Description

Technical Field

[0001] This utility model relates to the field of laser ranging technology, specifically to a robot laser ranging detection and positioning auxiliary structure. Background Technology

[0002] Robotic laser ranging is an advanced ranging technology implemented using lidar (LiDAR), widely used in fields such as robotic vacuum cleaners and autonomous vehicles. LiDAR measures the distance and position of surrounding objects by emitting laser beams and receiving reflected signals.

[0003] LiDAR (Light Detection and Ranging) systems emit laser beams and receive the laser signals reflected from the surface of objects, thereby quickly and accurately creating a three-dimensional map of the surrounding environment. Their working principle is based on the propagation characteristics of light; by precisely measuring parameters such as the time of flight or frequency changes of light, they achieve accurate perception of information such as the distance, orientation, and speed of target objects.

[0004] Conventional auxiliary positioning structures, due to their structural limitations, require the production of matching laser ranging devices with different structures. This results in higher usage costs and relatively limited flexibility and convenience in their use, thus lacking in overall efficiency and practicality. Utility Model Content

[0005] The purpose of this invention is to provide a robot laser ranging and detection auxiliary positioning structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robot laser ranging and detection auxiliary positioning structure, comprising an adjusting base assembly and a positioning frame assembly. A movable stage assembly is mounted on the top of the adjusting base assembly, and a positioning stage component is mounted on the top of the movable stage assembly. The positioning frame assembly is symmetrically mounted on the sides of the positioning stage component. The positioning frame assembly includes a fixed frame, a first adjusting screw, a movable frame, a second adjusting screw, and a limiting pad. The first adjusting screw is vertically mounted on one side of the fixed frame, and the upper end of the first adjusting screw is connected to the movable frame.

[0009] Furthermore, the mobile platform assembly includes a platform body, a first side plate, a second side plate, and a limiting bolt. The first side plate is provided on the side of the platform body away from the positioning platform component, and the second side plate is provided on both the front and rear sides of the platform body. Moreover, the lower ends of both the front and rear sides of the platform body are horizontally installed with limiting bolts.

[0010] Furthermore, the pedestal body, the first side plate, and the second side plate are integrally formed, and the limiting bolt and the pedestal body are threaded together. Moreover, the bottom of the pedestal body and the guide rail are connected to each other by a slotted embedded structure.

[0011] Furthermore, the positioning platform component includes an upper platform, an upper mounting hole, a lower platform, and a lower mounting hole.

The lower platform 303 is arranged in an "H" shape and is an integral structure with the upper platform 301. The fixed frame 401 is movably connected to the upper platform 301. The first adjusting screw 402 and the fixed frame 401 are connected by a bearing seat structure. The movable frame 403 and the second adjusting screw 404 are threadedly connected to the first adjusting screw 402. Vertically turning the first adjusting screw 402 allows the movable frame 403 connected to the surface to move up and down in the vertical direction. Horizontally turning the second adjusting screw 404 can drive the limit pad 405 connected to it to move horizontally.

[0025] like Figures 1 to 5As shown, the adjusting base assembly 1 includes a base body 101, a fixed seat 102, a guide rail 103, and a scale mark 104. Fixed seats 102 are provided at both the left and right ends of the base body 101, and a guide rail 103 is horizontally mounted on the top of the base body 101. A scale mark 104 is provided on one edge of the top of the base body 101. The fixed seat 102 and the base body 101 are integrally formed, and holes for bolt installation are provided at both ends of the fixed seat 102.
