[0055] Reference below Figures 1-18 A projection screen 40 according to an embodiment of the present invention is described.

[0056] According to the projection screen 40 of the embodiment of the first aspect of the present invention, the projection screen 40 is used for a vehicle, the vehicle includes a top frame 10, the projection screen 40 includes a screen 50 and a driving mechanism 60, the screen 50 is rotatably connected to the top frame 10 through a rotating shaft 51, the rotating shaft 51 passes through the screen 50 and is fixedly connected to the screen 50, the rotating shaft 51 is rotatably connected to the top frame 10, and when the driving mechanism 60 drives the screen 50, the screen 50 can be rotated relative to the top frame 10 through the rotating shaft 51 to unfold or store the screen 50.

[0057] The drive mechanism 60 includes a first drive motor 6, a drive slider 7, and a drive rod 82. The first drive motor 6 is in transmission connection with the drive slider 7, and the drive rod 82 is hingedly connected between the screen 50 and the drive slider 7. The first drive motor 6 drives the screen 50 to rotate about the rotation axis 51 via the drive slider 7 and the drive rod 82. As the screen 50 rotates about the rotation axis 51, it can move between a stowed position and an extended position. In the stowed position, the screen 50 is located on the roof of the vehicle, eliminating space inside the vehicle. When a passenger in the vehicle needs to use the projection screen 40, the first drive motor 6 can drive the screen 50 to unfold, and a projector 90 located on one side of the vehicle can be turned on to project images onto the screen 50, making it easier for the passenger to use the projection screen 40. When the passenger in the vehicle no longer needs to use the projection screen 40, the first drive motor 6 can drive the projection screen 40 to be retracted, thereby securing the screen 50 to the roof of the vehicle. The first drive motor 6 drives the projection screen 40 to unfold or retract, providing convenience for the passenger in the vehicle. For example, the first driving motor 6 is a rotor motor.

[0058] When the screen 50 moves from the stowed position to the deployed position, it can stop at any position, i.e., be in the deployed position. The screen 50 in the stowed position is located at the top of the vehicle, and the screen 50 in the deployed position can be perpendicular to the screen 50 in the stowed position, or the angle between the screen 50 in the deployed position and the screen 50 in the stowed position can be acute. The deployed position of the screen 50 can be determined based on the needs of the vehicle occupants.

[0059] When the screen 50 is in the storage position, the first drive motor 6 drives the drive slider 7 to move. When the drive slider 7 moves, it drives the drive rod 82 to move. When the drive rod 82 moves, it drives the screen 50 to rotate so that the screen 50 can be unfolded. The first drive motor 6 stops running, so that the screen 50 remains in the unfolded position; when the screen 50 is not needed, the first drive motor 6 drives the drive slider 7 to move. When the drive slider 7 moves, it drives the drive rod 82 to move. When the drive rod 82 moves, it drives the screen 50 to rotate so that the screen 50 can be closed. The first drive motor 6 stops running, so that the screen 50 remains in the storage position.

[0060] For example, the screen 50 is made of a PC panel or glass, and a projection material is coated on the surface of the panel material or a projection substrate is attached to the surface.

[0061] According to the projection screen 40 of the embodiment of the present invention, the screen 50 is rotatably connected to the top frame 10 through the rotating shaft 51, and the first drive motor 6 drives the screen 50 to rotate around the rotating shaft 51 through the driving slider 7 and the driving rod 82, so that the screen 50 can move between the storage position and the deployed position. When the screen 50 is in the storage position, it does not occupy the space in the car. When the screen 50 is in the deployed position, it can be used by the passengers in the car. By driving the screen 50 to rotate by the first drive motor 6, the practicality and convenience of storing and deploying the screen 50 can be improved.

[0062] According to some embodiments of the present invention, referring to Figure 1-Figure 5 、 Figure 7 The top frame 10 has a slide groove 1 extending along the length direction of the top frame 10, the driving slider 7 cooperates with the slide groove 1, the first driving motor 6 includes a driving shaft 81, and the driving slider 7 is connected to the driving shaft 81 in a transmission manner. When the screen 50 is needed, the first driving motor 6 drives the driving shaft 81 to move. When the driving shaft 81 moves, it can drive the driving slider 7 to slide in the slide groove 1. When the driving slider 7 slides, it can drive the driving rod 82 to move. When the driving rod 82 moves, it can drive the screen 50 to rotate, so that the screen 50 is in the deployed position; when the screen 50 is not needed, the first driving motor 6 drives the driving shaft 81 to move. When the driving shaft 81 moves, it can drive the driving slider 7 to slide in the slide groove 1. When the driving slider 7 slides, it can drive the driving rod 82 to move. When the driving rod 82 moves, it can drive the screen 50 to rotate, so that the screen 50 is in the stored position.

[0063] For example, the drive shaft 81 may be a flexible shaft, and the first drive motor 6 may be disposed on one side of the top frame 10 in the X direction (the front-rear direction of the vehicle), which may facilitate the arrangement of the first drive motor 6 .

[0064] According to some embodiments of the present invention, referring to Figure 1-Figure 5 There are two driving rods 82, which are respectively located on both sides of the Y direction of the screen 50 (the left and right directions of the vehicle). The end of each driving rod 82 is hinged with a driving slider 7. Two slide grooves 1 are provided on the top frame 10. The two slide grooves 1 correspond one-to-one to the two driving sliders 7. Driving rods 82 are provided on both sides of the Y direction of the screen 50. When the first driving motor 6 drives the driving rod 82 to move, the driving rod 82 can simultaneously pull the two sides of the Y direction of the screen 50 to move, so that the forces on both sides of the Y direction of the screen 50 are balanced, and the screen 50 can be rotated more smoothly.

[0065] For example, the top frame 10 includes a first top rod and a second top rod extending along the X direction of the vehicle. The first top rod and the second top rod are spaced apart along the Y direction of the vehicle. The first top rod and the second top rod are both provided with a sliding groove 1 .

[0066] According to some embodiments of this aspect, referring to Figure 1-Figure 5 The driving rod 82 is located on the back side of the screen 50, which is the side of the display screen facing away from the screen 50. When the user uses the screen 50 to view images, the driving rod 82 is located on the back side of the screen 50, which is difficult for the user to see, thereby improving the aesthetics.

[0067] According to some embodiments of this second aspect, referring to Figures 8-11 The driving rod 82 is located on the front side of the screen 50 , and the front side of the screen 50 is the side close to the display screen of the screen 50 .

[0068] According to some embodiments of the second aspect of the present invention, referring to Figures 8-11 The driving slider 7 has a support rod 73, which extends toward the side wall of the screen 50, that is, the support rod 73 extends along the Y direction of the vehicle. The side wall of the screen 50 has a support groove 52. In the storage position, the support rod 73 is located in the support groove 52. By locating the support rod 73 in the support groove 52, the support rod 73 can provide a certain support for the screen 50, thereby preventing the screen 50 from shaking when the vehicle is running.

[0069] For example, there are two driving sliders 7, and correspondingly, there are two support rods 73, which are respectively supported on both sides of the Y direction of the screen 50. According to some embodiments of the second aspect of the present invention, referring to Figures 8-13 The drive slider 7 includes an active slider 71 and a passive slider 72. The first drive motor 6 is used to drive the active slider 71 to slide. The passive slider 72 is hinged to the drive rod 82. Both the active slider 71 and the passive slider 72 can flexibly cooperate with the chute 1. The first drive motor 6 is used to drive the active slider 71 to slide within the chute 1. When the active slider 71 slides, it drives the passive slider 72 to slide within the chute 1. When the passive slider 72 is engaged, the passive slider 72 drives the drive rod 82 to move. When the drive rod 82 moves, it drives the screen to rotate, so that the screen can move between the stowed state and the unfolded state. The support rod 73 is located on the active slider 71. The active slider 71 and the passive slider 72 have a locked state in which they are locked to each other and an unlocked state in which they are separated from each other.

[0070] When the screen 50 is in the storage position, the active slider 71 and the driven slider 72 are in the unlocked state, the active slider 71 and the driven slider 72 are separated, and the support rod 73 is located in the support groove 52; at this time, the first drive motor 6 drives the active slider 71 to slide, and the first drive motor 6 can only drive the active slider 71 to slide. When the active slider 71 approaches the direction of the driven slider 72, the active slider 71 and the driven slider 72 are locked, and the active slider 71 can drive the driven slider 72 to slide synchronously, so that the screen reaches the unfolded position.

[0071] When the screen 50 is in the expanded position, the active slider 71 and the driven slider 72 are locked with each other, and the first drive motor 6 is used to drive the active slider 71 and the driven slider 72 to slide synchronously. When the screen 50 is in the stored position, the drive rod 82 moves to the extreme position, and the first drive motor 6 continues to drive the active slider 71 to move. Under the external force of the first drive motor 6, the active slider 71 and the driven slider 72 are separated from each other. The first drive motor 6 can only drive the active slider 71 to slide, so that the support rod 73 is located in the support groove 52, so that the support position of the support rod 73 is separated from the support position of the driven slider 72 supporting the screen 50, and can be supported at multiple positions of the screen 50, so that the screen 50 is more stable when in the stored position.

[0072] For example, the supporting groove 52 is located at an edge of the screen 50 away from the rotation shaft 51 .

[0073] According to some embodiments of the second aspect of the present invention, referring to Figures 8-13 The driven slider 72 includes a slider body 721 and a connecting rod 722. The connecting rod 722 is connected to one end of the slider body 721 and extends toward the active slider 71. The active slider 71 has a locking groove 711 disposed toward the connecting rod 722. The connecting rod 722 has a locking block 723 that cooperates with the locking groove 711. The connecting rod 722 can be located at the bottom of the active slider 71 to facilitate the cooperation between the locking groove 711 and the locking block 723. The locking groove 711 is provided on the active slider 71, and the locking block 723 is provided on the driven slider 72 to facilitate the locking of the active slider 71 and the driven slider 72.

[0074] When the screen 50 moves from the storage position to the deployment position, the first drive motor 6 is used to drive the active slider 71 to slide toward the driven slider 72. When the active slider 71 moves to above the connecting rod 722 of the driven slider 72, the locking groove 711 and the locking block 723 are locked, thereby locking the active slider 71 and the driven slider 72 with each other. The first drive motor 6 continues to drive the active slider 71 to slide. When the active slider 71 slides, it drives the driven slider 72 to slide. When the driven slider 72 slides, it drives the driving rod 82 to slide. When the driving rod 82 slides, it drives the screen 50 to rotate, so as to deploy the screen 50.

[0075] When the screen 50 moves from the deployed position toward the stored position, the locking groove 711 and the locking block 723 are locked, and the first drive motor 6 is used to drive the active slider 71 and the driven slider 72 to slide synchronously. When the screen 50 is in the stored position, the drive rod 82 moves to the extreme position, and the first drive motor 6 continues to drive the active slider 71 to move. Under the external force of the first drive motor 6, the locking groove 711 and the locking block 723 are separated, thereby separating the active slider 71 and the driven slider 72 from each other. The first drive motor 6 can only drive the active slider 71 to slide so that the support rod 73 is located in the support groove 52.

[0076] According to the second embodiment of the present invention, referring to Figure 15 、 Figure 18 The locking groove 713 has a first guide surface 712 on the groove wall close to the driven slider 72, and the first guide surface 712 is inclined toward the direction of the driven slider 72. The locking block 723 has a second guide surface 7232, and the second guide surface 7232 cooperates with the first guide surface 712. When the active slider 71 and the driven slider 72 are unlocked, under the action of the first guide surface 712 and the second guide surface guiding 7231, the first guide surface 712 can guide the second guide surface 7232 to move, so that the locking block 723 can fall off from the locking groove 711.

[0077] According to some embodiments of the second aspect of the present invention, referring to Figure 13-14 、 Figure 16 The driven slider 72 has a latching protrusion 724 on the side facing the chute 1. The chute 1 has a latching slot 11, which engages with the latching protrusion 724. The latching slot 11 is located on the bottom wall of the chute 1, and the latching protrusion 724 is located above the bottom wall of the chute 1. When the latching protrusion 724 moves above the latching slot 11, the latching protrusion 724 falls into the latching slot 11 due to the gravity of the driven slider 72, and the driven slider 72 is locked with the chute 1. When the screen 50 is in the storage position, the driven slider 72 has a locked position corresponding to the length direction of the chute 1. When the driven slider 72 is in the locked position, the latching protrusion 724 and the latching slot 11 are locked with each other, causing the locking groove 711 and the locking block 723 to separate.

[0078] When the first drive motor 6 drives the screen 50 to move from the storage position toward the deployed position, the first drive motor 6 drives the active slider 71 to move toward the driven slider 72, and the locking block 723 is located in the locking groove 711, so that when the active slider 71 and the driven slider 72 are locked with each other, the latching protrusion 724 disengages from the latching groove 11, so that the driven slider 72 and the slide groove 1 are unlocked from each other. Under the continued drive of the first drive motor 6, the active slider 71 drives the driven slider 72 to slide synchronously to drive the screen 50 to reach the deployed position.

[0079] When the first drive motor 6 drives the screen 50 to move from the unfolded position toward the stored position, the first drive motor 6 drives the active slider 71 to move in the direction away from the driven slider 72, and the active slider 71 drives the driven slider 72 to move to the locked position. The latch 724 is located in the latch groove 11, so that the driven slider 72 is fixed on the slide groove 1, and the screen 50 reaches the stored position. At this time, the first drive motor 6 continues to drive the active slider 71 to move, and the locking block 723 disengages from the locking groove 711, so that the active slider 71 is separated and unlocked from the driven slider 72. Figure 14 、 Figure 16 The slot 11 has a third guide surface 111 on its wall near the driven slider 72, which is tilted toward the driven slider 72. The latching protrusion 724 has a fourth guide surface 725 that cooperates with the third guide surface 111.
