Description
Technical Field
[0001] This utility model relates to the field of wireless earphone storage and charging technology, specifically to an earphone charging case. Background Technology
[0002] As people's pursuit of quality of life continues to improve, their demand for headphones is also increasing, leading to the emergence of wireless headphones. Wireless headphones need to be charged after a period of use, therefore they are generally equipped with a corresponding charging case to store and charge the headphones.
[0003] As earphone charging cases become increasingly compact, the placement and removal surfaces of wireless earphones are often irregular, smooth curved surfaces. This small contact area and low coefficient of friction can make it difficult for users to remove the earphones. Therefore, charging cases with adjustable earphone height during opening and closing have gradually appeared on the market. While these charging cases do allow for earphone height adjustment, they are prone to wobbling and twisting during this process, potentially causing them to jam. This affects the smoothness of opening and closing of the charging case and the earphone height adjustment, impacting user experience. Utility Model Content

[0074] 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.
[0075] This application provides an earphone charging case for storing and charging earphones. When the charging case is open, the earphones can extend out, reducing the difficulty for users to retrieve them. When the charging case is closed, the earphones fall back into the earphone housing for storage. Furthermore, this earphone charging case, while enabling earphone raising and lowering, also prevents the pushing component from jamming, ensuring smooth earphone raising and lowering and improving user comfort. In this application, the earphones are wireless, and the charging case can charge the earphones inside.
[0076] First embodiment:
[0077] Reference Figures 1-3 The earphone charging case includes a case body 1, earphone sleeves 2, a case lid 3, and a pushing assembly 5. (See reference...) Figure 2 and Figure 3The charging case 1 includes a receiving cavity 11 and an earphone receiving cavity 12 that are interconnected. The earphone receiving cavity 12 is in communication with the external environment and is used to store earphones. The lid 3 rotates relative to the charging case 1 to close or expose the opening of the earphone receiving cavity 12, so that the earphone charging case 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 is used to abut against the bottom of the earphone. The earphone sleeve 2 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 lid 3, and the other end is fixedly connected to the earphone sleeve 2. When the lid 3 rotates open and closes relative to the charging case 1, the 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.
[0078] Reference Figure 6 The accommodating cavity 11 has a longitudinally penetrating blocking groove 13. The pushing component 5 is movably disposed within the blocking groove 13, with its two ends extending from the upper and lower ends of the blocking groove 13 and connecting to the case cover 3 and the earphone sleeve 2, respectively. The blocking groove 13 restricts the pushing component 5, ensuring that the restricted part can only move in the direction of gravity (vertical direction) without deflection, thereby improving the stability of the pushing component 5's movement. Furthermore, it ensures that the parts remain stable and do not produce abnormal noises after the earphone charging case is dropped.
[0079] Reference Figure 4 The earphone charging case also includes a connecting plate 6, which is disposed within the receiving cavity 11. The connecting plate 6 is connected to the case body 1 to form a longitudinally penetrating blocking groove 13. In this embodiment, a limiting plate 16 extends upward from the bottom surface of the receiving cavity 11, as shown in the figure. Figure 6 The connecting plate 6 and the limiting plate 16 are connected to form a vertically continuous blocking groove 13. The connecting plate 6 and the limiting plate 16 can be fixedly connected by bolts, clips, or other means.
[0080] In one implementation, the limiting plate 16 includes a main body 161 and two L-shaped limiting parts 162. The two L-shaped limiting parts 162 are symmetrically arranged at both ends of the main body 161, and a first slot is formed between each of the two L-shaped limiting parts 162 and the main body 161. Specifically, the first part of each of the two L-shaped limiting parts 162 is parallel to the main body 161, and the second part of each of the two L-shaped limiting parts 162 is perpendicular to the main body 161, thereby forming a first slot between the first part of each of the two L-shaped limiting parts 162 and the main body 161. A lateral opening for the connecting plate 6 to extend is formed between the first parts of the two L-shaped limiting parts 162.
[0081] The connecting plate 6 includes a bent portion 61 and two flat portions 62, which are respectively connected to both ends of the bent portion 61 and extend in opposite directions. (Refer to...) Figure 5Two flat portions 62 are respectively engaged in two first slots, and a curved portion 61 extends from the opening and surrounds the main body portion 161 to form a blocking groove 13. Preferably, the curved portion 61 is U-shaped, and after being fixedly connected with the limiting plate 16, it can form a rectangular blocking groove 13, which facilitates the restriction of the pushing component 5.
[0082] In this embodiment, refer to Figures 2-3 The box body 1 includes a lower outer shell 15 and a lower inner shell 14. The lower outer shell 15 is provided with 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 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 to form the receiving cavity 11. Specifically, the limiting plate 16 extends upward from the inner bottom surface of the lower outer shell 15. The position of the limiting plate 16 inside the lower outer shell 15 will not interfere with the lower inner shell 14.
[0083] In other possible implementations, the connecting plate 6 can also be directly connected to the inner wall of the lower outer shell 15 or the outer wall of the lower inner shell 14 to form a blocking groove 13.
[0084] Reference Figure 4 and Figure 5 The pushing component 5 includes an arc-shaped connecting rod 521, a C-shaped connecting piece 522, a lifting base plate 523, and a vertical connecting piece 524. One end of the arc-shaped connecting rod 521 (i.e., the end near the top) is rotatably connected to the cover 3 via a second rotating shaft 7. The C-shaped connecting piece 522 has horizontally extending sliding grooves 50 on its opposite sides. The other end of the arc-shaped connecting rod 521 extends into the opening of the C-shaped connecting piece 522 and is movably connected to the sliding groove 50 via a third rotating shaft 8. Both ends of the vertical connecting piece 524 are connected to the C-shaped connecting piece 522 and the lifting base plate 523, respectively. The end of the lifting base plate 523 is fixedly connected to the earphone sleeve 2. The curvature of the arc-shaped connecting rod 521 can be set according to requirements, such as... Figure 5 and Figure 14 As shown. The opening orientation of the C-shaped connecting piece 522 is not limited and can be set according to actual needs.
[0085] Reference Figure 8 and Figure 9When 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 40). Under the force f1 in the direction of gravity, the pushing component 5 will move downward or upward; under the lateral force f2 in the front-back direction, the arc-shaped connecting rod 521 will move forward or backward. Since the arc-shaped connecting rod 521 is movably connected to the sliding groove 50 of the C-shaped connecting piece 522 through the third rotating shaft 8, the pushing component 5 can move up and down as a whole under the forces in both directions, and at the same time, the arc-shaped connecting rod 521 and the C-shaped connecting piece 522 can move horizontally in the front-back direction. This can prevent the pushing component from getting stuck during the opening and closing of the earphone charging case, ensuring the smooth opening and closing of the earphone charging case and the raising and lowering of the earphones, and improving the user experience.
[0086] The C-shaped connecting piece 522 is located above the blocking groove 13, and the lifting base plate 523 is located below the blocking groove 13. A vertical connecting piece 524 extends through the blocking groove 13, with both ends connecting to the C-shaped connecting piece 522 and the lifting base plate 523 respectively. This design ensures relative horizontal movement between the arc-shaped connecting rod 521 and the C-shaped connecting piece 522 in the front-to-back direction, while also allowing the vertical connecting piece 524 to move only in the direction of gravity (vertical direction) without deflection. This improves the stability of the moving component 5 and ensures that the parts remain stable and do not make any abnormal noises after the earphone charging case is dropped. Since the C-shaped connecting piece 522, the lifting base plate 523, and the vertical connecting piece 524 are rigidly connected and form an integral structure, their movements are synchronized. The size of the blocking groove 13 is adapted to the cross-sectional area of the vertical connecting piece 524. The vertical connecting piece 524 moves longitudinally within the blocking groove 13, thereby restricting the movement of the C-shaped connecting piece 522, the lifting base plate 523, and the vertical connecting piece 524 in the front-back and left-right directions, ensuring that the headphone sleeve 2 connected to it can only move along the direction of gravity to achieve a good headphone lifting function.
[0087] Reference Figure 5 The lifting base plate 523 includes a middle connecting rod and a lower connecting part. The middle connecting rod is arranged parallel to the first rotating shaft 40, the second rotating shaft 7, and the third rotating shaft 8. The lower connecting part includes a first rod and a second rod, which are connected to form an L-shape. The first rod is connected to the middle connecting rod, and the second rod is connected to the earphone sleeve 2. In this embodiment, the second rod extends to the bottom of the earphone sleeve 2 for connection. The lower connecting part can be integrally formed with the middle connecting rod, integrally formed with the earphone sleeve 2, or all three integrally formed.
[0088] Optionally, the C-shaped connecting piece 522 can be directly connected to the lifting base plate 523, and the vertical connecting piece 524 can also be connected below the C-shaped connecting piece 522, with the bottom end of the vertical connecting piece 524 extending downwards to the bottom of the lifting base plate 523, as shown in the figure. Figure 18 .
[0089] Reference Figures 1-3 The lid 3 is rotatably connected to the body 1 via a rotating part 4, facilitating the opening and closing of the earphone charging case. One end of the pushing component 5 is rotatably connected to the rotating part 4, and the other end is connected to the earphone sleeve 2. That is, one end of the arc-shaped connecting rod 521 is rotatably connected to the rotating part 4 via a second rotating shaft 7. 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 earphone sleeve 2 to rise and fall within the earphone receiving cavity 12.
[0090] Reference Figure 6 and Figure 7 After 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.
[0091] The rotating part 4 is fixed to the lid 3. (Refer to...) Figures 3-5 The rotating part 4 has a first shaft hole 41, a second shaft hole 42, and a spring positioning hole 43 arranged in parallel. The second shaft hole 42 is located between the first shaft hole 41 and the spring positioning hole 43. A third shaft hole 111 is provided at the opening of the accommodating cavity 11. The first rotating shaft 40 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 40, 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.
[0092] Reference Figure 5 One end of the arc-shaped connecting rod 521 is provided with a fourth shaft hole 51. The second rotating shaft 7 is inserted into the fourth shaft hole 51 and the second shaft hole 42, and the rotating part 4 can drive the arc-shaped connecting rod 521 to move based on the second rotating shaft 7. Preferably, two second shaft holes 42 are symmetrically provided, and after the arc-shaped connecting rod 521 is inserted between the two second shaft holes 42, the connection is achieved by inserting the second rotating shaft 7.
[0093] Reference Figure 5 The other end of the arc-shaped connecting rod 521 is provided with a fifth shaft hole 52. The third rotating shaft 8 is inserted into the fifth shaft hole 52 and the sliding groove 50, and the arc-shaped connecting rod 521 is slidably connected to the C-shaped connecting piece 522 based on the third rotating shaft 8 and the sliding groove 50.
[0094] In one embodiment, reference is made to... Figure 5The rotating part 4 has a rotating shaft block 45 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 45, and a second shaft hole 42 and a spring positioning hole 43 are provided on the rotating block 44. The rotating block 44 is rotatably connected to the arc-shaped connecting rod 521 via a second rotating shaft 7. The number of rotating blocks 44 is set according to the shape of the arc-shaped connecting rod 521 and the requirements, as shown in the reference. Figure 5 and Figure 24 .
[0095] In one implementation, refer to Figure 2 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.
[0096] 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.
[0097] Correspondingly, when the earphone sleeve includes two earphone trays 21, the lifting base plate 523 includes two lower connecting parts, which are respectively connected to both ends of the lifting base plate 523 and respectively connected to the two earphone trays 21 one-to-one. Preferably, the vertical connecting piece 524 is located in the middle of the middle connecting rod, and the two lower connecting parts are respectively connected to both ends of the middle connecting rod and respectively connected to the two earphone trays 21. That is, the earphone trays 21 are fixed on the second rod. The earphone trays 21 can be fixedly connected to the second rod by bolts, clips, or integral molding. In addition, the earphone trays 21 can also be integrally molded with the lower connecting parts.
[0098] Reference Figure 2 The lower inner shell 14 has an earphone receiving cavity 12, the bottom of which has a hollow structure, communicating with the receiving cavity 11 through the bottom hollow structure. The split design of the case body 1 is simple and reliable, facilitating the assembly of components such as the earphone sleeve 2 and the pushing component 5 into the receiving cavity 11, improving the aesthetics of the earphone charging case while enabling the earphone to rise and fall. Furthermore, the split design of the case body 1 improves the processing efficiency of the receiving cavity 11, reduces the production difficulty and cost of the case body 1, and simplifies the structure of the earphone charging case.
[0099] 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.
[0100] Reference Figure 4 and Figure 5 The earphone charging case also includes an elastic element 9 disposed within the receiving cavity 11. One end of the elastic element 9 is connected to the rotating part 4, and the other end is connected to the case body 1. When the earphone charging case is closed, the lid 3 can be securely closed onto the case body 1 under the tension of the elastic element 9. When the earphone charging case is open, the lid 3 can maintain its maximum opening angle under the tension of the elastic element 9.
[0101] Reference Figure 6 and Figure 7 The accommodating cavity 11 is provided with a spring movement space 113 and a spring connecting part 114, and the elastic element 9 is movably accommodated within the spring movement space 113. (Refer to...) Figure 8 and Figure 9 One end of the elastic element 9 is connected to the spring positioning hole 43, and the other end of the elastic element 9 is connected to the spring connecting part 114.
[0102] In this embodiment, the elastic element 9 is a spring, including a spring body 91. The spring body 91 is integrally connected to an elastic drive arm 92 and an elastic support arm 93, as shown in the figure. Figure 5 The spring body 91 is movably accommodated within the spring movement space 113, the elastic drive arm 92 is positioned on the spring positioning hole 43 of the rotating part 4, and the elastic support arm 93 is positioned on the spring connecting part 114 of the accommodating cavity 11.
[0103] The spring body 91 includes a first spring body and a second spring body that are symmetrical to each other. The elastic drive arm 92 includes a first elastic drive arm and a second elastic drive arm that are symmetrical to each other. The first elastic drive arm is integrally connected to the first spring body, and the second elastic drive arm is integrally connected to the second spring body. The elastic support arm 93 is a "U"-shaped elastic support arm. One end of the elastic support arm 93 is connected to the first spring body, and the other end of the elastic support arm 93 is connected to the second spring body. The middle part of the elastic support arm 93 extends downward and is positioned on the spring connection part 114 of the accommodating cavity 11.
[0104] Reference Figure 7 The spring connecting part 114 is disposed in the spring moving space 113. The spring connecting part 114 can be configured as a slot structure or a hole structure. The middle part of the elastic support arm 93 is engaged in the slot structure or hole structure. The first spring body and the second spring body are movably accommodated in the spring moving space 113.
[0105] Reference Figure 4 and Figure 5The rotating part 4 has two symmetrically arranged spring positioning holes 43. The ends of the first elastic drive arm and the second elastic drive arm are bent inwards towards each other to form spring positioning pins. The two spring positioning pins are parallel to the first rotating shaft 40 and are rotatably inserted into the corresponding spring positioning holes 43.
[0106] 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 earphone 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 earphone charging case 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 earphone charging case is shaken. The opening and closing process feels very smooth.
[0107] Reference Figure 10 and Figure 11 The earphone charging case also includes a conductive pin 10, a power supply, and a circuit board. The conductive pin 10 is fixed inside the earphone sleeve 2 and is used for electrical connection with the earphone inside the earphone sleeve 2. The power supply and 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 earphone sleeve 2, and is electrically connected to the conductive pin 10. Since the conductive pin 10 is fixed inside the earphone sleeve 2, it can rise and fall with the earphone sleeve 2, thus ensuring continuous charging when the earphone is raised or lowered. The earphone charging case also has 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.
[0108] In one embodiment, the earphone charging case further includes a first magnetic attachment and a second magnetic attachment. The first magnetic attachment is located at the end of the lid 3 away from the rotating part 4, and the second magnetic attachment is located at the end of the body 1 away from the rotating part 4. When the lid 3 and the body 1 are fastened together, the first and second magnetic attachments attract each other. Specifically, both the first and second magnetic attachments are magnets and are magnetically attracted to each other. The arrangement of the first and second magnetic attachments provides a locking force when the lid 3 and the body 1 are fastened together to seal the earphone receiving cavity 12, reducing the risk of losing the earphones due to accidental opening of the lid 3 and improving the earphone charging case's ability to protect the earphones.
[0109] 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, accommodating 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 case and reducing the size and weight of the earphone charging case.
[0110] In this embodiment, the lid is rotatably connected to the case body via a rotating part. The earphone sleeve is slidably connected within the earphone housing cavity. The pushing component is disposed within the housing cavity and movably positioned within a blocking groove. One end of the pushing component is rotatably connected to the rotating part, while the other end is fixedly connected to the earphone sleeve. When the lid rotates to open and close relative to the case body, the rotating part drives the pushing component to move up and down within the blocking groove, thereby causing the earphone sleeve to slide up and down within the earphone housing cavity, raising and lowering the earphone. The blocking groove allows the pushing component to move longitudinally, preventing twisting of the pushing component during the opening and closing of the earphone charging case, which would affect the smoothness of the opening and closing process and improve user comfort.
[0111] Second embodiment:
[0112] This embodiment differs from the first embodiment in that the entire structure or partial structure of the pushing component 5, the blocking groove 13, the elastic element 9, and the rotating part 4 are different.
[0113] Reference Figure 12 and Figure 14The pushing component 5 includes an arc-shaped connector 541, a C-shaped connecting plate 542, a lifting connecting plate 543, and a snap-fit part 544. The arc-shaped connector 541 has a structure basically the same as the arc-shaped connecting rod 521 in the first embodiment, and the lifting connecting plate 543 has a structure basically the same as the lifting base plate 523 in the first embodiment, which will not be described again here. The C-shaped connecting plate 542 has horizontally extending sliding grooves 50 on its opposite sides. The other end of the arc-shaped connector 541 extends into the opening of the C-shaped connecting plate 542 and is movably connected to the sliding groove 50 via a third rotating shaft 8. One end of the arc-shaped connector 541 is rotatably connected to the rotating part 4 via a second rotating shaft 7. The opening orientation of the C-shaped connecting plate 542 can be set according to requirements; in this embodiment, the opening is oriented upwards. The lifting connecting plate 543 is connected below the C-shaped connecting plate 542, and its end is fixedly connected to the earphone sleeve 2. Specifically, the C-shaped connecting plate 542 is provided with mounting holes, and the lifting connecting plate 543 is installed in the mounting holes, with both ends of the lifting connecting plate 543 extending to both sides and being fixedly connected to the earphone sleeve 2 respectively. The snap-fit part 544 is connected to the side of the C-shaped connecting plate 542 facing the blocking groove 13. The two sides of the snap-fit part 544 extend from both sides of the C-shaped connecting plate 542.
[0114] Reference Figure 17 Two L-shaped plates 17 are symmetrically arranged on the inner wall of the lower outer shell 15. A blocking groove 13 is formed between the two L-shaped plates 17 and the inner wall of the lower outer shell 15, and the blocking groove 13 has a lateral opening. Specifically, the first part of each of the two L-shaped plates 17 is parallel to the inner wall of the lower outer shell 15, and the second part of each of the two L-shaped plates 17 is perpendicular to the inner wall of the lower outer shell 15. There is a certain distance between the first parts of the two L-shaped plates 17. Thus, a blocking groove 13 with a lateral opening is formed between the two L-shaped plates 17 and the inner wall of the lower outer shell 15. The width of the lateral opening is smaller than the width of the blocking groove 13.
[0115] When the pushing component 5 is placed inside the accommodating cavity, the snap-fit part 544 is slidably connected to the blocking groove 13, and the C-shaped connecting plate 542 is located outside the blocking groove 13. The C-shaped connecting plate 542, slidably connected to the blocking groove 13 via the snap-fit part 544, can achieve horizontal limitation in the left-right and front-back directions with the charging box body 1, ensuring that the C-shaped connecting plate 542 and the lifting connecting plate 543 can only move up and down within the accommodating cavity, preventing torsion from affecting opening, closing, and lifting. In this embodiment, the horizontal limitation of the C-shaped connecting plate 542 in the left-right and front-back directions can also be achieved by using a vertical connecting piece 524 as in the first embodiment. A longitudinally penetrating blocking groove 13 is provided inside the accommodating cavity 11, and the vertical connecting piece 524 is moved within the blocking groove 13 to achieve lateral movement limitation.
[0116] Reference Figure 15 and Figure 16The arc-shaped connector 541 is movably connected to the sliding groove 50 of the C-shaped connecting plate 542 via the third rotating shaft 8. The C-shaped connecting plate 542 is connected to the blocking groove 13 via the snap-fit part 544. This ensures that the arc-shaped connector 541 and the C-shaped connecting plate 542 can move horizontally relative to each other in the front-back direction. At the same time, it also ensures that the C-shaped connecting plate 542 can only move in the direction of gravity (vertical direction) without deflection. This improves the stability of the moving component 5 and ensures that the parts are stable and do not make any abnormal noise after the earphone charging case is dropped.
[0117] Reference Figure 13 The rotating part 4 has a first shaft hole 41 and a second shaft hole 42 arranged in parallel, and a plurality of communicating grooves 46 that are radially connected to the second shaft hole 42. Optionally, the rotating part 4 has three communicating grooves 46 that are radially connected to the second shaft hole 42. Specifically, a rotating shaft block 45 protrudes from the edge of the rotating part 4, the first shaft hole 41 and the second shaft hole 42 are disposed on the rotating shaft block 45, and a plurality of communicating grooves 46 that are radially connected to the second shaft hole 42 are disposed on the outer side of the rotating shaft block 45.
[0118] A third shaft hole 111 is provided at the opening of the accommodating cavity 11. A first rotating shaft 40 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 40, thereby realizing the rotational opening and closing of the box cover 3 and the box 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.
[0119] Reference Figure 14 One end of the arc-shaped connector 541 is provided with a fourth shaft hole 51. The arc-shaped connector 541 can extend into the connecting groove 46 located in the middle position. The second rotating shaft 7 is inserted into the fourth shaft hole 51 and the second shaft hole 42, connecting the arc-shaped connector 541 and the rotating part 4.
[0120] In this embodiment, the elastic element 9 differs from the elastic element 9 in the first embodiment in that the ends of the first and second elastic drive arms are similar to the structure of a spring body. The first and second elastic drive arms extend into the connecting grooves 46 located on both sides, respectively. The second rotating shaft 7 passes through the first and second elastic drive arms and is inserted into the fourth shaft hole 51 and the second shaft hole 42, thereby realizing both the connection between the arc-shaped connector 541 and the rotating part 4, and the connection between the rotating part 4 and the elastic element 9. (Refer to...) Figure 12 In addition, the rotating part 4 and the elastic element 9 can also be connected using the same structure as in the first embodiment.
[0121] In this embodiment, when the lid of the earphone charging case rotates to open and close relative to the case body, the rotating part drives the pushing component to move up and down within the blocking groove, thereby causing the earphone sleeve to slide up and down within the earphone receiving cavity to raise and lower the earphone. The blocking groove allows the pushing component to move longitudinally, preventing the pushing component from twisting during the opening and closing of the earphone charging case, which would affect the smoothness of the opening and closing and improve the user experience.
[0122] Third embodiment:
[0123] This embodiment differs from the first and second embodiments in that the structure of the driving component 5 is different. (Refer to...) Figure 18 and Figure 19 The pushing component 5 includes a fixed block 531, a sliding block 532, a damping element 533, a C-shaped connector 534, a lifting support plate 535, and a longitudinal connecting piece 536.
[0124] The fixed block 531 includes a moving groove 5311 and a clearance groove 5312. The moving groove 5311 is a horizontally extending groove with its opening facing the side where the rotating part 4 is located. The clearance groove 5312 is longitudinally connected to the moving groove 5311, and the width of the clearance groove 5312 is smaller than the width of the moving groove 5311. Figure 20 .
[0125] The sliding block 532 includes a mounting plate 5321, a movable plate 5322, and an extension plate 5323 connected sequentially from top to bottom, as shown in the figure. Figure 19 The mounting plate 5321 is horizontally positioned, with one end rotatably connected to the rotating part 4, and the other end movably connected within the moving groove 5311. The moving plate 5322 is vertically positioned and installed within the clearance groove 5312. The extension plate 5323 is located below the fixed block 531, and third rotating shafts 8 are provided on both sides of the extension plate 5323. A damping element 533 is connected between the mounting plate 5321 and the inner wall of the moving groove 5311. The fixed block 531 is located within the receiving cavity 11 and can move up and down with the sliding block 532. The damping element 533 can be used to drive the sliding block 532 to reset. The mounting plate 5321 is movably connected within the moving groove 5311 to provide guidance for the lateral movement of the sliding block 832 and to limit its lateral movement distance.
[0126] The C-shaped connector 534 has arc-shaped sliding grooves 50 on both opposite sides, which curve downwards toward the outer side of the box body 1. That is, the end of the sliding groove 50 near the outer side of the box body 1 is lower than the end near the inner side of the box body 1. (Refer to...) Figure 18 and Figure 19The extension plate 5323 extends into the opening of the C-shaped connector 534 and is connected to the sliding groove 50 via the third rotating shaft 8. The sliding block 532 slides within the sliding groove 50 via the third rotating shaft 8, enabling the axial rotational force to move the sliding block 532 relative to the C-shaped connector 534 when the rotating part 4 flips, preventing jamming. The lifting plate 535 is connected to the C-shaped connector 534, and the end of the lifting plate 535 is fixedly connected to the earphone sleeve 2. One end of the longitudinal connecting piece 536 is connected to the C-shaped connector 534, and the other end of the longitudinal connecting piece 536 extends below the lifting plate 535.
[0127] In this embodiment, the blocking groove 13 is configured in the same way as in the first embodiment, and will not be described again. The longitudinal connecting piece 536 can be movably connected within the blocking groove 13, thereby allowing the lifting plate 535 and the C-shaped connector 534 to move only up and down along the direction of gravity, avoiding twisting, jamming, or other situations. Alternatively, the longitudinal connecting piece 536 can also be connected between the C-shaped connector 534 and the lifting plate 535, as in the first embodiment. Optionally, the C-shaped connector 534 can also be limited by providing a snap-fit portion and a blocking groove as in the second embodiment.
[0128] In this embodiment, the opening of the C-shaped connector 534 faces upward. The lifting plate 535 consists of two parts, which are respectively connected to both sides of the C-shaped connector 534, as shown in the figure. Figure 18 and Figure 19 .
[0129] Because the cover 3 provides an inclined axial rotational force when it flips open and closes, this rotational force is decomposed into a force in the direction of gravity and a lateral force in the front-back direction (the lateral force is perpendicular to the first rotating shaft 40), causing the sliding block 532 to move in both the front-back and gravity directions. Under the force of gravity, the sliding block 532 will move downward or upward; under the lateral force in the front-back direction, the sliding block 532 will move forward or backward; the sliding block 532 drives the third rotating shaft 8 to slide within the sliding groove 50, thereby pushing the C-shaped connector 534 and the lifting plate 535 to move up and down, realizing the lifting and lowering of the earphone sleeve 2.
[0130] In this embodiment, the structure of the elastic element 9 and the rotating part 4 can adopt the structure of the elastic element 9 and the rotating part 4 in the first embodiment or the second embodiment, which will not be described again here.
[0131] In this embodiment, the lid is rotatably connected to the case body via a rotating part. The earphone sleeve is slidably connected within the earphone housing cavity. The pushing component is disposed within the housing cavity and movably positioned within a blocking groove. One end of the pushing component is rotatably connected to the rotating part, while the other end is fixedly connected to the earphone sleeve. When the lid rotates to open and close relative to the case body, the rotating part drives the pushing component to move up and down within the blocking groove, thereby causing the earphone sleeve to slide up and down within the earphone housing cavity, raising and lowering the earphone. The blocking groove allows the pushing component to move longitudinally, preventing twisting of the pushing component during the opening and closing of the earphone charging case, which would affect the smoothness of the opening and closing process and improve user comfort.
[0132] Fourth embodiment:
[0133] This embodiment differs from the three embodiments described above in that the structures of the pushing component 5 and the blocking groove 13 are different. (Refer to...) Figure 24 and Figure 25 The actuating component 5 includes a connecting rod 511, a lifting shaft 512, a lifting base 513, and a connector 514. One end of the connecting rod 511 (near the top) is movably connected to the rotating part 4, and the other end of the connecting rod 511 (near the bottom) is movably connected to one end of the lifting shaft 512 (the top). The other end of the lifting shaft 512 (the bottom) is movably connected to the lifting base 513, and the end of the lifting base 513 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 511, the lifting shaft 512, and the lifting base 513 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.
[0134] Reference Figure 22 and Figure 23 When 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 40). Under the force f1 in the direction of gravity, the lifting shaft 512 will move downward or upward; under the lateral force f2 in the front-back direction, the lifting shaft 512 will move forward or backward and tilt. Since the lifting shaft 512 is movably connected to the connecting rod 511 and the lifting base 513, the connecting rod 511, the lifting shaft 512, and the lifting base 513 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 earphone charging case and the raising and lowering of the earphones, improving the user experience.
[0135] Specifically, the top end of connecting rod 511 is rotatably connected to rotating part 4 via second rotating shaft 7, and the bottom end of connecting rod 511 is rotatably connected to the top end of lifting shaft 512 via third rotating shaft 8. Both second rotating shaft 7 and third rotating shaft 8 are arranged parallel to first rotating shaft 40, as shown in the reference section. Figure 24 and Figure 25 .
[0136] Reference Figure 25 and Figure 21 The other end (i.e., the bottom end) of the lifting shaft 512 is provided with a groove, and the surface of the lifting base 513 is provided with a protrusion. The connecting piece 514 passes through the protrusion and the groove sequentially from bottom to top and connects to the lifting shaft 512, thereby connecting the lifting base 513 to the bottom of the lifting shaft 512. (Refer to...) Figure 22 and Figure 23 After the connector 514 connects the lifting base 513 and the lifting shaft 512, the protrusion on the lifting base 513 is located in the groove, and a movable space is formed between the protrusion and the groove, and a movable space is formed between the connector 514 and the protrusion, so that the protrusion can move or rotate at multiple angles relative to the connector 514. When the lid 3 is flipped open and closed, under the action of the axial rotational force F, the rotating part 4 drives the lifting shaft 512 to move up and down and back and forth laterally through the connecting rod 511. Since the lifting base 513 is restricted to only moving up and down, the back and forth lateral movement of the lifting shaft 512 can be converted into a back and forth tilting movement. The movable space between the protrusion and the groove, and the movable space between the connector 514 and the protrusion, allows the lifting shaft 512 to complete the back and forth tilting movement requirements, thereby avoiding problems such as jamming during opening and closing.
[0137] In a preferred embodiment, the groove is configured as a downward-opening spherical groove 5121, and the protrusion is a spherical protrusion 5131. This ensures that the contact between the protrusion and the groove is a spherical-to-spherical fit, facilitating the tilting movement of the lifting shaft 512. It should be noted that the spherical groove 5121 and the spherical protrusion 5131 refer to spherical structures less than or equal to a hemisphere. Besides this, the groove and protrusion can also be configured with other shapes, as long as they meet the requirements for forward and backward tilting.
[0138] Reference Figure 25 The lifting base 513 is also provided with a through hole 5132, a longitudinally penetrating protrusion. (See reference...) Figure 21 The lifting shaft 512 is also provided with a connecting hole 5122, which is perpendicularly connected to the groove. (See reference...) Figure 25 The connector 514 includes a connecting end 5141 and a connecting rod portion 5142. The lateral dimension of the connecting end 5141 is larger than the diameter of the through hole 5132, and the diameter of the connecting rod portion 5142 is smaller than the diameter of the through hole 5132. The diameter of the connecting rod portion 5142 matches the size of the connecting hole 5122. (Refer to...) Figure 22 and Figure 23The connecting rod portion 5142 passes through the through hole 5132 from bottom to top and connects to the connecting hole 5122, thereby movably connecting the lifting base 513 and the lifting shaft 512. The distance between the groove and the connecting end 5141 is greater than the thickness of the protrusion, creating a space between the protrusion and the groove to facilitate relative tilting movement. The diameter of the connecting rod portion 5142 is smaller than the diameter of the through hole 5132, allowing the connecting rod portion 5142 to tilt within the through hole 5132, thus enabling the lifting shaft 512 to drive the connecting member 514 to tilt back and forth.
[0139] Optionally, the connecting rod portion 5142 is provided with an external thread, and the connecting hole 5122 is provided with an internal thread, and the two are connected by threads. The size of the movable space can be determined by the length of the connecting rod portion 5142 extending into the connecting hole 5122.
[0140] In this embodiment, the blocking groove 13 is provided on the side of the lower inner shell 14 near the rotating part 4, and is formed by a recess. The blocking groove 13 has a lateral opening, which faces the outside of the box body 1 in the front-rear direction. The lifting shaft 512 is longitudinally movable within the blocking groove 13, as shown in the figure. Figure 22 and Figure 23 The blocking groove 13 restricts the lifting shaft 512 to move only in the direction of gravity and the front-back direction, preventing it from tilting or deflecting to the left or right. This ensures the stability of the up-and-down movement of the earphone sleeve 2 and prevents the pushing component 5 from jamming. Preferably, the width of the blocking groove 13 is adapted to the maximum size of the lifting shaft 512 or the connection between the lifting shaft 512 and the connecting rod 511.
[0141] Reference Figure 25 The connecting rod 511 includes a connecting body 5111 and a first connecting arm 5112. Two first connecting arms 5112 extend parallel to each other on the top outer side of the connecting body 5111, and each of the two first connecting arms 5112 has a coaxial fourth shaft hole 51. A rotating block 44 can be inserted between the two first connecting arms 5112, and a second rotating shaft 7 is inserted into the two fourth shaft holes 51 and the two second shaft holes 42 to connect the connecting rod 511 and the rotating block 44. Optionally, the edge of the rotating shaft block 45 has two spaced rotating blocks 44 protruding from it, and each of the two rotating blocks 44 has a coaxial second shaft hole 42.

[0145] The structures of components not described in detail in this embodiment are the same as those of the corresponding components in the first, second, and third embodiments, and will not be described in detail again.
[0146] The earphone charging case of this embodiment includes a case body, an earphone sleeve, a case lid, and a pushing component. The case lid is rotatably connected to the case body via a rotating part. The earphone sleeve is slidably connected to the earphone receiving cavity longitudinally. The pushing component is disposed in the receiving cavity. One end of a connecting rod is movably connected to the rotating part, and the other end of the connecting rod is movably connected to one end of a lifting shaft. A connecting piece passes through the protrusion of the lifting base and the groove of the lifting shaft in sequence and is connected to the lifting shaft. The protrusion is movably connected in the groove. When the case lid rotates to open and close relative to the case body, the rotating part drives the lifting shaft to rise and fall via the connecting rod, thereby driving the lifting base and earphone sleeve to rise and fall. This can realize the earphone lifting and fall and prevent the pushing component from getting stuck when the earphone is lifted and fallen, ensuring the smoothness of the earphone lifting and fall and improving the user experience comfort.
