Robotic flexible crashworthy enclosure

Abstract

This utility model belongs to the field of robotics technology and discloses a flexible anti-collision shell for robots. It includes a shell body, with fixed posts fixedly installed on the front and rear sides of the four corners of the shell body. A circular block is movably fitted onto the outward-facing side of the interior of each fixed post, and an extension post is fixedly installed on the outward-facing side of the outer surface of the circular block. This utility model, by setting up an anti-collision plate, an inclined plate, a rectangular block, a circular rod, and a first spring, allows the inclined plate, hinged to the anti-collision plate, to move along with the anti-collision plate when it is impacted. This causes the other end of the inclined plate to exert a pushing force on the rectangular block, pushing the rectangular block along the outer surface of the circular rod and compressing the first spring. Under the restoring action of the first spring, the rectangular block, along with the inclined plate and the anti-collision plate, is forced to return to its original position. Thus, flexible anti-collision is achieved through the cooperation of the anti-collision plate, the inclined plate, the rectangular block, and the first spring, thereby protecting the robot shell.

Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, specifically a flexible anti-collision shell for robots. Background Technology

[0002] A robot is an intelligent machine system capable of automatically performing tasks. It typically combines technologies from multiple fields such as mechanical engineering, electronics, computer science, and artificial intelligence. It mainly consists of a mechanical structure, including the body, joints, and sensors; a control system, which controls behavior through algorithms and programs, and is divided into preset instructions and autonomous decision-making; a perception system, which uses cameras, lidar, tactile sensors, etc. to collect environmental data; and a power system.

[0003] A search revealed a robot shell with announcement number CN211630619U. This design addresses the need for routine maintenance of robots during operation, requiring the shell to be opened for inspection and replacement of internal structures and electrical components. Existing designs are typically integrated or complex, hindering quick routine maintenance. The proposed solution involves left and right hatches with locks, allowing access via a key to either the top access port or the left and right hatches for inspection and replacement of internal components. This design is simple, easy to operate, and allows for quick access to different parts of the robot for maintenance. However, in practical use, it has shortcomings. Although obstacle avoidance is implemented, collisions with hard objects still occur. Since the shell lacks flexible anti-collision components, repeated impacts can easily damage the shell, potentially exposing internal components. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a flexible anti-collision shell for robots, which has the advantage of achieving flexible anti-collision.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible anti-collision shell for a robot, comprising a shell body, with fixed posts fixedly installed on the front and rear sides of the four corners of the shell body, a circular block movably sleeved on the outward side of the inside of the fixed post, an extension post fixedly installed on the outward side of the outer surface of the circular block, the other end of the extension post penetrating the fixed post and extending to the outside of the fixed post and fixedly installed with an anti-collision plate, an inclined plate hinged to the middle of the outer surface of the anti-collision plate facing the shell body, a rectangular block hinged to the other end of the inclined plate, a back plate movably connected to the outer surface of the rectangular block facing the shell body, the outer surface of the back plate being fixedly connected to the outer surface of the shell body, adjusting rods movably connected to the front and rear sides of the outward side of the outer surface of the back plate, a circular rod movably sleeved inside the adjusting rod, the outer surface of the circular rod being movably sleeved to the inner surface of the rectangular block, a first spring fixedly installed on the outer surface of the adjusting rod facing the rectangular block, the other end of the first spring being fixedly connected to the outer surface of the rectangular block.

[0006] As a preferred embodiment of this utility model, the upper and lower ends of the rectangular block are respectively movably fitted with limit rods, the outer surface of the limit rods and the inner surface of the adjusting rods are movably fitted together, and rubber pads are respectively fixedly installed at the front and rear ends of the outer surface of the anti-collision plate facing the main body of the outer shell.

[0007] As a preferred embodiment of this utility model, a fixing frame is fixedly installed at both the front and rear ends of the outer surface of the back plate facing outward. The outer surface of the fixing frame is movably connected to the outer surface of the adjusting rod. The outer surface of the fixing frame is fixedly connected to the outer surfaces of the round rod and the limiting rod. A crossbar is fixedly installed at the top of the fixing frame. The bottom end of the crossbar is movably connected to the top end of the adjusting rod.

[0008] As a preferred embodiment of this utility model, a limiting groove is provided at the bottom end of the crossbar, and limiting blocks are movably sleeved at the front and rear ends of the limiting groove, with the bottom end of the limiting block and the top end of the adjusting rod being fixedly connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a collision avoidance plate, an inclined plate, a rectangular block, a round rod, and a first spring. When the collision avoidance plate is impacted, the inclined plate, which is hinged to the collision avoidance plate, will move along with it.

Under the restoring action of the first spring, the rectangular block, along with the inclined plate and the collision avoidance plate, will be forced to return to its original position. In this way, flexible collision avoidance can be achieved through the cooperation of the collision avoidance plate, the inclined plate, the rectangular block, and the first spring, thereby protecting the robot's shell.

[0021] 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.

[0022] like Figures 1 to 6 As shown, this utility model provides a flexible anti-collision shell for a robot, including a shell body 1. Fixed posts 2 are fixedly installed on the front and rear sides of the four corners of the shell body 1. A circular block 3 is movably sleeved on the outward side of the interior of the fixed post 2. An extension post 4 is fixedly installed on the outward side of the outer surface of the circular block 3. The other end of the extension post 4 passes through the fixed post 2 and extends to the outside of the fixed post 2, where an anti-collision plate 5 is fixedly installed. A sloping plate 6 is hinged to the middle of the outer surface of the anti-collision plate 5 facing the shell body 1. A rectangular block 7 is hinged to the other end of the sloping plate 6. A back plate 8 is movably connected to the outer surface of the rectangular block 7 facing the shell body 1. The outer surface of the back plate 8 is fixedly connected to the outer surface of the shell body 1. Adjusting rods 9 are movably connected to the front and rear sides of the outward side of the outer surface of the back plate 8. A circular rod 10 is movably sleeved inside the adjusting rod 9. The outer surface of the circular rod 10 and the inner surface of the rectangular block 7 are movably sleeved on the inner surface of the rectangular block 7. The surface is movable. A first spring 11 is fixedly installed on the outer surface of the adjusting rod 9 facing the rectangular block 7. The other end of the first spring 11 is fixedly connected to the outer surface of the rectangular block 7. When a collision occurs, the anti-collision plate 5, along with the extension post 4 and the round block 3, will move along the inner surface of the fixed post 2. At the same time, since the two ends of the inclined plate 6 are hinged to the anti-collision plate 5 and the rectangular block 7 respectively, as the anti-collision plate 5 moves, one end of the inclined plate 6 will move along with it. This will cause the other end of the inclined plate 6 to exert a pushing force on the rectangular block 7, pushing the rectangular block 7 to move along the outer surface of the round rod 10 and compress the first spring 11. Under the restoring action of the first spring 11, the rectangular block 7, along with the inclined plate 6 and the anti-collision plate 5, will be forced to return to its original position. This achieves flexible anti-collision and protects the robot shell.

[0023] Among them, the upper and lower ends of the rectangular block 7 are respectively movably fitted with limit rods 12, the outer surface of the limit rods 12 and the inner surface of the adjusting rods 9 are movably fitted, and the front and rear ends of the outer surface of the anti-collision plate 5 facing the outer shell body 1 are respectively fixedly installed with rubber pads 13. The presence of the limit rods 12 will assist in limiting the rectangular block 7 and the adjusting rods 9, thereby ensuring the stability of the movement of the rectangular block 7 and the adjusting rods 9, while the presence of the rubber pads 13 will play an auxiliary buffering role in the event of a collision.

[0024] The back plate 8 has a fixed bracket 14 fixedly installed at both ends of the outer side facing outward. The outer surface of the fixed bracket 14 is movably connected to the outer surface of the adjusting rod 9. The outer surface of the fixed bracket 14 is also fixedly connected to the outer surfaces of the round rod 10 and the limiting rod 12. A crossbar 15 is fixedly installed at the top of the fixed bracket 14. The bottom end of the crossbar 15 is movably connected to the top end of the adjusting rod 9. The fixed bracket 14 will support and fix the round rod 10 and the limiting rod 12. The crossbar 15 is used to connect the fixed brackets 14 at both ends of the back plate 8, thereby improving the stability of the fixed bracket 14.

[0025] The bottom end of the crossbar 15 has a limiting groove 16, and the front and rear ends of the limiting groove 16 are respectively movably sleeved with limiting blocks 17. The bottom end of the limiting block 17 is fixedly connected to the top end of the adjusting rod 9. The inner surface of the limiting groove 16 and the outer surface of the limiting block 17 are both smooth, so as to ensure that the limiting block 17 will not get stuck when it moves along the inner surface of the limiting groove 16. At the same time, the cooperation between the limiting groove 16 and the limiting block 17 can further restrict the movement of the adjusting rod 9.

[0026] The limiting block 17 has a double threaded rod 18 threaded inside its middle end. The front and rear ends of the double threaded rod 18 pass through the crossbar 15 and extend to the outside of the crossbar 15, and are fixedly sleeved with handles 19. The outer surface of the handles 19 is movably connected to the outer surface of the crossbar 15. When the handles 19 are rotated, the double threaded rod 18 will rotate along the inner surface of the crossbar 15. Since the outer surface of the double threaded rod 18 is threaded to the inner surface of the limiting block 17, the limiting block 17 will move along with the adjusting rod 9 under the action of the double threaded rod 18.

[0027] Among them, the front and rear ends of the main body 1 are respectively hinged with hatches 20, and the top of the outer surface of the hatches 20 facing outward is fixedly fitted with a lock 21. The presence of the hatches 20 makes it convenient to open the robot shell from the side for inspection and maintenance, while the presence of the lock 21 can lock the position of the hatches 20, thereby preventing the hatches 20 from being opened accidentally.

[0028] The top of the outer shell 1 is fixedly fitted with a first top cover 22, and the top of the first top cover 22 is fixedly fitted with a second top cover 23. The presence of the first top cover 22 and the second top cover 23 will make it easier for operators to open the outer shell from the top of the robot for maintenance, thereby improving the convenience of robot maintenance.

[0029] Working principle and usage process of this utility model:

[0030] When the robot collides, the anti-collision plate 5 is located on the periphery of the outer shell 1, so the anti-collision plate 5 will be the first to be impacted. At this time, the anti-collision plate 5 will move along the inner surface of the fixed column 2 with the circular block 3 through the extension column 4. At the same time, the anti-collision plate 5 will also move along one end of the inclined plate 6, so that the other end of the inclined plate 6 will generate a pushing force on the rectangular block 7, pushing the rectangular block 7 to move along the outer surface of the circular rod 10 and compress the first spring 11. Under the restoring action of the first spring 11, it will be forced to return to its original position, thus achieving flexible anti-collision and effectively protecting the robot shell.

[0031] When the handle 19 is turned, the double threaded rod 18 will rotate, causing the limiting block 17, which is threaded onto the outer surface of the double threaded rod 18, to move along the inner surface of the limiting groove 16 toward the rectangular block 7 with the adjusting rod 9, thereby compressing the first spring 11 and increasing the elastic force of the first spring 11. By adjusting the elastic force of the first spring 11, the strength of the anti-collision plate 5 to withstand impact can be improved, thereby further improving the flexible anti-collision effect.
