Description

Lens driving assembly of vision intensifier

Technical Field

The utility model relates to an eyesight correction and training instrument, especially an increase appearance lens drive assembly.

Background

With the progress of society, more and more people form the problems of myopia, amblyopia and the like due to various internal or external factors, and in order to solve the problems, the common solution is to use a series of correction devices to perform vision training so as to achieve the purpose of improving the naked eye vision. However, most of the vision rehabilitation training in the market at present needs to be carried out by special rehabilitation institutions, which directly influence the normal work and study of people and bring great inconvenience to daily life.

SUMMERY OF THE UTILITY MODEL

In order to overcome the deficiencies in the prior art, a health care device capable of realizing visual training is provided, the utility model relates to a sight enhancing instrument lens driving assembly.

The utility model discloses the concrete technical scheme who takes does: a lens driving assembly of a sight enhancing instrument comprises a support, a driving motor and a driving screw rod, wherein two ends of the support are provided with mounting parts bent upwards, the driving screw rod is correspondingly assembled on the mounting parts, and the driving motor is correspondingly connected to one end of the driving screw rod; the driving screw rod is correspondingly provided with a sliding block, a sliding rod penetrating through the sliding block is arranged between the mounting parts, and a lens is correspondingly connected below the sliding block; two sets of drive assembly install and constitute same lens group in same mounting panel both sides, and two lenses in same lens group are central symmetry, the lens of same lens group of drive assembly drive overlaps or staggers.

Preferably, the non-adjacent side surfaces of two lenses of the same lens group are non-horizontal curved surfaces with the mathematical change rule of height fluctuation, each non-horizontal curved surface comprises a highest point and a lowest point, a plurality of upper optical centers which are continuously changed are uniformly distributed between the highest point and the lowest point along the non-horizontal curved surfaces of the lenses, and the refractive powers of the plurality of upper optical centers are sequentially decreased or increased.

Preferably, two ends of one group of supports in the same lens group are fixedly connected on the mounting plate through adjusting bolts. And a reset spring which is abutted between the mounting plate and the support is sleeved outside the adjusting bolt.

The beneficial technical effects are as follows: drive the lens through driving motor and overlap or crisscross, can carry out the lens and zoom, set up adjusting bolt, can realize more focal length changes through adjusting the interval between two lenses.

figure 3 is a schematic of a lens curve.

In the figure, a bracket 1, a driving motor 2, a driving screw rod 3, a sliding rod 4, a sliding block 5, a lens 6, an adjusting bolt 7, a return spring 8 and a shell 9 are arranged.

Detailed Description

A vision intensifier lens 6 drive assembly, see fig. 1-3: the device comprises a bracket 1, a driving motor 2 and a driving screw rod 3, wherein two ends of the bracket 1 are provided with mounting parts which are bent upwards, the driving screw rod 3 is correspondingly assembled on the mounting parts, and the driving motor 2 is correspondingly connected to one end of the driving screw rod 3; the driving screw 3 is correspondingly provided with a sliding block 5, a sliding rod 4 penetrating through the sliding block 5 is arranged between the mounting parts, and a lens 6 is correspondingly connected below the sliding block 5; two sets of drive assembly install and constitute same lens 6 groups in same mounting panel both sides, and two lenses 6 in same lens 6 groups are central symmetry, drive assembly drive lens 6 in the same lens 6 group overlap or stagger.

Preferably, the non-adjacent side surfaces of the two lenses 6 in the same lens 6 group are non-horizontal curved surfaces with the mathematical change rule of height, the non-horizontal curved surfaces comprise a highest point and a lowest point, a plurality of upper optical centers which continuously change are uniformly distributed between the highest point and the lowest point along the non-horizontal curved surfaces of the lenses 6, and the refractive powers of the plurality of upper optical centers are sequentially decreased or increased.

Preferably, two ends of one group of brackets 1 in the same lens 6 group are fixedly connected on the mounting plate through adjusting bolts 7. And a return spring 8 which is abutted between the mounting plate and the support 1 is sleeved outside the adjusting bolt 7.

Drive lens 6 through driving motor 2 and overlap or crisscross, can carry out lens 6 and zoom, set up adjusting bolt 7, can realize more focal length changes through adjusting the interval between two lenses 6.

The highest point of the lens 6 is the maximum diopter center of far vision of the lens 6, the lowest point of the lens 6 is the maximum diopter center of near vision of the lens 6, an upper optical center is uniformly distributed between the highest point and the lowest point at an interval of 0.5mm, and the degree number of the upper optical center is sequentially decreased or increased progressively according to 0.50D; the degrees of the highest points in the same 6 groups of lenses are all +8.00D, and the degrees of the lowest points are all-15.00D. Through optimizing to the channel width and the refraction change gradient of lens 6, make it possess better field of vision width, this lens 6 still has better mechanical properties simultaneously, and the one side is the plane, and the one side is the curved surface to can make it move corresponding position through mechanical device very conveniently, in addition, form different dioptric number of degrees through the change of position and ensure to reach the vision training requirement under the condition of satisfying normal vision.

The stepping motor is a conventional commercially available product, and can be freely selected according to the requirement only by circuit connection.

Two sets of 6 sets of lenses are correspondingly installed in the shell 9, and the shell 9 is internally provided with a mounting plate corresponding to the driving assembly.
