Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of AR glasses, in particular to an adjustment component and AR glasses. Background Art
[0002] With the continuous iteration and upgrade of AR display technology, the combined application of optical waveguide technology and holographic diffraction technology has made AR glasses increasingly thinner and lighter, improving the user experience. However, in existing AR glasses, the optical engine is usually fixed to the frame, and the image position of the AR glasses is fixed after leaving the factory. However, the pupil distance of different users varies. This causes the actual image seen by different users to deviate from the preset position, which can easily cause eye fatigue with long-term use. In addition, different people have different facial shapes. For example, the height from the support point of the nose bridge for the AR glasses to the eyes varies, and the deformation of the frame varies with the width of the face. These factors affect the image quality of the binocular glasses, resulting in a poor user experience. Utility Model Content
[0003] Since existing AR glasses cannot provide the best user experience for different users due to the fixed image position when they leave the factory, it is necessary to provide adjustment components and AR glasses.
[0004] Adjustment components, used to adjust the position of the optical and mechanical components in AR glasses, including:
[0005] a first mounting frame, the first mounting frame comprising a mounting portion and a horizontal guide rail portion fixed to the mounting portion, the mounting portion being used to connect to a frame assembly of the AR glasses;
[0006] a second mounting frame, the second mounting frame comprising a connecting portion and a vertical guide rail portion fixed to the connecting portion, the connecting portion being slidably mounted on the horizontal guide rail portion;
[0007] a third mounting bracket, the third mounting bracket being slidably mounted on the vertical guide rail portion and being used to connect the optical-mechanical assembly;
[0008] a first driving member, the first driving member being drivingly connected to the second mounting bracket to drive the third mounting bracket and the optical-mechanical assembly mounted on the third mounting bracket to move along an extension direction of the track of the horizontal guide rail portion; and
[0009] A second driving member is drivingly connected to the third mounting bracket to drive the optical-mechanical assembly to move along an extension direction of the vertical guide rail portion.
[0010] With this arrangement, the adjustment assembly consisting of three brackets and two driving parts makes it convenient for users to adjust the combination of the optical and mechanical components to the optimal position when wearing the AR glasses, thereby improving the wearing comfort of the AR glasses.
[0011] In one embodiment, the vertical guide portion is located on a side of the connecting portion that deviates from the horizontal guide portion, and the third mounting bracket is installed on a side of the vertical guide portion that faces the horizontal guide portion to form an accommodating space between the vertical guide portion and the horizontal guide portion for accommodating the optical-mechanical assembly.
[0012] With such a configuration, by arranging the vertical guide portion and the horizontal guide portion in the above manner, the space at the connection between the temple and the frame can be fully utilized, and the two guide portions for guiding the optical-mechanical assembly to move in different directions do not need to be overlapped, so that the adjustment range of the adjustment assembly in two directions is adapted to the space at the connection between the temple and the frame, avoiding the problem that the adjustment range of the adjustment assembly in a single direction is too large, which causes the user to easily touch the cheek when adjusting.
[0013] In one embodiment, the horizontal guide rail portion extends horizontally from the upper end of the mounting portion to form a first accommodating groove, and the vertical guide rail portion extends vertically from the connecting portion to form a second accommodating groove, and the first accommodating groove and the second accommodating groove overlap to form the accommodating space.
[0014] This arrangement makes full use of the space at the connection between the temple and the frame, and the entire adjustment component requires less space when adjusting the position of the optical-mechanical component. In particular, the adjustment component requires less space along the extension direction of the temple, so it is not easy to touch the person's cheek when adjusting the optical-mechanical component in the horizontal direction.
[0015] In one embodiment, the horizontal guide rail portion includes a first plate fixedly connected to the mounting portion, two first supports spaced apart from each other on the first plate, and a plurality of first guide shafts mounted on the two first supports.
[0016] The connecting portion includes a second plate body fixedly connected to the vertical guide rail portion and at least two groups of first sliders fixed to the second plate body. The number of the first sliders in each group is at least two and they are arranged at intervals. The first sliders can be slidably mounted on the first guide shaft.
[0017] With such an arrangement, the second mounting bracket is less likely to deflect when sliding along the two first guide shafts, thereby improving the position adjustment accuracy of the adjustment component relative to the optical machine component.
[0018] In one embodiment, the connecting portion also includes a first positioning column fixed to the second plate body and having a first threaded hole, the first support body has a first positioning hole coaxially arranged with the first threaded hole, the first driving member is an adjusting knob, one end of the adjusting knob is screwed to the first threaded hole, and the other end is clamped to the first positioning hole.
[0019] With this arrangement, the second mounting bracket can be driven to move horizontally by rotating the adjusting knob with high precision, and the screw connection between the adjusting bolt and the first positioning column and the clamping connection between the adjusting bolt and the first support body can achieve fixation at any time.
[0020] In one embodiment, the vertical guide rail portion includes a third plate, two second supports spaced apart from each other on the third plate, and a plurality of second guide shafts mounted on the two second supports, wherein the second support located at the upper end is fixedly connected to the connecting portion;
[0021] The third mounting frame includes a fourth plate body and at least two groups of second sliding blocks fixed to the fourth plate body, each group of the second sliding blocks has at least two and are arranged at intervals, and the second sliding blocks are slidably mounted on the second guide shaft.
[0022] With this arrangement, the second guide shaft cooperates with the second slider to make the third mounting bracket and the optical-mechanical assembly slide more smoothly in the vertical direction and less likely to deflect.
[0023] In one embodiment, the third mounting bracket also includes a second positioning column fixed to the fourth plate and having a second threaded hole. The second support body located at the lower end has a second positioning hole coaxially arranged with the second threaded hole. The second driving member is an adjusting knob, one end of the adjusting knob is screwed to the second threaded hole, and the other end is clamped to the second positioning hole.
[0024] Such an arrangement is conducive to improving the vertical position adjustment accuracy of the optical-mechanical components, thereby accurately adjusting the composite image.
[0025] In one embodiment, the first positioning hole is an open slot and the slot width of the open slot is smaller than the diameter of the first positioning hole; and / or
[0026] The second positioning hole is an open slot, and a slot width of the open slot is smaller than a diameter of the second positioning hole.
[0027] Such an arrangement helps to improve assembly efficiency by designing the first positioning hole as an open slot.
[0028] In one embodiment, the adjusting knob includes a knob snap ring, a threaded shaft, a knob cover spaced apart from the threaded shaft, and a stop step. The knob snap ring is sleeved on the threaded shaft and located between the stop step and the knob cover.
[0029] In this arrangement, the knob clamping ring is used to support the adjustment knob and the horizontal guide rail portion of the first mounting frame, so that the knob cover always abuts against the first support body of the horizontal guide rail portion when rotating, which is beneficial to improving the structural stability after the connection between the connecting portion of the second mounting frame and the horizontal guide rail portion of the first mounting frame.
[0030] This application also provides AR glasses, including:
[0031] Optical mechanical components;
[0032] A frame assembly, comprising a frame and temples and lenses mounted on the frame, wherein the frame is provided with a first mounting position and a second mounting position on the front and back sides thereof respectively; and

[0034] With this setup, the AR glasses can flexibly cope with interference from factors such as the size of the optical machine, the optical waveguide coupling position, and the ID design, ensuring the quality of the combined image and improving the user's wearing comfort.

[0050] With the continuous iteration and upgrade of AR display technology, the combined application of optical waveguide technology and holographic diffraction technology has made AR glasses increasingly thinner and lighter, improving the user experience. However, in existing AR glasses, the optical engine is usually fixed to the frame, and the image position of the AR glasses is fixed after leaving the factory. However, the pupil distance of different users varies. This causes the actual image seen by different users to deviate from the preset position, which can easily cause eye fatigue with long-term use. In addition, different people have different facial shapes. For example, the height from the support point of the nose bridge for the AR glasses to the eyes varies, and the deformation of the frame varies with the width of the face. These factors affect the image quality of the binocular glasses, resulting in a poor user experience.
[0051] Based on this, it is necessary to provide adjustment components and AR glasses that can easily adjust the position of the optical machine to adapt to different facial shapes.
[0052] See also Figure 1 and Figure 2 , Figure 1Schematic diagram of the structure of AR glasses in one embodiment of the present invention. Figure 2 for Figure 1 Schematic diagram of the structure of the adjustment assembly 100 and the optical-mechanical assembly 300. The AR glasses include the adjustment assembly 100, the frame assembly 200, and the optical-mechanical assembly 300. The frame assembly 200 includes a frame 210, temples 220 and lenses 230 mounted on the frame 210. Specifically, the adjustment assembly 100 includes a first mounting frame 10, a second mounting frame 20, a third mounting frame 30, a first driving member 40, and a second driving member 50. The first mounting frame 10 includes a mounting portion 11 and a horizontal guide rail portion 12, the mounting portion 11 is used to connect the frame assembly 200 of the AR glasses, and the horizontal guide rail portion 12 is fixed to the mounting portion 11; the second mounting frame 20 includes a connecting portion 21 and a vertical guide rail portion 22, the connecting portion 21 is slidably mounted on the horizontal guide rail portion 12, and the vertical guide rail portion 22 is fixed to the connecting portion 21; the third mounting frame 30 is slidably mounted on the vertical guide rail portion 22 and is used to connect the optical-mechanical assembly 300, the first driving member 40 is drivingly connected to the second mounting frame 20 to drive the third mounting frame 30 and the optical-mechanical assembly 300 installed on the third mounting frame 30 to move along the track extension direction of the horizontal guide rail portion 12, and the second driving member 50 is drivingly connected to the third mounting frame 30 to drive the optical-mechanical assembly 300 to move along the track extension direction of the vertical guide rail portion 22. The adjustment assembly 100 composed of three brackets and two driving parts makes it convenient for users to adjust the combination of the optical-mechanical assembly 300 to the optimal position when wearing the AR glasses, thereby improving the wearing comfort of the AR glasses.
[0053] See also Figure 2 , further, on the basis of wearing comfort, the device volume and weight of AR glasses need to be reduced as much as possible. First, the optical-mechanical assembly 300 is arranged at the connection between the frame and the temple 220 to make full use of the space there. Secondly, the optical-mechanical assembly 300 cannot squeeze the user's cheek when adjusting, which requires that the occupied space of the adjustment assembly 100 be reduced as much as possible when designing the adjustment assembly 100. Based on this, in this embodiment provided by the present application, the vertical guide rail portion 22 is located on the side of the connecting portion 21 that deviates from the horizontal guide rail portion 12 and the third mounting frame 30 is installed on the side of the vertical guide rail portion 22 toward the horizontal guide rail portion 12 to form an accommodating space for accommodating the optical-mechanical assembly 300 between the vertical guide rail portion 22 and the horizontal guide rail portion 12. By arranging the vertical guide rail portion 22 and the horizontal guide rail portion 12 in the above manner, the space at the connection between the temple 220 and the frame can be fully utilized. The two guide rail portions for guiding the optical-mechanical assembly 300 to move in different directions do not need to be overlapped, so that the adjustment range of the adjustment assembly 100 in two directions is adapted to the space at the connection between the temple 220 and the frame, avoiding the problem that the adjustment range of the adjustment assembly 100 in a single direction is too large, causing the user to easily touch the cheek when adjusting, or the problem that the cheek of a user with a short nose bridge easily touches the optical-mechanical assembly 300 when wearing it.
[0054] See also Figures 2 to 5 , Figure 3 for Figure 2 A schematic structural diagram of the first mounting frame 10, Figure 4 for Figure 2 A schematic structural diagram of the second mounting frame 20, Figure 5 for Figure 2 Schematic diagram of the structure of the third mounting frame 30. Specifically, the horizontal guide portion 12 extends horizontally from the upper end of the mounting portion 11 to form a first receiving groove 101, and the vertical guide portion 22 extends vertically from the connecting portion 21 to form a second receiving groove 201. The first receiving groove 101 and the second receiving groove 201 overlap to form a receiving space. In this way, the space at the connection between the temple 220 and the frame 210 is fully utilized, and the entire adjustment assembly requires less space when adjusting the position of the optical-mechanical assembly 300. In particular, the adjustment assembly requires less space along the extension direction of the temple 220, so it is less likely to hit the person's cheek when adjusting the optical-mechanical assembly 300 in the horizontal direction.
[0055] See also Figures 2 to 4 . Optionally, in this embodiment provided by the present application, the horizontal guide rail portion 12 includes a first plate 121, two first support bodies 122 and a plurality of first guide shafts 123, and the connecting portion 21 includes a second plate 211, at least two groups of first sliders 212 and at least two groups of first sliders 212. Specifically, the first plate 121 is fixedly connected to the mounting portion 11, the two first support bodies 122 are spaced apart on the first plate 121, the number of the first guide shafts 123 is two and the two ends of each first guide shaft 123 are respectively mounted on the two first support bodies 122; the second plate 211 is fixedly connected to the vertical guide rail portion 22, the two groups of first sliders 212 are fixedly mounted on the second plate 211, the number of each group of first sliders 212 is at least two and spaced apart, and the first slider 212 can be slidably sleeved on the first guide shaft 123. The second mounting frame 20 is not prone to deflection when sliding along the two first guide shafts 123, thereby improving the position adjustment accuracy of the adjustment component on the optical machine component 300. It is understandable that in other embodiments, the first sliding block 212 may also be a cylindrical sliding sleeve, as long as it can slideably cooperate with the first guide shaft 123 .
[0056] For further information, see Figures 2 to 4Optionally, in one embodiment provided in the present application, the connecting portion 21 further comprises a first positioning post 213, which is fixed to the second plate 211 and has a first threaded hole 2131 formed therein, and the first support body 122 has a first positioning hole 1221 coaxially arranged with the first threaded hole 2131; the first driving member 40 is an adjusting knob 60, one end of the adjusting knob 60 is screwed to the first threaded hole 2131, and the other end is clamped to the first positioning hole 1221. The second mounting bracket 20 is driven to move horizontally by rotating the adjusting knob 60, with high precision, and the screw connection between the adjusting bolt and the first positioning post 213 and the clamping connection between the adjusting bolt and the first support body 122 can achieve fixation at any time.
[0057] See also Figure 2 、 Figures 4 and 5 Optionally, in one embodiment provided herein, the vertical guide rail portion 22 includes a third plate 221, two second support bodies 222, and a plurality of second guide shafts 223. The third mounting frame 30 includes a fourth plate 31 and at least two sets of second sliders 32 fixed to the fourth plate 31. Specifically, the two second support bodies 222 are spaced apart on the third plate 221. There are two second guide shafts 223, and both ends of each second guide shaft 223 are respectively mounted on the second support bodies 222. The second support body 222 at the upper end is fixedly connected to the connecting portion 21. Each set of second sliders 32 includes at least two second sliders 32, which are spaced apart on the fourth plate 31. The second sliders 32 are slidably mounted on the second guide shafts 223. Similar to the assembly between the second mounting frame 20 and the first mounting frame 10 described above, the cooperation between the second guide shafts 223 and the second sliders 32 makes the vertical sliding of the third mounting frame 30 and the optical-mechanical assembly 300 more stable and less prone to deflection.
[0058] For further information, see Figure 2 、 Figure 4 and Figure 5 Optionally, in this embodiment provided herein, the third mounting bracket 30 further includes a second positioning post 33 having a second threaded hole 331. The second support body 222 at the lower end has a second positioning hole 2221 coaxially arranged with the second threaded hole 331. The second driving member 50 is an adjustment knob 60, one end of which is threaded into the second threaded hole 331 and the other end is snap-fitted into the second positioning hole 2221. Similar to the first driving member 40 described above, the second driving member 50 is also an adjustment knob 60, which facilitates improving the vertical position adjustment accuracy of the optical-mechanical assembly 300.
[0059] See also Figure 3 and Figure 4Optionally, in the embodiment provided by the present application, the first positioning hole 1221 is an open slot, and the slot width of the open slot is smaller than the diameter of the first positioning hole 1221; the second positioning hole 2221 is an open slot, and the slot width of the open slot is smaller than the diameter of the second positioning hole 2221. Taking the assembly between the first mounting frame 10 and the second mounting frame 20 as an example, first, the first driving member 40, that is, the adjusting knob 60, is snapped into the first positioning hole 1221 of the first mounting frame 10, and then the first threaded hole 2131 of the connecting portion 21 of the second mounting frame 20 is screwed to the adjusting knob 60. Finally, the first guide shaft 123 is inserted through the mounting hole pre-opened on the first support body 122 to connect the second mounting frame 20 to the first mounting frame 10. Designing the first positioning hole 1221 as an open slot helps to improve assembly efficiency.
[0060] See also Figure 6 , Figure 6 The following is a schematic diagram of the structure of an adjustment knob 60 in one embodiment of the present application. Specifically, the adjustment knob 60 includes a knob snap ring 64, a threaded shaft 61, a knob cover 62 spaced apart from the threaded shaft 61, and a stop step 63. The knob snap ring 64 is sleeved on the threaded shaft 61 and located between the stop step 63 and the knob cover 62. In this way, the knob snap ring 64 provides support between the adjustment knob 60 and the horizontal guide rail portion 12 of the first mounting frame 10, ensuring that the knob cover 62 always abuts against the first support body 122 of the horizontal guide rail portion 12 during rotation, thereby improving the structural stability of the connection between the connecting portion 21 of the second mounting frame 20 and the horizontal guide rail portion 12 of the first mounting frame 10.
[0061] See also Figure 1 and Figure 7 , Figure 7 This is a schematic diagram of the structure of AR glasses in another embodiment provided by this application. Taking into account factors such as the size of the optical engine, the optical waveguide coupling position, and the ID design, the frame 210 is provided with a first mounting position and a second mounting position on both sides. The adjustment component 100 can be selectively installed in the first mounting position or the second mounting position to address interference from different influencing factors. The AR glasses are flexible in design and widely adaptable.
[0062] Please refer again Figure 1 The AR glasses provided in this application also include a nose pad 240 installed on the frame 210. The nose pad 240 is detachable. Since the adjustment component 100 occupies a small space, users with shorter noses can also get a more comfortable wearing experience.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
