[0001] The utility model relates to the technical field of anti-collision buffering, in particular to an anti-collision buffering structure for a mobile robot. Background Art

[0002] A mobile robot is a machine device that performs work automatically. It has a high degree of autonomous planning, self-organization and self-adaptation capabilities. It is suitable for working in complex unstructured environments. It has multiple functions such as environmental perception, dynamic decision-making and planning, behavior control and execution. It can replace humans in dangerous and harsh environments and environments that humans cannot reach, and it shows greater mobility and flexibility than ordinary robots.

[0003] Most of the current mobile robots do not have anti-collision buffer structures on their bases, which makes it easy for internal components to be damaged or loosened due to the impact force when the mobile robots collide with other objects during movement, causing the mobile robots to be unable to work normally and require repair and replacement, which reduces the service life of internal components. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-collision buffer structure for a mobile robot to solve the problems raised in the above background technology.

[0006] As a further preferred embodiment of the technical solution, two clamping plates are fixedly connected to one side of the mounting plate and near the upper edge, circular through holes are penetrated through the top of the two clamping plates, and fixing through holes are penetrated through the top of the clamping seat and located inside the two circular through holes, fixing bolts are inserted into the two circular through holes, and the other ends of the two fixing bolts are respectively inserted into the two fixing through holes, and a plurality of elastic clamps are fixedly connected to the bottom ends of the two fixing bolts, and the outer surfaces of the plurality of elastic clamps are clamped into the inside of the fixing through holes.

[0007] As a further preferred embodiment of the present technical solution, the top ends of the two fixing bolts are fixedly connected with hook rings.

[0008] As a further preferred embodiment of the present technical solution, positioning sleeves are fixedly connected on both sides of the mounting plate, two positioning plates are fixedly connected to the inner side of the buffer plate, and outer surfaces of the two positioning plates are slidably connected to the inside of the two positioning sleeves respectively.

[0010] The utility model provides an anti-collision buffer structure for a mobile robot, which has the following beneficial effects:

[0011] (1) The utility model transmits the impact force to the elastic buffer rod through the process that the buffer plate slides when it is impacted. The elastic buffer rod is deformed under the action of the impact force and diffuses the received force to all sides along the outer surface of the elastic buffer rod, thereby dispersing the reaction force generated after the impact and reducing the direct reaction force on the robot body. When the elastic buffer rod reaches a certain deformation degree, the damper contracts due to the pressure and causes the buffer spring to follow the contraction and undergo elastic deformation, thereby performing secondary buffering, reducing the vibration of the internal components of the robot body during the impact and prolonging its service life.

[0012] (2) The utility model pulls up the fixing bolt, causing the elastic clamp head to shrink inward under tension, so that the fixing bolt can be directly withdrawn from the clamping seat and the mounting plate, thereby removing the restriction between the mounting plate and the clamping seat, facilitating rapid disassembly and replacement of the buffer assembly and improving maintenance efficiency.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figure 1-4 As shown, in the present embodiment, a collision prevention and buffering structure of a mobile robot includes a robot body 1, a mounting plate 2 is fixedly connected on all four sides of the robot body 1, a card holder 3 is inserted inside the mounting plate 2, a plurality of No. 1 connecting plates 4 are fixedly connected inside the card holder 3, a damper 5 is fixedly connected to one side of the plurality of No. 1 connecting plates 4, a buffer spring 6 is sleeved on the outer surface of the plurality of dampers 5, a No. 2 connecting plate 8 is fixedly connected to the other end of the plurality of dampers 5, a buffer plate 9 is fixedly connected to one side of the plurality of No. 2 connecting plates 8, two elastic buffer rods 7 are fixedly connected between two adjacent No. 1 connecting plates 4 and No. 2 connecting plates 8, wherein, by providing the mounting plate 2 for installation and fixation with the robot body 1, and by providing the damper 5, the speed of restoring elastic deformation between the buffer spring 6 and the elastic buffer rod 7 can be slowed down to prevent secondary impact on the robot body 1.

[0020] like Figure 3 and Figure 4 As shown, two clamping plates 13 are fixedly connected to one side of the mounting plate 2 and near the upper edge. Circular through holes 14 are penetrated at the top of the two clamping plates 13. Fixed through holes 16 are penetrated at the top of the holder 3 and located inside the two circular through holes 14. Fixing bolts 17 are inserted into the two circular through holes 14. The other ends of the two fixing bolts 17 are respectively inserted into the two fixing through holes 16. The bottom ends of the two fixing bolts 17 are fixedly connected to a plurality of elastic clamps 18. The outer surfaces of the plurality of elastic clamps 18 are clamped into the fixing through holes 16. The fixing bolts 17 are provided to limit the mounting plate 2 and the holder 3. The elastic clamps 18 are provided to facilitate disassembly and prevent the fixing bolts 17 from falling off.

[0021] like Figure 4 As shown, the top ends of the two fixing bolts 17 are fixedly connected with hook rings 15, which facilitates the removal of the fixing bolts 17 and improves the disassembly speed.

[0022] like Figure 2 and Figure 3 As shown, positioning sleeves 10 are fixedly connected on both sides of the mounting plate 2, and two positioning plates 11 are fixedly connected to the inner side of the buffer plate 9. The outer surfaces of the two positioning plates 11 are respectively slidably connected to the inside of the two positioning sleeves 10, so as to position the buffer plate 9 and prevent it from tilting during a collision and causing damage to components such as the damper 5.

[0024] The utility model provides an anti-collision buffer structure for a mobile robot, and the specific working principle is as follows:

[0025] When the robot body 1 collides with other objects during its movement, the buffer plate 9 transmits the impact force to the elastic buffer rod 7 during the process of sliding under the impact force. The elastic buffer rod 7 is deformed under the action of the impact force and diffuses the force received to all sides along the outer surface of the elastic buffer rod 7, thereby dispersing the reaction force generated after the collision and reducing the direct reaction force on the robot body 1. When the elastic buffer rod 7 reaches a certain degree of deformation, the damper 5 is compressed by the pressure and the buffer spring 6 is elastically deformed following the contraction to perform secondary buffering, thereby reducing the vibration of the internal components of the robot body 1 during the collision. When the components between the buffer plate 9 and the holder 3 need to be replaced after the collision, the staff pulls up the fixing bolt 17 in turn, so that the elastic clamp 18 is subjected to tension and shrinks inward, so that the fixing bolt 17 is directly pulled out from the holder 3 and the mounting plate 2, and the restriction between the mounting plate 2 and the holder 3 is released for disassembly and replacement.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
