Description

Technical Field

[0001] This application relates to the field of charging case technology, and in particular to an earphone charging case. Background Technology

[0002] In related technologies, existing earphone charging cases typically consist of a lid and a body, with a charging slot inside the body to house the earphones. When the lid is closed, the earphones are stored in the charging slot for charging. When the earphones are needed, the user opens the lid. However, due to the depth of the charging slot, the earphones remain deeply embedded after the lid is opened, often requiring the user to use their fingers to pry them out. This method is not only inconvenient but can also cause the earphones to slip out due to uneven pressure, resulting in damage. Utility Model Content

[0003] This application provides an earphone charging case, which aims to improve the structure of the earphone charging case so that the earphone body can be easily and quickly taken out when the earphone charging case is opened, thereby improving the user experience.

[0004] In a first aspect, embodiments of this application provide an earphone charging case, which includes a lid, a body, and an inner tray assembly. The body has a charging slot and a through-hole inside, with the through-hole located within the charging slot, which is used to accommodate the earphone body. The inner tray assembly is movably embedded in the through-hole and can reciprocate along the depth direction of the charging slot. The inner tray assembly is used to magnetically attract the earphone body. When the lid is closed, it applies pressure to the earphone body and moves the inner tray assembly along the depth direction of the slot. When the lid is open, the inner tray assembly can reset along a first direction and cause a portion of the earphone body to protrude from the charging slot, where the first direction is opposite to the depth direction of the slot.

[0005] In one embodiment, the earphone body includes an earphone stem and an earphone head, the earphone head protruding from one side of the earphone stem, and the charging slot includes:

[0006] The first groove is used to accommodate the headpiece; and

[0007] The second groove is connected to the first groove and extends along the length of the charging groove. The second groove is provided with the through opening and is used to accommodate at least a portion of the earphone stem.

[0008] In one embodiment, the housing includes:

[0009] The outer shell has an internal cavity and is rotatably connected to the box lid;

[0010] The charging compartment is embedded in the inner cavity and fixedly connected to the outer shell; and

[0011] A circuit board is embedded in the inner cavity and fixed to at least one of the outer shell and the charging compartment;

[0012] The charging slot and the through-hole are both located in the charging compartment, and the inner support assembly is elastically connected to the circuit board.

[0013] In one embodiment, the inner support assembly includes:

[0014] Inner support body;

[0015] A magnetic component, located in the inner tray body, is used to magnetically attract the earphone body; and

[0016] An elastic element is disposed between the inner support body and the circuit board.

[0017] In one embodiment, the inner support body has an assembly cavity inside, and the magnetic component is embedded in and fixed to the assembly cavity.

[0018] In one embodiment, the inner support body is provided with a limiting groove, the limiting groove having an opening facing the circuit board, one end of the elastic member being inserted into the limiting groove, and the other end abutting against the circuit board.

[0019] In one embodiment, the inner support body has a protrusion protruding towards the inside of the assembly cavity. The protrusion extends along the depth direction of the groove and abuts against the magnetic component, thereby forming a gap between the magnetic component and the cavity wall of the assembly cavity.

[0020] In one embodiment, the inner support body has a limiting protrusion that extends along the length of the charging slot and is used to abut against the edge of the through opening.

[0021] In one embodiment, the earphone charging case further includes:

[0022] Charging contacts are located on the inner tray assembly;

[0023] In one scenario, the lid is in the closed state, and the charging contacts are electrically connected to the circuit board; in another scenario, the lid is in the open state, and the charging contacts are separated from the circuit board.

[0024] In one embodiment, the inner tray body is provided with a charging port, and the charging contacts include:

[0025] A terminal body is inserted into the charging port, and one end of the terminal body near the circuit board extends out of the charging port to form a first end, the first end being used for electrical connection to the circuit board. The other end of the terminal body away from the circuit board extends out of the charging port to form a second end, the second end being used for electrical connection to the earphone body.

[0026] A fixing part protrudes from the periphery of the terminal body and is connected to the inner wall of the charging hole.

[0027] Based on the above embodiments, the earphone charging case proposed in this application has a charging slot and a through-hole inside the charging slot. An inner tray component is movably embedded in the through-hole, allowing it to move flexibly along the depth of the charging slot, and it can magnetically attract the earphone body. When the lid is closed, it applies pressure to the earphone body, causing the inner tray component to move along the depth of the slot, securing the earphone body within the charging slot for charging. When the lid is opened, the inner tray component, due to its movable nature, can reset in a first direction opposite to the depth of the slot, simultaneously causing part of the earphone body to protrude from the charging slot. In this way, users no longer need to use their fingers to pry open the charging slot to remove the earphones; they can easily remove them with a gentle lift, preventing the earphones from slipping and being damaged due to inconvenience, greatly improving the user experience.

[0036] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0038] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0039] 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. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Please refer to the specific details. Figure 1As shown, this application proposes an earphone charging case 100, which includes a lid 10, a body 20, and an inner tray assembly 30. The body 20 has a charging slot 21 and a through-hole 22 inside. The charging slot 21 serves as a storage and charging space for the earphones. The through-hole 22 is located within the charging slot 21. The inner tray assembly 30 is movably embedded in the through-hole 22 and can reciprocate along the depth of the charging slot 21. Furthermore, the inner tray assembly 30 can magnetically attract the earphones, ensuring reliable placement of the earphones within the charging case 100. In one embodiment, the earphone charging case 100 also includes a circuit board 50 and charging contacts 40. The circuit board 50 is disposed within the body 20, and the charging contacts 40 are located within the body 20 and exposed in the charging slot 21. After the earphones are placed in the charging slot 21, the charging contacts 40 electrically connect the circuit board 50 and the earphones to charge them.

[0042] During use, when the case lid 10 is in the closed state (meaning it is positioned on the case body 20), the lid 10 is in direct contact with the earphone body and applies pressure. This pressure is transmitted through the earphone body to the inner support assembly 30, causing the inner support assembly 30 to move downwards along the depth direction of the charging slot 21. During this process, the earphone body is pushed into the charging slot 21 as the inner support assembly 30 moves. At this point, the case lid 10 and the inner support assembly 30 work together to hold the earphone body securely, ensuring good contact between the earphone body and the charging contacts 40 in the charging slot 21 to meet charging requirements. When the user opens the case lid 10, i.e., when the case lid 10 is in the open state, the pressure applied to the earphone body disappears, and the inner support assembly 30 can return to its original position upwards along a first direction A, opposite to the depth direction of the slot.

[0043] Furthermore, in this embodiment, the inner earpiece assembly 30 also acts magnetically on the earphone body. Therefore, even if there are certain changes in speed and acceleration during the reset process of the inner earpiece assembly 30, the earphone body will not detach from the inner earpiece assembly 30 during the reset process because it is magnetically attracted by the inner earpiece assembly 30, and will move synchronously with the inner earpiece assembly 30. In this way, during the reset process, the inner earpiece assembly 30 drives the earphone body to finally move to a position that is more protruding from the charging slot 21 and easier to grasp. Users no longer need to insert their fingers into the charging slot 21 to pry it out with effort. This reduces the risk of the earphone body slipping and being damaged due to inconvenience in picking it up, greatly improves the convenience of product use, and helps to extend the service life of the earphone body.

[0044] In one implementation method, please refer to [specific details]. Figure 1The earphone body includes an earphone stem and an earphone head, wherein the earphone head is provided with a sound outlet responsible for transmitting sound to the user's ear canal. Further, the charging slot 21 includes a second slot 212 and a first slot 211 for accommodating the earphone head. The shape and size of the first slot 211 are adapted to the shape and size of the earphone head, allowing the earphone head to be stably housed within the first slot 211. The second slot 212 communicates with the first slot 211 and extends along the length L of the charging slot 21. The second slot 212 has a through opening 22, preferably located at the bottom of the second slot 212. The second slot 212 is used to accommodate at least a portion of the earphone stem, providing reliable support and positioning for the earphone body.

[0045] In one implementation method, please refer to the specific details. Figures 1 to 3 As shown, the housing 20 includes an outer shell 23 and a charging compartment 24. The outer shell 23 has an internal cavity, and one side of the outer shell 23 is rotatably connected to the lid 10 to achieve the opening and closing of the lid 10. In one embodiment, the outer shell 23 is rotatably connected to the lid 10 via a hinge structure. The charging compartment 24, as a key carrier for realizing the charging function of the earphone, is embedded in the internal cavity and fixedly connected to the outer shell 23. This fixed connection can be selected from at least one of the following connection methods: snap-fit ​​connection, screw connection, and tight fit. The charging slot 21 and the through-hole 22 are both provided in the charging compartment 24. The circuit board 50, as the core component for internal circuit control and signal transmission of the housing 20, is embedded in the internal cavity and fixedly connected to at least one of the outer shell 23 or the charging compartment 24. The inner support component 30 is elastically connected to the circuit board 50, allowing the inner support component 30 to reciprocate along the depth direction of the charging slot 21 within the through-hole 22.

[0046] In one implementation method, please refer to the specific details. Figure 2 and Figure 3As shown, the aforementioned inner holder assembly 30 includes an inner holder body 31, a magnetic element 32, and an elastic element 33. The elastic element 33 is preferably a spring. The inner holder body 31 serves as the basic frame of the inner holder assembly 30, its shape adapting to the through-hole 22, and it can be movably embedded inside the through-hole 22, enabling stable reciprocating movement in the depth direction of the charging slot 21. The inner holder body 31 is provided with an inner holder groove 38 that matches the shape and size of the earphone stem of the earphone body. When the inner holder body 31 is embedded in the through-hole 22, the inner holder groove 38 serves as part of the second slot 212, and together with the second slot 212, forms a complete and fitting storage space for the earphone stem. At least a portion of the earphone stem can be embedded in the inner holder groove 38, providing positioning and support for the earphone stem. Simultaneously, the magnetic element 32 is disposed on the inner holder body 31, and its magnetic attraction force can tightly engage with the earphone body. When the earphone is placed in the charging slot 21, the magnetic attraction of the magnetic component 32, together with the inner slot 38 of the inner tray body 31, can effectively overcome the displacement caused by external shaking or slight collision, ensuring the stability and reliability of the earphone during the charging process.

[0047] Furthermore, the elastic element 33 is disposed between the inner tray body 31 and the circuit board 50. The elastic deformation characteristics of the elastic element 33 provide power support and buffer protection for the movement of the inner tray assembly 30, achieving the purpose of elastic connection between the circuit board 50 and the inner tray assembly 30. When the lid 10 is closed, the pressure applied by the lid 10 to the earphone body is transmitted to the inner tray body 31 through the earphone body. Under the pressure, the elastic element 33 undergoes compression deformation, causing the inner tray body 31 to move along the depth direction of the charging slot 21, further securing the earphone body within the charging slot 21. When the lid 10 is opened, the elastic element 33 returns to its original shape, and the resulting elastic force pushes the inner tray body 31 back to its original position in the opposite direction to the depth direction of the slot, thereby causing part of the earphone body to protrude from the charging slot 21, making it easy for the user to remove.

[0048] In one implementation method, please refer to the specific details. Figures 2 to 5 As shown, the inner tray body 31 has an assembly cavity 34 inside, which matches the outer contour of the magnetic component 32, ensuring that the magnetic component 32 can be securely embedded in the assembly cavity 34. On the one hand, this ensures the relative positional accuracy between the magnetic component 32 and the earphone body, allowing the magnetic force generated by the magnetic component 32 to act precisely on the earphone body, enhancing the magnetic attraction effect; on the other hand, the assembly cavity 34 prevents the magnetic component 32 from being directly exposed to external impacts or wear, extending the service life of the magnetic component 32. In addition, the cooperative cooperation between the inner tray groove 38 and the magnetic component 32 in the assembly cavity 34 allows the earphone body to be further precisely positioned under the magnetic attraction of the magnetic component 32 after being embedded in the inner tray groove 38, thereby ensuring that the earphone body remains stable during charging, effectively improving the reliability and functionality of the earphone charging case 100.

[0049] Optionally, the inner tray body 31 is provided with an opening communicating with the assembly cavity 34. The opening preferably faces the circuit board 50. Since the opening faces away from the second groove 212, foreign objects (such as dust, debris, liquids, etc., which may affect the performance of the charging contacts) are less likely to enter between the magnetic component 32 and the inner wall of the assembly cavity 34. This effectively avoids problems such as displacement of the magnetic component 32 or wear of the cavity wall due to debris accumulation, and also improves the aesthetics of the earphone charging case 100. The opening can also be located on the side wall of the inner tray body 31. Here, "side wall" refers to the side wall of the charging groove 21 in the groove width direction. When the opening is located on the side wall, a dustproof baffle or sealing ring can be added at the opening to further prevent external impurities from entering the assembly cavity 34 from a physical perspective, while not affecting the normal assembly and magnetic force of the magnetic component 32.

[0050] In one implementation method, please refer to the specific details. Figure 4 and Figure 5 As shown, the inner support body 31 is provided with a limiting groove 35, which has an opening facing the circuit board 50. One end of the elastic member 33 is inserted into the limiting groove 35, and the other end abuts against the circuit board 50. Understandably, the limiting groove 35 is adapted to the shape and size of the elastic member 33, which not only provides precise installation positioning for the elastic member 33, but also restricts the degree of freedom of displacement of the elastic member 33 in the horizontal direction, ensuring that it always moves in and out along the depth direction of the charging slot 21.

[0051] In one embodiment, the limiting groove 35 can be connected to the assembly cavity 34 mentioned above. In this way, the end of the elastic member 33 inserted into the limiting groove 35 can directly abut against the magnetic member 32. Thus, the elastic member 33 can realize the reset function of the entire inner tray assembly 30, and can also firmly limit the magnetic member 32 in the assembly cavity 34. Of course, using the magnetic member 32 to assemble the elastic member 33 can also make the whole structure more compact. When the lid 10 opens and closes to drive the inner tray assembly 30 to move, the magnetic member 32 can help constrain the deformation direction of the elastic member 33 and improve the accuracy of the movement of the inner tray assembly 30. The elastic member 33 can also be selected to abut against the inner tray body 31, that is, the side of the limiting groove 35 away from the groove opening does not communicate with the assembly cavity 34.

[0052] In one implementation method, please refer to the specific details. Figure 4 and Figure 5As shown, the inner support body 31 has a protrusion 39 protruding towards the inner side of the assembly cavity 34. The protrusion 39 extends along the groove depth direction and abuts against the magnetic component 32, forming a gap between the magnetic component 32 and the cavity wall of the assembly cavity 34. Preferably, each inner cavity wall of the assembly cavity 34 is provided with at least one protrusion 39. Of course, at least one protrusion 39 can also be provided on each of the two opposite inner cavity walls of the assembly cavity 34. In this way, after the magnetic component 32 is embedded in the assembly cavity 34, the protrusion 39 can form a stable abutment with the surface of the magnetic component 32.

[0053] The protrusion 39 in this embodiment allows for a larger tolerance range in the dimensions of the assembly cavity 34 during the design process, making it easier to design. For example, in this embodiment, the opening size of the assembly cavity 34 can be designed to be larger than the outer contour size of the magnetic component 32, which facilitates the placement of the magnetic component 32 inside. Furthermore, during the assembly process of the magnetic component 32 into the assembly cavity 34, the protrusion 39 can also achieve an interference fit with the magnetic component 32, thereby ensuring that the magnetic component 32 can be stably positioned in the assembly cavity 34.

[0054] In one implementation method, please refer to the specific details. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the inner tray body 31 has a limiting protrusion 36 extending along the length L of the charging slot 21. Preferably, the limiting protrusion 36 is provided on the opposite two outer side walls of the charging slot 21. Each limiting protrusion 36 can abut against the edge of the through-hole 22, aiming to provide a limiting constraint for the reciprocating movement of the inner tray body 31 in the depth direction of the charging slot 21. That is, by using the cooperation between the limiting protrusion 36 and the edge of the through-hole 22, the excessive movement of the inner tray body 31 can be effectively limited, preventing it from popping out of the through-hole 22. When the cover 10 is opened, as the inner tray body 31 moves the earphone body part out of the charging slot 21, the limiting protrusion 36 always remains in contact with the edge of the through-hole 22, controlling the movement of the inner tray body 31 within a safe range, and ensuring that the inner tray body 31 always abuts against the through-hole 22 during reciprocating movement. Meanwhile, the limiting protrusion 36 extends along the length direction L of the charging slot 21, increasing the contact range with the edge of the through-hole 22, making the limiting force distribution more uniform, further improving the reliability of the limiting effect, and effectively reducing the risk of the inner support body 31 dislodging from the through-hole 22 while ensuring the flexibility of its movement.

[0055] In one implementation method, please refer to the specific details. Figures 1 to 4As shown, the headphone charging case 100 also includes charging contacts 40, which are located on the inner tray assembly 30. When the lid 10 is closed, the charging contacts 40 are electrically connected to the circuit board 50. When the lid 10 is open, the charging contacts 40 are separated from the circuit board 50. Thus, when the lid 10 is closed, the inner tray body 31 moves downwards along the groove depth direction to the charging position under the pressure of the lid 10. At this time, the charging contacts 40 make precise contact with the corresponding electrodes on the circuit board 50, forming a complete and stable power transmission circuit, providing a stable charging current to the headphone body, ensuring efficient and safe power transmission. When the lid 10 is open, the inner tray body 31 resets under the action of the elastic element 33, causing the charging contacts 40 to separate from the circuit board 50, automatically cutting off the charging circuit, thereby reducing the risk of damage caused by accidental collisions.

[0056] In one implementation method, please refer to the specific details. Figures 1 to 4 As shown, the inner tray body 31 is provided with a charging hole 37 for integrating and fixing the charging contact 40. Further, the charging contact 40 includes a terminal body 41 and a fixing part 42, wherein the fixing part 42 protrudes from the periphery of the terminal body 41 and connects to the inner wall of the charging hole 37. This connection can be either a snap-fit ​​or a tight connection. Under conditions of frequent removal and placement of the earphone body and reciprocating movement of the inner tray assembly 30, the fixing part 42 can effectively resist external impacts and vibrations, preventing the terminal body 41 from loosening or shifting, and ensuring that the charging contact 40 always maintains a stable connection state.

[0057] according to Figure 2 , Figure 3 and Figure 4 As shown, the terminal body 41 is inserted into the charging hole 37, and one end of the terminal body 41 near the circuit board 50 extends out of the charging hole 37 to form a first end 411. This first end 411 protrudes outward to ensure a reliable electrical connection with the corresponding electrode on the circuit board 50 when the lid 10 is closed and the inner tray body 31 moves down, forming a stable power input channel. The other end of the terminal body 41 away from the circuit board 50 extends out of the charging hole 37 to form a second end 412. The second end 412 is used to connect with the charging interface of the earphone body to realize the output conduction of power. In this way, the connection and separation with the circuit board 50 and the earphone body can be automatically completed during the opening and closing of the lid 10. This not only improves the charging reliability and service life of the earphone charging case 100, but also enhances the stability of the earphone charging case 100, bringing users a safer and more convenient charging experience.
