Technical Field

[0001] This utility model relates to the field of night vision technology, and in particular to a 3D holographic night vision device. Background Technology

[0002] Traditional optical night vision devices rely on image intensifiers for direct optical imaging, lacking an electronic screen. Images are observed directly through the eyepiece module, resulting in limited functionality, inability to record images, and the need to avoid strong light environments. Existing electronic night vision devices are digital, typically acquiring image information through an objective lens. An image processing module and main control module then display the processed image on a screen for observation. They support image recording and sharing, offer rich functional expansion, and have good adaptability to strong light. However, with technological advancements, people's demands for visual perception are increasing, and traditional two-dimensional images can no longer meet user needs. Utility Model Content

[0005] Furthermore, it also includes a housing assembly, with the camera module and the fill light module both extending from the rear end of the housing assembly, and the light-transmitting display screen protruding from the front end of the housing assembly.

[0006] Furthermore, the front end of the housing assembly is provided with a goggle cover, and the lower part of the goggle cover is provided with a nose-avoiding notch.

[0007] Furthermore, the main control module includes a backlight brightness adjustment circuit, which is electrically connected to the backlight panel.

[0008] Furthermore, the main control module includes a display screen color adjustment circuit, which is electrically connected to the light-transmitting display screen.

[0009] Furthermore, the holographic box is a cuboid.

[0010] Furthermore, the length of the holographic box gradually increases from back to front, forming a tiered platform, the horizontal cross-section of which is a right trapezoid or an isosceles trapezoid.

[0011] Furthermore, the holographic enclosure is also equipped with an internal fill light, which is positioned at the front end of the holographic enclosure and illuminates the backlight panel. The internal fill light is electrically connected to the main control module.

[0012] Furthermore, the front end of the holographic box has a frame, and the internal fill light is obliquely disposed on the frame.

[0013] Furthermore, the light-transmitting display screen is embedded in the frame, and the frame is snap-fitted to the holographic box.

[0014] The beneficial effects of this invention are as follows: the image acquired by the objective lens module is processed by the main control module and then displayed on a transparent display screen. The eyepiece module uses a naked-eye 3D holographic box composed of a backlight panel, a holographic housing, and a transparent display screen.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a 3D holographic night vision device, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0018] Please refer to Figures 1-9 A 3D holographic night vision device, comprising: The eyepiece module 100 includes a backlight panel 110, a holographic box 120, and a light-transmitting display screen 130. The holographic box 120 is open from front to back. The backlight panel 110 closes the rear end of the holographic box 120, and the light-transmitting display screen 130 closes the front end of the holographic box 120. The light generated by the backlight panel 110 is transmitted through the light-transmitting display screen 130. The objective lens module 200 includes a camera module 210 and a supplementary lighting module 220; The main control module 300, backlight panel 110, light-transmitting display screen 130, and objective lens module 200 are all electrically connected to the main control module 300. One state of the light-transmitting display screen 130 is configured to display the shooting content of the objective lens module 200.

[0019] The images acquired by the objective lens module 200 are processed by the main control module 300 and then displayed on the transparent display screen 130. The eyepiece module 100 uses a naked-eye 3D holographic box composed of a backlight panel 110, a holographic enclosure 120, and a transparent display screen 130. The image displayed on the transparent display screen 130 forms a suspended stereoscopic effect, achieving a low-cost naked-eye 3D holographic effect, bringing users a novel experience and satisfying consumers' pursuit of visual effects.

[0020] Please refer to Figure 1 and Figure 2It also includes a housing assembly 400, with the camera module 210 and the supplementary lighting module 220 extending from the rear end of the housing assembly 400, and the light-transmitting display screen 130 protruding from the front end of the housing assembly 400. The housing assembly 400 is typically composed of an upper cover 410 and a lower cover 420, which are connected by snaps or screws. There is a mounting cavity between the upper cover 410 and the lower cover 420, and a rear cover 430 is provided at the rear end of the mounting cavity. The objective lens module 200 extends from the rear cover 430, and the eyepiece module 100 is disposed in the mounting cavity and protrudes from the clearance hole on the goggle cover 500. That is, the goggle cover 500 can be directly formed as the front cover, or a front cover can be provided, and the goggle cover 500 is connected to the front cover.

[0021] Please refer to Figure 1 and Figure 2 The front end of the housing assembly 400 is also provided with a goggle cover 500, and the lower part of the goggle cover 500 is provided with a nose relief notch 510. The goggle cover 500 is generally made of skin-friendly flexible material, such as skin-friendly rubber material or skin-friendly silicone material.

[0022] Please refer to Figure 7 The main control module 300 includes a backlight brightness adjustment circuit, which is electrically connected to the backlight board 110. It provides brightness adjustment functionality to adapt to different environmental requirements. The preferred backlight brightness adjustment circuit uses a DC-DC controller UL1 for boost control and voltage regulation. After the LCD-PWM signal activates the EN terminal of UL1, the chip starts working. UL1 controls the switching state of the LX pin, causing the inductor LL1 to alternately "store energy" (increase current) and "discharge" (decrease current, generating back electromotive force). During discharge, diode DL1 conducts, and energy is transferred to the output terminal through the diode. After filtering by C15 and C16, a smooth 18V voltage is obtained. The output voltage is divided by RL8 and RL10 and fed back to the FB pin of UL1. The chip adjusts the switching duty cycle according to the feedback voltage to ensure the output is stable at 18V. The LCD-PWM signal adjusts the working time of UL1 by changing the duty cycle, thereby changing the output power and realizing the adjustment of backlight brightness.

[0023] Please refer to Figure 8 The main control module 300 includes a display screen color adjustment circuit, which is electrically connected to the translucent display screen 130. Display screen color adjustment allows for more scene settings, such as black and white scenes, romantic pink scenes, etc. Most displays on the market have built-in color adjustment capabilities, such as LCD displays; only a signal is needed, such as a button signal.

[0024] Preferably, the holographic box 120 is a cuboid.

[0025] Alternatively, as another embodiment of this utility model, please refer to Figures 3-6The length of the holographic box 120 gradually increases from back to front, forming a tiered structure. The horizontal cross-section of the tiered structure is a right-angled trapezoid or an isosceles trapezoid. The tiered holographic box 120 makes the levitation effect more obvious and enhances the three-dimensional effect.

[0026] Please refer to Figures 3-5 The holographic enclosure 120 also includes an internal fill light 600, which is positioned at the front of the holographic enclosure 120 and illuminates the backlight panel 110. The internal fill light 600 is electrically connected to the main control module 300. Understandably, the internal fill light 600 is optional, not mandatory, and enhances the brightness of the backlight panel 110.

[0027] Please refer to Figures 3-5 The holographic enclosure 120 has a frame 140 at its front end, with an internal fill light 600 tilted on the frame 140. Typically, the internal fill light 600 is positioned on the upper and lower sides of the frame 140, but it can also be positioned on the left and right sides or all four sides as needed. The tilt angle of the internal fill light 600 is generally adjusted as needed, typically illuminating the center of the backlight panel 110. The internal fill light 600 can be positioned inside the frame 140 or outside the frame 140 with a light-transmitting hole.

[0028] Please refer to Figures 3-6 The translucent display screen 130 is embedded in the frame 140, and the frame 140 is snap-fitted to the holographic cabinet 120. This facilitates the disassembly and maintenance of the translucent display screen 130. The frame 140 has several snap-fit ​​slots 121 and several snap-fit ​​bodies 141, which engage with the snap-fit ​​points 121.

[0029] Understandably, the supplementary lighting module 220 can acquire image data in dark environments by selecting either a low-light lamp or an infrared lamp.

[0030] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] In summary, this utility model provides a 3D holographic night vision device where the image acquired by the objective lens module is processed by the main control module and then displayed on a transparent display screen.
