Description

Technical Field

[0001] The present invention relates to the technical field of earphone charging cases, and in particular to a Bluetooth earphone charging case. Background Art

[0002] Bluetooth earphones are earphones that are wirelessly connected to other devices through Bluetooth technology. Many existing Bluetooth earphones mostly need to be used in conjunction with a charging case. The charging case of Bluetooth earphones is a accessory for charging wireless earphones. It not only provides a charging function, but also has a built-in battery that can charge the earphones multiple times, extending the usage time of the earphones. For example, after some earphones are fully charged, the charging case can provide multiple charges, greatly increasing the total battery life of the earphones. The charging case can usually protect the earphones from external damage and prevent the earphones from being scratched or lost when not in use. Many Bluetooth earphones will automatically disconnect when placed in the charging case and automatically reconnect when taken out, providing a more convenient user experience.

[0003] However, there are still some problems with many existing Bluetooth earphones. When using Bluetooth earphones, it is usually necessary to take the earphones out of the charging case. Since the gap between the earphones and the charging case is small, it is rather troublesome to take out the earphones, especially when the hands are slippery, it will be even more difficult to pick up, which will reduce the usage effect of the earphone charging case. Moreover, most of the existing earphones are stored inside the charging case by magnetic attraction, but this method may not be stable enough. When subjected to external force, the earphones inside the charging case are likely to fall out, thus affecting the actual use. Therefore, it is necessary to solve the above problems. Summary of the Invention

[0004] Based on the technical problems existing in the background art, the present invention proposes a Bluetooth earphone charging case.

[0005] A Bluetooth headset charging case proposed by the present invention includes a charging case, a sealing cover and a lifting case. Two earphone bins are opened at the top of the charging case. Two contacts are fixedly connected inside each of the two earphone bins. Lifting grooves are vertically opened at the inner bottoms of the two earphone bins. There are two lifting cases, and the two lifting cases are vertically slidably connected inside the two lifting grooves. A sliding mechanism for sliding the two lifting cases is provided inside the charging case. Limiting mechanisms are provided inside each of the two lifting cases. The sealing cover is rotatably connected to the top of the charging case. A connecting groove is opened at one end of the top of the charging case. A first connecting block is fixedly connected to one end of the bottom of the sealing cover. The first connecting block is rotatably connected inside the connecting groove. A rotating mechanism for rotating the sealing cover is provided inside the charging case. Through the up-and-down sliding arrangement of the two lifting cases, it is convenient to slide the placed earphones up and down during use, so that it is more convenient to take and place the earphones, and it will also drive the sealing cover to open, thereby improving the convenience of the device. At the same time, when the earphones are placed inside the earphone bins, the surface of the earphones will be restricted, thereby improving the safety of the device.

[0006] Preferably, in a preferred embodiment, the sliding mechanism includes a lifting block. A communication groove is vertically opened inside the charging case. The communication groove is arranged between the two lifting grooves. A sliding rod is vertically fixedly connected inside the communication groove. The lifting block is vertically slidably connected inside the communication groove. The lifting block is slidably sleeved on the surface of the sliding rod. A first spring is sleeved on the surface of the sliding rod. The bottom end of the first spring is arranged on the top of the lifting block. The top end of the first spring is arranged on the inner top of the communication groove. First vertical grooves are vertically opened on the opposite sides inside the communication groove. The two first vertical grooves are respectively communicated with the inside of the two lifting grooves. Second connecting blocks are vertically slidably connected inside the two first vertical grooves. The two second connecting blocks are fixedly connected to the surface of the lifting block. One ends of the two second connecting blocks are respectively fixedly connected to the surfaces of the two lifting cases. A first sliding groove is vertically opened on one side of the surface of the charging case. A second sliding groove is vertically opened inside the first sliding groove. The second sliding groove is communicated with the inside of the communication groove. A sliding piece is vertically slidably connected inside the first sliding groove. Anti-slip patterns are arranged on the surface of the sliding piece. A first connecting rod is vertically slidably connected inside the second sliding groove. The first connecting rod is horizontally arranged. One end of the first connecting rod is fixedly connected to the surface of the sliding piece. The other end of the first connecting rod is fixedly connected to the surface of the lifting block, which is used to limit the up-and-down sliding of the lifting block and also drive the two lifting cases to slide up and down. At the same time, with the setting of the first spring, the two lifting cases are restricted at the inner bottoms of the two lifting grooves.

[0007] Furthermore, in a preferred embodiment, the limiting mechanism includes a limiting rod. A placement groove is provided at the top of the lifting box. Two limiting blocks are vertically and slidably connected to the arc surface of the lifting box. A limiting groove is vertically formed inside the lifting groove. Both of the two limiting blocks are vertically and slidably connected to the inside of the limiting groove. A slant block is fixedly connected to the bottom inside the limiting groove. The slant block is arranged between the two limiting blocks. The limiting rod is horizontally and slidably connected to the inside of the lifting box. One end of the limiting rod is slidably connected to the inside of the placement groove. The other end of the limiting rod is slidably connected between the two limiting blocks. A limiting ring is horizontally and slidably connected to the inside of the lifting box. The limiting ring is sleeved on the surface of the limiting rod. A second spring is sleeved on the surface of the limiting rod. One end of the second spring is arranged on the side of the limiting ring away from the two limiting blocks. The other end of the second spring is arranged inside the lifting box. One end of the limiting rod is slidably connected to the surface of the slant block. The limiting rod and the slant block cooperate to limit the horizontal sliding of the two limiting rods, so as to facilitate the insertion of the two limiting rods into the holes at the bottom of the earphone for cooperation, thereby restricting the placed earphone and further improving the stability of the placed earphone.

[0008] Preferably, in a preferred embodiment, the rotating mechanism includes a fixed shaft. An anti-slip groove is formed on one side of the surface of the sealing cover. There are two fixed shafts. The two fixed shafts are respectively fixedly connected to the symmetric two ends of the surface of the first connecting block. The two first connecting blocks are respectively rotatably sleeved on the two opposite ends inside the connecting groove. Two elastic pieces are fixedly connected to one side inside the connecting groove. Two first grooves, two convex grooves and two second grooves are respectively arranged on the surface of the first connecting block. Each first groove, each convex groove and each second groove are communicated with each other. The two elastic pieces cooperate with each first groove, each convex groove and each second groove respectively. The connecting groove is communicated with the inside of the communication groove. A fixed piece is fixedly connected to the surface of the first connecting block. The fixed piece is slidably connected to the inside of the communication groove. A second connecting rod is horizontally and fixedly connected to the side of the lifting block away from the first connecting rod. One end at the top of the second connecting rod is vertically and fixedly connected to a top rod. The top of the top rod is arranged at the bottom of the fixed piece. The top rod and the fixed piece cooperate to limit the rotation of the sealing cover, so that the sealing cover can be manually opened, or through the sliding of the lifting block, and then through the connection of the top rod and the fixed piece, the sealing cover can be rotated and opened.

[0009] In the present invention, during use, the sealing cover can be manually opened. At the same time, by sliding the sliding piece upward, the second connecting rod and the top rod can drive the fixed piece to slide, so that the first connecting block and the sealing cover rotate. At the same time, the two lifting boxes will also slide upward together with the placed earphone, making it more convenient to take out the earphone, thereby improving the use effect of the charging box.

[0010] When the earphone is placed inside the charging case, the limiting mechanism arranged inside the two lifting cases can limit the placed earphone, so that the earphone will not fall off after being placed, thereby improving the stability of placing the earphone.
