Description

Technical Field

[0001] The utility model relates to the technical field of simulation robots, and particularly relates to a robot joint assembly. Background Art

[0002] A robot is a mechanical device that automatically executes tasks. It can operate according to a preset program or enhance its decision-making process through artificial intelligence technology. Robotics covers a wide range from simple automation devices to complex artificial intelligence systems, and a robot moves through simulation joints arranged inside.

[0003] As shown in the reference case "A Simulation Robot Joint Assembly" with the publication number "CN220680842U", by setting a connection component, a rotating column, a fixed block, and a connecting block, and cooperating with an electric telescopic rod, the function of multi-directional offset of the second power arm is achieved, solving the problem of only being able to bend in one direction and having a small application range. By setting a card slot, a limit block, and an electric push rod, and cooperating with a clamping block, the problem of damage caused by instability of the joint part when the load is large is solved.

[0004] For existing robot joint assemblies, although the joints can be strengthened, they still cannot monitor the pressure on the joints in real time during actual use. If the pressure is too large, there is still a risk of damage to the robot joints. In addition, since the strengthening components are exposed, these components are easily damaged by the external environment during actual use.

[0005] Therefore, a robot joint assembly is proposed to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a robot joint assembly to solve the above problems, improving the existing robot joint assembly, which can strengthen the joints, but still cannot monitor the pressure on the joints in real time during actual use. If the pressure is too large, there is still a risk of damage to the robot joints. In addition, since the strengthening components are exposed, these components are easily damaged by the external environment during actual use.

[0007] The present utility model achieves the above object through the following technical solutions. A robot joint assembly includes a first power arm, on one side of which a second power arm is provided. A detection and protection mechanism for detecting the pressure received by the first power arm and the second power arm is arranged on one side of the first power arm and the second power arm. Among them, the detection and protection mechanism includes a universal joint fixedly installed between the first power arm and the second power arm. Detection components are arranged inside both the first power arm and the second power arm, and a protection component is arranged on the outer sides of the first power arm and the second power arm. During use, the first power arm and the second power arm can freely adjust the angle through the universal joint, so as to be suitable for different use environments. The detection components can be used to monitor the pressure and load borne by the first power arm and the second power arm in real time, ensuring timely adjustment or alarm when the joint is subjected to excessive force, thereby preventing possible damage or failure. The protection component provides additional physical protection for the universal joint to prevent damage caused by external factors.

[0008] Preferably, the detection component includes a connection cavity opened inside the first power arm and the second power arm. Connection disks are fixedly installed on both sides of the universal joint. The two connection disks are respectively slidably connected to the connection cavities of the first power arm and the second power arm. A sealing tube is fixedly installed inside the connection cavity. A piston rod is fixedly installed on one side of the connection disk. One end of the piston rod is slidably connected to the sealing tube. A detection tube is arranged on one side of the sealing tube and is fixedly connected to the connection cavity. A pressure sensor is fixedly installed inside the detection tube. A first piston plate is slidably installed inside the detection tube and is located below the pressure sensor. The detection tube is internally connected and communicated with the sealing tube. When the first power arm and the second power arm are used and are under pressure, they can synchronously drive the corresponding connection disks to move downward, and then push the piston rod to slide inside the sealing tube, causing the hydraulic oil inside the sealing tube to move into the detection tube, allowing the hydraulic oil to push the first piston plate, thereby changing the pressure inside the detection tube. This pressure change is detected by the pressure sensor to monitor the pressure state of the joint in real time.

[0009] Preferably, the detection component further includes a first spring fixedly installed on one side of the first piston plate. The other end of the first spring is fixedly connected to the pressure sensor. The other end of the first spring is fixedly connected to the pressure sensor, so that when the first piston plate moves under pressure, the first spring can provide the necessary reaction force to reset the first piston plate.

[0010] Preferably, two buffer tubes are fixedly installed inside the connection cavity. The two buffer tubes are respectively located on both sides of the sealing tube, and both buffer tubes are communicated with the inside of the sealing tube. A second piston plate is slidably installed inside the buffer tube. One side of the second piston plate is fixedly installed with a second spring, and the other end of the second spring is fixedly connected to the inner top wall of the buffer tube. When the piston rod moves downward, hydraulic oil is simultaneously squeezed into the two buffer tubes, so that the second piston plate is pressured and compresses the second spring, generating an additional buffering effect, avoiding excessive pressure fluctuations and impacts during the movement of the robot, and enhancing the overall impact resistance.

[0011] Preferably, the connection cavity is cylindrical in shape. The protection component is located outside the universal joint. The connection cavity being cylindrical in shape helps to improve the overall strength and pressure resistance of the structure. The protection component located outside the universal joint can protect the universal joint from direct external impacts or damages, thereby extending its service life.

[0012] Preferably, the protection component includes connection rings fixedly installed on the surfaces of the first power arm and the second power arm. A protective sleeve is fixedly installed between the two connection rings. The universal joint is located inside the protective sleeve. The universal joint being located inside the protective sleeve can effectively protect the universal joint from mechanical collisions and environmental factors during the use of the universal joint.

[0013] Preferably, the protection component further includes a plurality of bending grooves formed on the surface and inside of the protective sleeve. The plurality of bending grooves are all annular in shape. The plurality of bending grooves helps to improve the flexibility and adaptability of the protective sleeve, allowing the protective sleeve to bend correspondingly without generating excessive stress when the universal joint moves, thereby reducing the risk of fatigue damage.

[0014] The beneficial effects of the present utility model are:

[0015] 1. When in use, the first power arm and the second power arm can freely adjust the angle through the universal joint, so as to adapt to different use environments. The detection component can monitor the pressure and load borne by the first power arm and the second power arm in real time to ensure timely adjustment or alarm when the joint is subjected to excessive force, thereby preventing possible injuries or failures. The protection component provides additional physical protection for the universal joint to prevent damage caused by external factors.

[0016] 2. The universal joint is located inside the protective sleeve, which can effectively protect the universal joint from mechanical collisions and environmental factors during the use of the universal joint. The plurality of bending grooves helps to improve the flexibility and adaptability of the protective sleeve, allowing the protective sleeve to bend correspondingly without generating excessive stress when the universal joint moves, thereby reducing the risk of fatigue damage.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] During specific implementation: As Figures 1-4 shown, a robot joint assembly includes a first power arm 1, a second power arm 11 is arranged on one side of the first power arm 1, and a detection and protection mechanism 2 for detecting the pressure received by the first power arm 1 and the second power arm 11 is arranged on one side of the first power arm 1 and the second power arm 11. Among them, the detection and protection mechanism 2 includes a universal joint 21 fixedly installed between the first power arm 1 and the second power arm 11. Detection components 22 are arranged inside both the first power arm 1 and the second power arm 11, and a protection component 23 is arranged outside the first power arm 1 and the second power arm 11. When in use, the first power arm 1 and the second power arm 11 can freely adjust the angle through the universal joint 21, so as to adapt to different use environments. The pressure and load borne by the first power arm 1 and the second power arm 11 can be monitored in real time through the detection component 22 to ensure timely adjustment or alarm when the joint receives excessive force, thereby preventing possible damage or failure. The protection component 23 provides additional physical protection for the universal joint 21 to prevent damage caused by external factors.

[0024] As Figure 2 , Figure 3 and Figure 4 shown, the detection component 22 includes a connection cavity 221 opened inside the first power arm 1 and the second power arm 11. Connection plates 223 are fixedly installed on both sides of the universal joint 21. The two connection plates 223 are respectively slidably connected to the connection cavities 221 of the first power arm 1 and the second power arm 11. A sealing tube 222 is fixedly installed inside the connection cavity 221. A piston rod 224 is fixedly installed on one side of the connection plate 223. One end of the piston rod 224 is slidably connected to the sealing tube 222. A detection tube 225 is arranged on one side of the sealing tube 222. The detection tube 225 is fixedly connected to the connection cavity 221. A pressure sensor 228 is fixedly installed inside the detection tube 225. A first piston plate 226 is slidably installed inside the detection tube 225. The first piston plate 226 is located below the pressure sensor 228. The detection tube 225 is internally connected to the sealing tube 222. The pressure sensor 228 is built-in with a controller, which can send induction data while detecting and sensing pressure. Hydraulic oil is provided inside the sealing tube 222 and the detection tube 225. When the first power arm 1 and the second power arm 11 are used under pressure, the corresponding connection plates 223 can be driven to move downward synchronously, thereby pushing the piston rod 224 to slide inside the sealing tube 222, causing the hydraulic oil inside the sealing tube 222 to move into the detection tube 225, enabling the hydraulic oil to push the first piston plate 226, thereby changing the pressure inside the detection tube 225. This pressure change is detected by the pressure sensor 228 to monitor the pressure state of the joint in real time. The detection component 22 further includes a first spring 227 fixedly installed on one side of the first piston plate 226. The other end of the first spring 227 is fixedly connected to the pressure sensor 228. The other end of the first spring 227 is fixedly connected to the pressure sensor 228, so that when the first piston plate 226 moves under pressure, the first spring 227 can provide a necessary reaction force to reset the first piston plate 226;

[0025] Inside the connection cavity 221, two buffer tubes 229 are fixedly installed. The two buffer tubes 229 are respectively located on both sides of the sealing tube 222. Both buffer tubes 229 are internally connected to the inside of the sealing tube 222. A second piston plate 2210 is slidably installed inside the buffer tube 229. On one side of the second piston plate 2210, a second spring 2211 is fixedly installed. The other end of the second spring 2211 is fixedly connected to the inner top wall of the buffer tube 229. The buffer tube 229 is filled with hydraulic oil. When the piston rod 224 moves downward, the hydraulic oil is simultaneously squeezed into the two buffer tubes 229, causing the second piston plate 2210 to be pressured and compress the second spring 2211, generating an additional buffering effect to avoid excessive pressure fluctuations and impacts during the movement of the robot, enhancing the overall impact resistance. The connection cavity 221 is set in a cylindrical shape. The protection component 23 is located outside the universal joint 21. The connection cavity 221 being set in a cylindrical shape helps to improve the overall strength and pressure resistance of the structure. The protection component 23 being located outside the universal joint 21 can protect the universal joint 21 from direct external impacts or damages, thereby extending its service life.

[0026] As Figure 2 and Figure 4 shown, the protection component 23 includes connection rings 231 fixedly installed on the surfaces of the first power arm 1 and the second power arm 11. A protective sleeve 232 is fixedly installed between the two connection rings 231. The universal joint 21 is located inside the protective sleeve 232. The universal joint 21 being located inside the protective sleeve 232 can effectively protect the universal joint 21 from mechanical collisions and environmental factors during the use of the universal joint 21. The protection component 23 further includes a plurality of bending grooves 233 formed on the surface and inside of the protective sleeve 232. The plurality of bending grooves 233 are all set in a ring shape. The plurality of bending grooves 233 help to improve the flexibility and adaptability of the protective sleeve 232, allowing the protective sleeve 232 to bend accordingly without generating excessive stress when the universal joint 21 moves, thereby reducing the risk of fatigue damage.

[0027] When the present utility model is in use, when the first power arm 1 and the second power arm 11 are under pressure, they can synchronously drive the corresponding connecting disc 223 to move downward, thereby pushing the piston rod 224 to slide in the sealing tube 222, causing the hydraulic oil in the sealing tube 222 to move into the detection tube 225, enabling the hydraulic oil to push the first piston plate 226, and then changing the pressure in the detection tube 225. This pressure change is detected by the pressure sensor 228 to monitor the pressure state of the joint in real time. The other end of the first spring 227 is fixedly connected to the pressure sensor 228, so that when the first piston plate 226 moves under pressure, the first spring 227 can provide the necessary reaction force to reset the first piston plate 226. When the piston rod 224 moves downward, the hydraulic oil is synchronously squeezed into the two buffer tubes 229, causing the second piston plate 2210 to be pressured and compress the second spring 2211, generating an additional buffering effect to avoid excessive pressure fluctuations and impacts during the movement of the robot, enhancing the overall impact resistance. The universal joint 21 is located inside the protective sleeve 232, which can effectively protect the universal joint 21 from mechanical collisions and environmental factors when the universal joint 21 is in use. The multiple bending grooves 233 help to improve the flexibility and adaptability of the protective sleeve 232, allowing the protective sleeve 232 to bend accordingly without excessive stress when the universal joint 21 is moving, thereby reducing the risk of fatigue damage.

[0028] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
