In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

An in-vehicle light blocking device and a vehicle according to an embodiment of the present application will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an in-vehicle light blocking device according to an embodiment of the present application. The in-vehicle light blocking device is located inside a vehicle body, as shown in fig. 1, and includes:

the first connecting structure 1 is fixedly connected with the vehicle body, the first connecting structure 1 is specifically a long sliding rail, the first end of the long sliding rail is fixedly connected with a top cover of the vehicle body, and the second end of the long sliding rail is fixedly connected with the top cover or a wind window side edge;

a second connection structure 2 movably connected with the first connection structure 1;

a polarizer structure 3 provided on the second connection structure 2;

when the second connection structure 2 is in the first section of the first connection structure 1, the polarizer structure 3 is located below and parallel to the top cover; the first section is a sliding rail section taking the first end of the long sliding rail as a starting point and the first middle position point of the long sliding rail as an end point;

when the second connecting structure 2 is positioned in the second section of the first connecting structure 1, the polarizer structure 3 is parallel to the wind window corresponding to the wind window side edge, and performs polarized light filtering on the ambient light passing through the wind window, wherein the second section is a sliding rail section taking the second end of the long sliding rail as a starting point and the second middle position point of the long sliding rail as an end point;

the first section and the second section do not overlap.

It will be appreciated that the portion of the second connection structure 2 to which the first connection structure 1 is connected is shaped to mate with the long rail so as to enable the second connection structure 2 to move on the long rail, i.e. to achieve a movable connection of the second connection structure 2 to the first connection structure 1. Because the first connection structure 1 is fixed on the car body, and the second connection structure 2 can move the position at any time according to user's demand to adjust the position of the polarizer structure 3 on the second connection structure, and then realize carrying out polarized light filtering, namely shading to the ambient light that gets into the car body.

The light-transmitting part of the vehicle body comprises one or more of a front windshield, a side door window of the vehicle body and a rear windshield, the first connecting structure 1 can be fixed at a corresponding position on the vehicle body according to actual working conditions or requirements, and then the position adjustment of the polarizer structure 3 and the polarization filtering function of the polarizer structure 3 are utilized by the second connecting structure 2 to complete flexible shading of relevant positions.

It can be understood that, in this embodiment, the polarizer structure 3 is used for polarization filtering, most of light can be transmitted, that is, the transparency of the polarizer structure 3 is higher, and the view of the driver is not disturbed, so that the area of the polarizer structure 3 is significantly larger than that of the traditional sun visor, thereby realizing polarization filtering in a larger range, and covering the main view area which is not allowed to be blocked by the traditional sun visor. The traditional sunshading board is installed in the front windshield entablature of automobile body with fulcrum or the form of axle, and the sunshading board is direct to be broken off with the fingers and thumb down with fulcrum or the axle rotation can cover the light that front windshield sees through, considers that the area of polarizer structure 3 is obviously greater than traditional sunshading board in this embodiment, and polarizer structure 3 is thinner more easily damaged than the sunshading board, and the space of driver's cabin is insufficient to support polarizer structure 3 to follow the state transformation mode of traditional sunshading board, consequently sets up first connection structure 1 into the form of long slide rail in this embodiment: when the ambient light is softer and the user does not need the polarizer structure 3 to work, the polarizer structure 3 can be moved to other positions, such as a top cover, through the first connecting structure 1, and when the ambient light is dazzling and the user needs the polarizer structure 3, the polarizer structure 3 is slid to an area needing light blocking, such as a front windshield, through the first connecting structure 1. The car body wall can be pressed close to all the time to the polarizer structure 3 in the sliding process, the space of the cab is not occupied, high requirements on the space of the cab are not met, the light blocking device in the car is low in the existence sense of the inside of the car body, the deformation degree of the polarizer structure 3 is low, and meanwhile, the longer service life is guaranteed.

Furthermore, in this embodiment, the first connection structure 1 is used as a long sliding rail, and the specific position of the long sliding rail can be set according to the actual working condition or requirement, and the relative position and the fixing mode of the second connection structure 2 and the polarizer structure 3 can be further matched to perform relevant adjustment on the position of the long sliding rail. For example, the polarizer structure 3 is used for polarization filtering of ambient light passing through the front windshield, the polarizer structure is located near the top cover of the vehicle body when not working, at this time, a part of the starting point of the long sliding rail is necessarily located on the top cover of the vehicle body, a part of the second connecting structure 2 connected with the first connecting structure 1 is called an engagement piece 20, when the engagement piece 20 slides to the end point of the long sliding rail, the polarizer structure 3 should be capable of shielding the target shading area, so that a simpler scheme is that the starting point and the end point of the long sliding rail are both located on the top cover of the vehicle body, the plane of the long sliding rail in the vertical direction is kept parallel to the vertical direction of the vehicle body, and the end point is located on the top cover of the vehicle body at a first distance from the front windshield, as shown in fig. 2; however, in this solution, only one connecting piece 20 is used as a supporting point between the second connecting structure 2 and the first connecting structure 1, so that the position of the polarizer structure 3 is not easy to fix, and therefore, a plurality of connecting pieces 20 can be arranged on the second connecting structure 2 or the contact area between the connecting pieces 20 and the long sliding rail is larger, as shown in fig. 3, at this time, the supporting of the polarizer structure 3 by the plurality of connecting pieces 20 is more stable, but at this time, the contact area between the long sliding rail and the connecting pieces 20 needs to be extended to the target shading area, therefore, the starting point of the long sliding rail is located on the top cover of the vehicle body, the end point is located on the side edge of the front windshield, and the plane of the long sliding rail in the vertical direction is still kept parallel to the vertical direction of the vehicle body.

In the in-vehicle light blocking device disclosed by the embodiment of the application, the polarizer structure is polarization filtering, so that the interference of external glare rays is reduced, other external environments are not shielded, the field of view of a user is not reduced, the potential safety hazard of an original opaque sun shield is eliminated, meanwhile, the in-vehicle light blocking device is arranged in a vehicle body, the information of a display screen and an instrument panel is not influenced by the user to observe, the interference of the polarized light glasses on the display screen and the instrument panel is overcome, and the driving safety is ensured.

In some specific embodiments, the polarization filtering effect of the polarizer structure 3 may be adjusted by the polarization angle, so in this embodiment, the polarizer structure 3 of the light blocking device in the vehicle is configured to be a structure capable of adjusting the polarization angle, specifically, the second connecting structure 2 is provided with a sliding slot, and the polarizer structure 3 is provided with a sliding rail matched with the sliding slot, and the sliding rail is movably connected with the sliding slot and is used for adjusting the polarization angle of the polarizer structure 3. It can be understood that the sliding groove and the sliding rail are arc-shaped, and the polarizer structure 3 can be rotated by adjusting the relative positions of the sliding rail and the sliding rail, so that the adjustment of the polarization angle is realized.

In some specific embodiments, in consideration of the fact that the replacement, maintenance and temporary storage of the components are not applicable, the connection manner between the components in the in-vehicle light blocking device may be set to be detachably connected, and the polarizer structure 3 is detached from the vehicle body when the polarizer structure 3 needs to be temporarily stored or replaced, so that in the in-vehicle light blocking device, the second connection structure 2 is detachably connected with the polarizer structure 3, or the first connection structure 1 is detachably connected with the second connection structure 2.

It should be understood that, here, the polarizer structure 3 includes a polarizer body and a polarizer frame, the polarizer body is an optical lens covered with a polarizer and selectively passing light vibrating in a certain direction, the polarizer frame is a connection structure for fixing the polarizer body and connecting with other structures such as the second connection structure 2, and the slide rail is usually disposed on the polarizer frame.

In some embodiments, when the polarizer structure 3 works with a single-layer polarizer, the polarization filtering effect may not meet the user's requirement, so that a double-layer polarizer may be fixed on the second connection structure 2. Since the polarization angles of the two polarizers are perfectly perpendicular, which prevents all light from passing through, this must be avoided when a double polarizer is provided. Specifically, the polarizer structure 3 includes a first polarizer and a second polarizer; the first polarizer is connected with the second connecting structure, and the second polarizer is connected with the second connecting structure or the first polarizer;

the plane of the first polarizer and the plane of the second polarizer are parallel to each other;

the first polarization angle of the first polarizer and the second polarization angle of the second polarizer are not perpendicular.

At this time, there are various connection schemes, the first connection scheme is that the first polarizer and the second polarizer are respectively disposed on the second connection structure 2 in a plane-parallel positional relationship, and the second connection scheme is that the second polarizer is connected with the first polarizer to realize a plane-parallel positional relationship.

Further, in order to improve the adjustable flexibility of the polarization filtering, corresponding sliding grooves may be provided for the first polarizer and the second polarizer, respectively.

Specifically, taking the first connection scheme as an example, a first chute and a second chute are arranged on the second connection structure 2;

the first slide rail matched with the first slide groove is arranged on the first polarizer, and the first slide groove and the first slide rail can be connected in a matched mode and are used for adjusting the first polarization angle;

the second polarizer is provided with a second sliding rail matched with the second sliding groove, and the second sliding groove and the second sliding rail can be connected in a matched mode and are used for adjusting a second polarization angle.

Similarly, taking the second connection scheme as an example, a third sliding groove is arranged on the second connection device, a third sliding rail matched with the third sliding groove is arranged on the first polarizer, and the third sliding groove and the third sliding rail can be connected in a matched manner and are used for adjusting the first polarization angle;

the first polarizer is also provided with a fourth slide rail, the second polarizer is provided with a fourth slide rail matched with the fourth slide groove, and the fourth slide groove and the fourth slide rail can be connected in a matched manner and are used for adjusting the second polarization angle.

Or, in order to improve the adjustable flexibility of polarization filtering, a corresponding chute is only arranged on one polarizer, the other polarizer is kept at a fixed position, and especially when the second polarizer is connected to the first polarizer and the first polarizer is arranged on the second connecting structure 2, a fourth slide rail is only arranged on the second polarizer and a fourth chute matched with the fourth slide rail is arranged on the first polarizer. Thereby adjusting the relative polarization angle of the double-layer polarizer by adjusting the polarization angle of the single polarizer.

Further, in this embodiment, it is emphasized that the polarization angles of the first polarizer and the second polarizer cannot be perpendicular, otherwise, the driving safety is seriously affected by the light-tightness, so that even if a chute sliding rail for improving the adjustable flexibility is added, the situation that the polarization angle is perpendicular is avoided, for this embodiment, a corresponding foolproof structure is arranged on the light blocking device in the vehicle, and according to different specific connection modes of the double-layer polarizers, the foolproof structure is correspondingly changed.

Specifically, in the first connection mode, the light blocking device in the vehicle further includes:

the first fool-proof structure is positioned on the first sliding groove or the first sliding rail and is used for limiting the adjustment range of the first polarization angle to be (n-m, n is a preset angle, and m is a positive angle;

the second fool-proof structure is positioned on the second sliding groove or the second sliding rail and used for limiting the adjustment range of the second polarization angle to be [ n, n+k-m ], wherein k is the maximum relative polarization angle, and the maximum relative polarization angle is smaller than 90 degrees.

It will be appreciated that under the combined action of the first foolproof structure and the second foolproof structure, the relative polarization angles of the first polarizer and the second polarizer, i.e. the absolute difference between the first polarization angle and the second polarization angle, will not exceed k, but k <90 °, thereby ensuring that no complete light-tight event will occur.

Similarly, in the second connection mode, the in-vehicle light blocking device further includes:

the third fool-proof structure is positioned on the fourth sliding groove or the fourth sliding rail and is used for limiting the first polarization angle of the first polarizer and the second polarization angle of the second polarizer not to be perpendicular.

It is understood that the fourth slide groove and the fourth slide rail are only used for adjusting the relative polarization angles of the first polarization angle and the second polarization angle. Even if a sliding rail and a sliding groove are arranged between the first polarizer and the second connecting structure 2 to adjust the first polarization angle of the first polarizer, when the first polarization angle changes along with the rotation of the first polarizer, the second polarizer also rotates along with the rotation of the first polarizer, the second polarization angle also synchronously changes, and the relative polarization angle between the first polarization angle and the second polarization angle does not change.

It is to be understood that the above first fool-proof structure, second fool-proof structure and third fool-proof structure may be implemented by various forms of barriers, such as a closed chute or a sliding rail, providing a blocking block, etc., which are not particularly limited herein.

In some specific embodiments, referring to fig. 4, the light blocking device in the vehicle may further include a driving motor 4, where the driving motor 4 is disposed on the second connection structure 2, and receives a driving instruction of the controller to adjust a position of the polarizer structure 3, so as to implement an automatic or semi-automatic light blocking operation, where the semi-automatic driving instruction of the controller 5 is a driving instruction that is automatically generated by the controller 5 after the vehicle system receives a user instruction and then issued to the controller 5, and the automatic driving instruction is automatically generated by analyzing external ambient light. Specifically, in this case, the light blocking device further includes:

a controller 5 for analyzing ambient light from the image information and generating a driving instruction;

and a driving motor 4 arranged on the second connecting structure 2 and used for adjusting the position of the polarizer structure 3 according to the driving instruction.

It can be understood that, here, the image acquisition module 6 is not directly located at the driver's seat or at a position receiving the dazzling ambient light, the controller 5 will comprehensively determine whether the ambient light will interfere with the field of view of the user in the vehicle according to the image information acquired by the image acquisition module 6 located at each part of the vehicle and the current vehicle driving direction, geographic position, weather, current sunlight irradiation angle, and other factors, and if so, the corresponding driving instruction is generated again. The controller 5 analyzes the ambient light through the image information to generate a corresponding driving instruction to control the position of the polarizer structure 3, so that the intelligent degree of the intelligent cabin is further improved, and the user experience is greatly improved.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein. It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.

the first section and the second section do not overlap.

It will be appreciated that the portion of the second connecting structure to which the first connecting structure is connected is shaped to mate with the elongate rail so as to enable the second connecting structure to move on the elongate rail, i.e. to achieve a moveable connection of the second connecting structure to the first connecting structure. Because the first connection structure is fixed on the automobile body, and the second connection structure can move the position at any time according to user's demand to adjust the position of the polarizer structure on the second connection structure, and then realize carrying out polarized light filtering, namely shading to the ambient light that gets into the automobile body.

The light-transmitting part of the vehicle body comprises one or more of a front windshield, a side door window and a rear windshield, the first connecting structure can be fixed at a corresponding position on the vehicle body according to actual working conditions or requirements, and then the position of the polarizer structure is adjusted by the second connecting structure and the polarization filtering function of the polarizer structure is utilized to complete flexible shading of the relevant position.

It can be appreciated that, in this embodiment, the polarizer structure is used for polarization filtering, most of light can be transmitted, that is, the transparency of the polarizer structure is higher, and the view of the driver is not disturbed, so that the area of the polarizer structure is obviously larger than that of the traditional sun visor, thereby realizing polarization filtering in a larger range, and covering the main view area where the traditional sun visor is not allowed to block. Traditional sunshading board is installed in the front windshield entablature of automobile body with fulcrum or the form of axle, and the sunshading board is direct to break off with the fingers and thumb down with fulcrum or the axle rotation can cover the light that front windshield was transmitted, considers in this embodiment that the area of polarizer structure is obviously greater than traditional sunshading board, and the polarizer structure is thinner more easily damaged than the sunshading board, and the space of driver's cabin is insufficient to support the polarizer structure to follow the state change mode of traditional sunshading board, consequently this embodiment sets up the form of long slide rail with first connection structure: when the ambient light is softer and the user does not need the polarizer structure to work, the second connecting structure can be moved to the first section of the first connecting structure, so that the polarizer structure can be moved to other positions, such as a top cover, and when the ambient light is more dazzling and the user needs the polarizer structure, the second connecting structure can be moved to the second section of the first connecting structure, so that the polarizer structure can slide to an area needing light blocking, such as a front windshield. The vehicle body wall can be pressed close to all the time to the polarizer structure in the sliding process, the space of the cab is not occupied, high requirements on the space of the cab are not met, the light blocking device in the vehicle is low in sense of existence in the vehicle body, the deformation degree of the polarizer structure is low, and meanwhile, the longer service life is guaranteed.

For example, the polarizer structure is used for carrying out polarized light filtering on the ambient light passing through the front windshield, the polarizer structure is positioned near the top cover of the automobile body when not working, at the moment, the part of the starting point of the long sliding rail is necessarily positioned on the top cover of the automobile body, the part connected with the first connecting structure on the second connecting structure is called a connecting piece, and when the connecting piece slides to the end point of the long sliding rail, the polarizer structure can shade the target shading area, so that the starting point and the end point of the long sliding rail are positioned on the top cover of the automobile body, the plane of the long sliding rail in the vertical direction is kept parallel to the vertical direction of the automobile body, and the end point is positioned at the top cover of the automobile body along the first distance from the front windshield; however, in this scheme, only one connecting piece is used as a supporting point between the second connecting structure and the first connecting structure, so that the position of the polarizer structure is not easy to fix, a plurality of connecting pieces or a contact area between the connecting pieces and the long sliding rail can be arranged on the second connecting structure, at this time, the supporting of the polarizer structure by the plurality of connecting pieces is more stable, but at this time, the contact area between the long sliding rail and the connecting pieces needs to be extended to a target shading area, so that the starting point of the long sliding rail is positioned on the top cover of the automobile body, the end point is positioned on the side edge of the front windshield, and the plane of the long sliding rail in the vertical direction is still kept parallel to the vertical direction of the automobile body. The starting point of the long sliding rail is that the first end of the long sliding rail is positioned on the top cover of the automobile body, the terminal end is that the second end is positioned on the top cover or the side edge of the wind window of the automobile body, and the side edge of the wind window comprises one or more of the side edge of the front wind window, the side edge of the side door window of the automobile body and the side edge of the rear wind window.

Or, in order to improve the adjustable flexibility of polarization filtering, a corresponding chute is arranged on one polarizer, and the other polarizer is kept at a fixed position, especially when the second polarizer is connected to the first polarizer and the first polarizer is arranged on the second connecting structure, a fourth slide rail is arranged on the second polarizer only, and a fourth chute matched with the fourth slide rail is arranged on the first polarizer. Thereby adjusting the relative polarization angle of the double-layer polarizer by adjusting the polarization angle of the single polarizer.

Further, in this embodiment, it is emphasized that the polarization angles of the first polarizer and the second polarizer cannot be perpendicular, otherwise, the driving safety is seriously affected by the light-tightness, so that even if a chute sliding rail for improving the adjustable flexibility is added, the situation that the polarization angle is perpendicular is avoided, for this embodiment, a corresponding foolproof structure is arranged on the light blocking device in the vehicle, and according to different specific connection modes of the double-layer polarizers, the foolproof structure is correspondingly changed.

Specifically, in the first connection mode, the light blocking device in the vehicle further includes:

the first fool-proof structure is positioned on the first sliding groove or the first sliding rail and is used for limiting the adjustment range of the first polarization angle to be (n-m, n is a preset angle, and m is a positive angle;

the second fool-proof structure is positioned on the second sliding groove or the second sliding rail and used for limiting the adjustment range of the second polarization angle to be [ n, n+k-m ], wherein k is the maximum relative polarization angle, and the maximum relative polarization angle is smaller than 90 degrees.

It will be appreciated that under the combined action of the first foolproof structure and the second foolproof structure, the relative polarization angles of the first polarizer and the second polarizer, i.e. the absolute difference between the first polarization angle and the second polarization angle, will not exceed k, but k <90 °, thereby ensuring that no complete light-tight event will occur.

Similarly, in the second connection mode, the in-vehicle light blocking device further includes:

the third fool-proof structure is positioned on the fourth sliding groove or the fourth sliding rail and is used for limiting the first polarization angle of the first polarizer and the second polarization angle of the second polarizer not to be perpendicular.

It is understood that the fourth slide groove and the fourth slide rail are only used for adjusting the relative polarization angles of the first polarization angle and the second polarization angle. Even if a sliding rail and a sliding groove are arranged between the first polarizer and the second connecting structure to adjust the first polarization angle of the first polarizer, when the first polarization angle changes along with the rotation of the first polarizer, the second polarizer also rotates along with the rotation of the first polarizer, the second polarization angle also synchronously changes, and the relative polarization angle between the first polarization angle and the second polarization angle does not change.

It is to be understood that the above first fool-proof structure, second fool-proof structure and third fool-proof structure may be implemented by various forms of barriers, such as a closed chute or a sliding rail, providing a blocking block, etc., which are not particularly limited herein.

In some specific embodiments, the light blocking device in the vehicle may further include a driving motor, where the driving motor is disposed on the second connection structure, and receives a driving instruction of the controller to adjust a position of the polarizer structure, so as to implement automatic or semi-automatic light blocking operation, where the semi-automatic driving instruction of the controller is sent to the controller after the vehicle system receives a user instruction, and the automatic driving instruction is automatically generated by the controller after analyzing external ambient light. Specifically, in this case, the light blocking device further includes:

the image acquisition module is arranged on the vehicle body and is used for acquiring image information;

the controller is used for analyzing the ambient light according to the image information and generating a driving instruction;

and the driving motor is arranged on the second connecting structure and is used for adjusting the position of the polarizer structure according to the driving instruction.

It can be understood that the image acquisition module is not directly located at the driver seat or at the position for receiving the dazzling ambient light, and the controller comprehensively judges whether the ambient light can interfere with the field of view of the user in the vehicle according to the image information acquired by the image acquisition module located at each part of the vehicle and various factors such as the current vehicle running direction, the geographic position, the weather, the current sunlight irradiation angle and the like, and if so, the controller regenerates the corresponding driving instruction. The controller analyzes the ambient light through the image information to generate a corresponding driving instruction so as to control the position of the polarizer structure, so that the intelligent degree of the intelligent cabin is further improved, and the user experience is greatly improved.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein. It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
