Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an adjusting mechanism and a laser ranging device. Background Art

[0002] Currently, non-contact sensors such as laser rangefinders and infrared light rangefinders are commonly used in drone bomb launchers to monitor the number of remaining projectiles in the ammunition storage compartment in real time, so as to ensure accurate control of the timing and quantity of projectile launches. Its principle is mainly based on the measurement of the distance between the sensor and the projectile: when there are more projectiles loaded in the ammunition storage compartment, the distance between the nearest projectile in front of the sensor and the sensor is shorter; conversely, when the number of projectiles decreases, the distance between the nearest projectile and the sensor extends.

[0003] To ensure the accuracy of the measurement, the sensing surface of the non-contact sensor must be precisely aligned with its ideal design angle to ensure the reliability and consistency of the measurement data. However, due to factors such as the complex internal structure and limited space of the ammunition storage compartment, it is very likely that the sensor cannot be set in the optimal alignment state after installation. This deviation causes attenuation or interference of the signal received by the sensor, thereby affecting the judgment of the distance to the projectile and resulting in counting errors. Summary of the Utility Model
