The disadvantage is that one spectacles has only four arc rings with different curvatures, and the number of optional curvature mirrors for treating sick eyes is too small when wearing one such spectacles. It is very inconvenient to have spare glasses at home, which will affect the treatment; too many glasses for selection will increase the cost
[0007]
(1) Unable to achieve the purpose of the invention: this patent only discloses the transmission mechanism, and does not disclose the structure of the "zoom lens", so it is not clear how the lens uses the transmission mechanism and how to achieve zooming. Spectacle lenses in 201310311306.4 "A New Orthokeratology Lens and Its Application Method", and 201521122053.7 "A Zoom Glasses" cannot realize the zoom application of "vision training";
[0008]
(2) The transmission structure is wrong: the transmission order of the structure is motor-reduction gearbox-positive and negative screw-fixing bolt-front lens and rear lens slide in opposite directions
[0009]
(3) The "fixing bolt" cannot realize the transmission: From the text and drawings of the patent document, it can be known that the "fixing bolt" is an intermediate component that transmits the "positive and negative screw" and the "lens", but the text and attached drawings of the patent document The figure does not provide the structure that the "fixing bolt" can drive the "positive and negative screw" and the "lens"
Only the positional relationship of each component, no structural relationship, can not achieve the transmission structure required to achieve the purpose of the invention

Embodiment 1
[0045] Embodiment 1. Vertical single-motor driving device for sliding of overlapping double lens groups for vision correction
[0046] Such as figure 1 , 2 , 3, 4, 5,
[0047] The vertical single-motor drive device for the sliding of the overlapping double lens group for vision correction includes a double-hole strip plate 101, a geared motor 102 fixed on the double-hole strip plate 101, and two of the double-hole strip plate 101 Two lens assemblies 104 that are slidingly connected are respectively provided in the strip holes 103;
[0048] The structure of the double-hole strip plate 101: a strip plate is provided with two parallel strip holes 103, the strip holes 103 divide the strip plate into an outer plate 106, a middle partition 107, and an inner plate 108; A center partition recess or a center partition hole 118 is provided on the upper center of the center partition 107;
[0049] The structure of the lens assembly 104: there are a plurality of vertical equidistant zoom stripe ...
Embodiment 2
[0069] Embodiment 2. Vertical single-motor driving device for sliding of overlapping double lens groups for vision correction
[0070] Such as figure 1 , 2 , 3, 4, 5, according to the structure of the above embodiment 1, only all the equidistant width strip curved surfaces 3 of the lens are different,
[0071] The side-by-side arrangement structure of all the strip-shaped curved surfaces 3 of a plurality of vertical equidistant zoom stripe lens 2 with equal distances is as follows:
[0072] A plurality of vertical equidistant zoom stripe lens 2 has all the equal distance width strip curved surface 3 lens diopter value N the same, the specific arrangement distribution of the lens diopter value from 200 degrees to -800 is as follows:

Abstract
The invention relates to a vertical single motor driving device for sliding an overlapped double lens set for correcting vision and belongs to a device for electrically driving two sets of parallel optical lenses to correct vision in the manner of sliding zooming. The vertical single motor driving device comprises a gear motor and a gear of the gear motor fixed in the middle on a double-hole bar-shaped plate; two lens assemblies in sliding connection are arranged in each of two bar-shaped holes of the double-hole bar-shaped plate; the lens assemblies structurally comprises a plurality of vertical equidistant zooming stripe plane lenses, slot-shaped bars for connecting the lenses, a sliding base plate and a top clamping plate which are sequentially connected with each other from bottom to top; two vertical equidistant zooming stripe plane lenses in one slot-shaped bar form a double lens set; the gear of the gear motor can drive the two lens assemblies to slide along opposite directions; the overlapped lenses can generate a large amount of combined diopter. One motor and one gear can directly drive the two lens sets to move at constant speed along opposite directions; the structure is simple; as an eye zooming training device, the device can help patients with myopic eye to recover vision.
Description
Technical field [0001] The invention belongs to the technical field of zoom optical lenses, and particularly relates to a sliding motor drive device for driving two sets of parallel optical lenses to be slidable and used for vision correction. Background technique [0002] Chinese Patent 201610092191.8 "A Gradual Focus Lens" provides a lens with a flat bottom surface and a free-form surface on the other side. The free-form surface is composed of concave surfaces, and there are several areas on the free-form surface, and each area The vertical lengths are equal. The length of the region is 0.1.0mm-100mm, the refractive power of the region is 1-2000 degrees, the refractive power is evenly distributed on the lens, and the focal points are equally distributed for each unit length. [0003] The defect of the above-mentioned "a progressive focus lens" is that the "free-form surface" is used as a training lens to correct myopia. It is difficult to set a regular training method that match...
