SUMMARY

[0004] In view of the above problems, the application provides an integrated joint assembly of an intelligent robot to solve the problems in the background art.

[0005] To achieve the above object, the application provides the following technical scheme.

[0007] The anti-jamming assembly comprises a ring plate, a sliding plate, a first protrusion, a first spring and a second protrusion.

[0008] The ring plate is fixedly installed at the top of the output shaft, a ring groove for installing the ring plate is formed in the bottom of the connecting disc, the ring plate is rotatably installed in the ring groove, equidistant recesses are formed in the inner side of the connecting disc, the number of the sliding plates corresponds to the number of the recesses, the sliding plates are slidably installed in the recesses, the first spring is fixedly connected between the sliding plate and the inner wall of the recess, the first protrusion is arranged on the side of the sliding plate close to the ring plate, the second protrusion is arranged on the outer side of the ring plate, and the first protrusion and the second protrusion are both arranged in the form of an arc-shaped block.

[0009] Furthermore, the number of the second bumps corresponds to the number of the first bumps, and the second bumps are located between two adjacent first bumps and abut against the first bumps.

[0010] Furthermore, the dustproof assembly includes: an airbag, a cavity disposed within the connecting plate, a connecting pipe, a plug plate, a second spring, a push rod, an inclined surface disposed at the bottom of the first protrusion and the slide plate, and an air blowing assembly for blowing air into the connecting plate;

[0011] A circular groove is provided at the bottom edge of the connecting plate. The airbag is annular in shape and fixedly installed in the circular groove. The bottom of the airbag abuts against the top of the output shaft. The cavity is annular. The connecting tube connects the cavity and the airbag. The plug plate is set in the cavity. The number of push rods corresponds to the number of the first protrusion. The push rods are fixedly installed on the top of the plug plate. The top of the push rods extends out of the cavity and abuts against the inclined surface. The second spring is fixedly installed on the bottom of the plug plate.

[0012] Furthermore, the air blowing assembly includes: an annular cavity, an air hole disposed in the connecting plate and communicating with the annular cavity, a micro fan, a filter, a mesh plate, and a sensor;

[0013] The outer side of the connecting plate is provided with an installation groove. The micro fan is fixedly installed in the installation groove. The mesh plate is fixed on the outer side of the connecting plate and closes the installation groove.

[0019] 1. This invention enables the output shaft to continue rotating even when the robot's legs are unable to move, preventing the output shaft from jamming and thus avoiding damage to the joint components due to output shaft jamming. Furthermore, the dustproof component prevents external dust and impurities from entering the gap between the output shaft and the connecting plate, preventing excessive accumulation of dust and impurities in the gap. This would avoid the excessive resistance encountered when the output shaft and connecting plate rotate relative to each other, which could lead to overheating of the output shaft and joint components and affect their service life.

[0020] 2. The airflow generated by the dustproof component of this invention can help dissipate heat when the second protrusion moves relative to the first protrusion, thereby cooling down the output shaft and preventing it from overheating, thus providing overheat protection for the output shaft and joint components.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] This invention provides an integrated joint component for intelligent robots, such as... Figures 1 to 8 As shown, it includes a joint component 1, an output shaft 2 on the joint component 1, the joint component 1 is an integrated joint assembly of intelligent robots in the prior art, i.e. a joint motor, the output shaft 2 is an output shaft on the integrated joint assembly of intelligent robots in the prior art that can rotate freely, a connecting plate 3 is sleeved on the output shaft 2, an anti-jamming component is provided between the output shaft 2 and the connecting plate 3 to prevent the output shaft 2 from jamming, and a dustproof component is provided between the output shaft 2 and the connecting plate 3 to prevent dust from entering;

[0032] The anti-jamming component includes: ring plate 4, sliding plate 5, first protrusion 6, first spring 7, and second protrusion 8;

[0033] The ring plate 4 is fixedly installed on the top of the output shaft 2. The bottom of the connecting plate 3 is provided with an annular groove for installing the ring plate 4. The ring plate 4 is rotatably installed in the annular groove. The inner side of the connecting plate 3 is provided with grooves at equal intervals. The number of sliding plates 5 corresponds to the number of grooves. The sliding plates 5 are slidably installed in the grooves. The first spring 7 fixes the sliding plates 5 to the inner wall of the groove. The first protrusion 6 is provided on the side of the sliding plates 5 near the ring plate 4. The second protrusion 8 is provided on the outer side of the ring plate 4. Both the first protrusion 6 and the second protrusion 8 are arc-shaped blocks.

[0034] Joint 1 is fixed to the robot, and connecting plate 3 is connected to the robot's leg. Activating joint 1 causes output shaft 2 to rotate, which in turn rotates ring plate 4 and second protrusion 8. Second protrusion 8 rotates against first protrusion 6, slide plate 5, and connecting plate 3, thereby moving the robot's leg. When the robot's leg is obstructed and cannot move normally, connecting plate 3 cannot rotate normally and remains stationary. At this time, output shaft 2, along with ring plate 4 and second protrusion 8, presses against the arc surface of first protrusion 6, causing second protrusion 8 and first protrusion 6 to move relative to each other. When first protrusion 6 is pressed, slide plate 5 moves, compressing first spring 7 and causing it to deform and generate force. When the middle part of second protrusion 8 leaves the middle part of first protrusion 6, first spring 7 releases its force, causing slide plate 5 and first protrusion 6 to reset. The subsequent process follows the same principle, so that even if the robot's leg cannot move, output shaft 2 can still rotate, avoiding output shaft 2 from jamming and thus preventing joint 1 from burning out due to output shaft 2 jamming.

[0035] The dustproof component can prevent external dust and impurities from entering the gap between the output shaft 2 and the connecting plate 3, thus preventing excessive accumulation of dust and impurities in the gap. This would prevent the output shaft 2 and the connecting plate 3 from experiencing high resistance when rotating relative to each other, which could lead to overheating of the output shaft 2 and the joint component 1 and affect their service life.

[0036] like Figures 4 to 5 As shown, the number of second protrusions 8 corresponds to the number of first protrusions 6, and the second protrusions 8 are located between two adjacent first protrusions 6 and abut against the first protrusions 6.

[0037] This allows the second protrusion 8 to cooperate with the arc surface to press against the first protrusion 6 when the connecting disc 3 cannot rotate normally, causing the first protrusion 6 to avoid it and ensuring that the second protrusion 8 can move smoothly, thereby ensuring the normal rotation of the output shaft 2.

[0038] like Figure 3 , Figure 6 and Figure 7 As shown, the dustproof assembly includes: an airbag 9, a cavity 10 disposed in the connecting plate 3, a connecting pipe 11, a plug plate 12, a second spring 13, a push rod 14, an inclined surface 15 disposed at the bottom of the first protrusion 6 and the sliding plate 5, and an air blowing assembly for blowing air into the connecting plate 3.

[0039] A circular groove is provided at the bottom edge of the connecting plate 3. The airbag 9 is annular in shape and is fixedly installed in the circular groove. The bottom of the airbag 9 abuts against the top of the output shaft 2. The cavity 10 is annular. The connecting pipe 11 connects the cavity 10 and the airbag 9. The plug plate 12 is set in the cavity 10. The number of push rods 14 corresponds to the number of the first protrusions 6. The push rods 14 are fixedly installed on the top of the plug plate 12. The top of the push rods 14 extends to the outside of the cavity 10 and abuts against the inclined surface 15. The second spring 13 is fixedly installed on the bottom of the plug plate 12.

[0040] When the robot's legs are unobstructed, the airbag 9 is filled with air and contacts the output shaft 2, thus sealing the gap between the output shaft 2 and the connecting plate 3 to prevent dust and impurities from entering. When the robot's legs are obstructed, the connecting plate 3 cannot rotate. As the second protrusion 8 moves, it compresses the first protrusion 6. When the first protrusion 6 is compressed, it and the sliding plate 5 retract into the groove, compressing the first spring 7. At this time, the inclined surface 15 slides relative to the top of the push rod 14. The compressed second spring 13 releases its force, causing the stopper plate 12 and the push rod 14 to rise. As the stopper plate 12 rises, it works with the connecting pipe 11 to draw out the air from the airbag 9, causing the airbag 9 to deflate and leave the output shaft 2. At this time, the rotation of the output shaft 2 will not cause wear to the airbag 9. When the first spring 7 carries the sliding plate 5... When the first protrusion 6 is reset, the first protrusion 6, together with the inclined surface 15, presses the top rod 14 and the plug plate 12 to descend and compress the second spring 13. As the plug plate 12 descends, air is forced into the airbag 9 through the connecting pipe 11, causing the airbag 9 to inflate. When the first protrusion 6 is fully reset, the airbag 9 abuts against the output shaft 2. Therefore, when the connecting plate 3 cannot rotate and remains stationary, the airbag 9 can be separated from the output shaft 2 during the rotation of the output shaft 2, so that the output shaft 2 will not continuously rub against the airbag 9, thus protecting the airbag 9. During the separation of the airbag 9 from the output shaft 2, air is blown by the air blowing component, so that the airflow flows outward from the gap between the output shaft 2 and the connecting plate 3, preventing external dust from entering the gap between the output shaft 2 and the connecting plate 3 when the airbag 9 leaves the output shaft 2.

[0041] In summary, when the connecting plate 3 rotates normally with the output shaft 2, the airbag 9 remains in contact with the output shaft 2, preventing dust and impurities from entering the gap between the output shaft 2 and the connecting plate 3. When the connecting plate 3 cannot rotate normally and remains stationary, the airbag 9 separates from the output shaft 2 during the rotation of the output shaft 2, preventing the airbag 9 from being worn. At the same time, it can generate airflow to blow outward through the gap, preventing external dust from entering the gap between the output shaft 2 and the connecting plate 3 when the airbag 9 leaves the output shaft 2, thus achieving dust prevention throughout the process. Furthermore, when the second protrusion 8 moves relative to the first protrusion 6, the friction between them generates a large amount of heat. The generated airflow can help dissipate the heat and cool down the output shaft 2, preventing it from overheating and thus providing overheat protection for the output shaft 2 and the joint component 1.

[0042] like Figure 3 As shown, the air blowing assembly includes: an annular cavity 16, an air hole 17 disposed in the connecting plate 3 and communicating with the annular cavity 16, a miniature fan 18, a filter screen 19, a mesh plate 20, and a sensor 21;

[0043] The outer side of the connecting plate 3 has an installation groove. The miniature fan 18 is fixedly installed in the installation groove. The mesh plate 20 is fixed on the outer side of the connecting plate 3 and closes the installation groove. Multiple air holes 17 are arranged equidistantly around the inside of the connecting plate 3. The air outlet of the miniature fan 18 is connected to the annular cavity 16. The air inlet of the miniature fan 18 extends through the mesh plate 20 to the outside of the installation groove. The filter screen 19 is threaded into the air inlet of the miniature fan 18. The sensor 21 is fixedly installed in one of the grooves. The connecting plate 3 is equipped with a power supply (not shown in the diagram). The power supply provides power to the sensor 21 and the miniature fan 18.

[0044] When the skateboard 5 moves, the distance between it and the sensor 21 changes. At this time, the sensor 21 controls the micro fan 18 to start, so that the outside air is drawn in, filtered by the filter screen 19, and discharged into the annular cavity 16, and then injected into the connecting plate 3 through the air hole 17 to form an airflow. When the skateboard 5 returns to its original position, the distance between the sensor 21 and the skateboard 5 does not change, so the sensor 21 controls the micro fan 18 to stop.

[0045] like Figure 5 As shown, the surface of the first protrusion 6 is provided with multiple vents 22.

[0046] This facilitates the airflow through the vent 22 and into the gap.

[0047] like Figure 5 As shown, when the connecting plate 3 is connected to the robot part, and the output shaft 2 rotates with the ring plate 4 and the second protrusion 8, the elastic force of the first spring 7 can keep the slide plate 5 and the first protrusion 6 in a relatively stationary state relative to the second protrusion 8.

[0048] This allows the second protrusion 8 to abut against the first protrusion 6 and the slide plate 5, causing the connecting plate 3 and the robot part to rotate when the connecting plate 3 can rotate normally.

[0049] like Figure 5 As shown, sensor 21 is set as an infrared sensor, which integrates detection and control.

[0050] When the distance between sensor 21 and slide plate 5 changes, sensor 21 can control the micro fan 18 to start. The principle of sensor 21 controlling the micro fan 18 to start is existing technology and will not be described in detail here.

[0051] like Figure 3As shown, there is a gap between the connecting plate 3 and the output shaft 2, and the airflow blown out of the air hole 17 can be discharged outward through the gap.

[0052] Working principle: Joint 1 is fixed to the robot, and connecting plate 3 is connected to the robot's legs. Activating joint 1 causes output shaft 2 to rotate, which in turn rotates ring plate 4 and second protrusion 8. Second protrusion 8 rotates against first protrusion 6, sliding plate 5, and connecting plate 3, thereby moving the robot's legs. When the robot's legs are obstructed and cannot move normally, connecting plate 3 cannot rotate normally and remains stationary. At this time, output shaft 2, along with ring plate 4 and second protrusion 8, presses against the arc surface of first protrusion 6, causing second protrusion 8 to move relative to first protrusion 6. When first protrusion 6 is pressed, sliding plate 5 moves, compressing first spring 7 and causing it to deform and generate force. When the middle of second protrusion 8 leaves the middle of first protrusion 6, first spring 7 releases its force, causing sliding plate 5 and first protrusion 6 to reset. The subsequent process follows the same principle, so that even if the robot's legs cannot move, output shaft 2 can still rotate, avoiding jamming of output shaft 2 and thus preventing joint 1 from being burned due to output shaft 2 jamming.

[0053] When the robot's legs are not obstructed, the airbag 9 is filled with air and comes into contact with the output shaft 2, thereby sealing the gap between the output shaft 2 and the connecting plate 3 and preventing dust and impurities from entering the gap.

[0054] When the robot's legs are obstructed, the connecting plate 3 cannot rotate. The movement of the second protrusion 8 compresses the first protrusion 6. When the first protrusion 6 is compressed, it and the sliding plate 5 retract into the groove, compressing the first spring 7. At this time, the inclined surface 15 slides relative to the top of the push rod 14. The compressed second spring 13 releases its force, causing the stopper plate 12 and the push rod 14 to rise. As the stopper plate 12 rises, it works with the connecting pipe 11 to draw air out of the airbag 9, causing the airbag 9 to deflate and leave the output shaft 2. At this time, the rotation of the output shaft 2 will not cause wear to the airbag 9. When the first spring 7, along with the sliding plate 5 and the first protrusion 6, returns to its original position, the first protrusion 6, in conjunction with the inclined surface 15, compresses the push rod 14. The stopper plate 12 descends, compressing the second spring 13. As the stopper plate 12 descends, air is forced into the airbag 9 through the connecting pipe 11, causing the airbag 9 to... When the first protrusion 6 is fully reset, the airbag 9 abuts against the output shaft 2. Therefore, when the connecting plate 3 cannot rotate and remains stationary, the airbag 9 can be separated from the output shaft 2 during the rotation of the output shaft 2. This prevents the output shaft 2 from continuously rubbing against the airbag 9, thus protecting the airbag 9. During the separation of the airbag 9 from the output shaft 2, the slide plate 5 moves, and the distance between it and the sensor 21 changes. At this time, the sensor 21 controls the micro fan 18 to start, so that the outside air is drawn in, filtered by the filter screen 19, and discharged into the annular cavity 16. Then, it is injected into the connecting plate 3 through the air hole 17 to form an airflow and blow air. This allows the airflow to flow outward from the gap between the output shaft 2 and the connecting plate 3, preventing external dust from entering the gap between the output shaft 2 and the connecting plate 3 when the airbag 9 leaves the output shaft 2.

[0055] In summary, when the connecting plate 3 rotates normally with the output shaft 2, the airbag 9 remains in contact with the output shaft 2, preventing dust and impurities from entering the gap between the output shaft 2 and the connecting plate 3. When the connecting plate 3 cannot rotate normally and remains stationary, the airbag 9 separates from the output shaft 2 during the rotation of the output shaft 2, preventing the airbag 9 from being worn. At the same time, it can generate airflow to blow outward through the gap, preventing external dust from entering the gap between the output shaft 2 and the connecting plate 3 when the airbag 9 leaves the output shaft 2, thus achieving dust prevention throughout the process. Furthermore, when the second protrusion 8 moves relative to the first protrusion 6, the friction between them generates a large amount of heat. The generated airflow can help dissipate the heat and cool down the output shaft 2, thus preventing overheating and providing overheat protection for the output shaft 2 and the joint component 1.

[0056] Through the above dustproof treatment, external dust and impurities can be prevented from entering the gap between the output shaft 2 and the connecting plate 3, and the accumulation of too much dust and impurities in the gap can be prevented from getting stuck in the gap between the output shaft 2 and the connecting plate 3, causing the output shaft 2 and the connecting plate 3 to rotate relative to each other with great resistance, resulting in overheating of the output shaft 2 and the joint 1 and affecting the service life.

[0057] When the slide plate 5 is reset, the distance between the sensor 21 and the slide plate 5 does not change, so the sensor 21 controls the micro fan 18 to stop.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
