Horizontal dual-motor driving device for vision correction overlapped lens double-eye uniform sliding

Abstract

The invention discloses a horizontal dual-motor driving device for vision correction overlapped lens double-eye uniform sliding, and belongs to a sliding variable focal length vision correction device for electrically driving two groups of parallel optical lenses. The device comprises two geared motor assemblies fixed on 'L'-shaped bracket plates at two ends above a double-hole strip plate, wherein two sliding lens assemblies are respectively arranged in two strip-shaped holes of the double-hole strip plate; the lens assemblies are sequentially connected with multiple vertical equidistance variable focal striped surface lenses, grooved bars connecting the lenses, a sliding base plate and a top clamping plate from bottom to top; two of the multiple vertical equidistance variable focal striped surface lenses connected in a grooved bar form a double-lens group; two geared motors respectively drive the two lens assemblies to slide relative to each other; two overlapped lenses produce lots of combined diopter. Therefore, the variable focal length eye training device in the invention is capable of helping a person suffering from nearsightedness to restore eyesight.

Description

technical field [0001] The invention belongs to the technical field of zoom optical lenses, and in particular relates to a sliding motor drive device for sliding two sets of parallel optical lenses to drive two groups of parallel optical lenses to zoom in and out for vision correction. Background technique [0002] Chinese patent 201610092191.8 "A Gradient 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 several regions are provided on the free-form surface, and each region are equal in vertical length. The length of the area is 0.1.0 mm to 100 mm, the diopters of the area are 1 to 2000 degrees, the diopters are evenly distributed on the lens, and the focal points are equally divided into each unit length. [0003] The defect of the above-mentioned "A Gradient Focus Lens" is that the "free-form surface" is used as a training lens for correcting myopia. It is difficult...

Problems solved by technology

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
