Horizontal single-motor driving device for eyesight rectification overlapped lens group sliding

Abstract

The invention provides a horizontal single-motor driving device for eyesight rectification overlapped lens group sliding, belonging to a device electrically driving the two groups of parallel optical lenses to perform slidable focal length variation eyesight rectification. The horizontal single-motor driving device includes a deceleration motor assembly fixed on an L-shaped support plate at one end on a double-hole strip-shaped plate, two slidable lens assemblies are respectively arranged in the two strip-shaped holes of the double-hole strip-shaped plate, each lens assembly includes lenses with multiple vertical equidistant focal length variation striped surfaces, a grooved strip connecting the lenses, a slide substrate, a top clamp plate that are connected successively and mutually from the bottom to the top, the two lenses with multiple vertical equidistant focal length variation striped surfaces connected in the grooved strip form a double-lens group, the deceleration motor enable the two lens assemblies to slide in the opposite directions through the engaging gears at the two sides, and the overlapped two lenses generate a lot of combined diopter. A motor is additionally provided with a gear, so that the two double-lens groups can be driven to perform the constant speed movement in the opposite directions at the constant speed. The focal length variation training device is helpful in storing myopia vision.

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
