[0043] 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.

[0044] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] 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 The top view of the earphone fixing device according to the embodiment of the present invention is shown; Figure 3 The side view structure of the earphone fixing device according to the 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.

[0046] 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), and an earphone groove is arranged at the bottom of the ear handle of each earphone 2; an earphone box 1, a button 4 is arranged on the outside of the earphone box 1, two force transmission columns (first force transmission column 31 and second force transmission column 32) connected to the button 4 and arranged inside the earphone box 1, and an elastic metal lock connected to the two force transmission columns, and earphone compartments (first earphone compartment 61 and second earphone compartment 62) symmetrically distributed for accommodating the earphones 2 are arranged inside the earphone box 1; wherein, The two force transmission columns are interconnected and are respectively arranged on a side of the earphone box 1 close to the button 4 and a side away from the button 4. The force transmission column close to the button 4 is connected to the button 4, and the force transmission column away from the button 4 is movably connected to the earphone box 1; the elastic metal lock is arranged in each earphone compartment and corresponds to the position of the earphone groove. When the earphone 2 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 through the inner recess transmitted by the force transmission column.

[0047] exist Figure 2 , Figure 3 and Figure 4 In the embodiment, the earphones in the earphone box are fixed by a double-end locking method, and the force transmission columns are respectively arranged at the side of the earphone box 1 close to and away from the button 4. The two force transmission columns include a first force transmission column 31 and a second force transmission column 32. The force transmission column arranged at the side of the earphone box 1 close to the button 4 is the first force transmission column 31, and the force transmission column arranged at the side of the earphone box 1 away from the button 4 is the second force transmission column 32; the elastic metal lock includes a first elastic metal lock 512 connected to the first force transmission column 31, and a second elastic metal lock 521 connected to the second force transmission column 32.

[0048] In an embodiment of the present invention, the first force transmission column includes a first connecting part and two first non-metallic elastic sheets 51, wherein the middle part of the first connecting part is connected to the button 4, one end of the two first non-metallic elastic sheets 51 is movably connected to the two ends of the first connecting part through a first rotating device 71, and the other end is connected to the first elastic metal lock 512, and the middle part is connected to the earphone box 1 through a first torsion spring 72.

[0049] The first non-metallic elastic sheet 51 realizes the inner concavity and outer convexity of the first elastic metal lock buckle 512 through the first rotating device 71 and the first torsion spring 72 .

[0050] Among them, an elastic sheet groove 511 is arranged on the first non-metallic elastic sheet 51 at the connection point between the first non-metallic elastic sheet 51 and the first connecting part, and a force transmission column groove 311 is arranged on the first connecting part at the connection point between the first non-metallic elastic sheet 51 and the first connecting part, wherein the first rotating device 71 moves in the force transmission column groove 311 and the elastic sheet groove 511.

[0051] The first rotating device 71 includes a rotating wheel, and the rotating wheel moves along the force transmission column sliding groove 311 and the elastic sheet groove 511 to realize the rotation and up-and-down displacement movement of the first non-metallic elastic sheet 51 .

[0052] Among them, the locking process through the first elastic metal lock buckle 512 is: when the earphone 1 is placed in the first earphone compartment 61, the first elastic metal lock buckle 512 is compressed by force to make the first torsion spring 72 concave; when the earphone 2 is completely placed in the first earphone compartment 61, the force disappears, and the first torsion spring 72 drives the first elastic metal lock buckle 512 to convexly lock.

[0053] Among them, the process of unlocking through the first torsion spring 72 is as follows: the button 4 is pressed by an external force, and the external force is applied to the first non-metallic elastic sheet 51 at both ends through the first force transmission column 31, and the first non-metallic elastic sheet 51 rotates around the first torsion spring 72, and the first torsion spring 72 is moved upward to make the first elastic metal lock buckle 512 concave and unlocked.

[0054] In an embodiment of the present invention, the second force transmitting column 32 includes an extension portion 321, a second connecting portion 322, and two second non-metallic spring sheets 52. One end of the extension portion 321 is connected to the button 4, and the other end passes through the interior of the earphone box 1 to a side away from the button 4 and vertically connects to the second connecting portion 322. The second connecting portion 322 is connected to the second elastic metal lock 521. One end of the two second non-metallic spring sheets 521 is respectively connected to the two ends of the second connecting portion 322, and the other end is connected to the second elastic metal lock 521.

[0055] A second torsion spring 73 is disposed at one end of the second non-metallic elastic sheet 52, and the second non-metallic elastic sheet 52 is movably connected to the second connecting portion 322 via the second torsion spring 73. The second non-metallic elastic sheet 52 realizes the inner concavity and outer convexity of the second elastic metal lock 521 via the second torsion spring 73.

[0056] Among them, the locking process through the second elastic metal lock buckle 521 is as follows: when the earphone 2 is placed in the second earphone compartment 62, the second elastic metal lock buckle 521 is compressed by force to make the second torsion spring 73 concave; when the earphone 2 is completely placed in the second earphone compartment 62, the force disappears, and the second torsion spring 73 drives the second elastic metal lock buckle 521 to convexly lock.

[0057] The second connection part 322 is connected to the earphone box 1 through a spring 74. The second connection part 322 is subjected to force and moves along the force direction to compress the spring 74. When the force disappears, the spring 74 rebounds to its original state.

[0058] Among them, the process of unlocking by the spring 74 is as follows: the button 4 is pressed by external force, and the second non-metallic elastic sheet 52 is driven to move along the force direction through the second force transmission column 32. The second non-metallic elastic sheet 52 will cause the second elastic metal lock to be recessed and unlocked under the action of the spring 74.

[0059] In an embodiment of the present invention, the earphone 2 is fixed by the first elastic metal lock buckle 512 contacting with the corresponding earphone groove. The contact point between the first elastic metal lock buckle 512 and the corresponding earphone groove can not only lock the earphone but also serve as a charging port for charging the earphone. The earphone 2 is fixed by the second elastic metal lock buckle 521 contacting with the corresponding earphone groove. The contact point between the second elastic metal lock buckle 521 and the corresponding groove can not only lock the earphone but also serve as a charging port for charging the earphone. The first elastic metal lock buckle, the second elastic metal lock buckle and the corresponding earphone groove together constitute an earphone charging pin point, wherein the earphone charging pin point is set in the earphone compartment, and when the earphone is locked, the two pin points are connected for charging.

[0060] 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 first non-metallic elastic sheet 51, and the first non-metallic elastic sheet 51 is rotated through the first 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 first non-metallic elastic sheet 51 rotates to fix the elastic metal lock 512 to the first earphone compartment 61 to fix the earphone. When the button 4 is pressed, the first non-metallic elastic sheet 51 is rotated around the first torsion spring 72 by the first force transmission column 31 driven by the button 4, and the top track is an arc, so the first 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 elastic metal lock is reset when the button 4 is released.

[0061] At the same time, when the earphone 2 is inserted into the earphone box 1, it is stressed and transmits the force to the second non-metallic elastic sheet 52. The second non-metallic elastic sheet 52 is stressed and winds around the second torsion spring 73. When the earphone 2 is completely placed in the earphone box 1, the second non-metallic elastic sheet 52 rotates to make the elastic metal lock 521 contact with the earphone groove of the corresponding earphone, and fixes the earphone in the second earphone compartment 62 to fix the earphone. When the button 4 is pressed, the second force transmission column 32 drives the second non-metallic elastic sheet 52 to press the spring 74 to bring the second elastic metal lock 521 out of the second earphone compartment 62 to unlock, and the second elastic metal lock is reset when the button is released.

[0062] It can be seen from the above embodiments that the earphone fixing device provided by the present invention fixes the earphone in the earphone box in a double-end locking manner by respectively arranging the first force transmission column and the second force transmission column on the side close to and away from the button inside the earphone box, and combining the first force transmission column, the second force transmission column, the elastic metal locking assembly and the earphone groove arranged at the end of the earphone, thereby preventing the earphone from falling out of the earphone box 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.
