Description
Technical Field
The utility model belongs to the technical field of zoom optical lens, especially, relate to with the variable focal length of two sets of parallel optical lens slidingtypes of electric drive, have the vertical single motor drive arrangement's of overlapping double lens matched stack vision correction glasses.
Background
Chinese patent 201610092191.8 "a progressive focal lens" provides a lens with a flat bottom surface and a free-form surface on the other side, where the free-form surface is composed of concave surfaces, and the free-form surface is provided with a plurality of regions, and the vertical length of each region is equal. The length of the area is 0.1.0 mm-100 mm, the refractive power of the area is 1-2000 degrees, the refractive power is uniformly distributed on the lens, and each unit length is equally distributed with focuses.
The 'one kind of gradually-changed focus lens' has the defect that a 'free-form surface' is used as a lens for training for correcting myopia, and a regular training method matched with the 'free-form surface' is difficult to set, and the 'free-form surface' lens can only be used as a lens for training by a trained person to manually move the relative positions of two lenses. The shape structure of the 'plurality of areas' is not indicated by the 'free-form surface' lens, and the shape structure of the 'plurality of areas' is not known to be a spherical surface, an elliptic spherical surface or a trapezoidal surface; the diopter number in the length area of 0.1.0mm to 100mm is 1 to 2000 degrees, that is, the diopter number in the length area of 0.1.0mm to 100mm cannot be changed in the range of 1 to 2000 degrees, and it is not specified what the structure for realizing the diopter number in the length area of 0.1.0mm to 100mm is. Therefore, the technical scheme cannot realize the correction effect.
The chinese patent 201520246792.0 "a random variable focus lens set" provides one of: one surface of each lens is a horizontal plane, and the other surface of each lens is a non-horizontal curved surface which is up-and-down according with the mathematical change rule; the non-horizontal curved surfaces of the lenses are provided with a highest point and a lowest point; a plurality of continuously-changed optical centers are uniformly distributed between the highest point and the lowest point of the non-horizontal curved surface of the lens along the non-horizontal curved surface of the lens; the refractive powers of the plurality of optical centers are sequentially decreased or increased. The drawback is that the "compliance with mathematical variation rules" does not indicate what rules are. The optical centers are uniformly distributed at intervals of 1.0mm, the curved surface can only be a spherical structure by one optical center, the spherical structure is difficult to realize the training function of vision correction, the sight line of human eyes passes through the lens at one point, each interval in the lens is an optical center point, and the sight line point and the optical center point are difficult to coincide. Therefore, the technical scheme can not realize the training of vision correction and can not thoroughly solve the problems of visual fatigue and the like. And the description of "non-horizontal curved surface" does not indicate what curved surface is.
Chinese patent 201310311306.4 "a novel orthokeratology lens and method of use thereof" discloses that four arc rings with different curvatures are arranged at different diameter positions on a lens, so that the four arc rings with different curvatures can be obtained to treat the diseased eye by wearing one lens. The disadvantages are that: only four arc-shaped rings with different curvatures are arranged on one pair of glasses, the number of curvature lenses which can be selected for treating the eyes with diseases by wearing one pair of glasses is too small, the most suitable glasses are selected only in a family with a large number of spare glasses, and the treatment is not convenient and influenced; too many glasses to choose from and the cost increases.
Chinese patent 201521122053.7 "a zoom glasses" discloses glasses in which two zoom lenses are respectively provided for the left and right eyes to be zoomed by an electric motor, so as to treat the eyes. The disadvantages are that:
(1) the purpose of the invention can not be realized: the patent only discloses a transmission mechanism, and does not disclose the structure of a zoom lens, so that how to facilitate the transmission mechanism to realize zooming is unclear, namely, 201521122053.7 'a zoom glasses' transmission mechanism is matched with 201310311306.4 'a novel orthokeratology lens and a using method thereof' spectacle lens, and 201521122053.7 'a zoom glasses' can not realize zooming application of 'vision training';
(2) the transmission structure is wrong: the transmission order of the structure is that the motor, the reduction gear box, the positive and negative tooth screw rods, the fixing bolt, the front lens and the rear lens slide in opposite directions. The common knowledge "positive and negative teeth screw" is not that one screw has positive teeth and negative teeth, that is, one screw only has either positive teeth or negative teeth. Therefore, the common knowledge is: one screw can only drive the direct engaging part to rotate in one direction at the same time. The 201310311306.4 patent is a wrong configuration in which a screw simultaneously drives two direct engagement member "anchor bolts" in opposite directions, thereby sliding the front and rear lenses in opposite directions.
(3) The "fixing bolt" cannot realize transmission: as can be seen from the text and drawings of the patent document, the "fixing bolt" is an intermediate member for driving the "forward and reverse threaded rod" and the "lens", but the text and drawings of the patent document do not provide a structure in which the "fixing bolt" can drive the "forward and reverse threaded rod" and the "lens". Only the position relation of each part and no structure relation exist, and the transmission structure required by the invention cannot be realized.

That is, the remote controller sends out the synthetic focal length value of two double lens sets 116, and the synthetic focal length value of two double lens sets 116 at the specified position of the remote controller of the glasses of the utility model is the same. Because the two dual lens groups 116 are limited by the two parallel ribs 214 of the lower baffle 212 of the frame main shell 206 to move only in parallel, the gap distance between the two dual lens groups 116 cannot be changed, and the two dual lens groups 116 are fixed by the ribs 214, the two dual lens groups 116 slide to the same position at different times, and the resultant focal length of the two dual lens groups 116 is the same. This solves the problem that the parameter requirement of remote command control is consistent with the actual combined focal length value of the two dual-lens sets 116, i.e. the requirement of remote control can be accurately realized. In addition, the ribs 214 also prevent the lens driving device 202 from shifting within the frame main housing 206 when the eyeglasses are accidentally dropped on the ground, especially the two dual-lens sets 116 from being broken, because the ribs 214 limit the damaging action of the two dual-lens sets 116 vibrating sideways when dropped.
The effect of the glasses is as follows:

Each vertical rack plate 113 is fixedly connected with a plurality of vertically equidistant zoom striated surface lenses 222 of the lens assembly 104, so that the two vertical rack plates 113 slide in opposite directions at a constant speed to drive the plurality of vertically equidistant zoom striated surface lenses 222 of the two lens assemblies 104 to slide in opposite directions at a constant speed. Therefore, when the plurality of strip-shaped curved surfaces 3 with equal widths on the plurality of vertically equidistant zooming striated surface lenses 222 of the two lens assemblies 104 slide to any different positions, different diopters synthesized by the two plurality of vertically equidistant zooming striated surface lenses 222 can be obtained.
Since the strip widths d of each of the side-by-side equidistant width strip-shaped curved surfaces 3 are equal, and each of the strip widths d ranges from 0.5mm to 3.0mm by a certain value. If the width of one of the plurality of vertically equidistant zoom striated surface lenses 222 is 40mm, the range of each stripe width d is 1.0mm, and each of the plurality of vertically equidistant zoom striated surface lenses 222 has 40 equidistant width stripe curved surfaces 3. The two vertically equidistant varifocal striped surface lenses 222 of the two lens assemblies 104 slide relative to each other to change the relative positions, and 40 × 40 to 1600 different diopters can be obtained. In the prior art, Chinese patent 201310311306.4 entitled "novel orthokeratology lens and method for using the same" discloses a lens with four arc rings of different curvatures, i.e. four different diopters. It can be seen that the device of this patent produces a pair of spectacles of 1600 different diopters, increased by a 400-fold amount of diopters over the four diopters of a pair of prior art spectacles. The device has the advantages that the device has the significance in using, the zoom training of the eyes is realized, the eyesight of a patient with myopia is helped to be recovered, the requirement of the patient on all diopters for recovering the eyesight can be met by one pair of glasses made by the device, and the problems that in the prior art, the patient is required to be difficult to correctly select different glasses, the treatment can be carried out only at home, and the glasses cost is high are solved.
The gear motor 102 is fixedly connected to the center position of the upper surface of the double-hole strip-shaped plate 101, the gear 117 on the rotating shaft of the gear motor 102 is directly meshed with the vertical rack plates 113 of the two lens assemblies 104, the power transmission of the gear motor 102 for synchronously driving the two lens assemblies 104 is simpler, the power loss in the transmission is reduced, and the reduction of the transmission consumption is very important particularly for a miniature light motor with small power used on glasses.
The utility model has the advantages as follows:
1. the doctor can remotely control the training of the patient who recovers the eyesight: the lens diopter numerical value range N of each strip-shaped curved surface with equal distance width in the same lens ruled grain single sheet is the same, the significance lies in that when a computer program is used for controlling a motor to drive the front and the rear lens ruled grain single sheets to displace, the displacement speed and the synthetic lens diopter numerical value of the two strip-shaped curved surfaces with equal distance width at each position of the two ruled grain single sheets have a fixed functional relation, namely the synthetic lens diopter numerical value at each position can be controlled by the displacement speed between the two single sheets, the rotation speed and the rotation angle of the motor can be controlled by a computer through a network remote control mode, the synthetic lens diopter numerical value of the front and the rear single sheets can be controlled, and a doctor can train.
2. Any position of the front and rear lenses can simultaneously produce the accurate synthetic lens diopter: each strip width d in the straight grain single sheets is the same, when two straight grain single sheet synthetic lenses are used, one strip-shaped curved surface with the equal distance width can be combined into one synthetic lens with the set diopter value, and other strip-shaped curved surfaces with the equal distance width in the two straight grain single sheets can also be respectively combined into the synthetic lens with the set diopter value, so that an area which cannot be imaged is not generated.
3. Any overlapping position of the front and rear lenses can simultaneously produce a plurality of synthetic lens powers for the patient to choose from: the structure form of each strip-shaped curved surface with equal distance width in the same lens straight-line single chip is that each strip-shaped curved surface with equal distance width is provided with a lens focus connecting line, each single chip is provided with a plurality of lens focus connecting lines which are parallel to each other, when the front and the rear cooperative lenses slide to change positions, the sight line of a patient passes through the points of the front and the rear single chips to always find the synthetic lens diopter which is most suitable for the eyes of the patient, and the multiple gradient synthetic lens diopters which are most suitable for the positions adjacent to the synthetic lens diopters are used for zooming training of the eyes, so that the vision recovery of the patient with myopia can be facilitated. The utility model discloses a glasses can obtain 1000 multiple gradient synthetic lens diopters, is obviously superior to prior art glasses and can only obtain 4 kinds of gradient synthetic lens diopters.
Use the utility model discloses the glasses of making, preceding, the mutual relative slip of back lens can produce the combined lens diopter effect of 1000 a plurality of differences, and these a large amount of, slidable and the combined lens diopter that changes are to the training of zooming of eyes, help the patient of myopia to resume visual good method.
4. The smooth surfaces of the front and the rear lenses are contacted to form an overlapped gapless structure so as to ensure the accuracy of the refractive power of the synthesized lens: two parallel strip holes of the double-hole strip plate limit the front and back lenses to reciprocate along the long edge direction of the strip holes and do not keep the direction to separate the front and back lenses from the gap.
5. The motor gear directly engages with the vertical rack plates fixed on the front and rear lenses respectively, so that the sliding speeds and lengths of the front and rear lenses in opposite directions are completely synchronous.
6. The detachable branch structure of the sliding base plate and the vertical rack plate enables the sliding base plate and the vertical rack plate to be clamped into the strip-shaped holes of the double-hole strip-shaped plate in a thinner mode, and then the distance between the sliding base plate and the vertical rack plate is adjusted, so that the final total thickness of the sliding base plate and the vertical rack plate is small in gap in the strip-shaped holes, and the sliding tight fit clamping structure is provided.
7. One motor and one gear can directly drive the two double-lens groups to move at a constant speed in opposite directions at a constant speed, and the structure is simple.
8. The motion of two lens groups has been injectd by the sand grip of two parallels of picture frame owner shell baffle down can only mutual parallel motion, can not change the crack clearance distance between two lens groups, and the sand grip makes to be the fixed unchangeable crack clearance distance between two lens groups, then two lens groups slide to same unit at different time, and the synthetic focus value of its two lens groups is the same. The problem that the parameter requirement of remote command control is consistent with the actual combined focal length value of the two double-lens groups is solved, and the requirement of remote control can be accurately realized. In addition, the raised lines also avoid the problem that the glasses are accidentally fallen to the ground to cause the lens driving device to shift in the main shell of the glasses frame, and particularly two double-lens groups are broken, because the raised lines limit the destructive action of the two double-lens groups which vibrate to the side surface when the two double-lens groups are fallen.
