Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of automotive parts manufacturing, and in particular, to an anti-peeping glass assembly and a vehicle. Background Art

[0002] With the rapid development of electric vehicles, the automotive industry is increasingly moving towards intelligence, electronics, and digitalization, and many automotive designs have also undergone huge reforms. In recent years, with the development of electronic and electrical technologies and people's emphasis on privacy, for example, all the window glasses of ordinary cars are of the two-way perspective style, resulting in passers-by being able to clearly see every move of the driver and passengers inside the known car, leaving no privacy protection at all. The electric anti-peeping solution for the window can effectively solve whether the car owner and passengers choose to transmit the information inside the car to the outside.

[0003] In the related art, a liquid crystal layer, an electrochromic layer, etc. are provided between the double-layer glasses, and then whether it is in a transparent state is controlled by an electric field to achieve anti-peeping or not. However, it has problems of poor light transmission effect and complex structure. Summary of the Invention

[0004] In view of this, the embodiments of the present application provide an anti-peeping glass assembly and a vehicle, which have the advantages of good light transmission effect and simple structure.

[0005] To achieve the above object, a first aspect of the embodiments of the present application provides an anti-peeping glass assembly, which includes a first transparent substrate, a second transparent substrate, at least one optical path module, and a driving component. Among them, the first transparent substrate and the second transparent substrate are arranged opposite to each other, and the two sides of the first transparent substrate and the second transparent substrate facing away from each other are the observation side and the anti-peeping side respectively; at least one optical path module is arranged between the first transparent substrate and the second transparent substrate, and each optical path module includes a polarization light generating member and at least two lenses arranged in sequence along a first direction, and the at least two lenses include at least one convex lens and at least one concave lens; the driving component is in transmission connection with at least one lens, and is used to drive at least one lens to move, in the first direction, to change the optical path angle of the polarized light after passing through the lens, so that the optical path module is in a first optical path state or a second optical path state; when in the first optical path state, the polarized light passes through the second transparent substrate and exits parallel to the first direction; when in the second optical path state, the polarized light diverges away from the first direction and exits outside the second transparent substrate; wherein, the first direction is perpendicular to the plane where the second transparent substrate is located, and points from the observation side to the anti-peeping side.

[0006] Specifically, the first transparent substrate and the second transparent substrate are disposed opposite to each other, and their sizes and the distance therebetween are not limited, as long as at least one optical path module can be accommodated between the two substrates. The two sides of the first transparent substrate and the second transparent substrate facing away from each other are the observation side and the anti-peeping side respectively. Here, the observation side and the anti-peeping side specifically refer to, for example, in the anti-peeping application scenario of a vehicle window, the vehicle window is a double-layer glass, the first transparent substrate refers to one of the two layers of glass close to the vehicle occupants, and the second transparent substrate refers to the layer of glass away from the vehicle occupants, that is, the observation side refers to the side close to the vehicle occupants, and the anti-peeping side refers to the side away from the vehicle occupants, that is, the anti-peeping side refers to the outside of the vehicle, which is used to prevent people outside the vehicle from seeing the scene inside the vehicle from the anti-peeping side. Also, for example, similarly, in the anti-peeping application scenario of an indoor window, the observation side refers to the side close to the interior, and the anti-peeping side is the side close to the exterior. Among them, at least one optical path module is disposed between the first transparent substrate and the second transparent substrate, and each optical path module includes a polarization light generating member and at least two lenses arranged in sequence along a first direction. Here, the first direction is perpendicular to the plane where the second transparent substrate is located and points from the observation side to the anti-peeping side, that is, the polarization light generating member is disposed close to the observation side. The polarization light generating member can be used to convert the incident light passing through the first transparent substrate, that is, the light diverging in various directions passing through the first transparent substrate, into polarized light with a single polarization direction. Compared with controlling the light diverging in various directions, the polarized light with a single polarization direction is easier to control.

[0007] Further, along the first direction, at least two lenses are disposed after the polarization light generating member, which can be used to adjust the optical path direction of the polarized light through the lenses. Among them, at least two lenses include at least one convex lens and at least one concave lens. The polarized light passing through the convex lens can be converged to change the optical path direction of the polarized light, and the polarized light passing through the concave lens can be diverged to change the optical path direction of the polarized light. Here, at least two lenses means that the minimum number of lenses is two, and it can also be three, four, etc., as long as the minimum number of lenses is two, and the specific number is not limited. For example, when at least two lenses are two lenses, only one convex lens and one concave lens are included in the two lenses, both are arranged along the first direction, and the principal optical axes of each lens are on a straight line. By adjusting the distance between the convex lens and the concave lens, the polarized light can be made to exit through the second transparent substrate along a direction parallel to the first direction. At this time, the people on the anti-peeping side can observe the scene inside the vehicle. Similarly, because the optical path is reversible, the people inside the vehicle can also observe the scene outside the vehicle. Moreover, in this case, since the polarized light exits through the second transparent substrate parallel to the first direction and the light loss of the polarized light during passing through the lenses is very small, the light transmission effect is good, avoiding the problem of poor light transmission effect in the related art when using an anti-peeping film or an electrochromic layer.

[0008] Furthermore, since the driving component is in transmission connection with at least one lens and can drive the lens in transmission connection therewith to move, the optical path behind the moving lens can be changed in the first direction, so that the optical path module is in a first optical path state or a second optical path state. When in the first optical path state, the polarized light passes through the second transparent substrate and exits parallel to the first direction; when in the second optical path state, the polarized light diverges away from the first direction and exits outside the second transparent substrate. Specifically, when the driving component drives the lens in transmission connection therewith to move, the optical path module being in the first optical path state may specifically refer to making the principal optical axes of each convex lens and each concave lens parallel to the first direction. Correspondingly, at this time, the polarized light passes through the second transparent substrate and exits, and the light exiting through the second transparent substrate is parallel to the light of the polarized light generated by the polarized light generating member; or when the driving component drives the lens in transmission connection therewith to move, the optical path module being in the second optical path state may specifically refer to at least one lens in transmission connection with the driving component moving, so that the relative position between the moving lens and the first transparent substrate changes, and the optical path angle behind the moving lens can be changed to be incident on the second transparent substrate. Correspondingly, the polarized light diverges away from the first direction and exits outside the second transparent substrate, that is, the polarized light fails to exit from the anti-peeping side, that is, the people outside the vehicle cannot observe the scene inside the vehicle at this time. Thus, it can be applied to the scene when the vehicle window is in the anti-peeping state. With the above design, by driving at least one lens in transmission connection with the driving component to move, the optical path module can be switched between the first optical path state and the second optical path state, that is, corresponding to two application scene states of non-anti-peeping and anti-peeping. Compared with the method of setting an electrochromic layer, etc., since the embodiment of the present application does not require additional production of electrochromic materials to form an anti-peeping layer and addition of a complex circuit for controlling the color-changing layer, the anti-peeping glass component has a simple structure, can be freely selected whether to be anti-peeping according to the will of the people inside the vehicle, and has a good light transmission effect.

[0009] Here, it should be noted that by pre-adjusting and designing the distance between at least two lenses, when in the first optical path state, the polarized light passes through the second transparent substrate and exits parallel to the first direction. On the basis of achieving the first optical path state, further, the driving component drives at least one lens in transmission connection therewith to move to debug the situation where the polarized light fails to exit from the second transparent substrate.

[0010] In addition, it should be noted that when the driving component drives at least one lens to move, the movement form of the lens is not limited. For example, it can be driving the lens in transmission connection therewith to rotate or translate relative to the first transparent substrate, etc., as long as it can move to make the optical path module in the first optical path state or the second optical path state.

[0011] In a possible implementation of the present application, there is one convex lens and one concave lens in each optical path module. Herein, on the one hand, due to the limited space between the first transparent substrate and the second transparent substrate, compared with the setting of multiple convex lenses and multiple concave lenses, the setting of one convex lens and one concave lens occupies less space, is convenient for layout, and has a simple structure; on the other hand, it is convenient to control the relative position between the convex lens and the concave lens.

[0012] In a possible implementation of the present application, the convex lens is located between the polarized light generating member and the concave lens. Herein, when there is no need for anti-peeping, that is, when polarized light needs to be emitted from the second transparent substrate parallel to the first direction, if the polarized light is first diverged by the concave lens, some light rays will directly diverge outside the second transparent substrate without passing through the second transparent substrate, which will reduce the light intensity and thus affect the light transmission effect. Therefore, here, the convex lens is arranged close to the polarized light generating member, that is, the polarized light is first converged by the convex lens and then diverged by the concave lens, which is convenient for all polarized light to be emitted from the second transparent substrate parallel to the first direction to achieve a better light transmission effect.

[0013] In a possible implementation of the present application, the driving assembly is in transmission connection with the convex lens, and the driving assembly is used to drive the convex lens to deflect relative to the first transparent substrate so that the optical path module is in the first optical path state or the second optical path state. Herein, since the convex lens has a converging effect on the incident light, compared with driving the concave lens to deflect, it is easier to control the converging position of the incident polarized light by adjusting the movement of the convex lens, and thus it is convenient to control whether the light converged by the convex lens can be incident on the concave lens located behind it, so that the optical path module is in the first optical path state or the second optical path state.

[0014] In a possible implementation of the present application, the optical path module includes two transparent connecting members, namely the first connecting member and the second connecting member. The convex lens is fixedly connected to the first connecting member, and the concave lens is fixedly connected to the second connecting member. In this way, it is convenient to fix the convex lens and the concave lens through the connecting members, so as to further facilitate accurately changing the relative position between the convex lens and the concave lens by the driving assembly.

[0015] In a possible implementation manner of the present application, the first connecting member is in transmission connection with the driving assembly. The driving assembly is used to drive the first connecting member to rotate, so as to drive the convex lens to deflect relative to the first transparent substrate, so that the optical path module is in a first optical path state or a second optical path state. Here, since the outer contour of the convex lens is a curved surface shape, when directly connected to the driving assembly, the connection form is complex and it is not easy to control the deflection of the convex lens. Therefore, it is connected in transmission through the first connecting member fixedly connected to the convex lens. Among them, the first connecting member can be designed as a plate-like structure with a regular shape, so as to be directly connected in transmission with the driving assembly. Furthermore, the first connecting member drives the convex lens fixedly connected to it to deflect, so that the optical path module is in a first optical path state or a second optical path state.

[0016] In a possible implementation manner of the present application, at least two optical path modules are arranged in an array between the first transparent substrate and the second transparent substrate. For example, a plurality of optical path modules are arranged in multiple rows and columns in a neat arrangement between the first transparent substrate and the second transparent substrate. In this way, it is convenient to uniformly control each optical path to be in the first optical path state or the second optical path state at the same time.

[0017] In a possible implementation manner of the present application, the driving assembly includes a driving member and a transmission member. One end of the transmission member is in transmission connection with the output shaft of the driving member. Each optical path module is rotatably connected to the transmission member through a first connecting member. For example, when the driving member drives the transmission member to rotate, the first connecting members of each optical path module can generate the same rotation action. In this way, it is possible to synchronously control each optical path module to be in the first optical path state or the second optical path state at the same time.

[0018] In a possible implementation manner of the present application, the connecting member is made of a light-transmitting metal material. Here, since the connecting member needs to be fixedly connected to the lens, and some connecting members also need to be connected to the transmission member, it often requires high strength. Therefore, compared with the connecting member made of ordinary light-transmitting glass, the connection of the light-transmitting metal material not only does not affect the propagation of light, but also has high strength to improve the reliability of the entire anti-peeping glass assembly.

[0019] In the second aspect of the embodiments of the present application, a vehicle is provided. The vehicle includes a control unit and the anti-peeping glass assembly according to any one of the first aspect. Among them, the anti-peeping glass assembly is used as at least one window structure of the vehicle; the control unit is used to control the driving assembly of the anti-peeping glass assembly to respond, so that the driving assembly drives at least one lens to move. Since the vehicle adopts the anti-peeping glass assembly according to any one of the first aspect, it has the same technical effects, that is, it has the advantages of good light-transmitting effect and simple structure.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application in detail with reference to the accompanying drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not used to limit the scope of the present application.

[0029] In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they can change accordingly with the change of the orientation in which the components in the drawings are placed.

[0031] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0032] In the embodiments of the present application, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0033] In the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplarily" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner.

[0034] The anti-peeping design can be widely applied to scenarios such as anti-peeping of indoor windows and anti-peeping of vehicle windows. Currently, the anti-peeping solution mainly relies on anti-peeping films, but there are the following deficiencies. For example, in the application scenario of anti-peeping of vehicle windows, although it is possible to prevent the scene inside the vehicle from being seen from outside the vehicle, which protects the privacy of the users inside the vehicle, at the same time, the users inside the vehicle cannot see the scene outside the vehicle, that is, the users inside the vehicle cannot switch between the anti-peeping and non-anti-peeping modes at any time.

[0035] Therefore, the embodiments of the present application provide a vehicle, which includes a control unit and an anti-peeping glass assembly. The anti-peeping glass assembly is used as at least one window structure of the vehicle; the control unit is used to control the driving assembly of the anti-peeping glass assembly to respond, so that the driving assembly drives at least one lens to move. The anti-peeping glass assembly can effectively solve the problem of whether the vehicle owner and passengers choose to transmit the information inside the vehicle to the outside, that is, the vehicle owner can independently switch between the anti-peeping and non-anti-peeping modes at any time.

[0036] At present, the related technologies include setting a liquid crystal layer or an electrochromic layer between the double-layer glass to control whether it is transparent to achieve anti-peeping. However, there are problems such as poor light transmission effect and complex structure.

[0037] To this end, the present application also provides an anti-peep glass assembly, referring to Figures 1 to 6 The anti-peep glass assembly includes a first transparent substrate 11, a second transparent substrate 12, at least one optical path module 2 and a driving assembly 3. The first transparent substrate 11 and the second transparent substrate 12 are arranged opposite to each other and can be used as two substrates of a double-layer vehicle window glass, and the two opposite sides of the first transparent substrate 11 and the second transparent substrate 12 are respectively the observation side and the anti-peeping side; at least one optical path module 2 is arranged between the first transparent substrate 11 and the second transparent substrate 12, and each optical path module 2 includes a polarized light generating element 21 and at least two lenses 22 arranged in sequence along the first direction a, and the at least two lenses 22 include at least one convex lens 221 and at least one concave lens 222; the driving component 3 is connected to the at least one lens 22 in a transmission manner, and is used to drive the at least one lens 22 to move, along the first direction a, to change the optical path angle of the polarized light after passing through the lens 22, so that the optical path module 2 is in the first optical path state or the second optical path state; when in the first optical path state, the polarized light passes through the second transparent substrate 12 and is emitted parallel to the first direction a; when in the second optical path state, the polarized light is incident on the outside of the second transparent substrate 12 away from the first direction a. The first direction a is perpendicular to the plane where the second transparent substrate 12 is located, and points from the observation side to the anti-peeping side. In addition, it should be noted that the anti-peep glass assembly of the embodiment of the present application can be applied to multiple scenarios, such as anti-peeping of windows in a room, anti-peeping of vehicle window glass 1, anti-peeping of electronic display devices, etc., without specific limitation. For the convenience of description, the embodiment of the present application is described by taking the anti-peeping of vehicle window glass 1 as an example unless otherwise specified.

[0038] Specifically, the first transparent substrate 11 and the second transparent substrate 12 are disposed opposite to each other, and their sizes and the distance between the two are not limited. It is only required that at least one optical path module 2 can be accommodated between the two substrates. In addition, the specific materials of the first transparent substrate 11 and the second transparent substrate 12 are not limited. For example, they can be ordinary transparent glass, or transparent tempered glass, etc. The two sides of the first transparent substrate 11 and the second transparent substrate 12 facing away from each other are respectively the viewing side and the anti-peeping side. Here, the viewing side and the anti-peeping side specifically refer to, for example, in the anti-peeping application scenario of a car window, the car window glass 1 is a double-layer glass. The first transparent substrate 11 refers to one of the two layers of glass close to the passengers inside the car, and the second transparent substrate 12 refers to the layer of glass far from the passengers inside the car. That is, the viewing side refers to the side close to the passengers inside the car, and the anti-peeping side refers to the side far from the passengers inside the car, that is, the anti-peeping side refers to the outside of the vehicle, which is used to prevent people outside the car from seeing the scene inside the car from the anti-peeping side. For another example, similarly, in the anti-peeping application scenario of an indoor window, the viewing side refers to the side close to the interior of the room, and the anti-peeping side is the side close to the outside of the room. Among them, at least one optical path module 2 is disposed between the first transparent substrate 11 and the second transparent substrate 12, and each optical path module 2 includes a polarization light generating member 21 and at least two lenses 22 arranged in sequence along the first direction a. Here, the first direction a is perpendicular to the plane where the second transparent substrate 12 is located and points from the viewing side to the anti-peeping side, that is, the polarization light generating member 21 is disposed close to the viewing side. The polarization light generating member 21 can be used to convert the incident light passing through the first transparent substrate 11, that is, the light diverging in various directions passing through the first transparent substrate 11, into polarized light with a single polarization direction. Compared with controlling the light diverging in various directions, the polarized light with a single polarization direction is easier to control.

[0039] Continuing, referring to Figure 1 and Figure 2 , along the first direction a, at least two lenses 22 are disposed after the polarization light generating member 21, which can be used to adjust the optical path direction of the polarized light through the lenses 22. Among them, at least two lenses 22 include at least one convex lens 221 and at least one concave lens 222. The polarized light passing through the convex lens 221 can be converged to change the optical path direction of the polarized light, and the polarized light passing through the concave lens 222 can be diverged to change the optical path direction of the polarized light. Here, at least two lenses 22 means that the minimum number of lenses 22 is two, and it can also be three, four, etc. It only needs to satisfy that the minimum number of lenses 22 is two, and the specific number is not limited. For example, referring to Figure 1, at least two lenses 22 are two lenses 22, and one of the two lenses 22 is a convex lens 221 and the other is a concave lens 222. The polarization light generating member 21, the convex lens 221, and the concave lens 222 are arranged in sequence along the first direction a, and the principal optical axes of the convex lens 221 and the concave lens 222 are on the same straight line. By adjusting the distance between the convex lens 221 and the concave lens 222, the polarized light can be made to exit through the second transparent substrate 12 in a direction parallel to the first direction a. At this time, the people on the anti-peeping side can observe the scene inside the vehicle. Similarly, due to the reversibility of the optical path, the people inside the vehicle can also observe the scene outside the vehicle. Moreover, in this case, since the polarized light exits the second transparent substrate 12 parallel to the first direction a and the light loss of the polarized light is very small during the process of passing through multiple lenses, the light transmission effect is good, avoiding the problem of poor light transmission effect in the related art when using an anti-peeping film or an electrochromic layer. Here, usually the light transmittance of the anti-peeping film or the electrochromic layer is less than 30%.

[0040] Further, referring to Figure 1 and Figure 2 , since the driving assembly 3 is in transmission connection with at least one lens 22, the lens 22 in transmission connection with it can be driven to move, so that the optical path of the polarized light after passing through the lens 22 can be changed along the first direction a, so that the optical path module 2 is in a first optical path state or a second optical path state. When in the first optical path state, the polarized light passes through the second transparent substrate 12 and exits parallel to the first direction a; when in the second optical path state, the polarized light diverges away from the first direction a and exits outside the second transparent substrate 12. Specifically, for example, referring to Figure 2 and Figure 5 , when the driving assembly 3 drives the lens in transmission connection with it to move, the first optical path state of the optical path module 2 may specifically refer to making the principal optical axes of each convex lens 221 and each concave lens 222 parallel to the first direction a. Correspondingly, at this time, the polarized light passes through the second transparent substrate 12 and exits, and the light exiting through the second transparent substrate 12 is parallel to the light of the polarized light generated by the polarization light generating member 21; or when the driving assembly 3 drives the lens in transmission connection with it to move, referring to Figure 3 , Figure 4 and Figure 6, the optical path module 2 being in the second optical path state specifically means that at least one lens connected to the driving component in a transmission manner moves, so that the relative position of the lens generating the movement and the first transparent substrate 11 changes, and the optical path behind the lens generating the movement can be changed to not be incident on the second transparent substrate 12. Accordingly, at this time, the polarized light is diverged away from the first direction a to the outside of the second transparent substrate 12, that is, the polarized light fails to be emitted from the anti-peeping side, that is, at this time, the people outside the vehicle cannot observe the scene inside the vehicle, so that it can be applied to the scene when the window is in the anti-peeping state. With the above design, the at least one lens 22 connected to it in a transmission manner can be driven by the driving component 3 to move, so that the optical path module 2 can switch between the first optical path state and the second optical path state, that is, corresponding to the two application scene states of non-peeping and anti-peeping. Compared with the method of setting an electrochromic layer, etc., since the embodiment of the present application does not need to additionally make an electrochromic material to form an anti-peeping layer and add a complex circuit for controlling the color-changing layer, the structure of the anti-peeping glass component is simple, and the people inside the vehicle can choose whether to be anti-peeping at their own will, and the light transmission effect is good.

[0041] For example, refer to Figure 2 , Figure 3 and Figure 4 The optical path module 2 has two lenses 22, namely a convex lens 221 and a concave lens 222, and the polarized light generating element 21, the convex lens 221, and the concave lens 222 are sequentially arranged along the first direction a. Figure 1 , is a schematic diagram of the optical path when the optical path module 2 is in the first optical path state. At this time, the polarized light passing through the polarized light generating element 21 converges after passing through the convex lens 221 and then diverges again after being incident on the concave lens 222 behind, so that the polarized light is emitted parallel to the first direction a after passing through the second transparent substrate 12. Here, the relative distance between the convex lens 221 and the concave lens 222 can be adjusted in advance, such as setting the concave lens 222 within a range less than one times the focal length of the convex lens 221, so that the polarized light is finally emitted from the second transparent substrate 12 parallel to the first direction a. Figure 3 and Figure 4 is a schematic diagram of the optical path when the optical path module 2 is in the second optical path state, wherein: Figure 3 In the embodiment, the convex lens 221 connected to the convex lens 221 is driven by the driving component 3 to deflect, so that when the main optical axis of the convex lens 221 is at a preset angle with the first direction a, the polarized light converged by the convex lens 221 cannot be incident on the concave lens 222 behind it, and then the polarized light cannot be emitted from the second transparent substrate 12, that is, the incident light inside the car cannot be received on the anti-peep side, and the scene inside the car cannot be seen on the anti-peep side.

[0042] For example, refer to Figure 1 and Figure 4, is to drive the concave lens 222 connected to it through the driving component 3 to deflect, so that when the main optical axis of the concave lens 222 is at a preset angle with the first direction a, it can appear that although the polarized light converged by the convex lens 221 can be incident on the concave lens 222, after being diverged by the concave lens 222, the polarized light emitted from the concave lens 222 cannot be incident on the second transparent substrate 12. Therefore, the scene inside the car cannot be seen on the anti-peeping side.

[0043] Here, it should be noted that Figure 4 It may also be that only a small portion of the polarized light after being diverged by the concave lens 222 is emitted from the second transparent substrate 12, and the small portion of light emitted from the second transparent substrate 12 is emitted approximately in a direction parallel to the transparent substrate. At this time, the small portion of light usually cannot enter the field of vision of the personnel on the anti-peep side outside the vehicle. In addition, even if the small portion of light can be received, the scene inside the vehicle cannot be seen clearly because it is too divergent.

[0044] For example, refer to Figure 5 and Figure 6 , is a schematic diagram of the optical path of at least two lenses 22 including two convex lenses 221 and one concave lens 222, and the concave lenses 222 are arranged between the two convex lenses 221. Figure 5 , is a schematic diagram of the optical path when the optical path module 2 is in the first optical path state. At this time, the polarized light first passes through the first transparent substrate 11 and then converges. The converged polarized light is diverged through the concave lens 222, and then passes through the lens 22 close to the second transparent substrate 12 to converge into parallel light parallel to the first direction a, so that the polarized light finally passes through the second transparent substrate 12 and is emitted parallel to the first direction a. Figure 6 , is a schematic diagram of the optical path when the optical path module 2 is in the second optical path state, and the driving component 3 drives the concave lens 222 connected thereto to deflect relative to the first transparent substrate 11, so that when the main optical axis of the concave lens 222 is at a preset angle to the first direction a, the polarized light incident after being converged by the convex lens 221 can be incident on the concave lens 222, but after being diverged by the concave lens 222, the polarized light emitted from the concave lens 222 fails to be incident on the convex lens 221 close to the second transparent substrate 12, and no incident light is incident on the second transparent substrate 12, so the scene inside the car cannot be seen on the anti-peeping side. Here, for Figure 6 It is also possible to rotate one of the convex lenses 221 and the concave lens 222 at the same time, or to rotate the two convex lenses 221 at the same time, and so on. There is no specific limitation, as long as the polarized light can be prevented from being incident on the second transparent substrate 12. Here, the principle is the same and will not be repeated one by one.

[0045] It should be noted that the distance between at least two lenses 22 can be pre-adjusted to achieve that when in the first optical path state, the polarized light passes through the second transparent substrate 12 and is emitted parallel to the first direction a. On the basis of achieving the first optical path state, the driving component 3 continues to drive at least one lens 22 connected to it to move, so as to debug the situation when the polarized light fails to be emitted from the second transparent substrate 12.

[0046] In addition, it should be noted that when the driving component 3 drives at least one lens 22 to move, the movement form of the lens 22 is not limited. For example, the driving component 3 may drive the lens 22 connected to it to rotate or translate relative to the first transparent substrate 11, etc. Among them, the deflection movement of the lens 22 may be rotation around its main optical axis, or rotation around the edge of the lens 22 away from its main optical axis. It is not specifically limited. It can deflect relative to the first transparent substrate 11 until the optical path module 2 is in the first optical path state or the second optical path state. Preferably, the driving component 3 is used to drive at least one lens 22 to rotate around its main optical axis, and the space occupied during the movement is small, so as to adapt to the relatively limited space of the first transparent substrate 11 and the second transparent substrate 12.

[0047] In some embodiments, reference Figure 2 , Figure 3 and Figure 4 , each optical path module 2 has one convex lens 221 and one concave lens 222. On the one hand, due to the limited space between the first transparent substrate 11 and the second transparent substrate 12, compared with the arrangement of multiple convex lenses 221 and multiple concave lenses 222, the arrangement of one convex lens 221 and one concave lens 222 occupies less space, is easy to arrange, and has a simple structure; on the other hand, the driving component 3 can be connected to only one of the lenses in a transmission manner, so as to control the relative position between the convex lens 221 and the concave lens 222.

[0048] Continue, refer to Figure 2 , Figure 3 and Figure 4 , the convex lens 221 is located between the polarized light generating element 21 and the concave lens 222. In this case, when anti-peeping is not required, that is, when the polarized light needs to be emitted from the second transparent substrate 12 parallel to the first direction a, if the polarized light first passes through the concave lens 222 to diverge, some light will not pass through the second transparent substrate 12 but will directly diverge outside the second transparent substrate 12, which will reduce the light intensity and thus affect the light transmission effect. Therefore, here, the convex lens 221 is arranged close to the polarized light generating element 21, that is, the polarized light first passes through the convex lens 221 to converge and then passes through the concave lens 222 to diverge, so that all polarized light can be emitted from the second transparent substrate 12 parallel to the first direction a, so as to achieve a better light transmission effect.

[0049] Reference Figure 3 Figure 3 , the driving component 3 is in transmission connection with the convex lens 221, the position of the concave lens 222 is relatively fixed with respect to the second transparent substrate 12, and the driving component 3 is used to drive the convex lens 221 to deflect relative to the first transparent substrate 11 so that the optical path module 2 is in the first optical path state or the second optical path state. Here, since the convex lens 221 has a converging effect on the incident light, compared with driving the concave lens 222 to deflect, it is easier to control the converging position of the convex lens 221 on the incident polarized light by adjusting the movement of the convex lens 221, and then it is convenient to control whether the light converged by the convex lens 221 can be incident on the concave lens 222 located behind it, so that the optical path module 2 is in the first optical path state or the second optical path state.

[0050] In some embodiments, reference Figure 2 and Figure 5 Figure 5 , the optical path module 2 includes two correspondingly arranged transparent connectors, namely the first connector 231 and the second connector 232, the convex lens 221 is fixedly connected to the first connector 231, and the concave lens 222 is fixedly connected to the second connector 232. In this way, it is convenient to fix the convex lens 221 and the concave lens 222 through the connectors, so as to further facilitate accurately changing the relative position between the convex lens 221 and the concave lens 222 by the driving component 3.

[0051] In some embodiments, reference Figure 1 、 Figure 2 and Figure 3 Figure 3 , the first connector 231 is in transmission connection with the driving component 3, and the driving component 3 is used to drive the first connector 231 to rotate so as to drive the convex lens 221 to deflect relative to the first transparent substrate 11 so that the optical path module 2 is in the first optical path state or the second optical path state. Here, since the outer contour of the convex lens 221 is a curved surface shape, when directly connected to the driving component 3, the connection form is complex and it is not easy to control the deflection of the convex lens 221. Therefore, it is in transmission connection through the first connector 231 fixedly connected to the convex lens 221, wherein the first connector 231 can be designed as a plate-like structure with a regular shape, so as to be directly in transmission connection with the driving component 3. Furthermore, the first connector 231 drives the convex lens 221 fixedly connected to it to deflect, so that the optical path module 2 is in the first optical path state or the second optical path state.

[0052] In some embodiments, reference Figure 1 and Figure 2 Figure 2 , at least two optical path modules 2 are arranged in an array between the first transparent substrate 11 and the second transparent substrate 12. For example, a plurality of optical path modules 2 are arranged in multiple rows and multiple columns in a neat arrangement between the first transparent substrate 11 and the second transparent substrate 12. In this way, it is convenient to uniformly control each optical path to be in the first optical path state or in the second optical path state simultaneously.

[0053] Referring to Figure 1 , the driving assembly 3 includes a driving member 31 and a transmission member 32. One end of the transmission member 32 is in transmission connection with the output shaft of the driving member 31. Each optical path module 2 is rotatably connected to the transmission member 32 through a first connecting member 231. For example, the transmission member 32 can be arranged parallel to the plane where the first transparent substrate 11 is located and penetrate through the entire vehicle window in a direction perpendicular to the first direction a. When the driving member 31 drives the transmission member 32 to rotate by a certain angle, the first connecting members 231 of each optical path module 2 can generate the same rotational movement. Thus, it is possible to synchronously control each optical path module 2 to be in the first optical path state or the second optical path state simultaneously. Among them, preferably, the driving member 31 is in the form of a micro motor, which is convenient for intelligent control, occupies a small space, and has high precision.

[0054] Referring to Figure 1 and Figure 2 , the connecting member is made of a light-transmitting metal material. Here, since the connecting member needs to fixedly connect the lens and some connecting members also need to be connected to the transmission member 32, it often requires high strength. Therefore, compared with the connecting member made of ordinary light-transmitting glass, the connecting member made of light-transmitting metal material not only does not affect the transmission of light but also has high strength to improve the reliability of the entire anti-peeping glass assembly.
