[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1-Figure 8A security robot with anti-collision protection is shown, comprising a base 1, wheels 24 are rotatably mounted on both side surfaces of the base 1 near the corners, a notch 2 is provided on the front side of the base 1, a rotating shaft 3 is rotatably mounted on the inner side of the notch 2 through a driving mechanism, first folding plates 9 are fixedly connected to both sides of the front surface of the rotating shaft 3, a baffle 14 is installed at the front end of each first folding plate 9 through a buffer mechanism, an arc plate 15 is fixedly connected to the lower end of the baffle 14, a fixed plate 16 is fixedly connected to the upper end of the baffle 14, movable plates 17 are installed on the sides of the fixed plates 16 close to each other through an elastic mechanism, a curved surface 18 is provided on the rear surface of the movable plate 17, and a clamping mechanism is provided on the upper surface of the base 1;

[0029] When the front surface of the baffle 14 is hit, the rear surface of the baffle 14 is buffered by the buffer mechanism, and the rear surface of the baffle 14 is buffered by contacting the surface of the wheel 24. It has a double buffering function to achieve a better buffering effect.

[0030] like Figure 1 , Figure 2 , Figure 4 As shown, the driving mechanism includes a brake motor 4 arranged inside the notch 2, the output shaft of the brake motor 4 is fixedly connected with a drive shaft 7, the outer surface of the drive shaft 7 and the outer surface of the rotating shaft 3 are respectively fixedly sleeved with a transmission gear 8, the two transmission gears 8 are meshed with each other, the inner surface of the notch 2 is fixedly installed with a mounting plate 5 and a mounting frame 6, the front surface of the mounting plate 5 is fixedly connected with the rear surface of the brake motor 4, and the drive shaft 7 and the rotating shaft 3 are respectively rotated to penetrate the inner side of the mounting frame 6. The mounting frame 6 is used to ensure the stable installation of the rotating shaft 3 and the drive shaft 7. When the brake motor 4 rotates, the two transmission gears 8 act on each other, so that the power is transmitted to the rotating shaft 3.

[0031] The inner surface of the notch 2 is fixedly connected with a protective cover 32, which is sleeved on the outer side of the mounting frame 6 and the transmission gear 8, and the rotating shaft 3 and the driving shaft 7 rotate and penetrate the side surface of the protective cover 32. The protective cover 32 plays a protective role, preventing the transmission gear 8 from being difficult to transmit normally after impurities adhere to the surface of the transmission gear 8.

[0032] like Figure 4 , Figure 5As shown, the elastic mechanism includes a plurality of fixed cylinders 19 fixedly connected to the rear surface of the baffle 14 through a mounting sleeve 23, a connecting rod 21 is slidably inserted on one side of the fixed cylinder 19, one end of the connecting rod 21 is fixedly connected to the surface of one side of the movable plate 17, and the other end of the connecting rod 21 is fixedly connected to a sliding disk 22, the sliding disk 22 is slidably matched with the inner wall of the fixed cylinder 19, and a compression spring 20 is arranged on the inner side of the fixed cylinder 19, and the compression spring 20 is in contact with the surface of one side of the sliding disk 22. When the curved surface 18 contacts an object, the movable plate 17 can be pushed, and after leaving the object, the sliding disk 22 is pushed under the elastic force of the compression spring 20, thereby resetting the movable plate 17, ensuring that the fixed plate 16 and the movable plate 17 cover a larger span together to guide the wires.

[0033] like Figure 3 As shown, a driving motor 25 is fixedly mounted on one side of the lower surface of the base 1 corresponding to each wheel 24, and the output shaft of the driving motor 25 is fixedly connected to the central axis of the wheel 24. The driving motor 25 is used to drive the wheel 24 to rotate to control the movement of the base 1. Obviously, by controlling the independent operating speeds of the four driving motors 25, the turning of the base 1 can be achieved.

[0034] like Figure 7 As shown, the clamping mechanism includes a fixed clamping plate 29 fixedly mounted on the upper surface of the base 1, a movable clamping plate 28 is arranged on the rear surface of the fixed clamping plate 29, a mobile frame 27 is fixedly connected to the rear surface of the movable clamping plate 28, and a telescopic cylinder 26 is fixedly mounted on the lower surface of the base 1, and the telescopic end of the telescopic cylinder 26 is fixedly connected to the lower end of the front surface of the mobile frame 27. The telescopic cylinder 26 can be an electric cylinder, which can be used to clamp objects with relatively light force.

[0035] like Figure 1 , Figure 7 As shown, an inspection module 30 is provided at the front end of the upper surface of the base 1, and a battery 31 is fixedly installed on the upper surface of the base 1 and near the rear of the inspection module 30. The base 1 can be a common workshop inspection robot, which can sense the surrounding environment through technologies such as laser radar, infrared sensor, GPS or indoor positioning system, and move according to a preset route or an autonomously planned path. This autonomous navigation capability enables the robot to complete the inspection task autonomously without human intervention. The inspection module 30 is a high-definition camera that is often equipped with an inspection robot, which can capture and record various details in the workshop in real time, including equipment status, personnel activities, safety hazards, etc. These image records can be used for post-analysis and problem troubleshooting. The establishment of the battery 31 supplies power to the electrical components to ensure the normal operation of the electrical components.

[0036] like Figure 5 , Figure 6As shown, the buffer mechanism includes a second folding plate 11 fixedly connected to the lower end of the rear surface of the baffle 14, a plurality of plug plates 10 are fixedly connected to the front surface of the first folding plate 9, the plug plates 10 slide through the rear surface of the baffle 14, a T-shaped column 13 is fixedly connected to the rear surface of the second folding plate 11, the T-shaped column 13 slides through the front surface of the first folding plate 9, and a buffer spring 12 is sleeved on the outer surface of the T-shaped column 13, and the buffer spring 12 is located between the first folding plate 9 and the second folding plate 11.

[0037] The base 1 moves with the help of the rotating wheels 24. When there are electric wires in front, the electric wires contact the front surface of the baffle 14, the fixed plate 16 or the movable plate 17, and are guided downward at an angle, sliding down along the surface of the curved plate 15, and can then be pressed by the wheels 24 to ensure that the base 1 can move over the surface of the electric wires. Therefore, the inspection robot can move on the road surface where electric wires are laid to prevent obstruction.

[0038] When touching the wires, when the wires are laid taut or are thick, the baffle 14 will be subjected to a certain impact. At this time, the second folding plate 11 will move backwards to squeeze the buffer spring 12. At the same time, the rear surfaces of the baffle 14 and the arc plate 15 contact the wheel 24. Since the surface of the wheel 24 is made of rubber, it also provides a certain buffering effect to prevent the force from being dispersed too much to the base 1 during the impact and causing damage.

[0039] During normal travel, the brake motor 4 is controlled to rotate, so that the shaft 3 rotates, and then the baffle 14 rotates upward until the baffle 14 is parallel to the upper surface of the base 1. At this time, the state is as follows: Figure 8 As shown, it can prevent debris from splashing on the surface of the wheel 24, which is a common state during use.

[0040] By controlling the extension and retraction of the telescopic cylinder 26, the movable clamping plate 28 is moved and adjusted in position along the front-rear direction, thereby ensuring that the object can be clamped between the movable clamping plate 28 and the fixed clamping plate 29. During the rotation of the rotating shaft 3, the curved surface 18 on the movable plate 17 will contact the surface of the object, forming a pushing effect, thereby ensuring that the object can be located near the middle position on the upper surface of the base 1, and will not deviate to both sides as it moves. By adopting this solution, the object can be clamped with a lower force to prevent the object from being damaged.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
