[0030] In the prior art, the way to increase the display scenes is to add projectors to realize more projection scenes. However, the structure of installing multiple projectors is complicated and requires a large space, while there is not enough space in the car to install multiple projectors, which cannot meet the needs of multiple projection stations; and as the number of projectors increases, the preparation cost will also double.
[0031] Based on the above situation, the present application provides an adjustment device and a projection system, which can solve the problem that the prior art cannot meet the needs of multiple projection stations in a smaller space.
[0032] The optical adjustment assembly provided by the present application includes: a first rotating assembly and a first connecting assembly connected to each other, and a second rotating assembly and a second connecting assembly connected to each other; one end of the first connecting assembly away from the first rotating assembly is connected to the second rotating assembly, and one end of the second connecting assembly away from the second rotating assembly is used to be fixedly connected to the projector; wherein, when the first rotating assembly is excited, the first connecting assembly is driven to rotate around the first axis in the first plane, and when the first connecting assembly rotates, the second rotating assembly and the second connecting assembly are driven to rotate around the first axis, so that the second connecting assembly drives the projector to rotate around the first axis; when the second rotating assembly is excited, the second connecting assembly is driven to rotate around the second axis in the second plane, so that the second connecting assembly drives the projector to rotate around the second axis; wherein, the first plane is perpendicular to the second plane, the first axis is perpendicular to the first plane, and the second axis is perpendicular to the second plane. By adjusting the projection position of the projector in the first plane through the first rotating assembly, the first connecting assembly, the second rotating assembly and the second connecting assembly, and adjusting the projection position of the projector in the second plane through the second rotating assembly and the second connecting assembly, multiple projection positions can be realized through one projector, thereby meeting the needs of multiple projection positions in a smaller space.
[0033] To illustrate the specific structure of the regulating device of this application, please refer to Figure 1 , Figure 1 It is a schematic diagram of the assembly structure of the regulating device of the present application.
[0034] In this embodiment, the adjustment device 100 includes a first rotating component 10 and a first connecting component 20 connected to each other, and a second rotating component 30 and a second connecting component 40 connected to each other. One end of the first connecting component 20 away from the first rotating component 10 is connected to the second rotating component 30, and one end of the second connecting component 40 away from the second rotating component 30 is used to be fixedly connected to the projector 50. When the first rotating component 10 is excited, it drives the first connecting component 20 to rotate around the first axis y in the first plane, and when the first connecting component 20 rotates, it drives the second rotating component 30 and the second connecting component 40 to rotate around the first axis, so that the second connecting component 40 drives the projector 50 to rotate around the first axis. When the second rotating component 30 is excited, it drives the second connecting component 40 to rotate around the second axis in the second plane, so that the second connecting component 40 drives the projector 50 to rotate around the second axis. The first plane is perpendicular to the second plane, the first axis is perpendicular to the first plane, and the second axis is perpendicular to the second plane.
[0035] In this embodiment, the first axis is defined as the y-axis, the second axis is defined as the z-axis, the first plane is defined as the plane formed by the z-axis and the x-axis, and the second plane is defined as the plane formed by the y-axis and the x-axis, wherein the y-axis is perpendicular to the z-axis, and the x-axis is perpendicular to the y-axis and the z-axis respectively.
[0036] In some embodiments, the arrangement direction of the first rotating assembly 10 and the first connecting assembly 20 is parallel to the first axis, and the arrangement direction of the second rotating assembly 30 and the second connecting assembly 40 is parallel to the second axis.
[0037] In some implementations, the projector 50 is an ultra short throw projector.
[0038] In some implementations, when the projector 50 is mounted on the second connecting assembly 40 , keystone correction has been completed in advance at each projection station and stored in the control device.
[0039] In this embodiment, the projector 50 is directly connected to the second connecting component 40 , but has no direct connection relationship with the first rotating component 10 and the first connecting component 20 .
[0040] In the present embodiment, when the first rotating component 10 drives the first connecting component 20 to rotate around the y-axis on the first plane, the second rotating component 30 connected thereto can be driven to rotate synchronously through the first connecting component 20, and the second connecting component 40 can be driven to rotate through the second rotating component 30, and then the projector 50 can be driven to rotate synchronously around the y-axis on the first plane through the second connecting component 40, so as to adjust the projector 50 to the preset position of the required projection station in the first plane, so that the projector 50 can be projected at different projection stations in the first plane, thereby realizing the projection position of the projector 50 in the first plane.
[0041] When the first rotating component 10 is excited, the second connecting component 40 rotates synchronously with the first connecting component 20, the first connecting component 20 and the second connecting component 40 remain relatively stationary, and the orthographic projection of the first connecting component 20 on the first plane has an overlapping area with the orthographic projection of the second connecting component 40 on the first plane.
[0042] In the present embodiment, when the second rotating component 30 drives the second connecting component 40 to rotate around the z-axis in the second plane, the second connecting component 40 can drive the projector 50 fixedly connected thereto to rotate synchronously around the z-axis, so as to adjust the projector 50 to a preset position of a desired projection station in the second plane, so that the projector 50 can project at the projection station in the second plane, thereby realizing the projection position of the projector 50 in the second plane.
[0043] When the second rotating component 30 is excited, only the second connecting component 40 starts to rotate, the first connecting component 20 remains stationary, and the angle between the second connecting component 40 and the first connecting component 20 starts to change.
[0044] It can be understood that by adjusting the projection position of the projector 50 in the first plane through the first rotating assembly 10, the first connecting assembly 20, the second rotating assembly 30 and the second connecting assembly 40, the adjustment function of the horizontal rotating platform can be realized through the first rotating assembly 10, the first connecting assembly 20, the second rotating assembly 30 and the second connecting assembly 40. By adjusting the projection position of the projector 50 in the second plane through the second rotating assembly 30 and the second connecting assembly 40, the adjustment function of the vertical rotating platform can be realized through the second rotating assembly 30 and the second connecting assembly 40, that is, the adjustment device 100 can perform multi-position projection based on the dual platform.
[0045] It can be understood that, since the adjustment device 100 can control one projector 50 for multi-station projection based on the dual pan-tilt platform, this embodiment can meet the needs of multiple projection stations in a smaller space. Furthermore, since this embodiment can realize multiple projection stations with only one projector 50, the preparation cost of realizing multiple projection stations can also be reduced.

[0050] In some implementations, the length of the first plate 21 on the x-axis is smaller than the length of the second plate 22 on the x-axis.
[0051] In this embodiment, when the first rotating member 12 is excited, it rotates around the first axis (y-axis), and drives the first plate 21 and the second plate 22 to rotate around the first axis. When the second plate 22 rotates, it drives the second rotating component 30 and the second connecting component 40 to rotate around the first axis, so that the second connecting component 40 drives the projector 50 to rotate around the first axis.

[0061] In some embodiments, the first rotating member 12 is a first circular turntable, and a first hollow area (not shown) is disposed in the middle of the first bottom surface 112 of the first fixing seat 11 .
[0062] In some embodiments, the first rotating assembly 10 includes a first driving assembly 13, and the first driving assembly 13 includes a first shell 131 and a first rotating shaft (not shown). The first shell 131 is fixedly connected to the first fixed seat 11 and is arranged on the first side 113 of the first fixed seat 11. The first rotating shaft extends from the first shell 131 and passes through the first hollow area of the first bottom surface 112 to be fixedly connected to the first circular rotating disk. The first circular rotating disk is circularly symmetrical with respect to the first rotating shaft.

The second rotating shaft extends from the second housing 331 and passes through the second hollow area of the second bottom surface 312 to be fixedly connected to the second circular rotating disk. The second circular rotating disk is circularly symmetrical with respect to the second rotating shaft. When the second driving assembly 33 is excited, it drives the second rotating shaft to rotate, so as to drive the second circular rotating disk to rotate around the second rotating shaft.

[0066] In some specific embodiments, an annular through hole is provided in the middle of the second rotating member 32, and the second rotating shaft passes through the annular through hole and is fixedly connected to the second rotating member 32. In other specific embodiments, the second rotating shaft is directly fixedly connected to the bottom of the second rotating member 32, which is not limited in the present application.
[0067] In some implementations, the adjustment device 100 includes a control device (not shown), which is communicatively connected with the first driving assembly 13 , the second driving assembly 33 , and the projector 50 .
[0068] In some specific implementations, the control device is a microcontroller unit (MCU).
[0069] In some specific embodiments, the first drive assembly 13 and the second drive assembly 33 are both motor assemblies, and the rotation speeds of the first drive assembly 13 and the second drive rotating member are controlled by a program burned into the control device. Among them, the first drive assembly 13 and the second drive assembly 33 are both integrated with a rotary encoder, which is used to calculate the number of rotations of the motor. When the number of rotations reaches a preset number of rotations, it indicates that the rotation is completed. The control device can also control the first drive assembly 13 or the second drive assembly 33 to reverse, so that the first rotating member 12 or the second rotating member 32 rotates to the initial position.
[0070] It can be understood that, through the cooperation of the control device, the first drive assembly 13 and the first rotating member 12, the projector 50 can be accurately controlled to rotate to a preset position in the first plane, thereby realizing the projection position of the projector 50 in the first plane. Through the cooperation of the control device, the second drive assembly 33 and the second rotating member 32, the projector 50 can be accurately controlled to rotate to a preset position in the second plane, thereby realizing the projection position of the projector 50 in the second plane.
[0071] Continue reading Figure 2In some embodiments, a first baffle 121 and a second baffle 122 are provided at the edge of the first rotating member 12. The angle of the minor arc between the first baffle 121 and the second baffle 122 is 90°. A first sensor 101 and a second sensor 102 are respectively provided at the middle of the adjacent two side edges of the first fixing seat 11. A first power supply interface a is provided on the first fixing seat 11 to supply power to the first sensor 101 and the second sensor 102 through the first power supply interface a.
[0072] The first sensor 101 and the second sensor 102 are connected to the control device for communication. In some specific implementations, the first sensor 101 and the second sensor 102 are both photoelectric switches. In some specific implementations, the first sensor 101 and the second sensor 102 are connected to the control device via a wire.
[0073] In this embodiment, when the first rotating member 12 rotates to the first position around the first rotating axis, the orthographic projection of the first baffle 121 on the first plane overlaps with the orthographic projection of the first sensor 101 on the first plane. When the first rotating member 12 rotates to the second position around the first rotating axis, the orthographic projection of the second baffle 122 on the first plane overlaps with the orthographic projection of the second sensor 102 on the first plane.
[0074] In a specific implementation scenario, such as Figure 2 As shown, the first rotating member 12 is located in the second position, and the orthographic projection of the second baffle 122 on the first plane has an overlapping area with the orthographic projection of the second sensor 102 on the first plane. At this time, the projector 50 is in the preset position corresponding to the first projection station. By projecting at the first projection station through the projector 50, the projection picture can be displayed on the first projection screen.
[0075] In another specific implementation scenario, the control device receives an external signal for controlling the rotation of the first drive assembly, and sends a control signal to the first drive assembly 13 to rotate the first drive assembly 13. At this time, if the first rotating member 12 is in the second position, the first rotating member 12 is driven by the first rotating shaft to rotate counterclockwise around the y-axis in the first plane. When the first rotating member 12 rotates to the first position (rotated 180° counterclockwise relative to the second position), the positive projection of the first baffle 121 on the first plane overlaps with the positive projection of the first sensor 101 on the first plane. After the first sensor 101 senses the first baffle 121, it transmits a signal to the control device so that the control device controls the first drive assembly 13 to stop rotating based on the signal transmitted by the first sensor 101. At this time, the projector 50 is synchronously driven by the first connecting assembly 20, the second rotating assembly 30 and the second connecting assembly 40, and rotates around the y-axis in the first plane to the preset position corresponding to the second projection station. In some specific implementations, the second projection station is an intermediate station, and the projection image is not displayed. In some other specific implementations, the projector 50 performs projection at the second projection station, and the projection picture can be displayed on the third projection screen, which is not limited in the present application.
[0076] In another specific implementation scenario, the control device receives an external signal and sends a control signal to the first drive assembly 13 to rotate the first drive assembly 13. At this time, if the first rotating member 12 is in the first position, the first rotating member 12 is driven by the first rotating shaft to rotate clockwise around the y-axis in the first plane. When the first rotating member 12 rotates to the second position (rotated 180° clockwise relative to the first position), the positive projection of the second baffle 122 on the first plane overlaps with the positive projection of the second sensor 102 on the first plane. After the second sensor 102 senses the second baffle 122, it transmits a signal to the control device so that the control device controls the first drive assembly 13 to stop rotating based on the signal transmitted by the second sensor 102. Under the synchronous drive of the first rotating member 12, the first connecting assembly 20, the second rotating assembly 30 and the second connecting assembly 40, the projector 50 rotates around the y-axis in the first plane to the preset position corresponding to the first projection station. The projector 50 projects at the first projection station, and the projection image can be displayed on the first projection screen.
[0077] In the above implementation scenario, when the first rotating member 12 is excited, the second connecting component 40 rotates synchronously with the first connecting component 20, the first plate 21 and the third plate 41 remain relatively still, and the angle formed between the first plate 21 and the third plate 41 is 0°.
[0078] It can be understood that the first baffle 121 and the second baffle 122 are sensed by the first sensor 101 and the second sensor 102, and a signal is transmitted to the control device after sensing the obstruction of the corresponding baffles, so that the control device controls the first drive component 13 to stop rotating, thereby ensuring that the rotation of the first rotating member 12 does not exceed the preset angle.
[0079] Continue reading Figure 4 In some embodiments, a third baffle 321 is disposed at the edge of the second rotating member 32, and a third sensor 301 is disposed at the middle of one side edge of the second fixing seat 31. A second power supply interface b is disposed on the second fixing seat 31 to supply power to the third sensor 301 through the second power supply interface b.
[0080] The third sensor 301 is connected to the control device for communication. In some specific implementations, the third sensor 301 is a photoelectric switch. In some specific implementations, the third sensor 301 is connected to the control device via a wire.
[0081] In this embodiment, when the second rotating member 32 rotates to the third position around the second rotating axis, the orthographic projection of the third blocking piece 321 on the second plane overlaps with the orthographic projection of the third sensor 301 on the second plane.
[0082] In a specific implementation scenario, when the first rotating member 12 is in the first position and the projector 50 is in the preset position corresponding to the second projection station in the first plane, after the control device receives the signal that the first driving assembly 13 stops rotating, if it receives an external signal to control the rotation of the second driving assembly 33, it sends a control signal to the second driving assembly 33 to rotate the second driving assembly 33, and drives the second rotating member 32 to rotate counterclockwise around the z-axis in the second plane through the second rotating shaft. When the second rotating member 32 rotates to the third position, the angle between the third plate body 41 and the first plate body 21 changes from 0° to 90°, and the orthographic projection of the third baffle 321 on the second plane overlaps with the orthographic projection of the third sensor 301 on the second plane. After the third sensor 301 senses the third baffle 321, it transmits a signal to the control device, so that the control device controls the second driving assembly 33 to stop rotating based on the signal transmitted by the third sensor 301. At this time, the projector 50 rotates around the z-axis in the second plane to a preset position corresponding to the third projection station under the synchronous drive of the second rotating member 32 and the second connecting assembly 40. The projector 50 projects at the third projection station, and the projection image can be displayed on the second projection screen.
[0083] It can be understood that the third baffle 321 is sensed by the third sensor 301, and a signal is transmitted to the control device after sensing the blocking of the third baffle 321, so that the control device controls the second drive assembly 33 to stop rotating, thereby ensuring that the rotation of the second rotating member 32 does not exceed the preset angle.
[0084] In another specific implementation scenario, when the second rotating member 32 is in the third position and the projector 50 is in the preset position corresponding to the third workstation in the second plane, if the control device receives an external signal for controlling the rotation of the second drive component 33, a control signal is sent to the second drive component 33 to rotate the second drive component 33, and the second rotating member 32 is driven to rotate clockwise around the z-axis in the second plane through the second shaft. When the angle between the third plate 41 and the first plate 21 changes from 90° to 0°, since there is an overlapping area between the orthographic projection of the first plate 21 on the first plane and the orthographic projection of the third plate 41 on the first plane, the third plate 41 is restricted from continuing to rotate clockwise around the z-axis, so that the projector 50 is in the preset position corresponding to the second projection workstation.
[0085] It can be understood that, since the clockwise rotation of the third plate body 41 can be limited by the first plate body 21 , only the third baffle 321 and the third sensor 301 are provided, and the control of the rotation angle can be achieved by a single baffle.
[0086] In the above-mentioned embodiment, the external signal received by the control device may be input through a remote control, an in-vehicle control button, visual gesture recognition, or other input methods, which is not limited in this application.
[0087] In some embodiments, a first angle sensor is disposed between the first rotating member 12 and the first fixed seat 11, a second angle sensor is disposed between the second rotating member 32 and the second fixed seat 31, and the control device is communicatively connected with the first angle sensor and the second angle sensor.
[0088] When the first angle sensor detects that the first rotating member 12 rotates 180° counterclockwise from the second position (rotates to the first position), the first angle sensor transmits a signal to the control device, so that the control device controls the first driving component 13 to stop rotating based on the signal transmitted by the first angle sensor. Alternatively, when the first rotating member 12 is detected to rotate 180° clockwise from the first position (rotates to the second position), the first angle sensor transmits a signal to the control device, so that the control device controls the second driving component 33 to stop rotating based on the signal transmitted by the second angle sensor.
[0089] It can be understood that the rotation angles of the first rotating member 12 and the second rotating member 32 are detected by the first angle sensor and the second angle sensor, and a signal is transmitted to the control device after the predetermined angle is detected, so that the control device controls the first drive component 13 or the second drive component 33 to stop rotating, thereby ensuring that the rotation of the first rotating member 12 and the second rotating member 32 does not exceed the preset angle.
[0090] It can be understood that by providing the first baffle 121, the second baffle 122, the first sensor 101, and the second sensor 102, when the first angle sensor is damaged, it can still be ensured that the rotation of the first rotating member 12 does not exceed the preset angle, thereby avoiding damage to the motor due to stalling. By providing the third baffle 321 and the third sensor 301, when the second angle sensor is damaged, it can still be ensured that the rotation of the second rotating member 32 does not exceed the preset angle, thereby avoiding damage to the motor due to stalling, thereby improving the adjustment accuracy, stability, and safety of the adjustment device 100.
[0091] Correspondingly, the present application provides a projection system.
[0092] For details, please refer to Figure 6 , Figure 7 and Figure 8 , Figure 6 is a schematic diagram of the projection system of the present application when realizing the first projection station, Figure 7 is a schematic diagram of the projection system of the present application when realizing the second projection station, Figure 8 It is a schematic diagram of the projection system of the present application when realizing the third projection station.
[0093] In this embodiment, the projection system 200 includes a first projection screen 51, a second projection screen 52, a projector, and the adjustment device 100 as described above. The first projection screen 51 and the second projection screen 52 are arranged vertically, and the adjustment device 100 is arranged between the first projection screen 51 and the second projection screen 52. The second connecting component of the adjusting device 100 is fixedly connected to the projector. Among them, when the first rotating component of the adjusting device 100 is excited, it drives the first connecting component to rotate around the first axis (y axis) in the first plane, and when the first connecting component rotates, it drives the second rotating component and the second connecting component to rotate around the first axis, so that the second connecting component drives the projector to rotate around the first axis, and then projects the projection light emitted by the projector onto the first projection screen 51. When the second rotating component is excited, it drives the second connecting component to rotate around the second axis (z axis) in the second plane, so that the second connecting component drives the projector to rotate around the second axis, and then projects the projection light emitted by the projector onto the second projection screen 52. The first plane is perpendicular to the plane where the first projection screen 51 is located, the second plane is perpendicular to the plane where the second projection screen 52 is located, the first axis is perpendicular to the first plane, and the second axis is perpendicular to the second plane.
[0094] In some implementations, the first projection screen 51 is an electric curtain.
[0095] In some implementations, the second projection screen 52 is a skylight. In some specific implementations, the skylight interlayer contains a dimming film that can adjust the light transmittance, so that the image can be projected without affecting the light transmission function of the skylight itself.
[0096] like Figure 6 As shown, when the first rotating member in the first rotating assembly of the adjusting device 100 is located in the second position, the projection system 200 is in an initial state. At this time, the projector 50 is in the first projection position. People in the vehicle can use but are not limited to remote controls, in-vehicle control buttons, visual gesture recognition, etc. to start the projection system 200. The control device in the adjusting device 100 controls the first projection screen 51 to electrically descend, the projector 50 turns on the light, and the projection picture is projected according to the picture ratio, color gamut, and light output brightness of the projection position corresponding to the first projection screen 51, so as to realize the projection scene of the first projection screen 51.
[0097] In this embodiment, when the control device receives an external signal to switch to the second projection station, the control device sends a light-off signal to the projector so that the projector turns off the light, and then sends a control signal to the first drive component in the first rotating component so that the first drive component rotates, and the first drive component drives the first rotating member to rotate counterclockwise around the y-axis in the first plane. When the first rotating member rotates to the first position (rotated 180° counterclockwise relative to the second position), the positive projection of the first baffle provided on the first rotating member on the first plane overlaps with the positive projection of the first sensor in the first fixed seat on the first plane. After the first sensor senses the first baffle, it transmits a signal to the control device so that the control device controls the first drive component to stop rotating based on the signal transmitted by the first sensor. At this time, the projector rotates around the y-axis in the first plane to a preset position corresponding to the second projection station under the synchronous drive of the first connecting component, the second rotating component and the second connecting component, such as Figure 7 shown.
[0098] Further, after receiving the signal that the first driving component stops rotating, the control device continues to receive the external signal for controlling the rotation of the second driving component in the second rotating component, and sends a control signal to the second driving component to rotate the second driving component, and drives the second rotating member to rotate counterclockwise around the z-axis in the second plane through the second rotating shaft. When the second rotating member rotates to the third position, the angle between the third plate in the second connecting component and the first plate in the first connecting component changes from 0° to 90°, and the positive projection of the third baffle provided on the second rotating member on the second plane overlaps with the positive projection of the third sensor provided in the second fixed seat on the second plane. After the third sensor senses the third baffle, it transmits a signal to the control device, so that the control device controls the second driving component to stop rotating based on the signal transmitted by the third sensor. At this time, the projector rotates around the z-axis in the second plane to the preset position corresponding to the third projection station under the synchronous drive of the second rotating member and the second connecting component, and the projection of the projection image can be displayed on the second projection screen 52 by the projector at the third projection station.
[0099] It can be understood that, since the adjustment device 100 can control one projector to perform multi-position projection based on the dual pan-tilt platform, the projection system 200 can meet the needs of multiple projection positions in a smaller space. Furthermore, since the projection system 200 can realize multiple projection positions through only one projector, the preparation cost of realizing multiple projection positions can also be reduced.
[0100] It can be understood that since each projection station has calibrated the picture ratio, color gamut and light brightness in advance, it can ensure that the calibrated picture and position information are bound at each projection station, thereby achieving the effect of seamless switching of the projection picture after the projection station changes.
[0101] Different from the prior art, the present application sets a first rotating assembly and a first connecting assembly connected to each other, and a second rotating assembly and a second connecting assembly connected to each other, and makes the end of the first connecting assembly away from the first rotating assembly connected to the second rotating assembly, and makes the end of the second connecting assembly away from the second rotating assembly fixedly connected to the projector, so that when the first rotating assembly is excited and drives the first connecting assembly to rotate around the first axis, the first connecting assembly drives the second rotating assembly and the second connecting assembly to rotate around the first axis, and then drives the projector to rotate synchronously around the first axis through the second connecting assembly, so as to adjust the projector to the preset position of the desired projection station in the first plane, thereby realizing the projection station of the projector in the first plane. Furthermore, when the second rotating assembly is excited and drives the second connecting assembly to rotate around the second axis in the second plane, the second connecting assembly drives the projector to rotate around the second axis, so as to adjust the projector to the preset position of the desired projection station in the second plane, thereby realizing the projection station of the projector in the second plane. The present application adjusts the projection position of the projector in the first plane through the first rotating component, the first connecting component, the second rotating component and the second connecting component, and adjusts the projection position of the projector in the second plane through the second rotating component and the second connecting component. Multiple projection positions can be achieved through one projector, thereby meeting the needs of multiple projection positions in a smaller space.
