Description

Technical Field

[0001] This utility model relates to the field of wireless earphone storage and charging technology, specifically to an earphone charging device. Background Technology

[0002] Since wireless earbuds need to be charged to maintain their function after a period of use, corresponding earbud charging devices are provided, which not only store the earbuds but also charge them. In recent years, as earbud charging devices have become increasingly miniaturized, the internal space for storing the earbuds often uses an irregularly shaped, smooth curved surface design. This design, due to its small contact area and low friction, can make it difficult for users to remove the earbuds. As a result, a new type of earbud charging device has emerged that can automatically adjust the height of the earbuds during opening and closing.

[0003] The new headphone charging device theoretically solves the problem of inconvenience in taking out the headphones. However, in practical applications, the rotational force generated during the opening and closing process can cause the headphones to jam or even become stuck during the raising and lowering process. This affects the smooth opening and closing of the headphone charging device and the normal use of the headphones, causing inconvenience to users. Utility Model Content

[0053] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0054] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0055] This application provides an earphone charging device for storing and charging earphones. When the earphone charging device is in the open state, the earphones can extend out from the charging device, reducing the difficulty for users to retrieve them. When the earphone charging device is switched from the open state to the closed state, the earphones fall back into the earphone housing for storage. Furthermore, this earphone charging device, while enabling earphone lifting and lowering, also prevents the pushing component from jamming, ensuring smooth earphone lifting and lowering and improving user comfort. In this application, the earphones are wireless earphones, and the earphone charging device can charge the earphones inside.

[0056] Reference Figures 1-6 The earphone charging device includes a charging case body 1, an earphone sleeve 2, a case lid 3, and a pushing component 5. (See reference...) Figure 2 and Figure 5The case body 1 includes a receiving cavity 11 and an earphone receiving cavity 12 that are interconnected. The earphone receiving cavity 12 communicates with the external environment and is used to store the earphones. The case lid 3 rotates relative to the case body 1 to close or expose the opening of the earphone receiving cavity 12, so that the earphone charging device is in a closed or open state. One end of the earphone sleeve 2 extends into the earphone receiving cavity 12, and the other end extends into the receiving cavity 11. The earphone sleeve 2 abuts against the bottom of the earphone and can slide vertically within the earphone receiving cavity 12 to raise or lower the earphones. A pushing component 5 is disposed within the receiving cavity 11. One end of the pushing component 5 is connected to the case lid 3, and the other end is fixedly connected to the earphone sleeve 2. When the case lid 3 rotates open and closes relative to the case body 1, the case lid 3 drives the pushing component 5 to move, causing the earphone sleeve 2 to slide up and down within the earphone receiving cavity 12, thereby raising or lowering the earphones for easy access by the user.

[0057] Reference Figures 1-4 The lid 3 is rotatably connected to the body 1 via a rotating part 4 to facilitate the opening and closing of the headphone charging device. One end of the pushing component 5 is rotatably connected to the rotating part 4, and the other end is connected to the headphone sleeve 2. When the lid 3 and the body 1 open and close relative to each other, the rotating part 4 drives the pushing component 5 to move, thereby causing the headphone sleeve 2 to rise and fall within the headphone housing cavity 12.

[0058] Reference Figure 5 and Figure 6 The actuating component 5 includes a connecting rod 51, a lifting shaft 52, a lifting base 53, and a connecting member 54. One end of the connecting rod 51 (near the top) is movably connected to the rotating part 4, and the other end of the connecting rod 51 (near the bottom) is movably connected to one end of the lifting shaft 52 (the top). The other end of the lifting shaft 52 (the bottom) is movably connected to the lifting base 53, and the end of the lifting base 53 is connected to the earphone sleeve 2. Therefore, when the cover 3 rotates to open and close, the rotating part 4 can sequentially drive the connecting rod 51, the lifting shaft 52, and the lifting base 53 to move, ultimately causing the earphone sleeve 2 to move up and down within the earphone housing cavity 12, thereby raising and lowering the earphones inside the earphone sleeve 2.

[0059] Reference Figure 3 and Figure 4When the lid 3 flips open and closes, it provides an inclined axial rotational force F. The rotational force F is decomposed into a force f1 in the direction of gravity and a lateral force f2 in the front-back direction (the lateral force is perpendicular to the first rotating shaft 6). Under the force f1 in the direction of gravity, the lifting shaft 52 will move downward or upward; under the lateral force f2 in the front-back direction, the lifting shaft 52 will move forward or backward and tilt. Since the lifting shaft 52 is movably connected to the connecting rod 51 and the lifting base 53, the connecting rod 51, the lifting shaft 52, and the lifting base 53 will not jam when moving up and down with the rotating part 4 under the forces in both directions. This ensures the smooth opening and closing of the headphone charging device and the lifting of the headphones, improving the user experience.

[0060] Specifically, one end of the connecting rod 51 is rotatably connected to the rotating part 4 via the second rotating shaft 7, and the other end of the connecting rod 51 is rotatably connected to one end of the lifting shaft 52 via the third rotating shaft 8. Both the second rotating shaft 7 and the third rotating shaft 8 are arranged parallel to the first rotating shaft 6, as shown in the reference section. Figure 3 and Figure 4 .

[0061] Reference Figure 6 and Figure 7 The other end (i.e., the bottom end) of the lifting shaft 52 is provided with a groove 521, and the surface of the lifting base 53 is provided with a protrusion 531. The connecting piece 54 passes through the protrusion 531 and the groove 521 sequentially from bottom to top and connects to the lifting shaft 52, thereby connecting the lifting base 53 to the bottom of the lifting shaft 52. (Refer to...) Figure 3 and Figure 4 After the connecting piece 54 connects the lifting base 53 and the lifting shaft 52, the protrusion 531 on the lifting base 53 is located in the groove 521, and a movable gap is formed between the protrusion 531 and the groove 521, and a movable gap is formed between the connecting piece 54 and the protrusion 531. When the cover 3 is flipped open and closed, under the action of axial rotational force, the rotating part 4 drives the lifting shaft 52 to move up and down and back and forth laterally through the connecting rod 51. Since the lifting base 53 is restricted to moving only up and down, the back and forth lateral movement of the lifting shaft 52 can be converted into a back and forth tilting movement. The movable gap between the protrusion 531 and the groove 521 and the movable gap between the connecting piece 54 and the protrusion 531 allow the lifting shaft 52 to complete the back and forth tilting movement requirement, thereby avoiding problems such as jamming during opening and closing.

[0062] Reference Figure 6 The lifting base 53 is also provided with a through hole 532, which is longitudinally disposed within the protrusion 531. (See reference...) Figure 7 The lifting shaft 52 is also provided with a connecting hole 522, which is perpendicularly connected to the groove 521. (See reference...) Figure 6The connector 54 includes a connecting end 541 and a connecting rod portion 542. The lateral dimension of the connecting end 541 is larger than the diameter of the through hole 532, and the diameter of the connecting rod portion 542 is smaller than the diameter of the through hole 532. The diameter of the connecting rod portion 542 matches the size of the connecting hole 522. (Refer to...) Figure 3 and Figure 4 The connecting rod 542 passes through the through hole 532 from bottom to top and connects to the connecting hole 522, thereby movably connecting the lifting base 53 and the lifting shaft 52. The distance between the groove 521 and the connecting end 541 is greater than the thickness of the protrusion 531, creating a gap between the protrusion 531 and the groove 521, facilitating relative tilting movement between them. The diameter of the connecting rod 542 is smaller than the diameter of the through hole 532, allowing the connecting rod 542 to tilt within the through hole 532, thus enabling the lifting shaft 52 to drive the connecting member 54 to tilt back and forth.

[0063] Optionally, the connecting rod portion 542 is provided with an external thread, and the connecting hole 522 is provided with an internal thread, and the two are connected by threads. The size of the play can be determined by the length of the connecting rod portion 542 extending into the connecting hole 522.

[0064] In a preferred embodiment, the groove 521 is configured as a downward-opening spherical groove, and the protrusion 531 is a spherical protrusion. This allows the spherical surfaces to fit together, facilitating the tilting movement of the lifting shaft 52. It should be noted that the spherical groove and spherical protrusion refer to spherical structures less than or equal to a hemisphere. Besides this, the groove 521 and protrusion 531 can also be configured with other shapes, as long as they meet the requirements for forward and backward tilting.

[0065] The rotating part 4 is fixed to the lid 3. (Refer to...) Figure 5 and Figure 6 The rotating part 4 has a first shaft hole 41 and a second shaft hole 42 arranged in parallel, and a third shaft hole 111 is provided at the opening of the accommodating cavity 11. The first rotating shaft 6 is inserted into the third shaft hole 111 and the first shaft hole 41. The rotating part 4 rotates within the accommodating cavity 11 based on the first rotating shaft 6, thereby realizing the rotational opening and closing of the lid 3 and the body 1. Among them, two third shaft holes 111 are symmetrically provided, one third shaft hole 111 is installed on one side of the opening of the accommodating cavity 11, and the other third shaft hole 111 is installed on the other side of the opening of the accommodating cavity 11.

[0066] Reference Figure 6 One end of the connecting rod 51 is provided with a fourth shaft hole 511. The second rotating shaft 7 is inserted into the fourth shaft hole 511 and the second shaft hole 42, and the rotating part 4 can drive the connecting rod 51 to move based on the second rotating shaft 7.

[0067] Reference Figure 6The other end of the connecting rod 51 is provided with a fifth shaft hole 512, and one end of the lifting shaft 52 is provided with a sixth shaft hole 523. The third rotating shaft 8 is inserted into the fifth shaft hole 512 and the sixth shaft hole 523, and the lifting shaft 52 is rotatably connected to the connecting rod 51 based on the third rotating shaft 8.

[0068] In one embodiment, reference is made to... Figure 6 The rotating part 4 has a rotating shaft block 43 protruding from its edge, and a rotating block 44 protruding from its edge. A first shaft hole 41 is provided on the rotating shaft block 43, and a second shaft hole 42 is provided on the rotating block 44. The rotating block 44 is rotatably connected to the connecting rod 51 via a second rotating shaft 7.

[0069] Reference Figure 6 The connecting rod 51 includes a main body 513 and two first connecting arms 514. The two first connecting arms 514 extend parallel to each other on the top outer side of the main body 513, and each of the two first connecting arms 514 has a coaxial fourth shaft hole 511. A rotating block 44 can be inserted between the two first connecting arms 514, and a second rotating shaft 7 is inserted into the two fourth shaft holes 511 and the two second shaft holes 42 to connect the connecting rod 51 and the rotating block 44. Optionally, the edge of the rotating shaft block 43 has two spaced rotating blocks 44 protruding from it, and each of the two rotating blocks 44 has a coaxial second shaft hole 42. A first connecting arm 514 extends from the top outer side of the main body 513, and the first connecting arm 514 has a fourth shaft hole 511. The first connecting arm 514 is inserted between the two rotating blocks 44, and the second rotating shaft 7 is inserted into the fourth shaft hole 511 and the two second shaft holes 42 to connect the connecting rod 51 and the rotating block 44.

[0070] Reference Figure 6 The connecting rod 51 also includes two second connecting arms 515, which extend parallel to each other and are disposed on the outer side of the bottom of the main body 513. Each of the two second connecting arms 515 has a coaxial fifth shaft hole 512. (Refer to...) Figure 6 and Figure 7 The lifting shaft 52 has a connecting block 524 protruding from its top end, and the connecting block 524 has a sixth shaft hole 523. The connecting block 524 is inserted between two second connecting arms 515, and the third rotating shaft 8 is inserted into the two fifth shaft holes 512 and the sixth shaft hole 523 to connect the connecting rod 51 and the lifting shaft 52. Optionally, the lifting shaft 52 has two spaced-apart connecting blocks 524 protruding from its top end, and each of the two connecting blocks 524 has a coaxial sixth shaft hole 523. A second connecting arm 515 extends from the bottom outer side of the main body 513, and the second connecting arm 515 has a fifth shaft hole 512. The second connecting arm 515 is inserted between two connecting blocks 524, and the third rotating shaft 8 is inserted into the sixth shaft hole 523 and the fifth shaft hole 512 to connect the connecting rod 51 and the lifting shaft 52.

[0071] Reference Figure 6 The lifting base 53 includes a lifting plate 533 and a base 534. The lifting plate 533 is arranged parallel to the first rotating shaft 6, and a protrusion 531 is provided on the surface of the lifting plate 533 to facilitate connection with the lifting shaft 52. The base 534 is connected to the end of the lifting plate 533 and to the earphone sleeve 2, thereby allowing the lifting base 53 to drive the earphone sleeve 2 to move up and down, thus raising and lowering the earphone.

[0072] In one implementation, refer to Figure 2 and Figure 5 The headphone receiving cavity 12 includes two headphone receiving cavities 121 arranged side by side, which can hold both left and right headphones simultaneously. The two headphone receiving cavities 121 can be completely independent and not connected, or they can be partially connected at the top position; there are no specific restrictions. The bottom of both headphone receiving cavities 121 has a hollow structure.

[0073] Accordingly, the earphone sleeve 2 includes two earphone holders 21, which are slidably connected to two earphone receiving cavities 121 respectively. In this embodiment, the shape of the earphone holders 21 is not limited; they can be cylindrical or plate-shaped, as long as they can abut against the earphones.

[0074] Correspondingly, when the earphone sleeve includes two earphone trays 21, the lifting base 53 includes two bases 534, which are respectively connected to both ends of the lifting plate 533 and respectively connected to the two earphone trays 21 one-to-one. Preferably, the protrusion 531 is located in the middle of the lifting plate 533. That is, the earphone trays 21 are fixed on the bases 534. The earphone trays 21 can be fixedly connected to the bases 534 by means of bolts, clips, or integral molding.

[0075] Furthermore, a limiting groove 13 is provided within the accommodating cavity 11, as shown in the reference. Figure 3 and Figure 4 The opening of the limiting groove 13 faces the outside of the housing body 1, and the lifting shaft 52 is longitudinally moved within the limiting groove 13. The limiting groove 13 is used to restrict the lifting shaft 52 to move only in the direction of gravity and the front-back direction, and to prevent it from tilting or deflecting to the left or right, thereby ensuring the stability of the up-and-down movement of the earphone sleeve.

[0076] In one embodiment, reference is made to... Figures 2-4 The box body 1 includes a lower outer shell 15 and a lower inner shell 14. The lower outer shell 15 has a first receiving groove. The lower inner shell 14 is inserted into the top of the first receiving groove and is fixedly connected to the lower outer shell 15. The outer side wall of the lower inner shell 14 and the first receiving groove form a receiving cavity 11. That is, the lower outer shell 15 is installed outside the lower inner shell 14, and the lower inner shell 14 and the lower outer shell 15 surround and form the receiving cavity 11. (Refer to...) Figure 3 and Figure 4After the lower inner shell 14 is connected to the lower outer shell 15, the accommodating cavity 11 is provided with an opening near the top of the lower outer shell 15 so that the rotating part 4 can rotate at this position.

[0077] Reference Figure 5 The lower inner shell 14 has an inwardly recessed side forming a limiting groove 13. When the pushing assembly 5 is placed in the receiving cavity 11, the lifting shaft 52 can be limited within the limiting groove 13 to prevent deflection of the lifting shaft 52 during lifting. Preferably, the width of the limiting groove 13 is adapted to the width of the lifting shaft 52 or the end where the lifting shaft 52 and the connecting rod 51 are connected.

[0078] Reference Figure 2 and Figure 5 The lower inner shell 14 has an earphone receiving cavity 12, the bottom of which has a hollow structure and is connected to the receiving cavity 11 through the bottom hollow structure. The split design of the box body 1 is simple and reliable, making it easy to assemble the earphone sleeve 2 and the pushing component 5 and other parts into the receiving cavity 11, improving the aesthetics of the earphone charging device while realizing the raising and lowering of the earphone. Furthermore, the split design of the box body 1 improves the processing efficiency of the receiving cavity 11, reduces the production difficulty and cost of the box body 1, and simplifies the structure of the earphone charging device.

[0079] The shape of the earphone receiving cavity 12 is basically adapted to the shape of the earphone, so that the earphone will not shake after being placed in the earphone receiving cavity 12, preventing damage to the earphone during carrying and transportation. In this embodiment, the earphone receiving cavity 12 is set as a columnar structure near the bottom.

The two spring positioning pins are parallel to the first rotating shaft 6 and are rotatably inserted into the corresponding spring positioning holes 45.

[0087] The elastic element 9 switches positions between the open and closed states. In these two different positions, the tension of the elastic element 9 controls the automatic opening and closing of the headphone charging case lid. Simultaneously, the opening and closing process provides a damped tactile feedback, allowing the user to clearly feel the lid's position in their hand. The headphone charging device can automatically open and close, and when the lid is fully closed or fully open, the elastic element 9 consistently provides a spring-loaded force to the rotating part 4. This ensures excellent stability and tightness of the elastic element 9, preventing it from shaking when the headphone charging device is shaken. The opening and closing process feels very smooth.

[0088] Reference Figure 6 The headphone charging device also includes a conductive pin 10, a power supply, and a circuit board. The conductive pin 10 is fixed inside the headphone sleeve 2 and is used for electrical connection with the headphone inside the headphone sleeve 2. The power supply and the circuit board are fixed inside the receiving cavity 11 and are electrically connected to each other. The circuit board extends and is fixedly connected to the lower part of the headphone sleeve 2, and is electrically connected to the conductive pin 10. Since the conductive pin 10 is fixed inside the headphone sleeve 2, it can rise and fall with the headphone sleeve 2, thus ensuring continuous charging when the headphone is raised or lowered. The headphone charging device is also provided with a charging interface, which is located on the charging case body 1. The charging interface is electrically connected to the power supply for charging the power supply.

[0089] In one embodiment, the headphone charging device further includes a first magnetic element and a second magnetic element. The first magnetic element is disposed at the end of the cover 3 away from the rotating part 4, and the second magnetic element is disposed at the end of the body 1 away from the rotating part 4. When the cover 3 and the body 1 are fastened together, the first and second magnetic elements attract each other. Specifically, both the first and second magnetic elements are magnets and are magnetically attracted to each other. The arrangement of the first and second magnetic elements provides a locking force when the cover 3 and the body 1 are fastened together to seal the headphone receiving cavity 12, reducing the risk of losing the headphone due to accidental opening of the cover 3 and improving the headphone charging device's protection capability for the headphone.

[0090] In one embodiment, the case cover 3 includes an upper outer shell 32 and an upper inner shell 31. The upper outer shell 32 is provided with a second receiving groove, and the upper inner shell 31 is inserted into the top of the second receiving groove. The upper inner shell 31 is recessed with a cover groove 33. That is, the upper outer shell 32 is installed on the outside of the upper inner shell 31. When the case cover 3 is fastened to the case body 1, the cover groove 33 communicates with the earphone receiving cavity 12 to form a receiving space that perfectly matches the shape of the earphone and accommodates the head of the earphone. Thus, the arrangement of the earphone can be optimized by adjusting the size of the cover groove and the earphone receiving cavity 12, thereby further simplifying the layout of the earphone charging device and reducing the size and weight of the earphone charging device.
