Description

Technical Field

[0001] This invention relates to the field of night vision technology, specifically to a night vision device that integrates laser ranging and infrared illumination. Background Technology

[0002] The night vision device integrating laser ranging and infrared illumination is a high-performance night vision equipment that combines active observation and passive detection technologies. Based on traditional low-light or thermal imaging night vision, it adds the ability to actively emit invisible infrared light for illumination and integrates a laser ranging module, achieving comprehensive performance of "seeing clearly, seeing far, and measuring accurately" in pitch-black environments.

[0003] Due to objective reasons such as optical design, functional modules and structural layout, the front-end lens assembly is more complex. The lens end integrates the objective lens group (multiple lenses) and infrared illuminator. In devices that integrate laser rangefinders, the laser emission / reception module is usually also integrated at the front end. Therefore, the lens end of most monocular night vision devices is heavier than the tail end.

[0004] Excessive weight at the front end can cause the lens of a night vision device to hit the ground first in a fall, resulting in the most vulnerable and delicate lens bearing the full force of the damage. This is mainly due to two core factors: 1. The "hammering effect" caused by the concentrated weight means that all the impact force is concentrated at the edge of the lens, which can easily lead to lens breakage and lens barrel deformation. Furthermore, the repeated bouncing of the equipment after it falls to the ground will cause the cracks caused by the initial impact to expand rapidly, and the damage will spread from the local area to the overall optical structure, greatly increasing the risk of complete scrapping.

[0005] 2. Due to its forward center of gravity, upon impact, the lens will not only be directly damaged, but the impact force will also be transmitted deep into the interior, causing fatal internal damage such as optical axis misalignment, damage to electronic components, or even breakage at the lens-body connection. The repeated impacts after bouncing will also transmit destructive torque to the entire system, causing deep damage that is difficult to repair, thus increasing the risk of damage and repair costs in the event of an accidental fall.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing night vision devices that integrate laser ranging and infrared illumination. Summary of the Invention

[0007] The technical solution of this invention addresses the problem of overly simplistic solutions in existing technologies by providing a solution that is significantly different from existing technologies. Specifically, the purpose of this invention is to provide a night vision device that integrates laser ranging and infrared illumination to solve the problems mentioned in the background technology (where excessive weight at the front end of the night vision device causes the lens to hit the ground first upon falling, triggering a "hammering effect" that directly causes lens breakage and barrel deformation; on the other hand, the forward center of gravity transmits the impact to the interior, causing deep damage; and repeated bouncing during falls further amplifies the damage, significantly increasing the risk of complete failure and maintenance costs).

[0008] To achieve the above objectives, the present invention provides the following technical solution: a night vision device integrating laser ranging and infrared illumination, comprising a main body and a circular outer shell fixedly sleeved on the surface of the main body, and further comprising: The device consists of steel balls that sense gravity and roll adaptively on the inner wall of a circular outer shell. A limiting plate symmetrically hinged to the inner wall of a circular outer shell, which senses the falling situation, limits the steel ball, and rotates under pressure. The movable push plate is displaced by the rolling thrust of steel balls on the inner wall of the circular outer shell. Pushing columns and irregularly shaped columns fixed to the back of the push plate and displaced by its push; An active sphere is positioned between the push column and the irregularly shaped column to increase thrust. The movable plate, which is set on one side of the irregular column, shifts with its thrust; A gas storage tank fixed to one side of the main body for temporary gas storage; An airbag is installed on the surface of the main body to receive gas and inflate for cushioning and protection.

[0009] Preferably, a protective shell is symmetrically fixed to the surface of the circular outer shell, and the surface of the protective shell is chamfered; A torsion spring is fixed to the inner wall of the protective shell, and the other side of the torsion spring is fixedly connected to the limiting plate.

[0010] Preferably, the inner wall of the circular outer shell is adapted to the surface of the main body, and the limiting plate and the push plate are both annular; A square outer shell is fixed to one side of the circular outer shell, and a gas storage tank is fixed to the other side of the square outer shell. The gas storage tank is fixed to the bottom of the main body.

[0011] Preferably, a limiting cylinder is fixed to the inner wall of the circular outer shell, and one end of the limiting cylinder extends into the square outer shell; The surface of the limiting cylinder is movably fitted with a pushing column, an irregularly shaped column, and a moving plate.

[0012] Preferably, the surface of the airbag is provided with an elastic band; A connecting pipe connects the airbag and the air tank, and an air inlet pipe is provided at the other end of the air tank; The surface of the connecting pipe and the air inlet pipe are respectively provided with one-way valves, and the other end of the airbag surface is connected to a pressure valve. The main body has a counterweight inside near the airbag.

[0013] Preferably, a push post is movably provided in the square outer shell, and one end of the push post extends movably into the circular outer shell; One side of the push column is symmetrically provided with spheres, and the diameter of the push column on this side is smaller than the distance between the spheres.

[0014] Preferably, the steel ball is in contact with the surfaces of the limiting plate and the push plate, respectively, and the limiting plate is in contact with the surface of the steel ball; The distance between the limiting plate and the inner wall of the circular outer shell is less than the diameter of the steel ball, and the diameter of the limiting plate is less than the diameter of the push plate. The push plate is suspended inside the circular shell, and the distance from the push plate to the upper and lower ends of the inner wall of the circular shell is less than the diameter of the steel ball.

[0015] Preferably, one side of the limiting plate movably penetrates through the circular outer shell and extends into the protective outer shell; The limiting plate is movably connected to both the circular outer shell and the protective outer shell, and has a matching groove.

[0016] Preferably, a conical groove is provided on one side of the push column, and one side of the irregular column is conical, with the conical end of the irregular column inserted into the conical groove of the push column; The surfaces of the pushing column and the irregular column are simultaneously provided with rolling spheres.

[0017] Preferably, a return spring is provided between the push column and the moving plate, and a non-contact limiting cylinder is movably inserted in the middle of the return spring; The movable plate is movably connected to the square outer shell and the gas storage tank, respectively.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a tail counterweight, a steel ball that senses the force of the fall, and a limiting plate to work together to automatically adjust the falling posture of the main body during a fall. This ensures that the more robust and impact-resistant tail end faces downwards first, fundamentally shifting the primary point of impact. The fatal initial impact is guided from the vulnerable lens end to the more resistant tail end, directly avoiding the most likely direct damage such as lens breakage and lens barrel deformation caused by the "hammering effect." At the same time, the steel ball can actively sense gravity and roll adaptively according to the falling posture. After the steel ball rolls, it pushes the gas to deploy the airbag, resulting in a rapid response. Moreover, it remains stable and reliable even in harsh environments (humidity, electromagnetic interference), ensuring the certainty and immediacy of protection.

[0019] 2. This invention uses an airbag and a pressure valve to form a two-stage buffer energy absorption design. The airbag inflates and expands rapidly at the end of the fall, and deflates upon impact to achieve a "soft landing." This effectively avoids the "hard bounce" of the equipment and the resulting repeated bouncing and tipping, completely eliminating the problem of damage spread caused by multiple complex impacts, preventing deep damage to the lens and the inside of the equipment, and providing comprehensive protection for the tail end and lens end, significantly reducing the risk of damage and maintenance costs after an accidental fall.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1 to 14 The present invention provides a technical solution: a night vision device integrating laser ranging and infrared illumination, comprising a main body 1 and a circular outer shell 2 fixedly sleeved on the surface of the main body 1, and further comprising: The activity involves a steel ball 7 that rolls adaptively based on gravity, located on the inner wall of a circular outer shell 2. A limiting plate 8 is symmetrically hinged to the inner wall of the circular outer shell 2 to sense the falling situation and limit the steel ball 7 and rotate under the push; The movable push plate 9 is displaced by the rolling thrust of the steel ball 7 on the inner wall of the circular outer shell 2; The push column 10 and the irregular column 11 are fixed to the back of the push plate 9 and are displaced by the push plate 9; An active sphere 16 is positioned between the push column 10 and the irregular column 11 to increase thrust; A movable plate 12 is set on one side of the irregular column 11 and moves with its thrust; A gas storage tank 5 is fixed to one side of the main body 1 for temporary gas storage; An airbag 3 is installed on the surface of the main body 1 to receive gas and inflate for cushioning and protection.

[0037] Additionally, it should be noted that the main body 1 is primarily composed of a lens, an image intensifier, a miniature display screen, a laser rangefinder, and infrared LEDs. In the dark, it uses its own emitted infrared light to "illuminate" the target. After the light is captured by the lens, it is significantly brightened by the image intensifier and converted into an electronic image, which is then displayed on the miniature screen for human viewing. Simultaneously, it emits a laser beam that hits the target and reflects back. The target distance is measured and displayed in real time by calculating the time difference. This is existing technology and will not be elaborated upon further here.

[0038] In specific implementation, a protective shell 6 is symmetrically fixed to the surface of the circular shell 2, and the surface of the protective shell 6 is chamfered; A torsion spring 13 is fixed to the inner wall of the protective shell 6, and the other side of the torsion spring 13 is fixedly connected to the limiting plate 8.

[0039] Additionally, it should be noted that, utilizing the elasticity of the torsion spring 13, when the main body 1 tilts and falls, the steel ball 7 will simultaneously tilt and roll downwards within the circular outer shell 2 due to gravity. Through gravity and its own weight, it will push the limiting plate 8 to rotate. The torsion spring 13 provides controllable torque for the limiting plate 8 during rotation. After the steel ball 7 rolls past the limiting plate 8, the torsion spring 13 retracts to help the limiting plate 8 reset. The torsion spring 13 allows the limiting plate 8 to automatically reset, enabling subsequent cycles to sense the falling situation.

[0040] In specific implementation, the inner wall of the circular outer shell 2 is adapted to the surface of the main body 1, and the limiting plate 8 and the push plate 9 are respectively annular; a square outer shell 4 is fixed on one side of the circular outer shell 2, and a gas storage tank 5 is fixed on the other side of the square outer shell 4, with the gas storage tank 5 fixed at the bottom of the main body 1.

[0041] Additionally, it should be noted that the inner wall of the circular outer shell 2, as well as the ring-shaped design of the limiting plate 8 and the push plate 9, means that when the main body 1 moves during use, the steel ball 7 rolls in the circular outer shell 2 and eventually stops at the lowest point. However, the rolling force cannot push the limiting plate 8 to rotate, so the steel ball 7 will not pass through the limiting plate 8.

[0042] When the main body 1 lands in a random posture, any one of its outer surfaces may face upwards. The steel ball 7 will automatically roll within the circular outer shell 2 under the influence of gravity. As the main body 1 falls, the steel ball 7 is simultaneously rolled to the lowest point of the circular outer shell 2 under the influence of gravity. Thus, the steel ball 7 can sense the falling situation regardless of the falling posture of the main body 1, providing comprehensive sensing without blind spots. At the same time, the width and position of the limiting plate 8 and the push plate 9 are adapted to the diameter of the steel ball 7. When the steel ball 7 rolls, it determines whether it rolls past the limiting plate 8 based on the magnitude of gravity and the degree of tilt of the main body 1. Without relying on batteries or electronic sensors, the steel ball 7 reacts simultaneously with the situation of the main body 1, enabling immediate protection.

[0043] In a specific implementation, a limiting cylinder 15 is fixed to the inner wall of the circular outer shell 2, and one end of the limiting cylinder 15 extends into the square outer shell 4; a pushing column 10, an irregular column 11 and a moving plate 12 are movably sleeved on the surface of the limiting cylinder 15.

[0044] Additionally, it should be noted that the limiting cylinder 15 restricts the direction of movement of the pushing column 10 and the irregular column 11. When the push plate 9 is pushed by the steel ball 7, it simultaneously drives the pushing column 10 and the irregular column 11 to move outward in the square outer shell 4, so that the return spring 14 is continuously compressed into a "cylinder" by the force, and then continues to push the moving plate 12 to move on the surface of the limiting cylinder 15. The moving plate 12 is pushed to continuously squeeze the gas in the gas storage tank 5.

[0045] In practice, an elastic band is provided on the surface of the airbag 3; Additionally, it should be noted that the elastic band does not interfere with the expansion of the airbag 3 under force, and helps the airbag 3 to retract and return to its original position after use.

[0046] A connecting pipe connects the airbag 3 and the air tank 5, and an air inlet pipe is provided at the other end of the air tank 5; a one-way valve is provided on the surface of the connecting pipe and the air inlet pipe respectively, and a pressure valve is provided at the other end of the surface of the airbag 3. Additionally, it should be noted that the connecting pipe accurately delivers gas to the airbag 3, preventing it from flowing back into the gas tank 5. After the airbag 3 inflates and falls to the ground, the internal air pressure of the airbag 3 increases, opening the pressure valve and reducing gas leakage. As a result, the gas inside the airbag 3 decreases and deflates, the airbag 3 adheres to the ground, absorbing the impact and becoming difficult to bounce back. At this point, the tail end of the main body 1 lands first, followed by the lens end, which gradually and slowly lands, achieving a smooth and safe stop. After stopping, the gas tank 5 is empty and under negative pressure. The air inlet pipe of the gas tank 5 draws in gas, filling the gas tank 5 with gas for the next use.

[0047] The main body 1 has a counterweight inside near the airbag 3.

[0048] Additionally, it should be noted that the design of the counterweight ensures that the main body 1 falls with its tail end facing down. Even if the lens end is initially facing down, the falling posture is automatically adjusted to keep the lens end on top, preventing the lens end from directly hitting the ground and being damaged by the huge impact. This protects the lens. The tail end has a rubber eyecup and battery compartment, making it much more impact-resistant than a delicate, fragile, and expensive lens. Even if it is damaged, the repair cost and difficulty are greatly reduced.

[0049] In a specific implementation, a push post 10 is movably provided in the square outer shell 4, and one end of the push post 10 extends movably into the circular outer shell 2; A sphere 16 is symmetrically arranged on one side of the push column 10, and the diameter of the push column 10 on this side is smaller than the spacing of the spheres 16.

[0050] In practice, the steel ball 7 is in contact with the surfaces of the limiting plate 8 and the push plate 9 respectively, and the limiting plate 8 is in contact with the surface of the steel ball 7; the distance between the limiting plate 8 and the inner wall of the circular outer shell 2 is less than the diameter of the steel ball 7, and the diameter of the limiting plate 8 is less than the diameter of the push plate 9; the push plate 9 is suspended in the circular outer shell 2, and the distance between the push plate 9 and the upper and lower ends of the inner wall of the circular outer shell 2 is less than the diameter of the steel ball 7.

[0051] Additionally, it should be noted that when the steel ball 7 senses the falling of the main body 1, the steel ball 7 rolls along the downward falling posture of the main body 1, pushing the limiting plate 8 to rotate and tilt in the circular outer shell 2. The rolling of the steel ball 7 and the tilting of the limiting plate 8 simultaneously push the push plate 9 to move. Then the steel ball 7 rolls past the limiting plate 8, and the limiting plate 8 continues to push the push plate 9 to move.

[0052] In practice, one side of the limiting plate 8 moves through the circular outer shell 2 and extends into the protective outer shell 6; The limiting plate 8 is movably connected to both the circular outer shell 2 and the protective outer shell 6, and has a matching groove.

[0053] Additionally, it should be noted that the limiting plate 8 is hinged to the circular outer shell 2, and one end of the hinge between the limiting plate 8 and the circular outer shell 2 passes through the circular outer shell 2, rotating in the groove of the circular outer shell 2 as the limiting plate 8 rotates.

[0054] In specific implementation, a conical groove is provided on one side of the push column 10, and one side of the irregular column 11 is conical. The conical end of the irregular column 11 is inserted into the conical groove of the push column 10. Spheres 16 are rolled on the surfaces of both the push column 10 and the irregular column 11.

[0055] Additionally, it should be noted that the force applied to the push column 10 causes the sphere 16 to move simultaneously. The push column 10 and the sphere 16 together push the irregular column 11 to move. The sphere 16 and the push column 10 push the irregular column 11 along its conical end, increasing the thrust on the irregular column 11.

[0056] In specific implementation, a reset spring 14 is provided between the push column 10 and the moving plate 12, and a non-contact limiting cylinder 15 is movably inserted in the middle of the reset spring 14. Additionally, it should be noted that after the gas tank 5 is filled with gas, the moving plate 12 is pushed to reset. At this time, the moving plate 12 pushes the irregular column 11 and the pushing column 10 to gradually reset. The external force of the reset spring 14 is removed at this time, and the spring force generates a rebound force. The reset force drives the pushing column 10 and the irregular column 11 to reset quickly. Thus, the pushing column 10 pushes the push plate 9 to reset quickly. After the push plate 9 pushes the steel ball 7 to move quickly, the steel ball 7 pushes the limiting plate 8 to rotate in the opposite direction, so that the steel ball 7 resets to the initial position through the limiting plate 8.

[0057] The movable plate 12 is movably connected to the square outer shell 4 and the gas storage tank 5 respectively.

[0058] Working principle: When using this night vision device that integrates laser rangefinding and infrared illumination, first turn on the power switch, then aim it at the target area, put your eye close to the eyepiece, and adjust the sharpness and diopter to make the image in your field of vision clearer.

[0059] When the main body 1 falls to the ground unexpectedly in a random posture, the weight of the tail end of the main body 1 is greater than that of its lens end. The main body 1 will fall at an angle with the tail end facing down. As the main body 1 falls at an angle, the steel ball 7 will automatically roll to the lowest point of the circular shell 2 under the force of gravity. At this time, the steel ball 7 pushes the limiting plate 8 to rotate based on gravity and its own weight. The limiting plate 8 rotates in the circular shell 2, causing the torsion spring 13 to twist and extend. Then, one side of the limiting plate 8 rotates to the surface of the push plate 9. The steel ball 7 and the limiting plate 8 push the push plate 9 to move at the same time. As the steel ball 7 continues to roll, the steel ball 7 rolls past the limiting plate 8, and the limiting plate 8 is no longer pushed by the steel ball 7 and rotates back to reset.

[0060] When steel ball 7 rolls past limit plate 8, as Figure 13 and Figure 14 As shown, the steel ball 7 continues to push the push plate 9 downwards due to the tilting gravity of the main body 1. The push plate 9 pushes the push column 10 in the square shell 4 to move. The push column 10 moves under force, causing the ball 16 to move simultaneously. The push column 10 and the ball 16 push the tapered end of the irregular column 11 to move, increasing the thrust on the irregular column 11. At this time, the push column 10 and the irregular column 11 slide on the surface of the limiting cylinder 15, so that the return spring 14 is always squeezed into a "cylinder" by force. Then, it continues to push the moving plate 12 to move. After the moving plate 12 is pushed, it continuously squeezes the gas in the gas storage tank 5 and transports the gas in the gas storage tank 5 to the airbag 3 through the connecting pipe.

[0061] When the gas in the gas tank 5 is delivered to the airbag 3, the airbag 3 rapidly inflates to a full state. The main body 1 falls with its tail end facing down. After inflating, the diameter of the airbag 3 is larger than that of the tail end of the main body 1. It falls and hits the ground first. After being hit by the ground, the huge impact force will cause the airbag 3 to be violently compressed. The compression causes the internal air pressure of the airbag 3 to rise sharply. The increased internal air pressure of the airbag 3 opens the pressure valve, reducing the gas leakage in the airbag 3. As a result, the gas inside the airbag 3 decreases and it deflates. The airbag 3 adheres to the ground and absorbs the impact, making it difficult to bounce up. At this time, the tail end of the main body 1 hits the ground first, followed by the lens end, which gradually and slowly hits the ground, achieving a smooth and safe stop.

[0062] After stopping, the airbag 3 is retracted and reset via the elastic band. The air tank 5 is empty and under negative pressure. The air inlet pipe of the air tank 5 draws in gas, filling the air tank 5 with gas for the next use. After the air tank 5 is filled with gas, the moving plate 12 is pushed to reset. At this time, the moving plate 12 pushes the irregular column 11 and the pushing column 10 to gradually reset. The external force of the reset spring 14 is removed at this time, and the rebound force is generated. The reset elastic force drives the pushing column 10 and the irregular column 11 to reset quickly. Thus, the pushing column 10 quickly pushes the push plate 9 to reset. After the push plate 9 pushes the steel ball 7 to move quickly, the steel ball 7 pushes the limiting plate 8 to rotate in the opposite direction, allowing the steel ball 7 to reset to the initial position through the limiting plate 8.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
