the base 100 and the movable seat 200 are oppositely arranged and have a gap;

the light conversion element 300 is fixedly arranged on the movable seat 200;

a plurality of deformable members 400 fixedly arranged between the base 100 and the movable seat 200, wherein the deformable members 400 comprise two first deformable members 401 arranged along a first axis P1 and two second deformable members 402 arranged along a second axis P2, the first axis P1 and the second axis P2 are both positioned on a plane connecting the base 100 and the deformable members 400, and the first axis 41 intersects the second axis 42; wherein, the deformable part 400 is an electro-deformable part and/or a temperature-controlled deformable part;

and a control module (not shown) electrically connected to the deformable member 400, the control module being configured to convert the jitter parameter into a current that is transmitted to the deformable member 400, so as to cause a deformation difference of the at least two first deformable members 401, thereby driving the movable seat 200 to rotate around a direction perpendicular to the first axis P1, and/or cause a deformation difference of the at least two second deformable members 402, thereby driving the movable seat 200 to rotate around a direction perpendicular to the second axis P2.

The base 100 is a fixed base of the whole reflection module, the movable base 200 is a bearing carrier of the light conversion element 300, and the light conversion element 300 is fixedly mounted on the movable base 200 and moves along with the movable base 200, so that the displacement of the light conversion element 300 can be adjusted while the displacement of the movable base 200 is adjusted, and the displacement deviation generated when the reflection module shakes is compensated through the displacement adjustment. Meanwhile, a gap is provided between the base 100 and the movable seat 200 which are oppositely disposed, in order to allow the movable seat 200 to have a certain movement space and to be movable with respect to the base 100.

When the deformable component is an electrostrictive component, the electrostrictive component deforms under the action of current; when the deformable part is the temperature control deformable part, the temperature of the temperature control deformable part can be changed by introducing current to the temperature control deformable part, and then the temperature control deformable part is also deformed. The deformable element in the embodiments of the present application therefore has the particular feature of being deformable by the application of an electric current. In some embodiments, the deformable member may be an entire electrically deformable member, or an entire temperature-controlled deformable member, or a part of the deformable member may be an electrically deformable member, and the rest may be a temperature-controlled deformable member.

According to the actual shaking condition of the reflection module, the two first deformable parts 401 can only generate deformation difference to drive the movable seat 200 to rotate and adjust in one direction, the two second deformable parts 402 can only generate deformation difference to drive the movable seat 200 to rotate and adjust in the other direction, and the two first deformable parts 401 and the two second deformable parts 402 can both generate deformation difference to drive the movable seat to adjust in two different directions.

In other embodiments, the number of first deformable members 401 may also be three, four, five, six or more, and likewise the number of second deformable members 402 may also be three, four, five, six or more. Only a plurality of first deformable parts are arranged, so that the control module can control the deformation quantity of each first deformable part through current and further control the deformation difference among different first deformable parts, and therefore the movable seat can rotate in a certain axial direction; and as long as a plurality of second deformable parts are arranged, the control module can control the deformation amount of each second deformable part through current, and further control the deformation difference between different second deformable parts, thereby realizing the rotation of the movable seat in the other axial direction.

In the embodiment of the present application, the deformable member 400 is fixed between the base 100 and the movable seat 200 to which the light conversion element 300 is fixed, and the deformable member 400 is disposed as at least two first deformable members 401 along the first axis P1 and at least two second deformable members 402 along the second axis P2, the first axis P1 and the second axis P2 are both located on the plane of the base 100 connected to the deformable member 400, and the first axis P1 and the second axis P2 are not parallel but intersect. Utilize the characteristic that deformable part 400 can take place deformation under the electric current effect, change the parameter that reflection module takes place the shake into output current through control module, make the deformable part on the different axes produce a setting variation under the electric current effect to utilize this kind of deformation difference to realize adjusting the displacement of commentaries on classics light component 300, thereby compensate the regulation to the shake displacement that reflection module takes place, realize better anti-shake effect.

Specifically, the two first deformable components 401 generate a deformation difference under the action of current, for example, one first deformable component extends, and the other first deformable component does not change, so that the deformation difference is generated, for the movable seat 200 fixedly connected with the two first deformable components 401, the movable seat 200 is lifted by the first deformable component equivalent to the extension, so that the movable seat 200 rotates around a direction perpendicular to the first axis P1 due to the deformation difference, and further, the light conversion element is driven to rotate; the two second deformable parts 402 are deformed under the action of the current, for example, one second deformable part is elongated, and the other second deformable part is unchanged, so that the deformation difference is generated, for the movable seat 200 fixedly connected with the two second deformable parts 403, it is equivalent to that the elongated second deformable part raises the movable seat 200, so that the movable seat 200 rotates around the direction perpendicular to the second axis P2 due to the deformation difference, and the light conversion element is further driven to rotate. Therefore, the displacement that the light conversion element shakes and produces can be adjusted, compensated in two different directions to this application embodiment, compare the anti-shake that only can the single direction, have better anti-shake effect. Furthermore, in the embodiment of the present application, the rotating shaft structure is not disposed between the base 100 and the movable seat 200 to connect the two, but the deformable component 400 is used to connect the two, and a gap is formed between the base 100 and the movable seat 200, so that the problem of friction between the movable seat 200 and the base 100 due to the rotating shaft structure can be avoided, and the anti-shake is more accurate.

It should be noted that the deformation difference between the two first deformable components may be that one of the first deformable components is not deformed and the other deformable component is deformed to a certain extent, or may be that both the two first deformable components are deformed and the deformation amount of one of the deformable components is larger, so that the deformation difference is generated. The deformation differences between different second deformable parts are also the same and will not be described in detail.

In the embodiment of the present application, the light conversion element 300 may be fixedly attached to the movable base 200 by glue. Through the fixed light component that changes that pastes of glue, can make the fixed mounting operation between light component and the movable seat more convenient, fixed connection between the two also more reliable, light component's anti-shake adjusts the precision also higher. It can be understood that the light conversion element may also be fixedly mounted on the movable seat by other fixing connection manners, for example, the light conversion element is fixedly mounted on the movable seat by a snap connection manner or an interference fit connection manner.

In the embodiment of the present application, the light conversion element 300 is used for converting the light incident from the light input axis Z1 to the light output axis Z2, and the light conversion element 300 may be a prism or a plane mirror.

For optimizing the anti-shake effect, make the anti-shake more convenient and accurate, deformable component adopts the symmetry to set up in this application embodiment. Referring to fig. 4, as an alternative embodiment, in the embodiment of the present application, the first axis P1 perpendicularly intersects the second axis P2, two first deformable members 401 are symmetrically disposed on both sides of the second axis P2, and two second deformable members 42 are symmetrically disposed on both sides of the first axis P1. The deformable parts on the two axes are arranged according to axial symmetry, so that the rotation displacement of the movable seat and the light conversion element can be controlled more conveniently. Taking the axisymmetrical arrangement of the two first deformable members 401 as an example, when the two first deformable members 401 generate deformation difference, the movable seat 200 can rotate around the direction perpendicular to the first axis P1 (i.e. around the second axis P2), for example, around the second axis P2 in fig. 4; when the two first deformable members 401 are restored to the original state without deformation and without the need of shake compensation of the reflective module, the movable seat 200 rotates counterclockwise around the second axis P2, and the rotational displacement of the movable seat 200 is the same as the rotational displacement of the movable seat when the movable seat rotates clockwise around the second axis P2. However, if the movable seat is arranged non-axisymmetrically, the rotational displacement of the movable seat in the clockwise rotation is different from the rotational displacement in the counterclockwise rotation, although the rotational displacement adjustment of the movable seat in two different axial directions can be achieved by utilizing the difference in deformation of the variable member. Therefore, the axial symmetry is adopted, so that the convenient and accurate anti-shaking is facilitated.

In the embodiments of the present application, other numbers of first deformable members and second deformable members may be used in addition to two first deformable members and two second deformable members. To satisfy the axisymmetric arrangement, it is preferable to employ an even number of the first deformable members and an even number of the second deformable members for more convenient and accurate anti-shake.

Referring to fig. 5, as another alternative, in the present embodiment, another symmetrical arrangement may be adopted, in which the two first deformable members 401 and the two second deformable members 402 are still symmetrically arranged, but the first axis P1 and the second axis P2 intersect and are not perpendicular to each other. Adopt this setting, also can guarantee the movable seat at the in-process that rotates and reset, the rotation displacement volume is the same, does benefit to more convenient control anti-shake.

In order to further optimize the anti-shake effect and make the anti-shake operation easier to control, the embodiment of the present application associates one of the first axis and the second axis with the light direction of the light conversion element. With continued reference to fig. 4, in the embodiment of the present application, when the first axis P1 and the second axis P2 are perpendicular to each other, the first axis P1 is located in a plane formed by the light incoming axis Z1 and the light outgoing axis Z2. That is, the light conversion element 300 is used to convert the light ray entering the direction of the light axis Z1 to the direction of the light axis Z2, and the first axis P1 is located in the plane formed by the two light axes, so that the advantage of this arrangement is that: when only the direction around the optical axis Z2 is required to adjust the light-converting element 300, this can be achieved by adjusting only the difference in deformation of the two second deformable members 402. It will be appreciated that the second axis P2 may also be disposed in the plane formed by the two optical axes.

If neither the first axis P1 nor the second axis P2 is disposed in the plane formed by the two optical axes, even if only the direction of the optical axis Z2 needs to be adjusted to the light conversion element 300, it still needs to be adjusted for both the first deformable members 401 and the second deformable members 402. Therefore, one of the first axis and the second axis is arranged in a plane formed by the two optical axes, so that the structure is optimized, the anti-shake effect is further improved, and the anti-shake operation is more convenient and faster.

In the embodiment of the present application, when deformable member 400 is an electro-deformable member, the electro-deformable member is an electroactive polymer or carbon nanotube; when deformable member 400 is a temperature-controlled deformable member, the temperature-controlled deformable member is a memory alloy or a bimetal.

Among them, the electro-deformable parts such as electroactive polymers and carbon nanotubes have good responsiveness to current, and can be deformed such as expansion, contraction and bending under the action of current. The memory alloy is an alloy material which can eliminate the deformation of the memory alloy at a lower temperature after being heated and recover the original shape of the memory alloy before the deformation, namely the memory alloy has the memory effect. The memory alloy is heated after being electrified, and the internal crystal structure of the memory alloy is changed after being heated by the principle of thermal shrinkage and cold expansion, so that the memory alloy can be restored to the original shape. Bimetallic strip is a composite material composed of two or more metals or other materials having suitable properties. The bimetallic strip is also called as a thermal bimetallic strip, and because the thermal expansion coefficients of all component layers are different, when the temperature changes, the deformation of the active layer is larger than that of the passive layer, so that the whole bimetallic strip can bend towards one side of the passive layer, and the curvature of the composite material changes to generate deformation.

In the embodiment of the present application, the deformable member 400 preferably uses a memory alloy cylinder, and the memory alloy cylinder is deformed after being heated by electricity to realize the function of the deformable member.

In an embodiment of the application, the control module comprises an inclination detector and a processor which are electrically connected, the inclination detector is used for detecting a jitter parameter, converting the jitter parameter into an electric signal and transmitting the electric signal to the processor, the processor is used for receiving the electric signal, calculating a compensation deformation amount according to the electric signal and outputting current to the deformable parts after calculation, the two first deformable parts are used for deforming under the action of the current and generating deformation difference, and/or the two second deformable parts are used for deforming under the action of the current and generating deformation difference. The tilt detector may be a gyroscope, for example.

In the embodiment of the application, some shaking parameters when the reflection module shakes can be detected through an inclination detector such as a gyroscope, the shaking parameters are converted into electric signals to be transmitted to a processor, after the processor receives the electric signals, the deformation quantity which needs to be compensated for shaking due to shaking can be calculated according to the electric signals, and current is output to the first deformable part and/or the second deformable part after calculation, so that the first deformable part and/or the second deformable part generate certain deformation difference under the action of the current, and the deformation difference enables the movable seat to drive the light rotating element to perform compensation rotation, so that the influence caused by shaking of the reflection module is counteracted.

Referring to fig. 6 and 7, there is shown another reflection module based on the reflection module shown in fig. 1 to 5, the reflection module further includes an elastic member 500 disposed around the deformable member 400, one end of the elastic member 500 is fixedly connected to the base 100, and the other end is fixedly connected to the movable base 200. Positioning resilient member 500 around deformable member 400 can assist in the repositioning of the deformable member.

In the embodiment of the present application, the elastic member 500 is fitted around the outer circumference of the deformable member 400. On one hand, when the deformable member 400 deforms under the power-on condition, the elastic member 400 can be driven to deform along with the fact that the deformable member 400 is stretched, and on the other hand, when the power-on condition of the deformable member 400 is stopped, the elastic member 500 in the stretching state helps to drive the deformable member 400 to return to the original state. The elastic member 500 may be a spring, for example.

In other alternative embodiments, the resilient member may also be disposed adjacent to the deformable member. That is, the elastic member is not fitted around the outer periphery of the deformable member, but is independently disposed around the deformable member adjacent to the deformable member. In this case, the elastic member also functions to assist the restoration.

Along the light entering direction of lens module, this lens module includes in proper order: the image sensor comprises a reflection module 10, a lens group 20, a filter 30 and a photosensitive chip 40. For example, the lens group 20 may include one lens, and the lens group 20 may also include three lenses, as shown in fig. 8, the lens group 20 includes a first convex lens, a concave lens and a second convex lens, in this embodiment, different lens groups 20 may be obtained by using different lens combinations according to different requirements of the periscopic lens module on the focal length of the lens, which is not limited herein.
