Referring to fig. 1 and 2, one embodiment of the present application provides a sensor mounting bracket 10, comprising: the device comprises a connecting piece 110, a bearing piece 120, a base 130 and a spacing adjusting piece. The carrier 120 is used for fixing the sensor 20, and one end of the carrier 120 is rotatably connected with the base 130 through the connecting piece 110. The spacing adjustment member acts between the carrier 120 and the base 130 and is spaced apart from the connector 110. The spacing adjuster is used for adjusting the distance between the carrier 120 and the base 130.

In the sensor mounting bracket 10 described above, since the carrier 120 is used for fixing the sensor 20, and one end of the carrier 120 is rotatably connected to the base 130 through the connecting member 110, the sensor 20 can rotate with the carrier 120 about the central axis of the connecting member 110 relative to the base 130, but the distance between the end of the carrier 120 to which the connecting member 110 is connected and the base 130 can be kept unchanged. Meanwhile, since the distance adjusting member acts between the bearing member 120 and the base 130 and the distance adjusting member is spaced from the connecting member 110, when the inclination angle of the sensor 20 needs to be adjusted, the distance between the bearing member 120 and the base 130 needs to be changed by the distance adjusting member, so that one end of the bearing member 120 away from the connecting member 110 is close to or far from the base 130, and the bearing member 120 has different inclination angles relative to the base 130, so that the inclination angle of the sensor 20 can be adjusted.

In the present embodiment, the sensor 20 is a lidar.

Alternatively, in another embodiment, the sensor 20 may be a depth camera or a video camera, or the like.

Specifically, in the present embodiment, the carrier 120 is a plate-like structure.

Alternatively, in another embodiment, the spacing adjustment member comprises a telescoping rod. The fixed end of the telescopic rod is connected with the bottom plate 133, and the telescopic end of the telescopic rod is abutted with the bearing piece 120. Thus, the inclination angle of the carrier 120 relative to the base 130 can be adjusted.

In order to facilitate observation of the inclination angle of the carrier 120 after adjustment with respect to the base 130, in an embodiment, as shown in fig. 1, 3 and 4, the side wall of the carrier 120 is provided with an angle mark 160. The first connecting plate 131 and/or the second connecting plate 132 are provided with notches 1312. The notch 1312 is used to display the magnitude of the tilt angle of the angular adjustment of the carrier 120 in cooperation with the angular marking 160 on the carrier 120.

After the inclination angle of the bearing member 120 relative to the base 130 is adjusted, the connection between the bearing member 120 and the base 130 can be realized through the connecting screw 150, so that the stability of the sensor 20 mounted on the sensor mounting bracket 10 is improved, meanwhile, the stability of the angle of the sensor 20 can be ensured, and the inclination angle of the sensor 20 relative to the base 130 is prevented from being changed when the robot body shakes in the moving process.

Alternatively, in another embodiment, the connection between the carrier 120 and the base plate 133 may also be achieved by connecting bolts and nuts.

Specifically, since the projection position of the threaded hole 122 on the carrier 120 on the base 130 is changed when the inclination angle of the carrier 120 relative to the base 130 is changed, in order to enable the connection screw 150 to be connected with the threaded hole 122 through the through hole 1332, in this embodiment, as shown in fig. 3, the through hole 1332 is a kidney-shaped hole, and the kidney-shaped hole is disposed to extend along the direction from the connection member 110 to the spacing adjustment member.
