Description

Technical Field

[0001] The utility model relates to the technical field of robot protection, in particular to an anti-collision protection device for an intelligent robot. Background Art

[0002] An intelligent robot is a robot based on artificial intelligence technology. It uses machine learning, deep learning, natural language processing and other technologies to analyze and learn large amounts of data, simulate human behavior and thinking, and make intelligent decisions and actions. Intelligent robots are widely used in industry, agriculture, services, home care, etc., which can greatly improve work efficiency, help humans better understand themselves and the environment, and improve the quality of life. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-collision protection device for an intelligent robot, so as to solve the problem in the above-mentioned background technology that important components such as a drive structure, a sensor and a controller are installed inside the existing robot body, which are usually protected by the robot body shell. When the robot moves and collides with other objects, the robot's anti-collision buffering ability is weak, which may cause damage to the shell and internal parts, thereby reducing the service life of the robot.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-collision protection device for an intelligent robot, the anti-collision protection device is assembled on the upper surface of a mobile base to protect the outer wall of a robot body, the anti-collision protection device comprises: a force-bearing frame, the force-bearing frame is sleeved on the outside of the robot body and does not fit the outer wall of the robot body, a fixed foot is welded at the bottom end of the force-bearing frame, the fixed foot is connected to the upper surface of the mobile base by screws, and a rotating seat is welded to the top of the outer wall of one side of the force-bearing frame;

[0005] The anti-collision part is placed on the rotating seat, and the anti-collision part includes: an anti-collision plate, a rotating frame, a buffer frame and a serpentine spring. One side of the rotating frame is welded to the inner wall of the anti-collision plate, and the rotating shaft of the rotating frame is inserted into the socket of the rotating seat. The bottom of the buffer frame is welded to the upper surface of the mobile base. A serpentine spring is arranged inside the buffer frame, and the two sides of the serpentine spring are respectively welded to the anti-collision plate and the buffer frame.

[0006] By adopting the above technical solution, when the robot body moves and collides with an object head-on, the anti-collision plate will rotate under the action of the rotating frame due to the impact force, and the force will be applied from the bottom to the serpentine spring to generate compression to achieve a buffering effect. The compression of the serpentine spring weakens the force and transmits it from the buffer frame to the mobile base. At the same time, with the cooperation of the force-bearing frame, the force generated by the impact on the outer shell of the robot body is reduced, the probability of the outer shell and internal parts being damaged by impact is reduced, and the service life of the robot is increased.

[0007] Preferably, the anti-collision protection device also includes: a side buffer portion, which is placed on one side of the force-bearing frame, and the side buffer portion includes: a base plate, a small airbag, a bolt, a return spring and a buffer plate, one end of the threaded head of the bolt is inserted into the buffer plate, the return spring and the base plate in sequence, and the bolt is threadedly connected to the outer wall of one side of the force-bearing frame after being inserted, and the small airbag is adhered to one side of the base plate.

[0008] By adopting the above technical solution, when the side of the robot body is hit by a person or other object, the buffer plate will move inward, and the small airbag on the inside will provide buffering capacity. The small airbag will produce elastic deformation under the force to achieve a buffering effect. When the impact is over, the return spring pushes the buffer plate back to its original position, which can buffer the next impact, thereby improving the protective effect on the side of the robot body and reducing the probability of damage caused by impact.

[0009] Preferably, the return spring is located on the bolt at a middle position between the bottom plate and the buffer plate, and the return spring is always in a contracted state.

[0010] By adopting the above technical solution and placing the reset spring in the middle position, the contraction of the reset spring can be used to generate elastic force to push the buffer plate outward from the small airbag to ensure that it can be reset before or after an impact, so as to ensure that buffering and collision prevention can be performed at any time.

[0011] Preferably, the small airbags are interconnected blister-formed three-dimensional airbags made of polyurethane rubber, and the gas filled in a single small airbag can be deformed under strong pressure.

[0012] By adopting the above technical scheme, the small airbag made of polyurethane rubber is light in weight, can be repeatedly filled with gas many times, has a strong ability to recover to its original state after deformation, thereby increasing the service life of the small airbag. At the same time, filling a certain amount of gas can ensure the optimal cushioning capacity of the small airbag and improve the impact force cushioning effect.

[0013] Preferably, the overall shape of the anti-collision plate is semicircular, and the curvature of the interior of the buffer frame is the same as the curvature of the anti-collision plate.

[0014] By adopting the above technical solution, the anti-collision plate is designed to be semicircular in shape. After being hit, part of the force will be dispersed because the force point is on the curved surface, thereby reducing the impact force. At the same time, when the bottom of the anti-collision plate is rotated and displaced by impact, it can move along the internal channel of the curved surface, ensuring that it can smoothly act on the serpentine spring for buffering.

[0015] Preferably, the bottom end of the anti-collision plate is spaced apart from the upper surface of the movable base, and is also spaced apart from the bottom surface inside the buffer frame.

[0016] By adopting the above technical solution, since the top of the anti-collision plate rotates around the rotating seat, the displacement path of its bottom is a curve, and a certain distance is left to ensure that the anti-collision plate can smoothly compress the serpentine spring for buffering.

[0017] Preferably, the anti-collision plate and the buffer plate may be made of polyethylene material, and a rubber sheet is adhered to the outer wall of the anti-collision plate.

[0018] By adopting the above technical solution, polyethylene material is used to make anti-collision plates and buffer plates. Polyethylene material has the advantages of high toughness, strong tensile strength and high wear resistance. As the material for making anti-collision plates and buffer plates, it can well protect the robot body. At the same time, the rubber sheet can improve the protection ability of the front of the anti-collision plate against impact.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) When the robot body moves and collides with an object, the anti-collision plate will rotate under the action of the rotating frame, and the force will be applied from the bottom to the serpentine spring to generate compression to achieve a buffering effect. The serpentine spring compression weakens the force and transmits it from the buffer frame to the mobile base. At the same time, part of the force will be transmitted from the force frame to the mobile base, thereby reducing the force generated by the impact on the robot body shell, reducing the probability of damage to the shell and internal parts by impact, and increasing the service life of the robot;

[0021] (2) When the side of the robot body is hit by a person or other object, the buffer plate will move inward, and the small airbag inside will provide buffering capacity. The small airbag will produce elastic deformation under the force to achieve a buffering effect. When the impact is over, the return spring pushes the buffer plate back to its original position, which can buffer the next impact, thereby improving the protection of the side of the robot body and reducing the probability of damage caused by impact.
