Description

Technical Field

[0001] The present invention relates to the technical field of a TWS Bluetooth headset charging box, and in particular to a TWS Bluetooth headset charging box with a double-shaft cover. Background Art

[0002] At present, TWS Bluetooth headsets are popular among users because they are not bound by wires and are easy to store. In order to increase the battery life of TWS Bluetooth headsets, TWS Bluetooth headsets are usually equipped with a charging box. When users are not using TWS Bluetooth headsets, they can be stored in the charging box.

[0003] In the prior art, see Chinese patent document CN113972719A, the TWS Bluetooth headset charging box is usually composed of a box body and a cover body, and the TWS Bluetooth headset is placed in the box body, and the box body is provided with a battery and a PCB board for charging the headset. This type of charging box is relatively traditional and cannot bring consumers a relatively novel box opening experience. Moreover, when the cover body is rotated open from the top of the box body, it can only rotate less than 100 degrees, which is inconvenient to take out the TWS Bluetooth headset from the box body or put the TWS Bluetooth headset into the box body.

[0004] Chinese patent application document CN110881154A discloses an earphone charging box, including a first box body and a second box body, wherein the first box body is provided with a first receiving groove for placing the first earphone, and the second box body is provided with a second receiving groove for placing the second earphone; the first box body is rotatably connected to the second box body; when the first receiving groove and the second receiving groove are close to each other, the charging box is closed; when the first receiving groove and the second receiving groove are away from each other, the charging box is opened. Compared with the traditional charging box form of a box body and a cover body, this patent provides consumers with a double-opening box form with a better user experience. However, the patent CN110881154A adopts a single-axis cover opening method, which has the technical defect that the sleeves of the first box body and the second box body mounted outside the shaft need to protrude outward in an arc shape (see the attachment of the patent). Figure 2-5 ), therefore, when the first box body and the second box body are covered, a long cylindrical protrusion will be formed at the position of the rotating shaft. This long cylindrical protrusion will lift up the earphone charging box, making it impossible for the earphone charging box to be placed flat, affecting the normal use of the earphone charging box.

[0005] If the cover opening hinge structure between the first box body and the second box body of patent CN110881154A is designed to be the flip-open cover hinge structure shown in patent CN113972719A, although a long cylindrical protrusion will not be formed at the position of the hinge after the first box body and the second box body are closed, when the first box body and the second box body are rotated to open, they can only rotate less than 100 degrees, which is more inconvenient to take out the TWS Bluetooth headset from the box body or put the TWS Bluetooth headset into the box body. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a TWS Bluetooth headset charging box with a double-axis opening cover based on the above-mentioned deficiencies in the prior art.

A Bluetooth transmitter is a Bluetooth device adapted to smart devices such as smart phones, tablet computers, laptops, desktop computers, smart screens, etc. The Bluetooth transmitter usually has a USB Type A interface or a USB Type C interface or an Apple mobile phone Lightning Dock interface. After the Bluetooth transmitter is plugged into the smart device, the smart device can be connected to the TWS Bluetooth headset through the Bluetooth transmitter. Since the Bluetooth modules of smart devices such as mobile phones and tablet computers have high delay, more distortion and insufficient transmission speed after being connected to the TWS Bluetooth headset by Bluetooth, when the smart device is plugged into the Bluetooth transmitter, the signal transmission between the smart device and the TWS Bluetooth headset can achieve low delay, low distortion and fast transmission speed. Therefore, some headset users (especially game players and music lovers) usually plug in Bluetooth transmitters on smart devices while using TWS Bluetooth headsets. The present invention provides a third accommodating cavity 205 for accommodating the Bluetooth transmitter within the second box body 200, so that the TWS Bluetooth headset charging box can accommodate the Bluetooth transmitter and the TWS Bluetooth headset at the same time, which is very convenient to use.
