Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to a rotating shaft mechanism. Background Art

[0002] TWS earphones (True Wireless Stereo Earbuds) are wireless earphones. Compared with traditional wired earphones, the biggest difference is that there is no connecting wire. The two earphones are completely independent and connected to the audio source device via Bluetooth technology. This design allows users to move more freely without being bound by cables. TWS earphones usually consist of two independent earphones, each of which contains components such as a Bluetooth chip, battery, speaker and microphone. The two earphones can work at the same time to achieve a stereo effect, or they can be used separately, such as answering calls in single-ear mode or listening to music with only one earphone. The advantages of TWS earphones include strong portability, ease of use, and stylish appearance. At the same time, with the development of technology, many TWS earphones now also have functions such as intelligent noise reduction, touch operation, waterproof and sweat-proof, etc., to bring users a better audio experience. Since the advent of TWS earphones, they have been a good tool for mobile business people to improve efficiency. Existing TWS earphones need to be stored in an earphone box when not in use, which not only protects them but also charges the Bluetooth earphones.

[0003] Generally speaking, a TWS earphone box includes a TWS earphone cover and a TWS earphone compartment. However, the current earphone box only relies on a hinge to control the opening and closing of the earphone cover and the earphone box.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0029] Reference Figures 1 to 8 The utility model discloses a rotating shaft structure. Specifically, the structure includes a fixed part 10, a movable part 20, a rotating shaft 30 and a torsion spring 40. The fixed part 10 is connected to the movable part 20 through the rotating shaft 30. A torsion spring 40 is also arranged between the fixed part 10 and the movable part 20. One end of the torsion spring 40 is connected to the fixed part 10, and the other end of the torsion spring 40 is connected to the movable part 20. Under the action of the torsion spring 40, the movable part 20 is rotated by the elastic force provided by the torsion spring 40.

[0030] Specifically, the fixing part 10 includes a fixing base 101 and a connecting part 102; positioning holes 1011 are provided at both ends of the fixing base 101, and screws, pins, etc. are provided in the positioning holes 1011 so that the fixing part 10 can be fixed in the earphone compartment.

[0031] Two connecting parts 102 are provided, and the two connecting parts 102 are symmetrically arranged at both ends of the fixed base 101. The connecting part 102 includes a first protrusion 1021 and a second protrusion 1022, and the second protrusion 1022 is connected to the outer side wall of the first protrusion 1021, and the first protrusion 1021 and the second protrusion 1022 are integrally formed. The first protrusion 1021 extends along the height direction of the fixed base 101 to form a protrusion in the vertical direction, and the second protrusion 1022 extends along the width direction of the first protrusion 1021 to form a protrusion in the horizontal direction. Similarly, the structure of the other connecting part 102 is the same as that of the first connecting part 102. The structure of the other connecting part 102 also includes a first protrusion 1021 and a second protrusion 1022. The second protrusion 1022 is connected to the outer wall of the first protrusion 1021. The first protrusion 1021 extends along the height direction of the fixed base 101 to form a protrusion in the vertical direction. The second protrusion 1022 extends along the width direction of the first protrusion 1021 to form a protrusion in the horizontal direction. The second protrusion 1021 of the connecting part 102 is provided with a through hole 1023 along the length direction of the fixed base 101. The through hole 1023 is used to install the rotating shaft 30.

[0032] The movable part 20 is block-shaped, and a through hole 203 is also provided at the bottom of the movable part 20. The through hole 203 is provided along the length direction of the movable part 20. When the movable part 20 is connected to the fixed part 10, the through hole provided on the second protrusion 1021 of the connecting part 102 and the through hole 203 provided at the bottom of the movable part 20 are located on the same straight line. At this time, the rotating shaft 30 can be installed and inserted into the through hole of any one of the second protrusions 1021, and then pass through the through hole of the movable part 20, and finally pass through the through hole of the other second protrusion 1021, so as to realize the connection between the fixed part 10 and the movable part 20.

[0033] The spacing between the two second protrusions 1021 of the connecting part 102 is slightly larger than the width of the movable part 20. When the fixed part 10 is connected to the movable part 20, the movable part 20 can be placed in the spacing between the connecting parts 102. The movable part 20 is also provided with a plurality of fixing holes 201, which are used to connect with the Bluetooth headset cover. A plurality of limiting protrusions can be provided on the Bluetooth headset cover, and the limiting protrusions are passed through the fixing holes 201 of the movable part 201 to connect the Bluetooth headset cover with the movable part.

[0034] Because the first protrusion 1021 extends along the height direction of the fixed base 101 to form a protrusion in the vertical direction, and the second protrusion 1022 extends along the width direction of the first protrusion 1021 to form a protrusion in the horizontal direction, and the second protrusion 1022 is connected to the outer wall of the first protrusion 1021, there is a gap between the first protrusion 1021 and the movable part 20. When the movable part 20 rotates, due to the existence of the gap, the first protrusion 1021 will not restrict the rotation of the movable part 20.

[0035] A torsion spring fixing hole 202 is also provided at the bottom of the movable part 20, one end of the torsion spring 40 passes through the torsion spring fixing hole 202 and is connected to the movable part, the other end of the torsion spring 40 is connected to the fixed base 101, and the connection position between the other end of the torsion spring 40 and the fixed base 101 is between the two connecting parts 102. Under the action of the torsion spring 40, the movable part 20 is rotated under the action of the rotating shaft 30 through the elastic force provided by the torsion spring 40. After the fixed part 10, the movable part 20, the rotating shaft 30 and the torsion spring 40 are connected, the movable part 20 is connected to the earphone cover, and the fixed part 10 is connected to the earphone compartment. Under the action of the rotating shaft and the torsion spring 40, the earphone cover is rotated through the rotating shaft structure, thereby realizing the opening and closing of the earphone box.

[0036] In this solution, the elastic force provided by the torsion spring 40 allows the movable part 20 to rotate under the action of the rotating shaft 30, so that the earphone cover can be opened and closed relative to the earphone compartment. The provided torque value is 1±0.3kgf.mm, which can make the earphone cover and the earphone compartment reach 93° in the relatively open state. The overall rotating shaft structure has no sharp edges, corners and burrs, does not affect safe use, meets the test requirements of opening and closing force and life, and the rotation process is smooth.

[0037] The utility model also provides an earphone box, which includes an earphone cover and an earphone compartment. The earphone cover is connected to the movable part 20, and the earphone compartment is connected to the fixed part 10. Under the action of the rotating shaft structure, the earphone box can be opened and closed.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
