Description

Vehicle privacy glass and vehicle Technical Field

[0001] The present invention relates to the technical field of vehicle glass, and in particular to vehicle privacy glass and a vehicle. Background Art

[0002] Currently, the glass used in cars is ordinary glass without sunshade function. Passengers will be troubled by the sun's radiation and can only reduce the invasion of ultraviolet rays by applying film. However, in order to ensure the light transmittance of the glass, it is impossible to completely block out light and there is no privacy function, so the car cannot become a private space.

[0003] The smart car privacy glass in the existing technology includes cavity glass and an internal car system. The internal car system includes a power supply and a car smart key system electrically connected to the power supply. The cavity glass is connected to a privacy glass that can move up and down through a lifting mechanism; a through groove is opened at the bottom of the cavity glass to allow the privacy glass to enter and exit; the privacy glass includes a first glass layer, a first adhesive layer, a dimming glass film, a second adhesive layer and a second glass layer; the power access end of the dimming glass film is connected to an inverter and is electrically connected to the power supply through the inverter; the dimming glass film is connected to the car smart key system signal through the inverter; the inverter is electrically connected to a knob control switch that controls the transparency of the dimming glass film; it can improve the flexibility of use; at the same time, the cavity glass can further improve the sound insulation and heat insulation effects.

[0004] Alternatively, a first glass layer, a color-changing glass layer, and a second glass layer are stacked in sequence, with the color-changing glass layer encapsulated between the first and second glass layers. The color-changing glass layer includes multiple pieces of electrochromic glass, which are arranged flatly and are all connected to a controller. The color-changing glass windshield utilizes multiple pieces of electrochromic glass arranged flatly and connected to a controller to achieve zoned adjustment of light transmittance, thereby meeting the light and temperature requirements of different passengers.

[0005] However, adjusting the light transmittance of the glass by moving the adhesive layer between the glass panes up and down results in a complex structure, a large Z-axis space, and insufficient privacy. Furthermore, the through-slot at the bottom of the cavity glass is not sealed, preventing moisture from escaping. Adjusting light by changing color doesn't provide complete sunlight shielding or privacy.

[0006] Summary of the Invention

[0007] In response to the defects in the prior art, the purpose of the present invention is to provide a vehicle privacy glass and a vehicle, which can solve the problem in the prior art that the transmittance of the glass is adjusted by moving the glue layer added between the glass up and down, resulting in the structure of the entire privacy glass being complex, occupying a large Z-direction space, and not being concealed enough.

[0008] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0009] In one aspect, the present invention provides a vehicle privacy glass, comprising:

The drive member is connected to the reel and is configured to drive the end of the reel connected to the curtain support rod to move between the two layers of glass, so as to drive the blackout curtain to unfold or retract between the two layers of glass.

[0013] In some optional schemes, the driving assembly also includes a slide groove, which is arranged along the unfolding direction of the blackout curtain and is located on one side of the blackout curtain. One end of the roller is connected to the curtain support rod and slides in the slide groove along the unfolding direction of the blackout curtain.

[0014] In some optional solutions, a slider matching the shape of the slide groove is provided at one end of the winding shaft connected to the curtain support rod, and the winding shaft is connected to the curtain support rod via the slider.

[0015] In some optional solutions, a roller is provided at one end of the winding shaft connected to the curtain support rod. The roller is clamped in the slide groove and can roll in the slide groove along the unfolding direction of the blackout curtain.

[0016] In some optional solutions, the slot opening of the slide groove faces the blackout curtain, a limiting protrusion is provided at the bottom of the slide groove, and a limiting groove corresponding to the limiting protrusion is provided in the circumferential direction of the roller profile.

[0017] In some optional schemes, an expansion limit groove is provided between the two glass layers, which is provided at the expansion limit position of the expansion end of the blackout curtain when it is expanded. The expansion limit groove and the curtain support rod are made of magnetic materials that attract each other.

[0018] In some optional schemes, a folding limiter is provided between the two glass layers, which is provided at the folding limit position of the unfolded end of the shading curtain when folded, and the folding limiter and the curtain support rod are made of magnetic materials that attract each other.

[0019] In some optional schemes, the folding limit member includes two limit rods, which are fixed relative to the two layers of glass and have a gap for the blackout curtain to pass through. When the blackout curtain is folded, the curtain support rod is clamped on the two limit rods.

[0020] In some optional schemes, the expansion limit slot and the folding limit member use electromagnets. When the blackout curtain is expanded, the expansion limit slot is powered on and the folding limit member is powered off. When the blackout curtain is folded, the expansion limit slot is powered off and the folding limit member is powered on.

[0021] In some optional schemes, the curtain support rod includes two clamping rods, the blackout curtain is located between the two clamping rods, one of the clamping rods is provided with a protrusion on the side close to the blackout curtain, and the other clamping rod is provided with a limiting hole corresponding to the protrusion, and the protrusion passes through the blackout curtain and is clamped in the limiting hole.

[0022] In some optional solutions, the curtain fixing rod is provided at the other end of the blackout curtain, and is located between the two glass layers and fixed relative to the glass layers.

[0023] In some optional solutions, the blackout curtain fabric is folded in a fan shape when folded.

[0024] In some optional solutions, the hardness of the blackout curtain fabric at the folding crease is less than the hardness of the area between the two folding creases.

[0025] In some optional solutions, curtain support ribs are provided at the folding creases of the blackout curtain.

[0026] In some optional schemes, the driving member is a motor, the driving shaft of the motor passes through the two layers of glass and is clamped with the winding shaft between the two layers of glass, and one end of the driving shaft passing through the two layers of glass is provided with a motor mounting bolt.

[0027] In some optional solutions, a sealing layer is provided at the edge between the two glass layers.

[0028] In some optional solutions, sealing gaskets are provided between the motor and the glass layer, and between the glass layer and the motor mounting bolts.

[0029] On the other hand, the present invention further provides a vehicle comprising any of the above-mentioned privacy glass for vehicles.

[0030] Compared with the prior art, the advantages of the present invention are as follows: the reeling force of the reel is released by rotating the driving member, and the reel slowly extends, so that the end of the reel connected to the curtain support rod moves between the two layers of glass, thereby driving the curtain support rod to move between the two layers of glass in the direction of unfolding the blackout curtain, thereby driving the blackout curtain to unfold between the two layers of glass. When the blackout curtain needs to be retracted, the reeling force of the driving member is overcome by rotating the reel, and the reel slowly retracts, so that the end of the reel connected to the curtain support rod moves between the two layers of glass, thereby driving the curtain support rod to move between the two layers of glass in the direction of folding the blackout curtain, thereby driving the blackout curtain to fold between the two layers of glass. In this solution, the reel is arranged between the two layers of glass, and the curtain support rod connected thereto is used to drive the blackout curtain to move between the two layers of glass, so that the mechanism is concealed, does not occupy space, and does not affect the normal assembly of the glass. The two layers of glass set at intervals are installed on the glass lifter like regular glass. Since the design of the privacy curtain is all concentrated inside the privacy glass, it does not affect its installation layout. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0045] As shown in FIG. 1 to FIG. 8 , on the one hand, the present invention provides a privacy glass for a vehicle, comprising: a shading component 2 , a driving component 3 and two glass layers 1 spaced apart.

[0046] The shading assembly 2 includes a shade curtain 21 and a curtain support rod 22. The shade curtain 21 is arranged between the two layers of glass 1, and the curtain support rod 22 is arranged at one end of the shade curtain 21. The driving assembly 3 includes a reel 31 and a driving member 32. The reel 31 is arranged between the two layers of glass 1, and one end of the reel 31 is connected to the curtain support rod 22. The driving member 32 is connected to the reel 31 and is configured to drive the end of the reel 31 connected to the curtain support rod 22 to move between the two layers of glass 1, thereby driving the shade curtain 21 to expand or retract between the two layers of glass 1.

[0047] When the vehicle privacy glass needs to be used to open the blackout curtain 21, the driving member 32 is rotated to release the retraction force of the reel 31, and the reel 31 is slowly extended, so that the end of the reel 31 connected to the curtain support rod 22 moves between the two layers of glass 1, thereby driving the curtain support rod 22 to move between the two layers of glass 1 in the direction of unfolding the blackout curtain 21, thereby driving the blackout curtain 21 to unfold between the two layers of glass 1. When the blackout curtain 21 needs to be retracted, the driving member 32 is rotated to overcome the retraction force of the reel 31, and the reel 31 is slowly retracted, so that the end of the reel 31 connected to the curtain support rod 22 moves between the two layers of glass 1, thereby driving the curtain support rod 22 to move between the two layers of glass 1 in the direction of retracting the blackout curtain 21, thereby driving the blackout curtain 21 to retract between the two layers of glass 1. In this solution, the shading curtain 21 is driven to move between the two layers of glass 1 by a reel 31 arranged between the two layers of glass 1 and a curtain support rod 22 connected thereto, so that the mechanism is concealed, does not take up space, and does not affect the normal assembly of the glass.

[0048] In this example, the reel 31 is a retractable rod-shaped member, which is in the shape of a rod when unfolded and in the shape of a tape measure when retracted.

[0049] In addition, in this solution, when one end of the roller 31 connected to the curtain support rod 22 moves between the two layers of glass 1, it is arranged in the vertical direction, located on one side of the blackout curtain 21, and located in the main structure of the car door. The driving member 32 is also located in the window frame or the main structure of the car door. When in use, only the blackout curtain 21 will be seen expanding or contracting in the hole of the car door window frame.

[0050] As shown in Figures 2, 3, 4, 7 and 8, in some optional embodiments, the drive assembly 3 also includes a slide groove 33, which is arranged along the unfolding direction of the blackout curtain 21 and is located on one side of the blackout curtain 21. One end of the roller 31 is connected to the curtain support rod 22 and slides in the slide groove 33 along the unfolding direction of the blackout curtain 21.

[0051] In this embodiment, the slide groove 33 is located within the main structure of the vehicle door and is obscured by the main structure, thus not affecting the appearance of the vehicle window. A slide groove 33 is provided on one side of the blackout curtain 21, extending along the direction of deployment of the blackout curtain 21. This groove limits the position of the end of the reel 31 connected to the curtain support rod 22 when the end moves between the two layers of glass 1, thereby ensuring greater stability for the curtain support rod 22 as it moves between the two layers of glass 1.

[0052] In this example, the slide groove 33 is arranged vertically. When the blackout curtain 21 is unfolded, the blackout curtain 21 moves upward against the curtain support rod 22 under the pushing force of the winding shaft 31, and is unfolded in the vertical direction under the push of the curtain support rod 22. When the blackout curtain 21 is retracted, the curtain support rod 22 is pulled by the winding shaft 31, the curtain support rod 22 moves downward, and the blackout curtain 21 is retracted under the action of gravity.

[0053] In other embodiments, the slide groove 33 can also be set horizontally. When the blackout curtain 21 is unfolded, the blackout curtain 21 moves against the curtain support rod 22 under the pushing force of the winding shaft 31, and is unfolded in the horizontal direction under the push of the curtain support rod 22; when the blackout curtain 21 is retracted, a winding shaft can be set at the other end of the blackout curtain 21 and equipped with a winding spring. When retracting, the curtain support rod 22 is pulled by the winding shaft 31, the curtain support rod 22 moves horizontally, the winding spring provides a retracting force, and the winding shaft retracts the blackout curtain 21.

[0054] As shown in Figures 3, 4 and 9, in some optional embodiments, a slider 311 matching the shape of the slide groove 33 is provided at one end of the reel 31 connected to the curtain support rod 22, and the reel 31 is connected to the curtain support rod 22 through the slider 311.

[0055] In this embodiment, generally, since the window generally has only one side with a regular vertical shape in the direction of the vehicle length, it is possible to set the slide groove 33 vertically and it can be hidden in the door body 41. Therefore, the curtain support rod 22 is perpendicular to the moving direction of the end of the reel 31, and the reel 31 needs to be able to be rolled up when the blackout curtain 21 is folded. The rigidity of the reel 31 cannot be too strong. If the curtain support rod 22 is simply supported by the extended reel 31, the curtain support rod 22 may be tilted, thereby affecting the appearance of the blackout curtain 21 when it is unfolded. In this solution, a slider 311 matching the shape of the slide groove 33 is provided at one end of the connecting shaft 31 and the curtain support rod 22, and the slider 311 is clamped in the slide groove 33. The function of the winding shaft 31 is mainly to push the slider 311 to move in the slide groove 33, and basically does not participate in the lateral support of the curtain support rod 22. The task of lateral support of the curtain support rod 22 is mainly undertaken by the slider 311. Since the slider 311 matches the shape of the slide groove 33 and is clamped in the slide groove 33, the slider 311 can provide force to laterally support the curtain support rod 22.

[0056] Furthermore, in this example, the cross-section of the sliding cavity in the chute 33, in which the slider 311 is mounted, is arc-shaped. The cross-section of the slider 311 is also arc-shaped. The opening of the sliding cavity faces the shade curtain 21. The curtain support rod 22 passes through the opening of the sliding cavity and is connected to the slider 311 in the sliding cavity. In other embodiments, the cross-section of the sliding cavity in which the slider 311 is mounted in the chute 33 can also be rectangular, so as to provide a force that can retain the slider 311 in the chute 33 and support the curtain support rod 22.

[0057] As shown in Figures 3, 4 and 10, in some optional embodiments, a roller 312 is provided at one end of the reel 31 connected to the curtain support rod 22. The roller 312 is clamped in the slide groove 33 and can roll in the slide groove 33 along the unfolding direction of the blackout curtain 21.

[0058] In this embodiment, a roller 312 is provided at the end of the reel 31 connected to the curtain support rod 22. This facilitates movement of the reel 31 within the chute 33, reducing friction. Because the reel 31 needs to be able to be retracted when the shade curtain 21 is retracted, the reel 31 must be rigid. Therefore, the roller 312 is provided at the end of the reel 31 connected to the curtain support rod 22 to reduce friction between the reel 31 and the chute 33, thereby reducing the rigidity requirement for the reel 31 to a certain extent.

[0059] In this example, a bracket 313 is provided at one end of the reel 31 connected to the curtain support rod 22 , and the roller 312 is rotatably arranged in the bracket 313 through a pin shaft. The bracket 313 is connected to the curtain support rod 22 and is clamped in the slide groove 33 .

[0060] As shown in FIG10 , in some optional embodiments, the slot opening of the slide groove 33 faces the shade curtain 21 , a limiting protrusion is provided at the bottom of the slide groove 33 , and a limiting groove corresponding to the limiting protrusion is provided in the circumferential direction of the contour of the roller 312 .

[0061] In this embodiment, the radial surface of the roller 312 at its center is coplanar with the axis of the curtain support rod 22. The curtain support rod 22 is connected to the bracket 313 through the notch of the chute 33. A stopper protrusion is provided at the bottom of the chute 33, and a stopper groove corresponding to the stopper protrusion is provided circumferentially along the profile of the roller 312. This position of the roller 312 is controlled as it moves within the chute 33, thereby maintaining the stability of the curtain support rod 22 during movement and enhancing the quality of the product. In this embodiment, the stopper groove is located in the center of the roller 312, and the cross-sectional shapes of the stopper groove and the stopper protrusion are matching arcs.

[0062] As shown in Figure 8, in some optional embodiments, an expansion limit groove 11 is further provided between the two glass layers 1, which is provided at the expansion limit position of the expansion end of the blackout curtain 21 when it is expanded. The expansion limit groove 11 and the curtain support rod 22 are made of magnetic materials that attract each other.

[0063] In this embodiment, the slide groove 33 is arranged vertically, and the curtain support rod 22 moves in the vertical direction, thereby expanding or contracting the shade curtain 21 in the vertical direction. When the shade curtain 21 is expanded and the extended end of the shade curtain 21 is at the extended limit position, relying solely on the curtain support rod 22 to support the entire shade curtain 21 for a long time may cause the curtain support rod 22 to bend, affecting the effect of the shade curtain 21 within the window, for example, causing the curtain support rod 22 to partially leak into the window. Under normal circumstances, when the extended end of the shade curtain 21 is at the extended limit position, the curtain support rod 22 is hidden within the sealing ring on the outer edge of the door body 41 or the window 42. In this example, when the blackout curtain 21 is deployed, a deployment limit slot 11 is provided at the deployed end of the blackout curtain 21 at its deployment limit position. Furthermore, the deployment limit slot 11 and the curtain support rod 22 are made of mutually attractive magnetic materials. This allows the curtain support rod 22 to be magnetically attracted to the deployment limit slot 11 when it moves to the deployment limit slot 11. The magnetic attraction of the deployment limit slot 11 provides a certain amount of support for the curtain support rod 22, preventing the curtain support rod 22 from shaking due to bumps during vehicle driving. Furthermore, the deployment limit slot 11 also provides a limit for the curtain support rod 22 at its maximum upward position, preventing it from colliding with the sealing layer located between the two layers of glass 1 and at the edge, thereby damaging the seal between the two layers of glass 1.

[0064] In this example, the shade curtain 21 is extended or retracted vertically, with the extended limit position located at the topmost edge of the two glass layers 1. In other embodiments, the extended limit position can be set based on the actual extension or retraction direction of the shade curtain 21. The extension limit groove 11 is fixedly disposed between the two glass layers 1 and located at the topmost edge of the two glass layers 1. The extended end of the shade curtain 21 refers to the end of the shade curtain 21 where the curtain support rod 22 is located.

[0065] As shown in Figures 5 to 7, in some optional embodiments, a folding limit member 12 is further provided between the two glass layers 1, which is arranged at the folding limit position of the unfolded end of the shading curtain 21 when folded, and the folding limit member 12 and the curtain support rod 22 are made of magnetic materials that attract each other.

[0066] In this embodiment, when the shade curtain 21 is retracted and the extended end of the shade curtain 21 is at the retracted limit position, the retracted limit position is located at the outer edge of the window, where the door body can just hide the curtain support rod 22. In this solution, in order to facilitate the easy opening of the shade curtain 21 when it is extended, the retracted limit position is not the position where the curtain support rod 22 compacts the shade curtain 21. That is, there is a certain gap between the shade curtain 21 at the retracted limit position and the other end where the curtain is fixed, allowing the shade curtain 21 to be partially extended. If the shade curtain 21 is supported solely by the curtain support rod 22 for a long time, the curtain support rod 22 may also bend, affecting the effect of the shade curtain 21 in the window when it is extended next time, for example, the curtain support rod 22 may partially leak into the window. Under normal circumstances, when the unfolded end of the blackout curtain 21 is located at the unfolding limit position, the curtain support rod 22 is hidden in the sealing ring of the door body 41 or the outer edge of the window 42.

[0067] In this example, when the shade curtain 21 is retracted, a retraction stopper 12 is provided at the extended end of the shade curtain 21 at its extreme retraction position. Furthermore, the retraction stopper 12 and the shade support rod 22 are made of mutually attractive magnetic materials. This allows the shade support rod 22 to be magnetically attracted to the retraction stopper 12 when it moves to the retraction stopper 12. The magnetic attraction of the retraction stopper 12 provides a certain amount of support for the shade support rod 22, preventing the shade support rod 22 from shaking due to bumps during vehicle travel. Furthermore, the retraction stopper 12 also limits the shade support rod 22's downward movement, preventing it from compacting the shade curtain 21 retracted between the two glass layers 1 and hindering its subsequent deployment.

[0068] As shown in Figures 5 and 6, in some optional embodiments, the folding limit member 12 includes two limit rods 121, which are fixed relative to the two layers of glass 1 respectively, and leave a gap for the blackout curtain 21 to pass through. When the blackout curtain 21 is folded, the curtain support rod 22 is clamped on the two limit rods 121.

[0069] In this embodiment, when the blackout curtain 21 is folded, two limit rods 121 are set at the folding limit position of the unfolded end of the blackout curtain 21, and the two limit rods 121 are fixed relative to the two layers of glass 1 respectively, and a gap is left between the two limit rods 121 for the blackout curtain 21 to pass through. When the blackout curtain 21 is folded, the curtain support rod 22 is clamped on the two limit rods 121, that is, in this solution, the limit rod 121 and the curtain support rod 22 are made of magnetic materials that attract each other, and the gap between the two limit rods 121 is greater than the width of the curtain support rod 22, so as to prevent the curtain support rod 22 from falling from between the two limit rods 121, that is, it can support the curtain support rod 22, limit the relative position of the curtain support rod 22, and limit the lowering limit position of the curtain support rod 22.

[0070] In addition, the driving force of the driving member 32 driving the winding shaft 31 connected to the curtain support rod 22 to move between the two layers of glass 1 is greater than the magnetic attraction between the retraction limiter 12 and the curtain support rod 22 and the curtain support rod 22 and the limit rod 121.

[0071] In some optional embodiments, the expansion limit slot 11 and the folding limit member 12 use electromagnets. When the blackout curtain 21 is expanded, the expansion limit slot 11 is powered on and the folding limit member 12 is powered off. When the blackout curtain 21 is folded, the expansion limit slot 11 is powered off and the folding limit member 12 is powered on.

[0072] In this embodiment, the curtain support rod 22 is made of a special material. When the shade curtain 21 is deployed, the retraction stopper 12 is powered off, eliminating the magnetic force of the retraction stopper 12. The curtain support rod 22 does not need to overcome the magnetic force of the retraction stopper 12 when moving upward, only needing to overcome gravity. This prevents deformation of the curtain support rod 22. After the shade curtain 21 is fully deployed, the deployment stopper 11 is powered on, causing the curtain support rod 22 and the deployment stopper 11 to attract each other, providing support for the curtain support rod 22. When the shade curtain 21 is retracted, the deployment stopper 11 is powered off, eliminating the magnetic force. The curtain support rod 22 does not need to overcome the magnetic force of the deployment stopper 11 when moving downward. After the shade curtain 21 is fully deployed, the retraction stopper 12 is powered on, causing the curtain support rod 22 and the retraction stopper 12 to attract each other, maintaining the relative position of the curtain support rod 22.

[0073] In some optional embodiments, the curtain support rod 22 includes two clamping rods, and the blackout curtain 21 is located between the two clamping rods. One of the clamping rods is provided with a protrusion on the side close to the blackout curtain 21, and the other clamping rod is provided with a limiting hole corresponding to the protrusion, and the protrusion passes through the blackout curtain 21 and is clamped in the limiting hole.

[0074] In this embodiment, the curtain support rod 22 has a two-piece structure, that is, it includes two clamping rods. A protrusion is provided on one side of the clamping rod near the blackout curtain 21. The protrusion is passed through the blackout curtain 21 and is clamped into a retaining hole provided on the other clamping rod corresponding to the protrusion. This method facilitates the installation of the blackout curtain 21 on the curtain support rod 22 and provides relatively stable support for the blackout curtain 21. In other embodiments, the curtain support rod 22 can also be designed with other structures, as long as it can support the blackout curtain 21.

[0075] In some optional embodiments, a curtain fixing rod 24 is provided at the other end of the shading curtain 21 , and is located between the two glass layers 1 and fixed relative to the glass layer 1 .

[0076] In this embodiment, the shade curtain 21 includes an extended end and a fixed end. The extended end is connected to a curtain support rod 22 and is located above the window, while the fixed end is fixed relative to the two layers of glass 1. In this embodiment, a curtain fixing rod 24 is used to secure the shade curtain 21 relative to the two layers of glass 1. This rod is located at the other end of the shade curtain 21, i.e., the fixed end, thereby securing the shade curtain 21. In this embodiment, the shade curtain 21 can be extended or retracted vertically. When retracting, the shade curtain 21 retracts automatically due to gravity.

[0077] In other embodiments, a reel may be provided at the fixed end of the blackout curtain 21 and equipped with a winding spring. When the curtain is folded, the curtain support rod 22 is pulled by the reel 31, the curtain support rod 22 moves laterally, the winding spring provides a winding force, and the reel reels the blackout curtain 21, thereby realizing the lateral expansion and folding of the blackout curtain 21.

[0078] In some optional embodiments, the blackout curtain fabric 21 is folded in a fan shape when folded.

[0079] In this embodiment, the blackout curtain 21 is folded in a fan shape when folded, and is flat when opened. This design facilitates the blackout curtain 21 to automatically fold when folded.

[0080] In some optional embodiments, the hardness of the blackout curtain fabric 21 at the folding crease is less than the hardness of the area between the two folding creases.

[0081] In this embodiment, the hardness of the folding crease is less than that of the area between the two folding creases, which facilitates automatic folding of the blackout curtain 21 when it is folded. In addition, the width of the folded sheet between the two folding creases is less than or equal to the width between the two layers of glass 1. When one folded sheet falls, its edge is located inside one of the layers of glass 1. The next folded sheet can only bend toward the area between the two layers of glass 1. This reciprocating process completes the folding of all folded sheets.

[0082] In some optional embodiments, a curtain supporting rib 23 is provided at the folding crease of the blackout curtain 21 .

[0083] In this embodiment, curtain support ribs 23 are provided at the folding crease to provide certain support to the blackout curtain 21. Since the window is irregular in this solution, one side of the blackout curtain 21 in the direction of expansion and contraction is vertically provided, and the other side is irregular. The width of the middle part of the window is greater than the width of the upper part. Only a roller 31 can be provided at one end of the curtain support rod 22 to drive the curtain support rod 22 to move between the two layers of glass 1. Then the width of the middle blackout curtain 21 is also greater than the width of the upper blackout curtain 21. Therefore, curtain support ribs 23 are provided at the folding crease to provide certain support to the middle part of the blackout curtain 21 to maintain a flat shape. In addition, the blackout curtain 21 is also made of a material with a certain hardness.

[0084] In some optional embodiments, the driving member 32 is a motor, the driving shaft of the motor passes through the two glass layers 1 and is clamped to the winding shaft 31 between the two glass layers 1. One end of the driving shaft passing through the two glass layers 1 is provided with a motor mounting bolt 35.

[0085] In this embodiment, the reel 31 is rod-shaped when unrolled, with one end connected to the curtain support rod 22 and the other end engaging the motor drive shaft that passes through the two layers of glass 1. The motor drives the motor drive shaft to rotate, thereby driving the reel 31 to reel or unwind. Furthermore, a motor mounting bolt 35 is provided at one end of the drive shaft that passes through the two layers of glass 1. The motor drive shaft and the motor mounting bolt 35 are engaged and can rotate relative to each other to prevent the motor from falling off.

[0086] In some optional embodiments, a sealing layer 13 is provided at the edge between the two glass layers 1 .

[0087] In this embodiment, a sealing layer 13 is provided at the edge between the two glass layers 1 to seal the space between the two glass layers 1 as a whole, thereby ensuring the dryness of the interior of the double-layer glass and preventing fogging.

[0088] In some optional embodiments, sealing gaskets 34 are provided between the motor and the glass layer 1 , and between the glass layer 1 and the motor mounting bolts 35 .

[0089] In this embodiment, sealing gaskets 34 are provided between the motor and the glass layer 1 , and between the glass layer 1 and the motor mounting bolts 35 , to ensure the sealing inside the double-layer glass and prevent the entry of external gas.

[0090] The present invention also provides a vehicle, comprising: any one of the above-mentioned vehicle privacy glass.

[0091] When the vehicle privacy glass needs to be used to open the blackout curtain 21, the driving member 32 is rotated to release the retraction force of the reel 31, and the reel 31 is slowly extended, so that the end of the reel 31 connected to the curtain support rod 22 moves between the two layers of glass 1, thereby driving the curtain support rod 22 to move between the two layers of glass 1 in the direction of unfolding the blackout curtain 21, thereby driving the blackout curtain 21 to unfold between the two layers of glass 1. When the blackout curtain 21 needs to be retracted, the driving member 32 is rotated to overcome the retraction force of the reel 31, and the reel 31 is slowly retracted, so that the end of the reel 31 connected to the curtain support rod 22 moves between the two layers of glass 1, thereby driving the curtain support rod 22 to move between the two layers of glass 1 in the direction of retracting the blackout curtain 21, thereby driving the blackout curtain 21 to retract between the two layers of glass 1. In this solution, the shading curtain 21 is driven to move between the two layers of glass 1 by a reel 31 arranged between the two layers of glass 1 and a curtain support rod 22 connected thereto, so that the mechanism is concealed, does not take up space, and does not affect the normal assembly of the glass.

[0092] The slide groove 33 is positioned within the main structure of the vehicle door and is concealed by the main structure, thereby not affecting the appearance of the vehicle window. A slide groove 33 is provided on one side of the blackout curtain 21, extending along the direction of deployment of the blackout curtain 21. This groove limits the position of the connecting end of the reel 31 and the curtain support rod 22 when the reel 31 moves between the two layers of glass 1, thereby ensuring greater stability for the curtain support rod 22 as it moves between the two layers of glass 1.

[0093] The slide groove 33 is arranged vertically. When the blackout curtain 21 is unfolded, the blackout curtain 21 moves upward against the curtain support rod 22 under the pushing force of the winding shaft 31, and is unfolded in the vertical direction under the push of the curtain support rod 22. When the blackout curtain 21 is retracted, the curtain support rod 22 is pulled by the winding shaft 31, the curtain support rod 22 moves downward, and the blackout curtain 21 is retracted under the action of gravity.

[0094] Since the window generally has only one side with a regular vertical shape in the direction of the vehicle length, it is possible to set the slide groove 33 vertically and hide it in the door body 41. Therefore, the curtain support rod 22 is perpendicular to the moving direction of the end of the reel 31, and the reel 31 needs to be able to be rolled up when the blackout curtain 21 is folded. The rigidity of the reel 31 cannot be too strong. If the curtain support rod 22 is simply supported by the extended reel 31, the curtain support rod 22 may be tilted, thereby affecting the appearance of the blackout curtain 21 when it is unfolded. In this solution, a slider 311 matching the shape of the slide groove 33 is provided at one end of the connecting shaft 31 and the curtain support rod 22, and the slider 311 is clamped in the slide groove 33. The function of the winding shaft 31 is mainly to push the slider 311 to move in the slide groove 33, and basically does not participate in the lateral support of the curtain support rod 22. The task of lateral support of the curtain support rod 22 is mainly undertaken by the slider 311. Since the slider 311 matches the shape of the slide groove 33 and is clamped in the slide groove 33, the slider 311 can provide force to laterally support the curtain support rod 22.

[0095] A roller 312 is provided at the end of the reel 31 connected to the curtain support rod 22 to facilitate movement of the reel 31 within the chute 33, reducing friction. Because the reel 31 needs to be able to be retracted when the shade curtain 21 is retracted, the reel 31 cannot be too rigid. Therefore, the roller 312 is provided at the end of the reel 31 connected to the curtain support rod 22 to reduce friction between the reel 31 and the chute 33, thereby reducing the rigidity requirement for the reel 31 to a certain extent.

[0096] The radial surface of the roller 312 at its center is coplanar with the axis of the curtain support rod 22. The curtain support rod 22 connects to the bracket 313 through the notch of the chute 33. A stopper protrusion is provided at the bottom of the chute 33, and a stopper groove corresponding to the stopper protrusion is provided circumferentially along the profile of the roller 312. This helps to control the position of the roller 312 as it moves within the chute 33, thereby maintaining the stability of the curtain support rod 22 during movement and enhancing the quality of the product. In this example, the stopper groove is located in the center of the roller 312, and the cross-sectional shapes of the stopper groove and the stopper protrusion are matching arcs.

[0097] The slide groove 33 is arranged vertically, and the curtain support rod 22 moves in the vertical direction, causing the shade curtain 21 to expand or retract in the vertical direction. When the shade curtain 21 is expanded and the extended end of the shade curtain 21 is at the extended limit position, relying solely on the curtain support rod 22 to support the entire shade curtain 21 for a long time may cause the curtain support rod 22 to bend, affecting the effect of the shade curtain 21 within the window, for example, causing the curtain support rod 22 to partially leak into the window. Under normal circumstances, when the extended end of the shade curtain 21 is at the extended limit position, the curtain support rod 22 is hidden within the sealing ring on the outer edge of the door body 41 or the window 42. In this example, when the blackout curtain 21 is deployed, a deployment limit slot 11 is provided at the extended end of the blackout curtain 21, where it reaches its limit of deployment. Furthermore, the deployment limit slot 11 and the curtain support rod 22 are made of mutually attractive magnetic materials. This allows the curtain support rod 22 to be magnetically attracted to the deployment limit slot 11 when it moves to the deployment limit slot 11. The magnetic attraction of the deployment limit slot 11 provides a certain degree of support for the curtain support rod 22, preventing it from shaking due to bumps during vehicle travel. Furthermore, the deployment limit slot 11 also limits the curtain support rod 22's upward movement, preventing it from striking the sealing layer located between the two glass layers 1 and at the edge, potentially damaging the seal between the two glass layers 1.

[0098] To facilitate the opening of the shade curtain 21 during deployment, the curtain support rod 22 does not compress the shade curtain 21 at its maximum retraction position. This means that a gap exists between the shade curtain 21 at its maximum retraction position and the other end where the curtain is fixed, allowing the shade curtain 21 to partially unfold. If the shade curtain 21 were solely supported by the curtain support rod 22, and if this were to be supported for an extended period, the curtain support rod 22 could also bend, affecting the shade curtain 21's performance within the window the next time it is deployed, for example, causing the curtain support rod 22 to partially leak into the window. Under normal circumstances, when the shade curtain 21's deployed end is at its maximum retraction position, the curtain support rod 22 is concealed within the sealing ring on the door body 41 or the outer edge of the window 42.

[0099] When the blackout curtain 21 is folded, two limit rods 121 are set at the folding limit position of the unfolded end of the blackout curtain 21, and the two limit rods 121 are fixed relative to the two layers of glass 1 respectively, and a gap is left between the two limit rods 121 for the blackout curtain 21 to pass through. When the blackout curtain 21 is folded, the curtain support rod 22 is clamped on the two limit rods 121, that is, in this solution, the limit rod 121 and the curtain support rod 22 are made of magnetic materials that attract each other, and the gap between the two limit rods 121 is greater than the width of the curtain support rod 22, so as to prevent the curtain support rod 22 from falling from between the two limit rods 121, that is, it can support the curtain support rod 22, limit the relative position of the curtain support rod 22, and limit the lowering limit position of the curtain support rod 22.

[0100] The curtain support rod 22 has a two-piece structure, comprising two clamping rods. A protrusion is provided on one side of the clamping rod near the shade curtain 21. The protrusion is passed through the shade curtain 21 and is secured within a corresponding retaining hole provided on the other clamping rod. This arrangement facilitates the installation of the shade curtain 21 onto the curtain support rod 22 and provides relatively stable support for the shade curtain 21. In other embodiments, the curtain support rod 22 may be designed with other structures, as long as they can support the shade curtain 21.

[0101] The hardness of the folding crease is less than that of the area between the two folding creases, which facilitates the automatic folding of the blackout curtain 21 when it is folded. In addition, the width of the folding sheet between the two folding creases is less than or equal to the width between the two layers of glass 1. When one folding sheet falls, its edge is located inside one of the layers of glass 1. The next folding sheet can only bend toward the area between the two layers of glass 1. This reciprocating process completes the folding of all folding sheets.

[0102] Curtain support ribs 23 are provided at the folding crease to provide certain support to the blackout curtain 21. Since the window is irregular in this solution, one side of the blackout curtain 21 in the direction of expansion and contraction is vertically arranged, and the other side is irregular. The width of the middle part of the window is greater than the width of the upper part. Only a roller 31 can be provided at one end of the curtain support rod 22 to drive the curtain support rod 22 to move between the two layers of glass 1. Then the width of the middle blackout curtain 21 is also greater than the width of the upper blackout curtain 21. Therefore, curtain support ribs 23 are provided at the folding crease to provide certain support to the middle part of the blackout curtain 21 to maintain a flat shape. In addition, the blackout curtain 21 is also made of a material with a certain hardness.

[0103] When unrolled, the reel 31 is rod-shaped, with one end connected to the curtain support rod 22 and the other end engaging the motor drive shaft that passes through the two layers of glass 1. The motor drives the motor drive shaft to rotate, thereby driving the reel 31 to reel in or out. Furthermore, a motor mounting bolt 35 is provided at one end of the drive shaft that passes through the two layers of glass 1. The motor drive shaft and the motor mounting bolt 35 engage and rotate relative to each other, preventing the motor from falling off.

[0104] A sealing layer 13 is provided at the edge between the two glass layers 1, sealing the space between the two glass layers 1 as a whole, ensuring the dryness of the interior of the double-glazed glass and preventing fogging. Sealing gaskets 34 are provided between the motor and the glass layer 1, and between the glass layer 1 and the motor mounting bolts 35, ensuring the tightness of the double-glazed glass and preventing the ingress of external air.

[0105] This solution also uses blackout curtains 21 to provide shading. Different shade properties can be achieved by selecting different shade curtains 21, providing flexibility and facilitating future expansion while also providing complete shading and privacy. Blackout curtains 21 can be completely opaque, or electronically controlled photochromic glass film can be used, with the addition of an electronic input unit to achieve different sunshade and privacy functions. The motor is activated by a switch on the door guard or through a smart device such as a gesture.
