Through the above technical solution, the impact resistance of the base of the inspection robot is enhanced, and the influence caused by the collision on the inspection robot is reduced.

[0004] However, when the existing robot encounters an inclined road surface, the robot tilts. Due to the heavy weight at the upper end of the base, it is easy to topple over when tilted, resulting in low balance performance. Therefore, it does not meet the existing requirements. For this reason, we propose a robot with a bottom balance structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a robot with a bottom balance structure to solve the problem that when the existing robot encounters an inclined road surface, the robot tilts.

[0015] Preferably, a maintenance opening is provided on one side surface of the robot body, an maintenance plate is provided at the opening of the maintenance opening, and the maintenance plate is fixed to the robot body by screws.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model sets a mounting groove at the center of the lower surface of the base, puts the two-way cylinder into the mounting groove of the base, and the fixing plate is threadedly connected with the top surface of the mounting groove by fixing screws, so as to fix the two-way cylinder and the base, and then puts the weight-added object into the weight-added cavity, covers the sealing plate, covers the protective plate, and fixes the protective plate with the connecting column thread by fixing screws to seal the mounting groove, so as to avoid damage to the two-way cylinder when the robot moves, thereby improving safety and protection. A gyroscope is installed in the robot for detecting the tilt. When the tilt is detected, an electrical signal is transmitted to the controller, and the electrical signal is transmitted to the two-way cylinder by the controller, so as to drive the moving seat in the tilt direction to move, so as to realize the movement of the weight-added object in the tilt direction, and also increase the weight in the tilt direction, so that it is not easy to dump to the other side due to the weight of the robot body and cause the center of gravity to be unbalanced, thereby improving stability and balance performance, and solving the problem that the existing robot tilts when encountering an inclined road surface, and the robot is prone to dumping when tilting due to the weight on the upper end of the base, resulting in low balance performance.

There is a gyroscope installed in the robot itself, which is used to detect tilting. When tilting is detected, an electrical signal is transmitted to the controller, and through the controller, an electrical signal is transmitted to the bi - directional cylinder 8, driving the moving seat 11 in the tilting direction to move. Thus, the weight moves in the tilting direction, increasing the weight in the tilting direction, and making it less likely to topple to the other side due to the weight of the robot body 1, resulting in a center - of - gravity imbalance and causing a toppling phenomenon, improving stability and balance performance.

[0030] Please refer to Figure 3 、 4 On both sides of the top end inside the weight - adding chamber 14, screw holes 15 are provided, and the screw holes 15 communicate with the weight - adding chamber 14.

Through the bi - directional cylinder 8, the moving seat 11 in the tilting direction is driven to move. Thus, the weight moves in the tilting direction, increasing the weight in the tilting direction, and making it less likely to topple to the other side due to the weight of the robot body 1, resulting in a center - of - gravity imbalance and causing a toppling phenomenon, improving stability and balance performance.

[0032] Please refer to Figure 2 、 3 At the corners of the installation groove 5, connecting columns 13 are provided, and the connecting columns 13 are heat - melted and fixed to the top surface of the installation groove 5.

[0035] Working principle: When in use, put the two-way cylinder 8 into the mounting groove 5 of the base 2, and the fixing plate 9 is threadedly connected to the top surface of the mounting groove 5 through the fixing screws 10, so as to fix the two-way cylinder 8 to the base 2, and then put the weighted object into the weighted cavity 14, cover the sealing plate 12, and fix the two ends of the sealing plate 12 with the screw holes 15 through external screws. The opening of the weighted cavity 14 is sealed by the sealing plate 12 to prevent the weighted object from falling, improve stability, and facilitate disassembly to adjust the weight of the weighted object, improve flexibility, cover the protective plate 6, and the protective plate 6 is connected to the connecting plate 14 through the fixing screws 7. The column 13 is threadedly fixed to seal the mounting groove 5 to avoid damage to the two-way cylinder 8 when the robot moves, thereby improving safety and protection. A gyroscope is installed in the robot to detect tilt. When tilt is detected, an electrical signal is transmitted to the controller, which transmits an electrical signal to the two-way cylinder 8 to drive the moving seat 11 in the tilt direction to move, thereby realizing the movement of the weighted object in the tilt direction, thereby increasing the weight in the tilt direction, making it less likely to tip over to the other side due to the imbalance of the center of gravity due to the weight of the robot body 1, thereby improving stability and balance performance.
