Description

Technical Field

[0001] This application belongs to the field of headphone charging structure technology, specifically relating to a charging case and headphone assembly. Background Technology

[0002] Earphone charging cases typically have earphone storage slots that are compatible with wireless earphones for storing them.

[0003] In related technologies, wireless earbuds are typically removed from the charging case in a straight-up-down motion, which neither makes full use of space nor improves the user experience. Furthermore, when stored in the earbud slot, charging is usually done via a charging port located within the slot. However, when removing the earbuds from the slot, they inevitably shift, which can cause the charging port to scratch the earbuds, thus affecting their normal use.

[0004] Therefore, how to ensure the efficient use of the charging case space and the convenience and integrity of removing the wireless earbuds from the charging case while maintaining the storage effect of the wireless earbuds has become an urgent problem to be solved in the industry. Summary of the Invention

[0005] This application aims to provide a charging case and earphone assembly that can solve the problems of insufficient space utilization in the charging case and easy damage to the earphones when they are taken out of the charging case.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application propose a charging case, comprising:

[0008] A housing, wherein a movable plate and a fixed plate are provided, the movable plate being movable relative to the fixed plate, the movable plate and the fixed plate forming a slot, the depth direction of the slot having a first angle with the depth direction of the housing, the slot being used to accommodate an earphone;

[0009] The first charging terminal is located on the inner side of the movable plate;

[0010] When the earphone and the slot are in a first relative position, the movable plate separates from the fixed plate, and the first charging terminal separates from the charging terminal of the earphone;

[0011] When the earphone and the slot are in a second relative position, the movable plate and the fixed plate surround each other, the earphone is placed in the slot, and the first charging terminal is in contact with the charging terminal of the earphone.

[0012] Secondly, embodiments of this application provide an earphone assembly, including earphones and the charging case described in the first aspect.

[0013] This application provides a charging case comprising a housing and a first charging terminal. When the earphones and the slot are in a first relative position, the movable plate separates from the fixed plate, and the first charging terminal separates from the charging end of the earphones. When the earphones and the slot are in a second relative position, the movable plate and the fixed plate enclose the earphones, the earphones are placed in the slot, and the first charging terminal contacts the charging end of the earphones. The depth direction of the slot forms a first angle with the depth direction of the housing, meaning the slot is obliquely positioned within the housing. This fully utilizes the space of the charging case. When the first charging terminal is separated from the charging end of the earphones, it avoids obstructing the earphones, ensuring both effective earphone storage and convenient and intact removal of the earphones from the charging case.

[0038] The following is combined Figure 1 - Figure 15 This application describes a charging case and earphone assembly according to embodiments thereof.

[0039] like Figures 1 to 3 As shown, according to some embodiments of this application, a charging case is provided. The charging case is used to charge earphones; for example, the charging case can charge wireless earphones while simultaneously storing them. The charging case includes:

[0040] The housing 1 and the first charging terminal 2 are provided. The housing 1 is provided with a movable plate 12 and a fixed plate. The movable plate 12 is movable relative to the fixed plate. The movable plate 12 and the fixed plate form a slot 11. The depth direction of the slot 11 has a first angle with the depth direction of the housing 1. The slot 11 is used to accommodate earphones. For example, the slot 11 can be plugged into the earphones to realize the simultaneous storage of earphones and charging of earphones through the charging case.

[0041] Specifically, the depth direction of the housing 1 can be the height direction when the charging case is placed, for example, the depth direction of the charging case can be as follows: Figure 4 In the Z direction, when the charging box is placed on a support surface such as a desktop, the opening of the slot 11 can be located at the top of the housing 1, and the depth direction of the slot can be the direction in which the opening of the slot extends towards the bottom of the slot.

[0042] When the depth direction of the slot 11 forms a first angle with the depth direction of the housing 1, that is, the slot 11 is tilted and disposed on the housing 1, and the first angle can be adjusted within the range of 0-90°. When the earphone is accommodated in the slot 11, the earphone can be tilted and inserted into the opening of the slot 11 from the top of the housing 1, thereby reducing the size occupied by the earphone in the height direction of the charging case. This achieves miniaturization of the charging case by reducing its height.

[0043] See Figure 2 and Figure 3 The first charging terminal 2 is located on the inner side of the movable plate 12. Since the fixed plate is fixed in the housing 1, and the movable plate 12 is movable relative to the fixed plate, the movable plate 12 can move inside the housing 1, thereby driving the first charging terminal 2 to move inside the housing 1.

[0044] When the earphone and the slot 11 are in a first relative position, the movable plate 12 separates from the fixed plate, and the first charging terminal 2 separates from the charging terminal of the earphone.

[0045] Specifically, the first relative position between the earphone and the slot 11 can be the relative position when the earphone is removed from the slot 11. See also Figure 6 When the earphone is removed from the slot 11, the earphone needs to be removed from the slot 11 while moving or even shaking. In order to avoid the earphone being scratched by the first charging terminal 2 when it is moving, the movable plate 12 can be made to move the first charging terminal 2 within the housing 1. When the movable plate 12 is separated from the fixed plate, the first charging terminal 2 is separated from the charging terminal of the earphone.

[0046] For example, the movement of the first charging terminal 2 within the housing 1 is synchronized with the movement of the earphone when it is removed. Specifically, the direction and amplitude of the movement of the first charging terminal 2 within the housing 1 can be the same as the direction and amplitude of the movement of the earphone when it is removed. This allows the first charging terminal 2 to separate from the charging end of the earphone when it is removed from the slot 11, thus avoiding the earphone and ensuring the integrity of the earphone when it is removed from the slot 11.

[0047] When the earphone and the slot 11 are in a second relative position, the movable plate 12 and the fixed plate surround each other, the earphone is placed in the slot 11, and the first charging terminal 2 is in contact with the charging terminal of the earphone.

[0048] Specifically, see Figure 4 and Figure 5 When the earphones and the slot 11 are in a second relative position, the movable plate 12 can be formed with the fixed plate to create a complete slot 11, so that the earphones can be stored in the slot 11. When the earphones are inserted into the slot 11, the first charging terminal 2 is used to contact and abut against the charging terminal of the earphones. At this time, the charging case can charge the earphones while storing them.

[0049] Specifically, the slot 11 may include a first plug-in section and a second plug-in section. The earphone includes an earphone head and an earphone stem. When the earphone is stored in the slot 11, the earphone stem can be inserted into the first plug-in section, while the earphone head is stored in the second plug-in section. The plug-in space formed by the first plug-in section can match the earphone stem, and the receiving space formed by the second plug-in section can match the earphone head, so as to ensure the stability of the earphone stored in the slot 11.

[0050] When the earphone and the slot 11 are in a first relative position, the movement of the first charging terminal 2 within the housing 1 can be achieved by the circuit board provided in the charging case controlling the movement of the movable plate 12. For example, the circuit board can control the movement of the driving components such as the electrodes connected to the first charging terminal 2 in the movable plate 12, thereby enabling the first charging terminal 2 to move within the housing 1. Alternatively, the movement of the first charging terminal 2 within the housing 1 can also be achieved by using the movement of the earphone moving out of the slot 11 to drive the first charging terminal 2 to move within the housing 1. For example, when the earphone moves out of the slot 11, it can squeeze the end of the first charging terminal 2, thereby enabling the first charging terminal 2 to move within the housing 1.

[0051] In addition, the charging case may also include a cover 5, which is movably connected to the housing 1. The housing 1 has two slots 11, which can be used to store two earphones, that is, earphones corresponding to the left and right ears respectively.

[0052] The charging case provided in this embodiment includes a housing 1 and a first charging terminal 2. When the earphone and the slot 11 are in a first relative position, the movable plate 12 separates from the fixed plate, and the first charging terminal 2 separates from the charging end of the earphone. When the first charging terminal 2 is separated from the charging end of the earphone, it can avoid obstructing the earphone, thus ensuring the convenience and integrity of taking the earphone out of the charging case while maintaining the earphone's storage effect.

[0053] Optionally, see Figures 6 to 11 The movable plate 12 has a first end 121 and a second end 122 that are far apart from each other. The first end 121 is located at the opening of the slot 11, and the second end 122 is located on the side of the slot 11 near the bottom of the slot 11. The first charging terminal 2 is fixed to the second end 122.

[0054] When the earphones are inserted into the charging case so that the earphones and the slot 11 are in a first relative position, the earphones drive the second end 122 to move the movable plate 12, the movable plate separates from the fixed plate, and the first charging terminal separates from the charging terminal of the earphones;

[0055] When the earphone is removed from the charging case so that the earphone and the slot 11 are in a first relative position, the earphone drives the first end 121 to move, thereby moving the movable plate 12. The movable plate separates from the fixed plate, and the first charging terminal separates from the charging terminal of the earphone.

[0056] Specifically, the earphone being in the first relative position with respect to the slot 11 can be either when the earphone enters the charging case or when the earphone is removed from the charging case. When the earphone enters or leaves the charging case, it will move relative to the first charging terminal 2. To prevent the earphone from being scratched by the first charging terminal 2 during movement, the earphone can drive the first end 121 or the second end 122 to move, thereby causing the movable plate 12 to move the first charging terminal 2 within the housing 1. When the movable plate 12 separates from the fixed plate, the first charging terminal 2 is separated from the charging end of the earphone, ensuring the integrity of the earphone when it enters or leaves the charging case.

[0057] Optionally, when the earphone enters the charging case so that the earphone and the slot 11 are in a first relative position, the movable plate 12 separates from the fixed plate to form a first separation gap; when the earphone is removed from the charging case so that the earphone and the slot 11 are in a first relative position, the movable plate 12 separates from the fixed plate to form a second separation gap.

[0058] The first separation distance is smaller than the second separation distance.

[0059] Specifically, when the earphones enter the charging case, they come into contact with the first charging terminal 2. Since the movable plate 12 can move within the housing 1, the first charging terminal 2 can also move within the housing 1. When the earphones come into contact with the first charging terminal 2, they can push the first charging terminal 2 to move, causing the movable plate 12 to separate from the fixed plate, forming a first separation distance; the first separation distance can be the distance between the bottom end of the movable plate 12 and the bottom end of the fixed plate.

[0060] When the earphone is removed from the charging case, it can push the first end 121 of the movable plate 12 to move, causing the movable plate 12 to deflect. When the movable plate 12 deflects, it can use the second end 122 to move the first charging terminal 2 away from the earphone, thus forming a second separation gap after the movable plate 12 separates from the fixed plate. Furthermore, with the second separation gap formed after the movable plate 12 separates from the fixed plate, the first charging terminal 2 separates from the earphone, meaning the second separation gap is greater than the first separation gap, further preventing damage to the earphone from the first charging terminal 2.

[0061] Optionally, see Figure 6, Figure 10 and Figure 11 The housing 1 is provided with a rotating shaft 13, the movable plate 12 is rotatably connected to the rotating shaft 13, and the first end 121 and the second end 122 are respectively located on both sides of the rotating shaft 13.

[0062] Specifically, when the movable plate 12 is rotatably connected to the rotating shaft 13, the first end 121 and the second end 122 are located on both sides of the rotating shaft 13, that is, the first end 121 and the second end 122 can form a structure similar to a seesaw.

[0063] See Figure 11 When the earphone is removed from the slot 11, it can be moved closer to the first end 121, allowing it to rotate a certain angle and slide out. The earphone will then push the first end 121, causing the movable plate 12 to rotate clockwise around the pivot 13. Since the first charging terminal 2 is fixed to the second end 122, its clockwise rotation around the pivot 13 allows the first charging terminal 2 to rotate with the earphone. This prevents excessive force on the earphone stem during removal, thus cushioning the force exerted when removing the earphone.

[0064] In one embodiment, the movable plate 12 can be formed into a U-shaped structure similar to a U-shaped movable plate, see [reference needed]. Figure 10 and Figure 11 The earphone includes an earphone head and an earphone stem. A first end 121 is located at the upper right part of the slot 11, and a second end 122 is located at the lower left part of the slot 11. When the earphone is inserted into the slot 11, the earphone head abuts against the first end 121, and the first charging terminal 2 abuts against the charging terminal of the earphone to enable charging of the earphone through the charging case. When the earphone is removed from the slot 11, the earphone can be deflected clockwise by pushing the first end 121 clockwise with the earphone head. At this time, the earphone stem rotates to the upper left when it is deflected clockwise, and the second end 122 can also rotate to the upper left when it follows the clockwise deflection of the first end 121. The second end 122 can drive the first charging terminal 2 to rotate to the upper left in the slot 11. That is, the movement of the second end 122 and the first charging terminal 2 is synchronized with the movement of the earphone stem on the earphone, so that the first charging terminal 2 avoids the deflection of the earphone when it is removed, avoids the first charging terminal 2 from scratching the earphone, and ensures the integrity of the earphone when it is removed.

[0065] Optionally, see Figure 7An elastic element 14 is provided on the rotating shaft 13. One end of the elastic element 14 abuts against the movable plate 12, and the other end of the elastic element 14 abuts against the housing 1. The elastic element 14 is used to restore the movable plate 12 and the fixed plate from the separated state to the enclosed state.

[0066] Specifically, the elastic element 14 can be a return spring or a torsion spring. When the earphone is removed from the slot 11, it can be moved towards the first end 121, and the earphone can be rotated out by rotating the movable plate 12 clockwise around the pivot 13. Since one end of the elastic element 14 abuts against the movable plate 12 and the other end of the elastic element 14 abuts against the housing 1, when the movable plate 12 rotates clockwise around the pivot 13 and separates from the fixed plate, the movable plate 12 can force the elastic element 14 to undergo elastic deformation.

[0067] After the earphone is completely removed from the slot 11, the elastic member 14 can use its force to return to the initial state to reset the movable plate 12, that is, to restore the movable plate 12 and the fixed plate to the enclosed state, so as to ensure the integrity of the slot 11.

[0068] Similarly, after the earphone enters the slot 11 and avoids the earphone at the first charging terminal 2, the elastic member 14 can restore the movable plate 12 and the fixed plate to the enclosed state to ensure that the charging case charges the earphone through the first charging terminal 2.

[0069] In addition, the elastic element 14 can maintain an initial preload when in the initial state, so that the first end 121 can be tightly pressed against the earphone by the preload of the elastic element 14 on the movable plate 12, thus ensuring the stability of the earphone in the slot 11.

[0070] Optionally, a limiting part is provided on the first end 121, which is used to fix the earphone when the earphone is inserted into the slot 11.

[0071] In one embodiment, the limiting part can be an arc-shaped groove provided at the first end 121. The head of the earphone can be embedded in the arc-shaped groove. Under the pre-tightening action of the elastic member 14 on the movable plate 12, the arc-shaped groove can wrap around and clamp the head of the earphone to prevent the earphone from shaking in the slot 11.

[0072] Optionally, when the earphones are inserted into the charging case such that the earphones are in a first relative position with the slot 11, the earphones contact the second end 122 to drive the movable plate 12 to rotate, the movable plate separates from the fixed plate, and the first charging terminal separates from the charging terminal of the earphones;

[0073] When the earphone is removed from the charging case so that the earphone and the slot 11 are in a first relative position, the earphone abuts against the first end 121 when it rotates, thereby causing the movable plate 12 to rotate. The movable plate separates from the fixed plate, and the first charging terminal separates from the charging terminal of the earphone.

[0074] Specifically, when the earphone is removed from the slot 11, the earphone can abut against the first end 121 and push the first end 121 to move when it rotates. For example, the user can make the earphone rotate a set angle in the slot 11 by manually turning the earphone.

[0075] Since the first end 121 is located at the opening of the slot 11 and is used to abut against the earphone, the earphone can push the first end 121 to move when it rotates, thus enabling the entire movable plate 12 to rotate. When the second end 122 moves, it can drive the first charging terminal 2 to move within the housing 1. The movement of the first charging terminal 2 within the housing 1 can be synchronized with the rotation of the earphone when it is removed, allowing the first charging terminal 2 to avoid the earphone, thus enabling the earphone to be rotated out. This improves the experience of removing the earphone from the charging case while ensuring the integrity of the earphone removal process.

[0076] Optionally, see Figure 12 The first charging terminal 2 has an inclined protrusion 21 facing into the slot 11. When the earphone is inserted into the charging case so that the earphone and the slot 11 are in a first relative position, the inclined protrusion 21 is used to abut against the charging terminal of the earphone.

[0077] Specifically, the first charging terminal 2 can be an elastic terminal formed by a metal spring. When the inclined protrusion 21 is positioned towards the slot 11, the inclined protrusion 21 can include an inclined surface facing the opening of the slot 11. When the earphone is inserted into the charging case and thus inserted into the slot 11, the inclined surface of the inclined protrusion 21 facilitates the earphone's insertion into the slot 11, avoiding obstruction of the earphone by the inclined protrusion 21. Moreover, when the earphone is fully inserted into the slot 11, the inclined protrusion 21 can abut against the charging end of the earphone to achieve the purpose of charging the earphone through the charging case.

[0078] Optionally, the charging box further includes a circuit board disposed inside the housing 1, and the first charging terminal 2 is electrically connected to the circuit board via a flexible connector 3.

[0079] Specifically, the flexible connector 3 can be a flexible circuit or an FPC (flexible printed circuit board). For example, when the flexible connector 3 is an FPC, the first charging terminal 2 can be fixed to the movable plate 12 by a reinforcing plate. After the FPC passes through the reinforcing plate, it can achieve an electrical connection with the first charging terminal 2. This way, when the second end 122 drives the first charging terminal 2 to move within the housing 1, the FPC can maintain a stable connection with the first charging terminal 2 while deforming.

[0080] When the first charging terminal 2 is electrically connected to the circuit board via the flexible connector 3, a battery connected to the circuit board can also be provided in the housing 1, so that the circuit board can charge the earphones through the first charging terminal 2.

[0081] Optionally, see Figure 3 The charging box also includes a second charging terminal 4, which is located on the inner side of the fixing plate near the bottom of the slot 11.

[0082] When the earphone and the slot 11 are in a second relative position, the first charging terminal 2 and the second charging terminal 4 are used to abut against the charging terminals of the earphone with different polarities.

[0083] Specifically, the second charging terminal 4 can be electrically connected to the circuit board, and when the earphone is inserted into the slot 11, the first charging terminal 2 can abut against the positive charging terminal on the earphone, and the second charging terminal 4 can abut against the negative charging terminal on the earphone. Through the cooperation of the first charging terminal 2 and the second charging terminal 4, the charging case can charge the earphone, ensuring the earphone's battery life.

[0084] See Figures 1 to 4 This application embodiment also provides an earphone assembly, which includes an earphone 200 and the charging case.

[0085] Specifically, the charging case of the earphone assembly includes a housing 1 and a first charging terminal 2. When the earphone and the slot 11 are in a first relative position, the movable plate 12 separates from the fixed plate, and the first charging terminal 2 separates from the charging end of the earphone. When the first charging terminal 2 is separated from the charging end of the earphone, it can avoid obstructing the earphone 200, thereby ensuring the convenience and integrity of removing the earphone 200 from the charging case while maintaining the storage effect of the earphone 200.
