[0019] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0020] The present embodiment proposes a rotating shaft connecting rod structure of a headset and a display optical machine, referring to Figure 1 and Figure 2 , comprising a headband 1 for wearing, earphones 2 corresponding to human ears, and a display light machine 3 corresponding to human eyes, wherein the earphones 2 and the display light machine 3 are mounted on the headband 1, and the display light machine 3 is connected to the headband 1 through at least one set of rotating shaft connecting rod mechanisms;

[0021] The pivot-link mechanism comprises a first link 41, a second link 42, a third link 43 and a fourth link 44 connected in sequence, the first link 41 is arranged in a direction perpendicular to the display light machine 3, the second link 42, the third link 43 and the fourth link 44 are arranged in a direction parallel to the display light machine 3; the display light machine 3 is connected to the first link 41 through a first pivot 51, the first link 41 is connected to the second link 42 through a second pivot 52, the second link 42 is connected to the third link 43 through a third pivot 53, the third link 43 is connected to the fourth link 44 through a fourth pivot 54, and the fourth link 44 is fixedly connected to the headband 1; the first pivot 51 and the second pivot 52 are rotatably mounted around the Z-axis direction, the third pivot 53 is swingably mounted along the X-axis direction, and the fourth pivot 54 is rotatably mounted around the X-axis direction.

[0022] It should be noted that the present embodiment improves the connection method between the existing headset 2 and the display light machine 3, and adopts at least one set of pivot-connecting rod structures. Through the multi-degree-of-freedom rotation and angle adjustment between the pivot-connecting rod mechanisms, it can ensure that during use, the display light machine 3 always remains directly in front of the human eye, avoiding the user experience being affected by position offset. When not in use, the display light machine 3 can be flipped over a certain angle without affecting the user's experience, and the display light machine 3 can also be rotated 180°, thereby reducing the volume of the overall product for easy storage.

[0023] Furthermore, the rotating shaft connecting rod mechanism is provided in two groups, and the two groups of the rotating shaft connecting rod mechanism are symmetrically installed at two ends of the display light machine 3 to ensure the stability of the installation of the display light machine 3.

[0024] Specifically, when the user wears the earphones 2, the two earphones 2 need to be pulled outward to the left and right sides. At this time, the third connecting rod 43 and the second connecting rod 42 rotate relative to each other (the third rotating shaft 53 will swing upward along the guide slot 431), the second connecting rod 42 and the first connecting rod 41 rotate relative to each other around the second rotating shaft 52, and the first connecting rod 41 and the display optical machine 3 rotate relative to each other around the first rotating shaft 51. By changing the degrees of freedom of the three positions, the influence of the force on the display optical machine 3 when the earphones 2 are opened is eliminated, thereby ensuring that the display optical machine 3 is always in a horizontal position. In this embodiment, a torsion spring 8 is sleeved on the outside of the first rotating shaft 51 or the second rotating shaft 52. During wearing, the relative rotation between the connecting rods will give the torsion spring 8 a certain external force to cause it to deform. When the earphones 2 are worn, they are pulled apart by a certain angle compared to before wearing. At this time, the connecting rods will tend to return to the initial position under the action of the elastic restoring force of the torsion spring 8 itself, thereby ensuring that the earphones 2 and the display optical machine 3 can be worn stably and prevented from loosening.

[0025] Further, refer to Figure 3 The third rotating shaft 53 is configured in pairs, and the two third rotating shafts 53 are symmetrically arranged on both sides of the second connecting rod 42 along the X-axis direction. Both sides of the third connecting rod 43 are respectively provided with guide grooves 431 along the Z-axis direction for swinging and guiding the third rotating shaft 53, thereby ensuring the stability of the connection between the second connecting rod 42 and the third connecting rod 43, and at the same time, ensuring the stability of the rotation process.

[0026] Furthermore, the fourth connecting rod 44 is provided with a slot 441 corresponding to the third connecting rod 43, the fourth rotating shaft 54 ​​is inserted into the slot 441, the third connecting rod 43 is provided with a through hole 432 for the fourth rotating shaft 54 ​​to pass through, and the bottom of the slot 441 is provided with a limiting support platform 442 for supporting the third connecting rod 43; a toothed disk 433 is installed on the side of the third connecting rod 43, and a plurality of bosses 443 for engaging with the serrations of the toothed disk 433 are arranged on the inner side of the slot. The limiting support platform 442 at the bottom of the slot 441 can effectively limit the third connecting rod 43 so that its lowest position is in the horizontal direction (at this time, the display light machine 3 is just in front of the human eye and can be used normally). When it is not needed, the third connecting rod 43 can be driven to rotate 90° in the slot 441, so that the display light machine 3 is rotated to the top of the headset 2 for easy storage. In this embodiment, the fixed angle adjustment of the third connecting rod 43 can be achieved by setting the clamping structure of the toothed disk 433 and the boss 443. Specifically, the angle between two adjacent serrations on the toothed disk 433 described in this embodiment is set to 22.5°, that is, the third connecting rod 43 can be rotated and adjusted at intervals of 22.5° to meet the use requirements of different angles.

[0027] Furthermore, the display light machine 3 is also equipped with a sensor, a camera and a flash light to expand the function of the display light machine 3 and enhance the user experience.

[0028] Furthermore, the display optical machine 3 and the earphone 2 are connected via an FPC soft flat cable or a high-frequency cable. A wiring groove for the FPC soft flat cable or the high-frequency cable to pass through is opened inside the hinge connecting rod mechanism. In this embodiment, an FPC soft flat cable 9 is used for wiring to ensure the overall beauty of the product. The internal space is used for wiring without exposing the wires.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
