[0002] Projection optical machines often use devices such as DMD (digital micromirror device), LCD (Liquid Crystal Display), LCOS (Liquid Crystal On Silicon) as spatial light modulation devices. In order to maximize the light efficiency and avoid abnormal edge leakage in the display screen, the overfill (overfill is the ratio of the light spot power outside the panel to the total light spot power at the panel) is often set to 110%~120% as a leakage adjustment margin.

[0003] At present, the leakage edge adjustment component generally sets an adjustable reflector between the compound eye lens and the prism to adjust the light after the compound eye homogenization and shaping. However, in the case of insufficient space, the compound eye and the prism cannot be folded. In the prior art, it is usually necessary to adjust the leakage edge by adjusting the lens between the compound eye and the prism, that is, to simultaneously control the displacement of the lens in the x direction (horizontal direction) and the y direction (vertical direction) through the lens adjustment bracket, so that the effective light spot completely covers the effective area of ​​the spatial light modulator.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0031] In the prior art, the leakage edge is usually adjusted by adjusting the lens between the compound eye and the prism, that is, the displacement of the lens in the x direction (horizontal direction) and the y direction (vertical direction) is controlled simultaneously by the lens adjustment bracket, so that the effective light spot completely covers the effective area of ​​the spatial light modulator. However, the existing lens adjustment bracket needs to be adjusted with the help of a multi-axis fixture, which has a complex structure, is difficult to prepare, and is also difficult to adjust.

[0032] Based on the above situation, the present application provides an optical adjustment component and an optical-mechanical component, which can solve the problems of complex structure and difficult adjustment in existing leakage edge adjustment devices.

[0033] The optical adjustment component provided in the present application includes: a compound eye frame; a connecting component, connected to the compound eye frame and slidable relative to the compound eye frame along a first direction; wherein the connecting component is provided with a first accommodating space; a hollow eccentric component, accommodated in the first accommodating space, and rotatable relative to the connecting component in the plane where the first accommodating space is located; a lens, arranged in the hollow area of ​​the hollow eccentric component; wherein, when the connecting component slides along the first direction, the hollow eccentric component is driven to reciprocate along the first direction to adjust the displacement of the lens center in the first direction; when the hollow eccentric component rotates relative to the connecting component, the lens is driven to reciprocate in the second direction to adjust the displacement of the lens center in the second direction; wherein the second direction is perpendicular to the first direction. By providing a connecting component that is slidably connected to the compound eye frame, and accommodating the hollow eccentric component provided with the lens in the first accommodating space of the connecting component, the hollow eccentric component can be driven to reciprocate in the first direction by the sliding of the connecting component, thereby adjusting the displacement of the center of the lens in the first direction; and then by rotating the hollow eccentric component in the first accommodating space, the center of the lens can be driven to reciprocate in the second direction, thereby adjusting the displacement of the center of the lens in the second direction. The present application realizes horizontal displacement through the connecting component, and converts the rotation angle of the hollow eccentric component into vertical displacement, and can realize leakage edge adjustment in two directions without the need for a multi-axis fixture, thereby not only reducing the structural complexity of the optical adjustment component, but also reducing the difficulty of leakage edge adjustment, thereby reducing the preparation cost and improving the convenience of adjustment.

[0034] To illustrate the specific structure of the optical 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 optical adjustment component of the present application, Figure 2 yes Figure 1 Schematic diagram of the three-dimensional structure after the optical adjustment component is rotated 180°. Figure 3 yes Figure 1 Top view of the optical adjustment component.

[0035] In this embodiment, the optical adjustment component 100 includes a compound eye frame 10, a connecting component 20, a hollow eccentric component 30 and a lens 40. The connecting component 20 is connected to the compound eye frame 10 and can slide relative to the compound eye frame 10 along a first direction x. The connecting component 20 is provided with a first accommodating space. The hollow eccentric component 30 is accommodated in the first accommodating space and can rotate relative to the connecting component 20 in the plane where the first accommodating space is located. The lens 40 is arranged in the hollow area of ​​the hollow eccentric component 30. When the connecting component 20 slides along the first direction x, the hollow eccentric component 30 is driven to reciprocate along the first direction x to adjust the displacement of the center of the lens 40 in the first direction x. When the hollow eccentric component 30 rotates relative to the connecting component 20, the lens 40 is driven to reciprocate in the second direction y to adjust the displacement of the center of the lens 40 in the second direction y. The second direction y is perpendicular to the first direction x.

[0036] In this embodiment, the first direction x is a horizontal direction, that is, a left-right direction of the display screen, and the second direction y is a vertical direction, that is, a top-bottom direction of the display screen.

[0037] Please refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 7 . Figure 4 yes Figure 1 Schematic diagram of the structure of the meso-compound eye frame. Figure 5 yes Figure 1 Schematic diagram of the structure of the connection components. Figure 6 yes Figure 1 Schematic diagram of the structure of the hollow eccentric component. Figure 7 yes Figure 6 Schematic cross-section of the hollow eccentric component.

[0038] like Figure 4 As shown, in this embodiment, the compound eye frame 10 includes an incident surface and an exit surface that are arranged oppositely, and the incident surface is used to install the compound eye lens 50. Bosses 11 are symmetrically arranged on the edges of the opposite sides of the exit surface, and a limiting column 12 is arranged on the top surface of the boss 11. The arrangement direction of the bosses is the first direction, and the extension direction of the limiting column is the second direction.

[0039] In some embodiments, the incident surface includes a first supporting surface 101 and a second supporting surface 102, the first supporting surface 101 is bonded to the first side surface of the fly-eye lens 50, and the second supporting surface 102 is bonded to the second side surface of the fly-eye lens 50. In some specific embodiments, the incident surface includes two first supporting surfaces 101, which are respectively arranged at the opposite side edges of the incident surface, and the second supporting surface 102 is arranged at the bottom end of the incident surface.

[0040] In some embodiments, glue dispensing grooves 13 are provided on the first supporting surface 101 and the second supporting surface 102. After the compound eye lens 50 is installed, glue is dispensed in the plurality of glue dispensing grooves 13 so that the first supporting surface 101 and the second supporting surface 102 are respectively bonded to the first side surface and the second side surface of the compound eye lens 50, thereby fixing the compound eye lens 50 on the compound eye frame 10.

[0041] In some embodiments, the compound eye frame 10 is provided with a plurality of positioning holes 14 and a plurality of fixing holes 15. The positioning holes 14 are used for positioning with the optical machine housing, and the fixing holes 15 are used for cooperating with fixing parts to connect the compound eye frame 10 with the optical machine housing.

[0042] In some specific implementations, a positioning column that cooperates with the positioning hole 14 is provided on the optical machine housing. After high-precision positioning is achieved through the cooperation between the positioning column and the positioning hole 14, the locking screw is inserted into the fixing hole 15 to connect the compound eye frame 10 to the optical machine housing.

[0043] like Figure 5 As shown, in this embodiment, the connection assembly 20 includes a support plate 21 and two extensions 22. The support plate 21 is a square plate with a hollow circular area, and the hollow circular area corresponds to the hollow area of ​​the hollow eccentric assembly. The extensions 22 are symmetrically arranged on the opposite side edges of the support plate 21 and extend to the outside of the support plate 21. The extensions 22 include an annular slot 23, the length direction of the annular slot 23 is parallel to the first direction x, and the width of the annular slot 23 is equal to the diameter of the limit column 12.

[0044] In other embodiments, the width of the annular slot 23 may be slightly larger than the diameter of the limiting column 12 to facilitate the limiting column 12 to slide in the annular slot 23 , which is not limited in the present application.

[0045] Among them, the support plate 21 is fitted with the exit surface of the compound eye frame 10, the bottom surface of the extension part 22 is abutted with the top surface of the boss 11, and the limiting column 12 is sleeved in the annular groove 23 of the extension part 22 so that the limiting column 12 slides along the annular groove 23 relative to the connecting component 20.

[0046] Among them, a countersunk hole is provided in the annular groove 23 as a glue flow space during glue dispensing. After the relative position between the limiting column 12 and the annular groove 23 is adjusted, glue can be dispensed in the annular groove 23 to fix the connection component 20 and the compound eye frame 10.

[0047] It can be understood that the bottom surface of the extension 22 abuts against the top surface of the boss 11, which can limit the movement of the connecting assembly 20 in the second direction y. The limiting column 12 is sleeved in the annular slot 23, and because the width of the annular slot 23 is equal to the diameter of the limiting column 12, the limiting column 12 can be prevented from moving along the third direction z, so that the limiting column 12 can only move along the first direction x. The third direction z is perpendicular to the first direction x and the second direction y.

[0048] It can be understood that, through the connection between the extension portion 22, the boss 11 and the limiting column 12, the freedom of the connecting component 20 in the second direction y and the third direction z can be limited so that it can only move along the first direction x, thereby accurately realizing the displacement adjustment of the lens 40 in the first direction x.

[0049] Continue reading Figure 5 In this embodiment, the connection assembly 20 includes a limiting assembly, and the limiting assembly includes a first limiting portion 201, a second limiting portion 202 and a first side wall 203.

[0050] The first limiting portion 201 is arranged along a portion of the edge of the hollow circular area and is connected to the portion of the extension portion 22 located on the support plate 21. The first side wall 203 is connected to the outer edge of the first limiting portion 201, and the end of the first side wall 203 away from the first limiting portion 201 is connected to the second limiting portion 202. The orthographic projection of the outer edge of the second limiting portion 202 on the support plate 21 overlaps with the orthographic projection of the outer edge of the first limiting portion 201 on the support plate 21. The orthographic projection of the inner edge of the second limiting portion 202 on the support plate 21 is located within the orthographic projection of the inner edge of the first limiting portion 201 on the support plate 21.

[0051] The first limiting portion 201 , the second limiting portion 202 and the first side wall 203 cooperate to form a first accommodating space.

[0052] In some embodiments, the connection assembly 20 includes a protrusion 24, and the protrusion 24 is located at a side edge of the support plate 21 where no limit assembly is provided. It can be understood that by providing the protrusion 24, it is convenient for the user to adjust the relative position between the connection assembly 20 and the compound eye frame 10, thereby facilitating the adjustment of the displacement of the lens 40 in the first direction x.

[0053] like Figure 6 and Figure 7 As shown, in this embodiment, the hollow eccentric component 30 includes a hollow frame 31, a second side wall 32 and an annular hook 33. The hollow frame 31 includes a semicircular ring 311 and an eccentric semicircular ring 312 connected to each other, the inner ring of the eccentric semicircular ring 312 is spliced ​​with the inner ring of the semicircular ring 311 to form the inner ring of the hollow frame 31, the inner ring of the hollow frame 31 is circular, and the outer ring of the eccentric semicircular ring 312 is an eccentric arc.

[0054] Among them, the eccentric distance from each point on the eccentric arc to the center of the inner circle is different, and the eccentric distance gradually increases.

[0055] The second side wall 32 is connected to the inner ring edge of the hollow frame 31, and an annular hook 33 is provided at one end of the second side wall 32 away from the hollow frame 31. The second side wall 32 cooperates with the annular hook 33 to form a second accommodating space.

[0056] The second side wall 32 is used to cooperate with the inner edge gap of the first limiting portion 201 , the outer ring edge of the hollow frame 31 is used to cooperate with the first side wall 203 , and the side surface of the hollow frame 31 away from the second side wall 32 is in contact with the second limiting portion 202 .

[0057] It can be understood that the clearance fit between the second side wall 32 and the first limiting portion 201 can limit the degree of freedom of the hollow eccentric component 30 in the first direction x without affecting the rotation of the hollow eccentric component 30. Similarly, the side surface of the hollow frame 31 away from the second side wall 32 is in contact with the second limiting portion 202, which can limit the movement of the hollow eccentric component 30 in the third direction z, thereby accurately achieving the displacement adjustment of the lens 40 in the second direction y.

[0058] The hollow eccentric component 30 includes a shifting tooth 34, which is located at the outer ring edge of the semicircular ring 311 and extends to the outside of the hollow frame 31. It can be understood that by providing the shifting tooth 34, it is convenient for the user to rotate the hollow eccentric component 30 to convert the rotation angle of the hollow eccentric component 30 into the displacement of the lens 40 in the vertical direction, thereby facilitating the adjustment of the displacement of the lens 40 in the second direction y.

[0059] Combined with reference Figure 5 The first side wall 203 has a first limiting surface 2031 and a second limiting surface 2032 intersecting each other. The second limiting surface 2032 is disposed at the bottom of the first side wall 203 away from the extension portion 22, one end of the first limiting surface 2031 is connected to the second limiting surface 2032, and the other end is connected to the portion of the extension portion 22 located on the support plate 21. The connection A between the first limiting surface 2031 and the second limiting surface 2032 is used to abut against the eccentric arc, and the second limiting surface 2032 is used to cooperate with a side edge 35 of the shifting tooth 34.

[0060] Among them, the edge 35 is connected to the eccentric arc with the minimum eccentric distance to form a rotation limit surface, that is, when the hollow eccentric component 30 is rotated along a certain direction until the edge 35 abuts against the second limit surface 2032, the hollow eccentric component 30 can no longer be rotated in the same direction.

[0061] When the hollow eccentric component 30 is rotated, the eccentric arc always abuts against the connection A between the first limiting surface 2031 and the second limiting surface 2032, and as the eccentric distance corresponding to the eccentric arc abutting against the connection A increases, the distance between the lens center and the connection A becomes farther and farther.

[0062] Please refer to Figure 8 , Figure 8 It is a schematic diagram of the connection between the hollow eccentric component and the connecting component when rotating at different angles. In this embodiment, the left figure is a figure when the rotation limit surface of the shifting tooth abuts against the second limit surface; the hollow eccentric component in the left figure is rotated 90° clockwise to obtain the middle figure; the hollow eccentric component in the middle figure is further rotated 90° clockwise to obtain the right figure.

[0063] Specifically, the cross point is the center of the lens, and when the rotation limit surface of the shifting tooth (one side edge of the shifting tooth) abuts against the second limit surface (left figure), the distance between the center of the lens and the connection A is the shortest. When the hollow eccentric assembly is rotated clockwise, as the rotation angle increases, the distance between the center of the lens and the connection A gradually increases, thereby achieving the purpose of adjusting the displacement of the center of the lens in the second direction y.

[0064] In this embodiment, the lens 40 is first accommodated in the second accommodation space of the hollow eccentric component 30, and then the hollow eccentric component 30 is accommodated in the first accommodation space of the connecting component 20. Then, the limiting column 12 of the compound eye frame 10 is sleeved in the annular slot 23 of the connecting component 20, and the protrusion 24 is pushed to make the limiting column 12 slide in the annular slot 23, and the hollow eccentric component 30 is driven to reciprocate along the first direction x, so as to adjust the displacement of the center of the lens 40 in the first direction x. After the displacement in the first direction x is adjusted, glue is dispensed in the annular slot 23 to fix the connecting component 20 and the compound eye frame 10. Then, the wave gear 34 is used to rotate the hollow eccentric component 30 relative to the connecting component 20, and the lens 40 is driven to reciprocate in the second direction y, so as to adjust the displacement of the center of the lens 40 in the second direction y.

[0065] It can be understood that, in this embodiment, by providing a connecting assembly 20 that is slidably connected to the compound eye frame 10, and accommodating the hollow eccentric assembly 30 provided with the lens 40 in the first accommodation space of the connecting assembly 20, the sliding of the connecting assembly 20 can drive the hollow eccentric assembly 30 to reciprocate along the first direction x, thereby adjusting the displacement of the center of the lens 40 in the first direction x. Furthermore, by rotating the hollow eccentric assembly 30 in the first accommodation space, the center of the lens 40 can be driven to reciprocate in the second direction y, thereby adjusting the displacement of the center of the lens 40 in the second direction y.

[0066] It can be understood that the number of the above-mentioned parts is small, the design of the parts is simple and the coordination is exquisite, and the decoupling adjustment in two directions can be achieved without the need for elastic adjustment structures such as springs and screws, thereby not only improving the process efficiency and reducing the preparation cost, but also simplifying the adjustment process.

[0067] Different from the prior art, this embodiment realizes horizontal displacement through the connecting component 20, and converts the rotation angle of the hollow eccentric component 30 into vertical displacement. It can realize leakage edge adjustment in two directions without the need for a multi-axis fixture, thereby reducing not only the structural complexity of the optical adjustment component 100, but also the difficulty of leakage edge adjustment, thereby reducing the preparation cost and improving the convenience of adjustment.

[0068] Correspondingly, the present application provides an optical-mechanical assembly.

[0069] Specifically, see Fig. 9 , Fig. 9 1 is a schematic diagram of the structure of an embodiment of an optical-mechanical assembly of the present application. In this embodiment, the optical-mechanical assembly 200 includes an optical-mechanical body, an optical-mechanical housing, and the optical adjustment assembly 100 described above.

[0070] In this embodiment, the optical machine body includes a spatial light modulator 60, a prism 70 and an optical lens 80. The spatial light modulator 60 is fixed to the optical machine housing and is an optical device that modulates the illumination light into a desired image. The prism 70 is fixed to the optical machine housing and is arranged opposite to the spatial light modulator 60, and is used to reflect / refract / project the light reflected or projected by the spatial light modulator 60 into the lens. The optical lens 80 is arranged on the side of the prism 70 away from the spatial light modulator 60 and is fixed to the optical machine housing, and together with the lens in the optical adjustment component 100, it constitutes the optical light path behind the compound eye lens 50.

[0071] The spatial light modulator 60 includes a light modulator effective surface 61 and a light modulator central axis 62 , and the light modulator effective surface 61 is used to display an effective light spot.

[0072] Please refer to Fig.10 , Fig.10 1 is a diagram showing the change of the optical path when the displacement adjustment in the first direction is performed. In this embodiment, the positions of the prism 70 and the optical lens 80 remain unchanged. When the lens in the optical adjustment assembly 100 is adjusted in the first direction x, the light passing through the lens is angularly offset, resulting in the synchronous displacement of the light spot finally hitting the spatial light modulator 60, thereby achieving the leakage edge adjustment in the first direction x. Similarly, the leakage edge adjustment in the second direction y can be referred to.

[0073] Different from the prior art, the present application sets a connection component that is slidably connected to the compound eye frame, and accommodates the hollow eccentric component provided with the lens in the first accommodation space of the connection component. The sliding of the connection component can drive the hollow eccentric component to reciprocate in the first direction, thereby adjusting the displacement of the center of the lens in the first direction; and then the rotation of the hollow eccentric component in the first accommodation space can drive the center of the lens to reciprocate in the second direction, thereby adjusting the displacement of the center of the lens in the second direction. The present application realizes horizontal displacement through the connection component, and converts the rotation angle of the hollow eccentric component into vertical displacement. It can realize leakage edge adjustment in two directions without the need for a multi-axis fixture, thereby not only reducing the structural complexity of the optical adjustment component, but also reducing the difficulty of leakage edge adjustment, thereby reducing the preparation cost and improving the convenience of adjustment.

[0074] 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.
