[0026] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0027] Please refer to Figures 1 to 3 An AR glasses hinge includes a fixed bracket 1, a movable bracket 2, a spindle 3, an elastic element 4, and a limiting element 5. The spindle 3 is mounted on the fixed bracket 1. The movable bracket 2 is sleeved on the spindle 3 and can rotate around the axis of the spindle 3. The limiting element 5 is mounted on the spindle 3 and can slide along the axis of the spindle 3. The limiting element 5 is located on the side of the movable bracket 2 away from the fixed bracket 1. The two ends of the elastic element 4 abut against the movable bracket 2 and the limiting element 5, respectively.
[0028] As described above, the beneficial effects of this invention are as follows: The AR glasses' rotating shaft utilizes an elastic element 4 to abut against a limiting element 5 and a movable support 2, causing the movable support 2 to abut against a fixed support 1, thus providing damping force when the movable support 2 and the fixed support 1 rotate relative to each other. By allowing the limiting element 5 to slide along the spindle 3, the elastic force applied by the elastic element 4 to the movable support 2 can be adjusted, thereby adjusting the rotational torque of the movable support 2 relative to the fixed support 1. This helps the AR glasses meet the wearing experience of different users, improves wearing comfort and secure fit, and allows users to easily correct the rotational torque when the rotating shaft becomes loose, extending the service life of the AR glasses.
[0029] Furthermore, the limiting member 5 is slidably connected to the fixed bracket 1, the spindle 3 is rotatable relative to the fixed bracket 1 about its own axis, and the spindle 3 is threadedly connected to the limiting member 5.
[0030] As can be seen from the above description, by rotating the spindle 3, the limiting member 5 can slide along the axial direction of the spindle 3, thereby adjusting the rotational torque of the movable bracket 2 and the fixed bracket 1 relative to each other.
[0031] Furthermore, the limiting member 5 is provided with a protruding locking block 51, and the fixed bracket 1 is provided with a locking groove 11 that slides and engages with the locking block 51; or, the limiting member 5 is provided with a locking groove 11, and the fixed bracket 1 is provided with a locking block 51 that slides and engages with the locking groove 11.
[0032] As can be seen from the above description, the sliding connection between the limiting component 5 and the fixed bracket 1 is simple and easy to produce and assemble.
[0033] Furthermore, the end of the spindle 3 away from the fixed bracket 1 is provided with a detachable knob 6.
[0034] As can be seen from the above description, the knob 6 is designed to facilitate the user's rotation of the spindle 3.
[0035] Furthermore, the knob 6 is interference-fitted with the spindle 3.
[0036] As can be seen from the above description, the connection between the knob 6 and the spindle 3 is simple and easy to produce and assemble.
[0037] Furthermore, it also includes a retaining ring 7, which is located on the side of the fixed bracket 1 away from the movable bracket 2, and the spindle 3 is provided with an annular groove 31 that cooperates with the retaining ring 7.
[0038] As can be seen from the above description, the connection between the mandrel 3 and the movable support 2 is simple and easy to manufacture and assemble.
[0039] Furthermore, the fixed bracket 1 has a protruding limiting boss 12 on the side near the limiting member 5, and the limiting boss 12 is used to limit the maximum displacement stroke of the limiting member 5.
[0040] As can be seen from the above description, the limiting boss 12 can prevent the limiting member 5 from excessively squeezing the elastic member 4, which would cause damage to the elastic member 4.
[0041] Furthermore, the contact surfaces of the fixed bracket 1 and the movable bracket 2 are respectively provided with a plurality of protruding teeth 21 and a plurality of grooves 13 that cooperate with the protruding teeth 21, and the plurality of protruding teeth 21 and the grooves 13 are respectively arranged around the axial direction of the spindle 3.
[0042] As described above, the multiple protruding teeth 21 cooperate with the slots 11 to enable the AR glasses' rotating shaft to have an inward and outward rotation angle limit, which helps to prevent the temples from accidentally rotating outward and causing the AR glasses to loosen.
[0043] Furthermore, the elastic element 4 is a spring, a sheet, or a pad.
[0044] As can be seen from the above description, the type of elastic element 4 can be selected according to actual usage needs or production conditions.
[0045] Furthermore, the fixed bracket 1 or the movable bracket 2 is provided with at least one assembly hole 14.
[0046] As described above, the fixed bracket 1 or the movable bracket 2 can be fixedly connected to the frame or temple of the AR glasses through the mounting hole 14.
[0047] Please refer to Figures 1 to 3One embodiment of this utility model is an AR glasses hinge, comprising a fixed bracket 1, a movable bracket 2, a spindle 3, an elastic element 4, and a limiting element 5. The spindle 3 is mounted on the fixed bracket 1. The movable bracket 2 is sleeved on the spindle 3 and can rotate around the axial direction of the spindle 3. The limiting element 5 is mounted on the spindle 3 and can slide along the axial direction of the spindle 3, and the limiting element 5 is located on the side of the movable bracket 2 away from the fixed bracket 1. The two ends of the elastic element 4 respectively abut against the movable bracket 2 and the limiting element 5. Specifically, the fixed bracket 1 includes a first connecting ring and a first connecting plate connected together. One end of the spindle 3 is inserted into the first connecting ring, and the first connecting plate has at least one mounting hole 14. The movable bracket 2 includes a second connecting ring and a second connecting plate connected together. The second connecting ring is sleeved on the spindle 3, and the second connecting plate has at least one mounting hole 14. The first connecting plate of the fixed bracket 1 and the second connecting plate of the movable bracket 2 are respectively fixedly connected to the frame or temple of the AR glasses through the mounting holes 14. The AR glasses hinge also includes a retaining spring 7, which is located on the side of the first connecting ring of the fixed bracket 1 away from the second connecting ring of the movable bracket 2. The spindle 3 has an annular groove 31 that mates with the retaining spring 7. The first connecting ring of the fixed bracket 1 also has an annular groove for accommodating the retaining spring 7.
[0048] The limiting member 5 is annular and is sleeved on the spindle 3. The elastic member 4 is preferably a spring and is sleeved on the spindle 3. In other embodiments, the elastic member 4 may be a spring sheet or a spring pad.
[0049] The contact surfaces of the fixed bracket 1 and the movable bracket 2 are respectively provided with multiple protruding teeth 21 and multiple grooves 13 that mate with the protruding teeth 21. The protruding teeth 21 and grooves 13 are arranged around the axial direction of the spindle 3. Specifically, the protruding teeth 21 are disposed on the second connecting ring of the movable bracket 2, and the grooves 13 are disposed on the first connecting ring of the fixed bracket 1. The number of protruding teeth 21 is N, and the number of grooves 13 is M, where M is an integer multiple of N. In this embodiment, the number of protruding teeth 21 is two, and the number of grooves 13 is four, with the two protruding teeth 21 and the four grooves 13 being evenly arranged around the axial direction of the spindle 3. In other embodiments, the number of protruding teeth 21 can be one, three, or more; the number of grooves 13 can be one, three, or more times the number of protruding teeth 21. As is easily understood, when the movable bracket 2 and the fixed bracket 1 rotate relative to each other, the side of the protrusion 21 abuts against the side of the groove 13, causing the movable bracket 2 to move away from the fixed bracket 1 along the spindle 3 and press against the elastic element 4. The elastic element 4 will generate a reaction force on the movable bracket 2. The reaction force of the elastic element 4 will generate resistance to the relative rotation of the movable bracket 2 and the fixed bracket 1. And when there is no force source for this rotation (for example, when the AR glasses are already worn in the appropriate position on the user's head), this reaction force can cause the movable bracket 2 and the fixed bracket 1 to rotate relative to each other in opposite directions through the protrusion 21 and the groove 13. This can generate and maintain a clamping force on the user's head, so that the AR glasses are always against the user's head and will not fall off the user's head.
[0050] The limiting member 5 is slidably connected to the fixed bracket 1, and the spindle 3 is rotatable relative to the fixed bracket 1 about its own axis. The spindle 3 and the limiting member 5 are connected by threads. Simply rotating the spindle 3 allows the limiting member 5 to slide along the axis of the spindle 3, thereby adjusting the rotational torque of the movable bracket 2 relative to the fixed bracket 1. Specifically, the limiting member 5 is provided with a protruding locking block 51, and the fixed bracket 1 is provided with a locking groove 11 that slides and engages with the locking block 51. In other embodiments, it is also feasible for the limiting member 5 to be provided with a locking groove 11, and the fixed bracket 1 to be provided with a locking block 51 that slides and engages with the locking groove 11.
[0051] A detachable knob 6 is provided at the end of the spindle 3 away from the fixed bracket 1. Specifically, the knob 6 is interference-fitted with the spindle 3. The knob 6 allows the user to easily rotate the spindle 3.
[0052] The fixed bracket 1 has a protruding limiting boss 12 on the side near the limiting member 5. The limiting boss 12 is used to limit the maximum displacement stroke of the limiting member 5. Specifically, the limiting boss 12 is cylindrical, and the limiting boss 12, the first connecting ring, and the spindle 3 are collinear. The spindle 3 is located inside the limiting boss 12. It is easy to understand that when the user rotates the spindle 3, the limiting member 5 moves towards the second connecting ring of the movable bracket 2, eventually causing the limiting member 5 to abut against the limiting boss 12, thereby limiting the maximum displacement stroke of the limiting member 5 and preventing the limiting member 5 from excessively compressing the elastic member 4 and causing damage to the elastic member 4. The elastic member 4 and the second connecting ring of the movable bracket 2 are both sleeved on the limiting boss 12. The limiting boss 12 can also limit the position of the elastic member 4 and prevent the elastic member 4 from shaking.
[0053] In summary, the AR glasses hinge provided by this utility model utilizes an elastic element to abut against a limiting element and a movable bracket, causing the movable bracket to abut against a fixed bracket, thus providing damping force when the movable bracket and fixed bracket rotate relative to each other. By allowing the limiting element to slide along the spindle, the elastic force applied by the elastic element to the movable bracket can be adjusted, thereby adjusting the rotational torque of the movable bracket and fixed bracket rotating relative to each other. This helps to meet the wearing experience of different users, improves wearing comfort and security, and allows users to easily correct the rotational torque when the hinge becomes loose, extending the service life of the AR glasses.
