[0042] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0043] like Figure 1 and Figure 2 As shown, a head-mounted assembly 100 of an embodiment includes a head-mounted bracket 110, an ear shell bracket 120, a first elastic damping member 130 and a machine screw 140. The head-mounted bracket 110 is provided with a threading connection portion 110a. Figure 3 to Figure 4 The threading connection portion 110a is provided with a screw hole 102, a rotation limiting groove 104 and a damping positioning groove 106, and the rotation limiting groove 104 is connected to the screw hole 102 and the damping positioning groove 106 respectively. Figures 6 to 9 As shown, the inner peripheral wall of the rotation limiting groove 104 is respectively provided with a first limiting boss 1042 and a second limiting boss 1044. The ear shell bracket 120 is provided with a first rotating shaft 122. Figure 4 The first rotating shaft 122 is provided with a first through hole 1222. Fig.10As shown, a first limit block 1221 and a second limit block 1223 are convexly provided on the outer peripheral wall of the first rotating shaft 122, the first rotating shaft 122 is located in the rotation limit groove 104 and is rotationally connected to the threading connection part 110a, the first limit block 1221 is used to abut against the first limit boss 1042 when the first rotating shaft 122 rotates to a first predetermined angle along the first direction relative to the head-mounted bracket 110, so that the first limit boss 1042 plays a limiting role on the first limit block 1221 when the first rotating shaft 122 rotates along the first direction.

[0044] Further, the second limiting block 1223 is used to abut against the second limiting boss 1044 when the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head mounted bracket 110, so that the second limiting boss 1044 plays a limiting role in the second limiting block 1223 rotating along the second direction with the first rotating shaft. The first direction is opposite to the second direction. In this embodiment, the first direction is the clockwise direction, and the second direction is the counterclockwise direction. Due to the limiting effect of the first limiting boss 1042 and the second limiting boss 1044, the first rotating shaft 122 is prevented from rotating excessively relative to the head mounted bracket 110, so that the first rotating shaft 122 can be reliably rotated within a preset rotation angle range relative to the head mounted bracket 110.

[0045] In one embodiment, the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and abuts against the threading connection portion 110a. Figure 4 As shown, the machine screw 140 is inserted into the first through hole 1222 and is rotatably connected to the ear shell bracket 120. Figure 5 As shown, the outer peripheral wall of the machine screw 140 is formed with an external thread 141, and the external thread 141 is located in the threaded hole 102 and is threaded with the threading connection part 110a, so that the machine screw 140 connects the ear shell bracket 120 to the head-mounted bracket 110, and the ear shell bracket 120 is rotatably connected with the head-mounted bracket 110. In addition, the first rotating shaft 122 is sleeved with a first elastic damping member 130, and the first elastic damping member 130 is located in the damping positioning groove 106 and is connected to the threading connection part 110a, so that there is a damping effect during the relative rotation of the ear shell bracket 120 and the head-mounted bracket 110. The machine screw 140 is formed with a threading hole for threading the head-mounted wire 20, so that the head-mounted wire 20 can be better accommodated and installed at the connection position between the head-mounted bracket 110 and the ear shell bracket 120.

[0046] In the head-mounted assembly 100, the threading connection portion 110a is provided with a screw hole 102, a rotation limit groove 104 and a damping positioning groove 106, the rotation limit groove 104 is respectively connected with the screw hole 102 and the damping positioning groove 106, the first rotating shaft 122 is provided with a first through hole 1222, the machine screw 140 is passed through the first through hole 1222 and is rotatably connected to the ear shell bracket 120, and the outer peripheral wall of the machine screw 140 is formed with an external thread, which is located in the screw hole 102 and connected to the threading connection portion The first rotating shaft 122 is screwed to the head bracket 110a, so that the machine screw 140 fixes the first rotating shaft 122 to the head bracket 110, and the ear shell bracket 120 is rotatably connected to the machine screw 140, so that the ear shell bracket 120 and the head bracket 110 are relatively rotatably connected. In addition, because the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and abuts against the threading connection portion 110a, there is rotation damping between the ear shell bracket 120 and the head bracket 110. In this way, there is rotation damping between the two brackets, which improves the user experience of the headset, does not need to add hinge components, greatly reduces the assembly process of the headset, and reduces the cost of the headset; since the inner peripheral wall of the rotation limiting groove 104 is respectively provided with a first limiting boss 1042 and a second limiting boss 1044, and the outer peripheral wall of the first rotating shaft 122 is respectively provided with a first limiting block 1221 and a second limiting block 1223, when the first rotating shaft 122 is rotated to a first predetermined angle relative to the head-mounted bracket 110 along the first direction, When the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head mounted bracket 110, the first limiting block 1221 abuts against the first limiting boss 1042 to prevent the first rotating shaft 122 from excessively rotating along the first direction relative to the head mounted bracket 110. Similarly, when the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head mounted bracket 110, the second limiting block 1223 abuts against the second limiting boss 1044 to prevent the first rotating shaft 122 from excessively rotating along the second direction relative to the head mounted bracket 110. In this way, the effect of rotation limiting is achieved without adding a hinge assembly.

[0047] Furthermore, the preset rotation angle range is -15 degrees to 90 degrees, which is ergonomically designed, improves the comfort of users wearing headphones, and brings users a good product experience.

[0048] like Fig. 9 As shown, in one embodiment, the outer peripheral wall of the first rotating shaft 122 is formed with an annular positioning groove 1225, and the first elastic damping member 130 is sleeved in the annular positioning groove 1225, so that the first elastic damping member 130 is better installed and positioned on the outer peripheral wall of the first rotating shaft 122. In this embodiment, the annular positioning groove 1225 is arranged around the outer peripheral wall of the first rotating shaft 122.

[0049] like Fig. 9As shown, in one embodiment, the first elastic damping member 130 is an O-ring, so that the structure of the first elastic damping member 130 is simpler and the first elastic damping member 130 has a better damping effect.

[0050] like Fig. 9 As shown, in one embodiment, the machine screw 140 includes a limit portion 142 and a locking portion 144 connected to each other, the diameter of the limit portion 142 is larger than the diameter of the locking portion 144, and the external thread is provided on the outer peripheral wall of the locking portion 144, so that the locking portion 144 is threadedly connected with the threading hole 102 and the threading connection portion 110a. Figure 4 The ear shell bracket 120 is also formed with an abutting groove 121 communicating with the first through hole 1222, and the limiting portion 142 abuts against the abutting groove 121, so that the limiting portion 142 is limited to the side of the ear shell bracket 120 away from the head-mounted bracket 110. In this embodiment, the limiting portion 142 and the locking portion 144 are an integrally formed structure, so that the limiting portion 142 is firmly connected to the locking portion 144. It can be understood that in other embodiments, the limiting portion 142 and the locking portion 144 can also be formed separately and fixedly connected by welding or gluing.

[0051] like Figure 4 and Figure 7As shown, in one embodiment, the head-mounted assembly 100 further includes a first elastic sealing assembly 150, which is sleeved on the end surface of the locking portion 144 adjacent to the limiting portion 142, and the first elastic sealing assembly 150 elastically abuts against the abutting groove 121, so that when the locking portion 144 is screwed into the screw hole 102, the first elastic sealing assembly 150 elastically abuts against the inner wall of the abutting groove 121 and the locking portion 144, respectively, to achieve a good anti-loosening effect. Further, the first elastic sealing assembly 150 includes a first plane washer 152 and a first wave washer 154, and the number of the first plane washer 152 is two, and the two first plane washers 152 are respectively located on both sides of the first wave washer 154, and the two first plane washers 152 are both abutted against the two side surfaces of the first wave washer 154, so that the first elastic sealing assembly 150 has good elasticity. In this embodiment, the first plane washer 152 is a circular plane washer, and the first wave washer 154 is a circular wave washer. The machine screw passes through two circular plane washers and a circular wave washer, and the wave washer is located between the two plane washer sandwiches. The head-mounted bracket and the ear shell bracket are connected to the three washer assemblies through the machine screw. The first elastic damping member 130 is hidden inside the rotating structure after the finished product is assembled. Relying on the torsion of the machine screw and the rebound force of the wave washer, the looseness of the connection structure caused by the assembly virtual position between the head-mounted bracket and the ear shell bracket is solved. Since the first elastic damping member 130 and the head-mounted bracket are interference fit, the damping effect of the connection structure between the head-mounted bracket and the ear shell bracket is achieved after assembly.

[0052] like Figure 5 As shown, in one embodiment, the end surface of the limiting portion 142 away from the locking portion 144 is provided with a hexagonal groove 1422, and the hexagonal groove 1422 is connected to the threading hole, so that the machine screw 140 can be better disassembled and connected to the screw hole 102, and the machine screw 140 has better structural strength. In this embodiment, the threading hole is opened at the center of the machine screw 140.

[0053] like Figures 1 to 9As shown, the present application also provides a headset 10, including an ear shell component 200 and the head-mounted component 100 described in any of the above embodiments. In one embodiment, the head-mounted component 100 includes a head-mounted bracket 110, an ear shell bracket 120, a first elastic damping member 130 and a machine screw 140. The head-mounted bracket 110 is provided with a threading connection portion 110a, and the threading connection portion 110a is provided with a screw hole 102, a rotation limit groove 104 and a damping positioning groove 106. The rotation limit groove 104 is respectively connected to the screw hole 102 and the damping positioning groove 106, and the inner peripheral wall of the rotation limit groove 104 is respectively convexly provided with a first limit boss 1042 and a second limit boss 1044. The ear shell bracket 120 is provided with a first rotating shaft 122, and at the same time, see Fig.10 The first rotating shaft 122 is provided with a first through hole 1222, and the outer peripheral wall of the first rotating shaft 122 is convexly provided with a first limiting block 1221 and a second limiting block 1223. The first rotating shaft 122 is located in the rotation limiting groove 104 and is rotationally connected to the threading connection portion 110a. The first limiting block 1221 is used to abut against the first limiting boss 1042 when the first rotating shaft 122 rotates to a first predetermined angle relative to the head-mounted support 110 along the first direction, so that the first limiting boss 1042 plays a limiting role when the first limiting block 1221 rotates along the first direction with the first rotating shaft 122. The second limiting block 1223 is used to abut against the second limiting boss 1044 when the first rotating shaft 122 rotates to a second predetermined angle relative to the head-mounted support 110 along the second direction, so that the second limiting boss 1044 plays a limiting role when the second limiting block 1223 rotates along the second direction with the first rotating shaft. The first direction is opposite to the second direction. Due to the limiting effect of the first limiting boss 1042 and the second limiting boss 1044, the first rotating shaft 122 is prevented from excessively rotating relative to the head mounted bracket 110, so that the first rotating shaft 122 can rotate reliably within the rotation angle range relative to the head mounted bracket 110.

[0054] In one embodiment, the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and abuts against the threading connection portion 110a. The machine screw 140 is inserted into the first through hole 1222 and is rotatably connected to the ear shell bracket 120. The outer peripheral wall of the machine screw 140 is formed with an external thread 141, and the external thread is located in the threading hole 102 and is threadedly connected to the threading connection portion 110a, so that the machine screw 140 connects the ear shell bracket 120 to the head-mounted bracket 110, and the ear shell bracket 120 is rotatably connected to the head-mounted bracket 110, and the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and connected to the threading connection portion 110a, so that there is a damping effect during the relative rotation of the ear shell bracket 120 and the head-mounted bracket 110. The machine screw 140 is formed with a threading hole for threading the headband wire 20, so that the headband wire 20 can be better received and installed at the connection position between the headband bracket 110 and the ear shell bracket 120. Further, the ear shell assembly 200 includes an ear shell 210, and the ear shell bracket 120 is further provided with a second rotating shaft 126, and the second rotating shaft 126 is rotatably connected to the ear shell 210. Since the second rotating shaft 126 is rotatably connected to the ear shell 210, the first rotating shaft 122 is rotatably connected to the headband bracket 110, so that the headset 10 has better applicability and convenience of use.

[0055] In the headset 10, the threading connection portion 110a is provided with a screw hole 102, a rotation limit groove 104 and a damping positioning groove 106, the rotation limit groove 104 is respectively connected with the screw hole 102 and the damping positioning groove 106, the first rotating shaft 122 is provided with a first through hole 1222, the machine screw 140 is passed through the first through hole 1222 and is rotatably connected to the ear shell bracket 120, and the outer peripheral wall of the machine screw 140 is formed with an external thread, which is located in the screw hole 102 and connected to the threading connection portion The first rotating shaft 122 is screwed to the head bracket 110a, so that the machine screw 140 fixes the first rotating shaft 122 to the head bracket 110, and the ear shell bracket 120 is rotatably connected to the machine screw 140, so that the ear shell bracket 120 and the head bracket 110 are relatively rotatably connected. In addition, because the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and abuts against the threading connection portion 110a, there is rotation damping between the ear shell bracket 120 and the head bracket 110. In this way, there is rotation damping between the two brackets, which improves the user experience of the headset, does not need to add hinge components, greatly reduces the assembly process of the headset, and reduces the cost of the headset; since the inner peripheral wall of the rotation limiting groove 104 is respectively provided with a first limiting boss 1042 and a second limiting boss 1044, and the outer peripheral wall of the first rotating shaft 122 is respectively provided with a first limiting block 1221 and a second limiting block 1223, when the first rotating shaft 122 is rotated to a first predetermined angle relative to the head-mounted bracket 110 along the first direction, When the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head mounted bracket 110, the first limiting block 1221 abuts against the first limiting boss 1042 to prevent the first rotating shaft 122 from excessively rotating along the first direction relative to the head mounted bracket 110. Similarly, when the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head mounted bracket 110, the second limiting block 1223 abuts against the second limiting boss 1044 to prevent the first rotating shaft 122 from excessively rotating along the second direction relative to the head mounted bracket 110. In this way, the effect of rotation limiting is achieved without adding a hinge assembly.

[0056] like Figure 7 , Fig.11 and Fig.12As shown, in one embodiment, the ear shell 210 is formed with a connected shaft hole 212 and a rotation limit notch 214, and the outer peripheral wall of the second shaft 126 is convexly provided with a fan-shaped protrusion 1262, and the fan-shaped protrusion 1262 is located in the rotation limit notch 214 and is movably connected to the ear shell 210, and the fan-shaped protrusion 1262 and the ear shell 210 rotate relative to each other within a predetermined angle range, thereby avoiding excessive relative rotation between the second shaft 126 and the ear shell 210, and allowing the second shaft 126 and the ear shell 210 to rotate reliably within the predetermined angle range. In this embodiment, the first and second sector-shaped abutting surfaces are respectively provided on both sides of the sector-shaped protrusion 1262, and the first and second sector-shaped abutting surfaces are provided on the inner wall of the rotation limiting notch 214. The first sector-shaped abutting surface abuts against the first limiting surface when the second rotating shaft 126 and the ear shell 210 rotate relative to each other to the first position, and the second sector-shaped abutting surface abuts against the second limiting surface when the second rotating shaft 126 and the ear shell 210 rotate relative to each other to the second position, so that the second rotating shaft 126 and the ear shell 210 play a limiting role in preventing excessive rotation during the relative rotation process. In one embodiment, the relative rotation angle between the second rotating shaft and the ear shell is 12 degrees to 18 degrees. In this embodiment, the relative rotation angle between the second rotating shaft and the ear shell is 15 degrees, so that the ear shell assembly rotates 15 degrees relative to the inner side of the human body.

[0057] Furthermore, the first fan-shaped abutting surface is an abutting inclined surface, so that the collision force received by the first fan-shaped abutting surface and the first limiting surface is smaller. The second fan-shaped abutting surface is an abutting inclined surface, so that the collision force received by the second fan-shaped abutting surface and the second limiting surface is smaller. Furthermore, the inclination angle of the first fan-shaped abutting surface and the inclination angle of the second fan-shaped abutting surface are both 10 degrees to 30 degrees. Furthermore, the first fan-shaped abutting surface is provided with a first elastic abutting layer, so that the collision force received by the first fan-shaped abutting surface and the first limiting surface is smaller, and the second fan-shaped abutting surface is provided with a second elastic abutting layer, so that the collision force received by the second fan-shaped abutting surface and the second limiting surface is smaller.

In this embodiment, the clamping member 300 is provided with an arc-shaped bayonet 302, and the clamping member 300 is clamped into the clamping groove 1264 through the arc-shaped bayonet 302, so that the clamping member 300 is reliably clamped into the clamping groove 1264. Specifically, a deformation notch 302a is provided on the inner wall of the arc-shaped bayonet 302, and the arc-shaped bayonet 302 is interference fit with the inner wall of the clamping groove 1264. Since a deformation notch 302a is provided on the inner wall of the arc-shaped bayonet 302, a deformation avoidance zone exists when the arc-shaped bayonet 302 is clamped into the inner wall of the clamping groove 1264, thereby allowing the clamp 300 to be reliably clamped in the clamping groove 1264.

[0059] like Figures 10 to 12 As shown, further, the outer wall of the second rotating shaft 126 is also provided with a wire passing notch 1266, and the wire passing notch 1266 is communicated with the clamping groove 1264, so that the headband wire 20 is introduced into the ear shell 210 through the wire passing notch 1266 to be electrically connected with the electronic components in the ear shell 210, and at the same time, it is convenient to quickly disassemble and assemble the clamp 300 through the wire passing notch 1266, and it is also convenient to process the wire passing notch 1266.

[0060] like Figures 10 to 12 As shown, further, the ear shell bracket 120 includes a first rotating shaft 122, a connecting member 128 and a second rotating shaft 126, and the two ends of the connecting member 128 are respectively connected to the first rotating shaft 122 and the second rotating shaft 126, so that the first rotating shaft 122 and the second rotating shaft 126 are reliably fixedly connected. In order to make the connecting member 128 better adapt to the assembly of the ear shell bracket 120, and avoid the problem that the ear shell bracket 120 is easy to interfere with the ear shell 210 during use, further, the connecting member 128 is in an arc shape, so that the connecting member 128 is adapted to the shape of the outer wall of the ear shell 210, thereby making the connecting member 128 better adapt to the assembly of the ear shell bracket 120, and avoid the problem that the ear shell bracket 120 is easy to interfere with the ear shell 210 during use. In this embodiment, the connecting member 128, the first rotating shaft 122 and the second rotating shaft 126 are formed separately, and the first rotating shaft 122, the connecting member 128 and the second rotating shaft 126 are fixedly connected by welding or gluing, so that the two ends of the connecting member 128 are respectively reliably connected to the first rotating shaft 122 and the second rotating shaft 126. In this embodiment, the two ends of the connecting member 128 are respectively connected to the outer peripheral walls of the first rotating shaft 122 and the second rotating shaft 126.

[0061] like Figures 10 to 12As shown, further, a wire separation groove 1282 is formed at a portion of the connecting member 128 adjacent to the ear shell 210, and the wire separation groove 1282 extends into the abutment groove 121 and the wire passing notch 1266, respectively, so that the headband wire 20 is led out through the machine screw 140 in the abutment groove 121 and then positioned in the wire separation groove 1282, and the headband wire 20 is also led out through the wire passing notch 1266, so that the headband wire 20 is reliably installed and accommodated in the headband assembly 100. In this embodiment, the wire passing notch 1266 is opened through the axial direction of the second rotating shaft 126, and the wire passing notch 1266 is opened on the outer peripheral wall of the second rotating shaft 126, and the wire passing notch 1266 is communicated with the wire separation groove 1282 and the abutment groove 121, respectively.

[0062] However, since the connector 128 is a hard plastic part and the outer layer of the headband cable 20 is a plastic cable, the headband cable 20 is installed in the cable slot 1282 with poor firmness and is easy to loosen. Furthermore, the inner peripheral wall of the cable slot 1282 is provided with a silicone layer, and the headband cable 20 is located in the cable slot 1282 and elastically abuts against the inner wall of the cable slot 1282, so that the headband cable 20 is elastically installed in the cable slot 1282, solving the problem that the headband cable 20 is installed in the cable slot 1282 with poor firmness and is easy to loosen. Furthermore, a plurality of clamping protrusions are formed on the surface of the silicone layer, and the plurality of clamping protrusions are arranged at intervals on both sides of the extension direction of the cable slot 1282, so that the headband cable 20 is better clamped in the cable slot 1282. In this embodiment, each clamping protrusion is in a hemispherical shape, a frustum shape, or a triangular pyramid shape, so that the headband cable 20 is better clamped and installed in the cable slot 1282. Furthermore, the silicone layer is fixed to the inner wall of the wire groove 1282 by gluing, so that the silicone layer is reliably disposed on the inner wall of the wire groove 1282.

[0063] like Figures 10 to 12 As shown, further, the headset 10 also includes a second elastic damping member 400, and a fixed annular groove 1267 is formed on the outer peripheral wall of the second rotating shaft 126. The second elastic damping member 400 is sleeved in the fixed annular groove 1267, and the second elastic damping member 400 abuts against the inner wall of the rotating shaft hole 212, so that there is damping during the rotation of the second rotating shaft 126 and the ear shell 210, further improving the user experience of the headset 10. In this embodiment, the fixed annular groove 1267 is connected to the wire-passing notch to facilitate the processing of the fixed annular groove 1267. At the same time, the joint action of the second elastic damping member 400 and the clamp member 300 can effectively prevent the headband cable 20 from being separated from the wire-passing notch. In this embodiment, the second elastic damping member 400 is a rubber ring or a silicone ring.

[0064] like Figures 10 to 12As shown, in one embodiment, the ear shell component 200 further includes a second elastic sealing component 220, which is sleeved on the second rotating shaft 126, and the second elastic sealing component 220 is respectively in contact with the inner wall of the clamp 300 and the ear shell 210, so that the second elastic sealing component 220 is respectively in contact with the inner wall of the clamp 300 and the ear shell 210. Further, the second elastic sealing component 220 includes a second plane washer 222 and a second wave washer 224, and the number of the second plane washer 222 is two, and the two second plane washers 222 are respectively located on both sides of the second wave washer 224, and the two second plane washers 222 are both in contact with the two side surfaces of the second wave washer 224, so that the second elastic sealing component 220 has good elasticity.

[0065] Compared with the prior art, the present invention has at least the following advantages:

In the head-mounted assembly 100, the threading connection portion 110a is provided with a screw hole 102, a rotation limiting groove 104 and a damping positioning groove 106, the rotation limiting groove 104 is respectively connected with the screw hole 102 and the damping positioning groove 106, the first rotating shaft 122 is provided with a first through hole 1222, the machine screw 140 is passed through the first through hole 1222 and is rotatably connected to the ear shell bracket 120, and the outer peripheral wall of the machine screw 140 is formed with an external thread, the external thread is located in the screw hole 102 and is threadedly connected to the threading connection portion 110a, so that the machine screw 140 fixes the first rotating shaft 122 to the head-mounted assembly 100. The bracket 110 makes the ear shell bracket 120 and the machine screw 140 rotatably connected, and then the ear shell bracket 120 and the head-mounted bracket 110 are relatively rotatably connected. Since the first elastic damping member 130 is sleeved on the first rotating shaft 122, and the first elastic damping member 130 is located in the damping positioning groove 106 and abuts against the threading connection portion 110a, there is rotational damping between the ear shell bracket 120 and the head-mounted bracket 110.

In the above-mentioned head-mounted assembly 100, since the inner peripheral wall of the rotation limiting groove 104 is respectively provided with a first limiting boss 1042 and a second limiting boss 1044, and the outer peripheral wall of the first rotating shaft 122 is provided with a first limiting block 1221 and a second limiting block 1223, when the first rotating shaft 122 rotates to a first predetermined angle along the first direction relative to the head-mounted bracket 110, the first limiting block 1221 abuts against the first limiting boss 1042 to prevent the first rotating shaft 122 from excessively rotating relative to the head-mounted bracket 110 along the first direction; similarly, when the first rotating shaft 122 rotates to a second predetermined angle along the second direction relative to the head-mounted bracket 110, the second limiting block 1223 abuts against the second limiting boss 1044 to prevent the first rotating shaft 122 from excessively rotating relative to the head-mounted bracket 110 along the second direction, thereby achieving the effect of rotation limiting without adding a hinge assembly.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
