[0002] In the prior art, in order to maintain a clean light propagation environment, the optical path formed by the far-infrared imaging device needs to create a sealed environment, so that the optical device is sealingly connected with the opening of the shell, thereby blocking dust. A common way is to fix the optical device to the opening by using foam with glue, which can effectively seal and fix the optical device while also providing buffering and protection. However, under this sealing mode, the difficulty of disassembling the optical device for maintenance or repair is greatly increased, and the operation is inconvenient. In addition, the foam is prone to falling under environmental intervention, including changes in temperature and humidity, and collisions during transportation. SUMMARY

[0015] Preferably, the rubber ring is an irregularly shaped rubber ring.

[0016] Preferably, a second opening is provided on the lower side wall of the housing, and a first opening is provided on the front side wall of the housing; the distant image imaging device further includes a light source, which is disposed opposite to the second opening, and the light emitted by the light source enters through the second opening; a beam splitter, which is adapted to the first opening and disposed opposite to the light source, and the light emitted by the light source is incident on the beam splitter and reflected on the beam splitter; the light reflected by the beam splitter is incident on a curved reflector, and after reflection, it is emitted towards the beam splitter, transmitted through the beam splitter and directed to the exit pupil to form an upright magnified image with a first focal plane depth greater than 1m.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connected" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0033] To facilitate understanding of the embodiments of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this application.

[0034] This embodiment provides a distance imaging device, such as... Figures 1-5 As shown.

[0035] The remote imaging device includes a housing 1, a light source 2, a beam splitter 3, and a curved reflector 4.

[0036] The housing 1 includes a front sidewall, a rear sidewall, a left sidewall, a right sidewall, an upper sidewall, a lower sidewall, and a first sidewall.

[0037] like Figure 3As shown, the lower sidewall of the housing 1 is located below the housing 1, and a second opening 6 is provided thereon. The second opening 6 is arranged opposite to the light source 2, and the light emitted by the light source 2 enters the interior of the housing 1.

[0038] The front sidewall is located in front of the housing 1, and a first opening 5 is provided on the front sidewall. The first opening 5 is adapted to the beam splitter 3 so that the beam splitter 3 is positioned at the first opening 5. The beam splitter 3 is positioned opposite to the light source 2. The light emitted by the light source 2 is incident on the beam splitter 3 and reflected on the beam splitter 3.

[0039] A viewer can observe the image formed inside the housing 1 through the beam splitter 3. The plane of the beam splitter 3 is parallel to the plane of the first opening 5, so that the beam splitter 3 is positioned opposite the light source 2, and the light emitted by the light source 2 will be incident on the beam splitter 3. An adhesive connecting strip is provided around the first opening 5, and the inner side of the beam splitter 3 is connected to the connecting strip. The beam splitter 3 can reflect and refract the received light in a certain proportion, that is, part of the light incident on the beam splitter 3 will be reflected and emitted, while another part will be refracted and emitted. The splitting ratio will determine the proportion of reflected and refracted light. The light emitted by the light source 2 is incident on the beam splitter 3 from below. After being transmitted through the beam splitter 3, the light is emitted from above and does not participate in the formation of the image, and is considered invalid light. After being reflected by the beam splitter 3, the light is emitted backward and participates in the formation of the image, and is considered valid light.

[0040] like Figure 4 As shown, the rear sidewall is located behind the housing 1 and has a third opening 7. The third opening 7 is adapted to fit the curved reflector 4 so that the curved reflector 4 is positioned at the third opening 7. The curved reflector 4 has a concave reflective surface, with the concavity facing away from the first opening 5. The curved reflector 4 is positioned opposite to the beam splitter 3. Light reflected by the beam splitter 3 will be incident on the curved reflector 4, and after being reflected by the curved reflector 4, it will exit towards the beam splitter 3. At this time, the light incident on the beam splitter 3 will be transmitted and exited at the exit pupil position, and the viewer can see an upright, magnified virtual image with a first focal plane depth formed by the far-image imaging device. The first focal plane depth is greater than 1m.

[0041] like Figure 5 As shown, the connection structure between the curved reflector 4 and the housing 1 is specifically as follows:

[0042] The outer ring of the curved reflector 4 is provided with a rubber ring 8 to seal the third opening 7.

[0043] The front side of the curved reflector 4 is limited by a stop block disposed within the housing 1. The stop block includes a first stop block 9 disposed at the top of the housing 1 and a second stop block 10 disposed at the bottom of the housing 1. The upper front end of the curved reflector 4 abuts against the first stop block 9, and the lower front end abuts against the second stop block 10, thereby determining the front position of the curved reflector 4. Further, the rear side of the first stop block 9 has a curvature, with a component extending in the left-right direction, and the length of the first stop block 9 extending in the left-right direction is adapted to the curved reflector 4. The rear side of the second stop block 10 also has a curvature, with a component extending in the left-right direction, and the length of the second stop block 10 extending in the left-right direction is adapted to the curved reflector 4. This arrangement provides guidance and limitation in the left-right direction.

[0044] The rear side of the curved reflector 4 is limited and fixed by a stop member 11 provided at the third opening 7. The rear side of the stop member 11 is fixedly provided to the housing 1, and its front side abuts against the rear side of the curved reflector 4 and the rubber ring 8, so as to clamp the curved reflector 4 and the rubber ring 8 between the stop block and the stop member 11.

[0045] The shifting component 11 includes a first part 17 and a second part 18. The first part 17 is plate-shaped, and its plane is parallel to the planes of the left and right side walls. The front side of the first part 17 is curved, forming a backward-bending shape, which adapts to the rear side of the curved reflector 4, so that the shifting component 11 fits snugly against the curved reflector 4. Furthermore, the first part 17 is provided with a second reinforcing rib 13, which extends in the front-rear direction, and a groove is formed between adjacent second reinforcing ribs 13 to provide a certain buffer. The second part 18 is connected to the first part 17, and the plane of the second part 18 is parallel to the plane of the rear side wall. The second part 18 includes a protrusion, which at least partially covers the rear side wall of the housing 1, and the protrusion is fixedly connected to the housing 1. Figure 4 As shown, the protrusion includes a first protrusion 14 protruding from the upper side of the first portion 17, a second protrusion 15 protruding from the lower side of the first portion 17, and a third protrusion 16 protruding from the right or left side of the first portion 17. The first protrusion 14, the second protrusion 15, and the third protrusion 16 are fixedly connected to the housing 1 by bolts. The above arrangement is for guidance and positioning in the vertical direction.

[0046] The above settings are used for guidance and positioning in the vertical and horizontal directions.

[0047] Due to the fixed connection between the stop member 11 and the housing 1, the position of the first part 17 of the stop member 11 is fixed so that it can press tightly against the curved reflector 4 and the irregular rubber ring 8 sleeved on the curved reflector 4, so as to play a sealing and limiting role. In addition, the stop member 11 extends in the vertical direction to provide support strength in the vertical direction, thereby maintaining the overall stability.

[0048] Because the above structure has a simple connection relationship and is detachable, it will facilitate the maintenance, upkeep and cleaning of the image display device, which will help extend its service life and improve the user experience.

[0049] The upper sidewall, left sidewall, and right sidewall are located on the upper, left, and right sides of the housing 1, respectively, and all three sidewalls are connected to the front sidewall. Furthermore, the upper sidewall, left sidewall, and right sidewall are provided with first reinforcing ribs 12 to improve strength. The first reinforcing rib 12 on the upper sidewall extends in the front-rear direction, and the first reinforcing ribs 12 on the left and right sidewalls have portions extending in the vertical direction and portions extending in the horizontal direction.

[0050] The first sidewall is located in front of the housing 1, and its upper part is connected to the front sidewall. Its left and right sides are connected to the left and right sidewalls, respectively. The front sidewall and the first sidewall are set at an obtuse angle.

[0051] The lower sidewall is located below the housing 1, and a second opening 6 is provided on the lower sidewall. The second opening 6 is opposite to the first opening 5, and the upper edge of the second opening 6 is lower than the lower edge of the first opening 5. The lower sidewall is in contact with the first sidewall, the left sidewall, the right sidewall, and the rear sidewall.

[0052] The rear sidewall is located at the rear of the housing 1, and a third opening 7 is provided on the rear sidewall, which is opposite to the first opening 5. The rear sidewall is connected to the upper sidewall, the left sidewall, the right sidewall, and the lower sidewall.

[0053] Furthermore, the optical device forming the optical path for distant image imaging also includes a lens 19, which is positioned opposite to the light source 2. The light emitted from the light source 2 passes through the lens 19 and then enters the beam splitter 3. The lens 19 can effectively correct the field curvature of the optical system.

[0054] Optical systems require high precision; even minute impurities during light propagation can affect the final imaging effect. To maintain a clean light propagation space, a relatively sealed environment is necessary. This is achieved by surrounding the curved reflector 4 with a rubber ring 8, and securing it with a stop block and a stop element 11. Furthermore, the simple connection structure facilitates the maintenance, upkeep, and cleaning of the image display device, extending its lifespan and improving the user experience.

[0055] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
