Description

Technical Field

[0001] This invention relates to the field of battery swapping station technology, and in particular to a heavy-duty truck battery swapping station with the function of cascade utilization of batteries. Background Technology

[0002] Battery swapping stations for new energy electric heavy-duty trucks are energy replenishment facilities specifically designed to provide rapid battery replacement services for these trucks. By swapping the power batteries, they help pure electric heavy-duty trucks quickly replenish their energy, thus solving problems such as short driving range and long charging times. Battery swapping stations are a crucial infrastructure for the promotion of new energy heavy-duty trucks. Through advantages such as rapid battery swapping, reduced costs, and improved efficiency, they are gradually changing the traditional heavy-duty truck transportation model and providing strong support for the realization of green logistics.

[0003] In heavy-duty truck battery swapping systems, a lifting drive assembly drives a steel cable tensioning wheel in a reciprocating motion, thereby transmitting power and lifting the battery. Ultimately, the onboard battery is removed from the heavy-duty truck and replaced with a fully charged battery. However, during the disassembly and lifting of the battery, due to the lifting force of the steel cable and the inertia of the movement, the battery is prone to swaying in mid-air. This swaying can not only cause the battery to collide with the internal structure of the swapping station, resulting in external damage or even internal structural damage, affecting its subsequent use and reuse value, but also makes it impossible to effectively clean the outer surface of the battery during the lifting process. In addition to efficient cleaning, battery swapping stations have clear testing requirements for retired batteries, including initial visual inspection and testing of electrical performance parameters such as voltage and internal resistance, to provide a basis for subsequent cascade utilization. Currently, the cleaning of battery bodies, including external rinsing and removal of mud and sand impurities at metal ports, can only be carried out after the batteries have been completely disassembled and transported to the designated work station of the battery swapping station. This step lags behind the unloading process, which not only prolongs the overall time from battery unloading to entering the testing and recycling state, reducing the operational efficiency of the battery swapping 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 swapping system. Summary of the Invention

The bottom end of the arc-shaped expansion rod is fixedly installed at the top of the push block.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. In this invention, the lifting block in the lifting assembly is disassembled to drive the lifting frame and the heavy truck battery body below it, realizing a compound motion of rising, horizontal transfer and falling. The power of the entire motion comes from the ring chain transmission mechanism, which organically combines lifting and horizontal motion into a continuous and stable action process, significantly enhancing the stability and positioning accuracy of the battery body during disassembly and transfer. During the motion, the system coordinates multiple dedicated cleaning components to perform all-round treatment on the outer surface of the battery body: the lifting and cleaning component is responsible for cleaning the main surface, the interface cleaning component focuses on removing impurities from the metal ports, and the swinging dust scraping component scrapes and cleans the area around the battery. In particular, the cooperation between the interface cleaning component and the interface sweeping component can achieve efficient and thorough cleaning of the battery's metal ports. The system is ingeniously designed to integrate battery disassembly, transportation and multi-angle cleaning functions, greatly improving the disassembly efficiency of heavy truck batteries and the processing quality before recycling, providing a good foundation for subsequent testing, sorting and tiered utilization.

[0016] 2. In this invention, the piston cleaning rod in the material lifting and cleaning assembly drives the piston cleaning plate to reciprocate inside the cleaning cylinder, generating compressed gas to form positive pressure. This compressed gas is transported to the arc-shaped cleaning seat through the air outlet pipe, and finally sprayed out through multiple cleaning nozzles evenly arranged on the arc-shaped cleaning seat, forming a directional and concentrated airflow to effectively blow away and clean the debris, dust and accumulated mud and sand on the top of the heavy truck battery. This cleaning process is carried out in coordination with the downward movement of the lifting frame. When the lifting frame moves downward, the cleaning system starts synchronously to achieve immediate and in-situ cleaning of the top of the battery.

[0017] 3. In this invention, the material lifting and cleaning component significantly improves the timeliness and automation of the cleaning operation, avoids contaminants interfering with subsequent testing processes, and significantly improves the quality of testing preparation before the battery body is used in subsequent tiered applications by implementing cleaning intervention during the battery disassembly and lifting stage. The cleaned battery body has no debris obstructing its top surface, which facilitates high-precision visual inspection and status assessment, which helps to improve the defect identification rate and the accuracy of the test results. At the same time, it reduces the labor intensity of manual cleaning and improves the overall efficiency and reliability of battery processing.

[0018] 4. In this invention, the first bevel gear is driven to rotate by the rotary motor in the interface sweeping assembly. The first bevel gear meshes with the second bevel gear, thereby transmitting power to the support shaft and causing it to rotate. The support shaft drives the rotating disk to rotate synchronously with the support shaft. A Z-shaped connecting rod is hinged to the edge of the rotating disk, 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 an L-shaped cleaning brush, which drives it to perform high-frequency reciprocating swing in the cleaning hole where the battery metal port 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 of the metal port before battery testing, the accuracy and reliability of subsequent electrical parameter (such as voltage, internal resistance, etc.) testing are significantly improved. This is beneficial to improving the sorting efficiency and evaluation accuracy before battery cascade utilization, while reducing the operational burden and consistency differences caused by manual cleaning.

[0019] 5. In this 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 push block at the top of the support base to move laterally toward the lifting frame, thereby driving the expansion column connected to the push block to extend along the guide structure arranged circumferentially on the lifting frame, and finally accurately inserting it into the lifting ring at the top of the heavy truck battery body. This achieves 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 gripping process, and providing reliable protection for subsequent battery transfer, replacement, or inspection operations.

[0020] 6. In this invention, the servo motor in the lifting assembly drives one of the fixed gears to rotate. The four fixed gears mesh with each other to form a synchronous transmission mechanism, which in turn drives the annular closed chain to circulate along a predetermined trajectory. The annular chain drives the lifting block to move through the connecting rod fixed on it. When the connecting rod on the chain is in the rising section, the lifting block drives the U-shaped movable plate to move vertically upward 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 U-shaped movable plate to realize the lateral feeding or adjustment of the movable plate. When the connecting rod enters the falling section, the lifting execution block further drives the U-shaped movable plate to fall synchronously along the fixed column. The transmission mechanism realizes the stable and precise movement of the U-shaped movable plate in three-dimensional space along a preset path, which is beneficial to improving the positioning accuracy and running stability of the lifting operation.

[0034] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0035] Example: Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, a heavy-duty truck battery swapping station with a function of cascaded battery utilization includes a swapping station body 10 and a heavy-duty truck battery body 11. A disassembly and lifting assembly is installed at the top of the swapping station body 10. This assembly is used to disassemble and transport the heavy-duty truck battery body 11 from the heavy-duty truck into the swapping station body 10. The disassembly and lifting assembly includes a ring chain 21, a U-shaped movable plate 22, and a lifting block 23. During the movement of the ring chain 21 and the lifting block 23, the U-shaped movable plate 22 undergoes a lifting and lowering motion. The disassembly and lifting assembly also includes a fixing frame 20 fixedly installed at the top of the swapping station body 10. The fixing frame 20 has a perimeter around one side... A rotating shaft is connected to fixed gears 24, and an annular chain 21 is movably connected to the outer periphery of the four fixed gears 24. The annular chain 21 cooperates with the fixed gears 24 to achieve square motion. Fixed columns 25 are fixedly installed at both ends inside the fixed frame 20. The two ends of the U-shaped movable plate 22 are movably passed through the fixed columns 25. The U-shaped movable plate 22 undergoes stable lifting and lowering motion in the fixed columns 25. A T-shaped slide groove 26 is opened inside the U-shaped movable plate 22. A T-shaped slider 27 is slidably connected in the T-shaped slide groove 26, and a lifting block 23 is fixedly installed between the T-shaped slider 27. The lifting block 23 moves back and forth stably in the T-shaped slider 27 and the T-shaped slide groove 26.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A servo motor 28 is fixedly installed at the top of the fixed frame 20 at the end away from the arc-shaped scraper brush 60, and the output end of the servo motor 28 is fixedly installed on the rotating shaft of the fixed gear 24. A lifting frame 70 is fixedly installed at the bottom of the lifting block 23 through the lifting plate 71. The lifting plate 71 is movably inserted through the lifting groove 72 opened at the bottom of the fixed frame 20, and the lifting frame 70 is movably located on the outer side of the bottom of the fixed frame 20. A connecting rod 29 is fixedly installed on the annular chain 21. The connecting rod 29 is movably connected to the lifting block 23 and is fixedly installed on the link of the annular chain 21. The annular chain 21 drives the lifting block 23 to move through the connecting rod 29. The U-shaped movable plate 22 is movably located at the top of the two fixed gears 24 at the bottom of the fixed frame 20.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7After the lifting frame 70 provides stable support for the heavy truck battery body 11, the servo motor 28 drives one of the fixed gears 24 to rotate. The four fixed gears 24 cooperate 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 moves upward, the lifting block 23 drives the U-shaped movable plate 22 to move upward synchronously in the fixed column 25. When the connecting rod 29 of the ring chain 21 moves horizontally, the lifting block 23 will move horizontally in the U-shaped movable plate 22. When the connecting rod 29 of the ring chain 21 moves downward, the lifting block 23 drives the U-shaped movable plate 22 to move downward synchronously in the fixed column 25.

[0038] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A material lifting and cleaning assembly is provided at one end of the U-shaped movable plate 22. When the lifting block 23 drives the bottom lifting frame 70 to descend and move to the top of the heavy truck battery body 11, the cleaning cylinder 30 in the material lifting and cleaning assembly works with the lifting frame 70 to clean debris from the top of the heavy truck battery body 11. The material lifting and cleaning assembly also includes a first connecting plate 31, a piston cleaning rod 32, and an arc-shaped cleaning seat 33.

An air inlet pipe 36 and an air outlet pipe 37 are fixedly installed at the bottom of the cleaning cylinder 30, and the air outlet pipe 37 is connected to the arc-shaped cleaning seat 33. One-way valves are installed on both the air inlet pipe 36 and the air outlet pipe 37. The one-way valve on the air inlet pipe 36 allows the cleaning cylinder 30 to be filled with gas in one direction only, and the one-way valve on the air outlet pipe 37 allows the compressed air inside the cleaning cylinder 30 to be discharged in one direction only.

[0039] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6When the lifting block 23 and the U-shaped movable plate 22 move down synchronously, the lifting block 23, through the lifting plate 71, carries the lifting frame 70 down to the lifting ring of the heavy truck battery body 11. During the descent, the U-shaped movable plate 22, through the first connecting plate 31, carries the piston cleaning rod 32 down. The piston cleaning rod 32, along with the piston cleaning plate 34, generates 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 37, and then blows and cleans the debris on the top of the heavy 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 truck battery body 11 in a timely manner, which facilitates the subsequent tiered utilization inspection of the heavy truck battery body 11, and allows for a clear inspection of the top appearance of the heavy truck battery body 11, improving the accuracy of appearance inspection.

[0040] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 An interface cleaning component is provided at the other end of the U-shaped movable plate 22.

An air inlet pipe 45 and an exhaust pipe 46 are fixedly installed on the top of the cleaning cylinder 40, and the exhaust pipe 46 is connected to the blower cleaning seat 43. Both the air inlet pipe 45 and the exhaust pipe 46 are equipped with one-way valves. The air inlet pipe 45, in conjunction with the one-way valve, fills the inside of the cleaning cylinder 40 with air, and the exhaust pipe 46, in conjunction with the one-way valve, discharges the compressed air inside the cleaning cylinder 40 in one direction. The blower cleaning seat 43 is evenly equipped with several cleaning nozzles with the outlet facing upward. The cleaning nozzles are installed on the side of the cleaning hole 12. The fixing bracket 20 has fixing grooves 47 at both ends, and the first connecting plate 31 and the second connecting plate 41 are movably inserted through the fixing grooves 47.

[0041] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8The lifting frame 70 moves to its reset position along with the ring chain 21. At this time, the lifting block 23 and the loop-shaped movable plate 22 move upward synchronously. Through the second connecting plate 41, the piston cleaning rod 42 and the piston cleaning plate generate positive pressure inside the cleaning cylinder 40. The compressed air inside the cleaning cylinder 40 enters the blower cleaning seat 43 through the exhaust pipe 46, and then cleans the inside of the metal port through the cleaning nozzle on the blower cleaning seat 43. The metal port is cleaned by blowing air after brushing. When the lifting block 23 moves downward again with the loop-shaped movable plate 22, gas is filled into the cleaning cylinder 40 through the air filling pipe 45.

The L-shaped cleaning brush 15 moves in the cleaning hole 12 and is in contact with the metal port at the bottom of the heavy truck battery body 11.

[0043] See Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10When the lifting block 23 and the loop-shaped movable plate 22 move upward synchronously, the cleaning cylinder 30 is filled with air through the air inlet pipe 36. After entering the battery swapping station body 10, the heavy truck battery body 11 moves downward again with the ring chain 21. Similarly, the cleaning rod and the cleaning nozzle 35 clean the top of the heavy truck battery body 11 again. After the heavy truck battery body 11 enters the designated position in the battery swapping station body 10, the metal port of the heavy truck battery body 11 enters the cleaning hole 12. After insertion, the lifting frame 70 contacts and limits the lifting ring on the top of the heavy truck battery body 11. The metal port is cleaned by the interface sweeping component. The first cone on the rotating shaft 53 is driven by the rotating motor 50. The gear 54 rotates, and the first bevel gear 54 meshes 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-shaped connecting rod 52 to rotate. During the rotation of the Z-shaped connecting rod 52, it drives the swing rods 57 on both sides to swing synchronously. The swing rods 57 drive the L-shaped cleaning brush 15 to swing back and forth in the cleaning hole 12. The L-shaped cleaning brush 15 swings back and forth to clean the metal port, and removes fine sand and impurities from the metal port, which facilitates the subsequent operation and testing of the metal port of the heavy truck battery body 11, and facilitates the accurate testing of the voltage, resistance and other parameters inside the heavy truck battery body 11.

[0044] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The battery swapping station body 10 is equipped with swing-type dust scraping components on both sides inside. The arc-shaped dust scraping brush 60 in the swing-type dust scraping components is used to clean the dust on the outside of the heavy truck battery body 11. The swing-type dust scraping components also include a rack plate 61, a drive gear 62 and a rotating cylinder 63. The fixed frame 20 is movably connected to a fixed rotating rod 64 at the bottom of the end away from the servo motor 28, and the fixed rotating rod 64 is connected to the rotating shaft of the fixed gear 24. A third bevel gear 65 is fixedly installed on the fixed rotating rod 64. A fourth bevel gear 66 is meshed at the bottom of the third bevel gear 65. A rotating rod 67 is fixedly installed at the bottom center of the fourth bevel gear 66. A rotating cylinder 63 is fixedly installed at the bottom end of the rotating rod 67. An arc-shaped limiting plate 80 is fixedly installed inside the battery swapping station body 10. The arc-shaped limiting plate 80 has a limiting groove 81. A limiting slider 82 is slidably connected in the limiting groove 81. The rack plate 61 is fixedly installed on the limiting slider 82. The drive gear 62 moves symmetrically on both sides of the rack plate 61.

[0045] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The battery swapping station body 10 has drive gears 62 movably connected to both sides of the arc-shaped limiting plate 80 via connecting shafts 69, and the drive gears 62 are movably meshed with the rack plate 61. The outer periphery of the rotating cylinder 63 is provided with an S-shaped rotating groove 68, and an arc-shaped moving rod 83 is movably arranged in the S-shaped rotating groove 68. The arc-shaped moving rod 83 is fixedly installed on the rack plate 61. The arc-shaped dust scraper 60 is fixedly installed on the drive gear 62. The arc-shaped dust scraper 60 scrapes and cleans the side of the heavy truck battery body 11. The arc-shaped dust scraper 60 moves symmetrically on both sides inside the battery swapping station body 10.

[0046] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 When the lifting block 23 moves horizontally in the U-shaped movable plate 22, the lifting block 23 will carry the heavy truck battery body 11 horizontally into the interior of the battery swapping station body 10. At this time, the arc-shaped scraper in the swing scraper assembly swings and cleans the side of the heavy truck battery body 11. The fixed gear 24 drives the fixed rotating rod 64 to rotate. The fixed rotating rod 64 drives the third bevel gear 65 to rotate. The third bevel gear 65 meshes with the fourth bevel gear 66 to drive the rotating rod 67 to rotate synchronously. The rotating rod 67 carries the bottom rotating cylinder 63 to rotate stably. During the rotation, the rotating cylinder 63 carries the rack plate 61 on the arc-shaped moving rod 83 to move up and down in the arc-shaped limiting plate 80 through the S-shaped rotating groove 68. During the reciprocating up and down movement, the rack plate 61 meshes and connects during the up and down movement. The drive gear 62 on the rotating shaft 69 rotates, and the drive gear 62 carries the arc-shaped scraper brush 60 to perform side cleaning on the heavy truck battery body 11. In addition, when the heavy truck battery body 11 descends in the battery swapping station body 10, the arc-shaped scraper brush 60 also scrapes the heavy truck battery body 11 as it descends. Throughout the process, the arc-shaped scraper brush 60 scrapes and cleans the heavy truck battery body 11 in both horizontal and vertical movements. The combination of multiple motions greatly improves the cleaning effect, expands the contact area and contact time between the heavy truck battery body 11 and the arc-shaped scraper brush 60, and greatly improves the scraping effect on the heavy truck battery body 11. This ensures that the heavy truck battery body 11 is thoroughly and completely cleaned after entering the battery swapping station body 10, which facilitates the subsequent testing of the heavy truck battery body 11 for reuse.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11The lifting frame 70 is internally equipped with an expansion locking assembly. An expansion post 77 within the expansion locking assembly supports and limits the lifting ring at the top of the heavy truck battery body 11. The expansion locking assembly includes an expansion plate 90 and a hydraulic telescopic rod 78. It also includes a support base 73 and a push block 74. Support bases 73 are fixedly installed at the bottom of both ends of the lifting frame 70. Each support base 73 has a support groove 75, with support sliders 76 slidably connected to both ends of the support groove 75. The push block 74 is fixedly installed on the support... At the top of the slider 76, an expansion column 77 is fixedly installed on the push block 74, and the expansion column 77 moves through the outer perimeter of the lifting frame 70. A hydraulic telescopic rod 78 is fixedly installed at the center of the lifting frame 70. An expansion plate 90 is fixedly installed at the output end of the hydraulic telescopic rod 78. The expansion plate 90 moves through the U-shaped support plate 91. The expansion plate 90 has an arc-shaped expansion groove 92. 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 installed at the top of the push block 74.

[0048] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The hydraulic telescopic rod 78 pushes the expansion plates 90 at both ends of the lifting frame 70 to move. 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-shaped expansion rod 93 through the arc-shaped expansion groove 92. The arc-shaped expansion groove 92 drives the pushing block 74 at the top of the support base 73 to move towards the side of the lifting frame 70 through the arc-shaped expansion rod 93. The pushing block 74 carries the expansion column 77 through the four sides of the lifting frame 70 and into the lifting ring at the top of the heavy truck battery body 11, accurately and stably locking the lifting frame 70 into the lifting ring of the heavy truck battery body 11.

[0049] Working principle: The heavy-duty truck is driven to the bottom of the battery swapping station body 10. The lifting frame 70 is aligned with the center of the top lifting ring of the heavy-duty truck battery body 11. The expansion plates 90 at both ends of the lifting frame 70 are pushed by 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-shaped expansion rod 93 through the arc-shaped expansion groove 92. The arc-shaped expansion groove 92 drives the pushing block 74 at the top of the support base 73 to move towards the side of the lifting frame 70 through the arc-shaped expansion rod 93. The pushing block 74 carries the expansion column 77 through the four sides of the lifting frame 70 and into the lifting ring at the top of the heavy-duty truck battery body 11. The lifting frame 70 is accurately and stably locked into the lifting ring of the heavy-duty truck battery body 11. There is 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.

[0050] After the lifting frame 70 provides stable support for the heavy truck battery body 11, the servo motor 28 drives one of the fixed gears 24 to rotate. The four fixed gears 24 cooperate 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 moves upward, the lifting block 23 drives the loop-shaped movable plate 22 to move upward synchronously in the fixed column 25. When the connecting rod 29 on the ring chain 21 moves horizontally, the lifting block 23 will move horizontally in the loop-shaped movable plate 22. When the connecting rod 29 on the ring chain 21 moves downward, the lifting block 23 drives the loop-shaped movable plate 22 to move downward synchronously in the fixed column 25.

[0051] When the lifting block 23 and the U-shaped movable plate 22 move down synchronously, the lifting block 23, through the lifting plate 71, carries the lifting frame 70 down to the lifting ring of the heavy truck battery body 11. During the descent, the U-shaped movable plate 22, through the first connecting plate 31, carries the piston cleaning rod 32 down. The piston cleaning rod 32, along with the piston cleaning plate 34, generates 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 37, and then blows and cleans the debris on the top of the heavy 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 truck battery body 11 in a timely manner, which facilitates the subsequent tiered utilization inspection of the heavy truck battery body 11, and allows for a clear inspection of the top appearance of the heavy truck battery body 11, improving the accuracy of appearance inspection.

[0052] When the lifting block 23 moves horizontally within the U-shaped movable plate 22, it carries the heavy-duty truck battery body 11 horizontally into the battery swapping station body 10. At this time, the arc-shaped scraper blade in the swing scraper assembly swings and cleans the sides of the heavy-duty truck battery body 11. The fixed gear 24 drives the fixed rotating rod 64 to rotate, which in turn drives the third bevel gear 65 to rotate. The third bevel gear 65 meshes with the fourth bevel gear 66, which drives the rotating rod 67 to rotate synchronously. The rotating rod 67 carries the bottom rotating cylinder 63 to rotate stably. During rotation, the rotating cylinder 63 carries the rack plate 61 on the arc-shaped moving rod 83 through the S-shaped rotating groove 68, which moves up and down within the arc-shaped limiting plate 80. During the reciprocating up and down movement, the rack plate 61 meshes with the rotating rod 63 during the up and down movement. The drive gear 62 on shaft 69 rotates, and the drive gear 62 carries the arc-shaped scraper brush 60 to perform side cleaning on the heavy truck battery body 11. In addition, when the heavy truck battery body 11 descends in the battery swapping station body 10, the arc-shaped scraper brush 60 also scrapes the heavy truck battery body 11 as it descends. Throughout the process, the arc-shaped scraper brush 60 scrapes and cleans the heavy truck battery body 11 in both horizontal and vertical movements. The combination of multiple motions greatly improves the cleaning effect, expands the contact area and contact time between the heavy truck battery body 11 and the arc-shaped scraper brush 60, and greatly improves the scraping effect on the heavy truck battery body 11. This ensures that the heavy truck battery body 11 is thoroughly and completely cleaned after entering the battery swapping station body 10, which facilitates the subsequent testing of the heavy truck battery body 11 for reuse.

[0053] When the lifting block 23 and the loop-shaped movable plate 22 move upward synchronously, the cleaning cylinder 30 is filled with air through the air inlet pipe 36. After entering the battery swapping station body 10, the heavy truck battery body 11 moves downward again with the ring chain 21. Similarly, the cleaning rod, together with the cleaning nozzle 35, cleans the top of the heavy truck battery body 11 again. After the heavy truck battery body 11 enters the designated position in the battery swapping station body 10, the metal port of the heavy truck battery body 11 enters the cleaning hole 12. After insertion, the lifting frame 70 contacts and limits the lifting ring on the top of the heavy truck battery body 11 for support. The metal port is cleaned by the interface sweeping component. The first bevel tooth on the rotating shaft 53 is driven by the rotating motor 50. The rotating wheel 54 engages with the second bevel gear 56, causing 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-shaped connecting rod 52 to rotate. During the rotation of the Z-shaped connecting rod 52, the swing rods 57 on both sides swing synchronously. The swing rods 57 drive the L-shaped cleaning brush 15 to swing back and forth in the cleaning hole 12. The L-shaped cleaning brush 15 swings back and forth to clean the metal port, removing fine sand and impurities from the metal port. This facilitates subsequent operation and testing of the metal port of the heavy truck battery body 11, and facilitates accurate testing of the voltage, resistance, etc. inside the heavy truck battery body 11.

[0054] The lifting frame 70 moves to its reset position along with the ring chain 21. At this time, the lifting block 23 and the loop-shaped movable plate 22 move upward synchronously. Through the second connecting plate 41, the piston cleaning rod 42 and the piston cleaning plate generate positive pressure inside the cleaning cylinder 40. The compressed air inside the cleaning cylinder 40 enters the blower cleaning seat 43 through the exhaust pipe 46, and then cleans the inside of the metal port through the cleaning nozzle on the blower cleaning seat 43. The metal port is cleaned by blowing air after brushing. When the lifting block 23 moves downward again with the loop-shaped movable plate 22, the cleaning cylinder 40 is filled with gas through the air filling pipe 45, ready for the next stage of cleaning the metal port.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. 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.
