Description

Technical Field

[0001] The utility model relates to the technical field of laser radar nozzles, in particular to an enhanced lifting laser radar nozzle. Background Art

[0002] An elevating nozzle laser radar is a key component of a laser radar system, primarily used to control the direction and range of the laser beam. It typically includes a nozzle that can be moved up and down to adjust the laser beam's elevation angle, enabling precise target detection and ranging.

[0003] This nozzle design is crucial in LiDAR systems because it directly affects the system's detection accuracy and coverage. With technological advancements, the requirements for nozzles are becoming increasingly stringent, including miniaturization to accommodate more complex application scenarios and environmental requirements. The functions of a lifting LiDAR nozzle include, but are not limited to: controlling the pitch angle of the laser beam to achieve vertical detection and ranging; supporting the radar system's precise detection of targets at varying heights; and adjusting and optimizing the LiDAR system's detection range and resolution. Therefore, when designing and manufacturing a lifting LiDAR nozzle, the pressures and shocks that may be encountered in various operating environments must be taken into account to ensure that its strength and reliability meet the system's requirements.

[0004] In the existing lifting lidar nozzle design, the assembly strength of each component is relatively weakened due to the influence of miniaturization. The weakened strength of each nozzle component may lead to an increased risk of component failure when facing an instantaneous pressure of 5 bar. What's more, the connection between the connecting rod and the telescopic rod exceeds the assembly structure strength, and there is a risk of falling off; which in turn leads to a shorter lifespan and requires more frequent maintenance and replacement of parts, thereby increasing maintenance costs and downtime; at the same time, insufficient strength may cause the nozzle to deform or fatigue crack during long-term use, thus affecting its stable working performance.
