The elastic connecting plate 102 first deforms to reduce the impact. At the same time, the connecting column 404 and the damping sleeve 403 will slide relatively, so that the spring 405 is compressed or stretched.

When the connecting rod 502 rotates around the fixed shaft 501, the sliding block 504 slides on the guide rod 601, dispersing the direction of the impact force. The limiting pad 602 prevents the sliding block 504 from moving excessively on the guide rod 601, so that when the robot is subjected to a large vibration, the top plate 103 will not descend excessively to damage the support frame 201, thereby prolonging the service life of the damping component.

[0029] The usage and advantages of this utility model: When this security patrol robot uses a shock-absorbing structure, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 As shown, when the robot walks on uneven ground or encounters obstacles, it generates vibration and impact, causing the distance between the base plate 101 and the top plate 103 to change. The elastic connecting plate 102 first deforms to reduce the impact, while the connecting column 404 and the damping sleeve 403 slide relative to each other, causing the spring 405 to compress or stretch. The spring 405 reduces vibration through elastic deformation, while the damping sleeve 403 reduces the amplitude of vibration through friction, thus improving the shock absorption effect. As the connecting column 404 moves, the connecting rod 502 rotates around the fixed axis 501, causing the slider 504 to slide on the guide rod 601, dispersing the direction of the impact force. The limiting pad 602 prevents the slider 504 from moving excessively on the guide rod 601, so that when the robot is subjected to large vibrations, the top plate 103 will not drop excessively and damage the support frame 201, thus extending the service life of the shock absorption components.
