Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, and in particular to an intelligent robot based on a high-precision positioning charging connector. Background Technology

[0002] Intelligent robots, as a product of the deep integration of multiple disciplines, integrate core technologies such as mechanical engineering, electronic technology, computer science, and artificial intelligence (AI). They possess the ability to autonomously or semi-autonomously perceive their environment, process information, make decisions, and execute tasks. They can effectively replace or assist humans in completing complex, tedious, highly repetitive, safety-risk, or precision-critical tasks, making them typical intelligent equipment. From the perspective of application scenarios, intelligent robots mainly encompass three categories: industrial intelligent robots, service intelligent robots, and special-purpose intelligent robots. Among them, AGVs (Automated Guided Vehicles), widely used in the transportation industry, belong to an important branch of industrial intelligent robots. These devices can autonomously drive according to preset paths or through dynamic path planning, accurately completing automated tasks such as material handling, cargo loading and unloading, and environmental inspection, providing crucial support for improving efficiency in the transportation process.

[0003] In actual operation, after working for a period of time, intelligent robots need to periodically and precisely return to a specific area of ​​the charging station to replenish their power, ensuring the continuous operation of subsequent tasks. However, the charging process for intelligent robots still has problems: when the robot enters the charging area, its charging interface often fails to align precisely with the charging station interface due to positional deviation. This misalignment not only easily causes collisions between interfaces, resulting in equipment damage, but also directly affects the safety and stability of the charging process, preventing the robot from completing power replenishment normally, thereby reducing overall operational efficiency and increasing equipment maintenance costs. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an intelligent robot based on a high-precision positioning charging connector, which solves the problems of poor safety and stability during the charging process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an intelligent robot based on a high-precision positioning charging connector, comprising: a drivable robot body, a rectangular pit set on the ground, and a support platform frame connected to the robot body. A male charging connector and a female charging connector adapted to the male charging connector are provided on the top of the robot body. The female charging connector is connected to an external charging station. The robot body also includes an end limiting baffle and a lifting horizontal push plate assembly set in the rectangular pit. After the lifting horizontal push plate assembly moves upward, it can horizontally drive the robot body to make close contact with the end limiting baffle. The top end of the robot body is provided with a rectangular mounting slot, and a longitudinal sliding component is connected in the rectangular mounting slot. A passive positioning component is connected to the longitudinal sliding component, which is suitable for driving the male charging head to move along the width direction of the robot body and correspond to the female charging head.

[0006] By adopting the above technical solution, during use, the goods are first placed on the support platform, and the robot body starts working, driving the goods to complete the transportation operation. When the intelligent robot runs for a period of time and needs to replenish its power, the robot body will actively enter the charging area, at which point one end will contact the end limit baffle. Next, the lifting horizontal push plate assembly moves upward a certain distance, and then the lifting horizontal push plate assembly drives the robot body to make fine adjustments to ensure that the robot body and the end limit baffle are tightly fitted—this action can effectively enhance the parallelism of the center lines of the charging male and charging female connectors, laying the foundation for subsequent precise docking. Finally, the longitudinal sliding assembly starts working, driving the passive positioning assembly to move; under the cooperative action of the passive positioning assembly, the charging male connector will move along the width direction of the robot body until it is precisely aligned with the charging female connector. Afterwards, the longitudinal sliding assembly continues to drive the charging male connector to move, finally achieving electrical connection with the charging female connector. The entire process can significantly reduce the distance error between the male and female charging connectors along the width of the robot body, thereby reducing the probability of damage caused by collision and further improving the safety and stability of the charging process.

[0007] In a preferred embodiment, the present invention can be further configured as follows: the lifting horizontal push plate assembly includes a rectangular plate and a strip-shaped fixing plate connected to its lower plane; a vertical electric push rod is connected to the lower end of the strip-shaped fixing plate; the tail of the vertical electric push rod is connected to the bottom of the rectangular groove; two horizontal electric push rods are connected at intervals on the strip-shaped fixing plate; a push plate body is connected between the extended ends of the horizontal electric push rods; and the push plate body is located below the rectangular plate. It also includes vertical guide members connected to the lower planes at both ends of the rectangular plate. The vertical guide members include a rectangular guide tube and a rectangular guide plate slidably connected to its inner cavity. The rectangular guide tube is fixed to the inner wall of the rectangular pit. The top of the rectangular guide plate is connected to the rectangular plate. When the vertical electric push rod drives the strip fixing plate to descend to the lowest point, the upper plane of the rectangular plate is flush with the ground.

[0008] By adopting the above technical solution, when the robot body enters the charging area, firstly, the vertical electric push rod is activated, driving the strip fixing plate and the rectangular plate to move vertically a specified distance. Then, the two horizontal electric push rods work synchronously, pushing the robot body horizontally until it achieves a tight fit with the end limit baffle. This process significantly improves the parallelism of the charging male and female connector axes, providing a crucial guarantee for stable charging. The rectangular guide plate can slide precisely inside the rectangular guide tube. On the one hand, this effectively enhances the stability of the vertical movement of the strip fixing plate and the rectangular plate driven by the vertical electric push rod, avoiding displacement deviation. On the other hand, the nested structure of the rectangular guide plate and the rectangular guide tube forms a horizontal positioning constraint on the two horizontal electric push rods, ensuring that the horizontal electric push rods can accurately drive the robot body to adjust its position, ultimately achieving reliable and tight contact between one end of the robot body and the end limit baffle.

[0009] In a preferred embodiment, the present invention can be further configured such that the end limiting baffle includes a base plate and a baffle body connected to its top, the base plate being connected to the ground by anchor bolts.

[0010] By adopting the above technical solution, the baffle body is indirectly connected to the ground through the base plate. After the baffle body is in close contact with the end of the robot body, the parallelism of the charging male and charging female axes can be increased.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the longitudinal sliding assembly includes a mounting plate and a first electric push rod connected to the mounting plate, the first electric push rod has guide rails on both sides, the mounting plate and the guide rails are both connected to the bottom of the rectangular mounting groove, and the extended end of the first electric push rod is connected to the passive positioning assembly.

[0012] By adopting the above technical solution, since the passive positioning component is connected to the guide rail, the telescopic rod of the first electric push rod extends, thereby driving the passive positioning component to move towards the external charging station.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the passive positioning component includes a rolling slide rail and an L-shaped plate connected thereto, wherein the charging male connector is installed at the center of the vertical side of the L-shaped plate, and further includes a compression positioning component connected to both ends of the vertical side of the L-shaped plate, wherein an elastic limiting component is connected between the compression positioning component and the corresponding end of the rolling slide rail.

[0014] By adopting the above technical solution, in the absence of external driving force, the use of elastic limiting components keeps the male charging connector on the L-shaped plate at the center position along the width direction of the robot body. Through the action of the squeezing positioning components at both ends of the L-shaped plate, the L-shaped plate is driven to finely adjust the male charging connector along the width direction of the robot body, ensuring that the male charging connector aligns with the female charging connector.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the rolling slide rail includes an upward-opening C-shaped steel, a rolling slider is rolledly connected at intervals inside the C-shaped steel, and a sealing plate is connected to each end of the C-shaped steel; The rolling slider includes an inverted T-shaped plate. The top of the vertical side of the T-shaped plate is connected to an L-shaped plate. Vertical fixing shafts are respectively installed at both ends of the horizontal side of the T-shaped plate. Roller bodies are respectively fitted at the upper and lower ends of the vertical fixing shafts. The roller bodies are in rolling connection with the corresponding side walls inside the C-shaped steel. An L-shaped seat is connected to one side of the T-shaped plate. A transverse fixing shaft is installed on the L-shaped seat. Roller bodies are respectively fitted at both ends of the transverse fixing shafts. The roller bodies are in rolling connection with the top and bottom walls inside the C-shaped steel.

[0016] By adopting the above technical solution, sealing plates are connected to both ends of the C-shaped steel, effectively enhancing its structural strength. Roller body one is installed at both ends of the vertical fixed shaft of the T-shaped plate, forming a rolling connection with the corresponding sidewall inside the C-shaped steel. Simultaneously, an L-shaped seat is connected to the side of the T-shaped plate, with a transverse fixed shaft passing through it. Roller body two is installed at both ends of the transverse fixed shaft, and these roller bodies roll in cooperation with the top and bottom walls inside the C-shaped steel. This double rolling connection design significantly reduces the resistance encountered by the T-shaped plate when sliding within the C-shaped steel.

[0017] In a preferred embodiment, the present invention can be further configured as follows: the extrusion-type positioning component includes a hexagonal rod, a V-shaped groove, and a first spring fitted on the outer circumference of the hexagonal rod. One end of the hexagonal rod is connected to a screw and passes through an L-shaped plate. An annular washer is fitted on the screw and a nut is screwed onto it. The other end of the hexagonal rod is connected to a circular baffle. The end of the circular baffle near the V-shaped groove is connected to a U-shaped mounting base. A positioning roller is rotatably connected inside the U-shaped mounting base. The V-shaped groove is connected to an external charging station.

[0018] By adopting the above technical solution, the longitudinal sliding component will synchronously drive the passive positioning component to move during operation. In the structure of the passive positioning component, the L-shaped plate drives the U-shaped mounting base at the end of the hexagonal rod and the positioning roller mounted on it to move synchronously through the force of the first spring. At this time, the positioning roller forms a rolling engagement with the inclined edge of the V-shaped groove. As the L-shaped plate continues to move, the positioning roller will roll along the inclined edge towards the center position of the V-shaped groove. During the rolling process of the positioning roller, a lateral force is generated along the width direction of the robot body. This force will directly drive the charging male connector on the L-shaped plate to move, ultimately achieving precise alignment with the charging female connector, thus enabling the charging male connector to automatically align with the charging female connector. In terms of structural connection, the hexagonal rod is set through the L-shaped plate, one end of which is fixedly connected to the screw, and the screw is fitted with annular washers and screwed with locking nuts; the other end of the hexagonal rod is connected to a circular baffle. This structural design not only ensures that the hexagonal rod can move freely in a direction perpendicular to the L-shaped plate, but also effectively prevents it from detaching from the L-shaped plate, significantly improving the stability and reliability of the positioning roller during its movement.

[0019] In a preferred embodiment, the present invention can be further configured such that the elastic limiting member includes a second spring, a first vertical plate and a second vertical plate connected at both ends thereto, the first vertical plate being connected to an L-shaped plate, and the second vertical plate being connected to a sealing plate at the end of a C-shaped steel.

[0020] By adopting the above technical solution, after the intelligent robot finishes charging, it separates from the external charging station. Under the elastic force of the second spring, the L-shaped plate drives the charging male head to reset, so that the charging male head moves to the center position along the width direction of the robot body.

[0021] In a preferred embodiment, this utility model can be further configured as follows: it also includes two horizontal support plates, which are embedded in the ground at intervals and are horizontally arranged. The robot body is in contact with the two horizontal support plates respectively, and the center of the male charging head and the center of the female charging head are at the same height in the vertical direction.

[0022] By adopting the above technical solution, after the intelligent robot enters the charging area, the robot body rests on a horizontal support plate, reducing the robot body's tilt angle. This ensures that the center of the male charging connector and the center of the female charging connector are at the same vertical height.

[0023] In summary, this utility model has at least one of the following beneficial technical effects: By fine-tuning the position of the lifting horizontal push plate assembly, the parallelism of the center lines of the charging male and female connectors is enhanced. With the assistance of the passive positioning component, the distance error between the charging male and female connectors along the width of the robot body is significantly reduced, achieving precise docking, reducing the probability of collisions between the charging male and female connectors due to alignment deviations, protecting components, extending service life, and improving safety and stability during the charging process.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Reference Figures 1-7 This utility model discloses an intelligent robot based on a high-precision positioning charging connector, comprising: a drivable robot body 1, a rectangular pit 2 set on the ground, and a support platform frame 3 connected to the robot body 1. A charging male connector 11 and a charging female connector 12 adapted to the charging male connector 11 are provided on the top of the robot body 1. The charging female connector 12 is connected to an external charging station. It also includes an end limiting baffle 40 and a lifting horizontal push plate assembly 50 set in the rectangular pit 2. After the lifting horizontal push plate assembly 50 moves upward, it can horizontally drive the robot body 1 to make close contact with the end limiting baffle 40.

[0035] The lifting horizontal push plate assembly 50 includes a rectangular plate 51 and a strip-shaped fixing plate 52 connected to its lower plane. A vertical electric push rod 53 is connected to the lower end of the strip-shaped fixing plate 52. The tail of the vertical electric push rod 53 is connected to the bottom of the rectangular pit 2. Two horizontal electric push rods 54 are connected at intervals on the strip-shaped fixing plate 52. A push plate body 55 is connected between the extended ends of the horizontal electric push rods 54. The push plate body 55 is located below the rectangular plate 51. It also includes vertical guide members 56 connected to the lower planes of both ends of the rectangular plate 51. The vertical guide member 56 includes a rectangular guide tube 561 and a rectangular guide plate 562 slidably connected to its inner cavity. The rectangular guide tube 561 is fixed to the inner wall of the rectangular pit 2. The top of the rectangular guide plate 562 is connected to the rectangular plate 51. When the vertical electric push rod 53 drives the strip-shaped fixing plate 52 to descend to the lowest position, the upper plane of the rectangular plate 51 is flush with the ground. When the robot body 1 enters the charging area, firstly, the vertical electric push rod 53 is activated, driving the strip fixing plate 52 and the rectangular plate 51 to move vertically a specified distance. Then, the two horizontal electric push rods 54 work synchronously, pushing the robot body 1 to move horizontally until it is tightly fitted with the end limiting baffle 40. This process significantly improves the parallelism of the charging male connector 11 and the charging female connector 12, providing crucial assurance for stable charging. The rectangular guide plate 562 can slide precisely inside the rectangular guide tube 561. On the one hand, this effectively enhances the stability of the vertical movement of the strip fixing plate 52 and the rectangular plate 51 driven by the vertical electric push rod 53, avoiding displacement deviation. On the other hand, the nested structure of the rectangular guide plate 562 and the rectangular guide tube 561 forms a horizontal positioning constraint on the two horizontal electric push rods 54, ensuring that the horizontal electric push rods 54 can accurately drive the robot body 1 to adjust its position, ultimately achieving reliable and tight contact between one end of the robot body 1 and the end limiting baffle 40.

[0036] The end limiting baffle 40 includes a base plate 41 and a baffle body 42 connected to its top. The base plate 41 is connected to the ground by anchor bolts. The baffle body 42 is indirectly connected to the ground through the base plate 41. After the baffle body 42 is in close contact with the end of the robot body 1, it can increase the parallelism of the axes of the charging male connector 11 and the charging female connector 12.

[0037] A rectangular mounting slot 13 is provided at one top end of the robot body 1. A longitudinal sliding component 60 is connected inside the rectangular mounting slot 13. A passive positioning component 70 is connected to the longitudinal sliding component 60, which is suitable for driving the charging male connector 11 to move along the width direction of the robot body 1 and correspond to the charging female connector 12.

[0038] The longitudinal sliding assembly 60 includes a mounting plate 61 and a first electric push rod 62 connected to the mounting plate 61. Guide rails 63 are respectively provided on both sides of the first electric push rod 62. Both the mounting plate 61 and the guide rails 63 are connected to the bottom of the rectangular mounting groove 13. The extended end of the first electric push rod 62 is connected to the passive positioning assembly 70. Because the passive positioning assembly 70 is connected to the guide rails 63, the telescopic rod of the first electric push rod 62 extends, thereby driving the passive positioning assembly 70 to move towards the external charging station.

[0039] The passive positioning assembly 70 includes a rolling slide rail 71 and an L-shaped plate 72 connected thereto. The charging male connector 11 is mounted at the center of the vertical side of the L-shaped plate 72. It also includes compression positioning members 73 connected to both ends of the vertical side of the L-shaped plate 72. Each compression positioning member 73 is connected to an elastic limiting member 74 at its corresponding end of the rolling slide rail 71. Without external driving force, the elastic limiting member 74 keeps the charging male connector 11 on the L-shaped plate 72 at its center along the width direction of the robot body 1. Through the action of the compression positioning members 73 at both ends of the L-shaped plate 72, the L-shaped plate 72 is driven to finely adjust the charging male connector 11 along the width direction of the robot body 1, aligning the charging male connector 11 with the charging female connector 12.

[0040] The rolling slide rail component 71 includes an upward-opening C-shaped steel 711, with rolling sliders 712 connected at intervals inside the C-shaped steel 711. Sealing plates 713 are connected to both ends of the C-shaped steel 711. The rolling sliders 712 include an inverted T-shaped plate 7121. The top of the vertical side of the T-shaped plate 7121 is connected to an L-shaped plate 72. Vertical fixing shafts 7122 are respectively installed at both ends of the horizontal side of the T-shaped plate 7121. Roller bodies 7123 are respectively fitted onto the upper and lower ends of the vertical fixing shafts 7122. Roller bodies 7123 are tactilely connected to the corresponding side walls inside the C-shaped steel 711. An L-shaped seat 7124 is connected to one side of the T-shaped plate 7121. A transverse fixing shaft 7125 is installed on the L-shaped seat 7124. Roller bodies 7126 are respectively fitted onto both ends of the transverse fixing shaft 7125. Roller bodies 7126 are tactilely connected to the top and bottom walls inside the C-shaped steel 711. The C-shaped steel 711 is connected to end plates 713 at both ends, effectively enhancing its structural strength. Roller bodies 7123 are installed at both ends of the vertical fixed shaft 7122 of the T-shaped plate 7121, forming a rolling connection with the corresponding sidewall inside the C-shaped steel 711. Simultaneously, an L-shaped seat 7124 is connected to the side of the T-shaped plate 7121, with a transverse fixed shaft 7125 passing through it. Roller bodies 7126 are installed at both ends of the transverse fixed shaft 7125, and these roller bodies 7126 roll in cooperation with the top and bottom walls inside the C-shaped steel 711. This double rolling connection design significantly reduces the resistance encountered by the T-shaped plate 7121 when sliding within the C-shaped steel 711.

[0041] The extrusion-type positioning component 73 includes a hexagonal rod 731, a V-shaped groove 732, and a first spring 733 fitted around the outer circumference of the hexagonal rod 731. One end of the hexagonal rod 731 is connected to a screw 734 that passes through an L-shaped plate 72. An annular washer 735 is fitted onto the screw 734 and a nut is screwed onto it. The other end of the hexagonal rod 731 is connected to a circular baffle 736. A U-shaped mounting base 737 is connected to the end of the circular baffle 736 near the V-shaped groove 732. A positioning roller 738 is rotatably connected inside the U-shaped mounting base 737. The V-shaped groove 732 is connected to an external charging station. When the longitudinal sliding assembly 60 is running, it will synchronously drive the passive positioning assembly 70 to move. In the structure of the passive positioning assembly 70, the L-shaped plate 72, through the force of the first spring 733, drives the U-shaped mounting base 737 at the end of the hexagonal rod 731 and the positioning roller 738 mounted thereon to move synchronously. At this time, the positioning roller 738 and the inclined edge of the V-shaped groove 732 form a rolling engagement. As the L-shaped plate 72 continues to move, the positioning roller 738 will roll along the inclined edge towards the center position of the V-shaped groove 732. During the rolling process of the positioning roller 738, a lateral force will be generated along the width direction of the robot body 1. This force will directly drive the charging male connector 11 on the L-shaped plate 72 to move, ultimately achieving precise alignment with the charging female connector 12, thus enabling the charging male connector 11 to automatically align with the charging female connector 12. In terms of structural connection, the hexagonal rod 731 is set through the L-shaped plate 72, one end of which is fixedly connected to the screw 734, and the screw 734 is sequentially fitted with annular washers 735 and screwed with locking nuts; the other end of the hexagonal rod 731 is connected to the circular baffle 736. This structural design not only ensures that the hexagonal rod 731 can move freely in a direction perpendicular to the L-shaped plate 72, but also effectively prevents it from detaching from the L-shaped plate 72, significantly improving the stability and reliability of the positioning roller 738 during its movement.

[0042] The elastic limiting member 74 includes a second spring 741, a first vertical plate 742 and a second vertical plate 743 connected to its two ends. The first vertical plate 742 is connected to the L-shaped plate 72, and the second vertical plate 743 is connected to the sealing plate 713 at the end of the C-shaped steel 711. After the intelligent robot finishes charging, it separates from the external charging station. Under the elastic force of the second spring 741, the L-shaped plate 72 drives the charging male connector 11 to reset, causing the charging male connector 11 to move to the center position along the width direction of the robot body 1.

[0043] It also includes two horizontal support plates 14, which are spaced apart and horizontally embedded in the ground. The robot body 1 contacts the two horizontal support plates 14 respectively, and the center of the male charging connector 11 and the center of the female charging connector 12 are at the same vertical height. After the intelligent robot enters the charging area, the robot body 1 rests on the horizontal support plates 14, reducing the tilt angle of the robot body 1. This ensures that the center of the male charging connector 11 and the center of the female charging connector 12 are at the same vertical height.

[0044] The implementation principle of this embodiment is as follows: During use, the goods are first placed on the support platform 3, and the robot body 1 starts working, driving the goods to complete the transportation operation. When the intelligent robot runs for a period of time and needs to replenish its power, the robot body 1 will actively enter the charging area, at which point one end will contact the end-limiting baffle 40. Next, the lifting horizontal push plate assembly 50 is moved upwards a certain distance, and then the lifting horizontal push plate assembly 50 will drive the robot body 1 to make fine adjustments to its position, ensuring that the robot body 1 and the end-limiting baffle 40 are tightly fitted—this action effectively enhances the parallelism of the center lines of the charging male connector 11 and the charging female connector 12, laying the foundation for subsequent precise docking. Finally, the longitudinal sliding assembly 60 starts working, driving the passive positioning assembly 70 to move; under the cooperative action of the passive positioning assembly 70, the charging male connector 11 will move along the width direction of the robot body 1 until it is precisely aligned with the charging female connector 12. Afterwards, the longitudinal sliding assembly 60 continues to drive the charging male connector 11 to move, ultimately achieving electrical connection with the charging female connector 12. The entire process can significantly reduce the distance error between the male charging head 11 and the female charging head 12 along the width direction of the robot body 1, thereby reducing the probability of damage caused by collision and further improving the safety and stability of the charging process.
