Referring to Figures 1-5, a first aspect of the present disclosure provides a charging box 100, including a first lower case 1, a second lower case 2, a sealing layer (not shown) and a mainboard (not shown). The first lower shell 1 includes a first shell wall 11 , an opening 12 surrounded by the first shell wall 11 , and an annular boss 13 extending from the first shell wall 11 toward the middle of the opening 12 . The second lower shell 2 is at least partially located in the opening 12 . The second lower shell 2 includes a sealing surface 26 facing the bottom of the opening 12 . The sealing surface 26 and the annular boss 13 are away from the first surface of the bottom of the opening 12 . 131 Relative settings. The sealing layer is disposed between the first surface 131 and the sealing surface 26 and is connected with the sealing surface 26 and the first surface 131 to form a sealing connection between the first lower housing 1 and the second lower housing 2 . The second lower housing 2 and the sealing layer close a part of the opening 12 to form a sealed cavity, and the main board is arranged in the sealed cavity. In some embodiments, the first surface 131 and the sealing surface 26 are parallel and perpendicular to the depth direction of the opening cavity 12 , or may be at a certain angle with the depth direction of the opening cavity 12 , such as 5°, 10°, etc., the present disclosure does not not limited. For convenience of explanation, the present disclosure sets reference directions, where the first direction X is the width direction of the charging box 100, the second direction Y is the thickness direction of the charging box 100, and the third direction Z is the height direction of the charging box 100, where The depth direction of the oral cavity 12 is parallel to the third direction Z.

Specifically, when the second lower housing 2 is assembled with the first lower housing 1 along the third direction Z, the sealing surface 26 is connected to the sealing layer provided on the first surface 131 of the annular boss 13, The second lower case 2 and the sealing layer can close the lower half of the opening 12 to form an independent sealed cavity separated from the outside, through which the motherboard is accommodated. The sealing layer is connected to the sealing surface 26 and the first surface 131 respectively, and forms an annular sealing plane surrounding the opening 12 in the opening 12 through "surface-to-surface" contact. In this way, liquid, dust and other substances can be prevented from flowing into the sealed cavity through the gap between the first lower case 1 and the second lower case 2, which is conducive to waterproof protection of the motherboard in the sealed cavity and improves the performance of the charging box 100. The waterproof performance helps extend the service life of the charging box 100.

The sealing layer may be formed by a dispensing sealing process or by applying glue, which is not limited by this disclosure. In an embodiment in which the first surface 131 of the annular boss 13 is inclined with the third direction Z, when forming the sealing layer through a dispensing process, the placement angle of the charging box 100 can be appropriately adjusted so that the first surface The dispensing positions of 131 and sealing surface 26 are flush with the horizontal plane, and the placement angle of the charging box 100 is continuously adjusted until a sealing layer is formed on the entire annular boss 13 . In this way, the level of the dispensing surface can be ensured when dispensing glue, and the uneven thickness of the sealing layer or the overflow of glue caused by gravity can be avoided. Similarly, when the sealing layer is formed by applying glue, the angle of the first lower housing 1 can also be rotated so that the glue covers the first surface 131 with a uniform thickness, and then the sealing surface of the second lower housing 2 is pressed against the first surface 131 . against the first surface 131, thereby achieving a sealed connection. In other embodiments, the sealing layer is also provided between the first shell wall 11 and the second shell wall 22 of the first lower shell 1 and the second lower shell 2, for example, on the wall surface parallel to the third direction Z. to further improve the sealing performance of the charging box 100.

In some embodiments, the annular boss 13 and the first lower shell 1 are integrally formed to avoid a gap between the annular boss 13 and the first lower shell 1 so that liquid and other substances can flow into the seal through the gap. cavity, affecting the waterproof performance of the charging box 100. In addition, the annular boss 13 can be disposed in a close position so that the sealing surface 26 can contact the sealing layer at a position close to the end surface 17 of the first shell wall 11 without affecting the sealing layer, the annular boss 13 and the second shell wall 11 . The sealed connection formed between the two lower housings 2 can also reduce the material used in the second lower housing 2, which not only reduces the cost, but also reduces the overall weight of the charging box 100 and improves portability.

The charging box 100 of the present disclosure may be a wireless earphone charging box 100, a portable mobile phone charging box 100, a wireless landline charging box 100, a tablet charging box 100, etc., and the disclosure is not limiting. In addition, the charging box 100 can be a small portable charging box 100 or a larger charging box 100, which is not limited by this disclosure. The second lower housing 2 includes a second housing wall 22 and an accommodating cavity 23 surrounded by the second housing wall 22 . The accommodating cavity 23 is used to accommodate the equipment to be charged that is matched with the charging box 100 . When the device to be charged needs to be charged or does not need to be used, the device to be charged can be placed in the accommodation cavity 23 to perform the charging function and at the same time realize the storage function of the device to be charged.

It should be noted that the mainboard of the present disclosure refers to the circuit structure accommodated in the sealed cavity, including printed circuit boards, flexible circuit boards, soft-hard circuit boards, etc., and the present disclosure is not limiting. As long as a certain component has a connection relationship with a certain circuit board in the accommodation cavity 23, it is referred to as being connected to the motherboard in this disclosure.

In some embodiments, the second lower housing 2 is in contact with the end surface 17 of the first housing wall 11 , and the end surface 17 of the first housing wall 11 is inclined relative to a plane perpendicular to the height direction of the first lower housing 1 . Specifically referring to FIG. 1 , the first wall 111 and the second wall 112 are two walls of the first lower housing 1 perpendicular to the second direction Y, and the height of the first wall 111 in the third direction Z is It is greater than the height of the second wall 112 in the third direction Z, so that the end surface 17 of the first shell wall 11 forms a certain angle with the plane perpendicular to the third direction Z. In this way, the entire first shell wall 11 is in the form of an inclined opening in the second direction Y, thereby exposing the second lower shell 2 accommodated in the opening 12 to a greater extent, and thereby more conveniently exposing the second lower shell 2 accommodated in the opening 12 . The charging device is put into the accommodation cavity 23 , or the device to be charged is taken out from the accommodation cavity 23 . Moreover, since the second lower case 2 is exposed to a greater extent, it is convenient for the user to wipe the accommodation cavity 23 from the outside, which not only improves the overall hygiene of the charging box 100, but also allows the user to wipe the accommodation cavity 23 through the outside when there is liquid in the accommodation cavity 23. Wiping prevents liquid from remaining in the containing cavity 23 and then entering the sealed cavity, causing corrosion to the motherboard or short-circuiting the motherboard.

In some embodiments, the second lower housing 2 includes a side opening 29 provided on the second housing wall 22 , and the side opening 29 is connected to the accommodation cavity 23 . Specifically referring to Figure 1, the side opening 29 is provided on the surface of the second lower housing 2 perpendicular to the second direction Y, fully exposing the accommodation cavity 23, so that the user can put the device to be charged into the accommodation cavity 23 from multiple directions, or put the device into the accommodation cavity 23 from multiple directions. It is taken out of the receiving chamber 23 . In an embodiment where the device to be charged is an earphone, the accommodation cavity 23 corresponding to the side opening 29 can be used to accommodate the earphone handle part of the earphone, and the upper part of the accommodation cavity 23 in the third direction Z can be used to accommodate the earphone head part.

In some embodiments, the first surface 131 is also arranged at an angle relative to the plane perpendicular to the height direction of the first lower housing 1 , which can not only reduce the volume of the second lower housing 2 disposed in the opening 12 , but also reduce charging. The weight of the box 100 can also increase the volume of the sealed cavity, so that the sealed cavity can accommodate as many motherboards as possible, which is beneficial to improving the functionality of the charging box 100 .

Furthermore, in other embodiments, the end surface 17 and the first surface 131 are inclined in the same direction, and at least part of the end surface 17 coincides with the first surface 131 . Specifically referring to Figure 1, at the second wall 112, in this embodiment, the end surface 17 coincides with the first surface 131, further reducing the volume of the second lower housing 2 disposed in the opening 12, and at the same time, compared with the end surface In the embodiment where 17 and the first surface 131 do not overlap, the volume of the sealed cavity is further increased.

When the end surface 17 of the first shell wall 11 is inclined relative to the plane perpendicular to the height direction of the first lower shell 1, an annular boss 13 is additionally provided in the opening 12, so that the ring can be adjusted. The inclination angle between the first surface 131 of the annular boss 13 and the plane perpendicular to the height direction of the first shell wall 11 is used to adjust the process difficulty of dispensing glue to form the sealing layer. For example, the first surface 131 of the annular boss 13 can be The inclination angle between the planes perpendicular to the height direction of the first shell wall 11 is set to be smaller than the inclination angle of the end face 17 of the first shell wall 11, thereby reducing the process difficulty, which is conducive to maintaining a relatively large inclination angle of the end face 17. The process difficulty is reduced, and the annular boss 13 is located inside the opening 12 and away from the outside relative to the end face 17 of the first shell wall 11 , which is more conducive to waterproofing.

In some embodiments, the first lower housing 1 includes a first groove body 113 that is recessed inwardly from the end surface 17 of the first shell wall 11 , and the second lower housing 2 includes a second groove body 113 provided corresponding to the first groove body 113 . Tank 25. The charging box 100 also includes an upper housing (not shown) and a rotating shaft (not shown). The rotating shaft is fixedly connected to one of the upper housing and the first lower housing 1 and is rotationally connected to the other, so that it can be opened and closed for charging. Box of 100. The first groove body 113 and the second groove body 25 avoid the upper housing when the upper housing rotates relative to the first lower housing 1, providing a rotation space for the upper housing to pivot open and close. The rotating shaft can be fixedly provided on the side wall of the first tank body 113, or can be fixedly provided on the upper housing, which is not limited by this disclosure.

Similarly, in other embodiments, the rotating shaft may also be fixedly connected to one of the upper housing and the second lower housing 2 and rotationally connected to the other side. The first groove body 113 and the second groove body 25 are in The upper housing avoids the upper housing when rotating relative to the second lower housing 2 . The rotating shaft may also be fixed on the side wall of the second tank body 25, or may be fixed on the upper housing, which is not limited by this disclosure. The arrangement of the first groove body 113 and the second groove body 25 enables the upper housing to have sufficient rotational stroke when pivoting to open the charging box 100, thereby exposing the second lower housing 2 to a greater extent for convenience. The charging device is put into or taken out of the accommodation cavity 23 .

For production convenience, aesthetic needs and sealing performance requirements, the first lower shell 1 is usually integrally formed in a mold to realize the integral molding of the first shell wall 11 and the annular boss 13. End face 17 is set as the parting surface. However, in the embodiment in which the end surface 17 of the first shell wall 11 is inclined to a plane perpendicular to the third direction Z, because the end surface 17 of the first shell wall 11 is inclined and the annular protrusion provided in the first lower shell 1 There is also an angle between the table 13 and the wall surface of the opening 12. Therefore, during the demoulding process of the first lower shell 1, the annular boss 13 is difficult to demould, the annular boss 13 is damaged during the demoulding process, etc. question. After a large number of calculations and production experiments, the inventor found that setting the length of the annular boss 13 extending from the first shell wall 11 toward the middle of the opening 12 to be greater than or equal to 0.3 mm and less than or equal to 0.7 mm can effectively It can effectively avoid problems such as the first lower shell 1 sticking to the mold and being difficult to demold during the production process, and it can also avoid the sealing plane between the first surface 131 of the annular boss 13 and the sealing layer caused by the extension length of the annular boss 13 being too short. The area is too small and the sealing performance is not good. By reasonably setting the extension length of the annular boss 13, the present disclosure can ensure the maximum sealing plane area of the first surface 131 and the sealing surface 26 as much as possible while avoiding processing difficulties, and ensure the sealing performance of the annular boss 13.

In order to further keep the first lower case 1 and the second lower case 2 relatively fixed, and thereby maintain the contact between the sealing surface 26 and the first surface 131 and the sealing layer, thereby maintaining the sealing performance of the charging box 100, in some embodiments , the first lower housing 1 includes a first buckle 14 provided on the first shell wall 11 , and the second lower housing 2 includes a second buckle 21 that is engaged with the first buckle 14 .

When the first lower housing 1 and the second lower When the housing 2 is assembled in place, the first buckle 14 is stuck in the second buckle 21, making it difficult for the first lower housing 1 and the second lower housing 2 to move relative to each other, thus ensuring that the sealing surface 26 and the first lower housing 2 are properly aligned. The continuous contact between surfaces 131 ensures the sealing performance of the sealing cavity.

It should be noted that in the drawings, the first buckle 14 is configured as a convex rectangular parallelepiped, and the second buckle 21 is configured as a square groove that matches the protrusion. This should be used as an example rather than a limitation. It may be the third buckle 14 . One buckle 14 is configured as a groove of any shape, and the second buckle 21 is configured as a protrusion that matches the groove, which is not limited by this disclosure.
