[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0020] Please refer to Figures 1-4 , a protective bracket for a machine dog lidar sensor, including a machine dog 1, an industrial control computer 2 is detachably installed on the top of the machine dog 1, a mounting plate 3 is fixedly connected to the top of the industrial control computer 2, a guiding hole 4 is opened on the top of the mounting plate 3, a guiding rod 5 is movably inserted into the inner side of the guiding hole 4, a lidar 6 is fixedly connected to the top of the guiding rod 5, a clamping member is arranged on the lidar 6, and a limiting mechanism is arranged on the mounting plate 3.
[0021] Through the above technical solution, during the use of the device, the machine dog 1 carries the industrial control computer 2 and the lidar 6 for information detection and processing. During this process, the peripheral protective frame 15 plays an excellent protective effect, and the clamping member cooperates with the limiting mechanism to keep the lidar 6 relatively stable during use, avoiding unstable conditions such as shaking during the running of the machine dog 1.
[0022] Specifically, the clamping member includes a triangular insertion block 8 fixedly connected to the bottom of the lidar 6, and an embedding groove 9 is opened on the outer surface of the triangular insertion block 8.
[0023] Through the above technical solution, the embedding groove 9 is designed to cooperate with the adapter card frame 14, and the two can just be completely fitted.
[0024] Specifically, the limiting mechanism includes a triangular limiting hole 7 opened on the top of the mounting plate 3, and the inner side of the triangular limiting hole 7 is movably inserted into the outer surface of the triangular insertion block 8.
[0025] Through the above technical solution, when the triangular insertion block 8 is inserted into the triangular limiting hole 7, the pull button 12 needs to be toggled first to avoid the adapter card frame 14 affecting the smooth downward movement of the triangular insertion block 8.
[0026] Specifically, a fixing rod 10 is fixedly connected to the top of the mounting plate 3, and a telescopic shaft 11 is movably inserted into the inner side of the fixing rod 10.
[0027] Through the above technical solution, during the elastic deformation of the spring 13, the telescopic shaft 11 will be pushed to expand and contract along the inner side of the fixing rod 10 to adjust the position of the adapter card frame 14.
[0028] Specifically, a pull button 12 is fixedly connected to one end of the telescopic shaft 11, a spring 13 is movably sleeved on the outer surface of the telescopic shaft 11, and an adapter card frame 14 is arranged at the end of the telescopic shaft 11 away from the pull button 12.
[0029] With the above technical solution, on the one hand, the pull button 12 can facilitate the direct manual operation of the position of the telescopic shaft 11, and on the other hand, it can also prevent the telescopic shaft 11 from detaching from the fixed rod 10.
[0030] Specifically, a peripheral protective frame 15 is provided on the top of the mounting plate 3.
[0031] With the above technical solution, the peripheral protective frame 15 is arranged around the lidar 6, providing a good protection effect for it, and both ends of the peripheral protective frame 15 are unobstructed, avoiding hindering the detection of the lidar 6.
[0032] Working principle: During the use of the device, the robot dog 1 carries the industrial control computer 2 and the lidar 6 for information detection and processing. The lidar 6 can detect the front situation in real time and transmit the information back to the industrial control computer 2. Through complex data processing and analysis by the industrial control computer 2, it helps the robot dog 1 make intelligent decisions, such as path planning and obstacle avoidance. During the running process of the robot dog 1 carrying the lidar 6, in order to avoid shaking of the lidar 6 and also to avoid damage to the sensors inside the radar when the robot dog 1 accidentally falls, the peripheral protective frame 15 is designed. It can effectively protect the lidar 6 and prevent the lidar 6 from directly contacting the ground when the robot dog 1 falls. And when installing the lidar 6, effective limit and anti-shaking measures have been taken. That is, during installation, the guide rod 5 is first inserted into the guide hole 4, and at the same time, the triangular insertion block 8 is inserted into the triangular limit hole 7. The guide rod 5 cooperates with the triangular insertion block 8 to stably support the lidar 6. During this process, the pull button 12 needs to be pulled to make the telescopic shaft 11 drive the adapter bracket 14 away from the triangular insertion block 8. During this process, the spring sleeve 13 will be compressed. When the triangular insertion block 8 is completely inserted into the triangular limit hole 7, the pull button 12 is released. Under the elastic reset action of the spring 13, the adapter bracket 14 can be completely embedded into the clamping groove 9 on the surface of the triangular insertion block 8, thereby effectively limiting the triangular insertion block 8 and avoiding unstable conditions such as shaking during the running process of the robot dog 1, improving the use safety and stability.
[0033] In summary, by introducing the peripheral protective frame 15 and the stable support structure, as well as optimizing the data processing and analysis capabilities, the robot dog 1 system in this application not only improves the operation safety and stability, but also effectively reduces the risk of damage to the lidar 6, making the overall system more reliable and meeting the requirements of complex environments.
