Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) technology, specifically to an AGV-mounted lidar mounting structure. Background Technology

[0002] AGVs are transport vehicles that can automatically travel along a preset path. They utilize various navigation technologies, such as magnetic strip navigation, QR code navigation, laser navigation, and visual navigation, to achieve unmanned driving and autonomous operation. AGVs are widely used in manufacturing, warehousing and logistics, port terminals and other fields for handling, transportation, loading and unloading operations. They can improve efficiency, reduce costs, reduce human error, and improve the working environment.

[0003] LiDAR is a sensor that uses lasers to measure distance and can acquire three-dimensional information about the surrounding environment. Combining LiDAR with AGVs (Automated Guided Vehicles) can achieve more accurate and flexible navigation and obstacle avoidance, improving the intelligence level of AGVs. LiDAR can scan the surrounding environment and generate high-precision three-dimensional maps, providing more accurate navigation information for AGVs. It can detect surrounding obstacles in real time and adjust the AGV's driving path according to the distance and speed of the obstacles to avoid collisions. It can perceive changes in the surrounding environment in real time and dynamically adjust the AGV's driving path according to the changes, improving the flexibility and efficiency of path planning. LiDAR can be installed on the roof, side, or front of the AGV. During installation, it is necessary to select an appropriate field of view based on the AGV's usage scenario and obstacle avoidance requirements to ensure that the installation of LiDAR does not affect the driving safety and stability of the AGV.

[0004] Existing technologies typically use mounting structures to clamp and install radar components, which limits the radar's scanning range. At the same time, the AGV vehicle body needs to ensure good stability while being clamped during operation. Therefore, we have improved the aforementioned existing technologies based on actual usage.

The drive motor 6 is an existing mechanism and is connected to a power source via wires. The power source can be installed on the AGV vehicle body (not shown in the figure). Its structure and working principle can be directly obtained and it can be purchased directly on the market. The turntable 2 is driven to rotate by the kinetic energy provided by the drive motor 6. Two sets of identical connecting legs 7 are symmetrically installed on the outer walls of both sides of the base 1 to install the entire device on the AGV vehicle body.

[0035] Turntable 2, with a base plate 3 mounted on top of it. The base plate 3 has a square structure.

[0036] The base plate 3 has two sets of identical protective plates 4 symmetrically installed on both sides of its top.

[0037] The protective plate 4 has two sets of identical clamping assemblies 5 movably mounted on its top left and right sides. The clamping assemblies 5 hold the LiDAR body 8. The LiDAR body 8 is a prior art technology that scans the surrounding environment to generate a high-precision 3D map, providing more accurate navigation information for the AGV vehicle. It will not be described in detail. The bottom of the clamping assembly 5 is tightly fitted to the top of the LiDAR body 8.

[0043] Preferably, the limiting vertical plate 42 includes a square vertical plate 421, and the top of the base plate 3 is provided with a square vertical groove that matches the square vertical plate 421 to limit the vertical installation of the square vertical plate 421. A sliding button 422 is connected to the front outer wall of the square vertical plate 421, and T-shaped sliding strips 423 are connected to the two outer walls of the square vertical plate 421. A T-shaped sliding groove that matches the T-shaped sliding strip 423 is provided on the inner wall of the insertion groove 41, and a second spring 424 is connected to the top of the square vertical plate 421. The top of the second spring 424 is connected to the top inner wall of the insertion groove 41. Similarly, if necessary, screw holes can be made on the base plate 3 to pass through and connect screws to the square vertical plate 421 for fixing.

[0044] It should be noted that you should refer to [link / reference]. Figure 1 and Figure 4 and Figure 5When the operator needs to install the lidar body 8, push the sliding button 422 upwards to disengage the square vertical plate 421 from the square vertical groove.

After the operator places the lidar body 8 into the placement groove of the base plate 3, close the guard plate 4 and keep it vertical. Push the sliding button 422 upwards again to insert the square vertical plate 421 into the square vertical groove. With the help of the second spring 424, the square vertical plate 421 is abutted against the square vertical groove. At the same time, push the folding plate 51 upwards to lock the rubber plate 53 on the folding plate 51 onto the top outer wall of the lidar body 8. With the help of the first spring 55, the lidar body 8 is tightened to ensure its stability during the operation of the AGV and prevent it from falling and being damaged.

[0045] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0046] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
