[0029] In the prior art, the lifting screen is fixed on the body screen fixing bracket. After the vehicle-mounted projector is fixedly connected to the adapter bracket, the vehicle-mounted projector is fixed by fixing the adapter bracket on the body screen fixing bracket. Among them, the body screen fixing bracket and the body projector bracket are directly welded and fixed on the roof sheet metal. However, due to the influence of factors such as the structural parts of the projector itself and the dimensional tolerances of related structural parts used to install and fix the projector in the car, the projector will form a pitch angle relative to the theoretical installation position, which will cause the picture projected on the screen to shift upward or downward (causing the picture to be not centered), which will then cause a poor viewing experience.
[0030] Based on the above situation, the present application provides a projector adjustment component, which can solve the problem of projection image deviation caused by the pitch angle when the existing projector is installed.
[0031] The projector adjustment component provided in the present application includes: a projector housing, including a first end and a second end arranged opposite to each other, and two side edges arranged opposite to each other connecting the first end and the second end; a first boss and a second boss are arranged on the side edges, the first boss is arranged close to the first end, and the second boss is arranged close to the second end; an adapter, including a first plate body and a second plate body fixedly connected; a first connecting component, which can movably connect the first boss and the first plate body; a second connecting component, which can movably connect the second boss and the second plate body; wherein, when the second connecting component is stimulated, it drives the end of the second plate body away from the first plate body to move in a direction away from or close to the second boss, and when the second plate body moves, it drives the end of the first plate body away from the second plate body to move in a direction close to or away from the first boss, so as to adjust the relative angle between the projector housing and the adapter. The first end of the projector housing and the first plate of the adapter can be movably connected by the first connecting component, and the second end of the projector housing and the second plate of the adapter can be movably connected by the second connecting component. When the second connecting component is stimulated and drives the end of the second plate away from the first plate to move in a direction away from or close to the second boss, the end of the first plate away from the second plate can be driven by the second plate to move in a direction close to or away from the first boss, thereby adjusting the relative angle between the projector housing and the adapter. The present application can adjust the pitch angle of the projector by stimulating the movement of the second connecting component to improve the installation accuracy and projection accuracy of the projector, thereby effectively avoiding the offset of the projection image on the screen, and then meeting the use requirements of the projector in a vehicle environment.
[0032] To illustrate the specific structure of the projector adjustment component of this application, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the assembly structure of the first embodiment of the projector adjustment component of the present application, Figure 2 yes Figure 1 The cross-sectional structure diagram of the projector adjustment component is shown in Figure 1. Figure 3 yes Figure 1 Schematic diagram of the exploded structure of the projector adjustment assembly.
[0033] In this embodiment, the projector adjustment assembly 100 includes a projector housing 10, an adapter 20, a first connecting assembly 30 and a second connecting assembly 40. The projector housing 10 includes a first end 11 and a second end 12 that are arranged opposite to each other, and two opposite sides connecting the first end 11 and the second end 12, and a first boss 101 and a second boss 102 are arranged on the side edges, the first boss 101 is arranged close to the first end 11, and the second boss 102 is arranged close to the second end 12. The adapter 20 includes a first plate body 21 and a second plate body 22 that are fixedly connected. The first connecting assembly 30 can movably connect the first boss 101 and the first plate body 21. The second connecting assembly 40 can movably connect the second boss 102 and the second plate body 22. When the second connecting component 40 is stimulated, it drives the end of the second plate body 22 away from the first plate body 21 to move in a direction away from or close to the second boss 102. When the second plate body 22 moves, it drives the end of the first plate body 21 away from the second plate body 22 to move in a direction close to or away from the first boss 101, so as to adjust the relative angle between the projector housing 10 and the adapter 20.
[0034] In this embodiment, the direction in which the second end 12 points to the first end 11 is the emission direction of the projection light, and the first end 11 is close to the projection lens 15 .
[0035] In this embodiment, the horizontal direction is defined as a direction perpendicular to the extension direction of the screen. When the projection screen is located in the center of the screen, the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is 0°. When the projection screen is biased upward, the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is positive. When the projection screen is biased downward, the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is negative.
[0036] In some embodiments, a first positioning hole 111 is disposed on the first boss 101 , a second positioning hole 112 is disposed on the second boss 102 , and the first boss 101 and the second boss 102 have a first height difference.
[0037] In some embodiments, the adapter 20 includes a first bracket 201 and a plurality of second brackets 202 that are connected to each other. The length direction of the first bracket 201 is parallel to the arrangement direction of the two side edges, and the length of the first bracket 201 is not less than the distance between the two side edges. The plurality of second brackets 202 are symmetrically arranged at both ends of the first bracket 201 extending along the length direction, and the second bracket 202 includes a third plate body 23 and a first plate body 21 and a second plate body 22 arranged at both ends of the third plate body 23, and the extension directions of the first plate body 21 and the second plate body 22 are opposite. The second plate body 22 is connected to the first bracket 201. The first plate body 21 and the second plate body 22 have a second height difference. The second height difference is equal to the first height difference.
[0038] It can be understood that by making the length of the first bracket 201 not less than the distance between the two side edges of the projector housing 10, and making the second height difference between the first plate body 21 and the second plate body 22 equal to the first height difference between the first boss 101 and the second boss 102, when the first bracket 201 is bridged over the projector housing 10, the second brackets 202 at both ends of the first bracket 201 can correspond to the first boss 101 and the second boss 102 extending from the two side edges of the projector housing 10, thereby facilitating the connection between the adapter 20 and the projector housing 10.
[0039] In some embodiments, a first positioning member 210 is disposed on the first plate 21, and a second positioning member 220 is disposed on the second plate 22. The first positioning hole 111 is connected to the first positioning member 210 via a first connecting assembly 30, and the second positioning hole 112 is connected to the second positioning member 220 via a second connecting assembly 40, so that the projector housing 10 is connected to the adapter 20.
[0040] In some specific implementations, the first positioning member 210 and the second positioning member 220 are both nuts, wherein an internal thread is disposed in the nut.
[0041] In some embodiments, a concave first arc surface 21a is provided on the first plate body 21, and the first arc surface 21a is covered with a reinforcing plate 25. A first through hole is provided on the reinforcing plate 25, and a second through hole is provided on the first arc surface 21a, and the first through hole and the second through hole are arranged concentrically. The first positioning member 210 is arranged on the reinforcing plate 25 and is located outside the first through hole. A concave second arc surface 21b is provided on the first boss 101, and the second arc surface 21b is arranged outside the first positioning hole 111. The radius of the second arc surface 21b is not less than the radius of the first arc surface 21a.
[0042] It can be understood that the radius of the second arc surface 21 b is not less than the radius of the first arc surface 21 a , so that the second arc surface 21 b can completely accommodate the first arc surface 21 a .
[0043] In some embodiments, the first connecting assembly 30 includes a first screw, which includes a first screw rod 31 and a first nut 32 disposed at one end of the first screw rod 31, and an external thread is disposed on the first screw rod 31. The diameter of the first screw rod 31 is smaller than the aperture of the first positioning hole 111, and the diameter of the first nut 32 is larger than the aperture of the first positioning hole 111. The first screw rod 31 penetrates the first positioning hole 111, the second through hole, and the first through hole is threadedly matched with the first positioning member 210, so that the first arc surface 21a and the second arc surface 21b are fitted together to connect the first boss 101 and the first plate body 21.
[0044] In some specific embodiments, the first nut 32 is screwed in a clockwise direction to allow the first screw rod 31 to be axially screwed into the first positioning member 210 until the end of the first screw rod 31 away from the first nut 32 extends out of the first positioning member 210, thereby fastening the first boss 101 and the first plate body 21. It can be understood that the more the first screw rod 31 extends out of the first positioning member 210, the better the fastening effect of the first screw, and the more stable the connection between the first boss 101 and the first plate body 21.
[0045] In other specific embodiments, the first nut 32 is twisted counterclockwise to rotate the first screw 31 axially out of the first positioning member 210 until the end of the first screw 31 away from the first nut 32 is separated from the first positioning member 210, thereby releasing the connection between the first boss 101 and the first plate 21. It can be understood that the less the portion where the first screw 31 and the first positioning member 210 form a threaded fit, the worse the fastening effect of the first screw, and the looser the connection between the first boss 101 and the first plate 21.
[0046] It can be understood that when the first screw 31 is connected to the first positioning member 210, and the end of the first screw 31 away from the first nut 32 does not extend out of the first positioning member 210 or the portion extending out of the first positioning member 210 is small, the connection relationship between the first boss 101 and the first plate body 21 formed by the first connecting assembly 30 is a movable connection, and the first arc surface 21a of the first plate body 21 can slide circumferentially within the second arc surface 21b.
[0047] In some embodiments, the second positioning hole 112 is provided with an internal thread, and the second connecting component 40 includes a hollow transmission member 41, and the outer side of the hollow transmission member 41 is provided with an external thread. The hollow transmission member 41 passes through the second positioning hole 112, and the external thread of the hollow transmission member 41 is used to cooperate with the internal thread in the second positioning hole 112 to achieve thread transmission. The second connecting component 40 also includes a second screw 42, and the second screw 42 includes a second screw rod 421 and a second nut 422 disposed at one end of the second screw rod 421, and the second screw rod 421 is provided with an external thread. Among them, the diameter of the second screw rod 421 is smaller than the inner side hole diameter of the hollow transmission member 41, and the diameter of the second nut 422 is larger than the inner side hole diameter of the hollow transmission member 41. Among them, the second screw rod 421 passes through the hollow transmission member 41 and is threadedly matched with the second positioning member 220 to connect the second boss 102 and the second plate body 22.
[0048] It can be understood that the second screw rod 421 is only used to penetrate the hollow transmission member 41 , but has no fixed connection relationship with the hollow transmission member 41 . The second screw rod 421 only forms a threaded fit with the second positioning member 220 , thereby forming a fixed connection with the second plate body 22 .
[0049] In this embodiment, when the connection relationship formed between the first boss 101 and the first plate body 21 through the first connecting assembly 30 is a movable connection, the hollow transmission member 41 is rotated to rotate in or out axially in the second positioning hole 112, and when the hollow transmission member 41 moves, it drives the second screw 42 and the second positioning member 220 to move in a direction away from or close to the second boss 102, so that the end of the second plate body 22 away from the first plate body 21 moves in a direction away from or close to the second boss 102. When the second plate body 22 moves, the first arc surface 21a of the first plate body 21 is driven to rotate downward or upward along the circumferential direction on the second arc surface 21b, so that the end of the first plate body 21 away from the second plate body 22 moves in a direction close to or away from the first boss 101, so as to adjust the relative angle between the projector housing 10 and the adapter 20.
[0050] In a specific implementation scenario, after the projector housing 10 and the adapter 20 are installed through the first connecting component 30 and the second connecting component 40, if it is observed that the projection image projected by the projector onto the screen is biased upward (the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is positive), the first connecting component 30 is loosened to form a movable connection between the first boss 101 and the first plate 21 through the first connecting component 30. Then, the hollow transmission member 41 is rotated to make the hollow transmission member 41 screw inward axially in the second positioning hole 112. When the hollow transmission member 41 moves, it drives the second screw 42 and the second positioning member 220 to move in a direction away from the second boss 102, so that the end of the second plate 22 away from the first plate 21 moves in a direction away from the second boss 102. When the second plate 22 moves, the first arc surface 21a of the first plate 21 is driven to rotate downward along the circumference on the second arc surface 21b, so that the end of the first plate 21 away from the second plate 22 moves in a direction close to the first boss 101, thereby adjusting the relative angle between the projector housing 10 and the adapter 20. The hollow transmission member 41 is continuously rotated to continuously reduce the pitch angle formed by the emission direction of the projection light and the horizontal direction. In this process, the projection picture gradually moves downward. When the projection picture is adjusted to be located in the center of the screen, the rotation of the hollow transmission member 41 is stopped. At this time, the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is 0°. Finally, the first connecting assembly 30 is tightened again to fix the projector housing 10 and the adapter 20 .
[0051] In another specific implementation scenario, after the projector housing 10 and the adapter 20 are installed through the first connecting component 30 and the second connecting component 40, if it is observed that the projection image projected by the projector onto the screen is biased downward (the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is negative), loosen the first connecting component 30 to form a movable connection between the first boss 101 and the first plate 21 through the first connecting component 30. Then, the hollow transmission member 41 is rotated to make the hollow transmission member 41 rotate out axially in the second positioning hole 112. When the hollow transmission member 41 moves, it drives the second screw 42 and the second positioning member 220 to move in the direction close to the second boss 102, so that the end of the second plate 22 away from the first plate 21 moves in the direction close to the second boss 102. When the second plate 22 moves, the first arc surface 21a of the first plate 21 is driven to rotate upward along the circumferential direction on the second arc surface 21b, so that the end of the first plate 21 away from the second plate 22 moves in the direction away from the first boss 101, thereby adjusting the relative angle between the projector housing 10 and the adapter 20. The hollow transmission member 41 is continuously rotated to continuously reduce the pitch angle formed by the emission direction of the projection light and the horizontal direction. In this process, the projection picture gradually moves upward. When the projection picture is adjusted to be located in the center of the screen, the rotation of the hollow transmission member 41 is stopped. At this time, the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is 0°. Finally, the first connecting assembly 30 is tightened again to fix the projector housing 10 and the adapter 20 .
[0052] In the above specific implementation scenario, after re-tightening the first connecting component 30 , check whether the second connecting component 40 is loose. If it is loose, tighten the second screw 42 to tighten the connection between the second screw 42 and the second plate 22 .
[0053] It can be understood that this embodiment can adjust the pitch angle of the projector by stimulating the movement of the second connecting component 40 to improve the installation accuracy and projection accuracy of the projector, thereby effectively avoiding the deviation of the projected image on the screen, and then meeting the use requirements of the projector in a vehicle environment.

The projector housing 10 includes a first end 11 and a second end 12 that are arranged opposite to each other, and two opposite sides that connect the first end 11 and the second end 12, and a first boss 101 and a second boss 102 are arranged on the side edges, the first boss 101 is arranged close to the first end 11, and the second boss 102 is arranged close to the second end 12.

The first connecting assembly 30 can movably connect the first boss 101 and the first plate body 21. The second connecting assembly 40 can movably connect the second boss 102 and the second plate body 22. When the second connecting component 40 is stimulated, it drives the end of the second plate body 22 away from the first plate body 21 to move in a direction away from or close to the second boss 102. When the second plate body 22 moves, it drives the end of the first plate body 21 away from the second plate body 22 to move in a direction close to or away from the first boss 101, so as to adjust the relative angle between the projector housing 10 and the adapter 20.
[0056] Only the parts of this embodiment that are different from the first embodiment will be described below.
[0057] In this embodiment, the first connecting component 30 includes a first stud 51 and a first spring 61 sleeved on the periphery of the first stud. The first stud 51 includes a first step shaft 511 and a second step shaft 512, and a first flange 513 is provided at one end of the second step shaft 512 away from the first step shaft 511, and an external thread is provided on the first step shaft 511. The diameter of the first step shaft 511 is smaller than the diameter of the second step shaft 512, the diameter of the second step shaft 512 is smaller than the diameter of the first positioning hole 111, and the diameter of the first flange 513 is larger than the diameter of the first positioning hole 111. The first stud 51 passes through the first positioning hole 111, and the first step shaft 511 is threadedly matched with the first positioning member 210 to connect the first boss 101 and the first plate body 21. The two ends of the first spring 61 abut the first boss 101 and the first plate body 21 respectively.
[0058] It can be understood that only the first step shaft 511 in the first connecting component 30 is used for fixed connection with the first plate body 21. Since the diameter of the second step shaft 512 is smaller than the diameter of the first positioning hole 111, the second step shaft 512 can move up and down in the first positioning hole 111. The second step shaft 512 is then limited by the first flange 513 so that it will not separate from the first positioning hole 111, thereby realizing the movable connection between the first boss 101 and the first plate body 21.
[0059] In some embodiments, the first spring 61 has a relatively large elastic force value, and after being compressed, the first boss 101 abutting against it is subjected to the elastic force and generates acceleration. In some specific embodiments, the first boss 101 is subjected to the elastic force and generates an acceleration greater than 35.5g / s 2 .
[0060] It can be understood that by limiting the elastic force range of the first spring 61 and the length range of the second step shaft 512 , the movable stroke of the second step shaft 512 in the first positioning hole 111 can be controlled.
[0061] In this embodiment, the second connecting component 40 includes a second stud 52 and a second spring 62 sleeved on the outer periphery of the second stud 52. The second stud 52 includes a second column 521 and a second flange 522 arranged at one end of the second column 521, and the second column 521 is provided with an external thread. The diameter of the second column 521 is smaller than the aperture of the second positioning hole 112, and the diameter of the second flange 522 is larger than the aperture of the second positioning hole 112. The second stud 52 penetrates the second positioning hole 112 and is threadedly matched with the second positioning member 220 to connect the second boss 102 and the second plate 22. The two ends of the second spring 62 abut the second boss 102 and the second plate 22 respectively.
[0062] The second screw 52 can be screwed out or screwed in axially in the second positioning member 220 by screwing the second screw 52 to extend out of the second column 521 of the second positioning member 220 .
[0063] In some embodiments, the second spring 62 has a relatively large elastic force value, and after being compressed, the second boss 102 abutting against it is subjected to the elastic force and generates acceleration. In some specific embodiments, the acceleration generated by the elastic force on the second boss 102 is greater than 35.5g / s 2 .
[0064] It can be understood that by limiting the elastic force range of the second spring 62 and the length range of the second column 521 , the movable stroke of the second column 521 in the second positioning hole 112 can be controlled.
[0065] In this embodiment, when the second stud 52 is screwed, it is screwed out or screwed in axially in the second positioning member 220, so that the end of the second plate body 22 away from the first plate body 21 moves in a direction away from or close to the second boss 102. When the second plate body 22 moves, the end of the first plate body 21 away from the second plate body 22 is driven to move in a direction close to or away from the first boss 101 to adjust the relative angle between the projector housing 10 and the adapter 20.
[0066] In a specific implementation scenario, after the projector housing 10 and the adapter 20 are installed through the first connecting component 30 and the second connecting component 40, if it is observed that the projection image projected by the projector onto the screen is biased upward (the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is positive), the second stud 52 is screwed to extend the second column 521 of the second positioning member 220, so that the second stud 52 is axially screwed out in the second positioning member 220, so that the end of the second plate 22 away from the first plate 21 moves in a direction away from the second boss 102, and the second plate 22 drives the end of the first plate 21 away from the second plate 22 to move in a direction close to the first boss 101 when the second plate 22 moves, so as to adjust the relative angle between the projector housing 10 and the adapter 20. The second stud 52 is continuously screwed to continuously reduce the pitch angle formed by the projection light emission direction and the horizontal direction, and the projection image gradually moves downward during this process. When the projection image is adjusted to be located in the center of the screen, the second screw 52 is stopped from being screwed. At this time, the pitch angle formed between the projection light emitted by the projection lens 15 and the horizontal direction is 0°.
[0067] In another specific implementation scenario, after the projector housing 10 and the adapter 20 are installed through the first connecting component 30 and the second connecting component 40, if it is observed that the projection image projected by the projector onto the screen is downward (the pitch angle formed by the projection light emitted by the projection lens 15 and the horizontal direction is negative), the second stud 52 is screwed to extend the second column 521 of the second positioning member 220, so that the second stud 52 is screwed axially in the second positioning member 220, so that the end of the second plate 22 away from the first plate 21 moves in a direction close to the second boss 102, and the second plate 22 drives the end of the first plate 21 away from the second plate 22 to move in a direction away from the first boss 101 when the second plate 22 moves, so as to adjust the relative angle between the projector housing 10 and the adapter 20. The second stud 52 is continuously screwed to continuously reduce the pitch angle formed by the emission direction of the projection light and the horizontal direction, and the projection image gradually moves upward during this process. When the projection image is adjusted to be located in the center of the screen, the second screw 52 is stopped from being screwed. At this time, the pitch angle formed between the projection light emitted by the projection lens 15 and the horizontal direction is 0°.
[0068] In some embodiments, the first boss 101 is provided with a first through hole 71, and the second boss 102 is provided with a second through hole 72. The projector adjustment assembly 200 further includes a first support column 81 and a second support column 82. The first support column 81 passes through the first through hole 71, and one end of the first support column 81 abuts against the first plate 21. The second support column 82 passes through the second through hole 72, and one end of the second support column 82 abuts against the second plate 22.
[0069] In some embodiments, the first through hole 71 and the second through hole 72 are both provided with internal threads, the outer sides of the first support column 81 and the second support column 82 are both provided with external threads, the first support column 81 passes through the first through hole 71 and forms a threaded fit with the first through hole 71, and the second support column 82 passes through the second through hole 72 and forms a threaded fit with the second through hole 72.
[0070] In some other implementations, the first via hole 71 forms an interference fit with the first support column 81 , and the second via hole 72 forms an interference fit with the second support column 82 , which is not limited in the present application.
[0071] In some embodiments, without affecting assembly, the first via hole 71 can be set as close to the first positioning hole 111 as possible, and the second via hole 72 can be set as close to the second positioning hole 112 as possible, so that the first support column 81 is set close to the first stud 51, and the second support column 82 is set close to the second stud 52.
[0072] It can be understood that after the projection image is adjusted, the projector housing 10 and the adapter 20 are locked by the first support column 81 and the second support column 82 , so as to improve the stability of the projection system.
[0073] In some implementations, after assembling the first support column 81 and the second support column 82 , glue may be dispensed in the first positioning hole 111 , the second positioning hole 112 , the first through hole 71 , and the second through hole 72 to further improve the stability of the projection system.
[0074] In other embodiments, if the assembly space in the vehicle is limited, the first support column 81 and the second support column 82 may be omitted.
[0075] In the above embodiment, only the first stud 51 in the first connecting assembly 30 is a stepped stud. In other embodiments, the second stud 52 in the second connecting assembly 40 may be a stepped stud, while the first stud 51 may be a non-stepped stud. The first stud 51 and the second stud 52 may also be both stepped studs, which is not limited in the present application.
[0076] It can be understood that the above-mentioned multiple components have simple structures and sophisticated coordination, high reliability, simple manufacturing and assembly processes, low preparation costs, and the ability to be mass-produced.
[0077] Different from the prior art, the present application can flexibly connect the first end of the projector housing and the first plate of the adapter through a first connecting component, and can flexibly connect the second end of the projector housing and the second plate of the adapter through a second connecting component. When the second connecting component is stimulated and drives the end of the second plate away from the first plate to move in a direction away from or close to the second boss, the end of the first plate away from the second plate can be driven by the second plate to move in a direction close to or away from the first boss, thereby adjusting the relative angle between the projector housing and the adapter. By stimulating the movement of the second connecting component, the present application can adjust the pitch angle of the projector to improve the installation accuracy and projection accuracy of the projector, thereby effectively avoiding the offset of the projected image on the screen, and then meeting the use requirements of the projector in a vehicle-mounted environment.
[0078] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
