Description

Technical Field

[0001] The invention relates to the technical field of optoelectronic imaging technology gun sights, and in particular to a high-precision large-angle mounting mechanism. Background Art

[0002] As a common tool for acquiring images, optical imaging systems have been widely used in industrial production, daily civilian use, scientific research, military detection and other fields, especially in the field of military confrontation. Modern medium-sized portable weapons are characterized by long range, light weight and high precision. Improving the shooting accuracy of weapons generally requires optical imaging systems. Excellent weapon systems are generally equipped with optoelectronic fire control to achieve precise strikes on targets.

[0003] Trajectory refers to the trajectory of the center of gravity of the bullet after it is pushed out by the gunpowder gas. Different types of bullets have different trajectories. The trajectory is affected by crosswind, longitudinal wind, bullet type, air pressure and temperature. Therefore, for long-distance targets, the shooting angle should be determined according to the various trajectory curves and trajectory correction parameters. The optoelectronic fire control calculates the shooting angle of the weapon by collecting environmental parameters, bullet type and target distance. The optoelectronic fire control makes full use of the divisions in the field of view to determine the aiming direction. The specific method is: first set the initial division in the optoelectronic fire control as the initial aiming line, which can be adjusted to be parallel to the weapon line, and use the aiming line to aim at the target for distance measurement, while collecting environmental variable parameters (wind speed, air pressure, temperature, bullet type, etc.), and then solve it to calculate the position relationship of the shooting aiming line relative to the weapon line, and form an aiming division. By aiming at the target through the division, a precise strike can be achieved.

[0004] Generally, the field of view, weight, and effective distance of optoelectronic products restrict each other. Products with long effective distance and light weight generally have a small field of view. Optoelectronic products will balance technical parameters such as effective distance, weight, and field of view in the early design stage. However, for weapon systems equipped with a large shooting angle, there must be enough field of view to meet the full range installation requirements. Therefore, high-resolution, large-array optoelectronic sensors should be given priority in the design of optoelectronic imaging systems. On the other hand, it is necessary to increase the focal length of the product as much as possible while taking into account the weight of portable products and other requirements. From a design perspective, this is very difficult, so it is necessary to complete the installation of the large-angle weapon system through a combined field of view.

[0005] There are usually two ways to achieve a combined field of view: one is to use multiple optical systems in parallel. This method has a stable optical axis, but the volume is increased and the cost is high. The second is to use an external mechanical shift mechanism to expand the field of view of the table. In this method, the switching between different gears requires that the horizontal direction cannot deviate. At the same time, the positioning of each gear needs to be accurate and reliable to ensure the correctness of the trajectory solution table.

[0006] In the external optoelectronic fire control, the stability and accuracy of the shift mechanism are the basic elements to ensure the accuracy of the optoelectronic fire control meter. The present invention proposes a high-precision external meter mechanism, which achieves the accuracy of meter installation at different gears through mechanical switching of manual external meter installation, automatic gear judgment, automatic gear accuracy correction and other measures. The main problems to be solved by the present invention are: 1. Self-positioning; 2. Elimination of errors in the intervals of different positioning holes due to machining tolerances and adjustment factors; 3. Automatic judgment of the position after shifting to ensure the correctness of the solution; 4. Elimination of the horizontal offset error caused by shifting high and low positioning holes; 5. Stability of the shift mechanism after impact, vibration and shooting. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention discloses a high-precision large-angle meter installation mechanism, which achieves the accuracy of meter installation at different gears through mechanical switching of manual external meter installation, automatic gear position judgment, automatic gear position accuracy correction and other measures.

[0008] The present invention is achieved through the following technical solutions:

[0009] A high-precision large-angle meter mounting mechanism, comprising:

[0010] Sight: The sight is an independent optoelectronic fire control sight, which integrates a white light objective lens, an optoelectronic fire control module, an external environment parameter acquisition module, an angle sensor and a Hall sensor;

[0016] Fire control system: The fire control system is used to receive various sensor signals and calculate the aiming line position to achieve accurate installation.

[0017] Preferably, the optoelectronic fire control module collects the angle height and azimuth changes when the gear is shifted, calculates the angle deviation and horizontal deviation of the gear, uses them as the initial deviation of the trajectory solution, substitutes them into the trajectory solution equation, and thus accurately calculates the ballistic loading of different gears.

[0018] Preferably, the external environment parameter acquisition module includes a temperature sensor and an air pressure sensor.

[0019] Preferably, the connecting seat also includes a gear positioning hole, a shaft mounting hole and a magnet for a Hall sensor. The gear positioning hole adopts a tapered hole automatic positioning design, and a waist groove is designed between the two holes along the shaft direction.

[0021] Preferably, the locking mechanism further comprises a conical block matched with the gear positioning hole, and is designed with a spring anti-loosening mechanism.

[0024] 2) By automatically detecting the gear position, the operation is simple, there is no problem of operating errors, and the reliability is high.

[0025] 3) By automatically detecting the changes in the azimuth and elevation of the angle sensor, the positioning error can be automatically corrected, reducing errors caused by human operation, and the product has a high degree of intelligence.

[0026] 4) The connection structure adopts a bridge-type stabilizing mechanism with reinforcing ribs. The product can withstand strength tests such as impact, vibration, and shooting, and has high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
