Description
Technical Field
[0001] The present invention relates to the technical field of optical sights, and in particular to a calibration device for laser optical sights. Background Art
[0002] With the continuous advancement of science and technology, laser optical sights have been widely used in military, hunting, precision measurement and high-end optical research fields. The core function of a laser sight is to provide users with high-precision target locking capabilities through the collaboration of laser beams and optical systems. However, with the diversification of usage requirements and the complexity of environmental conditions, traditional laser optical sights have gradually exposed some problems, such as beam offset, spot diffusion, insufficient brightness, and reduced aiming stability. These problems not only affect the user's operating experience, but may also have an adverse effect on the success rate of the mission. Therefore, in order to solve these problems, a calibration device for laser optical sights came into being;
[0003] There are still the following defects in specific use:
[0004] 1. Beam deviation can lead to inaccurate target positioning, especially in long-range shooting or precision measurement, where small angular deviations can translate into significant positioning errors. Environmental vibrations or thermal expansion and contraction can cause the alignment accuracy of the optical system or mechanical structure to decrease, thereby affecting the stability and focusing performance of the laser beam. Vibration and thermal expansion and contraction can change the relative position of optical components, causing the beam spot position on the target to change.
[0005] 2. When the signal received by the reflector is weak, the detection equipment has difficulty distinguishing the characteristics of the light beam, such as direction and intensity. In an automatic calibration or closed-loop feedback system, a weak signal will make it impossible for the system to accurately adjust the direction or intensity of the light beam. A light beam with insufficient brightness may not form a clear light spot or light spot on the target.

[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] (1) The present invention utilizes the connection plate and the adapter plate to cooperate with each other, and the optical path guiding mechanism can provide a multi-point adjustment function, which helps to correct the directional deviation of the light beam and ensure that the light beam is transmitted along the predetermined path; the optical path guiding mechanism can gradually expand or compress the light beam during the emission process to adjust the light energy density distribution and avoid the problem of too high energy in the center of the light beam and too low energy at the edge; the light path guiding mechanism causes a slight disturbance in the light beam path to avoid the phenomenon of light beam superposition caused by multiple reflections; the light path guiding mechanism can evenly distribute the light beam energy to a larger range, thereby alleviating the problem of local overheating of optical components; the movement of the light path guiding mechanism can disperse the stress points of the mechanical structure and reduce the single-point stress concentration when fixing the optical components; during the light beam emission process, the light path guiding mechanism can adjust the path to avoid directly exposing the high-power area of the light beam and reduce safety risks;
[0023] (2) The present invention utilizes a reflector and a cam to cooperate with each other. Through the light intensity feedback mechanism, it can reflect part of the light beam in real time and monitor its brightness. This detection method enables the system to dynamically adjust the light beam output to avoid the light beam being too weak to affect the working effect; the light intensity feedback mechanism automatically enhances the brightness of the light beam. The reflector can be adjusted according to the feedback signal to ensure that the light beam always maintains sufficient brightness to improve the visibility of the light spot; through the light intensity feedback mechanism, the light beam path can be adjusted without affecting other operations. This flexibility enables the system to make fine adjustments when facing environmental changes (such as temperature, humidity, etc.), thereby maintaining a stable light beam intensity and preventing the light beam from weakening due to environmental changes; through the adjustment and reflection of the reflector, excessive diffusion and loss of the light beam during transmission are avoided.

This mechanism not only improves the brightness, but also improves the utilization efficiency of the light beam; the gap deflection of the reflector can fine-tune the angle of the light beam to ensure that it is correctly focused on the target and improve the aiming accuracy. At the same time, the reflection detection function also provides real-time feedback on deviations, helping to automatically correct the beam direction and ensure that the target is always within the beam range. By combining a certain material with the beam to reflect the detection, the reflectivity can be increased, improving the efficiency of the beam reflected on the reflector. This design optimizes detection and reflection efficiency, reduces energy loss caused by beam attenuation, and further enhances the brightness of the light spot on the target.
[0024] (3) The present invention utilizes a rod-type block and an electric telescopic rod to cooperate with each other, and through the light speed expansion mechanism, it can effectively reduce the risk of the light beam deviating from the predetermined trajectory and ensure the focusing quality of the light beam; by adding the light speed expansion mechanism, it can ensure that the light beam passes through the appropriate optical element, thereby maintaining the high brightness and clarity of the light beam; by adjusting the contact area, the energy distribution of the light beam can be controlled, thereby improving the power density of the light beam; controlling the contact area can ensure that the contact area between the light beam and the transmission medium is appropriate, avoiding excessive energy loss and improving the overall system efficiency; through the light speed expansion mechanism, the brightness distribution of the light beam can be made more uniform, avoiding the phenomenon of uneven light spot and inconsistent brightness, thereby improving the quality and reliability of laser applications; by controlling the contact area that the light beam finally passes through, it can effectively disperse heat, avoid overheating and component damage, and improve the service life of the equipment; BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Summary 2: Compared to existing technologies, which suffer from insufficient beam brightness and weaken the signal reflected by reflector 315, the present invention utilizes a light intensity feedback mechanism 3 to reflect a portion of the beam in real time and monitor its brightness. This detection method enables the system to dynamically adjust beam output, preventing a weak beam from affecting operational performance. The light intensity feedback mechanism 3 automatically enhances beam brightness. Reflector 315 adjusts based on the feedback signal to ensure the beam always maintains sufficient brightness, enhancing the visibility of the light spot. The light intensity feedback mechanism 3 allows the beam path to be adjusted without affecting other operations. This flexibility allows the system to fine-tune the beam in response to environmental changes such as temperature and humidity, maintaining stable beam intensity and preventing beam weakening due to environmental fluctuations. The adjustment and reflection of reflector 315 prevent excessive beam diffusion and loss during transmission. Accurately directing the beam to the reflection location effectively maintains beam focus and intensity, avoiding energy waste. This mechanism not only improves brightness but also enhances beam utilization efficiency. The intermittent deflection of reflector 315 fine-tunes the beam angle to ensure it is correctly focused on the target, improving aiming accuracy. At the same time, the reflection detection function also provides real-time feedback on deviations, helping to automatically correct the beam direction and ensure that the target remains within the beam range. By combining the reflection detection of a certain material with the beam, the reflectivity can be increased, improving the efficiency of the beam reflected by the reflector 315. This design optimizes detection and reflection efficiency, reduces energy loss caused by beam attenuation, and further enhances the brightness of the light spot on the target.

[0054] The complete working principle and steps of the above embodiment are as follows:
[0055] Initial qualification: Figures 1 to 2 As shown, during operation, the optical sight achieves aiming, calibration, and target lock functions through the precise coordination of its internal structures. When the user activates the optical sight body 1, the laser emitter 15 first generates a high-precision laser beam, which is then focused and calibrated by the optical lens assembly 11 to ensure that the beam propagates precisely along the aiming axis. This process, through the principle of lens refraction, adjusts the beam to the required direction and intensity, ensuring that it is stable and focused after emission. The optical window 12 serves as an observation port, providing a clear field of view, allowing the user to intuitively see the target area. The window surface is also anti-reflective and scratch-resistant, ensuring long-term use.
[0056] The user can fine-tune the laser's angle, intensity, and focus using the beam adjustment knob 13. The internal mechanical structure of the beam adjustment knob 13 drives the lens assembly to change the direction or spread of the beam. The design of the beam adjustment knob 13 ensures precise positioning, preventing deviation caused by vibration or manual error.
[0057] In situations where ambient light is strong or external interference is significant, the protective structure 14 acts as a shield, reducing the interference of stray light on the laser. It also protects the delicate components within the laser emitter 15 from external factors such as dust and moisture, extending the life of the device.
[0058] Throughout the aiming process, the beam maintains high linearity and brightness upon exiting the optical sight body 1, ensuring a clear and visible light spot on the target. If the target deviates or requires recalibration, the user can quickly adjust the beam adjustment knob 13 and observe the optical window 12 until optimal aiming is achieved. After the laser is fired, the optical window 12 displays the positioning of the target area, allowing the user to confirm the accuracy of the operation through real-time observation.
[0059] When using:
[0060] The optical path guiding mechanism is used to correct the directional deviation of the light beam and ensure that the light beam is transmitted along the predetermined path. Step 2:
[0061] like Figures 3 and 4As shown, when the laser emitter 15 generates a high-precision laser beam, the operator starts the motor housing 21 inside the protective structure 14, and then the short rod 22 connected to one end of the motor housing 21 rotates. The rotation of the short rod 22 also drives the connecting rod 23 connected to one end to rotate to a point on the horizontal trajectory. In this way, the movement of the connecting rod 23 also pulls the inner rod 24 connected to one end to rotate, so that the center plate 25 fixed to one end of the inner rod 24 will deflect back and forth with the rotation of the inner rod 24, thereby The left and right deflection of the core plate 25 will also pull the adapter plates 26 rotatably connected on both sides thereof to produce left and right reciprocating deflection fluctuations. In this way, the left and right reciprocating deflection fluctuations of the adapter plates 26 will also pull the outer plates 27 rotatably connected on the outside thereof to move horizontally in the slide rails provided inside the obstacle bottom block 29. At the same time, the movement of the connecting plate 28 will also drive the obstacle bottom block 29 fixedly connected at its bottom end to move synchronously. Therefore, through the fluctuating deflection of the center plate 25, the adapter plate 26 and the outer plates 27, the light beam emitted by the laser emitter 15 is distributed in a wave-shaped movement trajectory.
[0062] The light intensity feedback mechanism for real-time reflection of part of the light beam and monitoring its brightness has three steps:
[0063] like Figures 5 and 6 As shown, when the center plate 25 rotates, the cam 31 fixedly connected to the outer wall of one side thereof will rotate, and then the rotation of the cam 31 will press down and push the contact block 34 that its lower end abuts to move downward. At the same time, the rotation of the cam 31 will also drive the wedge wheel 32 connected to the outer wall of one side thereof to rotate. In this way, the rotation of the wedge wheel 32 will cause the convex arc surface set at its lower end to first slide on the concave arc surface of the outer wall of the half shaft disc 33. When the wedge wheel 32 rotates until the cylindrical obstacle column set at its top is engaged with the outer wall of the half shaft disc 33, the cylindrical obstacle column will push the half shaft disc 33 to rotate. Therefore, the rotation of the half shaft disc 33 will drive the disc 314 fixedly connected to its upper end to rotate. In addition, the downward movement of the contact block 34 will drive the connecting rod 35 on the outer wall of one side thereof to move and deflect synchronously, and then the connecting rod 35 The deflection of the crank 36 will also pull the crank 36 connected to one end to rotate, so that the rotation of the crank 36 drives the deflection rod 37 connected to one end to rotate, so that the rotation of the deflection rod 37 will cause the rotating rod 38 connected to one end to rotate, and the double-headed buckle 39 fixedly connected to one end of the rotating rod 38 to deflect synchronously, and then the deflection of the double-headed buckle 39 will pull the swing rod 310 connected to one end to deflect up and down, thereby driving the extrusion block 311 fixedly connected to one end to slide on the outer wall of the fixed column 312, and the up and down movement of the extrusion block 311 will push the reflector 315 that its top end contacts to move up and down on the surface of the disk 314, finally realizing the speed of light reflected to the surface of the laser emitter 15 after divergence through the phosphor covered on the surface 415, which makes it convenient for the operator to judge its lighting effect;
[0064] The light speed expansion mechanism for controlling the energy distribution of the light beam and thus increasing the power density of the light beam has four steps:
[0065] like Figures 7 and 8 As shown, when the obstacle bottom block 29 follows the connecting plate 28 in the movement, the obstacle bottom block 29 moves to trigger the touch switch 43, and then the electric telescopic rod 42 moves to one side and extends, so that the support block 41 fixedly connected to the outer wall of the electric telescopic rod 42 will move and extend synchronously with the electric telescopic rod 42. As a result, the card rod 45 engaged in the square groove opened on the upper surface of the electric telescopic rod 42 will be deflected and pushed as the support block 41 moves. In this way, the deflection of the card rod 45 will drive the double-headed rod 46 connected to one end of the card rod to rotate, and the rotation of the double-headed rod 46 will also drive the deflected rod 47 connected to one end of the card rod to rotate, and then the rod-belt block 48 connected to one end of the deflected rod 47 will be deflected and pulled together, and the long rod 49 connected to the other end of the double-headed rod 46 will synchronously pull the symmetrically installed rod-belt block 48 to move in the opposite direction, thereby ensuring that the contact area between the light beam and the transmission medium is appropriate.
