Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of an embodiment of a rotating shaft assembly according to the present application, and fig. 2 is an exploded schematic diagram of the rotating shaft assembly shown in fig. 1. It should be noted that the spindle assembly 10 of the present application may be used in wearable devices including VR glasses, AR glasses, smart watches, and the like. The rotary shaft assembly 10 includes a first bracket 100, a second bracket 200, a rotary member 300, an elastic member 400, and a pin 500.

Specifically, the second bracket 200 is provided with the slider 600, the slider 600 is connected with the rotating member 300 through the elastic member 400, the first bracket 100 is provided with the first rotating shaft hole 1101, the rotating member 300 is provided with the second rotating shaft hole 3201, and the pin 500 is inserted into the first rotating shaft hole 1101 and the second rotating shaft hole 3201, so that the first bracket 100 and the rotating member 300 can coaxially rotate, and further the first bracket 100 and the second bracket 200 can relatively rotate, and when the first bracket 100 and the second bracket 200 relatively rotate, the elastic deformation of the elastic member 400 changes. When the second bracket 200 is located at the first position, the elastic member 400 is in an initial elastic deformation state, so that a tensile force exists between the second bracket 200 and the rotating member 300, and further the first bracket 100 and the second bracket 200 are pressed together, when the first bracket 100 and the second bracket 200 relatively rotate, the elastic deformation of the elastic member 400 is increased, the tensile force between the first bracket 100 and the second bracket 200 is increased, the relative rotation of the first bracket 100 and the second bracket 200 generates a damping force, the probability that the rotation process of the first bracket 100 and the second bracket 200 is affected by external force to shake is reduced by the damping force, and a user can obtain damping hand feeling in the rotation process.

Optionally, the rotating shaft assembly 10 further includes an adjusting screw 700, where the adjusting screw 700 is used to adjust the position of the slider 600 on the second bracket 200, so as to adjust the initial elastic deformation of the elastic member 400.

Alternatively, the elastic member 400 may be made of rubber or alloy material with elastic deformation capability. The materials of the first bracket 100, the second bracket 200, the slider 600 and the rotator 300 may be metal or plastic. Further, the elastic member 400 may be a spring, which is positioned between the slider 600 and the rotation member 300 and is stretched, and when the first and second brackets 100 and 200 are relatively rotated, the elastic member 400 is further stretched, thereby generating a damping effect of the rotation.

Alternatively, referring to fig. 3 to 5 together, fig. 3 is a schematic structural view of a first bracket of the rotating shaft assembly shown in fig. 1, fig. 4 is a schematic structural view of a second bracket of the rotating shaft assembly shown in fig. 1, and fig. 5 is a schematic structural view of a rotating member of the rotating shaft assembly shown in fig. 1. The first bracket 100 includes a first body part 110 and a first connection part 120, the second bracket 200 includes a second body part 210 and a second connection part 220, and the slider 600 is mounted at an edge of the second connection part 220, and the first connection part 120 and the second connection part 220 may be connected with external components.

Further, referring to fig. 6 and 7, fig. 6 is a schematic structural view of a slider of the spindle assembly shown in fig. 1, and fig. 7 is a schematic sectional view of the spindle assembly shown in fig. 1. The second connecting portion 220 is provided with a guide rail 221 at an end far away from the second main body portion 210, the slider 600 is sleeved on the guide rail 221, and the elastic member 400 is connected with the slider 600, so that the elastic member 400 has a larger connection distance, and the elastic member 400 is in an elastic deformation state. In particular, the slider 600 may be moved away from or toward the second body portion 210 along the guide rail 221, and the adjustment screw 700 may be used to lock and fix the position of the slider 600 on the guide rail 221. Optionally, the slider 600 is provided with a threaded hole 610, and the threads on the adjustment screw 700 may mate with threads in the threaded hole 610, and by turning the adjustment screw 700, the position of the slider 600 on the rail 221 may be adjusted. When it is desired to increase the damping force of the relative rotation of the first and second brackets 100 and 200, the slider 600 may be locked at a position of the guide rail 221 away from the second body portion 210 by the adjusting screw 700 such that the distance from the slider 600 to the rotation member 300 increases, thereby increasing the initial elastic deformation of the elastic member 400 to increase the damping force of the rotation. When the damping force of the relative rotation of the first and second brackets 100 and 200 is excessively large, the slider 600 may be locked at a position of the guide rail 221 near the second body portion 210 by the adjusting screw 700 such that the initial distance of the slider 600 from the rotation member 300 is reduced, thereby reducing the initial elastic deformation of the elastic member 400 to reduce the damping force of the rotation.

The first body 110 has a boss 111, and the second body 210 has a top 211. The abutment 211 may contact the contact surface 112 of the first bracket 100, and when the first bracket 100 and the second bracket 200 relatively rotate, the abutment 211 is transformed from contact with the contact surface 112 to being supported by the boss 111, because the distance from the boss 111 to the first rotation shaft hole 1101 in the first body 110 is longer than the distance from the contact surface 112 to the first rotation shaft hole 1101, during rotation, the abutment 211 moves away from the second rotation shaft hole 3201 of the rotation member 300, and the slider 600 fixed to the second bracket 200 also moves away from the rotation member 300, because the slider 600 is connected to the rotation member 300 through the elastic member 400, and at this time, the elastic deformation amount of the elastic member 400 increases, and the tension between the slider 600 and the rotation member 300 increases, so that the relative rotation between the first bracket 100 and the second bracket 200 generates a damping force.

Alternatively, the rotating member 300 includes a first end 310 and a second end 320, the second shaft hole 3201 is located on the second end 320, and the first end 310 is connected to the elastic member 400.

In the process of rotating the second bracket 200, the rotating member 300 penetrating the through hole 2111 can be driven to rotate, and the abutting portion 211 is supported by the protruding portion 111 to move relatively to the rotating member 300, and is far away from the first rotating shaft hole 1101.

Optionally, the first support 100 is provided with a groove 1102, the second end 320 of the rotating member 300 is located in the groove 1102, a first rotating shaft hole 1101 is formed on a side wall of the groove 1102, the first rotating shaft hole 1101 can penetrate through a side wall of the groove 1102 to be communicated with the groove 1102, a second rotating shaft hole 3201 on the second end 320 is coaxially arranged with the first rotating shaft hole 1101, and the pin 500 is simultaneously inserted into the first rotating shaft hole 1101 and the second rotating shaft hole 3201, so that the first support 100 and the rotating member 300 can coaxially rotate, and further the first support 100 and the second support 200 can coaxially rotate.

Alternatively, the number of the grooves 1102 may be two, and the two ends of the first body 110 may be located at the same time, and accordingly, the number of the rotating members 300 may be two, the second ends 320 thereof are respectively disposed in the two grooves 1102, and the first ends 310 thereof are respectively connected to the two elastic members 400 through the two through holes 2111.
