[0002] With the widespread application of intelligent inspection technology in fields such as power, petrochemicals, and rail transportation, the automation level of inspection robot charging devices has become a key factor restricting the improvement of operation and maintenance efficiency. Currently, most inspection robot charging devices adopt a design combining a fixed charging base and a limiting mechanism, using mechanical constraints to limit battery position and improve charging contact accuracy. However, the passive positioning system composed of a fixed charging base and a rigid limiting mechanism can only constrain the planar position of the robot's charging interface through physical slots. Due to the lack of active adjustment capability, manual intervention is required to manually place the inspection robot onto the charging device for manual reset. This prevents the full automation of the inspection robot's unloading, return positioning, and charging management processes, thus limiting the robot's continuous operation capability and efficiency.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1 to 5This embodiment provides a charging device for an inspection robot, including a base plate 1, a sliding assembly 2, a rotating assembly 3, a support plate 4, and a control unit. The sliding assembly 2 is disposed on the base plate 1 and includes a first drive unit 21 and a lead screw assembly 22. The first drive unit 21 is drivenly connected to the lead screw assembly 22, and the lead screw assembly 22 has a first movable end that can move relative to the base plate 1. The rotating assembly 3 is disposed on the first movable end and includes a second drive unit 31 and a connecting rod assembly 32. The second drive unit 31 is drivenly connected to the connecting rod assembly 32, and the connecting rod assembly 32 has a second movable end that can rotate relative to the first movable end. The support plate 4 is located at the second moving end. The support plate 4 is equipped with a first sensor 41, a second sensor 42, a baffle 43, and a wireless charging coil 44. The first sensor 41 is located in the circumferential direction of the support plate 4, and the second sensor 42 is located on the linkage group 32. The second sensor 42 is used to collect image information of the inspection robot, and the first sensor 41 is used to detect the inspection robot. The baffle 43 is located on the support plate 4 in a preset manner, and the wireless charging coil 44 is located in the middle of the support plate 4. The control unit is electrically connected to the first drive unit 21, the second drive unit 31, the first sensor 41, the second sensor 42, and the wireless charging coil 44.

[0046] In this embodiment, the base plate 1 serves as the main support platform for the inspection robot, supporting the entire structure and effectively supporting the weight of the entire device while adapting to complex working environments. Furthermore, the base plate 1 includes slide rails 11 extending along its length and symmetrically arranged on it, determining the direction of movement of the support plate 4, improving the stability of the mechanism's movement, and preventing deviation or swaying. The surface of the base plate 1 is precision-machined to ensure its flatness and stability, providing a solid foundation for the installation of the sliding assembly 2 and the rotating assembly 3.

[0047] The sliding assembly 2 and the rotating assembly 3 are preferably made of high-quality stainless steel, which has excellent mechanical strength and wear resistance, and can withstand frequent mechanical movements and high-load working conditions. The sliding assembly 2 includes a first drive unit 21 and a lead screw assembly 22. The lead screw assembly 22 converts the rotational motion of the first drive unit 21 into linear motion, pushing the entire structure forward to help the inspection robot dismount. The first drive unit 21 is fixed on the base plate 1 and provides rotational force to the lead screw assembly 22, which is the main power source for the sliding assembly 2.

[0048] The rotating assembly 3 drives the linkage group 32 to swing through the second drive unit 31, thus smoothly placing the inspection robot on the ground. The entire structure uses the lead screw nut 222 as the frame, and the second drive unit 31 provides power, which drives the support plate 4 to move up and down through the linkage group 32.

[0049] The support plate 4 carries the first sensor 41 and the wireless charging coil 44, sensing whether the inspection robot has returned to the vehicle and initiating wireless charging. The support plate 4 effectively supports the weight of the inspection robot and its related equipment. Its surface is treated with an anti-slip coating to ensure the inspection robot remains stable on the support plate 4, maintaining safety even during movement. Furthermore, the support plate 4 integrates a sensor interface and a connection point for the wireless charging coil 44. The sensor interface connects to the first sensor 41 to monitor the inspection robot's position and attitude in real time; the connection point for the wireless charging coil 44 ensures that once the inspection robot returns to the support plate 4, it automatically detects its position and initiates wireless charging without manual intervention, further enhancing the system's automation level.

[0050] The baffle 43 is a safety protection component of the support plate 4. It is installed in the middle of the support plate 4 according to the size of the inspection robot to prevent the inspection robot from accidentally slipping off.

[0051] The wireless charging coil 44 provides efficient and convenient charging for the inspection robot. Utilizing advanced wireless charging technology, it can charge the robot when it returns to the support plate 4, without human intervention. The use of the wireless charging coil 44 takes into account both charging efficiency and safety, ensuring that the charging process will not damage the inspection robot or other equipment.

[0052] The control unit not only regulates the first drive unit 21 and the second drive unit 31, but also integrates management functions for the wireless charging coil 44, ensuring that the system can flexibly adjust parameters according to actual production needs, thereby improving the system's adaptability and efficiency. This device utilizes multiple sensors, including the first sensor 41 and the second sensor 42, to ensure the safety and accuracy of the inspection robot during unloading and charging. These sensors provide real-time data, enabling the system to accurately determine the robot's position. Based on this, the control unit automatically controls the start and stop of the motor and the wireless charging coil 44, thereby enhancing the automation level and reliability of the entire device. Furthermore, this device also includes safety protection devices, such as limit switches and an emergency stop button, to ensure safety during the inspection robot's unloading and charging processes. The limit switches detect the movement position of the support plate 4; once a preset limit position is reached, the power source is automatically cut off to prevent damage caused by excessive movement of the mechanism. The emergency stop button allows for immediate cessation of all movement in emergency situations, ensuring the safety of the operator and the inspection robot.

[0053] During installation, the support plate 4 is fixed to the sliding assembly 2 and the rotating assembly 3 using high-precision connectors to ensure coordinated operation between the components. The first sensor 41 is installed at the edge of the support plate 4, enabling comprehensive monitoring of the inspection robot's movement. The wireless charging coil 44 is embedded inside the support plate 4, precisely docking with the inspection robot's charging receiver to ensure charging efficiency and safety.

[0054] During the installation and commissioning of the entire system, it is necessary to ensure that the connection between the base plate 1, sliding component 2, rotating component 3, and bearing plate 4 is stable and that all functional modules work together. The parameters of the first drive unit 21, the second drive unit 31, and the wireless charging coil 44 are precisely set by the control unit, and multiple adjustments are made in conjunction with the sensor feedback system to ensure that the system can stably and efficiently complete the unloading, return, and charging tasks of the inspection robot in actual operation. This not only improves the system's reliability and durability but also further enhances its automation level and practicality.

[0055] Specifically, the working principle of this device can be understood as follows: When the inspection robot needs to disembark, the control unit receives the instruction and starts the first drive unit 21. The first drive unit 21 drives the lead screw assembly 22 through the coupling, converting the rotational motion into linear motion, and pushing the carrier plate 4 to move smoothly forward along the slide rail 11 to the preset disembarkation position. Subsequently, the rotating component 3 starts to move, and the second drive unit 31 drives the linkage assembly 32 to swing, so that the carrier plate 4 slowly descends and smoothly places the inspection robot on the ground. At the same time, the first sensor 41 and the second sensor 42 monitor the position and posture of the inspection robot in real time to ensure that the disembarkation process is safe and error-free.

[0056] When the inspection robot completes its task and returns, the first sensor 41 and the second sensor 42 detect that the inspection robot is close to the charging device. The control unit automatically starts the first drive unit 21, and adjusts the carrier plate 4 to the receiving position through the lead screw assembly 22. After the inspection robot fully enters the carrier plate 4 and reaches the designated position, the control unit starts the wireless charging coil 44 to charge it. During the charging process, the sensors monitor the charging status and the position of the inspection robot in real time. If any abnormality occurs, charging will stop immediately and an alarm will be issued. After charging is completed, the control unit automatically stops the wireless charging coil 44, and the system enters a low-power standby state, waiting for the next task instruction. Throughout the process, the limit switch detects the movement range of the carrier plate 4 in real time to prevent excessive movement from causing damage to the mechanism. The emergency stop button will immediately stop all movement in an emergency to ensure the safety of equipment and personnel. This realizes the full automation of the inspection robot's disembarkation, return, and charging process, significantly improving work efficiency, reducing manual intervention, and ensuring the stability and safety of system operation.

[0057] In this embodiment, the base plate 1 ensures that the sliding component 2 moves smoothly along the preset direction through the slide rail 11, avoiding deviation. The sliding component 2 and the rotating component 3 achieve high-precision control of the linear movement and rotational descent of the support plate 4, adapting to high-load working environments. The preset baffle 43 of the support plate 4 effectively prevents the inspection robot from slipping. Its integrated first sensor 41 and the second sensor 42 on the linkage group 32 work together to detect the robot's position and posture, and adjust the movement path in real time with the control unit. The wireless charging coil 44 is precisely connected to the sensor interface to realize automatic charging start and stop. The limit switch and emergency stop button constitute multiple safety protections, limiting the movement range and supporting emergency braking. All components work together through high-precision connectors. Combined with the centralized control of the drive mechanism, sensors and charging module by the control unit, the entire process of inspection robot unloading, return positioning and charging management is automated, significantly improving operational stability and safety and reducing the need for manual intervention.

[0058] In some embodiments, there are two lead screw assemblies 22, which are arranged opposite to each other on the base plate 1. Each lead screw assembly 22 includes a lead screw 221 and a lead screw nut 222. The lead screw 221 is arranged on the base plate 1 and can rotate relative to the base plate 1. The lead screw 221 is connected to the output end of the first drive unit 21 via a coupling. The lead screw nut 222 is sleeved on the lead screw 221 and has a first movable end.

[0059] In this embodiment, the lead screw 221 is connected to the first drive unit 21 via a coupling. Its engagement with the lead screw nut 222 converts the rotation of the first drive unit 21 into linear motion of the structure, propelling the support plate 4 smoothly along the slide rail 11. The lead screw nut 222 combines a traditional nut and slider, allowing it to function as a nut connected to the lead screw 221, a slider connected to the slide rail 11, and also as the frame of the rotating assembly 3. Furthermore, the sliding assembly 2 also includes a support base 23, located at the end of the lead screw 221 furthest from the first drive unit 21 and connected to the lead screw 221. This further provides support for the support plate 4 and prevents the support plate 4 from colliding with the base plate 1 during descent, thus preventing damage to the mechanism.

[0060] This embodiment improves the stability and load capacity of the linear movement of the support plate 4 through the double lead screw 221 structure, avoiding unilateral deviation. The lead screw 221 and lead screw nut 222 work together to convert rotational motion into linear motion, driving the first moving end to move smoothly along the slide rail 11. The lead screw nut 222 integrates the functions of the nut, slider, and rotating component 3 frame, simplifying the structure and improving transmission efficiency. The support seat 23 at the end of the lead screw 221 provides additional support for the support plate 4, preventing damage from collision with the base plate 1 during descent and enhancing the safety of the mechanism. The overall structure, through the symmetrical layout and functional integration of the double lead screw group 22, achieves high-precision linear drive of the support plate 4 and stable connection of the rotating component 3, ensuring the reliability and mechanical durability of the inspection robot during unloading and charging.

[0061] In some embodiments, there are two linkage groups 32, with one linkage group 32 disposed on a first movable end; each linkage group 32 includes a first support rod 321, a third drive unit, and a second support rod 322. One end of the first support rod 321 is drivenly connected to the second drive unit 31, and the second drive unit 31 is used to adjust the angle of the first support rod 321 relative to the lead screw 221. The other end of the first support rod 321 extends outward; the third drive unit is disposed at the other end of the first support rod 321; one end of the second support rod 322 is drivenly connected to the third drive unit, and the other end of the second support rod 322 is provided with a second movable end.

[0062] In this embodiment, the rotating assembly 3 drives the linkage group 32 to swing via the second drive unit 31, smoothly placing the inspection robot on the ground. Specifically, the rotating assembly 3 drives the first support rod 321 to swing via the second drive unit 31, and drives the second support rod 322 to swing via the third drive unit, enabling the carrier plate 4 to rise and fall smoothly, ensuring the safety of the inspection robot during disembarkation and return. The entire structure uses the lead screw nut 222 as the frame, with the second drive unit 31 providing power, driving the carrier plate 4 to move up and down via the linkage group 32.

[0063] In this embodiment, the two linkage groups 32 are respectively set on the first moving end. The angle of the first support rod 321 relative to the lead screw 221 is adjusted by the second drive unit 31, and the second support rod 322 is driven to swing by the third drive unit, forming a two-stage transmission structure to achieve precise control of the lifting path of the bearing plate 4. Through the coordinated action of the two linkage groups 32 and the drive unit, the bearing plate 4 is ensured to rise and fall smoothly when the inspection robot gets off and returns, avoiding tilting or shaking. The lead screw nut 222 serves as a frame to fix the second drive unit 31, enhancing structural stability. At the same time, the extended layout of the support rod optimizes the transmission efficiency. By adjusting the angle and swing amplitude of the first support rod 321 and the second support rod 322 step by step by the dual drive units of the second drive unit 31 and the third drive unit, the coordination and controllability of the mechanical action are improved, ensuring the safety of the inspection robot during movement and further enhancing the reliability and durability of the device.

[0064] In some embodiments, the second drive unit 31 and the third drive unit are servo motors or servo motors; the first drive unit 21 is a servo motor.

[0065] In this embodiment, the second drive unit 31 and the third drive unit employ servo motors or servo motors, which, combined with the servo motor of the first drive unit 21, form a high-precision drive system. Specifically, the servo motor in the first drive unit 21 ensures precise linear motion control of the lead screw assembly 22, while the servo motors or servo motors in the second and third drive units enable rapid response in the angle adjustment and swinging of the linkage assembly 32. Each drive unit works collaboratively; the second drive unit 31 precisely adjusts the angle of the first support rod 321, and the third drive unit accurately drives the second support rod 322 to swing, improving the lifting stability and motion coordination of the support plate 4, avoiding mechanical impact, and ensuring the safety and operational reliability of the inspection robot during its unloading and return processes.

[0066] In some embodiments, the inspection robot charging device further includes a support beam 323 disposed between two second support rods 322, and a second sensor 42 is provided on the support beam 323.

[0067] In this embodiment, in order to maintain the stability of the bearing plate 4, a support beam 323 is welded between the two second support rods 322 to keep the two second support rods 322 relatively stationary, thereby ensuring that the bearing plate 4 will not shake.

[0068] A second sensor 42 is installed on the support beam 323. In conjunction with the first sensor 41, it can determine whether the inspection robot has returned to the vehicle and determine the robot's location. When the inspection robot appears in the field of view of the second sensor 42, the charging device switches from standby mode to start mode, saving power and increasing its range.

[0069] In this embodiment, the support beam 323 is welded and fixed between two second support rods 322, eliminating the relative displacement of the second support rods 322, maintaining the structural stability of the support plate 4, and avoiding swaying caused by the swinging of the support rods during lifting. The second sensor 42 installed on the support beam 323 works in conjunction with the first sensor 41 to monitor the appearance status of the inspection robot in the image of the second sensor 42, accurately determining whether it has returned to the support plate 4, thereby triggering the charging device to switch from standby mode to start mode, reducing unnecessary energy consumption and extending the device's endurance. Through the dual-sensor linkage mechanism of the second sensor 42 and the first sensor 41 combined with the rigid connection structure of the support beam 323, while ensuring the stable operation of the support plate 4, the position detection of the inspection robot and the charging process are automated, improving the device's response efficiency and energy utilization, and ensuring the safety and reliability of the interaction process between the inspection robot and the charging device.

[0070] In some embodiments, the linkage 32 further includes a rib 324 disposed at the connection between the second support rod 322 and the bearing plate 4.

[0071] In this embodiment, the rib plate 324 is disposed at the connection between the second support rod 322 and the bearing plate 4. By strengthening the rigidity of the connection structure, the stress transmitted to the second support rod 322 during the lifting and lowering of the bearing plate 4 is dispersed, thereby improving the load-bearing capacity and fatigue resistance of the connection and avoiding the risk of deformation or breakage of the connection due to long-term stress. The rib plate 324, the second support rod 322 and the bearing plate 4 form a stable triangular support structure, further limiting the movement allowance of the connection, reducing the local vibration caused by mechanical transmission when the bearing plate 4 is lifted and lowered, enhancing the overall structural stability, ensuring that the bearing plate 4 moves smoothly and reliably during the movement and charging of the inspection robot, and extending the service life of the device.

[0072] In some embodiments, the second sensor 42 is a camera.

[0073] In this embodiment, the second sensor 42 is a camera. By capturing the real-time image of the inspection robot and coordinating with the first sensor 41 for positioning, it accurately determines whether the robot returns to the carrier plate 4, triggering the charging device to switch from standby mode to start-up mode, reducing unnecessary energy consumption and extending the device's battery life.

[0074] In some embodiments, the wireless charging coil 44 is disposed near the rear center of the carrier plate 4.

[0075] In this embodiment, the wireless charging coil 44 is an important component of the charging device. It is located above the support plate 4, near the middle and rear of the support plate 4, and is installed inside the support plate 4. It can be disassembled and installed from below the support plate 4.

[0076] In this embodiment, the wireless charging coil 44 is positioned near the rear of the support plate 4, matching the center of gravity distribution of the inspection robot's docking position, thereby improving charging alignment accuracy and energy transmission efficiency. The coil is built into the upper part of the support plate 4 and can be installed and removed from below, which avoids external structural interference with the robot's movement and facilitates quick disassembly and replacement during maintenance, taking into account both structural stability and ease of operation.

[0077] In some embodiments, the first sensor 41 is an infrared sensor, and there are four first sensors 41. Two first sensors 41 are spaced apart on one side of the support plate 4, and the other two first sensors 41 are spaced apart on the other side of the support plate 4.

[0078] In this embodiment, the first sensor 41 is used to accurately detect whether the inspection robot has returned to the carrier plate 4. It senses the position via infrared signals, triggers wireless charging, and provides status feedback. It possesses high sensitivity and anti-interference capabilities, ensuring automated and safe system operation.

[0079] In this embodiment, the four first sensors 41 are infrared sensors located on both sides of the support plate 4 and arranged at intervals to expand the detection coverage and accurately identify whether the inspection robot has completely entered the support plate 4. The position is determined by the coordinated infrared signals from both sides, which can reliably trigger wireless charging and provide real-time feedback on the robot's status. The high sensitivity and anti-interference capability ensure the detection stability in complex environments and improve the system's automated operation efficiency and charging safety.

[0080] In some embodiments, the support plate 4 is made of a lightweight material, including one of aluminum alloy, magnesium alloy, titanium alloy, carbon fiber composite material, glass fiber reinforced plastic, polyamide, and polycarbonate.

[0081] In this embodiment, the support plate 4 is made of lightweight and sturdy materials, balancing protection and convenience to ensure the stability and safety of the inspection robot during movement. It prevents the inspection robot from accidentally slipping off without adding excessive weight, while simultaneously improving the portability and efficiency of the support plate 4.

[0083] This invention provides a charging device for an inspection robot, comprising a base plate 1, a sliding assembly 2, a rotating assembly 3, a support plate 4, and a control unit. Through the coordinated operation of the automated drive assembly and the intelligent control unit, the charging efficiency and operational safety of the inspection robot are significantly improved. The sliding assembly 2 adopts a double lead screw assembly 22 linkage structure. The first drive unit 21 precisely controls the horizontal displacement of the support plate 4. Combined with the multi-directionally adjustable linkage assembly 32 in the rotating assembly 3, the second drive unit 31 and the third drive unit achieve adaptive angle adjustment of the support plate 4, enabling the wireless charging coil 44 to quickly align with the inspection robot. The integrated sensing system uses circumferentially distributed first sensors 41 on the support plate 4 to monitor the robot's position boundary in real time. Combined with the second sensors 42 on the linkage assembly 32, image acquisition forms dual positioning feedback, effectively avoiding the risk of mechanical interference. The control unit dynamically coordinates the action parameters of the first drive unit 21, the second drive unit 31, and the third drive unit based on sensor data, ensuring both equipment operational stability and adaptability to different working conditions.
