Description

Technical Field

[0001] This utility model relates to the field of protection technology for inspection robots, and in particular to an anti-collision structure for inspection robots. Background Technology

[0002] Existing inspection robots have limited buffering effect when facing hard obstacles or high-speed moving scenes, which can easily lead to damage to the robot body, sensors or the equipment being collided with. The risk of collision is particularly high in scenarios with dense precision equipment, such as industrial workshops and substations.

[0003] However, when traditional AGVs are used to transport goods, the electromagnetically guided AGVs are guided by the strength of electromagnetic signals. Therefore, when traveling around corners, the center line of the AGV may deviate from the bottom cable. In some storage facilities with narrow bottom surfaces, this can easily cause the AGV to collide with the wall, which can easily lead to damage to the side wall of the AGV.

[0004] An existing patent (publication number: CN217801825U) discloses an anti-collision structure for an industrial robot. The AGV (Automated Guided Vehicle) body has four baffles around its perimeter. Two connecting blocks engage with each baffle, and buffer springs are fixedly connected to the connecting blocks. The buffer springs are fixedly connected to mounting plates, which are detachably connected to the AGV body via multiple bolts. Two locking blocks are slidably connected to the baffles, engaging with the connecting blocks. Pulling blocks are fixedly connected to the locking blocks. When the AGV collides with an object during its movement, the baffles will first contact the object. At this time, the multiple buffer springs will deform, reducing the impact force on the AGV and thus minimizing damage. Furthermore, if the baffles deform or are damaged during a collision, pulling the two pulling blocks will cause the locking blocks to move away from the connecting blocks. When neither locking block engages with the connecting blocks, the baffle can be removed, facilitating replacement and maintenance.

[0005] To address the aforementioned issues, existing patents offer solutions. However, the anti-collision structures used in existing inspection robots typically only provide initial weakening of the impact force in frontal collisions, failing to form a tiered protection system. When the robot encounters a strong frontal collision, the impact force acts directly on the anti-collision plate and is quickly transmitted to the robot body. This not only has limited buffering effect but also easily leads to deformation of the anti-collision plate and damage to transmission components due to localized stress concentration, which in turn causes failure of precision components such as sensors and controllers inside the robot. Furthermore, the side protection of existing inspection robots mostly adopts an integrated buffer structure, which can only buffer the impact force through the deformation of the baffle itself during a collision. It cannot achieve uniform transmission and gradual attenuation of the impact force, which can easily result in localized damage to the baffle while other areas fail to provide protection, leading to uneven stress on the robot's sidewalls and causing tilting.

[0006] To address this, a collision avoidance structure for inspection robots is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an anti-collision structure for inspection robots, which solves the problem that existing anti-collision structures for inspection robots typically only initially weaken the impact force in frontal collision protection and cannot form a graded protection system. When the robot encounters a strong frontal collision, the impact force acts directly on the anti-collision plate and is quickly transmitted to the robot body. Not only is the buffering effect limited, but it is also prone to deformation of the anti-collision plate and damage to transmission components due to local stress concentration, which in turn causes failure of precision components such as sensors and controllers inside the robot. Moreover, the side protection of existing inspection robots mostly adopts an integrated buffer structure, which can only buffer the impact force through the deformation of the baffle itself during a collision. It cannot achieve uniform transmission and gradual attenuation of the impact force, and it is easy for the baffle to be partially damaged while other areas fail to play a protective role, which leads to uneven stress on the robot's sidewalls and causes tilting.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance structure for an inspection robot, comprising an inspection robot body, an anti-collision component on the front side of the inspection robot body, and protective components on both sides of the inspection robot body.

[0009] Preferably, the protective component includes a mounting frame fixedly connected to the outside of the inspection robot body, and a connecting frame is movably connected to the front side of the mounting frame.

[0010] Preferably, both the mounting frame and the connecting frame have insertion holes inside, and a fixing rod is inserted into the insertion hole. The connecting frame has a limit groove inside.

The transmission connecting seat is fixedly connected to the anti-collision plate.

[0013] Preferably, a reset torsion spring is sleeved on the outer side of the rotating shaft, and the two sides of the reset torsion spring are fixedly connected to the outer sides of the two rotating rods.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 The present invention provides the following technical solution:

[0030] A collision avoidance structure for an inspection robot includes an inspection robot body 1, a collision avoidance component 2 on the front side of the inspection robot body 1, and protective components 3 on both sides of the inspection robot body 1. The collision avoidance component 2 includes a mounting plate 201 fixedly connected to the front side of the inspection robot body 1, a collision avoidance frame 202 fixedly connected to the front side of the mounting plate 201, a transmission plate 203 slidably connected to the front side of the collision avoidance frame 202, an arc-shaped bending plate 204 fixedly connected to the rear side of the transmission plate 203, and rigid springs 205 fixedly connected to both sides of the transmission plate 203. The side of the rigid springs 205 away from the transmission plate 203 is fixedly connected to the interior of the collision avoidance frame 202. A transmission rod 206 is fixedly connected to the front side of the transmission plate 203, and a collision avoidance plate 207 is fixedly connected to the side of the transmission rod 206 away from the transmission plate 203.

[0031] In this embodiment: when the inspection robot encounters a head-on collision during its movement, the rubber buffer pad 12 on the front side of the anti-collision plate 207 first contacts the obstacle, and the impact force is initially buffered through rubber deformation to prevent the anti-collision plate 207 from being directly hit hard. Then, the anti-collision plate 207 moves backward in a preset direction, and the limiting slider 11 fixed to the anti-collision plate 207 slides in the limiting slide rail 10 inside the limiting seat 9 to ensure that the movement trajectory of the anti-collision plate 207 is stable and does not deviate. While the anti-collision plate 207 moves, it drives the transmission... The moving connecting seat 7 pulls the rotating rod 6 to rotate around the rotating shaft 5 inside the rotating seat 4. The return torsion spring 8 outside the rotating shaft 5 is twisted and accumulates the return force. On the other hand, it drives the transmission rod 206 to push the transmission plate 203 to slide inside the anti-collision frame 202. The hard springs 205 on both sides of the transmission plate 203 are compressed and contracted. The spring deformation further absorbs the collision kinetic energy. The arc-shaped bending plate 204 on the rear side of the transmission plate 203 disperses the concentrated impact force to all sides by relying on the arc structure to prevent local stress concentration from causing damage to the components.

[0032] Specifically, such as Figure 4 As shown, the protective component 3 includes a mounting frame 301 fixedly connected to the outside of the inspection robot body 1, and a connecting frame 302 is movably connected to the front side of the mounting frame 301.

[0033] Specifically, such as Figure 4 As shown, both the mounting frame 301 and the connecting frame 302 have insertion holes inside, and a fixing rod 303 is inserted into the insertion hole. The connecting frame 302 has a limiting groove 304 inside.

[0034] Specifically, such as Figure 4 As shown, four compression springs 305 are fixedly connected inside the limiting groove 304, and a limiting block 306 is fixedly connected to the outside of the four compression springs 305. The outside of the limiting block 306 is slidably connected to the inside of the limiting groove 304, and a protective support plate 307 is fixedly connected to the outside of the limiting block 306.

[0035] In this embodiment: when the inspection robot encounters collisions on both sides during its movement, the protective support plate 307 first contacts the obstacle and transmits the impact force inward, causing the fixed limiting block 306 to slide within the limiting groove 304 inside the connecting frame 302. During the sliding process, the limiting block 306 compresses the compression spring 305 within the limiting groove 304 on one hand, and compresses the return spring 15 through the inner abutment block 14 on the other hand. The compression spring 305 and the return spring 15 together buffer part of the impact force through deformation, while the abutment block 14 simultaneously disperses the concentrated impact force to the surrounding area, preventing... In the event of a local overload, as the limit block 306 continues to slide, the side of it furthest from the protective support plate 307 abuts against the energy-absorbing box 13 inside the connecting frame 302. The energy-absorbing box 13 absorbs the remaining impact force through controllable deformation, further reducing the transmission of the impact force to the robot body. When maintenance or replacement of the protective component 3 is required, simply remove the fixing rod 303 to release the fixing between the mounting frame 301 and the connecting frame 302, disassemble the connecting frame 302 and its internal components for inspection, and reinsert the fixing rod 303 after maintenance to ensure that the protective component 3 quickly restores its protective function.

[0036] Specifically, such as Figure 2 , Figure 6 As shown, four rotating seats 4 are fixedly connected to the front side of the mounting plate 201. A rotating shaft 5 is rotatably connected to the inner side of the rotating seat 4. Rotating rods 6 are rotatably connected to both sides of the rotating shaft 5. A transmission connecting seat 7 is rotatably connected to the side of the rotating rod 6 away from the rotating shaft 5. The transmission connecting seat 7 is fixedly connected to the anti-collision plate 207.

[0037] Specifically, such as Figure 2 , Figure 6 As shown, a reset torsion spring 8 is sleeved on the outer side of the rotating shaft 5, and the two sides of the reset torsion spring 8 are fixedly connected to the outer sides of the two rotating rods 6.

[0038] In this embodiment: by setting up a rotating seat 4, a rotating shaft 5, a rotating rod 6, a transmission connecting seat 7, and a return torsion spring 8, when the inspection robot encounters a frontal collision, the anti-collision plate 207, after receiving the impact force, will synchronously drive the transmission connecting seat 7, which is fixed to it, to move backward. The transmission connecting seat 7 then pulls the rotating rod 6, which is rotatably connected to it, causing the rotating rod 6 to rotate around the rotating shaft 5, which is fixed to the front side of the rotating seat 4. The rotating shaft 5 remains stable under the limiting effect of the rotating seat 4, preventing the rotating rod 6 from deviating. The rotation process of the rotating rod 6 can help transmit the impact force on the anti-collision plate 207. The impact force is converted into the kinetic energy of rotation, preparing for subsequent energy absorption and component reset. At the same time, the reset torsion spring 8, which is sleeved on the outside of the rotating shaft 5, is twisted as the rotating rod 6 rotates. During the twisting process, the reset torsion spring 8 accumulates elastic reset force. When the collision ends and the impact force disappears, the reset torsion spring 8 releases the accumulated elastic force and pushes the rotating rods 6 on both sides back to the initial rotation position. The rotating rods 6 then drive the anti-collision plate 207 back to its original position through the transmission connecting seat 7, ensuring that the anti-collision component 2 can quickly return to the protected state after a single collision.

[0039] Specifically, such as Figure 6 As shown, a limiting seat 9 is fixedly connected to the outer side of the inspection robot body 1, a limiting slide rail 10 is fixedly connected to the inside of the limiting seat 9, a limiting slider 11 is slidably connected to the inner side of the limiting slide rail 10, and the side of the limiting slider 11 away from the limiting slide rail 10 is fixedly connected to the anti-collision plate 207.

[0040] Specifically, such as Figure 1 , Figure 2 As shown, a buffer pad 12 is fixedly connected to the front side of the anti-collision plate 207. The buffer pad 12 is made of rubber.

[0041] In this embodiment: by setting a limiting seat 9, a limiting slide rail 10, and a limiting slider 11, when a frontal collision occurs, the anti-collision plate 207 moves backward under the impact force. At this time, the limiting slider 11, which is fixed to the anti-collision plate 207, will slide synchronously within the limiting slide rail 10 inside the limiting seat 9 fixed on the outside of the inspection robot body 1. The limiting seat 9 provides fixed support for the limiting slide rail 10, and the limiting slide rail 10 restricts the movement trajectory of the anti-collision plate 207 through sliding cooperation with the limiting slider 11, preventing the anti-collision plate 207 from shifting left or right or tilting during movement, and ensuring that the anti-collision plate 207 can always be pushed and transmitted in the preset direction. The rod 206 and the transmission connecting seat 7 ensure the stability of the force transmission path of the anti-collision plate 207 and prevent the protective function from failing due to trajectory deviation. By setting the buffer pad 12, when the inspection robot comes into contact with an obstacle, the rubber buffer pad 12 fixed on the front side of the anti-collision plate 207 will first come into contact with the obstacle. The rubber material has good elasticity and will deform at the moment of contact. Through the deformation process, the impact force generated by the collision is initially absorbed and buffered, reducing the impact intensity directly acting on the anti-collision plate 207 and preventing the anti-collision plate 207 from being deformed or damaged due to direct hard impact. At the same time, it can also reduce the risk of the obstacle surface being damaged by collision.

[0042] Specifically, such as Figure 5 As shown, an energy-absorbing box 13 is fixedly connected inside the connecting frame 302, and the side of the energy-absorbing box 13 away from the connecting frame 302 is movably connected to the limiting block 306.

[0043] Specifically, such as Figure 5 As shown, an abutment block 14 is fixedly connected to the inner side of the protective support plate 307, and a return spring 15 is fixedly connected to the inner side of the abutment block 14.

[0044] In this embodiment: by setting up the energy-absorbing box 13, when the inspection robot encounters collisions on both sides, the protective support plate 307 will move inward after being impacted, causing the limiting block 306 fixed thereto to slide within the limiting groove 304 inside the connecting frame 302. As the limiting block 306 slides, the side away from the protective support plate 307 will gradually come into contact with the energy-absorbing box 13 fixed inside the connecting frame 302. The continuous impact force will cause the energy-absorbing box 13 to undergo controllable deformation. The energy-absorbing box 13 will absorb the residual force generated by the collision through its own deformation. It can be converted into structural deformation energy, further attenuating the impact force and effectively protecting the precision components inside the main body. By setting the abutment block 14, when the two sides of the inspection robot collide, the protective support plate 307 moves inward and simultaneously drives the abutment block 14 fixed on its inner side to move. The abutment block 14 then squeezes the reset spring 15 fixed to it. The reset spring 15 generates elastic force through deformation, which helps to buffer part of the collision impact force. After the collision ends, the compressed reset spring 15 drives the abutment block 14 and the protective support plate 307 to reset.

[0045] Working principle: When the inspection robot is working, if the main body 1 of the inspection robot encounters a frontal collision during its movement, the rubber buffer pad 12 on the front side of its anti-collision plate 207 will first come into contact with the obstacle. The elastic deformation of the rubber itself will initially buffer the impact force, preventing the anti-collision plate 207 from being damaged by direct hard impact. Then, the anti-collision plate 207 will simultaneously drive the transmission rod 206 and the transmission connecting seat 7 to move backward. The transmission connecting seat 7 will then pull the rotating rod 6 to rotate around the rotating shaft 5 inside the rotating seat 4. The reset torsion spring 8 mounted on the outside of the rotating shaft 5 will be twisted under the action of the rotating rod 6, and at the same time accumulate reset force. Meanwhile, the transmission rod 206 will push the transmission plate 203 to slide smoothly in a preset direction inside the anti-collision frame 202. The rigid springs 205 connected to both sides of the transmission plate 203 are compressed by the transmission plate 203, further absorbing the kinetic energy generated by the collision through spring deformation. Furthermore, the arc-shaped bending plate 204 on the rear side of the transmission plate 203, relying on its own arc structure, disperses the concentrated impact force in all directions, effectively preventing damage to components due to localized stress concentration. During this process, the anti-collision plate 207 slides within the limiting slide rail 10 inside the limiting seat 9 on the outer side of the inspection robot body 1 via its connected limiting slider 11. The cooperation between the limiting slide rail 10 and the limiting slider 11 ensures the stability of the movement trajectory of the anti-collision plate 207 and related components, preventing the protective function from failing due to deviation. When a collision occurs on either side of the inspection robot body 1, the protective components 3 on both sides activate protection. The support plate 307 first contacts the obstacle. The impact force pushes the protective support plate 307 inward. The protective support plate 307 drives the limiting block 306 connected to it to slide within the limiting groove 304 inside the connecting frame 302. During the sliding process, the limiting block 306 compresses the compression spring 305 connected within the limiting groove 304 and the return spring 15 connected to the inner abutment block 14 of the protective support plate 307. The elastic deformation of the compression spring 305 and the return spring 15 together buffer part of the impact force. At the same time, after sliding to a certain position, the limiting block 306 abuts against the energy-absorbing box 13 fixed inside the connecting frame 302. The energy-absorbing box 13 absorbs the remaining impact energy through its own controllable plastic deformation, further reducing the impact force on the inspection machine. The robot body 1 transmits the pressure, while the contact block 14 assists in dispersing the pressure transmitted by the limiting block 306 to the surrounding area, ensuring that the force on each part of the protective component 3 is balanced and avoiding local overload damage. After the collision, the compressed spring 305 and the return spring 15 release the elastic force accumulated during the collision, causing the protective support plate 307 to return to its initial working position. When maintenance or replacement of the protective component 3 is required, first, move the fixed insertion rod 303 to release the fixing of the mounting frame 301 and the connecting frame 302, and then perform maintenance or replacement of the connecting frame 302 and the protective support plate 307. After maintenance or replacement is completed, realign the connecting frame 302 with the mounting frame 301, and then reinsert the fixed insertion rod 303.By securing the connecting frame 302 and the mounting frame 301 for maintenance, the anti-collision structure can continuously provide collision protection for the subsequent movement of the inspection robot, ensuring the safety of the main body 1 of the inspection robot and related precision components.
