Description

Technical Field

[0001] The utility model relates to a glasses debugging device, in particular to an electric-assisted zoom glasses debugging device. Background Technique

[0002] The preparation of glasses includes: the determination of glasses power (visual acuity power), the selection of spectacle frames and lenses, the edge modification of lenses (involving the positioning and displacement of the lens center), and the assembly (adjustment of glasses), etc. Among them, the determination of visual acuity power is particularly important. The determination of visual acuity power needs to be determined through professional tests such as optometry.

[0003] Optometry usually completes the vision test through a comprehensive optometry instrument or a trial frame. When we perform optometry, whether it is a comprehensive optometry instrument or a trial frame, the power at a default vertex distance of 12 mm is assumed, and the user's vision is tested by changing the power of the trial lenses.

[0004] However, in the actual optometry process, there are differences between people in appearance or wearing glasses habits, which cause the actual vertex distance to exceed or fall below the default value, resulting in a deviation between the vision test result and the actual situation, affecting the subsequent vision correction of the eyes.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] Please refer to Figures 1 to 8 , as an embodiment of the present invention, the electric-assisted zoom glasses debugging device includes a box body 1 and a sample holder 103 fixedly installed on the box body 1; a plurality of groups of lens holders 7 are provided on the box body 1, and the lens degrees installed on each lens holder 7 show an increasing or decreasing trend;

[0042] An eyepiece opening 101 and an objective lens opening 102 are formed on the box body 1, and through the mutual cooperation of the eyepiece opening 101, the objective lens opening 102 and the lens, the sample on the sample holder 103 can be observed in the best focal length environment;

[0043] A motor 2 is fixedly installed on the box body 1, and a plurality of groups of zoom mechanisms are provided on the motor 2, and the zoom mechanisms can drive the lens holder 7 to move away from or close to the eyepiece opening 101;

[0044] A conversion mechanism is also provided on the motor 2, and when the current zoom mechanism drives the lens holder 7 cooperating with it to reach the end of the stroke, the motor 2 can drive the conversion mechanism to act to replace the zoom mechanism and the lens holder 7.

[0045] In this embodiment, during use, the human eye first observes the sample on the sample holder 103 through the eyepiece port 101, the objective lens port 102, and the lens with a diopter F0 mounted on the lens holder 7. Then, the motor 2 is started. Driven by the motor 2, the zoom mechanism operates to perform electric-assisted zooming. The zoom mechanism drives the lens holder 7 away from or closer to the eyepiece port 101, causing the lens to move away from or closer to the eyepiece port 101. By changing the eye-lens distance d (the distance between the inner vertex of the lens and the anterior corneal vertex of the eyeball), the most accurate field-of-view focal length is achieved.

[0046] If, when the current zoom mechanism drives the lens away from or closer to the eyepiece port 101 to reach the end of the stroke, the optimal focal length has still not been reached, the switching mechanism will act driven by the motor 2. The zoom mechanism and the lens holder 7 are replaced through the switching mechanism to replace the lens with a larger or smaller diopter F0 until it is possible to observe the sample at the optimal focal length.

[0047] Currently, during the vision test process, basically, different-diopter lenses are tried on to measure the user's vision diopter, and finally, the adjustment of the glasses diopter is completed. Generally, the diopters of the tried-on glasses are specific increasing or decreasing values, such as 50 degrees, 55 degrees, 60 degrees, 65 degrees, etc. When the user's actual vision diopter is 52 or 53 degrees, the measured result is either 50 degrees or 55 degrees; this is because the diopters of the tried-on glasses are distributed in a dot pattern within a certain range, rather than in a linear continuous distribution. In the present utility model, within a certain vision range, without changing the lens diopter, electric-assisted adjustment of the eye-lens distance is used to achieve zooming, and the user's actual vision diopter is deduced. Since the eye-lens distance can be adjusted within a continuous range, the measured vision diopter is more accurate.

[0048] Under the optimal focal length environment, through the effective diopter F S Formula: F S = F0 / (1 - dF0) to accurately confirm the actual diopter of the human eye.

[0049] As a further solution of the present utility model, a transmission shaft 3 is fixedly installed at the output end of the motor 2, and a half gear 4 is fixedly installed on the transmission shaft 3. When the motor 2 operates, the zoom mechanism is driven by the toothed part of the half gear 4; a driving wheel 8 is fixedly installed at one end of the transmission shaft 3 away from the motor 2. When the toothed part of the half gear 4 is disengaged from the zoom mechanism, when the motor 2 operates, the switching mechanism is driven by the driving wheel 8.

[0050] In this embodiment, when the motor 2 operates, it drives the transmission shaft 3 to rotate, thereby driving the half gear 4 and the driving wheel 8 to rotate. The current zoom mechanism starts to act under the drive of the toothed part of the half gear 4 to adjust the eye-to-lens distance d. When the lens with degree F0 on the current lens holder 7 moves to the end of the stroke and still does not reach the optimal focal length environment, a lens with a larger or smaller degree F0 needs to be replaced. At this time, the toothed part of the half gear 4 just disengages from the zoom mechanism.

[0051] The driving wheel 8 drives the conversion mechanism to act only after the toothed part of the half gear 4 disengages from the zoom mechanism.

[0052] As a further solution of the present invention, the conversion mechanism includes a panel 10 rotatably installed on the box body 1. The panel 10 is fixedly installed with a driven wheel 9. Four groups of third notches 901 are formed on the driven wheel 9, and the four groups of third notches 901 are distributed in a cross shape;

[0053] The driving wheel 8 includes a boss 801 that cooperates with the driven wheel 9 and a second protruding block 802 that slidably cooperates with the third notch 901.

[0054] In this embodiment, the second protruding block 802 rotates around the axis of the transmission shaft 3 under the drive of the driving wheel 8. When the toothed part of the half gear 4 cooperates with the zoom mechanism, there is no cooperation between the second protruding block 802 and the third notch 901.

[0055] After the toothed part of the half gear 4 disengages from the zoom mechanism, the second protruding block 802 does not cooperate with the third notch 901 first. After rotating a certain buffer distance, the second protruding block 802 enters a third notch 901. At this time, the driving wheel 8 and the driven wheel 9 form a Maltese cross movement component. That is, while the second protruding block 802 slides in the third notch 901, its tangential force will drive the driven wheel 9 to rotate 90° through the cooperating third notch 901. Subsequently, the second protruding block 802 disengages from the cooperating third notch 901. This process completes the replacement of the zoom mechanism and the lens holder 7. After rotating a certain buffer distance, the toothed part of the half gear 4 cooperates with the replaced zoom mechanism.

[0056] As a further solution of the present invention, an arc-shaped notch 803 is formed on the boss 801. The radius of the arc-shaped notch 803 is the same as the radius of the driven wheel 9; four arc-shaped concave surfaces 902 are evenly distributed in a circle on the driven wheel 9, and the radius of the arc-shaped concave surfaces 902 is the same as the radius of the boss 801; the second protruding block 802 is located on the connecting line between the vertex and the center of the arc of the arc-shaped notch 803.

[0057] In this embodiment, when the toothed part of the half gear 4 is disengaged from the zoom mechanism, the side of the driven wheel 9 starts to enter the arc-shaped notch 803. When the center of the arc of the arc-shaped notch 803 and the center of the driven wheel 9 are on the same horizontal plane, the driven wheel 9 abuts against the arc-shaped notch 803.

[0058] When the toothed part of the half gear 4 is engaged with the zoom mechanism, the convex platform 801 abuts against the arc-shaped concave surface 902. At this time, the driven wheel 9 is restricted by the convex platform 801 and cannot rotate, making the cooperation between the zoom mechanism and the toothed part of the half gear 4 more stable.

[0059] As a further solution of the present utility model, the zoom mechanism includes a rotating sleeve 5 rotatably mounted on the panel 10. A full gear 501 is fixedly mounted at one end of the rotating sleeve 5 away from the panel 10. The full gear 501 meshes with the toothed part of the half gear 4; a through first notch 502 is formed in the rotating sleeve 5;

[0060] A fixed sleeve 6 is fixedly mounted on the panel 10, and the fixed sleeve 6 is arranged inside the rotating sleeve 5 and is in rotational cooperation therewith; a second notch 601 is formed in the fixed sleeve 6;

[0061] The zoom mechanism further includes a first protruding block 702 fixedly mounted on the lens holder 7. The first protruding block 702 passes through the first notch 502 and the second notch 601.

[0062] In this embodiment, the number of teeth of the full gear 501 is the same as that of the half gear 4, and the size is half of the size of the half gear 4, that is, during the meshing process of the toothed part of the half gear 4 and the full gear 501, the full gear 501 rotates one circle.

[0063] The first notch 502 is an inclined notch. The second notch 601 is a straight notch.

[0064] When the full gear 501 meshes with the half gear 4 and rotates, it drives the rotating sleeve 5 to rotate, and the first notch 502 also rotates accordingly. At the same time, the tangential force of the rotation of the first notch 502 pushes the first protruding block 702 to slide through its inclined inner wall. Due to the restriction of the second notch 601 on the first protruding block 702, the first protruding block 702 slides away from or close to the eyepiece port 101 on the second notch 601 under the push of the first notch 502, thereby driving the lens on the lens holder 7 to move away from or close to the eyepiece port 101 to change the eye relief d.

[0065] As a further solution of the present utility model, four fixing blocks 701 are fixedly arranged on the lens holder 7 at equal circumferential intervals. The fixing blocks 701 are in sliding contact with the inner wall of the fixed sleeve 6, and the length of the fixing blocks 701 is greater than the radius of the lens holder 7.

[0066] In this embodiment, the lens holder 7 moves away from or closer to the eyepiece port 101 driven by the first protruding block 702. During this process, the fixing block 701 slides against the inner wall of the fixing sleeve 6. Also, since the length of the fixing block 701 is greater than the radius of the lens holder 7, the lens holder 7 is more stable during sliding, and the lens can be stably fixed on the lens holder 7.

[0067] As a further solution of the present utility model, an eye mask is fixedly installed on the eyepiece port 101. The material of the eye mask is soft rubber and is in a curved surface shape.

[0068] In this embodiment, during use, the eye mask can cover other light sources in the room, making the detection result more accurate. At the same time, the soft rubber material improves the comfort during use.

[0069] As a further solution of the present utility model, a support plate and a forehead plate are fixedly installed on one side of the eyepiece port 101 on the box body 1. The support plate is located directly below the eyepiece port 101; the forehead plate is located directly above the eyepiece port 101.

[0070] In this embodiment, during use, the support plate is used to support the chin, making the detection process easier. The design of the forehead plate is beneficial to making the distance between the human eye and the lens more accurate, avoiding affecting the detection accuracy due to incorrect position of the human eye.

[0071] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
