Description

Technical Field

[0001] This utility model relates to the field of charging compartment technology, and in particular to a charging compartment for an intelligent robot. Background Technology

[0002] With the rapid development of intelligent manufacturing and automation technologies, intelligent robots are widely used in various fields such as industrial production, logistics and transportation, and home services. As a key infrastructure to ensure the continuous operation of intelligent robots, the reliability and safety of charging stations are becoming increasingly important.

[0003] Existing intelligent robot charging compartments generally face technical bottlenecks in terms of protection for charging contacts and charging areas. On the one hand, charging contacts are exposed to the external environment for a long time, making them susceptible to corrosion from pollutants such as dust, debris, and moisture, which can lead to increased contact resistance, reduced charging efficiency, and even short circuits and other safety hazards. On the other hand, traditional charging compartments lack effective protection mechanisms. When encountering situations such as water seepage or accidental splashes, they cannot reliably isolate the charging area, which greatly affects the stability and safety of the charging process. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a charging compartment for an intelligent robot.

[0005] The technical solution is as follows: A charging compartment for an intelligent robot includes a charging compartment, a base plate, a servo motor, a second screw, a lifting frame, and a protective frame. The bottom of the charging compartment is integrally formed and connected to the base plate. Charging contacts are mounted on the base plate and are connected to the power lines inside the charging compartment. A servo motor is installed in the middle of the front side of the charging compartment. A second screw is connected to the output shaft of the servo motor. A lifting frame is threaded onto the second screw. The lifting frame is close to the opening of the charging compartment. A protective frame is connected to the bottom of the lifting frame and contacts the top of the base plate. The servo motor is connected to the control system of the charging compartment through electrical circuits.

[0006] As an improvement to the above solution, it also includes a sliding frame, a return spring, and a cleaning brush. The sliding frame is slidably connected to the front side of the base plate, and return springs are connected between the left and right sides of the sliding frame and the inside of the base plate. The cleaning brush is connected to the sliding frame, and the bristles of the cleaning brush are in close contact with the top surface of the base plate.

[0007] As an improvement to the above solution, the cleaning brush is made of wear-resistant and anti-static bristles.

[0008] As an improvement to the above solution, it also includes a base, a dual-axis motor, a first screw, a sliding block, and a connecting frame. The dual-axis motor is installed on the lower rear side of the charging compartment, and its two output shafts are connected to the first screw. The first screw is rotatably connected to the inside of the charging compartment. The first screw is threadedly connected to the sliding block, which is slidably connected to the inside of the charging compartment. The base is slidably connected to the bottom of the charging compartment, and the connecting frame is symmetrically connected to the rear side of the base. The connecting frame is slidably connected to the inside of the charging compartment, and its inner surface is machined into a 45° bevel to contact and cooperate with the sliding block. The dual-axis motor is connected to the control system of the charging compartment through electrical circuits.

[0009] As an improvement to the above solution, an anti-slip and shock-absorbing pad is provided at the bottom of the base.

[0010] As an improvement to the above solution, it also includes a rotating frame and a torsion spring. The left and right sides of the front side of the base plate are respectively provided with slots, and the rotating frame is rotatably connected to each slot. The rotating frame is distributed in an arc shape. A torsion spring is connected between the rotating frame and the inside of the base plate. The torsion spring is in a deformed state, and the base abuts against the rotating frame.

[0011] The present invention has the following advantages: 1. The protective frame closes the charging area when not charging, preventing the charging contacts from getting dusty or dirty; the sliding block and the connecting frame work together to raise the charging compartment as a whole during charging, effectively isolating water from the ground. The dual protection mechanism significantly improves the safety of the charging process and reduces the risk of electrical failure.

[0012] 2. When the robot enters or exits the charging compartment, the sliding frame drives the cleaning brush to automatically clean the bottom plate and the surface of the charging contacts. Through two cleaning operations, dust and foreign objects are removed to ensure that the charging contacts are in close contact and to ensure the stability and efficiency of the charging connection.

[0013] 3. The rotating frame and torsion spring are designed to automatically stand up and lock the robot's position when the charging compartment is raised, preventing the robot from shifting due to external forces during charging and ensuring continuous and reliable contact of the charging contacts.

Detailed Implementation

[0019] Example: A charging case for an intelligent robot, such as Figure 1 As shown, the system includes a charging chamber 1, a base plate 2, a servo motor 13, a second screw 14, a lifting frame 15, and a protective frame 16. The bottom of the charging chamber 1 is integrally formed and connected to the base plate 2. The base plate 2 is equipped with charging contacts, which are connected to the power lines inside the charging chamber 1. When the robot stops, the charging contacts at the bottom of the robot make close contact with the charging contacts on the base plate 2, forming a closed circuit. Current flows from the charging chamber 1 through the contacts into the robot battery, thus completing the charging process. The servo motor 13 is installed in the middle of the front side of the charging chamber 1 by screws. The output shaft of the servo motor 13 is connected to the second screw 14, and the lifting frame 15 is threaded onto the second screw 14. The lifting frame 15 is close to the opening of the charging chamber 1, and the bottom of the lifting frame 15 is connected to the protective frame 16. The protective frame 16 contacts the top of the base plate 2 and is used to protect the charging contacts on the base plate 2, ensuring the sealing of the charging area. The servo motor 13 is connected to the control system of the charging chamber 1 through electrical lines.

[0020] When the robot's power detection module detects that the battery level is below a preset threshold (e.g., less than 20% remaining), it triggers a return-to-base charging command. The robot uses a visual sensor to collect environmental information and, combined with a pre-built environmental map, plans the optimal path back to charging compartment 1 using a path planning algorithm. During its journey, it uses a navigation algorithm to detect and avoid obstacles in real time as it moves towards charging compartment 1. Simultaneously, after receiving the robot's return-to-base signal, the control system of charging compartment 1 controls the servo motor 13 to operate. The servo motor 13 drives the second screw 14 to rotate, which, through threaded transmission, moves the lifting frame 15 and the protective frame 16 upwards, ensuring that the protective frame 16 no longer obstructs the charging area. When the robot arrives near charging compartment 1, it precisely aligns with the charging contacts on the base plate 2 using a visual recognition system and uses a magnetic attraction device to achieve a stable stop, ensuring tight contact between the charging contacts and completing the electrical connection. Charging compartment 1 then begins supplying power to the robot. When the robot's power detection module detects that the battery level has reached full charge (e.g., 100%), the robot automatically disconnects from the charging compartment 1 and exits charging mode. Afterwards, the robot can choose to remain in place or return to the location where the task was interrupted to continue working, according to the preset program. When the robot leaves the charging chamber 1, the control system of the charging chamber 1 controls the servo motor 13 to rotate in reverse, driving the second screw 14 to rotate in reverse. Through the threaded transmission, the lifting frame 15 and the protective frame 16 move downward, allowing the protective frame 16 to protect the charging area again, thereby preventing the charging contacts from getting contaminated with dust or impurities and ensuring the cleanliness and reliability of the charging contacts.

[0021] like Figures 1-2 As shown, it also includes a sliding frame 3, a return spring 4, and a cleaning brush 5. The sliding frame 3 is slidably connected to the front side of the base plate 2. Return springs 4 are connected between the left and right sides of the sliding frame 3 and the inside of the base plate 2 to provide the sliding frame 3 with a return elastic force. The cleaning brush 5 is connected to the sliding frame 3. The cleaning brush 5 is made of wear-resistant and anti-static bristles. The bristles of the cleaning brush 5 are closely attached to the top surface of the base plate 2, which can effectively contact and clean the base plate 2 and the charging contact surface.

[0022] When the robot returns to charging compartment 1, it moves to the base plate 2 area, where its front end contacts the sliding frame 3 and applies a backward thrust. Under this external force, the sliding frame 3 overcomes the elastic resistance of the return spring 4 and slides backward along the base plate 2, causing the return spring 4 to be in a compressed, energy-storing state. Simultaneously, the sliding frame 3 drives the cleaning brush 5 to move backward in sync. During this movement, the cleaning brush 5 effectively removes dust, impurities, and other foreign matter adhering to the surface through friction between its bristles and the base plate 2 and the charging contact surfaces, ensuring a reliable electrical connection between the robot and the charging contacts. When the robot completes its charging task and exits charging compartment 1, the contact between the robot and the sliding frame 3 gradually disengages. At this time, the compressed return spring 4 releases its elastic potential energy, generating a forward restoring force that pushes the sliding frame 3 forward to reset. During this reset process, the cleaning brush 5 contacts the surface of the base plate 2 again, achieving a secondary cleaning, further ensuring the cleanliness of the charging area, maintaining the good working condition of the charging contacts, and improving the stability and reliability of the charging connection.

[0023] like Figures 1-3 As shown, it also includes a base 6, a dual-axis motor 7, a first screw 8, a sliding block 9, and a connecting frame 10. The dual-axis motor 7 is installed on the lower rear side of the charging compartment 1 by screws. The output shafts at both ends of the motor 7 are connected to the first screw 8 by couplings. The first screw 8 is rotatably connected to the inside of the charging compartment 1. The sliding block 9 is threaded onto the first screw 8 and is slidably connected to the inside of the charging compartment 1. The base 6 is slidably connected to the bottom of the charging compartment 1. The bottom of the base 6 is provided with anti-slip and shock-absorbing pads made of nitrile rubber. The connecting frame 10 is symmetrically connected to the left and right sides of the rear side of the base 6. The connecting frame 10 is slidably connected to the inside of the charging compartment 1, and its inner side is machined into a 45° bevel to contact and cooperate with the sliding block 9. The dual-axis motor 7 is connected to the control system of the charging compartment 1 through electrical circuits.

[0024] After the robot completes the charging contact docking, the control system of the charging chamber 1 sends a command to start the dual-axis motor 7. The output shaft of the motor rotates, which drives the first screw 8 to rotate, thereby moving the sliding block 9 outward. The sliding frame 3 contacts the inclined surface of the connecting frame 10, forcing the connecting frame 10 to lift the charging chamber 1 upward along the base 6. The base 6 always remains in contact with the ground. This process enables the charging chamber 1 to be lifted off the ground, effectively preventing water from entering the ground. After charging is completed, the dual-axis motor 7 reverses, and the first screw 8 drives the sliding block 9 to reset inward. When the sliding block 9 disengages from the connecting frame 10, the charging chamber 1 smoothly falls back to its initial position under the action of gravity.

[0025] like Figure 4As shown, it also includes a rotating frame 11 and a torsion spring 12. The left and right sides of the front side of the base plate 2 are respectively provided with slots, and the rotating frame 11 is rotatably connected to each slot. The rotating frame 11 is distributed in an arc shape and fits the outer surface of the circular robot. The torsion spring 12 is connected between the rotating frame 11 and the inside of the base plate 2. The torsion spring 12 is in a deformed state, and the base 6 abuts against the rotating frame 11.

[0026] When the charging compartment 1 is raised as a whole, the base 6 disengages from the rotating frame 11, releasing the elastic potential energy of the torsion spring 12. The torsion spring 12 drives the rotating frame 11 to rotate rapidly, causing one end of the rotating frame 11 to stand up and form a mechanical limit, thereby constraining the position of the robot on the base plate 2 and preventing it from shifting during charging. When the charging compartment 1 is lowered and reset, the base plate 2 drives the rotating frame 11 to move down synchronously. After the rotating frame 11 contacts the base 6, it is forced to rotate to a horizontal storage state by the reaction force of the base 6, overcoming the elastic force of the torsion spring 12, thus releasing the limit constraint on the robot. At the same time, the torsion spring 12 stores energy again, preparing for the next limit action.
