Description

Technical Field

[0001] The utility model relates to the technical field of headphones, in particular to a headphone with a protective structure. Background Art

[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Headphones can be separated from the media player and connected using only one plug, so you can listen to the audio without disturbing others. They can also isolate the sounds of the surrounding environment, which is very helpful for people who use them in noisy environments such as recording studios, bars, travel, and sports.

[0003] Currently, there are many types of headphones, which are divided into wired and wireless headphones. Wireless headphones use built-in batteries, so a charging port will be provided at the bottom. For example, Chinese patent publication number "CN214014464U" discloses a true wireless headphone, which includes a first headphone body, a second headphone body, a first earmuff, a second earmuff and a head-mounted bracket. The second headphone body is connected to the first headphone body via Bluetooth; a first mounting position is provided in the first earmuff, and the first headphone body is provided on the first mounting position; a second mounting position is provided in the second earmuff, and the second headphone body is provided on the second mounting position; the head-mounted bracket is connected to the first earmuff and the second earmuff.

[0004] The charging port of current Bluetooth headsets usually does not have a protective structure when in use. It will be directly exposed to the outside during long-term use, and dust is easy to enter the inside of the charging port. If it is not cleaned for a long time, it will cause poor contact between the charging port and the charging cable, affecting charging. Utility Model Content

[0008] Furthermore, the clamping mechanism includes an L-shaped fixing plate and a convex strip, the L-shaped fixing plate is fixed on both sides of the bottom of the boss, the convex strip is fixed on both sides of the protective cover and is movably connected to the L-shaped fixing plate, a circular hole is opened on one side of the convex strip, and a clamping assembly is provided between the L-shaped fixing plate and the circular hole.

[0009] Furthermore, the clamping assembly includes a fixed cover, which is fixed to one side of the L-shaped fixed plate. The interior of the fixed cover is slidably connected with a clamping column, which is movably connected to the circular hole. A limiting plate is fixed to the surface of the clamping column, and a first spring is sleeved on the surface of the clamping column.

[0010] Furthermore, a protrusion is fixed on the outer side of the clamping column, and chamfered structures are provided on both sides of the protrusion.

[0011] Furthermore, the sealing mechanism includes a groove, the groove is opened on the inner side of the protective cover, a sealing plate is hinged on the inner side of the protective cover, a second spring is hinged on the inner side of the groove, and the other end of the second spring is hinged on the inner side of the sealing plate.

[0012] Furthermore, a rubber sealing ring is bonded to the inner side of the protective cover, and the inner side of the rubber sealing ring is in contact with the sealing plate.

[0013] The utility model proposes a headset with a protective structure, which has the beneficial effects that: the utility model can seal the charging interface during use by means of the protective cover cooperating with the sealing plate, so as to prevent dust from entering the charging port; the sealing plate can rebound when the plug is pulled out by the second spring, so as to automatically prevent dust; the protective cover can be conveniently disassembled by means of the clamping column and the circular hole, so as to facilitate the maintenance of the charging interface.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A headset with a protective structure comprises at least two headset bodies 1, a connecting portion 2 is provided between the two headset bodies 1, a charging interface 3 is provided at the bottom of one side of the headset body 1, a boss 4 is provided on the outer side of the charging interface 3, a protective cover 5 is movably connected to the inner side of the boss 4, a clamping mechanism 6 is provided between the protective cover 5 and the boss 4, and a sealing mechanism 7 is provided on the inner side of the protective cover 5; the headset can seal the charging interface 3 during use through the protective cover 5 and the sealing plate 72 to prevent dust from entering the charging port, the sealing plate 72 can be rebounded by the second spring 73 when the plug is pulled out, and dust is automatically prevented, the protective cover 5 can be easily disassembled through the clamping column 82 and the round hole 63, and the charging interface 3 is convenient to repair.

[0021] In this embodiment, the clamping mechanism 6 includes an L-shaped fixing plate 61 and a convex strip 62. The L-shaped fixing plate 61 is fixed on both sides of the bottom of the boss 4. The convex strip 62 is fixed on both sides of the protective cover 5 and is movably connected to the L-shaped fixing plate 61. A circular hole 63 is opened on one side of the convex strip 62. A clamping assembly 8 is provided between the L-shaped fixing plate 61 and the circular hole 63. The L-shaped fixing plate 61 and the convex strip 62 can clamp the protective cover 5.

[0022] Furthermore, the clamping assembly 8 includes a fixed cover 81, which is fixed to one side of the L-shaped fixed plate 61. The interior of the fixed cover 81 is slidably connected with a clamping column 82, which is movably connected to the circular hole 63. A limiting plate 83 is fixed to the surface of the clamping column 82, and a first spring 84 is sleeved on the surface of the clamping column 82. The protective cover 5 can be easily disassembled through the clamping column 82 and the circular hole 63, so as to facilitate the maintenance of the charging interface 3.

[0023] Furthermore, a protrusion 9 is fixed to the outer side of the clamping column 82 , and chamfered structures are provided on both sides of the protrusion 9 . The protrusion 9 can fit the fingers, making it convenient to pull out the clamping column 82 .
