Technical Field
[0001] The present invention relates to the technical field of charging boxes, and in particular to an earphone charging box for storing and charging Bluetooth earphones. Background Art
[0002] Currently, common wireless earphones are equipped with a charging box (charging compartment) for charging the earphones. The charging box of the earphone is formed with a receiving cavity corresponding to the shape of the earphone, and two elastic electrodes for contact charging are arranged in the receiving cavity. When the earphone is placed in the receiving cavity of the charging box, the charging electrode of the earphone contacts the elastic electrode for charging.
[0003] Usually, in order to improve the opening and closing damping of the charging box, a torsion spring is usually configured at the junction of the cover and the box body of the charging box. The torsion spring provides elastic force to keep the charging box in the open and closed states. Since the torsion spring requires a certain amount of space, there is not enough space for some charging boxes with larger horizontal dimensions and smaller vertical dimensions.
[0004] In addition, there are also methods that use magnetic attraction to keep the charging box in a closed state. However, it is difficult for magnetic attraction to keep the cover in an open state. That is, when the cover is in an open state, the state between the cover and the box body is unstable, and the cover is likely to close automatically. Summary of the invention

DETAILED DESCRIPTION
[0018] The present invention is a charging box for storing and charging earphones. Figures 1 to 6 As shown, the present invention comprises: a cover body 10 and a box body 30 , wherein the cover body 10 and the box body 30 are pivotally connected to each other to realize the opening and closing of the cover body 10 relative to the box body 30 .
[0019] The cover body 10 adopts a double-layer composite structure, which includes a cover outer shell 1 and a cover inner shell 2, that is, after the cover outer shell 1 and the cover inner shell 2 are processed separately, they are fixedly connected by means of a snap-fit connection or a buckle connection.
[0020] The box body 30 adopts a three-layer composite structure, which includes: a box body outer shell 3, a box body middle shell 4 and a box body inner shell 5. The box body outer shell 3 and the box body inner shell 5 are respectively fixedly connected to the upper and lower sides of the box body middle shell 4 by means of snap fitting, buckle or other connection methods.
[0021] The cover inner shell 2 is formed with a pivoting portion 21 protruding outward. The box inner shell 5 is formed with a mounting portion 51 at a position corresponding to the pivoting portion 21, and the pivoting portion 21 and the mounting portion 51 are connected via a pivot.
[0022] Specifically, the pivotal portion 21 is formed by protruding outward from the side of the cover inner shell 2. A pivot hole 211 is provided on both sides of the pivotal portion 21; an abutment portion 212 parallel to the pivot hole 211 is formed at one end of the pivotal portion 21 away from the cover inner shell 2. The abutment portions 212 are symmetrically provided on both sides of the pivotal portion 21, and the abutment portions 212 are arc surfaces for easy rotation. A limited position convex strip 213 is provided along the inner side of the pivotal portion 21 and between the two abutment portions 212.
[0023] The mounting portion 51 is a notch formed along the side of the inner shell 5 of the box body, and pivot seats 511 are respectively provided on both sides of the mounting portion 51. During assembly, the pivot portion 21 is located between the two pivot seats 511, and then the pivot is inserted into the pivot seats 511 along the pivot hole 211.
[0024] Abutment plates 512 are respectively arranged at positions corresponding to the abutment portions 212 between the two pivot seats 511. The abutment plates 512 are integrally formed from the inner wall of the inner shell 5 of the box body from top to bottom. The abutment plates 512 are used to provide elastic damping and provide elastic force through their own elastic deformation.
[0025] In addition, a limit slot 513 is formed downward along the edge of the inner shell 5 of the box body, which can cooperate with the limit convex strip 213. Figure 4 As shown, when the cover is at the maximum opening angle relative to the box body, the limiting convex strip 213 just falls into the limiting slot 513, thereby limiting the rotation angle and forming the maximum opening angle of the cover. At the same time, the abutting portion 212 presses against the abutting plate 512, and the elastic force generated by the elastic deformation of the abutting plate 512 allows the cover to be stably maintained at the maximum opening angle state, preventing the cover from accidentally closing due to its own rotation.
[0026] The lid and the box body are stably kept in the closed state by magnetic force. The lid inner shell 2 and the box inner shell 5 are respectively formed with an upper docking plane 24 and a lower docking plane 54 on the side away from the pivoting portion. An upper magnet 240 is arranged on the inner side of the lid inner shell 2 corresponding to the position of the upper docking plane 24; and a lower magnet 540 is arranged on the lower side of the box inner shell 5 corresponding to the position of the lower docking plane 54. When the lid and the box body are in the closed state, the lid and the box body are kept in the closed state by the magnetic adsorption of the upper magnet and the lower magnet.
[0027] The present invention also includes a charging circuit unit 6, which is arranged in the interval between the inner shell 5 of the box body and the middle shell 4 of the box body. The charging circuit unit 6 includes a rechargeable battery 61 and a charging coil 62. The charging coil 62 is for wireless charging. The rechargeable battery and the charging coil are stacked up and down, and a hollow opening 42 is formed on the middle shell 4 of the box body corresponding to the position of the charging coil 62, and the isolation of wireless charging is reduced by the hollow opening 42.
[0028] The inner shell 5 of the box body has a receiving cavity 52 for placing the charged product, and a charging electrode 521 connected to the charging circuit unit 6 is provided at the receiving cavity 52. A positioning recess 22 is formed on the cover body shell at a position corresponding to the receiving cavity 52. The earphone product is positioned from the upper and lower directions through the receiving cavity 52 and the positioning recess 22. A magnet for adsorbing the charged product is provided at a position corresponding to the receiving cavity 52 on the inner side of the inner shell 5 of the box body.
[0029] The present invention is not only applicable to earphones, but also to other electronic products. Of course, the above description is only a specific embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention should be included in the scope of the present invention.
