[0002] Smart glasses can automatically adjust the focal length of the lens according to the needs, so that users can get clear images in any situation, just like camera lenses can automatically adjust the focus. Existing smart zoom glasses are generally equipped with motors, zoom drive mechanisms, lenses and other components, and the automatic adjustment of the lenses is achieved through the cooperation of these components.

[0003] Most existing smart glasses with zoom lenses are controlled by micro DC motors to automatically adjust the focal length between the lens and the human eye. However, during adjustment, the lens moves at a speed that makes it difficult for the user to focus at the appropriate focal length, and multiple adjustments are often required, resulting in the user being unable to accurately adjust to the appropriate focal length.

DETAILED DESCRIPTION

[0023] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0025] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0026] See also Figures 1 to 6 In an embodiment of the utility model, a focusing reducer for intelligent electronic zoom glasses includes a glasses frame 1, a lens assembly 2, a threaded pusher, a speed regulating mechanism and a moving part.

[0027] The details are as follows, including:

[0028] See also Figure 2 , Figure 4, a spectacle frame 1, wherein a lens assembly 2 is symmetrically arranged on the spectacle frame 1, wherein the lens assembly 2 includes two lenses parallel to each other, one of which is movable relative to the spectacle frame 1, and also includes a threaded pusher installed in the spectacle frame 1;

[0029] A speed regulating mechanism is installed in the eyeglass frame 1, and the speed regulating mechanism includes a first transmission member and a second transmission member, wherein the first transmission member is connected to the threaded pushing member, and when the threaded pushing member is working, the gap between the first transmission members can be pushed to increase, so as to change the transmission ratio between the first transmission member and the second transmission member;

[0030] The symmetrically arranged moving parts are installed in the eyeglass frame 1 and connect the second transmission part and one of the lenses.

[0031] Of course, the threaded pusher is also connected to a driving member installed in the eyeglass frame 1. The driving member can be a micro motor. The threaded pusher is driven by the provided micro motor to work. The micro motor is connected to a control unit. The control unit controls the micro motor to rotate a certain angle and then stop automatically. When the micro motor needs to rotate a second time, the control unit needs to be controlled again. The control unit includes but is not limited to a control button and an integrated circuit board installed on the eyeglass frame 1. The method of controlling the micro motor belongs to conventional design, and this embodiment does not make specific limitations on this.

[0032] In detail, in this embodiment, the focusing reducer of the intelligent electronic zoom glasses described in the utility model is adopted. When in use, the threaded pushing member is controlled to work, driving the first transmission member itself to rotate while the gap between the first transmission members increases to change the transmission ratio between the first transmission member and the second transmission member. When the second transmission member rotates, it drives the moving member to work to drive one of the lenses to move relative to the glasses frame 1, and the distance between the two lenses changes. While the distance between the two lenses is automatically adjusted, the speed of adjusting the focal length of the glasses gradually slows down to ensure that the user can adjust to a focal length that suits the glasses.

[0033] See also Figure 4 The threaded pusher includes a bidirectional screw rod 15, which is rotatably installed in the eyeglass frame 1. A threaded sleeve 9 is threadedly connected to the bidirectional screw rod 15. The threaded sleeve 9 is slidably arranged in the eyeglass frame 1. A receiving plate 10 is fixedly connected to the threaded sleeve 9, and the receiving plate 10 is rotatably connected to the first transmission member.

[0034] The first transmission member includes a driving shaft 3, which is rotatably mounted in the eyeglass frame 1. The driving shaft 3 is rotatably connected to the bidirectional screw 15 via a belt 8. A first transmission wheel 4 is symmetrically arranged along the axial direction of the driving shaft 3. The first transmission wheel 4 is movably mounted on the driving shaft 3, and the first transmission wheel 4 is rotatably connected to the receiving plate 10.

[0035] Preferably, at least one group of strip limiting grooves 301 are symmetrically arranged on the driving shaft 3, and a strip limiting slider 401 that slides with the strip limiting grooves 301 is formed on the first transmission wheel 4. When the first transmission wheel 4 moves, the strip limiting slider 401 is driven to move synchronously. Under the cooperation of the strip limiting grooves 301 and the strip limiting slider 401, the first transmission wheel 4 is slidably connected with the driving shaft 3, and when the driving shaft 3 rotates, it can drive the first transmission wheel 4 to rotate synchronously.

[0036] The second transmission member includes a transmission shaft 7, which is rotatably installed in the eyeglass frame 1. A second transmission wheel 6 is symmetrically arranged along the axial direction of the transmission shaft 7. The second transmission wheel 6 is fixedly installed on the transmission shaft 7. The first transmission wheel 4 is rotatably connected to the second transmission wheel 6 via a transmission belt 5.

[0037] To elaborate, the switch is started to control the rotation of the above-mentioned two-way screw 15. When the two-way screw 15 rotates, it drives the threaded sleeve 9 to make a linear motion along the axial direction of the two-way screw 15. When the threaded sleeve 9 moves, it drives the receiving plate 10 to follow the movement. The receiving plate 10 drives the first transmission wheel 4 to move relative to the driving shaft 3. At this time, when the two-way screw 15 rotates, it drives the driving shaft 3 to rotate through the belt 8. When the driving shaft 3 rotates, it drives the first transmission wheel 4 to rotate synchronously, so that when the receiving plate 10 drives the first transmission wheel 4 to move, the first transmission wheel 4 rotates relative to the receiving plate 10, so that the two first transmission wheels 4 move away from each other, so that the conveyor belt 5 is affected by the first transmission wheel 4, and the transmission ratio between the first transmission wheel 4 and the second transmission wheel 6 increases, so that the rotation speed of the transmission shaft 7 is gradually slowed down to control the speed at which one of the lenses moves relative to the eyeglass frame 1.

[0038] See also Figure 5 Abutment surfaces arranged in an inclined structure are formed on the first transmission wheel 4 and the second transmission wheel 6 , and the radius of the first transmission wheel 4 is smaller than the radius of the second transmission wheel 6 .

[0039] The conveyor belt 5 is formed with a cross section that abuts against the first transmission wheel 4 and the second transmission wheel 6 , and the cross section is arranged in an isosceles trapezoidal structure.

[0040] Furthermore, when the above-mentioned conveyor belt 5 abuts against the first transmission wheel 4 and the second transmission wheel 6 respectively, the axial distance between the conveyor belt 5 and the first transmission wheel 4 is at a maximum value, and the axial distance between the conveyor belt 5 and the second transmission wheel 6 is at a minimum value. At this time, the transmission ratio between the first transmission wheel 4 and the second transmission wheel 6 is at a maximum value. When the two first transmission wheels 4 move away from each other, the gap between the first transmission wheels 4 increases. At this time, the conveyor belt 5 moves, and the axial distance between the conveyor belt 5 and the first transmission wheel 4 gradually decreases. In order to ensure the normal rotation of the conveyor belt 5, the abutting part with the second transmission wheel 6 also changes, and the axial distance between the conveyor belt 5 and the second transmission wheel 6 increases cylindrically, so that the conveyor belt 5 is always in a taut state. The transmission ratio between the first transmission wheel 4 and the second transmission wheel 6 is always changing, so that the rotation speed of the transmission shaft 7 gradually slows down.

[0041] See also Figure 6 The movable part includes a cylindrical part 12, which is rotatably installed in the eyeglass frame 1. The two sections of the transmission shaft 7 are rotatably connected to the two groups of the cylindrical parts 12 through a bevel gear set 11 respectively. A threaded groove is formed on the cylindrical part 12, and a sleeve 13 is slidably provided on the cylindrical part 12. A ball 14 that slides with the threaded groove is movably provided on the inner ring of the sleeve 13, and the sleeve 13 is detachably connected to one of the lenses.

[0042] When the transmission shaft 7 rotates, the two ends of the transmission shaft 7 respectively drive the two groups of columnar members 12 to rotate through the bevel gear set 11. When the columnar member 12 rotates, the thread groove thereon rotates synchronously. When the thread groove rotates, the ball 14 is squeezed. The sleeve 13 cannot rotate due to the restriction of the eyeglass frame 1, so that when the columnar member 12 rotates, the sleeve 13 moves linearly along the axial direction of the columnar member 12. When the sleeve 13 moves, it drives one of the lenses to move relative to the eyeglass frame 1, and the focal length is adjusted by changing the distance between the two lenses. The moving speed of one of the lenses gradually slows down to ensure that the user can adjust to a focal length suitable for the glasses.
