Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a headphone charging case and headphone kit. Background Technology

[0002] Wireless Bluetooth headphones, such as OWS (Open Wearable Stereo) headphones, are widely used due to their small size, portability, and lack of tangled wires. Wireless Bluetooth headphones typically have small battery capacities and are usually used with a charging case.

[0003] Typically, an earphone charging case consists of two parts: a body and a lid. The body and lid are connected on one side by a hinge, and on the other side by a latch. The body and lid together form an earphone compartment that matches the shape of the earphones, securing and housing them. When the earphones are inside the earphone compartment, the charging case charges them.

[0004] However, after manually flipping the lid to take out or put in the earphones, you still need to manually close the lid, which is cumbersome. Utility Model Content

[0005] This application provides an earphone charging case and earphone kit to improve the convenience of taking earphones out of and out of the earphone charging case.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] The first aspect of this application provides an earphone charging case, comprising:

[0008] Compared with the prior art, the earphone charging case provided in the first aspect of this application has the following advantages:

[0009] The earphone charging case provided in this application includes:

[0011] An earphone housing is located within the receiving cavity; the earphone housing is configured to rotatably engage with the outer shell; the earphone housing is configured to form an earphone cavity with a second opening for accommodating earphones;

[0012] A switch assembly includes a pressing member and an elastic member, wherein the pressing member is movablely engaged with the mounting hole along a first linear direction, and the pressing member passes through the mounting hole and is connected to the earphone housing, and the elastic member is disposed between the pressing member and the earphone housing;

[0013] When the pressing member is subjected to pressing force toward the earphone compartment, it causes the earphone compartment to rotate relative to the outer shell along the first rotation direction, so that the earphone compartment is in an open position where the second opening is opposite to the first opening; the pressing member moves toward the earphone compartment along the first straight direction, and causes the elastic member to elastically deform along the first straight direction and the first rotation direction;

The elastic member is disposed between the pressing member and the earphone compartment. When the pressing member is subjected to pressing force toward the earphone compartment, it converts the linear motion into rotation of the earphone compartment along a first rotational direction, causing the earphone compartment to rotate from a closed position to an open position. At the same time, the elastic member elastically deforms in the first linear direction and the first rotation. When the pressing member releases the pressing force, the elastic member restores its deformation along the first linear direction, causing the pressing member to move in the opposite direction and restore its deformation along the first rotational direction, causing the earphone compartment to rotate in the opposite direction of the first rotational direction, automatically returning from the open position to the closed position. The earphone charging case of this application embodiment only requires one hand to press the pressing part and the other hand to take out and put in the earphones, which is simple and convenient to operate; moreover, the elastic force of the elastic element realizes the automatic closing of the earphone case, eliminating the need for an additional closing operation of the earphone case, further simplifying the operation of taking out and putting in the earphones.

[0063] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0064] Typically, an earphone charging case consists of two parts: a body and a lid. The body and lid are connected on one side by a hinge, and on the other side by a latch. The body and lid together form an earphone compartment that matches the shape of the earphones, securing and housing them. When the earphones are inside the earphone compartment, the charging case charges them.

[0065] When you need to retrieve the earbuds, you have to hold the charging case with one hand, open the lid with the other, take out the earbuds, and then turn the lid to close the charging case. This process requires four steps, making the process cumbersome and resulting in a poor user experience. Moreover, the method of opening and retrieving the earbuds is monotonous, relying on a snap-fit ​​mechanism for feedback, which lacks interactivity.

[0066] In view of this, this application provides an earphone charging case, wherein the earphone compartment, which houses the earphones, is rotatably mounted inside the outer shell of the charging case; a switch assembly is provided between the earphone compartment and the charging case, and pressing the switch assembly causes the earphone compartment to rotate relative to the outer shell between an open position and a closed position, thereby opening and closing the earphone compartment. During this process, one hand presses the switch assembly while the other hand removes or places the earphones, requiring only two steps, making the operation simple, convenient, and improving the user experience.

[0067] Furthermore, the switch assembly features a spring-loaded component. The spring force of this component automatically rotates the earphone case from the open position to the closed position, eliminating the need for additional operation and further simplifying the earphone placement and removal process. Moreover, the push-button mechanical transmission structure offers greater playability and enhances the user experience.

[0068] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0069] Reference Figures 1 to 5 This application provides an earphone charging case, which includes: a shell 100, which constitutes the exterior of the earphone charging case. The shell 100 is configured to form a receiving cavity 110 with a first opening 101.

[0070] The outer shell 100 may include two half-shells, which are fixedly connected to form a receiving cavity 110, facilitating processing and molding.

[0071] The outer casing 100 can be like Figure 1 The outer shell 100 shown is ellipsoidal, but it can also be cylindrical or other shapes. The embodiments of this application do not limit the shape of the outer shell 100.

[0072] The earphone charging case may also include an earphone compartment 200 located within a receiving cavity 110. The earphone compartment 200 is configured to form an earphone cavity 210 with a second opening 201 for receiving earphones.

[0073] The headphone housing 200 has an open position and a closed position. In the closed position, the first opening 101 and the second opening 201 are offset, and the headphones 400 inside the headphone cavity 210 are not exposed. Figure 1 As shown; in the open position, the first opening 101 and the second opening 201 are opposite each other. The earphone cavity 210 can be exposed through the second opening 201 and the first opening 101, allowing the earphone 400 inside the earphone cavity 210 to be exposed, thus enabling the earphone 400 to be placed and removed. Figure 2 As shown.

[0074] The earphone compartment 200 rotates with the outer shell 100, and the earphone compartment 200 can rotate between the open and closed positions to allow the earphones 400 to be put in and taken out.

[0075] Continue to refer to Figure 1 and Figure 2 The earphone charging case may also include a switch assembly 300 configured to drive the earphone housing 200 to rotate relative to the housing 100 between an open position and a closed position.

[0076] The housing 100 is configured to form a mounting hole 120, which communicates with the receiving cavity 110. The switch assembly 300 is mounted in the mounting hole 120 and connected to the headphone compartment 200.

[0077] like Figure 3 and Figure 4 As shown, when the earphone case 200 is in the closed position, the switch assembly 300 does not protrude beyond the extension surface of the outer surface of the outer shell 100 from the outer surface of the elastic member 320. When the outer surface of the outer shell 100 where the switch assembly 300 is located is an arc surface, the outer surface of the switch assembly 300 is also an arc surface, and the radius of this arc surface is consistent with the radius of the arc surface of the outer shell 100. It can be understood that the outer surface of the outer shell 100 and the outer surface of the switch assembly 300 combine to form a smooth outer surface, making the other outer surfaces of the outer shell 100, except for the first opening 101, smooth outer surfaces. This design not only improves the neatness and aesthetics of the earphone charging case, but also reduces the probability of accidental opening caused by excessive protrusion of the switch assembly 300.

[0078] Combination Figure 2 When the headphone compartment 200 is in the open position, the outer surface of the switch assembly 300 away from the elastic member 320 is recessed relative to the outer surface of the housing 100, so that the outer surface of the switch assembly 300 is located inside the mounting hole 120, giving the switch assembly 300 sufficient travel, thereby ensuring the smooth operation of the headphone compartment 200.

[0079] Reference Figure 4 and Figure 5 The headphone compartment 200 has an outer surface facing the outer shell 100. When the headphone compartment 200 is in the closed position, the outer surface of the headphone compartment 200 opposite to the first opening 101 is located inside the extension of the outer surface of the outer shell 100, so that the headphone compartment 200 can rotate within the outer shell 100, avoiding the interference of the rotation of the headphone compartment 200 with the outward protrusion of some structures.

[0080] Continue to refer to Figure 2 In some embodiments of this application, the headphone housing 200 has two headphone cavities 210 arranged side by side along a first straight line direction, the first straight line direction corresponding to Figure 3The X-axis direction in the diagram. This setting facilitates the simultaneous placement and removal of both earphones (400).

[0081] Wherein, the maximum dimension of the first opening 101 along the first straight line direction is greater than the maximum dimension along the second straight line direction, such as Figure 3 As shown, the direction of the second straight line corresponds to Figure 3 In the Y-axis direction, the first opening 101 is an elongated hole extending along the first straight line direction.

[0082] Wherein, the maximum dimension of the second opening 201 along the first straight line direction is greater than the maximum dimension along the second straight line direction, so that the second opening 201 is an elongated hole extending along the first straight line direction.

[0083] The shape of the second opening 201 is the same as that of the first opening 101, which facilitates the taking out and putting in the earphones.

[0084] The maximum dimension of the housing 100 along the first straight line direction is greater than the maximum dimension along the second straight line direction, so as to provide sufficient space in the first straight line direction for mounting the headphone compartment 200.

[0085] In some embodiments, a switch assembly 300 is provided at one end of the housing 100 and the headphone compartment 200 along a first linear direction, and the other end is rotatably engaged. By operating the switch assembly 300, the headphone compartment 200 can rotate between an open position and a closed position.

[0086] In other embodiments, a switch assembly 300 is provided at each end of the housing 100 and the headphone compartment 200 along a first straight line. By operating one of the switch assemblies 300, or by operating both switch assemblies 300 simultaneously, the headphone compartment 200 is rotated from the closed position to the open position.

[0087] When the two switch components 300 are operated to open the headphone compartment 200, the two ends of the headphone compartment 200 along the first straight line are respectively subjected to rotational force, making the rotation of the headphone compartment 200 smoother.

[0088] Two switch assemblies 300 are respectively disposed at both ends of the housing 100 along the first straight direction. The outer surfaces of the housing 100 at both ends along the first straight direction have a small radius of curvature and a large degree of bending, making it easier for users to find the position of the switch assembly 300 and improving the convenience of opening and closing the earphone charging case.

[0089] Reference Figure 6 The switch assembly 300 includes a pressing member 310 and an elastic member 320. The pressing member 310 moves and engages with the mounting hole 120 along a first linear direction, and the pressing member 310 passes through the mounting hole 120 and connects to the earphone compartment 200. The elastic member 320 is disposed between the pressing member 310 and the earphone compartment 200.

[0090] When the switch assembly 300 is in the closed position, that is, when no pressing force is applied to the pressing member 310, the outer surface of the pressing member 310 does not protrude from the extension surface of the outer surface of the housing 100, reducing the possibility of the pressing member 310 being accidentally triggered.

[0091] This can be understood as the pressing member 310 being able to move relative to the outer casing 100 along the first straight line direction, with no relative rotation between the pressing member 310 and the outer casing 100.

[0092] When the pressing member 310 receives a pressing force toward the headphone housing 200, it drives the headphone housing 200 along the first rotation direction (corresponding to...). Figure 6 The headphone compartment 200 rotates relative to the outer shell 100 in the RD direction to position the second opening 201 opposite to the first opening 101. (See reference for details.) Figure 7 and Figure 8 The pressing member 310 moves toward the headphone compartment 200 along the first straight line direction, and causes the elastic member 320 to elastically deform along the first straight line direction and the first rotation direction.

[0093] When the pressing member 310 releases the pressing pressure towards the headphone compartment 200, the elastic member 320 restores its deformation, causing the pressing member 310 to move away from the headphone compartment 200, and causing the headphone compartment 200 to rotate relative to the outer shell 100 in the opposite direction of the first rotation direction, so that the headphone compartment 200 is in the closed position where the second switch is offset from the first opening 101.

[0094] In this embodiment of the application, the pressing member 310 is a component that applies pressing pressure to the user. Through the connection between the pressing member 310 and the headphone case 200, the pressing pressure is converted into the rotational force of the headphone case 200, driving the headphone case 200 to rotate from the closed position to the open position.

[0095] It should be noted that the pressing force refers to the pressure applied by the user to the pressing member 310, and has a target value. The pressing force applied by the user is not less than the target value, so as to drive the earphone case 200 to rotate in the first rotation direction, and cause the pressing member 310 to move towards the earphone case 200 in the first straight line direction, thereby causing the elastic member 320 to elastically deform in the first straight line direction and the first rotation direction.

[0096] The conversion of the pressing force of the pressing member 310 into rotational force, that is, the conversion of linear motion into rotational motion, can be achieved in various ways. For example, a guide mechanism can be provided between the pressing member 310 and the earphone housing 200 to convert linear motion into rotational motion. Another example is the use of an eccentric wheel or cam between the pressing member 310 and the earphone housing 200 to achieve the conversion of linear motion into rotational motion.

[0097] In this embodiment, the elastic element 320 is compressed by the pressing member 310 during the opening of the headphone compartment 200, and elastically deforms along the first linear direction. Because the headphone compartment 200 rotates relative to the outer shell 100 under the action of the pressing member 310, the elastic element 320 elastically deforms along the first rotational direction. It can be understood that when the headphone compartment 200 is in the open position, the elastic element 320 is not only axially compressed, but also elastically deformed circumferentially.

[0098] During the closing process of the headphone compartment 200, as the pressing member 310 loses its pressing force, the elastic member 320 recovers its deformation along the first linear direction, causing the pressing member 310 to move in the opposite direction; and the elastic member 320 recovers its deformation in the opposite direction of the first rotation direction, thereby causing the headphone compartment 200 to rotate in the opposite direction of the first rotation direction, from the open position to the closed position.

[0099] When the earphone charging case is provided with two switch components 300, the pressing member 310 of at least one of the switch components 300 is subjected to pressing force toward the earphone compartment 200, causing the earphone compartment 200 to rotate from the closed position to the open position.

[0100] When one of the pressing parts 310 is pressed, the rotation of the headphone housing 200 causes the switch assembly 300 on the other side to operate. When both pressing parts 310 are pressed simultaneously, the pressing directions of the two pressing parts 310 are opposite, so that the headphone housing 200 is subjected to two pressing forces at the same time, thereby making the rotation of the headphone housing 200 smoother.

[0101] With the above-described configuration, the headphone charging case of this embodiment provides a headphone cavity 210 for placing headphones by providing a headphone compartment 200, and a housing 100 for accommodating and mounting the headphone compartment 200. A switch assembly 300 is provided between the housing 100 and the headphone compartment 200 to enable the switching operation of the headphone compartment 200. The switch assembly 300 includes a pressing member 310 and an elastic member 320. The pressing member 310 moves and engages with the mounting hole 120 of the housing 100 along a first linear direction and is connected to the headphone compartment 200 through the mounting hole 120. The elastic member 320 is disposed between the pressing member 310 and the headphone compartment 200. When the pressing member 310 is subjected to pressing force towards the earphone compartment 200, the linear motion is converted into rotation of the earphone compartment 200 along the first rotation direction, causing the earphone compartment 200 to rotate from the closed position to the open position. At the same time, the elastic member 320 elastically deforms in the first linear direction and the first rotation. When the pressing member 310 is released, the elastic member 320 restores its deformation along the first linear direction, causing the pressing member 310 to move in the opposite direction, and restores its deformation along the first rotation direction, causing the earphone compartment 200 to rotate in the opposite direction of the first rotation direction, automatically returning from the open position to the closed position. The earphone charging case of this embodiment only requires one hand to press the pressing member 310 and the other hand to take out and put in the earphones 400, which is simple and convenient to operate. Moreover, the elastic force of the elastic member 320 is used to realize the automatic closing of the earphone compartment 200, eliminating the need for an additional closing operation of the earphone compartment 200, further simplifying the taking out and putting in the earphones 400.

[0102] Continue to refer to Figure 6 In this embodiment, a first guide rail 330 is provided at the end of the pressing member 310 facing the earphone compartment 200, and a second guide rail 220 is provided at the end of the earphone compartment 200 facing the pressing member 310. Through the cooperation of the first guide rail 330 and the second guide rail 220, the linear motion of the pressing member 310 is converted into the rotational motion of the earphone compartment 200. This not only results in a simple structure, but the mechanical transmission structure also increases playability and improves the user experience.

[0103] Reference Figure 9 The first guide rail 330 is an arc-shaped guide rail extending along a first rotation direction; the end of the first guide rail 330 opposite to the pressing member 310 forms a first guide surface 331. Along the first rotation direction, the distance between the first guide surface 331 and the pressing member 310 along a first linear direction decreases. This can be understood as the axial dimension of the portion of the first guide rail 330 with the first guide surface 331 decreasing along the first rotation direction. Along the extending direction of the first guide surface 331, the first guide surface 331 has a first end and a second end, with the first end closer to the pressing member 310 than the second end.

[0104] Reference Figure 10The second guide rail 220 is an arc-shaped guide rail extending along the first rotation direction; the end of the second guide rail 220 opposite to the headphone housing 200 forms a second guide surface 221. Along the first rotation direction, the distance between the second guide surface 221 and the headphone housing 200 increases along the first linear direction. This can be understood as the axial dimension of the portion of the second guide rail 220 with the second guide surface 221 increasing along the first rotation direction. Along the extension direction of the second guide surface 221, the second guide surface 221 has a first end and a second end, with the first end closer to the headphone housing 200 than the second end.

[0105] In some embodiments, the first guide surface 331 and the second guide surface 221 are inclined surfaces, which have a simple structure and are easy to process and implement.

[0106] In other embodiments, the first guide surface 331 and the second guide surface 221 are helical surfaces, which makes the relative movement between the first guide rail 330 and the second guide rail 220 continuous and smooth, thereby making the rotation of the headphone housing 200 continuous and smooth, and making it easier to switch on and off.

[0107] Thus, when the pressing member 310 is subjected to pressing force toward the headphone compartment 200, the second guide surface 221 abuts against the first guide surface 331, thereby causing the headphone compartment 200 to rotate relative to the outer shell 100 in the first rotation direction.

[0108] Along the extending direction of the first guide surface 331, the first guide surface 331 has a first end and a second end, with the first end closer to the pressing member 310 relative to the second end. Along the extending direction of the second guide surface 221, the second guide surface 221 has a first end and a second end, with the first end closer to the earphone housing 200 relative to the second end. When the earphone housing 200 is in the closed position, the second end of the first guide surface 331 is closer to the second end of the second guide surface 221; when the pressing member 310 is subjected to pressing force toward the earphone housing 200, the pressing member 310 moves toward the earphone housing 200 along a first linear direction, and the second end of the first guide surface 331 slides toward the first end of the second guide surface 221, while the second end of the second guide surface 221 slides toward the first end of the first guide surface 331. Due to the cooperation of the first guide surface 331 and the second guide surface 221, the earphone housing 200 rotates along a first rotation direction, rotating from the closed position to the open position.

[0109] In this embodiment, the first guide rail 330 and the second guide rail 220 between the pressing member 310 and the earphone compartment 200 utilize the inclined surfaces of the first guide rail 330 and the second guide rail 220 to convert the linear motion of the pressing member 310 into the rotational motion of the earphone compartment 200. The structure is simple and easy to implement; moreover, the mechanical transmission is not only stable and reliable, but also increases the playability.

[0110] In some embodiments of this application, a single first guide rail 330 may be provided, resulting in a simple structure. Correspondingly, a single second guide rail 220 may be provided.

[0111] In other embodiments of this application, multiple first guide rails 330 may be provided, and the multiple first guide rails 330 are arranged at intervals along a first rotation direction; the number of second guide rails 220 is the same as that of the first guide rails 330, and each second guide rail 220 cooperates with one of the first guide rails 330. The cooperation of multiple first guide rails 330 and second guide rails 220 increases the reliability and stability of the transmission between the pressing member 310 and the earphone housing 200.

[0112] In some specific embodiments, two first guide rails 330 are provided, and the two first guide rails 330 are evenly spaced along the first rotation direction; two second guide rails 220 are provided, and each second guide rail 220 mates with one of the first guide rails 330. Providing two first guide rails 330 and two second guide rails 220 can increase the stability of the transmission between the pressing member 310 and the earphone housing 200, avoid overly complex guide rail structures, and ensure that the first guide surface 331 and the second guide surface 221 have sufficient mating length.

[0113] The headphone case 200 rotates from the closed position to the open position by a certain angle. If this angle is too small, the second opening 201 of the headphone case 200 cannot be misaligned with the first opening 101, thus failing to achieve effective closure. In order to achieve misalignment between the second opening 201 and the first opening 101, the size of the first opening 101 and the second opening 201 may be too small, increasing the difficulty of taking the headphones 400 out and putting them in.

[0114] When the angle is too large, the rotation stroke of the headphone compartment 200 is large, resulting in a large pressing stroke of the pressing component 310, which not only increases the size of the structure but also increases the inconvenience of operation.

[0115] In some embodiments, the earphone case 200 rotates 90° from the closed position to the open position, which ensures that the second opening 201 is misaligned with the first opening 101 when the earphone case 200 is in the closed position, and also ensures that the earphone case 200 is easy to open and close. In addition, the first guide rail 330 and the second guide rail 220 do not need to have excessively large axial dimensions, making the structure of the switch assembly 300 compact and helping to ensure the overall aesthetics of the earphone charging case.

[0116] Of course, this is not a limitation on the rotation angle of the headphone housing 200. Those skilled in the art can determine the rotation angle of the headphone housing 200 based on the number of the first guide rail 330 and the second guide rail 220, the axial dimensions of the first guide rail 330 and the second guide rail 220, the pressing stroke of the pressing member 310, the external dimensions of the headphone housing 200 and the outer shell 100, and other sound velocity.

[0117] Continue to refer to Figure 9 The first guide rail 330 includes a first part and a second part, which are arranged and connected along a first rotation direction. The first part forms a first guide surface 331 opposite to the end face of the pressing member 310, and the second part forms a first plane 332 opposite to the end face of the pressing member 310. The first plane 332 is connected to the second end of the first guide surface 331. The second part enhances the structural strength of the first guide rail 330.

[0118] like Figure 10 As shown, the second guide rail 220 includes a third part and a fourth part, which are arranged and connected along a first rotation direction. The end face of the third part facing away from the headphone housing 200 forms a second guide surface 221, and the end face of the fourth part facing away from the headphone housing 200 forms a second plane 222. The second plane 222 is connected to the second end of the second guide surface 221. The fourth part enhances the structural strength of the second guide rail 220.

[0119] It should be noted that the gap between two adjacent first guide rails 330 can accommodate the fourth part of the second guide rail 220, and the gap between two adjacent second guide rails 220 can accommodate the second part of the first guide rail 330, so as to avoid the second part and the fourth part interfering with the rotation of the headphone compartment 200.

[0120] In some embodiments, when the headphone case 200 is in the open position, the second part is away from the side of the first part and abuts against the side of the fourth part on the side of its first rotation direction, thereby limiting the rotational travel of the headphone case 200.

[0121] In some embodiments, combined with Figure 9 The end of the pressing member 310 facing the headphone compartment 200 is constructed to form an annular cavity 311, which is circular.

[0122] The pressing member 310 is configured to form an outer ring wall and an inner ring wall, with a gap between the outer ring wall and the inner ring wall to form an annular cavity 311. The first guide rail 330 is located inside the inner ring wall.

[0123] Combination Figure 10 The headphone housing 200 has a protrusion 230 at one end facing the pressing member 310, and the protrusion 230 is configured to form a positioning groove 231. The protrusion 230 can be located on the outside of the second guide rail 220.

[0124] In some embodiments, combined with Figure 7 and Figure 8 The elastic element 320 can be a helical spring, with one end of the helical spring housed in the annular cavity 311; the other end of the helical spring is inserted into the positioning groove 231.

[0125] The positioning groove 231 can be an arc-shaped groove extending along the first rotation direction, so that the spring coil and the positioning groove 231 have a longer mating length, ensuring that the positioning groove 231 has a circumferential limiting effect on the helical spring.

[0126] The positioning groove 231 has an opening at one end along the circumferential direction, which facilitates the insertion of the spring coil into the positioning groove 231. Since the positioning groove 231 restricts the circumferential position of the helical spring, the end opening of the positioning groove 231 opposite to the headphone housing 200 along the first straight direction facilitates the engagement of the spring coil with the positioning groove 231 and also helps to reduce the processing difficulty of the positioning groove 231.

[0127] In some other embodiments, the elastic element 320 can be a torsion spring, which includes a helical spring portion 321 and a torsion arm portion 322. The spring coil ends at both ends of the helical spring portion 321 are respectively connected to the torsion arm portion 322. A portion of the helical spring portion 321 is accommodated in the annular cavity 311, and the torsion arm portion 322, which is away from the annular cavity 311, is inserted into the positioning groove 231.

[0128] By setting the elastic element 320 as a torsion spring, it can elastically deform along the axial direction of the helical spring part 321. Through the cooperation of the torsion arm part 322 and the positioning groove 231, the elastic deformation along the circumferential direction can be smoother, thereby enabling the elastic element 320 to drive the headphone compartment 200 to reset more smoothly.

[0129] In this embodiment, by constructing an annular cavity 311 in the pressing member 310 to accommodate one end of the helical spring, the axial deformation of the helical spring can also be guided; the earphone compartment 200 limits the circumferential position of the helical spring by setting the positioning groove 231, so that the helical spring can elastically deform along the circumferential direction.

[0130] Due to the pressing force of the pressing member 310, one end of the coil spring abuts against the pressing member 310, making it less likely that the end of the coil spring will rotate. Therefore, a circumferential limiting structure is not required, which helps to simplify the structure of the pressing member 310.

[0131] Combination Figure 11 In some embodiments of this application, a limiting member 121 is provided on the wall of the mounting hole 120, and the limiting member 121 is located at the end of the mounting hole 120 facing the headphone compartment 200. Combined with Figure 12 The limiting member 121 extends along the first rotation direction and has a first end and a second end along its extension direction; along the first rotation direction, a rotational interval 122 is formed between the first end and the second end of the limiting member 121.

[0132] Reference Figure 10The protrusion 230 rotatably engages with the rotation interval 122. This can be understood as the rotation interval 122 providing clearance for the protrusion 230 and providing rotational space for it. When the headphone compartment 200 is in the closed position, the protrusion 230 abuts against the first end of the limiting member 121; when the headphone compartment 200 is in the open position, the protrusion 230 abuts against the second end of the limiting member 121. By utilizing the abutment between the protrusion 230 and the limiting member 121, the closed and open positions of the headphone compartment 200 are limited, making the closed and open positions of the headphone compartment 200 more stable and reducing the possibility of the headphone compartment 200 being accidentally opened.

[0133] By providing an open annular limiting member 121 on the wall of the mounting hole 120, the protrusion 230 at the end of the headphone compartment 200 can be avoided, and the headphone compartment 200 can be limited by the contact between the limiting member 121 and the protrusion 230, making the closed and open positions of the headphone compartment 200 more stable and reducing the possibility of the headphone compartment 200 being accidentally opened.

[0134] Continue to refer to Figure 9 The pressing member 310 includes a pressing body 312 and a connecting arm 313, with the connecting arm 313 disposed on the side of the pressing body 312. When the cross-sectional shape of the pressing body 312 is circular, the connecting arm 313 is disposed on the peripheral side of the pressing body 312. The cross-section of the pressing body 312 is perpendicular to the first straight line direction.

[0135] Reference Figure 11 The mounting hole 120 has a mating groove 123 and a limiting stop 124 on its wall. The mating groove 123 extends along a first straight line direction. The limiting stop 124 is located at one end of the mating groove 123 away from the receiving cavity 110. The limiting stop 124 and the limiting member 121 are located at the two ends of the extending direction of the mating groove 123, respectively.

[0136] Along the first straight line direction, the pressing body 312 is movably engaged with the mounting hole 120, and the connecting arm 313 is movably engaged with the mating groove 123, providing a guiding function for the movement of the pressing member 310 along the first straight line direction.

[0137] Reference Figure 8 When the headphone compartment 200 is in the closed position, the connecting arm 313 abuts against the limiting stop 124 to restrict the connecting arm 313 within the mating groove 123 and prevent the pressing member 310 from coming out of the mounting hole 120.

[0138] The connecting arms 313 can be provided in multiple ways, and the multiple connecting arms 313 are arranged at intervals along the circumference of the pressing body 312; correspondingly, the mating grooves 123 are provided in multiple ways, and each mating groove 123 mates with one of the connecting arms 313; each mating groove 123 is provided with a limit member 121 at its outer end.

[0139] For example, two connecting arms 313 are provided, and the two connecting arms 313 are evenly spaced along the circumference of the pressing body 312. Correspondingly, two mating grooves 123 are provided.

[0140] By setting multiple connecting arms 313 and multiple mating grooves 123, the stability and balance of the fit between the pressing member 310 and the mounting hole 120 are improved.

[0141] An annular cavity 311 is provided at one end of the pressing body 312 facing the earphone compartment 200, so that the elastic element 320 is located between the pressing body 312 and the earphone compartment 200.

[0142] In this embodiment, the pressing member 310 is provided with a pressing body 312 that engages with the mounting hole 120, and a connecting arm 313 that engages with a mating groove 123 on the wall of the mounting hole 120, which provides guidance for the movement of the pressing member 310; by providing a limiting member 121 at the outer end of the mating groove 123, which abuts against the connecting arm 313, the pressing member 310 is restricted to the mounting hole 120 and does not detach.

[0143] Continue to refer to Figure 9 and Figure 10 One of the pressing member 310 and the earphone compartment 200 is provided with a shaft portion 314, and the other is provided with a bushing 240; the shaft portion 314 extends along a first straight line direction.

[0144] During the opening and closing of the headphone compartment 200, the shaft 314 and the bushing 240 rotate and engage, and the shaft 314 and the bushing 240 move along the axial direction of the shaft 314.

[0145] For example, the pressing body 312 of the pressing member 310 is provided with a shaft portion 314, which is located at the center of the plurality of first guide rails 330. A bushing 240 is provided in the earphone housing 200 and is located inside the plurality of second guide rails 220. The bushing 240 can be connected to the second guide rails 220 to improve the structural strength of the second guide rails 220.

[0146] In this embodiment of the application, the pressing member 310 and the earphone housing 200, through the cooperation of the shaft portion 314 and the bushing 240, can guide the rotation of the earphone housing 200 and the axial movement of the pressing member 310, making the relative movement between the pressing member 310 and the earphone housing 200 more stable.

[0147] Combination Figure 1 , Figure 2 as well as Figure 6 This application also provides an earphone kit, which includes: earphones 400 and the earphone charging case described in the above embodiment, wherein the earphones 400 are housed in the earphone cavity 210 of the earphone charging case.

[0148] The earphone 400 can be an OWS (Open Wearable Stereo) or a bone conduction earphone, etc. The earphones can be charged in the charging case.

[0149] like Figure 7 As shown, the earphone charging case also includes a charging port 130, which is located on the side of the outer shell 100 away from the first opening 101 to avoid interference between the charging cable and the opening and closing of the earphone compartment 200.
