Detailed Implementation
[0064] To further understand the content of this invention, please refer to the accompanying drawings. Figure 1-39 The present invention will be described in detail with reference to the embodiments.
[0065] Combined with appendix Figure 1-39This embodiment of a wheeled robot includes a drive steering mechanism 101 and a ground-operating structure 102. A fixed chassis 1011 is mounted on the drive steering mechanism 101, and the ground-operating structure 102 is mounted on the fixed chassis 1011. The ground-operating structure 102 includes a fixed base 8, a movable base 2, and a frame assembly 1. The fixed base 8 is mounted on the fixed chassis 1011, and the movable base 2 and the fixed base 8 are slidably connected. The fixed base 8 is provided with a transmission mechanism to drive the movable base 2. The frame assembly 1 is located on the movable base 2, and the movable base 2 is provided with a rotation and lifting mechanism 7 to rotate and raise the frame assembly 1. The robot also includes a control system. The transmission mechanism and the control system are electrically connected, and the rotation and lifting mechanism 7 is electrically connected to the control system. The frame assembly 1 is provided with a telescopic mechanism 3, and an actuator 4 is provided at the end of the telescopic mechanism 3.
[0066] The drive steering mechanism 101 includes a rolling wheel E2, a connecting frame E3, a steering drive mechanism E4, and a travel drive mechanism E5. The steering drive mechanism E4 is housed within a fixed housing E1, which is mounted on a fixed chassis 1011. The output shaft of the steering drive mechanism E4 is drivenly connected to one end of the connecting frame E3, which is bearing-connected to the fixed housing E1. The other end of the connecting frame E3 is fixedly connected to the travel drive mechanism E5. The travel drive mechanism E5 is mounted on the connecting frame E3 via a travel drive motor housing. The output shaft of the travel drive mechanism E5 is drivenly connected to the rolling wheel E2, and the travel drive motor housing is bearing-connected to the rolling wheel E2. The steering drive mechanism E4 drives the rolling wheel E2 to turn via the connecting frame E3 and the travel drive mechanism E5, and the travel drive mechanism E5 drives the rolling wheel E2 to rotate. The steering drive mechanism E4 and the travel drive mechanism E5 are both electrically connected to the control system.
[0067] The connecting frame E3 has a suspension mechanism, comprising a second connecting member E31 and a third connecting member E32, which are slidably connected. The second connecting member E31 is drive-connected to the output shaft of the steering drive mechanism E4, and the third connecting member E32 is fixedly connected to the drive motor housing of the drive drive mechanism E5. The suspension mechanism includes a shock-absorbing elastic member E33 disposed between the second connecting member E31 and the third connecting member E32. A pre-compression structure is provided between the second connecting member E31 and the third connecting member E32 to compress the shock-absorbing elastic member E33. The pre-compression structure includes a pre-compression member E34 disposed on one of the second connecting member E31 and the third connecting member E32, and a connecting portion E35 disposed on the other. The pre-compression member E34 and the connecting portion E35 are connected; when the pre-compression member E34 and the connecting portion E35 are connected, the shock-absorbing elastic member E33 is in a compressed state. In this embodiment, the preload member E34 is a connecting shaft located on the third connecting member E32, and the connecting part E35 is a connecting hole located on the second connecting member E31. The connecting shaft passes through the connecting hole, and a preload nut is provided at the end of the connecting shaft. The preload nut and the third connecting member E32 abut against each other to prevent the connecting shaft from disengaging from the connecting hole. The shock-absorbing elastic member E33 is a spring. One end of the shock-absorbing elastic member E33 is connected to the second connecting member E31, and the other end is connected to the third connecting member E32. The second connecting member E31 and the third connecting member E32 are slidably connected through the cooperation of the connecting shaft and the connecting hole, so that the second connecting member E31 slides axially relative to the third connecting member E32 but is circumferentially fixed, allowing the second connecting member E31 to transmit torque through the third connecting member E32. The compression state of the shock-absorbing elastic member E33 can increase the rigidity of the shock-absorbing elastic member E33. When the rolling wheel E2 jumps, the elastic change of the shock-absorbing elastic member E33 will not be too large, preventing the ground knife operating structure 102 from becoming unstable.
[0068] One of the second connecting member E31 and the third connecting member E32 is provided with a sliding rail E36, and the other is provided with a sliding block E37 that cooperates with the sliding rail E36. The second connecting member E31 and the third connecting member E32 are slidably connected through the sliding rail E36 and the sliding block E37. The steering drive mechanism E4 includes a rotary drive motor, a reducer and an encoder connected in sequence.
[0069] An angle limiting structure is provided between the connecting frame E3 and the fixed shell E1 to limit the rotation angle of the connecting frame E3. The angle limiting structure includes an angle constraint member E41 and a constrained member E42. The angle constraint member E41 is fixedly connected to the fixed shell E1, and the constrained member E42 is directly or indirectly fixedly connected to the connecting frame E3. After the constrained member E42 rotates to a fixed angle, it abuts against one side of the angle constraint member E41. After the constrained member E42 reverses to a fixed angle, it abuts against the other side of the angle constraint member E41. In this embodiment, the constrained member E42 is cylindrical, and one side of the constrained member E42 has a notch E421. Part of the angle constraint member E41 is located inside the notch E421. After the constrained member E42 rotates to a fixed angle, the bottom wall of the notch E421 abuts against one side of the angle constraint member E41. After the constrained member E42 rotates to the opposite direction to a fixed angle, the bottom wall of the notch E421 abuts against the other side of the angle constraint member E41.
[0070] The fixed base 8 is provided with a second slide rail 81, and the movable base 2 is provided with a second slider that cooperates with the slide rail. The transmission mechanism includes a second motor 82, a screw 83, and a feed member 84. The second motor 82 is fixedly connected to the fixed base 8, the screw 83 is connected to the fixed base 8 through bearings, and the feed member 84 is located on the movable base 2. The feed member 84 has a threaded hole that cooperates with the screw 83. The second motor 82 drives the screw 83 to rotate through a synchronous belt and a synchronous pulley. The rotation of the screw 83 can drive the movable base 2 to slide on the second slide rail 81.
[0071] The rotary lifting mechanism 7 includes a first driving component 71, a second driving component 72, a bottom nut 73, an upper nut 74, and a ball screw 75. The ball screw 75 is fixed to the movable base 2. The bottom nut 73 and the upper nut 74 are both sleeved on the ball screw 75. The bottom nut 73 includes a first inner ring and a first outer ring, which are connected by a bearing. The first inner ring is sleeved around the ball screw 75 and is keyed to the ball screw 75. The first inner ring can only move linearly relative to the ball screw 75, being circumferentially fixed and axially sliding relative to the ball screw 75. The first outer ring is fixedly connected to the frame assembly 1. The upper nut 74 includes a second inner ring and a second outer ring, which are connected by a bearing. The second inner ring has a thread that mates with the ball screw 75. The second outer ring is fixedly connected to the frame assembly 1. The first drive unit 71 and the second drive unit 72 are both mounted on the frame assembly 1. The output shaft of the first drive unit 71 is connected to the first inner ring synchronous belt, and the output shaft of the second drive unit 72 is connected to the second inner ring synchronous belt.
[0072] Both the bottom nut 73 and the top nut 74 are mounted on the frame assembly 1. A synchronous pulley is fixed to the output shaft of the first drive component 71, and a synchronous pulley is fixed to the first inner ring of the bottom nut 73, with a synchronous belt surrounding the pulley. A synchronous pulley is fixed to the output shaft of the second drive component 72, and a synchronous pulley is fixed to the second inner ring of the top nut 74, with a synchronous belt surrounding the pulley. The frame assembly 1 can achieve rotational motion, linear motion, and a combination of linear and rotational motion through the rotary lifting mechanism 7.
[0073] Specifically, the linear-rotational composite motion is achieved by activating the first drive member 71. Since the first inner ring is circumferentially fixed relative to the ball screw 75, activating the first drive member 71 will drive the frame assembly 1 to rotate around the ball screw 75. The rotation of the frame assembly 1 will cause the second inner ring to rotate through the synchronous belt transmission between the second drive member 72 and the second inner ring. The rotation of the second inner ring will drive the frame assembly 1 to perform linear motion relative to the ball screw 75.
[0074] Linear motion is achieved by activating the second drive unit 72. Activating the second drive unit 72 drives the second inner ring to rotate, and the rotation of the second inner ring causes the frame assembly 1 to move linearly relative to the ball screw 75.
[0075] The rotational motion is achieved by simultaneously activating the first drive member 71 and the second drive member 72. As described above, activating the first drive member 71 enables the linear-rotational combined motion of the frame assembly 1. At this time, it is only necessary to reverse the second drive member 72 and keep its rotational speed consistent with that of the first drive member 71 to keep the second inner ring stationary. Therefore, the frame assembly 1 will not perform linear motion, but only rotational motion.
[0076] A limiting structure for restricting the rotation angle of the frame assembly 1 is provided between the frame assembly 1 and the ball screw 75. The limiting structure includes a limiting member 13 and a blocking member. The limiting member 13 is fixed to the frame assembly 1, and the blocking member is directly or indirectly fixedly connected to the first inner ring / ball screw 75. The blocking member has two stops 761, and the limiting member 13 is limited between the two stops 761. In a specific application, the blocking member is fixed to the timing pulley of the first inner ring.
[0077] It also includes a detection mechanism, which comprises a first sensor 12 and a first sensing element 76. The first sensor 12 is fixed to the frame assembly 1, and the first sensing element 76 is directly or indirectly fixedly connected to the first inner ring. The first sensor 12 can sense the first sensing element 76. The first sensor 12 is electrically connected to the control system. In specific applications, the first sensing element 76 and the blocking element are integrated. The first sensing element 76 has a metal part and is a sensor that can sense metal. When the first sensor 12 senses the first sensing element 76, the position of the frame assembly 1 is set to the origin position, and then the rotation angle of the frame assembly 1 is confirmed by the encoder of the first drive element 71.
[0078] The detection mechanism also includes a second sensor 21 and a second sensing element 77. The second sensor 21 is fixed to the movable base 2, and the second sensing element 77 is directly or indirectly fixedly connected to the first inner ring. The second sensor 21 can sense the second sensing element 77. The second sensor 21 is electrically connected to the control system. In specific applications, the second sensing element 77 is a metal part, and the second sensor 21 is a sensor capable of sensing metal. When the frame assembly 1 moves to the bottom, the second sensing element 77 reaches the position of the second sensor 21, and the second sensor 21 senses the second sensing element 77 and transmits the sensing signal to the control system. The fixed base 8 is provided with a fourth sensor, and the movable base 2 is provided with a fourth sensing element. The fourth sensor can sense the fourth sensing element. In specific applications, the fourth sensing element is a metal part, and the fourth sensor is a sensor capable of sensing metal. When the movable base 2 moves to the end of the fixed base 8, the fourth sensing element reaches the position of the fourth sensor, and the fourth sensor senses the fourth sensing element and transmits the sensing signal to the control system.
[0079] The telescopic mechanism 3 includes a drive mechanism and a lead screw telescopic mechanism mounted on the frame assembly 1. The drive mechanism and the control system are electrically connected. The drive mechanism includes a first motor 31, and the lead screw telescopic mechanism includes a lead screw 32 and a feed assembly that cooperates with the lead screw 32. The lead screw 32 and the frame assembly 1 are connected by bearings. The output shaft of the first motor 31 is equipped with a synchronous pulley, and the lead screw 32 is fixedly equipped with a synchronous pulley. The first motor 31 drives the lead screw 32 to rotate through the synchronous belt and the synchronous pulley. The feed assembly and the frame assembly 1 are slidably connected. The frame assembly 1 includes an outer sleeve assembly 11, which is sleeved on the outside of the feed assembly. The feed assembly includes a feed nut 33 and a feed sleeve 34. The feed nut 33 and the feed sleeve 34 are fixedly connected, and the outer sleeve assembly 11 and the feed sleeve 34 are keyed together, so that the feed assembly and the outer sleeve assembly 11 are circumferentially fixed and axially sliding relative to each other. The frame assembly 1 is equipped with a rotary drive, which is electrically connected to the control system. The rotary drive drives the outer sleeve assembly 11 to rotate, which in turn drives the feed sleeve 34 to rotate. The actuator 4 is located at the end of the feed sleeve 34.
[0080] When the frame assembly 1 is working, the control system controls the first motor 31 to drive the lead screw extension mechanism to extend and retract, bringing the actuator 4 closer to the switch cabinet switch that is being operated. Then, the control system controls the rotary drive output shaft to rotate, driving the actuator 4 to rotate and thus opening the switch cabinet switch. Since the rotation of the rotary drive also drives the feed assembly to rotate, it will cause the feed assembly to move relative to the lead screw 32. To solve this problem, the control system only needs to control the lead screw 32 to rotate in the opposite direction via the first motor 31.
[0081] It also includes a pressure cap assembly 5, which is connected to the feed sleeve 34 by a bearing. Typically, switchgear switches have a grounding switch docking hole baffle. Before operating the switchgear switch, the grounding switch docking hole baffle needs to be opened. The pressure cap assembly 5 is used to open the grounding switch docking hole baffle of the switchgear. The pressure cap assembly 5 includes a pressure cap end 51, a first connecting member 53, and a mounting bracket 54. One end of the first connecting member 53 is fixedly connected to the pressure cap end 51, and the other end of the first connecting member 53 is fixedly connected to the mounting bracket 54. The mounting bracket 54 is connected to the feed sleeve 34 by a bearing. The pressure cap end 51 is a pressure plate with sides on both sides. Each side of the pressure plate has an adjusting member 52, which has an inwardly extending inclined surface. In this embodiment, the adjusting member 52 has two inclined surfaces, namely a first inclined surface 521 and a second inclined surface 522, which are adjacent surfaces. Both the first inclined surface 521 and the second inclined surface 522 are triangular surfaces. The junction of the first inclined surface 521 and the second inclined surface 522 is smoothly transitioned by a curved surface. The first inclined surface 521 faces the front of the pressure cap end, and the second inclined surface 522 faces the bottom of the pressure cap end. An ejector elastic element 523 is provided between the two sides of the adjusting member and the pressure plate to keep the adjusting member in the pop-out state. In specific applications, the ejector elastic element 523 is a spring.
[0082] The pressure end 51 opens the grounding switch docking hole baffle by pressing down. When the grounding switch docking hole baffle enters the pressure end 51, if the surfaces of the pressure end 51 and the grounding switch docking hole baffle are not parallel, or if the pressure end 51 and the grounding switch docking hole baffle are slightly misaligned, after the first inclined surface 521 / second inclined surface 522 of the two adjusting components contacts the grounding switch docking hole baffle, the pressure end 51 presses down, and the force generated between the first inclined surface 521 / second inclined surface 522 and the grounding switch docking hole baffle causes the pressure end assembly 5 to rotate slightly relative to the feed sleeve 34, so that the pressure end 51 and the grounding switch docking hole baffle return to a parallel state, so that the pressure end 51 can accurately dock with the grounding switch docking hole baffle of the switch cabinet. Furthermore, the two adjusting components limit the grounding switch docking hole baffle to the middle position of the pressure end 51, so that the pressure end 51 can maintain stability when applying a downward pressing force to the grounding switch docking hole baffle.
[0083] In another embodiment, the telescopic mechanism 3 includes a drive mechanism and a lead screw telescopic mechanism disposed on the frame assembly 1. The drive mechanism is electrically connected to the control system. The drive mechanism includes a first motor 31, and the lead screw telescopic mechanism includes a lead screw 32 and a feed assembly that cooperates with the lead screw 32. The first motor 31 is fixed to the frame assembly 1, and the lead screw 32 is bearing-connected to the frame assembly 1. The first motor 31 and the lead screw 32 are drively connected. The feed assembly includes a feed nut 33, a pusher 35, a pressure cap assembly 5, and a feed sleeve 34. The feed nut 33 is sleeved on the lead screw 32. The feed nut 33 and the pusher 35 are fixedly connected. The pusher 35 and the pressure cap assembly 5 are fixedly connected. The pressure cap assembly 5 and the feed sleeve 34 are bearing-connected. The frame assembly 1 includes an outer sleeve assembly 11, which is sleeved on the outside of the feed sleeve 34. The feed sleeve 34 and the outer sleeve assembly 11 are keyed together. The outer sleeve assembly 11 restricts the feed sleeve 34 to only perform linear motion. The feed sleeve 34 is circumferentially fixed relative to the outer sleeve assembly 11 and axially relative to it.
[0084] The frame assembly 1 also includes a fixed frame 15, on which a first motor 31 is mounted. A pusher 35 is slidably connected to the fixed frame 15. The fixed frame 15 has a first slide rail, and the pusher 35 has a first slider 351 that mates with the first slide rail. The cap assembly 5 includes a cap end 51, a first connecting member 53, and a mounting bracket 54. One end of the first connecting member 53 is fixedly connected to the cap end 51, and the other end is fixedly connected to the mounting bracket 54. The mounting bracket 54 and the feed sleeve 34 are connected via bearings, and the mounting bracket 54 and the pusher 35 are also fixedly connected. The cap end 51 is a pressure plate with side edges on both sides. The output shaft of the first motor 31 rotates, driving a lead screw 32 to rotate, causing the feed nut 33 to drive the pusher 35, the cap assembly 5, and the feed sleeve 34 in linear motion. Because the cap assembly 5 and the pusher 35 are fixedly connected, the cap assembly 5 will not deflect relative to the feed sleeve 34. Since the gland assembly 5 and the feed sleeve 34 are connected by a bearing, the rotary drive drives the outer sleeve assembly 11 to rotate, which in turn drives the feed sleeve 34 and the actuator 4 to rotate, thus preventing the feed assembly from moving.
[0085] The frame assembly 1 is equipped with a fifth sensor, and the feed assembly is equipped with a fifth sensor element. The fifth sensor element is a metal component, and the fifth sensor is a sensor capable of sensing metal. When the feed nut 33 is at the open end of the lead screw 32, the fifth sensor element is in the position of the fifth sensor element. The fifth sensor element is electrically connected to the control system. When the fifth sensor element senses the position of the fifth sensor element, it transmits a sensing signal to the control system, and the control system determines that the feed assembly has returned to its original position. In specific applications, the fifth sensor element is located on the pusher 35, and the fifth sensor element is located on the fixed frame 15.
[0086] An actuator 4 is provided at the end of the feed sleeve 34. The actuator 4 includes a transmission component 41 and an actuator 42. One end of the actuator 42 is slidably connected to one end of the transmission component 41, and the actuator 42 is circumferentially fixed relative to the transmission component 41 while being axially slidable relative to it. One of the actuator 42 and the transmission component 41 has a non-cylindrical body, and the other has a moving hole 422 that matches the shape of the non-cylindrical body. In specific applications, the non-cylindrical body can be a square prism or a regular pentagonal prism, and the actuator 42 and the transmission component 41 can also be connected by a key. Furthermore, an elastic buffer 43 is provided between one end of the actuator 42 and one end of the transmission component 41. In specific applications, the elastic buffer 43 is a spring, and the elastic buffer 43 is sleeved on the non-cylindrical body. The other end of the transmission component 41 is fixedly connected to the feed sleeve 34. The actuator 4 also includes a limiting member 44, which is sleeved on a non-circular cylinder. One end of the limiting member 44 is fixedly connected to the transmission member 41, and the other end of the limiting member 44 has a first abutment 441. The actuator 42 has a second abutment 421. When the actuator 42 moves to a fixed position relative to the transmission member 41, the first abutment 441 abuts against the second abutment 421 to prevent the actuator 42 from disengaging from the limiting member 44. The other end of the actuator 42 is used to operate the switch of the switch cabinet. The other end of the actuator 42 is provided with a first slot structure 423 that cooperates with the switch. The top wall of the first slot structure 423 has an inwardly extending inclined surface 4231. The first slot structure 423 is a hexagonal slot structure. The corners of the hexagonal slot structure are corners formed by the edges of the rounded curved surfaces.
[0087] The rack assembly 1 is equipped with a first depth camera 6, which is located above the telescopic mechanism 3 and is electrically connected to the control system. The first depth camera 6 is used to collect the position information of the switch in the switchgear and then feeds it back to the control system. The control system then drives the rotary lifting mechanism 7, the transmission mechanism, and the telescopic mechanism 3 to bring the first slot structure 423 closer to the switch in the switchgear. However, slight positioning errors may occur, causing the first slot structure 423 and the switch in the switchgear to be slightly misaligned. In this case, the inclined surface 4231 of the top wall of the first slot structure 423 will help the switch slide into the first slot structure 423.
[0088] The limiting member 44 is fixed with a third sensor 442, which can sense the actuator 42. The frame assembly 1 has a receiving space containing a spring wire 14. The feed sleeve 34 is hollow, and either the feed sleeve 34 or the frame assembly 1 has a wire hole through which one end of the spring wire 14 passes. One end of the spring wire 14 is electrically connected to the third sensor 442 via the wire hole, and the other end is connected to a power source. In other embodiments, the third sensor 442 and the transmission member 41 are fixedly connected. In specific applications, the actuator 42 is a metal part, and the third sensor 442 is a sensor capable of sensing metal. When the first slot structure 423 and the switch of the switch cabinet are misaligned, the telescopic mechanism 3 drives the actuator 42 to touch the switch of the switch cabinet, subjecting it to reverse pressure. This causes the actuator 42 to slide backward relative to the transmission member 41, compressing the elastic buffer member 43. When the actuator 42 retracts to the position of the third sensor 442, the third sensor 442 senses the actuator 42. When the first slot structure 423 and the switch of the switch cabinet are engaged, the actuator 42 will suddenly return to its original position. The third sensor 442 senses the signal that the actuator 42 has left and feeds the signal back to the control system. The control system determines that the engagement of the first slot structure 423 and the switch of the switch cabinet is complete.
[0089] The transmission component 41 is equipped with an endoscope 411, and the actuator 42 is a cylindrical structure. The endoscope 411 can monitor the situation outside the actuator 42 through the cylindrical structure. The endoscope 411 is electrically connected to the control system, and the endoscope 411 and the first depth camera 6 are used to jointly monitor the position of the switch cabinet switch. The feed sleeve 34 is a hollow structure, and one end of the spring wire 14 is electrically connected to the endoscope 411 through the hollow structure, while the other end of the spring wire 14 is connected to the power supply.
[0090] In another embodiment, the actuator 4 has a centering structure. The actuator 4 includes an actuator 42, a transmission member 41, and a centering auxiliary member 9. The connection between the actuator 42 and the transmission member 41 is the same as the connection structure between the actuator 42 and the transmission member 41 described above. In this embodiment, the transmission member 41 is connected to the feed sleeve 34 via the centering auxiliary member 9, and the centering auxiliary member 9 and the feed sleeve 34 are fixedly connected. The transmission member 41 and the centering auxiliary member 9 are connected by a centering structure, which includes a universal joint structure 92, a pressure-bearing elastic member 922, and a return member between the transmission member 41 and the centering auxiliary member 9. The universal joint structure 92 includes a connecting block 921. One end of the centering auxiliary member 9 has two outwardly extending, opposing first connecting portions 91. One end of the transmission member 41 has two outwardly extending, opposing second connecting portions 412. The two first connecting portions 91 are hinged to opposite sides of the connecting block 921, and the two second connecting portions 412 are hinged to the other opposite sides of the connecting block 921, so that the transmission member 41 and the centering auxiliary member 9 are approximately in a straight line. However, due to the universal joint structure 92, the transmission member 41 can tilt relative to the centering auxiliary member 9. A pressure-bearing elastic member 922 is provided between the connecting block 921 and the transmission member 41, and between the connecting block 921 and the centering auxiliary member 9. In specific applications, the pressure-bearing elastic member 922 is a disc spring. The compressed elastic element 922 is in a compressed state, which allows the transmission element 41 to tilt relative to the centering auxiliary element 9 and then return to its original position, restoring the transmission element 41 and the centering auxiliary element 9 to a state where they are approximately in a straight line. The return element is a ball bearing 923 or a rubber pad, which is installed at the end of the first connecting part 91 and abuts against the transmission element 41. The return element is also installed at the end of the second connecting part 412 and abuts against the centering auxiliary element 9. The return element helps the transmission element 41 return to its original position after tilting relative to the centering auxiliary element 9. The universal joint structure, the clearance fit between the transmission element 41 and the actuator 42 form the bipolar floating of the actuator 4, allowing the actuator 4 to adapt to offsets of ±3° in the deflection angle and ±1mm in the eccentricity.
[0091] It also includes a robotic arm, which is mounted on a fixed chassis. A control system controls the movement of the robotic arm 1021. The robotic arm 1021 has four end-effectors at its end, all angled at the same angle relative to the robotic arm 1021.

The fixed body A31 and the first fixing member A1 are connected by bearings, and the fixed body A31 and the output shaft of the first power source A2 are connected by a transmission drive. The first power source A2 drives the first actuation component to rotate. In specific applications, the fixed body A31 is a fixed outer shell.
[0093] The clamping transmission structure includes a gear set and a threaded rod A53. The gear set includes a first gear A51 and a second gear A52.

The fixed body A31 is provided with a sliding hole A311 through which the fourth connector A41 passes, and the sliding hole A311 restricts the fourth connector A41 to only perform linear movement. The fourth connector A41 is provided with a positioning part A412, which abuts against the inner wall of the fixed body A31 to prevent the fourth connector A41 from deflecting and restricts the fourth connector A41 to only perform linear movement.

When two clamping members A4 approach each other, the semi-recessed portions A46 of the two clamping members A4 overlap to form a complete clamping hole A47. In specific applications, the clamping hole A47 is a square hole. It also includes a second depth camera A6, which is mounted on the first fixing member A1. The second depth camera A6 is mounted above the fixed body A31. The second depth camera A6 is electrically connected to the control system. The second depth camera A6 detects the position of the switch in the switch cabinet. The control system then controls the robotic arm 1021 to bring the end effector A close to the switch in the switch cabinet. The second power source A32 is then driven, causing the two grippers A4 to clamp the switch. The first power source A2 is then driven, causing the grippers A4 to rotate and turn the switch open. The click switch component A43 allows the user to click the button switch under the drive of the robotic arm 1021. The grippers A4 can hold square switches, and the gripping part A45 can also hold handle-shaped / strip-shaped switches.
[0095] The end effector B includes a second fixing member B1 mounted on the robotic arm 1021, a guide sleeve B2 fixed to the second fixing member B1, and an operating lever B3. The operating lever B3 and the guide sleeve B2 are slidably connected, and an elastic auxiliary member B4 is provided between the operating lever B3 and the guide sleeve B2.

[0097] The second fixing member B1 is fixed with a third depth camera B6, which is located above the guide sleeve B2 and is electrically connected to the control system. The third depth camera B6 detects the position of the switch in the switch cabinet. The control system then controls the robotic arm 1021 to bring the end effector B close to the switch in the switch cabinet. The operating lever B3 can click a button-type switch. When the robotic arm 1021 controls the operating lever B3 to click the switch, a pressure sensor detects the pressure on the elastic auxiliary member B4, i.e., the pressure of the operating lever B3 on the button switch. The pressure sensor transmits the pressure signal to the control system, which can determine the force with which the operating lever B3 clicks the switch based on the sensor's signal.
[0098] The end effector switch tool C includes a third fixing member C1 mounted on the robotic arm 1021, a motor C2 mounted on the third fixing member C1, and a transmission rod C3 coaxially fixedly connected to the output shaft of the motor C2.

When the operating member C4 slides to the end of the transmission rod C3, the first detachment prevention part C31 and the second detachment prevention part C43 abut against each other to prevent the operating member C4 from detaching from the transmission rod C3. The operating member C4 is a cylindrical structure, sleeved outside the transmission rod C3. The first detachment prevention part C31 is a screw fixed to the end of the transmission rod C3, the screw being larger than the size of the transmission rod C3.

The fourth depth camera C6 can detect the position of the switch in the switch cabinet and then transmit the position signal of the switch cabinet to the control system. The control system controls the robotic arm 1021 to bring the end effector C closer to the switch in the switch cabinet. The docking slot structure C42 of the manipulator C4 can engage with the square switch in the switch cabinet. When the docking slot structure C42 misaligns with the square switch, the inclined transition surface C421 helps the docking slot structure C42 to engage with the square switch. The docking slot structure C42 has eight corners, formed by two overlapping and intersecting cubes, making it easier for the square switch to enter the docking slot structure C42. The motor C2 drives the transmission rod C3 to rotate. When any corner of the docking slot structure C42 contacts any corner of the square switch, the docking slot structure C42 will quickly engage with the other parts of the square switch. Then, the motor C2 continues to rotate, causing the manipulator C4 to turn the switch open.
[0101] The end effector D includes a fourth fixing member D1 mounted on the robotic arm 1021, a power mechanism D2 mounted on the fourth fixing member D1, and a drive rod assembly connected to the output shaft of the power mechanism D2. The drive rod assembly is connected to the fourth fixing member D1 by a bearing, and a screwing component D5 is provided at the end of the drive rod assembly.

[0102] A stop structure is provided between the kit D4 and the drive rod D3 to limit the sliding position of the kit D4. The stop structure includes a first blocking part D41 on the kit D4 and a second blocking part D31 on the drive rod D3. When the kit D4 slides relative to the drive rod D3 to a fixed position, the first blocking part D41 and the second blocking part D31 abut against each other to prevent the kit D4 from disengaging from the drive rod D3. A fourth fixing member D1 is fixedly connected to a fixing sleeve D6, which is sleeved on the drive rod assembly. A bearing is provided between the drive rod assembly and the fixing sleeve D6. A stop structure is provided between the kit D4 and the fixing sleeve D6 to limit the sliding position of the kit D4. The stop structure includes a first stop part D42 on the kit D4 and a second stop part D61 on the fixing sleeve D6.

The range of motion of kit D4 is limited between the second blocking part D31 and the second blocking part D61. In specific applications, the first blocking part D41 and the first blocking part D42 are configured as a single unit.

[0104] The fifth depth camera D7 is fixed to the fourth fixing member D1 and is electrically connected to the control system. The fifth depth camera D7 is located above the drive rod D3. The fifth depth camera D7 can detect the position of the switch in the switch cabinet and then transmit the position signal of the switch cabinet to the control system. The control system controls the robotic arm 1021 to bring the end effector D5 closer to the switch in the switch cabinet. The notch D52 at the end of the end effector D5 can engage the handle-shaped / strip-shaped switch. After the switch is engaged, the power mechanism D2 is driven to make the end effector D5 turn the switch. Some switches require pressing to open after turning. In this case, the robotic arm 1021 needs to press the end effector D5, so that the end effector D5 will retract relative to the drive rod D3, and the end of the drive rod D3 will press the switch. After the switch is opened, the elastic release member D32 can return the end effector D5 to its initial position.

The connecting frame includes a second connecting member and a third connecting member. The second connecting member and the third connecting member are slidably connected. The second connecting member is drive-connected to the output shaft of the steering drive mechanism. The third connecting member is fixedly connected to the housing of the travel drive motor of the travel drive mechanism. The suspension mechanism includes a shock-absorbing elastic member disposed between the second connecting member and the third connecting member. A pre-compression structure is provided between the second connecting member and the third connecting member to compress the shock-absorbing elastic member. The pre-compression structure includes a pre-compression member disposed on one of the second connecting member and the third connecting member and a connecting part disposed on the other. The pre-compression member and the connecting part are connected. When the pre-compression member and the connecting part are connected, the shock-absorbing elastic member is in a compressed state. The rotary lifting mechanism includes a first driving component, a second driving component, a bottom nut, an upper nut, and a ball screw. The ball screw is fixed to a movable base. Both the bottom nut and the upper nut are fitted onto the ball screw. The bottom nut includes a first inner ring and a first outer ring, which are connected by a bearing. The first inner ring is fitted around the ball screw and is keyed to the ball screw. The first inner ring can only move linearly relative to the ball screw. The first inner ring is circumferentially fixed relative to the ball screw but axially relative to it. The first outer ring is fixedly connected to the frame assembly. The upper nut includes a second inner ring and a second outer ring, which are connected by bearings. The second inner ring has a thread that mates with the ball screw. The second outer ring is fixedly connected to the frame assembly. Both the first driving component and the second driving component are mounted on the frame assembly. The output shaft of the first driving component is connected to the first inner ring via a synchronous belt drive, and the output shaft of the second driving component is also connected to the second inner ring via a synchronous belt drive. A limiting structure for limiting the rotation angle of the frame assembly is provided between the frame assembly and the ball screw. The limiting structure includes a limiting member and a blocking member. The limiting member is fixed to the frame assembly, and the blocking member is directly or indirectly fixedly connected to the first inner ring or the ball screw. The blocking member has two stops, and the limiting member is limited between the two stops. The telescopic mechanism includes a drive mechanism and a lead screw telescopic mechanism located on the frame assembly. The drive mechanism is electrically connected to the control system. The drive mechanism includes a first motor, and the lead screw telescopic mechanism includes a lead screw and a feed assembly that cooperates with the lead screw. The lead screw and the frame assembly are connected by bearings. The output shaft of the first motor is equipped with a synchronous pulley, and the lead screw is fixed with the synchronous pulley. The first motor drives the lead screw to rotate through the synchronous belt and the synchronous pulley. The feed assembly and the frame assembly are slidably connected. The frame assembly includes an outer sleeve assembly, which is sleeved on the outside of the feed assembly. The feed assembly includes a feed nut and a feed sleeve, which are fixedly connected. The outer sleeve assembly and the feed sleeve are keyed together, so that the feed assembly and the outer sleeve assembly are circumferentially fixed and axially sliding. A rotary drive is provided inside the frame assembly. The rotary drive is electrically connected to the control system. The rotary drive drives the outer sleeve assembly to rotate, thereby driving the feed sleeve to rotate. The actuator is located at the end of the feed sleeve. When the frame assembly is working, the control system controls the first motor to drive the lead screw pair telescopic mechanism to extend and retract, so that the actuator approaches the switch cabinet switch that is in contact with the target operation. Then, the control system controls the rotary drive output shaft to rotate, which drives the actuator to rotate, thereby rotating and opening the switch cabinet switch. When the rotary drive rotates, it drives the feed assembly to rotate. The control system controls the lead screw to rotate in the opposite direction through the first motor, so that the feed assembly is stationary relative to the lead screw.
