[0030] To further illustrate each embodiment, the present utility model provides accompanying drawings. These drawings are part of the disclosure of the present utility model, and are mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0031] Now, the present utility model will be further described in conjunction with the accompanying drawings and the detailed implementation manners.

[0032] As Figure 1-11 shown, this embodiment provides a charging case 1 with a damping structure, which includes an upper cover 10 and a lower cover 20. A receiving cavity 21 is formed in the lower cover 20, and the receiving cavity 21 is used to accommodate rechargeable devices such as earphones or hearing aids. The receiving cavity 21 opens upward, and the upper cover 10 is pivotally connected to the lower cover 20, so that the upper cover 10 can be in a closed state or an open state relative to the lower cover 20. A charging circuit is provided in the charging case 1 for charging rechargeable devices such as earphones. Regarding the charging circuit, it is a well-known technology at present and will not be elaborated here.

[0033] A rotating structure 30 is provided between the upper cover 10 and the lower cover 20, and the rotating structure 30 enables the upper cover 10 to flip relative to the lower cover 20. As Figure 5 , 7 shown, under the action of an external force, the upper cover 10 flips open relative to the lower cover 20 through the rotating structure 30 to expose the receiving cavity 21 in the lower cover 20. The upper cover 10 includes an upper outer cover 11 and an upper inner lining 12, and the lower cover 20 includes a lower outer cover 21 and a lower inner lining 22.

[0034] One of the upper cover 10 and the lower cover 20 of the charging case 1 may be provided with a damping member 50, and the other of the upper cover 10 and the lower cover 20 may be provided with a convex portion 60. That is, the upper cover 10 of the charging case 1 may be provided with a damping member 6, and the lower cover 20 may be provided with a convex portion 60, or the upper cover 10 of the charging case 1 may be provided with a convex portion 60, and the lower cover 20 may be provided with a damping member 6.

[0035] As Figures 4-6 shown, in this embodiment, the damping member 50 of the charging case 1 is provided on the lower cover 20, and the convex portion 60 is provided on the upper cover 10.

[0036] As Figure 4 shown, in this embodiment, the convex portion 60 abuts against the damping member 50. When the damping member 50 rotates relative to the lower cover 20, the convex portion 60 rotates along the rotation trajectory, and while rotating, the convex portion 60 slides on the damping member 50 and presses tightly against the damping member 50.

[0037] The damping member 50 is disposed in a cavity formed between the lower outer cover 21 and the lower inner lining 22. The damping member 50 includes a upper abutting section 51, an arc section 52, an intermediate section 53, a transition section 54, and a lower mounting section 55 that are connected in sequence. The arc section 52 is located between the abutting section 51 and the intermediate section 53, and the arc section 52 protrudes in an arc shape toward a direction away from the lower inner lining 22. The arc section 52 has a convex surface 521 and a concave surface 522 opposite to the convex surface 521. The convex surface 521 of the arc section 52 abuts against and contacts the damping member 50. The damping member 50 is made of an elastic material. For example, the damping member 50 is a metal shrapnel, specifically, it can be made of stainless steel or carbon spring steel, etc.

[0038] The arc section 52 of the damping member 50 can be formed by pressing an arc structure from above a metal sheet through a stamping die, such as a 0.3 mm metal sheet. The arc structure can be, for example, a semi-circle, and the radius of the arc structure can be 6 mm.

[0039] The rotating structure 30 includes a rotating block 31 extending downward from the lower end of the upper cover 10; a first rotating hole 34 horizontally passing through the rotating block 31; a notch 33 opened at the upper end of the lower cover 20, into which the rotating block 31 can be inserted; second rotating holes 35 provided on both sides of the notch 33 of the lower cover 20; and a rotating shaft 32 passing through the first rotating hole 34 and the second rotating hole 35. The setting of the rotating structure 30 enables the upper cover 10 to rotate relative to the lower cover 20.

[0040] A first notch 331 is opened at the upper end of the lower outer cover 21, and a second notch 332 is opened at a position of the lower inner lining 22 adjacent to the first notch 331. The first notch 331 and the second notch 332 together form the notch 33 on the lower cover 20.

[0041] The damping member 50 is disposed on one side of the rotating structure 30. A rotating block 31 extends downward from the lower end of the upper cover 10, and the convex portion 60 protrudes downward from the bottom of the rotating block 31. When the upper cover 10 rotates and opens relative to the lower cover 20, the convex portion 60 rotates around the pivot center axis of the rotating shaft 32 following the rotating block 31, and the convex portion 60 can rotate to abut against the convex surface 521 of the arc section 52.

[0042] It is defined that the upper cover 10 is located above the lower cover 20, the lower cover 20 is located below the upper cover 10, the damping member 50 is arranged in the cavity formed between the outer cover 21 and the lower inner lining 22 along the up and down direction, and the rotating structure 30 is located on one side of the upper half of the arc section 52.

[0043] When the upper cover 10 of the charging case is opened, the upper cover 10 rotates upward with the rotating shaft 32 as the center. The convex part 60 of the rotating block 31 of the upper cover 10 moves along the outer surface of the arc section 52 of the damping member 50. While forcing the damping member 50 to deform towards the inside of the charging case, the damping member 50 generates a reaction force on the upper cover 10. During this process, the user can feel the damping sensation during rotation, the rotation feel is good, and the upper cover 10 and the lower cover 20 are not prone to shaking; the damping structure is simple and convenient to manufacture. When the upper cover 10 is opened and closed to the maximum position, the convex part 60 of the rotating block 31 is exactly located outside the upper half of the arc section 52 of the damping member 50, as Figure 6 shown. When the user takes out the earphone or hearing aid, the damping member 50 prevents the upper cover 10 from falling downward and closing the cover. When the user closes the upper cover 10, the upper cover 10 rotates again along the central position of the rotating shaft 32, and the convex part 60 of the rotating block 31 moves from the upper half of the arc section 52 of the damping member 50 to the lower half. During this process, the damping member 50 will be forced to deform, thereby obtaining a damping sensation. When the upper cover 10 of the charging case is close to the closed state, the suction force between the metal sheet and the magnet of the charging case itself enables the upper cover 10 of the charging case to be firmly adsorbed on the lower cover 20, as Figure 9 shown, thereby preventing the earphone or hearing aid from falling out of the bin during carrying.

[0044] Preferably, when the flipping angle of the upper cover 10 is 20° - 98°, the convex part 60 abuts against the convex surface 521 of the arc section 52, and there is a damping sensation when the upper cover 10 flips relative to the lower cover 20. Since the damping member 50 is a metal elastic sheet, the damping sensation generated by this metal sheet enables a better user experience during the process of the user opening and closing the upper cover of the charging case, and it is more wear-resistant.

[0045] Magnetic attractors that can attract each other, such as magnets, are respectively provided on the upper cover 10 and the lower cover 20; when the flipping angle of the upper cover 10 is less than 20°, the magnets between the upper cover 10 and the lower cover 20 attract each other under the action of magnetic force, enabling the upper cover 10 of the charging case to be firmly adsorbed on the lower cover 20, thereby preventing the earphone or hearing aid from being thrown out of the bin during carrying. At this time, the magnetic force of the magnet plays the role of attracting and closing the upper cover 10 and the lower cover 20, so there should be no damping between the upper cover 10 and the lower cover 20 to weaken the magnetic attraction effect.

[0046] There is still a damping sensation when the upper cover 10 flips by 98°, so as to prevent the upper cover 10 from shaking when flipping from 98° to the maximum opening angle.

[0047] The convex portion 60 of the rotating block 31 may have a protruding length of 3 mm relative to the central axis of the rotating shaft 32, that is Figure 5 and Figure 6 the dimension S in

[0048] so that while achieving rotational damping, the convex portion 60 will not protrude too long to affect the service life. Figure 5 and Figure 6 As shown in

[0049] Figure 5 Figure 6 when flipping, the distance from the edge of the upper cover 10 in contact to the central axis of the rotating shaft 32 is L, and the distance L is about 55 - 57 mm. The protruding length S of the convex portion 60 relative to the central axis of the rotating shaft 32 is about 3 mm. Thus, under the lever action, combined with the damping member 50 being SUS304 stainless steel 3 / 4H, the maximum resistance generated by the upper cover 10 during flipping is 2.3 N. This force provides the most comfortable experience for opening the cover, and this charging case is particularly suitable for the elderly.

[0050] In this embodiment, the damping member 50 is made of SUS304 stainless steel 3 / 4H material, which can generate appropriate resistance and has a better feel for opening. The material of the damping member 50 has been continuously explored by R & D personnel, excluding materials such as stainless steel 304H and stainless steel 301H. Finally, SUS304 stainless steel 3 / 4H is used as the material of the damping member 50 to achieve the effect of balancing the opening feel and manufacturing convenience.

[0051] The upper abutting section 51 and the middle section 53 of the damping member 50 abut against the lower inner lining 22, so as to support the damping member 50 when the convex portion 60 abuts against the convex surface 521 of the arc section 52. The middle section 53 is designed such that its angle is parallel to the surface of the lower inner lining 22, so that the middle section 53 fits more closely with the lower inner lining 22, has a larger contact area, and better support performance.

[0052] The lower mounting section 55 of the damping member 50 is used to pre - fix and mount the damping member 50 on the lower outer cover 21. Two positioning notches 551 are provided on the lower mounting section 55, and two support columns 211 protrude from the inner wall of the lower outer cover 21. The two positioning notches 551 are respectively engaged with the two support columns 211 in a snap - fit manner. Thus, when the damping member 50 is installed on the lower outer cover 21 through the lower mounting section 55, it can be positioned more quickly left and right, and the lower mounting section 55 of the damping member 50 is not easily slipped out of the support columns 211.

[0053] The upper abutting section 51 of the damping member 50 abuts against the lower inner lining 22 and can slide along the surface of the lower inner lining 22. Therefore, after the damping member 50 is stressed, the arc section 52 is squeezed and deformed, causing the upper abutting section 51 to slide and extend along the surface of the lower inner lining 22, thereby increasing the elastic deformation ability of the arc section 52 and improving the feel of opening and closing. And the damping member 50 will not have an overall displacement.A transition section 54 is connected between the middle section 53 and the lower mounting section 55. The transition section 54 is bent relative to the middle section 53 and the lower mounting section 55. The transition section 54 has a first bending angle 541 relative to the middle section 53 and a second bending angle 542 relative to the lower mounting section 55. The first bending angle 541 and the second bending angle 542 are provided with rounded transitions, so that it is not as easy to deform as direct circular arc positioning, and the damping member 50 will not affect its service life after being stressed for a long time; the transition section 54 can also have a pre-tightening force, so that the upper abutting section 51 and the middle section 53 are more closely attached to the lower inner lining 22, and the damping member 50 is not easily deformed. Preferably, the transition section 54 is bent at a bending angle of 45° relative to both the middle section 53 and the lower mounting section 55. In some embodiments, the transition section 54 can also have a micro-wave structure.

[0054] Referring Figure 7 、 11 There are also two positioning shoulders 552 formed on the damping member 50, so that the damping member 50 has an inverted T-shaped structure as a whole, and the width of the lower mounting section 55 is greater than that of the transition section 54; two positioning columns 212 protrude from the inner wall of the lower outer cover 21. After the two positioning notches 551 of the lower mounting section 55 of the damping member 50 are respectively fitted with the two support columns 211, the two positioning shoulders 552 are respectively abutted and fitted with the two positioning columns 212, so as to limit and install the damping member 50 in the lower outer cover 21, and the installation is more stable.

[0055] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them are within the protection scope of the present invention.
