[0023] Refer to Figure 1 and Figures 3 - 6, in a preferred embodiment, the centrifugal counterweight module 5 further includes a mounting bracket 518. The mounting bracket 518 is fixedly connected to the top of the robot body 1. The same mounting rod 517 is movably connected to the inner walls on both sides of the mounting bracket 518.

[0024] Specifically, when turning, the eccentric member 512 inside the centrifugal bin 504 on one side will be subjected to an outward centrifugal force and move on the guiding rod 506, causing the telescopic spring 511 to compress. As the eccentric member 512 moves, it will drive the contact ring 513 to move and contact the triggering device 509 (the magnitude of the centrifugal force can be judged according to the number of contacts). At this time, the triggering device 509 transmits the signal to the inside of the receiving device 507 through the transmission line 510, and the receiving device 507 conveys the signal to the inside of the control device 516, and further controls the operation of the driving motor 514 through the control wiring 515, so that the driving motor 514 drives the mounting rod 517 and the counterweight 501 to rotate and rotate to the opposite side of the operating eccentric member 512 to complete the lateral counterweight compensation; In a specific application scenario, the centrifugal counterweight module 5 is applicable to the turning link of the wheel-legged robot, that is, the centrifugal counterweight module 5 can perform lateral counterweight compensation on the wheel-legged robot during the turning operation, so that the center of gravity of the wheel-legged robot moves inward during turning, thereby offsetting the outward centrifugal force generated during turning, so that the center of gravity of the wheel-legged robot remains within a stable range during turning, thus avoiding excessive offset of the center of gravity of the wheel-legged robot during turning, improving the stability and balance of the wheel-legged robot during turning, and further avoiding the situation of the wheel-legged robot tipping over or colliding with objects on both sides, and further avoiding its damage and improving the use effect of the device.

[0025] Refer to Figure 2 and Figures 7 - 10, in a preferred embodiment, the counterweight compensation module 10 further includes a fixed frame 1003, the fixed frame 1003 is fixedly connected to the bottom of the robot body 1, and three counterweight water tanks 1013 are arranged inside the fixed frame 1003. One outer wall of the three counterweight water tanks 1013 is connected to the same communication chamber 1012 through a pipeline. Two connecting pipe fittings 1011 are fixedly connected to the outer wall of the communication chamber 1012. One end of each of the two connecting pipe fittings 1011 is fixedly connected to a delivery pump 1009 and a reflux pump 1010 respectively, and both the delivery pump 1009 and the reflux pump 1010 are fixedly connected to the bottom of the fixed frame 1003; Side frames 1001 are fixedly connected to both outer walls of the counterweight battery 4, the counterweight bin 1002 is fixedly connected to the inner walls of the opposite sides of the two side frames 1001, two telescopic spring rods 1015 are arranged inside the counterweight bin 1002, and one end of each of the two telescopic spring rods 1015 is fixedly connected to the same movable plate member 1014. The outer wall of the movable plate member 1014 is in contact with the inner wall of the counterweight bin 1002, and the output end of the delivery pump 1009 is fixedly connected to a delivery pipe 1004 and a compensation through pipe 1007. The input end of the reflux pump 1010 is fixedly connected to a first reflux pipe 1005 and a second reflux pipe 1006. Control valves 1008 are arranged on the outer walls of the first reflux pipe 1005, the second reflux pipe 1006, the delivery pipe 1004 and the compensation through pipe 1007; One ends of the second reflux pipe 1006 and the compensation through pipe 1007 are both communicated with the inside of the counterweight bin 1002. One end of the delivery pipe 1004 and the first reflux pipe 1005 are fixedly connected to the same through pipe fitting 1016. The two ends of the through pipe fitting 1016 are respectively communicated with the inside of the two telescopic compensation bins 1018, and a fixed ring frame 1021 is fixedly connected to the outer wall of the working base 11. Four round holes are formed in the top of the fixed ring frame 1021; The inner walls of the four round holes are all movably connected with fixed rods 1020. The bottom ends of the four fixed rods 1020 are fixedly connected to the same mounting plate member 1017. The two telescopic compensation bins 1018 are both fixedly connected to the top of the mounting plate member 1017, and reset springs 1019 are arranged on the outer walls of the four fixed rods 1020.

[0026] Specifically, when counterweighting, start the delivery pump 1009 and open the control valve 1008 on the compensation through pipe 1007. At this time, the delivery pump 1009 can transport the water inside the communication chamber 1012 to the inside of the compensation through pipe 1007 through the connecting pipe fitting 1011 and further transport it to the inside of the counterweight bin 1002. As the water flow increases, the telescopic spring rods 1015 inside the counterweight bin 1002 are compressed, and the movable plate member 1014 is moved to increase the counterweight mass. When replacing the working device, start the delivery pump 1009 and open the control valve 1008 on the delivery pipe 1004, so that the delivery pump 1009 delivers water through the delivery pipe 1004 into the inside of the through fitting 1016, and further into the inside of the telescopic compensation bin 1018, causing it to expand. At this time, the return spring 1019 is compressed, and as the working device is disassembled and replaced, the counterweight mass at the working end is gradually increased until the replacement of the working device is completed; After the operation, the return pump 1010 operates and, in cooperation with the second return pipe 1006 and the first return pipe 1005, can respectively deliver the water inside the counterweight bin 1002 and the telescopic compensation bin 1018 back into the counterweight water bin 1013 for subsequent counterweight compensation operations; In a specific application scenario, the counterweight compensation module 10 is applicable to the counterweight load adjustment link, that is, when the counterweight compensation module 10 is in use, it can increase the counterweight mass of the counterweight battery 4, thereby increasing the load mass at the operation base 11, and further increasing the counterweight stable load of the wheel-legged robot, enabling the wheel-legged robot to perform operation tasks on higher-quality objects, improving the use effect of the device. Moreover, the operation base 11 can replace the working device according to operation requirements during use. During this process, the device can compensate for the mass at the working end through the telescopic compensation bin 1018 to prevent the wheel-legged robot from becoming unstable when replacing the working device.

[0027] Working principle: When steering, the eccentric member 512 inside the centrifugal bin 504 on one side will be subjected to an outward centrifugal force and move on the guiding rod member 506, causing the telescopic spring 511 to be compressed. As the eccentric member 512 moves, it will drive the contact ring 513 to move and contact the triggering device 509. At this time, the triggering device 509 transmits a signal through the transmission line 510 into the receiving device 507, and through the receiving device 507, the signal is transmitted into the controller device 516, and further controls the driving motor 514 to operate through the control wiring 515, so that the driving motor 514 drives the installation rod member 517 and the counterweight block 501 to rotate and rotate to the opposite side of the operating eccentric member 512 to complete lateral counterweight compensation; When counterweighting, start the delivery pump 1009 and open the control valve 1008 on the compensation through pipe 1007. At this time, the delivery pump 1009 can deliver the water inside the communication bin 1012 into the compensation through pipe 1007 through the connecting fitting 1011, and further into the counterweight bin 1002. As the water flow increases, the telescopic spring rod 1015 inside the counterweight bin 1002 is compressed, causing the movable plate member 1014 to move to increase the counterweight mass; When replacing the working device, start the transfer pump 1009 and open the control valve 1008 on the transfer pipe 1004, so that the transfer pump 1009 conveys water through the transfer pipe 1004 into the inside of the through fitting 1016, and further conveys it into the inside of the expansion compensation bin 1018 and causes it to expand. At this time, the return spring 1019 is compressed, and as the working device is disassembled and replaced, the counterweight mass at the working end is gradually increased until the replacement of the working device is completed.
