[0035] Please see Figure 1 and Figure 2 This invention provides a mounting structure for an optical component, including a bracket 100. A first component mounting position 110 and a second component mounting position 120 are disposed opposite each other on the bracket 100. The first component mounting position 110 is provided with a first positioning mechanism 112 for positioning a first compound eye lens, and the second component mounting position 120 is provided with a second positioning mechanism 121 for positioning a second compound eye lens. The first positioning mechanism 112 includes a first X-direction positioning boss 1121 and a first Y-direction positioning boss 1123, and the second positioning mechanism 121 includes a second X-direction positioning boss 1212 and a second Y-direction positioning boss 1214. The first X-direction positioning boss 1121 and the second X-direction boss are disposed on the Y-direction edge of the bracket and protrude in the X-direction, and the first Y-direction positioning boss 1123 and the second Y-direction boss are disposed on the X-direction edge of the bracket and protrude in the Y-direction. The XYZ coordinate system is as follows: Figure 1As shown in the figure, the first X-direction positioning boss 1121 and the second X-direction positioning boss 1212, and the first Y-direction positioning boss 1123 and the second Y-direction positioning boss 1214 are in the same position and have the same size. The first X-direction positioning boss 1121 and the second X-direction positioning boss 1212 can be machined in one go at the same station with the same tool, and the first Y-direction positioning boss 1123 and the second Y-direction positioning boss 1214 can be machined in one go at the same station with the same tool.

[0036] In this embodiment, there are two of each of the first X-direction positioning boss 1121 and the second X-direction positioning boss 1212. The two first X-direction positioning bosses 1121 are respectively arranged on two opposite edges of the first positioning mechanism of the bracket in the Y direction, and the two second X-direction positioning bosses 1212 are respectively arranged on two opposite edges of the second positioning mechanism of the bracket in the Y direction. There are also two of each of the first Y-direction positioning bosses 1123 and the second Y-direction positioning bosses 1214. The two first Y-direction positioning bosses 1123 are respectively arranged on two opposite edges of the first positioning mechanism of the bracket in the X direction, and the two second Y-direction positioning bosses 1214 are respectively arranged on two opposite edges of the second positioning mechanism of the bracket in the X direction.

[0037] In other embodiments, there are four positioning bosses: the first X-direction positioning boss 1121, the second X-direction positioning boss 1212, the first Y-direction positioning boss 1123, and the second Y-direction positioning boss 1214, which are arranged in pairs opposite to each other. That is, two positioning bosses are respectively provided on the X-direction edge and the Y-direction edge of the first positioning mechanism and the second positioning mechanism of the bracket.

[0038] Specifically, the bracket 100 is generally a rectangular frame structure with a hollow center. The bracket 100 can be used to position optical elements to form a functional assembly. The bracket 100 includes an inner wall 101, an outer wall 102, a top wall 103, and a bottom wall 104, wherein the inner wall 101 and the outer wall 102 are opposite to each other. In this embodiment, the housing has at least one opening penetrating the inner wall 101 and the outer wall 102 to facilitate heat dissipation of the first compound eye lens 20 or PCS60. The inner wall 101 and the outer wall 102 can also be used for mounting the bracket 100. A first X-direction positioning boss 1121 and a second X-direction boss protrude from the inner wall 101 along the X-direction, and a first Y-direction positioning boss 1123 and a second Y-direction boss protrude from the inner wall 101 along the Y-direction. The outer wall 102 of the bracket 100 is provided with a buckle 1021. The buckle 1021 can be a male buckle protruding from the outer wall 102 or a female buckle recessed from the outer wall 102. The specific structure can be set according to the actual situation. The top wall 103 and the bottom wall 104 are opposite to each other, and the inner wall 101 connects the top wall 103 and the bottom wall 104. The inner wall 101 includes four corners. In this embodiment, both the top wall 103 and the bottom wall 104 have openings to facilitate the mounting of optical elements from the top wall 103 and the bottom wall 104 onto the bracket 100.

[0039] The bracket 100 also includes a mounting surface 105, which is located between the top wall 103 and the bottom wall 104. In this embodiment, the mounting surface 105 may be provided with multiple positioning posts to position the first fixing member 13. The mounting surface 105 can be fixedly installed by embedding the first fixing member 13 with screws.

[0040] Please see Figure 1 , Figure 2 and Figure 3The first component mounting position 110 is also provided with a PCS positioning mechanism 116, which is spaced apart from the fence mounting platform 114 in the Z direction. The PCS positioning mechanism 116 includes an X-direction limiting part 1162, an X-direction positioning part, a third Y-direction positioning boss 1164, a Z-direction mounting boss 1166, and a Z-direction fixing part. The Z-direction mounting boss 1166 is spaced apart from the first compound eye lens and is located on its Z-direction extension line away from the second compound eye lens, so as to form an air channel between the PCS and the first compound eye lens, thereby facilitating heat dissipation of the PCS and the first compound eye lens. The Z-direction is perpendicular to the X and Y directions. The Z-direction fixing part is provided on the edge of the bracket 100 along the X direction to fix the PCS in the Z direction. The X-direction limiting part 1162 and the first X-direction positioning boss 1121 are spaced apart in the X direction, and the X-direction positioning part is provided on the edge of the bracket 100 along the Y direction to cooperate with the X-direction limiting part 1162 to limit the PCS in the X direction. The third Y-direction positioning boss 1164 and the first Y-direction positioning boss 1123 are spaced apart in the Y direction and are used to limit the PCS in the Y direction. There are four third Y-direction positioning bosses 1164, which are located on opposite sides of the bracket 100.

[0041] Please see Figure 1 , Figure 2 and Figure 4 The first component mounting position 110 is also provided with a fence mounting platform 114, which protrudes from the inner wall 101 of the bracket 100. In this embodiment, the fence mounting platform 114 includes four parts that are connected end to end and form four corners.

[0042] The fence mounting platform 114 is provided with a first Z-direction support platform 1141 and fence positioning posts 1143. The first Z-direction support platform 1141 protrudes from the fence mounting platform 114 along the Z-direction. Multiple first Z-direction support platforms 1141 can be provided, and they are used to support and place the fence 40. The fence positioning posts 1143 protrude from the fence mounting platform 114 along the Z-direction and are spaced apart from the first Z-direction support platforms 1141. The fence positioning posts 1143 are used to position the fence 40. In this embodiment, there are two fence positioning posts 1143, located at two opposite corners of the fence mounting platform 114.

[0043] In one embodiment, the number of fence positioning posts 1143 can be one, three, four, or more. In another embodiment, two fence positioning posts 1143 can be located in adjacent positions.

[0044] Please see Figure 2 and Figure 5The X-direction positioning part includes a first fixing member 13, which includes a fixing piece 132 and a first spring piece 134 and a second spring piece 136 connected to the fixing piece 132. The fixing piece 132 is generally a rectangular sheet structure and is mounted on the edge of the bracket 100 along the Y-direction, specifically on the mounting surface 105. In this embodiment, the fixing piece 132 is mounted by passing a screw through it to the mounting surface 105. In other embodiments, the fixing piece 132 can also be fixedly connected to the mounting surface 105 by bonding, welding, fasteners 19 such as screws, or other methods. The first spring piece 134 abuts against the first compound eye lens in the opposite direction of the Z-direction to fix the first compound eye lens in the Z-direction. The second spring piece 136 abuts against the PCS in the opposite direction of the X-direction to cooperate with the X-direction limiting part to fix the PCS in the X-direction. There are two second spring pieces 136, which together position the PCS in the X-direction. In other words, the first fixing member 13 can simultaneously position the PCS in the X direction and the first compound eye lens in the Z direction, which can reduce the use of fixing members and make the installation structure 10 simpler.

[0045] Please continue reading. Figure 2 The Z-direction fixing part includes a second fixing member 15, which is installed on the edge of the bracket 100 along the X-direction to fix the PCS along the Z-direction. In this embodiment, there are two second fixing members 15, which are located on both sides of the bracket 100 to fix the PCS in the Z-direction. The second fixing member 15 is set separately from the first fixing member 13 to avoid mutual interference between the first fixing member 13 and the second fixing member 15. For example, when the pressure foot of one fixing member is tightened, it may cause the pressure foot of the other fixing member to lift up, resulting in insufficient tightening force. The second fixing member 15 is installed on the top wall 103. The second fixing member 15 is also generally a rectangular sheet structure, and the second fixing member 15 may also include multiple spring pieces, which are bent along the Z-direction.

[0046] Please see Figure 2 and Figure 6 The second positioning mechanism 121 is also provided with a third Z-direction support platform 1216, which is spaced apart from the second X-direction positioning boss 1212 and the second Y-direction positioning boss 1214.

[0047] The mounting structure 10 also includes a third fixing member 17, which is adjacent to the second positioning mechanism 121 and mounted on the bracket 100. The third fixing member 17 includes a mounting piece 172, a third spring piece 174 connected to the mounting piece 172, and a positioning piece 176 bent relative to the mounting piece 172. The positioning piece 176 engages with the buckle 1021. The third spring piece 174 is bent relative to the mounting piece 172 in the Z direction to provide a restoring force in the Z direction.

[0048] The mounting structure 10 also includes a fourth fixing member 18, which has the same structure as the second fixing member 15. The fourth fixing member 18 and the first fixing member 13 are located on opposite sides of the bracket 100. The fourth fixing member 18 is installed on the edge line of the bracket 100 along the Y direction and is used to position the first compound eye lens 20 along the Z direction.

[0049] In this embodiment, the number of the first fixing member 13, the third fixing member 17 and the fourth fixing member 18 is one, and the number of the second fixing member 15 can be two, wherein the two first fixing members 13 are positioned opposite each other.

[0050] The mounting structure 10 also includes a fastener 19, which can be used to mount the bracket 100 to the housing of the projection device to secure the bracket 100.

[0051] In summary, the first X-direction positioning boss 1121 and the second X-direction positioning boss 1212, and the first Y-direction positioning boss 1123 and the second Y-direction positioning boss 1214 of the mounting structure 10 for optical components provided by the present invention have the same position and size, small processing error, and improve the positioning accuracy of the first compound eye lens 20 and the second compound eye lens 30. As an example, the positioning accuracy can be improved from 0.05mm to 0.02mm.

[0052] Please see Figure 1 and Figure 7 The present invention also provides an optical component 1, including a first compound eye lens 20, a second compound eye lens 30, and a mounting structure 10 for the optical component according to any of the above embodiments. The first compound eye lens 20 is disposed at a first positioning mechanism 112, and a first X-direction positioning boss 1121 and a first Y-direction positioning boss 1123 cooperate to position the first compound eye lens 20. The second compound eye lens 30 is disposed at a second positioning mechanism 121, and a second X-direction positioning boss 1212 and a second Y-direction positioning boss 1214 cooperate to position the second compound eye lens 30. The optical component 1 of this embodiment can be used for polarization conversion, converting randomly polarized light into linearly polarized light. The optical component 1 can be used in a liquid crystal display projector.

[0053] Please see Figure 4 , Figure 8 and Figure 9 The optical component 1 also includes a grid 40, which is generally a square plate-like structure. The grid 40 is made of aluminum alloy, specifically AL7075, a material that provides high strength and resistance to deformation. The grid 40 is mounted on the grid mounting platform 114 and positioned between the first compound eye lens 20 and the second compound eye lens 30. The grid 40 can be used to separate the incident light beam into multiple beams exiting at different angles.

[0054] The fence 40 is provided with positioning holes 42, protrusions 44, and bosses 46. Fence positioning posts 1143 are embedded in the positioning holes 42 to position the fence 40. Protrusions 44 are located on the surface of the fence 40 near the fence mounting platform 114 and abut against the first Z-direction support platform 1141. In this embodiment, there are four protrusions 44, with two protrusions 44 distributed at each opposite end of the fence 40. As an example, the protrusion height of the protrusions 44 can be 0.2-0.4 mm. The shape of the protrusions 44 is approximately a cuboid structure. Bosses 46 are located on the surface of the fence 40 opposite to the protrusions 44. Bosses 46 are located on the surface of the fence 40 away from the second compound eye lens 30, and abut against the first compound eye lens 20 to form a gap between themselves and the first compound eye lens 20 mounted on the fence 40, thereby facilitating heat dissipation for both the fence 40 and the first compound eye lens 20. In this embodiment, the number, shape, and size of the bosses 46 are the same as the number, shape, and size of the protrusions 44, and the setting position of the bosses 46 corresponds to the setting position of the protrusions 44. This setting facilitates the processing of the protrusions 44 and the bosses 46.

[0055] In other embodiments, the number of protrusions 44 may differ from the number of bosses 46. For example, there may be four protrusions 44 and two or three bosses 46. The shape of the protrusions 44 may also differ from the shape of the bosses 46; for example, the bosses 46 may be roughly cylindrical or triangular prisms. The dimensions of the protrusions 44 may also differ from the dimensions of the bosses 46. As an example, the height of the protrusions 44 may be 0.3 mm, and the height of the bosses 46 may be 0.4 mm. The number and shape of the protrusions 44 and bosses 46 can be set according to actual conditions.

[0056] Please see Figure 7 , Figure 10 and Figure 11The first compound eye lens 20 is also roughly square plate-shaped. It can be used to homogenize multiple beams emitted from the fence 40. The first spring plate 134 presses against the first compound eye lens 20 in the opposite direction of the Z-direction to position it in the Z-direction. This pressing refers to the first spring plate 134 pressing the first compound eye lens 20 against the fence 40. The first spring plate 134 has a restoring force in the Z-direction to achieve the positioning of the first compound eye lens 20 and the fence 40 in the Z-direction.

[0057] The first compound eye lens 20 includes a first side surface 21, a second side surface 22, a third side surface 23, a fourth side surface 24, a first lens surface 25, and a second lens surface 26. The first side surface 21 and the third side surface 23 are opposite to each other, and the second side surface 22 and the fourth side surface 24 are opposite to each other. The first side surface 21 abuts against a first Y-direction positioning boss 1123, and the second side surface 22 abuts against a first X-direction positioning boss 1121. The first lens surface 25 and the second lens surface 26 are opposite to each other, and the first lens surface 25 abuts against the boss 46. In this embodiment, the first lens surface 25 can be the incident surface of light, and the second lens surface 26 can be the exit surface of light.

[0058] The second compound eye lens 30 is abutted against the third Z-direction support platform 1216. The third spring piece 174 presses against the second compound eye lens 30 along the Z-direction to achieve the positioning of the second compound eye lens 30 in the Z-direction.

[0059] Both the first positioning mechanism 112 and the second positioning mechanism 121 include a soft pad 14, which is approximately "L"-shaped. The soft pad 14 is wrapped around the corners of the first compound eye lens 20 or the second compound eye lens 30 to achieve positioning of the first compound eye lens 20 or the second compound eye lens 30 in the X and Y directions. In this embodiment, the soft pad 14 is located between the fourth side surface 24 and the inner wall 101, and also between the second lens surface 26 and the inner wall 101. The soft pad 14 can be made of a plastic material with a certain degree of elasticity to achieve better positioning. In this embodiment, there are two soft pads 14.

[0060] In one embodiment, the number of soft pads 14 can be two, three or four, and the soft pads 14 can be located at the corners of the bracket 100 to satisfy the positioning of the first compound eye lens 20.

[0061] In another embodiment, the pad 14 can also be strip-shaped and not located at the corners, which can also achieve the positioning of the first compound eye lens 20 and the second compound eye lens 30 in the X and Y directions.

[0062] Please see Figure 2 , Figure 3 and Figures 11 to 13The optical component 1 also includes a PCS60. In this embodiment, the PCS60 is also generally a square plate structure, and it is located on the PCS positioning mechanism 116 in the mounting structure 10. The PCS60 is mainly used to convert the polarized light of the first compound eye lens 20 into another polarized light state after homogenization, so as to better utilize the LCD panel. The PCS60 abuts against the X-direction limiting part 1162 and is held by the second spring piece 136 of the first fixing member 13 in the opposite direction of the X-direction, thus fixing the PCS60 in the X-direction. The PCS60 abuts against the third Y-direction positioning boss 1164, thus fixing the PCS60 in the Y-direction. The PCS60 abuts against the Z-direction mounting boss 1166 and is pressed by the second fixing member 15 in the Z-direction, thus fixing the PCS60 in the Z-direction.

[0063] Please see Figure 3 , Figure 14 and Figure 15 Since PCS60 abuts against the Z-direction mounting boss 1166, PCS60 and the first compound eye lens 20 are spaced apart in the Z-direction, thus forming an air duct P1 between the first compound eye lens 20 and PCS60. The air duct P1 consists of three parts: the first part is between the side of PCS60 near the second spring 136 and the inner wall 101; the second part is between PCS60 and the first compound eye lens 20; and the third part is between the side of PCS60 away from the second spring 136 and the inner wall 101. The air duct P1 facilitates heat dissipation for PCS60 and the first compound eye lens 20, preventing PCS60 and the first compound eye lens 20 from having a reduced service life due to overheating.
