Description

Technical Field

[0001] The utility model relates to the technical field of patrol robots, in particular to a collision avoidance barrier applied to patrol robots. Background Art

[0002] Inspection robots are automated devices that replace or assist humans in performing regular inspection and monitoring tasks. Such robots are widely used in various industries and scenarios to improve efficiency, reduce costs, enhance safety, and ensure continuity and accuracy of operations.

[0003] The patent with the announcement number CN219115314U discloses a patrol robot, including: a main body, a bottom shell with an upper cavity arranged under the main body, a chassis arranged under the bottom shell, two rear wheels with a first rotating shaft arranged on the inner side of both sides of the chassis, two front wheels with a second rotating shaft arranged on the inner side of both sides of the chassis, a controller and a battery fixed in the upper cavity, a drive assembly arranged on the chassis, a steering assembly arranged between the two front wheels to control the rotation of the two front wheels, the controller is electrically connected to the drive assembly and the steering assembly respectively, and the controller controls the drive assembly and the steering assembly to work. This patrol robot does not need to install a steering motor and a drive motor on each wheel as in the prior art, so it has the advantages of simple structure, simple process, small size, high assembly efficiency, power saving, low cost and good stability.

[0004] However, the following problems still exist in the current inspection robots:

[0005] Although the inspection robot has an obstacle avoidance function, it is only used to avoid fixed obstacles or some slow-moving obstacles. When encountering some fast-moving obstacles, the inspection robot often cannot detect and make emergency avoidance before the collision, which may cause the inspection robot's appearance to be damaged after the collision, or even cause damage to the inspection robot's internal components. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a crash barrier for an inspection robot. When the robot body is suddenly collided with some fast-moving objects, the impact force brought by the object can be buffered by four crash bars cooperating with four buffer components, thereby reducing the probability of damage to components inside the robot body.

[0007] The utility model provides the following technical solutions: a crash barrier for an inspection robot, comprising a mounting plate installed on the bottom surface of a robot body, a fixed block fixedly connected to the other side of the mounting plate, four side walls of the fixed block connected to buffer components, the other ends of the four buffer components connected to support frames, the other ends of the four support frames fixedly connected to support plates, the other sides of the four support plates fixedly connected to crash bars at the same time, four auxiliary support components connected to one side of the mounting plate close to the fixed block, and the four auxiliary components connected to the four buffer components, respectively.

[0008] Furthermore, the buffer assembly includes an outer rod, an inner rod and a buffer spring. A spring cavity is formed through the inner wall of the outer rod. One end of the buffer spring and the outer rod are fixedly connected to the side wall of the fixed block. One end of the buffer spring away from the fixed block is fixedly connected to one end of the inner rod. The buffer spring and the inner rod are both located in the spring cavity, and the outer wall of the inner rod is slidably connected to the inner wall of the spring cavity. The other end of the inner rod is fixedly connected to a side of the support frame away from the support plate, and one end of the auxiliary support assembly away from the mounting plate is connected to the outer rod.

[0009] Furthermore, the auxiliary support assembly includes a limit block and a retaining ring. The upper surface of the limit block is fixedly connected to one side of the mounting plate close to the fixed block. The limit block is hinged to one side of the retaining ring. The limit block and the other side of the retaining ring are fastened together by bolts. The outer wall of the outer rod abuts against the inner wall of the limit block and the retaining ring.

[0010] Furthermore, a plurality of slide grooves are provided on the inner wall of the spring cavity, a plurality of sliders are fixedly connected to the outer wall of one end of the inner rod located in the spring cavity, and the outer walls of the plurality of sliders are slidably connected to the inner walls of the plurality of slide grooves respectively.

[0011] Furthermore, the four support frames are all arranged in multiple layers, and anti-collision rods are fixedly connected between the four support frames on the same layer.

[0012] Further, the anti-collision bar is in the form of a tubular airbag.

[0013] Furthermore, the mounting plate is fastened to the bottom surface of the robot body by bolts.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] This anti-collision barrier used for inspection robots is achieved by arranging a mounting plate and a fixed block on the bottom surface of the robot body, connecting four buffer components, a support frame and a support plate through the fixed block, and finally arranging an anti-collision bar surrounding the robot body between the four support plates. When the robot body is suddenly collided with some fast-moving objects, the four anti-collision bars can cooperate with four buffer components to buffer the impact force brought by the objects, thereby reducing the probability of damage to the internal components of the robot body.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4 A crash barrier for an inspection robot comprises a mounting plate 5 mounted on the bottom surface of a robot body 1, a fixing block 6 being fixedly connected to the other side of the mounting plate 5, four side walls of the fixing block 6 being connected to buffer components, the other ends of the four buffer components being connected to a support frame 2, the other ends of the four support frames 2 being fixedly connected to a support plate 3, the other sides of the four support plates 3 being fixedly connected to a crash barrier 4 at the same time, four auxiliary support components being connected to one side of the mounting plate 5 close to the fixing block 6, and the four auxiliary components being connected to the four buffer components respectively.

[0023] The anti-collision fence used in the inspection robot in the utility model is similar to the structure of the existing inspection robot, such as the inspection robot disclosed in the patent with publication number CN219115314U. Figures 1 to 4 As shown, when the anti-collision bar used in the inspection robot in the utility model is performing the inspection task normally, if it is suddenly hit by some fast-moving objects, the objects will hit the anti-collision bars 4 located around the robot body 1, and the anti-collision bars 4 will transmit the shock force to the support plate 3 after being impacted, and the support plate 3 will transmit the shock force to the support frame 2, and then transmit it to the buffer component, thereby reducing the direct impact force on the internal components of the robot body 1, thereby reducing the probability of damage to the robot body 1.

[0024] Please refer to Figure 4 The buffer assembly includes an outer rod 7, an inner rod 10 and a buffer spring 12. A spring cavity 701 is formed through the inner wall of the outer rod 7. One end of the buffer spring 12 and the outer rod 7 are fixedly connected to the side wall of the fixed block 6. The end of the buffer spring 12 away from the fixed block 6 is fixedly connected to one end of the inner rod 10. The buffer spring 12 and the inner rod 10 are both located in the spring cavity 701, and the outer wall of the inner rod 10 is slidably connected to the inner wall of the spring cavity 701. The other end of the inner rod 10 is fixedly connected to a side of the support frame 2 away from the support plate 3, and the end of the auxiliary support assembly away from the mounting plate 5 is connected to the outer rod 7.

[0025] More specifically, when a fast-moving object hits the anti-collision rod 4, the shock force will be transmitted from the support frame 2 to the inner rod 10. After the inner rod 10 is subjected to the shock force, the shock force will be transmitted to the buffer spring 12. The buffer spring 12 can absorb the shock force to a certain extent according to its own characteristics. Finally, this part of the shock force will be transmitted from the outer rod 7 to the robot body 1. The shock force received by the robot body 1 at this time has been dispersed and buffered before, so that the shock force is greatly reduced, thereby reducing the probability of damage to the internal components of the robot body 1.

[0026] Please refer to Figure 2 and Figure 3 The auxiliary support assembly includes a limit block 8 and a clamping ring 9. The upper surface of the limit block 8 is fixedly connected to the side of the mounting plate 5 close to the fixed block 6. The limit block 8 is hinged to one side of the clamping ring 9. The limit block 8 is fastened to the other side of the clamping ring 9 by bolts. A channel for the outer rod 7 to pass through is formed between the limit block 8 and the clamping ring 9, and the outer rod 7 can slide in the channel.

[0027] More specifically, by providing an auxiliary support assembly, a support can be provided at the end of the outer rod 7 away from the fixed block 6. This can prevent the outer rod 7 from being subjected to the gravity pressure of the outer rod 7 itself, the buffer spring 12, the inner rod 10, the support frame 2, the support plate 3 and the anti-collision rod 4 for a long time, which may cause the outer rod 7 to tilt downward or even break, thereby affecting the subsequent anti-collision effect.

[0028] During installation, it is only necessary to align the outer rod 7 with the circular opening between the limit block 8 and the snap ring 9 and fix the limit block 8 and the snap ring 9 with bolts, so that the outer rod 7 can be fixed between the limit block 8 and the snap ring 9, making it difficult for the outer rod 7 to tilt downward.

[0029] Please refer to Figure 4 The inner wall of the spring cavity 701 is provided with a plurality of slide grooves 702 , and the outer wall of one end of the inner rod 10 located in the spring cavity 701 is fixedly connected with a plurality of sliders 11 , and the outer walls of the plurality of sliders 11 are slidably connected with the inner walls of the plurality of slide grooves 702 .

[0030] More specifically, by providing the slide groove 702 and the slider 11, firstly, the inner rod 10 can be prevented from falling out of the spring cavity 701; secondly, the inner rod 10 can be restricted to move only at a specific position, thereby preventing the inner rod 10 from rotating in the spring cavity 701, thereby causing the support frame 2, the support plate 3 and the anti-collision rod 4 to tilt, thereby affecting the anti-collision effect.

[0031] Please refer to Figure 1-Figure 3 , the four support frames 2 are all arranged in multiple layers, and the four support frames 2 in the same layer are fixedly connected with anti-collision rods 4. By arranging the support frames 2 in multiple layers, a larger area can be protected around the robot body 1.

[0032] Please refer to Figure 1-Figure 3 The anti-collision bar 4 is designed as a tubular airbag. By arranging the anti-collision bar 4 as a tubular airbag, the shock force when the object hits instantly can be absorbed or slowed down.

[0033] Please refer to Figure 2 The mounting plate 5 is fastened to the bottom surface of the robot body 1 by bolts. Through the bolt connection, when any one of the components such as the anti-collision bar 4, the support plate 3, the support frame 2 and the buffer assembly needs to be inspected or cleaned, it can be more conveniently separated from the robot body 1.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
