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

[0056] According to the projection screen 40 of the first aspect of the embodiment 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 via 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, when the driving mechanism 60 drives the screen 50, the screen 50 can be rotated relative to the top frame 10 via the rotating shaft 51 to unfold or store the screen 50.

[0057] The driving mechanism 60 includes a first driving motor 6, a driving slider 7 and a driving rod 82. The first driving motor 6 is connected to the driving slider 7 in a transmission manner. The driving rod 82 is hingedly connected between the screen 50 and the driving slider 7. The first driving motor 6 drives the screen 50 to rotate around the rotating shaft 51 through the driving slider 7 and the driving rod 82. When the screen 50 rotates around the rotating shaft 51, the screen 50 can move between the storage position and the unfolding position. When the screen 50 is in the storage position, the screen 50 is located on the top of the vehicle, and the screen 50 does not occupy the space in the vehicle. When the passengers in the vehicle need to use the projection screen 40, the screen 50 can be driven to unfold by the first driving motor 6, and the projector 90 located on one side of the vehicle can be opened to project the picture onto the screen 50, which is convenient for the passengers in the vehicle to use. When the passengers in the vehicle do not need to use the projection screen 40, the first driving motor 6 can drive the projection screen 40 to be stored, so as to fix the screen 50 to the top of the vehicle. The first driving motor 6 drives the projection screen 40 to unfold or fold, which can provide convenience for the passengers in the vehicle to fold or unfold the screen 50. For example, the first drive motor 6 is a rotor motor.

[0058] When the screen 50 moves from the storage position to the deployment position, the screen 50 can stop at any position, that is, at the deployment position. The screen 50 at the storage position is located at the top of the vehicle, and the screen 50 at the deployment position can be perpendicular to the screen 50 at the storage position, or the angle between the screen 50 at the deployment position and the screen 50 at the storage position can be an acute angle. The deployment position of the screen 50 can be determined according to the needs of the passengers in the vehicle.

[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, and 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, and 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 pasted on 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 via the rotating shaft 51. The first driving motor 6 drives the screen 50 to rotate around the rotating shaft 51 via 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 space in the vehicle. When the screen 50 is in the deployed position, it can be used by the passengers in the vehicle. By driving the screen 50 to rotate by the first driving 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, and 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 needs to be used, the first driving motor 6 drives the driving shaft 81 to move, and when the driving shaft 81 moves, it can drive the driving slider 7 to slide in the slide groove 1, and when the driving slider 7 slides, it can drive the driving rod 82 to move, and when the driving rod 82 moves, it can drive the screen 50 to rotate, so that the screen 50 is located in the unfolded position; when the screen 50 is not needed, the first driving motor 6 drives the driving shaft 81 to move, and when the driving shaft 81 moves, it can drive the driving slider 7 to slide in the slide groove 1, and when the driving slider 7 slides, it can drive the driving rod 82 to move, and when the driving rod 82 moves, it can drive the screen 50 to rotate, so that the screen 50 is located in the storage 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 direction 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 with 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 force on both sides of the Y direction of the screen 50 is 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, and the first top rod and the second top rod are both provided with a slide groove 1 .

[0066] According to some embodiments of the first aspect of the present invention, referring to Figure 1-Figure 5 The driving rod 82 is located on the back side of the screen 50, and the back side of the screen 50 is the side of the display screen away from the screen 50. When the user uses the screen 50 to watch an image, the driving rod 82 is located on the back side of the screen 50, and the user is not easy to observe the driving rod 82, which improves the aesthetics.

[0067] According to some embodiments of the second aspect of the present invention, Figure 8-Figure 11 The driving rod 82 is located at 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, Figure 8-Figure 11 The driving slider 7 has a support rod 73, and the support rod 73 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 play a certain supporting role on the screen 50, thereby preventing the screen 50 from shaking when the vehicle is running.

[0069] For example, two driving sliders 7 are provided, and correspondingly, two supporting rods 73 are provided, and the two supporting rods 73 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 Figure 8-Figure 13 The driving slider 7 includes an active slider 71 and a driven slider 72. The first driving motor 6 is used to drive the active slider 71 to slide. The driven slider 72 is hinged to the driving rod 82. Both the active slider 71 and the driven slider 72 can be movably matched with the slide slot 1. The first driving motor 6 is used to drive the active slider 71 to slide in the slide slot 1. When the active slider 71 slides, it drives the driven slider 72 to slide in the slide slot 1. When the driven slider 72 moves, the driven slider 72 drives the driving rod 82 to move. When the driving rod 82 moves, it drives the screen to rotate, so that the screen can move between the storage state and the unfolded state. The support rod 73 is located on the active slider 71. The active slider 71 and the driven slider 72 have a mutually locked locked state and a mutually separated unlocked state.

[0070] 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 is separated from the driven slider 72, 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 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 spaced apart 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 rotating shaft 51 .

[0073] According to some embodiments of the second aspect of the present invention, Figure 8-Figure 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. The connecting rod 722 extends toward the active slider 71. The active slider 71 has a locking groove 711 arranged toward the connecting rod 722. The connecting rod 722 has a locking block 723. The locking block 723 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 arranged on the active slider 71, and the locking block 723 is arranged 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, so that the active slider 71 and the driven slider 72 are locked 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 located at 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 Fig.15 , Fig.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 cooperation 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, Figure 13-Figure 14 , Fig.16 The driven slider 72 has a locking protrusion 724 on the side facing the slide 1, and the slide 1 has a locking slot 11. The locking slot 11 cooperates with the locking protrusion 724. The locking slot 11 is located on the bottom wall of the slide 1, and the locking protrusion 724 is located above the bottom wall of the slide 1. When the locking protrusion 724 moves to the top of the locking slot 11, due to the gravity of the driven slider 72, the locking protrusion 724 falls into the locking slot 11, and the driven slider 72 is locked with the slide 1. When the screen 50 is in the storage position, the driven slider 72 has a locking position locked on the slide 1 corresponding to the length direction of the slide 1. When the driven slider 72 is in the locking position, the locking protrusion 724 and the locking slot 11 are locked with each other, so that the locking slot 711 and the locking block 723 are separated.

[0078] When the first drive motor 6 drives the screen 50 to move from the storage position toward the unfolded position, the first drive motor 6 drives the active slider 71 to move toward the direction of 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 unfolded position.

[0079] When the first drive motor 6 drives the screen 50 to move from the unfolded position toward the stowed position, the first drive motor 6 drives the active slider 71 to move in a direction away from the driven slider 72, and the active slider 71 drives the driven slider 72 to move to the locked position, and 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 stowed position.
