The embodiment of the invention provides an in-vehicle isolation system, which is shown in fig. 1 and comprises an isolation wall 1, image acquisition equipment 3 and a rearview mirror display 2; wherein the partition wall 1 is installed between a front seat and a rear seat in a vehicle and used for blocking or communicating the sight line between the front seat and the rear seat; the image acquisition device 3 is used for acquiring image data of the rear of the vehicle and transmitting the image data to the rearview mirror display 2 in the vehicle; the rear view mirror display 2 is installed in the vehicle to receive the image data and display when the line of sight between the front seat and the rear seat is blocked, and is in a mirror state when the line of sight between the front seat and the rear seat is communicated.
In the embodiment of the invention, when the sight between the front seat and the rear seat is blocked by the partition wall 1, the rearview mirror display 2 receives and displays the image data acquired by the image acquisition equipment 3, so that the safety of rear passengers is ensured, the driver can observe the road conditions behind the vehicle, and the driving safety is ensured.
Alternatively, the image acquisition device 3 may be mounted on the rear of the vehicle body to facilitate acquisition of image data from the rear of the vehicle. Alternatively, the rear-view display 2 is a device capable of switching the image display state and the mirror state, and the switching of the image display state and the mirror state can be achieved by changing polarized light. Optionally, the rear-view display 2 may include: an image display unit for emitting image light for displaying a desired image, and a mirror function unit which is disposed on the image display unit in a superimposed manner and can switch between an image transmission state of the transmitted image light and a mirror state of the reflected external light; the mirror function unit includes a reflection type polarization selection means for transmitting a first polarized light of a predetermined polarization axis and reflecting a second polarized light having a polarization axis intersecting the first polarized light, a transmission polarization axis changing means for switching between a transmission state in which the first polarized light is changed to the second polarized light and a transmission state in which the polarization axis of the incident polarized light is not changed, and an absorption type polarization selection means for transmitting one of the first polarized light and the second polarized light and absorbing the other of the polarized light, the reflection type polarization selection means being disposed in this order on the image display unit side; an image display unit includes image light polarization selection means for transmitting first polarized light and absorbing second polarized light, and the first polarized light transmitted through the image light polarization selection means is emitted as the image light.
In another embodiment of the present invention, as shown in fig. 2, the in-vehicle isolation system includes a control unit 11, where the control unit 11 is configured to receive a blocking instruction or a communication instruction triggered by a user, so as to control the isolation wall 1 to block or communicate a line of sight between the front seat and the rear seat; and controlling the rear view mirror display 2 to receive and display the image data after controlling the partition wall 1 to block the line of sight between the front-row seats and the rear-row seats; after controlling the partition wall 1 to communicate the line of sight between the front-row seats and the rear-row seats, the mirror display 2 is controlled to be in a mirror state. In order to facilitate the control of the partition wall 1 by a user (passenger or driver), the user-triggered instruction may be received by the control unit 11, and the partition wall 1 and the mirror display 2 may be controlled by the user in response to the user instruction by controlling the partition wall 1 and the mirror display 2, thereby improving the user experience.
As shown in fig. 2, the in-vehicle isolation system further includes a control switch 12 for transmitting a blocking instruction or a communication instruction to the control unit 11 through the control switch 12. The control switch 12 may be provided on the back of the front seat or at a location convenient for the rear passenger to operate. Alternatively, in addition to the control switch 12, a blocking instruction or a communication instruction may be sent to the control unit 11 by other means, such as sending a blocking instruction or a communication instruction to the control unit 11 by an application program, so that the control unit 11 realizes control of the partition wall 1 and the rearview mirror display 2.
Optionally, the partition wall 1 has a non-transparent state and a transparent state; for blocking the line of sight between the front row of seats and the rear row of seats when the partition wall 1 is in a non-transparent state; when the partition wall 1 is in a transparent state, it is used for communicating the line of sight between the front row seats and the rear row seats. The partition wall 1 is configured to block or communicate a line of sight between a front seat and a rear seat by switching between a non-transparent state and a transparent state.
When the partition wall 1 is in a transparent state and the open mode is opened, the rearview mirror display 2 is in a mirror state, and the road condition is observed through mirror reflection. When the partition wall 1 is in a non-transparent state and the privacy mode is started, the rearview mirror display 2 receives image data sent by the image acquisition equipment 3 arranged at the tail of the vehicle and displays the data content, so that a driver can observe the road condition of the tail of the vehicle conveniently. Therefore, the driver cannot observe the rear-row situation, the privacy safety of rear-row passengers is guaranteed, and meanwhile, the driver can observe the rear-row situation and the driving safety is guaranteed. The image capturing device 3 may be a camera, and the image capturing device 3 may be turned on after the partition wall 1 is in the non-transparent state, or may be in the on state all the time, which is not limited in the embodiment of the present invention.
Alternatively, the non-transparent state of the partition wall 1 may be realized in a specular reflection state, and the partition wall 1 may be switched between a specular reflection state and a transparent state, and the partition wall 1 may include a reflective polarization selection unit that transmits a first polarized light of a predetermined polarization axis and reflects a second polarized light whose polarization axis intersects the first polarized light, a transmissive polarization axis variable unit that switches a transmission state in which the incident first polarized light is changed to the second polarized light and a transmission state in which the polarization axis of the incident polarized light is not changed, and an absorptive polarization selection unit that transmits one of the first polarized light and the second polarized light and absorbs the other, similar to the principle of realizing the specular function in the rear-view display 2.
As another embodiment of the present invention, as shown in fig. 3, the partition wall 1 includes a substrate 13, a semi-transparent and semi-reflective film 14, and a liquid crystal dimming device 15, which are sequentially stacked; when the liquid crystal dimming device 15 is powered on or powered off, the partition wall 1 is in a specular reflection state or a transparent state. Alternatively, the liquid crystal dimming device 15 may be a passive LC device, which assumes a specular reflective state when the liquid crystal dimming device 15 is powered on, and a transparent state when the liquid crystal dimming device 15 is powered off; alternatively, the liquid crystal light-adjusting device 15 assumes a specular reflection state when it is powered off, and assumes a transparent state when the liquid crystal light-adjusting device 15 is powered on. Alternatively, the transflective film 14 may be a reflective polarizer film (RPM) or a cholesteric liquid crystal brightness enhancing film. The reflective polarizer film (RPM) structure may be about 800 layers of two material stacks having different refractive indices. Cholesteric phase is an important phase state of liquid crystals, in which the liquid crystals are arranged in layers and have a continuous helical structure, selectively reflecting incident light (like Bragg reflection of crystals). The cholesteric liquid crystal reflects circularly polarized light having the same rotation direction as the circularly polarized light and passes circularly polarized light having the opposite rotation direction, and the passed circularly polarized light passes through the lambda/4 wave plate to become linearly polarized light.
As still another embodiment of the present invention, the partition wall 1 includes a polymer dispersed liquid crystal dimming device; when the polymer dispersed liquid crystal dimming device is powered on or powered off, the polymer dispersed liquid crystal dimming device is in a scattering state or a transparent state. Wherein the polymer dispersed liquid crystal light adjusting device comprises Polymer Dispersed Liquid Crystal (PDLC) and when no voltage is applied to the two ends of the conductive substrate, the optical axis orientation of all liquid crystal microdroplets is disordered, and meanwhile, light is scattered when the light is incident to the PDLC film due to the optical anisotropy of the liquid crystal, so that the naked eye looks as frosted white opaque or semitransparent; when a certain driving voltage is applied to the two ends of the substrate, the long axes of the liquid crystal microdroplets are uniformly deflected along the direction of the electric field and finally are consistent with the direction of the electric field. When the ordinary refractive index of the liquid crystal matches the refractive index of the polymer, the incident light can pass smoothly, and the PDLC film becomes transparent. If the electric field is now removed, the interaction between the liquid crystal droplets and the polymer will cause the long axis orientation of the LC droplets to become disorganized again and the PDLC reverts to an opaque scattering state. Therefore, the state of the PDLC film can be freely switched by the voltage driving. As still another embodiment of the present invention, as shown in fig. 4, the partition wall 1 includes a substrate 13, a glue layer 16, and an electrochromic device 17 laminated in this order; the electrochromic device 17 is in a non-transparent or transparent state when it is powered on or off. It is noted that in an embodiment of the invention, the electrochromic device 17 is passive. For example, when the electrochromic device 17 is energized, it assumes a blue-black (but may be another color) i.e. in a non-transparent state; when the electrochromic device 17 is powered down, it assumes a transparent state.
In a further embodiment of the invention, the partition wall 1 is non-transparent and can be folded or unfolded; as shown in fig. 5, when the partition wall 1 is in the unfolded state, it serves to block the line of sight between the front row of seats and the rear row of seats; as shown in fig. 6, when the partition wall 1 is in a folded state, it is used to communicate the line of sight between the front row of seats and the rear row of seats. In this embodiment, the partition wall 1 may be folded and may exhibit a non-transparent state, such as a white reflective state or other colors. When the partition wall 1 is in the unfolded state, it is in the privacy mode, and when the partition wall 1 is in the folded state, it is in the open mode.
Optionally, the partition wall 1 is a projection curtain, and presents a white reflective state, and can be used as a projection screen. Optionally, as shown in fig. 5, the in-vehicle isolation system further includes a projector 4, so that a rear passenger can conveniently watch video resources through a projection curtain, and the isolation wall 2 plays a role in isolation and projection.
In still another embodiment of the present invention, the partition wall 1 is non-transparent, such as a non-transparent shielding plate, and one end of the partition wall 1 is rotatably connected to the vehicle body, so that the partition wall 1 can be kept perpendicular to the top or side wall of the vehicle body, or so that the partition wall 1 can be kept in contact with the top or side wall of the vehicle body. In this embodiment, when the partition wall 1 is perpendicular to the top or side wall of the vehicle body, it is used to block the line of sight between the front-row seats and the rear-row seats, with the partition wall 1 blocking between the front-row seats and the rear-row seats; when the partition wall 1 is attached to the top or side wall of the vehicle body, it is used to communicate the line of sight between the front-row seats and the rear-row seats, and the partition wall 1 is not located between the front-row seats and the rear-row seats. Alternatively, the switching between the attached state and the vertical state may be achieved by lifting, rotating the partition plate 1, or the like.
Alternatively, the partition wall 1 may also block or communicate the line of sight between the front row of seats and the rear row of seats in a lifting manner. For example, the partition wall 1 may be lifted or lowered along the back of the chair behind the front seat, and the partition wall 1 may include a first portion and a second portion, the first portion may be lifted with respect to the second portion, the second portion may be located at the bottom of the front seat, and the first portion may be flush with the second portion when lowered to the lowest position. When the first portion of the partition wall 1 is lifted from the lowest position to the highest position, the first portion and the second portion of the partition wall 1 together obstruct the line of sight between the front row of seats and the rear row of seats, and when the first portion of the partition wall 1 is lowered to the lowest position, the line of sight between the front row of seats and the rear row of seats is again communicated.
Alternatively, the partition wall 1 may have only a first portion, and no second portion, in this embodiment, the first portion may be raised or lowered along the back of the front seat, and when the first portion is raised from the lowest position to the highest position, the first portion and the back of the front seat block the line of sight between the front seat and the rear seat together, and when the first portion is lowered to the lowest position, the line of sight between the front seat and the rear seat is again communicated.
