[0029] In optomechanical projection systems, the projection chip is a high-precision display device, and the performance and reliability of the projection system are highly sensitive to temperature. Specifically, for Digital Light Processing (DLP) system projectors, the Digital Micromirror Device (DMD) has specific temperature requirements for its normal operation. For ultra-high brightness projection devices, due to the large heat load of the DMD, active cooling using a thermoelectric cooler (TEC) is typically employed. When the TEC's cold surface temperature is too low, water vapor in the air condenses on the surrounding structural surfaces, leading to DMD corrosion or short circuits.

[0030] Therefore, in this application embodiment, an optomechanical device and carrier system are provided to solve or partially solve the above-mentioned problems.

[0031] Please see Figures 1-5 The diagram illustrates a structural schematic of an optomechanical device according to an embodiment of this application, the device comprising:

[0032] 1. Housing; 2. Opto-mechanical module; 3. Refrigeration component; 4. Heat transfer plate; 5. Annular adapter; 6. Sealing component.

[0033] The sealing element includes a first sealing element 61 and a second sealing element 62.

[0034] The side wall of the housing 1 has a first through hole 11. The connecting part of the optical engine module 2 is sealed to the side wall of the first through hole 11. The light emission area of ​​the optical engine module 2 corresponds to the first through hole 11. The light beam emitted by the optical engine module 2 passes through the first through hole 11.

[0035] The annular adapter 5 surrounds the optomechanical module 2 and has a first annular surface 51 and a second annular surface 52 arranged opposite to each other. The first annular surface 51 is sealed to the outer wall of the housing 1 through a first sealing member 61, and the second annular surface 52 is sealed to the heat transfer plate 4 through a second sealing member 62. The heat transfer plate 4, the annular adapter 5, the housing 1 and the optomechanical module 2 constitute an optomechanical cavity.

[0036] The cooling component 3 is located inside the optomechanical cavity and is connected to the heat transfer plate 4, and is used to reduce the temperature inside the optomechanical cavity.

[0037] Please see Figure 4 The arrows in the diagram indicate the direction in which water vapor enters the optical engine module 2. When the optical engine module 2 is running under high load, it needs to be cooled. To this end, a cooling component is designed to cool the optical engine module. However, when cooling the optical engine module, water droplets are easily formed on the cold surface of the cooling component, which can cause irreversible damage to the optical engine module.

[0038] Therefore, this application uses a housing, heat transfer plate, annular adapter, and seals to seal the optical engine module, thereby reducing or partially reducing the entry of moisture into the optical engine module. Specifically, the optical engine module 2 is fixed to the housing 1, the connecting part of the optical engine module 2 is sealed to the side wall of the first through hole 11, the annular adapter 5 is arranged around the optical engine module 2, the first annular surface 51 is sealed to the heat transfer plate 4 through the first seal 61, and the second annular surface 52 is sealed to the outer wall of the housing 1 through the second seal 62. Based on the housing 1, the optical engine module 2, the annular adapter 5, and the heat transfer plate 4 forming a sealed optical engine cavity, the entry of moisture into the optical engine cavity can be reduced to a certain extent, further preventing water droplets from forming on the cold surface of the cooling component 3, and improving the service life of the optical engine module 2.

[0039] For example, the optomechanical module 2 can be a DMD module or a red laser module.

[0040] For example, the cooling component 3 is a device that uses the thermoelectric effect for cooling or heating. It can be a thermoelectric module composed of multiple thermoelectric materials, which can generate a temperature difference when current passes through it, thereby achieving the effect of cooling on one side and heating on the other. The heat transfer plate is connected to the heating side of the cooler to transfer the heat generated by the cooling component to the external environment. The cooling side of the cooling component 3 faces the photomechanical module to cool the degradation module.

[0041] For example, the heat transfer plate can be made of metal or ceramic material, and preferably, the heat transfer plate is a copper plate.

[0042] For example, the sealing element can be at least one of a single-layer sealing ring, a double-layer sealing ring, a multi-layer sealing ring, and a silicone sleeve.

[0043] For further details, please refer to Figures 4-5 The optomechanical device further includes a first heat transfer element 7, and the sealing element further includes a third sealing element 63. The first heat transfer element 7 includes a protrusion 71 and a non-protrusion 72 connected to each other.

[0044] Specifically, the protrusion is connected to the cooling component, the non-protrusion has a first surface and a second surface that are disposed opposite to each other, and the non-protrusion also includes a second through hole that penetrates the first surface and the second surface.

[0045] The optical engine module is located on the first surface. The connecting part of the optical engine module is sealed to the side wall of the second through hole. The second surface is sealed to the side wall of the first through hole through a third sealing element. The light emission area of ​​the optical engine module corresponds to the second through hole. The light beam emitted by the optical engine module passes through the second through hole and the first through hole in sequence.

[0046] The protruding part of the first heat transfer element is connected to the cooling element, and the non-protruding part of the first heat transfer element is connected to the optomechanical module. The first heat transfer element is used to transfer the heat of the optomechanical module to the cooling element in order to dissipate heat from the optomechanical module.

[0047] Specifically, the beam emitted by the optomechanical module is emitted sequentially through the second through hole and the first through hole. The housing, the first heat transfer component, the optomechanical module, the annular adapter and the sealing component constitute a sealed optomechanical cavity, which can prevent a large amount of water vapor from condensing and seeping into the critical display area, thus affecting the reliability of the optomechanical system.

[0048] For example, the first heat transfer element may be made of metal or ceramic material.

[0049] For further details, please refer to Figures 4-5 The optomechanical device further includes a second heat transfer element 8, having a third surface 85 and a fourth surface 86 arranged opposite to each other, the third surface 85 facing the optomechanical module 2, and the fourth surface 86 facing away from the optomechanical module 2.

[0050] The protrusion 71 is connected to the third surface 85, and the fourth surface 86 is connected to the cooling component 3.

[0051] The fourth surface 86 of the second heat transfer element 8 is connected to the cooling element 3, and the third surface 85 is connected to the protrusion 71 of the first heat transfer element. The second heat transfer element 8 is used to transfer the heat of the optomechanical module 2 to the cooling element 3.

[0052] For example, the second heat transfer element can be plate-shaped, which can increase the area for heat transfer, so as to quickly cool down the optomechanical module.

[0053] For example, the second heat transfer element may be a metal material or a ceramic material.

[0054] For further details, please refer to Figure 6 It also includes: a first water-absorbing element 81 disposed on the third surface 85, and a side of the second heat transfer element 8 adjacent to the third surface 85.

[0055] For further details, please refer to Figure 6 It also includes: a second absorbent element 82, disposed on the first surface and the second surface.

[0056] Specifically, the first water-absorbing component 81 is provided on the third surface 85 to absorb water vapor inside the optical engine cavity, and the second water-absorbing component 82 is provided on the first and second surfaces to absorb water vapor inside the optical engine cavity, which can prevent water vapor from corroding or damaging the optical engine module 2 to a certain extent.

[0057] For example, the first absorbent and the second absorbent can be at least one of foam and sponge.

[0058] For further details, please refer to Figure 6 The second heat transfer element 8 includes an extension 83 and a non-extension 84 connected to each other. The non-extension 84 is used to connect with the protrusion of the first heat transfer element 7. The extension 83 corresponds to the key display area of ​​the optomechanical module 2. The extension 83 is sealed to the optomechanical module 2 by a sealing ring 66 to achieve the sealing of the key display area, which can further prevent water vapor from entering the key display area of ​​the optomechanical module 2.

[0059] For further details, please refer to Figures 5-6 It also includes: a water absorption assembly, comprising a desiccant and an adsorption cavity 9, wherein the desiccant is located inside the adsorption cavity 9 and the adsorption cavity 9 is connected to the optomechanical cavity.

[0060] It should be noted that the surface area of ​​the first heat transfer element 7 and the second heat transfer element 8 is limited, and the water absorption capacity of the first water absorption element 81 and the second water absorption element 82 on their surfaces is limited. Therefore, a water absorption assembly can be set up, including a desiccant and an adsorption cavity 9. The adsorption cavity 9 is connected to the optomechanical cavity, and the water absorption assembly can adsorb more water vapor in the cavity, ensuring that the optomechanical cavity maintains a dry environment and preventing the optomechanical cavity from being corroded by water vapor.

[0061] Furthermore, the adsorption cavity has a material replacement door and a material replacement port. When there is too much water vapor in the optical engine cavity and the desiccant absorbs too much moisture, the material replacement door can be opened to replace the desiccant, which can continuously maintain the dryness of the optical engine cavity.

[0062] For further details, please refer to Figure 7 It also includes: prism 10, the sealing element further includes a fourth sealing element 64, the prism 10 is sealed to the inner wall of the housing 1 through the fourth sealing element 64, the light receiving area of ​​the prism 10 is correspondingly arranged with the first through hole, and the light beam emitted by the optical engine module 2 passes through the second through hole, the first through hole and the prism 10 in sequence.

[0063] Please see Figure 7The arrows in the diagram indicate the direction in which water vapor enters the optomechanical module 2. Water vapor in the external environment can easily enter the optomechanical device, resulting in excessive water vapor inside the cavity of the optomechanical device, which can easily cause corrosion and damage to the optomechanical module.

[0064] To this end, this application uses a fourth sealing element 64 to seal the prism 10 to the inner wall of the housing 1. The optomechanical module 2 and the emitted light beam pass sequentially through the second through hole, the first through hole, and the prism 10, which can prevent water vapor from entering the optomechanical module 2 from the prism 10. This further prevents water droplets from forming on the cold surface of the cooling element 3, thus improving the service life of the optomechanical module 2.

[0065] Furthermore, it also includes: a cover plate 101, and the seal further includes a fifth seal 65.

[0066] The side wall of the housing 1 has a third through hole, and the cover plate 101 is sealed to the side wall of the third through hole by a fifth sealing member 65.

[0067] Please continue reading. Figure 7 As can be seen, moisture in the external environment can easily enter the optomechanical device through the cover plate. Therefore, this application uses the fifth sealing element 65 to achieve a sealed connection between the cover plate 101 and the housing 1, which can prevent moisture from entering the optomechanical cavity from the cover plate 101.

[0068] This application employs a multi-layered sealing structure from the outside in, using multiple double-layer and single-layer sealing rings to block moisture. Multiple foam pads are used to absorb and reduce condensation accumulation, and silicone sleeves are used to isolate critical areas. This prevents excessive moisture condensation from seeping into the critical display areas of the optomechanical module, thus improving the module's reliability.

[0069] This application also proposes a carrier system comprising: a main body and the aforementioned optomechanical device; the main body having a mounting position for mounting at least one of the optomechanical devices.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
