Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 5, the present embodiment provides a charging box including a lower case 10 having an inner cavity 100, an upper cover 20 mounted on the lower case 10, and a charging assembly 30 mounted in the inner cavity 100.

Wherein, have the inside lining 11 that sets up with this lower casing 10 phase-match on the casing 10 down, have two first cavities 111 that are used for placing the organism of ear-carried hearing aid and be used for placing the second cavity 112 of the sound guide device of ear-carried hearing aid on this inside lining 11, wherein, two first cavities 111 misplace the setting up, down on the homonymy of inside lining 11 to lay side by side with second cavity 112 left and right.

The upper cover 20 is pivotally or covered on the lower housing 10, and the upper cover 20 can cover and seal the inner cavity of the lower housing 10.

The charging assembly 30 comprises a circuit board 31, a battery 32, components mounted on the circuit board 31, and charging contacts 33 extending into the first cavity 111, and since the circuit for charging the battery 32 and charging the hearing aid by the battery 32 is the prior art, a person skilled in the art can select corresponding components to implement corresponding charging functions according to the requirements of the prior art.

The box that charges that this embodiment provided utilizes the shape characteristics of ear back of the body formula audiphone sound pipe (tube), places the organism dislocation of ear back of the body formula audiphone through two first cavities 111, and effective convergence symmetry sets up the problem that leads to the space waste, so can design the volume of the box that charges littleer to in order to portable.

In this embodiment, the side wall 1121 of the second cavity 112 adjacent to the two first cavities 111 is extended along the offset direction of the two first cavities 111, for example, the two first cavities 111 are offset from the lower left to the upper right in fig. 2, so that the second cavity 112 and the adjacent side wall thereof are also extended from the lower left to the upper right, so that the closest distances between the two first cavities 111 and the second cavity are substantially the same, and thus the second cavity 112 with a small volume can be designed to satisfy the sound guiding device of the two hearing aids, thereby further reducing the volume of the charging box.

Preferably, the lower portion of the side wall 1121 of the second cavity 112, which is adjacent to the two first cavities 111, protrudes into the second cavity 112, so that a space recessed toward the second cavity 112 is formed on the back surface of the side wall 1121, and a portion of the battery 32 of the charging assembly 30 is located in the space and is limited by the space, so as to reasonably plan the space occupied by the second cavity 112, further reduce the volume of the charging box, and limit the battery 32, so as to facilitate the assembly of the battery 32.

In this embodiment, the liner 11 has a skirt 113 covering an opening edge of the inner cavity 100, and the skirt 113 can cover a gap between the liner 11 and the lower housing 10 when the liner 11 and the lower housing 10 are assembled, so as to prevent dust from entering the inner cavity 100 and enhance the appearance of the charging box.

In this embodiment, the bottom of the liner 11 has a plurality of positioning posts 114, and the circuit board 31 has positioning holes 310 matching with the positioning posts 114, so that the liner 11 can position and limit the circuit board 31, and the circuit board 31 can be conveniently mounted.

In this embodiment, one of a snap groove and a buckle is respectively disposed on the outer peripheral wall of the liner 11 and the inner peripheral wall of the inner cavity 100, so that the liner 11 can be fixed in the inner cavity 100 in a snap fixing manner, and a simple assembly of fixing between the liner 11 and the lower shell 10 is realized.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
