Description

Technical Field

[0001] The utility model relates to the technical field of robot devices, in particular to a protective device for an intelligent robot. Background Art

[0002] Intelligent robots are automated devices that integrate advanced sensors, control systems, and actuators. They are able to perform a range of complex tasks, usually imitating human behavior or completing tasks that are difficult for humans to perform. During operation, intelligent robots may frequently encounter collisions or impacts, which poses certain safety risks to the staff who operate, debug, and maintain the robots. In order to reduce this risk, protective devices are usually installed around the robots.

[0003] During their work, intelligent robots will inevitably encounter collisions and external impacts. Although many robots are equipped with basic protective devices to provide anti-collision functions, the anti-collision effects of these traditional protective measures are often unsatisfactory. Most existing protective devices use simple buffering materials and structures, which cannot effectively absorb and disperse strong impact forces, causing the robots to be easily damaged when subjected to large impacts. In addition, existing protective devices can usually only provide limited protection in specific directions and have poor protection against impacts from multiple directions.

[0004] Therefore, those skilled in the art provide a protective device for an intelligent robot to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology and propose a protective device for an intelligent robot. The protective mechanism and the protection mechanism can effectively absorb the impact on the robot, reduce the damage caused by collision, and thus reduce the maintenance cost and repair frequency of the robot.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A protective device for an intelligent robot, comprising an intelligent robot body, wherein protective mechanisms are provided at both front and rear ends of the intelligent robot body, wherein the two protective mechanisms include two trapezoidal blocks, and protective plates are fixedly provided on opposite sides of the two trapezoidal blocks. Two first compression springs are fixedly provided at both front and rear ends of the intelligent robot body, and four first compression springs are fixedly provided with inclined blocks on opposite sides of two pairs of the first compression springs, and two second rubber blocks are fixedly provided on opposite sides of the four inclined blocks, and two first rubber blocks are fixedly provided on opposite ends of the two trapezoidal blocks.

[0008] Protection mechanisms are provided on both sides of the intelligent robot body, and the two protection mechanisms include two protection plates. Two cylinders are fixedly provided inside the two protection plates. Second sliders are fixedly provided at the output ends of the four cylinders. Connecting pipes are fixedly provided on opposite sides of the four second sliders. Airbags are fixedly provided on opposite sides of the two protection plates. Rotating blocks are rotatably provided on opposite sides of the four second sliders. Connecting blocks are rotatably provided on opposite ends of the four rotating blocks.

[0009] Furthermore, four guide rods are fixedly provided at one opposite end of the two protective plates, and four second compression springs are fixedly provided at one opposite end of the two protective plates. The interiors of the eight second compression springs are respectively sleeved on the outsides of the eight guide rods, and the eight second compression springs are respectively fixed at the front and rear ends of the intelligent robot body at two opposite ends.

[0010] Furthermore, guide blocks are fixedly provided at the upper and lower ends of the two trapezoidal blocks, two guide grooves are provided at the front and rear ends inside the intelligent robot body, and the outsides of the four guide blocks are respectively slidably provided inside the four guide grooves.

[0011] Furthermore, the opposite sides of the four first rubber blocks are respectively slidably arranged on the opposite sides of the four second rubber blocks, and the outsides of the four oblique blocks are respectively slidably arranged at the front and rear ends inside the intelligent robot body.

[0012] Furthermore, the exteriors of the four second sliding blocks are respectively slidably arranged inside the two protection plates, and second springs are fixedly arranged between two of the four second sliding blocks.

[0013] Furthermore, the four rotating blocks are rotatably arranged on opposite sides of the intelligent robot body, and the four connecting tubes are fixedly arranged on opposite sides of the two airbags on opposite sides of the two airbags.

[0014] Furthermore, a first slider is fixedly provided on each opposite side of the four connecting blocks, two fixed rods are fixedly provided on both sides of the interior of the intelligent robot body, the four first sliders slide inside the outside of the fixed rods respectively, and the four first sliders outside are slidably provided on both sides of the interior of the intelligent robot body respectively.

[0015] Furthermore, first springs are fixedly provided at both front and rear ends of the four first sliding blocks, and opposite ends of the eight first springs are fixedly provided at both sides of the interior of the intelligent robot body.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model proposes a protective device for an intelligent robot. When the front and rear ends of the intelligent robot are subjected to external impact, the protective plate will drive the trapezoidal block to move, thereby causing the first rubber block to squeeze the second rubber block on the inclined block, so that the inclined block slides inside the robot and squeezes the first compression spring connected to it. The squeezing of the first and second rubber blocks will generate a large friction force, thereby absorbing and dispersing the generated impact force, thereby reducing the direct impact of the impact force on the main body of the intelligent robot and extending its service life. The guide rod and guide block enable the trapezoidal block to move along a predetermined path when subjected to impact, thereby maintaining the stability of the structure.

[0018] 2. The utility model proposes a protective device for an intelligent robot. When the two sides of the intelligent robot are impacted, the airbag and the protective plate move, prompting the rotating block to rotate, causing the second slider to move in the opposite direction, resulting in the second spring being stretched, and at the same time causing the cylinder to contract, so that the gas inside it is squeezed and then injected into the airbag through the connecting tube, causing the airbag to expand and become larger, thereby absorbing the external impact force and reducing damage to the main body of the intelligent robot. When the rotating block rotates, it will prompt the connecting block to rotate, causing the connecting block to slide on the outside of the fixed rod and generate greater friction, further absorbing the impact energy and protecting the main body of the intelligent robot from damage.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-Figure 3 , an embodiment provided by the utility model:

[0029] A protective device for an intelligent robot includes an intelligent robot body 1, and protective mechanisms 2 are provided at both ends of the intelligent robot body 1. The two protective mechanisms 2 include two trapezoidal blocks 201, and protective plates 207 are fixedly provided on opposite sides of the two trapezoidal blocks 201. Two first compression springs 204 are fixedly provided at both ends of the intelligent robot body 1, and four first compression springs 204 are fixedly provided with oblique blocks 203 on opposite sides of each other. Two second rubber blocks 206 are fixedly provided on opposite sides of each of the four oblique blocks 203. Two first rubber blocks 202 are fixedly provided on opposite ends of the two trapezoidal blocks 201, and four guide rods 209 are fixedly provided on opposite ends of the two protective plates 207. Four second compression springs 208 are fixedly provided at opposite ends of the plate 207, and the interiors of the eight second compression springs 208 are respectively sleeved on the exteriors of the eight guide rods 209. The eight second compression springs 208 are respectively fixed at opposite ends of the intelligent robot body 1 at the front and rear ends. The two trapezoidal blocks 201 are fixed with guide blocks 205 at the upper and lower ends. Two guide grooves 210 are provided at the front and rear ends of the intelligent robot body 1. The exteriors of the four guide blocks 205 are respectively slidably provided in the interiors of the four guide grooves 210. The opposite sides of the four first rubber blocks 202 are respectively slidably provided on the opposite sides of the four second rubber blocks 206. The exteriors of the four oblique blocks 203 are respectively slidably provided at the front and rear ends of the intelligent robot body 1.

[0030] Specifically, when the front and rear ends of the intelligent robot body 1 encounter a collision, the protective plate 207 in the protective mechanism 2 will drive the trapezoidal block 201 connected thereto to move accordingly, prompting the first rubber block 202 on the trapezoidal block 201 to apply pressure to the second rubber block 206 on the oblique block 203, thereby pushing the oblique block 203 to slide inside the intelligent robot body 1. The sliding of the oblique block 203 will compress the first compression spring 204 connected thereto, causing it to shrink inside the intelligent robot body 1. The sliding between the first rubber block 202 and the second rubber block 206 will generate a large friction force, thereby absorbing and dispersing the external impact force. Moreover, the movement of the protective plate 207 will drive the guide rod 209 to move toward the inside of the intelligent robot body 1 and squeeze the second compression spring 208 connected to it to shrink it. The trapezoidal block 201 will also drive the guide block 205 to slide in the guide groove 210, ensuring that the trapezoidal block 201 can move stably along the preset path when impacted, maintaining the stability of the entire structure, and improving the buffering capacity of the intelligent robot body 1 when impacted in the forward and backward directions. When the impact force disappears, the first compression spring 204 and the second compression spring 208 gradually return to their original state, pushing the trapezoidal block 201 and the protective plate 207 back to their initial positions, preparing for the next impact.

[0031] Reference Figures 1-6 , protection mechanisms 3 are provided on both sides of the intelligent robot body 1, and the two protection mechanisms 3 include two protection plates 306, two cylinders 309 are fixedly provided inside the two protection plates 306, and the output ends of the four cylinders 309 are fixedly provided with second sliders 307, and the four second sliders 307 are fixedly provided with connecting pipes 311 on the opposite sides of the two protection plates 306. An airbag 310 is fixedly provided on the opposite sides of the two protection plates 306, and the four second sliders 307 are rotatably provided with rotating blocks 301 on the opposite sides of the two pairs of rotation blocks 301. The four rotating blocks 301 are rotatably provided with connecting blocks 302 on the opposite ends of the two pairs of rotation blocks. The outsides of the four second sliders 307 are respectively slidably provided inside the two protection plates 306, and the four second sliders 307 are fixedly provided with second Spring 308, four rotating blocks 301 are respectively rotated on opposite sides of the intelligent robot body 1, four connecting tubes 311 are respectively fixed on opposite sides of the two airbags 310, four connecting blocks 302 are fixed on opposite sides of each other, two first sliders 305 are fixed on both sides of the intelligent robot body 1, two fixed rods 304 are fixed on both sides of the inside of the intelligent robot body 1, the insides of the four first sliders 305 slide on the outside of the fixed rods 304, the outsides of the four first sliders 305 are respectively slid on both sides of the inside of the intelligent robot body 1, the front and rear ends of the four first sliders 305 are fixed with first springs 303, and the eight first springs 303 are respectively fixed on both sides of the inside of the intelligent robot body 1 at opposite ends;

[0032] Specifically, when both sides of the intelligent robot are impacted, the airbag 310 and the protective plate 306 will move in coordination, and the movement of the protective plate 306 will cause the rotating block 301 to rotate, and then the second slider 307 will move in the opposite direction inside the protective plate 306. The movement of the second slider 307 causes the second spring 308 to be stretched and deformed inside the protective plate 306. At the same time, the movement of the second slider 307 will cause the output end of the cylinder 309 to contract, and the internal gas thereof will be pushed and guided into the airbag 310 through the connecting pipe 311, causing the airbag 310 to expand and form a buffer, thereby effectively absorbing external impact force and reducing damage to the intelligent robot body 1. When the rotating block 301 is rotating, the connecting block connected to it 302 also rotates accordingly, causing the first slider 305 to slide outside the fixed rod 304. The movement of the first slider 305 not only generates a large friction force, but also stretches and squeezes the first spring 303, providing additional protection for both sides of the intelligent robot body 1 to ensure that it is not damaged. Through this multi-level buffering and protection, not only the robot's impact resistance in various environments is improved, but also its stability and reliability are ensured. When the impact force disappears, the first spring 303 and the second spring 308 gradually return to their original state, thereby pushing the first slider 305, the rotating block 301 and the second slider 307 back to their initial positions, causing the output end of the cylinder 309 to extend, causing the gas in the internal part of the airbag 310 to return to the inside of the cylinder 309.

[0033] Working principle: When the front and rear ends of the intelligent robot body 1 encounter a collision, the protective plate 207 in the protective mechanism 2 will drive the trapezoidal block 201 connected thereto to move accordingly, prompting the first rubber block 202 to apply pressure to the second rubber block 206 on the oblique block 203, thereby pushing the oblique block 203 to slide inside the intelligent robot body 1, and at the same time compressing the first compression spring 204 connected thereto. The close contact between the first rubber block 202 and the second rubber block 206 will generate friction, which helps to absorb and disperse the impact force. In addition, the movement of the protective plate 207 will drive the guide rod 209 to move toward the inside of the intelligent robot body 1 and squeeze the second compression spring 208 connected thereto to cause it to contract, and the movement of the trapezoidal block 201 will drive the guide blocks 205 at its upper and lower ends to slide in the guide groove 210, so that the trapezoidal block 201 can move stably along the preset path when impacted, which helps to maintain the stability of the entire structure;

[0034] Secondly, when both sides of the intelligent robot body 1 are impacted, the airbag 310 and the protective plate 306 will move in coordination, causing the rotating block 301 to rotate, causing the second slider 307 connected to its rotation to move in the opposite direction inside the protective plate 306. The movement of the second slider 307 causes the second spring 308 to be stretched and deformed inside the protective plate 306. At the same time, the movement of the second slider 307 will cause the output end of the cylinder 309 to contract. Then, the internal gas is pushed. These gases will be guided into the airbag 310 through the connecting pipe 311, causing the airbag 310 to expand and form a buffer zone, thereby effectively absorbing the external impact force and reducing damage to the intelligent robot body 1. When the rotating block 301 rotates, the connecting block 302 connected to it also rotates, causing the first slider 305 to slide outside the fixed rod 304. The movement of the first slider 305 will generate a large friction force while also stretching and squeezing the first spring 303, thereby providing additional protection for both sides of the intelligent robot body 1 to ensure that it is not damaged.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
