Description

Technical Field

[0001] This invention belongs to the field of electronic product manufacturing technology, and specifically relates to a charging box. Background Technology

[0002] Existing headphone charging cases are quite noisy when the lid is closed, and the lid is not stable enough when closed, with the top cover easily being thrown open and the top and bottom covers easily wobbling, which greatly reduces the user experience. Summary of the Invention

[0003] The present invention aims to provide a charging case that can at least solve the problems of excessive noise and unstable closing of existing charging cases.

[0004] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0005] This invention provides a charging case, comprising: a case body; a cover, the connecting end of which is movably connected to the case body; a first elastic member disposed at the connecting end of the cover; a connector disposed within the cover, the first end of which is connected to the first elastic member; a movable member disposed within the cover, the second end of which is connected to the movable member, the movable member being movable relative to the cover between a first position and a second position; and a suction cup disposed on the cover, the suction cup corresponding to the movable member in position, and a movable cavity forming between the suction cup and the movable member, the movable member being movable along the movable cavity between the first position and the second position, the suction cup having an adsorption surface.

[0006] Specifically, when the cover is at a first angle relative to the box, the first elastic element is in a first state, and the first elastic element drives the movable element to be located at the first position through the connector, and the suction cup is separated from the box; when the cover is at a second angle relative to the box, the first elastic element is in a second state, and the first elastic element drives the movable element to be located at the second position through the connector, and the suction surface of the suction cup is adsorbed and connected to the box.

[0007] In this embodiment of the invention, by providing a suction cup on the lid, when the lid is closed relative to the box, the suction cup contacts the box and forms an adsorption, which can effectively buffer the noise of the lid and box contacting each other at the moment of closure. Simultaneously, by providing a first elastic element, a connecting element, and a movable element, the connecting element can drive the movable element to move between a first position and a second position during the switching process between a first and second state. When the lid is at a second angle relative to the box, the first elastic element deforms, driving the connecting element to move the movable element from the first position to the second position. This removes some of the air from the active cavity formed between the suction cup and the movable element, ensuring a more stable adsorption between the suction cup and the box, and improving the stability of the lid and box closing.

[0036] The charging box 100 provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0037] like Figures 1 to 4 As shown, the charging case 100 according to an embodiment of the present invention includes a case body 10, a cover 20, a first elastic member 30, a connector 40, a movable member 50, and a suction cup 60.

[0038] Specifically, the connecting end of the cover 20 is movably connected to the box 10. A first elastic member 30 is located at the connecting end of the cover 20. A connecting member 40 is located inside the cover 20, with its first end connected to the first elastic member 30. A movable member 50 is located inside the cover 20, with its second end connected to the connecting member 40. The movable member 50 is movable relative to the cover 20 between a first position and a second position. A suction cup 60 is located on the cover 20, corresponding to the movable member 50, and forming a movable cavity 71 between the suction cup 60 and the movable member 50. The movable member 50 is movable along the movable cavity 71 between the first and second positions. The suction cup 60 has an adsorption surface 62. When the cover 20 is at a first angle relative to the box 10, the first elastic member 30 is in a first state, and the first elastic member 30 drives the movable member 50 to the first position via the connecting member 40, separating the suction cup 60 from the box 10. When the cover 20 is at a second angle relative to the box 10, the first elastic member 30 is in a second state. The first elastic member 30 drives the movable member 50 to be in a second position through the connector 40, and the suction surface 62 of the suction cup 60 is adsorbed and connected to the box 10.

[0039] In other words, see Figures 1 to 5 According to an embodiment of the present invention, the charging case 100 mainly consists of a case body 10, a cover 20, a first elastic member 30, a connector 40, a movable member 50, and a suction cup 60. Wherein, as... Figure 1 and Figure 2 As shown, the connecting end of the cover 20 is movably connected to the box 10, and the cover 20 can be opened or closed relative to the box 10. Figure 2 and Figure 3 As shown, the first elastic element 30 is disposed on the connecting end of the cover 20. During the movement of the cover 20, the first elastic element 30 can undergo elastic deformation and release elastic potential energy. The connecting element 40 is disposed inside the cover 20, and the first end of the connecting element 40 is connected to the first elastic element 30. When the first elastic element 30 undergoes elastic deformation, it can drive the connecting element 40 to move. The movable element 50 is disposed inside the cover 20, and the second end of the connecting element 40 is connected to the movable element 50. The movable element 50 can move between a first position and a second position relative to the cover 20. The suction cup 60 is disposed on the cover 20, and the position of the suction cup 60 corresponds to that of the movable element 50, and a movable cavity 71 is formed between the suction cup 60 and the movable element 50. The movable element 50 can move between the first position and the second position along the movable cavity 71. The suction cup 60 has an adsorption surface 62 (see Figure 8 By moving the movable part 50 in the first and second positions, some of the air in the movable cavity 71 can be removed, ensuring that the suction cup 60 adheres more stably to the box body 10 and preventing the cover 20 from shaking.

[0040] When the cover 20 is at a first angle relative to the box 10, such as Figure 2 As shown, the first elastic element 30 is in the first state. At this time, the first elastic element 30 can drive the movable element 50 to the first position via the connecting element 40, and the suction cup 60 separates from the housing 10, making it easy for the user to remove the earphone 90 from the housing 10. When the cover 20 has a second angle relative to the housing 10, see... Figure 3 The first elastic element 30 is in the second state. At this time, the first elastic element 30 drives the movable element 50 to the second position through the connecting element 40. During the process of the movable element 50 moving from the first position to the second position, some air in the movable cavity 71 is removed, ensuring that the adsorption surface 62 of the suction cup 60 is more firmly adsorbed to the box body 10. The contact area between the box body 10 and the adsorption surface 62 of the suction cup 60 is a smooth plane, which facilitates the adsorption of the suction cup 60 onto the box body 10.

[0041] In this invention, the first angle between the cover 20 and the box 10 can be the state when the cover 20 is open relative to the box 10 (see [reference]). Figure 1 The second angle that the lid 20 has relative to the box 10 can be the state when the lid 20 is closed relative to the box 10 (see...). Figure 3 ).

[0042] It should be noted that the charging case 100 also contains a self-generating torsion spring 85 or other structure (such as...) that can instantly open or close the cover 20. Figure 2 , Figure 3 and Figure 11 As shown, the cover 20 is designed to allow users to open or close it instantly. When the cover 20 of the charging case 100 is closed, the suction cup 60 effectively buffers the noise from the instant the cover 20 and the case 10 come into contact. Simultaneously, because the closing action is instantaneous, the release of the elasticity of the first elastic element 30 is relatively delayed, allowing the movable element 50 to move from the first position to the second position immediately after the cover 20 is closed, carrying away some air from the movable cavity 71 and achieving a stable connection between the cover 20 and the case 10, preventing the cover 20 from shaking relative to the case 10.

[0043] Therefore, according to the embodiment of the present invention, the charging case 100, by providing a suction cup 60 on the cover 20, when the cover 20 is closed relative to the case 10, the suction cup 60 contacts the case 10 and forms an adsorption, which can effectively buffer the noise of the instantaneous contact between the cover 20 and the case 10 upon closing. Simultaneously, by providing a first elastic element 30, a connecting element 40, and a movable element 50, the connecting element 40 can drive the movable element 50 to move between a first position and a second position during the switching process between the first elastic element 30 and the second state. When the cover 20 is closed relative to the case 10, the first elastic element 30 deforms, driving the connecting element 40 to move the movable element 50 from the first position to the second position, thereby removing some of the air from the movable cavity 71 formed between the suction cup 60 and the movable element 50, ensuring a more stable adsorption between the suction cup 60 and the case 10, and improving the stability of the closing between the cover 20 and the case 10.

[0044] According to one embodiment of the present invention, the first elastic member 30 is connected to the cover 20 via a pivot 86. When the cover 20 is at a first angle relative to the box 10, the first elastic member 30 is in an extended state. The first elastic member 30 drives the connecting member 40 to move, thereby driving the movable member 50 to move to the first position, and the suction cup 60 separates from the box 10. When the cover 20 is at a second angle relative to the box 10, the first elastic member 30 is in a contracted state. The first elastic member 30 drives the connecting member 40 to move, thereby driving the movable member 50 to move to the second position, and the suction surface 62 of the suction cup 60 is adsorbed and connected to the box 10.

[0045] In other words, such as Figure 2 and Figure 3As shown, the first elastic element 30 can be connected to the cover 20 via a pivot 86. The pivot 86 can be fixedly connected to the cover 20, and the pivot 86 and the cover 20 rotate clockwise or counterclockwise together. The first elastic element 30 is fixed to the pivot 86. During the opening or closing of the cover 20, the pivot 86 causes the first elastic element 30 to undergo elastic deformation. When the cover 20 is open relative to the housing 10 (when the cover 20 is at a first angle relative to the housing 10), the first state of the first elastic element 30 is the extended state. At this time, the first elastic element 30 can drive the movable element 50 to the first position via the connector 40, and the suction cup 60 separates from the housing 10, making it convenient for the user to remove the earphone 90 from the housing 10. When the cover 20 is closed relative to the box 10 (when the cover 20 is at a second angle relative to the box 10), the second state of the first elastic member 30 is the contracted state. At this time, the first elastic member 30 can store a certain elastic potential energy and release the elastic potential energy at this instant, thereby driving the connecting member 40 to move the movable member 50 from the first position to the second position, drawing away the air inside the suction cup 60, and ensuring that the suction cup 60 can stably hold the box 10.

[0046] According to one embodiment of the present invention, a connecting post 70 is provided in the end of the cover 20 away from the connecting end, and a hollow movable cavity 71 is formed in the connecting post 70. One end of the movable member 50 extends into the movable cavity 71, and a suction cup 60 is provided at the end of the connecting post 70 opposite to the movable member 50.

[0047] In other words, see Figure 2 and Figure 3 A connecting post 70 is provided at the end of the cover 20 away from the connecting section. A hollow movable cavity 71 is provided within the connecting post 70. One end of the movable member 50 can extend into the movable cavity 71. A suction cup 60 is located at the end of the connecting post 70 opposite to the movable member 50, and the suction cup 60 is in communication with the movable cavity 71. When the cover 20 is closed, the first elastic member 30 drives the movable member 50 to move relative to the connecting post 70 via the connecting member 40, moving it from a first position to a second position to remove some air from the connecting post 70, making the suction cup 60 more stably adhered to the box 10.

[0048] In some specific embodiments of the present invention, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the first elastic element 30 includes multiple annular spring sheets 31, which can be helically connected to form a columnar structure. The multiple annular spring sheets 31 can switch between an extended and a contracted state, storing or releasing elastic potential energy to drive the connecting member 40 and thus the movable member 50 to move within the connecting column 70. Optionally, the first elastic element 30 can be a helical steel sheet, and the movable member 50 can be a piston (see...). Figure 10By storing or releasing elastic potential energy through the spiral steel sheet, the connecting piece 40 drives the piston to move within the connecting column 70, ensuring that the suction cup 60 can be more firmly attached to the box 10.

[0049] According to one embodiment of the present invention, a tongue 61 is provided on the suction cup 60. The tongue 61 is located on one side of the suction surface 62 of the suction cup 60. When the cover 20 is at a second angle relative to the box 10, a portion of the tongue 61 extends out of the charging box 100. When the cover 20 is at a second angle relative to the box 10, the tongue 61 can be used to switch the cover 20 relative to the box 10 to a first angle.

[0050] In other words, such as Figure 4 and Figure 8 As shown, a tongue 61 can be provided on the suction cup 60. The tongue 61 is located on one side of the suction surface 62 of the suction cup 60, and the tongue 61 and the suction surface 62 are on the same side of the suction cup 60. When the cover 20 is at a second angle relative to the box 10, a part of the tongue 61 extends out of the charging box 100. The user can use the tongue 61 to switch the cover 20 relative to the box 10 to a first angle, thereby opening the charging box 100. Specifically, when the user needs to open the charging box 100, the cover 20 is in a closed state relative to the box 10 (the cover 20 is at a second angle relative to the box 10). By providing the tongue 61 on the suction cup 60, when the user opens the cover 20, they can move the tongue 61 to allow outside air to enter the suction cup 60, facilitating the separation of the suction cup 60 from the box 10 and switching the charging box 100 from a closed state to an open state, making it more convenient for the user to open the cover.

[0051] According to one embodiment of the present invention, see Figure 2 and Figure 3 The connector 40 is a wire, one end of which is connected to the first elastic member 30, and the other end of which is connected to the movable member 50. When the cover 20 is at a first angle relative to the box 10, the first elastic member 30 is in an extended state. The first elastic member 30 drives the movable member 50 to a first position through the wire, and the suction cup 60 is separated from the box 10. When the cover 20 is at a second angle relative to the box 10, the first elastic member 30 is in a contracted state. The wire is wound around the outer wall of the first elastic member 30. The first elastic member 30 drives the movable member 50 to a second position through the wire, and the suction surface 62 of the suction cup 60 is adsorbed and connected to the box 10.

[0052] In other words, such as Figure 2 and Figure 3As shown, the connector 40 can be a wire, such as a steel wire. One end of the wire is connected to the first elastic member 30, and the other end is connected to the movable member 50. When the cover 20 is opened relative to the box 10 (the cover 20 is at a first angle relative to the box 10), the first elastic member 30 is in an extended state. The first elastic member 30 can drive the movable member 50 to a first position via the wire, and the suction cup 60 separates from the box 10. When the cover 20 is closed relative to the box 10 (the cover 20 has a second angle relative to the box 10), the first elastic element 30 is in a contracted state. The first elastic element 30 stores elastic potential energy and releases the elastic potential energy after the cover 20 is closed. The first elastic element 30 expands, and at this time the thread wraps around the outer wall surface of the first elastic element 30. The first elastic element 30 drives the movable element 50 to the second position through the thread, thereby taking away the air in the movable cavity 71, ensuring that the adsorption surface 62 of the suction cup 60 is more firmly adsorbed to the box 10, and preventing the cover 20 from shaking relative to the box 10.

[0053] In some specific embodiments of the present invention, the charging box 100 further includes a conductive member 81, which is disposed inside the cover 20 and located between the movable member 50 and the first elastic member 30. The connecting member 40 is movable along the conductive member 81.

[0054] In other words, see Figure 2 and Figure 3 The charging case 100 may also include a conductive member 81 disposed within the cover 20. The conductive member 81 is generally located between the movable member 50 and the first elastic member 30. During the elastic deformation of the first elastic member 30, the connecting member 40 is movable along the conductive member 81. The conductive member 81 may be a pulley (see...). Figure 2 and Figure 10 The pulley serves as a conductor, facilitating the movement of the steel wire rope (connector 40) within the cover 20, between the first and second positions.

[0055] According to one embodiment of the present invention, a cap 21 is provided inside the cover 20. The cap 21 is located between the conductive member 81 and the first elastic member 30. The edge of the cap 21 is provided with a protruding edge 22. The connecting member 40 is sequentially wound around the protruding edge 22 and the conductive member 81.

[0056] In other words, such as Figure 2 and Figure 3 As shown, a cap 21 can be provided inside the cover 20. The cap 21 is generally positioned between the conductor 81 and the first elastic member 30. The edge of the cap 21 is provided with a protruding edge 22, and the connecting member 40 can be sequentially wound around the protruding edge 22 and the conductor 81. By providing a cap 21 with a protruding edge 22, it is easier for the wire rope to move smoothly inside the cover 20.

[0057] According to one embodiment of the present invention, the cover 20 is provided with a mounting plate 82, the mounting plate 82 and the connecting post 70 are spaced apart to form a cavity 83, the mounting plate 82 is provided with a through hole, one end of the movable member 50 extends into the connecting post 70, the other end of the movable member 50 is located in the cavity 83, and one end of the connecting member 40 passes through the through hole and is connected to the movable member 50.

[0058] In other words, see Figure 2 , Figure 3 and Figure 5 The cover 20 is provided with an installation plate 82. The installation plate 82 and the connecting post 70 can be spaced apart to form a cavity 83. The installation plate 82 is provided with a through hole. One end of the movable member 50 extends into the connecting post 70, and the other end of the movable member 50 is located in the cavity 83. One end of the connecting member 40 passes through the through hole and connects with the movable member 50, so that the movable member 50 can move between the first position and the second position.

[0059] According to one embodiment of the present invention, the charging box 100 further includes a second elastic member 84, which is disposed in the cavity 83, one end of the second elastic member 84 is connected to the movable member 50, and the other end of the second elastic member 84 is connected to the mounting plate 82.

[0060] In other words, such as Figure 2 and Figure 3 As shown, the charging case 100 also includes a second elastic element 84, which can be a spring. The second elastic element 84 is disposed within the cavity 83, with one end connected to the movable member 50 and the other end connected to the mounting plate 82. By providing the second elastic element 84, the movable member 50 can be elastically reset between the first and second positions, improving the efficiency of the movable member 50's movement.

[0061] In summary, the charging case 100 according to the embodiments of the present invention, by providing a suction cup 60 on the cover 20, when the cover 20 is closed relative to the case 10, the suction cup 60 contacts the case 10 and forms an adsorption, which can effectively buffer the noise of the instantaneous contact between the cover 20 and the case 10 upon closing. Simultaneously, by providing a first elastic element 30, a connecting element 40, and a movable element 50, the connecting element 40 can drive the movable element 50 to move between a first position and a second position during the switching process between the first elastic element 30 and the second state. When the cover 20 is closed relative to the case 10, the first elastic element 30 deforms, driving the connecting element 40 to move the movable element 50 from the first position to the second position, thereby removing some of the air from the movable cavity 71 formed between the suction cup 60 and the movable element 50, ensuring a more stable adsorption between the suction cup 60 and the case 10, and improving the stability of the closing between the cover 20 and the case 10.
