[0001] The present invention relates to the field of AR glasses, and in particular to a frame of AR glasses and AR glasses. Background Art

[0002] AR glasses are intelligent devices that connect the virtual world and the real world. Through these AR glasses, one can see the real world and virtual content, and can interact with visual, auditory and other information.

[0003] A Chinese patent with related announcement number CN111338082B discloses an AR glasses, including a frame, the frame including a frame and temples, the temples being connected to the frame; an adjustment mechanism, the adjustment mechanism including a first adjustment component and a second adjustment component, the first adjustment component being connected to the temples, the second adjustment component being connected to the frame; a display module, the display module being movably connected to the temples through the first adjustment component; a nose pad, the nose pad being movably connected to the frame through the second adjustment component; wherein the adjustment mechanism is configured to adjust the image of the display module to within the field of view, and the first adjustment component is configured to adjust the image presentation position of the image in the direction of pupil distance, and the second adjustment component is configured to adjust the image presentation position of the image in the direction of human body height.

[0004] With respect to the above-mentioned related technologies, when the existing AR glasses adjust the imaging position in the direction of human height, the adjustment mechanism can only adjust the height of the two lenses at the same time. Some people with asymmetric pupils find it difficult to individually adjust the position of each lens according to their own needs when using the existing AR glasses. In addition, due to differences in age and height of users, there are certain differences in the head circumference of different users. It is also difficult for the existing AR glasses to adaptively adjust the distance between the two lenses according to the head circumference of the user, which is prone to wearing discomfort. At the same time, it is also easy to cause the lenses to tilt and affect the visual experience. In summary, it is difficult for the existing AR glasses to easily adjust the position of individual lenses. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a frame of AR glasses and AR glasses to solve the technical problem that it is difficult to easily adjust the position of a single lens in existing AR glasses.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a frame for AR glasses, comprising a frame, wherein sliders are fixedly connected to the middle of the frame, the sliders are slidably connected to one end of a first adjustment box along a vertical direction, the other end of the first adjustment box is slidably connected to a second adjustment box, an adjustment component capable of adjusting the position up and down is connected to the second adjustment box, the adjustment component in the second adjustment box can slide the first adjustment box on one side of the second adjustment box alone after adjusting the position upward or downward, and vice versa, the first adjustment boxes on both sides are slid at the same time, and a driving structure for driving the slider up and down is installed in the first adjustment box.

[0007] By adopting the above technical solution, the position of the adjustment box structure connected to the AR lens can be easily and independently adjusted. When the AR glasses are adapted to the user's wearing habits, the corresponding knobs on the frame can be turned to easily adjust the lens position of the AR glasses to better meet the usage needs of different users.

[0008] The present invention is further configured as follows: an adjustment opening is provided in the middle of the second adjustment box along the vertical direction, a second adjustment shaft is slidably connected in the adjustment opening, the second adjustment shaft is fixedly connected to a second adjustment gear in the second adjustment box, and one end is fixedly connected to a knob after extending out of the second adjustment box, the first adjustment boxes are fixedly connected to a second fixed box extending into another first adjustment box, the second fixed boxes are slidably connected to a second telescopic rack, a spring is connected between the second telescopic rack and the inner wall of the second fixed box, and when the second adjustment shaft is located in the middle of the adjustment opening, the second adjustment gear is in contact with two second telescopic racks at the same time.

[0009] By adopting the above technical solution, the horizontal lateral position adjustment of the AR lens on one side can be conveniently achieved by turning the knob in this state.

[0010] The present invention is further configured such that second adjustment boxes are extended from both ends of the second adjustment shaft, and the knob is arranged at the end of the second adjustment shaft facing the user.

[0011] By adopting the above technical solution, the second adjustment shaft can better slide in the vertical direction to adjust the height.

[0012] The present invention is further configured such that the vertical portion of the inner wall of the adjusting port is fixedly connected to a limiting boss, four limiting bosses are arranged in each adjusting port, and are distributed in pairs on the two vertical inner walls of the adjusting port, and when the second adjusting shaft is located in the middle of the adjusting port, the four limiting bosses in the adjusting port are in contact with the second adjusting shaft at the same time, and the second adjusting shaft will undergo elastic deformation when sliding upward or downward through the limiting bosses.

[0013] By adopting the above technical solution, the limiting boss in the adjustment port is used to limit the position of the second adjustment shaft. When the bottom surface of the second adjustment shaft contacts the two limiting bosses above, the second adjustment gear disengages from the second telescopic rack below. Conversely, when the top surface of the second adjustment shaft contacts the two limiting bosses below, the second adjustment gear disengages from the second telescopic rack above.

[0014] The first gear is connected with the gear of the first transmission gear, and the second gear is connected with the gear of the second transmission gear in a fixed manner.

[0015] By adopting the above technical solution, after the first adjusting gear is pressed toward the inside of the first adjusting box, the limit gear is disengaged from the second fixed rack, and the first adjusting gear is meshed with the first fixed rack. At this time, the first adjusting gear can be rotated to conveniently realize the independent position adjustment of the AR lens in the vertical direction.

[0016] The present invention is further configured such that a connecting rod parallel to the first adjustment axis is fixedly connected to the slider, a fixing plate is fixedly connected to one end of the connecting rod away from the slider, an adjustment axis slot for sliding the first adjustment axis is relatively arranged between the fixing plate and the slider, and the fixing plate is slidably connected in the first adjustment box along a vertical direction.

[0017] By adopting the above technical solution, the fixed plate connected to the connecting rod can cooperate with the sliding block to provide stable support for the first adjusting shaft, so that the first adjusting shaft can be stably slidably connected in the adjusting shaft slot, providing a stable connection point for the other end of the first adjusting shaft, thereby effectively improving the sliding stability of the first adjusting shaft.

[0018] The present invention is further configured such that the first telescopic rack is always in contact with the limiting gear.

[0019] By adopting the above technical solution, when the first adjusting gear is meshed with the first fixed rack, the first adjusting gear rotates. Since the diameter of the first adjusting gear is larger than the limiting gear, the limiting gear may slip relative to the first telescopic rack, which will not affect the normal rotation of the first adjusting gear.

[0020] The present invention is further configured such that the two first adjustment boxes slidably connected in the second adjustment box can contact each other, and when the two first adjustment boxes contact each other, the second fixed box in the first adjustment box will not exceed the plane where the fixed sheet in the other first adjustment box is located.

[0021] By adopting the above technical solution, the second fixing box of the closed meina is not extended too deeply into the other first adjustment box, thereby affecting the normal up and down sliding of the slider.

[0022] A pair of AR glasses comprises a frame, wherein an AR lens is connected to one side of the frame, and a first adjustment box is oppositely connected to the AR lens, and the first adjustment box is slidably connected to a second adjustment box. The frame is rotatably connected to temples and is connected to a nose pad in the middle. The frame is provided with a snap-in flange at a position where the AR lens is connected, and a buckle for protecting an edge of the AR lens is snap-in connected to the frame via the snap-in flange, and the buckle is connected to the frame via a screw at a position away from the snap-in flange.

[0023] By adopting the above technical solution, a snap-on structure is connected at the position where the frame of the AR glasses is connected to the AR lens, the snap-on flange on the edge of the frame is used to snap into place with the snap-on, and the snap-on is further fixed to the frame by screws, thereby effectively improving the stability of the connection between the AR lens and the frame.

[0024] In summary, the present invention mainly has the following beneficial effects: The present invention provides an adjustment box structure capable of sliding in opposite directions to adjust the position in the middle of the AR glasses frame. The position where the adjustment box structure is connected to the AR lens can be easily and independently adjusted. When the AR glasses are adapted to the wearing habits of the user, the corresponding knob on the frame can be turned to conveniently adjust the lens position of the AR glasses, so as to better meet the usage needs of different users. The present invention connects a buckle structure at the position where the frame of the AR glasses is connected to the AR lens, utilizes the buckle to engage with the buckle by the buckle flange on the edge of the frame, and further fixes the buckle to the frame by screws, thereby effectively improving the stability of the connection between the AR lens and the frame. The present invention achieves the meshing relationship between the gear and the rack on the adjustment shaft which can adjust the position up and down in the adjustment box, so that the two groups of AR lenses can be synchronously moved closer to or away from each other when the knob is turned, and when the position of the AR lens needs to be adjusted in the horizontal direction alone, the position of the AR lens can be adjusted alone by changing the position of the adjustment shaft.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] The following describes an embodiment of the present invention based on its overall structure. Embodiment 1

[0029] A frame of AR glasses, such as Figure 1-12 As shown, it includes a frame 1, and a slider 8 is fixedly connected to the middle of the frame 1. The slider 8 is slidably connected to one end of the first adjusting box 2 along the vertical direction, and the other end of the first adjusting box 2 is slidably connected to the second adjusting box 3. The second adjusting box 3 is connected with an adjusting component that can adjust the position up and down. Specifically, the adjusting component includes a second adjusting shaft 16. After the adjusting component in the second adjusting box 3 adjusts the position upward or downward, it can make the first adjusting box 2 on one side of the second adjusting box 3 slide alone, and vice versa, it makes the first adjusting boxes 2 on both sides slide at the same time. A driving structure that drives the slider 8 to move up and down is installed in the first adjusting box 2. Specifically, the driving structure includes a first adjusting shaft 9.

[0030] See also Figure 2-12 The middle part of the second adjusting box 3 is provided with an adjusting port 301 in the vertical direction, and a second adjusting shaft 16 is slidably connected in the adjusting port 301. The second adjusting shaft 16 is fixedly connected with a second adjusting gear 1601 in the second adjusting box 3, and one end thereof is extended out of the second adjusting box 3 and fixedly connected with a knob 1602. The second adjusting gear 1601 can be rotated by turning the knob 1602. The first adjusting box 2 is fixedly connected with a second fixed box 14 extending into another first adjusting box 2. The second fixed box 14 is slidably connected with a second telescopic rack 15 toward each other, and a spring is connected between the second telescopic rack 15 and the inner wall of the second fixed box 14. When the second adjustment shaft 16 is located in the middle of the adjustment opening 301, the second adjustment gear 1601 is in contact with the two second telescopic racks 15 at the same time. At this time, rotating the second adjustment gear 1601 can drive the two second telescopic racks 15 at the same time. By changing the height of the second adjustment shaft 16, the second adjustment gear 1601 connected to the second adjustment shaft 16 squeezes the second telescopic rack 15 to shrink it toward the second fixed box 14. At this time, the second adjustment gear 1601 is out of contact with the other second telescopic rack 15. By turning the knob 1602 in this state, the horizontal lateral position adjustment of the AR lens 5 on one side can be easily achieved.

[0031] See also Figure 1-3 , second adjustment boxes 3 are extended from both ends of the second adjustment shaft 16, and the knob 1602 is set at the end of the second adjustment shaft 16 facing the user, which effectively improves the aesthetics of the AR glasses. Second adjustment boxes 3 are extended from both ends of the second adjustment shaft 16. When adjusting the height of the second adjustment shaft 16, the two ends of the second adjustment shaft 16 can be subjected to force, so that the second adjustment shaft 16 can better slide in the vertical direction to adjust the height.

[0032] See also Figure 2-11The slider 8 is connected to the first adjusting shaft 9 for rotation toward the inside of the first adjusting box 2. The first adjusting shaft 9 is sequentially connected to the first adjusting gear 901 and the limiting gear 902 along the axial direction. The inner wall of the first adjusting box 2 is fixedly connected to the first fixed rack 10 for cooperating with the first adjusting gear 901. The inner wall of the first adjusting box 2 is connected to a first fixed box 11 parallel to the first fixed rack 10 on one side of the first fixed rack 10. A first telescopic rack 12 is slidably connected in the first fixed box 11. A spring is connected between the first telescopic rack 12 and the first fixed box 11. The inner wall of the first adjusting box 2 is fixedly connected to the second fixed rack 13 opposite to the first fixed box 11. The first adjusting box 2 is vertically opposite to the first fixed rack. A gear slot 201 is provided at the position of 10, and the first adjusting gear 901 passes through the gear slot 201 and extends out of the first adjusting box 2. The first adjusting shaft 9 can slide toward the first fixed rack 10 in the horizontal direction. When the first adjusting shaft 9 does not slide, the limiting gear 902 is in contact with the first telescopic rack 12 and the second fixed rack 13 at the same time, and the first adjusting gear 901 is not in contact with the first fixed rack 10. After the first adjusting gear 901 is pressed toward the inside of the first adjusting box 2, the limiting gear 902 is disengaged from the second fixed rack 13, and the first adjusting gear 901 is meshed with the first fixed rack 10. At this time, rotating the first adjusting gear 901 can conveniently realize the independent position adjustment of the AR lens in the vertical direction.

[0033] See also Figure 2-11 When the first adjusting gear 901 is in meshing with the first fixed rack 10, the end thereof away from the first fixed rack 10 also extends out of the gear slide slot 201, so that the user can conveniently rotate the first adjusting gear 901 after pressing the first adjusting gear 901. Specifically, in order to enable the user to clearly understand the number of circles or angles rotated by the first adjusting gear 901, the first adjusting gear 901 is provided with a plurality of marks of different colors at the same angle intervals. In the present embodiment, the first adjusting gear 901 is provided with marked teeth of red, yellow and blue colors at intervals of one hundred and twenty degrees respectively.

[0034] See also Figure 6-11, the first telescopic rack 12 is always in contact with the limit gear 902. When the first adjusting gear 901 is meshed with the first fixed rack 10, the first adjusting gear 901 rotates. Since the diameter of the first adjusting gear 901 is larger than the limit gear 902, the limit gear 902 may slip relative to the first telescopic rack 12, which will not affect the normal rotation of the first adjusting gear 901. The first telescopic rack 12 can also shrink toward the first fixed box 11 after the first adjusting gear 901 is meshed with the first fixed rack 10. The two first adjusting boxes 2 slidingly connected in the second adjusting box 3 can contact each other. When the two first adjusting boxes 2 contact each other, the second fixed box 14 in the first adjusting box 2 will not exceed the plane of the fixed sheet 802 in the other first adjusting box 2. The second fixed box 14 extends too deep into the other first adjusting box 2, thereby affecting the normal up and down sliding of the slider 8.

[0035] A kind of AR glasses, such as Figure 1-12 As shown, the frame 1 includes a frame 1, one side of the frame 1 is connected to an AR lens 5, specifically, the AR lens 5 is a diffraction light waveguide lens, the AR lens 5 itself and the electronic devices inside the frame 1 are not improved in this application, and are not described in detail here, the AR lens 5 is oppositely connected to a first adjustment box 2, the first adjustment box 2 is slidably connected to a second adjustment box 3, the frame 1 is rotatably connected to a temple 6, and is connected to a nose pad 4 in the middle, specifically, the nose pad 4 is fixedly connected to the bottom end of the second adjustment box 3, and the frame 1 is connected to the AR A snap-in flange 701 is provided at the position of the lens 5, and the frame 1 is snap-connected with a buckle 7 for protecting the edge of the AR lens 5 through the snap-in flange 701. The buckle 7 is connected to the frame 1 by screws at a position away from the snap-in flange 701. The buckle structure is connected at the position where the frame 1 of the AR glasses is connected to the AR lens 5, and the snap-in flange 701 on the edge of the frame 1 is snap-fitted with the buckle 7, and the buckle 7 is further fixed to the frame 1 by screws, thereby effectively improving the stability of the connection between the AR lens 5 and the frame 1. Embodiment 2

[0036] A frame of AR glasses, such as Figure 1-12As shown, on the basis of Example 1, the difference from Example 1 is that the vertical portion of the inner wall of the adjusting port 301 is fixedly connected to the limiting boss 302, and four limiting bosses 302 are arranged in each adjusting port 301, and are distributed in pairs on the two vertical inner walls of the adjusting port 301. Specifically, two limiting bosses 302 are arranged at different heights in the adjusting port 301, respectively, for distinguishing three contact states between the second adjusting shaft 16 and the second telescopic rack 15. Specifically, the three contact states are that the second adjusting shaft 16 only contacts the upper second telescopic rack 15, the second adjusting shaft 16 only contacts the lower second telescopic rack 15, and the second adjusting shaft 16 contacts both second telescopic racks 15 at the same time. The telescopic rack 15, when the second adjusting shaft 16 is located in the middle of the adjusting mouth 301, the four limiting bosses 302 in the adjusting mouth 301 are in contact with the second adjusting shaft 16 at the same time, and the second adjusting shaft 16 will undergo elastic deformation when sliding upward or downward through the limiting bosses 302. The limiting bosses 302 in the adjusting mouth 301 are used to limit the position of the second adjusting shaft 16. When the bottom surface of the second adjusting shaft 16 contacts the two limiting bosses 302 above, the second adjusting gear 1601 disengages from contact with the second telescopic rack 15 below. Conversely, when the top surface of the second adjusting shaft 16 contacts the two limiting bosses 302 below, the second adjusting gear 1601 disengages from contact with the second telescopic rack 15 above.

[0037] See also Figure 6-11 The slider 8 is fixedly connected with a connecting rod 801 which is parallel to the first adjusting shaft 9. The end of the connecting rod 801 away from the slider 8 is fixedly connected with a fixing plate 802. An adjusting shaft slot 803 for the first adjusting shaft 9 to slide is relatively arranged between the fixing plate 802 and the slider 8. The fixing plate 802 is slidably connected to the first adjusting box 2 in the vertical direction. The fixing plate 802 connected by the connecting rod 801 can cooperate with the slider 8 to provide a stable support for the first adjusting shaft 9, so that the first adjusting shaft 9 is stably slidably connected to the adjusting shaft slot 803, providing a stable connection point for the other end of the first adjusting shaft 9, effectively improving the sliding stability of the first adjusting shaft 9. The fixing plate 802 is connected to the slider 8 through the connecting rod 801, and is also slidably connected to the first adjusting box 2 in the vertical direction, so that the fixing plate 802 can also enhance the connection stability between the slider 8 and the first adjusting box 2.

[0038] The working principle of the present invention is: directly turn the knob 1602. Since the second adjusting gear 1601 is in contact with the upper and lower second telescopic racks 15 at the same time, the horizontal lateral spacing between the two groups of AR lenses 5 can be synchronously adjusted when the knob 1602 is turned. When the user needs to adjust the horizontal lateral position of one of the AR lenses 5 separately, pinch the two ends of the second adjusting shaft 16 to adjust the height of the second adjusting shaft 16, so that the second adjusting gear 1601 is out of contact with the second telescopic rack 15 corresponding to the other AR lens 5. At this time, turning the knob 1602 can conveniently adjust the horizontal lateral position of the AR lens 5 to be adjusted without affecting the horizontal position of the other AR lens 5. When the user needs to adjust the vertical position of the AR lens 5, press the first adjusting gear 901 toward the inside of the first adjusting box 2 to make the first adjusting gear 901 move upward. The wheel 901 contacts the first fixed rack 10, and at this time the limit gear 902 is disengaged from the second fixed rack 13, and then the first adjusting gear 901 is rotated to conveniently adjust the vertical height of the slider 8, and then conveniently adjust the vertical position of the AR lens 5 corresponding to the slider 8. After the AR lens 5 is adjusted to the required height, the first adjusting gear 901 is released, and the elastic potential energy accumulated in the spring of the first fixed box 11 is used to make the limit gear 902 contact with the second fixed rack 13 again. At this time, the first adjusting gear 901 is disengaged from the first fixed rack 10, and the limit gear 902 is in contact with the first telescopic rack 12 and the second fixed rack 13 at the same time, and is limited in the vertical direction, thereby conveniently realizing independent adjustment of the AR lens 5 in the vertical direction, so that the AR glasses can be comfortably used by different users.
