Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

As used herein, "wireless headsets" (or TWS headsets for short) include, but are not limited to, devices using bluetooth technology, infrared technology, 2.4G wireless technology. Wireless headsets are generally divided into three parts: the first part is a sound source, the second part is a receiver, and the third part is an earphone part, wherein the function of the first part is mainly to convert signals transmitted by a mobile phone or the receiver into sound and transmit the sound to the ears of a person. The wireless earphone general matching sleeve is provided with a corresponding wireless earphone charging box, electric energy can be stored in the charging box, and the wireless earphone is charged while the wireless earphone is stored.

The inventor finds that most wireless earphone charging boxes adopt a flip structure through long-term research, and the flip structure comprises a cover body, a bottom shell and a rotating shaft structure, wherein the cover body and the bottom shell are turned over through the rotating shaft structure so as to open or close the charging box. In order to realize the consistency of the appearance of the charging box, the area of the bottom shell corresponding to the position of the rotating shaft is thinner than other areas, so that the structural strength of the area of the bottom shell corresponding to the position of the rotating shaft is weaker, and the bottom shell is easily broken due to improper force when the charging box is actually opened.

Based on this, the bottom case of some charging boxes is made into an MIM (Metal injection Molding) in a region corresponding to the rotation shaft, so as to improve the overall structural strength of the bottom case corresponding to the rotation shaft. However, the MIM process is expensive and not easy to popularize. Some charging boxes are fixed to the bottom shell by disassembling a metal part at the rotating shaft, and the rotating shaft penetrates through the metal part so as to strengthen the overall structural strength of the bottom shell corresponding to the position of the rotating shaft. However, this method of increasing the structural strength is achieved by adding a metal bracket, which obviously increases the cost. Simultaneously, still increaseed the box pivot tolerance chain that charges, can bring adverse effect for the box assembly time tolerance management and control that charges, the tolerance of the box that charges of later stage mass production is difficult to the management and control.

In order to solve the above technical problem, this embodiment provides an earphone charging box to promote the structural strength that the drain pan corresponds the pivot position under the prerequisite that hardly increases the cost and do not increase the tolerance management and control degree of difficulty, and then reduce when flip owing to exert oneself improper risk that causes the drain pan to break.
