Vision correcting eyeglasses of two-overlapped-lens-assembled horizontal type single-motor driving device

Abstract

The invention discloses a pair of viewsight correcting eyeglasses of a two-overlapped-lens-assembled horizontal type single-motor driving device, and belongs to the eyeglasses for slidable varifocal vision correction by electrically driving two parallel optical lenses. The eyeglasses comprise an eyeglass shell, and a lens driving device, a controller, a power supply and the like which are arrangedin the eyeglass shell. Two parallel protruding strips are arranged on a lower baffle of the eyeglass shell. A groove between the two parallel protruding strips is a lens clamping groove. The lens driving device comprises a speed reduction motor assembly fixed to an L-shaped support plate at one end of the upper face of a dual-pore strip-shaped plate. A lens group is clamped in the lens clamping groove. The overlapped lenses generate a large number of diopter combinations. A motor directly drives the two lens groups at equal speeds to move in opposite directions at equal speeds, the structureis simple, and the eyeglasses help nearsighted people to restore the eyesight as the eye varifocal training device.

Description

technical field [0001] The invention belongs to the technical field of zoom optical lenses, and in particular relates to vision correcting glasses with electrically driven two groups of parallel optical lenses with slidable variable focal length, overlapping double lenses and a horizontal single motor drive device. 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 corr...

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
