[0002] Earphones have become an indispensable accessory in people's daily lives. Earphones need to be placed in an earphone box when not in use. Currently, most earphones are fixed in the earphone box by magnets. After falling, the earphones are easily separated from the earphone box and lost. Since the earphones are fixed to the earphone box by magnets, magnetic materials are installed in the earphones, which increases the weight of the earphones and the earphone box. Summary of the invention

[0003] In view of the above problems, an object of the present invention is to provide an earphone fixing device to solve the problem that the earphone is easily lost after falling and the earphone and earphone box are heavy due to the magnetic structure.

[0004] The present invention provides an earphone fixing device, comprising:

[0005] Two earphones, each earphone having an earphone groove at the bottom of the ear handle;

[0006] An earphone box, wherein a button is arranged on the outside of the earphone box, a force transmission column connected to the button and arranged inside the earphone box, and an elastic metal lock buckle connected to the force transmission column, and an earphone compartment for accommodating the earphones and symmetrically distributed is arranged inside the earphone box; wherein,

[0007] The force transmission column includes a connecting portion and two non-metallic spring sheets, wherein the connecting portion is connected to the elastic metal lock buckle through the non-metallic spring sheets, one end of the non-metallic spring sheet is movably connected to the connecting portion, and the other end is connected to the elastic metal lock buckle;

[0008] The elastic metal lock is arranged in each earphone compartment and corresponds to the position of the earphone groove. When the earphone is fully placed in the earphone compartment, the elastic metal lock is locked in the earphone groove. When the button is pressed, the elastic metal lock is unlocked by the inner recess transmitted by the force transmission column.

[0009] In addition, a preferred solution is that the middle part of the connecting part is connected to the button, one end of the two non-metallic springs are movably connected to the two ends of the connecting part through a first rotating device, and the middle part is connected to the earphone box through a torsion spring.

[0010] In addition, a preferred solution is that the non-metallic elastic sheet realizes the inner concavity and outer convexity of the elastic metal lock through the first rotating device and the torsion spring.

[0011] In addition, a preferred solution is that an elastic sheet groove is provided on the non-metallic elastic sheet at the connection between the non-metallic elastic sheet and the connection part, and a force transmission column slide groove is provided on the connection part at the connection between the non-metallic elastic sheet and the connection part, wherein:

[0012] The first rotating device moves in the force transmission column sliding groove and the elastic sheet groove.

[0013] In addition, a preferred solution is that the first rotating device includes a rotating wheel, and the rotating wheel moves along the force transmission column slide groove and the elastic sheet groove to realize the rotation and up and down displacement movement of the non-metallic elastic sheet.

[0014] In addition, a preferred solution is that when the earphone is placed in the earphone compartment, the elastic metal lock is compressed by force to make the torsion spring concave, and when the earphone is completely placed in the earphone compartment, the force disappears, and the torsion spring drives the metal lock to convexly lock.

[0015] In addition, a preferred solution is that the button is pressed by external force, and the external force is applied to the non-metallic elastic sheets at both ends through the force transmission column. The non-metallic elastic sheets rotate around the torsion spring, and the first rotating device moves upward to unlock the metal lock buckle.

[0016] In addition, a preferred solution is that the earphone groove is arranged at the near-ear end of the earphone.

[0018] In addition, a preferred solution is to provide a retractable charging port at the bottom of the earphone compartment for charging the earphones in the earphone box.

[0019] It can be seen from the above technical solution that the earphone fixing device provided by the present invention fixes the earphone in the earphone box in a single-ended locking manner by combining a force transmission column, an elastic metal lock buckle and an earphone groove arranged on the earphone. When the earphone is fully placed in the earphone compartment, the elastic metal lock buckle is locked in the earphone groove. When the button is pressed, the elastic metal lock buckle is unlocked by the inner recess transmitted by the force transmission column; thereby preventing the earphone from falling off the earphone box easily after falling. In addition, compared with the traditional magnetic suction structure, this device structure can effectively reduce the weight of the earphone and the earphone box.

[0036] In order to solve the aforementioned problem that the earphones are easily lost after falling and the earphones and the earphone box are heavy due to the magnetic attraction structure, the present invention proposes an earphone fixing device.

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In order to illustrate the structure of the earphone fixing device provided by the present invention, Figures 1 to 4 The structure of the earphone fixing device is exemplarily indicated from different angles. Specifically, Figure 1 An earphone fixing device according to an embodiment of the present invention is shown; Figure 2 1. The side view structure of the earphone fixing device according to the embodiment of the present invention is shown; Figure 3 The top view structure of the earphone fixing device according to an embodiment of the present invention is shown; Figure 4 The three-dimensional structure of the earphone fixing device according to the embodiment of the present invention is shown.

[0039] like Figures 1 to 4As shown together, the earphone fixing device provided by the present invention includes: two earphones 2 (right earphone 21 and left earphone 22), each earphone 2 having an earphone groove at the bottom of the ear handle; an earphone box 1, a button 4 is arranged on the outside of the earphone box 1, a force transmission column 31 connected to the button 4 and arranged inside the earphone box 1, and an elastic metal lock buckle 512 connected to the force transmission column 31, and an earphone compartment 61 symmetrically distributed for accommodating the earphones 2 is arranged inside the earphone box 1; wherein the force transmission column 31 includes a connecting portion, two non-metallic spring sheets 51, The connecting part is connected to the elastic metal lock buckle 512 through the non-metallic spring sheet 51. One end of the non-metallic spring sheet 51 is movably connected to the connecting part, and the other end is connected to the elastic metal lock buckle 512. The elastic metal lock buckle 512 is arranged in each of the earphone compartments 61 and corresponds to the position of the earphone groove. When the earphone 2 is fully placed in the earphone compartment 61, the elastic metal lock buckle 512 is locked in the earphone groove. When the button 4 is pressed, the elastic metal lock buckle 512 is unlocked by the inner recess transmitted by the force transmission column 31.

[0040] exist Figure 2 and Figure 3 In the embodiment shown, the earphone 2 in the earphone box 1 is fixed by a single-end locking method, and the force transmission column 31 is arranged at one side of the earphone box near the button 4. The middle part of the connecting part is connected to the button 4, one end of the two non-metallic springs 51 is movably connected to the two ends of the connecting part through the first rotating device 71, and the middle part is connected to the earphone box through the torsion spring 72.

[0041] The non-metal elastic sheet 51 realizes the inner concavity and outer convexity of the elastic metal lock buckle 512 through the first rotating device 71 and the torsion spring 72 .

[0042] An elastic sheet groove 511 is provided on the non-metal elastic sheet 51 where the non-metal elastic sheet 51 is connected to the connecting portion, and a force transmission column slot 311 is provided on the connecting portion where the non-metal elastic sheet 51 is connected to the connecting portion, wherein the first rotating device 71 moves in the force transmission column slot 311 and the elastic sheet groove 511. The first rotating device 71 includes a rotating wheel, and the rotating wheel moves along the force transmission column slot 311 and the elastic sheet groove 511 to realize the rotation and up and down displacement of the non-metal elastic sheet 51.

[0043] Among them, the process of locking the earphone in the present invention is: when the earphone 2 is placed in the earphone compartment 61, the elastic metal lock buckle 512 is compressed by force to make the torsion spring 72 concave; when the earphone 2 is completely placed in the earphone compartment 61, the force disappears, and the torsion spring 72 drives the elastic metal lock buckle 512 to convexly lock.

[0044] Among them, the process of unlocking the earphones in the present invention is: the button 4 is pressed by an external force, and the external force is applied to the non-metallic elastic sheets 51 at both ends through the force transmission column 31, and the non-metallic elastic sheets 51 rotate around the torsion spring 72, and the first rotating device 71 is moved upward to make the elastic metal lock buckle 512 concave and unlocked.

[0045] Among them, the earphone groove is arranged at the near-ear end of the earphone 2. The earphone 2 is fixed by the elastic metal lock 521 contacting the earphone groove at the end of the ear handle of the earphone. The contact point between the elastic metal lock 521 and the earphone groove at the end of the ear handle of the earphone can not only lock the earphone but also serve as a charging port for charging the earphone. The elastic metal lock 512 is the pin point for the earphone box 1 to charge the earphone 2, and the pin point is arranged in the earphone compartment 61. The first metal lock and the corresponding earphone groove form the pin point for charging the earphone box, and when the earphone 2 is locked, the two pin points are connected for charging. In addition, a telescopic charging port 81 is provided at the bottom of the earphone compartment 61 for charging the earphone 2 in the earphone box 1.

[0046] The working principle of the earphone fixing device of the present invention is as follows: when the earphone 2 is inserted into the earphone box 1, it is subjected to force and transmits the force to the non-metallic elastic sheet 51, and the non-metallic elastic sheet 51 is rotated through the torsion spring 72 and the force transmission column slot 311 (sliding from the right end to the left end). When the earphone 2 is completely placed in the earphone box, the non-metallic elastic sheet 51 rotates to fix the elastic metal lock 512 to the earphone compartment 61 to fix the earphone. When the button 4 is pressed, the non-metallic elastic sheet 51 is horizontally pressed by the force transmission column 31 driven by the button 4 and rotates around the torsion spring 72. The top track is an arc, so the non-metallic elastic sheet 51 can achieve a slight upward slide in the elastic sheet groove 511 through the first rotating device 71, and the metal lock is reset when the button 4 is released.

[0047] It can be seen from the above embodiments that the present invention provides a single-ended locking method for fixing the earphone in the earphone box by combining the force transmission column, the elastic metal lock and the earphone groove arranged on the earphone. When the earphone is fully placed in the earphone compartment, the elastic metal lock is locked in the earphone groove. When the button is pressed, the elastic metal lock is unlocked by the inner recess transmitted by the force transmission column; thereby preventing the earphone from falling out of the earphone box easily after falling. In addition, compared with the traditional magnetic suction structure, this device structure can effectively reduce the weight of the earphone and the earphone box.
