Description

Technical Field

[0001] The present invention relates to the technical field of battery swap stations, and in particular to a heavy truck battery swap station with the function of cascading battery utilization. Background Art

[0002] New energy electric heavy-duty truck battery swapping stations are energy supply facilities that provide rapid battery replacement services for new energy heavy-duty trucks. By replacing the power battery, they help pure electric heavy-duty trucks to achieve rapid energy replenishment, thereby solving the problems of short driving range and long charging time of electric heavy-duty trucks. Heavy-duty truck battery swapping stations are important infrastructure for the promotion of new energy heavy-duty trucks. Through the advantages of rapid battery replacement, cost reduction, and efficiency improvement, they are gradually changing the traditional heavy-duty truck transportation model and providing strong support for the realization of green logistics. In the heavy truck battery swap system, the steel cable tensioning wheel is driven to move back and forth by the lifting drive component, thereby realizing the transmission of power and the lifting of the battery, and finally the on-board battery is removed from the heavy truck and replaced with a fully charged battery. However, in the process of removing and lifting the battery body, due to the lifting force of the steel cable and the inertia during the movement, the battery body is prone to swing in the air. This swing may not only cause the battery body to collide with the internal structure of the battery swap station, causing damage to the appearance of the battery or even the internal structure, affecting its subsequent use and cascade utilization value, but also make it impossible to effectively clean the outer surface of the battery during the lifting process. Effective cleaning. In addition, the battery swap station has clear inspection requirements for retired batteries, including initial appearance inspection, voltage and internal resistance and other electrical performance parameter inspections, to provide a basis for subsequent cascade utilization. At present, the cleaning operation of the battery body includes external flushing and the removal of mud and sand impurities at the metal port. It must be carried out after the battery is completely disassembled and transported to the designated work station of the battery swap station. This link lags behind the unloading process, which not only prolongs the overall time from unloading to entering the inspection and recycling state, reduces the operating efficiency of the battery swap station, but also significantly increases the labor intensity of manual cleaning, which is not conducive to the continuous and efficient operation of the automated battery swap system.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the lifting block in the disassembly lifting assembly drives the lifting frame and the heavy-duty truck battery body below it to achieve a composite movement of rising, horizontal transfer and lowering. The power of the entire movement comes from the ring chain transmission mechanism, which organically combines lifting and horizontal movement into a set of continuous and stable action processes, significantly enhancing the stability and positioning accuracy of the battery body during disassembly and transportation. During the movement, the system cooperates with multiple special cleaning components to perform all-round treatment on the outer surface of the battery body: the material lifting and cleaning component is responsible for cleaning the main body surface, the interface cleaning component focuses on removing impurities from the metal port, and the swinging scraping component scrapes and cleans the battery all around. In particular, through the cooperation of the interface cleaning component and the interface sweeping component, efficient and thorough cleaning of the battery metal port can be achieved. The system is cleverly designed, integrating the disassembly, transportation and multi-angle cleaning functions of the battery, greatly improving the disassembly efficiency of the heavy-duty truck battery and the processing quality before recycling, providing a good foundation for subsequent detection, sorting and cascade utilization.

[0013] 2. In the present invention, the piston cleaning plate is driven to reciprocate inside the cleaning cylinder by the piston cleaning rod in the lifting and cleaning assembly, generating compressed gas to form positive pressure. The compressed gas is transported to the arc-shaped cleaning seat through the air outlet pipe, and finally ejected through multiple cleaning nozzles evenly arranged on the arc-shaped cleaning seat, forming a directional and concentrated airflow, which effectively blows away the debris, dust and accumulated mud and sand on the top of the heavy-duty truck battery body. The cleaning process is coordinated with the descending movement of the lifting frame. When the lifting frame moves downward, the cleaning system is started synchronously to achieve instant and in-situ cleaning of the battery top.

[0014] 3. In the present invention, the timeliness and automation of the cleaning operation are significantly improved by the material lifting and cleaning assembly, and the interference of pollutants in the subsequent inspection process is avoided. By implementing cleaning intervention during the battery disassembly and lifting stage, the inspection preparation quality of the battery body before subsequent cascade utilization is significantly improved. The top surface of the battery body after cleaning is free of debris, which is convenient for high-precision visual inspection and status assessment of the appearance, which is beneficial to improving the defect recognition rate and the accuracy of the inspection results, while reducing the labor intensity of manual cleaning, and improving the efficiency and reliability of battery processing as a whole.

[0015] 4. In the present invention, the first bevel gear is driven to rotate by the rotating motor in the interface sweeping assembly, and the first bevel gear is meshed with the second bevel gear, thereby transmitting power to the support shaft, driving it to rotate, and the support shaft drives the rotating disk to rotate synchronously with the support shaft. The edge of the rotating disk is hinged with a Z-shaped connecting rod, which can convert the circular motion of the rotating disk into the reciprocating swing of the swing rods on both sides. The end of the swing rod is connected to the L-shaped cleaning brush, driving it to perform high-frequency reciprocating swing in the cleaning hole where the metal port of the battery is located. The L-shaped cleaning brush can effectively remove fine sand, dust and other impurities accumulated on the surface of the metal port, ensuring that the port area is clean and unobstructed. By performing automated and non-contact mechanical cleaning on the metal port before battery testing, the accuracy and reliability of subsequent electrical parameter (such as voltage, internal resistance, etc.) testing are significantly improved, which is conducive to improving the sorting efficiency and evaluation accuracy before battery recycling, while reducing the operational burden and consistency differences caused by manual cleaning.

[0016] 5. In the present invention, the hydraulic telescopic rod in the expansion locking assembly provides power to push the expansion plates at both ends of the lifting frame to move horizontally. The expansion plates are nested outside the U-shaped support plate and maintain stable linear motion under its constraint. During the movement of the expansion plates, the arc-shaped expansion grooves processed on their surfaces cooperate with the arc-shaped expansion rods to convert the horizontal thrust into a specific curved motion. The arc-shaped expansion rods then drive the pushing blocks on the top of the support base to move laterally toward the lifting frame, and then drive the expansion columns connected to the pushing blocks to extend along the guide structure arranged circumferentially on the lifting frame, and finally accurately insert into the lifting ring on the top of the heavy-duty truck battery body, thereby realizing rapid and accurate docking and locking between the lifting frame and the battery lifting ring, significantly improving the stability and positioning accuracy of the battery grabbing process, and providing reliable guarantee for subsequent battery transportation, replacement or testing operations.

[0017] 6. In the present invention, by disassembling the servo motor in the lifting assembly, one of the fixed gears is driven to rotate, and the four fixed gears are meshed with each other to form a synchronous transmission mechanism, which in turn drives the annular closed chain to perform a circular motion along a predetermined trajectory. The annular chain drives the lifting block to move through the connecting rod fixed thereon. When the connecting rod on the chain is in the rising section, the lifting block drives the circular movable plate to perform a vertical rising motion along the fixed column; when the connecting rod moves to the horizontal section, the lifting block moves horizontally in the corresponding guide groove inside the circular movable plate to realize the lateral feeding or adjustment of the movable plate; when the connecting rod enters the descending section, the lifting execution block further drives the circular movable plate to descend synchronously along the fixed column. The transmission mechanism realizes the stable and precise movement of the circular movable plate according to the preset path in three-dimensional space, which is beneficial to improving the positioning accuracy and operation smoothness of the lifting operation.

[0032] See Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8When the lifting block 23 moves horizontally in the circular movable plate 22, the lifting block 23 will carry the heavy-duty truck battery body 11 horizontally into the interior of the battery swap station body 10. At this time, the arc-shaped scraping plate in the swinging scraping assembly swings and cleans the side of the heavy-duty truck battery body 11, and drives the fixed rotating rod 64 to rotate through the fixed gear 24. The fixed rotating rod 64 drives the third bevel gear 65 to rotate, and the third bevel gear 65 engages with the fourth bevel gear 66 to drive the rotating rod 67 to rotate synchronously. The rotating rod 67 drives the rotating cylinder 63 at the bottom to rotate stably.

The expansion locking assembly includes an expansion plate 90 and a hydraulic telescopic rod 78. The expansion locking assembly also includes a support base 73 and a push block 74. The support base 73 is fixedly installed at the bottom of both ends of the lifting frame 70. The support base 73 is provided with a support slide 75. Both ends of the support slide 75 are slidably connected to a support slider 76. The push block 74 is fixedly mounted on the support At the top of the slider 76, the expansion column 77 is fixedly mounted on the pushing block 74, and the expansion column 77 is movable around the outside of the lifting frame 70. A hydraulic telescopic rod 78 is fixedly mounted at the center of the inner part of the lifting frame 70. The output ends of the hydraulic telescopic rod 78 are fixedly mounted with expansion plates 90, and the expansion plates 90 are movable through the U-shaped support plate 91. The expansion plate 90 is provided with an arc-shaped expansion groove 92, and an arc-shaped expansion rod 93 is provided in the arc-shaped expansion groove 92, and the bottom end of the arc-shaped expansion rod 93 is fixedly mounted at the top of the pushing block 74.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 10 and Figure 11 The expansion plates 90 at both ends of the lifting frame 70 are pushed to move by the hydraulic telescopic rod 78, and the expansion plates 90 achieve stable horizontal movement in the U-shaped support plate 91. During the movement, the expansion plates 90 drive the arc expansion rods 93 to move through the arc expansion grooves 92. The arc expansion grooves 92 drive the pushing blocks 74 on the top of the support base 73 to move toward the side of the lifting frame 70 through the arc expansion rods 93. The pushing blocks 74 will carry the expansion columns 77 through the four sides of the lifting frame 70 and enter the lifting rings at the top of the heavy-duty truck battery body 11, accurately and stably clamping the lifting frame 70 into the lifting rings of the heavy-duty truck battery body 11.

[0035] Working principle: Drive the heavy-duty truck to the bottom of the battery swap station body 10, align the lifting frame 70 with the center of the top lifting ring of the heavy-duty truck battery body 11, and push the expansion plates 90 at both ends of the lifting frame 70 to move through the hydraulic telescopic rod 78. The expansion plates 90 achieve stable horizontal movement in the U-shaped support plate 91. During the movement, the expansion plates 90 drive the arc expansion rod 93 to move through the arc expansion groove 92. The arc expansion groove 92 drives the pushing block 74 on the top of the support base 73 to move toward the side of the lifting frame 70 through the arc expansion rod 93. The pushing block 74 will carry the expansion column 77 through the four sides of the lifting frame 70 and enter the lifting ring at the top of the heavy-duty truck battery body 11, so that the lifting frame 70 is accurately and stably stuck in the lifting ring of the heavy-duty truck battery body 11. There will be no shaking during the disassembly and lifting of the heavy-duty truck battery body 11, which greatly improves the safety and stability of the heavy-duty truck battery body 11 during the disassembly process. After the lifting frame 70 firmly supports the heavy truck battery body 11, the servo motor 28 drives one of the fixed gears 24 to rotate, and the four fixed gears 24 cooperate with each other to drive the ring chain 21 to rotate. The ring chain 21 drives the lifting block 23 to move through the connecting rod 29. When the connecting rod 29 on the ring chain 21 is in an upward movement, the lifting block 23 drives the circular movable plate 22 to achieve synchronous upward movement in the fixed column 25. When the connecting rod 29 of the ring chain 21 is in a horizontal movement, the lifting block 23 will move horizontally in the circular movable plate 22. When the connecting rod 29 of the ring chain 21 is in a downward movement, the lifting block 23 drives the circular movable plate 22 to achieve synchronous downward movement in the fixed column 25. When the lifting block 23 and the circular movable plate 22 move downward synchronously, the lifting block 23 lowers the lifting frame 70 to the lifting ring of the heavy-duty truck battery body 11 through the lifting plate 71. During the lowering process, the circular movable plate 22 lowers the piston cleaning rod 32 through the first connecting plate 31. The piston cleaning rod 32 will bring the piston cleaning plate 34 to generate positive pressure inside the cleaning cylinder 30. The compressed air inside the cleaning cylinder 30 enters the arc-shaped cleaning seat 33 through the air outlet pipe 37, and then blows and cleans the debris on the top of the heavy-duty truck battery body 11 through the cleaning nozzle 35 on the arc-shaped cleaning seat 33. The descending lifting frame 70 cleans the top of the heavy-duty truck battery body 11 in time, which is convenient for the subsequent cascade utilization detection of the heavy-duty truck battery body 11 and the clear detection of the top appearance of the heavy-duty truck battery body 11, thereby improving the accuracy of the appearance detection. When the lifting block 23 moves horizontally in the circular movable plate 22, the lifting block 23 will carry the heavy-duty truck battery body 11 horizontally into the interior of the battery swap station body 10. At this time, the arc-shaped scraping plate in the swinging scraping assembly swings and cleans the side of the heavy-duty truck battery body 11, and drives the fixed rotating rod 64 to rotate through the fixed gear 24. The fixed rotating rod 64 drives the third bevel gear 65 to rotate, and the third bevel gear 65 engages with the fourth bevel gear 66 to drive the rotating rod 67 to rotate synchronously. The rotating rod 67 drives the bottom rotating cylinder 63 to rotate stably. During the rotation process, the rotating cylinder 63 drives the rack plate 61 on the arc motion rod 83 to move up and down in the arc limit plate 80 through the S-shaped rotating groove 68. During the reciprocating lifting process, the rack plate 61 engages with the rotating rod during the lifting process. The driving gear 62 on the shaft 69 rotates, and the driving gear 62 will carry the arc-shaped scraping brush 60 to perform side cleaning movement on the heavy-duty truck battery body 11. In addition, when the heavy-duty truck battery body 11 descends in the battery swap station body 10, the arc-shaped scraping brush 60 is also scraping the descending heavy-duty truck battery body 11. During the whole process, the arc-shaped scraping brush 60 is used to scrape and clean the heavy-duty truck battery body 11 that moves horizontally and vertically. The scraping and cleaning of multiple groups of motion combinations greatly improves the cleaning effect, expands the contact area and contact time between the heavy-duty truck battery body 11 and the arc-shaped scraping brush 60, and greatly improves the scraping effect on the heavy-duty truck battery body 11, so that the heavy-duty truck battery body 11 after entering the battery swap station body 10 is thoroughly and comprehensively scraped and cleaned, which is convenient for the subsequent cascade utilization detection effect of the heavy-duty truck battery body 11.

[0036] When the lifting block 23 and the circular movable plate 22 move upward synchronously, the cleaning cylinder 30 is filled with air through the air inlet pipe 36, and the heavy-duty truck battery body 11 after entering the battery swap station body 10 moves downward again along the ring chain 21. Similarly, the cleaning rod cooperates with the cleaning nozzle 35 to clean the top of the heavy-duty truck battery body 11 again. After the heavy-duty truck battery body 11 enters the specified position of the battery swap station body 10, the metal port of the heavy-duty truck battery body 11 enters the cleaning hole 12. After insertion, the lifting frame 70 contacts the limit support of the hanging ring on the top of the heavy-duty truck battery body 11, cleans the metal port through the interface sweeping assembly, and drives the first bevel gear on the rotating shaft 53 through the rotating motor 50. The wheel 54 rotates, the first bevel gear 54 engages with the second bevel gear 56 to drive the support shaft 55 to rotate, the support shaft 55 drives the rotating disk 51 to rotate synchronously, the rotating disk 51 drives the Z-type connecting rod 52 to rotate, and the rotation of the Z-type connecting rod 52 drives the swing rods 57 on both sides to swing synchronously, and the swing rods 57 will drive the L-shaped cleaning brush 15 to swing back and forth in the cleaning hole 12, and the L-shaped cleaning brush 15 swings back and forth to clean the metal port, and discharges the fine sand and impurities on the metal port, so as to facilitate the subsequent operation and inspection of the metal port of the heavy-duty truck battery body 11, and facilitate accurate detection of the voltage, resistance, etc. inside the heavy-duty truck battery body 11.

[0037] The lifting frame 70 resets along with the circular chain 21. At this time, the lifting block 23 and the circular movable plate 22 rise synchronously, and the second connecting plate 41 cooperates with the piston cleaning rod 42 and the piston cleaning plate to generate positive pressure inside the cleaning cylinder 40. The compressed air in the cleaning cylinder 40 enters the blast cleaning seat 43 through the exhaust pipe 46, and then the inside of the metal port is cleaned through the cleaning nozzle on the blast cleaning seat 43. The metal port after brushing is cleaned by blasting. When the lifting block 23 moves down again along with the circular movable plate 22, the inside of the cleaning cylinder 40 is filled with gas through the inflation pipe 45, waiting for the next step of cleaning the metal port.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
