Description

Technical Field

[0001] This utility model relates to the field of charging case technology, specifically a portable Bluetooth headset charging case. Background Technology

[0002] In the consumer electronics field, portable Bluetooth earphones have become mainstream audio devices due to their "wireless portability and flexible use." As the "battery replenishment station" and "storage carrier" for earphones, the portability and safety of the charging case directly determine the overall user experience. To balance "ease of use" and "structural simplicity," most portable Bluetooth earphone charging cases on the market adopt a "flip-top structure." This means that the main body of the charging case and the lid are connected by hinges, pivots, or flexible connecting parts. Users need to open the lid to take out and put in the earphones, and close the lid to charge and store them.

[0003] Based on the above, the inventors have discovered the following problems: the reliability of the flip-top closure relies on a "weak fixing structure," which is easily triggered by vibration and pressure. To reduce the user's resistance to opening and closing, most flip-top charging cases adopt a "magnetic closure" or "shallow snap-fit" design. The magnetic closure relies on the small magnet between the case cover and the main body for attraction. If the charging case comes into contact with metal objects such as keys or coins while being carried, the magnetic attraction will be interfered with, causing the flip-top to loosen. The shallow snap-fit ​​design uses plastic protrusions on the edge of the case cover to slightly engage with the grooves in the main body. After long-term use, the protrusions are prone to wear, which greatly reduces the closure stability. In daily carrying scenarios, the charging case will vibrate and collide with the human body or objects. When the external force exceeds the closing fixing force, the flip-top will automatically pop open, causing the internal earphones to fall out. This may not only damage the earphones but also affect their use due to the loss of the earphones.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a portable Bluetooth headset charging case in order to achieve a more practical value. Utility Model Content
