Description

Technical Field

[0001] The utility model relates to the technical field of earphone equipment, and in particular to a light leakage-proof charging box and an earphone assembly. Background Art

[0002] To indicate whether the charging box is charging, most charging boxes are equipped with an indicator light, which is then directed to the outer surface of the charging box via a light guide. Existing charging boxes do not shield the light guide. Therefore, when the indicator light is on, not only does the light guide itself glow, but the surrounding charging boxes also emit light (a phenomenon commonly known as "light leakage"). This results in the light guide itself being less than bright, the indication effect being unclear, and the overall appearance being poor.

[0003] Therefore, it is necessary to improve the existing charging box to solve the problem of light leakage at its light guide.

[0004] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0005] One purpose of the present invention is to provide a light leakage-proof charging box and earphone assembly, which can effectively solve the problem that the light guide of the existing charging box is prone to light leakage.

[0006] To achieve the above objectives, the present invention provides a light leakage-proof charging box, comprising:

[0007] A charging box body, the charging box body being provided with a box body accommodating cavity and a box body light exit hole connecting the box body accommodating cavity to the external space of the charging box body;

[0008] A light shield, the light shield being provided with a light shielding chamber and a cover body through hole communicating the light shielding chamber with the light exit hole of the box body;

[0009] A light guide is located in the light-shielding chamber and extends into the light-emitting hole of the box body through the through hole of the cover body.

[0010] Optionally, the light shield is clamped on the inner side of the box body accommodating cavity.

[0011] Optionally, two oppositely arranged L-shaped baffles protrude from the inner wall of the box body accommodating cavity, and the light shield is clamped between the two L-shaped baffles.

[0012] Optionally, a circuit board is also included above the two L-shaped baffles.

[0013] Optionally, an indicator light is provided at the bottom of the circuit board;

[0014] A light-inlet window is provided above the light-shielding chamber at a position corresponding to the indicator light.

[0015] Optionally, a support plate is protruded from the inner wall of the box body accommodating cavity for supporting the light shield upward.

[0016] Optionally, the light guide member includes a U-shaped portion located in the light-shielding chamber and a long straight portion passing through the through hole of the cover body.

[0017] On the other hand, an earphone assembly is provided, comprising two earphone bodies and any one of the aforementioned light leakage-proof charging boxes.

[0018] The beneficial effects of the present invention are to provide a light leakage-proof charging box and earphone assembly, when the indicator light is on:

[0019] First, the light shines downward into the light-shielding chamber through the light-inlet window, so the space outside the light-shielding chamber cannot receive the bright light;

[0020] Then, after the U-shaped portion of the light guide located in the light-shielding chamber is illuminated, the light will be led outward through the long straight portion; and in the process of light transmission, the U-shaped portion and the long straight portion are always wrapped by the light-shielding cover, so no light will be emitted to the surrounding positions. In the end, only the end face of the long straight portion extending to one end of the charging box body will have light, thereby ensuring that the light source is clear and the indication is clear.

[0021] Therefore, the light leakage-proof charging box and earphone assembly provided by the present invention can effectively solve the problem that the light guide parts of the existing charging box are prone to light leakage. BRIEF DESCRIPTION OF THE DRAWINGS
