3 and forms a damping force between the latch pin 3 and the socket 101k. If the external force applied to the hook 20 is smaller than the damping force, the hook 20 will not fall off the accommodating groove 102.
[0057] It should be noted that, in addition to the above-mentioned method, a magnet may be provided in the socket 101k, and the plug 3 may be made of magnetic material, so that the plug 3 and the socket 101k are adsorbed and fixed by magnetic attraction; or glue may be directly used to adhere the plug 3 to the socket 101k; due to the variety of methods, this invention does not impose any restrictions on this.
[0058] See attached Figure 1 -Attached Figure 6The conventional earphone body 1 is directly composed of a shell (not shown in the figure) and a control unit (not shown in the figure) and a sound unit (not shown in the figure) installed inside the shell, which will cause the overall weight to be concentrated on the shell, resulting in uneven force on both ends of the ear hook 2; to solve this problem, in this embodiment, the earphone body 1 includes an ear cabin 11 and a control cabin 12, a sound unit is installed inside the ear cabin 11, a control unit is installed inside the control cabin 12, and a fixing seat 10 is provided inside the ear cabin 11 and the control cabin 12, and hooks 20 are provided at both ends of the ear hook 2, and the two ends of the ear hook 2 respectively penetrate into the ear cabin 11 and the control cabin 12, and the two hooks 20 are respectively connected to the two fixing seats 10.
[0059] Among them, since the ear cabin 11 and the control cabin 12 are respectively installed at both ends of the ear hook 2, the force on both sides of the ear hook 2 is evenly applied, so it can be hung on the ear more stably; in addition, the control unit and the sound unit are designed independently, which can also avoid the heat generated by the operation of the control unit to operate the sound unit.
[0060] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
