Technical Field

[0001] The utility model relates to the technical field of vehicle robot standing structures, in particular to a robot standing structure with a constraint component. Background Technique

[0002] A robot is a machine device that automatically performs work. The robot base is one of the core components of the robot, and the robot base can enable the robot to walk.

[0003] Existing robots are prone to being collided by the outside world during the self - moving process. After being collided, due to the lack of a constraint component, their center of gravity is unstable due to inertia, and thus they are prone to tipping over, causing damage to the robots and affecting their subsequent use performance, resulting in a lower service life. Therefore, there is an urgent need for a robot standing structure with a constraint component to solve the above problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a robot standing structure with a constraint component.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

A turntable is fixed on the output shaft of the servo motor. A U - shaped support is fixed on the upper end of the turntable. A bearing shaft is installed between the supports. Two groups of levers are symmetrically fixed at both ends of the bearing shaft. One side of the upper end of each lever is fixed with a convex block. Chamfers are made at both ends of the upper end of the convex block. A film - type pressure sensor is arranged on the surface of one of the chamfers. A concave cavity is opened at the bottom end of the lever. A driving motor is fixed on one side inside the concave cavity. A screw rod is fixed on the output shaft of the driving motor. A screw block is sleeved on the screw rod. A counterweight is fixed at the bottom end of the screw block.

[0008] Preferably, the support is welded on the turntable, the bearing shaft is rotatably installed in the support, and the levers are symmetrically welded at both ends of the bearing shaft.

[0009] Preferably, the convex block is welded at one end of the lever, and the film - type pressure sensor is adhered to the convex block.

[0010] Preferably, the concave cavity is formed at the bottom end of the lever. The output shaft of the driving motor is fixedly connected to one end of the screw rod.

[0022] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. However, the embodiments of the present utility model are not limited thereto.

[0023] As Figures 1 - 5 shown, a robot standing structure with a restraint assembly provided in this embodiment includes a base 2. The base 2 has a hollow structure inside. A servo motor 4 is installed in the middle of the bottom end of the base 2. A turntable 7 is fixed on the output shaft of the servo motor 4. A U-shaped support 10 is fixed on the upper end of the turntable 7. A bearing shaft 9 is installed between the supports 10. Two groups of levers 8 are symmetrically fixed at both ends of the bearing shaft 9. A convex block 13 is fixed on one side of the upper end of the lever 8. Chamfers are made at both ends of the upper end of the convex block 13. A film type pressure sensor 12 is arranged on one of the chamfer surfaces. A concave cavity 14 is opened at the bottom end of the lever 8. A driving motor 15 is fixed on one side inside the concave cavity 14. A screw 16 is fixed on the output shaft of the driving motor 15. A screw block 17 is sleeved on the screw 16. A counterweight 11 is fixed at the bottom end of the screw block 17.

[0024] The servo motor 4 is fixed on the bottom wall of the base 2 by bolts. The output shaft of the servo motor 4 is fixedly connected with the turntable 7. During the self-movement process of the robot, the servo motor 4 adjusts the lever 8 to the orientation consistent with its moving direction through the turntable 7.

[0025] The support 10 is welded on the turntable 7. The bearing shaft 9 is rotatably installed inside the support 10. The levers 8 are symmetrically welded at both ends of the bearing shaft 9. When a collision causes the robot to be about to tip over, due to the seesaw principle of the lever 8, one group of levers 8 will move downward and the other group of levers 8 will move upward due to unstable center of gravity.

[0026] The convex block 13 is welded at one end of the lever 8. The film type pressure sensor 12 is bonded to the convex block 13. The convex block 13 at the upward moving end of the lever 8 will collide with the bearing plate 1. The film type pressure sensor 12 can detect its pressure signal and then control the corresponding driving motor 15 to work through the electronic control mechanism of the robot.

[0027] A concave cavity 14 is formed at the bottom end of the lever 8. The output shaft of the driving motor 15 is fixedly connected to one end of the screw 16. The other end of the screw 16 is rotatably connected to the concave cavity 14. The screw block 17 is threadedly connected to the screw 16. The screw block 17 is slidably connected to the concave cavity 14. The counterweight 11 is fixed to the bottom end of the screw block 17 by screws. The driving motor 15 drives the screw 16 to rotate, so that the screw block 17 drives the counterweight 11 to move to adjust the center of gravity of the robot, which can effectively restrain the tipping and rolling of the robot and improve its service life.

[0028] A conductive ring 6 is arranged outside the turntable 7. The outer diameter of the conductive ring 6 is larger than the diameter of the turntable 7. A conductive block 5 is fixed on one side wall of the turntable 7. The conductive block 5 is in contact with the conductive ring 6. The conductive block 5 is electrically connected to both the thin-film pressure sensor 12 and the driving motor 15. The combination of the conductive ring 6 and the conductive block 5 provides the required electrical energy for the thin-film pressure sensor 12 and the driving motor 15.

[0029] A plurality of groups of electric wheels 3 are fixedly arranged in a circumferential manner at the bottom end of the base 2. A bearing plate 1 is fixedly arranged inside the upper end of the base 2. Mounting holes are formed in the upper end of the bearing plate 1. The robot can be fixed on the bearing plate 1 through the mounting holes. The electric rollers enable the robot to move by itself.

[0030] The working principle of this device: First, fix the robot on the bearing plate 1 through the mounting holes, and connect the electrical components in the base 2 to the control mechanism of the robot. Then, the electric rollers enable the robot to move by itself. During the self-movement of the robot, the servo motor 4 adjusts the lever 8 to the orientation consistent with its moving direction through the turntable 7. When a collision causes the robot to be about to tip and roll over, due to the seesaw principle of the lever 8, one group of levers 8 will move downward and the other group of levers 8 will move upward due to unstable center of gravity. The convex block 13 at one end of the upward-moving lever 8 will collide with the bearing plate 1. The thin-film pressure sensor 12 can detect its pressure signal and then control the corresponding driving motor 15 to work through the electric control mechanism of the robot, so that it drives the screw 16 to rotate and the screw block 17 drives the counterweight 11 to move to adjust the center of gravity of the robot, which can effectively restrain the tipping and rolling of the robot and improve its service life.

[0031] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
