Abstract

The invention relates to a pitching angle adjusting mechanism of a vehicle-mounted radar. In the mechanism, a radar is fixedly connected to a radar support; a fulcrum A fixing hinge shaft is in running fit with the radar support; a direct-current motor of a driving part is connected with a lead screw through a transmission mechanism, and when the direct-current motor drives the lead screw to rotate, a sliding block can be driven by a nut to move up and down; a composite kinematic pair part comprises a moving pair part and a rotating pair part, and a second guide mechanism in the moving pair part can move up and down along with the sliding block; a linear bearing seat can transversely and horizontally move along the second guide mechanism; the linear bearing seat is connected with the radarsupport through the rotating pair part, and when the radar support rotates around the axis of the rotating pair part, the radar support can do pitching swing around the A fulcrum fixing hinge shaft.By adopting a composite motion mode of the moving pair part and the rotating pair part, the function that the radar does pitching swinging around the Z axis is achieved, the angle adjusting precisionis high, and it can be guaranteed that the radar can stay at an accurate position after the angle is adjusted.

Description

technical field

[0001] The invention belongs to the technical field of optical instruments, and relates to a vehicle-mounted radar pitch angle adjustment mechanism. Background technique

[0002] Usually, the vehicle radar and the photoelectric turntable need to be used together. The photoelectric is at the top, and the radar turntable is at the bottom. When the radar is working, it needs to have a small angle (±15°) pitch swing function, and the radar pitch swing and the 360° azimuth movement of the photoelectric turntable cannot interfere with each other. After the radar swings, the stop position is required to be accurate and the self-locking is reliable. Due to the limited working space of the radar, the existing traditional torque motor direct drive structure to realize the radar swing angle occupies too much volume and cannot meet the application requirements.
