Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a guide buffer structure for reducing frictional loss of charging electrode plates. Background Technology

[0002] With the widespread application of lifting robots in warehousing and logistics, the demand for automatic charging is becoming increasingly prominent. Currently, charging piles and robots mainly achieve power transmission through metal electrode contact. However, in actual operation, due to limitations in robot positioning accuracy and factors such as vibration, rigid contact between metal electrodes can easily cause a series of technical problems.

[0003] Specifically, existing charging piles have direct, rigid contact between the metal electrodes and the lifting robot's end electrodes, leading to several problems during robot docking and charging: First, longitudinal friction occurs, with robot positioning errors causing scratches between the metal electrodes, accelerating surface oxidation and wear. Second, poor contact occurs, with oxide layer buildup increasing contact resistance, potentially causing charging failure, overheating, or even fire. Simultaneously, dust particles from the work area adhere to the surface of the charging metal electrodes, exacerbating friction and wear, and forming an insulating layer, severely impacting charging efficiency and safety. Traditional solutions primarily mitigate wear by adding precious metal coatings or using spring-floating structures, but these methods are costly and cannot completely eliminate friction, while also ignoring the impact of dust contamination on the charging system.

[0031] like Figures 1-8 The diagram shows a guide buffer structure for reducing frictional losses of charging electrodes.

[0032] Example 1

[0033] The device includes a stabilizing block 1, with upper and lower reset springs 2 connected to the lower middle part of the stabilizing block 1. A mounting block 3 is connected to the lower end of the upper and lower reset springs 2, and a housing 4 is connected to the lower end of the mounting block 3. Front and rear reset springs 5 ​​are connected to the upper and lower parts of one side of the inner wall of the housing 4. One end of each of the two front and rear reset springs 5 ​​is connected to a charging pile terminal plate 6. Guide rods 7 are connected to one side of each charging pile terminal plate 6, corresponding to the side of each front and rear reset spring 5.

The cleaning component ensures the cleaning and maintenance of the charging pile end plate 6, ensuring that it always maintains good conductivity.

[0036] The cleaning component includes two sets of rails 11. Each set of two rails 11 has a sliding block 12 slidably connected to its upper end.

[0037] In this embodiment, the support rail 11 is an electrically controlled slide rail, and the upper ends of the two moving blocks 12 are connected to the moving frame 13. The moving frame 13 is located on the outer wall of the charging pile end plate 6 and is shaped like an inverted U to improve the stability of the moving frame 13.

The moving trajectory and speed of the cleaning frame 19 can be precisely controlled according to the cleaning requirements to ensure that dust, impurities and other debris on the surface of the charging pile end plate 6 can be effectively removed and maintain the good working performance of the charging pile.

[0038] Example 3

[0039] Two connecting blocks are connected to a cleaning frame 19 at one end. A cleaning port is opened on the upper part of one side of the cleaning frame 19. Scrapers 20 are connected to both sides of the inner wall of the cleaning frame 19. One end of the scraper 20 extends through to one side of the cleaning frame 19, and the other end of the scraper 20 is located inside the cleaning port. A wiping roller 21 is connected to the lower end of the inner wall of the cleaning frame 19, corresponding to the area below the scraper 20. A cleaning motor is connected to one end of the wiping roller 21 on one side of the inner wall of the cleaning frame 19. One end of the cleaning motor is connected to one end of the wiping roller 21, and the other end of the wiping roller 21 is located inside the cleaning port. A collection box 22 is connected to the lower end of the inner wall of the cleaning frame 19. One end of the collection box 22 extends through to one side of the cleaning frame 19. A pull plate is connected to one side of the collection box 22, and one side of the pull plate contacts one side of the cleaning frame 19. A negative pressure air pump 23 is connected to one side of the lower end of the inner wall. A filter screen 24 is connected to one side of the lower end of the inner wall of the collection box 22. The upper end of the filter screen 24 is connected to the upper end of the inner wall of the collection box 22. The filter screen 24 is located on one side of the negative pressure air pump 23. One side of the collection box 22 is in contact with one side of the inner wall of the cleaning frame 19. A first ash collection pipe 25 is connected to the middle of one side of the collection box 22. One end of the first ash collection pipe 25 extends through to one side of the cleaning frame 19. Both the upper and lower ends of the first ash collection pipe 25 are inclined. A second ash collection pipe 26 is connected to one side of the upper end of the collection box 22. The upper end of the second ash collection pipe 26 is in contact with one side of the lower end of the wiping roller 21. The upper end of the second ash collection pipe 26 is arc-shaped. The shape of the upper end of the second ash collection pipe 26 matches the shape of the lower end of the wiping roller 21.

[0040] In this embodiment, the cleaning opening on the upper part of one side of the cleaning frame 19 is specially designed in size and shape to ensure that the scraper 20 and the wiping roller 21 can contact the charging pile end plate 6. The scraper 20 is made of wear-resistant rubber, which can closely adhere to the surface of the end plate, and one end extends to the cleaning opening to effectively scrape off dust, oxides and other impurities. The surface of the wiping roller 21 is covered with a highly absorbent microfiber cloth, and the cleaning motor drives it to rotate at high speed. After the initial cleaning by the scraper 20, it further removes fine particles, improves the smoothness and conductivity of the charging pile end plate 6, and collects... The collection box 22 is used to collect cleaning waste. One end extends to the outside of the cleaning frame 19. The pull plate facilitates manual cleaning. The negative pressure air pump 23, together with the filter screen 24, forms a negative pressure dust suction structure to prevent dust leakage. The first dust collection pipe 25 is designed with an inclination to guide the material using gravity and negative pressure. The second dust collection pipe 26 is attached to the lower end of the wiping roller 21 to collect residual dust in time and avoid secondary pollution. Through the coordinated operation of components such as the cleaning frame 19, scraper 20, and wiping roller 21, a high-efficiency cleaning and collection system is formed to ensure the cleaning performance of the charging pile terminal plate 6 and extend the service life of the equipment.

[0041] Working Principle: In the automatic charging process of the liftable robot, as the robot approaches the charging station, charging preparation work begins in an orderly manner. The robot's endplate, as a key component for power transmission, first contacts the guide seat 8. The guide seat 8's special inclined chamfered structure provides a clear guiding direction for the docking of the robot's endplate and the charging station's endplate 6. As the robot continues to approach, the robot's endplate moves towards the guide seat 8. During this process, the guide seat 8 experiences continuously increasing pressure. This pressure is transmitted through the guide seat 8, causing the connected charging station endplate 6, guide rod 7, housing 4, and two sliders 9 to move downwards together. During this downward movement, the upper... The lower reset spring 2 is stretched, and thanks to its own elastic properties, it generates elastic potential energy when stretched, storing energy for the subsequent reset process. During the movement, the two sliders 9 slide inside the two connecting slide rails 10 respectively. The sliding structure formed by the connecting slide rails 10 and the sliders 9 ensures the stability and accuracy of the entire movement process, effectively reducing docking errors that may be caused by shaking or offset. With the coordinated cooperation of all components, the robot end plate and the charging pile end plate 6 achieve frictionless contact. At this time, the front and rear reset springs 5 ​​play a key role, providing just the right contact pressure between the two plates, ensuring stable and reliable electrical connection, and laying a solid foundation for the subsequent charging process.

[0042] When the robot detaches from the charging station: When the robot completes its charging task and needs to detach from the charging station, the robot's end plate gradually moves away from the charging station's end plate 6. During this movement, the robot's end plate remains in contact with the guide seat 8, which continues to play a crucial guiding role. As the robot continues to move away from the charging station, the robot's end plate moves along the inclined section of one end of the guide seat 8. At this time, the upper and lower reset springs 2, which were stretched during the docking process, begin to release energy based on their stored elastic potential energy. Under the action of elastic tension, the charging station's end plate 6 and the housing 4 slowly reset. During the reset process, the two sliders 9 continue to slide inside the two connecting slide rails 10. The limiting and guiding functions of the connecting slide rails 10 on the sliders 9 ensure the stable movement of the charging station's end plate 6 during the reset process, allowing it to accurately return to its initial height, ready for the next automatic docking task, thus ensuring the normal operation and subsequent use of the charging equipment.

[0043] During the cleaning of the charging pile terminal plates: After the robot moves away from the charging pile, in order to ensure the good performance and service life of the charging pile terminal plates 6, it is necessary to clean the dust on their surface. The rail 11, as an electrically controlled slide rail, starts working after receiving the cleaning command. Two moving blocks 12 move above the rail 11, accurately transporting the moving frame 13 to one side of the charging pile terminal plate 6. The moving frame 13 has an inverted U-shaped structure. When the moving frame 13 is in parallel with one side of the charging pile terminal plate 6, the cleaning frame 19 installed on the moving frame 13 is also correspondingly positioned on one side of the charging pile terminal plate 6, and the cleaning work begins. When the drive motor 14 starts, the rotational power at its output end is transmitted through the transmission wheel 16 and the transmission belt 17, driving the two lead screws 15 to rotate synchronously. When the lead screws 15 rotate, their helical structure converts the rotational motion into linear motion, causing the guide block 18 sleeved on the lead screw 15 to move along the axial direction of the lead screw 15. The movement of the guide block 18 pushes the connecting block to slide in the connecting groove of the moving frame 13, thereby causing the cleaning frame 19 to reciprocate along one side of the charging pile end electrode 6. The scraper 20 on the inner wall of the cleaning frame 19 is made of a special wear-resistant material and, driven by the cleaning frame 19, closely adheres to the charging pile end electrode 6. The charging pile terminal plate 6 can effectively scrape off dust, oxides, or metal debris adhering to its surface. Subsequently, the wiping roller 21, driven by a cleaning motor, begins to rotate. The surface of the wiping roller 21 is made of a soft and absorbent material. During the rotation, it further wipes the surface of the charging pile terminal plate 6, not only removing the fine impurities that the scraper 20 failed to remove, but also improving the conductivity of the plate surface through physical friction. During the cleaning process, the negative pressure air pump 23 creates a negative pressure environment in the collection box 22 by drawing air. Under the action of negative pressure, the scraped debris passes through the first dust collection pipe 25. Inside the collection box 22, the filter 24 plays an interception role. Its fine mesh structure can intercept debris and cause it to settle at the bottom of the box. At the same time, the second dust collection pipe 26 can collect the dust generated on the surface of the wiping roller 21 during the wiping process, effectively preventing excessive dust residue on the surface of the wiping roller 21 and avoiding secondary pollution during subsequent cleaning. When the dust accumulation in the collection box 22 reaches a certain amount, the pull plate can be pulled periodically to easily clean the dust accumulation in the collection box 22. Multiple cleanings from top to bottom ensure the cleaning effect of the charging pile terminal plate 6.

[0044] The above specific embodiments are only one optional embodiment of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
