[0028] The present utility model provides an anti-collision protection device 100.

[0029] Please refer to Figures 1-4 , in an embodiment of the present utility model, the anti-collision protection device 100 is used for a robot 200. The robot 200 has a robot body 20. The anti-collision protection device 100 includes: a fixed frame 1, a fixing plate 2, and a connecting component 3. The fixed frame 1 has an opening facing one side, and a first connection end 11 and a first fixed end 12 located on both sides of the opening. The fixing plate 2 is disposed on the opening side of the fixed frame 1. The fixing plate 2 has a second connection end 21 detachably connected to the first connection end 11 and a second fixed end 22 fixedly connected to the first fixed end 12. The fixing plate 2 and the fixed frame 1 enclose a frame body for surrounding the outer periphery of the robot body 20. An anti-collision structure 5 is provided on the outer peripheral surface of the frame body. The connecting component 3 is used to connect the first connection end 11 and the second connection end 21 and can disconnect the connection between the first connection end 11 and the second connection end 21 under the action of an external force.

[0030] In this embodiment, the fixed frame 1 can be formed by integral molding or by splicing to form a square structure surrounded on three sides. The fixed plate 2 serves as the fourth side of the square structure and forms a rectangular frame with the fixed frame 1 to enclose the robot body 20 and surround the outermost part of the outer contour of the robot body 20. When the robot 200 touches an obstacle such as a wall, it can preferentially impact the anti-collision protection device 100. The outer peripheral surface of the frame body is also provided with an anti-collision structure 5, which can buffer the impact force of the robot 200, thereby protecting the frame body and the robot body 20. The first fixed end 12 and the second fixed end 22 are fixedly connected, and the first connection end 11 and the second connection end 21 are detachably connected, so that the contour size of the frame body can be adjusted. As long as the distance between the first connection end 11 and the second connection end 21 is adjusted, the contour size of the frame body can be enlarged or reduced, so that the frame body can be enlarged first to enable the robot 200 to pass through and be sleeved around the robot body 20, and then the frame body is tightened and connected after reaching the installation position to fix the anti-collision protection device 100 around the robot body 20. The connection assembly 3 is used to connect or disconnect the first connection end 11 and the second connection end 21. When installing the device, the operator only needs to dock the first connection end 11 and the second connection end 21, and the self-limiting property of the internal structure of the connection assembly 3 can connect and limit the first connection end 11 and the second connection end 21; when removing the device, the operator only needs to press the connection assembly 3 to apply an external force to the connection assembly 3, and the first connection end 11 and the second connection end 21 can be disconnected to remove the anti-collision protection device 100.

[0031] The technical solution of the present utility model is to set a fixed frame 1 and a fixed plate 2 in the anti-collision protection device 100, set an opening in the fixed frame 1, and arrange the fixed plate 2 at the opening so that the fixed frame 1 and the fixed plate 2 can enclose to form a frame body that can be sleeved on the robot body 20; by setting a first fixed end 12 and a first connection end 11 in the fixed frame 1, setting a second fixed end 22 and a second connection end 21 in the fixed plate 2, the first fixed end 12 and the second fixed end 22 are fixedly connected, and the first connection end 11 and the second connection end 21 are detachably connected, so that the outer contour structure of the frame body can be adjusted to successfully surround the robot body 20; by adopting the connection assembly 3, the connection assembly 3 is used to connect the first connection end 11 and the second connection end 21 and can disconnect the connection between the first connection end and the second connection end 21 under the action of an external force. The operator only needs to dock the first connection end 11 and the second connection end 21 to connect them, and only needs to apply an external force to press the connection assembly 3 to disconnect it, thereby simplifying the disassembly and assembly steps of the anti-collision protection, enabling the operator to quickly disassemble and assemble the anti-collision protection device 100 from the robot 200 according to needs, and improving the disassembly and assembly efficiency of the anti-collision protection device 100.

[0032] Refer to Figure 2 、 4, in one embodiment, the fixed frame 1 includes a middle plate 13, and a first side plate 14 and a second side plate 15 fixedly connected to both ends of the middle plate 13. The first side plate 14 and the second side plate 15 are spaced apart from each other at the ends away from the middle plate 13 to form an opening; the connection assembly 3 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is disposed at the first connection end 11, and the first connecting member 31 can drive the first connection end 11 and the second connection end 21 to disconnect under an external force; the second connecting member 32 is disposed at the second connection end 21, and the second connecting member 32 can connect the first connection end 11 and the second connection end 21. In this embodiment, the first side plate 14 and the second side plate 15 are parallel and spaced apart at both ends of the middle plate 13 and are perpendicular to the middle plate 13, so that the fixed frame 1 forms a structure surrounded by three sides and open on one side to form an opening capable of accommodating the fixed plate 2. The connection assembly 3 includes a first connecting member 31 and a second connecting member 32. When the first connection end 11 is connected to the second connection end 21, the first connecting member 31 and the second connecting member 32 are spaced apart from each other and cannot touch each other. When it is necessary to disconnect the first connection end 11 and the second connection end 21, an external pressing force is applied to the first connecting member 31 towards the second connecting member 32, and the first connecting member 31 is pressed towards the second connecting member 32, and the first connection end 11 and the second connection end 21 can be disconnected.

[0033] Refer to Figure 2 , 3, in one embodiment, the first connection end 11 has a through hole formed along the thickness direction of the first side plate 14, and the first connecting member 31 is slidably disposed in the through hole; the through hole has a first cavity 111, a second cavity 112, and a third cavity 113 that are sequentially arranged and communicated with each other from the outer wall surface to the inner wall surface of the first side plate 14. The first connecting member 31 has a pressing portion 311, a reset portion 312, and a pushing portion 313 that are sequentially arranged. The pressing portion 311 is disposed in the first cavity 111, the reset portion 312 is disposed in the second cavity 112, and the pushing portion 313 is disposed in the third cavity 113; a first elastic member 314 is provided on one side of the reset portion 312 close to the third cavity 113, and the first elastic member 314 is used to drive the reset portion 312 to move toward the first cavity 111. The through hole is used to limit the movement trajectory of the first connecting member 31, and the first connecting member 31 can only move along the axial direction of the through hole without deflecting to other directions. The pressing portion 311 is used for an operator to apply an external force to the first connecting member 31 so as to apply an external force to the connecting assembly 3. A part of the pressing portion 311 protrudes from the outer wall surface of the first connection end 11 to provide a force application point for the operator; the reset portion 312 is used to reset the first connecting member 31 after the first connecting member 31 is pressed, so as to avoid the situation that the first connecting member 31 sinks into the through hole and cannot be used again after the operator applies a force to the first connecting member 31; the pushing portion 313 is used to act on the second connecting member 32 under an external force so as to disconnect the second connection end 21 from the first connection end 11. A first elastic member 314 is provided on one side of the reset portion 312 close to the third cavity 113, and the first elastic member 314 is used to reset the first connecting member 31. When it is necessary to disconnect the first connection end 11 from the second connection end 21, the operator needs to apply an external force to the first connecting member 31 in the direction close to the third cavity 113, and the reset member applies a force to the first connecting member 31 in the direction away from the third cavity 113 after the external force disappears, so as to push the pressing portion 311 out of the through hole again.

[0034] In one embodiment, the inner diameter of the first chamber 111 is smaller than that of the second chamber 112, so that a first limiting step is formed at the junction of the first chamber 111 and the second chamber 112, and the first limiting step abuts against the reset portion 312; the inner diameter of the third chamber 113 is smaller than that of the second chamber 112, so that a second limiting step is formed at the junction of the third chamber 113 and the second chamber 112, and the second limiting step abuts against the first elastic member 314. The inner diameter of the first chamber 111 is slightly larger than the outer diameter of the pressing portion 311, so that the pressing portion 311 can smoothly slide within the first chamber 111; the inner diameter of the second chamber 112 is slightly larger than the outer diameter of the reset portion 312 and larger than the inner diameter of the first chamber 111, so as to form a limiting step at the junction with the first chamber 111. At the same time, the outer diameter of the reset portion 312 is larger than the inner diameter of the first chamber 111 to limit the reset portion 312 from entering the first chamber 111; the inner diameter of the third chamber 113 is slightly larger than the outer diameter of the pushing portion 313 and smaller than the inner diameter of the second chamber 112, so as to form a limiting step at the junction with the second chamber 112. At the same time, the outer diameter of the reset portion 312 is larger than the inner diameter of the third chamber 113 to limit the reset portion 312 from entering the third chamber 113, and finally the reset portion 312 is completely restricted within the second chamber 112.

[0035] In one embodiment, a limiting groove 211 is formed on the end face of the second connection end 21. The second connecting member 32 is slidably disposed in the limiting groove 211. The limiting groove 211 has an opening facing the first connection end 11. A limiting portion 212 is provided at the opening of the limiting groove 211, and a limiting hole is formed in the limiting portion 212. The second connecting member 32 includes a clamping block 321 and a limiting block 322. The clamping block 321 is disposed on one side of the limiting block 322 close to the limiting portion 212. The limiting block 322 is disposed in the limiting groove 211. The clamping block 321 passes through the limiting hole. A second elastic member 323 is provided on the side of the limiting block 322 away from the clamping block 321. The second elastic member 323 is used to drive the limiting block 322 to move toward the limiting portion 212. When the first connection end 11 is connected to the second connection end 21, the limiting groove 211 communicates with the third cavity 113. The clamping block 321 can pass through the limiting hole and be disposed in the third cavity 113. The first connecting member 31 can move toward the second connecting member 32 under an external force to drive the pushing portion 313 to push the clamping block 321 out of the third cavity 113. The limiting groove 211 is used to limit the movement track of the second connecting member 32. The second connecting member 32 can only move along the axial direction of the limiting groove 211 in the limiting groove 211 without deviating from the movement track. The limiting portion 212 is provided at the opening of the limiting groove 211 and extends radially inward from the edge of the opening of the limiting groove 211. The limiting portion 212 is used to limit the movement track of the second connecting member 32 to prevent the second connecting member 32 from disengaging from the limiting groove 211. A limiting hole is formed in the middle of the limiting portion 212 for the second connecting member 32 to pass through to cooperate with the first connecting member 31. The limiting block 322 and the clamping block 321 are integrally provided. The outer diameter of the limiting block 322 is slightly smaller than the inner diameter of the limiting groove 211 and larger than the inner diameter of the limiting hole, so that it can slide axially in the limiting groove 211 without disengaging. The outer diameter of the clamping block 321 is slightly smaller than the limiting hole to slide in the limiting hole. An elastic member is provided at one end of the limiting block 322 away from the clamping block 321. The elastic member is used to reset the limiting block 322. When the second connecting member 32 moves toward the elastic member under an external force, the elastic member can push the second connecting member 32 back to its original position to connect the first connection end 11 and the second connection end 21.

[0036] In one embodiment, an installation groove is formed on the outer side wall of the fixed frame 1 and / or the outer side wall of the fixed plate 2. The anti-collision structure 5 is disposed in the installation groove. The installation groove is used to install the anti-collision structure 5. The depth of the installation groove is the same as that of the anti-collision structure 5, so that when the anti-collision structure 5 is installed in the installation groove, the outer wall surface of the frame body is still flush, which not only does not affect the anti-collision structure 5 from playing a role, but also can reduce the damage to the anti-collision structure 5, and can also make the outer surface of the anti-collision protection device 100 more beautiful.

[0037] In one embodiment, the anti-collision structure 5 includes: an anti-collision block 51, a mounting strip 52, a distance sensing strip 53, and a buffer strip 54; the anti-collision block 51 is fixedly installed in the installation groove, and a reserved groove is formed on one side of the anti-collision block 51 facing away from the bottom of the installation groove; the mounting strip 52 is fixedly installed in the reserved groove; the distance sensing strip 53 is fixedly connected to one side of the mounting strip 52 facing away from the anti-collision block 51; the buffer strip 54 is arranged between the outer side wall of the anti-collision block 51 and the inner side wall of the installation groove. The anti-collision block 51 is used to provide an installation position for the mounting strip 52. A groove is formed on the outer side of the anti-collision block 51, and the mounting strip 52 is arranged in the groove. The mounting strip 52 is used to install the distance sensing strip 53, so that the distance sensing strip 53 can be fixed on the anti-collision block 51 and can also protect the internal distance sensing strip 53. The distance sensing strip 53 is arranged in the mounting strip 52 and is used to sense the distance between the robot body 20 and the obstacle, and make the robot 200 react through an electrical signal; the buffer strip 54 is arranged in the gap between the anti-collision block 51 and the inner wall of the installation groove to fill the gap of the inner wall of the installation groove, damp the anti-collision block 51 and the components installed inside the anti-collision block 51, buffer the impact force received, and extend the service life of the frame and the anti-collision structure 5.

[0038] In one embodiment, an anti-collision strip 6 is further provided on the periphery of the fixed frame 1. The anti-collision strip 6 is arranged at the first connection end 11; and / or, the anti-collision strip 6 is arranged at the first fixed end 12; and / or, the anti-collision strip 6 is arranged at the connection between the first side plate 14 and the middle plate 13; and / or, the anti-collision strip 6 is arranged at the connection between the second side plate 15 and the middle plate 13. In this embodiment, the anti-collision strips 6 are arranged at the four corners of the rectangular frame. Since the four corners of the frame are more likely to be damaged due to stress concentration, adding the anti-collision strips 6 to buffer the impact force received can extend the service life of the anti-collision protection device 100. The anti-collision strips 6 can be made of materials with good flexibility such as silicone or rubber, which can better buffer the impact force and are also convenient for frequent replacement.

[0039] In one embodiment, the anti-collision protection device 100 further includes an anti-slip sheet 7, and the anti-slip sheet 7 is attached to the inner side wall of the frame. The anti-slip sheet 7 is made of materials such as rubber and is used to increase the friction force on the inner wall of the protection device, so that when the frame is sleeved around the robot body 20, it is not easy to slip off, avoiding the situation where the device slips off and cannot protect the robot body 20.

[0040] Refer to Figure 5, the present utility model further provides a robot 200, which includes a robot body 20 and any one of the above anti-collision protection devices 100. The specific structure of the anti-collision protection device 100 refers to the above embodiments. Since the robot 200 adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, a relatively shallow installation groove can be opened on the periphery of the robot body 20, and the depth of the installation groove is less than the thickness of the anti-collision protection device 100, so that the anti-collision protection device 100 can always protrude from the outer peripheral wall of the robot body 20 to achieve the purpose of protecting the robot body 20. A boss can also be provided below the installation position of the anti-collision protection device 100, and the height of the boss is less than the thickness of the frame to prevent the anti-collision protection device 100 from falling off.
