Detailed Description
In order that the above objects, features and advantages of embodiments of the utility model may be more clearly understood, a further description of aspects of embodiments of the utility model will be provided below. It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the utility model, but embodiments of the utility model may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the utility model.
Example 1
Referring to fig. 1 to 4, the present embodiment provides a lens structure including a first lens 1, a second lens 2, and two electromagnetic structures 3.
The first lens 1 and the second lens 2 are oppositely arranged, a filling liquid 6 is sealed between the first lens 1 and the second lens 2, the first lens 1 comprises a first soft lens body 11 and a first hard lens body 12 connected to the outer edge of the first soft lens body 11, and the second lens 2 comprises a second soft lens body 21 and a second hard lens body 22 connected to the outer edge of the second soft lens body 21.
One of the two electromagnetic structures 3 is connected with the first rigid mirror 12, the other of the two electromagnetic structures 3 is connected with the second rigid mirror 22, and the two electromagnetic structures 3 are used for respectively driving the first rigid mirror 12 and the second rigid mirror 22 to move towards a direction away from each other when being electrified so as to enable the first soft mirror 11 and the second soft mirror 21 to bulge towards a direction approaching each other under the action of the flow of the filling liquid 6 or driving the first rigid mirror 12 and the second rigid mirror 22 to move towards a direction approaching each other so as to enable the first soft mirror 11 and the second soft mirror 21 to bulge towards a direction away from each other under the action of the flow of the filling liquid 6.
In particular, referring to the left-right direction of the drawing sheet shown in fig. 1, the first lens 1 may be disposed at the left side of the second lens 2, the filling liquid 6 filled in the gap between the first lens 1 and the second lens 2 may occupy 30% -70% of the volume of the gap between the first lens 1 and the second lens 2, and air is strictly prevented from entering, so that the filling liquid 6 may flow in the gap.
In particular, the first lens 1 and the second lens 2 may each be a concave lens, so that they can be used for myopic users. Specifically, the relationship between the radian of the concave lens and the degree of the myopic lens of the lens is: myopic spectacles power = radian x100, radian = 1/f (f is focal length).
It follows that the larger the curvature of the concave lens, the larger the power of the endoscope, whereas the smaller the curvature of the concave lens, the smaller the power of the endoscope. Therefore, the degree of the lens structure can be adjusted by adjusting the radian of the lens structure, and the effect of adjustable degree of the myopia glasses is achieved.
Therefore, in the lens structure of this embodiment, two electromagnetic structures 3 are provided, and two electromagnetic results are respectively connected with the first hard lens body 12 and the second hard lens body 22, so that the first hard lens body 12 and the second hard lens body 22 can be driven to move to change the gap between the first lens 1 and the second lens 2 when being electrified, so that the filling liquid 6 in the gap flows to change the supporting force on the first soft lens body 11 and the second soft lens body 21, and further the radian of the first soft lens body 11 and the second soft lens body 21 is changed to realize the adjustable degree of the lens structure.
The specific adjustment process is as follows:
for example, when the radian of the lens structure needs to be increased to increase the degree of the lens structure, the two electromagnetic structures 3 can be electrified at this time, so that the two electromagnetic structures 3 respectively drive the first rigid lens body 12 and the second rigid lens body 22 to move towards a direction away from each other, so as to increase the gap between the first rigid lens body 12 and the second rigid lens body 22, further enable the filling liquid 6 filled in the gap between the first lens 1 and the second lens 2 to flow from the center to the outer edge, and the first soft lens body 11 and the second soft lens body 21 are softer, and along with the flowing process of the filling liquid 6 to the outer edge, the supporting effect of the filling liquid 6 on the first soft lens body 11 and the second soft lens body 21 is reduced, so that the first soft lens body 11 and the second soft lens body 21 are protruded towards a direction close to each other, and further increase the radian of the lens structure.
For another example, when the radian of the lens structure needs to be reduced to reduce the degree of the lens structure, the two electromagnetic structures 3 can be electrified at this time, so that the two electromagnetic structures 3 drive the first rigid lens body 12 and the second rigid lens body 22 to move towards the direction close to each other when electrified, thereby reducing the gap between the first rigid lens body 12 and the second rigid lens body 22, and further increasing the supporting effect of the filling liquid 6 on the first soft lens body 11 and the second soft lens body 21 in the process of flowing the filling liquid 6 from the outer edge to the center, so that the first soft lens body 11 and the second soft lens body 21 are protruded towards the direction far away from each other, and the radian of the first soft lens body 11 and the second soft lens body 21 is reduced, thereby reducing the degree of the lens structure.
The radian of the first lens 1 and the second lens 2 can be adjusted through the two processes, so that the degree of the lens structure can be adjusted, and the lens structures with different degrees do not need to be replaced again, so that the cost can be saved, and the waste is avoided.
Furthermore, the driving of the first rigid mirror 12 and the second rigid mirror 22 by the two electromagnetic structures 3 towards each other or towards each other can be achieved in particular by controlling the direction of the current that is coupled to the electromagnetic structures 3. For example, when the two electromagnetic structures 3 are subjected to forward current, the first rigid mirror 12 and the second rigid mirror 22 move toward each other at this time; when the two electromagnetic structures 3 are subjected to reverse currents, the first rigid mirror 12 and the second rigid mirror 22 move away from each other.
In addition, the adjustment of the different radians of the first lens 1 and the second lens 2 can be changed by controlling the moving stroke of the first rigid lens body 12 and the second rigid lens body 22 in the direction of approaching each other or the moving stroke of moving in the direction of moving away from each other by controlling the magnitude of the current supplied to the two electromagnetic structures 3.
Referring to fig. 1 and 2, in some embodiments, the thickness of the first soft lens body 11 gradually increases in a direction along the center of the first soft lens body 11 to the outer edge of the first soft lens body 11.
That is, by gradually increasing the thickness of the first soft lens body 11 from the center to the outer edge, the softness of the first soft lens body 11 is gradually reduced from the center to the outer edge, and then the deformability of the first soft lens body 11 is gradually reduced from the center to the outer edge, which is more advantageous for the first lens 1 to deform into a rounded concave lens.
Accordingly, the thickness of the second soft mirror 21 gradually increases in a direction along the center of the second soft mirror 21 to the outer edge of the second soft mirror 21.
That is, by gradually increasing the thickness of the second soft lens body 21 from the center to the outer edge, the softness of the second soft lens body 21 is gradually reduced from the center to the outer edge, and then the deformability of the second soft lens body 21 is gradually reduced from the center to the outer edge, which is more advantageous for the second lens 2 to deform into a rounded concave lens.
In particular, the first soft lens body 11 and the second soft lens body 21 may be made of soft materials, so that they are easily deformed to change the radians of the first lens 1 and the second lens 2. In addition, the first rigid lens body 12 and the second rigid lens body 22 can be made of transparent materials with harder textures.
Referring to fig. 2, in some embodiments, the gap between the first lens 1 and the second lens 2 increases gradually in a direction along the center of the first lens 1 to the outer edge of the first lens 1, thereby making it easier for the filling liquid 6 to flow from the center to the outer edge or from the outer edge to the center, thereby facilitating adjustment of the curvature of the lens structure, thereby adjusting the power of the lens structure.
Referring to fig. 1 and 2, in some embodiments, the lens structure further includes a connecting ring 4, the connecting ring 4 is at least sleeved on the outer edges of the first lens 1 and the second lens 2, and the connecting ring 4, the first lens 1 and the second lens 2 jointly enclose a sealing cavity for sealing the filling liquid 6, so that the filling liquid 6 can be filled in the sealing cavity in a sealing manner, and thus, during the process of moving along the direction that the first rigid lens body 12 and the second rigid lens body 22 approach to each other or move away from each other, the filling liquid 6 can flow from the center to the outer edge or from the outer edge to the center in the sealing cavity.
Referring to fig. 1 and 2, in some embodiments, one of the two electromagnetic structures 3 is located on a side of the first rigid body 12 away from the second rigid body 22, the other of the two electromagnetic structures 3 is located on a side of the second rigid body 22 away from the first rigid body 12, and the two electromagnetic structures 3 are symmetrically disposed.
Specifically, referring to the left-right direction of the drawing sheet shown in fig. 1, the first lens 1 is set to be located at the left side of the second lens 2, one of the two electromagnetic structures 3 is located at the left side of the first rigid lens body 12, the other of the two electromagnetic structures 3 is located at the right side of the second rigid lens body 22, and the two electromagnetic structures 3 can be symmetrically arranged, so that the two electromagnetic structures 3 can drive the first rigid lens body 12 and the second rigid lens body 22 to synchronously move.
Referring to fig. 1, in some embodiments, the electromagnetic structure 3 is an electromagnetic ring 31, and the electromagnetic ring 31 is used for electrically connecting with a control structure of the glasses, so that the first rigid lens body 12 or the second rigid lens body 22 can be driven to move under the control of the control structure.
Referring to fig. 2, in some embodiments, the electromagnetic ring 31 is sleeved in the connecting ring 4, that is, the outer diameter of the electromagnetic ring 31 may be equal to the inner diameter of the connecting ring 4 or slightly smaller than the inner diameter of the connecting ring 4, so that the electromagnetic ring 31 may be sleeved in the connecting ring 4, and the whole lens structure is more regular and beautiful.
In some embodiments, the light guiding rate of the filling liquid 6, the light guiding rate of the first soft lens body 11 and the light guiding rate of the second soft lens body 21 are the same, so as to ensure the normal use of the lens structure.
