[0042] Refer to Figure 1 and Figure 2, an embodiment of the present application provides a rotating shaft structure, which includes:
[0043] A first bracket 1, on which a first connecting arm 11 and a second connecting arm 12 are provided, and an assembly gap is formed between the first connecting arm 11 and the second connecting arm 12;
[0044] A holding member 2, which is arranged on the first connecting arm 11;
[0045] A second bracket 3 and a connecting rod 4, the second bracket 3 is arranged in the assembly gap, a through groove 31 is arranged in the second bracket 3, the connecting rod 4 is connected between the first connecting arm 11 and the second connecting arm 12 and penetrates through the through groove 31, and the holding member 2 has a protrusion 21 extending into the through groove 31;
[0046] An elastic component 5, which is arranged in the through groove 31 and abuts against the protrusion 21 to form a damping during the rotation of the second bracket 3 relative to the first bracket 1.
[0047] In this embodiment, the first bracket 1 serves as a fixed bracket in the rotating shaft structure; the second bracket 3 serves as a rotating bracket in the rotating shaft structure; the connecting rod 4 is connected between the first connecting arm 11 and the second connecting arm 12 and penetrates through the through groove 31, that is, at least part of the structure of the second bracket 3 is connected to the assembly gap, and the first bracket 1 and the second bracket 3 are connected through the connecting rod 4.
[0048] In one embodiment, both ends of the connecting rod 4 are fixedly connected to the first connecting arm 11 and the second connecting arm 12, and the second bracket 3 can rotate relative to the connecting rod 4 to avoid the separation of the first bracket 1 and the second bracket 3 on the basis of realizing the rotation of the second bracket 3 relative to the first bracket 1.
[0049] The elastic component 5 is arranged in the through groove 31 and abuts against the protrusion 21. The abutment of the protrusion 21 against the elastic component 5 causes the elastic component 5 to be compressed, and the compressed elastic component 5 can generate a rotational damping between the second bracket 3 and the first bracket 1. In one embodiment, the first bracket 1 is adapted to be fixed to the middle frame of the smart glasses, and the second bracket 3 is adapted to be fixed to the temple of the smart glasses, that is, a damping force is generated during the folding and unfolding of the temple relative to the frame, so that the smart glasses have a suitable clamping force on the wearer's head during wearing, preventing the smart glasses from falling off when the wearer is moving.
[0050] In one embodiment, referring to Figure 2 , the first connecting arm 11 of the first bracket 1 has a mounting groove, the holding member 2 is assembled into the mounting groove on the first connecting arm 11, and both ends of the connecting rod 4 of the pin shaft structure are fixedly installed in the connecting holes of the holding member 2 and the connecting holes of the second connecting arm 12.
[0051] The shaft structure provided by the embodiment of the present application includes a first bracket 1, on which a first connecting arm 11 and a second connecting arm 12 are provided, and an assembly gap is formed between the first connecting arm 11 and the second connecting arm 12; a holding member 2, which is arranged on the first connecting arm 11; a second bracket 3 and a connecting rod 4, the second bracket 3 is arranged in the assembly gap, a through groove 31 is arranged in the second bracket 3, the connecting rod 4 is connected between the first connecting arm 11 and the second connecting arm 12 and penetrates through the through groove 31, and the holding member 2 has a protrusion 21 extending into the through groove 31; an elastic component 5, which is arranged in the through groove 31 and abuts against the protrusion 21 to form damping during the rotation of the second bracket 3 relative to the first bracket 1; by arranging the elastic component and at least part of the protrusion in the through groove, the second bracket forms protection for the cooperation of the elastic component and the protrusion, ensuring the stability of the operation of the shaft structure.
[0052] In one embodiment, refer to Figure 2 and Figure 3 , the elastic component 5 includes a movable block 51 and a spring 52, the movable block 51 is sleeved on the connecting rod 4 and can move in the through groove 31, the spring 52 is arranged on the side of the movable block 51 away from the protrusion 21, and the protrusion 21 abuts against the movable block 51 to keep the spring 52 in a compressed state;
[0053] Wherein, both the movable block 51 and the spring 52 are hidden in the through groove 31.
[0054] In this embodiment, during the rotation of the second bracket 3 relative to the first bracket 1, the protrusion 21 remains in contact with the movable block 51 to apply a holding force to the movable block 51 towards the spring 52 through the protrusion 21; both ends of the spring 52 abut against the movable block 51 and the bottom wall of the through groove 31 respectively, and the movable block 51 can continuously compress the spring 52 under the holding action of the protrusion 21, and the compressed spring 52 can generate rotational damping between the second bracket 3 and the first bracket 1, and the second bracket 3 forms protection for the movable block 51 and the spring 52 through the through groove 31, and the second bracket 3 can rotate stably relative to the first bracket 1, ensuring the smoothness during the folding and unfolding of the second bracket 3 relative to the first bracket 1.
[0055] In one embodiment, refer to Figure 4 and Figure 5 , the inner wall of the through groove 31 forms a limiting surface, the outer periphery of the movable block 51 forms a mating surface, and the mating surface is in limiting cooperation with the limiting surface to limit the rotation of the movable block 51 in the through groove 31.
[0056] In this embodiment, when the movable block 51 is arranged in the through groove 31, the outer periphery of the movable block 51 can be in close contact with the inner wall of the through groove 31 to ensure the synchronism of the rotation of the second bracket 3 and the movable block 51; or a movable gap is left between the outer periphery of the movable block 51 and the inner wall of the through groove 31, so as to facilitate the movable block 51 to slide along the connecting rod 4 to compress the spring 52 on the basis of the synchronous rotation of the second bracket 3 and the movable block 51.
[0057] The mating surface and the limiting surface are in limiting cooperation. For example, when the movable block 51 has a tendency to rotate in the through groove 31, the limiting surface will be at least partially in contact with the mating surface to limit the rotation of the movable block 51 in the through groove 31, which not only ensures the synchronous rotation of the second bracket 3 and the movable block 51, but also facilitates the movable block 51 to slide along the connecting rod 4.
[0058] In one embodiment, the limiting surface is a square or oval limiting surface, and the mating surface is a square or oval mating surface.
[0059] In this embodiment, when the limiting surface on the inner wall of the through groove 31 is a square limiting surface, the mating surface on the outer periphery of the movable block 51 is a square mating surface that mates with the square limiting surface. Specifically, the square mating surface can be in contact with the square limiting surface, or a movable gap is left between the square mating surface and the square limiting surface, but the rotation of the movable block 51 in the through groove 31 is restricted.
[0060] Alternatively, when the limiting surface on the inner wall of the through groove 31 is an oval limiting surface, the mating surface on the outer periphery of the movable block 51 is an oval mating surface that mates with the oval limiting surface. Specifically, the oval mating surface can be in contact with the oval limiting surface, or a movable gap is left between the oval mating surface and the oval limiting surface, but the rotation of the movable block 51 in the through groove 31 is restricted to ensure the synchronous rotation of the second bracket 3 and the movable block 51.
[0061] In one embodiment, the elastic component 5 is an elastic plastic part or an elastic rubber part.
[0062] In this embodiment, the elastic component 5 is an elastic part such as an elastic plastic part or an elastic rubber part filled in the through groove 31, and the protrusion 21 abuts against the elastic part and can compress the elastic part, so that the compressed elastic part can generate an elastic force that reversely presses against the abutting part 2, so as to generate a continuous rotational damping between the second bracket 3 and the first bracket 1.
[0063] It should be noted that when the elastic component 5 is an elastic part such as an elastic plastic part or an elastic rubber part, the elastic part can rotate synchronously with the second bracket 3, or the elastic part and the connecting rod 4 are relatively fixed, and the second bracket 3 rotates relative to the elastic part. In both cases, damping can be provided through the deformation of the elastic part.
[0064] In one embodiment, see Figure 1 andFigure 2 , a limiting groove 13 is provided on the first connecting arm 11, and a limiting slider 32 is provided on the second bracket 3. The limiting slider 32 is slidably engaged with the limiting groove 13;
[0065] The limiting groove 13 has a first end face and a second end face facing away from each other. When the rotating shaft structure is in the retracted state, the limiting slider 32 abuts against the first end face. When the rotating shaft structure is in the deployed state, the limiting slider 32 abuts against the second end face.
[0066] In this embodiment, when the rotating shaft structure is in the retracted state, for example, when the temple connected to the second bracket 3 is folded at 0° relative to the frame connected to the first bracket 1, the temple drives the second bracket 3 to be flush with the first bracket 1. At this time, the limiting slider 32 abuts against the first end face to limit the excessive folding of the temple, avoiding the collision and wear of the temple against the frame.
[0067] When the rotating shaft structure is in the deployed state, for example, when the temple is folded at 90 - 100° relative to the frame, the temple drives the second bracket 3 to be perpendicular to the first bracket 1 or in an unfolded state with an obtuse angle. At this time, the limiting slider 32 abuts against the second end face, avoiding the excessive unfolding and deformation of the temple relative to the frame, and ensuring the integrity of the structure of the smart glasses.
[0068] In one embodiment, referring to Figure 3 , at least one groove 53 is formed on one side of the movable block 51 facing the protrusion 21. The surface of the groove 53 forms a corrugated surface, and the protrusion 21 abuts against the corrugated surface.
[0069] In this embodiment, the surface of the groove 53 has a corrugated surface with an uneven structure. During the rotation of the movable block 51 following the second bracket 3, the protrusion 21 alternately abuts against the concave and convex parts of the corrugated surface, so as to generate a top force with a changing magnitude on the movable block 51 through the protrusion 21. This top force is directed towards the spring 52, and further generates a changing rotational damping between the second bracket 3 and the first bracket 1 by compressing the spring 52.
[0070] In one embodiment, two relatively arranged grooves 53 are formed on one side of the movable block 51 facing the protrusion 21. The top member 2 has two protrusions 21 extending into the through groove 31, and the two protrusions 21 are respectively in corresponding cooperation with the two grooves 53 to ensure the smooth rotation of the movable block 51 following the second bracket 3.
[0071] In one embodiment, referring to Figure 4 , the corrugated surface has a first concave portion 531 and a second concave portion 532;
[0072] When the rotating shaft structure is in the retracted state, the protrusion 21 abuts against the first recess 531, and the spring 52 has a first compression value. When the rotating shaft structure is in the deployed state, the protrusion 21 abuts against the second recess 532, and the spring 52 has a second compression value. The first compression value and the second compression value are equal.
[0073] In this embodiment, when the rotating shaft structure is in the retracted state, that is, the temple connected to the second bracket 3 is folded relative to the frame connected to the first bracket 1 at a folding angle of 0°, and when the rotating shaft structure is in the deployed state, that is, the temple is folded relative to the frame at a wearing angle of 90 - 100°. And the temple being folded relative to the frame at 0° or at 90 - 100° are the two most commonly used states of the smart glasses. The first compression value and the second compression value are equal in these two states, which can ensure the stability of the rotational damping of the temple in the common states of the smart glasses.
[0074] In one embodiment, referring to Figure 4 , the corrugated surface has a first protrusion 533, and the first protrusion 533 is located between the first recess 531 and the second recess 532;
[0075] When the rotating shaft structure is switched from the retracted state to the deployed state, the protrusion 21 abuts against the first protrusion 533, and the spring 52 has a third compression value;
[0076] Among them, the third compression value is greater than the first compression value and the second compression value.
[0077] In this embodiment, during the process of the temple connected to the first bracket 1 unfolding from the folded state of 0° relative to the frame connected to the second bracket 3 to the wearing state of 90 - 100°, the movable block 51 rotates together with the second bracket 3. Due to the abutting effect of the holding member 2 on the movable block 51 in the axial direction, the movable block 51 will compress the spring 52 along the direction of the connecting rod 4 during rotation, and the degree of compression of the spring decreases first and then increases, and then decreases and increases again, so as to adjust the damping force during the rotation of the second bracket 3 relative to the first bracket 1.
[0078] And during the process of the temple closing from 90 - 100° to 0° relative to the frame, the degree of compression of the spring decreases first and then increases, and then decreases and increases again, so as to provide a variable damping force through the friction between the movable block 51 and the holding member 2.
[0079] In one embodiment, an inclined surface is formed on the side of the second recess 532 away from the first recess 531, so that after the temple is unfolded relative to the frame to 90°, since the movable block 51 can still rotate relative to the holding member 2 by 0 - 10°, the spring 52 continuously provides a damping force during the rotation process, and the clamping effect of the smart glasses on the wearer's head can be realized.
[0080] The embodiment of the present application also provides a pair of smart glasses, which includes the rotating shaft structure described above.
[0081] In this embodiment, the rotating shaft structure of the smart glasses includes a first bracket 1, on which a first connecting arm 11 and a second connecting arm 12 are arranged, and an assembly gap is formed between the first connecting arm 11 and the second connecting arm 12; a holding member 2 is arranged on the first connecting arm 11; a second bracket 3 and a connecting rod 4, a through groove 31 is arranged in the second bracket 3, the connecting rod 4 is connected between the first connecting arm 11 and the second connecting arm 12 and penetrates through the through groove 31, and the holding member 2 has a protrusion 21 extending into the through groove 31; an elastic component 5 is arranged in the through groove 31 and abuts against the protrusion 21 to form damping during the rotation of the second bracket 3 relative to the first bracket 1; by arranging the elastic component and at least part of the protrusion in the through groove, the cooperation between the second bracket and the elastic component and the protrusion forms protection, ensuring the stability of the operation of the rotating shaft structure, enabling the smart glasses to have a clamping force during wearing, and ensuring the stability of wearing the smart glasses.
[0082] In one embodiment, the smart glasses include a frame and temple arms;
[0083] The first bracket 1 is fixed to the frame, and the second bracket 3 is fixed to the temple arms.
[0084] In this embodiment, the first bracket 1 is fixedly connected to the frame of the smart glasses with screws or glue, and the second bracket 3 is fixedly connected to the temple arms of the smart glasses with screws or glue to ensure the integral structure of the first bracket 1 and the frame, and the integral structure of the second bracket 3 and the temple arms.
[0085] In another embodiment, the first bracket 1 can be fixed to the display unit of the head-mounted device, and the second bracket 3 can be fixed to the headband unit of the head-mounted device to achieve flexible rotation of the display unit relative to the headband unit.
