[0030] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0032] like Figure 1-11 As shown, this embodiment provides a charging box 1 with a damping structure, including an upper cover 10 and a lower cover 20. A receiving cavity 21 is formed in the lower cover 20. 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 box 1 for charging rechargeable devices such as earphones. As for the charging circuit, it is a well-known technology and will not be described in detail 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 be turned relative to the lower cover 20. Figure 5 , 7 As shown, under the action of external force, the upper cover 10 is flipped open relative to the lower cover 20 through the rotating structure 30 to expose the accommodating 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 box 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 box 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 box 1 may be provided with a convex portion 60, and the lower cover 20 may be provided with a damping member 6.

[0035] like Figure 4-Figure 6 As shown, in this embodiment, the damping member 50 of the charging box 1 is arranged on the lower cover 20 , and the protrusion 60 is arranged on the upper cover 10 .

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

[0037] The damping member 50 is arranged in the cavity formed between the lower outer cover 21 and the lower lining 22. The damping member 50 includes an upper abutting section 51, an arc section 52, an intermediate section 53, a transition section 54 and a lower mounting section 55 which 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 with an arc surface in a direction away from the lower 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 the damping member 50. The damping member 50 is made of an elastic material. For example, the damping member 50 is a metal spring, specifically, it can be made of stainless steel or carbon spring steel.

[0038] The arc section 52 of the damping member 50 can be formed by pressing an arc structure from a metal sheet through a stamping die, for example, a 0.3 mm metal sheet. The arc structure can be, for example, a semicircle, 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 passing through the rotating block 31 in a horizontal direction; 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 set 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 configuration of the rotating structure 30 enables the upper cover 10 to be flipped relative to the lower cover 20.

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

[0041] The damping member 50 is disposed on one side of the rotating structure 30. The lower end of the upper cover 10 is provided with a rotating block 31 extending downward, and the bottom of the rotating block 31 is provided with the convex portion 60 extending downward. When the upper cover 10 is flipped open relative to the lower cover 20, the convex portion 60 rotates with the rotating block 31 around the pivot center axis of the rotating shaft 32, and the convex portion 60 can rotate to abut against the convex surface 521 of the arc segment 52.

[0042] It is defined that the upper cover 10 is located above the lower cover 20, and 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 lining 22 along the up and down directions, and the rotating structure 30 is located on one side of the upper half of the arc segment 52.

[0043] When the upper cover 10 of the charging box is opened, the upper cover 10 rotates upward with the rotating shaft 32 as the center, and the convex portion 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, forcing the damping member 50 to deform toward the inside of the charging box. At the same time, the damping member 50 generates a reaction force on the upper cover 10. In this process, the user can feel the damping feeling during rotation, the rotation feel is good, and the upper cover 10 and the lower cover 20 are not easy to shake; the damping structure is simple and easy to manufacture. When the upper cover 10 is opened and closed to the maximum position, the convex portion 60 of the rotating block 31 is just outside the upper half of the arc section 52 of the damping member 50, such as Figure 6 As shown, when the user takes the earphones or hearing aids, the damping member 50 prevents the upper cover 10 from falling down and closing the cover. When the user closes the upper cover 10, the upper cover 10 rotates again along the center position of the rotating shaft 32, and the protrusion 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. In this process, the damping member 50 is forced to deform, thereby obtaining a damping feeling. When the upper cover 10 of the charging box is close to the closed state, the suction force of the metal sheet and the magnet of the charging box itself allows the upper cover 10 of the charging box to be firmly adsorbed on the lower cover 20, as shown in FIG. Fig. 9 As shown, the earphones or hearing aids are prevented from falling out of the compartment during carrying.

[0044] Preferably, when the flip angle of the upper cover 10 is 20° to 98°, the convex portion 60 abuts against the convex surface 521 of the arc segment 52, and the upper cover 10 has a damping feeling when flipping relative to the lower cover 20. Since the damping member 50 is a metal spring sheet, the damping feeling generated by the metal sheet enables the user to obtain a better user experience and is more wear-resistant when opening and closing the upper cover of the charging box.

[0045] The upper cover 10 and the lower cover 20 are provided with magnetic objects that can attract each other, such as magnets; when the flip 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, so that the upper cover 10 of the charging box can be firmly adsorbed on the lower cover 20, thereby preventing the earphones or hearing aids from falling out of the compartment during carrying. At this time, the magnetic force of the magnets attracts each other and closes 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 feeling when the upper cover 10 is turned over 98°, thereby preventing the upper cover 10 from shaking when it is turned over 98° to the maximum opening angle.

[0047] The protrusion 60 of the rotating block 31 may have a protrusion length of 3 mm relative to the central axis of the rotating shaft 32, that is, Figure 5 and Figure 6The dimension S in the middle is such that rotation damping is achieved while the protrusion 60 does not protrude too long and thus affect the service life.

[0048] like Figure 5 and Figure 6 As shown in the figure, the distance from the edge of the upper cover 10 that is in contact with the center axis of the rotating shaft 32 during flipping is L, and the distance L is about 55-57mm. The protruding length S of the protrusion 60 relative to the center axis of the rotating shaft 32 is about 3mm. Therefore, under the action of the lever and combined with the damping member 50 being SUS304 stainless steel 3 / 4H, the maximum resistance generated by the upper cover 10 during flipping is 2.3N. This force is the most comfortable cover opening feeling. The charging box is particularly suitable for use by the elderly.

[0049] In this embodiment, the damping member 50 is made of SUS304 stainless steel 3 / 4H, which can generate appropriate resistance and provide a better opening feel. The material of the damping member 50 has been continuously explored by the R&D personnel, and materials such as stainless steel 304H and stainless steel 301H have been excluded. Finally, SUS304 stainless steel 3 / 4H is used as the material of the damping member 50, which achieves the effect of taking into account both the opening feel and the manufacturing convenience.

[0050] The upper abutting section 51 and the middle section 53 of the damping member 50 abut against the lower lining 22, so that the damping member 50 is supported when the convex portion 60 abuts against the convex surface 521 of the arc section 52. The middle section 53 is designed to have an angle parallel to the surface of the lower lining 22, so that the middle section 53 fits the lower lining 22 better, the contact area is larger, and the supporting performance is better.

[0051] The lower mounting section 55 of the damping member 50 is used to pre-fix the damping member 50 on the lower outer cover 21. The lower mounting section 55 is provided with two positioning notches 551, and two supporting columns 211 protrude from the inner wall of the lower outer cover 21. The two positioning notches 551 are respectively engaged with the two supporting columns 211, so that when the damping member 50 is installed on the lower outer cover 21 through the lower mounting section 55, it can be positioned left and right more quickly, and the lower mounting section 55 of the damping member 50 is not easy to slide out of the supporting columns 211.

[0052] The upper abutting section 51 of the damping member 50 abuts against the lower lining 22 and can slide along the surface of the lower lining 22. Therefore, when the damping member 50 is subjected to force, the arc section 52 is squeezed and deformed, so that the upper abutting section 51 slides and extends along the surface of the lower lining 22, thereby increasing the elastic deformation capacity of the arc section 52 and improving the opening and closing feel. The damping member 50 will not be displaced as a whole.

[0053] 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 set to be rounded transitions, so that it will not be as easy to deform as direct arc positioning, and the damping member 50 will not be affected in service life after being subjected to stress 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 lining 22, and the damping member 50 is not easily deformed. Preferably, the transition section 54 is bent at a 45° bending angle relative to 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] Reference Figure 7 , 11 Two positioning shoulders 552 are also formed on the damping member 50, so that the damping member 50 is an inverted T-shaped structure as a whole, and the width of the lower mounting section 55 is greater than the transition section 54; two positioning columns 212 protrude from the inner wall of the lower outer cover 21, and after the two positioning notches 551 of the lower mounting section 55 of the damping member 50 are respectively matched with the two support columns 211 for installation, the two positioning shoulders 552 are respectively abutted against the two positioning columns 212, so that the damping member 50 is limitedly installed 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, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
