A projector 104 is arranged on the inner side of the roof and can project video information onto a projection screen 40. Typically, the vehicle 100 can be a passenger car with two front doors 101 and two rear doors 102.

[0065] exist Figure 1 In the embodiment, the projection curtain 40 is in a first front position in the interior of the vehicle 100 in the unfolded state, the second rod assembly 20 is in a free state, and the two extension rods 21a (see Figure 2 ) has not yet extended from the rod body 21.

[0066] exist Figure 2 In the figure, the projection screen 40 is in a rear second position in the interior of the vehicle 100, and the second rod assembly 20 is held on the two rear doors 102 by a guide rail system 30 on each of the two rear doors 102, so that the projection screen 40 can be in a predetermined usage state, and the occupants 106 sitting in the rear seats of the vehicle can watch videos, such as movies, TV series, video games, etc. in the interior of the vehicle with the help of the projector 104 and the projection screen system 105.

[0067] The first rod assembly 10 is configured to extend in the transverse direction of the vehicle on the inner side of the roof of the vehicle 100 and to be movably arranged in the longitudinal direction of the vehicle. The projection curtain 40 can be stored in the first rod assembly 10 and can be deployed from the first rod assembly 10 to a predetermined use state, in which the projection curtain 40 can provide a projection surface. Figure 8 is a schematic diagram of the projection curtain 40 in an unfolded state, and Fig. 9 is a cross-sectional view of the first rod assembly 10. The first rod assembly 10 includes a housing 41 in which a reel for the projection screen 40 and a motor 42 for driving the reel are mounted.

[0068] The second rod assembly 20 is disposed on the end of the projection screen 40 opposite to the first rod assembly 10, and is configured to be held on a vehicle component of the vehicle 100 in the passenger compartment of the vehicle when the projection screen 40 is in use. Figure 1 and Figure 2In the illustrated embodiment, in the use state of the projection curtain 40, the second rod assembly 20 can be held on the two rear doors 102 of the vehicle 100. To this end, the second rod assembly 20 can have an adjustable length, wherein the second rod assembly 20 includes a rod body 21 and an extension rod 21a on both sides of the rod body 21 that can be extended and retracted relative to the rod body 21. Each extension rod 21a can be equipped with a drive, especially a motor. Alternatively, the two extension rods 21a can be equipped with a common drive, especially a motor. This can achieve automatic extension and retraction of the two extension rods. Advantageously, the two extension rods can be held on the body component with their free ends by magnetic attraction.

[0069] For each end of the second rod assembly 20, or for the free end of each extension rod 21a, the projection curtain system 105 includes a corresponding rail system 30, which has a receiving portion 18. For aesthetic and safety reasons, the rail system 30 can be hidden in the corresponding vehicle door 102 and can be pushed out of the corresponding vehicle door 102. For this purpose, the vehicle door 102 can have a receiving chamber for the rail system 30, which has an opening, which can be closed by a cover plate, and the cover plate can be opened so that the rail system 30 can be pushed out of the receiving chamber through the opening and can be pushed into the receiving chamber from outside the receiving chamber through the opening. In order to minimize the opening, the opening can have approximately the same contour and size as the first rail 1 of the rail system 30, which will be described in more detail.

[0070] Figure 3 and Figure 4 3 are a top view and a front view of the guide rail system 30 . Figure 5A and 5B is a partial cross-sectional view of the guide rail system 30 in different states. Figure 3 and Figure 4 as well as Figure 5A In the embodiment, the two guide rails 1, 2 of the guide rail system 30 at least substantially overlap. Figure 5B In the embodiment, the two guide rails 1, 2 of the guide rail system 30 are perpendicular to each other.

[0071] The first guide rail 1 has a first side facing away from the second guide rail 2 and a second side facing the second guide rail 2. The first guide rail 1 has an elongated slit 16 (see Fig. 6A ), and having a guide groove on the second side.

[0072] The first slider 3 can move along the first guide rail 1. The first slider 3 includes a first component 3a and a second component 3b. The first component 3a is arranged on the first side of the first guide rail 1. The first component 3a can be driven by a second motor 12 and an associated screw 14 arranged on the first side of the first guide rail 1. The second component 3b is arranged in a guide groove on the second side of the first guide rail 1, and is thus movably guided along the first guide rail 1. The first component 3a has a first shaft hole 17a, and the second component 3b has a second shaft hole 17b. The rotating shaft 5 passes through the first shaft hole 17a, the gap 16 and the second shaft hole 17b. The rotating shaft 5 is rotatably supported in the first shaft hole 17a by a first bearing 6a, and is rotatably supported in the second shaft hole 17b by a second bearing 6b. When the first component 3a is driven by the second motor 12 via the associated screw 14 , the second component 3b coupled to the first component 3a via the rotating shaft 5 and the bearings 6a , 6b moves along the first guide rail 1 together with the first component 3a under the guidance of the guide groove of the first guide rail 1 .

[0073] The rotating shaft 5 is connected to the second guide rail 2 in a rotationally fixed manner, in other words, the rotating shaft 5 and the second guide rail 2 can rotate together. The rotating shaft 5 can be rotated by a first motor 11 arranged on a first side of the first guide rail 1, so as to place the two guide rails 1, 2 in a predetermined angular position relative to each other. Typically, the rotationally fixed connection can be achieved by a non-circular shaft segment and a non-circular hole.

[0074] The second guide rail 2 may have a recess 9 on its first side facing the first guide rail 1. Figure 5A The first angular position of 0° relative to the first guide rail 1 is rotated to a position as shown by means of the first motor 11 and the rotating shaft 5. Figure 5B In the second angular position of 90° relative to the first guide rail 1 shown, the first guide rail 1 and the second guide rail 2 can move toward each other by means of an external force, such as a magnetic attraction force or a spring preload, so that the second component 3b coupled to the first guide rail 1 in a rotationally fixed manner can sink into the recess 9 of the second guide rail 2, wherein the second component 3b protrudes from the first guide rail 1. Advantageously, the guide rail system 30 can have an electromagnet arrangement structure, which includes an electromagnetic coil 7 mounted on the rotating shaft 5 in the second shaft hole 17b and a magnet 8 arranged in the second guide rail 2.

The magnet 8 can be fixed in the mounting hole 22 and has a non-circular hole, not shown, which receives the non-circular end of the rotating shaft 5. In the second angular position, when the electromagnetic coil 7 is energized to generate a magnetic attraction force between the electromagnetic coil 7 and the magnet 8, the second guide rail 2 can be axially moved toward the first guide rail 1 on the rotating shaft 5 in a torsionally fixed connection, so that the second component 3b sinks into and is retained in the recess 9 of the second guide rail 2. At this time, when the electromagnetic coil 7 is reversely energized to generate a magnetic repulsion force between the electromagnetic coil 7 and the magnet 8, the second guide rail 2 can be axially moved away from the first guide rail 1 on the rotating shaft 5 in a torsionally fixed connection, so that the first guide rail 1 or the second component 3b is separated from the recess 9 of the second guide rail 2. Advantageously, the recess 9 can be configured as a rectangular recess.

[0075] The second guide rail 2 has a guide groove on its second side facing away from the first guide rail 1, in which the second slide 4 is movably received and can be driven by the third motor 13 and the associated screw 15. The second slide 4 provides a receiving portion 18 for the corresponding end of the second rod assembly 20 (or the free end of the extension rod 21b). Advantageously, if Figure 7C As shown, the second slide 4 may have a central recess as the receiving portion 18 , in which a magnet 19 is arranged, and the magnet 19 can apply a magnetic attraction force to the corresponding end of the second rod assembly 20 .

[0076] In such Figure 1 and 2 In the illustrated embodiment, the projection screen 40 can be housed in the first rod assembly 10. In an alternative embodiment, not shown, the projection screen 40 can be housed in the second rod assembly 20. In another alternative embodiment, not shown, the projection screen 40 can be housed partially in the first rod assembly and partially in the second rod assembly 20.

[0077] In the first embodiment, the projection area of ​​the projection screen 40 as well as the position and orientation of the projection screen 40 can be flexibly adjusted through the adjustability of the two sliders 3 and 4 of the guide rail system combined with the adjustability of the first rod assembly 10 in the longitudinal direction.

[0078] Next, a projection curtain system 105 according to an exemplary second embodiment of the present invention is described. Here, the differences between the second embodiment and the first embodiment are mainly described. For other aspects of the second embodiment that are not described in detail, reference can be made to the description of the first embodiment.

[0079] Fig.10 and Fig.11 Each of the figures is a perspective view of a section of a vehicle 100 having a projection screen system 105 according to a second specific embodiment of the present invention. Fig.10 In FIG. 1 , the projection screen 40 is in a first front position in the interior of the vehicle 100 and is stored in the first rod assembly 10 . Fig.11 In the embodiment, the projection screen 40 is in a rear second position in the interior of the vehicle 100, and the second rod assembly 20 is held on the seat backs of the two seats 31, 32 of the front seat row, so that the projection screen 40 can be in a predetermined use state.

[0080] like Figures 12A to 12C As shown, the second rod assembly 20 includes a rod body 21 and two connecting rods 21b on both sides of the rod body 21 that are foldable relative to the rod body 21.
