In order to facilitate understanding of the technical solutions of the present application, before writing the embodiments of the present application, a brief introduction is made to the technical background related to the technical solutions of the present application.

Referring to fig. 1, fig. 1 is a schematic 3D structure diagram of a charging box in the prior art provided by the present application, and fig. 1 shows a situation that an earphone is placed in the charging box. As shown in fig. 1, the charging box comprises a rotating shaft 2, a magnet 4 and an earphone slot 3, wherein the rotating shaft 2 is arranged on the rear inner wall of the charging box, the magnet 4 is arranged on the front inner wall of the charging box, or the magnet 4 is arranged close to the front inner wall of the charging box. The earphone slot 3 is located in the middle portion of the case 12, and an earphone is placed in the earphone slot 3. Specifically, the earphone slot 3 in the charging box includes a first earphone slot 31 and a second earphone slot 32, the first earphone slot 31 and the second earphone slot 32 are symmetrically arranged about a central axis of the charging box, a first earphone 51 is placed in the first earphone slot 31, and a second earphone 52 is placed in the second earphone slot 32.

Fig. 2 is a schematic layout diagram of a charging box in the prior art according to an embodiment of the present application. As shown in fig. 2, in the prior art, in the length direction of the charging box, the rotating shaft 2 and the earphone are partially overlapped, the earphone and the magnet 4 are partially overlapped, and the rotating shaft 2 and the magnet 4 are partially overlapped or completely overlapped. Since the shaft 2, the earphone and the magnet 4 have certain widths, for convenience of description, the width of the shaft 2 is referred to as a first width, the width of the earphone is referred to as a second width, and the width of the magnet 4 is referred to as a third width. Since a certain distance is required to be provided between two adjacent components to prevent interference between the two adjacent components, according to the layout shown in fig. 2, the width of the charging box is required to be greater than the sum of the first width, the second width and the third width, that is, the width of the charging box is determined by the width of the rotating shaft 2, the width of the earphone, the width of the magnet 4, the distance between the two adjacent components, the wall thickness of the charging box, and other dimensions.

Note that, in the present embodiment, the first direction F1 refers to the width direction of the charging box, i.e., the vertical direction in fig. 2, and the second direction F2 refers to the length direction of the charging box, i.e., the horizontal direction in fig. 2. In general, the front inner wall surface or the rear inner wall surface of the charging box is perpendicular to the width direction of the charging box, and the embodiment of the present application further explains the above-mentioned partial overlap or full overlap with the rear inner wall surface of the charging box as a reference surface. Since the earphones include the left earphone and the right earphone, the above-mentioned partial overlap between the rotating shaft 2 and the earphone slot 3 means: the projection of the rotating shaft 2 on the inner wall surface of the rear part is overlapped with the projection part of the left earphone on the inner wall surface of the rear part, and/or the projection of the rotating shaft 2 on the inner wall surface of the rear part is overlapped with the projection part of the right earphone on the inner wall surface of the rear part. The partial overlap between the earphone and the magnet 4 means that: the projection of the magnet 4 on the inner wall surface of the rear part is overlapped with the projection part of the left earphone on the inner wall surface of the rear part, and/or the projection of the magnet 4 on the inner wall surface of the rear part is overlapped with the projection part of the right earphone on the inner wall surface of the rear part. The partial overlap or the complete overlap between the rotating shaft 2 and the magnet 4 means that: the projection of the magnet 4 on the rear inner wall surface is partially or completely overlapped with the projection of the rotating shaft 2 on the rear inner wall surface.

Among the prior art scheme, because each part has the condition of overlapping each other in the length direction in the box that charges, the width that leads to charging the box receives the width of pivot 2, the width of earphone and the common influence of the width of magnet 4, leads to charging the box great in the width direction to influence the overall dimension of whole box that charges, lead to its portability relatively poor.

In order to solve the above problems, the present application provides a charging box, which can reduce the length and/or width dimensions of the charging box by improving the layout of each device in the charging box, thereby reducing the external dimensions of the charging box.

Referring to fig. 3, fig. 3 is a schematic 3D structural diagram of a charging box according to an embodiment of the present application. As shown in fig. 3, the charging box includes a box body 12 and a cover 11, wherein the cover 11 is connected to the box body 12 through a rotating shaft 2, so that the cover 11 can rotate around the rotating shaft 2, thereby opening and closing the charging box. The charging box is internally provided with two earphone slots 3 for placing earphones, the shapes of the earphone slots 3 are adapted to the appearance of the earphones, each earphone slot 3 comprises a first earphone slot 31 and a second earphone slot 32, the first earphone slot 31 and the second earphone slot 32 are respectively used for placing a first earphone 51 and a second earphone 52, the first earphone 51 can be a left earphone, and the second earphone 52 can be a right earphone. When the earphone needs to be stored or charged, the earphone is placed in the charging box. In order to ensure the stability of the earphone placed in the charging box, a magnet 4 is also arranged in the charging box. Magnet 4 in the box that charges can with the earphone in magnet 4 or the earphone in the metalwork produce the adsorption affinity between, can assist the user and put into the earphone groove 3 of the box that charges with the earphone more conveniently, simultaneously, adsorb the earphone in the earphone groove 3 in the box that charges, prevent that lid 11 from not covering when on box body 12, the earphone drops in from the box that charges.

Fig. 4 is a schematic layout view of an interior of a charging box according to an embodiment of the present application. As shown in fig. 4, in the embodiment of the present application, when the rotating shaft 2, the earphone slot 3, and the magnet 4 in the charging box are arranged, a staggered arrangement is adopted, so that the rotating shaft 2 and the magnet 4 do not overlap in the length direction of the charging box. That is, in the length direction of the charging box, when the earphone is placed in the charging box, the rotating shaft 2 is partially or completely overlapped with the earphone, the magnet 4 is partially or completely overlapped with the earphone, and the magnet 4 is not overlapped with the rotating shaft 2. With such a layout, the common overlapping part among the three parts of the rotating shaft 2, the earphone and the magnet 4 can be avoided.

Specifically, the earphone slot 3 in the embodiment of the present application includes a first earphone slot 31 and a second earphone slot 32, and when the staggered layout design is performed, in the length direction of the charging box, the first earphone slot 31 and the second earphone slot 32 are disposed along the length direction of the charging box, and the first earphone slot 31 and the second earphone slot 32 are respectively located on two sides of the center line of the charging box. A certain gap is provided between the first earphone slot 31 and the second earphone slot 32 to prevent earphones from being placed in the first earphone slot 31 and the second earphone slot 32 to interfere with each other. When the rotation shaft 2 is disposed, the rotation shaft 2 is disposed to partially overlap or entirely overlap the first earphone slot 31; when the magnet 4 is provided, the magnet 4 is provided so as to partially overlap or entirely overlap the second earphone slot 32.

It should be noted that, taking a preset plane perpendicular to the width direction of the charging box as a projection plane, the above-mentioned partial overlapping or full overlapping of the rotating shaft 2 and the first earphone slot 31 means: the projection of the rotating shaft 2 on the preset plane is partially overlapped or completely overlapped with the projection of the earphones in the first earphone slot 31 on the preset plane, wherein, the complete overlap may refer to the projection of the rotating shaft 2 on the preset plane, and is completely positioned in the projection of the earphones in the first earphone slot 31 on the preset plane. The above-mentioned magnet 4 and the second earphone slot 32 partially overlap or completely overlap means: the projection of the magnet 4 on the preset plane is partially overlapped or completely overlapped with the projection of the earphones in the second earphone slot 32 on the preset plane, wherein, the complete overlap may refer to the projection of the magnet 4 on the preset plane, and is completely positioned in the projection of the earphones in the second earphone slot 32 on the preset plane. The magnet 4 does not overlap the rotating shaft 2, which means that: the projection of the magnet 4 on the preset plane is not overlapped with the projection of the rotating shaft 2 on the preset plane, namely the projections of the two parts on the preset plane do not have an intersection. In addition, it should be noted that the projection of the earphone in the first earphone slot 31 on the preset plane does not overlap with the projection of the earphone in the second earphone slot 32 on the preset plane.

In other words, a plane perpendicular to the length direction of the charging box divides the space inside the charging box into a first region in which the first earphone slot 31 and the rotation shaft 2 are located and a second region in which the second earphone slot 32 and the magnet 4 are located. In the first region, the rotation shaft 2 is disposed on the rear inner wall of the case 12, and the position of the first earphone slot 31 can be adjusted according to the space left in the first region, so that the first region can just receive the rotation shaft 2 and the first earphone slot 31. In the second region, the magnet 4 may be disposed on or near the front inner wall of the case 12, and the position of the second earphone slot 32 may be adjusted according to the space left in the second region, so that the magnet 4 and the second earphone slot 32 can be just received in the second region.

Through the arrangement, the rotating shaft 2 and the second earphone slot 32 are staggered in the length direction of the charging box, the magnet 4 and the first earphone slot 31 are staggered in the length direction of the charging box, and the phenomenon that the rotating shaft 2, the magnet 4 and any one earphone slot 3 form a whole overlapped layout in the length direction of the charging box is avoided. And first earphone groove 31 and second earphone groove 32 need not to form symmetrical overall arrangement, and first earphone groove 31 and second earphone groove 32 can carry out nimble adjustment according to the space in the box that charges, make full use of the space in the box that charges.

In the embodiment of the present application, since the rotating shaft 2 and the magnet 4 are offset in the length direction of the charging box, the size of the charging box in the width direction does not need to consider the width of the rotating shaft 2, the width of the earphone slot 3 and the width of the magnet 4 at the same time.

Specifically, since the rotating shaft 2 and the first earphone slot 31 are located in the first region and the magnet 4 and the second earphone slot 32 are located in the second region, the distance between the devices in the charging box in the width direction and the thickness of the charging box wall are maintained. The size of the charging box in the width direction is determined by the sum of the width of the earphone slot 3 and the width of the rotating shaft 2, or the size of the charging box in the width direction is determined by the sum of the width of the earphone slot 3 and the width of the magnet 4.

In general, the left and right earphones of the earphones are the same-sized earphones, that is, the two earphones have the same specification, and therefore, the first earphone slot 31 and the second earphone slot 32 for placing the earphones are also the same-sized two earphone slots 3. That is, in the embodiment of the present application, the width of the first earphone slot 31 is equal to the width of the second earphone slot 32, and the length of the first earphone slot 31 is equal to the length of the second earphone slot 32. Therefore, when the width of the rotation shaft 2 is greater than the width of the magnet 4, the sum of the width of the first earphone slot 31 and the width of the rotation shaft 2 is greater than the sum of the width of the second earphone slot 32 and the width of the magnet 4, and at this time, the size of the charging box in the width direction is determined by the sum of the width of the first earphone slot 31 and the width of the rotation shaft 2. When the width of the rotation shaft 2 is smaller than the width of the magnet 4, the sum of the width of the first earphone slot 31 and the width of the rotation shaft 2 is smaller than the sum of the width of the second earphone slot 32 and the width of the magnet 4, and at this time, the size of the charging box in the width direction is determined by the sum of the width of the second earphone slot 32 and the width of the magnet 4.

In the conventional technical solution, the size of the charging box in the width direction must simultaneously consider the width of the rotating shaft 2, the width of the earphone slot 3 and the width of the magnet 4, i.e. the charging width must be larger than the sum of the widths of the three. In the charging box provided in the embodiment of the present application, the size of the charging box in the width direction is determined by the width of the rotating shaft 2 and the width of the earphone slot 3, or the width of the magnet 4 and the width of the earphone slot 3. Compared with the conventional technical scheme, the size of the rotating shaft 2 in the width direction or the size of the magnet 4 in the width direction is saved by the width of the charging box in the embodiment of the application. Through the overall arrangement in this application embodiment, can reduce the width dimension of box that charges to be favorable to the miniaturization of box that charges, improve the convenience of carrying of box that charges.

Fig. 5 is a top view of a charging box according to an embodiment of the present application, where the charging box is in an open state, and an earphone is placed in the charging box.

In the embodiment of the present application, as shown in fig. 5, the dimension of the charging box in the length direction of the charging box can also be adjusted by adjusting the position of the earphone slot 3, as shown in fig. 1, when the dimension value of the earphone slot 3 in the length direction of the charging box is the maximum length L _max In the layout of the earphone slots 3 in the embodiment of the present application, referring to fig. 4, compared to the earphone slot 3 shown in fig. 1, the first earphone slot 31 is rotated counterclockwise by α degrees around its own center, and the second earphone slot 32 is also rotated counterclockwise by α degrees around its own center, where a length dimension L of the earphone slot 3 in the length direction of the charging box is smaller than a maximum length L of the earphone slot 3 in the length direction of the charging box _max Therefore, by adjusting the position of the earphone slot 3, the dimension value of the charging box in the longitudinal direction can be adjusted.

It should be noted that when the position of the earphone slot 3 is adjusted to reduce the size value of the charging box in the length direction, the size value of the charging box in the width direction may be caused, and those skilled in the art can adjust the length and the width of the charging box comprehensively according to actual needs.

The shape of the magnet 4 in the embodiment of the present application may be a rectangular parallelepiped shape, a cylindrical shape, or other shapes, and the embodiment of the present application is not particularly limited to the shape.

In the embodiment of the present application, when the magnet 4 and the shaft 2 are disposed, the shaft 2 and the magnet 4 are generally disposed on both sides of the case 12, for example, the shaft 2 is disposed on the inner rear wall of the case 12, and the magnet 4 is disposed on the inner front wall of the case 12. The arrangement of the magnet 4 and the rotating shaft 2 on the two sides of the box body 12 is beneficial to fully utilizing the space in the box body 12, thereby being beneficial to reducing the overall dimension of the charging box.

Based on the same inventive concept, the embodiment of the present application provides an earphone assembly, which comprises an earphone and a charging box, wherein the shape of the earphone is adapted to the shape of an earphone slot 3 in the charging box.
