[0034] First embodiment:

[0035] Reference Figure 1-5An airborne lidar vibration damping device 100 is disclosed for damping the lidar 101. It includes: a guide block 102, a first slide 103, a guide post 104, a first spring 105, a damping block 106, a first slider 116, and a damping element for adjusting the position of the damping block 106. The first slide 103 is vertically slidably connected to the guide block 102. Specifically, the guide block 102 has a guide hole 102a extending along the axial direction of the guide block 102. The first slide 103 is located within the guide hole 102a and can move axially along the guide hole 102a. The guide post 104 is fixedly connected to the guide block 102. The guide block 102 is fixedly connected to a drone 115.

[0036] The first spring 105 is sleeved on the guide post 104, and its two ends are fixedly connected to the first slide 103 and the guide block 102, respectively. Multiple guide posts 104 are provided, and the guide posts 104 are equidistantly distributed along the circumference of the first slide 103. For better guidance of the first slide 103, a portion of the first slide 103 passes through the guide posts 104, and the guide posts 104 further guide the first slide 103. Multiple first springs 105 are provided corresponding to the guide posts 104.

[0037] The first slider is radially slidably connected to the first slide plate 103. Specifically, the first slide plate 103 has a first groove 103a extending radially along the first slide plate 103, and the first slider 116 moves along the first groove 103a. The damping block 106 is fixedly connected to the first slider 116. When the lidar 101 is mounted on the drone 115 for measurement, the damping block 106 reduces the vibration of the drone 115 on the lidar 101, thereby ensuring that the measurement of the lidar 101 is more accurate.

[0038] The adjusting component is used to adjust the position of the damping block 106. When the damping block 106 wears, its position is adjusted to maintain the friction between the damping block 106 and the guide block 102. The adjusting component includes: a push plate 107, a second spring 108, a bolt 109, a drive block 110, and a transmission block 112. The push plate 107 is located on one side of the first slide plate 103. The two ends of the second spring 108 are fixedly connected to the first slide plate 103 and the push plate 107, respectively.

[0039] The threaded end of bolt 109 passes through push plate 107 and is threadedly connected to first slide plate 103. Specifically, push plate 107 has a clearance hole 107a, through which the threaded end of bolt 109 passes, and a gap is provided between the clearance hole 107a and the threaded end of bolt 109. The nut of bolt 109 abuts against push plate 107 (near the threaded end). Drive block 110 is fixedly connected to push plate 107. Transmission block 112 is fixedly connected to first slider 116. First slide plate 103 has a clearance groove 103b, which allows drive block 110 to move. A support column 114 is fixed to the upper end of push plate 107, and laser radar 101 is fixed to push plate 107 via support column 114.

[0040] The drive block 110 includes a first inclined surface 110a, and the transmission block 112 includes a second inclined surface 112a. The drive block 110 drives the transmission block 112 to move via the first inclined surface 110a and the second inclined surface 112a. A baffle 113 is provided at one end of the guide post 104, which is used to limit the movement of the first slide plate. Under the action of the second spring 108, the first inclined surface 110a of the drive block 110 abuts against the second inclined surface 112a of the transmission block 112. The damping block 106 is made of rubber. When the damping block 106 wears down and the damping effect is reduced, the bolt 109 is turned with an open-end wrench. The bolt 109 will drive the drive block 110 to move, and the first slider 116 will move along the first slide groove 103a. Therefore, the drive block 110 drives the transmission block 112 and the first slider 116 to move along the first slide groove 103a through the first inclined surface 110a and the second inclined surface 112a, thereby adjusting the position of the damping block 106 and ensuring the friction between the damping block 106 and the guide block 102, thereby ensuring the damping effect.

[0041] Workflow: When the lidar 101 is mounted on the drone 115 for measurement, the damping block 106 reduces the vibration of the drone 115 on the lidar 101, thereby ensuring more accurate measurements. When the damping block 106 wears down, reducing its damping effect, the bolt 109 is tightened with an open-end wrench. The bolt 109 moves the drive block 110, and the first slider 116 moves along the first groove 103a. Therefore, the drive block 110, through the first inclined surface 110a and the second inclined surface 112a, moves the transmission block 112 and the first slider 116 along the first groove 103a, thereby adjusting the position of the damping block 106 and ensuring the friction between the damping block 106 and the guide block 102, thus ensuring the damping effect.

[0042] Second embodiment:

[0043] The difference from the first embodiment is that the support column 114 is fixed on the first slide plate 103, so that the lidar 101 can be directly damped by the damping block 106 on the first slider 116, thereby ensuring measurement accuracy.
