Description

Technical Field

[0001] This application belongs to the field of robotics technology, specifically relating to a lifting ring assembly for a robot. Background Technology

[0002] Humanoid robots need to adapt to scenarios such as manufacturing, warehousing, logistics, and maintenance. They must frequently withstand combined loads such as vertical lifting and horizontal dragging, and complete the installation and processing of various components or the overall movement through hoisting. To facilitate the lifting of humanoid robots, lifting rings are usually installed. These rings are typically installed directly on key stress points such as the robot's shoulders, back, or base through welding, threaded fastening, or bolting, or they are fixed to the robot's main frame at one or two points using lifting ring screws. The lifting rings are mostly ring-shaped or D-shaped. In order to facilitate the use of lifting hooks, the lifting rings need to be exposed on the robot's surface for a long time. The exposed lifting rings seriously conflict with the robot's biomimetic streamlined appearance design, disrupting the overall visual harmony of the humanoid robot. At the same time, during non-lifting periods, the lifting rings are not only prone to accumulating dust and causing scratches and bumps, but they also increase the robot's space occupation, affecting its mobility in confined spaces. Moreover, the lifting rings that are rigidly connected to the robot's main frame need to be disassembled and replaced after the robot is put into use, which makes the disassembly and assembly process time-consuming and labor-intensive, affecting work efficiency. Utility Model Content

[0003] This application provides a robot lifting ring assembly to solve the technical problems of existing robot lifting rings conflicting with the robot's appearance design, occupying a large space, and being difficult to disassemble.

[0004] The technical solution adopted in this application is as follows: A lifting ring assembly for a robot, the robot including a body, the body having a mounting cavity, and at least one lifting ring assembly on the body, the lifting ring assembly including a fixing member fixed to the mounting cavity and a pressing member disposed on the fixing member, the pressing member having a lifting hole that cooperates with a hook, the pressing member being telescopically disposed relative to the fixing member, so that the pressing member has a lifting state protruding from the surface of the body and a storage state contained in the fixing member. In the stowed state, the top of the pressing part is lower than or flush with the outer surface of the body; in the lifting state, the lifting hole protrudes at least partially from the outer surface of the body.

[0005] The lifting ring assembly of a robot in this application also includes the following additional technical features: The body includes two shoulders, each symmetrically equipped with two hanging ring assemblies. The top surface of the fastener fits against the inner surface of the shoulder facing the mounting cavity. The top surface of the pressing component is inclined. In the retracted state, the inclination angle of the top surface of the pressing component is consistent with the inclination angle of the outer surface of the shoulder.

[0006] The fixing component is provided with a guide groove, and the pressing component is movably disposed in the guide groove. The guide groove is provided with a locking component and an elastic component that cooperate with the pressing component. In the stowed state, the elastic element is in a compressed state, the locking element locks the pressing element, and when the pressing element is pressed, the locking element unlocks, and the elastic element drives the pressing element into the lifting state. When the pressing component is pressed again while it is in the lifting state, the pressing component overcomes the elastic force of the elastic component and moves down along the guide groove. When the locking component locks with the pressing component, the elastic component returns to the compressed state and the pressing component switches to the storage state.

[0007] The pressing part is provided with a positioning hole, which is located on the side of the lifting hole. The locking part is located below the positioning hole. The positioning hole is provided with a connecting part, which includes a rotating end that is rotatably connected to the hole wall of the positioning hole, and a locking end that cooperates with the locking part. The locking end can extend out of the positioning hole and cooperate with the locking part.

[0008] The locking end is provided with a positioning protrusion, and the locking component is provided with a guide groove. The guide groove slides with the positioning protrusion, and the positioning protrusion moves along the guide groove to switch between the storage state and the lifting state.

[0009] The guide groove includes a first guide groove with inlet and outlet ends for the positioning protrusion to enter and exit. The end of the first guide groove is connected to a second guide groove, the depth of which is greater than that of the first guide groove. The end of the second guide groove is connected to a third guide groove, the depth of which is greater than that of the second guide groove. The upper wall of the third guide groove is provided with a locking groove. The lower wall of the third guide groove and the lower wall of the second guide groove form a guide protrusion pointing towards the locking groove. The end of the third guide groove is connected to a fourth guide groove. The fourth guide groove includes a connecting guide groove connected to the third guide groove and a positioning guide groove connected to the connecting guide groove. The depth of the connecting guide groove is greater than that of the third guide groove. The lower wall of the connecting guide groove is provided with a guide groove connected to the guide protrusion. The positioning guide groove includes a ramp, a connecting end connected to the connecting guide groove, and a positioning end connected to the first guide groove. The positioning end is higher than the bottom wall of the first guide groove. The ramp connects the connecting end and the positioning end.

[0010] A mounting groove is provided below the lifting hole. The mounting groove is connected to the positioning hole and the guide groove. The elastic element and the locking element are installed on the bottom wall of the guide groove. The locking element and the elastic element are arranged at intervals relative to each other along a preset direction.

[0011] The upper wall of the mounting groove is provided with a first mounting protrusion, and the bottom wall of the guide groove is provided with a second mounting protrusion opposite to the first mounting protrusion. One end of the elastic element is connected to the first mounting protrusion, and the other end is connected to the second mounting protrusion.

[0012] The fastener includes a main body and a bottom cover. The bottom cover serves as the bottom of the guide groove. The bottom cover is detachably mounted on the main body, and a locking component is mounted on the bottom cover.

[0013] The bottom cover includes a support for mounting the locking element and a positioning arm. The support is mounted on the main body by fasteners. One end of the positioning arm is connected to the support, and the other end extends toward the side away from the support. The main body is provided with a first positioning groove and a second positioning groove. The first positioning groove cooperates with the support, and the second positioning groove cooperates with the positioning arm.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The pressing component of this application is telescopically designed relative to the fixed component, allowing the pressing component to have both a retracted and a lifting state. In the retracted state, the top of the pressing component is lower than or flush with the outer surface of the robot's body, which avoids the pressing component from damaging the robot's original biomimetic streamlined appearance design, ensuring the overall integrity and aesthetics of the product's appearance. The pressing component can switch between the retracted and lifting states without disassembly, which not only eliminates the tedious operation of repeatedly disassembling the lifting ring, but also avoids structural damage to the robot's body during disassembly. In the later maintenance and repair of the robot, there is no need to remove the lifting ring assembly; simply switch the pressing component to the lifting state to engage with the hook for convenient lifting and transportation of the robot. At the same time, the hidden design in the retracted state does not occupy extra space, avoids interference between the lifting ring and other components, and improves the ease of use of the lifting ring assembly.

[0015] 2. As a preferred embodiment of this application, by symmetrically arranging two lifting ring assemblies on the two shoulders, the load can be evenly distributed on both sides of the robot's shoulders during hoisting, effectively achieving force balance and significantly improving the stability and safety of the hoisting process, thus adapting to the center of gravity distribution characteristics of humanoid robots. The top surface of the fixing component fits tightly against the inner surface of the shoulder, which not only increases the contact area between the two and improves the firmness of the connection between the lifting ring assembly and the body, but also disperses the impact force during hoisting through the fitting design, reducing the risk of damage to the shoulder structure; in the folded state, the tilt angle of the top surface of the pressing component is consistent with the outer surface of the shoulder, so that the pressing component and the outer surface of the shoulder form a streamlined contour that connects, eliminating the abruptness of the exposed structure and further enhancing the overall appearance and aesthetics of the robot.

[0016] 3. As a preferred embodiment of this application, the guide groove provides precise movement trajectory constraints for the pressing component, ensuring that the pressing component moves smoothly along a preset path during extension and retraction, avoiding deviation or jamming, and improving the smoothness and structural reliability of switching between lifting and storage states. In the storage state, the elastic element compresses and stores force, and the locking element securely locks it, ensuring the hidden stability of the pressing component when not in use, and storing driving force for the pressing component to pop out in the lifting state. By pressing to unlock, the elastic element drives the pressing component to pop out; pressing again overcomes the elastic force to reset, and the locking element can lock and fix the pressing component. The operation logic allows for switching between lifting and storage states without additional tools, greatly simplifying lifting preparation and storage operations. Moreover, the elastic force of the elastic element replaces rigid external force, making the pressing component pop out more gently and reducing the impact on the robot body, while the locking function of the locking element ensures that the pressing component can be reliably positioned, preventing it from popping out on its own during storage, further improving the safety and durability of the lifting ring assembly.

[0017] Furthermore, the positioning hole is located beside the lifting hole, ensuring proper engagement of the lifting hole with the hook while making efficient use of the internal space of the pressing component. This avoids interference with the lifting function of the lifting hole, achieving both a compact structural layout and functional compatibility. The rotating end of the connector is rotatably connected to the wall of the positioning hole, providing the locking end with flexible swing freedom. This allows it to adaptively adjust its angle as the pressing component moves, ensuring precise engagement between the locking end and the locking component, significantly improving the reliability of the locking and unlocking process. The locking end can extend out of the positioning hole to engage with the locking component below, forming a precise, interlocking locking structure. This ensures the stable locking of the pressing component in the retracted state and allows for smooth separation of the locking end and the locking component during pressing and unlocking. Combined with the constraint of the guide groove, this makes the state switching action smoother.

[0018] 4. In a preferred embodiment of this application, the guide groove provides a clear trajectory constraint for the positioning protrusion, strictly limiting its movement path and preventing the positioning protrusion from shifting, wobbling, or getting stuck during state switching. This significantly improves the accuracy and stability of switching between storage and lifting states. The sliding fit greatly reduces the frictional resistance between components, making the positioning protrusion move more smoothly along the guide groove, making the pressing switching operation less strenuous and more responsive. The positioning protrusion and the guide groove, combined with the rotating section and the hole wall, form a reliable mechanical limiting structure. This structure can firmly lock the pressing part in the storage state to prevent accidental ejection, and can also stably limit its position in the lifting state to prevent state shift due to vibration during lifting, thus improving the stability of the lifting ring assembly in use.

[0019] Furthermore, by setting the first, second, third, and fourth guide grooves, a precise guiding path is provided for the positioning protrusion. Combined with the opening design at the inlet and outlet ends, this ensures unobstructed initial entry of the positioning protrusion and stable subsequent movement along a preset trajectory, preventing deviation or jamming. The locking groove of the third guide groove forms a guiding and locking linkage with the guide protrusion. The guide protrusion precisely guides the positioning protrusion to the locking groove, while the locking groove firmly locks the positioning protrusion, achieving reliable self-locking in the retracted state and preventing accidental ejection of the pressing component. The guide groove of the connecting guide groove connects with the guide protrusion, providing a smooth transition path for the positioning protrusion to disengage from the locking groove. Its greater depth design reduces frictional resistance during disengagement. The inclined platform structure of the positioning guide groove guides the positioning protrusion to move smoothly from the connecting end to the positioning end when the pressing component resets, ultimately returning to the first guide groove via the positioning end, preparing for the next state switch. The design of the positioning end being higher than the bottom wall of the first guide groove creates a pre-positioning effect, preventing the positioning protrusion from wobbling randomly.

[0020] 5. As a preferred embodiment of this application, by providing an installation groove below the lifting hole, and the installation groove below the lifting hole communicating with the positioning hole and the guide groove, the arrangement of the elastic element, the locking element and the connecting element is realized without occupying additional external space, and the precise cooperation of the three can be achieved, making the internal structure of the pressing element more compact and adapting to the space constraints of the robot's mounting cavity.

[0021] Furthermore, the first mounting protrusion and the second mounting protrusion are arranged opposite to each other to form a clear straight force channel, which can strictly limit the lateral displacement, torsion or tilt of the elastic element during the extension and retraction process, ensure that the elastic force of the elastic element is always concentrated and transmitted along the extension and retraction direction of the pressing element, avoid the state switching jam caused by the elastic force deviation, and ensure the smoothness of the lifting and storage state switching.

[0022] 6. As a preferred embodiment of this application, the bottom cover is detachably mounted on the main body. When it is necessary to inspect or replace the locking component or related parts of the guide groove, it is not necessary to disassemble the entire lifting ring assembly or robot body. Only the bottom cover needs to be removed to quickly expose the internal structure. The operation is simple and does not damage other components, significantly reducing maintenance costs and downtime. At the same time, the locking component can be pre-fixed to the bottom cover before assembly with the main body. The positioning reference of the bottom cover can achieve precise alignment between the locking component and the guide groove, ensuring the fitting accuracy between the pressing component and the locking component and improving the overall assembly efficiency.

[0023] Furthermore, the support and the first positioning groove, and the positioning arm and the second positioning groove, form a bidirectional positioning structure to prevent circumferential rotation or axial displacement of the bottom cover, ensuring the fitting accuracy of the locking parts, guide grooves, and pressing parts. The first and second positioning grooves provide a clear installation reference for the bottom cover, eliminating the need for repeated alignment during assembly. The support can be quickly snapped into the first positioning groove and the positioning arm embedded into the second positioning groove, then locked with fasteners. This simplifies the assembly process, reduces the skill requirements for operators, and significantly improves production efficiency. Attached Figure Description

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 As shown, a lifting ring assembly 2 for a robot includes a body 1 with a mounting cavity 11. At least one lifting ring assembly 2 is provided on the body 1. The lifting ring assembly 2 includes a fixing member 3 fixed to the mounting cavity 11 and a pressing member 4 provided on the fixing member 3. The pressing member 4 is provided with a lifting hole 41 that cooperates with a hook. The pressing member 4 is telescopically arranged relative to the fixing member 3 so that the pressing member 4 has a lifting state that protrudes from the surface of the body 1 and a storage state that is accommodated in the fixing member 3. In the stowed state, the top of the pressing member 4 is lower than or flush with the outer surface of the body 1; in the lifting state, the lifting hole 41 protrudes at least partially from the outer surface of the body 1.

[0032] The pressing component 4 of this application is telescopically mounted relative to the fixing component 3, allowing the pressing component 4 to have both a retracted and a lifting state. In the retracted state, the top of the pressing component 4 is lower than or flush with the outer surface of the robot body 1, which avoids the pressing component 4 from damaging the robot's original biomimetic streamlined appearance design and ensures the overall integrity and aesthetics of the product. The pressing component 4 can switch between the retracted and lifting states without disassembly, which not only eliminates the tedious operation of repeatedly disassembling the lifting ring, but also avoids structural damage to the robot body 1 during disassembly. In the later maintenance and repair of the robot, there is no need to remove the lifting ring assembly 2. Simply switch the pressing component 4 to the lifting state to cooperate with the hook for convenient lifting and transportation of the robot. At the same time, the hidden design in the retracted state does not occupy extra space, avoids interference between the lifting ring and other components, and improves the ease of use of the lifting ring assembly 2.

[0033] Hanging hole 41 can be Figure 1 The horizontal tilt setting or horizontal / horizontal setting can also be perpendicular to the horizontal. Figure 1 The orientation of the plane in which it is located. The lifting hole 41 at least partially protrudes from the outer surface of the body 1, so as to... Figure 3For example, in Figure 2 The central lifting hole 41 is at least partially located on the upper side of the outer surface of the body 1.

[0034] As a preferred embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the body 1 includes two shoulders 12, each symmetrically equipped with a lifting ring assembly 2. The top surface of the fixing member 3 is fitted against the inner surface of the shoulder 12 facing the mounting cavity 11. The top surface of the pressing member 4 is inclined, and in the retracted state, the inclination angle of the top surface of the pressing member 4 is consistent with the inclination angle of the outer surface of the shoulder 12. Those skilled in the art will understand that the lifting ring assembly 2 can also be located on the back or chest, and multiple lifting ring assemblies 2 can be provided. By symmetrically arranging two lifting ring assemblies 2 on the two shoulders 12, the load can be evenly distributed on both sides of the robot's shoulders 12 during lifting, effectively achieving force balance, significantly improving the stability and safety of the lifting process, and adapting to the center of gravity distribution characteristics of humanoid robots. The top surface of the fastener 3 fits tightly against the inner surface of the shoulder 12, which increases the contact area between the two and improves the firmness of the connection between the lifting ring assembly 2 and the body 1. The fitting design also disperses the impact force during hoisting, reducing the risk of damage to the shoulder 12 structure. In the storage state, the tilt angle of the top surface of the pressing component 4 is consistent with the outer surface of the shoulder 12, so that the pressing component 4 and the outer surface of the shoulder 12 form a streamlined contour that connects, eliminating the abruptness of the exposed structure and further enhancing the overall appearance and aesthetics of the robot.

[0035] As a preferred embodiment of this application, such as Figure 5 , Figure 6 As shown, the fixing member 3 is provided with a guide groove 31, and the pressing member 4 is movably disposed in the guide groove 31. The guide groove 31 is provided with a locking member 5 and an elastic member 6 that cooperate with the pressing member 4. In the storage state, the elastic element 6 is in a compressed state, the locking element 5 locks the pressing element 4, and when the pressing element 4 is pressed, the locking element 5 is unlocked, and the elastic element 6 drives the pressing element 4 to enter the lifting state. In the lifting state, when the pressing component 4 is pressed again, it overcomes the elastic force of the elastic component 6 and moves downward along the guide groove 31. When the locking component 5 locks with the pressing component 4, the elastic component 6 returns to its compressed state, and the pressing component 4 switches to the retracted state. The guide groove 31 provides precise movement trajectory constraints for the pressing component 4, ensuring that it moves smoothly along a preset path during extension and retraction, avoiding deviation or jamming, and improving the smoothness and structural reliability of the switching between the lifting and retracted states. In the retracted state, the elastic component 6 is compressed and stores force, and the locking component 5 is firmly locked, ensuring the hidden stability of the pressing component 4 when not in use, and storing driving force for the pressing component 4 to pop out in the lifting state. By pressing to unlock, the elastic component 6 drives the pressing component 4 to pop out. Pressing again overcomes the elastic force to reset, and the locking component 5 can lock and fix the pressing component 4. This operation logic allows the switching between the lifting and retracted states to be completed without additional tools, greatly simplifying the lifting preparation and retracted operation. Moreover, the elastic force of the elastic element 6 replaces the rigid external force, making the pop-out process of the pressing element 4 gentler and reducing the impact on the robot body 1. The locking function of the locking element 5 ensures that the pressing element 4 can be reliably positioned, preventing it from popping out on its own during storage, further improving the safety and durability of the lifting ring assembly 2.

[0036] As a preferred embodiment of the second implementation method, such as Figure 6 , Figure 7 As shown, the pressing component 4 has a positioning hole 42, which is located beside the lifting hole 41. The locking component 5 is located below the positioning hole 42. A connecting component 43 is located within the positioning hole 42. The connecting component 43 includes a rotating end 431 rotatably connected to the wall of the positioning hole 42, and a locking end 432 that cooperates with the locking component 5. The locking end 432 can extend out of the positioning hole 42 to cooperate with the locking component 5. The positioning hole 42 is located beside the lifting hole 41, ensuring that the lifting hole 41 can properly cooperate with the hook while making reasonable use of the internal space of the pressing component 4, avoiding interference with the lifting function of the lifting hole 41, and achieving a compact structural layout and functional compatibility. The rotating end 431 of the connecting component 43 is rotatably connected to the wall of the positioning hole 42, providing the locking end 432 with flexible swing freedom, allowing it to adaptively adjust its angle as the pressing component 4 moves, ensuring that the locking end 432 can accurately cooperate with the locking component 5, significantly improving the reliability of the locking and unlocking process. The locking end 432 can extend out of the positioning hole 42 and cooperate with the locking part 5 below to form a locking structure that corresponds to the upper and lower parts and precisely engages. This ensures that the pressing part 4 is firmly locked in the storage state, and that the locking end 432 and the locking part 5 can be smoothly separated by the swing of the rotating end 431 when pressing to unlock. With the constraint of the guide groove 31, the state switching action is smoother.

[0037] As a preferred specific example under Embodiment 1, such as Figure 6 , Figure 10As shown, the locking end 432 is provided with a positioning protrusion 433, and the locking member 5 is provided with a guide groove 51. The guide groove 51 and the positioning protrusion 433 are slidably engaged. The positioning protrusion 433 moves along the guide groove 51 to switch between the storage state and the lifting state. The guide groove 51 provides a clear movement trajectory constraint for the positioning protrusion 433, strictly limiting its movement path and preventing the positioning protrusion 433 from deviating, shaking, or getting stuck during the state switching process, which significantly improves the accuracy and stability of the switching between the storage and lifting states. The sliding engagement greatly reduces the frictional resistance between the components, making the positioning protrusion 433 move more smoothly along the guide groove 51, making the pressing switching operation less strenuous and more responsive. The positioning protrusion 433 and the guide groove 51 are combined with the rotating section and the hole wall to form a reliable mechanical limiting structure. This structure can firmly lock the pressing member 4 in the storage state to prevent it from accidentally popping out, and can also stably limit the position in the lifting state to prevent state deviation caused by vibration during the lifting process, thus improving the stability of the lifting ring assembly 2 in the use state.

[0038] Furthermore, such as Figure 6 , Figure 7As shown, the guide groove 51 includes a first guide groove 511, which has an inlet / outlet end 512 for the positioning protrusion 433 to enter and exit. The end of the first guide groove 511 is connected to a second guide groove 513, the depth of which is greater than that of the first guide groove 511. The end of the second guide groove 513 is connected to a third guide groove 514, which has a greater depth than that of the second guide groove 513. The upper wall of the third guide groove 514 has a locking groove 515. The lower wall of the third guide groove 514 and the lower wall of the second guide groove 513 form a guide protrusion 516 pointing towards the locking groove 515. The end of the third guide groove 514 is connected to a fourth guide groove 517. The four guide grooves 517 include a connecting guide groove 5171 connected to the third guide groove 514 and a positioning guide groove 5172 connected to the connecting guide groove 5171. The depth of the connecting guide groove 5171 is greater than the depth of the third guide groove 514. The lower wall of the connecting guide groove 5171 is provided with a guide groove 5173 connected to the guide protrusion 516. The positioning guide groove 5172 includes a ramp 5174, a connecting end 5175 connected to the connecting guide groove 5171, and a positioning end 5176 connected to the first guide groove 511. The positioning end 5176 is higher than the bottom wall of the first guide groove 511. The ramp 5174 connects the connecting end 5175 and the positioning end 5176. By setting the first guide groove 511, the second guide groove 513, the third guide groove 514, and the fourth guide groove 517, a precise guiding path is provided for the positioning protrusion 433. Combined with the opening design of the inlet and outlet end 512, this ensures that the positioning protrusion 433 enters without obstruction initially and moves stably along a preset trajectory afterwards, avoiding deviation or jamming. The locking groove 515 of the third guide groove 514 forms a guiding and locking linkage with the guide protrusion 516. The guide protrusion 516 can precisely guide the positioning protrusion 433 to the locking groove 515, while the locking groove 515 can firmly lock the positioning protrusion 433, achieving reliable self-locking in the retracted state and preventing the pressing part 4 from accidentally popping out. The guide groove 5173 connecting the guide groove 5171 connects with the guide protrusion 516, providing a smooth transition path for the positioning protrusion 433 to disengage from the locking groove 515. Combined with its greater depth design, this reduces frictional resistance during disengagement. The inclined platform 5174 structure of the positioning guide groove 5172 guides the positioning protrusion 433 to move smoothly from the connecting end 5175 to the positioning end 5176 through the inclined surface when the pressing part 4 is reset. Finally, it returns to the first guide groove 511 through the positioning end 5176, preparing for the next state switch. The design of the positioning end 5176 being higher than the bottom wall of the first guide groove 511 can form a pre-positioning effect and prevent the positioning protrusion 433 from shaking randomly.

[0039] As a preferred specific example 2 under implementation 1, such as Figure 6As shown, a mounting groove 44 is provided below the lifting hole 41. The mounting groove 44 is connected to the positioning hole 42 and the guide groove 31. The elastic element 6 and the locking element 5 are installed on the bottom wall of the guide groove 31. The locking element 5 and the elastic element 6 are arranged at intervals relative to each other along a preset direction. By providing a mounting groove 44 below the lifting hole 41, which is connected to the positioning hole 42 and the guide groove 31, the arrangement of the elastic element 6, the locking element 5 and the connecting element 43 is realized without occupying additional external space. It also enables the precise cooperation of the three, making the internal structure of the pressing element 4 more compact and adapting to the space constraints of the robot's mounting cavity 11.

[0040] Furthermore, such as Figure 6 As shown, the upper wall of the mounting groove 44 is provided with a first mounting protrusion 45, and the bottom wall of the guide groove 31 is provided with a second mounting protrusion 32 opposite to the first mounting protrusion 45. One end of the elastic member 6 is connected to the first mounting protrusion 45, and the other end is connected to the second mounting protrusion 32. The first mounting protrusion 45 and the second mounting protrusion 32 are opposite to each other, forming a clear straight force channel, which can strictly limit the lateral displacement, torsion, or tilt of the elastic member 6 during the extension and retraction process, ensuring that the elastic force of the elastic member 6 is always concentrated and transmitted along the extension and retraction direction of the pressing member 4, avoiding state switching jamming caused by elastic force deviation, and ensuring smooth switching between lifting and storage states.

[0041] As a preferred embodiment of the second implementation method, such as Figure 5 , Figure 6 As shown, the fixing component 3 includes a main body 33 and a bottom cover 34. The bottom cover 34 serves as the bottom of the guide groove 31 and is detachably mounted on the main body 33. The locking component 5 is mounted on the bottom cover 34. Because the bottom cover 34 is detachably mounted on the main body 33, when it is necessary to inspect or replace the locking component 5 or related components of the guide groove 31, it is not necessary to disassemble the entire lifting ring assembly 2 or the robot body 1. Only the bottom cover 34 needs to be removed to quickly expose the internal structure. This operation is simple and does not damage other components, significantly reducing maintenance costs and downtime. Simultaneously, the locking component 5 can be pre-fixed to the bottom cover 34 before assembly with the main body 33. The positioning reference of the bottom cover 34 enables precise alignment between the locking component 5 and the guide groove 31, ensuring the fitting accuracy between the pressing component 4 and the locking component 5 and improving overall assembly efficiency.

[0042] Furthermore, such as Figure 5 , Figure 6 , Figure 8 , Figure 11As shown, the bottom cover 34 includes a support 341 for mounting the locking member 5 and a positioning arm 342. The support 341 is mounted on the main body 33 by fasteners (not shown in the figures). One end of the positioning arm 342 is connected to the support 341, and the other end extends towards the side opposite to the support 341. The main body 33 is provided with a first positioning groove 331 and a second positioning groove 332. The first positioning groove 331 cooperates with the support 341, and the second positioning groove 332 cooperates with the positioning arm 342. Those skilled in the art will understand that the fasteners can be screws. The support 341 and the first positioning groove 331, and the positioning arm 342 and the second positioning groove 332 form a bidirectional positioning structure, preventing circumferential rotation or axial displacement of the bottom cover 34 and ensuring the fitting accuracy of the locking member 5 with the guide groove 31 and the pressing member 4. The first positioning groove 331 and the second positioning groove 332 provide a clear installation reference for the bottom cover 34. During assembly, there is no need for repeated alignment. The support 341 can be quickly snapped into the first positioning groove 331 and the positioning arm 342 can be embedded into the second positioning groove 332. Then, it can be locked with fasteners. This simplifies the assembly process, reduces the skill requirements for operators, and significantly improves production efficiency.
