Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone shell technology, specifically to a headphone shell assembly. Background Technology
[0002] With the continuous advancement of technology and people's increasing demands for audio experience, headphones have become an indispensable electronic device in people's daily lives. From the initial wired headphones to today's wireless headphones, headphone technology has undergone many changes, and the market offers a wide variety of headphone products, including in-ear, over-ear, and semi-in-ear models, to meet the needs of different users.
[0003] Earphone cases are typically cases for storing and charging earphones. However, existing earphone cases are usually secured by magnets. This method is relatively loose, and if the earphone case is accidentally dropped, the earphones can easily fall out, causing damage and reducing their lifespan. Utility Model Content
[0004] The purpose of this utility model is to provide an earphone shell assembly that has the advantages of quick opening and closing of the earphone shell and stable fixation, thus solving the problem that the earphones may fall off and be damaged when the current magnetic earphone shell is accidentally dropped.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an earphone shell assembly, including a base, a top cover rotatably connected to one side of the top of the base, and a limiting mechanism for fixing the top cover on the other side. The base includes a housing, and two fitting grooves are symmetrically recessed on the upper surface of the housing. The two fitting grooves are interconnected, and a charging slot is provided on one side of each fitting groove. Two sliding grooves are symmetrically provided on the upper surface of the housing away from the top cover. The top cover includes a flip cover, and an elastic hinge connected to the housing is provided at the bottom of the flip cover.
[0006] Preferably, the top edge of the outer surface of the housing is recessed inward to form a recessed groove for the flap to fit.
[0007] Preferably, the elastic hinge has a transparent observation window inside, and the outer edge of the flip cover facing the housing has an edge that fits against the outer edge of the housing.
[0008] Preferably, the limiting mechanism includes a slider, the top of which is symmetrically provided with two fixing mechanisms extending out of the groove, and the bottom of the slider is provided with a driven plate, and the bottom of the driven plate away from the top cover is provided with a connecting plate.
[0009] Preferably, one side of the connecting plate is fixedly connected to the driven plate, and the other side extends out of the outer edge of the housing and is equipped with a sliding plate. The outer edge of the sliding plate is provided with a plurality of anti-slip strips at equal intervals.
[0010] Preferably, a spring is provided on one side of the driven plate, and round rods are provided at both ends of the slider, with a magnetic block provided on the side of each round rod away from the slider.
[0011] Preferably, each of the fixing mechanisms includes a short column, and each short column has a protruding column on one side, and the top of the short column and the protruding column are provided with an arc-shaped guide surface.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model includes a housing, a flip cover, a slider, a driven plate, a spring, a connecting plate, a sliding plate, and a fixing mechanism. The fixing mechanism, which is slidably installed in the slide groove, is embedded in the flip cover to fix the housing and the flip cover. When disassembling, pulling the sliding plate moves the driven plate and the slider, releasing the fixation of the flip cover and the fixing mechanism. This allows for quick and easy opening of the flip cover and removal of the earphones. It also facilitates quick opening and closing of the earphone shell and easy removal of the earphones. Furthermore, the earphones will not fall off when the earphone shell is dropped.
[0014] 2. This utility model achieves the following effect through its design: the shell, flip cover, elastic hinge, slider, driven plate, spring, round rod, and magnetic block are designed so that the magnetic blocks at both ends of the round rod attract the flip cover, allowing for quick fixation of the flip cover. When disassembling, pulling the slider causes the round rod to displace the two magnetic blocks from the magnetic blocks inside the flip cover, and the elastic hinge causes the flip cover to rotate, allowing for quick opening of the earphone shell.
